Description

Dual-port data storage device

Technical field

The relevant a kind of dual-port data storage device of the present invention refers to a kind of data memory device that is used in host computer, has two scalable interfaces especially.

Background technology

In recent years, the data fatching apparatus on the host apparatus (as PC) was along with science and technology was maked rapid progress and alarming development was arranged.Numerous computer peripheral devices mainly are coupled to computer system by USB interface, IEEE1394 interface or other interfaces and transmit data.Above-mentioned interface has the high-speed transfer sequence port usually, for the digital data transmission of computer and consumption electronic products is brought revolutionary development.The driver of suitable this peripheral equipment can be searched and download to the characteristic of its plug and play (comprising flash disc and the carry-on dish that is commonly called as " thumb ").These common interfaces have excellent data portability and maneuverability, but also are subjected to the influence of moisture or static and cause damage.Therefore, general flash disc or Pocket pen dish have cap usually and protect its transmission interface to avoid causing damage because of exposure.

Fig. 1 is the synoptic diagram of traditional Pocket pen dish, comprises cap 11, usb 12 and shell 13.Cap 11 is sleeved on shell 13 and covers usb 12 in order to cover.Have circuit in the shell 13 and store, transmit computer data, and electrically connect with usb 12.When the user when shell 13 takes off cap 11 and exposes usb 12, just can directly be plugged on the usb connecting port of computer, as the circumscribed hard disk drive, transmit or storage data.Therefore usb 12 one are connected in an end of shell 13, so for preventing that usb 12 from can be collided impaired, distortion, distortion even can't use, and just must be protected by cap 11.But in a single day cap 11 takes off, and just separates with shell 13 fully, and therefore the situation of losing cap 11 is often arranged, and the USB interface that often causes these existing portable storage devices is impaired and can't use.Therefore, it is important that the effect of protection USB interface also shows, so there is the gain improvement of some devices to be disclosed by the people.

Fig. 2 is the synoptic diagram of the carry-on dish of retractable USB interface, to reduce the risk of the cap of losing the protection USB interface.Shown in Fig. 2 A and Fig. 2 B, USB interface 22 characteristic of telescopic are mainly controlled by push button 21.When push button 21 being pushed to when preceding, shown in arrow among Fig. 2 A, then USB interface 22 is protruded the shell 23 of carry-on dish.On the contrary, when push button 21 is advanced towards the direction shown in the arrow of Fig. 2 B, then USB interface 22 is regained in the shell 23.In addition, shell 23 is provided with holes 231, and it is linear movable that push button 21 is able to.Yet holes 231 has destroyed the complete of shell 23 surfaces, and is very not attractive in appearance.

Fig. 3 A and Fig. 3 B illustrate the structure of the flash disk device of the 7th, 121, No. 852 patents of the U.S., comprise first interface 10, main body 12 and second interface 14.The upper and lower surface of main body 12 is respectively equipped with accommodation space 19, and the end in main body 12 is provided with first interface 10 and second interface 14 up and down respectively simultaneously.First interface 10 and second interface 14 can be placed in accommodation space 19 respectively.Shown in Fig. 3 B,

first interface

10 and 14 each rotation of second interface are placed in the accommodation space 19 of main body 12 freely, yet still have part to coat for accommodation space.The articulated section that the main body 12 and first interface 10 and second interface are 14 can produce the phenomenon that gets loose after long-term the use, cause first and second interface to be difficult for being accommodated in the accommodation space.

Therefore, core of the present invention is to propose the data memory device of the movable double nip of a kind of Improvement type to address the above problem, and utilizes the activity that the push button on the mobile carriage comes control interface that is arranged at.By push button being switched to different positions, two interfaces protruded or income data storage device shell in.Be different from the traditional data storage device, the present invention not only makes the problem of losing the carry-on dish cap of tradition not exist, and has also overcome the shortcoming of prior art.
