[0002] The headlight impact test is a series of tests used to evaluate the structural integrity and functional reliability of automobile headlights when subjected to physical impact. There are two main types of impacts that headlights may encounter. The first is the impact of objects on the ground (such as stones) on the headlights caused by high-speed driving of the car. The second is the external force impact on the headlight as a whole. The purpose of the impact test is to determine the maximum impact energy that the headlight can withstand, and to improve the design accordingly to improve its strength and durability, thereby extending its service life.

At the same time, the damaged plastic parts produced by the hammering will splash around, causing unnecessary damage to the surrounding personnel. Therefore, the utility model proposes an impact test device for car lights. Utility Model Content
