[0042] Reference Figure 1 The lawn mower 100 shown mainly includes a handle device 11, a connecting rod 111, an operating member 112, an operating switch 112a, a main unit 12, and a travel assembly 121. The main unit 12 includes a travel assembly 121 and a power mechanism (not shown). Optionally, the handle device 11 includes a connecting rod 111 and an operating member 112 that can be held. The operating member 112 at least includes a grip for the user to hold and a self-propelled operating trigger 112a; the connecting rod 111 is a hollow long rod structure, and the connecting rod 111 connects the operating member 112 and the main unit 12. The travel assembly 121 is installed on the main unit 12, and the travel assembly 121 can rotate around a rotation axis so that the entire lawn mower 100 can move on the ground. In this embodiment, the travel assembly 121 includes a travel wheel 1211 of the lawn mower 100 and a power mechanism that drives the travel wheel 1211 to travel.

[0043] In this embodiment, the lawn mower 100 has a self-propelled control function, and the power mechanism can drive the walking component 121 to rotate, thereby driving the lawn mower 100 to move on the ground, so that the user does not need to manually push the lawn mower 100 to move and cut grass. The power mechanism can specifically be a walking motor, and the walking motor can output a driving force to drive the walking component 121 to rotate. In some embodiments, a mowing operation trigger 112b is also integrated on the handle device 11 of the lawn mower 100. Exemplarily, the mowing operation trigger 112b and the self-propelled operation trigger 112a of the lawn mower 100 are both integrated on the operating member 112. In addition, the operating switch 112a is not limited to a physical switch or a signal switch, and any device that can control the opening and closing of the current in the circuit is applicable. In fact, the above-mentioned self-propelled operation trigger 112a and / or the mowing operation trigger 112b are not limited to the control of the current, and can also be a mechanical means to control the opening or closing of the self-propelled function.

[0044] The host 12 or the handle device 11 may be provided with a main control board 200, and the control circuit 2000 on the main control board 200 can at least control the walking and / or mowing of the lawn mower 100. Figure 2 As shown, the control circuit 2000 may at least include a power interface 20 , a controller 21 , a first drive circuit 22 , a travel motor 23 , a second drive circuit 24 , and a cutting motor 25 .

[0045] Among them, the power interface 20 can be connected to a DC power supply or an AC power supply. The control circuit 2000 may include a circuit capable of converting the connected power supply. For example, the control circuit 2000 may include a rectifier circuit, a filter circuit, or a voltage conversion circuit, etc., which can rectify, filter, or increase / decrease the voltage of the power supply line connected to the power interface 20. It can be understood that the lawn mower 100 may include two or more power interfaces of the same but different types. For example, the lawn mower 100 may include two DC power interfaces, which can be connected to at least two battery packs. In this embodiment, the power interface 20 is used to connect a battery pack 300 for an electric tool. That is, the battery pack 300 can power the lawn mower 100, and can also power a variety of different types of electric tools. Exemplarily, the rated voltage of the battery pack 300 is greater than or equal to 40V, or greater than or equal to 36V, or greater than or equal to 50V, etc. This embodiment does not specifically limit the appearance structure of the battery pack 300.

[0046] In some embodiments, the power tool that can be powered by the battery pack 300 can be a handheld power tool, such as a drill, a pruning machine, a sander, etc. Alternatively, it can also be a bench-type tool, such as a table saw, a miter saw, etc. Alternatively, it can also be a riding power tool, such as a riding lawn mower, a riding vehicle, an all-terrain vehicle, etc. Alternatively, it can also be a robot tool, such as a lawn mowing robot, a snow-clearing robot, etc. In some embodiments, the power tool can also be an electric drill, an electric light, an electric car, etc. In some embodiments, the power tool can also be a garden tool, such as a pruning machine, a hair dryer, a chain saw, etc. Alternatively, the power tool can also be a decoration tool, such as a screwdriver, a nail gun, a circular saw, a sander, etc. In some embodiments, the power tool can also be a vegetation care tool, such as a lawn mower, a pruning machine, a chain saw, etc. Alternatively, the power tool can also be a cleaning tool, such as a hair dryer, a snow sweeper, a cleaning machine, etc. Alternatively, the power tool can also be a drill tool, such as a drill, a screwdriver, a wrench, an electric hammer, etc. Alternatively, the power tool can also be a saw tool, such as a reciprocating saw, a jig saw, a circular saw, etc. Alternatively, the electric tool may be a bench tool, such as a bench saw, a miter saw, a metal cutter, a router, etc. Alternatively, the electric tool may be a grinding tool, such as an angle grinder, a sander, etc. Alternatively, the electric tool may be other tools, such as a lamp, a fan, etc.

[0047] The first drive circuit 22 is connected between the controller 21 and the travel motor 23, and is used to drive the travel motor 23. In one embodiment, the first drive circuit 22 is electrically connected to each phase stator winding of the travel motor 23, and is used to transfer the power supply current to the stator winding to drive the travel motor 23 to rotate. Figure 2 As shown, the first drive circuit 22 includes a plurality of switch elements Q1, Q2, Q3, Q4, Q5, and Q6. Each gate terminal of the switch element is electrically connected to the controller 21 for receiving a control signal from the controller 21. Each drain or source of the switch element is connected to the stator winding of the travel motor 23. The switch elements Q1-Q6 receive control signals from the controller 21 to change their respective conduction states, thereby changing the current loaded by the power supply on the stator winding of the travel motor 23. In one embodiment, the switch elements Q1-Q6 in the first drive circuit 22 can be a three-phase bridge driver circuit including six controllable semiconductor power devices (such as FET, BJT, IGBT, etc.), or any other type of solid-state switch, such as IGBT, BJT, etc.

[0048] The second driving circuit 24 is connected between the controller 21 and the cutting motor 25 to drive the cutting motor 25. The circuit structure and driving mode of the second driving circuit 24 can refer to the circuit structure and driving mode of the first driving circuit 22, which will not be described here.

[0049] The controller 21 can at least detect the operation signal generated after the handle device 11 is operated by the user, and then control the travel motor 23 and / or the cutting motor 25 to operate according to the detected operation signal. Exemplarily, after the user operates the handle device 11 to turn on, the travel motor 23 and / or the cutting motor 25 are powered on, and the controller 21 detects the thrust signal transmitted from the handle device 11, and then controls the travel motor 23 to perform operations such as moving forward, turning, decelerating, or accelerating, or detects a mowing signal, and can control the cutting motor 25 to operate so that the cutting blade cuts the vegetation.

[0050] In one embodiment, the user can start the lawn mower 100 by operating the handle device 11, for example, starting the travel motor 23 to make the lawn mower 100 start moving, or starting the cutting motor 25 to make the lawn mower 100 start mowing, or starting both motors at the same time to make the lawn mower 100 move and mow at the same time. Exemplarily, when the user operates the operating handle 11, a start signal can be generated and transmitted to the controller 21. After the controller 21 recognizes the start signal, it can control the motor to start, wherein the start signal can include a self-propelled start signal and a mowing start signal, and the controller 21 can distinguish different start signals and control different motors to start.

[0051] In the prior art, in order to quickly start the lawn mower, a large starting acceleration is usually set so that the travel motor 23 or the cutting motor 25 can reach the set target speed in a short time. However, if the motor starting acceleration is too fast, the stability of the motor speed increase will be reduced, which will reduce the user's operating feel. If the motor starting acceleration is set too low, the starting process will be slow, which cannot meet the user's demand for quick starting.

[0052] In the embodiment of the present application, the starting acceleration of the lawn mower 100 can be controlled, which can meet the user's demand for quick starting while ensuring the stability of the starting speed.

[0053] In one embodiment, the controller 21 can control the walking motor 23 to accelerate to the target self-propelled speed with a variable self-propelled acceleration in response to the start signal. In one implementation, the variable self-propelled acceleration can have at least one change process. For example, if the initial value of the self-propelled acceleration is a1, the self-propelled acceleration will change once and become a2 during the startup of the self-propelled motor 23, wherein a1 is greater than a2, or a1 is less than a2. In other embodiments, the self-propelled acceleration can have two or more changes. In some embodiments, the change condition of the self-propelled acceleration can be time, or a speed threshold, or a combination of the two. For example, the controller 21 can control the self-propelled acceleration to change once every preset time, or control the self-propelled acceleration to change once when the speed of the walking motor 23 reaches a preset value. In some embodiments, the user can also operate the handle device 11 to change the self-propelled acceleration.

[0054] In one implementation, the variable cutting acceleration may have at least one change process. For example, if the initial value of the self-propelled acceleration is a3, the cutting acceleration may change once and become a4 during the startup of the cutting motor 25. In other embodiments, the cutting acceleration may have two or more changes. In some embodiments, the change condition of the cutting acceleration may be time, or a speed threshold, or a combination of the two. For example, the controller 21 may control the cutting acceleration to change once every preset time, or may control the cutting acceleration to change once when the speed of the cutting motor 25 reaches a preset value. In some embodiments, the user may also operate the handle device 11 to change the cutting acceleration.

[0055] In this embodiment, reference Figure 3 As shown in the speed change curve of the self-propelled motor 23, the controller 21 can control the walking motor 23 to accelerate to the first speed v1 at the first acceleration, and accelerate to the target walking speed v2 based on the first speed at the second acceleration. The first acceleration is greater than the second acceleration. At the initial start-up, the walking motor 23 is started with a faster start-up acceleration, and when the start-up speed reaches a certain value, the speed increase slope is reduced, so that the walking motor 23 can accelerate smoothly at high speed. Figure 4 The speed change curve of the cutting motor 25 shown in FIG. 2 shows that the controller 21 can control the cutting motor 25 to accelerate to the third speed v3 at the third acceleration, and accelerate to the target cutting speed v4 at the fourth acceleration based on the third speed. The third acceleration is greater than the fourth acceleration. In the initial stage of startup, the cutting motor 25 is started with a faster startup acceleration, and when the startup speed reaches a certain value, the slope of the speed increase is reduced, so that the cutting motor 25 can be accelerated smoothly at a high speed, while ensuring the safety of the starting of the cutting motor 25.

[0056] refer to Figure 1 The lawn mower 100 shown in the figure further includes an Internet of Things module 27. The Internet of Things module 27 can be arranged on the main control board 200, or arranged on the handle device 11, or detachably mounted on the lawn mower 100, or at least can communicate with the main control board 200. Figure 5 In the lawn mower system 1000 shown, the lawn mower 100 can communicate with the external terminal 300 through the Internet of Things module 27 and obtain the communication data sent by the external terminal 300.

[0057] In this embodiment, the external terminal 300 can be a smart phone, a smart watch, a tablet computer, a VR / AR device, a drone, etc. This application takes a smart phone as an example for explanation.

[0058] The Internet of Things module 27 can support at least one of wired communication technology and wireless communication technology. In one embodiment, the Internet of Things module 27 supports at least one of transmission access, network switching, mobile communication, wireless communication, optical communication, satellite communication, support management, and private network communication. In one embodiment, the Internet of Things module 27 supports at least one of cellular network technology, wireless local area network technology, wireless personal local area network technology, satellite communication technology, infrared communication technology, optical fiber communication technology, Bluetooth low energy technology, LoRa technology, WiFi, and ZigBee. Among them, the cellular network technology can include, for example, 2G, 3G, 4G, 5G and other mobile communication technologies, as well as standards such as CDMA, GSM, TD-SCDMA, WCDMA, and LTE. Wireless local area network technology can include technologies such as Wi-Fi, Bluetooth, and ZigBee for wireless communication within the scope of the local area network. Wireless personal local area network technology can include technologies such as NFC and RFID for close-range wireless communication. Satellite communication technology can include technologies such as satellite phone, satellite television, and satellite navigation for long-range wireless communication. Infrared communication technology can include technologies such as infrared remote control and infrared data transmission for close-range wireless communication. Optical fiber communication technology can include optical fiber communication, optical fiber sensing and other technologies, which are used for high-speed, long-distance wireless communication. LoRa technology is an ultra-long-distance wireless transmission solution based on spread spectrum technology.

[0059] The user can at least send the startup setting data to the Internet of Things module 27 by operating the smart terminal 300. The controller 21 can communicate with the Internet of Things module 27 to obtain the startup setting data, and at least adjust the self-propelled acceleration and / or the mowing acceleration according to the startup setting data. That is, the startup setting data at least includes setting data for the startup acceleration. In other embodiments, the startup setting data may also include data for setting the startup time, startup mode, startup power, etc.

[0060] In this embodiment, the user can send the startup setting data to the lawn mower 100 before the lawn mower 100 is started, or send the startup setting data to the lawn mower 100 during the startup process of the lawn mower 100. That is, the user can set the startup acceleration according to his / her own usage requirements before the lawn mower 100 walks and / or mows the lawn, or change the startup acceleration during the startup process of the lawn mower 100. For example, during the startup process of the lawn mower 100, if the user perceives that the startup speed of the travel motor 23 is slow, the self-propelled acceleration can be increased through the smart terminal, otherwise the self-propelled acceleration can be reduced.

[0061] In one embodiment, after the intelligent terminal 300 establishes a communication connection with the lawn mower 100, a control interface for the lawn mower 100 can be displayed in the terminal application, or at least a start-up acceleration adjustment interface for different motors can be displayed. Figure 6 As shown, under the icons of the walking motor 23 and the cutting motor 25, there are triangular adjustment buttons for the self-propelled acceleration and the cutting acceleration, respectively. The user can increase or decrease the self-propelled acceleration or the cutting acceleration by touching the adjustment button. In one embodiment, the amplitude of the acceleration adjusted by the adjustment button is fixed, for example, increasing by 1m / s each time. In other embodiments, a user input box can also be directly set in the display interface, and the user can directly enter any starting acceleration value that does not exceed the safety regulations of the lawn mower 100. The smart terminal 300 can also use any other display control interface that is easy to understand and operate, which is not specifically displayed here.

[0062] The controller 21 can adjust the first acceleration of the walking motor 23 at startup according to the acquired startup setting data for the walking motor 23, so that the walking motor 23 can increase to the first speed faster, or can adjust the second acceleration of the walking motor 23, so that the speed increase of the walking motor 23 in the high-speed startup stage is more stable. Alternatively, the controller 21 can also adjust the third acceleration of the cutting motor 25 at startup according to the acquired startup setting data for the cutting motor 25, so that the cutting motor 25 can increase to the third speed faster, or can adjust the fourth acceleration of the cutting motor 25, so that the speed increase of the cutting motor 25 in the high-speed startup stage is more stable.

[0063] In one embodiment, the controller 21 may include at least a data storage unit and a control unit, wherein the data storage unit may acquire and store the startup setting data, and the control unit may be configured to adjust at least the self-propelled acceleration and / or the mowing acceleration according to the startup setting data. In this embodiment, the data storage unit may also store all historical startup setting data, or at least store the historical startup setting data of the last use, and the control unit may set the self-propelled acceleration and / or the mowing acceleration of the lawn mower 100 when it is currently started according to the historical startup setting data. Thus, the user's usage habits can be well preserved, or at least the user's habit of starting the lawn mower 100 can be preserved.

[0064] In other embodiments, the user can also adjust different working parameters of the lawn mower 100 after it is started through the smart terminal 300, for example, the normal walking speed of the lawn mower 100, or the normal mowing speed, or the walking direction, etc., which are not listed here one by one.

[0065] In some embodiments, the user can also reset the functions of some operating components 112 in the lawn mower 100 through the smart terminal 300. For example, the user can redefine the self-propelled operation trigger 112a as the mowing operation trigger 112b, and redefine the mowing operation trigger 112b as the self-propelled operation trigger 112a through the smart terminal 300. In other words, the user can swap the positions of the self-propelled operation group trigger 112a and the mowing operation trigger 112b according to personal usage habits. In some embodiments, a trigger switching mechanism (not shown) can also be provided in the lawn mower 100, and the user can directly operate the trigger switching mechanism to swap the positions of the self-propelled operation trigger 112a and the mowing operation trigger 112b.

[0066] Continue to refer Figure 1 The lawn mower 100 further includes a lighting assembly 122, which includes at least a lighting element 1221 and a lighting switch (not shown) disposed on the handle device 11. The user can control the lighting element 1221 to turn on or off or the lighting brightness by operating the lighting switch. Figure 7 , the lighting element 1221 can be driven by the lighting control circuit 1222, and the lighting control circuit 1222 is arranged on the lighting control circuit board 1223. The lighting control circuit board 1223 can be arranged below the lighting element 1221, or arranged near the lighting element 1221. Bus communication or other communication methods such as carrier communication can be adopted between the lighting control circuit board 1223 and the main control board 200. The control circuit 2000 on the main control board 200 can at least communicate with the lighting control circuit 1222. In this embodiment, by separately arranging the lighting control circuit 1222 on the lighting control circuit board 1223, the heating of the main control board 200 can be reduced.

[0067] In one embodiment, reference Figure 8 At least some components of the light control circuit 1222 are arranged on the main control board 200, and other components are arranged on the light control circuit board 1223. The light control circuit board 1223 can communicate with the main control board 200 through a bus. By reducing the components arranged on the light control circuit board 1223, it is possible to avoid the light control circuit board 1223 being affected by the heat generated by the light of the lighting element 1221 when it is arranged near the lighting element 1221, thereby reducing the service life of some components in the light control circuit 1222.
