Description

Technical Field

[0001] This application belongs to the technical field of electronic devices, and particularly relates to electronic devices. Background Art

[0002] In the mobile terminal industry, the competition is increasingly tending towards large screens and thinness. However, a large screen makes the overall size of the whole machine too large and inconvenient to carry. Foldable electronic devices can change the size of the electronic device due to their folding function, thus solving the above problems and are now widely loved by users. However, during the folding and unfolding process of the electronic device, creep caused by the viscous flow deformation of the adhesive layer in the flexible screen leads to irreversible deformation of the flexible screen after long-term use, that is, crease light and shadow are generated in the bending area, reducing the performance of the electronic device. Summary of the Invention

[0003] In view of this, this application provides an electronic device, including:

[0004] A folding device that can rotate around the axis direction to make the electronic device in a flattened state or a folded state;

[0005] Two housings, respectively fixed on opposite sides of the folding device;

[0006] A flexible screen, including a display part arranged on the same side of the folding device and the two housings; and

[0007] An adjusting device, arranged in the housing, the adjusting device includes a movable driving part and a driven mechanism, one end of the driven mechanism is connected to the driving part, and the other end is fixed to the flexible screen;

[0008] During the unfolding process of the electronic device, the driving part moves in the first direction, and then can control the driven mechanism to drive the display part on one housing to move away from the other housing, the first direction is perpendicular to the axis direction; during the folding process of the electronic device, the driving part moves in the second direction opposite to the first direction, and then can control the driven mechanism to drive the display part on one housing to move closer to the other housing.

[0009] The electronic device provided by this application controls the movement of the flexible screen by adding an adjusting device. The driving member in the adjusting device can move, and one end of the driven mechanism is connected to the driving member, and the other end is fixed to the flexible screen, so as to control the movement of the flexible screen by using the driving member and the driven mechanism. During the unfolding process of the electronic device, the driving member moves in the first direction, and then it can control the driven mechanism to drive the display part on one housing to move away from the other housing. In this way, when the electronic device is in the unfolded state, the flexible screen is in a taut state. When the flexible screen has creases, that is, when the display part on the folding device has folds, the display part on the folding device will also be subjected to tensile forces in opposite directions, thereby tightening the display part in this area, reducing the depth and light and shadow of the creases, making the flexible screen taut and improving the flatness of the bending area, and improving the flatness of the flexible screen in the flattened state.

[0010] During the folding process of the electronic device, the driving member moves in the second direction, and then it can control the driven mechanism to drive the display part on one housing to move closer to the other housing. In this way, the driven mechanism no longer applies a tensile force to the display part, that is, it relaxes the pulling on the flexible screen, ensuring the relative relaxation of the flexible screen in the bending area during the folding process, without adding additional extrusion or pulling to the flexible screen, enabling the flexible screen to be bent normally and improving the protection of the flexible screen. When the electronic device is in the folded state, the flexible screen can be in a relaxed state, enabling the flexible screen to achieve the best water droplet shape.

[0011] In summary, this application utilizes the characteristics that the electronic device can move during the bending process and has strong stiffness along the tangential direction to design an adjustable electronic device. Through the action of the user opening and closing the whole machine, the adjusting device pulls the flexible screen during the unfolding process, and the flexible screen in the flattened state is tightened, improving the flatness of the flexible screen in the bending area in the unfolded state and reducing the crease light and shadow in the bending area. During the entire folding process, the flexible screen is relaxed, protecting the flexibility of the flexible screen in the bending area in the folded state. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0028] The following are preferred implementations of the present application. It should be noted that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application, and these improvements and modifications are also considered to be within the scope of protection of the present application.

[0029] With the market demand for the "display area" of terminal products such as mobile phones and tablets, the competition in the mobile terminal industry is increasingly tending towards large screens and ultra-thinness. However, large screens make the size of the whole machine too large and inconvenient to carry. The smart phone industry is ushering in an experience revolution brought by form innovation. The display screen form of mobile phone products has developed from the initial hard screen to flexible screen, from small screen to large screen, from static mechanism to motion mechanism. Recently, major mobile phone manufacturers are developing folding screens, striving to expand the form and display boundaries of mobile phone products, so that they have the functions of mobile phones, tablets and even computers. As an electronic device with a new display screen form, flexible screens are an important application technology of organic light-emitting semiconductors (OLED). Compared with traditional screens, flexible screens have significant advantages, such as lighter and thinner volume, lower power consumption, and benefit from its bendability and flexibility. Therefore, it can be unfolded or closed with the folding device, and has a larger display area in the unfolded state and a smaller overall size in the folded state, which can solve the above problems. It is now loved by the majority of users.

[0030] At present, foldable electronic devices are mainly divided into two solutions: flexible screen folding inwards and flexible screen folding outwards. The advantage of the inward folding is that the shell can effectively protect the flexible screen and reduce the impact of external impact and wear, but the bending R angle of the inward folding flexible screen is smaller, and the local space optimization requirements of the folding device are high. In the market, there have been undesirable phenomena such as the flexible screen being pierced by the parts of the folding device. The advantage of the outward folding is that the bending R angle of the flexible screen does not need to be too small, and the flexible screen does not need to be unfolded when half of the screen is used. The disadvantage is that the flexible screen is exposed, the technology of flexible wear-resistant materials is immature, and the flexible screen has weak scratch resistance, which is easy to produce scratches or bumps.

[0031] At present, the inward folding flexible screens on the market are mainly divided into two types: U-shaped and teardrop-shaped. The U-shaped one has a smaller bending radius and a simple hinge structure, but its disadvantage is that the crease is deeper after unfolding. The advantage of the teardrop-shaped folding mechanism is that the bending radius is larger when merging, but the creep stress of the glue layer is smaller. It can maintain a relatively good crease level when unfolding, and the crease depth is smaller than the U-shaped bending form. However, whether it is U-shaped, teardrop-shaped or teardrop-shaped, due to the creep caused by the viscous flow deformation of the glue layer in the inner layer of the flexible screen during the folding and unfolding of the electronic device, the flexible screen will produce irreversible deformation after long-term opening and closing or use, that is, crease light and shadow will be generated in the bending area, affecting the performance and appearance of the electronic device, which has a negative impact on the user experience.

[0032] To solve the above problems, the present application provides an electronic device. Please refer to Figures 1-5 The electronic device 1 provided in this embodiment includes a folding device 10, two housings 20, a flexible screen 30, and an adjusting device 40. The folding device 10 can rotate around the axial direction to make the electronic device 1 in a flattened state or a folded state. The two housings 20 are respectively fixed on opposite sides of the folding device 10. The flexible screen 30 includes a display portion 31 disposed on the same side of the folding device 10 and the two housings 20. The adjusting device 40 is disposed in the housing 20 and is fixed to the flexible screen 30 on the housing 20. The adjusting device 40 can drive the flexible screen 30 to move.

[0033] The adjusting device 40 includes a movable driving member 41 and a driven mechanism 42. One end of the driven mechanism 42 is connected to the driving member 41, and the other end is fixed to the flexible screen 30. During the unfolding process of the electronic device 1, the driving member 41 moves in a first direction perpendicular to the axial direction, and thus can control the driven mechanism 42 to drive the display portion 31 on one housing 20 to move in a direction away from the other housing 20, and the first direction is perpendicular to the axial direction. During the folding process of the electronic device 1, the driving member 41 moves in a second direction opposite to the first direction, and thus can control the driven mechanism 42 to drive the display portion 31 on one housing 20 to move in a direction close to the other housing 20.

[0034] When the electronic device 1 includes two adjusting devices 40 respectively disposed in the two housings 20, during the unfolding process of the electronic device 1, the two adjusting devices 40 can drive the display portions 31 on the two housings 20 to move away from each other, so that the flexible screen 30 is in a taut state when the electronic device 1 is in the unfolded state. During the folding process of the electronic device 1, the two adjusting devices 40 can drive the display portions 31 on the two housings 20 to move towards each other, so that the flexible screen 30 is in a relaxed state when the electronic device 1 is in the folded state.

[0035] The electronic device 1 includes, but is not limited to, mobile terminals such as mobile phones, tablet computers, laptop computers, handheld computers, personal computers (PCs), personal digital assistants (PDAs), portable media players (PMPs), navigation devices, wearable devices, smart bracelets, pedometers, etc., and fixed terminals such as digital TVs, desktop computers, etc. This embodiment only takes the electronic device 1 as a folding mobile phone as an example for illustrative purposes. Optionally, this embodiment and the following only take an in-foldable folding mobile phone for illustrative purposes. Of course, in other embodiments, it can also be an out-foldable folding mobile phone.

[0036] The flexible screen 30 is the display module of the electronic device 1, which is itself a very thin flexible light-emitting layer, has a certain flexibility and can be bent, so the flexible screen 30 is a necessary condition for the foldable electronic device 1 to be folded and unfolded. The flexible screen 30 includes but is not limited to various flexible components with corresponding functions such as flexible display screens, flexible touch screens, and flexible touch display screens, or is a flexible component fixedly bonded with a flexible support plate, such as a flexible display screen bonded with a flexible steel plate, a flexible touch screen, etc. In product application, the flexible screen 30 must rely on a structure with a certain rigidity (such as a housing 20 and a folding device 10) to be convenient for users to use. The flexible screen 30 has a bending area and non-bending areas on both sides of the bending area. The bending area is the area where the flexible screen 30 will bend later, while the non-bending area will not bend. In other words, when the flexible screen 30 is bent, not all areas are bent, and only the flexible screen 30 in the bending area will bend.

[0037] Optionally, the flexible screen 30 is divided into structural layers, mainly including a flexible screen protection layer, a flexible screen functional layer, and a flexible screen buffer layer. The flexible screen protection layer is arranged on the outermost side to protect the surface of the flexible screen 30 from being scratched or bumped, and is made of a flexible material with a certain hardness, such as ultra-thin glass, PET, transparent PI, etc. The flexible screen functional layer encapsulates the circuit and the light-emitting material, and is the core layer of the flexible screen 30 display. The flexible screen buffer layer is arranged on the shell 20, and is made of a low-modulus soft material with a certain thickness. It absorbs the unevenness of the surface of the shell 20 to a certain extent, improves the impact resistance of the flexible screen functional layer, and has a higher roughness.

[0038] The folding device 10 can also be called a rotating shaft or a hinge. The movement of the folding device 10 can be controlled to control the folding and unfolding of the electronic device 1. The base in the folding device 10 is used as a basic component to install the remaining various components. The decorative member 11 in the folding device 10 is used to protect the base. The support member in the folding device 10 is used to support the flexible screen 30 in the bending area. This embodiment and the following only show the decorative member 11 in the folding device 10, and other structures are not shown. The folding device 10 can rotate around its axis direction. During the movement, the support member will fold and unfold, thereby driving the flexible screen 30 in the bending area to fold and unfold accordingly, so that the electronic device 1 is in a flattened state or a folded state. The axis direction is set along the length direction of the folding device 10. Therefore, for the electronic device 1 with bending characteristics, the deformation process of its flexible screen 30 is the movement process of the foldable device 10. As for the specific structure of the folding device 10, this embodiment will not be repeated here. It is sufficient to control the flexible screen 30 to bend, so as to avoid excessive local force on the flexible screen 30 during the movement, resulting in damage, delamination and other undesirable phenomena.

[0039] The two housings 20 are mainly used to install and carry components. For example, a flexible screen 30 can be carried on the housing 20, and functional modules such as a battery, a PCB assembly, a speaker, a receiver, a button, and an adjustment device 40 can also be arranged inside the housing 20. The two housings 20 are respectively arranged on the left and right sides of the folding device 10, and each housing 20 is fixed to a component of the folding device 10. In this way, when the folding device 10 folds and unfolds, it can drive the left and right housings 20 to fold and unfold together. Since the housing 20 only rotates relatively and does not deform itself, the flexible screen 30 in the non-bending area arranged on the housing 20 will not deform either. In other words, only the flexible screen 30 arranged on the folding device 10 will bend, and the flexible screen 30 on the housing 20 will not bend. The parameters such as the shape, material, and structure of the housing 20 are not limited in this embodiment, as long as it can achieve the functions of installation and protection. For example, the material of the housing 20 can be all metal, or all plastic, or part metal and part plastic.

[0040] The above content can also be understood as that for a book-style flexible screen 30 terminal product that realizes unfolding and folding by folding in half, in terms of structure, the bending of the flexible screen 30 needs to rely on the rigid housing 20 and the bendable folding device 10. The two housings 20 are connected by the folding device 10. The folding device 10 has a stable structure at a specific angle, and can rotate and bend when needed, and has a relatively smooth movement track on the side of the flexible screen 30. The flexible screen 30 follows the deformation of the housing 20 and the folding device 10 to realize the change of the bending and flattening states.

[0041] It should be noted that the flexible screen 30 can also be divided into a display part 31 and a non-display part 32 according to whether it has a display function. The display part 31 is the part of the flexible screen 30 that emits light and is used to display a picture for the user to view and operate. The non-display part 32 is the part of the flexible screen 30 that does not emit light, or even if it emits light, it is not used for the user to view and operate. The display part 31 can be bonded to the housings 20 on the left and right sides through structures such as a bonding layer 50, and abuts against the folding device 10, that is, the display part 31 is located above the folding device 10 and the two housings 20. The non-display part 32 is connected to the periphery of the display part 31. The non-display part 32 can also be arranged above the folding device 10 and the two housings 20, or the non-display part 32 can also be arranged inside the housing 20. The position of the non-display part 32 is not limited in this embodiment.

[0042] In addition, the electronic device 1 has an unfolded state and a folded state. The unfolded state is the state when the flexible screen 30 is flattened in one direction, and at this time, the electronic device 1 has the largest display area. The folded state is the state when both ends of the flexible screen 30 are folded relative to each other to form a U-shaped or water droplet shape, and at this time, the electronic device 1 has the smallest overall size. The folding process of the electronic device 1 is the process of the electronic device 1 changing from the unfolded state to the folded state, and the unfolding process of the electronic device 1 is the process of the electronic device 1 changing from the folded state to the unfolded state. From the above content, it can be seen that after the electronic device 1 is used for a period of time, that is, after the flexible screen 30 is bent a certain number of times, creases will be generated at the bending area of the flexible screen 30, which affects the use performance and appearance effect of the electronic device 1.

[0043] Therefore, in this embodiment, an adjusting device 40 can be added. The adjusting device 40 is arranged in the housing 20, and the adjusting device 40 is mainly used to control the movement of the flexible screen 30. Optionally, the number of the adjusting devices 40 can be one or two. When there is only one adjusting device 40, it can be arranged in any one of the housings 20. At this time, the flexible screen 30 on the other side can be directly fixed to the housing 20, or other structures can be provided to control the flexible screen 30 on the other side. When there are two adjusting devices 40, each adjusting device 40 is respectively arranged in one housing 20, that is, one adjusting device 40 is arranged in one housing 20, and the other adjusting device 40 is arranged in the other housing 20. Each adjusting device 40 is fixed to the flexible screen 30 arranged in the corresponding housing 20. Since the adjusting device 40 itself can move, the adjusting device 40 can drive the flexible screen 30 fixed thereon to move, so as to achieve the purpose of controlling the movement of the flexible screen 30. In this embodiment, only two adjusting devices 40 are used for illustrative purposes.

[0044] Optionally, in one embodiment, the adjusting device 40 can be an active device. For example, a motor can be used to make the adjusting device 40 move actively. In other embodiments, the adjusting device 40 can also be a driven device, that is, the adjusting device 40 itself does not move actively, but during the movement of the electronic device 1, the adjusting device 40 cooperates with other components to drive the adjusting device 40 to move, so that the adjusting device 40 moves adaptively, and finally controls the flexible screen 30 to move. In this embodiment, only the adjusting device 40 being a driven device is used for illustrative purposes. At this time, the electronic device 1 can also be called an electronic device 1 with an adaptive adjustment of the flexible screen 30.

[0045] During the unfolding process of the electronic device 1, the two adjusting devices 40 can drive the display parts 31 on the two housings 20 to move away from each other. The display part 31 can be divided into three parts: the display part 31 on the left housing, the display part 31 on the folding device 10, and the display part 31 on the right housing. Therefore, in this embodiment, the adjusting device 40 located in the left housing can drive the display part 31 on the left housing to move leftward, and the adjusting device 40 located in the right housing can drive the display part 31 on the right housing to move rightward. In other words, the two adjusting devices 40 control the display parts 31 on the two housings 20 to move in opposite directions (as shown by the arrows in Figure 2 ), so as to apply tensile forces in opposite directions to the opposite ends of the display part 31. In this way, when the electronic device 1 is in the unfolded state, the flexible screen 30 is in a taut state, and the taut state can be understood as the state when the opposite ends of the display part 31 in the flexible screen 30 are subjected to tensile forces in opposite directions. When the flexible screen 30 has creases, that is, when the display part 31 on the folding device 10 is folded, the opposite ends of the display part 31 on the folding device 10 will also be subjected to tensile forces in opposite directions, thereby tightening the display part 31 in this area, reducing the depth and light and shadow of the creases, making the flexible screen 30 taut and improving the flatness of the bending area, and improving the flatness of the flexible screen 30 in the flattened state.

[0046] During the folding process of the electronic device 1, the two adjusting devices 40 can drive the display parts 31 on the two housings 20 to move towards each other (as shown by the arrows in Figure 5 ). In other words, the adjusting device 40 located in the left housing can drive the display part 31 on the left housing to move rightward, and the adjusting device 40 located in the right housing can drive the display part 31 on the right housing to move leftward. In this way, the two adjusting devices 40 no longer apply tensile forces to the opposite sides of the display part 31. Similarly, the opposite sides of the display part 31 on the folding device 10 are no longer subjected to tensile forces, that is, the pulling on the flexible screen 30 is relaxed. It ensures the relative relaxation of the flexible screen 30 in the bending area during the folding process, does not add additional extrusion or pulling to the flexible screen 30, enables the flexible screen 30 to be bent normally, and improves the protection of the flexible screen 30. When the electronic device 1 is in the folded state, the flexible screen 30 can be in a relaxed state, enabling the flexible screen 30 to achieve the best water droplet shape. The relaxed state can also be understood as the state when the adjusting device 40 does not apply tensile force to the flexible screen 30, and the best water droplet shape generally refers to the bending shape with the smallest bending stress on the functional layer of the flexible screen 30.

[0047] It should be noted that the "capable" mentioned above only represents that the driving member 41 in the adjusting device 40 has a tendency to control the movement of the driven mechanism 42. However, whether the driven mechanism 42 actually moves depends on whether the flexible screen 30 has creases. When the flexible screen 30 has not yet developed creases, regardless of whether the electronic device 1 is folded or unfolded, the adjusting device 40 will not drive the flexible screen 30 to move, that is, the driving member 41 will not drive the driven mechanism 42 to move. However, at this time, a pulling force will still be generated in the unfolded state, which can reduce the probability and time of crease formation. Only when the flexible screen 30 has creases will the adjusting device 40 drive the flexible screen 30 to move, that is, the driving member 41 will drive the driven mechanism 42 to move, thereby driving the flexible screen 30 to move.

[0048] In summary, this embodiment utilizes the characteristics that the electronic device 1 can move during the bending process and has relatively high stiffness along the tangential direction to design an adjustable electronic device 1. Through the user's action of opening and closing the whole machine, the adjusting device 40 pulls the flexible screen 30 during the unfolding process, and the flexible screen 30 in the flattened state is tightened, improving the flatness of the flexible screen 30 in the bending area in the unfolded state and reducing the crease light and shadow in the bending area. During the entire folding process, the flexible screen 30 is relaxed, protecting the flexibility of the flexible screen 30 in the bending area in the folded state.

[0049] The adjusting device 40 mainly consists of two parts: a driving member 41 and a driven mechanism 42. One end of the driven mechanism 42 is connected to the driving member 41, and the other end is fixed to the flexible screen 30. Optionally, one end of the driven mechanism 42 can be fixed to the driving member 41, or one end of the driven mechanism 42 can be rotatably connected to the driving member 41. The driving member 41 is rod-shaped and is used to control the movement of the driven mechanism 42. Therefore, the driving member 41 can also be called a driving rod. The driving member 41 itself can move, so the driving member 41 can drive the driven mechanism 42 to move together. Since the other end of the driven mechanism 42 is fixed to the flexible screen 30, the driven mechanism 42 can drive the flexible screen 30 to move together, ultimately achieving the purpose of the adjusting device 40 driving the flexible screen 30 to move. The specific structure of the driven mechanism 42 is not limited in this embodiment, and any structure that can drive the flexible screen 30 to move under the movement of the driving member 41 should fall within the protection scope of this application.

[0050] It should be noted that the driving member 41 can be an active driving member 41. For example, a motor can be used to actively move the driving member 41. In other embodiments, the driving member 41 can also be a passive driving member 41, that is, the driving member 41 itself does not move actively, but during the movement of the electronic device 1, the driving member 41 cooperates with other components to drive the driving member 41 to move, enabling the driving member 41 to move adaptively. This embodiment only uses the driving member 41 as a passive driving member 41 for illustrative purposes.

[0051] Specifically, during the unfolding process of the electronic device 1, the driving member 41 moves in the first direction, and thus can control the driven mechanism 42 to drive the display portion 31 on the corresponding housing 20 to move in a direction away from the display portion 31 on the other housing 20, so that the display portions 31 on the two housings 20 move away from each other. Optionally, the first direction can be left or right. For example, the driving member 41 moves to the left and thus controls the driven mechanism 42 to drive the display portion 31 to move to the left. Or, the driving member 41 moves to the right and thus controls the driven mechanism 42 to drive the display portion 31 to move to the left. In addition, the first direction is perpendicular to the axis direction, so the first direction is the width direction of the folding device 10.

[0052] During the folding process of the electronic device 1, the driving member 41 moves in the second direction opposite to the first direction, and thus can control the driven mechanism 42 to drive the display portion 31 on one housing 20 to move in a direction close to the display portion 31 on the other housing 20, so that the display portions 31 on the two housings 20 move towards each other. Optionally, when the first direction is left, the second direction is right, and when the first direction is right, the second direction is left. For example, the driving member 41 moves to the right and thus controls the driven mechanism 42 to drive the display portion 31 to move to the right, or, the driving member 41 moves to the left and thus controls the driven mechanism 42 to drive the display portion 31 to move to the right. In summary, in this embodiment, by controlling the movement of the driving member 41, the flexible screen 30 can be driven by the driven mechanism 42 to move in a preset direction.

[0053] In this embodiment, the electronic device 1 further includes an adhesive layer 50 bonded between the housing 20 and the display portion 31. During the unfolding process of the electronic device 1, the adhesive layer 50 undergoes shear deformation. During the folding process of the electronic device 1, the adhesive layer 50 returns to its original state.

[0054] The display part 31 of the flexible screen 30 can be bonded to the housing 20 through the bonding layer 50. The display part 31 is made of foam adhesive or pure adhesive material and can be misaligned in the moving direction of the display part 31. The misalignment can be understood as the deformation displacement of the bonding layer 50 along the moving direction of the flexible screen 30 under the shear stress applied by the flexible screen 30. During the unfolding process of the electronic device 1, the two adjusting devices 40 cause the display parts 31 on the two housings 20 to move away from each other. However, since the housing 20 does not move, at this time, the bonding layer 50 is misaligned and deformed along the moving direction of the corresponding display part 31, so as to realize the slight misalignment between the display part 31 and the housing 20, and make the display part 31 closely adhere to the surface of the housing 20. Thus, when the electronic device 1 is in the unfolded state, the flexible screen 30 is in a relatively taut state, improving the flatness of the flexible screen 30. During the folding process of the electronic device 1, the adjusting device 40 causes the display part 31 to move in the reverse direction, so that the bonding layer 50 returns to its original state, relaxing the pulling force on the flexible screen 30, ensuring the relative relaxation of the flexible screen 30 in the bending area during the folding process, and enabling the flexible screen 30 to be bent normally. In summary, in this embodiment, by providing the bonding layer 50, the display part 31 can realize slight misalignment with the housing 20 on the basis of being fixed to the housing 20.

[0055] The specific structure and movement principle of the adjusting device 40 will be introduced in detail below in this application. Since the folding device 10 is provided with the housing 20, the adjusting device 40, and the flexible screen 30 on both opposite sides, and the movement principles on both sides are the same but in opposite directions, only the structure on the left side when the folding device 10 is in the unfolded state will be schematically described below in this application. As for the structure on the right side of the folding device 10, it can be understood by referring to the structure on the left side.

[0056] Please refer to Figure 6 , in this embodiment, the adjusting device 40 penetrates the housing 20 and is fixed to the side of the flexible screen 30 facing away from its display surface 300. It is mentioned above that the adjusting device 40 can be fixed to the flexible screen 30 to drive the flexible screen 30 to move. In this embodiment, the adjusting device 40 can be directly fixed to the flexible screen 30 on the housing 20. Specifically, through holes 200 can be opened on the housing 20 and the bonding layer 50 to enable the adjusting device 40 to penetrate the housing 20 and the bonding layer 50 and be directly fixed to the side of the flexible screen 30 facing away from its display surface 300, that is, fixed below the flexible screen 30. In other words, it can be directly fixed to the back of the display part 31 of the flexible screen 30, so that the moving direction of the adjusting device 40 is the moving direction of the flexible screen 30 and the display part 31.

[0057] Please refer to Figure 7, in this embodiment, the flexible screen 30 further includes a non-display portion 32 connected to the edge of the display portion 31. The non-display portion 32 is wound into the housing 20 and fixed to the adjusting device 40. During the unfolding process of the electronic device 1, the adjusting device 40 can drive the non-display portion 32 to move in a direction close to the display portion 31 of another housing 20.

[0058] The flexible screen 30 may also include the non-display portion 32 mentioned above, but the non-display portion 32 and the display portion 31 are not provided on the same side. The display portion 31 is provided above the two housings 20 and the folding device 10. The non-display portion 32 is bent and wound into the interior of the housing 20 and fixedly connected to the adjusting device 40, so that the non-display portion 32 and the display portion 31 are arranged opposite to each other. In this way, the adjusting device 40 can first drive the non-display portion 32 to move, and then drive the display portion 31 to move through the non-display portion 32, which can not only increase the display area and the screen-to-body ratio, but also reduce the fixing difficulty.

[0059] Optionally, the ways of the adjusting devices 40 on the left and right sides to fix the flexible screen 30 may be the same or different. For example, the non-display portion 32 of the flexible screen 30 on the left side is bent into the interior of the housing 20 to be fixedly connected to the adjusting device 40, and the adjusting device 40 on the right side can directly penetrate the right housing 20 to be fixedly connected to the back of the display portion 31. This embodiment is only schematically described with left and right symmetry.

[0060] It should be noted that, as Figure 7 shown by the arrow in, the moving directions of the non-display portion 32 and the display portion 31 are different. If the non-display portion 32 moves to the right, the display portion 31 on the same side moves to the left; if the non-display portion 32 moves to the left, the display portion 31 on the same side moves to the right. In other words, the moving direction of the flexible screen 30 is not unique, and different regions have different moving directions. Therefore, it is mentioned above that the display portions 31 on the two housings 20 move away from each other, and at this time, the two non-display portions 32 move towards each other.

[0061] In this embodiment, the electronic device 1 further includes a rotating member 51 provided on the housing 20. The non-display portion 32 is wound into the housing 20 through the rotating member 51, and when the non-display portion 32 moves, the rotating member 51 rotates around its axis. The rotating member 51 can also be added to the housing 20, and the rotating member 51 can rotate around its own axis. At this time, the rotating member 51 can also be called a rotating roller. The non-display portion 32 can be wound into the interior of the housing 20 through the rotating member 51, so that the rotating member 51 meshes with the inner side of the non-display portion 32. During the unfolding and folding processes of the whole machine, when the non-display portion 32 moves, the rotating member 51 rotates passively, and the static friction force exists between the two, thereby reducing the movement difficulty of the non-display portion 32. Optionally, the material of the rotating member 51 is soft rubber, which can further improve the cooperation effect between the rotating member 51 and the non-display portion 32.

[0062] In this embodiment, one end of the driving member 41 penetrates through the housing 20 and abuts against the folding device 10, and the other end is connected to one end of the driven mechanism 42. When the driving member 41 cooperates with the folding device 10 to expand or fold the electronic device 1, the driving member 41 moves in the first direction or the second direction.

[0063] Part of the driving member 41 can be disposed inside the housing 20, with one end thereof penetrating through the housing 20 and abutting against the folding device 10, and the other end being connected to one end of the driven mechanism 42. Optionally, one end of the driving member 41 can abut against the decorative member 11 of the folding device 10. The decorative member 11 is a component for installing the base in the folding device 10, which can shield the components of the folding device 10, and the decorative member 11 can also serve as the appearance surface of the electronic device 1. When the folding device 10 moves, the decorative member 11 is stationary, but the housing 20 rotates relative to the decorative member 11. At this time, the housing 20 will drive the driving member 41 to rotate together. Since one end of the driving member 41 abuts against the decorative member 11, one end of the driving member 41 can rotate relative to the decorative member 11, so as to realize the movement of the driving member 41 by the mutual cooperation between one end of the driving member 41 and the decorative member 11. Of course, in other embodiments, one end of the driving member 41 can also abut and cooperate with other components of the folding device 10. At this time, the driving member 41 can be called the driven driving member 41, and the driving member 41 can move adaptively during the movement of the electronic device 1. The electronic device 1 can also be called an adaptive electronic device for improving creases.

[0064] Moreover, in the two processes of folding or unfolding the electronic device 1, in one movement process, one end of the driving member 41 cooperates with the folding device 10 to realize adaptive movement, and in the other movement process, the driving member 41 can move in the opposite direction. Optionally, the driving member 41 can also move adaptively in the reverse direction through other components. Specifically, during the unfolding process of the electronic device 1, the driving member 41 cooperates with the folding device 10 to make the driving member 41 move in the first direction. During the folding process of the electronic device 1, the driving member 41 can move in the second direction. Or, during the unfolding process of the electronic device 1, the driving member 41 can move in the first direction. During the folding process of the electronic device 1, the driving member 41 cooperates with the folding device 10 to make the driving member 41 move in the second direction. In summary, in this embodiment, by making the driving member 41 cooperate with the folding device 10, the driving member 41 can move adaptively, without the need to provide an additional power source, which simplifies the structure of the electronic device 1.

[0065] Please refer to Figures 8-9, In an embodiment, the folding device 10 includes a decorative member 11. The decorative member 11 includes a bottom wall 111 and two side walls 112 that are bent and connected to opposite sides of the bottom wall 111. In the direction from near the bottom wall 111 to far from the bottom wall 111, the distance between the two outer side surfaces 1120 of the two side walls 112 gradually increases or decreases. When the distance between the two outer side surfaces 1120 gradually increases, during the folding process of the electronic device 1, the other end of the driving member 41 moves in a direction away from the decorative member 11. Or, when the distance between the two outer side surfaces 1120 gradually decreases, during the unfolding process of the electronic device 1, the other end of the driving member 41 moves in a direction away from the decorative member 11.

[0066] The decorative member 11 is a U-shaped component. Specifically, the decorative member 11 is formed by bending a bottom wall 111 and two side walls 112 that are bent and connected to opposite sides of the bottom wall 111. The base in the folding device 10 can be installed on the bottom wall 111, and the two side walls 112 are used to wrap and block the bottom wall 111, and cooperate with the two side housings 20 on the left and right to form a smooth outer curve in the folded state. The two opposite surfaces of the two side walls 112 are the outer side surfaces 1120 of the side walls 112. In this embodiment, the distance between the two outer side surfaces 1120 can be unequal up and down. Specifically, in the direction from near the bottom wall 111 to far from the bottom wall 111, that is, in the direction from bottom to top, the distance between the two outer side surfaces 1120 gradually increases or decreases. Optionally, the outer side surface 1120 can be an inclined surface or a curved surface.

[0067] It should be noted that the change in the distance between the two inner side surfaces when the distance between the two outer side surfaces 1120 gradually changes is not limited in this embodiment and can be designed according to requirements. For example, it can remain unchanged, increase, or decrease. In other words, in this embodiment, it is only necessary to control the gradual change in the distance between the two outer side surfaces 1120, and the side wall 112 itself is not limited.

[0068] When the electronic device 1 is an in-foldable electronic device 1, when the electronic device 1 is folded, the two housings 20 will rotate from opposite sides of the decorative member 11 to above the decorative member 11, that is, the two housings 20 move from bottom to top in the vertical direction, resulting in the driving member 41 also moving from bottom to top. In other words, in the unfolded state, one end of the driving member 41 abuts against the lower side of the decorative member 11, and in the folded state, one end of the driving member 41 abuts against the upper side of the decorative member 11.

[0069] Therefore, when the distance between the two outer side surfaces 1120 gradually increases, that is, the two outer side surfaces 1120 are narrower at the bottom and wider at the top, at this time, during the folding process of the electronic device 1, one end of the driving member 41 gradually moves from the lower side to the upper side. Since it is wider upwards, the other end of the driving member 41 will move in a direction away from the decorative member 11. For example, the driving member 41 moves to the left as a whole, and then controls the movement of the flexible screen 30 through the driven mechanism 42.

[0070] When the distance between the two outer sides 1120 gradually decreases, that is, the two outer sides 1120 are wider at the bottom and narrower at the top, during the unfolding process of the electronic device 1, one end of the driving member 41 gradually moves from the upper side to the lower side. Since it is wider towards the bottom, the other end of the driving member 41 will move in a direction away from the decorative member 11. For example, the driving member 41 moves leftward as a whole, and then controls the movement of the flexible screen 30 through the driven mechanism 42. As for the specific direction in which the driving member 41 needs to move during the folding process, multiple factors need to be considered together, such as the specific structure of the driven mechanism 42, the position where the driven mechanism 42 fixes the flexible screen 30, etc. The user can make a choice according to the actual situation. In summary, in this embodiment, by gradually changing the distance between the two outer sides 1120, the moving direction of the driving member 41 can be controlled.

[0071] Please refer to again Figure 7 In this embodiment, a holding portion 21 is fixedly provided in the housing 20. The driving member 41 passes through the holding portion 21, and a boss 411 is provided on the periphery of the driving member 41. The adjusting device 40 further includes an elastic member 43 sleeved on the driving member 41 and disposed between the boss 411 and the holding portion 21. When the distance between the two outer sides 1120 gradually increases, during the folding process of the electronic device 1, the elastic member 43 is in a deformed state, and during the unfolding process of the electronic device 1, the elastic member 43 drives the other end of the driving member 41 to move in a direction close to the decorative member 11. Or, when the distance between the two outer sides 1120 gradually decreases, during the unfolding process of the electronic device 1, the elastic member 43 is in a deformed state, and during the folding process of the electronic device 1, the elastic member 43 drives the other end of the driving member 41 to move in a direction close to the decorative member 11.

[0072] Inside the housing 20, a holding portion 21 can also be provided for the driving member 41 to pass through. It can not only be used to install the driving member 41, but also restrict the moving direction of the driving member 41 through the holding portion 21. Optionally, the housing 20 and the holding portion 21 can be of an integral structure or a split structure. Moreover, a boss 411 can be protruded on the periphery of the driving member 41, so that the diameter at the boss 411 is larger than the diameter of the driving member 41. In addition, in this embodiment, an elastic member 43 can be added on the basis of the driving member 41 and the driven member 44. The elastic member 43 is sleeved on the driving member 41, and the elastic member 43 is arranged between the boss 411 and the holding portion 21, so that the opposite ends of the elastic member 43 are respectively arranged on the boss 411 and the holding portion 21. For example, one end of the elastic member 43 is arranged on the boss 411, and the other end is arranged on the holding portion 21. Optionally, the opposite ends of the elastic member 43 can be fixed to the boss 411 and the holding portion 21, or the opposite ends of the elastic member 43 can be abutted against the boss 411 and the holding portion 21. The connection relationship between the elastic member 43 and the boss 411 and the holding portion 21 is related to the type of the elastic member 43. When the elastic member 43 is a compression spring, it can be either fixed or abutted. When the elastic member 43 is a tension spring, the elastic member 43 needs to be fixed to the boss 411 and the holding portion 21.

[0073] As can be seen from the above, the distance between the two outer side surfaces 1120 can gradually increase or gradually decrease. When the distance between the two outer side surfaces 1120 gradually increases, during the folding process of the electronic device 1, the driving member 41 moves adaptively. At this time, the elastic member 43 can be in a deformed state, that is, the elastic member 43 undergoes elastic deformation, such as a compressed state or a stretched state. Therefore, during the unfolding process of the electronic device 1, the elastic member 43 in the deformed state can use the rebound force to drive the boss 411 to move the other end of the driving member 41 in the direction close to the decorative member 11, that is, control the driving member 41 to move adaptively in the reverse direction, so that the driving member 41 still abuts against the decorative member 11 during the unfolding process, thereby providing a basis for the movement during the next folding.

[0074] Similarly, when the distance between the two outer side surfaces 1120 gradually decreases, during the unfolding process of the electronic device 1, the driving member 41 moves adaptively. At this time, the elastic member 43 can be in a deformed state, that is, the elastic member 43 undergoes elastic deformation, such as a compressed state or a stretched state. During the folding process of the electronic device 1, the elastic member 43 in the deformed state can use the rebound force to drive the boss 411 to move the other end of the driving member 41 in the direction close to the decorative member 11, that is, control the driving member 41 to move adaptively in the reverse direction, so that the driving member 41 still abuts against the decorative member 11 during the folding process, thereby providing a basis for the movement during the next unfolding.

[0075] In summary, in this embodiment, through the cooperation of the decorative member 11 and the elastic member 43, the driving member 41 can achieve adaptive movement during the unfolding and folding processes, thereby controlling the movement direction of the driving member 41. Specifically, the decorative member 11 is used to move the driving member 41 to the left, and the elastic member 43 is used to move the driving member 41 to the right. The user can choose whether to fold to the left during the unfolding process and to the right during the folding process, or fold to the right during the unfolding process and to the left during the folding process according to actual needs.

[0076] In this embodiment, when the deformation state is the compression state, the abutting portion 21 is farther from the decorative member 11 than the boss 411. When the deformation state is the tensile state, the abutting portion 21 is closer to the decorative member 11 than the boss 411.

[0077] The elastic member 43 can be a compression spring or a tension spring. When the elastic member 43 is a compression spring, the deformation that occurs is compression. When the elastic member 43 is a tension spring, the deformation that occurs is tension. And different types of the elastic member 43 result in different relative positions of the abutting portion 21 and the boss 411. For example, when the deformation state is the compression state, at this time, the abutting portion 21 can be made farther from the decorative member 11 than the boss 411, that is, the fixed abutting portion 21 is arranged on the left, and the boss 411 that can move with the driving member 41 is arranged on the right. In this way, the elastic member 43 in the compression state can drive the boss 411 to move to the right, thereby moving the driving member 41 to the right, that is, moving the other end of the driving member 41 in the direction close to the decorative member 11.

[0078] When the deformation state is the tensile state, at this time, the abutting portion 21 can be made closer to the decorative member 11 than the boss 411, that is, the fixed abutting portion 21 is arranged on the right, and the boss 411 that can move with the driving member 41 is arranged on the left. In this way, the elastic member 43 in the tensile state can drive the boss 411 to move to the left, thereby moving the driving member 41 to the left, that is, moving the other end of the driving member 41 in the direction close to the decorative member 11.

[0079] In summary, in this embodiment, the position between the abutting portion 21 and the boss 411 can be selected according to the type of the elastic member 43, so as to use the elastic member 43 to make the other end of the driving member 41 adaptively move in the direction close to the decorative member 11. It should be noted that the positions of the abutting portion 21 and the boss 411 are only related to the type of the elastic member 43 and have nothing to do with the change in the distance between the two outer sides 1120.

[0080] In this embodiment, the opposite ends of the driven mechanism 42 are respectively fixed to the driving member 41 and the flexible screen 30. When the driving member 41 moves, it can drive the driven mechanism 42 to move, and then drive the flexible screen 30 to move.

[0081] Based on the detailed description of the movement principle of the driving member 41 above, the present application provides various specific embodiments of the driven mechanism 42. In the first embodiment, the driven mechanism 42 can be only one component, and the opposite ends of the driven mechanism 42 are respectively fixed to the driving member 41 and the flexible screen 30, that is, one end of the driven mechanism 42 is fixed to the driving member 41, and the other end is fixed to the flexible screen 30. In this way, the movement of the driving member 41 can be synchronized to the flexible screen 30 through the driven mechanism 42. If the driving member 41 moves to the left, the display portion 31 of the flexible screen 30 can move to the left synchronously. If the driving member 41 moves to the right, the display portion 31 of the flexible screen 30 can move to the right synchronously, which can simplify the structure of the driven mechanism 42.

[0082] The driven mechanism 42 includes a connecting rod or a connecting rope 412. Optionally, the connecting rope 412 can be made of a flexible material. The flexible material has high stiffness in the stretching direction and low elongation. Specifically, it can be an organic polymer material, such as PE, PET, etc. During the flattening process, the movement of the driving member 41 tightens the flexible material and pulls the display portion 31 to move to the left, realizing the tightening function. During the folding process, the movement of the driving member 41 relaxes the flexible material and no longer applies a pulling force to the flexible screen 30. In summary, in the first embodiment, only by fixing the two ends of the driven mechanism 42 to the driving member 41 and the flexible screen 30, the flexible screen 30 can be driven to move under the control of the driving member 41.

[0083] Please refer to Figure 10 , in this embodiment, the driven mechanism 42 includes a gear 421 rotatably connected to the driving member 41 and a rack 422 meshing with the gear 421. The rack 422 is fixed to the flexible screen 30. When the driving member 41 moves, it can drive the gear 421 to rotate, and the gear 421 drives the rack 422 to move, thereby driving the flexible screen 30 to move.

[0084] In the second embodiment, the driven mechanism 42 includes a gear 421 and a rack 422. The gear 421 is rotatably connected to the driving member 41, and the rack 422 meshes with the gear 421 and is fixed to the flexible screen 30. When the driving member 41 moves, it can drive the gear 421 to rotate. The rotating gear 421 meshes with the rack 422 to move the rack 422, thereby driving the flexible screen 30 to move. Optionally, the gear 421 can be rotatably connected inside the housing 20, that is, the rotating shaft of the gear 421 can be arranged inside the housing 20. Optionally, the number of gears 421 can be one or more. For example, one gear 421 is rotatably connected to the driving member 41, and one end of another gear 421 is rotatably connected to one gear 421, and the other end is rotatably connected to the rack 422.

[0085] Specifically, when the number of gears 421 is one, the driving member 41 moves to the left, the gear 421 rotates clockwise, the rack 422 moves to the right, driving the flexible screen 30 fixed thereon to move to the right. When the driving member 41 moves to the right, the gear 421 rotates counterclockwise, the rack 422 moves to the left, driving the flexible screen 30 fixed thereon to move to the left. In summary, in the second embodiment, the flexible screen 30 can also be driven to move under the control of the driving member 41 through the cooperation of the gear 421 and the rack 422.

[0086] In this embodiment, the driving member 41 is provided with a protrusion 413 or a groove 414, and the gear 421 is eccentrically provided with a groove 414 or a protrusion 413 correspondingly. The protrusion 413 is inserted into the groove 414 so that the gear 421 can be driven to rotate when the driving member 41 moves.

[0087] As mentioned above, the driving member 41 can be rotatably connected to the gear 421. The present application provides two specific embodiments. In one embodiment, the driving member 41 can be directly and eccentrically rotatably connected to the gear 421. For example, the driving member 41 can be provided with a protrusion 413 or a groove 414, and the gear 421 is eccentrically provided with a groove 414 or a protrusion 413 correspondingly. When the driving member 41 has a protrusion 413, the gear 421 is eccentrically provided with a groove 414, and when the driving member 41 is provided with a groove 414, the gear 421 is eccentrically provided with a protrusion 413. Eccentric means that the groove 414 or the protrusion 413 of the gear 421 is not provided at the rotation axis of the gear 421, so that the driving member 41 can drive the gear 421 to rotate when it moves.

[0088] Specifically, a rack 422, a gear 421, and a driving member 41 are provided from one side to the other side of the flexible screen 30. At this time, the driving member 41 can be eccentrically rotatably connected below the rotation axis of the gear 421. When the driving member 41 moves to the left, the gear 421 rotates clockwise, the rack 422 moves to the right, driving the flexible screen 30 fixed thereon to move to the right. When the driving member 41 moves to the right, the gear 421 rotates counterclockwise, the rack 422 moves to the left, driving the flexible screen 30 fixed thereon to move to the left. In summary, in one embodiment, the driving member 41 can directly control the rotation of the gear 421 through eccentric connection.

[0089] Please refer to Figure 11, in this embodiment, another rack portion 415 meshing with the gear 421 is provided on the driving member 41, so that when the driving member 41 moves, the gear 421 is driven to rotate. In another embodiment, a rack portion 415 can be additionally provided on the driving member 41. In this way, when the driving member 41 moves, the rack portion 415 can be driven to move. The rack portion 415 meshes with the gear 421 to drive the gear 421 to rotate, and the gear 421 meshes with the rack 422 to drive the rack 422 to move, thereby driving the flexible screen 30 to move. Optionally, the driving member 41 and the rack portion 415 can be an integral structure or a split structure.

[0090] Specifically, when the driving member 41 moves to the left, the rack portion 415 moves to the left, the gear 421 rotates clockwise, the rack 422 moves to the right, and the flexible screen 30 fixed thereon is driven to move to the right. When the driving member 41 moves to the right, the rack portion 415 moves to the right, the gear 421 rotates counterclockwise, the rack 422 moves to the left, and the flexible screen 30 fixed thereon is driven to move to the left. In summary, in another embodiment, the rotation of the gear 421 can be controlled by setting the rack portion 415.

[0091] Please refer to Figure 12 , in this embodiment, the driven mechanism 42 includes a driven member 44 rotatably connected to the driving member 41, a gear 421 slidably connected to the driven member 44, and a rack 422 meshing with the gear 421. The rack 422 is fixed to the flexible screen 30. When the driving member 41 moves, the driven member 44 and the gear 421 are driven to rotate, and the driven member 44 also slides relative to the gear 421. The gear 421 drives the rack 422 to move, thereby driving the flexible screen 30 to move.

[0092] In the third embodiment, the driven mechanism 42 can be provided with a driven member 44 on the basis of the gear 421 and the rack 422. The driven member 44 is not only rotatably connected to the driving member 41 but also slidably connected to the gear 421. At this time, there is no connection relationship between the gear 421 and the driving member 41. The gear 421 only meshes with the rack 422, and the rack 422 is fixed to the flexible screen 30. In this way, when the driving member 41 moves, the driven member 44 can be driven to rotate relative to the driving member 41. Since the driven member 44 is movably connected to the gear 421, the rotating driven member 44 can drive the gear 421 to rotate synchronously, and the driven member 44 will also slide relative to the gear 421 to adjust the distance between the rotating axes of the driven member 44 and the gear 421 to prevent interference. The rotation of the gear 421 can drive the rack 422 to move and finally drive the flexible screen 30 fixed thereon to move.

[0093] Specifically, when the driving member 41 moves to the left, the driven member 44 and the gear 421 both rotate clockwise, and the driven member 44 slides relative to the gear 421. The rack 422 moves to the right, driving the flexible screen 30 fixed thereon to move to the right. When the driving member 41 moves to the right, the driven member 44 and the gear 421 both rotate counterclockwise, and the driven member 44 slides relative to the gear 421. The rack 422 moves to the left, driving the flexible screen 30 fixed thereon to move to the left. In summary, in the third embodiment, the flexible screen 30 can also be driven to move under the control of the driving member 41 through the cooperation of the driven member 44, the gear 421, and the rack 422.

[0094] In addition, the driven mechanism 42 may further include a fixing member 45. The fixing member 45 can be used to fix the flexible screen 30. At the same time, structures such as the rack 422 can be directly disposed on the fixing member 45. In addition, the fixing member 45 can move within the housing 20 so that when the rack 422 moves, the fixing member 45 is driven to move, thereby driving the flexible screen 30 fixed thereon to move.

[0095] Please refer to Figure 13 , the movement principle of the adjusting device 40 in this embodiment can also be simplified as follows: The driving member 41 and the outer side surface 1120 of the decorative member 11 form a cam pair, the driving member 41 and the housing 20 form a sliding pair, and the lateral movement of the driving member 41 is controlled through the cam pair and the sliding pair. The driving member 41 and the driven member 44 form a rotating pair, the driven member 44 and the gear 421 form a sliding pair, and the rotation of the gear 421 is controlled through the rotating pair and the sliding pair. The gear 421 and the housing 20 form a rotating pair, the gear 421 and the rack 422 form a gear 421 pair, and the movement of the rack 422 is controlled through the rotating pair and the gear 421 pair. The rack 422 and the housing 20 form a sliding pair, and through the sliding pair, the rack 422 can drive the flexible screen 30 fixed thereon to move synchronously, controlling the tension or relaxation of the flexible screen 30.

[0096] In this embodiment, for example, when the left electronic device 1 is folded, the driving member 41 rotates clockwise relative to the decorative member 11. The cam pair and the sliding pair drive the driving member 41 to move to the right. The driven member 44 and the gear 421 rotate counterclockwise, and the rack 422 moves to the left. Therefore, the end of the non-display portion 32 of the flexible screen 30 fixed on the rack 422 also moves to the left. In other words, the display portion 31 on the left moves to the right. Similarly, when the right electronic device 1 is folded, the driving member 41 rotates counterclockwise relative to the decorative member 11. The cam pair and the sliding pair drive the driving member 41 to move to the left. The driven member 44 and the gear 421 rotate clockwise, and the rack 422 moves to the right. Therefore, the end of the non-display portion 32 of the flexible screen 30 fixed on the rack 422 also moves to the right. In other words, the display portion 31 on the right moves to the left, realizing the opposite movement of the display portions 31 on the two housings 20, making the flexible screen 30 tend to relax. Thus, the bending area of the flexible screen 30 is relaxed in the folded state, improving the service life.

[0097] Conversely, when the electronic device 1 on the left is unfolded, the driving member 41 rotates counterclockwise relative to the decorative member 11, the elastic member 43 drives the driving member 41 to move leftward, the driven member 44 and the gear 421 rotate clockwise, and the rack 422 moves rightward. Therefore, the end of the non-display portion 32 of the flexible screen 30 fixed on the rack 422 also moves rightward. In other words, the display portion 31 on the left moves leftward. Similarly, when the electronic device 1 on the right is unfolded, the driving member 41 rotates clockwise relative to the decorative member 11, the elastic member 43 drives the driving member 41 to move rightward, the driven member 44 and the gear 421 rotate counterclockwise, and the rack 422 moves leftward. Therefore, the end of the non-display portion 32 of the flexible screen 30 fixed on the rack 422 also moves leftward. In other words, the display portion 31 on the right moves rightward, realizing the back-to-back movement of the display portions 31 on the two housings 20. The above process makes the flexible screen 30 tend to be tightened, so as to tighten the flexible screen 30 in the unfolded state and optimize the creases in the bending area of the flexible screen 30.
