Description

Door fixing mechanism

The present invention relates to a door fixing mechanism, and more particularly to a door fixing mechanism for improving the rigidity of a vehicle and optimizing its handling and stability.

In order to increase the maneuverability (Improved Maneuverability), existing vehicles mainly rely on the setting of the chassis suspension system. Since the vehicle body structure is a single structure, the suspension system of the vehicle is mounted on the structure of the vehicle body. When the suspension system acts, the stress to be applied will relatively cause the load on the vehicle body. Therefore, the rigidity of the vehicle body supporting the suspension system is preferably as good as possible, so that the smaller the distortion amount, the better. When the suspension system is more and more, the more rigid car body structure is needed, so that the suspension system can work perfectly and fully, and the driving dynamics of the car body is more complete.

In addition, the vehicle research report further pointed out that when the vehicle is cornering, changing lanes, or even driving a mountain road, the door will generate inertial force and increase the steering wheel rotation amplitude, thereby affecting the handling and stability of the vehicle. Although the door hook forms a locked state with the lock hook of the vehicle body, so that the door becomes a part of the vehicle body, substantially there is still a gap after the door and the vehicle body are locked. Therefore, when the vehicle is in a driving state such as turning, the door may be displaced and cannot completely close with the vehicle body, thereby causing an increase in the deflection of the steering wheel, thereby reducing the handling of the vehicle.
