Description

A kind of car door inner board structure

Technical field

This utility model relates to auto Body Technology field, particularly relates to the inner plate structure of a kind of arrangements for automotive doors。

Background technology

At present, interior panel material conventional on automobile is steel plate, and it has the advantages such as resistance to punching press, good moldability, but it is because of the reason of material simultaneously, causes that the weight of himself is also relatively larger, and then makes the weight of car load relatively larger。

And along with, in automotive field, the continuous propelling of Lightweight Technology, use steel inner panel just seems more and more outdated。Therefore, the high-end leading brand of some in field, such as Audi, BMW, Jaguar, benz etc., begin with aluminum alloy materials, manufacture inner plate of car door。

Aluminum alloy materials, lighter than steel material in himself weight, but its mouldability is poorer than steel plate。Therefore, in order to solve the problem of its stamping cracking, generally by into two pieces for inner panel or multi-disc, formation problems can be solved by reducing sheet size and reduction press depth, at the formation car door inner board that is stitched together after each molding。

Specifically, a kind of conventional scheme solving punching press problem is as shown in Figure 3,4, by the inner panel of traditional integrated punching, to cut into the two panels that press depth is very shallow: inner ring main board 301 and outer ring lateral frame board 302, and it is at dress seal area cutting inner panel。In order to ensure car door performance, outer ring lateral frame board 302 adopts the aluminium sheet that material is thicker, and inner ring main board 301 then adopts the thick relatively thin aluminium sheet of material, then passes through riveted joint or resistance spot welding technique, two panels is being spliced into complete inner plate of car door 303。

Although such scheme solves aluminum alloy materials and makes the problem of inner plate of car door stamping cracking, and has ultimately formed a lighter inner plate of car door of deadweight。But the inner plate of car door of this kind of splicing, the shortcoming of its structure also ratio is more prominent。

First, in order to meet car door performance, generally to strengthen in hinge, stop, lock installation region。The solution of such scheme is, outer ring frame plate 302 is adopted thicker aluminum alloy plate materials。Although so meeting car door performance, but the region that need not strengthen also using thicker sheet material, cause surdimensionnement, and also be add car door weight to a certain extent。

Secondly, the splicing between outer ring frame plate 302 and inner ring main board 301, is adopt the rivet of a whole circle or resistance electric welding to connect, and rivet or solder joint 304 quantity of use are many so that manufacturing price is expensive。

3rd, outer ring frame plate 302 stampings ratio is big, and stock utilization is low, causes resource and cost waste。

Therefore, necessary, research and develop a kind of novel car door inner board structure, overcome defect of the prior art。

Utility model content

The purpose of this utility model is in that to provide a kind of novel car door inner board structure, and it is while reducing deadweight, moreover it is possible to meet the performance requirement of car door。

To achieve these goals, the technical solution adopted in the utility model is as follows。

A kind of car door inner board structure, it includes splice plate under main board and side, and under wherein said side, splice plate assembly is fixed on the side lower part of described main board。

Further, in the technical solution of the utility model, also including lock section and strengthen plate, splicing is fixed on the lockset installation position of described main board。

Further, in the technical solution of the utility model, splice plate is provided with under described side hinge installation portion。

Further, in the technical solution of the utility model, splice plate is provided with under described side stop installation portion。

Relative to prior art, the beneficial effects of the utility model are: the inner plate of car door structure that this utility model adopts, its splicing part only splices a piece of inner panel in a bit of region, but not of the prior art one whole circle splicing, and then more cheap resistance spot welding mode can be adopted to splice, and solder joint is less, thus reduce manufacturing cost。It addition, compare with a traditional ring type dividing method, this programme can also be greatly improved stock utilization, promotes observable index。

Further, single piece type inner panel is divided into two panels, substantially improves punching formation property。And, the split position of two panels inner plate structure can need arbitrarily segmentation according to actual strength, more flexible than the line segmentation of conventional steel inner panel；Meanwhile, only adopting, in the region that Structural strength calls is high, the sheet material that material is thicker, other regions material is thick relatively thin, it is possible to increase weight efficiency, better realizes lightweight。

Finally, the splicing regions of two pieces of inner panels is in the inside of inner plate of car door, and trim panel can cover splicing feature after installing, it is achieved better perceived quality。

Detailed description of the invention

Below with reference to drawings and Examples, the technical scheme of a kind of car door inner board structure that this utility model is related to is described in further detail。

Refer to Fig. 1, shown in 2, the embodiment that this utility model relates to provides a kind of car door inner board structure 201, and it includes splice plate 101 and lock section under main board 103, side and strengthens plate 104。

Under wherein said side, splice plate 101 assembly is fixed on the side lower part of described main board 103, and plate 104 is strengthened in described lock section, and splicing is fixed on the lockset installation position of described main board 103。

This utility model makes existing single piece type steel inner panel into two-piece type splicing construction inner panel, such that it is able to adopt lighter aluminum alloy materials of conducting oneself with dignity, and two-piece type splicing construction simultaneously, moreover it is possible to be substantially improved the punching formation property of every aluminum alloy materials splicing construction。

And, the split position of two panels inner plate structure can need arbitrarily segmentation according to actual strength, more flexible than the line segmentation of conventional steel inner panel；Meanwhile, only adopt, in the region that Structural strength calls is high, the sheet material that material is thicker, for instance, it is provided with splice plate 101 under the side of hinge, stop installation portion 102, and other regions material is thick relatively thin, so can improve weight efficiency, better realize lightweight。

Further, the splicing part of two panels inner panel only splices in a bit of region, but not the splicing of a whole ring type of the prior art, and then more cheap resistance spot welding mode can be adopted to splice, and solder joint 202 is less, thus reducing manufacturing cost。It addition, compare with conventional segmentation methods, this programme can also be greatly improved stock utilization, promotes observable index。

Technical scope of the present utility model is not limited solely to the content in described above, those skilled in the art can under the premise without departing from this utility model technological thought, above-described embodiment is carried out various deformation and amendment, and these deformation and amendment all should be worked as and belonged in scope of the present utility model。
