Claim Text:
1. A damper with linear power generation and reluctance, comprising: a tube body having a first through hole at an end, a second through hole at the other end, and a first axial passage formed by the first and second through holes; a hollow driving rod having an inner end and an outer end as the outer end stretching outside the first through hole and having a first pivot portion and the inner end being able to displace inside the tube body, a second axial passage formed therein, and a third through hole connecting to the second axial passage at the inner end thereof; a screw sleeve arranged in the third through hole for moving with the driving rod in linear displacement; a screw rod having thread section thereon for screwing with the screw sleeve, and a shaft section stretching out from the second axial passage of the driving rod; a driving case having a bottom casing and a top casing which form a space therein with the bottom casing having a second pivot portion and the top casing having a second hole thereon, a flange arranged around the edge of the second hole for engaging the second through hole of the tube body, and a first hole arranged on the flange for engaging a first bearing, allowing the shaft section of the screw rod to pass through into the space and the screw rod to rotate; a generator having a shaft, a stator, and a rotor where the stator has a positioning portion and a group of coil with the seating of the positioning portion being engaged through the second hole for the group of coil to be fixed outside the top casing, and the positioning portion having a second bearing arranged therein for the shaft to pass through into the space, allowing which to rotate; and the rotor having a wheel and a magnet fixed therein, both engaging the shaft for the magnet to rotate around the group of coil of the stator so as to form a generator system; a driving mechanism having a driver and a driven element connected to the driver, both of which are disposed inside the space of the driving case where the driver is engaging to an end of the shaft section to be driven thereby and rotate, and the driven element is engaging to and end of the shaft to be driven thereby and rotate; whereby the driving rod is moving in linear displacement along the first axial passage when the first and second pivot portion are driven, resulting in the screw sleeve driving the screw rod to rotate, then the driving mechanism driving the shaft and the rotor to rotate for the magnet and group of coil to produce a torque by the electromagnetic loading as the buffer and damping force for the linear displacement.
