Technical Field

[0001] The present application relates to the field of garden tools, and in particular to a gearbox parking arm limiting structure for a lawn mowing vehicle. Background Art

[0002] Walking tools are widely used in the field of garden tools. Walking tools are equipped with a power device that can drive itself and functional components for performing specific tasks. The power device and functional components can use the same power source or different power sources according to the specific design of the product. The tasks that the functional components can perform usually include mowing, snow removal, etc.

[0003] Walking tools can be divided into two types according to the usage status: riding type and pushing type. Among them, riding tools allow users to sit or stand on the tool without having to push the tool with effort, which has good convenience. However, riding tools are usually larger in size.

[0004] Riding tools usually have a throttle, parking and brake mechanism controlled by the foot, wherein the parking mechanism usually includes a parking arm connected to a gear box. During actual operation, the parking arm is prone to shaking, resulting in abnormal noise during the operation of the machine. Summary of the invention

[0016] As an improvement of this solution, the parking arm is arranged in the middle of the mounting portion, and the first limiting portion and the second limiting portion are arranged on both sides of the parking arm.

[0017] As an improvement of the present solution, a fixing plate is further included for limiting the movement of the parking arm, the first limiting portion and the second limiting portion along a third direction; the third direction is perpendicular to the first direction and to the first plane, and the parking arm swings in the first plane.

[0018] As an improvement of this solution, the mounting portion is fixedly connected or integrally connected to the gear box.

[0034] The meaning of "inside" and "outside" in this application refers to the direction from the signal line to the inside of the working area relative to the signal line itself, and the opposite direction is outside; it is not a specific limitation on the device mechanism of this application.

[0035] The term “connection” as used in this application may mean a direct connection between components or an indirect connection between components via other components. Example

[0036] like Figure 1 The parking arm 3 of the gear box for a lawn mowing vehicle is shown. The parking arm 3 is connected to the gear box. The parking structure in the gear box is triggered by the parking arm 3. The parking arm 3 moves in a first direction to park the vehicle. In this embodiment, the first direction is the counterclockwise direction shown in the picture. The specific structure of the gear box and the parking structure in the gear box are well known in the art and will not be described in detail here.

[0037] like Figure 1-3 As shown, the gearbox is provided with a mounting portion 2 fixedly connected, the parking arm 3 is connected, and the first limit portion 6 and the second limit portion 7 are both connected to the mounting portion 2. The parking arm 3 is movably connected to the middle of the mounting portion 2, and the end of the parking arm 3 is connected to the parking structure in the gearbox, and the first limit portion 6 and the second limit portion 7 are arranged on both sides of the parking arm 3. Specifically, the first limit portion 6 and the second limit portion 7 installation places are respectively arranged on both sides of the installation position of the parking arm 3. In this embodiment, the first limit portion 6 and the second limit portion 7 installation places are both cylindrical protruding structures, and a screw hole is arranged in the middle position of the end surface, and the fixing plate 8 is fixed by screws matching the screw holes. The fixing plate 8 is used to limit the movement of the parking arm 3, the first limit portion 6 and the second limit portion 7 along the axial position of the mounting screw.

[0038] In this embodiment, the first limiter 6 and the second limiter 7 are both torsion springs, one end of which is respectively sleeved on the first limiter 6 and the second limiter 7 installation positions, and the other end is respectively against the two sides of the parking arm 3. The first limiter 6 is used to provide resistance when the parking arm 3 moves in the clockwise direction; the second limiter 7 is used to provide resistance when the parking arm 3 moves in the counterclockwise direction. With this structure, the parking arm 3 is stabilized by two torsion springs at the same time, which can effectively improve the stability of the parking arm 3 during the movement process. Further reduce the abnormal noise generated by the parking arm 3 during the movement process. Example

[0039] The difference between this embodiment and the first embodiment is that the first limiting portion 6a in this embodiment is a hard structure fixing member, which directly limits the parking arm 3 from moving in the clockwise direction. Figure 5 As shown, in this embodiment, the first limiting portion 6a is an L-shaped component bent from a metal material, one end of which is fixed to the fixing plate 8 by screws, and the other end abuts against one side of the parking arm 3 to limit the parking arm 3 from rotating in the clockwise direction.

[0040] The advantage of this improvement is that the parking arm 3 usually only needs to move in one direction to achieve the parking effect. For example, in this embodiment, the parking arm 3 moves from the middle position in the counterclockwise direction in the figure to activate the parking function. When the method of embodiment 1 is adopted, since both sides of the parking arm 3 are torsion springs, the parking arm 3 has room to swing to both sides. In this implementation, the first limiter 6a is set to a hard material, which limits the space for the parking arm 3 to swing from the middle position in the clockwise direction, reduces the overall displacement of the parking arm 3, reduces the unnecessary activity space of the parking arm 3, further improves its movement stability and reduces the possibility of abnormal noise.

[0041] It should also be noted that in both the first and second embodiments, the mounting portion 2 is disposed on the gear box. In more embodiments, the mounting portion 2 may also be integrally disposed on the gear box or detachably connected to the gear box. Based on the different connection methods between the frame and the gear box, the mounting portion 2 may also be installed in the frame or integrally formed on the frame.

[0042] The moving direction of the parking arm 3 described in the embodiment is only an example. In more implementations, the parking arm 3 may be triggered by moving in different directions.
