Preferred embodiments of the present disclosure are described in further detail below with reference to the accompanying drawings of the present specification.

The present disclosure provides a pressure maintaining jig for maintaining pressure of an electronic device or a component in the electronic device during a production process. The pressure maintaining jig disclosed by the disclosure not only can maintain pressure for electronic equipment with a smooth surface, but also can maintain pressure for a certain part in the electronic equipment/electronic equipment with an uneven surface, an irregular shape and an arc-shaped surface.

In the present disclosure, the type of the electronic device is not limited. In a specific application of this disclosure pressurize tool for intelligent glasses carry out the pressurize. The intelligent glasses comprise a support used for being worn on the head and a front face mask installed on the support, wherein the front face mask comprises an outer shell and an optical component, a control component and the like in the outer shell. When the intelligent glasses are in a normal wearing state, the front face cover integrally presents an arc surface from left to right, and the position of the front face cover corresponding to the bridge of the nose of a user is the most protruding area of the arc surface. In the following embodiments, the pressure to be maintained is taken as an example of smart glasses.

Referring to fig. 1, fig. 1 is a top view of a pressure maintaining jig according to an embodiment. In one embodiment, the pressure maintaining jig includes a base 10 and a pressure maintaining mechanism 20. The base 10 is used for supporting a to-be-maintained member; the pressure maintaining mechanism 20 comprises a pressing part 21 and a driving component 22 in driving connection with the pressing part 21, the driving component 22 is installed on the base 10, and the driving component 22 is used for driving the pressing part 21 to move so as to press on the surface of the member to be maintained; the pressure maintaining mechanism 20 is provided in plurality, and the pressure maintaining mechanisms 20 are arranged in a distributed manner, so that the pressing members 21 of the pressure maintaining mechanisms 20 collectively maintain pressure on the member to be pressure maintained.

Before pressure maintaining, the front face cover of the intelligent glasses is assembled. According to different assembling sequences, the pressure of the independent front mask can be maintained after the front mask is assembled independently; or the front face mask and the support can be assembled to form the intelligent glasses, and the front face mask part of the intelligent glasses is placed on the base 10 to prepare for pressure maintaining.

The base 10 serves on the one hand for placing the front mask and on the other hand for installing the pressure-maintaining means 20. In this embodiment, the use orientation of the pressure holding jig is not limited, and the pressing member 21 may hold the pressure of the front cover from the bottom to the top, or may hold the pressure of the front cover in the horizontal direction. In one example, the front face mask is placed on top of the base 10, and the pressing member 21 presses down on the surface of the front face mask from above, thereby realizing pressure holding.

Referring to fig. 2, fig. 2 is another perspective view of the pressure maintaining jig shown in fig. 1. In a specific example, the top of the base 10 is provided with a receiving groove 102, and the receiving groove 102 is used for receiving the pressure to be maintained; the shape of the accommodating groove 102 is matched with that of the pressure maintaining piece, and at least the bottom wall of the accommodating groove 102 is attached to the surface of the front face mask, so that the pressure maintaining effect is improved.

Specifically, the state when using intelligent glasses normally to wear is the position reference, and the one side that leading face guard faced user's face is the inboard, and the one side that deviates from user's face is the outside. The bottom wall of the containing groove 102 on the base 10 is matched with the shape and radian of the outer side surface of the front mask. The pressure maintaining mechanisms 20 are pressed on the inner side surface of the front face mask from top to bottom so as not to affect the outer side surface of the front face mask.

The depth of the receiving groove 102 may be set according to the thickness of the front mask. In an embodiment, the depth of the receiving groove 102 may be adjustable. Illustratively, the receiving groove 102 may be formed by a through hole formed in the base 10 and a chassis disposed in the through hole and capable of moving up and down. Therefore, the purpose of adjusting the depth of the accommodating groove 102 is achieved by adjusting the position of the chassis. From this can realize that the base adaptation is in the same kind of structure, but the leading face guard of thickness difference is favorable to improving the application flexibility of this embodiment pressurize tool.

In order to improve the effective pressure maintaining of each part of the front face mask. In an embodiment, the pressure maintaining mechanisms 20 are located outside the containing groove 102 and are correspondingly disposed along an extending direction of an edge of the containing groove 102. The plurality of pressure holding mechanisms 20 are not necessarily uniformly provided, and the positions of the pressure holding mechanisms 20 may be adjusted according to the positions of the front face mask where pressure is to be held and the regions where stress is likely to concentrate during the use of the smart glasses.

The dimensions of the respective holding pressure mechanisms 20 may be the same or different, and the pressing forces generated by the respective holding pressure mechanisms 20 may be the same or different. Therefore, adaptive pressing of different parts on the front face mask can be realized, and the pressure maintaining effect is improved.

As mentioned above, the pressure maintaining mechanism 20 includes the pressing member 21, and the driving component 22 for driving the pressing member 21 to move so as to press on the front face cover surface. In one example, the pressure holding mechanism 20 has a closing member 21, and a driving member 22. In another example, the pressure holding mechanism 20 includes a plurality of the pressing members 21, and the plurality of the pressing members 21 are in driving connection with the driving component 22 of the pressure holding mechanism 20. Namely, one driving component 22 drives a plurality of pressing components 21 to move simultaneously, so that the plurality of pressing components 21 are pressed on the surface of the front face mask together to realize pressure maintaining.

The driving assembly 22 may be in the form of an electrical device as a driving source, or may be in the form of a purely mechanical structure. In one example, the driving assembly 22 includes a motor and a linkage structure, the motor drives the linkage structure to move, so as to drive the pressing member 21 to move downwards to press on the front mask surface. Of course, the electric motor can also be replaced by a cylinder here.

Please refer to fig. 3 and 4. FIG. 3 is a longitudinal sectional view of the pressure maintaining jig of FIG. 2; fig. 4 is another view of the pressure maintaining jig shown in fig. 1. In another example, the driving assembly 22 includes a linkage and an elastic member 224 movably connected to the linkage; the linkage piece is fixedly connected with the pressing piece 21 so as to drive the pressing piece 21 to move; when the pressure to be maintained is to be maintained, the elastic member 224 provides a force along the pressing direction to the linkage member, so that the linkage member drives the pressing member 21 to move along the pressing direction, so as to press the pressure to be maintained.

In this example, the driving component 22 is a purely mechanical structure that enables driving of the press-fitting piece 21. The elastic member 224 may be a spring, a leaf spring, or the like. According to the relative position of the elastic member 224 and the linkage member, there are two cases, one is that, when the pressure to be maintained is to be maintained, the elastic member 224 is in a compressed or contracted state, so as to provide a force in the pressing direction to the linkage member; alternatively, when the pressure to be maintained is to be maintained, the elastic member 224 is in a stretched or expanded state, so as to provide a force in the pressing direction to the linkage member.

The elastic force of the elastic member 224 in the compressed or stretched state is used as a power source for driving the interlocking member, so that the structural complexity of the pressure holding mechanism 20 can be simplified, and the control cost can be saved.

In one embodiment, the linkage includes a first linkage rod 221, a stopper 222; the base 10 is internally provided with a mounting cavity 101; the first end of the first linkage rod 221 is fixedly connected with the pressing piece 21, and the second end of the first linkage rod 221 extends into the installation cavity 101 from the top of the base 10; the stopper 222 and the elastic member 224 are both located in the installation cavity 101, the stopper 222 is fixedly connected with the second end of the first linkage rod 221, one end of the elastic member 224 abuts against the stopper 222, and the other end abuts against the top wall of the installation cavity 101; when the pressure to be maintained is to be maintained, the elastic member 224 is in a compressed state to provide a force in the pressing direction to the first linkage rod 221 through the stopper 222.

In this embodiment, after the front face mask is placed in the receiving groove 102 of the base 10, the top surface of the front face mask protrudes from the top surface of the base 10, so as to push the pressing member 21 upward, and the pressing member 21 moves upward to drive the first connecting rod 221 to move upward, so that the second end of the first connecting rod 221 drives the stopper 222 to move upward together. Since the elastic member 224 is abutted against the stopper 222 and the top wall of the receiving cavity 102, the spring is gradually compressed along with the upward movement of the stopper 222. The compressed spring further generates an opposite acting force to the stopper 222, and the direction of the opposite acting force is downward, so that the stopper 222 receives a downward acting force together with the first linkage rod 221, and the pressing member 21 connected to the first linkage rod 221 also receives a downward acting force, thereby generating a pressing force for pressing the front face cover.

It can be seen that, in the embodiment, due to the placement position of the front mask in the receiving groove 102, the pressing member 21 is triggered to generate an upward displacement, so that the elastic member 224 is compressed, and the compressed elastic member 224 finally feeds back a downward pressing force to the pressing member 21. Therefore, this embodiment scheme need not to utilize external energy, and overall structure is exquisite compact, has simplified the design that can keep the pressure to the opposite sex product pressurize tool greatly, has saved the cost.

It should be understood that, based on the inventive concept of the present embodiment, the position of the elastic member 224 may also be adjusted, so that the elastic member 224 is located at the lower side of the stopper 222 (or directly located at the lower side of the first linkage rod 221, in which case, the stopper 222 is not necessarily configured), so as to provide a downward pressing force to the linkage member and the pressing member 21 when the elastic member 224 is stretched, thereby implementing a pressure maintaining action.

Further, in an embodiment, the stopper 222 includes a body 2221 and a mounting portion 2222 protruding from the body 2221; the mounting portion 2222 extends into the second end of the first linkage rod 221, so as to be in threaded connection with the first linkage rod 221, and the mounting portion 2222 is rotated so as to adjust the distance between the stopper 222 and the top wall of the mounting cavity 101. In one example, the elastic member 224 is a spring, and the spring is sleeved outside the mounting portion 2222 of the stopper 222 and the second end of the first linkage rod 221.

In one example, the body 2221 and the mounting portion 2222 of the stop 222 may be an integral structure, and the mounting portion 2222 has a cylindrical structure and is provided with an external thread along an outer surface of the mounting portion 2222. A channel for the mounting portion 2222 to extend into is formed at the second end of the corresponding first linkage rod 221, and an internal thread is formed on the wall surface of the channel. Therefore, the mounting portion 2222 and the first linkage rod 221 may be fixedly coupled not only by engagement of the external and internal threads.

In addition, the mounting portion 2222 and the first linkage rod 221 can further adjust the distance between the body 2221 of the stopper 222 and the second end of the first linkage rod 221 by adjusting the engagement length of the external thread and the internal thread, and further can adjust the distance from the body 2221 of the stopper 222 to the top wall of the mounting cavity 101, thereby achieving the purpose of adjusting the initial state of the spring.

For example, if it is required to provide a larger holding force to the front face cover, the stopper 222 can be rotated to reduce the distance between the body 2221 of the stopper 222 and the second end of the first linkage rod 221, so as to reduce the distance from the body 2221 of the stopper 222 to the top wall of the mounting cavity 101, so that the spring has a larger compression amount, thereby generating a larger elastic force.

Similarly, if it is not necessary to provide a large holding force for the front face cover, the stopper 222 may be rotated to increase the distance between the body 2221 of the stopper 222 and the second end of the first linkage rod 221, so as to increase the distance from the body 2221 of the stopper 222 to the top wall of the mounting cavity 101, so that the spring is in an initial state without compression or an initial state with a small amount of compression, so as to generate an elastic force with a suitable magnitude.

It should be appreciated that the mounting portion 2222 may be further channeled with internal threads disposed on the channel wall and external threads disposed on the outer wall surface of the second end of the first linkage rod 221 to provide a connection between the mounting portion 2222 and the second end of the first linkage rod 221.

In the above embodiment, the mounting cavity 101 may be opened from the bottom of the base 10 and extend toward the top of the base 10. Therefore, when the pressure holding mechanism 20 is assembled to the base 10, the elastic member 224 and the stopper 222 are placed in the mounting chamber 101 from the bottom of the mounting chamber 101, and the stopper 222 is screwed to the first linkage rod 221 by rotation. Similarly, the stopper 222 may be rotated from the bottom of the mounting chamber 101 to detach the first linkage rod 221 from the stopper 222.

The connecting structure of the first linkage rod 221 and the stopper 222 and the installation cavity 101 in this embodiment are arranged, so that the first linkage rod 221 and the stopper 222 can be conveniently connected and detached through the installation cavity 101, the pressurizer can be conveniently installed on the base 10, and the pressurizer can be conveniently removed from the base 10. Therefore, the flexibility that the pressure maintaining device position set up has been realized to this embodiment to make can be according to the concrete structure, the shape of treating the pressure maintaining piece, and the quantity that has corresponding set up the pressurizer to and the position of pressurizer, when having realized carrying out the pressurize to opposite sex product, improved the pressurize effect.

Further, in an embodiment, the linkage further includes a connecting rod 223, and the pressing member 21 is rod-shaped; one end of the connecting rod 223 is fixedly connected to one end of the pressing member 21, and the other end of the connecting rod 223 is fixedly connected to the first end of the first linkage rod 221.

In one example, the first linkage rod 221 and the pressing member 21 extend substantially in the vertical direction, and the linkage rod 223 extends substantially in the horizontal direction. The first linkage rod 221 and the linkage rod 223 may be detachably connected, for example, by a screw; specifically, threaded holes are formed in both the first linkage rod 221 and the connecting rod 223, and screws sequentially penetrate through the threaded holes in the first linkage rod 221 and the connecting rod 223, so that the first linkage rod 221 and the connecting rod 223 are fixedly connected. The engaging member 21 and the connecting rod 223 may be detachably connected, for example, by screws. Thereby, the assembling flexibility of the pressure holding structure can be achieved.

In this embodiment, the pressing member 21 with a suitable length may be selected according to the specific structure, shape, or thickness of the member to be held, and then the connecting rod 223 with a suitable length may be selected according to the position to be pressed on the member to be held and the position of the mounting hole reserved on the base 10, where the mounting hole is opened at the top of the base 10 for the first connecting rod 221 to extend into the mounting cavity 101. Thus, the present embodiment achieves structural flexibility of the pressure holding mechanism 20, and can be used for holding pressure for pressure-retaining members of various structures and shapes.

When one pressure holding mechanism 20 includes a plurality of the engaging members 21, a plurality of connecting rods 223 may be correspondingly provided, and the plurality of connecting rods 223 are fixedly connected to the first connecting rod 223 in common. The plurality of connecting rods 223 are connected to the plurality of press-fitting members 21 in a one-to-one correspondence. The purpose of simultaneously driving the movement of a plurality of pressing pieces 21 by one driving component 22 is achieved.

In one embodiment, the pressing element 21 includes a second linkage 211 and a pressing head 212 detachably connected to one end of the second linkage 211; the other end of the second linkage 211 is fixedly connected to the driving component 22.

The second linking rod 211 extends substantially along the vertical direction and is substantially parallel to the first linking rod 221. The second linkage 211 is detachably connected to the pressure head 212, so that the pressure head 212 or the second linkage 211 can be flexibly combined, and the pressure maintaining effect is improved.

The ram 212 may be made of a material having elasticity, such as silicone rubber or TPU (Thermoplastic polyurethane elastomers), and the like. In this manner, the indenter 212 may reduce scratching of the front mask surface when the front mask contacts.

In addition, in the present embodiment, in order to improve the pressing effect on the front face mask, the pressing head 212 is configured to press the end surface of the to-be-maintained member to adapt to the surface inclination and/or shape of the pressed portion of the to-be-maintained member. For example, the front face mask surface is substantially a cambered surface, so the surface of the pressed part is embodied as an inclined surface, and the end surface of the pressure head 212 is set to be a shape with an inclination adapted to the inclination of the surface of the pressed part, so as to increase the contact area between the pressure head 212 and the front face mask surface, so that the force on the pressure head 212 can be effectively transmitted to the front face mask, and the pressure maintaining effect is improved.

Based on all the above embodiments, the overall process of pressure maintaining of the front mask is described with the pressure maintaining jig.

Before pressure maintaining, the front face mask is subjected to glue dispensing operation, and specifically, the front face mask comprises a face frame and a transparent lens which needs to be installed on the face frame. Firstly, glue is dispensed at the edge of the face frame, and then the rear transparent lens is arranged on the face frame. And finally, mounting the assembled front face cover on the whole intelligent glasses. In order to connect and fasten the transparent lens and the face frame, the entire assembled front face mask needs to be subjected to pressure maintaining.

The first linkage rod 221 is rotated by a certain angle along the horizontal direction to drive the pressing member 21 to move horizontally, so as to avoid the whole intelligent glasses. And then can install the intelligent glasses complete machine on the base 10 of pressurize tool, make leading face guard just in time be located the mounting groove of base 10, the inboard of leading face guard up this moment.

At this time, the first link rod 221 is pulled upward and the first link rod 221 is horizontally rotated so that the pressure head 212 of the press-fitting member 21 contacts the surface of the front cover. Because the front face mask has a certain thickness, the front face mask supports the pressing piece 21, so that the whole pressing piece 21 is in a lifted state, and further the first linkage rod 221 and the stopper 222 linked with the pressing piece 21 are also in a lifted state, therefore, the distance between the stopper 222 and the top wall of the installation cavity 101 is reduced, and the spring is in a compressed state. The spring in the compressed state has a downward reaction force on the stopper 222, so that the pressing member 21 has a downward pressure through the conduction of the first connecting rod 221 and the connecting rod 223, so that the pressing head 212 is tightly pressed against the surface of the front mask.

The pressing members 21 of the plurality of pressing mechanisms are thus pressed together against the surface of the front face mask to maintain the pressure of the front face mask.

The technical scheme of the disclosure is different from the traditional mode of pressing the upper die and the lower die so as to maintain the pressure of the to-be-maintained piece, and adopts the form of arranging the base 10 and the plurality of pressure maintaining mechanisms 20 on the base 10. Therefore, the number of the pressure maintaining mechanisms 20 and the positions on the base 10 can be set according to the shape and the structure of the pressure maintaining member, so that the pressure maintaining of the special-shaped product is realized. For traditional pressurize tool to this disclosed pressurize tool need not to design and treats the structure that the pressurize piece matches completely, and need not to wrap up completely and treat the pressurize piece, consequently the effectual structural complexity who reduces the pressurize tool of this disclosed scheme, and the effectual volume that reduces the pressurize tool.

The pressure maintaining jig is not limited by the structure and the size of the to-be-maintained piece, and can maintain pressure of a special-shaped product; and the position of the pressure maintaining mechanism 20 on the base 10 can be flexibly adjusted and/or the bases 10 in different shapes can be replaced according to the different specific structures and shapes of the parts to be pressure maintained, so that the adaptability of the pressure maintaining jig and various parts to be pressure maintained is realized. Therefore, the pressure maintaining jig disclosed by the embodiment of the disclosure has higher application flexibility.
