In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0069] In this application, the term "and / or" simply describes a relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can mean: A exists alone, A and B exist simultaneously, or B exists alone. Additionally, the character " / " in this application generally indicates that the related objects are in an "or" relationship.

[0070] In this application, the terms "connect," "combine," "couple," and "install" may 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 being connected to at least one intermediary, with the two parts or components being connected via the intermediary. Furthermore, "connect" and "couple" are not limited to physical or mechanical connections or couplings and may include electrical connections or couplings.

[0071] Those skilled in the art will understand that relative terms used in conjunction with quantities or conditions (e.g., "about," "approximately," "substantially," etc.) include the stated value and have the meaning dictated by the context (e.g., the term includes at least the degree of error associated with the measurement of the particular value, the tolerance associated with the particular value (e.g., manufacturing, assembly, use), etc.). Such terms should also be considered to disclose a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to plus or minus a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Of course, numerical values ​​that do not employ relative terms should also be disclosed as specific values ​​with tolerances. In addition, "substantially" may refer to plus or minus a certain number of degrees (e.g., 1 degree, 5 degrees, 10 degrees or more) based on the indicated angle when expressing a relative angular position relationship (e.g., substantially parallel, substantially perpendicular).

[0072] In this application, it will be understood by those skilled in the art that a function performed by a component may be performed by one component, multiple components, or multiple parts, or may be performed by one part. Similarly, a function performed by a part may be performed by one part, one component, or a combination of multiple parts.

[0073] In the present application, the terms "upper", "lower", "left", "right", "front", "back" and other directional words are described based on the orientation and positional relationship shown in the accompanying drawings, and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to the other element "upper" or "lower", but also be indirectly connected to the other element "upper" or "lower" through an intermediate element. It should also be understood that directional words such as upper side, lower side, left side, right side, front side, back side do not represent the positive orientation, but can also be understood as lateral orientation.

In some embodiments, the user can simultaneously rotate the drive levers 54 forward to control the stand-on lawn mower forward, rotate the drive levers 54 backward to control the stand-on lawn mower backward, rotate only the left drive lever 54 forward to control the stand-on lawn mower to turn left, and rotate only the right drive lever 54 forward to control the stand-on lawn mower to turn right. In some embodiments, the user can control the travel speed of the stand-on lawn mower by adjusting the rotation amplitude of the drive levers 54. In some embodiments, the control component can output control instructions based on the action on the drive rod 54, and the control instructions include forward / reverse instructions, turn instructions, and zero turn instructions. Referring to Figure 5a, the pair of drive rods 54 are also configured for user operation to have at least a first position a open to both sides and a second position b closed to the middle. The control component is configured to allow current in the power supply device 40 to flow to the first motor when at least a first signal indicating that the operating rod is switched from the second position to the first position and a second signal indicating that the operating rod is switched from the first position to the second position are detected in sequence. This arrangement is to achieve the purpose of safe startup and avoid the problem of the stand-on lawn mower moving rashly due to the user accidentally touching the drive rod 54.

[0082] In some embodiments, the operating console 51 is further provided with a user interface comprising a display screen 55 having a display plane 551. The projection of the drive rod 54 in the second position onto the first plane 101 at least partially overlaps with the projection of the display plane onto the first plane.

The drive rod 54 can rotate left and right about the first axis 501, thereby enabling the drive rod 54 to switch between the first position and the second position. In some embodiments, a U-shaped bracket 543 is provided at the lower end of the drive rod 54, and a portion of the first bracket 561 is inserted into the U-shaped bracket 543. The first rotating shaft is sequentially disposed through a side wall of the U-shaped frame 543, a first bracket 561, and the other side wall of the U-shaped frame 543, thereby achieving a stable connection between the drive rod 54 and the first bracket 561. The opening and closing structure 56 also includes a second bracket 562. The first bracket 561 and the second bracket 562 are rotatably connected via a second rotating shaft. The axis of the second rotating shaft is the second axis 502, which extends in the left-right direction of the stand-on lawn mower. The drive rod 54 can rotate back and forth about the second axis 502, thereby controlling the travel direction and speed of the stand-on lawn mower. Optionally, the opening and closing structure 56 also includes two elastic members 563. Both elastic members 563 are disposed in a compressed state between the first bracket 561 and the second bracket 562, and the two elastic members 563 are distributed on both sides of the second axis 502 along the front-to-back direction of the stand-on lawn mower. When the user operates the drive rod 54 to rotate back and forth, the elastic members 563 can release a certain amount of damping, making operation more convenient.

[0084] As shown in Figures 1 and 2, the support mechanism includes a standing platform 60 having a standing surface configured to support a user. The standing platform 60 is disposed at the rear portion of the frame 10, connected to the frame 10, and positioned between the two rear wheels 22. In some embodiments, the standing platform 60 is partially positioned between the two rear wheels 22, with the end of the standing platform 60 closest to the front wheels 21 positioned between the axis of the front and rear wheels 21, 22. This allows the user to stand on the standing platform 60, with their center of gravity centered on the axis of the rear wheels 22. When the stand-on lawn mower rotates, there is no rotation radius, no centrifugal force generated, and no risk of being thrown from the ground. Furthermore, as the standing platform 60 moves forward, the user's center of gravity also moves forward, making climbing slopes and navigating bumpy terrain safer and less prone to overturning.

[0085] The balancing device 70 is connected to the standing platform 60 and is configured to adjust the standing platform 60 in the stand-on mower's posture so that the standing surface always supports the user in a substantially vertical, upward position. Specifically, the standing surface changes its position relative to the stand-on mower as the stand-on mower's posture changes. When the stand-on mower is operating on a slope, the left and right wheels of the stand-on mower may differ in height, causing the stand-on mower and the standing platform 60 to tilt. In this situation, the balancing device 70 can adjust the standing platform 60's posture in the left and right directions, allowing the user to maintain a stable position on the standing platform 60.

[0086] As shown in Figures 6 and 7, in some embodiments, the standing platform 60 includes two split pedals 61 spaced apart along the left and right sides of the stand-on lawn mower. A balancing device 70 is capable of adjusting the height of the two split pedals 61. When the stand-on lawn mower tilts, the balancing device 70 can automatically adjust the height of the two split pedals 61 based on the weight of the user's feet to maintain the user's standing stability. Optionally, the balancing device 70 includes a support member 71, a connecting rod 72, and two damping members 73. The support member 71 is fixedly mounted on the frame 10. The middle portion of the connecting rod 72 is rotatably supported on the support member 71. The rotation axis of the connecting rod 72 is a third axis 701. The two ends of the connecting rod 72 are respectively connected to the two split pedals 61. The two damping members 73 correspond one-to-one with the two split pedals 61. One end of the damping member 73 is connected to the frame 10, and the other end of the damping member 73 is connected to the split pedal 61. The structure of the connecting rod 72 connected to the two split pedals 61 is similar to that of a seesaw. When one split pedal 61 descends, the other split pedal 61 rises accordingly. When the stand-on lawn mower tilts, the weight of the human body causes one split pedal 61 to sink, while the connecting rod 72 drives the other split pedal 61 upward, achieving the effect of traveling on a slope while the human body remains upright. The connecting rod 72 is V-shaped, with the opening of the connecting rod 72 facing upward, so that the rotation of the connecting rod 72 is not interfered with by the support member 71. The support member 71 is a leaf spring that provides a cushioning force for the standing platform 60, making it more comfortable for the user to stand on.

[0087] As shown in Figure 8, in some embodiments, the standing platform 60 is an integral pedal 62, and the balancing device 70 is capable of adjusting the tilt angle of the integral pedal 62 along the left and right directions of the stand-on lawn mower. Optionally, the balancing device 70 includes a support plate 74 and two side plates 75. The support plate 74 is fixedly mounted on the vehicle frame 10, the integral pedal 62 is positioned above the support plate 74, and the two side plates 75 are connected between the integral pedal 62 and the support plate 74. The integral pedal 62, the support plate 74, and the two side plates 75 form a trapezoidal structure. At least one side plate 75 is capable of rotating relative to the support plate 74 and the integral pedal 62 to adjust the tilt angle of the integral pedal 62. A vehicle posture detection device is provided on the support plate 74. The vehicle posture detection device is configured to identify the posture of the stand-on lawn mower and control the rotation of the side plates 75 based on the posture of the stand-on lawn mower. The vehicle posture detection device is a gyroscope sensor.

[0088] There are two ways to adjust the integrated pedal 62. In the first embodiment, both side panels 75 are capable of rotating relative to the support plate 74 and the integrated pedal 62. Initially, the side panels 75 are locked. When the vehicle posture detection device detects that the stand-on lawn mower's lateral tilt angle exceeds a set tilt angle, the side panels 75 are unlocked, and the integrated pedal 62 is allowed to swing freely under the influence of the user's gravity, allowing the user to stand upright stably. In the second embodiment, only one side panel 75 is capable of rotating relative to the support plate 74. The rotation of this side panel 75 is adjusted by an active adjustment mechanism. The active adjustment mechanism can be configured as a motor plus a worm gear. The worm gear is mounted on the output shaft of the motor, and the worm is connected to the side panel 75. The worm gear converts the motor's rotation into the rotation of the side panel 75. The worm gear has a self-locking function, which can lock the side panel 75 at a certain angle. Of course, the above is merely an example, and the structure of the adjustment mechanism is not limited to this. Any structure that can drive the side panel 75 to rotate and has a locking function is acceptable. As long as the vehicle posture detection device detects that the stand-on lawn mower has deviated to the side, the active adjustment mechanism will control the rotation angle of the side panel 75 in real time according to the side tilt angle of the stand-on lawn mower, and then adjust the angle of the integral pedal 62 so that the user can stand upright stably.

[0089] As shown in Figure 9, the counterweight device 80 includes at least a counterweight 81 that is movable relative to the frame 10. The movement direction of the counterweight 81 is aligned with the front-to-back direction of the stand-on lawn mower. The counterweight device 80 is configured to adjust the position of the counterweight 81 based on the weight of the user on the standing platform 60, thereby adjusting the center of gravity of the stand-on lawn mower and ensuring proper load distribution between the front and rear axles. Optionally, the device also includes a center of gravity offset determination unit configured to obtain a center of gravity offset signal of the stand-on lawn mower. The counterweight device 80 is configured to automatically adjust the position of the counterweight 81 based on the center of gravity offset signal. The stand-on lawn mower also includes a warning device configured to issue an alarm when the stand-on lawn mower's center of gravity offsets.

[0090] The user's weight is measured by a weight measurement device, which is located on the standing platform 60. The counterweight 81 is driven and moved by a drive assembly. The drive assembly includes a drive motor, a lead screw, and a guide limit rod. The lead screw and the guide limit rod are arranged in parallel. The counterweight 81 is slidably connected to the guide limit rod and threadedly connected to the lead screw. The drive motor is configured to drive the lead screw to rotate, thereby driving the counterweight 81 to move axially along the guide limit rod. The above structure of the drive assembly is merely illustrative and is not intended to be limiting.

[0091] The above shows and describes 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 form, and any technical solutions obtained by equivalent replacement or equivalent transformation fall within the scope of protection of this application.
