Description

[0002] At present, the dashboard assembly and auxiliary instrument assembly of passenger cars, that is, the interior and exterior decoration of the car also need to be able to resist external impact to a certain extent. Therefore, its low-temperature impact resistance needs to be defined during the development process of interior and exterior decoration parts. After the impact is completed, observe whether there are cracks, damage and color changes on the surface of the sample.

[0067] In some implementation scenarios, combined with Figures 1 to 3 As shown, the specific use process of the falling ball impact device provided in the embodiment of the present application is as follows:
