Description

Tragbares Elektronisches GerätPortable electronic device
Die Erfindung betrifft ein tragbares elektronisches Gerät gemäß Patentanspruch 1.The invention relates to a portable electronic device according to claim 1.
Allgemein bekannt sind tragbare elektronische Geräte wie Notebook, Organizer, Handy etc.. Diese werden für den üblichen Einsatz durch einen Energiespeicher mit elektrischer Energie versorgt. Je nach Energiebedarf ist für diese Geräte entweder eine Batterie, die im entladenen Zustand durch eine neue ersetzt und als Sondermüll entsorgt wird oder ein wiederaufladbarer Akkumulator vorgesehen. Kleine und leichte Akkumulatoren sind entweder teuer oder weisen nur eine geringe Speicherkapazität auf.Portable electronic devices such as notebooks, organizers, cell phones, etc. are generally known. These are supplied with electrical energy for normal use by an energy store. Depending on the energy requirement, either a battery is provided for these devices, which is replaced by a new one when discharged and disposed of as special waste, or a rechargeable battery is provided. Small and light accumulators are either expensive or have only a small storage capacity.
Nunmehr sollen die zuvor erwähnten tragbaren elektronischen Geräte ein immer geringeres Gewicht und geringere Abmessungen aufweisen und möglichst kostengünstig herstellbar sein.Now, the aforementioned portable electronic devices should have an ever lower weight and smaller dimensions and should be as inexpensive to manufacture.
Somit liegt der Erfindung die Aufgabe zugrunde, ein tragbares elektronisches Gerät vorzusehen, bei dem die Speicherkapazität des Energiespeichers für die elektrische Energie bei maximaler Betriebszeit möglichst gering ist oder der Energiespeicher möglichst selten ausgewechselt oder über eine Lade- Vorrichtung aus einem stationären Spannungsnetz aufgeladen werden muß.The invention is therefore based on the object of providing a portable electronic device in which the storage capacity of the energy store for the electrical energy is as small as possible at maximum operating time or the energy store has to be replaced as rarely as possible or has to be charged from a stationary voltage network via a charging device.
Diese Aufgabe wird erfindungsgemäß durch die im Patentanspruch 1 angegebenen Maßnahmen gelöst .This object is achieved by the measures specified in claim 1.
Dadurch, daß das tragbare elektronische Gerät einen Energiewandler zum Wandeln nicht elektrischer, nicht strahlender Energie in elektrische Energie aufweist, ist es möglich, beim üblichen Gebrauch des tragbaren elektronischen Geräts die Entnahme der gespeichert Energie aus dem Energiewandler zu minimieren oder entnommene Energie zu ersetzen ohne das trag- bare elektronische Gerät am stationären Netz aufzuladen oder den Energiespeicher auszutauschen.The fact that the portable electronic device has an energy converter for converting non-electrical, non-radiating energy into electrical energy, it is possible to minimize the removal of the stored energy from the energy converter or to replace extracted energy during normal use of the portable electronic device without the supporting Charge bare electronic device on the stationary network or replace the energy storage.
Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.Further advantageous embodiments of the invention are specified in the subclaims.
Dadurch, daß die aus nicht-elektrischer, nicht-strahlender Energie durch Wandlung gewonnene elektrische Energie dem auf- ladbaren Energiespeicher 2 und/oder dem elektronischen Ver- braucher zuführbar ist, ist diese mit maximalem Wirkungsgrad einsetzbar. Das bedeutet, die gewonnene Energie wird dorthin geleitet, wo sie mit dem besten Wirkungsgrad einsetzbar ist.Because the electrical energy obtained from non-electrical, non-radiating energy by conversion can be supplied to the rechargeable energy store 2 and / or the electronic consumer, it can be used with maximum efficiency. This means that the energy obtained is directed to where it can be used with the best efficiency.
Durch den Einsatz eines Energiewandlers, der mechanische Energie in elektrische Energie wandelt, kann die insbesondere beim Betrieb tragbarer Geräte häufig anfallende mechanische Energie zum Wandeln in elektrische Energie genutzt werden. Dabei können wahlweise oder akkumulativ die Energie, die in einer Bewegung, einer Beschleunigung oder beim Anwenden von Druck anfällt, in elektrische Energie gewandelt werden. Auf diese Weise wird die durch die beim Tragen eines Handys beispielsweise automatisch zur Verfügung stehende Bewegungsenergie nutzbar gemacht. Insbesondere sei auf einen Piezowandler hingewiesen, mit dem Druck in elektrische Energie wandelbar ist.By using an energy converter that converts mechanical energy into electrical energy, the mechanical energy that is frequently generated, particularly when operating portable devices, can be used for converting it into electrical energy. The energy that arises in a movement, an acceleration or when pressure is applied can be converted into electrical energy either selectively or accumulatively. In this way, the kinetic energy that is automatically available, for example, when a cell phone is worn, can be used. In particular, reference is made to a piezo transducer with which pressure can be converted into electrical energy.
Weiterhin ist es möglich mittels des Energiewandlers Wärmeenergie, insbesondere die Energie, die in Temperaturgradienten steckt, in elektrische Energie zu wandeln. De Vorteil liegt darin, daß die Speicherfähigkeit von Batterien und Akkumulatoren bei tiefen Temperaturen sinkt, der Temperaturgradient zur Körpertemperatur einer Hand beispielsweise aber steigt. Somit kann durch die Körperwärme, wenn das tragbare elektronische Gerät, ein Handy beispielsweise, in der Hand gehalten wird, bei sinkender Temperatur zunehmend elektrische Energie, beispielsweise mittels eines Peltierelementes, gewonnen werden. Auf diese Weise ist zumindest die verminderte Speicher- fähigkeit des Energiespeichers bei tiefen Temperaturen ausgleichbar.It is also possible to convert thermal energy, in particular the energy contained in temperature gradients, into electrical energy by means of the energy converter. The advantage is that the storage capacity of batteries and accumulators decreases at low temperatures, but the temperature gradient to the body temperature of a hand, for example, increases. As a result, the body heat, when the portable electronic device, for example a cell phone, is held in the hand, can increasingly generate electrical energy, for example by means of a Peltier element, when the temperature drops. In this way, at least the reduced storage The capacity of the energy storage device can be compensated for at low temperatures.
Nachfolgend wird die Erfindung unter Bezugnahme auf die Zeichnung an Hand von Ausführungsbeispielen im einzelnen erläutert .The invention is explained in detail below with reference to the drawing using exemplary embodiments.
Es zeigt :It shows :
Fig. 1 ein erfindungsgemäßes Ausführungsbeispiel.Fig. 1 shows an embodiment of the invention.
In dem in Fig. 1 dargestellten erfindungsgemäßen Ausführungs- beispiel ist schematisch ein tragbares elektronisches Gerät 1 dargestellt. Ein solches Gerät 1 kann beispielsweise, ohne Anspruch auf Vollständigkeit, ein Handy, Organizer, Notebook, mp3 -Player oder ähnliches sein. Wie in Fig. 1 dargestellt ist, weist dieses Gerät zumindest einen elektronischen Verbraucher 5 auf, durch den die Funktionalität des tragbaren elektronischen Gerätes 1 bestimmt ist. Als Energiequelle ist ein aufladbarer Akkumulator 2 vorgesehen. Dabei ist es für die Erfindung unwesentlich, ob es sich um einen NiCa-In the exemplary embodiment according to the invention shown in FIG. 1, a portable electronic device 1 is shown schematically. Such a device 1 can be, for example, without claim to completeness, a cell phone, organizer, notebook, mp3 player or the like. As shown in FIG. 1, this device has at least one electronic consumer 5, by which the functionality of the portable electronic device 1 is determined. A rechargeable battery 2 is provided as the energy source. It is irrelevant to the invention whether it is a NiCa-
Akkumulator, einen Li- Ionen-Akkumulator oder eine andere Akkumulatortypen handelt. Auch ist der Einsatz einer nur einmalig verwendbaren Batterie bei Beibehaltung des allgemeinen Erfindungsgedanken möglich.Accumulator, a Li-ion accumulator or another type of accumulator. The use of a battery that can only be used once is also possible while maintaining the general inventive concept.
Zusätzlich zu dem vorangestellten Einrichtungen weist das Gerät 1 einen Aufnehmer 6 auf. Dieser Aufnehmer 6 nimmt nicht elektrische, nicht strahlende Energie auf. Darunter ist zu verstehen, mechanische Energie, wie sie beispielsweise aus einer Bewegung, Beschleunigung oder dem Vorliegen einesIn addition to the above devices, the device 1 has a sensor 6. This sensor 6 absorbs non-electrical, non-radiating energy. This is understood to mean mechanical energy, such as that resulting from movement, acceleration or the presence of a
Drucks, und weiterhin auch thermische Energie, beispielsweise aus dem Vorliegen von Temperaturunterschieden gewinnbar ist. Die so vom Gerät 1 mittels des Aufnehmers 6 aufgenommenen Energie wird dem Energiewandler 4 zugeführt . Im Energiewand- 1er 4 wird einer der zuvor nicht abschließend aufgeführtenPressure, and also thermal energy, for example, can be obtained from the presence of temperature differences. The energy thus absorbed by the device 1 by means of the transducer 6 is fed to the energy converter 4. In the energy wall 1er 4 one of the previously not listed is
Energien in eine elektrische Energie, d.h. Strom und Spannung gewandelt . Zum besseren Verständnis sei hier dargelegt, was gemeint sein kann. Hier ist an einen Dynamo gedacht, der mit den mechanische Drehwalzen einer sog. "Maus" verbunden ist, die zur Auf- nähme einer Relativbewegung der Maus auf einer fiktiven der Bildschirmläche eines Computers entsprechenden Fläche dienen. Gemeint sind aber auch "Schüttelwerke", wie sie aus mechanischen Automatikarmbanduhren bekannt sind. Damit wird durch eine schüttelnde Bewegung eines Handys beispielsweise eine Drehbewegung an einem Dynamo erzeugt. Weiterhin ist auch eine Anordnung umfaßt, bei der Magnete durch die Schüttelbewegung, d.h. mehrfaches Beschleunigen in unterschiedliche Richtungen, ein bewegtes Magnetfeld in einer festen Spulenanordnung erzeugen, wodurch in dieser eine Spannung induziert wird. Wei- terhin sind als Energiewandler 4 Piezoelemente einsetzbar.Energies converted into electrical energy, ie current and voltage. For a better understanding, it is explained here what can be meant. Here we are thinking of a dynamo that is connected to the mechanical rotating rollers of a so-called “mouse”, which serve to record a relative movement of the mouse on a fictitious surface corresponding to the screen area of a computer. But it also means "shaking mechanisms" as they are known from mechanical automatic wristwatches. With a shaking movement of a cell phone, for example, a rotary movement is generated on a dynamo. Furthermore, an arrangement is also included in which magnets generate a moving magnetic field in a fixed coil arrangement by means of the shaking movement, ie, multiple acceleration in different directions, as a result of which a voltage is induced therein. Furthermore, 4 piezo elements can be used as energy converters.
Das Piezoelement besteht aus einem Kristall, in dem durch die äußere Einwirkung von Druck auf den Kristall eine elektrische Spannung erzeugt wird.The piezo element consists of a crystal in which an electrical voltage is generated by the external action of pressure on the crystal.
Neben der Energie, die in der beschleunigten Masse des Gerätes oder des bewegten Gerätes steckt. Ist es auch möglich über einen Druckaufnehmer beim Drücken einer Taste des Gerätes 1, den Tastendruck in elektrische Energie umzusetzen. Schließlich sei noch darauf hingewiesen, daß auch Temperatu- runterschiede beispielsweise über sog. Peltierelemente in elektrische Energie wandelbar ist. Ist das Gerät 1 beispielsweise ein Handy, so wird dieses für den Gebrauch in die Hand genommen. Dabei erlangt ein Teil der Oberfläche Kontakt mit der Handfläche, die Körpertemperatur aufweist. Der restliche Teil der Geräteoberfläche steht mit der Umwelt thermisch in Verbindung, die in den seltensten Fällen Körpertemperatur aufweist. Sobald eine Temperaturdifferenz vorliegt, ist aus dieser eine Enegiegewinnung möglich.In addition to the energy contained in the accelerated mass of the device or the moving device. Is it also possible to convert the button pressure into electrical energy by pressing a button on device 1 via a pressure sensor. Finally, it should also be pointed out that temperature differences can also be converted into electrical energy, for example via so-called Peltier elements. If the device 1 is, for example, a cell phone, it is picked up for use. Part of the surface comes into contact with the palm of your hand, which is at body temperature. The rest of the device surface is thermally connected to the environment, which rarely has body temperature. As soon as there is a temperature difference, energy can be obtained from it.
Die so gewonnene elektrische Energie wird einer Schaltung 3 zugeführt . In der Schaltung 3 erfolgt eine Pegelanpassung an benötigt Versorgungsspannungspegel für den elektronischen Verbraucher 5. Zusätzlich oder alternativ sorgt die Schaltung dafür, daß der Akkumulator 2, in geeigneter Weise aufgeladen wird. Dies ist für den Fall ausgenommen, wenn anstelle eines Akkumulator oder Kondensator - der auch denkbar ist - eine nicht aufladbare Batterie eingesetzt ist. In diesem Fall sorgt die Schaltung 3 dafür, daß die gewonnene Energie dem Verbraucher 5 zugeführt wird und im gleichen Maße die Entnahme von Energie aus der Batterie reduziert wird.The electrical energy thus obtained is fed to a circuit 3. In circuit 3 there is a level adjustment to the required supply voltage level for the electronic one Consumer 5. Additionally or alternatively, the circuit ensures that the accumulator 2 is charged in a suitable manner. This is not the case if a non-rechargeable battery is used instead of an accumulator or capacitor - which is also conceivable. In this case, the circuit 3 ensures that the energy obtained is supplied to the consumer 5 and the removal of energy from the battery is reduced to the same extent.
Bei der Verwendung kann es günstiger sein die gewonnene Energie grundsätzlich dem Akkumulator oder Kondensator zuzuführen. Die Energie für das Betreiben des elektronischen Verbrauchers 5 erfolgt dann aus dem Akkumulator oder Kondensators .When using it, it may be cheaper to generally supply the energy gained to the accumulator or capacitor. The energy for operating the electronic consumer 5 then comes from the accumulator or capacitor.
Als weitere Ausgestaltung der Erfindung sei noch angegeben, daß der Aufnehmer 6 mit einem Zwischenspeicher verbunden sein kann. In diesem wird die mechanische Energie zwischengespeichert. Dies hat den Vorteil, daß die Wandlung von echani- scher Energie in elektrische Energie kontinuierlich erfolgen kann. So ist es möglich mittels eines Schüttelaufnehmers entsprechend der beschleunigten Bewegung eine Feder zu spannen, die wiederum beispielsweise kontinuierlich einen Dynamo antreibt . As a further embodiment of the invention, it should also be stated that the transducer 6 can be connected to an intermediate store. The mechanical energy is temporarily stored in this. This has the advantage that the conversion of mechanical energy into electrical energy can take place continuously. It is thus possible to tension a spring by means of a shake pick-up according to the accelerated movement, which in turn continuously drives a dynamo, for example.
