Description

Bicycle theft-prevention electric whistle lamp

The utility model relates to a kind of bicycle accessory, specifically a kind of antitheft electric whistle lamp.

In the Chinese patent storehouse, disclose the patent (ZL92221635) of several pieces of bicycle lamp's patents and one piece of Electronic bell.The dynamo lighting set patent is to utilize several different modes to produce electric energy, for the car light power supply, makes it to realize illumination functions.Electronic bell then is buzzer circuit migrating on human powered vehicle.The shortcoming of these patents is function singlenesses, and to the present increasing stolen problem of bicycle, also without any preventing effect.

The purpose of this utility model just provides a kind of illumination of not only can having blown a whistle, but also the antitheft electric whistle lamp of multifunction bicycle that can anti-theft alarm, overcoming the deficiencies in the prior art, and can promote social stability.

The utility model is achieved in that antitheft electric whistle lamp includes power supply E and electric light branch road, is parallel with the buzzer phone branch road at the two ends of electric light branch road, is serially connected with K switch 2 in the buzzer phone branch road, is parallel with alarm control circuit at the two ends of K switch 2.

Design philosophy of the present utility model combines buzzer phone exactly with illuminating lamp, make the electric whistle lamp of an one, and make full use of the function of buzzer phone, alarm control circuit is set in its switch ends, make when the situation that unusual shake-up vehicle is arranged takes place, buzzer circuit is connected in the alarm control circuit action, makes it to pipe continuously, thereby cause the relevant personnel's vigilance, in time check vehicle, or directly draw back the ruffian with fear, play theft-proof effect thus.

Advantage of the present utility model is to integrate and blows a whistle, illumination and anti-theft alarm, and function is many, compact conformation, flexible and convenient to use, both can ensure the personal safety in when driving, but alarming anti-theft again, reduce property damage, the stable situation to society also can play positive facilitation.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1, Fig. 2 are front view of the present utility model and birds-eye view.

Fig. 3 is schematic circuit diagram of the present utility model.

As shown in Figure 3, electric light L and K switch 1 serial connection constitute the electric light branch road, and power supply E is 3 volts of direct supplys.Buzzer phone B and K switch 2 serial connections constitute the buzzer phone branch road, are parallel to the two ends of electric light branch road.Two ends in K switch 2 are parallel with alarm control circuit.Alarm control circuit is made up of silicon control G and band switch.Select switch Ka in the band switch is connected between the end of the negative electrode of silicon control G and K switch 2, and at least one K switch 3 in the band switch is connected between the trigger electrode and anode of silicon control G, and receives the other end of K switch 2 again.Be parallel with rolling dynamic sensor Kb at the two ends of K switch 3.To the band switch that Kn formed, be equivalent to a coded lock in this device by select switch Ka and K switch 3.Set the position at one, select switch Ka opens, and this device is in blows a whistle and illumination condition normally, and this position is called flute lamp position, and the owner that buys car in installments normally uses by bike the time.On other band switch positions except that this, select switch Ka all is in closure state.Promptly before owner leaves, band switch is pulled away out flute lamp position, make this device be in alert status.At this moment, move or rock bicycle if any the people, the dynamic sensor Kb that then shakes connects the trigger electrode of silicon control G, makes the silicon control conducting, short circuiting switch K2, and then buzzer phone sends and rings.If stir band switch this moment arbitrarily, the short of flute lamp position that pushes normality, and when other positions, then all have a K switch 3 or Kn closure, and make silicon control continue triggering and conducting, realized the warning of blowing a whistle continuously.

Band switch in the alarm control circuit also can adopt the knob multichannel cipher switch that contact electrode is set on many ring printed circuit board (PCB)s to substitute.

In addition, for preventing that the car people destroys this device by the cover cap of dismantling this device steathily, also be parallel with dismounting trigger switch Kc at the two ends of K switch 3, this switch is the earphone socket shape trigger switch that is provided with in the fastening screw of cover cap.As long as screwdriver extend in the fastening screw rotates tightening screw, will connect switch Kc earlier, make the silicon control triggering and conducting, this device sends electric whistle sound.

As shown in Figure 1, 2, this device is arranged in the strip shape housing 1, and electric light 3 is at the front end of housing 1, and light switch 7 is in housing one side, and buzzer stop 2 is located at case top, is convenient to push.Band switch 6 also is arranged on housing one side.For adapting to different road conditions and driving people's different needs, lamp 3 and housing 1 can be made the mode that is rotatably connected, the knob 4 of adjusting lamp 3 irradiating angles is set in the side of housing 1.Among Fig. 1, also be provided with fixed card 5, captive joint with handlebar with convenient in the bottom of housing 1.
