Novel car washing device

The invention discloses a novel car washing device. The novel car washing device comprises a car washing device body and a main engine matching device, the main engine matching device is located on the outer part of the car washing device body, and first sliding rails are fixedly installed on the positions, close the upper ends, of the front end of the inner surface and the rear end of the inner surface of the car washing device body correspondingly. According to the novel car washing device, for each cleaning vehicle, the exterior contours of the vehicles are scanned through a radar, 3D datamodeling is conducted and transmitted to a mechanical arm, the car washing mode is planned by a mechanical arm CPU based on 3D modeling data, different cleaning methods for different models and different parts can be realized, the differentiated efficient cleaning and intelligent unmanned effects are achieved, fast, safe and automatic operation is achieved, meanwhile, the problem of thorough air drying after body cleaning
