Abstract

The utility model relates to a bicycle pedal with a luminous alarm sign, which is provided with a pedal. The middle part of the pedal is provided with a through hole and the circumference of the pedal is provided with a plurality of luminous bodies which are mutually cascaded. The two side edges of the through hole on the middle part of the pedal are provided with a coil induction device. The device is connected with a plurality of luminous bodies which are mutually cascaded. An axle center passes through the through hole on the middle part of the pedal and the axle center corresponds to the position of the coil induction device. The utility model is also provided with a magnetic field producing device. The bicycle pedal composed of the components can be automatically luminous when the pedal is rotated. The utility model has simple structure and can be luminous without using a battery.

Description

But the bicycle pedal of light-emitting caution

The utility model relates to a kind of bicycle device, particularly a kind of can luminous voluntarily bicycle pedal.

Early stage bicycle in design, because of considering the safety of night running, be equiped with Reflector the pole of its vehicle body and the appropriate location of wheel cap, in the hope of being reflected shinny its position that manifests by light when the night running, yet,, fail to manifest brightness at ordinary times because Reflector only can be shinny when being shone by light, so, the situation of finding that the reaction in evening is too late and causing the traffic accident generation is arranged promptly if steam turbine car steerman is failed careful attention; Therefore with the luminary be media and voluntarily the bicycle pedal of light-emitting flash just produced; but these pedals need be provided with battery except the installing of luminary, switch and control circuit; and still need for protective circuit and to do water-proofing treatment, cause defectives such as the complicated cost height of product configurations.

Main purpose of the present utility model provides and a kind ofly need not to use battery to respond to voluntarily to produce the luminous more simple bicycle pedal of structure that makes of electromotive force.

The technical solution of the utility model: mainly be provided with a pedal, the centre of pedal is provided with a through hole, around this pedal, be provided with the luminary that several are connected in series each other again, through hole both sides of the edge in the middle of the pedal are provided with inductive devices, inductive devices is connected with the luminary that several are connected in series each other, run through an axle center in the through hole in the middle of the pedal, this axle center corresponds on the position of inductive devices, is provided with magnetic field generation device.

When bicycle knight pushes pedals was advanced, the inductive devices on it can produce electric energy around the magnetic field generation device rotation in axle center, and it is bright that this electric energy can drive luminary.

Pedal of the present utility model produces electric energy because be with induction, therefore battery need not be arranged, the design of switch and circuit, unitary construction is practical simple, reduced manufacturing cost, and because the utility model does not have complicated accurate circuit and electronic component, so need not do water-proofing treatment especially, even the infiltration of rainwater and not hindering, fault rate is low.

In order further to understand structure of the present utility model, feature and effect, be elaborated with the preferred embodiment conjunction with figs..

Fig. 1 is the stereo appearance figure of the utility model bicycle pedal.

Fig. 2 is the profile construction scheme drawing of the utility model bicycle pedal.

Fig. 3 is the A-A cross section view of Fig. 2.

See also shown in the accompanying drawing as can be known, structure of the present utility model mainly contains a pedal body 10, establish several lamp sockets 11 around this pedal body for light-emitting diode 12 is installed, the length of these lamp sockets is bigger than light-emitting diode, can be fully ccontaining be good in it, the foot of these light-emitting diodes is to be connected in series each other and to connect two coil 14, this two coil is located at through hole 13 lateral margins in the middle of the pedal body, it is to run through aforesaid through hole that one axle center 20 is arranged again, the one end also stretches out pedal body 10 to be connected on the bicycle, it is solid on pedal body to detain that this axle center is provided with two grooves 22, on the position of the corresponding coil 14 in this axle center, be provided with the permanent magnet 21 of two arcs, the magnetic pole of this two magnet is to be S-N-S-N to be crisscross arranged, can produce inductive effects.

The bicycle pedal of forming by above-mentioned member, when pedal body 10 in bicycle is advanced round the axle center 20 whens rotation, coil 14 each field of magnetic forece through the arbitrary magnet 21 of cutting promptly can produce induced potential, it is shinny that this induced potential just can drive light-emitting diode 12, reaches the effect of caution; Because the shinny of these light-emitting diodes is to curl up the axle center with coil to produce synchronously, so that the speed of its shinny flicker and bicycle are stepped on speed is proportional, so can infer the vehicle gait of march by the flash speed of these light-emitting diodes.

Claims

But 1, a kind of bicycle pedal of light-emitting caution, mainly be provided with a pedal, pedal is provided with luminary, it is characterized in that: be provided with an axle center in the middle of the described pedal, around this pedal, be provided with several luminarys again, described axle center is provided with magnetic field generation device, is provided with inductive devices on the position of corresponding this magnetic field generation device of pedal, and the foot of described several luminarys is to be connected this inductive devices.
But 2, the bicycle pedal of light-emitting caution as claimed in claim 1 is characterized in that: the magnetic field generation device in axle center can be magnetite and constitutes.
But 3, the bicycle pedal of light-emitting caution as claimed in claim 1, it is characterized in that: luminary can be light-emitting diode.
