[0022] With reference to the drawings. The hinge applied to the AR glasses is taken as an example in the embodiment, the hinge is a double-shaft hinge, comprising a fixed frame 100, a first side rotating structure A and a second side rotating structure B, the first side rotating structure and the second side rotating structure both comprise a connecting frame 200, a first connecting rod 1, a connecting shaft 3 and a torsion elastic return mechanism; a synchronous reverse rotating connecting mechanism is further connected between the first side rotating structure and the second side rotating structure, so that the first side rotating structure and the second side rotating structure are synchronously and reversely rotated in the second stage rotating range. The connecting frame 200 of the first side rotating structure A and the connecting 200 of the second side rotating structure B can be connected with the frame and the leg of the AR glasses respectively.

[0023] The torsion elastic return mechanism comprises a fixed shaft 4 and a torsion connecting rod 2, the fixed shaft 4 is fixedly connected with the fixed frame 100, the first end of the torsion connecting rod 2 is connected with the fixed shaft 4, the second end of the torsion connecting rod 2 is connected with the connecting shaft 3, the first end of the first connecting rod 1 is fixedly connected with the connecting frame 200, and the second end is connected with the connecting shaft 3.

[0024] The fixed frame 100 is further provided with a support site 101 for the first connecting rod, so that after the first connecting rod 1 rotates around the connecting shaft 3 from the first angle to the second angle, in the rotation range from the second angle to the third angle, the first connecting rod cooperates with the support site 101 to form a rod rotating around a new center, and is driven by the second end to rotate the torsion connecting rod 2 to receive the rotation rebound force provided by the torsion rebound mechanism. The first angle to the second angle is the first stage rotation range, and the second angle to the third angle is the second stage rotation range. The torsion rebound mechanism provides a rebound function towards the second angle in the second stage rotation range for the connecting frame 200.

[0025] The first angle corresponds to the angle when the temple is folded, the second angle corresponds to the initial angle when the temple is opened to the normal use (for example, for the smallest head type), and the third angle corresponds to the maximum opening angle (for example, for the largest applicable head type). The second angle can belong to the first stage rotation range or the second stage rotation range. In the first stage rotation range outside the second angle, the first connecting rod 1 has a gap with the support site. In the second stage rotation range, the first connecting rod 1 is in contact with the support site.

[0026] For the support site 101, it can be a part on the fixed frame 100, or a part of the fixed frame 100 itself, and can be a point (line), or an arc surface (i.e. the center of the arc surface is the rotation center of the first connecting rod 1 in the second stage rotation, so that the movement is more stable and saves space). The support site 101 cooperates with the middle part of the first connecting rod 1, and the part of the first connecting rod 1 that cooperates with it is also an arc surface 10.

[0027] The synchronous reverse rotation connecting mechanism includes a movable control plate 5 and cooperates with the first connecting rod 1, so that the axial length can be further reduced. The control plate 5 is provided with a control groove 51 cooperating with the first connecting rod 1 of the first side rotation structure and a control groove 52 cooperating with the first connecting rod 1 of the second side rotation structure, and the first connecting rod 1 of the first side rotation structure and the first connecting rod 1 of the second side rotation structure are respectively provided with pins 112, 122 inserted into the respective control grooves. The rotation of the first connecting rod on one side enables the pin thereon to drive the control plate to move through the control groove cooperating therewith, and the movement of the control plate enables the first connecting rod on the other side to synchronously and reversely rotate through the control groove on the other side acting on the pin on the other side.

[0028] The control plate 5 is provided with a guide groove, and the fixed frame 100 is provided with a guide structure of the control plate, and the guide groove and the guide structure are guided and matched. In the embodiment, the fixed shaft can be used as the guide structure, and the structure is further simplified. The specific structure is as follows: the guide structure is the fixed shaft 4 of the rotating structure on the first side and the fixed shaft 4 of the rotating structure on the second side, the control plate 5 is respectively provided with a guide groove 53 matched with the fixed shaft of the rotating structure on the first side and a guide groove 54 matched with the fixed shaft of the rotating structure on the second side, and the guide grooves are sleeved outside the fixed shafts.

[0029] The first connecting rod 1 is connected through the roll 7 and the connecting shaft 3. The roll 7 is a sleeve provided with an axial slit and can be elastically expanded. The roll 7 is clamped outside the connecting shaft 3, the output torsion of the roll 7 is less than the rebound force of the torsion rebound mechanism, and when the first connecting rod 1 does not contact the support part 101, the first connecting rod 1 can rotate around the connecting shaft 3. In this way, the phased rotation can be realized by the configuration between the torsion at the connecting shaft and the torsion at the torsion rebound mechanism, and better hand feeling and the posture of the connecting frame are provided.

[0030] For the torsion mechanism, the fixed shaft 4 is sleeved with the first cam 61 and the second cam 62 located at the first end of the torsion connecting rod and the disc spring sheet stack 63, and the disc spring sheet stack 63 is used to press the first cam 61 and the second cam 62. In this way, the characteristics of the disc spring sheet stack can be fully utilized by the small-angle rotation characteristics of the torsion connecting rod 2, and the rebound force is more suitable. The first cam 61 can be arranged on the fixed frame 100.

[0031] In the embodiment, the wearing device hinge is provided with two control plates 5, which are matched with two ends of the connecting shaft 3 respectively, and the first connecting rod 1 and the torsion connecting rod 2 are two respectively. The structural stability can be improved.
