Description

The group of inventions 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 satellite phones, radio telephones and long-distance telephones are also mobile phones. 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.

Known charger according to the patent RU 2384930 IPC H02J 7/32, publ. March 20, 2010

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.

Known cell phone according to the patent of the Russian Federation for utility model No. 71842, IPC Н04М 1/00 publ. March 20, 2008

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.

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

Known cell phone according to the patent of the Russian Federation for the invention No. 2492568, IPC H02J 7/32, publ. 09/10/2013, the prototype of the method and device

The required technical result of this invention is achieved by the fact that in the proposed device the mechanical work of bringing the apparatus into working condition is accompanied by the operation of an electric generator built into the device and connected to the battery. The latter is recharged.

Such a charger, consisting of a telephone housing and an electric generator, a “slider” type housing having two parts, on one there is a pinion gear on the electric generator shaft, and on the other there is a gear rack located in parallel planes and connected using a special mechanism that allows them move (“slide”) relative to each other in these planes.

A possible version of the conversion of mechanical energy for a mobile phone type "slider", which contains: pinion and gear rack.

The charger for a mobile phone works as follows: when the cover is slid in devices of the “slider” type, mechanical work is transmitted via a rack-and-pinion transmission to an electric generator that generates electricity that is used to recharge the battery.

The rack-and-pinion gear is used to convert translational motion into rotational.

The proposed device has the following disadvantages.

- the mechanical generator produces very little energy is not enough to recharge the battery as it works for a short time only when the cover is moved. It is possible that by repeatedly moving the cover, you can call an emergency service, but the problem of full recharging will not be solved.

The mechanical device is not reliable enough and after 5 ... 6 months damage to the gear mechanism is possible.

The objective of the invention is to ensure long-term recharge of the cell phone battery.

The task of creating a group of inventions is the increase in battery charging time.

Achieved technical results: increased battery charging time and increased reliability.

The solution of these problems has been achieved in a mobile communication device comprising a housing, an electronic unit connected to the battery, a speaker and a microphone located in the housing, as well as a display and a set of keys located on the front side of the housing, an electric generator connected to the battery, characterized in that the electric generator is made on the basis of mechanoelectrets and contains cells in which the goods are placed and on the walls of which mechanoelectrets are fixed, and the cells are made in the form of a parallelepiped having a base in the form of a square silt and hexagon, and all cell walls are made of electret film, on both sides of which a metallized coating is applied.

Loads can be made in the form of balls.

Loads can be made of ceramic.

Loads can be made of glass. Loads can be made of dielectric coated metal. Loads can be made of electrets. The generator can be made in the form of a stand-alone device mounted on the housing of a mobile communications device and connected by a cable to the battery of a cell phone. The electric generator can be made inside the housing of a mobile communications device and connected by wires to the battery.

The solution to these problems was achieved in a method of recharging the battery of a mobile communications device, including periodically replenishing it with generated electricity from an electric generator, in that the electric generator is based on electrets that convert mechanical energy into electrical energy, and triboelectrets are used as electrets.

Mechanical energy of vibration can be used to generate electricity. To generate electricity, the movement of moving loads in electret coated cells can be used.

Electricity generation can be carried out by pressing the keys of a cell phone equipped with electrets, for example, mechanoelectrics.

A mobile communication device (Fig. 1 ... 22) 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, a battery 8 connected by electric wires 9 with an electronic board 6, an electric generator 10, which is connected by wires 11 containing a circuit breaker 12 to the battery 8 (Fig. 1).

In this case, the electric energy generator 10 comprises a housing 13, in the cells 14 of which loads 15 are installed.

Loads 15 can be made of any material, in particular ceramic or glass. Preferably, the weights 15 are made of dielectric coated metal to prevent short circuits within the cells 14. Most preferably, the weights 15 are made of lead. In this case, the power of the generator 10 with the same Hadar will increase several times.

It is possible to use 15 pre-charged electrets as cargo material, which will additionally enhance the electric field inside the cells 14, which helps to increase the efficiency of the electric generator 10.

On all the walls of the cells 14, mechanoelectrets 16 are installed. In mechanoelectrets 16, electrical energy is generated when the electrets are deformed (from shocks). In a particular case, triboelectrets can be used in which electrical energy is generated from friction.

Cells 14 can be made in the form of a parallelepiped with a base in the form of a square (Fig. 2) or in the form of a hexagon (Fig. 3). Between the electric generator 10 and the battery 8, a converter 17 is installed, designed to reduce voltage and stabilize it.

An electret is a dielectric that maintains a polarized state for a long time after removing an external influence, which led to the polarization (or charging) of this dielectric and creates a quasi-constant electric field in the surrounding space.

A large number of materials used, methods of external influence, technological methods for creating a polarized state in dielectrics determine the variety of manifestations of the electret effect in them.

Modern ideas about the electret effect are based on two types of charges in dielectrics - hetero-charge and homo-charge. The hetero charge is due to electric polarization in the bulk of the dielectrics due to the orientation of the dipoles, ion (or electron) polarization, as well as the displacement of the space charge. In this case, the negative charge of the electret is concentrated at the anode, positive at the cathode, and the emerging electric field is opposite in direction to the polarization field.

The homo-charge is caused by the injection of charge carriers from the electrodes into the dielectric and their localization at the centers of capture or recombination of electrons and holes (energy traps) of various nature. In this case, the bound negative is located at the cathode, and the bound positive charge is located at the anode, and the resulting resulting field has the same direction as the polarizing one. The above traps are the energy levels of capture of the injected charge carriers in the band gap of a dielectric or semiconductor.

There are several ways to make electrets. Most of them are based on the fact that the dielectric is placed in an electric field and subjected to additional physical action, which reduces the relaxation time of dipoles or accelerates the migration of charged particles. Depending on the type of physical impact, thermo-, electro-, photo-, magneto-, radioelectrets, etc. can be distinguished. An electret state can also arise without applying an external electric field to the dielectric, for example, from mechanical deformation (mechanoelectrets), when the dielectric is charged in the field corona discharge (corona electrets), when polymers are heated in contact with electrodes of dissimilar metals (metal-polymer electrets), during electrification by friction (triboelectrets), under the influence of a glow discharge plasma. The electret effect is inherent in ferroelectrics (ferroelectrets), tissues of a living organism (bioelectrets). When fixing dipoles and displaced ions oriented in an electric field by chemical means, for example, by vulcanization, chemoelectrets are obtained.

The most important characteristic of electrets, determined experimentally, is the effective surface charge density (σ _eff , C / m ² ), which is equal to the difference between homo and hetero charges. Another parameter characterizing the properties of electrets is the relaxation time of charges τ _p (time to reduce the charge by e times). The life time of an electret τ _W is the period of time during which the material retains electret characteristics. For various polymers, τ _W is 3–10 years.

It is possible to install at the outlet of the generator 10 in front of the circuit breaker 12 of the energy storage 18 in the form of a capacitor (Fig. 1), to prevent overcharging of the battery 8.

In the proposed mobile communication medium, mechanoelectrets 16 are used in the form of a polymer film with a metallized coating 19 and 20 on both sides (Fig. 4). The metallized coating 19 and 20 acts as an electric bus and is intended to relieve tension from electrets and transfer it through wires 11. At the same time, due to its very small thickness, it does not prevent the deformation of mechanoelectrets 16.

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 ... 22 are not shown), and the connector 21 of the mobile communication means and the connector 22 of the electric generator 10 are connected by a cable 23 (Fig. 6). In this case, the proposed invention can be used on previously manufactured mobile communications.

In the second embodiment, the housing 20 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 cells 14 having a square (rectangular) base and cylindrical loads 15, 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 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 show an electric generator 10 with mechanoelectrets 16 in the form of triboelectrets and the installation of cylindrical weights in cells 14 without a gap. In this case, the energy is generated not from impacts, but from friction produced by loads 15.

In FIG. 16 shows a means of mobile communication, specifically a cell phone, in which the electric generator 10 is combined with the keyboard 2.

In FIG. 17 shows the electrical connection diagram of the mechanoelectrets 16 located on the end walls of the cell 14, while the wire 24 is connected to the metallized coating 19, and the wire 25 is connected to the metallized coating 20. FIG. 18 shows a diagram of the output of electric current from the generator 10. To the connector 22, which can be made coaxial, wires 24 and 25 are connected.

In FIG. 19 is a diagram of the output of electrical energy from the mechanoelectrets 16 located on the side walls of the cell 14. The potential output from these mechanoelectrets 16 is carried out by wires 26 and 27. The wires 24, 25, 26 and 27 are connected in pairs in parallel. This increases the total current and power of the generator 10, because it generates current when the housing 1 of a mobile communication device, in particular a cell phone, oscillates in any plane.

In FIG. 20 ... 22 shows a diagram of energy production in mechanoelectrets 16 in dynamics. The electric charge in the pre-charged mechanoelectrets 16 is constantly decreasing (Fig. 21), but due to the periodic shocks of the loads 15, the static electricity is again induced in the mechanoelectrets 16 (Fig. 22) and it is used to recharge the battery 8.

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 loads 15 make oscillatory movements and hit the mechanoelectrets 16, constantly generating electrical voltage in them. The current through the wires 11 is supplied to the converter 17 to reduce and stabilize the voltage and then to the battery 8 and constantly charges it. When the battery 8 is fully charged, the circuit breaker 12 disconnects the power generator 10 from the battery 8. The circuit breaker 12 can be controlled by the voltage at the output of the battery 8. (voltage measuring device in Fig. 1 is not shown).

The use of the group of inventions has significantly improved the reliability of mobile communications by increasing the battery life by hundreds and thousands of times, i.e. during the entire life of the mobile communications device without recharging from an external charging device.
