Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the structure of an automobile washer tank.

[0002]

2. Description of the Related Art As a structure of a washer tank of an automobile, for example, see FIG. 9 (see Japanese Utility Model Laid-Open No. 61-54923).
As shown in FIG. 1, a pipe 104 is provided in a washer tank 102 arranged in an engine room 100 of an automobile, and the pipe 1 extends to the vicinity of a dashboard 106.
There is one in which the water in the washer tank 102 is jetted to the front window panel 110 by the No. 04 washer nozzle 108. Reference numeral 112 is a wiper device.

[0003]

However, in the structure of the conventional vehicle washer tank, since the washer tank 102 is arranged in the engine room 100, the capacity is also limited by the space limitation of the engine room 100. . Further, the front wheel 114 load is also increased with respect to the front-rear distribution of the vehicle weight, and improvement is desired from the viewpoint of steering stability. Therefore, the present invention has been made in view of the above points, and an object thereof is to increase the degree of freedom with respect to the washer tank capacity,
It is intended to provide a washer tank for an automobile capable of improving steering stability.

[0004]

A washer tank for an automobile according to claim 1 of the present invention covers a hollow tank main body supported by a trunk floor panel and having a substantially perfect circular shape in plan view, and the tank main body. In this way, a spare tire can be supported on the tank body, and the tank body is constituted by a cap capable of sealing the water injection port. According to the second aspect of the present invention, in the cap, the cap main body having the female screw portion screwed into the screw portion of the water injection port of the tank main body and the side portion for firmly holding the edge portion of the spare tire wheel are integrally formed. It is formed.
According to a third aspect of the present invention, the cap body has a second end portion of the coil spring, the first end portion of which is locked in the mounting bolt hole of the spare tire wheel, in a direction to prevent loosening of the female screw portion. It is formed by forming a stop. According to claim 4 of the present invention, the cap main body is engaged with the projection formed on the lowermost end of the screw portion of the water injection port when the cap main body is screwed to the lowermost end, and the engagement is performed. The releasing member is arranged so as to be detachable from the protrusion only when the member is biased in the direction opposite to the direction.

[0005]

According to the washer tank for an automobile of claim 1 of the present invention, since the tank main body is arranged by utilizing the dead space of the hollow portion of the spare tire, the flexibility of the tank capacity is increased. Also, since the tank body is supported by the trunk floor panel, the rear wheel load is increased,
Not only can the steering stability be increased, but the means for attaching the spare tire will be cheaper. Further, by sealing the water injection port of the tank body with the cap, it becomes possible to support the spare tire on the tank body. According to the vehicle washer tank of the second aspect of the present invention, the edge portion of the spare tire wheel can be fixed to the side portion of the cap simply by screwing the cap onto the screw portion of the water injection port of the tank body.

According to the vehicle washer tank of claim 3 of the present invention, when the cap is completely screwed into the screw portion of the water injection port of the tank body, one end of the coil spring is used as a mounting bolt hole for the spare tire wheel. By locking and locking the other end of the coil spring in the locking part of the cap in the direction of preventing the loosening of the female screw part, a reliable cap slack preventing effect can be obtained. According to the vehicle washer tank of claim 4 of the present invention, when the cap is screwed to the screw portion of the water inlet of the tank body, the protrusion formed on the lowermost end of the screw portion of the water inlet is provided. By engaging the release member of the cap main body, a reliable cap slack prevention effect can be obtained. Of course, the cap can be removed from the water injection port by releasing the engagement of the release member with the protrusion.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. A structure of a vehicle washer tank according to an embodiment of the present invention will be described with reference to FIGS. 1 to 6. In the figure, a washer tank 1 for an automobile is a hollow tank body 3
And a cap 5. The hollow tank body 3
Are fixed brackets 9 and 9 on the trunk floor panel 7.
·········· It is supported via screws 10, 10, ... And has a substantially perfect circular shape in a plan view. Reference numerals 11 and 13 denote ribs and embossments formed on the hollow tank body 3, respectively.
By ensuring the rigidity of the spare tire 15 and matching the shape of the spare tire wheel 17 of the spare tire 15, the rattling of the spare tire 15 can be prevented. The cap 5 is arranged so as to cover the tank body 3 with the spare tire 15, and then the water injection port 1 of the tank body 3 is provided.
By sealing 9 the spare tire 15 on the tank body 3
Can be supported. More specifically, the cap 5 includes a cap body 25 having a female screw portion 23 that is screwed into the screw portion 21 of the water injection port 19 of the tank body 3, and the spare tire 1.
The spare tire wheel 17 of No. 5 is integrally formed with the side portion 27 that holds the edge portion 18 of the spare tire wheel 17.

More specifically, in the cap 5, one end 32 of the coil spring 31 is locked in the mounting bolt hole 29 of the spare tire wheel 17, and then the other end 33 of the coil spring 31 is attached to the female screw portion 23. A ring 35 is formed as a locking portion that locks in the slack prevention direction. According to this embodiment, the tank body 3 has the spare tire 1
Since it is arranged by utilizing the dead space of the hollow portion 16 of No. 5, the degree of freedom with respect to the tank capacity is increased. Further, since the tank body 3 is supported by the trunk floor panel 7, not only the rear wheel (not shown) load can be increased and the steering stability performance can be increased, but also the means for attaching the spare tire 15 becomes inexpensive. Further, by plugging the water injection port 19 of the tank body 3 with the cap 5, it becomes possible to support the spare tire 15 on the trunk floor panel 7 on the tank body 3. Furthermore, the edge portion 18 of the spare tire wheel 17 is capped by simply screwing the cap 5 into the screw portion 21 of the water injection port 19 of the tank body 3.
It can be held by the side portion 27 of the cap body 25.

Further, when the cap 5 is completely screwed into the screw portion 21 of the water injection port 19 of the tank body 3, one end 32 of the coil spring 31 is locked in the mounting bolt hole 29 of the spare tire wheel 17, and the coil The other end 33 of the spring 31 is attached to the cap 5 in the direction to prevent the female screw 23 from loosening.
By locking the ring 35 as a locking portion of the cap 5, a reliable effect of preventing the cap 5 from loosening can be obtained. 7 and 8
A structure of a vehicle washer tank according to another embodiment of the present invention will be described with reference to FIG. The main difference of this embodiment from the previous embodiment is the cap loosening prevention structure. In the figure, the cap body 41 has a releasing member 45 which engages with the projection 43 formed at the lowermost end of the screw portion 21 of the water injection port 19 when the cap body 41 is screwed to the lowermost end. The release member 45 is always biased in the engaging direction by the leaf spring 47, but can be detached from the protrusion 43 only when biased in the direction opposite to the engaging direction. 49 is a pin that rotatably supports the release member 45 on the cap body 41. Therefore, according to this embodiment, when the cap body 41 is screwed to the screw portion 21 of the water inlet 19 of the tank body 3, the protrusion formed at the lowermost end of the screw portion 21 of the water inlet 19 By engaging the release member 45 of the cap body 41 with the cap 43, a reliable effect of preventing the cap 5 from loosening can be obtained. Of course, the cap 5 can be removed from the water injection port 19 by releasing the engagement of the release member 45 with the protrusion 43.
