[0003] In existing smart glasses on the market, the frames and temples may become misaligned or have large gaps when rotated and unfolded. With long-term use, the misalignment and gaps between the frames and temples can cause the temples to shift or make abnormal noises, thus affecting the overall usability of the smart glasses and causing great inconvenience. Summary of the Invention
[0004] The purpose of this invention is to provide a hinge for smart glasses with an ingenious structure that can greatly reduce misalignment or angular gaps between the frame and temples, while also allowing for the expansion of the temples, making it convenient and practical.
[0005] The technical solution to achieve the purpose of this utility model is as follows: This utility model has a first mounting block for mounting a mirror frame and a second mounting block for mounting a temple; the first and second mounting blocks have the same cross-section, and a rotating assembly is provided between the first and second mounting blocks. The rotating assembly includes a fixed bracket installed in the first mounting block, a rotating bracket installed in the second mounting block, and an outwardly expanding bracket disposed between the fixed bracket and the rotating bracket. The outwardly expanding bracket includes a bracket body, a support portion disposed opposite to and integrally formed with the bracket body, an outwardly expanding arc-shaped portion integrally formed with the bracket body, and bottom connecting portions disposed opposite to both sides of the outwardly expanding arc-shaped portion. The rotating bracket is rotatably connected between the oppositely arranged support portions. The bracket body has a limiting surface, and the rotating bracket presses against the limiting surface after rotation. The fixed bracket has a first fixing block and a second fixing block integrally formed with the fixed bracket. A fixing slot is formed between the first fixing block and the second fixing block, into which the outwardly expanding arc-shaped part can be inserted. The second fixing block has an inner arc-shaped surface corresponding to the outwardly expanding arc-shaped part. After the outwardly expanding arc-shaped part is inserted into the fixing slot, it forms a surface contact with the inner arc-shaped surface on the second fixing block. The bottom surface of each bottom connecting part is pressed against the upper end surface of the fixing bracket. A bottom bolt is installed on the bottom surface of each bottom connecting part. The fixing bracket has a bottom through hole through which the bottom bolt can pass. The inner diameter of each bottom through hole is larger than the diameter of the bottom bolt. A return spring is sleeved on each bottom bolt. The two ends of the return spring act on the bottom of the bottom bolt and the bottom of the fixing bracket, respectively. The second mounting block is rotatably connected by the cooperation of the rotating bracket and the support part. The outwardly expanding bracket drives the second mounting block to expand outward by the pressure of the rotating bracket and the limiting surface, and the sliding cooperation of the outwardly expanding arc-shaped part and the inner arc-shaped surface. Under the continuous force of each return spring, the second mounting block is driven to return to its original position.
[0006] Furthermore, the first mounting block is provided with a first mounting groove, the fixed bracket is fixedly installed in the first mounting groove, and each bottom bolt is located between the fixed bracket and the bottom of the first mounting groove. The second mounting block is provided with a second mounting groove, the rotating bracket is fixed in the second mounting groove, and each bottom connecting part has an arc-shaped sliding surface at the end away from the outward expansion bracket. Each arc-shaped sliding surface forms a sliding gap with the upper end surface of the fixed bracket and the side wall of the first mounting groove.
[0007] Furthermore, each support is equipped with a positioning block, and each positioning block is provided with a rotating shaft. The positioning blocks are arranged opposite each other, and the rotating shafts on each positioning block are also arranged opposite each other. The positioning block includes a first connecting block and a second connecting block. The support is provided with a side groove adapted to the first connecting block and a mounting through hole adapted to the second connecting block. The positioning block is fixedly installed on the support through the insertion and cooperation of the first connecting block and the side groove, and the insertion and cooperation of the second connecting block and the mounting through hole. The rotating bracket is provided with rotating holes adapted to each rotating shaft. The rotating bracket is rotatably connected between the support parts through the cooperation of each rotating shaft and the rotating hole.
[0008] Furthermore, the bracket body is provided with a positioning slot, and the fixed bracket is provided with a first fixing block that is adapted to the positioning slot. After the first fixing block is connected to the fixed slot in the outwardly expanding arc-shaped part, it is inserted and engaged with the positioning slot.
[0009] Furthermore, the second mounting block is provided with arc-shaped sliding plates that are oppositely arranged and integrally formed with the second mounting block. Each arc-shaped sliding plate is located on the end face of the second mounting block near the second mounting groove. The first mounting block is provided with arc-shaped sliding grooves that are oppositely arranged and integrally formed with the first mounting block. Each arc-shaped sliding groove is located on the end face of the first mounting block near the first mounting groove. When the first mounting block and the second mounting block are rotatably connected, each arc-shaped sliding plate slides in the corresponding arc-shaped sliding groove. Each arc-shaped sliding plate and each arc-shaped sliding groove are coaxially arranged with the rotating shaft.
[0010] Furthermore, the second mounting block is also provided with a third mounting groove for mounting the temple.
[0011] This utility model has the following positive effects: (1) By setting the first mounting block and the second mounting block to have the same cross section, and setting a rotating component between the first mounting block and the second mounting block, the rotating bracket drives the second mounting block to rotate through the rotating connection with the outward expansion bracket. The rotation of the second mounting block drives the included angle between the frame and the temple to rotate from 0 degrees to 90 degrees. The outward expansion bracket drives the second mounting block to expand outward through the pressing of the rotating bracket and the limiting surface, and the sliding cooperation between the outward expansion arc part and the inner arc surface. The included angle between the frame and the temple rotates outward from the included angle of 90 degrees to 97.5 degrees, and under the continuous force of each return spring, it drives the second mounting block to expand outward. The second mounting block is reset until the angle between the frame and the temple is 90 degrees, effectively ensuring the automatic reset of the temple after expansion. At the same time, the rotational cooperation of the rotating bracket and expansion bracket of the first and second mounting blocks, as well as the identical cross-section of the first and second mounting blocks, can greatly reduce the misalignment of the first and second mounting blocks after rotation and expansion. It can also greatly reduce the gap at the expansion angle between the two, effectively solving the problem of temple shifting or abnormal noise caused by misalignment between the temple and frame or excessive gap at the expansion angle in the prior art. The structure is ingenious, convenient and practical.
[0012] (2) This utility model provides arc-shaped sliding surfaces on each bottom connection part, and the arc-shaped sliding surfaces form a sliding gap with the upper end surface of the fixed bracket and the first mounting groove, thereby avoiding jamming of the expansion bracket during rotation, ensuring smooth expansion of the expansion bracket, which is convenient and efficient.
[0013] (3) This utility model sets positioning blocks on each support part, and sets the positioning blocks as first connecting blocks and second connecting blocks. The first connecting block is inserted into the side groove and the second connecting block is connected to the mounting through hole, thereby ensuring the stability of each positioning block and the rotating shaft on the positioning block during the rotation process, and further ensuring the stability of the rotating bracket during the rotation process, which is efficient and convenient.
[0014] (4) This utility model provides a positioning slot on the bracket body and a first fixing block on the fixed bracket. The cooperation between the first fixing block and the positioning slot effectively ensures the stability of the bracket body after it is connected to the fixed bracket, making it stable and practical.

[0036] The working principle of this utility model is as follows: During use, the frame is mounted on the first mounting block 1, and the temples are mounted on the second mounting block 2. At this time, the included angle between the frame and the temples is 0 degrees. The cross-sections of the first mounting block 1 and the second mounting block 2 are made identical. An arc surface coaxial with the rotating shaft 363 is provided on the outward expansion bracket 32 and the second fixing block 332. After rotation, the misalignment of the first mounting block 1 and the second mounting block 2 is greatly reduced, as is the gap at the outward expansion angle during rotation. This effectively ensures the coplanarity between the frame and the temples, effectively solving the problem of abnormal noise or displacement caused by misalignment between the frame and the temples in the prior art, ensuring the normal use of the smart glasses. Furthermore, the second mounting block 2 rotates with the first mounting block 1 through the rotating component 3. During operation, the second mounting block 2 is rotatably connected through the cooperation of the rotating bracket 31 and the support part 322. The outward expansion bracket 32 drives the second mounting block 2 to expand outward through the pressing of the rotating bracket 31 and the limiting surface 326, and the sliding cooperation of the outward expansion arc part 324 and the inner arc surface 333. Under the continuous force of each return spring 35, the second mounting block 2 is driven to return to its original position. During the rotation of the second mounting block 2, after the rotating bracket 31 and the limiting surface 326 are pressed together, a 90-degree angle is formed between the temple and the frame. During the rotation, the sliding gap effectively avoids the situation of the outward expansion bracket 32 getting stuck during the rotation. The temple can expand to a maximum of 97.5 degrees and is returned to its original position through the continuous force of the return spring 35. At the same time, during the rotation, the cooperation of each arc-shaped sliding plate 21 and each arc-shaped sliding groove 11 ensures the smooth connection between the first mounting block 1 and the second mounting block 2. The structure is ingenious, efficient and convenient.
