Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a rear bumper mounting structure, and in particular, a part of a vehicle body-side sealing surface with which a sealing piece of a weather strip disposed at an opening peripheral edge of a vehicle body abuts. The present invention relates to a structure for using the as a bumper mounting portion.

[Conventional technology]

Generally, in a one-box car or the like, an opening is formed in the rear portion of the vehicle body, and the opening portion can be opened and closed by a back door, which allows loading and unloading of luggage from the rear portion of the vehicle body. FIG. 4 shows a one-box car whose rear portion can be opened and closed. In the figure, reference numeral 1a is a rear opening formed in the rear of the vehicle body 1, and the back door 2 is attached to the upper portion thereof via a door hinge 2a. Further, a weather strip 3 is attached to the rear opening 1a along the periphery of the opening, and the weather strip 3 seals between the peripheral edge of the back door 2 and the rear peripheral edge 1b of the vehicle body. .

As shown in FIG. 5, the weather strip 3 has a structure in which a mounting portion 3a having a U-shaped cross section, a seal piece 3b on the vehicle body side, and a seal piece 3c on the back door 2 side are integrally formed.
An inner locking piece 3d is formed inside the mounting portion 3a, and the mounting portion 3a is a flange of the vehicle body rear upper part and a lower panel 4,5 constituting the lower part of the rear opening peripheral edge portion 1b. The overlapping portions of 4a and 5a are fixed to the opening peripheral edge portion 1b by being held by the locking piece 3d. Further, the vehicle body side seal piece 3b is integrally formed on the lower side portion of the mounting portion 3a,
The tip is in contact with the seal surface portion 5b below the flange overlapping portion. The door-side sealing piece 3c is formed so as to project from the back side of the mounting portion 3a, and seals between the peripheral portion of the back door 2 and the weather strip body.

Further, a mounting seat surface portion 5c is formed in a portion of the upper panel 5 below the sealing surface portion 5b so as to project slightly outward from the sealing surface portion 5b. The mounting flange 6a at the upper edge of the rear bumper 6 is fixed to the mounting seat surface 5c of the upper panel 5 by bolts 7a and nuts 7b.

[Problems to be solved by the invention]

However, in the conventional rear bumper mounting structure, since the sealing surface 5b is secured along the peripheral edge of the rear opening 1a of the vehicle body, the mounting seat surface portion 5c of the rear bumper 6 is set. The distance from 4a, 5a to the bumper mounting portion becomes large, that is, the bumper mounting portion must be lowered below the seal surface portion 5b, and the mounting bolt 7a for the rear bumper 6 from the gap at the lower end of the back door 2
However, there is a problem that the appearance is not good.

Further, since the bumper mounting seat surface portion 5c is projected to the seal surface portion 5b, water or the like is accumulated in this step portion when washing the vehicle.
If water is further applied in this state, the accumulated water will be pushed up and the water pressure will increase, and it may penetrate inside the vehicle body from between the seal surface portion 5b and the seal piece 3b along the inside of the weather strip attachment portion 3a. There was a problem.

The present invention has been made to solve such a problem, and the rear bumper can be mounted close to the weather strip mounting position on the vehicle body side, that is, above, and the intruding water in the weather strip can be immediately discharged. Therefore, it is an object of the present invention to obtain a rear bumper mounting structure in which the rear part of the vehicle body looks good, and cleaning water and the like do not enter the vehicle interior.

[Means for solving problems]

The mounting structure of the rear bumper according to the present invention forms a sealing surface portion on the edge of the rear opening of the vehicle body against which the sealing piece of the weather strip abuts, and immerses a portion of the sealing surface portion below the opening and the portion following the opening. This is characterized in that a recessed recessed portion is formed and the mounting flange of the rear bumper is fixed to the bottom surface of the recessed recessed portion.

[Action]

In this invention, a part of the sealing surface portion of the lower edge of the rear opening of the vehicle body on which the seal piece of the weather strip abuts and a portion following the sealing surface portion are recessed to form a concave recessed portion, and the rear bumper is attached to the recessed portion. Since the flange is fixed and a part of the sealing surface is also used as the mounting seat surface portion of the rear bumper, the mounting position of the rear bumper can be brought close to the weather strip mounting position, that is, can be set at a high position. Thus, the mounting portion of the rear bumper on the vehicle body side can be hidden by the lower edge portion of the back door, and the appearance of the rear portion of the vehicle body can be improved.

Further, since the concave recessed portion is covered with the mounting flange of the bumper, it is possible to avoid the deterioration of the appearance due to the provision of the recessed portion.

Further, since the mounting position of the rear bumper can be brought closer to the weather strip side, it is also advantageous in securing a mounting space for the rear bumper.

Furthermore, since a part of the seal surface portion with which the seal piece of the weather strip abuts is recessed to form the recessed recessed portion, a gap is formed between the seal surface portion and the seal piece, and the seal strip is inserted into the weather strip. The invading wash water or the like can be immediately discharged from the gap. As a result, the water pressure does not increase even when a large amount of water is applied when washing the car, and the water does not enter the vehicle interior side.

〔Example〕

 An embodiment of the present invention will be described below with reference to the drawings.

1 to 3 are views for explaining a mounting structure of a rear bumper according to an embodiment of the present invention, and FIG. 1 is a partial sectional view of a rear bumper mounting portion (corresponding to a portion A in FIG. 4). A perspective view, FIG. 2 is a sectional view taken along the line II-II of FIG. 1, FIG. 3 (a) is a sectional view taken along the line IIIa-IIIa of FIG. 2, and FIG. 3 (b) is a sectional view of FIG.
It is a IIIb-IIIb line sectional view. In the figure,
The same reference numerals as those shown in the drawings indicate the same or corresponding parts, and 5c is a part of the lower panel 5 corresponding to the lower edge of the vehicle body rear opening 1a (hereinafter referred to as the lower panel opening vicinity), and the lower panel opening vicinity 5c is Seal strip 3b for weather strip 3
Is also used as a sealing surface that abuts against and a mounting surface of the rear bumper 6.

That is, in the lower panel opening vicinity portion 5c, a recessed recessed portion 5d is formed by partially recessing it. The concave recessed portion 5d is formed from the flange 5a portion of the lower panel 5 to the seal piece.
It extends beyond the contact portion 5e with 3b to the lower side thereof.
In this concave recessed portion 5d, a gap 8 is formed between the seal piece 3b and the surface of the lower panel opening vicinity portion 5c. Then, the mounting flange 6b of the rear bumper 6 is fastened and fixed by a bolt 7a and a nut 7b to a portion of the recess 5d below the contact portion 5e. Further, the mounting flange 6b forming portion of the rear bumper 6 is made into a concave shape in accordance with the shape of the recessed recessed portion 5d, but this recessed portion 6c is slightly narrower than the recessed recessed portion 5d. A gap 9 is formed between them (see the portion B in FIG. 3 (b)).

Next, the function and effect will be described.

In such a rear bumper mounting structure, the vehicle body rear opening 1a
5c corresponding to the lower edge (near the lower panel opening)
Since the concave recessed portion 5d is formed on the rear bumper 6 and the rear bumper 6 is attached thereto, a part of the sealing surface with which the seal piece 3b of the weather strip 3 abuts can also be used as a bumper mounting portion for fixing the rear bumper 6 to the flange 6b. The rear bumper 6 can be set at a higher position on the weather strip side than the conventional one. As a result, the mounting bolt 7a for the rear bumper 6
And the like can be hidden by the lower end edge of the back door 2, and the appearance of the rear part of the vehicle body can be improved (see FIG. 2). Further, since the mounting position of the rear bumper 6 can be brought closer to the weather strip side, it becomes easy to secure the rear bumper mounting space.

Further, since the recessed portion 5d is formed by recessing a part of the contact portion 5e with which the seal piece 3b of the weather strip 3 abuts, a recessed portion 5d is formed between the seal piece 3b and the corresponding contact portion 5e. A gap 8 is created (see FIG. 3 (a)), and as shown in FIG. 1, the cleaning water W or the like that has entered the weather strip can be immediately discharged from the gap 8. Then, the water discharged from the weather strip 3 is rear bumper 6
Flows down the surface of the vehicle and the gap 9 between the side walls and falls from the vehicle body. Therefore, cleaning water and the like will not enter the interior of the vehicle through the inside of the weather strip 3. Further, since the recessed recessed portion 5d is covered with the mounting flange 6b, it is possible to avoid deterioration of appearance due to the formation of the recessed portion 5d.

In the above embodiment, the recessed portion 6c of the rear bumper 6 is used.
Although the gap 8 is formed by making the gap smaller than the concave recessed portion 5d of the lower panel opening vicinity portion 5a, the size and shape may be such that both are fitted without a gap.

[Effect of device]

As described above, according to the rear bumper mounting structure of the present invention, a part of the sealing surface portion with which the sealing strip of the weather strip abuts is also used as the mounting seat surface portion of the rear bumper. It can be set closer to the mounting position, that is, at a higher position. As a result, the mounting portion of the rear bumper on the vehicle body side can be hidden by the lower edge portion of the back door, and the appearance of the rear portion of the vehicle body can be improved. Further, since the mounting position of the rear bumper can be brought closer to the weather strip side, it is also advantageous in securing a mounting space for the rear bumper.

In addition, since a part of the seal surface portion with which the seal piece of the weather strip abuts is recessed, a gap is created between the seal piece and the seal surface portion in this recessed recessed portion, and the seal strip penetrates into the weather strip. There is also an effect that the cleaning water etc. can be immediately discharged from the gap.

As a result, it is possible to realize a rear bumper mounting structure in which the rear part of the vehicle body looks good and cleaning water and the like do not enter the vehicle interior.
