DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0023] The expansion dock provided by the utility model is described in detail below in conjunction with the embodiments.

[0024] See also Figures 1 to 3 , Figure 1 It is a structural schematic diagram of an embodiment of the expansion dock of the present application; Figure 2 is a structural schematic diagram of another embodiment of the expansion dock of the present application; Figure 3 It is a schematic diagram of the working status of another embodiment of the expansion dock of the present application. The present application provides a expansion dock 100, and the expansion dock 100 includes a main controller 1 and at least two first interfaces 2. The main controller 1 is used to obtain a charging configuration signal input by a user. The main controller 1 can be a microcontroller unit (MCU) or the like. The charging configuration signal includes the power mode of each first interface 2. At least two first interfaces 2 are used to connect other access devices 200. The access device 200 can be a device for a mobile phone waiting to be charged. The access device 200 can be connected to the first interface 2 in a detachable and plug-in manner. The main controller 1 is coupled to the first interface 2. The main controller 1 is used to send a charging configuration signal to each first interface 2, and to control each first interface 2 to output a power mode corresponding to the charging configuration signal.

[0025] Specifically, when the user sets a charging configuration including information such as a power mode for a first interface 2, the main controller 1 configures the output power of the corresponding first interface 2 to the power mode according to the charging configuration. When the main controller 1 detects that the first interface 2 is connected to the access device 200, the main controller 1 controls the first interface 2 to power the access device 200 according to the power mode. The power modes of each first interface 2 can be the same or different. The sum of the power modes of each first interface 2 is less than or equal to the total power that the docking station 100 can provide to the access device 200.

[0026] The power mode of each first interface 2 can be a fixed value or a priority setting when allocating power. In a specific embodiment, the power mode of the first interface 2 is a fixed value. When a certain first interface 2 supplies power to the access device 200, regardless of whether other first interfaces 2 are connected to the access device 200, the first interface 2 only supplies power to the access device 200 according to the fixed value of the power mode. For example, the total power that the docking station 100 can provide to the access device 200 is 80W. The docking station 100 includes a first first interface and a second first interface. The user can set the power mode of the first first interface to 20W and the power mode of the second first interface to 40W. When the first first interface is connected to the access device 200, regardless of whether the second first interface is connected to the access device 200, the first first interface always maintains a maximum power mode of 20W to supply power to the access device 200. When the second first interface is also connected to the access device 200, the first first interface still supplies power to the access device 200 according to the maximum 20W. The second first interface supplies power to the access device 200 according to the maximum power mode of 40W.

[0027] In another specific embodiment, the power mode of the first interface 2 is a priority setting for allocating power. When only one first interface 2 is connected to the access device 200, the main controller 1 controls the first interface 2 to meet the power demand of the access device 200 as much as possible, and the maximum output power of the first interface 2 is the total power that the docking station 100 can provide for the access device 200. When there are at least two first interfaces 2 connected to the access device 200, the main controller 1 controls each first interface 2 to meet the power demand of each first interface 2 in turn according to the power allocation priority set in the corresponding power mode. When the priority of allocating power between the two first interfaces 2 is the same, the main controller 1 controls the two first interfaces 2 to equally divide the remaining power that the docking station 100 can provide for the access device 200. For example, the total power that the docking station 100 can provide for the access device 200 is 80W. The docking station 100 includes a first first interface and a second first interface. The user can set the power mode of the first first interface to a high priority and the power mode of the second first interface to a low priority. When the first first interface is connected to the access device 200, the first first interface supplies power to the access device 200 at a maximum power of 80W. When the second first interface is also connected to another access device 200, the second first interface uses the remaining power after deducting the power occupied by the first first interface from the total power that the expansion dock 100 can provide to the access device 200 as the maximum power to power the other access device 200. In addition, the user can also set the power mode of the first first interface to normal priority and the power mode of the second first interface to normal priority. When the first first interface is connected to the access device 200, the first first interface powers the access device 200 at a maximum power of 80W. When the second first interface is also connected to another access device 200, the first first interface powers the access device 200 at a maximum power of 40W, and the second first interface powers the other access device 200 at a maximum power of 40W.

[0028] Through the above settings, the user can set the charging power of each first interface 2 according to the needs and form a charging configuration signal. After the main controller 1 obtains the charging configuration signal, it can adjust the power of each first interface 2 accordingly. Therefore, the user can clearly understand the power distribution of each first interface 2 of the docking station 100, and can adjust the power distribution ratio according to his own preferences, making the docking station 100 easy to use.

[0029] The way in which the main controller 1 obtains the charging configuration signal can be set according to actual conditions. In a specific embodiment, the user inputs the charging configuration signal on the external control device 300. The external control device 300 is connected to the main controller 1 in communication and sends the charging configuration signal to the docking station 100. In another specific embodiment, the docking station 100 also includes an interactive component 9. The interactive component 9 is connected to the main controller 1. The interactive component 9 is used to interact with the user and form a charging configuration signal according to the user's input. The interactive component 9 can be a touch screen arranged on the surface of the docking station 100. The user inputs the required charging settings by interacting with the touch screen, and the interactive component 9 forms a charging configuration signal according to the charging settings input by the user. The interactive component 9 can also be a mechanical button arranged on the docking station 100. Different postures of the mechanical button correspond to different charging configuration signals. The user can change the posture of the mechanical button by toggling or pressing, and then input the required charging settings.

[0030] The specific manner in which the main controller 1 controls each first interface 2 to output a power mode corresponding to the charging configuration signal can be determined according to actual conditions. For example, in a specific embodiment, the main controller 1 can support the Power Delivery (PD) protocol. Based on the PD protocol, the main controller 1 can generate a power data object (PDO) that matches the power mode of each first interface 2, and send the PDO to the access device 200 through each first interface 2. After establishing a power supply protocol with the access device 200, each first interface 2 outputs a power mode to the access device 200. The above-mentioned main controller 1 sends a charging configuration signal to each first interface 2, and the method and content of controlling each first interface 2 to output a power mode corresponding to the charging configuration signal are conventional knowledge in the field and will not be further elaborated here.

[0031] The type of the first interface 2 can be Type-A, Type-B, Type-C, miniUSB, microUSB, etc. The types of different first interfaces 2 can be set to be different or the same. For example, half of the first interfaces 2 can be set to Type-C interfaces, and the other half of the first interfaces 2 can be set to Type-A interfaces. Such a setting is conducive to the expansion dock 100 to adapt to the interface type requirements of different access devices 200.

[0032] In one embodiment, the docking station 100 further includes a second interface 3. The second interface 3 is connected to the main controller 1. The second interface 3 is used to couple with an external control device 300 and receive a charging configuration signal from the external control device 300. The external control device 300 may be a laptop computer, a mobile phone, or other device.

[0033] Through the above settings, when the user inputs a charging configuration signal on the external control device 300, the charging configuration signal can be transmitted from the external control device 300 to the second interface 3 and then to the main controller 1, and the charging configuration signal transmission process is stable.

[0034] The specific way of coupling the external control device 300 with the second interface 3 can be direct connection or wireless connection. In one specific embodiment, the external control device 300 is detachably inserted into the second interface 3. The charging configuration signal is transmitted to the second interface 3 by means of a USB interface signal. In another specific embodiment, the external control device 300 establishes a wireless communication connection with the second interface 3. The charging configuration is transmitted to the second interface 3 by means of wireless communication.

[0035] See also Figure 2 In one embodiment, the docking station 100 further includes a sub-controller 4. The sub-controller 4 may be a PD controller supporting the PD protocol. The sub-controller 4 is connected to the main controller 1. The sub-controller 4 may communicate with the main controller 1 via an I2C bus. The sub-controller 4 is also connected to the first interface 2 and / or the second interface 3. The sub-controller 4 is used to allocate power to the corresponding connected interface.

[0036] Through the above settings, the function of controlling the power of each first interface 2 and / or second interface 3 can be implemented by the sub-controller 4, and the function of the expansion dock 100 is more modular and reasonably configured.

[0037] The sub-controller 4 may distribute the power of the corresponding connected interface by communicating with the main controller 1 to obtain the charging configuration information. The sub-controller 4 outputs the PDO to the access device 200 connected to the first interface 2 and / or the external control device 300 connected to the second interface 3 based on the charging configuration information, thereby adjusting the output power of the first interface 2 and / or the second interface 3. The sub-controller 4 may communicate with the access device 200 through CC1 / CC2, thereby obtaining the insertion status of the access device 200 and the positive and negative directions of the insertion.

[0038] The sub-controller 4 can be connected to the first interface 2 and / or the second interface 3 according to actual needs. In a specific embodiment, the sub-controller 4 is connected to the first interface 2. The first interface 2 supplies power to the access device 200. The sub-controller 4 adjusts the output power of each first interface 2 to a power mode according to the charging configuration signal. In another specific embodiment, the sub-controller 4 is connected to the second interface 3. The second interface 3 supplies power to the external control device 300. The sub-controller 4 adjusts the output power of the second interface 3 according to the charging configuration signal.

[0039] In another specific embodiment, the sub-controller 4 is respectively connected to the first interface 2 and the second interface 3. The first interface 2 is used to power the access device 200. The second interface 3 is used to obtain power from the external control device 300 and transmit the power to the first interface 2 to power the access device 200. The sub-controller 4 adjusts the output power of each first interface 2 to a power mode according to the charging configuration signal, and adjusts the input power of the second interface 3 according to the charging configuration signal.

[0040] In another specific embodiment, the sub-controller 4 is respectively connected to the first interface 2 and the second interface 3. The first interface 2 is powered by the access device 200. The second interface 3 is powered by the external control device. The sub-controller 4 adjusts the output power of each first interface 2 to a power mode according to the charging configuration signal, and adjusts the output power of the second interface 3 according to the charging configuration signal.

[0041] See also Figure 3 In one embodiment, the sub-controller 4 includes a first sub-controller 41 and a second sub-controller 42. The first sub-controller 41 is connected to each first interface 2. The main controller 1 sends a charging configuration signal to the first sub-controller 41. The main controller 1 controls each first interface 2 to output a power mode corresponding to the charging configuration signal through the first sub-controller 41. The second sub-controller 42 is connected to the second interface 3. The second sub-controller 42 is used to configure the output power of the second interface 3.

[0042] Specifically, both the first sub-controller 41 and the second sub-controller 42 can be PD controllers. When the first interface 2 is connected to the access device 200 and the second interface 3 is connected to the external control device 300, the first sub-controller 41 and the second sub-controller 42 can update their respective corresponding PDOs according to the charging configuration information. The first sub-controller 41 sends a PDO to the access device 200 through the first interface 2. After establishing a power supply protocol with the access device 200, the output power of each first interface 2 is controlled. The second sub-controller 42 sends a PDO to the external control device 300 through the second interface 3. After establishing a power supply protocol with the external control device 300, the output power of the second interface 3 is controlled.

[0043] Through the above settings, the power control of the first interface 2 and the second interface 3 are independently controlled by the first sub-controller 41 and the second sub-controller 42 respectively. The two can configure different parameters according to different access devices 200, are not likely to interfere with each other, and the performance of the expansion dock 100 is stable.

[0044] In one embodiment, the charging configuration signal includes a power allocation configuration signal, or a power allocation configuration signal and a charging protocol configuration signal. The power allocation configuration signal includes the power mode information of each first interface 2, and / or, includes the output power information of the second interface 3. The charging protocol configuration signal includes the default charging protocol information of each first interface 2, and / or, includes the default charging protocol information of the second interface 3. The sub-controller 4 is used to receive the power allocation configuration signal, and allocate the power of the first interface 2 and / or the second interface 3 according to the power allocation configuration signal. Alternatively, the sub-controller 4 is used to receive the power allocation configuration signal and the charging protocol configuration signal, allocate the power of the first interface 2 and / or the second interface 3 according to the power allocation configuration signal, and configure the default charging protocol of the first interface 2 and / or the second interface 3 according to the charging protocol configuration signal. The default charging protocol refers to the power supply protocol type that the sub-controller 4 first selects when communicating with the access device 200 when the access device 200 is connected to the first interface 2. And / or when the external control device is connected to the second interface 3, the power supply protocol type that the sub-controller 4 first selects when communicating with the external control device 300. The power supply protocol type can be QC (Quick Charge), PD fast charge, etc.

[0045] The charging configuration signal may include only a power allocation configuration signal, or may include both a power allocation configuration signal and a charging protocol configuration signal. When the sub-controller 4 is used to receive a power allocation configuration signal, the sub-controller 4 allocates power to the first interface 2 and / or the second interface 3 according to the power allocation configuration signal. When the sub-controller 4 is used to receive a charging protocol configuration signal, the sub-controller 4 configures the default charging protocol of the first interface 2 and / or the second interface 3 according to the charging protocol configuration signal. When the sub-controller 4 is used to receive a power allocation configuration signal and a charging protocol configuration signal, the sub-controller 4 allocates power to the first interface 2 and / or the second interface 3 according to the power allocation configuration signal, and configures the default charging protocol of the first interface 2 and / or the second interface 3 according to the charging protocol configuration signal.

[0046] Through the above settings, users can not only freely set the power allocation of each first interface 2 and / or second interface 3, but also freely configure the default charging protocol of each first interface 2 and / or second interface 3, which is more convenient for users to configure the charging method of the device according to their needs and is easy to use. In addition, compared with repeatedly trying to propose a protocol handshake with the access device 200 through the sub-controller 4, setting a default charging protocol is also conducive to reducing the process of repeated attempts to handshake by the device, so that the sub-controller 4 can establish a power supply protocol with the access device 200 faster, and the expansion dock 100 has better performance.

[0047] The sub-controller 4 configures the default charging protocol of the first interface 2 and / or the second interface 3 by updating the configuration information including the default charging protocol in the PDO together with the power allocation configuration information. When the sub-controller 4 communicates with the access device 200 and / or the external control device 300 through the PDO, the default charging protocol can be sent to the access device 200 and / or the external control device 300, and then the power supply protocol is established by handshaking in accordance with the default charging protocol.

[0048] See also Figure 4 , Figure 4 FIG. 1 is a schematic diagram of the structure of another embodiment of the expansion dock of the present application. Figures 1 to 3 In one embodiment, the sub-controller 4 includes a protocol identification circuit 43 and a control circuit 44 coupled to each other. The protocol identification circuit 43 is also used to connect to the sub-controller 4. The control circuit 44 is also connected to the first interface 2 and / or the second interface 3. The protocol identification circuit 43 is used to detect the identification signal sent by the sub-controller 4 and send the identification signal to the control circuit 44. Among them, the identification signal is used to characterize the protocol type of the access device 200 communication. The control circuit 44 is used to send a control signal to the sub-controller 4 to trigger the sub-controller 4 to configure a charging mode matching the protocol type.

[0049] Specifically, when the sub-controller 4 fails to handshake with the access device 200 through the default charging protocol, it means that the access device 200 may not support the establishment of a power supply protocol according to the default charging protocol. At this time, the sub-controller 4 can identify the supported protocol type fed back by the access device 200 through the identification circuit 43, and notify the control circuit 44 of the result. The control circuit 44 adjusts the state of the sub-controller 4 to match the identified protocol type, and establishes a power supply protocol with the access device 200. The specific implementation method of the above-mentioned identification circuit 43 identifying the protocol type of the access device 200 communication and the control circuit 44 adjusting the charging mode of the sub-controller 4 to match the protocol type is conventional knowledge in the art and will not be repeated here.

[0050] Through the above settings, the failure of the sub-controller 4 to handshake with the access device 200 through the default charging protocol will not cause the access device 200 to fail to charge. The sub-controller 4 can promptly re-identify the charging protocol supported by the access device 200 and re-establish the power supply connection with it, and the expansion dock 100 is stable to use.

[0051] In one embodiment, the second interface 3 includes a charging terminal 31. The charging terminal 31 may be integrated into the second interface 3. The charging terminal 31 is used to input power to the external control device 300 when the docking station 100 is connected to an external power source. Alternatively, the charging terminal 31 is used to charge the access device 200 through the external control device 300 when the docking station 100 is not connected to an external power source.

[0052] Through the above settings, when the docking station 100 is connected to an external power source, the docking station 100 can supply power to the external control device 300 through the charging terminal 31, that is, the docking station 100 can replace the power adapter of the external control device 300. When the docking station 100 is not connected to an external power source, the docking station 100 can use the external control device 300 as a power source to charge the access device 200 through the charging terminal 31. Regardless of whether the docking station 100 is connected to an external power source, the docking station 100 can supply power to the access device 200, which is convenient to use.

[0053] In one embodiment, the docking station 100 further includes a power supply circuit 5. The power supply circuit 5 is used to connect to an external power source so as to charge the access device 200 according to the charging configuration signal through the docking station 100. Thus, the docking station 100 can power both the access device 200 and the external control device 300, which is convenient to use.

[0054] Further, the docking station 100 also includes a second power conversion circuit 7 and at least two first power conversion circuits 6. Both the first power conversion circuit 6 and the second power conversion circuit 7 can be set as DC-DC conversion circuits. Each first interface 2 is electrically connected to the power supply circuit 5 through a corresponding first power conversion circuit 6. The second interface 3 is electrically connected to the power supply circuit 5 through the second power conversion circuit 7. The first power conversion circuit 6 converts the input power of the power supply circuit 5 and outputs it to each first interface 2. The second power conversion circuit 7 converts the input power of the power supply circuit 5 and outputs it to the second interface 3. Among them, the main controller 1 is connected to the first power conversion circuit 6 and the second power conversion circuit 7 respectively. The sub-controller 4 is used to control the output power of the first power conversion circuit 6 and the second power conversion circuit 7 respectively. The main controller 1 can be directly connected to the first power conversion circuit 6 and the second power conversion circuit 7 respectively, or it can be indirectly connected to the first power conversion circuit 6 and the second power conversion circuit 7 through the sub-controller 4. In a specific embodiment, the main controller 1 is connected to the sub-controller 4. The sub-controller 4 is connected to the first power conversion circuit 6 and the second power conversion circuit 7 respectively. The main controller 1 sends a control signal to the first power conversion circuit 6 and the second power conversion circuit 7 through the sub-controller 4 to control the power output by the first power conversion circuit 6 and the second power conversion circuit 7, thereby controlling the power of each of the first interface 2 and the second interface 3. The specific implementation method of the above-mentioned sub-controller 4 controlling the first power conversion circuit 6 and the second power conversion circuit 7 is conventional knowledge in the art and will not be repeated here.

[0055] Through the above settings, the sub-controller 4 can control the output power of the first interface 2 and the second interface 3 by controlling the first power conversion circuit 6 and the second power conversion circuit 7. The output power can be adjusted conveniently and the expansion dock 100 has a simple structure.

[0056] In one embodiment, the docking station 100 further includes a temperature detection circuit 8. The temperature detection circuit 8 is connected to the main controller 1. The temperature detection circuit 8 may include a temperature sensor. The temperature detection circuit 8 is used to detect the temperature inside the docking station. The main controller 1 may obtain the detection result of the temperature detection circuit 8. The main controller 1 is also used to trigger the first interface 2 to reduce the charging power in response to the temperature inside the docking station being higher than a threshold.
