Electricity generating shock absorbers

A method of manufacturing an electricity generating shock absorber, the method comprising:

• winding a coil at least once around a hollow tube having an electrical resistance;
• stacking a first pair of permanent magnets on a shaft having a magnetic reluctance;
• adapting the stacked shaft to be moveable in relation to a hollow cavity of the hollow tube;
• attaching the shaft to a first base;
• separating the first pair of magnets between each other on the shaft by a first magnetically-permeable spacer;
• aligning the first pair of magnets with like-poles facing each other;
• and
• encapsulating at least a part of the wound coil via a concentric outer cylinder attached at one end to the first base,
• further comprising connecting the coil to a rectifier, wherein the first pair of magnets comprises a radial magnet and an axial magnet and the cylinder is at least partially composed of a magnetically-permeable material and the first pair of magnets and the first spacer are ring-shaped;
• and
• wherein the first spacer is formed of a material having a high magnetic permeability, the inlayed annular spacer material being different than the radial magnet.

A method for generating electricity from mechanical vibrations, the method comprising:

• providing an electricity generating shock absorber having a magnet assembly including a first pair of magnets stacked horizontally along a shaft constructed of magnetic reluctant material and a coil assembly including a coil wound around a hollow tube having an electrical resistance, the first pair of magnets aligned with like-poles facing each other, the first pair of magnets, an insertion end of the magnet assembly being slidably inserted into an open end of the hollow tube of the coil assembly, a concentric outer cylinder encapsulating at least a part of the coil assembly, the cylinder attached at a base end of the magnet assembly opposite the insertion end;
• coupling a closed end of the hollow tube to a first mass;
• coupling the base end of the magnet assembly to a second mass, the electricity generating shock absorber providing vibration dampening between the first mass and the second mass;
• inducing relative motion between the magnet assembly and the coil assembly to generate electromotive voltage in the coil;
• and
• capturing the electromotive voltage,
• wherein the coil is operably connected to a rectifier, the first pair of magnets comprises a radial magnet and an axial magnet and the cylinder is at least partially composed of magnetically-permeable material and the first pair of magnets and the first spacer are annular;
• and
• wherein the radial magnet includes an inlayed annular spacer formed of a material having a high magnetic permeability, the inlayed annular spacer material being different than the radial magnet, the radial magnet and the inlayed annular spacer have combined dimensions equivalent to respective dimensions of the axial magnet.

An electricity generating shock absorber comprising:

• a first case comprising:
• a rack attached to the inner surface of the first case;
• and
• a second case comprising:
• a pinion in contact with the rack and attached to the inner surface of the second case via a first shaft mounted on a first base,
• a bevel gear box comprising a first and second bevel gear in contact with each other, the first bevel gear mounted on the first shaft, the second gear mounted on a second shaft coupled via a coupler to a rotational motor attached to the inner surface of the second case.
