DETAILED DESCRIPTION

[0025] Exemplary embodiments of the present application will be described in detail with reference to the drawings. Although exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that this application will be thorough and complete, and will fully convey the scope of the application to those skilled in the art.

[0026] It should be noted that, unless otherwise specified, technical or scientific terms used in the present application should be understood as their common meanings to those skilled in the art to which the present application pertains.

[0027] Embodiment 1

[0028] The present application provides an adapter, as shown in Figures 1 to 8 The adapter comprises at least one first interface 1 for connecting to a power supply, at least two second interfaces 2, one second interface 2 for connecting one electronic device, the first interface 1 being connected to the two second interfaces 2 respectively, a communication connection module 3 connected to the two second interfaces 2 respectively, and the communication link between the two second interfaces 2 being able to be connected or disconnected through the communication connection module 3.

[0029] The first interface 1 can be directly connected to a power supply to provide power input for the entire adapter, or connected to a converted DC power supply, or connected to a proprietary power adapter provided by an early notebook computer, which is an AC-DC adapter and can achieve resource utilization. The second interface 2 can be a universal Type-C interface to ensure physical connection with various electronic devices such as mobile phones, tablets, wireless earphones, etc. The adapter includes at least two second interfaces 2, each of which corresponds to connection of an electronic device. For example, one second interface 2 can be connected to a mobile phone, and the other second interface 2 can be connected to an electronic device such as a tablet computer. The first interface 1 can be electrically connected to the two (or more) second interfaces 2 through internal circuit wiring or a circuit board design, so that the power input from the first interface 1 can be transmitted to each connected electronic device.

[0030] The communication connection module 3 can be composed of a signal switching chip and a controller. The signal switching chip is responsible for connecting or disconnecting the communication link between the two second interfaces 2, and the controller (such as a microcontroller) is responsible for controlling the state of the signal switching chip. When it is necessary to connect the communication link between the two second interfaces 2, the controller sends a control signal to the signal switching chip according to external input (such as the user pressing the button on the adapter or through wireless control), and the signal switching chip connects the communication line between the two second interfaces 2, which can realize the transmission of, for example, USB high-speed signals between the two second interfaces 2.

[0031] Specifically, when data transmission is needed between a mobile phone and a tablet computer, for example, there are some files on the mobile phone to be transmitted to the tablet computer. The user can operate the control button (connected to the communication connection module 3) on the adapter, or send an instruction to the communication connection module 3 through the matching application installed on the mobile phone and the tablet computer. After receiving the instruction, the communication connection module 3 establishes a data communication link between the two second interfaces 2, so that data transmission can be performed between the mobile phone and the tablet computer.

[0032] The adapter provided by the embodiment of the present application realizes that multiple electronic devices can be charged simultaneously on one adapter by setting at least one first interface 1 to access a power supply and multiple second interfaces 2 to connect different electronic devices, which facilitates the user to supplement the power of multiple electronic devices at the same place, without the need to use multiple independent chargers, and reduces the number of connections between devices and the occupied space. Through the function of the communication connection module 3 that can connect or disconnect the communication link between the two second interfaces 2, additional data transmission ports are avoided, and the cable is simplified. The adapter provided by the embodiment of the present application enables the user to simultaneously realize the charging and data transmission functions on one charging device, which improves the use convenience and multifunctionality of the device.

[0033] In some embodiments, as shown in Figure 1 The second interfaces 2 are three, and the communication connection module 3 is connected with the three second interfaces 2 respectively; the communication connection module 3 can select two second interfaces 2 and control one of them to be connected or disconnected with the third second interface 2, or control the connection or disconnection of the communication link between any two second interfaces 2.

[0034] The three second interfaces 2 are all general Type-C interfaces, which can be conveniently connected with various electronic devices. Each Type-C interface corresponds to a Type-C protocol chip 5, so as to have complete data transmission lines and pins, and can simultaneously process power transmission and data transmission functions.

[0035] The data connection between the three second interfaces 2 can have various forms. For example, the three second interfaces 2 are marked as second interface A, second interface B and second interface C respectively. Through the communication connection module 3, two second interfaces 2 can be selected and one of them can be controlled to be connected or disconnected with the third second interface 2, so as to connect the second interface A with the second interface C, or connect the second interface B with the second interface C. Or through the communication connection module 3, the connection or disconnection of the communication link between any two second interfaces 2 can be controlled, so as to connect the second interface A with the second interface B, connect the second interface B with the second interface C, or connect the second interface A with the second interface C.

[0036] The adapter provided by the embodiments of the present application can meet different connection requirements between various devices. For example, in a mobile office scene, a user can connect a mobile phone, a tablet computer and a mobile hard disk to the adapter. The user can conveniently switch the data transmission link between different devices, for example, quickly transmit files in the mobile phone to the mobile hard disk, or extract files from the mobile hard disk to the tablet computer for viewing and editing, without frequently plugging and unplugging devices or changing data lines. Compared with using multiple separate data lines and adapter devices, the adapter provided by the embodiments of the present application reduces the number of physical cables required and the use of external adapter devices.

[0037] In some embodiments, the adapter further comprises a power distribution module 4, which is arranged close to the first interface 1 and is connected with the first interface 1 and the second interface 2 respectively; the power distribution module 4 can match the power of the power supply connected with the first interface 1 to the power of the electronic device connected with the second interface 2.

[0038] If the power supply or the power supply adapter connected with the first interface 1 has a high power, for example, a special power adapter equipped in an early notebook computer, which often has a power of 180W or even 300W, this may cause an overvoltage or overcurrent situation when the electronic device connected with the second interface 2 has a low power, thereby causing an overload of the internal circuit of the electronic device and damaging the electronic device.

[0039] To solve the above problems, the converter provided by the embodiment of the application is provided with a power distribution module 4, which is arranged close to the first interface 1 so as to better receive the power input from the first interface 1 and is connected to the second interface 2 through internal circuit wiring or PCB wiring.

[0040] When the electronic device accesses the second interface 2, the power distribution module 4 will first obtain the power requirement of the electronic device. For example, the power requirement information of the electronic device connected through the Type-C protocol chip 5 connected with the Type-C interface is obtained at the time of connection, and the power distribution module 4 receives the information through the data transmission line of the second interface 2. Once the power requirement of the electronic device accessed through the second interface 2 is determined, the power distribution module 4 will distribute the input power of the first interface 1.

[0041] If the input power of the first interface 1 is sufficient to meet the power requirements of all the accessed electronic devices, the power distribution module 4 will distribute the corresponding power to each second interface 2 to ensure that each electronic device can obtain the required power. If the input power of the first interface 1 is insufficient to meet the power requirements of all the electronic devices, the power distribution module 4 can distribute the power according to preset priority rules. These priority rules can be set by the user or determined according to the type of the electronic device.

[0042] The user-settable priority can set the priority of the electronic device through the matching application program or the physical button of the adapter, and the electronic device with high priority will be given priority to sufficient power, while the electronic device with low priority may obtain less power. The priority of the electronic device type can ensure the normal power requirement of the high-power device (such as a notebook computer), and for the low-power device (such as a wireless earphone), the power supply can be appropriately reduced, but the basic function can be ensured to operate.

[0043] Alternatively, the power distribution module 4 can dynamically adjust the power distribution according to the actual situation. For example, when an electronic device is unplugged from the second interface 2, the power distribution module 4 will redistribute the power to meet the power requirement of other electronic devices.

[0044] The converter provided by the embodiment of the application can use the special power adapter of the old notebook computer, and can be compatible with electronic devices with different power requirements under the condition of realizing resource utilization. Whether it is connected with a low-power wireless earphone (which may only need a few watts of power) or a high-power notebook computer (which may need dozens of watts or even hundreds of watts of power), the adapter can reasonably distribute the power according to the power requirement, avoid the problem that the electronic device cannot be normally charged or damaged due to power mismatch, and avoid the waste of power due to unreasonable power distribution.

[0045] In some embodiments, as shown in Figure 2 The power distribution module 4 includes a control unit 401 and a power detection unit 402 connected to each other. The power detection unit 402 is configured to detect the power of the power supply connected to the first interface 1 and the power of the power supply connected to the first interface 1. The control unit 401 matches the power of the power supply connected to the first interface 1 to each second interface 2 according to the detection information of the power detection unit 402.

[0046] The power detection unit 402 can use an integrated power sensor chip, such as INA226, etc. The chip can accurately measure the voltage and current by being connected to the power supply line of the first interface 1. The power detection unit 402 can have a dedicated voltage measurement pin and a current measurement pin, which are connected to the power supply line and the ground line of the first interface 1.

[0047] The control unit 401 can use a separate microcontroller (MCU), such as a common ARM Cortex-M series microcontroller, or as shown in Figure 3 The control unit 401 is connected to the power detection unit 402 and the second interface 2 through internal communication lines. The control unit 401 stores the power characteristics information of the devices connected to each second interface 2. The information can be pre-set or obtained through the communication protocol chip 5 of the second interface 2 when the device is connected.

[0048] The control unit 401 performs power matching operation according to the power information of the power supply connected to the first interface 1 fed back by the power detection unit 402 and the known power demand information of the devices connected to the second interface 2. For example, when a power supply is connected, the power detection unit 402 can detect the power of the power adapter connected to the first interface 1, the control unit 401 records the power and presets the maximum output power. When an electronic device is connected to the second interface 2, the Type-C protocol chip 5 connected to the second interface 2 learns the acceptable power of the electronic device, the distribution voltage and the power, and notifies the control unit 401 of the results. The control unit 401 calculates the remaining power and communicates and distributes power to other second interfaces 2 based on the remaining power.

[0049] The adapter provided by the embodiment of the application can intelligently and dynamically distribute power to each second interface 2 according to the actual connected power supply power and the power demand of the electronic device by setting the power distribution module 4, which includes a control unit 401 and a power detection unit 402 connected to each other, and ensures that the electronic device obtains appropriate power supply.

[0050] In some embodiments, as shown in Figure 2 and Figure 3 The power distribution module 4 further comprises a switch unit 403, which is connected to the control unit 401 and the power detection unit 402, respectively, and is used to control the connection or disconnection of the electrical signal between the first interface 1 and the power detection unit 402.

[0051] The switch unit 403 can be a high-performance power switching device, such as a MOSFET (Metal Oxide Semiconductor Field Effect Transistor) or an IGBT (Insulated Gate Bipolar Transistor). The switch unit 403 is connected to the control unit 401 and the power detection unit 402. Specifically, the output pin of the control unit 401 is connected to the control terminal (for MOSFET, it can be the gate; for IGBT, it can be the gate) of the switch unit 403, and the input and output terminals of the switch unit 403 are connected to the first interface 1 and the power detection unit 402, respectively. The control terminal of the switch unit 403 can be connected to a drive circuit, which can generate sufficient voltage and current to drive the on and off operations of the switching device according to the logic level signal of the control unit 401.

[0052] When power detection is needed, the control unit 401 ensures that the switch unit 403 is in the on state, so that the power detection unit 402 can accurately measure the power of the power supply connected to the first interface 1. When an abnormal situation is detected, such as overcurrent, overvoltage, or failure of the power detection unit 402, the control unit 401 will make the switch unit 403 off, cutting off the electrical signal connection between the first interface 1 and the power detection unit 402. For example, when the power detection unit 402 detects that the input current of the first interface 1 exceeds the set threshold, it will send a signal to the control unit 401, and the control unit 401 will immediately send an off signal to the switch unit 403 after receiving the signal, disconnecting the switch unit 403 and protecting the subsequent circuit from high current damage.

[0053] By setting the switch unit 403, the damage of overcurrent and overvoltage to the power detection unit 402 and the subsequent circuit can be prevented. When an abnormally large current or voltage occurs, the switch unit 403 can quickly disconnect, playing a protective role.

[0054] In some embodiments, as shown in Figure 4 and Figure 5 The adapter further comprises a housing 7, which has a containing space inside, and the communication connection module 3 and the power distribution module 4 are arranged in the containing space; the first interface 1 and the second interface 2 are arranged on the housing 7, and the first interface 1 and the second interface 2 are respectively located on different sides of the housing 7.

[0055] The shell 7 can be a cuboid structure with an accommodation space inside. The communication connection module 3 and the power distribution module 4 as well as some connection circuits can be installed on a circuit board, which is fixed to the inner wall of the shell 7 through support columns or guide rails.

[0056] The first interface 1 can be arranged on the side of the shell 7, facilitating the connection of a power adapter or a wall power socket. The second interface 2 can be arranged on the side of the shell 7 opposite to the first interface 1, and a plurality of second interfaces 2 can be arranged in an array, facilitating the user to plug and unplug different electronic devices. By arranging the first interface 1 and the second interface 2 on different sides of the shell 7, the rationality of wiring can be improved. The connection of the first interface 1 and the second interface 2 with the internal modules can be realized through internal wires or PCB traces.

[0057] The shell 7 provides physical protection for the internal communication connection module 3 and the power distribution module 4, preventing them from being affected by external physical impact, dust, moisture and other factors, and ensuring the normal work of the modules. The adapter becomes an integrated device, integrating various functional modules and interfaces, which can be conveniently carried and used by the user, avoiding the inconvenience caused by multiple dispersed components.

[0058] In some embodiments, as shown in Figure 4 and Figure 5 , the shell 7 further comprises a switch assembly 701 connected with the communication connection module 3. The switch assembly 701 has at least two states relative to the shell 7. The switch assembly 701 controls the communication connection module 3 to realize the connection or disconnection of the communication link between at least two second interfaces 2 through different states.

[0059] The switch assembly 701 can be a mechanical switch, such as a toggle switch or a button switch. The toggle switch can realize different switch states at different positions, and the button switch can distinguish different states through the number of presses or the length of press. For the mechanical switch, the shell of the switch can be made of plastic or metal, and there are mechanical structures such as contacts and springs inside to realize the on-off function of the switch.

[0060] The switch assembly 701 can be connected with the communication connection module 3 through wires. On the internal circuit board of the adapter, the pins of the switch assembly 701 will be welded to the circuit nodes of the control unit 401 or the control logic circuit 501 of the Type-C protocol chip 5, which will be connected to the control input port of the communication connection module 3.

[0061] When the switch assembly 701 is in the first state, such as the "ON" position of the toggle switch or the first press state of the push-button switch, it sends a high-level signal (or a low-level signal) to the communication connection module 3. Upon receiving this signal, the communication connection module 3 establishes the communication link between at least two of the second interfaces 2. When the switch assembly 701 is in the second state, such as the "OFF" position of the toggle switch or the second press state of the push-button switch, it sends the opposite level signal to the communication connection module 3. Upon receiving this signal, the communication connection module 3 disconnects the communication link between at least two of the second interfaces 2.

[0062] If there are three or more second interfaces 2, a multi-position rotary switch with multiple positions can be used, each corresponding to a different communication link connection state. For example, a rotary switch with three positions can represent the communication link state between different combinations of second interfaces 2. Alternatively, multiple push-button switches can be used, with different button combinations or button pressing sequences controlling different communication links. For instance, using three push-button switches labeled A, B, and C, pressing buttons A and B controls the communication link between second interface A and second interface B; pressing buttons B and C controls the communication link between second interface B and second interface C; and pressing buttons A and C controls the communication link between second interface A and second interface C.

[0063] By setting up the switch component 701, users can easily control the connection and disconnection of the communication link between at least two second interfaces 2 through simple operation of the switch component 701, without the need for complex software operation or the intervention of external devices.

[0064] In some embodiments, such as Figures 1 to 3 As shown, the adapter also includes a power conversion module 6, with one power conversion module 6 provided between each first interface 1 and second interface 2; the power conversion module 6 is an AC to DC conversion module or a DC to DC conversion module.

[0065] The power conversion module 6 is located between the first interface 1 and the second interface 2. The power conversion module 6 is connected to the protocol chip 5. When a power source is connected and a load is connected to the second interface 2, the protocol chip 5 learns the acceptable voltage of the load. The control unit 401 distributes the voltage to the second interface 2 through the power conversion module 6, thereby changing the form of electrical energy (such as AC to DC) or adjusting the amplitude of DC voltage, etc.

[0066] If the first interface 1 is connected to an AC-DC adapter, an AC-to-DC conversion module needs to be set between the first interface 1 and the second interface 2. One end of the AC-to-DC conversion module is connected to the first interface 1 to receive AC power input, and the other end is connected to the second interface 2. The AC-to-DC conversion module converts AC power into DC power to output stable DC voltage for powering the electronic device. For example, when the first interface 1 is connected to an AC-DC adapter, the module converts the AC power into 5V, 9V, or 12V DC voltage to meet the charging requirements of different electronic devices.

[0067] If the first interface 1 is connected to a DC-DC adapter, a DC-to-DC conversion module needs to be connected between the first interface 1 and the second interface 2. When the DC voltage input by the first interface 1 does not match the voltage required by the electronic device connected to the second interface 2, the DC-to-DC conversion module comes into play. For example, when the first interface 1 inputs 12V DC voltage and the electronic device requires 5V DC power, the DC-to-DC conversion module reduces the 12V voltage to 5V and outputs it to the second interface 2.

[0068] By setting the AC-to-DC conversion module or the DC-to-DC conversion module, the converter can adapt to electronic devices with different power requirements. Whether the device requires AC power conversion to a specific DC voltage or adjustment of the input DC voltage, the adapter can meet the power requirements of the device through the corresponding conversion module.

[0069] In some embodiments, as shown in FIG. 1, the first interface 1 is a plurality of first interfaces 1, and the plurality of first interfaces 1 have different shapes. Figure 4

[0070] The first interface 1 can be circular, square, flat, or other shapes corresponding to different power adapters or power interfaces. These different shapes of the first interface 1 are reasonably distributed on the shell of the adapter, and each first interface 1 is connected to an independent circuit path, so that multiple types of power adapters can be connected, improving the versatility of the adapter.

[0071] The converter of the embodiments of the present application has at least one first interface 1 for connecting to a power source and at least two second interfaces 2 for connecting to electronic devices, and can simultaneously charge multiple electronic devices. The communication connection module 3 can flexibly connect or disconnect the communication link between the two second interfaces 2 to meet the data transmission requirements between devices. The power distribution module 4 reasonably matches the power of the first interface 1 according to the power requirements of the devices, and can be compatible with different power devices, avoiding problems caused by power mismatch and optimizing power utilization.

[0072] Embodiment 2

[0073] ​The adapter provided in Embodiment 2 is different from the adapter provided in Embodiment 1 in that the manner of matching power for each second interface 2 is different.

[0074] In some embodiments, as shown in Figure 8 Each gear adjustment assembly 702 is connected with the power distribution module 4, and the gear adjustment assembly 702 has multiple position states, and each position state corresponds to a preset power output value in the power distribution module 4.

[0075] The gear adjustment assembly 702 can be a rotary gear adjustment knob, which usually has multiple gears and can be manually rotated by the user to switch different position states. The outer part of the knob is exposed outside the shell 7 for the user to operate, and the inner part is connected with the circuit inside the adapter through a mechanical structure. A sliding gear adjustment bar can also be used, and the user can change the position state by sliding the adjustment bar. The sliding adjustment bar usually has clear gear marks to help the user identify different positions.

[0076] For the rotary gear adjustment knob, there are conductive springs or pins inside, which will be in contact with different circuit nodes with the rotation of the knob, sending corresponding electrical level signals to the power distribution module 4. For the sliding gear adjustment bar, there is a sliding contact inside, which will connect different wires when in different positions, transmitting different signals to the power distribution module 4. Different wires in different positions are connected to different input pins of the switch unit 403, thereby realizing the selection of different preset power output values.

[0077] The power distribution module 4 internally stores multiple preset power output values, which can be stored in the storage unit of the microcontroller (MCU) in the control unit 401 in the power distribution module 4; or using the control logic circuit 501 in the Type-C protocol chip 5. As shown in Figure 6 The gear adjustment assembly 702 can be connected with the control unit 401 in the power distribution module 4, or as shown in Figure 7 The power distribution module 4 can store three preset power output values, which are 5W, 10W and 15W, corresponding to the three gears of the gear adjustment assembly 702.

[0078] When the user operates the gear adjustment assembly 702 and switches it to a certain position state, the signal corresponding to the state is transmitted to the power distribution module 4 through the connected circuit. After the control unit 401 (such as MCU) in the power distribution module 4 receives the signal, it will identify the corresponding preset power output value. For example, when the power supply is connected, according to the rated power of the power adapter, the gear power of the gear adjustment assembly 702 is set, and the sum of the maximum output powers of each second interface 2 cannot be obviously greater than the rated power of the power adapter; when the second interface 2 has an electronic device connected, the control unit 401 or the protocol chip 5 distributes voltage and power that does not exceed the set value.

[0079] By setting the gear adjustment assembly 702, the user can flexibly adjust the power output of each second interface 2 according to the needs of different devices through the gear adjustment assembly 702. Thus, the user can manually select the appropriate power gear according to the specific situation of the device to ensure that the device can work in the best power state. For example, in a home use scenario, when a mobile phone is connected to the second interface 2, the user can adjust the gear adjustment assembly 702 to the power gear suitable for charging the mobile phone to achieve fast charging or ordinary charging; when a low-power Bluetooth headset is connected, the gear can be adjusted to a low-power gear to avoid overcharging and waste energy.

[0080] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of changes or replacements within the technical scope disclosed in the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
