The present invention relates to a front underride preventing member of a vehicle, and more particularly, by installing the front bumper rail to a certain height to prevent the under bumping of the front bumper when colliding with a sports utility vehicle or the like to prevent damage of the front undercar of the vehicle. It relates to a ride preventing member.

1 is a view showing a bumper difference between a conventional front bumper rail and another vehicle, and FIG. 2 is a view showing an example of generating an underride of FIG. 1.

Referring to the drawings, the front bumper rail 2 is installed at an end portion in front of the bumper side rail 4. The front bumper rail 2 of the passenger car has a height difference H from another bumper 6 such as a sports utility.

The bumper side rails 4 are provided with front bumper rails 2 on the same front line.

Accordingly, the front bumper rail 2 is underrided in an accident of a passenger vehicle in which the front bumper rail 2 having a height lower than that of the bumper 6 of the sport utility vehicle is installed.

Accordingly, the passenger vehicle has a problem in that the degree of damage, including the engine, is greatly generated because bumpers of other vehicles enter and collide with the engine side.

The object of the present invention has been proposed to solve the problems of the prior art made as described above is to increase the front bumper rail to a certain height to prevent the under-ride of the front bumper when colliding with a sports utility vehicle or the like to reduce the amount of damage To provide a front underride prevention member.

Other objects and advantages of the invention will be described below and will be appreciated by the embodiments of the invention. Furthermore, the objects and advantages of the present invention can be realized by means and combinations indicated in the claims.

In order to achieve these technical challenges,

A front side rail;

It is further provided to be inclined at the front end of the front side rail front end to provide a front under-ride member of the vehicle, characterized in that consisting of the under-ride member to be installed so that the front bumper rail is raised.

The underride member is composed of a reinforcing member installed to protrude on the upper end of the front side rail, and a bumper rail coupling plate attached by welding to install the front bumper rail on the front of the reinforcing member.

The reinforcing member includes a cover part in which the space part is formed to be inclined, a mounting plate formed on the left, right side, and the rear side of the cover part and having a fastening hole formed at the left, right side and the rear side to be fastened to the front side rail, and the cover. It consists of an attachment support plate that is bent around the front space of the part and is formed to weld the bumper rail coupling plate.

The bumper rail coupling plate has fastening holes formed at each corner, and is formed of bent portions formed to be stepped up and down horizontally.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. Prior to this, terms or words used in the specification and claims should not be construed as having a conventional or dictionary meaning, and the inventors should properly explain the concept of terms in order to best explain their own invention. Based on the principle that can be defined, it should be interpreted as meaning and concept corresponding to the technical idea of the present invention.

Therefore, the embodiments described in the specification and the drawings shown in the drawings are only the most preferred embodiment of the present invention and do not represent all of the technical idea of the present invention, various modifications that can be replaced at the time of the present application It should be understood that there may be equivalents and variations.

3 is a view showing a front underride preventing member of the vehicle according to an embodiment of the present invention, Figure 4 is a view showing the installation of the front underride preventing member of the vehicle in FIG.

Referring to the drawings, the front underride preventing member 20 of the vehicle includes a front side rail 22; The front side rail 22 is further inclined at the upper end of the front end so that the front bumper rail 24 is installed to be high.

The underride member 20 is attached by welding to install a front bumper rail 24 and a reinforcement member 30 installed to protrude from the upper end of the front side rail 22 and the front side of the reinforcement member 30. Bumper rail coupling plate 40 is composed of.

The reinforcing member 30 has a cover portion 32 in which the space portion 31 is formed to be inclined, and extends on the left, right and rear sides of the cover portion 32 so as to be fastened to the front side rail 22. Mounting plate 34 formed with a fastening hole 33 is formed on the right side and the rear side, and the attachment is formed to be bent around the front space 31 of the cover portion 32, the bumper rail coupling plate 40 is welded It consists of a support plate 35.

The bumper rail coupling plate 40 has fastening holes 41 formed at each corner, and is composed of bent portions 42 formed to be horizontally up and down stepped.

Referring to the operation of the present invention made as described above, it is composed of the combination of the anti-ride member 20, the reinforcing member 30 and the bumper rail coupling plate 40. The reinforcing member 30 is mounted by mounting plates 34 formed at the edge of the cover portion 32 and fastened by bolts through the fastening hole 33.

Then, the bumper rail coupling plate 40 welded to the attachment support plate 35 of the cover part 32 having the space part 31 is welded to complete the installation of the underride prevention member 20.

When the underride prevention member 20 is installed on the front side rail 22, the front bumper rail 24 is installed to be evenly supported.

Accordingly, the height of the front bumper rail 24 is increased to narrow the height difference H1 from the sport utility vehicle, which is another vehicle. Therefore, even when the vehicle collides at a low speed, the front bumper rail 24 is prevented from underriding, thereby reducing the amount of damage.

As mentioned above, although this invention was demonstrated by the limited embodiment and drawing, this invention is not limited by this and is given by the person of ordinary skill in the art to the following, Of course, various modifications and variations are possible within the scope of equivalents of the claims to be described.

As described above, the present invention has the effect that the front bumper rail is prevented from underride by reducing the height difference during a low-speed collision with a sports utility vehicle having a relatively high ground clearance, thereby minimizing damage and reducing repair costs.
