Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle washer tank mounting structure.

[0002]

2. Description of the Related Art Conventionally, when a washer tank for storing wash water used in a vehicle washer device is attached to a vehicle, a bracket for supporting the washer tank is fixed to a panel on the vehicle body side while the bracket is attached to the rear surface of the washer tank. It is known that a holding groove for slidingly locking is provided on the. As an example, the actual exploitation 56-1684
No. 52, for example.

[0003]

However, most of the washer tanks used in such conventional examples are formed by blow molding a synthetic resin material. However, in such a washer tank, the wash water is full and the environment is cold. If it is placed and frozen, the entire washer tank is deformed due to the expansion of the wash water and the retaining grooves are locally deformed so that the spacing between the retaining grooves on both sides becomes larger and the washer tank falls off from the support bracket. There's a problem. As a countermeasure for this, a method of increasing the fitting margin between the holding groove and the bracket can be considered, but the problem of poor productivity and increased cost due to restrictions on blow molding cannot be solved.

[0004]

According to the present invention, a bracket for supporting a washer tank is provided on a vehicle body side panel, and a holding groove for a washer tank into which an outer edge portion of the supporting bracket is inserted is provided on a back surface of the washer tank. In those having bracket insertion parts formed on both sides,
A contact surface is formed on the back surface outside the bracket insertion portion, with which the stopper abuts, and when the outer edge portion is inserted into the holding groove, the stopper abuts on the abutment surface to prevent deformation of the holding groove. It is characterized in that it is provided on the vehicle body side panel.

[0005]

According to the above construction, when the wash water is frozen in the washer tank in a cold environment when the wash water is full, the washer tank is deformed due to expansion of the wash water,
A stopper provided on the vehicle body side panel with a deformation amount much smaller than the deformation amount of the washer tank comes into contact with the outer abutment surface of the bracket insertion part to prevent deformation in the direction of expanding the gap between the holding grooves on both sides. By acting, the holding groove is prevented from coming off from the outer edge portion of the support bracket of the washer tank, and the washer tank is prevented from falling off.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a washer tank showing a first embodiment of the present invention, and FIG. 2 is a partial cross-sectional view of the washer tank taken along the line BB in FIG.
FIG. 3 is a perspective view of a support bracket for a washer tank according to the first embodiment of the present invention.

In FIGS. 1 to 3, reference numeral 1 denotes a washer tank having a water injection port 1a on an upper surface which is made of blow-molded resin having some elasticity and is provided on a rear surface 2 of the washer tank 1. The insertion portion 3 of the support bracket 10 for mounting the washer tank 1 on the vehicle body is formed by being slightly depressed from the back surface 2 of the washer tank 1, and the support bracket is formed on both sides of the insertion portion 3 from the direction of arrow A in FIG. It has a holding groove 4 into which 10 is inserted, and a recess 5 into which the projection 11 at the tip of the supporting bracket 10 is inserted at the upper end of the insertion portion 3 in the upward direction.
A bank-shaped portion 7 is formed integrally with the opening 6 of the holding groove 4 outside the holding groove 4 and protrudes from the back surface 2 of the washer tank 1 during blow molding. A top portion 8 that most protrudes and a contact surface 9 that contacts a stopper 22, which will be described later, that forms a slope 9 that extends from the top portion 8 to the rear surface 2 are formed.

On the other hand, the support bracket 10 of the washer tank 1 has a body portion 1 to which the bracket 10 is fixed to the vehicle body panel 20.
2 and the holding groove 4 of the washer tank 1 in its outer edge 1
3 has a pair of ear-shaped portions 13a that are fitted in a concavo-convex shape, and a protrusion 11 that is inserted into the recess 5 at the upper end of the insertion portion 3. On the other hand, on the vehicle body panel 20 forming a part of the vehicle body, two beads 21 extending in the vertical direction are provided as stoppers 22 for suppressing the deformation of the washer tank 1 attempting to expand in the lateral direction due to freezing of the washing water. Has been.

Then, the supporting bracket 10 fixed to the vehicle body panel 20 by welding is inserted into the holding groove 4 of the washer tank 1 from the direction of arrow A in FIG. 1, and the projection 11 of the supporting bracket 10 is inserted into the inserting portion 3 When the support bracket 10 and the washer tank 1 are integrated by inserting up to the recess 5 at the tip of the washer 12, the position of the body portion 12 from the washer tank 1 is the washer from the line connecting the tops 8 of the both bank-like portions 7. A height dimension of the supporting bracket 10 is formed so as to be located outside the tank 1, and a bead 21 as the stopper 22 is provided so as to contact the contact surface 9.

According to this structure, the washing water in the synthetic resin washer tank 1 mounted on the vehicle is frozen, and even if the washing groove 1 of the washer tank 1 is deformed in the direction in which the distance between the holding grooves 4 is widened, The abutment surface 9 abuts a stopper 22 provided on the vehicle body panel 20 to prevent the deformation from occurring, and prevents the washer tank 1 from falling out of the holding groove 4 of the supporting bracket 10 for supporting. be able to.

Further, in the second embodiment shown in FIG. 4, the coupling between the supporting bracket and the holding groove of the washer tank is constructed in the same manner as in the first embodiment, and the abutting portion of the stopper and the stopper. Only the configuration of is different. Hereinafter, components having the same configuration will be denoted by the same reference numerals as those in the first embodiment. That is, the concave groove 3 is formed on the back surface 30 of the washer tank 1.
1 is a washer tank 1 along the side of the holding groove 4.
Is formed integrally with the supporting bracket 10, and a stopper 33 is formed by bending both ends of a stopper plate 32 made of a metal plate connected to the supporting bracket 10 to the connecting side of the supporting bracket 10 at substantially right angles. Is fitted in the concave groove 31 so that the washer tank 1 and the stopper plate 32 are integrally combined. The stopper plate 32 is fixed to the vehicle body panel 34, and the washer tank 1 is attached to the vehicle together with the supporting bracket 10. According to this configuration, in addition to the effect similar to that of the first embodiment, the bead 21 as in the first embodiment does not have to be provided on the vehicle body panel 20, so that the location of the washer tank 1 can be reduced. The advantage that the degree of freedom is increased is obtained, and further, since the washer tank 1 having the shape in which the rear surface 30 of the washer tank 1 is brought close to the vehicle body panel 34 can be formed, the effect that the washing water volume of the washer tank 1 can be set large can be obtained. ..

[0012]

According to the present invention, the following effects can be obtained. If the washer tank is full of washing water and is frozen in a cold environment and freezes, the stopper provided on the panel on the vehicle body side contacts the contact surface provided on the outside of the washer tank support bracket insertion part. Since the deformation of the washer tank in the direction of expanding the holding groove is prevented, the holding groove is prevented from coming off the outer edge portion of the supporting bracket, and the washer tank is prevented from falling off. In addition, since the molding conditions of the synthetic resin can be the same as before, there is an effect that an inexpensive mounting structure can be obtained without lowering the productivity of the washer tank.
