Multidimensional vibration energy collector capable of realizing non-contact excitement

Abstract

The invention relates to a multidimensional vibration energy collector capable of realizing non-contact excitement, and belongs to the technical field of new energy and electrical generation. Connecting seats are respectively arranged on an upper top surface and a lower bottom surface of a shell body, and are used for fixing piezoelectric vibrators, and the piezoelectric vibrators are fixed on the connecting seats through screws; each piezoelectric vibrator is formed by adhering a metal substrate and a piezoelectric wafer, and a magnet is arranged at an end part of the piezoelectric vibrator; a tension spring is arranged on the upper top surface of the shell body, a pressure spring is arranged on the lower bottom surface of the shell body, the other ends of the tension spring and the pressure spring are respectively connected with mass blocks, and magnets are embedded around the mass blocks; and the magnets at end parts of the piezoelectric vibrators and the magnets embedded on the mass blocks are arranged in such a manner that homopolar magnet poles are opposite to each other. The multidimensional vibration energy collector capable of realizing non-contact excitement has the advantage that low-frequency and large-amplitude vibration energy in any direction can be collected.
