The specific embodiment

Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used for explaining the utility model, is not be used to limiting scope of the present utility model.

As depicted in figs. 1 and 2, in the prior art, vehicle chair framework comprises seat cushion framework 100 and backrest frames 200, the main support frame of seat cushion framework 100 and backrest frames 200 all is to adopt bend pipe 400 to consist of, and welds punching press sheet metal component 300 on the main support frame of seat cushion framework 100 and backrest frames 200 again.Consider the materials rate of bend pipe 400 tubing, as shown in Figure 2, generally are connected a part of tubing excision that the place that connects can be overlapping with punching press sheet metal component 300 with the punching press sheet metal component at bend pipe 400, thereby the planeness that has caused bend pipe 400 is difficult to guarantee, when cushion frame is done the Static and dynamic strength test, cushion frame begins distortion, fracture from bend pipe 400 with punching press sheet metal component 300 lap-joints, can't satisfy the requirement of strength of cushion frame.

In order to address the above problem, the utility model provides a kind of vehicle chair framework, it comprises seat cushion framework 100 and backrest frames 200, and the main support frame of seat cushion framework 100 and backrest frames 200 also is to adopt bend pipe 400 to consist of, and is welded with punching press sheet metal component 300 at bend pipe 400.The punching press sheet metal component 300 that arranges at the seat adjuster place in Fig. 1 is as example, can be divided into two sections pipeline sections with the bend pipe 400 of punching press sheet metal component 300 overlap joints, i.e. the first pipeline section 401 and the second pipeline section 402, wherein, the first end of the first pipeline section 401 and punching press sheet metal component 300 overlap joints, the second end of the second pipeline section 402 and punching press sheet metal component 300 overlap joints, as shown in Figure 3, the first end of the first pipeline section 401 has one section external diameter less than the draw structure 401a of the internal diameter of the second end of the second pipeline section 402; As shown in Figure 4, the draw structure 401a of the first pipeline section 401 interts in the second end that accesses the second pipeline section 402, and and the second end of the second pipeline section 402 between weld; As shown in Figure 5, punching press sheet metal component 300 adopts welding manner to be overlapped on the outside (a namely represents solder joint among Fig. 5) of the second end of first end, second pipeline section 402 of the first pipeline section 401 again.

Vehicle chair framework of the present utility model lengthens pipeline section, intert and dock and welding manner by this, guaranteed the planeness of bend pipe 400, and increase the bending strength of bend pipe 400 itself, reach under the prerequisite that drops into least cost, increase the intensity of bend pipe 400 with punching press sheet metal component 300 lap-joints, in the situation that decreasing cost, weight are successively decreased, increased the due intensity of cushion frame thereby satisfy cushion frame.

In the present embodiment, preferred, the length of draw structure 401a is 20 ~ 25mm.

In the present embodiment, preferably, the bend pipe 400 that consists of the main support frame of seat cushion framework 100 and backrest frames 200 is pipe, namely, the first pipeline section 401 and the second pipeline section 402 are circular tube structure, draw structure 401a processes the circular tube structure that obtains through the draw, and draw structure 401a is consistent with the axial line of the second end of the second pipeline section 402.

Need to prove, punching press panel beating plate herein not only be confined to as shown in Figure 1 at the seat adjuster place, can also be arranged on the punching press sheet metal component 300 of seat cushion framework 100 and backrest frames 200 other positions, correspondingly, two sections pipeline sections that the punching press sheet metal component 300 of bend pipe 400 in other positions overlaps can adopt equally and aforesaidly pipeline section is lengthened, interts docking connect with welding manner, and guarantee that bend pipe 400 and the lap-joint of punching press sheet metal component 300 are difficult for deformation and fracture.

The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
