People who drive more or less have had this experience: someone closes the door with a "bang" when getting off the car, which makes the people in the car tinnitus , which makes the owner tremble!
Because, people outside the car can't feel the sound of the car door, but people inside the car can obviously feel the sound of the car. And many people may not understand, if they don’t work hard, what should they do if the door cannot be closed?
vigorously closing the car door may cause varying degrees of damage to the car itself and the passengers in the car. Why do you say so? Let’s start with the structure of the car door: the structure of the car door is becoming more and more complex, with many circuits and circuits in it, including many parts: door locks, glass lifter , horns and anti-collision beams, waterproof layers and sound insulation layers, etc.
1 and damage to the door
0 The door and body are connected together by hinges and limiters. The former is a fixed function, while the latter limits the opening angle of the door. Close the door vigorously will cause impact on the complex motor circuit mechanisms and components in the door. In the long run, abnormal noises are likely to occur and are difficult to cure. The first things that are hurt are the hinges and limiters. The sound insulation layer will be very damaged, and if the car door is broken, the noise will be stormy. The door frame sealing strip is also affected by strong impact. The sealing strip is a rubber product that is blown away all year round. The sealing strip that will aging in the air and squeeze it with strong force will be more likely to deform and crack... The most easily injured is the sensor on the door responsible for the alarm that the door is not closed. To give an inappropriate example, if you smash the keys on the keyboard every day, the keyboard will break if it is used a few times. The power of closing the door is much greater than the power of you typing the keyboard. It can be imagined that the sensor will also have a great impact.
2 and damage to people
In addition to causing damage to the car itself, it will also cause varying degrees of damage to the passengers in the car. Since the car is a sealed space, the airflow caused by vigorously closing the door will affect the air pressure in the car in the confined space, causing pain in the eardrum of the driver or passenger. Of course, this also reflects the basic quality of each of our passengers.
3, How to correctly close the car door
After all, it is a saying that vigorously slamming the car door is not a joyful thing. Without affecting the normal closing state, how to correctly close the door?
In fact, whether the door is closed tightly is determined by the working status of soundproof cotton , sealing strips and anti-collision damping in the door. As long as you use appropriate strength, it is enough. It is recommended that you push the door 10-15 cm away from the body after getting off the car, and then close the door slightly hard. You can also push it slowly until the door is closed and then let go.
