Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a structure for mounting a headlamp cleaner to a vehicle bumper.
[0002]
[Prior art]
As shown in FIG. 4, the headlamp cleaner attached to the opening hole of the bumper of the vehicle is fixed to the actuator 1, the nozzle 1 that injects the cleaning liquid, the actuator 2 that pressurizes and supplies the cleaning liquid to the nozzle 1, and the actuator 2. The bracket 3 has a pair of abutting portions 3a that are positioned 180 degrees symmetrical with respect to the axis of the nozzle 1. Then, as shown in FIG. 5, after positioning grommet 5 having four leg portions 5 a from the front side of bumper 4 is fitted into opening hole 4 a of bumper 4, bumper 4 is arranged as shown in FIG. 6. By fitting the bracket 3 to the leg portion 5a of the grommet 5 protruding from the back side of the grommet 5 and pushing it in until the pair of contact portions 3a abut against the back surface of the bumper 4, the head lamp cleaner is moved to the nozzle 1 It was attached to the opening 4a of the bumper 4 while being centered, that is, positioned.
[0003]
[Problems to be solved by the invention]
However, in the case of the conventional example, since a positioning grommet is required, there is a problem that the number of parts is large and the cost is high. Further, since the two parts of the bracket 3 and the grommet 5 affect the centering of the nozzle 1, there is a problem that centering, that is, positioning accuracy is difficult to be obtained. Further, since the work for mounting the headlamp cleaner to the bumper 4 has to be performed from both the front and back sides of the bumper 4, the workability is also poor.
[0004]
Accordingly, the present invention provides a structure for mounting a headlamp cleaner on a vehicle bumper that reduces the number of parts, reduces costs, improves centering, that is, positioning accuracy, and greatly improves workability during mounting. The purpose is to do.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, a headlamp cleaner mounting structure according to the first aspect of the present invention includes a nozzle that injects cleaning liquid, an actuator that pressurizes and supplies the cleaning liquid to the nozzle, and is fixed to the actuator. A pair of claw pieces that are 180 degrees symmetrical with respect to the nozzle axis, and the axis of the nozzle at a position rotated from the claw pieces about the axis of the nozzle by 90 degrees. A pair of abutting pieces that are 180 degrees symmetrical with respect to the heart, and the pair of claw pieces and the pair of abutting pieces are flexible so that both of the claw pieces are bent inward . A claw is formed at the tip, and a contact portion is formed in the vicinity of the tip of the contact piece, and the axial distance between the claw and the contact portion in the axial direction of the nozzle is equal to or slightly smaller than the thickness of the bumper. It has become smaller in, before The vicinity of the tip end portions of the pair of claw pieces and the tip end portions of the pair of contact pieces are pressed against the inner edge of the opening hole of the bumper, and the claw engages with the inner edge portion of the opening hole of the bumper from the surface. The nozzle is automatically positioned when the contact portion comes into contact with the inner edge portion of the opening hole of the bumper from the back side.
[0006]
According to the above structure, since the positioning grommet is not required, the number of parts is reduced and the cost is reduced. In addition, since only the bracket affects the nozzle centering, the centering, that is, the positioning accuracy is easily obtained. In addition, the headlamp cleaner can be attached to the bumper only on the back side of the bumper, improving workability.
[0007]
In order to achieve the above object, the invention according to claim 2 is characterized in that, in claim 1, the bracket has a rectangular cross section substantially coinciding with the rectangular opening hole of the bumper. Is.
[0008]
According to this structure, the rotation of the headlamp cleaner around the nozzle axis is reliably prevented.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail based on an embodiment shown in the drawings.
FIG. 1 is a perspective view showing a mounting structure of a headlamp cleaner according to the present invention. The headlamp cleaner according to the present invention includes a nozzle 11 that injects a cleaning liquid, an actuator 12 that pressurizes and supplies the cleaning liquid to the nozzle 11, and a bracket 13 that is fixed to the actuator 2.
The bracket 13 has a rectangular cross section that substantially coincides with the rectangular opening hole 4 a of the bumper 4, and a pair of flexible claw pieces 13 a that are 180 degrees symmetrical with respect to the axis of the nozzle 11. And a pair of flexible contact pieces 13b that are symmetric with respect to the axis of the nozzle 11 at a position rotated 90 degrees around the axis of the nozzle 11 from the claw piece 13a. ing. A claw 13a 'is formed at the tip of the claw piece 13a, and a contact portion 13b' is formed near the tip of the contact piece 13b. Note that the distance between the claw 13a ′ and the contact portion 13b ′ in the axial direction of the nozzle 11 is equal to or slightly smaller than the thickness of the bumper 4.
[0010]
Next, a procedure for attaching the headlamp cleaner to the bumper will be described below.
First, as shown in FIGS. 2A and 2B, the pair of claws 13a of the bracket 13 are bent inward with fingers, inserted into the opening 4a from the back side of the bumper 4, and then the fingers are released. Due to the force to return the claw piece 13a to the original, that is, the reaction force, the vicinity of the tip of the claw piece 13a is pressed against the inner edge of the opening hole 4a, and the claw 13a 'is engaged with the inner edge of the opening hole 4a from the front side .
[0011]
Next, as shown in FIGS. 3A and 3B, when the pair of contact pieces 13 b of the bracket 13 are bent inward with fingers, the tips of the contact pieces 13 b are moved on the back surface of the bumper 4. Slip into the opening hole 4a. Thereafter, when the finger is released, the tip of the contact piece 13a comes into pressure contact with the inner edge of the opening hole 4a by the force of returning to the original position of the contact piece 13, that is, the reaction force, and the contact part 13b 'is the inner edge of the opening hole 4a. Abuts against the part from the back side. Thus, the vicinity of the tip of the pair of claw pieces 13 and the tip of the pair of contact pieces 13b are pressed against the inner edge of the opening hole 4a, and the claw 13a 'is engaged with the inner edge of the opening hole 4a from the front side. When the abutting portion 13b ′ abuts against the inner edge of the opening hole 4a from the back side, the head lamp cleaner is attached to the bumper 4 without backlash while the nozzle 11 is centered, that is, positioned automatically.
[0012]
According to this structure, since the positioning grommet is not required, the number of parts is reduced and the cost is reduced. In addition, since only the bracket 13 affects the centering of the nozzle 1, centering, that is, positioning accuracy is easily obtained. Furthermore, since the work for attaching the headlamp cleaner to the bumper 4 can be performed only on the back side of the bumper 4, workability is also improved. Further, since the bracket 13 has a rectangular cross section that substantially coincides with the rectangular opening hole 4a of the bumper 4, rotation around the nozzle axis of the headlamp cleaner is reliably prevented.
[0013]
【The invention's effect】
As described above, according to the mounting structure of the headlamp cleaner to the vehicle bumper according to the present invention, the number of parts is reduced, the cost is reduced, the centering, that is, the positioning accuracy is improved, and the workability during mounting is greatly improved. There is an advantage of improving.
