Description

Technical Field

[0001] The present invention relates to a control device, and more particularly to a control device and an electric vehicle comprising the control device. Background Art

[0002] Low-speed functional electric vehicles include small pump trucks for casting structural columns, electric carts, electric self-dumping carts, etc. This type of electric vehicle has a slow travel speed and no driving seat. The driver needs to follow the moving electric vehicle on foot and control the steering, braking, and speed of the electric vehicle at the same time. There are many disadvantages in the existing driving devices. For example, an electric cart proposed in Patent No. 201520842271.1 and an electric cart proposed in Patent No. 201620874049.4 control the speed and travel direction of the electric cart by a control arm or a brake steering rod, and brakes are applied by pressing down the direction control arm or the brake steering rod. When the vehicle is reversing, going uphill or downhill, or when the driver is too close to the electric vehicle, the downward pressing operation is very difficult for the driver, which increases the unsafe factor.

[0003] Patent application number: 2017210418696 proposes a multifunctional centralized control mechanism that can control the direction, speed, forward and reverse of the vehicle. The braking function can be achieved by applying thrust or pulling force to the operating handle in the opposite direction of travel. The operation is convenient, but the main rope wheel of the centralized control device needs to rotate when turning, and the pull rope and the lead tube will swing with the rotation of the main rope wheel, causing the wire tube to be entangled and worn. In addition, the pull rope c and the pull rope a are connected to a brake actuator at the same time. When an electric three- or four-wheeled cart needs to brake more than two wheels, more pull ropes are required, which swing with the rotation of the main rope wheel, which is not beautiful, has a higher failure rate, and an unreasonable layout.
