The invention discloses a bicycle braking energy conversion and recovery device based on electromagnetic induction. The device comprises a normal bicycle frame, a power generation hub, a bicycle taillight, a stop ring, a contact spring, a V-shaped brake mechanism, a brake cable and a conductor. The power generation hub is mounted on a rotating shaft of a front wheel and is internally provided with an electromagnetic induction coil, a bearing and an output end. The contact spring is mounted at the V-shaped brake mechanism, and the stop ring is mounted below the contact spring. One end of the bicycle taillight (an inner integrated rectifier filter voltage-stabilizing circuit) is connected with the output end of the power generation hub in a circuit manner, and the other end of the bicycle taillight is connected with the contact spring on the V-shaped brake mechanism through the conductor in a circuit manner. A contact of the contact spring is in union-separation connection with the stop ring under the action of the V-shaped brake mechanism so as to form a circuit loop during braking to power on and power off the bicycle taillight. The braking kinetic energy is converted into electric energy to power the bicycle taillight, so that energy saving, emission reduction and riding safety are achieved.
Description
technical field [0001] The invention relates to an energy conversion and recovery device based on electromagnetic induction when a bicycle brakes. Especially in the process of driving at night, the principle of electromagnetic induction can be used to convert kinetic energy into electrical energy during emergency braking, and power is supplied to the rear lights of the vehicle. Driving prompts and warnings can effectively prevent traffic accidents. Background technique [0002] At present, many bicycles do not have taillights, which can easily cause safety hazards; while bicycles with taillights are powered by batteries, discarded batteries will seriously pollute the environment, and replacing batteries will also increase costs. Contents of the invention [0003] The invention provides a novel environment-friendly and energy-saving bicycle brake device. Conventional bicycle tail lights do not have a light source, and can only display light after being irradiated by an exte...
