What is the rear bumper fixing bracket of a car
The rear bumper fixing bracket of a car is an important structural component that connects the rear bumper to the vehicle body. It is mainly used to support and fix the rear bumper, ensuring that it plays a buffering role and disperses the impact force during a collision.
Specific functions
Youdaoplaceholder0 Support structure : Located at the bottom of the rear body of the vehicle, it firmly connects the bumper to the body through metal or engineering plastic materials to prevent loosening due to jolts during driving.
Youdaoplaceholder0 Safety protection : It can withstand part of the impact force during a collision, reducing the damage to the vehicle body and protecting the safety of the occupants at the same time.
Youdaoplaceholder0 Material selection : common metals (such as steel) or high-strength engineering plastics, taking into account both durability and lightweight requirements.
If the rear bumper of the vehicle becomes loose or damaged, the bracket may need to be replaced to restore its structural strength.
The rear bumper fixing bracket of a car (also known as the rear bumper bracket) is an important component that connects the rear bumper to the vehicle body. It mainly serves to support and fix, and at the same time provides certain protection for the rear of the vehicle.
Specific function
Youdaoplaceholder0 Support and fix the bumper
The bracket connects the bumper to the vehicle body, ensuring that the bumper can effectively absorb energy in the event of a collision and reducing the impact on the vehicle body.
Youdaoplaceholder0 protect the rear structure of the vehicle
In low-speed collisions, the frame can disperse the impact force and reduce the degree of damage to the vehicle body. During high-speed collisions, it absorbs energy through deformation, reducing the threat to the passenger compartment.
Youdaoplaceholder0 enhance overall security
As an important component of the passive safety system, the bracket works in coordination with the bumper to enhance the vehicle's crashworthiness and reduce maintenance costs.
The main function of the rear bumper fixing bracket of a car is to support and protect the bumper, and at the same time, to disperse the impact force during a collision to ensure the safety of the vehicle body. If the bracket malfunctions, it may cause problems such as loose bumpers and abnormal noises, and even affect driving safety.
Possible manifestations of the fault
Youdaoplaceholder0 Loose bumper or abnormal noise : Damaged brackets may cause the bumper to fail to be firmly fixed, resulting in abnormal noise during driving.
Youdaoplaceholder0 Collision protection capability decline : Bracket failure may weaken the protection of the vehicle body and increase the risk of accident injuries.
Youdaoplaceholder0 Risk of vehicle body structure deformation : Long-term malfunctions may cause abnormal bottom structure of the vehicle body, affecting vehicle stability.
It is recommended that any faults be repaired in a timely manner upon discovery and the damaged brackets be replaced to ensure driving safety.
The bumper bracket is a key component of the automotive passive safety system, mainly responsible for the connection and support function between the bumper and the vehicle body. Its structure consists of a support body, a guiding mechanism and a buffer device, which absorb collision energy through high-strength steel or composite materials. This component has formed a multi-dimensional technological innovation system in the field of mechanical engineering, covering patented solutions such as improving assembly accuracy and optimizing dynamic buffering performance. According to the requirements of national standards, products need to pass systematic tests and verifications such as mechanical performance and environmental adaptability.
The rear bumper fixing bracket of a car is made of high-strength steel or composite materials and mainly serves the connection and support function between the bumper and the vehicle body. Its working principle is as follows:
Structural composition
It is usually composed of three parts: the support body, the guiding mechanism and the buffer device. High-strength steel or composite materials are used to absorb collision energy.
Energy absorption mechanism
During a collision, the bracket absorbs energy through deformation, reducing the impact force on the vehicle body and providing buffering protection.
Connection method
The bumper is tightly fixed to the vehicle body through a rigid connection structure to ensure stability during driving.
