Reinforcement structure of automobile bumper face
The present invention relates to a reinforcement structure of an automobile bumper face, and more particularly, to a reinforcement structure of an automobile bumper face that forms a horizontal rib and a vertical rib that reinforces impact resistance inside the bumper face to reduce and reduce weight of a separate part. It is about.
In general, a bumper face (BF) of a vehicle is a component that forms an exterior of a bumper B (Bumper) installed to protect a vehicle body before and after the vehicle, as illustrated in FIG. 1.
Such a bumper face (BF) is a cross-sectional view of the conventional bumper (B) in the cross-section AA line of Figure 1 as shown in Figure 4 the energy absorber foam (20; Energy Absorber Foam) and the reinforcement member (30; ) Is combined to form a wrapper to form a bumper (B).
Therefore, the external shock is transmitted to the energy absorber foam 20 and the reinforcing member 30 through the bumper face (BF) to perform the function of shock absorption.
However, the conventional structure as described above has a problem that the weight increases due to the use of a separate component such as a reinforcing member and the cost increases as the number of work is increased, there is a problem in the weight and economy of the vehicle.
Accordingly, the present invention has been made in view of the above-described problems, and an object of the present invention is to provide a reinforcement structure of an automobile bumper face that can provide sufficient impact resistance while reducing the use of separate parts and reducing weight and cost. There is.
1 is an exemplary view of a vehicle showing an application part of the present invention;
Figure 2 is an exemplary view showing the configuration of the present invention for the cross section along line A-A of Figure 1,
3 is an enlarged view of part C of FIG. 2;
4 is a diagram illustrating a conventional configuration of a cross section taken along the line A-A of FIG.
(Explanation of symbols for the main parts of the drawing)
B; Bumper BF; Bumper Face
11; Horizontal ribs 11a; Hollow part
12; Vertical rib
In order to achieve the above object, the present invention provides a bumper face (BF) structure forming the exterior of a bumper (B) of a vehicle,
An automobile characterized in that it is formed by forming a plurality of horizontal ribs (11) formed at right angles to the inside of the bumper face (BF) and vertical ribs (12) connecting the ends of the horizontal ribs (11) to each other. Provides a reinforcement structure for the bumper face.
Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
Figure 2 is an exemplary view showing the configuration of the present invention for the cross-section line AA of Figure 1, as shown in the present invention to form a plurality of horizontal ribs 11 formed horizontally perpendicular to the inside of the bumper face (BF) The ends of the horizontal ribs 11 are formed by forming vertical ribs 12 connected to each other.
At this time, the connecting portion of the horizontal rib 11 which is integrally molded and connected to the inner surface of the bumper face (BF) is preferably provided with a hollow portion (11a) as shown in FIG. , Which is formed by injecting gas during molding and forming a thin connection portion to prevent a sink mark from occurring on the bumper face.
The bumper face (BF) formed as described above has sufficient impact resistance against external impact due to the horizontal ribs 11 and the vertical ribs 12 without using a separate reinforcing member.
The present invention configured as described above can reduce the weight while maintaining the impact resistance of the bumper to bring the effect of contributing to the weight reduction of the vehicle, it is possible to achieve cost savings by not using a separate component. In addition, labor savings can be achieved, thereby improving productivity.
