CONSTITUTION:As for an automobile bumper structure which supports a bumper reinforcing member 14 consisting of a front panel 12 and a rear panel 13 by a bumper stay 15, a hole is formed in the rear panel 13, and the front edge part of the bumper stay 15 is welded on the front panel 12 through the hole.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile bumper structure.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 10, there is a vehicle bumper structure in which a bumper reinforcing member 2 of a bumper 1 is supported by a bump paste 3.

In such a bumper structure, when a shock is applied from the front, the bumper stay attaching portion 2a of the bumper reinforcing member 2 may be buckled and deformed as shown by the chain double-dashed line in FIG.

Therefore, conventionally, a bumper structure as shown in FIG. 11 has been proposed.

In the bumper structure shown in FIG. 11, a deformation preventing member 4 having a substantially U-shaped cross section is provided inside the bumper reinforcing member 2 to increase the strength of the bumper reinforcing member 2.

[0006]

However, in the above-described conventional automobile bumper structure, the number of parts is increased by the deformation preventing member 4, so that the vehicle body weight is increased and
There was a problem that the manufacturing cost increased.

The present invention has been made in view of the above circumstances, without increasing the vehicle body weight and the manufacturing cost,
An object of the present invention is to provide a bumper structure for an automobile capable of increasing the strength of a bumper reinforcing member.

[0008]

According to the present invention, in order to achieve the above object, in a bumper structure of a vehicle in which a bumper reinforcing member including a front panel and a rear panel is supported by a bumper stay, a hole is formed in the rear panel and the hole is formed. The front end of the bumper stay is welded to the front panel.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of a bumper structure for an automobile according to the present invention will be described in detail below with reference to the accompanying drawings.

1 to 7 show an embodiment of the present invention. Front bumper 11 of automobile 10 of the present embodiment
In the above structure, the bumper reinforcing member 14 including the front panel 12 and the rear panel 13 is supported by the bumper stay 15.

In this embodiment, a hole 16 is formed in the rear panel 13, and the front end portion 15a of the bump paste 15 is welded to the front panel 12 through the hole.

The front end portion 15a of the bumper stay 15 is formed by bending it so as to open in the upward and leftward and rightward directions, in particular, like a flange.

The rear panel 1 of the bumper reinforcing member 14
3, a flange portion 13a is also provided upright around the hole 16, and the flange portion is welded to the central portion of the bump paste 15.

The rear panel 1 of the bumper reinforcing member 14
The flange portion 13a of No. 3 does not necessarily have to be provided, and may be provided as appropriate in consideration of the strength of the bumper reinforcing member 14.

In the structure of such an embodiment, the bumper 11
When the vehicle receives an impact from the front, the impact force is received not only by the bumper reinforcing member 14 but also directly by the bump paste 15, and is dispersed.

Therefore, in the above-described embodiment, the deformation preventing member which is a separate component is not particularly required, and the number of components is not increased. Therefore, the strength of the bumper reinforcing member 14 can be increased without increasing the weight of the vehicle body and the manufacturing cost. Can be increased.

In FIGS. 8 and 9, a bumper stay 15 having a substantially U-shaped cross section that opens downward is welded with a reinforcing member 17 that closes the lower opening, so that the cross section has a box shape.
This shows an example in which the strength of the front portion of the bumper stay 15 is increased.

In FIGS. 1 to 4, 18 is a shock absorbing material and 19 is a bumper skin member.

In the above embodiment, the present invention is applied to the front bumper, but the present invention is not limited to this and may be applied to the rear bumper of an automobile.

[0020]

As described above, according to the automobile bumper structure of the present invention, in the automobile bumper structure in which the bumper reinforcing member including the front panel and the rear panel is supported by the bump paste, a hole is formed in the rear panel, Since the front end of the bumper stay is welded to the front panel through the hole, the impact force received from the front can be dispersed not only to the bumper reinforcing member but also directly to the vehicle body through the bumper stay.

Therefore, in the present invention, since the deformation preventing member which is a separate component is not required, the number of components does not increase,
Therefore, the strength of the bumper reinforcing member can be increased without increasing the vehicle body weight and the manufacturing cost.
