Abstract
The utility model relates to a magnetic shock absorber, comprising a stator and a mover, which is characterized in that: two permanent discs capable of axial magnetic charging are respectively arranged in the stator and the mover, the like poles of the stator permanent magnetic disc and the mover permanent magnetic disc are axially opposite to each other in parallel, and an induction coil is arranged on the stator. While in operation, relative displacement occurs axially between the stator and the mover, and the magnetic repulsion force is just the damping force required for shock absorption; when relative displacement happens between the stator and the mover axially, induction current can be produced in the induction coil, and can be stored into an accumulator for future or direct use after rectification and voltage regulation. Meanwhile, according to Lenz law, the magnetic field of the current can impede the relative displacement between the stator and the mover, and the resistance force can also act as the damping force needed for shock absorption. The utility model has the advantages of simple structure, good shock absorption performance, environmental friendliness, and wide application range.
Description
Technical field
The utility model relates to a kind of vibration damper, particularly a kind of magnetic force vibration damper.
Background technique
Traditional vibration damper has spring and fluid damping formula.Spring utilizes its elastic recovery properties to realize vibration damping, and still, spring damping is easy to generate exciting and fatigue, also produces noise during work; The fluid damping formula is made up of the cylinder barrel of piston that has flowing hole and cooperation with it, piston by a rod member with connected by damping body, fluid (oil, gas or other flowing medium) is housed in cylinder barrel, during piston motion, fluid produces damping force to piston and realizes vibration damping by flowing hole, but this vibration damper, damping force changes limited, and also difficulty is applicable to dither, and fluid easily leaks.
Summary of the invention
The utility model designs a kind of magnetic force vibration damper, can overcome the defective of above-mentioned traditional vibration damper, vibrational energy can be converted to useful electric energy, and cost is low, non-maintaining, the life-span is long.
The utility model is realized by following technological scheme.
The utility model is made up of stator and mover, gappedly between stator and the mover does not contact.The permanent magnetism dish of axial charging all is set in stator and mover, and mover permanent magnetism dish is parallel with the axial like pole in stator permanent magnet rim relatively; At stator inductor coil is set.During the utility model work, relative displacement takes place in stator and mover vertically, and axial magnetic repulsion is exactly the damping force that vibration damping needs; Stator and mover take place vertically relative displacement the time, produce induction current at inductor coil, this electric current charges a battery or directly uses through rectifying and pressure-regulating; Simultaneously, known that by Lenz's law the magnetic field of this electric current hinders stator and mover relative displacement, obstruction power also is the damping force that vibration damping needs.Described stator and mover can be changed mutually according to practical application, and promptly stator is as mover, and mover is as stator.During use mover with connected by damping body, stator connects with fixed base.
The utility model has following advantage:
1. the utility model utilizes permanent magnetism power and magnetic force induced electricity to form damping power simultaneously, and effectiveness in vibration suppression is better, environmental protection.
2. utilize inductor coil that vibrational energy is converted to available electric energy, rather than resemble spring piston formula vibration damper or some magneto vibration damper and with friction mode vibrational energy is converted to thermal waste and falls.
3. simple in structure, the life-span is long.
