Abstract
The utility model discloses a pedestrian crus protection device, which comprises a bumper lower protection plate body, wherein two side reinforcing ribs (11) and middle reinforcing ribs (12) are added on the lower protection plate body, and simultaneously, the installation height and the installation angle of a lower protection plate are reasonably regulated. The pedestrian crus protection device is additionally provided with the crossed reinforcing ribs on the original bumper lower protection plate, the crossed reinforcing ribs have the main effect of reinforcing the support effect on the crus, on one hand, the crus is prevented from being brought to a position under an automobile, the crus bending angle is reduced, on the other hand, the rigidity is reasonably matched with energy absorption foam, and a part of energy is properly absorbed, so the safety of pedestrians is better protected. Simultaneously, the more reasonable installation height and the more reasonable installation angle are designed, and the crus is preferably prevented from being brought to the position under the automobile during the collision.
Description
Technical field
The utility model belongs to pedestrian's passive security field.Relate to a kind of automobile pedestrian shank fender guard, relate in particular to the pedestrian protection of automobile front beam special use.
Background technology
Since European Union took the lead in formulating 2003/102/EC pedestrian protecting rules in 2003, countries in the world were organized in succession the pedestrian protecting rules are studied.Wherein the GTR standard will be implemented in various countries as global rules future; China is one of its member state; " GB/T 24550-2009 automobile is to pedestrian's crash protection " with reference to the GTR standard issued, the vehicle of listing also will satisfy the pedestrian protecting laws and regulations requirement at home when the time comes.Simultaneously, ENCAP is also improving the proportion of pedestrian protecting in star rating year by year.
In automobile and pedestrian's the collision case, the injured probability of shank is very high, therefore, injury values to shank in the GTR standard has been made regulation, requirement is in the Collision test of following leg pattern piece and vehicle front 40Km/h, the maximum dynamic bending angle of knee is not more than 19 °, and the maximum dynamic shearing displacement of knee is not more than 6.0mm, and shank upper end acceleration/accel is not more than 170g.In order to satisfy above technical requirements, must a kind of later-model bumper/spoiler lower support structure of design, during with abundant reduction vehicle and pedestrian impact to the injury of pedestrian's shank.
Summary of the invention
The utility model designed a kind of pedestrian's shank fender guard, and it has solved when reducing vehicle and pedestrian impact the problem to the injury of pedestrian's shank.
In order to solve the technical matters of above-mentioned existence, the utility model has adopted following scheme:
A kind of pedestrian's shank fender guard comprises panel reality under the bumper/spoiler, it is characterized in that: increased both sides reinforced rib and middle reinforced rib on the panel reality down described.
Further, the thickness of described both sides reinforced rib is greater than the thickness of reinforced rib in the middle of described.
Further, the thickness of described both sides reinforced rib is 4.5mm-5.5mm; The thickness of reinforced rib is 1.5mm-2.5mm in the middle of described.
Further, described both sides reinforced rib and middle reinforced rib are cruciform construction.
Further, the material of described both sides reinforced rib and middle reinforced rib is the composite material of PP and EPDM.
Further, be inclined upwardly when described time panel reality is installed, making itself and vehicle ground plane angle is 6 °.
This pedestrian's shank fender guard has following beneficial effect:
(1) the utility model pedestrian shank fender guard; under original bumper/spoiler, added the criss-cross reinforced rib above the backplate; it mainly acts on is to strengthen the shank supporting role; prevent that shank is rolled under the car on the one hand; reduce the shank angle of bend; with energy-absorbing foam rational Match rigidity, suitably absorb part energy on the other hand, thus better protection pedestrains safety.
(2) the utility model pedestrian shank fender guard has designed more rational setting height(from bottom) and setting angle, and shank is involved at the bottom of car in the time of can better preventing to collide.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in Figure 1, a kind of pedestrian's shank fender guard comprises panel reality under the bumper/spoiler, is increasing both sides reinforced rib 11 and middle reinforced rib 12 on the panel reality down.The thickness of both sides reinforced rib 11 is greater than the thickness of middle reinforced rib 12.The thickness of both sides reinforced rib 11 is 4.5mm-5.5mm; The thickness of middle reinforced rib 12 is 1.5mm-2.5mm.Both sides reinforced rib 11 and middle reinforced rib 12 are cruciform construction.The material of both sides reinforced rib 11 and middle reinforced rib 12 is the composite material of PP and EPDM.
As shown in Figure 2, preceding guarantor's connecting bore 23 of following backplate front end is connected with the bumper/spoiler bottom by screw, and mudwing connecting bore 22 is connected with mudwing by screw, and the subframe connecting bore at following backplate rear portion is connected by the anterior water tank cross sill of double buckle and subframe.
Following backplate 1 setting height(from bottom) mainly is meant down backplate 1 foremost and preceding guarantor's energy-absorbing foam 32 joint place terrain clearances, and setting height(from bottom) designs less than 280mm.As shown in Figure 3, in the shank Collision test, the liftoff 262mm of following centroid position of shank test module 31, the liftoff bottom 25mm of test requirements document shank, when shank contacted with following backplate 1, the liftoff 287mm of shank barycenter was if backplate 1 terrain clearance is greater than the shank height of center of mass down, shank just has the trend of rolling up at the bottom of the past car during collision, and the shank angle of bend will increase.When mounted simultaneously, be inclined upwardly when described time backplate 1 is installed, making itself and vehicle ground plane angle theta is 6 °.Shank was involved under the car when setting height(from bottom) can better prevent to collide, better protection pedestrian's shank.The utility model pedestrian shank fender guard adopts the PP+EPDM material, and simple in structure, and machine-shaping is easy.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obvious realization of the present utility model is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technical scheme to carry out; or design of the present utility model and technical scheme are directly applied to other occasion without improving, all in protection domain of the present utility model.
