Automobile door limiting device

Abstract

The invention discloses an automobile door limiting device which comprises a shell, a limiting rod, limiting locks and speed reduction assemblies. The shell is connected with an automobile door through a bolt. The limiting rod penetrates in the shell, one end of the limiting rod is connected with an automobile door pillar, limiting grooves are symmetrically formed in the upper side face and the lower side face of the limiting rod in a concave manner, and speed reduction grooves are symmetrically inwards formed in the left side face and the right side face of the limiting rod in a concave manner. The limiting locks are symmetrically arranged at the positions, on the upper side and the lower side of the limiting rod, in the shell and are matched and connected with the limiting grooves in theupper side face and the lower side face of the limiting rod to limit the limiting rod. The speed reduction assemblies are symmetrically arranged at the positions, on the left side and the right sideof the limiting rod, in the shell and are matched and connected with the speed reduction grooves formed in the left side face and the right side face of the limiting rod to limit the limiting rod. Theproblem that after an automobile driver conducts parking on the roadside, a person in an automobile suddenly opens the door, and if pedestrians or automobiles pass through the opening side in the close range at the moment, colliding is likely to happen is solved.

Description

technical field [0001] The invention relates to the technical field of vehicle engineering, in particular to an automobile door limiting device. Background technique [0002] At present, on the roads of cities and towns in our country, the phenomenon of motor vehicles, bicycles and pedestrians running side by side is relatively serious. When the motor vehicle driver parks on the side of the road, the occupants of the car suddenly open the door unconsciously or without fully observing the road conditions behind the car. If a pedestrian or vehicle passes by the side of the door at close range at this time, it is easy to send a collision, directly or indirectly result in personal injury or death. Contents of the invention [0003] The purpose of the present invention is to provide a car door limit device, which utilizes a deceleration groove and a limit groove to limit and delay the door limit device to solve the problem of people in the car suddenly opening the door after t...
