The specific embodiment
For making the technical problems to be solved in the utility model, technical scheme and advantage clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
Fig. 2 represents the application of the utility model automotive front end cross sill on vehicle body, and Fig. 3 is the schematic cross-section along A-A line in Fig. 2.As shown in Figures 2 and 3, the automotive front end cross sill 201 that the utility model embodiment provides comprises microscler cross sill beam body, and the cross-sectional plane of this cross sill beam body closed ring structure that is hollow.
And existing automotive front end cross sill is the semi-closed structure of punching type, this semi-closed structure causes the Rigidity and strength of automotive front end cross sill on the weak side, and solder joint failure and panel beating cracking phenomena often occur in intensive test.Compare with semi-enclosed structure, the cross-sectional structure of sealing can improve the Rigidity and strength of automotive front end cross sill, solder joint failure and panel beating cracking phenomena in intensive test, have effectively been avoided, and and then improve the Rigidity and strength of end frame structure before body in white, thereby durability and the service life of improving car load.
In addition, above the automotive front end cross sill 201 that provides in embodiment there is high rigidity and high-intensity while, because the structure of its hollow also makes the weight of himself lighter.Therefore realized the object that improves automotive front end cross sill Rigidity and strength in the situation that not gaining in weight.
In embodiment, the closed ring cross-sectional plane of automotive front end cross sill 201 can be formed by steel plate bending above, also can by forge or the technique such as casting one-body molded.The automotive front end cross sill 201 being bent to form is easily made, but can see seam on its cross-sectional plane.Integrated automotive front end cross sill 201 be can't see seam on its cross-sectional plane, and its whole Rigidity and strength is higher, and bending resistance and anti-twisting property are stronger.
Preferably, the form of above-mentioned automotive front end cross sill 201 can be jointless Guan Liang.That is, automotive front end cross sill 201 is the structure of pipe beam type.The steel of the pipe beam type using can directly be provided by steel mill, without depot, by mould moulding again, have therefore reduced production cost expense.
Further, the form of above-mentioned automotive front end cross sill 201 can be rectangular tube beam, and the structure of rectangular tube beam has smooth carrying surface, is conducive to install and arrange other parts thereon.
Again as shown in Figure 2, in embodiment more of the present utility model, one end of above-mentioned cross sill beam body can be designed to front end left column installation end (being the lower end shown in Fig. 2), another opposite end is designed to front end right column installation end (being the upper end shown in Fig. 2), and described front end left column installation end and described front end right column installation end upwards bend perk symmetrically with respect to the middle part of described cross sill beam body.This structure that upwards bends perk can improve the load-carrying properties at cross sill beam body two ends effectively, makes this two opposite end have the less trend that is bent downwardly distortion after stressed.
And described front end left column installation end has the structure coordinating with front end left column 202, described front end right column installation end has the structure coordinating with front end right column 203.Here related fit structure can be the structures such as tapped bore, riveted holes, weld nugget, so that coordinate with front end left column 202 and front end right column 203.
Again as shown in Figure 2, in other embodiment of the present utility model, on the described cross sill beam body of described front end left column installation end inner side, be provided with front-end module left installation bracket 205, on the described cross sill beam body of described front end right column installation end inner side, be provided with front-end module right mounting bracket 206.Front-end module left installation bracket 205 and front-end module right mounting bracket 206 are for carrying the front-end module being installed on automotive front end cross sill 201, as the front end ornamental trimming of automobile---front bumper, front grid etc.
Again as shown in Figure 3, front-end module left installation bracket 205 and front-end module right mounting bracket 206 are stuck on cross sill beam body with the form being coated, this coated form can form by welding, and while installing with the form being coated, need on automotive front end cross sill 201, not punch, therefore there will not be the Rigidity and strength causing due to punching to reduce problem yet.
In summary, the pipe beam type automotive front end cross sill 201 that the utility model is set forth can reach following useful technique effect in automobile design:
(1) improved the Rigidity and strength of body structure;
(2) there is the simple enclosed construction of pipe beam type;
(3) realized the low and lightweight object of cost;
(4) improved the durability of car load.
In addition, as shown in Figure 4, embodiment of the present utility model also provides a kind of body structure framed structure, comprise the automotive front end cross sill 201 as described in above-mentioned arbitrary embodiment, one end of automotive front end cross sill 201 is provided with front end left column 202, another opposite end is provided with front end right column 203, front end left column 202 is connected with left front girder assembly 205, and front end right column is connected with front right longitudinal beam assembly 206.
In Fig. 4, automotive front end cross sill 201 forms front end assembly with front end left column 202, front end right column 203, front-end module left installation bracket 204,205 welding of front-end module right mounting bracket, then this front end assembly and left front girder assembly 206, front right longitudinal beam assembly 207 have been connected to form body structure framed structure, the assembling function of body structure can not only be realized well, the Rigidity and strength of body structure can also be guaranteed well.
The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of 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.
