Description

Technical Field

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

[0002] Batteries are widely used in various electronic devices. For example, a folding phone is equipped with a secondary battery, which is usually electrically connected to the main board through a circuit board (or "through-axis circuit board") that passes through the middle shaft of the folding phone, so as to be able to power the main board, thereby improving the battery life of the folding phone. When the secondary battery is discharged, the current will flow from the positive electrode of the secondary battery to the main board through the through-axis circuit board, and then flow back from the main board to the negative electrode of the secondary battery through the through-axis circuit board.

[0003] However, the length of the current through-axis circuit board is difficult to reduce, and the width is limited, and many types of wiring need to be set up, so the length of the discharge path (flowing from the positive pole of the secondary battery to the main board) and the length of the loop (flowing back from the main board to the negative pole of the secondary battery) of the secondary battery are long, and the width of the discharge path and the width of the ground loop are difficult to increase, resulting in a large discharge path impedance of the secondary battery. When the foldable phone works in a high current scenario, if the discharge path impedance of the secondary battery is large, the voltage of the secondary battery will drop significantly, affecting the voltage stabilization effect of the foldable phone. Summary of the invention

[0004] In order to solve the above technical problems, the present application provides an electronic device. The present application is introduced from multiple aspects below, and the implementation methods and beneficial effects of the following multiple aspects can be referenced to each other.

[0005] The first aspect of the present application provides an electronic device. The electronic device includes a housing, a first battery, a first circuit board, a connecting circuit board and a conductive connector. The first battery and the first circuit board are respectively located in different areas of the housing. The two ends of the connecting circuit board are electrically connected to the positive electrode of the first battery and the first circuit board, respectively, and the two ends of the conductive connector are electrically connected to the ground terminal of the first circuit board and the negative electrode of the first battery, respectively. The discharge current of the first battery flows from the positive electrode of the first battery to the first circuit board through the connecting circuit board; and flows back to the negative electrode of the first battery through the ground terminal of the first circuit board and the conductive connector.

[0006] According to the embodiment of the present application, the discharge current of the first battery can flow back from the first circuit board to the negative electrode of the first battery through the conductive connector, rather than from the first circuit board to the negative electrode of the first battery through the through-axis circuit board. In this way, the width of the loop line of the first battery will not be limited by the through-axis circuit board, and the loop line can be set as wide as possible. At the same time, there is no need to set up a loop line in the through-axis circuit board, so there is enough space to arrange a sufficiently wide discharge line, thereby effectively reducing the discharge path impedance of the first battery.

[0007] In a possible implementation of the first aspect, the conductive connector includes a conductive sheet, a first metal plate, and a second metal plate. The first metal plate is located in the same area as the first battery and is electrically connected to the negative electrode of the first battery. The second metal plate is located in the same area as the first circuit board and is electrically connected to the ground terminal of the first circuit board. One end of the conductive sheet is fixed to and electrically connected to the first metal plate, and the other end of the conductive sheet is fixed to and electrically connected to the second metal plate.

[0008] According to the implementation mode of the present application, since the first metal plate and the second metal plate have good strength, the first metal plate and the second metal plate can also provide a certain support for the electronic device, so that the electronic device can better resist external impact and pressure, thereby better protecting the components inside the electronic device.

[0009] In a possible implementation of the first aspect above, an orthographic projection area of ​​the conductive sheet on the first plane at least partially overlaps with an orthographic projection area of ​​the connecting circuit board on the first plane, and the first plane is a plane where the length direction of the electronic device and the width direction of the electronic device are located.

[0010] In this way, the discharge path of the first battery can be made into a relatively flat annular path as a whole, thereby effectively weakening the electromagnetic interference of the annular magnetic field coupled by the path on the first battery, thereby further improving the working performance of the first battery.

[0011] In a possible implementation of the first aspect, the housing includes a first housing and a second housing, the first battery is disposed on the first housing, the first circuit board is disposed on the second housing, the first housing and the second housing can rotate relative to each other around an axis extending in a first direction, and the conductive sheet can be bent around the axis extending in the first direction. In this way, the conductive sheet can better adapt to the movement of the first housing and the second housing.

[0012] In a possible implementation of the first aspect above, at least one elongated hole extending along the first direction is formed on the conductive sheet, and at least one elongated hole is arranged at intervals along a second direction, and the second direction is perpendicular to the first direction.

[0013] According to the embodiment of the present application, the elongated through hole can reduce the stiffness of the conductive sheet in the second direction to improve the bendability of the conductive sheet around an axis parallel to the first direction, thereby allowing the conductive sheet to better adapt to the movement of the first shell and the second shell.

[0014] In a possible implementation of the first aspect above, the elongated hole is a through hole.

[0015] In a possible implementation of the first aspect above, the elongated hole includes any one of a rectangular hole, an elliptical hole, a racetrack-shaped hole, a dumbbell-shaped hole, and a racetrack-dumbbell composite hole.

[0016] In a possible implementation of the first aspect above, the conductive sheet includes at least one hollow area, the at least one hollow area is arranged at intervals along a second direction, the second direction is perpendicular to the first direction, and the at least one hollow area includes a plurality of through holes arranged at intervals along the first direction.

[0017] In a possible implementation of the first aspect above, the conductive sheet and the first metal plate and the second metal plate are fixed and electrically connected by using one of the following connection methods: welding, fastener connection, and clamping.

[0018] In a possible implementation of the first aspect above, the conductive connecting member is made of metal.

[0019] In a possible implementation of the first aspect above, the connecting circuit board is a flexible circuit board.

[0020] In a possible implementation of the first aspect above, the electronic device further includes a second battery, the second battery and the first circuit board are located in the same area, and the second battery is electrically connected to the first circuit board.

[0021] In a possible implementation of the first aspect above, the first circuit board is a mainboard of the electronic device. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0039] The “first” and “second” involved in the embodiments of the present application are only defined for the convenience of distinguishing components and do not represent the actual meaning.

[0040] The embodiment of the present application is used to provide an electronic device. The electronic device provided by the present application includes a battery, and by redesigning the routing path of the battery return (from the main board to the negative electrode of the auxiliary battery), the width of the ground loop routing can be set as large as possible when the length is long, thereby effectively optimizing the discharge path impedance of the battery, thereby improving the voltage stabilization effect of the electronic device.

[0041] It can be understood that the electronic devices provided in the embodiments of the present application include but are not limited to mobile phones, tablet computers, e-book readers, laptop computers, personal digital assistants (PDAs), personal computers, notebooks, vehicle-mounted devices, wearable devices (e.g., smart glasses), and other electronic devices having at least two batteries located in different areas.

[0042] For the convenience of explanation, the following description is made by taking a folding mobile phone as an example of an electronic device. The folding mobile phone of the present application is introduced with specific embodiments.

[0043] Figure 1A and Figure 1B The exemplary structure of the foldable mobile phone 1 in the embodiment of the present application is shown, wherein: Figure 1A is a schematic diagram of the flattened state of the foldable mobile phone 1, Figure 1B It is a schematic diagram of the folding state of the folding mobile phone 1.

[0044] In order to facilitate the subsequent description, before introducing the specific structure of the foldable mobile phone 1, Figure 1A and Figure 1B The X-axis direction (as an example of the first direction), the Y-axis direction (as an example of the second direction), and the Z-axis direction corresponding to the foldable mobile phone 1 are defined. Figure 1A and Figure 1B , the X-axis direction is the width direction of the foldable mobile phone 1 when it is in the unfolded state; the Z-axis direction is the thickness direction of the foldable mobile phone 1 when it is in the unfolded state; the Y-axis direction is a direction perpendicular to both the X-axis direction and the Z-axis direction, for example, the Y-axis direction is the length direction of the foldable mobile phone 1. It should be noted that in this application, the XY plane is taken as an example of the first plane, the width of each component refers to the size of each component along the Y-axis direction, and the thickness of each component refers to the size of each component along the Z-axis direction, which will not be described in detail below.

[0045] refer to Figure 1A and Figure 1B The foldable phone 1 includes a housing 01, a rotating shaft 02 and a flexible screen 03. The housing 01 includes a first housing 11 and a second housing 12. Along the Y-axis direction, the first housing 11 and the second housing 12 are respectively arranged on opposite sides of the rotating shaft 02. The first housing 11 of the foldable phone 1 is rotatably connected to the rotating shaft 02, and the second housing 12 of the foldable phone 1 is rotatably connected to the rotating shaft 02. The flexible screen 03 covers the first housing 11, the second housing 12 and the rotating shaft 02. The first housing 11 and the second housing 12 can rotate synchronously through the rotating shaft 02, and drive the flexible screen 03 to bend or unfold, so that the foldable phone 1 can switch between the folded state and the unfolded state at will.

[0046] The foldable mobile phone 1 may be provided with various electronic components, which are exemplarily described below with reference to the accompanying drawings.

[0047] Figure 2 The exemplary structure of the foldable mobile phone 1 in some technical solutions is shown. Figure 2 The foldable mobile phone 1 may be provided with a first battery 101, a first circuit board 102 and a through-axis circuit board 103a. The first battery 101 supplies power to the first circuit board 102 through the through-axis circuit board 103a.

[0048] Specifically, the first battery 101 is disposed on the first housing 11. The first battery 101 can be used as a secondary battery of the foldable mobile phone 1. The first circuit board 102 is disposed on the second housing 12. The first circuit board 102 can be used as a main board of the foldable mobile phone 1.

[0049] The through-axis circuit board 103a extends from the first housing 11 to the second housing 12 via the rotating shaft 02. The through-axis circuit board 103a is provided with a battery voltage line (voltage battery, VBAT) L1a and a loop line L2a related to the first battery 101. Among them, one end a of the VBAT line L1a is electrically connected to the positive electrode P of the first battery 101 through the second circuit board 104, and the other end b is electrically connected to the first circuit board 102. One end c of the loop line L2a is electrically connected to the negative electrode N of the first battery 101 through the second circuit board 104, and the other end d is electrically connected to the first circuit board 102.

[0050] When the first battery 101 is discharged, the current flows from the positive electrode P of the first battery 101, sequentially through the second circuit board 104, the VBAT trace L1a of the through-axis circuit board 103a, and then reaches the first circuit board 102. Then, the current flows from the first circuit board 102, sequentially through the loop trace L2a of the through-axis circuit board 103a, the second circuit board 104, and then flows back to the negative electrode N of the first battery 101. Thus, the first battery 101 supplies power to the first circuit board 102.

[0051] In addition to the VBAT line L1a and the loop line L2a, other lines may be provided in the through-axis circuit board 103a, for example, a voltage bus (VBUS) for external charging, data transmission, etc.

[0052] However, due to the limitation of the internal space of the folding mobile phone 1, the width of the through-axis circuit board 103a is limited, and each wiring needs to occupy a certain space. Therefore, the width of the VBAT wiring L1a and the loop wiring L2a in the through-axis circuit board 103a is difficult to increase, resulting in a large discharge path impedance of the first battery 101. For example, the ground impedance of the first battery 101 is difficult to drop below 10 milliohms, and usually exceeds 50 milliohms. When the impedance of the VBAT wiring L1a is superimposed, the impedance of the entire discharge path is as high as 100 milliohms. When the folding mobile phone 1 works in a high current scenario, if the discharge path impedance of the first battery 101 is too large, the voltage of the first battery 101 will drop significantly, thereby affecting the voltage stabilization effect of the folding mobile phone 1. Among them, the high current scenario can include application scenarios such as fast charging, fast data transmission or mobile games.

[0053] In order to solve the above problems, the folding mobile phone 1 of the embodiment of the present application also includes a conductive connector connected between the first battery and the first circuit board, and the current can flow back from the first circuit board to the negative electrode of the first battery through the conductive connector, rather than from the first circuit board to the negative electrode of the first battery through the through-axis circuit board. In this way, the width of the loop line will not be limited by the through-axis circuit board, and the loop line can be set as wide as possible. At the same time, there is no need to set a loop line in the through-axis circuit board, so there is enough space to arrange the VBAT line, and the VBAT line can also be set as wide as possible, thereby effectively reducing the discharge path impedance of the first battery.

[0054] FIG. 3A to FIG. 3C The schematic diagram of the structure of the foldable mobile phone 1 in the embodiment of the present application is shown. Figure 3A and Figure 3B All of them are back views of the foldable mobile phone 1. Figure 3C For foldable phone 1 Figure 3B The sectional view of the AA section in the figure. For easy observation, Figure 3A The dotted line in FIG. 1 shows the portion of the conductive connecting member 10 that is blocked by the rotating shaft 02. Figure 3B The rotating shaft 02 and the through-shaft circuit board 103 are not shown. Figure 3C The axis of rotation 02 is shown.

[0055] refer to FIG. 3A to FIG. 3C The foldable mobile phone 1 includes a housing 01, a conductive connector 10, a first battery 101, a first circuit board 102 and a through-axis circuit board 103 (as an example of a connecting circuit board).

[0056] The housing 01 may include a first housing 11 and a second housing 12. The first housing 11 and the second housing 12 are located in different areas. For example, in this embodiment, along the Y-axis direction, the first housing 11 and the second housing 12 may be respectively arranged on opposite sides of the rotating shaft 02 and rotatably connected by the rotating shaft 02. For another example, in other embodiments, the first housing 11 and the second housing 12 may also be two independent parts that are not physically connected to each other, and this application does not limit this.

[0057] The first battery 101 and the first circuit board 102 are respectively arranged in different areas of the housing 01. For example, the first battery 101 can be arranged in the first housing 11, and the first circuit board 102 can be arranged in the second housing 12. Among them, the first battery 101 is a rectangular block, which is used to provide power to the functional devices (for example, the first circuit board 102) in the folding mobile phone 1. Exemplarily, the first battery 101 can be a secondary battery of the folding mobile phone 1. It can be understood that the folding mobile phone 1 can also include a second battery as the main battery of the folding mobile phone 1. The second battery is arranged in the second housing 12, which is used to provide power to the functional devices (for example, the first circuit board 102) in the folding mobile phone 1, thereby improving the battery life of the folding mobile phone 1.

[0058] The first circuit board 102 may also be in the shape of a rectangular block. Exemplarily, the first circuit board 102 may be the mainboard of the folding mobile phone 1. Devices such as a processor, a memory, and a communication module may be integrated on the first circuit board 102. The memory and the communication module are electrically connected to the processor respectively, the memory is used to store instructions and data, and the communication module can realize wireless communications such as 3G / 4G / 5G of the folding mobile phone 1, and can also realize wireless communications such as wireless local area networks (WLAN), Bluetooth (BT) and near field communication (NFC) of the mobile phone. It can be understood that the devices on the first circuit board 102 are not limited to the above, and electronic devices that can realize other performances of the folding mobile phone 1 are also provided, which are not listed here one by one.

[0059] The first battery 101 can supply power to the first circuit board 102 .

[0060] Specifically, the through-axis circuit board 103 extends from the first housing 11 to the second housing 12 via the rotating shaft 02, and is used to realize the electrical connection between the positive electrode P of the first battery 101 and the first circuit board 102. The through-axis circuit board 103 can be a flexible printed circuit (FPC). The flexible printed circuit is usually made of polyimide or polyester film as a substrate, and has the characteristics of being able to be freely bent, folded and twisted, so as to better adapt to the opening and closing movement of the folding mobile phone 1.

[0061] Exemplarily, a VBAT trace L1 is provided inside the through-axis circuit board 103. A second circuit board 104 is provided in the first housing 11. The second circuit board 104 is electrically connected to the positive electrode P of the first battery 101. One end a of the VBAT trace L1 of the through-axis circuit board 103 is electrically connected to the positive electrode P of the first battery 101 through the second circuit board 104, and the other end b is electrically connected to the first circuit board 102.

[0062] Two ends of the conductive connector 10 are respectively connected to the negative electrode N of the first battery 101 and the ground terminal G of the first circuit board 102 , thereby forming a loop line L2 .

[0063] When the first battery 101 is discharged, the current flows from the positive electrode P of the first battery 101, passes through the second circuit board 104, the VBAT trace L1 of the through-axis circuit board 103 in sequence, and then reaches the first circuit board 102. Then, the current flows back from the first circuit board 102 through the conductive connector 10 to the negative electrode N of the first battery 101. Thus, the first battery 101 supplies power to the first circuit board 102.

[0064] In the above-mentioned folding mobile phone 1, the current flows back from the first circuit board 102 to the negative electrode N of the first battery 101 through the conductive connector 10, rather than from the first circuit board 102 to the negative electrode N of the first battery 101 through the through-axis circuit board 103. Therefore, the width of the loop line L2 will not be limited by the through-axis circuit board 103 and can be set as large as possible. At the same time, there is no need to set up a corresponding loop line inside the through-axis circuit board 103, thereby leaving more space for setting the VBAT line L1. Therefore, the width of the VBAT line L1 can also be set as large as possible, thereby effectively reducing the discharge path impedance of the first battery 101. For example, compared with the above-mentioned solution of setting the VBAT line L1a and the loop line L2a of the first battery 101 in the through-axis circuit board 103a, the discharge path impedance of the first battery 101 in the embodiment of the present application can be reduced from 100 milliohms to less than 30 milliohms, effectively improving the working performance of the folding mobile phone 1.

[0065] Continue reading Figure 3C In some embodiments of the present application, the conductive connector 10 includes a conductive sheet 100 , a first metal plate 110 and a second metal plate 120 .

[0066] The first metal plate 110 is electrically connected to the negative electrode N of the first battery 101. Exemplarily, the negative electrode N of the first battery 101 can be electrically connected to the first metal plate 110 through a grounding member 105 (eg, a grounding spring or a grounding screw).

[0067] The second metal plate 120 is electrically connected to the ground terminal G of the first circuit board 102 . Exemplarily, the ground terminal G of the first circuit board 102 may also be electrically connected to the second metal plate 120 through the grounding member 105 .

[0068] The conductive sheet 100 is connected between the first metal plate 110 and the second metal plate 120. Thus, a loop line L2 can be formed. In this way, during the current return process, the current can flow from the first circuit board 102, through the second metal plate 120, the conductive sheet 100 and the first metal plate 110 in sequence, and then return to the negative electrode N of the first battery 101.

[0069] Among them, since the first metal plate 110 and the second metal plate 120 have good strength, the first metal plate 110 and the second metal plate 120 can also provide certain support for the folding mobile phone 1, so that the folding mobile phone 1 can better resist external impact and pressure, thereby better protecting the internal devices of the folding mobile phone 1 (for example, the first battery 101, the first circuit board 102 and the through-axis circuit board 103, etc.).

[0070] In some embodiments of the present application, the conductive connector 10 may be made of metal. For example, the conductive sheet 100 of the conductive connector 10 may be made of steel, and the first metal plate 110 and the second metal plate 120 of the conductive connector 10 may be made of zinc alloy.

[0071] Continue reading Figure 3A In some embodiments of the present application, the orthographic projection area of ​​the conductive sheet 100 in the XY plane at least partially overlaps with the orthographic projection area of ​​the through-axis circuit board 103 in the XY plane.

[0072] In this way, the VBAT line L1 of the through-axis circuit board 103 and the loop line L2 formed by the conductive connector 10 can be made closer, that is, the discharge path of the first battery 101 is a relatively flat annular path as a whole, which can effectively weaken the electromagnetic interference of the annular magnetic field coupled by the path to the first battery 101, thereby further improving the working performance of the first battery 101.

[0073] In some embodiments of the present application, the conductive sheet 100 and the first metal plate 110 and the second metal plate 120 can be fixed and electrically connected by any one or more of welding, fastener connection, or clamping. The present application does not limit this, as long as the two ends of the conductive sheet 100 can be fixed and electrically connected to the first metal plate 110 and the second metal plate 120, respectively. The following is an exemplary introduction in sequence.

[0074] In some feasible solutions, the conductive sheet 100 and the first metal plate 110 are fixed and electrically connected by welding.

[0075] For example, Figure 4A FIG. 1 shows an exemplary fixing method 1 of the conductive sheet 100 in the first metal plate 110 in the embodiment of the present application. Figure 4A The conductive sheet 100 and the first metal plate 110 and the second metal plate 120 can be welded by brazing. A metal brazing material 130A is provided between one end of the conductive sheet 100 and the first metal plate 110, so that the conductive sheet 100, the first metal plate 110, and the second metal plate 120 are connected to each other.

[0076] Alternatively, in other alternative implementations, the conductive sheet 100 and the first metal plate 110 and the second metal plate 120 may be welded by fusion welding, pressure welding, etc., and this application does not impose any specific limitation.

[0077] In some other feasible solutions, the conductive sheet 100 and the first metal plate 110 are fixed by fasteners.

[0078] For example, Figure 4B FIG. 2 shows an exemplary fixing method 2 of the conductive sheet 100 in the first metal plate 110 in the embodiment of the present application. Figure 4B , the conductive sheet 100 and the first metal plate 110 are fixedly connected by a fastener 130B. The fastener 130B may be a metal screw. A first hole 131B is provided on the conductive sheet 100, and a second through hole 132B is provided on the first metal plate 110. The positions of the first hole 131B and the second hole 132B correspond to each other. The inner walls of the first hole 131B and the second hole 132B are threaded structures. The screw of the metal screw is passed through the first hole 131B and the second hole 132B, thereby achieving the fixation and electrical connection between the conductive sheet 100 and the first metal plate 110.

[0079] In some other feasible solutions, the conductive sheet 100 and the first metal plate 110 are fixed and electrically connected by snapping.

[0080] For example, Figure 4C FIG. 3 shows an exemplary fixing method 3 of the conductive sheet 100 in the first metal plate 110 in the embodiment of the present application. Figure 4C The conductive sheet 100 is provided with a through hole 131C, and a metal bump 132C is provided on the surface of the first metal plate 110 facing the conductive sheet 100. The metal bump 132C is provided in the through hole 131C, and the outer wall of the metal bump 132C is interference-fitted with the inside of the through hole 131C, so that the conductive sheet 100 and the first metal plate 110 can be fixed and electrically connected.

[0081] Alternatively, in other alternative implementations, a hole may be provided on the surface of the first metal plate 110 facing the conductive sheet 100, a metal bump may be provided on the surface of the conductive sheet 100 facing the first metal plate 110, and the metal bump on the conductive sheet 100 may be interference fit with the hole on the first metal plate 110, so that the conductive sheet 100 and the first metal plate 110 may be electrically connected, and the present application does not impose any restrictions on this.

[0082] It can be understood that the above embodiments are only part of the implementation methods of fixing and electrically connecting the conductive sheet 100 and the first metal plate 110 in the present application, and other implementation methods that can achieve fixation and electrical connection between the conductive sheet 100 and the first metal plate 110 are within the protection scope of the present application.

[0083] In addition, it can be understood that the implementation method of fixing and electrically connecting the conductive sheet 100 and the second metal plate 120 is substantially the same as the implementation method of fixing and electrically connecting the conductive sheet 100 and the first metal plate 110 mentioned above. Therefore, reference can be made to the above description of the implementation method of fixing and electrically connecting the conductive sheet 100 and the first metal plate 110, and no further details will be given here.

[0084] In some embodiments of the present application, the conductive sheet 100 can be bent around an axis extending along the X-axis direction to better adapt to the opening and closing movement of the foldable mobile phone 1.

[0085] Specifically, Figure 5 FIG. 1 shows an exemplary structure of the conductive sheet 100 in an embodiment of the present application. Figure 5 , the conductive sheet 100 is a hollow structure.

[0086] In some embodiments, the conductive sheet 100 is provided with at least one long strip through hole 141 extending along the X-axis direction to form a hollow structure. The at least one long strip through hole 141 is arranged at intervals along the Y-axis direction and is arranged along the Z-axis direction ( Figure 5 The long strip-shaped through hole 141 can reduce the rigidity of the conductive sheet 100 in the Y-axis direction to improve the bendability of the conductive sheet 100 around an axis parallel to the X-axis direction, thereby adapting to the opening and closing movement of the foldable mobile phone 1.

[0087] In some implementations, the length of each long strip through hole 141 may be the same or different, and this application does not impose any specific limitation on this.

[0088] Continue reading Figure 5 In some implementations, the long strip through hole 141 may be a rectangular hole, that is, the cross-sectional shape of the long strip through hole 141 parallel to the plane where the conductive sheet 100 is located is a rectangle. However, the present application is not limited thereto, and in other alternative implementations, the long strip through hole 141 may also be other shapes.

[0089] For example, FIG. 6A to FIG. 6D Several exemplary structures of the long strip-shaped through holes 141 in the embodiments of the present application are shown.

[0090] refer to Fig. 6A Combined with Figure 5 In some other alternative implementations, the elongated through hole 141 may be an elliptical hole. That is, the cross-sectional shape of the elongated through hole 141 parallel to the plane where the conductive sheet 100 is located is an ellipse. The major axis of the ellipse is parallel to the X-axis direction, and the minor axis of the ellipse is parallel to the Y-axis direction, so as to improve the bendability of the conductive sheet 100 around the axis parallel to the X-axis direction.

[0091] refer to Figure 6B Combined with Figure 5 In some other alternative implementations, the elongated through hole 141 may be a racetrack-shaped hole. That is, the cross-sectional shape of the elongated through hole 141 parallel to the plane where the conductive sheet 100 is located is a racetrack shape. Among them, the boundary of the racetrack-shaped elongated through hole 141 includes a first semicircle 1411A, a rectangle 1412A, and a second semicircle 1413A arranged and connected in sequence along the same axis parallel to the X-axis direction. In the Y-axis direction, the sizes of the first semicircle 1411A, the rectangle 1412A, and the second semicircle 1413A are equal. The boundaries of the first semicircle 1411A, the rectangle 1412A, and the second semicircle 1413A are tangent and smoothly transitioned. By setting the elongated through hole 141 to a runway shape, on the one hand, the bendability of the conductive sheet 100 around an axis parallel to the X-axis direction is ensured. Secondly, the circular structures at both ends of the elongated through hole 141 (for example, the first semicircle 1411A and the second semicircle 1413A) can avoid cracks at both ends of the conductive sheet 100 along the X-axis direction when bending.

[0092] refer to Figure 6C Combined with Figure 5In some other alternative implementations, the elongated through hole 141 may be a dumbbell-shaped hole. That is, the cross-sectional shape of the elongated through hole 141 parallel to the plane where the conductive sheet 100 is located is dumbbell-shaped. Among them, the boundary of the dumbbell-shaped elongated through hole 141 includes a first runway-shaped 1411B, a rectangle 1412B, and a second runway-shaped 1413B arranged and connected in sequence along the same axis parallel to the X-axis direction. In the direction in the Y-axis direction, the dimensions on the first runway-shaped 1411B and the second runway-shaped 1413B are greater than the dimensions of the rectangle 1412B. The boundaries of the first runway-shaped 1411B, the rectangle 1412B, and the second runway-shaped 1413B are smoothly transitioned. The track structures at both ends of the above-mentioned long strip through hole 141 (for example, the first track shape 1411B and the second track shape 1413B) are set to a larger size to improve the bendability of the conductive sheet 100 around an axis parallel to the X-axis direction, while avoiding cracks at both ends of the conductive sheet 100 along the X-axis direction when bending.

[0093] refer to Fig.6D Combined with Figure 5 In some other alternative implementations, the elongated through hole 141 may be a runway dumbbell compound hole. That is, the cross-sectional shape of the elongated through hole 141 parallel to the plane where the conductive sheet 100 is located is a runway dumbbell compound shape. Among them, the elongated through hole 141 of the runway dumbbell compound shape includes a first runway shape 1411C, a rectangle 1412C, and a second runway shape 1413C arranged and connected in sequence along the X-axis direction. Along the Y-axis direction, one side of the first runway shape 1411C, the rectangle 1412C, and the second runway shape 1413C are flush, and on the other side, the size of the first runway shape 1411C and the second runway shape 1413C is larger than the size of the rectangle 1412C. The boundaries of the first runway shape 1411C, the rectangle 1412C, and the second runway shape 1413C are smoothly transitioned.

[0098] refer to Figure 7B In some other implementations, the hollow area 140 may also include a plurality of (e.g., two, three, or four) elongated through holes 142A and circular through holes 142B. The elongated through holes 142A and the circular through holes 142B are alternately arranged along the X-axis direction. For example, the elongated through holes 142A may be rectangular holes, racetrack-shaped holes, elliptical holes, or dumbbell-shaped holes, etc. For details, please refer to the above Figures 5 to 6D And the related descriptions are not repeated here.
