Vehicle door linkage mechanism

Abstract

The invention discloses a vehicle door linkage mechanism. The vehicle door linkage mechanism comprises a locking lever, a fixing shaft, a driving sliding cylinder, a driven sliding cylinder, a linkage piece, a driving shaft, a driven shaft, a first long guide column and a second long guide column, wherein the first long guide column and the second long guide column are fixed in parallel, and the driving sliding cylinder and the driven sliding cylinder sleeve the first long guide column and the second long guide column respectively to slide and are connected through the linkage piece to realize synchronous movement. The fixing shaft is fixed between the first long guide column and the second long guide column, the driving shaft and the driven shaft are mounted on the driving sliding cylinder and the driven sliding cylinder respectively, the locking lever is mounted on the fixing shaft and rotates around the axis of the fixing shaft, and when the driving sliding cylinder and the driven sliding cylinder slide to the locking position, the driving shaft and the driven shaft make contact with one end of the locking lever. According to the lever principle, the driving sliding cylinder of the linkage mechanism locks the driven sliding cylinder, it is avoided that the linkage piece is subjected to alternating force for a long time, and when the linkage piece is broken, it can be guaranteed that a vehicle door is in a locked state.

Description

technical field [0001] The invention relates to a linkage mechanism, in particular to a vehicle door linkage mechanism. Background technique [0002] In the field of passenger vehicle doors, the mechanism is the core component of the door, which is used to drive the door leaf to move according to the predetermined trajectory. The linkage mechanism connects the main and driven door leaves through linkages (including belts, wire ropes and chains, etc.) to realize the relative movement of the left and right door leaves, which can shorten the length of the mechanism and simplify the transmission structure, thereby reducing the installation space of the mechanism and reducing the manufacturing cost. However, during the operation of the vehicle, when the linkage is elastically deformed under force, the door will not be closed tightly, the vibration and noise will be large, and the ride comfort will be affected. However, if the linkage parts bear the alternating force for a long t...

AI Technical Summary

Problems solved by technology

However, during the operation of the vehicle, when the linkage is stressed and deforms elastically, the door will not be closed tightly, and the vibration and noise will be large, which will affect the ride comfort.

However, the linkage parts bear the alternating force for a long time, which will cause fatigue fracture, affect the driving safety and increase the after-sales cost
