Abstract
The invention discloses a splitting structure for a vehicle door inner plate, belongs to the field of door structures for passenger vehicles and aims to solve the problem of high cost due to the need of opening a die once again for the vehicle door inner plate when the structure of a vehicle door outer plate is changed. In the splitting structure for the vehicle door inner plate, a front connecting plate (3) and a back connecting plate (4) are fixedly connected to the left and right sides of a vehicle door inner plate (1) respectively; the front connecting plate (3) and the back connecting plate (4) are covered together with both sides of the vehicle door inner plate (1) respectively. According to the splitting structure, the front and back connecting plates are arranged, so that the die of the vehicle door inner plate does not need to be opened under the condition that the shape of the vehicle door outer plate is changed, the shape of the vehicle door outer plate can be changed without influencing the metal plate structure of the vehicle door inner plate, and the development cost is further reduced.
Description
Technical field
The present invention relates to a kind of improved automobile door structure, specifically, is a kind of improvement structure about inner plate of car door.
Background technology
Along with the development ，Ge great producer of auto trade all at the novel automobile of research and development design to adapt to client's multiple demands.Thereby the external form of automobile door plate also changes occurring.In modern automobile industry, passenger car door generally adopts monoblock panel beating to carry out laser assembly solder as inner panel or the different panel beating of two bulk strengths, during with external door panel bound edge, pass through inner panel bound edge, but when external form changes and causes door skin alteration of form in vehicle research and development, need to manufacture the inner panel shape that makes new advances to adapt to outside plate, thereby cause again making new inner plate of car door mould, because inner plate of car door is larger, the die sinking time also can be long, increases R&D costs and time, causes inconvenience.
Summary of the invention
For above shortcomings in prior art, the invention provides a kind of inner plate of car door that can reduce die sinking time and cost and split structure.
For realizing above-mentioned technical purpose, the technical solution used in the present invention is as follows:
Inner plate of car door splits a structure, comprises door skin and inner plate of car door, and the described inner plate of car door left and right sides is fixedly connected with respectively front connecting panel and rear connecting panel, and this front connecting panel and rear connecting panel carry out bound edge with door skin both sides respectively.
Adopt the inner plate of car door of technique scheme to split structure, when door skin shape mainly changes in both sides, do not need again the shape die sinking for inner plate of car door, but only to being connected to the forward and backward connecting panel of inner plate of car door both sides, carry out die sinking, after this forward and backward connecting panel is fixedly connected with inner plate of car door can just with door skin form fit.Because forward and backward connecting panel is less, than the die sinking again of inner plate of car door, can save die sinking time and die cost.
Furthermore, described door skin rear inside is laterally provided with anti-collision beam, and described inner plate of car door front end inner side is provided with brace panel.Anti-collision beam can be strengthened the intensity of door skin rear end, and brace panel can be strengthened the intensity of inner plate of car door front end.
Furthermore, described front connecting panel and rear connecting panel respectively with inner plate of car door welded lap.The mode of welded lap overlaps easily, and solder joint is little, and welding value of thrust is relatively good.
The present invention compared to existing technology, by increasing forward and backward connecting panel, making to change shape at door skin does not need little in the situation that again inner plate of car door die sinking, and therefore changing door skin moulding can not have influence on inner plate of car door sheet metal structural yet, has reduced development cost.
Accompanying drawing explanation
Fig. 1 is package assembly schematic diagram of the present invention;
Fig. 2 is the back view after splitting structure shown in Fig. 1 and assembling;
Fig. 3 is that X-X shown in Fig. 2 is to cross-sectional view;
Fig. 4 a, 4b, 4c and 4d are respectively A in Fig. 3, B, C and D place enlarged diagram;
Fig. 5 is that Y-Y shown in Fig. 2 is to cross-sectional view.
The specific embodiment
In order to make those skilled in the art, the present invention may be better understood, below in conjunction with drawings and Examples, technical solution of the present invention further illustrated.
As depicted in figs. 1 and 2, a kind of inner plate of car door splits structure, comprises door skin 2 and inner plate of car door 1, and inner plate of car door 1 left and right sides connects respectively front connecting panel 3 and rear connecting panel 4.As shown in Figure 3, described front connecting panel 3 and rear connecting panel 4 carry out bound edge with door skin 2 both sides respectively, and concrete both sides binding structure can be found out from Fig. 4 a and Fig. 4 c, as Fig. 4 b, shown in 4d, front connecting panel 3 is connected with the mode of inner plate of car door 2 by welded lap respectively with rear connecting panel 4.
In Fig. 3, also show the anti-collision beam 5 that is arranged on door skin 2 inner sides, this anti-collision beam 5 is positioned at door skin 2 rear ends, its role is to improve the intensity of door skin 2, in inner plate of car door 1 front end inner side, be also provided with brace panel 6, for improving the intensity of inner plate of car door 1 front end.Due to anti-collision beam 5 and 6 weak location that are arranged on car door of brace panel, so also alleviated car door overall weight.
Inner plate of car door structure provided by the invention, tool has the following advantages: when door skin 2 shapes change, do not need again the shape die sinking for inner plate of car door 1, but only for the front connecting panel 3 and the rear connecting panel 4 that are connected to inner plate of car door 1 both sides, carry out die sinking, after the forward and backward connecting panel 3,4 and door skin 2 form fit of making like this, carry out bound edge with door skin 2.Due to front connecting panel 3 and rear connecting panel 4 less, than the die sinking again of inner plate of car door 1, not only can not have influence on the structure of inner plate of car door 1 panel beating, also save die sinking time and die cost.
The present invention just changes and can not mate the improvement that door skin carries out for inner plate of car door structure on two sides, and main application changes with inner plate of car door both sides profile, and other parts change little situation.When if inner plate of car door upper and lower end also exists the larger alteration of form that can not mate door skin, the electric appliance general part of all inside all needs to rearrange and develop, and therefore this situation can not adopt the method identical with splitting structure described in the application.
Above a kind of inner plate of car door provided by the invention being split to structure is described in detail.The explanation of specific embodiment is just for helping to understand method of the present invention and core concept thereof.It should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also carry out some improvement and modification to the present invention, these improvement and modification also fall in the protection domain of the claims in the present invention.
