USB data wire integrated with same-screen function

Abstract

The invention relates to the technical field of an electronic product, and particularly to a USB data wire integrated with a same-screen function. The USB data wire comprises a data wire body, a firstUSB connector and a second USB connector which are respectively arranged at two ends of the data wire body. An integrated master control chip which is used for reading same-screen data that are transmitted through the first USB connector or the second USB connector and regulates a current signal between the first USB connector and the second USB connector is packaged in the first USB connector. At least one HDMI interface which is connected with the integrated master control chip for outputting the same-screen data to outside is embedded into the first USB connector. According to the USB datawire, the traditional USB data wire is used as a carrier; a physical structure space which is supplied by the USB connector is utilized for assembling the HDMI interface and the USB connector in a hidden manner; through matching of the integrated master control chip in the USB connector, the whole data wire has functions of same-screen transmission and quick charging. The USB data wire prevents problems such as insufficient electric energy in same-screen of client terminals such as mobile phone, and effectively improves a same-screen experience effect.

Description

technical field [0001] The invention relates to the technical field of electronic products, in particular to a USB data cable integrating the functions of the same screen. Background technique [0002] As we all know, screen adapters and USB data cables are two of the most common accessories for electronic products in people's daily life and work; among them, screen adapters are mainly used to connect mobile phones, tablet computers and other electronic products with large-screen display devices (such as TV, projector, etc.) to connect the small screen to a large screen in real time with the same screen display function, while the USB data cable is mainly used to realize the data transmission or charging function between the computer or power supply and such as mobile phone and tablet computer .

Problems solved by technology

[0003] At present, most of the wired screen sharers on the market do not have the functions of USB data transmission and charging. Taking the screen sharing of mobile phones as an example, the direct impact is: when the mobile phone and the large-screen display device share image data on the same screen , the power of the mobile phone has been in a state of gradual consumption. Once the power of the mobile phone is exhausted, it is necessary to disconnect the screen adapter and use the USB data cable to charge the mobile phone. This will not only greatly affect the experience of the same screen, but also Moreover, it virtually increases the cost for users to purchase the same screen device and USB data cable

At the same time, due to the influence of factors such as small size, compact structure, and unreasonable structural design, the existing wired screen sharers (especially mini screen sharers) generally have problems such as unsatisfactory heat dissipation and short service life.
