Technical field
The invention belongs to smart motion fields, and in particular to a kind of energy conversion mountain bike shock-absorbing based on electromagnetic damper
Device.
Background technology
Mountain bike is to jolt complicated road conditions in order to cope with and design, and to overcome what road conditions brought to rush while riding
It hits, therefore shock absorber is just at the part of most critical on mountain bike, and damping system is then the core of entire shock absorber, direct shadow
Ring the working method and working characteristics of shock absorber.
There are many kinds of current main damping dampers, mainly relies on spring, oil pressure, the mode of air pressure.These modes
Respectively have quality, comparatively, at present most the damping system of advantage be by the way of oil pressure cooperation air pressure pattern, two resistance
Damping system assists mutually, using the lightweight of air pressure, coordinates the high controllability of oil pressure, realizes good shock-proof effect.But
There are still many problems, at present using oil circuit auxiliary by the way of, oil circuit weight is very big；And there is damping oils to need frequency

The variable damping electromagnetic damping list mainly relies on magnet exciting coil and induction coil to combine, and induction coil is excited
Power of shaking vertical tremor is acted on magnet exciting coil, and the effect of cooperative mechanical spring or air damping weakens dynamic excitation
Effect.Induced electromotive force is generated due to the change of magnetic flux in induction coil simultaneously, excites induced current, is generated in magnet exciting coil
Magnetic fields under generate Ampere force, hinder to change.Slow down relative motion, plays the effect of damping shock-absorbing.
The energy storage units are to provide electric current for the magnet exciting coil of damper first, are mainly used for of short duration storage
Energy is that the intelligent cell of shock absorber is powered.Not only energy can be obtained by damping system, can be carried out with external power supply
Charging is mainly charged using general USB.
Preferably, the energy storage units are battery.
Preferably, the intelligent switch unit includes gyroscope, microcontroller, DC-DC circuit, gyroscope and microcontroller phase
Even, energy storage units are that gyroscope and microcontroller are powered, and microcontroller is connected by DC-DC circuit with magnet exciting coil.

Specific implementation mode
The mode of the damping system just used at present, most mainstream is exactly, on the one hand using a kind of thick liquid cooperation of oil
Piston, using oil when being pressurized, because the sticky maximum speed for flowing through aperture is limited to limit the movement of piston,
Coordinate spring mechanical to act on simultaneously, achievees the effect that damping, another part are then to use gas, shape of the gas according to perfect gas
State equation, it is clear that gas will produce huge pressure when pressed volume reduces, and act on piston, hinder piston fortune
It is dynamic, realize damping.It is to have prodigious reason wherein that such pattern why can be used at present, it may be said that either
Hydraulic damping or air-pressure damping suffer from respective advantage extremely outstanding simultaneously and include disadvantage：
For oil circuit, the modulability of oil circuit is much better than air damping and (and goes the reason of gas tightness, gas chamber damping
Substantially can regard as non-adjustable), damping is presently mainly adjusted using the size for changing the small sky that liquid flows through, very
To being to close damping, such adjustment mode is not continuous enough, and adjustable range is also very limited.While it is unavoidable precisely due to big
It measures damping oil to exist, damping oil can bring prodigious weight to increase, while it is very high to need the seal of oil sealing to remain at
State needs periodically as the continuous toughness using damping oil also has oxidation in constantly change damping oil
Damping oil (replacing for general three months to half a year primary) is replaced, needs the tool oil product of profession costly with changing.
The maximum advantage in gas chamber side is light-weight, but the leakproofness of gas and stronger diffusivity, so as above
Described damping is substantially uncontrollable, damper is let alone closed, simultaneously because the relationship of the pressure of gas and volume
It is determined by the equation of gas state, so the damping linearity of the damping of gas is very low, current effect essentially consists in
Weight can significantly be mitigated.
Ideal effect is can be only achieved after the mutual supplement with each other's advantages of their both sides.But such damping system is in real work
When still there is a problem of many and huge improvable space, especially the oil amount of stressing are big, need often to safeguard and
And safeguard that expensive problem is difficult to make up.While the mechanical energy that we are generated in using damping process is essentially all
The interior energy for being converted into damping oil or restraint gas is basically to be wasted, then what method recycling machinery we have
Can, it is very simple to think it over this song problem in fact, is exactly generator from mechanical energy to electric energy, only need cutting magnetic induction line and
, if only two coils of excitation and induction can be settled, not only weight is got off, and maintenance does not need substantially,
Just having broken down repair at last also should not be too simple.Using permanent magnet, then in this case the damping of cooperation gas chamber just loses damping
The controllability of shock absorber is then changed to generate magnetic field using induction coil, in this case will obtain than original oil circuit tune
Save the adjustable range of bigger and more fine and closely woven regulating effect.The electric energy in induction coil can also be recycled simultaneously, it is real
In the riding of border road conditions, induction coil be certainly there is electric energy always, if then we become electric energy suitable for recycling, for
We will filter it for one unstable electric energy, adjust amplitude, regather electric energy, and it is intelligent parts confession to store and export electric energy
Energy.
When going up a slope, needs damper not work, to go this when to turn off damper manually, when descending
It needs damper to automatically open again, adds gyroscope, by judging the angle with ground.To react the climb and fall gradient, from
And the switch damper of intelligence, and the electric energy that the electric energy that this part intelligence original paper needs can be generated directly by electromagnetic damper Lai
It provides.
