Description

Technical Field

[0001] This application relates to the technical field of heat dissipation structures for head-mounted devices, and specifically relates to a head-mounted device. Background Art

[0002] Currently, in the VR glasses industry, due to the limited internal space of the glasses, heat dissipation is a technical point that is relatively difficult to overcome. If the heat dissipation effect is not good, the temperature of the VR glasses will be too high during normal use, the head will be hot, and the eyes will feel stuffy, causing discomfort to the user and affecting the human-machine experience.

[0003] Due to the large overall power consumption of VR glasses products, conventional natural heat dissipation is difficult to solve the heat dissipation problem, and often the air-cooling method is used to solve the heat dissipation problem of the chip. The common heat dissipation form is that the outside cold air enters from the air inlet on the outer shell, is inhaled by the fan, takes away the heat of the chip, and then directly flows to the outside from the air outlet. However, both the air inlet and the air outlet in the conventional technical solution are set on the outer side of the outer shell, which cannot solve the problem of stuffiness in the eyes and face. Summary of the Invention

[0004] An embodiment of this application provides a head-mounted device, which includes: an outer shell, a display component, a main control board, and a heat dissipation fan; the outer shell forms an accommodation space, the main control board and the heat dissipation fan are arranged in the accommodation space, and the display component is embedded in the outer shell; the outer shell is provided with an air outlet and a first air inlet, the air outlet is arranged corresponding to the air outlet channel of the heat dissipation fan, and the first air inlet is arranged adjacent to the display component.

[0005] The head-mounted device provided by the embodiment of this application can solve the problem of stuffiness in the eyes and face when the user wears the head-mounted device by setting the air inlet for heat dissipation inside the mask, improve the comfort, and further enhance the user experience.
