Definitions

  • the invention relates to a portable electronic device according to claim 1.
  • 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.
  • the aforementioned portable electronic devices should have an ever lower weight and smaller dimensions and should be as inexpensive to manufacture.
  • 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.
  • 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.
  • 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.
  • an energy converter that converts mechanical energy into electrical energy
  • the mechanical energy that is frequently generated 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.
  • the kinetic energy that is automatically available for example, when a cell phone is worn, can be used.
  • a piezo transducer with which pressure can be converted into electrical energy.
  • thermal energy in particular the energy contained in temperature gradients
  • 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.
  • 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.
  • Fig. 1 shows an embodiment of the invention.
  • a portable electronic device 1 is shown schematically.
  • a device 1 can be, for example, without claim to completeness, a cell phone, organizer, notebook, mp3 player or the like.
  • 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-
  • 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
  • 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.
  • 4 piezo elements can be used as energy converters.
  • the piezo element consists of a crystal in which an electrical voltage is generated by the external action of pressure on the crystal.
  • the button pressure into electrical energy by pressing a button on device 1 via a pressure sensor.
  • 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.
  • 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.
  • 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.
