Similarly, one end of the second rack 540 is fixedly connected to the second lens 320, and the area near the other end is engaged with the gear 520.

Referring to fig. 1 and 6, fig. 6 is a schematic structural diagram of an adjusting assembly of eyeglasses according to another embodiment of the present invention. If the viewing angle of fig. 3 is a front view, the viewing angle of fig. 6 is a top view. In other embodiments, the gear 520 may have an axial direction perpendicular to the length direction of the temple 200, and one of the first rack 530 and the second rack 540 is located inside the gear 520, and the other is located outside the gear 520. To ensure that first lens 310 is in the same plane as second lens 320, it is necessary to provide a transition 700 connecting second rack 540 to second lens 320 or a transition connecting first rack 530 to first lens 310. For example, the first rack 530 is located at an inner side of the gear 520, and the second rack 540 is located at an outer side of the gear 520. Transition piece 700 extends along the length of temple 200, which is the diameter of gear 520, and transition piece 700 connects second rack 540 with second lens 320. In this embodiment, the nose pad 400 protrudes more outward from the frame 100 to accommodate the gear 520, the second rack 540, and the transition piece 700 protruding outward from the two lenses.

In some embodiments, the adjustment assembly further comprises a first elastic member 550 and a knob 560, the knob 560 is located outside the nose pad 400, and other components of the adjustment assembly, such as the adjustment rod 510, the gear 520, the first rack 530, the second rack 540 and the first elastic member 550, are located inside the nose pad 400. One end of the adjusting rod 510, which extends out of the nose pad 400, is fixedly connected to the knob 560, the first elastic member 550 is sleeved on the adjusting rod 510, one end of the first elastic member 550 is fixedly connected to the knob 560, and the other end is fixedly connected to the gear 520. When the knob 560 is pressed, the knob 560 drives the adjusting rod 510 to move together toward the inside of the nose pad 400, the distance of the adjusting rod 510 exposed outside the nose pad 400 is shortened, and one end of the adjusting rod 510 close to the gear 520 is connected to the gear 520 to switch to the unlocking state. During the movement, the first elastic member 550 will be compressed, and when the knob 560 stops being pressed, the adjusting rod 510 and the knob 560 move in a direction away from the gear 520 under the driving of the resilience of the first elastic member 550, and one end of the adjusting rod 510 close to the gear 520 is separated from the gear 520, so as to switch to the locking state. Specifically, the first elastic member 550 may be a spring.

Referring to fig. 3 to 5, in some embodiments, a limiting hole is formed in the gear 520, a first insertion portion 511 is formed at one end of the adjusting lever 510 close to the gear 520, the first insertion portion 511 has a shape matching the shape of the limiting hole, and when the knob 560 is pressed, the first insertion portion 511 is inserted into the limiting hole to connect the adjusting lever 510 and the gear 520. At this time, if the knob 560 is rotated, the gear 520 is rotated synchronously with the adjusting rod 510, so as to drive the first rack 530 and the second rack 540 to move in opposite directions. The first elastic member 550 is not only compressed but also distorted when the knob 560 is rotated. When the knob 560 is loosened, the first elastic member 550 moves reversely, the first inserting portion 511 exits the limiting hole, and meanwhile, the first elastic member 550 rotates reversely to reset and is not distorted any more.

In some embodiments, the eyewear further includes a locking assembly also disposed within the nose piece 400. The locking assembly includes a locking rod 610 and a second elastic member 620, and the locking rod 610 and the adjustment lever 510 are respectively located at both ends of the gear 520. The locking rod 610 is slidably connected to the nose piece 400, and the locking rod 610 can slide in the nose piece 400. The locking rod 610 is provided with a boss 611 at an end thereof away from the gear 520, the second elastic member 620 is sleeved on the locking rod 610, and one end of the second elastic member 620 is fixedly connected with the boss 611, and the other end is fixedly connected with the gear 520. In the unlocked state, the first inserting-connecting portion 511 is inserted into the limiting hole and abuts against the locking rod 610, and pushes the locking rod 610 away from the gear 520, and at this time, the second elastic member 620 is stretched. In the locked state, after the knob 560 is stopped being pressed, the first inserting portion 511 is driven by the resilience of the first elastic member 550 to exit the limiting hole, the first inserting portion 511 is no longer abutted against the locking rod 610, and the locking rod 610 moves towards the gear 520 to lock the gear 520 under the driving of the resilience of the second elastic member 620, so that the gear 520 cannot rotate, and the first lens 310 and the second lens 320 are locked at the current position. Therefore, the glasses can be prevented from being mistakenly bumped to cause the change of the lens distance in the use process.

Specifically, in some embodiments, a second insertion portion 612 is disposed on an end of the locking rod 610 close to the gear 520, and the second insertion portion 612 matches with the shape of the limiting hole. In the locked state, the second insertion part 612 is inserted into the limiting hole to limit the gear 520, and at this time, the gear 520 cannot rotate. If the knob 560 is pressed, the first inserting portion 511 is inserted into the limiting hole, and the first inserting portion 511 abuts against the second inserting portion 612, so that the second inserting portion 612 exits from the limiting hole, and thus the locking state can be switched to the unlocking state, and at this time, the second elastic element 620 is stretched. When the knob 560 stops being pressed, the first insertion portion 511 is withdrawn from the position-limiting hole under the driving of the resilient force of the first elastic member 550, and the second insertion portion 612 is inserted into the position-limiting hole under the driving of the resilient force of the second elastic member 620, so that the unlocking state can be switched to the locking state.

Alternatively, in other embodiments, a first magnetic member is disposed on the locking rod 610 near one end of the gear 520, and a second magnetic member is disposed on the gear 520, so that the two magnetic members attract each other. Under the locking state, the second magnetic part contacts with the first magnetic part, and the magnetic attraction of the second magnetic part and the first magnetic part limits the gear 520 so as to prevent the gear 520 from rotating along with the movement of the rack when the lens is pulled, thereby locking. If the knob 560 is pressed, the first inserting portion 511 is inserted into the limiting hole and abuts against the first magnetic member, so that the first magnetic member is pushed out in a direction away from the gear 520, and when the first magnetic member is separated from the second magnetic member, the locking state can be switched to the unlocking state, and the gear 520 can rotate.

Preferably, in some embodiments, a sliding groove is formed in the nose pad 400, and when the knob 560 is pressed or released, the locking rod 610 can slide in the sliding groove, and the locking rod 610 can be guided and limited by the sliding groove, so that the movement of the locking rod 610 is more stable. Similarly, a sliding groove for sliding the adjusting rod 510 can be further provided in the nose pad 400.

Preferably, in some embodiments, the limiting hole has a polygonal shape, and correspondingly, the first insertion portion 511 and the second insertion portion 612 also have a polygonal structure. Specifically, the limiting hole penetrates through the thickness direction of the gear 520, and the limiting hole may be pentagonal, triangular, or the like. Alternatively, the limiting hole may be a waist-shaped hole, or may be in other irregular shapes.

Preferably, in some embodiments, the size of each of the first and

second insertion parts

511 and 612 is slightly smaller than the size of the limiting hole. In the unlocked state, the first insertion part 511 is in clearance fit with the limiting hole; in the locked state, the second insertion portion 612 is in clearance fit with the limiting hole. Therefore, the first inserting-connecting part 511 and the second inserting-connecting part 612 can easily enter and exit the limiting hole and are not easy to be clamped.

Preferably, in some embodiments, the knob 560 is provided with anti-slip threads. In this way, the knob 560 is not likely to slip when turned. Alternatively, a rubber ring may be sleeved on the outside of the knob 560 to increase the friction force.

Referring to fig. 1 and 2, fig. 2 is a schematic structural view of a frame and a first lens of the glasses in fig. 1. In some embodiments, the bottom end of the frame 100 is provided with a slide rail 110, the top of the first lens 310 and the top of the second lens 320 are both provided with a slider 311, and the slider 311 is slidably connected to the slide rail 110. Specifically, the frame 100 has an inverted "U" shape in cross section to form the rail 110, and when the knob 560 is rotated, the slider 311 can slide along the rail 110 with the lens for guiding and limiting. When the sliding block 311 slides to the two ends of the sliding rail 110, it is blocked, that is, the position adjustment limit position is reached, that is, the maximum distance or the minimum distance of the lens. In addition, the number of teeth arranged on the first rack 530 and the second rack 540 also affects the limit position of the position adjustment, and the larger the number of teeth, the larger the range of adjustment is. It is possible to select to provide teeth on part or all of the areas of the first and

second racks

530 and 540 according to the design and manufacture.

In some embodiments, the glasses in the above embodiments are AR glasses, and the first lens 310 and the second lens 320 are both display modules, and the distance between the two display modules of the AR glasses can be adjusted. Therefore, when different wearers wear the AR glasses, the distance between the two display modules can be adjusted according to the self interpupillary distance, so that the interpupillary distance matching degree is higher, the watching effect is optimized, and the user experience is improved.
