S-shaped carbon-free dolly walking with variable space

Abstract

The invention relates to an S-shaped carbon-free dolly walking with a variable space. The S-shaped carbon-free dolly comprises a dolly frame, a drive device, a transmission apparatus and a turning device. The dolly can changes its direction through a crank rocker, a shaft connected with wheels is a rear wheel shaft, the rear wheel shaft is provided with a pinion, a rear gear engaged with the pinion is mounted on a driving shaft, a front gear engaged with the pinion is connected with a cam, the cam is connected with a pull bar, and a crank rocker mechanism can move through gear engagement. The gravitational potential energy is converted into mechanical energy to drive the dolly to move at a certain periodicity, and the dolly can avoid barriers arranged on a racing track when the dolly moves forwards. A coiling of the dolly is of a shape of circular truncated cone, so a potential energy block can fall at a uniform speed, the uniformity of the running speed of the dolly can be ensured, and the stability of the dolly during movement can be enhanced. The dolly frame is turreted, the whole weight can be light, energy loss caused by frictional force can be reduced, and the integrity is good, the cost is low.

Description

technical field [0001] The invention relates to a carbon-free trolley, in particular to a carbon-free trolley for racing in S-shaped variable pitch. Background technique [0002] A kind of competition-type carbon-free car. Requirements: Design a self-propelled car with direction control function driven by gravitational potential energy. It is required that the energy required for the car to complete all actions in the process of walking is obtained by converting the given gravitational potential energy. Not possible Use energy from any other source. The trolley is required to have a steering control mechanism, and this steering control mechanism has an adjustable function to adapt to competition venues with obstacles at different distances. The trolley is required to have a three-wheel structure. The given gravitational potential energy is obtained with a standard weight of 1Kg, and the dropable height of the weight is required to be 400±2mm. The width of the track is 2 m...

AI Technical Summary

Problems solved by technology

First, the driving device of the trolley wraps the traction rope directly on the wheel drive shaft, resulting in a small starting torque of the trolley, which is not conducive to the start of the trolley, and at the same time affects the driving distance of the trolley

Second, when debugging the car, due to the influence of the winding position and the length of the traction rope, the angle of the front wheel cannot be adjusted accurately, which causes inconvenience in debugging and affects the obstacle-crossing driving of the car

Third, there is no pitch-changing device in the trolley mechanism, which cannot adapt to competition venues with obstacles of different distances

Fourth, the components of the trolley are too complicated, and the processing cost is high, which does not meet the requirements of carbon-free and low-cost trolleys.
