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
The application is the divisional application of the Chinese invention patent application based on application number is 201010529835.8, the applying date is on October 29th, 2010, denomination of invention is " transmission device for sliding door of automobile ".
Technical field
The present invention relates to a kind of transmission device for sliding door of automobile, relate in particular to the connection structure of a kind of automobile sliding door and drag-line.
Background technology
Slide driving device in existing motorcar electric, as shown in Figure 1, generally comprise middle hinge 1a, fore stay 2a, back stay 3a, guide holder 7a, slideway 4a, track adjusting wheel 71a, motor transmission part 5a, fore stay 2a and back stay 3a are connected in middle hinge 1a both sides by Cable head 6a separately, guide holder 7a the inside is provided with the track adjusting wheel 71a for the drag-line that leads, motor transmission part 5a is contained between the car gusset of automobile, motor transmission part 5a drives drag-line to move forward and backward, thereby realizes slide auto-switch function.As shown in Figure 2, the mode that Cable head 6a is connected with middle hinge 1a adopts die casting T-shape head to be connected with the adapter plate 11a open slot on middle hinge, this structure design is simple, and apply for many years, but when central hinge 1a runs to middle slideway 4a corner, because Cable head 6a is fixedly connected with middle hinge 1a, can be along with middle hinge 1a turns together, thereby make drag-line produce bending at Cable head junction 61a itself, as Fig. 3, long-term use, drag-line is easy to because of self bending fracture by fatigue at junction 61a, uses thereby impact is normal.
Summary of the invention
Technical matters to be solved by this invention is while providing a kind of connector to turn round with middle hinge for the above-mentioned state of the art, not make connecting portion produce the transmission device for sliding door of automobile of bending.
The present invention solves the problems of the technologies described above adopted technical scheme: a kind of transmission device for sliding door of automobile, comprise middle hinge, drag-line, slideway and motor transmission part, aforesaid drag-line comprises the fore stay and the back stay that are connected in middle hinge both sides, aforesaid motor transmission part clutch end is connected with drag-line, the head of aforementioned drag-line is provided with connector, drag-line has connecting portion near connector, this connector is connected on middle hinge, it is characterized in that described connector is flexibly connected by a rotating mechanism with middle hinge, and, described middle hinge is positioned under the state of slideway corner, the relatively middle hinge through of described connector also keeps the radian the same with slideway and takes advantage of a situation and turn round,
Described connector has through hole, and described rotating mechanism comprises
Adapter plate, is located on described middle hinge;
Cylinder, one end is fixed on aforementioned adapter plate, and the other end is arranged in the through hole of described connector and exposes exposed end, and aforementioned connector rotates relative to cylinder physical efficiency; And
Baffle plate, is located on described middle hinge and has the mounting hole wearing for aforementioned cylinder exposed end.
Further, described baffle plate cross section is " Z " shape at right angles, comprise the first horizontal part and the first kink, and described mounting hole is opened on this first horizontal part, aforesaid the first kink is limited in the avris of middle hinge, described adapter plate cross section is right angle " Z " shape of handstand, comprise the second horizontal part and the second kink, and described cylinder is longitudinally located on this second horizontal part, aforesaid the second kink is close to the first kink and is jointly fixed on middle hinge avris with a transom, and, gap between aforesaid the first horizontal part and the second horizontal part is greater than connector axial distance.
Compared with prior art, the invention has the advantages that: middle hinge is positioned under the state of slideway corner, because rotating mechanism exists, the relatively middle hinge through of connector also keeps the radian the same with slideway and takes advantage of a situation and turn round, thereby connecting portion does not produce bending, guarantee permanent smooth operation; Integral structure is simple, easy for installation, respond well.
