The invention further provides an embodiment of an automatic power changing method, please refer to fig. 10, the automatic power changing method is applied to the mower assembly, and includes the steps of:
step S10: planning a traveling route by taking the base station as a base point, and setting different electric quantity thresholds according to different positions of the mower on the traveling route;
the processing device calculates and sets electric quantity threshold values of the mower at different positions on the travelling route according to the planned travelling route, namely when the electric quantity threshold value of the mower at a position far away from the base station on the travelling route is higher than the electric quantity threshold value of the mower at a position close to the base station on the travelling route, so that the mower can work for a longer time without replacing the power supply device and still has enough electric quantity to return to the base station for replacing the power supply device. It will be appreciated that the planned path of travel of the lawnmower can be adjusted by the user to specific parameters to conform the path of travel of the lawnmower to the work area of the use scenario.
In some embodiments, after the step of planning the traveling route based on the base station and setting different charge thresholds according to different positions of the mower on the traveling route, the method further comprises:
step S11: after triggering the electric quantity threshold, the mower plans different return routes according to different traveling positions;
because the electric quantity thresholds of different positions on the traveling route are different, the position of the mower, which is far away from the base station, is also different when the electric quantity threshold is triggered, so that after the electric quantity threshold is triggered, the return route of the mower needs to be planned in combination with the current position, the operated route and the non-operated route, and the return route of the mower avoids the non-operated route, so that the mower can smoothly return to the base station.
Step S20: detecting the electric quantity of a power supply device in the mower in real time when the mower carries out mowing operation;
step S30: when the electric quantity of the power supply device reaches a preset electric quantity threshold value, controlling the mower to drive to a base station;
in some embodiments, as shown in fig. 11, when the power of the power supply device reaches a preset power threshold, the step of controlling the lawn mower to drive to the base station includes:
step S301: the mower stops mowing;
step S302: the mower marks the current lower position as a reset point according to the position signal;
step S303: the mower is driven to the base station along a return route;
step S304: and the mower adjusts the return route according to the position signal.
After the mower triggers the power threshold, in order to reduce the power loss of the power supply device, the processor suspends the operation of the working device, and ensures that the remaining power of the power supply device can support the mower to return to the base station. In order to enable the mower to automatically move to a position where the mower stops working before the power supply is replaced after the power supply device is replaced, and then continue working along a planned route, the processing device marks the current position of the mower as a reset point, and the reset point is an initial working position after the mower is replaced with the power supply device, namely a position where the working device is restarted. When the mower is driven to the base station, deviation occurs between the mower and a planned return route due to road conditions, and the mower with the deviation may not move smoothly to the base station or reach a preset position of the base station, so that the power change of the mower fails, and therefore the mower can adjust the return route according to the position signal received by the signal receiver from the signal generator, so that the mower can move smoothly to the preset position of the base station.
Step S40: when the mower reaches the preset position of the base station, controlling the electricity replacing device to replace a power supply device of the mower;
in some embodiments, referring to fig. 12, when the lawn mower reaches the predetermined position of the base station, the step of controlling the power exchanging device to exchange the power supply device of the lawn mower includes:
step S401: the control device acquires a trigger signal sent by the trigger device, and controls the door lock device to open the battery compartment;
when the mower moves to the preset position of the base station, the trigger device abuts against the mower, and the locking device locks the mower at the preset position of the base station.
Step S402: the control device acquires a feedback signal after the door lock device is opened, and the control device controls the electricity changing device to change electricity for the mower;
in other embodiments, referring to fig. 13, the step of acquiring a feedback signal after the door lock device is opened by the control device, and the step of controlling the battery replacement device to replace the battery of the lawn mower by the control device includes:
step S4021: the control device controls the grabbing mechanism to move from a first position to a second position to grab the power supply device in the battery cavity;
step S4022: the control device controls the grabbing mechanism to move from the second position to the first position so that the power supply device is placed in the battery placing cavity;
step S4023: the control device controls the first driving mechanism to drive the bracket to move from a third position to a fourth position;
step S4024: the control device controls the grabbing mechanism to move from the first position to the second position, so that the power supply device is contained in the battery cavity from the battery placing cavity;
step S4025: the control device controls the grabbing mechanism to reset from the second position to the first position.
Step S403: the control device controls the door lock device to close the battery compartment and controls the locking device to unlock after acquiring a reset signal of the first driving motor;
step S404: the signal generator sends a driving-away signal to the signal receiver, and the processor receives the driving-away signal transmitted by the signal receiver and controls the mower to drive away from the base station.
