Piezoelectric-electromagnetic type self-powered road floor
The invention discloses a piezoelectric-electromagnetic type self-energized road floor, belongs to the technical field of energy harvesting, and solves the problems that an existing energy harvesting floor is high in manufacturing cost, single in function, low in energy harvesting and the like. The floor moves downwards through the guide columns and the springs, and movement displacement is limited by the limiting columns. The floor is connected with a screw rod, the screw rod is matched with a spiral groove in the sleeve, and downward movement of the screw rod is converted into rotation movement of the sleeve; the rotating magnet is installed on the sleeve, the sleeve is installed in an inner hole of the bearing, and the bearing is fixed to the bottom plate. The sleeve rotates to drive the rotating magnet to rotate, so that magnetic induction lines of the coil are cut, and voltage is output. The fixed magnet is installed on the floor, the movable magnet is fixed to the tail end of the cantilever plate, the floor moves downwards, the cantilever plate is driven by magnetic force to be bent and deformed, and therefore the piezoelectric plate outputs voltage. By means of rotating motion of the screw rod and the sleeve and indirect excitation of the movable magnet and the fixed magnet, the device is simple in structure, low in manufacturing cost and good in stability; piezoelectric-electromagnetic composite energy harvesting is adopted, different energy harvesting advantages are integrated, the harvesting performance is improved, and the device can be widely applied to urban roads or smart parking lots.
一种压电‑电磁式自供能道路地板，属于俘能技术领域，解决现有俘能地板存在制作成本高、功能单一、俘获能量低等问题。地板通过导向柱和弹簧向下运动，由限位柱限制运动位移；地板连接螺旋杆，螺旋杆和套筒内的螺旋槽配合，螺旋杆向下移动，转化为套筒的旋转运动；旋转磁铁安装在套筒上，套筒安装在轴承内孔中，轴承固定在底板上；套筒旋转，带动旋转磁铁旋转，从而切割线圈的磁感线，输出电压；固定磁铁安装在地板上，活动磁铁固定在悬臂板的末端，地板向下运动，磁力驱动悬臂板发生弯曲变形，从而使压电片输出电压。本发明利用螺旋杆与套筒的旋转运动以及活动磁铁与固定磁铁的间接激励，具有结构简单，制作成本低，稳定性好；采用压电‑电磁式复合俘能，整合不同俘能优势，提高俘获性能，可广泛应用在城市道路或智慧停车场中。
