[0056] 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] 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.).

[0066] like Figures 1 to 5 As shown, this application discloses a standing work machine, which allows a user to stand on it and operate it to perform targeted operations, such as mowing lawns, vegetation, washing ground, or clearing snow. In this embodiment, the standing work machine is exemplified by a standing lawnmower 100. The standing lawnmower 100 allows a user to stand on it and operate it to mow lawns and other vegetation. In the disclosure of this specification, the directions forward, backward, left, right, up, and down are described as... Figure 1 The directions shown are defined as follows: When a user stands on the standing lawnmower 100 located on the ground, the direction facing the user is defined as forward, the direction with their back to the ground is defined as backward, the direction to their left is defined as left, the direction to their right is defined as right, the direction closest to the ground is defined as downward, and the direction furthest from the ground is defined as upward. The technical solution in this application can also be applied to other standing work machines besides the standing lawnmower 100, such as standing snow sweepers and standing washing machines.

[0067] The standing lawnmower 100 includes a power supply 20, a main body 10, a central control mechanism 50, and a support mechanism 90. The main body 10 serves as the main part of the standing lawnmower 100, and the power supply 20, the central control mechanism 50, and the support mechanism 90 are formed on or connected to the main body 10.

[0068] The power source 20 includes a plurality of battery packs 21 configured to power at least one walk motor or mowing motor. At least one of the battery packs 21 is detachably mounted to a junction of the stand-up lawnmower 100. In some embodiments, the junction includes a battery compartment 22. Optionally, the battery packs 21 are configured to be detachable from the stand-up lawnmower 100 and power a power tool or all-terrain vehicle 200a. For example, Figure 2 The 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, ride-on 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.

[0069] Continue to refer to Figure 1 The main body 10 includes a frame 11, a cutting assembly 80, a traveling assembly 40, and a control assembly 70. The frame 11 is used to mount the cutting assembly 80, the traveling assembly 40, the central control mechanism 50, and the support mechanism 90.

[0070] like Figure 4 As shown, the cutting assembly 80 includes a mowing element for mowing grass and a mowing motor 82 for driving the mowing element. In this embodiment, the mowing element is a mowing blade 81, and the mowing motor 82 is specifically configured as a mowing motor. In the following, the mowing motor 82 will be used instead of the mowing motor, but this should not be regarded as a limitation of the present invention.

[0071] In some embodiments, the cutting assembly 80 includes a plurality of mowing blades 81 and mowing motors 82 that drive the mowing blades 81 respectively; that is, there are multiple mowing motors 82. In some embodiments, the cutting assembly 80 includes a plurality of 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.

[0072] like Figure 3As shown, the walking assembly 40 supports the main body 10 and is configured to drive the standing lawnmower 100 to move. The walking assembly 40 includes walking wheels 411 and 412 and a walking motor 42. In this embodiment, the walking assembly 40 includes at least two walking wheels, namely a rear walking wheel 411 and a front walking wheel 412. Optionally, the cutting assembly 80 is mounted on the bottom of the frame 11 and located between the front walking wheel 412 and the rear walking wheel 411. 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 walking motor 42 drives the rear walking wheel 411 or the front walking wheel 412 to rotate, thereby realizing the walking function of the standing lawnmower 100. Optionally, the number of walking motors 42 can be one, two, three, or four. In this embodiment, the number of travel motors 42 is at least two. For example, there are two travel motors 42, which drive the left rear travel wheel 411L and the right rear travel wheel 411R respectively. For example, the left rear travel wheel 411L and the right rear travel wheel 411R are the drive wheels of the standing lawnmower. Optionally, the front travel wheel 412 is configured as a swivel wheel, allowing the standing lawnmower 100 to turn in directions other than the forward / backward direction. For ease of reference, the travel motor 42 driving the left rear travel wheel 411L is designated as the first travel motor 42L, and the travel motor 42 driving the right rear travel wheel 411R is designated as the second travel motor 42R. In some embodiments, the travel motor 42 can be a hub motor or a wheel-side motor.

[0073] In this embodiment, the power supply 20 is configured to supply power to at least the walking assembly 40, so that the drive wheels output torque to drive the standing lawnmower. The ratio of the maximum output torque of a single drive wheel (e.g., the left rear drive wheel 411L or the right rear drive wheel 411R) to the total unloaded weight of the standing lawnmower 100 is greater than or equal to 1.2 N·m / kg. In this embodiment, the first walking motor 42L drives the left rear drive wheel 411L, and the second walking motor 42R drives the right rear drive wheel 411R. It is understood that a single drive wheel includes either the left rear drive wheel 411L or the right rear drive wheel 411R. For ease of reference, the following description of a single drive wheel will use the left rear drive wheel 411L as an example. In some embodiments, the ratio of the maximum output torque of a single drive wheel 411L to the total unloaded weight of the standing lawnmower 100 is greater than or equal to 1.1 N·m / kg. In some embodiments, the ratio of the maximum output torque of a single drive wheel 411L to the unloaded weight of the standing lawnmower 100 is greater than or equal to 1.0 N·m / kg. In some embodiments, the ratio of the maximum output torque of a single drive wheel 411L to the unloaded weight of the standing lawnmower 100 is greater than or equal to 1.3 N·m / kg. In some embodiments, the ratio of the maximum output torque of a single drive wheel 411L to the unloaded weight of the standing lawnmower 100 is greater than or equal to 1.4 N·m / kg. In this embodiment, the ratio of the maximum output power of a single drive wheel 411L to the unloaded weight of the machine is greater than or equal to 8.7 W / kg. In some embodiments, the ratio of the maximum output power of a single drive wheel 411L to the unloaded weight of the machine is greater than or equal to 8.6 W / kg. In some embodiments, the ratio of the maximum output power of a single drive wheel 411L to the unloaded weight of the machine is greater than or equal to 8.5 W / kg. In some embodiments, the ratio of the maximum output power of a single drive wheel 411L to the unloaded weight of the entire machine is greater than or equal to 8.8 W / Kg. In some embodiments, the ratio of the maximum output power of a single drive wheel 411L to the unloaded weight of the entire machine is greater than or equal to 8.9 W / Kg. In some embodiments, the ratio of the maximum output power of a single drive wheel 411L to the unloaded weight of the entire machine is greater than or equal to 9.0 W / Kg. It should be explained that the unloaded weight of the standing lawnmower 100 is defined as the weight of the standing lawnmower 100 when all the battery packs 21 that can be accommodated in the battery compartment 22 are installed and no user is present.

[0074] As an outdoor mobile device, the stand-up lawnmower 100 is used for mowing on slopes and other challenging conditions. When working on slopes, the walking assembly 40 of the stand-up lawnmower 100 needs to provide sufficient traction so that it can overcome its own weight and stably ascend the slope. Simultaneously, the walking assembly 40 also needs to ensure the stability of the stand-up lawnmower 100 during travel, preventing the vehicle from slipping and losing control. In this embodiment, by defining the ratio of the maximum output torque of a single drive wheel 411L of the walking assembly 40 to the unloaded weight of the standing lawnmower 100, the maximum output torque of the drive wheel that can be received per unit weight of the standing lawnmower 100 is defined. The larger the ratio of the maximum output torque of a single drive wheel 411L to the unloaded weight of the standing lawnmower 100, the more maximum output torque of the drive wheel that can be received per unit weight will be. This can be interpreted as the walking motor 42 of the standing lawnmower 100 having a strong driving force and the standing lawnmower 100 having a more reasonable overall weight. In this embodiment, the maximum output power of a single drive wheel 411L of the walking assembly 40 is defined as the ratio of the total unloaded weight of the standing lawnmower 100. This defines the maximum output power that the standing lawnmower 100 can receive per unit weight of the drive wheel. The larger the ratio of the maximum output torque of a single drive wheel 411L to the total unloaded weight of the standing lawnmower 100, the more maximum output power can be received per unit weight of the drive wheel. This can be interpreted as the walking motor of the standing lawnmower 100 having strong driving force and the standing lawnmower 100 having a more reasonable overall weight.

[0075] In this embodiment, the walking assembly 40 includes at least two drive wheels (i.e., the left rear walking wheel 411L and the right rear walking wheel 411R). The ratio of the rated output power of the walking assembly 40 to the unloaded weight of the entire machine is greater than or equal to 7 W / Kg. In some embodiments, the ratio of the rated output power of the walking assembly 40 to the unloaded weight of the entire machine is greater than or equal to 7.1 W / Kg. In some embodiments, the ratio of the rated output power of the walking assembly 40 to the unloaded weight of the standing lawnmower 100 is greater than or equal to 7.2 W / Kg. In this embodiment, by defining the ratio of the rated output power of the walking assembly 40 to the unloaded weight of the standing lawnmower 100, it can be understood as the push-to-weight ratio of the standing lawnmower 100. The larger the push-to-weight ratio, the more driving force the driving wheels (411L, 411R) can be received per unit weight of the standing lawnmower 100, which can indicate that the driving force of the walking motor of the standing lawnmower 100 is strong and the weight of the standing lawnmower 100 is more reasonable. It needs to be explained that the unloaded weight of the stand-up lawnmower 100 is defined as the weight of the stand-up lawnmower 100 when all the battery packs 21 that can be accommodated in the battery compartment 22 of the stand-up lawnmower 100 are installed and no user is carrying it.

[0076] like Figures 3 to 5 As shown, the left front traveling wheel 412L and the right front traveling wheel 412R rotate around the front axis 403, and the left rear traveling wheel 411L and the right rear traveling wheel 411R rotate around the rear axis 402. It should be explained that the front axis 403 is the line connecting the rotation axes of the left front traveling wheel 412L and the right front traveling wheel 412R; the front axis 403 is not necessarily the center line of the solid axis. For example, Figure 5 As shown, the wheelbase L of the vehicle is the distance between the front axle 403 and the rear axle 402. When the machine is unloaded, the ratio of the distance L1 (the distance from the center of gravity M of the standing lawnmower 100 to the rear axle 402) to the wheelbase L is greater than or equal to 0.2 and less than or equal to 0.35. When the machine is unloaded, the ratio of the distance L1 (the distance from the center of gravity M of the standing lawnmower 100 to the rear axle 402) to the wheelbase L is greater than or equal to 0.2 and less than or equal to 0.3. When the machine is unloaded, the ratio of the distance L1 (the distance from the center of gravity M of the standing lawnmower 100 to the rear axle 402) to the wheelbase L is greater than or equal to 0.25 and less than or equal to 0.35. This reasonable center of gravity position gives the standing lawnmower better hill-climbing capability.

[0077] The walking assembly 40 further includes a transmission assembly 45 that transmits the driving force of the walking motor 42 to the drive wheels. The transmission assembly 45 is configured to convert or transmit the torque output by the walking motor 42 and transmit the torque to the drive wheels. In this embodiment, the walking motor 42 includes an output shaft extending along a first axis 401. The left rear walking wheel 411L and the right rear walking wheel 411R rotate about a rear axis 402, wherein the first axis 401 is parallel to but does not coincide with the rear axis 402. In some embodiments, the first axis 401 and the rear axis 402 coincide. In this embodiment, the transmission assembly 45 is configured as a reduction mechanism, for example, a gear transmission assembly 45 for speed reduction and torque amplification. Therefore, the output torque of the walking motor multiplied by the transmission ratio of the transmission assembly equals the output torque of the drive wheels. In some embodiments, when the transmission ratio of the transmission assembly 45 is 1, the output torque of the walking motor is the same as the output torque of the drive wheels.

[0078] like Figure 1 and Figure 6As shown, the support mechanism 90 includes a standing platform 60 with a standing surface configured to support the operator. The standing platform 60 is located at the rear of the frame 11, connected to the frame 11, and positioned between the two rear wheels 411. When the user stands on the standing platform 60 of the support mechanism 90 and operates the standing lawnmower 100, the standing lawnmower 100 is in a borne state. When the standing lawnmower 100 is in the borne state, the weight distributed to the front wheels 412 accounts for 20% to 30% of the total weight of the machine. In some embodiments, when the standing lawnmower 100 is in the borne state, the weight distributed to the front wheels 412 accounts for 24% to 27% of the total weight of the machine. Since different user weights affect the overall weight of the machine in the borne state, a user weight of 90 kg is uniformly defined. It can be understood that the unloaded weight of the standing lawnmower 100 plus 90 kg is the overall weight of the machine in the borne state. When the standing lawnmower 100 switches from an unloaded state to a loaded state, the user's weight mainly increases near the rear wheels 411. Therefore, the overall center of gravity of the standing lawnmower 100 changes, such as... Figure 6 As shown, when the machine is in a manned state, the ratio of the distance L1' from the center of gravity M' of the standing lawnmower 100 to the rear axle 402 to the wheelbase of the vehicle is greater than or equal to 0.2 and less than or equal to 0.3.

[0079] In this embodiment, the stand-up lawnmower 100 has a reasonable setting of the output power and output torque of the drive wheels 411L and 412L, providing a higher output torque and output power than related products in terms of the relationship with the unloaded mass. The relationship between the center of gravity and the rear walking wheel 411 that provides driving force is also reasonably set, ensuring the ability of the stand-up lawnmower 100 to travel and work on slopes. The stand-up lawnmower 100 provided in this embodiment has a straight-line travel capability of no more than 3 meters within 50 meters in the slope width direction on slopes with an inclination angle of no more than 20°.

[0080] In this embodiment, the rear drive wheel 411 includes a left rear drive wheel 411L and a right rear drive wheel 411R. The left rear drive wheel 411L and the right rear drive wheel 411R are each configured with a size of 23×10.5-12. The output torque of a single drive wheel 411L is greater than or equal to 360 N·m. In some embodiments, the output torque of a single drive wheel 411L is greater than or equal to 370 N·m. In some embodiments, the output torque of a single drive wheel 411L is greater than or equal to 380 N·m.

[0081] Continue to refer to Figure 1 and Figures 7 to 14As shown, the standing platform 60 is exemplarily a foot pedal 61, which is located at the rear of the frame 11, connected to the frame 11, and positioned between the two rear wheels 411. A damper 62 is provided between the foot pedal 61 and the frame 11, and the damping value of the damper 62 is greater than or equal to 500 N·s / m. In some embodiments, the damper 62 is provided between the foot pedal 61 and the frame 11, and the damping value of the damper 62 is greater than or equal to 1000 N·s / m. In some embodiments, the damper 62 is provided between the foot pedal 61 and the frame 11, and the damping value of the damper 62 is greater than or equal to 1500 N·s / m. In some embodiments, the damper 62 is provided between the foot pedal 61 and the frame 11, and the damping value of the damper 62 is greater than or equal to 2000 N·s / m. In some embodiments, a damper 62 is provided between the foot pedal 61 and the frame 11, and the damping value of the damper 62 is greater than or equal to 2500 N·s / m. In some embodiments, a damper 62 is provided between the foot pedal 61 and the frame 11, and the damping value of the damper 62 is greater than or equal to 3000 N·s / m. In some embodiments, a damper 62 is provided between the foot pedal 61 and the frame 11, and the damping value of the damper 62 is greater than or equal to 3500 N·s / m. In some embodiments, a damper 62 is provided between the foot pedal 61 and the frame 11, and the damping value of the damper 62 is greater than or equal to 4000 N·s / m. The damper 62 connects the foot pedal 61 and the frame 11. Unlike outdoor work machines with seats, the user of the standing lawnmower 100 needs to stand on the foot pedal 61 to operate the machine. During prolonged standing, the comfort of the foot pedal 61 in supporting the user's feet is required. When the standing lawnmower 100 travels on bumpy roads, the foot pedal 61 vibrates with the overall vehicle, causing significant impact on the user. This affects operation and observation, and also poses a safety hazard. In this embodiment, a damper 62 connects the foot pedal 61 to the frame 11. The damper 62 provides resistance to reduce the vibration of the foot pedal 61 along with the frame 11. The damper 62 provides a damping value of at least 500 N·s / m for better vibration attenuation. If the damping value is too small, it will not achieve the desired vibration reduction; if the damping value is too large, the foot pedal 61 will become too stiff. Furthermore, once the damping value of the damper 62 is balanced with the overall force on the foot pedal 61, the degree of vibration attenuation will gradually decrease. Even if the damping value is further increased, the increase in vibration reduction effect may actually decrease.

[0082] A support plate 615 is disposed below the foot pedal 61, and an elastic component 63 is disposed between the foot pedal 61 and the support plate 615. In some embodiments, the standing platform 60 includes at least one set of elastic components 63, which are symmetrically distributed about the axis of the damper 62. For example, when the standing platform 60 includes one set of elastic components 63, the elastic components 63 themselves are symmetrical about the axis of the damper 62, that is, the central axis of the elastic component 63 coincides with the axis of the damper 63. For example, the standing platform 60 includes two or more sets of elastic components 63, which are symmetrically distributed about the axis of the damper 62. In some embodiments, the standing platform 60 includes elastic components 63, which are substantially centrally disposed relative to the foot pedal 61. For example, the standing platform 60 includes one set of elastic components 63, which are disposed on the axis of the foot pedal 61. In this embodiment, the damper 62 and the elastic component 63 are respectively connected to the front and rear sides of the foot pedal 61 in the front-rear direction. In some embodiments, the damper 62 and the elastic component 63 are staggered in the front-to-back direction. In this embodiment, the damper 62 provides better vertical vibration attenuation, and the elastic component 63 under the foot pedal 61 balances the weight of the human body, achieving a better vibration reduction effect. In this embodiment, the elastic component 63 includes a first elastic component 63a disposed on the left side of the damper 62 and a second elastic component 63b disposed on the right side of the damper 62. The first elastic component 63a and the second elastic component 63b are respectively composed of compression elastic elements, such as compression springs.

[0083] like Figure 9 As shown, the foot pedal 61 is rotatably connected to the frame 11 via a first rotating shaft 618. The centerline of the first rotating shaft 618 is the third axis 601, wherein the third axis 601 and the rear axis 402 of the drive wheel are arranged parallel to each other. When the user stands on the foot pedal 61 of the standing lawnmower 100, the foot pedal 61 assembly is in a static equilibrium state. In this state, the selection calculation is performed, and the load is the user's weight G. In this embodiment, the user's weight is uniformly defined as 90 kg. Under static equilibrium:

[0084]

[0085] Where J is the moment of inertia of the foot pedal 61, a is the angular acceleration of the foot pedal 61, and S... G F is the vertical distance from the user's standing center of gravity to the third axis 601. c The damping force provided to damper 62, l is the lever arm of damper 62; F k The elastic force provided by the elastic component 63, S kThe lever arm of the elastic force. Under the above static equilibrium, the elastic component 63 mainly plays a supporting role, balancing the weight of the person. Secondly, the elastic component 63 provides some resistance to isolate vibration. The damper 62 plays a damping role, mainly used to absorb the vibration energy of the foot pedal 61.

[0086] The resistance provided by damper 62 is adjusted by adjusting the lever arm of damper 62. In the unloaded state, i.e., when the user is not standing on foot pedal 61, according to the formula:

[0087]

[0088] like Figure 10 As shown, l is the lever arm of the damper 62, s is the vertical distance from the connection point of the first end 621 of the damper 62 to the frame 11 to the third axis 601, and α is the tilt angle of the damper 62.

[0089] In this embodiment, s is taken as a fixed value, that is, the vertical distance from the connection point of the first end 621 of the damper 62 to the frame 11 to the third axis 601 is not changed. The lever arm of the damper 62 is adjusted by adjusting the tilt angle α of the damper 62. The frame 11 includes a crossbeam 113, the foot pedal 61 includes a connecting piece 611, the first end 621 of the damper 62 is connected to the crossbeam 113, and the second end 622 is connected to the connecting piece 611. The connecting piece 611 is detachably connected to the damper 62. Figure 12 As shown, the connecting piece 611 includes multiple connection points 614. When the second end 622 of the damper 62 is connected to any one of the connection points 614, the damper 62 has different tilt angles α. The lever arm of the damper 62 is adjusted by changing the connection position of the damper 62. For example, the second end 622 of the damper 62 is connected to the connection point 614 by a detachable fastener, such as a bolt and nut. For example, the connecting piece 611 includes two plate-like structures, including a first connecting plate 612 and a second connecting plate 613, which are respectively disposed on the left and right sides of the damper 62. Taking the first connecting plate 612 as an example, multiple connection points 614 are arranged on the first connecting plate 612 along the horizontal and vertical directions respectively. The opening direction of the connection point 614 extends in the left-right direction.

[0090] like Figure 13 As shown, in this embodiment, the connecting piece 611 is disposed inside the foot pedal 61, that is, when projected in the vertical direction, the orthographic projection of the connecting piece 611 is located within the orthographic projection of the foot pedal 61. In some embodiments, such as Figure 14As shown, the connecting piece 611 extends out of the foot pedal 61, and the second end 622 of the damper 62 is connected to the front side of the foot pedal 61. That is to say, when projected in the vertical direction, the orthographic projection of the connecting piece 611 is outside the orthographic projection of the foot pedal 61; for example, when projected in the vertical direction, the orthographic projection of the connecting piece 611 is in front of the orthographic projection of the foot pedal 61. By placing the connecting piece 611 outside the foot pedal 61 and fixing the damper 62 to the outside of the frame 11 and the foot pedal 61, more standing space is provided for the user, and the damper 62 does not obstruct the user's standing position.

[0091] In some embodiments, the lever arm of the damper 62 is adjusted by adjusting the vertical distance from the connection point of the first end 621 of the damper 62 to the third axis 601 of the frame 11. For example, the damper 62 is detachably connected to the crossbeam 113 of the frame 11, and the crossbeam 113 has multiple connection points (not shown) at different heights, thereby adjusting the lever arm of the damper 62 by changing its connection position.

[0092] like Figure 10 As shown. The angle β between the foot pedal 61 and the horizontal plane is defined as follows: In the unloaded state, i.e., when the user is not standing on the foot pedal 61, the angle β0 between the foot pedal 61 and the horizontal plane is defined as the initial position angle β0 of the foot pedal 61. The movement angle of the foot pedal 61 during passenger transport and driving is less than or equal to -10°, that is, β0 - 10 ≤ β ≤ β0. This is to ensure that the foot pedal 61 will not bottom out during driving. In this embodiment, β0 is greater than or equal to 10°, for example, β0 is defined as 15°. When the user's weight is 60kg to 90kg, when the foot pedal 61 is in the passenger transport state, β is greater than or equal to 5° and less than or equal to 10°. Figure 8 As shown, the vertical height from the highest point of the foot pedal 61 to the ground is defined as the distance of the pedal from the ground. In the unloaded state, that is, when the user is not standing on the foot pedal 61, the initial distance from the ground is H0. The initial distance from the ground H0 is greater than or equal to 200mm. For example, the initial distance from the ground H0 is 250mm.

[0093] like Figures 9 to 14As shown, taking the first elastic component 63a as an example, the first elastic component 63a includes a first elastic element 631 and a second elastic element 632, which are distributed along the front-to-back direction of the standing lawnmower 100. For example, the first elastic element 631 and the second elastic element 632 are staggered front-to-back. Optionally, the first elastic element 631 and the second elastic element 632 include at least two specifications of compression springs. Two compression springs of different specifications are used. Optionally, the first elastic element 631 and the second elastic element 632 include two compression springs of the same specification. In the unloaded state, the first elastic element 631 and the second elastic element 632 are respectively connected to the foot pedal, and the first elastic element 631 and the second elastic element 632 have different heights. This allows either the first elastic element 631 or the second elastic element 632 to provide support for the user when the load is less than a preset value, adapting to users of different weights. When the user's weight is low, only one compression spring is subjected to the load of the user's weight. When the user is heavy, the two compression springs are respectively subjected to the load of the user's weight. The preset value of the load can be pre-set and cannot be adjusted or set by the user. In some embodiments, the preset value of the load can be adjusted by the user, who can adjust the preset value of the load according to changes in the user's weight and load. For example, the first elastic element 631 and the second elastic element 632 provide different stiffnesses; the first elastic element 631 is positioned in front of the second elastic element 632, and the stiffness of the first elastic element 631 is greater than that of the second elastic element 632. For example, the first elastic element 631 and the second elastic element 632 provide the same stiffness, but their unloaded heights are different.

[0094] Since the second elastic element 632 component is symmetrically arranged with the first elastic element 631 component and has a basically the same structure, the structure of the second elastic element 632 component will not be described in detail.

[0095] In this embodiment, the standing platform 60 uses a combination of separately configured dampers 62 and elastic components 63 for vibration reduction. The elastic components 63 mainly provide support and balance the user's weight, while the dampers 62 provide damping and are configured to absorb the vibration energy of the foot pedals 61. The elastic components 63 are symmetrically arranged on both sides of the dampers 62, providing individual support for the user's feet. This allows for individualized support even when the user's feet apply different forces. The elastic components 63 are configured as a multi-spring structure to adapt to different weights, and the dampers 62 are set with appropriate damping values. The supporting force provided by the elastic components 63 and the resistance provided by the dampers 62 work together to achieve a standing lawnmower 100 with all-around shock absorption support suitable for various weights.

[0096] The standing platform 60 also includes a first connector 616 connecting the frame 11 and the foot pedal 61, and a second connector 617 connecting the support plate 615 and the frame 11. One end of the first connector 616 is connected to the crossbeam 113 of the frame 11, and the other end is rotatably connected to the foot pedal 61 via a first pivot 618. In some embodiments, the first connector 616 is formed with the frame 11, and the foot pedal 61 is rotatably connected to the first connector 616 via the first pivot 618. In this embodiment, the first connector 616 extends in a direction perpendicular to the third axis 601; exemplaryly, the first connector 616 extends in a vertical direction. The first connector 616 is symmetrically arranged about the centerline of the damper 62. The second connectors 617 are respectively disposed on the left and right sides of the foot pedal 61, and the second connectors 617 extend in a direction perpendicular to the third axis 601; exemplaryly, the second connectors 617 extend in a vertical direction.

[0097] In another embodiment of this application, the standing platform 60A, such as Figures 15 to 17 As shown, the standing platform 60A is equipped with an adjustment component 80 for adjusting the preload of the damper 62A to match operators of different weights. Among them, with... Figures 7 to 14 Some of the structures or components in the middle standing platform 60 are the same. Figures 15 to 17 The part numbers that are the same in some parts are retained. Figures 7 to 14 The labels in the text.

[0098] When the operator is not standing on the foot pedal 61, i.e., when the foot pedal 61 does not provide support, the foot pedal 61 is in the first position; when the operator stands on the foot pedal 61, the foot pedal 61 rotates around the third axis 601 to the second position. Figure 15 (As shown). The damping element 62A provides resistance to the movement or tendency of the foot pedal 61. During operation, the standing lawnmower swings, causing the operator to swing as well. Since the foot pedal 61 is a floating connection, the damping element 62A can absorb part of the swing of the foot pedal 61, thus achieving the purpose of shock absorption.

[0099] The damping element 62A is equipped with preload, which is the resistance provided by the damping element 62A to the foot pedal 61 when the foot pedal 61 is not supporting the operator (i.e., the foot pedal 61 is in the first position). The preload affects the swing amplitude of the foot pedal 61. Excessive preload may cause the foot pedal 61 to hit its limit, while insufficient preload will reduce the damping effect. Therefore, to achieve optimal damping, the preload provided by the damping element 62A to the foot pedal 61 needs to meet preset conditions. The magnitude of the preload is related to the operator's weight; the supporting force of the foot pedal on the operator is related to the operator's weight. Appropriate preloads need to be matched to operators of different weights to achieve optimal damping.

[0100] The adjusting component 80 operablely adjusts the preload of the damping element 62A so that when the foot pedal 61 supports the operator, the resistance provided by the damper 62A to the foot pedal remains essentially constant despite changes in the supporting force of the foot pedal 61 on the operator. This accommodates operators of different weights, ensuring that the resistance provided by the damper 62A to the foot pedal 61 meets preset conditions for operators of varying weights. By setting the adjusting component 80, the preload of the damper 62A can be adjusted to accommodate operators of different weights, thereby achieving optimal shock absorption for operators of different weights. The adjusting component 80 adjusts the relative position of the foot pedal 61 and the frame so that when the foot pedal 61 is in the first position, the resistance provided by the damper 62A to the foot pedal 61 is adjusted.

[0101] The adjustment assembly 80 includes an elastic element 82 and a setting unit 81. One end of the elastic element 82 is connected to the foot pedal 61, and the other end is connected to the frame 11. The elastic element 82 applies an upward force to the foot pedal 61. The setting unit 81 can set the engagement position of the elastic element 82 on the frame 11, thereby setting the magnitude of the force applied by the elastic element 82 to the foot pedal 61. The elastic element 82 can have multiple engagement positions with the frame 11 to accommodate operators of different weights. When operators of different weights stand on the foot pedal 61, by engaging the elastic element 82 at different engagement positions on the frame 11, the magnitude of the force applied by the elastic element 82 to the foot pedal 61 is set to compensate for the preload of the damping element 62A, so that operators of different weights can achieve approximately the same suspension experience.

[0102] The frame 11 is provided with a plurality of coupling portions 83, which are spaced apart along the height direction of the frame 11. The setting portion 81 selectively engages with one of the coupling portions 83. The plurality of coupling portions 83 may include two or more locations, for example... Figure 15The five positions are shown. Assuming the maximum load-bearing weight of the foot pedal 61 is 100kg, when an operator weighing 100kg stands on the foot pedal 61, the elastic element 82 is engaged with the lowermost engagement part 83, at which point the shock absorption effect of the suspension assembly 70 is optimal; when an operator weighing less than 100kg stands on the foot pedal 61, the engagement position of the elastic element 82 needs to be moved upward to compensate for the preload of the damping element 62A, so that the force on the damping element 62A is equivalent to the force when a 100kg operator stands on the foot pedal 61. For example, when an operator weighing 80kg-100kg stands on the foot pedal 61, the engagement position of the elastic element 82 can be moved up one position from the lowest position; when an operator weighing 60kg-80kg stands on the foot pedal 61, the engagement position of the elastic element 82 can be moved up two positions from the lowest position; when an operator weighing 40kg-60kg stands on the foot pedal 61, the engagement position of the elastic element 82 can be moved up three positions from the lowest position; and when an operator weighing less than 40kg stands on the foot pedal 61, the engagement position of the elastic element 82 can be moved up four positions from the lowest position, that is, moved to the highest position.

[0103] In some embodiments, the connecting portion 83 can be a plug-in portion, such as a plug-in hole, and the setting portion 81 can be a plug-in rod, which is plugged into the plug-in portion. In some embodiments, the connecting portion 83 can be a hook-in portion, such as a hook-in hole, and the setting portion 81 can be a hook, which is hooked into the hook-in portion. In some embodiments, the connecting portion 83 can be a snap-fit ​​portion, such as a snap-fit ​​groove, and the setting portion 81 can be a snap-fit, which is snapped into the snap-fit ​​portion. The above are merely illustrative examples and are not intended to limit the scope of the invention.

[0104] In some embodiments, the limiting member is manually adjustable, meaning the setting part 81 is manually engaged with the corresponding engaging part 83. Since the users of a single standing lawnmower are relatively fixed, a manual adjustment solution is sufficient. In some embodiments, the limiting member is automatically adjustable, for example, a motor and rack can be used to selectively engage one of the setting parts 81 with the engaging part 83.

[0105] In some embodiments, two adjusting components 80 are provided, and the two adjusting components 80 are symmetrically distributed with respect to the damping element 62A. The two adjusting components 80 can be adjusted independently, and the adjustment amounts of the two adjusting components 80 can be the same or different. The two adjusting components 80 can also be adjusted synchronously through a linkage mechanism. In some embodiments, the number of adjusting components 80 is more than two.

[0106] In some embodiments, a support system for a standing work machine is also disclosed. The standing work machine includes a frame 11 and front and rear wheels 421 supporting the frame 11. The support system includes a standing platform 60 and an adjustment assembly 80. The standing platform 60 has at least one foot pedal 61 for supporting the operator. The foot pedal 61 includes a first position when no support force is provided and a second position when supporting the operator. A damper 62A absorbs or buffers at least part of the vibration between the foot pedal 61 and the frame 11. The adjustment assembly 80 is used to adjust the relative position of the foot pedal 61 and the frame 11 so that when the foot pedal 61 is in the first position, the resistance provided by the damper 62A to the foot pedal 61 is adjusted so that the resistance provided by the damper 62A to the foot pedal 61 meets a preset condition.

[0107] like Figures 6 to 8 As shown, the support mechanism 90 also includes a cushion 91, which provides support for the user's body when standing on the foot pedal 61. The user can lean against the cushion 91 to operate the device. In this embodiment, the cushion 91 is tilted forward. When operating, the operator can lean against the cushion 91 for more support, facilitating operation, reducing the risk of falls, and improving operational comfort. In some embodiments, such as... Figure 6 As shown, the angle γ between the cushion 91 and the vertical plane is between 10° and 30°. For example, the angle γ between the cushion 91 and the vertical plane is 20°. That is, when a worker leans against the cushion 91, the angle γ of the vertical plane tilted forward is 20°. Figures 7 to 8 As shown, the vertical distance from the highest point of the backrest 91 to the footrest 61 is defined as H1, where H1 is greater than or equal to 800mm, so that the user can lean comfortably against it. For example, H1 is 900mm. Projecting the standing lawnmower 100 onto the ground from a vertical direction, the footrest extends behind the backrest 91, and the distance W1 between the footrest and the backrest 91 is greater than or equal to 150mm. For example, the distance between the footrest and the backrest 91 is 200mm, so that the user has sufficient standing space.

[0108] In this embodiment, the cushion 91 is detachably connected to the main body 10. The cushion 91 can be removed from the main body 10 during transportation or when cleaning is required. A limiting structure is provided between the cushion 91 and the frame 11. When the cushion 91 needs to be fixed to the main body 10, the limiting structure locks the cushion 91 to the frame 11. When the cushion 91 needs to be removed, the limiting structure is released through an unlocking operation, allowing the cushion 91 to separate from the frame 11. Optionally, the limiting structure includes a movable snap-fit ​​structure, a threaded structure, or a hook-hole structure. The unlocking operation drives the release of the limiting structure, including one-button unlocking, for example, a single press or flick of the limiting structure to transition from the limited state to the released state, and linear release unlocking, for example, the limited state of the limiting structure changes linearly with each operation, switching to the released state. Furthermore, all of the above unlocking operations do not require tools or specialized tools, enabling manual installation and removal of the cushion 91.

[0109] like Figure 20 As shown, the control component 70 controls at least the operating states of the walking motor 42 and the lawnmower motor 82. The control component 70 includes a drive circuit 73 and a controller 72. Exemplarily, the controller 72 employs a dedicated control chip, such as a microcontroller unit (MCU). Specifically, the controller 72 controls the on / off state of the switching elements in the drive circuit 73 through the control chip. Exemplarily, the drive circuit 73 includes power transistors, such as metal-oxide-semiconductor field-effect transistors (MOSFETs). Exemplarily, the controller 72 is mounted on a control circuit board 71, which includes a printed circuit board (PCB) and a flexible printed circuit board (FPC).

[0110] like Figure 1 and Figure 18As shown, in this embodiment, the control component 70 further includes an electrical control box 74, which has a receiving section configured to house the control circuit board 71. The electrical control box 74 is located between the power supply 20 and the standing platform 60. For example, the electrical control box 74 is located above the standing platform 60, behind the battery compartment 22. For example, the electrical control box 74 is located in front of the cushion 91. When the control component 70 malfunctions and needs troubleshooting or maintenance, the control component 70 can be repaired and maintained by removing the cushion 91, improving the convenience of maintenance. The control circuit board 71 inside the electrical control box 74 is equipped with multiple control chips, capacitors, and other electrical components. During the operation of the standing lawnmower 100, a large amount of heat is generated. Overheating of electrical components may damage the components and may also cause the controller 72 to enter the overheat protection program, affecting the use of the product.

[0111] To ensure heat dissipation of the control component 70, the main body 10 also includes a heat dissipation component 741, which includes a fan 742, a pump 744, and a ventilation duct 745. The fan 742 and the pump 744 are connected via a duct 747. The outlet of the pump 744 is connected to the inlet of the ventilation duct 745, and the outlet of the ventilation duct 745 faces the electrical control box 74, forming a heat dissipation airflow path from the fan 742 to the electrical control box 74. In this embodiment, the fan 742 and the pump 744 are respectively located on the left and right sides of the power supply 20. For example, a water vapor separator 746 is provided upstream of the fan 742, and the outlet of the water vapor separator 746 is connected to the fan 742. In this embodiment, the fan 742 is located inside the reversing section. This ensures heat dissipation for the electronic components inside the electrical control box 74.

[0112] like Figures 18 to 22 As shown, the central control mechanism 50 includes a control panel 51 configured for user operation to control the standing lawnmower 100. The control panel 51 is positioned above the foot pedal. An operating unit 52 is provided on the control panel 51, including a left drive lever 52L and a right drive lever 52R. The operating unit 52 is configured for the operator to grip to at least control the walking direction and speed of the standing lawnmower 100. The walking direction of the standing lawnmower 100 includes forward, backward, left turn, and right turn. In some embodiments, the controller 72 outputs control commands based on the actions on the drive levers, including forward / backward commands, turning commands, and zero-turn commands.

[0113] In some embodiments, the operating unit 52 includes a left drive lever 52L and a right drive lever 52R, which are configured for the operator to hold with both hands to at least control the walking direction and speed of the standing lawnmower 100. The left drive lever 52L and right drive lever 52R are movably connected to the operating platform housing 511. To ensure that the left drive lever 52L and right drive lever 52R have room to move, the operating platform housing 511 is provided with a track through hole 512 that matches the movement trajectory of the left drive lever 52L and right drive lever 52R. To prevent foreign objects from entering the operating platform 51 through the track through hole 512, a protective part 513 is added to the track through hole 512. Exemplarily, the protective part 513 is a protective net, a protective cover, or other structure. The left drive lever 52L and right drive lever 52R are symmetrically arranged. Taking the right drive lever 52R as an example, the right drive lever 52R is L-shaped, including a vertical part 522 and a horizontal part 521. The vertical part 522 is rotatably mounted on the operating table 51, and the horizontal part 521 intersects the extension direction of the vertical part 522. The horizontal part 521 extends basically horizontally, and the horizontal parts 521 of the left drive lever 52L and the right drive lever 52R extend towards each other. The operator's hands can be gripped on the two horizontal parts 521 respectively to operate the left drive lever 52L and the right drive lever 52R. In some embodiments, the operator can control the standing lawnmower 100 to move forward by simultaneously rotating the left drive lever 52L and the right drive lever 52R forward, and control the standing lawnmower 100 to move backward by simultaneously rotating the left drive lever 52L and the right drive lever 52R backward. Rotating only the left drive lever forward can control the standing lawnmower 100 to turn left, and rotating only the right drive lever forward can control the standing lawnmower 100 to turn right. In some embodiments, the operator can control the walking speed of the standing lawnmower 100 by adjusting the rotation amplitude of the drive lever.

[0114] In some embodiments, the left drive lever 52L and right drive lever 52R are further configured to be operated by the operator to have at least a first position open to both sides and a second position closed to the center. The controller 72 is configured to allow current to flow from the power supply 20 to the travel motor 42 when at least a first signal indicating that the left drive lever 52L and right drive lever 52R have switched from the second position to the first position and a second signal indicating that they have switched from the first position to the second position are detected sequentially. This configuration is intended to ensure safe start-up and prevent the standing lawnmower 100 from moving abruptly due to unintentional touch of the drive levers by the operator.

[0115] The control panel 51 also includes an operator interface, which comprises a display screen 53 with a display plane 53a. In some embodiments, the first plane is defined as substantially parallel to the ground plane where the walking assembly 40 is located. In some embodiments, the left drive lever 52L and the right drive lever 52R are configured for user operation to have at least a first position open to both sides and a second position closed in the middle on the opening and closing plane. In some embodiments, the projections of the left drive lever 52L and the right drive lever 52R on the first plane when in the second position at least partially overlap with the projection of the display plane 53a on the first plane. The opening and closing plane is substantially parallel or substantially perpendicular to the display plane 53a. When the left drive lever 52L and the right drive lever 52R are in the first position, i.e., when the drive levers are open, the display screen 53 can be operated. This configuration makes the structure on the control panel 51 more compact and does not affect the operation of the display screen 53. In this embodiment, as Figure 17 As shown, the distance H2 between the left drive lever 52L and the right drive lever 52R and the upper surface of the control panel 51 is greater than or equal to 130mm. This can be understood as the distance H2 extending beyond the upper surface of the control panel 51 by the left drive lever 52L and the right drive lever 52R is greater than or equal to 130mm. This design is both for user comfort and to effectively prevent the user from touching other control components on the control panel 51 when operating the left drive lever 52L and the right drive lever 52R. In some embodiments, the distance H2 between the left drive lever 52L and the right drive lever 52R and the upper surface of the control panel 51 is greater than or equal to 135mm. In some embodiments, the distance H2 between the left drive lever 52L and the right drive lever 52R and the upper surface of the control panel 51 is greater than or equal to 140mm. In some embodiments, the distance H2 between the left drive lever 52L and the right drive lever 52R and the upper surface of the control panel 51 is equal to 145mm.

[0116] like Figures 19 to 21As shown, in this embodiment, the operating console 51 is movably connected to the frame 11. The operating console 51 includes an operating console housing 511, an operating part 52, and a display screen 53, which are respectively disposed on the operating console housing 511. The operating console has a first position and a second position, and the height of the upper edge of the operating console 51 to the ground plane where the walking component 40 is located is different in the first and second positions. Specifically, when the operating console is in the first position, the entire operating console extends vertically for user use. When the operating console is in the second position, the height of the upper edge of the operating console to the ground plane where the walking component is located is reduced. The height H3 of the upper edge of the operating console 51 to the ground plane where the walking component is located in the second position is less than the height H4 of the upper edge of the operating console 51 to the ground plane where the walking component is located in the first position. For example, when the operating console is in the first position, the operating console is in a working state, and the user stands on the foot pedal 61 to control the walking component through the operating part 52. When the operating console is in the second position, the operating console is in a retracted state, and the operating console cannot be operated by the user to control the walking component. In this embodiment, the operating part 52 extends out of the operating platform housing. Therefore, in some embodiments, when the operating platform 51 is in the working state, the height H4 from the upper edge of the operating part 52 to the ground plane where the walking assembly 40 is located in the vertical direction is greater than or equal to 1100 mm. In some embodiments, when the operating platform 51 is in the working state, the height H4 from the upper edge of the operating part 52 to the ground plane where the walking assembly 40 is located in the vertical direction is greater than or equal to 1200 mm. In this embodiment, when the operating platform 51 is in the working state, the height H4 from the upper edge of the operating part 52 to the ground plane where the walking assembly 40 is located in the vertical direction is equal to 1220 mm. It can be understood that when the operating platform 51 is in the working state, the overall height H4 of the standing lawnmower 100 is greater than or equal to 1100 mm. In this embodiment, when the operating platform 51 is in the working state, the overall height H4 of the standing lawnmower 100 is equal to 1220 mm.

[0117] In this embodiment, the operating console 51 is connected to the frame 11 via an operating console rotation axis 514, and the operating console 51 rotates relative to the frame 11 about the rotation axis. For ease of reference, the rotation axis of the operating console rotation axis 514 is referred to as the fourth axis 501. The operating console 51 rotates relative to the frame 11 about the fourth axis 501. The fourth axis 501 is parallel to the rear axis 402 of the drive wheel. When the operating console 51 switches between the first position and the second position, the operating console 51 rotates about the fourth axis 501, and the operating part 52 and the display screen 53 rotate together with the operating console housing 511. Figure 19 and Figure 20As shown, when the control panel 51 is in the second position, i.e., in the retracted state, the control panel 51 is rotated around the fourth axis 501 toward the foot pedal 61, with the operating part 52 facing the foot pedal 61. For example, the control panel rotation axis 514 is located at the rear of the control panel housing 511. Therefore, when the control panel 51 is operated to the retracted state, the entire control panel 51 flips to the rear of the frame 11, and the operating part 52 is simultaneously flipped to face the foot pedal 61, thereby reducing the overall height of the standing lawnmower 100. When the control panel 51 is in the retracted state, the height H3 from the highest point of the standing lawnmower 100 to the ground plane where the walking assembly 40 is located is less than or equal to 1000 mm. In this embodiment, when the control panel 51 is in the retracted state, the height H3 from the highest point of the standing lawnmower 100 to the ground plane where the walking assembly 40 is located is equal to 950 mm. By rotating the control panel 51, the overall height of the standing lawnmower 100 is reduced by more than 20%, which is beneficial to the container loading rate during the transportation of the standing lawnmower 100.

[0118] In some embodiments, the rotation angle θ of the operating table 51 about the fourth axis 501 is greater than or equal to 90°; in some embodiments, the rotation angle θ of the operating table 51 about the fourth axis 501 is greater than or equal to 100°; in some embodiments, the rotation angle θ of the operating table 51 about the fourth axis 501 is greater than or equal to 110°; in some embodiments, the rotation angle θ of the operating table 51 about the fourth axis 501 is greater than or equal to 120°; in some embodiments, the rotation angle θ of the operating table 51 about the fourth axis 501 is greater than or equal to 130°; in some embodiments, the rotation angle θ of the operating table 51 about the fourth axis 501 is greater than or equal to 140°; and in this embodiment, the rotation angle θ of the operating table 51 about the fourth axis 501 is equal to 150°. When the operating table 51 is in the working state and the stored state, the operating table housing 511 is positioned and connected to the frame 11. For example, a locking member 54 is provided between the operating table housing 511 and the frame 11. The locking element 54 is detachably connected to at least one of the control panel housing 511 and the frame 11. When the control panel 51 switches between the working state and the retracted state, the locking element 54 disengages from at least one of the control panel housing 511 and the frame 11, allowing the control panel housing 511 and the frame 11 to move relative to each other. When the control panel 51 is in the working state or the retracted state, the locking element 54 positions the control panel housing 511 and the frame 11, preventing relative movement between them. This ensures that even when the control panel 51 is in the retracted state, the control panel housing 511 and the frame 11 remain relatively fixed, preventing the control panel from shaking during transportation. For example, the locking element 54 includes a pin 541, and the control panel housing 511 and the frame 11 are respectively provided with positioning holes 542 to accommodate the pin 541. The control panel housing 511 and the frame 11 are respectively provided with positioning holes 542 corresponding to the working state and the retracted state. In some embodiments, the control panel housing 511 and the frame 11 are provided with a plurality of positioning holes 542 so that the control panel housing 511 and the frame 11 can be positioned and connected at multiple angles.

[0119] In some embodiments, an assistive component 543 is provided between the operating table 51 and the frame 11 to assist the user in flipping the operating table 51. Exemplarily, the assistive component 543 includes a hydraulic rod, a gas spring support rod, etc. The assistive component 543 also serves as a buffer in case the operating table 51 collides with the frame 11 during the flipping process.

[0120] like Figures 22 to 23The control panel 51 also includes multiple operating components 77, with the controller 72 connected to each of the operating components 77. In this embodiment, the multiple operating components 77 include an emergency stop switch 771. The controller 72 is configured to send a stop signal to the walking motor 42 and the lawnmower motor 82 when the emergency stop switch 771 is triggered. In this embodiment, the storage module of the controller 72 includes at least two different control methods: automatic mode and manual mode. When the controller 72 is switched to manual mode, the controller 72 outputs control commands based on the actions on the operating unit 53 to control the operating state of the walking motor 42, and the running speed of the lawnmower motor 82 is controlled by the speed regulation module. When the controller 72 is switched to automatic mode, the controller 72 no longer responds to the operation of the operating unit 53 to output control commands. The controller 72 controls the speed of the walking motor 42 and the walking path of the walking component 40 based on preset parameters. The pre-set parameters include, but are not limited to, the following settings: The controller 72 stores multiple operating modes with different fixed parameters at the factory; the user selects a mode but cannot modify the parameters; or the user can adjust given parameters as needed, but the parameter values ​​are multiple specified values, and the user cannot arbitrarily define the values; or the user can arbitrarily adjust the parameter values ​​of the required parameter type to meet customer needs. Understandably, in manual mode, the user needs to constantly provide operating commands to make the standing lawnmower 100 complete its work. In automatic mode, the user only needs to observe and does not need to constantly provide operating commands to control the operation of the standing lawnmower 100. However, if in automatic mode, the standing lawnmower 100 deviates from the prescribed abnormal operating state due to external reasons or a malfunction or abnormality in its own components, the user needs to be able to quickly and urgently stop the movement and mowing work of the standing lawnmower 100 to ensure safety. This application is equipped with an emergency stop switch 771. In the event of an abnormal state, the user can actively trigger the emergency stop switch 771, and the controller 72 will send a stop command to the walking motor 42 and the mowing motor 82. The walking motor 42 and / or the mowing motor 82 that are running will respond to the stop command and stop working quickly. The walking motor 42 or the mowing motor 82 that are not working do not need to respond to the stop command, thus ensuring the safety of the standing lawnmower 100 and the user.

[0121] In this embodiment, when the emergency stop switch 771 is triggered, the controller 72 enters manual mode, and the user takes over the operation and driving of the standing lawnmower 100. This ensures that after an emergency stop, the standing lawnmower 100 is controlled by the user by default upon restarting, and can switch to automatic mode as needed after the user confirms a fault or abnormal contact.

[0122] In some embodiments, when the emergency stop switch 771 is connected between the walking motor 42 and the lawn mowing motor 82 and the battery pack 21, when the emergency stop switch 771 is triggered, the electrical connection between the walking motor 42 and the lawn mowing motor 82 and the battery pack 21 is disconnected, and the walking motor 42 and the lawn mowing motor 82 lose power and stop.

[0123] In some embodiments, when the emergency stop switch 771 is connected between the controller 72 and the walking motor 42 and the mowing motor 82, optionally, when the emergency stop switch 771 is triggered, the controller 72 sends a rapid braking signal to the walking motor 42 and the mowing motor 82, and the walking motor 42 and the mowing motor 82 respond to the rapid braking signal to perform short-circuit braking and motor reverse torque braking.

[0124] like Figure 22 As shown, the emergency stop switch 771 is located on the left side of the main body 10. Optionally, the emergency stop switch 771 is located on the left side of the control panel housing 511. Optionally, the emergency stop switch 771 is located on the left side of the upper side of the control panel housing 511. Optionally, the emergency stop switch 771 is located on the left side of the frame 11 so that the user will not accidentally operate it during normal driving, and it needs to be touched under conscious conditions. In some embodiments, the emergency stop switch 771 is a button. In some embodiments, the emergency stop switch 771 is a knob. In some embodiments, the emergency stop switch 771 is a lever. In some embodiments, the emergency stop switch 771 cannot automatically reset after being triggered by operation.

[0125] In this embodiment, multiple operating components 77 include a start switch 772. When the start switch 772 is activated, the electrical components of the standing lawnmower are powered on or start running. Optionally, the start switch 772 can be a physical switch such as a button, knob, lever, or key. Optionally, the start switch 772 can be an electronic switch with electronic identification functions, such as a contact electronic switch with biometric identification such as password recognition, chip recognition, NTC recognition, facial recognition, or fingerprint recognition. Optionally, the start switch 772 is an electronic switch, and the trigger command of the electronic switch is sent to the start switch 772 through non-contact signal transmission methods such as IoT, Bluetooth, or remote control. In this embodiment, the standing lawnmower 100 has at least two types of start switches 772. Optionally, it includes physical switches and electronic switches with electronic identification functions. Optionally, it includes physical switches and electronic switches with non-contact signal transmission methods. Optionally, it includes all three types of switches mentioned above.

[0126] like Figure 24As shown, in this embodiment, the control component 70 further includes an Electronic Stability Program (ESP) module 75 and an Anti-lock Braking System (ABS) module 76. The ESP system 75 consists of an ESP controller 751, a steering sensor 752 (monitoring the operating mode of the control unit), a drive wheel sensor 753 (monitoring the speed rotation of each drive wheel), a sideslip sensor 754 (monitoring the rotation state of the frame 11 around the vertical axis), and a lateral acceleration sensor 755 (monitoring the centrifugal force when the running gear 40 turns). The ESP controller 751 and controller 72 are configured as dual controllers (e.g., dual MCUs). Optionally, the ESP controller 751 and controller 72 are mounted on the same control circuit board 71; in some embodiments, the ESP controller 751 and controller 72 are mounted on two different circuit boards. The Anti-lock Braking System (ABS) module 76 mainly consists of a drive wheel sensor 761 (monitoring the speed rotation of each drive wheel), a solenoid valve 762 (blocking the pipeline to release part of the pressure in the braking system), a pump 763 (the solenoid valve reduces the pressure in the pipeline, and the pump can restore the pressure), and an ABS controller 764. In some embodiments, the ABS controller 764, ESP controller 751, and controller 72 all use different MCUs. Optionally, the ABS controller 764, ESP controller 751, and controller 72 are disposed on the same control circuit board 71. Optionally, any two of the ABS controller 764, ESP controller 751, and controller 72 are disposed on the same control circuit board 71, and the remaining one is disposed on a separate control circuit board 71. Optionally, the ABS controller 764, ESP controller 751, and controller 72 are disposed on three separate control circuit boards 71, that is, the ABS controller 764, ESP controller 751, and controller 72 are each disposed on a separate circuit board.

[0127] In this embodiment, the control component 70 also includes an energy management system 78 (EMS) for monitoring, controlling and optimizing the energy flow and energy consumption of the power source 20 in the electrical equipment.

[0128] like Figure 25 As shown, the energy management system 78 includes a power management board 781 on which an energy management controller 782 is disposed. Optionally, the power management board 781 is electrically connected to the power supply 20 device and includes at least one energy management controller 782 configured to control the charging or discharging process of multiple battery packs 21 in the power supply 20. The energy management controller 782 employs a dedicated control chip, such as a microcontroller or microcontroller unit (MCU).

[0129] In this embodiment, both the controller 72 and the energy management controller 782 are housed in the electrical control box 74. The controller 72 is configured to include a first control module for controlling the walking motor 42 and a second control module for controlling the lawnmower motor 82. The first and second control modules can be integrated into a single control chip, or multiple control chips can be used separately. The controller 72 and the energy management controller 782 can be integrated on the same control circuit board 71, or they can be set on different control circuit boards 71. However, since all control circuit boards 71 ​​are housed in the electrical control box 74, the integrated layout facilitates maintenance, saves space, and allows for a shared heat dissipation structure.

[0130] In some embodiments, a shock-absorbing device 748 is provided at the connection between the electrical control box 74 and the power management board 781 and the rack 11, configured to reduce the vibration load on the connectors and internal components. Optionally, the shock-absorbing device includes shock-absorbing rubber, silicone, or other elastic shock-absorbing components.

[0131] like Figures 26 to 28 As shown, the main body 10 also includes a height adjustment device 841 configured to adjust the distance between the entire cutting assembly 80 and the ground, and a locking device 842 configured to lock the distance between the entire cutting assembly 80 and the ground. To facilitate height adjustment of the cutting assembly 80 by an operator standing on the lawnmower, the lawnmower is equipped with an adjustment handle 843 extending outside the frame 11. The adjustment handle 843 is movably connected to the frame 11, and its height is greater than or equal to the height of the operating section 53. The adjustment handle 843 is located on the right side of the main body 10, allowing the user, standing on the standing platform 60, to operate the adjustment handle 843 to drive the height adjustment device 841 to adjust the height of the cutting assembly 80, and simultaneously operate the adjustment handle 843 to drive the locking device 842 to lock the distance of the cutting assembly 80. In some embodiments, the adjustment handle 843 is detachably connected to the frame 11. For example, the handle and frame 11 have multiple mounting positions, with different mounting positions allowing the handle to have different mounting angles or heights relative to the frame 11, adapting to the user's height and operating habits. When the control panel 51 is in the retracted state, the adjustment handle 843 is disassembled and stored to reduce packaging space. In some embodiments, the adjustment handle is configured as a telescopic or folding structure, and when the control panel 51 is in the retracted state, the adjustment handle 843 is folded or retracted to reduce size and thus reduce packaging space.

[0132] The cutting assembly 80 includes a mowing deck 83 having a downward-facing cutting chamber 831 configured as a mowing blade. A mowing motor 82 is mounted on the mowing deck 83. Part of the mowing motor 82 extends out of the cutting chamber 831; optionally, part of the mowing motor 82 is located above the mowing deck 83. The mowing deck 83 is connected to a frame 11 and to a height adjustment device 841. Optionally, the mowing deck 83 is provided with mounting structures 832, wherein multiple identical mounting structures 832 are provided on the mowing deck 83, so that only one type of fastening structure is needed for installation, facilitating installation. In this embodiment, the mowing deck 83 is connected to the frame 11 and to the height adjustment device 841 using six fasteners; optionally, the fasteners are bolts.

[0133] In some embodiments, an active adjustment mechanism 833 is also included. The active adjustment mechanism 833 includes an attitude sensor 834 disposed on the main body 10 and a mowing deck 83 angle adjustment assembly 835. The attitude sensor 834 is configured to detect the real-time attitude of the main body 10 and is disposed on the frame 11. Optionally, the attitude sensor 834 may include a three-axis gyroscope, a three-axis accelerometer, a three-axis electronic compass, or other motion sensors. The mowing deck 83 angle adjustment assembly 835 is connected to the mowing deck 83. The attitude sensor 834 detects the real-time attitude of the frame 11 and sends the attitude information to the controller 72 in the form of a signal. The controller 72 determines the vehicle body swaying caused by potholes or stones on the ground based on the attitude information. When the vehicle body is swaying, the controller 72 sends a corresponding angle adjustment signal to the mowing deck 83 angle adjustment assembly 835. The mowing deck 83 angle adjustment assembly 835 adjusts the angle or swaying degree of the mowing deck 83 according to the control information, filtering out or reducing the amplitude of swaying to ensure the flatness of the cutting quality.

[0134] like Figure 3 and Figure 26 As shown, the frame 11 includes a front frame 111 and a rear frame 112. Front wheels 412 are mounted on the front frame 111, and rear wheels 411 are mounted on the rear frame 112. Different working environments require different cutting components 80, and different sizes of cutting components 80, such as 48-inch and 50-inch, require different assembly spaces. The front frame 111 and rear frame 112 are detachably connected, allowing adjustment of the lawnmower's wheelbase to obtain different bottom assembly spaces and meet the adaptation needs of different cutting components 80.

[0135] The front frame 111 is U-shaped and includes a second crossbeam 114. Both ends of the second crossbeam 114 have forward-extending first connecting portions 115, each equipped with a front travel wheel 412. The front travel wheel 412 is preferably a swivel wheel. In one embodiment, the front end of the first connecting portion 115 has an assembly tube 116, inside which a first bearing is assembled. A first rotating shaft is interference-fitted within the first bearing. The lower end of the first rotating shaft extends out of the assembly tube 116 and connects to a front fork. The front travel wheel 412 is rotatably connected to the front fork. The front fork has a wheel guard plate, the front end of which extends beyond the front travel wheel 412. In the event of a collision, the wheel guard plate collides with the obstacle before the front travel wheel 412, preventing the front travel wheel 412 tire from colliding with the obstacle. This is especially important when the obstacle is hard, preventing damage to the front travel wheel 412 tire and extending its service life. As a preferred design, the wheel guards are tilted from top to bottom towards the front of the lawnmower. Compared to the wheel guards being set vertically, the tilted wheel guards and the front wheels 412 are less damaged in the event of a collision, thus improving the collision protection capability.

[0136] like Figure 26 and Figure 28 As shown, the front frame 111 is equipped with a mechanical interface 117 for connecting other devices, including garden tools such as lawnmowers, hair dryers, and walk-behind power tools such as lawnmowers, chainsaws, and cleaning machines. Alternatively, the power tools can be finishing tools such as screwdrivers / drills / wrenches, electric hammers, nail guns, and sanders. Alternatively, the power tools can be sawing tools such as reciprocating saws, jigsaws, and circular saws. Alternatively, the power tools can be grinding tools such as angle grinders and sanders. Alternatively, the power tools can be other types of power tools such as fans. These other devices are connected to the stand-up lawnmower 100 via the mechanical interface 117.

[0137] The front rack 111 is also equipped with an electrical connection interface 118, such as an ETO electrical connection interface. Other devices obtain power from the power supply 20 through the electrical connection interface 118 to power the drive structure in other devices. The electrical connection interface 118 is equipped with a corresponding interface controller 72 and hardware. The interface controller 72 is communicatively connected to the controller 72. Other devices not only obtain power from the power supply 20 through the electrical connection interface 118, but also communicate with the controller 72 through the electrical connection interface 118. In this embodiment, an interactive interface is also configured near the electrical connection interface 118 to receive user commands and provide feedback on the working status.

[0138] In some embodiments, the mechanical interface 117 and the electrical connection interface 118 are disposed on the front side of the front frame 111 and on the second crossbeam 114.

In some embodiments, the mechanical interface 117 and the electrical connection interface 118 are respectively disposed on the front side, left side, or right side of the front frame 111.

[0139] like Figure 26 and Figure 28 and Figure 2 As shown, the main body 10 is equipped with lights in multiple locations, such as taillights and turn signals at the rear, and headlights at the front. These lights serve two purposes: firstly, they provide illumination, facilitating mowing operations in poor lighting conditions and meeting the needs of different usage scenarios; secondly, the different flashing frequencies and colors of the lights can convey different signals, facilitating communication and instruction among staff.

[0140] In this embodiment, the front lighting assembly 31 is disposed above the front frame 111. Exemplarily, the battery compartment 22 is disposed on the front frame 111, and the battery compartment 22 includes a compartment body 221 with a receiving space and an openable cover 222. The front lighting assembly 31 is disposed on the front side of the compartment body 221. In some embodiments, the front lighting assembly 31 is disposed on the side of the cover 222. In the front-rear direction, the front lighting assembly 31 is located on the rear side of the front frame 111 to prevent the front lighting assembly 31 from being impacted. In the vertical direction, the distance between the center of the front lighting assembly 31 and the ground is greater than or equal to 550 mm and less than or equal to 700 mm. In some embodiments, the distance between the center of the front lighting assembly 31 and the ground is greater than or equal to 600 mm and less than or equal to 650 mm. In this embodiment, the distance between the center of the front lighting assembly 31 and the ground is 630 mm.

[0141] A front lighting assembly 31 extends horizontally and is positioned at the front of the electric lawnmower. The light emitted by the front lighting assembly 3114 alters the forward field of vision of the electric lawnmower. The front lighting assembly is approximately U-shaped and is positioned below the cover 222. In this embodiment, a front panel 223 is provided at the front of the battery compartment 221, and the front lighting assembly 31 is fixedly connected to the front panel 223. The front lighting assembly 31 includes a first housing 311, a running light 312, and a headlight 313. The first housing 311 supports the running light 312 and the headlight 313, and the first housing 311 connects the front lighting assembly 31 to the front panel 223 via fasteners. The running light 312 includes LED beads or a light panel; for example, the running light 312 includes LED beads or COB beads. The headlight 313 includes LED beads or a light panel; for example, the headlight 313 includes LED beads or COB beads. The illumination area presented by the front lighting group is 5m long and 4m wide.

[0142] In this embodiment, a left warning light 321 and a right warning light 322 are respectively provided on the left and right sides of the control panel 51. The left warning light 321 and the right warning light 322 are respectively disposed on the control panel housing 511. For example, the left warning light 321 and the right warning light 322 are located below the left operating part 5352L and the right operating part 5352R. For example, the left warning light 321 and the right warning light 322 are respectively located above the cover 222 of the battery compartment 22 and behind the battery compartment 22. For example, the left warning light 321 and the right warning light 322 are substantially flush with the uppermost side of the cushion 91 in the vertical direction. In this embodiment, the left warning light 321 and the right warning light 322 include an LED 323 and a cover 324. The cover 324 includes two colors, red and yellow, and displays different colors when the LED is lit.

[0143] When a user triggers the start switch 772, the driving light 312 illuminates. For example, the driving light 312 includes multiple LEDs spaced apart in the left-right direction, emitting a sequential lighting pattern to indicate the start of the vehicle. For example, the multiple LEDs illuminate sequentially from left to right or right to left for a target duration and then turn off sequentially, forming a sequential lighting pattern to represent the start of the vehicle. It should be noted that the next LED is illuminated before the previous one is turned off; that is, two or more LEDs are illuminated simultaneously.

[0144] When the driving assembly 40 starts driving, the driving lights 312 switch to a state where all or some of the lamps are constantly on to improve the user's visibility.

[0145] In some embodiments, when the mower motor 82 is running, the front lighting assembly 31 can indicate the direction of grass removal when the mower motor 82 is operating. For example, the driving light 312 includes a plurality of LEDs spaced apart in the left-right direction that can emit a flowing light pattern from left to right or from right to left to represent the direction of grass removal. Specifically, after all the LEDs are lit, they sequentially turn off from left to right or from right to left to form a flowing light pattern that indicates the direction of grass removal. In another embodiment, at least some of the LEDs are arranged in a pattern that indicates the direction of grass removal and can be lit simultaneously to indicate the direction of grass removal.

[0146] In some embodiments, the LEDs of the daytime running light 312 can emit a breathing flashing light to indicate that charging is in progress. Specifically, the LEDs illuminate a target number of times at a target frequency, and after each first target duration, they continue to illuminate for a second target duration, where the second target duration is longer than the first target duration. It should be noted that the blinking frequency of the breathing flashing light is lower than that of a rapid flashing light. The daytime running light 312 switches to a state where all or some of the LEDs are constantly on to indicate that charging is complete.

[0147] In some embodiments, the driving light 312 includes a plurality of LEDs spaced apart in the left-right direction, which emit a flowing light pattern from the outside in to indicate that the entire vehicle is off. Specifically, after all the LEDs are lit, they extinguish sequentially from the outermost to the innermost side to form a flowing light pattern that represents the entire vehicle being off. In other embodiments, after all the LEDs are lit, they extinguish sequentially from the innermost to the outermost side to form a flowing light pattern that represents the entire vehicle being off. Of course, the LEDs can also be arranged in multiple rows and columns, radially, or in concentric rings, and after all the LEDs are lit, they extinguish radially from the inside out or from the outside in.

[0148] In some embodiments, the light 313 does not automatically turn on when the entire device is started. When the user needs to turn on the light 313, the user operates the light 313 start switch 772, and the light 313 gradually brightens. When the user turns off the light 313, the user operates the light 313 start switch 772 again, and the light 313 turns off directly.

[0149] In some embodiments, a user triggering the start switch 772 can illuminate the left warning light 321 and the right warning light 322. For example, the left warning light 321 and the right warning light 322 gradually illuminate in increasing brightness. When the driving assembly 40 begins to drive, the driving lights 312 switch to a state where all or some of the LEDs are constantly on.

[0150] In some embodiments, the LEDs of the left warning light 321 and the right warning light 322 can emit rapidly flashing lights to represent alarm or error information. Specifically, the LEDs light up a target number of times at a target frequency and for a target duration each time, forming flashing lights that represent alarm or error information. It should be noted that one LED can flash rapidly, or multiple LEDs can flash rapidly simultaneously, and the flashing frequency of the LEDs is high, with each flash lasting for a short time. The alarm or error information includes the walking component 40, the cutting component 80, and the control component 70.

[0151] In some embodiments, the LEDs of the left warning light 321 and the right warning light 322 can emit a breathing flashing light to indicate that charging is in progress. Specifically, the LEDs light up a target number of times at a target frequency, and after each first target duration, they continue to light up for a second target duration, where the second target duration is longer than the first target duration. It should be noted that the flashing frequency of the breathing flashing light is lower than that of a rapid flashing light. The left warning light 321 and the right warning light 322 can switch to a state where all or some of the LEDs are constantly lit to indicate that charging is complete.

[0152] In some embodiments, the LEDs of the left warning light 321 and the right warning light 322 gradually dim to indicate that the entire device is off. That is, when the left warning light 321 and the right warning light 322 are turned off, the lights gradually dim.

[0153] In some embodiments, a rear lighting assembly may also be included, disposed on both sides of the cushion 91. In some embodiments, the left warning light 321 and the right warning light 322 may be placed at any position on the left and right sides of the main body 10.

[0154] In some embodiments, there is one battery compartment 22, and multiple battery packs 21 are disposed within one battery compartment 22. In some embodiments, the number of battery compartments 22 is the same as the number of battery packs 21, and each battery pack 21 is disposed within a corresponding battery compartment 22. Optionally, there are multiple battery compartments 22 and multiple battery packs 21, and the number of battery packs 21 disposed within at least one of the multiple battery compartments 22 is greater than or equal to two. In some embodiments, the battery compartment 22 is provided with an input terminal configured to transmit electrical signals or communication signals. In some embodiments, the battery compartment 22 is further provided with a locking structure configured to lock the battery packs 21 disposed therein within the battery compartment 22, preventing poor contact between the battery packs 21 and the battery compartment 22, thereby affecting the normal operation of the vehicle.

[0155] In some embodiments, a socket is provided inside the battery compartment 22, and the battery pack 21 includes a plug that mates with the socket. When the battery pack 21 is placed inside the battery compartment 22, the plug is inserted into the socket to establish an electrical connection between the battery pack 21 and the battery compartment 22. In some embodiments, the surface of the battery compartment 22 is provided with multiple through holes. This reduces the weight of the battery compartment 22 while maintaining its strength, thereby reducing the overall weight of the device, and also enhances the heat dissipation efficiency of the battery pack 21.

[0156] In some embodiments, the battery compartment 22 has a body 221 with an opening for battery entry and exit, and a cover 222 may optionally cover the opening of the body 221. At least one of the body 221 and the cover 222 is provided with a first latch, which is operated to secure the cover 222 to the body 221. Exemplarily, the cover 222 can be completely separated from the body 221.

[0157] In some embodiments, at least one of the compartment body 221 and the compartment cover 222 is provided with a first latch, which is operated to secure the compartment cover 222 to the compartment body 221. The compartment cover 222 and the compartment body 221 are slidably connected.

[0158] like Figure 1As shown, in some embodiments, the standing lawnmower 100 is equipped with a lawnmower charging interface 773, using a charging gun to charge the battery pack 21. The relevant lawnmower charging interface 773 is typically horizontally positioned. Due to the height limitation of the lawnmower, it is inconvenient for operators to apply force when horizontally inserting or removing the charging gun, making insertion and removal difficult. In one embodiment of this application, the lawnmower has a charging interface 773 at its rear end, with the charging interface 773 at an angle of 60-75 degrees to the horizontal plane. The charging interface 773 is tilted upwards, making it easier for operators to apply force when inserting or removing the charging gun. In one embodiment, the charging interface 773 is provided with a flip-up charging port cover 774. The charging port cover opens during charging and automatically closes after charging is complete, reducing the amount of rainwater, debris, etc., falling into the charging interface 773 and reducing the incidence of malfunctions. It should be noted that the method of automatically closing the charging port cover can be selected from existing technologies based on actual conditions, and this application does not impose any restrictions on this.

[0159] The foregoing has shown and described the basic principles, main features, and advantages of this application. Those skilled in the art should understand that the above embodiments do not limit this application in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of this application.
