Description

A carbon-free powered car

technical field

The invention relates to a bicycle trolley in the technical field of scientific and technological innovation, in particular to a carbon-free power trolley.

Background technique

With the development of science and technology, energy consumption is increasing day by day, and coal, as a precious wealth given to mankind by nature, has played a pivotal role in the development of human society for a long time. However, due to people's huge demand for coal, coal resources are decreasing day by day and approaching exhaustion. With the improvement of people's awareness of energy conservation and environmental protection, the concept of carbon-free has been increasingly put on the research topic. The concept of cleaner, more environmentally friendly, more energy-saving and more efficient is also deeply rooted in the hearts of the people.

In this context, the carbon-free car has gradually become a regional and even national mechanical innovation design competition. In this engineering training comprehensive ability competition, each team member is required to independently design and manufacture a bicycle with a directional control function, and is required to complete all actions during the walking process. The energy required is converted from the gravitational potential energy of the falling weight given, and energy from any other source cannot be used.

The carbon-free trolley is a bicycle trolley with directional control function driven by gravitational potential energy. The trolley has a three-wheel structure with a steering control mechanism, and the steering control mechanism should have a structure that can be quickly replaced to adapt to the competition field with obstacles of different distances; the given gravitational potential energy is uniformly used during the competition. A standard weight with a mass of 1Kg (Φ50×65mm, made of carbon steel), and the dropable height of the weight is required to be 400±2mm.
