Description

Magnetically floating energy-accumulating vibration damper

The present invention slows down vibration with magnetic is floating, and vibrational energy is transferred to a kind of device of electric energy.

The shock attenuation unit of some vehicle such as current mobility car generally all is a spring leaf, though utilize spring or spring leaf can play the effect of vibration damping, the energy that vibration is produced but can not be utilized.If each automobile because the energy that vibration is produced obtains utilizing, and a medium-sized city has 1,000,000 traveling automobile so, and the energy that can utilize vibration to produce is huge, has also been saved the huge energy simultaneously when exercising.Invented magnetically floating energy-accumulating vibration damper at this purpose and meaning.This device is used for vehicle vibration damping, not only has good effect, and the transformation of energy that vibration can also be produced is an electric energy.

This invention is to utilize electromagnetic induction principle, and promptly magnet moves in screw actuator and produces the shock absorber that faradic method is designed.Theory structure is equipped with two magnet 2 and 3 that polarity is identical at the two poles of the earth of a magnet 1 shown in figure (1).Magnet 2 and 3 is fixed by center shaft 4, and this center shaft 4 passes the centre hole of magnet 1.The appearance of magnet 1 is fixed with the aluminum alloy or the hard plastic shell 9 of a non-iron.Twine four screw actuators on shell 9 respectively, wherein two screw actuators 5 and 6 are contained in the midway location of magnet 1 and magnet 2 and 3, and screw actuator 7 and 8 is contained in the outside of magnet 2 and 3.

When magnet 2 and 3 size shape are identical with magnetic force, magnet 1 will be squeezed in midway location by the magnetic force of magnet 2 and 3, equate apart from the distance of magnet 2 and 3, be made as h.On fixing shell 9, twine four screw actuators 5,6,7,8 that height is h.Screw actuator 5 and 6 is to be wrapped between magnet 1 and magnet 2 and 3, and screw actuator 7 and 8 is the outsides that are wrapped in magnet 2 and 3.When center shaft 4 stressed up-and-down movements, screw actuator 5,6,7,8 relative magnet 2 and 3 have relative motion, and the magnetic line of force in the screw actuator 5,6,7,8 is changed, and screw actuator certainly leads to inducing current.

If when four solenoidal direction of windings were identical, the faradic direction that produces was identical, therefore four screw actuators can be cascaded from beginning to end.Head and the tail two after four screw actuators are cascaded terminate in the bridge rectifier circuit 16, shown in figure (3).Bridge rectifier circuit W transfers the alternating current impression electric current that four screw actuators 5,6,7,8 are produced to direct current, passes through C then ₁And C ₂Rectification is charged through supplying with storage battery 17 after the stabilivolt D voltage stabilizing, thereby has been realized the conversion of energy of vibration to electric energy.The energy that vibration is produced is utilized.

It is fine through experiment effect to utilize the principle of two magnet homopolar-repulsions to do shock absorber.For preventing the rigid collision of two magnet, paste last two thin rubber cradles 13 and 14 at the magnet 2 of figure (1) and 3 inboard.Reduce friction with the shell 9 that is fixed on the magnet 1 in order to make the magnet 2 and 3 up-and-down movements that are fixed on the center shaft 4, in the outside of magnet 2 and 3 by antifriction-bearing box 10 is housed, adorn three or four antifriction-bearing boxs 10 at magnet 2 and 3 each outside, make the slide relative of magnet 1 and shell and center shaft 4 and magnet 2 and 3 be restricted to rolling.The heat that is sent when producing inducing current in order to leave, center shaft 4 is made hollow 15 can the conducting current.

This invention can be used as parts and uses when reality is used.Vibrating mass is fixed on the flange 12 on the magnetically floating energy-accumulating vibration damper center shaft 4, needs the buffer body of vibration damping to be fixed on the flange 11 on the shell 9.If two magnetically floating energy-accumulating vibration dampers are vertically installed, then can cushion the vibration of both direction; If the mutually vertical installation of three magnetically floating energy-accumulating vibration dampers then can be cushioned the vibration of all directions.When using this shock absorber, can carry out aggregate erection arranged side by side with a plurality of shock absorbers according to the size of supporting power.For the large-scale mechanical vibration that needs vibration damping or the vehicle, this shock absorber can be used as a basic element of character and uses.According to the difference that oscillating region requires, can make the shock absorber of magnet 1 and magnet 2 and 3 different spacing h on request.

According to a small-sized magnetically floating energy-accumulating vibration damper of above-mentioned theory structure processing and fabricating, shown in figure (2) photo.The spacing h=15mm of this shock absorber magnet 1 and magnet 2 and 3, mutual repulsive force maximum can reach 10 kilograms between magnet, adds external force with hand and acts on up and down, and sensation is as acting on the spring.The inducing current that magnet 1 and magnet 2 and 3 relative motions are produced maximum after testing can reach 150mA; Maximum power is 45mW.If use large-scale magnet, repulsive force is 200 kilograms of magnetically floating energy-accumulating vibration dampers of producing to the maximum, is equivalent to 20 this little magnetically floating energy-accumulating vibration dampers of having made, can extrapolate its maximum power and can reach 900mW.5 to 6 repulsive forces of vehicle needs of one 1000 kilopond are 200 kilograms magnetically floating energy-accumulating vibration damper, and these magnetically floating energy-accumulating vibration dampers lump together, and its power can reach 5W.Substantially can use required electric energy for its taillight.

On smooth highway during vehicle running car because the buffer action of spring leaf makes the basic held stationary of car body, in fact wheel all the time relatively car body at up-and-down movement.If each automobile all is equipped with this electromagnetism energy-accumulating vibration damper, though the electric energy that each shock absorber obtains is very little, for each car meaning and little, but if 10,000,000 cars all use this magnetically floating energy-accumulating vibration damper, add so to have 50,000 kilowatts power together, be equivalent to a power house.These instruments of travelling that magnetically floating energy-accumulating vibration damper is housed travel and just can obtain huge electric energy in one day, so this invention has important social effect for saving the energy.

This invention has not only solved the vibration damping problem of the vehicle, but also has utilized vibrational energy, has saved the huge energy with integralization zeroly.This magnetically floating energy-accumulating vibration damper damping cushion effect is good, and used main material is exactly three blocks of magnet and one group of coil, and is with low cost, simple in structure, is easy to batch manufacturing and promotes the use of.
