Abstract

PURPOSE:To improve interchangeability for setting part constituent parts, by elastically inserting a plate spring-form clamp member, consisting of an elastic member having a forked structure in the piece part, into a space between a flange-form clamp presser projection and a bumper lower surface. CONSTITUTION:Dimension between an upper piece part 22 and a lower piece part 23 of a plate spring-form clamp member 20 is constituted to be larger than an interval between a clamp presser projection 12 and a lower surface of a bumper (a). When a head lamp cleaner 1 is attached to the clamp member with this, the upper piece part 22 is situated at the lower surface side of the bumper (a) and the lower piece part 23 at the side of the clamp presser projection 12 respectively, whereby the clamp member 20 is pressed in the state that forked structures 24 and 25 sandwich a connecting pipe 5. If so, this connecting pipe 15 is drawn in a lower part of the bumper (a) by dint of elasticity of the clamp member 20, thus a nozzle case 2 is pressed to the top of the bumper (a) and clamped thereto. With this constitution, it is correspondable to setting parts of various headlamp cleaners 1.

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a mounting structure for an automobile headlamp cleaner that spouts washing water for washing the automobile headlamp while the car is running, and particularly relates to a mounting structure for an automobile headlamp cleaner that sprays washing water for washing the automobile headlamp while the car is running. It relates to technology that improves compatibility and improves compatibility.

[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 55 is press-fitted between the clamp holding protrusion 54 formed on the connecting pipe 53 and the lower surface of the bumper a, and the lower surface of the nozzle case 50 is press-bonded to the upper surface of the bumper a via the clamp holding protrusion 54. The following mounting means are used.

[Problem that the invention seeks to solve]

Therefore, the elastic attachment means of the corrugated plate spring clamp 55 is
The elastic properties of the spring determine the workability during installation and the holding force after installation, but with the shape of the corrugated plate spring, the deflection in the plane direction (arrow A) is small, and the distance between the members used to obtain a preferable elastic force is small. Not only does the tolerance range for the corrugated plate spring clamp 55 become smaller during insertion, but also
This has caused problems such as bending and making it impossible to obtain a predetermined elastic holding force.

The present invention was devised in view of the above problem, and includes a plate spring clamp member having a large deflection allowance in the mounting direction, and an automobile headlamp cleaner to be attached to the bumper is placed between a part of the cleaner and the lower surface of the bumper. It is an object of the present invention to provide a mounting structure for an automobile headlamp cleaner that has a large clearance for elastically inserting a plate spring clamp member when it is elastically inserted.

[Means for solving problems]

In the mounting structure of the automotive headlamp cleaner according to the present invention, a nozzle holder having a cleaning water injection nozzle on the top protrudes from the lower end of the nozzle case, and the lower surface of the nozzle case abuts a part of the mounting part on the vehicle side. , in an automobile headlamp cleaner in which a cylindrical shaft part continuous with the nozzle holder is fixed by protruding to the lower surface side, the cylindrical shaft part is elastically inserted between a flange-like clamp holding protrusion formed on a part of the cylindrical shaft part and the lower surface of the bumper. The gist is a special shape of the plate-shaped strip-shaped clamp member, which is made of an elastic material having an appropriate elastic force, and whose side surface shape is approximately "U" or "U" bent sideways. A bifurcated structure is formed on the upper and lower pieces curved in a character shape, respectively, to straddle the nozzle holder or the cylindrical shaft portion continuous with the nozzle holder.

Further, the lower piece of the plate-shaped clamp member has an introduction guide portion bent and inclined toward the upper piece at its tip.

[Effect]

According to the above configuration, the connecting pipe is inserted into the through hole from the top surface of the bumper, and with the bottom surface of the nozzle case in contact with the top surface of the bumper, the top piece is placed on the bottom side of the bumper, and the top piece is placed on the side of the clamp presser protrusion. By press-fitting the plate-like strip-like clamp member so that the lower piece is positioned and with the two forked structures sandwiching the connecting pipe, the elasticity of the plate-like strip-like clamp member allows the connecting pipe to be inserted through the brim-like projection. is pulled under the bumper, and its elastic tensile force firmly presses and fixes the nozzle case to the top surface of the bumper. Further, when the plate-shaped clamp member is press-fitted, the inclined introduction guide portion is inserted into the upper surface side of the clamp presser protrusion, so that it is possible to grope at the time of assembly.
