Technical Field

The invention belongs to the technical field of shared bicycles, and particularly relates to a crank pedal mechanism with a side warning mechanism for a shared bicycle.

Background

The bicycle is an environment-friendly and green vehicle, has wide application market in China, uses manpower as power and is generally not provided with other driving mechanisms.

The bicycle is when riding at night, generally through setting up a plurality of reflection of light pieces at its automobile body, to the reflection of the light of coming the car, play the effect of warning, but current bicycle reflection of light piece mostly sets up the downside at the back seat, on the avris of pedal and rear wheel fender, the reflection of light effect of this reflection of light piece receives the angle of shining of the light of coming the car and has great influence, reflection of light effect is not good, in addition, the side of bicycle does not have warning device almost, can't ride passerby formation a more comprehensive warning protection effect night.

Therefore, a crank pedal mechanism with a side warning mechanism for a bicycle sharing device is provided to solve the above problems.

Disclosure of Invention

The invention aims to provide a crank pedal mechanism with a side warning mechanism for a sharing bicycle, which utilizes the principle of magnetism to generate electricity to automatically emit light and has excellent warning effect, aiming at the problem of poor light reflecting effect of the existing bicycle reflecting piece.

In order to achieve the purpose, the invention adopts the following technical scheme: a crank pedal mechanism with a side warning mechanism for a shared bicycle comprises a driving disc, a fixed shaft, two groups of cranks and two pedals, wherein the fixed shaft is coaxially and fixedly connected in the driving disc, the two cranks are respectively and fixedly installed at two ends of the fixed shaft, the pedals are rotatably installed at the tail ends of the cranks, the lower ends of the pedals are fixedly connected with a wedge-shaped installation seat, permanent magnets are fixedly installed in the installation seat, and the two permanent magnets have the same magnetic poles and are obliquely arranged towards the same direction; the LED lamp comprises a fixing shaft, wherein the fixing shaft is arranged in a hollow mode, a light-emitting mechanism is arranged in the fixing shaft and comprises a power generation coil, a rectifier and an LED lamp, the rectifier and the LED lamp are connected to the power generation coil in series, the plane where the power generation coil is located is perpendicular to the plane where the two groups of cranks are located, and a light guide piece is arranged on the fixing shaft.

In the crank pedal mechanism with the side warning mechanism for the shared bicycle, the light guide part comprises transparent sealing covers arranged at two ends of the fixed shaft, and a light reflecting layer is arranged inside the fixed shaft.

In foretell share bicycle is with crank pedal mechanism that has side warning mechanism, light guide spare is including setting up the annular luminotron in the fixed axle both sides, annular luminotron passes through many light pipe and fixed axle intercommunication, the inside of annular luminotron, light pipe and fixed axle all is equipped with the reflector layer, annular luminotron fixed connection is on the lateral wall of initiative dish, the annular luminotron is located and inlays on the lateral wall of initiative dish outside and is equipped with the transparent ring of round.

In the crank pedal mechanism with the side warning mechanism for the shared bicycle, the transparent ring is pasted with the colored transparent belt, and the colored transparent belt comprises a plurality of sections of transparent sections with different colors, so that the light color of each part of the annular light emitting tube is different.

Compared with the prior art, this sharing bicycle is with crank pedal mechanism that has side warning mechanism's advantage lies in:

1. according to the invention, the mounting seat, the permanent magnets and the power generation coil are arranged, so that the positions of the two permanent magnets and the power generation coil are changed constantly in the process that the permanent magnets move along with the pedals continuously, the magnetic flux in the power generation coil is changed, induced current is generated to supply power to the LED, the warning effect on the side surface of the bicycle can be realized, and in addition, the pedal is enabled to be upward all the time due to the mounting seat, so that the bicycle is convenient to ride.

2. According to the invention, by arranging the annular light emitting tube, the light emitted by the LED lamp can be refracted and transmitted for multiple times by utilizing the reflecting layer and the light guide tube, so that the annular light can be emitted at the driving disc, the irradiation range of the light is further increased, and the warning effect is better, obvious and outstanding.

3. The annular light emitting tube emits light of various colors by arranging the colored transparent belt, and the colored light can continuously rotate and overlap due to the continuous rotation of the annular light emitting tube along with the driving disc, so that richer colors can be generated, the attention of people can be further attracted, and the warning effect is further improved.
