Description

Technical Field

[0001] This application relates to the field of electronic product technology, and more particularly to an electronic device with a foldable screen. Background Technology

[0002] Currently, foldable screens are widely used in mobile terminals, such as foldable phones and foldable tablets. These mobile terminals mainly consist of two shells connected by a hinge structure to enable the foldable screen to be unfolded and closed.

[0003] for example, Figure 1 A partial structural diagram of a mobile terminal is given. Figure 1 In this configuration, the first housing 011 is rotatably connected to the second housing 012 via a pivot structure 02. The foldable screen 07 is positioned on one side of the first housing 011, the pivot structure 02, and the second housing 012. When the first housing 011 and the second housing 012 rotate relative to or away from each other under the action of the pivot structure 02, the foldable screen 07 can be folded. For example, in... Figure 1 In this process, when the first housing 011 rotates towards each other along the P1 direction and the second housing 012 rotates towards each other along the P2 direction, the folding screen 07 can switch from the flat state to the closed state.

[0004] Generally, the first housing 011 and the second housing 012 are respectively provided with electronic devices with different functions, for example, in Figure 1 In this case, a printed circuit board (PCB) 03 is disposed on the first housing 011, and a battery 04 is disposed on the second housing 012. The printed circuit board 03 needs to be electrically connected to the battery 04. Currently, a flexible printed circuit board (FPC) 05 is often used as the electrical connection structure to realize the interconnection between the printed circuit board 03 and the battery 04.

[0005] During the folding process of the foldable screen 07, the flexible circuit board 05 needs to be repeatedly bent in conjunction with the hinge structure 02. Therefore, the requirements for the bendable lifespan of the flexible circuit board 05 are relatively high. In order to improve the service life of the flexible circuit board 05, the shape of the flexible circuit board 05 during bending is also required and is controllable.

[0006] In existing technologies, such as Figure 1As shown, the two ends of the flexible circuit board 05 closest to the first housing 011 and the second housing 012 are respectively fixed to the corresponding housings by reinforcing plates 06. In addition, another reinforcing plate 06 is provided in the bending area of ​​the flexible circuit board 05 located between the first housing 011 and the second housing 012. That is to say, during the folding process of the folding screen 07, the shape of the flexible circuit board 05 can be maintained by the three reinforcing plates 06, so that the bending trend of the flexible circuit board 05 is controllable.

[0007] As the size of mobile terminals decreases, the required length needs to be shortened. Figure 1 The dimension along the L direction of the flexible circuit board 05, and the bending shape therein, are constantly decreasing, thus causing the distance S between the first housing 011 and the second housing 012 to continuously decrease. However, the dimension along the L direction of the flexible circuit board 05, and the bending shape, remain basically unchanged. So, how can... Figure 1 As the dimensions in the L direction continue to shrink, maintaining the bending shape of the bending area of ​​the flexible circuit board 05 remains essentially unchanged is a pressing issue that needs to be addressed. Summary of the Invention

[0008] This application provides an electronic device. The main objective is to provide an electronic device that can maintain a substantially unchanged bending shape in the bending region of the flexible circuit board located between the two housings when the distance between the two housings is reduced.

[0009] To achieve the above objectives, the embodiments of this application adopt the following technical solutions:

[0010] This application provides an electronic device, which is a foldable electronic device with a flexible screen, such as a foldable screen mobile phone, a foldable screen tablet, etc.

[0011] The electronic device includes a first housing and a second housing, a pivot structure, and a flexible circuit board. The first housing and the second housing are located on opposite sides of the pivot structure and can rotate towards each other via the pivot structure, allowing the electronic device to switch from a flattened state to a closed state. The first housing includes a first surface and a second surface facing each other, one of which supports the flexible screen. Thus, the pivot structure enables the electronic device to switch between a closed state and a flattened state. Furthermore, a first mounting surface is formed at the end of the first housing near the pivot structure, and a second mounting surface is formed at the end of the second housing near the pivot structure. Both the first and second mounting surfaces are inclined surfaces relative to the first surface. A portion of the flexible circuit board is fixed to the first mounting surface to form a first fixing part; another portion of the flexible circuit board is fixed to the second mounting surface to form a second fixing part; the portion of the flexible circuit board located between the first and second fixing parts is bent to form a bent part, which can bend when the first housing and the second housing rotate towards each other.

[0012] In the electronic device disclosed in this application, since the first fixing part of the flexible circuit board can be electrically connected to the electronic device on the first housing, and the second fixing part can be electrically connected to the electronic device on the second housing, an electrical connection between the electronic device on the first housing and the electronic device on the second housing can be achieved. Furthermore, when the first housing and the second housing rotate towards each other under the drive of the rotating shaft structure, the bent portion of the flexible circuit board located between the first housing and the second housing will also bend in coordination with the rotating shaft structure, so that the electronic device on the first housing and the electronic device on the second housing are in a stable electrical connection relationship.

[0013] Furthermore, the first and second housings provided in this application each have a first mounting surface for fixing a first fixing portion of the flexible circuit board and a second mounting surface for fixing a second fixing portion of the flexible circuit board. In other words, the portions of the flexible circuit board located at both ends of the bent portion are fixed to the first and second housings. This allows the bending shape of the bent portion of the flexible circuit board to be controlled when the first and second housings rotate, making the bending trend of the flexible circuit board controllable rather than arbitrary.

[0014] In addition, both the first mounting surface for fixing the first fixing part and the second mounting surface for fixing the second fixing part are inclined surfaces. It can be understood that the inclined surfaces here are inclined relative to the surface of the first housing used to support the flexible screen. Compared with setting these two mounting surfaces to be parallel to the surface of the first housing used to support the flexible screen, the space occupied between the first housing and the second housing can be reduced while maintaining the bending shape of the bending part basically unchanged. It can also be explained that when the distance between the first housing and the second housing becomes smaller, by setting the first mounting surface and the second mounting surface to be inclined, the length of the bending part of the flexible circuit board can be kept basically unchanged, and the bending shape can also be kept basically unchanged, so as to adapt to the miniaturization design of electronic devices.

[0015] In one possible implementation, the electronic device further includes: a first reinforcing plate and a second reinforcing plate; the first reinforcing plate is fixed to a first mounting surface, and a first fixing part is fixed to the first reinforcing plate; the second reinforcing plate is fixed to a second mounting surface, and a second fixing part is fixed to the second reinforcing plate.

[0016] By fixing the first fixing part to the first reinforcing plate and the first reinforcing plate to the first mounting surface, and by fixing the second fixing part to the second reinforcing plate and the second reinforcing plate to the second mounting surface, the morphological stiffness of the entire flexible circuit board can be improved, the resistance to deformation can be enhanced, and the connection strength between the flexible circuit board and the first and second housings can be strengthened.

[0017] In one possible implementation, when the first housing and the second housing rotate toward each other, the first surface moves closer to the second housing relative to the second surface; along the direction from the second surface to the first surface, the first mounting surface is inclined from the first housing toward the direction closer to the rotating shaft structure, and the second mounting surface is inclined from the second housing toward the direction closer to the rotating shaft structure.

[0018] This embodiment can be understood as follows: when electronic devices are disposed on the second surface of the first housing, and electronic devices are also disposed on a surface of the second housing that is on the same side as the second surface of the first housing, the first mounting surface can be tilted from the first housing toward the direction closer to the pivot structure along the direction from the second surface to the first surface, and the second mounting surface can be tilted from the second housing toward the direction closer to the pivot structure. This shortens the path from the flexible circuit board to the electronic devices on the first housing, facilitating electrical connection between the electronic devices on the first housing and the flexible circuit board. Similarly, the path from the flexible circuit board to the electronic devices on the second housing can also be shortened, facilitating electrical connection between the electronic devices on the second housing and the flexible circuit board.

[0019] In one possible implementation, when the first housing and the second housing rotate toward each other, the first surface is closer to the second housing than the second surface; along the direction from the second surface to the first surface, the first mounting surface is inclined from the first housing toward the direction closer to the rotating shaft structure, and the second mounting surface is inclined from the second housing toward the direction closer to the rotating shaft structure; furthermore, when the electronic device is in a flattened state, the portion of the bent part near the first fixing part and the portion of the bent part near the second fixing part both protrude toward the first surface.

[0020] This allows the first and second fixing parts to smoothly transition to the bending part, enhancing the morphological rigidity and deformation resistance of the flexible circuit board.

[0021] In one possible implementation, the electronic device further includes a circuit board disposed on a first housing, on which a first electronic device is disposed, and a second electronic device is disposed on a second housing; a portion of the flexible circuit board is connected to a first fixing part and extends to the first housing, and is electrically connected to the first electronic device; another portion of the flexible circuit board is connected to a second fixing part and extends to the second housing, and is electrically connected to the second electronic device.

[0022] In other words, the flexible circuit board includes not only a first fixing part fixed on the first housing, a second fixing part fixed on the second housing, and a bending part located between the first housing and the second housing, but also a first extension part laid on the first housing and a second extension part laid on the second housing. In this way, when the first housing and the second housing rotate, the first extension part will rotate with the first housing, and the second extension part will also rotate with the second housing. The first fixing part and the second fixing part are used to limit the bending direction of the bending part.

[0023] In one possible implementation, the bent portion is fixed to the pivot structure.

[0024] In one possible implementation, when the electronic device is in the flattened state, the bending portion includes a first protrusion and a second protrusion that protrude toward the second surface, and a connecting portion located between the first protrusion and the second protrusion, connecting the first protrusion and the second protrusion and protruding toward the first surface; the connecting portion is fixed to the rotating shaft structure.

[0025] Since this embodiment includes adjacent first and second protrusions, the connecting portion located between the first and second protrusions can be fixed to the rotating shaft structure. Therefore, the bending direction of the portion of the flexible circuit board located between the first fixing portion and the connecting portion can be controlled by the fixed first fixing portion and the fixed connecting portion. Similarly, the bending direction of the portion of the flexible circuit board located between the second fixing portion and the connecting portion can be controlled by the fixed second fixing portion and the fixed connecting portion. Thus, the bending direction of the entire flexible circuit board can be controlled.

[0026] In one possible implementation, the electronic device further includes a third reinforcing plate, which is parallel to the first surface; the third reinforcing plate is fixed to the rotating shaft structure, and the connecting part is fixed to the third reinforcing plate.

[0027] In other words, a third reinforcing plate is used to fix the connecting part of the flexible circuit board to the rotating shaft structure, thereby enhancing the connection strength between the connecting part and the rotating shaft structure and further improving the morphological rigidity of the entire flexible circuit board.

[0028] In one possible implementation, when the electronic device is in the flattened state, the bent portion includes a protrusion that bulges toward the second surface.

[0029] In one possible implementation, the electronic device further includes a waterproof structure, and the flexible circuit board includes a third fixing part connected to the first fixing part and located away from the bending part, the gap between the third fixing part and the first housing being filled by the waterproof structure.

[0030] In other words, the third fixing part of the flexible circuit board near the first fixing part is connected to the first housing through a waterproof structure to prevent water between the first housing and the second housing from entering the first housing and affecting the performance of the electronic devices in the first housing.

[0031] Furthermore, since the first mounting surface of the first fixing part is set on an inclined plane, more space can be provided for the waterproof structure compared to a horizontal plane, increasing the size of the first waterproof structure and thus improving the waterproof performance of the electronic device.

[0032] In one possible implementation, the first housing has a first through hole that passes through the first surface and the second surface; a first mounting surface is formed on the side wall of the first through hole away from the second housing, and a third mounting surface connected to the first mounting surface is also formed on the side wall of the first through hole forming the first mounting surface, the third mounting surface being parallel to the first surface; a waterproof structure is formed on the third mounting surface, and a third fixing part is fixed to the waterproof structure; a portion of the flexible circuit board passes sequentially from the first surface through the first mounting surface of the first through hole and the third mounting surface to the second surface.

[0033] In other words, a first through hole can be made in the first housing for the bending portion to pass through, so as to make full use of the first housing and make the structure of the entire electronic device more compact and smaller.

[0034] In one possible implementation, the electronic device further includes a pressure plate structure; the pressure plate structure is fixed to the first housing and extends partially into the first through hole, pressing the first fixing part onto the first mounting surface and pressing the third fixing part onto the third mounting surface.

[0035] Specifically, the clamping force of the pressure plate structure on the first fixing part increases the connection strength between the first fixing part and the first housing, further improving the controllability of the bending direction of the bending part. Furthermore, the clamping force of the pressure plate structure on the third fixing part enhances the waterproofing effect of the waterproof structure.

[0036] In one possible implementation, the pivot structure includes opposing fifth and sixth surfaces, with the fifth surface and the first surface located on the same side; the pivot structure forms a second through hole penetrating the fifth and sixth surfaces; at least a portion of the bent portion passes through the second through hole from the fifth surface to the sixth surface.

[0037] The above embodiments describe the possibility of opening a first through hole in the first housing for the portion of the bent part near the first fixing part to pass through. In this embodiment, a second through hole is opened in the pivot structure for the portion of the bent part opposite to the pivot structure to pass through. The resulting flexible circuit board can be called a through-axis wiring structure to make full use of the space occupied by the pivot structure.

[0038] In one possible implementation, the tilt angle of the first mounting surface relative to the first surface is 15° to 75°.

[0039] In one possible implementation, the electronic device further includes a flexible screen; the flexible screen is disposed on the same side of the first housing, the second housing, and the pivot structure; and a portion of the flexible screen is fixed to the first housing and the second housing.

[0040] In this way, when the first and second housings rotate relative to each other, the flexible screen can switch between a closed state and a flattened state. Attached Figure Description

[0076] This application provides a foldable electronic device. The foldable electronic device can include various electronic devices with a flexible screen and capable of changing the unfolded or folded form of the flexible screen and itself. Under different usage requirements, the foldable electronic device can be unfolded to a flattened state, folded to a closed state, or in an intermediate state between the flattened and closed states. That is, the foldable electronic device has at least two states: a flattened state and a closed state. In some cases, it may further include a third state, namely, an intermediate state between the flattened and closed states. It is understood that the intermediate state is not a unique state, but can be any one or more states between the flattened and closed states of the electronic device.

[0077] For example, foldable electronic devices can be, but are not limited to, mobile phones, tablets, laptops, e-book readers, cameras, wearable devices, and home electronic devices. For ease of understanding, in the embodiments of this application, foldable electronic devices are described using mobile phones as an example.

[0078] Reference Figure 2 , Figure 2 An exploded view of a foldable electronic device 100 provided in an embodiment of this application, as shown below. Figure 2 As shown, the foldable electronic device 100 may include a hinge structure 02, a first housing 011, a second housing 012, and a flexible screen 07.

[0079] The first housing 011 and the second housing 012 are disposed on opposite sides of the rotating shaft structure 02 and are respectively connected to the rotating shaft structure 02. The rotating shaft structure 02 is movable, so that the first housing 011 and the second housing 012 are folded or unfolded relative to each other. Here, the first housing 011 can also be referred to as the first middle frame, and similarly, the second housing 012 can also be referred to as the second middle frame.

[0080] Continue to refer to Figure 2 The flexible screen 07 can continuously cover the first housing 011 and the second housing 012 of the foldable electronic device 100, as well as the same side of the hinge structure 02. Furthermore, part of the flexible screen 07 can be fixed to the first housing 011, and another part can be fixed to the second housing 012. In this way, when the first housing 011 and the second housing 012 move relative to or away from each other, the flexible screen 07 can be folded or flattened.

[0081] The flexible screen 07 can be used to display information and provide an interactive interface for users. In various embodiments of this application, the flexible display screen 07 may include, but is not limited to, an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode (AMOLED) display screen, a mini organic light-emitting diode (MLED) display screen, a micro organic light-emitting diode (MOLED) display screen, a quantum dot light-emitting diode (QLED) display screen, etc.

[0082] As mentioned above, the electronic device 100 can switch between a flattened state and a closed state by the movement of the pivot structure 02, and the flexible screen 07 can be folded or unfolded along with the first housing 011 and the second housing 012.

[0083] Typically, foldable electronic devices fold in two ways: outward folding and inward folding. Outward folding means that during the transition from a flat to a closed state, and also when the device is closed, the flexible screen 07 remains on the outside of the device. This means that the flexible screen 07 is still visible to the user during the folding process and when closed, and the user can still perform some operations on the flexible screen 07 when it is closed. For example, ... Figure 2 As shown, when the first housing 011 rotates along the P1 direction and the second housing 012 rotates along the P2 direction, the flexible screen 07 is located outside the electronic device 100. Such an electronic device 100 can be called an outward-folding electronic product.

[0084] Conversely, an inward-folding design means that during the transition from a flattened to a closed state of the electronic device, and while the device is closed, the flexible screen 07 remains inside the electronic device 100. In other words, the flexible screen 07 gradually becomes invisible to the user during the folding process, until it is completely hidden between the two housings in the closed state. For example, as... Figure 3 The electronic device 100 shown, Figure 3The exploded view of a foldable electronic device 100 provided in an embodiment of this application shows that when the first housing 011 rotates along the P1 direction and the second housing 012 rotates along the P2 direction, the flexible screen 07 is located inside the electronic device 100. Until the closed state, the flexible screen 07 is housed between the two housings and completely hidden. Such an electronic device 100 can be called an inward-folding electronic product.

[0085] Whether Figure 2 The outward-folding electronic device 100 shown is still... Figure 3 The inward-folding electronic device 100 shown can have either the first housing 011 or the second housing 012 forming an installation space for mounting electronic components such as circuit boards, batteries, receivers, speakers, and cameras. The circuit board can integrate electronic components such as the main controller, storage unit, antenna module, and power management module, while the battery powers the flexible screen 07, circuit board, receiver, speaker, and camera. Figure 4 As shown, Figure 4 An exploded view of a foldable electronic device 100 provided in an embodiment of this application. Figure 4 The structure shown illustrates that a circuit board 03, such as a printed circuit board (PCB), can be installed in the mounting space of the first housing 011, and a battery 04 can be installed in the mounting space of the second housing 012. Alternatively, other types of electronic devices can be installed on the first housing 011 and the second housing 012 respectively. For ease of description, the electronic device installed on the first housing 011 can be referred to as the first electronic device, and the electronic device installed on the second housing 012 can be referred to as the second electronic device.

[0086] Therefore, in order for battery 04 to supply power to circuit board 03, an electrical connection structure is needed that spans between the first housing 011 and the second housing 012. Furthermore, since the first housing 011 and the second housing 012 need to move repeatedly relative to or away from each other during use, a flexible electrical connection structure with bending sections is required. For example, a flexible printed circuit board (FPC) could be used. Figure 4 The diagram shows one possible structure for the flexible circuit board 05.

[0087] With the miniaturization design of electronic devices 100, such as Figure 4As shown, the dimensions of the electronic device 100 along the L direction gradually decrease, so that the space for accommodating the flexible circuit board 05 located between the first housing 011 and the second housing 012 also continuously decreases. However, the bending shape of the flexible circuit board 05 cannot be changed. For example, the radius of curvature of the bending portion of the flexible circuit board 05 cannot be reduced simply because the dimensions between the first housing 011 and the second housing 012 along the L direction decrease. If the radius of curvature of the bending portion is reduced, the bending life of the bending portion will be severely shortened under repeated folding of the first housing 011 and the second housing 012, and it may even lead to failure of the electrical connection performance of the flexible circuit board 05.

[0088] Based on the aforementioned situation where the space for accommodating the flexible circuit board 05 located between the first housing 011 and the second housing 012 is continuously decreasing, this application provides a novel structure for arranging the flexible circuit board 05. Therefore, even if the dimensions of the electronic device 100 along the L direction gradually decrease, this arrangement structure will not substantially change the bending shape of the bent portion of the flexible circuit board 05. The relevant structure will be described in detail below.

[0089] Figure 5 A simplified diagram of a partial structure of an electronic device 100 according to an embodiment of this application is provided. Figure 5 It can be along Figure 3 A simplified diagram obtained by sectioning along the AA direction. Figure 6 yes Figure 5 Explosion diagram, Figure 7 A simplified diagram of a partial structure of another electronic device 100 according to an embodiment of this application is provided. Figures 5 to 7 In the structure shown, the pivot structure 02 located between the first housing 011 and the second housing 012 is omitted. (Combined) Figure 5 , Figure 6 and Figure 7 The diagram shows a portion of the first housing 011, a portion of the second housing 012, and a portion of the flexible circuit board 05 of the electronic device 100 of this application. The first housing 011 has a first mounting surface M1 formed at one end near the pivot structure 02, and the second housing 012 has a second mounting surface M2 formed at one end near the pivot structure 02. Both the first mounting surface M1 and the second mounting surface M2 are inclined surfaces; for example, both the first mounting surface M1 and the second mounting surface M2 can be inclined planes.

[0090] like Figure 5 and Figure 6As shown, the first housing 011 has opposing first surfaces A1 and B1, and the second housing 012 has opposing third surfaces A2 and B2. First surfaces A1 and third surfaces A2 are located on the same side, and second surfaces B1 and fourth surfaces B2 are located on the same side. The flexible screen 07 can be disposed on one side of the first surfaces A1 and third surfaces A2. Thus, when the first housing 011 conforms to… Figure 5 Rotating in the direction of P1 as shown, the second housing 012 follows... Figure 5 When rotated in the direction of P2, the resulting electronic device is an inwardly folding electronic device; or, in some other alternative implementations, the flexible screen 07 can be set on one side of the second surface B1 and the fourth surface B2.

[0091] The tilting arrangement of the first mounting surface M1 and the second mounting surface M2 can be understood as follows: Figure 5 and Figure 6 One arrangement of the first mounting surface M1 and the second mounting surface M2 is given, namely, along the direction from the second surface B1 to the first surface A1 (that is... Figure 5 and Figure 6 (As shown in the T1 direction), the first mounting surface M1 is inclined from the first housing 011 toward the direction closer to the rotating shaft structure 02, and the second mounting surface M2 is inclined from the second housing 012 toward the direction closer to the rotating shaft structure 02. Additionally, Figure 7 Another configuration of the first mounting surface M1 and the second mounting surface M2 is given, namely, along the direction from the first surface A1 to the second surface B1 (that is... Figure 7 The T2 direction shown is related to... Figure 6 (in the opposite direction of T1 in the middle), the first mounting surface M1 is inclined from the first housing 011 toward the direction close to the rotating shaft structure 02, and the second mounting surface M2 is inclined from the second housing 012 toward the direction close to the rotating shaft structure 02.

[0092] In other words, neither the first mounting surface M1 nor the second mounting surface M2 provided in this application are parallel to the first surface A1 or the second surface B1, but rather are surfaces with an angle that is not equal to zero relative to the first surface A1 or the second surface B1.

[0093] Continue to combine Figure 5 , Figure 6 and Figure 7 A portion of the flexible circuit board 05 is arranged in a direction parallel to the first mounting surface M1 and fixed on the first mounting surface M1 to form Figure 6 The first fixing part Q1 is shown; another part of the flexible circuit board 05 is arranged in a direction parallel to the second mounting surface M2 and fixed on the second mounting surface M2 to form a... Figure 6 The second fixing part Q2 shown; and the portion of the flexible circuit board 05 located between the first fixing part Q1 and the second fixing part Q2 is bent to form Figure 6 The bending section Q3 is shown.

[0094] Combination Figure 8 ,introduce Figure 5 and Figure 6 The bending process of the flexible circuit board 05 during the transition of the electronic device from a flattened state to a closed state is shown. Figure 8 The first housing 011 rotates along the P1 direction, and the second housing 012 rotates along the P2 direction. Since the first fixing part Q1 is fixed to the first mounting surface M1, the first fixing part Q1 can rotate synchronously with the first housing 011. Similarly, since the second fixing part Q2 is fixed to the second mounting surface M2, the second fixing part Q2 can also rotate synchronously with the second housing 012. Therefore, compared to... Figures 5 to 8 The structural diagrams of the two different states shown indicate that during the continuous rotation of the first housing 011 and the second housing 012, the first fixing part Q1 and the second fixing part Q2 cause the bending shape of the bending part Q3 to change continuously, that is, the radius of curvature of the bending part Q3 gradually increases, and finally the bending part Q3 cooperates with the rotating structure to realize the closure of the electronic device.

[0095] in addition, Figure 9 A simplified diagram of another part of the structure of an electronic device 100 according to an embodiment of this application is also provided. Figure 9 The illustrated embodiments and the above Figure 5 and Figure 6 The embodiment shown is the same in that the first mounting surface M1 for fixing the first fixing part Q1 and the second mounting surface M2 for fixing the second fixing part Q2 are both inclined surfaces. Figure 9 The illustrated embodiments and the above Figure 5 and Figure 6 The difference in the illustrated embodiment is that when the electronic device is in a flattened state, Figure 5 and Figure 6 The bent portion Q3 includes a protrusion that bulges toward the second surface B1; however, in Figure 9 In the case of the electronic device being in a flattened state, the bending part Q3 includes two protrusions protruding toward the second surface B1, namely the first protrusion Q31 and the second protrusion Q32.

[0096] Among other alternative implementation methods, it is possible to Figure 9 Based on this, more protrusions are provided. This application does not impose special limitations on the number of protrusions or the radius of curvature of the bent portion Q3.

[0097] Combined again Figure 5 , Figure 6 and Figure 9When the electronic device is in a flattened state, the portion of the bent part Q3 near the first fixing part Q1 and the portion of the bent part Q3 near the second fixing part Q2 both protrude towards the first side A1. In this way, the first fixing part Q1 can smoothly transition to the bent part Q3, and similarly, the second fixing part Q2 can also smoothly transition to the bent part Q3.

[0098] Based on the above Figure 5 , Figure 6 , Figure 7 and Figure 8 ,as well as Figure 9 The description of the method by which the flexible circuit board 05 is fixed on the first housing 011 and the second housing 012 shows that, compared with the prior art, the mounting surfaces of the first fixing part Q1 and the second fixing part Q2 used to fix the flexible circuit board 05 are... Figure 1 The mounting surface of this application is an inclined surface, as described below. Figure 10a and Figure 10b Explain how, when the first fixing part Q1 and the second fixing part Q2 of the flexible circuit board 05 are fixed with inclined surfaces, the bending shape of the bending part Q3 of the flexible circuit board 05 remains basically unchanged even as the size of the electronic device 100 along the L direction gradually decreases.

[0099] like Figure 10a As shown, Figure 10a The diagram shown illustrates a structural method for fixing a flexible circuit board in the prior art. Figure 10b This diagram illustrates a structural method for fixing the flexible circuit board according to this application. Figure 10b In this configuration, the first mounting surface M1 is tilted at an angle of 45° relative to the first surface A1, and the second mounting surface M2 is tilted at an angle of -45° relative to the first surface A1. For example... Figure 10a When the S1 dimension of the horizontal mounting surface of the first fixing part Q1 along the L direction is 2mm, corresponding to Figure 10b Only the S2 dimension of the inclined first mounting surface M1 along the L direction needs to be 1.414mm to maintain the presence of two protrusions between the first housing 011 and the second housing 012, and the radius of curvature of each protrusion remains basically unchanged. In other words, the bending shape of the bent portion between the first housing 011 and the second housing 012 can remain basically unchanged.

[0100] In addition, due to Figure 10a The horizontal mounting surface was changed to Figure 10b The inclined mounting surface, and therefore, the starting point of the arc transition from the first fixing part Q1 to the bending part Q3 will be from... Figure 10a Move position C1 to Figure 10bAt position C2, the corresponding movement S4 of the arc-starting tangent point is 1.3mm. In this way, the first housing 011 can be... Figure 10a The position moves along the L direction by S3 = 1.886 mm, thus moving to... Figure 10b Similarly, the second housing 012 will also be moved by S3 = 1.886 mm. In this way, the dimensions of the entire electronic device along the L direction can be reduced by 3.772 mm.

[0101] From another perspective, compared to existing technologies, when the dimensions of the first housing 011 and the second housing 012 along the L direction remain unchanged, if the present application is adopted... Figure 10b The flexible circuit board fixing method can save 3.772mm in size, which can make room for other structural components. For example, the size of the waterproof structure can be increased to improve the waterproof performance of the electronic device; or the size of the battery can be increased to increase the battery capacity; or the size of the circuit board can be increased to set more electronic components on the circuit board to meet the high configuration performance requirements of the electronic device.

[0102] In addition, since both ends of the flexible circuit board 05 located between the first housing 011 and the second housing 012 are fixed to the corresponding housing structure, the flexible circuit board 05 will not shift left or right along the L direction. After multiple bends, the consistency of the shape is significantly improved, and the life benefit of the flexible circuit board is also significantly improved.

[0103] The electronic device 100 provided in this application may also include a reinforcing plate. For example, in Figure 5 and Figure 6 The structure includes a first reinforcing plate 061 and a second reinforcing plate 062. The first reinforcing plate 061 is fixed to the first mounting surface M1, and the first fixing part Q1 is fixed to the first reinforcing plate 061. That is, the first fixing part Q1 is fixed to the first mounting surface M1 through the first reinforcing plate 061. Similarly, the second reinforcing plate 062 is fixed to the second mounting surface M2, and the second fixing part Q2 is fixed to the second reinforcing plate 062.

[0104] Because in Figure 5 and Figure 6 In the flexible circuit board 05 shown, the bending portion Q3 includes only one protrusion protruding towards the second side B1. Therefore, when the first housing 011 and the second housing 012 rotate relative to each other, the bending tendency of the bending portion Q3 can be constrained by the first reinforcing plate 061 and the second reinforcing plate 062, thereby improving the morphological stiffness of the flexible circuit board 05 and enhancing the deformation resistance of the bending portion Q3. As a result, the bending portion Q3 can maintain its initial shape and not deform after being bent multiple times.

[0105] Combined Figure 9 and Figure 10b , Figure 9 and Figure 10b The bent portion Q3 shown includes a first protrusion Q31 and a second protrusion Q32, which are connected by a connecting portion Q33, and the connecting portion Q33 protrudes towards the first side surface A1. Therefore, as described above... Figure 5 and Figure 6 In comparison, in addition to the first reinforcing plate 061 and the second reinforcing plate 062, a third reinforcing plate 063 is also included. The third reinforcing plate 063 can be fixed to the rotating shaft structure 02, and the connecting part Q33 is fixed to the third reinforcing plate 063. Here, the third reinforcing plate 063 is parallel to the first side A1 of the first housing 011. With this design, the first reinforcing plate 061 and the third reinforcing plate 063 can constrain the bending trend of the part between the first fixing part Q1 and the connecting part Q33, and the second reinforcing plate 062 and the third reinforcing plate 063 can constrain the bending trend of the part between the second fixing part Q2 and the connecting part Q33. Finally, the three reinforcing plates can constrain the bending trend of the entire bending part Q3, improve the morphological rigidity of the entire flexible circuit board 05, and enhance the deformation resistance of the bending part Q3.

[0106] Based on the above description of the different forms of the bending portion Q3 of the flexible circuit board 05, it can be considered that when the bending portion Q3 includes... Figure 9 When there are two or more protrusions as shown, part of the bending part 03 can be fixed on the rotating shaft structure 02 so that when the electronic device is flattened or closed, the bending trend of the bending part Q3 is constrained, so that the bending trend of the bending part Q3 can be controlled.

[0107] The reinforcing plate involved in this application can be sheet material, such as steel plate; or it can be glass fiber epoxy resin copper clad laminate, which can be called FR-4 material; or other materials can be used. This application does not impose any special restrictions on the materials that can be selected for the reinforcing plate.

[0108] In some alternative implementations, an adhesive layer can be used to fix the flexible circuit board to the reinforcing plate. For example, pressure-sensitive adhesive (PSD) can be used to fix the reinforcing plate and the flexible circuit board together. Since PSD is an adhesive that is sensitive to pressure, it allows the flexible circuit board to have enhanced length self-adaptation capability when bent.

[0109] In the electronic device 100 provided in this application embodiment, a gap will be formed at the joint of the first middle frame 011 and the second middle frame 012 (e.g. Figure 3The R region in the gap will then become a path for liquid (e.g., water) to enter the electronic device 100. Figure 11 The diagram illustrates the transport path of water flowing in from gap R, as shown below. Figure 11 As shown by the dashed line with arrows, in order to prevent water from entering the electronic components of the first housing 011 and the electronic components of the second housing 012, the electronic device provided in this application may also include a waterproof structure 11. The waterproof structure 11 can be installed in various ways, and the installation position and structure of the waterproof structure 11 will be described below.

[0110] Figure 11 In the given implementation, the flexible circuit board 05 includes a third fixing part Q4 connected to the first fixing part Q1 and located away from the bending part Q3. The gap between the third fixing part Q4 and the first housing 011 is filled by a waterproof structure 11. In this way, water flowing in from the gap R will not enter the electronic components of the first middle frame 011 due to the blocking effect of the waterproof structure 11, thereby also protecting the electronic components.

[0111] In addition, the flexible circuit board 05 also includes a fourth fixing part Q5 connected to the second fixing part Q2 and located away from the bending part Q3. In order to prevent water flowing in from the gap R into the electronic components of the second middle frame 012, the gap between the fourth fixing part Q5 and the first housing 011 is also filled by the waterproof structure 11 to prevent water from entering the electrical components of the second middle frame 012, thereby improving the waterproof performance of the entire electronic device.

[0112] Furthermore, since the first mounting surface M1 of the first fixing part Q1 is an inclined surface, when the size of the electronic device 100 in the L direction given in this application is equal to the size of the existing electronic device 100 in the L direction, the inclined mounting surface can provide more space for the waterproof structure 11, thereby increasing the size of the waterproof structure 11 in the L direction and improving the waterproof performance of the electronic device.

[0113] Continue to refer to Figure 11 A third mounting surface M3 is also formed on the first middle frame 011. The third mounting surface M3 is connected to the first mounting surface M1, and the third mounting surface M3 is parallel to the first surface A1. The waterproof structure 11 is fixed in the gap formed between the third mounting surface M3 and the third fixing part Q4 of the flexible circuit board 05. In this way, while achieving the waterproof effect, the flexible circuit board 05 can be smoothly extended from the first fixing part Q1 to the first middle frame 011.

[0114] The waterproof structure 11 set on the second middle frame 012 can be set in the same way as the waterproof structure 11 set on the first middle frame 011, and will not be described again here.

[0115] Figure 12 An exploded structural diagram of an electronic device 100 according to this application is provided, see [link / details]. Figure 12 As shown, the electronic device 100 includes not only the aforementioned flexible circuit board 05, hinge structure 02, and first housing 011 and second housing 012 disposed on opposite sides of the hinge structure 02, but may also include a cover 08. The cover 08 is fixedly connected to the hinge structure 02. When the electronic device 100 is in a flattened state, the hinge structure 02 and the cover 08 are hidden between the first housing 011 and the second housing 012 and are not visible to the user. However, when the electronic device 100 switches from a flattened state to a closed state, the cover 08 gradually becomes visible, which not only protects the hinge structure 02 but also enhances the overall aesthetics of the electronic device 100.

[0116] Figure 13 yes Figure 12 The diagram shows the structure of the flexible circuit board 05. In addition to the first fixing part Q1, the second fixing part Q2, the bending part Q3, the third fixing part Q4, and the fourth fixing part Q5, the flexible circuit board 05 may also include a first extension part Q6 connected to the third fixing part Q4 and a second extension part Q7 connected to the fourth fixing part Q5. Figure 13 The Q in the design includes a first fixing part Q1, a second fixing part Q2, a bending part Q3, a third fixing part Q4, and a fourth fixing part Q5.

[0117] Combination Figure 12 and Figure 13 The first extension Q6 can extend to the first housing 011 and be electrically connected to a first electronic device disposed on the first housing 011. Similarly, the second extension Q7 can extend to the second housing 012 and be electrically connected to a second electronic device disposed on the second housing 012. For example, the first extension Q6 can be electrically connected to a circuit board disposed on the first housing 011, and the second extension Q7 can be electrically connected to a battery disposed on the second housing 012.

[0118] Figure 14 Partial physical structure diagrams of the electronic device 100 of this application are provided, and Figure 14 This is an exploded view. In this... Figure 14 The diagram shows how the flexible circuit board 05 is mounted on the first housing 011. The mounting method of the flexible circuit board 05 on the second housing 012 can be referred to the mounting method of the flexible circuit board 05 on the first housing 011.

[0119] See Figure 14As shown, the first housing 011 has a first through hole 011a that passes through the first surface A1 and the second surface B2, and the first through hole 011a is opened near the rotating shaft structure 02. In this way, a part of the flexible circuit board 05 can pass through the first through hole 011a from the first surface A1 of the first housing 011 and go around to the second surface B1. It can also be understood that by opening the first through hole in the first housing 011, the bent flexible circuit board 05 can be accommodated.

[0120] In addition, for example Figure 14 The first mounting surface M1 is formed on the side wall of the first through hole 011a away from the rotating shaft structure 02. Thus, the reinforcing plate can be fixed on the first mounting surface M1 of the first through hole 011a. A portion of the flexible circuit board 05 passes through the first mounting surface M1 of the first through hole 011a from the first surface A1 and wraps around to the second surface B1.

[0121] Figure 15 What is given is Figure 14 A cross-sectional view along the BB direction after the flexible circuit board 05 and the first housing 011 are assembled. Figure 16 yes Figure 15 A magnified view of point C. (See image below.) Figure 16 The diagram shows a first mounting surface M1 formed on the first housing 011, a reinforcing plate 06 fixed on the first mounting surface M1, and a portion of the flexible circuit board 05 fixed to the reinforcing plate 06 by an adhesive layer 09.

[0122] For example Figure 16 As shown, the third mounting surface M3 for supporting the waterproof structure is also formed on the side wall surface of the first through hole 011a, which has the first mounting surface M1. With this design, when the first through hole 011a is opened, the inclined first mounting surface M1 and the horizontal third mounting surface M3 can be formed together. From a process perspective, this simplifies the manufacturing process, eliminating the need for additional structural components supporting the waterproof structure 11 near the first through hole 011a. From the perspective of the overall electronic device structure, this makes the entire electronic device structure more compact while achieving waterproofing, thus meeting the miniaturization design requirements of electronic devices.

[0123] Furthermore, combined with Figure 16 The third mounting surface M3 is provided with a first waterproof layer 111, which is part of the waterproof structure. A portion of the flexible circuit board 05 extends from the first mounting surface M1 to the first waterproof layer 111, until it extends to the position where the first housing 011 is connected to the electronic device.

[0124] Please continue reading. Figure 16Since both the flexible circuit board 05 and the first waterproof layer 111 are located within the first through hole 011a of the first housing 011, in order to press the flexible circuit board 05 and the first waterproof layer 111 tightly within the first through hole 011a, as follows: Figure 16 As shown, the electronic device 100 of this application also includes a pressure plate structure 10, which is fixed on the first housing 011 and extends partially to the first through hole 011a to press the first fixing part Q1 of the flexible circuit board 05 onto the first mounting surface M1 and to press the third fixing part Q3 of the flexible circuit board 05 onto the third mounting surface M3.

[0125] To prevent water from entering the electronic components of the first housing 011 through the gap formed between the pressure plate structure 10 and the third fixing part Q3, in some optional implementation structures, a second waterproof layer 112, which is part of the waterproof structure, can also be filled into the gap between the pressure plate structure 10 and the third fixing part Q3. In this way, the third fixing part Q3 of the flexible circuit board 05 is clamped by the two waterproof structures to further improve the waterproof performance of the electronic device.

[0126] for Figure 16 The connection between the pressure plate structure 10 and the first housing 011 can be achieved using fasteners, such as bolts. Alternatively, the pressure plate structure 10 can be fixed to the first housing 011 by welding.

[0127] In the feasible assembly process, after the flexible circuit board 05 is pressed to the first housing 011 by the pressure plate structure 10, the dispensing process can be used to fill the gap in the first through hole 011a with glue to further improve the waterproof performance.

[0128] The waterproof layer involved in this application can be made of silicone or double-sided adhesive with a polyester resin (PET) substrate.

[0129] Figure 17 What is given is a way to set Figure 15 and Figure 16 The structural diagram of the reinforcing plate 06 on the first mounting surface M1 is shown in the diagram. Figure 17 In the middle, the reinforcing plate 06 includes a first end ear 06a and a second end ear 06b arranged opposite to each other. Correspondingly, an inlay groove for embedding the first end ear 06a and an inlay groove for embedding the second end ear 06b can be formed on the first housing 011. In this way, when fixed... Figure 16 When the reinforcing plate 06 is installed, the first end ear 06a and the second end ear 06b can be embedded into the corresponding inlay groove to further enhance the connection strength between the reinforcing plate 06 and the first housing 011.

[0130] The following is combined Figure 18 and Figure 19 This section describes the positional relationship between the flexible circuit board 05 and the rotating shaft structure 02 in some feasible layout methods. Among them, Figure 18 The diagram shown is an exploded view of part of the structure of electronic device 100. Figure 19 What is given is Figure 18 A cross-sectional view along the CC direction after the flexible circuit board 05 and the rotating shaft structure 02 are assembled. Figure 18 As shown, the rotating shaft structure 02 has opposing surfaces A3 and B3. Surface A3 can be referred to as the fifth surface, and surface B3 can be referred to as the sixth surface. Surface A3 and the first surface A1 of the first housing 011 are on the same side, and surface B3 and the second surface B1 of the first housing 011 are on the same side. A second through hole 02a is provided on the rotating shaft structure 02, penetrating surfaces A3 and B3. Figure 19 At least a portion of the bent portion Q3 of the flexible circuit board 05 can pass through the second through hole 02a from surface A3 to surface B3. In other words, by opening a through hole in the pivot structure 02 to provide space for the bending of the bent portion Q3, such a flexible circuit board structure can be called an over-pivot cable electrical connection structure.

[0131] Of course, because Figure 18 and Figure 19 The flexible circuit board 05 includes a protrusion facing surface B3, thereby creating a through hole in the pivot structure 02. In other implementations, if the flexible circuit board 05 includes more protrusions, correspondingly, more through holes can be created in the pivot structure 05, thus providing space for bending of the multiple protrusions.

[0132] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0133] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
