The present invention relates to a bumper that 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, in particular, when the pedestrian installed inside the bumper is impacted by a bridge enters the lower part of the vehicle, The present invention relates to a guard bar fixing device installed to prevent wear.

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 then get under 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 focused on occupants only when designing cars. Experts estimate that the design of pedestrian safety could save about 700,000 people, 20% of pedestrians injured or injured a year.

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

In 1998, the European Commission on Automotive Safety (EEVC) published a report on detailed inspection provisions, evaluation criteria, and safety design measures to assess 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, pedestrian safety is essential.

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 this pedestrian safety, as shown in Figure 1, the guard bar 100, which is fixed at both ends of the radiator fixing horizontal member 200 installed at the front of the chassis, is fixedly installed to surround the front inside of the front shield. The guard bar 100 shows rigidity without deformation, and when the pedestrian's leg collides with the bumper, the guard bar 100 fixed to the left and right of the lower part of the body prevents the pedestrian's leg from intruding below the vehicle. It acts as an induction to make the bending small.

In order to prevent the intrusion of the pedestrian bridge, the rigidity of the guard bar 100 should be maintained sufficiently.

However, when the pedestrian's legs collide with the support bar that is far from the guard bar 100, that is, the radiator fixing transverse member 200, and the bumper is separated at a relatively large distance to withstand the load due to the rigidity of the guard bar itself, the guard bar 100 As a result of the deformation of the pedestrian's leg, the intrusion is increased.

This problem is exacerbated when the vehicle is medium to large.

In order to prevent this, the thickness of the cross section of the guard bar 100 is increased as a means of increasing the rigidity of the pipe.

Therefore, in view of the above problems, the present invention provides a technique for preventing the bridge from invading the lower part of the vehicle body when the pedestrian collides by increasing the support strength without increasing the rigidity of the guard bar, that is, the weight due to the increase in the cross-sectional area. There is a purpose.

This object is achieved by securing a support between a guard bar made of a pipe of a gentle arc structure and a transverse member for fixing a radiator.

The support is preferably achieved by forming a bent portion to cover the installation phase difference between the guard bar and the radiator fixing transverse member.

And this support is preferably achieved by forming a bent flange on both sides in the longitudinal direction and a rib groove in the center.

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

FIG. 2 is a plan perspective view of the present invention, FIG. 3 is a front perspective view of the present invention, and FIG. 4 is a cross-sectional view of main parts of the present invention.

Gentle arc-shaped guard bar 10;

Radiator fixing horizontal member 20; And a support 30 which is fixed between the guard bar 10 and the radiator fixing horizontal member 20.

The support 30 is preferably characterized in that the guard bar 10 and the radiator fixing horizontal member 20 is formed to bend portion 31 to cover the phase difference respectively installed in the vehicle.

And this support 30 is fixed to the center of the largest separation interval between the guard bar 10 and the radiator fixing horizontal member 20 is the largest.

And it is characterized by having a rib groove 33 is formed in the groove from the top to the bottom in the center in the longitudinal direction having a flange 32 to the upper side in both sides to meet the purpose of light weight and strength increase.

The present invention configured as described above is fixed by welding or bolt connection between the guard bar 10 and the radiator fixing horizontal member 20. In the present invention, the stiffness of the support bar as well as the bending stiffness of the guard bar when the pedestrian collides with the bumper middle portion serves to support the intrusion of the pedestrian's legs under the bumper. On the other hand, the support 30 has an upward bending flange 32 to both sides and has a rib groove 33 in the center in the longitudinal direction from the top to the bottom to meet the purpose of light weight and increase the strength of the unit Furthermore, by inducing a reduction in the cross-sectional area of the guard bar 10, the weight of the overall vehicle can be reduced.

The support according to the present invention described above is for illustrative purposes only, and it will be understood by those skilled in the art that various modifications and applications may be made 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.

The present invention constructed and acted as described above has the effect of preventing the bridge from invading the lower part of the vehicle body in the event of a pedestrian collision by increasing the support strength without increasing the rigidity of the guard bar, i. It can lead to a reduction in the weight of the vehicle has the effect that can be.
