Description

[Detailed Description of the Invention] The present invention relates to a liquid tank for an automobile, such as a rear wash tank, which is housed in a space between an inner panel and an outer panel of an automobile, such as a trunk room, a passenger compartment, or a door.

The rear wash tank supplies water to wash the rear window glass and is used together with the rear wiper. Conventionally, this rear wash tank has been constructed by storing a box-shaped molded tank in the space between the inner panel and the outer panel of the trunk compartment, and connecting a bellows hose to the liquid filling port of this box-shaped molded tank, or The bag-shaped tank was configured to be removably housed within the space.

However, the former method uses a bellows hose, which is expensive, and requires the effort of holding the bellows hose while supplying the water. In the case where a hole is provided in the panel and one end opening of the bellows hose is fixed to the hole, there is a problem in that the processing for this fixing further increases the cost. In addition, even in the case of the latter, there is the hassle of having to take out the tank every time the liquid is supplied, and there is also the problem of the tank hitting the inner or outer panel due to vibrations when the vehicle is running, producing a banging sound. It was hot.

In this way, conventional rear wash tanks do not have very good fluid supply performance, and
There were problems such as high costs and the generation of hitting noises due to vibrations when the vehicle was running.

The present invention has been made to solve the above problem, and includes rotatably connecting one end opening of a substantially crank-shaped liquid supply pipe to the liquid injection port of a liquid tank.
The water supply pipe is configured so that when the liquid supply pipe is rotated using the opening at one end as a fulcrum, the opening at the other end of the pipe comes out through a window hole provided in the inner panel or outer panel. It is a feature.

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

Figure 1 is a perspective view of a car equipped with the automotive liquid tank of the present invention, seen from the rear side, and Figure 2 shows the automotive liquid tank of the present invention stored in the space between the inner panel and outer panel of the trunk compartment. FIG. 3 is a partially cutaway front view taken out from the same space, and FIG. 4 is a plan view of the same.

Reference numeral 1 in the figure is a trunk room. A box-shaped liquid tank 5 is housed in a space 4 between an inner panel 2 and an outer panel 3 of this trunk room 1. In FIG. 2, a tank bracket 6 is fixed to the inner surface of the outer panel 3 with bolts and nuts 7, and a liquid tank 5 is supported on this tank bracket 6. Therefore, it is also possible to remove the liquid tank 5 from the tank bracket 6, take it out of the space 4, and supply the liquid outside the vehicle.

A substantially crank-shaped liquid supply pipe 8 is provided at the liquid injection port 5a provided near one end of the upper surface of the liquid tank 5.
One end opening 8a is rotatably connected via an O-ring. The liquid supply pipe 8 is made of hard synthetic resin, and has one end opening 8a bent downward at a substantially right angle, and the other end opening 8b bent upward at a substantially right angle.
An intermediate portion 8c between the opening 8b and the other end opening 8b is substantially horizontal and extends straight. The other end opening 8b serves as a liquid injection port when supplying liquid, and there is a cap 10 therein.
is removably provided. In addition, the intermediate portion 8c
When the liquid supply pipe 8 is rotated approximately 90 degrees toward the front using the opening 8a at one end as a fulcrum, the opening 8b at the other end
is set to a length that extends out from the window hole 2a of the inner panel 2.

Therefore, when supplying liquid to the liquid tank 5,
Tilt the trim door 11a of the trim plate 11 provided along the inner panel 2 toward the front to open the window hole 2a of the inner panel 2, and rotate the liquid supply pipe 8 approximately 90 degrees toward the front with its one end opening 8a as a fulcrum. By simply moving the liquid supply pipe 8, the other end opening 8b, which serves as a liquid injection port, can be pulled out. (See Figure 2).
After doing this, if the cap is removed from the other end opening 8b and washer water is supplied from a hand-held container, the liquid can be easily supplied.

A projecting piece 12 having an engaging hole is provided on the upper surface of the liquid tank 5 near the other end, and an engaging protrusion is provided on the lower surface of the intermediate portion 8c of the liquid supply pipe 8 near the other end opening 8b. When the projecting piece 13 is provided and the liquid supply pipe 8 is housed in the space 4,
The engagement holes of these projecting pieces 12 and 13 engage with the engagement protrusions. Therefore, the liquid supply pipe 8 is prevented from swinging about its one end opening 8a as a fulcrum due to vibrations when the vehicle is running.

Further, the liquid tank 5 is provided with a pump motor 14, and the pump motor 14 supplies washer water in the liquid tank 5 to the rear window glass, and the rear window glass is cleaned using a rear wiper.

In the figure, 15 is the floor of the trunk room 1.

As mentioned above, the automotive liquid tank of the present invention is not limited to the space 4 between the inner panel 2 and the outer panel 3 of the trunk compartment 1, but is also applicable to, for example, the space between the door and the inner panel and outer panel of the passenger compartment. It may be stored in Furthermore, in addition to washer water for cleaning the rear window glass, it may also be used to store drinking water or the like. Furthermore, a window hole may be provided in the outer panel 3, and the other end opening 8b of the liquid supply pipe 8 may be configured to exit from the window hole.

As explained above, according to the automotive liquid tank of the present invention, one end opening of the substantially crank-shaped liquid supply pipe is rotatably connected to the liquid filling port of the box-shaped tank. The liquid supply pipe is configured such that when the liquid supply pipe is rotated using the opening at one end as a fulcrum, the opening at the other end of the pipe comes out from the window hole provided in the inner panel or the outer panel. This eliminates the need to support the inlet by hand or take out the tank itself when supplying fluid, improving fluid supply performance, and eliminating the need to use a bellows hose or apply special processing to the panel. Since the tank is not a bag type, it does not generate any banging noise due to vibrations when the vehicle is running.
