Description of the Invention: [Technical Field] The present invention relates to a data storage device having a USB connector, and more particularly to a data storage device for an active USB connector of a host computer. [Prior Art]
近幾年來，主機裝置（如個人電腦）上的資料擷取裝 置，隨著科技日新月異而有驚人的發展。舉例來說，為達 到資料傳輸目的，眾多藉由許多新發展的技術來耦接於電 腦系統的週邊設備，包含USB、IEEE1394、以及其他介面。 其中，以USB提供給週邊設備的連接性與傳輸速度較傳統 序列埠來得佳。USB的廣泛應用（如隨身碟或俗稱“大拇哥，， 的隨身碟），大為提升資料傳輸與擷取的便利性。除此之 外，USB具有隨插即用的介面，可搜尋並下載合適該週邊 設備的驅動程式，其隨插即用的特性帶來絕佳的資料可攜 性。然，USB接頭（或插頭）亦受溼氣或靜電的影響而造成損 害。因此，一般隨身碟通常具有帽蓋來保護USB接頭 因暴露造成損害。 ^凊參照圖1所示，係習知具有USB插頭的標準隨身碟示 意圖。一般來說，爲保護USB接頭12，會附帶一個帽蓋u。 «•亥幅蓋11在套住USB接頭12後，因此帽蓋11與外殼丨3合成 :整體形狀，可保護USB接頭12以及電子零件的部份（未圖 示）但於使用本產品時，會將帽蓋11自外殼13取下，因此 容易遺失’甚為不便。一旦遺失帽蓋u，接頭12則容 1339464 、 易損壞。因此，保護USB接頭的作用亦顯重要，遂有一些 裝置的增益改良為人所揭示。 圖2為可伸縮USB接頭隨身碟的示意圖，以降低遺失保 護USB接頭的帽蓋的風險。如圖2A與圖2B所示，USB接頭 22可伸縮的特性主要由推鈕21所控制。當將推鈕21推向前 時’如圖2A中箭號所示，則USB接頭22凸出隨身碟的外殼 23。相反地，當將推鈕21朝圖2B之箭號所示之方向推進， 則USB接頭22收回外殼23内。此外，外殼23設有破孔231， • 使推鈕21得以線性活動。然而’破孔231破壞了外殼23表面 的完整，不甚美觀。 圖3繪示習知技術美國第6,808,400號專利之隨身碟裝 置。圖3A係一 USB接頭33隱藏於一外殼37内，該USB接頭 33連接於PCB35，該PCB35的頂部有複數個彈簧39，係頂 在該外殼37之一頂層内部與PCB35的頂部。此時，該彈脊 39疋處於伸張狀態的。如圖3B所示，由於結構上撥動鍵 311、延伸臂313與扣片315為一體的，故當定位結構31的撥 • 動鍵311被按住並往上推動時，故扣片315亦會向上移動並 鑽入扣孔373中。另一方面，撥動鍵311與pCB35相連接， 故sothatUSB接頭33經由USB出口 371突出於外殼37，如圖 3B。此時，彈簧39是處於壓縮狀態的，只要輕輕撥動撥 317,藉由彈簣的彈力，即可令該扣片315脫離該扣孔， 回復到圖3A所示狀態。 如上所述，美國第6,808,400號專利藉由彈簧、扣片、 以及扣孔以使USB接頭凸出於外殼並定位。當彈簧處於壓 縮狀態’則USB接頭突出於外殼。反之，當彈赞為伸張狀 1339464 =夺二SB接頭則隱藏於外殼。利用彈簧的特性雖可克服 傳統Ik身碟的缺點’卻無法降低生產成本。此外 ，期使用後，亦產生彈性疲乏導致性能不 此; 因此，本發明的核心為提出一種改良的資料儲^置因:解 ::上述問碭。利用旋轉驅動機構來控制咖接頭的活動。 透過轉動旋轉驅動機構’ USB接頭得以凸出或收 f裝置外殼内。不同於傳統儲存褒置，本遺 ^統隨㈣帽蓋㈣題不復存在，亦克服了習知技 【發明内容】 有鑒於習知技藝受限於上述問題，本發 供一種具有活動刪接頭的資料儲存 2 = 頭的使用壽命。 Λ、長USB接 依照本發明之一觀點，提供一種資料儲存裝置，包括 圮憶杈組、連接於記憶模組的us 的殼mSB接頭穿越殼體 謂接頭的活動載架、以及旋轉驅動機構，可將 轉換為線性運動，以移動USB接頭。 運動 根據本案構想，活動載架具有第—凸部斑第 純轉驅動機構所驅動，藉由推抵第— :’ 因此推動USB接頭。 興第一凸部’ 根據本案構想，當旋轉驅動機構 部時，接頭自開口凸出，當旋轉 心方向相反的另一方向轉動並推抵第二凸部：機= 1339464 接頭收入殼體。 根據本案構想，資料儲存 的定位架，當USB接頭自開歩包括設置於殼體 臂 根據本案構想，定位架包括出=:定位刪接頭。 避免USB接頭移動。 括”活動載架嚙合的延伸 時 根據本案構想’當旋轉 刪接頭職釋放。域_該另—方向轉動 根據本案構想，延伸臂有撓性。 引導3本案構想，旋轉驅動機構包括相絲接的凸輪和 根據本案構想， 根據本案構想， 根據本案構想， 鑰匙圈孔。 殼體包括線性引導活動載架的軌。 殼體設有線性引導活動載架的槽。 貝料儲存裝置進一歩包括設於殼體的 根據本案構想，f料儲存裝置進—歩包括防寫切換裝 置，以避免儲存於資料儲存裝置的資料被更改。 根據本案構想’資料儲存裝置包括USB隨身碟。 >依，本發明之另一觀點，提供一種資料儲存裝置，包 括β己隐模、、且連接έ己憶模組的主機介面接頭、可容納記憶 模‘'且的Λ又體使主機介面接頭穿越殼體的開口、固持記憶 模組與主機介面接頭的活動載架、以及將旋轉運動轉換為 線性運動的旋轉驅動機構，以移動主機介面接頭。 根據本案構想’主機介面接頭包括USB介面接頭、 IEEE-1394介面接頭、以及eSATA介面接頭。 1-64 【實施方式】 體現本發明特徵與優點的一此 中詳細敘述。本發明能夠在尤/實施例將在後段的說明 化’皆不脫離本發明的範圍，且上具有各種的變 上當作說明之用，而非用以限明及圖式在本質 =4A與4B為本發明之資料儲存裝置的示意圖。資料儲 含殼體41、承載USB接頭和記憶模組(未圖示) ~ ^驅動活動載架42的旋轉驅動機構43。 =41有Μ的空間來容納咖接頭和記憶模組，並且有 =411，使⑽接頭得以穿越。在轉動旋轉驅動機齡產 ί的驅動力之影響下，活動載架C自開口4Η伸出，承載於 其上的USB接頭亦是。 、 如圖示，殼體包含孔412 ’可用來懸掛鑰匙圈或吊繩。 不同於，2A與2B所7F之習知隨身碟，用來覆蓋料儲存裝置 40的，蓋413和底蓋414的表面並無破孔❶因此，頂蓋413 和底蓋414的表面仍保持完整，可做為個性化或美化殼體41 之用三舉例來說’製造商可將精^設計的圖樣或商標打印 在頂蓋或底蓋的表面，以達防堵不肖人士仿冒之效。 一圖5A和5B繪示本發明資料儲存裝置的第一實施例。如 圖示，資料儲存裝置50包含殼體51、活動載架52、凸輪53卜 以及供活動載架52滑動於其上的引導轨54。活動載架52可 承載記憶模組（未圖示）與USB接頭（未圖示）。在其他實施例 中，USB接頭可為1EEE-1394介面接頭、eSATA介面接頭、 或其他介面接頭。凸輪53b與引導單元53a樞接，共同運作 將旋轉運動轉換為線性運動，以控制活動載架52的移動。 1339464 藉由轉動引導單元53a旋轉運動所產生扭力，如圖5A的箭 號A所示，將凸輪53b推向設置於活動載架52上的第一凸部 52丨’活動載架52經由開口 51丨凸出於殼體51，如圖中虛線 箭號所示。 將引導單元53a往圖5B的箭號B所示的方向轉動，所 產生的旋轉運動傳送到凸輪53b，凸輪53b隨之擺向推抵活 動載架52上的第二凸部522，促使活動載架52沿著引導軌54 進行線性活動，收入殼體51，如圖5B之箭號所示。本實施 φ 例的引導執54為圖5 A所示的槽，在其他實施例中亦可以軌 來實施本發明。此外，頂蓋513與底蓋（未圖示）可為覆蓋殼 體51之用。殼體51進一歩包含孔512，可用來懸掛鑰匙環或 鏈繩’方便攜帶本資料儲存裝置。In recent years, data acquisition devices on host devices (such as personal computers) have grown dramatically with the rapid development of technology. For example, for data transmission purposes, a number of peripherals coupled to the computer system, including USB, IEEE 1394, and other interfaces, are supported by a number of newly developed technologies. Among them, the connectivity and transmission speed provided by USB to peripheral devices is better than the traditional serial. USB's wide-ranging applications (such as flash drives or flash drives, commonly known as "big thumb,") greatly enhance the convenience of data transfer and retrieval. In addition, USB has a plug-and-play interface that can be searched and downloaded. The driver of the peripheral device has excellent plug-and-play characteristics for excellent data portability. However, the USB connector (or plug) is also damaged by moisture or static electricity. Therefore, the general pen drive usually There is a cap to protect the USB connector from damage caused by exposure. ^ Refer to the standard flash drive with USB plug as shown in Figure 1. In general, to protect the USB connector 12, a cap u will be attached. « • The hood cover 11 is wrapped around the USB connector 12, so the cap 11 is combined with the case 丨3: the overall shape protects the USB connector 12 and the electronic component (not shown) but when using the product, The cap 11 is removed from the outer casing 13 and is therefore easily lost. It is inconvenient. Once the cap u is lost, the connector 12 is 1339464 and is easily damaged. Therefore, it is also important to protect the USB connector, and some devices have gains. Improved to Figure 2 is a schematic diagram of a retractable USB connector flash drive to reduce the risk of losing the cap of the protected USB connector. As shown in Figures 2A and 2B, the telescopic characteristics of the USB connector 22 are mainly controlled by the push button 21. When the push button 21 is pushed forward as shown by the arrow in Fig. 2A, the USB connector 22 protrudes from the outer casing 23 of the flash drive. Conversely, when the push button 21 is directed to the direction indicated by the arrow of Fig. 2B In advance, the USB connector 22 is retracted into the outer casing 23. Further, the outer casing 23 is provided with a hole 231, which allows the push button 21 to move linearly. However, the 'broken hole 231 breaks the integrity of the surface of the outer casing 23, which is not aesthetically pleasing. FIG. 3A is a USB connector 33 hidden in a casing 37. The USB connector 33 is connected to the PCB 35. The top of the PCB 35 has a plurality of springs 39 at the top of the PCB 35. The top of one of the outer casing 37 and the top of the PCB 35. At this time, the ridge 39 is in an extended state. As shown in FIG. 3B, since the structural toggle button 311, the extension arm 313 and the buckle 315 are integrated, When the dial key 311 of the positioning structure 31 is pressed and pushed up, The cleat 315 also moves upward and drills into the clasp hole 373. On the other hand, the toggle button 311 is connected to the pCB 35, so that the USB connector 33 protrudes from the outer casing 37 via the USB outlet 371, as shown in Fig. 3B. At this time, the spring 39 It is in a compressed state, and by simply dialing the dial 317, the elastic force of the magazine can be used to release the buckle 315 from the buckle hole and return to the state shown in Fig. 3A. As described above, the US Patent No. 6,808,400 The USB connector protrudes from the housing and is positioned by the spring, the clasp, and the buckle hole. When the spring is in a compressed state, the USB connector protrudes from the outer casing. Conversely, when the bullet is stretched, the 1339464 = the second SB joint is hidden in the outer casing. The use of springs can overcome the shortcomings of traditional Ik bodies, but it does not reduce production costs. In addition, after the use, the elastic fatigue is also caused to cause performance failure; therefore, the core of the present invention is to propose an improved data storage factor: solution: the above question.
