Indem erfindungsgemäß ein Akku in einem Mobilfunkendgerät unter Umwandlung der Bewegungsenergie (relativ zwischen dem Akku und dem Mobilfunkendgerät) des Akkus in elektrische Energie aufgeladen wird, ist der Akku völlig unabhängig von öf- fentlichen elektrischen Stromversorgungsnetzen und kann allein durch hinreichende Bewegung eines in einem Mobilfunkendgerät befindlichen Akkus aufgeladen werden.In that, according to the invention, a rechargeable battery in a mobile radio terminal is converted into electrical energy by converting the kinetic energy (relative between the battery and the mobile radio terminal) of the battery, the battery is completely independent of public electrical power supply networks and can be operated only by sufficient movement of one in a mobile radio terminal Batteries can be charged.
Nach einer Ausgestaltung der Erfindung ist der Akku im Mobilfunkendgerät mit mindestens einem rotativen Freiheitsgrad ge- lagert, insbesondere exzentrisch (mit einem relativ zu einer Drehachse des Akkus versetzten Schwerpunkt 4 des Akkus) , so dass durch Bewegung des Handys ausgelöste rotative Bewegung des exzentrisch gelagerten Akkus bzw. damit verbundene rotative Energie des Akkus durch eine Bewegungsenergieumwand According to one embodiment of the invention, the rechargeable battery is stored in the mobile radio terminal with at least one rotational degree of freedom, in particular eccentrically (with a center of gravity 4 of the rechargeable battery that is offset relative to an axis of rotation of the rechargeable battery), so that rotational movement of the eccentrically mounted rechargeable battery triggered by movement of the mobile phone or the associated rotational energy of the battery through a kinetic energy conversion
lungseinrichtung in elektrische Energie zur Ladung des Akkus umgewandelt werden kann. Dabei wird vorzugsweise eine am Akku und am Mobilfunkendgerät festgelegte Spuleneinrichtung (mit einer Spule sowie einer zweiten Spule oder einem Permanent- magneten) verwendet, um Bewegungsenergie des Akkus aufgrund einer Relativbewegung eines Magnetfeldes B zu einer Spule 8 in elektrische Energie umzuwandeln.tion device can be converted into electrical energy for charging the battery. In this case, a coil device (with a coil and a second coil or a permanent magnet) fixed on the battery and on the mobile radio terminal is preferably used to convert kinetic energy of the battery due to a relative movement of a magnetic field B to a coil 8 into electrical energy.
Nach einer alternativen Ausgestaltung der Erfindung ist der Akku translatorisch in mindestens eine Richtung auf einem Schlitten relativ zum Mobilfunkendgerät verschiebbar angeordnet, wobei ebenfalls eine oder mehrere Spuleneinrichtungen zur Umwandlung von Bewegungsenergie des Akkus in elektrische Energie zur Ladung des Akkus vorgesehen sein können.According to an alternative embodiment of the invention, the rechargeable battery is arranged to be translatable in at least one direction on a carriage relative to the mobile radio terminal, wherein one or more coil devices can likewise be provided for converting kinetic energy of the rechargeable battery into electrical energy for charging the rechargeable battery.
Eine elektrische Verbindung zwischen dem Akku und dem Mobil- funkendgerät zur Stromversorgung des Mobilfunkendgerätes durch den Akku und/oder Aufladung des Akkus kann durch eine Ladevorrichtung umfassend am Akku einerseits und am Mobilfunkendgerät andererseits festgelegte Schleifkontakte realisiert sein; in einem einfachen Fall kann die Ladevorrichtung auch der Anschluss des Akkus an die Bewegungsenergieumwandlungeinrichtung sein.An electrical connection between the battery and the mobile radio terminal for the power supply of the mobile radio terminal by the battery and / or charging the battery can be realized by a charging device comprising sliding contacts fixed on the battery on the one hand and on the mobile terminal on the other hand; in a simple case, the charging device can also be the connection of the rechargeable battery to the kinetic energy conversion device.
Ein Vorteil einer Spuleneinrichtung zur Umwandlung von Bewegungsenergie des Akkus in elektrische Energie zum Laden des Akkus ist, dass eine derartige Spulenanordnung gleichzeitig als Vibrations-Alarmvorrichtung des Mobilfunkendgerätes verwendet werden kann, die insbesondere für einen Vibrationsalarm den Akku durch (dem Akku entnommene) elektrische Energie über die Spulenanordnung relativ zum Mobilfunkendgerät in Bewegung setzen kann. Zweckmäßig ist zur Ladung eines Gleichspannungsakkus eineAn advantage of a coil device for converting kinetic energy of the battery into electrical energy for charging the battery is that such a coil arrangement can be used at the same time as a vibration alarm device of the mobile radio terminal, which, in particular for a vibration alarm, transfers the battery through (electrical energy removed from the battery) can set the coil arrangement in motion relative to the mobile radio terminal.

Dabei zeigtFurther features and advantages of the invention result from the patent claims and the following description of an embodiment with reference to the drawing. It shows
Figur 1 schematisch eine erfindungsgemäße Anordnung zum Aufladen eines Akkus .Figure 1 shows schematically an inventive arrangement for charging a battery.
Figur 1 zeigt schematisch im Querschnitt für das Verständnis der Erfindung relevante Komponenten eines Mobilfunkendgerätes 1. Aufbau und Funktion von Mobilfunkendgeräten sind dem Fachmann an sich (z.B. aus www.ETSI.org betreffend den GSM Stan- dard oder aus anderen Standards) bekannt, so dass hier nur für die Erfindung relevante Komponenten beschrieben werden müssen.FIG. 1 shows schematically in cross section components of a mobile radio terminal 1 which are relevant for understanding the invention. The structure and function of mobile radio terminals are known per se to a person skilled in the art (for example from www.ETSI.org with regard to the GSM standard or from other standards), so that only components relevant to the invention need to be described here.
Der Akku 2 des Mobilfunkendgerätes ist im in Figur 1 vorliegenden Beispiel um eine Drehachse 3 relativ zum Mobilfunkend- gerät 1 drehbar gelagert. Dabei ist der Schwerpunkt des Akkumulators 2 senkrecht zur Drehachse 3 versetzt (beispielsweise durch eine zur Mitte des Akkus versetzte Anordnung auf der Drehachse oder durch Anbringen eines Gewichtes am Akku) .In the example shown in FIG. 1, the rechargeable battery 2 of the mobile radio terminal is mounted so as to be rotatable about an axis of rotation 3 relative to the mobile radio terminal 1. The center of gravity of the accumulator 2 is offset perpendicular to the axis of rotation 3 (for example by an arrangement on the axis of rotation offset to the center of the battery or by attaching a weight to the battery).
Eine elektrische Verbindung zwischen dem Akku 2 und dem Mo- bilfunkendgerät 1 kann beispielsweise durch einen Schleifkontakt 5 am Mobilfunkendgerät 1 (beispielsweise ein zentrisch zur Rotationsachse 3 des Akkus angeordneter Schleifring 5) und einen den Schleifring 5 berührenden Schleifkontakt 6 am Akku 2 für jeden der Pole des Akkus 2 vorgesehen sein, so dass über die Schleifkontakte das Mobilfunkendgerät mit Strom vom Akku versorgt werden kann und der Akku durch eine (zweckmäßig im Mobilfunkendgerät angeordnete oder am Akkus festgelegte) Ladeeinrichtung aufgeladen werden kann.An electrical connection between the rechargeable battery 2 and the mobile radio terminal 1 can be established, for example, by a sliding contact 5 on the mobile radio terminal 1 (for example a slip ring 5 arranged centrally to the axis of rotation 3 of the rechargeable battery) and a sliding contact 6 on the rechargeable battery 2 touching the slip ring 5 for each of the poles of the battery 2 can be provided so that the mobile terminal can be supplied with power from the battery via the sliding contacts and the battery can be charged by a charging device (expediently arranged in the mobile terminal or fixed to the battery).
Die Umwandlung von rotativer Bewegungsenergie des Akkus in e- lektrische Energie kann z.B. durch einen an sich dem Fachmann bekannten Stromgenerator erfolgen. Hierfür kann eine Spuleneinrichtung vorgesehen sein. Die Spuleneinrichtung kann z.B. eine Spule 9 (z.B. seitens des Mobilfunkendgerätes) und eine weitere Spule 8 (z.B. seitens des Akkus) oder einen oder meh The conversion of rotational kinetic energy of the accumulator into electrical energy can take place, for example, by a current generator known per se to the person skilled in the art. A coil device can be provided for this. The coil device can, for example, have a coil 9 (for example on the part of the mobile radio terminal) and a further coil 8 (for example on the part of the battery) or one or more
rere Permanentmagnete umfassen, so dass zwei Spulen oder eine Spule und ein Permanentmagnet relativ zu einander bewegt werden, so dass aufgrund einer Magnetfeldbewegung elektrische Spannung in einer Spule erzeugt wird, welche über eine an sich bekannte Gleichrichteranordnung (beispielsweise mit zwei Dioden und ggf. einem Kondensator) erforderlichenfalls gleichgerichtet werden kann und zur Aufladung des Akkumulators 2 (ggf. über Schleifkontakte etc.) verwendet werden kann. Da ein Akku eine relativ hohe Masse haben kann, kann aus seiner Bewegung relativ viel Energie gewonnen werden, um ihn aufzuladen. Ein erfindungsgemäßes Mobilfunkendgerät ist autark und unabhängig von einer Stromversorgung durch öffentliche Stromversorgungsnetze. Anstatt der dargestellten Umwandlung rotativer Energie, die der Akku relativ zum Mobilfunkendgerät beim Bewegen des Mobilfunkendgerätes aufgrund einer Unwucht des Akkumulators gewinnt, kann auch Bewegungsenergie einer Längsbewegung (=translatorischen Bewegung) des Akkus in elektrische Span- nung (elektrische Energie) umgewandelt werden, um den Akku 2 aufzuladen. rere permanent magnets include, so that two coils or a coil and a permanent magnet are moved relative to each other, so that due to a magnetic field movement electrical voltage is generated in a coil, which via a known rectifier arrangement (for example with two diodes and possibly a capacitor ) can be rectified if necessary and can be used to charge the accumulator 2 (if necessary via sliding contacts etc.). Since a battery can have a relatively high mass, a lot of energy can be gained from its movement in order to charge it. A mobile radio terminal according to the invention is self-sufficient and independent of a power supply through public power supply networks. Instead of the conversion of rotational energy shown, which the battery gains relative to the mobile terminal when the mobile terminal is moved due to an imbalance of the battery, kinetic energy of a longitudinal movement (= translational movement) of the battery can also be converted into electrical voltage (electrical energy) by the Charge battery 2.
