Streamer crank pedal mechanism for sharing bicycle

Technical Field

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

Background

The sharing bicycle is an environment-friendly and green vehicle, and is widely popularized again along with the prevalence of the sharing bicycle.

In order to improve the safety of the shared bicycle during riding at night, the rear seat and the pedals of the shared bicycle are respectively provided with a reflective sheet, when the light of the bicycle irradiates on the reflective sheet, the reflective sheet can utilize the reflection of the light to play a role of warning, but the area of the existing reflective sheet is small, and particularly the reflective sheet on the pedals is easily shielded by the rear part of the heel and cannot form effective reflection; in addition, the existing reflector can emit light only through passive irradiation, and cannot play a role in actively emitting light to warn passing pedestrians, so that the overall warning effect is poor.

To this end, we propose a mechanism for sharing a streamer crank pedal for a bicycle to solve the above problems.

Detailed Description

The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

Example 1

As shown in fig. 1-2, a streamer crank pedal mechanism for a sharing bicycle comprises a center shaft 1, cranks 2 fixedly mounted at two ends of the center shaft 1, and pedals 3 rotatably connected to the tail ends of the cranks 2, wherein each pedal 3 comprises a pedal body 4 and a fixed shaft 5, the fixed shafts 5 and the cranks 2 are fixedly mounted, the pedal bodies 4 are rotatably mounted on the fixed shafts 5, a communicating cavity 6 is formed in the center shaft 1, a transparent connecting pipe 7 is fixedly connected to the inside of each crank 2, the fixed shafts 5 are made of transparent materials, a containing cavity 8 is formed in each fixed shaft 5, and the communicating cavity 6, the connecting pipe 7 and the containing cavity 8 are mutually communicated to form a closed channel 9.

The closed channel 9 is filled with the flowing liquid 10 and the fluorescent floating balls 11, the flowing liquid 10 is filled in the whole closed channel 9, the fluorescent floating balls 11 can be made in a mode that fluorescent powder is filled in the transparent ball shell, the flowing liquid 10 can be colorless transparent aqueous solution, a plurality of diffraction holes 12 are uniformly distributed on the side wall of the crank 2, attention needs to be paid to the fact that under the action of the diffraction holes 12, the light emitted by the fluorescent floating balls 11 is scattered due to diffraction, the irradiation range of the fluorescence is further increased, the pedal body 4 is of a hollow frame structure, the pedal body 4 is made of transparent materials, and what needs to be explained is that the connecting pipe 7, the fixing shaft 5 and the pedal body 4 can be made of transparent plastics.

In this embodiment, under the illumination of sunshine or other light sources, can make fluorescence float ball 11 absorption light energy, at the in-process of riding, fluorescence float ball 11 can sustained release energy, produces the light, reminds pedestrian's vehicle on the road to notice, plays the effect of warning, it needs to explain that, shared bicycle is when stopping, and two pedals 3 can distribute one on the other, and under the effect of buoyancy, fluorescence float ball 11 can remove to the top all the time, absorbs outside illumination more easily.

Under the effect of flowing liquid 10 buoyancy, fluorescence floats ball 11 and can follow the low department and remove towards the eminence, and at the in-process of riding, the position periodicity of two cranks 2 continuously changes, thereby make fluorescence float ball 11 constantly from the chamber 8 that holds of low department along the chamber 8 that holds of intercommunication chamber 6 and connecting pipe 7 towards the eminence remove, form fluorescence float ball 11 and last the effect that flows in airtight passageway 9, the luminous characteristic of cooperation fluorescence float ball 11, form the effect of flowing light, compare in traditional reflection of light piece, not only irradiation range is bigger, and can form the luminous effect of developments, stronger warning effect has.

Furthermore, the diameter of the fluorescent floating ball 11 is far smaller than that of the closed channel 9, so that the moving speed of the fluorescent floating ball 11 can be increased, and the volume of the fluorescent floating ball 11 is smaller than half of that of the closed channel 9, so that the movement effect of the fluorescent floating ball 11 is more obvious.

Example 2

As shown in fig. 3, the present embodiment is different from embodiment 1 in that: the included angle between the axis of the communicating cavity 6 and the axis of the middle shaft 1 is 15-30 degrees, when the axis of the communicating cavity 6 is in a vertical plane, the two cranks 2 are both in a vertical state, the crank 2 positioned on the upper side is communicated with the upper end of the communicating cavity 6, and the crank 2 positioned on the lower side is communicated with the lower end of the communicating cavity 6.

In this embodiment, because the intercommunication chamber 6 slope sets up for when fluorescence floats ball 11 and removes to intercommunication chamber 6 in, the condition of gathering is difficult to appear, can move to the eminence more smoothly, makes fluorescence float ball 11's removal orbit coherent more.

Example 3

As shown in fig. 4 to 5, the present embodiment is different from embodiment 1 in that: the refraction strip 13 of equal fixedly connected with semicircle pillar type on the three lateral wall of crank 2 is kept away from to pedal body 4, and the plane of the refraction strip 13 of semicircle pillar type is connected with pedal body 4's lateral wall, and the axis of three refraction strip 13 distributes along pedal body 4's whole body.

In this embodiment, since the refraction strips 13 are semi-cylindrical, it can be known from the refraction of light that the light emitted from the fixed shaft 5 will be dispersed all around (as shown in the left side of fig. 5) under the action of the refraction strips 13, so as to increase the irradiation range of the light; light received from the outside is focused in the middle (as shown in the right side of fig. 5) by the refraction strip 13, so that the fluorescent floating ball 11 in the fixed shaft 5 obtains more light energy.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
