Abstract

The invention relates to a knee protection device of a car belonging to the field of automobile manufacture, wherein the knee protection device of car comprises a square front end bracket; the material of the front end bracket is a metal composite layer structure; the metal composite layer is plastic which is cladded by PA alloy material; the front end bracket is provided with an upper collision bracket and a lower collision bracket; both the upper collision bracket and the lower collision bracket are arched, and two ends are arranged on two sides of the front end bracket. The knee protection device of car of the invention has simple process and low cost, and is more effective for leg and knee protection.

Description

The vehicle knee restraint

Technical field

The present invention relates to a kind of vehicle knee restraint, belong to automobile manufacturing field.

Background technology

When automobile and pedestrian bump; Pedestrian's shank mainly contacts with parts such as automobile front beam, collision prevention girders, light fixture, radiator tank, car bonnets; Because this base part rigidity is all very big, very easily make the shank such as people such as grade of collision, particularly knee joint causes serious harm.

According to pedestrian impact rules Regulation78/2009/EC of European Union and GB/T24550-2009 requirement; All protection has clearly regulation to pedestrian lower leg; At present existing pedestrian protection all is to realize its leg protection with increase energy-absorbing or reinforcing mechanisms on bumper/spoiler or collision prevention girders; This class formation can play the protective effect of a degree to shank, but can't repair damage because of shear displacemant causes knee joint more easily.

Summary of the invention

To the technical matters that exists in the prior art, the object of the present invention is to provide a kind of vehicle knee restraint preferable to people's leg protection performance.

The technical scheme that the present invention adopts is following:

The vehicle knee restraint is characterized in that, comprises the preceding end support that is square, and the material of said preceding end support is the metal composite layer structure, and said metal composite layer is the plastics that are enclosed with the PA alloy material; End support is equipped with collision support and following collision support before said, and the said collision support of going up all is arc with following collision support, the both sides of end support before two ends are installed in.

Further, said upward collision support is injection molded by thermoplastic material with following collision support.

Further, the said collision support of going up is evenly equipped with a plurality of apertures with following collision support.

Further, said aperture is arranged and is cellular, triangle or quadrangle.

Comparatively perfect is that said upward collision support goes to upper and lower on preceding end support with following collision support arranges.

Further, said going up between collision support and the following collision support is provided with front anti-collision beam, the both sides of end support before the two ends of said front anti-collision beam are installed in.

Vehicle knee restraint of the present invention, technology is simple, and cost reduces, and is more effective to shank and knee protective.

Description of drawings

For the ease of it will be appreciated by those skilled in the art that the present invention is further described below in conjunction with accompanying drawing.

Fig. 1 is a structural representation of the present invention.

Fig. 2 is a structural representation of going up the collision support.

Fig. 3 is the structural representation of following collision support.

Fig. 4 is the pedestrian impact scheme drawing.

The specific embodiment

As shown in Figure 1, the vehicle knee restraint comprises the preceding end support 1 that is square, and the material of preceding end support 1 is the metal composite layer structure, and metal composite layer is the plastics that are enclosed with the PA alloy material.

Before end support 1 collision support 2 and following collision support 3 are installed, its two ends are installed in the both sides of preceding end support 1, on collide support 2 and following collision support 3 and on preceding end support 1, go to upper and lower and arrange.

Be provided with front anti-collision beam 4 between last collision support 2 and the following collision support 3, the both sides of end support 1 before the two ends of front anti-collision beam 4 are installed in.

As shown in Figures 2 and 3; Last collision support 2 all is arc with following collision support 3, on collide support 2 and following collision support 3 is injection molded by thermoplastic material, be evenly equipped with a plurality of apertures 9; Aperture 9 is arranged and is structures such as cellular, triangle or quadrangle, helps endergonic structure as long as meet.

As shown in Figure 4; In vehicle and the pedestrian impact process; Last collision support 2 and following collision support 3 respectively with pedestrian's thigh position 6 and shank position about in the of 7 the bilateral while stressed; And collision back collision support destroys consistent with distortion, actv. avoided common protection structure since one-sided upward or collide the injury that can not repair that causes knee joint position 8 formed by shearing force down.

After collision took place, body constructions such as front anti-collision beam 4 and radiator of water tank 5 were made buffering further to human body, further reduced and collided injury.

Above content only is to give an example and explanation to what structure of the present invention was done; Under the technical personnel in present technique field described specific embodiment is made various modifications or replenish or adopt similar mode to substitute; Only otherwise depart from the structure of invention or surmount the defined scope of these claims, all should belong to protection scope of the present invention.
