Description

Power cart and its controls

This creation relates to a power cart and its control device, more precisely, a control device that integrates various functional operations of the power cart for users to operate with one hand.

Power carts are often used in agriculture or engineering fields. Taking agricultural vehicles as an example, the use of power carts is nothing more than to reduce the burden on farmers and save labor and time in field work. Therefore, a drive motor is usually provided on the agricultural power cart to drive the body forward and transport the load.

At present, the conventional power carts running in the farmland and ravines are designed with two front and rear wheels. When the user operates the power cart to move forward, the user must hold the handle with both hands to maintain balance. For the function control, the user must stop traveling, and then release one of the hands on the handle to operate. As a result, the user cannot operate conveniently while traveling, and frequent parking will also affect the efficiency of the operation.

Based on the above deficiencies, the present invention provides a power cart and a control device thereof, so that the user can conveniently operate various functions when holding the handle to make the power cart travel.

Based on the above purpose, the present invention provides a control device for a power cart, which is disposed adjacent to a grip portion, wherein the control device has two operating surfaces, and one of the operating surfaces is provided with a knob, The other operation surface is provided with at least one push switch. Preferably, the above-mentioned two operation surfaces may be perpendicular to each other, so that the operation directions of the knob and the push switch are perpendicular to each other.

By effectively integrating all the operation buttons on the power cart near the grip of the control device, the user can use the thumb and index finger of one hand to operate and control the power cart while maintaining the balance of the power cart with both hands. operating element.

In addition, the shape of the grip portion can be a cylindrical handle, and the rotation axis of the knob can be parallel to the handle, or arranged coaxially with the handle.

In addition, when the power cart can also be provided with an operation device, the push switch and the operation button of the operation device can also be respectively arranged on the two operation surfaces of the control device; wherein, the operation button and the knob can be arranged on the upper and lower sides of the grip portion. On the side, the user can operate with thumb and index finger together.

The present invention also provides a power cart, which has a bracket provided with a motor and a holding part, and the holding part is installed with the above-mentioned control device.

Preferably, the push switch and the knob of the control device are electrically connected to the motor to control the starting and output speed of the motor.

Preferably, the power cart also has an application device, and the operation surface of the control device is respectively provided with another push switch and an operation button to facilitate the user to operate the application device.

Figure 1 is a schematic diagram of a powered cart.

FIG. 2 is a partial schematic diagram of a power cart control device.

In order to clearly illustrate the specific implementation, structure and effect of this creation, the following descriptions are provided in conjunction with the diagrams:

Please refer to FIG. 1 and FIG. 2 , which are shown in the power cart and its control device. The power cart has two front and rear wheels to move forward along the working direction. The support 10 of the power cart is provided with a motor 20 and a handle 11 (holding The motor 20 is used to drive the driving wheel 21 of the power cart. The handle 11 provides the user to hold to maintain the walking balance and the walking direction of the power cart. The control device 30 is arranged between the handle 11 and the bracket 10 .

In this embodiment, the control device 30 is provided with a square casing and has two operation surfaces. A knob 311 is protruded toward the operation surface 31 of the handle 11 to control the output speed of the motor 20 , thereby controlling the running speed of the driving wheel 21 . The operation surface 35 perpendicular to the operation surface 31 is provided with the push switch 351 of the motor 20. The distance between the push switch 351 and the handle 11 is about the length from the thumb to the index finger of the palm of the hand. When the user holds the handle 11 with three fingers and the palm, The push switch 351 of the motor 20 can be operated by extending the index finger to activate or deactivate the motor 20 .

By arranging the control device 30 near the handle 11 and integrating the operating elements of the power cart motor 20, the user can use the index finger of one hand to control the power cart while holding the handle 11 with both hands to maintain the balance of the power cart. The knob 311 of the car and the push switch 351 do not require time for parking operations.

In this embodiment, the rotation axis of the knob 311 is parallel to the handle 11, the handle and the knob are located on the same operating surface and are arranged side by side up and down, giving the fingers a larger operating space. However, the knob 311 may also be directly arranged on the Column-shaped handle 11; in addition, the knob 311 and the push switch 351 can also be designed to be spaced at a considerable distance to avoid accidental touch during operation.

In addition to the motor 20 , the power cart of this embodiment is also provided with an application device, such as a spray device. The push switch 352 of the application device is arranged side by side with the push switch 351 , and the control device 30 can be provided with an operation button 312 to electrically connect the application device. An operation device to control the action of the application device (such as whether to start spraying pesticides and spraying pressure); wherein, the operation button 312 is protruded from the operation surface 31 of the control device 30, or is arranged on other surfaces of the control device 30 and enables The operation area of the operation button 312 faces the handle 11, and the operation button 312 and the knob 311 are respectively located on the upper and lower sides of the handle 11, whereby the user can use the thumb and index finger to control the operation button 312 and the knob 311, respectively, to control the spraying pressure intensity and the walking speed of the power cart. One-handed operation can be achieved.

In this embodiment, one of the operation surfaces 31 of the control device 30 makes the knob 311 have a specific operation direction A, as shown in FIG. The operation direction B is parallel to the handle 11. Since the operation directions A and B are perpendicular to each other, the effect of the above-mentioned one-hand operation can be achieved. In other embodiments, under the premise of locating the above-mentioned operating directions, the control device 30 may also have an irregular surface. For example, when the control device 30 has a small volume, when the user's palm is holding the handle, the index finger can extend to the back of the control device 30 (the control device 30 is far from another operating surface of the handle), at this time, the knob 311 can be set on the surface of the control device 30 away from the handle 11 .

To sum up the above, the power cart is equipped with a highly integrated control device, which is in line with the user's hand operation mode, and can be easily operated with one hand without spending additional parking time; moreover, this creation combines different on-off controls and outputs. Switches or buttons with different functions such as control are respectively installed on different operation surfaces of the control device, which can further reduce the risk of accidental touch by the user.
