Description
本發明有關於一種行動電腦用擴充裝置，且特別是一種可切換無線/有線傳輸模式之行動電腦用擴充裝置。 The present invention relates to an expansion device for a mobile computer, and more particularly to an expansion device for a mobile computer that can switch between wireless/wired transmission modes.
行動電腦例如筆記型電腦、平板電腦或手持裝置如智慧型手機被設計成方便攜帶，故體積、重量和訊號接頭的種類和數量往往收到限制。因為行動電腦本身所具有的埠接頭種類或數量的限制，使用行動電腦的使用者在將行動電腦連接其他設備時可能會遇到接頭不夠(例如：通用序列匯流排(USB)的接頭不夠用)，或需要轉接頭的問題(例如：顯示介面埠的種類如D-Sub、DVI、DisplayPort(DP)或HDMI不符合)。因此，製造商提供了行動電腦用的擴充裝置以作為行動電腦的擴充介面等功能。 Mobile computers such as notebook computers, tablets or handheld devices such as smart phones are designed to be portable, so the size and weight of the connector and the number of signal connectors are often limited. Because of the type or number of connectors that the mobile computer itself has, users who use mobile computers may encounter insufficient connectors when connecting the mobile computer to other devices (for example, the universal serial bus (USB) connector is not enough) , or a problem with the adapter (for example, the type of display interface such as D-Sub, DVI, DisplayPort (DP) or HDMI does not match). As a result, manufacturers have provided expansion devices for mobile computers as functions such as an expansion interface for mobile computers.
行動電腦用的擴充裝置可分為有線與無線兩種。使用者利用有線擴充裝置連接行動電腦時需要將行動電腦與擴充裝置透過.實體的傳輸線直接連接，如此可能減少了攜帶的方便性。而無線擴充裝置解決了有線擴充裝置的方便性不足的問題。 Expansion devices for mobile computers can be divided into wired and wireless. When a user uses a cable expansion device to connect to a mobile computer, the mobile computer and the expansion device need to be directly connected through the physical transmission line, which may reduce the convenience of carrying. The wireless expansion device solves the problem of insufficient convenience of the cable expansion device.
然而，如圖1所示，當環境中有多台無線網路裝置1、2、3使用相同的通道時，會產生封包碰撞現象。所述無線網路裝置1、3、3例如是無線擴充裝置(例如：WiFi-Dock)或無線網路存取點(Access Point)。這些無線網路裝置無法避免封包碰撞的問題發生，此時會使得吞吐率(Throughput)下降，進而影響到檔案以及 影像傳輸的速度，例如影像傳輸的延遲(Latency)變大，最終則影響到用戶的使用體驗。再者，傳統的WiFi 2.4GHz以及5GHz的操作頻帶有限，因此在頻譜擁塞的環境下，如何滿足多人的使用環境(辦公室)將是嚴苛的挑戰。 However, as shown in FIG. 1, when multiple wireless network devices 1, 2, and 3 in the environment use the same channel, packet collision occurs. The wireless network device 1, 3, 3 is, for example, a wireless expansion device (for example: WiFi-Dock) or a wireless network access point (Access Point). These wireless network devices cannot avoid the problem of packet collisions, which will cause the throughput to drop, which will affect the files and The speed of image transmission, such as the delay of image transmission, becomes large, which ultimately affects the user experience. Furthermore, the traditional WiFi 2.4GHz and 5GHz operating bands are limited, so how to meet the multi-person environment (office) in a spectrum-congested environment will be a severe challenge.
本發明實施例提供一種可切換無線/有線傳輸模式之行動電腦用擴充裝置，讓行動電腦的使用者可以透過無線或有線連結的方式存取區域網路(LAN)與廣域網路(WAN)，並且同時使用擴充裝置所連接的各種周邊裝置的功能。 Embodiments of the present invention provide a mobile computer expansion device that can switch between a wireless/wired transmission mode, so that a user of a mobile computer can access a local area network (LAN) and a wide area network (WAN) through a wireless or wired connection, and At the same time, the functions of various peripheral devices connected to the expansion device are used.

On the other hand, when the first port 42 is not connected to the mobile computer, the plurality of second ports of the mobile computer and the extended output/input unit 44 transmit signals to each other through the access point router 41 in the wireless transmission mode. In actual implementation, when the spectrum is congested, the user can switch to the mode of wired transmission without affecting the work and the use experience. Exemplary two switching modes are described herein: (1) After the mobile computer is connected to the expansion device (the first port 42) through the universal serial bus transmission line, the expansion device automatically switches to the wired transmission mode. (2) After the mobile computer is connected to the expansion device through the universal serial bus transmission line, the user must press the physical button to switch to the wired transmission mode. However, based on the convenience of the user's actual operation, the switching mode is not limited to the above two.
