Description

[Detailed Description of the Invention] This invention relates to a liquid level detection device for a washing tank in an automobile.

Liquid tanks in automobiles are sometimes installed in the space between the trim that forms the interior wall of the vehicle at the rear of the vehicle and the outer panel in order to utilize the surplus space of the vehicle body (for example, as disclosed in Japanese Utility Model Application Publication No. 52-75336). ). In this configuration, when injecting liquid into the tank, it is necessary to detect the liquid level, but since this tank is sandwiched between the trim and the outer panel as described above, the liquid level cannot be detected. It is not easy to see.

As a means for detecting the liquid level in the above-mentioned case, there is one disclosed in, for example, Japanese Utility Model Application Laid-Open No. 57-114922. According to this configuration, one end of the transparent cylindrical body is inserted into the tank by a predetermined length, the liquid in the tank is allowed to enter the cylindrical body, and then the other end of the cylindrical body is closed. When the cylindrical body is removed from the tank in this state, the liquid remains inside the cylindrical body, and the liquid level in the tank can be detected by reading this liquid level.

However, even if such a liquid level detection means is applied to the above-mentioned automobile tank, it is complicated to insert and remove the cylindrical body from the tank, and moreover, when it is dark outdoors such as at night, the inside of the cylindrical body It is difficult to visually check the liquid level.

This idea was made with attention to the above-mentioned circumstances, and it allows the liquid level of the washer tank to be easily adjusted even when it is dark outdoors, and
It is an object of the present invention to enable accurate detection and to simply configure a means for detecting this liquid level.

The feature of this invention to achieve the above object is that the level gauge for the wash tank is provided on the outer surface of the vehicle body, and the level gauge is located near the combination lamp so that the level gauge is illuminated by the combination lamp. It is located at a point set in.

Examples of this invention will be described below with reference to the drawings.

In FIGS. 1 to 3, the rear part of the interior of the automobile 1 is used as a luggage compartment. Further, a door opening 2 for taking in and out luggage is formed on the rear surface of the vehicle body, and a rear door 3 is provided that allows the door opening 2 to be opened and closed.

On the other hand, trim 4 that forms the interior wall at the rear of the vehicle body
A washer tank 7 is provided between the outer panel 6 and the outer panel 6. The lower end of a communication pipe 8 is connected to the upper part of the washer tank 7, and the upper end of this communication pipe 8 is connected to the side edge 9 of the door opening 2. The upper end of this communication pipe 8 is opened to the outside of the vehicle body and serves as an injection port 8a for supplying cleaning liquid to the washer tank 7. Further, the lower part of the washer tank 7 is communicated with the backwind side via a pump (not shown).

A combination lamp 10 is provided on the outer surface of each side edge 9 of the door opening 2. The combination lamp 10 has a vertically elongated shape in which a tail lamp, a stop lamp, a back lamp, etc. are arranged vertically, and each pump has a lens 10a and a light 10b.

A level gauge 11 for detecting the liquid level of the washer tank 7 is provided on the outer surface of the side edge 9 near the combination lamp 10. The level gauge 11 is made of a transparent resin hose, and its upper and lower ends are connected to the wash tank 7 by passing through the side edges 9, respectively. Further, this level gauge 11 is provided in a drainage groove 13 between a weather strip 12 provided at the edge of the side edge 9 and the combination lamp 10.
This level gauge 11 is connected to the injection port 8a.
At the same time, the door opening 2 is covered by a rear door 3 in a closed state.

According to the configuration of the above embodiment, in the normal state where the door opening 2 is closed by the rear door 3, the level gauge 11 is covered by the rear door 3, so that the appearance is kept good, and the level gauge 11 is prevented from being soiled by muddy water or the like. Further, even when the level gauge 11 is provided protruding from the outer surface of the vehicle body, since the level gauge 11 is covered by the rear door 3, it is prevented from coming into contact with an external obstacle and being damaged.

FIG. 4 shows another embodiment, in which the automobile 1 is a passenger car, and a horizontally long combination lamp 10 is provided on the rear surface of the vehicle body, and a level gauge 11 for a wash tank is provided near the side of the combination lamp 10. It will be done. The other configurations are the same as those in the previous embodiment.

According to this invention, the level gauge is installed on the outside of the vehicle body, and since the supply of cleaning fluid to the washer tank is generally done from outside the vehicle body, when supplying cleaning fluid from outside the vehicle, the washer tank is also supplied from outside the vehicle. The liquid level can be detected, and therefore, the work of detecting the liquid level can be done easily.

Further, since the level gauge is provided near the combination lamp, even when it is dark outside, the level gauge is illuminated by the combination lamp, so that the liquid level in the washer tank can be accurately detected. In this case, a combination lamp with other functions such as a tail lamp is also used to illuminate the level gauge, so
The means for detecting the liquid level in the washer tank is simply constructed.
