Description

FIELD OF THE INVENTION

The present invention deals with systems and methods for the collection of kinetic energy and generation of electrical energy integrated in portable electronic devices using the accelerations to which they are subject,

TECHNIQUE NOTE

The known technique in kinetic energy collection systems in portable electronic devices involves the use of expensive and inefficient piezoelectric technologies, or electromagnetic induction technologies with heavy and bulky permanent magnets, which currently preclude their implementation and widespread marketing. ,

A branch of kinetic energy collection systems in portable electronic devices involves the use of piezoelectric elements, a very expensive and inefficient technology, which exploits the deformations of said piezoelectric elements to produce a potential difference subsequently conditioned and used by the device. These piezoelectric elements in fact reach acceptable efficiency levels only in a narrow range of resonance frequencies, impossible to reach with the vibrations to which portable electronic devices are usually subjected. The use of thin-film piezoelectric elements slightly increases efficiency outside the resonance range, but exponentially increases costs, without however guaranteeing energy production that justifies them.

Another branch of solutions for the collection of kinetic energy in portable electronic devices is based on electromagnetic induction, usually using one or more magnets that oscillate with respect to the windings on which a variation of magnetic flux and consequently a current is induced. . The optimization of said electromagnetic induction systems, while providing for the suspension of the magnets with opposing magnetic fields or springs in order to exploit even small accelerations, does not produce sufficient energy unless the size of the magnets and therefore the subject oscillating mass are considerably increased. to movements. In fact, there are external generators to be applied to portable electronic devices such as smartphones, which, however, cannot find the market due to the high weight and dimensions, even if proportional to an almost acceptable energy production.

By using, on the other hand, compact electromagnetic induction systems, which can be integrated directly into the portable electronic device, there is insufficient energy production which is inadequate for the consumption of said device.

In any case, said electromagnetic induction systems would occupy precious space inside the portable electronic device, which in order to maintain the same dimensions would have to heavily sacrifice the size and capacity of the internal battery, consequently reducing the autonomy and thus missing the main purpose of the technology. or increase the autonomy of the device.

In fact, none of the technologies described so far has found a market or technological outlet.

The reason is to be found in the lack of an overall vision, in fact the kinetic collection system is always seen as a block in itself, independent of the existing device.

OBJECTIVES AND ADVANTAGES

The present invention, solution of the aforementioned problems, is characterized by an electromagnetic induction system designed to integrate with the portable electronic device to be powered,

In fact, it not only uses the magnetic field generators as an oscillating mass, but also integrates, within the oscillating mass, electrical energy accumulators and components of the device itself.

Some objectives and advantages of the present invention are;

a) increasing the energy produced by the device by integrating its components into the oscillating mass of the kinetic energy collection system, without therefore adding overall weight and bulk. The energy that can be produced is therefore scalable with the weight and dimensions of the device itself;

b) powering energy-intensive portable electronic devices and making the production of electricity proportional to the capacity of the internal electric energy accumulators, without the need to linearly increase the weight of the magnetic field generators;

c) to use magnetic field generators characterized by much lower weight, bulk and cost with respect to the solutions according to the known art;

d) to make even small accelerations usable and to dampen the acceleration peaks thanks to the suspension of the oscillating mass with mechanical energy accumulators with non-linear and progressive elastic characteristics;

e) to guarantee a useful output voltage even with small accelerations, thanks to the use of a high number of windings and pole pairs, allowed by the construction methods adopted;

f) partially absorb the energy of any impacts due to falls of the portable electronic device, reducing the probability of internal and external breakages;

g) to exploit also single impulsive accelerations thanks to the high kinetic energy that can be stored by the oscillating mass, and to the high elastic potential energy that can be stored in the mechanical energy accumulators;

h) exploit a wide range of acceleration intensities, so as to be able to produce electrical energy both with small accelerations typical of normal human activities, and when the device is specially shaken or fixed to rigid moving parts (e.g., the frame of a Mountain Bike) to generate large amounts of energy;

i) allow the integration within the oscillating mass of part or all of the components of the device, allowed by the construction methods adopted, consequently having a further increase in the energy that can be produced and protection against impacts of the device, in line with the purposes of the invention mentioned above;

l) provide solutions for power and logic connections between the external casing and the oscillating mass (e.g. springs in rameberillium alloy), so as to be able to suspend as many components as possible, limiting or completely eliminating the need to use traditional connections that would decrease the useful stroke and would be subject to repeated bending cycles and therefore to breakage;

m) to favor the triggering and maintenance of the resonance of the oscillating mass, allowed by the consistent increase of said oscillating mass and possibly by the integration of a system of variation of the electrical load or of the damping, to favor the triggering and maintenance of the resonance at frequency values compatible with those found in daily use of the device (walking, running, cycling, bus, etc.);

n) guarantee in any situation a charge necessary for use in an emergency, simply by shaking the device, providing suitable passive electrical conditioning systems also in redundancy to the more efficient active ones;

o) allow the integration in the format of any battery (eg, AA, AAA, C, D, 18650, crl23a, button batteries, non-standard proprietary formats, etc.), and integration into any device equipped with a electricity, having a moderate influence on dimensions and weight, supplying energy to each movement and allowing the device to be shaken specifically to increase the energy produced and its autonomy;

p) increasing the autonomy of said portable electronic device, increasing the time interval between recharges via the electricity network,

DETAILED DESCRIPTION - FIG. L THE PREFERRED REALIZATION

Figure 1A shows an exploded perspective view of a portable USB battery pack with integrated kinetic charging system for portable electronic devices according to a preferred embodiment of the present invention.

An outer casing (126) (127) consisting of two interlocking parts entirely contains the device.

The external casing (126) (127) provides housings for the eight sliding balls (171), the foils in ferromagnetic material (141) (142), the windings made on multilayer PCB (151) (152), the spring in copper-beryllium alloy (102) and an external circuitry (161).

The external circuitry (161) provides USB connection in and out of the external casing (126) (127), The external circuitry (161) is electrically connected to the windings made on the multilayer PCB (151) (152), and to the springs in copper-beryllium alloy (101) (102).

The copper-beryllium alloy springs (101) (102) suspend an internal support (122) (123).

The internal holder (122) (123) contains a 18650-format lithium-ion battery (111) and a battery protection circuit (163).

The internal support (122) (123) also provides sliding guides for the eight sliding balls (171) and housings for the tracks of neodymium magnets (131) (132) with alternate poles.

OPERATION - FIG.lA

The oscillating mass composed of battery (111), internal protection circuitry (163), internal casing (122) (123), traces of neodymium magnets (131) (132), is suspended through the copper-beryllium alloy springs ( 101) (102), inside the outer case (126) (127),

The conductive springs (101) (102), are installed in opposition on the same working axis, and preloaded in such a way that the preload forces cancel each other out, allowing only compressive stresses, and allowing the unbalance of the system with any external force.

The oscillating mass, guided by the eight sliding balls (171), is therefore free to move on the working axis of the conductive springs (101) (102) with respect to the windings made on multilayer PCB (151) (152) integral with the casing external (126) (127). Foils in ferromagnetic material (141) (142) are positioned on the windings made on multilayer PCB (151) (152) on the opposite side of the traces of neodymium magnets (131) (132), in order to increase the density of the lines of magnetic field near the windings made on multilayer PCB (151) (152),

Furthermore, each movement of the oscillating mass involves the compression of one of the conductive springs (101) (102) and therefore an accumulation of elastic potential energy.

By applying an acceleration to the outer casing (126) (127), a consequent acceleration of the internal oscillating mass is caused and therefore an imbalance of the system and a movement of the oscillating mass. The kinetic energy accumulated by the oscillating mass is partially converted into electrical energy using the variations of magnetic flux on the windings made on multilayer PCB (151) (152) and partially accumulated again in the conductive springs (101) (102) in the form of energy elastic potential.

With respect to the prior art, it is therefore possible to increase the kinetic energy that can be accumulated in the oscillating mass, thanks to the increase in the force acting on it, a direct consequence of the increase in the oscillating mass.

The elastic potential energy accumulated by the conductive springs (101) (102) is cyclically reconverted into kinetic energy and therefore electrical energy.

The electrical energy coming out of the windings made on the multilayer PCB (151) (152) is subsequently conditioned by the external circuitry (161) and transferred through the conductive springs (101) (102) to the internal protection circuitry (163). If the internal protection circuitry (163) does not detect anomalies in temperature, voltage and current, it accumulates electrical energy in the battery (111).

By connecting an external device to the USB port integrated in the external circuitry (161), the electrical energy supplied by the battery (111) is conditioned to voltage levels compatible with USB standards by the external circuitry (161). The internal battery (111) can also be recharged via a USB power supply connected to a female micro-USB port placed on external circuitry (161),

The FIGS. 2A-2B-2C-2D show a series of perspective views of a portable USB battery pack with integrated kinetic charging system for portable electronic devices according to a preferred embodiment of the present invention.

FIG. 2A shows an outer casing (226) (227) consisting of two parts which entirely contains the device.

Said external casing (226) (227) provides: recesses (276) for the four sliding balls (271), guides (277) for the four ball bearings (272), housing for the external circuitry (261), of the joints for the springs in copper-beryllium alloy (203) (204), of the joints (286) for the windings made on multilayer PCB (251) (252).

The external circuitry (261) provides USB in and out connection through the external shell (226) (227).

FIG. 2B shows the casing of the external circuitry (261) which provides two joints (289) (290) which electrically constrain and connect the windings made on the multilayer PCB (251) (252).

The external circuitry (261) furthermore provides some notches for the conductive springs (201) (202).

The conductive springs (201) (202) are connected and wedged to the casing of the internal circuitry (262).

The casing of the internal circuitry (262) provides for an interlocking with relative contacts (299) for the electrical connection with the casing of the batteries (222) (223) through the appropriate connector (292).

The casing of the internal circuitry (262) and the casing of the batteries (222) (223) have sliding guides for the four balls (271),

FIG. 2C shows the battery case (222) (223), with slots for the snap-in system.

The battery case (222) (223) contains and holds the battery holders (219) (220), ferromagnetic foils (241) (242), and batteries (211) (212),

The battery holders (219) (220), contain the batteries (211) (212) and provide a housing for the trace of neodymium magnets (231), and two housings for the ferromagnetic material sheets (241) (242) ,

The foils in ferromagnetic material (241) (242) have supports with relative holes for locking the four ball bearings (272),

Figure 2D shows the exploded view of the entire device.

OPERATION - FIGS. 2A-2B-2C-2D

The oscillating weight comprising: battery casing (222) (223), battery holders (219) (220), two batteries (211) (212), trace of neodymium magnets (231), foils in ferromagnetic material (241) (242), four ball bearings (272) and their fixings, internal circuitry (262) and internal circuitry housing (262), is suspended through the conductive springs (201) (202) (203) (204), at the inside the outer casing (226) (227).

The conductive springs (201) (202) (203) (204), are installed in opposing bent tiles on the same work axes, and preloaded in such a way that they can be stressed only by compression, and allow the unbalance of the oscillating mass with any force external.

The oscillating mass, guided by the four ball bearings (272) and by the four balls (271), is therefore free to move parallel to the working axes of the conductive springs (201) (202) (203) (204) with respect to the windings made on multilayer PCB (251) (252) integral with the external casing (226) (227). The low friction sliding systems must respond exclusively to external accelerations thanks to the inclusion of the ferromagnetic material sheets (241) (242) in the same support structure as the neodymium magnet track (231), so that the force of attraction between the trace of neodymium magnets (231) and the sheets of ferromagnetic material (241) (242) discharges on the structure of the battery support (219) (220), instead of on the four ball bearings (272) and on the four sliding balls (271),

The internal dynamics of the device subject to external accelerations and the consequent generation of electrical energy are equivalent to those described in FIG.1A, however, thanks to the increase in oscillating mass due to the insertion of more components inside it, the production of electrical energy is greater.

The electrical energy coming out of the windings made on multilayer PCB (251) (252) is subsequently transferred through the conductive springs (201) (202) and conditioned by the internal circuitry (262) and transferred through the connectors (299) (292) to the batteries (211) (212) where it is stored.

By connecting an external device to the USB port integrated in the external circuitry (261), the electrical energy supplied by the batteries (211) (212) is transferred through the conductive springs (203) (204) and conditioned by the external circuitry (261) to voltage levels compatible with USB standards,

Internal batteries (211) (212) can also be recharged via a USB power supply connected to a female micro-USB port placed on external circuitry (261),

Consistently with what is explained in the present invention with regard to the power / weight and power / size ratios, with respect to the known art, it is evident that by increasing the electrical energy that can be stored in the device, the production of electrical energy of the device itself is also increased.

- - Conclusion, ramifications and scope

We can therefore note that in the preferred embodiments shown up to here, the kinetic charge system object of the present invention is integrated within the devices to be powered, producing, with respect to the known art, more energy with the same dimensions and weight of the device itself.

From FIGS. 1A and 2A-2B-2C-2D it can be noted that, contrary to the known technique, the kinetic charge system of the present invention is characterized by the fact that the energy production is proportional to the capacity of the internal batteries of the device, thanks to the integration of the batteries themselves in the oscillating weight.

From FIGS. 3A-3B-3C-3D we can see how the kinetic charge system object of the present invention can be integrated into thin portable devices by replacing it with the battery that powers them.

This method of integration is characterized by the fact that the devices to be powered do not undergo any changes other than the replacement of the internal battery, making the kinetic charging technology object of the present invention applicable to any existing portable electronic device, without significantly affecting, as instead happens in the known art, on the weight and dimensions of the mobile device and therefore on the capacity of the original battery of the device itself.

We can also note how by following the concept of increasing the oscillating mass through the integration of components of the device to be powered, it is possible to arrive at the total integration of the device itself within the oscillating mass, as shown in FIGS.4A-4B and FIGS.5A -5B, thus increasing the energy that can be produced.

In FIGS. 4A-4B and FIGS.5A-5B, we can also note that, thanks to the insertion of the smartphone inside the oscillating weight, the protection provided by the case is far superior compared to existing smartphone protection solutions, thanks to the fact that the energy of a possible fall is absorbed by the suspension system and then converted into electricity, reducing the risk of the smartphone being damaged,

In the preferred embodiments shown in FIGS. 2A-2B-2C-2D, FIGS, 3A-3B-3C-3D and FIGS.4A-4B the kinetic charge system object of the present invention is characterized by a support on which the traces of neodymium magnets and the foils are constrained made of ferromagnetic material, in such a way that the magnetic attraction forces are discharged on said support rather than on the sliding systems, which can therefore be undersized with respect to the solutions shown in FIG.1A and FIGS.5A-5B.

The kinetic charge system object of the present invention can be realized with variations with respect to the preferred solutions shown in FIG. 1A, FIGS, 2A-2B-2C-2D and FIGS.3A-3B-30-3D, providing for a further increase in mass oscillating through the inclusion of all the circuitry inside the oscillating mass, it will be possible to supply voltage values compatible with the device to be powered by means of electrical connections between the internal and external casing.

The constructive solutions with magnetic suspension such as the one shown in FIGS.5A-5B can provide for the complete detachment of the internal casing and therefore of the device.

In fact, as shown in FIG.6A, a variant of the preferred constructive solution shown in FIGS.5A-5B is proposed where the internal casing is designed so as to incorporate within its structure the foils in ferromagnetic material, the windings made on PCB multilayer.

In this way, the device inserted in the internal casing can be used without being contained in the external casing. If necessary, when you need to recharge the internal battery of the smartphone, the two parts can be brought together and the kinetic charge system can be reassembled to generate electricity,

In some constructive solutions such as those shown in FIGS.4A-4B, FIGS.5A-5B and FIG.6A to operate with devices equipped with buttons on areas other than that of the display, it is possible to install mechanical references between 1 ' outer casing and the inner casing so as not to interfere with the relative movement between the latter.

The linear electric mechanical conversion system used in the preferred constructions analyzed up to now can be replaced with a rotary electric mechanical conversion system, where the reciprocating linear motion of the oscillating mass is converted into rotary motion by any mechanical transmission,

Two examples, by way of non-limiting example of mechanical transmission and rotary generator are shown in FIGS.7A-7B.

Each constructive variant of the kinetic charge system object of the present invention can be implemented with a circuitry for varying the electrical load on the electrically conductive windings, which facilitates the triggering and maintenance of the resonance of the oscillating mass according to the external accelerations, increasing the efficiency of said kinetic charge system.

To modify the resonant frequency of the oscillating mass and make it compatible with the frequencies found in the different types of human activities which vary according to the type of user of the portable electronic device, the oscillating mass can be increased by adding appropriate additional materials with high specific weight and / or by varying the elastic characteristics of the mechanical energy accumulators.

It is possible to realize constructive solutions of the kinetic charge system object of the present invention using any type of electrically conductive windings, which are best suited to the shape and arrangement of the magnetic field generators and to the shape of the device,

To generate the necessary magnetic field, it is possible to use permanent magnets made of different alloys and with various internal structures, such as permanent magnets with nanocomposite structure,

The magnetic field generators can be made through electrically conductive windings used as inductors, controlled by an electronic system that excites them when the portable electronic device is accelerated enough to produce more energy than that dissipated by the excitation of the inductors themselves. This type of inductor magnetic field generators is particularly useful for extremely compact constructions.

It is possible to create a hybrid system composed of permanent magnets, which deal with the conversion of small accelerations and an active inductor system that is activated for greater accelerations.

To further increase the intensity of the magnetic field to which the armatures are subjected, it is possible to replace the sheet made of magnetic iron material with other magnetic field generators installed in order to maximize the intensity of the magnetic field lines in the vicinity of the armatures themselves.

The suspension of the oscillating mass can be achieved through mechanical energy accumulators of any material and of any shape and size, in order to adapt to the mechanical and economic characteristics required by the specific application.

A type of suspension can include a series of leaf springs sized in such a way as to have a progressive elastic modulus to be able to guarantee both useful displacements with small accelerations, and a considerable accumulation of elastic potential energy at the end of the stroke.

A further constructive feature of the springs can be the realization in plastic material that would allow their production directly by injection molding, resulting preconnected to the internal and external casing in order to reduce production and assembly costs, providing if necessary appropriate alternative electrical connections. ,

The electrical connection channels between the external casing and the internal casing can include, in addition to conductive springs, cables, contacts, sliding contacts and other types of connections useful for increasing the logic and power communication channels between said casings "

In order to increase the oscillating mass as much as possible, a pushed integration of the functional components belonging to the device to be powered is possible.

In the case of a smartphone, the glass, the display, the frame and the rear cover can be linked to the external casing, and the remaining functional components of the device can be integrated into the oscillating mass, consisting of: motherboard, antennas, input peripherals, output and all the internal electronics of the device,

This arrangement of the components in addition to increasing the oscillating mass has some advantages including: mechanical stabilization of the camera and reduction of the maximum force acting on the external casing in the event of a fall of the device.

The construction solution explained for the smartphone can be iterated for other portable electronic devices such as: notebooks, tablets, hearing aids, smartwatches, flashlights, etc.

The kinetic charge system object of the present invention can be applied to devices powered by different electric energy accumulators, such as for example;

capacitors, aluminum ion batteries, lithium polymer batteries, lithium-iron batteries and lead gel batteries (useful for further increasing the oscillating mass), etc.

One possible application could be in portable USB chargers with graphene supercapacitors.

A variant of the kinetic charge system object of the present invention, in the case in which there is no need to collect the energy of small accelerations, provides for the replacement of the mechanical energy accumulators with suitable electrical connections.

An application example could include the integration of the kinetic charge system without mechanical energy accumulators in a smartwatch where the armatures can also be powered to induce vibrations of the oscillating mass and therefore communicate with the user through vibrations and / or acoustic signals generated by the impact of the oscillating weight with special limit switches.

Although the reported descriptions contain many specificities, these should not be regarded as limitations of the scope of the invention but merely as illustrations of some preferred embodiments of the present invention.

For example, the internal and external casings of the USB battery pack can be made in other shapes such as circular, oval, trapezoidal, triangular, polygonal, arbitrary shapes, etc., and can be made in different materials such as aluminum, steel, wood etc ,, and / or inserted inside another casing also made with different materials.

The present invention has been described by way of illustration, but not of limitation, according to its preferred embodiments, but it is to be understood that variations and / or modifications may be made by those skilled in the art without thereby departing from the relative scope of protection, as defined from the attached claims,
