- the second support rod 44 is firmly connected to the side beam 500 of the vehicle body, and it is also convenient to load and unload the second support rod 44 and the side beam 500.
- the second support rod 44 and the side beam 500 can be connected by screw connection.
- a headlight bracket 40 according to a specific embodiment of the present application will be described below with reference to FIGS. 18 to 22 .
- the headlight 60 When the headlight 60 is installed, it is matched with the headlight bracket 40 in advance. Since it is connected to the vehicle body by fasteners, the assembly efficiency of the headlight 60 is improved.
- the vehicle 1000 has a front collision, the headlight 60 is firmly installed on the headlight bracket 40 and is surrounded by the headlight bracket 40. Since the front end surface of the collision part of the headlight bracket 40 exceeds the front end surface of the headlight 60, the anti-collision part 41 of the headlight bracket 40 will be directly impacted by the collision while the headlight 60 will not be hit. Therefore, the headlight bracket 40 plays a good protective role for the headlight 60.
- the headlight bracket 40 is an integrated bracket, the collision impact force received by the anti-collision part 41 of the headlight bracket 40 is transmitted to the support part 42, and then transmitted to the first support rod 43, the second support rod 44 and the connecting limb 45 of the headlight bracket 40.
- the first support rod 43 is subjected to the impact force and fails and breaks in the first collapse hole 431 area, absorbing the impact energy and disconnecting from the connecting frame 80.
- the second support rod 44 is subjected to the impact force and fails and breaks in the second collapse hole 441 area, absorbing the impact energy and disconnecting from the vehicle body.
- the connecting limb 45 is subjected to the impact force and fails and breaks in the third collapse hole 451 area, absorbing the impact energy and disconnecting from the lower bracket 70. In this way, the headlight bracket 40 is completely separated from the vehicle body, and because it only breaks in the weakened area, the headlight bracket 40 has a good structural strength, and moves backward with the headlight 60, further buffering the energy of the collision impact.
- a vehicle 1000 according to an embodiment of the third aspect of the present application includes a front vehicle body structure according to an embodiment of the second aspect of the present application.
- a front body structure according to the second aspect embodiment of the present application is provided, so that the headlight assembly 300 can be crushed in the z direction, so that the movement amplitude of the pedestrian's upper body toward the vehicle 1000 and the ground when impacted by the vehicle 1000 is reduced, thereby protecting the head.
- a forwardly protruding anti-collision portion 41 is provided on the front side of the headlight bracket 40, and the front end of the anti-collision portion 41 extends forward beyond the front end of the headlight 60, protecting the headlight 60 from being damaged by impact when the vehicle 1000 has a front collision, thereby reducing the cost of replacing the headlight 60 when repairing the vehicle 1000, and reducing the repair cost of the vehicle 1000.
- first and second are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as “first” or “second” may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of “plurality” is two or more, unless otherwise clearly and specifically defined.
