[0001] This application claims priority to Chinese Patent Application No. 202411862292.X, filed on December 16, 2024, entitled “Electronic Device”, the entire contents of which are incorporated herein by reference. Technical Field
[0002] This application relates to the field of electronic equipment technology, and more particularly to an electronic device. Background Technology
[0003] With the continuous development of science and technology, mobile phones and other electronic devices are widely used in people's daily lives and work, becoming indispensable everyday items. Currently, electronic devices often use circuit boards to realize signal transmission between various electronic components. However, because the structure of the circuit board needs to be adapted to structural components such as the frame, the narrow strips of the circuit board are not strong enough and are prone to breakage, reducing the reliability of electronic devices. Summary of the Invention
[0004] This application provides an electronic device for improving the strength of narrow strip locations on a circuit board, thereby enhancing the reliability of the electronic device.
[0005] The electronic device described in this application includes a circuit board, a mid-frame, and a reinforcing member. The circuit board has a first clearance hole that penetrates the circuit board along its thickness direction. The circuit board includes a narrow strip located on one side of the first clearance hole.
[0006] The middle frame is provided with a protrusion, which is located on the bottom surface of the middle frame and protrudes from the bottom surface of the middle frame to the top surface, and passes through the first clearance hole.
[0007] The reinforcing member includes a cover portion and a first reinforcing portion. The cover portion covers the protrusion and passes through the first clearance hole. The first reinforcing portion is fixedly connected to the peripheral side of the cover portion and is located between the middle frame and the narrow strip portion, and is installed on the narrow strip portion to reinforce the narrow strip portion.
[0008] In the electronic device described in this application, the reinforcing member is a non-planar structure, and the cover portion has 3D structural features such as bending. The reinforcing member has a large horizontal area and three-dimensional strength, which can further enhance the stress in weak areas such as the narrow strip portion, effectively reinforce the circuit board, prevent the narrow strip portion from breaking, improve the strength of the narrow strip portion, and improve the reliability of the electronic device.
[0009] In one embodiment, the middle frame includes a middle plate and a side frame. The middle plate is provided with the protrusion, and the side frame is located outside the middle plate and fixedly connected to the middle plate. The side frame includes a first radiator, which is located on one side of the first clearance hole.
[0010] The circuit board further includes a first part and a second part. The first part and the first radiator are located on the same side of the first clearance hole, and the second part is located on the side of the first clearance hole away from the first part. The narrow strip is fixedly connected between the first part and the second part.
[0011] The circuit board is provided with an antenna mount and a first antenna feed line. The antenna mount is located on the bottom surface of the first part, and the first antenna feed line is located on the bottom surface of the first part, the bottom surface of the narrow strip part, and the bottom surface of the second part, and is electrically connected between the antenna mount and the first radiator.
[0012] Both the antenna mount and the first antenna feed line are located on the side of the circuit board away from the mid-frame, which reduces the impedance impact of the mid-frame on the antenna mount and the first antenna feed line, reduces antenna insertion loss, ensures the communication stability of the electronic device, and improves the reliability of the electronic device. Furthermore, since the reinforcing member strengthens the narrow strip, the narrow strip will not break, ensuring that the first antenna feed line can stably supply power to the first radiator from the antenna mount along the narrow strip, thus ensuring the communication stability of the electronic device and improving its reliability.
[0013] In one embodiment, the reinforcing member further includes a second reinforcing part, which is fixedly connected to the peripheral side of the cover part and located between the middle frame and the first part, and is installed on the first part to reinforce the first part.
[0014] In one embodiment, the reinforcing member further includes a third reinforcing part, which is fixedly connected to the peripheral side of the cover part and located between the middle frame and the second part, and is installed on the second part to reinforce the second part.
[0015] In one embodiment, the circuit board further includes a connecting portion located on the side of the first clearance hole away from the narrow strip portion, and fixedly connected between the first portion and the second portion, and forming the first clearance hole together with the first portion, the second portion and the narrow strip portion.
[0016] The reinforcing member further includes a fourth reinforcing part, which is fixedly connected to the peripheral side of the cover part and located between the middle frame and the connecting part, and is installed on the connecting part to reinforce the connecting part.
[0017] In one embodiment, the middle frame is further provided with a second clearance hole and a clearance groove. The second clearance hole penetrates the middle frame along the thickness direction of the middle frame. The opening of the clearance groove is located on the top surface of the middle frame. The clearance groove is recessed from the top surface of the middle frame in the direction of the protrusion and communicates with the second clearance hole.
[0018] The electronic device further includes a display panel, a connecting circuit board, and a display device. The display panel is mounted on the top surface of the middle frame. The connecting circuit board is disposed between the display panel and the middle frame and is electrically connected to the display panel. The display device is mounted on the side of the connecting circuit board away from the display panel and passes through the third clearance hole and the clearance groove.
[0019] In the electronic device described in this application, the middle frame is provided with a second clearance hole and a clearance groove to avoid the display device. The display device can reuse the thickness space of the middle frame, which can reduce the thickness of the electronic device and help to achieve a thinner and lighter design. Moreover, the design of the clearance groove can reduce the area of holes on the middle frame, ensure the overall strength of the middle frame, and help improve the reliability of the electronic device.
[0020] In one embodiment, the display device is spaced apart from the bottom wall of the clearance groove to avoid interference between the display device and the middle frame.
[0021] In one embodiment, the circuit board further includes a third clearance hole, which penetrates the circuit board along its thickness direction and is located on the side of the narrow strip portion opposite to the first clearance hole. The narrow strip portion is situated between the first clearance hole and the third clearance hole.
[0022] The middle frame is also provided with mounting holes. The opening of the mounting holes is located on the peripheral side of the middle frame. The mounting holes are recessed from the peripheral side of the middle frame toward the protrusion and penetrate through the bottom surface of the middle frame, and communicate with the third clearance hole.
[0023] The electronic device further includes a functional module, which is installed in the mounting hole and is disposed opposite to the third clearance hole.
[0024] In one embodiment, the cover portion includes a cover plate portion and a side plate portion. The cover plate portion is located on the side of the bottom surface of the protrusion away from the middle frame and covers the bottom surface of the protrusion. The side plate portion is fixedly connected to the peripheral side surface of the cover plate portion and is disposed around the cover plate portion, and is located between the peripheral side surface of the protrusion and the hole wall surface of the first clearance hole. The first reinforcing portion is fixedly connected to the end of the side plate portion away from the cover plate portion.
[0025] In the electronic device described in this application, the reinforcing member is a non-planar structure, and the cover portion has 3D structural features such as bending. The reinforcing member has a large horizontal area and three-dimensional strength, which can further enhance the stress in weak areas such as the narrow strip portion, effectively reinforce the circuit board, prevent the narrow strip portion from breaking, improve the strength of the narrow strip portion, and improve the reliability of the electronic device.
[0026] In one embodiment, the electronic device includes a first body, a second body, and a hinge mechanism. The first body includes the circuit board, the mid-frame, and the reinforcing member. The hinge mechanism is connected between the first body and the second body. Attached Figure Description

[0037] The technical solutions in this application will now be clearly and completely described with reference to the accompanying drawings.
[0038] Please refer to Figures 1 and 2. Figure 1 is a structural schematic diagram of the electronic device 1000 provided in this application in a folded state, and Figure 2 is a structural schematic diagram of the electronic device 1000 shown in Figure 1 in a flattened state.
[0039] The electronic device 1000 can be an electronic product such as a mobile phone, tablet computer, personal computer, multimedia player, e-book reader, laptop computer, in-vehicle equipment, or wearable device. In this embodiment, the electronic device 1000 is a foldable mobile phone. That is, the electronic device 1000 is a mobile phone that can switch between a folded state and a flattened state.
[0040] Next, for ease of description, we define the width direction of the electronic device 1000 shown in Figure 2 as the X-axis direction, the length direction as the Y-axis direction, and the thickness direction as the Z-axis direction. The X-axis, Y-axis, and Z-axis directions are mutually perpendicular. For example, the extension direction of the rotation axis of the electronic device 1000 is parallel to the Y-axis direction. That is, the electronic device 1000 can be relatively unfolded or folded around the Y-axis direction.
[0041] It should be noted that the terms "parallel" and "perpendicular" used in this application to describe relative positional relationships are relative to the current technological level, and not absolute or strict mathematical definitions. Slight deviations are permissible; approximations of parallelism and perpendicularity are acceptable. For example, "A and B are parallel" means that A and B are parallel or approximately parallel, and the angle between A and B can be between 0 and 10 degrees. Similarly, "A and B are perpendicular" means that A and B are perpendicular or approximately perpendicular, and the angle between A and B can be between 80 and 100 degrees.
[0042] In Figure 1, the electronic device 1000 is in a folded state. In this state, the electronic device 1000 has a smaller dimension along the X-axis, making it easy to carry. In Figure 2, the electronic device 1000 is in a flattened state. For example, the unfolded angle of the electronic device 1000 in Figure 2 can be 180 degrees. In this state, the electronic device 1000 has a larger dimension along the X-axis, providing a larger display area.
[0043] It should be noted that slight deviations are allowed in the angles illustrated in this application. For example, the unfolding angle of the electronic device 1000 shown in Figure 2 as 180 degrees means that the unfolding angle of the electronic device 1000 can be 180 degrees, or approximately 180 degrees, such as 170 degrees, 175 degrees, 185 degrees, and 190 degrees. The angles illustrated in the following text can be understood in the same way. It should be understood that the electronic device 1000 shown in this application is a terminal capable of folding twice. In some other embodiments, the electronic device 1000 may also be a terminal capable of folding three or more times.
[0044] Electronic device 1000 includes an electronic device 100 and a display module 200, with the display module 200 mounted on the electronic device 100. The electronic device 100 includes a first body 110, a second body 120, and a pivot mechanism 130. The pivot mechanism 130 connects the first body 110 and the second body 120 to achieve a rotatable connection between them. The first body 110 and the second body 120 can rotate relative to each other via the pivot mechanism 130. The pivot mechanism 130 allows the electronic device 100 to switch between a folded state and a flattened state.
[0045] As shown in Figure 1, when the electronic device 100 is in the folded state, the first main body 110 and the second main body 120 are folded relative to each other, and the rotating mechanism 130 is in the folded state. When the electronic device 100 is in the flattened state, as shown in Figure 2, the first main body 110 and the second main body 120 are flattened relative to each other, and the included angle between the first main body 110 and the second main body 120 can be 180 degrees, and the rotating mechanism 130 is in the flattened state.
[0046] Please refer to Figures 3 to 5 together. Figure 3 is a partial structural schematic diagram of the first main body 110 of the electronic device 100 in the electronic device 1000 shown in Figure 2. Figure 4 is a structural schematic diagram of the first main body 110 shown in Figure 3 from another angle. Figure 5 is an exploded structural schematic diagram of the first main body 110 shown in Figure 4.
[0047] The first main body 110 includes a housing 10, a functional module (not shown), a circuit board 20, and a reinforcing member 30. The functional module, circuit board 20, and reinforcing member 30 are all mounted on the housing 10. The housing 10 includes a middle frame 11 and a rear cover 12, with the rear cover 12 disposed on the middle frame 11. The middle frame 11 has a protrusion 11a. The protrusion 11a is located on the bottom surface 111 of the middle frame 11 and protrudes from the bottom surface 111 of the middle frame 11 in a direction away from the top surface 112 (the negative Z-axis direction in the figure), and is spaced apart from the peripheral side surface 113 of the middle frame 11. For example, the thickness of the middle frame 11 is less than or equal to 0.3 mm.
[0048] It should be noted that the directional terms such as "top," "bottom," "left," and "right" used in the description of the electronic device 1000 in this application embodiment are mainly based on the orientation of the electronic device 1000 shown in the accompanying drawings. "Top" refers to the positive Z-axis direction, "bottom" refers to the negative Z-axis direction, "right" refers to the positive X-axis direction, and "left" refers to the negative X-axis direction. These terms do not constitute a limitation on the orientation of the electronic device 1000 in actual application scenarios.
[0049] The middle frame 11 is also provided with a second clearance hole 11b, a clearance groove 11c, and a mounting hole 11d. The second clearance hole 11b is located on one side of the protrusion 11a. The opening of the second clearance hole 11b is located on the top surface 112 of the middle frame 11. The second clearance hole 11b is recessed from the top surface 112 of the middle frame 11 towards the bottom surface 111 (in the negative Z-axis direction shown in the figure) and penetrates through the bottom surface 111 of the middle frame 11. That is, the second clearance hole 11b penetrates the middle frame 11 along the thickness direction (in the Z-axis direction shown in the figure) of the middle frame 11.
[0050] The clearance groove 11c is correspondingly disposed to the protrusion 11a and is located on one side of the second clearance hole 11b, and communicates with the second clearance hole 11b. The opening of the clearance groove 11c is located on the top surface 112 of the middle frame 11. The clearance groove 11c is recessed from the top surface 112 of the middle frame 11 towards the protrusion 11a. It should be noted that the corresponding disposal of the clearance groove 11c to the protrusion 11a means that the projection of the clearance groove 11c on the bottom surface 111 of the middle frame 11 is located within the protrusion 11a.
[0051] The mounting hole 11d is located on the side of the protrusion 11a and the clearance groove 11c near the peripheral side surface 113 of the middle frame 11, and is spaced apart from both the protrusion 11a and the clearance groove 11c. The opening of the mounting hole 11d is located on the peripheral side surface 113 of the middle frame 11. The mounting hole 11d is recessed from the peripheral side surface 113 of the middle frame 11 towards the protrusion 11a and the clearance groove 11c (positive Y-axis direction in the figure), and penetrates the bottom surface 111 of the middle frame 11. In some other embodiments, the mounting hole 11d may not penetrate the bottom surface 111 of the middle frame 11, and this application does not impose specific limitations on this.
[0052] In this embodiment, the middle frame 11 includes a middle plate 114 and a side frame 115. The middle plate 114 has a protrusion 11a, a second clearance hole 11b, a clearance groove 11c, and a partial mounting hole 11d. The side frame 115 is located outside the middle plate 114 and is fixedly connected to the middle plate 114, and can be arranged around the middle plate 114. The side frame 115 has a partial mounting hole 11d. The side frame 115 includes a first radiator 116 and a second radiator 117. The first radiator 116 and the second radiator 117 are respectively located on opposite sides of the mounting hole 11d. Specifically, the first radiator 116 is located on the left side of the mounting hole 11d, and the second radiator 117 is located on the right side of the mounting hole 11d. It should be understood that the first radiator 116 and the second radiator 117 can be radiators of the same antenna or radiators of different antennas, and this application does not impose specific limitations on this. For example, the antenna can be a low-frequency antenna or a mid-to-high-frequency antenna.
[0053] The functional module is mounted in the mounting hole 11d. For example, the functional module may be a USB (Universal Serial Bus) interface module. The circuit board 20 is mounted on the bottom surface 111 of the middle frame 11, fitted onto the protrusion 11a, and covers the second clearance hole 11b, while also exposing the functional module. The top surface 201 of the circuit board 20 is spaced apart from the bottom surface 111 of the middle frame 11.
[0054] The circuit board 20 is provided with a first clearance hole 20a and a third clearance hole 20b. The openings of the first clearance hole 20a and the third clearance hole 20b are both located on the top surface 201 of the circuit board 20. Both the first clearance hole 20a and the third clearance hole 20b are recessed from the top surface 201 of the circuit board 20 towards the bottom surface 202 (in the negative Z-axis direction shown in the figure), and penetrate through the bottom surface 202 of the circuit board 20. That is, both the first clearance hole 20a and the third clearance hole 20b penetrate the circuit board 20 along the thickness direction (in the Z-axis direction shown in the figure). The third clearance hole 20b communicates with the mounting hole 11d, penetrates the peripheral side surface of the circuit board 20, and is positioned opposite to the functional module to expose the functional module. Along the Y-axis direction, the first clearance hole 20a is located on one side of the third clearance hole 20b, and is spaced apart from the third clearance hole 20b, avoiding the protrusion 11a. That is, the protrusion 11a passes through the first clearance hole 20a. The hole wall of the first clearance hole 20a surrounds the protrusion 11a and is spaced apart from the peripheral side surface 111a of the protrusion 11a.
[0055] In this embodiment, the circuit board 20 includes a first portion 21, a second portion 22, a narrow strip portion 23, and a connecting portion 24. Along the X-axis, the first portion 21 and the second portion 22 are located on opposite sides of the first clearance hole 20a and the third clearance hole 20b, respectively. Specifically, the first portion 21 and the first radiator 116 are located on the same side of the first clearance hole 20a and the third clearance hole 20b. The second portion 22 and the second radiator 117 are located on the same side of the first clearance hole 20a and the third clearance hole 20b. That is, the second portion 22 and the second radiator 117 are located on the side of the first clearance hole 20a and the third clearance hole 20b away from the first portion 21 and the first radiator 116. Specifically, the first portion 21 and the first radiator 116 are located to the left of the first clearance hole 20a and the third clearance hole 20b, and the second portion 22 and the second radiator 117 are located to the right of the first clearance hole 20a and the third clearance hole 20b.
[0056] Along the Y-axis, the narrow strip 23 is located between the first clearance hole 20a and the third clearance hole 20b, and is fixedly connected between the first part 21 and the second part 22, forming the third clearance hole 20b together with the first part 21 and the second part 22. The connecting part 24 is located on the side of the first clearance hole 20a away from the narrow strip 23, and is fixedly connected between the first part 21 and the second part 22, forming the first clearance hole 20a together with the first part 21, the second part 22 and the narrow strip 23.
[0057] In addition, the circuit board 20 is provided with an antenna mount 40, a first antenna feed line 50, and a second antenna feed line 60. The antenna mount 40, the first antenna feed line 50, and the second antenna feed line 60 are all located on the bottom surface 202 of the circuit board 20. Since the antenna mount 40, the first antenna feed line 50, and the second antenna feed line 60 are all located on the side of the circuit board 20 opposite to the middle frame 11, this reduces the impedance influence of the middle frame 11 on the antenna mount 40, the first antenna feed line 50, and the second antenna feed line 60, which helps to reduce antenna insertion loss, ensure the communication stability of the electronic device 1000, and improve the reliability of the electronic device 1000.
[0058] Specifically, the antenna mount 40 is located on the bottom surface of the second part 22. The first antenna feed line 50 is located on the bottom surface of the second part 22, the bottom surface of the narrow strip 23, and the bottom surface of the first part 21, and is electrically connected between the antenna mount 40 and the first radiator 116. The first antenna feed line 50 can feed the first radiator 116 from the antenna mount 40 along the second part 22, the narrow strip 23, and the first part 21, respectively. The second antenna feed line 60 is located on the bottom surface of the second part 22 and is electrically connected between the antenna mount 40 and the second radiator 117. The second antenna feed line 60 can feed the second radiator 117 from the antenna mount 40 along the second part 22. It should be noted that the antenna mount 40 can serve as the radio frequency terminal of the antenna, and both the first antenna feed line 50 and the second antenna feed line 60 can be metal traces embedded in the circuit board 20; this application does not impose specific limitations on this.
[0059] Please also refer to Figure 6, which is a schematic diagram of the structure of the first main body 110 shown in Figure 4 after being cut along point II. Here, cutting along point II means cutting along the plane containing line II.
[0060] The reinforcing member 30 is installed between the middle frame 11 and the circuit board 20, covering the protrusion 11a and passing through the first clearance hole 20a of the circuit board 20. The reinforcing member 30 includes a cover portion 31, a first reinforcing portion 32, a second reinforcing portion 33, a third reinforcing portion 34, and a fourth reinforcing portion 35. The first reinforcing portion 32, the second reinforcing portion 33, the third reinforcing portion 34, and the fourth reinforcing portion 35 are all located outside the cover portion 31, fixedly connected to the peripheral side of the cover portion 31, and arranged around the cover portion 31. The cover portion 31, the first reinforcing portion 32, the second reinforcing portion 33, the third reinforcing portion 34, and the fourth reinforcing portion 35 can be integrally formed to ensure the overall strength of the reinforcing member 30. For example, the thickness of the reinforcing member 30 can be 0.1 mm.
[0061] The cover portion 31 covers the protrusion 11a and passes through the first clearance hole 20a. The cover portion 31 includes a cover plate portion 311 and a side plate portion 312. The cover plate portion 311 is located on the side of the protrusion 11a opposite to the bottom surface 111 of the middle frame 11 and covers the protrusion 11a. The side plate portion 312 is fixedly connected to the peripheral side surface of the cover plate portion 311, surrounds the cover plate portion 311, and is located between the peripheral side surface 111a of the protrusion 11a and the wall surface of the first clearance hole 20a.
[0062] The first reinforcing part 32, the second reinforcing part 33, the third reinforcing part 34, and the fourth reinforcing part 35 are all fixedly connected to one end of the side plate portion 312 away from the cover plate portion 311, and are all located between the middle frame 11 and the circuit board 20, surrounding the first clearance hole 20a of the circuit board 20, and are also installed on the circuit board 20 to reinforce the circuit board 20. Specifically, the first reinforcing part 32 is located between the middle frame 11 and the narrow strip portion 23, and is installed on the narrow strip portion 23 to reinforce the narrow strip portion 23. For example, the first reinforcing part 32 is installed on the narrow strip portion 23 by welding. The second reinforcing part 33 is located between the middle frame 11 and the first part 21, and is fixedly connected to the first reinforcing part 32, and is installed on the first part 21 to reinforce the first part 21. For example, the second reinforcing part 33 is installed on the first part 21 by welding. The third reinforcing part 34 is located between the middle frame 11 and the second part 22, and is fixedly connected to the first reinforcing part 32. It is also positioned opposite to the second reinforcing part 33 and installed on the second part 22 to reinforce it. Exemplarily, the third reinforcing part 34 is installed on the second part 22 by welding. The fourth reinforcing part 35 is located between the middle frame 11 and the connecting part 24, and is positioned opposite to the first reinforcing part 32. It is connected between the second reinforcing part 33 and the third reinforcing part 34 and is also installed on the connecting part 24. Exemplarily, the fourth reinforcing part 35 is installed on the connecting part 24 by welding. In some other embodiments, the reinforcing part 32 may not include at least one of the second reinforcing part 33, the third reinforcing part 34, and the fourth reinforcing part 35; this application does not impose specific limitations in this regard.
[0063] In this embodiment, the cover portion 31 protrudes relative to the first reinforcing portion 32, the second reinforcing portion 33, the third reinforcing portion 34, and the fourth reinforcing portion 35. That is, the cover portion 31 has 3D structural features such as bending, and the reinforcing member 30 is a non-planar structure. The reinforcing member 30 has a large horizontal area and three-dimensional strength, which can further enhance the stress in weak points such as the narrow strip portion 23 in the circuit board 20, effectively reinforcing the circuit board 20, preventing the narrow strip portion 23 from breaking, ensuring that the first antenna feed line 50 stably feeds the first radiator 116 from the antenna base 40 along the narrow strip portion 23, ensuring the communication stability of the electronic device 1000, and improving the reliability of the electronic device 1000.
[0064] Please refer to Figures 7 through 9. Figure 7 is a structural schematic diagram of the display module 200 in the electronic device 1000 shown in Figure 2 from another angle. Figure 8 is a partial structural schematic diagram of the electronic device 1000 shown in Figure 2. Figure 9 is a structural schematic diagram of the electronic device 1000 shown in Figure 8 after being cut along line II-II. In Figures 8 and 9, only the middle frame 11, circuit board 20, reinforcing member 30, and display device 230 are shown.
[0065] The display module 200 includes a display panel 210, a connecting circuit board 220, and a display device 230. The display panel 210 is mounted on the electronic device 100. The display panel 210 includes a display section 211 and a folding section 212. The display section 211 is mounted on the electronic device 100. The display section 211 has a display surface 2111 and a non-display surface 2112. The display surface 2111 is the surface of the display panel 210 that faces away from the electronic device 100, and the display surface 2111 is used to display information such as text, images, or video. Along the thickness direction of the display section 211, the display surface 2111 and the non-display surface 2112 are arranged opposite to each other.
[0066] In this embodiment, the display unit 211 includes a first display portion 213, a second display portion 214, and a foldable portion 215. The first display portion 213 is mounted on the first main body 110. The first display portion 214 is mounted on the top surface 112 of the middle frame 11. The second display portion 214 is mounted on the second main body 120. The foldable portion 215 connects the first display portion 213 and the second display portion 214 and is disposed opposite to the pivot mechanism 130. The foldable portion 215 can be bent around the Y-axis. It should be understood that Figures 2 and 7 exemplarily show the dividing lines of the first display portion 213, the second display portion 214, and the foldable portion 215, as shown by the dashed lines in the figures, which do not constitute a limitation on the display module 200 in actual application scenarios.
[0067] As shown in Figure 1, the electronic device 1000 and the display module 200 are both in a folded state, with the display module 200 located inside the electronic device 100. The first display portion 213 and the second display portion 214 are positioned opposite each other, and the foldable portion 215 is bent. At this time, the exposed area of the display module 200 is relatively small, which greatly reduces the probability of damage to the display module 200 and effectively protects it.
[0068] As shown in Figure 2, the electronic device 1000 and the display module 200 are in a flattened state. The first display portion 213 and the second display portion 214 are relatively flattened, and the foldable portion 215 is flattened without bending. At this time, the included angle between any two of the first display portion 213, the second display portion 214, and the foldable portion 215 can be 180 degrees. The display module 200 has a large display area, realizing a large-screen display of the electronic device 1000 and improving the user experience.
[0069] It should be understood that the electronic device 1000 shown in this application is an electronic product that can only be folded inwards. In some other embodiments, the electronic device 1000 may also be an electronic product that can only be folded outwards, or the electronic device 1000 may also be an electronic product that can be folded both inwards and outwards, that is, the electronic device 1000 shown in this application is an electronic device that can rotate 360 degrees, and this application does not impose any specific limitations on this.
[0070] The folding portion 212 is electrically connected to the display portion 211 and folds relative to the display portion 211, and is disposed on the non-display surface 2112. Specifically, the folding portion 212 is disposed between the first display portion 213 and the middle frame 11 of the first main body 110, and is connected to the end of the first display portion 213 away from the pivot mechanism 130 and the foldable portion 215, and folds relative to the first display portion 213. It should be noted that "the folding portion 212 is disposed on the non-display surface 2112" means that the folding portion 212 is disposed on the side where the non-display surface 2112 of the display portion 211 is located. The folding portion 212 can be directly disposed on the non-display surface 2112, or the folding portion 212 can be indirectly disposed on the non-display surface 2112. For example, the folding portion 212 can be disposed on the non-display surface through a layer structure such as adhesive. Similar descriptions in the following text can be understood in the same way.
[0071] A connecting circuit board 220 is disposed on the non-display surface 2112 and is electrically connected to the folding portion 212. Specifically, the connecting circuit board 220 is disposed between the first display portion 213 and the middle frame 11 of the first main body 110, and overlaps the end of the folding portion 212 facing the foldable portion 215 to form a bonding area (not shown in the figure). The connecting circuit board 220 may be a flexible printed circuit board (FPC).
[0072] The display device 230 is disposed on the side of the connecting circuit board 220 opposite to the display panel 210 and is electrically connected to the connecting circuit board 220 to achieve electrical connection with the processor through the connecting circuit board 220. Specifically, the display device 230 is disposed on the edge of the connecting circuit board 220 and can pass through the second clearance hole 11b and clearance groove 11c of the middle frame 11. In other words, both the second clearance hole 11b and the clearance groove 11c can avoid the display device 230. The display device 230 and the bottom wall of the clearance groove 11c are spaced apart to avoid interference between the display device 230 and the middle frame 11. For example, the display device 230 may include a display driver, such as a display driver IC (DDIC), or the display device 230 may include a touch driver, such as a touch panel IC (TPIC), or the display device 230 may include a flash memory IC.
[0073] It should be noted that the second clearance hole 11b and clearance groove 11c on the middle frame 11 are both used to avoid the display device 230. The display device 230 can reuse the thickness space of the second clearance hole 11b and clearance groove 11c, reducing the thickness of the first main body 110 and helping to achieve a thinner and lighter design of the electronic device 1000. Moreover, the design of the clearance groove 11c can reduce the area of the hole on the middle frame 11, ensuring the overall strength of the middle frame 11 and helping to improve the reliability of the electronic device 1000.
[0074] In this embodiment, the reinforcing member 30 is a non-planar structure, and the cover portion 31 has 3D structural features such as bending. The reinforcing member 30 has a large horizontal area and three-dimensional strength, which can further enhance the stress in weak parts such as the narrow strip portion 23 in the circuit board 20, effectively reinforcing the circuit board 20, preventing the narrow strip portion 23 from breaking, and ensuring that the first antenna feed line 50 stably feeds the first radiator 116 from the antenna base 40 along the narrow strip portion 23, thus ensuring the reliability of the electronic device 1000.
[0075] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
