Description

[Detailed Description of the Invention] The present invention relates to a liquid tank device for an automobile, and more particularly to a liquid tank device for storing a liquid that needs to be replenished, such as a window cleaning liquid.

Conventionally, this type of liquid tank device has generally been installed in the engine room, but in the engine room, in addition to the engine, various devices such as a radiator and battery are housed to maximize the limited room space. Therefore, it is extremely difficult to secure an installation space for the tank device, and even if it could be secured, it would be difficult to increase the capacity of the tank.

The present invention was devised in consideration of the above points, and its purpose is to not be limited by the installation space, and to not impair the appearance of the automobile in any way, while also making it extremely easy to replenish liquids. We are trying to provide liquid tank equipment.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A liquid tank device for an automobile according to the present invention will be explained below according to an embodiment shown in the drawings.

The automobile shown in FIG. 1 is a cab-over type light van, and a step portion 3 is provided below the opening of the front door 1 of the automobile, which is one step lower than the floor plate 2 of the vehicle body.
Side members 4, 4 extending approximately in the longitudinal direction of the vehicle body are installed at the lower part of the vehicle body.

Accordingly, in the present invention, the liquid tank 5 is supported at the lower part of the floor plate 2, and the liquid inlet 6 of the tank 5 is arranged in the vertical wall 3a of the step section 3.

That is, the embodiment shown in the figure shows a liquid tank device for storing window cleaning liquid, and a bracket 41 is attached to the side members 4, 4 by welding as appropriate, and the window cleaning liquid is supplied through this bracket 41. A liquid tank 5 containing the liquid is removably attached to the lower part of the floor plate 2 by bolts 42.

On the other hand, a part of the vertical wall 3a of the step portion 3 is bent inward to form the front door 1.
By forming an inclined wall part 30 whose outer wall surface is angled upward toward the opening of the tank, and by making the liquid filling port 6 of the tank 5 face the through hole 31 formed in this inclined wall part 30. The liquid injection port 6 is designed to open upwardly toward the front door 1, and a cap 7, one end of which is fixed to the inclined wall portion 30, is fitted into the through hole 31 to open the liquid injection port 6 upwardly toward the front door 1. The liquid port 6 is about to be closed.

Furthermore, in the embodiment shown in the figure, in order to prevent the liquid tank 5 from being seen from outside the vehicle, the bottom wall portion 51 of the tank 5 on the step portion 3 side is inclined diagonally upward as it goes toward the front door 1. .

In the figure, 50 is a washer pump installed in the liquid tank 5, and 32 is a garnish that integrally covers the outer surfaces of the vertical wall 3a and floor wall 3b of the step section 3. A notch hole 33 is provided at a location corresponding to the wall portion 30.

Also, a portion of the ribs 35, 35 formed on the lower surface of the garnish 32 is cut out to form a discharge space S between the garnish 32 and the floor wall 3b of the step section 3.

Further, 34 is a shield rubber fitted around the periphery of the through hole 31 of the inclined wall portion 30, and 20 is a floor carpet covering the upper surface of the floor plate 2.

To replenish the cleaning liquid into the liquid tank 5, first open the front door 1, remove the cap 7, and inject the appropriate cleaning liquid from the liquid injection port 6. Since the opening 6 is angled upward toward the front door 1, the cleaning liquid can be easily injected.

Furthermore, even if a portion of the cleaning fluid leaks from the fluid inlet 6, it will flow along the floor wall 3b of the step portion 3 and be discharged outside the vehicle.

As described above, according to the present invention, since the liquid tank is supported under the floor plate of the vehicle body, the installation space for the liquid tank is not limited, and the capacity of the liquid tank can be freely set.

In addition, since the liquid filling port of the tank is arranged on the vertical wall of the step portion formed at the door opening, even if liquid leaks from the liquid filling port, it will not stain the floorboard of the vehicle body. Not only can the liquid be discharged out of the car along the floor wall, but since the liquid injection port is always hidden by the door, there is no risk of damaging the appearance of the car, and furthermore, the liquid can be discharged from the vehicle from passengers seated in the seats. Since the mouth is not visible, there is no risk of deteriorating the aesthetics of the passenger compartment.

In addition, since the liquid injection port is arranged on the vertical wall of the step part, the liquid injection port does not become an obstacle when the passenger uses the step part to get on and off the vehicle, so there is no risk of tripping. It is.
