The beauty of the car is also related to the shape of the door. The quality of the door is mainly reflected in the anti-collision performance of the door, the sealing performance of the door, the convenience of opening and closing the door, and of course, other indicators of use functions. The anti-collision performance is particularly important because when the vehicle has a side impact, the buffer distance is very short and it is easy to hurt the personnel in the vehicle. There will be at least two anti-collision beams in a good door, and the weight of the anti-collision beam is heavier, that is to say, a good door does put more emphasis on it. But it cannot be said that the heavier the door, the better. If the safety performance of current new cars can be guaranteed, designers will try their best to reduce the weight of vehicles, including doors (such as using new materials) to reduce power consumption. According to the number of doors, cars can be divided into two door, three door, four door and five door cars. Most cars used for official purposes are four doors, cars used for family purposes have four doors, three doors and five doors (the back door is lift type), while sports cars are mostly two doors. classification Doors can be divided into the following types according to their opening methods: Open door: even when the car is driving, it can still be closed by the pressure of air flow, which is relatively safe and convenient for the driver to observe backward when reversing, so it is widely used. Reverse opening door: when the car is driving, if it is not tightly closed, it may be washed away by the oncoming airflow, so it is less used. It is generally only used to improve the convenience of getting on and off and meet the needs of welcome etiquette. Car door Car door Horizontal mobile door: its advantage is that it can still be fully opened when the distance between the side wall of the vehicle body and the obstacle is small. Lift up door: it is widely used as the back door of cars and light buses, as well as low cars. Folding door: it is widely used in large and medium-sized buses. Integral door: the inner and outer plates are formed by stamping the whole steel plate and wrapping the edges. The initial mold investment cost of this production method is large, but the relevant inspection fixtures can be reduced accordingly, and the material utilization rate is low. Split door: it is welded by the door frame assembly and the door inner and outer panel assembly. The door frame assembly can be produced by rolling, with low cost, high productivity and low overall corresponding mold cost, but the cost of later inspection fixture is high and the process reliability is poor. The overall cost difference between integral door and split door is not very large. The relevant structural form is mainly determined according to the relevant modeling requirements. Due to the high requirements of automobile modeling and production efficiency, the overall structure of the door tends to be split.
