Expanding device for smart mobile phone

Abstract

The invention relates to an expanding device for a smart mobile phone, which comprises an interface module used for carrying out data interaction with a smart mobile phone, a data interface processing unit connected with the interface module and an I / O interface unit, wherein a processing unit of the interface module is also connected with the I / O interface unit through an I / O interface data lead wire; and the I / O interface unit is connected with an input and output device or an interface. The invention adopts a design that the smart mobile phone and the expanding device are separated, and the smart mobile phone is used as a main control module so as to ensure that the smart mobile phone can play roles of computer and communication more conveniently. In addition, the smart mobile phone is connected to various I / O devices and expanded functional units on the expanding device through a brand new designed magnetic interface on the expanding device and controlled and managed by a manager in the smart mobile phone. The performance and the functions of the smart mobile phone can be improved under the condition of not changing the smart mobile phone by increasing and deleting the I / O devices and the expanded functional modules.

Description

technical field [0001] The present invention relates to a smart phone expansion device that uses the expansion device to expand the hardware performance and interface of the smart phone.
