Embodiment Construction

[0019] Such as figure 1 As shown, the mobile phone wireless charging device is powered by the power supply 1, and the power management circuit 2 is a Boost-Buck circuit, which converts the power supply into 5V-20V direct current. This voltage can be adjusted by the communication and control circuit 3 according to the signals fed back from the wireless receiving circuit 6 and the coil sampling circuit 5; the DC power source converted by the power management circuit 2 supplies power to the high frequency oscillation and power amplifier circuit 4; The management circuit 2 can adjust the voltage, so the output power of the wireless transmitting coil 8 can be controlled by adjusting the output voltage of the power management circuit 2. The tuning capacitor 7 is used for frequency matching of the oscillation circuit.

[0020] The communication and control circuit 3 can generate a high-frequency square wave signal with a frequency range of 100KHz to 250KHz, and the signal is amplified b...

Abstract

The invention discloses a mobile phone case for mobile phone wireless charging. The mobile phone case for the mobile phone wireless charging comprises an embedded wireless receiving antenna, a rectifying module and a charging interface. The wireless receiving antenna receives energy from a wireless charging transmitter, the energy is converted into direct current voltages suitable for mobile phone charging through the rectifying module which is integrated on the case, and then a mobile phone is recharged through the charging interface. A wireless charging function can be provided for an existing mobile phone which is not provided with the wireless charging module, and the existing functions of the mobile phone are not affected.

Description

Technical field [0001] The present invention relates to mobile phone wireless charging, in particular to a mobile phone shell used for mobile phone wireless charging. Background technique [0002] At present, mobile phones are charged in a wired connection mode, which has problems of inconvenience and waste of resources. [0003] There are a small number of wireless charging and transmitting systems, but because most mobile phones are not equipped with a wireless receiving module, it is impossible to achieve wireless charging for existing mobile phones. Summary of the invention [0004] The technical solution of the invention consists of a shell embedded with a wireless receiving antenna, a rectifier module and a charging interface. [0005] The wireless receiving antenna receives the energy from the wireless charging transmitter and converts it into a DC voltage suitable for mobile phone charging through the rectifier module integrated on the housing, and then charges the mobile pho...
