The specific embodiment
Below in conjunction with accompanying drawing, further illustrate the specific embodiment of the present utility model.
As shown in Figure 2, Figure 5 and Figure 6, in automobile, passage assembly 1 comprises middle channel body 11 and at least one reinforcement 12, and reinforcement 12 is welded in middle channel body 11, and and middle channel body 11 between form a closed cavity 13.Reinforcement 12 has increased depth of section and the area of middle passage assembly 1, has improved the intensity of middle passage assembly 1, and closed cavity 13, in frontal crash of vehicles, has good directional tagging to impact load simultaneously, improves the safety performance of automobile.Because reinforcement 12 has improved the bulk strength of passage assembly 1 in automobile, the sheet metal thickness of middle channel body 11 also can reduce accordingly.For example, the sheet metal thickness of channel body 11 in the automobile in existing design can be reduced to 0.7mm-0.8mm from 1.0mm-1.4mm, thereby alleviate the weight of middle channel body 11.Although passage assembly 1 increases the weight that is welded on the reinforcement 12 in middle channel body 11 in automobile of the present utility model, but in automobile, the overall weight of passage assembly 1 approximately reduces 20%-30% than middle passage weight of the prior art, thereby reaches the object that alleviates passage assembly 1 weight in automobile.According to the actual needs of body drawing, 2 reinforcements 12 of stack mutually can be set in middle channel body 11, form two closed cavities, the intensity of passage assembly 1 in further improving.Certainly in the situation that meeting automotive parts manufacture and assembling, also can adopt a plurality of reinforcements 12 mutually to superpose and be arranged in middle channel body 11.
In the present embodiment, as shown in Fig. 2-Fig. 4, middle channel body 11 comprises middle channel body front end 111, middle channel body middle part 116, middle entire body body seat installation portion 113, middle channel body end 114, middle channel body extreme end 115 from front to back successively, reinforcement 12 arises from the position corresponding with middle channel body front end 111, terminates in the position corresponding with middle channel body chair mounted portion 113.Middle channel body extreme end 115 are middle channel body ends 114 by vehicle body fore-and-aft direction from front to back to tail end.Reinforcement 12 adopts punching press one-body molded, and processing technology is simple.As shown in Fig. 8-Figure 11, wherein Figure 10 has concealed front coaming plate 2, so that more intuitively express the structure of weld.Front coaming plate 2 is mainly used for the partition of machinery space and passenger accommodation, stops that the waste gas of machinery space enters in crew module; When vehicle body front cross rail 3 is mainly used in vehicle body collision, load is born and is transmitted, and therefore the load of front cross rail 3 need to be transmitted smoothly and is absorbed, and could improve the passive security coefficient of automobile.On middle channel body front end 111, weld reinforcement 12, then welding edge is welded and fixed with the corresponding vehicle body front cross rail 3 being blocked by front coaming plate 2, the mode that is welded and fixed like this can make body forward structure load directly through front cross rail 3, be delivered to smoothly middle channel body 11 and reinforcement 12 and 13 places of the closed cavity between them of middle passage assembly 1, thereby rationally transmit impact load and absorb corresponding energy, reaching the object that improves automotive safety coefficient.
In the present embodiment, as shown in Figure 5 and Figure 6, in automobile, the cross-sectional plane of the reinforcement 12 of passage assembly 1 is " M " type, should " M " type be approximate " M " type." M " type comprises at the horizontal shoulder of both sides and the horizontal recess between two horizontal shoulders." M " type is axially symmetric structure, at its bending part, chamfering is set, and two horizontal shoulders of its both sides are short horizontal surface structure, under two horizontal shoulders are oblique toward middle part, is transitioned into the horizontal recess in middle part, and this horizontal recess is long horizontal surface structure.Adopt approximate " M " type structure can make the load of 13 pairs of vehicle front collisions of closed cavity that middle channel body 11 forms there is good directional tagging above.Certainly the cross-sectional plane of reinforcement 12 also can be designed to "Ji" type structure, but the load guidance quality of the closed cavity 13 of this kind of structure formation is less better compared with " M " type structure.
In the present embodiment, reinforcement 12 is provided with perforate, makes like this mechanism being originally installed in middle channel body 11 can be directly installed on reinforcement 12, avoids perforate in middle channel body 11, has guaranteed closure and the anti-corrosive properties of middle channel body 11.
In the present embodiment, as shown in Figure 2, Figure 5 and Figure 6, middle channel body front end 111 to the cross section of middle channel body chair mounted portion 113 is similar "Ji" type.As shown in Figure 2 and Figure 7, when middle channel body end 114 below of middle channel body chair mounted portion 113, transition is approximate " M " type, finally middle channel body extreme end 115 again transition be "Ji" type, such structure can make load transmit smoothly, extreme end 115 transition in middle channel body are " several " character form structure simultaneously, can make it more smooth-going with coordinating of body bottom panel, be convenient to install.
In the present embodiment, reinforced rib 112 is vertically arranged in the both sides of middle channel body 11.According to the length of the middle passage assembly of different automobile types, the reinforced rib 112 of varying number can be set.Operated by rotary motion 1-8 is to reinforced rib 112.Reinforced rib 112 both can add the intensity of persistent erection channel body 11, and in minimizing, channel body 11 is wrinkling, had the effect of leakage while reducing electrophoresis simultaneously.
In the present embodiment, middle channel body 11 adopts laminating welding manner to be welded and fixed with reinforcement 12.As shown in Fig. 2, Fig. 8-Figure 11, the front end position that passage assembly 1 and front coaming plate 2 and front cross rail 3 are welded and fixed in automobile, the welding edge 121 of reinforcement 12 and the laminating of the flange of middle channel body 11 are welded and fixed.As shown in Figure 2 and Figure 6, the part that reinforcement 12 extends to middle channel body chair mounted portion 113 directions, the welding edge 121 of reinforcement 12 is welded and fixed with the sidewall laminating of middle channel body 11.Adopt laminating welding, fitting operation is simple, can effectively guarantee the precision of welding between reinforcement 12 and body 11 simultaneously, has improved the stability of middle passage assembly 1.
Above-described is only principle of the present utility model and preferred embodiment.It should be pointed out that for the person of ordinary skill of the art, on the basis of the utility model principle, can also make some other modification, also should be considered as protection domain of the present utility model.
