Abstract

The invention discloses a wireless charger, a mobile terminal and a wireless charging system. By arranging a first charging circuit and n transmitting coils (n≥2) in the housing of the wireless charger, the power input terminal of the first charging circuit is connected to the The external power supply is connected, and the power output terminal is connected to n transmitting coils; under the excitation of the output of the first charging circuit, the n transmitting coils transmit the charging power to the mobile terminal through m transmitting frequency bands (n≥m≥2). The k receiving coils of the mobile terminal receive the charging power (k≥1) transmitted by the wireless charger, and store the received charging power into the battery through the second charging circuit. In this way, the mobile terminal is simultaneously charged on at least two frequency bands, the charging efficiency of the wireless charger is improved, the user's demand for charging efficiency is met, and the user experience satisfaction is improved.

Description

technical field [0001] The present invention relates to the field of wireless charging, and more specifically, relates to a wireless charger, a mobile terminal and a wireless charging system. Background technique [0002] With the continuous development of electronic technology, different mobile terminals in the traditional charging method must rely on matching charging cables to be charged, which has been unable to meet people's charging needs. The wireless charging technology has gradually replaced the traditional charging technology because it has the characteristics of simple use, convenience, durability, etc., and can realize a wireless charger to charge different mobile terminals. However, when the existing wireless charger performs wireless charging, its charging efficiency is low, which cannot meet the user's demand for charging efficiency, and the user experience satisfaction is poor. Therefore, it is necessary to propose a new wireless charger to solve the above t...
