Abstract

The utility model relates to a bicycle accessory, in particular to a simple device for indicating the turning of bicycles by flicker LED arrows, which comprises a control switch, LED lamps and a taillight box. The device is characterized in that the control switch is mounted on a bicycle handle and the taillight is mounted on a shelf.A battery is arranged in the taillight box. The taillight box is equipped with a circuit board. The circuit board is equipped with 20 yellow LED lamps connected in parallel to form a left arrow and a right arrow respectively.A single flash red LED lamp is connected in series with the left arrow and the right arrow respectively and the synchronous flickering of the ten LED lamps of the right or left yellow arrow is realized by the conversion of the switch.Each electronic component is in electric connection with each other.According to the utility model, the on and off of the current is controlled by the single flash LED.Compared with the prior art, the device optimizes the circuit and reduces the number of electronic components, wherein the function is single and the indication of the arrows is clear. The device is an indication lamp of high practicability and great potential.

Description

The easy device of flicker LED arrow prompting turning of bicycle

Technical field

The utility model relates to the annex on a kind of bicycle, especially relates to a kind of easy device of the LED of flicker arrow prompting turning of bicycle.

Background technology

Bicycle is a kind of vehicle that a lot of people use always, and China is again bicycle big country.Under the call of advocating low-carbon (LC), environmental protection, bicycle has obtained everybody liking especially and has praised highly, and becomes the trip mode of a kind of fashion, health gradually.By inquiry, find that the Cornering Lamp of bicycle also has some producers producing, but sale throughout the country seldom.Trace it to its cause, the Cornering Lamp of existing bicycle mainly has the following disadvantages: used electronic component is many, and fault is many, and is fragile, the repair rate height; Complex structure, the price height; Because of the lampshade area is little, direction indication is indeterminate; Additional functions such as illumination, loudspeaker are many, and the function of turning and pointing out has on the contrary weakened.

The utility model content

The purpose of this utility model is the easy device of a kind of LED of flicker arrow prompting of design turning of bicycle.It makes bicycle increase the function that can point out when turning, and is simple in structure, and low price, is a kind of practicality and explorative very strong warning light.

The utility model is by the following technical solutions: a kind of easy device of the LED arrow prompting turning of bicycle that glimmers, comprise master cock, the LED lamp, tail light box, it is characterized in that master cock is installed on the handlebar, taillight is installed on the shelf, battery is installed in the tail light box, one circuit card is arranged in the box, go up by 20 yellow leds be connected in parallel form respectively one left, to the right arrow, single dodge red LED series connection with it respectively with one, and control 10 LED that form yellow arrows respectively by the conversion of switch and glimmer synchronously, between each electronic component for being electrically connected.

Compared with prior art, the beneficial effects of the utility model are to have optimized circuit, have reduced electronic component, and function singleness is abbreviatied, and the arrow direction indication is clear and definite.

Description of drawings

Accompanying drawing 1 is a structural representation of the present utility model.

Among Fig. 1: 1 is master cock, and 2 is right-hand corner button shelves, and 3 are craspedodrome button shelves, and 4 is that turnon left button shelves, 5 are tail light box, and 6 are turnon left flicker arrow warning light, 7 mid point red lights, and 8 are right-hand corner flicker arrow warning light.

Accompanying drawing 2 is circuit diagrams of the present utility model.

Accompanying drawing 3 is that LED of the present utility model arranges scheme drawing.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

Accompanying drawing 1 structural representation of the present utility model.In the present embodiment, when the button of master cock 1 was pulled out right-hand corner button shelves 2, the right-hand corner flicker arrow warning light 8 on the tail light box 5 was glittering, and the prompting bicycle will right-hand corner; When pulling out turnon left button shelves 4, turnon left on the tail light box 5 flicker arrow warning light 6 is glittering, and the prompting bicycle will turnon left; When pulling out craspedodrome button shelves 3, there is not warning light bright on the tail light box 5.

Accompanying drawing 2 is circuit diagrams of the present utility model.Among the figure by 20 yellow leds be connected in parallel form respectively one left, to the right arrow, with the series connection with it respectively of a single sudden strain of a muscle red LED, and control 10 LED that form yellow arrows respectively by the conversion of switch and glimmer synchronously, between each electronic component for being electrically connected.The voltage at 10 yellow led two ends in parallel is 1.8V, and a single voltage that dodges the red LED two ends is 2.7V, and connecting with the battery of three joint 1.5V is 4.5V, just can make the flicker arrow warning light of turning glittering, need not external other electronic components again.This circuit makes full use of the break-make that single LED of sudden strain of a muscle realizes circuital current, and compared with prior art, the utility model has been optimized circuit, reduced electronic component, function singleness is abbreviatied, the arrow direction indication is clear and definite, is a kind of practicality and explorative very strong warning light.

Accompanying drawing 3 is that LED of the present utility model arranges scheme drawing.Among the figure 20 yellow leds be connected in parallel form respectively one left, arrow to the right, with single a sudden strain of a muscle in the middle of red LED places.Except pointing out from the direction of arrow the turn direction of bicycle, the red LED left side in the middle of can also being positioned at according to glittering yellow led still is the turn direction that bicycle is pointed out on the right side.

Claims

1. the LED arrow that glimmers is pointed out the easy device of turning of bicycle, comprise master cock, the LED lamp, tail light box, it is characterized in that master cock is installed on the handlebar, taillight is installed on the shelf, battery is installed in the tail light box, one circuit card is arranged in the box, go up by 20 yellow leds be connected in parallel form respectively one left, to the right arrow, single dodge red LED series connection with it respectively with one, and control 10 LED that form yellow arrows respectively by the conversion of switch and glimmer synchronously, between each electronic component for being electrically connected.
