A vehicle whose anti-collision beam has been repaired or replaced is an accident vehicle. The structural parts of a car (longitudinal beam, suspension system, front and rear anti-collision steel beams, energy-absorbing box and other core frames). ) and the frame (body frame, structural parts, excluding outer covering parts) can be regarded as accident vehicles if these parts are stretched, deformed or damaged due to collision (the surface of structural parts may not be obviously damaged when they are hit, but it is likely that the damage caused by impact has spread to other parts of the frame).

Once the structural parts are partially damaged, even if they are repaired by stretching or knocking, the overall body rigidity cannot be restored. If they collide again, they are likely to "fall apart".

Extended data:

If the body cover is damaged or collided, as long as the structural parts are not damaged, even if it is repaired or replaced, it will not affect the driving safety. The hood can be understood as the "coat" of the vehicle. After the damage, it can be replaced by replacing the original parts, but the structural parts are different and cannot be disassembled and replaced casually. Once damaged, it is irreversible.

How to judge that the front of a car has suffered a serious collision should follow the order from outside to inside and from front to back, such as the method shared above. First of all, we need to check all kinds of fixing screws in the engine compartment. Any displacement or trace of screw replacement is the basis of collision. Then we need to lift the vehicle, and judge the damage degree of the vehicle head by observing the paint surface of the vehicle anti-collision beam and energy-absorbing box, whether there are traces of wrinkles or touch-up paint.
