[0002] A dashcam is an instrument that records images and sounds while a vehicle is in motion. After installing this product, it can record objects and sounds within the lens's coverage area during driving. It can also serve as evidence in traffic accidents. People who enjoy road trips can use it to record the hardships along the way. When traveling around, the time, travel trajectory, and location can be recorded in the video, which can also help prevent the inevitable staged accidents that occur in society.

[0003] Existing dashcams are usually fixed to vehicles using adhesive or suction cups via mounting brackets, and their heat dissipation relies on ventilation holes on the dashcam casing.

[0004] However, dashcams are prone to overheating when powered on and from sunlight. Relying on ventilation holes for heat dissipation is inefficient, and over time, the heat cannot be dissipated in time, which can easily lead to freezing, crashing, or even direct damage, affecting normal operation. To address this issue, a dual-cavity active heat dissipation structure for dashcams is proposed. Utility Model Content
