Description

Technical Field

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

[0002] Flexible electrical connection structures usually use flexible insulating substrates, such as polyimide, polyester or other polymer materials, to replace traditional rigid substrates, and have many advantages that rigid electrical connection structures do not have. For example, it can be bent, rolled, and folded freely, which meets the needs of electronic products to develop in the direction of high density, miniaturization, and high reliability, and is therefore widely used in electronic equipment.

[0003] In the related art, during the production process of electronic equipment, an automated device can be used to assemble the flexible electrical connection structure in the electronic equipment. The automated assembly production method is conducive to improving assembly efficiency and assembly consistency. In order to ensure the connection stability of the flexible electrical connection structure, the flexible electrical connection structure is usually reasonably designed with a certain amount of redundancy. However, due to the poor management effect of the redundant part of the flexible electrical connection structure during the automated assembly process, the connection position of the flexible electrical connection structure is prone to looseness or connection failure and other poor assembly problems, and may even cause the battery of the electronic device to become loose, thereby reducing the product qualification rate of the electronic device. Summary of the invention

[0004] The present application provides an assembly device for electronic equipment, which is used to solve the problem that poor assembly is likely to occur during the process of assembling a flexible electrical connection structure by the assembly device.

[0005] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions: In a first aspect, an embodiment of the present application provides an assembly device for an electronic device, which is used to assemble a front shell and a circuit board assembly of the electronic device, wherein the circuit board assembly includes a first circuit board assembly, a second circuit board assembly, and a flexible electrical connection structure, wherein the first circuit board assembly and the second circuit board assembly are arranged on the inner surface of the front shell and are spaced apart, and the flexible electrical connection structure is electrically connected between the first circuit board assembly and the second circuit board assembly.

[0006] The assembly device includes a first working unit and a first driving component. The first working unit is used to be arranged on a side of the flexible electrical connection structure that is away from the front shell. The first working unit includes a first working piece and a second working piece arranged along a first direction. The first direction is consistent with the direction in which the first end of the flexible electrical connection structure points to the second end. The end of the flexible electrical connection structure connected to the first circuit board assembly is the first end, and the end of the flexible electrical connection structure connected to the second circuit board assembly is the second end. The first driving component is used to drive the first working piece and the second working piece to move in directions away from each other, so that the first working piece moves toward the first end and the second working piece moves toward the second end.

[0007] According to the assembly device of the embodiment of the present application, there is a redundant part between the first end and the second end of the flexible electrical connection structure. In the process of the first driving component driving the first working piece to move toward the first end, the first working piece can gradually adjust the partial redundancy of the flexible electrical connection structure toward the position close to the first end. In the process of the first driving component driving the second working piece to move toward the second end, the second working piece can gradually adjust the partial redundancy of the flexible electrical connection structure toward the position close to the second end. In this way, it can be ensured that the flexible electrical connection structure has a certain amount of redundancy at the position close to the first electrical connection component and the position close to the second electrical connection component, so as to avoid the first end or the second end being over-tensioned and causing unstable connection with the first circuit board assembly or the second circuit board assembly due to the asymmetric distribution of the redundancy of the flexible electrical connection structure during the assembly process of the electronic device, and to avoid the problem of the connection position being easily loose, which is conducive to improving the problem of poor assembly and improving the connection quality between circuit board assemblies.

[0008] In addition, by adjusting the redundant part of the flexible electrical connection structure toward a position close to the first end and the second end, it is also possible to avoid excessive redundancy in the middle part of the flexible electrical connection structure, thereby avoiding excessive bending of the flexible electrical connection structure during the subsequent assembly of the electronic device, and avoiding excessive redundant parts squeezing the battery to cause it to warp and loosen, thereby reducing the resulting product failure rate.

[0009] In some optional embodiments, the end of the first working piece facing the flexible electrical connection structure is the third end, the end of the first working piece facing away from the flexible electrical connection structure is the fourth end, the third end includes a first side surface and a second side surface, the first side surface faces the second working piece, and the second side surface faces away from the second working piece. Along the direction from the fourth end to the third end, the distance from the first side surface to the second side surface gradually decreases.

[0010] In this way, the first working piece can have more space for movement without increasing the size of the overall device, thereby expanding the travel range of the first working piece along the first direction, and helping to increase the adjustment range when the first working piece adjusts the redundant part of the flexible electrical connection structure; in addition, it also helps to optimize the matching relationship between the first working piece and the flexible electrical connection structure, for example, it helps to optimize the contact angle and pressure.

[0011] In some optional embodiments, along the direction from the fourth end to the third end, the first side surface extends obliquely toward a direction away from the second working piece.

[0012] In this way, the interference between the first working piece and surrounding components can be reduced, which is beneficial to improving the operational flexibility of the first working piece.

[0013] In some optional embodiments, a storage bin is provided on the inner surface of the front housing, the first circuit board assembly and the second circuit board assembly are located on opposite sides of the storage bin, and part of the flexible electrical connection structure is located in the storage bin. The second side surface is adapted to fit with the inner side surface of the storage bin adjacent to the first circuit board assembly.

[0014] In this way, during the movement of the first working piece toward the first end, the assembly device can control the position of the first working piece by means of the matching relationship between the second side surface and the inner side surface of the accommodating bin adapted thereto, so as to achieve accurate control of the travel range of the first working piece, thereby facilitating the control of the adjustment range of the redundant part of the flexible electrical connection structure.

[0015] In some optional embodiments, along the direction from the first end to the second end, the size of the accommodating bin is L1, the stroke of the first working piece moving toward the first end is L2, the stroke of the second working piece moving toward the second end is L3, and the ratio of L2 to L1 and the ratio of L3 to L1 are both greater than or equal to 1 / 5 and less than or equal to 2 / 5.

[0016] If the ratio of L2 to L1 and the ratio of L3 to L1 are less than 1 / 5, the travel range of the first working piece and the second working piece is limited, resulting in limited adjustment effect on the flexible electrical connection structure, which may not meet the assembly requirements; if the ratio of L2 to L1 and the ratio of L3 to L1 are greater than 2 / 5, the travel range of the first working piece is large, which will have higher requirements on the first driving member that drives the first working piece and the second working piece to move. When the ratio of L2 to L1 and the ratio of L3 to L1 are both greater than or equal to 1 / 5 and less than or equal to 2 / 5, within this range, the first working piece and the second working piece can achieve effective adjustment of the flexible electrical connection structure, and at the same time will not have high requirements on the first driving member, which is conducive to cost saving.

[0017] In some optional embodiments, the first working piece includes a first main body and a first head connected to each other, the first main body is connected to the first driving assembly, the first side surface and the second side surface are located on the first head, and the elastic coefficient of the first head is greater than or equal to the elastic coefficient of the first main body.

[0018] In this way, the first head has good elasticity, which can prevent the first working piece from causing damage to the flexible electrical connection structure.

[0019] In some optional embodiments, the first drive assembly includes a first drive member and a second drive member, the first drive member is transmission-connected to the first working member and is used to drive the first working member to move toward the first end, and the second drive member is transmission-connected to the second working member and is used to drive the second working member to move toward the second end.

[0020] In this way, the first driving member and the second driving member can independently control the first working member and the second working member respectively, so that the assembly device can accurately adjust different parts of the flexible electrical connection structure.

[0021] In some optional embodiments, the first working unit includes a first guide structure and a second guide structure, the first guide structure is fixed relative to the first driving assembly, the second guide structure is arranged on the first working piece, and the first guide structure and the second guide structure are slidably connected along the first direction.

[0022] In this way, the first guide structure and the second guide structure can guide the first workpiece by cooperating with each other, and can ensure that the first workpiece moves accurately along a predetermined path (i.e., the first direction). This helps to avoid unnecessary deviation, thereby improving the position accuracy of the first workpiece during the entire assembly process; in addition, the first guide structure and the second guide structure provide additional support and guidance, making the first workpiece more stable when performing tasks.

[0023] In some optional embodiments, the first working piece includes a first head, and the second working piece includes a second head. The first working unit further includes a third working piece and a fourth working piece, and along the first direction, the third working piece is located on a side of the first head facing away from the second working piece, and the fourth working piece is located on a side of the second head facing away from the first working piece. The third working piece is used to fix the first end to the first circuit board assembly, and the fourth working piece is used to fix the second end to the second circuit board assembly.

[0024] In this way, the third working piece and the fourth working piece can ensure that the first end and the second end of the flexible electrical connection structure are firmly fixed on the corresponding first circuit board assembly and the second circuit board assembly, which is conducive to improving the stability of the assembly, and can also effectively prevent the connection from loosening due to force pulling, etc., reducing the risk of functional failure, thereby enhancing the reliability of the overall equipment.

[0025] In some optional embodiments, the first working unit further includes a first adjusting member, which is connected to the third working member, and when the first adjusting member moves, it can drive the third working member to move along the first direction.

[0026] In this way, the first adjusting member allows the position of the third working member to be dynamically adjusted according to actual assembly requirements, which is conducive to improving the flexibility of the assembly device. In the process of assembling electronic equipment products of different specifications, the first adjusting member can be adjusted to meet specific position requirements.

[0027] In some optional embodiments, the third working member includes a third main body and a third head connected to each other, the third main body is connected to the first adjusting member, the third head is used to be arranged on a side of the third main body facing the flexible electrical connection structure, and an elastic telescopic member is arranged between the third main body and the third head.

[0028] In this way, the elastic telescopic member can provide a buffering effect and can also ensure that the pressure applied by the third head to the flexible electrical connection structure is more uniform.

[0029] In some optional embodiments, the first working piece includes a first part, a second part and a third part connected in sequence, the third part is located on the side of the first part away from the second working piece, the second part is used to connect between an end of the first part away from the flexible electrical connection structure and an end of the third part away from the flexible electrical connection structure, the first part, the second part and the third part enclose an accommodating space; the first driving member is arranged in the accommodating space.

[0030] This is conducive to optimizing the layout of the assembly device and achieving a more compact overall structural layout. This design helps save space. In addition, since the first driving member is directly located inside the first working member it acts on, the driving force can be transmitted to the first working member more directly, reducing energy loss and improving transmission efficiency, and also helping to reduce errors caused by long-distance transmission and improve operating accuracy.

[0031] In some optional embodiments, the assembly device further includes a second driving assembly, and the second driving assembly is used to drive the first working unit to move in a direction toward the flexible electrical connection structure.

[0032] In this way, the second drive component can work in coordination with the first drive component. When adjusting the redundant part of the flexible electrical connection structure, the second drive component can make the first working unit close to the target position, and then the first drive component is responsible for driving the first working unit to achieve the position adjustment of the redundant part. The cooperation between the two can speed up the assembly speed and improve the assembly efficiency.

[0033] In some optional embodiments, the assembly device further includes a third driving assembly and a second working unit, the second working unit is used to be arranged on a side of the flexible electrical connection structure facing away from the front shell, along the first direction, the second working unit is located between the first working piece and the second working piece, and is opposite to the middle part of the flexible electrical connection structure connected between the first end and the second end along the second direction. The third driving assembly is used to drive the second working unit to move in the direction of the flexible electrical connection structure.

[0034] In this way, the third driving component can drive the second working unit to move toward the middle part of the flexible electrical connection structure to adjust the partial redundancy located in the middle part. In this way, the flexible electrical connection structure can be fully redundantly adjusted along the extension direction of the flexible electrical connection structure, which helps to avoid problems caused by excessive or insufficient local redundancy; by adjusting the redundancy of the middle part of the flexible electrical connection structure, its smooth transition and natural bending can be better guaranteed, reducing unnecessary bending or twisting, which can also avoid excessive redundancy in the middle part causing the battery of the electronic device to become warped and loose.

[0035] In some optional embodiments, a storage bin is provided on the inner surface of the front shell, the first circuit board assembly and the second circuit board assembly are located on opposite sides of the storage bin, and part of the flexible electrical connection structure is located in the storage bin. In the direction from the first end to the second end, the length of the storage bin is L1, the dimension of the second working unit along the first direction is L4, and the ratio of L4 to L1 is greater than or equal to 3 / 5 and less than or equal to 4 / 5.

[0036] If the ratio of L4 to L1 is less than 3 / 5, the second working unit and the first working unit may have a poor coordination effect; if the ratio of L4 to L1 is greater than 4 / 5, the first working unit and the second working unit may interfere with each other, collide, etc. By making the ratio of L4 to L1 greater than or equal to 3 / 5 and less than or equal to 4 / 5, the first working unit and the second working unit can form a good coordination effect, so as to achieve effective management of the redundant part of the flexible electrical connection structure.

[0049] Understandably, Figure 1 and Figure 2 The following figures and the related drawings only schematically illustrate some components of the electronic device 200, and the actual shapes, sizes, positions and structures of these components are not subject to the present invention. Figure 1 and Figure 2 and the accompanying drawings below.

[0050] The electronic device 200 is in the shape of a rectangular flat plate. In some other embodiments, the shape of the electronic device 200 may also be a square flat plate, a circular flat plate, an elliptical flat plate, etc.

The screen 30 is used to display images, videos, etc., and a device accommodation space can be formed between the back cover 40 and the front shell 10, for example, for accommodating electronic components such as a camera module, a battery, a speaker module, and a vibration unit.

[0052] The circuit board assembly 20 can be arranged in the device accommodating space. The circuit board assembly 20 includes a first circuit board assembly 201, a second circuit board assembly 202 and a flexible electrical connection structure 203. The flexible electrical connection structure 203 is electrically connected between the first circuit board assembly 201 and the second circuit board assembly 202.

The first circuit board assembly 201 can use a FR-4 dielectric board, a Rogers dielectric board, a mixed dielectric board of FR-4 and Rogers, etc. Here, FR-4 is a code for a flame retardant material grade, and Rogers dielectric board is a high-frequency board.

[0057] The second circuit board assembly 202 is electrically connected to the first circuit board assembly 201 via the flexible electrical connection structure 203 to achieve power and signal connection between the second circuit board assembly 202 and the first circuit board assembly 201, as well as data and signal transmission between the two.

[0058] The battery is located between the first circuit board assembly 201 and the second circuit board assembly 202. The battery is used to provide power to electronic devices in the electronic device 200, such as a display screen, the first circuit board assembly 201, the second circuit board assembly 202, and the like.

[0059] For details, please continue to refer to Figure 2-Figure 3 , the surface of the front shell 10 facing the back cover 40 is the inner surface of the front shell 10, and the first circuit board assembly 201 and the second circuit board assembly 202 are arranged on the inner surface of the front shell 10. The inner surface of the front shell 10 is provided with a storage bin 101, the first circuit board assembly 201 and the second circuit board assembly 202 are arranged at intervals and located on opposite sides of the storage bin 101, a part of the flexible electrical connection structure 203 is located in the storage bin 101, and a part of the flexible electrical connection structure 203 connected to the first circuit board assembly 201 and a part connected to the second circuit board assembly 202 are respectively located on opposite sides of the storage bin 101. The battery is installed in the storage bin 101 and is located on the side of the flexible electrical connection structure 203 away from the front shell 10.

[0060] The flexible electrical connection structure 203 includes a first end 2031, a second end 2032, and a middle portion 2033 connected between the first end 2031 and the second end 2032, wherein the end of the flexible electrical connection structure 203 connected to the first circuit board assembly 201 is the first end 2031, and the end of the flexible electrical connection structure 203 connected to the second circuit board assembly 202 is the second end 2032.

[0061] In some embodiments, see Figure 3The first circuit board assembly 201 and the first end 2031 of the flexible electrical connection structure 203 , as well as the second circuit board assembly 202 and the second end 2032 of the flexible electrical connection structure 203 , can be electrically connected via the connector 204 .

[0063] In order to ensure the connection stability between the flexible electrical connection structure 203 and the first circuit board assembly 201 and between the flexible electrical connection structure 203 and the second circuit board assembly 202, the flexible electrical connection structure 203 is usually designed to have a certain amount of redundancy. It should be noted that the flexible electrical connection structure 203 having redundancy means that when the flexible electrical connection structure 203 is connected to the first circuit board assembly 201 and the second circuit board assembly 202, the actual length of the flexible electrical connection structure 203 is greater than the distance from the first end 2031 to the second end 2032 of the flexible electrical connection structure 203, and a part of the middle part 2033 between the first end 2031 and the second end 2032 is a redundant part.

The tensioned state of the flexible electrical connection structure 203 can be seen in FIG. Figure 3 Shown in the dotted area.

[0064] In the related art, in the process of assembling the front shell 10 and the circuit board assembly 20 of the electronic device 200 by using an automated assembly device, the assembly device directly connects the first end 2031 and the second end 2032 of the flexible electrical connection structure 203 to the first circuit board assembly 201 and the second circuit board assembly 202 respectively by pressing. In this process, due to the neglect of the management effect of the redundant parts, the connection position between the first end 2031 and the first circuit board assembly 201 and the connection position between the second end 2032 and the second circuit board assembly 202 are prone to loosening or connection failure and other poor assembly problems. The redundant parts may even squeeze the battery of the electronic device 200, causing the battery to warp and loosen, thereby reducing the product qualification rate of the electronic device 200.

[0065] Based on this, an embodiment of the present application provides an assembly device that can achieve effective management of the redundant parts of the flexible electrical connection structure 203, so as to ensure the connection stability between the first end 2031 and the first circuit board assembly 201 and the second end 2032 and the second circuit board assembly 202 during the automated assembly process, and to avoid the redundant parts squeezing the battery of the electronic device 200, causing the battery to loosen and warp, etc.

[0066] Next, the structure of the assembly device will be described in detail.

The assembly device 100 may include an assembly mechanism 9, which can be used to assemble the flexible electrical connection structure 203 into the front housing 10 and connect it to the first circuit board assembly 201 and the second circuit board assembly 202.

[0068] It should be noted that Figures 4 to 6 Only partial structures of the assembly device 100 are schematically shown, and the size, shape and number of these structures are not limited to Figures 4 to 6 In some embodiments, the assembly device 100 includes Figure 5 and Figure 6 As shown in the assembly mechanism 9, the assembly device 100 may also include an installation cabinet 6, a mounting frame 7, a material picking mechanism, a detection mechanism, and a supporting mechanism, etc. The mounting frame 7, the material picking mechanism, the detection mechanism, the supporting mechanism, and the assembly mechanism 9 are all arranged in the installation cabinet 6. The installation cabinet 6 can protect the internal structure of the electronic device 200 from dust, moisture and other contaminants during the production process of the electronic device 200.

[0069] The assembly mechanism 9, the material taking mechanism, the detection mechanism and the bearing mechanism can all be fixed to the mounting frame 7, and the mounting frame 7 is used to provide physical support to improve the structural stability and operational stability of the assembly device 100. The detection mechanism is used to detect the components in the material storage area to determine whether they are qualified, and can also be used to detect whether the assembled components meet the assembly requirements. The material taking mechanism is used to transfer the qualified components to be assembled from the material storage area to the bearing mechanism, while the unqualified components will be transferred to the defective area. The bearing mechanism can be used to carry the various components of the electronic device 200, and the assembly mechanism 9 can complete the assembly and connection operations of these components at the bearing mechanism.

[0070] In some optional embodiments, the detection mechanism may be a plurality of charge-coupled devices (CCDs), for example, by taking a photo of the device and inspecting its contour to determine whether it is a qualified product. The material taking mechanism may be a plurality of suction nozzles or grippers.

[0071] Exemplarily, the assembly process of the electronic device 200 may include the following steps: first, the components to be assembled are placed in the storage area of ​​the assembly device 100, the detection mechanism detects the components to confirm whether they are qualified, then the picking mechanism transfers the components to be assembled to the carrying mechanism through a suction nozzle, and then the assembly mechanism 9 completes the assembly operation.

[0072] Please continue reading Figure 5-Figure 6 Combined with Figure 7 , Figure 7 for Figure 5 Schematic diagram of the coordination between the partial structure of the assembly device 100 and the partial structure of the electronic device.

[0073] In some embodiments, the assembly mechanism 9 includes a first working unit 1 and a first driving assembly 2. The first working unit 1 is used to be arranged on the side of the flexible electrical connection structure 203 facing away from the front shell 10. The first working unit 1 includes a first working piece 11 and a second working piece 12 arranged along a first direction (see the direction e1 in the figure), and the first direction is consistent with the direction in which the first end 2031 of the flexible electrical connection structure 203 points to the second end 2032.

[0074] It should be noted that in the description of each embodiment of the present application, "directional consistency" may include absolute consistency and approximate consistency between two directions, where the acceptable deviation range of approximate consistency is, for example, a deviation within 5°, 8° or 10° between the two directions.

[0075] The first driving assembly 2 is transmission-connected to the first working unit 1 , and is used to drive the first working piece 11 and the second working piece 12 to move in directions away from each other, so that the first working piece 11 moves toward the first end 2031 , and the second working piece 12 moves toward the second end 2032 .

[0076] During the operation of the assembly device 100, the first working piece 11 has a first initial position and a first stop position. In the first initial position, the first working piece 11 is opposite to a certain position of the middle portion 2033 of the flexible electrical connection structure 203. During the process in which the first driving component 2 drives the first working piece 11 to move toward the first end 2031, the first working piece 11 moves from the first initial position to the first stop position. During the process in which the first driving component 2 drives the first working piece 11 to move toward the first end 2031, the first working piece 11 can adjust the partial redundancy of the flexible electrical connection structure 203 from the middle portion 2033 gradually toward a position close to the first end 2031.

[0077] The second working piece 12 also has a second initial position and a second stop position. In the second initial position, the second working piece 12 is opposite to a certain position of the middle part 2033 of the flexible electrical connection structure 203. When the first driving component 2 drives the second working piece 12 to move toward the second end 2032, the first working piece 11 moves from the second initial position to the second stop position. When the first driving component 2 drives the second working piece 12 to move toward the second end 2032, the second working piece 12 can gradually adjust the partial redundancy of the flexible electrical connection structure 203 from the middle part 2033 to a position close to the second end 2032.

[0078] In this way, it can be ensured that the flexible electrical connection structure 203 has a certain amount of redundancy at positions close to the first electrical connection component and close to the second electrical connection component, so as to avoid excessive tension of the first end 2031 or the second end 2032 during the assembly process of the electronic device 200 due to the asymmetric distribution of the redundancy of the flexible electrical connection structure 203, resulting in unstable connection with the first circuit board assembly 201 or the second circuit board assembly 202, and avoid the problem of looseness at the connection position, which is beneficial to improve the problem of poor assembly and enhance the connection quality between the circuit board assemblies 20.

[0079] In addition, by adjusting the redundant part of the flexible electrical connection structure 203 toward a position close to the first end 2031 and the second end 2032, it is also possible to avoid excessive redundancy in the middle part 2033 of the flexible electrical connection structure 203, thereby avoiding excessive bending of the flexible electrical connection structure 203 during the subsequent assembly process of the electronic device 200, and avoiding excessive redundant parts squeezing the battery to cause it to warp and loosen, thereby reducing the resulting product failure rate.

[0080] Of course, the first driving assembly 2 can also drive the first working piece 11 to return from the first stop position to the first initial position, and the first driving assembly can also drive the second working piece 12 to return from the second stop position to the second initial position.

[0081] Please continue reading Figure 5-Figure 7In some embodiments, the assembly mechanism 9 may further include a second drive assembly 3 in addition to the above-mentioned first working unit 1 and the first drive assembly 2. The second drive assembly 3 is transmission-connected to the first working unit 1. The second drive assembly 3 is used to drive the first working unit 1 to move in a direction toward the flexible electrical connection structure 203, so as to ensure that the distance between the first working unit 1 and the flexible electrical connection structure 203 and the front shell 10 meets the assembly requirements, so that the first working piece 11 and the second working piece 12 adjust the position of the redundant part of the flexible electrical connection structure 203.

[0082] Of course, the second drive assembly 3 can also drive the first working unit 1 to move in a direction away from the flexible electrical connection structure 203. When the first working piece 11 moves to the first stop position and the second working piece 12 moves to the second stop position, the second drive assembly 3 can drive the first working unit 1 to move in a direction away from the flexible electrical connection structure 203, so that the first drive assembly 2 drives the first working piece 11 to move in a direction away from the first end 2031, and drives the second working piece 12 to move in a direction away from the second end 2032. For the convenience of the following description, the direction of the first working unit 1 toward and away from the flexible electrical connection structure 203 is defined as the second direction (see the direction e2 in the figure).

[0083] In this way, the second drive component 3 can work in coordination with the first drive component 2. When adjusting the redundant part of the flexible electrical connection structure 203, the second drive component 3 can make the first working unit 1 approach the target position, and then the first drive component 2 is responsible for driving the first working unit 1 to achieve the position adjustment of the redundant part. The cooperation between the two can speed up the assembly speed and improve the assembly efficiency.

[0084] In some other embodiments, the assembly device 100 may no longer be provided with the second drive assembly 3, and the bearing mechanism may be provided as a mechanism that can be lifted and lowered along the second direction toward the first working unit 1, so that the distance between the first working unit 1 and the flexible electrical connection structure 203 and the front shell 10 can also be ensured to meet the assembly requirements, and the present application does not impose specific restrictions on this. The embodiment of the present application is a further introduction based on the fact that the assembly device 100 is provided with the second drive assembly 3 to drive the first working unit 1 to move in the direction of the flexible electrical connection structure 203, which cannot be regarded as a special limitation on the present application.

[0085] Please continue reading Figure 5 and Figure 7 In some embodiments, the first driving assembly 2 includes a first driving member 21 and a second driving member 22. The first driving member 21 is transmission-connected to the first working member 11 and is used to drive the first working member 11 to move toward the first end 2031. The second driving member 22 is transmission-connected to the second working member 12 and is used to drive the second working member 12 to move toward the second end 2032.

[0086] In some optional embodiments, the first driving member 21 and the second driving member 22 can both be cylinders. For the convenience of description, the cylinder serving as the first driving member 21 is referred to as the first cylinder, and the cylinder serving as the second driving member 22 is referred to as the second cylinder.

[0087] Please continue reading Figure 5 and Figure 7 In other embodiments, the first working unit 1 further includes a supporting structure 8, and the first driving component 2, the first working piece 11, and the second working piece 12 are all arranged on the supporting structure 8 to improve the installation stability and working reliability of the first driving component 2 and the first working unit 1.

[0088] The cylinder bodies of the first cylinder and the second cylinder are both fixedly connected to the support structure 8, the first working piece 11 is connected to the piston rod of the first cylinder, and the second working piece 12 is connected to the piston of the second cylinder. During the assembly process of the electronic device 200, the piston rod of the first cylinder drives the first working piece 11 to move toward the first end 2031, and the piston rod of the second cylinder drives the second working piece 12 to move toward the second end 2032.

[0089] In this way, the first driving member 21 and the second driving member 22 can independently control the first working member 11 and the second working member 12 respectively, so that the assembly device 100 can accurately adjust different parts of the flexible electrical connection structure 203 .

[0090] In some optional embodiments, the second drive component 3 may also be a cylinder. The cylinder serving as the second drive component 3 is referred to as a third cylinder. The cylinder body of the third cylinder is fixedly connected to the mounting frame 7, and the piston rod of the third cylinder is connected to the support structure 8, so that the second drive component 3 can simultaneously drive the first working piece 11, the second working piece 12 and the first drive component 2 of the first working unit 1 to move toward or away from the flexible electrical connection structure 203.

[0091] The following mainly introduces the internal structure of the first working member 11 and its connection relationship with the support structure 8 and the first driving member 21. The internal structure of the second working member and its connection relationship with the support structure 8 and the second driving member 22 can be the same as the internal structure of the first working member 11 and its connection relationship with the support structure 8 and the first driving member 21, and this application will not go into details.

[0092] In some other embodiments, the internal structure of the second action member and its connection relationship with the support structure 8 and the second drive member 22 may also be different from the internal structure of the first working member 11 and its connection relationship with the support structure 8 and the first drive member 21. This application is exemplified by assuming that the internal structure of the second action member and its connection relationship with the support structure 8 and the second drive member 22 are the same as the internal structure of the first working member 11 and its connection relationship with the support structure 8 and the first drive member 21.

[0093] See also Figure 7 and Figure 8 , Figure 8 for Figure 5 Enlarged view of A in the middle. In some embodiments, the first working member 11 includes a first main body 113 and a first head 114 connected to each other, the first main body 113 is connected to the first driving member 21, the first driving member 21 drives the first main body 113 to move to drive the first head 114 to move toward the first end 2031, and the first head 114 can adjust the partially redundant position of the flexible electrical connection structure 203 from the middle part 2033 to the position close to the first end 2031.

[0094] In some optional embodiments, the first head 114 may gradually change the position of the partial redundancy during the movement of the first head 114 toward the first end 2031 by contacting and applying pressure to the surface of the flexible electrical connection structure 203 facing away from the front shell 10 .

[0095] In some optional embodiments, the first main body 113 and the first head 114 are detachably connected, which facilitates replacement and maintenance of the first head 114 .

[0096] In some optional embodiments, the first main body portion 113 and the first head portion 114 may also be formed as an integrally formed part, which helps to simplify the processing technology.

[0097] In some embodiments, the elastic coefficient of the first head 114 is greater than or equal to the elastic coefficient of the first body 113. Optionally, the first head 114 is made of an elastic material, and the first body 113 is made of a rigid material. For example, the first head 114 is made of an elastic material such as silicone, rubber, etc., and the first body 113 is made of a metal material. Alternatively, both the first head 114 and the first body 113 are made of an elastic material, for example, both the first head 114 and the first body 113 are made of an elastic material such as silicone.

[0098] In this way, the first head 114 has good elasticity, which can prevent the first working piece 11 from causing damage to the flexible electrical connection structure 203 .

[0099] For details, please continue to refer to Figure 7and Figure 8 In some embodiments, the first main body portion 113 includes a first part 1131, a second part 1132 and a third part 1133 connected in sequence, the third part 1133 is located on the side of the first part 1131 away from the second working piece 12, and the second part 1132 is used to connect between an end of the first part 1131 away from the flexible electrical connection structure 203 and an end of the third part 1133 away from the flexible electrical connection structure 203.

[0100] The first head 114 is connected to one end of the first portion 1131 facing the flexible electrical connection structure 203 , so that the first head 114 is farther away from the first end 2031 of the flexible electrical connection structure 203 , which is beneficial to increase the movement space of the first head 114 .

[0101] In some embodiments, the first portion 1131, the second portion 1132, and the third portion 1133 enclose an accommodating space 1134, and the first driving member 21 is disposed in the accommodating space 1134. Exemplarily, the first driving member 21 is connected to a side of the third portion 1133 facing the first portion 1131, for example, the first driving member 21 is a first cylinder, and a piston rod of the first cylinder is connected to a side of the third portion 1133 facing the first portion 1131.

[0102] In this way, it is helpful to optimize the layout of the assembly device 100 and realize a more compact overall structural layout. This design helps to save space. In addition, since the first driving member 21 is directly located inside the first working member 11 on which it acts, the driving force can be transmitted to the first working member 11 more directly, reducing energy loss and improving transmission efficiency, and also helping to reduce errors caused by long-distance transmission and improve operating accuracy.

[0103] Please continue reading Figure 8 In some optional embodiments, the first working piece 11 may include a third adjusting piece 19, which is connected to the first head 114 and can adjust the distance between the first head 114 and the flexible electrical connection structure 203 along the second direction. This is conducive to further accurately controlling the adjustment effect of the first working piece 11 on the flexible electrical connection structure 203.

[0104] Please continue reading Figure 8In some embodiments, the end of the first working piece 11 facing the flexible electrical connection structure 203 is the third end 111, the end of the first working piece 11 facing away from the flexible electrical connection structure 203 is the fourth end 112, the third end 111 includes a first side surface 1111 and a second side surface 1112, the first side surface 1111 faces the second working piece 12, the second side surface 1112 faces away from the second working piece 12, and the distance from the first side surface 1111 to the second side surface 1112 gradually decreases along the direction from the fourth end 112 to the third end 111. The direction from the third end 111 to the third end 111 is consistent with the second direction.

[0105] In this way, the first working piece 11 can have more movement space without increasing the size of the overall device, and the travel range of the first working piece 11 along the first direction is expanded, which is conducive to increasing the adjustment range when the first working piece 11 adjusts the redundant part of the flexible electrical connection structure 203. In addition, it is also helpful to optimize the matching relationship between the first working piece 11 and the flexible electrical connection structure 203, for example, it is helpful to optimize the contact angle and pressure.

[0106] Please continue reading Figure 8 In some embodiments, the first side surface 1111 and the second side surface 1112 are located at the first head 114. In this way, the movement space of the first head 114 can be further increased, which is conducive to improving the adjustment effect of the first working piece 11 on the redundant part of the flexible electrical connection structure 203.

[0107] Please continue reading Figure 8 In some embodiments, along the direction from the fourth end 112 to the third end 111, the first side surface 1111 extends obliquely in a direction away from the second working piece 12. In this way, the interference between the first working piece 11 and surrounding components can be reduced, which is conducive to improving the operational flexibility of the first working piece 11.

[0108] On this basis, in other embodiments, along the direction from the fourth end 112 to the third end 111, the second side surface 1112 may also be inclined toward the direction close to the second working piece 12; or the second side surface 1112 may be formed as a plane extending along the direction from the fourth end 112 to the third end 111.

[0109] Please continue reading Figure 7 and Figure 8 In some embodiments, the second side surface 1112 is used to adapt to the inner side surface of the accommodating compartment 101 adjacent to the first circuit board assembly 201 .

[0110] Exemplarily, the inner side surface of the accommodating chamber 101 adjacent to the first circuit board assembly 201 is formed as a plane, and the second side surface 1112 can be formed as a plane that matches the inner side surface of the accommodating chamber 101 adjacent to the first circuit board assembly 201 .

[0111] Exemplarily, the inner side surface of the accommodating chamber 101 adjacent to the first circuit board assembly 201 is formed as a curved surface, and the second side surface 1112 can be formed as a curved surface that matches the inner side surface of the accommodating chamber 101 adjacent to the first circuit board assembly 201 .

[0112] In the process of the first driving member 21 driving the first working member 11 to move toward the first end 2031, when the first working member 11 moves to a position where the second side surface 1112 contacts the inner side surface of the accommodating bin 101 adjacent to the first circuit board assembly 201, the first working member 11 reaches the first stop position and the first driving member 21 stops driving.

[0113] In this way, during the movement of the first working piece 11 toward the first end 2031, the assembly device 100 can control the position of the first working piece 11 by means of the matching relationship between the second side surface 1112 and the inner side surface of the accommodating bin 101 that matches it, so as to achieve accurate control of the travel range of the first working piece 11, thereby facilitating the control of the adjustment range of the redundant part of the flexible electrical connection structure 203.

[0114] In some optional embodiments, a cylinder with a corresponding stroke can be configured as the first driving member 21 based on the travel distance from the first initial position of the first working member 11 to the first stop position where the second side surface 1112 and the inner side surface of the accommodating bin 101 adjacent to the first circuit board assembly 201 are in contact.

[0115] In some embodiments, the first head 114 further has a curved surface 1113 on a side facing away from the second working piece 12, and the curved surface 1113 is connected to one end of the second side surface 1112 facing the fourth end 112. The end of the curved surface 1113 connected to the second side surface 1112 is closer to the third end 111 than the end of the curved surface 1113 away from the second side surface 1112, and the curved surface 1113 is formed to be concave in a direction away from the third end 111. In this way, when the first head 114 moves to a position matching the inner side surface of the accommodating bin 101, the curved surface 1113 can be used to avoid devices near the accommodating bin 101 to avoid interference or damage to them.

[0116] See also Figure 9-10 , Fig. 9 for Figure 5 A front view of a partial structure of the assembly device 100; Fig.10 for Fig. 9In some embodiments, the first working unit 1 further includes a first guide structure 13 and a second guide structure 14, the first guide structure 13 is fixed relative to the first driving member 21, the second guide structure 14 is disposed on the first working member 11, and the first guide structure 13 and the second guide structure 14 are slidably connected along the first direction.

[0117] The first guide structure 13 is fixedly connected to the support structure 8, that is, the first working piece 11 is indirectly connected to the support structure 8 through the first guide structure 13 and the second guide structure 14. The first guide structure 13 and the first driving assembly 2 are fixed in relative position, so that when the first driving assembly 2 drives the first working piece 11 to move, the first working piece 11 can drive the second guide structure 14 to slide relative to the first guide structure 13, so that the first working piece 11 can accurately move toward the first end 2031.

[0118] In this way, the first guide structure 13 and the second guide structure 14 can guide the first working piece 11 by cooperating with each other, and can ensure that the first working piece 11 moves accurately along a predetermined path. This helps to avoid unnecessary deviation, thereby improving the position accuracy of the first working piece 11 during the entire assembly process; in addition, the first guide structure 13 and the second guide structure 14 provide additional support and guidance, making the first working piece 11 more stable when performing tasks.

[0119] Please continue reading Figure 9-10 Combined with Figure 7 In some optional embodiments, the support structure 8 includes a first support plate 81 and a first support block 82 arranged on the first support plate 81. The extension direction of the first support plate 81 is the second direction. For the convenience of subsequent description, the thickness direction of the first support plate 81 is defined as a third direction (see the e3 direction in the figure). The first direction, the second direction and the third direction intersect with each other.

[0120] The first support block 82 is used to be arranged on one side of the first support plate 81 along the thickness direction thereof facing the front housing 10, and the first support block 82 is located in the accommodation space 1134 of the first working piece 11. Along the second direction, the first support block 82 and the second portion 1132 of the first working piece 11 are arranged opposite to each other and spaced apart.

[0121] Please continue reading Fig.10In some optional embodiments, along the second direction, the first guide structure 13 is provided on the end surface of the first support block 82 facing the second part 1132, and the second guide structure 14 is provided on the surface of the second part 1132 facing the first support block 82. Exemplarily, the first guide structure 13 is a slide rail, and the second guide structure 14 is a slider, and the slider is slidably connected to the slide rail. Specifically, the slide rail can be a riding slide rail, having a first slide groove and a second slide groove arranged oppositely, and the slider has a first sliding part and a second sliding part arranged oppositely, and the first sliding part and the second sliding part are correspondingly accommodated in the first slide groove and the second slide groove.

[0122] Of course, in some other optional embodiments, the slide rail may also be a groove type slide rail.

[0123] In some optional embodiments, the first guide structure 13 is detachably connected to the first support block 82 , and the second guide structure 14 is detachably connected to the second portion 1132 of the first working piece 11 .

[0124] Please continue reading Figure 9-10 In some optional embodiments, the first driving member 21 is fixedly connected to the first support plate 81, and along the third direction, the first driving member 21 and the first support block 82 are located on the same side. Along the second direction, the first support block 82 and the first driving member 21 are staggered, so that the space requirement of the first support block 82 and the first driving member 21 in the first direction can be reduced. For example, the first driving member 21 is located on the side of the first support block 82 away from the second portion 1132 along the second direction.

[0125] Of course, in other embodiments, the first working unit 1 may also include a third guide structure and a fourth guide structure. The relationship between the third guide structure and the fourth guide structure and the second working piece 12 and the guiding principle thereof are the same as the relationship between the first guide structure 13 and the second guide structure 14 and the first working piece 11 and the guiding principle thereof, and the embodiments of the present application will not elaborate on this.

[0126] See also Figure 7-Figure 10 In some embodiments, the first working unit 1 further includes a third working piece 15 , which is located on a side of the first head 114 facing away from the second working piece 12 along the first direction, and is used to fix the first end 2031 to the first circuit board assembly 201 .

[0127] The second working piece 12 includes a second main body and a second head portion disposed on the second main body. The first working unit 1 also includes a fourth working piece 16, which is located on a side of the second head portion facing away from the first working piece 11 along the first direction, and is used to fix the second end 2032 to the second circuit board assembly 202.

[0128] It should be noted that in the embodiment of the present application, “fixed on” can be understood as ensuring a stable and reliable electrical and mechanical connection between the first end 2031 of the flexible electrical connection structure 203 and the first circuit board assembly 201 or the second end 2032 and the second circuit board assembly 202 in some way.

[0129] In some optional embodiments, during the process of the second driving component 3 driving the first working unit 1 to move toward the flexible electrical connection structure 203, the third working piece 15 fixes the first end 2031 to the first circuit board assembly 201 by pressing, and the fourth working piece 16 fixes the second end 2032 to the second circuit board assembly 202 by pressing; or, the third working piece 15 fixes the first end 2031 to the first circuit board assembly 201 by clamping, and the fourth working piece 16 fixes the second end 2032 to the second circuit board assembly 202 by clamping.

[0130] Exemplarily, the first end 2031 of the flexible electrical connection structure 203 is connected to the first circuit board assembly 201 through the board-to-board connector 204, and the second end 2032 is connected to the second circuit board assembly 202 through the board-to-board connector 204. In the process of the second driving component 3 driving the first working unit 1 to move toward the flexible electrical connection structure 203, the third working piece 15 and the fourth working piece 16 press the board-to-board connector 204 so that the first end 2031 is fixed to the first circuit board assembly 201 and the second end 2032 is fixed to the second circuit board assembly 202. The pressure applied by the third working piece 15 and the fourth working piece 16 to the board-to-board connector 204 should generally be less than 65N to avoid unnecessary damage to it.

[0131] In this way, the third working piece 15 and the fourth working piece 16 can ensure that the first end 2031 and the second end 2032 of the flexible electrical connection structure 203 are firmly fixed to the corresponding first circuit board assembly 201 and the second circuit board assembly 202, which is conducive to improving the stability of the assembly, and can also effectively prevent the connection from being loosened due to force pulling, etc., reducing the risk of functional failure, thereby enhancing the reliability of the overall device. For example, this can prevent the first working piece 11 and the second working piece 12 from pulling the first end 2031 and the second end 2032 when adjusting the redundant part on the flexible electrical connection structure 203, thereby preventing the connection from being loosened.

[0132] In some optional embodiments, the third working piece 15 is disposed in the accommodating space 1134 of the first working piece 11, and the third working piece 15 can be movably connected to the first supporting block 82, so that the third working piece 15 can make full use of the space inside the accommodating space 1134, so that the first working unit 1 has a compact structure, and this makes it convenient for the distance between the third working piece 15 and the first head 114 to meet the production requirements of the electronic device 200.

[0133] Please continue reading Fig.10 In some embodiments, the first working unit 1 further includes a first adjusting member 17, and the first adjusting member 17 is connected to the third working member 15. When the first adjusting member 17 moves, it can drive the third working member 15 to move along the first direction.

[0134] Specifically, the first adjusting member 17 is connected between the first support block 82 and the third working member 15, and when the first adjusting member 17 moves, it can drive the third working member 15 to move relative to the first support block 82 along the first direction. Of course, the first adjusting member 17 may not be connected to the first support block 82, and the third working member 15 may be movably connected to the first support block 82 through the remaining connecting members, so that under the driving action of the first adjusting member 17, the third working member 15 can be movable relative to the first working member 11, and the spacing between the first working member 11 and the third working member 15 along the first direction can be adjusted. The embodiment of the present application is introduced on the basis that the third working member 15 is movably connected to the first support block 82 through the first adjusting member 17, but this does not constitute a specific limitation of the present application.

[0135] Exemplarily, the first adjusting member 17 is an adjusting screw. When the first adjusting member 17 rotates, it can drive the third working member 15 to move along the first direction toward or away from the first working member 11 .

[0136] Thus, the first adjusting member 17 allows the position of the third working member 15 along the first direction to be dynamically adjusted according to actual assembly requirements, which is beneficial to improving the flexibility of the assembly device 100. During the assembly of electronic devices 200 of different specifications, the first adjusting member 17 can be adjusted to meet specific position requirements.

[0137] Please continue reading Fig.10 In some embodiments, the third working member 15 includes a third main body 151 and a third head 152 connected to each other. The third main body 151 is connected to the first adjusting member 17. The third main body 151 is connected to the first supporting block 82 through the first adjusting member 17. The third head 152 is located on the side of the first supporting member facing away from the first guide structure 13.

[0138] In some optional embodiments, the third head 152 is detachably connected to the third body 151. Exemplarily, the third head 152 is provided with a first connection hole, the third body 151 is provided with a second connection hole, and the connecting member is passed through the first connection hole and connected to the second connection hole.

[0139] The third head 152 is used to be arranged on a side of the third body 151 facing the flexible electrical connection structure 203, and an elastic expansion member 153 is arranged between the third body 151 and the third head 152. Exemplarily, the elastic expansion member 153 is sleeved on the outer peripheral side of the connector.

[0140] In this way, the elastic stretch member 153 can provide a buffering effect and can also ensure that the pressure applied by the third head 152 to the flexible electrical connection structure 203 is more uniform.

[0141] In some optional embodiments, along the second direction, there is a height difference between the end surface of the third head 152 facing the flexible electrical connection structure 203 and the end surface of the first head 114 facing the flexible electrical connection structure 203, and the height difference value can be determined according to the depth of the accommodating chamber 101 of the electronic device 200 and the height of the connecting component between the first end 2031 and the first circuit board assembly 201. For example, the first end 2031 and the first circuit board assembly 201 are connected through a board-to-board connector, and the height difference value needs to meet the requirements of the depth of the accommodating chamber 101 and the height of the board-to-board connector.

[0142] Please continue reading Fig.10 In some optional embodiments, the third working piece 15 may further include a second adjusting piece 18, which is connected between the third main body 151 and the third head 152. When the third working piece 15 moves, it can drive the third head 152 to move in a direction close to the flexible electrical connection structure 203, so that the distance between the third head 152 and the flexible electrical connection structure 203 along the second direction can be adjusted.

[0143] The internal structure of the fourth working piece 16 and its connection relationship with the second working piece 12 are the same as the internal structure of the third working piece 15 and its connection relationship with the first working piece 11 , and will not be described in detail in this application.

[0144] Please return to Figure 5-Figure 7 In some embodiments, the assembly device 100 further includes a third driving assembly 5 and a second working unit 4. The second working unit 4 is used to be arranged on a side of the flexible electrical connection structure 203 that is away from the front housing 10. Along the first direction, the second working unit 4 is located between the first working piece 11 and the second working piece 12, and is opposite to the middle portion 2033 of the flexible electrical connection structure 203 connected between the first end 2031 and the second end 2032 along the second direction. The third driving assembly 5 is transmission-connected to the second working unit 4. The third driving assembly 5 is used to drive the second working unit 4 to move toward the direction of the flexible electrical connection structure 203. The third driving assembly 5 can drive the second working unit 4 to move toward the middle portion 2033 of the flexible electrical connection structure 203 to adjust the partial redundancy located in the middle portion 2033.

[0145] In some optional embodiments, the second working unit 4 adjusts the position of the partial redundancy located in the middle portion 2033 by pressing the middle portion 2033 of the flexible electrical connection structure 203 .

[0146] In some optional embodiments, the third driving component 5 can be a cylinder, and the cylinder serving as the third driving component 5 is called a fourth cylinder. The cylinder body of the fourth cylinder is fixedly connected to the mounting frame 7, and the piston rod of the fourth cylinder is connected to the second working unit 4 to drive the second working unit 4 to move toward or away from the flexible electrical connection structure 203.

[0147] In this way, through the cooperation of the first working unit 1 and the second working unit 4, the flexible electrical connection structure 203 can be fully redundantly adjusted along the extension direction of the flexible electrical connection structure 203, which helps to avoid problems caused by excessive or insufficient local redundancy; by adjusting the redundancy of the middle part 2033 of the flexible electrical connection structure 203, its smooth transition and natural bending can be better guaranteed, and unnecessary bending or twisting can be reduced. This can also avoid the excessive redundancy of the middle part 2033 causing the battery of the electronic device 200 to become warped and loose.

[0148] Of course, the third driving assembly 5 can also be used to drive the second working unit 4 to move in a direction away from the flexible electrical connection structure 203 .

[0149] In order to ensure the effective adjustment of the redundant part of the flexible electrical connection structure 203 by the first working unit 1 and to avoid interference between the first working unit 1 and other components during movement, it is necessary to control the travel distance of the first working piece 11 toward the first end 2031 and the travel distance of the second working piece 12 toward the second end 2032.

[0150] Please continue reading Figure 7 In some embodiments, along the direction from the first end 2031 to the second end 2032, the size of the accommodating chamber 101 is L1. The travel of the first working member 11 toward the first end 2031 is L2, that is, the distance between the first initial position and the first stop position of the first working member 11 is L2. The travel of the second working member 12 toward the second end 2032 is L3, that is, the distance between the second initial position and the second stop position of the second working member 12 is L3. The ratio of L2 to L1 and the ratio of L3 to L1 are both greater than or equal to 1 / 5 and less than or equal to 2 / 5.

[0151] If the ratio of L2 to L1 and the ratio of L3 to L1 are less than 1 / 5, the travel range of the first working piece 11 and the second working piece 12 is limited, resulting in limited adjustment effect on the flexible electrical connection structure 203, which may not meet the assembly requirements; if the ratio of L2 to L1 and the ratio of L3 to L1 are greater than 2 / 5, the travel range of the first working piece 11 is large, which will have higher requirements on the first driving member 21 that drives the first working piece 11 and the second working piece 12 to move. When the ratio of L2 to L1 and the ratio of L3 to L1 are both greater than or equal to 1 / 5 and less than or equal to 2 / 5, within this range, the first working piece 11 and the second working piece 12 can achieve effective adjustment of the flexible electrical connection structure 203, and at the same time will not have high requirements on the first driving member 21, which is conducive to cost saving.

[0152] In order to achieve effective cooperation between the first working unit 1 and the second working unit 4 and avoid interference or collision between the two, in some embodiments, the size of the second working unit 4 along the first direction is L4, and the ratio of L4 to L1 is greater than or equal to 3 / 5 and less than or equal to 4 / 5.

[0153] If the ratio of L4 to L1 is less than 3 / 5, the second working unit 4 and the first working unit 1 may have a poor matching effect; if the ratio of L4 to L1 is greater than 4 / 5, the first working unit 1 and the second working unit 4 may interfere with each other, collide, etc. By making the ratio of L4 to L1 greater than or equal to 3 / 5 and less than or equal to 4 / 5, the first working unit 1 and the second working unit 4 can form a good matching effect, so as to achieve effective management of the redundant part of the flexible electrical connection structure 203.
