The present invention relates to a shock absorber for automobiles, and more particularly, by coupling an extension bracket extending rearward to both sides in a round bar-shaped curved portion to a lower frame of a carrier, structurally reducing weight to improve vehicle fuel economy and parts Improve productivity by reducing cost and assembly labor, and by strengthening rigidity by forming impact absorbing protectors made of steel, not only can it prevent internal parts from damage in front of the vehicle, but also improve the safety of pedestrians and drivers. The present invention relates to a shock absorber for automobiles.

The front end module (FEM) of the vehicle is to frame the vehicle in one step by modularizing the devices constituting the front of the vehicle.

In general, the front end module of the vehicle includes a carrier coupled to both side frames of the vehicle and forming a front portion of the vehicle, and a radiator, a condenser, and a fan mounted on the carrier. Cooling devices such as fans) and peripheral devices. In other words, a cooling module such as a condenser and a writer is fixed to the front of the carrier, and a bumper cover for protecting the vehicle body and the occupant against shock from the outside is mounted in front of the vehicle body.

On the other hand, the vehicle body structure is gradually increasing its rigidity in order to ensure the safety of the driver and passengers in the interior of the vehicle during front and side collision. As described above, the stiffness of the vehicle body gradually being enhanced means that the degree of damage to the pedestrian is increased as the stiffness of the vehicle body increases when the pedestrian collides with the vehicle being driven.

In recent years, European legislation has been enacted to promote the safety of pedestrians when a vehicle collides with a pedestrian. That is, in addition to the existing crash test (mainly for driver protection), the test for pedestrian protection (when the pedestrian and vehicle collide, the knee joint of the pedestrian leg is bent at the bumper side, so that the head of the hood By legalizing tests to prevent accidents in the form of price, the protection of pedestrians as well as the driver is being strengthened.

Accordingly, in order to prevent the pedestrian from colliding with the vehicle, the lower end of the leg is not bent or an excessive impact amount has been proposed, in which a shock absorbing protector is installed at the lower position of the carrier.

Carrier 110 forming the front portion of the front end module, as shown in Figure 1, the front frame 111a and the lower frame 111b and the front and rear left and right vertical support (112a, 112b) Frame 113, the head lamp support frame (114) extending to the left and right of the upper frame (111a), the headlamp support frame 114 and the left and right vertical support (112a) The vehicle body coupling part 115 coupled to 112b and a center support 116 integrally formed at the front center portion of the carrier 110 are included.

Conventional automobile shock absorber protector 140 is coupled to the lower frame 111b of the carrier 110, as shown in Figure 2, as a plate-like plastic member having an elastic force toward both front to the center toward the front. It is formed to be wider to be wider, and a plurality of through-holes 142 are formed at regular intervals so as to absorb the external impact energy when colliding with the pedestrian. In addition, the coupling member 143 having an approximately 'b' shape is provided on one side to which the shock absorbing protector 140 is coupled. The shock absorbing protector 140 is fixed by a plurality of bolts on the front and lower ends of the lower frame 111b through fastening holes 144 formed at predetermined positions on the upper, lower, left and right sides of the coupling member 143. Combined.

However, the conventional shock absorbing protector 140 is located opposite the bottom of the bumper cover (not shown), so that the load is easily transmitted and damaged along with the deformation of the bumper cover during the front collision, and its shape is forward. Since the cover is formed to extend, there is a problem such as a decrease in fuel economy and a cost increase due to the increase in weight. Accordingly, there is a problem in that the vehicle is directly impacted by a weak external shock, and a crack is generated in the carrier and a cooling part mounted on the inside of the carrier, thereby causing damage to the vehicle internal parts.

In addition, since the material of the shock absorbing protector 140 is made of plastic, the rigidity is insufficient, and in order to mount it on the lower frame 111b of the carrier 110, a plurality of fixing means such as bolts are required, and the like. There was a problem that productivity is reduced due to an increase in cost and assembly labor.

The present invention has been made to solve the above problems, by combining a pair of extension brackets extending rearward from the round bar-shaped curved portion to the lower frame of the carrier, structurally reduced weight to improve vehicle fuel economy and parts cost And to reduce productivity of assembly and improve productivity.

Another object of the present invention is to form a shock-absorbing protector made of steel to enhance rigidity, thereby preventing damage to components during frontal collision of the vehicle, and promoting pedestrian safety.

According to the impact shock protector for automobiles of the present invention devised to achieve the object as described above, the shock absorber for automobiles coupled to the lower frame of the carrier constituting the front end module (FEM). In the (Protector), the shock absorbing protector, the curved portion is formed in the form of a round bar convexly curved toward the center with respect to the front of the lower frame; It characterized in that it comprises a pair of extension brackets of which one end is connected to both sides of the curved portion and extends rearward, and a vertical fixing part fixed to the lower frame as the other end of the horizontal extension.

In addition, the vertical fixing portion, a rectangular body having a predetermined size is formed perpendicular to the horizontal extension portion is characterized in that coupled to the bolt through at least one or more fastening holes corresponding to the lower frame.

In addition, the shock absorber is preferably formed of a steel (Steel) material.

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

Carrier 10 is coupled to the protector according to the present invention, as shown in Figure 3, the front frame consisting of the upper frame (11a) and lower frame (11b) and the left and right vertical support (12a, 12b) on the front 13, the head lamp support frame 14 extending to the left and right sides of the upper frame 11a, the head lamp support frame 14 and the left and right vertical supports 12a and 12b. ) And a center support (16) formed integrally with the front center portion of the carrier 10 and coupled to the vehicle body coupling portion 15, the same as in the prior art, the following detailed description of the configuration It will be omitted.

The shock absorber 40 for a vehicle according to the present invention includes a curved portion 20 and a pair of extension brackets 30.

The curved portion 20 is formed in a round bar shape and is formed convexly curved toward the center with respect to the front of the lower frame (11b).

A pair of extension brackets 30 are provided at predetermined positions on both sides of the rear surface of the curved portion 20. The pair of extension brackets 30 are formed in a plate shape, one end of which is connected to both sides of the rear surface of the curved portion 20 and extends rearward, and the other end of the horizontal extension portion 31. As the lower frame (11b) is made up of a vertical fixing part 33 is fixed.

In addition, the vertical fixing part 33 is formed in a vertical shape having a predetermined size as a quadrangular body and is coupled to the bolt through at least one fastening hole 34 corresponding to the lower frame 11b.

The shock absorbing protector 40 having the structure as described above, as compared with the prior art can be greatly reduced the assembly labor by the fixing means such as bolts.

Table 1 shows the results of the front collision test of the shock absorber 40 for automobiles according to the present invention.

(Based on the test result of the conventional shock absorber as 100.0%.)

Table 1 shows the test results of the conventional shock absorber as a test result of the present invention as 100%, while the weight of the protector 40 is reduced to 40.0% while the acceleration, shear strain and bending angle are minimized. I can see.
