Description

Technical Field

[0001] The present application relates to the field of smart glasses, and in particular to a temple hinge module and smart glasses. Background Art

[0002] The temples and frames of smart glasses (such as AR glasses) are generally connected by temple hinge modules, which can make the temples have folded and opened states relative to the frame. The temples of some current smart glasses have a small opening angle, which is not friendly to wearers with large heads. Gradually, some manufacturers have also discovered this problem, and have launched some temple structures with temples that can be opened at multiple angles. The temples have folded positions, open positions, and everted positions. However, the hinge module structures on these smart glasses generally have more accessories, are heavier, and are larger in size. Summary of the invention

[0003] In order to reduce the number of structural accessories and the overall volume while achieving multi-angle opening of the temples, the present application provides a temple hinge module and smart glasses.

[0004] In the first aspect, the present application provides a temple hinge module adopting the following technical solution: A temple hinge module, comprising: The moving tube has a first connection portion for connecting with the temples on its wall, and a plurality of limiting grooves for respectively fixing the temples at 90 degrees and 180 degrees on its bottom, wherein the groove walls on both sides of the limiting grooves are guiding inclined surfaces; The fixing member comprises a supporting shaft passing through the bottom of the tube, a matching member sleeved on the supporting shaft and located on the moving tube, and an elastic member, wherein the supporting shaft is provided with a second connecting portion for connecting with the eyeglass frame, the supporting shaft and the matching member are configured to be unable to rotate relative to each other, the matching member has a first protrusion abutting against the limiting groove to achieve limiting, and the moving tube is used to move the first protrusion to the guiding inclined surface under the action of an external force, so that the temple is everted, and at this time, the elastic member is compressed to limit the displacement of the matching member; The limiting member comprises a protruding bone position and a limiting groove, wherein the protruding bone position is used to abut against the end of the limiting groove under the cooperation of external force to limit the eversion angle of the temple.

[0005] By adopting the above technical solution, assuming that the temple is in a folded state initially, the first protrusion of the matching piece abuts against one of the limiting grooves for limiting the temple to be in a folded position (the angle between the temple and the frame is 90 degrees); in the initial position, the first end of the protruding bone abuts against the first end of the limiting groove; when the temple is opened, an external force is applied to the temple to rotate the moving tube, and with the help of the guiding effect of the guiding inclined surface, the first protrusion continuously moves from the limiting groove that makes the temple stationary at 90 degrees to the other limiting groove that makes the temple stationary at 180 degrees, and at this time, the protruding bone and the limiting groove slide relative to each other, and when the moving tube rotates When the first protrusion of the matching piece moves in the spaced limiting grooves, the matching piece jumps up and down along the supporting shaft; when the temple needs to be everted, the external force is continuously applied to the temple, and the first protrusion gradually moves from the bottom of the limiting groove that makes the temple stationary at the 180-degree position by utilizing the guiding effect of the guiding inclined surface, until the second end of the protruding bone position abuts against the second end of the limiting groove, and the temple cannot continue to be opened outwards. At this time, the first protrusion abuts against the guiding inclined surface, and the elastic piece is in a compressed state. When the external force applied to the temple is released, the first protrusion returns to the limiting groove that makes the temple stop at the 180-degree position under the action of the restoring force of the elastic piece; The present application uses a matching piece, with the help of the guiding inclined surface of the limiting groove, to realize the opening and eversion of the temple under the action of external force, and to achieve the state of the temple being locked at the 90-degree position and the 180-degree position when no external force is applied. The core components only require matching pieces, moving tubes and elastic pieces. There are fewer accessories and a simple structure, which can achieve the effect of reducing the overall volume and weight of the module.

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-6 This application is described in further detail.

[0031] The present application embodiment discloses a temple hinge module. Figure 1 and Figure 2 The temple hinge module includes a moving cylinder 1, a fixing member 2 and a limiting member 3. The moving cylinder 1 is used to connect with the temple 01, and the fixing member 2 is used to connect with the frame 02. By setting the temple hinge module of the present application, the temple 01 has a folding position (i.e., a position where the angle between the temple 01 and the frame 02 is 90 degrees), an open position (i.e., a position where the angle between the temple 01 and the frame 02 is 180 degrees) and an eversion position (i.e., a position where the angle between the temple 01 and the frame 02 is greater than 180 degrees). The limiting member 3 is used to limit the eversion angle of the temple 01.

[0032] Reference Figure 1-Figure 4 The wall of the moving tube 1 is provided with a first connecting portion 11 for connecting with the temple 01. The bottom of the tube is provided with a plurality of limiting grooves 12 for respectively fixing the temple 01 at 90 degrees and 180 degrees, and each limiting groove 12 is arranged with a circle around the axial direction of the moving tube 1. Each limiting groove 12 has a lowest point, and the groove walls on both sides of the limiting groove 12 are guiding inclined surfaces, and a limiting protrusion 13 is formed between two adjacent limiting grooves 12. In one embodiment of the present application, the limiting protrusion 13 is conical, and the limiting groove 12 is a V-shaped groove.

[0033] Reference Figure 3-Figure 5 The fixing member 2 includes a support shaft 21 passing through the bottom of the cylinder, a matching member 22 sleeved on the support shaft 21 and located inside the moving cylinder 1, and an elastic member 23. The matching member 22 is configured not to rotate relative to the support shaft 21, but can slide up and down along the support shaft 21 under the restriction of the elastic member 23. Specifically, the two sides of the support shaft 21 of the present application are milled flat into planes, and a square hole matching the support shaft 21 is machined in the center of the matching member 22.

[0034] One end of the elastic member 23 is fixed on the support shaft 21, and the other end is in contact with the fitting member 22, so as to clamp the fitting member 22 in position on the support shaft 21, and allow it to move up and down along the support shaft 21 within a certain range. The elastic member 23 can use any structure with elastic restoring force, such as a compression spring, a torsion spring, etc., and the present application takes the elastic member 23 as an example for explanation. The compression spring of the present application is locked with a fastening snap ring 26, and an arc-shaped retaining groove 211 is provided on the side wall of the support shaft 21, and the fastening snap ring 26 is embedded in the retaining groove 211 to limit the position of the compression spring.

[0035] Reference Figure 3-Figure 5 , the matching piece 22 has a first protrusion 221 for abutting against the limiting groove 12 to achieve limiting. When the first protrusion 221 is stuck at the lowest point of the limiting groove 12, the position of the temple 01 is fixed. When an external force is applied to rotate the temple 01, the moving cylinder 1 rotates, and under the guiding action of the guiding slope, the first protrusion 221 moves along the guiding slope and is stuck at the lowest point of another limiting groove 12, so as to respectively achieve the fixation of the temple 01 at different positions. Continue to apply an outward opening force to the temple 01, the moving cylinder 1 continues to rotate, and under the drive of the guiding slope, the first protrusion 221 abuts against the guiding slope, the elastic piece 23 is compressed, and the temple 01 is turned outward. And under the restoring force of the elastic piece 23, an inward force will be applied to the temple 01 to ensure the stability when the user wears it. When the external force applied to the temple 01 is released, under the action of the restoring force of the elastic member 23, the first protrusion 221 returns to the limiting groove 12 which stops the temple 01 at the 180 degree position.

[0036] Reference Figure 1 and Figure 6 Preferably, the mouth of the moving tube 1 is configured so that when the user wears the glasses normally, the mouth of the moving tube 1 is facing upward, and the matching piece 22 and the elastic piece 23 are arranged in sequence from bottom to top along the support shaft 21. When the external force applied to the temple 01 is released, the matching piece 22 can abut against the lowest point of the limiting groove 12 under the action of its own gravity, the guiding effect of the guiding slope, and the restoring force of the elastic piece 23, that is, it returns to the position where the temple 01 is fixed at 180 degrees.

[0037] Reference Figure 3-Figure 5In order to prevent the temple 01 from being over-opened, the eversion angle of the temple 01 under the action of external force is limited by the limiter 3. The limiter 3 includes a raised bone position 31 arranged on the bottom plate 25 / moving tube 1, and a limited groove 32 is arranged on the back side of the moving tube 1 / bottom plate 25. The raised bone position 31 is used to slide in the limited groove 32. And when the raised bone position 31 abuts against the end of the limited groove 32, the temple 01 cannot continue to open outward. Specifically, it is assumed that the temple 01 is in a folded state at the beginning, and the first end of the raised bone position 31 abuts against the first end of the limited groove 32. As the temple 01 is opened under the action of external force, the raised bone position 31 and the limited groove 32 slide relative to each other. When the temple 01 is opened to the 180-degree position, the second end of the raised bone position 31 is close to the second end of the limited groove 32. When the temple 01 is opened to the eversion angle, the second end of the protruding bone position 31 abuts against the second end of the limiting groove 32, and the temple 01 cannot continue to open outward. At this time, the first protrusion 221 abuts against the guiding inclined surface.

[0038] The protruding bone position 31 and the limiting groove 32 are both arc-shaped, and are designed according to the angle between the two limiting grooves 12, the curvature of the protruding bone position 31, and the preset eversion angle of the temple 01. The embodiment of the present application is described by taking the eversion angle α of the temple 01 as 5-15°, and four limiting grooves 12 are arranged circumferentially around the bottom of the tube as an example. At this time, the angle between two adjacent limiting grooves 12 is 90 degrees, that is, it is only necessary to rotate the temple 01 so that the first protrusion 221 is locked from the lowest point of one limiting groove 12 to the lowest point of another adjacent limiting groove 12. Assuming that the curvature of the protruding bone position 31 is β, the curvature θ of the limiting groove 32 is 90 degrees + α + β.

[0039] To ensure the best wearing effect, the eversion angle α of the temple 01 is 13°.

[0040] Reference Figure 3-Figure 5 In order to facilitate the connection between the support shaft 21 and the frame 02, the end of the support shaft 21 is located outside the moving tube 1, and a bottom plate 25 is provided at this end, and a second connecting portion 24 for connecting with the frame 02 is provided on the bottom plate 25. In order to facilitate the arrangement of the limiting member 3, a protruding bone position 31 is provided on the side of the bottom plate 25 facing the moving tube 1, and a limiting groove 32 is provided on the side of the tube bottom away from the first groove. In this way, the eversion position of the temple 01 can be limited without the need to separately set up other components, thereby reducing the overall volume of the temple hinge module.

[0041] Reference Figure 6In order to facilitate the connection between the moving tube 1 and the temple 01, openings 14 communicating with the internal space are provided on both sides of the tube wall of the moving tube 1, so that the moving tube 1 is divided into two independent arc-shaped enclosure panels, and a first connection portion 11 for connecting with the outer shell of the temple 01 is formed by horizontally extending outward on one side of the enclosure panel, and the first connection portion 11 is fixed to the outer shell of the temple 01 using screws 03. Furthermore, the flexible circuit board 04 is arranged in the space inside the moving tube 1 and passes through the openings 14 on both sides to play the role of hiding and protecting the flexible circuit board 04.

[0042] Reference Figure 3-Figure 5 In order to reduce the friction damage of the temple hinge module of the present application, a friction gasket 4 is arranged between the bottom plate 25 and the bottom of the moving tube 1. A first oil storage groove 5 is provided on the side of the bottom plate 25 facing the support shaft 21, and a second oil storage groove 6 is provided on the side of the bottom of the moving tube 1 facing the bottom plate 25. The first oil storage groove 5 and the second oil storage groove 6 have the function of storing oil, which can effectively reduce the friction between the moving tube 1 and the fixing member 2, so that the service life of the temple hinge module is greatly increased. Furthermore, a fastening gasket 7 is provided between the elastic member 23 and the fastening clamp 26 to avoid wear on the elastic member 23.

[0043] The implementation principle of a temple hinge module of the embodiment of the present application is as follows: assuming that the temple 01 is in a folded state at the beginning, the first protrusion 221 of the matching piece 22 abuts against one of the limiting grooves 12 used to limit the temple 01 to be in the folded position. The first end of the protruding bone position 31 abuts against the first end of the limiting groove 32. When the temple 01 is opened, an external force is applied to the temple 01 to rotate the moving cylinder 1, and with the help of the guiding effect of the guiding inclined surface, the first protrusion 221 moves from the limiting groove 12 to another limiting groove 12 adjacent to it. At this time, the protruding bone position 31 and the limiting groove 32 slide relative to each other, and when the moving cylinder 1 rotates to make the first protrusion 221 of the matching piece 22 move in the spaced limiting grooves 12, the matching piece 22 jumps up and down along the support shaft 21. When the temple 01 needs to be everted, an external force is continuously applied to the temple 01. With the guiding effect of the guiding slope, the first protrusion 221 gradually moves from the bottom of the limiting groove 12 which makes the temple 01 stop at the 180-degree position, until the second end of the protruding bone position 31 abuts against the second end of the limiting groove 32, and the temple 01 cannot continue to open outward. At this time, the first protrusion 221 abuts against the guiding slope, and the elastic member 23 is in a compressed state, applying an inward tightening force to the temple 01 to ensure the stability of wearing. When the external force applied to the temple 01 is released, under the action of the restoring force of the elastic member 23, the first protrusion 221 returns to the limiting groove 12 which makes the temple 01 stop at the 180-degree position.

[0044] The present application also discloses a pair of smart glasses, referring to Figure 1The smart glasses include the temple hinge module in the above embodiment, and also include a frame 02 and a temple 01 , wherein the temple hinge module is connected to the temple 01 and the frame 02 via screws 03 .

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
