It can be understood that the front impact beam body 1041 and the two front impact beam connecting portions 1042 can both be hollow beams, thereby reducing The weight of the vehicle as a whole reduces the impact force generated by the vehicle during the collision, and the front impact beam 104 is more easily deformed to absorb energy when the vehicle collides, thereby protecting the integrity of the cockpit and ensuring the safety of the personnel inside the vehicle.

Specifically, as shown in FIG. 8 , a reinforcing rib 10411 may be disposed in the front impact beam body 1041 to increase the rigidity of the front impact beam body 1041 . The reinforcing ribs 10411 may be multiple, and each reinforcing rib 10411 may be Extending in the left-right direction, and each reinforcing rib 10411 can connect the upper surface and the lower surface of the inner wall of the front impact beam body 1041.

In some alternative embodiments, the body frame assembly 1000 can each be a lightweight alloy frame, ie, the nacelle frame 100, the cockpit frame 200, and the luggage compartment frame 300 can each be a lightweight alloy member, thereby being available in the vehicle Maintaining a high rigidity and anti-collision performance reduces the weight of the body frame assembly 1000, thereby reducing the weight of the vehicle.

In some specific embodiments, the body frame assembly 1000 can be an aluminum alloy frame, ie, the nacelle frame 100, the cockpit frame 200, and the luggage compartment frame 300 can each be an aluminum alloy piece such that the nacelle frame 100, the cockpit frame Both the 200 and the luggage compartment frame 300 can be extruded through aluminum profiles of different cross sections and then welded or riveted. The body frame assembly 1000 thus has a low cost, is simple to form, and has good corrosion resistance.
