Embodiment 1

[0059] Such as figure 2 As shown, a virtual reality device pupil distance adjustment device provided by Embodiment 1 of the present invention includes: an adjustment structure, a first gear 201 , a first lens frame 202 , a second lens frame 203 and a housing 204 ; The first lens frame 202 is provided with a first rack 205; the second lens frame 203 is provided with a second rack 206;

[0060] Wherein, the first gear is coupled between the first rack and the second rack, and the adjusting structure is connected with the first rack.

[0061] In the embodiment of the present invention, as long as the adjustment structure moves, the first rack connected to the adjustment structure moves, because the first rack is arranged on the first lens frame, so the movement of the first rack will drive the first lens frame to move, At the same time, the movement of the first rack will drive the first gear coupled with the first rack to rotate, and the rotating first gear will drive the seco...

Embodiment 2

[0080] Such as Figure 7 ~ Figure 10 As shown, a virtual reality device pupil distance adjustment device provided by Embodiment 2 of the present invention includes: an adjustment structure, a first gear 201, a first lens frame 202, a second lens frame 203, and a housing 204; The first lens frame 202 is provided with a first rack 205; the second lens frame 203 is provided with a second rack 206;

[0081] Wherein, the first gear is coupled between the first rack and the second rack, and the adjusting structure is connected to the first rack.

[0082] In the embodiment of the present invention, when the user operates the adjustment structure, the first rack connected to the adjustment structure moves, because the first rack is arranged on the first lens frame, so the movement of the first rack will drive the first lens frame At the same time, the movement of the first rack will drive the first gear coupled with the first rack to rotate, and the rotating first gear will drive the...

Embodiment 3

[0094] Such as Figure 11 As shown, a method for adjusting the interpupillary distance of a virtual reality device provided by Embodiment 3 of the present invention is applied to Figure 2 to Figure 6 For any device for adjusting pupil distance of virtual reality equipment, the method includes:

[0095] S1101, receiving an instruction from a user to adjust the interpupillary distance;

[0096] Wherein, the instruction is an instruction to adjust the center distance between the first lens frame and the second lens frame when a signal from the user to press the button is received;

[0097] It can be understood that when the user watches pictures and videos through the first lens frame and the second lens frame and finds that the center distance between the first lens frame and the second lens frame is not equal to the user's pupillary distance, by pressing the In this way, the main circuit board in the pupil distance adjustment device of the virtual reality device receives an ...

Abstract

The embodiment of the invention provides a pupil distance adjustment device and method for virtual reality equipment. The pupil distance adjustment device for the virtual reality equipment comprises an adjustment structure, a first gear, a first lens frame, a second lens frame and a shell, and is characterized in that the first lens frame is provided with a first rack; the second lens frame is provided with a second rack; the first gear is coupled to a part between the first rack and the second rack, and the adjustment structure is connected with the first rack. The adjustment structure can comprise a button, a sliding block, a stepping motor, a flexible printed circuit board, a main circuit board and a power supply. The adjustment structure can comprise a roller, a second gear and a third gear. The adjustment structure, the first gear, the first lens frame and the second lens frame are packaged in the shell. By applying the embodiment of the invention, the whole adjustment system is enabled to be easy to control, and accurate pupil distance adjustment is easy to implement.

Description

technical field [0001] The invention relates to the field of virtual reality devices, in particular to a device and method for adjusting pupil distance of a virtual reality device. Background technique [0002] In recent years, various virtual reality (Virtual Reality, VR) devices have appeared on the market, among which VR head-mounted devices are the most influential. Specifically, the VR head-mounted device is a wearable device, and the head-mounted device needs to be worn by different people to ensure the comfort of wearing the head-mounted device. Anthropometry shows that there are certain differences in the interpupillary distance of people in different regions and countries. Therefore, most of the current VR headsets can adjust the interpupillary distance. [0003] The interpupillary distance adjusting device in the prior art is as figure 1 As shown, through a sliding bar 120 exposed from the housing 110, the sliding bar 120 drives the first rack 130 to move in the...
