[0063] Continuing to refer to Figure 1 The main body 10 comprises a frame 11, a cutting assembly 80, a walking assembly 40 and a control assembly 70. The frame 11 is used to mount the cutting assembly 80, the walking assembly 40, the control mechanism 50 and the support mechanism 90.

[0064] As shown in Figure 4 The cutting assembly 80 comprises a mowing element for mowing and a mowing motor 82 for driving the mowing element. In the present 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 replaced by a mowing motor, but this does not limit the present application.

[0065] In some embodiments, the cutting assembly 80 comprises a plurality of mowing blades 81 and a mowing motor 82 for driving the mowing blades 81, i.e., the mowing motor 82 is provided with a plurality of mowing motors. In some embodiments, the cutting assembly 80 comprises a plurality of mowing blades 81 and a mowing motor 82 for driving the mowing blades 81, wherein the mowing motor 82 is provided with one or the number of mowing motors 82 is less than the number of mowing blades 81, i.e., one mowing motor 82 can drive a plurality of mowing blades 81.

[0066] As shown in Figure 3As shown, the walking assembly 40 supports the main body 10 and is configured to drive the standing-type mower 100 to walk. The walking assembly 40 includes walking wheels 411, 412 and walking motors 42. In the present embodiment, the walking assembly 40 includes at least two walking wheels, and the walking assembly 40 includes 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 is 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 motors 42 drive the rear walking wheel 411 or the front walking wheel 412 to rotate, so as to realize the walking function of the standing-type mower 100. Optionally, the number of the walking motors 42 can be one, two, three or four. In the present embodiment, the number of the walking motors 42 is at least two, and exemplarily, the number of the walking motors 42 is two, and the two walking motors 42 respectively drive the left rear walking wheel 411L and the right rear walking wheel 411R. Exemplarily, the left rear walking wheel 411L and the right rear walking wheel 411R are the driving wheels of the standing-type mower. Optionally, the front walking wheel 412 is provided as a universal wheel, so that the standing-type mower 100 can turn in other directions deviating from the front-rear direction. For convenience of reference, the walking motor 42 driving the left rear walking wheel 411L is set as a first walking motor 42L, and the walking motor 42 driving the right rear walking wheel 411R is set as a second walking motor 42R. In some embodiments, the walking motor 42 can be a hub motor or a wheel-side motor.

[0067] In the embodiment, the power supply 20 is configured to supply power to at least the walking assembly 40 to output a torque to drive the standing mower to walk, wherein a ratio of a maximum output torque of a single driving wheel (e.g., the left rear walking wheel 411L or the right rear walking wheel 411R) to an overall empty weight of the standing mower 100 is greater than or equal to 1.2 N·m / kg. In the embodiment, the first walking motor 42L drives the left rear walking wheel 411L, and the second walking motor 42R drives the right rear walking wheel 411R. It can be understood that the single driving wheel includes one of the left rear walking wheel 411L or the right rear walking wheel 411R. For the convenience of reference, the single driving wheel is taken as the left rear walking wheel 411L in the following, and the single driving wheel is 411L. In some embodiments, the ratio of the maximum output torque of the single driving wheel 411L to the overall empty weight of the standing mower 100 is greater than or equal to 1.1 N·m / kg. In some embodiments, the ratio of the maximum output torque of the single driving wheel 411L to the overall empty weight of the standing mower 100 is greater than or equal to 1.0 N·m / kg. In some embodiments, the ratio of the maximum output torque of the single driving wheel 411L to the overall empty weight of the standing mower 100 is greater than or equal to 1.3 N·m / kg. In some embodiments, the ratio of the maximum output torque of the single driving wheel 411L to the overall empty weight of the standing mower 100 is greater than or equal to 1.4 N·m / kg. In the embodiment, the ratio of the maximum output power of the single driving wheel 411L to the overall empty weight of the standing mower 100 is greater than or equal to 8.7 W / Kg. In some embodiments, the ratio of the maximum output power of the single driving wheel 411L to the overall empty weight of the standing mower 100 is greater than or equal to 8.6 W / Kg. In some embodiments, the ratio of the maximum output power of the single driving wheel 411L to the overall empty weight of the standing mower 100 is greater than or equal to 8.5 W / Kg. In some embodiments, the ratio of the maximum output power of the single driving wheel 411L to the overall empty weight of the standing mower 100 is greater than or equal to 8.8 W / Kg. In some embodiments, the ratio of the maximum output power of the single driving wheel 411L to the overall empty weight of the standing mower 100 is greater than or equal to 8.9 W / Kg. In some embodiments, the ratio of the maximum output power of the single driving wheel 411L to the overall empty weight of the standing mower 100 is greater than or equal to 9.0 W / Kg. It needs to be explained that the overall empty weight of the standing mower 100 is defined as the overall weight of the standing mower 100 when all the battery packs 21 accommodated in the battery compartment 22 of the standing mower 100 are installed and no user is loaded.

[0068] The standing mower 100 as an outdoor walking device, when performing outdoor work, will perform mowing work under working conditions such as slopes. When working on a slope, the walking assembly 40 of the standing mower 100 needs to provide sufficient traction to enable the standing mower 100 to overcome the gravity generated by its own weight and stabilize the uphill. At the same time, the walking assembly 40 also needs to ensure the stability of the standing mower 100 to avoid skidding and loss of control. In the embodiment, by defining the ratio of the maximum output torque of the single drive wheel 411L of the walking assembly 40 to the overall empty weight of the standing mower 100, the maximum output torque of the drive wheel that each unit weight of the standing mower 100 can receive is defined. The greater the ratio of the maximum output torque of the single drive wheel 411L to the overall empty weight of the standing mower 100, the more the maximum output torque of the drive wheel that each unit weight can receive, which in turn can indicate that the driving force of the walking motor 42 of the standing mower 100 is strong, and the weight of the standing mower 100 is more reasonable. In the embodiment, by also defining the ratio of the maximum output power of the single drive wheel 411L of the walking assembly 40 to the overall empty weight of the standing mower 100, the maximum output power of the drive wheel that each unit weight of the standing mower 100 can receive is defined. The greater the ratio of the maximum output torque of the single drive wheel 411L to the overall empty weight of the standing mower 100, the more the maximum output power of the drive wheel that each unit weight can receive, which in turn can indicate that the driving force of the walking motor of the standing mower 100 is strong, and the weight of the standing mower 100 is more reasonable.

[0069] In the 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), and the ratio of the rated output power of the walking assembly 40 to the overall empty weight 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 overall empty weight 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 overall empty weight is greater than or equal to 7.2 W / Kg. In the embodiment, by defining the ratio of the rated output power of the walking assembly 40 to the overall empty weight of the standing mower 100, the standing mower 100 can be understood as the power-to-weight ratio of the standing mower 100. The greater the power-to-weight ratio, the more the driving force of the drive wheel (411L, 411R) that each unit weight of the standing mower 100 can receive, which in turn can indicate that the driving force of the walking motor of the standing mower 100 is strong, and the weight of the standing mower 100 is more reasonable. It needs to be explained that the overall empty weight of the standing mower 100 is defined as: when all the battery packs 21 that can be accommodated in the battery compartment 22 of the standing mower 100 are installed and there is no user, the overall weight of the standing mower 100.

[0070] As shown in Figures 3 to 5 , the left front walking wheel 412L and the right front walking wheel 412R rotate around the front axis 403, and the left rear walking wheel 411L and the right rear walking wheel 411R rotate around the rear axis 402. It needs to be explained that the front axis 403 is the connecting line of the rotation axis of the left front walking wheel 412L and the rotation axis of the right front walking wheel 412R, and the front axis 403 is not necessarily the center line of the physical axis. As shown in Figure 5 , the overall vehicle wheelbase L is the distance between the front axis 403 and the rear axis 402. Under the condition of empty load of the whole machine, the ratio of the distance L1 between the center of gravity M of the standing type mower 100 and the rear axis 402 to the overall vehicle wheelbase L is greater than or equal to 0.2 and less than or equal to 0.35. Under the condition of empty load of the whole machine, the ratio of the distance L1 between the center of gravity M of the standing type mower 100 and the rear axis 402 to the overall vehicle wheelbase L is greater than or equal to 0.2 and less than or equal to 0.3. Under the condition of empty load of the whole machine, the ratio of the distance L1 between the center of gravity M of the standing type mower 100 and the rear axis 402 to the overall vehicle wheelbase L is greater than or equal to 0.25 and less than or equal to 0.35. The reasonable position of the center of gravity makes the standing type mower have better slope driving ability.

[0071] The walking assembly 40 further comprises a transmission assembly 45 configured to transmit the driving force of the walking motor 42 to the driving 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 driving wheels. In the present embodiment, the walking motor 42 comprises an output shaft extending along a first axis 401. The left rear walking wheel 411L and the right rear walking wheel 411R rotate around the rear axis 402, wherein the first axis 401 is parallel to but not coincident with the rear axis 402. In some embodiments, the first axis 401 is coincident with the rear axis 402. In the present embodiment, the transmission assembly 45 is configured as a speed reduction mechanism, for example, a gear transmission assembly 45 with speed reduction and torque increase, so that the output torque of the walking motor is the output torque of the driving 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 driving wheels.

[0072] As shown in Figure 1 and Figure 6As shown, the support mechanism 90 includes a standing platform 60 having a standing surface configured to support an operator. The standing platform 60 is disposed at a rear portion of the frame 11, connected to the frame 11, and located between the two rear walking wheels 411. A user stands on the standing platform 60 of the support mechanism 90, and the standing mower 100 is in a manned state when the user operates the standing mower 100 to work. When the standing mower 100 is in the manned state, the weight distributed by the front walking wheels 412 accounts for 20% to 30% of the total weight of the standing mower 100. In some embodiments, when the standing mower 100 is in the manned state, the weight distributed by the front walking wheels 412 accounts for 24% to 27% of the total weight of the standing mower 100. Since the weight of the user affects the total mass of the standing mower 100 in the manned state, the weight of the user is uniformly defined as 90 kg, and it can be understood that the total mass of the standing mower 100 in the manned state is the total weight of the standing mower 100 in the empty state plus 90 kg. When the standing mower 100 is switched from the empty state to the manned state, since the weight of the user is mainly added near the rear walking wheels 411, the position of the center of gravity of the standing mower 100 changes, as shown in FIG. 2B. Figure 6 As shown, in the manned state, the ratio of the distance L1' between the center of gravity M' of the standing mower 100 and the rear axis 402 to the wheelbase of the standing mower 100 is greater than or equal to 0.2 and less than or equal to 0.3.

[0073] In the present embodiment, the output power and the output torque of the driving wheels 411L, 412L of the standing mower 100 are reasonably set, the relationship between the output torque, the output power, and the empty mass of the related products is provided, the relationship between the center of gravity and the rear walking wheels 411 providing driving force is reasonably set, and the driving working ability of the standing mower 100 on a slope is ensured. The standing mower 100 provided in the present embodiment has a straight driving ability of 50 meters in the slope width direction on a slope with an inclination angle of not more than 20°, with a deviation of not more than 3 meters.

[0074] In the present embodiment, the rear walking wheels 411 include a left rear walking wheel 411L and a right rear walking wheel 411R. The left rear walking wheel 411L and the right rear walking wheel 411R are respectively configured as a size of 23x10.5-12. The output torque of a single driving wheel 411L is greater than or equal to 360 N·m. In some embodiments, the output torque of a single driving wheel 411L is greater than or equal to 370 N·m. In some embodiments, the output torque of a single driving wheel 411L is greater than or equal to 380 N·m.

[0075] Continuing with reference to Figure 1 and Figures 7 to 14As shown, the standing platform 60 is exemplarily a footboard 61 arranged at the rear of the frame 11, connected with the frame 11 and located between the two rear traveling wheels 411. A damper 62 is arranged between the footboard 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 damping value of the damper 62 arranged between the footboard 61 and the frame 11 is greater than or equal to 1000 N·s / m. In some embodiments, the damping value of the damper 62 arranged between the footboard 61 and the frame 11 is greater than or equal to 1500 N·s / m. In some embodiments, the damping value of the damper 62 arranged between the footboard 61 and the frame 11 is greater than or equal to 2000 N·s / m. In some embodiments, the damping value of the damper 62 arranged between the footboard 61 and the frame 11 is greater than or equal to 2500 N·s / m. In some embodiments, the damping value of the damper 62 arranged between the footboard 61 and the frame 11 is greater than or equal to 3000 N·s / m. In some embodiments, the damping value of the damper 62 arranged between the footboard 61 and the frame 11 is greater than or equal to 3500 N·s / m. In some embodiments, the damping value of the damper 62 arranged between the footboard 61 and the frame 11 is greater than or equal to 4000 N·s / m. The damper 62 connects the footboard 61 and the frame 11. Unlike outdoor working machines with seats, the user of the standing-type mower 100 needs to stand on the footboard 61 to operate the machine, and the comfort of the support of the footboard 61 to the user's feet is required during long-time standing. When the standing-type mower 100 travels on a bumpy road section, the footboard 61 will vibrate with the vibration frequency and amplitude of the whole vehicle, which will greatly impact the user, affecting the user's operation and observation, and also posing a safety hazard to the user. In this embodiment, the damper 62 is used to connect the footboard 61 and the frame 11, and the resistance provided by the damper 62 is used to reduce the vibration of the footboard 61 with the frame 11, and the damper 62 provides a damping value greater than or equal to 500 N·s / m to provide better vibration attenuation. If the damping value is too small, the damping effect cannot be achieved, and if the damping value is too large, the damping of the footboard 61 will be too hard. At the same time, after the damping value of the damper 62 and the overall stress of the footboard 61 reach a balance, the degree of vibration attenuation will gradually decrease, and even if the damping value continues to increase, the damping effect may actually decrease.

[0076] The support plate 615 is arranged below the footboard 61, and the elastic component 63 is arranged between the footboard 61 and the support plate 615. In some embodiments, the standing platform 60 includes at least one set of elastic components 63, and the elastic components 63 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 are themselves symmetric about the axis of the damper 62, that is, the central axis of the elastic components 63 coincides with the axis of the damper 63. For example, when the standing platform 60 includes two or more sets of elastic components 63, the two or more sets of elastic components 63 are symmetrically distributed about the axis of the damper 62. In some embodiments, the standing platform 60 includes elastic components 63, and the elastic components 63 are arranged substantially centrally relative to the footboard 61. For example, the standing platform 60 includes one set of elastic components 63, and the elastic components 63 are arranged on the axis of the footboard 61. In this embodiment, the damper 62 and the elastic component 63 are connected to the front side and the rear side of the footboard 61, respectively, in the front-rear direction. In some embodiments, the damper 62 and the elastic component 63 are arranged in the front-rear direction. In this embodiment, the damper 62 is used to provide better vibration damping in the upward and downward directions, and the elastic component 63 arranged below the footboard 61 is used to balance the weight of the human body, thereby achieving better damping effect. In this embodiment, the elastic component 63 includes a first elastic component 63a arranged on the left side of the damper 62 and a second elastic component 63b arranged on the right side of the damper 62, and the first elastic component 63a and the second elastic component 63b each adopt a compression elastic member, such as a compression spring.

[0077] As shown in Figure 9 , the footboard 61 is rotatably connected to the frame 11 by a first rotating shaft 618, and the center line of the first rotating shaft 618 is a third axis 601, wherein the third axis 601 and the rear axis 402 of the drive wheel are arranged in parallel with each other. When a user stands on the footboard 61 of the standing-type mower 100, the footboard 61 assembly is in a static equilibrium state, and in this state, the load is the weight G of the user. In this embodiment, as defined above, the weight of the user is 90 kg, and in the static equilibrium state:

[0078] J·a = G·S G -F c ·l + F k ·S k

[0079] wherein J is the moment of inertia of the footboard 61, a is the angular acceleration of the footboard 61, S G is the vertical distance from the center of gravity of the user standing to the third axis 601, F c is the damping force provided by the damper 62, and l is the force arm of the damper 62; F k is the elastic force provided by the elastic component 63, and S kThe elastic force arm. Under the above static balance, the elastic component 63 mainly plays a supporting role, balancing the body weight, secondly, the elastic component 63 provides partial resistance to play a vibration isolation role. While the damper 62 plays a damping role, mainly used to absorb the vibration energy of the foot pedal 61.

[0080] The resistance provided by the damper 62 is adjusted by adjusting the force arm of the damper 62. In the unloaded state, that is, when the user does not stand on the foot pedal 61, according to the formula:

[0081] l = s sin a

[0082] As shown in Figure 10 , wherein l is the force arm of the damper 62, s is the vertical distance from the connecting fulcrum of the first end 621 of the damper 62 to the third axis 601 to the rack 11, and a is the inclination angle of the damper 62.

[0083] In this embodiment, s is taken as a fixed value, that is, the vertical distance from the connecting fulcrum of the first end 621 of the damper 62 to the third axis 601 to the rack 11 is not changed, and the force arm of the damper 62 is adjusted by adjusting the inclination angle a of the damper 62. The rack 11 includes a cross beam 113, and the foot pedal 61 includes a connecting piece 611, the first end 621 of the damper 62 is connected to the cross beam 113, and the second end 622 is connected to the connecting piece 611, and the connecting piece 611 is detachably connected to the damper 62. As shown in Figure 12 , the connecting piece 611 includes a plurality of connecting points 614, and the second end 622 of the damper 62 has different inclination angles a when connected to any one of the connecting points 614. By changing the connection position of the damper 62, the force arm of the damper 62 is adjusted. For example, the second end 622 of the damper 62 is connected to the connecting point 614 by detachable fasteners, such as bolts and nuts. For example, the connecting piece 611 includes two plate structures, including a first connecting plate 612 and a second connecting plate 613, and the first connecting plate 612 and the second connecting plate 613 are respectively arranged on the left and right sides of the damper 62. Taking the first connecting plate 612 as an example, a plurality of connecting points 614 are arranged on the first connecting plate 612 in the transverse and longitudinal directions. The opening direction of the connecting point 614 extends in the left and right directions.

[0084] As shown in Figure 13 , in this embodiment, the connecting piece 611 is arranged in the foot pedal 61, that is, the orthographic projection of the connecting piece 611 is located in the orthographic projection of the foot pedal 61 in the up-down direction. In some embodiments, as shown in 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.

[0085] 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.

[0086] 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.

[0087] like Figures 9 to 14As shown, taking the first elastic component 63a as an example, the first elastic component 63a includes a first elastic member 631 and a second elastic member 632, which are distributed along the front-rear direction of the standing-type lawn mower 100. For example, the first elastic member 631 and the second elastic member 632 are staggered and distributed front and back. Optionally, the first elastic member 631 and the second elastic member 632 include at least two specifications of compression springs. Two compression springs of different specifications are used. Optionally, the first elastic member 631 and the second elastic member 632 include two specifications of compression springs that are the same. In the unloaded state, the first elastic member 631 and the second elastic member 632 are respectively connected to the foot pedal, and the first elastic member 631 and the second elastic member 632 have different heights. So that when the load is less than a preset value, any one of the first elastic member 631 or the second elastic member 632 provides a support force to support the user, to adapt 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's weight is heavy, 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, and according to the change of the user's weight and the load, the user can adjust the preset value of the load. For example, the first elastic member 631 and the second elastic member 632 provide different stiffness, the first elastic member 631 is arranged in front of the second elastic member 632, and the stiffness of the first elastic member 631 is greater than that of the second elastic member 632. For example, the first elastic member 631 and the second elastic member 632 provide the same stiffness, and the unloaded heights of the first elastic member 631 and the second elastic member 632 are different.

[0088] Since the second elastic member 632 component is symmetrically arranged with the first elastic member 631 component, the structure is basically the same, and the structure of the second elastic member 632 component will not be described one by one.

[0089] In this embodiment, the standing platform 60 uses a combination of the damper 62 and the elastic component 63 arranged in a split manner for damping. The elastic component 63 mainly serves as a support to balance the body weight, and the damper 62 serves as a damping function to absorb the vibration energy of the foot pedal 61. The elastic component 63 is symmetrically arranged on both sides of the damper 62 to provide independent support for the user's feet. When the user's feet apply different forces, the elastic component 63 can also provide independent support. The elastic component 63 is configured as a multi-spring structure to adapt to different weights, and the damper 62 is set to an appropriate damping value. The support force provided by the elastic component 63 and the resistance provided by the damper 62 cooperate with each other to realize a standing-type lawn mower 100 that is suitable for all-weather damping support for various weights.

[0090] The standing platform 60 further comprises a first connecting member 616 connecting the frame 11 and the foot plate 61, and a second connecting member 617 connecting the support plate 615 and the frame 11. One end of the first connecting member 616 is connected with the cross beam 113 of the frame 11, and the other end is rotatably connected with the foot plate 61 through a first rotating shaft 618. In some embodiments, the first connecting member 616 is formed with the frame 11, and the foot plate 61 is rotatably connected with the first connecting member 616 through the first rotating shaft 618. In the present embodiment, the first connecting member 616 extends in a direction perpendicular to the third axis 601, for example, in a vertical direction. The first connecting member 616 is symmetrically arranged with the center line of the damper 62. The second connecting member 617 is arranged on the left and right sides of the foot plate 61 respectively, and extends in a direction perpendicular to the third axis 601, for example, in a vertical direction.

[0091] As another embodiment of the present application, the standing platform 60A is provided with an adjusting assembly 80 for adjusting the pre-pressing force of the damper 62A to match operators of different weights, as shown in Figures 15 to 17 The standing platform 60A is provided with an adjusting assembly 80 for adjusting the pre-pressing force of the damper 62A to match operators of different weights, as shown in Figures 7 to 14 The same as the parts in the standing platform 60, Figures 15 to 17 The same as the parts in the standing platform 60, Figures 7 to 14 The same as the parts in the standing platform 60,

[0092] When the operator is not standing on the foot plate 61, i.e., the foot plate 61 does not provide support force, the foot plate 61 is in the first position; when the operator stands on the foot plate 61, the foot plate 61 rotates about the third axis 601 to the second position (as shown in Figure 15 The damper 62A provides resistance to the movement or movement tendency of the foot plate 61. During the operation of the standing mower, the standing mower swings to swing the operator. Since the foot plate 61 is connected in a floating manner, the damper 62A can absorb part of the swing amount of the foot plate 61 to achieve the purpose of shock absorption.

[0093] The damper 62A is configured with a pre-pressing force, which is the resistance provided by the damper 62A to the foot plate 61 when the foot plate 61 does not support the operator, i.e., the foot plate 61 is in the first position. The pre-pressing force affects the swing amplitude of the foot plate 61. Too large pre-pressing force will cause the foot plate 61 to have the risk of touching the limit, and too small pre-pressing force will reduce the shock absorption effect. Therefore, to achieve the optimal shock absorption effect, the pre-pressing force provided by the damper 62A to the foot plate 61 needs to meet the preset condition. The size of the pre-pressing force is related to the weight of the operator, and the support force of the foot plate to the operator is related to the weight of the operator. For operators of different weights, corresponding pre-pressing force needs to be matched to achieve optimal shock absorption effect.

[0094] The adjusting assembly 80 is operable to adjust the pre-pressing force of the damper 62A, so that when the footrest 61 supports an operator, the resistance provided by the damper 62A to the footrest 61 remains substantially unchanged when the supporting force of the footrest 61 to the operator changes, so as to adapt to operators with different weights, and the damper 62A can provide the footrest 61 with a resistance meeting a preset condition for operators with different weights. By setting the adjusting assembly 80, the pre-pressing force of the damper 62A can be adjusted to adapt to operators with different weights, so that the damper 62A can achieve a better damping effect for operators with different weights. The adjusting assembly 80 adjusts the relative position of the footrest 61 and the frame, so that when the footrest 61 is in the first position, the damper 62A provides the footrest 61 with a resistance.

[0095] The adjusting assembly 80 includes an elastic element 82 and a setting part 81. One end of the elastic element 82 is connected to the footrest 61, and the other end is connected to the frame 11. The elastic element 82 applies an upward force to the footrest 61. The setting part 81 can set the combined position of the elastic element 82 on the frame 11, thereby setting the size of the force applied by the elastic element 82 to the footrest 61. The elastic element 82 can have multiple combined positions with the frame 11 to adapt to operators with different weights. When operators with different weights stand on the footrest 61, the size of the force applied by the elastic element 82 to the footrest 61 is set by combining the elastic element 82 with different combined positions of the frame 11, so as to compensate for the pre-pressing force of the damper 62A, and operators with different weights can achieve approximately the same suspension experience.

[0096] The frame 11 is provided with a plurality of combined parts 83. The plurality of combined parts 83 are spaced apart along the height direction of the frame 11. The setting part 81 is selectively combined with the combined parts 83. The plurality of combined parts 83 can include two or more positions, for example Figure 15The five positions. Assuming the maximum load of the foot pedal 61 is 100 kg, when an operator with a body weight of 100 kg stands on the foot pedal 61, the elastic element 82 is combined with the lowermost combination part 83, at which time the damping effect of the suspension assembly 70 is optimal; when an operator with a body weight less than 100 kg stands on the foot pedal 61, the combination position of the elastic element 82 needs to be moved upward to compensate for the pre-pressing force of the damping member 62A, so that the damping member 62A is subjected to a force equivalent to that when an operator with a body weight of 100 kg stands on the foot pedal 61. Exemplarily, when an operator with a body weight of 80-100 kg stands on the foot pedal 61, the combination position of the elastic element 82 can be moved upward by one position from the lowermost position; when an operator with a body weight of 60-80 kg stands on the foot pedal 61, the combination position of the elastic element 82 can be moved upward by two positions from the lowermost position; when an operator with a body weight of 40-60 kg stands on the foot pedal 61, the combination position of the elastic element 82 can be moved upward by three positions from the lowermost position; and when an operator with a body weight of 40 kg or less stands on the foot pedal 61, the combination position of the elastic element 82 can be moved upward by four positions from the lowermost position, i.e., to the uppermost position.

[0097] In some embodiments, the combination part 83 can be a plug-in part, such as a plug-in hole, and the setting part 81 can be a plug-in rod, which is plugged into the plug-in part. In some embodiments, the combination part 83 can be a hooking part, such as a hooking hole, and the setting part 81 can be a hook, which is hooked onto the hooking part. In some embodiments, the combination part 83 can be a clamping part, such as a clamping groove, and the setting part 81 can be a clamping buckle, which is clamped onto the clamping part. The above are only exemplary descriptions, but are not limited thereto.

[0098] In some embodiments, the limiting part is manually adjusted, i.e., the setting part 81 is manually combined with the corresponding combination part 83. Since the user of a standing-type mower is relatively fixed, the manually adjusted scheme can meet the demand. In some embodiments, the limiting part is automatically adjusted, for example, an electric motor and a rack can be used to drive the setting part 81 to be combined with the combination part 83.

[0099] In some embodiments, the adjusting assembly 80 is provided with two adjusting assemblies 80, which are symmetrically distributed relative to the damping member 62A. The two adjusting assemblies 80 can be adjusted respectively, and the adjusting amount of the two adjusting assemblies 80 can be the same or different. The two adjusting assemblies 80 can also be synchronously adjusted through a linkage mechanism. In some embodiments, the number of adjusting assemblies 80 is more than two.

[0100] 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.

[0101] 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.

[0102] In the embodiment, the cushion 91 is detachably connected with the main body 10. The cushion 91 can be detached from the main body 10 when the lawn mower 1 is transported or needs to be cleaned. The cushion 91 is provided with a limiting structure matched with the frame 11. When the cushion 91 needs to be fixed on the main body 10, the limiting structure locks the cushion 91 with the frame 11. When the cushion 91 needs to be detached, the limiting of the limiting structure is released through an unlocking operation, and the cushion 91 can be separated from the frame 11. Optionally, the limiting structure includes a movable buckle structure, or a threaded structure, or a hook hole structure. The unlocking operation drives the limiting of the limiting structure to be released, including one-key unlocking, for example, one press or one dial of the limiting structure is switched from the limiting state to the limiting release state, and also including linear release unlocking, for example, the limiting state of the limiting structure is linearly changed to switch to the release state with each operation. At the same time, the above unlocking operations do not need to be assisted by tools or special or professional tools, and the installation and detachment of the cushion 91 are achieved by hand.

[0103] As shown in Figure 20 , the control assembly 70 controls at least the running state of the walking motor 42 and the mowing motor 82. The control assembly 70 includes a driving circuit 73 and a controller 72. Exemplarily, the controller 72 adopts a dedicated control chip, for example, a single-chip microcomputer or a microcontroller unit (MCU). The controller 72 specifically controls the on or off state of the switching element in the driving circuit 73 through the control chip. Exemplarily, the driving circuit 73 includes a power tube (for example, a metal-oxide-semiconductor field-effect transistor, MOSFET). Exemplarily, the controller 72 is arranged on a control circuit board 71, and the control circuit board 71 includes a printed circuit board (PCB) and a flexible printed circuit (FPC).

[0104] As shown in Figure 1 and Figure 18As shown, in the embodiment, the control assembly 70 further comprises an electric control box 74, which is provided with a receiving portion configured to receive the control circuit board 71. The electric control box 74 is arranged between the power supply 20 and the standing platform 60, for example, above the standing platform 60, at the rear side of the battery compartment 22. For example, the electric control box 74 is arranged in front of the backrest 91. When the control assembly 70 needs to be checked or maintained, the control assembly 70 can be maintained by removing the backrest 91, thereby improving the convenience of maintenance. The control circuit board 71 in the electric control box 74 is provided with a plurality of control chips, capacitors and other electrical elements. During the operation of the standing mower 100, a large amount of heat is generated, which may, on the one hand, damage the electrical elements, and on the other hand, cause the controller 72 to enter an overheating protection program, thereby affecting the use of the product.

[0105] To ensure the heat dissipation of the control assembly 70, the main body 10 further comprises a heat dissipation assembly 741, which comprises a fan 742, a wind pump 744 and a ventilation pipeline 745. The fan 742 and the wind pump 744 are connected by a pipeline 747. The outlet of the wind pump 744 is in communication with the inlet of the ventilation pipeline 745. The outlet of the ventilation pipeline 745 faces the electric control box 74, thereby forming a heat dissipation air path from the fan 742 to the electric control box 74. In the embodiment, the fan 742 and the wind pump 744 are arranged on the left and right sides of the power supply 20, respectively. For example, a water vapor separator 746 is arranged upstream of the fan 742. The outlet of the water vapor separator 746 is connected to the fan 742. In the embodiment, the fan 742 is arranged in the reversing portion. The electronic components in the electric control box 74 are ensured to dissipate heat.

[0106] As shown, Figures 18 to 22 The central control mechanism 50 comprises an operation table 51 configured to be operated by a user to control the operation of the standing mower 100. The operation table 51 is arranged above the footrest. The operation table 51 is provided with an operation portion 52, which comprises a left driving rod 52L and a right driving rod 52R. The operation portion 52 is configured to be held by an operator to control at least the walking direction and the walking speed of the standing mower 100. The walking direction of the standing mower 100 includes forward movement, backward movement, left turning and right turning. In some embodiments, the controller 72 outputs control instructions based on the actions on the driving rods. The control instructions include forward / backward movement instructions, turning instructions and zero turning instructions.

[0107] In some embodiments, the operation part 52 includes a left driving rod 52L and a right driving rod 52R, which are configured to be held by the operator with both hands to control at least the walking direction and the walking speed of the standing mower 100. The left driving rod 52L and the right driving rod 52R are movably connected to the operation table shell 511. To ensure that the left driving rod 52L and the right driving rod 52R have a moving space, the operation table shell 511 is provided with a track through hole 512 matching the movement track of the left driving rod 52L and the right driving rod 52R. To prevent foreign matter from entering the inside of the operation table 51 through the track through hole 512, a protection part 513 is added to the track through hole 512. For example, the protection part 513 is a protective net, a protective cover, or other structures. The left driving rod 52L and the right driving rod 52R are symmetrically arranged. For example, the right driving rod 52R is L-shaped, including a vertical part 522 and a horizontal part 521. The vertical part 522 is rotatably arranged on the operation table 51, and the horizontal part 521 intersects with the extension direction of the vertical part 522. The horizontal part 521 extends substantially horizontally, and the horizontal parts 521 of the left driving rod 52L and the right driving rod 52R extend towards each other. The operator can hold both hands on the two horizontal parts 521 to operate the left driving rod 52L and the right driving rod 52R. In some embodiments, the operator can control the standing mower 100 to move forward by simultaneously rotating the left driving rod 52L and the right driving rod 52R forward, and control the standing mower 100 to move backward by simultaneously rotating the left driving rod 52L and the right driving rod 52R backward. The operator can control the standing mower 100 to turn left by only rotating the left driving rod, and control the standing mower 100 to turn right by only rotating the right driving rod. In some embodiments, the operator can control the walking speed of the standing mower 100 by adjusting the rotation amplitude of the driving rod.

[0108] In some embodiments, the left driving rod 52L and the right driving rod 52R are also configured to be operated by the operator to have at least a first position opened to both sides and a second position closed to the middle. The controller 72 is configured to allow the current in the power supply 20 to flow to the walking motor 42 when at least a first signal that the left driving rod 52L and the right driving rod 52R are switched from the second position to the first position and a second signal that the left driving rod 52L and the right driving rod 52R are switched from the first position to the second position are detected in sequence. In this way, the purpose of safe start is achieved, and the problem of the standing mower 100 recklessly walking due to the operator accidentally touching the driving rod is avoided.

[0109] 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.

[0110] like Figures 19 to 21As shown, in the present embodiment, the operating platform 51 is movably connected with the frame 11. The operating platform 51 comprises an operating platform housing 511, and the operating part 52 and the display screen 53 are arranged on the operating platform housing 511. The operating platform comprises a first position and a second position, and the height of the upper edge of the operating platform 51 to the ground plane where the walking assembly 40 is located is different between the first position and the second position. When the operating platform is in the first position, the operating platform as a whole extends in the up-down direction for the user to use. When the operating platform is in the second position, the height of the upper edge of the operating platform to the ground plane where the walking assembly is located is reduced. The height H3 of the upper edge of the operating platform 51 to the ground plane where the walking assembly is located when the operating platform is in the second position is less than the height H4 of the upper edge of the operating platform 51 to the ground plane where the walking assembly is located when the operating platform is in the first position. For example, when the operating platform is in the first position, the operating platform is in a working state, and the user stands on the footboard 61 to control the walking assembly by operating the operating part 52. When the operating platform is in the second position, the operating platform is in a storage state, and the operating platform cannot be operated by the user to control the walking assembly. In the present embodiment, the operating part 52 protrudes from the operating platform housing, and therefore, in some examples, the height H4 of the upper edge of the operating part 52 to the ground plane where the walking assembly 40 is located in the up-down direction when the operating platform 51 is in the working state is greater than or equal to 1100 mm. In some examples, the height H4 of the upper edge of the operating part 52 to the ground plane where the walking assembly 40 is located in the up-down direction when the operating platform 51 is in the working state is greater than or equal to 1200 mm. In the present embodiment, the height H4 of the upper edge of the operating part 52 to the ground plane where the walking assembly 40 is located in the up-down direction when the operating platform 51 is in the working state is equal to 1220 mm. It can be understood that the overall height H4 of the standing-type lawn mower 100 when the operating platform 51 is in the working state is greater than or equal to 1100 mm. In the present embodiment, the overall height H4 of the standing-type lawn mower 100 when the operating platform 51 is in the working state is equal to 1220 mm.

[0111] In the present embodiment, the operating platform 51 is connected with the frame 11 through the operating platform rotation shaft 514, and the operating platform 51 rotates relative to the frame 11 about the rotation axis. For convenience of reference, the rotation axis of the operating platform rotation shaft 514 is the fourth axis 501. The operating platform 51 rotates relative to the frame 11 about the fourth axis 501. The fourth axis 501 is arranged in parallel with the rear axis 402 of the driving wheel. When the operating platform 51 switches between the first position and the second position, the operating platform 51 rotates about the fourth axis 501, and the operating part 52 and the display screen 53 rotate together with the operating platform housing 511. Figure 19 and Figure 20As shown, when the operating platform 51 is in the second position, i.e., in the storage state, the operating platform 51 is operated to rotate around the fourth axis 501 towards the footboard 61, and the operating part 52 is towards the footboard 61. For example, the operating platform rotating shaft 514 is arranged at the rear of the operating platform housing 511, so when the operating platform 51 is operated to the storage state, the operating platform 51 is flipped to the rear of the frame 11 as a whole, and the operating part 52 is flipped to be towards the footboard 61 at the same time, thereby reducing the overall height of the standing mower 100. When the operating platform 51 is in the storage state, the height H3 from the highest point of the standing mower 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 operating platform 51 is in the storage state, the height H3 from the highest point of the standing mower 100 to the ground plane where the walking assembly 40 is located is equal to 950 mm. Through the rotation of the operating platform 51, the overall height of the standing mower 100 is reduced by more than 20%, which is beneficial to the loading rate of the container during the transportation of the standing mower 100.

[0112] In some embodiments, the rotation angle of the operation platform 51 around the fourth axis 501 is greater than or equal to 90°, in some embodiments, the rotation angle of the operation platform 51 around the fourth axis 501 is greater than or equal to 100°, in some embodiments, the rotation angle of the operation platform 51 around the fourth axis 501 is greater than or equal to 110°, in some embodiments, the rotation angle of the operation platform 51 around the fourth axis 501 is greater than or equal to 120°, in some embodiments, the rotation angle of the operation platform 51 around the fourth axis 501 is greater than or equal to 130°, in some embodiments, the rotation angle of the operation platform 51 around the fourth axis 501 is greater than or equal to 140°, and in the present embodiment, the rotation angle of the operation platform 51 around the fourth axis 501 is equal to 150°. The operation platform housing 511 is positioned and connected with the rack 11 in the working state and the storage state. For example, a locking member 54 is arranged between the operation platform housing 511 and the rack 11. The locking member 54 is detachably connected with at least one of the operation platform housing 511 and the rack 11. When the operation platform 51 is switched between the working state and the storage state, the locking member 54 is detached from at least one of the operation platform housing 511 and the rack 11, so that the operation platform housing 511 and the rack 11 are operated to move relatively. When the operation platform 51 is in the working state or the storage state, the locking member 54 positions and connects the operation platform housing 511 and the rack 11, and the operation platform housing 511 and the rack 11 cannot move relatively. It is ensured that the operation platform housing 511 and the rack 11 are relatively fixed when the operation platform 51 is in the storage state, preventing the operation platform from shaking during transportation. For example, the locking member 54 includes a pin shaft 541, and the operation platform housing 511 and the rack 11 are correspondingly provided with positioning holes 542 capable of accommodating the pin shaft 541. The operation platform housing 511 and the rack 11 are respectively provided with positioning holes 542 corresponding to the working state and the storage state. In some embodiments, the operation platform housing 511 and the rack 11 are provided with a plurality of positioning holes 542, so that the operation platform housing 511 and the rack 11 can be positioned and connected at a plurality of angles.

[0113] In some embodiments, a power assisting member 543 is arranged between the operation platform 51 and the rack 11 to assist the user in turning over the operation platform 51. For example, the power assisting member 543 includes a hydraulic rod, a gas spring supporting rod, etc. The power assisting member 543 also serves as a buffer to prevent the operation platform 51 from colliding with the rack 11 during turning over.

[0114] For example, Figures 22 to 23The operation platform 51 further comprises a plurality of operation members 77, and the controller 72 is connected with the operation members 77 respectively. In the embodiment, the plurality of operation members 77 comprises an emergency stop switch 771, and the controller 72 is configured to send a stop signal to the walking motor 42 and the mowing motor 82 when the emergency stop switch 771 is triggered. In the embodiment, the storage module of the controller 72 at least comprises two different control methods of an automatic mode and a manual mode. When the controller 72 is switched to the manual mode, the controller 72 outputs a control instruction based on the action on the operation part 53 to control the running state of the walking motor 42, and the running speed of the mowing motor 82 is controlled through the speed regulation module. When the controller 72 is switched to the automatic mode, the controller 72 no longer outputs a control instruction in response to the operation of the operation part 53, and the controller 72 controls the speed of the walking motor 42 and the walking route of the walking assembly 40 based on the pre-set parameters. The pre-set parameters include but are not limited to the following setting forms: a plurality of different fixed parameters of the running mode are stored in the controller 72 at the factory, the user selects the mode but cannot modify the parameters, or the user can adjust the given parameters as needed, but the values of the parameters are a plurality of specified values, and the user cannot define the values at will, or the user adjusts the parameter values of the required parameter types as needed to meet the use requirements of the customer. It can be understood that in the manual mode, the user needs to give operation instructions at all times to make the standing-type mower 100 complete the work, and in the automatic mode, the user can only observe and does not need to give operation instructions at all times to control the running of the standing-type mower 100. However, if the standing-type mower 100 deviates from the specified abnormal running state due to external reasons or failure or abnormality of the vehicle itself in the automatic mode, the user needs to quickly and urgently stop the running and mowing of the standing-type mower 100 to ensure safety. The application sets the emergency stop switch 771, and when the abnormal state occurs, the user actively triggers the emergency stop switch 771, and the controller 72 sends a stop instruction to the walking motor 42 and the mowing motor 82, and the walking motor 42 and / or the mowing motor 82 that are running respond to the stop instruction to stop working quickly, and the walking motor 42 or the mowing motor 82 that are not working do not need to respond to the stop instruction, thereby ensuring the safety of the standing-type mower 100 and the user.

[0115] In the embodiment, when the emergency stop switch 771 is triggered, the controller 72 enters the manual mode, and the user takes over the running and driving of the standing-type mower 100. Therefore, the standing-type mower 100 is controlled by the user by default when it is started again after emergency stop, and is switched to the automatic mode according to the need after the user confirms the fault or abnormality.

[0116] In some embodiments, when the emergency stop switch 771 is connected between the traveling motor 42 and the mowing motor 82 and the battery pack 21, when the emergency stop switch 771 is triggered, the electrical connection between the traveling motor 42 and the mowing motor 82 and the battery pack 21 is disconnected, and the traveling motor 42 and the mowing motor 82 are powered off and stopped.

[0117] In some embodiments, when the emergency stop switch 771 is connected between the controller 72 and the traveling motor 42 and the mowing motor 82, and optionally when the emergency stop switch 771 is triggered, the controller 72 sends a rapid braking signal to the traveling motor 42 and the mowing motor 82, and the traveling motor 42 and the mowing motor 82 respond to the rapid braking signal to perform short-circuit braking and motor reverse torque braking.

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 be automatically reset after being operated and triggered.

[0119] In this embodiment, the plurality of operating members 77 includes a start switch 772, which is activated to power on the electric components of the standing lawn mower or start the operation. Optionally, the start switch 772 is a physical switch such as a button, a knob, a lever or a key. Optionally, the start switch 772 can be an electronic switch with electronic identification function, such as password identification, chip identification, NTC identification, and contact-type electronic switches for biometric identification such as face recognition and fingerprint recognition. Optionally, the start switch 772 is an electronic switch, and the trigger instruction of the electronic switch is sent to the start switch 772 through a non-contact signal transmission method such as IoT, Bluetooth and remote control.

Optionally, it includes the above three switches.

[0120] As shown in 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 located on the same control circuit board 71; in some embodiments, the ESP controller 751 and controller 72 are located 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.

[0121] 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.

[0122] 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.

[0123] In the embodiment, the controller 72 and the energy management controller 782 are both arranged in the electric 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 mowing motor 82, the first control module and the second control module can be integrated in one control chip or can be respectively arranged in multiple control chips. The controller 72 and the energy management controller 782 can be integrated on the same control circuit board 71 or can be respectively arranged on different control circuit boards 71, but the control circuit boards 71 are all arranged in the electric control box 74, which is integrated arrangement, convenient for maintenance, and saves space and shares the heat dissipation structure.

[0124] In some embodiments, a damping device 748 is arranged at the connection between the electric control box 74 and the power management board 781 and the rack 11, configured to reduce the vibration load of the connector and the internal components. Optionally, the damping device includes shock-absorbing rubber, silicone or other elastic damping components.

[0125] As shown in Figures 26 to 28 The main body part 10 further includes a height adjusting device 841 configured to adjust the distance between the cutting assembly 80 as a whole and the ground, and a locking device 842 configured to lock the distance between the cutting assembly 80 as a whole and the ground. In order to facilitate the worker standing on the mower to adjust the height of the cutting assembly 80, the mower is provided with an adjusting handle 843 extending outside the rack 11. The adjusting handle 843 is movably connected with the rack 11, the height of the adjusting handle 843 is greater than or equal to the height of the operating part 53, and the adjusting handle 843 is arranged on the right side of the main body part 10, so that the user standing on the standing platform 60 can still operate the adjusting handle 843 to drive the height adjusting device 841 to adjust the height of the cutting assembly 80, and can also operate the adjusting handle 843 to drive the locking device 842 to lock the distance. In some embodiments, the adjusting handle 843 is detachably connected with the rack 11, for example, the handle and the rack 11 have multiple mounting positions, different mounting positions make the handle have different mounting angles or mounting heights relative to the rack 11, adapt to the height and operation habit of the user. When the operating table 51 is in the storage state, the adjusting handle 843 is detached and stored to reduce the packaging space. In some embodiments, the adjusting handle is arranged in a telescopic or folding structure, when the operating table 51 is in the storage state, the adjusting handle 843 is folded or retracted to reduce the size, so as to reduce the packaging space.

[0126] 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.

[0127] In some embodiments, an active adjustment mechanism 833 is also included.

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.

[0128] 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.

[0132] 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 disposed on the left or right side of the front frame 111. 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.

[0133] 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.

[0134] 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.
