Separate middle door transmission mechanism

Abstract

The invention belongs to the field of automobile door lock systems and particularly relates to a separating middle door transmission mechanism. The separating middle door transmission mechanism comprises a bottom plate. The bottom plate is provided with an inner handle shaft; a left inward opening rocker arm is pressed at the inner side of the bottom plate by a separation blade integrally connected with the lower part of the inner handle shaft; the part of the inner handle shaft, passing through the outer side of the bottom plate, is provided with an inward opening torsional spring and a left inward opening linkage arm in sequence; the bottom plate is hinged to a left rear lock opening arm, an opening linkage plate and a left outward opening push plate corresponding to the upper right of the inner handle shaft by a rear lock opening arm riveting shaft. According to the mechanism, an outer handle opening device, an inner handle opening device, a locking and unlocking device and a children safety switch are separately arranged at different positions of the bottom plate, and therefore, the condition that the same shaft is provided with multiple layers of parts is avoided, accumulated tolerance is reduced, and the condition that the middle door transmission mechanism cannot stably and accurately work is avoided.

Description

technical field [0001] The invention belongs to the field of automobile door lock systems, in particular to a separated middle door transmission mechanism. Background technique [0002] The existing automobile sliding door lock and the handle need to be connected through a transmission mechanism, and the transmission mechanism drives the opening of the front lock, rear lock and lower lock. In addition to the above-mentioned opening functions, the locking and unlocking mechanism, children The safety switch and other functions are integrated on the transmission mechanism, and the components involved in the transmission part are all riveted on the bottom plate through the same shaft, so it is necessary to rivet multi-layer parts or gaskets on the shaft (generally less than 5 layers, more than 7 layers) , 8 layers), due to the manufacturing tolerances of the bottom plate and transmission parts, the cumulative tolerance is very large. When the shaft steps are produced with the up...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a simple, ingenious and reasonable separated middle door transmission mechanism. The child safety switch is arranged separately on different positions on the bottom plate, so as to avoid the situation of installing multi-layer parts on the same axis, reduce the cumulative tolerance, and thus solve the situation that the middle door transmission mechanism cannot work stably and accurately
