Description

Technical Field

[0001] The utility model relates to the technical field of car washers, in particular to a tunnel type car washer anti-rear-end collision device. Background Art

[0002] As the living standards of the whole society continue to improve, cars have gradually entered thousands of households, the number of cars has increased sharply, and people have paid more and more attention to the daily maintenance of cars. Many companies specializing in car services have appeared in the market. Car washing is one of the most common maintenance items for cars. Many gas stations and car shops will provide free car washing services to attract customers. In order to save labor costs and improve car washing efficiency, gas stations and car shops generally use tunnel car washing machines to achieve automatic car washing.

[0003] During the use of existing tunnel car washers, it is generally necessary to manually control the distance between two vehicles, which is inconvenient to control by oneself. When human errors occur in operation, rear-end collisions are prone to occur. At the same time, some devices that can control the distance between vehicles with a barrier rod have a relatively simple barrier rod structure. When the driver makes an operating error, the barrier rod will be hit and damaged. Utility Model Content
