Description

Technical Field

[0001] The present application relates to the field of electronic technology, and in particular to a flexible circuit board, a battery, an electronic device, and a battery assembly method. Background Art

[0002] With the increasing demand for thinner and lighter electronic devices such as tablets and mobile phones, controlling the thickness of electronic devices has become a key research and development direction in the industry. Excessive thickness of electronic devices will make them fail to meet the demand for thinness and lightness.

[0003] The battery's flexible printed circuit board, cut from a base material, is used to electrically connect to the motherboard, transmitting power and battery status signals. While the thickness of the flexible printed circuit board occupies space within the electronic device, reducing the thickness of the electronic device can also reduce the thickness of the electronic device, enabling it to meet the demand for thinner and lighter devices.

[0004] However, current flexible circuit boards for batteries cannot achieve both thickness and substrate utilization. Summary of the Invention

[0005] The present invention provides a flexible circuit board, a battery, an electronic device, and a battery assembly method. The flexible circuit board can balance thickness and substrate utilization, and its substrate utilization is improved when the thickness is reduced.

[0006] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

[0007] In a first aspect, an embodiment of the present application provides a flexible circuit board. The flexible circuit board includes a first plate portion and a second plate portion. The first plate portion includes a first end and a second end arranged back to back in a first direction, and the first direction is perpendicular to the thickness direction of the first plate portion. The second plate portion is a flexible structure. The first end of the second plate portion is fixed to the second end of the first plate portion, and the second end of the second plate portion is provided with a first electrical connection portion. The second end of the second plate portion extends from the first end of the second plate portion to one side of the first plate portion in the second direction. The second direction is perpendicular to the first direction and the thickness direction of the first plate portion. In the thickness direction of the first plate portion, the second plate portion and the first plate portion do not overlap, that is, the orthographic projections of the first plate portion and the second plate portion along the thickness direction do not overlap.

[0008] In related art, the second plate portion of a flexible circuit board is bent 180° in a first direction to the surface side of the first plate portion (i.e., one side in the thickness direction of the first plate portion) and then stacked to form a double-layer structure, thereby increasing the thickness of the flexible circuit board. Before the second plate portion is bent, the first and second plate portions of the flexible circuit board are arranged in the first direction. In order to obtain the flexible circuit board before bending, the substrate needs to be cut. Because the first plate portion of the flexible circuit board before bending extends in the first direction, and the second plate portion and the first plate portion are also arranged in the first direction, when cutting the flexible circuit board from the substrate, the substrate cut in the first direction is larger in size, while the substrate cut in the second direction is smaller in size, resulting in low substrate utilization.

[0009] In this flexible circuit board, the second plate portion and the first plate portion are not stacked in the thickness direction of the first plate portion, resulting in a single-layer structure with a lower thickness than that of the related art. At the same time, the first end of the second plate portion is fixed to the second end of the first plate portion, and the second end of the second plate portion extends from the first end of the second plate portion to one side of the first plate portion in the second direction. It can be seen that in this embodiment, the second plate portion does not continue to extend along the first direction and be arranged with the first plate portion in the first direction, but extends to one side of the first plate portion in the second direction perpendicular to the first direction, which is conducive to balancing the size of the substrate cut in the first direction and the size of the substrate cut in the second direction, thereby improving the utilization rate of the substrate. It can be seen that the flexible circuit board provided by this embodiment improves the utilization rate of the substrate while reducing the thickness.

[0010] As a non-limiting embodiment, the first plate portion is configured as a strip, the first direction is a length direction of the first plate portion, and the second direction is a width direction of the first plate portion.

[0011] In this embodiment, when the first plate portion is configured as an elongated strip and the first direction is the lengthwise direction of the first plate portion, the low substrate utilization rate of the related art is more pronounced. Based on this, the above-mentioned design scheme of extending the second end of the second plate portion to one side of the first plate portion in the second direction can further improve the substrate utilization rate, and the improvement effect of the low substrate utilization rate is more significant.

[0012] As a non-limiting embodiment, the second end of the second plate portion extends a first distance along a first orientation in the first direction, then bends and extends a second distance in the second direction, and then bends and extends a third distance in the second orientation in the first direction. The third distance is greater than the first distance. The first orientation and the second orientation are opposite, and the first orientation is the orientation in which the first end of the first plate portion points toward the second end.

[0013] This embodiment provides a specific implementation scheme in which the second end of the second plate portion extends to one side of the first plate portion in the second direction. The second end of the second plate portion first extends a first distance along the first direction of the first direction, then bends and extends a second distance in the second direction, and then extends in the second direction of the first direction, roughly forming a U-shape with uneven heights on the left and right. Because the second direction is opposite to the first direction, the second end of the second plate portion is equivalent to extending in the first direction and then bending back and extending in the opposite direction of the first direction. When the third distance is greater than the first distance, plus the second distance extended in the second direction, it can be extended to one side of the first plate portion in the second direction. Combined with the above analysis, it can be seen that when the second end of the second plate portion extends to one side of the first plate portion in the second direction, it is beneficial to balance the size of the substrate cut in the first direction and the size of the substrate cut in the second direction, thereby improving the utilization rate of the substrate.

[0014] In a second aspect, embodiments of the present application provide a battery. The battery comprises a battery body and the flexible circuit board provided in any one of the first aspects. The thickness direction of the first plate portion of the flexible circuit board is aligned with the thickness direction of the battery body, and the first end of the first plate portion is electrically connected to the battery body. The second plate portion of the flexible circuit board extends to one side of the battery body.

[0015] It is understandable that, except for separate descriptions, the beneficial effects of the battery provided by the embodiment of the second aspect can be found in the relevant description of the flexible circuit board in the first aspect, and will not be repeated here.

[0016] Based on the aforementioned analysis of the flexible circuit board, it can be seen that the second plate portion and the first plate portion are not stacked in the thickness direction of the first plate portion, resulting in a single-layer flexible circuit board. When the thickness direction of the first plate portion of the flexible circuit board is the same as the thickness direction of the battery body (i.e., the thickness direction of the battery), the thickness of the single-layer flexible circuit board is distributed in the thickness direction of the battery. Compared to the related art solution of a double-layer flexible circuit board with a thickness distributed in the thickness direction of the battery, the single-layer flexible circuit board has the advantage of reducing the thickness of the battery at the flexible circuit board.

[0017] It should be noted that the second plate portion of the flexible circuit board extends to one side of the battery body, so that the flexible circuit board is electrically connected to the main board arranged on one side of the battery body through the first electrical connection portion arranged at the second end of the second plate portion.

[0018] In a third aspect, embodiments of the present application provide an electronic device. The electronic device includes a mainboard and a battery according to any one of the second aspects. A second electrical connection portion is provided on the mainboard surface. The mainboard is disposed on one side of the battery body, and a second end of the second board portion of the flexible printed circuit board of the battery extends to the mainboard surface. The second board portion is electrically connected to the second electrical connection portion via the first electrical connection portion on the second board portion.

[0019] It is understood that, except for separate descriptions, the beneficial effects of the electronic device provided by the embodiment of the third aspect can be found in the relevant description of the battery in the second aspect, and will not be repeated here. In electronic devices with lightweight and thin requirements, the thickness direction of the battery body is also the thickness direction of the electronic device. In this electronic device, the thickness of the single-layer flexible circuit board is distributed in the thickness direction of the battery, which can reduce the space occupied by the flexible circuit board in the thickness direction of the electronic device, helping to meet the lightweight and thin requirements of the electronic device.

[0020] The second end of the second board portion of the flexible circuit board extends to the board surface side of the main board located on one side of the battery body, and is opposite to the board surface of the main board, so that the first electrical connection portion of the second end of the second board portion and the second electrical connection portion on the board surface side of the main board can be opposite to each other to achieve electrical connection.

[0021] As a non-limiting embodiment, the electronic device further includes a pressure plate. The portion of the second plate portion extending from the surface of the mainboard is a deformable region. The first electrical connection portion is disposed in the deformable region. The pressure plate is attached to a surface of the deformable region facing away from the mainboard. The pressure plate is secured to the mainboard via a fixing member.

[0022] It can be understood that when the easily deformed area arches toward the motherboard, if the side of the easily deformed area facing away from the motherboard is a screen, it is easy for the screen to be topped up, resulting in reliability problems such as white spots on the screen; if the side of the easily deformed area facing away from the motherboard is a back cover, it is easy for the cover to be topped up, resulting in the appearance problem of bulging in the corresponding area of ​​the back cover.

[0023] Based on this, in this embodiment, a pressure plate is placed against the surface of the easily deformable area facing away from the mainboard, and a fixing member is used to secure the pressure plate to the mainboard. This allows a force to be applied to the pressure plate in the thickness direction toward the easily deformable area. This force causes the pressure plate to adhere to the surface of the easily deformable area, flattening it. This resolves reliability and appearance issues such as white spots on the screen caused by the easily deformable area bulging away from the mainboard.

[0024] In a fourth aspect, an embodiment of the present application provides a battery assembly method for assembling a battery in an electronic device. The electronic device has a battery position and a motherboard located on one side of the battery position. The assembly method includes: when the motherboard is assembled to one side of the battery position and the battery is in the current position, obtaining a first position of the battery's flexible circuit board and a second position of the motherboard; the first position is used to represent the position of the first electrical connection portion of the flexible circuit board; the second position is used to represent the position of the second electrical connection portion of the motherboard; based on the first position and the second position, assembling the battery to a target position of the battery position, the target position being a position where the first electrical connection portion and the second electrical connection portion correspond; and electrically connecting the first electrical connection portion and the second electrical connection portion.

[0025] Related assembly methods employ a center alignment algorithm for battery assembly, aligning the centerline of the battery body with the centerline of the battery slot. This method uses the positions on the battery body and the battery slot as reference positions for battery assembly. This can lead to the accumulation of material and assembly tolerances, resulting in misalignment between the first electrical connector on the flexible printed circuit board and the second electrical connector on the mainboard.

[0026] It should be noted that when the first electrical connection part of the battery and the second electrical connection part of the mainboard are misaligned, if the first electrical connection part of the battery and the second electrical connection part of the mainboard are forcibly electrically connected, the flexible circuit board may experience the following two situations: First, it may be arched due to redundancy, resulting in reliability problems such as white spots on the screen or appearance problems such as bulging in the corresponding area of ​​the back cover; Second, it may be torn or the electrical connection may be loose due to pulling, thereby reducing the reliability of the electrical connection between the battery and the mainboard.

[0027] In this embodiment, during battery assembly, the first position of the battery's flexible printed circuit board is used to indicate the position of the first electrical connection, while the second position of the main board is used to indicate the position of the second electrical connection. These positions are used as reference positions for assembly. Because the first position is the position on the flexible printed circuit board where the first electrical connection is located, and the second position is the position on the main board where the second electrical connection is located, compared to solutions that use structures other than the flexible printed circuit board (such as the centerline of the battery body in related assembly methods) to indicate the position of the first electrical connection, or structures other than the main board (such as the centerline of the battery position in related assembly methods) to indicate the position of the second electrical connection, the dimensional chain is interrupted, and no material tolerances of the battery position or the battery body are introduced, or assembly tolerances between the battery position and the battery body, or assembly tolerances between the battery body and the flexible printed circuit board are introduced. This allows for more accurate representation of the positions of the first and second electrical connections.

[0028] Based on this, compared to related assembly methods, using the first position of the battery's flexible circuit board and the second position of the mainboard as reference positions during battery assembly can reduce the impact of the aforementioned tolerances (such as the incoming material tolerances of the battery slot, the incoming material tolerances of the battery body, the assembly tolerances between the battery slot and the battery body, and the assembly tolerances between the battery body and the flexible circuit board) on the misalignment between the first and second electrical connections. This can thereby improve the misalignment between the first electrical connection on the flexible circuit board and the second electrical connection on the mainboard, ensuring alignment. When the first and second electrical connections correspond, electrically connecting the first and second electrical connections can alleviate bending or pulling of the flexible circuit board, thereby resolving reliability issues such as white spots on the screen caused by bending of the flexible circuit board or appearance issues caused by bending of the corresponding area of ​​the back cover. It can also address issues such as tearing or poor contact caused by bending of the flexible circuit board, thereby improving the reliability of the electrical connection between the battery and the mainboard.

[0029] As a non-limiting embodiment, the battery assembly method is used to assemble a battery in an electronic device as described in any one of the third aspects. The target position is a position where the first electrical connection portion and the second electrical connection portion correspond to each other in the first direction.

[0030] It should be noted that, for a battery having a flexible circuit board with the aforementioned double-layer structure, since the second board portion of the flexible circuit board is bent in the first direction to the board surface side of the first board portion for stacking, even if the battery is assembled using the aforementioned related assembly method and the first electrical connection portion and the second electrical connection portion are misaligned in the first direction, the position of the first electrical connection portion in the first direction can be adjusted by adjusting the position of the second board portion relative to the first board portion in the first direction, thereby improving the misalignment.

[0031] With respect to the battery in the electronic device described in any one of the third aspects, because the flexible printed circuit board used is the single-layer flexible printed circuit board described in any one of the first aspects, it is not possible to adjust the position of the first electrical connection portion in the first direction by adjusting the position of the second board portion relative to the first board portion in the first direction. Based on this, the assembly of the battery in the electronic device described in any one of the third aspects is suitable for using this assembly method to improve the misalignment between the first and second electrical connection portions in the first direction.

[0032] As a non-limiting embodiment, when the current position is the position corresponding to the battery position in the second direction, the above-mentioned assembling the battery to the target position of the battery position according to the first position and the second position includes:

[0033] Determine the actual distance between the first position and the second position in the first direction; obtain the designed distance between the first position and the second position in the first direction;

[0034] Assemble the batteries to the target position based on the actual spacing and the designed spacing. If the actual spacing is not equal to the designed spacing, the batteries are assembled from their current positions to the target positions of the battery positions. The batteries are moved in a first direction by a target movement amount, wherein the movement direction is determined based on the magnitude relationship between the actual spacing and the designed spacing, and the target movement amount is determined based on the absolute value of the difference between the actual spacing and the designed spacing. If the actual spacing is equal to the designed spacing, the batteries are assembled from their current positions to the target positions of the battery positions. The batteries are not moved in the first direction.

[0035] It should be noted that, when the current position is the position corresponding to the battery position in the second direction, whether the actual spacing is the same as the designed spacing can indicate whether the first electrical connection portion and the second electrical connection portion are misaligned in the first direction.

[0036] The actual spacing is not equal to the designed spacing, indicating that the first and second electrical connectors are misaligned in the first direction. The relationship between the actual spacing and the designed spacing can indicate the direction of misalignment between the first and second electrical connectors in the first direction. Moving the battery in the direction opposite to the misalignment (i.e., the movement direction) can reduce the misalignment between the first and second electrical connectors in the first direction, allowing them to align in the first direction. The absolute value of the difference between the actual spacing and the designed spacing can indicate the amount of misalignment between the first and second electrical connectors in the first direction. This misalignment is equal to the required movement of the battery in the first direction required to avoid misalignment between the first and second electrical connectors in the first direction. Therefore, in this embodiment, the target movement is determined based on the absolute value of the difference between the actual spacing and the designed spacing, which is equivalent to determining the target movement based on the required movement, thus facilitating alignment of the first and second electrical connectors in the first direction. Therefore, when assembling the battery from its current position to its target position, moving the battery in the first direction by the target movement along the aforementioned movement direction can facilitate assembly to the target position where the first and second electrical connectors align in the first direction.

[0037] The actual spacing is equal to the designed spacing, indicating that the first electrical connection portion and the second electrical connection portion are not misaligned in the first direction. Based on this, in this embodiment, during the process of assembling the battery to the target position, the battery is kept from moving in the first direction, thereby maintaining the first electrical connection portion and the second electrical connection portion in the first direction without misalignment, and the battery is assembled to the target position where the first electrical connection portion and the second electrical connection portion correspond in the first direction.

[0038] It can be understood that when the first electrical connection portion and the second electrical connection portion correspond to each other in the first direction, the aforementioned pulling or arching phenomenon is less likely to occur when the first electrical connection portion and the second electrical connection portion are electrically connected.

[0039] As a non-limiting example, when the actual spacing is greater than the designed spacing, it indicates that the first electrical connection portion is offset relative to the second electrical connection portion in the first direction toward a first offset orientation, i.e., the offset orientation of the first electrical connection portion and the second electrical connection portion in the first direction is the first offset orientation, where the first offset orientation is one of the first orientation and the second orientation in the first direction. The first electrical connection portion needs to be moved in a first movement orientation opposite to the first offset orientation, i.e., the movement orientation is the first movement orientation, where the first movement orientation is the other of the first orientation and the second orientation in the first direction.

[0040] The target movement is the smaller of the first movable amount and the required movement. The first movable amount is the movement that the battery position can provide to the battery in the first movement direction. The required movement is the absolute value of the difference between the actual spacing and the designed spacing. The target movement is the smaller of the first movable amount and the required movement, and is divided into the following three cases:

[0041] First, when the required movement amount is greater than the first movable amount (the smaller value is the first movable amount), it indicates that the first movable amount is insufficient to provide the required movement amount, and the battery can only move along the first movable amount at most, that is, the target movement amount is the first movable amount.

[0042] Second, when the required movement amount is less than the first movable amount (the smaller value is the required movement amount), it indicates that the first movable amount is sufficient to provide the required movement amount, and the battery can move the required movement amount, that is, the target movement amount is the required movement amount, that is, the absolute value of the difference between the actual spacing and the designed spacing.

[0043] Third, when the required movement amount is equal to the first movable amount (the smaller value is the required movement amount or the first movable amount), it indicates that the first movable amount just provides the required movement amount, and the battery can move the required movement amount, that is, the target movement amount is the required movement amount or the first movable amount, that is, the absolute value of the difference between the actual spacing and the designed spacing.

[0044] In this embodiment, the target movement amount is the smaller value between the required movement amount and the first movable amount, so that the battery will not be moved out of the battery position and cannot be assembled.

[0045] When the actual spacing is smaller than the designed spacing, the first electrical connection part is offset in the first direction toward the first misalignment direction, that is, the misalignment direction of the first electrical connection part and the second electrical connection part in the first direction is the second misalignment direction, and the second misalignment direction is the other of the first direction and the second direction in the first direction. The first electrical connection part needs to be moved to a second movement direction opposite to the second misalignment direction, that is, the movement direction is the second movement direction, and the second movement direction is one of the first direction and the second direction in the first direction. The target movement amount is the smaller value of the second movable amount and the required movement amount, and the second movable amount is the movement amount that the battery position can provide to the battery in the second movement direction. The target movement amount is the smaller value of the second movable amount and the required movement amount, and the description of the three cases where the momentum is the smaller value of the first movable amount and the required movement amount can be adaptively referred to.

[0046] As a non-limiting example, when the centerline of the battery position in the first direction and the centerline of the battery body in the first direction are collinear, the first movable amount and the second movable amount are (AB) / 2. Where A is the accommodation dimension of the battery position in the first direction, and B is the dimension of the battery body in the first direction.

[0047] Typically, electronic devices are designed to meet the following conditions: When the first and second electrical connectors are not misaligned in the first direction, the centerline of the battery holder in the first direction and the centerline of the battery body in the first direction are collinear. This allows the battery to be assembled into the battery holder in a relatively centered position, making the weight of the electronic device more balanced in the first direction. When the centerline of the battery holder in the first direction and the centerline of the battery body in the first direction are collinear, the single-sided clearance between the battery holder and the battery body is (AB) / 2. Based on this, the amount of movement that the battery holder can provide to the battery body in the first and second orientations of the first direction is (AB) / 2, i.e., the first and second movable amounts are (AB) / 2. For example, (AB) / 2 is greater than 0.1 cm.

[0048] As a non-limiting embodiment, the first position is an edge of a side of the second plate portion facing away from the first plate portion in the first direction.

[0049] It should be noted that the first end of the second plate portion is referred to as the fixed end because it secures the second end of the first plate portion. Prior to the first electrical connection portion of the second end of the second plate portion being electrically connected to the second electrical connection portion, the second end is referred to as the free end. Because the second plate portion is a flexible structure, the closer the second plate portion is to the free end in the first direction, the more easily it changes position, making it less suitable for use as the first position.

[0050] Because the second end of the second plate portion extends to one side of the first plate portion in the second direction, the first plate portion can represent the position of the second end (i.e., the free end) of the second plate portion in the first direction. Based on this, this embodiment selects the first position as the edge of the side of the second plate portion facing away from the first plate portion in the first direction, which is equivalent to selecting the position of the second plate portion farthest from the free end in the first direction as the first position. Compared with other positions of the second plate portion, this position is less likely to change and has little effect on the misalignment of the first electrical connection portion and the second electrical connection portion in the first direction. In addition, selecting the edge of the side of the second plate portion facing away from the first plate portion in the first direction as the first position helps to obtain the actual spacing between the first position and the second position in the first direction during the assembly process of the battery, thereby helping to make the first electrical connection portion and the second electrical connection portion correspond to each other in the first direction.

[0051] As a non-limiting embodiment, the second position is a side edge of the copper leakage area of ​​the mainboard in the first direction.

[0052] It should be noted that because the copper leakage area of ​​the motherboard has a distinct color difference from other areas of the motherboard (the motherboard is typically green), it is easily distinguished during image recognition. Based on this, in this embodiment, the edge of the copper leakage area of ​​the motherboard is used as the second location, making it easier to identify during image recognition, thereby facilitating the rapid and accurate capture of the second location. Furthermore, selecting a side edge of the copper leakage area in the first direction facilitates determining the actual spacing between the first and second locations in the first direction during battery assembly, thereby facilitating alignment of the first electrical connection portion with the second electrical connection portion in the first direction.

[0053] In a fifth aspect, an embodiment of the present application also provides another battery assembly method for assembling a battery in an electronic device provided in the third aspect, wherein the electronic device has a battery position. The assembly method includes: moving the battery to the battery position of the electronic device, and extending the flexible circuit board of the battery to the board surface side of the mainboard to electrically connect to the mainboard through the flexible circuit board, wherein the area where the flexible circuit board extends to the board surface side of the mainboard is the easily deformable area; placing a pressure plate on the side of the easily deformable area facing away from the mainboard; using a cover plate to push the pressure plate toward the side where the easily deformable area is located so that the easily deformable area is flattened on the surface of the mainboard; a pressure head is provided on the side of the cover plate facing the pressure plate, the pressure head contacts the pressure plate before the cover plate, and the position where the pressure head contacts the pressure plate is located between two fixed positions, and the fixed positions are used to set fixing parts; when the cover plate pushes the pressure plate to flatten the easily deformable area, a fixing part is set at each of the two fixed positions to fix the pressure plate to the mainboard.

[0054] In the related art, the cover plate is not provided with a pressure head. When two fixing parts are used to fix the easily deformed area, the easily deformed area between the two fixing positions is prone to arch back toward the mainboard, thereby causing reliability problems such as white spots on the screen or appearance problems such as bulging in the corresponding area of ​​the back cover.

[0055] In this assembly method, the pressing head contacts and presses down the pressing plate before the cover plate. As a result, when two fixing members are used to secure the easily deformable area, the pressing head holds the area between the two fixing positions, preventing it from arching. This prevents reliability and appearance issues such as white spots on the screen caused by the easily deformable area arching away from the motherboard.

[0056] As a non-limiting example, the indenter has a Rockwell hardness of 50 to 60 HR. In this case, the indenter makes soft contact with the pressure plate, and the pressure plate is less likely to be damaged during downward pressure. Furthermore, an indenter with a Rockwell hardness of 50 to 60 HR exhibits soft material and easily deforms during downward pressure, allowing the cover plate to contact the pressure plate, thereby pushing the pressure plate to flatten the easily deformed area on the mainboard surface.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0081] In order to make the purpose, technical solutions and advantages of this application more clear, this application is further described in detail below with reference to the accompanying drawings and embodiments.

[0082] The present invention provides an electronic device. For example, the electronic device may be a mobile phone, tablet computer, desktop computer, laptop computer, handheld computer, notebook computer, ultra-mobile personal computer (UMPC), netbook computer, cellular phone, personal digital assistant (PDA), augmented reality (AR) or virtual reality (VR) device, or other battery-containing device. The present invention does not impose any particular restrictions on the specific form of the electronic device. The following description uses a tablet computer as an example.

[0083] For example, see Figure 1 and Figure 2 , Figure 1 This is a structural diagram of an electronic device 000 provided in an embodiment of the present application. Figure 2 for Figure 1 The schematic diagram of the structural decomposition of the electronic device 000 is shown.

[0084] In this embodiment, the electronic device 000 is a tablet computer, including a screen 001, a back cover 002, Figure 2 The displayed mid-board 003, camera module 004, battery 005 and main board 006. It is understandable that Figure 1 and Figure 2 Only some components of the electronic device 000 are schematically shown, and the actual shapes, sizes, positions and structures of these components are not affected by the present invention. Figure 1 and Figure 2 Furthermore, in other embodiments of the present application, the electronic device 000 may include more or fewer components than shown in the figure, or combine some components, or separate some components, or arrange the components differently.

[0085] These components are introduced below.

[0086] Screen 001 is used to display images, videos, etc. Screen 001 can be a flexible display screen or a rigid display screen. For example, the display screen can be an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode (AMOLED) display screen, a mini organic light-emitting diode (OLED) display screen, a micro organic light-emitting diode (OLED) display screen, a micro organic light-emitting diode (OLED) display screen, a quantum dot light-emitting diode (QLED) display screen, or a liquid crystal display (LCD) display screen.

[0087] For the convenience of the following description, an XYZ coordinate system is established, defining the length direction of the electronic device 000 as the X-axis direction, the width direction of the electronic device 000 as the Y-axis direction, and the thickness direction of the electronic device 000 as the Z-axis direction. It should be noted that the coordinate system setting of the electronic device 000 can be flexibly set according to actual needs.

[0088] The back cover 002 , also called the battery cover, is used to protect the internal electronic components of the electronic device 000 . The back cover 002 includes a back plate 021 and a frame 022 .

[0089] The back plate 021 is located on one side of the back side of the screen 001 and is stacked with the screen 001 in the Z-axis direction.

[0090] Frame 022 surrounds the sides of screen 001 and back panel 021 and is fixedly connected to screen 001 and back panel 021, respectively. For example, frame 022 can be fixedly connected to screen 001 using adhesive. For example, frame 022 and back panel 021 are integrally molded. In other embodiments, frame 022 can also be integrally molded with mid panel 003.

[0091] It can be understood that the screen 001, the back panel 021, and the frame 022 together enclose a storage space for the electronic device 000, so that functional components of the electronic device 000 can be placed in the storage space, such as Figure 2 The functional components shown, such as the camera module 004, battery 005, and mainboard 006, simultaneously seal and protect the functional components located in the accommodation space.

[0092] Middle plate 003 is used to mount the functional components of electronic device 000. It is located between screen 001 and back plate 021 and is fixed to the inner surface of frame 022. Middle plate 003 serves as the structural "frame" of electronic device 000, mounting its functional components such as camera module 004, battery 005, and motherboard 006.

[0093] Camera module 004 is used to capture photos / videos. There can be one or more camera modules 004, though only one front-facing camera is shown in the figure. Camera module 004 is fixed to the surface of middle plate 003 facing screen 001, specifically near the center of the long side of middle plate 003 (the center of the edge extending along the X-axis). "Near" means that the distance between this location and the center of the long side of middle plate 003 is relatively small, and this distance can be adjusted as needed. Of course, in other embodiments, camera module 004 can be fixed to other locations on middle plate 003, for example, to the surface of middle plate 003 facing back plate 021; or to one of the four corners of middle plate 003. For example, camera module 004 can be fixed and supported on middle plate 003 by means of threaded connections, clamping connections, welding, or the like, with the light-entering surface of camera module 004 facing screen 001. A light-transmitting area 011 is provided at a position of the screen 001 facing the camera module 004 so that light can enter the camera module 004 through the light-transmitting area 011 , thereby realizing the shooting function.

[0094] The battery 005 is used to supply power to the functional components of the electronic device 000 that require power. Figure 2 In the figure, a battery slot 031 is provided on the middle plate 003 to accommodate the battery 005. Battery slot 031 can be a hole in the middle plate 003, spaced on the negative Y-axis side of the camera module 004 to facilitate installation of the main plate 006 between the battery 005 and the camera module 004. The battery 005 is installed in battery slot 031, stacked with the screen 001 and back plate 021 in the Z-axis direction. To illustrate battery slot 031, the battery 005 and middle plate 003 are disassembled along the Z-axis in the figure.

[0095] Of course, in some other embodiments, the battery position 031 can also be set at other positions of the middle plate 003, so that the battery 005 can be installed at other positions of the middle plate 003. For example, in the Y-axis direction, the battery position 031 can be set between the main board 006 and the camera module 004, so that the battery 005 is located between the main board 006 and the camera module 004.

[0096] Mainboard 006 is a key carrier for functional components, used to electrically connect functional components integrated and / or not integrated on mainboard 006. For example, mainboard 006 can be electrically connected to a power management module (not shown) integrated on mainboard 006 and a battery 005 not integrated on mainboard 006, thereby electrically connecting the power management module and battery 005. In this way, battery 005 can transmit power to the power management module via mainboard 006, thereby providing power to the functional components of electronic device 000 that require power.

[0097] Figure 2 In the figure, a motherboard position 032 is provided on the middle plate 003 to accommodate the motherboard 006. Motherboard position 032 can be a hole in the middle plate 003, located on one side of the battery 005 in the Y-axis direction, specifically on the positive side of the Y-axis. The middle plate 003 and the motherboard 006 are not separated in the Z-axis direction in the figure, so the position of motherboard position 032 can be roughly referenced to the position of motherboard 006. Motherboard 006 is located in motherboard position 032 on the middle plate 003, generally (except for some specific features) on the side of the battery 005 in the Y-axis direction near the camera module 004, and is stacked with the screen 001 and back plate 021 in the Z-axis direction. Of course, in other embodiments, motherboard 006 can also be fixed to other locations on the middle plate 003, such as generally on the side of the battery 005 in the X-axis direction.

[0098] It should be noted that with the increasing demand for thinner and lighter electronic devices 000, controlling the thickness of electronic devices 000 has become a key research and development direction in the industry. If the thickness of electronic devices 000 is too large, the electronic devices 000 will not meet the thinner and lighter requirements. Figure 2 In the embodiment, different parts of the battery 005 occupy different thickness spaces of the electronic device 000, which are determined by the dimensions of each part in the Z-axis direction. In order to meet the requirements of thinning and lightening the electronic device 000, it is necessary to control the dimensions of each part of the battery 005 in the Z-axis direction.

[0099] In the related art, the size of the flexible circuit board of the battery 005 in the Z-axis direction is large, which makes the thickness of the battery 005 at the flexible circuit board, and thus makes the electronic device 000 not meet the requirements of lightness and thinness. Based on this, the embodiment of the present application provides Figure 2 The thickness of the battery 005 at the flexible circuit board is reduced by reducing the thickness of the flexible circuit board it contains, thereby reducing the thickness of the electronic device 000 to meet the requirements of the electronic device 000 for being thin and light. Figure 3 The battery 005 provided in the embodiment of the present application is described.

[0100] For example, please refer to Figure 3 , Figure 3 for Figure 2 Schematic diagram of the structure of the battery 005. The battery 005 includes a battery body 100 and a flexible circuit board 200.

[0101] The battery body 100 can be understood as the battery 005 placed Figure 2 The battery part of the battery position 031 shown (excluding the flexible circuit board 200). The battery body 100 includes but is not limited to the battery cell group 110. For example, Figure 3 In the embodiment, the battery body 100 may further include a protection circuit board 120 and the like.

[0102] The cell group 110 is the core part of the battery 005, responsible for the storage and release of electrical energy. It is usually composed of a positive electrode, a negative electrode, an electrolyte, and a separator, and can generate current through chemical reactions. In order to increase the power of the battery 005, in some embodiments, the cell group 110 can be formed by combining multiple cells 111. For example, Figure 3 In the embodiment, the battery cell group 110 includes two battery cells 111 arranged side by side in the X-axis direction. Of course, in other embodiments, the battery cells 111 may also be arranged side by side in other directions, which is not limited in this embodiment of the present application.

[0103] The cell group 110 is roughly a plate-like structure in appearance. The so-called plate-like structure refers to a structure whose length and width are much greater than its thickness. For a plate-like structure, the surface with length and width is the plate surface of the plate-like structure, and the thickness direction of the plate-like structure is perpendicular to the plate surface of the plate-like structure. The length direction of the cell group 110 shown in the figure is the X-axis direction, the width direction is the Y-axis direction, and the thickness direction is the Z-axis direction. In the embodiment of the present application, the two side surfaces of the cell group 110 facing each other in the X-axis direction are respectively referred to as the left side and right side of the cell group 110, the two side surfaces of the cell group 110 facing each other in the Y-axis direction are respectively referred to as the upper side and lower side of the cell group 110, and the two plate surfaces of the cell group 110 facing each other in the Z-axis direction are respectively referred to as the upper plate surface and the lower plate surface of the cell group 110. Similar terms related to "plate" in the embodiment of the present application can be understood with reference to the explanation here. It should be noted that the thickness direction of the battery 005 is determined by the thickness direction of the battery body 100. In this embodiment, the thickness direction of the battery body 100 is the Z-axis direction, so the thickness direction of the battery 005 is also the Z-axis direction.

[0104] The protection circuit board 120 is a crucial component of the battery 005 and is electrically connected to the cell pack 110. It monitors the cell pack 110's voltage and charge / discharge current through electronic circuitry, and controls the current loop in abnormal situations to protect the cell pack 110 from damage. Key functions include overcharge protection, over-discharge protection, overcurrent protection, short-circuit protection, and temperature protection, preventing the battery 005 from damage or safety incidents caused by extreme conditions. The protection circuit board 120 typically includes components such as a control IC, MOS switches, resistors, capacitors, an NTC temperature sensor, and an ID memory, used to monitor the battery 005's status and control protective actions.

[0105] Figure 3 In the figure, the protection circuit board 120 covers the lower surface of the cell group 110 (the side facing away from the upper surface of the cell group 110 shown in the figure), the left side of the cell group 110, and the right side of the cell group 110. The protection circuit board 120 also extends to the side facing the upper side of the cell group 110, that is, to the side of the cell group 110 in the positive direction of the Y axis. In this embodiment of the application, the portion of the protection circuit board 120 that extends to the side of the cell group 110 in the Y axis direction is referred to as the extension portion 121. The thickness direction of the extension portion 121 is also in the Z axis direction.

[0106] The flexible circuit board 200 is a circuit board with bendable characteristics, which is used to connect the battery 005 electrically. Figure 2 Specifically, the flexible circuit board 200 extends from one side of the extension portion 121 in the positive direction of the Z axis to the other side of the extension portion 121 in the positive direction of the Y axis, so as to facilitate the connection with the main board 006. Figure 2 The main board 006 located on one side of the battery position 031 in the positive direction of the Y axis is electrically connected, thereby realizing the electrical connection between the battery 005 and the main board 006.

[0107] When the battery 005 is electrically connected to the main board 006, on the one hand, the battery 005 can release the electrical energy stored in the battery cell group 110 to the main board 006 through the flexible circuit board 200, and the main board 006 can also store electrical energy in the battery cell group 110 of the battery 005 through the flexible circuit board 200. On the other hand, the battery 005 can transmit the signal of the battery 005 status monitored by the protection circuit board 120 to the main board 006 through the flexible circuit board 200, and the main board 006 can also transmit the control signal to the protection circuit board 120 of the battery 005 through the flexible circuit board 200.

[0108] Figure 3In the figure, since the thickness of the flexible circuit board 200 is in the Z-axis direction, the thickness of the flexible circuit board 200 is the dimension of the flexible circuit board 200 in the Z-axis direction, which affects the thickness of the battery 005 at the flexible circuit board 200. Therefore, by reducing the thickness of the flexible circuit board 200, the thickness of the battery 005 at the flexible circuit board 200 can be reduced, thereby reducing the thickness space occupied by the battery 005 at the flexible circuit board 200 in the thickness of the electronic device 000, thereby meeting the demand for a thinner and lighter electronic device 000.

[0109] In the related art, the flexible circuit board 200 is a double-layer structure, which results in a relatively large thickness of the flexible circuit board 200, and the thickness of the battery 005 at the flexible circuit board 200, thereby making the electronic device 000 not meet the requirements of being lightweight and thin. Based on this, the embodiment of the present application provides Figure 3 The flexible circuit board 200 in the embodiment adopts a single-layer structure to reduce the thickness of the flexible circuit board 200, thereby reducing the thickness of the battery 005 at the flexible circuit board 200, meeting the requirements of the electronic device 000 for being thin and light. Figures 4 and 5 Conduct comparative analysis.

[0110] For example, please refer to Figure 4 , Figure 4 This is a schematic diagram of the structure of a flexible circuit board 200 provided in an embodiment of the present application. The flexible circuit board 200 can be applied to Figure 3 The battery 005 shown in FIG. The battery 005 having the flexible circuit board 200 can be used in a face-up structure (the battery is mounted on the side of the middle plate facing the back cover), a flip-chip structure (the battery is mounted on the side of the middle plate facing the screen), a high-power battery (the battery power can be increased by increasing or decreasing the battery dimensions in the X-axis and Y-axis directions without increasing the thickness), and an electronic device 000 that requires a thinner and lighter structure.

[0111] The flexible circuit board 200 is used to electrically connect the first device and the second device, thereby realizing signal transmission between the first device and the second device. Figure 3 In the case of the battery 005 shown, the first device can be Figure 3 In the battery body 100, the second device can be Figure 2 Of course, in some other embodiments, the flexible circuit board 200 can also be used in other scenarios to achieve electrical connection between the first device and the second device in the other scenarios. Figure 3 The battery 005 shown is used as an example for explanation.

[0112] The flexible circuit board 200 includes a first board portion 210 and a second board portion 220 .

[0113] The flexible circuit board 200 is a circuit board with bendable properties. It should be noted that having bendable properties does not require the flexible circuit board 200 to be entirely flexible. In specific implementations, at least a portion of the flexible circuit board 200 is flexible, which enables the flexible circuit board 200 to have bendable properties.

[0114] for example, Figure 4 In the embodiment, the first plate portion 210 is a rigid structure, and the second plate portion 220 is a flexible structure, thereby making the flexible circuit board 200 bendable. In this case, the flexible circuit board 200 can be cut from a panel formed by splicing a rigid substrate and a flexible substrate. Of course, in other embodiments, the entire flexible circuit board 200 is a flexible structure, which is not limited in this embodiment of the present application.

[0115] The first plate portion 210 and the second plate portion 220 are described below respectively.

[0116] First, the first plate portion 210 will be described.

[0117] The first plate portion 210 includes a first end 210a and a second end 210b that are disposed in opposite directions in a first direction (e.g., the X-axis direction in the figure). The first direction in the figure is the X-axis direction, which is perpendicular to the thickness direction of the first plate portion 210 (e.g., the Z-axis direction in the figure). Unless otherwise specified, the subsequent embodiments will be described with the X-axis direction replacing the first direction and the Z-axis direction replacing the thickness direction of the first plate portion 210. The first plate portion 210 is a structure for the flexible circuit board 200 to electrically connect to the first device, which is Figure 3 The battery main body 100 in.

[0118] Next, the second plate portion 220 will be described.

[0119] The thickness direction of the second plate portion 220 is approximately in the Z-axis direction. It should be noted that because the second plate portion 220 is a flexible structure, it is easy for the second plate portion 220 to move relative to the first plate portion 210. As a result, the thickness direction of the second plate portion 220 is not necessarily in the Z-axis direction, but is approximately in the Z-axis direction.

[0120] The second plate portion 220 includes a first end 220 a and a second end 220 b .

[0121] The first end 220 a of the second plate portion 220 fixes the second end 210 b of the first plate portion 210 (specifically, it may fix the end surface of the second end 210 b of the first plate portion 210 in the X-axis direction).

[0122] The second end 220b of the second board portion 220 is provided with a first electrical connection portion (such as the BTB connector male socket 230 shown in the figure) for connecting Figure 2 Motherboard 006 in. Figure 4FIG shows the BTB connector male socket 230 from the rear view of the second end 220b of the second plate portion 220. Figure 2 The main board 006 has a second electrical connection portion (such as a BTB connector socket 061) electrically connected to the first electrical connection portion.

[0123] The second end 220 b of the second plate portion 220 extends from the first end 220 a of the second plate portion 220 to one side of the first plate portion 210 in a second direction perpendicular to the first direction and the thickness direction of the first plate portion 210 . Figure 4 In the figure, when the first direction is the X-axis direction and the thickness direction of the first plate portion 210 is the Z-axis direction, the second direction is the Y-axis direction in the figure. Unless otherwise specified, the subsequent embodiments will be described using the Y-axis direction instead of the second direction. It should be noted that one side of the first plate portion 210 in the Y-axis direction is the area directly opposite the side surface of the first plate portion 210 in the Y-axis direction (the area between the dotted lines W1 and W2 in the figure), that is, the area corresponding to the projection path of the orthographic projection of the side surface along the Y-axis direction. Figure 4 In the embodiment, the second end 220b of the second plate portion 220 specifically extends to one side of the first plate portion 210 in the positive direction of the Y axis.

[0124] In the Z-axis direction, the second plate portion 220 and the first plate portion 210 do not overlap. In other words, the orthographic projections of the second plate portion 220 and the first plate portion 210 in the Z-axis direction do not overlap. In this case, the second plate portion 220 and the first plate portion 210 are not stacked in the Z-axis direction, resulting in a single-layer structure in the Z-axis for the flexible circuit board 200. However, in related art, the flexible circuit board 200 has a double-layer structure in the Z-axis direction.

[0125] Please refer to Figure 5 , Figure 5 A structural diagram of a flexible circuit board 200 provided in the related art. Figure 5 In the flexible circuit board 200 shown, before the second plate portion 220 is bent (the dotted line in the figure indicates the state before bending), the first end 210a and the second end 210b of the first plate portion 210 and the first end 220a and the second end 220b of the second plate portion 220 are all arranged back to back in the X-axis direction.

[0126] Because the second plate portion 220 is a flexible structure with bendable properties, the second plate portion 220 can be bent 180° in the X-axis direction to the board surface side of the first plate portion 210 (that is, one side of the first plate portion 210 in the Z-axis direction) for stacking (the bent state is indicated by a solid line in the figure), so that the flexible circuit board 200 has a double-layer structure in the Z-axis direction.

[0127] Before the second plate portion 220 is bent, the second end 220b of the second plate portion 220 extends away from the first plate portion 210 in the X-axis direction, which is the direction in which the first plate portion 210 extends. With the first plate portion 210 and the second plate portion 220 arranged sequentially in the X-axis direction, the flexible circuit board 200 occupies a relatively large space in the X-axis direction. Therefore, by bending the second plate portion 220, the space occupied by the flexible circuit board 200 in the X-axis direction can be reduced. However, bending the second plate portion 220 results in a double-layer structure of the flexible circuit board 200, which increases the thickness of the flexible circuit board 200.

[0128] It can be seen that compared with Figure 5 As for the double-layer flexible circuit board 200 shown in FIG. Figure 4 The thickness of the flexible circuit board 200 of the single-layer structure is reduced. According to statistics, this allows the flexible circuit board 200 to have a thickness gain of 0.25 mm.

[0129] In the Figure 4 The flexible circuit board 200 of the single-layer structure shown is applied to Figure 3 The battery 005 shown is assembled to Figure 2 When using the electronic device 000 shown in FIG. Figure 6 , Figure 6 for Figure 2 The diagram shows a plan view of the middle board 003 and some functional components installed thereon in the electronic device 000. Figure 6 Among them, some functional components installed on the middle plate 003 include camera module 004, battery 005 and main board 006, etc.

[0130] To electrically connect the battery body 100, the first plate portion 210 extends to one side of the battery cell group 110 in the positive Y-axis direction. It is aligned with the extension portion 121, which is also on the same side of the battery cell group 110 in the positive Y-axis direction, in the Z-axis direction. Furthermore, the first plate portion 210 and the extension portion 121 face each other. The opposing surfaces of the first plate portion 210 and the extension portion 121 are electrically connected, thereby electrically connecting the flexible circuit board 200 to the battery body 100. Exemplarily, the electrical connection between the flexible circuit board 200 and the extension portion 121 includes, but is not limited to, welding or plugging.

[0131] It should be noted that Figure 6 In the embodiment, the first plate portion 210 is located on one side of the cell group 110 in the positive direction of the Y axis. Compared to a solution where the first plate portion 210 is located on the surface side of the cell group 110, this helps reduce the thickness of the battery 005 at the cell group 110. Of course, in other embodiments, the first plate portion 210 may also be located on the surface side of the cell group 110, and this embodiment of the application is not limited thereto.

[0132] In order to electrically connect to the main board 006, the second end 220b of the second board portion 220 extends to one side of the battery body 100 in the positive direction of the Y axis, opposite to the board surface of the main board 006 on the same side of the battery body 100 in the positive direction of the Y axis, and the second end 220b of the second board portion 220 is engaged with the BTB connector female socket 061 on the board surface side of the main board 006 through the BTB connector male socket 230 provided thereon to achieve electrical connection, thereby achieving electrical connection between the flexible circuit board 200 and the main board 006.

[0133] Figure 6 In the embodiment, the thickness direction of the first plate portion 210 and the battery body 100 (determined by the thickness direction of the battery cell group 110) is the Z-axis direction. In this case, the thickness of the flexible circuit board 200 affects the thickness of the battery 005 at the flexible circuit board 200. As the thickness of the flexible circuit board 200 decreases, the thickness of the battery 005 at the flexible circuit board 200 decreases. When the thickness of the battery 005 at the flexible circuit board 200 decreases, the contact of the battery 005 with the flexible circuit board 200 can be reduced. Figure 2 The thickness of the electronic device 000 shown in FIG2 is reduced, thereby meeting the thin and light requirements of the electronic device 000. In addition, since the second plate portion 220 of the flexible circuit board 200 extends to one side of the first plate portion 210 in the Y-axis direction, the thickness of the electronic device 000 can be reduced. Figure 2 The space occupied by the electronic device 000 in the X-axis direction is shown.

[0134] In addition, compared to Figure 5 As for the flexible circuit board 200 shown, Figure 4 The flexible circuit board 200 shown has a higher utilization rate of the panel.

[0135] Specifically, please refer to Figure 7 , Figure 7 for Figure 4 The flexible circuit board 200 and Figure 5 The diagram shows the corresponding cutting positions of the flexible circuit board 200 on the panel.

[0136] in, Figure 7 (a) is indicated by a dotted line. Figure 5 The flexible circuit board 200 shown corresponds to the cutting position on the panel. Figure 7 The dotted line in (b) indicates Figure 4 The flexible circuit board 200 is shown at the corresponding cutting position on the panel.

[0137] because Figure 5 The first board portion 210 and the second board portion 220 of the flexible circuit board 200 are arranged in sequence in the X-axis direction, and the flexible circuit board 200 occupies a larger space in the X-axis direction. Figure 7In (a), cut from the corresponding cutting position on the puzzle board Figure 5 When the flexible circuit board 200 is cut as shown, the size of the panels cut in the X-axis direction is larger and the size of the panels cut in the Y-axis direction is smaller, resulting in a lower utilization rate of the panels, which is obviously contrary to the demand for cost control.

[0138] and Figure 4 In the flexible circuit board 200 shown, the first end 220a of the second board portion 220 is fixed to the second end 210b of the first board portion 210, and the second end 220b of the second board portion 220 extends from the first end 220a of the second board portion 220 to one side of the first board portion 210 in the Y-axis direction. Figure 4 In the embodiment shown, the second plate portion 220 does not continue to extend from the second end 210b of the first plate portion 210 along the X-axis direction and is arranged with the first plate portion 210 in the X-axis direction, but extends to one side of the first plate portion 210 in the Y-axis direction, so as not to occupy a large space in the X-axis direction. Based on this, Figure 7 In (b), cut from the corresponding cutting position on the puzzle board Figure 4 The flexible circuit board 200 shown in the figure has a more balanced size of panels cut in the X-axis direction and the Y-axis direction, thereby improving the utilization rate of the panels. According to statistics, this can make the flexible circuit board 200 have a cost benefit of 1.5 RMB.

[0139] As a non-limiting example, please refer to Figure 4 The first plate portion 210 is configured as a long strip. In this case, the X-axis direction may be the length direction of the first plate portion 210 , and the Y-axis direction may be the width direction of the first plate portion 210 .

[0140] It should be noted that, when the first plate portion 210 is configured as a long strip and the X-axis direction is the length direction of the first plate portion 210, the Figure 5 The flexible printed circuit board 200 shown in FIG. The design scheme of extending the second end 220b of the second board portion 220 from the first end 220a of the second board portion 220 to one side of the first board portion 210 in the Y-axis direction can further improve the utilization rate of the board, and the improvement effect of the low utilization rate of the board is more significant.

[0141] In addition, combined Figure 6The length direction of the first plate portion 210 is the same as the length direction of the battery body 100. By rationally utilizing the length direction of the battery body 100 to extend the long strip of the first plate portion 210, the internal space utilization rate of the battery 005 relative to the electronic device 000 can be improved. Of course, in other embodiments, the length direction of the first plate portion 210 can also be the same as the width direction of the battery body 100. In this case, the second plate portion 220 extends to one side of the battery body 100 in the X-axis direction, and the main board 006 is located on one side of the battery body 100 in the X-axis direction, so as to facilitate the electrical connection between the second plate portion 220 and the main board 006.

[0142] As a non-limiting example, please refer to Figure 4 To achieve the extension of the second end 220b of the second plate portion 220 from the first end 220a of the second plate portion 220 to one side of the first plate portion 210 in the Y-axis direction, the second end 220b of the second plate portion 220 is extended along a first direction in the first direction (as shown in the positive X-axis direction) by a first distance D1 to form a first sub-plate portion, then bent and extended along the Y-axis by a second distance D2 to form a second sub-plate portion, and then bent and extended along a second direction in the first direction (as shown in the negative X-axis direction) by a third distance D3 to form a third sub-plate portion. The second plate portion 220 is generally U-shaped, with uneven heights on both sides. The third distance D3 is greater than the first distance D1. The first and second directions are opposite, with the first direction being the direction from the first end of the first plate portion 210 to the second end.

[0143] Figure 4 In the embodiment, the direction in which the first end 210a of the first plate portion 210 points toward the second end 210b is the positive direction of the X-axis, that is, the first direction of the first direction is the positive direction of the X-axis. It is understood that in other embodiments, the first direction of the first direction is the positive direction of the X-axis, and the second direction of the first direction is the negative direction of the X-axis. The following embodiments are described using the example of the first direction of the first direction being the positive direction of the X-axis and the second direction of the first direction being the negative direction of the X-axis.

[0144] In this embodiment, because the positive direction of the X-axis and the negative direction of the X-axis are opposite, the second end 220b of the second plate portion 220 is equivalent to extending in the positive direction of the X-axis and then extending back in the negative direction of the X-axis. When the third distance D3 is greater than the first distance D1, plus the second distance D2 extending in the Y-axis direction, it can be extended to one side of the first plate portion 210 in the Y-axis direction. Combined with the above analysis, it can be seen that when the second end 220b of the second plate portion 220 extends to one side of the first plate portion 210 in the Y-axis direction, it is beneficial to balance the size of the panels cut in the X-axis direction and the size of the panels cut in the Y-axis direction, thereby improving the utilization rate of the panels.

[0145] Of course, in some other embodiments, the second end 220b of the second plate portion 220 can also extend from the first end of the first plate portion 210 to one side of the first plate portion 210 in the Y-axis direction by other extension methods, and is not limited to Figure 4 For example, Figure 8 Two optional embodiments are provided.

[0146] For example, please refer to Figure 8 , Figure 8 Schematic diagrams of the planar structures of some other flexible circuit boards 200 provided in the embodiments of the present application.

[0147] Figure 8 In (a), the first end 220a of the second plate portion 220 is fixed to the second end 210b of the first plate portion 210 (specifically, it is fixed to the side surface of the second end 210b of the first plate portion 210 in the Y-axis direction). The second end 220b of the second plate portion 220 is bent and extended a certain distance from the first end 220a of the second plate portion 220 along the Y-axis direction, and then bent and extended a certain distance in the negative direction of the X-axis. The second plate portion 220 is generally L-shaped.

[0148] Figure 8 In (b), the first end 220a of the second plate portion 220 fixes the second end 210b of the first plate portion 210 (specifically, fixes the side surface of the second end 210b of the first plate portion 210 in the Y-axis direction), and the second end 220b of the second plate portion 220 gradually extends from the first end 220a of the second plate portion 220 in the negative direction of the X-axis.

[0149] Figure 8 The two embodiments provided are merely illustrative. In a specific implementation, the second end 220b of the second plate portion 220 may also have more extension methods, as long as it extends to one side of the first plate portion 210 in the Y-axis direction.

[0150] Below Figure 2 The assembly method of the battery 005 in the electronic device 000 is illustrated as an example.

[0151] For example, please refer to Figure 9 , Figure 9 A structural assembly diagram provided for related assembly methods.

[0152] This assembly method utilizes a center alignment algorithm to assemble battery 005 into battery slot 031 of electronic device 000. Specifically, the centerline of battery body 100 (e.g., centerline O2 of battery body 100 in the X-axis direction, as shown) is aligned with the centerline of battery slot 031 (e.g., centerline O1 of battery slot 031 in the X-axis direction, as shown) to assemble battery 005 into battery slot 031 of electronic device 000. This assembly method uses the positions on battery body 100 and battery slot 031 as reference positions for assembly of battery 005, which can lead to the accumulation of material tolerances and assembly tolerances. This can cause misalignment between BTB connector male receptacle 230 and BTB connector female receptacle 061 when battery 005 is moved to battery slot 031.

[0153] for example, Figure 9 In the embodiment, the tolerance accumulated in the X-axis direction causes the BTB connector male socket 230 and the BTB connector female socket 061 to be misaligned in the X-axis direction. Figure 9 (a) shows the case where the BTB connector male socket 230 is misaligned relative to the BTB connector female socket 061 in the negative direction of the X-axis. In this case, the flexible circuit board 200 is redundant in the X-axis direction; Figure 9 (b) shows the situation where the BTB connector male socket 230 is misaligned relative to the BTB connector female socket 061 in the positive direction of the X-axis. In this case, the flexible circuit board 200 is insufficient in the X-axis direction.

[0154] It should be noted that Figure 9 In the case where the BTB connector male socket 230 and the BTB connector female socket 061 of the mainboard 006 are misaligned in the X-axis direction, if the BTB connector male socket 230 of the battery 005 and the BTB connector female socket 061 of the mainboard 006 are forcibly electrically connected, the flexible circuit board 200 may experience the following two situations:

[0155] First, corresponding to Figure 9 (a) in the Figure 10 As shown in (a), the flexible circuit board 200 is redundant in the X-axis direction, causing the flexible circuit board 200 to arch back toward the main board 006. Figure 2 Because the side of the flexible circuit board 200 facing away from the mainboard 006 is the screen 001, the bulging of the flexible circuit board 200 facing away from the mainboard 006 can easily lead to reliability issues such as white spots on the screen 001. In other embodiments, the side of the flexible circuit board 200 facing away from the mainboard 006 can also be the back cover 002. In this case, the bulging of the flexible circuit board 200 facing away from the mainboard 006 can easily lead to bulging in the corresponding area of ​​the back cover 002.

[0156] Second, corresponding to Figure 9 (b) in the Figure 10As shown in (b), the flexible circuit board 200 is pulled due to the insufficient length of the flexible circuit board 200 in the X-axis direction. Figure 2 When the flexible circuit board 200 is pulled, the flexible circuit board 200 may be torn or the BTB connector male socket 230 and the BTB connector female socket 061 may not be firmly fastened together, thereby reducing the reliability of the electrical connection between the battery 005 and the mainboard 006.

[0157] It should be noted that in some other embodiments, the assembly method may also align the centerline of the battery body 100 in the Y-axis direction with the centerline of the battery position 031 in the Y-axis direction to assemble the battery 005. In this case, the aforementioned tolerance will cause the BTB connector male socket 230 and the BTB connector female socket 061 to be misaligned in the Y-axis direction. This misalignment in the Y-axis direction can also easily cause the flexible circuit board 200 to bulge or pull, thereby causing the aforementioned problem.

[0158] Based on this, in order to solve the above-mentioned problem caused by the misalignment of the BTB connector male socket 230 and the BTB connector female socket 061, which causes the flexible circuit board 200 to be arched or pulled, the embodiments of the present application provide two solutions.

[0159] First, the first solution is described.

[0160] The first solution is a new assembly method of battery 005, which can be used to achieve Figure 2 The assembly of the battery 005 in the electronic device 000 shown below. Figure 11 and Figure 12 Provide explanation.

[0161] For example, please refer to Figure 11 , Figure 11 A schematic flow chart of a method for assembling a battery 005 provided in an embodiment of the present application is applied to a mechanical device for assembling the battery 005. Figure 12 for Figure 11 The structural assembly diagram corresponding to the assembly method shown Figure 1 . Figure 11 The illustrated assembly method includes the following steps S101 to S104 .

[0162] Step S101: Install the mainboard to one side of the battery position.

[0163] For example, please refer to Figure 12 The mainboard 006 is located on one side of the battery position 031 in the Y-axis direction, specifically on the side of the positive direction of the Y-axis. Based on this, the mainboard 006 is specifically installed on the side of the battery position 031 in the positive direction of the Y-axis.

[0164] also, Figure 12 In FIG, the current position of battery 005 is the battery position indicated by the solid line, which is located on one side of battery position 031 in the Y-axis direction and at the position corresponding to battery position 031 in the Y-axis direction. Figure 12 The corresponding position of the battery position 031 in the Y-axis direction is: the position between the reference lines where the two edge lines are located in the X-axis direction, that is, the position between the reference line P1 and the reference line P2.

[0165] It should be noted that the battery being located at the position corresponding to battery position 031 in the Y-axis direction does not limit whether battery 005 is located at the positions corresponding to battery position 031 in the X-axis and Z-axis directions. For example, in some other embodiments, the current position of battery 005 may be directly at battery position 031. In this case, battery 005 is located at both the position corresponding to battery position 031 in the Y-axis direction and the position corresponding to battery position 031 in the X-axis and Z-axis directions. It can be seen that the current position of battery 005 at battery position 031 also falls under the situation where the battery is located at the position corresponding to battery position 031 in the Y-axis direction. The definition of the battery being located at the position corresponding to battery position 031 in the Y-axis direction and the position corresponding to battery position 031 in the Z-axis direction can refer to the meaning of the battery being located at the position corresponding to battery position 031 in the X-axis direction.

[0166] Furthermore, in some other embodiments, the current position of battery 005 may not be at the position corresponding to battery position 031. For example, it may not be at the position corresponding to battery position 031 in the Y-axis direction, or it may not be at the position corresponding to battery position 031 in the X-axis direction, or it may not be at the position corresponding to battery position 031 in the Z-axis direction, etc. This embodiment of the present application is not limited to this.

[0167] Step S102 , obtaining a first position of the flexible circuit board of the battery and a second position of the main board.

[0168] In a specific implementation process, in step S101, the mechanical device may include a mechanical arm for holding the battery and a camera mounted on the mechanical arm, such as a charge-coupled device (CCD) camera. When the mechanical arm of the mechanical device is moving while holding the battery, the camera continuously takes pictures. The camera's image sensor (such as CCD) takes pictures of the flexible circuit board containing the battery and the main board (such as Figure 12 Image recognition is performed on the photo corresponding to the viewing angle shown in the figure) to obtain the above-mentioned first position and second position.

[0169] The first position is used to indicate the position of the BTB connector male socket of the flexible circuit board. It should be noted that a position on the flexible circuit board that is not easily moved relative to the BTB connector male socket can be used to indicate the first position of the BTB connector male socket of the motherboard.

[0170] As a non-limiting embodiment, in order to facilitate image recognition, the first position can be selected as the edge position of a certain part on the flexible circuit board. Since the edge position has a clear boundary with the surrounding parts, it can be used as a feature for image recognition, thereby locating the first position more quickly.

[0171] for example, Figure 12 In the X-axis direction (ie, the first direction), the edge S1 of the second plate portion 220 facing away from the first plate portion 210 is the first position.

[0172] It should be noted that the first end of the second plate portion 220 is referred to as the fixed end because it secures the second end of the first plate portion 210. The second end of the second plate portion 220 is a free end until the BTB connector male receptacle 230 is electrically connected to the BTB connector female receptacle 061. Because the second plate portion 220 is flexible, the closer the second plate portion 220 is to the free end in the X-axis, the easier it is to move. Using this as a reference position during assembly increases the likelihood of misalignment between the BTB connector male receptacle 230 and the BTB connector female receptacle 061 in the X-axis, potentially preventing electrical connection between them. Therefore, the closer the second plate portion 220 is to the free end in the X-axis, the less suitable it is for use as the first position.

[0173] In this embodiment, because the second end of the second plate portion 220 extends to one side of the first plate portion 210 in the Y-axis direction, the first plate portion 210 can represent the position of the second end (free end) of the second plate portion 220 in the X-axis direction. Based on this, this embodiment selects the first position as the edge of the second plate portion 220 facing away from the first plate portion 210 in the X-axis direction. This is equivalent to selecting the position of the second plate portion 220 farthest from the free end in the X-axis direction as the first position. Compared to other positions on the second plate portion 220, this position is less prone to movement and has less impact on the misalignment of the BTB connector male receptacle 230 and the BTB connector female receptacle 061 in the X-axis direction.

[0174] Of course, in some other embodiments, the first position is not limited to the edge S1. For example, please continue to refer to Figure 12 In the case where the first board portion 210 of the flexible circuit board 200 is a rigid structure, the first position may also be a position on the first board portion 210. For example, the first position may be Figure 12 The illustrated edge S2 of the first plate portion 210 , the edge S3 of the first plate portion 210 , and so on.

[0175] The position and shape of the first plate portion 210 constructed as a rigid structure are not prone to relative changes. The position on the first plate portion 210 constructed as a rigid structure is selected to represent the first position of the BTB connector male socket 230, which is used as a reference position during assembly. This has little effect on the misalignment of the BTB connector male socket 230 and the BTB connector female socket 061 in the X-axis direction, thereby enabling electrical connection between the BTB connector male socket 230 and the BTB connector female socket 061.

[0176] It should be noted that the first position is not limited to Figure 12 The first position is shown as an example. In other embodiments, the first position may also be other positions on the flexible printed circuit board 200 .

[0177] The second position is used to represent the position of the motherboard's BTB connector socket. It should be noted that a position on the motherboard that is not easily moved relative to the BTB connector socket can be used to represent the second position of the motherboard's BTB connector socket.

[0178] As a non-limiting embodiment, in order to facilitate image recognition, the second position can be selected as the edge position of a certain part on the motherboard. Since the edge position has a clear boundary with the surrounding parts, it can be used as a feature for image recognition, thereby locating the second position more quickly. For example, the second position can be selected as the edge of the copper leakage area on the motherboard. For example, Figure 12 One side edge S4 of the two side edges of the copper leakage region 062 arranged in the X-axis direction is the second position.

[0179] Because the copper leakage area 062 of the mainboard 006 has a distinct color difference from other areas of the mainboard 006 (mainboard 006 is typically green), it is easily distinguished during image recognition. Therefore, in this embodiment, the edge of the copper leakage area 062 of the mainboard 006 is used as the second location, making it easier to identify during image recognition, thereby facilitating rapid and accurate capture of the second location.

[0180] It should be noted that the second position is not limited to Figure 12 The illustrated position is shown. In other embodiments, the second position may also be other positions on the main board 006.

[0181] Step S103: assemble the battery to a target battery position according to the first position and the second position, wherein the target battery position is a position where the male socket of the BTB connector corresponds to the female socket of the BTB connector.

[0182] Please refer to Figure 12The BTB connector male receptacle 230 and the BTB connector female receptacle 061 correspond to each other, which can mean that the BTB connector male receptacle 230 and the BTB connector female receptacle 061 correspond to each other in the X-axis direction and / or the Y-axis direction. The BTB connector male receptacle 230 and the BTB connector female receptacle 061 correspond to each other in a certain direction, which means that the BTB connector male receptacle 230 and the BTB connector female receptacle 061 are not misaligned in that direction, or the misalignment is sufficiently small that the buckling or pulling of the flexible circuit board 200 caused by the engagement of the BTB connector male receptacle 230 with the BTB connector female receptacle 061 is not obvious and is insufficient to offset the screen or back cover. The threshold of this misalignment can be set as needed.

[0183] It should be noted that if the BTB connector male receptacle 230 and the BTB connector female receptacle 061 correspond to each other in the X-axis direction and / or the Y-axis direction, they are both considered to correspond to each other. In this case, step S103 is equivalent to assembling the battery to the target position based on the first position and the second position so that the BTB connector male receptacle and the BTB connector female receptacle correspond to each other in the X-axis direction and / or the Y-axis direction.

[0184] Figure 12 In the embodiment, since the space occupied by the flexible circuit board 200 in the Y-axis direction is much smaller than the space occupied in the X-axis direction, even if the BTB connector male socket 230 and the BTB connector are misaligned in the Y-axis direction, the redundancy or insufficient length of the flexible circuit board 200 in the Y-axis direction is relatively mild, and the resulting arching or pulling phenomenon is not obvious. Therefore, in the specific implementation process, more attention is usually paid to improving the misalignment of the BTB connector male socket 230 and the BTB connector in the X-axis direction.

[0185] Based on this, as a non-limiting example, Figure 12 In the example, the target position is the position where the BTB connector male socket 230 and the BTB connector female socket 061 correspond to each other in the X-axis direction (i.e., the first direction). In this case, the above step S103 is: based on the first position and the second position, assemble the battery 005 to the target position where the BTB connector male socket 230 and the BTB connector female socket 061 correspond to each other in the X-axis direction. For example, Figure 12 In the embodiment, according to the edge S1 and the edge S4, the battery 005 is assembled to the target position where the BTB connector male socket 230 and the BTB connector female socket 061 correspond to each other in the X-axis direction.

[0186] In step S103, assembling the battery to the target position of the battery position may involve the step of moving the battery from the current position to the target position of the battery position. For example, Figure 12In the example, if the battery is located at the battery position indicated by the dashed line within the battery position 031, the BTB connector male socket 230 corresponds to the BTB connector female socket 061. Therefore, the target position can be the battery position indicated by the dashed line within the battery position 031. In this case, in step S103, the battery 005 is moved from the current position indicated by the solid line to the target position indicated by the dashed line within the battery position 031.

[0187] Depend on Figure 12 It can be seen that moving the battery 005 to the target position of the battery position 031 does not require that all components of the battery 005 be moved into the battery position 031. For example, the battery 005 may be moved to the target position of the battery position 031 by moving the main body of the battery 005 to the target position of the battery position 031 while a portion of the flexible circuit board 200 extends outside the battery position 031. In addition, assembling the battery 005 to the target position of the battery position 031 may also involve steps related to the assembly of the battery 005, such as aligning and fastening the battery 005 in the Z-axis direction and securing the battery 005, which are not limited in this embodiment of the present application.

[0188] Step S104 , fasten the BTB connector male socket and the BTB connector female socket together to achieve electrical connection.

[0189] Please combine Figure 12 When assembling the battery 005, the first position of the flexible circuit board 200 of the battery 005 is used to represent the position of the BTB connector male socket 230, and the second position of the main board 006 is used to represent the position of the BTB connector female socket 061, and these are used as reference positions for assembling the battery 005.

[0190] Compared to the scheme of characterizing the position of the BTB connector male socket 230 by other structures outside the flexible circuit board 200 (such as the center line of the battery 005 used in the relevant assembly method), and characterizing the position of the BTB connector female socket 061 by other structures outside the main board 006 (such as the center line of the battery position 031 used in the relevant assembly method), since the first position is the position on the flexible circuit board 200 where the BTB connector male socket 230 is located, and the second position is the position on the main board 006 where the BTB connector female socket 061 is located, and since the incoming material tolerance of the battery position 031, the incoming material tolerance of the battery 005 body, the assembly tolerance between the battery position 031 and the battery 005 body, and the assembly tolerance between the battery 005 body and the flexible circuit board 200 are not introduced, the first position and the second position can respectively more accurately characterize the position of the BTB connector male socket 230 and the position of the BTB connector female socket 061.

[0191] Based on this, compared with the relevant assembly method, using the first position of the flexible circuit board 200 of the battery 005 and the second position of the main board 006 as the reference positions during assembly has little effect on the misalignment of the BTB connector male socket 230 and the BTB connector female socket 061, thereby improving the misalignment of the BTB connector male socket 230 and the BTB connector female socket 061 in a certain direction or multiple directions, so that the BTB connector male socket 230 and the BTB connector female socket 061 correspond to each other in a certain direction or multiple directions. When the BTB connector male socket 230 and the BTB connector female socket 061 correspond to each other in a certain direction or multiple directions, snapping the BTB connector male socket 230 and the BTB connector female socket 061 together can improve the arching or pulling phenomenon of the flexible circuit board 200, thereby solving reliability problems such as white spots on the screen 001 caused by the arching of the flexible circuit board 200 or the appearance problem of arching of the corresponding area of ​​the back cover 002, and can also solve the problem of tearing or poor contact caused by pulling the flexible circuit board 200, thereby improving the electrical connection reliability between the battery 005 and the main board 006.

[0192] In addition, for Figure 12 In the case of assembling the battery 005 to the target position where the BTB connector male socket 230 and the BTB connector female socket 061 correspond to each other in the X-axis direction, since the BTB connector male socket 230 and the BTB connector female socket 061 correspond to each other in the X-axis direction, when the BTB connector male socket 230 and the BTB connector female socket 061 are fastened together, it is not easy for the flexible circuit board 200 to be bulged due to redundancy in the X-axis direction, or to be pulled due to insufficient length in the X-axis direction, thereby solving the problem. Figure 10 The problem described.

[0193] It should be noted that, due to Figure 5 The flexible circuit board 200 shown is a double-layer structure bent 180° in the X-axis direction. The second plate portion 220 of the flexible circuit board 200 can move relative to the first plate portion 210 in the X-axis direction. Figure 5 The battery 005 of the flexible circuit board 200 shown is Figure 9 The assembly method shown in the figure can also be used to assemble the BTB connector male socket 230 of the second board portion 220 in the X-axis direction, so that the BTB connector male socket 230 and the BTB connector female socket 061 are engaged without the flexible circuit board 200 being arched or pulled.

[0194] However, compared to Figure 5 As for the flexible circuit board 200 shown in FIG. Figure 4The flexible circuit board 200 shown is not a double-layer structure bent 180° in the X-axis direction. The second board portion 220 of the flexible circuit board 200 cannot move relative to the first board portion 210 in the X-axis direction, so the position of the BTB connector male socket 230 of the second board portion 220 in the X-axis direction cannot be adjusted. Figure 9 The relevant assembly method shown will Figure 2 When the battery 005 is moved to the battery position 031, the position of the BTB connector male socket 230 of the second plate portion 220 in the X-axis direction cannot be adjusted, and thus the misalignment of the BTB connector male socket 230 of the battery 005 and the BTB connector female socket 061 of the main board 006 in the X-axis direction cannot be improved, resulting in the inability to achieve electrical connection between the BTB connector male socket 230 of the battery 005 and the BTB connector female socket 061 of the main board 006. Based on this, Figure 2 Battery 005 is suitable for Figure 11 The assembly method shown improves the misalignment between the first electrical connection portion and the second electrical connection portion in the X-axis direction.

[0195] It should be noted that Figure 11 The assembly method of the battery 005 shown in the figure can also be used to assemble the battery 005 in other electronic devices 000, for example, in other electronic devices 000 having Figure 5 The battery 005 of the flexible circuit board 200 is assembled as shown. In this case, there is no need to adjust the position of the second board portion 220 in the X-axis direction to improve the misalignment of the BTB connector male socket 230 and the BTB connector female socket 061 in the X-axis direction.

[0196] Next, continue to combine Figure 11 and Figure 12 Taking the target position as the position where the BTB connector male socket 230 and the BTB connector female socket 061 correspond to each other in the X-axis direction as an example, step S103 is described in detail.

[0197] As a non-limiting example, please refer to Figure 11 When the current position is the position corresponding to the battery position 031 in the Y-axis direction, and the target position is the position where the BTB connector male socket 230 and the BTB connector female socket 061 correspond in the X-axis direction, step S103 may include the following steps S1031 to S1033.

[0198] Step S1031 , determining the actual distance between the first position and the second position in the X-axis direction.

[0199] The actual distance between the first position and the second position in the X-axis direction refers to the absolute value of the difference between the X coordinate of the first reference line passing through the first position along the Y-axis direction and the X coordinate of the second reference line passing through the second position along the Y-axis direction when the battery 005 moves to the current position.

[0200] Continue with Figure 12 As an example, taking the first position as edge S1 and the second position as edge S4, when the battery 005 is in the current position indicated by the solid line, the absolute value of the difference between the X coordinate of the first reference line L1 passing through the edge S1 along the Y-axis direction and the X coordinate of the second reference line L2 passing through the edge S4 along the Y-axis direction is the actual distance △L1 between the first position and the second position in the X-axis direction.

[0201] It should be noted that Figure 12 The first position and the second position in the figure are exactly the edge S1 and the edge S4 extending along the Y-axis direction. Therefore, the first reference line L1 extending along the Y-axis direction just coincides with the edge S1, and the second reference line L2 extending along the Y-axis direction just coincides with the edge S4. In some other embodiments, the first position and the second position are in other forms. For example, the first position and the second position can also be positions corresponding to two points. In this case, the first reference line passes through one of the two points along the Y-axis direction, and the second reference line passes through the other of the two points along the Y-axis direction. For another example, the first position and the second position can also be positions corresponding to two irregular shapes. In this case, the first reference line passes through a point on one of the shapes along the Y-axis direction, and the second reference line passes through a point on the other shape along the Y-axis direction.

[0202] Figure 12 In the embodiment, since it is necessary to obtain the actual spacing △L1 between the first position and the second position in the X-axis direction, when the first position is selected, the side edge S1 of the second plate portion 220 facing away from the first plate portion 210 in the X-axis direction is used as the first position; when the second position is selected, the side edge S2 of the copper leakage area 062 in the X-axis direction is used as the second position, which helps to obtain the actual spacing △L1 between the first position and the second position in the X-axis direction, thereby helping to make the BTB connector male socket 230 and the BTB connector female socket 061 correspond to each other in the X-axis direction.

[0203] Step S1032: Obtain a designed spacing between the first position and the second position in the X-axis direction.

[0204] The designed spacing between the first and second positions in the X-axis direction is the spacing between the first and second positions in the X-axis direction designed during the design phase of electronic device 000 to ensure that BTB connector male receptacle 230 and BTB connector female receptacle 061 do not misalign in the X-axis direction when battery 005 is assembled into battery position 031. This designed spacing can be determined and stored during the design phase of electronic device 000 so that it can be recalled during the execution of the assembly method.

[0205] Continue with Figure 12 For example, taking the first position as edge S1 and the second position as edge S4, to facilitate differentiation from the target position of battery 005, the battery position indicated by a dashed line outside battery position 031 is shown to illustrate battery 005 with the designed spacing. The absolute value of the difference between the X coordinate of a third reference line L3 along the Y axis passing through edge S1 of battery 005, indicated by the dashed line, and the X coordinate of a second reference line L2 along the Y axis passing through edge S4 can be understood as the designed spacing ΔL3 between the first and second positions along the X axis.

[0206] The execution order of the above steps S1031 and S1032 is not critical. Figure 12 In the example, the actual spacing △L1 and the designed spacing △L3 are explained by taking the battery position indicated by the solid line as an example, which is offset in the negative direction of the X axis relative to the battery position indicated by the dotted line outside the battery position 031. In this case, the actual spacing △L1 is greater than the designed spacing △L3. In other embodiments, such as Figure 13 As shown, the battery position indicated by the solid line can also be offset in the positive direction of the X axis relative to the battery position indicated by the dotted line outside the battery position 031. In this case, the actual spacing △L1 is smaller than the designed spacing △L3, or, as shown in FIG. Figure 14 As shown, the battery position indicated by the solid line may not be offset in the X-axis direction relative to the battery position indicated by the dotted line outside the battery position 031. In this case, the actual spacing ΔL1 is equal to the designed spacing ΔL3. This embodiment of the present application is not limited to this.

[0207] Step S1033 , assembling the batteries to the target battery positions according to the actual spacing and the designed spacing.

[0208] Depending on whether the actual spacing and the designed spacing are equal, step S1033 may be different, which will be discussed below in different cases.

[0209] First, if the actual spacing is not equal to the designed spacing, in step S1033, the battery 005 is moved along the X-axis by the target movement amount along the movement direction when it is assembled from the current position to the target position. The movement direction is determined by the size relationship between the actual spacing and the designed spacing; the target movement amount is determined by the absolute value of the difference between the actual spacing and the designed spacing.

[0210] Since the design spacing is the spacing between the first position and the second position in the X-axis direction when the BTB connector male socket 230 and the BTB connector female socket 061 are not misaligned in the X-axis direction, the actual spacing is not equal to the design spacing, which can indicate that the BTB connector male socket 230 and the BTB connector female socket 061 are misaligned in the X-axis direction.

[0211] The relationship between the actual spacing and the designed spacing can represent the misalignment direction of the BTB connector male receptacle 230 and the BTB connector female receptacle 061 in the X-axis direction. Moving the battery 005 in the direction opposite to the misalignment direction (the direction opposite to the misalignment direction is referred to as the movement direction in this embodiment of the application) can improve the misalignment of the BTB connector male receptacle 230 relative to the BTB connector female receptacle 061 in the X-axis direction, thereby causing the BTB connector male receptacle 230 and the BTB connector female receptacle 061 to align in the X-axis direction.

[0212] Based on this, in order to assemble the battery 005 to the target position where the BTB connector male socket 230 and the BTB connector female socket 061 correspond in the X-axis direction, in step S1033, the battery 005 is moved along the X-axis direction while being assembled from the current position to the target position. Because the relationship between the actual spacing and the designed spacing can represent the above-mentioned misalignment direction, and the opposite direction of the misalignment direction is the movement direction, based on this, the movement direction in this embodiment is determined based on the relationship between the actual spacing and the designed spacing.

[0213] The absolute value of the difference between the actual spacing and the designed spacing represents the amount of misalignment between the BTB connector male receptacle 230 and the BTB connector female receptacle 061 in the X-axis direction. This misalignment is equal to the required movement of the battery 005 in the X-axis direction required to prevent misalignment between the BTB connector male receptacle 230 and the BTB connector female receptacle 061. Based on this, in this embodiment, the target movement is determined based on the absolute value of the difference between the actual spacing and the designed spacing, which is equivalent to determining the target movement based on the required movement, thus facilitating alignment of the BTB connector male receptacle 230 and the BTB connector female receptacle 061 in the X-axis direction.

[0214] Continue with Figure 12 For example, Figure 12 It shows the situation where the actual spacing is larger than the designed spacing.

[0215] In the X-axis direction, the battery position indicated by the solid line is offset in the negative X-axis direction relative to the battery position indicated by the dotted line outside the battery position 031, resulting in the actual spacing being greater than the designed spacing, and the BTB connector male socket 230 is misaligned in the negative X-axis direction relative to the BTB connector female socket 061. In this case, the misalignment direction of the BTB connector male socket 230 relative to the BTB connector female socket 061 in the X-axis direction is the negative X-axis direction (i.e., the first misalignment direction is the negative X-axis direction). It can be seen that Figure 12 In the figure, the actual spacing is greater than the designed spacing, indicating that the misalignment direction is in the negative X-axis direction. To assemble battery 005 from its current position (shown by the solid line) to its target position (shown by the dashed line) within battery position 031, it must be moved in the positive X-axis direction, meaning the movement direction is in the positive X-axis direction (i.e., the first movement direction is in the positive X-axis direction).

[0216] It should be noted that the first misalignment direction is opposite to the first movement direction. The first misalignment direction is one of the first direction and the second direction in the first direction, and the first movement direction is the other of the first direction and the second direction in the first direction. Figure 12 In the example, the positive direction of the X-axis is the first orientation of the first direction, and the negative direction of the X-axis is the second orientation of the first direction. Based on this, Figure 12 The first misalignment direction is the second direction of the first direction and the first movement direction is the first direction of the first direction. In other embodiments, the first misalignment direction may be the first direction of the first direction and the first movement direction may be the second direction of the first direction.

[0217] visible, Figure 12 In the embodiment, the first misalignment direction represented by the magnitude relationship between the actual deviation and the design deviation is opposite to the first movement direction. Based on this, the movement direction can be determined based on the magnitude relationship between the actual deviation and the design deviation.

[0218] and, Figure 12 In the example, the difference between the actual and designed spacing is ΔL13 (ΔL13 in the figure is the difference between the X-coordinates of the first reference line L1 and the third reference line L3). The X-axis misalignment between the male BTB connector 230 and the female BTB connector 061 is ΔL45 (ΔL45 in the figure is the difference between the X-coordinates of the fourth reference line L4 and the fifth reference line L5). The absolute value of ΔL13 is roughly equal to the absolute value of ΔL45. Therefore, the absolute value of the difference between the actual and designed spacing represents the X-axis misalignment between the male BTB connector 230 and the female BTB connector 061, and is also the required displacement. Based on this, the target displacement ΔP (the spacing between reference lines P3 and P5) can be determined based on the absolute value of the difference between the actual and designed spacing.

[0219] In some other embodiments, such as Figure 13 As shown, Figure 13 It shows the situation where the actual spacing is smaller than the designed spacing.

[0220] In the X-axis direction, the battery position indicated by the solid line is offset in the positive direction of the X-axis relative to the battery position indicated by the dotted line outside the battery position 031, resulting in the actual spacing being greater than the designed spacing, and the BTB connector male socket 230 is misaligned in the positive direction of the X-axis relative to the BTB connector female socket 061. In this case, the misalignment direction of the BTB connector male socket 230 relative to the BTB connector female socket 061 in the X-axis direction is the positive direction of the X-axis (i.e., the second misalignment direction is the positive direction of the X-axis). It can be seen that Figure 13 In the figure, the actual spacing is smaller than the designed spacing, indicating that the misalignment direction is in the positive X-axis direction. To assemble battery 005 from its current position (shown by the solid line) to its target position (shown by the dashed line) within battery position 031, it must be moved in the negative X-axis direction, meaning that the movement direction is in the negative X-axis direction (i.e., the second movement direction is in the negative X-axis direction).

[0221] The second misaligned direction is opposite to the second moving direction, the second misaligned direction is the other of the first direction and the second moving direction, and the second moving direction is one of the first direction and the second moving direction. The second misaligned direction is opposite to the first misaligned direction, and the second moving direction is opposite to the first moving direction. Figure 13 , the positive direction of the X axis is the first orientation of the first direction, and the negative direction of the X axis is the second orientation of the first direction. Therefore, Figure 13 The second misaligned direction is the first direction of the first direction and the second moving direction is the second direction of the first direction. In other embodiments, the second misaligned direction may be the second direction of the first direction and the second moving direction may be the first direction of the first direction.

[0222] It can be seen that the second misalignment direction represented by the magnitude relationship between the actual deviation and the design deviation is opposite to the second movement direction. Based on this, the movement direction can be determined based on the magnitude relationship between the actual deviation and the design deviation.

[0223] and, Figure 13In the example, the difference between the actual and designed spacing is ΔL13 (ΔL13 in the figure is the difference between the X-coordinates of the first reference line L1 and the third reference line L3). The X-axis misalignment between the male BTB connector 230 and the female BTB connector 061 is ΔL45 (ΔL45 in the figure is the difference between the X-coordinates of the fourth reference line L4 and the fifth reference line L5). The absolute value of ΔL13 is roughly equal to the absolute value of ΔL45. Therefore, the absolute value of the difference between the actual and designed spacing represents the X-axis misalignment between the male BTB connector 230 and the female BTB connector 061, and is also the required displacement. Based on this, the target displacement ΔP (the spacing between reference lines P3 and P5) can be determined based on the absolute value of the difference between the actual and designed spacing.

[0224] Second, the actual spacing is equal to the designed spacing. In step S1033, when the battery 005 is assembled from the current position to the target position, the battery 005 does not move in the X-axis direction.

[0225] Because the design spacing is the spacing between the first position and the second position in the X-axis direction when the BTB connector male socket 230 and the BTB connector female socket 061 are not misaligned in the X-axis direction, the actual spacing is equal to the design spacing, which can indicate that the BTB connector male socket 230 and the BTB connector female socket 061 are not misaligned in the X-axis direction. Based on this, in this case, during the process of assembling the battery 005 to the target position, this embodiment keeps the battery 005 from moving in the X-axis direction, thereby maintaining the BTB connector male socket 230 and the BTB connector female socket 061 in the X-axis direction. The battery 005 is assembled to the target position where the BTB connector male socket 230 and the BTB connector female socket 061 correspond in the X-axis direction.

[0226] For example, Figure 14 As shown, Figure 14 It illustrates the situation where the actual spacing ΔL1 is equal to the designed spacing ΔL3.

[0227] In the X-axis direction, the battery position indicated by the solid line is not offset relative to the battery position indicated by the dotted line outside the battery position 031 in the X-axis direction, so that the actual spacing is equal to the designed spacing (the first reference line L1 and the third reference line L3 coincide), and the BTB connector male socket 230 is not misaligned relative to the BTB connector female socket 061 in the X-axis direction (the fourth reference line L4 and the fifth reference line L5 coincide). It can be seen that Figure 14In the example, the actual spacing is equal to the designed spacing, indicating that the BTB connector male socket 230 and the BTB connector female socket 061 are not misaligned in the X-axis direction. In this case, this embodiment maintains the position of the battery 005 in the X-axis direction and moves the battery 005 to the battery position 031, thereby assembling the battery 005 to the target position.

[0228] Figures 12 to 14 In the figure, the battery position indicated by the solid line is located on one side of the battery position 031 in the Y-axis direction and is not located in the battery position 031. Therefore, in step S1033, the battery 005 is assembled to the target position indicated by the dotted line in the battery position 031, which involves moving the battery 005 to the target position indicated by the dotted line in the battery position 031 and assembling it. Figures 12 to 13 For the embodiment shown, moving the battery 005 to the target position indicated by the dotted line in the battery position 031 involves movement in the X-axis direction, the Y-axis direction, and the Z-axis direction; Figure 14 In the embodiment shown, since the battery 005 does not move in the X-axis direction, moving the battery 005 to the target position indicated by the dotted line in the battery position 031 involves movement in the Y-axis and Z-axis directions. The embodiment of the present application does not impose any special restrictions on the specific process of moving the battery 005 to the target position indicated by the dotted line in the battery position 031. For example, Figure 12 In the figure, battery 005 can first move in the Y-axis direction, then move in the X-axis direction, and finally move in the Z-axis direction, thereby moving to the target position indicated by the dotted line in battery position 031; it can also first move in the X-axis direction, then move in the Y-axis direction, and finally move in the Z-axis direction, thereby moving to the target position indicated by the dotted line in battery position 031.

[0229] In some other embodiments, the battery position indicated by the solid line is located at battery position 031. If the actual spacing is not equal to the designed spacing, the current position of battery 005 and the target position are spaced apart only in the X-axis direction. Therefore, assembling battery 005 to the target position involves moving battery 005 to the target position in the X-axis direction and assembling the battery. If the actual spacing is equal to the designed spacing, battery 005 is already at the target position. Therefore, assembling battery 005 to the target position involves assembling battery 005.

[0230] The following combination Figure 15 , taking the current position of the battery as the battery position as an example, Figure 11 Step S1033 in the following is described in detail.

[0231] For example, please refer to Figure 15 , Figure 15 Schematic diagram of a battery assembly solution provided in an embodiment of the present application. The battery assembly solution includes the following steps S1033a to S1033d3.

[0232] S1033a, determining the size relationship between the actual spacing and the designed spacing.

[0233] When the actual spacing is greater than the designed spacing, a movement compensation algorithm for the first movement direction is executed. The compensation algorithm for the first movement direction includes steps S1033b1, S1033c1, S1033d1, and S1033e.

[0234] When the actual spacing is smaller than the designed spacing, a second movement direction movement compensation algorithm is executed. The second movement direction compensation algorithm includes steps S1033b2, S1033c2, S1033d2, and S1033e.

[0235] When the actual spacing is equal to the designed spacing, step S103e is executed.

[0236] Step S1033b1: determine that the moving direction is the first moving direction.

[0237] Step S1033c1, determine the target movement amount.

[0238] The execution order of step S1033b1 and step S1033c1 is not critical.

[0239] In some embodiments, the target movement amount is the smaller of the required movement amount and the first movable amount. The required movement amount is the absolute value of the difference between the actual spacing and the designed spacing; the first movable amount is the amount of movement that the battery position can provide to the battery in the first movement orientation. In this embodiment, using the smaller of the required movement amount and the first movable amount as the target movement amount in the compensation algorithm for the first movement orientation can prevent the battery from moving out of the battery position and becoming unfit for assembly.

[0240] Due to the different magnitude relationships between the required moving amount and the first movable amount, step S1033c1 specifically includes the following three situations:

[0241] First case: when the required movement amount is less than the first movable amount, the required movement amount is determined as the target movement amount.

[0242] The second case: when the required movement amount is equal to the first movable amount, the required movement amount (ie, the first movable amount) is determined as the target movement amount.

[0243] The third case: when the required moving amount is greater than the first movable amount, the first movable amount is determined as the target moving amount.

[0244] In some embodiments, as Figure 12As shown, when the battery is in the current position indicated by the solid line, the center line O1 of the battery position 031 and the center line O2 of the battery body 100 are on the same straight line. In this case, the first movable amount is (AB) / 2. Where A is the accommodation dimension of the battery position 031 in the X-axis direction, and B is the dimension of the battery body 100 in the X-axis direction. In the specific implementation process, it can be used Figure 9 The assembly method shown moves the battery 005 to its current position where the center line O1 and the center line O2 are collinear.

[0245] Typically, the design of electronic device 000 meets the following conditions: When the male BTB connector 230 and the female BTB connector 061 are aligned in the X-axis, the X-axis centerline O1 of battery holder 031 and the X-axis centerline O2 of battery body 100 are aligned. This allows battery 005 to be assembled relatively centered in battery holder 031, thereby ensuring a more balanced weight distribution across the X-axis. When centerlines O1 and O2 are aligned, the gap between battery holder 031 and battery body 100 on one side of centerline O1 is (AB) / 2. Based on this, the amount of movement that battery holder 031 can provide for battery 005 in the positive X-axis direction is (AB) / 2, i.e., the first movable amount is (AB) / 2. For example, (AB) / 2 is greater than 0.1 cm.

[0246] In other embodiments, when the battery is in its current position (illustrated by the solid line), the centerline O1 of the battery position 031 may not be collinear with the centerline O2 of the battery body 100. In this case, the first movable distance is the distance ΔP32 between the reference line P2 on one side of the positive X-axis edge of the battery position 031 and the reference line P3 on one side of the positive X-axis edge of the battery body 100. In the figure, since the centerline O1 and the centerline O2 of the battery body 100 are collinear, ΔP32 = (AB) / 2.

[0247] Step S1033d1: Assemble the battery after moving the battery in the first direction by the first movement amount. If the current position of the battery is the battery position, the battery is moved in the first direction by the first movement amount to reach the target position of the battery position.

[0248] Step S1033d1 specifically includes the following three situations corresponding to the three situations in step S1033c1:

[0249] Case 1 (corresponding to the first case): the battery is assembled after being moved in a first direction along a first moving orientation by a first movable amount.

[0250] Case 2 (corresponding to the second case): the battery is assembled after being moved in the first direction along the first moving direction by a required moving amount (ie, a first movable amount).

[0251] Case 3 (corresponding to the third case): the battery is assembled after being moved by a required amount in the first direction along the first moving direction.

[0252] In some other embodiments, when the required movement amount is greater than the first movable amount, the battery may be regarded as defective and discarded (ie, the battery is not assembled).

[0253] Step S1033b2: determine that the moving direction is the second moving direction.

[0254] Step S1033c2, determine the target movement amount.

[0255] The execution order of step S1033b2 and step S1033c2 is not critical.

[0256] In some embodiments, the target movement amount is the smaller of the required movement amount and the second movable amount. The required movement amount is the absolute value of the difference between the actual spacing and the designed spacing; the second movable amount is the amount of movement the battery position can provide for the battery in the second movement orientation. In this embodiment, using the smaller of the required movement amount and the second movable amount as the target movement amount in the compensation algorithm for the second movement orientation can prevent the battery from moving out of the battery position and becoming unfit for assembly.

[0257] Due to the different magnitude relationships between the required moving amount and the second movable amount, step S1033c2 specifically includes the following three situations:

[0258] The first case: when the required moving amount is greater than the second movable amount, the second movable amount is determined as the target moving amount.

[0259] The second case: when the required movement amount is equal to the second movable amount, the required movement amount (ie, the second movable amount) is determined as the target movement amount.

[0260] The third case: when the required movement amount is less than the second movable amount, the required movement amount is determined as the target movement amount.

[0261] In some embodiments, as Figure 13 As shown, when battery 005 is in the current position indicated by the solid line, center line O1 and center line O2 are collinear. In this case, the second movable amount is (AB) / 2. For detailed analysis, please refer to the description of the first movable amount (AB) / 2.

[0262] In other embodiments, when the battery is in its current position (illustrated by the solid line), the centerline O1 of the battery position 031 may not be collinear with the centerline O2 of the battery body 100. In this case, the second movable amount is the distance ΔP41 between the reference line P1 on the negative x-axis edge of the battery position 031 and the reference line P4 on the negative x-axis edge of the battery body 100. In the figure, since the centerline O1 and the centerline O2 of the battery body 100 are collinear, ΔP41 = (AB) / 2.

[0263] Step S1033d2: Assemble the battery after moving the battery in the first direction by the second movement amount toward the target movement. If the current position of the battery is the battery position, the battery is moved in the first direction by the second movement amount toward the target movement amount to reach the target position of the battery position.

[0264] Step S1033d2 specifically includes the following three situations corresponding to the three situations in step S1033c2:

[0265] Case 1 (corresponding to the first case): the battery is assembled after being moved in the first direction along the second moving direction by a second movable amount.

[0266] Case 2 (corresponding to the second case): the battery is assembled after being moved in the first direction along the second moving direction by a required moving amount (ie, a second movable amount).

[0267] Case 3 (corresponding to the third case): the battery 005 is moved in the first direction along the second moving direction by the required movement amount and then assembled.

[0268] In some other embodiments, when the required moving amount is greater than the second movable amount, the battery may be regarded as defective and discarded (ie, the battery is not assembled).

[0269] Step S1033e: alignment assembly. Alignment assembly refers to the assembly steps of moving the battery in the Z-axis direction and fixing the battery, and does not involve moving the battery 005 in the X-axis and Y-axis directions.

[0270] Next, the second solution is explained. Figure 1 and Figure 2 The electronic device 000 shown is provided with a pressure plate. Figure 4 The easily deformable area of ​​the second plate portion 220 is flattened to reduce the risk of the flexible circuit board 200 being arched or pulled.

[0271] For example, please refer to Figure 16 , Figure 16 This is a schematic diagram of the flattened and easily deformed area of ​​the pressure plate provided in an embodiment of the present application.

[0272] The portion of the second plate portion 220 extending to the surface of the main board 006 is the easily deformable area 221, and the BTB connector male socket 230 is disposed in the easily deformable area 221. The pressure plate 007 is attached to the side of the easily deformable area 221 facing away from the main board 006 and is fixed to the easily deformable area 221 by the fixing member 008. In this case, Figure 1 and Figure 2 The electronic device 000 shown also includes Figure 16 The pressure plate 007 and the fixing member 008 are shown.

[0273] In this embodiment, a pressure plate 007 is provided on the side of the easily deformable area 221 facing away from the main board 006, and the pressure plate 007 is fixed to the easily deformable area 221 using a fixing member 008. The force exerted by the fixing member 008 in the thickness direction of the pressure plate 007 (the Z-axis direction in the figure) can be used to make the pressure plate 007 adhere to the surface of the easily deformable area 221, and flatten the easily deformable area 221, thereby solving reliability problems such as white spots on the screen 001 caused by the easily deformable area 221 arching away from the main board 006, or the appearance problem of bulging in the corresponding area of ​​the back cover 002.

[0274] Optionally, the pressing plate 007 may be a steel sheet with a thickness of 0.25 mm. A steel sheet of this thickness has a strong bending resistance and is not easily bent by the flexible circuit board 200, thereby reducing the risk of the flexible circuit board 200 being arched or pulled.

[0275] Accordingly, the present invention also provides a method for assembling a battery 005. Figure 16 Assembly of the battery 005 of the electronic device 000 with the press plate 007 is shown.

[0276] For example, please refer to Figure 17 , Figure 17 A schematic flow chart of another method for assembling a battery 005 provided in an embodiment of the present application, which is applied to a mechanical device for assembling the battery 005; Figure 18 for Figure 17 The structural assembly schematic diagram corresponding to the assembly method shown. Figure 18 The viewing angle of the display is approximately Figure 16 Section view through the cutting line QQ.

[0277] Figure 17 The assembly method of the battery 005 shown includes the following steps S201 to S204:

[0278] In step S201 , the battery is moved to the battery position, and the flexible circuit board of the battery is extended to the board surface side of the main board to be electrically connected to the main board through the flexible circuit board.

[0279] The area of ​​the flexible circuit board 200 extending to the board surface side of the main board 006 is the easily deformable area 221 .

[0280] Combine Figure 16 Before installing the pressure plate 007, move the battery 005 to the battery position 031 (the battery position 031 is not shown in the figure, combined with Figure 2 It can be seen that the battery is located Figure 16 When the battery 005 is moved to the position shown Figure 2 The battery position 031) and the deformable area 221 of the battery 005 is stacked on the board side of the main board 006, which can be referred to Figure 16 As shown in the left picture.

[0281] Step S202: placing a pressing plate on the side of the easily deformable area facing away from the main board.

[0282] like Figure 18 As shown in (a), the pressing plate 007 is placed on the side of the easily deformable area 221 facing away from the main board 006, that is, the pressing plate 007 is placed on the side facing the upper plate surface of the easily deformable area 221, that is, the side of the easily deformable area 221 facing the positive direction of the Z axis.

[0283] In step S203 , the cover plate is used to push the pressing plate toward the side where the easily deformable area is located, so that the easily deformable area is flattened on the surface of the mainboard.

[0284] Among them, a pressure head is provided on the side of the cover plate facing the pressure plate 007. The pressure head contacts the pressure plate 007 before the cover plate. The position where the pressure plate 007 contacts the pressure head is located between the two fixed positions of the pressure plate 007. The fixed positions are used to set the fixing part 008.

[0285] It should be noted that the deformation zone is flattened on the surface of the main board 006 , which means that the easily deformable zone 221 is approximately 180° on the surface of the main board 006 . Figure 18 In the figure, the easily deformable area 221 is flattened on the upper surface of the main board 006 .

[0286] like Figure 18 As shown in (b), using cover plate 009 to push pressing plate 007 toward the side where easily deformable area 221 is located refers to the process of cover plate 009 pressing pressing plate 007 downward, as shown by the arrow in the figure. Because cover plate 009 is pressing pressing plate 007 downward, pressing head 010 first contacts pressing plate 007.

[0287] As a non-limiting example, the Rockwell hardness of the indenter 010 is 50 to 60 HR. For example, the indenter 010 can be made of a soft silicone material with a Rockwell hardness of 50 to 60 HR. In this case, during the downward pressure, the indenter 010 makes soft contact with the pressing plate 007, which is less likely to damage the pressing plate 007. Furthermore, the indenter with a Rockwell hardness of 50 to 60 HR is a soft material that easily deforms during the downward pressure, allowing the cover plate 009 to contact the pressing plate 007, thereby pushing the pressing plate 007 to flatten the easily deformable area 221 on the surface of the main board 006.

[0288] Figure 18 In the embodiment, the fixing position 071 can be a threaded hole, and correspondingly, the fixing member 008 is a fastener such as a bolt that has threads and can be locked with the threaded hole.

[0289] It should be noted that Figure 18 The number of the pressing head 010 shown in the figure is one, and the number of the fixing positions 071 on the pressing plate 007 is two. In other embodiments, there may be more pressing heads 010 and fixing positions 071 on the pressing plate 007, and this embodiment of the present application does not limit this.

[0290] In step S204 , when the cover plate pushes the pressing plate to flatten the easily deformed area, a fixing piece is respectively provided at two fixing positions to fix the pressing plate to the main board.

[0291] like Figure 18 As shown in (c), in order to achieve the fixing member 008 to fix the pressure plate 007 to the main board 006, the main board 006 has a threaded hole opposite to the threaded hole on the pressure plate 007, so that bolts and other fasteners can pass through the threaded hole on the pressure plate 007 and extend into the threaded hole on the main board 006 for locking, thereby achieving the fixing of the pressure plate 007 to the main board 006. After the bolts and other fasteners are locked, Figure 18 The state shown in (d).

[0292] In the related art, cover plate 009 is not provided with a pressing head 010. When two fixing members 008 are used to secure pressure plate 007, the easily deformable area 221 between the two fixing positions 071 is prone to arching away from the mainboard 006, causing reliability issues such as white spots on the screen or cosmetic issues such as bulging in the corresponding area of ​​the back cover. In this embodiment, pressing head 010 contacts and presses down pressure plate 007 before cover plate 009. Based on this, when two fixing members 008 are used to secure easily deformable area 221, the area between the two fixing positions 071 is supported by pressing head 010 and is less likely to arch, thus resolving reliability issues such as white spots on the screen or cosmetic issues such as bulging caused by easily deformable area 221 arching away from the mainboard 006.

[0293] It is also understandable that Figure 11 、 Figure 15 as well as Figure 17 The provided embodiments may be implemented in combination or individually, and the embodiments of the present application do not specifically limit this.

[0294] The above is only a specific implementation method of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with this technical field can easily think of changes or replacements within the technical scope disclosed in this application, which should be covered by the protection scope of the present application.
