Abstract
The utility model discloses a U disk based on a universal serial bus on-the-go (USB+OTG) technology. The U disk comprises a shell and a memory, and is characterized by also comprising a USBOTG integrated control chip, a USBOTG interface and a transmission key, wherein the USBOTG interface, the transmission key and the memory are connected to the USBOTG integrated control chip; when data is required to be transmitted, a transmission switch is set to be a turned-on state; and when the data is not required to be transmitted, the transmission switch is set to be a turned-off state. Due to the USBOTG interface, data can be directly exchanged among a plurality of sets of equipment and is not required to be forwarded by a personal computer (PC); and the U disk is convenient to use.
Description
Technical field
The utility model relates to a kind of USB flash disk, is specifically related to a kind of USB flash disk based on the USB+OTG technology.
Background technology
USB is simple to operate, and plug and play is free disclosed standard.Existing many USB devices on the current market; USB can be described as ubiquitous present many portable terminals, as: mobile phone, PDA, MP3, portable set manufacturers such as digital camera; All USB interface is added on the product, but they also can only be as the exchanges data of PC peripheral apparatus and PC.Do not use PC; Directly more and more in the demand that equipment room connects. in asking during short several years, USB interface has become the interface the most widely of computer peripheral, movable storage device, digital product and even mobile communication equipment and computer interconnection, and the figure of USB interface is almost ubiquitous; Although USB2.0 can support up to the robust and sturdy defeated rate of the data of 480Mbps; Support the hot plug function, can connect 127 USB devices simultaneously at most, transmit advantages such as stable; But traditional USB standard that the most fatal is exactly is a cover universal interface standard of developing around PC, makes USB not support the point-to-point connection of non-PC.Can't direct communication between any two peripheral hardwares or between two main frames, and OTG equipment can serve as main equipment and can serve as slave unit, following two the OTG equipment of situation that can be implemented in no PC directly link to each other and realize point-to-point communication.It all is to be connected with computer that the traditional U dish imports outgoi8ng data into, does not have in some place under the situation of computer, can't data imported into or spreads out of USB flash disk.
The utility model content
To above-mentioned prior art, the purpose of the utility model is providing a kind of USB flash disk based on the USB+OTG technology.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of USB flash disk based on the USB+OTG technology comprises shell, storer, it is characterized in that, also comprises the integrated control chip of USBOTG, USBOTG interface and transmission button, and said USBOTG interface, the connection of transmission button and storer are to the integrated control chip of USBOTG; Transmitting switch is set on off state when needing the transmission data, on the contrary the closed condition of being set to.
Compared with prior art, the utlity model has following beneficial effect:
Because of the existence of USBOTG interface is arranged, can realize directly carrying out between the plurality of devices simultaneously exchanges data, need not transmit data by PC, use more convenient.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
To combine accompanying drawing and embodiment that the utility model is done further to describe below.
A kind of USB flash disk based on the USB+OTG technology comprises shell, storer, it is characterized in that, also comprises the integrated control chip of USBOTG, USBOTG interface and transmission button, and said USBOTG interface, the connection of transmission button and storer are to the integrated control chip of USBOTG.Because of the existence of USB OTG interface is arranged, can realize directly carrying out between the plurality of devices simultaneously exchanges data, need not transmit data by PC, use more convenient.A change-over switch is set, change-over switch is allocated to open mode when USB flash disk needs Bluetooth function, otherwise, change-over switch is allocated to closed condition.
