FIELD

The invention relates to a novel apparatus and method for contact-free manner for transmitting electrical energy.

Background technique

Many of today's portable devices can be recharged in conjunction with the "ancillary" battery, to save costs, and eliminates the inconvenience to regularly buy a new battery brings. Examples of these portable devices including cellular phones, laptop computers, handheld 500 series personal digital assistant, electric shavers and electric toothbrushes. In some such devices, the battery connection rechargeable by inductive coupling rather than a direct electrical connection. Examples of such packages tongue 4 Braim Oral B Plak Control of the electric toothbrush, the Panasonic digital cordless telephony sad husband solution and Panasonic KX-PH15AL men's razor bull ES70 / 40 series.

Each of these devices typically has an adapter or charger, the adapter or charger power supply qe human power, only a few car cigarette or other ignition power draw power, and converts it into a battery adapted to be charged form. There are many problems to provide power or charging equipment used for these conventional methods:

• characteristics of a battery in the apparatus and method of each connected to the battery depending on the manufacturer and equipment vary considerably. So users have several such devices must also have several different adapters. If you plan to travel and want to use their devices during this time, they will have to bring all their chargers.

• These adapters and chargers often requires the user to a small connector into the machine, or stand placed in precise alignment, which causes inconvenience. If the user fails to insert their device into the charger or into the device and have run out of power, the device will be rendered useless, and important data stored locally on the device may even be lost.

• In addition, most adapters and chargers have to be inserted into a power outlet, so if several adapters and chargers ^ f together with the officials, they will take up space strip, and clutter and confusion caused by wires intertwined.

• In addition to the above-described problems of the conventional method i Shu brought recharging apparatus, having an open electrical contact device there are many practical problems. For example, due to possible corrosion of the contacts or short ^ F ^ lai respective contacts, I Shu apparatus can not be used in humid environments, and since the spark may be generated, the device can not be used in flammable gaseous environments.

Using inductive charging charger need not have open electrical contacts, and so that the adapter device can be sealed and used in wet environments (e.g., a power toothbrush mentioned above is designed for bathroom). However, this charger is still facing all the other problems mentioned above. For example, the device is still necessary to accurately "Great placed in the charger, and the charging device 4 to give officials

The appliance is in a predetermined relative position (see FIGS. La and lb). J-defined product remains adapter is designed to be dedicated to a certain type and configuration of equipment, and still only be able to charge the device one at a time. As a result, users still need to own and manage a number of different adapters.

Also there universal charger (e.g. Maha MH-C777 + universal charger), so that the battery pack and the characteristics of different shapes can be removed from the device, and a device using the same charge. Although these universal charger eliminates the need to have different chargers for different devices, but they had to the user even greater inconvenience, because the battery needs to be removed first, and then need to be adjusted charger , and the battery pack needs to be placed accurately relative to the charger or the charger disposed. Further, the charger must spend time must be determined using a 4 officials battery correct set of metallic contacts.

The pair of coils are designed to operate in opposite phases, so that the "other coil hereby force from one coil to the line coupling. The electronic device may be such as a watch; set change in the two coils 4 wife received power.

From WO 00/61400 "for the inductive power transfer device (Device for Inductively Transmitting Electrical Power) ,, learned, which is for a 4 bar before transferring power inductively to the method of delivery device.

Qe al WO 95/11545 "eligible ear and inductive power coil (Inductive power pick-up coils)" learned, provides for an electric vehicle built from a series of flat primary coil 4 is inductively powered energy system.

To overcome the limitations of the system requires a secondary device and the primary inductive power transfer means axially aligned, some may raise an obvious solution, i.e. the use of a simple inductive power transfer system, the primary system by means of which the apparatus can National Chiao Tung University emission region within l "hereby field (see FIG. 2a). The user can put a single cylinder or a plurality of charging devices to be placed within range of the primary device, without requiring the precise placement thereof. For example, this means may comprise a primary coil encircling a large area. When the current flows through the coil, an electromagnetic field is generated in a large area extended range, the device may be placed at any position within the region. Although this method is theoretically feasible, but it has many drawbacks. First, electric "hereby emission intensity is controlled by the adjustment range. This means that the method ^ U righteous support a limited rate of energy transfer. Furthermore, many objects may be affected by the presence of a strong magnetic field. For example, data stored on a credit card may destroy the skin, and made of a metal object inside the induced eddy current is generated, resulting in undesirable heating effect. Another evening Bu,

If the coil comprises a conventional ii (see FIG. 2a) and a secondary device such as a copper plate or a metal case of the battery within the printed circuit board is placed opposite the coupling may be significantly reduced.

In order to avoid a large magnetic field, it may be an array of rings of wire been suggested, by means of which only the desired line coil array transdermal ^ rings of activation (see FIG. 3). The method in Japan, "the journal Society is hereby published November 29, 2001, entitled" Si no desktop constricted ring-shaped habit Dog (Coil Shape in Desk-type Contactless Power Station Syetem) 4 jump in shock station system " the paper described. In one embodiment of the multi coil principle, the sensing mechanism detects the secondary device relative position of the primary device. Then, the control system activates the appropriate manner to position the wire rings of the transmitted power to the secondary device. Solution to the problem before While this method provides a listed, l Dan is complex and expensive to implement. Degree can be positioned by the primary field coil limitation of quantity, and therefore limited number of drive circuits to be used (i.e., "primary device ,, decomposition). The cost of a multi-coil system would greatly limit the commercial applications of the principles of the the field is the uneven distribution of a defect. when all the coils within the primary means are activated, which together are equivalent to a large coil, its "field distribution in the center of the coil hereby display is minimized.

Another aspect to be outlined in US 5,519,262 "near-field power coupling system (Near Field Power Coupling System)" in which the primary device arrangement having a large number of the flat plate from an end to another end of a narrow induction coil (or alternatively; also 4 anti-capacitance), a large amount of relative shift of the 4 vertical manner into 4 vertical field driving the right foot, J kai moved in the sinusoidal motion seeking anti ^. The receiving device is arranged with two vertical field receiving apparatus, so that no matter where the plate receiving apparatus is located, it is always received from the at least one device for collecting the electric energy. Although the program can provide free movement to the device, but it has some disadvantages that it requires a complicated secondary device, having a fixed return and due to decomposition of the through ^ ^ hereby air through each path is cross coupling 4.

Existing four surgery solutions do not satisfactorily solve all the problems have been described. Can be obtained if a solution can be all of the following features to transfer electrical energy to the portable device, and can be implemented in a cost-effective, it would be desirable: * GM: primary single device, which may have different power requirements different secondary device to provide power, thereby eliminating a plurality of different adapters and chargers necessary

Sex;

• convenience: a single primary means, which allows the secondary device is placed within the effective proximity of any location, thereby eliminating the necessity of a secondary device inserted precisely relative to the adapter or charger or placed;

• multiple loads: a single primary device, it can simultaneously provide power to a plurality of different secondary devices having different power requirements.

• flexibility for different environments: a single primary device, it is possible for a secondary power unit, without requiring a direct electrical contact jump to 4, person qe allow the secondary device and the primary unit itself may be used wet, containing gas, cleaning, and other abnormal environment;

• Low electromagnetic emissions: a single primary means to reduce the size and strength of the magnetic field which can be generated by energy transfer to the lowest way.

Further appreciated, a large number of portable devices are produced, they require battery power is able to punch them. Primary battery or a battery pack to be exhausted into the process right foot 4, which is both expensive and pollute the environment. The battery or batteries and may be Si and repeatedly charged into the right foot 4 <official use.

Many portable devices having means to meet industry standards, such as size and voltage of the AA, AAA, C, D, and PP3 battery container. This enables the user to freely choose whether to 4 with a primary battery or secondary battery officials and different types of batteries. Once exhausted, the battery must generally be removed from the device and placed into a separate charging device. Alternatively, some portable device has a built-in charging each ^ allow in situ charging the battery when the device is inserted into the external power source. For users, it is necessary to remove the battery from the device or to charge the device inserted into the external power source is charged in situ, this is inconvenient. Preferably non-contact manner by some charge the battery, without having to perform any such operation.

Some portable device can receive power from the charger by way of inductive coupling, for example

As the Plak Control Braim Oral B toothbrush. This "i Shu more portable apparatus generally has a custom, built in the power receiving device-specific module, and the module was shown with an internal battery or battery pack is connected to registration (the cell but may or may not at the ear and ).

However, if the user can simply by installing inductive charging the battery or batteries and it bar any accepted industry standard battery size <more portable i Shu apparatus converted to inductive charging apparatus, it will be very convenient, and wherein, by 4 to 7 bar device is placed in the inductive charging electric inductive charger; also electrically or> Si and the intake 4 is also in charge.

Examples of prior art further includes US 6,208,115, which discloses an electrical ^^ 4 Ge 〖a way inductive charging, and also Si.

• Optional "is hereby force lines aggregating devices

• power receiving means

, Converts the received power to a battery means adapted to transmit to the outside through the external form of the electrical connection means, means or device for charging the energy storage device, or both of the two functions. The proposed invention differs greatly from the traditional design of the inductive power transfer system. The difference between the conventional system and the proposed system can see their respective magnetic field lines in FIG.

Shaped best be elucidated. (See FIGS. 2a and FIG. 4)

• traditional systems: In the conventional system (see FIG. 2A), usually a planar primary coil which generates a "hereby field, the" are hereby field "hereby lines of force in a perpendicular manner out of the plane of the coil . Secondary device usually has about some or all of these "lines of force hereby round or square coil.

• The proposed system: in the punch is out of the system, "hereby field substantially horizontal surface along the forward loop plane (see FIG. 4), rather than directly from the plane of the coil shown in Figure 2a. Thus, the secondary device may have a core of about ten thousand hereby extended into the winding 4 wound right foot. See Figures 7a and 7b. When the secondary device "message is placed on the primary device, Wan hereby will be attracted across the line of force of the secondary magnetic core means advancement, since it is the smallest reluctance path. This means that the primary and the secondary device is efficiently coupled. Secondary device "hereby core and windings may be substantially flattened form a very thin member.

In describing the present invention, and as clearly visible, specific terminology will be used. However, this does not mean that the present invention be limited to the specific terms selected, it should be understood that each specific term includes all 4 in a similar manner into the Si Qiao for a similar purpose to achieve a synonym for surgery.

It should be understood that the terminology used in the present patent application "charge area" may mean at least a device (e.g., one or more wires present in the form of a coil) for generating a field region or regions formed by the primary conductor of the joint, in region, the secondary device can be effectively coupled "hereby lines of force. Some embodiments of the charging region in FIG. 6a-61 and 9c member 740 as shown. "I charging zone or" Laid ^ is a conductor pattern on the active area of ​​the primary device, and is configured so that at least one means for generating the field is possible - leather obtained instantaneously drive the flow in one direction is hereby net Wan lines of force. Primary charging device may have more than one region. When the lines of magnetic force can not (such as those shown in FIG. 7a) is valid secondary coupling means at any rotation at the boundary, a charging zone

Domain is different from another charging region.

It should be understood that the present patent 4 officials, the term "coil means all as described above ,, the

Charging conductor region structural features. This comprises a planar winding wire shown or printed traces or FIG. 8e. The wire may be made of copper, gold, alloy, or any other suitable material.

This application is referred to the "go turn of the secondary device in several places. It should be stated here that, if the secondary device is rotated, and a plane perpendicular to the rotational axis of the charging area is mentioned.

Overcome this fundamental change in the design of the traditional system of at least one defect. Benefits of the proposed invention tongue package 4:

• No correct alignment of Green 4: secondary device can; it is placed on the charging device of any region of the primary position;

Coupled uniformity: In the proposed invention, l Yu means between the primary and secondary engagement means compared with a conventional primary and secondary coils in the charging region i or more opening force uniform. In conventional large coil system (see FIG. 2a), the field strength in the central plane of the coil to minimize coil (see FIG. 2b). This means that if sufficient energy can be effectively transferred in a central position, then the minimum field strength must be above a certain threshold value. Then the maximum field strength is much higher than the required threshold, which could lead to undesirable results.

• GM: a plurality of different secondary devices, even those devices with different power requirements, can be placed on the charging surface of the primary charging device regions simultaneously receive power. • coupling coefficient to improve: the optional high permeability "within the secondary material by means hereby

Providing a low reluctance path greatly increases the magnetic flux generated by the induction. This can greatly increase the power transfer.

• means adapted over the secondary shape factor: the geometry of the system allows the use of a sheet material (such as an amorphous metal strip). This means that the form factor of the secondary device may have a sheet-like, such that it is adapted to be mounted at the rear of the mobile phone and other electronic devices. If the central hereby f 4 officials with conventional coil material, it is possible to increase the volume of the secondary device.

• Minimum field leak: when one or more secondary devices present in the region of the primary charging means, it is possible to use a magnetic material in this manner, even when more than half of the available "low hereby path; hereby barrier material (see FIG. 4d). This means that for a particular; 4 boast hereby motive force (magneto-motive force, mmf) hereby no more risk into the line of force 5. Since the rate of change of the induced voltage is proportional to the magnetic flux coupled, which will allow transfer of power to the secondary device is increased. The smaller the air gap and in each ^^ shorter fewer fringe field, the magnetic lines of force nearer the surface of the primary device, the leakage is minimal.

• cost-effective: the multi-coil ^: different terms, the inventive solution requires more

Simple control system and fewer components.

• free rotation about the axis of the secondary device: If the secondary device is a sheet-shaped or alternatively even be cylindrical (see FIG. 10) may be configured so that it remains a good coupling with the magnetic field lines, regardless whether rotate around the longest axis. If a secondary device is another battery cell i Shu in the mounting apparatus, when the rotation about the axis of the secondary device may be difficult to control, which may be a particular advantage.
