Embodiment 1

[0022] Such as Figure 1-2 As shown, a streamer crank pedal mechanism for shared bicycles includes a central axis 1, a crank 2 fixedly installed at both ends of the central axis 1, and a pedal 3 rotatably connected to the end of the crank 2. The pedal 3 includes a pedal body 4 and The fixed shaft 5, the fixed shaft 5 and the crank 2 are fixedly installed, the pedal body 4 is rotatably installed on the fixed shaft 5, the central shaft 1 is provided with a communication cavity 6, and the crank 2 is fixedly connected with a transparent connecting pipe 7, the fixed shaft 5 Made of transparent material, the fixed shaft 5 is provided with an accommodation chamber 8 , and the communication chamber 6 , the connecting pipe 7 and the accommodation chamber 8 communicate with each other to form a closed channel 9 .

[0023] The airtight channel 9 is filled with a flow liquid 10 and a fluorescent floating ball 11, the flow liquid 10 fills the entire airtight channel 9, the fluorescent floa...

Embodiment 2

[0028] Such as image 3 As shown, the difference between this embodiment and Embodiment 1 is that the angle between the axis of the communication chamber 6 and the axis of the central axis 1 is 15°-30°, and when the axis of the communication chamber 6 is in a vertical plane , the two cranks 2 are in a vertical state, and the crank 2 on the upper side communicates with the upper end of the communication chamber 6 , and the crank 2 on the lower side communicates with the lower end of the communication chamber 6 .

[0029] In this embodiment, since the connecting chamber 6 is arranged obliquely, when the fluorescent floating ball 11 moves into the communicating chamber 6, it is not easy to gather, and it can move to a high place more smoothly, so that the moving track of the fluorescent floating ball 11 is smoother. coherent.

Embodiment 3

[0031] Such as Figure 4-5 As shown, the difference between this embodiment and Embodiment 1 is that: the three side walls of the pedal body 4 away from the crank 2 are fixedly connected with semi-cylindrical refraction strips 13, and the plane of the semi-cylindrical refraction strips 13 Connected with the side wall of the pedal body 4 , the axes of the three refraction strips 13 are distributed along the body of the pedal body 4 .

[0032] In this embodiment, since the refraction strip 13 is semi-cylindrical, it can be seen from the refraction of light that the light emitted from the fixed axis 5 will diverge around under the action of the refraction strip 13 (such as Figure 5 Shown on the left side of the center), increase the irradiation range of the light; the light received from the outside will be focused in the middle under the action of the refraction strip 13 (such as Figure 5 Shown on the right side in the middle), so that the fluorescent floating ball 11 in the ...

Abstract

The invention belongs to the technical field of shared bicycles, and in particular relates to a streamer crank pedal mechanism for shared bicycles, which includes a central shaft, a crank fixedly installed at both ends of the central shaft and a pedal rotatably connected to the end of the crank, and the pedal includes a pedal body and the fixed shaft, the fixed shaft and the crank are fixedly installed, the pedal body is rotatably installed on the fixed shaft, the central shaft is provided with a connecting cavity, the crank is fixedly connected with a transparent connecting pipe, the fixed shaft is made of transparent material, and the fixed shaft An accommodating cavity is provided, and the communication cavity, the connecting pipe and the accommodating cavity are connected to each other to form a closed channel, and the closed channel is filled with flow liquid and fluorescent floating balls. The invention releases bright light at night by setting fluorescent floating balls to play a role of vigilance. In addition, because the positions of the two cranks are always changing during riding, the fluorescent floating balls move back and forth in the closed passage to form streamers. Compared with the traditional reflective sheet, it has the advantages of large irradiation range and strong warning effect.

Description

technical field [0001] The invention belongs to the technical field of shared bicycles, in particular to a streamer crank pedal mechanism for shared bicycles. Background technique [0002] Shared bicycles are an environmentally friendly and green means of transportation. With the popularity of shared bicycles, they have been widely promoted again. [0003] In order to improve the safety of shared bicycles riding at night, reflective sheets are installed on the back seat and pedals of shared bicycles. When the light of a vehicle shines on the reflective sheet, the reflection of light can be used to play a warning role. However, the existing reflectors have a small area, especially the reflectors on the pedals, which are easily blocked by the rear of the heel and cannot form effective reflections; in addition, the existing reflectors must be illuminated passively and cannot emit light. It plays the role of actively emitting light to warn passing pedestrians, but the overall w...
