Description

The invention relates to the field of electrical engineering and can be used to charge the batteries of any mobile communications device, including cell phone, smartphone, cordless phone, tablet, etc. by converting mechanical energy into electrical energy.

A mobile phone is a portable means of communication intended primarily for voice communication. Currently, cellular communication is the most widespread of all types of mobile communication, which is why a mobile phone is often called a mobile phone, although mobile phones, in addition to cell phones, are also satellite phones, radiotelephones and trunk communication devices. Any of the above devices has a limited battery life and time. A mobile phone is a must-have thing these days. And with it - and his battery. And, of course, most of us recall its existence no more than twice a week - when a mobile phone refuses to work. Manufacturers of cell phones and batteries for them solve this problem in different ways. Some, such as Philips, create batteries with extended battery life, others go the way of reducing the ergonomics of devices, while others leave everything as it is, forcing the owner to charge the battery once every two days. We offer a charger built into the body of certain types of devices and capable of supporting battery power.

This invention relates to primary sources of electricity. The device consists of two elastic chambers, separated by a partition, in which a channel is located, inside of which there is an electric generator made synchronous with excitation from a permanent magnet, with an impeller having the form of a propeller with several, at least three, curved blades, as well as supports, rectifier and battery unit and universal plug for connecting a consumer.

The disadvantages of this device for generating electricity is the use of air masses and operations that are not directly related to the use of a cell phone for its intended purpose.

This cell phone contains the main and backup batteries in one phone case with separate display indicators “charge-discharge battery”, one of which is for the main and the second for the backup battery and a push-button micro switch installed in the phone’s body, which provides a push-button transfer of phone power from one battery to the other and vice versa.

Disadvantages: high weight and low reliability, due to the fact that the backup battery can also "sit down" in 2 ... 3 days even when not in use.

A mobile communication device (Fig. 1 ... 15) contains a housing 1, a keyboard 2, a display 3, a microphone 4, and a speaker 5. Inside the housing 1, an electronic board 6 is installed, connected by electrical connections 7 to a microphone 4 and a speaker 5, and a battery 8 connected by electric wires 9 with an electronic board 6, an electric generator 10, which wires 11 containing a circuit breaker 12 are connected to the battery 8 (Fig. 1).

In this case, the electric energy generator 10 comprises a housing 13, in the cells 14 of which permanent magnets 15 are installed. Excitation windings 16 are made concentrically to the longitudinal axes of all cells 14.

Permanent magnets may have a coating 17 of anti-friction material. Also, on the inner surfaces of the cells 14, a coating 18 of antifriction material can be made. At the ends of the cells 16, perpendicular to their longitudinal axes 00, shock absorbers 19 can be installed.

Cells 14 can be made in the form of a parallelepiped with a base in the shape of a circle (Fig. 2) or in the form of a hexagon (Fig. 3). Between the electric generator 10 and the battery 8, a converter 20 is installed, designed to reduce voltage and stabilize it. It is possible to install at the outlet of the generator 10 in front of the circuit breaker 12 of the energy storage device 21 in the form of a capacitor (Fig. 1) to prevent overcharging of the battery 8.

There are two possible layouts of the electric generator 10, which is made in the housing 13 from a dielectric material (Fig. 5).

In the first embodiment, the housing 13 is mounted on the housing 1 of the mobile communication means (the fastening means in Fig. 1 ... 15 are not shown), and the connector 22 of the mobile communication means and the connector 23 of the generator 10 are connected by a cable 24 (Fig. 6). In this case, the proposed invention can be used on previously manufactured mobile communications.

In the second embodiment, the housing 13 of the electric generator 10 is installed inside the housing 1 of the mobile communication means (Fig. 7). This option is preferable.

In FIG. 8 shows a variant of an electric generator 10 with two groups of cells 14 having a square (rectangular) base and cylindrical loads 15, while the longitudinal axis of the cells 14 of the two groups are mutually perpendicular. This is done to use vibration in any direction. In FIG. 9 shows a variant of an electric generator 10 installed outside the housing 1 of a mobile communication device and with loads 15 of a cylindrical shape; FIG. 10 shows a variant of an electric generator 10 installed inside the housing 1 of a mobile communication device and cylindrical loads 15. In FIG. 11 and 12 show an electric generator 10 with loads 15 in the shape of a ball. In FIG. 13 shows a hexagonal cell 14.

In FIG. 14 and 15, an electric generator 10 is provided with permanent magnets 15 mounted without a gap in order to exclude lateral impacts on the side walls of cells 1 and their quick destruction.

Installing permanent magnets in round cells without a gap will prevent them from moving due to air compression under them, and installing with a gap will lead to impacts on the side walls of the cells.

When working with a mobile means of communication, for example a cell phone, the subscriber is at least 30% of the time per day in motion, moves on foot, rides in a car and moves around the office. In this case, the permanent magnets 15 oscillate and excite an electric current in the field windings 16, constantly generating electrical voltage in them. The current through the wires 11 is supplied to the Converter

20 to reduce and stabilize the voltage and further into the battery 8 and constantly charges it. When the battery 8 is fully charged, the circuit breaker 12 disconnects the electric power generator 10 from the battery 8. The circuit breaker 12 can be controlled by the voltage output from the battery 8 (voltage measuring device in Fig. 1 is not shown).

The use of a coating 17 and 18 of antifriction material contributes to the sliding of the permanent magnets 15 in the cells 14 and increases the efficiency of the electric generator 10. The use of shock absorbers 19 (Fig. 3) also contributes to the rebound of the permanent magnets when they hit the end walls of the cells 14. Performing two groups of cells 14 with each other perpendicular axes (Fig. 8 ... 10) increases the efficiency of the generator 10, because in practice (when wearing a mobile communication device), vibrations in all planes act on it.

The use of the invention has significantly improved the reliability and service life of a mobile communication device by eliminating side impacts on the side walls of the cells and preventing their rapid destruction.
