Title:
ARRAYED ELECTROMAGNETIC-FRICTION COMPOSITE VIBRATION ENERGY COLLECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/082335
Kind Code:
A1
Abstract:
An arrayed electromagnetic-friction composite vibration energy collection device, comprising: a housing (1); and a vibration energy collection mechanism, comprising a plurality of vibration energy collection units (2) arranged in an array in the housing (1), each vibration energy collection unit (2) comprising a spring vibration pickup unit (3), an electromagnetic power generation unit (4), and a friction power generation unit (5); the spring vibration pickup unit (3) comprises a vibration pickup body (31) and a plurality of springs (32), one end of each spring (32) is connected to the outer surface of the vibration pickup body (31), and the other end is connected to the inner surface of the housing (1); the electromagnetic power generation unit (4) comprises a magnet unit (41) and a coil (42), the magnet unit (41) is provided in the vibration pickup body (31), the magnet unit (41) comprises two magnets (411) arranged opposite to one another in the vertical direction, the magnetic poles of the two magnets (411) repel one another, and the coil (42) surrounds the vibration pickup body (31) and is connected to the inner surface of the housing (1); and the friction power generation unit (5) is connected to the outer surface of the vibration pickup body (31). Vibration excitation in any direction on the outside can be converted into electric energy to be outputted; and by means of arrayed design, the working frequency band is widened.
