Description

可縮短快速角色交換時間之連接埠擴充基座Port Docking Station for Faster Role Swap Times

本創作係關於一種擴充基座,尤指一種可縮短快速角色交換時間之連接埠擴充基座。This invention relates to a docking station, especially a port docking station that shortens the time for quick role swapping.

通用序列匯流排(Universal Serial Bus, USB以下簡稱USB)介面因為具有熱插拔與隨插即用的優點,在電子裝置產品中成為必備的連接介面。Universal Serial Bus (USB, hereinafter referred to as USB) interface has become a necessary connection interface in electronic device products because of its hot-swappable and plug-and-play advantages.

近年來,USB的版本不斷更新,到了USB-C版本時已可讓具有USB介面的電子裝置根據使用需求使該電子裝置於供電角色與被供電角色之間做快速的切換,此功能稱為快速角色交換(Fast Role Swap, FRS),以下簡稱FRS。In recent years, the USB version has been continuously updated. When the USB-C version is released, the electronic device with the USB interface can quickly switch between the power supply role and the power supply role according to the usage requirements. This function is called Fast Role Swap (FRS), hereinafter referred to as FRS.

舉例來說,連接埠擴充基座與外部電源連接時,可供電給與其連接的電子裝置(例如,筆記型電腦),但是當外部電源被拔除後,連接埠擴充基座會透過USB介面的配置通道(Configuration Channel, CC)來發出FRS訊息給筆記型電腦,以便與筆記型電腦進行快速角色交換程序,並改由筆記型電腦成為供電端。藉此,確保筆記型電腦與連接埠擴充基座之間的資料與影像傳輸不會被中斷。For example, when the port expansion base is connected to an external power source, it can supply power to the connected electronic device (for example, a notebook computer). However, when the external power supply is unplugged, the port expansion base will send a FRS message to the notebook computer through the configuration channel (Configuration Channel, CC) of the USB interface, so as to perform a fast role-swapping procedure with the notebook computer, and change the notebook computer to be the power supply terminal. In this way, it is ensured that the data and image transmission between the notebook computer and the docking station will not be interrupted.

然而,在筆記型電腦成為供電端前,其實還會持續對連接埠擴充基座汲取電力,因此,當筆記型電腦汲取電力的速度太快時,將使Vbus電壓低於正常運作位準,並導致連接埠擴充基座產生斷線問題。However, before the notebook computer becomes the power supply terminal, it will continue to draw power from the docking station. Therefore, when the notebook computer draws power too fast, the Vbus voltage will be lower than the normal operating level, and cause the docking station to disconnect.

有鑑於上述習知技術,創作人研發出一種可縮短快速角色交換時間之連接埠擴充基座,以提升連接埠擴充基座運作的穩定性。In view of the above-mentioned conventional technology, the creator has developed a port expansion base that can shorten the time for rapid role exchange, so as to improve the stability of the operation of the port expansion base.

在一實施例中,該加速單元用以對該第一電子裝置之Vbus電壓進行放電,以使該第一電子裝置提早偵測到該第一電子裝置之Vbus電壓下降至一第一閥值電壓與一第二閥值電壓的時間點。In one embodiment, the acceleration unit is used to discharge the Vbus voltage of the first electronic device, so that the first electronic device detects the time point when the Vbus voltage of the first electronic device drops to a first threshold voltage and a second threshold voltage earlier.

在一實施例中,該第二開關單元斷開該通往該第二連接埠之連接路徑且於一預定時間後,由該電力傳輸控制器控制該第二開關單元導通通往該第二連接埠之連接路徑。In one embodiment, the second switch unit disconnects the connection path to the second connection port and after a predetermined time, the power transmission controller controls the second switch unit to turn on the connection path to the second connection port.

為充分瞭解本創作之目的、特徵及功效,茲藉由下述具體之實施例,並配合所附之圖式,對本創作做一詳細說明,說明如後:In order to fully understand the purpose, characteristics and effects of this creation, I will give a detailed description of this creation by using the following specific examples and accompanying drawings, as follows:

請參考圖1A,係本創作一實施例之系統方塊圖。如圖1A所示, 連接埠擴充基座100包含有:第一開關單元10、第二開關單元12、儲能模組20、電力傳輸控制器30、第一偵測單元40、第二偵測單元42、加速單元50、第一連接埠110與第二連接埠120。第一電子裝置300(例如,筆記型電腦)具有連接埠310,並與第二連接埠120電性連接,以傳輸訊號、資料、影像與/或電力。Please refer to FIG. 1A, which is a system block diagram of an embodiment of the invention. As shown in FIG. 1A , the port expansion base 100 includes: a first switch unit 10 , a second switch unit 12 , an energy storage module 20 , a power transmission controller 30 , a first detection unit 40 , a second detection unit 42 , an acceleration unit 50 , a first connection port 110 and a second connection port 120 . The first electronic device 300 (for example, a notebook computer) has a connection port 310 and is electrically connected to the second connection port 120 to transmit signals, data, images and/or power.

第一開關單元10,與第一連接埠110電性連接,而第一連接埠110,與外部電源200電性連接。第一開關單元10可以例如是由PMOS或NMOS場效電晶體開關組成。另外,第一連接埠110可以例如是USB介面或其他規格的電源連接介面。在一實施例中,外部電源200可具有與第一連接埠110相同規格的連接埠。The first switch unit 10 is electrically connected to the first connection port 110 , and the first connection port 110 is electrically connected to the external power source 200 .

When the external power supply 200 is not powered, the second switch unit 12 is in an off state to disconnect the electrical connection path leading to the second connection port 120 , so that the connection port expansion base 100 stops supplying power to the first electronic device 300 . In this way, the problem of disconnection of the connection port expansion base 100 in the prior art can be avoided because the first electronic device 300 draws power too fast, causing the Vbus voltage to be lower than the normal operating level.

The energy storage module 20 is used for storing electric power. The energy storage module 20 can be, for example, a capacitor, a battery or a rechargeable battery. When the external power supply 200 is not supplying power, the energy storage module 20 supplies power to the docking station 100 itself, or supplies power to the first electronic device 300 .

電力傳輸控制器30,分別與第一開關單元10、第二開關單元12、儲能模組20及加速單元50電性連接。電力傳輸控制器30,用以根據外部電源200之供電狀態,控制由連接埠擴充基座100供電或從第一電子裝置300汲取電力。The power transmission controller 30 is electrically connected to the first switch unit 10 , the second switch unit 12 , the energy storage module 20 and the acceleration unit 50 respectively. The power transmission controller 30 is configured to control the power supply from the docking station 100 or draw power from the first electronic device 300 according to the power supply status of the external power supply 200 .

Likewise, the second detection unit 42 may be composed of a voltage detection circuit, for example.

請參考圖1B,係本創作另一實施例之系統方塊圖。如圖1B所示, 連接埠擴充基座150與圖1A的連接埠擴充基座100不同之處在於:具有第三連接埠130,其餘部分為相同或類似,於此不再贅述。Please refer to FIG. 1B, which is a system block diagram of another embodiment of the invention. As shown in FIG. 1B , the port expansion base 150 differs from the port expansion base 100 in FIG. 1A in that it has a third connection port 130 , and the rest are the same or similar, and will not be repeated here.

第三連接埠130,與第二電子裝置(例如,智慧型手機、平板電腦、智慧型手錶等)400電性連接。更具體的說,第三連接埠130透過纜線(圖中未標號)與第二電子裝置400的連接埠410電性連接。另外,第三連接埠130可以例如是USB介面。第三連接埠130與連接埠410為具有相同規格的傳輸介面。The third connection port 130 is electrically connected with the second electronic device (eg, smart phone, tablet computer, smart watch, etc.) 400 . More specifically, the third connection port 130 is electrically connected to the connection port 410 of the second electronic device 400 through a cable (not labeled in the figure). In addition, the third connection port 130 can be, for example, a USB interface. The third connection port 130 and the connection port 410 are transmission interfaces with the same specification.

在一實施例中,於外部電源200不供電時,可由儲能模組20供電給連接埠擴充基座150自身使用,以及供電至第二電子裝置400。In one embodiment, when the external power supply 200 is not powered, the energy storage module 20 can supply power to the docking station 150 itself and supply power to the second electronic device 400 .

接下來,請參考圖2,係本創作實施例之第一開關單元、第二開關單元、第一偵測單元與第二偵測單元之電路示意圖。如圖2所示,第一開關單元10與第二開關單元12分別由PMOS場效電晶體開關組成。第一偵測單元40與第二偵測單元42分別由NMOS場效電晶體開關與數個電阻組成。Next, please refer to FIG. 2 , which is a schematic circuit diagram of the first switch unit, the second switch unit, the first detection unit and the second detection unit of the present invention. As shown in FIG. 2 , the first switch unit 10 and the second switch unit 12 are respectively composed of PMOS field effect transistor switches. The first detection unit 40 and the second detection unit 42 are respectively composed of NMOS field effect transistor switches and several resistors.

第一偵測單元40可以持續偵測到外部電源200之Vbus電壓的變化。同樣的,第二偵測單元42可以持續偵測到第一電子裝置300之Vbus電壓的變化。於外部電源200不供電時,可由電力傳輸控制器30控制第二開關單元12為斷開狀態。The first detection unit 40 can continuously detect the change of the Vbus voltage of the external power supply 200 . Likewise, the second detection unit 42 can continuously detect the change of the Vbus voltage of the first electronic device 300 . When the external power supply 200 is not supplying power, the power transmission controller 30 can control the second switch unit 12 to be in an off state.

請參考圖3,係本創作實施例之加速單元之電路示意圖。如圖3所示,加速單元50包含有:第一電子開關Q1、第一電阻R1與第二電阻R2。第一電子開關Q1為NMOS場效電晶體開關。第一電子開關Q1的第一端(例如,閘極)G分別電性連接至控制訊號與第二電阻R2的一端。第二電阻R2的另一端電性連接至地。第一電子開關Q1的第二端(例如,源極)S電性連接至地。第一電子開關Q1的第三端(例如,汲極)D電性連接至第一電阻R1的一端。第一電阻R1的另一端電性連接至Vbus電壓。Please refer to FIG. 3 , which is a schematic circuit diagram of the acceleration unit of the embodiment of the present invention. As shown in FIG. 3 , the acceleration unit 50 includes: a first electronic switch Q1 , a first resistor R1 and a second resistor R2 . The first electronic switch Q1 is an NMOS field effect transistor switch. A first terminal (eg, a gate) G of the first electronic switch Q1 is electrically connected to the control signal and one terminal of the second resistor R2 respectively. The other end of the second resistor R2 is electrically connected to the ground. The second end (eg, source) S of the first electronic switch Q1 is electrically connected to the ground. The third terminal (eg, the drain) D of the first electronic switch Q1 is electrically connected to one terminal of the first resistor R1 . The other end of the first resistor R1 is electrically connected to the Vbus voltage.

舉例來說,當控制訊號為低電位(Low)時,第一電子開關Q1為斷開狀態,Vbus電壓不會被拉低。換言之,加速單元50不對Vbus電壓進行放電。當控制訊號為高電位(High)時,第一電子開關Q1為導通狀態,Vbus電壓會被拉低。換言之,加速單元50對Vbus電壓進行放電。所述的控制訊號可由電力傳輸控制器30發出。藉此,可使第一電子裝置300提早偵測到第一電子裝置300之Vbus電壓下降至第一閥值電壓與第二閥值電壓的時間點。For example, when the control signal is at low potential (Low), the first electronic switch Q1 is in an off state, and the Vbus voltage will not be pulled down. In other words, the acceleration unit 50 does not discharge the Vbus voltage. When the control signal is at a high potential (High), the first electronic switch Q1 is turned on, and the Vbus voltage is pulled down. In other words, the acceleration unit 50 discharges the Vbus voltage. The control signal can be sent by the power transmission controller 30 . Thereby, the first electronic device 300 can detect the time point when the Vbus voltage of the first electronic device 300 drops to the first threshold voltage and the second threshold voltage earlier.

另外,於第一偵測單元40偵測到第一電子裝置300之Vbus電壓低於第二閥值電壓(如圖4所示)時,電力傳輸控制器30關閉加速單元50並導通第二開關單元12,以使第一電子裝置300供電至連接埠擴充基座100。In addition, when the first detection unit 40 detects that the Vbus voltage of the first electronic device 300 is lower than the second threshold voltage (as shown in FIG. 4 ), the power transmission controller 30 turns off the acceleration unit 50 and turns on the second switch unit 12, so that the first electronic device 300 supplies power to the docking station 100.

請參考圖4,係本創作實施例之Vbus電壓變化曲線示意圖。如圖4所示,橫軸為時間,而縱軸為電壓。當第一偵測單元40偵測到外部電源200之Vbus電壓開始下降,電力傳輸控制器30會從配置通道發出FRS訊息給第一電子裝置300。待第一電子裝置300偵測到Vbus電壓 <第一閥值電壓(例如,vSafe5V (max)) 時,便會在Vbus電壓下降至第二閥值電壓(例如,vSafe5V(min))後的交換時間T3內將電源開啟,改由第一電子裝置300供電給連接埠擴充基座100。Please refer to FIG. 4 , which is a schematic diagram of the Vbus voltage change curve in the embodiment of the present invention. As shown in FIG. 4, the horizontal axis is time, and the vertical axis is voltage. When the first detection unit 40 detects that the Vbus voltage of the external power supply 200 starts to drop, the power transmission controller 30 sends an FRS message to the first electronic device 300 through the configuration channel. When the first electronic device 300 detects that the Vbus voltage is less than the first threshold voltage (for example, vSafe5V (max)), it will turn on the power supply within the switching time T3 after the Vbus voltage drops to the second threshold voltage (for example, vSafe5V (min)), and the first electronic device 300 will supply power to the port expansion base 100 instead.

在一實施例中,當第二開關單元12斷開通往第二連接埠120之連接路徑且於一預定時間T4後,由電力傳輸控制器30控制第二開關單元12再次導通通往第二連接埠120之連接路徑,以使第一電子裝置300供電給連接埠擴充基座100。In one embodiment, when the second switch unit 12 disconnects the connection path to the second connection port 120 and after a predetermined time T4, the power transmission controller 30 controls the second switch unit 12 to turn on the connection path to the second connection port 120 again, so that the first electronic device 300 supplies power to the port expansion base 100 .

在一實施例中,於第二偵測單元42偵測到第一電子裝置300之Vbus電壓由低轉高時,電力傳輸控制器30導通第二開關單元12,以使第一電子裝置300供電至連接埠擴充基座100。In one embodiment, when the second detection unit 42 detects that the Vbus voltage of the first electronic device 300 changes from low to high, the power transmission controller 30 turns on the second switch unit 12 so that the first electronic device 300 supplies power to the docking station 100 .

請參考圖5,係本創作實施例之快速角色交換之程序運作、電力路徑交換與Vbus電壓變化的對照示意圖。如圖5所示,最上方圖示呈現快速角色交換程序運作過程。中間圖示呈現連接埠擴充基座100與第一電子裝置300的電力路徑交換過程。最下方圖示呈現習知技術與本創作實施例的Vbus電壓變化對照圖。Please refer to FIG. 5 , which is a schematic diagram of the program operation of the rapid role exchange, the power path exchange and the Vbus voltage change in the embodiment of the invention. As shown in FIG. 5 , the uppermost diagram presents the operation process of the fast role exchange procedure. The middle diagram shows the power path exchange process between the docking station 100 and the first electronic device 300 . The bottom diagram presents a comparison chart of the Vbus voltage change between the conventional technology and the embodiment of the invention.

第一曲線60代表採用習知技術的FRS所偵測到第一電子裝置之Vbus電壓變化。第二曲線62代表採用本創作實施例的FRS所偵測到第一電子裝置之Vbus電壓變化。The first curve 60 represents the Vbus voltage change of the first electronic device detected by the FRS of the conventional technology. The second curve 62 represents the Vbus voltage change of the first electronic device detected by the FRS of the present invention.

第一曲線60在時間點T1時,才完成連接埠擴充基座100被供電與第一電子裝置300供電的交換程序,而第二曲線62在時間點T2時,已完成連接埠擴充基座100被供電與第一電子裝置300供電的交換程序。The first curve 60 is at the time point T1, the exchange process of the power supply of the port expansion base 100 and the first electronic device 300 is completed, and the second curve 62 is at the time point T2, the exchange process of the power supply of the port expansion base 100 and the first electronic device 300 has been completed.

由此可知,因為加速單元50的關係使得第二曲線62的下降斜率快於第一曲線62的下降斜率。藉此,可縮短FRS程序的交換時間。It can be seen that, due to the relationship of the acceleration unit 50 , the descending slope of the second curve 62 is faster than the descending slope of the first curve 62 . Thereby, the exchange time of the FRS program can be shortened.

綜上所述,由於本創作之可縮短快速角色交換時間之連接埠擴充基座,藉由加速單元對第一電子裝置之Vbus電壓進行放電,使第一電子裝置提早偵測到第一電子裝置之Vbus電壓下降至第一閥值電壓與第二閥值電壓的時間點,以提早完成快速角色交換程序。整體而言,除了可縮短快速角色交換時間外,還可避免連接埠擴充基座產生斷線問題,提升連接埠擴充基座的使用可靠度。To sum up, because the connection port expansion base of the present invention can shorten the fast role switching time, the acceleration unit discharges the Vbus voltage of the first electronic device, so that the first electronic device detects the time point when the Vbus voltage of the first electronic device drops to the first threshold voltage and the second threshold voltage earlier, so as to complete the fast role switching procedure earlier. On the whole, in addition to shortening the fast role exchange time, it can also avoid the disconnection problem of the port expansion base and improve the reliability of the use of the port expansion base.
