Abstract
The purpose of this utility model proposes a kind of engine case being conducive to pedestrian protecting, and this kind of engine case when automobile and pedestrian collision, can reduce the extent of injury to pedestrian head.The engine case being conducive to pedestrian protecting of the present utility model comprises outside plate and inner panel, and key is that described inner panel is provided with some parallel protruding gussets, and the end face of described gusset is provided with coating groove, and described inner panel is connected by the shock insulation glue in coating groove with outside plate.The utility model is by changing the arrangement form of engine case inner panel reinforced rib; make engine case surface rigidity evenly; avoid when colliding; engine case occurs that the excessive pedestrian head generation secondary collision that causes of local stiffness injures; thus make the rigidity in whole head impact region meet head impact requirements; reduce head injury value, reach the object improving pedestrian head protected effect.
Description
Technical field
The utility model relates to a kind of engine case.
Background technology
According to the Relevant Analysis of European Union to road traffic accident, the dead data of pedestrian are 9 times of passenger, and the pedestrian protecting problem of China is also receiving each side's concern day by day." road traffic accident statistics annual report " display of a up-to-date announcement; pedestrian's quantity that China dies from traffic accident in recent years accounts for about 26%; and in Beijing, Guangzhou, the city such as Hangzhou; this numeral is even close to 4 one-tenth; obviously, the pedestrian protecting carrying out vehicle is the key factor reducing mortality in traffic accident.The topmost cause of death of pedestrian comes from the injury of engine case to pedestrian head, therefore, how to reduce the injury of engine case to pedestrian head and become current most important problem.As shown in Figure 1, present engine case inner panel have employed latticed gusset, there will be the excessive phenomenon of local stiffness value at gusset infall, easily causes stress to be concentrated, not easily deforms and make pedestrian head injury values larger during collision.
Summary of the invention
The purpose of this utility model proposes a kind of engine case being conducive to pedestrian protecting, and this kind of engine case when automobile and pedestrian collision, can reduce the extent of injury to pedestrian head.
The engine case being conducive to pedestrian protecting of the present utility model comprises outside plate and inner panel, and key is that described inner panel is provided with some parallel protruding gussets, and the end face of described gusset is provided with coating groove, and described inner panel is connected by the shock insulation glue in coating groove with outside plate.
The above-mentioned protruding gusset be arranged in parallel can make engine case assembly surface rigidity evenly; there will not be the problem that partial points rigidity value is higher; and; shock insulation glue is utilized to connect outside plate and inner panel; be conducive to both and separate body deformability when colliding; make engine case entirety have larger distortion and energy absorption ability, therefore, in pedestrian protecting, be more better than the engine case inner panel that reticular pattern is arranged.
Further, the gusset on described inner panel extends along motor vehicle length direction, and described coating groove has several, and is located on gusset in strip interval.Gusset extends along motor vehicle length direction, the probability that to hit between pedestrian head on gusset can be reduced (unless pedestrian head is just to gusset, otherwise in the evolution of collision, pedestrian head there will be no the chance bumping against gusset, if and gusset extends along vehicle width direction, so in the process of collision development, pedestrian head has the chance bumping against gusset substantially), coating groove extends along gusset direction, can improve the combination degree between gusset and outside plate.
Further, described gusset is provided with several loss of weight through holes, and described loss of weight through hole extends and the both sides of through gusset along the Width of automobile.Loss of weight through hole can alleviate the overall weight of engine hood panel, and suitably reduces the intensity of gusset, and then alleviates the injury to pedestrian head.
Further, the two ends of described gusset are fixedly connected with outside plate, to prevent from thoroughly departing between outside plate and inner panel.
The utility model is by changing the arrangement form of engine case inner panel reinforced rib; make engine case surface rigidity evenly; avoid when colliding; engine case occurs that the excessive pedestrian head generation secondary collision that causes of local stiffness injures; thus make the rigidity in whole head impact region meet head impact requirements; reduce head injury value, reach the object improving pedestrian head protected effect.

Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, the effect and principle of work etc. of detailed description of the invention of the present utility model as the mutual alignment between the shape of involved each component, structure, each several part and annexation, each several part are described in further detail.
Embodiment 1:
As shown in Figure 2,3; the engine case being conducive to pedestrian protecting of the present embodiment comprises outside plate 1 and inner panel 2; described inner panel 2 is provided with some the parallel protruding gussets 3 extended along motor vehicle length direction; the end face of described gusset 3 is interval with the coating groove 4 of several strips, and inner panel 2 is connected by the shock insulation glue 5 in coating groove 4 with outside plate 1.
Gusset 3 is provided with several loss of weight through holes 6, and described loss of weight through hole 6 extends and the both sides of through gusset 3 along the Width of automobile.Loss of weight through hole 6 can alleviate the overall weight of engine hood panel, and suitably reduces the intensity of gusset 3, and then alleviates the injury to pedestrian head.
The above-mentioned protruding gusset 3 be arranged in parallel can make engine case assembly surface rigidity evenly; there will not be the problem that partial points rigidity value is higher; and; shock insulation glue 5 is utilized to connect outside plate 1 and inner panel 2; be conducive to both and separate body deformability when colliding; make engine case entirety have larger distortion and energy absorption ability, therefore, in pedestrian protecting, be more better than traditional engine case.
When pedestrian head and engine case outside plate 1 clash into, engine case outside plate 1 deforms rapidly, and in wavy to external diffusion.Because the intensity of engine case outside plate 1 is too low, the energy-absorbing effect of this portion deforms is very poor, and engine case outside plate 1 moderate finite deformation can occur.Along with the further expansion of distortion, engine case outside plate 1 can drive the engine case inner panel 2 of surrounding to participate in distortion, thus increases energy-absorbing effect.Engine case inner panel 2 in the present embodiment has enough deformation spaces, therefore have stronger energy absorption ability, and endergonic process is long.
