一种集成自适应机械开关的压电能量回收装置
- Affilication of Author(s):西南交通大学
- Patent description:本发明公开了一种集成自适应机械开关的压电能量回收装置,包括支撑底座、夹具、压电悬臂梁集能器、幅值检测机构、系统接口电路和能量管理单元；集能器包括压电元件、悬臂梁、第一质量块；幅值检测机构包括开关悬臂梁、轻弹簧、第二质量块；系统接口电路分别通过导线与压电元件和能量管理单元相连,系统接口电路分别通过导线与第一质量块和轻弹簧的接触点连接。本发明采用了同步开关电感回收技术(SSHI),克服了原有电子开关需要额外的电子元件控制且消耗电能和机械开关不能适应振幅变化在幅值的正负极值处自动闭合的缺点；结构简单、可靠。
