Pure gravity-driven environment-friendly trolley capable of intelligently avoiding obstacle

Abstract

The invention discloses a pure gravity-driven environment-friendly trolley capable of intelligently avoiding an obstacle. The pure gravity-driven environment-friendly trolley comprises a driving mechanism, a transmission mechanism and an intelligent steering mechanism, wherein the driving mechanism is mounted in the middle part of a base plate; the transmission mechanism is mounted at the rear part of the base plate; the intelligent steering mechanism is mounted at the front part of the base plate. The pure gravity-driven environment-friendly trolley makes use of three ultrasonic sensors to detect an obstacle condition of a racing track, analyzes and processes the obstacle according to a detection result signal and automatically selects a proper track for steering forwarding. By the adoption of a circuit and the sensors for control of steering, a conventional mechanical steering mechanism is eliminated; compared with conventional manual adjustment, steering adjustment is much easier; the trolley can automatically detect and avoid the obstacle, so that the racing track adaptability of the trolley is improved, namely even if the obstacle is distributed randomly, the trolley can run normally; moreover, the machining and manufacturing cost of the trolley is reduced. Therefore, the use range of the trolley is expanded.

Description

technical field [0001] The invention relates to a driving trolley, in particular to a pure gravity-driven environment-friendly trolley capable of intelligent obstacle avoidance through ultrasonic detection controlled by a single-chip microcomputer. Background technique [0002] In recent years, in the National College Students Engineering Training Comprehensive Ability Competition, the self-propelled car driven by pure gravity has been selected as the competition topic. In the 5th National Undergraduate Engineering Training Competition in 2016, for the first time, the proposition of an autonomous obstacle avoidance car requiring electronic control appeared. The competition requires the car to retain the gravity potential energy drive and add the function of autonomous tracking and avoidance steering control. [0003] Existing self-propelled trolleys driven by pure gravity generally use purely mechanical structures (crank-rocker mechanism, sinusoidal mechanism, space four-ba...
