Carbon-free trolley

Abstract

The invention discloses a carbon-free trolley. The carbon-free trolley comprises a trolley frame and is characterized in that a weight power assembly capable of converting gravitational potential energy of a weight into power energy, a drive belt wheel assembly connected with the weight power assembly, a crank connecting rod assembly, a driven cam assembly connected with the drive belt wheel assembly and used for pushing the crank connecting rod assembly to move, a drive wheel connected with the drive belt wheel assembly, a steering wheel connected with the crank connecting rod assembly and adriven wheel rotatably installed on the trolley frame are installed on the trolley frame, the drive wheel, the steering wheel and the driven wheel are in a triangular distribution and respectively make contact with the ground to horizontally support the trolley frame, the steering wheel is located in front of the drive wheel and driven wheel, the weight power assembly pulls the drive belt wheel assembly to move through lowering of the weight, and therefore the driven cam assembly and the driven wheel are driven to move; the crank connecting rod assembly moves with the driven cam assembly, thesteering wheel is driven to steer, and the driven wheel rolls with moving of the driven wheel and the steering wheel to make the trolley run.

Description

technical field [0001] The invention relates to a carbon-free trolley, which belongs to the technical field of machinery. 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 by a standard weight of 1Kg, and the dropable height of the weight is required to be 400±2mm. The track width is 2 meters and the start line is equally ...

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.
