Abstract
The utility model relates to a transmission device for a sliding door of an automobile, comprising a middle hinge, inhaul cables, a slideway and a motor transmission part, wherein the inhaul cables comprise a front inhaul cable and a rear inhaul cable which are connected at two sides of the hinge; the power output end of the motor transmission part is connected with the inhaul cables; connectors are connected at the head parts of the inhaul cables; connecting parts are arranged on the inhaul cables, close to the connectors; and the connectors are connected on the middle hinge. The transmission device for the sliding door of the automobile is characterized in that spherical grooves are arranged in the connectors; correspondingly, a rotating mechanism is a ball head which is adaptive to the spherical grooves; and the ball head is fixedly connected with the middle hinge. Compared with the prior art, the transmission device for the sliding door of the automobile has the advantages that under the state that the middle hinge is positioned at the turning part of the slideway, as the connectors are movably matched with the ball head, the connectors rotate relative to the middle hinge and turn conveniently with same radian as that of the slideway, therefore, the connecting parts generate no bending, and long-time stable running is guaranteed.
Description
Technical field
The utility model relates to a kind of automobile sliding door driving device, relates in particular to the connection structure of a kind of automobile sliding door and drag-line.
Background technology
Slide driving device in the existing motorcar electric, as shown in Figure 1, hinge 1a, fore stay 2a, back stay 3a, guide holder 7a, slideway 4a, track adjusting wheel 71a, motor transmission part 5a in generally comprising, 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 of the drag-line that is used to lead, motor transmission part 5a is contained between the car gusset of automobile, motor transmission part 5a drives drag-line and moves forward and backward, thereby realizes the slide auto-switch function.As shown in Figure 2, Cable head 6a and middle hinge 1a ways of connecting adopt die casting T-shape head to be connected with adapter plate 11a open slot on the middle hinge, this structure design is simple, and used for many years, but when central hinge 1a runs to middle slideway 4a corner, because Cable head 6a is captiveed joint 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 influence is normal.
The utility model content
Technical problem to be solved in the utility model is not make connecting portion produce the automobile sliding door driving device of bending when providing a kind of connector to turn round with middle hinge at the above-mentioned state of the art.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of automobile sliding door driving device, comprise middle hinge, drag-line, slideway and motor transmission part, aforesaid drag-line comprises fore stay and the back stay that is 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 then is connected on the middle hinge, it is characterized in that having ball recess in the described connector, accordingly, described rotating mechanism be one with the adaptive bulb of aforementioned ball recess, this bulb is captiveed joint with middle hinge.
For making clamping firmly with easy to assembly, described bulb bottom has a columnar portion, and, this columnar portion radical length is less than the bulb radius, described ball recess inwall bottom has an annular caulking groove, and a jump ring is located in the aforesaid annular caulking groove and is connected in aforesaid columnar portion and with connector and bulb flexible connection.
Compared with prior art, advantage of the present utility model is: middle hinge is positioned under the state of slideway corner, because connector cooperates for movable with bulb, the middle relatively 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, guarantees permanent smooth operation; Integral structure is simple, and is easy for installation, respond well.

The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Automobile sliding door driving device in the present embodiment comprises middle hinge, drag-line 2, slideway and motor transmission part, drag-line 2 comprises fore stay and the back stay that is connected in middle hinge both sides, the motor transmission part clutch end is connected with drag-line, the head of drag-line 2 is provided with connector 6, drag-line 2 has connecting portion 61 (with reference to figure 5) near connector 6, on the hinge 4, connector 6 flexibly connected by a rotating mechanism with middle hinge 4 during 6 of this connectors were connected in.As shown in Figure 4, have ball recess 12 in the connector 6, accordingly, rotating mechanism is a bulb 3 adaptive with ball recess 12, and this bulb 3 is captiveed joint with middle hinge 4.
Further, bulb 3 bottoms have a columnar portion 31, and these columnar portion 31 radical lengths are less than bulb 3 radiuses, ball recess 12 inwall bottoms have annular caulking groove 11, one jump rings 7 and are located in the annular caulking groove 11 and are connected in columnar portion 31 and connector 6 and bulb 3 are flexibly connected.On the hinge, adapter plate 5 and middle hinge 4 can design in split, also can be one-body molded during bulb 3 was arranged at by adapter plate 5.
Only need firmly connector 6 be pressed in the bulb 3 during installation, connector 6 just can not be extracted easily, but can freely rotate around bulb.
As shown in Figure 5, in hinge 4 be positioned under the slideway 8 corner states because connector 6 and bulb 3 cooperate for activity, connector 6 relative in hinge 4 rotate and maintenance and slideway 8 the same radians and take advantage of a situation and turn round, thereby connecting portion 61 does not produce bending, guarantees permanent smooth operation.
