Abstract
A shock absorber includes a cylinder including a shock-absorbing surface configured to relieve an impact of an object, a piston rod including a first end receiving the object and, in response to the impact of the object, movably inserted into an inner space of the cylinder in an axial direction of the cylinder, a magnet installed at a second end of the piston rod opposite to the first end of the piston rod to be moved together with the piston rod, an electromagnet coil configured to generate a repulsive force against the magnet, and a sensor configured to detect the magnet and cause the electromagnet coil to receive a current from a power source.
Claims20
A shock absorber comprising:
- a cylinder including a shock-absorbing surface configured to relieve an impact of an object,
- wherein the shock-absorbing surface is a slanted surface slanted with respect to a first radial direction of the cylinder substantially perpendicular to an axial direction of the cylinder;
- a piston rod including a first end receiving the object and, in response to the impact of the object, movably inserted into an inner space of the cylinder in the axial direction of the cylinder through the slanted surface, wherein the piston rod moves with respect to the slanted surface;
- a magnet installed at a second end of the piston rod opposite to the first end of the piston rod to be moved together with the piston rod;
- an electromagnet coil configured to generate a repulsive force against the magnet;
- and
- a sensor disposed at the inner space of the cylinder and configured to detect the magnet and cause the electromagnet coil to receive a current from a power source.

- a cylinder including:
- a slanted shock-absorbing surface configured to relieve an impact of an object, wherein the slanted shock-absorbing surface is a slanted surface slanted with respect to a first radial direction of the cylinder substantially perpendicular to an axial direction of the cylinder;
- and
- a stopper formed at the slanted shock-absorbing surface to prevent the object from departing from the slanted shock-absorbing surface;
- a piston rod including a first end receiving the object and, in response to the impact of the object, movably inserted into an inner space of the cylinder in the axial direction of the cylinder through the slanted surface, wherein the piston rod moves with respect to the slanted surface;
- a shock-absorbing member attached to the first end of the piston rod;
- a magnet installed at a second end of the piston rod opposite to the first end of the piston rod to be moved together with the piston rod;
- an electromagnet coil configured to generate a repulsive force against the magnet;
- and
