Description

Technical Field

[0001] This invention relates to the field of lawnmower technology, and more particularly to an operating device for a riding lawnmower and a riding lawnmower. Background Technology

[0002] Lawn mowers are widely used as garden tools for trimming lawns and vegetation. Existing lawn mowers typically include handheld and ride-on models. Ride-on lawn mowers usually include a control device, which consists of a joystick. The joystick is typically arranged to move in both a first and second direction. The position of the joystick in each direction corresponds to different states of the drive motor and different operating states of the ride-on lawn mower. For example, the user can set the target speed of the drive motor by moving the joystick in the first direction, thus controlling the mower's travel speed. The user can also move the joystick in the second direction to put the ride-on lawn mower into or out of working mode (non-working mode).

[0003] In existing technologies, the control levers all rotate around a fixed axis in the first and second directions. Therefore, when the operator holds the control lever, the grip position is also rotating. Since the rotation span of the control lever in the first and second directions is large, the pure circular motion of rotation does not meet the optimal human-machine requirements. Summary of the Invention

[0004] The purpose of this invention is to provide an operating device for a riding lawnmower that can achieve a larger rotation angle for the same distance traveled.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an operating device for a riding lawnmower, comprising:

[0006] A support frame, which is mounted on a ride-on lawnmower;

[0007] A lever assembly includes a lever and a lever assembly. The lever is mounted on a bracket via the lever assembly. The lever is configured to move between an inner position and an outer position in a first direction, and between a front position, a middle position, and a rear position in a second direction.

[0008] A position detection device is used to detect the movement position of the control lever;

[0009] The movement of the operating lever in at least one of the first and second directions is a non-fixed pivot motion.

[0010] Furthermore, the movement of the operating lever in the first direction is a non-fixed-axis rotational movement.

[0011] Furthermore, the operating lever includes a gripping part and a moving part, with at least two moving parts provided. The moving parts cooperate with the lever assembly to form a planar compound motion.

[0012] Furthermore, the relative sliding trajectory formed by the moving part and the lever assembly is arc-shaped.

[0013] Furthermore, the lever assembly includes a first mating part that cooperates with the moving part. The moving part has two parts, namely a first sliding shaft and a second sliding shaft. The first mating part has two parts, namely a first sliding groove and a second sliding groove. Both the first and second sliding grooves are arc-shaped. When the operating rod moves in the first direction, the sliding direction of the first sliding shaft in the first sliding groove is opposite to the sliding direction of the second sliding shaft in the second sliding groove. Alternatively, the lever assembly includes a first mating part that cooperates with the moving part. The moving part has two parts, namely a first sliding groove and a second sliding groove. The first mating part has two parts, namely a first sliding shaft and a second sliding shaft. Both the first and second sliding grooves are arc-shaped. When the operating rod moves in the first direction, the sliding direction of the first sliding shaft in the first sliding groove is opposite to the sliding direction of the second sliding shaft in the second sliding groove.

[0014] Furthermore, the movement of the operating lever in the second direction is a non-fixed pivot motion.

[0015] Furthermore, the lever assembly includes a second mating part, and at least two second mating parts are provided. The second mating parts cooperate with the bracket to form a planar composite motion.

[0016] Furthermore, the relative sliding trajectory formed by the second mating part and the bracket is arc-shaped.

[0017] Furthermore, the second mating part is provided with two sliding grooves, namely a third sliding groove and a fourth sliding groove, and the bracket is provided with a third sliding shaft and a fourth sliding shaft. Both the third sliding groove and the fourth sliding groove are arc-shaped. When the operating rod moves in the second direction, the sliding direction of the third sliding shaft in the third sliding groove is opposite to the sliding direction of the fourth sliding shaft in the fourth sliding groove. Alternatively, the second mating part is provided with two sliding shafts, namely a third sliding shaft and a fourth sliding shaft, and the bracket is provided with a third sliding groove and a fourth sliding groove. Both the third sliding groove and the fourth sliding groove are arc-shaped. When the operating rod moves in the second direction, the sliding direction of the third sliding shaft in the third sliding groove is opposite to the sliding direction of the fourth sliding shaft in the fourth sliding groove.

[0018] The present invention also discloses a riding lawnmower, including any of the above-mentioned operating devices. The riding lawnmower further includes: a frame, a cutting system, a walking system, a seat assembly, a power supply device, and a control module. The walking system includes a front walking wheel, a rear walking wheel, and a first motor for driving the rear walking wheel. There are two first motors, each used to drive the two rear walking wheels. There are two operating devices, located on the left and right sides of the seat assembly, respectively, for controlling the two first motors.

[0019] By adopting the above technical solution, the present invention has the following advantages:

[0020] Non-fixed-axis motion refers to motion that is not achieved by rotating around a single fixed axis, as opposed to fixed-axis motion. By setting the motion of the control lever in at least one direction—first direction F1 and second direction F2—as non-fixed-axis motion, the movement trajectory of the control lever can be adjusted according to different user needs, improving the human-machine interface; and a larger rotation angle can be obtained for the same travel distance, making human-machine operation more convenient; furthermore, it avoids the swaying gap between the control lever and the lever assembly and / or the lever assembly and the support that occurs with fixed-axis motion, improving the user experience.

[0048] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the terms "upper," "lower," "left," "right," "longitudinal," "lateral," "inner," "outer," "vertical," "horizontal," "top," and "bottom," etc., which indicate orientation or positional relationships, are based solely on the orientation or positional relationships shown in the accompanying drawings and are used only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device / component referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present invention.

[0049] Example 1:

[0050] like Figure 1 As shown, the present invention provides an operating device 20 for a riding lawnmower. The operating device 20 has two parts (left operating device 20L and right operating device 20R), which are symmetrically located on both sides of the seat assembly. Since the left operating device 20L and the right operating device 20R have the same structure, the left operating device 20L will be mainly described as an example in this invention.

[0051] like Figure 2-8 As shown, the operating device 20 includes:

[0052] The bracket 21 is mounted on the ride-on lawnmower, specifically on the frame 11 of the ride-on lawnmower.

[0053] The control lever assembly includes a control lever 22 and a lever assembly 23. The control lever 22 is mounted on the bracket 21 via the lever assembly 23. The control lever 22 is configured to move between an inner position and an outer position in the first direction F1, i.e., the control lever can move in the P1 plane, and to move between a front position, a middle position and a rear position in the second direction F2, i.e., the control lever can move in the P2 plane.

[0054] Position detection device 26 is used to detect the movement position of operating lever 22;

[0055] The movement of the operating lever 22 in at least one of the first direction F1 and the second direction F2 is a non-fixed pivot motion.

[0056] Non-fixed-axis motion refers to motion that is not achieved by rotating around a single fixed axis, as opposed to fixed-axis motion. By setting the motion of the control lever in at least one direction—first direction F1 and second direction F2—as non-fixed-axis motion, the movement trajectory of the control lever can be adjusted according to different user needs, improving the human-machine interface; and a larger rotation angle can be obtained for the same travel distance, making human-machine operation more convenient; furthermore, it avoids the swaying gap between the control lever and the lever assembly and / or the lever assembly and the support that occurs with fixed-axis motion, improving the user experience.

[0057] In this embodiment, the movement of the operating lever 22 in the first direction F1 is a non-fixed pivot movement, and the movement of the operating lever 22 in the second direction F2 is a fixed pivot movement.

[0058] The control lever 22 includes a gripping part 221 and a moving part 222. At least two moving parts 222 are provided. The moving parts 222 cooperate with the lever assembly 23 to form a planar compound motion.

[0059] The relative sliding trajectory formed by the moving part 222 and the lever assembly 23 is arc-shaped.

[0060] In this embodiment, the lever assembly 23 includes a first mating part 232 that cooperates with the moving part 222. The moving part 222 has two sliding shafts, namely a first sliding shaft 281 and a second sliding shaft 282. The first mating part 232 has two sliding grooves, namely a first sliding groove 271 and a second sliding groove 272. Both the first sliding groove 271 and the second sliding groove 272 are arc-shaped. When the operating lever 22 moves in the first direction F1, the sliding direction of the first sliding shaft 281 in the first sliding groove 271 is opposite to the sliding direction of the second sliding shaft 282 in the second sliding groove 272. Taking the left operating device 20L as an example, when the operating lever 22 moves from the inner position to the outer position in the first direction F1, the first sliding shaft 281 moves from the inner side to the outer side of the first sliding groove 271, and the second sliding shaft 282 moves from the outer side to the inner side of the second sliding groove 272. Figure 6 As shown, the arc of the sliding trajectory of the first sliding shaft 281 in the first sliding groove 271 is as shown in Y1, and the arc of the sliding trajectory of the second sliding shaft 282 in the second sliding groove 272 is as shown in Y2. Figure 7 The motion coordination between the moving part and the first mating part in the first direction F1 is shown in more detail. A1, B1 and X1 are the centers of the first sliding shaft 281 and the second sliding shaft 282 and the instantaneous rotation center of the operating rod when the operating rod is in the outer position in the first direction F1, respectively. A2, B2 and X2 are the centers of the first sliding shaft 281 and the second sliding shaft 282 and the instantaneous rotation center of the operating rod when the operating rod is in the transition position in the first direction F1, respectively. A3, B3 and X3 are the centers of the first sliding shaft 281 and the second sliding shaft 282 and the instantaneous rotation center of the operating rod when the operating rod is in the inner position in the first direction F1, respectively. When the operating lever 22 moves from the outer to the inner position in the first direction F1, A1, A2, and A3 slide along the sliding trajectory Y1 of the first sliding shaft 281, which is an arc; B1, B2, and B3 slide along the sliding trajectory Y2 of the second sliding shaft 282, which is also an arc; the instantaneous rotation centers X1, X2, and X3 of the operating lever move along the curve G1, which is also an arc. It can be seen that the sliding trajectory of the moving part 222 has multiple centers, and there is not only rotation but also movement between the moving part and the first mating part, constituting a planar composite motion. By using two positioning points for positioning through the cooperation of the first sliding shaft and the first sliding groove, and the cooperation of the second sliding shaft and the second sliding groove, the wobbling gap between the operating lever and the lever assembly is avoided, improving the operating experience; from Figure 8 As can be seen, the included angle generated by the joystick during its movement is θ, and the opening is L. Under the same opening, the joystick using non-fixed pivot motion can obtain a larger rotation angle compared to fixed pivot motion, making human-machine operation more convenient. Furthermore, with non-fixed pivot motion, the included angle θ generated by the joystick during its movement in the first direction and the motion trajectory G2 of the joystick can be adjusted according to different user needs, improving the human-machine operation effect.

[0061] Springs 234 and damping pads 235 are fitted on both the first sliding shaft 281 and the second sliding shaft 282 to improve the reliability of the operating lever.

[0062] Understandably, the moving part can also be provided with multiple sliding shafts, and the first mating part can be provided with multiple sliding grooves.

[0063] like Figure 9-11 As shown, the movement of the operating lever 22 in the second direction F2 is a fixed-axis rotation movement.

[0064] Lever assembly 23 also includes a first fixed rotating shaft 236, and a first limiting hole is provided on bracket 21. The first fixed rotating shaft and the first limiting hole cooperate to realize the fixed rotating shaft movement of the operating rod in the second direction F2.

[0065] It is understandable that the bracket may have a first fixed rotating shaft and the lever assembly may have a first limiting hole. The first fixed rotating shaft and the first limiting hole may cooperate to realize the fixed rotating shaft movement of the operating rod in the second direction.

[0066] The bracket 21 includes an upper bracket 211 and a lower bracket 212. The lever assembly 23 is located within the installation space enclosed by the upper bracket 211 and the lower bracket 212. There is a swing gap between the lever assembly 23 and the upper and lower brackets for the lever assembly to swing in the second direction to satisfy the movement of the operating rod in the second direction. The upper bracket 211 is provided with a T-shaped clearance groove 2111 to avoid interfering with the movement of the operating rod in the first and second directions.

[0067] The lever assembly 23 includes a cover 231, a first mating part 232 and a first fixed rotating shaft 236, both of which are disposed on the cover 231. The cover 231 includes a front cover 2311 and a rear cover 2312. The moving part of the operating lever 22 is located within the installation space enclosed by the front cover 2311 and the rear cover 2312 and cooperates with the first mating part to realize the movement of the operating lever 22 between the inner and outer positions in the first direction.

[0068] Specifically, the front cover 2311 and the rear cover 2312 are each provided with a corresponding first sliding groove 271 and a second sliding groove 272 to improve the stability of the first sliding shaft 281 and the second sliding shaft 282 in their cooperation. The first fixed rotating shaft 236 is provided on the front cover 2311.

[0069] The operating device 20 is provided with a damping rod 24 in the second direction F2. One end of the damping rod 24 is connected to the frame 22 through a fixing piece 25, and the other end is connected to the cover 231 of the lever assembly. In this embodiment, the damping rod 24 is specifically connected to the rear cover 2312 of the cover 231.

[0070] The position detection device 26 includes a first detection device 261 for detecting the position of the operating lever 22 in the first direction F1 and a second detection device 262 for detecting the position of the operating lever 22 in the second direction F2. Specifically, the first detection device 261 is installed on the T-shaped clearance groove 2111 to facilitate the detection of the position of the operating lever in the first direction F1; the second detection device 262 is installed on the first fixed rotating shaft 236 to facilitate the detection of the position of the operating lever in the second direction F2.

[0071] Example 2:

[0072] The main difference between this embodiment and Embodiment 1 is that the arrangement of the first mating part and the moving part are different.

[0073] like Figure 12-16 As shown, in this embodiment, the lever assembly includes a first mating part 232 that cooperates with the moving part 222. The moving part 222 has two grooves, namely a first groove 271 and a second groove 272. The first mating part 232 has two sliding shafts, namely a first sliding shaft 281 and a second sliding shaft 282. Both the first groove 271 and the second groove 272 are arc-shaped. When the operating lever 22 moves in the first direction F1, the sliding direction of the first sliding shaft 281 in the first groove 271 is opposite to the sliding direction of the second sliding shaft 282 in the second groove 272. Taking the left operating device 20L as an example, when the operating lever 22 moves from the inner position to the outer position in the first direction F1, the first sliding shaft 281 moves from the outer side to the inner side of the first groove 271, and the second sliding shaft 282 moves from the inner side to the outer side of the second groove 272.

[0074] Specifically, springs 234 and damping pads 235 are fitted on both the first sliding shaft 281 and the second sliding shaft 282 to improve the reliability of the operating lever.

[0075] Understandably, the moving part can also be provided with multiple and multiple sliding grooves, and the first mating part can be provided with multiple and multiple sliding shafts.

[0076] Both the front cover 2311 and the rear cover 2312 are provided with fixing holes, and the first sliding shaft 281 and the second sliding shaft 282 are installed on the cover body 231 through the fixing holes.

[0077] Example 3:

[0078] The main difference between this embodiment and the above embodiments is that the movement of the operating lever in the first direction is a fixed-axis movement, while the movement of the operating lever in the second direction is a non-fixed-axis movement.

[0079] like Figures 17 to 20 As shown, the movement of the operating lever 22 in the first direction F1 is a fixed-axis movement, and the movement of the operating lever 22 in the second direction F2 is a non-fixed-axis movement.

[0080] The lever assembly 23 includes a second mating part 233, and at least two second mating parts 233 are provided. The second mating parts 233 cooperate with the bracket 21 to form a planar composite motion.

[0081] The relative sliding trajectory formed by the second mating part 233 and the bracket 21 is arc-shaped.

[0082] Specifically, the second mating part 233 is provided with two grooves, namely a third groove 273 and a fourth groove 274. The bracket 21 is provided with a third sliding shaft 283 and a fourth sliding shaft 284. Both the third groove 273 and the fourth groove 274 are arc-shaped. When the operating lever 22 moves in the second direction F2, the sliding direction of the third sliding shaft 283 in the third groove 273 is opposite to the sliding direction of the fourth sliding shaft 284 in the fourth groove 274. When the operating lever 22 moves from the rear position to the front position in the second direction F2, the third sliding shaft 283 moves from the front to the rear of the third groove 273, and the fourth sliding shaft 284 moves from the rear to the front of the fourth groove 274. There is not only rotation but also movement between the second mating part and the bracket, constituting a planar composite motion. By using the cooperation of the third sliding shaft and the third sliding groove, and the cooperation of the fourth sliding shaft and the fourth sliding groove, two positioning points are used for positioning, which avoids the wobbling gap between the lever assembly and the bracket and improves the operating experience. In addition, the operating lever can obtain a larger rotation angle in the second direction F2 for the same movement distance, making human-machine operation more convenient. Furthermore, the included angle generated by the operating lever during movement and the movement trajectory of the operating lever in the second direction F2 can be adjusted according to the needs of different users, thereby improving the human-machine operation effect.

[0083] It is understandable that the second mating part may have two parts, namely a third sliding shaft and a fourth sliding shaft, and the bracket may have a third sliding groove and a fourth sliding groove. Both the third sliding groove and the fourth sliding groove are arc-shaped. When the operating rod moves in the second direction, the sliding direction of the third sliding shaft in the third sliding groove is opposite to the sliding direction of the fourth sliding shaft in the fourth sliding groove.

[0084] Understandably, the second mating part can also be provided with multiple sliding grooves, and the bracket is provided with multiple corresponding sliding shafts.

[0085] Understandably, the second mating part can also be provided with multiple sliding shafts, and the bracket is provided with multiple corresponding sliding grooves.

[0086] Lever assembly 23 also includes a second fixed rotating shaft 237, and the operating rod is provided with a second limiting hole. The second fixed rotating shaft and the second limiting hole cooperate to realize the fixed rotating shaft movement of the operating rod in the first direction F1.

[0087] A spring and damping washer are fitted on the second fixed rotating shaft to improve the reliability of the operating lever.

[0088] It is understandable that the operating lever is provided with a second fixed rotating shaft and the lever assembly is provided with a second limiting hole. The second fixed rotating shaft and the second limiting hole cooperate to realize the fixed rotating shaft movement of the operating lever in the first direction.

[0089] Example 4:

[0090] The main difference between this embodiment and the above embodiments is that the movement of the operating lever in the first and second directions is a non-fixed pivot motion.

[0091] like Figures 21 to 23 As shown, the lever assembly 23 includes a first mating part 232 and a second mating part 233. The moving part is provided with two grooves, namely a first groove and a second groove. The first mating part 232 is provided with two sliding shafts, namely a first sliding shaft 281 and a second sliding shaft 282. Both the first groove and the second groove are arc-shaped. When the operating lever 22 moves in the first direction F1, the sliding direction of the first sliding shaft 281 in the first groove is opposite to the sliding direction of the second sliding shaft 282 in the second groove.

[0092] It is understandable that the two moving parts are the first sliding shaft and the second sliding shaft, and the two first mating parts are the corresponding first sliding groove and the second sliding groove.

[0093] The second mating part 233 is provided with two grooves, namely the third groove 273 and the fourth groove 274. The bracket 21 is provided with the third sliding shaft 283 and the fourth sliding shaft 284. The third groove 273 and the fourth groove 274 are both arc-shaped. When the operating lever 22 moves in the second direction F2, the sliding direction of the third sliding shaft 283 in the third groove 273 is opposite to the sliding direction of the fourth sliding shaft 284 in the fourth groove 274.

[0094] It is understandable that the two second mating parts are the third sliding shaft and the fourth sliding shaft, and the bracket is provided with the corresponding third sliding groove and the fourth sliding groove.

[0095] This embodiment employs a first sliding shaft and a first sliding groove, a second sliding shaft and a second sliding groove, a third sliding shaft and a third sliding groove, and a fourth sliding shaft and a fourth sliding groove, using two positioning points in the F1 and F2 directions respectively. This avoids wobbling gaps between the operating lever and the lever assembly, as well as between the lever assembly and the support, thus improving the user experience. Furthermore, the operating lever can achieve a large rotation angle in both the first direction F1 and the second direction F2, with the same movement distance, making human-machine operation more convenient. Moreover, the included angle generated by the operating lever during movement and the movement trajectory of the operating lever in the first direction F1 and the second direction F2 can be adjusted according to the needs of different users, improving the human-machine operation effect.
