Abstract

The invention discloses a sliding door limiting device, and relates to the field of automobile sliding door structures. The sliding door limiting device comprises a triggering opening and closing device, a limiting device body and a hydraulic transmission device for realizing linkage of the triggering opening and closing device and the limiting device body; the triggering opening and closing device comprises a pressing telescopic device arranged at the tail end of a sliding door lower hinge sliding rail and a first piston arranged at the telescopic end of the pressing telescopic device; the hydraulic transmission device comprises a hydraulic pipe and hydraulic oil arranged inside the hydraulic pipe; the limiting device body comprises an automatic resetting telescopic limiting device fixedto the sliding door extreme opening position and a second piston moving synchronously with the telescopic part of the automatic resetting telescopic limiting device; the first piston and the second piston are arranged at two ends of the hydraulic pipe respectively; and the hydraulic oil is located in closed area formed by the first piston, the second piston and the hydraulic pipe. By the aid of the sliding door limiting device, the problems that existing sliding door limiting devices are strenuous, sliding doors are blocked to open and close, structures are complex and opening and closing staywires are required to be arranged are solved.

Description

technical field [0001] The invention relates to the field of automobile sliding door structures, in particular to a sliding door limiting device. Background technique [0002] In the existing sliding door system of MPV models, generally a reed type mechanical limit mechanism or a limit lock device is used to realize the limit of the sliding door when the maximum position is opened, but the reed type limit mechanism has the problem that the sliding door is stuck and the force is large. And other issues. The structure of the limit lock device is complicated, and switch pull wires need to be arranged, and it is not beautiful. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a sliding door limiting device. The present invention solves the problems that the current sliding door limiting device is laborious, the sliding door is stuck on and off, the structure is complicated, and the switch pull wire needs to be arrange...
