本发明的一个优选实施例中，选用5.5V电压500mA电流的三相交流无刷发电机，锂电池选用带恒流充电装置的3.6V单节锂离子电池，可以设定1C-4C向手电筒内部锂电池充电，同时采用绑定带有灯光控制和报警声的IC，使一种带声光报警的自发电手电筒功能强，成本低。In a preferred embodiment of the present invention, a three-phase AC brushless generator with a voltage of 5.5V and a current of 500mA is selected, the lithium battery is a 3.6V single-cell lithium-ion battery with a constant current charging device, and 1C-4C can be set to the inside of the flashlight. The lithium battery is charged, and an IC with light control and alarm sound is used at the same time, so that a self-generating flashlight with sound and light alarm has strong functions and low cost.

如图1所示，一种带声光报警的自发电手电筒主要有以下部分组成：手摇充电模块1、外部电源充电模块2、锂电池模块3、低电压检测模块4、照明模块5、声光报警模块6及功能选择开关7。As shown in Figure 1, a self-generating flashlight with sound and light alarm mainly consists of the following parts:manual charging module 1, externalpower charging module 2,lithium battery module 3, lowvoltage detection module 4,lighting module 5, soundLight alarm module 6 andfunction selection switch 7.

如图2所示，其中，声光报警模块6主要有以下部分组成：声光时序芯片13、发声模块14、报警允许开关16、报警LED阵列17、电阻15及电阻20。As shown in FIG. 2 , the acousto-optic alarm module 6 mainly consists of the following parts: an acousto-optic timing chip 13 , asound module 14 , analarm permission switch 16 , analarm LED array 17 , aresistor 15 and aresistor 20 .

本手电筒具有手摇自发电及外部电源充电功能。可任选一种方式对手电筒充电。This flashlight has the functions of manual self-generating and external power charging. You can choose one way to charge the flashlight.

由图1可知，手摇自发电模块1对锂电池模块3进行充电时，手摇自发电模块1--二极管9--锂电池模块3--外部地11--手摇自发电模块1构成充电回路，此时二极管8防止对外部电源模块影响或损坏。It can be seen from Figure 1 that when the hand-operated self-generating module 1 charges thelithium battery module 3, the hand-operated self-generating module 1--the diode 9--thelithium battery module 3--theexternal ground 11--the hand-operated self-generating module 1 constitutes The charging circuit, at this time, thediode 8 prevents the external power supply module from being affected or damaged.

使用外部电源对锂电池模块3充电，此时外部电源模块2--二极管8--锂电池模块3--外部电源模块2构成充电回路，此时二极管9防止对手摇充电模块造成影响或损坏。Use an external power supply to charge thelithium battery module 3. At this time, the externalpower supply module 2--diode 8--thelithium battery module 3--the externalpower supply module 2 form a charging circuit. At this time, the diode 9 prevents the hand-cranked charging module from being affected or damaged.

低电压检测模块4检测锂电池输出端电压，当低于门限值后，电压检测模块断开外部地11与内部地12之间的连接，锂电池模块3和照明模块5、声光报警模块6之间构不成回路，达到切断电路的目的，来防止电池过量放电，保护锂电池。The low-voltage detection module 4 detects the output terminal voltage of the lithium battery. When it is lower than the threshold value, the voltage detection module disconnects the connection between theexternal ground 11 and theinternal ground 12. Thelithium battery module 3, thelighting module 5, and the sound andlight alarm module 6 can not form a circuit, to achieve the purpose of cutting off the circuit, to prevent the battery from over-discharging and protect the lithium battery.

由图2可知，当功能选择开关7选择触点c时，即选择照明功能，此时，发光LED阵列19发光。It can be known from FIG. 2 that when thefunction selection switch 7 selects the contact c, that is, the lighting function is selected, and at this time, the light-emittingLED array 19 emits light.

当报警时序芯片13的TG脚受脉冲电平触发，会在LED和VO引脚分别产生定制的脉冲序列。因此，在报警使能开关16闭合前提下，功能选择开关7选择触点a，即选择报警功能时，此时会在报警时序芯片13的TG脚产生高电平脉冲，从报警时序芯片13的LED脚输出脉冲序列使报警LED阵列发出耀眼的闪烁灯光，从报警时序芯片13的VO脚输出的脉冲序列信号，送到发声模块14，经过处理及放大后，扬声器会发出尖利的报警声，从而实现声光报警功能。When the TG pin of thealarm timing chip 13 is triggered by the pulse level, a customized pulse sequence will be generated on the LED and VO pins respectively. Therefore, under the premise that thealarm enabling switch 16 is closed, thefunction selection switch 7 selects the contact a, that is, when the alarm function is selected, a high-level pulse will be generated at the TG pin of thealarm timing chip 13, and from thealarm timing chip 13. The pulse sequence output by the LED pin makes the alarm LED array emit dazzling flashing lights, and the pulse sequence signal output from the VO pin of thealarm timing chip 13 is sent to thesound module 14. After processing and amplification, the speaker will emit a sharp alarm sound, thereby Realize sound and light alarm function.
