Belt elasticity adjusting device and head wearing device

Abstract

The invention discloses a head wearing device and a belt elasticity adjusting device, and belongs to the technical field of wearable equipment. The belt elasticity adjusting device comprises a housing, a gear and an adjusting wheel, wherein the gear is mounted in the housing and is engaged with a rack on a belt; the adjusting wheel is mounted on the housing, and an elastomer is arranged between the adjusting wheel and a gear; the gear is locked to the housing in a natural state; when the adjusting wheel is rotated by outer force, the adjusting wheel can be rotated relative to the gear; the gear is unlocked, and the elastomer is deformed, after rotating by certain angle relative to the gear, the adjusting wheel pushes the gear to synchronously rotate. According to the belt elasticity adjusting device, the housing, the gear and the adjusting wheel are matched to adjust the elasticity of the belt conveniently, and thus the clamping force of a device wearing the belt can be conveniently adjusted to meet the use demands of different users.

Description

technical field [0001] The present invention relates to the technical field of wearable devices, more specifically, to a device for adjusting the tightness of a belt body, and also relates to a head-mounted device with the device for adjusting. Background technique [0002] More and more devices worn by belts appear in people's work and life, such as VR (virtual reality) head-mounted devices. Head-mounted is the main component of VR equipment, which is used to fix the HMD (head-mounted display) on the head and plays an important role in the experience of the entire VR product. At present, the main headwear styles of mainstream headwear devices include headband type, strap type, and head clip type. Strap-type headwear is low-cost, but the product experience is poor, giving people a cheap feeling. It is easy to entangle hair when wearing it, and the process of adjusting the clamping force on the head is relatively low-end and cumbersome. The clamping force of the head-clip h...

Problems solved by technology

Strap-type headwear is low-cost, but the product experience is poor, giving people a cheap feeling. It is easy to entangle hair when wearing it, and the process of adjusting the clamping force on the head is relatively low-end and cumbersome.

The clamping force of the head clip-type headwear product on the wearer's headwear depends on the size of the wearer's head circumference. If the clamping force is too large, it will cause the chuck, and if the clamping force is too small, the product will not be firmly fixed.

[0003] To sum up, how to effectively solve the problem of difficulty in adjusting the clamping force of devices such as head-mounted devices that are worn through the belt body is a problem that those skilled in the art need to solve at present.
