Vehicle and door limiter and door collision prevention device thereof

Abstract

The invention discloses a vehicle door limiter. The vehicle door limiter comprises an elastic body, wherein a through hole is formed in the elastic body; a damping adjuster shell is arranged at one side of the through hole; a magnet is arranged in one side, far from the elastic body, of the damping adjuster shell, and is connected with a damping adjusting rod coaxially arranged with the through hole; an excitation coil is arranged in one side, near the elastic body, of the damping adjuster shell; and the damping adjusting rod is arranged to be inserted in the excitation coil. The invention further provides a vehicle door collision prevention device and a vehicle. Through the technical scheme, the damping force of the vehicle door limiter to a vehicle door can be adjusted, and when the vehicle door is close to an obstacle within a certain distance, the damping force of the vehicle door can be increased to stop the vehicle door from further approaching the obstacle or even crashing against the obstacle so as to achieve the vehicle door protective effect.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a vehicle door limiter, a vehicle door anti-collision device and an automobile. Background technique [0002] Due to the increasing number of cars in the city, not only the traffic pressure is gradually increasing, but also the parking space is becoming more and more tense. In order to be able to park more vehicles in a limited space, the distance between vehicles must become smaller and smaller when parking, especially the lateral distance between cars. [0003] Therefore, in the process of people getting on and off the car, the car door is easy to bump into vehicles or other obstacles next to it, especially children or the elderly. This will not only easily damage other people's vehicles, but also easily damage your own vehicles. [0004] At present, it is usually used to paste rubber or foam on the door to prevent collisions, but this defense can only play a protective r...
