Background technique
Now with the elastic force of magnet magnetic force as vibration damper; Be fixing motionless magnet in the vibration damper bottom; Fixing moving magnet that is synchronized with the movement with piston on piston, the magnetic pole of these two strong magnets is that same pole is relative, with the elastic force of the relative repulsive force of same pole as vibration damper.Because the magnetic force of permanent magnet is generally less, just with the volume that increases motionless magnet and moving magnet, the area that increases the opposing side of these two magnets satisfies the elastic force of vibration damper needs.Its shortcoming is to make the weight of vibration damper too big, and the cross section of vibration damper is big too, and the consumption material is many, cost is high and the shortage practicability.As use one group of diameter be 3.0 centimetres neodymium iron boron magnetic body as the elastic member of the vibration damper of electric bicycle, the stroke of vibration damper also has only 2.0-3.0 centimetre; As use one group of diameter be 10.0 centimetres ferrimagnet as the elastic member of the vibration damper of electric bicycle, the stroke of vibration damper also has only 2.0-4.0 centimetre, not only volume is big, weight is big, cost is high, stroke is also too short, does not have the flexibility of damping.
For overcoming the magnetic force deficiency of permanent magnet; Have the human electromagnet as the elastic member of vibration damper to increase magnetic force; But its shortcoming is: the electric energy of the battery that carries on the vehicle is to change; Then the magnetic force of electromagnet changes, and causing the damping of vibration damper is the power change with battery really, i.e. the damping of vibration damper fruit is unstable.For preventing that battery from can not supply power, also need additional springs as spare unit, this vibration damper complex structure, poor stability.
The model utility content
The purpose of the utility model provide a kind of simple in structure, cross section is little, in light weight, with two permanent magnets with the repulsive force between magnetic pole as elastic force; And can be when the reciprocating work with vibration damper; Consume a high proportion of electric energy that is recycled into of mechanical energy, have the vibration damper of damping and amortization again.
The structure of the utility model is:
Can improve the vibration damper of generating efficiency in the damping working state with levitated magnet; Comprise body 1, body 1 one end internal fixation have location permanent magnet 2, are provided with piston mobile 3 in body 1 the other end; Adjacent that of piston 3 and location permanent magnet 2 simultaneously is fixed with piston permanent magnet 4; It is characterized in that: two-layer inside and outside body 1 is divided into, internal layer is a pipe 5 in the nonmagnetic substance, and skin is a rigidity bearing tube 6; Manage in 5 in the nonmagnetic substance between location permanent magnet 2 and piston permanent magnet 4; At least be provided with one and location permanent magnet 2 and all discontiguous suspension permanent magnet 8 of piston permanent magnet 4; Suspension permanent magnet 8 is relative with magnetic pole with the adjacent surface of location permanent magnet 2; Suspension permanent magnet 8 is relative with magnetic pole with the adjacent surface of piston permanent magnet 4, and the adjacent surface between the adjacent difference suspension permanent magnet 8 is relative with magnetic pole; Suspension permanent magnet 8 along body 1 longitudinally thickness reach suspension permanent magnet 8 at least and in nonmagnetic substance, manage the 5 needed thickness that can not overturn;
Pipe 5 is provided with a power coil 10 with outer in the mezzanine space 11 of rigidity bearing tube 6 at least in the nonmagnetic substance of body 1, and power coil 10 is in unloaded state is located the mezzanine space 11 of section between permanent magnet 2 and the piston permanent magnet 4; 10 of power coil be one around to, the ring surface of power coil 10 every circle coils is vertical with body 1 center line;
Suspension permanent magnet 8 one or two magnetic pole strengths are provided with and close and circuit coil 9, on 8 one magnetic pole strengths of suspension permanent magnet close with 9 of circuit coils be one around to, promptly only be clockwise direction around or only be counterclockwise direction around; Close vertical with body 1 center line with the ring surface of circuit coil 9 every circle coils.
If location permanent magnet 2, piston permanent magnet 4 are that quality is the same and big or small identical with suspension permanent magnet 8; As between location permanent magnet 2 and piston permanent magnet 4, a suspension permanent magnet 8 being arranged; Two magnet clearance spaces are then arranged, and this has the vibration damper of suspension permanent magnet just to be equivalent to two supporting power and running lengths of having only the no suspension permanent magnet vibration damper of location permanent magnet 2 and piston permanent magnet 4.Constant like supporting power, then there is each magnet cross sectional area of the vibration damper of suspension permanent magnet almost to need only the half the of no each magnet cross section of suspension permanent magnet vibration damper.So bear under the weight condition, there is the vibration damper of levitated magnet can significantly reduce the cross section of permanent magnet, increase stroke, also make vibration damper do very for a short time.
For location permanent magnet 2, piston permanent magnet 4 and suspension permanent magnet 8, the pole polarity of the adjacent surface of any adjacent magnets or title opposing side is identical, and promptly the South Pole is to the South Pole, and the arctic is to the arctic.The repulsive force of the identical generation of pole polarity of this opposing side also is the power that suspension permanent magnet 8 can be suspended just as the elastic force of vibration damper.
Use nonmagnetic substance with pipe in the vibration damper that magnet directly contacts; There is not magnetic attraction when making piston permanent magnet 4 and suspension permanent magnet 8 in nonmagnetic substance, manage in 5 to-and-fro motion and between the interior pipe; Do not influence reciprocating sensitivity; Particularly the friction between magnet and the interior pipe can be very little, and increased the serviceability of vibration damper.
No matter suspension permanent magnet 8 is any shape, and pipe can not overturn in 5 in nonmagnetic substance, is same pole otherwise suspension permanent magnet 8 just can not keep the adjacent surface with adjacent magnets.In nonmagnetic substance, manage upset in 5 for the permanent magnet 8 that prevents to suspend, suspension permanent magnet 8 can not be a thin slice, and certain thickness should be arranged, and will reach the degree that suspension permanent magnet 8 can not be overturn along the thickness of pipe 5 central shafts in the nonmagnetic substance.The thickness of general suspension permanent magnet 8 should be maximum wide by 1/6 greater than pipe in the nonmagnetic substance 5.
Can be when the reciprocating work with vibration damper; Consume the partially recycled one-tenth electric energy of mechanical energy principle be: when piston permanent magnet 4 and suspension permanent magnet 8 are managed in 5 to-and-fro motion in nonmagnetic substance; The power coil 10 of the interval cross section scope of movement travel produces the magnetic line of force of cutting piston permanent magnet 4 or suspension permanent magnet 8 and produces induced electromotive force or claim induced voltage, promptly produces the generating effect.A plurality of power coils 10 are preferably arranged; Each power coil 10 is managed 5 outer walls in nonmagnetic substance extreme length a preferably is no more than piston 3 average shortest route in working order; Guaranteeing piston 3 when the general work state, each piston permanent magnet 4 and suspension permanent magnet 8 make the magnetic line of force of the magnet of cutting that a power coil 10 can be complete respectively at least.
Close and be achieved in that with functions that circuit coil 9 is regulated damping and amortizations automatically same to close the magnetic line of force that closes with circuit coil 9 acquisition induced current with circuit coil 9 every circles all be same direction owing to close vertically with body 1 center line with the ring surface of circuit coil 9 every circle coils.Be pressed towards the bottom direction of vibration damper when shock absorber piston 3; Suspension permanent magnet 8 also is pressed towards the bottom direction motion; The magnetic flux that closes with circuit coil 9 that is fixed on piston permanent magnet 4 and suspension permanent magnet 8 a certain magnetic poles changes; Make and close and the circuit coil 9 interior induced current that produce, the magnetic field magnetic force that this induced current produced always hinders the motion of piston permanent magnet 4 and suspension permanent magnet 8, promptly produces damping function.That is to say; When shock absorber piston 3 is pressed towards bottom direction; Close with circuit coil 9 and just produce the damping magnetic force that stops piston 3 to be pressed towards bottom direction automatically; It is fast more that piston 3 is pressed towards the movement velocity of bottom direction, and it is also big more to close the induced current that produces with circuit coil 9, and the damping magnetic force that produces automatically is big more.When shock absorber piston 3 resiliences away from bottom direction; Close with circuit coil 9 and produce a back current again; The magnetic force that back current produces hinders shock absorber piston 3 resiliences again, and piston 3 return speed are slowed down, and closes the effect that the magnetic force that produces with circuit coil 9 has damping piston 3 returning quicklies again.So close with circuit coil 9 and always produce magnetic force prevention piston 3 motions opposite with piston 3 moving direction; And piston 3 motions are fast more; This damping magnetic force is strong more; This just can make piston 3 to-and-fro motion all flexible more and steady, reduces vibrations, and this vibration damper is used for vehicle damping makes the people who takes more comfortable.
Close the reason that all produces damping function with 9 pairs of pistons reciprocating 3 of circuit coil with the physics explanation below: Faraday's law----electromagnetic induction produces the size of induction electromotive force, is directly proportional with the flux change rate of interlinkage.Be E=-n ΔΦ/Δ t.In the formula, n is a number of inductive coil turns, in the Δ t time during magnetic flux change Δ ф; The electromotive force that produces is e; The meaning of negative sign "-" is in the formula, and each other during the magnetic flux change of interlinkage, coil produces the direction of electromotive force always towards the direction that hinders flux change.And when the magnetic flux increase of mutual interlinkage perhaps reduced, the electromotive force that is produced was in the opposite direction.So the electromotive force that produces with circuit coil 9 that closes in the utility model always hinders piston 3 motions, promptly produces damping function.
Close the meaning that produces damping and amortization with circuit coil 9: for the vehicle that the damping and amortization vibration damper is arranged, the comfortable feel that the people rides in the vehicle is better.And close with 9 of circuit coils and what of the number of turn can regulate damping constant around, regulate damping constant around the number of turn and can make vibration damper and have the damping and amortization that comfortable feel needs through changing coil institute, can make power coil 10 produce maximum electric energy again and export.For this reason, can be inequality for closing of diverse location and 9 of circuit coils around the number of turn, just closing with circuit coil 9 of diverse location has different damping constants.Generally should be: few around the number of turn near closing of piston 3 directions and 9 of circuit coils; Damping constant is less relatively; Make piston 3 fast to the movement velocitys of location permanent magnet 2 directions at first like this, as much as possible be converted into the electric energy in the power coil 10 to piston 3 mechanical energy; Many around the number of turn away from closing with 9 of circuit coils of piston 3 directions, damping constant is relatively large, and the movement velocity when making the more approaching location of piston 3 permanent magnet 2 is slow more, finally stops to move downward, thereby places restrictions on the range of piston 3.
The adjacent pole face of piston permanent magnet 4 and suspension permanent magnet 8 is provided with and closes and circuit coil 9, or the adjacent pole face of location permanent magnet 2 and suspension permanent magnet 8 is provided with and closes and circuit coil 9; One close with 9 of circuit coils be one around to, promptly only be clockwise direction around or only be counterclockwise direction around; Close vertical with body 1 center line with the ring surface of circuit coil 9 every circle coils.Close and circuit coil 9 at piston permanent magnet 4 or can establishing of permanent magnet 2 of location to suspension permanent magnet 8 magnetic pole strengths; Vertical with body 1 center line with the ring surface of circuit coil 9 every circle coils owing to closing, making every circle close the magnetic line of force that obtains induced current with circuit coil 9 all is same direction.Then this closes the principle that produces piston 3 damping functions with circuit coil 9 and is same as the principle that produces damping function with circuit coil 9 of closing on the above-mentioned suspension permanent magnet 8.
Be provided with suspension permanent magnet 8 magnetic pole strengths that close with circuit coil 9 and be and cave inward that to close piston permanent magnet 4 magnetic pole strengths with circuit coil 9 be the structure or be provided with location permanent magnet 2 magnetic pole strengths that close with circuit coil 9 and be the structure that caves inward of caving inward for structure or be provided with; Close with circuit coil 9 and be embedded in the depression; Close with 9 of circuit coils be one around to, promptly only be clockwise direction around or only be counterclockwise direction around; Close vertical with body 1 center line with the ring surface of circuit coil 9 every circle coils.
