The drive unit of vehicle slide-door
Technical field
The utility model relates to the drive unit of vehicle slide-door.
Background technology
At present in the drive unit of vehicle slide-door, the CD-ROM drive motor mechanism of slide is installed on the slide, CD-ROM drive motor mechanism is mainly by CD-ROM drive motor, driving-disc, the silk wheel is formed, two wire drawings of CD-ROM drive motor mechanism output, change from the traffic direction of the wire drawing of motor output by one group of pulley gear and to make the direction of wire drawing operation consistent with the direction of motion of slide, again through behind one group of pulley mechanism on the hinge in being fixed on two discount partial fixings of wire drawing on the secondary rail of middle guide, the secondary rail of middle guide is the level of state and is fixed in vehicle body, drive time pulley mechanism by pulley mechanism on the hinge in being fixed on and the relative motion between wire drawing, thereby hinge is along with it moves in driving, and realizes the motorized motions of slide.When slide cut out, the secondary rail of middle guide was adjacent with slide, and when opening slide, slide slides to the secondary rail direction of middle guide.Such structure is installed on the slide owing to the main body driving mechanism, thereby has caused the weight of slide to strengthen, and has promptly increased sliding door electric and has driven desired power.And under the constant situation of the power upper limit that motor can provide, stand-by power will be reduced.The CD-ROM drive motor outlet direction and the slide direction of motion have an angle, thereby have increased the pulling direction that a large amount of parts changes wire drawing, and the length of wire drawing and pillar thereof is longer, and CD-ROM drive motor need occupy the installing space of slide inside simultaneously.
The utility model content
Technical problem to be solved in the utility model is: provide a kind of simple in structure, reduce the slide resistance of motion, reduce cost, saved the drive unit of the vehicle slide-door in slide internal placement space simultaneously.
Solve this technical problem, the technical solution of the utility model is: a kind of drive unit of vehicle slide-door, the wire drawing fixture block mechanism of fixedlying connected that comprises two wire drawings that CD-ROM drive motor mechanism, CD-ROM drive motor mechanism draw, the attached rail of middle guide, attached rail one end of middle guide with slide, described CD-ROM drive motor mechanism is positioned at the other end of the attached rail of middle guide, the attached rail of wire drawing fixture block mechanism and middle guide is slidingly connected, and two wire drawings that CD-ROM drive motor mechanism draws connect into closed-loop with wire drawing fixture block mechanism respectively.
Described wire drawing fixture block mechanism is mainly by forming with the middle hinge that is connected with sliding door with the fixture block that the attached rail of middle guide is slidingly connected, and fixture block and middle hinge are connected to an integral body.
The two ends of the secondary trailer structure of described middle guide are respectively arranged with the wire drawing guide wheel that the wire drawing of fixedlying connected with the secondary rail of middle guide is walked around.
Described two wire drawings are outside equipped with the wire drawing pillar.
The drive unit of the utility model vehicle slide-door adopts such structure, compared with prior art, the attached rail of middle guide still is the level of state and is fixed in the same position of vehicle body, when slide cuts out, the attached rail of middle guide is adjacent with slide, the attached rail of middle guide is connected with slide by middle hinge, and when slide was opened, slide slided to the attached rail direction of middle guide.CD-ROM drive motor is positioned at the position of the other end of the attached rail of middle guide near the D post, the top and the bottom that two wire drawings that CD-ROM drive motor is drawn are positioned at the attached rail of middle guide form closed-loop, when CD-ROM drive motor is worked, CD-ROM drive motor drives the rotation of silk wheel by driving-disc, in wire drawing pulling fixture block on the guide wheel to the right or to left movement, guide wheel and wheel frame guarantee its running orbit, realize the opening and closing of slide.The outlet direction of CD-ROM drive motor and the plane of movement of middle hinge are unanimous on the whole, do not need painstakingly to adjust the direction of wire drawing.Therefore, simple in structure, reduce the slide resistance of motion, reduce cost, saved the inner arrangement space that CD-ROM drive motor is installed of slide simultaneously.

In Fig. 1,1, the attached rail of middle guide; 2, fixture block; 3, middle hinge; 4, preceding wire drawing guide wheel; 5, back wire drawing guide wheel; 6, waterproof is emitted; 7, CD-ROM drive motor mechanism; 8, wire drawing and wire drawing pillar; 9, wire clamp.
The specific embodiment
As shown in Figure 1, vehicle slide-door mainly is made up of wire drawing guide wheel, wire drawing and the wire drawing pillar 8 at CD-ROM drive motor mechanism 7, the attached rail 1 of middle guide, wire drawing fixture block mechanism, the attached rail of middle guide 1 two ends.CD-ROM drive motor mechanism mainly is made up of CD-ROM drive motor, driving-disc, silk wheel; The attached rail of the attached rail 1 of middle guide is fixed on the middle guide, and middle guide and attached rail all are made up of the curved arc section that extend straight rail section and its end; Wire drawing fixture block mechanism mainly is made up of with the middle hinge 3 that is connected with slide fixture block 2, and fixture block 2 is connected to an integral body with middle hinge 3, and fixture block 2 can move back and forth along the attached rail 1 of middle guide; The wire drawing guide wheel at the attached rail of middle guide 1 two ends is preceding wire drawing guide wheel 4 and back wire drawing guide wheel 5, and preceding wire drawing guide wheel 4 is fixed in the end points of the attached rail 1 curved arc section of middle guide, and back wire drawing guide wheel 5 is fixed in the straight rail section end points of the attached rail 1 of middle guide; Wire drawing is positioned at the wire drawing pillar, from two wire drawings of CD-ROM drive motor mechanism 7 output, wherein one from the attached rail of middle guide 1 inboard by the wire drawing pillar through three wire clamps 9, walk around preceding wire drawing guide wheel then, discount by the wire drawing head is stuck on the fixture block 2 again, and the realization wire drawing is connected with middle hinge 3; Another root is from the attached rail of middle guide 1 outside, and by walking around wire drawing guide wheel in back behind the wire drawing pillar, the discount by the wire drawing head is stuck on the fixture block 2 again, and the realization wire drawing is connected with middle hinge 3.Described CD-ROM drive motor mechanism and the attached rail of middle guide are spaced a distance, and the waterproof that has rubber on the wire drawing pillar therebetween emits 6.
During work, CD-ROM drive motor drives the rotation of silk wheel by driving-disc and drives wire drawing, drive the fixture block that is fixed on the middle hinge by wire drawing again and move, and guarantee the track of its operation, thereby realize the electric operation of slide by mechanisms such as guide wheel and wheel frames together with middle hinge.
CD-ROM drive motor is positioned at the position of the other end of the attached rail of middle guide near the D post, and the outlet direction of CD-ROM drive motor and the moving line of middle hinge are unanimous on the whole, do not need painstakingly to adjust the direction of wire drawing.Therefore, simple in structure, reduce the slide resistance of motion, reduced cost, saved the inner arrangement space that CD-ROM drive motor is installed of slide simultaneously.
