In this embodiment, the third screw holes 3213 and the third screw posts 250 are three in number and distributed in a delta shape, which is helpful to improve the connection stability.

In some embodiments of the present application, referring to fig. 6 to 8, the rotating shaft portion 312 includes a first rotating shaft 3121 and a second rotating shaft 3122 which are coaxially disposed, the second rotating shaft 3122 is disposed at a bottom of the first rotating shaft 3121, a diameter of the second rotating shaft 3122 is smaller than a diameter of the first rotating shaft 3121, and a stop step surface 3126 is formed at a meeting intersection of the first rotating shaft 3121 and the second rotating shaft 3122. The rotating shaft connecting portion 322 is rotatably connected to the second rotating shaft 3122, that is, the second rotating shaft 3122 is rotatably disposed in the shaft hole 3221. The spindle connecting portion 322 is clearance-fitted with a bottom end surface (i.e., the stopper step surface 3126) of the first spindle 3121 to ensure that the spindle connecting portion 322 can rotate around the second spindle 3122.

The bottom end surface of the first rotating shaft 3121 is provided with a groove portion 3125, the groove portion 3125 extends for a distance along the circumferential direction of the first rotating shaft 3121, the top end surface of the second rotating shaft 3122 is correspondingly provided with a protruding portion 3222, and the protruding portion 3222 is located in the groove portion 3125 and can move along the groove portion 3125 to limit the rotating range of the movable shaft portion 320. When the temples 200 are rotated inward until the protrusions 3222 abut against one end of the groove portions 3125, the temples 200 reach a maximum angle at the time of inward folding. When the temples 200 are rotated outward until the protrusions 3222 abut the other ends of the groove portions 3125, the temples 200 reach a maximum angle of outward bending. By limiting the folding angle of the temples 200, it is possible to prevent the temples 200 from being folded at an excessively large angle to damage the internal wiring.

The top end of the first rotation shaft 3121 is provided with an extension portion 3123, and a stop surface 3124 is provided on the side surface of the extension portion 3123. The extension 3123 extends from the upper end of the cover plate assembly 500 to form a locking position with the cover plate assembly 500, and also plays a certain role in limiting the axial movement of the rotating shaft 312, further improving the structural stability.

In this embodiment, referring to fig. 15, when the temples 200 are folded inward to the maximum angle, the folding angle of the temples 200 is less than 90 °. Referring to fig. 14, when the temple 200 is not completely unfolded, the second bending arm 612 is not in contact with the stop surface 3124, when the temple 200 is gradually unfolded in a direction parallel to the frame 100, the second bending arm 612 gradually approaches the stop surface 3124 until the second bending arm 612 abuts against the stop surface 3124, at which time the protrusion 3222 does not abut against the end of the groove portion 3125, if the circumference of the head of the user is large, the temple 200 may be continuously bent to the outside of the frame 100, at which time the second bending arm 612 is compressed by the abutment of the stop surface 3124, and when the protrusion 3222 abuts against the end of the groove portion 3125, the temple 200 is bent outward to a maximum angle, and cannot be further bent outward. The second bending arm 612 will now give a resilient force to the stop surface 3124, so that the temple arm 200 will tend to move towards the inner side of the frame 100, and further the temple arm 200 will have a certain holding force when bent in the opposite direction, so that the temple arm assembly is more reliably worn on the head of the user and is less prone to falling off. Because the stressed compression amount of the plate spring 610 is automatically adaptive to the size of the head circumference of the user, the wearing comfort is further improved.

In this embodiment, the second folded arm 612 is designed to come into abutment against the stop surface 3124 when the temple arm 200 is still 5-10 ° away from parallel with the frame 100. When the temples 200 are reversely bent toward the outer side of the frame 100 by 5 to 10 °, the protrusions 3222 abut against the groove portions 3125 to reach a maximum angle of the reverse bending. The temples 200 may have different reverse bending angles by devising the positions between the protrusions 3222 and the groove portions 3125.

In some embodiments of the present application, the foldable temple assembly further includes a locking assembly 400, referring to fig. 3 to 5, the locking assembly 400 is disposed on the rotating shaft portion 312 to limit the displacement of the rotating shaft connecting portion 322 along the axial direction of the rotating shaft portion 312, so that the rotational connection between the fixed shaft portion 310 and the movable shaft portion 320 is more reliable. Locking assembly 400 includes dish spring 410, and when mirror leg 200 was buckled, dish spring 410 provided the damping force for the rotation of movable shaft part 320 to have certain damping effect when making mirror leg 200 fold, improve user's use and experience.

The locking assembly 400 further includes a spacer 430 and a locking nut 420, the spacer 430 is disposed between the disc spring 410 and the locking nut 430, the disc spring 410, the spacer 430 and the locking nut 420 are sequentially sleeved on the second rotating shaft 3122, and the locking nut 420 is screwed to the bottom end of the second rotating shaft 3122 to achieve axial limiting of the rotating shaft connecting portion 322, the spacer 430 and the disc spring 410.

By adjusting the tightness of the locking nut 420, the disc spring 410 can provide different damping forces, thereby providing different damping effects to the temples 200.

In some embodiments of the present application, the foldable temple assembly further comprises a cover plate assembly 500, and referring to fig. 14, a receiving cavity 530 is formed inside the cover plate assembly 500, a first relief opening 540 is formed at a side of the cover plate assembly 500 close to the frame 100 and extends into the first cavity 110 of the frame through the frame opening 120, and a second relief opening 550 is formed at a side of the cover plate assembly 500 close to the temple 200 and extends into the second cavity 210 of the temple through the temple opening 220.
