CN2213674Y - Indicator for change direction of bicycle - Google Patents

Abstract

The utility model relates to a steering indicator for a bicycle, which is arranged on the front handle of the bicycle. The steering indicator can light by operating a knob twisting switch, can remind the attention of pedestrians by sounding, can enhance the driving safety performance of the bicycle, and meanwhile, has the decorative effect.

Description

Indicator for change direction of bicycle

The utility model turning of bicycle indicating device belongs to the turning of bicycle indicating device.

Bicycle does not have the special-purpose indicating device that turns at present, and along with popularizing of derailleur, the speed of a motor vehicle is accelerated, and when turning of bicycle, pedestrian and vehicle can not get clearly pointing out on every side, become the hidden danger of traffic accident.

The utility model turning of bicycle indicating device is at above-mentioned deficiency and design-calculated, it is by preceding indicator lamp, taillight, button switch and circuit part are formed, cyclist's Push switch, the forward and backward indicator lamp on corresponding one side is luminous and send whistling, and the people around can reminding from vision, the sense of hearing two aspects notes.

The utility model turning of bicycle indicating device is to adopt following scheme to realize, preceding indicator lamp profile strip shape, both sides are arrow pattern signs that red transparent material is made, and small bulb is installed for illumination usefulness in the back, the centre is a power pack, equipment 1.5V dry storage battery two joints also have splitter box in addition, and loud speaker and circuit card are installed, pig-tail wire is divided three directions, article one, guide the button switch of handlebar one side into, two other is led to taillight, throws light on small bulb in taillight inside.

The utility model turning of bicycle indicator structure is reasonable, and control comfort has improved the travel safety of bicycle, is fit to promote the use of.

The utility model turning of bicycle indicating device will be further described in conjunction with the accompanying drawings.

Fig. 1 is the utility model turning of bicycle indicator structure scheme drawing.

With reference to accompanying drawing 1, preceding indicator lamp ［ 1 ］ is a strip shape, and inside is divided into four frame box parts, and the two ends front surface is provided with red arrow pattern sign, the inner illuminating lamp ［ 4 ］ of installing.Installation loud speaker and circuit card are seen accompanying drawing 5 in splitter box ［ 2 ］, in power pack ［ 3 ］, place battery, for power pack ［ 3 ］ rear design that is enclosed in that makes things convenient for battery becomes the extracting formula to see accompanying drawing ［ 4 ］, button switch ［ 5 ］ device is seen accompanying drawing 3 at the handlebar position, and taillight ［ 6 ］ is installed in its structure of shelf both sides, back and sees accompanying drawing 2.

The utility model turning of bicycle indicating device embodiment: preceding indicator lamp ［ 1 ］ is used plastic injection-moulded making, cover plate and box body are formed before can adopting, also can adopt the combination of back cover plate and box body, concrete structure is decided by the producer's equipment and technical capacity, during two kinds of manufacture crafts practicality is not all had influence.Arrow pattern mandatory sign can with red plastic film paste or spraying all can, but at least should transmitted light, splitter box ［ 2 ］ position can process aperture for the loud speaker pronunciation, ［ 5 ］ make printed circuit board (PCB) it are installed in the loud speaker back with reference to the accompanying drawings.Power pack ［ 3 ］ rear design extracting formula cover plate makes and takes that battery is convenient and swift sees that accompanying drawing 4A is to view.Button switch ［ 5 ］ is fixed on the handlebar of a side, and its position should guarantee that the thumb of cyclist when driving can touch easily, and taillight ［ 6 ］ is installed on the perpendicular steady arm in shelf both sides, back, and its direction should be pointed to the rear.Draw two assemble lines from the circuit card of splitter box ［ 2 ］, one should lead to and turns round knob switch ［ 5 ］, and another is guided the back shelf into by vehicle frame and is divided into two stocks then and does not guide two taillights ［ 6 ］ into and see accompanying drawing 1.Fig. 5 is a circuit diagram, it adopts most typical COS/MOS digital integrated circuit, integrated package CD4001, this circuit can make loud speaker send 800Hz pulsetone square wave, loudspeaker impedance is chosen in 3-100 Ω scope, the resistance R x total resistance in back of connecting with loud speaker is got about 100 Ω, its order ground be guarantee Q1 power consumption in the scope that transistor power allows, the embodiment end.

Claims (1)

1, a kind of turning of bicycle indicating device, it is by the front and back indicator lamp, power supply and switch combination form, it is characterized in that preceding indicator lamp [1] is elongated is installed on the bicycle handle bar, and there is red arrow pattern sign at preceding indicator lamp [1] two ends, and inside is provided with splitter box [2], power pack [3], illuminating lamp [4], button switch [5] is installed in handlebar one side, and taillight [6] is installed in shelf both sides, back.
