The invention relates to a train vibration energy recovery based power generator for mobile phone charging and belongs to the technical field of new energy sources and power generation. An upper cover, a casing and a base are connected through screws, a first piezoelectric vibrator is arranged and clamped between the upper cover and the casing, a second piezoelectric vibrator is arranged and clamped between the casing and the base, a ball pin sleeve is arranged on the upper cover, a ball pin is arranged in the ball pin sleeve, a screw rod is arranged on the ball pin, a first spring, an inertia block and a second spring are sequentially sheathed on the screw rod, an annular magnet is arranged on the inertia block, the free ends of the piezoelectric vibrators are provided with magnets, and the magnets arranged at the end parts of the piezoelectric vibrators are arranged in a way of approaching to the similar magnetic pole of the annular magnet arranged on the inertia block. The train vibration energy recovery based power generator has the advantage that the low-frequency and great-amplitude vibration energy recovery in any direction can be realized.
Description
technical field [0001] The invention belongs to the technical field of new energy and power generation, and in particular relates to a micro generator for recovering vibration energy, which is used for real-time charging of portable micro-power electronic products such as mobile phones. Background technique [0002] Mobile phones have become an indispensable portable communication tool in modern life. While enjoying the convenience of communication brought by mobile phones, people usually also need to face the helplessness brought about by the depletion of battery energy, especially on long-distance trains. Although modern train carriages are equipped with 220V power sockets, these power sockets do not actually supply power for the sake of driving safety and avoiding fires caused by improper use of electricity. Therefore, long-distance passengers often suffer from the problem of running out of power for their mobile phones, and the portable micro power generation device ...
