Abstract: A wireless charging module can include a base, a charging coil module, and a switch. The charging coil module can be releasably securable to the base. The charging coil module can include one or more electrical connectors to electrically engage with the base when the charging coil module is secured to the base. The charging coil module can be interchangeable between a single coil module and a multi-coil module. The wireless charging module can be configured to wirelessly charge a mobile device when the charging coil module is secured to the base. The switch can be movable between a first configuration and a second configuration. The switch can be configured to secure the charging coil module to the base in the first configuration and the switch can be configured to release the charging coil module from the base in the second configuration.

Abstract: A wireless charging module includes a magnetic alignment component located higher in the Z axis than the transmitting coil, thereby enabling the magnetic alignment component to be closer to a mobile device positioned on a charging surface of the wireless charging module, which can provide better alignment between the transmitting coil of the wireless charging module and the receiving coil of the mobile device. In exemplary embodiments, the magnetic alignment component comprises a magnetic ring in a projection of a housing of the wireless charging module or embedded within a compliant/flexible cover configured to extend along a top portion of the wireless charging module. This can help ensure the magnet alignment components of the wireless charging module and the mobile device are close enough together to produce a sufficient magnetic force to pull the mobile device into proper alignment and provide superior alignment between the coils of the two devices.
