Description

Technical Field

[0002] VR glasses are a type of glasses that block the user's vision and hearing from the outside world and guide the user to feel like they are in a virtual environment. The display principle of VR glasses is that the left and right eye screens display the left and right eye images respectively. After the human eye obtains this different information, a sense of three-dimensionality is created in the mind. As a new technology that has emerged this year, VR glasses have gradually entered public life.

[0003] In the prior art, for example, Chinese patent publication number CN207096568U discloses a device for adjusting the pupil distance of VR glasses, including a VR glasses body, an adjustment mechanism and a connecting mechanism, the VR glasses body includes a left eyeglass frame, a right eyeglass frame and a bracket, the left eyeglass frame and the right eyeglass frame are used to install VR lenses, the adjustment mechanism includes a knob, the knob is respectively connected to the left eyeglass frame and the right eyeglass frame through the connecting mechanism, and the movement of the connecting mechanism is driven by the knob to adjust the relative distance between the left eyeglass frame and the right eyeglass frame.

[0004] However, the device can only adjust the left and right eyes together, moving them away or closer together, but cannot adjust one eye at a time. The pupil distance of each user wearing VR glasses is different, and the pupil distance of different people may be different. When the face shape and pupil distance are different, it is necessary to adjust the position of a single pair of glasses to increase the user experience. In view of this, we propose a VR glasses with independent pupil distance adjustment. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides a VR glasses with independently adjustable pupil distance, including a fixing plate and a connecting rod, the surface of the fixing plate is fixedly connected to a fixing frame, the inner cavity of the fixing frame is provided with a plurality of threaded rods, the end of the threaded rod away from the connecting rod is provided with a plurality of first ball-type one-way bearings, the end of the threaded rod close to the connecting rod is provided with a second ball-type one-way bearing, the side of the second ball-type one-way bearing away from the threaded rod is rotatably connected to a first sun gear, the surface of the threaded rod is rotatably connected to a first output shaft and a second output shaft, the surfaces of the first output shaft and the second output shaft are both provided with a plurality of reciprocating grooves, and the sides of the first output shaft and the second output shaft away from the first sun gear are rotatably connected to the first ball-type one-way bearing.

[0007] As a further improvement of the present technical solution, a sliding shaft is provided at the bottom of the threaded rod, a sliding block is movably connected to the surface of the sliding shaft, a groove wheel slider is fixedly connected to the top of the sliding block, a first eye frame and a second eye frame are provided on the side of the sliding block away from the first sun gear, the size of the groove wheel slider fits closely with the reciprocating groove, and the groove wheel slider is located in the inner cavity of the reciprocating groove and is movably connected to the reciprocating groove.

[0008] As a further improvement of the technical solution, the first sun gear is rotatably connected to a fixed component on the side away from the threaded rod, the bottom of the fixed component is rotatably connected to a second sun gear, and the first sun gear and the second sun gear are meshed with each other and are rotatably connected.

[0009] As a further improvement of the technical solution, a plurality of reduction gears are arranged at the bottom of the second sun gear, the bottom of the reduction gears is rotatably connected to a micro motor, and the bottom of the micro motor is fixedly connected to the connecting rod.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] The VR glasses with independently adjustable interpupillary distance use a motor and a reduction gear to drive the second sun gear to rotate, thereby driving the first sun gears on both sides to rotate, and then cooperate with a ball-type one-way bearing to achieve independent movement and adjustment on both sides. The ball-type one-way bearing contains multiple balls, which are placed in an inclined groove. When the outer ring rotates in one direction relative to the inner ring, the balls roll along the inclined groove and allow free rotation; when trying to rotate in the opposite direction, the balls are stuck in the inclined groove and prevented from rotating. The design of the ball-type one-way bearing makes the adjustment mechanism compact and occupies little space, and does not affect the overall design and wearing comfort of the glasses. The use of a micro motor and a reduction gear ensures the accuracy and stability of the interpupillary distance adjustment. The device uses a ball-type one-way bearing to achieve independent adjustment of the interpupillary distance of the left and right eyes to adapt to the differences in interpupillary distance of different users, providing a more comfortable and personalized virtual reality experience, thereby solving the problem of being unable to adjust one interpupillary distance alone.

[0024] See also Figure 3 and Figure 4 As shown, further, the first sun gear 12 is rotatably connected to a fixing component 11 on one side away from the threaded rod 24. The fixing component 11 is used to fix the first sun gear 12 and the second sun gear 33 to ensure the stability of the gear position. The bottom of the fixing component 11 is rotatably connected to the second sun gear 33. The first sun gear 12 and the second sun gear 33 are meshed with each other and are rotatably connected.

[0025] See also Figure 3 As shown, specifically, a plurality of reduction gears 31 are arranged at the bottom of the second sun gear 33, and a micro motor 32 is rotatably connected to the bottom of the reduction gear 31. The reduction gear 31 and the micro motor 32 provide a power source, and the speed is reduced and the torque is increased through the reduction gear 31, so as to accurately control the pupil distance adjustment.

[0027] In summary, the working principle of this scheme is as follows:

[0028] First, the micro motor 32 cooperates with the reduction gear 31 to drive the second sun gear 33 to rotate clockwise, and the rotation of the second sun gear 33 drives the first sun gear 12 on both sides to rotate. At this time, the threaded rod 24 connected to the side of the first sun gear 12 will also drive the first output shaft 21 and the second output shaft 22 on the surface to rotate accordingly, because the first output shaft 21 and the second output shaft 22 are respectively provided with the first ball-type one-way bearing 23 and the second ball-type one-way bearing 26 on both sides, and the first ball-type one-way bearing 23 and the second ball-type one-way bearing 26 contain a plurality of balls inside, which are arranged in an inclined groove, so when the outer ring rotates in one direction relative to the inner ring, the balls roll along the inclined groove, allowing free rotation; When trying to rotate in the opposite direction, the ball is stuck in the inclined groove, preventing rotation. Therefore, when the first output shaft 21 rotates, the second output shaft 22 will not rotate. Since a reciprocating groove 27 is provided on the surface of the first output shaft 21, and a grooved slider 25 is provided in the inner cavity of the reciprocating groove 27, when the first output shaft 21 rotates, the reciprocating groove 27 will drive the grooved slider 25 to move toward the first ball-type one-way bearing 23. When the grooved slider 25 drives the sliding block 13 to reach the end point of the sliding shaft 16, it will move back along the original path under the guidance of the reciprocating groove 27. The surface of the sliding block 13 is provided with a first eye frame 14, thereby achieving the effect of adjusting the pupil distance of a single side. The method for adjusting the second eye frame 15 is to rotate the micro motor 32 counterclockwise.
