Abstract

The invention discloses a charging structure of a mobile terminal and the mobile terminal. The charging structure comprises a main board, a small board and a battery, wherein the battery is arranged between the main board and the small board; the small board is used for connecting a battery charging socket, the battery comprises two battery connectors, one battery connector is buckled with the main board, and the other battery connector is buckled with the small board; and a direct charged MOS (Metal Oxide Semiconductor) transistor is arranged on the small board, the battery charging socket is connected with one end of the MOS transistor via the small board, and the other end of the MOS transistor is connected with the battery connector via the small board. By adopting the charging structure, the charging efficiency of the terminal is higher, and the problem of high local heat is solved.

Description

technical field [0001] The invention relates to the technical field of mobile terminals, in particular to a mobile terminal charging structure and a mobile terminal. Background technique [0002] Fast charging is becoming a trend in mobile phone design. The low-voltage and high-current direct charging solution is gradually becoming a mainstream method of fast charging due to the advantages of high current and low heat generation. TI, Fairchild, Qualcomm, MTK, NXP, O2, etc. are launching low-voltage direct charging methods. [0003] The low-voltage high-current direct charging scheme is to charge the battery directly through the MOS tube after the charger is stepped down, and the current in the charging path is consistent with the current charged into the battery. The impedance loss on the path has a great influence on charging efficiency and heat generation. [0004] In the mobile phone design of the half-board solution, in the traditional single-interface battery solution...
