Embodiment Construction
[0050] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0051]It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.
[0052] In addition, if there are descriptions involving "first", "second" and s...

The invention discloses a head-mounted adjusting system and a head-mounted device. The head-mounted adjusting system comprises a shell, a gas driving piece and a switch piece, a sealing cavity is formed in the shell, and the sealing cavity is filled with a pressure gas; one end of the gas driving piece is provided with a driving part which is sealed with the sealing cavity and is in sliding fit with the sealing cavity, the driving part divides the sealing cavity into a first cavity and a second cavity which are located on the two sides of the driving part, the areas of the two sides of the driving part are different, and the other end of the gas driving piece is used for being connected with a rope belt; and the switch piece is used for enabling the first cavity and the second cavity to be communicated and closed. According to the technical scheme provided by the invention, the two cavities are communicated by controlling the switch piece so that the pressure intensity is the same, the areas of the two sides of the driving part are different, the driving part moves, the switch piece is closed and the air pressure on the two sides of the driving part is in a balanced state due to the pressure difference generated by acting on the two sides of the driving part, and the air driving piece is fixed relative to the shell; and the pneumatic head-mounted adjusting system is simple in adjusting structure and free of noise.
Description
technical field [0001] The invention relates to the field of electronic products, in particular to a head-mounted adjustment system and a head-mounted device. Background technique [0002] At present, there are mainly two types of VR headset adjustment systems: strap adjustment system and gear adjustment. Among them, the strap-type adjustment system relies on the use of elastic bands and Velcro. After adjusting the VR position, tighten the elastic bands and fix them with Velcro. The gear type is the main form of the current high-end VR head-mounted adjustment system. Through the two racks and the ratchet meshing transmission, the two racks are locked in the forward direction and self-locked in the reverse direction. [0003] There are some defects in the current mainstream strap-type adjustment system and gear-type VR rear head-mounted adjustment systems. Among them, the strap adjustment method has disadvantages such as insufficient locking force, easy loosening, and decre...
