Description

Technical Field

[0001] The utility model relates to the technical field of carriage testing, in particular to a water spraying test bench for a carriage. Background Technique

[0002] With the progress of society, automobile transportation is developing towards the direction of rapidity, accuracy and safety, which leads to an increasing demand for carriages. In order to produce qualified carriages, since an aluminum alloy carriage is formed by welding and splicing multiple aluminum alloy plates, and due to its relatively thin wall thickness, problems such as welding through or incomplete welding are likely to occur during welding. Therefore, it is necessary to test its waterproof performance.

[0003] The prior art proposes that a waterproof performance testing device for a lightweight aluminum alloy carriage disclosed in Chinese Patent [Application No. CN201721098906.7] includes an inverted U-shaped device main body formed by connecting pipelines. Both ends of the inverted U-shaped structure of the device main body are closed structures, and a water inlet connected to a water supply pipeline and communicating with the inside of the device main body is provided on the device main body. A plurality of water spraying holes communicating with the inside of the device main body are arranged on the inner side surface of the inverted U of the device main body. Although this patent can push the device main body to one side of the test platform by rotating the rotating fixed end of the device main body and sliding the universal wheels at the other end of the device main body, which is simple and convenient, and occupies a small space position and saves manpower and material resources. However, there are certain defects in the use of the above patent. For example, carriages are all provided with a door, and the closing part of the door is generally waterproofed with a sealing strip. In actual situations, on rainy days, there is often wind, so that the rain does not fall vertically. The above patent cannot simulate the waterproof effect when the rain does not fall vertically.
