Self-adapting closing type car door

Abstract

The invention relates to a self-adapting closing type car door. The car door comprises a car door body (1), a car door lock, a control module (2), a power source (3), a first pressure sensor (4), an acceleration sensor (5), a rotating motor (6) and a miniature electric control telescopic rod (8), wherein the power source (3), the first pressure sensor (4), the acceleration sensor (5), the rotating motor (6) and the miniature electric control telescopic rod (8) are connected with the control module (2) respectively. Based on the designed technical scheme, the hardware is assembled, so that the self-adapting closing type car door is obtained; the action of door closing is sensed through the sensors; the car door body (1) can be automatically closed through the rotating motor (6) at a moderate speed; in addition, the car door lock is designed to be an electric control lock catch, and the electric control contact type closing mode is introduced; in this way, collision between the car door body (1) and a corresponding car door frame is eradicated thoroughly, mute door closing is achieved, and protection for the car door body (1) is really achieved.

Description

technical field [0001] The invention relates to a self-adaptive closed automobile door, which belongs to the technical field of automobile industry. Background technique [0002] The quality of a car door is mainly reflected in the anti-collision performance of the car door, the sealing performance of the car door, the convenience of opening and closing the door, and of course other indicators of use functions; among them, the anti-collision performance is particularly important, because the side collision of the vehicle At the same time, the buffer distance is very short, and it is easy to hurt the people in the car. Therefore, there will be at least two anti-collision bars in a good car door, and the weight of the anti-collision bar is relatively heavy, that is to say, a good car door is indeed heavier. But it cannot be said that the heavier the door, the better. If the safety performance of the current new cars can be guaranteed, the designers will try to reduce the wei...

Problems solved by technology

[0005] Looking at the automobile doors of the prior art above, it can be seen that the automobile doors of the prior art mainly carry out different improved designs in terms of materials and structures, but in various improved designs for automobile doors, designers and manufacturers have overlooked one The detail problem is that in the actual use of the car door, people often cannot grasp the appropriate force when closing the door. If the force is light, the car door cannot be closed; Collision, if the car door often collides heavily with the corresponding door frame, it may cause damage to the car door. Once the car door is damaged, it will not only face high maintenance costs, but also delay the normal use of the car; not only that, the existing technology The closing operation of the car door in China is realized by the collision between the mechanical lock on the car door and the snap ring on the corresponding door frame, that is, the collision between the mechanical lock and the snap ring can lock the door. As far as impact is concerned, even if the most appropriate force is used to collide, there will still be sound, which will affect the user experience, and the long-term impact operation between the mechanical lock and the snap ring may cause damage to the mechanical lock or snap ring. Reduce the service life of the mechanical lock and snap ring. Similarly, once the mechanical lock or snap ring is damaged, it will not only affect the normal use of the drivers and passengers, but also the maintenance is very troublesome.
