Background

With the continuous development of economic society of China, various application equipment with small gasoline engines is increasing day by day, and most of the starting modes are manually started, so that the starting mode is easy to cause starting difficulty in winter severe cold seasons in the north of China; moreover, the manual start greatly increases the labor intensity of the user. Therefore, the urgent need of users is to change the manual starting of the small gasoline engine into the electric starting. In addition, because some equipment engines have high working rotating speed (6500 rpm, 8000 rpm at the highest rotating speed), the existing electric starting mode is that a pinion (with an overrunning clutch) on a starting motor drives a gearwheel on a flywheel to start, after the engine is started, the rotating speed of the pinion reaches tens of thousands of revolutions or even hundreds of thousands of revolutions, and the common overrunning clutch is difficult to adapt to the high rotating speed after the engine is started and cannot work normally.

Therefore, the stable, convenient and cheap electric starting device becomes a technical problem to be solved urgently for changing the starting mode of the small gasoline engine.

Further, the number of the mounting holes is at least two.

Further, the starting dial comprises a starting dial body, a starting dial claw and a return torsion spring.

Further, still be equipped with the motor control module of control starter motor rotational speed on the starter, control module electricity signal connection starter motor, still be connected with corresponding power module on the control module, or control module is connected with power supply electricity.

Compared with the prior art, the utility model the advantage lie in:

the hand-pulling starting device in the prior art is improved to be in an electric starting mode, a specific improved part is one part of the starter, and specifically the structure of a starting motor, a ratchet wheel and a starter shell is improved, so that the purposes of convenient operation and low improvement cost are realized on the basis of realizing electric starting, and the hand-pulling starting device is high in functionality;

through addding power supply or power source to the purpose of realizing the power supply on the different modes has been reached, and the practicality is strong, convenient to use.

Detailed Description

The present invention will be described in further detail with reference to the accompanying fig. 1-4.

The electric starting device capable of rapidly replacing the starting mode of the hand-pull starting type small gasoline engine comprises a starter and a starting drive plate, wherein the starter comprises a starter shell 1, a power supply source or power interface 2, a starting motor 3 and a ratchet wheel 4 positioned on the starting motor 3, a mounting hole 5 is formed in the starter shell 1, the ratchet wheel 4 and the power interface 2 are respectively positioned on the front side and the rear side of the starter shell 1, and the ratchet wheel 4 is coaxially connected with the starting motor 3; the right-angled tooth surface on the ratchet wheel 4 is pressed against a starting claw on a flywheel on an engine crankshaft after the starting motor 3 is electrified and rotated.

At least two mounting holes 5 are provided.

The starting drive plate comprises a starting drive plate body, a starting drive claw and a return torsion spring.

Still be equipped with the motor control module 6 of control starter motor 3 rotational speed on the starter, control module 6 signal connection starter motor 3, still be connected with corresponding power module 7 on control module 6, or control module 6 is connected with power supply.

The starting part of the small gasoline engine which is manually started in the prior art mainly comprises a starter and a starting drive plate; the starter mainly comprises a starter shell, a starting handle, a pull rope, a starting wheel, a return spring, a fastening screw and the like. The starting drive plate mainly comprises a starting drive plate body, a starting drive claw, a torsion spring and the like.

The electric starting device mainly comprises a starter shell 1, a power supply or power interface 2, a starting motor 3, a starting ratchet wheel 4 arranged on the starting motor 3 and a motor control system, namely a control module 6, wherein the power supply, the starting motor and the motor control system replace an original starting handle, a pull rope, a starting wheel, a return spring and the like, and a starting dial plate combined with the starter keeps the original starting dial plate unchanged. When the starting device is assembled, the original hand-pull starter is disassembled, and the starting device is installed in place through the installation screw hole of the original hand-pull starter by using the screw, so that the upgrading and the transformation of the starting mode are completed.

When an engine needs to be started, a starting button is pressed, a power supply source in an electric starting device supplies power to a starting motor 3 (an outer rotor brushless motor), a starter shell 1 is connected with a ratchet wheel 4 arranged on the starter shell to rotate anticlockwise, a right-angle tooth surface of the ratchet wheel 4 props against a starting claw on a flywheel fixed on an engine crankshaft to enable the starting flywheel and the engine crankshaft to rotate, and an engine connecting rod drives an engine piston to move up and down in an engine cylinder to suck mixed gas; when the rotating speed reaches the starting rotating speed of the engine, a starting flywheel arranged on a crankshaft of the engine rotates to enable a starting coil to emit high-voltage electricity, and the gasoline engine is started by ignition of a spark plug.

Therefore, the power transmission process in the starting process determines that strict coaxiality requirements between the starting ratchet wheel 4 and the starting drive plate are not needed, so that for different engines, only the mounting hole 5 on the starter shell 1 is matched with the screw hole on the engine box body, and the starting ratchet wheel 4 is correspondingly adjusted according to the size and the position of the starting drive claw on the starting drive plate, and special professional technology is not needed for replacement and installation.

The present invention and the embodiments thereof have been described above, but the description is not limited thereto, and the embodiment shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. In summary, those skilled in the art should understand that they should not be limited to the embodiments described above, and that they can design the similar structure and embodiments without departing from the spirit of the invention.
