Abstract
The invention discloses an automobile seat adjusting dowel bar, which comprises a dowel bar, wherein splines are arranged outside the dowel bar, an inner hole is formed in the center of the dowel bar, and the shape of the inner hole is the same as that of the cross section of the dowel bar; the length a of the force transmission rod is 400-600 mm; the cross section has three shapes of irregular six-key shape, five-key shape and regular six-key shape. The automobile seat adjusting dowel bar reduces the consumption of raw materials, lightens the dead weight of an automobile body, saves the oil consumption of an automobile and has considerable economic and social benefits under the condition of increasing the precision and the strength of a product.
Description
Technical field
The present invention relates to a kind of auto parts and components, especially relate to a kind of automotive seat that are used for automobile and regulate dowel bar.
Background technology
The seat adjustment dowel bar mainly connects seat angle adjustor and motor, is used for the adjusting of back of seat angle, strengthens the traveling comfort of seat for the occupant.The automobile dowel bar is of a great variety at present, but the overwhelming majority all is solid, and the cross sectional shape of two mating part has six prismatics, eight prismatics, square or the like; This traditional dowel bar processing technology is complicated; And because part itself is heavier, increased raw materials consumption greatly, also increased vehicle body deadweight and vehicle oil consumption; Face exhausted today in global natural resources continuous decrease, the mode of this high energy consumption has been run counter to energy-saving and cost-reducing aim.Also has a kind of follow-on dowel bar in addition; It is special-shaped material in the welding of the two ends of hollow circular-tube; This mode has reduced the weight of part, but has also caused the reduction of product precision and the decline of torsional performance, because the product space degree error that welding process itself is determined is bigger; The yield strength out of reach limit test requirement of hollow circular-tube simultaneously is so this dowel bar only is used on some low end vehicle at present.
Summary of the invention
Technical matters to be solved by this invention provides a kind of light-high-strength automotive seat and regulates dowel bar.
In order to solve the problems of the technologies described above; The present invention realizes through following technical scheme: this automotive seat are regulated dowel bar, comprise dowel bar, and said dowel bar outer setting has spline; The center is provided with endoporus, and the shape of endoporus is identical with said dowel bar shape of cross section.
Further, the length a of said dowel bar is 400～600mm.
Further, said dowel bar shape of cross section has three kinds of irregular six key shapes, five key shapes and regular six key shapes.
Said irregular six key shape dowel bar cross-sectional diameter b are 10.4mm, and spline width d is 2.2mm, and keyway diameter c is 8.5mm.
Said five key shape dowel bar cross-sectional diameter b ' are 10.1mm, and spline width d ' is 2.7mm, and keyway diameter c ' is 8.5mm.
Said regular six key shape dowel bar cross-sectional diameter b " be 10.1mm, spline width d " be 2.7mm, keyway diameter c " be 8.5mm.
Compared with prior art; Usefulness of the present invention is: this automotive seat are regulated dowel bar under the situation that increases product precision, intensity; Reduced raw-material consumption, alleviated the vehicle body deadweight, saved the automobile consumption of fuel, economic benefit and social benefit are very considerable.
Description of drawings:
Below in conjunction with accompanying drawing the present invention is further specified.
Fig. 1 is that a kind of automotive seat of the present invention are regulated the dowel bar side schematic view;
Fig. 2 is that the irregular six key shape automotive seat of the present invention are regulated the dowel bar cross sectional representation;
Fig. 3 is that the present invention's five key shape automotive seat are regulated the dowel bar cross sectional representation;
Fig. 4 is that the present invention's rule six key shape automotive seat are regulated the dowel bar cross sectional representation.
Among the figure: 1, dowel bar; 2, spline; 3, endoporus.
The specific embodiment:
Describe the present invention below in conjunction with the accompanying drawing and the specific embodiment:
A kind of automotive seat are regulated dowel bar shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 4, comprise dowel bar 1, and said dowel bar 1 outer setting has spline 2, and the center is provided with endoporus 3, and the shape of endoporus 3 is identical with said dowel bar 1 shape of cross section; Dowel bar 1 shape of cross section has three kinds of irregular six key shapes, five key shapes and regular six key shapes; As shown in Figure 1, the length a of said dowel bar 1 is 400～600mm; See also Fig. 2, said irregular six key shape dowel bar cross-sectional diameter b are 10.4mm, and spline 2 width d are 2.2mm, and keyway diameter c is 8.5mm; See also Fig. 3, said five key shape dowel bar cross-sectional diameter b ' are 10.1mm, and spline 2 width d ' are 2.7mm, and keyway diameter c ' is 8.5mm; See also Fig. 4, said regular six key shape dowel bar cross-sectional diameter b " be 10.1mm, spline 2 width d " be 2.7mm, keyway diameter c " be 8.5mm.
This automotive seat are regulated dowel bar and are adopted metal cold extrusion forming technology; Choose the cold-strip steel of regulation, on pepe welder, weld, pull out circle then; Re-use the spline-shaped that the particular manufacturing craft draw becomes regulation; Cut into required length at last, two chamfering, the surface carries out being final products behind the bonderization; During work, automotive seat are regulated in the top spline in river in the keyway that the a/s direction of dowel bar inserts drive wheel, loaded onto collar and fix, starter motor can drive the adjusting that recliner is carried out backrest angle.
It is emphasized that: above only is preferred embodiment of the present invention; Be not that the present invention is done any pro forma restriction; Every foundation technical spirit of the present invention all still belongs in the scope of technical scheme of the present invention any simple modification, equivalent variations and modification that above embodiment did.
