Fig. 1 is the hinge pillar schematic diagram of a kind of preferred power actuated vehicle of the utility model;

Fig. 2 is the decomposing schematic representation of the hinge pillar of the power actuated vehicle shown in Fig. 1.

Detailed description of the invention

Below in conjunction with accompanying drawing, a preferred embodiment of the present utility model is described in detail.The identical Reference numeral of wherein identical parts represents.It should be noted that, the word "front", "rear" of use is described below, "left", "right", "up" and "down" refer to direction in accompanying drawing, word " interior " and " outward " refer to the direction towards or away from particular elements geometric centre respectively.

As depicted in figs. 1 and 2, the hinge pillar of the power actuated vehicle that the utility model provides comprises the hinge pillar body 1 be connected with power actuated vehicle front side member, described hinge pillar body 1 is also connected with extension board 2, described extension board 2 overlaps with the sill plate of power actuated vehicle, as shown in Figure 2, L-type hinge pillar is formed on the bottom that described extension board 2 is welded on described hinge pillar body 1, namely, described hinge pillar body 1 is the vertical first half of described L-type hinge pillar, described extension board is the horizontal bottom of described L-type hinge pillar, the length of the extension board 2 of the present embodiment is preferably 150mm-250mm, certainly, those skilled in the art can also require to do accommodation to the length of described extension board 2 according to safety performance, repeat no more herein.

In order to meet the intensity needs of described hinge pillar, reduce thickness and the weight of hinge pillar body 1 and extension board 2, the high strength steel that hinge pillar body 1 of the present utility model and extension board 2 adopt yield strength to be greater than 210MPa is made simultaneously.

L-type hinge pillar of the prior art is formed in one structure, and therefore, there is the region by both direction stress in the corner of described L-type structure, therefore, in its forming process, corner easily produces problem of Cracking.The hinge pillar that the utility model provides is L-type structure, and as shown in Figure 1, described hinge pillar body 1 is close to oblong, described rectangular hinge pillar body 1 is when shaping, there is not the region by both direction tensile stress, therefore, it is possible to effectively avoid the problem of this body formed cracking of hinge pillar.Similarly, described extension board 2 similarly eliminates the region by both direction tensile stress when shaping, therefore, can avoid the problem of the shaping cracking of extension board equally.Described hinge pillar body 1 and described extension board 2 can need according to respective intensity and thickness the steel preparation adopting identical or different yield strength respectively, then by welding, described hinge pillar body 1 and described extension board 2 are fixed together, thus on the basis meeting hinge pillar requirement of strength, reduce the requirement of the elongation to high strength steel, effectively can also reduce weight and the productive costs of hinge pillar simultaneously.

In addition, the rectangular hinge pillar body 1 that the utility model provides and extension board 2, compared with L-type hinge pillar of the prior art, can effectively improve part material degree of utilization, what those skilled in the art should understand that is, steel plate is utilized to prepare the structure of L-type, the degree of utilization of steel plate is on the low side, larger space will inevitably be retained down between the structure of L-type, therefore more waste material can be produced, thus cause cost to raise, and the hinge pillar body 1 that the utility model provides and extension board 2 are all close to oblong, therefore, it is possible to utilize material more fully, reduce unnecessary waste of material, thus reach the object reduced costs.

As a kind of preferred version of the present utility model, the high strength steel that the hinge pillar body 1 of the present embodiment preferably adopts yield strength to be greater than 550MPa is made, the high strength steel that yield strength is greater than 550MPa can ensure hinge pillar main body requirement of strength effectively, on this basis, the steel that the hinge pillar body 1 of the present embodiment can be preferably 1mm-1.2mm by thickness are made, to obtain the effect of the weight reducing hinge pillar body 1, and then realize the object reducing productive costs.Visible, the present embodiment prepares hinge pillar by adopting high strength steel welding, not only meets the requirement of strength of hinge pillar, can also reduce the requirement of the elongation to high strength steel, achieve simultaneously and reduce the weight of hinge pillar and the object of productive costs.Consider the stressed and requirement of strength of described extension board 2, the extension board 2 of the present embodiment preferably adopts yield strength to be that the high strength steel of 210-550MPa is made, and the thickness of described extension board 2 can be able to require to select according to vehicle security.

Those skilled in the art it should be noted, hinge pillar body 1 in above-described embodiment and the yield strength of extension board 2 and thickness are only a kind of preferred versions of the present utility model, those skilled in the art can also according to security needs, adopt the steel plate with more high-yield strength to prepare described hinge pillar body 1 and extension board 2, thus realize reducing the weight of hinge pillar and the object of productive costs further, repeat no more herein.

As a kind of preferred version of the present utility model, the hinge pillar body 1 of the present embodiment and described extension board 2 are respectively arranged with two face of weld, described two face of weld are arranged on described hinge pillar body 1 and described extension board 2 coupling end, and make two joint faces mutually vertical preferably by this coupling end of bending, the connection mode of two face of weld can ensure fastness and the reliability of described hinge pillar body 1 and described extension board 2 effectively.During assembling, two face of weld of described hinge pillar body 1 overlap with two face of weld of described extension board 2 respectively, then, by Pressure Welding by two face of weld of described hinge pillar body 1 respectively with two face of weld weld togethers of described extension board 2, finally realizing described hinge pillar body 1 and described extension board 2 to be fixed together forms the hinge pillar of L-type.Certainly, the above-mentioned mode for being welded to connect described hinge pillar body 1 and described extension board 2 is only a kind of preferred version of the present utility model, the utility model can need to select other welding manner known in those skilled in the art according to the assembling of reality, repeats no more herein.

Last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the scope of each embodiment technical scheme of the utility model.
