The working principle of the front door anti-collision strip
The working principle of the front door anti-collision strip is to absorb the impact force when the door is opened through its elastic material, reducing the direct collision between the door and adjacent vehicles or obstacles, thereby protecting the safety of the vehicle body and pedestrians.
Material properties
It is usually made of elastic materials such as rubber, TPU (thermoplastic polyurethane elastomer) or EVA (ethylene-vinyl acetate copolymer), which have high elasticity, impact resistance and wear resistance, and can effectively buffer energy during collision.
Installation method
Most products adopt magnetic attraction, adhesive or telescopic designs, without the need for glue fixation, and are easy to install. For instance, the magnetic design can be directly attached to the edge of the car door, while the adhesive type is temporarily fixed by adhesive.
Protective effect
Absorb collision energy through material deformation, reduce the impact force when the car door opens, and avoid scratches. Some products also have sound insulation functions to reduce the noise when opening the door.
The front door anti-collision strip is a protective device installed on the front door of a car. It is mainly used to prevent scratches from surrounding objects when opening the door and protect the car paint from damage.
Main functions
Youdaoplaceholder0 Anti-scratch : By covering the edge of the car door, it prevents the paint surface from being damaged due to friction with adjacent vehicles or obstacles when opening the door. It is especially suitable for scenarios with narrow parking Spaces.
Youdaoplaceholder0 Sound insulation and noise reduction : Some models use special materials to reduce the metal collision sound when opening the door, enhancing the comfort of use.
Youdaoplaceholder0 Invisible beauty : Featuring a black matte design, it conforms to the door lines without affecting the overall aesthetic appearance of the vehicle body.
Material characteristics
Youdaoplaceholder0 TPU material : soft and wear-resistant, suitable for daily use, with anti-collision and cushioning properties.
Youdaoplaceholder0 Magnetic attraction design : Some products do not require drilling for fixation and can be directly attached to the surface of the car door, facilitating temporary installation.
It is recommended to choose the appropriate anti-collision strips based on the material of the car door, and give priority to environmentally friendly materials to avoid chemical residues.
The main function of the front door anti-collision strip is to protect the car door from scratches and impacts , while reducing the degree of damage. The following are the specific functions and precautions:
Protect the car door structure
Anti-collision strips can prevent car doors from deforming or cracking in minor collisions by absorbing and dispersing impact forces, thereby reducing maintenance costs.
Extend the service life
Frequent opening and closing of car doors may cause edge wear. Anti-collision strips can reduce scratches caused by direct contact of metal parts and indirectly extend the service life of car doors.
Material and installation characteristics
Youdaoplaceholder0 Material : mostly TPU or silicone material, soft and wear-resistant, can buffer external force impact
Youdaoplaceholder0 Installation : Usually, 3M adhesive is used for fixation. It is necessary to ensure that the bonding position is accurate (such as the raised part in the middle of the car door) to avoid the adhesive strip shifting and affecting the effect
Precautions
Some car owners have reported that the anti-collision strips offer limited protection against severe impacts and may affect the sealing performance when the car doors are closed. If the vehicle is originally equipped with anti-collision designs (such as side skirt protection strips in some models), original factory parts can be given priority.
The malfunction of the front door anti-collision strip can be dealt with by repair or replacement. If the anti-collision strips are deformed or damaged, the following solutions can be referred to:
Repair method
Youdaoplaceholder0 Slight deformation : If the anti-collision strip shows local depressions due to collision, you can try to correct it or reinforce it with 3M double-sided tape (make sure the adhesive is in good condition).
Youdaoplaceholder0 Severe damage : If deformed or damaged and cannot be repaired, it is recommended to replace the anti-collision strip with a new one. Some models require the removal of door trim panels. It is recommended that professionals handle this.
Installation Precautions
The anti-collision strips should be tightly attached to the edge of the car door to avoid affecting the flexibility of the car door's opening and closing.
Give priority to U-shaped anti-collision strips with double-sided tape, as they offer a larger protection area and are easier to install.
If it is difficult to repair it by yourself, it is recommended to contact the 4S store or professional maintenance personnel for handling to avoid further damage to the door structure.
