Description

UNIVERSAL INDUCTIVE CHARGING SYSTEM FOR A PORTABLE ELECTRONIC DEVICE

The present invention relates to a portable electronic device stand having an integrated battery, the stand forming part of a system for inductively charging a battery of the electronic device. This charging system is applicable to a selection among a number of portable electronic devices, and thus the term universal applies to this selection.

The inductive charging system includes at least one induction coil and the portable electronic device includes at least one receiving coil or induction coil. The induction coil or coils are electrically insulated from the receiving coil or coils. Energy is transferred by electromagnetic coupling between the induction coil and the receiving coil to create an induced current in the receiving coil, which is used to charge a battery or batteries in a portable electronic device.

The portable electronic device is advantageously a mobile phone, but may also be, but is not limited to, a personal digital assistant, an audio and/or video player, a graphics tablet or a navigation device.

The charging system includes a flat receiving face upon which an induction coil or coils rests. The portable electronic device rests on this receiving surface, typically the backside of the device resting on this receiving surface. The stand is relatively flat and takes the form of a pedestal specifically dedicated to one type of portable electronic device, since the charging system is intended to be universal to this selected one by inductively charging a portable electronic device of different dimensions. do not take

The efficiency of electromagnetic coupling between the inductive coil and the inductive receiving coil depends on the precise alignment of these coils and the small distance separating them. The fact that the receiving surface formed by the charging system does not have a pedestal means that the alignment between the induction coil and the receiving coil is not mechanically ensured.

There are mainly three systems for inductive charging of mobile phone type portable electronic devices that can be used in automobiles.

A first inductive charging system includes a stand having an element securing the portable electronic device in place for centering the portable electronic device in a charging position relative to a single induction coil comprising the system.

The second charging system is a system having multiple induction coils that charge the battery of the portable electronic device regardless of its position on the system stand.

The third charging system includes an induction coil that can be moved to be positioned relative to a receive coil of the portable electronic device once the portable electronic device is placed on a stand provided by the charging system. Not only a detecting element for detecting the receiving coil must be present in the system, but also a moving element for moving the induction coil must be present in the system, these moving elements being guided by the control device according to data provided by the detecting element.

However, these three charging systems have their own drawbacks and do not provide an optimal price/quality ratio.

The first system is certainly economical, but not very efficient. This requires the participation of the user, which is particularly detrimental when the user is the driver of the car, and should be avoided as this participation can be distracting.

A second system with a large number of induction coils is expensive. Furthermore, this second system does not guarantee an optimal electromagnetic coupling between the induction coil of one of the induction coils and the receiving coil carried by the electronic device.

The third system is accurate and ensures good electromagnetic coupling between the receiving coil carried by the electronic device and the induction coil of the system. However, this is very complicated to implement, very expensive, and relatively not very robust, and the moving element of the induction coil and the detecting element for detecting the position of the receiving coil are easily degraded to give an erroneous indication as to the position of the receiving coil. can

In this third system, the detection element comprises in practice equipping the system with a receiving area of the electronic device which ensures optimal detection of the detection element. This receiving area is brittle and can be easily damaged.

A key task of the present invention is to ensure that the electronic device and the charging device are aligned to provide inductive charging without having the disadvantages of conventional charging systems, thereby ensuring that the electronic device is selected from among different portable electronic devices that can be easily adapted to each electronic device. To design an induction system for charging a battery or batteries of an electronic device.

The present invention provides an inductive charging system for a portable electronic device of a selected one of portable electronic devices of different dimensions, the system comprising at least one induction coil and a stand having a receiving surface to which a device comprising a receiving coil is applied. wherein the device is positioned on the receiving surface such that the induction coil of the system and the receiving coil of the particular device are in electromagnetic contact, the receiving surface comprising a plurality of series of tabs, each series at least discontinuously define a perimeter corresponding to each device of a selected one of the devices, the tabs of each series projecting from the receiving surface in a first position, the tabs of each series comprising: wherein each tab is movable from the first position to a second position wherein each tab is retracted into the receiving surface under application of a force corresponding to the force exerted on the tab by the respective device when applied to the receiving surface. It relates to the charging system.

The technical effect is to obtain the effect of accurately and stably centering the position of the portable electronic device on the charging system. The charging system has a plurality of series of tabs, each series configured to match at least one portable electronic device. When the portable electronic device is placed on the receiving surface, the tabs of the series of tabs specific to the device are retracted as well as the series of tabs specific to the smaller dimension device are retracted. On the other hand, another series of tabs specific to the larger dimension device are held protruding to form a stop that prevents movement of the portable electronic device in the receiving surface.

Centering the portable device to the charging system is made precise by providing at least one series of device-specific tabs on the receiving surface of the charging system. The user can roughly know where he should place his portable device on the charging system, and it is understood that the series of protruding tabs provide the user with a means of visual assistance.

The centering is also stable due to restricting movement of the portable device by another series of not yet retracted tabs, which non-retracted tabs form a stop that prevents the portable electronic device from moving. . Thus, an efficient means of optimally positioning a device forming part of a selected one of the devices in the charging system is obtained at a reasonable cost. The positioning according to the invention does not require complicated means for detecting the position of the induction coil in the portable device, and as in many positioning modes according to the prior art, moving the coil in the charging system or even in the device. It doesn't even ask for a means to do it.

Here, the tab may take various forms. For example, the tabs may have several dimensions of width and length. Various types of taps may be used to delimit a contour corresponding to a particular electronic device, and such contours may be discontinuous just as easily as they may be continuous.

In a non-limiting embodiment of the invention, each of the tabs may be in the form of a pin having a rounded tip retractable into the interior of the system when a portable electronic device is placed thereon. The various series of pins form a discontinuous contour that corresponds to the contour of the associated electronic device.

Advantageously, a return element associated with each tab pushes the tabs from the second position to the first position, and the force of the return element applied to the tab is applied to the respective device when applied to the receiving surface. smaller than the force applied to the tab by the The tabs therefore always protrude when no force is applied. Thus, outlines of various electronic devices are formed in the receiving surface of the charging system.

Advantageously, each series of said tabs corresponding to each device defines a rectangular area between said tabs, the perimeter formed by said tabs on a longitudinal or lateral side of said rectangular area extending in the longitudinal direction of said receiving surface or symmetrically with the perimeter formed by the tabs on the longitudinal or lateral side respectively opposite to the lateral median axis.

The rectangular shape is the most commonly used shape for portable devices, although the invention is not limited to this shape. The rectangular regions surround each other, which can be used as a visual aid for a user when centered the portable device on the receiving surface of the charging system. The same effect can be achieved with a series of concentric taps.

Advantageously, each tab of each series of tabs is arranged in a longitudinal direction of said rectangular region when arranged laterally of said rectangular region, or laterally of said rectangular region when arranged on a longitudinal side of said rectangular region. , aligned with one or more respective tabs of one or more series of tabs located on the same side of the rectangular area. Thus, the outline of each portable device associated with the series of tabs is visible in the receiving surface when the device is not lying therein.

Advantageously, said tabs of a series of tabs have a smaller protrusion height than said tabs of a series of tabs which are more external to said rectangular area on the same side of said rectangular area. The portable device can be raised slightly, for example, by the action of a series of tabs that correspond to a smaller sized device and are already retracted. This problem can be foreseen by providing the receiving surface with tabs whose height increases with increasing distance from the interior of the receiving surface.

Advantageously, the aligned tabs of an adjacent series of tabs are immediately adjacent or are separated by a narrow spacing, the aligned tabs of the adjacent series forming a tier or in the form of a blade, the rectangular area The taps of the same series on the same side of are optionally separated by an interval.

Advantageously, said tabs of the same series of tabs on one side of said rectangular region are paired by a linking element with said tabs of the same series symmetrical to those on the other opposite side of said rectangular region ), when the tab on one side of the rectangular region moves inward, the symmetrical tab on the other side of the rectangular region moves correspondingly.

Advantageously, said tabs of said series of tabs have a free end inclined towards the interior of said receiving area. This allows for a better grip of the portable device when inserted between tabs of an associated series of tabs, and an adjacent series of tabs further from the middle of the rectangular area than the series retracted by placing the device on the device can be prevented from going out in a direction perpendicular to the rectangular area.

The present invention also provides an assembly for receiving such an inductive charging system for an electronic device, said assembly comprising an element for creating an air circulation, said air entering said charging system through said tabs in a retracted position and thereby It relates to the assembly, characterized in that discharged from.

A secondary advantage of the present invention over prior systems is that the slots provided for drawing the tabs into the interior of the system also help to ventilate the interior of the filling system and thus cool the interior of the filling system inlet and outlet. that it can be used as

The series of tabs having a passage through the slot of the charging system thus perform a dual function: a first function is that the portable electronic Optimal positioning of the device, the second function being an auxiliary function of ventilating the interior of the charging system. This provides an economical means to achieve two different functions.

Advantageously, said assembly is a passenger compartment of a motor vehicle and the element for creating air circulation is a ventilation duct opening to the passenger compartment or fan. The charging system advantageously supports an electronic device lying horizontally on a console, on a front shelf running along the vehicle windshield, in particular in a flat receptacle supported by a shelf, or on the face of a charging system stand. It may be located in the vicinity of the gear shift lever between the seat of the seat and the front passenger seat, but is not limited thereto. The charging system may be permanently integrated into one of these elements or may be removable.

3 and 4 schematically through a charging system for a portable electronic device according to the invention, showing an embodiment of a device connecting in pairs two tabs arranged on both sides of the receiving surface of the charging system; It is a cross section.

The drawings are given by way of illustration and do not limit the invention. The drawings constitute schematic outline representations intended to facilitate understanding of the present invention and are not necessarily to scale in actual application. In particular, the dimensions of the various elements illustrated may not represent actual dimensions.

In the following, reference is made to all drawings together. When reference is made to a specific figure or figures, the figures are referenced together with other figures to understand the numerical reference to which they are assigned.

With reference to all the drawings, and more particularly with reference to FIGS. 1 and 2 , the present invention relates to a portable electronic device 2 of a selected one of portable electronic devices of different dimensions (eg, not shown in FIGS. 1 and 2 ). not) for an inductive charging system (1). The system 1 comprises at least one induction coil. There may be a single induction coil or multiple induction coils, eg, a central coil surrounded by a number of other coils.

The charging system 1 has a receiving surface 3 on which a selected one of the portable electronic devices 2 (see FIG. 4 ) is applied. This portable electronic device 2 comprises a receiving coil, wherein the device 2 has the induction coil of the charging system 1 and the receiving coil of the device 2 advantageously an induction coil or an induction coil of one of the induction coils. and positioned on the stand to achieve optimal electromagnetic contact. This inductively charges the battery or batteries embedded in the portable electronic device 2 .

According to the invention, the receiving surface 3 of the filling system 1 comprises a plurality of series of tabs. Each series of tabs at least discontinuously define a perimeter of each device of a selected one of the portable electronic devices. Each series of tabs 41 to 43 ; 51 , 52 ; 61 to 63 ; 71 , 72 protrudes from and faces the receiving surface 3 in the first position. Each series of tabs 41 to 43 ; 51 , 52 ; 61 to 63 ; 71 , 72 moves from this first position to each tab 41 to 43 ; 51 , 52 ; 61 to 63 ; 71 , 72 on the receiving surface. (3) is movable to a second position retracted therein.

1 and 2 , reference is made to a single tab per series of tabs, which is either lateral tabs 41 to 43 ; 61 to 63 arranged on the lateral side of a rectangular area surrounded by a specific series of tabs; or longitudinal tabs 51 , 52 ; 71 , 72 arranged on the longitudinal side of the rectangular region. However, the shape of the area defined by a specific series of tabs is not limited to a rectangular shape.

This retraction, when applied to the receiving surface 3 , is a force corresponding to the force exerted on these tabs 41 to 43 ; 51 , 52 ; 61 to 63 ; 71 , 72 by the portable electronic device 2 specified in the series. takes place under the permission of Accordingly, when a portable electronic device 2 selected by the user in a selected one of the portable electronic devices is applied to the receiving surface 3 and a weight is placed on the receiving surface 3, the The tabs 41 to 43 ; 51 , 52 ; 61 to 63 ; 71 , 72 are retracted and re-entered into the charging system 1 . The other tabs remain generally in place except when linked between both tabs for a defined area as described below.

For example, there may be two or three series of tabs surrounding each other, each series corresponding to a portable electronic device 2 that may be selected from among at least three devices. Other numbers are also possible.

It is of course also possible for the tabs 41 to 43 ; 51 , 52 ; 61 to 63 ; 71 , 72 to return to the first protruding position. To do this, the return element associated with each tab 41-43; 51, 52; 61-63; 71, 72 removes the tabs 41-43; 51, 52; 61-63; 71, 72 from the second position. Push to position 1.

The force of the return element applied to the tabs 41 to 43; 51, 52; 61 to 63; 71, 72 is related to the tabs 41 to 43; 51, 52; 61 to 63; 71; tabs 41 to 43; 51, 52 by means of a portable electronic device 2 specified in the series of tabs when applied to the receiving surface 3, in order to cause the series of 72 to be retracted from the first position to the second position; 61 to 63; 71, 72).

A device of large dimensions causes not only the series of related tabs to be reentrant, but also the series of tabs that it encloses, with the spring calibrated appropriately considering that this series of enclosing tabs is associated with a smaller device. should be Thus, when positioned on the receiving surface 3 of the charging system 1 , this device is subjected to the return force of a number of springs of different series of tabs.

The return element is advantageously incorporated into the charging system 1 . These return elements act to return the protruding tabs 41 to 43 ; 51 , 52 ; 61 to 63 ; 71 , 72 , as are frequently the springs under the keys of many electronic devices 2 . It may be in the form of a helical spring that performs.

Receiving area 3 has an opening in the form of a slot which serves as a passage for the tabs 41 to 43 ; 51 , 52 ; 61 to 63 ; 71 , 72 to be drawn into the interior of the filling system 1 , these slots ( 8) is referred to in FIGS. 3 and 4 .

Tabs 41 to 43; 51, 52; 61 to 63; 71, 72 may be arranged concentrically with respect to a circular portable electronic element, but are not limited thereto. Since electronic devices are generally rectangular in shape, such an arrangement can be made in successive rectangular regions surrounding each other.

The smallest rectangular area corresponding to the smallest portable electronic device 2 of the selected one of the portable devices is delimited at least discontinuously by the innermost series of tabs in the stand. This rectangular area is surrounded at a distance by one or more rectangular areas corresponding to an increasingly large portable electronic device. This or these rectangular areas are delimited at least discontinuously by one or more series of tabs progressively proximal to the outer contour of the stand.

Thus, each series of tabs may form a rectangular area between the tabs 41 - 43 ; 51 , 52 ; 61 - 63 ; 71 , 72 . The tabs 41 to 43 ; 51 , 52 ; 61 to 63 ; 71 , 72 on the longitudinal or lateral side of the rectangular region thus formed are opposite to the longitudinal or lateral central axis of the receiving surface 3 , respectively. It may be symmetrical with the tabs 41 to 43 , 51 , 52 ; 61 to 63 ; 71 , 72 on the longitudinal side or the lateral side.

Each tab 41 to 43 ; 51 , 52 ; 61 to 63 ; 71 , 72 of each series of tabs is a group of tabs located on the same side of the rectangular area closer or further away from the center of the receiving surface 3 . aligned with one or more respective tabs 41 to 43; 51, 52; 61 to 63; 71, 72 in one or more series.

For example, each longitudinal tab 51 or 52; 71 or 72 of each series of longitudinal tabs may be one or more of one or more series of tabs located on the same side of the rectangular region laterally of the rectangular region surrounding it. aligned with respective tabs 52 or 51 ; 72 or 71 . This also applies to longitudinally aligned lateral tabs 41 to 43; 61 to 63 of the rectangular region.

The tabs 43 ; 52 ; 63 ; 72 of the series of tabs may have a lower protrusion height than the tabs 41 , 42 ; 51 ; 61 , 62 ; 71 of the series of tabs that are more external to the rectangular area. . Thus, a continuous series of tabs can form a layer that increases in height relative to the receiving surface 3 formed by the filling system 1 towards the outside of the series. This is shown in FIGS. 1 and 2 .

The tabs 41 to 43 ; 51 , 52 shown in FIG. 1 may be of a smaller thickness and may for example be in the form of a blade or the tabs 61 to 63 ; 71 , 72 shown in FIG. 2 may be of a greater thickness. can be Accordingly, aligned tabs 41-43; 51, 52; 61-63; 71, 72 of an adjacent series of tabs have greater thickness tabs 41-43; 51, 52; 61-63; 71, 72. In the case of , they are immediately adjacent, or in the case of the tabs 41 to 43; 51 and 52 forming the blade, they are separated by a narrow spacing 9. The tabs may also advantageously be in the form of a pin with a rounded tip.

Tabs 41-43; 51, 52; 61-63; 71, 72 may be continuous over the entire width or length of the rectangular area, or tabs 41-43; 51, 52; 61-63 of the same series. 71, 72 may be discontinuous with an optional spacing 10, 11 between them.

For example, in FIG. 1 , the tabs 41 to 43 ; 51 and 52 are in the form of respective blades. On the two longitudinal sides of the defined rectangular areas two tabs 51 , 52 for two tab series are provided and these tabs are separated by a longitudinal spacing 11 .

In this same figure, the lateral sides of the defined rectangular areas are provided with three series of tabs each corresponding to each rectangular area, the tabs 41 to 43 being separated by a lateral spacing 10 on the left side of FIG. 1 . On the other hand, a continuous series of taps is continuous end-to-end on the right side of FIG. 1 .

On the leftmost lateral side of the defined rectangular regions, in all series, the tabs 41 to 43 of the same series are discontinuous, separated by a lateral spacing 10, which lateral spacing is on the longitudinal side of the rectangular region. It is not necessarily the same as the longitudinal spacing 11 . Advantageously, the lateral spacing 10 is smaller than the longitudinal spacing 11 . Tabs of the same series on the rightmost lateral side of the defined rectangular regions are continuous.

2 , the tabs 61 to 63 ; 71 , 72 have a wider support area. In this figure, a series of tabs 61 to 63 ; 71 , 72 on the same side in both the lateral and longitudinal directions of the rectangular regions form layers, which layers form the layers of the regions as shown on the right lateral side. It is either continuous in width, or discontinuous with lateral spacing 10 between tabs in the same series as shown on the left. These layers are discontinuous in the length of the rectangular regions on the longitudinal sides and are separated by a longitudinal spacing 11 .

In this FIG. 2 , the lateral sides of the rectangular areas are provided with three series of tabs, while the longitudinal sides of the rectangular areas are provided with two series of tabs. between aligned tabs 61-63; 71,72 forming identical layers in both the lateral and longitudinal directions; A separation distance sufficient to permit actuation of the tabs 61-63; 71, 72 without interfering with the aligned tabs 61-63; 71, 72 of an adjacent series is maintained.

1 and 2, a continuous arrangement is provided on the lateral side of the tabs 41 to 43; 51, 52; 61 to 63; 71, 72 of the same series and a discontinuous arrangement is provided on the other lateral side. is not essential. Conversely, arranging the tabs 41 to 43 ; 51 , 52 ; 61 to 63 ; 71 , 72 of the same series is advantageously continuous or discontinuous on both sides of the two and advantageously on all four sides of the rectangular regions. can be hostile
