[0002] In order to ensure that automobile exterior parts will not fail during use, it is necessary to conduct vibration tests on automobile exterior parts, which can help provide guarantees for automobile manufacturing in terms of quality reliability and identify whether there are defects in the exterior parts.

[0003] There are many structures of automobile exterior trim, such as front bumper, rear bumper, spoiler, etc. When it is necessary to perform a vibration test on automobile exterior trim, it is necessary to install the automobile exterior trim on a carrier, and then fix it on a vibration test bench. The vibration test bench is used to perform a vibration test on the automobile exterior trim to determine whether there are any problems with the automobile exterior trim and whether the functionality is complete. However, in order to simulate the effect of the automobile exterior trim being installed on the car body, the existing carrier is generally a matching part of the car body. If the vibration test is performed on the front bumper, the carrier is the front car body, and if the vibration test is performed on the rear bumper, the carrier is the rear car body. However, there are many structures of automobile exterior trim, and the existing carrier can only meet the vibration test of a single structure, and cannot carry multiple structures for vibration test at the same time. Therefore, the test cycle is long and the test cost is high. Utility Model Content
