In other embodiments, the connection device 104 can be integrated into the expansion device 102. In an embodiment, the connection device 104 is fully integrated into the expansion device 102.
本發明並不限定電子裝置112的種類。在本實施例 中，電子裝置112可為一行動電話。在其它實施例中，電子裝置112可為任何需要供電的電子裝置或手持式電子裝置，如平板電腦、個人數位助理(PDA)…等。 The invention does not limit the type of electronic device 112. In this embodiment The electronic device 112 can be a mobile phone. In other embodiments, the electronic device 112 can be any electronic device or handheld electronic device that requires power, such as a tablet computer, a personal digital assistant (PDA), and the like.
當電子裝置112透過連接裝置104耦接擴充裝置 102時，擴充裝置102可根據外部電源提供一電源予電子裝置112，用以對電子裝置112充電。另一方面，擴充裝置102亦可根據外部電源提供一電源予週邊裝置(如鍵盤108及滑鼠110)。 在電子裝置112充電的同時，擴充裝置102還可將週邊裝置(如鍵盤108及滑鼠110)所提供的信號提供予電子裝置112，或是將電子裝置112輸出的信號提供予週邊裝置(如隨身碟，未繪示)。 When the electronic device 112 is coupled to the expansion device through the connection device 104 At 102 o'clock, the expansion device 102 can provide a power source to the electronic device 112 for charging the electronic device 112 according to an external power source. On the other hand, the expansion device 102 can also provide a power source to peripheral devices (such as the keyboard 108 and the mouse 110) according to an external power source. While the electronic device 112 is being charged, the expansion device 102 can also provide signals provided by peripheral devices (such as the keyboard 108 and the mouse 110) to the electronic device 112, or provide signals output by the electronic device 112 to peripheral devices (eg, The flash drive, not shown).
此外，擴充裝置102可視為一集線器(Hub)，用以擴 充一主機的連接埠。當一具有運算能力的裝置(如電子裝置112)耦接擴充裝置102時，則此具有運算能力的裝置可作為一主機 (Host)。舉例而言，若擴充裝置102為一USB集線器，則透過USB集線器可使多個USB週邊裝置連接主機，例如鍵盤108及滑鼠110等多個USB週邊裝置，以提供使用者操控電子裝置112。當擴充裝置102作為一USB集線器時，主機可能透過或不透過連接裝置104耦接擴充裝置102。 In addition, the expansion device 102 can be regarded as a hub for expansion. Fill the connection of a host. When a computing device (such as the electronic device 112) is coupled to the expansion device 102, the computing device can serve as a host. (Host). For example, if the expansion device 102 is a USB hub, a plurality of USB peripheral devices can be connected to the host through a USB hub, such as a plurality of USB peripheral devices such as the keyboard 108 and the mouse 110, to provide the user with the electronic device 112. When the expansion device 102 acts as a USB hub, the host may couple the expansion device 102 with or without the connection device 104.
值得注意的是，當擴充裝置102具有多個連接埠 時，依照連接埠所連接的裝置，這些連接埠可被區分成上行埠(Upstream Port)與下行埠(Downstream Port)。上行埠連接電子裝置112等具有運算能力的主機裝置，下行埠連接週邊裝置(如鍵盤108、滑鼠110、隨身碟等)，其中擴充裝置102可提供電源予連接下行埠的週邊裝置。值得一提的是，以往的擴充裝置的上行埠所連接的電子裝置雖然具備運算能力，但擴充裝置卻無法提供電源予連接上行埠的電子裝置以進行充電。換言之，耦接上行埠的電子裝置其電源只能來自於內部的電池或是另外耦接的外部電源。因此，在使用上有其不便利性。然而，本發明之擴充裝置102是可以提供電源予電子裝置112而進行充電。如此一來，透過擴充裝置102，耦接上行埠的電子裝置112可進行運算、並可與連接下行埠的週邊裝置進行溝通，而且擴充裝置102可以同時提供電源予上行埠的電子裝置112及下行埠的週邊裝置。因此，可大幅提高擴充裝置102的使用性。關於本發明之擴充裝置102的傳輸系統，可參考如下的詳細說明。 It is worth noting that when the expansion device 102 has multiple ports埠 These ports can be divided into an Upstream Port and a Downstream Port according to the devices connected to the port. The host device having the computing capability, such as the uplink connection electronic device 112, is connected to the peripheral device (such as the keyboard 108, the mouse 110, the flash drive, etc.), and the expansion device 102 can provide power to the peripheral device connected to the downstream device. It is worth mentioning that although the electronic device connected to the upstream device of the conventional expansion device has computing power, the expansion device cannot provide power to the electronic device connected to the upstream device for charging. In other words, the electronic device coupled to the upstream device can only be powered by an internal battery or an externally coupled external power source. Therefore, it is inconvenient in use. However, the expansion device 102 of the present invention can provide power to the electronic device 112 for charging. In this way, through the expansion device 102, the electronic device 112 coupled to the uplink device can perform calculations and can communicate with peripheral devices connected to the downlink device, and the expansion device 102 can simultaneously provide power to the upstream electronic device 112 and downlink.

詳細的說明是，當連接埠213為USB 2.0 Micro-B型 連接器、USB 2.0 Mini-B型連接器、或是USB 3.0 Micro-B型連接器其中之一時，由於B型連接器具有一ID接腳，此ID接腳可透過連接裝置104而與電子裝置112的ID接腳(連接埠231的其中一接腳)耦接，並且透過阻抗裝置R下拉至地GND，藉此讓電子裝置112辨識出擴充裝置102可作為一充電裝置。 The detailed description is when the port 213 is USB 2.0 Micro-B type When the connector, the USB 2.0 Mini-B connector, or the USB 3.0 Micro-B connector is one of the connectors, since the B-type connector has an ID pin, the ID pin can communicate with the electronic device 112 through the connection device 104. The ID pin (one of the pins of the port 231) is coupled and pulled down to the ground GND through the impedance device R, thereby allowing the electronic device 112 to recognize that the expansion device 102 can function as a charging device.
本發明並不限定阻抗裝置R的設置位置。只要能夠 將連接埠213、221或222的一ID接腳下拉至地GND的位置，均可設置阻抗裝置R。在本實施例中，阻抗裝置R係整合在擴充裝置102之中。在其它實施例中，阻抗裝置R可整合在連接裝置104之中，用以將連接埠221或222的一接腳(如ID接腳)耦接至地GND。 The present invention does not limit the installation position of the impedance device R. As long as The impedance device R can be provided by pulling down an ID pin of the port 213, 221 or 222 to the ground GND. In the present embodiment, the impedance device R is integrated in the expansion device 102. In other embodiments, the impedance device R can be integrated in the connection device 104 to couple a pin (such as an ID pin) of the connection port 221 or 222 to the ground GND.
在其它實施例中，連接裝置104的形式可為具有二 連接埠221及222的一連接線(Cable)或是一電路板(PCB)。舉例而言，當連接裝置104為電路板形式時，則連接裝置104的傳輸模組223具有許多走線(trace)，用以負責連接埠221與222之間的溝通，而這些走線與連接埠221與222配置於電路板上。在其它實施例中，連接裝置104可完全或部分整合於擴充裝置102之中。關於連接裝置104整合於擴充裝置102的圖示，請參照第3圖，稍後將詳細說明。 In other embodiments, the connection device 104 can be in the form of two A cable (Cable) connecting the ports 221 and 222 or a circuit board (PCB). For example, when the connection device 104 is in the form of a circuit board, the transmission module 223 of the connection device 104 has a plurality of traces for communicating between the ports 221 and 222, and the wires and connections are connected.埠221 and 222 are disposed on the circuit board. In other embodiments, the connection device 104 can be fully or partially integrated into the expansion device 102. For an illustration of the connection device 104 integrated in the expansion device 102, please refer to FIG. 3, which will be described in detail later.
電子裝置112具有一連接埠231以及一主體單元 232，其中該主體單元232具備運算能力。本發明並不限定連接埠231的種類。在一可能實施例中，連接埠231可為USB 2.0 Micro-B型連接器、USB 2.0 Mini-B型連接器、或是USB 3.0 Micro-B型連接器其中之一。連接埠231的種類可與連接裝置104的連接埠222匹配。當電子裝置112透過連接裝置104耦接擴充裝置102時，主體單元232判斷連接埠231的ID接腳的位準。 若連接埠231的ID接腳被阻抗裝置R耦接至地GND時，主體單元232得知擴充裝置102為一充電裝置，因此，接收擴充裝置102所提供的充電電源。 The electronic device 112 has a connection port 231 and a main body unit 232, wherein the main unit 232 has computing power. The invention does not limit the type of port 231. In a possible embodiment, the port 231 can be one of a USB 2.0 Micro-B type connector, a USB 2.0 Mini-B type connector, or a USB 3.0 Micro-B type connector. The type of port 231 can be matched to the port 222 of the connection device 104. When the electronic device 112 is coupled to the expansion device 102 through the connection device 104, the main body unit 232 determines the level of the ID pin of the connection port 231. When the ID pin of the port 231 is coupled to the ground GND by the impedance device R, the body unit 232 knows that the expansion device 102 is a charging device, and therefore receives the charging power provided by the expansion device 102.
值得一提的是，若電子裝置112為手持電子裝置 時，在大多數的實施例中，連接埠231為B型連接器。假設連接埠213也為B型連接器，因此可透過具有二個B型連接器的連接裝置104來耦接擴充裝置102。而且，配合阻抗裝置R的設置，電子裝置112將可進行充電。另外，若擴充裝置102作為集線器，並配置有週邊裝置時，則電子裝置112還可與週邊裝置進行溝通。 It is worth mentioning that if the electronic device 112 is a handheld electronic device In most embodiments, the port 231 is a type B connector. Assuming that the port 213 is also a B-type connector, the expansion device 102 can be coupled through a connection device 104 having two B-type connectors. Moreover, in conjunction with the setting of the impedance device R, the electronic device 112 will be chargeable. Further, when the expansion device 102 is used as a hub and a peripheral device is disposed, the electronic device 112 can also communicate with the peripheral device.
本發明並不限定主體單元232的內部電路架構。在 一可能實施例中，主體單元232具有許多微處理器、微控制器、邏輯電路組合、記憶體…等元件。在本實施例中，主體單元232的內部電路架構與電子裝置112的種類有關。只要能夠達到電子裝置112的功能的電路架構，均可作為主體單元232。 The present invention does not limit the internal circuit architecture of the main unit 232. in In one possible embodiment, the body unit 232 has a number of components such as a microprocessor, a microcontroller, a logic circuit combination, a memory, and the like. In the present embodiment, the internal circuit architecture of the main unit 232 is related to the type of the electronic device 112. As long as the circuit architecture capable of achieving the function of the electronic device 112 can be used as the main unit 232.
由於擴充裝置102同時具有充電及集線器的功 能，故可大幅增加擴充裝置102的便利性。再者，連接埠213、221、222、231係為較為普遍的接頭，因此，使用者不需額外 購買特製的連接裝置，便可使擴充裝置102對電子裝置112充電，因此，增加充電動作的便利性。 Since the expansion device 102 has both charging and hub power Therefore, the convenience of the expansion device 102 can be greatly increased. Furthermore, the ports 213, 221, 222, and 231 are more common joints, so the user does not need to add extra By purchasing a special connection device, the expansion device 102 can charge the electronic device 112, thereby increasing the convenience of the charging operation.
第3圖為本發明之傳輸系統之另一可能示意圖。第 3圖相似第2圖，不同之處在於連接裝置104整合於擴充裝置102之中。在本實施例中，只要將第2圖中的連接埠213置換成連接埠222後，擴充裝置102便可直接耦接電子裝置112，而不需透過連接裝置104。因此，可降低傳輸系統的元件成本。由於第3圖裡的各元件的動作原理均已說明如上，故不再贅述。 Figure 3 is another possible schematic diagram of the transmission system of the present invention. First 3 is similar to FIG. 2 except that the connection device 104 is integrated into the expansion device 102. In this embodiment, the expansion device 102 can be directly coupled to the electronic device 112 without replacing the connection device 104 by replacing the connection port 213 in FIG. 2 with the connection port 222. Therefore, the component cost of the transmission system can be reduced. Since the principle of operation of each component in Fig. 3 has been described above, it will not be described again.
