Small accidents have no effect on rear-end collision. Replace the rear bumper and cut the rear apron at most. At most, it is a fine glue that should be rust-proof after replacing the rear apron.
A bigger rear-end collision will involve cutting or sheet metal rear longitudinal beam, and this kind of car is an accident car. After this kind of car is repaired, first of all, the second-hand preservation rate will drop sharply, which means that your car will be much cheaper to sell than the original car of the same age. Second, the balance of your car will drop sharply. In the case of high-speed driving over pits and hurdles, there will be a small tail flick, which is more dangerous.
No matter how big the rear-end collision is, it will hurt the bracket of the car, that is, the chassis of the car is hung up. This is the case that my relatives are sharp and round. What's it like to drive a car with a broken bracket? I feel that the two wheels at the back are out of sync with the two wheels at the front. More than 300,000 cars have to fine-tune the steering wheel at high speed, so the body is erratic when overtaking, and my relatives drove the car out of the sharp world at a low price on my suggestion.
Therefore, a car with a serious rear-end collision will seriously affect our daily use. Please choose carefully.
When the vehicle is driving on the road, it is rear-ended for various reasons. However, most car owners pay too little attention to the maintenance of rear-end collision, thinking that there are few important accessories behind the car, so as long as it does not affect the use, they will not pay attention to the details of maintenance. In fact, this is wrong! You need to take a closer look. Is it really fixed?
Many vehicles were rear-ended. It didn't look as serious as it felt at the time. In fact, you are wrong, because the cushioning elasticity of the rear bumper may only make you see a little tear in the paint of the bumper. When you remove the rear bumper, you will find that the rear anti-collision beam (some even have no anti-collision beam) has been sunken, the spare tire slot in the trunk has been deformed, and the reversing radar will be broken ... These places need careful repair and treatment!
The quality of the repair results depends entirely on the sense of responsibility of the employees in the repair shop. Do you think that if you fix it, you will really fix it? Of course, it's a real repair. The details and rust prevention are very good. I don't think it will make any difference if the car drives! But if the details are not done well, it will be exposed after a long time!
I have met many car owners who have been rear-ended, and think that they have found many sequelae when they change the light bulb after car washing or maintenance: there will be a small amount of water in the trunk after car washing, more and more dust in the trunk, and more and more noise coming from behind. Mud accumulates at the joint between the taillight and the car body, the anti-collision beam is corroded, the joint between the rear bumper and the trunk is too large, and the trunk cover is difficult to replace ...
It is recommended that car owners repair and solve these problems in advance once they find them!
The master who makes sheet metal has a saying: it is better to repair a tail than to repair ten heads. The meaning of this sentence is that the tail Xiu Yuan is more complicated than the previous one. The reason is actually very simple. The rear sheet metal parts are repaired by welding, and the matching of sheet metal parts is time-consuming. Unlike the front of the car, which is mainly fixed by bolts, the rear of the car is time-consuming and thankless to repair, and the sheet metal work is taboo, especially the rear of the car. Once the welded sheet metal parts are reworked, it is almost impossible to start work.
What I said above means that the rear sheet metal part is mainly welded, so it is ok not to cut or change it. Once it is cut and replaced, no matter how it is repaired, it is far from the original car. And with the passage of time, because the construction technology can't be compared with the original factory, the welding conditions and rust prevention measures are even more different. Corrosion, abnormal sound and lax switch will greatly increase the probability of water leakage and reduce the strength!
It doesn't matter if there is a little accident. After repair, the repair shop must be required to carry out anti-rust treatment on the welding parts to avoid rust and wear after driving for two or three years, because the coating on the surface of the steel plate disappears after high temperature. Rust prevention after repair is generally ineffective.
Check whether there is rain leakage and whether the trunk switch is unblocked.
If the internal bumper is not damaged, there will be no impact and the safety strength will not be affected.
That depends on how serious your rear-end collision is.
