DE102006017585A1 - Electric current generating device e.g. remote control transducer, has permanent magnet with movable magnet armature and attached to coil in which electrical voltage is induced through movement of magnet armature - Google Patents

Abstract

The device has a permanent magnet (1) with a movable magnet armature (3) and attached to a coil (5) in which an electrical voltage is induced through a movement of the magnet armature, where the coil is arranged at a magnetic yoke (2). The magnet armature is connected with a spring guide (41) and is directly or indirectly connected with an actuator (6). The actuator is connected with a mechanism that activates an operating unit by physical and/or chemical event.

Description

The The invention relates to a device for generating electrical Strom, in particular a remote control transmitter according to the preamble of claim 1.

Known Remote control transmitters have a battery or an accumulator on.

outgoing From this prior art, the invention is based on the object to provide a device of the type mentioned, regardless of a battery or an accumulator works.

These The object is achieved by a Device solved, which has a permanent magnet, wherein the permanent magnet has a movable magnet. The permanent magnet is a Assigned coil in which by the movement of the armature a electrical voltage is induced. The device according to the invention is mechanically constructed in a simple manner and generates electrical For example, voltages of the order of 10 to 15 volts. In remote control transmitters is thus used in the prior art Battery or the accumulator replaced, the voltage of the invention is exactly in the range of the battery or accumulator voltage, so that existing electronic circuits used for remote control transmitter can be.

Further advantageous embodiments The invention are characterized in the subclaims.

The Invention will now be described by way of example with reference to the drawing.

there shows

1 a first embodiment of the device according to the invention, and

2 a second embodiment of the device according to the invention.

The inventive device for generating electrical power is particularly remote control transmitter. The in the 1 and 2 The device shown has a permanent magnet 1 on, a moving magnet armature 3 having. The permanent magnet 1 is a coil 5 assigned in by the movement of the magnet armature 3 an electrical voltage is induced. In particular, the coil 3 on a magnetic yoke 2 arranged; it is connected to a wireless electronic circuit, not shown in the figures.

In the embodiment shown in the drawing, the movable armature is 3 with at least one spring tongue 41 . 42 , here with two spring tongues, connected.

The in 1 shown movable magnet armature 3 is directly or indirectly with an actuator 6 connected. This is, for example, a manual operation handle. By force in the direction of the downward arrow is the armature 3 shifted and at the same time tensions the spring tongues 41 . 42 , By the radius extending through the pivot point of the actuator 6 yields, the armature is released and oscillates or oscillates over the arrangement of magnetic yoke and magnet. In this case, an alternating magnetic field is established, which induces a voltage in the coil.

Instead of in 1 illustrated actuating element 6 is in the embodiment according to 2 a one-time locking provided in the tensioned state. The armature snaps into place 3 in a lock 7 , which when reaching a predetermined temperature, for example in the range of 60 to 150 ° Celsius a bimetallic release 8th activated. In general, the magnet armature can be connected to a mechanism which releases the tensioned armature triggered by at least one physical and / or at least one event. The physical event is the achievement of a temperature, an air pressure, a humidity, and / or an acceleration. However, the invention is not limited thereto. An example of a chemical event is a failure in a container in which acid is stored or processed.
