The arc-shaped opening improves the drainage effect of the oil, and the top plate 22 plays a supporting effect. The rotation of the rotating shaft 43 is controlled by the drive unit 4 to link the operation of the hydraulic unit 23, so that the pressure in the oil pump is changed, and the oil is sucked from the oil tank to the oil inlet 10 and enters the oil pump. When a certain pressure is applied to the oil, it flows out from the oil outlet 30 and is continuously supplied to the engine.

[0029] As an embodiment further provided by the present invention, the hydraulic unit 23 includes a pump outer ring 230, a roller 231 and a turntable 232. The pump outer ring 230 is arranged on the outer casing 2, and the turntable 232 is arranged at an eccentric position of the pump outer ring 230. The turntable 232 is provided with column grooves in a circular array, and the rollers 231 are arranged in the column grooves. The turntable 232 cooperates with the rotating shaft 43. When the drive unit 4 is started, the turntable 232 is rotated by the rotating shaft 43, so that the multiple rollers 231 on the turntable 232 rotate along the pump outer ring 230, thereby changing the pressure in the oil pump.

[0036] Working principle: First, the electrical signal is connected through the plug 31 and transmitted to the controller 46 through the lead column 321. The controller 46 controls the rotor 45 to rotate at the axis of the outer stator 42, and the relative shaft 43 rotates synchronously with the rotor 45, and the turntable 232 rotates synchronously, thereby pushing the roller 231 located in the outer ring 230 of the pump to roll, so that the pressure in the pump body changes, thereby sucking oil from the oil inlet 10 into the oil pump, and after a certain pressure is applied to the oil, the oil flows out from the oil outlet 30 and is continuously supplied to the engine.
