Description

[Detailed Description of the Invention] The present invention relates to an improvement in the mounting structure of a vehicle wash nozzle.

The conventional washing nozzle mounting structure is as follows:
For example, as shown in FIG. 1, the washer nozzle 1 is formed into a predetermined shape using a circular brass tube, and the vicinity of the base end 2 of the washer nozzle 1 is made to protrude in the radial direction to form the flange 3. , a nozzle insertion hole 6 is bored in the vertical wall 5 of the cowl top 4, and the washer nozzle 1 is inserted into the nozzle insertion hole 6 from its tip, and the collar 3 is inserted outside the vertical wall 5 of the cowl top 4. The washer nozzle is brought into contact with the surface and housed in a cowl box 8 formed by the wash nozzle 1, the cowl top 4, and the dash upper panel 7, and the flange 3 is fixed to the vertical wall portion 5 of the cowl top 4. There is one with 1 installed. In addition, in Figure 1, 9 is the window glass, 10 is the cowl top grill,
11 is a slit for introducing outside air opened in the cowl top grill 10, 12 is an outside air inlet opened on the top surface of the cowl top 4, and 13 is a washer nozzle 1.
This is a tube that connects the water tank to a wash tank (not shown).

As shown in FIGS. 2 and 3, another conventional mounting structure for the washer nozzle is such that the washer nozzle 1 is integrally attached to a ball-shaped rotating body 14, and the tip of the washer nozzle 1 is attached to the rotating body 14. The rotating body 14 is rotatably pivotally mounted within the casing 15, and the tip of the washer nozzle 1 is formed to protrude from the opening 16 of the casing 15. The casing 15 is arranged on the upper surface of the hood panel 18 by inserting a clip 17 attached to the lower surface of the casing 15 into a through hole formed in the hood panel 18. In some cases, the angle of inclination of the washer nozzle 1 with respect to the front window glass 9 is adjusted by pinching and operating the tip of the washer nozzle 1.

However, in the conventional example shown in FIG. 1, the washer nozzle 1 is fixed in advance to the vertical wall 5 of the cowl top 4, and the washer nozzle 1 is formed to spray the cleaning liquid toward the window glass 9 in a predetermined direction. However, if it is necessary to adjust the injection position of the cleaning liquid from the wash nozzle 1, the tip of the wash nozzle 1 is plastically deformed using a tool, etc., so that the ejection port of the wash nozzle 1 is directed in a predetermined direction. The operation had to be performed, and the operation was extremely troublesome. Furthermore, even if the tip of the washer nozzle 1 is plastically deformed using a tool or the like, when the tool or the like is removed, the deformation state of the tip of the washer nozzle 1 will change slightly due to its elasticity. , it became difficult to finely adjust the tip of the washer nozzle 1, and there was a fear that it would be difficult to accurately adjust the injection position of the cleaning liquid from the washer nozzle 1.

In addition, in the conventional example shown in FIGS. 2 and 3, when adjusting the injection position of the cleaning liquid from the washer nozzle 1, the washer nozzle 1 is adjusted in a predetermined direction to position the washer nozzle 1. Not only does this operation become troublesome, but also because the tip of the washer nozzle 1 protrudes above the top surface of the hood panel 18, when applying wax or the like to the hood panel 18, etc. Wax etc. clog the tip spout, and as a result, the washer nozzle 1
There was also a risk that a situation would arise in which the cleaning liquid could not be sprayed from the pipe.

The present invention was developed based on the above-mentioned viewpoints, and its purpose is to make it possible to very easily and accurately adjust the injection position of the cleaning liquid from the wash nozzle, and to make it possible to adjust the injection position of the wash liquid from the wash nozzle during waxing work. To provide a mounting structure for a vehicle washer nozzle that can completely prevent clogging with wax or the like.

The gist of the present invention is that a sliding guide having a pair of left and right guide grooves is provided integrally with the washer nozzle, and that the sliding guide has a cut groove parallel to the guide groove and a cut groove directed upward from the guide groove. On the other hand, a pair of left and right guide rails extending in the longitudinal direction of the vehicle body is provided in the cowl top grille or the outside air introduction part of the cowl top, and the tapered surface of the sliding guide is formed on this guide rail. A mounting structure for a vehicle washer nozzle, wherein the guide rail and the guide groove are fitted by being inserted while making elastic contact with each other, and the washer nozzle is arranged at an arbitrary position along the guide rail below the upper surface of the cowl top grill. be.

Hereinafter, the present invention will be described in detail based on embodiments shown in the accompanying drawings.

In the first embodiment shown in FIGS. 4 to 6,
While the wash nozzle 1 and the sliding guide 20 are integrally molded from resin or the like, the cowl top grill 10

It was installed on.

In this embodiment, as shown in FIGS. 4 and 6, the washer nozzle 1 is formed with a sliding guide 20 inclined. This sliding guide 20 has a substantially U-shaped cut groove 23 in the longitudinal direction.
A pair of legs 24 are provided opposite each other with the cut groove 23 in between, and the outer surface of the legs 24 is shaped such that the center thereof bulges outward. The leg portion 24 is formed into a tapered surface 25 from the tip to the center thereof. Furthermore, a guide groove 26 extending in the longitudinal direction of the sliding guide 20 is recessed approximately at the center of the outer surface of the leg portion 24 . Note that the tip of the washer nozzle 1 is
As shown in the figure, the guide groove 26 of the sliding guide 20
It is located in the direction of extension of .

On the other hand, as shown in FIGS. 4 and 6, the cowl top grille 10 is provided with a plurality of slits 11 extending in the front-rear direction of the vehicle body as outside air introduction portions. A protruding flange 27 is provided, and the tips of the flanges 27 are bent inward to form a guide rail 21 extending in the longitudinal direction of the vehicle body. The width of the slit 11 is formed to substantially match the maximum width of the sliding guide 21, that is, the width at the substantially central portion of the leg portion 24, and the width of the slit 11 is formed to substantially match the maximum width of the sliding guide 21, that is, the width at the substantially central portion of the leg portion 24. The depth is formed to approximately correspond to the depth of the inward cut of the guide groove 26 of the sliding guide 20.

Therefore, when installing the wash nozzle 1 equipped with the sliding guide 20 on the guide rail 21 formed on the cowl top grill 10, the wash nozzle 1 should be mounted below the cowl top grill 10 so that the tip of the wash nozzle 1 faces the window glass. The sliding guide 20 is brought closer toward the slit 11 of the cowl top grill 10, and the sliding guide 20 is fitted into the slit 11 so that the guide rail 21 is fitted into the guide groove 26 of the sliding guide 20. do it. In this case, first, the legs 24 of the sliding guide 20
When the tapered surface 25 of the leg 24 contacts the side edge of the guide rail 21 and the sliding guide 20 is further pushed upward, the tapered surface 25 of the leg 24 and the guide rail 2
1, each leg 24 is elastically deformed inward due to the cut groove 23 interposed therebetween, and is then formed approximately at the center of the outer surface of the leg 24. When the guide rail 21 is fitted into the guide groove 26, the leg portion 24, which had been elastically deformed inward, returns to its original shape, and the upper and lower surfaces of the guide groove 26 sandwich the guide rail 21. become.

As a result, the sliding guide 20 is slidably locked along the guide rail 21 without rattling, and the washer nozzle 1 is attached to the guide rail 21 via the sliding guide 20.

In this state, the wash nozzle 1 is housed below the upper surface 28 of the cowl top grille 10, and when adjusting the injection position of the washing liquid from the wash nozzle 1, the slide located above the guide rail 21 is used. Dynamic guide 20
This is done by grasping the legs 24 of the slide guide 20 and moving the sliding guide 20 along the guide rail 21 to set the washer nozzle 1 at a predetermined position. At this time, the mounting posture of the washer nozzle 1 with respect to the guide rail 21 is always kept constant, and the direction of jetting the cleaning liquid from the washer nozzle 1 is constant, but the relative positional relationship between the washer nozzle 1 and the window glass (not shown) As a result, the injection position of the cleaning liquid onto the window glass can be accurately adjusted depending on the position of the washer nozzle 1 on the guide rail 21.

In the above embodiment, the guide rail 21
are formed at the lower part of the flanges 27 formed on the left and right edges of the slit 11 of the cowl top grille 10, but it is not necessarily necessary to provide the flanges 27 on the left and right edges of the slit 11. Guide rail 21 with the edge intact
It may be used as

Next, a second embodiment shown in FIG. 7 will be described.

In this embodiment, unlike the first embodiment, a guide rail 21 is provided on the outside air inlet 12 as an outside air introduction section drilled in the upper surface of the cowl top 4, and this guide rail 21 is formed by installing a pair of metal plates in the front-rear direction of the vehicle body on the outside air inlet 12. As in the first embodiment, the sliding guide 20 and the washer nozzle 1 are integrally formed, and the guide rail 21 is fitted into the guide groove 26 of the sliding guide 20 to attach the washer nozzle 1. Incidentally, in this embodiment as well, when the washer nozzle 1 is attached to the guide rail 21 via the sliding guide 20, the washer nozzle 1 will contact the upper surface 2 of the cowl top grille 10.
It is stored below 8.

Therefore, according to the mounting structure for a vehicle wash nozzle according to the present invention, the wash nozzle and the sliding guide are integrally molded with resin or the like, and the sliding guide is slidably engaged with a guide rail extending in the longitudinal direction of the vehicle body. Since the washer nozzle is arranged at an arbitrary position along the guide rail, the spraying position of the cleaning liquid from the washer nozzle can be adjusted simply by appropriately moving the washer nozzle along the guide rail. Therefore, when adjusting the injection position, the troublesome work of plastically deforming the tip of the wash nozzle or rotating the wash nozzle to change the direction of the wash nozzle, as in the past, is no longer necessary, and the injection position can be adjusted accordingly. Not only does the position adjustment work become extremely easy, but since the mounting position of the washer nozzle is kept constant, the direction in which the washer nozzle sprays the cleaning liquid is constant, and accordingly, the spraying position can be adjusted accurately. can.

Furthermore, as shown in the above embodiment, the washer nozzle is stored below the upper surface of the cowl top grill, which eliminates the problem of wax clogging the nozzle outlet during waxing work, making it impossible to spray cleaning fluid.

Furthermore, as shown in the first embodiment, if the outside air introduction part of the cowl top grill is used as it is as a guide rail, there is no need to provide a separate guide rail, and the number of parts can be reduced. You can also do it.
