Description

Technical Field

[0001] This application relates to the field of electronic technology, and in particular to a flexible circuit board, a battery, an electronic device, and a method for assembling the battery. Background Technology

[0002] With the increasing demand for thinner and lighter electronic devices such as tablets and mobile phones, controlling the thickness of these devices has become a key research and development focus in the industry. Excessive thickness will prevent these devices from meeting the requirements for thinness and lightness.

[0003] The flexible circuit board of the battery is cut from a substrate and is used to electrically connect to the motherboard, serving to transmit electrical energy and battery status signals. Since the thickness of the flexible circuit board occupies space within the electronic device's overall thickness, reducing the thickness of the flexible circuit board can reduce the overall thickness of the electronic device, allowing it to meet the requirements for a thinner and lighter design.

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

[0005] This application provides a flexible circuit board, a battery, an electronic device, and a method for assembling the battery. The flexible circuit board balances thickness and substrate utilization, increasing substrate utilization while reducing thickness.

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

[0007] In a first aspect, embodiments of this application provide 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 disposed opposite to each other in a first direction, the first direction being 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 fixes 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 a second direction. The second direction is perpendicular to both 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 technologies, the second plate portion of a flexible circuit board is bent 180° in the first direction to the side of the first plate portion (i.e., one side in the thickness direction of the first plate portion) and stacked to form a double-layer structure, thereby increasing the thickness of the flexible circuit board. Before bending the second plate portion, the first and second plate portions of the flexible circuit board are arranged in the first direction. 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 and first plate portions are also arranged in the first direction, when cutting the flexible circuit board from the substrate, a larger substrate size is cut in the first direction and a smaller substrate size is cut in the second direction, resulting in low substrate utilization.

[0009] In this flexible circuit board, the second and first plates are not stacked in the thickness direction of the first plate, resulting in a single-layer structure with a lower thickness compared to related technologies. Simultaneously, the first end of the second plate fixes the second end of the first plate, and the second end extends from the first end to one side of the first plate in a second direction. Therefore, in this embodiment, the second plate does not continue to extend along the first direction and be arranged with the first plate in that direction; instead, it extends to one side of the first plate in a second direction perpendicular to the first direction. This facilitates a balance between the dimensions of the substrate cut in the first and second directions, thereby improving the utilization rate of the substrate. Thus, the flexible circuit board provided by this embodiment reduces thickness while improving the utilization rate of the substrate.

[0010] As a non-limiting embodiment, the first plate portion is constructed in the shape of an elongated strip. The first direction is the length direction of the first plate portion, and the second direction is the width direction of the first plate portion.

[0011] In this embodiment, when the first plate is elongated and the first direction is the length direction of the first plate, the low utilization rate of the substrate is more pronounced in the related technology. Therefore, the design that extends the second end of the second plate to one side of the first plate in the second direction can further improve the utilization rate of the substrate, and the improvement effect on the low utilization rate of the substrate is more significant.

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

[0013] This embodiment provides a specific implementation where the second end of the second plate extends to one side of the first plate in a second direction. The second end of the second plate first 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 extends again in the second orientation of the first direction, roughly forming a U-shape with uneven heights. Because the second orientation is opposite to the first orientation, the second end of the second plate is essentially extending back in the opposite direction after extending in the first orientation. With a third distance greater than the first distance, plus the second distance extended in the second direction, it can extend to one side of the first plate in the second direction. Based on the foregoing analysis, extending the second end of the second plate to one side of the first plate in the second direction helps to balance the substrate dimensions cut in the first and second directions, thereby improving the utilization rate of the substrate.

[0014] Secondly, embodiments of this application provide a battery. The battery includes a battery body and a flexible circuit board as provided in any of the first aspects. The thickness direction of a first portion of the flexible circuit board is the same as the thickness direction of the battery body, and a first end of the first portion is electrically connected to the battery body. A second portion of the flexible circuit board extends to one side of the battery body.

[0015] It is understood that, unless otherwise stated, the beneficial effects of the battery provided by the embodiments of the second aspect described above can be found in the relevant description of the flexible circuit board in the first aspect described above, and will not be repeated here.

[0016] As can be seen from the foregoing analysis of the flexible circuit board, the second and first plates are not stacked in the thickness direction of the first plate, resulting in a single-layer flexible circuit board structure. When the thickness direction of the first plate of the flexible circuit board is the same as the thickness direction of the battery body (i.e., the battery's thickness direction), the thickness of the single-layer flexible circuit board is distributed along the battery's thickness direction. Compared to the related art's double-layer flexible circuit board where the thickness is distributed along the battery's thickness direction, the single-layer flexible circuit board structure is advantageous in reducing the battery's thickness at the flexible circuit board location.

[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 can be electrically connected to the main board provided on one side of the battery body through the first electrical connection portion provided at the second end of the second plate portion.

[0018] Thirdly, embodiments of this application provide an electronic device. The electronic device includes a motherboard and a battery as described in any of the second aspects. A second electrical connection portion is provided on the surface of the motherboard. The motherboard is disposed on one side of the battery body, and a second end of a second plate portion of the battery's flexible circuit board extends to the surface of the motherboard; the second plate portion is electrically connected to the second electrical connection portion via a first electrical connection portion on the second plate portion.

[0019] It is understood that, unless otherwise stated, the beneficial effects of the electronic device provided by the embodiments of the third aspect described above can be found in the relevant description of the battery in the second aspect described above, and will not be repeated here. In electronic devices with requirements for thinness and lightness, 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, and help meet the requirements for thinness and lightness of the electronic device.

[0020] The second end of the second plate 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 plate portion and the second electrical connection portion of 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 also includes a pressure plate. The portion of the second plate extending to the side of the motherboard is a deformable area. A first electrical connection portion is disposed in the deformable area. The pressure plate is attached to the side of the deformable area facing away from the motherboard. The pressure plate is fixed to the motherboard by a fastener.

[0022] It is understandable that when the deformable area arches away from the motherboard, if the side of the deformable area facing away from the motherboard is the screen, it is easy to cause the screen to top up, resulting in reliability issues such as white spots on the screen; if the side of the deformable area facing away from the motherboard is the back cover, it is easy to cause the back cover to top up, resulting in the appearance of bulging in the corresponding area of ​​the back cover.

[0023] Based on this, in this embodiment, by attaching a pressure plate to the side of the deformable area facing away from the motherboard and fixing the pressure plate to the motherboard using fasteners, a force can be applied towards the deformable area in the thickness direction of the pressure plate. This force causes the pressure plate to adhere to the surface of the deformable area, flattening the deformable area and thus solving reliability or appearance problems such as white spots on the screen caused by the deformable area arching away from the motherboard.

[0024] Fourthly, embodiments of this application provide a battery assembly method for assembling a battery in an electronic device. The electronic device has a battery compartment and a motherboard located on one side of the battery compartment. The assembly method includes: with the motherboard assembled to one side of the battery compartment and the battery in its current position, obtaining a first position of the flexible circuit board of the battery and a second position of the motherboard; the first position characterizing the position of a first electrical connection portion of the flexible circuit board; the second position characterizing the position of a second electrical connection portion of the motherboard; assembling the battery to a target position of the battery compartment according to the first and second positions, the target position being a position where the first and second electrical connections correspond; and electrically connecting the first and second electrical connections.

[0025] In the relevant assembly methods, a center alignment algorithm is used for battery assembly, that is, assembly is performed by aligning the center line of the battery body with the center line of the battery position. This assembly method uses the positions on the battery body and the battery position as reference positions during battery assembly, which causes the accumulation of tolerances such as incoming material tolerances and assembly tolerances, resulting in misalignment between the first electrical connection on the flexible circuit board and the second electrical connection on the main board.

[0026] It should be noted that if the first electrical connection of the battery and the second electrical connection of the motherboard are misaligned, forcibly connecting the first electrical connection of the battery and the second electrical connection of the motherboard will result in the following two situations for the flexible circuit board: First, redundancy will cause bulging, resulting in reliability issues such as white spots on the screen or bulging appearance issues in the corresponding area of ​​the back cover; Second, pulling will cause tearing or weak electrical connection, thereby reducing the reliability of the electrical connection between the battery and the motherboard.

[0027] In this embodiment, during battery assembly, the first position of the flexible circuit board of the battery is used to characterize the position of the first electrical connection, and the second position of the main board is used to characterize the position of the second electrical connection, using these as reference positions for assembly. Since the first position is the location of the first electrical connection on the flexible circuit board, and the second position is the location of the second electrical connection on the main board, compared to methods that characterize the position of the first electrical connection using other structures outside the flexible circuit board (such as the center line of the battery body in related assembly methods), and the position of the second electrical connection using other structures outside the main board (such as the center line of the battery position in related assembly methods), this breaks the dimensional chain and avoids introducing material tolerances for the battery position, the battery body, the assembly tolerances between the battery position and the battery body, and the assembly tolerances between the battery body and the flexible circuit board. This allows for a more accurate characterization 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 flexible circuit board of the battery and the second position of the main board as reference positions during battery assembly can reduce the impact of the aforementioned tolerances (such as the incoming material tolerance of the battery position, the incoming material tolerance of the battery body, the assembly tolerance between the battery position and the battery body, and the assembly tolerance between the battery body and the flexible circuit board) on the misalignment between the first electrical connection and the second electrical connection. This can improve the misalignment of the first electrical connection on the flexible circuit board and the second electrical connection on the main board, ensuring that the first and second electrical connections correspond. With the first and second electrical connections corresponding, electrically connecting them can improve the arching or stretching phenomenon of the flexible circuit board. This can solve reliability problems such as white spots on the screen caused by the arching of the flexible circuit board, or appearance problems such as arching in the corresponding area of ​​the back cover. It can also solve problems of tearing or poor contact caused by stretching of the flexible circuit board, thereby improving the reliability of the electrical connection between the battery and the main board.

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

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

[0031] For the battery in the electronic device according to any one of the third aspects, since the flexible circuit board used is a single-layer flexible circuit board as described in any one of the first aspects, it is impossible to adjust the position of the first electrical connection in the first direction by adjusting the position of the second board relative to the first board in the first direction. Therefore, the assembly of the battery in the electronic device according to any one of the third aspects is suitable for using this assembly method to improve the misalignment of the first electrical connection and the second electrical connection 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-described assembly of the battery to the target position of the battery position based on 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] Based on the actual spacing and the designed spacing, the battery is assembled to the target position. If the actual spacing is not equal to the designed spacing, and the battery is assembled from the current position to the target position, the target movement is performed along the moving direction in the first direction by a specified amount. The moving direction is determined based on the 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, and the battery is assembled from the current position to the target position, no movement is performed 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 and the designed spacing are the same can characterize whether the first electrical connection part and the second electrical connection part are misaligned in the first direction.

[0036] The actual spacing is not equal to the designed spacing, indicating that the first and second electrical connections are misaligned in the first direction. The relationship between the actual spacing and the designed spacing characterizes the direction of misalignment in the first and second electrical connections in the first direction. Moving the battery in the opposite direction of the misalignment (i.e., the moving direction) can mitigate the misalignment in the first and second electrical connections in the first direction, promoting correspondence between them. The absolute value of the difference between the actual spacing and the designed spacing characterizes the amount of misalignment in the first and second electrical connections in the first direction. This misalignment amount is equal to the required movement of the battery in the first direction if the first and second electrical connections were not misaligned. Therefore, in this embodiment, the target movement amount is determined based on the absolute value of the difference between the actual spacing and the designed spacing, which is equivalent to determining it based on the required movement amount, helping to ensure correspondence between the first and second electrical connections in the first direction. Based on this, when the battery is assembled from its current position to the target position of the battery location, moving the target movement amount in the first direction along the aforementioned moving direction helps to assemble the battery to the target position where the first and second electrical connections correspond in the first direction.

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

[0038] It is understandable that when the first electrical connection and the second electrical connection are corresponding in the first direction, connecting the first electrical connection and the second electrical connection will not easily result in the aforementioned pulling or arching phenomenon.

[0039] As a non-limiting embodiment, 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 a first direction towards a first misalignment direction. That is, the misalignment direction of the first and second electrical connection portions in the first direction is the first misalignment direction, which is one of the first and second directions in the first direction. It is necessary to move the first electrical connection portion towards a first moving direction opposite to the first misalignment direction, that is, the moving direction is the first moving direction, which is another of the first and second directions in the first direction.

[0040] The target movement amount is the smaller of the first movable amount and the required movement amount. The first movable amount is the movement that the battery position can provide to the battery in the first movement direction. The required movement amount is the absolute value of the difference between the actual spacing and the designed spacing. The target movement amount, which is the smaller of the first movable amount and the required movement amount, 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 up to the first movable amount, 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, which is also the absolute value of the difference between the actual distance and the design distance.

[0043] Third, when the required movement amount equals 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, which is also the absolute value of the difference between the actual distance and the design distance.

[0044] In this embodiment, the target movement amount is the smaller of the required movement amount and the first movable amount, which can prevent the battery from being moved out of the battery position and thus making assembly impossible.

[0045] When the actual spacing is less than the design spacing, the first electrical connection is offset in the first direction towards a first misalignment direction. That is, the misalignment direction of the first electrical connection and the second electrical connection in the first direction is a second misalignment direction, which is the other of the first and second directions in the first direction. The first electrical connection needs to be moved in the opposite direction to the second misalignment direction, i.e., the movement direction is the second movement direction, which is one of the first and second directions in the first direction. The target movement amount is the smaller of the second movable amount and the required movement amount. 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 being the smaller of the second movable amount and the required movement amount can be adapted to the explanation of the three cases where the momentum is the smaller of the first movable amount and the required movement amount.

[0046] As a non-limiting embodiment, when the centerline of the battery compartment 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. Wherein, A is the accommodating dimension of the battery compartment 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: with the first and second electrical connections aligned in the first direction, the centerline of the battery compartment and the centerline of the battery body in the first direction are collinear. This allows the battery to be assembled in a relatively centered position, resulting in a more balanced weight distribution of the electronic device in the first direction. When the centerlines of the battery compartment and the battery body in the first direction are collinear, the single-sided gap between the battery compartment and the battery body is (AB) / 2. Based on this, the amount of movement that the battery compartment can provide to the battery body in the first and second directions in the first direction is (AB) / 2, i.e., the first movable amount and the second movable amount are (AB) / 2. For example, (AB) / 2 is greater than 0.1 cm.

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

[0049] It should be noted that the first end of the second plate is called the fixed end because it fixes the second end of the first plate, and the second end of the second plate is a free end before the first electrical connection part is electrically connected to the second electrical connection part. Because the second plate is a flexible structure, the position of the second plate closer to the free end in the first direction is more prone to change and less suitable for use as the first position.

[0050] Because the second end of the second plate extends to one side of the first plate in the second direction, the first plate can characterize the position of the second end (i.e., the free end) of the second plate in the first direction. Based on this, this embodiment selects the first position as the edge of the second plate facing away from the first plate in the first direction, which is equivalent to selecting the position of the second plate furthest from the free end in the first direction as the first position. This position is less prone to change compared to other positions of the second plate, and has less impact on the misalignment of the first and second electrical connections in the first direction. Furthermore, selecting the edge of the second plate facing away from the first plate in the first direction as the first position helps to obtain the actual distance between the first and second positions in the first direction during battery assembly, thereby helping to ensure that the first and second electrical connections correspond in the first direction.

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

[0052] It should be noted that because the exposed copper area on the motherboard has a significant color difference compared to other parts of the motherboard (the motherboard is usually green), it is easily distinguishable during image recognition. Therefore, in this embodiment, the edge of the exposed copper area on the motherboard is used as the second location, which is easily identified during image recognition, thus facilitating the rapid and accurate capture of the second location. Furthermore, selecting one edge of the exposed copper area in the first direction helps to obtain the actual distance between the first and second locations in the first direction during battery assembly, thereby helping to ensure that the first electrical connection and the second electrical connection correspond in the first direction.

[0053] Fifthly, embodiments of this application also provide another battery assembly method for assembling a battery in the electronic device provided in the third aspect, the electronic device having a battery compartment. The assembly method includes: moving the battery to the battery compartment of the electronic device, and extending the flexible circuit board of the battery to the side of the motherboard to electrically connect it to the motherboard via the flexible circuit board, the area where the flexible circuit board extends to the side of the motherboard being a deformable area; placing a pressure plate on the side of the deformable area facing away from the motherboard; using a cover plate to push the pressure plate towards the side where the deformable area is located, so that the deformable area is flattened on the surface of the motherboard; 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, the position of the pressure head contacting the pressure plate is located between two fixed positions, the fixed positions being used to provide fixing members; when the cover plate pushes the pressure plate to flatten the deformable area, a fixing member is provided at each of the two fixed positions to fix the pressure plate to the motherboard.

[0054] In related technologies, the cover plate does not have a pressure head. When two fasteners are used to fix the easily deformable area, the easily deformable area is prone to arching away from the motherboard between the two fasteners, which can cause 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 pressure head contacts and presses down on the pressure plate before the cover plate. Based on this, when using two fasteners to fix the easily deformable area, the easily deformable area is held in place by the pressure head between the two fasteners and is less likely to arch up, thus solving reliability or appearance problems such as white spots on the screen caused by the easily deformable area arching away from the motherboard.

[0056] As a non-limiting embodiment, the indenter has a Rockwell hardness of 50 to 60 HR. In this case, the indenter is less likely to damage the pressure plate during soft contact and pressing. Furthermore, the indenter with a Rockwell hardness of 50 to 60 HR is a soft material that easily deforms during pressing to allow the cover plate to contact the pressure plate, thereby pushing the pressure plate to flatten the deformable area on the main plate surface.

Exemplarily, the electronic device may be a mobile phone, tablet computer, desktop computer, laptop computer, handheld computer, notebook computer, ultra-mobile personal computer (UMPC), netbook, cellular phone, personal digital assistant (PDA), augmented reality (AR) / virtual reality (VR) device, or any device including a battery. This application does not impose any special limitations on the specific form of the electronic device. The following description uses a tablet computer as an example.

[0083] For example, please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of an electronic device 000 provided in an embodiment of this application. Figure 2 for Figure 1 The diagram shows an exploded view of the structure of electronic device 000.

[0084] In this embodiment, the electronic device 000 is a tablet computer, including a screen 001, a back cover 002, and Figure 2 The components on display are the mid-plate 003, camera module 004, battery 005, and motherboard 006. This is understandable. Figure 1 and Figure 2 The electronic device 000 is shown only schematically, and the actual shape, size, location, and construction of these components are not subject to change. Figure 1 and Figure 2 The limitations. Furthermore, in other embodiments of this application, the electronic device 000 may include more or fewer components than illustrated, or combine some components, or split some components, or have different component arrangements.

[0085] These components will be described in detail below.

[0086] Screen 001 is used to display images, videos, etc. Screen 001 can be a flexible or 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 (MLED) display screen, a micro organic light-emitting diode (MLED) display screen, a quantum dot light-emitting diode (QLED) display screen, or a liquid crystal display (LCD).

[0087] For ease of description below, an XYZ coordinate system is established. The length direction of electronic device 000 is defined as the X-axis, the width direction as the Y-axis, and the thickness direction as the Z-axis. It should be noted that the coordinate system settings for electronic device 000 can be flexibly configured according to actual needs.

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

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

[0090] A bezel 022 surrounds the sides of the screen 001 and the back panel 021, and is fixedly connected to the screen 001 and the back panel 021 respectively. Exemplarily, the bezel 022 can be fixedly connected to the screen 001 by adhesive. Exemplarily, the bezel 022 and the back panel 021 are integrally formed; in some other embodiments, the bezel 022 can also be integrally formed with the middle plate 003.

[0091] It can be understood that the screen 001, back panel 021, and frame 022 together enclose the receiving space of the electronic device 000, so as to place the functional components of the electronic device 000 through this receiving space, such as... Figure 2 The camera module 004, battery 005, motherboard 006 and other functional components shown also provide a sealing and protection function for the functional components located in the housing space.

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

[0093] The camera module 004 is used to capture photos / videos. There can be one or more camera modules 004; only one front-facing camera is shown in the figure. The camera module 004 is fixed to the side of the middle plate 003 facing the screen 001, specifically near the center of the long side of the middle plate 003 (the center of the edge extending along the X-axis). "Near the center" means that the distance between this location and the center of the long side of the middle plate 003 is small, and this distance can be set as needed. Of course, in some other embodiments, the camera module 004 can be fixed to other positions on the middle plate 003. For example, the camera module 004 can be fixed to the side of the middle plate 003 facing the back plate 021; or, for example, the camera module 004 can be fixed to one of the four corners of the middle plate 003. Exemplarily, the camera module 004 can be fixed and supported on the middle plate 003 by means of threaded connection, snap-fit, welding, etc., and the light-incident surface of the camera module 004 faces the screen 001. A light-transmitting area 011 is provided on 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] Battery 005 is used to power the functional components of electronic device 000 that require power. Figure 2 In the diagram, a battery slot 031 is provided on the middle plate 003 to accommodate the battery 005. The battery slot 031 can be a hole on the middle plate 003, spaced apart on one side of the camera module 004 in the negative Y-axis direction, to facilitate the installation of the motherboard 006 between the battery 005 and the camera module 004. The battery 005 is installed in the battery slot 031 and is stacked on top of the screen 001 and the back plate 021 in the Z-axis direction. To illustrate the battery slot 031, the diagram is disassembled along the Z-axis direction, showing the battery 005 and the middle plate 003.

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

[0096] The motherboard 006 is an important carrier for functional components, used for electrical connections between pairs of functional components, some integrated and some not. For example, the motherboard 006 can be electrically connected to both the power management module (not shown in the figure) integrated on the motherboard 006 and the battery 005 not integrated on the motherboard 006, thus electrically connecting the power management module and the battery 005. In this way, the battery 005 can transmit power to the power management module via the motherboard 006, thereby supplying power to the functional components of the electronic device 000 that require power.

[0097] Figure 2 In this diagram, a motherboard slot 032 is provided on the middle plate 003 to accommodate the motherboard 006. The motherboard slot 032 can be a hole on the middle plate 003, located on one side of the battery 005 along the Y-axis, specifically on the positive Y-axis side. Since the middle plate 003 and motherboard 006 are not disassembled along the Z-axis in the diagram, the position of the motherboard slot 032 can be roughly referenced to the position of the motherboard 006. The motherboard slot 032 on the middle plate 003, where the motherboard 006 is located, is generally (except for a few exceptions) on the side of the battery 005 along the Y-axis closer to the camera module 004, and is stacked with the screen 001 and the back plate 021 along the Z-axis. Of course, in some other embodiments, the motherboard 006 can also be fixed to other positions on the middle plate 003, for example, the motherboard 006 may be generally located on one side of the battery 005 along the X-axis.

[0098] It should be noted that, with the increasing demand for thinner and lighter electronic devices, controlling the thickness of electronic devices has become a key research and development focus in the industry. Excessive thickness of electronic devices would prevent them from meeting the requirements for thinness and lightness. Figure 2 In this context, the thickness space occupied by different parts of the battery 005 in the electronic device 000 varies, specifically determined by the dimensions of each part in the Z-axis direction. To meet the requirements for a thinner and lighter electronic device 000, it is necessary to control the dimensions of each part of the battery 005 in the Z-axis direction.

[0099] In related technologies, the flexible circuit board of battery 005 has a large dimension in the Z-axis direction, resulting in a thicker battery 005 at the flexible circuit board, which prevents the electronic device 000 from meeting the requirements for thinness and lightness. Based on this, the embodiments provided in this application... Figure 2 The battery 005 in the device reduces its thickness at the flexible circuit board by reducing the thickness of the flexible circuit board it contains, thereby reducing the thickness of the electronic device 000 to meet the requirement of a thinner and lighter electronic device 000. The following section combines... Figure 3 The battery 005 provided in the embodiments of this application will be described.

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

[0101] Battery body 100 can be understood as battery 005 placed in Figure 2 The battery portion (excluding the flexible circuit board 200) shown is at battery position 031. The battery body 100 includes, but is not limited to, the cell assembly 110. For example, Figure 3 In the battery body 100, there may also be a protection circuit board 120, etc.

[0102] The cell assembly 110 is the core component of the battery 005, responsible for storing and releasing electrical energy. It typically consists of a positive electrode, a negative electrode, an electrolyte, and a separator, and generates current through a chemical reaction. To increase the capacity of the battery 005, in some embodiments, the cell assembly 110 can be formed by combining multiple cells 111. For example, Figure 3 In this embodiment, the battery cell assembly 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, and this application embodiment does not limit this.

[0103] The battery cell assembly 110 has a roughly plate-like structure in appearance. A plate-like structure refers to a structure whose length and width are much greater than its thickness. For a plate-like structure, the surfaces with length and width are called the plate surfaces, and the thickness direction is perpendicular to the plate surfaces. In the illustration, the length direction of the battery cell assembly 110 is the X-axis direction, the width direction is the Y-axis direction, and the thickness direction is the Z-axis direction. In this embodiment, the two sides of the battery cell assembly 110 facing away from each other in the X-axis direction are referred to as the left and right sides, the two sides facing away from each other in the Y-axis direction are referred to as the upper and lower sides, and the two plate surfaces facing away from each other in the Z-axis direction are referred to as the upper and lower plate surfaces. Similar terms such as "plate" used in this embodiment can be understood with reference to the explanations herein. It should be noted that the thickness direction of battery 005 is determined by the thickness direction of battery body 100. In this embodiment, the thickness direction of battery body 100 is the Z-axis direction. Therefore, the thickness direction of battery 005 is also the Z-axis direction.

[0104] The protection circuit board 120 is an important component of battery 005 and is electrically connected to the cell assembly 110. It monitors the voltage and charging / discharging current of the cell assembly 110 via electronic circuitry and controls the current loop in abnormal situations to protect the cell assembly 110 from damage. Its main functions include overcharge protection, over-discharge protection, overcurrent protection, short-circuit protection, and temperature protection to prevent battery 005 from being damaged or experiencing safety accidents due to 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 for monitoring the battery 005's status and controlling protection actions.

[0105] Figure 3 In this embodiment, the protective circuit board 120 covers the lower surface (the side facing away from the upper surface of the battery cell assembly 110), the left side, and the right side of the battery cell assembly 110. Furthermore, the protective circuit board 120 extends to the side facing the upper surface of the battery cell assembly 110, that is, to the side of the battery cell assembly 110 in the positive Y-axis direction. In this embodiment, the portion of the protective circuit board 120 extending to the side of the battery cell assembly 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] Flexible circuit board 200 refers to a circuit board with bendable characteristics, used for electrical connection of battery 005. Figure 2 The component of the motherboard 006. Specifically, the flexible circuit board 200 extends from one side of the extension 121 in the positive Z-axis direction to the other side of the extension 121 in the positive Y-axis direction, so as to facilitate connection with... Figure 2 The motherboard 006, located on one side of the battery position 031 in the positive Y-axis direction, is electrically connected, thereby realizing the electrical connection between the battery 005 and the motherboard 006.

[0107] When the battery 005 is electrically connected to the motherboard 006, on the one hand, the battery 005 can release the electrical energy stored in the cell group 110 to the motherboard 006 through the flexible circuit board 200, and the motherboard 006 can also store electrical energy in the 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 motherboard 006 through the flexible circuit board 200, and the motherboard 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 this context, since the thickness direction of the flexible circuit board 200 is in the Z-axis direction, the thickness of the flexible circuit board 200 is its dimension 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 space occupied by the battery 005 at the flexible circuit board 200 on the thickness of the electronic device 000, and meeting the requirement for a thinner and lighter electronic device 000.

[0109] In related technologies, the flexible circuit board 200 has a double-layer structure, resulting in a large thickness of the flexible circuit board 200. This increases the thickness of the battery 005 at the flexible circuit board 200, thus preventing the electronic device 000 from meeting the requirements for thinness and lightness. Based on this, the embodiments provided in this application... Figure 3 The flexible circuit board 200 in the middle 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 and meeting the requirements of the electronic device 000 for thinner and lighter designs. The following is in conjunction with... Figures 4 to 5 Conduct a 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 this application. The flexible circuit board 200 can be applied to... Figure 3 The battery 005 shown is an example of a battery with a flexible circuit board 200. This battery 005 can be used in upright structures (the battery is mounted on the side of the middle plate facing the back cover), flip-chip structures (the battery is mounted on the side of the middle plate facing the screen), high-power batteries (increasing battery power by increasing or decreasing the dimensions of the battery in the X-axis and Y-axis directions without increasing thickness), and electronic devices 000 where thinness is required.

[0111] The flexible circuit board 200 is used to electrically connect a first device and a second device, thereby enabling signal transmission between the first device and the second device. The flexible circuit board 200 is applied to... Figure 3 In the case of battery 005 shown, the first device can be Figure 3 The battery body 100 in the middle, the second device can be Figure 2 The motherboard 006 in the example. Of course, in other embodiments, the flexible circuit board 200 can also be used in other scenarios to achieve electrical connections between the first and second devices in those other scenarios. The following describes the application of the flexible circuit board 200 in... Figure 3 The following explanation uses battery 005 as an example.

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

[0113] Flexible circuit board 200 refers to a circuit board with bendable characteristics. It should be noted that having bendable characteristics does not require the flexible circuit board 200 to be a flexible structure throughout. In specific implementation, at least a portion of the flexible circuit board 200 is a flexible structure, which is sufficient to give the flexible circuit board 200 bendable characteristics.

[0114] for example, Figure 4 In this design, the first plate portion 210 is a rigid structure, and the second plate portion 220 is a flexible structure, thereby giving the flexible circuit board 200 bendable characteristics. In this case, the flexible circuit board 200 can be cut from a panel formed by splicing rigid and flexible substrates. Of course, in some other embodiments, all flexible circuit boards 200 are flexible structures; this application does not limit this aspect.

[0115] The first plate portion 210 and the second plate portion 220 will be described below.

[0116] First, let's explain the first plate section 210.

[0117] The first plate portion 210 includes a first end 210a and a second end 210b disposed opposite to each other in a first direction (as shown in the figure, the X-axis direction). The first direction in the figure is the X-axis direction, perpendicular to the thickness direction of the first plate portion 210 (the Z-axis direction in the figure). Unless otherwise specified, subsequent embodiments will use the X-axis direction to represent the first direction and the Z-axis direction to represent the thickness direction of the first plate portion 210. The first plate portion 210 is a structure of a flexible circuit board 200 for electrically connecting a first device, the first device being... Figure 3 The battery body 100 in the middle.

[0118] Next, the second plate section 220 will be explained.

[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, which results in the thickness direction of the second plate portion 220 not necessarily being in the Z-axis direction, but rather approximately in the Z-axis direction.

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

[0121] The first end 220a of the second plate 220 fixes the second end 210b of the first plate 210 (specifically, the end face of the second end 210b of the first plate 210 in the X-axis direction can be fixed).

[0122] The second end 220b of the second plate portion 220 is provided with a first electrical connection portion (as shown in the figure, BTB connector male socket 230), for connecting... Figure 2 The motherboard 006 in the middle. Figure 4The BTB connector male socket 230 is shown from the rear view of the second end 220b of the second board portion 220. Accordingly, please refer to the reference. Figure 2 The motherboard 006 has a second electrical connection part (such as BTB connector female 061) that is electrically connected to the first electrical connection part.

[0123] The second end 220b of the second plate portion 220 extends from the first end 220a of the second plate portion 220 to one side of the first plate portion 210 in a second direction, the second direction being perpendicular to the first direction and the thickness direction of the first plate portion 210. Figure 4 In the illustration, when the first direction is the X-axis and the thickness direction of the first plate portion 210 is the Z-axis, the second direction is the Y-axis. Unless otherwise specified, the following embodiments will be described using the Y-axis 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 that side of the first plate portion 210 in the Y-axis direction (the area between the dashed lines W1 and W2 in the illustration), that is, the area corresponding to the projection path of the orthographic projection of that side along the Y-axis direction. Figure 4 In the middle, the second end 220b of the second plate portion 220 specifically extends to one side of the first plate portion 210 in the positive Y-axis direction.

[0124] In the Z-axis direction, the second plate portion 220 and the first plate portion 210 do not overlap. That is, 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, and the resulting flexible circuit board 200 has a single-layer structure in the Z-axis direction. However, in related technologies, the flexible circuit board 200 has a double-layer structure in the Z-axis direction.

[0125] Please refer to the reference. Figure 5 , Figure 5 A schematic diagram of the structure of a flexible circuit board 200 provided for related technologies. 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 facing away from each other in the X-axis direction.

[0126] Because the second plate portion 220 is a flexible structure with bendable characteristics, the second plate portion 220 can be bent 180° in the X-axis direction to the plate surface side of the first plate portion 210 (i.e., one side of the first plate portion 210 in the Z-axis direction) for stacking (the state after bending is shown by solid lines 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, its second end 220b extends away from the first plate portion 210 in the X-axis direction. The first plate portion 210 and the second plate portion 220 are arranged sequentially in the X-axis direction, and the flexible circuit board 200 occupies a 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 the flexible circuit board 200 having a double-layer structure, which makes the flexible circuit board 200 thicker.

[0128] It can be seen that, compared to Figure 5 Regarding the double-layer flexible circuit board 200 shown, Figure 4 The thickness of the single-layer flexible circuit board 200 shown is reduced. This results in a thickness gain of 0.25 mm for the flexible circuit board 200.

[0129] In Figure 4 The single-layer flexible circuit board 200 shown is applied to Figure 3 The battery 005 shown is assembled into Figure 2 When referring to the electronic device 000 shown, please refer to the relevant documentation. Figure 6 , Figure 6 for Figure 2 A plan view of the middle board 003 and some of the functional components mounted on it in the electronic device 000 shown. Figure 6 In the middle, some functional components installed on the middle board 003 include camera module 004, battery 005, and motherboard 006, etc.

[0130] For electrical connection to the battery body 100, a first plate portion 210 extends to one side of the cell assembly 110 in the positive Y-axis direction, and is arranged in the Z-axis direction with an extension portion 121 also located on the same side of the cell assembly 110 in the positive Y-axis direction, and the first plate portion 210 and the extension portion 121 are face-to-face with each other. The face-to-face surfaces of the first plate portion 210 and the extension portion 121 are electrically connected, thereby realizing the electrical connection of the flexible circuit board 200 to the battery body 100. Exemplarily, the method of electrical connection between the flexible circuit board 200 and the extension portion 121 includes, but is not limited to, soldering and plugging.

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

[0132] In order to electrically connect the motherboard 006, the second end 220b of the second board portion 220 extends to one side of the battery body 100 in the positive Y-axis direction, opposite the board surface of the motherboard 006 which is also on the same side of the battery body 100 in the positive Y-axis direction. The second end 220b of the second board portion 220 is fastened to the BTB connector female seat 061 on the board surface side of the motherboard 006 through the BTB connector male seat 230 provided thereon to achieve electrical connection, thereby realizing the electrical connection of the flexible circuit board 200 to the motherboard 006.

[0133] Figure 6 In this configuration, the thickness direction of both the first plate portion 210 and the battery body 100 (determined by the thickness direction of the cell assembly 110) is along the Z-axis. 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 also decreases. Reducing the thickness of the battery 005 at the flexible circuit board 200 can decrease the impact of the battery 005 on the thickness of the flexible circuit board 200. Figure 2 The thickness space occupied by the illustrated electronic device 000 is reduced, thereby meeting the requirement for a thinner and lighter electronic device 000. Furthermore, 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 impact on the thickness space is reduced. Figure 2 The space occupied by the electronic device 000 shown in the X-axis direction.

[0134] In addition, compared to Figure 5 Regarding 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 the following: Figure 7 , Figure 7 for Figure 4 The flexible circuit board 200 shown and Figure 5 The diagram shows the corresponding cutting positions of the flexible circuit board 200 on the panel.

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

[0137] because Figure 5 The first plate portion 210 and the second plate portion 220 of the flexible circuit board 200 shown are arranged sequentially in the X-axis direction, and the flexible circuit board 200 occupies a large space in the X-axis direction. Based on this, Figure 7In (a), cut from the corresponding cutting position on the panel. Figure 5 When cutting the flexible circuit board 200 as shown, more panel sizes are cut in the X-axis direction and fewer panel sizes are cut in the Y-axis direction, resulting in low panel utilization, which obviously contradicts the need to control costs.

[0138] and Figure 4 In the flexible circuit board 200 shown, the first end 220a of the second plate portion 220 fixes the second end 210b of the first plate portion 210, and the second end 220b of the second plate portion 220 extends 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. It can be seen that... Figure 4 In the illustrated embodiment, the second plate portion 220 does not continue to extend along the X-axis direction from the second end 210b of the first plate portion 210 and is arranged with the first plate portion 210 in the X-axis direction. Instead, it extends towards 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 panel. Figure 4 When the flexible circuit board 200 is shown, the panel sizes cut in the X-axis direction and the Y-axis direction are more balanced, thereby improving the utilization rate of the panels. According to statistics, this allows the flexible circuit board 200 to achieve a cost benefit of 1.5 RMB.

[0139] As a non-limiting embodiment, please continue to refer to Figure 4 The first plate portion 210 is constructed in the shape of a long strip. In this case, the X-axis direction can be the length direction of the first plate portion 210, and the Y-axis direction can be the width direction of the first plate portion 210.

[0140] It should be noted that when the first plate portion 210 is elongated and the X-axis direction is the length direction of the first plate portion 210, the following is adopted: Figure 5 The flexible circuit board 200 shown exhibits a more pronounced problem of low panel utilization. The design scheme described above, which extends 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 panel utilization, and the improvement effect on the low panel utilization 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 making reasonable use of the length dimension of the battery body 100 to extend the elongated first plate portion 210, the utilization rate of the battery 005 within the internal space of the electronic device 000 can be improved. Of course, in some other embodiments, the length direction of the first plate portion 210 may 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 of the second plate portion 220 to the main board 006.

[0142] As a non-limiting embodiment, please continue to 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 extends a first distance D1 along a first orientation in the first direction (as shown in the positive X-axis direction) to obtain a first sub-plate portion, then bends and extends a second distance D2 in the Y-axis direction to obtain a second sub-plate portion, and then bends and extends a third distance D3 in a second orientation in the first direction (as shown in the negative X-axis direction) to obtain a third sub-plate portion. The second plate portion 220 is approximately U-shaped with uneven left and right sides. The third distance D3 is greater than the first distance D1. The first orientation and the second orientation are opposite, with the first orientation being the direction from the first end of the first plate portion 210 to the second end.

[0143] Figure 4 In this embodiment, the orientation of the first end 210a of the first plate portion 210 towards the second end 210b is the positive X-axis direction, that is, the first orientation of the first direction is the positive X-axis direction. It can be understood that in some other embodiments, the first orientation of the first direction is the positive X-axis direction, and the second orientation of the first direction is the negative X-axis direction. Subsequent embodiments will be described using the example of the first orientation of the first direction being the positive X-axis direction and the second orientation of the first direction being the negative X-axis direction.

[0144] In this embodiment, since the positive and negative X-axis directions are opposite, the second end 220b of the second plate portion 220 extends in the positive X-axis direction and then folds back in the negative X-axis direction. With the third distance D3 greater than the first distance D1, and combined with the second distance D2 extending in the Y-axis direction, it extends to one side of the first plate portion 210 in the Y-axis direction. Based on the foregoing analysis, extending the second end 220b of the second plate portion 220 to one side of the first plate portion 210 in the Y-axis direction helps to balance the panel sizes cut in the X-axis and Y-axis directions, 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 may 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 this. Figure 4 An illustrative method. For example... Figure 8 Two optional implementations are provided.

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

[0147] Figure 8 In (a), the first end 220a of the second plate portion 220 fixes the second end 210b of the first plate portion 210 (specifically, it fixes the side 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 bends and extends a certain distance from the first end 220a of the second plate portion 220 along the Y-axis direction, and then bends and extends 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 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 obliquely 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 actual implementation, the second end 220b of the second plate portion 220 can 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] The following is about Figure 2 The assembly method of the battery 005 in the electronic device 000 shown is illustrated by way of example.

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

[0152] The assembly method uses a center alignment algorithm to assemble battery 005 to battery position 031 of electronic device 000. Specifically, it aligns the centerline of battery body 100 (as shown in the figure, the centerline O2 of battery body 100 in the X-axis direction) with the centerline of battery position 031 (as shown in the figure, the centerline O1 of battery position 031 in the X-axis direction). This assembly method uses the positions on battery body 100 and battery position 031 as reference positions for battery 005 assembly. This leads to the accumulation of tolerances such as incoming material tolerances and assembly tolerances. When battery 005 moves to battery position 031, it causes misalignment between BTB connector male socket 230 and BTB connector female socket 061.

[0153] for example, Figure 9 In the X-axis direction, the accumulated tolerance causes misalignment between the male connector 230 and the female connector 061 of the BTB connector 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 X-axis direction, in which case the flexible circuit board 200 is redundant in the X-axis direction. Figure 9 (b) shows the case where the BTB connector male socket 230 is misaligned relative to the BTB connector female socket 061 in the positive X-axis direction, in which case the flexible circuit board 200 is insufficient in length 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 motherboard 006 are misaligned in the X-axis direction, forcibly connecting the BTB connector male socket 230 of the battery 005 and the BTB connector female socket 061 of the motherboard 006 may result in the following two situations for the flexible circuit board 200:

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

[0156] Second, corresponding to Figure 9 (b) in the example Figure 10As shown in (b), the flexible circuit board 200 is stretched due to insufficient length in the X-axis direction. Combined with... Figure 2 When the flexible circuit board 200 is stretched, it is easy for the flexible circuit board 200 to tear or for the BTB connector male socket 230 and BTB connector female socket 061 to not be securely fastened, thereby reducing the reliability of the electrical connection between the battery 005 and the motherboard 006.

[0157] It should be noted that in some other embodiments, the battery 005 may also be assembled by aligning the center line of the battery body 100 in the Y-axis direction with the center line of the battery position 031 in the Y-axis direction. In this case, the aforementioned tolerance will cause misalignment of the BTB connector male socket 230 and the BTB connector female socket 061 in the Y-axis direction. Misalignment of the BTB connector male socket 230 and the BTB connector female socket 061 in the Y-axis direction can also easily cause the flexible circuit board 200 to bulge or be stretched, thus causing the aforementioned problems.

[0158] Based on this, in order to solve the above-mentioned problems caused by the misalignment of the BTB connector male socket 230 and the BTB connector female socket 061, resulting in the arching or stretching of the flexible circuit board 200, this application provides two solutions.

[0159] First, let's explain the first solution.

[0160] The first solution is a new assembly method for battery 005, which can be used to achieve... Figure 2 The assembly of battery 005 in the electronic device 000 shown below. (Followed by...) Figure 11 and Figure 12 Please provide an explanation.

[0161] For example, please refer to Figure 11 , Figure 11 This is a flowchart illustrating a method for assembling a battery 005 according to an embodiment of this application, which is applied in mechanical equipment for assembling a battery 005. Figure 12 for Figure 11 The assembly method shown corresponds to the structural assembly diagram. Figure 1 . Figure 11 The assembly method shown includes the following steps S101 to S104.

[0162] Step S101: Install the motherboard to one side of the battery compartment.

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

[0164] also, Figure 12 In the diagram, battery 005's current position is indicated by the solid line, located on one side of battery position 031 along the Y-axis, corresponding to the position of battery position 031 along the Y-axis. Combined with... Figure 12 The position of battery position 031 in the Y-axis direction is: the position between the reference lines where the two relative edge lines of battery position 031 are located in the X-axis direction, that is, the position between reference line P1 and 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 corresponding positions of battery position 031 in the X-axis and Z-axis directions. For example, in some other embodiments, the current position of battery 005 can 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. Therefore, the current position of battery 005 at battery position 031 also falls under the category of the battery being located at the position corresponding to battery position 031 in the Y-axis direction. The definitions of the positions corresponding to battery position 031 in the Y-axis direction and the Z-axis direction can be found by referring to the meaning of 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 in the X-axis direction, or in the Z-axis direction, and so on. This application does not limit this aspect.

[0167] Step S102: Obtain the first position of the flexible circuit board of the battery and the second position of the main board.

[0168] In specific implementation, step S101 may include a robotic arm that holds the battery and a camera mounted on the robotic arm, such as a charge-coupled device (CCD) camera. As the robotic arm moves while holding the battery, it continuously takes photos using the mounted camera. The image sensor (e.g., CCD) of the camera captures photos of the flexible circuit board containing the battery and the motherboard. Figure 12 Image recognition is performed on the photo corresponding to the shown viewpoint to obtain the first and second positions mentioned above.

[0169] The aforementioned first position is used to characterize the position of the BTB connector male socket on 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 as the first position to characterize the BTB connector male socket on 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 (i.e., the first direction), the first position is the side edge S1 of the second plate portion 220 facing away from the first plate portion 210.

[0172] It should be noted that the first end of the second plate portion 220 is called the fixed end because it fixes the second end of the first plate portion 210, and the second end of the second plate portion 220 is the free end before the BTB connector male socket 230 is electrically connected to the BTB connector female socket 061. Because the second plate portion 220 is a flexible structure, the closer the second plate portion 220 is to the free end in the X-axis direction, the easier it is to move. Using this as a reference position during assembly can easily cause misalignment of the BTB connector male socket 230 and the BTB connector female socket 061 in the X-axis direction, thus preventing electrical connection between them. Therefore, the position of the second plate portion 220 closer to the free end in the X-axis direction is less suitable as the first position.

[0173] In this embodiment, since 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 characterize 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, which is equivalent to selecting the position of the second plate portion 220 furthest from the free end in the X-axis direction as the first position. This position is less prone to movement compared to other positions on the second plate portion 220, and has a smaller impact on the misalignment of the BTB connector male socket 230 and the BTB connector female socket 061 in the X-axis direction.

[0174] Of course, in some other embodiments, the first position is not limited to edge S1. For example, please refer to... Figure 12 When the first plate portion 210 of the flexible circuit board 200 is a rigid structure, the first position can also be a position on the first plate portion 210. For example, the first position can be... Figure 12 The schematic diagram shows the edge S2 of the first plate portion 210, the edge S3 of the first plate portion 210, etc.

[0175] The position and shape of the first plate portion 210, which is a rigid structure, are not easily changed. The position on the first plate portion 210, which is a rigid structure, is selected to represent the first position of the BTB connector male socket 230 as a reference position during assembly. This has little impact 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 indicated location may be any other location on the flexible circuit board 200 in other embodiments.

[0177] The aforementioned second position is used to characterize the position of the BTB connector female on the motherboard. It should be noted that a position on the motherboard that is not easily moved relative to the BTB connector female can be used to characterize the second position of the BTB connector female on the motherboard.

[0178] As a non-limiting embodiment, to facilitate image recognition, the second location can be selected as the edge of a certain area on the motherboard. Because the edge has a clear boundary with its surroundings, it can serve as a feature for image recognition, thereby locating the second location more quickly. For example, the second location could be the edge of a copper-blind area on the motherboard. Figure 12 The second position is defined as one edge S4 of the two edges of the copper leakage area 062 arranged in the X-axis direction.

[0179] Because the copper-exposed area 062 of the motherboard 006 has a significant color difference compared to other areas of the motherboard 006 (the motherboard 006 is usually green), it is easily distinguishable during image recognition. Therefore, in this embodiment, the edge of the copper-exposed area 062 of the motherboard 006 is used as the second location, which is easily identified during image recognition, thus facilitating the 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 location may be any other location on the motherboard 006 in other embodiments.

[0181] Step S103: Assemble the battery to the target position of the battery compartment according to the first position and the second position. The target position of the battery compartment is the position where the male and female BTB connectors correspond to each other.

[0182] Please refer to the reference. Figure 12The BTB connector male socket 230 and BTB connector female socket 061 correspond to each other, which can be in the X-axis direction and / or Y-axis direction. Correspondence between the BTB connector male socket 230 and BTB connector female socket 061 in a certain direction means that the BTB connector male socket 230 and BTB connector female socket 061 are not misaligned in that direction, or the misalignment is small enough that the bulging or pulling phenomenon of the flexible circuit board 200 caused by the BTB connector male socket 230 fastening the BTB connector female socket 061 is not obvious and insufficient to resist the screen or back cover. The threshold for this misalignment can be set as needed.

[0183] It should be noted that the BTB connector male socket 230 and the BTB connector female socket 061 are considered to be corresponding in the X-axis direction and / or Y-axis direction, respectively, based on the first position and the second position. In this case, step S103 is equivalent to: assembling the battery to the target position where the BTB connector male socket and the BTB connector female socket correspond in the X-axis direction and / or Y-axis direction, according to the first position and the second position.

[0184] Figure 12 In this case, because 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 minor, 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] Therefore, as a non-limiting embodiment, Figure 12 In this context, 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 (i.e., the first direction). In this case, step S103 is as follows: based on the first and second positions, 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. For example, Figure 12 In the process, according to edge S1 and edge S4, battery 005 is assembled to the target position so that BTB connector male socket 230 and BTB connector female socket 061 correspond in the X-axis direction.

[0186] Step S103, assembling the battery to the target location of the battery compartment, may involve moving the battery from its current location to the target location. For example, Figure 12In the case where the battery is located at the position indicated by the dashed line within the battery position 031 shown in the figure, the BTB connector male socket 230 and the BTB connector female socket 061 correspond to each other. Therefore, the target position can be the battery position indicated by the dashed line within the battery position 031 shown in the figure. In this case, in step S103, the battery 005 moves from the current position indicated by the solid line shown in the figure to the target position indicated by the dashed line within the battery position 031 shown in the figure.

[0187] Depend on Figure 12 It is evident that moving the battery 005 to the target position of the battery position 031 does not require all components of the battery 005 to move into the battery position 031. For example, moving the battery 005 to the target position of the battery position 031 may involve the main body of the battery 005 moving to the target position of the battery position 031 while a portion of the flexible circuit board 200 extends out of the battery position 031. Furthermore, 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 fixing the battery 005. This application embodiment does not limit these steps.

[0188] Step S104: Connect the male and female BTB connectors to achieve electrical connection.

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

[0190] Compared to methods that characterize the position of the BTB connector male socket 230 using structures other than the flexible circuit board 200 (such as the center line of the battery 005 used in the relevant assembly method) and the position of the BTB connector female socket 061 using structures other than the motherboard 006 (such as the center line of the battery position 031 used in the relevant assembly method), 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 motherboard 006 where the BTB connector female socket 061 is located. Since the incoming material tolerances of the battery position 031, the incoming material tolerances of the battery 005 body, the assembly tolerances between the battery position 031 and the battery 005 body, and the assembly tolerances between the battery 005 body and the flexible circuit board 200 are not introduced, the first position and the second position can more accurately characterize the position of the BTB connector male socket 230 and the position of the BTB connector female socket 061, respectively.

[0191] Based on this, compared with related assembly methods, using the first position of the flexible circuit board 200 of the battery 005 and the second position of the main board 006 as reference positions during assembly has a smaller impact on the misalignment of the BTB connector male socket 230 and the BTB connector female socket 061. This can improve the misalignment of the BTB connector male socket 230 and the BTB connector female socket 061 in one or more directions, so that the BTB connector male socket 230 and the BTB connector female socket 061 correspond to each other in one or more directions. When the BTB connector male socket 230 and the BTB connector female socket 061 correspond in one or more directions, fastening the BTB connector male socket 230 and the BTB connector female socket 061 can improve the arching or pulling phenomenon of the flexible circuit board 200. This can solve reliability problems such as white spots on the screen 001 caused by the arching of the flexible circuit board 200, or appearance problems such as the arching of the corresponding area of ​​the back cover 002. It can also solve the tearing or poor contact problems caused by the pulling of the flexible circuit board 200, thereby improving the electrical connection reliability between the battery 005 and the motherboard 006.

[0192] In addition, regarding Figure 12 When assembling the battery 005 to the target position where the BTB connector male socket 230 and BTB connector female socket 061 correspond in the X-axis direction, because the BTB connector male socket 230 and BTB connector female socket 061 correspond in the X-axis direction, when the BTB connector male socket 230 and BTB connector female socket 061 are fastened together, it is less likely that the flexible circuit board 200 will bulge due to redundancy in the X-axis direction, or be pulled due to insufficient length in the X-axis direction, thus solving the problem. Figure 10 The aforementioned problem.

[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. Based on this, even with Figure 5 The flexible circuit board 200 shown uses a battery 005. Figure 9 The assembly can be performed using the relevant assembly method shown. Alternatively, the position of the BTB connector male socket 230 in the X-axis direction of the second board 220 can be adjusted so that the BTB connector male socket 230 and the BTB connector female socket 061 can be engaged without the flexible circuit board 200 arching or being pulled.

[0194] However, compared to Figure 5 Regarding the flexible circuit board 200 shown, because Figure 4The flexible circuit board 200 shown is not a double-layer structure bent 180° in the X-axis direction. The second plate portion 220 of the flexible circuit board 200 cannot move relative to the first plate portion 210 in the X-axis direction, thus making it impossible to adjust the position of the BTB connector male socket 230 of the second plate portion 220 in the X-axis direction. Based on this, when using… Figure 9 The relevant assembly method shown will Figure 2 When battery 005 moves to battery position 031, the position of the BTB connector male socket 230 of the second board 220 in the X-axis direction cannot be adjusted. Therefore, the misalignment between the BTB connector male socket 230 of battery 005 and the BTB connector female socket 061 of motherboard 006 in the X-axis direction cannot be corrected, resulting in a failure to achieve electrical connection between the BTB connector male socket 230 of battery 005 and the BTB connector female socket 061 of motherboard 006. Based on this, Figure 2 Battery 005 is suitable for use Figure 11 The assembly method shown improves the misalignment of the first electrical connection and the second electrical connection in the X-axis direction.

[0195] It should be noted that, Figure 11 The assembly method of the battery 005 shown can also be used to assemble the battery 005 in other electronic devices 000, for example, for use in other electronic devices 000 with... Figure 5 The battery 005 is assembled on the flexible circuit board 200 shown. In this case, it is not necessary to improve the misalignment of the BTB connector male socket 230 and the BTB connector female socket 061 in the X-axis direction by adjusting the position of the second board portion 220 in the X-axis direction.

[0196] The following will 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 in the X-axis direction as an example, step S103 will be explained in detail.

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

[0198] Step S1031: Determine 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 Taking the first position as edge S1 and the second position as edge S4 as an example, 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 edge S1 along the Y-axis direction and the X coordinate of the second reference line L2 passing through 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 and second positions in the diagram correspond to edges S1 and S4 extending along the Y-axis. Therefore, the first reference line L1 extending along the Y-axis coincides with edge S1, and the second reference line L2 extending along the Y-axis coincides with edge S4. In other embodiments, the first and second positions take other forms. For example, the first and second positions can also be the positions corresponding to two points, in which case the first reference line passes through one of these two points along the Y-axis, and the second reference line passes through the other point along the Y-axis. Alternatively, the first and second positions can also be the positions corresponding to two irregular shapes, in which case the first reference line passes through a point on one of the shapes along the Y-axis, and the second reference line passes through a point on the other shape along the Y-axis.

[0202] Figure 12 In this process, since it is necessary to obtain the actual distance △L1 between the first position and the second position in the X-axis direction, when selecting the first position, the side edge S1 of the second plate portion 220 facing away from the first plate portion 210 in the X-axis direction is taken as the first position; when selecting the second position, the side edge S2 of the copper leakage area 062 in the X-axis direction is taken as the second position. This helps to obtain the actual distance △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 in the X-axis direction.

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

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

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

[0206] The execution order of steps S1031 and S1032 is not important. Figure 12 In this example, taking the battery position indicated by the solid line as offset in the negative X-axis direction relative to the battery position indicated by the dashed line outside battery position 031, the actual spacing △L1 and the designed spacing △L3 are explained. In this case, the actual spacing △L1 is greater than the designed spacing △L3. In some other embodiments, such as... Figure 13 As shown, the battery position indicated by the solid line can also be offset in the positive X-axis direction relative to the battery position indicated by the dashed line outside battery position 031. In this case, the actual spacing △L1 is smaller than the designed spacing △L3, or, as... Figure 14 As shown, the battery position indicated by the solid line can also be without offset in the X-axis direction relative to the battery position indicated by the dashed line located outside battery position 031. In this case, the actual spacing △L1 is equal to the design spacing △L3. This application embodiment does not limit this.

[0207] Step S1033: Assemble the battery into the target position of the battery compartment according to the actual spacing and the design spacing.

[0208] Step S1033 differs depending on whether the actual spacing and the designed spacing are equal, and will be discussed in detail below.

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

[0210] Since the design spacing is the distance 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 characterize the misalignment of the BTB connector male socket 230 and the BTB connector female socket 061 in the X-axis direction.

[0211] The relationship between the actual spacing and the designed spacing characterizes the misalignment orientation of the BTB connector male socket 230 and the BTB connector female socket 061 in the X-axis direction. Moving the battery 005 in the opposite direction of the misalignment orientation (referred to as the moving orientation in this embodiment) can improve the misalignment of the BTB connector male socket 230 relative to the BTB connector female socket 061 in the X-axis direction, thus ensuring that the BTB connector male socket 230 and the BTB connector female socket 061 correspond 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, when the battery 005 is assembled from its current position to the target position, it moves along the moving direction in the X-axis direction. Since the relationship between the actual spacing and the designed spacing can characterize the above-mentioned misalignment direction, and the opposite direction of the misalignment direction is the moving direction, the moving 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 characterizes the misalignment of the BTB connector male socket 230 and the BTB connector female socket 061 in the X-axis direction. This misalignment is equal to the required movement of the battery 005 in the X-axis direction if the BTB connector male socket 230 and the BTB connector female socket 061 were not misaligned. 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 it based on the required movement, thus helping to ensure that the BTB connector male socket 230 and the BTB connector female socket 061 correspond in the X-axis direction.

[0214] Continue with Figure 12 Example Figure 12 This illustrates a situation where the actual spacing is greater 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 dashed line outside battery position 031, resulting in an actual spacing greater than the designed spacing. Furthermore, the BTB connector male socket 230 is misaligned relative to the BTB connector female socket 061 in the negative X-axis direction. In this case, the misalignment of the BTB connector male socket 230 relative to the BTB connector female socket 061 in the X-axis direction is in the negative X-axis direction (i.e., the first misalignment direction is in the negative X-axis direction). Therefore, Figure 12 In the diagram, the actual spacing is greater than the designed spacing, which indicates that the aforementioned misalignment is in the negative X-axis direction. Battery 005, assembled from its current position (indicated by the solid line) to the target position (indicated by the dashed line) within battery position 031, needs to move along the positive X-axis direction; that is, the movement direction is the positive X-axis direction (i.e., the first movement direction is the positive X-axis direction).

[0216] It should be noted that the first misalignment orientation and the first movement orientation are opposite. The first misalignment orientation is one of the first orientation and the second orientation of the first direction, and the first movement orientation is the other of the first orientation and the second orientation of the first direction. Figure 12 In the diagram, the positive X-axis direction represents the first orientation of the first direction, and the negative X-axis direction represents the second orientation of the first direction. Based on this... Figure 12 This illustrates a scenario where the first misalignment orientation is a second orientation relative to the first direction, and the first movement orientation is a first orientation relative to the first direction. In some other embodiments, the first misalignment orientation may also be a first orientation relative to the first direction, and the first movement orientation may also be a second orientation relative to the first direction.

[0217] visible, Figure 12 In this context, the relationship between the actual deviation and the design deviation represents the opposite of the first misalignment orientation and the first movement orientation. Based on this, the movement orientation can be determined based on the relationship between the actual deviation and the design deviation.

[0218] and, Figure 12 In the diagram, the difference between the actual spacing and the designed spacing is △L13 (△L13 in the diagram is the difference between the X-coordinate of the first reference line L1 and the X-coordinate of the third reference line L3). The misalignment of the BTB connector male socket 230 and the BTB connector female socket 061 in the X-axis direction is the absolute value of △L45 (△L45 in the diagram is the difference between the X-coordinate of the fourth reference line L4 and the X-coordinate of the fifth reference line L5). The absolute value of △L13 is approximately equal to the absolute value of △L45. Therefore, the absolute value of the difference between the actual spacing and the designed spacing can characterize the misalignment of the BTB connector male socket 230 and the BTB connector female socket 061 in the X-axis direction, which is also the required movement amount mentioned above. Based on this, the target movement amount △P (the spacing between reference lines P3 and P5) can be determined based on the absolute value of the difference between the actual spacing and the designed spacing.

[0219] In some other embodiments, such as Figure 13 As shown, Figure 13 This illustrates a situation where the actual spacing is less than the designed spacing.

[0220] In the X-axis direction, the battery position indicated by the solid line is offset in the positive X-axis direction relative to the battery position indicated by the dashed line outside battery position 031, resulting in an actual spacing greater than the designed spacing. Furthermore, the BTB connector male socket 230 is misaligned relative to the BTB connector female socket 061 in the positive X-axis direction. In this case, the misalignment of the BTB connector male socket 230 relative to the BTB connector female socket 061 in the X-axis direction is towards the positive X-axis direction (i.e., the second misalignment direction is towards the positive X-axis direction). Therefore, Figure 13 In the diagram, the actual spacing is less than the designed spacing, which indicates that the aforementioned misalignment is oriented in the positive X-axis direction. Battery 005, assembled from its current position (indicated by the solid line) to its target position (indicated by the dashed line) within battery position 031, needs to move along the negative X-axis direction; that is, the movement direction is the negative X-axis direction (i.e., the second movement direction is the negative X-axis direction).

[0221] The second misalignment orientation is opposite to the second movement orientation. The second misalignment orientation is the other of the first orientation and the second orientation in the first direction, and the second movement orientation is one of the first orientation and the second orientation in the first direction. The second misalignment orientation is opposite to the first misalignment orientation, and the second movement orientation is opposite to the first movement orientation. Figure 13 In the diagram, the positive X-axis direction represents the first orientation of the first direction, and the negative X-axis direction represents the second orientation of the first direction. Therefore... Figure 13 This illustrates a scenario where the second misalignment orientation is the first orientation of the first direction and the second movement orientation is the second orientation of the first direction. In some other embodiments, the second misalignment orientation may also be the second orientation of the first direction and the second movement orientation may also be the first orientation of the first direction.

[0222] It is evident that the relationship between the actual deviation and the design deviation indicates that the second misalignment orientation is opposite to the second movement orientation. Based on this, the movement orientation can be determined based on the relationship between the actual deviation and the design deviation.

[0223] and, Figure 13In the diagram, the difference between the actual spacing and the designed spacing is △L13 (△L13 in the diagram is the difference between the X-coordinate of the first reference line L1 and the X-coordinate of the third reference line L3). The misalignment of the BTB connector male socket 230 and the BTB connector female socket 061 in the X-axis direction is the absolute value of △L45 (△L45 in the diagram is the difference between the X-coordinate of the fourth reference line L4 and the X-coordinate of the fifth reference line L5). The absolute value of △L13 is approximately equal to the absolute value of △L45. Therefore, the absolute value of the difference between the actual spacing and the designed spacing can characterize the misalignment of the BTB connector male socket 230 and the BTB connector female socket 061 in the X-axis direction, which is also the required movement amount mentioned above. Based on this, the target movement amount △P (the spacing between reference lines P3 and P5) can be determined based on the absolute value of the difference between the actual spacing and the designed spacing.

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

[0225] Since the design spacing is the distance 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 assembly of the battery 005 to the target position, this embodiment keeps the battery 005 stationary in the X-axis direction, thereby maintaining the misalignment of the BTB connector male socket 230 and the BTB connector female socket 061 in the X-axis direction, and assembling 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.

[0226] For example, such as Figure 14 As shown, Figure 14 This illustrates the case where the actual spacing △L1 is equal to the design spacing △L3.

[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 dashed line outside battery position 031, ensuring that the actual spacing equals the design 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). Therefore, Figure 14In this embodiment, the actual spacing equals the design 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, while maintaining the position of the battery 005 in the X-axis direction, this embodiment moves the battery 005 to the battery position 031, thus assembling the battery 005 to the target position.

[0228] Figures 12 to 14 In the diagram, the solid line indicates the battery position located on one side of battery position 031 in the Y-axis direction, not actually within battery position 031. Therefore, in step S1033, assembling battery 005 to the target position indicated by the dashed line within battery position 031 involves moving battery 005 to the target position indicated by the dashed line within battery position 031 and assembling it. For Figures 12 to 13 In the illustrated embodiment, moving battery 005 to the target position indicated by the dashed line within battery position 031 involves movement along the X-axis, Y-axis, and Z-axis directions; for Figure 14 In the illustrated embodiment, since the movement does not occur in the X-axis direction, moving the battery 005 to the target position indicated by the dashed line within the battery position 031 involves movement in both the Y-axis and Z-axis directions. This application embodiment does not impose special limitations on the specific process of moving the battery 005 to the target position indicated by the dashed line within the battery position 031. For example, Figure 12 In the process, battery 005 can first move in the Y-axis direction, then in the X-axis direction, and finally in the Z-axis direction, thereby moving to the target position indicated by the dotted line within battery position 031; alternatively, it can first move in the X-axis direction, then in the Y-axis direction, and finally in the Z-axis direction, thereby moving to the target position indicated by the dotted line within battery position 031.

[0229] In some other embodiments, the battery position indicated by the solid line is located at battery position 031. When the actual spacing is not equal to the designed spacing, the current position and target position of battery 005 are only separated by the X-axis direction; therefore, assembling battery 005 to the target position involves moving battery 005 to the target position and assembling it in the X-axis direction. When 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 is combined Figure 15 Taking the current position of the battery as the battery position as an example, for... Figure 11 Step S1033 is explained in detail.

[0231] For example, please refer to Figure 15 , Figure 15 This is a schematic diagram of a battery assembly scheme provided in an embodiment of this application. The battery assembly scheme includes the following steps S1033a to S1033d3.

[0232] S1033a, determine the relationship between the actual spacing and the design spacing.

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

[0234] If the actual spacing is less than the design spacing, a second movement orientation compensation algorithm is executed. The second movement orientation compensation algorithm includes steps S1033b2, S1033c2, S1033d2, and S1033e.

[0235] If the actual spacing is equal to the design spacing, proceed to step S103e.

[0236] Step S1033b1: Determine the movement direction as the first movement direction.

[0237] Step S1033c1: Determine the target movement amount.

[0238] The execution order of steps S1033b1 and S1033c1 is not important.

[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 direction. 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 direction ensures that the battery does not fall out of the battery position and cannot be assembled.

[0240] Depending on the different relationships between the required movement amount and the first movable amount, step S1033c1 specifically includes the following three cases:

[0241] The first scenario: If 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 scenario: When the demand movement amount equals the first movable amount, the demand movement amount (i.e., the first movable amount) is determined as the target movement amount.

[0243] The third scenario: If the required movement amount is greater than the first movable amount, the first movable amount is determined as the target movement amount.

[0244] In some embodiments, such as Figure 12As shown, with the battery in its 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 collinear. In this case, the first movable amount is (AB) / 2. Where A is the accommodating 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 specific implementation, the following can be adopted: Figure 9 The assembly method shown moves battery 005 to its current position where center line O1 and center line O2 are on the same straight line.

[0245] Typically, electronic device 000 is designed to meet the following conditions: When the BTB connector male socket 230 and BTB connector female socket 061 are not misaligned in the X-axis direction, the center line O1 of battery position 031 in the X-axis direction and the center line O2 of battery body 100 in the X-axis direction are collinear. This allows battery 005 to be assembled into battery position 031 in a relatively centered position, resulting in a more balanced weight distribution of electronic device 000 in the X-axis direction. With center lines O1 and O2 collinear, the gap between battery position 031 and battery body 100 on one side of center line O1 is (AB) / 2. Based on this, the amount of movement that battery position 031 can provide to 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 some embodiments, when the battery is located at the current position indicated by the solid line, the center line O1 of the battery position 031 may not be collinear with the center line O2 of the battery body 100. In this case, the first movable amount is the distance ΔP32 between the reference line P2 where one edge of the battery position 031 is located in the positive X-axis direction and the reference line P3 where one edge of the battery body 100 is located in the positive X-axis direction. Since the center line O1 and the center line O2 of the battery body 100 are collinear in the figure, ΔP32 = (AB) / 2.

[0247] Step S1033d1: The battery is assembled after being moved a first distance in the first direction toward the target location. If the battery's current position is the battery position, the battery is moved a first distance in the first direction toward the target location until it reaches the target position of the battery position.

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

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

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

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

[0252] In some other embodiments, if the required movement amount is greater than the first movable amount, the battery may also be considered a defective product and discarded (i.e., the battery is not assembled).

[0253] Step S1033b2: Determine the movement direction as the second movement direction.

[0254] Step S1033c2: Determine the target movement amount.

[0255] The execution order of steps S1033b2 and S1033c2 is not important.

[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 that the battery position can provide to the battery in the second movement direction. 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 direction ensures that the battery does not fall out of its position and cannot be assembled.

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

[0258] The first scenario: If the required movement amount is greater than the second movable amount, the second movable amount is determined as the target movement amount.

[0259] The second scenario: When the demand movement amount equals the second movable amount, the demand movement amount (i.e., the second movable amount) is determined as the target movement amount.

[0260] The third scenario: If 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, such as Figure 13 As shown, with battery 005 in its current position indicated by the solid line, center lines O1 and O2 are on the same straight line. In this case, the second movable amount is (AB) / 2. For a detailed analysis, please refer to the relevant explanation of the first movable amount being (AB) / 2.

[0262] In some embodiments, when the battery is located at the current position indicated by the solid line, the center line O1 of the battery position 031 may not be collinear with the center line O2 of the battery body 100. In this case, the second movable amount is the distance ΔP41 between the reference line P1 where one edge of the battery position 031 is located in the negative X-axis direction and the reference line P4 where one edge of the battery body 100 is located in the negative X-axis direction. Since the center line O1 and the center line O2 of the battery body 100 are collinear in the figure, ΔP41 = (AB) / 2.

[0263] Step S1033d2: The battery is moved along the second movement in the first direction towards the target movement amount and then assembled. If the current position of the battery is the battery position, the battery is moved along the second movement in the first direction towards the target movement amount until it reaches the target position of the battery position.

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

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

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

[0267] Case 3 (corresponding to the third case): After moving battery 005 along the second moving direction in the first direction by the required amount, it is assembled.

[0268] In some other embodiments, if the required movement amount is greater than the second movable amount, the battery may also be considered a defective product and discarded (i.e., the battery is not assembled).

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

[0270] Next, the second solution will be explained. The second solution is: In Figure 1 and Figure 2 The electronic device 000 shown is equipped with a pressure plate. Figure 4 The deformable area of ​​the second board portion 220 is flattened to reduce the risk of the flexible circuit board 200 arching or being stretched.

[0271] For example, please refer to Figure 16 , Figure 16 This is a schematic diagram of the easily deformable area of ​​the pressure plate provided in the embodiments of this application.

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

[0273] In this embodiment, by attaching a pressure plate 007 to the side of the deformable area 221 facing away from the motherboard 006, and using a fastener 008 to fix the pressure plate 007 to the deformable area 221, the force exerted by the fastener 008 in the thickness direction (Z-axis direction in the figure) of the pressure plate 007 can be used to make the pressure plate 007 adhere to the plate surface of the deformable area 221, flattening the deformable area 221. This solves the reliability problems such as white spots on the screen 001 caused by the deformable area 221 arching away from the motherboard 006, or the appearance problems of bulging in the corresponding area of ​​the back cover 002.

[0274] Optionally, the pressure plate 007 can be a steel sheet with a thickness of 0.25mm. This thickness of steel sheet has strong bending resistance and is not easily bent by the flexible circuit board 200, reducing the risk of the flexible circuit board 200 arching or being pulled.

[0275] Accordingly, embodiments of this application also provide a method for assembling a battery 005, for use with Figure 16 The assembly of the battery 005 of the electronic device 000 shown in the pressure plate 007.

[0276] For example, please refer to the reference Figure 17 , Figure 17 This is a flowchart illustrating another method for assembling a battery 005 provided in an embodiment of this application, which is applied to mechanical equipment for assembling a battery 005; Figure 18 for Figure 17 The assembly method shown is illustrated in the structural assembly diagram. Figure 18 The perspective of the display is roughly as follows Figure 16 The cross-sectional view obtained by cutting through the section line QQ.

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

[0278] Step S201: Move the battery to the battery position and extend the flexible circuit board of the battery to the side of the motherboard to electrically connect to the motherboard through the flexible circuit board.

[0279] Among them, the area where the flexible circuit board 200 extends to the side of the main board 006 is the easily deformable area 221.

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

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

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

[0283] Step S203: Use the 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 main board.

[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 two fixed positions of the pressure plate 007. The fixed positions are used to install the fastener 008.

[0285] It should be noted that the deformation area is flattened on the surface of motherboard 006, which means that the easily deformable area 221 is approximately 180° on the surface of motherboard 006. Figure 18 In the middle, 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 the cover plate 009 to push the pressure plate 007 toward the side where the easily deformable area 221 is located refers to the process of the cover plate 009 pressing the pressure plate 007 downwards, as shown by the arrow in the figure. Because during the process of the cover plate 009 pressing the pressure plate 007 downwards, the pressure head 010 contacts the pressure plate 007 first.

[0287] As a non-limiting embodiment, the indenter 010 has a Rockwell hardness of 50 to 60 HR. Exemplarily, the indenter 010 can be made of soft silicone material with a Rockwell hardness of 50 to 60 HR. In this case, during the pressing process, the indenter 010 makes soft contact with the pressure plate 007, making it less likely to damage the pressure plate 007. Furthermore, the indenter with a Rockwell hardness of 50 to 60 HR is a soft material, easily deformable during pressing to allow the cover plate 009 to contact the pressure plate 007, thereby pushing the pressure plate 007 to flatten the deformable area 221 on the surface of the main plate 006.

[0288] Figure 18 In the middle, the fixing position 071 can be a threaded hole, and correspondingly, the fixing part 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 pressure heads 010 shown is one, and the number of fixing positions 071 on the pressure plate 007 is two. In other embodiments, there may be more pressure heads 010 and fixing positions 071 on the pressure plate 007. This application does not limit this.

[0290] In step S204, when the cover plate pushes the pressure plate to flatten the easily deformable area, a fixing member is set at each of the two fixing positions to fix the pressure plate to the main plate.

[0291] like Figure 18 As shown in (c), in order for the fastener 008 to fix the pressure plate 007 to the main plate 006, the main plate 006 has a threaded hole that corresponds to the threaded hole on the pressure plate 007. This allows fasteners such as bolts to pass through the threaded hole on the pressure plate 007 and extend into the threaded hole on the main plate 006 for locking, thereby fixing the pressure plate 007 to the main plate 006. After the fasteners are locked, the following is presented: Figure 18 The state shown in (d) is as follows.

[0292] In related technologies, the cover plate 009 lacks a pressure head 010. When the pressure plate 007 is fixed using two fasteners 008, the deformable area 221 between the two fixing positions 071 tends to arch away from the motherboard 006, causing reliability issues such as white spots on the screen or cosmetic problems such as bulging in the corresponding area of ​​the back cover. In this implementation, the pressure head 010 contacts and presses down on the pressure plate 007 before the cover plate 009. Based on this, when the deformable area 221 is fixed using two fasteners 008, the deformable area 221 between the two fixing positions 071 is held in place by the pressure head 010 and is less likely to arch, thus solving the reliability issues or cosmetic problems such as white spots on the screen caused by the deformable area 221 arching away from the motherboard 006.

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

[0294] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
