Electric handling equipment steering control power wheel device

Abstract

An electric handling equipment steering control power wheel device is disclosed. Two front wheels are located at the bottom front of the electric handling equipment, and two rear wheels are located at the bottom rear. A fully rotatable power wheel assembly is also provided. An electronically controlled joystick is located above the rear. The fully rotatable power wheel assembly includes a power wheel pivotally mounted below a 360-degree rotatable base. The power wheel is driven by a servo motor for rotation, while the base is oriented in one direction by a servo motor. The operator can control the direction and speed of the power wheel in real time by shaking or pushing / pulling the joystick. This allows the electric handling equipment to be driven by the manually controlled electronically controlled joystick to perform in-situ or near-in-situ steering operations with a minimal turning radius, significantly improving maneuverability and operational efficiency in confined spaces.

Claims

1. A steering control power wheel device for an electric handling equipment, comprising: An electric handling device is provided with a frame or an electrical box at the rear. The electrical box contains a circuit controller, and a battery, either inside or outside the electrical box, is electrically connected to the circuit controller. The electric handling device has two front wheels at the front bottom and two rear wheels at the rear bottom. A fully rotatable power wheel assembly is located at the bottom of the electric handling device. This assembly includes a directional servo motor electrically connected to the circuit controller, a wheel-powering servo motor electrically connected to the circuit controller, and a large gear pivotally mounted on a base capable of 360-degree rotatable rotation. The directional servo motor is fixed on the base, and its power drives a small gear to mesh with the large gear. The wheel-powering servo motor is also fixed on the base, and its power drives a power wheel pivotally mounted below the base. An electronically controlled rocker arm is electrically connected to the circuit controller and is located above the vehicle frame or the electrical box. When the electronically controlled rocker arm is manually rocked or pushed / pulled, the drive wheel can immediately react and adjust its direction of travel in all directions, enabling the electric handling equipment to rotate with the minimum turning radius to adapt to small spaces.

2. The electric handling equipment steering control power wheel device as described in claim 1, wherein the electric handling equipment is selected from at least one of the group consisting of a manual guide forklift, an electric lifting platform, an electric trolley, and an electric stacker.

3. The electric handling equipment steering control power wheel device as described in claim 1, wherein the battery may be a stationary battery or a quick-change battery.

4. The electric handling equipment steering control power wheel device as described in claim 1, wherein the two rear wheels are movable wheels that can rotate 360 ​​degrees, the two front wheels are fixed wheels, and the omnidirectional rotatable power wheel set is located at the rear bottom, so that the electric handling equipment can perform steering operations with the two rear wheels as the fulcrum of rotation and the minimum turning radius.

5. The electric handling equipment steering control power wheel device as described in claim 1, wherein the two rear wheels and the two front wheels are movable wheels that can rotate 360 ​​degrees, and the omnidirectional rotatable power wheel set is located in the middle of the four wheels, so that the electric handling equipment can perform steering operations with a near-stationary minimum turning radius.
