Problems solved by technology

However, the carbon-free cars of the existing technology are not perfect in the application of intelligent obstacle avoidance, speed change, and full use of energy functions, and further research and development and improvement are needed.
[0003] Most of the existing carbon-free trolleys wind the wires on the conical winder ratio to achieve the purpose of torque change in a small range, so as to realize the function of uphill and downhill. This method is relatively mechanical, and the human error is large, and the winding position is different. If the error is too large, it is easy for the trolley to stop at the ramp without changing the winding position after the trolley arrives at the ramp. In the existing trolley, the heavy objects are falling during the whole downhill process, which increases the energy loss.

Embodiment

[0046] For this type of infrared ranging sensor, the relationship between the data input into the single-chip microcomputer and the distance of the obstacle directly in front can be fitted as an inverse proportional function, and the detected original data is set as value, then the segmented function (when value<30, f( value)=30; when value≥30, f(value)=[67870.0 / (value-3.0)]-40.0) after processing, the processed data f(value) is positively correlated with the obstacle distance at 10-80cm .

[0047] A certain experimental data processing process: At this time, the car is relatively close to the obstacle on the left, and the initial data obtained by the single-chip microcomputer is 143 left rear, 114 left front, 30 right rear, and 35 right front; firstly, the obstacle is obtained by processing the function f(value) Distance parameters: At this time, the left rear distance parameter is 434, the left front distance parameter is 571, the right rear distance parameter is 2473, and t...

Abstract

The invention discloses a carbon-free trolley which is provided with a neutral sliding mechanism and capable of intelligent obstacle avoidance. The carbon-free trolley includes a base plate, a power mechanism, a transmission mechanism, the neutral sliding mechanism and an obstacle avoidance mechanism, wherein the power mechanism includes a support frame, a weight, a pull wire and a winding base, the transmission mechanism includes a first transmission shaft, a second transmission shaft, a walking shaft, a winding shaft, a first-level transmission big-gear wheel, a first-level transmission small-gear wheel, a second-level transmission big-gear wheel, a pair of walking rear wheels and a second-level transmission small-gear wheel, the first-level transmission big-gear wheel is mutually meshedwith the first-level transmission small-gear wheel, the second-level transmission big-gear wheel is mutually meshed with the second-level transmission small-gear wheel, the neutral sliding mechanismincludes a coder, a shift steering engine, a single chip microcomputer and a neutral plate, and the obstacle avoidance mechanism includes multiple infrared distance measuring sensors and a swerve steering engine. The carbon-free trolley has the advantages that on a downhill, gravitational potential energy can be saved, and during operation, intelligent obstacle avoidance can be achieved, so that it is ensured that the trolley travels at a constant speed, and operation is smooth and steady.

Description

technical field [0001] The invention relates to the technical field of intelligent vehicles. More specifically, the invention relates to a carbon-free trolley with a neutral sliding mechanism and capable of intelligent obstacle avoidance. Background technique [0002] With the development of science and technology and people's advocacy of the concept of carbon-free, the design of carbon-free cars is becoming more and more ingenious, and the production is becoming more and more sophisticated. According to the requirements of the 5th National Engineering Training Comprehensive Ability Competition, the carbon-free car is a self-propelled car with direction control function driven by gravity potential energy; the car has a three-wheel structure and has a steering control mechanism, and the energy driving the car can only be given by The gravitational potential energy is converted from other energy sources. The given gravitational potential energy is 4 joules (taking g=10m / s 2...
