Optical charger with light receivers and light emitters

摘要

An optical charger includes a fixing block, a number of light receivers, a substrate, and a number of light emitters. The fixing block is used for receiving a battery. The light receivers are fixed on the fixing block. The battery is electrically connected to the light receivers. The substrate has a loading surface for loading the fixing block. The light emitters are positioned on the substrate and face the light receivers. The light emitters are electrically connected to an external power supply, and are used for converting electrical energy from the external power supply into optical energy and emitting light rays. The light receivers are used for receiving the light rays from the light emitters, and converting optical power of the light rays into electric energy. The battery receives and stores the electric energy.

主权项

1. An optical charger for charging a battery, comprising:
a fixing block for fixing the battery; a plurality of light receivers fixed on the fixing block and configured to convert optical power into electric power to charge the battery; a substrate comprising a loading surface for loading the fixing block; a plurality of light emitters positioned on the substrate, the light emitters facing the light receivers when the fixing block is positioned on the loading surface, the light emitters configured to obtain electrical energy from an external power supply and emit light rays to the light receivers; a pressure sensor configured for sensing whether the fixing block and the battery are positioned on the loading surface, wherein the pressure sensor is exposed from the loading surface, the pressure sensor comprises a sensing module, a storage module, and a comparison module, the sensing module is configured for sensing a press applied thereon to obtain a press value, the storage module stores a predetermined pressure value, the predetermined pressure value is substantially equal to a sum of a weight of the fixing block and a weight of the battery, the comparison module is configured for comparing the obtained pressure value to the predetermined pressure value, when the obtained pressure value is greater than or equal to the predetermined pressure value, the comparison module determines that both of the fixing block and the battery are loaded on the loading surface; and a controller electrically connected to the sensor and the light emitter and configured for controlling to power the light emitters on when the sensor senses that both of the fixing block and the battery are positioned on the loading surface.
