[0057] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0058] At present, in existing multi-functional vehicles, control modules with different functions are generally installed at different positions of the main frame 100, which is not only cumbersome to assemble and occupy space, but also inconvenient to repair and replace. In other multi-functional vehicles, the control modules use a large number of circuit boards, which leads to a large number of wiring harnesses connecting the circuit boards, and the complexity of disassembly and maintenance is high, which increases the complexity of the whole machine assembly, and indirectly leads to an increase in production costs.

[0059] The present application provides a multifunctional vehicle, which arranges the control module in an all-in-one integrated manner, which not only reduces the space occupied by the control module, but also saves the use of wiring harnesses, has a high degree of integration, and is quick and convenient to disassemble and repair.

[0060] See also Figure 1 and Figure 2, is a multifunctional vehicle provided in one embodiment of the present application, which is widely used in fields such as daily life and industrial production. The outdoor tool equipment provided in the present application, the multifunctional vehicle is specifically a riding lawn mower, which can walk outdoors and mow grass. It can be understood that the multifunctional vehicle can also be other vehicles that walk outdoors, such as multi-purpose vehicles, and can also be beach cars, farmer's cars, golf carts, etc. The multifunctional vehicle can also be a vehicle that can realize another function in addition to the walking function like the riding lawn mower shown in this embodiment, such as a snowplow, which can walk outdoors and realize the function of sweeping snow, and can also be an agricultural machinery vehicle, such as a harvester, a sprayer, etc.

[0061] The main frame 100 at least partially extends in parallel to the front-rear direction, and a carrying mechanism may be provided on the main frame 100. The carrying mechanism is used to carry the operator of the multi-functional vehicle, and may include at least one of a seat 600 or a standing platform. The seat 600 or the standing platform is used for sitting or standing during work. That is, the multi-functional vehicle can provide a riding working mode or a standing working mode. Furthermore, the structure of the seat 600 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 working mode and a standing working mode according to the actual needs of the working user. A handheld operating component may also be provided on the main frame 100, and based on the handheld operating component, the multi-functional vehicle may also provide a hand-push working mode.

[0062] The multifunctional vehicle comprises a main frame 100, a seat 600, a power output assembly 200, a travel assembly 300, an operating assembly 700, a power supply device 400 and a controller assembly 500. The main frame 100 extends along a first straight line direction 101 parallel to its front-rear direction on the working surface. Among them, the seat 600 is installed on the main frame 100 for users to sit on. The main frame 100 is also used to install the power output assembly 200, the travel assembly 300, the operating assembly 700 and the power supply device 400. The power supply device 400 is used to provide an energy source for the power units of the entire multifunctional vehicle, such as enabling the cutting assembly to perform cutting operations, and enabling the travel assembly 300 to support the main frame 100 and related components on the main frame 100 to travel and power consumption of other power units. The controller assembly 500 is used to control the multifunctional vehicle to perform outdoor operations.

[0063] Reference Figure 1 and Figure 2, the power output assembly 200 is used as a workpiece to realize the tool function. In this embodiment, the multifunctional vehicle is a riding lawn mower, and the power output assembly 200 is specifically a cutting assembly, which is used to output power to realize the mowing function of the riding lawn mower. The cutting assembly is set to 2 groups or 3 groups. The cutting assembly is arranged below the main frame 100. In one embodiment, the cutting assembly includes: a blade, a mowing element and a cutting motor. The mowing element is used to cut vegetation such as grass when rotating at a high speed. For example, the mowing element is a blade for cutting vegetation on a lawn. The blade is formed with a mowing space for accommodating the mowing element, and the mowing element is at least partially located in the mowing space. In some embodiments, the number of mowing elements can be 2, and correspondingly, the number of cutting motors is also 2. The two cutting motors independently drive the two mowing elements. In some embodiments, the number of mowing elements can be 3, and correspondingly, the number of cutting motors is also 3. The three cutting motors independently drive the three mowing elements.

[0064] Of course, the power output assembly 200 can also be removed from the multi-purpose vehicle. In some embodiments, it can be understood that the power output assembly 200 can be replaced with other components. Therefore, the outdoor garden mower can not only cut vegetation, but also replace the cutting assembly with functional components such as snow shoveling, snow sweeping, snow blowing, and flushing. Technical personnel in this field should be able to adaptively replace various functional components without creative work, and all of the above should be included in the protection scope of this embodiment.

[0065] The walking assembly 300 includes a walking wheel arranged on the main frame 100 and a walking motor 301 for driving the walking wheel. The walking wheels are arranged on both sides of the main frame 100 so that the center of gravity of the multifunctional vehicle is kept in the main frame 100 to reduce the probability of the multifunctional vehicle rolling over when walking. In one embodiment, the number of the walking wheels is set to 4, including 2 front walking wheels and 2 rear walking wheels respectively. The front walking wheel can be a universal wheel, and the walking motor 301 is connected to the rear walking wheel and drives the rear walking wheel to rotate. The two rear walking wheels are matched with the walking motor 301, and the rotation speeds of the two walking motors 301 can be the same or different. When the user drives the multifunctional vehicle straight, the rotation speeds of the two walking motors 301 are roughly the same; when the user drives the multifunctional vehicle to turn, the rotation speeds of the two walking motors 301 are different, and the multifunctional vehicle turns to the side with a low rotation speed of the walking motor 301. In some embodiments, the diameter of the front walking wheel is smaller than the diameter of the rear walking wheel. Of course, the number of the walking wheels can also be set to 3 or 5.

[0066] In one embodiment, the running wheels may be configured as running devices of other structures that support the running of the multi-purpose vehicle.

[0067] The operating assembly 700 includes a left operating rod 701 and a right operating rod 702 disposed on the left and right sides of the multi-functional vehicle. The user controls the multi-functional vehicle to move forward, backward or turn by manipulating the left operating rod 701 and the right operating rod 702. The operating assembly 700 can also be a steering wheel capable of controlling the multi-functional vehicle. The present application also includes a brake assembly disposed on the upper surface in front of the main frame 100 for the user to step on to control the operating state of the multi-functional vehicle.

[0068] The power supply device 400 is arranged at the rear of the multi-functional vehicle. The power supply device 400 includes a battery pack 401, a BMS control board 109 for controlling the output and input of the battery pack 401, and a battery compartment for installing the battery pack 401. The battery pack 401 is electrically connected to the electrical connection terminals on the battery compartment through the electrical connection terminals thereon to supply power to the multi-functional vehicle. Preferably, the battery compartment can be configured to accommodate battery packs 401 of different capacities to increase the compatibility of the multi-functional vehicle with different battery packs 401. Among them, the battery pack 401 can also be disassembled to power other power tools, which increases the versatility of the battery pack 401. Compared with the traditional use of fossil fuels as an energy source, the multi-functional vehicle of the present application is more environmentally friendly and more in line with long-term development plans. Preferably, the battery pack 401 preferably uses lithium iron phosphate batteries or ternary lithium batteries.

[0069] like Figure 5 In one embodiment, the controller assembly 500 is configured to control the multi-functional vehicle to perform outdoor operations, and the controller assembly 500 is configured to include at least a power output controller 517, a travel controller 518, and a VCU module 515. In one embodiment, such as in a riding lawn mower, the power output controller 517 is a cutting motor controller, which controls the output of the cutting motor, and then controls the operation of the mowing element to perform cutting at high speed, medium speed, or low speed. Of course, the power output controller 517 can also be a controller for controlling operational functional components such as snow shoveling, snow sweeping, snow blowing, and flushing. The VCU (Vehicle control unit) module 515 serves as a central control unit for controlling the operation of the entire multi-functional vehicle.

[0070] The travel controller 518 is a controller for controlling the operation of the travel wheels of the entire multi-purpose vehicle, including controlling riding lawn mowers, snowplows, snow sweepers, snow blowers, flushing equipment, etc.

[0071] like Figure 5 and Figure 6 In one embodiment, the controller assembly 500 includes a shell and an all-in-one control module disposed in the shell. The all-in-one control module includes a control board 514 and a power board 516. This arrangement allows the controller assembly 500 to occupy less space, reduces the layout of the wiring harness, and saves costs.

[0072] Specifically, the control board 514 includes a plurality of power output control modules 509 and a plurality of travel control modules 512 , and the power board 516 includes a plurality of power output power modules 510 and a plurality of travel power modules 513 .

[0073] In a preferred embodiment, one control panel 514 integrates at least one power output control module 509 and one walking control module 512. One control panel 514 may also integrate two power output control modules 509 and one walking control module 512, or two power output control modules 509 and two walking control modules 512, or more than two power output control modules 509 and more than two walking control modules 512. The specific layout can be based on demand. Preferably, one control panel 514 integrates two power output control modules 509 and two walking control modules 512.

[0074] One power board 516 integrates at least one power output power module 510 and at least one walking power module 513, or one power board 516 may also integrate two power output power modules 510 and one walking power module 513, or integrate two power output power modules 510 and two walking power modules 513, or more than two power output power modules 510 and more than two walking power modules 513, which may be specifically arranged according to needs. Preferably, one power board 516 integrates two power output power modules 510 and two walking power modules 513.

[0075] In one embodiment, the power output power module 510 and the travel power module 513 are respectively arranged in independent areas on a power board, which is conducive to the production, assembly and maintenance of the power output power module 510 and the travel power module 513 on the power board 516, and also reduces the signal interference between the power output power module 510 and the travel power module 513. Similarly, the power output control module 509 and the travel control module 512 are arranged in relatively independent areas on the control board 514, which is conducive to the production, assembly and maintenance of the power output control module 509 and the travel control module 512 on the control board 514, and also reduces the signal interference between the power output control module 509 and the travel control module 512.

[0076] It should be understood that a power module and a control module are combined into a controller for controlling the operation of the power output assembly 200 or the travel assembly 300 .

[0077] In one embodiment, the bottom wall of the shell is the heat dissipation portion 503, and the control board 514 is arranged above the power board 516 in the shell. The power output power module 510 and the travel power module 513 are attached to the bottom wall of the shell in a manner of being combined with a power board 516. The power output power module 510 and the travel power module 513 that generate higher heat are cooled through the bottom wall of the shell, thereby achieving good heat dissipation for the controller assembly 500.

[0078] In one embodiment, at least part of the housing is configured with a heat dissipation portion 503 for dissipating heat from the all-in-one control module, the heat dissipation portion 503 is extended along a working surface, and the ratio of the maximum projection area of ​​the heat dissipation portion 503 on the working surface to the cutting width of the cutting assembly is greater than or equal to 39 mm. 2 / mm and less than or equal to 115mm 2 / mm. That is, when the number of cutting motors in the cutting assembly increases, the corresponding cutting width of the mowing assembly also increases accordingly, and the required heat dissipation requirements also increase, which will further increase the size of the heat dissipation unit 503. Preferably, the ratio of the maximum projection area of ​​the heat dissipation unit 503 on the working surface to the cutting width of the cutting assembly is 39mm 2 / mm, 80mm 2 / mm or 115mm 2 / mm.

[0079] Specifically, the entire bottom wall of the housing serves as the heat dissipation portion 503 .

[0080] In one embodiment, taking a riding lawn mower as an example, when the power output assembly 200 is a cutting assembly, and the cutting assembly is two cutting motors, the ratio of the maximum projection area of ​​the heat dissipation portion 503 on the working surface to the cutting width of the cutting assembly is greater than or equal to 73 mm. 2 / mm and less than or equal to 83mm 2 / mm. Preferably, the ratio of the maximum projection area of ​​the heat dissipation portion 503 on the working surface to the cutting width of the cutting assembly is 73mm 2 / mm, 76mm 2 / mm or 83mm 2 / mm.

[0081] In another embodiment, taking a riding lawn mower as an example, when the power output assembly 200 is a cutting assembly, and the cutting assembly is composed of three cutting motors, the ratio of the maximum projection area of ​​the heat dissipation portion 503 on the working surface to the cutting width of the cutting assembly is greater than or equal to 48 mm. 2 / mm and less than or equal to 68mm 2 / mm. Preferably, the ratio of the maximum projection area of ​​the heat dissipation portion 503 on the working surface to the cutting width of the cutting assembly is 48mm 2 / mm, 60mm2 / mm or 68mm 2 / mm.

[0082] In one embodiment, the rated total power of the controller assembly 500 is greater than 3 kW, preferably, the rated total power of the controller assembly 500 is 5 kW. The instantaneous power of the controller assembly 500 is greater than 9 kW, preferably, the instantaneous power of the controller assembly 500 is 11 kW. Furthermore, the ratio of the maximum projected area of ​​the controller assembly 500 on the working surface to the rated power of the controller assembly 500 is greater than or equal to 11910 mm 2 / kw and less than or equal to 29792mm 2 / kw, that is, the larger the rated power of the controller assembly 500, the larger the area of ​​the controller heat sink 503 is set accordingly, and the increase in the area of ​​the heat sink 503 is helpful to dissipate the heat of the high-power controller assembly 500. Preferably, the ratio of the maximum projection area of ​​the controller assembly 500 on the working surface to the rated power of the controller assembly 500 is 11910mm 2 / kw、20000mm 2 / kw or 29792mm 2 / kw.

[0083] In one embodiment, the multi-functional vehicle is a riding lawn mower, and its power output assembly 200 is a cutting assembly, wherein the cutting assembly includes a plurality of cutting motors, and the travel assembly 300 includes a plurality of travel motors 301, one cutting motor matches a first inverter array 5101 on the power board 516, and one travel motor 301 matches a second inverter array 5131 on the power board 516, and one first inverter array 5101 or one second inverter array 5131 matches at least 4 power switches; of course, one inverter array on the power board 516 for one cutting motor or one travel motor 301 can also match 6 power switches, and the power board 516 is provided with a plurality of inverter arrays, and the ratio of the number of inverter arrays to the number of power boards 516 is greater than or equal to 2, preferably 2 or 3. Such a setting is to realize the control of multiple motors on one power board 516, and then realize the integrated setting of the circuit board on the controller.

[0084] In one embodiment, in order to improve the heat dissipation effect of the heat dissipation part 503, a plurality of heat dissipation ribs are arranged on the outer side of the heat dissipation part 503 located on the shell, and the extending direction of the heat dissipation ribs is consistent with the moving direction of the multi-functional vehicle. The setting of the direction of the heat dissipation ribs is conducive to accelerating the heat dissipation of the controller assembly 500 during the moving process of the multi-functional vehicle.

[0085] In one embodiment, the cross-sectional area of ​​a single heat dissipation rib is smaller than the area of ​​a single side of the single heat dissipation rib in the first straight line direction 101. That is, the outer surface area of ​​the heat dissipation rib is not arranged neatly, but protrusions or grooves are arranged on its outer surface to increase its heat dissipation effect.

[0086] In one embodiment, the opposite surface of the power board 516 on which the power switch is installed is arranged in close contact with the heat dissipation part 503, so that the heat generated by the power board 516 can be promptly and quickly transferred to the heat dissipation part 503, and the heat dissipation part 503 quickly dissipates heat through the heat dissipation ribs.

[0087] Please also see Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 In another embodiment, the controller assembly 500 is configured to include a housing and an all-in-one control module disposed in the housing, the all-in-one control module includes at least one power output controller 517 and at least one travel controller 518 integrated on a circuit board, a power output controller 517 includes a power output control module 509 and a power output power module 510, and a travel controller 518 includes a travel control module 512 and a travel power module 513. That is, all control modules and power modules related to power output control and travel control are integrated on a circuit board. Such a configuration makes the space occupied by the controller in the up and down directions of the multi-purpose vehicle smaller, can reduce the thickness of the controller assembly 500, and also reduces the layout of the wiring harness.

[0088] The above-mentioned method of integrating the power output control module 509, the power output power module 510, the walking control module 512 and the walking power module 513 can realize heat dissipation of the modules through the bottom wall of the shell, thereby improving the heat dissipation effect of the controller.

[0089] Compared with the traditional control module that uses a heat dissipation part 503 that matches its area size alone, the present application uses a large heat dissipation part 503 to dissipate heat for multiple controllers, and the heat dissipation effect is better. Specifically, when the power output controller 517 and the walking controller 518 work at the same time, the part of the heat dissipation part 503 occupied by the power output controller 517 and the part of the heat dissipation part 503 occupied by the walking controller 518 can conduct heat to each other, and the part with a higher temperature can transfer the temperature to the part with a lower temperature, so that the heat dissipation effect of the controller assembly 500 is better. When the multi-functional vehicle is only in the walking mode, the power output controller 517 does not generate heat. At this time, the heat dissipation part 503 only needs to dissipate the heat generated by the walking controller 518, and the part originally used to dissipate heat for the power output controller 517 can be used to dissipate heat for the walking controller 518, thereby greatly improving the heat dissipation effect of the walking controller 518. Similarly, when the multi-function vehicle is only in power output mode (when the multi-function vehicle is a riding lawn mower, the power output mode is the lawn mower mowing operation), the travel controller 518 does not generate heat. At this time, the heat dissipation unit 503 only needs to dissipate the heat generated by the power output controller 517. The part originally used to dissipate heat for the travel controller 518 can be used to dissipate heat for the power output controller 517, thereby greatly improving the heat dissipation effect of the power output controller 517.

[0090] like Fig. 9 As shown, in one embodiment, four areas, namely, a first control area, a first power area, a second control area, and a second power area, are set on the circuit board, and the power output control module 509, the power output power module 510, the walking control module 512, and the walking power module 513 integrated on one circuit board are respectively allocated in different areas. Specifically, the power output control module 509 is correspondingly set in the first control area, the power output power module 510 is correspondingly set in the first power area, the walking control module 512 is correspondingly set in the second control area, and the walking power module 513 is correspondingly set in the second power area. Such a layout enables modules performing the same functions to be in one area, which is convenient for production, assembly, and maintenance.

[0091] like Fig.11 and Fig.13As shown, in one embodiment, the power output controller 517 includes at least one first inverter array 5101, and the travel controller 518 includes at least one second inverter array 5131. The bottom of the housing of the controller assembly 500 is configured as a heat dissipation portion 503, and the ratio of the sum of the number of the first inverter array 5101 and the second inverter array 5131 to the number of the heat dissipation portion 503 is greater than or equal to 2. This arrangement is to enable a heat dissipation portion 503 to dissipate heat for the inverter arrays of more than two controllers integrated on a circuit board. This arrangement not only meets the purpose of heat dissipation, but also meets the integrated setting of the controller assembly 500, reducing the overall spatial layout of the controller assembly 500, so as to achieve the design concept of intensive vehicle operation.

[0092] In a specific implementation, the first inverter array 5101 and the second inverter array 5131 disposed on a circuit board are both disposed in close contact with the heat dissipation portion 503 to achieve the best heat dissipation effect.

[0093] It should be noted that the power output power module 510 includes the above-mentioned first inverter array 5101. When the power output unit is a cutting component, the power output control module 509 can be specifically a cutting controller, and the travel power module 513 includes the above-mentioned second inverter array 5131.

[0094] Please also see Figure 7 and Figure 8 As shown, in one embodiment, as Figure 1 In order to reduce the mutual interference between the power output control part and the walking control part, in another preferred embodiment, the controller assembly 500 is configured to include a housing and a first all-in-one control module 1 and a second all-in-one control module 2 arranged in the housing, the first all-in-one control module 1 includes at least one power output controller 517 integrated on a first circuit board, a power output controller 517 includes a power output control module 509 and a power output power module 510, and the second all-in-one control module 2 includes at least one walking controller 518 integrated on a second circuit board, a walking controller 518 includes a walking control module 512 and a walking power module 513. Such a configuration greatly reduces the interference between the power output controller 517 and the walking controller 518, thereby ensuring the use effect and service life of the controller assembly 500.

[0095] Specifically, the power output control module 509 and the power output power module 510 on the first circuit board are respectively arranged in different areas of the first circuit board to facilitate the production, assembly and maintenance of the first circuit board. Similarly, the travel control module 512 and the travel power module 513 on the second circuit board are also respectively arranged in different areas of the second circuit board to facilitate the production, assembly and maintenance of the second circuit board.

[0096] It should be understood that the power board 516 is the main part that generates higher heat in the controller assembly 500 of the present application, and the control board 514 also generates heat, but less.

The ratio of the number of walking motors 301 to the number of the second all-in-one control module 2 is greater than or equal to 2, and preferably, the ratio of the number of walking motors 301 to the number of the second all-in-one control module 2 is 2, 3 or 5. One control module satisfies the control of the operation of more than two motors, thereby improving the integrated layout of the controller.

Specifically, the first all-in-one control module 1 includes at least two cutting controllers integrated on the first circuit board component, and the second all-in-one controller includes at least two walking controllers 518 integrated on the second circuit board component.

When the current is too large, the first safety device 5105 and the second safety device 5135 will both fuse due to the protection of the circuit board. Among them, the first conductive member 531 and the second conductive member 529 are both copper bars.

Since the power board 516 has a large heat dissipation, such an arrangement enables the controller assembly 500 to have a better heat dissipation effect.

[0101] Please also see Fig.28 Furthermore, the housing is provided with a first bracket 533 for mounting the first control board 10 and a second bracket 534 for mounting the second control board 30.

When installed, the first control board 10 is placed in the concave part of the first bracket 533, and the second control board 30 is also placed in the concave part of the second bracket 534.

[0102] Furthermore, the first bracket 533 used by the first control panel 10 and the second bracket 534 used by the second control panel 30 may have the same size.
