Description

[0001] This application is a divisional application. The original application has the application number 202311713827.2 and the original application date is December 13, 2023. The entire contents of the original application are incorporated herein by reference. Technical Field

[0002] This application relates to the field of electronic technology, and more particularly to an electronic device. Background Technology

[0003] In recent years, mobile phones, tablets, and other electronic devices have become increasingly common in people's lives. Screen-to-body ratio (SRR) is the ratio of the display area of ​​an electronic device's screen to the area of ​​its front panel. With the same front panel area, a higher SRR results in a larger display area and a better user experience. To provide users with a better experience, manufacturers have made many efforts to increase the SRR. For example, most mobile phones have now eliminated the Home (navigation) button at the bottom of the screen to improve the SRR. While this has had some effect, the SRR is still relatively limited, and the user experience still needs further improvement. Summary of the Invention

[0004] This application provides an electronic device that can improve the problem of limited screen ratio in existing electronic devices.

[0005] This application provides an electronic device including a display module, a transparent cover, a mid-frame, and a first connector. The transparent cover is fixed to the light-emitting surface of the display module. The display module includes a display unit and a flexible circuit board. One end of the display unit is a wire-emitting end, and one end of the flexible circuit board is connected to the wire-emitting end. The other end of the flexible circuit board is located on the side of the display unit opposite to the transparent cover and extends in a direction pointing towards the center of the display unit. The first connector is located on the side of the transparent cover facing the display module. The first connector includes a first connecting portion and a second connecting portion. The first connecting portion embeds the portion of the flexible circuit board located at the wire-emitting end into the first connecting portion. The second connecting portion covers the side of the display module except for the side connected to the first connecting portion. The second connecting portion is connected end-to-end to the first connecting portion, and the thickness of the second connecting portion is less than or equal to the thickness of the first connecting portion. The orthographic projection of the first connector on the plane of the transparent cover is located on the transparent cover. The mid-frame includes a middle plate and a frame. The middle plate is located within the area enclosed by the frame and is fixedly connected to the frame. The surface of the first connector opposite to the display module is fixedly connected to the middle plate, and there is a gap between the edge of the transparent cover and the frame. In this solution, the first connector covers the entire outer periphery of the display module. This first connector protects the display module during assembly and in situations such as drops, preventing collisions between the display module and the mid-frame. Therefore, there is no need for a clearance gap between the display module and the mid-frame. Furthermore, the first connector is fixedly connected to the opposite surface of the display module and the mid-plate. By eliminating the clearance gap between the display module and the frame, under the same conditions, compared to other electronic devices, the electronic device provided in this application can achieve a larger display area and a smaller black border, resulting in a higher screen-to-body ratio.

[0006] In one possible embodiment, the second connecting portion includes a first sub-connecting portion and two second sub-connecting portions. The first sub-connecting portion is opposite to the first connecting portion, and the two second sub-connecting portions are connected between the first sub-connecting portion and the first connecting portion. The thickness of the first sub-connecting portion is less than the thickness of the first connecting portion, or the thickness of the section of the second sub-connecting portion away from the first connecting portion is less than the thickness of the first connecting portion. The end of the electronic device away from the first connecting portion typically needs to stack components such as the motherboard, front-facing camera, and earpiece, resulting in more limited space. Therefore, making the thickness of the second connecting portion smaller in the corresponding area is beneficial for fully utilizing the overall space and for controlling the overall thickness of the electronic device.

[0007] In one possible embodiment of the aforementioned second sub-connecting portion, the second sub-connecting portion includes a first segment and a second segment located on the side opposite to the first segment and the first connecting portion. The thickness of the first segment is greater than the thickness of the second segment. The thickness gradually decreases at the end where the first segment and the second segment connect, or the connection between the first segment and the second segment is stepped.

[0008] In one possible embodiment, the first connecting portion includes a screen connecting portion and a mid-frame connecting portion. The screen connecting portion embeds the portion of the flexible circuit board located at the outgoing end within the screen connecting portion, and the mid-frame connecting portion is fixedly connected to the side of the screen connecting portion opposite to the transparent cover plate. The mid-plate is provided with a first limiting portion, and the mid-frame connecting portion is fixedly connected to the first limiting portion. Thus, through the cooperation of the mid-frame connecting portion and the first limiting portion, the connection between the first connecting portion and the mid-plate is strengthened, making the connection between the first connecting portion and the mid-plate more reliable. This further mitigates the impact between the display module and the mid-frame during drops, better protecting the display module.

[0009] In one possible embodiment, one of the middle frame connecting portion and the first limiting portion includes a mounting groove, and the other includes a boss, which is inserted into the mounting groove and fixedly connected to the mounting groove.

[0010] Furthermore, in one possible embodiment, the mid-frame connecting portion includes a boss, and the first limiting portion includes a mounting groove. The dimension of the end of the boss near the screen connecting portion is greater than or equal to the dimension of the end of the boss away from the screen connecting portion. In another possible embodiment, the mid-frame connecting portion includes a mounting groove, and the first limiting portion includes a boss. The dimension of the end of the boss near the screen connecting portion is less than or equal to the dimension of the end of the boss away from the screen connecting portion. In both of the above solutions, when all other connections between the first connector and the mid-frame are released, that is, when the only remaining connection between the first connector and the mid-frame is the connection between the mounting groove and the boss, the first connector can be pulled out from the mid-plate without damaging the first connector and the mid-plate, making it easier to maintain the electronic device.

[0011] In one possible embodiment, the surface of the mounting groove for connecting with the first connecting part is provided with an adhesive layer, and the boss is bonded to the mounting groove through the adhesive layer.

[0012] In one possible embodiment, the first connecting part and the second connecting part are integrally molded plastic components. In this way, on the one hand, the steps of connecting the first connecting part and the second connecting part are reduced, which simplifies the assembly process; on the other hand, the circumferential sealing performance of the first connecting part is better guaranteed, which is more conducive to the waterproofing of electronic devices.

[0013] In one possible embodiment, the mid-frame includes a first sidewall for connecting to the first connecting portion, the first sidewall having a receiving groove with its opening facing the display module. The electronic device also includes a limiting member. The limiting member is fixed in the receiving groove and abuts against the first connecting portion to strengthen the connection between the first connecting portion and the frame, further mitigating the impact between the display module and the mid-frame during a drop.

[0014] In one possible embodiment, the limiting member includes a limiting strip made of soft rubber with a Shore hardness of 20-50 HA.

[0015] Another electronic device provided in this application includes a display module, a transparent cover, a mid-frame, and a second connector. The transparent cover is fixed to the light-emitting surface of the display module. The display module includes a display unit and a flexible circuit board. One end of the display unit is a wire-emitting end, and one end of the flexible circuit board is connected to the wire-emitting end. The other end of the flexible circuit board is located on the side of the display unit opposite to the transparent cover and extends towards the center of the display unit. The second connector is located on the side of the transparent cover facing the display module. The second connector includes a third connecting part and a fourth connecting part. The third connecting part embeds the portion of the flexible circuit board located at the wire-emitting end within the third connecting part. The fourth connecting part is fixedly connected to the side of the third connecting part opposite to the transparent cover. The orthographic projections of the display module and the second connector onto the plane of the transparent cover are both located on the transparent cover. The mid-frame includes a middle plate and a frame. The middle plate is located within the area enclosed by the frame, and the middle plate is fixedly connected to the frame. The middle plate has a second limiting part corresponding to the fourth connecting part. The fourth connecting part is fixedly connected to the second limiting part. There is a gap between the edge of the transparent cover and the frame. In this solution, the third connecting part embeds the portion of the flexible circuit board located at the cable exit end. This third connecting part protects the cable exit end of the display module during assembly and in situations such as drops, preventing it from colliding with the mid-frame. Therefore, there is no need to provide a clearance gap between the cable exit end of the display module and the mid-frame. Simultaneously, it is fixedly connected to the second limiting part on the mid-plate via the fourth connecting part. By eliminating the clearance gap between the display module and the frame, under the same conditions, compared to other electronic devices, the electronic device provided in this application can achieve a larger display area for the display unit and a smaller black border ratio for the display module, resulting in a larger screen-to-body ratio.

[0016] Another electronic device provided in this application includes a display module, a transparent cover, and a middle frame. The middle frame includes a middle plate and a frame, with the middle plate located within the area enclosed by the frame and fixedly connected to the frame. The display module is disposed on the middle plate, and the transparent cover is fixed to the light-emitting surface of the display module, with the edge of the transparent cover extending beyond the edge of the display module. A support portion is provided on the surface of the transparent cover facing the display module. The display module includes a display unit and a flexible circuit board. One end of the display unit is a wire-emitting end. The flexible circuit board includes a first end, a second end, and a connecting segment. The first end is connected to the wire-emitting end, and the second end is located on the side of the display unit opposite to the transparent cover and extends in a direction pointing towards the center of the display unit. The connecting segment is located between the display unit and the frame, and connects the first end and the second end. The support portion abuts against the connecting segment, and the distance between the connecting segment and the transparent cover gradually increases along the direction from the wire-emitting end towards the frame and the portion adjacent to the wire-emitting end. The orthographic projection of the support portion on the middle plate is within the range of the orthographic projection of the connecting segment on the middle plate. In this solution, the connecting segment of the flexible circuit board is tilted towards the direction of the middle plate under the action of the support. Compared with the case where the connecting segment is set horizontally in the related technology, the size of the connecting segment in the black border width direction is smaller. As a result, the electronic device provided by this solution has a smaller black border width of the display module and a larger display area of ​​the display module compared with the electronic devices in the related technology. The black border ratio of the display module is smaller, which means that the screen ratio of the electronic device is larger. Attached Figure Description

Detailed Implementation

[0018] Electronic devices, such as mobile phones, tablets, laptops, and watches, typically include components such as a display screen and a 3" mid-frame. The display screen is mounted on the 3" mid-frame and is used to display images. It is well known that the screen-to-body ratio of electronic devices directly affects the user experience; all other things being equal, a higher screen-to-body ratio results in a better user experience. Therefore, improving the screen-to-body ratio has always been a focus in the electronic device industry, and manufacturers have been continuously refining their efforts in this area. Figure 1 This is a partial cross-sectional view of an electronic device in one embodiment, such as... Figure 1 As shown, the electronic device includes a display screen and a mid-frame 3". The display screen includes a display module 1 and a transparent cover 2. The mid-frame 3 has a stepped structure. The transparent cover 2 is fixed to the light-emitting surface of the display module 1, and its edge extends beyond the edge of the display module 1. The transparent cover 2 is fixed to the stepped surface of the mid-frame 3 by an adhesive layer 7. To prevent damage to the display module 1 during assembly due to collisions, a clearance gap is provided between the display module 1 and the mid-frame 3. Let A be the width of the black border of the display module 1 itself, B be the clearance gap between the display module 1 and the mid-frame 3 in the same direction, and C be the dimension of the stepped surface. Then, the black border width of the electronic device is A+B+C. B is typically greater than or equal to 0.3 mm, and C is typically greater than or equal to 0.5 mm. In other words, the black border width of the electronic device is greater than or equal to A+0.8 mm. The black border width of the electronic device is still relatively large, the screen-to-body ratio is still relatively high, and the user experience still needs improvement.

[0019] Based on this, embodiments of this application provide an electronic device to solve the aforementioned problems. To make the objectives, technical solutions, and advantages of this application clearer, the application will be described in further detail below with reference to the accompanying drawings. It is worth noting that the width of the black border mentioned in this embodiment refers to the size of the black border in the direction from the center of the display module to the corresponding black border.

[0021] References to "one embodiment" or "some embodiments" as described in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized.

[0022] Figure 2 This is a front view of an electronic device provided in an embodiment of this application. Figure 3 for Figure 2 The DD cross-sectional view of the electronic device shown. Figure 4 for Figure 2 The EE cross-sectional view of the electronic device shown. Figures 2-4As shown in the figure, an electronic device provided in this application includes a display module 1, a transparent cover plate 2, a middle frame 3, and a first connector 4. The transparent cover plate 2 is fixed to the light-emitting surface of the display module 1 to protect the display module 1. The display module 1 includes a display unit 11 and a flexible printed circuit board 12 (FPC). One end of the display unit 11 is a wire-out end, which is connected to the circuit board through the flexible circuit board 12, thereby enabling the display unit 11 to perform a display function. Specifically, one end of the flexible circuit board 12 is connected to the wire-out end, and the other end of the flexible circuit board 12 is located on the side of the display unit 11 opposite to the transparent cover plate 2 and extends in a direction pointing towards the center of the display unit 11. That is, after the flexible circuit board 12 is connected to the wire-out end of the display module 1, it first extends in a direction opposite to the display unit 11, and then bends towards the side where the display unit 11 is located, opposite to the light-emitting surface of the display module 1. The portion of the flexible circuit board 12 at the wire-out end has a U-shaped structure with an opening facing the side where the display unit 11 is located. The first connector 4 is located on the side of the transparent cover plate 2 facing the display module 1. The first connector 4 includes a first connecting portion 41 and a second connecting portion 42. The first connecting portion 41 embeds the portion of the flexible circuit board 12 at the outgoing end, that is, the U-shaped structure of the flexible circuit board 12, into the first connecting portion 41 to protect the bent portion of the flexible circuit board 12 and prevent the bent portion of the flexible circuit board 12 from being damaged by collision with the middle frame 3 during the installation of the display module 1 onto the middle frame 3. The second connecting portion 42 covers the side of the display module 1 except for the side connected by the first connecting portion 41, and the second connecting portion 42 is connected end to end with the first connecting portion 41, so that the first connecting portion 41 and the second connecting portion 42 together form a closed-loop structure covering the entire circumference of the display module 1. Furthermore, the thickness of the second connecting portion 42 is less than or equal to the thickness of the first connecting portion 41. The orthographic projection of the first connector 4 on the plane of the transparent cover plate 2 is located on the transparent cover plate 2, that is, the first connector 4 does not extend beyond the edge of the transparent cover plate 2. The middle frame 3 includes a middle plate 31 and a frame 32. The middle plate 31 is located within the area enclosed by the frame 32, and the middle plate 31 is fixedly connected to the frame 32. The surface of the first connector 4 opposite to the display module 1 is fixed to the middle plate 31, and the surface of the first connector 4 opposite to the display module 1 is sealed with the middle plate 31, thereby achieving a waterproof seal between the display module 1 and the middle frame 3 while fixing the transparent cover 2 and the display module 1 to the middle frame 3. It is worth noting that in this embodiment, there is a gap between the edge of the transparent cover 2 and the frame 32, that is, the frame 32 does not have a gap similar to the one in the middle frame 3. Figure 1 The stepped surface used to bond the transparent cover plate 2 in the electronic device shown.

[0023] In this design, the first connector 4 covers the entire outer periphery of the display module 1. The first connector 4 protects the display module 1 during assembly and in situations such as drops, preventing collisions between the display module 1 and the mid-frame 3. Therefore, there is no need to provide a clearance gap between the display module 1 and the mid-frame 3. Furthermore, the first connector 4 is fixedly connected to the opposite surface of the display module 1 and the mid-plate 31. Compared to... Figure 1 The electronic device shown eliminates the clearance between the display module 1 and the frame 32; therefore, under the same conditions, compared to Figure 1 The electronic device shown in this embodiment allows for a larger display area of ​​the display unit 11 and a smaller black border width, resulting in a larger screen-to-body ratio. Specifically, let A' be the black border size of the display module 1 on the side where the output cable is located, and C be the size of the first connecting portion 41 in the same direction. 1 The first connecting part 41 extends beyond the size of the flexible circuit board by C. 11 Under the same conditions, that is, when the shape and area of ​​the display modules are the same, and the width of the black borders of the display modules other than the end where the cable exits is located are the same and are all on the same side as the cable exits, in the direction of the width of the black borders, the connection dimension C between the display module 1 and the middle frame 3 in this application is the same. 1 equal Figure 1 The connection dimension C between the display module 1” and the middle frame 3” in the electronic device shown is given, and both schemes assume that the gap between the transparent cover and the frame is the same, and the width of the black border of the display module itself is also the same (A=A'). Specifically, on the side where the cable exits, Figure 1 The black border width of the electronic device shown is A+B+C, while the black border width d1 of the electronic device provided in this embodiment is A'+C. 11 In this embodiment, the U-shaped structure of the flexible circuit board 12 is part of the black border of the display module 1 itself. On the side where the outgoing cable is located, the U-shaped structure of the flexible circuit board 12 is embedded in the first connecting portion 41. That is, in the direction of the width of the black border, the black border of the display module 1 itself overlaps with the first connecting portion 41. Let the dimension of this overlapping area in the direction of the width of the black border be C. 12 Then C 1 =C 11 +C 12 And C 1 =C, therefore, C 11 <C. Furthermore, A' = A, therefore, compared to Figure 1 The electronic device shown in this application embodiment has a smaller black border and a higher screen-to-body ratio. For example, C 11 If the width is less than or equal to 0.4 mm, then the black border width on the side where the cable outlet is located in the electronic device provided in this application embodiment is relatively small. Figure 1The solution shown is more than 0.4 mm smaller.

[0024] Figure 5 for Figure 1 A cross-sectional view of another part of the electronic device shown. (As shown) Figure 5 As shown, the width of the black border of display module 1" itself, excluding the area where the cable ends are located, is A. 0 In the same direction, the clearance between display module 1” and middle frame 3” is B. 0 The dimension of the step surface is C 0 Then the width of the black border of the electronic device is A. 0 +B 0 +C 0 Next, please refer to... Figure 4 In this embodiment of the application, the width of the black border of the display module 1 itself, excluding the area where the cable outlet is located, is A”, and the dimension of the second connecting portion 42 in the same direction is C”. 2 The second connecting part 42 extends beyond the size of the display module by C. 21 The dimension of the overlapping area between the width of the black border of module 1 and the second connecting part 42, displayed in the width direction of the black border, is C. 22 C 2 =C 21 +C 22 The total width d2 of the black border at the edge of the electronic device, excluding the area where the cable ends are located, is A”+C. 21 Similarly, under the same conditions, C 0 =C 2 Therefore, C 21 <C 0 In addition, A 0 =A”, therefore, compared to Figure 1 The electronic device shown in this application embodiment has a smaller black border and a higher screen-to-body ratio.

[0025] Furthermore, the first connecting portion 41 embeds the bent portion of the flexible circuit board 12 within the first connecting portion 41. Therefore, the thickness of the first connecting portion 41 is greater than the thickness of the display unit 11, and the required thickness of the first connecting portion 41 is greater than the required thickness of the second connecting portion 42. In this embodiment, the thickness of the second connecting portion 42 is less than or equal to the thickness of the first connecting portion 41. This increases the screen-to-body ratio of the electronic device while fully utilizing the overall space of the electronic device and minimizing its thickness.

[0026] It is worth noting that the first connecting piece 4 does not extend beyond the edge of the transparent cover plate 2. That is, the edge of the transparent cover plate 2 can extend slightly beyond the first connecting piece 4, and the edge of the transparent cover plate 2 can also be flush with the edge of the first connecting piece 4. In specific implementation, the specific relationship between the edge of the transparent cover plate 2 and the edge of the first connecting piece 4 depends on the manufacturing precision. Therefore, it should be understood that even if the edge of the transparent cover plate 2 extends beyond the first connecting piece 4, the extent of this extension is negligible. Furthermore, the thickness of each component mentioned in this embodiment refers to the dimension of that component in the direction perpendicular to the transparent cover plate 2. In addition, it should be understood that a gap between the edge of the transparent cover plate 2 and the frame 32 is a necessary condition for the transparent cover plate 2 to be installed in the middle frame 3. If the external dimensions of the transparent cover plate 2 are exactly the same as the internal dimensions of the frame 32, then the transparent cover plate 2 cannot be installed in the frame 32. In other words, the gap between the edge of the transparent cover plate 2 and the frame 32 is required for installation and may not be visible to the naked eye. In practice, after the transparent cover plate 2 is installed in place on the middle frame 3, the gap between the edge of the transparent cover plate 2 and the frame 32 can be filled by means of glue injection.

[0027] In specific implementation, the surface of the first connector 4 facing the transparent cover 2 is fixedly connected to the transparent cover 2 to support the transparent cover 2, thereby reducing the possibility of damage to the transparent cover 2 during assembly and in drop scenarios. Furthermore, the first connector 4 and the middle plate 31 can be bonded together. For example, the first connector 4 and the middle plate 31 can be bonded by dispensing adhesive or by using adhesive backing.

[0028] In some embodiments, the transparent cover 2 can be a glass cover (CG). Of course, the transparent cover 2 is not limited to a glass cover, and can also be other covers that meet display requirements and have protective properties. The end of the frame 32 opposite to the transparent cover can be connected to a back cover 6. The back cover 6 and the middle frame 3 together enclose a space for accommodating components such as batteries.

[0029] In one specific embodiment, the first connecting part 41 and the second connecting part 42 are integrally molded plastic components. This reduces the number of steps required to connect the first connecting part 41 and the second connecting part 42, simplifying the assembly process. Furthermore, the circumferential sealing performance of the first connecting part 4 is better guaranteed, which is more beneficial for the waterproofing of electronic devices. Further, the first connecting part 4 can be integrally molded with the transparent cover plate 2 and the display module 1 using a room-temperature injection molding process, thus making the connection and sealing between it and the transparent cover plate 2 and the display module 1 more reliable. Of course, the first connecting part 4 can also be integrally molded with the display module 1 using an injection molding process, allowing the first connecting part 4 to be bonded to the transparent cover plate 2. It should be understood that the connection methods between the first connecting part 4 and the transparent cover plate 2 and the display module 1 are not limited to the above two methods; the above two connection methods are merely examples and not limitations.

[0030] Figure 6 A schematic diagram of the structure of a first connector 4 in an electronic device according to an embodiment of this application is shown. Figure 6 As shown, the second connecting portion 42 includes a first sub-connecting portion 421 and two second sub-connecting portions 422, wherein the first sub-connecting portion 421 is opposite to the first connecting portion 41, and the two second sub-connecting portions 422 are connected between the first sub-connecting portion 421 and the first connecting portion 41. Further, in one specific embodiment, the thickness of the first sub-connecting portion 421 is less than the thickness of the first connecting portion 41. In another specific embodiment, as... Figure 7 As shown, the thickness of the section of the second sub-connector 422 away from the first connector 41 is less than the thickness of the first connector 41. Of course, in some embodiments, the thickness of the first sub-connector 421 can also be less than the thickness of the first connector 41, and the thickness of the section of the second sub-connector 422 away from the first connector 41 can also be less than the thickness of the first connector 41. The end of the electronic device away from the first connector 41 typically needs to stack components such as the motherboard, front-facing camera, and receiver, making space more limited. Making the thickness of the second connector 42 smaller in the corresponding area is beneficial for fully utilizing the overall space and for controlling the overall thickness of the electronic device.

[0031] Please combine Figures 6-8 The second sub-connecting portion 422 includes a first segment 4221 and a second segment 4222 located on the side opposite to the first connecting portion 41. The thickness of the first segment 4221 is greater than the thickness of the second segment 4222. The thickness gradually decreases at the end where the first segment 4221 connects to the second segment 4222. Figure 7 As shown, or, as Figure 8As shown, the connection between the first segment 4221 and the second segment 4222 is stepped. It should be understood that, due to limitations in the manufacturing process, the stepped corners may have rounded corners or other chamfered shapes. Furthermore, it is worth noting that, depending on actual needs, each second sub-connecting portion 422 may include one set of first segments 4221 and second segments 4222, or it may include multiple sets of first segments 4221 and second segments 4222. For example, each second sub-connecting portion 422 may include two or three sets of first segments 4221 and second segments 4222.

[0032] Figure 9 A partial cross-sectional view of another electronic device provided as an embodiment of this application. (See attached image.) Figure 9 As shown, the first connecting part 41 includes a screen connecting part 411 and a mid-frame connecting part 412. The screen connecting part 411 embeds the portion of the flexible circuit board 12 located at the wire outlet end into the screen connecting part 411. The mid-frame connecting part 412 is fixedly connected to the side of the screen connecting part 411 opposite to the transparent cover plate 2. The mid-plate 31 is provided with a first limiting part 311. The mid-frame connecting part 412 is fixedly connected to the first limiting part 311. Thus, through the cooperation of the mid-frame connecting part 412 and the first limiting part 311, the connection between the first connecting part 41 and the mid-plate 31 is strengthened, making the connection between the first connecting part 41 and the mid-plate 31 more reliable. This can further mitigate the impact between the display module 1 and the mid-frame 3 during a drop and better protect the display module 1. Exemplarily, one of the mid-frame connecting part 412 and the first limiting part 311 includes a mounting groove, and the other includes a boss. The boss is inserted into the mounting groove and fixedly connected to the mounting groove. In this design, the relative movement between the first connector 4 and the middle plate 31 in the direction parallel to the middle plate 31 can be further restricted by the cooperation of the mounting groove and the boss.

[0033] In one specific embodiment, the mid-frame connecting portion 412 includes a boss, and the first limiting portion 311 includes a mounting groove. The dimension of the end of the boss near the screen connecting portion 411 is greater than or equal to the dimension of the end of the boss away from the screen connecting portion 411. In another specific embodiment, the mid-frame connecting portion 412 includes a mounting groove, and the first limiting portion 311 includes a boss. The dimension of the end of the boss near the screen connecting portion 411 is less than or equal to the dimension of the end of the boss away from the screen connecting portion 411. In both of the above solutions, when all other connections between the first connector 4 and the mid-frame 3 are released, that is, when the only remaining connection between the first connector 4 and the mid-frame 3 is the connection between the mounting groove and the boss, the first connector 41 can be pulled out from the mid-plate 31 without damaging the first connector 41 and the mid-plate 31, which facilitates the maintenance of electronic devices.

[0034] Please continue to refer to Figure 9In some embodiments, the surface of the mounting groove for connecting with the first connecting portion 41 is provided with an adhesive layer a, and the boss is bonded to the mounting groove through the adhesive layer a. Alternatively, the adhesive layer a can also be provided on the surface of the first connecting portion 41 for connecting with the mounting groove. Exemplarily, the adhesive layer a can be applied to the surface of the corresponding mounting groove or the first connecting portion 41 by dispensing adhesive.

[0035] Please continue to refer to Figure 9 In some embodiments, the middle frame 3 includes a first sidewall for connecting to the first connecting portion 41. The first sidewall has a receiving groove, the opening of which faces the display module 1. The electronic device also includes a limiting member 5. The limiting member 5 is fixed in the receiving groove and abuts against the first connecting portion 41, that is, the limiting member 5 and the first connecting member are interference-fitted to strengthen the connection between the first connecting portion 41 and the frame 32, further mitigating the impact between the display module 1 and the middle frame 3 during a drop. Exemplarily, the limiting member 5 includes a limiting strip made of soft rubber with a Shore hardness of 20~50HA, for example: the Shore hardness of the limiting strip is 20HA, 25HA, 38HA or 50HA, etc. The soft rubber limiting strip can be processed and installed in the receiving groove of the first sidewall, or it can be integrally molded with the frame 32. Of course, the limiting member 5 can also be in other forms, which will not be listed here. Furthermore, in practical implementation, the number of receiving slots on the first sidewall can be set according to actual needs; for example, the number of receiving slots can be one, two, or three. It is easy to understand that each receiving slot is equipped with a limiting element 5.

[0036] Figure 10 This is a structural diagram of another electronic device provided in an embodiment of this application. Figure 11 for Figure 10 The image shows a cross-sectional view of the electronic device. (See image.) Figures 10-11As shown, another electronic device provided in this application embodiment includes a display module 1', a transparent cover plate 2', a middle frame 3', and a second connector 8. Specifically, the transparent cover plate 2' is fixed to the light-emitting surface of the display module 1'. The display module 1' includes a display unit 11' and a flexible circuit board 12'. One end of the display unit 11' is the output terminal, and one end of the flexible circuit board 12' is connected to the output terminal. The other end of the flexible circuit board 12' is located on the side of the display unit 11' opposite to the transparent cover plate 2' and extends in a direction pointing towards the center of the display unit 11'. The second connector 8 is located on the side of the transparent cover plate 2' facing the display module 1'. The second connector 8 includes a third connecting part 81 and a fourth connecting part 82. The third connecting part 81 embeds the portion of the flexible circuit board 12' located at the output terminal into the third connecting part 81. The fourth connecting part 82 is fixedly connected to the side of the third connecting part 81 opposite to the transparent cover plate 2'. The orthographic projections of the display module 1' and the second connector 8 on the plane where the transparent cover plate 2' is located are both on the transparent cover plate 2'. The middle frame 3' includes a middle plate 31' and a side frame 32'. The middle plate 31' is located within the area enclosed by the side frame 32', and the middle plate 31' is fixedly connected to the side frame 32'. The middle plate 31' is provided with a second limiting part 311' corresponding to the fourth connecting part 82. The fourth connecting part 82 is fixedly connected to the second limiting part 311', and there is a gap between the edge of the transparent cover plate 2' and the side frame 32'.

[0037] In this design, the third connecting part 81 embeds the portion of the flexible circuit board 12' located at the outgoing end. The third connecting part 81 can protect the portion of the display module 1' located at the outgoing end during the assembly of the electronic device and in scenarios such as drops, preventing it from colliding with the middle frame 3'. Therefore, there is no need to provide a clearance gap between the portion of the display module 1' located at the outgoing end and the middle frame 3'. Simultaneously, it is fixedly connected to the second limiting part 311' on the middle plate 31' via the fourth connecting part 82. Compared to... Figure 1 The electronic device shown eliminates the clearance between the display module 1' and the bezel 32', therefore, under the same conditions, compared to Figure 1 The electronic device shown in this embodiment allows for a larger display area for the display unit 11' and a smaller black border ratio for the display module 1', resulting in a larger screen-to-body ratio. Specifically, let A be the width of the black border of the display module 1' on the side where the output cable is located. 1 Let the dimension of the third connecting part 81 in the same direction be C. 3 The third connection part 81 extends beyond the size of the flexible circuit board by C. 31 Under the same conditions, that is, when the shape and area of ​​the display modules are the same, and the width of the black border at all ends of the display module except for the end where the cable exits is located is the same, and also on the side where the cable exits is located, in the direction of the width of the black border: the connection dimension C between the display module 1' and the middle frame 3' in this application is... 3equal Figure 1 The connection dimension C between the display module 1' and the middle frame 3' in the electronic device shown is given. In both schemes, the gap between the transparent cover and the frame is the same, and the width of the black border of the display module 1' itself is the same (A=A). 1 Under the same condition, the width of the black border on other parts of the display module 1' is also the same. Specifically, on the side where the cable outlet is located: Figure 1 The black border width of the electronic device shown is A+B+C, and the black border width d1' of the electronic device provided in this embodiment is A. 1 +C 31 In this embodiment, on the side where the output terminal is located, the U-shaped structure of the flexible circuit board 12' is part of the black border of the display module 1' itself. The U-shaped structure of the flexible circuit board 12' is embedded in the third connecting part, that is, the black border of the display module 1' itself overlaps with the third connecting part 81. Let C be the dimension of this overlapping area in the width direction of the corresponding black border. 32 Then C 3 =C 31 +C 32 And C 3 =C, therefore, C 31 <C. In addition, A 1 =A, therefore, compared to Figure 1 The electronic device shown in this application embodiment has a smaller black border and a higher screen-to-body ratio. Furthermore, the display module 1' is fixedly connected to the second limiting part 311' on the middle plate 31' via the fourth connecting part 82, which can further mitigate the impact between the display module 1' and the middle frame 3' during a drop, and better protect the display module 1'.

[0038] Similarly, it should be understood that even if the edge of the transparent cover plate 2' extends beyond the third connecting portion 81, the extent of this extension is negligible. The gap between the edge of the transparent cover plate 2' and the frame 32' is necessary for installation and may not be visible to the naked eye. In practice, after the transparent cover plate 2' is installed in place on the middle frame 3', the gap between the edge of the transparent cover plate 2' and the frame 32' can be filled by methods such as glue injection.

[0039] In one specific embodiment, the fourth connecting portion 82 includes a boss, and the second limiting portion 311' includes a mounting groove. The dimension of the boss near the third connecting portion 81 is greater than or equal to the dimension of the boss away from the third connecting portion 81. In another specific embodiment, the fourth connecting portion 82 includes a mounting groove, and the second limiting portion 311' includes a boss. The dimension of the boss near the third connecting portion 81 is less than or equal to the dimension of the boss away from the third connecting portion 81. In both of these embodiments, when all other connections between the fourth connecting portion 82 and the middle frame 3' are released—that is, when the only remaining connection between the fourth connecting portion 82 and the middle frame 3' is the connection between the mounting groove and the boss—the boss can be pulled out of the mounting groove without damaging the fourth connecting portion 82 and the middle frame 31', making it easier to maintain the electronic device.

[0040] In some embodiments, a back cover 6' may be connected to the end of the frame 32' opposite to the transparent cover plate, and the back cover 6' and the middle frame 3' together enclose a space for accommodating components such as batteries.

[0041] Please continue to refer to Figure 11 In some embodiments, the surface of the mounting groove for connecting with the fourth connecting portion 82 is provided with an adhesive layer b, and the boss is bonded to the mounting groove through the adhesive layer b. Alternatively, the adhesive layer b can also be provided on the surface of the fourth connecting portion 82 for connecting with the mounting groove. Exemplarily, the adhesive layer b can be applied to the surface of the corresponding mounting groove or the fourth connecting portion 82 by dispensing adhesive.

[0042] Please continue to refer to Figure 11 In some embodiments, the middle frame 3' includes a second sidewall for connecting with the third connecting portion 81. The second sidewall has a receiving groove, the opening of which faces the display module 1'. The electronic device also includes a limiting member 5'. The limiting member 5' is fixed in the receiving groove and abuts against the third connecting portion 81 to strengthen the connection between the third connecting portion 81 and the frame 32', further mitigating the impact between the display module 1' and the middle frame 3' during a drop, and preventing the screen from failing due to impact. Exemplarily, the limiting member 5' includes a limiting strip made of soft rubber with a Shore hardness of 20~50HA, for example, a Shore hardness of 20HA, 25HA, 38HA, or 50HA. The soft rubber limiting strip can be processed and installed in the receiving groove of the second sidewall, or it can be injection molded integrally with the frame 32'. Of course, the limiting member 5' can also be in other forms, which will not be listed here. Furthermore, in practical implementation, the number of receiving slots on the second sidewall can be set according to actual needs; for example, the number of receiving slots can be one, two, or three. It is easy to understand that each receiving slot is equipped with a limiting element 5'.

[0043] With the side where the display module 1' connects to the third connecting part 81 as the first side, in some embodiments, the display module 1' further includes a second side, a third side, and a fourth side, with the first side opposite to the second side and the third side opposite to the fourth side; the middle plate 31' satisfies at least one of the following conditions: The middle plate 31' is provided with a first adhesive layer 91, and the first adhesive layer 91 is bonded to a portion of the display module 1' adjacent to the second side. The middle plate 31' is provided with a second adhesive layer 92, and the second adhesive layer 92 is bonded to the portion of the display module 1' adjacent to the third side. The middle plate 31' is provided with a third adhesive layer 93, which is bonded to the portion of the display module 1' adjacent to the fourth side.

[0044] Figure 12 for Figure 10 The electronic device shown is a cross-sectional view (FF) of the device. Figure 12 As shown, in one specific embodiment, the middle plate 31' is provided with the aforementioned first adhesive layer 91, second adhesive layer 92, and third adhesive layer 93. The first adhesive layer 91, second adhesive layer 92, third adhesive layer 93, and third connecting portion 81 are connected end-to-end, forming a closed-loop structure covering the entire circumference of the display module 1', thereby fixing the transparent cover plate 2' and the display module 1' to the middle frame 3' and achieving a sealed and waterproof connection between the display module 1' and the middle frame 3'. In this solution, compared to the portion of the display module 1' other than the cable outlet, the... Figure 1 The proposed solution eliminates the stepped surface of the middle frame 3', and the display module and middle frame are now connected by the side of the display module opposite to the light-emitting surface, thereby reducing the size of the black border of the display module 1'. In this solution, the black border width d2' of the electronic device, excluding the cable outlet, is A1+B1, where A1 is the width of the black border of the display module 1' itself, and B1 is the clearance between the display module 1' and the frame 32'. B1 is generally greater than or equal to 0.3, so the black border width d2' of the electronic device is A+0.3 mm, which is larger than... Figure 1 The black border size of the scheme shown is more than 0.5 mm smaller.

[0045] For example, the first adhesive layer 91, the second adhesive layer 92, and the third adhesive layer 93 can all be solid adhesives such as backing adhesive (e.g., die-cut backing adhesive), or they can all be adhesives that are applied to the middle plate 31' by dispensing and cured after standing. The specific bonding positions of the first adhesive layer 91, the second adhesive layer 92, and the third adhesive layer 93 on the display unit 11' are set according to actual needs. For example, all three can be bonded to the copper foil on the side of the display unit 11' opposite to the light-emitting side, or to the back plate of the display module 1', etc.

[0046] Figure 13 for Figure 10A schematic diagram of a partial structure of the electronic device shown. Figure 13 As shown, in some embodiments, a potting molded part 94 may be provided at the junction of the second adhesive layer 92 and the third adhesive layer 93 and the second connector 8. Specifically, the glue may be potted from the side of the middle frame 3' away from the display module 1'. After the glue is cured, it becomes the potting molded part 94. The potting molded part 94 is seamlessly connected to the second adhesive layer 92 and the third adhesive layer 93, thereby achieving a seal at the junction of the second adhesive layer 92 and the third adhesive layer 93 and the second connector 8.

[0047] Figure 14 This is a schematic diagram of a partial structure of another electronic device. (Example) Figure 14 As shown, in some embodiments, the electronic device includes a display module 1. 0 2 transparent covers 0 and middle frame 3 0 Specifically, the middle frame includes the middle plate 31 0 and border 32 0 , medium plate 31 0 Located on the border 32 0 Within the enclosed area, and the middle plate 31 0 With border 32 0 Fixed connection. Display module 1 0 Set on the middle plate 31 0 2 transparent covers 0 Fixed to display module 1 0 The light-emitting surface, and the transparent cover plate 2 0 The edge extends beyond the display module 1 0 The edge. Furthermore, transparent cover 2 0 Orientation of display module 1 0 The surface is provided with a support part 21 0 Display Module 1 0 Includes display unit 11 0 And flexible circuit board, display unit 11 0 One end is the output end, and the flexible circuit board includes a first end, a second end, and a connecting section 121. 0 The first end is connected to the output end, and the second end is located in the display unit 11. 0 With transparent cover 2 0 The opposite side, and pointing towards the display unit 11 0 Extending in the direction of the center, connecting segment 121 0 Located in display unit 11 0 With border 32 0 Between, and connecting segment 121 0 Connect the first end and the second end. Support part 21 0 Connecting segment 121 0 It abuts and points towards the frame 32 along the outgoing end. 0The direction of the part adjacent to the outgoing end (that is, the W direction in the figure), connecting segment 121 0 With transparent cover 2 0 The distance between them gradually increases. That is to say, in the support part 21 0 Under the influence of the W direction, connecting segment 121 0 Towards the middle plate 31 0 The location is tilted. Additionally, support section 21... 0 In the middle plate 31 0 The orthographic projection on is located at the connecting segment 121 0 In the middle plate 31 0 Within the range of the orthographic projection on the surface. That is to say, support part 21 0 In the middle plate 31 0 The range of the orthographic projection on the surface can be smaller than that of the connecting segment 121. 0 In the middle plate 31 0 The range of the orthographic projection on the surface, and the support portion 21 0 In the middle plate 31 0 The orthographic projection of the top falls into the connecting segment 121 0 In the middle plate 31 0 Within the range of the orthographic projection on the surface; support 21 0 In the middle plate 31 0 The range of the orthographic projection on can also be connected to segment 121. 0 In the middle plate 31 0 The areas of the orthographic projections on the surface overlap. In this scheme, the connection segment 121 of the flexible circuit board... 0 In support section 21 0 Under the action of the middle plate 31 0 The orientation is tilted, compared to the setting in the direction of the tilt. Figure 1 In the case where the connecting segment is set horizontally, connecting segment 121 0 The dimensions in the width direction of the black border are smaller, thus enabling the electronic device provided by this solution to be more efficient than those under the same conditions. Figure 1 The electronic device shown has a smaller black border on its display module. In other words, under the same conditions, compared to... Figure 1 The electronic device shown in this application embodiment enables a larger display area for the display module, display module 1. 0 The black border is smaller, which means the screen ratio of electronic devices is larger.

[0048] It is worth noting that in some embodiments, the middle plate 31 is configured according to actual needs. 0 Orientation of display module 1 0 One side may be provided with a way to avoid the connecting section 121 0 The groove. Of course, in some other embodiments, the connecting segment 121 may also be used. 0 with mid plate 31 0There is a gap between them, without the need for the middle plate 31 0 The upper part is set to avoid the connecting section 121 0 The groove.
