Problems solved by technology

However, the existing head-mounted display is very bulky, and wearing it for a long time will make it difficult for the user's cervical spine to bear, which greatly reduces the user experience.
[0003] In order to reduce weight, there are currently various designs, mainly in the following ways: one is to reduce the absolute weight, but it will affect the battery capacity and battery life; the other is to balance the weight, separate the battery from the body, and move the battery behind the head Although the force on the front and rear is balanced, the finishing weight has not been reduced; the third is weight sharing, the battery is designed on the waist, but it is very inconvenient to connect the battery and the body

Abstract

The invention discloses a head-mounted display and belongs to the technical field of visual display equipment, the head-mounted display comprises a main machine shell, a containing cavity is formed inthe main machine shell, the upper part and the lower part of the main machine shell are respectively provided with an air inlet unit and an air outlet unit which are communicated with the containingcavity, a heat dissipation fan is arranged in the containing cavity, the heat dissipation fan is located between the air inlet unit and the air outlet unit, and the air suction direction of the heat dissipation fan is from top to bottom. According to the invention, the heat dissipation fan arranged on the head-mounted display is used, the air suction direction of the heat dissipation fan is set tobe from top to bottom, and a vertical upward lifting force generated by the heat dissipation fan can offset part of gravity, so that the compression of the head-mounted display on the cervical vertebra of a user is reduced, user experience is improved, the endurance time and the use convenience are guaranteed, and the cost is not increased.

Description

technical field [0001] The invention belongs to the technical field of visual display devices, in particular to a head-mounted display. Background technique [0002] A head-mounted display is a device for displaying images and colors, usually in the form of a goggle or a helmet. The display is placed close to the user's eyes, and the focal length is adjusted through the optical path to project images to the eyes at a close distance. However, the existing head-mounted display is very bulky, and wearing it for a long time will make it difficult for the user's cervical spine to bear, which greatly reduces the user experience. [0003] In order to reduce weight, there are currently various designs, mainly in the following ways: one is to reduce the absolute weight, but it will affect the battery capacity and battery life; the other is to balance the weight, separate the battery from the body, and move the battery behind the head Although the force on the front and back is balan...
