Description

The invention relates to low-power sources of current used to power low-power radio equipment and recharge the batteries of cellular equipment, power low-power light sources. The device can serve as an emergency current source in field conditions, in places of technological disasters, in army units, etc.

Known devices for this purpose, using the energy of the sun, mechanical stress when the device is oscillating, and other drive devices.

The prototype of the invention is patent RU 2234638 (application No. 2001124880), published on 08/20/2004. The prototype includes a housing, a non-magnetic channel with coils on its surface and a magnetic ball placed in the channel. When the device is swinging in a plane along the channel axis, the ball rolls and a current is induced in the coils, which is accumulated by the electronic circuit, and can be used if necessary.

The disadvantages of the prototype are

- bipolar ball, which causes the uncertainty of the magnetic flux when rolling the ball along the channel and, as a result of this, a decrease in the efficiency of the device;

- the straightness of the channel requires its horizontal location otherwise, even with a slight slope, the ball rolls back to the end of the tube.

The invention solves the technical problem of obtaining a uniform signal when moving a magnetic ball along the channel with coils, while reducing the requirements for the horizontal position of the channel itself.

The problem is solved in that the microgenerator includes a channel of non-magnetic material with coils of electric wire around it, end chippers and a magnetic ball inside the channel, and the magnetic ball includes several permanent magnets in the form of truncated pyramids or cones (for example, six), united by unlike the poles with a common magnetic core located in the center of the ball, and the non-magnetic channel has a bend with the ends up.

The invention is illustrated in figure 1-4, where figure 1 shows the design of the microgenerator, figure 2 - schematic device of a magnetic ball. Figure 3 and figure 4 show examples of embedding a microgenerator in an autonomous current source, where 1 is a housing, 2 is a microgenerator, 3 is an electronic unit, 4 is an output adapter, (figure 3) and in a cell phone (figure 4).

The microgenerator contains a channel in the form of a non-magnetic tube 1 bent upwards, muffled from both ends by elastic bumpers 2. Coils (coil) with an electric wire 3 are placed on the tube.

Inside the tube there is a ball 4 of a non-magnetic matrix with several magnets 5, which are made in the form of (for example, six) truncated cones or pyramids, the narrow ends of which are connected by a magnetic core 6. The ball is covered with a non-magnetic shell 7 on top.

The microgenerator operates as follows. When the device is rocked, the ball rolls along the channel, in which magnetic field lines from the total magnetic field of all the pyramids cross the coil of the coils and the current is induced in them, which is removed from the output terminals, which enters the accumulation and recharge circuit of the booster battery. The processing circuit of the relieved voltage is normal and is not the subject of this application.

Such a microgenerator can be integrated into any low-voltage device (a cell or satellite phone, a charging device that is not connected to the electric network, a low-power transmitter), which during operation is subject to natural fluctuations, such as walking, running, riding in vehicles, swimming, etc. d.

The presence of a polymagnetic ball and bending of the channel provides a greater sensitivity of the device to its vibrations, and, accordingly, a higher efficiency.

Thus, the expected technical result from the invention is confirmed.
