[0020] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0021] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0022] In this application, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.

[0023] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0024] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values ​​and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, %, 1% or more) of the indicated value. Numerical values ​​that do not use relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 1 degree, 1 degree or more) added to or subtracted from the indicated angle.

[0025] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0026] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0027] In this application, the terms "controller," "processor," "central processing unit," "CPU," and "MCU" are used interchangeably. When using the unit "controller," "processor," "central processing unit," "CPU," or "MCU" to perform a specific function, unless otherwise stated, these functions may be performed by a single or multiple of the aforementioned units.

[0028] In this application, the terms "device," "module," or "unit" are used to describe devices that can be implemented in hardware or software to perform a specific function.

[0029] In this application, the terms “calculation,” “judgment,” “control,” “determine,” “identify,” etc., refer to the operation and process of a computer system or similar electronic computing device (e.g., controller, processor, etc.).

[0030] like Figure 1 As shown, the electric work equipment disclosed in this application can be operated by a user sitting or standing on it or behind it. For example, the electric work equipment can also be an all-terrain vehicle (UTV). In related technologies, all-terrain vehicles include four-wheeled all-terrain vehicles (ATVs), multi-purpose all-terrain vehicles, and recreational vehicles. The electric work equipment can also be a manned snowplow or an electric motorcycle.

[0031] In some embodiments, the electric working device can also be a hand-push working device, in which the user stands behind the hand-push working device and pushes it to move on the ground.

[0032] In this embodiment, the electric work device is a lawn mowing device, such as a lawnmower 100, used to trim lawns and other vegetation. The directions forward, backward, left, right, up, and down are described as follows: Figure 1 The directions shown are as follows. Specifically, when a user is sitting or standing on the lawnmower 100 located on the ground, the direction the user is facing is defined as forward, the direction behind is defined as rear, the direction to the left is defined as left, the direction to the right is defined as right, the direction closer to the ground is defined as downward, and the direction further away from the ground is defined as upward.

[0033] like Figures 1 to 3 As shown, in this embodiment, the lawnmower 100 is taken as a ride-on lawnmower. The ride-on lawnmower is for the user to ride on and operate. In the following disclosure, the term "ride-on lawnmower 100" will be used to refer to the electric work equipment. Similarly, the term "ride-on lawnmower 100" will be used to refer to the lawnmower. The above designations are for the convenience of the description of the disclosure and do not limit the lawnmower to other products described above, such as a standing lawnmower with a standing platform for the user to stand and operate or a handheld lawnmower operated from behind.

[0034] A ride-on lawnmower 100 includes a main body 10 and a power supply 20. The power supply 20 is located on the main body 10. The power supply 20 includes multiple battery packs 21 configured to power at least one of the drive motors or the mowing motor. Compared to a fuel-powered ride-on lawnmower 100, the electric ride-on lawnmower 100 is more environmentally friendly and energy-efficient. At least one of the multiple battery packs 21 is detachably mounted to a junction of the ride-on lawnmower 100. In some embodiments, the junction includes a battery compartment 22. Optionally, the multiple battery packs 21 are configured to be detachable from the ride-on lawnmower 100 and power other power tools or an all-terrain vehicle 200a. For example, Figure 2The power platform of battery pack 21 is shown. It is understood that battery pack 21 can power the power tools on the power platform. Optionally, the power tools can be garden tools, such as lawnmowers, hair dryers 200b, stand-up lawnmowers 200d, etc. Power tools 200 can also be handheld power tools, such as chainsaws 200e, pruning machines, etc. Power tools can be push-type power tools, such as push snow sweepers, push lawnmowers 200c, etc. Power tools can also be drilling tools, sawing tools, electric garden tools, etc.

[0035] The main body 10 includes a frame 11. The ride-on lawnmower 100 or the main body 10 includes a walking assembly 40, an operating assembly 30, a support assembly 90, and a working assembly 80. The frame 11 extends substantially in the front-to-back direction and is configured to mount the walking assembly 40, the operating assembly 30, the support assembly 90, and the working assembly 80.

[0036] The walking assembly 40 includes a walking wheel set 41 and a drive assembly 42. The walking wheel set 41 supports the main body 10, and the drive assembly 42 is configured to drive the ride-on lawnmower 100 to move. In some embodiments, the walking assembly 40 may also include components such as a walking track that drive the ride-on lawnmower 100 to move. The drive assembly 42 is configured to drive the walking track to move. In this embodiment, the walking wheel set 41 includes a rear walking wheel 411 and a front walking wheel 412. Optionally, the rear walking wheel 411 includes a left rear walking wheel 411L and a right rear walking wheel 411R. The front walking wheel 412 includes a left front walking wheel 412L and a right front walking wheel 412R. The drive assembly 42 includes a walking motor that drives the walking wheels to rotate. The walking motor drives the rear walking wheel 411 or the front walking wheel 412 to rotate, thereby realizing the walking function of the ride-on lawnmower 100. Optionally, the number of walking motors can be one, two, three, or four. For example, the walking assembly 40 includes a first drive wheel and a second drive wheel that receive power from the walking motor and drive the walking mechanism. In this embodiment, the first drive wheel is the left rear walking wheel 411L, and the second drive wheel is the right rear walking wheel 411R. The walking motor includes a first motor 421 that provides driving force to the left rear walking wheel 411L, and a second motor 422 that provides driving force to the right rear walking wheel 411R. For ease of reference, in the following description, the first drive wheel 411L refers to the left rear walking wheel, and the second drive wheel 411R refers to the right rear walking wheel. The walking assembly 40 provides driving force to the first drive wheel 411L and the second drive wheel 411R independently. Optionally, the front walking wheel 412 is configured as a swivel wheel, thereby enabling the ride-on lawnmower 100 to turn in directions other than the forward and backward direction.

[0037] The operating component 30 is operated by the user and instructs the user on desired actions to control the rider-mounted lawnmower 100 to move forward, backward, and turn. The operating component 30 includes control levers. In this embodiment, the operating component 30 includes a first control lever 31 and a second control lever 32. The tilt angle of the first control lever 31 and the second control lever 32 controls the steering and straight-line speed of the rider-mounted lawnmower 100. In other alternative embodiments, the operating component 30 includes a steering wheel, including a standard round steering wheel, a flat-bottomed or flat-topped steering wheel, a rectangular steering wheel, a multi-function steering wheel, a folding steering wheel, a touch-sensitive steering wheel, etc.

[0038] A support assembly 90 is used to support the operator and is mounted on the main body 10. The support assembly 90 includes a seat 91. The seat 91 is mounted to the frame 11 for the user to sit on.

[0039] The working component 80 is installed on the main body 10 of the machine body and is at least partially disposed between the first drive wheel 411L and the second drive wheel 411R. It should be explained that between the first drive wheel 411L and the second drive wheel 411R, the working component 80 can be arranged side by side with the first drive wheel 411L and the second drive wheel 411R in one direction, or the working component 80 can be staggered from the first drive wheel 411L and the second drive wheel 411R. For example, the working component 80 is located in front of the first drive wheel 411L, but at the same time, the working component 80 is still in the area between the first drive wheel 411L and the second drive wheel 411R.

[0040] In this embodiment, the working component 80 is a cutting component, which is installed at the bottom of the frame 11, and at least part of the cutting component is installed between the first drive wheel 411L and the second drive wheel 411R. For example, the cutting component is installed between the rear drive wheel 411 and the front drive wheel 412. For ease of reference, the cutting component 80 will be used to refer to the working component in the following description.

[0041] The cutting assembly 80 includes a cutting element for cutting vegetation and a mowing motor 82 for driving the cutting element. In this embodiment, the cutting element is a mowing blade 81, and the mowing motor 82 is specifically configured as a mowing motor. The term "mowing motor" will be used in the following description, but this is not intended to limit the invention. In this embodiment, the cutting assembly 80 includes multiple mowing blades 81 and mowing motors 82 that drive the mowing blades 81 respectively; that is, the number of mowing motors 82 corresponds to the number of mowing blades 81. In some embodiments, the cutting assembly 80 includes multiple mowing blades 81 and mowing motors 82 that drive the mowing blades 81, wherein there is one mowing motor 82 or the number of mowing motors 82 is less than the number of mowing blades 81; that is, one mowing motor 82 can drive multiple mowing blades 81.

[0042] like Figure 1 and Figure 4 As shown, the assembly also includes a deck assembly 12, which is mounted to the main body 10. The deck assembly 12 includes a mowing deck 120, which is formed or connected to the main body 10 and has a downwardly opening cutting chamber 121. The cutting chamber 121 accommodates at least a portion of the mowing blades 81. The deck assembly 12 includes a top wall 122, side walls 123 extending downward from the top wall 122 and forming a circumferential enclosure, and a downwardly opening. A mowing motor 82 is disposed above the top wall 122, and its output shaft passes through the top wall 122 to drive the mowing blades 81.

[0043] like Figure 1 and Figures 4 to 6 As shown, the system also includes a deck mounting assembly 50 configured to connect the deck assembly 12 to the frame 11. The deck mounting assembly 50 includes at least a first mounting member 51, which includes a first mounting end 511 and a second mounting end 512. Exemplarily, the first mounting end 511 is connected to the deck assembly 12, and the second mounting end 512 is connected to the frame 11. At least one mounting end of the first mounting member 51 is connected via a floating connection, and at least one mounting end of the first mounting member 51 is provided with a buffer mechanism 52. Exemplarily, the same mounting end may employ both a floating connection and a buffer mechanism 52. Exemplarily, a mounting end may use only a floating connection or only have a buffer mechanism 52. Exemplarily, a mounting end may not use a floating connection and may not have a buffer mechanism 52. For example, when the second mounting end 512 is floatingly connected to the frame 11, the floating connection is defined as allowing relative displacement between the second mounting end 512 and the frame 11 within a certain range in one or more directions, but the connection between the second mounting end 512 and the frame 11 is not broken. It is understood that even when relative displacement occurs between the second mounting end 512 and the frame 11, the transmission of force or torque still exists within the allowable displacement range. The directions of relative displacement include axial, radial, or angular.

[0044] In this embodiment, the mounting end refers to the location or area used for fixing or connecting, and the mounting end is not necessarily a mounting structure. It can be understood that the first mounting end 511 is defined as: when the deck assembly 12 is connected to the first mounting member 51 via a mounting structure, the location and area of ​​the mounting structure on the first mounting member 51 is the first mounting end 511. The first mounting end 511 can be a mounting point or a location area (this location area covers the mounting structure). The second mounting end 512 is defined as: when the frame 11 is connected to the first mounting member 51 via another mounting structure, the location and area of ​​its mounting structure on the first mounting member 51 is the second mounting end 512. The second mounting end 512 can be a mounting point or a location area (this location area covers the mounting structure).

[0045] When operating on uneven lawns, the suspension system of the lawnmower's deck assembly 12 and frame 11 will shake violently due to the undulating ground, resulting in significant mechanical noise. In this embodiment, by using a floating connection at least one mounting end and providing a buffer mechanism 52 at at least one mounting end, the shaking is absorbed, the noise problem is improved, and the operating comfort is significantly enhanced.

[0046] In this embodiment, the cushioning mechanism 52 is configured to absorb the swaying of the first mounting member 51 relative to the deck assembly 12. Exemplarily, the cushioning mechanism 52 includes an elastic element 521. Exemplarily, the cushioning mechanism 52 includes hydraulic cushioning, a spring, or rubber.

[0047] The first mounting component 51 includes a connecting rod 510. A first mounting end 511 and a second mounting end 512 belong to the connecting rod 510. It is understood that one end of the connecting rod 510 is connected to the deck assembly 12, and the other end is connected to the frame 11. In this embodiment, the rear end of the connecting rod 510 is connected to the deck assembly 12, i.e., the rear end of the connecting rod 510 is the first mounting end 511. The front end of the connecting rod 510 is connected to the frame 11, i.e., the front end of the connecting rod 510 is the second mounting end 512. When the deck assembly 12 shakes, the deck assembly 12 causes the connecting rod 510 to displace along its extension direction, thereby absorbing the vibration of the deck assembly 12 and causing the connecting rod 510 to have a relative displacement with respect to the frame 11. In this embodiment, the connecting rod 510 extends in a front-rear direction. For example, the extension direction of the connecting rod 510 forms an angle with the horizontal plane, and the connecting rod 510 extends obliquely in the front-rear direction.

[0048] The main part or most of the body of the connecting rod 510 is configured as a cylindrical metal structure. One end of the connecting rod 510 is the front floating connection frame 11, and the other end is the rear fixed mounting deck assembly 12. In this embodiment, the buffer mechanism 52 is installed at the front end of the connecting rod 510. Figure 5A As shown, the first mounting member 51 further includes a first fixing member 513, mounted on the front end of the connecting rod 510. The first fixing member 513 is configured to limit the connecting rod 510 when it is connected to the frame 11. The first mounting member 51 also includes a second fixing member 514, disposed on the connecting rod 510 and located behind the first fixing member 513. The second fixing member 514 is configured to limit the displacement of the buffer mechanism 52. An elastic member 521 is disposed on the connecting rod 510 between the second fixing member 514 and the first fixing member 513. Exemplarily, the elastic member 521 is sleeved on the connecting rod 510, with its two ends connected to the first fixing member 513 and the second fixing member 514, respectively. The front end of the connecting rod 510 is slidably connected to the first fixing member 513, wherein the first fixing member 513 allows the connecting rod 510 to slide along its extension direction on the first fixing member 513, and the first fixing member 513 at least restricts the radial or perpendicular movement of the first connecting rod 510 to ensure movement stability. The first fixing member 513 is connected to the frame 11; therefore, one end of the buffer mechanism 52 is also indirectly connected to the frame 11, forming a stable support system. Exemplarily, the first fixing member 513 is provided with a hole to accommodate and allow the connecting rod 510 to slide along its extension direction. Exemplarily, the hole includes a circular hole and a slotted hole with a semi-open groove. Exemplarily, the first fixing member 513 and the connecting rod 510 are respectively provided with a key / groove fit structure, a shaft / shoulder fit structure, and a slider / groove fit structure. Exemplarily, the first fixing member 513 is provided with a sliding bearing or sliding bushing to accommodate and allow the connecting rod 510 to slide along its extension direction. Exemplarily, the first fixing member 513 is provided with a linear guide rail to accommodate and allow the connecting rod 510 to slide along its extension direction. In the above embodiments, some of the technical solutions can be used alone, or a combination of several technical solutions can be used.

[0049] like Figure 5A As shown, the first mounting member 51 also includes a third fixing member 515, which is configured to fix the rear end of the connecting rod 510, i.e., the first mounting end 511, to the deck assembly 12. This design allows the swaying of the deck assembly 12 to be transmitted to the connecting rod 510. However, since the connecting rod 510 and the frame 11 are connected by a floating connection, the swaying energy is converted into the axial reciprocating movement of the connecting rod 510 relative to the frame 11, rather than directly causing relative movement between the connecting rod 510 and the deck assembly 12. This prevents the connecting rod 510 from colliding with the deck assembly 12 due to relative movement, reduces swaying noise, and minimizes damage to parts. The buffer mechanism 52, such as an elastic element 521 (or a damping spring or hydraulic damper), further absorbs and attenuates the movement amplitude of the connecting rod 510, thereby reducing swaying noise.

[0050] like Figure 5B As shown, the first mounting member 51 does not have a third fixing member. That is, one end of the connecting rod 510, i.e., the front end, is floatingly connected to the frame 11, and the other end of the connecting rod 510, i.e., the rear end, is floatingly connected to the mounting deck assembly 12. The rear end of the connecting rod 510, i.e., the first mounting end 511, is hooked to the deck assembly 12. The hooking part 124 of the deck assembly 12 is provided with a groove, which allows the connecting rod 510 to slide in the groove along its extension direction. The hooking part 124 at least restricts the radial or perpendicular movement of the first connecting rod 510. It is understandable that the front and rear ends are floatingly connected along the extension direction, which is more conducive to the conversion of swaying energy.

[0051] like Figures 6 to 8 As shown, in this embodiment, the first mounting member 51 is disposed at the front of the deck assembly 12, connecting the front of the deck assembly 12 to the frame 11. Due to the large weight and area of ​​the deck assembly 12, this embodiment also includes a second mounting member 53, disposed at the rear of the deck assembly 12, connecting the rear of the deck assembly 12 to the frame 11, ensuring the installation stability and balance of the deck assembly 12. The second mounting member 53 is located on the outer side of the frame 11. Exemplarily, the second mounting member 53 includes at least two mounting ends 532 and 533, respectively connected to the deck assembly 12 and the frame 11. The second mounting member 53 includes a U-shaped suspension arm 531. Exemplarily, each mounting end is connected to the deck assembly 12 or the frame 11 through at least two side walls of the U-shaped suspension arm 531 to ensure installation stability. The second mounting member 53 has a bend along its length, and its extension path R is non-linear.

[0052] In this embodiment, two first mounting members 51 are provided, respectively located on both sides of the frame 11. Two second mounting members 53 are provided, respectively located on both sides of the frame 11 and on the outer side of the frame 11, ensuring that the span of the connection point is wide enough.

[0053] like Figure 6 and Figures 9 to 11 As shown, it also includes a height adjustment component 54, configured to adjust the height of the deck assembly 12 and the cutting assembly 80 relative to the ground.

[0054] The height adjustment component 54 includes a gear shift component 541 and a linkage component 542. The gear shift component 541 includes an adjusting member 5411 and a limiting member 5412. The adjusting member 5411 is for user operation, and the limiting member 5412 is used to restrict the adjusting member 5411 to a preset gear position. The linkage component 542 connects the gear shift component 541 and the deck component 12. In this embodiment, the linkage component 542 connects the gear shift component 542 and the second mounting member 53. When the user operates the adjusting member 5411, the adjusting member 5411 can move relative to the limiting member 5412 to different preset gear positions. Under the action of the adjusting member 5411, the linkage component 542 will cause the height of the deck component 12 to change, thereby allowing the ride-on lawnmower 100 to have different cutting heights.

[0055] The adjusting member 5411 includes an adjusting handle 5413, a gear position 5414, and a bending portion 5415. The adjusting handle 5413 is for user operation, the gear position 5414 cooperates with the limiting member 5412 to keep the gear position 5414 at a preset gear position, and the bending portion 5415 connects the adjusting handle 5413 and the gear position 5414.

[0056] The limiting member 5412 forms a limiting hole 5416. Multiple limiting structures are formed on the wall of the limiting hole 5416. Each limiting structure has a protrusion 5417 extending in both vertical and horizontal directions. Protrusions 5417 that reduce the opening size are respectively provided on the upper and lower sides of the opening of the limiting hole 5416. The stop portion 5414 enters and exits the limiting hole 5416 from the opening. The stop portion 5414 includes an extension portion 5418 that protrudes from the side wall of the stop portion 5414. A hook portion 5419 with an oblong hole is formed on the extension portion 5418. When the stop portion 5414 enters the limiting hole 5416 at the corresponding height, the hook portion 5419 hooks with the protrusion located below the limiting hole 5416, and the deck assembly 12 stops at the corresponding height. When a shaking occurs, causing the hook part 5419 to bounce upwards unexpectedly, the protrusion 5417 on the upper side of the corresponding limiting hole 5416 enters the hook part 5419 to prevent the hook part 5419 or the stop part 5414 from disengaging from the opening of the limiting hole 5416, resulting in a change in the height of the deck assembly 12 and the cutting assembly.

[0057] like Figure 1 , Figure 6 ,and Figures 12 to 13As shown, the operating assembly 30 has a first operating lever 31 and a second operating lever 32, which are respectively mounted on the main body 10 to control the walking assembly 40's walking state. The first operating lever 31 can be gripped by the user's left hand and can also be considered the left operating lever, while the second operating lever 32 can be gripped by the user's right hand and can also be considered the right operating lever. The riding lawnmower 100 of this application has two sets of operating levers, left and right, and the steering and straight-line speed of the riding lawnmower 100 are controlled by the tilt angle of the left and right operating levers. For example, the rotation angle of the first operating lever 31 and the second operating lever 32 is positively correlated with the walking speed. The rotation angle refers to the angle between the initial position and the current position of the control lever. When the first control lever 31 and the second control lever 32 are in the initial position, the walking speed of the walking component 40 is zero. When the first control lever 31 and the second control lever 32 are in the extreme position (at which time the rotation angle is the maximum), the walking speed of the walking component 40 is the maximum value corresponding to the current driving speed gear. The walking direction of the outdoor walking device 100 is adjusted by making the rotation angles of the first control lever 31 and the second control lever 32 different.

[0058] For example, a first operating lever 31 is connected to a first drive wheel 411L, and a second operating lever 32 is connected to a second drive wheel 411R. For example, the first operating lever 31 is coupled to a first travel motor 421, and the second operating lever 32 is coupled to a second travel motor 422. The first operating lever 31 and the second operating lever 32 independently control the movement of the first drive wheel 411L and the second drive wheel 411R. Optionally, the first operating lever 31 and the second operating lever 32 independently input drive requirements to the first travel motor 421 and the second travel motor 422.

[0059] Taking the second operating lever 32 as an example, the second operating lever 32 includes a handle portion 321 configured to receive the user's hand. The second operating lever 32 also includes a steering lever 322 configured for movably connecting to the frame 11 or the walking assembly 40. They can be welded, bolted, and / or otherwise attached to each other, and the steering lever 322 is operatively coupled to the drive wheel of the outdoor walking device 100 (e.g., the second drive wheel 411R) to provide steering input to that wheel.

[0060] The operating assembly 30 also includes a damper 33, which is connected to the operating lever via a connecting part 34. Taking the second operating lever 32 as an example, the damper 33 is connected to the second operating lever 32. The damper 33 is configured to absorb the sway of the second operating lever 32, and the damper 33 is disposed above the frame 11. The damper 33 is mounted on the upper side of the frame 11. Exemplarily, the damper 33 is disposed on the side of the second mounting member 53. Exemplarily, the damper 33 is closer to the inner side of the frame 11 than the first mounting member 51 and / or the second mounting member 53.

[0061] For example, the damper 33 includes a rod-shaped damper, such as a hydraulic damper, a gas spring damper, a viscous fluid damper, an electromagnetic damper, a friction damper, a magnetorheological damper, and an elastomer damper. In some embodiments, the damper 33 extends in the front-rear direction, and the damper generates compression and extension movements in the front-rear direction. The swaying of the second operating lever 32 is converted to the damper 33 through the connecting part, thereby causing the damper 33 to deform in the front-rear direction, thus absorbing the swaying of the second operating lever 32. One end of the damper 33 is connected to the frame 11, and the other end is connected to the second operating lever 32. Optionally, one end of the damper 33 is connected to the frame 11, and the other end is connected to the connecting part 34.

[0062] In this embodiment, the connecting part 34 includes multiple links and a rotating shaft connecting the links. The connecting part 34 includes a first link 341 connecting the operating lever (taking the second operating lever 32 as an example), a second link 342 connecting one end of the damper 33, and a third link 343 connecting the first link 341 and the second link 342. The first link 341 and the third link 343 are connected by a first rotating shaft 344, and the third link 343 and the second link 342 are connected by a second rotating shaft 345. Rotating shaft connection positions are respectively provided at both ends of the third link 343. The second link 342 and the damper 33 are fixed at an angle by a fastener 346. In some embodiments, the second link 342 and the damper 33 are rotatably connected by the fastener 346. The push and pull force of the operating lever can be efficiently converted into the axial movement of the damper, and the center distance between the first rotating shaft 344 and the second rotating shaft 345 is dynamically optimized to ensure that there is no dead point in the stroke range. Each shaft end is also equipped with an anti-disengagement retaining ring, which ensures the degree of freedom of rotation while preventing the connecting rod from accidentally separating.

[0063] like Figure 1 and 14 As shown, the ride-on lawnmower 100 includes a lighting assembly 60 configured to improve the visibility of the ride-on lawnmower 100. The lighting assembly 60 includes a front lighting assembly 61, which extends in a left-right direction and is disposed at the front of the ride-on lawnmower 100. The light emitted by the front lighting assembly 61 alters the forward visibility environment of the ride-on lawnmower 100.

[0064] The front lighting assembly 61 is connected to the frame 11. In this embodiment, the frame 11 includes a front frame assembly 13 extending laterally and disposed at the front. The front frame assembly 13 forms a receiving space in which the front lighting assembly 61 is at least partially disposed. The front frame assembly 13 protects the front lighting assembly 61 from collisions or scrapes that could damage it. In this embodiment, at least one of the front frame assembly 13 and the front lighting assembly 61 includes a waterproof structure to prevent water or moisture from entering during operation, which could damage the lighting effect of the front lighting assembly 61 or cause an electrical short circuit.

[0065] In this embodiment, the front frame assembly 13 includes a foot pedal 131, a front cover 132, and a front crossbeam 133. The foot pedal 131 is located in front of the seat 91 and supports the user's feet. The foot pedal 131 is connected to the frame 11, exemplarily, by fasteners. The front cover 132 forms the front portion of the ride-on lawnmower 100, and light emitted from the front lighting assembly 61 is projected to the outside through the front cover 132. The front cover 132 covers the upper side of the front crossbeam 133. In this embodiment, the front cover 132 includes a metal portion 1321 and a plastic portion 1322, wherein the metal portion 1321 is formed or connected to the foot pedal 131, and the plastic portion 1322 is connected to the front crossbeam 133. For example, the foot pedal 131 is formed by bending a sheet of metal. A portion of the metal sheet of the foot pedal 131 is bent towards the front, at least partially covering the plastic portion 1322, thereby increasing the strength of the front cover 132. The plastic portion 1322 includes a main body 1323 and a decorative portion 1324. The main body 1323 has a lighting hole 1325, allowing the front lighting assembly 61 to be exposed to the outside through the lighting hole 1325. The decorative portion 1324 is connected to the main body 1323, and for example, the decorative portion 1324 is connected between the front lighting assembly 61 and the lighting hole 1325. The front frame 11 also includes a support plate 134, which extends vertically and is connected to the front crossbeam 133. The support plate 134 is fixedly connected to the front crossbeam 133 to support the front cover 132, and the support plate 134 and the front cover 132 form a receiving space to accommodate the front lighting assembly 61.

[0066] The front lighting assembly 61 includes a light panel 611, a first lampshade 612, and a second lampshade 613. The light panel 611 includes light-emitting diode (LED) chips, or COB (Chip On Board) chips. The number of LED chips and the distance between adjacent LED chips can be adjusted as needed. The first lampshade 612 is connected to the light panel 611 and is a transparent lampshade. Exemplarily, the first lampshade 612 and the light panel 611 are waterproofed and sealed using polyurethane (PU) or other chemical foaming materials. The first lampshade 612 is connected to the front cover 132. Exemplarily, the first lampshade 612 is connected to the plastic portion 1322 and exposed through the lighting hole 1325. The second lampshade 613 is disposed inside the first lampshade 612, i.e., between the first lampshade 612 and the light panel 611. Exemplarily, the second lampshade 613 is a black lampshade.

[0067] like Figure 3 , Figure 14 As shown, the ride-on lawnmower 100 also includes a control module 70, which acts as a control hub to control the operation of all components electrically connected to the control module 70 throughout the ride-on lawnmower 100. Figures 16 to 19 As shown, the control module 70 includes multiple control boards 72, each equipped with a controller capable of controlling at least the walking assembly 40 and the cutting assembly 80. The control board 72 includes a PCB (Printed Circuit Board) and an FPC (Flexible Printed Circuit Board). The controller employs a dedicated control chip, such as a microcontroller or a microcontroller unit (MCU). The controller includes a processor and a memory. The processor is configured to programmably control and implement its corresponding functions, and the memory stores the program to be executed and related data. It should be noted that the control chip can be integrated into the controller or can be set up independently of the controller. The structural relationship between the driver chip and the controller is not limited in this embodiment.

[0068] In this embodiment, the main body 10 includes a placement area 710 for at least one control board 72. The placement area 710 is divided by features 713 to define a first chamber 711 and a second chamber 712. Multiple control boards 72 are arranged in the first chamber 711, and non-control components are arranged in the second chamber 712. The non-control components include at least one electromagnetic compatibility (EMC) component 73. The EMC component 73 includes a magnetic ring.

[0069] When a lawnmower is mowing, it operates under load, and the electromagnetic compatibility (EMC) requirements for the motor control system are becoming increasingly stringent. The control module must ensure that EMC performance meets relevant standards while also being able to stably output large currents. However, in related technologies, the wiring harness routing and space occupied by connection ports result in a less compact internal layout and lower integration. This design flaw not only affects the stability of current output but may also adversely affect the overall performance of the motor, potentially leading to system failure or EMC exceeding limits. In this embodiment, a cleverly designed partition feature 713 is used in the placement area 710 to divide the entire space into two functional areas: a first chamber 711 and a second chamber 712. The first chamber 711 is specifically designed for integrating multiple control circuit boards. By optimizing the spacing between the circuit boards and the wiring paths, good signal integrity is ensured while improving space utilization. The second chamber 712 is used to house various non-control components, such as heat dissipation devices, filtering components, and other auxiliary devices. This partitioned design offers several advantages: First, the clear division of functional areas makes thermal management more efficient, significantly improving the overall heat dissipation performance of the control box. Second, by integrating non-control components into the main control box, the need for a separate external control box for these components, as required by traditional designs, is completely eliminated, simplifying the system structure and reducing the number of parts and manufacturing costs. This highly integrated solution not only improves product reliability but also leaves ample room for future functional expansion.

[0070] In this embodiment, the control module further includes a positive terminal distribution board 74. The positive terminal distribution board 74 connects the positive lines 741 of multiple control boards 72 to form the total positive terminal of the control module 70. The positive terminal distribution board 74 is disposed within the second chamber 712, and an electromagnetic compatibility element 73 is used to suppress electromagnetic interference from the positive lines 741. The positive terminal distribution board 74 is disposed inside the placement area 710. The total positive line is connected to the positive terminal 742 of each control board 72 through the positive terminal distribution board 74 and the positive lines 741 of each control board 72. The wiring harness is centrally arranged, reducing the space occupied by the wiring harness and reducing the overall placement area 710 of the control module 70. For example, the wiring harness crimping method replaces the use of a junction box.

[0071] like Figure 16 and Figure 17As shown, the control module 70 also includes a negative conductive plate 75, configured to electrically connect the negative terminals 751 of multiple control boards 72. The negative conductive plate 75 is a strip-shaped conductive plate, with the multiple control boards 72 distributed on both sides of the negative conductive plate 75 along its length. The strip-shaped arrangement of the negative conductive plate 75 effectively reduces the size of the negative plate, and the distribution of the multiple control boards 72 on both sides of the strip-shaped negative conductive plate 75 makes the wiring harness routing more regular, avoids cross-interference, and reduces the risk of electromagnetic interference (EMI). For example, the negative conductive plate 75 is made of a high-conductivity aluminum alloy (such as 5052 or 6061).

[0072] In this embodiment, the terminals 723 of the three-phase wiring harness 724 of the control module 70 are located on one side of the control board 72 and arranged in a straight line. The outgoing direction of the three-phase wiring harness 724 is perpendicular to the straight edge of its control board 72. The outgoing side of the negative wire (not shown) and the outgoing side of the three-phase wiring harness 724 are respectively on both sides of the control board 72. Consequently, the negative terminal 751 of the negative wire (not shown) is arranged in a straight line. This straight arrangement can effectively reduce the size of the negative plate, maintain uniform power supply to each module, and improve the stability of cutting and walking performance.

[0073] like Figure 16 and Figure 18 As shown, the control module 70 includes a control box 71, within which a placement area 710 is formed. In this embodiment, the first chamber 711 and the second chamber 712 are disposed within the same control box 71. By cleverly incorporating a partition feature 713 into the control box 71, the space within the control box 71 is divided into two functional areas: the first chamber 711 and the second chamber 712. Integrating multiple control circuit boards and various non-control components into a single control box 71 provides a highly integrated solution that not only improves product reliability but also reserves ample space for future functional expansion.

[0074] In this embodiment, the control box 71 is mounted on the frame 11, and exemplaryly, at least a portion of the control box 71 is disposed under the seat 91. The control box 71 can be formed in various shapes or have multiple shapes, and is made of a material with high thermal conductivity and specific heat capacity, such as aluminum, zinc-aluminum, zinc-aluminum-magnesium, copper, or similar materials. Optionally, the control box 71 is made of aluminum or an aluminum alloy casting. The control box 71 should have a robust structure to prevent deformation or damage when an object impacts the cover. In other embodiments, the control box 71 is made of plastic material to ensure effective heat dissipation of the control module 70 during its operation.

[0075] The placement area 710 within the control box 71 is defined by a dividing feature 713 as a first chamber 711 and a second chamber 712. Exemplarily, the dividing feature 713 is a thin-walled feature protruding from the sidewall of the control box 71, dividing the space within the control box 71 into regions through continuous or discontinuous thin-walled features. Exemplarily, the dividing feature 713 is a placement groove or protruding placement platform feature formed on the control box 71, dividing the space of the control box 71 into regions through grooves or protrusions forming region boundaries. Exemplarily, the control box 71 includes multiple spliced ​​housings, which are spliced ​​to form joints or joining structures, used for control and internal region division. Exemplarily, the dividing feature 713 of the control box 71 can be an indicator feature connected or attached to the housing, such as a line, a sticker, or etching, dividing the space within the control box 71 into regions through the indicator feature. Of course, the dividing feature 713 also includes other technical features that are easily conceived under the inspiration of the above technical solutions, but are not exhaustively listed.

[0076] In this embodiment, the control module 70 includes multiple cutting control boards 721 and multiple walking control boards 722. The cutting control boards 721 are equipped with cutting controllers configured to control the operation of the mowing motors via corresponding drive circuits. The walking control boards 722 are equipped with walking controllers configured to control the operation of the walking motors via corresponding drive circuits. For example, there are two walking control boards 722 and three mowing control boards 721. It can be understood that the five boards are independent of each other. The two walking control boards 722 are identical, and the three mowing control boards 721 are identical. In one embodiment, the drive circuit may be a three-phase bridge driver circuit including six controllable semiconductor power devices (e.g., field-effect transistors (FETs), bipolar junction transistors (BJTs), insulated-gate bipolar transistors (IGBTs), etc.). It is understood that the aforementioned switching elements may also be any other type of solid-state switch, such as IGBTs, BJTs, etc. In some embodiments, both the cutting controller and the walking controller employ vector control. In some embodiments, the cutting controller and the travel controller employ different control methods to control the motor operation. For example, the cutting controller may use vector control and the travel controller may use direct torque control; or, the cutting controller may use direct torque control and the travel controller may use vector control; or, the cutting controller may use vector control and the travel controller may use square wave control; or, the cutting controller may use square wave control and the travel controller may use vector control; or, the cutting controller may use square wave control and the travel controller may use direct torque control; or, the cutting controller may use direct torque control and the travel controller may use square wave control. Since square wave control is a traditional control technology, it will not be elaborated upon here. Under square wave control, the controller can adjust pulse width modulation (PWM), or the conduction angle, lead angle, etc., according to the allocated target torque.

[0077] The first chamber 711 is configured as a semi-enclosed chamber, such as a U-shaped chamber. The second chamber 712 is located inside the opening of the semi-enclosed chamber and is close to the opening end of the semi-enclosed chamber. For example, the U-shaped opening of the U-shaped chamber. The cutting control plate 721 is arranged side by side on one side of the semi-enclosed chamber. The travel control plate 722 is symmetrically arranged on both sides of the semi-enclosed chamber. For example, the cutting control plate 721 is arranged side by side at the bottom of the U-shape of the U-shaped chamber, and the travel control plate 722 is symmetrically arranged on both sides of the U-shaped chamber. The travel control plate 722 has a first connection end 7221 for connecting to the travel motor, and the cutting control plate 721 has a second connection end 7211 for connecting to the cutting motor. The lead-out direction of the second connection end 7211 faces the bottom of the U-shape, and the lead-out direction of the first connection end 7221 faces the opening direction of the U-shape. That is, the lead-out direction of the first connection end 7221 is opposite to the lead-out direction of the second connection end 7211. In this embodiment, multiple control boards 72 are distributed on both sides of the negative electrode conductive plate 75 along its length. For example, a cutting control board 721 is arranged on one side of the negative electrode conductive plate 75, and a walking control board 722 is arranged on the other side of the negative electrode conductive plate 75. A positive electrode branching board 74 is disposed at the U-shaped opening.

[0078] like Figure 16 and Figure 19 As shown, the control module 70 also includes a signal harness 725, which comprises a harness body 7251 and harness branches 7252 branching off from the harness body 7251. Multiple control boards 72 are distributed on both sides of the harness body 7251 to communicate with different harness branches 7252. The extension direction of the harness body 7251 is substantially the same as the extension direction of the negative conductive plate 75. The signal harness 725 is arranged in a cross configuration with the power lines (positive line 741, negative line (not shown)), at least the positive line 741 of the control board 72 is arranged in a cross configuration with the signal harness 725.

[0079] In this embodiment, as Figure 16 As shown, the control box 71 is also provided with a water leakage hole 714, which is located on the lower side of the control board 72, so that water can be safely drained after accidental water ingress into the control box 71.

[0080] An overcurrent protection device 726 is provided on the control board 72. One end of the overcurrent protection device 726 is connected to the control board 72, and the other end is fixed to the mounting area 710; a limiting structure for limiting the overcurrent protection device 726 is provided in the mounting area 710. Exemplarily, the overcurrent protection device 726 includes a fuse configured to protect the drive circuit from current overload, preventing damage to the circuit or motor, etc. In related technologies, the installation and limiting of the overcurrent protection device 726 are housed in a separate mounting box. In this embodiment, the separate fuse mounting box is eliminated, and the overcurrent protection device 726, such as a fuse, is installed in the mounting area 710 within the control box 71, reducing the number of components.

[0081] like Figure 14 and Figures 20 to 23 As shown, the ride-on lawnmower 100 also includes a power management module 23, at least partially mounted outside the battery compartment 22, which controls at least the charging and discharging of the battery pack 21. The power management module 23 includes a battery control board 232 and a heat sink 233, with power terminals 234 on the battery control board 232 extending toward the heat sink 233.

[0082] In this embodiment, the power management module 23 includes a power management control box 231, which forms a receiving space. The battery control board 232 is disposed within the receiving space, and the heat sink 233 is at least partially disposed outside the power management control box 231 for heat dissipation.

[0083] The battery control board 232 includes a first circuit board 2321 and a second circuit board 2322. The first circuit board 2321 is equipped with a power management controller (e.g., a power management MCU) and includes a PCB circuit board. The second circuit board 2322 is equipped with power components, such as metal-oxide-semiconductor (MOSFET) transistors. The first circuit board 2321 and the second circuit board 2322 are arranged in a layered configuration; exemplarily, the first circuit board 2321 is located on the upper layer, and the second circuit board 2322 is located on the lower layer. A heat sink 233 is located below the second circuit board 2322. The heat sink 233 includes heat dissipation fins 2331 made of a high thermal conductivity metal (such as aluminum or copper) that extend away from the second circuit board 2322. Exemplarily, the heat dissipation fins 2331 extend downwards, forming multiple sets of parallel, vertically arranged heat dissipation teeth, thereby significantly increasing the contact area with air. The spacing of the heat dissipation fins 2331 is adjusted according to the heat dissipation requirements; the distance between each pair of fins can be the same or different.

[0084] In this embodiment, the first circuit board 2321 uses pin headers 2323 as connection terminals for signal output. In this embodiment, the pin headers 2323 are located on the lower surface of the first circuit board 2321. Exemplarily, the pin headers 2323 are soldered to the lower surface of the first circuit board 2321, and the extension direction of the pin headers 2323 is the same as the extension direction of the heat sink fins 2331. The pin headers 2323 extend at least partially beyond the power management control box 231 to connect to a female connector with cables. Since the pin headers 2323 extend from the power management control box 231 on the same side as the heat sink 233, the corresponding cables extend in the same direction as the heat sink fins 2331, so that the terminals on the battery control board 232 extend towards the heat sink 233.

[0085] In this embodiment, the first circuit board 2321 and the second circuit board 2322 are connected by fasteners 235, which include fastening bolts or screws. A metal guide post 236 is provided between the first circuit board 2321 and the second circuit board 2322. The guide post 236 connects the first circuit board 2321 and the second circuit board 2322, and the fasteners 235 pass through the guide post 236 to secure the first circuit board 2321 and the second circuit board 2322 together. In related technologies, the connecting guide post 236 of the first circuit board 2321 and the second circuit board 2322 is also a terminal post, such as a power supply positive and negative terminal post. In this case, the connection end of the power supply terminal is located on the upper side of the first circuit board 2321, facing inwards, which is inconvenient for wiring.

[0086] In this embodiment, in addition to the guide post 236, it also includes a terminal post 237 configured for wiring, and a copper busbar 238 connecting the guide post 236 and the terminal post 237. The terminal post 237 extends in a direction toward the heat sink 233. The first end 2371 (the upper end in this embodiment) of the terminal post 237 is connected to the guide post 236 via the copper busbar 238. The second end 2372 (the lower end in this embodiment) of the terminal post 237 is configured with a connecting cable (e.g., a positive / negative power supply wire (not shown)). In this embodiment, the second end 2372 of the terminal post 237 is configured as a power supply terminal 234. Exemplarily, the second end 2372 of the terminal post 237 is closer to the heat sink 233 than the first end 2371 of the terminal post 237. The second end 2372 of the terminal post 237 extends out of the power control box 71 on the same side of the heat sink 233. In this embodiment, the wiring direction is rotated by the combination of copper busbar 238 and terminal 237, from the inside facing the battery compartment 22 to the outside facing the heat sink 233, making wiring more convenient.

[0087] In this embodiment, the guide post 236 is fixedly connected to the upper surface of the second circuit board 2322. The first circuit board 2321 has a connection hole, through which the guide post 236 passes and is connected to the copper busbar 238 via a fastener 235. In this embodiment, the guide post 236 is made of aluminum alloy. The terminal block 237 is limited by the power management control box 231, and the terminal block 237 is also made of aluminum alloy. For example, the terminal block 237 and the guide post 236 are arranged substantially parallel, or at an angle.

[0088] In this embodiment, the second end 2372 (the lower end in this embodiment) is connected to the cable via a flexible conductive part 76. The power terminal 234 is connected to the cable via the flexible conductive part 76. The flexible conductive part 76 significantly improves mechanical adaptability while ensuring electrical performance. The flexible conductive part 76 adopts a special structural design, which can effectively isolate the mechanical vibration generated during equipment operation and prevent connection loosening or metal fatigue fracture caused by continuous vibration. It is suitable for connection scenarios with relative movement or large installation tolerances.

[0089] For example, such as Figure 24 As shown, the flexible conductive part 76 includes a copper braided strip / braided wire connecting piece 76A, which is formed by the warp and weft braiding of the braided wire to form a flexible conductor with three-dimensional degrees of freedom. When there is a height difference between the two ends of the connection, the braided structure can achieve height compensation through its own deformation. When there is an angle between the fixed surfaces, each strand of the braided wire can slide and adjust independently to adapt to a certain angle of planar deflection.

[0090] like Figure 25 As shown, the flexible conductive part 76 includes a layered flexible connecting sheet 76B, which is constructed by interleaved stacking of phosphor bronze sheets. Displacement is absorbed through the synergistic deformation of multiple thin sheets, making it particularly suitable for applications requiring multi-directional compensation. The flexible conductive part 76 offers the advantage of relatively free and compact layout compared to wire harnesses in its application scenarios. In this embodiment, the flexible conductive part 76 uses a copper braided tape / braided wire connecting sheet 76A.
