Abstract

The utility model provides a bicycle light-emitting device, which belongs to daily articles, saves energy and is environment-friendly. The bicycle light-emitting device comprises a bicycle frame, andthe bottom portion of the bicycle frame is equipped with a center shaft, a rear shaft and a front fork. The bicycle light-emitting device is structurally characterized in that a positive conductive sheet and a negative conductive sheet are arranged outside the center shaft and are connected with a bulb, an iron core is fixed on the center shaft, and a coil, an N-pole permanent magnet and an S-polepermanent magnet are arranged outside the iron core.

Description

The bicycle light-emitting device

Technical field:

The utility model is to belong to daily living article.

Background technology:

Nowadays, though most of people is drived a car, because the blowdown contaminated environment of automobile, people begin to replace by bike going on a journey with automobile gradually; But at night is unsafe by bike.

The utility model content:

The utility model is exactly at the problems referred to above, and a kind of energy savings bicycle light-emitting device of environmental protection again is provided.

For achieving the above object, the utility model adopts following technical scheme, and the utility model comprises bicycle rack, and the bottom of bicycle rack is provided with axis, rear axle, front fork, its structural feature axis is outward cathode conductive film, cathode conductive film, and cathode conductive film, cathode conductive film link to each other with bulb; Be fixed with iron core on the axis, iron core is outside equipped with coil, and iron core is outside equipped with the permanent magnet of the N utmost point, the S utmost point.

The beneficial effects of the utility model:

When in night, using the utility model, can play good illuminating effect, and prevent the generation of unnecessary accident.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the partial enlarged drawing of Fig. 1.

The specific embodiment:

The utility model comprises bicycle rack 5, and the bottom of bicycle rack 5 is provided with axis 6, rear axle 7, front fork 3, is cathode conductive film 2, cathode conductive film 1 outside the axis 6, and cathode conductive film 2, cathode conductive film 1 link to each other with bulb 4; Be fixed with iron core 10 on the axis 6, iron core 10 is outside equipped with coil 9, and iron core 10 is outside equipped with the permanent magnet 8 of the N utmost point, the S utmost point.

When riding bicycle of the present utility model, allow the outer coil 9 of iron core 10 on the axis 6 in the magnetic field that the permanent magnet 8 of the N utmost point, the S utmost point forms, do cutting magnetic line movement, the electric current of generation makes bulb 4 luminous through cathode conductive film 2, cathode conductive film 1 output.

Claims
