The temple 100 is rotatably connected with the frame 200, and the temple 100 can rotate around the rotation axis Y1. The inside of the temple 100 is formed with a hollow cavity 110 of the temple for installing other components. The temple rotation locking assembly 600 is arranged in the cavity 210 of the mirror frame, and is used to lock the temple 100 at a specific rotation position, so as to realize the rotation locking of the temple 100 relative to the mirror frame 200 . FIG. 9 hides the temple 100 in order to facilitate the embodiment of the structure of the temple rotation assembly 500 . The temple rotating assembly 500 includes a first sliding shaft 510 and a rotating arm 520 . The two ends of the first sliding shaft 510 are respectively fixedly connected with the two inner sidewalls of the temples 100 that are vertically opposite to each other, and are located in the hollow cavity 110 of the temples. The length direction of the first sliding shaft 510 is perpendicular to the length direction L of the temples 100. . The first sliding shaft 510 rotates around the rotation axis Y1 together with the temple 100 . The rotating arm 520 is extended along the length direction L of the temple 100. One end of the rotating arm 520 close to the mirror frame 200 extends from the front side wall 120 of the temple 100, and then extends into the hollow cavity 210 in the mirror frame.

The rotating arm 520 is provided with a long opening 523 along its length direction (ie, the length direction L of the temple 100 ), and the first sliding shaft 510 passes through the long opening 523 and moves along the long opening 523 .

The temple 100 rotates around the rotation axis Y1 under the action of the external force, and drives the first sliding shaft 510 to rotate along with the temple 100. The first sliding shaft 510 moves along the elongated opening 523 while rotating around the rotation axis Y1. The first sliding shaft 510 will drive the rotating arm 520 to also perform a synchronous rotating action around the rotating axis Y1. After the temple 100 is rotated to a specific position, the rotation locking assembly 600 of the temple can lock and fix the rotating arm 520 , thereby realizing the rotation and fixation of the temple 100 .

Further, the temple rotation assembly 500 further includes a first spring 530, the first spring 530 is arranged between the first sliding shaft 510 and the rotating arm 520 along the length direction L of the temple 100, and the first spring 530 is used to rotate the temple 100 provides a force to keep the temple 100 in close contact with the frame 200 all the time. When the temple 100 rotates around the rotation axis Y1, referring to FIG. 10, the front side wall 120 of the temple 100 will be at the edge of the outer side wall of the mirror frame 200 (the intersection of the rear side wall 221 of the mirror frame and the left side wall 225 or the right side wall 222). ) as the pivot point for rotation. During the rotation of the temple 100 from one side (rear side) of the temple 200 to the outside (left or right) of the temple 200 , the first sliding shaft 510 first slides along the elongated opening 523 toward the rear end of the temple 100 , the distance between the first sliding shaft 510 and the rear end of the rotating arm 520 is reduced; The distance is reduced. During the rotation process of the temple 100, the first spring 530 is always in a compressed state, and the first spring 530 will give the first sliding shaft 510 a restoring force that points to the mirror frame 200, so that the temple 100 can always be kept close to the mirror frame 200. , so that the electrical contact between the first electrical contact 930 provided on the temple 100 and the second electrical contact 940 provided on the mirror frame 200 is more stable at all times, thereby improving the reliability of the AR glasses.

Referring to FIGS. 11 to 13 , in order to reflect the structure of the temple rotation locking assembly 600 in FIGS. 11 and 12 , the front side wall 224 of the mirror frame 200 is hidden, and FIG. 13 is a cross-sectional schematic diagram of the temple rotation locking assembly 600 . The temple rotation locking assembly 600 includes a rotation locking shaft 610 , a second spring 630 sleeved on the rotation locking shaft 610 , a rotation locking disc 620 , and a rotation locking switch 640 abutting against the rotation locking disc 620 . . The second spring 630 is pressed between the rotation locking disk 620 and the rotation locking shaft 610 to provide a restoring force for the rotation locking disk 620 . The rotation locking shaft 610 is fixedly connected with the mirror frame 200 . The rotary lock switch 640 is movably disposed on the side wall of the mirror frame 200 and exposed from the side wall of the mirror frame 200 to facilitate manual operation by the user. In this embodiment, the rotary lock switch 640 is preferably exposed from the upper side wall 223 of the mirror frame for easy operation. The rotating arm transverse portion 521 is rotatably connected to the rotation locking shaft 610 , and is synchronously rotatably connected to the rotating locking disk 620 along the rotation locking shaft 610 . The rotation locking disc 620 and the mirror frame 200 are detachably connected, and the connection or disengagement between the rotation locking disc 620 and the mirror frame 200 is realized through the rotation locking switch 640 .

Manually press the rotary lock switch 640 to release the connection between the rotary lock plate 620 and the mirror frame 200 , and rotate the temple 100 to drive the lateral portion 521 of the rotating arm to rotate around the rotation lock shaft 610 . After the rotation is in place, the rotating locking opening 640 is released, and the connection between the rotating locking disc 620 and the mirror frame 200 is restored. Since the lateral part 521 of the rotating arm and the rotating locking disc 620 are synchronously rotationally connected, the mirror legs can be realized. Locking fixed after 100 turns.

Further, the detachable connection between the rotation locking disk 620 and the mirror frame 200 is achieved by the following structure: the inner side wall of the mirror frame 200 is provided with a locking connecting plate 240 with a plurality of locking holes 241 thereon. The rotation locking shaft 620 is fixedly connected with the locking connecting plate 240 to realize the fixed connection between the rotation locking shaft 620 and the mirror frame 200 . The rotary lock switch 640 includes a key portion 641 and at least two abutting posts 642 connected to the key portion 641 , and the key portion 641 and the abutting posts 642 are integrally formed. The rotation locking disc 620 includes a turntable body 621 and at least two guide posts 622 connected to the turntable body 621. The turntable body 621 and the guide posts 622 are integrally formed, and the second spring 630 is pressed on the turntable body 621 and the rotation locking shaft. Between 610 , the guide post 622 is synchronously connected to the rotating arm 520 for rotation. The number of the abutment posts 642 and the guide posts 622 is the same, and the number of the locking holes 241 is greater than that of the guide posts 622 . The guide post 622 is movably disposed in the locking hole 241 , and the lower end of the abutting post 642 abuts the upper end of the guiding post 622 .

When the temple 100 is in the locked state, the guide posts 622 are inserted into some of the locking holes 241. Since there are multiple guide posts 622, the rotation locking plate 620 cannot rotate relative to the locking connecting plate 240, thereby realizing the temples. 100 rotation lock. When the temple 100 needs to be rotated, the button portion 641 is pressed, and the abutting column 642 moves downward, which drives the abutting guide column 622 to also move downward, and the second spring 630 is compressed by force. When the button portion 641 continues to press downward, the abutting column 642 is inserted into the partial locking hole 241 until the guide column 622 is disengaged from the partial locking hole 241 . At this time, when the temple 100 is rotated, the lateral portion 521 of the rotating arm can rotate around the rotating locking shaft 610 , and the rotating locking disc 620 rotates together with the lateral portion 521 of the rotating arm. After the temple 100 is rotated in place, the button portion 641 is released, the second spring 630 rebounds, and drives both the rotary locking disc 620 and the rotary locking switch 640 to move upward, and the upward movement of the guide post 622 will be inserted into the other part of the locking hole 241 inside, so as to re-implement the rotation locking of the temple 100 .

Preferably, the number of the locking holes 241 in this embodiment is four, which are symmetrically distributed with respect to the rotation locking shaft 610 . The number of the abutting posts 642 and the guiding posts 622 is two respectively, and the two guiding posts 622 are simultaneously inserted into the two locking holes 241 arranged at intervals. The symmetrical distribution structure is beneficial to realize the reliable stability of the structure, and avoid the deflection of components such as the rotary lock switch 640 and the second spring 630 due to uneven force during movement.

When the two guide posts 622 are simultaneously inserted into the two spaced locking holes 241 , the AR glasses can be in a wearing working state or a hand-held working state, so that the temple 100 can be locked at a specific angle position.

As can be seen from FIG. 13 , there is a certain distance between the locking connecting plate 240 and the upper side wall 223 of the mirror frame 200 , and the button portion 641 moves between the locking connecting plate 240 and the upper side wall 223 of the mirror frame 200 .

It can be seen from FIG. 11 and FIG. 12 , among the two rotating arms 520 , the rotating arm 520 located above is rotatably connected to the mirror frame 200 through the temple rotation locking assembly 600 , and the rotating arm 520 located below is connected to the mirror frame through a common rotating shaft structure 200 turn connections. The rotation locking of the temple 100 is realized by the locking of the upper rotating arm 520 by the rotation locking assembly 600 of the temple.

The rotation axis Y1 of the temple 100 coincides with the axis of the rotation locking shaft 510 .

The lens rotation structure includes two AR lenses 400, a nose bracket 300, and a lens rotation tensioning assembly. A nose bracket hollow cavity 310 is formed inside the nose bracket 300 for installing other components. Both AR lenses 400 are rotatably connected to the nose bracket 300 , and the AR lenses 400 can rotate relative to the nose bracket 300 around the rotation axis X1 . When the AR glasses are in the wearing working state, the two AR lenses 400 are located on the left and right sides of the nose bracket 300 , referring to FIG. 1 and FIG. 2 ; when the AR glasses are in the handheld working state, the two AR lenses 400 are located on the nose bracket 300 The same side (especially the upper side or the upper side, the upper side is exemplified in this embodiment), refer to FIG. 7 . The lens rotating and tightening component is arranged in the hollow cavity 310 of the nose bracket, and is used to provide a tightening force to the AR lens 400 so that the AR lens 400 is always in close contact with the nose bracket 300, thereby improving the reliability and stability of the AR glasses.

The AR lens 400 is provided with a lens connecting plate 410, and the nose bracket 300 is provided with a nose bracket opening 330 for the AR lens 400 to be connected and inserted. The nose bracket opening 330 is preferably an L-shaped opening structure, a part is provided on the left and right side walls ( 324 , 325 ) of the nose bracket 330 , and the other part is respectively provided on the upper side wall 323 of the nose bracket/300 . On the one hand, the nose bracket opening 330 plays a guiding role for the rotation of the AR lens 400 , and on the other hand, the size of the nose bracket opening 330 limits the rotation range of the lens 400 .

As a preferred embodiment, the rotational connection between the AR lens 400 and the nose bracket 300 is realized by the following structure: a sliding groove 820 is provided in the hollow cavity 310 of the nose bracket. A second sliding shaft 810 is rotatably disposed on the lens connecting plate 410 , and the axis of the second sliding shaft 810 is perpendicular to the rotation axis X1 . The second sliding shaft 810 is movably disposed in the sliding groove 820 and can move along the sliding groove 820 . The lens rotation tensioning assembly is connected with the second sliding shaft 810 .
