Description

The invention relates to chargers for batteries of mobile devices, made with the possibility of use in extreme situations - in the absence of an alternating electric current network.

The prior art charger for the batteries of mobile phones (see Korean patent No.20120017014, publ. 08/27/2012), which includes an electric generator containing a micro-electromechanical system with a moving core and a winding, and a supercapacitor. The principle of operation is based on the fact that when a person moves, a movably-fixed core makes movements, and the EMF is induced in the winding.

A disadvantage of the known device is its low versatility and performance.

In addition, from the "prior art" known battery charger described in the patent of the Russian Federation No. 27754 for utility model, publ. 02/10/2003, which contains a housing with a connector for connecting a battery, an internal circuit device including an AC rectification circuit supplied from a power source and a voltage stabilization circuit for the received direct current, an electric generator located inside the housing and including a stator, a movable rotor, and drive for transmitting external mechanical motion to the rotor. In this case, external mechanical movement is carried out due to the muscular strength of the hand.

A disadvantage of the known device is that it can only be used by people with developed muscles of the hands.

The objective of this utility model is to eliminate the above disadvantages.

The technical result is to increase the versatility and increase the productivity of this device.

The technical result is ensured by the fact that the charger for batteries of mobile devices contains a housing with a connector that provides connection to the battery of mobile devices, an internal circuit device including a supercapacitor connected to an electric energy source in the form of an electric generator containing a magnetic circuit, a winding, a permanent magnet and a movable a core made with the ability to move due to inertial forces arising from the movement of the housing of the charger, and by muscular force.

In accordance with particular cases, the device may have the following features.

The movable core is made with a displaced center of gravity.

The movable core is made in the form of a body of revolution with a sinker located inside it, in the lower part.

The surface of the magnetic core from the side of the air gap is developed by the teeth, in addition, at least a part of the outer surface of the movable core facing the developed surface of the magnetic core also has teeth.

The charger is configured to attach a removable handle to the core, providing movement of the core using muscular strength.

The circuit device further comprises a voltage converter.

The technical essence of this utility model is illustrated by an illustration in which the device is shown in a schematic view.

The charger contains the following structural elements.

1 - magnetic circuit;

2 - core;

3 - winding;

4 - permanent magnet;

5 - rectifying unit;

6 - supercapacitor;

7 - voltage converter;

8 is a mobile tool.

The inventive charger converts the mechanical energy of a moving person or his muscular strength into an output current of constant polarity for charging a supercapacitor 6. The electric generator contains a magnetic circuit 1, a soft magnetic core 2 with a displaced center of gravity, made in the form of a hollow body of revolution (for example: a cylinder) with a sinker, located in its lower part, the winding 3 and the permanent magnet 4. The magnetic core 1 and the movable core 2 may have teeth from the side of the air gap. While the air gap is formed between the outer surface of the movable core 2 and facing the surface of the magnetic circuit 1. Accordingly, the teeth are made on these surfaces. The voltage converter 7 provides a regular charge of the battery of the mobile device 8 with varying degrees of charge of the supercapacitor 6. This voltage converter 7 converts the voltage of the same polarity, but of a different level (depending on the charge level of the supercapacitor 6 into a constant voltage required to power the corresponding mobile device 8 The rectifier unit 5, which can be made in the form of a diode bridge, provides the conversion of pulse voltage AC second polarity when the magnetic flux (increase or decrease it, with a constant direction causes a change in flux in the coil 3 and therefore hover alternating polarity EMF).

The device operates as follows.

When you connect the mobile tool 8 through the connector to the housing of the power charger, the battery is charged from the supercapacitor 6 through the voltage converter 7. When the discharge of the supercapacitor 6 (threshold of the order of 1.5-1.6 V), the charging of the mobile tool 8 is stopped.

The electric generator provides charging of the supercapacitor 6. In this case, the core 2 of the electric generator changes its position as a result of the movement of a person. The core 2 is a hollow body with a sinker located in its lower part. The core 2 moves as a result of the action of inertia forces, but returns to its original position due to the peculiarities of its structural implementation and the action of the magnetic field.

Also, the movable core 2 changes its position under the action of muscular strength when using a removable handle attached to the core 2. Attachment of the removable handle is ensured by the fact that the housing is provided with an opening, and the movable core 2 is fixed.

When moving the movable core 2 in both cases, an EMF is induced in the winding 3, which is rigidly connected to the magnetic circuit 1 and the permanent magnet 4.

To increase the efficiency of the electric generator by increasing the rate of change of the magnetic flux, the magnetic core 1 and the movable core 2 have teeth on the surface from the side of the air gap.

The magnetic circuit 1 provides the passage of a magnetic flux excited by a permanent magnet 4 and an electric current flowing in the winding 3. To reduce losses in steel, the magnetic circuit 1 and the movable core 2 are made of separate plates “stacked” made up of a package.

The permanent magnet 4 will fulfill the role of a spring supporting the balance between the forces of magnetic attraction and gravitational, returns the movable core 2 to its original position after the termination of the inertial forces. The permanent magnet 4 creates a constant component of the magnetic flux, changes in this magnetic flux occur when the position of the core 2 changes, due to a change in the equivalent air gap. A variable air gap is a variable magnetic resistance of a magnetic circuit and, therefore, (according to Ohm's law for a magnetic circuit) a variable flux.

An alternating magnetic flux (having a constant component) induces a variable EMF in the winding, which is connected to the supercapacitor 6 through a rectifier unit. 5
