請參閱圖1所示，本案之擴充式無線通訊裝置10，其係與一外接裝置40相配合，外接裝置40包含一第二連接介面42及至少一外部天線44（在此係以一個外部天線44為例），此擴充式無線通訊裝置10包含至少一內建天線12（在此係以一個內建天線12為例）、一射頻收發模組14、一第一連接介面16、一連接介面控制器18、至少一切換元件20（在此係以一個切換元件20為例）以及一控制判斷模組22。其中，擴充式無線通訊裝置10係內建在一電子裝置（圖中未示）中，且第一連接介面16係為電子裝置原本既有的對外連接介面，以透過此第一連接介面16來連接外接裝置40。Please refer to FIG. 1 , the expandable wireless communication device 10 of the present invention cooperates with an external device 40, the external device 40 includes a second connection interface 42 and at least one external antenna 44 (herein, an external antenna 44 is used as an example), the expandable wireless communication device 10 includes at least one built-in antenna 12 (herein, a built-in antenna 12 is used as an example), a radio frequency transceiver module 14, a first connection interface 16, a connection interface controller 18, at least one switching element 20 (herein, a switching element 20 is used as an example) and a control judgment module 22. The extended wireless communication device 10 is built in an electronic device (not shown), and the first connection interface 16 is an existing external connection interface of the electronic device, so as to connect to the external device 40 through the first connection interface 16 .

在擴充式無線通訊裝置10中，射頻收發模組14係電性連接內建天線12，使射頻收發模組14可以透過內建天線12發射或接收一射頻訊號。第一連接介面16係作為對外的接口，並可與第二連接介面42相配合，連接介面控制器18透過複數傳輸線24電性連接第一連接介面16，且連接介面控制器18可連接至後端之中央處理器（圖中未示），以據此傳輸資料。切換元件20係為一三端元件，即一對二的切換開關，例如單極雙刀開關（SPDT），切換元件20之一端連接至第一連接介面16，另二端則連接至連接介面控制器18及射頻收發模組14，以選擇性建立第一連接介面16與連接介面控制器18間之一傳輸通道或是建立第一連接介面16與射頻收發模組14間之一射頻通道。控制判斷模組22係電性連接切換元件20，控制判斷模組22係為產生一控制訊號之控制電路，並判斷外接裝置40是否透過第二連接介面42連接至第一連接介面16。當第一連接介面16未插接有任何外接裝置，或是第一連接介面16係連接有不具天線設計的其他外接裝置時，切換元件20會維持現有狀態，保持在連接介面控制器18的位置，以導通第一連接介面16與連接介面控制器18之間的傳輸通道。當控制判斷模組22確認具有外部天線44之外接裝置40已透過第二連接介面42連接至第一連接介面16時，控制判斷模組22會對應產生一控制訊號，並利用控制訊號控制切換元件20作動而切換至射頻收發模組14的位置，使切換元件20響應控制訊號而選擇建立第一連接介面16與射頻收發模組14間之射頻通道。基此，擴充式無線通訊裝置10由原本的一支內建天線12，透過第一連接介面16與第二連接介面42所增加之外部天線44而擴增為二支天線。In the extended wireless communication device 10, the RF transceiver module 14 is electrically connected to the built-in antenna 12, so that the RF transceiver module 14 can transmit or receive a RF signal through the built-in antenna 12. The first connection interface 16 is used as an external interface and can be matched with the second connection interface 42. The connection interface controller 18 is electrically connected to the first connection interface 16 through a plurality of transmission lines 24, and the connection interface controller 18 can be connected to the central processing unit (not shown) at the back end to transmit data accordingly. The switching element 20 is a three-terminal element, i.e., a one-to-two switching switch, such as a single-pole double-pole switch (SPDT). One end of the switching element 20 is connected to the first connection interface 16, and the other two ends are connected to the connection interface controller 18 and the RF transceiver module 14 to selectively establish a transmission channel between the first connection interface 16 and the connection interface controller 18 or to establish an RF channel between the first connection interface 16 and the RF transceiver module 14. The control determination module 22 is electrically connected to the switching element 20. The control determination module 22 is a control circuit that generates a control signal and determines whether the external device 40 is connected to the first connection interface 16 through the second connection interface 42. When the first connection interface 16 is not plugged into any external device, or the first connection interface 16 is connected to other external devices without antenna design, the switch element 20 will maintain the current state and remain at the position of the connection interface controller 18 to conduct the transmission channel between the first connection interface 16 and the connection interface controller 18. When the control judgment module 22 confirms that the external device 40 with an external antenna 44 has been connected to the first connection interface 16 through the second connection interface 42, the control judgment module 22 will generate a control signal accordingly, and use the control signal to control the switch element 20 to switch to the position of the RF transceiver module 14, so that the switch element 20 responds to the control signal and selects to establish the RF channel between the first connection interface 16 and the RF transceiver module 14. Therefore, the expandable wireless communication device 10 is expanded from one built-in antenna 12 to two antennas through the external antenna 44 added by the first connection interface 16 and the second connection interface 42 .

在一實施例中，第一連接介面16及第二連接介面42係分別為可互相匹配連接的一通用序列匯流排（USB）連接介面、一通用序列匯流排C型（USB type C）連接介面或是一高畫質多媒體介面（High Definition Multimedia Interface，HDMI），端看電子裝置原有內建之連接介面的類型而定，但本案不以此為限。In one embodiment, the first connection interface 16 and the second connection interface 42 are respectively a Universal Serial Bus (USB) connection interface, a Universal Serial Bus C type (USB type C) connection interface or a High Definition Multimedia Interface (HDMI) that can be matched and connected to each other, depending on the type of the connection interface originally built into the electronic device, but the present case is not limited to this.

請參閱圖2所示，本案之擴充式無線通訊裝置10，其係與一外接裝置40相配合，外接裝置40包含一第二連接介面42、一第一外部天線46以及一第二外部天線48，此擴充式無線通訊裝置10包含一第一內建天線26、一第二內建天線28、一射頻收發模組14、一第一連接介面16、一連接介面控制器18、一第一切換元件30、一第二切換元件32以及一控制判斷模組22。Please refer to FIG. 2 , the expandable wireless communication device 10 of the present invention cooperates with an external device 40, the external device 40 includes a second connection interface 42, a first external antenna 46 and a second external antenna 48, the expandable wireless communication device 10 includes a first built-in antenna 26, a second built-in antenna 28, a radio frequency transceiver module 14, a first connection interface 16, a connection interface controller 18, a first switching element 30, a second switching element 32 and a control determination module 22.

如圖2所示，在擴充式無線通訊裝置10中，射頻收發模組14係電性連接第一內建天線26及第二內建天線28，使射頻收發模組14可以透過第一內建天線26或/及第二內建天線28發射或接收一射頻訊號。第一連接介面16係作為對外的接口，並可與第二連接介面42相配合，連接介面控制器18透過複數傳輸線24電性連接第一連接介面16，以據此傳輸資料。第一切換元件30及第二切換元件32分別為一對二的切換開關，例如單極雙刀開關（SPDT），第一切換元件30之一端連接至第一連接介面16，另二端則連接至連接介面控制器18及射頻收發模組14，以選擇性建立第一連接介面16與連接介面控制器18間之一第一傳輸通道或是建立第一連接介面16與射頻收發模組14間之一第一射頻通道，此第一射頻通道係提供給第一外部天線46使用；第二切換元件32之一端亦連接至第一連接介面16，另二端連接至連接介面控制器18及射頻收發模組14，以選擇性建立第一連接介面16與連接介面控制器18間之一第二傳輸通道或是建立第一連接介面16與射頻收發模組14間之一第二射頻通道，此第二射頻通道係提供給第二外部天線48使用。控制判斷模組22係電性連接第一切換元件30及第二切換元件32，控制判斷模組22判斷外接裝置40是否透過第二連接介面42連接至第一連接介面16。As shown in FIG. 2 , in the extended wireless communication device 10, the RF transceiver module 14 is electrically connected to the first built-in antenna 26 and the second built-in antenna 28, so that the RF transceiver module 14 can transmit or receive a RF signal through the first built-in antenna 26 and/or the second built-in antenna 28. The first connection interface 16 is used as an external interface and can cooperate with the second connection interface 42. The connection interface controller 18 is electrically connected to the first connection interface 16 through a plurality of transmission lines 24 to transmit data accordingly. The first switching element 30 and the second switching element 32 are one-to-two switching switches, such as single-pole double-pole switches (SPDT). One end of the first switching element 30 is connected to the first connection interface 16, and the other two ends are connected to the connection interface controller 18 and the RF transceiver module 14 to selectively establish a first transmission channel between the first connection interface 16 and the connection interface controller 18 or a first RF channel between the first connection interface 16 and the RF transceiver module 14. The first RF channel is provided for the first external antenna 46; one end of the second switching element 32 is also connected to the first connection interface 16, and the other two ends are connected to the connection interface controller 18 and the RF transceiver module 14 to selectively establish a second transmission channel between the first connection interface 16 and the connection interface controller 18 or to establish a second RF channel between the first connection interface 16 and the RF transceiver module 14, and the second RF channel is provided for the second external antenna 48. The control determination module 22 is electrically connected to the first switching element 30 and the second switching element 32, and the control determination module 22 determines whether the external device 40 is connected to the first connection interface 16 through the second connection interface 42.

當第一連接介面16未插接有任何外接裝置40，或是第一連接介面16係連接有不具天線設計的其他外接裝置時，第一切換元件30及第二切換元件32皆會維持現有狀態，保持在連接介面控制器18的位置，以導通第一連接介面16與連接介面控制器18之間的第一傳輸通道及第二傳輸通道。當控制判斷模組22確認具有第一外部天線46與第二外部天線48之外接裝置40已透過第二連接介面42連接至第一連接介面16時，控制判斷模組22會對應產生一控制訊號，並利用控制訊號控制第一切換元件30及第二切換元件32作動而切換至射頻收發模組14，使第一切換元件30響應控制訊號而選擇建立第一連接介面16與射頻收發模組14間之第一射頻通道以及使第二切換元件32響應控制訊號而選擇建立第一連接介面16與射頻收發模組14間之第二射頻通道，此時射頻收發模組14除了可以使用第一內建天線26及第二內建天線28之外，亦可透過第一切換元件30（第一射頻通道）、第一連接介面16及第二連接介面42而使用第一外部天線46，以及透過第二切換元件32（第二射頻通道）、第一連接介面16及第二連接介面42而使用第二外部天線48。基此，擴充式無線通訊裝置10由原本的二支內建天線（第一內建天線26及第二內建天線28），透過第一連接介面16與第二連接介面42所增加之外部天線（第一外部天線46及第二外部天線48）而擴增為四支天線。When no external device 40 is plugged into the first connection interface 16, or the first connection interface 16 is connected to other external devices without an antenna design, the first switching element 30 and the second switching element 32 will maintain their existing state and remain at the position of the connection interface controller 18 to conduct the first transmission channel and the second transmission channel between the first connection interface 16 and the connection interface controller 18. When the control judgment module 22 confirms that the external device 40 having the first external antenna 46 and the second external antenna 48 has been connected to the first connection interface 16 through the second connection interface 42, the control judgment module 22 will generate a control signal accordingly, and use the control signal to control the first switching element 30 and the second switching element 32 to switch to the RF transceiver module 14, so that the first switching element 30 responds to the control signal and selects to establish the first RF channel between the first connection interface 16 and the RF transceiver module 14 and the second switching element In response to the control signal, the first connection interface 16 and the second RF channel between the RF transceiver module 14 are selected to establish. At this time, the RF transceiver module 14 can use the first built-in antenna 26 and the second built-in antenna 28, and can also use the first external antenna 46 through the first switching element 30 (first RF channel), the first connection interface 16 and the second connection interface 42, and use the second external antenna 48 through the second switching element 32 (second RF channel), the first connection interface 16 and the second connection interface 42. Based on this, the extended wireless communication device 10 is expanded from the original two built-in antennas (the first built-in antenna 26 and the second built-in antenna 28) to four antennas through the external antennas (the first external antenna 46 and the second external antenna 48) added through the first connection interface 16 and the second connection interface 42.

The first switching element 30 and the second switching element 32 are respectively one-to-two switching switches, such as single-pole double-pole switches. One end of the first switching element 30 is connected to the RF transceiver module 14, and the other two ends are connected to the built-in antenna 12 and the second switching element 32. One end of the second switching element 32 is connected to the first connection interface 16, and the other two ends are connected to the connection interface controller 18 and the first switching element 30, so as to selectively establish the RF transceiver module 14 through the first switching element. An internal RF channel between the built-in antenna 12 or an external RF channel between the RF transceiver module 14 and the first connection interface 16 is established in cooperation with the second switching element 32, and an external RF channel or a transmission channel between the first connection interface 16 and the connection interface controller 18 is selectively established through the second switching element 32, so as to provide the internal RF channel for the built-in antenna 12 and the external RF channel for the external antenna 44. The control determination module 22 is electrically connected to the first switching element 30 and the second switching element 32, and the control determination module 22 determines whether the external device 40 is connected to the first connection interface 16 through the second connection interface 42. When no external device 40 is plugged into the first connection interface 16, or the first connection interface 16 is connected to other external devices without an antenna design, the first switching element 30 and the second switching element 32 will maintain their existing states. The first switching element 30 remains in the position of connecting to the built-in antenna 12, and the second switching element 32 remains in the position of connecting to the interface controller 18, so as to use the built-in antenna 12 to send and receive signals and conduct the transmission channel between the first connection interface 16 and the connection interface controller 18. When the control judgment module 22 confirms that the external device 40 with the external antenna 44 has been connected to the first connection interface 16 through the second connection interface 42, the control judgment module 22 will generate a control signal accordingly, and use the control signal to control the movement of the first switching element 30 and the second switching element 32, so as to switch the first switching element 30 to a position connected to the second switching element 32 and switch the second switching element 32 to a position connected to the first switching element 30, so that the first switching element 30 and the second switching element 32 respond to the control signal and choose to establish an external RF channel between the RF transceiver module 14 and the first connection interface 16 to switch to use the external antenna 44 to transmit and receive signals. Based on this, the expansion type wireless communication device 10 switches the built-in antenna 12 originally used to the external antenna 44 through the cooperation of the first switching element 30 and the second switching element 32. Therefore, the expansion type wireless communication device 10 can choose to use the built-in antenna 12 or the external antenna 44 as needed.

請參閱圖1、圖2及圖3所示，擴充式無線通訊裝置10使用之控制判斷模組22可依需求而有不同的電路設計。在一實施例中，控制判斷模組22係為一獨立的電路元件；在另一實施例中，此控制判斷模組22也可以直接內建於一中央處理器（圖中未示）內。1, 2 and 3, the control and determination module 22 used in the extended wireless communication device 10 can have different circuit designs according to the requirements. In one embodiment, the control and determination module 22 is an independent circuit element; in another embodiment, the control and determination module 22 can also be directly built into a central processing unit (not shown).

在一實施例中，請參閱圖4所示，由於控制判斷模組22需要知道外接裝置40是否有接入，所以可以配合霍爾感測元件（Hall sensor）34之工作機制來確認外接裝置40的存在與否。具體而言，擴充式無線通訊裝置10更包括一霍爾感測元件34，霍爾感測元件34係電性連接至控制判斷模組22，並且，在外接裝置40內對應設置一磁性元件50，例如磁鐵，使霍爾感測元件34能夠對應到外接裝置40內的磁性元件50。當霍爾感測元件34偵測到磁性元件50時，表示外接裝置40之第二連接介面42已連接至第一連接介面16，霍爾感測元件34會產生一偵測訊號給控制判斷模組22，使控制判斷模組22產生控制訊號來控制切換元件20。In one embodiment, please refer to FIG. 4 , since the control judgment module 22 needs to know whether the external device 40 is connected, the working mechanism of the Hall sensor 34 can be used to confirm the existence of the external device 40. Specifically, the extended wireless communication device 10 further includes a Hall sensor 34, which is electrically connected to the control judgment module 22, and a magnetic element 50, such as a magnet, is correspondingly disposed in the external device 40, so that the Hall sensor 34 can correspond to the magnetic element 50 in the external device 40. When the Hall sensor 34 detects the magnetic element 50 , it indicates that the second connection interface 42 of the external device 40 has been connected to the first connection interface 16 . The Hall sensor 34 generates a detection signal to the control judgment module 22 , so that the control judgment module 22 generates a control signal to control the switching element 20 .

在一實施例中，如圖1至圖3所示，本案使用之外接裝置40係為一外接配件，例如，外部天線設計在風扇、搖桿等主動的配件裝置上，此時，由於外接裝置40內建有一積體電路（IC）（圖中未示），所以具有擴充式無線通訊裝置10之電子裝置可以透過確認積體電路的連線訊號來判斷外接裝置40已透過第二連接介面42連接至第一連接介面16，並使控制判斷模組22產生控制訊號，以便讓圖1之切換元件20以及圖2與圖3之第一切換元件30及第二切換元件32來切換路徑。In one embodiment, as shown in FIGS. 1 to 3 , the external device 40 used in the present case is an external accessory, for example, an external antenna is designed on an active accessory device such as a fan or a joystick. At this time, since an integrated circuit (IC) (not shown) is built into the external device 40, the electronic device having the extended wireless communication device 10 can determine that the external device 40 has been connected to the first connection interface 16 through the second connection interface 42 by confirming the connection signal of the integrated circuit, and make the control determination module 22 generate a control signal so as to allow the switching element 20 of FIG. 1 and the first switching element 30 and the second switching element 32 of FIGS. 2 and 3 to switch the path.

本案之擴充式無線通訊裝置10適用於一般具有無線通訊功能之電子裝置，例如筆記型電腦、平板電腦或是行動電話等，但應用的電子裝置不限於此。舉例來說，如圖1至圖3所示，電子裝置為筆記型電腦時，第一連接介面16及第二連接介面42可以為一般通用序列匯流排連接介面、通用序列匯流排C型連接介面或是一高畫質多媒體介面；電子裝置為平板電腦或行動電話時，第一連接介面16及第二連接介面42可以為通用序列匯流排C型連接介面。以通用序列匯流排C型連接介面為例，本案可以透過與C型連接介面中的SBU1接腳及SBU2接腳共用，來完成天線的切換或擴增，也可以選擇其他訊號接腳來共用，本案不以此為限。基此，本案提出之擴充式無線通訊裝置10可以沿用電子裝置原有的連接介面（第一連接介面16），而無需再額外增加新的連接介面。The expandable wireless communication device 10 of the present invention is applicable to general electronic devices with wireless communication functions, such as laptops, tablet computers or mobile phones, but the applicable electronic devices are not limited thereto. For example, as shown in FIG. 1 to FIG. 3 , when the electronic device is a laptop, the first connection interface 16 and the second connection interface 42 can be a general USB connection interface, a USB Type-C connection interface or a high-definition multimedia interface; when the electronic device is a tablet computer or a mobile phone, the first connection interface 16 and the second connection interface 42 can be a USB Type-C connection interface. Taking the universal serial bus type C connection interface as an example, the present invention can complete the switching or expansion of the antenna by sharing the SBU1 pin and the SBU2 pin in the type C connection interface, and can also select other signal pins for sharing, and the present invention is not limited to this. Based on this, the expansion type wireless communication device 10 proposed in the present invention can continue to use the original connection interface (first connection interface 16) of the electronic device without adding a new connection interface.

綜上所述，本案係為一種擴充式無線通訊裝置，其係在解決電子裝置之天線空間侷限的問題，以透過電子裝置原有的連接介面來連接外部天線，使天線數量增加，進而達到天線切換或天線擴增之目的，並且可加強收訊能力或加強射頻功能。因此，本案實為一種透過既有連接介面並協同切換元件之作用來達到天線切換或天線擴增之擴充式無線通訊裝置，並在電子產品之天線空間侷限的前提下，有效增加天線數量或是在內部天線被外部使用環境影響時，進行天線切換，以達到增加效能之功效。In summary, this case is an expandable wireless communication device that solves the problem of antenna space limitation of electronic devices by connecting external antennas through the original connection interface of the electronic device to increase the number of antennas, thereby achieving the purpose of antenna switching or antenna expansion, and can enhance the signal receiving ability or enhance the radio frequency function. Therefore, this case is actually an expandable wireless communication device that achieves antenna switching or antenna expansion through the existing connection interface and the role of the coordinated switching element, and under the premise of the antenna space limitation of the electronic product, effectively increases the number of antennas or switches the antenna when the internal antenna is affected by the external use environment to achieve the effect of increasing performance.
