Description

A multi-functional vehicle, a gardening vehicle, and a ride-on lawnmower Technical Field

[0001] This manual relates to the field of garden vehicle engineering technology, specifically to a multi-functional vehicle, a garden operation vehicle, and a ride-on lawnmower. Background Technology

[0002] Compared to traditional fuel-powered lawnmowers, rechargeable lawnmowers offer advantages such as all-weather operation with zero emissions, zero fuel consumption, low noise, and simple maintenance (no gasoline, no engine oil, no air filter, no spark plugs, no fuel storage, etc.). Rechargeable lawnmowers use an electric motor instead of a combustion engine for the drive wheels, resulting in a less complex overall structure and more flexible handling. Their application has become increasingly widespread in recent years. Rechargeable lawnmowers use a battery pack for power and a charging port to charge external electronic devices such as mobile phones, camping lights, fans, and radios.

[0003] Currently, electronic devices on the market offer a wide variety of interface types. However, due to space and circuit design limitations, rechargeable lawnmowers typically only have one adapter or one USB port. If users need to use other types of interfaces, they must use adapters. The charging efficiency of these adapters is often low, requiring a long charging time. Furthermore, these adapters are usually designed for quick plugging and unplugging, making them prone to disconnection due to contact or severe vibrations during driving, causing inconvenience to users.

[0069] The terminology used in this invention / utility model is for the purpose of describing specific embodiments only and is not intended to limit the invention. For example, terms such as "upper," "lower," "front," and "rear" indicating orientation or positional relationship are based solely on the orientation or positional relationship shown in the accompanying drawings and are used only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device / component referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention.

[0070] Compared to traditional fuel-powered lawnmowers, rechargeable lawnmowers offer advantages such as all-weather zero emissions, zero fuel consumption, low noise, and simple maintenance (no gasoline, no engine oil, no air filter, no spark plugs, no fuel storage, etc.). Rechargeable lawnmowers use electric motors instead of internal combustion engines for the drive wheels, allowing for independent control of each motor and enabling movement such as straight-ahead, reverse, turning, and zero-steering. This reduces the overall structural complexity of the vehicle, making it more flexible to control, and its application has become increasingly widespread in recent years. Rechargeable lawnmowers use battery packs for power and charging interfaces to charge external electronic devices such as mobile phones, camping lights, fans, and radios.

[0071] Currently, electronic devices on the market offer a variety of interface types, but rechargeable lawnmowers, due to space and circuit design limitations, typically only have one USB port. If users need to charge their devices using other types of interfaces, they must use adapters to connect to the USB port. These adapters are usually designed for quick plug-and-play connection to the vehicle's interface, and in some cases, multiple adapters are required before charging the user's device. In practical applications, this can easily lead to poor contact or disconnection due to accidental contact or severe vibrations from vehicle movement. This method can negatively impact user experience and also poses certain safety hazards. Furthermore, the charging efficiency of the provided ports or adapters is often low, resulting in a long charging time for electronic devices.

[0072] To address the aforementioned issues, the purpose of this specification is to provide a multi-functional vehicle, a gardening vehicle, and a ride-on lawnmower, which includes a discharge unit electrically connected to the power system. This discharge unit incorporates a fast-charging module, thereby converting and adjusting the power from the power system into fast-charging voltage and current output. This effectively meets the high-efficiency charging needs of electronic devices, eliminates safety hazards, and optimizes the user experience.

[0073] For the purposes described above, one aspect of this specification provides a multi-functional vehicle.

[0074] Referring to Figures 1 and 2, the multi-functional vehicle includes: a frame 100, a working system 102 connected to the frame 100, and a power supply system 104 for supplying power to the working system 102.

[0075] The frame 100 extends at least partially in a direction parallel to the front-rear direction, and a support assembly 1000 may be provided on the frame 100. The support assembly 1000 may include at least one of a seat or a standing platform; Figure 1 only shows an example of the support assembly 1000 including a seat. The seat or the standing platform is used for work involving sitting or standing. That is, the multi-functional vehicle can provide a riding-style working mode or a standing-style working mode. Furthermore, the structure of the seat and the standing platform can be flexibly switched, that is, the working mode of the multi-functional vehicle can be flexibly switched between a riding-style working mode and a standing-style working mode according to the actual needs of the user. A handheld operating component may also be provided on the frame 100, and based on the handheld operating component, the multi-functional vehicle can also provide a push-style working mode.

[0076] Referring to Figure 2, the working system 102 includes a power output component 1020 and a walking drive component 1022. The power output component 1020 includes an output element for outputting power to achieve a specific function. In some optional embodiments, the power output component 1020 is a lawn mowing element for achieving the lawn mowing function. The power output component 1020 is also connected to the frame 100. The power output component 1020 also includes a first drive motor for driving the lawn mowing element to rotate at high speed, and a control module corresponding to the first drive motor.

[0077] The power output component 1020 may include one or more mowing elements. 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 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.

[0078] In some alternative embodiments, the power output assembly 1020 is a cleaning element for providing power to clean the device. The power output assembly 1020 also includes a first drive motor for driving the cleaning element, and a control module corresponding to the first drive motor.

[0079] It is understood that in some alternative embodiments, the power output component 1020 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 various functional components without creative effort, and all of the above should be included in the protection scope of this embodiment.

[0080] The driving assembly 1022 is used to enable the multi-functional vehicle to travel within a landscape setting such as a lawn, garden, or fence. The driving assembly 1022 includes at least driving wheel elements and second drive motors for driving the driving wheel elements. Multiple driving wheel elements may be provided, and the number of second drive motors corresponds to the number of driving wheel elements. In some optional embodiments, the driving assembly 1022 includes a first driving wheel and a second driving wheel, and two corresponding second drive motors. The first driving wheel and the second driving wheel may also be referred to as the left driving wheel and the right driving wheel, and the two corresponding second drive motors may also be referred to as the left drive motor and the right drive motor.

[0081] When the two second drive motors drive the corresponding wheels to rotate at different power levels, a speed difference is generated between the first and second wheels, thereby enabling the multi-functional vehicle to steer. In some embodiments, the driving assembly 1022 further includes a driving controller for controlling the second drive motors.

[0082] The multi-functional vehicle also includes a power supply circuit system, which is disposed between the power supply system 104 and the operating system 102. The operating system 102 serves as a load in the multi-functional vehicle, and the power supply system 104 outputs power to the operating system 102, which serves as a load, through the power supply circuit system to drive the operating system 102 to operate.

[0083] Specifically, the power system 104 includes at least provisions for supplying power to the first drive motor in the power output assembly 1020 and the second drive motor in the travel drive assembly 1022. The power system 104 can also supply power to other electronic components in the multi-functional vehicle, such as the control module in the power output assembly 1020 corresponding to the first drive motor, and the driving controller in the travel drive assembly 1022 corresponding to the second drive motor.

[0084] As shown in Figures 1 and 2, in some optional embodiments, the working system 102 may further include a control component 1024. The control component 1024 is coupled to the walking drive component 1022 and configured to control the operating state of the walking drive component 1022 to adjust the driving state of the multi-functional vehicle. The control component 1024 includes a left control lever 1024a, a right control lever 1024b, and a corresponding rotation detection component. The rotation detection component is configured to detect the rotation direction and rotation angle of the left control lever 1024a and / or the right control lever 1024b under user control. The rotation direction can be forward rotation, backward rotation, or maintaining a neutral position, and the rotation angle is generally set to the range of [0°, 20°].

[0085] The driving controllers corresponding to the left and right drive motors can control the rotation direction and speed of the output shafts of the left and right drive motors according to the rotation direction and rotation angle of the left control lever 1024a and the right control lever 1024b, thereby driving the left and right driving wheels to rotate forward or to the right at a certain speed.

[0086] Referring to Figure 2, the power system 104 is mounted on the vehicle frame 100 and detachably connected to it. The power system 104 includes a battery compartment 1040, in which multiple battery cells 1041 can be detachably installed. The battery cells 1041 can be easily removed and installed without tools. Those skilled in the art will understand that the multiple battery cells 1041 can also be fixedly packaged within the power system 104.

[0087] The plurality of battery cells 1041 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.

[0088] 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.

[0089] 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.

[0090] 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.

[0091] 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 units 1041 in the power system 104 can also be nickel-cadmium battery cells, lead-acid battery cells, graphene cells, etc.

[0092] The power system 104 uses at least one of the first-specification battery pack and the second-specification battery pack in its multiple battery units 104. This allows the multi-functional vehicle to be compatible with different specifications of battery packs, meeting the needs of high-power operation while also being compatible with handheld electric garden tools, making the work of garden workers more flexible.

[0093] As shown in Figure 3, the multi-functional vehicle further includes a discharge unit 106, which includes multiple charging ports 200. The discharge unit 106 is electrically connected to the power system 104 and uses the multiple charging ports 200 to charge electronic devices. In the discharge unit 106, the multiple charging ports 200 are directly or indirectly electrically connected to the power system 104. The multiple charging ports 200 include at least two of the following: Micro USB, USB Type-C, and Lightning. The electronic devices may be, for example, mobile phones, tablets, laptops, radios, public address systems, camping lights, electric fans, hair dryers, etc., of different brands and models.

[0094] In some optional embodiments, the discharge unit 106 of the multi-functional vehicle may include two charging ports 200, which may be a USB Type-C interface and a Lightning interface, respectively. In other optional embodiments, the discharge unit 106 may also include three charging ports 200, which may be a Micro USB interface, a USB Type-C interface, and a Lightning interface, respectively. Those skilled in the art will understand that the discharge unit 106 may also have more charging ports 200, such as four, six, or ten, etc., and these multiple charging ports 200 may include at least two of the following: Micro USB interface, USB Type-C interface, and Lightning interface. The specific number of each type of interface can be flexibly set according to specific circumstances.

[0095] In the multi-functional vehicle, the discharge unit is electrically connected to the power system, and the discharge unit is equipped with multiple different types of charging interfaces, which can be compatible with and adapt to a variety of electronic devices. This allows for more flexible and effective fulfillment of users' charging needs for electronic devices, while also eliminating safety hazards and optimizing the user experience.

[0096] The charging interface 200 can be a charging plug or a corresponding type of charging cable connector. In some optional embodiments, the discharging unit 106 can be equipped with multiple charging cable connectors of various types to charge the user's electronic devices. This eliminates the need for the user to carry an additional charging cable, further optimizing the user experience.

[0097] To make it easier for users to charge electronic devices using the charging interfaces, the deployment positions of the multiple charging interfaces 200 on the multi-functional vehicle can be flexibly set.

[0098] As shown in Figures 4 and 5-a, 5-b, a multi-functional vehicle provided in one or more optional embodiments of this specification further includes a cover assembly 304. The cover assembly 304 is disposed on the frame 100, covering the left and / or right sides of the multi-functional vehicle to protect and decorate the vehicle body. A plurality of charging ports 200 may be disposed on the cover assembly 304.

[0099] Referring to Figures 5-a and 5-b, the covering assembly 304 includes a left cover 304a and a right cover 304b. The plurality of charging ports 200 can be flexibly disposed on the left cover 304a and the right cover 304b.

[0100] Furthermore, in some alternative embodiments, a storage compartment 3041 is recessed on the left cover 304a and / or the right cover 304b, and one or more of the charging ports 200 may be disposed on the bottom or inner wall of the storage compartment 3041.

[0101] In some alternative embodiments of a multi-functional vehicle, a display device 305 is provided at the front end of the left cover 304a and / or the right cover 304b. Figure 5-b shows the case where the display device 305 is provided at the front end of the right cover 304b. Those skilled in the art will understand that the display device 305 can also be provided on the left cover 304a. The display device 305 includes a display screen 3051 and a human-machine interface platform 3052 for receiving user control commands. The display screen 3051 faces the user's head for easy viewing, and the human-machine interface platform 3052 is equipped with one or more control buttons for user operation. Similarly, one or more charging ports 200 can also be provided on the human-machine interface platform 3052.

[0102] As shown in Figure 6, in a multi-functional vehicle provided by one or more optional embodiments of this specification, the gripping portions at the ends of the left control lever 1024a and / or the right control lever 1024b in the control assembly 1024 form a multi-functional handle 306. The multi-functional handle 306 is provided with one or more function buttons for the user to flexibly control various functional operating states of the multi-functional vehicle. Similarly, one or more charging ports 200 may be provided on the multi-functional handle 306.

[0103] In a multi-functional vehicle provided by one or more optional embodiments of this specification, a seat is selected as the load-bearing component 1000. One or more charging ports 200 may also be provided on the left and right armrests of the seat. Figure 7 shows a schematic diagram of the right armrest structure, in which the charging port 200 is located on the inner side of the right armrest near the user.

[0104] To improve space utilization in the multi-functional vehicle, multiple charging interfaces 200 can be integrated when they are deployed. As shown in FIG8, in some optional embodiments, a fusion hole 307 can be provided in the multi-functional vehicle, and multiple terminals 3071 can be integrated in the fusion hole 307, which can be used as the charging interface 200. Similar to the aforementioned embodiments, the fusion hole 307 can be flexibly set in a suitable location in the multi-functional vehicle, such as in the cover assembly 304, the multi-functional handle 306, the seat armrest, etc. FIG8 shows the case where the fusion hole 307 is set on the right cover 304b. Those skilled in the art will understand that FIG8 only shows the case where the fusion hole 307 includes two terminals 3071, and in fact, three or more terminals 3071 used as the charging interface 200 can also be integrated in the fusion hole 307.

[0105] It should be further explained that the multiple terminals 3071 integrated in the fusion hole 307 serve as the charging interface 200. These terminals 3071 can be of the same type or different types of interfaces. Referring to Figure 8, in some optional embodiments, two terminals 3071 in the fusion hole 307 can be, for example, a Micro USB interface and a USB Type-C interface, respectively. In this way, the fusion hole 307 integrates and is compatible with multiple charging interfaces, exhibiting high integration and effectively improving space utilization. It also makes actual charging operations more convenient, thereby optimizing the user experience.

[0106] As shown in Figure 3, in a multi-functional vehicle provided by one or more optional embodiments of this specification, the discharge unit 106 includes a discharge circuit 1060. The discharge circuit 1060 is electrically connected to the power system 104 and the plurality of charging interfaces 200, respectively. The power in one or more battery cells 1041 in the power system 104 can be transmitted through the discharge circuit 1060 and charged to the corresponding electronic devices of the charging interfaces 200 via the plurality of charging interfaces 200.

[0107] Referring to Figure 9, in a multi-functional vehicle provided by one or more optional embodiments of this specification, the discharge circuit 1060 may include multiple discharge branches 1061 arranged in parallel. The input terminals of the multiple discharge branches 1061 are connected to the power system 104, and the output terminals are respectively connected to multiple charging interfaces 200. The multiple charging interfaces 200 include at least two of Micro USB interfaces, USB Type C interfaces, and Lightning interfaces. Figure 9 exemplarily shows three charging interfaces 200, which are respectively selected from Micro USB interfaces, USB Type C interfaces, and Lightning interfaces.

[0108] In each of the multiple discharge branches 1061, a DC / DC conversion module 1062 is provided. The DC / DC conversion module 1062 is configured to convert the high voltage from the power supply system 104 into a stable low voltage. The high voltage of the power supply system 104 may be, for example, 20V, 48V, 50V, 58V, 60V, 72V, etc. After conversion by the DC / DC conversion module 1062, a stable low voltage can be output, for example, converted to a lower voltage level of 5V, 10V, or 15V. The low voltage output by the DC / DC conversion module 1062 in each discharge branch 1061 is matched to the electronic device corresponding to that discharge branch. Referring to Figure 9, the charging voltages required by the electronic devices corresponding to the three discharge branches 1061 shown from top to bottom are 5V, 10V, and 10V, respectively. Therefore, the three DC / DC conversion modules 1062 installed in the three discharge branches 1061 output voltages of 5V, 10V, and 10V, matching the corresponding electronic devices. With this configuration, the discharge circuit 1060 can provide different charging voltages to multiple charging interfaces 200 to meet the charging needs of different electronic devices, resulting in greater charging flexibility.

[0109] As shown in Figure 9, in a multi-functional vehicle provided by one or more optional embodiments of this specification, the discharge unit 106 further includes at least one fast charging module 202, which is directly or indirectly electrically connected to the power system 104. At least one of the fast charging modules 202 is disposed in the discharge circuit 1060 of the discharge unit 106, and charges the corresponding electronic device through at least one of the plurality of charging interfaces 200.

[0110] Specifically, the fast charging module 202 is disposed in the discharge branch 1061. In the discharge branch 1061, the DC / DC conversion module 1062 is connected in series with the fast charging module 202. The DC / DC conversion module 1062 is configured to convert the high voltage from the power system 104 into a stable low voltage. The fast charging module 202 then controls the conversion of this low voltage to output a fast charging voltage and a fast charging current to the corresponding charging interface 200. The fast charging voltage and fast charging current output by the fast charging module 202 are adapted to the electronic device connected to the charging interface 200. For example, if the electronic device requires 10V and 5A for fast charging, the fast charging module 202 in the corresponding charging branch 1061 can convert and regulate the low voltage output by the DC / DC conversion module, and output a 10V fast charging voltage and a 5A fast charging current to fast charge the electronic device.

[0111] Referring to Figure 10, in a multi-functional vehicle provided by one or more optional embodiments of this specification, the discharge circuit 1060 includes a DC / DC conversion module 1062 and a branch module 1063 connected in series.

[0112] The DC / DC conversion module 1062 is configured to convert the high voltage from the power system 104 into a stable low voltage.

[0113] The branch module 1063 includes multiple discharge branches 1061 arranged in parallel. The input terminals of the multiple discharge branches 1061 are electrically connected to the DC / DC conversion module 1062, and the output terminals of the multiple discharge branches 1061 are respectively connected to multiple charging interfaces 200. The multiple charging interfaces 200 include at least two of Micro USB interfaces, USB Type C interfaces, and Lightning interfaces. Figure 9 exemplarily shows three charging interfaces 200, which are respectively selected from Micro USB interfaces, USB Type C interfaces, and Lightning interfaces.

[0114] Considering that different electronic devices may have different charging voltage requirements, in some alternative embodiments a voltage regulating chip may be provided in at least one of the multiple discharge branches 1061 to adjust the low voltage output by the DC / DC conversion chip 1062 again.

[0115] As shown in Figure 10, in a multi-functional vehicle provided by one or more optional embodiments of this specification, the discharge unit 106 further includes at least one fast charging module 202, which is directly or indirectly electrically connected to the power system 104. At least one of the fast charging modules 202 is disposed in the discharge circuit 1060 of the discharge unit 106, and charges the corresponding electronic device through at least one of the plurality of charging interfaces 200.

[0116] Specifically, the fast charging module 202 is disposed in the discharge branch 1061 to receive the low voltage output by the DC / DC conversion module. In the discharge branch 1061, the fast charging module 202 performs conversion control on the low voltage to output a fast charging voltage and a fast charging current to the corresponding charging interface 200. The fast charging voltage and fast charging current output by the fast charging module 202 are adapted to the electronic device connected to the charging interface 200.

[0117] As shown in Figure 11, in a multi-functional vehicle provided by one or more optional embodiments of this specification, the discharge circuit 1060 includes a plurality of DC / DC conversion modules 1062 connected in series, and the low-voltage output side of each DC / DC conversion module 1062 is electrically connected to at least one of the charging interfaces 200.

[0118] The DC / DC conversion module 1062 functions to convert voltage. Multiple DC / DC conversion modules 1062 connected in series in the discharge circuit 1060 can perform multi-stage conversion on the high voltage output from the power supply system 104. Each DC / DC conversion module 1062 can output multiple successively decreasing low voltages. For example, the high voltage of the power supply system 104 can be 20V, 48V, 50V, 58V, 60V, 72V, etc. After conversion by the multiple DC / DC conversion modules 1062 connected in series, the low voltages output by the multiple DC / DC conversion modules are successively 20V, 15V, 10V, 5V, etc.

[0119] The low-voltage output side of each of the DC / DC conversion modules 1062 can be connected to at least one of the charging interfaces 200 via a discharge branch 1061. This connection method allows multiple DC / DC conversion modules 1062 to output different charging voltages through their respective charging interfaces 200, meeting the charging needs of different electronic devices and providing greater charging flexibility.

[0120] As shown in Figure 11, in a multi-functional vehicle provided by one or more optional embodiments of this specification, the discharge unit 106 further includes at least one fast charging module 202, which is directly or indirectly electrically connected to the power system 104. At least one of the fast charging modules 202 is disposed in the discharge circuit 1060 of the discharge unit 106, and charges the corresponding electronic device through at least one of the plurality of charging interfaces 200.

[0121] Specifically, the fast charging module 202 can be installed in the discharge branch 1061 connected to the low-voltage output side of multiple DC / DC conversion modules 1062. The fast charging module 202 can control the conversion of the low voltage output by the corresponding DC / DC conversion module 1062 and output a fast charging voltage and current to the corresponding charging interface 200. The fast charging voltage and current output by the fast charging module 202 are adapted to the electronic device connected to the charging interface 200. For example, if the electronic device requires 10V and 5A for fast charging, the fast charging module 202 in the corresponding charging branch 1061 can control the low voltage output by the DC / DC conversion module and output a 10V fast charging voltage and a 5A fast charging current to fast charge the electronic device.

[0122] As shown in Figure 12-a, in one or more optional embodiments of this specification, the discharge unit 106 includes at least one compatible branch 10610, and the plurality of charging interfaces 200 in the discharge unit 106 include the USB Type C interface and the Lightning interface.

[0123] The compatibility branch 10610 includes a DC / DC conversion module 1062 configured to convert a high voltage from the power system 104 into a stable low voltage. In the compatibility branch 10610, the DC / DC conversion module 1062, the USB Type-C interface, and the Lightning interface are connected in series, and the USB Type-C interface and the Lightning interface are connected via an interface conversion line 10611.

[0124] The compatible branch 10610 then uses the USB Type-C interface or the Lightning interface to charge the corresponding electronic device.

[0125] In response to the electronic device being compatible with the USB Type-C interface, the electronic device can be directly connected to the USB Type-C interface. In this case, the high voltage from the power system 104 is converted to a low voltage by the DC / DC conversion module in the compatibility branch 10610, and then used to charge the electronic device via the USB Type-C interface.

[0126] In response to the electronic device being compatible with the Lightning interface, the electronic device can be connected to the Lightning interface. In this case, the high voltage from the power system 104 is converted to a low voltage by the DC / DC conversion module in the compatibility branch 10610 and transmitted to the USB Type-C interface. It is then converted to be compatible with the Lightning interface by the interface conversion line 10611, thereby enabling the electronic device to be charged smoothly.

[0127] In the discharge unit 106, the compatible branch 10610 uses the interface conversion line 10611 to connect the USB Type C interface and the Lightning interface in series. This connection method has a high degree of circuit integration. Only one branch is needed to meet the charging needs of different types of charging interfaces. While meeting the user's flexible charging needs, it can also effectively reduce the application cost of the solution.

[0128] As shown in Figure 12-b, in a multi-functional vehicle provided by one or more optional embodiments of this specification, the discharge unit 106 further includes at least one fast charging module 202, which is directly or indirectly electrically connected to the power system 104. At least one fast charging module 202 is disposed in the discharge circuit 1060 of the discharge unit 106, and charges the corresponding electronic device through at least one of the plurality of charging interfaces 200.

[0129] Specifically, the fast charging module 202 can be located in the compatibility branch 10610. In the compatibility branch 10610, the DC / DC conversion module 1062, the fast charging module 202, the USB Type C interface, and the Lightning interface are connected in series, and the USB Type C interface and the Lightning interface are connected through an interface conversion line 10611.

[0130] In the compatible branch 10610, the fast charging module 202 can perform conversion control on the low voltage output by the corresponding DC / DC conversion module 1062, and output fast charging voltage and fast charging current to the corresponding charging interface 200, namely the USB Type C interface and the Lightning interface, so that the electronic device can be fast charged using the USB Type C interface and the Lightning interface.

[0131] In response to the electronic device being compatible with the USB Type-C interface, the electronic device can be directly connected to the USB Type-C interface. In this case, the high voltage from the power system 104 is converted to a low voltage by the DC / DC conversion module in the compatibility branch 10610, and the fast charging module 202 converts the low voltage into a fast charging voltage and fast charging current compatible with the electronic device, and then fast charges the electronic device via the USB Type-C interface.

[0132] In response to the electronic device being compatible with the Lightning interface, the electronic device can be connected to the Lightning interface. In this case, the fast charging voltage and fast charging current output by the fast charging module 202 are transmitted to the USB Type-C interface and converted by the interface conversion line 10611 to be compatible with the Lightning interface, thereby enabling the electronic device to be fast charged smoothly.

[0133] In the discharge unit 106, the compatibility branch 10610 is configured with the fast charging module 202 and uses the interface conversion line 10611 to connect the USB Type C interface and the Lightning interface in series. This connection method has a high degree of circuit integration. Only one branch is needed to meet the fast charging requirements of different types of charging interfaces. While meeting the user's flexible charging needs, it can also effectively reduce the application cost of the solution.

[0134] As shown in Figure 3, in a multi-functional vehicle provided by one or more optional embodiments of this specification, the discharge unit 106 further includes a switch control component 1064. The switch control component 1064 is configured to adjust and control the circuit connection state of the discharge circuit 1060 in the discharge unit 106, thereby controlling the charging state corresponding to the plurality of charging ports 200. For example, the switch control component 1064 can control the power transmission state of the plurality of discharge branches 1061 in the discharge circuit 1060, selectively controlling power supply to some of the charging ports 200 while de-energizing others, or selectively switching the charging mode of one or more charging ports 200, controlling fast charging of the corresponding electronic devices of the charging port 200, or exiting the fast charging mode and switching to a normal charging mode.

[0135] The switch control component 1064 can be a physical mechanical switch or an electronic switch, such as an insulated-gate bipolar transistor (IGBT), a triode, or a relay.

[0136] Referring to Figure 3, in some optional embodiments, the multi-functional vehicle includes a Vehicle Control Unit (VCU) 108. The VCU 108 is configured to monitor and control the overall operating status of the multi-functional vehicle.

[0137] In the multi-functional vehicle, the overall operating status of the discharge unit 106 can also be managed by the vehicle controller 108. Specifically, the switch control component 1064 is configured to communicate with the vehicle controller 108 and control the charging status of the multiple charging interfaces 200 based on control commands from the vehicle controller 108.

[0138] Referring to Figure 3, in some alternative embodiments, the power system 104 in the multi-functional vehicle includes a power management system (BMS) 1042, which is configured to monitor and manage the operating status of at least a plurality of battery cells 1041 in the power system 104.

[0139] In the multi-functional vehicle, the power management controller 1042 can also be used to manage the overall operating status of the discharge unit 106. Specifically, the switch control component 1064 is configured to communicate with the power management controller 1042 in the power system 104, and controls the charging status of the multiple charging interfaces 200 based on control commands from the power management controller 1042.

[0140] As shown in Figure 13, in a multi-functional vehicle provided by one or more optional embodiments of this specification, the discharge unit 106 further includes the switch control component 1064 and the charging controller 1065. The charging controller 1065 is communicatively connected to the switch control component 1064 and configured to control the charging states of the multiple charging ports 200 using the switch control component 1064. The charging controller 1065 can directly or indirectly receive control commands from a user, and control the switch control component 1064 based on the control commands, thereby adjusting the charging operation states of the multiple charging ports 200.

[0141] As shown in Figure 14, in a multi-functional vehicle provided by one or more optional embodiments of this specification, the fast charging module 202 includes a boost / boost assembly 2021 and a fast charging control assembly 2022.

[0142] The step-up / step-down assembly 2021 is configured to be electrically connected to the DC / DC conversion module 1062 to receive the low voltage output by the DC / DC conversion module 1062.

[0143] The fast charging control component 2022 is configured to communicate with the electronic device through the charging interface 200 to determine the target charging voltage and target charging current required by the electronic device.

[0144] The fast charging control component 2022 is further configured to control the buck-boost component 2021 based on the target charging voltage and the target charging current, so that the buck-boost component outputs the fast charging voltage and the fast charging current to the corresponding electronic device. The fast charging voltage and the fast charging current are respectively matched with the target charging voltage and the target charging current.

[0145] For example, the fast charging control component 2022 communicates with the electronic device through the charging interface 200 to obtain the target charging voltage and target charging current required by the electronic device for fast charging, which are 10V and 5A respectively. Further, the fast charging control component 2022 can control the buck-boost component 2021 based on the determined target charging voltage and target charging current, so that the buck-boost component 2021 outputs a 10V fast charging voltage and a 5A fast charging current to fast charge the electronic device.

[0146] In some optional embodiments, the fast charging control component 2022 is configured to communicate with the electronic device via the charging interface 200, thereby receiving fast charging request information from the electronic device through the charging interface 200. The fast charging control component 2022 can determine the corresponding target charging voltage and target charging current of the electronic device based on the fast charging request information.

[0147] The fast charging request information sent by the electronic device to the fast charging control component 2022 through the charging interface 200 can be dynamically updated according to the operating status of the electronic device's own charging process, that is, the target charging voltage and the target charging current can be modified and adjusted in real time.

[0148] The fast charging control component 2022 is also configured to respond to the real-time dynamically updated fast charging request information, and control the buck-boost component 2021 to dynamically adjust the output fast charging voltage and fast charging current in real time for the target charging voltage and target charging current that are modified and adjusted in real time, so as to ensure that the fast charging module 202 can perform stable and continuous fast charging for the electronic device, guarantee charging efficiency, and effectively optimize the user experience.

[0149] As shown in Figure 15, in a multi-functional vehicle provided by one or more optional embodiments of this specification, the fast charging module 202 may be an integrated control chip 2023. The integrated control chip 2023 is disposed in the discharge circuit 1060 of the discharge unit 106, and the DC / DC conversion module 1062 is connected in series with the integrated control chip 2023 in the discharge circuit 1060.

[0150] The DC / DC conversion module 1062 is configured to convert a high voltage from the power supply system into a stable low voltage.

[0151] The input port 2023a of the integrated control chip 2023 is electrically connected to the DC / DC conversion module 1062 and is configured to receive the low voltage output by the DC / DC conversion module 1062.

[0152] The communication port 2023b of the integrated control chip 2023 is connected to the electronic device through the charging interface 200 to determine the target charging voltage and target charging current required by the electronic device.

[0153] The integrated control chip 2023 is further configured to adjust the low voltage received by the input port 2023a into a fast charging voltage and a fast charging current based on the target charging current, and to output the fast charging voltage and the fast charging current to the electronic device via the charging interface 200 using the output port 2023c of the integrated control chip 2023.

[0154] The fast charging voltage and the fast charging current are respectively matched with the target charging voltage and the target charging current.

[0155] Referring to Figure 16, a portion of the discharge circuit in the discharge unit 106 is shown, with only a single charging interface (taking a USB Type-C interface as an example) shown; the rest is not shown. This partial discharge circuit is configured with multiple DC / DC conversion modules 1062 (DC / DC-1; DC / DC-2) connected in parallel.

[0156] The power system 104 outputs a stable low voltage Vcc1 through the DC / DC-1 conversion module. This low voltage Vcc1 is output to the USB Type C interface through the switching transistor Q1. When the switching transistor Q1 is closed and conducting, the corresponding electronic device can be slowly charged through the USB Type C interface.

[0157] The power system 104 outputs a stable low voltage Vcc2 through a DC / DC-2 conversion module. This low voltage Vcc2 is connected to the input port 2023a of the integrated control chip 2023. The communication port 2023b and output port 2023c of the integrated control chip 2023 are connected to the USB Type-C interface. A switching transistor Q2 is connected in series between the output port 2023c and the USB Type-C interface.

[0158] The integrated control chip 2023 communicates with the corresponding electronic device through the communication port 2023b and the USB Type C interface. After the communication connection is successful, the integrated control chip 2023 obtains the target charging voltage and target charging current required by the electronic device.

[0159] After confirming a successful communication connection, the integrated control chip 2023 can also control the switching transistor Q1 to open and the switching transistor Q2 to close and conduct, thereby switching the slow charging power transmission for the electronic device. Instead, the output port 2023c of the integrated control chip 2023 outputs a converted and adjusted fast charging voltage and fast charging current to fast charge the electronic device. The fast charging voltage and fast charging current are determined based on the target charging voltage and the target charging current, and are matched to these values.

[0160] In a multi-functional vehicle provided in one or more optional embodiments of this specification, the fast charging module 202 is further configured to switch the charging mode of the electronic device, and can flexibly switch between fast charging mode and non-fast charging mode according to actual conditions.

[0161] In fast charging mode, the fast charging module 202 outputs the fast charging voltage and the fast charging current to charge the electronic device.

[0162] In response to the electronic device not meeting the fast charging conditions, the fast charging module 202 controls the exit from the fast charging mode.

[0163] In some optional embodiments, after the fast charging module 202 establishes a communication connection with the electronic device corresponding to the charging interface 200, it also collects the temperature of the electronic device in real time and switches the charging mode according to the temperature change of the electronic device.

[0164] Those skilled in the art will understand that when the fast charging module 202 fast charges the electronic device, the charging power is high, and the electronic device, especially its battery, will heat up rapidly. The lifespan of the electronic device is affected by high temperatures; prolonged exposure to excessively high temperatures will significantly shorten its lifespan. Therefore, the fast charging module 202 can adjust and switch the charging mode of the electronic device in a timely manner based on its temperature changes. Specifically, the fast charging module 202 can periodically compare the temperature of the electronic device with a preset charging temperature threshold. The time period for temperature comparison can be flexibly set and adjusted according to actual conditions; for example, the temperature comparison time period can be set to 1 second, 2 seconds, 3 seconds, 5 seconds, etc.

[0165] If the temperature of the electronic device is greater than or equal to the preset charging temperature threshold, it indicates that the current temperature of the electronic device is too high, which may affect its service life, and the electronic device is determined not to meet the fast charging conditions.

[0166] In this situation, the fast charging module 202 can be controlled to exit the fast charging mode, and the discharge unit 106 charges the electronic device in a normal slow charging mode. Compared to the fast charging mode, the charging power is significantly reduced in the full charging mode, so the temperature of the electronic device can gradually decrease to a safe temperature range. This control method can effectively prevent the temperature from becoming too high due to high-power fast charging, thereby greatly reducing the impact on the service life of the electronic device.

[0167] It should be noted that in practical applications, users often want to complete the charging process of the electronic device in the shortest possible time. However, continuously using fast charging mode may affect the lifespan of the electronic device; therefore, it is necessary to avoid keeping the electronic device in fast charging mode continuously. In some optional embodiments, after controlling the exit from fast charging mode, the fast charging module 202 is further configured to periodically compare the temperature of the electronic device with a preset lower temperature threshold, where the lower temperature threshold is lower than the charging temperature threshold.

[0168] If the temperature of the electronic device is below a preset lower temperature threshold, it indicates that the temperature of the electronic device is at a low level. In this case, fast charging the electronic device will require a longer time for its temperature to rise to the charging temperature threshold. During this extended period, high-power fast charging can be performed without affecting the lifespan of the electronic device. Therefore, after determining that the temperature of the electronic device is below the preset lower temperature threshold, the fast charging module 202 can switch to fast charging mode to efficiently fast charge the electronic device with higher charging power. This method ensures that the lifespan of the electronic device is not affected while maximizing the charging efficiency.

[0169] For the same purpose, in another aspect, embodiments of this specification also provide a gardening vehicle.

[0170] Referring to Figures 1 and 2, the gardening vehicle includes: a frame 100, a working system 102 connected to the frame 100, and a power supply system 104 for supplying power to the working system 102.

[0171] The frame 100 extends at least partially in a direction parallel to the front-rear direction, and a support assembly 1000 may be provided on the frame 100. The support assembly 1000 may include at least one of a seat or a standing platform; Figure 1 only shows an example of the support assembly 1000 including a seat. The seat or the standing platform is used for sitting or standing while working. That is, the gardening vehicle can provide a riding-style working mode or a standing-style working mode. Furthermore, the structure of the seat and the standing platform can be flexibly switched, that is, the working mode of the gardening vehicle can be flexibly switched between a riding-style working mode and a standing-style working mode according to the actual needs of the user. A handheld operating component may also be provided on the frame 100, and based on the handheld operating component, the gardening vehicle can also provide a push-style working mode.

[0172] Referring to Figure 2, the working system 102 includes a power output component 1020 and a walking drive component 1022.

[0173] The power output component 1020 may include one or more mowing elements. 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 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.

[0174] In some alternative embodiments, the power output assembly 1020 is a cleaning element for providing power to clean the device. The power output assembly 1020 also includes a first drive motor for driving the cleaning element, and a control module corresponding to the first drive motor.

[0175] It is understood that in some alternative embodiments, the power output component 1020 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 various functional components without creative effort, and all of the above should be included in the protection scope of this embodiment.

[0176] The driving assembly 1022 is used to enable the landscaping vehicle to travel within landscaping areas such as lawns, gardens, and fences. The driving assembly 1022 includes at least driving wheel elements and second drive motors for driving the driving wheel elements. Multiple driving wheel elements may be provided, and the number of second drive motors corresponds to the number of driving wheel elements. In some optional embodiments, the driving assembly 1022 includes a first driving wheel and a second driving wheel, and two corresponding second drive motors. The first driving wheel and the second driving wheel may also be referred to as the left driving wheel and the right driving wheel, and the two corresponding second drive motors may also be referred to as the left drive motor and the right drive motor.

[0177] When the two second drive motors drive the corresponding walking wheels to rotate at different power levels, a speed difference is generated between the first and second walking wheels, thereby enabling the gardening vehicle to steer. In some embodiments, the walking drive assembly 1022 further includes a driving controller for controlling the second drive motors.

[0178] The gardening vehicle also includes a power supply circuit system, which is located between the power supply system 104 and the working system 102. The working system 102 serves as the load in the gardening vehicle, and the power supply system 104 outputs power to the working system 102, which serves as the load, through the power supply circuit system to drive the working system 102 to operate.

[0179] Specifically, the power system 104 includes at least provisions for supplying power to the first drive motor in the power output assembly 1020 and the second drive motor in the travel drive assembly 1022. The power system 104 can also supply power to other electronic components in the gardening vehicle, such as the control module in the power output assembly 1020 corresponding to the first drive motor, and the travel controller in the travel drive assembly 1022 corresponding to the second drive motor.

[0180] As shown in Figures 1 and 2, in some optional embodiments, the working system 102 may further include a control component 1024.
