All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The core of the invention is to provide an intelligent glasses hinge structure which is convenient to assemble.

Referring to fig. 1 to 28, a first embodiment of a hinge structure (hinge structure for short) for smart glasses according to the present invention includes a plurality of hinge frames 2 sequentially arranged along a predetermined direction, and adjacent hinge frames 2 are hinged by a hinge shaft 6.

In this embodiment, 4 hinge brackets 2 are provided, and in other embodiments, other numbers of hinge brackets 2 may be provided.

Wherein, because each hinge frame 2 is hinged, the hinge frames 2 may not always keep a straight line state, and accordingly, the preset direction may be a straight line or a curve direction.

The hinge shaft 6 is provided with a reset component 5. When the hinge bracket 2 at one end swings to a set angle relative to the hinge bracket 2 at the other end in a preset everting direction, the reset component 5 provides a reset force to the hinge bracket 2, so that the corresponding hinge bracket 2 has a movement tendency opposite to the preset everting direction.

For the preset everting direction, the hinge frame 2 at one end of the hinge structure is a fixed end, the hinge frame 2 at the other end of the hinge structure is a movable end, and the moving direction of the movable end, which changes from the bending limit inward folding state (shown in fig. 15) to the unfolding limit outward folding state (shown in fig. 21) relative to the fixed end, is the preset everting direction.

During the process of everting the hinge structure along the preset everting direction, the restoring elements 5 may or may not start to deform at the same time. The set angle can be defined in particular as the critical value at which all the reduction elements 5 start to deform, and each reduction element 5 is in the deformed state after the hinge structure is turned outwards to the set angle and then turned outwards. In this embodiment, the reset assembly 5 provides a corresponding inward-folding reset force when the reset assembly is in the limit inward-folding state, i.e., the reset assembly is turned outwards.

The hinge shaft 6 is provided with a damping elastic member 7, and the damping elastic member 7 presses at least one hinge bracket 2 to provide a damping force when the corresponding hinge bracket 2 swings.

When being applied to intelligent glasses such as AR glasses, the hinge frame 2 of two tip of hinge structure connects picture frame 1 and mirror leg 3 respectively to make mirror leg 3 pass through hinge structure and rotate and connect in picture frame 1, mirror leg 3 can be for picture frame 1 infolding or turning up. In the wearing process, a user swings the glasses legs 3 along the preset outward turning direction, each hinge frame 2 correspondingly moves along the preset outward turning direction, the deformation degree of the reset assembly 5 is gradually increased, the glasses legs 3 keep the trend of reset movement along the preset inward folding direction, the preset inward folding direction is opposite to the preset outward turning direction, the two glasses legs 3 can be respectively pressed to the head, the two glasses legs 3 clamp the head, the intelligent glasses can be worn in adaptation with different head types, and the wearing applicability and comfort are improved; meanwhile, in the process of turning the temples 3 outwards, the damping elastic members 7 generate friction force to the corresponding hinge brackets 2 as damping force to improve the use hand feeling.

In this embodiment, set up reset component 5 and damping elastic component 7 on articulated shaft 6 in unison, direct 6 department location on articulated shaft reset component 5 and damping elastic component 7 can, can install in unison, the hinge structure's of being convenient for assembly.

Further, the pressing force of the damping elastic member 7 pressing the corresponding hinge bracket 2 is adjustable. Because the pressing force is adjustable, the damping force applied to the hinge frame 2 is adjustable, and the use hand feeling can be adaptively improved according to the requirement.

Further, referring to fig. 4, fig. 10 to fig. 12, at least one pair of adjacent hinge brackets 2 are respectively fixed with a mounting plate 21 to form a plate assembly. The hinge shaft 6 is inserted into each mounting plate 21 along the axial direction, the damping elastic member 7 presses at least two adjacent mounting plates 21 respectively connected to the two hinge brackets 2, and the pressed mounting plates 21 generate friction force when rotating relatively to provide damping force. The provision of the damping force is achieved by the friction between the mounting plates 21, and the damping effect can be ensured. Of course, in other embodiments, friction may be provided as the damping force by damping relative rotation between the resilient member 7 and the mounting plate 21 with which it is in contact.

Further, as shown in fig. 10 and 11, one end of the hinge shaft 6 in the axial direction is provided with an end cap 62, and the damping elastic member 7 is positioned axially between one end of the plate group and the end cap 62. The axial spacing between the end cap 62 and the plate package is adjustable. The pressing force of the damping elastic part 7 on the hinge frame 2 is adjusted by adjusting the axial distance between the end cap 62 and the plate group, so that the operation is convenient.

Further, as shown in fig. 11, the other axial end of the hinge shaft 6 is a threaded rod, a lock nut 63 is screwed on the threaded rod, and the plate assembly is sandwiched between the lock nut 63 and the end cap 62. Specifically, the damping elastic member 7 is a disc spring sleeved on the hinge shaft 6, and may be another spring. In addition, as shown in fig. 10, the damping elastic member 7 may be separated from the plate member and the end cap 62 by a gasket 61 fitted around the hinge shaft 6.

In this embodiment, the hinge shaft 6 is sequentially installed after the elastic component, the damping elastic component 7 and the installation plate 21 along the axial direction, and then the locking nut 63 is connected, so that the assembly of the parts at the hinge shaft 6 is completed, and the operation is convenient. In addition, by screwing the lock nut 63, the axial distance between the lock nut 63 and the end cap 62 is adjusted, and the degree of pressing of the damping elastic member 7 is adjusted, and the damping force is adjusted. Of course, in other embodiments, a thread may be directly disposed in a plate hole of one of the mounting plates 21 to form a threaded plate hole, and the threaded rod on the hinge shaft 6 is directly screwed to the threaded plate hole, so that the damping force of the damping elastic member 7 can be adjusted by adjusting the position where the two are axially connected.

Further, as shown in fig. 11, between at least one pair of adjacent hinge brackets 2, each mounting plate 21 in the plate group is divided into two plate groups 25 and is axially disposed at both ends of the hinge bracket 2, and the return member 5 is disposed between the two plate groups 25.

By arranging the two plate groups 25 at the two ends of the hinge frame respectively, it is ensured that a sufficient space is provided between the two plate groups 25 for installing the reset assembly 5, and meanwhile, the space is filled with the reset assembly 5, so that the connection strength of the whole hinge structure can be improved.

Further, as shown in fig. 11 and 12, in at least one pair of adjacent hinge brackets 2, one hinge bracket 2 is fixedly connected with the hinge shaft 6, and the restoring assembly 5 includes a fixed block 51 fixed on the other hinge bracket 2, a movable block 52 axially slidably connected to the hinge shaft 6, and a restoring elastic member 53 axially pressing the movable block 52 against the fixed block 51. When the hinge frame 2 at one end swings to a set angle relative to the hinge frame 2 at the other end in the preset everting direction, the movable block 52 is matched with the fixed block 51 through the inclined plane, so that the corresponding hinge frame 2 has a movement trend opposite to the preset everting direction.

Specifically, as shown in fig. 19, the fixed block 51 is provided with a fixed inclined surface 512 inclined with respect to the axial direction, and the movable block 52 is provided with a movable inclined surface 522 inclined with respect to the axial direction, and the fixed block and the movable block are kept in fit. When the movable block 52 rotates along with the hinge shaft 6, the fixed block 51 is relatively static, under the push of the fixed inclined plane 512, the movable block 52 axially moves and is away from the fixed block 51 and compresses the reset elastic member 53, and the elastic force of the reset elastic member 53 generates inward-folding reset force through the hinge frame corresponding to the turning capability of the movable inclined plane 522 and the fixed inclined plane 512.

In order to achieve an axial displacement of the movable block 52 without maintaining the circumferential position with the fixed block 51, the movable block 52 is axially slidably connected to the hinge shaft 6, in particular, by a key structure. Alternatively, both ends of the restoring elastic member 53 are fixedly connected to the movable block 52 and the mounting plate 21, respectively, and the movable block 52 can rotate along with the hinge shaft 6 without excessively rotating by the torsional restoring force of the restoring elastic member 53.

As shown in fig. 9 and 10, the fixed block 51 is rotatably sleeved on the hinge shaft 6, and meanwhile, the fixed block 51, the movable block 52 and the elastic restoring element 53 are sequentially sleeved on the hinge shaft 6 along the axial direction.

Through the inclined plane cooperation, can change the axial pressure that resets elastic component 53 that the movable block 52 received into the pressure of perpendicular to the axial to produce the reset effort of perpendicular to the axial to the hinge frame 2 that carries out the evagination, make the hinge frame 2 that carries out the evagination have the motion trend that the inflection resets, can fully distribute the axial space of articulated shaft 6 department and accomplish the assembly of fixed block 51, movable block 52, elastic component 53 that resets and damping elastic component 7, further make things convenient for the assembly.

In addition, the fixed block 51 and the hinge frame 2 are formed by a sheet metal stamping mode or a simple machining mode, and cost can be reduced.

As shown in fig. 4 and 9, the fixed plane 511 and the fixed inclined plane 512 of the fixed block 51 are circumferentially abutted, and the movable plane 521 and the movable inclined plane 522 of the movable block 52 are circumferentially abutted. Specifically, in the extreme folded-in state shown in fig. 15, the fixed plane 511 and the movable plane 521 are in contact abutment in the axial direction; when the movable end of the hinge structure swings in the preset outward-turning direction relative to the fixed end, the movable block 52 rotates while the position of the fixed block 51 is unchanged, the movable inclined plane 522 is attached to the fixed inclined plane 512 to slide, so that the movable block 52 rotates along with the hinge shaft 6, the movable inclined plane 522 drives the movable block 52 to axially move, the degree of compressing the reset elastic part 53 is increased, the driving force for driving the corresponding hinge frame 2 to be folded inwards and reset is also increased, and in addition, the axial distance between the movable plane 521 and the fixed plane 511 is also increased.

In addition, as shown in fig. 16, the fixed block 51 is further provided with a fixed inner limiting surface 513 parallel to the axial direction, the movable block 52 is provided with a movable inner limiting surface 523 parallel to the axial direction, and in the limit folded-in state, the fixed inner limiting surface 513 and the movable inner limiting surface 523 are matched and abutted along the circumferential direction, so that the corresponding hinge frame 2 cannot rotate inwards any more, and the folded-in limiting is performed. In addition, as shown in fig. 9, the hinge brackets 2 are provided with outer limiting surfaces 211, and in the extreme outward-turning state, the outer limiting surfaces 211 between the adjacent hinge brackets 2 are abutted to prevent the corresponding hinge brackets 2 from continuing to turn outward.

In this embodiment, the fixed plane 511 and the movable plane 521 are abutted in cooperation, so that the stability of installation between the movable block 52 and the fixed block 51 when the hinge structure is in the limit folded-in state without using the smart glasses can be improved.

Preferably, the first side plate 49 is a U-shaped plate, two opposite walls of the U-shaped plate are provided with axial slots 492, and the second side plate 45 is mounted on a lateral opening of the first side plate 49. Wherein, each middle hinge cover is provided with a shaft groove 492 to fixedly connect with a hinge shaft 6 respectively.

In the process that the hinge frame 2 is installed in the first side plate 49 through the lateral opening of the first side plate 49, the hinge shaft 6 can synchronously enter and be fixed in the shaft groove 492 through the opening of the shaft groove 492, and is in interference fit, so that the hinge shaft 6 is positioned through the shaft groove 492, the hinge shaft 6 is ensured not to be loosened, the synchronous positioning of the corresponding hinge shaft 6 and the hinge frame 2 is realized through the middle hinge cover, and the swinging synchronism of the hinge frame 2 and the middle hinge cover is ensured.

Further, as shown in fig. 23, a flexible circuit board 8 and a flexible heat conductive material 9 are provided inside the mounting passage 46. The flexible circuit board 8 and the flexible heat conduction material 9 can be respectively connected with related components and parts, heat sources and heat-soaking parts at the side of the glasses legs 3 and the side of the glasses frame 1, so that the related hardware, the heat sources and the heat-soaking structures at the side of the glasses legs 3 and the side of the glasses frame 1 can be connected, data of the whole machine can be communicated, and the heat-soaking effect of the whole machine can be achieved. The flexible heat conducting material 9 may be a material with high heat conductivity, such as a flexible graphite sheet, flexible graphene, etc., and can be bent for multiple times.

In addition, the hinge structure comprises at least two hinge frames 2, and accordingly comprises the same number of rotating joints, each rotating joint shares the total swinging amount of the hinge structure through multi-section arrangement, the bending radius of the hinge cover 4 assembly can be increased, and the length expansion amount before and after bending of the bending area between the hinge covers 4 is small. When the hinge structure swings, taking 90-degree swing as an example, the right-end rotating joint of the four rotating joints is fixed, and the other rotating joints swing 30 degrees relative to the adjacent rotating joints at the right end, so that the rotating joint at the leftmost end swings 90 degrees relative to the initial position. By increasing the bending radius, the swing reliability of the flexible circuit board 8 and the flexible heat conductive material 9 inside the mounting passage 46 can be improved, enabling mass-producible levels. Of course, in other embodiments, the hinge frame 2 in the hinge structure may be provided in other numbers, and the larger the number of the joints, the smaller the rotation angle of each joint.

In addition, in order to limit the swing range of each hinge structure and the hinge cover 4 and avoid the influence of the overlarge rotation angle of the single section of the rotation section on the bending angle and the bending radius of the internal flexible circuit board 8 and the flexible heat conduction material 9, a rotation limiting structure can be arranged between the adjacent hinge covers 4. As shown in fig. 24, between adjacent hinge covers 4, an inner positioning surface 44 and an outer positioning surface 42 which are matched with the second hinge cover 4 are arranged on the first hinge cover 4, so that the first hinge cover 4 can be turned inwards relative to the second hinge cover 4 to rotate the inner positioning surface 44 to abut against the second hinge cover 4 at most, and can be turned outwards to rotate the outer positioning surface 42 to abut against the second hinge cover 4 at most, and double limiting is realized by matching the abutting between the movable block 52 and the fixed block 51 as well as between the hinge brackets 2. Alternatively, each hinge cover 4 is rotatable over the same angular range, for example 30 °, or 45 °, with respect to the adjacent hinge cover 4.

Further, as shown in fig. 23, between every two adjacent hinge covers 4, one of the hinge covers is provided with a connecting protrusion 43, the other hinge cover is provided with a connecting groove 41, the connecting groove 41 is rotatably sleeved outside the connecting protrusion 43, the connecting groove 41 can shield the connecting protrusion 43, and each hinge cover 4 and the inner hinge frame 2 thereof rotate synchronously. Through the shielding of the connecting protrusion 43 by the connecting groove 41, the installation channel 46 can be completely shielded all the time at the butt joint of the hinge cover 4 and the hinge cover 4 in the rotating process, so that the components installed in the installation channel 46 are not exposed, and the safety and the attractiveness are ensured.

The hinge structure that this embodiment provided, when being applied to intelligent glasses, the theory of operation: as shown in fig. 12, the left end is connected to the frame 1 and the right end is connected to the temple 3. When not in use, the hinge structure is in a limit inward folding state. The outward turning temple 3, the fixed block 51 and the corresponding movable block 52 act through the inclined plane, so that the movable block 52 moves downwards, the fixed block 51 generates a resetting force in the inward folding direction on the movable block 52, and the resetting force is gradually increased. The damping elastic member 7 also provides a damping force during rotation, improving the use feeling.

In the embodiment, the reset component 5 and the damping elastic part 7 are arranged on the hinge shaft 6, so that the multifunction of the hinge shaft 6 is realized, and the assembly is convenient; the hinge structure is provided with a plurality of sheet metal parts or simple machined parts, a movable block 52, a disc spring, a spring and the like, all parts are simply machined, bent, welded and highly generalized, and the machining and manufacturing cost and difficulty are greatly reduced; the hinge shaft 6 is provided with the damping elastic member 7 and locked by the lock nut 63, and the elastic force of the damping elastic member 7 is adjusted by adjusting the lock nut 63, so that a frictional force is generated when the hinge shaft rotates, and a damping force is provided, so that the hinge structure has a damping effect.

Of course, in other embodiments, the restoring assembly 5 may be configured otherwise, for example, the restoring assembly 5 includes a pressing structure and an elastic member sequentially arranged along a predetermined direction, the pressing structure and the elastic member are respectively connected to two adjacent hinge frames 2, and when the hinge frames 2 are turned outwards, the elastic member is pressed by the pressing structure to deform, so that the hinge frames 2 turned outwards have a tendency to fold inward to provide pressing force towards the head for the temple 3.
