Description

TECHNICAL FIELD The disclosed embodiments relate to a fluid ejection device and a method of attaching a fluid ejection device.

Japanese Patent Application Publication No. 2016-000599

However, the above-mentioned conventional technology has room for further improvement in terms of making it possible to install it at low cost to prevent the generation of abnormal noise.

Specifically, fluid injection devices generally use a motor as a drive source to drive a fluid pump that compresses fluid, but vibrations are generated during driving, and the vibrations are transmitted to the vehicle body and can cause large changes. Sound may be generated.

For this reason, fluid injection devices have conventionally often adopted a mounting structure that damps vibrations transmitted to the vehicle body by interposing an elastic body such as rubber in the engagement portion with the vehicle body. In addition, when adopting such a structure, the elastic body may deteriorate due to impact or change over time, causing the engagement with the vehicle body to become loose. To deal with this, a sleeve is inserted inside the elastic body. , often fixed with screws, etc.

However, such a mounting structure increases the number of parts and tends to be expensive.

One aspect of the embodiment has been made in view of the above, and it is an object of the present invention to provide a fluid ejecting device and a method for attaching the fluid ejecting device that can be installed at low cost to prevent the generation of abnormal noise. purpose.

A fluid ejecting device according to one aspect of the embodiment includes a support fixed to an installation surface and a main body configured to be capable of delivering compressed fluid. The support has a bottom part in which a first hole facing the installation surface is formed, and an upright part erected from the bottom part and in which a second hole is formed. The main body portion has a first convex portion protruding from a side surface of the upright portion, and a second convex portion protruding toward the bottom surface portion, and the first convex portion is formed through a first elastic body. The second convex portion is inserted into the first hole via the second elastic body.

According to one aspect of the embodiment, it can be installed at low cost to prevent abnormal noise from occurring.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a fluid ejecting device and a method of attaching a fluid ejecting device disclosed in the present application will be described in detail with reference to the accompanying drawings. Note that the present invention is not limited to the embodiments described below.

In addition, in order to make the explanation easier to understand, each of the drawings shown below shows a three-dimensional orthogonal coordinate system in which the installation surface of the fluid ejection device is the XY plane, and the vertical direction perpendicular to the XY plane is the Z axis direction. Illustrated as appropriate.

Furthermore, when we say "perpendicular" or "parallel" below, we do not mean strictly perpendicular or parallel geometrically, but include substantially perpendicular or substantially parallel with a tolerance.

First, a comparative example of this embodiment will be explained. FIG. 1 is an explanatory diagram of a fluid ejecting device 10A according to a first comparative example. Further, FIG. 2 is an explanatory diagram of a fluid ejecting device 10B according to a second comparative example. Further, FIG. 3 is a schematic cross-sectional view taken along the line AA shown in FIG.

As shown in FIG. 1, the fluid ejecting device 10A according to the first comparative example includes a main body 11 and a bracket 12. The main body portion 11 has a bottom portion 11a, a fluid pump 11b, and a delivery portion 11c.

The bottom portion 11a is attached to the bracket 12 via a vibration-proof rubber AR. The fluid pump 11b is driven by a motor (not shown) and compresses fluid. The delivery unit 11c sends out the fluid compressed by the fluid pump 11b toward a nozzle, which is an injection port, through a hose (not shown) or the like. The bracket 12 is attached to an installation surface 30 on the vehicle body side formed of sheet metal or the like.

Such a mounting structure in which the vibration isolating rubber AR is interposed is adopted to attenuate the vibrations generated when the fluid pump 11b is driven and transmitted to the vehicle body, thereby preventing the generation of large abnormal noises. Often.

However, the anti-vibration rubber AR deteriorates due to impact and changes over time, and may loosen its engagement with the vehicle body. For this reason, for example, in the fluid ejecting device 10B according to the second comparative example, as shown in FIGS. 2 and 3, the sleeve SL is fitted inside the annular vibration isolating rubber AR, and the screw SW inserted into the sleeve SL It has a mounting structure for fixing the bottom part 11a (that is, the main body part 11) and the bracket 12.

However, such a mounting structure increases the number of parts and tends to be expensive. For example, in the case of the fluid ejecting device 10B shown in FIGS. 2 and 3, it has a three-point support structure in which there are three fixing locations with screws SW, so at least three vibration-proof rubber ARs and three sleeves SL are installed as attachment parts. , 3 screws SW are required. Further, the sleeve SL is often made of expensive brass. That is, the number of parts increases, leading to high costs.

Therefore, the method for attaching the fluid ejecting device 10 according to the embodiment includes the bracket 12 fixed to the installation surface 30 and the main body 11 provided so as to be able to send out compressed fluid. The main body part 11 has a bottom part in which a first hole facing the surface 30 is formed, and a standing part standing up from the bottom part and having a second hole formed therein.

The main body portion 11 has a first convex portion 11d that protrudes in the negative direction of the X-axis on a side surface parallel to the YZ plane. In this embodiment, the first convex portions 11d are provided at two locations in parallel along the Y-axis.

Further, the main body portion 11 has a second convex portion 11e (not shown in the drawings) that protrudes in the negative direction of the Z-axis on the bottom surface side parallel to the XY plane (see FIG. 6 and subsequent figures). The second convex portion 11e is provided at one location.

The bracket 12 has a bottom portion 12a and an upright portion 12b. The bottom portion 12a is provided parallel to the XY plane. The upright portion 12b is connected to the bottom surface portion 12a and is erected perpendicularly to the bottom surface portion 12a along the YZ plane.

It is provided at the apex position of an isosceles triangle whose base is a straight line. It is recommended that the apex position be arranged so that the center of gravity of the fluid ejecting device 10 is the same as the center of gravity of the isosceles triangle. This is because even if an isosceles triangle is formed, the vibration effect will be reduced if the center of gravity of the fluid ejecting device 10 is not located inside the triangle. If it is difficult to arrange them, the through holes 11ea and the holes 12aa are arranged so that the center of gravity of the triangle is as close as possible to the center of gravity of the fluid ejecting device 10.
