Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0030] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture.

[0031] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0032] Common types of glasses include smart products (AR / VR glasses) and ordinary glasses worn every day (such as vision correction glasses). Glasses have a bridge and temples that rotate and are mounted on the bridge. Specifically, the left and right temples are fixed to the bridge with screws. When it is necessary to open or close the temples during use, the temples need to be moved by flicking them. This process of flicking the temples to move them to the corresponding positions is rather inconvenient.

[0033] This utility model proposes a rotating shaft structure.

[0034] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the rotating shaft structure includes a mounting base 1, a rotating base 3, and a temple 4. The mounting base 1 is used to fix to the crossbeam of the mirror frame. The mounting base 1 has a connecting end 11, on which a hinged connecting portion 2 extending in a first direction is provided. Further reference... Figure 3 and Figure 4 The rotating base 3 has a first end and a second end opposite to each other. The first end is connected to the hinge connection 2 and rotates relative to the mounting base 1 on one side of the connecting side end 11. The temple 4 is slidably mounted relative to the rotating base 3 along a second direction. An elastic element 5 is connected between the temple 4 and the second end of the rotating base 3. Along the circumferential direction of the hinge connection 2, the distance between the periphery of the connecting side end 11 and the hinge connection 2 first increases and then decreases. The temple 4 has a front rotation stroke corresponding to the position where the distance increases and a rear rotation stroke corresponding to the position where the distance decreases. Under the action of an external force, the temple 4 rotates in the front rotation stroke, and the elastic element 5 deforms. When the temple 4 rotates into the rear rotation stroke, the temple 4 rotates in the rear rotation stroke under the action of the elastic restoring force of the elastic element 5.

[0035] In this invention, the rotating base 3 rotates synchronously with the temple 4. When the temple 4 is opened or closed, it is pushed to rotate by an external force. When the temple 4 rotates in the first part of its rotational stroke, the elastic element 5 deforms, increasing its elastic potential energy. When the temple 4 rotates to the second part of its rotational stroke, the external force applied to the temple 4 is stopped. The elastic element 5 can then deform under its own elastic restoring force, reducing its elastic potential energy and causing the temple 4 to rotate in the second part of its rotational stroke. When opening or closing the temple 4, an external force only needs to be applied to the temple 4 in the corresponding first part of its rotational stroke, eliminating the need to apply external force to the temple 4 throughout its entire rotation, thus improving the inconvenience of using eyeglasses.

[0036] Please see Figure 5 , Figure 6 and Figure 7 As the rotating seat 3 rotates, the second direction changes; within the rotation stroke of the rotating seat 3, any second direction intersects the first direction; specifically, the first direction is perpendicular to the second direction. When the temple 4 rotates on the front rotation stroke under the action of an external force, the elastic element 5 can gradually compress or gradually extend, which is not limited here. Specifically, when the temple 4 rotates on the front rotation stroke under the action of an external force, the elastic element 5 gradually compresses.

[0037] The end of the temple 4 facing the hinge connection 2 abuts against the periphery of the connecting side end 11. As the temple 4 rotates within the first rotational stroke and approaches the second rotational stroke, the distance between the temple 4 and the hinge connection 2 gradually increases, causing the deformation of the elastic element 5 to gradually increase. As the temple 4 rotates within the second rotational stroke and moves away from the first rotational stroke, the distance between the temple 4 and the hinge connection 2 gradually decreases, and the deformation of the elastic element 5 gradually increases. The first rotational stroke when the temple 4 is extended and the second rotational stroke when the temple 4 is closed are the same stroke but in different directions.

[0038] The periphery of the connecting end 11 has a first side 111 and a second side 112, the first side 111 and the second side 112 being adjacent and connected. The end of the temple 4 near the hinge connection 2 can abut against the first side 111 or the second side 112. When the temple 4 abuts against the end of the first side 111 away from the second side 112, the temple 4 is in a closed state; when the temple 4 abuts against the end of the second side 112 away from the first side 111, the temple 4 is in an open state.

[0039] On the first side 111, the distance between the first side 111 and the hinged connection 2 gradually increases along the direction close to the second side 112. On the second side 112, the distance between the second side 112 and the hinged connection 2 gradually increases along the direction close to the first side 111.

[0040] When the temple 4 is extended, it abuts against the first side 111 during its initial rotational stroke, and against the second side 112 during its subsequent rotational stroke. When the temple 4 is closed, it abuts against the second side 112 during its initial rotational stroke, and against the first side 111 during its subsequent rotational stroke.

[0041] Please see Figure 5 , Figure 6 and Figure 8 The first side 111 has a first arc edge 1111 at the end near the second side 112, and the second side 112 has a second arc edge 1121 at the end near the first side 111. The first arc edge 1111 and the second arc edge 1121 are coaxial and have the same radius. The line connecting the connection point of the first arc edge 1111 and the second arc edge 1121 to the axis of the hinge connection 2 passes through the axis of the first arc edge 1111. When the temple 4 abuts against the connection point of the first arc edge 1111 and the second arc edge 1121, that is, when the temple 4 passes the connection point of the first arc edge 1111 and the overlapping arc edge, the elastic member 5 reaches its maximum deformation.

[0042] The first side 111 also includes a first straight side 1112, which is connected to the end of the first arc side 1111 away from the second arc side 1121, and the first straight side 1112 and the first arc side 1111 are tangent at the connection point.

[0043] The second side 112 also includes a second straight edge 1122, which is connected to the end of the second arc edge 1121 away from the first arc edge 1111, and the second straight edge 1122 and the second arc edge 1121 are tangent at the connection point.

[0044] Please see Figure 1 , Figure 3 and Figure 4 A driving protrusion 41 is provided on the temple 4. The driving protrusion 41 is located between the first end and the second end of the rotating seat 3. The elastic element 5 is located between the driving protrusion 41 and the second end of the mounting seat 1. Correspondingly, the temple 4 rotates on the front rotation stroke under the action of external force, and the elastic element 5 is compressed and deformed.

[0045] When the temple 4 rotates within the front rotation stroke, the temple 4 moves away from the hinge connection 2, causing the drive protrusion 41 to approach the second end of the rotating seat 3, thereby causing the elastic member 5 to undergo compressive deformation. The drive protrusion 41 and the temple 4 can be bonded or otherwise arbitrarily fixedly connected, which is not limited here.

[0046] The temple 4 is provided with a mounting groove 42 at one end near the hinge connection 2. The driving protrusion 41 and the second end of the rotating seat 3 are both located in the mounting groove 42, which realizes the protection of the driving protrusion 41 and the second end of the rotating seat 3, and helps to ensure the sliding between the rotating seat 3 and the temple 4.

[0047] The elastic element 5 includes a spring that extends along a second direction. One, two, or more springs may be provided, without limitation; specifically, one spring is provided. The two ends of the spring are respectively fixedly connected to the driving protrusion 41 and the second end of the rotating seat 3.

[0048] The second end of the rotating seat 3 has a support plate 33, and the spring is disposed between the support plate 33 and the driving protrusion 41.

[0049] The driving protrusion 41 has a receiving groove 411 on the side facing the second end of the mounting base 1, and one end of the elastic member 5 is located in the receiving groove 411. By providing the receiving groove 411, one end of the elastic member 5 can be limited to improve the stability of the elastic member 5. The receiving groove 411 can also provide deformation space for the elastic member 5 to increase the size of the elastic member 5.

[0050] Please see Figure 1 , Figure 3 and Figure 4The rotating seat 3 has a groove 31 extending along a second direction, and the driving protrusion 41 is located within the groove 31. The groove 31 limits the sliding of the driving protrusion 41 and reduces interference between the driving protrusion 41 and the rotating seat 3.

[0051] The rotating base 3 includes two spaced-apart connecting plates 32 and a support plate 33 connected between the two connecting plates 32; the sliding groove 31 is defined between the two connecting plates 32. The two connecting plates 32 and the support plate 33 can be integrally or otherwise fixedly connected, which is not limited here. Specifically, the integral connection between the connecting plates 32 and the support plate 33 ensures the connection strength between the connecting plates 32 and the support plate 33.

[0052] The mounting base 1 has two ear plates 12, which are spaced apart along a first direction. The rotating base 3 has two connecting plates 32, which are spaced apart along a first direction. The hinged connection part 2 includes two hinged connecting shafts 21 extending along the first direction. The hinged connecting shafts 21, the ear plates 12, and the connecting plates 32 correspond one-to-one. The connecting plates 32 are rotatably connected to the ear plates 12 through the hinged connecting shafts 21.

[0053] By providing two ear plates 12 and two connecting plates 32, the stability of the connection between the rotating seat 3 and the mounting seat 1 is enhanced. The shapes of the ear plates 12 and the connecting plates 32 are not limited here. Specifically, the connecting side end 11 includes two connecting plates 32.

[0054] A clearance groove 121 is formed between the two ear plates 12, and the two connecting plates 32 are located within the clearance groove 121. By providing the clearance groove 121, interference between the connecting plate 32 and the mounting base 1 can be avoided when the connecting plate 32 rotates.

[0055] Please see Figure 1 , Figure 2 and Figure 4 At least one support portion 6 is provided between the two connecting plates 32. By providing the support portion 6, the two connecting plates 32 can be supported, thereby reducing the opposite bending that occurs between the two connecting plates 32.

[0056] At least two support portions 6 are provided, and the at least two support portions 6 are spaced apart around the hinge connection portion 2. By using at least two support portions 6, the deformation of the two connecting plates 32 at the hinge connection portion 2 can be reduced.

[0057] The support portion 6 may be provided in two, three or more forms, which is not limited here; specifically, two support portions 6 are provided. The side of the two support portions 6 that are close to each other is provided with a relief groove 61 to avoid interference between the support portion 6 and the hinge connection portion 2.

[0058] This utility model also proposes a pair of glasses, which includes a rotating shaft structure. The specific structure of the rotating shaft structure is as described in the above embodiments. Since this pair of glasses adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0059] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
