Physical ocean virtual simulation experiment teaching device

Abstract

The invention relates to a virtual reality head-mounted display, cervical vertebra fatigue is caused by using the virtual reality head-mounted display for a long time, and the comfort of the virtual reality head-mounted display restricts VR development. The invention discloses a physical ocean virtual simulation experiment teaching device which comprises a helmet, a rotatable support, a display screen, a lens, a rechargeable battery and a system board. The helmet and the rotatable support are adopted to form an experiment teaching device frame, the rotatable support is arranged on the front portion of the helmet, the display screen is arranged in the rotatable support, the system board and the rechargeable battery are arranged on the outer rear portion of the helmet, and the gravity centerof the whole physical ocean virtual simulation experiment teaching device is located on the cervical vertebra of a user. The gravity center of the virtual simulation experiment teaching device is located on the cervical vertebra of a user, the cervical intervertebral disc is stressed evenly, cervical fatigue is resisted, and the defects that the cervical intervertebral disc and neck muscle groupsof the user are stressed unevenly to cause lesions and the user experience is poor are overcome. And polyurethane slow-rebound block-shaped foam is internally provided with a breathable light-shielding breathable channel, so that the comfort of eyes is improved.

Description

technical field [0001] The invention relates to the technical field of virtual reality, in particular to a physical ocean virtual simulation experiment teaching device. Background technique [0002] Virtual reality technology (Virtual Reality, VR) is a computer simulation technology that simulates the environment to experience the virtual world. The display principle of the head-mounted virtual reality display device is that the left and right eyes of the person respectively obtain two images of the same object with image difference generated by the display system. image, resulting in a three-dimensional effect. Also known as a VR headset. [0003] External head-mounted display device, external microcomputer system, good user experience, independent screen, complex product structure, high technical content, but limited by the data cable, you can only move around with a laptop on your backpack, such as HTCvive and OculusRift. The all-in-one head-mounted display device, also...

AI Technical Summary

Problems solved by technology

[0005] 1. The power and video transmission lines connecting the computer and the main body of the helmet limit the range of activities that the user can move, and the limitations are relatively large

[0006] 2. You can only move around with a laptop on your backpack, and the portability of the computer is poor, which reduces the portability of the helmet;

[0007] 3. The heat dissipation function of the mobile phone is poor, and watching videos for a long time may easily cause the mobile phone to heat up;

[0008] 4. The inside of the main body of the helmet needs a built-in fan to dissipate heat, and the fan noise is relatively loud, which will easily affect the viewing effect of the video;

[0009] 5. VR glasses tend to be heavy on the front side, and the uneven force on the cervical intervertebral disc of users who use it for a long time will compress the intervertebral disc, causing poor blood flow, nerve deformation, cervical intervertebral disc hyperplasia and lesions, and at the same time, the cervical muscle group will be unevenly stressed, which is easy to occur after a long time Cause lesions, using VR glasses for a long time is the same as looking down at a mobile phone, causing uneven force on the cervical spine

In addition, VR glasses are often heavy on the front side, and are fixed on the head with a cloth strap, which may cause an unstable center of gravity and crush the face and nose. For example, an adjustable VR helmet positioning structure (CN108363207A) has a heavy front side
