Description
Technical field
The utility model relates to a kind of USB expanded structure of tool charge function, a kind of electrical installation electric energy supplement that provides is provided, possess the USB slot that the matchmaker connects main frame simultaneously, provide information to transmit, seek the USB expanded structure of functions such as footpath and transmission.
Background technology
Its English full name of USB is Universal Serial Bus, and Chinese is " USB ".USB is a kind of linkage interface of standard, when permission is connected the equipment of outside with main frame, needn't reconfigure planning system, also needn't open casing, adjusts the thumb-acting switch of interface card in addition.And connect when going up main frame, main frame can be discerned these interface equipments automatically, and joins attached suitable driver, need not the user and resets in addition.Below, list the many characteristics and the advantage of USB:
1. USB (universal serial bus) has been unified the connector of various interface equipment, comprises communication interface, printerfacing, display output, audio I/O device, storage facilities etc., all adopts identical USB (universal serial bus) specification.USB (universal serial bus) similarly is " cardan ", as long as plug is inserted, all just can be readily solved.
2. plug and play (Plug-and-Play), and the resource of energy Auto-Sensing and configuration-system.Moreover, need not be the demand of system resource.That is to say that universal serial bus device does not need to set in addition that IRQ interrupts, I/O address, and DMA's etc. is the system resource.
3. has " hot plug " (Hot Attach ﹠amp; Detach) universal serial bus device can be inserted or pull away to characteristic in the executing state of having started shooting of the operating system of main frame, at any time, and do not need powered-down in addition again.
4. USB can connect 127 interface equipments at most.Because USB (universal serial bus) is used the addressing field of 7-bit, so 27 powers equal 128.USB host is default to be used to the interface equipment that connects for the first time if deduct, and also surplus 127 addresses can be used.Therefore a main frame can connect 127 universal serial bus devices at most.
In brief, for the USB allomeric function is exactly to simplify online between external interface device and the main frame, and utilize and be connected in series all types of interface equipments on the transmission yarn (as the port arranged side by side of printer, the serial port of modulator-demodulator), solved a lot of cables in main frame back now disorderly around predicament.The benefit of its maximum is can be at the following installation hardware of the situation that does not need to start shooting again.
Yet, main frame is built the USB of putting its restricted number, especially the development of computer peripheral equipment is maked rapid progress, early stage main frame, when can not supporting various computer peripheral equipment already, its USB number pegs graft, build the problem of putting the USB deficiency in order to solve main frame, industry exploitation at present has the USB expander, general user is at a USB that needs only USB expander grafting main frame, just can utilize many groups plug socket on the USB expander to support the grafting of various computer peripheral equipments, make computer peripheral equipment be able to connect the USB slot of main frame, carry out online use with main frame by USB expander matchmaker.
Yet, present USB expander on the market, its box-like main body must occupy certain space, in serial bus applications technology ripe today, if can not have multiple use concurrently, real difficulty meets the demand that the microminiaturized and many merits of modern science and technology are integrated.
In addition, the Wireless electrical appliance device, especially the relevant electrical installation of the computer peripheral equipment of Ying Yonging, such as wireless mouse or Wireless Keyboard etc., compared to traditional wired electrical installation, owing to have easily and carry, and advantages such as the occasion that does not limit use and distance, therefore widely the user accepts, yet so its energy of Wireless electrical appliance device is wireless, mainly be to rely on its inside to be provided with rechargeable battery, can keep its running required electric power, yet the electric power of rechargeable battery sometimes and thoroughly, therefore, the present practice is to possess a cradle is arranged, and is used for replenishing the electric power of Wireless electrical appliance device.
Above-mentioned Wireless electrical appliance device must occupy certain usage space because cradle is bulky, and the user still must carry cradle when carrying the Wireless electrical appliance device, replenishes with the electric power of keeping the Wireless electrical appliance device, and is very inconvenient.
This case inventor is because the above-mentioned USB expander and the shortcoming of charging device when actual using of Wireless electrical appliance device, and accumulation individual is engaged on the related industry exploitation practice experience for many years, study intensively, develop a kind of USB expanded structure of tool charge function finally.
Summary of the invention
Main purpose of the present utility model provides a kind of USB expanded structure of tool charge function, decapacitation supply electrical installation is electric energy supplement at any time, also have the USB slot that the matchmaker connects main frame concurrently, reach and allow user's interface equipment carry out connecting function by expander body and main frame, and be easy to carry, the user is provided plug and play, expands the support computer peripheral equipment.
In order to achieve the above object, the utility model provides a kind of USB expanded structure of tool charge function, has the expander body, forms charging storing face in this expander body end face and forms.As above-mentioned structure, connect the USB slot of main frame with the transmission line matchmaker by this expander body, allow user's interface equipment by carrying out information interchange between expander body and main frame, and utilize the charging of this expander body end face to put face, make the electrical installation electric energy supplement that is positioned on this charging storing face.
