What is the rear door anti-collision strip of a car
The rear door anti-collision strip of a car is a rubber or plastic buffer device installed on the edge of the rear door, mainly used to reduce the damage to the vehicle body caused by scratches when the vehicle is parked.
Material and Function
It is usually made of rubber or natural rubber and belongs to the exterior parts of the vehicle body. It reduces the risk of damage to the doors and surrounding parts caused by small-scale collisions through its buffering effect.
Installation location
It is mainly installed at the corner of the car door and the front and rear bumpers. Some models may use adhesive or snap-on installation.
The main function of the anti-collision strip on the rear door of a car is to prevent the door from slightly scraping against surrounding objects when it is opening or closing , providing a buffering and protective effect, and at the same time reducing abnormal noises from the door. The following is the specific explanation:
Protective effect
The anti-collision strips are made of rubber or TPU material, which can effectively buffer the contact between the car door and adjacent vehicles or obstacles, avoiding damage to the paint surface caused by excessive force when opening the door. Especially provide additional protection for vulnerable parts such as the corners of car doors.
Material properties
Most products are made of soft TPU or rubber, which are wear-resistant and weather-resistant, and can withstand daily exposure to wind and sun. The black design can maintain the overall beauty of the vehicle body and avoid visual abruptness.
Installation features
No glue is needed for fixation. It can be directly pasted and is easy to operate. But it should be noted
The anti-collision strip has a limited coverage area and cannot provide full protection
Weak protection against violent impact
Some car owners have reported that its actual protective effect is limited, and there may be problems such as detachment or affecting the smoothness of car door closure
It is recommended to decide whether to install it based on the vehicle's usage environment. A white body paired with black anti-collision strips may affect the appearance, so it is necessary to confirm the matching effect in advance.
The main malfunction of the rear door anti-collision strip of a car is manifested as damage or detachment of the anti-collision strip, which may cause the car door to be easily scratched and affect its appearance. The following are the specific impacts and countermeasures:
Fault manifestation
Damaged anti-collision strips may cause the car door to be unable to effectively cushion collisions when opening, increasing the risk of the vehicle body being scratched. At the same time, it may disrupt the distance control between the car door and adjacent objects, resulting in the car door not being able to close completely.
Repair suggestions
Youdaoplaceholder0 replace the anti-collision strip
The old anti-collision strips need to be removed and the surface of the car door cleaned to ensure there is no residual glue or dirt.
Select new anti-collision strips that match the color of the original vehicle (such as stainless steel, rubber, etc.) and stick them in the original position.
Youdaoplaceholder0 material selection
The rubber anti-collision strip has good elasticity and can buffer collisions. Stainless steel or engineering plastics of the same color are more durable and aesthetically pleasing.

Avoid using glue for bonding. It is recommended to use 3M tape or AB glue for fixation to ensure a tight fit without air bubbles.
The rear door anti-collision strips of automobiles mainly achieve their protective functions through the following principles:
Anti-collision protection
Anti-collision strips are made of elastic materials (such as rubber or TPU). When the car door opens or closes and comes into contact with adjacent vehicles or obstacles, they absorb the impact force through the elastic deformation of the material, reducing the damage to the car body and other vehicles caused by scratches.
Sound insulation and noise reduction
Some anti-collision strips (such as those made of TPU material), through their material properties, act as a buffer when the car door is closed, reducing the noise generated by the contact between the metal car door and the vehicle body.
Wear-resistant and weathering
High-quality anti-collision strips feature UV resistance and aging resistance, allowing them to adapt to outdoor environments for a long time and prevent material hardening or fading due to sun exposure and rain.
Decorative
Some of the anti-collision strips are in low-key colors such as matte black, which can be integrated into the body line design and serve both protective and aesthetic functions.
