The invention discloses a vibration energy collection device which comprises a vibration mechanical energy conversion device and a collection device. The vibration mechanical energy conversion device comprises a permanent magnet group, an upper iron core, a lower iron core, a fixed middle shaft, a coil, a spring piece, a winding support and a shell. The permanent magnet group is formed by superposing two magnets, adjacent magnet surfaces have the same polarity, a magnetic conductive gasket is arranged between the adjacent magnet surfaces, the permanent magnet group is fixed between the upper and lower iron cores, and the permanent magnet group and the upper and lower iron cores are positioned and fastened by the fixed middle shaft. A groove is formed in the outer surface of a wire mold, a conductive coil is arranged in the groove, the wire mold is fixed on the winding support, and a fixing cover and upper and lower bottom covers are arranged above and below the shell respectively. The collection device comprises a rectifying circuit, a voltage stabilizing circuit and an energy storage unit, and the collection device is placed in the shell. Vibration mechanical energy in the environment is converted into electric energy, stable direct-current voltage is output, a traditional battery power supply mode can be replaced, the trouble of frequent battery replacement is avoided, environmental pollution is reduced, use is convenient, and maintenance is not needed.
