Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a washer nozzle provided on a hood panel so as to spray washer fluid toward the windshield of an automobile.

[Problems that conventional technology and ideas try to solve]

If the washer nozzle is fixed to the hood panel, it can be oriented in an optimal position toward the glass surface, but this is not aesthetically pleasing. For this reason, it has been possible to accommodate the fuel in a concealed area or in a cowl upper panel, but this has the problem of sacrificing the injection angle.

Therefore, an object of the present invention is to provide a washer nozzle that protrudes from the hood panel surface only when activated.

[Means for solving problems]

In order to achieve this objective, the present invention provides a lid 1 whose front end of the vehicle body is hinged to a notch 1a formed in the hood panel 1 near the windshield 3 side.
2, 22, and a nozzle body 13, 23 facing the windshield 3 side is provided on the back side of the lid 12, 22, and a tube 15, which is movable upward.
25 to the wash tank pump.

Note that the symbols in square brackets refer to those in the embodiment described later.

[Effect]

When the washer liquid is pumped from the washer tank pump, an upward force is applied to the lids 12 and 22 due to the hydraulic pressure, and the tubes 15 and 25 are able to be displaced upward, so that they are opened. Injection is performed with the nozzle bodies 13 and 23 facing. When spraying of the washer fluid is finished, the lids 12, 22 are automatically closed due to the decrease in the fluid pressure.

[Example of idea]

1 to 3 show a retractable washer nozzle 10 according to an embodiment of the present invention, which is provided in a rectangular notch 1a formed in a hood panel 1 near a windshield 3.

That is, as shown in FIG.
, a lid 12 with a notch 1a whose rear end is hinged to the edge of the case 11, a nozzle body 13 formed inside the back surface of the lid, and a rear end and the case 1.
1 and a vinyl tube 15 formed into a coil shape interposed between the pipe 2 and the bottom of the tube 1.

Attached to the tip of the nozzle body 13 is a cap 13a (FIG. 2a) in which a horizontally elongated groove communicating with the cap 13a is cut out, and a cap 13b (FIG. 2a) formed with two left and right injection ports 13c communicating with the groove. ing.
The coiled tube 15 is tightly wound in multiple layers when the lid 12 is closed during non-operation. The case 11 has a drain hole 11.
a is formed.

During cleaning, the washer fluid is pumped from the tank pump (not shown) through the pipe 2, which applies an upward force to the lid 12 to open it (Fig. 2), and the wiper sweep range is shown in Fig. 3. Inject toward the best position A, about 150 mm below the top of the At this time, the lid 12 acts as a pressure receiving surface for the wind pressure generated when the vehicle is running, and as a result, the elevation of the nozzle body 13 relative to the windshield 3 tends to decrease depending on the vehicle speed. However, the lid 12,
By appropriately setting the weight of the tube 15, the hinge spring force, etc., this elevation can be reduced to positions B and C in Fig. 3, but due to changes in the air flow in front of the windshield 3 according to the vehicle speed, the injection The washer fluid transmitted through the windshield is corrected to the vicinity of the best position A.

When the pressure feeding of the washer liquid is completed, the lid 12 returns to the closed position due to its own weight and the compressive force of the coiled tube 15. Leaking washer liquid or intruding water is drained from the drain hole 11a.

FIG. 4 shows another embodiment of the present invention, in which the lid 23 is integrally formed with the nozzle body 23, the case 21 and the integral hinge 22a, and the upwardly displacing tube is formed as a bellows 25.

[Effect of idea]

As described above, according to the present invention, a retractable washer nozzle that does not require a separate driving source is realized, which does not impair the aesthetic appearance of the hood surface and is effective in preventing the nozzle from clogging with wax, dirt, etc.
