Detailed Description

The present application will be described in further detail with reference to the following drawings and examples. It is to be noted that the following examples are only illustrative of the present application, and do not limit the scope of the present application. Likewise, the following examples are only some examples and not all examples of the present application, and all other examples obtained by a person of ordinary skill in the art without any inventive work are within the scope of the present application.

Reference in the specification to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the specification. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

The present application sets forth a near-eye display device. The near-eye display device may be an augmented reality or virtual reality device, such as augmented reality or virtual reality glasses. Of course, the near-eye display device may also be other devices that need to be worn on the head, such as glasses, for example, a device that has other functions such as illumination and is wearable on the head, which is not described herein. Augmented reality or virtual reality glasses are described in detail below as examples.

In an example of augmented reality or virtual reality glasses, the near-eye display device may be configured to communicate data to and receive data from an external processing device through a signal connection, which may be a wired connection, a wireless connection, or a combination thereof. However, in other cases, the near-eye display device may be used as a standalone device, i.e., data processing is performed on the near-eye display device itself. The signal connection may be configured to carry any kind of data, such as image data (e.g., still images and/or full motion video, including 2D and 3D images), audio, multimedia, voice, and/or any other type of data. The external processing device may be, for example, a gaming console, a personal computer, a tablet computer, a smart phone, or other type of processing device. The signal connection may be, for example, a Universal Serial Bus (USB) connection, a Wi-Fi connection, a bluetooth or Bluetooth Low Energy (BLE) connection, an ethernet connection, a cable connection, a DSL connection, a cellular connection (e.g., 3G, LTE/4G or 5G), etc., or a combination thereof. Additionally, the external processing device may communicate with one or more other external processing devices via a network, which may be or include, for example, a Local Area Network (LAN), a Wide Area Network (WAN), an intranet, a Metropolitan Area Network (MAN), the global internet, or a combination thereof.

A display assembly, optics, sensors, a processor, and the like may be mounted in the near-eye display device. In the example of augmented reality or virtual reality glasses, the display component is designed to implement the functionality of the virtual reality glasses, for example, by projecting light into the user's eyes, e.g., by projecting light into the user's eyes, overlaying an image on the user's view of their real-world environment. The near-eye display device may also include an ambient light sensor, and may also include electronic circuitry to control at least some of the above-described components and perform associated data processing functions. The electronic circuitry may include, for example, one or more processors and one or more memories.

Referring to fig. 1 to 3, fig. 1 is a schematic structural diagram of a near-eye display device 10 according to an embodiment of the present disclosure, fig. 2 is a schematic structural diagram of a connection structure of a display module 100, a device main body 200, and a strap 300 in fig. 1, and fig. 3 is a schematic structural diagram of another connection structure of the display module 100, the device main body 200, and the strap 300 in fig. 2.

Near-eye display device 10 may implement the functionality of a virtual reality or augmented reality environment in front of the user's eyes. As shown in fig. 1 to 3, the near-eye display device 10 may include: display module assembly 100, device body 200, strap 300, and wearing bracket 400. The display module 100 may be connected to one end of the apparatus body 200, and may present a virtual reality or augmented reality environment under the control of the apparatus body 200. The apparatus main body 200 may be detachably coupled with the wearing bracket 400 so that the user may wear the display module 100 in front of the eyes of the user for use by wearing the bracket 400. Meanwhile, after the main body 200 is detached from the wearing frame 400, the main body 200 may be bent in a direction close to the display module 100. The band 300 may be connected to the other end of the apparatus body 200, and may be used to detachably connect to the display module 100 after the apparatus body 200 is bent, so that the display module 100, the apparatus body 200, and the band 300 may form a ring structure, thereby enclosing the wearing space a.

Thus, the user can wear the display module 100 and the device body 200 on the wrist as a watch to carry the display module through the wearing space a, and the wearing bracket 400 can be worn on the head of the user as glasses to carry the display module, so as to improve the portability of the near-eye display device 10. Of course, when the display module 100 and the device body 200 are worn on the wrist of the user, they may also implement all or part of the functions, so that the display module 100 and the device body 200 may also be used as a smart watch. Compared with a scheme that the near-eye display device 10 can be worn on the head of a user for use, the near-eye display device 10 provided by the embodiment can not only improve the portability of the near-eye display device 10, but also expand the use mode and use scene of the near-eye display device 10.

Referring to fig. 4 to 6, fig. 4 is a schematic view of a connection structure between the display module 100 in fig. 2 and the main device 200 and the wearing bracket 400 in a first position, fig. 5 is a schematic view of a connection structure between the display module 100 in fig. 2 and the main device 200 and the wearing bracket 400 in a second position, and fig. 6 is a schematic view of a structure of the display module 100 in fig. 2.

Display module assembly 100 can be fixed in user's eye the place ahead through wearing support 400, and display module assembly 100 can also rotate with equipment main body 200 and be connected for display module assembly 100 can be used for realizing the function of virtual reality or augmented reality environment when rotating to the first position, can be used for enclosing with equipment main body 200 and bandage 300 jointly and establish formation wearing space A when rotating to the second position. As shown in fig. 4 to 5, when the display module 100 and the apparatus main body 200 are worn on the head of the user by wearing the stand 400, the display module 100 located at the first position may be disposed opposite to the eyes of the user, and the display module 100 located at the second position may be disposed symmetrically with the display module 100 located at the first position with respect to the apparatus main body 200.

In this way, when the user rotates the display module 100 to the second position to form the wearing space a together with the apparatus main body 200 and the band 300, the apparatus main body 200 may be bent in a direction away from the wearing bracket 400 and close to the display module 100. After the device body 200 is bent to form a wearing space a together with the band 300 and the display module 100, one side of the device body 200 connected with the wearing bracket 400 can be away from the wearing space a, so that the detachable parts, the electric connectors, the speaker holes and the like arranged on the side of the device body 200 connected with the wearing bracket 400 are exposed away from the wearing space a, namely, one side of the wrist of the user, and the probability that sweat generated by long-time wearing of the user affects the near-to-eye display device 10 through the parts or the holes is reduced. Specifically, the display module 100 rotates with a first direction X as an axial direction, and the first direction X may be parallel to a length direction of the device body 200 in a flattened state.

Further, the foregoing description about the first position and the second position is only one of the solutions that can be adopted by the present embodiment, and the first position and the second position are not limited thereto. For example, the display module 100 at the second position may also be rotated 90 ° from the display module 100 at the first position, and may not be symmetrically disposed with respect to the main body 200 with respect to the display module 100 at the first position. Of course, the bending direction of the main body 200 is changed along with the change of the second position, and it is only necessary that the main body 200 can enclose the wearing space a together with the display module 100 and the band 300 after being bent.

As shown in fig. 6, the display module 100 may include: an optical lens 110 and a frame 120. The optical lens 110 may be disposed on a frame 120, which may present functions of a virtual reality or augmented reality environment under the control of the device body 200. The frame 120 may be connected with the apparatus main body 200 so that the optical lens 110 may be fixed on the wearing stand 400 through the apparatus main body 200 for use. Meanwhile, the frame 120 may also rotate relative to the device body 200, so that the display module 100 may implement a function of a virtual reality or an augmented reality environment when rotating to the first position, and form a wearing space a when rotating to the second position by enclosing with the device body 200.

The optical lens 110 may be disposed at a side of the frame 120 facing away from the apparatus body 200 and disposed opposite to the apparatus body 200, which may function as a virtual reality or augmented reality environment under the control of the apparatus body 200. For example, optical lens 110 may be an optical waveguide sheet, and may specifically be a planar grating waveguide such as a diffraction grating waveguide, such that near-eye display device 10 may present a virtual reality/augmented reality environment through optical lens 110. Wherein the optical lens 110 may be provided with a light coupling inlet portion and a light coupling outlet portion. The light coupling inlet portion may be disposed opposite to the apparatus body 200, and the light coupling outlet portion may be connected to the light coupling inlet portion, and both may form a light path of the optical lens 110 together. Meanwhile, when the user wears the near-eye display device 10 on the head, the light coupling outlet portion may also be disposed opposite the eyes of the user. In this way, the light emitted from the device body 200 can be coupled into the optical lens 110 from the light coupling inlet portion and transmitted in the optical path, and finally the light can be coupled out of the optical lens 110 at the light coupling outlet portion, and then the light is emitted into the eye of the wearer and imaged on the retina, thereby realizing the function of virtual reality or augmented reality of the near-eye display device 10. The above is only a simple description of the basic function of the optical waveguide sheet, and the specific optical principle and structure of the optical waveguide sheet can refer to the prior art, which is not described herein again.

Referring to fig. 7 to 10, fig. 7 is a schematic structural view of the frame 120 of fig. 4, fig. 8 is a partially enlarged view of the frame K of fig. 7, fig. 9 is a schematic structural view of a partial cross section of the frame 120 of fig. 7 along vi-vi, and fig. 10 is a schematic structural view of a partial cross section of the display module 100 and the apparatus body 200 of fig. 2 along v-v.

The frame 120 may be used to mount the optical lens 110 such that the optical lens 110 may be rotatably connected with the apparatus body 200 through the frame 120. As shown in fig. 7, the frame 120 may be provided with a frame portion 121 and a bearing portion 122. The frame portion 121 may be square in shape, and the frame portion 121 may further enclose an installation space B for installing the optical lens 110. The bearing part 122 may be disposed in the installation space B, and the bearing part 122 may not only be used to bear the optical lens 110 to improve the assembly convenience of the optical lens 110 and the frame 120, but also be used to be rotatably connected with the apparatus main body 200, so that the frame 120 may be rotated to the first position or the second position.

A positioning post 1211 is further disposed on a side of the frame portion 121 facing away from the installation space B, and the positioning post 1211 may be disposed away from the main body 200 and may be used for detachably connecting with the strap 300, so that the frame 120, the main body 200 and the strap 300 together enclose a wearing space a. As shown in fig. 8, an avoiding groove 1201 may be disposed on a side of the frame portion 121 facing away from the installation space B, the positioning column 1211 may be disposed in the avoiding groove 1201, and the positioning column 1211 may be disposed in a shape of a T. When the strap 300 is connected to the frame 120, the positioning post 1211 can be inserted into the strap 300 and engaged with the strap 300. When the binding band 300 is detached from the frame 120, the binding band 300 may be elastically deformed to provide an escape space for the positioning post 1211 to exit the binding band 300. In this way, when the user needs to carry the display module 100 and the main body 200, the main body 200 can be bent and then connected to the strap 300 by the positioning post 1211, so that the display module 100, the main body 200 and the strap 300 together enclose the wearing space a. When the user needs to assemble the display module 100 and the apparatus main body 200 to the wearing stand 400, the positioning columns 1211 and the straps 300 may be detached, so that the apparatus main body 200 may be restored to a flattened state before being bent, so as to facilitate the assembly of the apparatus main body 200 with the wearing stand 400.

In some embodiments, frame 120 and strap 300 may be assembled using other detachable connections, as long as the detachable connection of frame 120 and strap 300 is possible. For example, frame 120 and strap 300 may be assembled using a detachable connection that is common to watchbands and watches, such as a watch pin, a watch buckle, a metal clasp, and the like. Alternatively, the frame 120 may be provided with a screw hole, and the strap 300 may be provided with a screw, and the strap 300 may be detachably coupled to the frame 120 by screwing the screw into the screw hole. Of course, the detachable connection between the strap 300 and the frame 120 can be realized by a magnetic attraction method, for example, in addition to the detachable connection realized by a mechanical structure, which is not limited in this embodiment.

The side of the bearing part 122 facing away from the device body 200 may be used for placing the optical lens 110, so that the optical lens 110 may be fixed in the installation space B by the bearing part 122. For example, an adhesive may be disposed on one side of the carrier 122 to adhere the optical lens 110 and the carrier 122. Of course, in order to improve the assembling firmness of the optical lens 110 and the frame 120, the optical lens 110 and the frame portion 121 may be subjected to spot-gluing and curing to bond the optical lens 110 and the frame portion 121. As shown in fig. 7 and 9, the bearing portion 122 may further be provided with a light hole 1221, and the light hole 1221 may communicate the optical lens 110 and the apparatus body 200, so that light emitted from the apparatus body 200 may be irradiated onto the optical lens 110 through the light hole 1221. In some embodiments, in addition to the manner of forming the light hole 1221, the carrying portion 122 may also be designed to be partially transparent or fully transparent, so that the light emitted from the device main body 200 can be irradiated onto the optical lens 110, and only the light transmittance required for the near-eye display device 10 to realize virtual reality or augmented reality needs to be satisfied.

A side of the bearing part 122 close to the apparatus body 200 may be provided with an annular convex rim 1222, and the annular convex rim 1222 may be protrudingly provided outside the installation space B, which may be used for rotational connection with the apparatus body 200. As shown in fig. 9 to 10, the annular flange 1222 may be disposed around the light-transmitting hole 1221, and the annular flange 1222 may further surround a connection space C formed to communicate with the light-transmitting hole 1221. The connection space C may be used to receive a corresponding mating component on the device body 200 to facilitate the rotational connection of the annular flange 1222 to the device body 200. Wherein, a side of the annular convex edge 1222 in the connecting space C may be provided with an annular groove 12221. The matching part on the device main body 200 may be disposed in the ring-shaped clamping groove 12221, and may be clamped with the inner side wall of the ring-shaped clamping groove 12221 in the first direction X, so as to prevent the device main body 200 from coming off from the connection space C, and improve the reliability of the rotational connection between the frame 120 and the device main body 200. Meanwhile, a partial region of the ring-shaped clamping groove 12221 may also be communicated with the mounting space B to provide an avoidance space for rotation of the fitting part of the main device body 200, so as to avoid interference between the fitting part of the main device body 200 and the frame 120 during rotation. Of course, if the ring slot 12221 has enough space, the ring slot 12221 may not communicate with the installation space B.

Referring to fig. 11 to 12 in conjunction with fig. 3, fig. 11 is a schematic structural diagram of the apparatus main body 200 in fig. 2, and fig. 12 is a schematic exploded structural diagram of the apparatus main body 200 in fig. 11.

One end of the device body 200 may be connected to the frame 120, and the device body 200 may be bent in a direction approaching the frame 120 in a flattened state, so that the device body 200 may surround the display module 100 and the strap 300 to form a wearing space a. As shown in fig. 11 to 12, the apparatus body 200 may be provided with a plurality of cases 210, a flattening assembly 220, and an electronic device 230. The plurality of housings 210 may be connected in sequence, and one of two adjacent housings 210 may rotate in a direction approaching or separating from the other, so that the apparatus body 200 can be bent in a direction approaching the display module 100. A flattening assembly 220 may be disposed on the housings 210, which may be used to provide a force to limit the rotation between two adjacent housings 210, i.e., to limit the bending of the apparatus body 200, so as to maintain the flattened state of the apparatus body 200. Electronics 230 may be disposed within housing 210, which may be used to implement the desired functionality of near-eye display device 10.

The aforementioned flat state of the device main body 200 may be a state in which the sides of the plurality of housings 210 facing away from the wearing stand 400 are flush with each other in the first direction X, that is, the plurality of housings 210 are arranged in a line in the first direction X. In some embodiments, the flat state of the device main body 200 may also be designed according to the requirement, and not only the plurality of housings 210 are completely flush with each other, but also the plurality of housings 210 may be arranged and connected in an arc shape, and only after the device main body 200 is detached from the wearable bracket 400, the device main body can be bent and form the wearable space a together with the display module 100 and the strap 300.

The number of the housings 210 may be four, and the four housings 210 may be a first housing 211, a second housing 212, a third housing 213, and a fourth housing 214, respectively. As shown in fig. 3 and 11, the first housing 211, the second housing 212, the third housing 213, and the fourth housing 214 may be sequentially connected. Wherein the first housing 211 may be located at one end of the apparatus body 200, which may be used to rotatably connect with the frame 120. The fourth housing 214 may be located at the other end of the apparatus body 200, which may be used to connect with the band 300. Meanwhile, one of two adjacent housings 210 among the four housings 210 may be rotated in a direction approaching or separating from the other, that is, the second housing 212 may be rotated in a direction approaching or separating from the first housing 211, the third housing 213 may be rotated in a direction approaching or separating from the second housing 212, and the fourth housing 214 may be rotated in a direction approaching or separating from the third housing 213.

Thus, the bending of the device main body 200 in the direction close to the display module 100 can be achieved by the rotation between the four housings 210, and the strap 300 can be displaced in the direction close to the frame 120 after the device main body 200 is bent, and then detachably connected to the frame 120, so that the display module 100, the device main body 200, and the strap 300 together enclose the wearing space a. Of course, in some embodiments, the number of the housing 210 may also be not limited to four, and the number may be selected according to the required mounted electronic device 230 and the design length of the apparatus main body 200, such as two, three, five or more, which is not limited in this embodiment. It should be noted that the above-mentioned "housing", "first housing", "second housing", "third housing", and "fourth housing" may be interchanged with each other, for example, the "first housing" may also be referred to as "second housing", and may also be referred to as "housing".

Referring to fig. 13 to 14 in conjunction with fig. 9 to 10, fig. 13 is an assembly diagram of the first housing 211 in fig. 11, fig. 14 is a partially enlarged view of a portion L in fig. 13, fig. 15 is a partial sectional structure diagram of another embodiment of the frame 120 and the first housing 211 in fig. 10, and fig. 16 is a partial sectional structure diagram of another embodiment of the frame 120 and the first housing 211 in fig. 10.

The first housing 211 may be located at one end of the apparatus body 200, and one side thereof may be used to be rotatably coupled with the frame 120 and the other opposite side thereof may be used to be rotatably coupled with the second housing 212. As shown in fig. 13, the first housing 211 may be provided with a first cover 2111 and a first case 2112. The first cover 2111 may cover the first box 2112, and enclose with the first box 2112 to form an accommodating space D, so as to mount the electronic device 230 using the accommodating space D. The first cover 2111 may be used to rotatably connect with the frame 120, so that the frame 120 may rotate relative to the first housing 211. The first case 2112 may be adapted to be rotatably coupled to the second housing 212 such that the second housing 212 may be rotated in a direction toward or away from the first housing 211.

One side of the first cover 2111 may be provided with an annular retaining wall 2113 and a catch 2114 connected thereto. As shown in fig. 9, 10 and 14, the annular retaining wall 2113 may be disposed in the connecting space C, that is, the annular protruding edge 1222 may be sleeved on the annular retaining wall 2113, and the annular protruding edge 1222 and the annular retaining wall 2113 can rotate relative to each other in the first direction X as an axis direction, so as to realize the rotation of the frame 120 relative to the first housing 211. Meanwhile, in order to reduce friction between the annular retaining wall 2113 and the annular flange 1222, the first housing 211 may further be provided with a rotation ring 2115, and the rotation ring 2115 may be disposed between the annular retaining wall 2113 and the annular flange 1222 and sleeved on the annular retaining wall 2113. Wherein the rotation ring 2115 can space the annular retaining wall 2113 from the annular flange 1222 to reduce the contact area between the annular retaining wall 2113 and the annular flange 1222. When the frame 120 is rotated between the first position and the second position, the annular flange 1222 can be rotated relative to the annular wall 2113 by the rotation ring 2115.

In order to prevent the rotating ring 2115 from being displaced in the first direction X by the rotation of the frame 120, the annular retaining wall 2113 may be further provided with a first retaining groove 21131, and the annular flange 1222 may be provided with a second retaining groove 12222. The rotating ring 2115 may have an inner side disposed in the first retaining groove 21131 in contact with the inner wall of the first retaining groove 21131, and an outer side disposed in the second retaining groove 12222 in contact with the inner wall of the second retaining groove 12222. As such, the first and second retaining grooves 21131 and 12222 may limit the displacement of the rotating ring 2115 in the first direction X. The rotating ring 2115 may be made of metal, and the rotating ring 2115 may further be provided with a notch, so that a partial region of the rotating ring 2115 is broken, and the shape may be similar to a "C" shape structure. Compared with a complete ring-shaped structure, when the rotating ring 2115 is assembled with the annular retaining wall 2113 and the annular convex edge 1222, the deformation amount of the disconnected rotating ring 2115 is higher, and a sufficient avoiding space can be provided for the assembly of the three parts, so that the assembly of the three parts is facilitated.

The buckle 2114 may be on a side of the annular retaining wall 2113 away from the first cover 2111, and the buckle 2114 may be further disposed in the annular groove 12221, and may be clamped with an inner side wall of the annular groove 12221 in the first direction X. The buckle 2114 may have a certain elastic deformation capability, so that when the buckle 2114 is inserted into the connection space C along with the annular retaining wall 2113, the buckle may abut against one side of the annular protruding edge 1222 located in the connection space C, and elastically deform to provide an avoidance space for the insertion of the annular retaining wall 2113. When the annular retaining wall 2113 is inserted in place, the buckle 2114 can be restored to the annular clamping groove 12221 under the action of elastic force, and is clamped with the inner side wall of the annular clamping groove 12221, so that the annular retaining wall 2113 is prevented from being pulled out of the connecting space C. In this embodiment, the number of the catches 2114 may be two, and the two catches 2114 may be symmetrically disposed about the first direction X. In some embodiments, the number of the clasps 2114 may also be set according to requirements, which is not limited in this embodiment.

In order to allow the light emitted from the device body 200 to be transmitted to the optical lens 110 through the first housing 211, the first cover 2111 may be provided with a first notch 21111, and the first container 2112 may be provided with a second notch 21121. As shown in fig. 13, when the first cover 2111 and the first box 2112 are assembled, the first notch 21111 and the second notch 21121 can form a complete circular hole, and the annular retaining wall 2113 can be disposed around the circular hole, so that the light emitted from the electronic device 230 in the accommodating space D can be irradiated onto the optical lens 110 through the circular hole and the light-transmitting hole 1221 of the frame 120. In some embodiments, the annular retaining wall 2113 may be disposed on the first cover 2111 in only a partial region, and the other partial region may be disposed on the first box 2112, only after the first cover 2111 and the first box 2112 are assembled, the two partial regions may form the complete annular retaining wall 2113. Alternatively, the annular retaining wall 2113 may be directly disposed on the first box 2112.

In some embodiments, the positions of the annular ledge 1222 and the annular wall 2113 can be interchanged. That is, the annular flange 1222 may be disposed on the first cover 2111, and the annular retaining wall 2113 may be disposed on the frame 120. Accordingly, the positions of the tabs 2114 and the ring slot 12221 may also be varied. In this manner, the rotational connection of the frame 120 and the first housing 211 may still be achieved. In some embodiments, the positions of catch 2114 and ring slot 12221 may also be interchanged. That is, the side of the annular flange 1222 facing away from the bearing portion 122 may be provided with a catch 2114, and the side of the annular retaining wall 2113 adjacent to the annular flange 1222 may be provided with an annular groove 12221. Thus, when the annular flange 1222 is disposed on the annular retaining wall 2113, the locking clip 2114 can still be disposed in the annular locking groove 12221, so as to achieve the rotational connection between the frame 120 and the first housing 211.

Referring to fig. 15 to 16 in conjunction with fig. 10, fig. 15 is a schematic view of a partial cross-sectional structure of the frame 120 along vi-vi in fig. 7 according to another embodiment, and fig. 16 is a schematic view of the annular ledge 1222 and the annular retaining wall 2113 in fig. 10 matching with each other according to another embodiment.

To achieve the dwell of the frame 120 in the first or second position, the frame 120 is prevented from rotating relative to the first housing 211 under the influence of gravity. The inner side wall of the ring slot 12221 may also have a chamfer 12223. As shown in fig. 10 and 15, the inclined surface 12223 may be disposed on an inner side wall of the ring slot 12221 engaged with the catch 2114. When the frame 120 rotates relative to the device body 200, the catch 2114 slides along the inner sidewall in the annular groove 12221 and is displaced along the inclined surface 12223 in a direction approaching the optical lens 110 during the sliding process. Meanwhile, since the amount of movement between the frame 120 and the apparatus body 200 is limited, the catch 2114 abuts against the inclined surface 12223, i.e., the inner side wall of the ring slot 12221, in the first direction X during the rotation process, so as to increase the friction between the frame 120 and the apparatus body 200, and further limit the rotation of the frame 120. Of course, to effect rotation of the frame 120 in the first and second positions, the abutment force generated by the catch 2114 and the ramp 12223 may be overcome. That is, the frame 120 and the device body 200 may be designed with a certain amount of movement or deformation in advance, so that the frame 120 and the device body 200 may be displaced in the first direction X after being assembled, and the problem that the frame 120 and the device body 200 are locked due to an excessive abutting force and cannot rotate is avoided.

Specifically, the amount of abutment force between the frame 120 and the catch 2114 may vary in a hump curve. When the frame 120 is at the first position or the second position, the value of the abutting force between the frame 120 and the buckle 2114 can be at the position of the wave trough, and along with the rotation of the frame 120, the value of the abutting force between the frame 120 and the buckle 2114 is gradually increased until reaching the position of the wave crest, and finally falls back to the wave trough from the wave crest. For example, if the frame 120 needs to rotate 180 ° from the first position to the second position, the abutment force between the frame 120 and the buckle 2114 gradually increases in the process of rotating from 0 ° to 90 ° and reaches the maximum when rotating to 90 °, so that the rotation of the frame 120 is limited, and the frame 120 is retained in the first position. During the rotation of the frame 120 from 90 ° to 180 °, the abutment force between the frame and the catch 2114 is gradually reduced and reaches a minimum when the frame is rotated to 180 °, so that the frame 120 can be rotated to the second position for parking. In this manner, frame 120 and clasp 2114 may be cycled through every 180 ° of rotation to achieve dwell of frame 120 in the first and second positions, thereby reducing the probability that frame 120 will rotate under forces other than a user's dial.

It should be noted that, when the frame 120 is in the first position or the second position, the value of the abutting force between the frame 120 and the buckle 2114 may be in the valley position is only one of the possible solutions. For example, when the frame 120 is at the first position or the second position, the value of the abutting force between the frame 120 and the buckle 2114 may also be at the position of the peak, and is not limited to the valley, and the specific arrangement manner thereof may be adjusted according to the design requirement, which is not limited in this embodiment. Meanwhile, the numerical limitation of the rotation angle is only one of the available schemes. For example, the frame 120 may only need to rotate by 90 °, 100 °, or 120 ° from the first position to the second position, and is not limited to 180 °, and the specific rotation angle thereof may also be set according to the requirement, which is not limited in this embodiment.

In some embodiments, in addition to limiting the rotation of the frame 120 by providing the chamfer 12223, the rotation of the frame 120 may also be limited by providing a damping member to achieve the dwell of the frame 120 in the first and second positions. As shown in fig. 16, a side of the annular flange 1222 adjacent to the annular retaining wall 2113 may be provided with a first damping member 1222a, and a side of the annular retaining wall 2113 adjacent to the annular flange 1222 may be provided with a second damping member 2113a, and the first damping member 1222a and the second damping member 2113a may be engaged with each other. The first damping member 1222a and the second damping member 2113a may be made of a material with a certain deformation capability, such as rubber, foam, and silicone. As such, the first and second damping members 1222a and 2113a may be in an engaged state when the frame 120 is in the first or second position. When the frame 120 rotates relative to the first housing 211, the first damper member 1222a and the second damper member 2113a may abut to restrict the rotation of the frame 120. Of course, the abutting force generated between the first damping member 1222a and the second damping member 2113a can also be overcome, i.e., the first damping member 1222a and the second damping member 2113a can be elastically deformed to provide the escape space required for the rotation of the frame 120.

In some embodiments, the rotation of the frame 120 may also be limited by providing a stop such as a convex hull, a silicone sleeve, or the like in the annular slot 12221. For example, the ring slot 12221 may be provided with a stop, and the catch 2114 may catch with the stop when the frame 120 is rotated 180 °, such that the frame 120 can only be rotated 180 ° in the same direction to reside in the first position or the second position.

Referring to fig. 17, fig. 17 is a schematic view illustrating another connection structure between the frame 120 and the device body 200 of fig. 2.

In some embodiments, the display module 100 can rotate relative to the apparatus body 200 in the second direction Y, in addition to the first direction X as an axial direction. As shown in fig. 17, the first cover 2111 may be provided with a shaft 2111a, and the frame 120 may be sleeved on the shaft 2111a, so that the frame 120 may rotate relative to the first housing 211 through the shaft 2111a, thereby switching between the first position and the second position. Meanwhile, the dwell of the frame 120 in the first position and the second position may also be achieved by means of a damping member as described above between the frame 120 and the shaft 2111 a. The second direction Y may be perpendicular to the length direction of the device main body 200 in the unfolded state, so that the display module 100 may have a turning action similar to that of a flip phone when rotating, and thus the display module 100 may be turned from the first position to the second position, or from the second position to the first position.

Referring to fig. 18 to 22 in conjunction with fig. 13, fig. 18 is an assembly diagram of the first housing 211 in fig. 13 from another perspective, fig. 19 is a partial enlarged view of a portion M in fig. 18, fig. 20 is an assembly diagram of the second housing 212 in fig. 11, fig. 21 is a partial enlarged view of a portion N in fig. 20, and fig. 22 is a partial sectional structure diagram of the apparatus main body 200 in fig. 2 along v-v.

As shown in fig. 13 and 18-19, a side of the first box 2112 facing away from the annular retaining wall 2113 may be provided with a connecting portion 21122, and the connecting portion 21122 may be used for rotational connection with the second housing 212. Meanwhile, a first installation groove 21123 may be further disposed on a side of the first box 2112 away from the annular retaining wall 2113, and the first installation groove 21123 may be used for installing a partial structure of the flattening assembly 220, so as to cooperate with another partial structure of the flattening assembly 220 on the second housing 212, so as to limit rotation between the first housing 211 and the second housing 212.

The second housing 212 may be rotatably coupled to the first cartridge 2112 via a coupling portion 21122. As shown in fig. 20 to 21, the second housing 212 may also be provided with a second cover 2121 and a second case 2122, and the second cover 2121 may also be covered on the second case 2122 and form a further accommodating space D together with the second case 2122 for accommodating the electronic device 230. Here, one side of the second case 2122 may be provided with a receiving groove 21221, and the receiving groove 21221 may be used to receive the connection portion 21122. Meanwhile, the second case 2122 may further include a rotating shaft 21222, and the rotating shaft 21222 may be disposed in the receiving groove 21221 and connected to an inner sidewall of the receiving groove 21221. The rotational shaft 21222 may be configured to be rotatably coupled to the coupling portion 21122 to allow rotation between the first housing 211 and the second housing 212.

As shown in fig. 22, after the connecting portion 21122 is fitted into the receiving groove 21221, the rotating shaft 21222 may be inserted through the second case 2122 and the connecting portion 21122, so that the connecting portion 21122 can rotate relative to the second case 2122 via the rotating shaft 21222. The rotational shaft 21222 may be a screw, and a region of the rotational shaft 21222 contacting the second housing 2122 is threaded, so that the rotational shaft 21222 can be screwed to the second housing 212. Meanwhile, a region of the rotation shaft 21222 contacting the connection portion 21122 may have a smooth surface so that the connection portion 21122 is rotated by the rotation shaft 21222. In some embodiments, the rotation manner between the first housing 211 and the second housing 212 may also be not limited to the use of the rotation shaft 21222, and the specific rotation connection manner may also be selected according to actual requirements, only that the first housing 211 and the second housing 212 can rotate.

As shown in fig. 21, in order to cooperate with a portion of the flattening assembly 220 on the first housing 211, a second mounting groove 21223 may be further provided at a side of the second case 2122 where the receiving groove 21221 is provided, and the second mounting groove 21223 may be used to mount a portion of the structure of the flattening assembly 220. Wherein the second mounting slot 21223 may be disposed opposite the first mounting slot 21123 when the first and second housings 211 and 212 are in the flattened state, such that a portion of the flattening assembly 220 in the first mounting slot 21123 and a portion of the flattening assembly 220 in the second mounting slot 21223 may cooperate to provide a force to maintain the flattened state of the first and second housings 211 and 212. When first housing 211 and second housing 212 need to rotate, first housing 211 or second housing 212 can be pushed to rotate against the force of flattening assembly 220 to realize bending of device body 200.

Referring to fig. 23 to 25 in conjunction with fig. 19 and 21, fig. 23 is a partial sectional view of the main body 200 of fig. 11 taken along line iv-iv, fig. 24 is a partial enlarged view of O in fig. 3, and fig. 25 is a sectional view of another embodiment of the flattening assembly 220 of fig. 23.

As shown in fig. 19, 21, and 23 to 24, the flattening assembly 220 may be provided with a first connector 221 and a second connector 222. The first connector 221 may be disposed in the first mounting groove 21123, the second connector 222 may be disposed in the second mounting groove 21223, and the first connector 221 and the second connector 222 may be magnetically connected to provide a magnetic force to limit the rotation between the first housing 211 and the second housing 212, so as to maintain the flat state of two adjacent housings 210. When the device body 200 needs to be bent, a user may break the first housing 211 or the second housing 212 to overcome the magnetic force generated by the first connector 221 and the second connector 222 to push the first housing 211 or the second housing 212 to rotate, thereby bending the device body 200. When the strap 300 is detached from the frame 120, the first and second housings 211 and 212 may rotate under the magnetic force generated by the first and second connectors 221 and 222, so that the first and second housings 211 and 212 may be flattened by the magnetic force, thereby maintaining the flattened state of the two adjacent housings 210. The first connecting member 221 and the second connecting member 222 may be magnets to improve the magnetic connection strength of the two members. Of course, only one of the first connector 221 and the second connector 222 may be a magnet, and the other may be an object that can be attracted by magnetic force, such as metal.

In some embodiments, in addition to maintaining the flat state of first housing 211 and second housing 212 through a magnetic attraction connection manner, the flat state of first housing 211 and second housing 212 may also be maintained through a deformation force. As shown in fig. 25, the flattening assembly 220 may be provided with a guide 223, a slider 224, and an elastic member 225. Wherein, one end of the guide 223 may be used to connect with the first container 2112, and the guide 223 may be arc-shaped, and may further have a guide space 2231 therein. One end of the slider 224 may be used to connect with the second case 2122, and the other end of the slider 224 may be disposed in the guide space 2231 and may slide along the guide 223 in the guide space 2231. The elastic member 225 may be disposed in the guide space 2231, and the elastic member 225 may be connected with the guide 223 and the slider 224, respectively. When the sliding member 224 slides relative to the guiding member 223, the elastic member 225 can be compressed or stretched by the sliding member 224, so as to generate a deformation force, so that the sliding member 224 can be reset by the deformation force after sliding.

As such, when first housing 211 and second housing 212 are in the flattened state, elastic member 225 may be in an undeformed state. When first housing 211 and second housing 212 are forced to bend such that sliding member 224 slides along guiding member 223 in guiding space 2231, elastic member 225 may be elastically deformed to provide a deformation force for maintaining first housing 211 and second housing 212 in a flattened state. Of course, the deformation force generated by the elastic member 225 may be overcome, so that the user may break the first and second housings 211 and 212 to bend, and may connect the frame 120 with the bands 300 after the first and second housings 211 and 212 are bent, thereby maintaining the bent state of the first and second housings 211 and 212. When the binding band 300 is detached from the frame 120, the first shell 211 and the second shell 212 can be restored to the flat state under the driving of the deformation force.

In addition, in order to prevent the sliding member 224 from being removed from the guide space 2231, the flattening assembly 220 may be provided with a corresponding limit structure. For example, the flattening assembly 220 may be further provided with a pin, and the pin may be fixedly disposed on the guide 223. Accordingly, the slider 224 located in the guide space 2231 may be provided with a groove. In this way, the sliding of the sliding member 224 can be limited by inserting the latch into the groove, so as to prevent the sliding member 224 from falling out of the guide space 2231. Wherein, the length of the groove is the sliding stroke of the sliding piece 224.

The third housing 213 and the fourth housing 214 may have the same structure as the second housing 212, and the third housing 213 and the second housing 212 may be rotatably connected, and the fourth housing 214 and the third housing 213 may be rotatably connected, and may also be rotatably connected to the first housing 211 and the second housing 212. Meanwhile, between third housing 213 and second housing 212, and between fourth housing 214 and third housing 213, there may also be provided respective flattening assemblies 220 for maintaining the flattened state of second housing 212, third housing 213, and fourth housing 214. The specific structures and the rotational connection manners of the second housing 212 and the third housing 213, and the third housing 213 and the fourth housing 214 can refer to the first housing 211 and the second housing 212 in the foregoing embodiments, which are not described herein again.

Electronics 230 may be disposed within housing 210, which may be used to implement the functionality of near-eye display device 10. As shown in fig. 12, the electronic device 230 may include: an optical engine 231, a main board 232, a battery 233, and a speaker 234. The optical engine 231 may be disposed in the accommodating space D of the first housing 211, and the emitted light may irradiate the optical lens 110 for imaging. The main plate 232 may be disposed in the accommodating space D of the second housing 212. The battery 233 may be disposed in the receiving space D of the third case 213. The speaker 234 may be disposed in the accommodating space D of the fourth housing 214. Meanwhile, the optical engine 231, the main board 232, the battery 233 and the speaker 234 may be electrically connected through a flexible circuit board. Of course, the electronic device 230 is not limited to include the aforementioned devices, and may also include more devices that can be loaded by the near-eye display apparatus 10, and the arrangement of the respective devices may also be not limited to the aforementioned manner, and the specific arrangement manner thereof may be adjusted according to design requirements, which is not limited in this embodiment.

Referring to fig. 26 to 28 in conjunction with fig. 2 and 8, fig. 26 is a schematic structural view of the strap 300 in fig. 3, fig. 27 is a partial enlarged view of a point P in fig. 11, and fig. 28 is a partial enlarged view of a point Q in fig. 2.

One end of the strap 300 may be connected to the fourth case 214, and the other end of the strap 300 may be detachably connected to the frame 120 after the apparatus body 200 is bent, so that the display module 100, the apparatus body 200, and the strap 300 together enclose a wearing space a. As shown in fig. 26 to 27, one end of the strap 300 may be rotatably coupled with the fourth housing 214 such that the strap 300 may be rotated relative to the fourth housing 214 to facilitate the detachable coupling of the strap 300 with the frame 120. For example, one end of the band 300 may be provided with the latch 310, and the fourth housing 214 may be provided with the corresponding first fitting groove 2141, and the latch 310 may be disposed in the first fitting groove 2141, so that the band 300 may be not only rotatably coupled with the fourth housing 214 but also detachably coupled with the fourth housing 214. In this way, when the user wears the apparatus main body 200 on the head for use, the band 300 can be detached for storage. The specific structure of the elastic needle 310 can refer to the ear-growing needle in the prior art, which is not described herein.

The other end of the strap 300 may be provided with a positioning hole 320, and the number of positioning holes 320 may be plural. As shown in fig. 8 and 26, a plurality of positioning holes 320 may be sequentially arranged in the length direction of the strap 300, which may be used to detachably connect with the positioning posts 1211 on the frame 120. When the strap 300 is connected to the frame 120, the positioning post 1211 can be inserted into the positioning hole 320 and engaged with the strap 300. Meanwhile, the user can select the corresponding positioning hole 320 for connection according to the size of the wrist. When the strap 300 and the frame 120 are detached, the strap 300 can be elastically deformed to provide an escape space for the positioning post 1211 to exit from the positioning hole 320.

Further, in order to house the strap 300, when the strap 300 is detached from the frame 120, the other end of the strap 300 may be detachably connected to the first housing 211 so that the entire strap 300 may be attached to the apparatus body 200. As shown in fig. 2, 26 and 28, a side of the first box 2112 facing away from the first cover 2111 may be provided with a position-limiting post 21124, and the position-limiting post 21124 may be inserted into the positioning hole 320 of the strap 300 and clamped with the strap 300. Accordingly, the strap 300 may also be elastically deformed to provide an escape space for the retaining post 21124 to exit the positioning hole 320, so as to achieve the detachable connection of the first housing 211 and the other end of the strap 300. As such, the band 300 may be received by the apparatus body 200 so that the band 300 may be attached to the plurality of cases 210. In this embodiment, the material of the bandage 300 may be a flexible skin-friendly material, such as soft rubber, silica gel, hemp rope, or a corresponding composite material, so as to improve the wearing comfort of the user.

In some embodiments, the design of the strap 300 may be eliminated when the number of the cases 210 is sufficiently large to allow the case 210 at the end to be connected to the frame 120 after the device body 200 is bent. Meanwhile, the display module 100 and the device body 200 may also be enclosed to form a "C" shaped structure, rather than being limited to form a complete ring-shaped structure. If the display module 100 and the main body 200 enclose to form a "C" shaped structure, the main body 200 may further include a component for limiting the rotation of two adjacent housings 210, so that the housings 210 may reside after rotating. Here, the design of the first damping member 1222a and the second damping member 2113a for residing may be referred to in the previous embodiment, that is, one of the rotating shaft 21222 and the connecting portion 21122 is provided with the first damping member 1222a, and the other is provided with the second damping member 2113a, so that after the connecting portion 21122 rotates relative to the rotating shaft 21222, the residing of the adjacent two housings 210 at different positions can be achieved by the damping force between the first damping member 1222a and the second damping member 2113 a.

Referring to fig. 29 to 31, fig. 29 is a schematic view of a connection structure of the display module 100, the apparatus main body 200 and the strap 300 in fig. 2 according to another embodiment, fig. 30 is a schematic view of another connection structure of the display module 100, the apparatus main body 200 and the strap 300 in fig. 29, and fig. 31 is a schematic view of another connection structure of the display module 100, the apparatus main body 200 and the strap 300 in fig. 30.

Since the length of the apparatus body 200 is limited, the band 300 is designed to connect the apparatus body 200 and the display module 100, and the longer band 300 is not conveniently accommodated after being detached from the frame 120, and if the band 300 is attached to the apparatus body 200 to be accommodated as in the previous embodiment, the functional design of the apparatus body 200 is affected. For example, the side of the second case 2122 facing away from the second cover 2121 can be used to design a touch pad so that a user can perform a touch operation. The storage of the band 300 attached to the device body 200 blocks an area for designing a touch pad, resulting in a limitation in functional design of the device body 200.

For this reason, in some embodiments, the device main body 200 may further be stretchable and may be bent after being stretched to form the wearing space a together with the display module 100 and the band 300, so that the design length of the band 300 is reduced by extending the length of the device main body 200, and the longer band 300 is prevented from affecting the functional design of the device main body 200. As shown in fig. 29 to 31, the apparatus main body 200 may be provided with a bending piece 250 and a stopper assembly 260 in addition to the first, second, third and fourth housings 211, 212, 213 and 214 connected in sequence. Among them, the bending member 250 may be used to realize sliding of the first and second housings 211 and 212, so that the distance between the first and second housings 211 and 212 is increased or decreased, thereby realizing extension and contraction of the apparatus main body 200. Meanwhile, the bending member 250 may also be used to bend after the distance between the first housing 211 and the housing 212 is increased, that is, the device body 200 is elongated, so as to realize bending of the device body 200. The limiting member 260 may be used to provide a force to limit the sliding of the first and second housings 211 and 212, that is, the expansion and contraction of the apparatus main body 200, so as to maintain the flattened state of the apparatus main body 200. In addition, the structures of the first housing 211, the second housing 212, the third housing 213 and the fourth housing 214 are the same as or similar to those of the foregoing embodiments, and the second housing 212, the third housing 213 and the fourth housing 214 can still be rotatably connected as in the foregoing embodiments, and can maintain the flat state under the force provided by the flat component 220, which is not described herein again.

Referring to fig. 32 to 35, fig. 32 is a schematic structural view of the first box 2112 in fig. 30, fig. 33 is a schematic partial structural view of the bending member 350 in fig. 30, fig. 34 is a schematic structural view of the connection between the first box 2112 and the bending member 350 in fig. 30, and fig. 35 is a schematic structural view of the connection between the first box 2112, the second box 2122, the bending member 250 and the position limiting assembly 260 in fig. 30.

As shown in fig. 32 to 34, opposite sides of the first container 2112 in the accommodating space D may be provided with a second fitting groove 21125 and a sliding groove 21126 communicating with each other, and the extending directions of the second fitting groove 21125 and the sliding groove 21126 may be perpendicular, so that both may be arranged in an "L" shape. Wherein the second fitting slot 21125 may be used to provide an escape space for the installation of the bending member 250, such that one end of the bending member 250 may be installed into the sliding slot 21126 through the second fitting slot 21125. Meanwhile, in order to facilitate the connection of the bending member 250 with the second housing 212, an opening 21127 may be further disposed at a side of the first case 2112 close to the second housing 212, such that the other end of the bending member 250 can extend out of the accommodating space D through the opening 21127 to be slidably connected with the second housing 212. In addition, opposite sides of the first case 2112, on which the second fitting groove 21125 and the sliding groove 21126 are provided, may be further provided with fixing grooves 21128, and the fixing grooves 21128 may be used for mounting a partial structure of the stopper assembly 260.

Opposite sides of the end of the bending member 250 may be provided with protrusions 251, and the protrusions 251 may be installed into the slide groove 21126 through the second fitting groove 21125 and may slide along the slide groove 21126. The protrusion 251 can also be engaged with the inner wall of the sliding groove 21126 after sliding, so as to prevent the bending member 250 from being removed from the accommodating space D. Meanwhile, in order to prevent the projection 251 from slipping out of the second fitting groove 21125, the second fitting groove 21125 may be subjected to a sealing process after the bent piece 250 is fitted to the first container 2112. Accordingly, the second case 2122 of the second housing 212 may also be provided with the same structure as the first case 2112, such that the other end of the bending member 250 can be slidably connected with the second case 2122, which is not described herein.

In this manner, before the apparatus main body 200 is not bent, the bending piece 250 may be accommodated in the accommodating space D of the first and second housings 211 and 212. When the main body 200 needs to be bent, the first housing 211 or the second housing 212 may be pulled, so that the bending member 250 may slide out from the accommodating space D for bending, thereby achieving the purpose of bending the main body 200 after being extended. The material of the bending member 250 may be soft glue, so that the bending member 250 may have a bending property. Meanwhile, a conductive circuit may be embedded in the bending member 250, so that the bending member 250 may also be used to electrically connect the electronic device 230 in the first housing 211 and the second housing 212.

In some embodiments, the bending member 250 may also be not limited to soft glue, but may also be formed of a plurality of rotatably connected housings 210 as in the previous embodiments, so that it can have a bending capability. In addition, in some embodiments, only one of the first housing 211 and the second housing 212 may be slidably connected to the bending member 250, and is not limited to that two adjacent housings 210 are slidably connected to the bending member 250, and only one of the two adjacent housings 210 may be slidable in a direction approaching or departing from the other, so that the apparatus main body 200 may be retractable. Meanwhile, the bending member 250 may also be slidably connected to the outer surface of the first case 2112 and/or the second case 2122, and is not limited to be received in the receiving space D.

Limiting assembly 260 may be used to provide a force to limit the sliding of first housing 211 and second housing 212 and maintain the flattened state of first housing 211 and second housing 212. As shown in fig. 35, the limiting assembly 360 may be provided with a first limiting member 361 and a second limiting member 362. The first limiting member 261 may be disposed in the fixing groove 21128 of the first box 2112, the second limiting member 262 may be disposed in the fixing groove 21128 of the second box 2122, and the first limiting member 261 and the second limiting member 262 may be magnetically connected to provide magnetic force to limit the sliding of the first housing 211 and the second housing 212, and maintain the flat state of the first housing 211 and the second housing 212. When the device main body 200 needs to be extended, a user may overcome the magnetic force generated by the first and second stoppers 261 and 262 to pull the first housing 211 or the second housing 212, so that the device main body 200 may be extended, thereby realizing bending of the device main body 200 after being extended. The first limiting member 261 and the second limiting member 262 may be both magnets to improve the magnetic connection strength of the two members. Of course, only one of the first limiting member 261 and the second limiting member 262 may be a magnet, and the other may be an object that can be attracted by magnetic force, such as metal.

In some embodiments, in order to prevent the first housing 211 and the second housing 212 from being dislocated by an external force, one of the first housing 211 and the second housing 212 may be further provided with a protrusion, and the other one may be provided with a matching recess. When the first retaining member 261 and the second retaining member 262 are magnetically connected, the protrusion may be disposed in the recess, so that the first housing 211 and the second housing 212 may be connected through the protrusion and the recess.

Referring to fig. 36, fig. 36 is a partial structural schematic view of the first box 2112, the second box 2122, the bending element 250 and the position limiting assembly 260 in another embodiment of fig. 35.

In some embodiments, in addition to maintaining the flat state of first and second cases 211 and 212 by means of magnetic force, a deformation force may also be used to maintain the flat state of first and second cases 211 and 212. For example, the position limiting assembly 260 may also be provided with a plug 263, a spring 264, and a pusher 265. As shown in fig. 36, the plug 263 may be provided on the first container 2112, and the plug 263 may be provided with a card slot 2631. The second case 2122 may be provided with a slot 21224 corresponding to the plug 263, and the spring 264 may be provided in the slot 21224. The pushing member 265 may be disposed on the second case 2122, and the pushing member 265 may be connected to the spring 264 and may push the spring 264 to be elastically deformed. Thus, when the first case 2112 and the second case 2122 are connected, the plug 263 can be inserted into the slot 21224 to abut against the spring 264, so that the spring 264 is elastically deformed to provide a space for the plug 263 to be inserted. When the plug 263 is inserted into the position, the spring 264 can be engaged with the plug 263 in the slot 2631 of the plug 263. When the first case 2112 and the second case 2122 need to slide, the spring 264 can be elastically deformed by pressing the pushing element 265 to provide a space for the plug 263 to exit the slot 21224, so that the plug 263 can exit the slot 21224, thereby implementing the sliding between the first case 2112 and the second case 2122. Compared with the magnetic connection method, the connection reliability and stability of the first box 2112 and the second box 2122 in the flat state can be improved.

In some embodiments, the bending member 250 may also be disposed between the first housing 211 and the second housing 212, and may be disposed between any two adjacent housings 210 and slidably connected with the two housings 210 to achieve the extension and retraction of the device main body 200. Meanwhile, the bending member 350 may also be not limited to one, for example, the first housing 211 and the second housing 212 may be bent by the bending member 350, and the second housing 212 and the third housing 213 may also be bent by the bending member 350. Similarly, the fourth housing 214 may be rotatably connected to the third housing 213 as in the previous embodiments, or may be telescopically bent with the third housing 213 by the bending member 350. That is, the adjacent housings 210 may be bent by the bending member 350, may be bent by the rotating shaft 21222 in a rotating manner as in the foregoing embodiments, or may be bent by two bending manners at the same time, and the specific connection manner may be adjusted according to design requirements, which is not limited in this embodiment.

In addition, it should be noted that the plurality of shells 210 of the apparatus main body 200 in the present embodiment may also be divided into a plurality of main bodies, and two adjacent main bodies may be slidably connected by the bending member 250. For example, the first housing 211 may constitute one body of the apparatus main body 200, and the second housing 212, the third housing 213, and the fourth housing 214 may constitute another body of the apparatus main body 200, so that adjacent two bodies can be extended and contracted and can be bent after being extended. Alternatively, the first housing 211 and the second housing 212 may constitute one main body of the apparatus main body 200, the third housing 213 and the fourth housing 214 may constitute the other main body of the apparatus main body 200, and the second housing 212 and the third housing 213 may be telescopically bent by the bending member 250, so that adjacent two main bodies may be telescopically extended and bent after being extended. Wherein, along with the difference of casing 210 quantity, the division of main part is also different, only need guarantee between two adjacent main parts that the accessible piece 250 that buckles stretches out and draws back to buckle can.

Referring to fig. 37, fig. 37 is a partial enlarged view of S in fig. 31.

Since the apparatus body 200 can be extended and contracted, the design length of the band 300 can be reduced. When the other end of the strap 300 is detached from the frame 120, the other end thereof may be connected to the fourth housing 214 so that the shorter strap 300 may be fixed to the fourth housing 214 without occupying an area on the first, second, and third housings 211, 212, and 213. As shown in fig. 37, the fourth housing 214 may also be provided with the same position-limiting posts 21124 as those of the first housing 211, so that the fourth housing 214 can be detachably connected to the strap 300 by the position-limiting posts 21124 engaging with the positioning holes 320 of the strap 300.

The wearable stand 400 may be used to carry the display module 100 and the apparatus body 200, so that a user may wear the display module 100 and the apparatus body 200 on the head by wearing the stand 400 to present a virtual reality or augmented reality environment in front of the eyes of the user. As shown in fig. 1, the wearing bracket 400 may be provided with a frame 410 and temples 420. Frame 410 may be worn over the nose of the user, i.e., in front of the user's eyes. Temples 420 may be provided at opposite sides of the frame 410, and the temples 420 may be worn at ears of a user. Thus, the frame 410 and the temple 420 are matched to realize the wearing function of the wearing bracket 400, so that the user can wear the display module 100 and the device main body 200 on the head for use by wearing the bracket 400. In some embodiments, the near-eye display device 10 may be provided with only the display module 100 and the device main body 200, and the wearing stand 400 may be a separate component, and the specific structure of the wearing stand 400 may refer to the existing glasses structure.

Further, the frame 410 may be used to mount corresponding functional lenses, and the temples 420 may be used to detachably connect with the apparatus main body 200. The frame 410 can be used to mount functional lenses such as flat glasses, anti-glare glasses, colored glasses, and myopia glasses, so that the wearing frame 400 can be still worn on the head of a user as common glasses after being detached from the device main body 200. When the display module 100 is worn on the head of a user, it can be disposed opposite to the functional lenses on the frame 410. The temples 420 and the display module 100 may be detachably connected by magnetic attraction, snap, etc. so that the user may replace the wearing bracket 400 or the display module 100 and the device main body 200 with different functions or styles according to the requirement. For example, a magnet may be provided on the temple 420, and a magnet may also be provided on the second cover 2121 of the second housing 212 in the apparatus main body 200, so that the temple 420 may be magnetically attached to the apparatus main body 200.

The near-eye display device 10 provided by the embodiment of the application not only can utilize display module assembly 100 and device main body 200 to realize the virtual reality or augmented reality environment function of near-eye display device 10, but also can extend device main body 200 in the flattening state, and can buckle the device main body 200 after being extended to the direction close to display module assembly 100, so that device main body 200 can enclose with display module assembly 100 together and establish and form wearing space A. In this way, the user can wear the bent device body 200 and the display module 100 on the wrist through the wearing space a to carry the device, thereby improving the portability of the near-eye display device 10.

The above description is only a part of the embodiments of the present application, and not intended to limit the scope of the present application, and all equivalent devices or equivalent processes performed by the content of the present application and the attached drawings, or directly or indirectly applied to other related technical fields, are also included in the scope of the present application.
