Abstract

The invention discloses a wireless charging device, a mobile terminal supporting wireless charging and a wireless charging system. The wireless charging device comprises a charging base, wherein a transmitting circuit, a transmitting coil, a movable daughter board for fixing the transmitting coil, and a positioning magnet are arranged in the charging base; the transmitting coil is connected to the transmitting circuit through a lead wire; and the positioning magnet is fixed on the daughter board in a mode of being positioned in the transmitting coil. When the wireless charging device and system disclosed by the invention are used for carrying out wireless charging on the mobile terminal, the mobile terminal is unnecessary to shift, is only arranged on the charging base of the wireless charging device and can be placed at will; and when wireless charging is not performed, the daughter board is fixed near the transmitting circuit and cannot be moved at will. According to the wireless charging device and system and the mobile terminal disclosed by the invention, the mobile terminal can be charged by the wireless charging device conveniently, and the experience effect of a user using wireless charging is also enhanced.

Description

technical field [0001] The invention relates to mobile terminal charging technology, in particular to a wireless charging device, a mobile terminal supporting wireless charging and a wireless charging system. Background technique [0002] At present, the functions supported by mobile terminals are becoming more and more powerful, and their applications are becoming more and more extensive. Mobile terminals can be used as entertainment tools for users, such as listening to songs, watching TV programs, and surfing the Internet through mobile terminals. During the use of the mobile terminal, due to the limitation of the battery capacity, the power will be used up soon, and the battery often needs to be charged. [0003] The emergence of wireless charging technology represented by electromagnetic induction has brought convenience to consumers. The wireless charging device can conveniently charge the mobile phone, freeing the user from the shackles of the charging cable. Howeve...
