Embodiment

Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.

The utility model provides a kind of end new wind structure, as shown in Figures 1 to 4, new wind structure 1 comprises four blocks of side plates 10, every block side plate 10 forms multi-ladder formula structure after repeatedly bending, the dual-side of each side plate 10 is welded and fixed the integral type ladder structure forming new wind structure 1 between two, form enlarging 9, first bending 8 at car body blast inlet 4 place of new wind structure 1 by the first bending 8 to be fixed together by laser welding with end wall of car body 2.

As shown in Figure 2, new wind structure 1 comprises 4 blocks of stainless steel side plates 10, every block side plate 10 forms multi-ladder formula structure through repeatedly bending, in the utility model, every block side plate 10 is through five bendings, forming the structure with multi-ladder as shown in Figure 3, wherein the first bending 8 is in multi-ladder, with end wall of car body 2 laser welding. The side of 4 blocks of side plates 10 is welded and fixed between two, forms the structure of a hollow, i.e. new wind structure 1 so that new wind structure 1 is integral type ladder structure. Two end faces of 4 blocks of side plates, fixing end face 11 and permanent seat 12 is formed respectively after bending, fixing end face is positioned at car body air inlet, outward extending direction, the first bending 8 is consistent with the wrap direction of fixing end face 11, outside bending, enlarging 9 is formed in car body blast inlet 14 position, enlarging 9 when not increasing new wind structure overall volume, do not change air channel structure in car, can increase incoming air area, and then increases air output.

As shown in Figure 1 to Figure 3, car body blast inlet 4 place is provided with the fixing end face 11 of outside bending, and fixing end face 11 is as the extension part of car body blast inlet 14, and one side is fixed with car body, another side and grid 13 overlap fixing, and note glue and realize sealing so that grid 13 covers car body blast inlet 4, and grid 13 is provided with filtration unit, the impurity such as the sandstone in the new wind of introducing can be filtered, avoid entering in air channel, avoid noise on the one hand, on the other hand for passenger inside the vehicle provides clean fresh air. Permanent seat 12 is provided with multiple screw 6, by bolt 7, new wind structure 1 is achieved a fixed connection with air channel 3 in car, and note glue sealing, the new wind introduced is avoided to shunt other positions entering in car body, other parts in car body are produced unnecessary injury, also avoid new distinguished and admirable mistake simultaneously, reduce air output. Also screw 6 can be set on fixing end face 11, after grid 13 and fixing end face bolt are connect, note glue sealing.

The length of the first bending 8 is between 30 50mm, and optimum length is 40mm, and namely new wind structure 1 is 40mm with the contact surface length that is welded and fixed of end wall of car body 2. What the first bending 8 and end wall of car body 2 adopted laser welding is connected and fixed mode, to meet stainless steel processing for the requirement of appearance effect, new wind structure 1 entirety is fixed and supporting role simultaneously, can significantly improve the integrally-built strength and stiffness in end.

As shown in Figure 3 and Figure 4, permanent seat 12 is positioned at car blast inlet 5 place, is bolted to connection with air channel in car 3. Permanent seat 12 can be overall with side plate 10 one-tenth one, one-body molded, is a bending part of one block of side plate 10, it is possible to as shown in Figure 4, and permanent seat 12 is fixed by welding and side plate 10, and welding place polishes process. At each bending part of side plate 10, all lead circle process, the round and smooth transition of each bending part so that new wind through new wind structure 1 into the car air channel 3 time, do not produce noise. In the utility model, four blocks of side plates 10 carry out welding operation in side edge again after bending, can reduce welding capacity, thus the distortion amount that the new wind structure 1 that welding is formed produces is little, and appearance effect is good.

In production application, according to design requirements, four blocks of side plates 10 are formed new wind structure 1 according to welding after setting size bending, behind new wind structure 1 and end wall of car body 2 fixed position, laser welding is utilized to fix, again according to easy for installation, it is fixedly connected with air channel in car 3 and grid 13 respectively, completes the fixed installation of new wind structure 1.

As mentioned above, it is necessary, the scheme content given by combining, it is possible to derive and similar technical scheme. In every case being the content not departing from technical solutions of the utility model, any simple modification, equivalent variations and the modification above embodiment done according to technical spirit of the present utility model, all still belongs in the scope of technical solutions of the utility model.
