[0038] As Figures 1 to 4 shown, the present application provides a connection system 1, including:

[0039] Docking station 11;

[0040] Electronic device 12;

[0041] Connection line 13, a first end of the connection line 13 is provided with a first plug 131, and the connection line 13 is connected to the electronic device 12 through the first plug 131;

[0042] The connection line 13 includes a detection device, and the detection device is arranged at the first plug 131 for sensing the movement of the first plug 131 relative to the electronic device 12, and when the first plug 131 is connected to the electronic device 12, transmitting a first signal or a second signal to the electronic device, where the first signal is used to represent that the state of the first plug 131 and the electronic device 12 is switched to a connected state, and the second signal is used to represent that the state of the first plug 131 is switched to a disconnected state.

[0043] A connection system 1 provided by an embodiment of the present application includes a computing device, an electronic device 12, and a connection line 13. The connection line 13 is used to connect the electronic device 12 to the computing device so that information interaction can be performed between the computing device and the electronic device 12 through the connection line 13. A first plug 131 is provided at the first end of the connection line 13, and the connection line 13 is connected to the electronic device 12 through the first plug 131. The connection line 13 includes a detection device, and the detection device is provided at the first plug 131. When the first plug 131 is about to be inserted into or pulled out of the electronic device 12, the detection device can sense it, and after the first plug 131 is connected to the electronic device 12, the sensed first signal or the upcoming second signal is transmitted to the electronic device 12, so that the electronic device 12 can know in advance that it is connected to the computing device and know in advance and be about to disconnect from the computing device. After receiving the first signal, the electronic device 12 automatically starts the computing device in the external docking station 11 without the need to restart the electronic device 12; after the electronic device 12 receives the upcoming second signal, the computing device in the external docking station 11 is automatically unloaded, so that there is no need to restart the computer, so that hot plugging is supported between the electronic device 12 and the external docking station 11, and it is not affected by the mutual power-on sequence. And the stable operation and status synchronization of the system, thus ensuring the user experience.

[0044] In this embodiment, the docking station includes a computing device, and the computing device can be a GPU or an NPU, etc.

[0045] As Figure 1 shown, in the embodiment of the present application, the detection device includes a photosensitive component 141. The photosensitive component 141 is provided at the first plug 131. When the first plug 131 is about to be plugged into or unplugged from the electronic device 12, at least part of the photosensitive component 141 is blocked, the light received by the photosensitive component 141 changes, and the photosensitive component 141 sends a first signal or a second signal to the electronic device 12 according to the change in the received light.

[0046] In this embodiment, a photosensitive component 141 is provided at the first plug connector 131 of the connection line 13. As a detection device, the photosensitive component 141 can sense the change of light. When the first plug connector 131 is about to be inserted into the electronic device 12 or about to be pulled out of the electronic device 12, the user's hand will approach the first plug connector 131, so that the light received by the photosensitive component 141 will change. The photosensitive component 141 determines whether the first plug connector 131 is about to be inserted into or pulled out of the electronic device 12 according to the change of the received light. If the first plug-in component is not inserted into the electronic device 12 before the photosensitive component 141 receives the light change, and after the photosensitive component 141 receives the light change and the first plug-in component is inserted into the electronic device 12, the photosensitive component 141 sends a first signal to the electronic device 12, and the electronic device 12 automatically starts the data processing module in the external expansion dock 11 according to the first signal, so that the electronic device 12 does not need to be restarted; if the first plug-in component is inserted into the electronic device 12 before the photosensitive component 141 receives the light change, and after the photosensitive component 141 receives the light change, the photosensitive component 141 sends a second signal to the electronic device 12, and the electronic device 12 automatically unloads the data processing module in the external expansion dock 11 according to the second signal, so that the electronic device 12 does not need to be restarted, thus solving the problem of hot pluggability between the electronic device 12 and the external expansion dock 11.

[0047] As Figure 2 shown, in the embodiment of the present application, the detection device includes a pressing structure 142. The pressing structure 142 is provided at the first plug. When the first plug connector 131 and the electronic device 12 are about to be plugged or unplugged, the pressing structure 142 is pressed, and the pressing structure 142 sends a first signal or a second signal to the electronic device 12 after being pressed.

[0048] In this embodiment, a pressing structure 142 is provided at the first plug connector 131 of the connecting line 13. The pressing structure 142 serves as a detection device and can sense when it is pressed. When the first plug connector 131 is about to be inserted into the electronic device 12 or about to be pulled out of the electronic device 12, the user will contact and press the first plug connector 131. Since the pressing structure 142 is provided on the first plug connector 131, when the user presses the first plug connector 131, the pressing structure 142 will be pressed simultaneously. Thus, the change in the pressure received by the pressing structure 142 is detected. The pressing structure 142 determines whether the first plug connector 131 is about to be inserted into or pulled out of the electronic device 12 based on the change in the received pressure. If the first plug connector has not been inserted into the electronic device 12 before the pressing structure 142 senses a pressure change, and after the pressing structure 142 senses the pressure change and the first plug connector is inserted into the electronic device 12, the pressing structure 142 sends a first signal to the electronic device 12. The electronic device 12 automatically starts the data processing module in the external docking station 11 according to the first signal, so that the electronic device 12 does not need to be restarted. If the first plug connector is inserted into the electronic device 12 before the pressing structure 142 senses a pressure change, and after the pressing structure 142 senses the light change, the pressing structure 142 sends a second signal to the electronic device 12. The electronic device 12 automatically unloads the data processing module in the external docking station 11 according to the second signal, so that the electronic device 12 does not need to be restarted, thus solving the problem of supporting hot plugging between the electronic device 12 and the external docking station 11.

[0049] As Figure 3 shown, in the embodiment of the present application, the detection device includes a second plug connector 143. The second plug connector 143 is inserted and pulled out simultaneously with the first plug connector 131 to send a first signal or a second signal to the electronic device 12 when the synchronous plug connector is plugged into or unplugged from the electronic device 12.

[0050] In this embodiment, a second plug connector 143 is disposed adjacent to the first plug connector 131. The second plug connector 143 is a hot pluggable structure, and the second plug connector 143 is plugged and unplugged synchronously with the first plug connector 131. When the first plug connector 131 is inserted into the electronic device 12, the second plug connector 143 is inserted into the electronic device 12 synchronously with the first plug connector 131. When the second plug connector 143 is inserted into the electronic device 12, a first signal of the second plug connector 143 is transmitted to the electronic device 12. The electronic device 12 receives the first signal and automatically starts the data processing module in the external docking station 11 according to the first signal, so that the electronic device 12 does not need to be restarted. When the second plug connector 143 is pulled out of the electronic device 12, a second signal of the second plug connector 143 is transmitted to the electronic device 12. The electronic device 12 receives the second signal, and the electronic device 12 automatically starts the data processing module in the external docking station 11 according to the second signal, so that the electronic device 12 does not need to be restarted, thereby solving the problem of supporting hot plugging between the electronic device 12 and the external docking station 11.

[0051] As Figure 4 shown, in the embodiment of the present application, the electronic device 12 has a first connector 15, and the electronic device 12 is connected to the first plug connector 131 at the first end of the connection line 13 through the first connector 15;

[0052] The docking station 11 has a second connector 16, and the docking station 11 is connected to the second end of the connection line 13;

[0053] When the docking station 11 and the electronic device 12 are connected through the connection line 13, the connection line 13 between the first connector 15 and the second connector 16 has a transmission channel for signal interaction between the electronic device 12 and the docking station 11.

[0054] In this embodiment, the first end of the connection line 13 is connected to the electronic device 12 through the first plug connector 131, and the second end of the connection line 13 is connected to the docking station 11. Thus, the connection between the electronic device 12 and the docking station 11 is realized through the connection line 13. The electronic device 12 has a first connector 15, and the docking station 11 has a second connector 16. When the electronic device 12 and the docking station 11 are connected through the connection line 13, the first connector 15 of the electronic device 12 is connected to the second connector 16 of the docking station 11 through the connection line 13. And the connection line 13 has a transmission channel, and the first connector 15 and the second connector 16 are connected through the transmission channel of the connection line 13. The transmission channel is used to transmit signals between the first connector 15 and the second connector 16, so as to realize the information interaction between the first connector 15 and the second connector 16. To achieve that after the electronic device 12 receives the first signal or is about to receive the second signal, the signal for automatically starting the data processing module in the docking station 11 or the signal for automatically unloading the data processing module is transmitted through the transmission channel to the second connector 16 of the docking station 11 through the first connector 15. The second connector 16 then transmits the signal to the corresponding component to automatically start the data processing module in the docking station 11 or automatically unload the data processing module. Thus, when the connector of the docking station 11 is plugged in or unplugged from the electronic device 12, the electronic device 12 does not need to be restarted, realizing hot plugging.

[0055] As Figure 5 shown, in the embodiment of the present application, the first connector 15 has a first level signal pin 151, and the second connector 16 has a second level signal pin 161;

[0056] When the docking station 11 is connected to the electronic device 12 through the connection line 13, there is a first channel between the first level signal pin 151 and the second level signal pin 161. The first level signal pin 151 transmits the level signal to the second level signal pin 161 through the first channel, and the docking station 11 judges the on / off state of the electronic device 12 according to the level signal;

[0057] When the level signal is a high level, the electronic device 12 is in the on state;

[0058] When the level signal is a low level, the electronic device 12 is in the off state.

[0059] In this embodiment, the connection line 13 connected to the docking station 11 can be inserted into the electronic device 12 or pulled out from the electronic device 12 when the electronic device 12 is on, and can also be inserted into the electronic device 12 or pulled out from the electronic device 12 when the electronic device 12 is off.

[0060] In this embodiment, before the electronic device 12 is powered on, the connection line 13 connected to the docking station 11 is inserted into the electronic device 12. After the electronic device 12 is powered on, the level signal of the 3VS of the electronic device 12 changes from low level to high level. The first level signal pin 151 of the first connector 15 transmits the high-level signal to the second level signal pin 161 of the second connector 16 through the first channel. After receiving the high-level signal, the second connector 16 can determine that the electronic device 12 is in the powered-on state, and then powers on the data processing module according to the received high-level signal.

[0061] In this embodiment, after the electronic device 12 is powered on, the connection line 13 connected to the docking station 11 is inserted into the electronic device 12. The first level signal pin 151 of the first connector 15 of the electronic device 12 transmits the high-level signal to the second level signal pin 161 of the second connector 16 through the first channel. After receiving the high-level signal, the second connector 16 can determine that the electronic device 12 is in the powered-on state, and then the data processing module is powered on according to the received high-level signal.

[0062] In this embodiment, after the electronic device 12 is powered off, the connection line 13 connected to the docking station 11 is pulled out from the electronic device 12. After the electronic device 12 is powered off, the level signal of the 3VS of the electronic device 12 changes from high level to low level. The first level signal pin 151 of the first connector 15 transmits the low-level signal to the second level signal pin 161 of the second connector 16 through the first channel. After receiving the low-level signal, the second connector 16 can determine that the electronic device 12 is in the powered-off state, and then the data processing module also performs the power-off process.

[0063] In this embodiment, the first level signal pin 151 of the first connector 15 is the 3VS pin of A1 of the electronic device 12, and the second level signal pin 161 of the second connector 16 is the 3VS_Oculink of A1 of the docking station 11.

[0064] As Figure 5 shown, in the embodiment of the present application, the first connector 15 has a first reset signal pin 152, and the second connector 16 has a second reset signal pin 162;

[0065] When the docking station 11 is connected to the electronic device 12 through the connection line 13, there is a second channel between the first reset signal pin 152 and the second reset signal pin 162. The first reset signal pin 152 transmits the reset signal to the second reset signal pin 162 through the second channel, and the docking station 11 is initialized according to the reset signal.

[0066] In this embodiment, when the first plug connector connected to the docking station 11 is plugged into the electronic device 12 and the electronic device 12 is in the powered-on state, the first reset signal pin 152 of the first connector 15 sends a reset signal to the second reset signal pin 162 of the second connector 16 through the second channel. After receiving the reset signal, the second reset signal pin 162 of the second connector 16 initializes the data processing module according to the reset signal for subsequent operation.

[0067] In this embodiment, the first reset signal pin 152 of the first connector 15 is the PLREST pin of B12 of the electronic device 12, and the second reset signal pin 162 of the second connector 16 is PERST_R of A12 of the docking station 11.

[0068] As Figure 5 shown, in the embodiment of the present application, the first connector 15 has a first clock signal pin 153, and the second connector 16 has a second clock signal pin 163 and a clock signal receiving pin;

[0069] When the docking station 11 and the electronic device 12 are connected through the connection line 13, there is a third channel between the first clock signal pin 153 and the second clock signal pin 163. The second clock signal pin 163 sends a clock request signal to the first clock signal pin 153 through the second channel. The first clock signal pin 153 sends a clock signal to the clock signal receiving pin according to the clock request signal, and the second clock signal pin 163 receives the clock signal to identify the electronic device 12.

[0070] In this embodiment, after the docking station 11 initializes itself according to the reset signal, the second clock signal pin 163 on the second connector 16 sends a clock request signal OCU_CLK_REQUEST to the first clock signal pin on the first connector 15 through the third channel. The first clock signal pin 153 sends a clock signal to the clock signal receiving pin according to the clock request signal. The first clock signal pin 153 of the first connector 15 transmits the clock signal to the second clock signal pin 163 of the second connector 16 through the third channel. Then, the docking station 11 identifies the electronic device 12 according to the clock signal, and enables the electronic device 12 to successfully identify the docking station 11 and synchronize the status. Then, the data processing module transmits a confirmation signal to the first connector, so that the electronic device successfully identifies the graphics card.

[0071] In this embodiment, the first clock signal pin 153 of the first connector 15 is the CLK Request pin of B13 of the electronic device 12, and the second clock signal pin 163 of the second connector 16 is CLKRequest_R of A13 of the docking station 11.

[0072] As Figure 6 shown, in the embodiment of the present application, the docking station 11 further includes a data processing module, and the data processing module is connected to the second connector 16 and is configured to receive and start and initialize the data processing module according to the reset signal.

[0073] In this embodiment, the docking station 11 includes a second connector 16 and a data processing module. The second connector 16 is connected to the data processing module. After the second level signal pin 161 of the second connector 16 receives a high level, the second connector 16 will send the high level to the data processing module, and the data processing module starts the docking station 11 according to the high level; after the second level signal pin 161 of the second connector 16 receives a low level, the second connector 16 will send the low level to the data processing module, and the data processing module shuts down the data processing module according to the low level; after the second reset signal pin 162 of the second connector 16 receives a reset signal, the second connector 16 will send the reset signal to the data processing module, and the data processing module is initialized according to the reset signal; after the second clock signal pin 163 of the second connector 16 receives a reset signal, the second connector 16 will send a clock signal to the data processing module, and the data processing module performs link training according to the clock signal to achieve status synchronization, and then the data processing module transmits an acknowledgment signal to the first connector, so that the electronic device can successfully recognize the graphics card

[0074] In the embodiment of the present application, the electronic device 12 can run a first system, and the basic input / output is connected to the first connector 15 and is configured to receive a first signal or a second signal sent by the first plug 131, and start and initialize the data processing module of the docking station 11 according to the first signal, and shut down the data processing module of the docking station 11 according to the second signal.

[0075] In this embodiment, the electronic device 12 includes a first plug connector 131, a detection device, a first connector 15, and a first system. The detection device is connected to the first system through the first plug connector 131. The first system is further connected to the first connector 15. The detection device can be used to sense whether the first plug connector 131 is about to be inserted into or pulled out of the electronic device 12, and transmit the sensed first signal or the second signal to the first system through the first plug connector 131. After the first system receives the first signal, it will transmit the first signal to the docking station 11 through the connection line 13, so that the data processing module in the docking station 11 is started. Then, after the electronic device 12 is powered on, the first level signal pin 151 on the first connector 15 transmits a high-level signal to the second level signal pin 161 of the second connector 16 through the first channel. The second connector 16 transmits the high-level signal to the data processing module, and the data processing module powers on the data processing module through the high-level signal. After the docking station 11 is powered on, the first reset signal pin 152 on the first connector 15 of the electronic device 12 transmits a reset signal to the second reset signal pin 162 of the second connector 16 through the second channel. Thus, the second connector 16 sends the reset signal to the data processing module, and the data processing module initializes the data processing module through the reset signal. Then, the second clock signal pin 163 of the second connector 16 sends a clock request signal to the first clock signal pin 153 of the first connector 15 through the third channel. The first clock signal pin 153 of the first connector 15 sends a clock signal to the second clock signal pin 163 of the second connector 16 through the third channel according to the clock request signal. The second connector 16 sends the clock signal to the data processing module, and the data processing module performs identification and status synchronization through the clock signal. Then, the data processing module transmits a confirmation signal to the first connector, so that the electronic device successfully identifies the graphics card.

[0076] In this embodiment, after the electronic device 12 is powered off, the first system receives the second signal. At this time, it will transmit the second signal to the docking station 11 through the connection line 13 to unload the data processing module in the docking station 11. Then the electronic device 12 is powered off. At this time, the high level in the electronic device 12 becomes low level. The first level signal pin 151 on the first connector 15 transmits a low-level signal to the second level signal pin 161 of the second connector 16 through the first channel. After the second connector 16 receives the low-level signal, it will execute the power-off process of the docking station 11.

[0077] In an embodiment of the present application, before the electronic device 12 shuts down, the first system receives a second signal. At this time, the second signal will be transmitted to the docking station 11 through the connection line 13 to unload the data processing module in the docking station 11. The first reset signal pin 152 on the first connector 15 transmits the reset signal to the second reset signal pin 162 of the second connector 16 through the second channel. After receiving the reset signal, the second connector 16 will execute the sleep state of the docking station 11, and the user can pull out the first plug 131 from the electronic device 12. Thus, the synchronous power-on and power-off of the docking station 11 and the electronic device 12 are realized.

[0078] In this embodiment, the first plug 131 is of the Oculink interface type.
