Fig. 7 and 8 are circuit diagrams of the left power switch and the right power switch, respectively, wherein KEYML and KEYMR are connected to IO interfaces of the micro control unit, respectively, for detecting states of the left and right power switches. When the user does not press the power switch, the corresponding IO interface is at a high level (3.3V); when the user presses the power switch, the corresponding IO interface is at a low level (0V). And the micro-control unit judges the triggering condition of the power switch by acquiring the low level or the high level at the IO interface.

For making the user after starting the propeller, have enough time to adjust the gesture in order to stably lie prone on the power kickboard, press the back simultaneously when controlling power switch, control assembly can control the propeller and delay behind the appointed time and start, for the user provides sufficient preparation time. The specific extended designated time can be set according to actual needs.

In order to facilitate other operations of a user in the moving process of the power floating plate, when one of the two power switches is disconnected and the other power switch is still in a triggered state, the pusher continues to work to ensure that the power floating plate continues to move forwards, one arm of the user triggers the power switch, and the other arm can perform other operations, so that the control of the power floating plate is more flexible. When the two power switches are disconnected, the control assembly controls the propeller to stop running so as to avoid the power floating plate from being separated from a user.

In some embodiments, the control assembly controls the propeller to activate when a user depresses either of the two power switches; when both power switches are not pressed, the control component controls the propeller to stop running.

The control process of the power floating plate in this embodiment is as follows:

when the power floating plate is not used, the power floating plate is not electrified. When a user presses the power switch, the power floating plate is powered on and maintains the power-on state, and the indicator lamp is lightened to indicate the current battery capacity and state information to wait for receiving an instruction. When the power switches on the left side and the right side are pressed down, level signals of the IO interface are sent to the micro control unit, and the micro control unit controls the propeller to operate at the maximum power after receiving the signals. When the power floating plate is not placed in water, the motor 3 is in an idle state, and at the moment, the power floating plate runs at the maximum idle speed. During the operation of the power floating plate, when any power switch is loosened, the propeller cannot stop operating, and only after the two power switches are all loosened, the propeller cannot stop operating.

After the power switch (for example, 3S) is pressed for a long time, the power floating plate is turned off. The power floating plate is not electrified after shutdown, and static power consumption is reduced. The battery consumes no power, and the service life of the battery is prolonged.

When the power floating plate is connected with the charger, the charger interface triggers the power floating plate to start, the micro-control unit detects that the charger is in a connection state, the indicator light indicates charging, the charging control MOS tube is turned on, and the power floating plate starts charging. And when the battery is fully charged, the micro control unit closes the charging control MOS and stops charging.
