The present invention relates to a powering device and, more particularly, to a wireless powering device.
The emergence of wireless power supply technology has brought great convenience to the power supply of moving parts in electrical apparatuses. The wireless power supply technology may completely avoid many problems caused by physical wear, for example, along with problems related to safety, service life, and maintenance of the electrical apparatus. Moreover, the wireless power supply technology may greatly enhance the degree of freedom in the structural design of the electrical apparatus, and increase the aesthetic and functional features of the electrical apparatus, especially consumer electrical equipment, such as household appliances.
A wireless power supply device comprises a transmitting module and a receiving module, and the transmitting module must correspond to the receiving module one to one. At present, the most common wireless power supply technology is based on electromagnetic coupling. Generally, the wireless power supply device based on the electromagnetic coupling comprises a transmitting coil and a receiving coil. The transmitting coil must correspond to the receiving coil one to one. When the transmitting coil and the receiving coil are moved to close to each other, they are electromagnetically coupled to each other.
However, in practical applications, there is often a situation in which a load may be placed at any one of a plurality of different locations of the electrical apparatus. For example, in a refrigerator, a carrier may be placed at any suitable location of the plurality of different locations according to a height of an object to be loaded on the carrier. In order to supply power to a load (for example, a lamp, or a fan) mounted on the carrier, a transmitting module must be provided at each of the plurality of different locations. In this way, all transmitting modules may work at any time, leading to energy waste.
A wireless powering device includes a plurality of transmitting coils and a single transmitting circuit board to which the transmitting coils are electrically connected in series.
The invention will now be described by way of example with reference to the accompanying Figures, of which:
Exemplary embodiments of the present disclosure will be described hereinafter in detail with reference to the attached drawings, wherein like reference numerals refer to like elements. The present disclosure may, however, be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein; rather, these embodiments are provided so that the present disclosure will convey the concept of the disclosure to those skilled in the art.
In the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the disclosed embodiments. It will be apparent, however, that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and devices are schematically shown in order to simplify the drawing.
An electrical apparatus according to an embodiment is shown in
As shown in
A wireless powering device according to an embodiment, as shown in
After the carrier 11 loaded with the receiving coil 210 is mounted at one location of the plurality of different locations A1, A2, A3 of the electrical apparatus, the receiving coil 210 mounted on the carrier 11 is electromagnetically coupled with the transmitting coil 110 mounted at the one location to supply power for the load mounted on the carrier 11.
In the embodiment shown in
The plurality of transmitting coils 110, as shown in
In an embodiment, the receiving coil 210 is movably mounted on the electrical apparatus, so that the receiving coil 210 is movable within a coverage of an electromagnetic field of the plurality of transmitting coils 110.
A wireless powering device according to another embodiment, as shown in
After the carrier 11 loaded with the receiving coil 210 is mounted at one location of the plurality of different locations A1, A2, A3 of the electrical apparatus, the receiving coil 210 mounted on the carrier 11 is electromagnetically coupled with the transmitting coil 110 mounted at the one location to supply power for the load mounted on the carrier 11.
In the embodiment shown in
As shown in
The receiving coil 210 is movably mounted on the electrical apparatus, so that the receiving coil 210 is movable within a coverage of an electromagnetic field of the plurality of transmitting coils 110.
A wireless powering device according to another embodiment, as shown in
After the carrier 11 loaded with the receiving coil 210 is mounted at one location of the plurality of different locations A1, A2, A3 of the electrical apparatus, the receiving coil 210 mounted on the carrier 11 is electromagnetically coupled with the transmitting coil 110 mounted at the one location to supply power for the load mounted on the carrier 11.
In the embodiment shown in
As shown in
The receiving coil 210 is movably mounted on the electrical apparatus, so that the receiving coil 210 is movable within a coverage of an electromagnetic field of the plurality of transmitting coils 110.
The electrical apparatus shown in
In the above exemplary embodiments, the transmitting coil 110 may be mounted at each of the plurality of different locations A1, A2, A3 of the electrical apparatus. Therefore, when the carrier 11 loaded with the receiving coil 210 and the load is placed at one location of the plurality of different locations A1, A2, A3, the receiving coil 210 and the transmitting coil 110 at the one location will be electromagnetically coupled with each other. Therefore, in the present disclosure, it is unnecessary to check the location of the receiving coil 210 and the load. In addition, it is unnecessary to provide a plurality of independent circuit boards for the plurality of transmitting coils 110, which greatly improves the hardware utilization, simplifies the complexity of the wireless powering device, and reduces the cost.
It should be appreciated for those skilled in this art that the above embodiments are intended to be illustrative, and not restrictive. For example, many modifications may be made to the above embodiments by those skilled in this art, and various features described in different embodiments may be freely combined with each other without conflicting in configuration or principle.
Although several exemplary embodiments have been shown and described, it would be appreciated by those skilled in the art that various changes or modifications may be made in these embodiments without departing from the principles and spirit of the disclosure, the scope of which is defined in the claims and their equivalents.
