Abstract

The invention relates to the technical field of wireless charging, in particular to a wireless charging transmitting device and receiving device and a wireless charging system. The wireless charging system comprises the wireless charging transmitting device and the wireless charging receiving device, wherein the wireless charging transmitting device comprises a first shell, a transmitting coil assembled on the inner surface of the first shell and a first magnetism isolating sheet arranged above the transmitting coil, and the first shell is made from an injection molding ferrite material or a first injection molding ferrite component is embedded in the first shell; the wireless charging receiving device comprises a second shell, a receiving coil assembled on the inner surface of the second shell and a second magnetism isolating sheet arranged above the receiving coil, and the second shell is prepared from the injection molding ferrite material or a second injection molding ferrite component is embedded in the second shell. According to the wireless charging system disclosed by the invention, the charging efficiency can be effectively improved, and simultaneously, the structural strength and attractive appearance of the product can be guaranteed under the condition that the shell thickness of the product is unchanged.

Description

technical field [0001] The present invention relates to the technical field of wireless charging, in particular to a wireless charging transmitting device, a receiving device and a wireless charging system. Background technique [0002] Wireless charging technology mainly uses the principle of electromagnetic induction or magnetic resonance for energy transmission. Due to the structural strength requirements of wireless charging products, a protective shell with a certain thickness will be provided between the coil of the wireless charging transmitting device and the coil of the receiving device, which makes the distance between the two coils relatively large, and there is a problem of magnetic flux leakage, and Large magnetic resistance leads to large magnetic loss and reduces the efficiency of wireless charging. Contents of the invention [0003] The purpose of the present invention is to provide a wireless charging transmitting device, a receiving device and a wireless...
