According to the electric bicycle electronic horn with the electrical waterproof function, a single-chip microcomputer collects switch state signals of K1 under the condition that a power source is powered on after a whole bicycle is locked, the single-chip microcomputer controls an NMOS switch to drive a transformer primary coil switch to store energy according to the collected signals, and a transformer secondary side drives vibration energy release of the horn after boosting conversion. The electric bicycle electronic horn with the electrical waterproof function has the beneficial effects that in order to achieve the waterproof function of a horn switch, a power supply and a control signal of the electronic horn are separately connected to achieve the waterproof function, and the switching signal for controlling the horn is directly collected by the single-chip microcomputer through the current-limiting resistor and the triode; and through reasonable parameter matching, the switching signal has waterproof capability, the situation that the loudspeaker rings by mistake or fails after raining is avoided, and stable and reliable use experience is brought to a user.
本发明提供了一种具有电气防水功能电动自行车用电子喇叭,单片机在整车锁后电源上电情况下采集K1的开关状态信号,单片机根据采集到的信号控制NMOS开关驱动变压器初级线圈开关储能,变压器次级经过升压转换后驱动喇叭的振动释能。本发明有益效果:一种具有电气防水功能电动自行车用电子喇叭,为了达到喇叭开关防水功能本方案将电子喇叭的电源和控制信号分开连接来实现防水功能,控制喇叭的开关信号通过限流电阻和三极管直接被单片机采集,通过合理的参数匹配使其开关信号具备防水能力,不会出现淋雨后喇叭错误鸣响或者失灵等情况,给用户带来稳定可靠的使用体验。
