Description

Technical Field

[0001] This utility model relates to the field of vehicle-mounted video recorders, and in particular to a protective structure for a video recorder. Background Technology

[0002] Vehicle-mounted video recorders (also known as vehicle-mounted DVRs or vehicle-mounted digital video recorders) belong to a niche market of traditional embedded hard disk video recorders. They are a new specialized product that has emerged with the application of digital audio and video encoding technology in vehicles. While existing vehicle-mounted video recorders have adequate safety features, they still have the following shortcomings when used in harsh environments such as construction machinery, fishing boats, or tourist boats:

[0003] (1) The product is not sturdy and heavy enough. When there is a collision with another vehicle, squeezing, or being hit by flying stones or blunt objects, the vehicle video recorder is not resistant to external impact.

[0004] (2) The waterproof structure is not reliable, especially at the external lead wires and antenna head, where the waterproof strength is insufficient;

[0005] (3) The heat dissipation performance is not good enough.

[0006] To overcome the above problems and adapt to harsh environments, this solution proposes a protective structure for video recorders. Utility Model Content

[0007] The purpose of this invention is to solve the problems of existing vehicle-mounted video recorders, such as insufficient resistance to external impact, inadequate waterproofing, and poor heat dissipation in harsh environments. The specific solution is as follows:
