Description

"MULTIPLE BATTERY CHARGER FOR PORTABLE ELECTRONIC

DEVICES"

FIELD OF THE INVENTION

The present invention concerns a multiple battery-charger for portable electronic devices for recharging, also simultaneously, different types of portable electronic devices. In particular the present invention is applied for recharging portable electronic devices in private places or public premises such as restaurants, cinemas, theaters, private clubs or suchlike.

By portable electronic devices here and hereafter in the description and claims we mean devices fed by a rechargeable battery such as for example cell phones, multimedia readers, palmtops, portable game consoles, movie/photo cameras or suchlike.

BACKGROUND OF THE INVENTION

Battery-chargers for portable devices are known, provided with an electric connection cable, generally 1 or 2 meters long, which, connecting to the portable device and the mains, typically 220V or 120V in AC, allow to recharge the battery by converting the tension to a low continuous tension able to recharge the batteries of the portable devices.

One disadvantage of known battery-chargers is that they need to be near a socket to connect to the electric mains, and therefore they are not energy autonomous.

Multiple battery-chargers are also known, provided with a plurality of cables and/or connectors with which several electronic devices can be simultaneously connected. In some types of multiple battery-chargers, the portable electronic devices are recharged one at a time according to a predetermined sequence or, in others, the multiple battery-chargers simultaneously recharge all the portable electronic devices connected to them.

One disadvantage of the multiple battery-chargers in question is that they too, in order to recharge, must be connected to a feed source, limiting the field of use only to areas or zones where there is a mains feed socket.

Document US-A-2009/267562 describes a portable multiple battery-charger for portable electronic devices which, thanks to a lithium-ion battery, is able to provide a complete charge for two portable electronic devices, simultaneously or individually. This known battery-charger is able to simultaneously charge two devices up to three different times before having to recharge the battery-charger itself.

Document FR-A-2.939.573 describes a unit for charging a battery of a portable electronic device, provided with electric adjustment and interface connectors with the portable electronic device itself which, however, for recharging, need connecting to an external electric supply system since it does not include an accumulator.

Document US-A-2003/0141840 describes a recharging station for portable electronic devices having a plurality of electric connectors, connectable to an external network. For this known solution too, one disadvantage is that for recharging it needs to connect to an external electric supply system, since it does not provide an accumulator.

Purpose of the present invention is therefore to achieve a multiple battery- charger, energy autonomous, which is able to charge simultaneously and several times a plurality of portable electronic devices without the aid of connection to the network, and is therefore suitable for use in places such as for example bars, restaurants, clubs or suchlike where it is not always possible to have an electric socket available in the immediate neighborhood of the user.

The Applicant has devised, tested and embodied the present invention to overcome the shortcomings of the state of the art and to obtain these and other purposes and advantages.

Unless otherwise defined, all the technical and scientific terms used here and hereafter have the same meaning as commonly understood by a person with ordinary experience in the field of the art to which the present invention belongs, including the definitions.

The word "comprise" and variants of the word such as "comprises" and "comprising" are used here to indicate the inclusion of a clearly expressed whole— or clearly expressed wholes but not the exclusion of any other whole or any other wholes, unless in the context or in use an exclusive interpretation of the word is required. The present invention is set forth and characterized in the independent claim, while the dependent claims describe other characteristics of the invention or variants to the main inventive idea.

In accordance with the above purpose, a multiple battery-charger for portable electronic devices according to the present invention comprises an outer casing which delimits internally a housing compartment inside which an energy accumulator is disposed.

The accumulator is a rechargeable lead battery and is sized to allow the simultaneous recharging, for several times, of the portable electronic devices. Using a rechargeable lead battery according to the present invention has a plurality of advantages, including:

- lower economic cost, since with the same capacity a lithium-ion battery costs from 5 to 8 times more than a lead battery;

- greater safety, since lithium-ion batteries are considered Class 9 Hazardous materials, and cannot, for example, be sent by air;

- longer lasting charge, since a lead battery can keep the charge and continue functioning for many years, and even if the battery is not being used, whereas a lithium-ion battery does not have this property, as is obvious, for example, in the everyday use of cell phones or other portable devices provided with lithium-ion batteries.

A battery-charger unit is provided suitable to recharge the energy accumulator. A plurality of connection means, such as connector cables and/or sockets, are associated with the external surface of the casing, to connect the portable devices to the multiple battery-charger.

The connection means are interfaced with the energy accumulator by connection means that allow transmission and management of the electric energy.

The connection means comprise a plurality of feed units, coordinated in number with the connection means, located in parallel with respect to each other so as to allow the simultaneous and independent recharging of the portable electronic devices.

Advantageously, thanks to the appropriately sized accumulator, the multiple battery-charger according to the present invention is in turn portable and energy autonomous, even for several recharging cycles, since its functioning is independent from the mains feed during normal use. This characteristic makes the multiple battery-charger suitable for use in areas or places where mains feed sockets are not accessible.

Advantageously, the invention allows the user to stay close to his portable electronic device during the recharging, thus facilitating protection and use in any position whatsoever.

In some forms of embodiment, the energy accumulator of the multiple battery- charger is a lead battery sized to accumulate much more energy than that normally needed to recharge a single portable device.

When the internal battery of the multiple battery-charger is flat, it is sufficient to connect the multiple battery-charger for portable electronic devices to the electric mains in order to recharge it. It is therefore advantageous that the internal battery is sized so that it can give the battery-charger acceptable autonomy. To give an example, not restrictive of the field of protection of the present invention, with a single charge of the multiple battery-charger it may be possible to recharge a number of portable electronic devices comprised between 40 and 50.

The lead battery is also suitable to deliver continuous current sufficient to recharge a plurality of portable electronic devices simultaneously, and therefore equipped with adequate power.

In some forms of embodiment, the connection means of the multiple battery- charger according to the present invention comprise more than one connector and/or cable to feed the electronic devices. The connectors can be different from each other, for example, some or all can be USB type, others of a different type.

In some forms of embodiment, the portable electronic devices to be recharged can be connected to the connectors or sockets of the battery-charger by means of suitable cables, supplied with the multiple battery-charger according to the present invention or supplied with the devices themselves.

In some forms of embodiment, the multiple battery-charger may comprise retractable cables to recharge the portable electronic devices. The retractable cables can be rewound automatically inside the outer casing when it is no longer necessary to use them.

Advantageously, different connection cables can be associated with different connectors to use with rechargeable devices. To give an example, together with the multiple battery-charger a cable could be supplied with a micro USB connector, therefore suitable for connection of all portable devices equipped with connectors of this standard.

Advantageously, with the invention each individual portable electronic device connected is recharged independently of the other portable electronic devices, until the maximum recharge level is reached.

In some forms of embodiment, when the electronic device is connected to the multiple battery-charger according to the present invention, the charge status is measured, either by measuring means integrated into the device itself, or by measuring means of the battery-charger. If the charge level is not at its maximum, the process of recharging the battery begins automatically. As soon as the maximum charge level is reached, the electronic device is excluded from charging.

In some forms of embodiment, the multiple battery-charger comprises user interface means, which include signaling or display and/or interaction means.

To give an example, not restrictive of the field of protection of the invention, the signaling or display means may include a charge signaler, which indicates the charge status of the internal accumulator and signals when the autonomy of the multiple battery-charger is about to end.

In some forms of embodiment, the connection means are able to carry out the recharging of the portable electronic devices by means of an electromagnetic induction system of a known type, exploiting the proximity of the system with the electronic devices to be recharged.

To this purpose, in order to be recharged, the portable electronic devices can be equipped, internally or externally, with appropriate means for the transmission of energy by means of electromagnetic induction, therefore for example resting on, or located in proximity to, an electromagnetic induction plane of the above induction system associated with the casing of the battery-charger, where recharging can take place.

In some forms of embodiment, the multiple battery-charger is provided with signaling or display means to signal the limit of electronic devices that the battery-charger has reached. As a further variant, the signaling or display means may include an indicator of the current delivered which, instant by instant, signals the current delivered by the multiple battery-charger, relating it to a desired maximum parameter. The user can therefore establish in real time if the multiple battery-charger can support other devices to be recharged or if it is already in a condition of maximum current delivery.

In some forms of embodiment, the signaling means may include a possible external alphanumerical display, or suitable to reproduce multimedia contents, to allow communication and display of the status of the multiple battery-charger to the user, or of other information, such as for example communications of a commercial, advertising or service type. Advantageously, in some forms of embodiment, the battery-charger may be connectable, thanks to a suitable communication module, to a data network, for example Internet, from which with a wireless connection it can download and make usable the multimedia contents, advertising and service information or other.

According to a variant of the present invention, the multiple battery-charger comprises a Bluetooth ® unit, suitable to interface with other communication devices possibly connected to it.

BRIEF DESCRIPTION OF THE DRAWINGS

These and other characteristics of the present invention will become apparent from the following description of a preferential form of embodiment, given as a non-restrictive example with reference to the attached drawings wherein:

- fig. 1 is a perspective view of the multiple battery-charger for portable electronic devices according to the present invention;

DETAILED DESCRIPTION OF A PREFERENTIAL FORM OF

EMBODIMENT

With reference to the attached drawings, the reference number 10 denotes in its entirety a multiple battery-charger for portable electronic devices 16a, 16b, 16c according to the present invention.

The multiple battery-charger 10 comprises an external casing 14, which delimits internally a housing compartment 19 inside which an accumulator of electric energy 20 is disposed.

The accumulator 20 is a rechargeable lead battery. The accumulator 20 is also sized to allow the simultaneous recharging, for several times, of the portable electronic devices 16a, 16b, 16c.

A plurality of connection means, such as connectors, sockets 13 a, 13 b, 13 c, 13d and/or cables 15a, 15b, 15c, of which more will be said hereafter, are associated with the external surface 14a of the casing 14, to connect the portable electronic devices 16a, 16b, 16c to the multiple battery-charger 10.

The connection means 13a, 13b, 13c, 13d and/or 15a, 15b, 15c are interfaced with the accumulator 20 by connection means 29 which allow to transmit and manage the electric energy.

The connection means 29, in some forms of embodiment, comprise feed units 26a, 26b, 26d coordinated in number to the connection means 13a, 13b, 13c, 13d and/or 15a, 15b, 15c, located in parallel in order to allow the simultaneous and independent recharging of the portable electronic devices 16a, 16b, 16c. The feed units 26a, 26b, 26d of the portable electronic devices 16a, 16b, 16c are normally feed and management circuits of the electric parameters of the corresponding connection means 13a, 13b, 13c, 13d and/or 15a, 15b, 15c.

In some forms of embodiment (figs. 1 and 2), the multiple battery-charger 10 for portable electronic devices 16a, 16b, 16c is provided with a certain number of female USB connectors 13a, 13b, 13c, 13d and/or USB adaptor cables 15a, 15b, 15c, able to interface different portable electronic devices 16a, 16b, 16c with the female USB connectors 13a, 13b, 13c, 13d.

In order to recharge the portable electronic devices 16a, 16b, 16c it is necessary to switch on the multiple battery-charger 10 by means of a button or on/off switch 12, for example a touch type switch on button of the capacitive type, associated with the casing 14. According to some forms of embodiment, the multiple battery-charger 10 is normally in low consumption mode and when it detects the connection of a portable electronic device 16a, 16b, 16c it activates itself and begins the recharging process.

The accumulator 20 in this case is a battery (fig. 2) which supplies the energy needed for recharging the portable electronic devices 16a, 16b, 16c.

Advantageously, the accumulator 20 is a rechargeable lead battery with a tension comprised between 6V and 18V, preferably between 9V and 15V, for example 12 V. The accumulator 20 is recharged by connecting a feed cable to a recharging socket 17, associated with the casing 14, at the mains voltage of 120V or 220V. During normal use, the recharging socket 17 is disconnected from the mains electric supply, and the multiple battery-charger 10 can be used without other feed sources.

The portable electronic devices 16a, 16b, 16c connected to the multiple battery-charger 10 are advantageously recharged simultaneously, and remain in a charging condition. When the maximum charge condition is reached on the portable electronic device 16a, 16b, 16c, the multiple battery-charger 10 stops feeding it.

As shown in the form of embodiment in fig. 2, the multiple battery-charger 10 comprises a battery-charger unit 21, also housed inside the casing 14, suitable to recharge the accumulator 20 when the multiple battery-charger 10 is connected to the mains network by the recharging socket 17 as explained above.

According to some variants, the battery-charger unit 21 is instead outside the external casing 14 of the multiple battery-charger 10, and is connected to the recharging socket of the latter by means of a relative cable.

In one form of embodiment, the battery-charger unit 21 uses a switching type DC-DC circuit as an energy convertor, in order to maximize the conversion efficiency, optimize the recharging time and reduce energy dispersions to a minimum.

The multiple battery-charger 10 also comprises, inside the casing 14, a control unit 22 suitable to verify the internal circuit parameters, with a relative feed unit 23.

The accumulator 20 feeds the internal electronic circuit of the multiple battery- charger 10 and the portable electronic devices 16a, 16b, 16c.

In particular, the accumulator 20 interfaces, by means of the connection means 29, with the connection means of the portable devices, and with the control unit 22 by means of the relative feed unit 23, which converts the tension of the battery 20 into the tension required to feed the control unit 22.

The connection means 29 also comprise a tension conversion unit 24, inside the casing 14, suitable to convert the tension of the accumulator 20 into a tension, for example 5.2V, suitable to generate the potential difference needed to feed the portable electronic devices 16a, 16b, 16c according to USB standard.

Furthermore, in some forms of embodiment, the connection means 29 comprise a measuring unit 25 suitable to measure the total current intensity required by the feed units 26a, 26b, 26d of the portable devices 16a, 16b, 16c . The measuring unit 25 of the current delivered interacts with the control unit 22 which consequently manages the enablement of the feed units 26a, 26b, 26d.

In some forms of embodiment, the multiple battery-charger 10 comprises user interface means 27, for example to communicate information on the recharging status, or interaction means. In this case, the interface means 27 comprise signaling means, such as for example a visual indicator 1 1, but this could also be acoustic or mixed, which signals if the charge level of the internal battery 20 is low.

When the accumulator 20 is recharging, the indicator 1 1 is on to signal that the necessary charge has been reached.

In variant forms of embodiment, the interface means comprise interaction means, such as for example a keyboard, mouse or other. In some forms of embodiment, the signaling means comprise an external indicator 1 1a of the current delivered, associated with the current measuring unit 25, by means of the control unit 22. The multiple battery-charger 10, by means of the indicator 1 la of the current delivered, can supply information to the user concerning the current delivered instant by instant to the portable electronic devices 16a, 16b, 16c, or can signal that the maximum number of portable electronic devices 16a, 16b, 16c connected simultaneously has been reached.

In some forms of embodiment, the signaling means comprise an external alphanumerical display l ib by means of which the multiple battery-charger 10 can supply information to the user concerning the charge status of the battery 20 and/or information of other types, for example commercial, advertising or service messages.

In some forms of embodiment, the circuit parameters verified by the control unit 22 comprise one or more of the following controls: monitoring of the tension at the heads of the battery 20, the tension exiting from the feed unit 23, the tension exiting from the tension conversion unit 24, the total current absorbed by the measuring unit 25, overload control on each individual feed unit 26a, 26b, 26d, control of the presence of the portable electronic devices 16a, 16b, 16c and the complete management of the relative charging cycle, enablement of the feed on the USB connectors 13a, 13b, 13c, 13d, enablement of the tension conversion unit 24, management of the signals on the user interface 27 and other. According to some forms of embodiment of the present invention, the control unit 22, by means of the feed units 26a, 26b, 26d, obliges the portable electronic devices to assume a low consumption mode (sleep mode or stand-by) after a determinate period of non-use, to conserve the charge of the battery 20.

The multiple battery-charger 10 can also include a Bluetooth ® speakerphone unit, not shown in the drawings, to manage the speakerphone communications with a wireless connection of a standard type between the multiple battery- charger 10 and electronic telephone devices equipped with a Bluetooth ® unit.

In this way, the multiple battery-charger 10 is able, for example, to carry out a call in speakerphone mode from a cell phone connected to the battery-charger for charging. This function is useful if several users are in a place, which may be a bar, restaurant, club or other, and need to telephone a user who can speak with all of them, at the same time keeping the battery under charge.

According to some other variants, the multiple battery-charger 10 can comprise a communication module suitable at least to receive SMS (short message service) type messages, in particular those known as "premium SMS", that is, by means of which the user transmits to the multiple battery-charger 10 a text message associated with an economic counter-value in order to obtain a desired service for a determinate period of time and which, in this case, enables the functioning of the multiple battery-charger 10 for a certain period of time during which the user himself recharges the battery of his own portable electronic device.

It is clear that modifications and/or additions of parts may be made to the multiple battery-charger 10 as described heretofore, without departing from the field and scope of the present invention.

For example, according to a variant according to the present invention, the multiple battery-charger 10 may comprise a device to measure the alcohol rate.

According to other variants, to prevent the fraudulent removal of the multiple battery-charger from the position where it is being used, it may comprise an anti- shoplifting device.

The multiple battery-charger may also implement different additional functions which render it suitable for use in the places where it normally operates, such as being associated with salt- and pepper-pot holders, when used in restaurants and suchlike.

It is also clear that, although the present invention has been described with reference to some specific examples, a person of skill in the art shall certainly be able to achieve many other equivalent forms of multiple battery-charger, having the characteristics as set forth in the claims and hence all coming within the field of protection defined thereby.
