The travel assembly 12 may include at least one first travel wheel 121 and at least one second travel wheel 122, such as two second travel wheels 122, namely a left second travel wheel 122L and a right second travel wheel 122R. The first travel wheel 121 is configured to rotate freely. The first travel wheel 121 has a first diameter; the second travel wheel 122 has a second diameter larger than the first diameter. The travel assembly 12 may also include at least one travel motor 123, such as two travel motors 123, namely a left travel motor 123L and a right travel motor 123R, for driving the second travel wheels 122. In this way, when the two travel motors 123 drive the corresponding second travel wheels 122 to rotate at different speeds, a speed difference is created between the two second travel wheels 122, thereby causing the ride-on lawnmower 100 to steer. The travel motors 123 are controlled by the travel control module 124. In some embodiments, the movement control module 124 includes a control chip, such as an MCU or an ARM processor. In one embodiment, the two movement control modules 124 control two movement motors 123 respectively.

[0132] Power supply assembly 14 is configured to supply power to the ride-on lawnmower 100. Power supply assembly 14 is configured to supply power to at least the cutting motor 112 and the travel motor 123. Power supply assembly 14 may also supply power to other electronic components in the ride-on lawnmower 100, such as the cutting control module 113 and the travel control module 124. Power supply assembly 14 may also supply power to the lighting assembly 18. In some embodiments, power supply assembly 14 is disposed behind the seat 15 on the chassis 16. In some embodiments, power supply assembly 14 includes a plurality of battery packs 141 capable of supplying power to the ride-on lawnmower 100.

[0133] In one configuration, the power supply assembly 14 includes six battery packs 141 disposed on the rear side of the seat 15. The six first battery packs 141 are arranged in a battery compartment 142 on the rear side of the seat 12. Furthermore, the battery compartment 142 is divided into six sub-battery compartments 143, in which the six battery packs 141 are installed. More specifically, the six battery packs 141 are arranged in three rows and two columns. The dimensions of the battery packs 141 in the lateral direction are larger than their dimensions in the longitudinal direction. Therefore, the dimensions of the six battery packs 141 arranged in three rows and two columns are not too large in the longitudinal direction, thus not increasing the longitudinal dimension of the ride-on lawnmower 100, and are not too small in the lateral direction, thus effectively utilizing the space occupied by the ride-on lawnmower 100 in the lateral direction. Therefore, the power supply assembly 14 provides sufficient battery capacity to power the ride-on lawnmower 100, and the arrangement of the power supply assembly 14 is reasonable and space-saving. Other configurations may also be used if suitable.

[0134] The operating component 13 is user-operable, and the user sends control commands through the operating component 13 to control the operation of the ride-on lawnmower 100. The user can operate the operating component 13 to set the cutting speed, travel speed, and travel direction of the ride-on lawnmower 100. In other words, the user can operate the operating component 13 to set the operating state of the ride-on lawnmower 100, which includes cutting state and travel state.

[0135] Operating component 13 may include at least one triggerable switch to change its state, thereby setting the ride-on lawnmower 100 to different states. In one embodiment, a seat switch (not shown) disposed under seat 15 is configured to set the ride-on lawnmower 100 to an startable state when a user is seated on the seat, and to set the ride-on lawnmower 100 to an inactive state when no one is seated on the seat. Start button 133 is configured to start the ride-on lawnmower 100 when the user presses start button 133, and to stop the ride-on lawnmower 100 when the user presses start button 133 again. Key switch 134 is configured to start the travel motor 123 when the user inserts a key and rotates the key to the ON position, and to stop the travel motor 123 when the user rotates the key to the OFF position or removes the key. Blade actuator 135 is configured to rotate the cutting member 111 when the user lifts the blade actuator 135 and to stop the cutting member 111 when the user presses down on the blade actuator 135. The start button 133, key switch 134, and blade actuator 135 can be arranged on the left cover member 162L or the right cover member 162R so that the user's hand can easily reach them when the user is seated on the seat 15. In one embodiment, the start button 133, key switch 134, and blade actuator 135 are all arranged on the right cover member 162R, and the left cover member 162L is left open so that when the user jumps onto the ride-on lawnmower 100 from the left side, the user can place one hand on the left cover member 162L.

[0136] The operating assembly 13 may further include a combination of one or more operating mechanisms, such as pedals, levers, handles, and a steering wheel. In one embodiment, the pedal assembly 131, combined with the steering wheel assembly 136, is configured to provide a system for the user to at least control the movement of the riding lawnmower 100. The pedal assembly 131 controls the speed of the riding lawnmower 100, and the steering wheel assembly 136 controls the direction of movement of the riding lawnmower 100.

[0137] The steering wheel assembly provided in this application has a smaller packaging size during the transport and storage of ride-on lawnmowers, allowing users to more easily jump on and off the ride-on lawnmower, and providing a larger field of vision when seated on the ride-on lawnmower. The steering wheel assembly provided in this application also improves the functional safety of the operating components and the anti-fogging effect of the display interface device.

[0138] In one embodiment, the steering wheel assembly 136 includes: a steering wheel 1362 operable to rotate about a first axis 107; and a connecting rod 1361 configured to connect the steering wheel 1362 and a chassis 16. The connecting rod 1361 has a first end 2201 connected to the steering wheel 1362 and a second end 2202 connected to the chassis 16. In one embodiment, the steering wheel assembly 136 further includes a pivoting assembly 1368 rotatably connecting the connecting rod 1361 and the chassis 16. In one embodiment, the pivoting assembly 1368 rotatably connects the second end 2202 of the connecting rod 1361 to the chassis. See also Figure 2 and Figure 5 The pivot assembly 1368 includes a first part 2101 fixedly connected to the chassis and a second part 2102 fixedly connected to a second end 2202 of the connecting rod 1361. The first part 2101 and the second part 2102 are movably connected to each other, for example, by a hinge structure. Therefore, the pivot assembly 1368 allows the steering wheel assembly 136 to be switched between a working position and a stored position. It should be understood that the pivot assembly 1368 may also be provided in other parts of the connecting rod 1361 to allow at least a portion of the connecting rod 1361 to rotate, thereby achieving the same function of switching the steering wheel assembly 136 between a working position and a stored position.

[0139] like Figure 1 As shown, in the working position, the connecting rod 1361 is erected to lift the steering wheel 1362, so that when the user is sitting upright in the seat, the user can comfortably hold the steering wheel 1362 with both hands. Figure 2 As shown, in the storage position, the connecting rod 1361 is laid flat on the chassis 16, so that the ride-on lawnmower 100 occupies less space during storage and transportation. When the steering wheel assembly 136 is in the storage position, the distance between the steering wheel 1362 and the plane on which the ride-on lawnmower 100 travels is less than the distance between the steering wheel 1362 and the plane when the steering wheel assembly 136 is in the working position. Figure 5 As shown, in one configuration, to secure the steering wheel assembly 136 in a working position, the first part 2101 and the second part 2102 of the pivot assembly 1368 are secured to each other by at least one fastener (e.g., four long bolts). Figure 2As shown, in one configuration, to place the steering wheel assembly 136 in the storage position, at least one fastener is released, allowing the first part 2101 and the second part 2102 of the pivot assembly 1368 to rotate relative to each other. It should be noted that the transition between the storage and operating positions of the steering wheel assembly 136 is not very rapid, as such transitions are not frequently required, and the disclosed structure ensures a stable and reliable connection between the second end 2202 of the connecting rod 1361 and the chassis 16, thereby improving the mechanical reliability of the steering wheel assembly 136. Furthermore, the disclosed structure also features low production and maintenance costs.

[0140] In some embodiments, the second end 2202 of the pedal assembly 131 and the connecting rod 1361 are located on the same side of the central vertical plane 109 passing through the central axis 106 of the ride-on lawnmower 100. In one configuration, to accommodate the driving habits of most users, the pedal assembly 131 is arranged on the right side of the central vertical plane 109, allowing the user to operate the pedal assembly 131 effortlessly. In this case, the second end 2202 of the connecting rod 1361 is also arranged on the right side of the central vertical plane 109. In one embodiment, the connecting rod 1361 is arranged on the right side of the central vertical plane 109. In one embodiment, the second end 2202 of the connecting rod 1361 is mounted on the right side of the ride-on lawnmower 100. In one embodiment, the second end 2202 of the connecting rod 1361 is connected to a pivot assembly 1368, and the pivot assembly 1368 is mounted to the right longitudinal beam 161R of the chassis 16. Aligning the second ends 2202 of the pedal assembly 131 and the connecting rod 1361 on the same side of the central vertical plane 109 ensures unobstructed access on the other side of the central vertical plane 109, thus reducing obstacles encountered when the user jumps onto the ride-on lawnmower 100 from the other side of the central vertical plane 109. Furthermore, the connecting rod 1361 provides some protection for the user's feet extending to the pedal assembly 131.

[0141] In one embodiment, when the steering wheel assembly 136 is in the operating position, the cover covers the pivot assembly 1368. In one embodiment, the right cover member 162R covers the pivot assembly 1368. In some embodiments, the left cover member 162L and the right cover member 162R have a similar height to the seating surface of the seat 15; in one embodiment, the left cover member 162L and the right cover member 162R have a lower height relative to the seating surface of the seat 15. In addition to their covering function, the left cover member 162L and the right cover member 162R may support at least one of the operating components or accessories that are easily accessible to the user's hands when the user is seated in the seat 15. In one embodiment, the left cover member 162L or the right cover member 162R may provide a cup holder 2301 to accommodate the user's cup; the left cover member 162L or the right cover member 162R may provide a mobile phone holder 2302 to accommodate the user's mobile phone; the left cover member 162L or the right cover member 162R may provide a charging port 2303 to charge the user's electronic device (such as a mobile phone) during operation. The left cover member 162L and the right cover member 162R may also provide triggers, switches, or buttons, i.e., components of the operating assembly 13, thereby allowing the user to operate the ride-on lawnmower 100 more conveniently.

[0142] In some embodiments, the left cover member 162L and the right cover member 162R are not symmetrical. As previously mentioned, due to the obstruction of the operating assembly 13 on the other side of the ride-on lawnmower 100, namely the obstruction of the connecting rod 1361 of the steering wheel assembly 136 on the right side of the ride-on lawnmower 100, the user may prefer to jump onto the ride-on lawnmower 100 from one side (i.e., the left side of the ride-on lawnmower 100). Therefore, the left cover member 162L has a lower height than the right cover member 162R. However, to balance the overall structure of the ride-on lawnmower 100, the height of the left cover member 162L should not be too low. Reference Figure 18 In one embodiment, the vertical distance D1 from the left cover member 162L to the plane of travel of the riding lawnmower 100 is greater than or equal to 45 cm and less than or equal to 65 cm. In another embodiment, the vertical distance D1 from the left cover member 162L to the plane of travel of the riding lawnmower 100 is greater than or equal to 50 cm and less than or equal to 60 cm. In yet another embodiment, the vertical distance D1 from the left cover member 162L to the plane of travel of the riding lawnmower 100 is approximately 55 cm. In one embodiment, the left cover member 162L has a sloping top surface, i.e., the height of its front side is lower than the height of its rear side, such that the overall height of the left cover member 162L is lower than the overall height of the right cover member 162R. In this way, the user can more easily jump onto the riding lawnmower 100 from the left side.

[0143] Furthermore, reducing the distance a user needs to traverse before sitting down can also alleviate the difficulty of boarding the ride-on lawnmower 100 without sacrificing its width. In one embodiment, the vertical distance D2 from the outermost surface of the left cover member 162L to the central vertical plane 109 is greater than or equal to 30 cm and less than or equal to 50 cm. In one embodiment, the vertical distance D2 from the outermost surface of the left cover member 162L to the central vertical plane 109 is greater than or equal to 30 cm and less than or equal to 50 cm. In one embodiment, the vertical distance D2 from the outermost surface of the left cover member 162L to the central vertical plane 109 is greater than or equal to 35 cm and less than or equal to 45 cm. In one embodiment, the vertical distance from the outermost surface of the left cover member 162L is approximately 39 cm. Additionally, for taller users with longer legs, the area for boarding and alighting from the ride-on lawnmower 100 should be sufficiently wide. (Reference) Figure 19 In one embodiment, the distance D3 between the orthographic projections of the front end of the riding lawnmower 100 and the rear end of the left cover member 162L onto the plane in which the riding lawnmower 100 travels is greater than or equal to 100 cm and less than or equal to 130 cm. In one embodiment, the distance D3 between the orthographic projections of the front end of the riding lawnmower 100 and the rear end of the left cover member 162L onto the plane in which the riding lawnmower 100 travels is greater than or equal to 110 cm and less than or equal to 120 cm. In one embodiment, the distance D3 between the orthographic projections of the front end of the riding lawnmower 100 and the rear end of the left cover member 162L onto the plane in which the riding lawnmower 100 travels is approximately 115 cm. Figure 18-20 The image shows a user who is 1.9m tall; for users who are shorter or have shorter legs, the area for the user to get on and off the riding lawnmower 100 is more spacious.

[0144] To further assist users in boarding the ride-on lawnmower 100, in some embodiments, such as Figure 20As shown, the riding lawnmower 100 also includes a foot pedal 163 mounted to the chassis 16, wherein the foot pedal 163 is located on the opposite side of the central vertical plane 109 relative to the pedal assembly. In one embodiment, the steering wheel assembly 136 and the pedal assembly are mounted on the left side of the riding lawnmower 100, while the foot pedal 163 is mounted on the right side of the riding lawnmower 100. In one embodiment, the foot pedal 163 is mounted to the right longitudinal beam 161R. In one embodiment, the foot pedal 163 is foldable; specifically, the foot pedal 163 is rotatably mounted to the right longitudinal beam 161R via a hinge structure. The foot pedal 163 has a first position and a second position: in the first position, the foot pedal 163 is parallel to the chassis, wherein the foot pedal 163 extends from the right longitudinal beam 161R, and the user can step on the foot pedal 163 when mounting the ride-on lawnmower 100; in the second position, the foot pedal 163 is perpendicular to the chassis, wherein the foot pedal 163 is close to the right longitudinal beam 161R to save space.

[0145] In one embodiment, the operating component 13 further includes a control panel 137. The control panel 137 may include multiple buttons, each corresponding to a different command. The buttons on the control panel 137 may include a lighting button configured to enable or disable the lighting component 18, a mode button configured to select and set the riding mode of the mower 100, a configuration button configured to modify various settings of the mower 100, and a speed regulator button to increase or decrease the travel speed or cutting speed of the mower 100. The operating component 13 may also include a display interface device 138 that displays the operating status of the mower 100. The display interface device 138 may display the travel speed of the travel component, the rotation speed of the cutting component, the energy efficiency status of the mower 100, the remaining capacity of the power supply component 14, warning messages, fault information, etc.

[0146] In one configuration, the control panel 137 and display interface device 138 are integrated with the steering wheel assembly 136. (See reference) Figure 6The control panel 137 is arranged at the center of the steering wheel 1362, and the display interface device 138 is arranged at the center of the control panel 137. In one configuration, the steering wheel 1362 is substantially symmetrical about a second axis 108; the control panel 137 is also substantially symmetrical about the second axis 108; and the display interface device 138 is also substantially symmetrical about the second axis 108. In one configuration, the buttons of the control panel 137 are distributed around the display interface device 138. In one configuration, the display interface device 138 is substantially rectangular, with a length dimension L2 greater than or equal to 100 mm and less than or equal to 150 mm, and a width dimension L3 greater than or equal to 60 mm and less than or equal to 90 mm. The area of ​​the display interface device 138 is greater than or equal to 70 square centimeters and less than or equal to 110 square centimeters. In this way, the size of the display interface device 138 is large enough to display sufficient information, and simultaneously small enough to be fitted at the center of the control panel 137, which is fitted at the center of the steering wheel 1362. In one embodiment, the display interface device 138 may also be an interactive display interface device capable of receiving user commands. The user inputs different control commands through the control panel 137 and / or the display interface device 138 to control the movement and cutting functions of the ride-on lawnmower 100.

[0147] refer to Figure 6 Unlike a traditional circular steering wheel 1362, the outer frame of the steering wheel 1362 is more oval in shape. In this way, on the one hand, the outer frame of the steering wheel 1362 more evenly surrounds the rectangular display interface device 138 or control panel 137, leaving approximately equal distances between the outer frame of the steering wheel 1362 and the control panel 137, thus providing the user with more options on which part of the steering wheel 1362 to grip or hold. On the other hand, unlike a circle, an ellipse does not have a uniform diameter; therefore, the outer frame of the steering wheel 1362 has a larger dimension defined as its width and a smaller dimension defined as its height. The larger dimension allows the steering wheel 1362 to have sufficient width, making it more comfortable for the user to grip the steering wheel 1362 with both hands; the smaller dimension allows the steering wheel 1362 to have a lower height, thus preserving a clearer field of vision for the user.

[0148] Furthermore, a notch 2203 is formed on the top side of the steering wheel 1362, wherein the notch 2203 is also substantially symmetrical about the second axis 108. The notch 2203 further eliminates obstruction in the user's line of sight, ensuring an unobstructed view. The outer frame of the steering wheel 1362 is interrupted by the notch 2203, and the shape of the interrupted end is suitable for the user's grip. In one embodiment, the notch 2203 may be replaced by a transparent portion. That is, the outer frame of the steering wheel 1362 remains continuous, but the top side of the steering wheel 1362 is made of a transparent material. In one embodiment, the length of the notch 2203 or the transparent portion is greater than or equal to 1 / 10 of the circumference of the steering wheel 1362 and less than or equal to 1 / 2 of the circumference of the steering wheel 1362. In another embodiment, the length of the notch 2203 or the transparent portion is greater than or equal to 1 / 9 of the circumference of the steering wheel 1362 and less than or equal to 1 / 3 of the circumference of the steering wheel 1362.

[0149] To further expand the user's field of vision, the steering wheel assembly 136 has been carefully positioned within the working position. (Reference) Figure 21 The height of the steering wheel assembly 136 can be defined as the vertical distance D4 from the highest point of the steering wheel assembly 136 to the plane of travel of the riding lawnmower 100. A lower steering wheel assembly 136 provides better visibility for the user; however, if the steering wheel assembly 136 is too low, the user experience may be affected. In one embodiment, when the steering wheel assembly 136 is in the working position, the vertical distance D4 from the highest point of the steering wheel assembly 136 to the plane of travel of the riding lawnmower 100 is greater than or equal to 85 cm and less than or equal to 125 cm. In another embodiment, when the steering wheel assembly 136 is in the working position, the vertical distance D4 from the highest point of the steering wheel assembly 136 to the plane of travel of the riding lawnmower 100 is greater than or equal to 95 cm and less than or equal to 115 cm. In one embodiment, when the steering wheel assembly 136 is in the working position, the vertical distance D4 from the highest point of the steering wheel assembly 136 to the plane in which the riding lawnmower 100 travels is approximately 105 cm.

[0150] Similarly, the height difference between the steering wheel assembly 136 and the seat surface (i.e., the height difference between the steering wheel assembly 136 and the seat surface) also affects the user's field of vision. A smaller height difference results in better visibility; however, if the height difference is too small, legroom may be insufficient, leading to an uncomfortable seating experience. In one embodiment, when the steering wheel assembly 136 is in the working position, the difference D5 between the vertical distance from the highest point of the steering wheel assembly 136 to the plane of travel of the riding lawnmower 100 and the vertical distance from the seat surface to the plane of travel of the riding lawnmower 100 is greater than or equal to 30 cm and less than or equal to 55 cm. In another embodiment, when the steering wheel assembly 136 is in the working position, the difference D5 between the vertical distance from the highest point of the steering wheel assembly 136 to the plane of travel of the riding lawnmower 100 and the vertical distance from the seat surface to the plane of travel of the riding lawnmower 100 is greater than or equal to 35 cm and less than or equal to 50 cm. In one embodiment, when the steering wheel assembly 136 is in the working position, the difference D5 between the vertical distance from the highest point of the steering wheel assembly 136 to the plane of travel of the riding lawnmower 100 and the vertical distance from the seat surface to the plane of travel of the riding lawnmower 100 is approximately 42 cm.

[0151] Furthermore, assuming the user is seated with the backrest in the riding lawnmower 100, the distance between the steering wheel assembly 136 and the seat backrest may also affect the user's field of vision. The closer the distance between the steering wheel assembly 136 and the seat backrest, the better the user's field of vision. However, if the distance between the steering wheel assembly 136 and the seat backrest is too small, the seating area is too small or the steering wheel assembly 136 is too close to the user's chest, resulting in an uncomfortable seating or operating experience. In one embodiment, when the steering wheel assembly 136 is in the working position, the distance D6 between the orthographic projections of the steering wheel assembly 136 and the seat backrest on the plane of travel of the riding lawnmower 100 is greater than or equal to 60 cm and less than or equal to 100 cm. In another embodiment, when the steering wheel assembly 136 is in the working position, the distance D6 between the orthographic projections of the steering wheel assembly 136 and the seat backrest on the plane of travel of the riding lawnmower 100 is greater than or equal to 70 cm and less than or equal to 90 cm. In one embodiment, when the steering wheel assembly 136 is in the working position, the distance D6 between the orthographic projection of the steering wheel assembly 136 and the seat back onto the plane of travel of the riding lawnmower 100 is approximately 80 cm.

[0152] In one embodiment, the seat 15 is adjustable in the fore-and-aft direction of the riding lawnmower 100. Figure 21 The image depicts an eye position range of 1001 to represent the possible eye positions for users at different heights. Figure 21The user depicted is 1.9m tall, so his eyes are located in the upper part of the eye position range. A tall user's eyes can be located at point A, so the line of sight from point A is 1002A, and the user can observe an area farther than 1002A, making the area between 1002A and the ride-on lawnmower 100 a blind spot. A short user's eyes can be located at point B, so the line of sight from point B is 1002B, and the user can observe an area farther than 1002B, making the area between 1002B and the ride-on lawnmower 100 a blind spot. The blind spot of the short user is larger than that of the tall user; that is, compared to the short user, the tall user can observe the lawn closer to the ride-on lawnmower 100. To alleviate this problem, the ride-on lawnmower 100 is also equipped with an adjustment device to move the seat 15 in the forward and backward direction of the ride-on lawnmower 100. Therefore, if the user operates the adjustment device to move the seat 15 forward, the eyes of the shorter user, who was originally at point B, will move to point C. Thus, the line of sight from point C is 1002C, and the user can observe an area farther than 1002C, making the area between 1002C and the ride-on lawnmower 100 (i.e., the blind spot) smaller.

[0153] In one embodiment, the operating component 13 further includes an operating member 139, which can be operated by a user to control at least one control circuit 130 of the ride-on lawnmower 100. Specifically, the control circuit 130 has at least a first state 1301 that allows the travel motor 123 to start and a second state 1302 that prevents the travel motor 123 from starting. When the ride-on lawnmower is powered on, i.e., when the key is inserted and rotated to the ON position, the control circuit 130 is in the second state 1302, and the operating member 139 is operable to switch the control circuit 130 to the first state 1301. In some embodiments, the operating member 139 is at least one paddle shifter 139. (See reference...) Figure 5-7The operating component 139 is a pair of paddle shifters 139, namely a left paddle shifter 139L and a right paddle shifter 139R. The steering wheel assembly 136 also includes a mounting assembly rotatably connecting the steering wheel 1362 and the connecting rod 1361. In one configuration, the paddle shifters 139 are mounted to the steering wheel 1362. In another configuration, the paddle shifters 139 are mounted to the mounting assembly. In one embodiment, the left paddle shifter 139L and the right paddle shifter 139R are mounted on the housing or display interface device 138 of the control panel 137. The left paddle shifter 139L extends to the left side of the ride-on lawnmower 100, and the right paddle shifter 139R extends to the right side of the ride-on lawnmower 100. Thus, when the user holds the steering wheel 1362 with both hands, the left paddle shifter 139L can be activated by at least one finger of the left hand, and the right paddle shifter 139R can be activated by at least one finger of the right hand. When operating the paddle shifters 139, the user's hands do not need to leave the steering wheel 1362; therefore, operation of the paddle shifters 139 is convenient when the user is driving the ride-on lawnmower 100.

[0154] In one embodiment, the operating member 139 is connected to the switch 1391, and the operating member 139 is operable to actuate the switch 1391; when the switch 1391 is actuated by the operating member 139, the control circuit 130 is switched to a first state 1301. Specifically, as Figure 7 As shown, the left paddle shifter 139L is connected to a drive lever 1392. The drive lever 1392 has a first end 2201 connected to the left paddle shifter 139L and a second end 2202 connected to a contact (e.g., a quick-activate switch) of a switch 1391. When the left paddle shifter 139L is pressed, the drive lever 1392 presses the contact of the switch 1391, and the switch 1391 sends an activation signal to the control circuit 130. The same structure applies to the right paddle shifter 139R.

[0155] refer to Figure 17When the ride-on lawnmower is powered on, for example, when the key is inserted and rotated to the ON position, the control circuit 130 is in a second state 1302. In one embodiment, when the user operates the operating member 139 (i.e., at least one paddle shifter 139) to send a start signal, the control circuit 130 is switched to a first state 1301. In one embodiment, the control circuit 130 is switched to a first state 1301 when start signals are received from both the left paddle shifter 139L and the right paddle shifter 139R. In one embodiment, the control circuit 130 is switched to a first state 1301 when two start signals are received substantially simultaneously from both the left paddle shifter 139L and the right paddle shifter 139R, i.e., when the timestamps of the start signals from the left paddle shifter 139L and the right paddle shifter 139R have a time difference within a specific time threshold. In one embodiment, the ride-on lawnmower 100 also includes a start button 133, which, when pressed and actuated by the operating member 139, switches the control circuit 130 to a first state 1301. In the first state 1301, when moving forward, the user operates the pedal assembly 131 and the steering wheel assembly 136 to control the speed and direction of travel of the ride-on lawnmower 100.

[0156] In one embodiment, the control circuit 130 further has a third state 1303, in which the control circuit 130 stops the travel motor 123 and subsequently allows the travel motor 123 to rotate in the reverse direction. The operating member 139 is operable to switch the control circuit 130 to the third state 1303. The control circuit 130 is switched to the third state 1303 when the control circuit 130 is in the first state 1301 and at least one paddle shifter 139 remains pressed for a period greater than or equal to a first time threshold. In other words, if the user presses at least one paddle shifter for a period greater than or equal to the first time threshold, the ride-on lawnmower 100 switches from forward to backward movement. In some cases, even if the user presses at least one paddle shifter for a period of time greater than or equal to a first time threshold—that is, the user issues a reverse command via operating member 139—the reverse command is rejected if the ride-on lawnmower 100 is traveling too fast to safely execute the reverse command, and the display interface device 138 displays a warning that the ride-on lawnmower 100 is not allowed to reverse. Therefore, in one embodiment, when the control circuit 130 is in the first state 1301 and at least one paddle shifter remains pressed for a period of time greater than or equal to the first time threshold, the control circuit 130 determines whether the motor speed is less than or equal to a first speed threshold, and if the motor speed is less than or equal to the first speed threshold, the control circuit 130 is switched to the third state 1303.

[0157] During the transition from the first state 1301 to the third state 1303, or in other words, from forward movement to backward movement, the ride-on lawnmower 100 first decelerates in the forward direction until the speed reaches 0, and then accelerates in the backward direction; that is, the control circuit 130 first reduces the speed of the travel motor 123 until the speed of the travel motor 123 reaches 0, and then reverses the rotation of the travel motor 123. In the third state 1303, when moving in reverse, the user also operates the pedal assembly 131 and the steering wheel assembly 136 to control the speed and direction of travel of the ride-on lawnmower 100. It should be noted that the maximum speed of the motor when the control circuit 130 is in the third state 1303 is less than the maximum speed of the motor when the control circuit 130 is in the first state 1301. Furthermore, the maximum turning angle of the ride-on lawnmower when the control circuit 130 is in the third state 1303 is less than the maximum turning angle of the motor when the control circuit 130 is in the first state 1301. Therefore, when traveling in the opposite direction, the riding lawnmower 100 is not allowed to travel quickly or make sharp turns, thereby improving the safety of the riding lawnmower 100.

[0158] When the control circuit 130 is in the third state 1303 and at least one paddle shifter 139 is released, the control circuit 130 is switched to the first state 1301. In other words, if the user releases at least one paddle shifter 139, the ride-on lawnmower 100 switches from backward movement to forward movement. That is, when the ride-on lawnmower 100 is moving backward, the user needs to keep at least one paddle shifter 139 pressed. In the process of switching from the third state 1303 to the first state 1301, or in other words, from backward movement to forward movement, the ride-on lawnmower 100 first decelerates in the backward direction until the speed reaches 0, and then accelerates in the forward direction; that is, the control circuit 130 first reduces the speed of the travel motor 123 until the speed of the travel motor 123 reaches 0, and then rotates the travel motor 123 forward.

[0159] In one embodiment, the ride-on lawnmower 100 provides the user with different driving modes. In one embodiment, the user can select a driving mode via a mode button. Different driving modes are configured with different responsiveness, thus providing the user with a range of driving experiences to choose from. In one embodiment, the ride-on lawnmower 100 has a standard mode, a control mode, and a sport mode. The acceleration of the control circuit 130 switching from a first state 1301 to a third state 1303 varies among the multiple driving modes. Of the three driving modes, the sport mode is configured to have the fastest acceleration, therefore, the transition from forward to backward or from backward to forward in the sport mode is the fastest. The standard mode is configured to have a slower acceleration than the sport mode, therefore, the transition from forward to backward or from backward to forward in the standard mode is slower. Of the three driving modes, the control mode is configured to have the slowest acceleration, therefore, the transition from forward to backward or from backward to forward in the control mode is the slowest.

[0160] In related technologies, due to the effects of high temperature and high humidity, gardening tools on the market (such as ride-on lawnmowers) are prone to fogging on their displays. As a result, users cannot clearly see the data or numbers displayed on the screen, leading to a poor user experience.

[0161] refer to Figure 13-14 The display interface device 138 includes a housing 1381, a screen layer 1380 housed within the housing 1381, and a printed circuit board 1385. The screen layer 1380 may be an LCD screen or an LED screen, which is not limited herein. Since the detailed optical configuration of the screen itself is not the focus of this disclosure, the screen layer 1380 is simplified for descriptive purposes. In one embodiment, the screen layer 1380 includes an intermediate layer 1383 and a back layer 1384. The intermediate layer 1383 forms a light path for guiding and converting backlight. The intermediate layer 1383 may include LED strips, a polarizer layer, a liquid crystal layer, a color filter layer, and a light guide plate (not shown). The back layer 1384 may be a reflective sheet for reflecting backlight. The backlight arrangement may be edge LEDs or direct-lit LEDs, which is not limited herein. The housing 1381 includes a cover layer 1382, which is a transparent protective cover for protecting and displaying the screen layer 1380. The cover layer 1382, the intermediate layer 1383, the back layer 1384 and the printed circuit board 1385 are stacked and mounted to the housing 1381, that is, the intermediate layer 1383 is disposed below the cover layer 1382, the back layer 1384 is disposed below the intermediate layer 1383, and the printed circuit board 1385 is disposed below the back layer 1384.

[0162] In one embodiment, the housing 1381 of the display interface device 138 includes a frame for a cover layer 1382 and a plurality of reserved openings for buttons on the control panel 137; in other embodiments, the housing 1381 does not include openings for buttons or switches. In this embodiment, the frame is integrally formed with the housing 1381; in other embodiments, the frame may be a separate part embedded in the housing 1381. In one embodiment, the back layer 1384 has ribs 2004 projecting toward a printed circuit board 1385. The ribs 2004 lift the back layer 1384 above the printed circuit board 1385; and the back layer 1384 presses the intermediate layer 1385 against the housing 1381. In one embodiment, the printed circuit board 1385 is mounted to the housing 1381 by at least one fastener (e.g., a screw). In one embodiment, the printed circuit board 1385 is integrated with the switches for the buttons on the control panel 137, such that the printed circuit board 1385 transmits not only graphic signals for the display interface device 138 but also on / off signals for the buttons on the control panel 137.

[0163] In one embodiment, a cover layer 1382 is also attached to a housing 1381. The cover layer 1382 may be made of tempered glass or transparent polycarbonate (PC) material, while the housing 1381 may be made of other materials. Both sides of the cover layer 1382 are coated with at least one coating, such as a nano-coating. The nano-coating makes the cover layer 1382 waterproof and dustproof, so that water and dust in the air will not easily contaminate the display interface device 138 when the ride-on lawnmower 100 is in operation, allowing the user to clearly observe the display interface device 138 throughout the mowing process. In some embodiments, multiple coatings are applied to the cover layer 1382 to ensure the effectiveness and durability of the coatings. Furthermore, in some embodiments, at least one protective film is applied to the cover layer 1382 to prevent scratches or damage to the coating and / or the cover layer 1381.

[0164] refer to Figure 13The cover layer 1382 includes a protrusion 2001 extending from its side surface. The housing 1381 includes a mating portion 2002 for engaging with the protrusion 2001 of the cover layer 1382. In one embodiment, the mating portion 2002 includes two edges, an upper edge 2002A and a lower edge 2002B. The upper edge 2002A and the lower edge 2002B form a groove 2003 between them. The protrusion 2001 of the cover layer 1382 engages with the groove 2003 of the housing 1381 to mount the cover layer 1382 to the housing 1381. In one embodiment, the cover layer 1382 is encapsulated together when it is embedded in the housing 1381. In another embodiment, the housing 1381 and the cover layer 1382 are a single piece, i.e., the housing 1381 and the cover layer 1382 are integrated together. In one embodiment, the housing 1381 is made of tempered glass or transparent polycarbonate (PC) material. Reference Figure 15 The housing 1381 can be assembled onto gardening tools or power tools using fasteners (such as screws).

[0165] In one embodiment, an adhesive, particularly a flexible adhesive such as silicone, is applied between the screen layer 1380 and the housing 1381. Flexible adhesives can accommodate differences in the coefficients of thermal expansion of the adhered materials, thus reducing the risk of damage and aging. In one configuration, the flexible adhesive is applied to fill the space between the rib portion 2004 and the inner wall of the housing 1381 to form a seal that seals the cavity between the housing 1381 and the screen layer 1380. This cavity includes at least the space between the cover layer 1382 and the screen layer 1380. In some other configurations, the rib portion 2004 may be arranged at other locations on the screen layer 1380, for example, on the side surface of the screen layer 1380. It should be understood that the specific location of the flexible adhesive application may vary slightly depending on the specific configuration of the display interface device 138, such as the housing 1381, cover layer 1382, screen layer 1380, etc., and this is not limited herein.

[0166] In one embodiment, a double seal is created to securely seal the space between the cover layer 1382 and the screen layer 1380. For example... Figure 14As shown, a flexible adhesive is applied to fill the space between the lower surface of the lower edge 2002B and the upper surface of the intermediate layer 1383, thereby forming a first seal 2011. Furthermore, a flexible adhesive is applied to fill the space between the rib portion 2004 of the back layer 1384 and the inner wall of the housing 1381, thereby forming a second seal 2012. Depending on the specific construction of the display interface device 138, such as the housing 1381, cover layer 1382, intermediate layer 1383, back layer 1384, etc., the specific locations where the first seal 2011 and the second seal 2012 are applied may differ slightly, which is not limited herein. Sealed by the first seal 2011, a first chamber 2013 is formed between the cover layer 1382 and the screen layer 1830, specifically, between the cover layer 1382 and the intermediate layer 1383. Sealed by a first seal 2011 and a second seal 2012, a second chamber 2014 is formed between the inner wall of the housing 1381 and the side surface of the screen layer 1830, specifically, between the inner wall of the housing 1381 and the side surfaces of the intermediate layer 1383 and the back layer 1384. The first chamber 2013 and the second chamber 2014 are adjacent to each other.

[0167] To ensure the rigidity of the cover layer 1382, in one configuration, the thickness of the cover layer 1382 is greater than or equal to 2 mm and less than or equal to 5 mm. Alternatively, the thickness of the cover layer 1382 is greater than or equal to 3 mm and less than or equal to 4 mm. In one embodiment, the thickness of the cover layer 1382 is 3.5 mm. Because the cover layer 1382 in this disclosure is manufactured to be relatively thick, it is less prone to deformation, bending, or denting. As a result, the distance D7 between the cover layer 1382 and the screen layer 1830, specifically, the distance D7 between the cover layer 1382 and the intermediate layer 1383 (i.e., the height of the first chamber 2013), can be relatively small. In one embodiment, the distance D7 between the cover layer 1382 and the screen layer 1830 can be greater than or equal to 0.1 mm and less than or equal to 3 mm. Alternatively, the distance D7 between the cover layer 1382 and the screen layer 1830 can be greater than or equal to 0.2 mm and less than or equal to 2 mm. In one embodiment, the distance D7 between the cover layer 1382 and the screen layer 1830 is 0.3 mm.

[0168] The smaller distance between the cover layer 1382 and the screen layer 1830 means that the height of the first chamber 2013 is smaller, and therefore the volume of air sealed by the first seal 2011 in the first chamber 2013 is smaller. The smaller volume of air sealed between the cover layer 1382 and the screen layer 1830 contains very little moisture, making it less prone to liquefaction, which mitigates the fogging problem of the display interface device 138. However, over time, the anti-fogging effect largely depends on the durability of the seals (i.e., the first seal 2011 and the second seal 2012). If the seals become aged and cracked, moisture from the environment may enter the first chamber 2013, causing fogging on the display interface device 138. On the one hand, the first seal 2011 and the second seal 2012 provide dual protection. If the second seal breaks but the first seal is still functional, the first seal can still seal the first chamber; if the first seal breaks but the second seal is still functional, the second seal can still seal the space of the first chamber plus the second chamber. On the other hand, the first chamber 2013 and the second chamber 2014 play a role in balancing forces.

[0169] When the ambient temperature changes, if the ambient temperature is high, the air sealed in the first chamber 2013 expands; if the ambient temperature is low, the air sealed in the first chamber contracts, thus generating thrust (when expanding) and tension (when contracting) on ​​the first seal 2011. Over time, this impairs the reliability and durability of the first seal 2011. However, due to the small height of the first chamber 2013, the volume of air sealed by the first seal 2011 in the first chamber 2013 is small, thus limiting the force exerted on the first seal 2011 by the thermal expansion and contraction of the air in the first chamber 2013. Furthermore, some air is also sealed in the second chamber 2014 between the inner wall of the housing 1381 and the side surface of the screen layer 1830, which is sealed by the first seal 2011 and the second seal 2012. When the ambient temperature changes, if the ambient temperature is high, the air sealed in the second chamber 2014 also expands, and if the ambient temperature is low, the air contracts. In other words, the air sealed in the second chamber 2014 expands and contracts substantially synchronously with the air sealed in the first chamber 2013. Since the first chamber 2013 and the second chamber 2014 are adjacent and share the first seal 2011 as a common boundary, the force exerted on the first seal 2011 by the thermal expansion and contraction of the air in the second chamber 2014 at least partially offsets the force exerted on the first seal 2011 by the thermal expansion and contraction of the air in the first chamber 2013. This results in the first seal 2011 experiencing less thrust and tension during temperature changes, making it more durable. The above structure is simple, compact, and highly reliable, forming a self-contained display assembly that is easy to assemble, maintain, and replace. It should be understood that this structure is not limited to displays on ride-on lawnmowers; it is also suitable for displays on other power tools for fog-proof purposes.

[0170] In one embodiment, the display interface device 138 may not include the screen layer 1380. That is, the display interface device 138 does not have an LED screen or an LCD screen. Instead, as Figure 16As shown, the display interface device 138 includes a housing 1381 and a printed circuit board 1385 housed within the housing 1381. The housing 1381 may be made of tempered glass or polycarbonate (PC) material, and the thickness of the housing 1381 is greater than 2 mm and less than or equal to 5 mm. The printed circuit board has multiple light-emitting elements 1388, such as LED beads. The display interface device 138 also includes a light guide layer 1389 etched with light guide channels. The light guide layer 1389 may be a separate component or integrally formed with the housing 1381 as a single piece. A label (not shown) may be adhered to the housing 1381 or the light guide layer 1388 to further improve the display effect. To prevent fogging, a flexible adhesive is applied between the printed circuit board 1385 and the housing 1381 to seal the cavity, which includes at least the space between the printed circuit board 1385 and the housing 1381. The independently sealed display interface device 138 can then be assembled onto various gardening tools or power tools.

[0171] In one embodiment, the steering wheel assembly 136 includes a rotation axis 1367 configured to rotate synchronously with the steering wheel 1362. A mounting assembly rotatably connects the steering wheel 1362 and the connecting rod 1361; in one embodiment, the mounting assembly rotatably supports the rotation axis 1367. (Reference) Figure 7 The mounting assembly also includes a mounting housing 1364, which is fixedly connected to the connecting rod 1361 and rotatably supports the rotating shaft 1367. The mounting housing 1364 may be formed in two halves, and these two halves enclose a first end 2201 of the connecting rod 1361. The rotating shaft 1367 is fixedly coupled to the steering wheel 1362. When the user turns the steering wheel 1362, the rotating shaft 1367 rotates synchronously with the steering wheel 1362. In one embodiment, both the steering wheel 1362 and the rotating shaft 1367 rotate about a first axis 107. In one configuration, the steering wheel 1362 has a base plate 1386 and a fixing plate 1369, wherein the fixing plate 1369 is secured to the base plate 1386 by a plurality of fasteners. The rotating shaft 1367 engages, for example, with at least one of the fixing plate 1369 and the base plate 1386 via a flat fit. Figure 9 As shown, the substrate 1386 has double D-holes, the fixing plate 1369 also has double D-holes, and the rotating shaft 1367 has a double D-section, which is fitted into the double D-holes of the fixing plate 1369 and the substrate 1386. In one embodiment, the rotating shaft 1367 is welded to the fixing plate 1369, thereby rotating synchronously with the fixing plate 1369. This structure ensures a stable connection between the rotating shaft 1367 and the steering wheel 1362.

[0172] In one configuration, the mounting assembly further includes a support member 1365 and at least one bearing. The support member 1365 is housed within a mounting housing 1364; in one embodiment, the support member 1365 is also secured to a first end 2201 of the connecting rod 1361, for example, by a fastening device. The support member 1365 is formed with a channel for a rotating shaft 1367 and at least one bearing housing for the at least one bearing. The at least one bearing is mounted to the support member 1365, and the rotating shaft 1367 is rotatably supported by the at least one bearing. In one embodiment, two bearings respectively support the upper portion and the lower portion of the rotating shaft 1367. The specific structure of the support member 1365 is not limited herein, as long as it supports the rotating shaft 1367 and enables the rotating shaft 1367 to rotate. In fact, the support member 1365 is not necessary if the mounting housing 1364 is formed with a corresponding structure to rotatably support the rotating shaft 1367.

[0173] In another embodiment, the steering wheel assembly 136 includes an adjustment device operable to adjust the height of the steering wheel 1362. The adjustment device allows at least one of the support member 1365 and the mounting box 1364 to move vertically relative to the connecting rod 1361, while the position of the adjustment device is fixed relative to the connecting rod 1361. In one embodiment, the support member 1365 is formed in a cylindrical shape, and the adjustment device can be fixed to different positions on the cylinder. When the adjustment device is fixed to a lower position on the cylinder, the height of the steering wheel 1362 is relatively high; when the adjustment device is fixed to a higher position on the cylinder, the height of the steering wheel 1362 is relatively low.

[0174] In one embodiment, the rotating shaft 1367 has a through-hole that allows a cable or wire to pass through. One end of the cable is connected to a first circuit board 1387, and the other end is connected to a second circuit board. In one embodiment, the second circuit board is a printed circuit board 1385 of the display interface device 138. In one embodiment, reference... Figure 7The wire 1393 of the switch 1391, which is connected to the operating member 139, is connected to the printed circuit board 1385 to reduce the number of wires. In one embodiment, the wire 1393 of the switch 1391 connected to the left paddle shifter 139L is connected to the printed circuit board 1385, and the wire 1393 of the switch 1391 connected to the right paddle shifter 139R is also connected to the printed circuit board 1385. Therefore, the printed circuit board 1385 carries the switching signals of the operating member 139, the graphic signals of the display interface device 138, and the switching signals of the buttons on the control panel 137. Thus, only one cable (i.e., the cable connected to the printed circuit board 1385) is configured to pass through, making the wiring simple and clean. Since the cable is located within the through hole of the rotation shaft 1367, the cable is less prone to wear, thereby extending the service life of the steering wheel assembly 136.

[0175] In one embodiment, the rotation shaft 1367 is coupled to a magnetic element, and the first circuit board 1387 has a position sensor that detects the angular position of the magnetic element. In one configuration, the magnetic element is suspended from the lower end of the rotation shaft 1367 and rotates synchronously with the rotation shaft 1367, and the first circuit board 1387 is located below the magnetic element, with the position sensor directly facing the magnetic element. Other configurations are also acceptable as long as the position sensor detects the angular position of the steering wheel 1362 and the first circuit board 1387 receives the position signal detected by the position sensor. Since the cable connects the first circuit board 1387 and the second circuit board, the first circuit board 1387 carries not only the angular position signal of the steering wheel 1362, but also the switching signals of the operating member 139, the graphic signals of the display interface device 138, and the switching signals of the buttons of the control panel 137. In addition, another cable is connected to the first circuit board 1387 and passes through the connecting rod 1361, so that other components of the ride mower 100 (such as the travel assembly 12, the lighting assembly 18, and the cutting assembly 11) can exchange information with the steering wheel assembly 136, the control panel 137, and the display interface device 138.

[0176] In one embodiment, the mounting plate 1369 includes a stop protrusion 2103 to limit the angle of rotation of the steering wheel 1362. The stop protrusion 2103 may be formed in the shape of a hook protruding from the surface of the mounting plate 1369. The mounting box 1364 or support member 1365 also includes a mating protrusion 2104 protruding from the mounting box 1364 to limit the position of the stop protrusion 2103. Figure 9-10As shown, the support member 1365 is mounted to the mounting box 1364 by at least one fastener (e.g., two bolts), and these two bolts are fastened to one side of the channel for the rotating shaft 1367. When the support member 1365 is assembled to the mounting box 1364, the heads of the two bolts protrude from the mounting box 1364, where the bolt heads are examples of mating protrusions 2104, and there are two mating protrusions 2104. In the direction of the first axis 107, the distance between the mounting box 1364 and the fixing plate 1369 is less than the sum of the dimensions of the stop protrusion 2103 protruding from the fixing plate 1369 and the dimensions of the mating protrusion 2104 protruding from the mounting box 1364 (i.e., the height of the two bolt heads). Furthermore, the distance from the stop protrusion 2103 to the first axis 107 and the distance from the mating protrusion 2104 to the first axis 107 are approximately the same.

[0177] refer to Figure 11A In one embodiment, when the user turns the steering wheel 1362 clockwise, the retaining plate 1369 rotates until the stop protrusion 2103 reaches one of the two matching protrusions 2104. When the user turns the steering wheel 1362 counterclockwise, the retaining plate 1369 rotates until the stop protrusion 2103 reaches the other of the two matching protrusions 2104. In one embodiment, reference... Figure 11B At least one fastener is a bolt, thus there is only one mating protrusion 2104. The mounting plate 1369 can rotate either clockwise or counterclockwise until the stop protrusion 2103 reaches the mating protrusion 2104. In this embodiment, at least one fastener performs the dual functions of mounting the support member 1365 to the mounting box 1364 and limiting the position of the stop protrusion 2103, thereby limiting the angle of rotation of the steering wheel 1362. Furthermore, the at least one fastener is robust, durable, inexpensive, and easy to replace. However, in other embodiments, the mating protrusion 2104 is not a fastener; in fact, the mating protrusion 2104 can be any protruding structure configured to limit the rotational position of the stop protrusion 2103.

[0178] Due to the stop protrusion 2103 and the matching protrusion 2104, the steering wheel 1362 has a first limit position 2111 when rotating clockwise around the first axis, such as Figure 12A As shown, and having a second extreme position 2112 when rotating counterclockwise around the first axis, as... Figure 12BAs shown. In one embodiment, the steering wheel 136 rotates from the first extreme position 2111 to the second extreme position 2112 by an angle less than or equal to 380 degrees. In one embodiment, the steering wheel 136 rotates from the first extreme position 2111 to the second extreme position 2112 by an angle less than or equal to 320 degrees. In one embodiment, the steering wheel 136 rotates from the first extreme position 2111 to the second extreme position 2112 by an angle less than or equal to 240 degrees. In one embodiment, the steering wheel 136 rotates from the first extreme position 2111 to the second extreme position 2112 by an angle of 270 degrees. Since the steering wheel 1362 is configured to rotate clockwise and counterclockwise by the same angle, the angles from the first extreme position 2111 to the second extreme position 2112 can be equally separated. In other words, the steering wheel 1362 also has an initial position 2113, wherein the steering wheel 1362 is symmetrical about the second axis 108. In one embodiment, the angle α1 from the initial position 2113 to the first extreme position 2111 is less than or equal to 190 degrees, and the angle α2 from the initial position 2113 to the second extreme position 2112 is less than or equal to 190 degrees. In another embodiment, the angle α1 from the initial position 2113 to the first extreme position 2111 is less than or equal to 160 degrees, and the angle α2 from the initial position 2113 to the second extreme position 2112 is less than or equal to 160 degrees. In yet another embodiment, the angle α1 from the initial position 2113 to the first extreme position 2111 is less than or equal to 120 degrees, and the angle α2 from the initial position 2113 to the second extreme position 2112 is less than or equal to 120 degrees. In one embodiment, the angle α1 of the steering wheel 136 rotating from the initial position 2113 to the first extreme position 2111 is 135 degrees, and the angle α2 of the steering wheel 136 rotating from the initial position 2113 to the second extreme position 2112 is 135 degrees.

[0179] In one embodiment, the steering wheel assembly 136 further includes a damper 2105, and the rotation shaft 1367 and the damper 2105 transmit force via a belt drive. In one embodiment, the damper 2105 is a rotary damper, or a disc damper. Figure 8As shown, the rotating shaft 1367 is connected to the geared member 2107. In one configuration, the geared member 2107 has double D-holes, which are fitted into the double D-section of the rotating shaft 1367. The damper 2105 is also connected to the gear 2108. In one configuration, the damper 2105 has a shaft 2109, and the gear 2108 is fixed to the shaft 2109 of the damper 2105. Both the geared member 2107 and the gear 2108 engage with a belt 2106. The belt 2106 transmits force from the geared member 2107 to the gear 2108 and from the gear 2108 to the geared member 2107. When the user turns the steering wheel 1362, the rotating shaft 1367 rotates, thereby causing the geared member 2107 to rotate. As the geared member 2107 rotates, the belt rotates and transmits rotational force to the gear 2108 and the shaft. When the shaft rotates, the viscosity of the sealing oil in the damper body will create resistance to the movement of the shaft 2109. This resistance (or viscous friction) will slow down the movement of the steering wheel 1362. As the damper 2105 moves, its torque is generally affected by the viscosity of the sealing oil. When the user releases the steering wheel 1362, the resistance generated by the viscosity of the sealing oil drives the shaft to its initial position, and the steering wheel 1362 thus rotates to its initial position 2113. In one embodiment, to ensure effective force transmission between the rotating shaft 1367 and the shaft 2109 of the damper 2105, the belt 2106 is also provided with a tensioning device 2110. In one embodiment, at least a portion of the damper 2105 and the belt drive is housed within a support member 1365, which provides better fixation and protection. It should be noted that the specific structure of the damper 2105 is not limited herein; and in some embodiments, the damper 2105 may be replaced by a motor to provide the damping effect. Furthermore, if a motor is used to provide the damping effect, the angular position of the steering wheel 1362 can be calculated based on the rotational position of the motor and the transmission ratio of the belt drive, thereby eliminating the need for additional sensors to detect the angular position of the steering wheel 1362.

[0180] This disclosure also applies to other types of riding machines, as long as the riding machine can output power in a form other than walking power to achieve functions other than walking, for example, Figure 22 The ride-on snow blower 200 shown also adopts the same or similar design as the above embodiments.
