Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a mounting device for a liquid level detector incorporating a fuel pump.

[Background of the idea]

As a conventional mounting device for this type of liquid level detector, there is one shown in FIG. 3, for example. This mounting device suspends a plurality of brackets 6 for holding a fuel pump 5 on the lower surface of a top cover 4 that is attached by mounting screws 3 to an opening 2 formed in a top shell 1 of a fuel tank. In addition, these brackets 6 have
A groove 8 having a generally U-shaped side surface is formed, and locking protrusions 7 protruding from four locations on the circumferential surface of the fuel pump 5 are engaged with this groove 8. .

In order to hold this fuel pump 5 on the bracket 6, each protrusion 7 of the fuel pump 5 having the above shape is fitted into each groove 8 of the bracket 6, and then the protrusion 7 and the groove 8 are fitted. A rivet 10 is inserted into a through hole 9 drilled in the hanging direction of the fuel pump 5 and the bracket 6 to integrally connect the fuel pump 5 and the bracket 6. Both brackets 6 are fastened by a band 12 guided by a band guide protrusion 11 formed at the lower end. Note that 13 is the upper lid 1
14 is a connecting tube that connects the discharge pipe 13 with a discharge port 15 provided in the fuel pump 5, and 16 is a liquid level detector 17 held on the outer surface of the bracket 6. This is a float arm with a float 18 attached to its tip.

However, in the case of such a conventional mounting device for a liquid level detector incorporating a built-in fuel pump, a pair of brackets 6 for fixing the liquid level detector 17 and holding the fuel pump 5 are attached to the upper lid 4. Since the bracket 6 is attached to the lower surface in a hanging state, the bracket 6 is fixed to the upper cover 4 before the fuel pump 5 is attached in the manufacturing process of the liquid level detector.
If the fuel pump 5 comes into contact with other objects during transportation, etc., the bracket 6 to which the fuel pump 5 is not attached will be deformed (distorted) due to its low strength. liquid level detector 17 and its float 18
There was a problem in that the reference setting position of the sensor changed, making it impossible to accurately detect the liquid level.

[Purpose of invention]

The present invention was developed by focusing on these conventional problems, and includes reinforcement to suppress deformation (distortion) before the fuel pump 5 is attached to the bracket 6 attached to the lower surface of the upper cover 4. It is an object of the present invention to provide a mounting device for a liquid level detector which can eliminate the conventional drawbacks by integrally providing a mounting ring.

[Example of idea]

The present invention will be explained in detail below based on the embodiment shown in FIG. 1 and FIG. , and the explanation of the same structural parts will be omitted.

That is, the pair of brackets 6, which are attached to the lower surface of the upper lid 4 in a hanging state, have U-shaped side grooves in which projections 7 provided at four locations on the circumferential surface of the fuel pump 5 are engaged, as in the conventional example. 8 is provided, and this groove 8
The fuel pump 5 is held by engaging the protrusion 7 therein, and the grooves 8 of both brackets 6 have grooves 8 in which both brackets 6, 6 are held.
A ring 20 formed of a surrounding metal band is fixed to the bracket 6, for example by welding means.

Therefore, the upper ends of both brackets 6 are connected to the upper lid 4.
Since a ring 20 is fixed to the lower side of the bracket 6, and a ring 20 is integrally attached to the lower part of the bracket 6 to connect both brackets 6, 6, the mounting strength and rigidity of each bracket 6 is increased. As a result, when transporting the bracket 6 in a state before the fuel pump 5 is attached or when attaching the fuel pump to the bracket 6,
The bracket 6 is not deformed (distorted).
Therefore, since there is no positional variation in the liquid level detector 17 attached to the bracket 6, accurate liquid level detection is possible. Also, in bracket 6,
By providing the ring 20 integrally in advance, the work step of attaching the band 12, which is conventionally used, can be omitted, thereby making it possible to reduce the number of parts and work steps, thereby increasing economic efficiency.

[Summary of the invention] As explained above, the present invention has a plurality of brackets 6 hanging down and fixed to the inside of the lid 4 that closes the opening 2 of the fuel tank 1 of an automobile, and A protrusion 7 provided on the circumferential surface of the fuel pump 5 is engaged with the U-shaped side groove 8 to clamp and fix the fuel pump 5, and the bracket 6 has a float 18 floating on the fuel liquid. A liquid level detector 17 that emits a signal at a level corresponding to the displacement of the float 18 is installed, and these brackets 6 are connected to a position closer to the lid 4 than the gripping portion of the fuel pump of the plurality of brackets 6. This is a liquid level detector mounting device characterized in that a ring 20 is fixed.

[Effect of the invention] Therefore, according to this mounting device, the liquid level detector 17
and a plurality of brackets 6 for holding the fuel pump 5.
The upper end of each bracket 6 is fixed to the lid 4, and the bodies of each bracket 6 are integrally connected to each other via a ring 20 before the process of attaching the fuel pump 5, so that the rigidity of each bracket is increased. As a result, deformation of the bracket can be suppressed, so there is no positional error in the liquid level detector attached to the bracket 6, and accurate liquid level detection is possible.
Since the work of attaching the band after attaching the fuel pump as in the conventional example can be omitted, the fuel pump is not damaged during band attaching, and there is also an effect that the assembly work efficiency is improved.
