Description

Technical Field

[0001] This utility model relates to the field of AR glasses technology, and in particular to an AR glasses host with a heat dissipation structure. Background Technology

[0002] AR glasses are augmented reality glasses that overlay virtual images onto real-world scenes, allowing users to experience a blend of virtual and real worlds. To reduce the weight of the device, AR glasses consist of a separate main unit and the wearable device. The processing chip, battery, and other components are designed as independent main units, minimizing the weight burden on the head. The wearable device contains a camera and a waveguide. Image data captured by the camera is sent to the main unit, where the CPU performs image fusion and enhancement before sending it back to the waveguide in the AR glasses. Users can then access the enhanced image information from the waveguide.

[0003] The AR glasses host unit integrates a processing chip and a battery. The processor inevitably generates heat during data transmission, and the battery is also prone to overheating after prolonged use. Therefore, the heat inside the AR glasses host unit needs to be dissipated in a timely manner to prevent overheating from causing malfunctions in the processing chip or battery.
