Description

Technical Field

[0001] This utility model relates to the field of mini tillers, specifically to a braking mechanism for a ride-on mini tiller. Background Technology

[0002] Traditional mini-tillers are mostly hand-held, which are highly adaptable to different terrains and have low cost, but require a lot of effort to operate and are less efficient. Nowadays, many ride-on mini-tillers have also emerged, which reduce the labor intensity and greatly improve efficiency.

[0003] However, mini-tillers are mostly used in small areas such as farmland, hills, and orchards. When using a ride-on mini-tiller in such narrow areas, it is easy to be restricted and difficult to turn. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a braking mechanism for a ride-on mini-tiller, so as to solve the problem that existing ride-on mini-tillers are easily restricted and difficult to turn when used in narrow areas.

[0005] To achieve the above objectives, this utility model provides a braking mechanism for a ride-on mini-tiller, which is applied to a ride-on mini-tiller and includes a first pedal, a second pedal, a first braking mechanism, and a second braking mechanism. The first pedal and the first braking mechanism are connected, and the first braking mechanism is used to stop one of the rear wheels of the ride-on mini-tiller. The second pedal and the second braking mechanism are connected, and the second braking mechanism is used to stop the other rear wheel of the ride-on mini-tiller.

[0006] The principle and beneficial effects of the technical solution are as follows: the first pedal is used to control the first braking mechanism to stop one of the rear wheels of the ride-on mini-tiller; the second pedal is used to control the second braking mechanism to stop the other rear wheel of the ride-on mini-tiller. By controlling the braking mechanisms of the two rear wheels separately through the two pedals, the two rear wheels can be stopped independently. When used in narrow areas such as farmland, hills, orchards, by stopping the rear wheel on the side to be turned, the mini-tiller can rotate around that rear wheel as a fulcrum, which greatly reduces the turning radius, thus facilitating turning in narrow areas.

[0007] In a preferred embodiment of the present invention, the first pedal and the second pedal are located on the same side of the ride-on micro-tiller.

[0008] Beneficial effect: By placing the first pedal and the second pedal on the same side, it is convenient for the user to press both pedals simultaneously with one foot tilted or placed horizontally, so as to achieve the purpose of overall braking.

[0009] In a preferred embodiment of this utility model, the first pedal is provided with a rotatable buckle, and the second pedal is provided with a fixing rod. The buckle is rotatably engaged with the fixing rod, so that the first pedal and the second pedal remain relatively fixed; or the second pedal is provided with a rotatable buckle, and the first pedal is provided with a fixing rod. The buckle is rotatably engaged with the fixing rod, so that the first pedal and the second pedal remain relatively fixed.

[0010] Beneficial effects: The buckle and the fixing rod are used to connect the first pedal and the second pedal. Their positions can be interchanged. When the user is driving on the road, the buckle can be attached to the fixing rod to keep the first pedal and the second pedal relatively fixed. At this time, pressing either pedal can achieve a complete stop. When in operation, the buckle can be opened to make the first pedal and the second pedal relatively independent, which makes it easier to stop one of the rear wheels individually and reduce the turning radius.

[0011] In a preferred embodiment of the present invention, the first braking mechanism includes a first rocker arm rotatably mounted on the chassis of the ride-on mini-tiller and a second rocker arm coaxially fixed to the first rocker arm. The first rocker arm is fixedly connected to the first pedal. The second rocker arm is provided with a rotatable first connecting rod. One end of the first connecting rod is rotatably engaged with the second rocker arm, and the other end is fixedly connected to a first brake. The first brake is disposed in one of the wheel hubs of the ride-on mini-tiller.

[0012] Beneficial effects: When the first pedal is pressed, the first rocker arm rotates clockwise by a certain angle, which drives the second rocker arm to rotate clockwise. The second rocker arm pulls the first connecting rod forward, thereby triggering the first brake and stopping one of the rear wheels of the ride-on micro-tiller. The first brake can be an existing disc brake or drum brake, and its structure is relatively existing.

[0013] In a preferred embodiment of this utility model, the second braking mechanism includes a third rocker arm rotatably mounted on the chassis of the ride-on mini-tiller and a fourth rocker arm coaxially fixed to the third rocker arm. The third rocker arm is fixedly connected to the second pedal. The fourth rocker arm is provided with a rotatable second connecting rod. One end of the second connecting rod is rotatably engaged with the fourth rocker arm, and the other end is rotatably engaged with a fifth rocker arm. A horizontal shaft is fixed on the fifth rocker arm. The horizontal shaft spans the chassis of the ride-on mini-tiller and is rotatably mounted above the chassis of the ride-on mini-tiller. A sixth rocker arm is fixed on the side of the horizontal shaft away from the fifth rocker arm. The sixth rocker arm is provided with a rotatable third connecting rod. One end of the third connecting rod is rotatably engaged with the sixth rocker arm, and the other end is fixedly connected to a second brake. The second brake is disposed in another wheel hub of the ride-on mini-tiller.

[0014] Beneficial effects: When the second pedal is pressed, the third rocker arm rotates clockwise by a certain angle, which in turn drives the coaxially fixed fourth rocker arm to rotate clockwise. The fourth rocker arm pulls the second connecting rod forward. Since the horizontal shaft is rotatably mounted above the chassis of the ride-on mini-tiller, when the second connecting rod moves forward, it drives the fifth rocker arm to rotate counterclockwise under the restriction of the horizontal shaft. The counterclockwise rotation of the fifth rocker arm causes the sixth rocker arm to rotate counterclockwise through the horizontal shaft, pulling the third connecting rod forward, thereby triggering the second brake to stop the other rear wheel of the ride-on mini-tiller. The second brake can be an existing disc brake or drum brake.

[0015] In a preferred embodiment of the present invention, the base frame of the riding micro-tiller near the first rocker arm is provided with a first pin, and the first pin is provided with a first tension spring. One end of the first tension spring is engaged with the first pin, and the other end is engaged with the second rocker arm.

[0016] Beneficial effects: The first pin is used to install the first tension spring. When the second rocker arm rotates clockwise, the first tension spring is stretched. After the first pedal is released, the second rocker arm returns to its original position under the action of the first tension spring, thereby driving the first rocker arm and the first pedal to return to their original positions.

[0017] In a preferred embodiment of the present invention, the base frame of the riding micro-tiller is provided with a second pin on the side near the sixth rocker arm, and a second tension spring is provided on the second pin. One end of the second tension spring is engaged with the second pin, and the other end is engaged with the sixth rocker arm.

[0018] Beneficial effects: The second pin is used to install the second tension spring. When the sixth rocker arm rotates clockwise, the second tension spring is stretched. After the second pedal is released, the sixth rocker arm is reset under the action of the second tension spring. The fifth rocker arm is rotated and reset through the horizontal axis. Then, the fourth rocker arm, the third rocker arm and the second pedal are reset through the second connecting rod.

[0019] In a preferred embodiment of the present invention, a differential is provided between the two rear wheels of the riding micro-tiller, and a differential lock is provided on the differential. The differential lock is connected to a seventh rocker arm, which passes through the seat of the riding micro-tiller and is located in front of the seat.

[0020] Beneficial effects: The differential is used to enable the two rear wheels to rotate at different speeds, and the differential lock is used to lock the differential, keeping the two rear wheels relatively fixed and preventing them from spinning freely; the seventh rocker arm is used to connect the differential lock, and its other end passes through the seat and is located in the front side of the seat, that is, below the driver's thigh. When spinning freely occurs, the driver can trigger the seventh rocker arm with his heel, thereby opening the differential lock and achieving a quick locking effect. Attached Figure Description

[0032] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] Example 1 As attached Figure 1 , Figure 2 and Figure 4 As shown, this utility model provides a braking mechanism for a ride-on mini-tiller: applied to a ride-on mini-tiller 1, including a first pedal 2, a second pedal 3, a first braking mechanism 4, and a second braking mechanism 5. The first pedal 2 and the first braking mechanism 4 are connected, and the first braking mechanism 4 is used to stop one of the rear wheels of the ride-on mini-tiller 1. The second pedal 3 and the second braking mechanism 5 are connected, and the second braking mechanism 5 is used to stop the other rear wheel of the ride-on mini-tiller 1. By controlling the braking mechanisms of the two rear wheels separately through the two pedals, the two rear wheels can be stopped independently. When used in narrow areas such as farmland, hills, orchards, by stopping the rear wheel on the side to be turned, the mini-tiller can rotate around that rear wheel as a fulcrum, greatly reducing the turning radius and facilitating turning in narrow areas.

[0034] As attached Figure 2As shown, in this embodiment, the first braking mechanism 4 includes a first rocker arm 41 rotatably mounted on the chassis of the ride-on mini-tiller 1 and a second rocker arm 42 coaxially fixed with the first rocker arm 41. The first rocker arm 41 is fixedly connected to the first pedal 2. The second rocker arm 42 is provided with a rotatable first connecting rod 43. One end of the first connecting rod 43 is rotatably engaged with the second rocker arm 42, and the other end is fixedly connected to a first brake 44. The first brake 44 is disposed in one of the wheel hubs of the ride-on mini-tiller 1. The first brake 44 can be an existing disc brake or drum brake, and its structure is relatively existing. When the first pedal 2 is pressed, the first rocker arm 41 rotates clockwise by a certain angle, driving the second rocker arm 42 to rotate clockwise. The second rocker arm 42 pulls the first connecting rod 43 forward, thereby triggering the first brake 44 and stopping one of the rear wheels of the ride-on mini-tiller 1.

[0035] As attached Figure 2 As shown, in this embodiment, the base frame of the riding micro-tiller 1 near the first rocker arm 41 is provided with a first pin 45, and a first tension spring 46 is provided on the first pin 45. One end of the first tension spring 46 is engaged with the first pin 45, and the other end is engaged with the second rocker arm 42. The first pin 45 is used to install the first tension spring 46. Both ends of the first tension spring 46 have hook-shaped structures, which respectively pull the second rocker arm 42 and the first pin 45. When the second rocker arm 42 rotates clockwise, the first tension spring 46 is stretched. After the first pedal 2 is released, the second rocker arm 42 returns to its original position under the action of the first tension spring 46, which in turn drives the first rocker arm 41 and the first pedal 2 to return to their original positions.

[0036] As attached Figure 4 and Figure 5As shown, in this embodiment, the second braking mechanism 5 includes a third rocker arm 51 rotatably mounted on the chassis of the ride-on mini-tiller 1 and a fourth rocker arm 52 coaxially fixed to the third rocker arm 51. The third rocker arm 51 is fixedly connected to the second pedal 3. The fourth rocker arm 52 is provided with a rotatable second connecting rod 53. One end of the second connecting rod 53 is rotatably engaged with the fourth rocker arm 52, and the other end is rotatably engaged with a fifth rocker arm 54. A horizontal shaft 55 is fixed on the fifth rocker arm 54. The horizontal shaft 55 spans the chassis of the ride-on mini-tiller 1 and is rotatably mounted above the chassis of the ride-on mini-tiller 1. A sixth rocker arm 56 is fixed on the side of the horizontal shaft 55 away from the fifth rocker arm 54. The sixth rocker arm 56 is provided with a rotatable third connecting rod 57. One end of the third connecting rod 57 is rotatably engaged with the sixth rocker arm 56, and the other end is fixedly connected to... A second brake 58 is provided, which is located in the other wheel hub of the ride-on mini-tiller 1. The second brake 58 is the same as the first brake 44 and can be an existing disc brake or drum brake. When the second pedal 3 is pressed, the third rocker arm 51 rotates clockwise by a certain angle, which drives the coaxially fixed fourth rocker arm 52 to rotate clockwise. The fourth rocker arm 52 pulls the second connecting rod 53 forward. Since the horizontal shaft 55 is rotatably mounted above the chassis of the ride-on mini-tiller 1, when the second connecting rod 53 moves forward, under the restriction of the horizontal shaft 55, it drives the fifth rocker arm 54 to rotate counterclockwise. The counterclockwise rotation of the fifth rocker arm 54 causes the sixth rocker arm 56 to rotate counterclockwise through the horizontal shaft 55, which pulls the third connecting rod 57 forward, thereby triggering the second brake 58 and stopping the other rear wheel of the ride-on mini-tiller 1.

[0037] As attached Figure 5 As shown, in this embodiment, the base frame of the riding micro-tiller 1 near the sixth rocker arm 56 is provided with a second pin 59, and a second tension spring 510 is provided on the second pin 59. One end of the second tension spring 510 is engaged with the second pin 59, and the other end is engaged with the sixth rocker arm 56. The second pin 59 is used to install the second tension spring 510. When the sixth rocker arm 56 rotates clockwise, the second tension spring 510 is stretched. After the second pedal 3 is released, the sixth rocker arm 56 is reset under the action of the second tension spring 510. The fifth rocker arm 54 is rotated and reset through the horizontal shaft 55, and then the fourth rocker arm 52, the third rocker arm 51 and the second pedal 3 are reset through the second connecting rod 53.

[0038] As attached Figure 2 and Figure 3As shown, in this embodiment, the first pedal 2 and the second pedal 3 are located on the same side of the riding-type micro-tiller 1. The first pedal 2 is provided with a rotatable buckle 6, and the second pedal 3 is provided with a fixing rod 7. The buckle 6 is rotatably engaged with the fixing rod 7, so that the first pedal 2 and the second pedal 3 remain relatively fixed. Specifically, the buckle 6 has a circular slot and is rotatably engaged with the fixing rod 7. The fixing rod 7 can be a semi-threaded bolt, which can be quickly installed onto the second pedal 3 through threads. Its smooth cylindrical part cooperates with the buckle 6 to form a snap-fit. The bolt head restricts the buckle 6 so that it will not fall off. When either pedal is stepped on, both pedals can be stepped on simultaneously to achieve the effect of stopping the whole machine. When working, the buckle 6 is opened, so that the first pedal 2 and the second pedal 3 are relatively independent, which makes it easier to stop one of the rear wheels individually and reduce the turning radius.

[0039] Example 2 As attached Figure 1 and Figure 6 As shown, based on Embodiment 1, the braking mechanism of the riding micro-tiller of this utility model further includes a differential 8 disposed between the two rear wheels of the riding micro-tiller 1. The differential 8 is provided with a differential lock 9. Both the differential 8 and the differential lock 9 are relatively existing technologies. The differential lock 9 is connected to a seventh rocker arm 10. The seventh rocker arm 10 is used to connect the differential lock 9. Its other end passes through the seat and is located in the front side of the seat, that is, under the driver's thigh. When freewheeling occurs, the driver can trigger the seventh rocker arm 10 with his heel, thereby opening the differential lock 9 and achieving a quick locking effect.
