Description

Technical Field

[0001] This invention relates to the field of lawnmower technology, and in particular to a lawnmower with a movable power module. Background Technology

[0002] Lawn mowers are used for trimming and maintaining lawns, and different types are selected for different terrain environments. For example, for large areas such as golf courses or football fields where trimming is more demanding, ride-on lawn mowers are often used, as they are more convenient to operate and more efficient.

[0003] Currently available ride-on lawnmowers are generally divided into gasoline-powered and electric-powered types. Electric-powered lawnmowers have several advantages over gasoline-powered lawnmowers, including being quieter, more environmentally friendly, and having a simpler structure, and are gradually replacing gasoline-powered ones. However, electric-powered lawnmowers also have the following disadvantages:

[0004] First, due to the limitation of battery power, the lawnmower has limited range and can only mow a small area at a time.

[0005] Second, operators must constantly monitor the battery level to avoid running out of power before returning to the charging point. If this happens, the operator will need to manually push the entire lawnmower back to recharge, which is laborious and time-consuming.

[0006] In view of this, it is necessary to provide an improved lawnmower to overcome the existing defects. Summary of the Invention

[0007] Therefore, it is necessary to provide a lawnmower with better battery life and more convenient charging to address the aforementioned technical issues.

[0120] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0121] It should be noted that when a component is said to be "attached" to another component, it can be directly on the other component or it can be in the middle of another component. When a component is said to be "set" to another component, it can be directly set to the other component or it may also be in the middle of another component. When a component is said to be "fixed" to another component, it can be directly fixed to the other component or it may also be in the middle of another component.

[0122] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0123] Please see Figure 1-3 This invention provides a lawnmower 100, which includes a frame 1, wheels 2 mounted under the frame 1, a cutting component 16, functional components for driving the wheels 2 and the cutting component 16, and a power source providing power to the functional components. The lawnmower 100 achieves its walking function by driving the wheels 2 through the functional components, and achieves its cutting function by driving the cutting component 16 through the functional components. This lawnmower is a wheeled mobile vehicle. This application is not limited to protecting lawnmowers, but also includes other wheeled mobile vehicles, such as scooters, electric bicycles, and other mobile vehicle structures.

[0124] like Figure 3 As shown, the frame 1 serves as the skeleton of the lawnmower 100, and its overall shape is similar to that of a tractor cab. Wheels 2, cutting components 16, functional parts, power source, and other devices are all mounted on the frame 1. During operation, the operator remains seated on the frame 1. This lawnmower 100 is a ride-on type, which, compared to traditional push-type lawnmowers, eliminates the need for the operator to walk behind the lawnmower 100 or exert force to control its movement, making it more convenient and labor-saving to use. The frame 1 needs to be made of a metal material with sufficient strength to meet its strength requirements while also controlling costs; steel is the preferred material.

[0125] Wheels 2 are mounted below the frame 1 to enable the lawnmower 100 to move. In this application, the forward and backward direction of the lawnmower 100 is defined as the direction of travel, and the left and right directions are defined as the direction of travel that is horizontal and perpendicular to the forward and backward direction of the lawnmower 100. Wheels 2 can be conventional tire wheels or tracked wheels.

[0126] Wheel 2 includes a drive wheel driven by a functional component and a driven wheel driven by the drive wheel. There can be one drive wheel or a pair. The number of wheels 2 can be three or four. When there are three wheels 2, they can include one front wheel and two rear wheels. Preferably, there are four wheels 2, including a pair of front wheels and a pair of rear wheels, with the pair of rear wheels being drive wheels and the pair of front wheels being driven wheels. The rear wheels acting as drive wheels provide better acceleration and climbing ability, and the operator is generally positioned in the middle to rear of the frame 1 for a better operating view. Rear-wheel drive shifts the center of gravity of the lawnmower 100 rearward, making the operator more comfortable.

[0127] The frame 1 is also equipped with a direction control component, a speed control component, and a support structure 7 for supporting the operator. The operator is located on the support structure 7 and operates the direction control component to control the walking direction of the lawnmower 100 and operates the speed control component to control the walking speed of the lawnmower 100.

[0128] Wheel 2 includes a reversing wheel, which can be part of wheel 2 or all of wheel 2. The direction control component controls the reversing wheel to enable the lawnmower 100 to change its direction of travel by turning around the turning radius. The turning radius can be zero, in which case the lawnmower 100 achieves zero-degree turning, that is, it can turn from 0 to 360 degrees on the spot, which can be achieved by turning the wheels in opposite directions while keeping their speeds the same; it can also be a non-zero value, in which case the lawnmower 100 achieves conventional turning, which can be achieved by the difference in wheel speeds, etc. The direction control component can be a steering wheel, which turns the reversing wheel by turning the steering wheel; or it can be a direction control lever, which turns the reversing wheel by operating the direction control lever.

[0129] In one embodiment, the direction control component is a steering wheel, and the wheels 2 include a pair of front wheels and a pair of rear wheels. The reversing wheels are a pair of front wheels. Controlling the pair of front wheels achieves a conventional steering with a non-zero turning radius. In another embodiment, the direction control component is a direction control lever, and the wheels 2 include a pair of front wheels and a pair of rear wheels, all of which are reversing wheels. Zero-degree steering can be achieved by controlling all reversing wheels, or conventional steering can be selected. Preferably, when achieving both zero-degree and conventional steering, the operator manipulates the direction control lever using two different operating methods. However, this is not limited to this; there can also be two direction control levers, one for zero-degree steering and the other for conventional steering. The combination of the direction control component and the reversing wheels is not limited to the two mentioned above and can also include other combinations. Furthermore, the direction control component also includes a structure for enabling the lawnmower 100 to move backward.

[0130] The speed control component controlling the lawnmower 100 can be in the form of a foot-operated pedal or a manually controlled speed control lever; there is no limitation on this. For example, when the speed control component only includes a pedal assembly, the pedal assembly can include an accelerator pedal and a brake pedal. When the speed control component only includes a speed control lever, acceleration and braking functions can be achieved simultaneously through a single speed control lever, or acceleration and braking functions can be achieved separately through two different speed control levers. The speed control component can also be a combination of a pedal and a speed control lever, including a speed control lever for acceleration and a pedal for braking.

[0131] The lawnmower 100 can achieve stepless speed adjustment through the speed control component, but it is not limited to this. The frame 1 can also be equipped with a gear component, which limits the low, medium and high speeds. The lawnmower 100 can adjust the speed within the set low, medium and high speeds through the speed control component.

[0132] The support structure 7 can be a seat, allowing the operator to sit and operate the machine more conveniently. Alternatively, the support structure 7 can be a standing platform, allowing the operator to stand on it. In this case, since a seat is not required, the structure of the lawnmower 100 can be more compact, simpler, and less expensive.

[0133] In one embodiment, the speed control components are an accelerator pedal and a brake pedal, the support structure 7 is a seat, and the direction control components are a steering wheel, making it more convenient for the operator to operate while seated.

[0134] In other embodiments, the direction control component is a direction control lever, which simplifies the structure of the lawnmower 100 compared to a structure with a steering wheel; the speed control component includes a speed control lever for controlling acceleration, and when the support structure 7 is a seat, the speed control component also includes a pedal for braking; when the support structure 7 is a standing platform, the speed control component also includes another speed control lever for braking, thus avoiding the situation where the operator cannot stand steadily because they need to operate with their feet on the standing platform.

[0135] The aforementioned direction control components and speed control components are all mechanical structures, but are not limited to these. The lawnmower 100 may also include a control panel, and the direction control components and speed control components may include electronic structures. The control panel is connected to the electronic structures to electronically control the walking direction and speed of the lawnmower 100.

[0136] like Figure 4 As shown, there can be one or more cutting elements 16, installed below the frame 1, to realize the mowing function of the lawnmower 100. Preferably, the cutting element 16 adopts a double-blade disc structure to ensure its cutting performance. The lawnmower 100 also includes a cutting control component and a height adjustment component. The operator controls the opening and closing of the cutting element 16 and the rotation speed of the cutting element 16 through the cutting control component, and controls the cutting height of the cutting element 16 through the height adjustment component. The cutting control component can be implemented by setting a mechanical gear switch or through a control panel, which is not limited here.

[0137] The functional components include motors that power the wheels 2 and the cutting element 16, respectively. The motors are DC motors with a rated voltage between 36V and 230V, such as 36V, 60V, 80V, 120V, 160V, and 230V. Furthermore, brushless DC motors are preferred due to their longer overall lifespan.

[0138] Specifically, the motor consists of a walking motor 4 and a cutting motor 9. The walking motor 4 drives the wheels to enable the lawnmower 100 to move, while the cutting motor 9 drives the cutting element 16 to enable the lawnmower 100 to cut. The two motors operate independently. Furthermore, the control of the cutting function and the control of the walking function of the lawnmower 100 are independent and do not interfere with each other. That is, the lawnmower 100 can move without cutting, move while cutting, or cut without moving. The cutting motor 9 may include one or more motors. The total output power of the walking motor 4 is no more than 2500W, and the total output power of the cutting motor 9 is no more than 4000W. Preferably, the lawnmower 100 also includes a safety switch. Control of the cutting and walking functions can only be achieved after the safety switch is closed, preventing user injury due to accidental operation.

[0139] A grass collection box is also provided at the rear of the frame 1 to collect grass clippings produced by the cutting component 16. The grass collection box is detachable from the frame 1 to facilitate the operator's disposal of the grass clippings.

[0140] The power source is a DC power source adapted to a DC motor, comprising a first power module 5 installed within the frame and at least one second power module 6 detachably mounted to the frame. The lawnmower 100 is configured to be powered solely by the first power module 5, solely by the second power module 6, or simultaneously by both the first power module 5 and the second power module 6. The first power module 5 and the second power module 6 can be connected in parallel in the circuit, or independently in the circuit, or they can be connected in series.

[0141] Specifically, the first power module 5 is fixedly installed inside the frame 1, and it is essentially a built-in battery. The first power module can be a single battery pack 51, or multiple battery packs 51. Several battery packs 51 can be independently and selectively connected in series within the first power module 5 to achieve a higher voltage than any single battery pack 51; or several battery packs 51 can be independently and selectively connected in parallel within the first power module 5 to achieve a larger capacity than any single battery pack 51. The battery pack 51 is composed of several cells, which can be lithium batteries, nickel-metal hydride batteries, nickel-cadmium batteries, graphene batteries, or lithium iron phosphate batteries, etc., without limitation. A single battery pack 51 can hold more power at a lower cost to meet the operating requirements of the lawnmower 100, resulting in better cost-effectiveness. The rated voltage of a single battery pack 51 is 36V-230V, preferably 48V or 80V.

[0142] The second power module 6 is detachably and movablely mounted to the frame 1, and the frame 1 is provided with a power mounting part 13 for receiving the connection of the second power module 6 to provide power. Figure 6As shown, the power supply mounting part 13 is provided with a sliding groove or sliding rail structure 134. The second power module 6 is slidably mounted through the sliding groove or sliding rail structure 134 to achieve the connection between the second power module 6 and the power supply mounting part 13. (See attached diagram) Figure 6 The image shows a sliding rail structure. The power mounting part 13 can be a mounting groove, a receiving cavity for accommodating the second power module 6, or other forms of connecting structure that allows the second power module 6 to be movably mounted on the frame 1. The second power module 6 is provided with a power output port, and the power mounting part 13 is provided with a power input port that mates with the power output port. The power input port may include a terminal block that is electrically connected to the second power module 6. The terminal block includes a base with a mating surface and several connecting terminals fixed in the base. The second power module 6 is mounted in the mounting part, and the power output port of the second power module 6 mates with the mating surface and is electrically connected to the corresponding connecting terminals.

[0143] In some embodiments, the power supply mounting part 13 includes a pull-out housing 61 that can be slidably pulled out on the frame 1, with the power input port located inside the pull-out housing 61, and the second power module 6 installed inside the pull-out housing 61 with the power output port and the power input port electrically connected.

[0144] The detachable form of the second power module 6 from the frame 1 can also be other. For example, the power mounting part 13 can be a docking space on the frame 1 for inserting the second power module 6, with a connection terminal at the bottom of the docking space for electrical connection with the second power module 6. Alternatively, the power mounting part 13 can be a box mounted on the frame, with the second power module detachably installed inside the box. No limitation is made here. However, the design should comprehensively consider factors such as the reliability, convenience, sealing, dustproofing, and waterproofing of the connection between the second power module 6 and the frame 1.

[0145] By adding a second power module, the battery capacity is increased, allowing for a wider mowing range and better battery life. Furthermore, the second power module can be detached from the frame for independent charging, preventing the entire lawnmower from running out of power and being unable to return, making charging more convenient. Additionally, the second power module can be disassembled and used as an independent unit to power different power tools, increasing its utilization rate and improving the user's return on investment.

[0146] The second power module 6 can be an electrical connection between the power output port and the power input port of a single battery pack 62. Preferably, the voltage of a single battery pack 62 is 12-80V, and more preferably, the voltage of a single battery pack 62 is 20V. The second power module 6 can also be a whole composed of several battery packs 62, with several battery packs 62 independently and selectively connected in series within the second power module 6 to obtain a higher voltage than any single battery pack 62; or several battery packs 62 independently and selectively connected in parallel within the second power module 6 to obtain a larger capacity than any single battery pack 62. A single battery pack 62 can be a lithium battery, nickel-metal hydride battery, nickel-cadmium battery, graphene battery, or lithium iron phosphate battery, etc., and is not limited thereto. The rated voltage of the battery pack 62 is 12-80V, preferably 20V.

[0147] Preferably, the second power module 6 includes two battery packs 62, both of which have the same voltage of 20V and are connected in series.

[0148] Preferred, such as Figure 5 As shown, the second power module 6 includes a housing 61, with several battery packs 62 supported inside the housing 61. A power output port is located on the housing 61. The battery packs 62, independently selected for series or parallel connection, output energy through this power output port. Alternatively, the second power module 6 can be single or multiple. When there are multiple second power modules 6, the power mounting part 13 can have multiple power input ports corresponding to the multiple second power modules 6, and the multiple second power modules 6 are respectively mounted on the vehicle frame 1. However, this is not limited to this; the multiple second power modules 6 can be connected into a single unit and then mounted together through one or more power output ports and corresponding power input ports, i.e., the entire unit is mounted on the vehicle frame 1.

[0149] It is understood that the battery packs 62 can be connected in series, in parallel, or partially in series and partially in parallel; the voltages of the battery packs 62 can be the same or different; and the battery packs 62 are independently fixed or detachably supported within the housing 61. For example, if the power source voltage is 80V, the second power module 6 can include four battery packs 62 connected in series with a rated voltage of 20V, and all battery packs 62 are detachably mounted to the housing 61. However, this is not limited to this; the second power module 6 can also include one battery pack 62 with a rated voltage of 40V and two battery packs 62 with a rated voltage of 20V connected in series, with the 40V battery pack 62 fixedly mounted to the housing 61 and the two 20V battery packs 62 detachably mounted to the housing 61. When the battery pack 62 is detachably installed from the housing 61, it can be replaced with a new battery pack 62 after prolonged discharge and wear. Additionally, a single battery pack 62 can be used independently on other tool bodies, improving utilization. This single battery pack 62 is a universal battery pack 62. Preferably, the voltage of the battery packs 62 in the second power module 6 can all be 20V, and several identical battery packs 62 can be combined.

[0150] The connection structure between the battery pack 62 and the housing 61 can be such that the housing 61 has a receiving position, the receiving position has a receiving interface that matches the interface of the battery pack 62, the battery pack 62 is movably or fixedly installed in the receiving position, and the battery pack 62 is electrically connected to the power output port through the receiving interface.

[0151] The second power module 6 can be installed on the lawnmower 100 to power the lawnmower 100, or it can be detached from the lawnmower 100 as an independent unit to power multiple different power tools, such as: lawn mowers, chainsaws, blowers, blow dryers, etc., forming a power sharing system, which improves the utilization rate of the second power module 6 and increases the user's input-output ratio.

[0152] It is understandable that the second power module 6 can be directly installed on the lawnmower 100 to power the lawnmower 100, or it can be detached from the lawnmower 100 as an independent unit to power multiple different power tools, such as lawn mowers, chainsaws, hair dryers, and blow dryers, forming a power-sharing system and improving utilization. That is, the second power module 6 is essentially a universal battery; a single battery pack 62 of the second power module 6 can be universal, powering other power tools, or the entire second power module can be universal, powering other power tools.

[0153] The frame 1 is also equipped with a charging structure for connecting to an external power source to charge the power source. The first power module 5 is configured to be installed on the frame 1 and charged through the charging structure. The second power module 6 is configured to be detached from the frame 1 and charged by a charging device to replenish its energy, or it can be installed on the frame 1 and charged through the charging structure. Thus, the second power module 6 does not need to be frequently removed from the frame 1 for charging, which improves the convenience of using the second power module 6.

[0154] Specifically, the charging structure can include only one charging interface, that is, both the first power module and the second power module can be charged through this one charging interface, making the structure simple; of course, the charging interface can also be the first charging interface 53 and the second charging interface 63, with different charging interfaces charging the first power module 5 and the second power module 6 respectively, and each independent of the others, making the charging management of the first power module 5 and the second power module 6 clearer and more straightforward.

[0155] The first power module 5 supplies power to the walking motor 4 and / or the cutting motor 9, and the second power module supplies power to the walking motor 4 and / or the cutting motor 9. The first power module 5 and the second power module 6 can supply power sequentially or simultaneously to realize the cutting and walking functions of the lawnmower.

[0156] The lawnmower 100 has a first state that simultaneously realizes the walking and cutting functions, and a second state that only realizes the walking function.

[0157] When the lawnmower 100 is in the first state: it can be powered solely by the first power module 5, meaning the first power module 5 drives both the travel motor 4 and the cutting motor 9. Alternatively, it can be powered solely by the second power module 6, meaning the second power module 6 drives both the travel motor 4 and the cutting motor 9. It can also be powered by the first power module 5 and the second power module 6 working together, with the first and second power modules supplying power sequentially; or the first and second power modules supplying power simultaneously. For example, the first power module 5 and the second power module 6 simultaneously provide power to drive the walking motor 4 and the cutting motor 9; or, the first power module 5 first provides power to drive the walking motor 4 and the cutting motor 9, and when the power of the first power module 5 is lower than a certain amount, the first power module 5 stops supplying power, and the second power module 6 provides power to drive the walking motor 4 and the cutting motor 9. This certain amount is a preset value, which can be 10% of the power, 5% of the power, or 0% of the power. In this application, it is limited to not exceeding the preset value; or, the first power module 5 drives the walking motor 4 and the cutting motor 9, and the second power module 6 also drives the walking motor 4 simultaneously; or the first power module 5 drives the cutting motor 9, and the second power module 6 drives the walking motor 4; or the first power module 5 drives the cutting motor 9, and the second power module 6 drives the walking motor 4, and when the power of the second power module 6 is lower than a preset value, the second power module 6 stops supplying power, and the first power module 5 drives the walking motor 4 and the cutting motor 9. These are not limited to the types listed above. Other methods in which the first power module 5 and the second power module 6 provide power when the lawnmower 100 is in the first state are all within the scope of protection of this application.

[0158] When the lawnmower 100 is in the second state: it can be powered solely by the first power module 5, i.e., the first power module 5 drives the walking motor 4. It can also be powered solely by the second power module 6, i.e., the second power module 6 drives the walking motor 4. Alternatively, the first power module 5 and the second power module 6 can work together to provide power; for example, the first power module 5 and the second power module 6 can simultaneously provide power to drive the walking motor 4; or, the first power module 5 can provide power first to drive the walking motor 4, and when the battery level of the first power module 5 falls below a preset value, the first power module 5 stops supplying power, and the second power module 6 provides power to drive the walking motor 4. These are not limited to the methods listed above; other methods that enable the first power module 5 and the second power module 6 to provide power when the lawnmower 100 is in the second state are all within the scope of protection of this application.

[0159] The power supply mode of the lawnmower 100 in the first state and the second state can be a combination of various power supply modes when it is in different states.

[0160] The lawnmower 100 also includes a third state that only performs the cutting function. In this third state, the lawnmower 100 can be powered solely by the first power module 5, i.e., the first power module 5 drives the cutting motor 9. Alternatively, it can be powered solely by the second power module 6, i.e., the second power module 6 drives the cutting motor 9. It can also be powered by the first power module 5 and the second power module 6 working together, for example, the first power module 5 and the second power module 6 simultaneously powering the cutting motor 9; or, the first power module 5 first powers the cutting motor 9, and when the battery level of the first power module 5 falls below a preset value, the first power module 5 stops supplying power, and the second power module 6 powers the cutting motor 9. These are not limited to the methods listed above; other methods where the first power module 5 and the second power module 6 provide power when the lawnmower 100 is in the third state are all within the scope of protection of this application.

[0161] In some embodiments, both the first power module and the second power module can supply power to the walking motor 4 and the cutting motor 9. Specifically, both can supply power simultaneously, or the first power module can supply power first, and then stop supplying power when the power level is lower than a preset value, and the second power module supplies power.

[0162] Specifically, when the lawnmower is configured to be in the first state, the first power module 5 and the second power module 6 provide power simultaneously; when it is in the second state, the first power module 5 and the second power module 6 provide power simultaneously.

[0163] In addition, the lawnmower can also be configured such that, in the first state, the first power module 5 and the second power module 6 simultaneously provide power; and in the second state, the second power module 6 provides power. Not limited to the above two configurations, other combinations of the first, second, and third states that enable both the first power module 5 and the second power module 6 to power the walking motor 4 and the cutting motor 9 are also within the scope of this application.

[0164] Preferably, the second power module 6 is suitable for supplying power to the cutting motor 9 and the travel motor 4 when their power is within a specific range. This can be understood as the second power module 6 having a limited output power, and its output power differing from that of the first power module 5. Specifically, the first power module 5 outputs a higher power than the second power module 6. For optimal lawnmower performance, the cutting motor 9 is preferentially driven by the first power module 5. If the second power module 6 drives the cutting motor 9, certain conditions must be limited, such as power; that is, when the second power module 6 drives the cutting motor 9, the power of the cutting motor 9 decreases.

[0165] In one embodiment, the first power module 5 can supply power to the walking motor 4 and the cutting motor 9, while the second power module 6 can only supply power to the walking motor 4. The first power module and the second power module supply power sequentially, or the first power module and the second power module supply power simultaneously.

[0166] Specifically, the lawnmower 100 is configured such that when it is in the first state, it is powered only by the first power module 5; when it is in the second state, it is powered only by the second power module 6; and when it is in the third state, it is powered only by the first power module 5.

[0167] In addition, the lawnmower 100 can be configured such that, in the first state, it is powered by the first power module 5 and the second power module 6; in the second state, it is powered by the first power module 5 first, and when the battery level of the first power module 5 drops below a preset value, it is powered by the second power module 6; and in the third state, it is powered only by the first power module 5.

[0168] Preferably, when the lawnmower 100 is configured in a first state, only the first power module 5 provides power. In a second state, if the battery level of the first power module is not lower than a preset value, the first power module 5 provides power first. If the battery level of the first power module 5 falls below the preset value, the second power module 6 provides power. If the battery level of the first power module falls below the preset value, the second power module 6 provides power, meaning the first power module 5 and the second power module 6 provide power sequentially. If the lawnmower 100 also has a third state, the first power module 5 provides power. The lawnmower 100 also includes a protection unit B, which is used to limit the cutting motor 9 to stop working after the battery level of the first power module 5 falls below the preset value.

[0169] Not limited to the above, other combinations of the first state, second state, and third state that also realize the first power module as the walking motor 4 and the cutting motor 9, and the second power module only powering the walking motor 4, are also within the protection scope of this application.

[0170] In addition, the lawnmower 100 may also include a monitoring circuit for monitoring the power of the first power module 5 and the second power module 6.

[0171] The lawnmower also has an output interface 8 electrically connected to the first power module and / or the second power module. The output interface 8 is configured to output AC110-240V and DC20-120V voltages. Preferably, the output interface 8 is configured to output AC110, AC120, AC230, DC20V, DC40V, DC60V, DC80V, or DC120V. The lawnmower 100 can also supply power and / or charge multiple other electrical devices through the output interface 8. For example, it can charge a mobile phone, charge other tools, or power other tools such as lawn mowers, hair dryers, vacuum cleaners, and chainsaws, thus expanding the application range of these types of tools.

[0172] Specifically, the frame has an output port, which serves as an output electrical interface, capable of directly outputting DC voltage. Alternatively, the output port can be connected to an inverter and buck-boost circuit to output AC voltage. This inverter and buck-boost circuit can be located within the frame, in which case the output port becomes the output electrical interface, directly outputting AC voltage. The inverter and buck-boost circuit can also be located outside the frame, integrated into an accessory structure. This accessory structure can be electrically connected to the output port to output voltage, and its output voltage structure serves as the output electrical interface. In this application, preferably, the inverter and buck-boost circuit is located on an accessory structure. This accessory structure can also be directly connected to the second power module 6 to output AC voltage to power or charge other tools.

[0173] Preferably, the output electrical interface 8 is configured to be electrically connected to the first power module 5. The output electrical interface outputs AC 120V. For example, the rated voltage of the first power module 5 is 80V, and the output electrical interface and the first power module 5 are connected via an inverter and boost circuit to output AC 120V. Alternatively, the rated voltage of the first power module 5 is 160V, and the output electrical interface and the first power module 5 are connected via an inverter and buck circuit to output AC 120V.

[0174] like Figure 7As shown, the lawnmower 100 also includes a control unit A. Control unit A can acquire the power levels of the first power module 5 and the second power module 6, and control the power supply to the first power module 5 and the second power module 6 based on the power level information. Specifically, control unit A includes a cutting control unit W1, connected to the cutting motor 9 to control the cutting motor 9; a walking control unit W2, connected to the walking motor 4 to control the walking motor 4; a first power module control unit W3, connected to the first power module 5 to acquire the power level information of the first power module 5 and control its power supply; and a second power module control unit W4, connected to the second power module 6 to acquire the power level information of the second power module 6 and control its power supply. The cutting control unit W1, the walking control unit W2, the first power module control unit W3, and the second power module control unit W4 are communicatively connected to achieve control of the power supply to the first power module 5 and the second power module 6 based on the power level information.

[0175] In one embodiment, the control unit A stores a preset value for the power level of the first power module 5. When the power level of the first power module 5 is greater than the preset value, the control unit A controls the first power module 5 to supply power, and the control unit A controls the second power module 6 to prevent the second power module 6 from supplying power. When the power level of the first power module 5 is lower than the preset value, the control unit A controls the first power module 5 to prevent the first power module 5 from supplying power, and the control unit A controls the second power module 6 to supply power.

[0176] That is, the control method of the lawnmower 100 is to obtain the power information of the first power module 5 and transmit it to the control unit A; obtain the power information of the second power module 6 and transmit it to the control unit A; the control unit A processes the power information and outputs corresponding instructions to the first power module 5 and the second power module 6. Specifically, the control unit A has a preset value for the power of the first power module 5. The control unit A compares the power information of the first power module 5 with the preset value. When the power of the first power module 5 is greater than the preset value, the control unit A sends an instruction to the second power module 6 to de-supply power; when the power of the first power module 5 is lower than the preset value, the control unit A sends an instruction to the first power module 5 to de-supply power. Preferably, when the power of the first power module 5 is lower than the preset value, the control unit A sends an instruction to the cutting motor 9 to de-operate the cutting motor 9.

[0177] In addition, such as Figure 2As shown, the power source may also include only the second power module 6. The lawnmower 100 drives the walking motor 4 and the cutting motor 9 only through the second power module 6. The only difference from the above embodiment is the absence of the first power module 5; the other structures are the same and will not be described again here. The second power module 6 can be the electrical connection between the power output port and the power input port of a single battery pack 62. Preferably, the voltage of a single battery pack 62 is 12-80V, and more preferably, the voltage of a single battery pack 62 is 20V. The second power module 6 can also be a whole composed of several battery packs 62. Several battery packs 62 can be independently and selectively connected in series within the second power module 6 to obtain a higher voltage for the second power module 6 than any single battery pack 62; or several battery packs 62 can be independently and selectively connected in parallel within the second power module 6 to obtain a larger capacity for the second power module 6 than any single battery pack 62. A single battery pack 62 can be a lithium battery, nickel-metal hydride battery, nickel-cadmium battery, graphene battery, or lithium iron phosphate battery, etc., and is not limited here. The rated voltage of battery pack 62 is between 12-80V, preferably 20V.

[0178] Preferably, the second power module 6 includes two battery packs 62, both of which have the same voltage of 20V and are connected in series.

[0179] Preferably, the second power module 6 includes a housing 61, with a plurality of battery packs 62 supported within the housing 61. A power output port is located on the housing 61. The battery packs 62, independently selected for series or parallel connection, output energy through this power output port. Alternatively, the second power module 6 can be single or multiple. When there are multiple second power modules 6, the power mounting part 13 can be provided with multiple power input ports corresponding to the multiple second power modules 6, and the multiple second power modules 6 are respectively mounted on the vehicle frame 1. However, this is not limited to this; the multiple second power modules 6 can be connected into a single unit and then mounted together through one or more power output ports and corresponding power input ports, i.e., the entire unit is mounted on the vehicle frame 1.

[0180] It is understood that the battery packs 62 can be connected in series, in parallel, or partially in series and partially in parallel; the voltages of the battery packs 62 can be the same or different; and the battery packs 62 are independently fixed or detachably supported within the housing 61. For example, if the power source voltage is 80V, the second power module 6 can include four battery packs 62 connected in series with a rated voltage of 20V, and all battery packs 62 are detachably mounted to the housing 61. However, this is not limited to this; the second power module 6 can also include one battery pack 62 with a rated voltage of 40V and two battery packs 62 with a rated voltage of 20V connected in series, with the 40V battery pack 62 fixedly mounted to the housing 61 and the two 20V battery packs 62 detachably mounted to the housing 61. When the battery pack 62 is detachably installed from the housing 61, it can be replaced with a new battery pack 62 after prolonged discharge and wear. Additionally, a single battery pack 62 can be used independently on other tool bodies, improving utilization. This single battery pack 62 is a universal battery pack 62. Preferably, the voltage of the battery packs 62 in the second power module 6 can all be 20V, and several identical battery packs 62 can be combined.

[0181] The connection structure between the battery pack 62 and the housing 61 can be such that the housing 61 has a receiving position, the receiving position has a receiving interface that matches the interface of the battery pack 62, the battery pack 62 is movably or fixedly installed in the receiving position, and the battery pack 62 is electrically connected to the power output port through the receiving interface.

[0182] The second power module 6 can be installed on the lawnmower 100 to power the lawnmower 100, or it can be detached from the lawnmower 100 as an independent unit to power multiple different power tools, such as: lawn mowers, chainsaws, blowers, blow dryers, etc., forming a power sharing system, which improves the utilization rate of the second power module 6 and increases the user's input-output ratio.

[0183] It is understandable that the second power module 6 can be directly installed on the lawnmower 100 to power the lawnmower 100, or it can be detached from the lawnmower 100 as an independent unit to power multiple different power tools, such as lawn mowers, chainsaws, hair dryers, and blow dryers, forming a power-sharing system and improving utilization. That is, the second power module 6 is essentially a universal battery; a single battery pack 62 of the second power module 6 can be universal, powering other power tools, or the entire second power module can be universal, powering other power tools.

[0184] The frame 1 is also equipped with a charging structure for connecting to an external power source to charge the power source. The second power module 6 is configured to be detached from the frame 1 and charged by the charging equipment, or it can be installed on the frame 1 and charged by the charging structure. Thus, the second power module 6 does not need to be frequently removed from the frame 1 for charging, which improves the convenience of using the second power module 6.

[0185] This application also includes a wheeled mobile vehicle, which differs from the aforementioned lawnmower in that it does not include the cutting component 16. Therefore, the wheeled mobile vehicle has only one operating state: walking. In this walking state, the first power module 5 and the second power module 6 can supply power sequentially; or simultaneously. In one embodiment, the first power module 5 and the second power module 6 supply power sequentially, with the first power module 5 supplying power first. Once the power level reaches a preset value, the first power module 5 stops supplying power, and the second power module 6 begins supplying power. Other solutions are the same as those for the aforementioned lawnmower and will not be described further here.

[0186] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
