Description

Technical Field

[0001] The present invention relates to the technical field of VR glasses, and in particular to a back-mounted VR glasses. Background Art

[0002] VR glasses, also known as VR headsets, are virtual reality head-mounted display devices. They are products that integrate multiple technologies such as simulation technology, computer graphics, human-computer interface technology, multimedia technology, and sensing technology. They are a brand-new means of human-computer interaction created with the help of computers and the latest sensor technology. The lenses in VR glasses are based on different visual fields and create different depth perceptions of the picture in the local space, forming a virtual reality visual field in the user's brain visual system. The main limiting factor of the virtual reality visual field is the lens, not the pupil. In order to obtain a wider visual field, it is necessary to shorten the distance between the user's eyeball and the lens or increase the size of the lens. VR glasses are a cross-era product that not only allows every enthusiast to experience with surprise and joy, but also deeply fascinates people because of the unknown of its birth and future.

[0003] After retrieval, a patent for invention with the publication number of CN110376746A discloses a VR glasses, which includes a housing and a wearing device. The wearing device is arranged at one end of the housing. Both ends of the housing are open structures. A sliding opening is provided at the top of the housing. A lifting block is arranged inside the housing. The lifting block blocks both ends of the housing. The inside of the lifting block is a hollow structure. A VR lens is arranged on one side of the lifting block close to the wearing device. A display device is arranged on the side of the lifting block away from the VR glasses. The lifting block is slidably connected to the housing. The lifting block can move up and down from the sliding opening. A handle device for lifting the lifting block is arranged at the top of the lifting block. Fixing devices are arranged on both sides of the lifting block, and the fixing devices are used for fixing the lifting block after it rises.

[0004] Combined with the above patent, it is found that the prior art has the following deficiencies: VR glasses in the prior art basically adopt a head-mounted structure and use multiple headbands for wearing operations at the same time. However, during long-term wearing, due to the relatively tight binding of multiple headbands and the excessive contact area between multiple headbands and the head, which causes the disadvantage of poor air permeability, it will affect the comfort of the user. Seriously, it will constrict the head and affect blood circulation, reducing the performance. Therefore, it is urgent to design a back-mounted VR glasses to solve the above problems. Summary of the Invention
