Specifically, the first electromagnetic module 251 is slidably matched with the cavity wall of the accommodating cavity 223, and can be moved out of the accommodating cavity 223, so that at least part of the first electromagnetic module 251 is exposed out of the accommodating cavity 223, and the size of the head-mounted assembly 200 is reduced as much as possible during assembly, thereby being beneficial to miniaturization of equipment; at the same time, the annular space 210 may be enlarged to accommodate different user head sizes while being worn by the user.

On the basis of the above scheme, in order for the pressure sensor 290 to control the driving motor 271 to move so as to reduce the wearing pressure, for example, after assembly, the user finds that the annular space 210 is too small, when the user wears the head-mounted device 200 by head extrusion and pulling, the pressure sensor 290 on the inner side of the rear shell 240 also detects the pressure value, but the pulling force when pulling a small distance is smaller, the pressure value detected by the pressure sensor 290 is insufficient to trigger the driving motor 271 to rotate the screw 272 (to a certain value and can trigger the driving motor 271 to set by himself), so that four springs (two on each side) are provided at this time, namely, the springs are stretched, the appearance is that the first electromagnetic module 251 starts to expose the side of the body, when the user wears the head-mounted device continuously, the first electromagnetic module 251 is pulled by the middle shell 230, the four springs are also pulled to be longer and longer, the appearance is that the pressure value detected by the pressure sensor 290 of the rear shell 240 is larger and the pressure value detected by the pressure sensor 290 is larger, when the pressure value exceeds the threshold value of the driving motor 271 is started, the driving motor 271 is driven to rotate (to a certain value can be set by himself) and the maximum value is not required to be stretched by the mounting plate 273, and the springs can be completely stretched to be in a state when the maximum value is kept at a high and the maximum value is set by pushing the mounting plate 273 is reached.

When the head assembly 200 is removed, the four springs are quickly returned to the initial state, the springs are in the natural state, the pressure sensor 290 cannot detect the pressure, the driving motor 271 is immediately started to drive the screw 272 to rotate along the recycling direction, the mounting plate 273 moves reversely, the first electromagnetic module 251 is placed in the accommodating cavity 223 until the gap between the middle section and the body is zero, the appearance is shown to return to the initial state, and the front shell 220, the middle shell 230 and the rear shell 240 can be detached into the front shell 220 after the electromagnetic module 250 of the front shell 220 and the rear shell 240 is powered off, so that the accommodating space is reduced.

The present invention further provides a head-mounted display device 100, where the head-mounted display device 100 includes a display apparatus 300 and a head-mounted assembly 200, and the specific structure of the head-mounted assembly 200 refers to the above embodiment, and since the head-mounted display device 100 adopts all the technical solutions of all the embodiments, at least has all the beneficial effects brought by the technical solutions of the embodiments, and will not be described in detail herein. The display device 300 is mounted on the main body 221. The display device 300 is mounted on the main body 221, and the display device 300 is generally composed of two parts: a display screen and a lens group. The display screen is one of the most basic components of a head-mounted VR device. It is used to display images and videos of the virtual environment so that the user can experience immersive visual effects. Most of the head-mounted VR devices on the market today use OLED (organic light emitting diode) or LCD (liquid crystal display) screens that can provide high resolution and high refresh rate images, allowing the user to enjoy the experience of the virtual environment more clearly and smoothly. The lens group is one of the key components that helps the user see a more realistic, stereoscopic virtual environment. The lens group is used for refracting and projecting the image on the display screen to eyes of a user to generate a close-range amplifying effect, so that the stereoscopic impression and the depth impression of the virtual environment are displayed. Different lens group configurations and parameters will produce different field angle and focal length effects, affecting the final visual experience,

in order to increase the visual comfort of the user, the display and lens assembly occupy a significant volume and weight in the head-mounted VR device, and therefore require reasonable distribution and design to ensure that the entire device can be worn on the user's head in a balanced, comfortable manner. The eye distance and vision level of different users are different, so appropriate adjustment and variable focus functions may be provided in the head-mounted VR device to improve the user's visual fitness and comfort. The VR device is easily damaged by long-term use, so that anti-glare and blue light filtering functions can be added to the display apparatus 300 to protect the eyes of the user.

The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, and all equivalent structural changes made by the description of the present invention and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the invention.
