Abstract:
1. A generating device, comprising: a housing having an inner portion formed with a receiving space; a coil assembly mounted in the receiving space of the housing; and a core assembly movably mounted in the receiving space of the housing and movable relative to the coil assembly to produce a magnetic interaction between the core assembly and the coil assembly; wherein the coil assembly includes: a hollow coil seat mounted in the receiving space of the housing; a plurality of upright mounting tubes mounted in the coil seat; and a plurality of induction coil sets mounted on each of the mounting tubes and received in the coil seat; the core assembly includes: a plurality of upright cores movably mounted in the mounting tubes of the coil assembly respectively and aligning with the induction coil sets on each of the mounting tubes; a plurality of magnetic disks mounted on each of the cores to move in concert with each of the cores and movable to pass through the induction coil sets on each of the mounting tubes to produce a magnetic interaction between the magnetic disks of the core assembly and the induction coil sets of the coil assembly; an upper stop plate movably mounted in the receiving space of the housing and connected with upper ends of the cores to move the cores; and a driven piece located outside of the housing and connected with the upper stop plate to move the upper stop plate; wherein the generating device further comprises: a first strong magnet mounted in the receiving space of the housing and abutting a bottom of the housing; the core assembly further includes: a lower stop plate movably mounted in the receiving space of the housing and connected with lower ends of the cores to move in concert with the cores; a second strong magnet mounted on a bottom of the lower stop plate to move in concert with the lower stop plate and located above and spaced from the first strong magnet; wherein the first strong magnet and the second strong magnet of the core assembly have a polarity configuration to produce a repulsive force between the second strong magnet of the core assembly and the first strong magnet when the second strong magnet of the core assembly is movable toward the first strong magnet.
