[0052] The central control mechanism 50 includes a control component, which is used to control at least the operation of the first motor and the second motor. The central control mechanism 50 also includes an operating table 51 for an operator to operate to control the stand-up lawn mower. An operating part is provided on the operating table 51, and the operating part is configured to be held by the operator to at least control the walking direction and walking speed of the stand-up lawn mower. The walking directions of the stand-up lawn mower include forward, backward, left turn and right turn.

[0053] Reference Figure 2In some embodiments, the operating part includes an operating member 52, and the operating member 52 is configured to be held by an operator with one hand to at least control the walking direction and walking speed of the stand-up lawn mower. Specifically, the operating member 52 includes a straight rod portion 521, and the lower end of the straight rod portion 521 is rotatably connected to the operating table 51. To facilitate the operator's holding, the operating member 52 also includes a ball head 522, and the ball head 522 is arranged at the upper end of the straight rod portion 521. The operator can hold the ball head 522 with one hand to operate the operating member 52. Rotating the operating member 52 forward can control the stand-up lawn mower to move forward, rotating the operating member 52 backward can control the stand-up lawn mower to move backward, rotating the operating member 52 to the left can control the stand-up lawn mower to turn left, and rotating the operating member 52 to the right can control the stand-up lawn mower to turn right. In some embodiments, the forward and backward walking speeds of the stand-up lawn mower can be controlled by adjusting the forward and backward amplitudes of the operating member 52. In some embodiments, the angle at which the stand-on lawn mower turns left or right can be controlled by adjusting the left and right amplitudes of the operating member 52. In some embodiments, the control component can output control instructions based on the actions on the operating member 52, and the control instructions include forward / backward instructions, turning instructions, and zero turn instructions.

[0054] A support member 53 is also provided on the operating table 51, and the support member 53 is configured to be supported by the operator with one hand. The operating part only includes one operating member 52, and the operating member 52 is configured to be held by the operator with one hand to at least control the walking direction and walking speed of the stand-up lawn mower, so that the operator's other hand can always hold the support member 53 to maintain body balance, without changing hands, and the operation is simple. In some embodiments, the support member 53 and the operating member 52 are spaced apart along the left and right directions of the stand-up lawn mower, which is ergonomic and more convenient for the operator to hold the operating member 52 with one hand and the support member 53 with the other hand. In some embodiments, the support member 53 is L-shaped, including a first vertical portion 531 and a first horizontal portion 532, and the end of the first vertical portion 531 away from the first horizontal portion 532 is fixedly connected to the operating table 51, and the first horizontal portion 532 extends and distributes in the direction close to the operating member 52. Such a configuration is convenient for the operator to hold on the one hand, and on the other hand, it can shorten the distance between the two hands, making the operation more comfortable.

[0055] Reference Figure 3In some embodiments, the operating part includes a pair of driving rods 54, and the pair of driving rods 54 are configured to be held by the operator with both hands to at least control the walking direction and walking speed of the stand-up lawn mower. Specifically, the pair of driving rods 54 are both L-shaped, and both include a second vertical portion 541 and a second horizontal portion 542. The two second vertical portions 541 are both rotatably arranged on the operating table 51, and the two second horizontal portions 542 extend toward each other. The operator's hands can be respectively held on the two second horizontal portions 542 to operate the pair of driving rods 54. In some embodiments, the operator can control the stand-up lawn mower to move forward by rotating the pair of driving rods 54 forward at the same time, and can control the stand-up lawn mower to move backward by rotating the pair of driving rods 54 backward at the same time. Only rotating the left driving rod 54 forward can control the stand-up lawn mower to turn left, and only rotating the right driving rod 54 forward can control the stand-up lawn mower to turn right. In some embodiments, the operator can control the walking speed of the stand-up lawn mower by adjusting the rotation amplitude of the driving rod 54. In some embodiments, the control assembly can output control commands based on the actions on the drive rod 54 , the control commands including forward / reverse commands, turn commands, and zero turn commands.

[0056] In some embodiments, the pair of driving rods 54 are further configured to be operated by the operator to have at least a first position open to both sides and a second position closed to the middle. The control component is configured to allow the current in the power supply device 40 to flow to the first motor when at least a first signal of the driving rod 54 switching from the second position to the first position and a second signal of the driving rod 54 switching from the first position to the second position are detected in sequence. This arrangement is used to achieve the purpose of safe starting and avoid the problem of the stand-on lawn mower walking rashly due to the operator accidentally touching the driving rod 54.

[0057] The operating table 51 is also provided with an operator interface, which includes a display screen 55 having a display plane. In some embodiments, the projection of the drive rod 54 on the first plane when it is in the second position overlaps at least partially with the projection of the display plane on the first plane. In some embodiments, the display plane is substantially parallel or substantially perpendicular to the first plane. The first plane in the above embodiment is substantially parallel to the ground plane where the walking assembly 20 is located. When a pair of drive rods 54 are in the first position, that is, when the drive rods 54 are opened, the display screen 55 can be operated. With such a configuration, the structure on the operating table 51 is more compact and will not affect the operation of the display screen 55.

[0058] Reference Figure 4The drive rod 54 is arranged on the operating table 51 through an opening and closing structure 56. The opening and closing structure 56 is configured to support the drive rod 54 to rotate along the front-to-back direction of the stand-up lawn mower to control the walking direction and walking speed of the stand-up lawn mower; the opening and closing structure 56 is also configured to support the drive rod 54 to rotate along the left-to-right direction of the stand-up lawn mower to switch the drive rod 54 between the first position and the second position. Specifically, the opening and closing structure 56 includes a first bracket 561, the lower end of the drive rod 54 is rotatably connected to the first bracket 561 through a first rotating shaft, the axis of the first rotating shaft is a first axis 501, and the first axis 501 extends along the front-to-back direction of the stand-up lawn mower. The drive rod 54 can rotate left and right around the first axis 501, thereby realizing the switching of the drive rod 54 between the first position and the second position. In some embodiments, a U-shaped frame 543 is provided at the lower end of the driving rod 54, a portion of the first bracket 561 is inserted into the U-shaped frame 543, and the first rotating shaft is sequentially arranged through one side wall of the U-shaped frame 543, the first bracket 561 and the other side wall of the U-shaped frame 543, so as to realize a stable connection between the driving 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 through a second rotating shaft, the axis of the second rotating shaft is the second axis 502, and the second axis 502 extends in the left and right direction of the stand-up lawn mower, and the driving rod 54 can rotate forward and backward around the second axis 502, so as to realize the control of the walking direction and walking speed of the stand-up lawn mower. The opening and closing structure 56 also includes two elastic members 563, both of which are arranged between the first bracket 561 and the second bracket 562 in a compressed state, and the two elastic members 563 are distributed on both sides of the second axis 502 along the front and rear direction of the stand-up lawn mower. When the operator operates the driving rod 54 to rotate forward and backward, the elastic member 563 can release a certain amount of damping, making the operation more convenient.

[0059] Reference Figure 1 The support mechanism includes a standing platform 60, which has a standing surface for supporting the operator. 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 operator 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 stand-up lawn mower. When the stand-up 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, it can be safer and not easy to overturn.

[0060] The balancing device 70 is connected to the standing platform 60 and is used to adjust the posture of the standing platform 60 so that the standing surface always supports the operator vertically upward, that is, the standing surface 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 operator can still stand stably on the standing platform 60.

[0061] Reference Figure 5 and Figure 6 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 operator's feet to maintain the stability of the operator'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. Preferably, 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 supporting member 71. Preferably, the supporting member 71 is a leaf spring to provide a buffering force for the standing platform 60, so that the operator is more comfortable standing on it.

[0062] Reference Figure 7In 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.

[0063] There are two ways to adjust the integral pedal 62. One 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 panels 75 is locked. When the vehicle posture detection device detects that the side tilt angle of the stand-on lawn mower exceeds the set tilt angle, the freedom of the side panels 75 is opened, and the integral pedal 62 is freely swung and adjusted under the action of the operator's gravity so that the operator can stand upright stably.

[0064] The other is that only one side plate 75 can rotate relative to the support plate 74, and the rotation of the side plate 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 gear is connected to the side plate 75. The worm gear can convert the rotation of the motor into the rotation of the side plate 75, and the worm gear has a self-locking function, which can lock the side plate 75 at an 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 side plate 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-up lawn mower has a lateral deviation, the active adjustment mechanism will control the rotation angle of the side plate 75 in real time according to the lateral deviation angle of the stand-up lawn mower, and then adjust the angle of the integral pedal 62 so that the operator can stand upright stably.

[0065] Reference Figure 8The counterweight device 80 at least includes a counterweight 81 that can move relative to the frame 10. The moving direction of the counterweight 81 is consistent with the front-rear direction of the stand-up lawn mower. The counterweight device 80 is configured to adjust the position of the counterweight 81 based on the weight of the operator on the standing platform 60, thereby adjusting the center of gravity position of the stand-up lawn mower to ensure the reasonable distribution of the front and rear axle loads. Preferably, it also includes a center of gravity offset judgment unit, which is configured to obtain a center of gravity offset signal of the stand-up lawn mower. The counterweight device 80 is configured to automatically adjust the position of the counterweight 81 based on the above center of gravity offset signal. It also includes a prompt device, which is configured to issue an alarm prompt when the center of gravity of the stand-up lawn mower is offset.

[0066] The operator's weight is measured by a weight measuring device, which is arranged on the standing platform 60. The counterweight 81 is driven to move by a driving assembly. The driving assembly includes a driving 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 is threadedly connected to the lead screw, and the driving motor is used to drive the lead screw to rotate, so as to drive the counterweight 81 to move along the axial direction of the guide limit rod. The above structure of the driving assembly is only an exemplary description and is not limited thereto.

[0067] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the above embodiments do not limit the present application in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the present application.
