The invention can realize the switching between the P2 mode and the P3 mode by one motor, greatly save the cost, effectively solve the problem of the failure of the motor 14, carry out power transmission by the engine 1, enlarge the application range of equipment, carry out idle charging and ensure the sufficient power of the motor.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
