System and bracket for wireless charging device

The present invention relates to a stand for housing a device for wireless charging.

The wireless power transmission system transmits power from a power source to a power consuming device, and neither uses a solid line or a conductor. Wireless transmission includes the ability to provide electrical device power by using a plurality of different power transfer techniques of the electromagnetic field. In wireless power transmission, a transmitter device coupled to a power source typically transmits power through an electromagnetic field across an intervention space to a receiver device where it is then converted back to power and utilized. For an example, an effective charging area or wireless range for providing power to the receiver device may be limited to the size of the transmitter device itself. Therefore, the ability to wirelessly transmit power to a plurality of receiver devices may be limited.

In accordance with an embodiment of the present invention, a system is specifically provided comprising: a transmitter for wirelessly charging a device via a configuration bit within a receiver within each of the devices; and a bracket for receiving the transmission One of the devices in the wireless range, the bracket includes: a raised platform for supporting a plurality of devices; and an area below the elevated platform for containing the wireless range of the transmitter A number of additional devices.

The examples disclosed herein provide a solution for wirelessly transmitting power to a plurality of receiver devices within a range of effective charging regions of a transmitter device. In one example, in addition to a two-dimensional region of the active charging region, the solution described herein also allows the receiver device to wirelessly receive power from the transmitter device in a three-dimensional region. As with some wireless charging protocols that extend the active charging area beyond that area directly above the two-dimensional area of the transmitter device, a plurality of receiver devices can simultaneously receive power wirelessly from the transmitter device, for example, tolerating Has the ability to charge all receiver devices simultaneously.

Referring to the drawings, FIG. 1 illustrates a system 100 that includes a cradle 104 for accommodating a wireless range of one of the transmitters 102 or a plurality of receiver devices within an active charging area, according to an example. As shown, the transmitter 102 can be disposed within a base pad 101. However, the configuration of the transmitter 102 relative to the system 100 can be varied as will be further explained below.

In one example, the bracket 104 includes a raised platform 106 to support a plurality of receiver devices. Similarly, an area 108 located below the elevated platform 106 can accommodate a plurality of additional receiver devices within the wireless range of the transmitter. As with some wireless charging protocols, the active charging area may extend beyond the two-dimensional area of the transmitter 102, except for the receivers located within the area 108 below the elevated platform 106. The raised platform 106 of the bracket 104 can allow devices configured to be positioned on the elevated platform 106 to wirelessly receive power via the transmitter 102. In one example, the wireless charging protocol of the transmitter 102 can extend the Z range of the active charging region above the emitter 102 from 4-5 mm to about 50 mm. Thus, the height of the raised platform 106 can be within the Z range in which it extends. In one example, the transmitter 102 is adjustable to extend or reduce the wireless range of the transmitter 102.

2A-B illustrate an exemplary view of receiver device 110 housed within the effective charging region of the transmitter 102 by the cradle 104. As illustrated, a larger receiver device 110 supported by the raised platform 106 can lift a few centimeters in the Z direction above the surface of the base pad 101 while remaining in the emitter 102. Wireless range. In addition, the cradle 104 allows for smaller devices, such as tablets and mobile phones, to slide beneath the cradle 104 and also be within the effective charging area or wireless range of the transmitter 102. Although FIG. 2A illustrates a larger receiver device 110 supported by the raised platform 106 and a smaller receiver device 110 in the region 108 below the raised platform 106, the arrangement of the devices 110 may be illustrated The shower changes.

To wirelessly charge the receiver devices 110 for the transmitter 102, each device 110 can include a receiver (not shown) disposed within each device 110 to convert the electromagnetic field back from the transmitter 102. To power and utilized by each receiver device 110 (eg, for charging). When the receiver disposed within each device 110 is to be wirelessly provided within the active charging area of the transmitter 102, the bracket 104 considers that the receivers of each device 110 are located Within the effective charging area.

Referring to Figures 1 and 2A-B, the bracket 104 can be disposed above the transmitter 102. Thus, any receiver device 110 that is hosted by the cradle 104 above the transmitter 102 can be wirelessly powered by the transmitter 102. However, as an example, in addition to wirelessly providing receiver device 110 power that is configured above the transmitter 102, the transmitter 102 can also have a receiver device 110 that wirelessly provides configuration bits below the transmitter 102. The ability of electricity, as will be further explained.

3A-B illustrate a stand 300 that, according to an example, houses a plurality of receiver devices 110 positioned above a wireless range of the transmitter 302 or above and below the active charging area. The transmitter 302 can have a pair of regions 308 disposed below the raised platform 304 and a region 310 above the raised platform 304 by disposing the transmitter 302 in a raised platform 304 of the bracket 300. Receiver device 110, and the ability to wirelessly provide power by another receiver device 110 supported by an additional layer 306 above the elevated platform 304, as shown in Figure 3B. This additional layer 306 of the bracket 300 can accommodate additional receiver devices 110 to be powered by the transmitter 302 as compared to the bracket 104 of Figures 2A-B. This is possible when the transmitter 302 can have the ability to wirelessly provide power to configure the receiver device 110 above and below the transmitter 302. As mentioned above, the transmitter 302 can also be adjustable to extend or reduce the wireless range of the transmitter 302. For an example, the wireless range of the transmitter 302 can determine the size of the region 308 and the region 310.
