Abstract
The utility model discloses a kind of automobile front protecting supporting construction being conducive to leg protection under pedestrian; comprise supporting construction body; described supporting construction body comprises stay bearing plate; stay bearing plate top is provided with the mounting hole I be connected with water tank upper beam, and stay bearing plate side is provided with the mounting hole II be connected with front guarantor's crossbeam adapter plate.Without the need to changing the original layout of automotive front end; supporting construction is protected before setting up; leg knee position under pedestrian can be supported when colliding; make ligamentum patellae protected; reduce the lower upper and lower angle of bend of leg, and the energy of lower impact on legs can be absorbed, before the lower leg of buffering directly bumps against rigidity, protect the distance of crossbeam; reduce impact acceleration, alleviate injury.
Description
Technical field
The utility model relates to automobile technical field, especially relates to a kind of automobile front protecting supporting construction being conducive to leg protection under pedestrian.
Background technology
In automotive safety research field, pedestrian protecting safety is very important component part, and pedestrian protecting design and vehicle front moulding, layout, structure are relevant.
Pedestrian is the disadvantaged group in traffic, and pedestrian lower leg is again one of the most vulnerable position.According to investigations, pedestrian injury reaches in the actual bodily harm region simplifying injury criteria more than 2 grades, and the injury ratio of lower limb is 34%, and the lower extremity injury of 44.2% is caused by the collision of automobile front beam.When there is lower limb collision, the axial moment of torsion of impact force and possible leg combines, and injury can be caused to be multiplied, along with the acceleration of the collision before car and pedestrian's lower limb subsequently, pedestrian lower leg is subject to shearing force and bending force, thus causes the injuries such as the fragmentation of long bone fracture, knee cap and ligament injury.
Utility model content
Not enough for prior art, technical problem to be solved in the utility model is to provide a kind of automobile front protecting supporting construction being conducive to leg protection under pedestrian.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of automobile front protecting supporting construction being conducive to leg protection under pedestrian; comprise supporting construction body; described supporting construction body comprises stay bearing plate, and stay bearing plate top is provided with the mounting hole I be connected with water tank upper beam, and stay bearing plate side is provided with the mounting hole II be connected with front guarantor's crossbeam adapter plate.
Further, described stay bearing plate is provided with reinforcing rib structure.
Protect above crossbeam before described supporting construction body is positioned at.
Described stay bearing plate is be provided with protruding bending plate structure.
Described reinforcing rib structure is cavity structure.
The utility model compared with prior art, has the following advantages:
Without the need to changing the original layout of automotive front end; supporting construction is protected before setting up; leg knee position under pedestrian can be supported when colliding; make ligamentum patellae protected; reduce the lower upper and lower angle of bend of leg, and the energy of lower impact on legs can be absorbed, before the lower leg of buffering directly bumps against rigidity, protect the distance of crossbeam; reduce impact acceleration, alleviate injury.
Accompanying drawing explanation
Below the content expressed by each width accompanying drawing of this specification sheets and the mark in figure are briefly described:
Fig. 1 is the utility model supporting construction schematic diagram.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the utility model supporting construction scheme of installation.
Fig. 4 is the left view of Fig. 3.
Fig. 5 is the utility model impact simulation schematic diagram.
In figure: 1. supporting construction body, 101. mounting hole I, 102. mounting hole II, 103. stay bearing plates, 2. water tank upper beam, 3. before protect crossbeam adapter plate, 4. before protect crossbeam, 5. go up leg, 6. knee, 7. descend leg.
Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, detailed description of the invention of the present utility model is described in further detail.
As shown in Figures 1 to 5; this is conducive to the automobile front protecting supporting construction of leg protection under pedestrian; comprise supporting construction body 1; under the prerequisite not affecting vehicle layout; protect before supporting construction body 1 is positioned at before being arranged in above crossbeam 4 and protect, under pedestrian leg and collision happens process in play a protective role.
Supporting construction body comprises stay bearing plate 103, and stay bearing plate 103 is for being provided with protruding bending plate structure, and be provided with reinforcing rib structure on the supporting plate, reinforcing rib structure is cavity structure, and namely stay bearing plate is the covering being located at reinforcing rib structure.
Stay bearing plate top is provided with the mounting hole I 101 be connected with water tank upper beam 2, and stay bearing plate side is provided with the mounting hole II 102 be connected with front guarantor's crossbeam adapter plate 3.Namely the top of supporting construction body is connected on water tank upper beam by mounting hole I, and the side of supporting construction body is connected on front guarantor's crossbeam adapter plate by mounting hole II, and stay bearing plate is arranged by vehicle front, and reinforcing rib structure is positioned at stay bearing plate rear.
In the process of colliding, two mounting holes mainly play a part to fix this supporting construction; When stay bearing plate 103 Main Function is above leg 7 and collision happens under pedestrian, covering is played the effect of a part of buffering energy-absorbing by compression; Simultaneously, shank crossbeam deforms, by dynamic changes process, reduce velocity of impact, move to certain phase gaskin crossbeam to be upspring in the bottom of leg under pedestrian, reduce moment of flexure degree, but after the bottom of lower leg upsprings, under pedestrian, will move and then contact with grid in the top of leg backward with upper leg 5.
Now the front end panel of this supporting construction plays buffer action, the top of lower leg is stoped to be moved backward further, thus lower leg ligamentum cruciatum elongation and upper tibia moment of flexure can be controlled by actv., meanwhile, this supporting construction can also absorb the energy of lower lower leg crash, protects the distance of crossbeam before increasing lower leg direct impact rigidity, thus reduction impact acceleration, damp impacts absorbs energy, protection knee 6 ligament, reaches the object of leg under protection pedestrian; Reinforcing rib structure below mainly under stay bearing plate stops the top of leg play when moving further and support this structure and do not move backward, the effect of assisting stay bearing plate to play energy-absorbing to alleviate.
By reference to the accompanying drawings the utility model is exemplarily described above; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that design of the present utility model and technical scheme are carried out; or design of the present utility model and technical scheme directly applied to other occasion, all within protection domain of the present utility model without to improve.
