Sliding door transmission device for automobile

Abstract

The invention relates to a sliding door transmission device for an automobile, and the sliding door transmission device comprises a middle hinge, an inhaul cable, a slide rail and a motor transmission part, wherein the inhaul cable comprises a front inhaul cable and a rear inhaul cable which are connected with the two sides of the middle hinge, the output terminal of the motor transmission part is connected with the inhaul cable, the head of the inhaul cable is provided with a connecting head, and the part, close to the connecting head, of the inhaul cable is provided with a connecting part, the connecting head is connected onto the middle hinge. The sliding door transmission device for the automobile is characterized in that the connecting head is movably connected with the middle hinge by virtue of a rotating mechanism, the middle hinge is arranged at the part of the slide rail which is in a turning state, and the connecting head rotates relative to the middle hinge and maintains to be in the same radian with the slide rail, so as to turn off naturally. Compared with the prior art, the sliding door transmission device for the automobile has the advantages that when the middle hinge turns off at the part of the slide rail which is in the turning state, as the rotating mechanism exists, the connecting head rotates relative to the middle hinge and maintains to be in the same radian with the slide rail, so as to turn off naturally, thus the connecting part does not bend, and long-term stable operation is guaranteed.

Description

[0001] This application is a divisional application based on the Chinese invention patent application with the application number 201010529835.8, the filing date of October 29, 2010, and the invention title of "Automobile Sliding Door Transmission". Technical field [0002] The invention relates to an automobile sliding door transmission device, in particular to a connection structure of an automobile sliding door and a cable. Background technique [0003] The existing automobile electric sliding door transmission device, such as figure 1 As shown, it generally includes a middle hinge 1a, a front cable 2a, a rear cable 3a, a guide seat 7a, a slide 4a, a guide wheel 71a, and a motor transmission part 5a. The front cable 2a and the rear cable 3a pass through their respective cables The head 6a is connected to both sides of the middle hinge 1a. The guide seat 7a is provided with a guide wheel 71a for guiding the cable. The motor transmission part 5a is installed between the side walls...

Problems solved by technology

like figure 2 As shown, the connection between the cable head 6a and the middle hinge 1a adopts the die-casting "T" head to connect with the opening groove of the mounting plate 11a on the middle hinge. This structure is simple in design and has been used for many years, but the middle hinge 1a runs to When the middle slideway 4a turns, because the cable head 6a is fixedly connected with the middle hinge 1a, it will not turn together with the middle hinge 1a, so that the cable is bent at the cable head joint 61a itself, as image 3 , long-term use, the cable at the connection 61a is easily broken due to its own bending fatigue, which affects normal use
