Carbon-free trolley capable of moving in 8 shape

Abstract

The invention discloses a carbon-free trolley capable of moving in an 8 shape. The carbon-free trolley comprises a frame, and a gravity mechanism, a driving transmission mechanism, a cam mechanism and a steering mechanism which are arranged on the rack, wherein the gravity mechanism comprises a vertical barrel, a duplex wheel, a flexible wire rope, a potential energy block and a wire winding shaft; the driving transmission mechanism comprises a driving gear, a driven gear, a right rear wheel shaft, a right rear wheel, a left rear wheel shaft and a left rear wheel; the cam mechanism comprises a cam and a push rod assembly; the steering mechanism comprises a linear spring, a first swing angle adjusting device, a first micrometer head, a swing angle sliding groove, a second swing angle adjusting device, a swing angle sliding block, a second micrometer head and a front wheel. The carbon-free trolley is provided with a primary transmission gear with the transmission ratio of 1 to 3.76, is simple and compact in structure and low in manufacturing cost; the duplex wheel is used for converting, the utilization rate of gravitational potential energy is high and the movement distance of the trolley is long; two micrometers are combined with the linear bearing, so that the carbon-free trolley is convenient to detach and debug; and the carbon-free trolley has the advantages of accuracy in adjustment, small errors and accurate movement track.

Description

technical field [0001] The invention relates to a mechanical racing car, in particular to a carbon-free trolley that runs in a figure-eight shape. Background technique [0002] The carbon-free trolley is a three-wheeled trolley that uses the potential energy of gravity as the only energy and has the function of continuous obstacle avoidance. For the carbon-free car in the figure-of-eight project, the competition requires the car to have a distance adjustment function, and under the action of gravity, it can accurately and repeatedly walk out of the figure-of-eight trajectory. The energy of the trolley is the kinetic energy provided by a 1kg potential energy block falling 400mm, and the pile distance ranges from 300mm to 500mm. Under the above conditions, if you want to improve the racing performance of the car, you must pay attention to the following points: First, because the energy provided is the same, if you want to circle more laps, you must consider reducing the weigh...

AI Technical Summary

Problems solved by technology

Although the trolley is energy-saving and environmentally friendly, has small errors and accurate running tracks, it still has the following defects: the carbon-free trolley includes four parts: the gravity assembly, the camshaft assembly, the steering fine-tuning mechanism, and the four-stage transmission mechanism. The structure is complex and difficult to manufacture. The multi-stage transmission mechanism includes multiple gears, which increases the production cost, and the multi-stage transmission reduces the utilization rate of the gravitational potential energy and shortens the walking distance of the trolley.
