Description

Technical Field

[0001] This application relates to the technical field of electronic devices, and in particular, to an electronic device. Background Art

[0002] Nowadays, for computers, the number of external devices that need to be used in cooperation is increasing continuously. More external interfaces need to be set on the computer. The power supply capacity of the computer is limited. If more power is allocated to the external interfaces, the power at the CPU end will be reduced and cannot meet the core performance requirements, seriously affecting the user experience.

[0003] Therefore, the designer designs that the total amount of power that all external interfaces can utilize is limited to ensure the requirements of the CPU. At the same time, current limiting is performed on the external interfaces in advance. Regardless of the number of external interfaces, the current upper limit of each external interface is restricted, and the limit amounts of multiple external interfaces decrease gradually.

[0004] However, for an external interface with a small current limit amount, if the rated current required by the external device to be matched is higher than this limit amount, even if the current value that the computer can supply to this interface can meet the requirements of the external device, this external interface is restricted by current limiting and cannot provide enough current. Then the external device will not be recognized and cannot cooperate with the computer, seriously affecting the user experience. Summary of the Utility Model

[0036] It should be noted that unless otherwise specified, the technical terms or scientific terms used in this application should have the ordinary meanings understood by those skilled in the art to which this application belongs.

[0037] The technical solution of the embodiment of this application is to solve the above technical problems, and the general idea is as follows:

[0038] Embodiment 1

[0039] Refer to the attached Figure 1 and the attached Figure 2 As shown in the figure, the electronic device provided in this embodiment includes a power supply component 1, a plurality of electrical connection ports 2, a plurality of first temperature sensors 3, and a controller 4; the plurality of electrical connection ports 2 are connected in parallel to the power supply component 1, and the electrical connection ports 2 are used to electrically connect external electronic devices (not shown in the figure); the plurality of first temperature sensors 3 are arranged in one-to-one correspondence with the plurality of electrical connection ports 2 to obtain the conduction temperature of the electrical connection ports 2; the controller 4 is signal-connected to the plurality of first temperature sensors 3, the plurality of electrical connection ports 2, and the power supply component 1, so as to be able to determine the conduction current of at least one conducted electrical connection port 2 according to the conduction temperature of the electrical connection port 2, and determine and adjust the remaining conduction current of other electrical connection ports 2 according to the conduction current of the electrical connection port 2 and the total available conduction current provided by the power supply component 1.

[0040] It can be understood that in order to solve the problem that the power supply situation of the electrical connection port does not match the actual needs, the electronic device provided in this embodiment realizes the purpose of obtaining the actual conduction current through temperature at low cost by arranging the first temperature sensors 3 in one-to-one correspondence with the electrical connection ports 2, so as to adjust the remaining adjustable current according to the conduction current of the conducted electrical connection port 2, thereby dynamically adjusting the conduction current of other electrical connection ports 2, improving the flexibility of power supply adjustment, and ensuring that there is no waste or redundancy of excess power during the conduction process of the electrical connection port 2.

[0041] Among them, the electronic device provided in this embodiment can be, but is not limited to, a host device, a laptop computer, or other terminal electronic devices that can externally connect to external electronic devices. The electrical connection port 2 can be, but is not limited to, a USB interface, such as: USB Type-A, USB Type-B, USB Type-C, USB mini, USB Micro, and so on.

[0042] Among them, the power supply component 1 is a power supply device within the electronic device, capable of supplying power to the electrical connection port 2, the first temperature sensor 3, the controller 4, and even other electrical components within the electronic device. The power supply component 1 can be a storage type or a plug-in type, such as nickel-cadmium batteries, nickel-metal hydride batteries, lithium-ion batteries (including both liquid and polymer types), and lithium iron phosphate batteries. In this embodiment, the power supply component 1 is electrically connected to the electrical connection port 2 through wiring so that several electrical connection ports 2 are connected in parallel to be able to independently supply power to the electrical connection port 2. For example, it can be connected by splitting lines through a hub. This setting method can be easily understood by those skilled in the art and will not be elaborated here.

[0043] Among them, the first temperature sensor 3 can perform temperature detection, and can be, but is not limited to, a resistance temperature detector, a thermistor, or a semiconductor temperature sensor. In this embodiment, the first temperature sensor 3 is provided in one-to-one correspondence with the electrical connection port 2, specifically on the wiring between the electrical connection port 2 and the power supply component 1, and can be, but is not limited to, one end of the wiring close to the hub, so as to be able to detect the temperature in a timely and accurate manner. In actual operation, the external electronic device connected to the electrical connection port 2 does not work at the rated current throughout the process. It may be able to work normally by drawing less current. Then, at this time, the first temperature sensor 3 can be used to detect the temperature to determine how much current the external electronic device actually draws, that is, the conduction current.

[0044] Among them, the controller 4 is a PLC controller capable of data transceiver, analysis and comparison, calculation and processing, and even program editing. In this embodiment, the controller 4 can be, but is not limited to, including an embedded controller (EC) and a proportional-derivative controller (PD). The EC is used to execute a control system that formulates independent control functions and has the ability to process data in a complex manner. The PD adjusts by comparing the error between the actual value and the target value and uses the PD algorithm to achieve the purpose of system stability. In this embodiment, the EC is electrically connected to the PD, and the EC is electrically connected to the power supply component 1, and can obtain the total conduction current, conduction voltage (such as 5V), total conduction power, etc., and send a current distribution strategy to the PD. The PD is electrically connected to the electrical connection port 2 and supplies power to the corresponding electrical connection port 2 according to the current distribution strategy of the EC. In this embodiment, the EC is electrically connected to the first temperature sensor 3 to obtain temperature data for obtaining the conduction current of the corresponding electrical connection port 2.

[0045] When an external electronic device is connected to the electronic device through the electrical connection port 2, a handshake protocol communication is first carried out. The external electronic device will send the rated voltage, rated current, rated power, etc. required by itself to the electronic device. For different external electronic devices, they may have a rated current range. For example, a power bank can conduct within the current supply range between the minimum rated current and the maximum rated current. In this embodiment, the controller 4 determines and adjusts the remaining conduction current of other electrical connection ports 2 according to the conduction current of the conducted electrical connection port 2 and the total conduction current of the power supply component 1. Specifically, it can be for other unconducted electrical connection ports 2 or for other already conducted electrical connection ports 2. For example: it can be to adjust the remaining conduction current that can be allocated to the unconducted electrical connection port 2 in real time according to the conduction current of the conducted electrical connection port 2, or it can be to adjust the magnitude of the conduction current of other already conducted electrical connection ports 2 in real time according to the conduction current of one or some conducted electrical connection ports 2.

[0046] For example: when there are two electrical connection ports 2, one of the electrical connection ports 2 is turned on. After the external electronic device connected thereto shakes hands with the electronic device, the EC and PD cooperate to provide it with a current corresponding to its rated current to turn it on. Then, the controller 4 can determine the conduction current according to the temperature of the electrical connection port 2. If the conduction current is less than the rated current, the excess current is divided and the remaining available conduction current is distributed to the other non-conducted electrical connection port 2 for real-time detection and real-time distribution; when another non-conducted electrical connection port 2 connects to an external electronic device later, if it is determined during the handshake process that the remaining available conduction current is less than its rated current, then the electronic device will not recognize the external electronic device, and the two are not connected and cannot perform data interaction. When the temperature and conduction current are detected next time, if the remaining available conduction current that can be distributed meets its rated current, the recognition is successful; and so on, for the form of multiple electrical connection ports 2, dynamic adjustment is performed.

[0047] For example: at least two of the electrical connection ports 2 are simultaneously connected to an external electronic device, and the controller 4 adjusts the conduction current of the other electrical connection ports 2 to the minimum or maximum conduction current of the external electronic device according to the conduction current of any one of the turned-on electrical connection ports 2.

[0048] It can be understood that: when there are two electrical connection ports 2 and both are in the on state, the first electrical connection port 2 starts to conduct with the rated current, and the second electrical connection port 2 conducts corresponding to the lowest rated current. When the conduction current of the first electrical connection port 2 is detected to be less than its rated current later, the controller 4 will distribute the excess current to the second electrical connection port 2 so that it can reach a higher or the highest rated current, and so on, for the form of multiple electrical connection ports 2, dynamic adjustment is performed.

[0049] According to the above, for the electronic device provided in this embodiment, for multiple electrical connection ports 2, the conduction current is determined by temperature detection, and the available conduction current of the other electrical connection ports 2 is adjusted according to the conduction current of the turned-on electrical connection port 2, so as to reasonably allocate power supply; thus, the problem that the power supply situation of the electrical connection port does not match the actual needs is solved.

[0050] In this article, the term "and / or" is merely a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B is specifically understood as: it can include both A and B at the same time, A can exist alone, or B can exist alone, and any one of the above three situations can be satisfied.

[0051] Further, referring to the appendix Figure 2, in the electronic device provided in this embodiment, in a specific implementation, the controller 4 includes a storage unit 41, a judgment unit 42, and a control unit 43; a relationship table is preset in the storage unit 41, and the relationship table at least includes the corresponding relationship between the conduction temperature and the conduction current of the electrical connection port 2; the judgment unit 42 is signal-connected to the storage unit 41 and the first temperature sensor 3 to determine the conduction current of the electrical connection port 2 according to the relationship table and the conduction temperature of the conducted electrical connection port 2; and the judgment unit 42 is electrically connected to the power supply component 1 and can determine the remaining available conduction current according to the total available conduction current provided by the power supply component 1 and the conduction current of the electrical connection port 2; the control unit 43 is signal-connected to the judgment unit 42 and the power supply component 1 to adjust the remaining available conduction current of other electrical connection ports 2 according to the remaining available conduction current.

[0052] It can be understood that, in order to enable the controller 4 to receive the detection data of the first sensor 3 and be able to obtain the conduction current of the electrical connection port according to this data while adjusting the remaining available conduction current of other electrical connection ports 2, in this embodiment, the controller 4 is set in the form including a storage unit 41, a judgment unit 42, and a control unit 43. The storage unit 41 can store, read, and write data, which can be but is not limited to a semiconductor memory, a RAM (random access memory) memory, an optical disc, a flash memory, a liquid hard disk, etc.; the judgment unit 42 can perform data processing, which can be but is not limited to including data operations, logical operations, comparison judgments, etc.; the controller unit 43 can execute instructions according to a predetermined strategy; in this embodiment, the storage unit 41 and the judgment unit 42 are jointly included in the EC, and the control unit 43 is included in the PD. The cooperation of the three can refer to the cooperation between the EC and the PD described above, and will not be elaborated here. The relationship table in this embodiment is preset in the storage unit 41, and the relationship table stores the corresponding relationship between different temperatures and different conduction currents. Subsequently, the judgment unit 42 can compare the data of the first temperature sensor 3 according to this relationship table to determine the conduction current at a certain temperature. This relationship table can be a large amount of data obtained through experiments; this relationship table can generate corresponding relationship tables after actual test detections according to different device types, different types of electrical connection ports 2, and different power supply components 1, and will not be limited here.

[0053] Further, referring to the attached Figure 2 , in the electronic device provided in this embodiment, in a specific implementation, the controller 4 further includes a timing unit 44; the timing unit 44 is electrically connected to the judgment unit 42 to send a timing end signal to the judgment unit 42, and the judgment unit 42 can determine the conduction current of the electrical connection port 2 according to the timing end signal.

[0054] It can be understood that, in order to improve accuracy, a timing unit 44 is provided in this embodiment. The timing unit 44 can be, but is not limited to, a timer, a counter, a timing chip, an oscillator, a clock unit, etc., and it can measure the target time period through timing or countdown; because the current delivery duration is different at the beginning and after a certain period of time when the electrical connection port 2 is turned on, the heat generation and even the temperature on the corresponding trace are necessarily different. Therefore, in this embodiment, the timing unit 44 cooperates with the judgment unit 42 to obtain the temperature at a certain frequency to ensure the accuracy of the temperature data and improve the flexibility of real-time detection and real-time adjustment; the specific timing period can be designed and adjusted according to actual needs, for example: 5s, 10s, 20s, etc.

[0055] Further, referring to the appendix Figure 2 In this embodiment, the electronic device further includes a second temperature sensor 5. The second temperature sensor 5 is disposed in the space between the power supply component 1 and the plurality of electrical connection ports 2 to obtain the ambient temperature of the space to which the electrical connection port 2 belongs when it is turned on. The judgment unit 42 is in signal connection with the second temperature sensor 5 to determine the true conduction temperature of the electrical connection port 2 according to the ambient temperature and the conduction temperature of the turned-on electrical connection port 2, and determine the remaining available conduction current according to the total available conduction current provided by the power supply component 1 and the true conduction current of the electrical connection port 2. The control unit 3 adjusts the available conduction current of other electrical connection ports 2 according to the remaining available conduction current.

[0056] It can be understood that, in order to improve the accuracy of control, a second sensor 5 is provided in this embodiment. The second temperature sensor 5 can be the same or different temperature detection element as the first temperature sensor 3, and is used to detect the ambient temperature inside the electronic device where the first temperature sensor 3 is located. There are other heat-generating components inside the electronic device, such as the CPU, GPU, etc. Therefore, when the first temperature sensor 3 performs temperature detection, it will be more or less affected by the heat of other heat-generating components. Therefore, the temperature data obtained by the first temperature sensor 3 cannot accurately represent the heat generation of the trace of the electrical connection port 2 where it is located. It includes the self-heat generation of the trace and the ambient temperature inside the electronic device where it is located. Therefore, in this embodiment, the second temperature sensor 5 is provided to detect the ambient temperature, and the temperature data of the first sensor 3 is synchronously transmitted to the judgment unit 42. The judgment unit 42 will subtract the temperature data of the second temperature sensor 5 from the temperature data of the first sensor 3 to obtain the actual temperature of the trace. Then, the conduction current corresponding to this temperature is the true conduction current of the electrical connection port 2, thereby improving the accuracy of obtaining the conduction current and ensuring the accuracy of dynamic adjustment.

[0057] Further, referring to the appendix Figure 2, in specific implementation of the electronic device provided in this embodiment, when at least two of the electrical connection ports 2 are simultaneously connected to an external electronic device and the sum of the conduction currents required by at least two of the electrical connection ports 2 is greater than the total conduction current provided by the power supply component 1, the controller 4 controls the conduction of a specified electrical connection interface 2 according to a preset rule.

[0058] It can be understood that, to ensure practicality, a preset rule is set in the controller 4 in this embodiment. When two or more electrical connection ports 2 are simultaneously connected to an external electronic device and the sum of the rated currents required by the external electronic devices obtained during the handshake process is greater than the total conduction current that the power supply component 1 can provide, it means that the total conduction current is not sufficient to conduct all the electrical connection ports 2. Then, the controller 4 executes the preset rule to conduct a specified electrical connection interface 2, and during the subsequent dynamic adjustment process, the unconducted electrical connection interfaces 2 are conducted in a timely manner according to the remaining conduction current. The preset rule in this embodiment can be a rule that forms priorities according to the plugging sequence of the electrical connection ports 2. For example, the first external electronic device and the second external electronic device are plugged into the first electrical connection port 2 and the second electrical connection port 2 successively with little difference. During the handshake process, the controller 4 determines that the sum of the rated currents required by the two is greater than the total conduction current that the power supply component 1 can provide. Then, the controller 4 first conducts the first electrical connection port 2 according to the rated voltage of the first external electronic device based on the principle of preferential conduction of the first plugged-in device. Subsequently, according to the temperature detection, if the conduction current of the first electrical connection port 2 is less than the rated current of the first external electronic device, the excess current is allocated to the second electrical connection port 2, making it possible for the second external electronic device connected to the second electrical connection port 2 to be conducted.

[0059] Of course, the preset rule can also be designed and adjusted according to actual needs. For example, priorities can be set according to the types of external electronic devices. It can be, but is not limited to, that input devices have a higher priority than output devices, or it can be the priority of external electronic devices default in the electronic device system. Input devices include, but are not limited to, keyboards, mice, and microphones, and output devices include, but are not limited to, displays, power banks, and microphones.

[0060] Furthermore, in specific implementation of the electronic device provided in this embodiment, when any one of the electrical connection ports 2 is connected to an external electronic device and the conduction current required by it is greater than its conduction current, the controller 4 cuts off the conduction of the external electronic device.

[0061] It can be understood that, in order to improve efficiency, a conduction determination principle is set in the controller 4 in this embodiment. When any electrical connection port 2 is connected to an external electronic device and the required conduction current is greater than its available conduction current, the controller 4 cuts off the conduction of the external electronic device; the available conduction current here can be the total available conduction current or the remaining available conduction current. For example, when all electrical connection ports 2 are not conducting, the available conduction current is the total available conduction current; when at least one electrical connection port 2 is conducting, the available conduction current is the remaining conduction current; the required conduction current of the external electronic device here is the rated current because the external electronic device starts the electrical connection with the electronic device with the rated current as the initial conduction current. When the rated current of the external electronic device is greater than the available conduction current of its corresponding electrical connection port 2, the controller 4 cuts off the conduction of the external electronic device, that is, it does not recognize it.

[0062] Further, referring to the appendix Figure 2 , in the specific implementation of the electronic device provided in this embodiment, there are also several indicator lights 6; several of the indicator lights 6 are arranged outside the electronic device in one-to-one correspondence with several of the electrical connection ports 2, and the indicator lights 6 are signal-connected to the controller 4; among them, when any electrical connection port 2 is connected to an external electronic device and the required conduction current is greater than its available conduction current, the controller 4 controls the corresponding indicator light 6 to light up.

[0063] It can be understood that, in order to improve practicality, the indicator lights 6 are provided in this embodiment. The indicator lights 6 can be light beads in the form of single-color, color-changing, etc. An indicator light is provided at the position of each electrical connection port 2, or the indicator lights 6 can be arranged around the electrical connection ports 2; when the external electronic device connected to a certain electrical connection port 2 cannot be recognized, the controller 4 will control the corresponding indicator light 6 to light up to clearly indicate the user, improve the indication efficiency, and avoid the problem that the display on the display screen of the electronic device in the form of a menu bar or window is not obvious.

[0064] In this embodiment, the detection result of the first temperature sensor 3 can also be associated with heat dissipation. For example, a fan can be provided inside the electronic device to dissipate heat from positions such as the motherboard, control panel, and input keyboard. The first temperature sensor 3 detects the temperature of the power supply trace inside the electronic device, and the temperature of the power supply trace will affect the temperature inside the electronic device and even reduce the heat dissipation efficiency. Therefore, in this embodiment, it can be set that when the temperature of the power supply trace reaches a specified temperature, the controller 4 controls the fan to blow air. Then, this specified temperature is a temperature point that can cause the temperature inside the electronic device to increase rapidly, and it can be designed and adjusted according to actual needs. At this time, controlling the fan to blow air can be before the traditional heat dissipation air outlet timing to improve the heat dissipation efficiency. And it can be understood that the air outlet intensity of the fan can also be adjusted according to the detection result of the first temperature sensor 3. This setting can be easily understood by those skilled in the art and will not be elaborated here too much.

[0065] It can be understood that the above embodiment content can be combined and coexist according to actual needs.

[0066] As described above, the above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all 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.
