Description

Technical Field

[0001] The utility model belongs to the technical field of display devices for unmanned vehicles, and in particular relates to a display device for roadside perception of an unmanned vehicle in vehicle-road collaboration. Background Art

[0002] Unmanned vehicles, also known as self-driving cars, computer-driven cars or wheeled mobile robots, are intelligent cars that achieve unmanned driving through computer systems. They rely on the collaborative efforts of artificial intelligence, visual computing, radar, monitoring devices and global positioning systems to allow computers to automatically and safely operate motor vehicles without any active human operation.

[0003] Currently, most of the self-driving cars on the market are assisted driving, and the driver is required to sit in the main driving seat to perform certain operations. At this time, the display screen on the car may have poor heat dissipation after working for a long time, which will affect its service life. Utility Model Content

[0024] The filter screen 42 is circular in shape as a whole, and is made of aluminum alloy. The filter screen 42 made of aluminum alloy has a good texture and is not easily rusted or damaged.

[0025] The rotating gear 46 is an incomplete gear, and the teeth on the rotating gear 46 match the teeth on the gear rod 413. When the rotating gear 46 rotates and meshes with the gear rod 413, it drives the gear rod 413 to move downward.

[0026] The bristles of the cleaning brush 412 are made of nylon, and the bristles of the cleaning brush 412 fit the surface of the filter 42. The nylon bristles are not easy to generate static electricity during friction. When the cleaning brush 412 moves up and down, its bristles will clean the surface of the filter 42.
