CN2174395Y - Alarm safety apparatus for bicycle - Google Patents

Abstract

The utility model provides an alarm safety apparatus for bicycles. The existing bicycle has no alarm apparatus in general, and is only provided with a reflector lamp at the rear of the bicycle, but the reflector lamp belongs to passive reflection, and has poor effect. The alarm safety apparatus for bicycle of the utility model comprises a luminous body, a luminous body driving circuit connected with the luminous body, batteries and an accommodation luminous body for supplying power to the luminous body and the luminous body driving circuit, the casings of the luminous body driving circuit and the battery, and an elastic hanging piece, wherein, the luminous body is exposed out of the front of the casing, and the back of the casing is fixed with the elastic hanging piece. The utility model has the advantage of active luminescence, and can be taken off at any time.

Description

Alarm safety apparatus for bicycle

The utility model relates to a kind of bicycle safety device of warning.

China is a bicycle big country, and the owning amount of bicycle is very big.According to the public security traffic department statistics, the traffic accident ratio that is caused by bicycle is also very high.And the present bicycle safety device of generally not warning is especially dangerous at night running, and the spot lamp effect of bicycle afterbody is very little, because it is a kind of passive refractive body, does not have under the more weak situation of light source or light source in night, and its glistening intensity is very weak.

The purpose of this utility model is to provide a kind of bicycle safety device of warning that can active illuminating.

Another purpose of the present utility model is to provide a kind of bicycle that can unload at any time safety device of warning.

Design of the present utility model is as follows: the bicycle of the present utility model luminary driving circuit that safety device comprises luminary, links to each other with luminary of warning, to the battery of luminary and luminary drive circuitry with hold luminary, the housing of luminary driving circuit and battery, luminary exposes outside the housing front, is fixed with an elasticity lacing film in the housing back.

As mentioned above, bicycle of the present utility model is warned has luminary in the safety device, the mode that adopts active illuminating to warn, therefore night the effect of warning better.In addition, outside this bicycle is warned the housing of safety device, be provided with the elasticity lacing film, this device can be hung over during use on bicycle rear portion reflector or the back vehicle frame, the time spent can not take off at any time, with anti-lost.

Describe an embodiment of the present utility model in detail below in conjunction with accompanying drawing.

Fig. 1 is the warn scheme drawing of safety device of bicycle of the present utility model;

Fig. 2 is the warn side diagrammatic sketch of safety device of bicycle of the present utility model;

Fig. 3 is the warn circuit block diagram of safety device of bicycle of the present utility model.

Referring to Fig. 1, Fig. 1 is the warn scheme drawing of safety device of bicycle of the present utility model, and the luminary 2 that works the effect of warning in this device is arranged on the front 11 of housing 1, luminary 2 adopts light-emitting diode in the present embodiment, with two groups of 6 branches, triad, each organizes used color difference.

As shown in Figure 2, be provided with an elasticity lacing film 3 at the reverse side 12 of housing 1, this elasticity lacing film 3 is concave shaped, and resilient material such as available red copper is made, and this sample device can hang on bicycle rear portion reflector or the back vehicle frame, and can block.

Fig. 3 is the warn circuit block diagram of safety device of bicycle of the present utility model.As shown in Figure 3, it is made up of battery E, luminary driving circuit 4 and luminary 2, battery E can save No. 5 batteries with two, be arranged in the housing 1, luminary driving circuit 4 can be with common oscillating circuit or its integrated circuit that is made of 555 integrated circuit, as red JAP wafer 700mm wavelength brightness 0.7mc.Because of genus known technologies such as 555 integrated circuit, just repeat no more at this.Luminary 2 adopts light-emitting diode, can certainly adopt other luminous elements such as good small electric bulb.As shown in Figure 3, also can be connected in series a K switch in battery E, this switch is arranged on housing 1 front (as shown in Figure 1).Above-mentioned battery E, luminary driving circuit 4 etc. all are arranged in the housing 1.

For this device can be used in the rainy day, outside housing 1, can coat the sealing gelatinous layer.
