[0036] Embodiment Four

[0037] Refer to the appendix Figures 7 to 10On the basis of the third embodiment, in order to limit the maximum opening angle of the glasses leg 20, the angle adjustment limiter includes a positioning column 14 and a positioning socket 15, the positioning column 14 is fixed to the bottom end of the sleeve 19, the positioning socket 15 is provided on the bottom plate of the hinge seat 3, and the positioning column 14 is movably plugged into the positioning socket 15, the positioning column 14 and the positioning socket 15 correspond one to one, and there are thirty-six positioning sockets 15, and the thirty-six positioning sockets 15 are arranged in a circular shape along the top surface of the bottom plate of the distance sensor 13, and the angle between two adjacent positioning sockets 15 is ten degrees, and the height of the positioning column 14 is less than the retractable distance of the elastic supporting mechanism, and the elastic supporting mechanism includes a rubber gasket 16 and an elastic support ring 17, and the elastic support ring 17 is a truncated cone ring. Structure, the cross-section of the annular side plate of the elastic support ring 17 is an arc-shaped structure, the rubber gasket 16 is fixed to the side with a larger notch area of ​​the elastic support ring 17, the two groups of elastic support rings 17 are symmetrically distributed, and the other sides with a smaller notch area of ​​the two groups of elastic support rings 17 are in contact, the rubber gasket 16 on the surface of the bottom elastic support ring 17 is fixed to the top of the sleeve 19, and the elastic support ring 17 is sleeved on the outside of the limiting shaft column 5, the elastic support ring 17 is between the sleeve 19 and the top plate of the hinge seat 3, and after the glasses leg 20 is lifted up, the sleeve 19 is driven to lift and squeeze the two groups of elastic support rings 17, and after the positioning column 14 is detached from the corresponding positioning socket 15, the sleeve 19 can rotate around the limiting shaft column 5, and after the glasses leg 20 falls, the positioning column 14 is inserted into the positioning socket 15 to limit the sleeve 19.

[0038] In actual use, when the positioning pin 14 is inserted into the positioning hole 15, the sleeve 19 will not rotate around the limiting shaft column 5, that is, at this time, the maximum angle of the two sets of eyeglass legs 20 is limited, and the user adjusts the opening angle of the two sets of eyeglass legs 20 according to the width of his face. After the angle is adjusted and the user wears the eyeglasses, the airbag cushion 22 is clamped between the eyeglass legs 20 and the wearer's face to prevent the eyeglass legs 20 from pressing marks on the wearer's face, and the gap between the eyeglass legs 20 and the wearer's face is filled with the airbag cushion 22, thereby preventing the AR glasses body 1 from shaking when worn; the specific operation of adjusting the opening angle of the eyeglass legs 20 is to hold the AR glasses body 1 with one hand and pinch the eyeglass legs 20 with the other hand, and pull the eyeglass legs 20 upward to drive the sleeve 19 to slide up along the limiting shaft column 5. At this time, the two sets of elastic support rings 17 are elastically deformed under pressure. After the sleeve 19 is lifted, the sleeve 19 drives the positioning pin 1 4 is pulled out from the positioning socket 15. At this time, the sleeve 19 is no longer restricted, that is, the sleeve 19 can rotate around the limiting shaft column 5. The sleeve 19 can be driven to rotate by moving the temple 20. After rotating to the desired opening angle, the temple 20 is released, and the two sets of elastic supporting rings 17 rebound and push the sleeve 19 to fall and reset. When the positioning pin 14 and the positioning socket 15 correspond, the positioning pin 14 directly falls into the positioning socket 15 to limit the sleeve 19. If the positioning pin 14 is blocked by the bottom plate of the hinge seat 3, that is, the positioning pin 14 is between two adjacent positioning sockets 15, it is necessary to slightly move the temple 20 left and right to drive the sleeve 19 to rotate, so that the positioning pin 14 falls into the nearest positioning socket 15 to limit the sleeve 19. In this way, the two sets of temples 20 are limited after the opening angle is adjusted, which is convenient for the AR glasses body 1 to adjust the clamping force suitable for users with different face widths when wearing them.
