Description

A kind of device for USB interface extension

Technical field

The utility model relates to a kind of device for USB interface extension, particularly a kind of for ultrathin electronics The USB 3.1Type-C interface of equipment, the docking station of built-in power supply.

Background technology

At present, (as known to the skilled person, USB 3.1 specification is special by English to USB 3.1Type-C standard criterion The USB industry standard that the companies such as that initiate；And for example well known to a person skilled in the art, " Type-A ", " Type-C " I.e. USB 3.1 interface of type-A or C type, they are parts for USB 3.1 standard) announced, this can make future The electronic equipment interfaces unification of patchcord and such as notebook computer, panel computer, mobile phone etc and unification.USB 3.1Type-C interface has many advantages, such as: size little (horizontal 8.3mm, longitudinal 2.5mm), support positive and negative socket, data Transmission speed fast (up to 10-20GB/s), support electric power transmit PD agreement and can transmit video, audio frequency and data etc. simultaneously.

But, existing USB 3.1Type-C standard interface cannot be connected directly to USB Type-A interface equipment, such as There are the USB flash disk of USB Type-A interface, portable hard drive, mobile CD ROM, printer, smart mobile phone etc..Further, trendy ultra-thin Type notebook computer tends to configure USB interface less and less.Such as, 12 cun of notebook computers of the up-to-date issue of AppleOn in addition to earphone interface, only one of which USB 3.1Type-C interface simultaneously as power supply and data transmission With.While this simple Interface design is the advantage that notebook computer brings ultraportable design, also bring very for user Inconvenience on the most actually used.Such as, if user needs to use above-mentioned traditional USB Type-A interface equipment, or user needs External large-screen display, then being required for extra adapter could realize.

In order to solve above-mentioned problem, all multi-vendor including Apple gives some USB3.1Type-C collection The solution of line device class, it is intended that USB 3.1Type-C Interface Expanding becomes the USB Type-A of one or more standards connect Mouth and a video interface.But, these products pass as power supply and data while mostly occupying on notebook computer Defeated only one USB 3.1Type-C interface, such as, be used only as data transmission and use；Further, only on minority product with electricity The access function in source (that is, the male with a USB 3.1Type-C, the female of a USB 3.1Type-C, external in female The charger that notebook computer carries to supply for the work of notebook computer, the battery of notebook computer and miscellaneous equipment Electricity).

Additionally, above-mentioned solution is in addition to use mentioned above is loaded down with trivial details, inconvenient, also a potential problem is: The power supply usual power ratio that a lot of extra-thin notebook computers carry is relatively low, the most enough supply notebook computer itself.Example As,Self-powered power only has 29W, butWhen processing high load capacity task, instantaneous power consumption demand 27W can be reached；Therefore, ifCharger also simultaneously for miscellaneous equipment such as portable hard drive or smart mobile phone (such as the iPhone of Apple), in power supply, even if being the most at this moment connected to charger, due to the deficiency of power supply, also can need WantBattery carry out auxiliary power supply, the use that the most likely can bring external equipment is unstable, connect A series of potential problems such as the minimizing of disconnected and battery life.

Accordingly, it would be desirable to what a kind of power supply adaptor by notebook computer type and USB 3.1Type-C hub were integrated USB interface expanding unit.
