Description

[Detailed Description of the Invention] The present invention relates to a coupling structure for a motor generator.

A power generator is widely used as a general-purpose portable power source such as a commercial frequency output, and consists of a generator, an engine that drives the generator, a main switch,
The generator is equipped with an operation panel on which an output outlet and the like are formed, and the generator and electrical components such as the operation panel are connected by wire harnesses each having a coupler interposed therein.

Conventional couplers have a large number of parts because they are installed in a coupler storage case that is separate from the engine and generator, and a separate dedicated space is required to install the storage case. There was a problem that I had to do it.

The present invention was devised in response to these problems, and it saves space by making effective use of the existing generator cover and devising a way to make the cover double as a storage case for the coupler. The purpose of this invention is to provide a wiring mounting structure for a motor generator that is compact and has an excellent appearance by reducing the number of parts and making effective use of the power.

In order to achieve the above object, the present invention provides a motor generator configured by coupling and fixing an engine and a generator driven by the engine, with an operation panel provided on the engine side. A coupler that connects electrical wiring with the generator part is configured to be attached to a mounting stay fixed to the engine side, and a cover that covers the stator of the generator is formed in a lid shape that opens toward the engine side. The cover is integrally formed with a storage portion that bulges outward in the radial direction, and when the cover is attached to cover the stator and open toward the engine side, the engine side opening of the storage portion is The end is configured to be closed by the attachment stay portion.

A preferred embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows a perspective view of a motor generator, and the motor generator 1 includes an engine 3 on one side of a base plate 2 and a generator 4 on the other side.

The engine 3 includes a cylinder barrel 5 in which a cylinder block and a crankcase are integrally molded.A cylinder head 7 with a spark plug 6 mounted thereon is attached to the upper part of the cylinder barrel 5, and a fuel tank is installed above the cylinder head 7. Install 8.

A crankcase cover 11 in which an engine cooling fan, etc. is installed is disposed on the left side of the cylinder barrel 5, and a recoil starter 12 is disposed on the left side of the crankcase cover 11. An operation panel 13 is provided, and an air cleaner is provided on the rear side.

The operation panel 13 includes a main switch 14,
It forms circuit protectors 15, 15, output outlets 16, 16, output terminals 17, 17, etc., and 18 in the figure indicates each of the aforementioned locations 14, 15, 1.
6, 17, etc., and a coupler 19a is attached to the end of the wire harness 18, as shown in the exploded perspective view of FIG.

The generator 4 includes an end frame 21 attached and fixed to the cylinder barrel 5 and the base plate 2, respectively,
A generator cover 22 is attached to the right side of the end frame 21, and as shown in a half sectional view in FIG. 3, the generator cover 22 covers the rotating shaft 23, rotor 24, stator 25, and generator cooling fan 26. As shown in FIG. 2, a coupler 19b is attached to the end of the wire harness 27 on the generator 4 side.

The generator 4 is cooled by rotating the fan 26 to blow cold air, that is, outside air, into the opening 2 of the generator cover 22.
8 and circulate inside the cover 28,
This is done by releasing it into the atmosphere from the opening 29 of the end frame 21.

The generator cover 22 is shown in FIG. 4 as a side view in half cross section, as shown in FIG. 5 in the direction of the arrow in FIG.
As shown in the half cutaway view in the direction of arrows in FIG.
A storage portion 33 is formed in the upper part of the main body portion 31 in the shape of a lid that bulges outward in the radial direction and opens toward the engine 3 side.

By attaching the generator cover 22 to the end frame 21, the open portion 32 of the housing portion 33 faces the upper surface of the end frame 21, and the couplers 19a, 19 are closed so as to close the open portion 32.
A mounting stay 34 of b is provided.

The mounting stay 34 is shown in a front view in FIG.
The figure shows the arrow view of Fig. 7, and Fig. 9 shows the - of Fig. 7.
As shown in the line cross-sectional view, there is a base plate part 35 in which the opening part 32 can be freely closed, and a storage part 33 from the base plate part 35.
and a mounting portion 36 extending toward the rear side.

The board portion 35 is attached and fixed to protrusions 41, 41 provided on the upper surface of the end frame 21 with screws 42, and is connected to the wire harness 18 on the operation panel 13 side.
The coupler 19b on the generator 4 side is fitted into the notch 45 of the mounting part 36 and the screws 46, 46 are inserted into the storage part 33 by fitting the grommet 44 into the notch 43 of the base plate part 35. Mounting part 36
The couplers 19a and 19b are fitted together, and the couplers 19a and 19b are attached via the mounting stay 34.
is airtightly stored in the storage section 33.

Note that 47 in the drawing is a pedestal attached to the end frame 21.

The present invention has the generator cover 22 as described above.
The housing portion 33 for the couplers 19a, 19b is integrally formed in the generator cover 22.
Since it is also used as a storage case for the couplers 19b, there is no need for a storage case dedicated to the couplers 19a and 19b as in the past, and the number of parts can be eliminated and costs can be reduced.

In addition, the upper part of the generator cover 22 is slightly bulged upward to form a storage section 33 for the couplers 19a and 19b.
Since the upper part of the generator cover 22, which is a dead space, is effectively used, it is not necessary to separately secure a storage space for the couplers 19a and 19b as in the conventional case, and the space efficiency of the engine generator 1 is improved. The motive power generator 1 can be made compact, and at the same time, the appearance of the motive power generator 1 can be significantly improved.

Furthermore, since the couplers 19a and 19b are exposed to the outside only after the generator cover 22 is removed, there is no risk that the couplers 19a and 19b will come off by coming into contact with an obstacle or the like during normal use with the generator cover 22 attached.

In addition, in the embodiment, the mounting stay 34 is separate from the end frame 21, but the mounting stay 34
may be integrally molded on the end frame 21, and in the embodiment, the cylinder barrel 5 and the end frame 21 are separate bodies, but in the case where the cylinder barrel 5 and the end frame 21 are integrally molded, the mounting stay 34 will be attached to the engine 3 side.

As is clear from the above explanation, according to the present invention,
Since the existing generator cover can also be used as a storage case for the coupler, there is no need to provide a separate storage section. In addition, the number of parts can be reduced, assembly and disassembly operations are easy, and a motor generator that is more compact and has an excellent appearance can be obtained.
