Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a gear shifting component of a lawnmower control structure. Background Technology

[0002] A lawnmower is a device used for trimming lawns, vegetation, etc. It can move forward or backward during the trimming process to meet the needs of moving the trimming area. The operator only needs to control the direction and speed, making it very convenient to use and with broad application prospects.

[0003] Currently, existing lawnmowers on the market, such as the control components, gearbox, and lawnmower disclosed in patent application CN118896158A, have a first rotating component, a first motion switching component, and a second motion switching component. Both the first and second motion switching components are connected to the first rotating component and can convert the rotational motion of the first rotating component into linear motion. The first motion switching component drives the gear shifting component to achieve gear shifting, and the second motion switching component drives the transmission component to achieve speed adjustment. Furthermore, the first rotating component is connected to the second motion switching component via a connecting rod for transmission. The second motion switching component or the first rotating component is connected to a control handle or pedal via a lever or similar structure. When the control handle or pedal is operated, the second motion switching component is rotated, converting its rotational motion into linear motion for speed adjustment. Simultaneously, the lever drives the first rotating component to rotate, causing the first motion switching component connected to the first rotating component to convert its rotational motion into linear motion for gear shifting, thus achieving coordinated control of speed adjustment and gear shifting. Furthermore, its shifting assembly includes a movable component sleeved on a first drive shaft. The first drive shaft is connected to the movable component via a spline. The first drive shaft and the movable component achieve circumferential limiting and meet the requirements for axial sliding, thereby enabling the movable component to drive the first drive shaft to rotate. Additionally, a first transmission component and a second transmission component, which are subject to power input, are rotatably mounted on the first drive shaft. A clearance is provided between the first and second transmission components for the movable component to move. Positioning pins are provided on the first and second transmission components, and positioning holes that mate with the positioning pins are provided on the movable component. Additionally, a drive connector is connected to the moving part, and the drive connector includes a fixed frame and an intermediate shaft. The fixed frame is located on one side of the moving part, and the intermediate shaft is fixedly connected to the fixed frame. A swing ring is rotatably mounted on the intermediate shaft via a rotating sleeve. Swing columns are provided on both sides of the swing ring, respectively abutting against both sides of the moving shaft. One swing column is also connected to a first motion switching component. That is, when the first motion switching component moves linearly, it drives the swing column to swing around the intermediate shaft, thereby driving the moving part to move axially along the first transmission shaft. Through the connection between the moving part and the first or second transmission component, rotation in different directions is achieved, thus causing the first transmission shaft to rotate in different directions to meet the shifting requirements. Although the above structure can meet the shifting requirements, it still requires multiple structures such as the moving part and the drive connector for connection, making the structure relatively complex. Furthermore, it requires a sufficiently large space to install and accommodate the deflection of the drive connector, resulting in significant space waste. Utility Model Content

[0013] The aforementioned gear shifting component of a lawnmower control structure includes a linkage component comprising a connecting end and a limiting end. The connecting end is sleeved on the connecting component and moves linearly with the connecting component. The limiting end abuts against the connecting component to restrict the connecting end from rotating circumferentially on the connecting component. Meanwhile, a latch is provided on the linkage component, and one end of the unlocking connecting arm extends into the latch.

[0014] In the aforementioned gear shifting assembly of a lawnmower control structure, one end of the unlocking control member is provided with a connector, the connector is provided with a circumferential limiting surface, and the other end of the unlocking connecting arm is provided with a sleeve hole fitted onto the connector, and the sleeve hole is provided with a circumferential contact surface corresponding to the circumferential limiting surface, so as to restrict the circumferential movement of the unlocking connecting arm relative to the unlocking control member.

[0027] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following embodiments are provided in conjunction with the appendix. Figure 1 To be continued Figure 8 The technical solution provided by this utility model is described in detail, but the following content is not intended to limit this utility model.

[0028] Figure 1 This is a structural diagram of a lawnmower control structure according to the present invention. Figure 1As shown, the lawnmower control structure provided in this embodiment includes: a gear shifter 1, a gear shifter 2, a cooperating rotating component 3, and a connecting component 4. The gear shifter 1 converts the input rotational motion into linear motion to drive the gear shifting assembly and achieve gear change, meeting the gear adjustment requirements. Simultaneously, the gear shifter 2 converts the input rotational motion into linear motion to drive the gear shifting assembly 6 and achieve gear switching, meeting the gear shifting requirements and enabling the vehicle to move forward or backward. Furthermore, the cooperating rotating component 3 is positioned between the gear shifter 1 and the gear shifter 2 and rotates, making the cooperating rotating component 3 a linkage structure between the gear shifter 1 and the gear shifter 2, realizing the linkage between gear shifting and gear change operations, facilitating vehicle control. Meanwhile, a connecting member 4 is provided between the mating rotating member 3 and the speed switching member 1, so that when the mating rotating member 3 rotates, the speed switching member 1 can be pushed and pulled through the connecting member 4 to realize the rotational movement of the speed switching member 1, or when the speed switching member 1 rotates, the mating rotating member 3 can be pushed and pulled through the connecting member 4 to realize the rotational movement of the mating rotating member 3. In practice, the choice between the mating rotating member 3 driving the speed switching member 1 or the speed switching member 1 driving the mating rotating member 3 can be reasonably selected according to actual needs. Furthermore, when the rotating component 3 rotates, both the gear shifting component 1 and the gear shifting component 2 rotate, realizing the linkage operation of gear shifting and gear changing. Just like the first rotating component, the first motion switching component, and the second motion switching component in the control components, gearbox, and lawnmower disclosed in patent application CN118896158A, the first motion switching component has the same or similar structure as the gear shifting component 2 in this embodiment, the second motion switching component has the same or similar structure as the gear shifting component 1 in this embodiment, the first rotating component has the same or similar structure as the rotating component 3 in this embodiment, and the connecting rod has the same or similar structure as the connecting component 4 in this embodiment. Therefore, the structure and the way they cooperate of the gear shifting component 1, the gear shifting component 2, the rotating component 3, and the connecting component 4 will not be described in detail here.

[0029] Figure 2 This is a structural diagram of a self-locking drive component according to a preferred embodiment of the present invention. Figure 1 and Figure 2As shown, a self-locking drive component 5 is also connected to the connecting part 4. The self-locking drive component 5 acts on the output drive shaft 61 of the shift assembly 6, so that when the gear shifting and gear changing operations are linked, the self-locking drive component 5 can be driven synchronously through the connecting part 4, providing the condition for the output drive shaft to self-lock when the gear is in neutral. At this time, the self-locking drive component 5 includes a locking component 51 and an unlocking drive component 52. The locking component 51 is installed on the output drive shaft 61 of the shift assembly 6 to lock the output drive shaft 61 when the shift assembly 6 is in neutral. That is, in the neutral state, the output drive shaft 61 can be locked by the locking component 51, thereby avoiding the safety hazards caused by the vehicle continuing to move forward or backward under the action of inertia and other factors, which is beneficial to driving. After the gear shift is completed, the locking component 51 automatically releases the output drive shaft 61, so that the output drive shaft 61 can smoothly output power to meet the vehicle's operating needs under normal conditions. In addition, the unlocking drive component 52 is installed on the locking component 51 and the connecting member 4. The movement of the connecting member 4 is transmitted to the locking component 51 through the unlocking drive component, thereby locking or unlocking the locking component 51. That is, when shifting gears, the movement of the connecting member 4 can be transmitted to the locking component 51 through the unlocking drive component, thereby unlocking or locking the locking component 51. This realizes the linkage operation between neutral self-locking and shifting gears, eliminating the need for separate specific operations, simplifying the operation process, making vehicle control more convenient, and facilitating vehicle driving.

[0030] Specifically, when the gear shifter 1 and the gear shifter 2 are linked, the connecting piece 4 will move. When the connecting piece 4 moves, the locking component 51 will be in three states: a first unlocking state, a locking state, and a second unlocking state. The locking state corresponds to the neutral position of the gear shifter 6, while the first unlocking state and the second unlocking state correspond to the forward and reverse gears of the gear shifter 6, respectively.

[0031] More specifically, the locking component 51 is unlocked when the shift component 6 is in forward gear. At this time, the locking component 51 unlocks the output drive shaft 61 of the shift component 6, allowing the output shaft to rotate in the forward direction, thereby outputting forward power through the output drive shaft 61 and driving the vehicle to move forward.

[0032] In addition, the locking state of the locking component 51 is when the shift component 6 is in neutral. At this time, the locking component 51 can lock the output drive shaft 61 of the shift component 6, so that the output drive shaft 61 cannot rotate, thereby restricting the movement of the vehicle and avoiding the problem that the vehicle will continue to move under the influence of inertia and other factors, reducing the risk of loss of driving control and providing higher safety assurance.

[0033] Furthermore, the second unlocking state of the locking component 51 is when the shift component 6 is in reverse gear. At this time, the locking component 51 unlocks the output drive shaft 61 of the shift component 6, so that the output drive shaft 61 can rotate in the opposite direction, thereby outputting reverse power through the output drive shaft 61 to drive the vehicle to move backward.

[0034] Figure 3 This is a structural diagram of a locking assembly according to a preferred embodiment of the present invention. Figure 2 and Figure 3 As shown, the locking assembly 51 for unlocking and locking the output drive shaft 61 of the shift assembly 6 further includes: a locking mounting base 511, a first locking member 512, a second locking member 513, and an elastic power member 514. Preferably, the locking mounting base 511 is sleeved around the output drive shaft 61 and fixed to the machine housing. In this case, a gap is provided between the output drive shaft 61 and the locking mounting base 511, which prevents the installation of the locking mounting base 511 from interfering with the rotation of the output drive shaft 61. Additionally, it ensures that the locking mounting base 511 can approach the output drive shaft 61 as closely as possible and provides conditions for ensuring that the output drive shaft 61 is subjected to uniform force during locking.

[0035] More specifically, the first locking member 512 is mounted on the locking mounting base 511 and located on one side of the output drive shaft 61. At this time, the locking mounting base 511 serves as the carrier for the first locking member 512 to be mounted on one side of the output drive shaft 61. Furthermore, the first locking member 512 moves closer to or away from the output drive shaft 61. When the first locking member 512 approaches and presses against the output drive shaft 61, it restricts the rotation of the output drive shaft 61, thus providing the conditions for locking the output drive shaft 61.

[0036] Simultaneously, the second locking member 513 is installed on the locking mounting base 511 and located on the other side of the output drive shaft 61. In this case, the locking mounting base 511 also serves as a carrier for the second locking member 513 to be installed beside the output drive shaft 61. This achieves the first locking member 512 and the second locking member 513 being located on opposite sides of the output drive shaft 61. Preferably, the first locking member 512 and the second locking member 513 are symmetrically arranged about the output drive shaft 61. Furthermore, the second locking member 513 moves closer to or away from the output drive shaft 61. When the first locking member 512 approaches and presses against the output drive shaft 61, it also restricts the rotation of the output drive shaft 61, providing the conditions for locking the output drive shaft 61. In addition, the cooperation of the first locking member 512 and the second locking member 513 achieves clamping of the output drive shaft 61, ensuring uniform force on the output drive shaft 61 during locking and enhancing the locking effect.

[0037] In addition, an elastic power member 514 is disposed between the first locking member 512 and the second locking member 513, and the elastic power member 514 can pull the first locking member 512 and the second locking member 513 closer to the output drive shaft 61. The elastic power member 514 includes, but is not limited to, a tension spring. That is, without the action of external force, the elastic power member 514 can pull the first locking member 512 and the second locking member 513 closer to each other, thereby clamping the output drive shaft 61 located between the first locking member 512 and the second locking member 513, thereby locking the output drive shaft 61 so that the output drive shaft 61 no longer rotates.

[0038] Figure 4 This is a structural diagram of the unlocking driver component 52 according to a preferred embodiment of the present invention. Figure 2 and Figure 4 As shown, the unlocking drive assembly 52 for unlocking the locking assembly 51 includes: a linkage 521, an unlocking control 522, and an unlocking connecting arm 523. The linkage 521 and the unlocking connecting arm 523 transmit the movement of the connecting member 4 to the unlocking control 522, and the unlocking control 522 unlocks the locking assembly 51.

[0039] More specifically, the linkage 521 is fixedly installed on the connector 4, so that the linkage 521 can move with the connector 4, providing a structural basis for the linkage of the self-locking drive 5 in the subsequent linkage of gear shifting and shifting operations.

[0040] More specifically, the unlocking control element 522 is positioned between the first locking element 512 and the second locking element 513, allowing the unlocking control element 522 to simultaneously drive the first locking element 512 and the second locking element 513 to move and unlock. During operation, the unlocking control element 522 drives the first locking element 512 and the second locking element 513 to move away from the output drive shaft 61, thus removing the restriction of the first locking element 512 and the second locking element 513 on the output drive shaft 61 of the shift assembly 6. This allows the output drive shaft 61 of the shift assembly 6 to maintain rotation, thereby outputting forward or reverse power to meet the vehicle's forward or reverse driving needs.

[0041] More specifically, one end of the unlocking connecting arm 523 is connected to the linkage member 521, and the other end of the unlocking connecting arm 523 is connected to the unlocking control member 522. This makes the unlocking connecting arm 523 an intermediate transmission structure between the linkage member 521 and the unlocking control member 522, so that the movement of the connecting member 4 can be smoothly transmitted to the unlocking control member 522. The unlocking control member 522 unlocks the output transmission shaft 61 of the shift assembly 6. Since the connecting member 4 is an intermediate transmission structure for the linkage of gear shifting and gear changing operations, the linkage of the self-locking drive member 5 can be realized simultaneously during the linkage of gear shifting and gear changing. Therefore, there is no need to operate the self-locking drive member 5 separately, making the operation more convenient and beneficial to the driving of the vehicle.

[0042] In a preferred embodiment, the first locking member 512 and the second locking member 513 used to clamp the output drive shaft 61 of the shift assembly 6 are both configured as arc-shaped structures, and their arc-shaped contours can adapt to the outer contour of the output drive shaft 61, so that the first locking member 512 and the second locking member 513 can fit the output drive shaft 61 more closely, thereby improving the effect of locking the output drive shaft 61. Furthermore, when the first locking member 512 and the second locking member 513 are assembled onto the locking mounting base 511, one end of each of the first locking member 512 and the second locking member 513 is hinged to the locking mounting base 511, while the other end of each of the first locking member 512 and the second locking member 513 is connected to the elastic power member 514. Preferably, the lower ends of the first locking member 512 and the second locking member 513 are hinged to the locking mounting base 511, while the upper ends of the first locking member 512 and the second locking member 513 are respectively connected to both ends of the elastic power member 514. This ensures that the installation and operation of the elastic power member 514 are not interfered with by the output drive shaft 61, and also further ensures that the output drive shaft 61 can maintain uniform force when the first locking member 512 and the second locking member 513 clamp the output drive shaft 61.

[0043] Figure 5 This is a schematic diagram of the installation of the unlocking control component between the first locking component and the second locking component according to a preferred embodiment of the present invention; Figure 6 This is a structural diagram of an unlocking control component according to a preferred embodiment of the present invention. Figures 2 to 5As shown, in order to achieve the cooperation between the unlocking control member 522, the first locking member 512, and the second locking member 513, a first trigger part 5121 is also provided on the end of the first locking member 512 and the second locking member 513 connected to the elastic power member 514. The two first trigger parts 5121 are arranged opposite to each other, and the unlocking control member 522 is placed between the two first trigger parts 5121. When the unlocking control member 522 is activated, it can act on the two first trigger parts 5121 at the same time, and push the two first trigger parts 5121 to move in opposite directions. That is, when the unlocking control member 522 is activated, it can push the first locking member 512 and the second locking member 513 at the same time, and make them move towards the opposite side. This allows the first locking member 512 and the second locking member 513 to move away from the output drive shaft 61, and no longer restrict the rotation of the output drive shaft 61, thereby unlocking the output drive shaft 61.

[0044] More specifically, a first trigger surface 5122 is provided on each of the two first trigger parts 5121 on opposite sides. Simultaneously, an unlocking control member 522 is rotatably mounted between the two first trigger parts 5121. It is worth noting that the unlocking control member 522 is rotatably mounted on the machine housing of the device to ensure stable installation and maintain its position between the first locking member 512 and the second locking member 513. Furthermore, the unlocking control member 522, located between the two first trigger parts 5121, is provided with two first contact surfaces 5221, two second contact surfaces 5222, and four intermediate transition surfaces 5223. The two first contact surfaces 5221 are arranged opposite each other, as are the two second contact surfaces 5222. The four intermediate transition surfaces 5223 are divided into two groups, with the two intermediate transition surfaces 5223 in each group also arranged opposite each other. A [missing information - likely a type of interlocking surface] is provided between each first contact surface 5221 and each second contact surface 5222. Preferably, the two first contact surfaces 5221, the two second contact surfaces 5222, and the four intermediate transition surfaces 5223 are distributed on the four sides of the rectangle and at the four vertices of the sides. Furthermore, the distance between the two first contact surfaces 5221 is equal to the distance between the two second contact surfaces 5222 and is less than the distance between the two intermediate transition surfaces 5223 in the same group, so that the rectangle in which the two first contact surfaces 5221, the two second contact surfaces 5222, and the four intermediate transition surfaces 5223 are distributed is a square. Furthermore, during use, the first trigger surface 5122 abuts against any one of the first contact surface 5221, the second contact surface 5222, and the intermediate transition surface 5223. The limiting method includes, but is not limited to, the following: when the shift assembly 6 is in forward gear, the two first trigger surfaces 5122 abut against one of the two intermediate transition surfaces 5223 arranged opposite to each other. Since the distance between the two intermediate transition surfaces 5223 in the same group is large, the two first trigger surfaces 5122 will be pushed towards the opposite side, thereby opening the elastic power member 514, so that the first locking member 512 and the second locking member 513 are both away from the output drive shaft 61, thereby unlocking the output drive shaft 61 and meeting the needs of the vehicle to move forward. When a gear shift is required, the forward gear will first switch to neutral. At this time, the unlocking control 522 rotates by a predetermined angle, so that the two first trigger surfaces 5122 abut against the two first contact surfaces 5221 or the two second contact surfaces 5222 respectively. Since the distance between the two first contact surfaces 5221 or the two second contact surfaces 5222 is smaller than the distance between the two opposite intermediate transition surfaces 5223, the pushing effect of the two first contact surfaces 5221 or the two second contact surfaces 5222 on the two first trigger surfaces 5122 is weakened or eliminated. This allows the first locking member 512 and the second locking member 513 to reset under the action of the elastic power member 514, thereby clamping the output drive shaft 61 and meeting the usage requirements of locking the output drive shaft 61 in neutral.When the shift assembly 6 continues to shift from neutral to reverse, the unlocking control member 522 continues to rotate by a predetermined angle, causing the two first trigger surfaces 5122 to abut against another set of oppositely arranged intermediate transition surfaces 5223. The two opposite intermediate transition surfaces 5223 then push the two first trigger surfaces 5122 toward the opposite side, causing the elastic power member 514 to open again. This again moves the first locking member 512 and the second locking member 513 away from the output drive shaft 61, thus unlocking the output drive shaft 61 and satisfying the vehicle's reverse movement requirement. Since the reverse operation will achieve unlocking, locking, and re-unlocking in the same way, the specific method of the reverse operation will not be described here.

[0045] More specifically, the linkage 521 used to transmit the movement of the connector 4 to the unlocking connecting arm 523 includes a connecting end 5211 and a limiting end 5212. During assembly, the connecting end 5211 is sleeved on the connector 4 and moves linearly with the connector 4. The connecting end 5211 achieves stable installation on the connector 4 and limits the linear movement of the connector 4. At the same time, the limiting end 5212 abuts against the connector 4 to restrict the circumferential rotation of the connecting end 5211 on the connector 4. The limiting end 5212 further improves the stability and reliability of the position of the linkage 521 after installation on the connector 4, providing conditions for accurately transmitting the movement of the connector 4 to the unlocking connecting arm 523. Meanwhile, a slot 5213 is provided on the linkage 521, and one end of the unlocking connecting arm 523 extends into the slot 5213. Preferably, the linkage 521 is a sheet structure and the wall thickness of the slot 5213 is relatively thin. At this time, a small gap is provided between the unlocking connecting arm 523 and the side wall of the slot 5213 to meet the usage requirements of the unlocking connecting arm 523 swinging in the slot 5213. That is, when the linkage 521 moves with the connecting member 4, since the other end of the unlocking connecting arm 523 is connected to the rotating unlocking control member 522, the linkage 521 can drive the unlocking connecting arm 523 to rotate around the unlocking control member 522, thereby driving the control member to rotate and realize the locking and unlocking of the first locking member 512 and the second locking member 513.

[0046] More specifically, a connector 5224 is provided at one end of the unlocking control component 522. Preferably, the connector 5224 and the unlocking control component 522 are an integral structure, which can be regarded as the end of the unlocking control component 522 being machined, so that the connector 5224 has higher structural strength. At this time, a circumferential limiting surface 5225 is provided on the connector 5224, and a sleeve hole 5231 is provided on the other end of the unlocking connecting arm 523, which is fitted onto the connector 5224. A circumferential contact surface 5232 corresponding to the circumferential limiting surface 5225 is provided in the sleeve hole 5231. This allows the circumferential movement of the unlocking connecting arm 523 relative to the unlocking control member 522 to be restricted by the cooperation of the circumferential limiting surface 5225 and the circumferential contact surface 5232 when the sleeve hole 5231 of the unlocking connecting arm 523 is fitted onto the connector 5224 of the unlocking control member 522, thus ensuring that the unlocking connecting arm 523 can reliably push the unlocking control member 522 to rotate.

[0047] As a further preferred embodiment, brake pads 524 are also provided on the side of the first locking member 512 and the second locking member 513 near the output drive shaft 61, so that the braking of the output drive shaft 61 by the first locking member 512 and the second locking member 513 is achieved by the brake pads 524, which increases friction, improves the braking effect, and also facilitates replacement after wear and tear.

[0048] As a further preferred embodiment, a brake disc 62 is also fitted onto the output drive shaft 61, and the brake disc 62 is circumferentially limited to the output drive shaft 61. Preferably, the brake disc 62 and the output drive shaft 61 are connected by a spline, which provides a better circumferential limiting effect. Furthermore, the first locking member 512 and the second locking member 513 are respectively disposed on both sides of the brake disc 62, so that the first locking member 512 and the second locking member 513 can directly lock the output drive shaft 61 through contact with the brake disc 62, increasing the lever arm during locking, resulting in more timely braking and a better effect.

[0049] in addition, Figure 7 This is a structural diagram of a gear shifting assembly according to a preferred embodiment of the present invention; Figure 8 This is a structural diagram of a preferred embodiment of the mating component of the present invention. (See diagram below.) Figure 1 , Figure 7 as well as Figure 8As shown, the shifting assembly 6 of the lawnmower control structure provided in this embodiment also includes an input component 63, a forward transmission component 64, a reverse transmission component 65, and a selection mating component 66. At this time, the input component 63 is connected to the transmission assembly, allowing the power energy after the transmission assembly changes gears to be transmitted to the input component 63. Simultaneously, both the forward transmission component 64 and the reverse transmission component 65 are rotatably mounted on the output drive shaft 61. It is worth noting that the forward transmission component 64 and the reverse transmission component 65 only use the output drive shaft 61 as their rotation axis, so that the output drive shaft 61 only serves as a support structure for the forward transmission component 64 and the reverse transmission component 65, and the rotation of the forward transmission component 64 and the reverse transmission component 65 does not interfere with the rotation of the output drive shaft 61. Furthermore, the input component 63 is rotatably mounted between the forward transmission component 64 and the reverse transmission component 65. Preferably, the input component 63 is rotatably mounted on the machine housing of the device, achieving stable installation of the input component 63. Furthermore, the input component 63 is simultaneously connected to both the forward transmission component 64 and the reverse transmission component 65, driving them to rotate in opposite directions, thus providing the conditions for subsequent output of two completely opposite forces. Meanwhile, a selection engagement component 66 is positioned between the forward transmission component 64 and the reverse transmission component 65 and selectively connects to either the forward or reverse transmission component 65. That is, when the selection engagement component 66 is selectively connected to the forward transmission component 64, the forward transmission component 64 drives the selection engagement component 66 to rotate in the forward direction; conversely, the reverse transmission component 65 drives the selection engagement component 66 to rotate in the reverse direction. Additionally, the selection engagement component 66 is also connected to the gear shifting component 2, meaning that the linear motion of the gear shifting component 2 drives the selection engagement component 66 to move between the forward and reverse transmission components 64 and 65, ensuring that the selection engagement component 66 can selectively connect to either the forward or reverse transmission component 64. Furthermore, the selective mating component 66 is connected to the output drive shaft 61 to drive the output drive shaft 61 to rotate. This allows the output drive shaft 61 to rotate synchronously with the selective mating component 66 when the forward transmission component 64 or the reverse transmission component 65 drives the selective mating component 66 to rotate in either direction, thereby outputting forward or reverse power to meet the vehicle's forward or reverse driving requirements.

[0050] More specifically, the selection mating part 66 for selectively connecting the forward transmission member 64 or the reverse transmission member 65 includes a selection disk 661 and a shift fork 662. In this case, the selection disk 661 is sleeved on the output drive shaft 61, and the selection disk 661 reciprocates along the axial direction of the output drive shaft 61, ensuring that the selection disk 661 can connect with the forward transmission member 64 or the reverse transmission member 65 on the output drive shaft 61 when moving along the axial direction of the output drive shaft 61. Furthermore, the selection disk 661 and the output drive shaft 61 are mutually circumferentially limited, ensuring that the selection disk 661 can drive the output drive shaft 61 to rotate. In addition, a first mating part 6611 is provided on both sides of the selection disk 661. At the same time, a second mating part 641 corresponding to the first mating part 6611 is provided on the side of the forward transmission member 64 and the reverse transmission member 65 near the selection disk 661. This allows the selection disk 661 and the forward transmission member 64, as well as the selection disk 661 and the reverse transmission member 65, to be connected through the corresponding first mating part 6611 and second mating part 641. Preferably, the first mating part 6611 and the second mating part 641 are both meshing teeth, and power transmission is achieved through the mutual meshing of the meshing teeth. Furthermore, one end of the shift fork 662 is connected to the selection disk 661. Preferably, a groove is provided on the outer wall of the selection disk 661, and one end of the shift fork 662 extends into the groove. The selection disk 661 is moved axially along the output drive shaft 61 by the push of the shift fork 662 against the groove wall. A gap is provided between the shift fork 662 and the bottom of the groove so that the shift fork 662 does not restrict the rotation of the selection disk 661. In addition, the other end of the shift fork 662 is connected to the gear shifting member 2, and the linear motion direction of the gear shifting member 2 is consistent with the axial direction of the output drive shaft 61. When the gear shifting member 2 converts the rotational motion into linear motion, it can pull the shift fork 662 to move axially along the output drive shaft 61, thereby driving the selection disk 661 to move axially along the output drive shaft 61, satisfying the use requirement of selectively connecting the selection disk 661 to the forward transmission member 64 or the reverse transmission member 65.

[0051] More specifically, the forward transmission component 64, the reverse transmission component 65, and the input component 63 are all gear drives to ensure reliable and stable power transmission. Preferably, the input component 63 is a bevel gear, and the forward transmission component 64 and the reverse transmission component 65 mesh with the input component 63 simultaneously from both sides, achieving bevel gear transmission between the input component 63 and the forward transmission component 64, as well as between the input component 63 and the reverse transmission component 65. This allows for adjustment of the power transmission direction, facilitating a more rational spatial arrangement of the structure. It also ensures that when the input component 63 rotates, the rotation directions of the forward transmission component 64 and the reverse transmission component 65 are exactly opposite, providing the conditions for subsequent output of forward and reverse power.

[0052] In addition, the selector disk 661 and the output drive shaft 61 are connected by a spline. Furthermore, the length of the spline on the output drive shaft 61 is set to be longer than the length of the spline on the selector disk 661. The spline achieves stable circumferential limiting between the selector disk 661 and the output drive shaft 61, ensuring reliable power transmission. At the same time, it also allows the longer spline on the output drive shaft 61 to adapt to the usage requirements of the selector disk 661 moving along the axial direction of the output drive shaft 61, making the structural design more reasonable.

[0053] More specifically, an active drive component 7 is connected to both the gear shifting component 1 and the cooperating rotating component 3. At this time, the active drive component 7 inputs force to both the gear shifting component 1 and the cooperating rotating component 3, so that both the gear shifting component 1 and the cooperating rotating component 3 can actively rotate. This can more reliably realize the rotation of the gear shifting component 1 and the cooperating rotating component 3, and at the same time reliably realize the movement of the gear shifting component 2 and the self-locking drive component 5. This ensures that the operator can reliably perform gear shifting, gear changing and neutral self-locking operations through the active drive component 7, realizing the linkage of gear shifting, gear changing and neutral self-locking, making the operation more convenient.

[0054] More specifically, both the connector 4 and the active drive component 7 are push-pull rods, allowing them to meet both forward and backward pulling requirements, better adapting to the changing states of the gear shifter 1, the cooperating rotating component 3, and the self-locking drive component 5. Furthermore, the push-pull rods can be connected to pedals or handles for easier operation by the operator.

[0055] The shifting assembly of the lawnmower control structure provided in this embodiment includes a gear shifting component 1, a shifting component 2, a cooperating rotating component 3, a connecting component 4, an output drive shaft 61, a forward transmission component 64, a reverse transmission component 65, and a selection cooperating component 66. The forward transmission component 64 and the reverse transmission component 65 are rotatably mounted on the output drive shaft 61, with the selection cooperating component 66 positioned between them. The selection cooperating component 66 reciprocates along the axial direction of the output drive shaft 61 and is circumferentially limited by the output drive shaft 61. Furthermore, the selection cooperating component 66 directly engages with the shifting component. The gear shifting component 2 is connected, and the gear shifting component 2 drives the selection mating component 66 to move between the forward transmission component 64 and the reverse transmission component 65, so that the power of the forward transmission component 64 or the reverse transmission component 65 can be transmitted to the output transmission shaft 61 through the selection mating component 66, thereby outputting forward power or reverse power. The structure is simple, has a low failure rate, is easy to process and manufacture, and has a more compact structure. At the same time, the gear shifting component 2, the mating rotating component 3, the connecting component 4 and the gear shifting component 1 are linked, which also realizes the linkage of gear shifting and gear changing operations, making it easy to operate.

[0056] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
