Abstract
The utility model discloses a transmission mechanism of an electric angle adjuster. The electric angle adjuster comprises a driving shaft. The transmission mechanism comprises an electric motor and a force transferring rod, wherein the force transferring rod is a hollow rod; the cross section of the force transferring rod is shaped like a star with a plurality of convex angles; the driving shaft is provided with a central hole and is sheathed on the force transferring rod; the shape of the central hole of the driving shaft is matched with that of the cross section of the force transferring rod; and the electric motor is in transmission connection with the force transferring rod. Preferably, the electric motor adopts a hollow-shaft motor, the force transferring rod penetrates through the hollow-shaft motor, and the shape of an inner hole of the hollow-shaft motor is matched with that of the cross section of the force transferring rod. The transmission mechanism adopts the hollow rod with the star-shaped section to drive the angle adjuster to rotate so as to form a torsion transmission structure of a similar spline shaft, so that not only is the structure simple, and is the weight light, but also the transmission reliability is greatly improved. Further, the hollow-shaft motor is adopted to be connected with the force transferring rod directly, so that the transmission mechanism is more compact, the quantity of parts is reduced and the deformation of the force transferring rod is reduced.
Description
Technical field
The utility model relates to the angle regulator of seat, is specifically related to a kind of transmission device of electronic recliner.
Background technology
Seat angle adjustor is used for the angle of adjustment seat chair back, to satisfy occupant's safety, comfortable sitting posture requirement.Disclose a kind of seat angle adjustor such as Chinese utility model patent CN201296189Y, comprise with lower member: internal gear has central boss; Outer tooth plate is meshed with internal gear prejudicially, and this outer tooth plate has center flange, centre hole and internal spline, and described internal spline is positioned at the periphery of center flange; Eccentric voussoir, turn outside between tooth plate centre hole and the internal gear central boss; Axle drive shaft has first pushing block and second pushing block, and first pushing block can contact and drive eccentric voussoir and rotate with eccentric voussoir; Described eccentric voussoir is the circular arc cylinder with outer tooth plate centre hole, the contacted surface of internal gear central boss; Also comprise a locking spring, it has an elastic collar and bayonet socket, block, and described elastic collar is enclosed within on the outer tooth plate center flange, and described bayonet socket inserts in the described internal spline, and described block can contact with second pushing block of axle drive shaft.When drive shaft turns, can drive relatively rotating between the inside and outside tooth plate, thereby realize adjusting the back of seat angle.
Yet in the prior art, the transmission device more complicated, the reliability that order about the drive shaft turns of recliner also await further perfect.
The utility model content
The technical problems to be solved in the utility model provides a kind of transmission device of electronic recliner, to overcome the above-mentioned defective of prior art.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of transmission device of electronic recliner, described recliner comprises an axle drive shaft, described transmission device comprises an electrical motor and a dowel bar, described dowel bar is a hollow stem, the cross-sectional plane of dowel bar is the star with a plurality of salient angles, described axle drive shaft has a centre hole and is enclosed within on the dowel bar, the shape in described shaft center hole and the shape of cross section of dowel bar are complementary, and described electrical motor and dowel bar are in transmission connection.
Preferably, described electrical motor is a hollow shaft motor, and described dowel bar runs through described hollow shaft motor, and the shape of hollow shaft motor endoporus and the shape of cross section of dowel bar are complementary.
Preferably, the cross-sectional plane of described dowel bar is a hexagram.
Preferably, described dowel bar is made by shape steel tube.
Preferably, the two ends of described dowel bar are fixed with back-up ring.
The utility model adopts the hollow stem of star cross section to drive recliner and rotates, can simplify the connection structure of dowel bar and recliner axle drive shaft, form a kind of torque transfer arrangement of similar castellated shaft, not only simple in structure, in light weight, and also the reliability of transmission also improves greatly.Further, adopt hollow shaft motor directly to link to each other, can make transmission device compact more, reduce number of parts, reduce the distortion of dowel bar with dowel bar.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the scheme drawing of the transmission device of the electronic recliner of the utility model.
Fig. 2 is the scheme drawing of dowel bar cross-sectional plane.
The specific embodiment
As shown in Figure 1, the transmission device of the electronic recliner of the utility model, described transmission device comprise an electrical motor 2 and a dowel bar 3, and dowel bar 3 is a hollow stem.As shown in Figure 2, the cross-sectional plane of dowel bar 3 is the star with a plurality of salient angles 31, is hexagram in the present embodiment, and from appearance, dowel bar 3 has the elongate rod of many fins for the surface.Preferably, dowel bar 3 is made by shape steel tube.
As shown in Figure 1, the axle drive shaft 1 of recliner just is enclosed within on the dowel bar 3, the shape of this axle drive shaft 1 centre hole and the shape of cross section of dowel bar 3 are complementary, make axle drive shaft 1 on dowel bar 3, to endwisely slip, but can not relatively rotate, form a kind of similar spline bonded assembly matching relationship between axle drive shaft 1 and the dowel bar 3 thereby make, be used for transfer torque.
In the present embodiment, electrical motor 2 adopts hollow shaft motor, just has an endoporus that axially connects on the motor output shaft, dowel bar 3 runs through this hollow shaft motor vertically, the interior hole shape of hollow shaft motor and the shape of cross section of dowel bar 3 are complementary, also form a kind of similar spline bonded assembly matching relationship, be used for transfer torque.Certainly, electrical motor 2 also can adopt the solid axle motor, and is in transmission connection by known mechanisms such as gear transmission and dowel bar, to dowel bar 3 transfer torques.
After electrical motor, recliner and dowel bar connect,, be used for axial limiting at the two ends of dowel bar fixed installation back-up ring 4.Like this, electrical motor 2 drives dowel bar 3 and rotates, and the axle drive shaft 1 that dowel bar 3 drives recliner again rotates the angle of coming the adjustment seat chair back.
