Description

Technical Field

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

[0002] As the demand for thinner and lighter electronic devices such as tablet computers and mobile phones increases, controlling the thickness of electronic devices has become a key research and development direction in the industry. If the thickness of electronic devices is too large, they will not meet the demand for thinner and lighter devices.

[0003] The flexible circuit board of the battery is cut from the substrate and is used to electrically connect to the mainboard to transmit power and battery status signals. In the case where the thickness of the flexible circuit board occupies the thickness space of the electronic device, the thickness of the electronic device can be reduced by reducing the thickness of the flexible circuit board, so that the electronic device can meet the demand for thinness and lightness.

[0004] However, the current flexible circuit boards for batteries cannot take into account both thickness and substrate utilization. Summary of the invention

[0005] The embodiment of the present application provides a flexible circuit board, a battery, an electronic device and a battery assembly method. The flexible circuit board can take into account both thickness and substrate utilization, and when the thickness is reduced, the substrate utilization is improved.

[0006] To achieve the above purpose, the embodiment of the present application adopts the following technical solution: In a first aspect, an embodiment of the present application provides a flexible circuit board. The flexible circuit board includes a first plate portion and a second plate portion. The first plate portion includes a first end and a second end disposed opposite to each other in a first direction, and the first direction is perpendicular to the thickness direction of the first plate portion. The second plate portion is a flexible structure. The first end of the second plate portion 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 the second direction. The second direction is perpendicular to the first direction and the thickness direction of the first plate portion. In the thickness direction of the first plate portion, the second plate portion and the first plate portion do not overlap, that is, the orthographic projections of the first plate portion and the second plate portion along the thickness direction do not overlap.

[0007] In the related art, the second plate portion of the flexible circuit board is bent 180° in the first direction to the plate surface side of the first plate portion (i.e., one side in the thickness direction of the first plate portion) for stacking to form a double-layer structure, so that the thickness of the flexible circuit board is relatively high. Before the second plate portion is bent, the first plate portion and the second plate portion of the flexible circuit board are arranged in the first direction. In order to obtain the flexible circuit board before bending, the substrate needs to be cut. Because the first plate portion of the flexible circuit board before bending extends in the first direction, and the second plate portion and the first plate portion are also arranged in the first direction, when the flexible circuit board is cut from the substrate, the size of the substrate cut in the first direction is larger and the size of the substrate cut in the second direction is smaller, resulting in a low utilization rate of the substrate.

[0008] In this flexible circuit board, the second board portion and the first board portion are not stacked in the thickness direction of the first board portion, and the formed flexible circuit board is a single-layer structure, and the thickness is lower than that of the related art. At the same time, the first end of the second board portion fixes the second end of the first board portion, and the second end of the second board portion extends from the first end of the second board portion to one side of the first board portion in the second direction. It can be seen that in this embodiment, the second board portion does not continue to extend along the first direction and is arranged with the first board portion in the first direction, but extends to one side of the first board portion in the second direction perpendicular to the first direction, which is conducive to balancing the size of the substrate cut in the first direction and the size of the substrate cut in the second direction, thereby improving the utilization rate of the substrate. It can be seen that the flexible circuit board provided by this embodiment improves the utilization rate of the substrate while reducing the thickness.

[0009] As a non-limiting embodiment, the first plate portion is configured as a long 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.

[0010] In this embodiment, when the first plate portion is configured as a long strip and the first direction is the length direction of the first plate portion, the low utilization rate of the substrate in the related technology is more obvious. Based on this, the above-mentioned design scheme of extending the second end of the second plate portion to one side of the first plate portion in the second direction can further improve the utilization rate of the substrate, and the improvement effect on the low utilization rate of the substrate is more significant.

[0011] As a non-limiting embodiment, after the second end of the second plate portion extends a first distance along a first direction in the first direction, it bends and extends a second distance in the second direction, and then bends and extends a third distance in the second direction in the first direction. The third distance is greater than the first distance. The first direction and the second direction are opposite, and the first direction is the direction in which the first end of the first plate portion points to the second end.

[0012] This embodiment provides a specific implementation scheme in which the second end of the second plate portion extends to one side of the first plate portion in the second direction. The second end of the second plate portion first extends a first distance in the first direction, then bends and extends a second distance in the second direction, and then extends in the second direction of the first direction, roughly forming a U-shape with uneven heights on the left and right. Because the second direction is opposite to the first direction, the second end of the second plate portion is equivalent to extending in the opposite direction of the first direction after extending in the first direction. When the third distance is greater than the first distance, plus the second distance extended in the second direction, it can be extended to one side of the first plate portion in the second direction. Combined with the above analysis, it can be seen that when the second end of the second plate portion extends to one side of the first plate portion in the second direction, it is beneficial to balance the size of the substrate cut in the first direction and the size of the substrate cut in the second direction, thereby improving the utilization rate of the substrate.

[0013] In a second aspect, an embodiment of the present application provides a battery. The battery includes a battery body and a flexible circuit board provided in any one of the first aspects. The thickness direction of the first plate portion of the flexible circuit board is in the same direction as the thickness direction of the battery body, and the first end of the first plate portion is electrically connected to the battery body. The second plate portion of the flexible circuit board extends to one side of the battery body.

[0014] It can be understood that, except for separate description, the beneficial effects of the battery provided by the embodiment of the second aspect can be found in the relevant description of the flexible circuit board in the first aspect, and will not be repeated here.

[0015] According to the above analysis of the flexible circuit board, the second board portion and the first board portion are not stacked in the thickness direction of the first board portion, and the formed flexible circuit board is a single-layer structure. When the thickness direction of the first board portion of the flexible circuit board is the same as the thickness direction of the battery body (i.e., the thickness direction of the battery), the thickness of the flexible circuit board with a single-layer structure is distributed in the thickness direction of the battery. Compared with the solution in the related art that the thickness of the flexible circuit board with a double-layer structure is distributed in the thickness direction of the battery, the flexible circuit board with a single-layer structure is conducive to reducing the thickness of the battery at the flexible circuit board.

[0016] It should be noted that the second board portion of the flexible circuit board extends to one side of the battery body, so that the flexible circuit board is electrically connected to the main board arranged on one side of the battery body through the first electrical connection portion arranged at the second end of the second board portion.

[0017] In a third aspect, an embodiment of the present application provides an electronic device. The electronic device includes a mainboard and a battery as described in any one of the second aspects. A second electrical connection portion is provided on the board surface of the mainboard. The mainboard is provided on one side of the battery body of the battery, and the second end of the second board portion of the flexible circuit board of the battery extends to the board surface side of the mainboard; the second board portion is electrically connected to the second electrical connection portion through the first electrical connection portion on the second board portion.

[0018] It is understandable that, except for separate descriptions, the beneficial effects of the electronic device provided by the embodiment of the third aspect can be found in the relevant description of the battery in the second aspect, and will not be repeated here. In electronic devices with thin and light requirements, the thickness direction of the battery body is also the thickness direction of the electronic device. In this electronic device, the thickness of the flexible circuit board with a single-layer structure 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 thin and light requirements of the electronic device.

[0019] The second end of the second board portion of the flexible circuit board extends to the board surface side of the main board located on one side of the battery body, opposite to the board surface of the main board, so that the first electrical connection portion of the second end of the second board portion and the second electrical connection portion on the board surface side of the main board can be opposite to each other to achieve electrical connection.

[0020] As a non-limiting embodiment, the electronic device further comprises a pressing plate. The electronic device further comprises a pressing plate. The portion where the second plate portion extends to the plate surface side of the main board is an easy deformation zone. The first electrical connection portion is arranged in the easy deformation zone. The pressing plate is attached to a side of the easy deformation zone that is away from the main board. The pressing plate is fixed to the main board by a fixing member.

[0021] It can be understood that when the easily deformable area is arched away from the mainboard, if the side of the easily deformable area facing away from the mainboard is the screen, the screen may be easily lifted up, resulting in reliability problems such as white spots on the screen; if the side of the easily deformable area facing away from the mainboard is the back cover, the cover may be lifted up, resulting in the appearance problem of bulging in the corresponding area of ​​the back cover.

[0022] Based on this, in this embodiment, by placing a pressure plate on the side of the easily deformable area facing away from the main board, and fixing the pressure plate to the main board using a fixing member, a force toward the easily deformable area can be applied in the thickness direction of the pressure plate. This force causes the pressure plate to fit on the surface of the easily deformable area, flattening the easily deformable area, thereby solving reliability problems or appearance problems such as white spots on the screen caused by the easily deformable area arching away from the main board.

[0023] In a fourth aspect, an embodiment of the present application provides a battery assembly method for assembling a battery in an electronic device. The electronic device has a battery position and a mainboard located on one side of the battery position. The assembly method includes: when the mainboard is assembled to one side of the battery position and the battery is in the current position, obtaining the first position of the flexible circuit board of the battery and the second position of the mainboard; the first position is used to characterize the position of the first electrical connection part of the flexible circuit board; the second position is used to characterize the position of the second electrical connection part of the mainboard; according to the first position and the second position, assembling the battery to the target position of the battery position, the target position is a position that makes the first electrical connection part and the second electrical connection part correspond; electrically connecting the first electrical connection part and the second electrical connection part.

[0024] In the related assembly method, the center alignment algorithm is used for battery assembly, that is, the center line of the battery body is aligned with the center line of the battery position for assembly. The related assembly method uses the position on the battery body and the position of the battery position as the reference position during battery assembly, which will cause the tolerances such as the incoming material tolerance and the assembly tolerance to be accumulated, resulting in the misalignment of the first electrical connection part on the flexible circuit board and the second electrical connection part on the main board.

[0025] It should be noted that, in the case that the first electrical connection part of the battery and the second electrical connection part of the mainboard are misaligned, if the first electrical connection part of the battery and the second electrical connection part of the mainboard are forcibly electrically connected, the flexible circuit board may experience the following two situations: First, it may be arched due to redundancy, thereby causing reliability problems such as white spots on the screen or appearance problems such as bulging in the corresponding area of ​​the back cover; Second, it may be torn or the electrical connection may be loose due to pulling, thereby reducing the reliability of the electrical connection between the battery and the mainboard.

[0026] In this embodiment, when assembling the battery, the first position of the flexible circuit board of the battery is used to characterize the position of the first electrical connection part, and the second position of the main board is used to characterize the position of the second electrical connection part, and these are used as reference positions for assembly. Because the first position is the position on the flexible circuit board where the first electrical connection part is located, and the second position is the position on the main board where the second electrical connection part is located, compared with the solution of characterizing the position of the first electrical connection part by other structures other than the flexible circuit board (such as the center line of the battery body used in the relevant assembly method), and characterizing the position of the second electrical connection part by other structures outside the main board (such as the center line of the battery position used in the relevant assembly method), the dimension chain is interrupted, and 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 will not be introduced, and the position of the first electrical connection part and the position of the second electrical connection part can be more accurately characterized.

[0027] Based on this, compared with the relevant assembly method, using the first position of the flexible circuit board of the battery and the second position of the main board as the reference position when assembling the battery can reduce the influence of the above tolerances (such as the material tolerance of the battery position, the 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 part and the second electrical connection part, thereby improving the misalignment of the first electrical connection part on the flexible circuit board and the second electrical connection part on the main board, so that the first electrical connection part and the second electrical connection part correspond to each other. In the case where the first electrical connection part and the second electrical connection part correspond to each other, electrically connecting the first electrical connection part and the second electrical connection part can improve the arching or pulling phenomenon of the flexible circuit board, thereby solving the reliability problems such as white spots on the screen caused by the arching of the flexible circuit board or the appearance problems of the arching of the corresponding area of ​​the back cover, and also solving the problems of tearing or poor contact caused by pulling the flexible circuit board, thereby improving the reliability of the electrical connection between the battery and the main board.

[0028] As a non-limiting embodiment, the battery assembly method is used to assemble a battery in an electronic device as described in any one of the third aspects. The target position is a position where the first electrical connection portion and the second electrical connection portion correspond to each other in the first direction.

[0029] It should be noted that, for a battery with a flexible circuit board having the aforementioned double-layer structure, since the second board portion of the flexible circuit board is bent in the first direction to the board surface side of the first board portion for stacking, even if the battery is assembled using the aforementioned related assembly method and causes the first electrical connection portion and the second electrical connection portion to be misaligned in the first direction, the position of the first electrical connection portion in the first direction can be adjusted by adjusting the position of the second board portion relative to the first board portion in the first direction, thereby improving the misalignment.

[0030] For the battery in the electronic device described in any one of the third aspects, since the flexible circuit board used is the flexible circuit board with a single-layer structure described in any one of the first aspects, it is impossible to adjust the position of the first electrical connection part in the first direction by adjusting the position of the second board part relative to the first board part in the first direction. Based on this, the assembly of the battery in the electronic device described in any one of the third aspects is suitable for using this assembly method to improve the misalignment of the first electrical connection part and the second electrical connection part in the first direction.

[0031] As a non-limiting embodiment, when the current position is the position corresponding to the battery position in the second direction, the above-mentioned assembling the battery to the target position of the battery position according to the first position and the second position includes: Determine the actual spacing between the first position and the second position in the first direction; obtain the designed spacing between the first position and the second position in the first direction; According to the actual spacing and the design spacing, the battery is assembled to the target position. If the actual spacing is not equal to the design spacing, when the battery is assembled from the current position to the target position of the battery position, the target movement amount is moved along the movement direction in the first direction, wherein the movement direction is determined according to the size relationship between the actual spacing and the design spacing, and the target movement amount is determined according to the absolute value of the difference between the actual spacing and the design spacing; if the actual spacing is equal to the design spacing, when the battery is assembled from the current position to the target position of the battery position, it does not move in the first direction.

[0032] It should be noted that, when the current position is the position corresponding to the battery position in the second direction, whether the actual spacing is the same as the designed spacing can indicate whether the first electrical connection portion and the second electrical connection portion are misaligned in the first direction.

[0033] The actual spacing is not equal to the design spacing, indicating that the first electrical connection part and the second electrical connection part are misaligned in the first direction. Among them, the size relationship between the actual spacing and the design spacing can indicate the misalignment direction of the first electrical connection part and the second electrical connection part in the first direction. The battery moves in the opposite direction of the misalignment direction (i.e., the movement direction), which can weaken the misalignment of the first electrical connection part and the second electrical connection part in the first direction, and promote the first electrical connection part and the second electrical connection part to correspond to each other in the first direction. The absolute value of the difference between the actual spacing and the design spacing can indicate the size of the misalignment amount of the first electrical connection part and the second electrical connection part in the first direction. The misalignment amount is equal to the required movement amount of the battery in the first direction when the first electrical connection part and the second electrical connection part are not misaligned in the first direction. Based on this, in this embodiment, the target movement amount is determined according to the absolute value of the difference between the actual spacing and the design spacing, which is equivalent to being determined according to the required movement amount, which helps to promote the first electrical connection part and the second electrical connection part to correspond to each other in the first direction. Based on this, when the battery is assembled from the current position to the target position of the battery position, moving the above-mentioned target movement amount along the above-mentioned movement direction in the first direction helps to assemble the battery to the target position where the first electrical connection part and the second electrical connection part correspond to each other in the first direction.

[0034] The actual spacing is equal to the designed spacing, indicating that the first electrical connection portion and the second electrical connection portion are not misaligned in the first direction. Based on this, in this case, during the process of assembling the battery to the target position, the embodiment keeps the battery from moving in the first direction, thereby maintaining the first electrical connection portion and the second electrical connection portion not misaligned in the first direction, and assembling the battery to the target position where the first electrical connection portion and the second electrical connection portion correspond to each other in the first direction.

[0035] It can be understood that when the first electrical connection portion and the second electrical connection portion correspond to each other in the first direction, the aforementioned pulling or arching phenomenon is less likely to occur when the first electrical connection portion and the second electrical connection portion are electrically connected.

[0036] 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 in the first direction toward the first misalignment direction relative to the second electrical connection portion, that is, the misalignment direction of the first electrical connection portion and the second electrical connection portion in the first direction is the first misalignment direction, and the first misalignment direction is one of the first direction and the second direction in the first direction. The first electrical connection portion needs to be moved to a first movement direction opposite to the first misalignment direction, that is, the movement direction is the first movement direction, and the first movement direction is the other of the first direction and the second direction in the first direction.

[0037] The target movement amount is the smaller value between the first movable amount and the required movement amount. The first movable amount is the movement amount that the battery position can provide to the battery in the first moving direction. The required movement amount is the absolute value of the difference between the actual spacing and the designed spacing. The target movement amount is the smaller value between the first movable amount and the required movement amount, which is divided into the following three cases: First, when the required movement amount is greater than the first movable amount (the smaller value is the first movable amount), it indicates that the first movable amount is insufficient to provide the required movement amount, and the battery can only move along the first movable amount at most, that is, the target movement amount is the first movable amount.

[0038] Second, when the required movement amount is less than the first movable amount (the smaller value is the required movement amount), it indicates that the first movable amount is sufficient to provide the required movement amount, and the battery can move the required movement amount, that is, the target movement amount is the required movement amount, that is, the absolute value of the difference between the actual spacing and the designed spacing.

[0039] Third, when the required movement amount is equal to the first movable amount (the smaller value is the required movement amount or the first movable amount), it indicates that the first movable amount just provides the required movement amount, and the battery can move the required movement amount, that is, the target movement amount is the required movement amount or the first movable amount, that is, the absolute value of the difference between the actual spacing and the designed spacing.

[0040] In this embodiment, the target movement amount is the smaller value between the required movement amount and the first movable amount, so that the battery will not be moved out of the battery position and cannot be assembled.

[0041] When the actual spacing is smaller than the designed spacing, the first direction is offset toward the first misalignment direction, that is, the misalignment direction of the first electrical connection part and the second electrical connection part in the first direction is the second misalignment direction, and the second misalignment direction is the other of the first direction and the second direction in the first direction. The first electrical connection part needs to be moved to a second moving direction opposite to the second misalignment direction, that is, the moving direction is the second moving direction, and the second moving direction is one of the first direction and the second direction in the first direction. The target movement amount is the smaller value of the second movable amount and the required movement amount, and the second movable amount is the movement amount that the battery position can provide to the battery in the second moving direction. The target movement amount is the smaller value of the second movable amount and the required movement amount, and the description of the three cases where the momentum is the smaller value of the first movable amount and the required movement amount can be adaptively referred to.

[0042] As a non-limiting embodiment, when the center line of the battery position in the first direction and the center line of the battery body in the first direction are in the same straight line, the first movable amount and the second movable amount are (AB) / 2. Where A is the accommodation size of the battery position in the first direction, and B is the size of the battery body in the first direction.

[0043] Normally, electronic devices are designed to meet the following conditions: when the first electrical connection portion and the second electrical connection portion are not misaligned in the first direction, the center line of the battery position in the first direction and the center line of the battery body in the first direction are in the same straight line. In this way, the battery can be assembled to the battery position in a relatively centered position, so that the weight of the electronic device is more balanced in the first direction. When the center line of the battery position in the first direction and the center line of the battery body in the first direction are in the same straight line, the single-sided gap between the battery position and the battery body is (AB) / 2. Based on this, the amount of movement that the battery position can provide to the battery body in the first orientation and the second orientation in the first direction is (AB) / 2, that is, the first movable amount and the second movable amount are (AB) / 2. For example, (AB) / 2 is greater than 0.1cm.

[0044] As a non-limiting embodiment, the first position is an edge of a side of the second plate portion facing away from the first plate portion in the first direction.

[0045] It should be noted that the first end of the second plate portion is called a fixed end because it fixes the second end of the first plate portion, and the first electrical connection portion of the second end of the second plate portion is a free end before being electrically connected to the second electrical connection portion. Since the second plate portion is a flexible structure, the closer the position of the second plate portion is to the free end in the first direction, the easier it is to change, and the less suitable it is to be used as the first position.

[0046] Since the second end of the second plate portion extends to one side of the first plate portion in the second direction, the first plate portion can represent the position of the second end (i.e., the free end) of the second plate portion in the first direction. Based on this, this embodiment selects the first position as the side edge of the second plate portion facing away from the first plate portion in the first direction, which is equivalent to selecting the position of the second plate portion farthest from the free end in the first direction as the first position. This position is less likely to change than other positions of the second plate portion, and has little effect on the misalignment of the first electrical connection portion and the second electrical connection portion in the first direction. In addition, selecting the side edge of the second plate portion facing away from the first plate portion in the first direction as the first position helps to obtain the actual spacing between the first position and the second position in the first direction during the assembly process of the battery, thereby helping to cause the first electrical connection portion and the second electrical connection portion to correspond to each other in the first direction.

[0047] As a non-limiting embodiment, the second position is a side edge of the copper leakage area of ​​the mainboard in the first direction.

[0048] It should be noted that, because the copper leakage area of ​​the mainboard has a significant color difference compared to other positions of the mainboard (the mainboard is usually green), it is easy to distinguish during the image recognition process. Based on this, in this embodiment, the edge of the copper leakage area of ​​the mainboard is used as the second position, which is easy to be identified during the image recognition process, thereby facilitating the rapid and accurate capture of the second position. In addition, the selection of one side edge of the copper leakage area in the first direction helps to obtain the actual spacing between the first position and the second position in the first direction during the assembly process of the battery, thereby helping to cause the first electrical connection portion and the second electrical connection portion to correspond to each other in the first direction.

[0049] In the fifth aspect, the embodiment of the present application also provides another battery assembly method for realizing the assembly of the battery in the electronic device provided in the third aspect, wherein the electronic device has a battery position. The assembly method comprises: moving the battery to the battery position of the electronic device, and extending the flexible circuit board of the battery to the board surface side of the main board to electrically connect the main board through the flexible circuit board, and the area where the flexible circuit board extends to the board surface side of the main board is the easily deformed area; placing the pressing plate on the side of the easily deformed area facing away from the main board; using the cover plate to push the pressing plate to the side where the easily deformed area is located, so that the easily deformed area is flattened on the surface of the main board; a pressing head is provided on the side of the cover plate facing the pressing plate, and the pressing head contacts the pressing plate before the cover plate, and the position where the pressing head contacts the pressing plate is located between two fixed positions, and the fixed positions are used to set fixings; when the cover plate pushes the pressing plate to flatten the easily deformed area, a fixing is provided at each of the two fixed positions to fix the pressing plate to the main board.

[0050] In the related art, the cover plate is not provided with a pressure head. When two fixing parts are used to fix the easily deformed area, the easily deformed area between the two fixing positions is prone to arch back toward the mainboard, thereby causing reliability problems such as white spots on the screen or appearance problems such as bulging in the corresponding area of ​​the back cover.

[0051] In this assembly method, the pressure head contacts and presses down the pressure plate before the cover plate. Based on this, when two fixing members are used to fix the easily deformable area, the position of the easily deformable area between the two fixing positions is supported by the pressure head and is not easy to bend, thereby solving reliability problems or appearance problems such as white spots on the screen caused by the easily deformable area being bent away from the mainboard.

[0052] As a non-limiting example, the Rockwell hardness of the indenter is 50 to 60 HR. In this case, the indenter is in soft contact with the pressure plate and is not likely to cause damage to the pressure plate during the pressing process. In addition, the indenter with a Rockwell hardness of 50 to 60 HR is a soft material that is easily deformed during the pressing process so that the cover plate can contact the pressure plate, thereby pushing the pressure plate to flatten the easily deformed area on the main board surface.

[0060] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0061] The embodiment of the present application provides an electronic device. Exemplarily, the electronic device may be a mobile phone, a tablet computer, a desktop, a laptop, a handheld computer, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a cellular phone, a personal digital assistant (PDA), an augmented reality (AR) or virtual reality (VR) device, etc., which includes a battery. The embodiment of the present application does not impose any special restrictions on the specific form of the electronic device. The following description takes the electronic device as a tablet computer as an example.

[0062] For example, see Figure 1 and Figure 2 , Figure 1 A schematic diagram of the structure of an electronic device 000 provided in an embodiment of the present application is shown in FIG. Figure 2 for Figure 1 The schematic diagram of the structural decomposition of the electronic device 000 is shown.

[0063] In this embodiment, the electronic device 000 is a tablet computer, including a screen 001, a back cover 002, Figure 2 The displayed middle board 003, camera module 004, battery 005 and main board 006. It is understandable that Figure 1 and Figure 2 Only some components of the electronic device 000 are schematically shown, and the actual shapes, sizes, positions and structures of these components are not subject to the present invention. Figure 1 and Figure 2 Furthermore, in other embodiments of the present application, the electronic device 000 may include more or fewer components than those shown in the figure, or combine some components, or separate some components, or arrange the components differently.

[0064] These components are introduced below.

[0065] Screen 001 is used to display images, videos, etc. Screen 001 can be a flexible display screen or a rigid display screen. For example, the display screen can be an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode or an active-matrix organic light-emitting diode (AMOLED) display screen, a mini organic light-emitting diode (MIL-I) display screen, a micro organic light-emitting diode (MIL-I) display screen, a micro organic light-emitting diode (MIL-I) display screen, a quantum dot light-emitting diode (QLED) display screen, or a liquid crystal display (LCD).

[0066] For the convenience of the following description, an XYZ coordinate system is established, defining the length direction of the electronic device 000 as the X-axis direction, the width direction of the electronic device 000 as the Y-axis direction, and the thickness direction of the electronic device 000 as the Z-axis direction. It should be noted that the coordinate system setting of the electronic device 000 can be flexibly set according to actual needs.

[0067] The back cover 002 , also called the battery cover, is used to protect the internal electronic components of the electronic device 000 . The back cover 002 includes a back plate 021 and a frame 022 .

[0068] The back plate 021 is located on one side of the back side of the screen 001 and is stacked with the screen 001 in the Z-axis direction.

[0069] The frame 022 surrounds the side of the screen 001 and the back plate 021, and is fixedly connected to the screen 001 and the back plate 021. For example, the frame 022 can be fixedly connected to the screen 001 by adhesive. For example, the frame 022 and the back plate 021 are an integrally formed structure. In some other embodiments, the frame 022 can also be an integrally formed structure with the middle plate 003.

[0070] It can be understood that the screen 001, the back panel 021, and the frame 022 together enclose a storage space for the electronic device 000, so that functional components of the electronic device 000 can be placed in the storage space, such as Figure 2 The functional components shown, such as the camera module 004, the battery 005, and the mainboard 006, simultaneously seal and protect the functional components located in the accommodating space.

[0071] The middle plate 003 is used to install 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 is used as the structural "skeleton" of the electronic device 000, and is used to install the functional components of the electronic device 000, such as the camera module 004, the battery 005, the main board 006, etc.

[0072] The camera module 004 is used to take photos / videos. The number of camera modules 004 can be one or more. Only one front camera is shown in the figure. The camera module 004 is fixed to the surface of the middle plate 003 facing the screen 001, and is specifically fixed to a position near the center of the long side of the middle plate 003 (the center of the edge extending along the X-axis direction). The "nearby position" means that the distance between this position and the center of the long side of the middle plate 003 is small, and the distance can be set as needed. Of course, in some other embodiments, the camera module 004 can be fixed to other positions of the middle plate 003, for example, the camera module 004 is fixed to the surface of the middle plate 003 facing the back plate 021; for another example, the camera module 004 is 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, clamping, welding, etc., and the light incident surface of the camera module 004 faces the screen 001. A light-transmitting area 011 is provided at a position of the screen 001 directly opposite to the camera module 004 , so that light can enter the camera module 004 through the light-transmitting area 011 , thereby realizing the shooting function.

[0073] The battery 005 is used to supply power to the functional components of the electronic device 000 that require power. Figure 2 In the figure, a battery position 031 is provided on the middle plate 003 in order to install the battery 005. The battery position 031 may be a hole on the middle plate 003, which is arranged at intervals on the side of the camera module 004 in the negative direction of the Y axis, so as to facilitate the installation of the main board 006 between the battery 005 and the camera module 004. The battery 005 is installed in the battery position 031, and is stacked with the screen 001 and the back plate 021 in the Z axis direction. In order to show the battery position 031, the battery 005 and the middle plate 003 are decomposed along the Z axis direction in the figure.

[0074] Of course, in some other embodiments, the battery position 031 can also be set at other positions of the middle plate 003, so that the battery 005 is installed at other positions of the middle plate 003. For example, in the Y-axis direction, the battery position 031 can be set between the main board 006 and the camera module 004, so that the battery 005 is located between the main board 006 and the camera module 004.

[0075] The mainboard 006 is an important carrier of functional components, and is used to electrically connect functional components that are integrated and / or not integrated on the mainboard 006. For example, the mainboard 006 can be electrically connected to a power management module (not shown) integrated on the mainboard 006 and a battery 005 that is not integrated on the mainboard 006, respectively, so as to electrically connect the power management module and the battery 005. In this way, the battery 005 can transmit electric energy to the power management module via the mainboard 006, so as to supply power to the functional components of the electronic device 000 that need power via the power management module.

[0076] Figure 2 In the figure, in order to install the main board 006, a main board position 032 is provided on the middle plate 003. The main board position 032 can be a hole on the middle plate 003, which is provided on one side of the battery 005 in the Y-axis direction, specifically on the side in the positive direction of the Y-axis. The middle plate 003 and the main board 006 are not decomposed in the Z-axis direction in the figure, so the position of the main board position 032 can be roughly referred to the position of the main board 006. The main board 006 is provided at the main board position 032 on the middle plate 003, and is generally (except for individual structures) located on the side of the battery 005 close to the camera module 004 in the Y-axis direction, and is stacked with the screen 001 and the back plate 021 in the Z-axis direction. Of course, in some other embodiments, the main board 006 can also be fixed at other positions of the middle plate 003, such as the main board 006 is generally located on one side of the battery 005 in the X-axis direction.

[0077] It should be noted that, as the demand for thinner and lighter electronic devices 000 increases, controlling the thickness of electronic devices 000 has become a key research and development direction in the industry. If the thickness of electronic devices 000 is too large, the electronic devices 000 will not meet the demand for thinner and lighter devices. Figure 2 In the embodiment, different parts of the battery 005 occupy different thickness spaces of the electronic device 000, which are specifically determined by the size of each part in the Z-axis direction. In order to meet the requirements of thinning and lightening the electronic device 000, it is necessary to control the size of each part of the battery 005 in the Z-axis direction.

[0078] In the related art, the size of the flexible circuit board of the battery 005 in the Z-axis direction is relatively large, so that the thickness of the battery 005 at the flexible circuit board makes the electronic device 000 fail to meet the requirements of lightness and thinness. Figure 2 The thickness of the battery 005 at the flexible circuit board is reduced by reducing the thickness of the flexible circuit board it contains, thereby reducing the thickness of the electronic device 000 to meet the requirements of the electronic device 000 to be thin and light. Figure 3 The battery 005 provided in the embodiment of the present application is described.

[0079] For example, please refer to Figure 3 , Figure 3 for Figure 2 The battery 005 includes a battery body 100 and a flexible circuit board 200.

[0080] The battery body 100 can be understood as the battery 005 placed Figure 2 The battery part of the battery position 031 shown (excluding the flexible circuit board 200). The battery body 100 includes but is not limited to the battery cell group 110. For example, Figure 3 In the embodiment, the battery body 100 may further include a protection circuit board 120 and the like.

[0081] The battery cell group 110 is the core part of the battery 005 and is responsible for the storage and release of electric energy. It is usually composed of a positive electrode, a negative electrode, an electrolyte, and a separator, and can generate electric current through chemical reactions. In order to increase the power of the battery 005, in some embodiments, the battery cell group 110 can be formed by combining multiple battery cells 111. For example, Figure 3 In the embodiment, the battery cell group 110 includes two battery cells 111 arranged side by side in the X-axis direction. Of course, in other embodiments, the battery cells 111 may also be arranged side by side in other directions, which is not limited in the embodiment of the present application.

[0082] The battery cell group 110 is roughly a plate-like structure in appearance. The so-called plate-like structure refers to a structure whose length and width are much greater than its thickness. For a plate-like structure, the surface with length and width is the plate surface of the plate-like structure, and the thickness direction of the plate-like structure is perpendicular to the plate surface of the plate-like structure. The length direction of the battery cell group 110 shown in the figure is the X-axis direction, the width direction is the Y-axis direction, and the thickness direction is the Z-axis direction. In the embodiment of the present application, the two side surfaces of the battery cell group 110 that are disposed back to back in the X-axis direction are respectively referred to as the left side and right side surfaces of the battery cell group 110, the two side surfaces of the battery cell group 110 that are disposed back to back in the Y-axis direction are respectively referred to as the upper side and lower side surfaces of the battery cell group 110, and the two plate surfaces of the battery cell group 110 that are disposed back to back in the Z-axis direction are respectively referred to as the upper plate surface and the lower plate surface of the battery cell group 110. Similar terms related to "plate" in the embodiment of the present application can be understood with reference to the explanations here. It should be noted that the thickness direction of the battery 005 is determined by the thickness direction of the battery body 100. In this embodiment, the thickness direction of the battery body 100 is the Z-axis direction, so the thickness direction of the battery 005 is also the Z-axis direction.

[0083] The protection circuit board 120 is an important component of the battery 005 and is electrically connected to the battery pack 110. It monitors the voltage and charge and discharge current of the battery pack 110 through electronic circuits, and controls the on and off of the current loop under abnormal conditions to protect the battery pack 110 from damage. The main functions may include overcharge protection, over-discharge protection, overcurrent protection, short circuit protection, and temperature protection to prevent the battery 005 from being damaged or causing safety accidents due to extreme conditions. The protection circuit board 120 usually includes components such as control IC, MOS switch, resistor, capacitor, as well as NTC temperature sensor and ID memory, which are used to monitor the status of the battery 005 and control protection actions.

[0084] Figure 3 In the figure, the protection circuit board 120 covers the lower plate surface of the battery group 110 (the side facing away from the upper plate surface of the battery group 110 shown in the figure), the left side surface and the right side surface of the battery group 110, and the protection circuit board 120 also extends to the side to which the upper side surface of the battery group 110 faces, that is, extends to the side of the battery group 110 in the positive direction of the Y axis. In the embodiment of the present application, the part of the protection circuit board 120 extending to the side of the battery group 110 in the Y axis direction is called the extension part 121. The thickness direction of the extension part 121 is also in the Z axis direction.

[0085] The flexible circuit board 200 is a circuit board with bendable characteristics, which is used for the electrical connection of the battery 005. Figure 2 Specifically, the flexible circuit board 200 extends from one side of the extension part 121 in the positive direction of the Z axis to one side of the extension part 121 in the positive direction of the Y axis, so as to facilitate the connection with the main board 006. Figure 2 The main board 006 located on one side of the battery position 031 in the positive direction of the Y axis is electrically connected, thereby realizing electrical connection between the battery 005 and the main board 006.

[0086] When the battery 005 is electrically connected to the main board 006, on the one hand, the battery 005 can release the electric energy stored in the battery cell group 110 to the main board 006 through the flexible circuit board 200, and the main board 006 can also store electric energy in the battery cell group 110 of the battery 005 through the flexible circuit board 200. On the other hand, the battery 005 can transmit the signal of the status of the battery 005 monitored by the protection circuit board 120 to the main board 006 through the flexible circuit board 200, and the main board 006 can also transmit the control signal to the protection circuit board 120 of the battery 005 through the flexible circuit board 200.

[0087] Figure 3In the figure, 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 the dimension of the flexible circuit board 200 in the Z-axis direction, which affects the thickness of the battery 005 at the flexible circuit board 200. It can be seen that by reducing the thickness of the flexible circuit board 200, the thickness of the battery 005 at the flexible circuit board 200 can be reduced, thereby reducing the thickness space occupied by the battery 005 at the flexible circuit board 200 in the thickness of the electronic device 000, and meeting the requirements for thinness of the electronic device 000.

[0088] In the related art, the flexible circuit board 200 is a double-layer structure, which results in a relatively large thickness of the flexible circuit board 200, and the thickness of the battery 005 at the flexible circuit board 200, so that the electronic device 000 does not meet the requirements of being lightweight. Figure 3 The flexible circuit board 200 in the embodiment adopts a single-layer structure to reduce the thickness of the flexible circuit board 200, thereby reducing the thickness of the battery 005 at the flexible circuit board 200, thereby meeting the requirements of the electronic device 000 for being thin and light. Figures 4 to 5 Conduct comparative analysis.

[0089] For example, please refer to Figure 4 , Figure 4 A schematic diagram of the structure of a flexible circuit board 200 provided in an embodiment of the present application. The flexible circuit board 200 can be applied to Figure 3 The battery 005 shown. The battery 005 with the flexible circuit board 200 can be applied to a front-mounted structure (the battery is installed on the side of the middle plate facing the back cover), a flip-mounted structure (the battery is installed on the side of the middle plate facing the screen), a high-power battery (the battery power is increased by increasing or decreasing the size of the battery in the X-axis direction and the Y-axis direction without increasing the thickness), and an electronic device 000 with a thinner thickness requirement.

[0090] The flexible circuit board 200 is used to electrically connect the first device and the second device, thereby realizing signal transmission between the first device and the second device. Figure 3 In the case of the battery 005 shown, the first device may be Figure 3 In the battery body 100, the second device may be Figure 2 Of course, in some other embodiments, the flexible circuit board 200 can also be used in other scenarios to achieve electrical connection between the first device and the second device in the other scenarios. Figure 3 The battery 005 shown is used as an example for explanation.

[0091] The flexible circuit board 200 includes a first board portion 210 and a second board portion 220 .

[0092] The flexible circuit board 200 is a circuit board with bendable characteristics. It should be noted that the bendable characteristics do not require the flexible circuit board 200 to be a flexible structure throughout. In the specific implementation process, at least part of the flexible circuit board 200 is a flexible structure, which can make the flexible circuit board 200 have the bendable characteristics.

[0093] for example, Figure 4 In the embodiment, the first plate portion 210 is a rigid structure, and the second plate portion 220 is a flexible structure, so that the flexible circuit board 200 has a bendable property. In this case, the flexible circuit board 200 can be cut from a panel formed by splicing a rigid substrate and a flexible substrate. Of course, in some other embodiments, the entire flexible circuit board 200 is a flexible structure, which is not limited in the embodiment of the present application.

[0094] The first plate portion 210 and the second plate portion 220 are described below respectively.

[0095] First, the first plate portion 210 will be described.

[0096] The first plate portion 210 includes a first end 210a and a second end 210b that are arranged in a first direction (such as the X-axis direction shown in the figure). The first direction shown in the figure is the X-axis direction, which is perpendicular to the thickness direction of the first plate portion 210 (such as the Z-axis direction shown in the figure). Unless otherwise specified, the subsequent embodiments are described with the X-axis direction replacing the first direction and the Z-axis direction replacing the thickness direction of the first plate portion 210. The first plate portion 210 is a structure for the flexible circuit board 200 to electrically connect the first device, and the first device is Figure 3 The battery body 100 in.

[0097] Next, the second plate portion 220 will be described.

[0098] 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, the second plate portion 220 is easy to move relative to the first plate portion 210, so that the thickness direction of the second plate portion 220 is not necessarily in the Z-axis direction, but approximately in the Z-axis direction.

[0099] The second plate portion 220 includes a first end 220 a and a second end 220 b .

[0100] The first end 220 a of the second plate portion 220 fixes the second end 210 b of the first plate portion 210 (specifically, may fix an end surface of the second end 210 b of the first plate portion 210 in the X-axis direction).

[0101] The second end 220b of the second board portion 220 is provided with a first electrical connection portion (such as a BTB connector male socket 230 shown in the figure) for connecting Figure 2 Motherboard 006 in. Figure 42 shows the BTB connector male socket 230 from the rear view of the second end 220b of the second board portion 220. Figure 2 The main board 006 has a second electrical connection portion (such as a BTB connector socket 061) electrically connected to the first electrical connection portion. The second end 220 b of the second plate portion 220 extends from the first end 220 a of the second plate portion 220 to one side of the first plate portion 210 in a second direction, and the second direction is perpendicular to the first direction and the thickness direction of the first plate portion 210 . Figure 4 In the case where the first direction is the X-axis direction and the thickness direction of the first plate portion 210 is the Z-axis direction, the second direction is the Y-axis direction shown in the figure. Unless otherwise specified, the subsequent embodiments are described with the Y-axis direction instead of the second direction. It should be noted that one side of the first plate portion 210 in the Y-axis direction is the area directly facing the side surface of the first plate portion 210 in the Y-axis direction (the area between the dotted line W1 and the dotted line W2 shown in the figure), that is, the area corresponding to the projection path of the positive projection of the side surface along the Y-axis direction. Figure 4 In the embodiment, the second end 220b of the second plate portion 220 specifically extends to one side of the first plate portion 210 in the positive direction of the Y axis.

[0102] In the Z-axis direction, the second plate portion 220 and the first plate portion 210 do not overlap. In other words, the orthographic projections of the second plate portion 220 and the first plate portion 210 in the Z-axis direction do not overlap. In this case, the second plate portion 220 and the first plate portion 210 are not stacked in the Z-axis direction, and the formed flexible circuit board 200 is a single-layer structure in the Z-axis direction. However, in the related art, the flexible circuit board 200 is a double-layer structure in the Z-axis direction.

[0103] Please refer to Figure 5 , Figure 5 A structural schematic diagram of a flexible circuit board 200 provided in the related art. Figure 5 In the flexible circuit board 200 shown, before the second board 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 board portion 210 and the first end 220a and the second end 220b of the second board portion 220 are all arranged back to back in the X-axis direction.

[0104] Since the second board portion 220 is a flexible structure with bendable properties, the second board portion 220 can be bent 180° in the X-axis direction to the board surface side of the first board portion 210 (i.e., one side of the first board portion 210 in the Z-axis direction) for stacking (the bent state is indicated by a solid line in the figure), so that the flexible circuit board 200 has a double-layer structure in the Z-axis direction.

[0105] Before the second plate portion 220 is bent, the second end 220b of the second plate portion 220 extends away from the first plate portion 210 in the X-axis direction in which the first plate portion 210 extends. The first plate portion 210 and the second plate portion 220 are arranged in sequence in the X-axis direction, and the flexible circuit board 200 occupies a large space in the X-axis direction. Based on this, 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 causes the flexible circuit board 200 to have a double-layer structure, which makes the thickness of the flexible circuit board 200 large.

[0106] It can be seen that compared with Figure 5 As for the double-layer structure flexible circuit board 200 shown in FIG. Figure 4 The thickness of the flexible circuit board 200 with a single-layer structure is reduced. According to statistics, this allows the flexible circuit board 200 to have a thickness gain of 0.25 mm.

[0107] In the Figure 4 The single-layer flexible circuit board 200 shown is applied to Figure 3 The battery 005 shown is assembled to Figure 2 When using the electronic device 000 shown in FIG. Figure 6 , Figure 6 for Figure 2 The diagram is a plan view of a middle board 003 and some functional components installed thereon in the electronic device 000 shown. Figure 6 Among them, some functional components installed on the middle plate 003 include camera module 004, battery 005 and main board 006 and so on.

[0108] In order to electrically connect the battery body 100, the first plate portion 210 extends to one side of the battery cell group 110 in the positive direction of the Y axis, and is arranged in the Z axis direction with the extension portion 121 on the same side of the battery cell group 110 in the positive direction of the Y axis, and the first plate portion 210 and the extension portion 121 face each other. The first plate portion 210 and the extension portion 121 are electrically connected to each other, so that the flexible circuit board 200 is electrically connected to the battery body 100. Exemplarily, the way of electrically connecting the flexible circuit board 200 and the extension portion 121 includes but is not limited to one of welding and plugging.

[0109] It should be noted that Figure 6 In the embodiment, the first plate portion 210 is located on one side of the cell group 110 in the positive direction of the Y axis, which is beneficial to reducing the thickness of the battery 005 at the cell group 110 compared to the solution of being located on the plate surface side of the cell group 110. Of course, in some other embodiments, the first plate portion 210 may also be disposed on the plate surface side of the cell group 110, which is not limited in the embodiment of the present application.

[0110] In order to electrically connect the main board 006, the second end 220b of the second board portion 220 extends to one side of the battery body 100 in the positive direction of the Y axis, opposite to the board surface of the main board 006 on the same side in the positive direction of the Y axis of the battery body 100, and the second end 220b of the second board portion 220 is engaged with the BTB connector female socket 061 on the board surface side of the main board 006 through the BTB connector male socket 230 provided thereon to achieve electrical connection, thereby achieving electrical connection between the flexible circuit board 200 and the main board 006.

[0111] Figure 6 In the embodiment, the thickness direction of the first plate portion 210 and the battery body 100 (determined by the thickness direction of the battery cell group 110) is the Z-axis direction. In this case, the thickness of the flexible circuit board 200 affects the thickness of the battery 005 at the flexible circuit board 200. As the thickness of the flexible circuit board 200 decreases, the thickness of the battery 005 at the flexible circuit board 200 decreases. When the thickness of the battery 005 at the flexible circuit board 200 decreases, the contact between the battery 005 and the flexible circuit board 200 can be reduced. Figure 2 The thickness of the electronic device 000 shown in the figure is reduced, thereby meeting the thinness requirement of the electronic device 000. In addition, since the second board portion 220 of the flexible circuit board 200 extends to one side of the first board portion 210 in the Y-axis direction, the thickness of the electronic device 000 can be reduced. Figure 2 The electronic device 000 shown occupies a space in the X-axis direction.

[0112] In addition, compared to Figure 5 As for the flexible circuit board 200 shown in FIG. Figure 4 The flexible circuit board 200 shown has a higher utilization rate of the panel.

[0113] Specifically, please refer to Figure 7 , Figure 7 for Figure 4 The flexible circuit board 200 and Figure 5 The diagram shows the corresponding cutting positions of the flexible circuit board 200 on the panel.

[0114] in, Figure 7 (a) is indicated by a dotted line. Figure 5 The corresponding cutting position of the flexible circuit board 200 shown on the panel, Figure 7 The dashed line in (b) indicates Figure 4 The flexible circuit board 200 is shown at the corresponding cutting position on the panel.

[0115] because Figure 5 The first board portion 210 and the second board portion 220 of the flexible circuit board 200 are arranged in sequence in the X-axis direction, and the flexible circuit board 200 occupies a large space in the X-axis direction. Figure 7In (a), cut from the corresponding cutting position on the puzzle board Figure 5 When the flexible circuit board 200 is cut, the size of the panels cut in the X-axis direction is larger and the size of the panels cut in the Y-axis direction is smaller, resulting in a lower utilization rate of the panels, which is obviously contrary to the need to control costs.

[0116] and Figure 4 In the flexible circuit board 200 shown, the first end 220a of the second board portion 220 is fixed to the second end 210b of the first board portion 210, and the second end 220b of the second board portion 220 extends from the first end 220a of the second board portion 220 to one side of the first board portion 210 in the Y-axis direction. Figure 4 In the embodiment shown, the second plate portion 220 does not continue to extend from the second end 210b of the first plate portion 210 along the X-axis direction and is arranged with the first plate portion 210 in the X-axis direction, but extends to one side of the first plate portion 210 in the Y-axis direction, so as not to occupy a large space in the X-axis direction. Based on this, Figure 7 In (b), cut from the corresponding cutting position on the puzzle board Figure 4 In the flexible circuit board 200 shown, the size of the panels cut in the X-axis direction and the size of the panels cut in the Y-axis direction are more balanced, thereby improving the utilization rate of the panels. According to statistics, this makes the flexible circuit board 200 have a cost benefit of 1.5 RMB.

[0117] As a non-limiting example, please continue to refer to Figure 4 The first plate portion 210 is configured as a long strip. In this case, the X-axis direction may be the length direction of the first plate portion 210 , and the Y-axis direction may be the width direction of the first plate portion 210 .

[0118] It should be noted that, when the first plate portion 210 is configured as a long strip and the X-axis direction is the length direction of the first plate portion 210, Figure 5 The flexible circuit board 200 shown in the figure shows a more obvious situation of low utilization rate of the panels. The above-mentioned design scheme of extending the second end 220b of the second board portion 220 from the first end 220a of the second board portion 220 to one side of the first board portion 210 in the Y-axis direction can further improve the utilization rate of the panels, and the improvement effect on the low utilization rate of the panels is more significant.

[0119] In addition, combined Figure 6, the length direction of the first plate portion 210 is the same as the length direction of the battery body 100, and the length direction of the battery body 100 is reasonably used for the extension of the long strip-shaped first plate portion 210, which can improve the internal space utilization rate of the battery 005 for the electronic device 000. Of course, in some other embodiments, the length direction of the first plate portion 210 can also be the same as the width direction of the battery body 100. In this case, the second plate portion 220 extends to one side of the battery body 100 in the X-axis direction, and the main board 006 is located on one side of the battery body 100 in the X-axis direction, so as to facilitate the second plate portion 220 to be electrically connected to the main board 006.

[0120] As a non-limiting example, please continue to refer to Figure 4 In order to realize that 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, the second end 220b of the second plate portion 220 extends the first distance D1 along the first direction (as shown in the positive direction of the X-axis) to obtain the first sub-plate portion, then bends and extends the second distance D2 in the Y-axis direction to obtain the second sub-plate portion, and then bends and extends the third distance D3 in the second direction of the first direction (as shown in the negative direction of the X-axis) to obtain the third sub-plate portion. The second plate portion 220 is roughly U-shaped with uneven heights on the left and right. The third distance D3 is greater than the first distance D1. Among them, the first direction and the second direction are opposite, and the first direction is the direction from the first end of the first plate portion 210 to the second end.

[0121] Figure 4 In the embodiment, the direction in which the first end 210a of the first plate portion 210 points to the second end 210b is the positive direction of the X-axis, that is, the first direction of the first direction is the positive direction of the X-axis. It can be understood that in some other embodiments, the first direction of the first direction is the positive direction of the X-axis, and the second direction of the first direction is the negative direction of the X-axis. The subsequent embodiments are described by taking the first direction of the first direction as the positive direction of the X-axis and the second direction of the first direction as the negative direction of the X-axis as an example.

[0122] In this embodiment, since the positive direction of the X-axis is opposite to the negative direction of the X-axis, the second end 220b of the second plate portion 220 is equivalent to extending in the positive direction of the X-axis and then turning back to extend in the negative direction of the X-axis. When the third distance D3 is greater than the first distance D1, plus the second distance D2 extending in the Y-axis direction, it can be extended to one side of the first plate portion 210 in the Y-axis direction. Combined with the above analysis, it can be seen that when the second end 220b of the second plate portion 220 extends to one side of the first plate portion 210 in the Y-axis direction, it is beneficial to balance the size of the panels cut in the X-axis direction and the size of the panels cut in the Y-axis direction, thereby improving the utilization rate of the panels.

[0123] 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 Figure 4 For example, Figure 8 Two optional embodiments are provided.

[0124] For example, please refer to Figure 8 , Figure 8 Schematic diagrams of planar structures of other flexible circuit boards 200 provided in embodiments of the present application.

[0125] 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 fixes the side surface of the second end 210b of the first plate portion 210 in the Y-axis direction), and the second end 220b of the second plate portion 220 is bent and extended a certain distance along the Y-axis direction from the first end 220a of the second plate portion 220, and then bent and extended a certain distance in the negative direction of the X-axis. The second plate portion 220 is generally L-shaped.

[0126] Figure 8 In (b), the first end 220a of the second plate portion 220 fixes the second end 210b of the first plate portion 210 (specifically fixes the side surface of the second end 210b of the first plate portion 210 in the Y-axis direction), and the second end 220b of the second plate portion 220 gradually extends from the first end 220a of the second plate portion 220 in the negative direction of the X-axis.

[0127] Figure 8 The two embodiments provided are merely for illustration. In a specific implementation, the second end 220b of the second plate portion 220 may also have more extension modes, as long as it extends to one side of the first plate portion 210 in the Y-axis direction.

[0128] Below Figure 2 The assembly method of the battery 005 in the electronic device 000 is illustrated as an example.

[0129] For example, please refer to Fig. 9 , Fig. 9 A structural assembly schematic diagram provided for related assembly methods.

[0130] The related assembly method uses a center alignment algorithm to assemble the battery 005 to the battery position 031 of the electronic device 000, that is, the battery 005 is assembled to the battery position 031 of the electronic device 000 in a manner that the center line of the battery body 100 (such as the center line O2 of the battery body 100 in the X-axis direction shown in the figure) is aligned with the center line of the battery position 031 (such as the center line O1 of the battery position 031 in the X-axis direction shown in the figure). The related assembly method uses the position on the battery body 100 and the position of the battery position 031 as the reference position when assembling the battery 005, which will cause tolerances such as incoming material tolerance and assembly tolerance to be accumulated, and when the battery 005 is moved to the battery position 031, the BTB connector male seat 230 and the BTB connector female seat 061 are misaligned.

[0131] for example, Fig. 9 In the embodiment, the tolerance accumulated in the X-axis direction causes the BTB connector male socket 230 and the BTB connector female socket 061 to be misaligned in the X-axis direction. Fig. 9 (a) shows the situation that the BTB connector male socket 230 is misaligned in the negative direction of the X-axis relative to the BTB connector female socket 061. In this case, the flexible circuit board 200 is redundant in the X-axis direction; Fig. 9 (b) shows the situation where the BTB connector male socket 230 is misaligned relative to the BTB connector female socket 061 in the positive direction of the X-axis. In this case, the flexible circuit board 200 is insufficient in length in the X-axis direction.

[0132] It should be noted that Fig. 9 In the case where the BTB connector male socket 230 and the BTB connector female socket 061 of the mainboard 006 are misaligned in the X-axis direction, the BTB connector male socket 230 of the battery 005 and the BTB connector female socket 061 of the mainboard 006 are forcibly electrically connected, and the flexible circuit board 200 may have the following two situations: First, corresponding to Fig. 9 In (a), such as Fig.10 As shown in (a) of FIG. 1 , the flexible circuit board 200 is redundant in the X-axis direction, causing the flexible circuit board 200 to bend back toward the main board 006. Figure 2 , because the side of the flexible circuit board 200 facing away from the main board 006 is the screen 001, the flexible circuit board 200 is arched away from the main board 006, which may easily lead to reliability problems such as white spots on the screen 001. In some other embodiments, the side of the flexible circuit board 200 facing away from the main board 006 may also be the back cover 002. In this case, the flexible circuit board 200 is arched away from the main board 006, which may easily lead to appearance problems such as bulges in the corresponding area of ​​the back cover 002.

[0133] Second, corresponding to Fig. 9 (b) in the above example Fig.10As shown in (b), the flexible circuit board 200 is pulled due to the insufficient length of the flexible circuit board 200 in the X-axis direction. Figure 2 When the flexible circuit board 200 is pulled, the flexible circuit board 200 may be torn or the BTB connector male socket 230 and the BTB connector female socket 061 may not fit firmly, thereby reducing the reliability of the electrical connection between the battery 005 and the main board 006.

[0134] It should be noted that in some other embodiments, the relevant assembly method may also assemble the battery 005 in a manner that the center line of the battery body 100 in the Y-axis direction is aligned with the center line of the battery position 031 in the Y-axis direction. In this case, the above tolerance will cause the BTB connector male socket 230 and the BTB connector female socket 061 to be misaligned in the Y-axis direction. The misalignment of the BTB connector male socket 230 and the BTB connector female socket 061 in the Y-axis direction may also easily cause the flexible circuit board 200 to be arched or pulled, thereby causing the above problem.

[0135] Based on this, in order to solve the above-mentioned problem caused by the misalignment of the BTB connector male socket 230 and the BTB connector female socket 061, which causes the flexible circuit board 200 to be arched or pulled, the embodiments of the present application provide two solutions.

[0136] First, the first solution is described.

[0137] The first solution is a new battery 005 assembly method that can be used to achieve Figure 2 The assembly of the battery 005 in the electronic device 000 shown in FIG. Fig.11 and Fig.12 Provide explanation.

[0138] For example, please refer to Fig.11 , Fig.11 A schematic flow chart of a method for assembling a battery 005 provided in an embodiment of the present application is applied to a mechanical device for assembling the battery 005. Fig.12 for Fig.11 The structural assembly diagram corresponding to the assembly method shown Figure 1 . Fig.11 The assembly method shown includes the following steps S101 to S104.

[0139] Step S101, installing the mainboard to one side of the battery position.

[0140] For example, please refer to Fig.12 The mainboard 006 is located on one side of the battery position 031 in the Y-axis direction, specifically on one side of the positive direction of the Y-axis. Based on this, the mainboard 006 is specifically installed on one side of the battery position 031 in the positive direction of the Y-axis.

[0141] also, Fig.12 In the figure, the current position of battery 005 is the battery position indicated by the solid line, which is located on one side of battery position 031 in the Y-axis direction and at the position corresponding to battery position 031 in the Y-axis direction. Fig.12 The corresponding position of the battery position 031 in the Y-axis direction is: the position of the battery position 031 arranged in the X-axis direction between the reference lines where the two edge lines are located, that is, the position between the reference line P1 and the reference line P2.

[0142] It should be noted that the battery is located at the position corresponding to the battery position 031 in the Y-axis direction, which does not limit whether the battery 005 is located at the position corresponding to the battery position 031 in the X-axis direction and the Z-axis direction. For example, in some other embodiments, the current position of the battery 005 can be directly at the battery position 031. In this case, the battery 005 is located at both the position corresponding to the battery position 031 in the Y-axis direction and the position corresponding to the battery position 031 in the X-axis direction and the Z-axis direction. It can be seen that the current position of the battery 005 is at the battery position 031, which also belongs to the situation where the battery is located at the position corresponding to the battery position 031 in the Y-axis direction. The definition of the battery being located at the position corresponding to the battery position 031 in the Y-axis direction and the position corresponding to the Z-axis direction can refer to the meaning of the battery being located at the position corresponding to the battery position 031 in the X-axis direction.

[0143] In addition, in some other embodiments, the current position of the battery 005 may not be at the position corresponding to the battery position 031. For example, it may not be at the position corresponding to the battery position 031 in the Y-axis direction, or it may not be at the position corresponding to the battery position 031 in the X-axis direction, or it may not be at the position corresponding to the battery position 031 in the Z-axis direction, etc. This embodiment of the application does not limit this.

[0144] Step S102, obtaining a first position of the flexible circuit board of the battery and a second position of the main board.

[0145] In the specific implementation process, in step S101, the mechanical device may include a mechanical arm for clamping the battery and a camera installed on the mechanical arm, such as a charge-coupled device (CCD) camera. When the mechanical arm of the mechanical device clamps the battery and moves, it continuously takes pictures through the installed camera. The image sensor (such as CCD) of the camera takes pictures of the flexible circuit board containing the battery and the main board (such as Fig.12 Image recognition is performed on the photo corresponding to the viewing angle shown in the figure) to obtain the above-mentioned first position and second position.

[0146] The first position is used to indicate the position of the BTB connector male socket of the flexible circuit board. It should be noted that the position on the flexible circuit board that is not prone to relative movement relative to the BTB connector male socket can be used to indicate the first position of the BTB connector male socket of the motherboard.

[0147] As a non-limiting embodiment, in order to facilitate image recognition, the first position can be selected as the edge position of a part on the flexible circuit board. Since the edge position has a clear boundary with the surrounding part, it can be used as a feature for image recognition, thereby locating the first position more quickly.

[0148] for example, Fig.12 In the X-axis direction (ie, the first direction), an edge S1 of the second plate portion 220 facing away from the first plate portion 210 is the first position.

[0149] It should be noted that the first end of the second plate portion 220 is called a 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 a 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. If it is used as a reference position during assembly, it is more likely to cause the BTB connector male socket 230 and the BTB connector female socket 061 to be misaligned in the X-axis direction, thereby making it impossible to achieve electrical connection between the BTB connector male socket 230 and the BTB connector female socket 061. Based on this, the closer the second plate portion 220 is to the free end in the X-axis direction, the less suitable it is to be used as the first position.

[0150] 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 represent the position of the second end (free end) of the second plate portion 220 in the X-axis direction. Based on this, this embodiment selects the first position as the edge of one side 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 farthest from the free end in the X-axis direction as the first position. Compared with other positions on the second plate portion 220, this position is less likely to move and has little effect on the misalignment of the BTB connector male socket 230 and the BTB connector female socket 061 in the X-axis direction.

[0151] Of course, in some other embodiments, the first position is not limited to the edge S1. Fig.12 In the case where the first board portion 210 of the flexible circuit board 200 is a rigid structure, the first position may also be a position on the first board portion 210. For example, the first position may be Fig.12 The illustrated edge S2 of the first plate portion 210 , the edge S3 of the first plate portion 210 , and so on.

[0152] The position and shape of the first plate portion 210 constructed as a rigid structure are not easy to change relatively. The position on the first plate portion 210 constructed as a rigid structure is selected to represent the first position of the BTB connector male socket 230 as a reference position during assembly, which has little effect on the misalignment of the BTB connector male socket 230 and the BTB connector female socket 061 in the X-axis direction, thereby enabling electrical connection between the BTB connector male socket 230 and the BTB connector female socket 061.

[0153] It should be noted that the first position is not limited to Fig.12 The first position is shown in the figure. In other embodiments, the first position may also be other positions on the flexible circuit board 200 .

[0154] The second position is used to represent the position of the BTB connector socket of the motherboard. It should be noted that the position on the motherboard that is not easy to move relative to the BTB connector socket can be used to represent the second position of the BTB connector socket of the motherboard.

[0155] As a non-limiting embodiment, in order to facilitate image recognition, the second position can be selected as the edge position of a certain part on the mainboard. Since the edge position has a clear boundary with the surrounding parts, it can be used as a feature of image recognition, so as to locate the second position more quickly. For example, the second position can be selected as the edge of the copper leakage area on the mainboard. For example, Fig.12 One side edge S4 of the two side edges of the copper leakage region 062 arranged in the X-axis direction is the second position.

[0156] Since the copper leakage area 062 of the mainboard 006 has a significant color difference compared to other positions of the mainboard 006 (the mainboard 006 is usually green), it is easy to be distinguished during the image recognition process. Based on this, in this embodiment, the edge of the copper leakage area 062 of the mainboard 006 is used as the second position, which is easy to be identified during the image recognition process, thereby facilitating the rapid and accurate capture of the second position.

[0157] It should be noted that the second position is not limited to Fig.12 The illustrated position is, in other embodiments, the second position may also be other positions on the main board 006.

[0158] Step S103, assembling the battery to a target position of the battery position according to the first position and the second position, wherein the target position of the battery position is a position where the BTB connector male socket and the BTB connector female socket correspond to each other.

[0159] Please refer to Fig.12, the BTB connector male socket 230 and the BTB connector female socket 061 correspond to each other, which may be that the BTB connector male socket 230 and the BTB connector female socket 061 correspond to each other in the X-axis direction and / or the Y-axis direction. The BTB connector male socket 230 and the BTB connector female socket 061 correspond to each other in a certain direction, which means that the BTB connector male socket 230 and the BTB connector female socket 061 are not misaligned in this direction or the misalignment is small enough, so small that the arching or pulling phenomenon of the flexible circuit board 200 caused by the BTB connector male socket 230 buckling the BTB connector female socket 061 is not obvious, and is not enough to offset the screen or the back cover. The threshold of the misalignment can be set as needed.

[0160] It should be noted that the BTB connector male socket 230 and the BTB connector female socket 061 correspond to each other in the X-axis direction and / or the Y-axis direction, and are both regarded as corresponding to each other. In this case, step S103 is equivalent to: according to the first position and the second position, assembling the battery to the target position where the BTB connector male socket and the BTB connector female socket correspond to each other in the X-axis direction and / or the Y-axis direction.

[0161] Fig.12 In the embodiment, since the space occupied by the flexible circuit board 200 in the Y-axis direction is much smaller than the space occupied in the X-axis direction, even if the BTB connector male socket 230 and the BTB connector are misaligned in the Y-axis direction, the redundancy or insufficient length of the flexible circuit board 200 in the Y-axis direction is relatively light, and the arching or pulling phenomenon caused by this 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.

[0162] Based on this, as a non-limiting example, Fig.12 In the embodiment, the target position is a position where the BTB connector male socket 230 and the BTB connector female socket 061 correspond to each other in the X-axis direction (i.e., the first direction). In this case, the above step S103 is: according to the first position and the second position, assemble the battery 005 to the target position where the BTB connector male socket 230 and the BTB connector female socket 061 correspond to each other in the X-axis direction. For example, Fig.12 In the embodiment, according to the edge S1 and the edge S4, the battery 005 is assembled to a target position where the BTB connector male socket 230 and the BTB connector female socket 061 correspond to each other in the X-axis direction.

[0163] In step S103, assembling the battery to the target position of the battery position may involve the step of moving the battery from the current position to the target position of the battery position. Fig.12In the case where the battery is located at the battery position indicated by the dotted line in the battery position 031 shown in the figure, the BTB connector male socket 230 corresponds to the BTB connector female socket 061, so the target position can be the battery position indicated by the dotted line in 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 in the figure to the target position indicated by the dotted line in the battery position 031 shown in the figure.

[0164] Depend on Fig.12 It can be seen that the movement of the battery 005 to the target position of the battery position 031 does not require that all components of the battery 005 be moved into the battery position 031. For example, the movement of the battery 005 to the target position of the battery position 031 may be that the main body of the battery 005 is moved to the target position of the battery position 031 and a portion of the flexible circuit board 200 extends out of the battery position 031. In addition, assembling the battery 005 to the target position of the battery position 031 may also involve steps related to the assembly of the battery 005, such as aligning and fastening the battery 005 in the Z-axis direction and fixing the battery 005, which are not limited in the embodiments of the present application.

[0165] Step S104, snapping the BTB connector male socket and the BTB connector female socket together to achieve electrical connection.

[0166] Please combine Fig.12 When assembling the battery 005, the first position of the flexible circuit board 200 of the battery 005 is used to represent the position of the BTB connector male socket 230, and the second position of the main board 006 is used to represent the position of the BTB connector female socket 061, and these are used as reference positions for assembling the battery 005.

[0167] Compared to the solution of characterizing the position of the BTB connector male socket 230 by other structures other than the flexible circuit board 200 (such as the center line of the battery 005 used in the relevant assembly method), and characterizing the position of the BTB connector female socket 061 by other structures other than the main board 006 (such as the center line of the battery position 031 used in the relevant assembly method), since the first position is the position on the flexible circuit board 200 where the BTB connector male socket 230 is located, and the second position is the position on the main board 006 where the BTB connector female socket 061 is located, since the incoming material tolerance of the battery position 031, the incoming material tolerance of the battery 005 body, the assembly tolerance between the battery position 031 and the battery 005 body, and the assembly tolerance between the battery 005 body and the flexible circuit board 200 are not introduced, the first position and the second position can respectively more accurately characterize the position of the BTB connector male socket 230 and the position of the BTB connector female socket 061.

[0168] Based on this, compared with the relevant assembly method, using the first position of the flexible circuit board 200 of the battery 005 and the second position of the main board 006 as reference positions during assembly has little effect on the misalignment of the BTB connector male socket 230 and the BTB connector female socket 061, thereby improving the misalignment of the BTB connector male socket 230 and the BTB connector female socket 061 in a certain direction or multiple directions, so that the BTB connector male socket 230 and the BTB connector female socket 061 correspond to each other in a certain direction or multiple directions. When the BTB connector male socket 230 and the BTB connector female socket 061 correspond to each other in one direction or multiple directions, snapping the BTB connector male socket 230 and the BTB connector female socket 061 together can improve the arching or pulling phenomenon of the flexible circuit board 200, thereby solving reliability problems such as white spots on the screen 001 caused by the arching of the flexible circuit board 200 or the appearance problem of the arching of the corresponding area of ​​the back cover 002, and can also solve the problem of tearing or poor contact caused by the pulling of the flexible circuit board 200, thereby improving the reliability of the electrical connection between the battery 005 and the main board 006.

[0169] In addition, for Fig.12 In the case where the battery 005 is assembled to the target position where the BTB connector male seat 230 and the BTB connector female seat 061 correspond to each other in the X-axis direction, since the BTB connector male seat 230 and the BTB connector female seat 061 correspond to each other in the X-axis direction, when the BTB connector male seat 230 and the BTB connector female seat 061 are buckled together, it is not easy for the flexible circuit board 200 to be bulged due to redundancy in the X-axis direction, or to be pulled due to insufficient length in the X-axis direction, thereby solving the problem of Fig.10 The problem described.

[0170] 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, and the second board portion 220 of the flexible circuit board 200 can move relative to the first board portion 210 in the X-axis direction. Figure 5 The battery 005 of the flexible circuit board 200 shown in the figure adopts Fig. 9 The related assembly method shown in the figure can also be used to assemble, and the position of the BTB connector male socket 230 of the second board part 220 in the X-axis direction can be adjusted to make the BTB connector male socket 230 and the BTB connector female socket 061 engage with each other without the flexible circuit board 200 being arched or pulled.

[0171] However, compared to Figure 5 As for the flexible circuit board 200 shown in FIG. Figure 4The flexible circuit board 200 shown is not a double-layer structure bent 180° in the X-axis direction. The second board portion 220 of the flexible circuit board 200 cannot move relative to the first board portion 210 in the X-axis direction, so the position of the BTB connector male socket 230 of the second board portion 220 in the X-axis direction cannot be adjusted. Fig. 9 The relevant assembly method shown will Figure 2 When the battery 005 in the battery 005 is moved to the 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, so that the misalignment of the BTB connector male socket 230 of the battery 005 and the BTB connector female socket 061 of the main board 006 in the X-axis direction cannot be improved, thereby causing the BTB connector male socket 230 of the battery 005 and the BTB connector female socket 061 of the main board 006 to be unable to achieve electrical connection. Based on this, Figure 2 Battery 005 is suitable for Fig.11 The assembly method shown is used to improve the misalignment of the first electrical connection portion and the second electrical connection portion in the X-axis direction.

[0172] It should be noted that Fig.11 The assembly method of the battery 005 shown in the figure can also be used to realize the assembly of the battery 005 in other electronic devices 000, for example, in other electronic devices 000 having Figure 5 The assembly of the battery 005 of the flexible circuit board 200 shown in FIG. 1 is shown in FIG. 1 . In this case, there is no need to adjust the position of the second board portion 220 in the X-axis direction to improve the misalignment of the BTB connector male socket 230 and the BTB connector female socket 061 in the X-axis direction.

[0173] Next, continue to combine Fig.11 and Fig.12 , taking the target position as the position where the BTB connector male socket 230 and the BTB connector female socket 061 correspond to each other in the X-axis direction as an example, step S103 is described in detail.

[0174] As a non-limiting example, please continue to refer to Fig.11 When the current position is the position corresponding to the battery position 031 in the Y-axis direction, and the target position is the position where the BTB connector male socket 230 and the BTB connector female socket 061 correspond in the X-axis direction, step S103 may include the following steps S1031 to S1033.

[0175] Step S1031, determining the actual distance between the first position and the second position in the X-axis direction.

[0176] 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.

[0177] Continue with Fig.12 As an example, taking the first position as edge S1 and the second position as edge S4, when the battery 005 is in the current position indicated by the solid line, the absolute value of the difference between the X coordinate of the first reference line L1 passing through the edge S1 along the Y-axis direction and the X coordinate of the second reference line L2 passing through the edge S4 along the Y-axis direction is the actual spacing △L1 between the first position and the second position in the X-axis direction.

[0178] It should be noted that Fig.12 The first position and the second position in the figure are just the edge S1 and the edge S4 extending along the Y-axis direction. Therefore, the first reference line L1 extending along the Y-axis direction just coincides with the edge S1, and the second reference line L2 extending along the Y-axis direction just coincides with the edge S4. In some other embodiments, the first position and the second position are in other forms. For example, the first position and the second position can also be positions corresponding to two points, in which case the first reference line passes through one of the two points along the Y-axis direction, and the second reference line passes through the other of the two points along the Y-axis direction; for another example, the first position and the second position can also be positions corresponding to two irregular shapes, in which case the first reference line passes through a point on one of the shapes along the Y-axis direction, and the second reference line passes through a point on the other shape along the Y-axis direction.

[0179] Fig.12 In the embodiment, since it is necessary to obtain the actual spacing △L1 between the first position and the second position in the X-axis direction, when the first position is selected, the side edge S1 of the second board portion 220 facing away from the first board portion 210 in the X-axis direction is taken as the first position; when the second position is selected, the side edge S2 of the copper leakage area 062 in the X-axis direction is taken as the second position, which helps to obtain the actual spacing △L1 between the first position and the second position in the X-axis direction, thereby helping to make the BTB connector male socket 230 and the BTB connector female socket 061 correspond to each other in the X-axis direction.

[0180] Step S1032, obtaining a design spacing between the first position and the second position in the X-axis direction.

[0181] The design spacing between the first position and the second position in the X-axis direction is the spacing between the first position and the second position in the X-axis direction designed during the design stage of the electronic device 000 so that the BTB connector male socket 230 and the BTB connector female socket 061 are not misaligned in the X-axis direction when the battery 005 is assembled to the battery position 031. The design spacing can be determined and stored during the design stage of the electronic device 000 so that it can be called when executing the assembly method.

[0182] Continue with Fig.12 As an example, taking the first position as edge S1 and the second position as edge S4 as an example, in order to facilitate the distinction from the battery 005 at the target position, the battery position indicated by the dotted line outside the battery position 031 is illustrated to illustrate 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 the edge S1 of the battery 005 indicated by the dotted line along the Y axis direction and the X coordinate of the second reference line L2 passing through the edge S4 along the Y axis direction can be understood as the designed spacing △L3 between the first position and the second position in the X axis direction.

[0183] The execution order of the above step S1031 and step S1032 is not specific. Fig.12 In the example, the actual spacing △L1 and the designed spacing △L3 are explained by taking the battery position indicated by the solid line as being offset in the negative direction of the X axis relative to the battery position indicated by the dotted line outside the battery position 031. In this case, the actual spacing △L1 is greater than the designed spacing △L3. In some other embodiments, such as Fig.13 As shown, the battery position indicated by the solid line can also be offset in the positive direction of the X axis relative to the battery position indicated by the dotted line outside the battery position 031. In this case, the actual spacing △L1 is smaller than the designed spacing △L3, or, as Fig.14 As shown, the battery position indicated by the solid line may not be offset in the X-axis direction relative to the battery position indicated by the dotted line outside the battery position 031. In this case, the actual spacing △L1 is equal to the designed spacing △L3. This embodiment of the present application does not limit this.

[0184] Step S1033, assembling the batteries to the target positions of the battery positions according to the actual spacing and the designed spacing.

[0185] Depending on whether the actual spacing and the designed spacing are equal, step S1033 may be different, which will be discussed below in different cases.

[0186] First, if the actual spacing is not equal to the designed spacing, in step S1033, when the battery 005 is assembled from the current position to the target position, the target movement amount is moved along the movement direction in the X-axis direction. The movement direction is determined according to the size relationship between the actual spacing and the designed spacing; the target movement amount is determined according to the absolute value of the difference between the actual spacing and the designed spacing.

[0187] Since the design spacing is the spacing between the first position and the second position in the X-axis direction when the BTB connector male socket 230 and the BTB connector female socket 061 are not misaligned in the X-axis direction, the actual spacing is not equal to the design spacing, which can indicate that the BTB connector male socket 230 and the BTB connector female socket 061 are misaligned in the X-axis direction.

[0188] The size relationship between the actual spacing and the designed spacing can represent the misalignment direction of the BTB connector male socket 230 and the BTB connector female socket 061 in the X-axis direction. The battery 005 moves in the opposite direction of the misalignment direction (the opposite direction of the misalignment direction is referred to as the moving direction in the embodiment of the present application), which can improve the misalignment of the BTB connector male socket 230 relative to the BTB connector female socket 061 in the X-axis direction, and promote the BTB connector male socket 230 and the BTB connector female socket 061 to correspond to each other in the X-axis direction.

[0189] 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 to each other in the X-axis direction, in step S1033, the battery 005 is assembled from the current position to the target position and moves along the moving direction in the X-axis direction. Since the magnitude 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, based on this, the moving direction in this embodiment is determined according to the magnitude relationship between the actual spacing and the designed spacing.

[0190] Among them, the absolute value of the difference between the actual spacing and the designed spacing can represent the misalignment amount of the BTB connector male socket 230 and the BTB connector female socket 061 in the X-axis direction. The misalignment amount is equal to the required movement amount of the battery 005 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. Based on this, in this embodiment, the target movement amount is determined according to the absolute value of the difference between the actual spacing and the designed spacing, which is equivalent to being determined according to the required movement amount, which helps to make the BTB connector male socket 230 and the BTB connector female socket 061 correspond to each other in the X-axis direction.

[0191] Continue with Fig.12 For example, Fig.12 It shows the situation where the actual spacing is larger than the designed spacing.

[0192] In the X-axis direction, the battery position indicated by the solid line is offset in the negative direction of the X-axis relative to the battery position indicated by the dotted line outside the battery position 031, resulting in the actual spacing being greater than the designed spacing, and the BTB connector male socket 230 is misaligned in the negative direction of the X-axis relative to the BTB connector female socket 061. In this case, the misalignment direction of the BTB connector male socket 230 relative to the BTB connector female socket 061 in the X-axis direction is the negative direction of the X-axis (that is, the first misalignment direction is the negative direction of the X-axis). It can be seen that Fig.12 In the figure, the actual spacing is greater than the designed spacing, which indicates that the misalignment direction is in the negative direction of the X-axis. The battery 005 is assembled from the current position indicated by the solid line to the target position indicated by the dotted line in the battery position 031, and needs to be moved along the positive direction of the X-axis, that is, the moving direction is in the positive direction of the X-axis (that is, the first moving direction is in the positive direction of the X-axis).

[0193] It should be noted that the first misalignment direction is opposite to the first movement direction. The first misalignment direction is one of the first direction and the second direction of the first direction, and the first movement direction is the other of the first direction and the second direction of the first direction. Fig.12 In the example, the positive direction of the X-axis is the first orientation of the first direction, and the negative direction of the X-axis is the second orientation of the first direction. Based on this, Fig.12 The case where the first misaligned orientation is the second orientation of the first direction and the first moving orientation is the first orientation of the first direction is shown. In some other embodiments, the first misaligned orientation may also be the first orientation of the first direction and the first moving orientation may also be the second orientation of the first direction.

[0194] visible, Fig.12 In the embodiment, the first misalignment direction represented by the magnitude relationship between the actual deviation and the design deviation is opposite to the first movement direction. Based on this, the movement direction can be determined based on the magnitude relationship between the actual deviation and the design deviation.

[0195] and, Fig.12 In the figure, the difference between the actual spacing and the designed spacing is △L13 (△L13 in the figure is the difference between the X coordinate of the first reference line L1 and the X coordinate of the third reference line L3), and the displacement of the BTB connector male seat 230 and the BTB connector female seat 061 in the X-axis direction is the absolute value of △L45 (△L45 in the figure 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 roughly equal to the absolute value of △L45. It can be seen that the absolute value of the difference between the actual spacing and the designed spacing can characterize the displacement of the BTB connector male seat 230 and the BTB connector female seat 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 the reference line P3 and the reference line P5) can be determined based on the absolute value of the difference between the actual spacing and the designed spacing.

[0196] In some other embodiments, such as Fig.13 As shown, Fig.13 It shows the situation where the actual spacing is smaller than the designed spacing.

[0197] In the X-axis direction, the battery position indicated by the solid line is offset in the positive direction of the X-axis relative to the battery position indicated by the dotted line outside the battery position 031, resulting in the actual spacing being greater than the designed spacing, and the BTB connector male socket 230 is misaligned in the positive direction of the X-axis relative to the BTB connector female socket 061. In this case, the misalignment direction of the BTB connector male socket 230 relative to the BTB connector female socket 061 in the X-axis direction is the positive direction of the X-axis (that is, the second misalignment direction is the positive direction of the X-axis). It can be seen that Fig.13 In the figure, the actual spacing is smaller than the designed spacing, which indicates that the misalignment direction is in the positive direction of the X-axis. The battery 005 is assembled from the current position indicated by the solid line to the target position indicated by the dotted line in the battery position 031, and needs to be moved along the negative direction of the X-axis, that is, the moving direction is in the negative direction of the X-axis (that is, the second moving direction is in the negative direction of the X-axis).

[0198] The second misalignment direction is opposite to the second movement direction, the second misalignment direction is the other of the first direction and the second direction of the first direction, and the second movement direction is one of the first direction and the second direction of the first direction. The second misalignment direction is opposite to the first misalignment direction, and the second movement direction is opposite to the first movement direction. Fig.13 , the positive direction of the X-axis is the first orientation of the first direction, and the negative direction of the X-axis is the second orientation of the first direction. Therefore, Fig.13 The case where the second misaligned orientation is the first orientation of the first direction and the second moving orientation is the second orientation of the first direction is shown. In some other embodiments, the second misaligned orientation may also be the second orientation of the first direction and the second moving orientation may also be the first orientation of the first direction.

[0199] It can be seen that the second misalignment direction represented by the magnitude relationship between the actual deviation and the design deviation is opposite to the second movement direction. Based on this, the movement direction can be determined based on the magnitude relationship between the actual deviation and the design deviation.

[0200] and, Fig.13In the figure, the difference between the actual spacing and the designed spacing is △L13 (△L13 in the figure is the difference between the X coordinate of the first reference line L1 and the X coordinate of the third reference line L3), and the displacement of the BTB connector male seat 230 and the BTB connector female seat 061 in the X-axis direction is the absolute value of △L45 (△L45 in the figure 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 roughly equal to the absolute value of △L45. It can be seen that the absolute value of the difference between the actual spacing and the designed spacing can characterize the displacement of the BTB connector male seat 230 and the BTB connector female seat 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 the reference line P3 and the reference line P5) can be determined based on the absolute value of the difference between the actual spacing and the designed spacing.

[0201] Second, the actual spacing is equal to the designed spacing. In step S1033, when the battery 005 is assembled from the current position to the target position, the battery 005 does not move in the X-axis direction.

[0202] Since the design spacing is the spacing between the first position and the second position in the X-axis direction when the BTB connector male socket 230 and the BTB connector female socket 061 are not misaligned in the X-axis direction, the actual spacing is equal to the design spacing, which can indicate that the BTB connector male socket 230 and the BTB connector female socket 061 are not misaligned in the X-axis direction. Based on this, in this case, during the process of assembling the battery 005 to the target position, the embodiment keeps the battery 005 from moving in the X-axis direction, so that the BTB connector male socket 230 and the BTB connector female socket 061 can be maintained without misalignment in the X-axis direction, so that the battery 005 is assembled to the target position where the BTB connector male socket 230 and the BTB connector female socket 061 correspond to each other in the X-axis direction.

[0203] For example, Fig.14 As shown, Fig.14 It illustrates the situation where the actual spacing △L1 is equal to the designed spacing △L3.

[0204] In the X-axis direction, the battery position indicated by the solid line is not offset relative to the battery position indicated by the dotted line outside the battery position 031 in the X-axis direction, so that the actual spacing is equal to the designed spacing (the first reference line L1 and the third reference line L3 coincide with each other), 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 with each other). It can be seen that Fig.14In the embodiment, the actual spacing is equal to the designed spacing, which indicates 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, the embodiment moves the battery 005 to the battery position 031 while maintaining the position of the battery 005 in the X-axis direction, so that the battery 005 can be assembled to the target position.

[0205] Figure 12 to Figure 14 In the figure, the battery position indicated by the solid line is located on one side of the battery position 031 in the Y-axis direction, and is not located in the battery position 031. Therefore, in step S1033, assembling the battery 005 to the target position indicated by the dotted line in the battery position 031 involves moving the battery 005 to the target position indicated by the dotted line in the battery position 031 and assembling it. Figure 12 to Figure 13 For the embodiment shown, moving the battery 005 to the target position indicated by the dotted line in the battery position 031 involves movement in the X-axis direction, the Y-axis direction, and the Z-axis direction; Fig.14 In the embodiment shown, since it does not move in the X-axis direction, moving the battery 005 to the target position indicated by the dotted line in the battery position 031 involves movement in the Y-axis direction and the Z-axis direction. The embodiment of the present application does not impose any special restrictions on the specific process of moving the battery 005 to the target position indicated by the dotted line in the battery position 031. For example, Fig.12 In the figure, the battery 005 can first move in the Y-axis direction, then move in the X-axis direction, and finally move in the Z-axis direction, so as to move to the target position indicated by the dotted line in the battery position 031; it can also first move in the X-axis direction, then move in the Y-axis direction, and finally move in the Z-axis direction, so as to move to the target position indicated by the dotted line in the battery position 031.

[0206] In some other embodiments, the battery position indicated by the solid line is located at the battery position 031. For the case where the actual spacing is not equal to the design spacing, the current position and the target position of the battery 005 are spaced only in the X-axis direction, so assembling the battery 005 to the target position involves moving the battery 005 to the target position in the X-axis direction and assembling it. For the case where the actual spacing is equal to the design spacing, the battery 005 is already at the target position, so assembling the battery 005 to the target position involves assembling the battery 005.

[0207] Combine the following Fig.15 , taking the current position of the battery as the battery position as an example, Fig.11 Step S1033 in the following is described in detail.

[0208] For example, please refer to Fig.15 , Fig.15 A schematic diagram of a battery assembly solution provided in an embodiment of the present application. The battery assembly solution includes the following steps S1033a to S1033d3.

[0209] S1033a, determining the size relationship between the actual spacing and the designed spacing.

[0210] When the actual spacing is greater than the designed spacing, a movement compensation algorithm of the first movement direction is executed. The compensation algorithm of the first movement direction includes step S1033b1, step S1033c1, step S1033d1 and step S1033e.

[0211] When the actual spacing is smaller than the designed spacing, a movement compensation algorithm of the second movement direction is executed. The compensation algorithm of the second movement direction includes step S1033b2, step S1033c2, step S1033d2 and step S1033e.

[0212] When the actual spacing is equal to the designed spacing, step S103e is executed.

[0213] Step S1033b1, determining the moving direction to be the first moving direction.

[0214] Step S1033c1, determine the target movement amount.

[0215] There is no particular order in which step S1033b1 and step S1033c1 are executed.

[0216] In some embodiments, the target movement amount is the smaller value 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 movement amount that the battery position can provide to the battery in the first movement direction. In this embodiment, the smaller value of the required movement amount and the first movable amount is used as the target movement amount in the compensation algorithm of the first movement direction, so that the battery will not be moved out of the battery position and cannot be assembled.

[0217] Due to the different magnitude relationships between the required moving amount and the first movable amount, step S1033c1 specifically includes the following three situations: The first case: when the required moving amount is less than the first movable amount, the required moving amount is determined as the target moving amount.

[0218] The second case: when the required moving amount is equal to the first movable amount, the required moving amount (ie, the first movable amount) is determined as the target moving amount.

[0219] The third case: when the required moving amount is greater than the first movable amount, the first movable amount is determined as the target moving amount.

[0220] In some embodiments, Fig.12As shown, when the battery is at the current position indicated by the solid line, the center line O1 of the battery position 031 and the center line O2 of the battery body 100 are on the same straight line. In this case, the first movable amount is (AB) / 2. Among them, A is the accommodation size of the battery position 031 in the X-axis direction, and B is the size of the battery body 100 in the X-axis direction. In the specific implementation process, it can be adopted Fig. 9 The assembly method shown moves the battery 005 to the current position where the center line O1 and the center line O2 are collinear.

[0221] Generally, the electronic device 000 meets the following conditions when it is designed: when the BTB connector male socket 230 and the BTB connector female socket 061 are not misaligned in the X-axis direction, the center line O1 of the battery position 031 in the X-axis direction and the center line O2 of the battery body 100 in the X-axis direction are in the same straight line. In this way, the battery 005 can be assembled to the battery position 031 in a relatively centered position, so that the weight of the electronic device 000 is more balanced in the X-axis direction. When the center line O1 and the center line O2 are in the same straight line, the gap between the battery position 031 and the battery body 100 on one side of the center line O1 is (AB) / 2. Based on this, the amount of movement that the battery position 031 can provide to the battery 005 in the positive direction of the X-axis is (AB) / 2, that is, the first movable amount is (AB) / 2. For example, (AB) / 2 is greater than 0.1 cm.

[0222] In other embodiments, when the battery is at the current position indicated by the solid line, the center line O1 of the battery position 031 may not be on the same straight line as the center line O2 of the battery body 100. In this case, the first movable amount is the distance △P32 between the reference line P2 where the edge of one side of the battery position 031 in the positive direction of the X-axis is located and the reference line P3 where the edge of one side of the battery body 100 in the positive direction of the X-axis is located. In the figure, because the center line O1 and the center line O2 of the battery body 100 are on the same straight line, △P32=(AB) / 2.

[0223] Step S1033d1, assembling the battery after moving the battery in the first direction by the first moving target amount. When the current position of the battery is the battery position, the battery is moved in the first direction by the first moving target amount to reach the target position of the battery position.

[0224] Step S1033d1 specifically includes the following three situations corresponding to the three situations in step S1033c1: Case 1 (corresponding to the first case): the battery is assembled after being moved by a first movable amount in a first direction along a first moving orientation.

[0225] Case 2 (corresponding to the second case): the battery is assembled after being moved by a required amount (ie, a first movable amount) in a first direction along a first moving direction.

[0226] Case 3 (corresponding to the third case): the battery is assembled after being moved by a required amount in the first direction along the first moving direction.

[0227] In some other embodiments, when the required moving amount is greater than the first movable amount, the battery may be regarded as a defective product and discarded (ie, the battery is not assembled).

[0228] Step S1033b2, determining the moving direction to be the second moving direction.

[0229] Step S1033c2, determine the target movement amount.

[0230] There is no particular order in which step S1033b2 and step S1033c2 are executed.

[0231] In some embodiments, the target movement amount is the smaller value 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 movement amount that the battery position can provide to the battery in the second movement direction. In this embodiment, the smaller value of the required movement amount and the second movable amount is used as the target movement amount in the compensation algorithm of the second movement direction, so that the battery will not be moved out of the battery position and cannot be assembled.

[0232] Due to the different magnitude relationships between the required moving amount and the second movable amount, step S1033c2 specifically includes the following three situations: The first case: when the required moving amount is greater than the second movable amount, the second movable amount is determined as the target moving amount.

[0233] The second case: when the required moving amount is equal to the second movable amount, the required moving amount (ie, the second movable amount) is determined as the target moving amount.

[0234] The third case: when the required moving amount is less than the second movable amount, the required moving amount is determined as the target moving amount.

[0235] In some embodiments, Fig.13 As shown, when the battery 005 is at the current position indicated by the solid line, the center line O1 and the center line O2 are on the same straight line. In this case, the second movable amount is (AB) / 2, and the specific analysis can refer to the relevant description of the first movable amount being (AB) / 2.

[0236] In other embodiments, when the battery is at the current position indicated by the solid line, the center line O1 of the battery position 031 may not be on the same straight line as the center line O2 of the battery body 100. In this case, the second movable amount is the distance △P41 between the reference line P1 where the edge of one side of the battery position 031 in the negative direction of the X-axis is located and the reference line P4 where the edge of one side of the battery body 100 in the negative direction of the X-axis is located. In the figure, because the center line O1 and the center line O2 of the battery body 100 are on the same straight line, △P41=(AB) / 2.

[0237] Step S1033d2, assembling the battery after moving the battery in the first direction by the second moving direction to the moving target amount. When the current position of the battery is the battery position, the battery is moved in the first direction by the second moving direction to the moving target amount to reach the target position of the battery position.

[0238] Step S1033d2 specifically includes the following three situations corresponding to the three situations in step S1033c2: Case 1 (corresponding to the first case): the battery is assembled after being moved by a second movable amount in a first direction along a second moving direction.

[0239] Case 2 (corresponding to the second case): the battery is assembled after being moved by a required amount (ie, a second movable amount) in the first direction along the second moving direction.

[0240] Case 3 (corresponding to the third case): the battery 005 is assembled after being moved by the required amount in the first direction along the second moving direction.

[0241] In some other embodiments, when the required moving amount is greater than the second movable amount, the battery may be regarded as a defective product and discarded (ie, the battery is not assembled).

[0242] Step S1033e, alignment assembly. Alignment assembly refers to the assembly steps of moving the battery in the Z-axis direction and fixing the battery, and does not involve moving the battery 005 in the X-axis direction and the Y-axis direction.

[0243] Next, the second solution is described. The second solution is: Figure 1 and Figure 2 The electronic device 000 shown in the figure is provided with a pressure plate. Figure 4 The easily deformable area of ​​the second plate portion 220 is flattened to reduce the risk of the flexible circuit board 200 being arched or pulled.

[0244] For example, please refer to Fig.16 , Fig.16 This is a schematic diagram of the flattened and easily deformable area of ​​the pressure plate provided in an embodiment of the present application.

[0245] The portion of the second plate portion 220 extending to the board surface side of the main board 006 is the easily deformable area 221, and the BTB connector male seat 230 is disposed in the easily deformable area 221. The pressing plate 007 is attached to the side of the easily deformable area 221 facing away from the main board 006, and is fixed to the easily deformable area 221 by the fixing member 008. In this case, Figure 1 and Figure 2 The electronic device 000 shown also includes Fig.16 The pressing plate 007 and the fixing member 008 are shown.

[0246] In this embodiment, a pressure plate 007 is provided on a side of the easily deformable area 221 facing away from the main board 006, and the pressure plate 007 and the easily deformable area 221 are fixed by using a fixing member 008. The force of the fixing member 008 in the thickness direction of the pressure plate 007 (Z-axis direction as shown in the figure) can be utilized to make the pressure plate 007 adhere to the surface of the easily deformable area 221, and flatten the easily deformable area 221, thereby solving reliability problems such as white spots on the screen 001 caused by the easily deformable area 221 arching away from the main board 006 or the appearance problem of bulging in the corresponding area of ​​the back cover 002.

[0247] Optionally, the pressing plate 007 may be a steel sheet with a thickness of 0.25 mm. A steel sheet of this thickness has a strong bending resistance and is not easily bent by the flexible circuit board 200, thereby reducing the risk of the flexible circuit board 200 being arched or pulled.

[0248] Accordingly, the present application embodiment also provides a method for assembling a battery 005, for Fig.16 The assembly of the battery 005 of the electronic device 000 with the press plate 007 is shown.

[0249] For example, please refer to Fig.17 , Fig.17 A schematic flow chart of another method for assembling a battery 005 provided in an embodiment of the present application, which is applied to a mechanical device for assembling a battery 005; Fig.18 for Fig.17 Schematic diagram of structural assembly corresponding to the assembly method shown. Fig.18 The viewing angle of the display is approximately Fig.16 Section view through the cutting line QQ.

[0250] Fig.17 The assembly method of the battery 005 shown includes the following steps S201 to S204: Step S201, moving the battery to the battery position, and extending the flexible circuit board of the battery to the board side of the main board to electrically connect to the main board through the flexible circuit board.

[0251] The area where the flexible circuit board 200 extends to the board surface side of the main board 006 is the easily deformable area 221 .

[0252] Combination Fig.16 , before installing the pressure plate 007, move the battery 005 to the battery position 031 (the battery position 031 is not shown in the figure, combined with Figure 2 It can be seen that the battery is located Fig.16 When the battery 005 is moved to the position shown Figure 2 The battery position 031) and the deformable area 221 of the battery 005 are stacked on the board side of the main board 006, which can be referred to Fig.16 As shown in the left figure.

[0253] Step S202, placing a pressing plate on the side of the easily deformable area facing away from the main board.

[0254] like Fig.18 As shown in (a), the pressing plate 007 is placed on the side of the easily deformable area 221 facing away from the main board 006, that is, the pressing plate 007 is placed on the side facing the upper plate surface of the easily deformable area 221, that is, the side of the easily deformable area 221 facing the positive direction of the Z axis.

[0255] Step S203: Use the cover plate to push the pressing plate toward the side where the easily deformable area is located, so that the easily deformable area is flattened on the surface of the mainboard.

[0256] Among them, a pressure head is arranged on the side of the cover plate facing the pressure plate 007, and 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 fixing positions of the pressure plate 007, and the fixing positions are used to set the fixing piece 008.

[0257] It should be noted that the deformation zone is flattened on the surface of the main board 006 , which means that the easily deformable zone 221 is approximately 180° on the surface of the main board 006 . Fig.18 In the figure, the easily deformable area 221 is flattened on the upper surface of the main board 006 .

[0258] like Fig.18 As shown in (b), using the cover plate 009 to push the pressing plate 007 toward the side where the easy-to-deform area 221 is located refers to the process in which the cover plate 009 presses the pressing plate 007 downward, as shown in the direction of the arrow in the figure. In the process in which the cover plate 009 presses the pressing plate 007 downward, the pressing head 010 first contacts the pressing plate 007.

[0259] As a non-limiting embodiment, the Rockwell hardness of the indenter 010 is 50 to 60 HR. Exemplarily, the indenter 010 can be made of a soft silicone material with a Rockwell hardness of 50 to 60 HR. In this case, during the pressing process of the indenter 010, it comes into soft contact with the pressing plate 007, and is not easy to cause damage to the pressing plate 007. In addition, the indenter with a Rockwell hardness of 50 to 60 HR is a soft material, which is easily deformed during the pressing process so that the cover plate 009 can contact the pressing plate 007, thereby pushing the pressing plate 007 to flatten the easily deformable area 221 on the surface of the main board 006.

[0260] Fig.18 In the embodiment, the fixing position 071 can be a threaded hole, and correspondingly, the fixing member 008 is a fastener such as a bolt that has threads and can be interlocked with the threaded hole.

[0261] It should be noted that Fig.18 The number of the pressing head 010 shown in the figure is one, and the number of the fixing positions 071 on the pressing plate 007 is two. In other embodiments, there may be more fixing positions 071 on the pressing head 010 and the pressing plate 007, and this embodiment of the present application does not limit this.

[0262] Step S204, when the cover plate pushes the pressure plate to flatten the easily deformed area, a fixing piece is respectively provided at two fixing positions to fix the pressure plate and the main board.

[0263] like Fig.18 As shown in (c), in order to achieve the fixing member 008 to fix the pressing plate 007 to the main board 006, the main board 006 has a threaded hole opposite to the threaded hole on the pressing plate 007, so that bolts and other fasteners can pass through the threaded hole on the pressing plate 007 and extend to the threaded hole on the main board 006 for locking, thereby achieving the fixing of the pressing plate 007 to the main board 006. After the bolts and other fasteners are locked, it is presented Fig.18 The state shown in (d).

[0264] In the related art, the cover plate 009 is not provided with a pressure head 010. When two fixing members 008 are used to fix the pressure plate 007, the position of the easily deformable area 221 between the two fixing positions 071 is likely to be arched away from the main board 006, thereby causing reliability problems such as white spots on the screen or appearance problems such as bulging in the corresponding area of ​​the back cover. In this implementation, the pressure head 010 contacts and presses down the pressure plate 007 before the cover plate 009. Based on this, when two fixing members 008 are used to fix the easily deformable area 221, the position of the easily deformable area 221 between the two fixing positions 071 is supported by the pressure head 010 and is not likely to be arched, thereby solving reliability problems such as white spots on the screen or appearance problems caused by the easily deformable area 221 arching away from the main board 006.

[0265] It is also understandable that Fig.11 , Fig.15 as well as Fig.17 The provided embodiments may be implemented in combination or individually, and the embodiments of the present application do not specifically limit this.

[0266] The above are only specific implementation methods of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be covered by the protection scope of the present application.
