The invention relates to a combined type mechanical energy conversion bicycle wheel which comprises a rotating assembly and a driving assembly, the rotating assembly comprises a wheel frame, spokes and a plurality of permanent magnets, the spokes are fixed in the wheel frame in the radial direction, and the permanent magnets are fixed to the spokes; the composite conversion assembly comprises a rotary connecting piece, a plurality of piezoelectric vibrators, magnets and coils, the rotary connecting piece is rotationally connected with the wheel frame, the piezoelectric vibrators are fixed to the rotary connecting piece in the radial direction, the magnets and the coils are fixed to the piezoelectric vibrators, and the magnets and the coils are fixed to the piezoelectric vibrators. A PZT film piezoelectric layer is arranged on the surface of the piezoelectric vibrator, a long connecting rod is omitted, the occupied space is small, and reciprocating sweeping and scraping can be achieved without large-amplitude swing. The piezoelectric and magnetoelectric combined mode is adopted to collect and convert vibration energy, and compared with a single piezoelectric mode in the prior art, the energy harvesting efficiency is improved.

    本发明涉及一种复合式机械能转化自行车车轮,包括:转动组件,包括轮框、轮辐以及若干永磁体,所述轮辐沿径向固定于所述轮框内,所述永磁体固定于所述轮辐上;复合转化组件,包括转动连接件、若干压电振子、磁铁以及线圈,所述转动连接件与所述轮框转动连接,若干所述压电振子沿径向固定于所述转动连接件上,每一所述压电振子上固定有所述磁铁以及所述线圈,所述压电振子表面设置有PZT薄膜压电层,本发明省去了长连杆,占用空间小,无需大幅度摆动即可实现往复扫刮。本发明采用压电和磁电的组合模式对振动能量进行采集转化,相对于现有技术中的单一的压电方式,提高了俘能效率。
