Description

Multi-functional vehicles, gardening vehicles and electric ride-on lawnmowers Technical Field

[0001] This specification relates to the field of electric engineering vehicle technology, and in particular to a garden operation vehicle, an electric ride-on lawnmower and its charging management method. Background Technology

[0002] With the widespread use of smartphones, the variety of devices waiting to be charged is also increasing, and the charging issues of these devices are attracting more and more attention. Charging power is getting higher and higher, charging time is getting shorter and shorter, and charging technology is becoming more and more mature. From wired fast charging to wireless fast charging, from relying on adapters to now having USB charging ports everywhere, people only need to carry a data cable to easily charge their devices.

[0003] In this context, power supply modules have become standard equipment on many electric devices, such as cars which typically have multiple charging ports for users to charge their devices. However, for gardening vehicles, such as ride-on lawnmowers, mowing is their primary function and takes the highest priority in power usage; the power supply module is merely an additional function. In other words, the power supply of a ride-on lawnmower should prioritize normal mowing work, and only when there is a power reserve should it be used to power other mobile devices. Therefore, when multiple devices need charging, the ride-on lawnmower needs to manage the charging of these devices, and if necessary, set charging permissions to power only designated devices, achieving the effect of "using resources wisely." However, current gardening vehicles do not specify whether they can power users' devices waiting to be charged, or what amount of power can be supplied to these devices. As a result, vehicles that should be able to complete gardening tasks may be unable to complete their tasks due to excessive power supply to other devices waiting to be charged.

[0062] Existing multi-purpose vehicles, when providing charging services to devices, excessively discharge themselves, preventing the multi-purpose vehicles from completing their own tasks. Furthermore, when multi-purpose vehicles are parked, unauthorized users may connect devices to them, causing excessive discharge and preventing the vehicles from completing their assigned tasks.

[0063] In order to avoid the above problems, at least one embodiment of this specification describes a garden operation vehicle 100.

[0064] Referring to Figures 1 and 6, the multi-functional vehicle 100 specifically includes a vehicle body 10, a running gear 20, a dischargeable unit 30, and a charging management unit 40.

[0065] The vehicle body 10 is configured to extend a predetermined distance along the travel direction of the multi-functional vehicle to form a load-bearing component. The walking mechanism 20 is disposed at the bottom of the vehicle body 10 so that the vehicle body 10 can move through the walking mechanism 20. In some embodiments, the walking mechanism 20 includes at least one walking wheel.

[0066] The walking drive component 20 is used to enable the multi-functional vehicle to travel in landscape settings such as lawns, gardens, and fences.

[0067] In one embodiment, the driving assembly 20 includes at least driving wheel elements and driving motors for driving the driving wheel elements. Multiple driving wheel elements may be provided, and the number of driving motors corresponds to the number of driving wheel elements. In other optional embodiments, the driving assembly 20 includes a first driving wheel and a second driving wheel, and two corresponding driving motors. When the two driving motors drive the corresponding driving wheels to rotate at different power levels, a speed difference is generated between the first driving wheel and the second driving wheel, thereby enabling the multi-functional vehicle to steer. In some embodiments, the driving assembly 50 further includes a driving control unit for controlling the driving motors.

[0068] In a preferred embodiment, the multi-functional vehicle 100 includes a working mechanism 50 for gardening operations, thereby enabling the multi-functional vehicle 100 to be implemented as a gardening operation vehicle.

[0069] The working mechanism 50 is implemented as including a mowing element that performs the mowing function. The working mechanism 50 is also connected to the vehicle body 10. The working mechanism 50 also includes a first drive motor for driving the mowing element to rotate at high speed, and a control module for controlling the first drive motor.

[0070] It is worth mentioning that the operating mechanism 50 may include more than one mowing element, and correspondingly, the number of the first drive motors may correspond to the number of mowing elements. For example, in some embodiments, the mowing element has three blades, and the corresponding number of the first drive motors is also set to three. In some specific embodiments, the control module corresponding to the first drive motor includes a control chip, such as an MCU or ARM.

[0071] In some alternative embodiments, the working mechanism 50 is a cleaning element for providing cleaning power. The working mechanism 50 also includes a control module for driving a first drive motor of the cleaning element and controlling the first drive motor.

[0072] It is understood that in some alternative embodiments, the working mechanism 50 can be replaced with other functional components, such as snow sweeping, snow blowing, snow shoveling, and flushing components. Those skilled in the art should be able to adapt and replace various functional components without creative effort. All of the above are within the protection scope of this embodiment, and this application is not limited in this respect.

[0073] The dischargeable unit 30 is disposed on the vehicle body 10. Preferably, the dischargeable unit 30 is detachably mounted on the vehicle body 10, and the dischargeable unit 30 includes a battery compartment in which multiple battery packs 31 can be detachably connected and installed. The battery packs 31 can be easily removed and installed without tools. Those skilled in the art will understand that the multiple battery packs 31 can also be fixedly packaged on the vehicle body 10.

[0074] The plurality of battery packs 31 may be selected from at least one of a first-specification battery pack and a second-specification battery pack. The differences in specifications between the first-specification battery pack and the second-specification battery pack include, but are not limited to, differences in battery pack capacity, voltage, battery internal resistance, weight, size, energy density, cell type, charge information, and battery health status information.

[0075] In some alternative embodiments, the difference between the first-specification battery pack and the second-specification battery pack lies in their battery pack capacities. The capacity of the first-specification battery pack is greater than that of the second-specification battery pack. In some alternative embodiments, corresponding to the capacity difference, the size of the first-specification battery pack is also larger than that of the second-specification battery pack.

[0076] The first-specification battery pack can be used to power large electrical equipment, such as large electric chainsaws, large electric angle grinders, push lawnmowers, smart lawnmowers, push snow sweepers, self-propelled snow sweepers, high-power electric hammers, high-power electric picks, high-power circular saws, high-power concrete cutters, electric bicycles, electric motorcycles, high-power air compressors, and high-power cleaning machines. The first-specification battery pack can also be used as an energy storage device to power other electrical equipment or to charge other battery packs.

[0077] The second-specification battery pack is configured to power handheld garden tools. For example, it can power garden tools such as lawn mowers, pruning shears, hair dryers, and chainsaws. Furthermore, it can power torque-output tools such as drills and hammer drills; sawing tools such as circular saws, jigsaws, and reciprocating saws; or grinding tools such as angle grinders and sanders.

[0078] In some alternative embodiments, the difference between the first-specification battery pack and the second-specification battery pack lies in the type of battery cells used. For example, the first-specification battery pack and the second-specification battery pack can respectively use lithium iron phosphate cells and ternary lithium cells. The plurality of battery packs 31 can also use nickel-cadmium battery cells, lead-acid battery cells, graphene cells, etc.

[0079] Multiple battery packs 31 are selected from at least one of the first specification battery pack and the second specification battery pack. This method allows the multi-functional vehicle to be compatible with battery packs of different specifications, meeting the needs of high-power operation while also being compatible with handheld electric garden tools, making the work of garden workers more flexible.

[0080] Preferably, the multi-functional vehicle 100 further includes an operating mechanism 60, wherein the walking mechanism 20 is drivably connected to the operating mechanism 60 so that it can be driven by the operating mechanism 60 to move the vehicle body 10.

[0081] The dischargeable unit 30 further includes at least one discharge terminal 32, wherein the discharge terminal 32 is electrically connected to the battery pack 31 so that the battery pack 31 can discharge through the discharge terminal 32. The battery pack 31 is disposed on the vehicle body 10. In a preferred embodiment, the operating mechanism 60 is implemented as a motor, wherein the battery pack 31 is electrically connected to the operating mechanism 60 to supply power to the operating mechanism 60. In one embodiment, the operating mechanism 60 is implemented as a motor.

[0082] Referring to Figure 11, the charging management unit 40 includes a charging trigger 41 and a controller 42. The charging management unit 40 is electrically connected to the battery pack 31 and the discharge terminal 32.

[0083] The charging trigger 41 is configured to receive and collect request signals related to requesting the battery pack 31 to discharge for at least one device 900 to be charged, wherein the device 900 to be charged is electrically connected to the charging interface of the discharge terminal 32. For example, in one embodiment, when the charging interface of the discharge terminal 32 is connected to the device 900 to be charged, the electrical parameters of the circuit in the battery pack 31, such as current and / or resistance and / or voltage, change, thereby generating the request signal. The charging trigger 41 can receive the request signal. In this example, the charging trigger 41 is configured as an electrical signal sensor including an electrical parameter detection circuit, such as a current sensor, voltage sensor, resistance sensor, etc. In this way, the discharge terminal 32 can be effectively prevented from discharging without the device 900 to be charged being connected.

[0084] For example, in another embodiment, when the charging interface of the discharge terminal 32 is connected to the device 900 to be charged, and the charging trigger 41 responds to a user's request to confirm charging of the device 900, a request signal will be generated. In this embodiment, the charging trigger 41 may be configured to include a remote feedback component, such as, but not limited to, a Bluetooth module.

[0085] The controller 42 is communicatively connected to the charging trigger 41 and determines the output capacity available to charge the device to be charged based on the received request signal, the current remaining charge of the battery pack 31, and the required charge level, wherein the required charge level is the minimum charge level required for the multi-functional vehicle to perform a predetermined workload; and adjusts the battery pack to charge the device to be charged 900 based on the output capacity. Those skilled in the art will understand that this configuration ensures that the multi-functional vehicle can only charge the device to be charged 900 with user confirmation, thereby effectively guaranteeing the vehicle's battery capacity to some extent.

[0086] In a preferred embodiment, the required reserve of battery power can be preset, for example, set to 30%, 40%, or 50% of the total battery power limit. Those skilled in the art will understand that the required reserve of battery power can be customized by the staff / user based on the actual working conditions in the application scenario. After the user customizes the required reserve of battery power, the multi-functional vehicle will reserve the corresponding remaining battery power, allowing the user to retain the battery power of the multi-functional vehicle according to their own needs.

[0087] In some optional embodiments, the required reserve power can also be set based on the working time of the multi-functional vehicle / garden operation vehicle after it has been turned on, with the required reserve power gradually decreasing as the working time increases. For example, at the beginning of operation, when the working time is zero, the required reserve power is 60% of the maximum total power; when the working time increases to 1 hour, the required reserve power decreases to 45% of the maximum total power; when the working time increases to 2 hours, the required reserve power decreases to 30% of the maximum total power.

[0088] Those skilled in the art will understand that when the multi-functional vehicle 100 is performing gardening operations, the electrical energy stored in the battery pack 31 of the multi-functional vehicle 100 should be preferentially supplied to the multi-functional vehicle 100.

[0089] By controlling the battery pack to charge the device 900 based on the output power, the controller 42 can effectively ensure the normal operation of the multi-functional vehicle 100 while also charging the device 900 as much as possible.

[0090] Specifically, in one example, the multi-functional vehicle 100 determines the required battery power by the following method: First, the power consumption required for operation per unit area by the multi-functional vehicle 100 and the remaining area to be operated by the multi-functional vehicle 100 are considered. The required battery power is then determined by multiplying the power consumption required for operation per unit area by the remaining area to be operated by the multi-functional vehicle 100. It is understood that the power consumption required for operation per unit area by the multi-functional vehicle 100 can be pre-stored in the controller 42 using empirical values, and the area already completed by the multi-functional vehicle 100 can be obtained by monitoring the completed work area. Furthermore, the total area to be completed can also be pre-stored in the controller 42. In this way, the required battery power of the multi-functional vehicle 100 can be determined.

[0091] In another embodiment, the multi-functional vehicle 100 should maintain the following battery level: Where h and m represent the specific grass height and grass density, respectively, δ and ε represent the adjustment coefficients corresponding to the height and density, respectively; E represents the power consumption required for mowing per unit area based on the preset standard height H and standard density M.

[0092] In another embodiment, the power consumption per unit area required for the multi-functional vehicle 100 to operate in the current work area most recently, as well as the remaining work area of ​​the multi-functional vehicle 100, can also be determined, thereby enabling the multi-functional vehicle to maintain sufficient power.

[0093] Those skilled in the art will understand that the minimum remaining battery power of the multi-functional vehicle 100 can be determined through the above method.

[0094] In one embodiment, the working mechanism 50 is provided with a water spraying component including a pump body and a water spraying element. The dischargeable unit 30 is electrically connected to the working mechanism 50 to supply power to the pump body in the working mechanism 50.

[0095] Preferably, in one embodiment, the working mechanism 50 in the gardening vehicle is implemented to include a mowing element for mowing, a first drive motor for driving the mowing element to rotate at high speed, and a control module for controlling the first drive motor, thereby defining it as a ride-on lawnmower, wherein the working mechanism 50 in the ride-on lawnmower includes...

[0096] Preferably, the ride-on lawnmower further includes an operating component 700, wherein the operating component 700 is electrically connected to the battery pack 31 of the dischargeable unit 30 and coupled to the operating mechanism 60, wherein after the user operates the operating component 700, the controller 42 generates a corresponding operating signal to control the operating mechanism 60 to drive the walking mechanism 20 to perform walking actions.

[0097] Referring more specifically to Figures 2 to 6, the operating component 700 includes a left operating lever 710, a right operating lever 720, a left sensor 730, and a right sensor 740, wherein the left sensor 730 and the right sensor 740 are communicatively connected to the controller 42. The left sensor 730 is configured to detect the state of the left operating lever 710 after it has been operated and generate a corresponding operating signal, while the right sensor 740 is configured to detect the state of the right operating lever 720 after it has been operated and generate a corresponding operating signal. The controller 42 controls the operating mechanism 60 to operate according to the operating signals. In this example, the operating mechanism 60 includes a left drive motor 61 and a right drive motor 62, wherein the walking mechanism 20 includes a left wheel 21 and a right wheel 22 symmetrically arranged with respect to the left wheel 21, wherein the left wheel 21 and the right wheel 22 are rotatably connected to the left drive motor 61 and the right drive motor 62, respectively, and wherein the left drive motor 61 and the right drive motor 62 are controllably connected to the controller 42. Therefore, when the user operates the left control lever 710 and the right control lever 720, the controller 42 can adjust the left drive motor 61 and the right drive motor 62 accordingly based on the operation signals generated by the left sensor 730 and the right sensor 740, thereby coordinating the left drive wheel and the right drive wheel to drive the vehicle body 10 to move.

[0098] Specifically, the battery pack 31 is configured to include at least one battery pack, preferably multiple battery packs. In one embodiment, the multiple battery packs are of the same model, while in another embodiment, at least two of the multiple battery packs are of different models. It is worth mentioning that the different battery packs have different rated power and discharge rates.

[0099] It is worth mentioning that, in one embodiment, the discharge terminal 32 includes an interface that matches the device to be charged 900, such as at least two or more interfaces selected from Micro USB interface, USB Type C interface, and Lightning interface. Preferably, the discharge terminal 32 includes Micro USB interface, USB Type C interface, and Lightning interface simultaneously.

[0100] Those skilled in the art will understand that the number of Micro USB interfaces and / or USB Type C interfaces and / or Lightning interfaces is optional. This embodiment only illustrates the example of the discharge terminal 32 including one Micro USB interface and / or USB Type C interface and / or Lightning interface, which does not limit this specification. Similarly, this embodiment only illustrates the example of the discharge terminal 32 simultaneously including a Micro USB interface, a USB Type C interface, and a Lightning interface, which does not limit this specification. As a variation, the discharge terminal 32 may also be provided with a wireless charging component, such as a wireless discharge coil and a frequency conversion circuit, so that the device 900 to be charged with wireless charging function can also be wirelessly charged at the discharge terminal 32.

[0101] The interface can be located on the vehicle body 10 and / or the operating component 700, etc.

[0102] For example, in one embodiment, the interface may be located on the multi-function handle of the multi-function vehicle, such as at the end of the multi-function handle or on the button panel of the multi-function handle.

[0103] In another example, as shown in Figure 5A, which is an enlarged schematic diagram of part A of the structure shown in Figure 2, the interface can also be located on the seat armrest of the vehicle body 10 of the multi-functional vehicle. In yet another embodiment, the interface can also be located on the display component of the multi-functional vehicle, which is mounted on the vehicle body 10.

[0104] In another embodiment, the interface may also be located at other locations on the vehicle body 10. This application is not limited in this respect.

[0105] Especially when the gardening vehicle is implemented as a ride-on lawnmower, as a variation, the interface can also be located in other positions on the vehicle body 10, as shown in Figures 5B and 5C. For example, in one example, the vehicle body 10 is provided with covers, such as the left cover 12 and / or the right cover 13. The interface can be located on the operating plane formed by the upper part of the left cover 12 and / or the right cover 13. This operating plane is typically provided with a power key switch, a cutter switch, a cutter head adjustment assembly, etc.

[0106] In another embodiment, the vehicle body 10 further forms at least one storage space, to which the left cover 12 is concealed. For example, the interface may be located within the storage space covered by the left cover, such as at the bottom or on the inner wall of the storage space.

[0107] Furthermore, the controller 42 is configured to receive the ID of the device to be charged 900 obtained by the charging trigger 41, and verify whether the ID of the device to be charged 900 and the ID of the multi-functional vehicle are associated. If they are, the controller outputs a verification result, and the controller 42 continues to determine the output power of the device to be charged, as shown in Figure 7. If not, the controller 42 regulates the battery pack 31 to prevent the battery pack 31 from charging the device to be charged 900, so that the output power is 0.

[0108] It is worth mentioning that when a user purchases the multi-functional vehicle 100, the multi-functional vehicle 100 has a unique ID. The device 900 to be charged also has its own ID. To ensure that the power of the multi-functional vehicle 100 can be used for its operation and to set charging permissions for the user, the device 900 to be charged can be pre-associated with the multi-functional vehicle 100. After any device 900 to be charged is connected to the interface of the discharge terminal 32, the controller 42 can verify whether the ID of the device 900 to be charged and the ID of the multi-functional vehicle are associated. If they are, the controller 42 outputs a verification result, and the controller 42 continues to determine the output power that the device 900 to be charged can handle. If not, the controller 42 regulates the battery pack 31 to prevent the battery pack 31 from charging the device 900 to be charged.

[0109] In other words, only when the device to be charged 900 is associated with the multi-functional vehicle 900 does it have the authority to replenish power from the battery pack 31 of the multi-functional vehicle 100. If the device to be charged 900 is not associated with the multi-functional vehicle 900, it does not have the authority to replenish power from the battery pack 31 of the multi-functional vehicle 100. In this way, the remaining power of the battery pack 31 of the multi-functional vehicle 100 can be effectively guaranteed, thereby ensuring that the multi-functional vehicle 100 has sufficient power to operate.

[0110] Those skilled in the art will understand that, in one example, the device to be charged 900 and the multi-functional vehicle 900 are associated. In another embodiment, the charging management unit 40 includes an information acquisition circuit 43, which is communicatively connected to the controller 42. The information acquisition circuit 43 is configured to be electrically connected to the device to be charged 900 simultaneously with the interface 32, and to acquire the ID of the device to be charged 900. This allows the controller 42 to subsequently compare the acquired ID of the device to be charged 900 with the ID of the multi-functional vehicle 100.

[0111] In a preferred embodiment, the charging management unit 40 includes at least one feedback component 44, wherein the feedback component 44 is communicatively connected to the controller 42.

[0112] Referring to Figures 8A and 8B, when the interface of the discharge terminal 32 is electrically connected to the device 900 to be charged, the charging trigger 41 receives the request signal, and the feedback component 44 is configured to generate a feedback signal in response to the request signal. This feedback signal correspondingly prompts the user whether they are certain they wish to charge the device 900. In other words, the feedback component 44 is configured to generate a corresponding confirmation signal in response to the user's confirmation or denial of charging the device 900. Accordingly, when the feedback component 44 generates a confirmation signal confirming that the device 900 is being charged, the controller 42 outputs a verification result based on the confirmation signal received by the charging trigger 41. The verification result allows the controller 42 to further determine the output capacity that can be charged the device. Conversely, when the feedback component 44 generates a confirmation signal denying that the device 900 is being charged, the controller 42 outputs a verification result denying the confirmation. Based on the failure result, the controller 42 adjusts the battery pack 31 to prevent the battery pack 31 from charging the device 900 to be charged.

[0113] It is worth mentioning that, in one embodiment, the feedback component 44 is integrated into a display screen, wherein the feedback component 44 can interact with the user to determine whether to charge the device 900 currently being charged. In another embodiment, the feedback component 44 includes a component with a communication function module, such as a Bluetooth module, a WiFi module, a LiFi module, a Zigbee module, etc.

[0114] Referring to Figures 2 and 9, in a preferred embodiment, the discharge terminal 32 is provided with at least two interfaces, wherein the two interfaces are a first interface 3201 and a second interface 3202. The controller 42 is configured to determine whether the first interface 3201 and the second interface 3202 are simultaneously connected to a device 900 to be charged. When both the first interface 3201 and the second interface 3202 are connected to devices 900 to be charged, the controller 42 determines the charging order of one device 900 connected to the first interface 3201 and another device 900 connected to the second interface 3202 according to a preset charging priority of the first interface 3201 and the second interface 3202. Based on the charging order determined by the controller 42, the controller 42 can charge one device 900 connected to the first interface 3201 and another device 900 connected to the second interface 3202 sequentially.

[0115] Referring to Figures 2 and 9, in a preferred embodiment, at least one first charging interface 321 and one second charging interface 322 are formed on the vehicle body 10 at the discharge end 32 where the interfaces are provided. The first charging interface 321 has a preset first charging priority, and the second charging interface 322 has a preset second charging priority. For example, the charging sequence of the first charging interface 321 with the first charging priority takes precedence over the charging sequence of the second charging interface 322 with the second charging priority. Both the first charging interface 321 and the second charging interface 322 are provided with at least one interface for connecting the device 900 to be charged.

[0116] In one embodiment, the first charging port 321 is used to charge devices with a power output below a preset threshold, such as mobile phones and tablets, while the second charging port 322 is used to charge devices with a power output above a preset threshold, such as handheld chainsaws and hair dryers. In this way, when a user needs to charge the device 900, they can selectively use the first charging port 321 and / or the second charging port 322 to charge the device 900 based on its own charging power, thus preventing overloading of the device 900 and reducing its lifespan.

[0117] In this embodiment, when one device 900 to be charged is connected to the interface of the first charging interface 321 and the other device 900 to be charged is connected to the interface of the second charging interface 322, the charging trigger 41 can receive the collected electrical parameters of the two devices 900 to be charged, and the controller 42 can determine whether the device 900 to be charged is located in the correct charging area based on the electrical parameters of the device 900 to be charged. If either device 900 to be charged is located in the wrong charging area, the controller 42 generates a corresponding prompt signal based on the judgment result formed by the controller 42.

[0118] The alert signal corresponds to at least one or more of the following signals, including but not limited to: alarms, flashing lights, etc.

[0119] It is worth mentioning that, in another embodiment, the charging management unit further includes a positioning module 45, wherein the positioning module 45 is communicatively connected to the controller 42, and the positioning module 45 is configured to collect the current location of multiple multi-functional vehicles 100, wherein the IDs of multiple multi-functional vehicles 100 are simultaneously associated with the same ID of the device to be charged.

[0120] It is also worth mentioning that when the device 900 to be charged is electrically connected to the interface on a multi-functional vehicle 100, the controller 42 controls the battery pack 31 to charge the device 900 according to the corresponding request signal. The controller 42 can determine whether the battery pack 31 of the multi-functional vehicle 100 has sufficient charge to meet the charging amount required by the request signal. If so, the controller 42 controls the multi-functional vehicle 100 to charge the device 900. Conversely, if not, the controller 42 will recommend other multi-functional vehicles 100 associated with the same device ID to be charged based on the positioning data obtained by the positioning module 45. The recommended multi-functional vehicles 100 are within a predetermined distance from the multi-functional vehicle 100 charging the device 900 and meet the charging amount requirements corresponding to the request signal.

[0121] In this way, the user can charge the device 900 by using other multi-functional vehicles 100 with IDs associated with the same device 900 recommended by the controller 42. Those skilled in the art will understand that these multi-functional vehicles typically operate outdoors. Normally, when the user's device 900 needs charging outdoors, it either needs to be charged by one of the multi-powered vehicles 100. If the multi-powered vehicle 100 lacks sufficient power, the user often has to return or have another user transport the battery pack for charging. However, through the implementation of the above embodiment, the user can accurately identify other multi-functional vehicles 100 in the vicinity authorized to charge the device 900. This effectively meets the user's charging needs while allowing them to obtain power nearby, provided that other multi-functional vehicles 100 are operating normally.

[0122] As shown in Figure 10, the IDs of one multi-functional vehicle 100A and another multi-functional vehicle 100B are simultaneously associated with the same user, and the ID of the device to be charged 900 is also simultaneously associated with the same user as both multi-functional vehicle 100A and the other multi-functional vehicle 100B. When the device to be charged 900 is electrically connected to the interface on one of the multi-functional vehicles 100, since the multi-functional vehicle 100A cannot meet the charging requirements of the device to be charged 900, the controller 42 will determine, based on the positioning data obtained by the positioning module 45, that the multi-functional vehicle 100B meets the charging requirements of the device to be charged 900, and will recommend the multi-functional vehicle 100B to the user. In this way, not only can the remaining power of the battery pack 31 on the multi-functional vehicle 100A be effectively guaranteed to complete subsequent landscaping work, but the device to be charged 900 can also be charged as quickly as possible.
