Description

[Detailed description of the invention] [Industrial field of application] The invention is used in vehicles, especially automobiles, to prevent damage to the rear balance panel caused by flying stones such as pebbles from the road surface due to the rotation of the rear wheels. Regarding the structure of the stone-flying prevention plate.

[Conventional technology]

Generally, when an automobile starts or runs, as shown in FIG. 4, the rotation of the rear wheels 10 causes pebbles 12, etc. from the road surface to be thrown up and thrown behind the rear wheels 10, colliding with the rear parts of the vehicle body 14.

A rear floor pan 16, a rear balance panel 18, etc. are provided at the rear lower end of the vehicle body 14, and the rear balance panel 18 is a member that is frequently collided with the pebbles 12 and the like.

Therefore, a pebble 12 was placed on the rear balance panel 18.
The fifth protector 20 is for preventing collisions such as
As shown in the figure, they are disposed below the vehicle body 14 and behind the rear wheels 10 on the left and right sides in the width direction of the vehicle body 14, respectively.

As shown in FIG. 6A, this protector 20 is fixed to the rear floor pan 16 with screws 22 or grips (not shown).

In another conventional example, as shown in FIG. 6B, the protector 20A is fixed to the rear balance panel 18 with screws 22A or grips (not shown).

However, as shown in FIG.
The lower ends of the rear balance panels 18 and 1
Since it is disposed above the lower end of the rear balance panel 8A, it causes pebbles 12 and the like to collide with the lower end of the rear balance panels 18 and 18A.

In consideration of the above fact, the chipping-resistant structure of the rear balance panel disclosed in Utility Model Application Publication No. 55-31734 has a protector 2 as shown in the example shown in FIG.
4 is provided with hooks 26, and these hooks 26 are engaged with the lower end of the rear balance panel 28 and the working hole 30, so that the lower end of the rear balance panel 28 can be covered. Further, since the working hole 30 and the hook 26 of the rear balance panel 28 are covered by the bumper 32, the structure is designed to have no problem in terms of appearance.

[Problem that the invention attempts to solve]

However, the hook 26 is attached so as to protrude toward the rear of the vehicle from the rear balance panel 28, and the bumper 32 that covers the hook 26 is arranged so that its ends in the vertical direction of the vehicle body do not come into contact with the hook 26. Since the bumper 32 is arranged so as to cover the working hole 30 without causing any problems in appearance, there is a problem in that the position of the bumper 32 in the vertical direction of the vehicle body is limited.

In addition, the protector 24 is made of resin and is formed into a plate shape, which is bent to form a hook 26 along the width direction, and has a complicated shape, so it is said that the work efficiency in manufacturing it as a mass-produced product is low. There is a problem.

The present invention takes the above facts into account, and makes it possible to obtain a stone-flying prevention plate structure that is easy to manufacture and can protect the rear balance panel without limiting the positional relationship of components such as bumpers on the rear balance panel. It is a purpose.

[Means for solving problems]

In the stone-flying prevention plate structure according to the present invention, the lower part of the rear balance panel has a first wall portion bent toward substantially downward of the vehicle body, and the end portion of this first wall portion on the lower side of the vehicle body is approximately A shelf portion bent forward and provided; and a second shelf portion provided with an end portion of the shelf portion on the substantially front side of the vehicle body bent substantially downwardly of the vehicle body.
a wall portion made of resin and covering at least the second wall portion and abutting the first wall portion and the second wall portion from mutually opposite directions along the approximately longitudinal direction of the vehicle body, and the shelf portion; and a protector that holds the vehicle body from substantially the top and bottom directions.

[Effect]

According to the stone flying prevention plate configured as described above, the protector is attached to the lower part of the rear balance panel so as to cover at least the second wall portion. When the protector is attached to the lower portion of the rear balance panel, it abuts the first wall portion and the second wall portion from directions opposite to each other along the approximately longitudinal direction of the vehicle body.
Therefore, movement of the protector in the approximately longitudinal direction of the vehicle body is restricted. Furthermore, when the protector is attached to the lower part of the rear balance panel, the protector holds the shelf section from substantially the top and bottom directions of the vehicle body. Therefore, movement of the protector in a substantially vertical direction of the vehicle body is restricted. Therefore, when the protector is attached to the lower part of the rear balance panel, the movement of the protector in the longitudinal direction and the vertical direction of the vehicle body is simultaneously restricted, so after the protector is attached to the lower part of the rear balance panel, The mounting position will not shift.

Further, since the rear balance panel has no protrusion or hole in the center of the rear surface of the vehicle body, it does not limit the mounting position of a member such as a bumper.

After installing the protector, when the vehicle starts or when the vehicle is in normal running conditions, pebbles thrown up by the rear wheels will collide with the protector, reducing the possibility of a direct collision above the rear balance panel. . In addition, the protector is
It can be made into an extrusion molded product with a simple shape.

Further, pebbles, muddy water, etc. (not shown) that directly collide with the protector 42 are reflected by the collision and are discharged or flowed down onto the road surface.

As described above, the stone flying prevention plate structure of this embodiment allows the protector 42 to move closer to the rear wheel 48 side, thereby reducing the possibility that pebbles, muddy water, etc. (not shown) flying up from the rear wheel 48 will directly collide with the rear balance panel 36. can be reduced.

Furthermore, since the rear balance panel 36 has no protrusion or hole in the center of the rear surface of the vehicle body 34, it does not limit the mounting position of members such as the bumper 40.

In this embodiment, the protector 42 prevents the rear balance panel 36 from being damaged and rusted by pebbles, muddy water, etc., but as shown in FIGS. 1 and 2,
It may be used in combination with the conventional protector 20. Alternatively, the protector 42 and the protector 20 may be integrally molded.

Further, although the rear balance panel 36 is bent in a step-like manner to form a sloped shelf portion 44 and a fitting shelf portion 46, a separate member is attached to the rear balance panel 36.
It is also possible to fix this and provide a shelf section on this.
