The telescopic rotary shaft assembly 30 rotatably connects the temples 12 to the frame 11. The telescoping spindle assembly 30 has a retracted state and an extended state. When the telescopic rotating shaft assembly 30 is in the retracted state, the temple 12 abuts against the frame 11; when the telescopic rotary shaft assembly 30 is in the extended state, the temple 12 is away from the frame 11 to form a deformation gap between the temple 12 and the frame 11. With such a configuration, when users with different head sizes use the AR glasses 1, the telescopic rotating shaft assembly 30 of the AR glasses 1 can be freely adjusted to switch between the retracted state and the extended state, so as to adjust the size of the deformation gap formed between the temple 12 and the frame 11, thereby increasing the distance between the frame 11 and the end of the temple 12, and allowing the users with the larger head sizes to wear the AR glasses 1. In other words, the telescopic hinge assembly 30 can be switched between the retracted state and the extended state to adjust the deformation gap formed between the temple 12 and the frame 11, so that the deformation gap between the temple 12 and the frame 11 functions as an extension of the temple 12, thereby being adapted to users with different head sizes.

Further, when the telescopic rotary shaft assembly 30 is in the extended state, since the deformation gap is formed between the temple 12 and the frame 11, the temple 12 does not abut against the frame 11, so that the temple 12 can be turned to the outside of the eyeglass body 10. In this way, the distance between the two temples is increased, so that the AR glasses can be worn also facing the user with the larger lateral size of the head.

Specifically, as shown in fig. 2, 3 and 4, according to an embodiment of the present application, the telescopic rotating shaft assembly 30 includes a frame connecting member 31 connected to the frame 11, a rotating shaft 32 rotatably provided to the frame connecting member 31, and a sliding contact assembly 33 rotatably provided to the rotating shaft 32, the sliding contact assembly 33 is connected to the temple 12, and when the temple 12 slides with respect to the frame 11, the telescopic rotating shaft assembly 30 is switched between the retracted state and the extended state. So configured, the temple 12 slides relative to the frame 11 against the sliding contact assembly 33 to form a gap between the frame 11 and the temple 12, so that the telescopic spindle assembly 30 is switched between the retracted state and the extended state. The telescopic rotary shaft assembly 30 is connected in a sliding way, so that the telescopic rotary shaft assembly 30 has enough rigidity and can bear larger load.

It is noted that the sliding connection member 33 may be connected to the frame 11, and correspondingly, the frame connecting member 31 and the rotation shaft 32 provided to the frame connecting member 31 may be provided to the temple 12. So configured, it is also possible to achieve switching of the telescopic rotary shaft assembly 30 between the contracted state and the expanded state in a sliding manner.

More specifically, as shown in fig. 2, 3, 4 and 5, according to an embodiment of the present application, the sliding connection assembly 33 includes a slider 331 rotatably connected to the rotation shaft 32, a temple connector 332 slidably connected to the slider 331, and a restoring member 333 disposed between the slider 331 and the temple connector 332, the temple 12 is fixedly connected to the temple connector 332, and when the temple 12 is applied with an external force to be away from the frame 11, the temple connector 332 slides along the slider 331 to accumulate potential energy in the restoring member 333; when the external force applied to the temple 12 is removed, the temple connector 332 slides along the slider 331 to be adjacent to the frame 11 by the restoring member 333. So configured, the reset element 333 is capable of switching the telescopic rotating shaft assembly 30 to a contracted state when the AR glasses 1 are not worn. At the same time, providing a clamping force to the temple 12 when the telescoping spindle assembly 30 is in the extended state makes the AR glasses 1 more robust for the user. In other words, the telescopic rotary shaft assembly 30 is maintained in the contracted state when the AR glasses 1 are not worn, and the telescopic rotary shaft assembly 30 is pulled apart and maintained in the extended state when the AR glasses are worn, at which time the restoring member 333 accumulates potential energy, and the restoring member 333 can provide a pushing force to slide the temple connector 332 toward the frame connector 31 in order to release the accumulated potential energy. And under this pushing force, the temple 12 can provide a grip to the user's ear, preventing the AR glasses 1 from slipping off.

Alternatively, as shown in fig. 5 and 6, according to an embodiment of the present disclosure, the sliding rod 331 includes a fixing rod 3311 and a position-limiting rod 3312 rotatably disposed on the rotating shaft 32, one end of the position-limiting rod 3312 is fixed to the fixing rod 3311, and the other end of the position-limiting rod 3312 is provided with a position-limiting block 3313.

The temple spring 3330 is a compression spring, and when the retractable shaft assembly 30 is switched from the retracted state to the extended state, the slider 3321 slides toward the position-limiting block 3313, and the temple spring 3330 is compressed to generate an elastic force. In other words, when the AR glasses are worn by a user with a large head size, the telescopic hinge assembly 30 is in an extended state, and the temple spring 3330 is compressed to provide a clamping force to the temple 12 toward the frame 11.

Note that the temple spring 3330 may be a tension spring. The temple spring 3330 is sleeved on the position-limiting rod 3312, but one end of the temple spring 3330 is connected to the slider 3321 and the other end is connected to the rotation shaft 32. With this arrangement, when the retractable shaft assembly 30 is switched from the retracted state to the extended state, the sliding block 3321 slides toward the stopper 3313 and toward the stopper 3313, and the temple spring 3330 is stretched to generate an elastic force, thereby providing the above-mentioned clamping force.
