Description

Technical Field

[0001] The utility model relates to the technical field of virtual reality, in particular to a lens device and virtual reality equipment. Background Art

[0002] Virtual Reality (VR) technology is a computer-generated, interactive, immersive visual virtual environment proposed in the 1980s. It can generate a variety of virtual environments as needed.

[0003] In recent years, with the advancement of computing power and various types of sensors, various types of virtual reality headsets have appeared on the market. They basically consist of a display screen or mobile phone and a pair of eyepieces. The human eye sees a magnified image on the display screen through the eyepieces, while sensors detect head movements and adjust the images on the left and right displays, allowing the human eye to see a three-dimensional, interactive visual image. However, to improve the effect, most adopt a closed structure. This means that when using VR equipment, myopic users must first put on their own glasses and then put on the VR glasses, which can easily cause fatigue and inconvenience. Utility Model Content

[0041] It should be noted that if Figure 1-7 As shown, racks 12 can be respectively provided on two opposite side walls of the lens holder 11, and the lens adjustment device 3 includes two transmission assemblies 32. Each transmission assembly 32 drives the first connecting portion 15 to move up and down relative to the second shell 212 through the rack 12, and cooperates with each other to drive the lens holder 11 to move up and down relative to the second shell 212, thereby adjusting the distance between the lens holder 11 and the user's eyes.

[0042] In one embodiment of the present invention, Figure 1-7 As shown, the lens holder 11 assembly 1 also includes:

[0043] The sealing ring 14 is mounted on the outside of the first connecting portion 15 and is configured to seal the first connecting portion 15 with the second housing 212 located outside the first connecting portion 15. When the first connecting portion 15 moves up and down relative to the second housing 212, the sealing ring 14 continuously seals the first connecting portion 15 and the second housing 212, thereby keeping the entire lens assembly in a sealed state. This prevents dust from accumulating on the lens 13, further improving the clarity of VR videos viewed by users and further enhancing the user experience.

[0044] Optional, such as Figure 8 As shown, the first connection part 15 includes: a first connection part body 151; and a plurality of ridges 152 arranged in the circumferential direction of the first connection part body 151, and a groove is formed between two adjacent ridges 152; wherein, the sealing ring 14 is sleeved in the groove, and the sealing ring 14 is sleeved in the groove, which can seal the first connection part 15 and the second shell 212.
