Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in the mounting structure of a vehicle lamp cleaner.

In general, as a vehicle lamp cleaner, for example, as shown in FIG. 1, a headlamp cleaner 4 is installed on the top surface of the front bumper 3 of a vehicle 1 and is designed to wash off dirt from the headlamp 2 with a strong spray.
It has been known.

Conventionally, this type of headlamp cleaner 4, as shown in FIG. It consists of a nozzle part 7 provided therein, and a cylindrical attachment part 8 protruding from the lower part of the cleaner main body part 5. The mounting portion 8 is composed of a mounting base portion 10 that approximately fits into a mounting hole 9 formed in the bumper skin 3a, and an extension portion 11 that protrudes toward the back side of the bumper skin 3a. has a horizontal flange 12
is provided. In this example, the flow path 6 is formed within the mounting portion 8, and one end of a supply hose 13 extending to a wash tank (not shown) in which cleaning liquid is stored is connected to the lower end of the extension portion 11.

Conventionally, when attaching the headlamp cleaner 4 having the above structure to the upper surface of the bumper skin 3a, first, the mounting portion 8 at the lower part of the cleaner main body 5 is inserted into the mounting hole 9 formed in the bumper skin 3a, and then The lower surface of the cleaner body 5 is brought into contact with the upper surface. Next, the back surface 14 of the bumper skin 3a,
As shown in FIG. 3, a retaining clip 15 having bifurcated legs 16, 16 is horizontally fitted into the gap formed between the retaining clip 12 and the flange 12 provided on the mounting portion 8.
By bringing the peaks 17 and 18 at the front and rear ends of the retaining clip 5 into elastic contact with the back surface 14 of the bumper skin 3a, and by bringing the trough 19 at the center of the retaining clip 15 into elastic contact with the flange 12, the cleaner body 5 is attached to the bumper skin 3a. It was fixed by pressing on the top surface (see Utility Model Application Publication No. 55-91748).

However, in the conventional mounting structure in which the retaining clip 15 is fixed by the elastic force of the retaining clip 15 via the mounting portion 8 provided at the lower part of the cleaner main body 5, it is difficult to prevent the cleaner main body 5 from being exposed to strong rotational force, for example. In such a case, the cleaner main body 5 may rotate against the elastic force of the retaining clip 15, or even if there is a rotation prevention structure between the mounting hole 9 and the mounting base 10, the above conventional example may In the case where the bumper skin 3a is made of a resin material as in the case shown in FIG. As a result, the jetting surface 5a of the cleaner main body 5 is oriented laterally with respect to the headlamp, resulting in a problem that a desired cleaning effect cannot be obtained when the headlamp cleaner 4 is used.

Further, when the bumper skin 3a is made of a resin material as in the conventional example, the bumper skin 3a itself is easily deformed at the elastic contact point of the retaining clip 15, and the spring effect of the retaining clip 15 is weakened. This causes problems such as the supporting force is weakened and the cleaner body 5 easily rotates due to vibrations of the vehicle body, or the retaining clip 15 falls off and the cleaner body 5 floats up. Ta.

The present invention has been made in view of the above-mentioned conventional problems, and its purpose is to provide a mounting structure for a vehicle lamp cleaner that can reliably prevent rotation and lifting of the cleaner body. There is a particular thing. The gist of the present invention is to provide a mounting hole for the lamp cleaner in a vehicle bumper, fit a mounting portion protruding from the lower part of the cleaner body into the mounting hole, and insert the mounting portion protruding from the lower part of the cleaner body into the mounting hole. In a vehicle lamp cleaner mounting structure in which a lamp cleaner is fixed to a bumper by fitting a spring member into the gap formed between the flange of the protruding mounting part and the rear surface of the bumper, the bumper has a mounting hole. A positioning hole is provided in a proximate portion, and a positioning protrusion whose tip protrudes from the back side of the bumper is provided at the lower part of the cleaner body corresponding to the positioning hole, and the rear end of the spring member is brought into contact with this positioning protrusion. It's because I was exposed to it.

The present invention will be described in detail below based on embodiments shown in the accompanying drawings.

In the first embodiment of the present invention shown in FIG.
In addition to a mounting portion 8 protruding from the mounting portion 8 having the same structure as the conventional one, a positioning protrusion 21 is integrally molded at a portion adjacent to the mounting portion 8. In addition, the bumper skin 3a has the above-mentioned mounting portion 8.
In addition to a mounting hole 9 into which the holder is fitted, as in the conventional case, a positioning hole 22 into which the positioning projection 21 is fitted is provided at a portion corresponding to the positioning projection 21. The positioning protrusion 21 has a height such that its tip protrudes toward the back side of the bumper skin 3a when it is fitted into the positioning hole 22, and the retaining clip 15 has the same shape as the conventional one. The rear end vertical surface 23 of the retaining clip 15 is provided at a portion where it comes into contact with the positioning protrusion 21 when the retaining clip 15 is attached. Incidentally, the same members as in the prior art are given the same reference numerals and detailed explanations will be omitted.

Therefore, in this embodiment, the mounting portion 8 of the headlamp cleaner 4 is inserted into the mounting hole 9 of the bumper skin 3a and the positioning hole 2 is simultaneously inserted as in the conventional case.
A positioning protrusion 21 is fitted into the inside of the cleaner body 2, and the positioning protrusion 21 and the mounting base 10 fitted into the mounting hole 9 are positioned with respect to the bumper skin 3a, thereby ensuring the rotation of the cleaner main body 20. To prevent. Further, a retaining clip 15 is fitted into the gap between the back surface 14 of the bumper skin 3a and the flange 12 formed on the extension part 11 of the mounting part 8 from the positioning protrusion 21 side.
Retaining clip 1 that comes into elastic contact with the back surface 14 of a
5 peaks 17 and 18 at the front and rear ends, and a trough 1 at the center of the retaining clip 15 that comes into elastic contact with the flange 12
9 pushes them outward from each other, and as a result, the cleaner body 20 is pressed and fixed against the upper surface of the bumper skin 3a. Also, when attaching the retaining clip 15, the rear end vertical surface 23
comes into contact with the positioning protrusion 21, and backward movement is restricted.

Therefore, according to the embodiment described above, since the cleaner main body 20 is positioned at two locations with respect to the bumper skin 3a, its rotational movement is restrained against external forces.
Also, the rear end vertical surface 23 of the retaining clip 15
Since the retaining clip 15 is in contact with the positioning protrusion 21, the contact portion on the back side of the bumper skin 3a with which the retaining clip 15 comes into elastic contact is deformed by the pressing force of the retaining clip 15, and the spring supporting force of the retaining clip 15 is reduced. Even in such a case, the retaining clip 15 has never fallen off, and as a result, the cleaner main body 20 has never been raised above the upper surface of the bumper skin 3a.

FIG. 5 shows a second embodiment of the present invention, which is different from the previous embodiment except that the positioning protrusion 21 and the flange 12 are provided with slopes 24 and 25, respectively, which are inclined toward the insertion direction of the retaining clip 15. Consists of the same configuration as the example.

Therefore, in this embodiment, the headlamp cleaner 4 can be securely fixed as in the previous embodiment, and in addition, when the retaining clip 15 is fitted, it slides on the slopes 24 and 25. Mountain portion 17,1 of retaining clip 15
Since the sliding resistance of the retaining clip 8 and the valley portion 19 can be reduced, the retaining clip 15 can be easily attached.

6 and 7 show a third embodiment of the present invention, in which an extension surface 27 consisting of a horizontal surface and a vertical surface is provided at the lower end of the rear end vertical surface 23 of the retaining clip 26. be. Therefore, when attaching and detaching the retaining clip 26, by pushing down the extension surface 27, the rear crest 18 of the retaining clip 26 is pulled down and can easily get over the positioning protrusion 21, making the attaching and detaching work easier. becomes.

Incidentally, in the above embodiment, an example of a headlamp cleaner has been described, but it goes without saying that the present invention can also be applied to cleaners for other vehicle lamps.

As explained above, according to the mounting structure of the vehicle lamp cleaner according to the present invention, since rotation and lifting of the cleaner main body can be reliably prevented, a predetermined cleaning effect can be obtained for the lamp, and the lamp surface You can reliably wash away dirt.
