Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to an installation technique for an automobile headlamp cleaner that spouts cleaning water for cleaning the automobile headlamp while the car is running, and in particular, The present invention relates to a headlamp cleaner for an automobile in which mounting holes can be easily drilled and the direction of jetting cleaning water can be easily adjusted.

[Conventional technology]

Conventionally, as shown in FIG. 4, a cleaning water injection nozzle installed at the top of a nozzle case 50 has been used as a headlamp cleaner to clean dirt, insects, etc. adhering to the headlamp of an automobile while the headlamp is running and restore the light emitting performance. A cleaning device is used that sprays high-pressure cleaning water from 51 toward the headlamp, and this type of device has a mounting structure in which the nozzle case 50 is fixed to the upper surface of the bumper a in front of the headlamp, and the nozzle case 50 protrudes from the bottom side. A corrugated plate spring clamp 54 is press-inserted between the lower surface of the bumper a and the clamp retaining protrusion 53 formed at the boundary with the connecting pipe 52, and the lower surface of the nozzle case 50 is attached to the upper surface of the bumper a via the clamp retaining protrusion 53. Attachment means by pressure bonding are used.

[Problem that the invention attempts to solve]

However, conventionally, for the purpose of determining the insertion direction of the corrugated spring clamp 54, a guide parallel surface portion 55 is formed at the bumper a mounting position of the nozzle case 50.
Since the planar shape of the part is oval or oval, it is necessary to drill a non-circular attachment hole 56 such as an oval or oval in the bumper a of the attached part, which is not only difficult to process. After drilling the mounting hole 56, it also serves as a rotation stopper for the headlamp cleaner.
There are problems such as the need to drill the mounting hole 56 in an accurate direction.

The present invention has been devised in view of the above-mentioned problems, and an object of the present invention is to provide a headlamp cleaner for an automobile that facilitates the machining of the mounting hole and allows the rotational position to be adjusted after installation.

[Means for solving problems]

The automotive headlamp cleaner mounting clamp according to the present invention has a connecting pipe protruding from the lower end of the nozzle case which has a cleaning water injection nozzle at the top, and
abutting the periphery of the nozzle case against a part of the vehicle-side mounting portion, and protruding the nozzle case toward the lower surface thereof;
When installing an automobile headlamp cleaner in which a plate-shaped clamp member is elastically inserted between the clamping protrusion formed on a part of the nozzle case and the lower surface of the mounting surface, the headlamp cleaner for an automobile is installed, parallel to the outer periphery of the nozzle case near the clamping protrusion. A bifurcated structure that straddles the nozzle case is formed in an upper piece part and a lower piece part, each of which has a side surface shape approximately like a "U" shape or a sideways "U" shape with respect to the parallel surface part. The gist is that the two-pronged structure of the lower piece of the plate-shaped clamp member is elastically inserted so as to be freely inserted and removed from the side and to prevent rotation.

That is, the head lamp cleaner for an automobile according to the present invention has a connecting pipe protruding from the lower end of a nozzle case provided with a cleaning water injection nozzle at the top, and the periphery of the nozzle case is brought into contact with a part of the mounting part on the automobile side. A head lamp cleaner for an automobile in which a nozzle case protrudes toward the lower surface side and a plate-shaped clamp member is elastically inserted between a clamp holding protrusion formed on a part of the nozzle case and a mounting lower surface to fix it. A parallel surface portion is formed on the outer periphery of the nozzle case of the strip-shaped clamp member insertion portion, and the plate-shaped strip-shaped clamp member is made of an elastic material having an appropriate elastic force so that the side surface shape is approximately “U” or “U” when turned sideways.
The lower piece has a two-pronged structure formed by bending it into a letter shape, and has a two-pronged structure formed on the curved upper and lower pieces, respectively, so as to straddle the parallel surface portion of the nozzle case in a direction parallel to the parallel surface portion. The fork width is such that it can be inserted and removed only from the inside.

[Effect]

According to the above configuration, the connecting pipe is inserted into the through hole from the top surface of the vehicle side mounting part of the bumper, etc., and the upper piece is attached to the bottom surface of the bumper while the periphery of the nozzle case is in contact with the top surface of the bumper. By press-fitting the plate-shaped strip-shaped clamp member so that the lower piece is located on the presser protrusion side and with the two-pronged structure sandwiching the nozzle case, the elasticity of the plate-shaped strip-shaped clamp member to expand in the vertical direction is increased. The force causes the nozzle case to be drawn below the bumper via the clamp holding protrusion, and its elastic tensile force strongly presses the periphery against the top surface of the bumper, thereby fixing the nozzle case.

However, the anti-rotation action between the nozzle case and the plate-shaped clamp member is achieved by the engagement between the two-pronged structure on the lower side of the plate-shaped clamp member and the parallel surface portion of the nozzle case. The outer periphery of the nozzle case near the insertion installation surface with the bumper into which one side is inserted can be kept circular. Therefore, the mounting hole drilled in the vehicle body on the mounting side, such as a bumper, for inserting the nozzle case can be simply a perfect circular hole, which simplifies the machining of the mounting hole.

〔Example〕

Hereinafter, one embodiment of the automotive headlamp cleaner according to the present invention will be described with reference to the drawings.
Figures 3 to 3 show a bumper-embedded headlamp cleaner for an automobile.

In the drawings, reference numeral 1 denotes a nozzle case made of a suitable material such as synthetic resin or rubber, and a spherical base 4 of a cleaning water injection nozzle 3 is mounted on the top of an outer cylinder 2 of the nozzle case 1 in an airtight manner and capable of rotational displacement adjustment. While forming a substantially hemispherical fitting recess 5 that fits into the
A connecting pipe 6 is provided diagonally protruding from the bottom surface of the fitting recess 5 and communicates with a through hole formed in the bottom surface of the fitting recess 5 . Further, a peripheral edge 7 is provided protrudingly on the outer periphery of the top of the outer cylinder 2, and a flange-shaped clamp presser projection 9 is bored in the small diameter portion 8 at the lower end. A parallel surface portion 10 for inserting the plate-shaped clamp member 12 is formed, and a convex rib 11 is provided on the upper surface side of the clamp presser projection 9 in a direction perpendicular to the parallel surface portion 10.

The plate-shaped clamp member 12 includes a bumper a
The bullet is inserted from the upper surface side of a perfectly circular mounting hole b drilled at the mounting position of the bumper a, and the peripheral edge 7 is engaged with the upper surface side of the bumper a, and the bullet is inserted between the lower surface of the bumper a and the clamp holding protrusion 12. It is something to do. That is, the plate-shaped strip-shaped clamp member 12 is made of an elastic material such as spring steel, and is bent through a bent portion 13 so that the side surface shape is approximately a "U" shape or a tilted "U" shape. 1
4 and a lower piece part 15, the natural width between the two pieces 14 and 15 is configured to be larger than the distance between the clamp holding protrusion 9 and the lower surface of the bumper a, and the upper piece is elastically biased in the vertical direction. A bifurcated structure 16 is formed in the portion 14 and extends over the outer cylinder 2 of the nozzle case 1.
A bifurcated structure 17 having a fork width that straddles the parallel surface portion 10 of the small diameter portion 8 and has a rotation preventing function is constructed. Furthermore, a recessed line 18 extending in the width direction is formed on the lower surface of the lower midsection of the lower piece part 15, and the recessed line 18 is formed at a position where the plate-shaped clamp member 12 is completely inserted between the clamp holding projection 9 and the lower surface of the bumper a. is the clamp presser protrusion 9
The guide portion 19 is configured to engage with the convex rib 11 in a moderate manner, and the tip end side of the grooved line 18 forms an introduction guide portion 19 bent and inclined in the direction of the upper piece portion 15.

The headlamp cleaner with the above configuration is installed on the bumper a.
When installing the outer cylinder 2 into the bumper a, make a perfect circular mounting hole b into which the outer cylinder 2 is inserted, insert it from the connecting pipe 4 direction so that the peripheral edge 7 is in close contact with the upper surface of the bumper a, and use a clamp holder. Protrusion 9 and bumper a
The clamp member 12 is press-fitted between the lower surfaces of the two-pronged structure 16 and 17. Due to this insertion, the clamp holding protrusion 9 pushes up the lower piece 15 along the introduction guide part 19, and the nozzle case 1 is pushed downward via the clamp holding protrusion 9 due to the elastic force accompanying the deflection of the plate-shaped clamp member 12. The nozzle case 1 is pushed down and the peripheral edge 7 of the nozzle case 1 is elastically pressed onto the upper surface of the bumper a, so that it is fixed by this pressing action.

Therefore, when installing the automotive headlamp cleaner according to the present invention, it is only necessary to drill a perfect circular mounting hole b into which the outer tube 2 is inserted into the bumper, etc. on the side to be installed, which improves work efficiency. It is something that can be improved.

Although the configuration of the above embodiment allows the nozzle case 1 to be rotated and adjusted after being attached to the bumper a, as a structure to prevent this rotation, a plate-like clamping member 12 is placed at a position on the lower surface of the bumper a where it slides. Guide ribs (not shown) that engage with the upper piece 14 can also be formed.

[Effect of idea]

Since the automotive headlamp cleaner according to the present invention is constructed as described above, the plate-shaped strip clamp member and the nozzle case rotation prevention structure are constructed in a part separated from the part to be mounted such as a bumper, so that the mounting hole can be fixed. It is possible to make it into a perfect circle shape, and the workability associated with the drilling process is improved, and the practical effects after implementation of the present invention are extremely large.
