Description

technical field [0001] The invention relates to a steering device, in particular to a laser radar-based obstacle avoidance steering device, a working method and a carbon-free car. Background technique [0002] Designing and producing carbon-free cars has gradually become a regional and even national mechanical design competition. Given a gravitational potential energy of 4 joules (height drop is 400 ± 2mm), a mass of 1kg, and a weight of Φ50×65 in size, according to the principle of energy conversion, design a self-propelled car driven by gravitational potential energy and with direction control function; It is a three-wheel structure with a steering control mechanism, and the steering control mechanism has an adjustable function or can quickly replace the structure to adapt to the competition field with obstacles at different distances. The energy driving the car to walk and turn can only be given by the given gravity. It is converted from potential energy, and other energ...

Problems solved by technology

[0003] Most of the steering mechanisms of existing carbon-free trolleys use cams, gears, crank rockers, and incomplete gears as the steering mechanisms driven by the trolley. These mechanisms have the following disadvantages: First, the processing of machine parts requires high precision and high cost. Difficult, in addition, parts are greatly affected by machining accuracy; second, the installation accuracy of parts is required, and are easily affected by temperature, making installation inconvenient; third, the size and weight of parts are large, which makes the size of the whole vehicle larger; fourth, there are many friction pairs , and the transmission chain is long, the driving resistance is large, resulting in serious energy loss, decreased control accuracy, and the steering of the car is not sensitive

The energy of traditional mechanical steering comes from the potential energy of heavy objects. The mechanical steering mechanism makes the whole vehicle bulky, and the increase of friction pairs greatly increases the traveling resistance. The energy to drive the trolley becomes very small, which directly limits the maximum distance the trolley can run.
