Where's the back bar frame？
The rear bar frame is mainly composed of anti-collision beam and small bracket, and the anti-collision beam is the core part. Anti-collision beams are designed to absorb collision energy in the event of a collision, thereby mitigating damage to the vehicle body. It usually consists of a main beam and an energy absorption box, which can effectively absorb energy in low-speed collisions to protect the vehicle and passengers. In addition, the rear bumper also includes a number of small brackets that help secure and support the bumper housing, ensuring that it plays its proper protective role in a collision. Together with the anti-collision beams, these brackets form the backbone of the rear bar, ensuring its important role in vehicle safety.
Metamorphosis in the posterior barre
In a car crash, the bumper is easily damaged, and one of the common problems is the deformation of the inner bone of the rear bumper. So how do you fix this deformation?
Usually, the deformation of the rear bumper can be restored to its original shape. Here are two fixes:
The first method is to use the principle of softening the plastic by heat, and heat the deformed part with hot water to restore it. This method requires hot water to be poured on the deformed part, so that the plastic is softened by heat, and then immediately cooled with cold water to allow the rubber to shrink and recover. However, this method is only suitable for slight deformation.
The second method is to use the concave repair tool to prop up the deformed bumper to achieve the purpose of repair. This method requires a dent repair tool, and the cost is much lower than the repair cost of the 4S shop. Dent repair tools can prop up and repair dents to restore the bumper to its original state.
The above two methods are more suitable for the general bumper deformation problem, and help the owner to repair the bumper deformation problem without going to the 4S store. Whether it is a dented front bumper or rear bumper, be careful when repairing. If the individual can not repair, we can send to the local 4s shop repair and maintenance.
In addition, when the bumper is hit, it needs to be replaced or repainted according to the specific situation. If the crack area is small, it can be repaired by welding. If it exceeds repair standards, it needs to be replaced. If the metal bumper cracks, whether it is welding or painting, it needs professional tools and excellent technology. Usually, it needs to be repaired in the 4S shop, and personal repair cannot meet the requirements.
The car bumper is a safety device that absorbs and slows down the external impact force and protects the front and back of the body. The front and rear bumpers of cars are made of plastic and are called plastic bumpers. Automotive plastic bumpers are generally composed of three parts: an outer plate, a buffer material and a beam. The outer plate and the buffer material are connected to the beam, which is stamped into a U-shaped groove with cold-rolled plate. The outer plate and cushioning material provide protection.
