Abstract
The utility model discloses a safety warning device of a bicycle, relating to the technical field of alarming. The device is composed of a pulse type power supply which is installed on a bicycle wheel axle and a plurality of warning lights which are installed at the tail part of the bicycle; and the plurality of the warning lights are connected in parallel and then are connected with the pulse type power supply. The safety warning device of the bicycle has the advantages that: batteries are not needed, a warning signal can be sent out in the movement process of the bicycle so that the safety in the riding process is improved, and the price is cheap.
Description
Technical field
The utility model relates to the alarm technique field, specifically is a kind of bicycle safe alarming device.
Background technology
At present bicycle is as the main vehicle, and riding night exists very big traffic hidden danger, especially on highway communication people car mixes row and country and do not have the road of street lamp, rides, and accident has generation more, must adopt the signal lamp alarming device.If do power supply with storage battery, increase the load carrying ability of bicycle, if do power supply, will regularly replace, also must take damp-proof device, very inconvenience with dry storage battery.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the utility model provides a kind of bicycle safe alarming device, in the cycle racing process, can send alarm signal.
The utility model is realized with following technical scheme: a kind of bicycle safe alarming device, on the wheel shaft of bicycle, pulsed power supplies is installed, and at the afterbody of bicycle a plurality of light-emitting diodes are installed, be connected with the pulse power after a plurality of light-emitting diode parallel connections.
The beneficial effect of the utility model is: do not need battery, in the cycle racing process, can send alarm signal, improved security row in the driving process; Low price.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 is the utility model structural representation;
Fig. 2 is the power source generator structural representation;
Fig. 3 is a diode mounting structure scheme drawing.
Among the figure: 1, pulsed power supplies, 11, the annulus runner, 111, breach, 12, power source generator, 121, permanent magnet, 122, iron core, 123, coil, 2, Warning light, 3, housing, 4, support.
The specific embodiment
As depicted in figs. 1 and 2, the bicycle safe alarming device is made up of with the Warning light 2 that is installed in the bicycle afterbody the pulsed power supplies 1 that is installed on the bicycle shaft.A plurality of Warning lights 2 parallel connection backs are connected with pulsed power supplies 1.
In the present embodiment, install annulus runner 11 and bicycle quick are concentric, and depend on the spoke, because the annulus runner diameter is less, the out of roundness of bicycle rim does not influence its serviceability.On vehicle frame, be fixed with power source generator 12, guarantee that the gap between producer iron core 121 and the annulus runner 11 is 0.5mm.Warning light 2 adopts light-emitting diode, and 3 ~ 4 light-emitting diode parallel connections are contained in the bicycle afterbody.When wheel revolutions, pulsed power supplies begins generating, makes lumination of light emitting diode, rides night and sends caution to front vehicle.
As shown in Figure 3,3 ~ 4 light-emitting diodes are packed on the rectangular plastic plate, the rectangular plastic plate is contained in the bicycle rear portion with screw, light-emitting diode is connected receive pulsed power supplies behind the resistance, can realize the light-emitting caution when wheel advances.
Working process: with two terminations of A, B of coil among Fig. 1 as the power supply output lead, respectively at Fig. 3 in light-emitting diodes pipe assembly A1, B1 connection terminal link to each other.
When wheel revolutions, rotate synchronously with the annulus runner and the wheel of the concentric installation of wheel, utilize electromagnetic induction principle; During the rotation of annulus runner, the air gap of the breach of annulus runner and power source generator iron core changes, and the magnetic flux through the power source generator coil is changed; Therefore just produce the alternating electromotive force of induction in the coil; This alternating electromotive force inputs to light-emitting diode, makes led lighting, because alternating electromotive force receives the influence of vehicle wheel rotational speed bigger; Burn out light-emitting diode when preventing overtension, series connection one resistance in circuit.This kind device can be ignored the bicycle running resistance, and when the speed of a motor vehicle was low, LED flash was luminous; When the speed of a motor vehicle was higher, just visible light emitting diode (VLED) was luminous continuously, to front vehicle alarm signal is provided; Cyclist's safety is ridden, provide failure-free to protect behind.
Claims (3)
