Not hurting the beam is a normal accident, and hurting the beam is a big accident. Not all cars whose collision beams have been repaired or replaced are accident cars. If the damage of these parts causes serious damage to the performance of the car, it can be counted as an accident car, otherwise it will not be counted.

From the damage degree of the front anti-collision beam, we can see the impact force of the accident. When the current impact beam is only slightly deformed, it shows that the impact force only breaks through the interception range of the bumper. If the energy-absorbing box collapses and completely produces energy-absorbing effect, it means that the impact force is called. If the front impact beam is completely deformed, the impact force may seriously damage the longitudinal beam.

Judgment of accident vehicles

1. Seen from the front, the front bumper of the car is in the front. When it hits, the front bumper will deform and squeeze the bumper, and then the energy of the subsequent water pressure tank will squeeze the engine. Generally speaking, you can see the fan and water tank of the car when you start the engine. If there are signs of replacement, then continue to look at the girders on both sides of the water tank.

The cross beam extends out to fix the anti-collision beam. If you hit the front, it will be deformed, and even if it is repaired by sheet metal, it will not return to a flat appearance, because the paper will be uneven after bending. In terms of impact, the front impact beam bears a lot of force.

2. Look at the trunk at the back. When the trunk is opened, you can see where the spare tire is. That place can't be replaced but rebuilt, so it's easier to see whether there is an accident here, and some cars don't have a rear bumper, so the rear part of the car body is fragile.

3. The side is close to the door, and the door can be replaced, but the door can be seen from the chain. The bolts of the hinge are generally painted. If they are removed, they will leave traces. What problems did you think before removing the door?

There is also listening to the sound, knocking on the metal surface of different parts of the car body to see if the sound is consistent. If there is putty to repair it, the sound will be dull. This is not suitable for beginners. Beginners can buy a paint detector, with which they can intuitively see whether the car body is filled with putty.
