The door handle is generally disposed on a side of the door away from the rotating shaft for controlling the opening and closing of the door lock. In the prior art, an automatic locking device is generally arranged in a vehicle door, and when the vehicle runs, the vehicle door can be locked by the automatic locking device and cannot be opened by people in the vehicle. The automatic locking device can also firmly lock the vehicle door when side impact occurs, so that passengers are prevented from directly suffering from external impact, and danger is reduced. Therefore, the safety of the vehicle is directly influenced by the structure and the performance of the automobile door. And, what is the first time it is the performance of the crash, particularly the performance of a side crash.

The inventor finds out in research that the problem of opening of the vehicle door occurs when a collision accident happens on many vehicle types. At present, the conventional method is to add a reinforcing plate penetrating through the front and the rear of a door window frame to enhance the collision performance, but the conventional method is only to enhance the collision performance at a windowsill, so that the intrusion amount of a side impact door can be properly reduced, but a door sheet metal around a door handle does not have a reinforcing structure, and when the side impact occurs, the deformation of the door outer plate sheet metal drives a door handle pull rod to move, so that the door is opened, and the risk is brought to the safety of passengers.

Therefore, the inventors have studied and designed a door reinforcing structure provided between a door outer panel and a door inner panel, the door reinforcing structure including: an installation part and a buffer part. The mounting part is fixedly connected with the outer plate of the vehicle door; the buffer part is connected with the installation part, protrudes towards the direction of the inner door plate along the plane where the installation part is located, and forms a protection cavity together with the outer door plate and the inner door plate in an enclosing mode, and the buffer part is provided with an installation hole corresponding to the position of the door handle.

In the vehicle door reinforcing structure, the vehicle door and the vehicle, the mounting part is arranged to connect and fix the vehicle door reinforcing structure and the vehicle door outer plate, so that the position stability of the vehicle door reinforcing structure is ensured, and the condition that the vehicle door reinforcing structure moves to cause the failure of an anti-collision function when a side collision occurs is prevented; the buffer part is arranged to form a buffer cavity between the outer door plate and the inner door plate, so that the impact force generated during side impact of the door is absorbed, and the safety of passengers is improved. In addition, the installation hole arranged at the position corresponding to the door handle in the buffer part can form an avoidance space for the door handle, can avoid the damage of the automatic locking function of the door caused by the structural deformation of the door handle when the side impact occurs, prevent the automatic opening of the door, protect the safety of passengers and improve the side impact safety of the vehicle body.

The vehicle door reinforcing structure and the vehicle door in the embodiment of the application can be applied to various side-opening mobile devices with the vehicle door handle, and can effectively prevent the damage of passengers caused by the fact that the vehicle door handle is automatically opened when the vehicle door handle is subjected to side collision.
