Multifunctional accessory

Abstract

The invention discloses a multifunctional accessory and belongs to the technical field of an accessory of an intelligent terminal. The multifunctional accessory comprises a data line, a mobile terminal connector, a memory module (or a USB key), a bluetooth anti-lost module, an NFC module and the like, which are in multifunctional integrated application. The memory module (or the USB key), the mobile terminal connector and a USB connector are connected; whether the mobile terminal connector serves as a master device interface or a slave device interface can be determined by a path control switch, and thus switching between HUB or OTG two application models is realized; the multifunctional accessory not only can support a computer to carry out access, data read-write and charging on the internally-arranged memory module (or the USB key) and other electrical devices ( such as a mobile phone and a tablet PC and the like) connected via the mobile terminal connector, but also support the intelligent terminal to carry out access, data read-write and charging on the internally-arranged memory module (or the USB key) and other electrical devices ( such as a printer and the like) connected via the USB connector; and integrated with a plurality of functions, the multifunctional accessory is allowed to be more small and exquisite, convenient to carry and not easy to lose.

Description

technical field [0001] The invention belongs to the technical field of intelligent terminal accessories. Background technique [0002] Nowadays, whether it is a mobile storage device or an application of electronic identity authentication technology, it generally exists in the form of an independent individual. Today, as terminal devices are becoming more and more diverse, people often have two or more mobile terminals at the same time, and each terminal The data storage and transmission methods are different, which brings the following problems: [0003] 1. There are many types of external terminal accessories such as data cables, U disks, anti-lost devices, and electronic identity authentication. At the same time, they are poor in portability and are easily forgotten or lost by users; [0004] 2. A variety of mobile terminals may have different data and charging interfaces, often users need to wear more than two interface data lines or charging equipment, causing unnecess...

AI Technical Summary

Problems solved by technology

[0003] 1. There are many types of external terminal accessories such as data cables, U disks, anti-lost devices, and electronic identity authentication. At the same time, they are poor in portability and are easily forgotten or lost by users;

[0004] 2. A variety of mobile terminals may have different data and charging interfaces, often users need to wear more than two interface data lines or charging equipment, causing unnecessary troubles in users' lives;

[0005] 3. The data transmission between various terminal devices such as computers, mobile phones, and PADs lacks a medium suitable for multiple interfaces and multiple purposes, and fast data exchange cannot be realized between devices;

[0006] 4. There are many types of external terminal accessories such as data cables, U disks, anti-lost devices, and electronic identity authentication, but the number of USB sockets (computer or charging stand) used to connect data transmission and charging is often insufficient;

[0007] 5. The existing mobile payment is usually completed on a single smart device (mobile phone or PAD). The insecurity of the smart device system and the weak identification of users cause the unreliability of mobile payment, and the security of mobile banking and mobile payment is positive. By the majority of users' attention
