Description

Technical Field

[0001] The utility model relates to the technical field of VR glasses, and more specifically to a pupil distance adjuster for VR glasses. Background Art

[0002] Pupillary distance refers to the distance between the two pupils, measured in millimeters. Pupillary distance is divided into binocular distance and monocular distance. Monocular distance refers to the distance measured from the center of the pupil of one eye to the midline of the bridge of the nose.

[0003] As humans grow from infancy to adulthood, the distance between their pupils increases. However, due to differences in gender, race, and body shape, the distance between the pupils of adults varies. The pupil distance of most adults is between 58-78. Male pupil distance is generally higher than female pupil distance, but the proportion of female pupil distances above 69mm is higher than that of male pupil distance.

[0004] At present, the existing VR glasses are similar to traditional glasses. The spacing of VR glasses should match the user's pupil distance, otherwise it will cause blur, visual fatigue, dizziness and other problems. Long-term wearing can lead to myopia. However, the lens distance of most existing VR glasses is fixed, so their pupil distance is fixed, which makes it inconvenient to adjust the distance between the lenses according to the pupil distance of different users, and their adaptability is poor.

The rotating assembly 21 is used to drive the moving assembly 13 to adjust the distance. The output shaft of the motor 2 rotates to drive the input sun gear 210 to rotate, the gear of the input sun gear 210 drives the three planetary gears 211 on its outer wall to rotate, the three planetary gears 211 drive the output sun gear 212 to rotate, the gear on the output sun gear 212 drives the three planetary gears 211 on its outer wall to rotate, the three planetary gears 211 at the end drive the output bracket 213 to rotate, the output bracket 213 drives the screw rod 130 to rotate, and the multiple output sun gears 212 and the planetary gears 211 rotate in coordination with each other, so as to reduce the rotation speed of the output shaft of the motor 2, so as to facilitate a more precise movement distance between the two sliders 131;

[0025] According to the above disclosure of the specific structure of the moving component 13, the moving component 13 includes a screw rod 130, the screw rod 130 is fixedly connected to the end of the output bracket 213, the outer wall of the screw rod 130 is movably connected to two sliders 131, and a lens is installed at the bottom of the slider 131. A noise reduction component 22 is fixedly connected between the outer walls at both ends of the screw rod 130 and the outer wall of the end of the input sun gear 210, and a limiting component 12 is movably connected between the two sliders 131 and the inside of the housing bracket 1. The moving component 13 is used to adjust the distance between the lenses, and the two sliders 131 on its outer wall are driven to move by the rotation of the screw rod 130, and the moving position of the slider 131 is limited by the limiting component 12 to prevent the slider 131 from rotating with the rotation of the screw rod 130. By adjusting the position distance of the two sliders 131, the distance between the lenses on the two sliders 131 is adjusted, and the pupil distance is adjusted by adjusting the lens distance;

[0026] According to the above disclosure of the specific structure of the limit assembly 12, the limit assembly 12 includes two metal shafts 122, the metal shafts 122 are movably connected between the two sliders 131 and the inside of the shell bracket 1, and a baffle 120 is fixedly connected between the two ends of the two metal shafts 122 passing through the shell bracket 1, and a plurality of screws 121 are movably connected between the baffle 120 and the end of the shell bracket 1. The limit assembly 12 is used to limit the moving position of the slider 131, by passing the two metal shafts 122 into the inside of the shell bracket 1 and connecting the two sliders 131, and fixing the position between the baffle 120 and the shell bracket 1 by rotating the screws 121, thereby fixing the baffle 120 and the metal shaft 122 on the shell bracket 1, so that the metal shaft 122 can limit the moving position of the slider 131 and prevent the slider 131 from rotating;

[0027] According to the above disclosure of the specific structure of the noise reduction component 22, the noise reduction component 22 includes two bearings 221, and the two bearings 221 are respectively fixedly connected to the outer walls at both ends of the screw rod 130, and the outer wall of the input sun gear 210 is fixedly connected with a rubber plug 220. The noise reduction component 22 is used to reduce the noise generated by the rotating structure. By installing the two bearings 221 on the outer walls at both ends of the screw rod 130, the friction and wear of the screw rod 130 during rotation are reduced by the shape design of the bearing 221 itself. At the same time, the bearing 221 uses high-performance materials to reduce the vibration and noise generated by the operation of the bearing 221. The rubber plug 220 prevents dust, debris, moisture, etc. from entering the interior of the motor 2, and at the same time reduces the vibration generated by the motor 2 during operation. The transmission to the outside of the casing is reduced, thereby reducing the interference of noise on the surrounding environment and making the motor 2 run more smoothly.

[0028] The improvement of this embodiment lies in that: the two metal shafts 122 are inserted into the interior of the outer shell bracket 1 and connected to the interior of the two sliders 131, and the position between the baffle 120 and the outer shell bracket 1 is fixed by rotating the screw 121, so that the baffle 120 and the metal shaft 122 are fixed on the outer shell bracket 1, so that the metal shaft 122 can limit the moving position of the slider 131 to prevent the slider 131 from rotating, and the input sun gear 210 is driven to rotate by the rotation of the output shaft of the motor 2, and the three planetary gears 211 on the outer wall of the input sun gear 210 are driven to rotate by the gears of the input sun gear 210, and the output sun gear 212 is driven to rotate by the three planetary gears 211, and the three planetary gears 211 on the outer wall of the output sun gear 212 are driven to rotate by the gears on the output sun gear 212, and the output bracket 213 is driven to rotate by the three planetary gears 211 at the end, and the screw rod 130 is driven to rotate by the output bracket 213, and the multiple output sun gears 212 and the planetary gears 211 cooperate with each other to rotate, so as to output the motor 2. The rotation speed of the shaft is weakened, so that the moving distance between the two sliders 131 is more precise. The two sliders 131 on the outer wall are driven to move by the rotation of the screw rod 130. The moving position of the slider 131 is limited by the limit assembly 12 to prevent the slider 131 from rotating with the rotation of the screw rod 130. The distance between the lenses on the two sliders 131 is adjusted by adjusting the position distance of the two sliders 131. The pupil distance is adjusted by adjusting the lens distance. The two bearings 221 are installed on the outer walls at both ends of the screw rod 130. The shape design of the bearings 221 themselves reduces the friction and wear during the rotation of the screw rod 130. At the same time, the bearings 221 use high-performance materials to reduce the vibration and noise generated by the operation of the bearings 221. The rubber plug 220 prevents dust, debris, moisture, etc. from entering the motor 2. At the same time, the vibration generated by the motor 2 during operation is reduced to the outside of the casing, thereby reducing the interference of noise on the surrounding environment and making the motor 2 run more smoothly.

[0029] In summary, the working principle of this solution is as follows:

[0030] The position stability between the moving component 13 and the outer shell bracket 1 is improved by the limiting component 12, wherein the limiting component 12 passes two metal shafts 122 into the inner part of the outer shell bracket 1 and communicates with the inner part of the two sliders 131, and the position between the baffle 120 and the outer shell bracket 1 is fixed by rotating the screw 121, so that the baffle 120 and the metal shaft 122 are fixed on the outer shell bracket 1, so that the metal shaft 122 can limit the moving position of the slider 131 to prevent the slider 131 from rotating, and the rotating component 21 is driven by the motor 2 to rotate inside the outer shell bracket 1, and the moving component 13 is driven by the rotating component 21 to rotate on the outer shell bracket The rotating assembly 21 drives the input sun gear 210 to rotate through the output shaft of the motor 2, drives the three planetary gears 211 on the outer wall to rotate through the gear of the input sun gear 210, drives the output sun gear 212 to rotate through the three planetary gears 211, drives the three planetary gears 211 on the outer wall to rotate through the gears on the output sun gear 212, drives the output bracket 213 to rotate through the three planetary gears 211 at the end, drives the screw rod 130 to rotate through the output bracket 213, and drives the plurality of output sun gears 212 and the planetary gears 211 to rotate in coordination with each other. The rotation speed of the output shaft of the motor 2 is weakened, so that the moving distance between the two sliders 131 is more precise. The noise reduction component 22 is used to reduce the noise during the rotation of the moving component 13 and the rotating component 21. The noise reduction component 22 is installed on the outer walls of the two ends of the screw rod 130 by two bearings 221. The shape design of the bearing 221 itself reduces the friction and wear during the rotation of the screw rod 130. At the same time, the bearing 221 uses high-performance materials to reduce the vibration and noise generated by the operation of the bearing 221. The rubber plug 220 prevents dust, debris, moisture, etc. from entering the motor 2, and reduces the noise generated by the motor 2 when it is working. The vibration is transmitted to the outside of the casing, thereby reducing the interference of noise on the surrounding environment and making the motor 2 run more smoothly. The distance between the two lenses is adjusted by moving the moving component 13, so as to adjust the pupil distance. The moving component 13 drives the two sliders 131 on its outer wall to move by rotating the screw rod 130. The moving position of the slider 131 is limited by the limit component 12 to prevent the slider 131 from rotating with the rotation of the screw rod 130. The position distance of the two sliders 131 is adjusted to adjust the lens distance on the two sliders 131, and the pupil distance is adjusted by adjusting the lens distance.
