By accompanying drawing as can be known, the utility model loam cake of end box (20) being arranged and fastening with it (10), the fixture on end box (20) outer bottom is (solid with the utility model by it Fix on the handlebar of bicycle) draw-in groove (231) is arranged and another by band deep-slotted chip breaker and an end End has holder (23) and an end of screw (232) to be plugged on draw-in groove (2 31) tongue in (401) and the other end have the arc folder of corresponding screw (402) Sheet (40) and screw (41) form, and form by having installed on it in the end box (20) The circuit board of the electronic component of operating circuit (30), its design feature are box of the described end (20) loudspeaker (16) are equipped with and there is back shroud (22) at its rear portion in the base plate front portion Battery tray (21) is before the box body that is made up of box of the described end (20) and loam cake (10) End is band reflector (142) and the lampshade (14) of bulb (141), institute is housed State the code switch that is respectively equipped with two to six groups of parallel connections in the switch groove (11) of box body both sides (12) and an one pole dibit change-over switch (13), loam cake (10) rear portion is provided with Horn switch button (15) is provided with a vibroswitch (17) in the described box body.

Fig. 6 has provided operating process of the present utility model (operation principle) figure, and (this figure is circuit Structured flowchart). When change-over switch (13) was opened to a side, the utility model can produce The effect of night illumination replaces the light harvesting reflecting plate at night in existing bicycle the place ahead, allows the cyclist There is light to lead the way; And when change-over switch (13) is opened to opposite side, code switch (12) Behind the setting code, when bicycle is vibrated (vibroswitch (17) connection), loudspeaker (16) send at once the sound and produce caution flicker illumination, joyriding is feared not Dare steathily car, and car owner or passerby can perceive immediately. Must by the time remove the loudspeaker sound behind the password And light flash just can stop. It (is that switch (12) is whole that many group codings must all be disengaged Be disengaged) after, alarm signal just can be eliminated. By horn switch button (15), device Realize the bicycle bell effect.

The used circuit of the utility model is the common circuit of prior art, and is not subjected to electricity shown in Figure 7 The restriction on road.

As known from the above, the utility model is a kind of multipurpose bicycle anti-theft warning device, have anti-theft alarm, night light and when bicycle bell with more than plant function, overcome many deficiencies of prior art, bring great convenience to the rider.Have compact conformation, characteristics such as easy to use.

Embodiment 1: according to the utility model device of accompanying drawing and said structure, 6 * 8 * 5 centimetres of overall dimensions, power supply are the direct current dog days, adopt mercury contact vibroswitch (17), and code switch (12) is established four groups in parallel, and circuit can adopt structure shown in Figure 7.
