Description

Technical Field

[0001] This application belongs to the field of control technology, specifically relating to an electronic device and its control method. Background Technology

[0002] To provide a wider viewing angle and a better visual experience, foldable screen devices have emerged. Foldable screen devices generally have two bodies, left and right, connected by a rotating flexible printed circuit (FPC). When the power supply and power-consuming components are located in different bodies, the longer wiring results in a higher impedance in the power supply path. This leads to a larger difference between the output voltage of the power supply and the input voltage of the power-consuming components, causing not only energy consumption issues but also preventing the power-consuming components from being effectively activated when the output voltage of the power supply is low.

[0003] To overcome the above problems, related technical solutions often adopt the approach of increasing the width and thickness of the traces in the flexible circuit board to reduce impedance. However, increasing the width and thickness of the traces will affect the space occupied by the FPC and is not conducive to the layout of the FPC. Summary of the Invention

[0004] The purpose of this application is to provide an electronic device and its control method that can reduce the footprint of FPC while lowering the trace impedance.

[0005] In a first aspect, embodiments of this application provide an electronic device, comprising: a first folding body, wherein a controller and a power supply device are disposed in the first folding body; a second folding body, wherein a first functional device and a second functional device are disposed in the second folding body; a flexible circuit board, wherein the flexible circuit board has a first connecting line and a second connecting line, and a first switch and a second switch are disposed on the flexible circuit board; wherein, a first moving end of the first switch is connected to the first connecting line, and a first stationary end and a second stationary end of the first switch are respectively connected to the controller and the power supply device; a second moving end of the second switch is connected to the first connecting line, and a third stationary end and a fourth stationary end of the second switch are respectively connected to the first functional device and the second functional device; a second connecting line is connected between the second functional device and the power supply device; when the first functional device is in a working state, the first moving end and the first stationary end are connected, the second moving end and the third stationary end are connected, and the first functional device is electrically connected to the controller through the first connecting line; when the first functional device is not in a working state and the second functional device is in a working state, the first moving end and the second stationary end are connected, the second moving end and the fourth stationary end are connected, and the second functional device is electrically connected to the power supply device through the first connecting line and the second connecting line.

[0006] Secondly, embodiments of this application provide a control method for an electronic device, including:

[0007] The operating states of the first functional device and the second functional device are obtained. When the first functional device is in the operating state, the first moving end and the first stationary end of the first switch are connected, and the second moving end and the third stationary end of the second switch are connected. The first functional device is electrically connected to the controller through the first connecting line. When the first functional device is not in the operating state and the second functional device is in the operating state, the first moving end and the second stationary end of the first switch are connected, and the second moving end and the fourth stationary end of the second switch are connected. The second functional device is electrically connected to the power supply device through the first connecting line and the second connecting line.

[0008] Thirdly, embodiments of this application provide a control device for an electronic device, comprising: an acquisition module for acquiring the operating states of a first functional device and a second functional device; and a processing module for controlling the first moving end and the first stationary end of a first switch to be connected, and controlling the second moving end and the third stationary end of a second switch to be connected, when the first functional device is in an operating state, wherein the first functional device is electrically connected to a controller via a first connecting line; and controlling the first moving end and the second stationary end of the first switch to be connected, and controlling the second moving end and the fourth stationary end of the second switch to be connected, when the first functional device is not in an operating state and the second functional device is in an operating state, wherein the second functional device is electrically connected to a power supply device via a first connecting line and a second connecting line.

[0009] Fourthly, embodiments of this application provide an electronic device including a processor and a memory, the memory storing a program or instructions executable on the processor, the program or instructions, when executed by the processor, implementing the steps of the method as described in the second aspect.

[0010] Fifthly, embodiments of this application provide a readable storage medium on which a program or instructions are stored, which, when executed by a processor, implement the steps of the method as described in the second aspect.

[0011] In a sixth aspect, embodiments of this application provide a chip, which includes a processor and a communication interface. The communication interface and the processor are coupled, and the processor is used to run programs or instructions to implement the method as described in the second aspect.

[0012] In a seventh aspect, embodiments of this application provide a computer program product stored in a storage medium, which is executed by at least one processor to implement the method as described in the second aspect.

[0013] In this embodiment of the application, by setting a first switch and a second switch, the first switch and the second switch can be controlled, thereby realizing the reuse of the first connecting line and the second connecting line in the flexible circuit board.

[0014] In this process, data transmission or power supply is carried out by reusing the first and second connecting lines. Compared with the transmission scheme using a single connecting line, the width of the connecting line is increased, thereby reducing the impedance. This reduces the drop in the output voltage of the power supply device caused by the operation of the first or second functional device on the second folded body. It also reduces the probability that the power supply device cannot effectively activate power-consuming devices when the output voltage is low, making the electronic equipment system work stably and reducing the probability of UVP (Under Voltage Protection) causing system crashes or abnormal shutdowns.

[0015] In addition, reducing trace impedance does not require increasing trace width and thickness, which is beneficial for FPC layout. Attached Figure Description

[0026] The electronic device and its control method provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0027] In one embodiment, such as Figure 1 As shown, an electronic device is proposed, comprising: a first folding body 100, in which a controller 102 and a power supply device 104 are disposed; a second folding body 200, in which a first functional device 202 and a second functional device 204 are disposed; a flexible circuit board 300, having a first connecting line 302 and a second connecting line 304, and having a first switch K1 and a second switch K2 disposed on the flexible circuit board 300; wherein, the first moving end of the first switch K1 is connected to the first connecting line 302, and the first and second stationary ends of the first switch K1 are respectively connected to the controller 102 and the power supply device 104; the second moving end of the second switch K2 is connected to the first connecting line 302. The third and fourth stationary terminals of the second switch K2 are connected to the first functional device 202 and the second functional device 204, respectively. The second connecting line 304 is connected between the second functional device 204 and the power supply device 104. When the first functional device 202 is in working state, the first moving terminal and the first stationary terminal are connected, the second moving terminal and the third stationary terminal are connected, and the first functional device 202 is electrically connected to the controller 102 through the first connecting line 302. When the first functional device 202 is not in working state and the second functional device 204 is in working state, the first moving terminal and the second stationary terminal are connected, the second moving terminal and the fourth stationary terminal are connected, and the second functional device 204 is electrically connected to the power supply device 104 through the first connecting line 302 and the second connecting line 304.

[0029] In this process, data transmission or power supply is carried out by reusing the first connection line 302 and the second connection line 304. Compared with the transmission scheme using a single connection line, the width of the connection cable is increased, thereby reducing the impedance. This reduces the drop in the output voltage of the power supply device 104 caused by the operation of the first functional device 202 or the second functional device 204 on the second folded body 200. It also reduces the probability that the power-consuming device cannot be effectively activated when the output voltage of the power supply device is low, making the electronic equipment system work stably and reducing the probability of UVP (Under Voltage Protection) causing system crashes or abnormal shutdowns.

[0030] In addition, while reducing the trace impedance, the width and thickness of the traces are not increased, eliminating the impact of flexible circuit boards on space occupation and facilitating the layout of FPCs.

[0031] Meanwhile, data is transmitted by reusing the first connection line 302 and the second connection line 304 to improve the stability of data transmission.

[0032] Furthermore, in the embodiments of this application, if one of the first connecting line 302 and the second connecting line 304 is damaged and cannot transmit data or supply power, the other connecting line can be used to transmit data and supply power, so as to improve the reliability of the electronic device and extend the service life of the electronic device.

[0033] In some embodiments of this application, the first folding body 100 and the second folding body 200 can be understood as the body of a foldable screen phone that can be folded together.

[0034] For example, the left and right sides of a two-fold folding machine that can be folded left and right, or the top and bottom of a two-fold folding machine that can be folded up and down, or any two of the three-fold folding machines.

[0035] In some embodiments of this application, the controller 102 can be understood as the central processing unit (CPU) of an electronic device, or as a microcontroller unit (MCU) with control functions.

[0037] In the above embodiments, the first functional device 202 and the second functional device 204 listed are only commonly used components. Electronic devices can select the corresponding components according to actual usage needs, and the components they refer to will not be described in detail here.

[0038] In some embodiments of this application, the flexible circuit board 300 is further provided with a third switch K3 and a fourth switch K4; the third moving end of the third switch K3 is connected to the second connecting line 304, the fifth and sixth stationary ends of the third switch K3 are respectively connected to the power supply device 104 and the controller 102, the fourth moving end of the fourth switch K4 is connected to the second connecting line 304, and the seventh and eighth stationary ends of the fourth switch K4 are respectively connected to the first functional device 202 and the second functional device 204; wherein, when the first functional device 202 is in the working state and the second functional device 204 is not in the working state, the first moving end... The first moving terminal is connected to the first stationary terminal, the second moving terminal is connected to the third stationary terminal, the third moving terminal is connected to the fifth stationary terminal, and the fourth moving terminal is connected to the seventh stationary terminal. The first functional device 202 is electrically connected to the controller 102 through the first connecting line 302 and the second connecting line 304. When the first functional device 202 is not in working state and the second functional device 204 is in working state, the first moving terminal and the second stationary terminal are connected, the second moving terminal is connected to the fourth stationary terminal, the third moving terminal is connected to the sixth stationary terminal, and the fourth moving terminal is connected to the eighth stationary terminal. The second functional device 204 is electrically connected to the power supply device 104 through the first connecting line 302 and the second connecting line 304.

[0041] At the same time, it reduces the drop in output voltage of power supply device 104 caused by the operation of the first functional device 202 or the second functional device 204 on the second folding body 200, so that the electronic equipment system operates stably and the probability of UVP (Under Voltage Protection) causing system crashes or abnormal shutdowns is reduced.

[0042] In some embodiments of this application, the controller 102 has an output terminal, the power supply device 104 has a power supply terminal, the first functional device 202 has a data terminal, and the second functional device 204 has a power consumption terminal.

[0043] The output terminal mentioned above can realize data transmission, such as receiving data and / or sending data; the power supply terminal can be understood as the power supply output terminal, and the circuit or equipment connected to the power supply output terminal can draw power from the power supply device 104 to operate; the power consumption terminal, which corresponds to the power supply terminal, can be understood as providing power to it so that the circuit or equipment it is connected to can draw power to operate; the data terminal, which corresponds to the output terminal, can transmit data.

[0044] In some embodiments of this application, the output terminal includes a first output terminal and a second output terminal connected together; the power supply terminal includes a first power supply terminal and a second power supply terminal connected together; the data terminal includes a first data terminal and a second data terminal connected together; the power consumption terminal includes a first power consumption terminal and a second power consumption terminal connected together; the first stationary terminal of the first switch K1 is connected to the first output terminal; the second stationary terminal of the first switch K1 is connected to the first power supply terminal; the third stationary terminal of the second switch K2 is connected to the first data terminal; the fourth stationary terminal of the second switch K2 is connected to the first power consumption terminal; the fifth stationary terminal of the third switch K3 is connected to the second output terminal; the sixth stationary terminal of the third switch K3 is connected to the second power supply terminal; the seventh stationary terminal of the fourth switch K4 is connected to the second data terminal; and the eighth stationary terminal of the fourth switch K4 is connected to the second power consumption terminal.

[0045] In some embodiments of this application, the first switch K1 and the third switch K3 are integrated double-pole double-throw switches, and similarly, the second switch K2 and the fourth switch K4 are integrated double-pole double-throw switches.

[0046] In some embodiments of this application, such as Figure 2 As shown, when the first functional device 202 is working, C and E are connected to the first connecting line 302 and the second connecting line 304, respectively; while when the second functional device 204 is working, D and F are connected to the first connecting line 302 and the second connecting line 304, respectively.

[0047] In some embodiments of this application, the flexible circuit board 300 further includes a third connecting line 306, and the electronic device further includes: a first battery BT1 and a second battery BT2, the first battery BT1 being disposed on the first folding body 100; the second battery BT2 being disposed on the second folding body 200, the first battery BT1 and the second battery BT2 being connected in series through the third connecting line 306, and the first battery BT1 being electrically connected to the power supply device 104.

[0048] Specifically, the first end of the first battery BT1 is connected to the power supply device 104, the second end of the first battery BT1 is connected to the first end of the third connecting line 306, the first end of the second battery BT2 is connected to the second end of the third connecting line 306, and the second end of the second battery BT2 is connected to the second functional device 204.

[0049] In this embodiment, electronic devices need to be equipped with energy storage components such as batteries to store electrical energy during actual use, and then use the energy storage components to achieve power supply.

[0050] In the relevant technical solutions, a single-battery design is used. However, single-battery devices have the disadvantage of large cell size, which takes up a lot of space when installed in the folding body.

[0051] In the embodiments proposed in this application, a dual-battery design is adopted. By setting the first battery BT1 and the second battery BT2 in the first folding body 100 and the second folding body 200 respectively, the space occupied by each battery cell in the folding body is reduced, thereby ensuring that the first folding body 100 and the second folding body 200 have similar volume and weight to the greatest extent possible, so as to improve the user's grip experience.

[0052] In the above embodiment, by setting a third connecting line 306, the first battery BT1 and the second battery BT2 are connected in series to form an integrated energy storage element, which then outputs power to the outside. Compared with the design scheme where each battery outputs power independently, the difficulty of power supply control in electronic devices is reduced.

[0053] In some embodiments of this application, the first functional device 202 is a camera, and the second functional device 204 is a speaker 2044.

[0056] In some embodiments of this application, the voltage conversion circuit 2042 may be an integrated circuit, such as an integrated chip.

[0057] In some embodiments of this application, the voltage conversion circuit 2042 can be a boost converter circuit, a buck converter circuit, or a DC-to-AC converter circuit. It can be selected according to actual needs, and will not be described in detail here.

[0058] In some embodiments of this application, the second functional device 204 further includes an audio power amplifier device 2046 located between the voltage conversion circuit 2042 and the speaker 2044.

[0059] In this embodiment, an audio amplifier device 2046 is provided to provide a signal with appropriate power to the speaker 2044, thereby driving the speaker 2044 to produce sound.

[0060] Among them, the audio power amplifier device 2046 can be an audio power amplifier chip, such as LM386.

[0061] In some embodiments of this application, the first folding body 100 further includes: a first circuit board 106, a controller 102 and a power supply device 104 disposed on the first circuit board 106; the second folding body 200 further includes: a second circuit board 206, a first functional device 202 and a second functional device 204 disposed on the second circuit board 206.

[0062] In this embodiment, compared with the design using a single circuit board, the design using two circuit boards can reduce the installation space requirements of the circuit boards, thereby making the first folding body 100 and the second folding body 200 similar in size and weight, so as to improve the user's grip experience.

[0063] At the same time, it also helps to reduce interference between different circuits and modules on the circuit board, thereby improving the stability of electronic devices.

[0064] In some embodiments of this application, the electronic device further includes: a pivot 600, the first folding body 100 and the second folding body 200 being rotatably connected via the pivot 600, and a flexible circuit board passing through the pivot and electrically connected to the first circuit board and the second circuit board.

[0065] In this embodiment, a pivot is provided to enable a rotatable connection between the first folding body 100 and the second folding body 200.

[0066] In some embodiments of this application, the first functional device 202 may be a camera. Based on this, data is transmitted by multiplexing the first connection line 302 and the second connection line 304 in order to transmit image data captured by the camera. By multiplexing the first connection line 302 and the second connection line 304, the stability of image data transmission can be improved.

[0067] In some embodiments of this application, such as Figure 3 As shown, a control method for an electronic device is proposed, for any of the above embodiments of the electronic device, comprising:

[0068] Step 702: Obtain the operating status of the first functional device and the second functional device;

[0069] Step 704: When the first functional device is in working state, control the first moving end and the first stationary end of the first switch to be connected, control the second moving end and the third stationary end of the second switch to be connected, and the first functional device is electrically connected to the controller through the first connecting line;

[0071] In this embodiment, data transmission or power supply is performed by reusing the first and second connecting lines. Compared with the transmission scheme using a single connecting cable, the width of the connecting cable is increased, thereby reducing impedance. This reduces the drop in output voltage of the power supply device caused by the operation of the first or second functional device on the second folded body. It also reduces the probability that the power supply device cannot effectively activate power-consuming devices when the output voltage is low, making the electronic device system work stably and reducing the probability of UVP (Under Voltage Protection) causing system crashes or abnormal shutdowns.

[0072] In addition, while reducing the trace impedance, the width and thickness of the traces are not increased, eliminating the impact of flexible circuit boards on space occupation and facilitating the layout of FPCs.

[0073] At the same time, data is transmitted by reusing the first and second connection lines in order to improve the stability of data transmission.

[0074] Furthermore, in the embodiments of this application, if one of the first connecting line and the second connecting line is damaged and cannot transmit data or supply power, the other connecting line can be used to transmit data and supply power, so as to improve the reliability of the electronic device and extend the service life of the electronic device.

[0075] In some embodiments of this application, when a third switch and a fourth switch are provided on the flexible circuit board, when the first functional device is in a working state and the second functional device is not in a working state, the first moving end and the first stationary end of the first switch are controlled to be connected, the second moving end and the third stationary end of the second switch are controlled to be connected, the third moving end and the fifth stationary end of the third switch are controlled to be connected, and the fourth moving end and the seventh stationary end of the fourth switch are controlled to be connected. The first functional device is electrically connected to the controller through the first connecting line and the second connecting line. When the first functional device is not in a working state and the second functional device is in a working state, the first moving end and the second stationary end of the first switch are controlled to be connected, the second moving end and the fourth stationary end of the second switch are controlled to be connected, the third moving end and the sixth stationary end of the third switch are controlled to be connected, and the fourth moving end and the eighth stationary end of the fourth switch are controlled to be connected. The second functional device is electrically connected to the power supply device through the first connecting line and the second connecting line.

[0076] In this embodiment, the third and fourth switches can be configured to reuse the second connection line. During this process, the first and second connection lines are reused to transmit data, thereby improving the stability of data transmission.

[0077] At the same time, it reduces the drop in output voltage of the power supply device caused by the operation of the first or second functional device on the second folding body, making the electronic equipment system work stably and reducing the probability of UVP (Under Voltage Protection) causing system crashes or abnormal shutdowns.

[0078] In some embodiments of this application, the method further includes: when the first functional device and / or the second functional device exits the working state, controlling the first moving terminal to be connected to the first default stationary terminal and the second moving terminal to be connected to the second default stationary terminal; wherein, the first default stationary terminal is any one of the first stationary terminal and the second stationary terminal, and the second default stationary terminal is any one of the third stationary terminal and the fourth stationary terminal.

[0079] In this embodiment, by controlling the first moving terminal to be connected to the first default stationary terminal and the second moving terminal to be connected to the second default stationary terminal, the first switch and the second switch are restored to their initial states, thereby reducing the occurrence of situations such as sudden sound emission when the first functional device and / or the second functional device is started, which could cause abnormal noise in the electronic device.

[0080] In some embodiments of this application, obtaining the operating state of the first functional device and the second functional device includes: determining that the first functional device is operating when the function associated with the first functional device is enabled; and determining that the second functional device is operating when the function associated with the second functional device is enabled.

[0081] In this embodiment, the determination of whether the first and second functional devices are working can be achieved by checking the activation status of functions in the electronic device, thereby enabling the control of the first and second switches.

[0082] The control method for an electronic device provided in this application can be executed by a control device for the electronic device. This application uses the example of a control device for an electronic device executing the control method to illustrate the control device for the electronic device provided in this application.

[0083] In one embodiment, such as Figure 4 As shown, a control device 800 for an electronic device is provided, comprising: an acquisition module 802 for acquiring the operating states of a first functional device and a second functional device; and a processing module 804 for controlling the first moving end and the first stationary end of a first switch to be connected, and controlling the second moving end and the third stationary end of a second switch to be connected, when the first functional device is in the operating state, wherein the first functional device is electrically connected to a controller via a first connecting line; and controlling the first moving end and the second stationary end of the first switch to be connected, and controlling the second moving end and the fourth stationary end of the second switch to be connected, when the first functional device is not in the operating state and the second functional device is in the operating state, wherein the second functional device is electrically connected to a power supply device via a first connecting line and a second connecting line.

[0084] In this embodiment, data transmission or power supply is performed by reusing the first and second connecting lines. Compared with the transmission scheme using a single connecting cable, the width of the connecting cable is increased, thereby reducing impedance. This reduces the drop in output voltage of the power supply device caused by the operation of the first or second functional device on the second folded body. It also reduces the probability that the power supply device cannot effectively activate power-consuming devices when the output voltage is low, making the electronic device system work stably and reducing the probability of UVP (Under Voltage Protection) causing system crashes or abnormal shutdowns.

[0085] In addition, while reducing the trace impedance, the width and thickness of the traces are not increased, eliminating the impact of flexible circuit boards on space occupation and facilitating the layout of FPCs.

[0086] At the same time, data is transmitted by reusing the first and second connection lines in order to improve the stability of data transmission.

[0087] Furthermore, in the embodiments of this application, if one of the first connecting line and the second connecting line is damaged and cannot transmit data or supply power, the other connecting line can be used to transmit data and supply power, so as to improve the reliability of the electronic device and extend the service life of the electronic device.

[0100] Those skilled in the art will understand that the electronic device 1000 may also include a power supply (such as a battery) for supplying power to various components. The power supply may be logically connected to the processor 1010 through a power management system, thereby enabling functions such as managing charging, discharging, and power consumption through the power management system. Figure 6 The electronic device structure shown does not constitute a limitation on the electronic device. The electronic device may include more or fewer components than shown, or combine certain components, or have different component arrangements, which will not be elaborated here.

[0101] In one embodiment, the processor 1010 is configured to: acquire the operating states of a first functional device and a second functional device; when the first functional device is in an operating state, control the first moving end and the first stationary end of a first switch to be connected, control the second moving end of a second switch to be connected to the third stationary end, and the first functional device is electrically connected to a controller via a first connecting line; when the first functional device is not in an operating state and the second functional device is in an operating state, control the first moving end and the second stationary end of the first switch to be connected, control the second moving end of the second switch to be connected to the fourth stationary end, and the second functional device is electrically connected to a power supply device via a first connecting line and a second connecting line.

[0102] In one embodiment, when a third switch and a fourth switch are provided on the flexible circuit board 300, the processor 1010 is configured to: when the first functional device is in a working state and the second functional device is not in a working state, control the first moving end and the first stationary end of the first switch to be connected, control the second moving end of the second switch to be connected to the third stationary end, control the third moving end of the third switch to be connected to the fifth stationary end, control the fourth moving end of the fourth switch to be connected to the seventh stationary end, and the first functional device is electrically connected to the controller through a first connecting line and a second connecting line; when the first functional device is not in a working state and the second functional device is in a working state, control the first moving end and the second stationary end of the first switch to be connected, control the second moving end of the second switch to be connected to the fourth stationary end, control the third moving end of the third switch to be connected to the sixth stationary end, control the fourth moving end of the fourth switch to be connected to the eighth stationary end, and the second functional device is electrically connected to the power supply device through the first connecting line and the second connecting line.

[0105] In this embodiment, data transmission or power supply is performed by reusing the first and second connecting lines. Compared with the transmission scheme using a single connecting cable, the width of the connecting cable is increased, thereby reducing impedance. This reduces the drop in output voltage of the power supply device caused by the operation of the first or second functional device on the second folded body. It also reduces the probability that the power supply device cannot effectively activate power-consuming devices when the output voltage is low, making the electronic device system work stably and reducing the probability of UVP (Under Voltage Protection) causing system crashes or abnormal shutdowns.

[0106] In addition, while reducing the trace impedance, the width and thickness of the traces are not increased, eliminating the impact of flexible circuit boards on space occupation and facilitating the layout of FPCs.

[0107] At the same time, data is transmitted by reusing the first and second connection lines in order to improve the stability of data transmission.

[0108] Furthermore, in the embodiments of this application, if one of the first connecting line and the second connecting line is damaged and cannot transmit data or supply power, the other connecting line can be used to transmit data and supply power, so as to improve the reliability of the electronic device and extend the service life of the electronic device.
