[0024] Specifically, if Figures 1 to 5 As shown, two lap structures are provided, and the number of front anti-collision beam brackets 4 is the same as the number of lap structures. Each front anti-collision beam bracket 4 is respectively connected to a lap structure, and the front anti-collision beam bracket 4 provides support for the lap structure. The lap structure is connected to the front anti-collision beam bracket 4 by bolts. The front end frame assembly 1 is made of plastic material, and the front end frame assembly 1 and the lap structure are integrally formed, and the lap structure extends toward the front of the front end frame assembly 1. The lap structures extend out from both sides of the front end frame assembly 1, which are fixed on the front anti-collision beam of the engine compartment of the vehicle body, and are fitted and installed with the front anti-collision beam bracket 4 to form a matching relationship in the Z direction. At the same time, the small bracket is designed as an adjustable structure in the Z direction. The structure is concise and clear, without redundant parts, and has a high space utilization rate.
