Stepless vehicle door limit device with emergency locking function

Abstract

The invention relates to a stepless vehicle door limit device with an emergency locking function. The stepless vehicle door limit device comprises a limit assembly and an emergency locking assembly, wherein the limit assembly comprises a rack (4) and a limiter main shaft (7); the rack (4) is movably connected with a vehicle door; one end of the rack (4) is rotationally connected with the vehicle door; a rotary shaft of the rack (4) is parallel to the won rotary shaft of the vehicle door; the limiter main shaft (7) is in threaded connection with a limit block (11) fixed on the vehicle door; a gear (10) coaxially connected with the limiter main shaft (7) and engaged with the rack (4) is arranged at the first end of the limiter main shaft (7); a resistance mechanism is arranged between the second end of the limiter main shaft (7) and the limit block (11); and the emergency locking assembly comprises a sensor, a controller and a locking mechanism. Compared with the prior art, the stepless vehicle door limit device disclosed by the invention is capable of realizing an adjustable stepless limit function, inducing obstacles outside the vehicle door, and locking the vehicle door in case of a danger, thus effectively preventing accident occurrence.

Description

technical field [0001] The invention relates to a vehicle door limiter, in particular to a stepless vehicle door limiter with an emergency locking function. Background technique [0002] The car door stopper is used to limit the opening angle of the car door and provide a certain resistance distance when the door is turned to prevent the door from swinging when the car is parked on a slope or encounters strong winds. [0003] Chinese patent CN201436352U discloses a pull-rod type automobile limiter, including a bracket fixed on the vehicle body, an opening limit mechanism connected to the bracket, and the opening limit mechanism also extends into the opening on the door , the automobile door limiter also includes a housing, the housing is embedded and holds the stopper, the stopper slides along the stop surface of the opening limit mechanism, and the housing also includes a pair of elastic members, the elastic members pair The stop component exerts elastic force to press the...

[0004] But the above-mentioned car door limiter generally can only provide two to three limit points, and the car door can still rotate freely at the non-gear position. With the rapid rise of my country's automobile production and sales, the distance between cars and cars will decrease It will become smaller and smaller, and similar traditional door stoppers are prone to scratches between the doors when the door is opened because the angle of the first gear limit point is set too large, and the limited limit point will also As a result, when the car owner opens and clo
