Embodiment Construction
[0025] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0026] Such as image 3 and Figure 4 As shown, a car front wall structure according to a preferred embodiment of the present invention includes a front wall panel 1, a beam assembly 2 and a water deflector 3. The beam assembly 2 is formed by butting an upper beam 21 and a lower beam 22. The coaming panel 1 has an integrated structure, the upper end of the dash panel 1 is lapped to the lower edge of the beam assembly 2 and welded to the lower edge of the beam assembly 2, the lower edge of the beam assembly 2 is the lower edge of the lower beam 22, The water deflector 3 is located below the crossbeam assembly 2 and is welded with the outer surface of the dash panel 1. The...

The invention relates to the field of automobiles and discloses an automobile front wall structure. The automobile front wall structure comprises a front wall panel, a cross beam assembly and a water guide plate; the front wall panel is of an integrated structure; the upper end of the front wall panel is in lap-joint with the lower edge of the cross beam assembly and welded together with the lower edge of the cross beam assembly; and the water guide plate is positioned under the cross beam assembly and welded together with the external side surface of the front wall panel. According to the automobile front wall structure, the upper end of the front wall panel is welded together with the cross beam assembly after being in lap-joint with the cross beam assembly; therefore, compared with the existing automobile front wall structure in which the front wall panel is welded together with a cross beam through a front wall reinforcing plate, the automobile front wall structure has the advantages that one row of welding spots are omitted and the welding cost is reduced; welding edges between the front wall panel and the cross beam assembly are easy to glue; as the front wall panel is of an integrated structure and the water guide plate is welded on the external side surface of the front wall panel, the water in the water guide plate cannot be leaked to the internal side of the front wall panel; and the welding edges of the water guide plate and the front wall panel do not need to be additionally glued so that the gluing procedure can be omitted and the water inlet risk is greatly reduced.
Description
technical field [0001] The invention relates to the field of automobiles, in particular to an automobile front wall structure. Background technique [0002] The front wall assembly is located between the passenger compartment and the engine compartment, both of which have an urgent need for space. At the same time, the OEM needs to reduce the length, width and height of the vehicle in consideration of cost and shape. In this case, the front wall assembly also needs to meet the basic functions of sound insulation, heat insulation, force transmission and driver protection, and the space requirement cannot be infinitely compressed. [0003] Currently on the market, the structure of the cowl assembly is basically composed of a cowl panel and a cowl frame. The front wall panel is divided into integral type and split type, and the front wall frame is divided into built-in type, external type and internal and external mixed type. [0004] Such as figure 1 and figure 2 As shown...
