Do you know the design of the car FR DOOR?

Brilliance FR DOOR is to provide drivers and passengers with access to the vehicle and to isolate outside interference, to a certain extent reduce side impacts and protect passengers. The beauty of a car is also related to the shape of the door. The quality of the door is mainly reflected in the collision resistance of the door, the sealing performance of the door, the convenience of opening and closing the door, and of course, other indicators of the use function. Anti-collision performance is particularly important because when the vehicle has a side collision, the cushioning distance is short, and it is easy to hurt people in the vehicle.

Brilliance FR DOOR

There are at least two collision beams in a good door, and the weight of the collision beam is heavier, that is, the good door is indeed heavier. But it cannot be said that the heavier the door, the better. Now that the new type of car can guarantee safety performance, designers will find ways to reduce the weight of the vehicle including the door (such as using new materials) to reduce power consumption. According to the number of doors, cars can be divided into two-, three-, four-, five-door cars. Most of the cars used for business purposes are four-doors. There are four-door, three-door and five-door (back-door lift-up) cars for domestic use, and two-door sports cars. Zh

4. The door mechanism is operated in reverse, including closing the door freely, and the glass is easy to lift and lower;

5. Good sealing performance requirements;

6. with a large light-transmitting surface, to meet the requirements of lateral vision;

7. It must have sufficient strength and rigidity to ensure the reliable operation of the door, reduce the door vibration, improve the safety of the vehicle's side collision, and prevent the door from sinking;

8. Good door manufacturing and assembly technology.

The door can be divided into the following types according to its opening method:

Sliding door: Even when the car is moving, it can still be closed by the pressure of airflow, which is safer and easier for the driver to observe backward when reversing, so it is widely used.

Reverse door: If the car is not closed tightly when driving, it may be flushed by the oncoming airflow, so it is less used. Generally, it is only used to improve the convenience of getting on and off the car and to meet the needs of the etiquette.

Horizontally moving door: Its advantage is that it can be fully opened even when the distance between the body wall and the obstacle is small.

Lift-up doors: Widely used as back doors for passenger cars and light passenger cars, but also for low-profile cars.

Folding doors: They are widely used in large and medium-sized passenger cars.
