Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bumper structure for improving the rigidity of a bumper body provided at the front of a vehicle body of an automobile.

[0002]

2. Description of the Related Art As shown in FIG. 5, a front hood 100 is arranged on the upper side and a bumper body 101 is arranged on the lower side of the front surface of the body of an automobile. On the left and right of the front of the vehicle body, the upper side is the front hood 100, the inner side and the lower side are the bumper body 101, and the outer side is the front fender 1.
The left and right headlamps 103 are arranged so as to be sandwiched between the two. Bumper body 101 and headlamp 1
As shown in FIG.
3 The flange portion 101a is formed on the peripheral edge of the bumper body 101 so as to overlap the step portion 103a provided around the vehicle width direction.
Is provided so that the inside cannot be seen through the gap 104 with the headlamp 103, and the rigidity of the bumper body 101 is secured.

A gap 104 between the bumper body 101 and the headlamp 103 is provided to some extent in consideration of the assembling of the bumper body 101 and the headlamp 103. There is a problem that it will not look good.

[0004]

SUMMARY OF THE INVENTION The bumper body 10 described above.
The first flange portion 101a is preferably long in order to ensure rigidity, and if it is longer than necessary, the head lamp 103 is damaged by the tip of the flange portion 101a when the bumper body 101 is displaced in the vehicle front-rear direction. There is a risk.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above problems and provide a bumper structure capable of improving the appearance and rigidity.

[0006]

In order to solve the above-mentioned problems, the present invention forms cutouts on both upper sides of the bumper body, which are adjacent to the lower ends of the left and right lamps, respectively.
A flange portion provided toward the inside of the vehicle body is formed at the edge portion of the cutout portion, and a rib that gradually becomes thinner toward the inside of the vehicle body is provided at the tip of the flange portion. Further, according to the present invention, the rib is provided so as to continuously project from a flange portion of the lamp peripheral portion of the bumper body adjacent to at least a corner portion from the inside of the vehicle body to the lower end portion of the lamp. Further, the shape of the rib is gradually formed from the root of the rib toward the tip of the rib. Furthermore, the rib is integrally formed with the bumper body.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail below with reference to the drawings. 1 to 4 show an embodiment of a bumper structure according to the present invention.

1 to 4, a vehicle body 1 of an automobile
In the front part, as shown in FIG. 1, a front hood 2 is provided on the upper side, a front bumper 3 is provided on the lower side of the front hood 2, rear sides of the front bumper 3 are provided with front fenders 4 on both sides of the front hood 2, respectively. It is arranged. Left and right headlamps 5 are arranged so as to be sandwiched between the front ends of the front hood 2 and the front fender 4 and the left and right upper ends of the front bumper 3.

As shown in FIG. 2, in the headlamp 5, the headlamp unit 51 has a substantially triangular outer appearance, and a flange portion 51 having a step portion 52 formed on the periphery thereof.
a is provided. In the headlamp unit 51,
A plurality of mounting stays 53 are provided, and the mounting stays 53 are assembled to the vehicle body 1 via screws 54. The front hood 2, the front fender 4, and the front bumper 3 are assembled so as to overlap the flange portion 51a of the headlamp 5. The front bumper 3 is provided with a grille opening 31 in the center of the front surface of the bumper body 30 in the vehicle width direction for cooling a radiator and the like in the engine room. Notches 32 for assembling the headlamp 5 are provided on the left and right of the upper side of the bumper body 30, and an extension 33 adjacent to the front end of the front hood 2 is provided between the notches 32. ing. A flange portion 30a is provided around the bumper body 30, and a portion of the flange portion 30a where the cutout portion 32 is provided, particularly a portion adjacent to the inner corner portion 51b of the headlamp 5, is shown in FIG. Further, as shown in FIG. 4, a rib 30b whose tip gradually becomes thinner toward the flange portion 51a of the headlamp 5 is provided by integral molding. The rib 30b is formed to have a length that faces the stepped portion 52 of the headlamp 5 and approaches immediately before.

The front bumper 3 is provided with a flange portion 33b having a screw hole 33a at the upper end of the extending portion 33,
A stay 34 having a screw hole 34a is provided in the flange portion 30a inside the rear end of both sides of the bumper body 30, and a stay 35 having a screw hole 35a is provided in the flange portion on the lower rear surface of the bumper body 30. These screw holes 3
3a, screw hole 34a, and screw hole 35a through the screws 36, 37, 38, respectively, to the vehicle body 1 side bumper body 3
0 is assembled.

According to the above construction, the headlamp 5 is attached to the front end of the vehicle as an assembling procedure. next,
Assemble the front bumper 3 to the front end of the vehicle. At this time, if the front bumper 3 is pushed rearward of the vehicle body, the rib 30b provided on the bumper body 30 of the front bumper 3 comes into contact with the stepped portion 51 of the headlamp 5 and is not pushed further. Since the rib 30b of the front bumper 3 is formed thin toward the tip, even if the front bumper 3 is strongly pushed backward by an impact from the front, the rib 30b hits the headlamp 5 and bends. There is no risk of damaging or damaging 5.

As described above, according to the above-described embodiment, the inner corner portion 51b of the headlamp 5, particularly the inner corner portion 51b of the flange portion 30a of the bumper body 30 where the cutout portion 32 is provided.
The flange portion 51 of the headlamp 5 is adjacent to
Since the rib 30b whose tip is gradually thinned toward "a" is provided, the rigidity can be improved. Also,
When the bumper body 30 moves to the rear of the vehicle body due to an impact from the front, the rib 30b bends and deforms when it hits the headlamp 5 with a slight movement, so there is no risk of damaging or damaging the headlamp 5.

The present invention is not limited to the above-described embodiments. For example, although the front bumper has been described in the above embodiments, the present invention can be applied between the rear bumper and the tail lamp. it can. Further, it goes without saying that the range of the ribs 30b and the lengths of the ribs can be arbitrarily set in relation to the lamp, and other modifications can be made as appropriate without departing from the scope of the invention. .

[0014]

As described above, according to the bumper structure of the present invention, the following effects can be obtained.
2. The bumper body according to claim 1, wherein notches are formed on both sides of an upper portion of the bumper body so as to be adjacent to respective lower ends from inside of the left and right lamps, and flanges are provided at edges of the notches toward the inside of the vehicle body. However, since a rib that gradually becomes thinner toward the inside of the vehicle body is provided at the tip of the flange portion, the rigidity of the bumper in the peripheral portion of the headlamp can be improved. The rib according to claim 2, wherein the rib is continuously projected from the flange portion of the lamp peripheral portion of the bumper body adjacent to at least a corner portion from the vehicle body inner side to the lower end portion of the lamp, so that the appearance can be improved and the bumper can be improved. The rigidity of the shape change part can be improved. In claim 3, since the shape of the rib is gradually thinned from the rib root toward the rib tip, the lamp is not damaged by contact with the bumper. In claim 4, since the rib is integrally formed with the bumper body, the effect can be obtained without increasing the number of parts.
