Abstract

PURPOSE:To provide an engine incorporating a cell motor and a power source battery, which may eliminate such a defect that self-sustaining discharge is excessive if a nickel cadmium battery is used as the power source battery in order to miniaturize the engine, and the cell motor cannot be rotated at the next start if it is not rotated for a long time. CONSTITUTION:In an engine starting mechanism incorporating an cell motor 3 and a power source battery 7, a solar battery 1 having a power generation exceeding a self-sustaining discharge of the power source battery 7 is applied on the outer surface of a starter casing 5.

Description

Detailed Description of the Invention

The present invention relates to a battery charging mechanism for an electric starting device equipped with a starter motor and a power source battery as an engine starting device.

[0002]

2. Description of the Related Art A technique equipped with a starter motor and a power battery as an electric starting mechanism for an engine is disclosed in Japanese Patent Laid-Open No. 2-10.
The technique described in Japanese Patent No. 8856 is known.

[0003]

However, in the above-mentioned prior art, when a CADNICA battery is used as a power source battery in order to miniaturize the engine, a large amount of spontaneous discharge (lead battery is 3% / month). On the other hand, 20-25
% / Month), if left unrotated for a long time, there is a problem that the starter motor 3 does not rotate at the next start. In order to solve this problem, charging by an external charging device or a charging coil inside the engine is required. At this time, the maintenance work of the battery by the external charger and the charging work in the idle operation after the manual start were complicated. In the present invention, instead of the external charger, a charging device aiming at supplementing the self-discharged amount of the battery is constituted by a solar battery, and is always attached to the engine.

[0004]

The problems to be solved by the present invention are as described above, and the means for solving the problems will be described below. That is, in a starting device for an engine equipped with a starter motor 3 and a power supply battery 7, a solar battery 1 for charging the power supply battery 7 is provided at the same time, and the solar battery 1 is provided on an outer surface of a starter case 5 constituting the starting device. It is attached.

[0005]

[Operation] Next, the operation will be described. That is, while the engine is rotating, the electric power generated by the generator attached to the engine is supplied to the spark plug in the case of a gasoline engine, and the extra power is charged in the power supply battery 7. When the engine is once stopped and then restarted, the starter switch 2 is turned on to rotate the starter motor 3 by the electric power from the power source battery 7 to start the engine. However, if the rotation of the engine is stopped for a long period of time, the power supply battery 7 is gradually discharged, and when the engine is restarted next time, there may be a case where sufficient electric power to drive the starter motor 3 is not stored. Of. The present invention, even in the case of the long-term rotation,
As long as there are light rays, the solar battery 1 is attached to the power supply battery 7 as a device for charging the electric power more than the discharge amount. As a result, the amount of charge from the solar battery 1 to the power supply battery 7 is larger than the amount of natural discharge from the power supply battery 7, so that the stored power of the power supply battery 7 does not decrease.

EXAMPLES Next, examples of the present invention will be described. FIG. 1 is a side view of an engine having an engine starting mechanism with a solar charging device of the present invention, FIG. 2 is a perspective view of a solar battery 1 removed from a starter case 5, and FIG. 3 is a starter case 5.
4 is a plan view showing a state in which a solar battery 1 is attached to the outer surface of the upper surface of FIG. 4, FIG. 4 is a plan view showing another embodiment in which the shape of the solar battery 1 is different, and FIG. 5 is an engine starting mechanism with a solar charging device of the present invention. It is an electric circuit diagram.

In FIG. 1, the engine is constructed around a cylinder block 15. The cylinder block 1
A fuel tank 13 is placed on the upper surface of the fuel cell 5. Further, a muffler 8 is projected on the upper surface of the cylinder block 15, and an air cleaner 9 is arranged laterally. An operation panel 19 is arranged below the fuel tank 13 and between the manual starter handle 4. The operation panel 1
The starter switch 2 is also arranged on the surface of 9. The engine starting mechanism with a solar charging device, which is an essential part of the present invention, is arranged in the vicinity of the starter case 5 attached to the side surface of the cylinder block 15.

A starter case 5 attached to a side surface of a cylinder block 15 of the engine is provided with a starter motor 3, a power supply battery 7, and a manual starter handle 4.
The solar battery 1 is attached to a part of the outer surface of the starter case 5. Next, referring to FIGS. 2, 3, and 4, the structure of the starter case 5 provided with the solar battery 1 will be described. In this embodiment, there is disclosed a starting mechanism provided with an electric cell starter and a recoil starter device that enables manual starting when the electric cell starter cannot be started due to discharge of the power supply battery 7. ing.

Inside the starter case 5, a pulley for winding up and storing the recoil wire extended to the manual starter handle 4 and a gear type power transmission mechanism for rotating the crankshaft by the starter motor 3 are arranged in parallel. is there.
Then, in the space below the starter motor 3, the power supply battery 7
Is arranged. A starter switch 2 for turning the circuit on and off is provided between the power source battery 7 and the starter motor 3, and the starter switch 2 is provided.
Are arranged on the surface of the operation panel 19 as shown in FIG.

In the present invention, the solar battery mounting surface 6 is provided on the outer surface of the starter case 5 made of aluminum casting, resin or the like, and the solar battery 1 is attached to the solar battery mounting surface 6. As a matter of course, the solar battery 1 needs light, and it is best that the light is not obstructed by the fuel tank 13 on the upper surface of the starter case 5. A coupler 11 is extended below the solar battery 1, and the coupler 11 is connectable to a coupler 12 extended from the power battery 7. Further, the starter case 5 is provided with a wire hole 4a into which the recoil wire of the manual starter handle 4 is inserted.

FIG. 3 discloses the configuration of an embodiment in which the solar battery 1 is attached to the side as wide as possible in order to mount the solar battery 1 on as wide a surface as possible. Further, FIG. 4 discloses an embodiment in which the solar battery 1 is formed in a rectangular shape and does not protrude to the portion of the wire hole 4a.
In FIG. 5, an electric circuit diagram of an engine starting mechanism with a solar charging device of the present invention is disclosed. Power generation by the solar battery 1 is always performed as long as there is a light beam, and the power generated by the solar battery 1 is designed to be larger than the power of natural discharge of the power battery 7. Then, when the solar battery 1 is turned on by the electric power charged in the power source battery 7, the starter motor 3 is driven. Further, when the engine is rotating, the power from the generator of the engine is supplied to the power source battery 7
Of course, it will be charged.

[0012]

Since the present invention is configured as described above, it has the following effects. That is, when the storage period is not used, such as an engine mounted on an agricultural machine, it is often impossible to start the starter switch 2 next time due to spontaneous discharge of the power supply battery 7. As described above, since the solar battery 1 having a power generation amount and a charge amount exceeding the natural discharge amount of the power source battery 7 is attached to the engine, the chance of starting by the manual starter handle 4 is reduced.
