How To Close The Car Door Without Damaging The Vehicle

Drivers have all experienced something like this: when someone gets out of the car, there's a loud "bang" sound, which shakes the ears of those inside the car and makes the driver's heart tremble!

This is because the people outside the car don't feel the loudness of the door closing sound, but the people inside can clearly sense it. And many people may not understand what to do if they don't close the door forcefully, and the door won't close properly?

Closing the door forcefully may cause varying degrees of damage to the car itself and the passengers inside. Why is that? Let's start with the structure of the car door: nowadays, the structure of car doors is becoming increasingly complex, with many circuits and lines inside, including numerous parts: door locks, glass lifters, horns, anti-collision beams, waterproof layers, and sound insulation layers etc.

1. Damage to the car door
The car door is connected to the car body through hinges and limiters. The former is for fixation, and the latter limits the opening angle of the door. Closing the door forcefully will cause impact to the complex motor circuit structure and components inside the door. Over time, this can easily lead to abnormal sounds and be difficult to cure. The first to be harmed are the hinges and limiters. The sound insulation layer will be severely damaged. If the door is closed improperly, the noise will increase sharply. The door frame sealing rubber strips are also severely affected. The sealing strips are rubber products that are exposed to wind and rain all year round and will naturally age. The sealing strips that have been subjected to strong impact will be more likely to deform and crack... The most severely damaged part is the sensor on the door that alerts when the door is not closed properly. To give an inappropriate example, if you hit the keys on the keyboard forcefully every day, the keyboard won't last long and will break. The force required to close the door is much greater than the force you use to hit the keys. You can imagine that the sensor will also be greatly affected.

2. Damage to People
Apart from causing damage to the vehicle itself, it also causes varying degrees of damage to the passengers inside the vehicle. Since the interior is a sealed space, the airflow caused by forcefully closing the door will affect the air pressure inside the enclosed space, causing pain in the eardrums of the driver or passengers. This is also an issue reflecting the basic quality of each passenger.

3. How to Close the Door Correctly
In a nutshell, slamming the door forcefully is not something to be excited about. If it doesn't affect the normal closing process, then how should one close the door correctly?

In fact, whether the door is closed tightly or not is determined by the working conditions of the sound insulation cotton, sealing strips, and anti-collision damping inside the door. As long as you use an appropriate amount of force, it will be sufficient. It is recommended that after getting out of the car, push the door to a position 10-15 centimeters away from the vehicle body, and then close the door slightly with more force. You can also push it slowly until the door is closed and then release your grip.
