Head strap used for head-mounted VR device and processing method thereof, and VR device system

Abstract

The invention discloses a head strap used for a head-mounted VR device and a processing method thereof, and a VR device system. A strap main body and an emitted hook fastener arranged on the strap main body are included. The strap main body comprises a main strap and two side straps on the two sides of the main strap. The main strap comprises at least one strap component which is in a sealed stereo annular shape or an egg shape, and an opening is formed in a middle portion. One end of each side strap is arranged above the two sides of the main strap, and the other end is provided with the emitted hook fastener connected to the VR device. Compared with an existing VR device fixing device, the head strap has the advantages of convenient and stable wearing and light weight. And a production technology is simple and cost is low. Compared with the prior art, a headless strap uses a rigid skeleton and an elastic composite high-density fabric composite material is selected so that wearing convenience is realized; and a low-elastic composite material is used to replace a rigid component so as to achieve a support function, deformation is not easy to generate and wearing is comfortable at the same time, and the strap is ventilated and achieves the exhaust of moisture.

Description

technical field [0001] The invention relates to the technical field of VR equipment system accessories, in particular to a headband for head-mounted VR equipment, a processing method thereof, and a VR equipment system. Background technique [0002] With the continuous advancement of science and technology, the technology and application of head-mounted display systems represented by virtual reality (VR, Virtual Reality) are becoming more and more mature. Its unique wide-angle spherical field of view, head motion perception, and real-time interaction , to bring users a three-dimensional immersive experience in the senses of the virtual world. [0003] The head-mounted VR display system needs to be fixed on the head through a fixing device, so that the optical lens and / or the screen are placed directly in front of the wearer's eyes. The VR device contains a multi-axis motion sensor (partly provided by a smartphone) that senses head movement, and the sensor can adjust the visu...

Problems solved by technology

This fixation device has the following problems: (1) the first strap is located at the center of the back of the head, and under the action of the upward pulling force applied by the second strap and the inertial force of head movement, the first strap is easy to slide up, resulting in a decrease in comfort Or the VR device is not stable to wear, or even slips down; (2) The adjustment of the strap is inconvenient; (3) The strap is made of conventional elastic webbing, which will cause elastic degradation after long-term wearing, resulting in a short service life

The advantage of this fixing device is that: the helmet is made of 3D three-dimensional rigid material, which is convenient to wear, but there are also the following problems: (1) the main body of the helmet (the part not including the VR equipment is the main body of the helmet) is an injection-molded plastic part, which is heavy, It will cause a sense of weight on the wearer's head and cervical spine, which is likely to cause fatigue and affect the experience; (2) The inner surface of the rigid plastic helmet needs to add additional flexible cushioning materials, and the process is complicated; (3) In order to achieve adaptability, The helmet is equipped with a complex mechanical adjustment mechanism to adjust the size of the helmet, the structure is complicated, it is inconvenient to use, the reliability is poor, and the cost is high
