Description

Pedestrian shank protective device and automobile

Technical field

The utility model belongs to body of motor vehicle accessories technical field, and in particular to a kind of pedestrian shank protective device and vapour Vehicle.

Background technique

It is more often degree of protection of the consideration vehicle to occupant when previous Automobile Design, and has ignored weak to pedestrian etc. The protection of gesture group.With the development of the automobile industry, it is increasingly taken seriously to the protection of the disadvantaged group such as pedestrian.China exists 2009 have just issued the proposed standard of pedestrian protecting regulation GBT-24550-2009, while Chinese new car assessment routine C-NCAP is true Started to enforce due to 2018.Shank protection is exactly a ring more important in pedestrian protecting, and automobile front bumper Rigidity, position and size have important influence to pedestrian shank damage.

As shown in Figure 1, the collision area of existing front bumper and shank is broadly divided into three parts, respectively central collision region 1, a side impact region left side 2 and the side impact region right side 3.Wherein: central collision region 1 because of the reason of there are bumper grille and modelling features, this Part is enough to the support strength of shank；A side impact region left side 2 and the side impact region right side 3 are this area Liang Chu at the big plane of bumper Domain is on the weak side to the support of shank during side impact.As shown in Fig. 2, during side impact, after pedestrian shank contacts front bumper Deformation is contacted with preceding collision beam together, and shank deflection is the spacing size of front bumper and preceding collision beam.I.e. due to side The support for touching the right 3 pairs of shanks in a region left side 2 and side impact region is on the weak side, and pedestrian shank is unable to get effective support in collision process, So that shank excessively causes ligament tension to be even broken to car bending.

Therefore, it is necessary to develop a kind of new pedestrian shank protective device and automobile.

Utility model content

The purpose of the utility model is to provide a kind of pedestrian shank protective device and automobiles, can increase front bumper in side impact In the process to the support of pedestrian shank, to reduce during side impact to the injury of pedestrian lower leg.

Pedestrian shank protective device described in the utility model, including front bumper and preceding collision beam are insured before described The left part and right part of thick stick are equipped with the support construction to extend back, and the front end of the support construction and the inner wall of front bumper are fixed The front end face of connection, the rear end of support construction and preceding collision beam, which contradicts, to be cooperated.

Further, the support construction and front bumper integrated injection molding.

Further, the support construction includes the pillar seat being fixed on front bumper inner wall, and fixed setting The front end face of pillar on pillar seat, the rear end of the pillar and preceding collision beam, which contradicts, to be cooperated.

Further, the pillar seat uses DOGHOUSE structure.

Automobile described in the utility model, including such as pedestrian shank protective device described in the utility model.

The utility model have the advantage that by support construction be arranged in front bumper left part (i.e. side impact region left) and Right part (side impact region is right), and support construction arrives between front bumper and preceding collision beam in pedestrian shank side collision When front bumper, the support construction and preceding collision beam form a supporter, front bumper side that can be poor to rigidity Region provides support, excessive so as to avoid the inside intrusion of shank front-bumper, reduces the bending degree of shank, thus Reach the injury reduced to leg.In addition, also having many advantages, such as structure simple, supporting & stablizing and practical.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the prior art；

Fig. 2 is the schematic diagram that the prior art is contacted with pedestrian shank side；

Fig. 3 is the schematic diagram that the utility model is contacted with row shank side；

Fig. 4 is the schematic diagram of support construction in the utility model；

In figure, before 1- central collision region, a 2- side impact region left side, the 3- side impact region right side, 4- pedestrian shank, 5- front bumper, 6- Collision beam, 7- support construction, 7a- pillar, 7b- pillar seat.

Specific embodiment

The utility model is described in further detail with reference to the accompanying drawing.

Pedestrian shank protective device as shown in Figure 3, including front bumper 5 and preceding collision beam 6, the front bumper 5 Left part (i.e. side impact region left) in Fig. 1 and right part (i.e. the side impact region right side in Fig. 1) be equipped with the support construction to extend back 7, the front end of the support construction 7 is fixedly connected with the inner wall of front bumper 5, the rear end of support construction 7 and preceding collision beam 6 Front end face contradicts cooperation.Since front bumper 5, support construction 7 and preceding collision beam 6 together form a support system, increase Add front bumper 5 in the intensity in side impact region, when side collision occurs, can effectively support pedestrian shank 4, reduce leg Portion caused by overbending because injuring.

In the present embodiment, the left part and right part of the front bumper 5 are respectively arranged a support construction 7, and support construction 7 with Front bumper 5 is integrated injection molding.

As shown in figure 4, the support construction 7 includes pillar the seat 7b, Yi Jigu being fixed on 5 inner wall of front bumper Pillar 7a on pillar seat 7b is set calmly.When front bumper 5 and preceding collision beam 6 are mounted on automobile, the pillar 7a Rear end and preceding collision beam 6 front end face contradict cooperate.In the present embodiment, the pillar seat 7b uses DOGHOUSE structure, Using the advantages of DOGHOUSE structure be can effectively pre- sink-mark prevention, it can be ensured that the appearance looks elegant of front bumper 5.It is described convex Column 7a uses BOSS rod structure, the advantage is that under the premise of ensuring secure support, dosage is less, meets automotive light weight technology Requirement and cost is relatively low.The length of support construction 7 can be adjusted by DOGHOUSE structure and the length of BOSS rod structure, branch The length of support structure 7 is depending at a distance from front bumper 5 with preceding collision beam 6.

The present embodiment additionally provides a kind of automobile simultaneously, including such as pedestrian shank protective device described in the utility model.
