| 按键开关用的发电机可将按键动作转为电能，为无线按键开关提供电能，在绿色智能家居中有重要的应用价值。本文提出了一种利用电磁原理的冲击式发电机，设计了一种双稳态转换的结构，在两个稳态转换的过程中，线圈中磁力线反向突变，产生电动势脉冲。采用有限元软件对双稳态结构的磁场分布情况进行了分析，对线圈和铁芯尺寸进行了优化设计，结果表明两个稳定状态的线圈中磁力线方向相反，感应电动势基本上随尺寸线性增加。加工组装了发电机样机，通过实验研究发现，按压一次，发电机输出电压可以达到30 V，产生电能达到1 469 μJ。利用电磁转换原理将按压动作转化为电能，其紧凑的设计、小巧的体积和高输出功率使其具有显著的优势，有望为无线传感网络节点和无线开关提供充足的能源，实现绿色自给运行。 |

| The switch pressing generator can convert pressing actions into electrical energy, supplying power for wireless key switches, which holds significant application value in green smart homes. This paper introduces an electromagnetic principal impact generator and proposes a bistable conversion structure. During the two steady-state transfers, the magnetic field lines in the coil undergo sudden changes in the opposite direction and the coil generates induced electromotive force pulses. Finite element software was employed to analyze the magnetic field distribution of the bistable structure, and the dimensions of the coils and iron core were optimized accordingly. The results show that the magnetic field lines in the two stable states of the coils have opposite directions, and the induced electromotive force increases almost linearly with the dimensions size. A prototype generator was fabricated and assembled. Experimental analysis reveals that the generator can produce an output voltage of up to 30 V, generating an electrical energy of 1 469 μJ. This provides sufficient power supply for wireless sensor network nodes and wireless switches, enabling green and environmentally friendly self-sufficient operation. |
