Description

1. object of the invention, field of use

The present invention relates to a system for electrical energy generation and supply, in particular for mobile communication systems, and according to the invention the rolling movement of rollers 30 , for example in rolling cases, used for energy generation by using bar magnets 31 are integrated in the roles and on the frame 51 , Housing one or more coils 30 , to convert the magnetic field change into an electrical voltage or electrical current. The energy at the end of the coil 41 . 42 can be temporarily stored, processed or used directly for the energy supply of communication systems.

2. State of the art

Such power generation systems are known to be achieved with generators. The mechanical is converted Work in electrical energy.

The most important part of an electricity generator is next to the rotating armature, a static magnetic field.

The magnetic field is created by field magnets generated. Usually these are electromagnets that are attached to the inner circumference of the generator housing and be excited by direct current. The anchor, an iron core, the provided with a series of electrically conductive wire windings is rotated by mechanical force, so that the wire windings cut through a magnetic field, this creates an electrical one Electricity.

The current is from the rotating anchor, the collector, with the help of brushes decreased.

There is also, as in the published patent application DE10044490A1 (here font A) an energy generation system in which rotating coils, induction coils are guided past static permanent magnet arrangements.

The same applies to the published patent application DE19925765A1 (here font B) describes a brushless external rotor generator.

2.1 disadvantage of the stand of the technique

A disadvantage of the known methods and on the letter A, however, is that the rotating anchor with is provided with a coil and passes through a constant magnetic field.

In one case the system requires brushing or Pantographs. Due to the rotation, the pantograph wears out materially through abrasion or through oxidation of the contact surface, which in turn changes into electrical Parameters e.g. in contact resistance, has a negative impact.

In the one described in Scripture A. and in any conventional dynamo-based solution, an induction coil rotates around an axis, or in writing B a permanent magnet arrangement. The dynamo system needs one for this Axle that is not fully integrated and therefore under excessive stress, e.g. through increased Weights like an overloaded one Trolley, wear out. This leads to other about breaks and knocked out bearings.

Furthermore, especially with one mobile energy supply for the current mobility, Robustness and thus service and repair friendliness increased technical requirement required, resulting in increased costs reflects.

Rotating bodies are also included other mechanical and simultaneous electrical functions, known Weak points in technical systems. So the rotating one wears out Coil generator quickly at weak points like pantographs, through excessive turning power and Environmental conditions, e.g. when rolling fast, running with one Trolley case, when used in extreme cold, heat, dirt and mechanical forces.

Such problems can arise with the systems known today occur at any time.

3. Task, presentation the invention

Object of the present invention is a device To create a system that enables energy supply for mobile systems e.g. in business Tourist traffic that is mobility support works robustly in use and is almost maintenance-free and wear-free.

This task is done by a system solved according to claim 1.

4. Solution of the task, presentation the invention

The underlying idea of the invention it is that is contrary to the general power generation systems not the electrically conductive coil rotates, but the magnetic field in the rotating wheel around the electrically conductive coil. The rotating magnetic field can be beneficial in a rotating wheel integrated, embedded, the coil being integrated in the housing body is.

5. Advantages of the invention

In contrast to conventional systems (see 2 ) has the system according to the invention (see 1 ) the advantage that mechanically disturbing effects on the functionality of the energy generation are irrelevant.

This is shown by the fact that no mechanical wear for the functionality of power generation is present, e.g. no mechanically wearing brushes or oxidizing pantographs are present because of a fixed current and voltage decrease at the Coil is present.

Next is the electrically conductive Coil, at the coil end of the current; Tension is removed before mechanical damage, environmental influences protected, since the now rigid, non-rotating coil body is in the sheathing of the transport device is integrated, especially when it is electrically good insulating Fabrics such as plastic, rubber.

Furthermore, the shaft, anchor can be subjected to higher loads be because the bobbin not like conventional ones Systems located on this. This leads to a maintenance free Use.

Furthermore, this arrangement the integrity the magnetic body, Bar magnets in the running mass of the wheel, optimally protected. Even breaks the Bar magnets, due to external influences on the bars, e.g. excessive loads, have no negative impact on the energy generation system, in Contrary to conventional Power generation systems.

In another embodiment, a system for generating an electronic short circuit of the coil, becomes a counteracting magnetic field Braking effect on the shaft exploited.

This can be used for braking on a downhill gradient e.g. For a transport device, Suitcase that is a top speed on the slope do not exceed should.

So this can be solved especially by that when exceeded a rolling speed, the proportionally generated tension, as Triggering is exploited. When the peak voltage, trigger voltage, Triggering is about control electronics produce a short circuit at the coil end of the coil body. This creates a counter magnetic field of the coil and a Braking effect on the shaft occurs automatically.

Further advantages of the invention lie in that is a mechanical actuation a device, e.g. which is used to control the cursor, in addition to the invention Energy supply can be used. Is on the personal computer (PC) e.g. using a computer mouse, joystick, the cursor on controlled the screen, according to the invention can simultaneously the movement the ball can be used to power the computer mouse especially if it is wireless, radio-operated.
