What is the rear door anti-collision plate of a car
The rear door anti-collision plate of a car is a safety protection device installed at the rear door. It is mainly used to reduce the impact force during a side collision of the vehicle, protecting the structure of the car door and the safety of passengers.
Structure and Function
Rear door anti-collision plates are usually made of high-strength materials such as steel. They reduce the degree of deformation of the door by distributing the impact force, thereby minimizing the harm to passengers. Some models also incorporate energy-absorbing designs to absorb energy through structural deformation during collisions.
Classification and Location
According to the body structure, it can be classified into three types: front anti-collision beam, side anti-collision beam (door anti-collision bar), and rear anti-collision beam. The rear door anti-collision plate is part of the side anti-collision structure and is usually located in the inner or outer edge area of the rear door.
The main function of the rear door anti-collision plate of a car is to reduce the impact force when the car door colliding, lower the noise and collision risk when the door is closed through a buffer design, and at the same time protect the car paint and passenger safety.
Specific functions
Youdaoplaceholder0 buffer protection
Anti-collision plates are made of elastic materials such as rubber. When the car door is closed, they act as a buffer, reducing the noise and impact force generated by direct contact of metal parts, and preventing the car door from deforming or the car paint from being damaged.
Youdaoplaceholder0 wide adaptability
Most anti-collision plates adopt a snap-on fixed design, which can be adapted to the rear door structure of different vehicle models. They are easy to install and have high stability. For example, the best-selling products on Taobao can be adapted to the rear doors of various box trucks.
Youdaoplaceholder0 enhance security
The rear anti-collision structure of some high-end models adopts a zoned design: the area close to the passenger uses high-strength steel (1500MPa), which can withstand significant impacts. Use ordinary steel away from the passenger area to reduce maintenance costs in low-speed rear-end collisions.
The malfunction of the rear door anti-collision plate of a car may be caused by the following reasons:
Common causes
Youdaoplaceholder0 Component damage : The anti-collision plate itself has manufacturing defects or physical damage (such as deformation due to impact), and needs to be inspected and replaced.
Youdaoplaceholder0 Installation issue : The position was not correctly calibrated or fixed during installation, resulting in the anti-collision plate failing to function properly.
Youdaoplaceholder0 line fault : The sensor or connection line of the anti-collision plate is damaged, which may affect signal transmission.
Solution
Youdaoplaceholder0 Check the condition of the anti-collision plate : observe if there is any obvious deformation, damage or misalignment during installation.
Youdaoplaceholder0 Check the line connection : confirm that the line between the sensor and the control module is not loose or corroded.
Youdaoplaceholder0 Professional maintenance : It is recommended to have the system inspected and calibrated at a 4S store or a professional maintenance institution.
The repair method for the damaged rear door anti-collision plate of a car should be selected based on the degree of damage:
Minor damage treatment
If there are only scratches or small areas of damage, you can use glass glue or double-sided tape to stick at fixed points (such as the installation position of the car door sealing strip). When operating, avoid applying glue over a large area. After the glue is completely dry, clean up the excess glue.
Repair of depressions or cracks
Youdaoplaceholder0 Small dents : You can try to restore them with a suction cup tool or retain the original paint through sheet metal repair.
Youdaoplaceholder0 Extensive cracking : Special glue should be used to apply patches or new anti-collision strips should be replaced. Pay attention to the color matching issue.
It is recommended to contact professional maintenance personnel to handle complex damages to avoid potential safety hazards caused by self-repair.
The anti-collision devices installed behind the door are usually called door stops , floor stops or anti-collision stickers , and their specific functions and application scenarios vary.
The main types and functions of the anti-collision device behind the door
Youdaoplaceholder0 door stop .
Youdaoplaceholder0 function : Fix the door by magnetic force or mechanical structure to prevent it from closing accidentally due to wind or touch, and at the same time avoid the door hitting the wall.
Youdaoplaceholder0 Installation location : Usually installed on door panels or walls, it is divided into two forms: wall-mounted and floor-mounted.
Youdaoplaceholder0 applicable scenarios : It is suitable for scenarios where door panels need to be fixed for a long time, such as bedroom and living room doors, etc.
Youdaoplaceholder0 sucks .
Youdaoplaceholder0 function : Fix the door to the ground by means of clips or magnetic devices to prevent direct collision between the door and the wall.
Youdaoplaceholder0 Installation location : It needs to be installed on the ground at a certain distance from the wall.
Youdaoplaceholder0 Precautions : Not applicable to bathrooms or floor heating areas, may damage the waterproof layer or floor heating pipes.
Youdaoplaceholder0 anti-collision sticker .
Youdaoplaceholder0 function : pasted at the contact point between the door and the wall, it buffers the impact force through soft materials (such as silicone or soft rubber), reducing noise and wall damage.
Youdaoplaceholder0 Installation position : Directly adhere to the back of the door handle or the contact point on the wall.
Youdaoplaceholder0 Advantages : No need for drilling, suitable for temporary use or renting houses, and can also be used in scenarios such as cabinet doors.
Youdaoplaceholder0 selection suggestion
Youdaoplaceholder0 door suction/floor suction : suitable for scenarios where the door leaf needs to be fixed for a long time, it offers greater stability.
Youdaoplaceholder0 anti-collision stickers : suitable for those who pursue convenient installation, silent effect or avoid wall damage.
