Abstract

The invention relates to a mechanical brake energy regeneration bicycle. A transmission mechanism is connected with a rear axle of the bicycle via a first chain wheel and a first overriding chain wheel and is connected with a spring energy accumulator through the engagement of a first bevel gear and a second bevel gear with a third bevel gear; and a control mechanism comprises an energy storage type damper brake, a forward boosting brake and a backward assisting brake installed on a handlebar, and the brakes are respectively connected with corresponding cam draw bars in the transmission mechanism via brake cables. The bicycle regenerates brake energy in a mechanical way and releases the energy during starting or acceleration, and the purposes of energy saving and environmental protection are achieved. Four-stage transmission is adopted as input, symmetrical four-stage transmission is adopted as output, and the energy utilization efficiency is high; the mechanical control mechanism has simple structure, low cost and easiness in operation and conforms to the riding habit; the spring energy accumulator has light weight and small size and is used as a bicycle beam, and the appearance of the bicycle body is not changed; and the bicycle also has backward function.

Description

technical field [0001] The invention relates to a bicycle, in particular to a mechanical braking energy recovery bicycle using a spring as an energy storage element. Background technique [0002] At present, with the massive exploitation of human beings, the supply of global energy resources is becoming more and more tense, and energy conservation and environmental protection have become a major issue in society. At present, my country's bicycle market mainly sells electric bicycles and ordinary human-powered bicycles. These two bicycles are braked by traditional friction braking. Frequent braking converts a large amount of kinetic energy into heat energy and loses it in vain. In order to recover this part of the braking energy, there are currently two ways: one is to convert the motor of the electric bicycle into a dual-purpose motor that can be used as a motor or as a generator through complex designs such as circuit conversion, and the brake brake The kinetic energy is c...
