Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of terminals, and particularly to a folding screen device. Background Art

[0002] With the explosive growth of electronic devices, the functions of electronic devices are becoming more and more numerous. The display screen of an electronic device is used to present image information to a user. In some usage scenarios, the user expects the display screen of the electronic device to have a larger display area. Currently, electronic devices have single-screen displays, and a larger display area means a larger size of the electronic device, thus making the electronic device lose its portability.

[0003] In order to balance the size and display area of an electronic device, the electronic device can adopt a folding structure. For example, two frames can rotate relative to each other around a rotating shaft in a rotating shaft assembly. A flexible display screen is covered on the two frames. When the two frames rotate around the rotating shaft to the same plane, the flexible display screen is in an unfolded state and has a larger display area. When the two frames rotate around the rotating shaft to be folded with each other, the flexible display screen is in a folded state, and the electronic device has a smaller volume. Electronic components are arranged in the two frames. The electronic components in different frames are electrically connected through a flexible electrical connection line that spans the rotating shaft.

[0004] In order to adapt to the morphological changes of the electronic device that can be folded and unfolded, the flexible electrical connection line needs to have a redundant length. When the two frames are in a folded state, the flexible electrical connection line can be in a taut state. When the two frames are in an unfolded state, the flexible electrical connection line is in a relaxed and free state, generating a length redundancy. However, every time the electronic device is folded and unfolded, the flexible electrical connection line presents different bending states, and it is easy to have a problem that the bending angle is too small, resulting in breakage of the electrical connection line due to bending. Summary of the Invention

[0005] The embodiments of the present application provide a folding screen device, which can reduce the possibility that the electrical connection line is arbitrarily bent and deformed due to length redundancy and the bending radius is too small, resulting in wear or breakage of the electrical connection line.

[0006] The present application provides a folding screen device, which at least includes a housing, an electrical connection line, and a shaping component.

[0007] The housing includes a rotating shaft assembly, a frame body, and a receiving portion. The frame body is rotatably connected to the rotating shaft assembly. The frame bodies are respectively disposed on opposite sides of the rotating shaft assembly. The frame bodies on both sides can rotate around the rotating shaft assembly to be folded or unfolded. The receiving portion is disposed on the rotating shaft assembly and the frame body. The receiving portion penetrates through the rotating shaft assembly. Both ends of the electrical connection line are respectively disposed in the frame bodies on both sides of the rotating shaft assembly. At least a portion of the electrical connection line is located in the receiving portion. The electrical connection line is disposed through the rotating shaft assembly. A shaping member is disposed in the receiving portion and is connected to the housing. At least a portion of the shaping member is located between the housing and the electrical connection line. The shaping member is used to guide and shape the portion of the electrical connection line located in the receiving portion.

[0008] In the folding screen device according to the embodiment of the present application, both ends of the electrical connection line are respectively disposed in two frame bodies. The electrical connection line is disposed through the rotating shaft assembly. At least a portion of the electrical connection line is located in the receiving portion of the housing. The folding screen device further includes a shaping member disposed in the receiving portion. When the two frame bodies are switched from the folded state to the unfolded state, the electrical connection line will have a length redundancy. The shaping member can guide and shape the portion of the electrical connection line located in the receiving portion, so that the electrical connection line can be deformed into an expected bending state. The shaping member can contact the electrical connection line to form a bending area in the corresponding area of the electrical connection line, increasing the number of bending areas, thereby absorbing the redundant length of the electrical connection line. Therefore, each time the two frame bodies are folded and unfolded, under the guiding and shaping action of the shaping member, the bending state of the electrical connection line itself can be kept consistent, and the shaping member can absorb the redundant length of the electrical connection line, which is beneficial to increasing the bending radius of the bending area formed on the electrical connection line, reducing the possibility that the electrical connection line is arbitrarily bent and deformed due to length redundancy and the bending radius is too small, resulting in wear or disconnection of the electrical connection line, and is beneficial to improving the reliability of the electrical connection line and the folding screen device.

[0009] In a possible implementation manner, the surface of the shaping member facing the electrical connection line is a curved surface.

[0010] When the shaping member contacts the electrical connection line, it is beneficial to disperse the acting force, reducing the possibility that the electrical connection line is cracked or disconnected due to stress concentration caused by the shaping member applying a large acting force locally to the electrical connection line.

[0011] In a possible implementation manner, the surface of the shaping member facing the electrical connection line is an arc surface.

[0012] In a possible implementation manner, the shaping member is disposed on the surface of the rotating shaft assembly facing the receiving portion. The shaping member protrudes toward the receiving portion. The portion of the electrical connection line located in the rotating shaft assembly is in a free state.

[0013] The shaping member protrudes towards the accommodating portion, so that the portion of the electrical connection line located at the rotating shaft assembly can form a bending area under the guiding action of the protruding shaping member to absorb the redundant length generated by the electrical connection line.

[0014] In a possible implementation manner, the rotating shaft assembly includes a shaft cover. The shaping member is arranged on the inner wall of the shaft cover facing the accommodating portion. The shaping member is used for guiding and shaping the portion of the electrical connection line located at the shaft cover.

[0015] The shaping member is used for guiding and shaping the portion of the electrical connection line located inside the shaft cover, so that the electrical connection line forms a bending area under the action of the shaping member. The electrical connection line can form a bending area with a larger radius within the limited space at the shaft cover to absorb the redundant length generated by the electrical connection line.

[0016] In a possible implementation manner, the surface of the shaping member facing the electrical connection line is in arc transition with the inner wall of the shaft cover, so that the transition between the shaping member and the shaft cover is gentle and smooth, reducing the possibility that the electrical connection line is easily damaged or scratched due to the existence of a sharp convex structure between the shaping member and the shaft cover.

[0017] In a possible implementation manner, the shaping member is arranged in the middle area of the shaft cover. The middle part of the electrical connection line can come into contact with the shaping member earlier, and the middle part of the electrical connection line forms a bending area with a larger radius under the action of the shaping member to absorb the redundant length of the electrical connection line. Thus, a bending area with a larger radius can also be formed between the middle part of the electrical connection line and the parts on both sides of the middle part.

[0018] In a possible implementation manner, the shaping members are arranged in the edge areas on both sides of the middle area of the shaft cover.

[0019] The shaping members arranged in the middle area and the edge areas can both guide and shape the portion of the electrical connection line located at the shaft cover, further enabling the electrical connection line to deform into the expected bending form. The shaping members arranged in the middle area and the edge areas can both make the corresponding areas on the electrical connection line form bending areas, which is beneficial to further increasing the number of bending areas to absorb more redundant length of the electrical connection line within the limited space, increasing the radius of each bending area, and thus being beneficial to further reducing the thickness of the folding screen device, and not easily causing the problem that the radius of the bending area is too small due to the reduction of the thickness of the folding screen device and the compression of the space of the accommodating portion, resulting in too large redundant length of the electrical connection line.

[0020] In a possible implementation, the protruding height of the shaping component provided in the middle region is greater than that of the shaping component provided in the edge region. On the one hand, it can ensure that the shaping component provided in the edge region occupies less space, so that there is enough storage space at the shaft cover to store the electrical connection line. On the other hand, if the protruding height of the shaping component provided in the edge region is too high, there is a risk that the electrical connection line is squeezed by the shaping component provided in the edge region, resulting in the electrical connection line not making contact with the shaping component provided in the middle region or having a small contact area, thus causing the shaping component provided in the middle region to fail to function effectively. The solution of this embodiment can help reduce the possibility of the above problems occurring.

[0021] In a possible implementation, the shaft cover and the shaping component are of an integrally formed structure.

[0022] The connection strength between the shaft cover and the shaping component is high, so that when the electrical connection line exerts a force on the shaping component, it is not easy for the shaping component to separate from the shaft cover. In addition, the shaft cover and the shaping component can be processed and manufactured simultaneously, which is beneficial to reducing the subsequent assembly process and improving production efficiency.

[0023] In a possible implementation, the shaping component is a flexible part. The shaping component is connected to the shaft cover.

[0024] The flexible shaping component has good softness. When the electrical connection line comes into contact with the shaping component, it is not easy for wear to occur between the shaping component and the electrical connection line, reducing the possibility of structural damage or disconnection failure of the electrical connection line due to long-term wear by the shaping component.

[0025] In a possible implementation, the shaping component is provided on the surface of the frame body facing the accommodating part. The shaping component is used to guide and shape the part of the electrical connection line located at the frame body.

[0026] The shaping component provided on the frame body can cause the corresponding area of the electrical connection line to bend and form a bending area with a larger radius to absorb the redundant length of the electrical connection line, and the shaping component can guide the bending deformation of the electrical connection line, which is beneficial to improving the consistency of the bending shape when the electrical connection line is repeatedly bent.

[0027] In a possible implementation, the shaping components are respectively provided in the areas on both sides of the electrical connection line on the frame body.

[0028] The shaping components on both sides can guide and shape the part of the electrical connection line located at the housing, further ensuring that the electrical connection line deforms into the expected bending shape. The shaping components on both sides can form bending areas in the corresponding areas on the electrical connection line, which is beneficial to further increase the number of bending areas, absorb more redundant lengths of the electrical connection line in a limited space, and increase the radius of each bending area. Therefore, it is beneficial to reduce the thickness of the folding screen device and prevent the problem of the radius of the bending area being too small due to the reduction of the thickness of the folding screen device compressing the space of the accommodating part and resulting in an excessive redundant length of the electrical connection line.

[0029] In a possible implementation manner, the middle part of the electrical connection line is connected to the rotating shaft assembly.

[0030] In a possible implementation manner, the housing and the shaping component are of an integrally formed structure.

[0031] The connection strength between the housing and the shaping component is high. Therefore, when the electrical connection line applies a force to the shaping component, it is not easy for the shaping component to separate from the housing. In addition, the housing and the shaping component can be processed and manufactured simultaneously, which is beneficial to reducing the later assembly process and improving production efficiency.

[0032] In a possible implementation manner, the shaping component is a flexible part. The shaping component is connected to the housing.

[0033] The flexible shaping component has good softness. Therefore, when the electrical connection line comes into contact with the shaping component, it is not easy for wear to occur between the shaping component and the electrical connection line, reducing the possibility of structural damage or wire breakage failure of the electrical connection line caused by long-term wear of the electrical connection line by the shaping component.

[0034] In a possible implementation manner, the housing includes a screen support plate and a flexible protection part. The flexible protection part is arranged on the surface of the screen support plate facing the electrical connection line. The flexible protection part is arranged facing the rotating shaft assembly. The electrical connection line passes through between the rotating shaft assembly and the flexible protection part.

[0035] When the electrical connection line undergoes bending deformation, the electrical connection line can come into contact with the flexible protection part, and the flexible protection part can play a buffering and protecting role for the electrical connection line, reducing the possibility of structural damage to the electrical connection line caused by the electrical connection line directly contacting the sharp corner structure existing on the screen support plate.

[0036] In a possible implementation manner, the electrical connection line includes a flexible circuit board.

[0037] In a possible implementation, the shaping component is a strip-shaped structure extending along the width direction of the flexible circuit board, so as to fully guide and shape the entire flexible circuit board in the width direction of the flexible circuit board.

[0038] In a possible implementation, the number of the flexible circuit boards is more than two. More than two of the flexible circuit boards are stacked. BRIEF DESCRIPTION OF THE DRAWINGS

[0067] The electronic device in the embodiments of the present application may be referred to as a user equipment (UE) or a terminal, etc. For example, the electronic device may be a portable android device (PAD), a personal digital assistant (PDA), a handheld device with wireless communication function, a computing device, a vehicle-mounted device, a wearable device, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, etc., which can be either a mobile terminal or a fixed terminal. In the embodiments of the present application, the form of the terminal device is not specifically limited.

[0068] In the embodiments of the present application, a handheld device with wireless communication function is taken as an example for illustration. The handheld device with wireless communication function may be, for example, a foldable screen device. The foldable screen device may be a foldable mobile phone including a foldable flexible display screen.

[0069] In the related art, the foldable screen device includes a frame body, a rotating shaft assembly and an electrical connection line. The frame bodies are respectively arranged on both sides of the rotating shaft assembly. The frame bodies can rotate relative to the rotating shaft assembly, so that the two frame bodies can change between the folded state and the unfolded state. Electronic devices are respectively arranged in the two frame bodies. The electronic devices in different frame bodies can be electrically connected through a flexible electrical connection line. The electrical connection line is arranged through the rotating shaft assembly. When the two frame bodies switch between the folded state and the unfolded state, the form of the electrical connection line will change. When the two frame bodies are in the unfolded state, the electrical connection line has length redundancy and is in a freely bent state. However, for each folding and unfolding of the frame bodies, the electrical connection line will present different bending states, making the electrical connection line prone to problems such as too small bending radius, resulting in wear and breakage, thus causing the electrical connection line to fail and the electronic device to malfunction.

[0070] The folding screen device provided by the embodiment of the present application can guide and shape the morphological changes of the electrical connection line, and can effectively absorb the redundant length of the electrical connection line, which is beneficial to keeping the bending state of the electrical connection line consistent every time the frame is folded and unfolded, and reducing the possibility of wear or disconnection of the electrical connection line due to too small bending radius. The implementable ways provided by the embodiment of the present application will be elaborated below.

[0071] Figure 1 Schematically shows the structure of the folding screen device 10 in the unfolded state of an embodiment. Figure 2 Schematically shows the structure of the folding screen device 10 in the semi-folded state. Figure 3 Schematically shows the structure of the folding screen device 10 in the folded state. Refer to Figures 1 to 3 As shown, the folding screen device 10 includes a housing 20 and a flexible display screen 30. The housing 20 includes a rotating shaft assembly 21 and a frame 22. The frame 22 is rotatably connected to the rotating shaft assembly 21. The frame 22 is provided on both sides of the rotating shaft assembly 21. The flexible display screen 30 is connected to the frame 22.

[0072] The frame 22 can rotate and fold relative to the rotating shaft assembly 21. In the present application, it is exemplified that the folding screen device 10 includes two frames 22. When the two frames 22 are stacked on top of each other, the folding screen device 10 is in the folded state. When the two frames 22 move away from the stacked state and unfold to the same plane, the folding screen device 10 is in the unfolded state. The process of the frame 22 from the folded state to the unfolded state is the unfolding process, and from the unfolded state to the folded state is the folding process.

[0073] Figure 4 Schematically shows the partial exploded structure of the folding screen device 10 of the present application. Refer to Figure 4 As shown, the flexible display screen 30 includes a display part for displaying image information. When the folding screen device 10 is in the unfolded state, the display part of the flexible display screen 30 unfolds to present image information to the user. The display part includes a first display area 31, a second display area 32 and a third display area 33. The first display area 31 and the second display area 32 are respectively provided corresponding to the two frames 22. The third display area 33 is provided corresponding to the rotating shaft assembly 21. The flexible display screen 30 itself has bendable performance and can be folded under the action of an external force.

[0074] When the two frames 22 are in the folded state, the display part is in the bent state. The first display area 31 and the second display area 32 of the display part are stacked on top of each other, and the third display area 33 can be bent into an arc state.

[0075] When the two frames 22 are in the unfolded state, the display part is in the unfolded state, and the first display area 31, the second display area 32, and the third display area 33 are in a flat state. When the display part of the flexible display screen 30 is in the unfolded state, the whole has good flatness.

[0076] The folding screen device 10 can change its overall size by folding or unfolding, and can also have a large display area in the unfolded state.

[0077] See Figure 4 As shown, electronic devices 80 can be respectively arranged in the two frames 22 of the folding screen device 10. For example, the electronic devices 80 can include, but are not limited to, a processor, a memory, or a camera module. The folding screen device 10 further includes an electrical connection line 40. The electrical connection line 40 is arranged through the rotating shaft assembly 21. The two end portions 41 of the electrical connection line 40 are arranged in the frames 22 on both sides of the rotating shaft assembly 21. Exemplarily, the two opposite end portions 41 of the electrical connection line 40 are respectively connected to the frames 22 on both sides of the rotating shaft assembly 21. It should be noted that the connection of the end portion 41 of the electrical connection line 40 to the frame 22 can mean that the end portion 41 of the electrical connection line 40 is directly connected and fixed to the frame 22, or the end portion 41 of the electrical connection line 40 is connected and fixed to other structural members in the frame 22 to be indirectly connected and fixed in the frame 22 through the structural members. The respective electronic devices 80 in the two frames 22 can be electrically connected through the electrical connection line 40 to transmit electrical signals. In some examples, a printed circuit board 70 (Printed Circuit Board, PCB) is arranged in the frame 22. The electronic device 80 is arranged on the printed circuit board 70. The electrical connection line 40 can be electrically connected to the printed circuit board 70. The end portion 41 of the electrical connection line 40 can be indirectly connected and fixed in the frame 22 through the printed circuit board 70.

[0078] In some implementable ways, the electrical connection line 40 can include a flexible printed circuit board (Flexible Printed Circuit, FPC). The flexible printed circuit board can include multiple traces for transmitting multiple different electrical signals. In some examples, the electrical connection line 40 can include more than two flexible printed circuit boards. The more than two flexible printed circuit boards are arranged in a stacked manner. The more than two flexible printed circuit boards can be connected at their respective end portions, and there can be no connection relationship in their respective other regions.

[0079] In some implementable ways, the electrical connection line 40 can include at least one single cable arranged independently. The cable can be used for electrically connecting two electronic devices 80 respectively arranged in the two frames 22.

[0080] Figure 5 Schematically shows a partial cross-sectional structure of a folding screen device in the related art. See Figure 5As shown, the electrical connection line 40 itself is a flexible structure. When the position of the frame 22 changes, the electrical connection line 40 can undergo corresponding deformation. When the two frames 22 are in a folded state, the electrical connection line 40 can be in a taut state. Figure 6 Schematically shows a partial cross-sectional structure of a folding screen device in the related art. Refer to Figure 6 As shown, when the frame 22 is in an unfolded state, the electrical connection line 40 will become slack and its length will be redundant, so that it will undergo free bending deformation by itself, making it easy for the electrical connection line 40 to have bending regions with a relatively small bending radius.

[0081] Figure 7 Schematically shows a partial cross-sectional structure of the folding screen device 10 of the present application. Refer to Figure 7 As shown, the housing 20 further includes a receiving portion 23. The receiving portion 23 is provided on the rotating shaft assembly 21 and the frame 22. The receiving portion 23 penetrates through the rotating shaft assembly 21 and extends into the frame 22, so that the receiving portion 23 can form a wiring channel. At least part of the electrical connection line 40 is located in the receiving portion 23. The electrical connection line 40 is arranged to pass through the rotating shaft assembly 21. The folding screen device 10 further includes a shaping member 50. The shaping member 50 is provided in the receiving portion 23 and is connected to the housing 20. At least part of the shaping member 50 is located between the housing 20 and the electrical connection line 40. The shaping member 50 is used to guide and shape the part of the electrical connection line 40 located in the receiving portion 23. The shaping member 50 can be provided on the surface of the housing 20 facing the receiving portion 23. When the two frames 22 are switched from the folded state to the unfolded state, the shaping member 50 can guide and shape the morphological changes during the bending process of the electrical connection line 40, so that the electrical connection line 40 can deform into the expected bending state. In addition, the shaping member 50 can abut against the electrical connection line 40 to form a bending region in the corresponding area on the electrical connection line 40, thereby increasing the number of bending regions on the electrical connection line 40, and then absorbing the redundant length of the electrical connection line 40.

[0082] In the folding screen device 10 according to the embodiment of the present application, the two end portions 41 of the electrical connection line 40 are respectively disposed in the two frame bodies 22. The electrical connection line 40 is disposed through the rotation shaft assembly 21. At least a part of the electrical connection line 40 is located in the accommodating portion 23 of the housing 20. The folding screen device 10 further includes a shaping member 50 disposed in the accommodating portion 23. When the two frame bodies 22 are switched from the folded state to the unfolded state, the electrical connection line 40 will have a length redundancy. The shaping member 50 can guide and shape the part of the electrical connection line 40 located in the accommodating portion 23, so that the electrical connection line 40 can be deformed into an expected bending state. The shaping member 50 can be in contact with the electrical connection line 40, so that a corresponding area of the electrical connection line 40 forms a bending area, increasing the number of bending areas, thereby absorbing the redundant length of the electrical connection line 40. Therefore, each time the two frame bodies 22 are folded and unfolded, under the guiding and shaping action of the shaping member 50, the bending state of the electrical connection line 40 can be kept consistent, and the shaping member 50 can absorb the redundant length of the electrical connection line 40, which is beneficial to increasing the bending radius of the bending area formed on the electrical connection line 40, reducing the possibility that the electrical connection line 40 is arbitrarily bent and deformed due to length redundancy and the bending radius is too small, resulting in wear or disconnection of the electrical connection line 40, and is beneficial to improving the reliability of the electrical connection line 40 and the folding screen device 10.

[0083] In some usage scenarios of the folding screen device 10, for example, when the folding screen device 10 is in a carrying state, the folding screen device 10 is usually in a folded state, so that the overall thickness dimension of the folding state of the folding screen device 10 has a greater impact on the convenience and experience of the usage process. The shaping member 50 provided in the folding screen device 10 of the present application can ensure that the electrical connection line 40 forms a bending area with a larger radius in a limited space, thereby being beneficial to reducing the thickness of the folding screen device 10 when the bending form of the electrical connection line 40 meets the requirements, so as to improve the convenience and experience of the folding screen device 10.

[0084] In some realizable ways, since the electrical connection line 40 will contact the surface of the shaping member 50 facing the electrical connection line 40, after the contact between the two, there is a compressive stress between the shaping member 50 and the electrical connection line 40. The surface of the shaping member 50 facing the electrical connection line 40 can be a curved surface. Therefore, when the shaping member 50 contacts the electrical connection line 40, the contact area between the shaping member 50 and the electrical connection line 40 has a smooth transition, which is beneficial to dispersing the compressive stress existing between the two, and reducing the possibility that the electrical connection line 40 is cracked or disconnected due to stress concentration caused by the shaping member 50 applying a large pressure on a local area of the electrical connection line 40. When the electrical connection line 40 contacts the shaping member 50, the surface of the shaping member 50 facing the electrical connection line 40 can better guide the electrical connection line 40 to bend, forming a bending area with a larger bending radius.

[0085] In some examples, the surface of the shaping member 50 facing the electrical connection line 40 is an arc surface. Exemplarily, the surface of the shaping member 50 facing the electrical connection line 40 includes a plurality of arc surfaces. The plurality of arc surfaces are smoothly transitioned between each other.

[0086] In some implementable ways, a shaping member 50 is disposed on the surface of the rotating shaft assembly 21 facing the accommodating portion 23. The shaping member 50 protrudes toward the accommodating portion 23, so that the portion of the electrical connection line 40 located at the rotating shaft assembly 21 can form a bending area under the guiding action of the protruding shaping member 50 to absorb the redundant length generated by the electrical connection line 40. The portion of the electrical connection line 40 located inside the rotating shaft assembly 21 is in a free state, that is, the electrical connection line 40 is in a non-connected state with the rotating shaft assembly 21, so that the electrical connection line 40 is not pulled and constrained by the rotating shaft assembly 21. Therefore, the portion of the electrical connection line 40 located inside the rotating shaft assembly 21 is easily deformed as the frame body 22 is folded or unfolded.

[0087] In some examples, referring to Figure 7 As shown, the rotating shaft assembly 21 includes a shaft cover 211. The shaft cover 211 can be located between the two frame bodies 22. The shaft cover 211 can block other structural members inside the rotating shaft assembly 21, making the appearance of the electronic device neat and beautiful. When the two frame bodies 22 rotate relative to the rotating shaft assembly 21, the position of the shaft cover 211 can remain relatively fixed. In some examples, when the two frame bodies 22 are in the unfolded state, the two frame bodies 22 can block the shaft cover 211 to make the shaft cover 211 in an invisible state. When the two frame bodies 22 are in the folded state, at least a part of the shaft cover 211 can be exposed outside the two frame bodies 22 and be in a visible state.

[0088] The electrical connection line 40 is arranged across the shaft cover 211. The two end portions 41 of the electrical connection line 40 are respectively located on both sides of the shaft cover 211. The shaping member 50 can be disposed on the inner wall of the shaft cover 211 facing the accommodating portion 23. The shaping member 50 is disposed between the shaft cover 211 and the electrical connection line 40. The shaping member 50 is used to guide and shape the portion of the electrical connection line 40 located inside the shaft cover 211, so that the electrical connection line 40 forms a bending area under the action of the shaping member 50. The electrical connection line 40 can form a bending area with a larger radius in the limited space at the shaft cover 211 to absorb the redundant length generated by the electrical connection line 40.

[0089] In some examples, Figure 8 Schematically shows a partial cross-sectional structure of the foldable screen device 10 of the present application. Referring to Figure 8As shown, the shaft cover 211 may include a recessed portion 211a. The recessed portion 211a of the shaft cover 211 is formed as a part of the accommodating portion 23. Since the shaft cover 211 includes the recessed portion 211a, the space of the accommodating portion 23 at the shaft cover 211 is larger, so that when the frame 22 is in the unfolded state, a part of the electrical connection line 40 can be accommodated in the recessed portion 211a of the shaft cover 211 in a bent form. The shaping member 50 can guide and shape the electrical connection line 40 so that the electrical connection line 40 can be accommodated in the recessed portion 211a of the shaft cover 211 in an expected bent form.

[0090] In some examples, the surface of the shaping member 50 facing the electrical connection line 40 has an arc transition with the inner wall of the shaft cover 211, so that the transition between the shaping member 50 and the shaft cover 211 is gentle and smooth, reducing the possibility that the electrical connection line 40 is prone to structural damage or scratching due to the presence of a sharp convex structure between the shaping member 50 and the shaft cover 211.

[0091] In some examples, the middle part of the electrical connection line 40 is located inside the shaft cover 211. When the frame 22 is switched from the folded state to the unfolded state, the electrical connection line 40 has a length redundancy, and under the action of its own internal stress, the middle part of the electrical connection line 40 will move towards the middle area 211b of the shaft cover 211. Therefore, the shaping member 50 is provided in the middle area 211b of the shaft cover 211, so that the middle part of the electrical connection line 40 can come into contact with the shaping member 50 earlier, and the middle part of the electrical connection line 40 forms a bent area with a larger radius under the action of the shaping member 50 to absorb the redundant length of the electrical connection line 40, so that a bent area with a larger radius can also be formed between the middle part of the electrical connection line 40 and the parts on both sides of the middle part.

[0092] In some examples, Figure 9 Schematically shows a partial cross-sectional structure of the folding screen device 10 of the present application. Refer to Figure 9As shown, shaping components 50 are provided on the edge regions 211c on both sides of the middle region 211b of the shaft cover 211. The shaping components 50 provided on the edge regions 211c can be arranged close to the opening of the recess 211a. The shaping components 50 arranged relative to the middle region 211b can be closer to the end 41 of the electrical connection line 40. The shaping components 50 provided on the middle region 211b and the edge regions 211c can both guide and shape the portion of the electrical connection line 40 located at the shaft cover 211, further enabling the electrical connection line 40 to deform into an expected bending shape. The shaping components 50 provided on the middle region 211b and the edge regions 211c can both form bending regions on the corresponding regions of the electrical connection line 40, which is beneficial for further increasing the number of bending regions to absorb more redundant lengths of the electrical connection line 40 in a limited space and increasing the radius of each bending region, thereby being beneficial for further reducing the thickness of the folding screen device 10 and preventing the problem that the redundant length of the electrical connection line 40 is too large and the radius of the bending region is too small due to the compression of the space of the accommodating portion 23 caused by the reduction of the thickness of the folding screen device 10.

[0093] In some examples, there is an arc transition between the shaping component 50 and the shaft cover 211, so that an arc-shaped recess is formed between the shaping component 50 provided on the middle region 211b and the shaping component 50 provided on the edge region 211c. A part of the electrical connection line 40 can be located within the arc-shaped recess.

[0094] In some examples, refer to Figure 9 As shown, the electrical connection line 40 includes more than two flexible circuit boards. The more than two flexible circuit boards are stacked. During the unfolding process of the frame 22, if the bending shapes of the flexible circuit boards are inconsistent, delamination will occur between the flexible circuit boards. When the delaminated flexible circuit boards are attached to each other again, it is easy to produce slapping against each other, resulting in abnormal noise in the folding screen device 10 and affecting the user experience. The shaping components 50 provided on the middle region 211b and the edge regions 211c can effectively limit the movement space of each flexible circuit board, and the shaping components 50 can guide and shape the bending shapes of each flexible circuit board during the unfolding process of the frame 22, so that the redundant lengths of each flexible circuit board are absorbed in the same shape, so that the changing trends of the bending shapes of each flexible circuit board are consistent, reducing the possibility of delamination between the flexible circuit boards caused by inconsistent bending shapes of each flexible circuit board, and thus being beneficial for eliminating the problem of abnormal noise generated by the slapping of the flexible circuit boards against each other. In some examples, the shaping component 50 can be a strip-shaped structure extending along the width direction of the flexible circuit board, so that the entire flexible circuit board can be fully guided and shaped in the width direction of the flexible circuit board.

[0095] In some examples, a shaping component 50 can be arranged in the middle region 211b, and a shaping component 50 can be arranged in each of the edge regions 211c on both sides, that is, three shaping components 50 are arranged on the shaft cover 211. However, it can be understood that other numbers of shaping components 50 can be arranged in the middle region 211b and the edge regions 211c, and the present application does not make specific limitations in this regard.

[0096] In some examples, the protruding height of the shaping component 50 arranged in the middle region 211b is greater than the protruding height of the shaping component 50 arranged in the edge region 211c. On the one hand, it can ensure that the shaping component 50 arranged in the edge region 211c occupies less space, so that there is enough storage space at the shaft cover 211 to store the electrical connection line 40; on the other hand, if the protruding height of the shaping component 50 arranged in the edge region 211c is too high, there is a risk that the electrical connection line 40 is squeezed by the shaping component 50 arranged in the edge region 211c, resulting in the electrical connection line 40 not contacting the shaping component 50 arranged in the middle region 211b or having a small contact area, so that the shaping component 50 arranged in the middle region 211b fails to function effectively, and the solution of this embodiment can help reduce the possibility of the above problems occurring.

[0097] In some examples, the shapes and sizes of the shaping components 50 arranged in the two edge regions 211c on both sides can be the same, so as to improve the consistency of the bending form of the electrical connection line 40 in the regions corresponding to the two shaping components 50 on both sides and improve the consistency of the radius of the bending regions formed by the electrical connection line 40 in the regions corresponding to the two shaping components 50 on both sides.

[0098] In some examples, the shaft cover 211 and the shaping component 50 are of an integrally formed structure. The connection strength between the shaft cover 211 and the shaping component 50 is high, so that when the electrical connection line 40 exerts a force on the shaping component 50, it is not easy for the shaping component 50 to separate from the shaft cover 211. In addition, the shaft cover 211 and the shaping component 50 can be processed and manufactured simultaneously, which is beneficial to reducing the later assembly process and improving production efficiency.

[0099] In some examples, referring to Figure 9 As shown, the height by which the shaping component 50 arranged in the middle region 211b protrudes from the bottom wall of the shaft cover 211 can be H1. The height from the bottom wall to the top surface of the shaft cover 211 can be H2. Among them, 0.5≤H1<0.5H2. Exemplarily, the value range of H2 can be from 1 millimeter to 4 millimeters.

[0100] In some examples, Figure 10 Schematically shows a partial cross-sectional structure of the folding screen device 10 of the present application. Referring to Figure 10As shown, the shaping component 50 can be a flexible component. The shaping component 50 is connected to the shaft cover 211. Exemplarily, the shaping component 50 can be bonded to the inner wall of the shaft cover 211. For example, the shaping component 50 can be bonded to the inner wall of the shaft cover 211 by an adhesive or double-sided tape. The flexible shaping component 50 has good softness, so when the electrical connection line 40 comes into contact with the shaping component 50, it is not easy for wear to occur between the shaping component 50 and the electrical connection line 40, reducing the possibility of structural damage or disconnection failure of the electrical connection line 40 caused by long-term wear of the electrical connection line 40 by the shaping component 50. Exemplarily, the material of the shaping component 50 can be foam.

[0101] In some realizable ways, refer to Figure 10 As shown, the frame 22 includes a screen support plate 221 and a flexible protective component 222. The flexible display screen 30 is arranged on the screen support plate 221. The screen support plate 221 is used to provide a supporting force for the flexible display screen 30 to prevent the flexible display screen 30 from collapsing. When the frame 22 is in the unfolded state, the two screen support plates 221 can keep the flexible display screen 30 in a flat state. The flexible protective component 222 is arranged on the surface of the screen support plate 221 facing the electrical connection line 40. The flexible display screen 30 and the flexible protective component 222 are respectively arranged on two opposite sides of the screen support plate 221. The flexible protective component 222 faces the rotating shaft assembly 21. The electrical connection line 40 passes through between the rotating shaft assembly 21 and the flexible protective component 222. When the electrical connection line 40 undergoes a bending deformation, the electrical connection line 40 can come into contact with the flexible protective component 222, and the flexible protective component 222 can play a buffering and protective role for the electrical connection line 40, reducing the possibility of structural damage to the electrical connection line 40 caused by the electrical connection line 40 directly contacting the sharp corner structure existing on the screen support plate 221. In some examples, the material of the flexible protective component 222 can be foam.

[0102] In some realizable ways, Figure 11 Schematically shows a partial cross-sectional structure of the folding screen of the present application. Refer to Figure 11As shown, a shaping member 50 is provided on the surface of the housing 22 facing the accommodating portion 23. The space of the accommodating portion 23 located within the housing 22 can accommodate the electrical connection line 40. The shaping member 50 is used to guide and shape the portion of the electrical connection line 40 located at the housing 22. The shaping member 50 provided on the housing 22 is closer to the end portion 41 of the electrical connection line 40. When the housing 22 is switched from the folded state to the unfolded state, the length of the portion of the electrical connection line 40 located within the housing 22 will have redundancy, and under the action of its own internal stress, the portion of the electrical connection line 40 located within the housing 22 will undergo bending deformation. Therefore, the shaping member 50 provided on the housing 22 can cause the corresponding area of the electrical connection line 40 to be bent to form a bending area with a relatively large radius, so as to absorb the redundant length of the electrical connection line 40, and the shaping member 50 can guide the bending deformation of the electrical connection line 40, which is beneficial to improving the consistency of the bending shape when the electrical connection line 40 is repeatedly bent.

[0103] In some examples, referring to Figure 11 As shown, shaping members 50 are respectively provided in the areas on both sides of the electrical connection line 40 on the housing 22. The electrical connection line 40 passes through between the shaping members 50 on both sides. The shaping members 50 on both sides can both guide and shape the portion of the electrical connection line 40 located at the housing 22, further ensuring that the electrical connection line 40 deforms into the expected bending shape. The shaping members 50 on both sides can both cause the corresponding areas on the electrical connection line 40 to form bending areas, which is beneficial to further increasing the number of bending areas, so as to absorb more redundant length of the electrical connection line 40 in a limited space, increase the radius of each bending area, thereby being beneficial to reducing the thickness of the folding screen device 10, and it is not easy to have the problem that the radius of the bending area is too small due to the reduction of the thickness of the folding screen device 10 compressing the space of the accommodating portion 23 and resulting in too much redundant length of the electrical connection line 40.

[0104] In some examples, the middle portion of the electrical connection line 40 is connected to the rotating shaft assembly 21. Exemplarily, the middle portion of the electrical connection line 40 is bonded to the rotating shaft assembly 21. For example, the middle portion of the electrical connection line 40 can be bonded to the rotating shaft assembly 21 through an adhesive or double-sided tape. The middle portion of the electrical connection line 40 is restricted by the rotating shaft assembly 21, so that the middle portion of the electrical connection line 40 cannot move or bend freely relative to the rotating shaft assembly 21. The shaping member 50 provided on the housing 22 can guide and shape the portion of the electrical connection line 40 extending out of the rotating shaft assembly 21.

[0105] In some examples, referring to Figure 11As shown, the housing 20 further includes a support member 60. The support member 60 is provided corresponding to the shaft cover 211 of the rotating shaft assembly 21. The middle part of the electrical connection line 40 can pass through between the support member 60 and the shaft cover 211. When the frame body 22 and the flexible display screen 30 are in a folded state, the support member 60 is used to support the bent third display area 33 on the flexible display screen 30, so that the bent third display area 33 on the flexible display screen 30 can present a water droplet shape, reducing the possibility that the third display area 33 of the flexible display screen 30 has too small a bending radius, resulting in creases or cracks in the third display area 33.

[0106] In some examples, the frame body 22 and the shaping member 50 are an integrally formed structure. The connection strength between the frame body 22 and the shaping member 50 is high, so that when the electrical connection line 40 applies a force to the shaping member 50, it is not easy for the shaping member 50 to separate from the frame body 22. In addition, the frame body 22 and the shaping member 50 can be processed and manufactured simultaneously, which is beneficial to reducing the later assembly process and improving production efficiency.

[0107] In some examples, refer to Figure 12 As shown, the distance between the opposite two surfaces of the frame body 22 facing the accommodating portion 23 can be H0. The protruding height of the shaping member 50 provided on one surface can be H3, and the protruding height of the shaping member 50 provided on the other surface can be H4. The electrical connection line 40 can be a flexible circuit board. The thickness of the flexible circuit board can be h. The value range of the protruding height H3 of the shaping member 50 provided on one surface can be: 0.5H0>H3>2h. The value range of the protruding height H4 of the shaping member 50 provided on the other surface can be: 0.5H0>H4>2h.

[0108] In some examples, Figure 13 Schematically shows a partial cross-sectional structure of the folding screen device 10 of the present application. Refer to Figure 13 As shown, the shaping member 50 can be a flexible member. The shaping member 50 is connected to the frame body 22. Exemplarily, the shaping member 50 can be adhered to the frame body 22. For example, the shaping member 50 can be adhered to the frame body 22 through an adhesive or double-sided tape. The flexible shaping member 50 has good softness, so that when the electrical connection line 40 comes into contact with the shaping member 50, it is not easy for wear to occur between the shaping member 50 and the electrical connection line 40, reducing the possibility that the electrical connection line 40 is structurally damaged or fails due to long-term wear by the shaping member 50. Exemplarily, the material of the shaping member 50 can be foam.
