Description

DESCRIPTION
"System for power generation and storage for portable electronic devices"
~k ~k ~k
The present invention relates to a system for power generation and storage for portable electronic devices.
In particular, the present invention relates to a system for power generation and storage for portable electronic devices, of the type suitable to convert kinetic energy into electric energy.
As it is known, system for storing kinetic energy for portable electronic devices using piezoelectric technologies are well known. These systems exploit the deformations of said piezoelectric elements to produce a voltage difference subsequently conditioned and used by the device. Such systems, however, reach acceptable levels of efficiency only in a narrow range of resonant frequencies, impossible to achieve with the vibrations to which portable electronic devices are usually subject. The use of thin- film piezoelectric elements slightly increases the efficiency outside the resonance range, but exponentially increases the cost, without, however, guarantee high energy productions . Other energy harvesting systems for portable devices use electromagnetic induction technology with permanent magnets, which are quite heavy and bulky. Typically one or more magnets are used, the magnets oscillating with respect to the windings on which a magnetic flux variation and therefore a current is then induced. Such electromagnetic induction systems can be made considerably more efficient by increasing the size of the magnets, but this requires to use external generators to be applied to portable electronic devices, such as smartphones . These systems are, however, out of the market due to the high weights and dimensions .
A first known solution has been described, for example, in US Patent 8,975,764 granted March 10, 2015, which describes an electronic cigarette able to generate power by using the power stored within a portable power collector integrated in the cigarette. The energy is generated using the movement of a magnet placed close to a coil in which generates electrical power. This current can be converted into electric power to be stored. The movement of the magnet can be achieved by shaking or rotating the electronic cigarette. This solution has to increase the dimensions and the weight of the magnet to increase the produced power. The power generated by means of magnets having dimensions compatible with the dimensions of the device is very much lower than the power used normally by a device configured to vaporize the substances to inhale, for example trough Joule effect, making very inefficient the kinetic energy harvesting integration in the device.
A second solution is described in US patent 5,905,359 granted May 18, 1999, which describes a portable electric device that uses part of the energy by mechanical means having a rotating battery that provides power and acts as a power harvesting mechanism.
However, the latter technology has the purpose to rake kinetic energy within a flywheel, with the aim of making more regular the output of which supply the load, facilitate the conversion into electrical energy, and facilitate the use by the user. For the same user input, an increase of the battery ground does not therefore leads to an increase of the output power, but solely to a smoother implementation and design of a more simple electrical generator .
The object of the present invention is to provide a system for power generation and storage for portable electronic devices able to increase the energy generated with the increase of energy generation mass without increasing the dimensions of the magnet for generating energy, having, therefore, characteristics such as to overcome the limitations which still influence the power generation and storage systems with reference to the known technique .

With reference to Figures 1-4, a system for power generation and storage for portable electronic devices is shown, according to the invention.
More in detail, according to a first embodiment, with reference to Figure 1, the system 100 for power generation and storage for portable electronic devices comprises: an oscillating mass configured to oscillate along its translational axis passing from a first to a second end of the mass; first elastic means 101 coupled to the first end of the oscillating mass and second elastic means 102, for example made of copper-beryllium alloy, coupled to the second end of the oscillating mass in order to determine its linear oscillation along its translational axis; first magnetic means 141 and second magnetic means 142, for example ferromagnetic plates, coupled respectively to first windings 151 and second windings 152, for example made of multilayer PCBs; sliding means 171, for example eight ball, for the sliding of the oscillating mass with respect to the first magnetic means 141 and the second magnetic means 142; an outer casing composed by a first portion 126 which accommodates the first magnetic means 141 and the first winding 151 and a second portion 127 which accommodates the second magnetic means 142 and second windings 152; an external circuitry 161 electrically connected to the oscillating mass by means of the windings 151, 152 and configured to provide USB connection in input and in output from the outer casing.
According to an aspect of the invention, the oscillating mass comprises: an energy accumulator or battery 111, such as a USB portable battery pack; an inner holder containing the battery 111, formed by a first portion 122 and a second portion 123 coupled and closable on the first portion 122 provided with sliding guides for the sliding means 171, 172; first magnetic means 131 and second magnetic means 132, for example traces of neodymium magnets in alternating poles, and accommodated in suitable housings present on the outer surfaces of the portions 122, 123 of the internal support; and a circuitry 163 for protection of the internal battery 111.

According to another aspect of the invention, the casing includes housings for the eight scroll balls 171, the ferromagnetic plates 141, 142, the windings made of multilayer PCBs 151, 152, the copper-beryllium alloy springs 101, 102 and the outer circuitry 161.
In use, a user of the portable electronic device, moving it, determines an oscillatory movement of the oscillating mass along its axis of translation, thanks to the action of the beryllium copper alloy springs 101 and 102, which are installed in opposition on the same working axis, and pre-loaded so that the preload forces will reverse, allowing only to be subject to compressive stress in response to an external force. The oscillating mass, led by the eight scroll balls 171, begins to slide with respect to the outer casing, in which are located the ferromagnetic plates 141, 142 and the electrically conductive windings 151, 152. In this way, the neodymium magnets 131, 132 interacting with the ferromagnetic plates 141, 142, generate a magnetic flux that generates electrical energy in the windings made of multilayer PCBs 151, 152. The electric power generated recharges the battery passing from the external circuitry 161 and, via the conductive springs 101, 102, the protection circuitry 163 that accumulates the energy for the power of the battery 111. Moreover, elastic potential energy, following the movement of the mass, is accumulated that is converted into kinetic energy in the springs 101 and 102 and, again, into electrical energy.
Advantageously according to the invention, by increasing the oscillating mass, the cumulative kinetic energy in oscillating mass is increased and, consequently, the available electrical energy for charging the battery 111.
Therefore, by connecting an external device to the integrated USB port in the outer circuitry 161, the electrical power supplied from the battery 111 is conditioned to voltage levels compatible with the USB standard from the external circuitry 161.
Advantageously according to the invention, the internal battery 111 is rechargeable also via a USB power adapter connected to a micro USB female port on the external circuitry 161.

Advantageously according to the invention, by means of the conductive springs 201, 202, 203 and 204, the oscillating mass is suspended within the outer casing.
According to an aspect of the invention, as shown in Figure 2A, the outer casing portions 226 and 227 internally include laterally four recesses 276, two on each side, for the four scroll balls 271 of the oscillating mass and vertical guides 277 for four ball bearings 272. In addition, each portion 226 and 227 includes: an upper housing for the external circuitry 261; and, inferiorly, joints for copper beryllium alloy springs 203 and 204 and joints 286 for first windings 251 and second windings 252, for example made of multilayer PCBs.

Also, the external circuitry 261 provides joints for conductive springs 201 and 202.
According to another aspect of the invention, the casing of the internal circuitry 262 positioned on the upper part of the inner casing constituted by portions 222 and 223 provides for an interlocking 299 with relative contacts for electrical connection with the portions 222 and 223 via an appropriate connector 292 present in the upper part of the portion 222.

Even in this embodiment, the conductive springs 201, 202, 203, 204, are installed in opposition on the same working axis, and preloaded so that are subject to pressure loading, due to an external force.
In use, a user of the portable electronic device, moving it, determines an oscillatory movement of the oscillating mass along its axis of translation, thanks to the action of the beryllium copper alloy springs 201, 202, 203 and 204. The oscillating mass, driven by four ball bearings 272 and the four scroll balls 271, begins to slide with respect to the windings 251, 252 integral with the outer casing. Therefore, the interaction of the ferromagnetic plates 241, 242 with neodymium magnets generates a force of attraction discharged entirely on the holders 219 and 220.

Moreover, elastic potential energy is accumulated in the springs 201, 202, 203 and 204 and, following the movement of the mass, is converted into kinetic energy and, again, into electrical energy. Connecting an external device to the integrated USB port in the outer circuitry 261, the electrical energy supplied by the batteries 211 and 212 is transferred through the conductive springs 203 and 204 and conditioned by the external circuitry 261 to voltage levels compatible with the USB standard.
Advantageously according to the invention, the internal batteries 211 and 212 can also be charged via a USB power supply connected to a micro USB female port located on the outer circuitry 261.

The generated electric power charges the battery through the external circuitry 561 and, via the conductive ball bearings 571 and the connecting means 502, stores the energy in the battery 511. By connecting an external device to the integrated USB port in the external circuitry 561, the electric power supplied by the battery 511 is transferred through the conductive ball bearings 571 and the connecting means 502, and subsequently conditioned by external circuitry 561 to voltage levels compatible with the USB standard.

To further increase the intensity of the magnetic field which are applied to the armatures, it is possible to replace the foil in the magnetic iron material with other magnetic field generators installed so as to maximize the intensity of the magnetic field lines in the vicinity of the armatures themselves.
Advantageously according to the invention, the position of the armatures and of the magnetic means can be reversed, making the armatures integral with the oscillating mass, rather than to the outer casing, to meet special construction requirements, or when the weight of the armatures is greater than the weight of the magnetic means, thus being advantageous from a point of view of energy production.
