Abstract
The utility model discloses a kind of new longeron closing plate structure, including longitudinal beam structure part and closing plate structure part, it is cavernous structure corresponding with longitudinal beam structure part among closing plate structure part, the flange of longitudinal beam structure part side is provided with the closing plate structure part positioned at the edge of its cavernous structure, the flange is located in the cavity of longitudinal beam structure part and is fixedly connected with longitudinal beam structure part.The utility model, which belongs to part connecting structure, to be changed, and the effect for reducing cost has been reached on the premise of switching performance is not influenceed.
Description
Technical field
It the utility model is related to automobile longitudinal girder, and in particular to a kind of new longeron closing plate structure.
Background technology
Automobile longitudinal beam structure part has mechanical property requirements, it will usually which it is closing plate structure part mode closing chamber to use increase part
Body, increase intensity.And it is because anticorrosive antirust requires, is cavernous structure among longeron shrouding part.
The longeron closing plate structure of existing automobile is as shown in figure 1, longitudinal beam structure part 2 is outside close to one end of closing plate structure part 1
Extension is bent to form the joint face 3 that be connected with closing plate structure part 1, and the joint face in this kind of mode on longitudinal beam structure part 2 is using drawing
Prolong technique, die cost is high, and Material Cost is high.
Utility model content
The utility model is in order to solve weak point of the prior art, there is provided a kind of new longeron closing plate structure, not
Influence to have reached the effect for reducing cost on the premise of switching performance.
In order to solve the above technical problems, the utility model adopts the following technical scheme that：A kind of new longeron closing plate structure, bag
Include longitudinal beam structure part and closing plate structure part, be cavernous structure corresponding with longitudinal beam structure part among closing plate structure part, the shrouding
The flange of longitudinal beam structure part side is provided with structural member positioned at the edge of its cavernous structure, the flange is located at longeron knot
It is fixedly connected in the cavity of component and with longitudinal beam structure part.
The flange is uniformly laid along the circumferential of the cavernous structure.
The cavernous structure is square hole.
The flange and closing plate structure part are integral type structure.
The beneficial effects of the utility model are：
1. the utility model has reached the effect for reducing cost on the premise of switching performance is not influenceed.
Changed 2. the utility model belongs to part connecting structure, the overlap joint knot of change closing plate structure part and longitudinal beam structure part
Structure, i.e., the joint face of former longitudinal beam structure part are cancelled, closing plate structure part increase joint face（Flange）, type of attachment is constant, mechanical property
Can be same unchanged, mould reduces with Material Cost.
3. because poroid region is scrap area among closing plate structure part, this garbage area is utilized the company of being designed as by the patent
Junction（Flange）, material appearance and size do not increase.And longitudinal beam structure part cancels joint face, material appearance and size is reduced.In addition
Closing plate structure part uses moulding process, and die cost is low, increases process content in inexpensive mould.Longitudinal beam structure part uses drawing
Technique, die cost is high, and process content is reduced in high die cost.The patent realizes that product quality is constant, and product cost obtains
To the purpose of reduction.
Brief description of the drawings
Fig. 1 is the schematic diagram of existing longeron closing plate structure；
Fig. 2 is structural representation of the present utility model；
Fig. 3 is A-A diagrammatic cross-sections in Fig. 2.
Embodiment
Specific embodiment of the present utility model is elaborated below in conjunction with accompanying drawing.
As shown in Figures 2 and 3, a kind of new longeron closing plate structure of the present utility model, including longitudinal beam structure part 2 and shrouding
Structural member 1, the centre of closing plate structure part 1 is cavernous structure 4 corresponding with longitudinal beam structure part 2, is located at it on the closing plate structure part 1
The edge of cavernous structure is provided with the flange 3 of longitudinal beam structure part side, and flange 3 and closing plate structure part 1 are integral type structure,
The flange 3 is located in the cavity of longitudinal beam structure part 2 and is fixedly connected with longitudinal beam structure part 2.
In the present embodiment, the cavernous structure 4 is square hole, circumference uniform cloth of the flange 3 along the cavernous structure 4
If.
Because poroid region is scrap area among closing plate structure part 1, this garbage area is utilized and is designed as connecting by the patent
Face（Flange 3）, material appearance and size do not increase.And longitudinal beam structure part 2 cancels joint face, material appearance and size is reduced.In addition
Closing plate structure part 1 uses moulding process, and die cost is low, increases process content in inexpensive mould.Longitudinal beam structure part 2 is using drawing
Prolong technique, die cost is high, and process content is reduced in high die cost.It is constant that the patent realizes product quality, product cost
The purpose being reduced.
The utility model, which belongs to part connecting structure, to be changed, the overlap joint knot of change closing plate structure part 1 and longitudinal beam structure part 2
Structure, i.e., the joint face of former longitudinal beam structure part 2 are cancelled, and closing plate structure part 1 increases joint face（Flange）, type of attachment is constant, mechanics
Performance is equally unchanged, and mould reduces with Material Cost, has reached reduction on the premise of switching performance is not influenceed so as to realize
The effect of cost.
Above example is only to illustrative and not limiting the technical solution of the utility model, although with reference to above-described embodiment pair
The utility model is described in detail, it will be understood by those within the art that：The utility model can still be entered
Row modification or equivalent substitution, without departing from any modification or partial replacement of spirit and scope of the present utility model, it all should
Cover among right of the present utility model.
