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 degree (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).
[0070] In this application, it will be understood by those skilled in the art that the function performed by a component can be performed by one component, multiple components, or multiple parts, or can also be performed by one part.

[0082] Reference Figure 1 and Figure 2 As shown, the support mechanism includes a standing platform 60, and the standing platform 60 has a standing plane, and the standing plane is used to support the user. The standing platform 60 is arranged at the rear of the frame 10, connected to the frame 10, and located between the two rear running wheels 22. In some embodiments, the standing platform 60 is partially located between the two rear running wheels 22, and one end of the standing platform 60 close to the front running wheel 21 is located between the axis of the front running wheel 21 and the rear running wheel 22. In this way, when the user stands on the standing platform 60, the center of gravity of the human body is located at the center of the axis of the rear running wheel 22 of the standing lawn mower. When the standing lawn mower rotates, there is no rotation radius, no centrifugal force is generated, and there is no danger of being thrown out. In addition, when the standing platform 60 moves forward, the center of gravity of the human body also moves forward accordingly, whether climbing a slope or passing through a pothole ground, it can be safer and not easy to overturn.
[0083] The balancing device 70 is connected to the standing platform 60 and is used to adjust the posture of the standing platform 60 in the standing lawn mower so that the standing plane always supports the user vertically upward, that is, the standing plane changes its position relative to the standing lawn mower when the posture of the standing lawn mower changes. When the standing lawn mower is running on a slope, the heights of the left and right wheels of the standing lawn mower are different, causing the standing lawn mower and the standing platform 60 to tilt. At this time, the posture of the standing platform 60 along the left and right directions of the standing lawn mower can be adjusted by the balancing device 70, so that the user can still stand stably on the standing platform 60.
[0084] Reference Figure 6 and Figure 7 As shown, in some embodiments, the standing platform 60 includes two split pedals 61, and the two split pedals 61 are spaced apart along the left and right directions of the standing lawn mower, and the balancing device 70 can adjust the height of the two split pedals 61. When the standing lawn mower tilts, the balancing device 70 can automatically adjust the height of the two split pedals 61 according to the gravity of the user's feet to maintain the stability of the user's standing. Specifically, the balancing device 70 includes a supporting member 71, a connecting rod 72 and two damping members 73, the supporting member 71 is fixedly arranged on the frame 10, the middle part of the connecting rod 72 is rotatably supported on the supporting member 71, the rotation axis of the connecting rod 72 is the 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 are respectively corresponding to 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 after the connecting rod 72 is connected to the two split pedals 61 is similar to the structure of a seesaw. When one of the split pedals 61 drops, the other split pedal 61 will rise accordingly. When the stand-up lawn mower tilts, due to the weight of the human body, the split pedal 61 on one side will sink, and at the same time, the split pedal 61 on the other side will rise through the connecting rod 72, so that the human body can still stand vertically while walking on the slope. Among them, the connecting rod 72 is V-shaped, and the opening of the connecting rod 72 faces upward, so that the rotation of the connecting rod 72 will not be interfered by the support member 71. Among them, the supporting member 71 is a leaf spring to provide a buffering force for the standing platform 60, so that the user is more comfortable standing on it.
[0085] Reference Figure 8As shown, in some embodiments, the standing platform 60 is an integral pedal 62, and the balancing device 70 can adjust the inclination angle of the integral pedal 62 along the left and right directions of the standing lawn mower. Specifically, the balancing device 70 includes a support plate 74 and two side plates 75, the support plate 74 is fixedly arranged on the frame 10, the integral pedal 62 is located above the support plate 74, the two side plates 75 are connected between the integral pedal 62 and the support plate 74, and the integral pedal 62, the support plate 74 and the two side plates 75 are combined to form a trapezoidal structure, and at least one side plate 75 can rotate relative to the support plate 74 and the integral pedal 62, so as to adjust the inclination angle of the integral pedal 62. A vehicle posture detection device is arranged on the support plate 74, and the vehicle posture detection device is used to identify the posture of the standing lawn mower and control the rotation of the side plates 75 according to the posture of the standing lawn mower. The vehicle posture detection device is a gyroscope sensor.
[0086] There are two ways to adjust the integral pedal 62. The first implementation is that both side panels 75 can rotate relative to the support plate 74 and the integral pedal 62. Initially, the freedom of the side panel 75 is locked. When the vehicle posture detection device detects that the side tilt angle of the stand-up lawn mower exceeds the set tilt angle, the freedom of the side panel 75 is opened, and the integral pedal 62 is freely swung and adjusted under the action of the user's gravity, so that the user can stand upright stably. The second implementation is that only one side panel 75 can rotate relative to the support plate 74, and the rotation of the side panel 75 is adjusted by an active adjustment mechanism. The structure of the active adjustment mechanism can be set in the form of a motor plus a worm gear. The worm gear is set on the output shaft of the motor, and the worm is connected to the side panel 75. The worm gear can convert the rotation of the motor into the rotation of the side panel 75, and the worm gear has a self-locking function, which can lock the side panel 75 at a certain angle. Of course, the above is only an exemplary description, and the structure of the adjustment mechanism is not limited to this. As long as it can achieve the drive of the side panel 75 to rotate and has any structure with a locking function, it can be used. 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 deviation 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.
