Description

Technical Field

[0001] The invention belongs to the technical field of vehicles, and in particular relates to a parking device and a riding lawn mower. Background Art

[0002] Large four-wheeled garden tools such as riding lawn mowers often require a parking device to lock the vehicle when the machine stops to prevent the vehicle from sliding.

[0003] The existing parking device has many parts and a complex structure. Since the working environment of garden tools is outdoors and mostly on grass without paved roads, the machine has large vibrations during operation. The parking device with a complex structure is prone to parts fatigue and damage, affecting its functional use.

[0004] In addition, the existing parking devices are mostly locked with toothed discs or racks. These parts have small teeth, and the contact surface of the teeth is small when they are locked. When a tooth on the toothed disc or rack is damaged, resulting in missing teeth, the parking function will fail. Parts such as toothed discs and racks are more prone to wear and breakage on four-wheel garden tools with large vibrations. Moreover, traditional parking devices are all realized by pedals, which are directly locked after being stepped on, and need to be unlocked again before continuing to drive, which is troublesome to operate. Summary of the invention

[0005] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a parking device and a riding lawn mower, which have a simple structure, parts that are not easily damaged, good stability in use, are not easily triggered by misoperation, and are easy to unlock and park.

[0022] Example 1

[0023] like Figure 1 As shown, this embodiment provides a parking device, including a frame 1, and also includes a pedal mechanism and a pull rod mechanism arranged on the frame 1.

[0024] like Figure 1 and Figure 2 As shown, the pedal mechanism includes a mounting frame 3 arranged on the frame 1, a swing arm 7 rotatably connected to the mounting frame 3, and a pedal 6 mounted on the swing arm 7, and a clamping shaft 14 is mounted on the swing arm 7. Specifically, the swing arm 7 is L-shaped, and the pedal 6 and the clamping shaft 14 are respectively mounted on both ends of the L-shaped swing arm 7, and the pedal 6 can be mounted on the end of the swing arm 7 in a movable connection manner; a first pin shaft 8 is penetrated at the L-shaped corner of the swing arm 7, and the swing arm 7 is rotatably connected to the mounting frame 3 through the first pin shaft 8 located between the pedal 6 and the clamping shaft 14.

[0025] like Figure 1 and Figure 2 As shown, the swing arm 7 is connected with a cable 5 for controlling a parking element, and the parking element may be a brake mechanism, a drive wheel locking mechanism, an electromagnetic locking mechanism, etc. The cable 5 is rotatably connected to the swing arm 7 through a second pin 9, and the mounting frame 3 is provided with a first clamping groove 302 corresponding to the position of the cable 5, and the cable 5 is clamped in the first clamping groove 302. The first clamping groove 302 is used to limit the cable 5 to prevent the cable 5 from shaking or shifting during the movement of the swing arm 7.

[0026] like Figure 2 As shown, the pedal mechanism also includes a first spring 15, one end of which is connected to the clamping shaft 14, and the other end of the first spring 15 is connected to the frame 1 (the frame is not fully drawn in the accompanying drawings). The first spring 15 can give the clamping shaft 14 the potential energy to move downward, which is convenient for the clamping shaft 14 to return to its original position when the vehicle is not parked.

[0027] like Figures 1 to 3As shown, the pull rod mechanism includes an operating rod 4, a rotating plate 11 rotatably connected to the operating rod 4, and a rotating shaft 10 fixedly connected to the rotating plate 11, and a clamping plate 13 is sleeved on the rotating shaft 10. The clamping plate 13 is fixedly connected to the rotating shaft 10, and a clamping groove 1301 matching the clamping shaft 14 is provided on the clamping plate 13, so that the clamping shaft 14 is clamped in the clamping groove 1301 when the vehicle is parked, and the contact area between the two is large and not easy to be damaged.

[0028] Further, such as Figure 1 and Figure 3 As shown, the mounting frame 3 is provided with a second slot 301 and a mounting hole corresponding to the position of the rotating shaft 10, the rotating shaft 10 is clamped in the second slot 301, one end of the rotating shaft 10 is fixedly connected to the rotating plate 11, and the other end of the rotating shaft 10 passes through the mounting hole and is rotatably connected to the mounting frame 3. The second slot 301 and the mounting hole are designed to limit the rotating shaft 10 and improve the structural stability of the device.

[0029] like Figure 1 and Figure 3 As shown, the pull rod mechanism also includes a support frame 2 provided on the frame 1, the support frame 2 is provided with a limit slot 201, and the joystick 4 passes through the limit slot 201 and is movably connected to the support frame 2. In some other embodiments, the joystick 4 can also be directly movably connected to the frame 1.

[0030] like Figure 1 and Figure 3 As shown, the pull rod mechanism also includes a second spring 12, one end of the second spring 12 is connected to the joystick 4 or the rotating plate 11, and the other end of the second spring 12 is connected to the frame 1. The second spring 12 can enable the joystick 4 to have the potential energy to move upward, so as to facilitate the return of the joystick 4 in the non-parking state.

[0031] In the present embodiment, the joystick 4 is operated by a pull rod. In some other embodiments, the joystick 4 can also be operated by a button.

[0032] like Figures 5 to 9 As shown, in the parking state, the pedal 6 is stepped on and the joystick 4 is pressed downward. The pedal 6 moves from the 6A position to the 6B position, and the swing arm 7 rotates relative to the frame 1 and the mounting frame 3, driving the clamping shaft 14 to move upward, and the joystick 4 moves from the 4A position to the 4B position, so that the rotating plate 11 drives the rotating shaft 10 to rotate, and then drives the clamping plate 13 to rotate, so that the clamping shaft 14 is clamped in the clamping groove 1301, and the parking lock is realized. The contact area between the clamping shaft 14 and the clamping plate 13 is large and not easy to be damaged. Parking requires both the pedal 6 and the joystick 4 to act, so as to prevent the user from accidentally stepping on the pedal 6 or accidentally touching the joystick 4 during driving to trigger parking, and the safety is high.

[0033] In some other embodiments, when parking, the pedal 6 may be stepped on first and then the operating lever 4 may be pressed downward; or the operating lever 4 may be pressed downward first and then the pedal 6 may be stepped on, so that the clamping shaft 14 is clamped in the clamping groove 1301 to achieve parking lock.

[0034] like Figures 1 to 4 As shown, when the vehicle is not parked, the pedal 6 is lifted, and the swing arm 7 rotates accordingly, thereby driving the clamping shaft 14 to move downward, so that the clamping shaft 14 is separated from the clamping plate 13, and the cable 5 is loosened to achieve parking unlocking; or, the joystick 4 is lifted, so that the rotating plate 11 drives the rotating shaft 10 to rotate, and then drives the clamping plate 13 to rotate, so that the clamping shaft 14 is separated from the clamping plate 13, and the cable 5 is loosened to achieve parking unlocking. These two ways of parking unlocking do not require the pedal 6 and the joystick 4 to act at the same time, and the operation is simple and convenient.

[0035] In some other embodiments, when the vehicle is not parked, the pedal 6 and the joystick 4 are lifted simultaneously, the swing arm 7 rotates and drives the clamping shaft 14 to move downward, and at the same time, the rotating plate 11 drives the rotating shaft 10 to rotate, and then drives the clamping plate 13 to rotate, so that the clamping shaft 14 and the clamping plate 13 are disengaged from each other, and the cable 5 is relaxed to achieve parking unlocking.
