隨著轉接技術的快速發展，介面轉接裝置係廣泛地運用於人類的生活中並扮演越來越重要的腳色。舉例而言，當電子裝置所具有的資料傳輸與接收介面相異於擴充裝置時，介面轉接裝置可以作為轉接介面以連接電子裝置與擴充裝置，從而擴充電子裝置的基本功能。然而，目前而言，電子裝置並無法直接地透過介面轉接裝置連接外部電源以進行充電。換句話說，使用者必須先將介面轉接裝置由電子裝置上移除，而後再將電子裝置直接地連接至外部電源以進行充電，但此種作法將可能導致使用者不必要的人力消耗，從而降低使用者於使用介面轉接裝置時的體驗品質。With the rapid development of transit technology, interface switching devices are widely used in human life and play an increasingly important role. For example, when the data transmission and receiving interface of the electronic device is different from the expansion device, the interface switching device can be used as a switching interface to connect the electronic device and the expansion device, thereby expanding the basic functions of the electronic device. However, at present, the electronic device cannot directly connect to an external power source through the interface switching device for charging. In other words, the user must first remove the interface switching device from the electronic device and then directly connect the electronic device to an external power source for charging, but such an operation may result in unnecessary human consumption by the user. Thereby reducing the user experience quality when using the interface switching device.

When the OTG switching interface connects the electronic device to the expansion device, the voltage dividing module transmits the ground voltage to the electronic device; when the OTG switching interface connects the electronic device to the external power source, the voltage dividing module transmits the divided voltage to the electronic device Thus, an external power source is used to charge the electronic device.

第1A圖為依據本案揭示的實施例所繪製的介面轉接裝置100的方塊示意圖。如第1A圖所示，介面轉接裝置100包含OTG(On-The-Go)轉接介面110與分壓模組120。OTG轉接介面用以將電子裝置130連接至擴充裝置140或連接至外部電源150。分壓模組120用以接收電子裝置130的輸入電壓。舉例而言，電子裝置130可以由智慧型手機、平板電腦或任何行動式電子裝置所實施；擴充裝置140可以由隨身碟、滑鼠、鍵盤或任何可用以擴充電子裝置130的基本功能的裝置所實施。FIG. 1A is a block diagram of an interface switching device 100 according to an embodiment disclosed in the present disclosure. As shown in FIG. 1A, the interface switching device 100 includes an OTG (On-The-Go) switching interface 110 and a voltage dividing module 120. The OTG transfer interface is used to connect the electronic device 130 to the expansion device 140 or to the external power source 150. The voltage dividing module 120 is configured to receive an input voltage of the electronic device 130. For example, the electronic device 130 can be implemented by a smart phone, a tablet computer, or any mobile electronic device; the expansion device 140 can be powered by a flash drive, a mouse, a keyboard, or any device that can be used to expand the basic functions of the electronic device 130. Implementation.
當OTG轉接介面110用以將電子裝置130連接至擴充裝置140時，分壓模組120傳送接地電壓至電子裝置130；當OTG轉接介面110用以將電子裝置130連接至外部電源150時，分壓模組120傳送分壓電壓至電子裝置130，從而外部電源150用以為電子裝置130進行充電。舉例而言，當使用者透過OTG轉接介面110將電子裝置130選擇性地連接至擴充裝置140與連接至外部電源150時，分壓模組120可以傳送相應的電壓(如，接地電壓或分壓電壓)至電子裝置130，從而觸發電子裝置130進行相應地操作。When the OTG switching interface 110 is used to connect the electronic device 130 to the expansion device 140, the voltage dividing module 120 transmits a ground voltage to the electronic device 130; when the OTG switching interface 110 is used to connect the electronic device 130 to the external power source 150 The voltage dividing module 120 transmits the divided voltage to the electronic device 130, so that the external power source 150 is used to charge the electronic device 130. For example, when the user selectively connects the electronic device 130 to the expansion device 140 through the OTG switching interface 110 and connects to the external power source 150, the voltage dividing module 120 can transmit a corresponding voltage (eg, ground voltage or minute). The voltage is applied to the electronic device 130, thereby triggering the electronic device 130 to operate accordingly.
於一實施例中，請參閱第1B圖，第1B圖為依據本案揭示的實施例所繪製的分壓模組120的示意圖。如第1B圖所示，分壓模組120包含第一電阻R1與第二電阻R2，且第一電阻R1串連於第二電阻R2。當OTG轉接介面110用以將電子裝置130連接至外部電源150時，分壓模組可以依據第一電阻R1與第二電阻R2而將電子裝置130的輸入電壓V1進行分壓，從而產生並傳送分壓電壓V2(即，)至電子裝置130。In an embodiment, please refer to FIG. 1B. FIG. 1B is a schematic diagram of a voltage dividing module 120 according to an embodiment disclosed in the present disclosure. As shown in FIG. 1B, the voltage dividing module 120 includes a first resistor R1 and a second resistor R2, and the first resistor R1 is connected in series with the second resistor R2. When the OTG switching interface 110 is used to connect the electronic device 130 to the external power source 150, the voltage dividing module can divide the input voltage V1 of the electronic device 130 according to the first resistor R1 and the second resistor R2, thereby generating and Transmitting the divided voltage V2 (ie, ) to the electronic device 130.
於一實施例中，當電子裝置130接收到接地電壓後，電子裝置130啟動供電模式以為擴充裝置140進行供電。於另一實施例中，當電子裝置130啟動供電模式時，電子裝置130與擴充裝置140之間持續地進行資料傳輸與資料接收。舉例而言，當使用者透過OTG轉接介面110將電子裝置130連接至擴充裝置140，且分壓模組120傳送接地電壓至電子裝置130後，電子裝置130可以自動地啟動供電模式以為擴充裝置140進行供電，如此，擴充裝置140可以正常運作以接收來自電子裝置130的資料(如，透過隨身碟接收並儲存電子裝置130所傳送的資料)，抑或使用者可以透過擴充裝置140輸入指令以控制電子裝置130(如，透過滑鼠或鍵盤輸入指令至電子裝置130)，從而擴充電子裝置130的基本功能。In an embodiment, after the electronic device 130 receives the ground voltage, the electronic device 130 activates the power supply mode to supply power to the expansion device 140. In another embodiment, when the electronic device 130 activates the power supply mode, data transmission and data reception are continuously performed between the electronic device 130 and the expansion device 140. For example, when the user connects the electronic device 130 to the expansion device 140 through the OTG switching interface 110, and the voltage dividing module 120 transmits the ground voltage to the electronic device 130, the electronic device 130 can automatically activate the power supply mode to be the expansion device. The power is supplied to the device 140. The expansion device 140 can operate normally to receive data from the electronic device 130 (eg, receive and store data transmitted by the electronic device 130 through the flash drive), or the user can input commands through the expansion device 140 to control The electronic device 130 (eg, inputs commands to the electronic device 130 via a mouse or keyboard) expands the basic functionality of the electronic device 130.
於一實施例中，當電子裝置130接收到分壓電壓後，電子裝置130啟動充電模式以觸發外部電源150為電子裝置130進行充電。舉例而言，當使用者透過OTG轉接介面110將電子裝置130連接至外部電源150，且分壓模組120傳送分壓電壓至電子裝置130後，電子裝置130可以自動地啟動充電模式以觸發外部電源150，如此，外部電源150可以為電子裝置130進行充電，從而延長電子裝置130的運作時間。In an embodiment, after the electronic device 130 receives the divided voltage, the electronic device 130 activates the charging mode to trigger the external power source 150 to charge the electronic device 130. For example, when the user connects the electronic device 130 to the external power source 150 through the OTG switching interface 110, and the voltage dividing module 120 transmits the divided voltage to the electronic device 130, the electronic device 130 can automatically initiate the charging mode to trigger. The external power source 150, as such, the external power source 150 can charge the electronic device 130, thereby extending the operating time of the electronic device 130.
於另一實施例中，當電子裝置130啟動充電模式時，電子裝置130與擴充裝置140之間停止資料傳輸與資料接收。舉例而言，使用者可以透過OTG轉接介面110同時地將電子裝置130連接至擴充裝置140與外部電源150，然而，當電子裝置130啟動充電模式時，電子裝置130僅可以接收外部電源130所提供的電源以進行充電，並無法同時地為擴充裝置140進行供電以與擴充裝置140進行資料傳輸與資料接收。In another embodiment, when the electronic device 130 initiates the charging mode, data transmission and data reception are stopped between the electronic device 130 and the expansion device 140. For example, the user can simultaneously connect the electronic device 130 to the expansion device 140 and the external power source 150 through the OTG switching interface 110. However, when the electronic device 130 activates the charging mode, the electronic device 130 can only receive the external power source 130. The power supply is provided for charging, and the expansion device 140 cannot be simultaneously powered to perform data transmission and data reception with the expansion device 140.
於一實施例中，電子裝置130與擴充裝置140均具有通用序列匯流排(Universal Serial Bus，USB)介面，且OTG轉接介面110用以透過電子裝置130與擴充裝置140之通用序列匯流排介面連接電子裝置130與擴充裝置140。舉例而言，當電子裝置130具有通用序列匯流排介面時，電子裝置130可以透過通用序列匯流排介面的第一引腳傳送輸入電壓V1至分壓模組120，並透過通用序列匯流排介面的第二引腳接收接地電壓或分壓電壓V2。應瞭解到，上述實施例僅用以示範電子裝置130可行的實施方式，並非用以限制本案。舉例而言，電子裝置130與擴充裝置140所支援的資料傳輸與資料接收介面可以依據實際需求而進行相應地調整。In an embodiment, the electronic device 130 and the expansion device 140 both have a universal serial bus (USB) interface, and the OTG switching interface 110 is used to transmit the universal serial bus interface of the electronic device 130 and the expansion device 140. The electronic device 130 and the expansion device 140 are connected. For example, when the electronic device 130 has a universal serial bus interface, the electronic device 130 can transmit the input voltage V1 to the voltage dividing module 120 through the first pin of the universal serial bus interface, and pass through the universal serial bus interface. The second pin receives the ground voltage or the divided voltage V2. It should be understood that the above embodiments are merely used to demonstrate possible implementations of the electronic device 130, and are not intended to limit the present invention. For example, the data transmission and data receiving interfaces supported by the electronic device 130 and the expansion device 140 can be adjusted accordingly according to actual needs.

(eg, ground voltage or divided voltage) to the electronic device 130, thereby triggering the electronic device 130 to operate accordingly. In addition, the possible implementation manners of the voltage dividing module 120 described in the interface switching method 200 have been exemplified in detail in the above embodiments, and thus the detailed description thereof will not be repeated.
