As shown in Figures 1 and 2, the riding lawn mower 100 includes: a cutting assembly 10, a frame 91, a seat 92, a housing system 20, a walking assembly 93, a power assembly 96, a lighting system 40, and an operating assembly 50. Among them, the seat 92 is installed on the frame 91 for users to sit on. The frame 91 carries the seat 92. The frame 91 and the housing system 20 constitute the main body 100a of the riding lawn mower 100, and the main body 100a is used to install the cutting assembly 10, the seat 92, the power assembly 96, and the lighting system 40. The walking assembly 93 is used to support the main body 100a. The riding lawn mower 100 provides energy for the cutting assembly 10, the walking assembly 93, the lighting system 40, etc. through the power assembly 96, so that the riding lawn mower 100 can be used as an electric tool. Compared with the fuel-type riding lawn mower 100, the electric riding lawn mower 100 is more environmentally friendly and more energy-saving. In some embodiments, the riding lawn mowing device 100 includes a grass collecting device. The grass collecting device is used to collect grass clippings cut by the cutting assembly 10. The grass collecting device includes a grass collecting basket assembly, which is detachably mounted behind the seat 92.

Specifically, the cutting assembly 10 is used as a power output member for outputting power to realize the function of the riding mowing device 100. The cutting assembly 10 is arranged below the frame 91. In this embodiment, the cutting assembly 10 includes: a blade 11, a mowing element 12 and a mowing motor 13. The mowing element 12 is used to cut vegetation when rotating at a high speed. For example, the mowing element 12 is a blade for cutting grass on a lawn. The blade 11 is surrounded by a mowing space 121 that is open downward and is used to accommodate at least part of the mowing element 12. That is, the mowing element 12 is at least partially accommodated in the blade 11, and the mowing motor 13 is used to drive the mowing element 12 to rotate. In some embodiments, the number of mowing elements 12 can be 2, and the number of mowing motors 13 is 2. Accordingly, two mowing motors 13 drive two mowing elements 12 respectively. In some embodiments, the number of mowing elements 12 can be 3, and the number of mowing motors 13 is 3. Accordingly, three mowing motors 13 drive three mowing elements 12 respectively.

Of course, the cutting assembly 10 can also be detached from the riding lawn mower 100. In some embodiments, the riding lawn mower 100 can be connected to other working accessories, such as a snow shovel assembly. At this point, strictly speaking, the riding lawn mower 100 is no longer just a riding lawn mower, but a riding snow blower that can perform different tasks according to the different working accessories connected.

The walking assembly 93 is used to support the frame 91 so that the riding lawn mowing device 100 can walk on the ground. In the present embodiment, the walking assembly 93 includes a first walking assembly 931 and a second walking assembly 932. Among them, the first walking assembly 931 is the front walking assembly, and the second walking assembly 932 is the rear walking assembly. The first walking assembly 931 includes two first walking wheels, namely the left first walking wheel 931L and the right first walking wheel 931R. The second walking assembly 932 includes two second walking wheels, namely the left second walking wheel 932L and the right second walking wheel 932R. Among them, the radius of the second walking wheel is greater than the radius of the first walking wheel. The walking assembly 93 also includes a walking motor 933 for driving the second walking assembly 932.

The operating assembly 50 includes a control panel 52, a steering wheel assembly 56 and a pedal assembly. The pedal assembly includes a throttle assembly 591 and a brake assembly 592. The steering wheel assembly 56 includes a steering wheel 561, which can be operated by a user to control the direction of travel of the riding lawn mowing device 100. The control panel 52 includes a display screen 51 and a plurality of operating elements. The display screen 51 is used to display the status information of the riding lawn mowing device 100. The plurality of operating elements can be operated by a user to control the status of the riding lawn mowing device 100. In some embodiments, the operating elements may include switches, buttons, shifting elements, etc. of different shapes or sizes.

Specifically, as shown in FIG. 3 , the display screen 51 includes a display interface 510 for displaying the working state of the riding lawn mower 100. The display interface 510 is understood to be a display area directly observed by the user. Different status information can be displayed on the display interface 510 as needed. The display interface 510 can display the travel speed of the walking component 93, the rotation speed of the mowing element 12, the energy efficiency state of the riding lawn mower 100, the remaining power information of the power supply component 96, warning information, fault information, the remaining operating time of the power supply component, etc.

In some embodiments, the operating member includes a plurality of buttons arranged around the display interface 510. For example, the first button 511 and the second button 512 are respectively used for the user to operate to adjust the travel speed and blade speed of the riding lawn mower 100. The first button 511 and the second button 512 can be respectively arranged on the left and right sides of the display interface 510. A third button 513 is also arranged around the display interface 510 for the user to operate to control the lighting function of the riding lawn mower 100. For example, when the user operates the third button 513 using the first operation mode, the lighting system 40 turns on part of the lighting lamps. When the user operates the third button 513 using the second operation mode, the lighting system 40 turns on all the lighting lamps. In this embodiment, a fourth button 514 is also arranged around the display interface 510, and the fourth button 514 can be operated by the user to make the riding lawn mower 100 enter different driving modes, such as the sports mode, the standard mode and the control mode. In this way, the user can select different driving modes according to personal preferences, thereby improving the user experience of the riding lawn mower 100. At this time, information about different driving modes of the riding lawn mower 100 can also be displayed on the display interface 510. The fourth button 514 can also be operated by the user in different operating modes to perform other configurations of the riding lawn mower 100, for example, long pressing the fourth button 514 switches the driving mode, and short pressing the fourth button 514 enters the setting menu. The third button 513 and the fourth button 514 can be set at the lower side of the display interface 510.

In some embodiments, the operating member further includes a start button 552 and a key hole 554. When the key is inserted into the key hole 554, the riding lawn mower 100 can be started, and when no key is inserted into the key hole 554, the power of the riding lawn mower 100 is cut off and cannot be started. When the start button 552 is triggered, the riding lawn mower 100 enters a standby state, and at this time, the user can operate other operating members to make the riding lawn mower 100 enter a walking state or a mowing state, etc.

In some embodiments, the operating member further includes a PTO switch 555. The PTO switch 555 has a first position and a second position. When the PTO switch 555 is set to the first position, the mowing element rotates. When the PTO switch 555 is set to the second position, the mowing element stops. The PTO switch 555 is in the first position when it is lifted, and in the second position when it is pressed. When the user finds an emergency, he only needs to press the PTO switch 555 to stop the mowing element in an emergency, and the operation is quick and convenient.

In some embodiments, the operating element further includes a cruise control button 556. When the cruise control button 556 is triggered, the riding lawn mower 100 receives the cruise control instruction issued by the user and decides whether to enter the cruise control mode according to the current state.

In some embodiments, as shown in FIG. 4 , the riding lawn mower 100 further includes a control device for controlling the state of the riding lawn mower 100. In this embodiment, the control device at least includes a signal circuit 951, a main control circuit 952, and a display circuit 953. The signal circuit 951 is used to receive the state information of the riding lawn mower 100 and transmit it to the display circuit 953 of the display screen 51. The signal circuit 951 is also responsible for receiving the switch signals of each operating member on the control panel 52 and transmitting them to the main control circuit 952. The main control circuit 952 is used to control the cutting assembly 10 and the traveling assembly 93. For the cutting assembly 10, the main control circuit 952 can control the operation of the lawn mower motor 13. For the traveling assembly 93, the main control circuit 952 can control the operation of the traveling motor 933. Specifically, the main control circuit 952 includes at least one controller, such as some dedicated control chips.

In some embodiments, the main control circuit 952 has a first state that prohibits the travel motor 933 from starting and a second state that allows the travel motor 933 to start. When the main control circuit 952 is in the first state, the user cannot start the travel motor 933 through the operating component 50 on the riding lawn mower 100. When the main control circuit 952 is in the second state, the user can start the travel motor 933 by triggering the throttle component 591. In this embodiment, when the main control circuit 952 is in the first state, the lawn mower motor 13 is also prohibited from starting. Specifically, the main control circuit 952 is configured to switch from the first state to the second state at least when the output trigger signal of the start key 552 is obtained and the brake component 592 is detected to be operated. In this way, it can effectively avoid the unconscious start of the travel motor 933 due to the user's misoperation of the throttle component 591, thereby improving the safety of the riding lawn mower 100.

When the user inserts the key into the keyhole 554, the riding lawn mower 100 enters the standby state. When the user triggers the start button 552, the display screen 51 is awakened, and the display interface 510 of the display screen 51 is the first display interface. Among them, the first display interface is used to display the current remaining power of the power supply component 96. When the display screen 51 is the first display interface, the main control circuit 952 is in the first state of prohibiting the start of the travel motor 933 or the lawn mower motor 13. It can be understood that when the display screen 51 is in the first display interface, the user cannot control the start of the travel motor 933 or the lawn mower motor 13 through the operating component 50 of the riding lawn mower 100.

When the display screen 51 enters the first display interface and the key is located in the keyhole 554, the main control circuit 952 controls the display screen 51 to switch from the first display interface to the second display interface after detecting that the start key 552 is in the triggered state and the brake assembly 592 is operated. A trigger signal is output when the start key 552 is in the triggered state. Specifically, when the user wants to perform mowing or walking, the start key 552 needs to be continuously triggered. The difference is that this triggering needs to last for a long time, such as 3 seconds. After the user continuously triggers the start key 552, the brake assembly 592 needs to be operated to enable the display screen 51 to enter the second display interface from the first display interface. Among them, the second display interface is the power-on interface. In this embodiment, the brake assembly 592 is operated, including the brake assembly 592 being released after being triggered. In some embodiments, when the user operates the start key 552 in the triggered state and has not yet operated the brake assembly 592, a flashing icon will appear on the display screen 51 to remind the user to operate the brake assembly 592.

Thus, when the user attempts to start the travel function of the riding lawn mower 100, the user needs to actively operate the brake assembly to trigger and release it. The above arrangement can improve the safety of the riding lawn mower 100 when starting, and prevent the user from accidentally stepping on the accelerator assembly to start the travel motor without realizing it.

Of course, in the above-mentioned embodiments, the method of operating the brake component is selected to express the user's intention to start the driving function of the device. In some embodiments, the riding lawn mower device 100 also includes an operating member for at least executing the start-up operation that the user wants to give to the riding lawn mower device, and the main control circuit is configured to switch from the first state to the second state when at least the start-up operation that the user wants to give to the riding lawn mower device is obtained. Specifically, the above-mentioned operating member can be a brake component, and can also be a biometric component, such as a fingerprint recognition component, a face recognition component. In some embodiments, the above-mentioned operating member can also be a gear member for controlling the riding lawn mower device to move forward or backward. In some embodiments, the above-mentioned operating member can also be a dedicated button.

Next, a control method for switching the display interface 510 of the display screen 51 from the first display interface to the second display interface is described in conjunction with FIG. 5 . The specific steps are as follows:

S10: Briefly trigger the start button.

S11: Controlling the display interface of the display screen to be the first display interface.

The first display interface is used to display the remaining power of the current power supply component.

S12: Determine whether the key is in place. If yes, execute step S13; if no, execute step S17.

When the key is inserted into the keyhole, it is considered that the key is in place; when the key is not inserted into the keyhole, it is considered that the key is not in place.

S13: Is it determined whether the start button is in the triggered state and the brake assembly is triggered? If yes, execute step S16; if no, execute step S14.

When the display interface of the display screen is the first display interface, the user needs to press and hold the start button for about 3 seconds, and at the same time, the user needs to trigger the parking component.

S14: Determine whether the parking component is triggered. If yes, execute step S13; if no, execute step S15.

S15: The parking icon on the display interface of the display screen flashes, and step S13 is executed.

When the parking icon on the display interface of the display screen flashes, the display interface of the display screen cannot be successfully switched from the first display interface to the second display interface. When the user observes that the parking icon flashes, the user needs to select to trigger the brake component.

S16: Controlling the display interface of the display screen to switch from the first display interface to the second display interface.

S17: Determine whether the start key is briefly triggered, if so, execute step S18; if not, execute step S11.

S18: Enter the shutdown interface.

It should be noted that the display interface 510 of the display screen 51 entering the second display interface is a prerequisite for the main control circuit 952 to switch from the first state to the second state. In other words, only when the display interface 510 of the display screen 51 is the second display interface, the main control circuit 952 can switch from the first state that prohibits the start of the travel motor 933 to the second state that allows the start of the travel motor 933.

In some embodiments, when the display interface 510 of the display screen 51 enters the first display interface, if the user does not perform other operations on the riding lawn mower 100 for a long time, the main control circuit 952 will control the riding lawn mower 100 to enter a dormant state. When the user wants to wake up the riding lawn mower 100 again, the start key 552 needs to be triggered again. In some embodiments, when the display interface of the display screen 51 is the first display interface, after the user briefly triggers the start key 552 again, the main control circuit 952 controls the display interface of the display screen 51 to enter a shutdown interface. After the display screen 51 enters the shutdown interface for a period of time, the main control circuit 952 controls the riding lawn mower 100 to enter a dormant state. When the user wants to wake up the riding lawn mower 100 again, the start key 552 needs to be briefly triggered again.

Next, a control method for switching the main control circuit 952 from a first state in which the travel motor 933 is prohibited from being started to a second state in which the travel motor 933 is permitted to be started is described.

When the display interface 510 of the display screen 51 is the second display interface, that is, the display interface 510 is the power-on interface, the main control circuit 952 switches from the first state of prohibiting the travel motor 933 from starting to the second state of allowing the travel motor 933 to start, and the following conditions must be met: (1) the seat switch is in the triggered state; (2) the brake assembly is in the released state; (3) there is no travel error code. The main control circuit 952 switches from the first state to the second state when all the above conditions are met. When the main control circuit 952 is in the second state, when the user steps on the throttle assembly 591, the travel motor 933 starts and drives the riding lawn mower 100 to move. Among them, the seat switch in this embodiment is set on the seat. When the user sits on the seat, the seat switch is considered to be in the triggered state, and when the user leaves the seat, the seat switch is considered to be in the non-triggered state. When a travel error code appears on the display interface of the display screen 51, the user can eliminate the error code by operating the brake assembly 592.

In some embodiments, the control panel 52 further includes a first state indicating unit 515, which has a first indicating state for indicating that the travel motor 933 is prohibited from starting and a second indicating state for allowing the travel motor 933 to start. When the first state indicating unit 515 switches from the first indicating state to the second indicating state, the main control circuit 952 switches from the first state to the second state accordingly. In some embodiments, the first state indicating unit 515 is set as an LED light. When the LED light is off, the state indicating unit 515 is in the first indicating state. When the LED light is on, the first state indicating unit 515 is in the second indicating state. Specifically, when the state indicating unit 515 switches from the first indicating state to the second indicating state, the following conditions must be met: (1) the seat switch is in the triggered state; (2) the brake assembly is in the released state; (3) there is no travel error code; (4) the throttle assembly is in the released state. It should be noted that in this embodiment, a second state indicating unit different from the first state indicating unit 515 is also included. Specifically, the second state indicating unit is used to indicate the state of a specific operating member. For example, whether the start key is triggered, whether the seat switch is triggered, or whether the key is inserted into the keyhole, etc. The second state indicating unit may also be used to indicate the state of the throttle assembly or the brake assembly.

Next, the control method of switching the main control circuit 952 from the first state prohibiting the start of the travel motor 933 to the second state allowing the start of the travel motor 933 is described in conjunction with FIG. 6. The specific steps are as follows:

S20: The display interface of the display screen is the second display interface.

The second display interface can be understood as a startup interface.

S21: Is the seat switch in the triggered state, the brake assembly in the released state, and there is no travel error code on the display screen? When the above conditions are met at the same time, step S22 is executed; if any of the conditions is not met, step S21 is executed.

S22: The status indicator light is on.

The status indicator light is on, which is equivalent to the main control circuit switching from the first state that prohibits the travel motor from starting to the second state that allows the travel motor to start.

S23: Depress the accelerator pedal assembly.

S24: Travel motor starts.

In some embodiments, when the main control circuit 952 is in the second state, the seat switch switches from the triggered state to the non-triggered state when the user leaves the seat, and then the main control circuit 952 switches from the second state to the first state, and the display interface 510 of the display screen 51 is still the second display interface. When the user sits on the seat again, so that the seat switch switches from the non-triggered state to the triggered state, the main control circuit 952 switches from the first state to the second state after obtaining that the brake assembly is operated. The advantage of this is that when the user gets off and gets on again while operating the riding lawn mowing device 100 to mow the lawn, the user needs to operate the brake assembly again to allow the travel motor to start, thereby improving its safety and effectively avoiding accidental start-up.

In some embodiments, when the display interface of the display screen 51 is the second display interface, that is, after the power-on interface, when the user wants to start the mowing motor 13, he only needs to lift the PTO switch 555. It has been introduced above that when the PTO switch 555 is lifted, the mowing element rotates. When the PTO switch 555 is pressed, the mowing element stops. It should be noted that the user needs to sit on the seat 92 to complete the operation of lifting the PTO switch 555, otherwise the mowing motor 13 cannot be started. Of course, when the main control circuit 952 obtains the blade disc error code, even if the user triggers the seat switch and lifts the PTO switch 555, the mowing motor 13 cannot be started. In short, the conditions for starting the mowing motor 13 at least include that the seat switch is in the triggered state, the PTO switch 555 is lifted, and the main control circuit 952 does not receive the blade disc error code.

Next, the control method of the main control circuit 952 to control the start of the mowing motor 13 is introduced in conjunction with FIG. 7 . The specific steps are as follows:

S30: The display interface of the display screen is the second display interface and the power-on interface.

S31: Determine whether the seat switch is in a triggered state and there is no knife disc error code. When the above conditions are met at the same time, execute step S32; if any of the conditions is not met, execute step S31.

S32: Lift PTO switch

S33: The mowing motor starts and the mowing element starts working.

The above describes in detail the control method of the riding lawn mower 100 during the startup phase. The above control method can effectively prevent the user from accidentally stepping on the accelerator assembly to start the travel motor, thereby improving the safety performance of the riding lawn mower 100.

In order to meet the needs of users, the existing riding lawn mower 100 is provided with an operating member for controlling the travel assembly 93 to move forward or backward. In the related art, when the user operates the riding lawn mower 100 to move forward, when it is necessary to control it to move backward, it is necessary to first release the throttle assembly and trigger the brake assembly to make the speed of the travel motor 933 zero or the forward speed of the riding lawn mower 100 zero, and then operate the operating member to control the riding lawn mower to move backward. In other words, when the existing riding lawn mower 100 switches between forward and backward, it is necessary to first release the throttle and brake until the riding lawn mower 100 stops.

In the present application, the operating member also includes an operating lever 553 that can be operated by the user. The operating lever 553 is connected to the main control circuit 952 and is used to control the riding lawn mowing device 100 to switch between the forward state and the backward state. Specifically, the operating lever 553 has three gears that can be operated by the user. Specifically, the operating lever 553 has a forward gear, a backward gear and a neutral gear. The operating lever 553 has a first position when it is set in the forward gear, a second position when it is set in the backward gear, and a third position when it is set in the neutral gear. Among them, when the operating lever 553 is set in the first position, the riding lawn mowing device 100 is in the forward state. When the operating lever 553 is set in the second position, the riding lawn mowing device 100 is in the backward state. When the riding lawn mowing device 100 is in the forward state, the user can control the forward speed of the riding lawn mowing device 100 through the throttle assembly 591. When the riding lawn mowing device 100 is in the reverse state, the user can also control the reverse speed of the riding lawn mowing device 100 through the throttle assembly 591 .

In some embodiments, when the operating lever 553 is operated through at least two gears, the riding lawn mower 100 can be switched between the forward state and the reverse state. Specifically, when the operating lever 553 is operated from the forward gear to the neutral gear and then to the reverse gear, the main control circuit 952 controls the travel motor 933 to switch from the first rotation state to the second rotation state. When the operating lever 553 is operated from the reverse gear to the neutral gear and then to the forward gear, the main control circuit 952 controls the travel motor 933 to switch from the second rotation state to the first rotation state. When the travel motor 933 is in the first rotation state, the riding lawn mower 100 travels forward. When the travel motor 933 is in the second rotation state, the riding lawn mower 100 travels backward.

Specifically, when the operating lever 553 is in the forward gear and the throttle assembly 591 is in the triggered state, the riding lawn mower 100 moves forward at a corresponding speed in response to the state of the throttle assembly 591. If the user wants to control the riding lawn mower 100 to move backward, there is no need to release the throttle assembly 591. The user only needs to adjust the operating lever 553 from the forward gear to the neutral gear and the reverse gear in sequence to achieve the switch from the forward state to the reverse state. In the above switching process, the speed of the travel motor 933 gradually decreases to 0 and then directly rotates in the reverse direction to accelerate to a state matching the throttle assembly 591, thereby driving the riding lawn mower 100 to move backward. Similarly, when the operating lever 553 is in the reverse gear and the throttle assembly 591 is in the triggered state, the riding lawn mower 100 moves backward at a corresponding speed in response to the state of the throttle assembly 591. If the user wants to control the riding lawn mower 100 to move forward, there is no need to release the throttle assembly 591. The user only needs to adjust the operating lever 553 from the reverse gear to the neutral gear and the forward gear in sequence to achieve the switch from the reverse state to the forward state. In the above switching process, the speed of the travel motor 933 gradually decreases to 0 and then directly rotates forward to accelerate to a state matching the throttle assembly 591, thereby driving the riding lawn mower 100 to move backward. It should be noted that the forward rotation of the travel motor 933 means that the travel motor 933 is in the first rotation state, and the reverse rotation of the travel motor 933 means that the travel motor 933 is in the second rotation state.

The advantage of this is that the above-mentioned method for switching between the forward state and the reverse state can improve the user's experience when switching between forward and reverse. There is no need to release the throttle, and the forward or reverse switching can be achieved by simply switching the gear of the operating lever 553. The neutral position in this embodiment also has the function of stopping. When the user adjusts the operating lever 553 to the neutral position, the speed of the travel motor 933 will not be controlled by the throttle assembly 591. Specifically, when the operating lever 553 is operated to the neutral position, the main control circuit 592 controls the travel motor 933 to slow down or directly stop driving the travel motor 933 when it detects that the operating lever 553 is in the neutral position.

In some embodiments, the main control circuit 592 is configured to obtain device parameters during the riding lawn mower device 100 and when the operating lever 553 is operated to switch between the forward state and the reverse state, determine whether to respond to the forward gear or reverse gear signal output by the operating lever 553 based on the obtained device parameters. The above-mentioned device parameters include the driving speed of the riding lawn mower device 100, the state of the throttle assembly, or the duration after the operating lever 553 is operated to the neutral position. Specifically, the main control circuit 592 is configured to obtain the driving speed during the riding lawn mower device 100 and when the operating lever 553 is operated to switch between the forward state and the reverse state, determine whether to respond to the forward gear or reverse gear signal output by the operating lever 553 based on the obtained driving speed. When the obtained walking speed is less than or equal to the first speed threshold, the forward gear or reverse gear signal output by the operating lever 553 is not responded. It can be understood that when the obtained walking speed is less than or equal to the first speed threshold, the riding lawn mower device 100 is controlled to stop driving. The first speed threshold is greater than or equal to 0.2 km/h and less than or equal to 0.4 km/h. In some embodiments, the first speed threshold is set to 0.3 km/h. It should be noted that in this embodiment, when the main control circuit 952 controls the riding lawn mowing device 100 to stop traveling, the user cannot start the travel motor 933 by stepping on the throttle assembly. In order to restart the travel motor 933, the user needs to first operate the brake assembly 592 to switch the main control circuit to the second state, and then trigger the throttle assembly 591 to start the travel motor.

In some embodiments, the main control circuit is configured to obtain the equipment parameters of the riding lawn mower 100 during driving, and when the operating lever 553 is operated to the neutral position, the riding lawn mower stops driving based on the obtained equipment parameters. The above equipment parameters include the driving speed of the riding lawn mower 100, the state of the throttle assembly, or the duration after the operating lever 553 is operated to the neutral position. Specifically, when the riding lawn mower 100 is in driving, the main control circuit is configured to obtain the duration after the operating lever 553 is switched to the neutral position, and when the above duration is greater than or equal to the first time threshold, the riding lawn mower 100 is controlled to stop driving. In some embodiments, the first time threshold is greater than or equal to 2s. It should be noted that in some of the above embodiments, regarding controlling the riding lawn mower to stop driving, it can be understood that the main control circuit stops driving the travel motor, and of course it can also be understood that the main control circuit controls the travel motor to be in an electronic parking state. Of course, in some embodiments, a clutch structure is provided between the travel motor and the travel wheel, and the clutch structure provided between the travel motor and the travel wheel prevents the rotation speed of the travel motor from being transmitted to the travel wheel, thereby stopping the riding lawn mower.

Next, the control method of the main control circuit 952 controlling the riding lawn mower 100 to move forward or backward is described in conjunction with FIG. 8 . The specific steps are as follows:

S40: The travel motor starts running.

The main control circuit controls the travel motor to operate, thereby driving the riding lawn mowing equipment to move forward or backward on the ground.

S41: Determine whether the gear position is switched to neutral. If yes, execute step S42; if no, execute step S41.

S42: Determine whether the travel speed of the riding lawn mower is less than or equal to a first speed threshold. If yes, execute step S49; if no, execute step S43.

In the present application, when the operating lever 553 is set to neutral, the main control circuit will control the travel motor to slow down or stop driving the travel motor. If the user is in neutral for a long time, the speed of the travel motor will gradually decrease to 0.

S43: Determine whether the current gear is a forward gear. If yes, execute step S44; if no, execute step S46.

In the present application, when the user needs to switch forward or backward, the user needs to first operate the operating lever 553 to the neutral position, and then operate the operating lever 553 to the forward position or the reverse position.

S44: The main control circuit controls the display screen to display the "D" icon and the buzzer sounds to remind that the gear position has been successfully set.

S45: The main control circuit controls the travel motor to decelerate to 0, and then controls the travel motor to rotate forward. Return to step S41.

In the present application, the travel motor rotates forward and drives the riding lawn mowing device forward.

S46: Determine whether the current gear is the reverse gear. If yes, execute step S47; if no, execute step S42.

S47: The "R" icon appears on the main control circuit control display screen and the buzzer sounds to remind that the gear has been set successfully.

S48: After the main control circuit controls the travel motor to decelerate to 0, it controls the travel motor to reverse, and returns to step S41.

In the present application, the reverse rotation of the travel motor means that the riding lawn mower moves backward.

It should be noted that the buzzer in the present application is arranged on the operating component 50, so that it is closer to the user and it is easier to obtain the sound it makes. Specifically, the buzzer can be set on the control panel 52 or the steering wheel component 56. In some embodiments, when the walking error code or the mowing error code of the riding lawn mower is successfully cleared, the buzzer will also emit a prompt sound. In some embodiments, when the riding lawn mower is on a slope and slips, the buzzer will also emit a prompt sound to remind the user. In short, a buzzer is set on the riding lawn mower to provide a prompt for the completion of the operation command or to provide a prompt when a fault occurs or is about to occur.

In this way, by setting an operating lever 553 with three gears, the user can switch between forward and reverse gears without releasing the throttle assembly. On the other hand, it can also actively determine whether the current user intends to park or switch the driving gear, thereby improving the user's sense of use. Of course, when the user manipulates the operating lever 553 to switch between the forward state and the reverse state, the throttle assembly can be released, or the throttle assembly can be triggered all the time, and of course the throttle assembly can be released and triggered again. Of course, after the gear is successfully switched, the speed of the travel motor is set according to the current state of the throttle assembly.

In some embodiments, the riding lawn mower 100 also has a preset mode. The preset mode is a default working mode that cannot be changed by the user. In the preset mode, the travel motor 933 can still work to ensure that the riding lawn mower 100 can be driven home or repaired at an after-sales station.

Specifically, the main control circuit 952 is configured to control the riding lawn mower 100 to enter a preset mode when a preset failure signal is obtained. In the preset mode, the travel motor 933 can drive the riding lawn mower 100 to travel. In some embodiments, the preset failure signal includes that there is no signal transmission between the signal circuit 951 and the display circuit 953 within a preset time. The preset failure signal also includes that there is no signal transmission between the main control circuit 952 and the signal circuit 951 within a preset time. From the perspective of safety and energy saving, when the riding lawn mower 100 enters the preset mode, the lawn mower motor 13 is prohibited from starting. In some embodiments, in the preset mode, the main control circuit 952 controls the maximum speed of the travel motor 933 to be less than or equal to 1100 rpm. In some embodiments, in the preset mode, the main control circuit 952 controls the maximum speed of the travel motor 933 to be less than or equal to 900 rpm. In some embodiments, in the preset mode, the main control circuit 952 controls the speed of the travel motor 933 to be a preset first speed. Among them, the first speed is a preset fixed value, that is, in the preset mode, the user is prohibited from adjusting the travel speed of the riding lawn mower. In some embodiments, in a preset mode, the main control circuit 952 prohibits responding to at least part of the signal output by the operating component 50. For example, the running gear information, the key information, and the start button information. Of course, those skilled in the art can also set other prohibition corresponding signals.

In some embodiments, the main control circuit is configured to control the travel motor and the mowing motor to shut down when a preset failure signal is obtained; after obtaining a restart signal of the riding mowing device and obtaining a preset failure signal again, the riding mowing device is controlled to enter a preset mode.

In some embodiments, the riding lawn mower 100 also has a function of mowing in reverse. In other words, when the riding lawn mower 100 is in the process of moving backward, the main control circuit 952 can control the lawn mower motor 13 to rotate, thereby realizing the function of mowing in reverse. Specifically, the riding lawn mower 100 has a first mode in which mowing in reverse is prohibited and a second mode in which mowing in reverse is allowed. When the display screen 51 of the riding lawn mower 100 enters the second display interface, that is, the power-on interface, it automatically enters the first mode in which mowing in reverse is prohibited. In this way, it can be prevented that the user starts the lawn mower motor 13 during the reverse driving process due to misoperation. At this time, the icon for mowing in reverse on the second display interface is lit.

Specifically, the riding lawn mower 100 further includes a fifth button 516. When the fifth button 516 is pressed, the main control circuit 952 allows the lawn mower motor 13 to start, that is, the riding lawn mower 100 operates in the second mode of allowing lawn mowing in reverse, and the icon of prohibiting lawn mowing in reverse on the first display interface 511 disappears. When the user presses the PTO switch, the lawn mower motor 13 starts, and the lawn mower element 12 starts to rotate to perform the lawn mowing operation. When the riding lawn mower 100 is performing the lawn mowing in reverse, if the operator presses the fifth button 516 again, the main control circuit 952 prohibits the lawn mower motor 13 from starting, that is, the riding lawn mower 100 operates in the second mode of prohibiting lawn mowing in reverse. The icon of prohibiting lawn mowing in reverse on the first display interface 511 is lit. At this time, the lawn mower motor 13 stops, so that the lawn mower element 23 stops rotating. The advantage of this is that the user can conveniently start the reverse mowing function of the riding lawn mower 100, and can also quickly end the reverse mowing function of the riding lawn mower 100. The purpose of this setting is to meet the user's various mowing needs and ensure the safety of the user when starting the reverse mowing function.

In some embodiments, the state of the fifth button 516 matches the icon of the reverse mowing prohibition on the second display interface. Under normal circumstances, the icon of the reverse mowing prohibition on the second display interface is lit, and the riding mowing device 100 works in the first mode of the reverse mowing prohibition. When the user triggers the fifth button 516, the icon of the reverse mowing prohibition on the second display interface disappears, and the riding mowing device 100 works in the second mode of the reverse mowing permission. When the user triggers the fifth button 516 again, the icon of the reverse mowing prohibition on the second display interface is lit again, and the riding mowing device 100 works in the first mode of the reverse mowing prohibition. In this way, the operator can choose whether to start or turn off the reverse mowing function of the riding mowing device through the fifth button 516. On the other hand, the operator can also judge whether the riding mowing device 100 is currently working in the first mode of the reverse mowing prohibition or the second mode of the reverse mowing permission through the state of the icon of the reverse mowing prohibition on the second display interface.

In some embodiments, when the riding lawn mower 100 exits the power-on interface, the main control circuit 592 controls the riding lawn mower 100 to enter the first mode in which mowing is prohibited in reverse. When the user needs to execute the function of mowing in reverse, the fifth button 516 is triggered again to enter the second mode in which mowing is allowed in reverse.
