Seesaw type unicoil magnetic generating device

A seesaw type unicoil magnetic generating device comprises an upper soft magnetic material, a lower soft magnetic material, a permanent magnet, an iron core and a coil, wherein two ends of the permanent magnet are connected with the soft magnetic materials respectively, and two end faces of the permanent magnet are contacted with the middle ends of the soft magnetic materials to form an I-shaped magnet. The iron core penetrates through the coil and is led out of two ends of the coil to be embedded into the I-shaped magnet, and two ends of the iron core are contacted with the upper soft magnetic material and the lower soft magnetic material respectively. Relative translational mechanical energy of the permanent magnet and the iron core is converted into electric energy through the magnetic generating device, and the electric energy is supplied to micropower devices such as a remote control. The seesaw type unicoil magnetic generating device is small in size, free of pollution and simple in structure, can convert short-stroke translational mechanical energy into electric energy, and is particularly suitable for the fields of micropower collection and wireless sensor networks and the like.
