A novel broadband wind-induced vibration piezoelectric energy collector is composed of a movement input acceleration module, a movement output conversion module and an energy collecting module. The movement input acceleration module is composed of a fan, an input shaft, a bearing A, an inner engagement small gear, a bearing B, a bearing D, a flat key A, a flat key B, a bolt, a shell, a bearing C and a planetary gear train. The movement output conversion module is composed of an output shaft, an inclined disc, a bearing E, a linear bearing, a central base bent rod, a slide rod and a connection rod. The energy collecting module is composed of a base block, a cantilever beam and a piezoelectric patch. The working process of the broadband wind-induced vibration piezoelectric energy collector includes the steps that a broadband wind-induced vibration piezoelectric vibration energy collector is assembled; and secondly, the fan is blown by natural wind, rotation movement is transmitted to the planetary gear train in the movement input acceleration module, and at the same time, the movement output conversion module and the energy collecting module do corresponding movement. The broadband wind-induced vibration piezoelectric energy collector overcomes the defect that by means of existing design, wind energy in the low-speed state with unceasingly-changing wind speed cannot be effectively collected.
