[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0033] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0034] As an essential accessory for electronic products, cables provide flexible charging and data transfer capabilities. However, in practical applications, the functionality of cables cannot meet the diverse functional needs of electronic devices during the charging process.

[0035] Based on the above technical problems, this utility model provides a cable, data cable and electronic device with display function. Figure 1 This is a schematic diagram of the wire structure provided in the embodiment of the present utility model, as shown below. Figure 1 As shown, wire 100 includes:

[0036] Cable 101 includes multiple conductors 1011 and a sheath 1012; wherein, the sheath 1012 surrounds and wraps the multiple conductors for insulation and protection of the multiple conductors 1011; the multiple conductors are used to transmit electrical energy and / or data;

[0037] The first connector 102 includes a circuit board 1021, a plug-in portion 1022, and a display portion 1023; the circuit board 1021 is electrically connected to multiple wires; the circuit board includes a control circuit 1024, which is electrically connected to the display portion and the plug-in portion; wherein:

[0038] When the connector 1022 is electrically connected to the electronic device, it sends the transmission status to the control circuit 1024; the control circuit 1024 receives the transmission status and sends the remaining charging time and / or remaining transmission time corresponding to the transmission status to the display unit; the display unit receives and displays the remaining charging time and / or remaining transmission time.

[0039] The transmission status is associated with the electrical energy and / or data transmitted by the cable.

[0040] In one embodiment, the electrical energy transmitted by the wire 100 can be alternating current or direct current.

[0041] In one embodiment, the wire 100 can transmit electrical energy and data bidirectionally and / or unidirectionally.

[0042] In one embodiment, the circuit board may include an integrated circuit board.

[0043] In one embodiment, the connector may include a standard power transmission interface or a data transmission interface; for example, the connector may include a Universal Serial Bus (USB) interface and a Type-C interface, etc.

[0044] In one embodiment, the display unit may include circuits or electronic components with data display function.

[0045] In one embodiment, the control circuit may include at least one of the following: Application-Specific Integrated Circuit (ASIC), Digital Signal Processor (DSP), Digital Signal Processing Device (DSPD), Programmable Logic Device (PLD), Field Programmable Gate Array (FPGA), Central Processing Unit (CPU), Controller, Microcontroller Unit (MCU), and Microprocessor.

[0046] In one embodiment, the electronic device may include a power supply device or a power consumption device. In this case, the wire 100 can transmit the electrical energy output by the power supply device to the power consumption device. For example, the power consumption device may include a mobile electronic device, such as a drone, a mobile phone, a wireless headset, and a smartwatch or smart wearable device.

[0047] In one embodiment, the electronic device may include a data output device and a data receiving device, in which case the cable 100 can transmit the data output by the data output device to the data receiving device.

[0048] In one implementation, the transmission status may include the remaining charging time of the electrical energy transmitted by the cable, and / or the remaining transmission time of the transmitted data.

[0049] In one embodiment, after receiving the transmission status, the control circuit can analyze the transmission status to determine the data type and / or quantity contained in the transmission status. For example, if the transmission status includes the remaining charging time and the remaining transmission time, the remaining charging time and the remaining transmission time are converted into a data format that the display unit can display, and the converted data format remaining charging time and the remaining transmission time are sent to the display unit.

[0050] As can be seen from the above, the cable provided by this utility model includes multiple conductors for transmitting electrical energy and / or data, and a sheath surrounding and wrapping the multiple conductors to insulate and protect them. Thus, the cable has the function of safely transmitting electrical energy and / or data. Furthermore, when the plug portion of the first connector of the cable is electrically connected to an electronic device, it sends the transmission status associated with the electrical energy and / or data transmitted by the cable to the control circuit, realizing the synchronization of the transmission status between the plug portion and the control circuit. On this basis, the control circuit receives and sends the remaining charging time and / or remaining transmission time corresponding to the transmission status to the display unit, so that the display unit can receive and display the remaining charging time and / or remaining transmission time. Thus, the data cable provided by this utility model can flexibly and intuitively display the remaining charging time and / or remaining transmission time during the transmission of data and / or electrical energy, so that it meets the intuitive display requirements of the remaining charging time of electrical energy and / or the remaining transmission time of data during the charging and / or data transmission of electronic devices.

[0051] When the electronic device is a mobile phone or a smart wearable device, the cable provided by this utility model can flexibly and intuitively display the remaining power transmission time and / or data transmission time of the mobile phone or smart wearable device without turning on the screen.

[0052] Based on the foregoing embodiments, in the wire 100 provided by this utility model, the interval between the plug-in part 1022 and the display part 1023 is less than 5cm and greater than 1mm.

[0053] Thus, the above-mentioned settings can reduce the obstruction of the plug-in part on the remaining transmission time and / or remaining charging time displayed on the display part, and also provide convenience for users to view the remaining transmission time and / or remaining charging time.

[0054] Based on the foregoing embodiments, the display unit provided by this utility model includes indicator lights, indicator light arrays, or display screens.

[0055] In one embodiment, if the display is an indicator light, the remaining transmission time and / or remaining charging time can be indicated by different colors.

[0056] In one embodiment, if the display unit is an indicator light array or a display screen, the remaining transmission time and / or the remaining charging time can be directly displayed.

[0057] Figure 2A This is a top view of the wire provided by this utility model. Figure 2B This is a side view of the wire provided by this utility model. Figure 2C This is a cross-sectional view of the wire portion provided by this utility model. Figure 2D The schematic diagram of the wire circuit provided for this utility model.

[0058] like Figure 2A and 2B As shown, there is a gap between the connector 1022 and the display unit 1023, thereby reducing the impact of the connector on the data display process of the display unit; as Figure 2C As shown, the control circuit 1024 and the display unit 1023 can be integrated into a single design, thereby reducing the volume and size of the wiring; as Figure 2D As shown, the control circuit 1024 directly controls the display unit 1023, thereby enabling flexible control of the display unit.

[0059] Therefore, the display section of the cable provided by this utility model includes indicator lights, indicator light arrays or display screens, thereby enabling flexible display of the remaining charging time and / or remaining transmission time.

[0060] In this invention, the transmission state includes the power transmission rate and / or the data transmission rate.

[0061] In one embodiment, the power transmission rate may include the power of the electrical energy transmitted by the wire; for example, the power may be determined by the product of the voltage and current of the electrical energy transmitted by the wire.

[0062] Figure 3 Another structural schematic diagram of the wire provided by this utility model is shown below. Figure 3 As shown, the circuit board also includes a detection circuit 1025, which is electrically connected to the plug-in portion and the control circuit 1024. If the plug-in portion is electrically connected to an electronic device, the detection circuit 1025 detects the power transmission rate and / or data transmission rate, and sends the power transmission rate and / or data transmission rate to the control circuit 1024.

[0063] In one embodiment, the detection circuit 1025 may perform a detection operation in response to the control of the control circuit 1024, thereby obtaining and transmitting the power transmission rate and / or data transmission rate to the control circuit 1024.

[0064] In one embodiment, after obtaining the power transmission rate and / or data transmission rate, the control circuit 1024 can determine the remaining charging time and / or remaining transmission time by combining the remaining transmitted power and the remaining transmitted data. For example, the remaining transmitted power can be determined based on the difference between the total transmitted power and the transmitted power, the remaining transmitted data can be determined based on the difference between the total transmitted data and the transmitted data, and the transmitted power can be determined based on the power transmission rate and the transmitted time, and the transmitted data can be determined based on the data transmission rate and the transmitted time.

[0065] As can be seen from the above, the detection circuit in the circuit board of the wire provided by this utility model can detect and transmit the power transmission rate and / or data transmission rate to the control circuit, thereby realizing the synchronization of the power transmission rate and / or data transmission rate between the detection circuit and the control circuit.

[0066] Based on the foregoing embodiments, in the wire provided by this utility model, the detection circuit 1025 is also used to detect the remaining power and / or the remaining data, and send the remaining power and / or the remaining data to the control circuit 1024.

[0067] In one implementation, when the detection circuit detects that the plug is electrically connected to the electronic device, it can act as a SORCE to charge the electronic device at the moment of power-on, and then switch to the charging role to act as a SINK role to obtain information about the amount of electricity that the electronic device can release, i.e., the remaining electricity. Through the above logic, the remaining electricity and the power capacity of the electronic device can be successfully obtained in the early stage of power-on.

[0068] As can be seen from the above, the wire provided by this utility model, and the detection circuit, are also used to detect the remaining power and / or remaining data of the electronic device, and send the remaining power and / or remaining data to the control circuit. Thus, flexible detection of the remaining power and / or remaining data of the electronic device is achieved, and synchronization of the remaining power and / or remaining data between the detection circuit and the control circuit is also possible.

[0069] Based on the foregoing embodiments, in the cable 100 provided by this utility model, the control circuit 1024 sends the remaining power and / or remaining data to the display unit so that the display unit can display the remaining power and / or remaining data.

[0070] In one embodiment, the control circuit 1024 can determine whether to send the remaining battery power to the display unit based on the display status. For example, if the display status indicates that the remaining battery power can no longer be displayed in the display area of ​​the display unit, then the remaining battery power can be left unsent to the display unit.

[0071] In one embodiment, the control circuit can determine how the display unit should display the remaining battery power and / or remaining data based on the display status. For example, if the display status indicates that the display area of ​​the display unit can no longer display the remaining battery power and / or remaining data, the control circuit can control the display unit to alternately switch the data displayed in the display area at specified time intervals so that the display unit can fully display the remaining battery power and / or remaining data.

[0072] As can be seen from the above, the cable provided by this utility model allows the control circuit to send the remaining power and / or remaining data to the display unit, so that the display unit can display the remaining power and / or remaining data. In this way, through the cooperation between the control circuit and the display unit, the range and types of data that the display unit can display are expanded, thereby realizing an intuitive and flexible display of the remaining power and / or remaining data of the electronic device.

[0073] Based on the foregoing embodiments, in the wire 100 provided by this utility model, the control circuit sends a detection command to the detection circuit.

[0074] The detection command is used to trigger the detection circuit to perform the detection operation.

[0075] In one implementation, when the control circuit detects that the connector is electrically connected to an electronic device, it can generate and send a detection command to the detection circuit to trigger it to perform a detection operation.

[0076] In one implementation, the detection operation can detect the remaining power and / or the remaining data, as well as the power transmission rate and / or data transmission rate.

[0077] As can be seen from the above, the wire provided by this utility model allows the control circuit to send a detection command to the detection circuit to trigger the detection circuit to perform a detection operation. This achieves precise control of the detection circuit by the control circuit over the detection operation performed by the detection circuit.

[0078] Based on the foregoing embodiments, the wire provided by this utility model includes an input circuit 1026 electrically connected to a control circuit for responding to detection control operations and sending control parameters corresponding to the detection control operations to the control circuit. The control circuit receives the control parameters and sends detection commands corresponding to the control parameters to the detection circuit.

[0079] In one embodiment, the input circuit 1026 may include circuit elements having key input, voice input, and switch option input; correspondingly, the control operation may include key operation, voice command corresponding to voice data, and enable option for on / off detection operation corresponding to switch option.

[0080] In one embodiment, after responding to a control operation, the input circuit 1026 can trigger the control circuit to send periodic or single detection commands to the detection circuit according to a preset detection frequency.

[0081] In one implementation, the control operation, control parameters, and detection instructions can correspond one-to-one. For example, if the control operation is to detect the remaining electrical energy, then the control parameters are the time and / or conditions for detecting the remaining electrical energy, and the detection instructions are instructions to detect the remaining electrical energy according to the aforementioned time and / or conditions.

[0082] As can be seen from the above, the wire and circuit board provided by this utility model also include an input circuit, which is electrically connected to the control circuit. This input circuit responds to control operations and sends control parameters corresponding to the control operations to the control circuit, triggering the control circuit to send detection commands corresponding to the control parameters to the detection circuit. Thus, by responding to control operations through the input circuit, the detection operation of the detection circuit can be flexibly controlled through the control circuit.

[0085] In one embodiment, the connector may also be a standard data transmission bus interface, capable of bidirectional transmission of power and / or data; for example, the interface type corresponding to the connector may be the same as or different from the interface type corresponding to the plug.

[0087] As can be seen from the above, the data cable provided by this utility model, by electrically connecting the connector to the end of the cable away from the plug, can not only realize the transmission of electrical energy and / or data, but also display the remaining charging time and / or remaining transmission time during the transmission of electrical energy and / or data, thereby expanding the functional range of the data cable.

[0091] The second connector 502 is electrically connected to the end of the wire away from the first connector; the indicator 503 is electrically connected to the control circuit of the wire, and the indicator at least receives and displays the transmission status sent by the control circuit.

[0092] The transmission status includes whether power transmission and / or data transmission are completed.

[0093] In one embodiment, the second connector 502 can be a standard data interface and can enable bidirectional transmission of data and / or electrical energy.

[0094] In one embodiment, the interface type corresponding to the second connector 502 may be the same as or different from the interface type corresponding to the plug part.

[0095] In one embodiment, indicator 503 may include indicator lights, indicator light arrays, or displays.

[0096] In one embodiment, the control circuit can transmit the data to be displayed to the display unit and the indicator unit respectively. In other words, the indicator unit can display all the data that the display unit can display.

[0097] In one embodiment, the electronic device may include devices such as chargers, power strips, and power banks.

[0098] In one implementation, the control circuit can determine whether power transmission and / or data transmission is complete based on the remaining charging time and / or the remaining transmission time, and can also determine whether power transmission and / or data transmission is complete based on the remaining power and / or the remaining data amount.

[0099] As can be seen from the above, the electronic device provided by this utility model has its main body connected to the end of the cable away from the plug-in portion, and the second connector in the main body connected to the end of the cable away from the first connector.
