Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bumper mounting structure, and more particularly to a temporary fixing structure for mounting a bumper on a vehicle body.

[0002]

2. Description of the Related Art Generally, a bumper of an automobile is assembled by first temporarily fixing the bumper to a body panel and then screwing appropriate portions to the body panel. 6 and 7 and FIG. 8 respectively show two examples of such a conventional mounting structure.

In the conventional example shown in FIGS. 6 and 7, a pair of claws 22 projecting rearward are integrally formed on a pair of tongues 21 provided at the left and right center positions of the upper edge of the front bumper 20, and the front body is also formed. A pair of holes 24 respectively corresponding to the pair of claws 22 are formed in the hanging piece portion 23a on the front end side of the panel 23 (upper panel constituting the front portion of the automobile body). In FIGS. 6 and 7, reference numeral 25 is a front hood.

Thus, in this case, when attaching the front bumper 20 to the front body panel 23, the pair of claws 22 of the front bumper 20 are inserted into the holes 24 of the front body panel 23 as shown in FIG. By doing so, the front bumper 20 is temporarily fixed to the front body panel 23, and then the front bumper 20 is bolted to the front body panel 23 or the like with a bolt (not shown).

Further, in the case of the conventional example shown in FIG. 8, a pair of claws 22 of the front bumper 20 are attached to a lower member 27 which constitutes a lower portion of the opening 26 of the front body panel 23, so that the front body panel 23 is attached. The front bumper 20 is temporarily fixed, and then the front bumper 20 is bolted to the front body panel 23 with a bolt (not shown).

[0006]

However, in the conventional bumper mounting structure as shown in FIGS. 6 and 7, the pair of claws 22 are inserted into the pair of holes 24 to temporarily secure the front bumper 20 to the front body panel 23. When inserting, the operator aligns the claw 22 and the hole 24 from the front side of the front bumper 20 while holding the front bumper 20, which makes it difficult to perform the alignment work. That is, since the nail 22 is hidden by the tongue piece 21 for the operator, the front bumper 20 must be moved up, down, left and right little by little to locate the nail 22 and the hole 24 by hand. However, there is a problem in workability. Moreover, in the conventional bumper mounting structure as shown in FIG.
Although the work of inserting the claw 22 into the 6 can be performed relatively easily, there is a problem in that the front bumper 20 cannot be accurately positioned in the left-right direction (the direction perpendicular to the paper surface in FIG. 8).

The present invention has been made in view of the above problems, and an object thereof is to set the bumper to a regular mounting position with respect to the body panel when temporarily fixing the bumper to the body panel. It is an object of the present invention to provide a bumper mounting structure having a structure such that the temporary positioning hooks of the bumper can be surely positioned while being confirmed at the same time, and the temporary fixing hooks of the bumper can be attached to the hook insertion holes of the body panel with good workability. .

[0008]

In order to achieve the above-mentioned object, according to the present invention, a protrusion bent substantially horizontally is provided at the upper end of the bumper, and a hook is provided on the lower surface side of the protrusion. , A recess for accommodating the projecting piece is formed on an upper end surface of a body panel to which the bumper is attached, and a hook insertion hole for engaging the hook is formed in the recessed part, and the projecting piece is fitted in the recess. Then, the hook is engaged with the hook insertion hole to temporarily fix the bumper to the body panel, and under this state, the bumper is attached to the body panel.

Further, in the present invention, under the condition that the projecting piece is inserted into the concave portion and placed on the body panel,
The protrusion and the body panel portion around the protrusion are substantially flush with each other.

[0010]

[Operation] When the protruding piece bent substantially horizontally on the upper end of the bumper is fitted into the recess formed on the upper end surface of the body panel, the operator can visually recognize the protruding piece of the bumper and the recess on the body panel at the same time. However, it is easily performed, and the bumper is assembled in the proper position by the positioning action between the projecting piece and the concave portion, and the hook is easily and quickly engaged with the hook insertion hole.

Further, since the projecting piece and the body panel portion around the projecting piece are substantially flush with each other, when the seal member is disposed between the body panel and the hood, the projecting piece is formed. It is possible to maintain good sealing property without causing unevenness on the sealing surface of the sealing member at one part to deteriorate the sealing property.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to FIGS.
This will be described in detail with reference to FIG.

FIG. 1 shows a four-wheeled vehicle 30 having a bumper mounting structure according to the present invention.
Reference numeral 1 is a front bumper arranged in the front part of the vehicle body, and 2 is a front hood arranged above the front bumper 1.

The above-mentioned front bumper 1 is made of a synthetic resin integrally molded product, and as shown in FIG.
The bumper main body 3 includes a bumper front surface portion 3a and bumper side surface portions 3b and 3c that are bent rearward on both sides of the bumper front surface portion 3a. A grill portion 4 is integrally formed in the upper left and right central portion of the bumper front surface portion 3a.

Further, as clearly shown in FIGS. 2 and 3, the upper end edge of the grill portion 4 is bent at a substantially right angle to the rear portion of the grill portion 4 at different positions along the left-right direction. The horizontal protrusions 5a and 5b are integrally formed. Then, as shown in FIG. 4, hooks 6 that are bent and formed in a hook shape are integrally formed on the lower surfaces of the horizontal protrusions 5a and 5b.

In order to integrally form the hook 6 described above, a slide-type hole 7 for forming an undercut portion is provided in a portion of the grill portion 4 corresponding to the hook 6 (see FIG. 3 and FIG. 4).

On the other hand, as shown in FIGS. 3 to 5, the front body panel 8 to which the upper part of the front bumper 1 is attached (the upper member which is erected in the left-right direction in the front part of the vehicle body) has the front end of its upper surface 8a. A pair of recesses 9 are formed at the side portions and at the locations corresponding to the horizontal protrusions 5a and 5b of the front bumper 1, respectively. As clearly shown in FIGS. 3 and 5, the recess 9 has an open upper portion and a front portion, and is composed of a flat bottom surface 9a and a U-shaped side surface 9b. Also, as shown in FIGS. 4 and 5,
The hook insertion hole 1 is provided at an appropriate position on the bottom surface 9a of the recess 9 described above.
0 is provided.

The depth of the recess 9 of the front body panel 8, that is, the height of the side surface 9b is determined by the front bumper 1
Is set to be approximately equal to the plate thickness of the horizontal protruding pieces 5a, 5b (see FIG. 5), and the horizontal protruding pieces 5a, 5b are formed in the recess 9
It is dimensioned so that it can be housed in a fitted state.

Next, the operation for mounting the front bumper 1 on the front body panel 8 will be described.
It is as follows. First, an operator grips the front bumper 1 from the front side, aligns the pair of horizontal projections 5a and 5b of the front bumper 1 with the pair of recesses 9 of the front body panel 8, and moves the front bumper 1 downward. As a result, the flat protrusions 5a and 5b are fitted in the recess 9 and placed on the bottom surface 9b of the recess 9. At that time, the front bumper 1 is guided by the horizontal projections 5a, 5b and the side surface 9b of the recess 9 to guide the front body panel 8 to the front bumper 1.
The position of the hook 6 of the front bumper 1 is regulated, and the hook 6 of the front bumper 1 is inserted through the hook insertion hole 10 of the front body panel 8.

Along with this, the hook 6 and the hook insertion hole 10
By the engagement action with the peripheral portion of the front bumper 1
Is temporarily fixed to the front body panel 8.
Therefore, even if the operator releases his / her hand from the front bumper 1, the front bumper 1 is held at the proper assembly position with respect to the front body panel 8, and the front bumper 1 is temporarily fixed to the front body panel 8. Then, as shown in FIG. 2, the upper end edge of the grill part 4 of the front bumper 1 which is temporarily fixed is fastened and fixed to the front body panel 8 with bolts 11a and 11b. Further, both side portions of the bumper front surface portion 3a are bolted to the vehicle body via the brackets 12a and 12b, and the central lower portion of the bumper front surface portion 3a and the upper portions of the bumper side surface portions 3b and 3c are bolted to the vehicle body.

The front bumper 1 thus mounted on the front portion of the vehicle body has the upper surface α of the horizontal projections 5a and 5b.
Is placed substantially flush with the upper surface β around the recess 9 of the front body panel 8 (see FIGS. 4 and 5).
Thus, when the seal member 13 is arranged on the hood inner panel 2a on the rear surface side of the front hood 2 so as to correspond to the front body panel 8, when the front hood 2 is in the fully closed state, the seal member 13 is sealed. The surface (lower surface) 13a comes into flush contact (uniformly) with the series of flat surfaces formed by the upper surfaces α and β without causing unevenness.

According to the bumper mounting structure having such a structure, when the front bumper 1 is assembled to the front body panel 8, all of the pair of horizontal projections 5a and 5b and the concave portion 9 can be visually confirmed at the same time. However, since the assembling work can be performed, the assembling work can be performed easily and efficiently. Besides, the horizontal projection 5
The front bumper 1 can be regulated to the regular assembly position with respect to the front body panel 8 by the positioning action between the a and 5b and the recessed portion 9, and under that state, the hook 6 is inserted into the hook insertion hole. The front bumper 1 can be easily fastened to the front body panel 8 by easily engaging with the front body panel 8. Therefore, the front bumper 1 can be attached to the vehicle body by bolting or the like with good workability while the front bumper 1 is temporarily fixed.

Further, according to the present embodiment, the upper surfaces α of the horizontal projections 5a and 5b and the upper surface β of the front body panel 8 are flush with each other, as described above, so that they are arranged on the hood inner panel 2a. The sealing surface 13a of the sealing member 13 contacts the surfaces α and β flush with each other without causing unevenness, and good sealing performance can be secured.

The embodiment of the present invention has been described above.
The present invention is not limited to this embodiment, and various modifications and changes can be made based on the technical idea of the present invention. For example, the horizontal protrusions 5a and 5b of the front bumper 1
The shapes of the hook 6, the recess 9, and the like of the front body panel 8 can be arbitrarily changed as necessary. Needless to say, the present invention can be applied not only to the mounting structure of the front bumper 1 to the front body panel 8 but also to the mounting structure of the rear bumper to the rear body panel.

[0025]

As described above, according to the present invention, the substantially horizontal protrusion provided on the upper end portion of the bumper is fitted into the recess formed in the upper end surface of the body panel and placed on the body panel. The bumper is temporarily fixed to the body panel by engaging a hook provided on the lower surface side of the projecting piece with the hook insertion hole of the body panel, and under this state, the bumper is attached to the body panel. Because it was
When assembling the bumper to the body panel, the projecting piece can be fitted into the recessed part while visually checking both the projecting piece and the recessed part at the same time, and the assembling work can be performed easily and efficiently. Becomes Moreover, by the positioning action by fitting the protrusions into the recesses, the assembly position of the bumper with respect to the body panel can be restricted to a regular position and temporarily fixed, and therefore the work of mounting the bumper on the vehicle body is also easy. It can be performed easily and with good workability.

Further, according to the present invention, under the condition that the projecting piece is inserted into the recess and assembled on the body panel, the projecting piece and the body panel portion around the projecting piece are substantially flush with each other. Therefore, when the sealing member is arranged on the back surface of the hood, the sealing surface of the sealing member is flush with the upper surface of the protrusion and the upper surface of the body panel when the hood is fully closed. No unevenness is generated when they come into contact with each other, so that good sealing properties can be obtained.
