Description

System for Enerαieerzeuαunα for mobile communication devices

1. Subject of the invention, field of application

The present invention relates to a system for electrical energy generation and supply, in particular for mobile communication systems, which, according to the invention, performs the rolling movement of rollers, e.g. for rolling cases used for energy generation by integrating bar magnets in the rollers and one or more coils on the frame, housing for converting the magnetic field change into an electrical voltage or electrical current. The energy at the end of the coil can be temporarily stored, processed or used directly to supply energy to communication systems.

2. State of the art

Such energy generation systems are known to be achieved with generators. The mechanical work is converted into electrical energy.

The most important part of a power generator is, besides the rotating armature, a static magnetic field.

The magnetic field is generated by field magnets, usually electromagnets that are attached to the inner circumference of the generator housing and are excited by direct current in electromagnets. The armature, an iron core that is provided with a series of electrically conductive wire windings, is rotated by mechanical force so that the wire windings cut through a magnetic field, which creates an electrical current.

The current is drawn from the rotating armature, the collector, with the help of brushes.

Furthermore, as in the published patent application DE 100 44 490 AI (here document A), there is an energy generation system in which rotating coils and induction coils are guided past static permanent magnet arrangements.

Likewise, the published patent application DE 199 25 765 AI (here font B) describes a brushless external rotor generator.

2.1 Disadvantage of the state of the art

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

In one case, the system requires brushes or pantographs. Due to the rotation, the pantograph wears out, materially through abrasion or through oxidation of the contact surface, which again changes into changed electrical parameters e.g. in the contact resistance, has a negative impact.

In the description described in document A and in any conventional dynamo-based solution, an induction coil rotates around an axis, or in document B a permanent magnet arrangement. For this purpose, the dynamo system needs an axis that is not fully integrated and therefore in the event of excessive stress, for example due to increased weights, such as an overloaded those trolleys, wear out. Among other things, this leads to breaks and knocked out bearings.

Furthermore, in the case of a mobile energy supply in particular, the current mobility, robustness and thus ease of service and repair is an increased technical requirement, which is reflected in increased costs.

Furthermore, rotating bodies with other mechanical and at the same time electrical functions are known to be weak points in technical systems. The rotating coil generator wears out quickly at weak points such as pantographs, due to excessive turning power and environmental conditions, e.g. when rolling quickly, running with a trolley case, when used in extreme cold, heat, dirt and mechanical forces.

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

3. Task, representation of the invention

The object of the present invention is to provide a device or system which enables energy supply for mobile systems, e.g. in business travel, which supports mobility, is robust and almost maintenance-free and wear-free in use.

This object is achieved by a system according to claim 1.

4. Solution of the problem, representation of the invention

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

5. Advantages of the invention

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

This is shown by the fact that there is no mechanical wear for the functionality of the energy generation, e.g. there are no mechanically wearing brushes or oxidizing current collectors because there is a fixed decrease in current and voltage on the coil.

Next is the electrically conductive coil, at the coil end of the current; Voltage is removed, protected from mechanical damage, environmental influences, since the now rigid, non-rotating coil body is integrated in the sheathing of the transport device, especially when it comes to electrically well-insulating materials such as plastic, rubber.

Furthermore, the shaft and armature can be subjected to higher loads because the coil body is not located on it as in conventional systems. This leads to maintenance-free use.

Furthermore, the integrity of the magnetic body and bar magnet in the running mass of the wheel are optimally protected. Even breaks in the bar magnet due to external influences on the bars, eg excessive loads, have no negative effects Effect on the energy generation system, in contrast to conventional energy generation systems.

In a further embodiment, a system for generating an electronic short circuit of the coil, an opposing magnetic field that arises as a result is used for the braking effect on the shaft.

This can be used for braking on slopes, e.g. for a transport device, suitcase that should not exceed a maximum speed on a downhill gradient.

This can be solved in particular by using the proportional voltage generated as a trigger when a roll speed is exceeded. When the peak voltage, trigger voltage, triggering occurs, a short circuit at the coil end of the coil body is generated via control electronics. In this way, a counter magnetic field of the coil is built up and a braking effect on the shaft occurs automatically.

Further advantages of the invention are that mechanical actuation of a device, e.g. which is used to control the cursor and, according to the invention, can also be used for energy supply. Is on the personal computer (PC) e.g. By means of a computer mouse, joystick, which controls the cursor on the screen, according to the invention the movement of the ball can simultaneously be used to supply energy to the computer mouse, especially if it is wireless, radio-operated.

6.2 Detailed description of the preferred embodiments

Fig.l is a system, device in which the system according to the invention is used. The system, generator, dynamo machine described here consists of a bar magnet 31, or several coils fastened to the shaft, which is provided with a series of wire loops, the winding (electromagnet). If the shaft with the bar magnet attached to it is rotated by a mechanical force, a magnetic field cuts the wire windings and an electrical current (induction) is generated. The current is drawn off at the end of the coil 40 which is connected to the outer line 41, 42. The bar magnet 31 is or can be integrated within a wheel 30.

Fig.2 shows a conventional system, device

A conventional system, generator, dynamo machine consists of a (bent) bar magnet 31 horseshoe magnet, a coil 40 on an armature, an iron core, which is provided with a series of wire loops, the winding 40. If the armature is rotated by a mechanical force, the wire windings cut a magnetic field and an electrical current (induction) is generated. To decrease the current, in addition to the armature on the common shaft 11, the collector (commutator), which rectifies the alternating current generated in the armature winding as a result of constant switching, is converted into a pulsating direct current. The current is drawn 41.42 with the help of the brushes 12, small pieces of coal that grind on the commutator and are connected to the outer line.

Since the conductor cuts field lines of varying strength during the rotary movement, a pulsating current / voltage arises. The induced voltage / current is proportional to the amount of field lines that are cut within a time interval.

31 or magnetic particles integrated. As in FIG. 3a, this can be one or more bar magnets, which lie along the direction of rotation. These magnets are made entirely from the base material

32 enclosed. The material property of the base material is that it has no magnetic shielding effect. This means that the magnetic field must penetrate the material, with a magnetically damping base material negatively influencing the energy generation.

An induced voltage, current at the coil 40 is generated in the module 100 by means of rotating magnets and then passed on via a rectifier module 110, via a full-wave rectification in Graetz or bridge circuit. Diodes 111 are required for this. The pulsating DC voltage that is passed through by the rectifiers is then smoothed in module 120. The charging capacitor 121 is charged when the voltage rises and supplies current to the consumer between the two maximum values of the voltage. Here, the component 122 is a filter capacitor, which blocks the direct current, so that it lies entirely on the consumer. Since both charges flow out of the capacitor 121, the voltage at the charging capacitor 121 drops. The current flowing to the consumer can be regarded as a direct current on which an alternating current is superimposed. The amplitude of the alternating current is dependent on the capacitance of the capacitor and the current drawn from the capacitor during the voltage break, that is to say dependent on the resistance 132 of the consumer.
