Abstract
A wireless charger inductively charges devices of various shapes and/or types, such as with multiple bend radii. Smartphones, headphones, key fobs, and other wireless devices may be laid atop the wireless charger. The wireless charger has flexible and pliable features that conform to the shape of the wireless device. The flexible and pliable features maintain a conformal relationship with the wireless device laid atop the wireless charger. The flexible and pliable features increase the efficiency of inductive power transfer and can reduce charge times and/or reduce heat generated due to thermal losses.
Claims20
A wireless charging pad assembly comprising:
- a top portion that forms a conformable non-slip cover that conforms to a shape of a device placed on the wireless charging pad assembly;
- a circuit including a charging coil mounted into a semi-rigid substrate, the semi-rigid substrate to keep the charging coil flat if the device placed on the wireless charging pad assembly is flat, and if the device includes a curved portion, the semi-rigid substrate bends to match an arc of the curved portion of the device that is proximate to the conformable non-slip cover;
- and
- a bottom portion to support the circuit disposed between the bottom portion and the top portion, the bottom portion being a rigid base to provide support to the conformable non-slip cover and the circuit, wherein the rigid base has a geometry that allows the conformable non-slip cover and the circuit to bend according to a weight of the device.
An information handling system inductively charging a device, comprising:
- a chassis;
- a motherboard mounted to the chassis;
- an outer enclosure housing the motherboard and the chassis;
- and
- a wireless charging pad assembly integrated with the chassis, wherein the wireless charging pad assembly includes:
- a flexible inductive charging coil mounted to a pliable semi-rigid substrate bending to a weight and shape of the device laid atop the wireless charging pad assembly;
- a bendable electrical circuit providing electrical power to the flexible inductive charging coil;
- and
- a bottom portion supporting the flexible inductive charging coil and the bendable electrical circuit, the bottom portion having a geometry allowing the flexible inductive charging coil and the bendable electrical circuit bending according to the weight and the shape of the device laid atop the wireless charging pad assembly.
An information handling system, comprising:
- a chassis;
- a motherboard mounted to the chassis;
- an outer enclosure housing the motherboard and the chassis;
- a hinge having a first leaf and a second leaf, the first leaf attached to the outer enclosure housing the motherboard and the chassis;
- and
- a wireless charging pad assembly attached to the second leaf of the hinge, the wireless charging pad assembly including a flexible inductive charging coil and a bendable electrical circuit, the flexible inductive charging coil mounted to a pliable semi-rigid substrate bending to a weight and shape of a device laid atop the wireless charging pad assembly, and the bendable electrical circuit providing electrical power to the flexible inductive charging coil to inductively charge the device, and wherein the wireless charging pad assembly has a deployed position and a stowage position, the deployed position outwardly extending via the hinge from the outer enclosure and conveying the electrical power to the flexible inductive charging coil, and the stowage position stowing via the hinge within the outer enclosure and disconnecting the electrical power from the flexible inductive charging coil.
