Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a bumper structure for an automobile.

[Prior Art] The bumper side of a car is designed to improve the appearance and strength by covering the bumper skin on the bracket side. However, in order to avoid damage such as deformation of the vehicle body especially in the event of a light collision. In order to achieve this, various structures have been devised for the structures of the bracket side and the bumper skin (see, for example, Japanese Patent Laid-Open No. 57-209442).

[Problems to be Solved by the Invention] As to the bracket side and bumper skin of the conventional example, as shown in the above publication, the bracket side is fixed to the vehicle body, and further the bumper skin is fixed to the bracket side. Many. If a sliding portion is not properly provided in the mounting-related portion, it is not possible to cope with heat contraction after mounting and it is not possible to mitigate the input at the time of a light collision.

In particular, in the case where the bumper side divided portion that comes into contact with the vehicle body has an L-shaped step, a proper arrangement of the fixed portion and the sliding portion has been a problem.

[Means for Solving the Problems] The present invention provides a vehicle bumper structure that solves the above problems.

That is, the split part on the upper part of the bumper side that contacts the vehicle body,
In an L-shaped step formed by a vertical division and a horizontal division in the vehicle front-rear direction, an L-shaped bracket side including a vertical section and a horizontal section is formed along the vertical division and the horizontal division. The vertical portion is fixed to the vehicle body together with the bumper skin, and the end portion of the lateral portion is attached to the vehicle body along with the bumper skin so as to be slidable in the front-rear direction thereof. The fixed portion of the bumper skin is arranged above and below the sliding portion of the bumper skin in the vehicle front-rear direction with respect to the lateral portion.

[Operation] A bracket side consisting of a vertical portion and a horizontal portion is provided along the divided portion of the vehicle body and bumper side with an L-shaped step, and the vertical portion is fixed to the vehicle body together with the bumper skin, and the tip of the horizontal portion is fixed. It is attached to the body together with the bumper skin so that it can slide in the front-back direction. Further, a fixing portion for the vehicle body is formed in the lateral portion in the longitudinal direction, and a sliding portion of the bumper skin for the lateral portion is further formed.

Therefore, it is possible to reduce variations in the bumper attachment, improve the accuracy of the split portion, and ease the input at the time of a light collision.

[Embodiment] The details of the present invention will be described below with reference to an embodiment shown in the drawings.

The split portion between the vehicle body 2 and the bumper side 4 is formed with an L-shaped step between the vertical split portion 6 and the horizontal split portion 7, and the bracket side 10 on the bumper side 4 side has a vertical portion 12 along the vertical split portion 6. The lateral portion 13 along the lateral dividing portion 7 is formed in an L shape.

The bracket side 10 is attached to the vehicle body 2, and the upper and side surfaces of the bracket side 10 are covered with the bumper skin 16, which are attached to each other at the following portions.

F mounting part: Bumper skin 16 on vertical part 12 of bracket side 10
At the same time, it is fixed to the vehicle body 2 with stepped bolts 18. The mounting surface of the vertical portion 12 is the mounting reference surface of each member (and the reference surface for heat shrinkage).
With respect to the vehicle body 2, the bracket side 10, the bumper skin 16, the vehicle body vertical direction (C direction), the vehicle body longitudinal direction (D
Direction) and the left-right direction of the vehicle body (E direction).

G mounting portion: The tip end of the lateral portion 13 of the bracket side 10 is mounted on the vehicle body 2 so as to be slidable in the vehicle body front-rear direction (D direction) together with the bumper skin 16 with bolts, nuts, and sliding long holes. As a result, the bracket side 1
0, the mounting position of the bumper skin 16 in the vehicle body vertical direction (C direction) and the vehicle body lateral direction (E direction) is restricted.

H mounting part: in the longitudinal direction on the lateral part 13 of the bracket side 10,
The bolts 20 and the nuts 21 are used to provide several (two in FIG. 2) fixing portions for the vehicle body 2. This makes the car body 2
On the other hand, the mounting position of the bracket side 10 is restricted in each direction.

J mounting part: Several sliding parts (six upper and lower parts in FIG. 2) of the bumper skin 16 with respect to the lateral part 13 are provided above and below the lateral part 13 of the bracket side 10. That is, a pin 25 is projected on the inner surface of the bumper skin 16, and is inserted into a long hole in the vehicle body front-rear direction (D direction) provided on the bracket side 10 and clipped 27
To prevent pin 25 from falling out. As a result, the bumper skin 16 is allowed to slide only in the vehicle front-rear direction (D direction), and the mounting position is restricted in the vehicle body vertical direction (C direction) and the vehicle body lateral direction (E direction).

A flange 30 is extended horizontally on the top surface of the lateral portion 13 of the bracket side 10, and a bumper skin 16 is formed on the top surface of the flange 30.
The top 32 of the is fitted. And the horizontal part 13
Since the mounting is restricted by the F mounting portion and the G mounting portion, the gap K between the top portion 32 of the lateral division portion 7 and the vehicle body 2 is maintained substantially constant in the vehicle body front-rear direction (D direction).

[Advantage of the Invention] The present invention is configured as described above, and the mounting positions of the vehicle body, the bracket side, and the bumper skin in the laterally divided portion are orderly, and the gap K is kept constant, so that there is variation in mounting. The number of parts is extremely small, the accuracy of the split parts is improved, and the bumper and the vehicle body are integrated into one body.

Further, since the fixed portion and the sliding portion of the bumper side are configured as described above, it is possible to cope with heat contraction, and particularly the input (for example, P) at the time of a light collision is shared by the bumper side, so the input is relaxed. , It will be the reinforcement of the car body again.

Since the bumper skin can be easily reinforced, the thickness of the skin can be set thin.
