Embodiment Construction

[0087] figure 1 with figure 2 The driving schematic diagram of the electric lawn mower of the present invention changing with time t is disclosed. Except for the control unit, the lawn mower of the present invention has a traditional structure and includes an electric blade motor for rotating and driving the cutting blades. The blade motor is operatively connected to a battery; used to drive the lawn mower along the lawn that needs to be trimmed The electric drive motor is operatively connected to the battery. Reference Figure 4 to Figure 7 As will be described, the present invention provides a control unit and associated components for controlling the movement of the lawn mower through the blade motor and the driving motor. Preferably, the electric drive motor acts on at least one rear wheel.

[0088] In order to more easily explain the purpose of the present invention, in figure 1 In, it is set that the operator does not push the lawnmower, so the operator does not perform a...

Abstract

The invention discloses a self-driven mower. The self-driven mower comprises an airborne battery, an electric blade motor, an electric driving motor, a control unit, a speed monitor, a movement speed selector, and a total energy monitor, wherein the electric blade motor is used for rotatably driving a mowing blade; the electric driving motor is used for driving the mower to move along a lawn needing to be mown; the control unit is used for at least controlling the operation of the electric driving motor and the electric blade motor; the speed monitor is used for monitoring the speed of the driving motor; the movement speed selector is used for selecting the preset speed for the driving motor; the total energy monitor is used for monitoring the total energy consumption of the battery, and the total energy consumption is the sum of the electric energy consumed by the driving motor and the electric energy consumed by the blade motor; an operator can select the preset maximum total energy value through the maximum total energy selector; and the control unit is used for keeping the speed of the mower be the preset speed independent of the thrust of the operator, and when the total energy value exceeds the preset maximum total energy value, the control unit can reduce the total energy. The mower has the advantages of comfortable operation and no overload of the battery.
