Abstract

A vehicle wheel generating electric energy by utilizing vehicle pressure features that the ring-shaped magnetic steels and windings are respectively installed in the said wheel to form stator and moving element. Under the action of pressure generated when vehicle is running, the moving element moves up and down in the said stator to generate electric current. Its advantages are both functions of bearing load and damping vibration, and use of pressure to recover energy.

Description

A kind of wheel generating electricity by pressure

The present invention relates to wheel and technical field of power generation, particularly utilize the wheel of vehicle pressure electricity-generating.

At present, wheel has been the indispensable important component parts of various vehicles.It mainly consists of compositions such as wheel hub, wheel rim, tire.And tire mostly is the inflatable tire that rubber is made.Mainly load capacity and the impact that reduces to vibrate aspect purposes.In the wheel generation technology, China's patent application patent on January 8th, 1992 disclosed a kind of electric vehicle, this technology has proposed wheel is contained in the end of generator amature, rotor is worked as wheel to be used, wheel makes the device of generator for electricity generation, the generating of this technology is to come the cutting magnetic line generation by wheel, and such shortcoming is to be cost by consumed power.China's patent application patent on July 29th, 1998 disclosed a kind of wheel type pressure engine device, this technology has proposed with two minute wheels of first a, second, a big wheel axle that has several pillar stiffeners and linking a power rail is set on first minute wheel median aperture pipe, after the second minute wheel is fixed in the tail end place of power rail, to form a pressure generating set.This device leans on the pressure of vehicle when wheel rotates, and it exceeds each outer pillar stiffener of wheel, and the flexible support that does not stop is moved.Push big wheel axle and rotate and then drive generator for electricity generation.The deficiency of this technology is directly independently to use as the wheel in the vehicle, can only be installed in axletree or wheel next door as annex, and this device volume is bigger, also produces certain frictional resistance when depended on pressure contacts with ground.

The purpose of this invention is to provide and a kind ofly have carrying to utilize the novel wheel of pressure electricity-generating, another object of the present invention again with vibration damping be to change existing inflation and car wheel structure, a kind of inflation-free wheel generating electricity by pressure of new structure is provided.

For achieving the above object.The present invention is that conventional tire tyre surface central part is changed system into indent, convex shape with regard to first purpose at first, both sides are respectively charged into annular permanent-magnet material in carcass then, and be fixed as stator, central part is installed the toroid winding winding and tyre surface is fixed as mover, and the profile tyre surface central authorities of whole generating tire are convex with both sides.When vehicle ', the pressure of vehicle makes tire contact with ground, and the tread projections shape is pushed back, and drives on the mover in the tire to move, and produces cutting magnetic line and forms electric energy with stator, and tyre rotation is fast more, and then the electric energy of corresponding generation is just big more.

Another object of the present invention is such.Replace rubber tire with concavity annular inner casing and shell, its case material available metal or non-metal and synthetic material are manufactured.Inner casing combines for the form of being inserted in shell.The power generation assembly that annular magnetic steel and coil winding constitute is housed in the shell, annular magnetic steel is separately fixed at stator inner casing both sides, coil winding fixed housing central part forms mover, in order to make wheel as the air-inflation tyre antivibration, the shell inner bottom part is equipped with spring respectively, and adds auxilliary elastic rubber layer in case surface.And stator and mover motion itself in the shell also can produce the magnetic damping effectiveness in vibration suppression.When vehicle ', when wheel is contacted with ground by its gravity, can make wheel drive the shell up-and-down movement under pressure, thereby make the coil winding up-and-down movement in magnet steel in the shell produce electric current, used by the current consumer on the car.

Because the present invention has utilized this unavailable energy of vehicle pressure.So can provide each new energy to replenish to vehicle.But also can utilize magnetic damping to play effectiveness in vibration suppression.The present invention also provides a kind of new car wheel construction of inflation-free, and it can utilize pressure electricity-generating when having the conventional wheel effect, exempts from inflation again, prevents the phenomenon of blowing out.Wheel generating electricity by pressure of the present invention does not have the size restriction, so install and use applicable to various vehicles.

Below in conjunction with drawings and Examples the present invention is further described in detail:

Fig. 1 is a kind of overall structure cutaway view of pressure electricity-generating wheel of the present invention.

Fig. 2 is the tyre surface cutaway view of Fig. 1.

Fig. 3 is the overall cutaway view of the another kind of inflation-free structure of wheel generating electricity by pressure of the present invention.

Now process now is described in fact with Fig. 1, Fig. 2, at first tire 4 tyre surfaces are changed system into shape 6 as shown in Figure 1 and Figure 2, then annular permanent-magnet material such as Fig. 1,2, be respectively charged into both sides in the carcass, and be fixed as stator with fixture 5, be fixed as mover then toroid winding winding 1 concavity shape 6 places in the tire of packing into, and with tyre surface.When vehicle ', tire and ground are pushed back up tyre surface central part 6 and move under the pressure effect of its vehicle, up move thereby drive mover 1.Along with the rotation of wheel, mover 1 will not stop upper and lower motion and produces electric current in the middle of stator 2 like this, and electric current is transported on the vehicle current consumer by lead 3 and uses.

Now as shown in Figure 3, make annular concavity inner casing 7, shell 8 with metal or non-metallic material with another kind of embodiment.Inner casing 7 is fixed on the wheel hub 10 and (also can be integral inner housing and wheel hub), both sides are loaded onto annular magnetic steel 2 respectively in inner casing 7, and be fixed as stator, there is spring 13 centre, load onto toroid winding winding 1 in shell 8 central interior positions, and be fixed as mover, two side bottoms are equipped with spring 9, then shell 8 is enclosed within on the inner casing 7, again seal ring 11 is placed in both sides respectively.Set up sliding pin 12, shell 8 outside faces are assisted rubber layer 14, like this when vehicle ', the pressure of vehicle is pushed back up wheel shell 8 and moves, the coil winding 1 that drives in the shell is up moved, along with the not stall of wheel is moving, the coil winding 1 in its shell is not stopped upper and lower motion and is produced electric current in magnet steel 2, and electric current is transported on the vehicle current consumer by lead 3 and uses.

The present invention does not limit to above-mentioned two kinds of versions, be equally applicable to other version, need only the power generation assembly that magnet steel and coil winding formation are installed at inside wheel, when vehicle ', utilize the pressure effect to make stator and mover motion generation electric current in the wheel all belong to the scope of the invention.
