The present invention relates to the fixing of the shield which is installed in front of the engine room of the vehicle for the safety of the occupant in the event of a collision of the vehicle, and in particular, the fixed support point of the shield to the upper and lower two support points when the pedestrian is shocked, And a shield fixing device for a vehicle for protecting a pedestrian to prevent a person from getting into a big injury.

According to the US Department of Transportation, 71 percent of pedestrian injuries and 85 percent of deaths occur in frontal collisions when cars and pedestrians collide. When a person hits a car in front of the car, the leg under the knee is broken in 0.03 seconds, and after 0.23 seconds, the whole body, especially the legs, enter the underside of the body, or the head hits the bonnet and windshield.

It was also suggested that the front bumper be made of a larger and more resilient material to prevent pedestrian injuries, or the angle of the bumper should be lowered to allow the upper and lower bodies to move together.

Children, in particular, are more likely to bump into the bumper and get into the car, unlike adults. In addition, the safety of pedestrians is also banned from the double emblems of folding emblems and leisure vehicles, which are also introduced in domestic large vehicles, mainly in Europe.

Every year, 1.2 million people die in car accidents worldwide and 10 million are injured. More than a third of these are pedestrians. Nevertheless, safety issues have been concentrated only on occupants in car design. Experts estimate that the design of pedestrian safety could save about 700,000 people, 20% of pedestrians injured or injured per year.

Considering the safety of pedestrians in a car crash is also directly linked to car sales.

In 1998, the European Commission on Enhancement of Vehicle Safety (EEVC) issued a report on detailed inspection provisions, evaluation criteria, and safety design measures to evaluate the safety of pedestrians in the event of a car crash. European automakers signed a voluntary agreement and the vehicles introduced after 2010 will comply with the pedestrian safety requirements of the EEVC. In other words, in order to export cars to Europe in the future, it is necessary to design a car considering pedestrian safety.

Pedestrian safety has already become the standard for consumers to buy new cars. The European New Vehicle Assessment Program (Euro-NCAP), established in 1997 by the five European governments and the European Community (EC), has five stars representing the safety of pedestrians and five stars representing the safety of passengers in front and side vehicle crashes. We add and announce dog.

Pedestrian safety is evaluated by calculating the amount of impact on the legs, upper body, and the head of adults and children, based on when a car and a pedestrian collide at 40 km / h. As described above, various researches for the safety of pedestrians are in progress.

For such pedestrian safety, as shown in Figure 1, a shield member made of synthetic resin material having ribs installed at regular intervals on the upper part of the base fixed by the fastening member over the entire length of the radiator fixing horizontal member 200 installed in front of the chassis. If the pedestrian's leg collides with the bumper while the support stiffness is shown without deformation as 100, it prevents the pedestrian's leg from invading below the vehicle, thereby inducing a small bending of the knee.

By the way, the radiator fixing horizontal member is usually a member that does not have a high rigidity and is simply bolted between the shield 100 and the radiator fixing horizontal member 200 unsuitably for supporting the shield 100 as a whole. It has a structural form.

Therefore, when the pedestrian's legs collide with each other, the shield 100 has a problem in which the pedestrian's leg is invaded downward under the vehicle as the shield 10 is lifted as shown in FIGS. 2A and 2B.

Therefore, in view of the above problems, the present invention maintains the coupling rigidity between the shield and the radiator fixing lateral member, and has a double upper and lower coupling structure, and further increases the rigidity due to the pipe member, so that the bridge is stiff when the pedestrian is hit. The purpose is to provide a technique for preventing the intrusion of the lower part of the.

The object is to have a shield formed with ribs on the upper surface of the base as a synthetic resin material, and the bent portion is fixed to the radiator fixing horizontal member at both ends between the shield back and the radiator fixing horizontal member fixed by the fastening member. This is achieved by having a double bond structure which is fixed to the shield as a pipe member.

Fixing means for the pipe member and the shield;

As a first embodiment, at least two or more vertical coupling pieces which are interviewed and fixed to the rib of the shield are achieved by welding to the pipe member.

In the second embodiment, it is achieved by forming a cutout at a predetermined position on each rib back surface, and horizontally joining pieces fitted to the cutout to be welded to the pipe member.

And the third embodiment is achieved by a pipe member which forms a semicircular groove at a predetermined position on each rib back surface, and is seated in the groove.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings of preferred embodiments.

3 is an exploded perspective view of the present invention, and FIGS. 4A, 4B and 4C are perspective views of the first to third embodiments in which the pipe member and the shield of the present invention are coupled.

Radiator fixing horizontal member 20 is fixed to the shield back and the fastening member; And a bent portion 31 fixed at both sides of the radiator fixing horizontal member 20 between the shield 10 and the radiator fixing horizontal member 20 to be coupled to the shield 10 as a fixing means. The pipe member 30 is characterized by having a coupling structure of which is fixed to the shield.

Fixing means for the pipe member 30 and the shield 10;

As a first embodiment, at least two or more vertical coupling pieces 32 welded to the pipe member 30 are interviewed and fixed to the rib 12 of the shield 10 as in FIG. 4A.

In the second embodiment, as shown in FIG. 4B, a cutout portion 12A is formed at a predetermined position on the rear surface of each rib 12, and a horizontal coupling piece 33 fitted to the cutout portion 12A is connected to the pipe member 30. It is characterized in that welded to.

And the third embodiment is characterized in that the semi-circular groove (12B) is formed in a predetermined position on the back of each rib 12, as shown in Figure 4c, characterized in that consisting of a pipe member 30 is seated coupled to the groove (12B) .

According to the present invention configured as described above, the bent portion 31 at both ends of the pipe member 30 is fixed by welding or bolting between both ends of the radiator fixing horizontal member 20.

At this time, the pipe member 30 is preferably in a straight state. Of course, even if it has a gentle curve structure will not be out of the technical scope of the present invention, of course, in this case, the design dimension of each coupling piece (32, 33) or the design of the cutout (12A) and semi-circular groove (12B) Adequate dimensional variations must be preceded.

Meanwhile, in the related art, the shield 10 and the radiator fixing horizontal member 20 are fixed only to the fastening member S without the pipe member 30, and a bending moment is generated as a support point when colliding with the pedestrian's leg. Lifting up) caused the pedestrian's legs to break into the lower part of the body, but in the present invention, since the upper and lower support points are fixed via the pipe member 30 through the pipe member 30, the force due to the collision moment force is not generated. Achieves the action of increasing the bond stiffness.

In addition, the stiffness of the pipe member 30 itself also has the effect of increasing the effect of two stones.

In the present invention, when the pedestrian collides with the bumper, not only the bending rigidity of the pipe member but also the rigidity of the pipe member fixing means combine to support the intrusion of the pedestrian's legs under the bumper.

The technology according to the present invention described above is for illustrative purposes only, it will be understood by those skilled in the art that various modifications and applications may be carried out based on the present specification. It is intended that the present invention fall within the true spirit and scope of the present invention and the appended claims.
