Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to a door stopper structure. Background Art

[0002] The door limiter is a limiting structure for the opening and closing of the door. During the closing process of the rail transit plug door, there is often a large collision force between the two doors and the door is not tightly closed. The existing method of closing the rail transit plug door to prevent excessive collision is mostly to weaken the collision force by installing rubber strips at the joints of the two doors. This operation method can reduce the impact and noise of the collision on the door to a certain extent, but it is only a temporary solution. When excessive collision occurs occasionally, it is still easy to affect the door body or the driven electrical equipment, affecting the driving service life of the door.

[0003] In the prior art, a patent application with application number (CN202320471136.5) discloses a door limiter structure including a door, a pulling synchronous shaft, a sliding assembly and a deceleration limit assembly.

The sliding assembly is movably arranged on the side of the vehicle door close to the support swing arm. The movable assembly includes a limit slide. A limit slide with an elastically supported deceleration block is provided on the supporting door rail groove structure of the door. When the door is normally opened and closed, an auxiliary limit assembly is provided in the door rail groove to slow down and limit the movement of the door, thereby reducing the impact speed between the two doors and the termination activity at a predetermined position. The structure of mechanical limit and friction has higher stability in use, simple and convenient operation, accurate and reliable positioning, and avoids the influence of excessive collision on the driving equipment.

[0004] In the prior art, a pulling synchronization shaft and a deceleration limit assembly are added, which will actively and effectively solve the problem that when excessive collision occurs, it is easy to affect the door body or the driven electrical equipment and affect the driving service life of the door. However, its limiting connection method adopts the traditional snap-on limiting structure, so in special circumstances such as excessive vibration, effective connection cannot be made, thus posing a huge safety hazard.
