Description

Technical Field

[0001] The utility model relates to the technical field of car washing simulation tests, in particular to a simulated car washing test device. Background Art

[0002] It is essential to wash a car after use, but washing a car, especially using an automatic car wash machine, will cause a certain degree of scratches on the car paint surface. Therefore, it is necessary to measure the scratch resistance of the sample (test plate) coating during the automobile manufacturing process, thereby determining the process and process parameters of the coating system for automobile exterior parts.

[0003] A search revealed patent publication number CN217359447U, which discloses an automatic car wash simulation test device. The device consists of a platform moving mechanism, a brush rotating mechanism, a nozzle spraying mechanism, and a test bench. During cleaning, a test object is placed on the platform moving mechanism, which moves the object, scrubbing it with a brush, and spraying it with water. However, the device cannot spray a well-proportioned cleaning solution, resulting in an incomplete simulation. Furthermore, the platform moving mechanism is located on the test bench, making it difficult to collect the wash water, which can easily affect the on-site environment. Therefore, further improvements are needed. Utility Model Content
