[0021] See also Figures 1 to 4 In the practical embodiment, a pair of AR glasses with adjustable pupil distance includes an AR mirror shell body 1 and two AR lenses 2. The AR mirror shell body 1 includes the main electrical components and a control unit on the AR glasses. The AR lenses 2 are the display units of the AR glasses. The AR lenses 2 are electrically connected to the AR mirror shell body 1. This is a common technology in this field, so no further explanation is given here. An I-shaped shell 3 is fixedly connected to the inner wall of the front end of the AR mirror shell body 1. A spacing adjustment mechanism is provided on the I-shaped shell 3. Two moving frames 4 are fixedly connected to the two ends of the spacing adjustment mechanism. The two moving frames 4 are symmetrically arranged on both sides of the vertical ends of the I-shaped shell 3. The two AR lenses 2 are respectively embedded in the two moving frames 4 and are detachable. If you are worried that they are not firm, you can apply some glue.

[0022] The spacing adjustment mechanism includes a micro motor 5 fixed to the inner wall of the vertical end of the I-shaped shell 3, the main shaft end of the micro motor 5 is fixedly connected to a double groove wheel 6, the inner walls of the vertical ends of the I-shaped shell 3 are rotatably connected to a transmission wheel 8 through a rotating shaft 7, the double groove wheel 6 is respectively connected to the two transmission wheels 8 through two transmission belts 9, and a circular gear 10 is sleeved and fixedly connected on the two rotating shafts 7. The racks 11 meshing with the two circular gears 10 are slidably connected at the diagonal positions of the inner walls on both sides of the I-shaped shell 3, and the ends far away from the two racks 11 are fixedly connected to a connecting block 12 slidably connected to the inner wall of the I-shaped shell 3. The side wall of the I-shaped shell 3 is provided with a first sliding opening 13, and the connecting block 12 passes through the first sliding opening 13 It is fixedly connected to the moving frame 4. When it is necessary to adjust the distance between the two AR lenses 2 to achieve pupil distance adjustment, the micro motor 5 is started to work, driving the double-grooved wheel 6 to rotate. Since the double-grooved wheel 6 is respectively transmitted to the two transmission wheels 8 through two transmission belts 9, it drives the rotating shaft 7 to rotate, and then drives the two circular gears 10 to rotate synchronously. Since the two circular gears 10 are respectively engaged with the two racks 11, at this time, the two racks 11 move in opposite directions, thereby driving the two moving frames 4 to move in opposite directions, thereby achieving pupil distance adjustment of the two AR lenses 2. It can be adjusted as needed according to different pupil distances, which is flexible and convenient, and the AR lenses 2 can be adjusted up and down synchronously. The structure is stable and the adjustment movement is stable.

[0023] like Figure 3 As shown: a positioning slider 14 is slidably connected to the inner wall of one end of the I-shaped shell 3 away from the connecting block 12, and a connecting block 15 is fixedly connected to one side of the positioning slider 14. A second sliding opening 16 is opened on the side wall of the I-shaped shell 3, and one end of the connecting block 15 passes through the second sliding opening 16 and is fixedly connected to the moving frame 4. When the moving frame 4 is displaced, the positioning slider 14 fixed to the connecting block 15 is driven to slide, which can support and stabilize the displacement of the moving frame 4.

[0024] like Figure 4 As shown: the outer wall of the rotating shaft 7 is fixedly connected to the inner wall of the through hole of the transmission wheel 8 and the circular gear 10 by welding, and the connection is firm. The circular gear 10 is located behind the transmission wheel 8 to prevent friction.

[0025] like Figure 2 As shown: the front side wall of the vertical end of the I-shaped shell 3 is detachably fixedly connected with an inspection cover 17 by bolts, so that the inside of the I-shaped shell 3 can be inspected.

[0026] like Figure 3 As shown: a rubber ring 18 is embedded between the inner wall of the moving frame 4 and the outer wall of the AR lens 2. The rubber ring 18 is fixed on the inner wall of the moving frame 4, which makes the clamping more secure and prevents damage to the AR lens 2.

[0027] like Figure 1As shown: a control switch 19 is fixedly connected to the upper side wall of the AR mirror housing body 1, and the control switch 19 is electrically connected to one end of the micro motor 5. The power supply end of the micro motor 5 and the power supply end of the AR glasses use the same power supply. The circuit involved is the existing technology and can be fully implemented by those skilled in the art. It is easy to operate and needless to say.

[0028] like Figure 1 As shown: a light blocking ring 20 is fixedly connected to the edge of the outer wall of the AR lens housing body 1 at one end close to the human eye to improve the light blocking effect.

[0029] Working principle: when it is necessary to adjust the interpupillary distance of the two AR lenses 2, start the micro motor 5 to drive the double-groove wheel 6 to rotate. Since the double-groove wheel 6 is respectively transmitted to the two transmission wheels 8 through two transmission belts 9, it drives the rotating shaft 7 to rotate, and then drives the two circular gears 10 to rotate synchronously. Since the two circular gears 10 are respectively meshed with the two racks 11, at this time, the two racks 11 move in opposite directions, and then drive the two moving frames 4 to move in opposite directions, thereby realizing the interpupillary distance adjustment of the two AR lenses 2. It can be adjusted as needed according to different interpupillary distances, which is flexible and convenient. When the moving frame 4 is displaced, it drives the positioning slider 14 fixed to the connecting block 15 to slide, which can support and stabilize the displacement of the moving frame 4, and can adjust the AR lens 2 up and down synchronously. The structure is stable and the adjustment movement is stable.
