Description

A bamboo book, screen assembly and electronic device Technical Field

[0001] This application relates to the field of electronic device technology, and more particularly to a bamboo book, a screen assembly, and an electronic device. Background Technology

[0002] Foldable electronic devices are prone to screen creases during prolonged use. The bottom of the screen assembly typically features a bamboo-like structure that, when the device is folded, helps to constrain the screen into a teardrop shape, reducing crease depth and improving overall screen reliability. However, in actual use, the bamboo structure cannot completely maintain the intended teardrop shape. Summary of the Invention

[0003] The purpose of this application is to provide a bamboo book, a screen assembly, and an electronic device to solve the technical problem in the prior art that the bamboo book cannot completely constrain the screen into a preset teardrop shape.

[0004] In a first aspect, embodiments of this application provide a bamboo book for use in electronic devices. The bamboo book has a connected body segment, a first support segment, and a second support segment. The thicknesses of the first support segment, the second support segment, and the body segment are all different, so that a portion of the bamboo book's structure is teardrop-shaped when bent.

[0005] In this embodiment, by dividing the bamboo book into sections of varying thicknesses, the structural rigidity of different areas of the bamboo book can be altered to meet the usage requirements of different areas. When the electronic device is in a folded state, the area corresponding to the foldable portion of the bamboo book and the screen module automatically forms a preset teardrop shape. This allows the foldable portion to form a preset teardrop shape under the constraint of the bamboo book, reducing the bending pressure on the foldable portion and significantly reducing the crease depth formed after prolonged use, thus improving the user experience. The main body section, the first support section, and the second support section can be integrally molded, offering advantages such as simple structure and ease of implementation.

[0006] In one specific embodiment, the first support segment is used to form an inwardly curved shape at the bottom of the teardrop shape, and the second support segment is used to form an outwardly curved shape at the top of the teardrop shape.

[0007] In this embodiment, under the combined action of the first support section and the second support section, when the electronic device is in a folded state, part of the bamboo book's structure can automatically form a teardrop shape in a bent state, meeting the usage requirements.

[0008] In one specific embodiment, the bamboo book has two second support segments symmetrically arranged along the width direction of the electronic device in a flattened state, and the two second support segments are respectively connected to both sides of the first support segment. The bamboo book also has two body segments symmetrically arranged along the width direction of the electronic device in a flattened state, and the two body segments are respectively connected to the ends of the two second support segments that are far apart from each other.

[0009] In this embodiment, when the bamboo book is flattened, the first support segment is directly connected to the side of the two second support segments that are close to each other, so that the two second support segments are both first support segments with the same thickness, which is convenient for processing and can improve the flatness of the foldable part.

[0010] In one specific embodiment, the bamboo book has two second support segments symmetrically arranged along the width direction of the electronic device in a flattened state. The two second support segments are respectively located on both sides of the first support segment. The first support segment and the second support segment are connected through the body segment. The bamboo book also has two body segments symmetrically arranged along the width direction of the electronic device in a flattened state. The two body segments are respectively connected to the ends of the two second support segments that are far apart from each other.

[0011] In this embodiment, by setting two second support sections symmetrically along the width direction of the electronic device, the two connectors located on both sides of the base can press the two second support sections respectively, thereby enabling the bamboo book to form a teardrop-shaped outward curve on both sides to meet the usage requirements.

[0012] In one specific embodiment, the first support segment is provided with at least one through hole, and / or the second support segment is provided with at least one blind hole.

[0013] In this embodiment, the through-hole structure on the first support section further optimizes the stiffness distribution of the first support section, enabling it to automatically form a teardrop-shaped inward bend when the bamboo book is bent. Simultaneously, the blind-hole structure on the second support section further optimizes its stiffness distribution, allowing it to form a teardrop-shaped outward bend under the pressure of the connector, and enabling control over the angle of the outward bend to meet usage requirements.

[0014] In one specific embodiment, the thickness L1 of the body segment, the thickness L2 of the first support segment, and the thickness L3 of the second support segment satisfy the following relationship: L1 <L2<L3。

[0015] In this embodiment, the first support segment is made thicker so that it can function as a flexible support plate in related technologies. When the electronic device is folded, the first support segment can automatically form a teardrop-shaped inward curve. The thickness of the first support segment is also greater than that of the main body segment, which enhances the protection of the foldable part and prevents it from colliding with the hinge mechanism and causing damage. Simultaneously, the second support segment is made to its maximum thickness so that it can abut against the connector. When the electronic device is folded, the connector can directly press the second support segment to form a teardrop-shaped outward curve, eliminating the need for door panels and door panel swing arms. This significantly simplifies the hinge mechanism structure, reduces costs and assembly difficulty, increases screen space, and reduces the possibility of collisions between the foldable part and the hinge mechanism.

[0016] In one specific embodiment, the thickness L1 of the body segment is 0.10mm-0.12mm, the thickness L2 of the first support segment is 0.15mm-0.18mm, and the thickness L3 of the second support segment is 0.6mm-0.8mm.

[0017] In this embodiment, the thickness L1 of the body segment can be 0.10mm-0.12mm, ensuring that the body segment meets the structural strength requirements for use in electronic devices and avoiding the impact on the overall thinness of the screen assembly due to excessive thickness of the body segment. Specific values ​​for the thickness L1 of the body segment can be 0.10mm, 0.11mm, 0.12mm, etc.

[0018] The thickness L2 of the first support segment can be 0.15mm-0.18mm, giving it good bending and support properties, and preventing excessive thickness from affecting the screen space. Specific values ​​for the thickness L2 of the first support segment can be 0.15mm, 0.16mm, 0.17mm, 0.18mm, etc.

[0019] The thickness L3 of the second support section can be 0.6mm-0.8mm, allowing it to abut against the connector. This enables the connector to press the second support section, causing it to form a teardrop-shaped outward bend. It also prevents interference with the rotating shaft mechanism due to excessive thickness of the second support section, which could affect the assembly of the electronic device. Specific values ​​for the thickness L3 of the second support section can be 0.6mm, 0.7mm, 0.8mm, etc.

[0020] Secondly, embodiments of this application provide a screen assembly, the screen assembly comprising: a screen module and a bamboo book, wherein the bamboo book is connected to the bottom surface of the screen module along the thickness direction of the electronic device.

[0021] In this embodiment, when the electronic device is in a folded state, the corresponding area of ​​the foldable part of the bamboo book and the screen module is in a bent state and is teardrop-shaped, thereby constraining the foldable part to a teardrop shape, increasing the bending radius of the foldable part, reducing the bending pressure of the foldable part, and thus reducing the crease depth generated by the foldable part.

[0022] In one specific embodiment, the screen module includes a first display portion, a second display portion, and a foldable portion, the foldable portion being located between the first display portion and the second display portion, the projection of the body segment along the thickness direction of the electronic device corresponding to the first display portion and the second display portion; the projections of the first support segment and the second support segment along the thickness direction of the electronic device corresponding to the foldable portion.

[0023] In this embodiment, the projection of the body segment along the thickness direction of the electronic device corresponds to the first display portion and the second display portion, which increases the connection area between the body segment and the first and second display portions, thereby improving the connection reliability between the screen module and the bamboo book. Furthermore, the projections of the first and second support segments along the thickness direction of the electronic device correspond to the foldable portion, so that the foldable portion can be constrained into a teardrop shape under the combined action of the first and second support segments, thereby reducing the crease depth of the foldable portion after prolonged use.

[0024] In one specific embodiment, the screen assembly has a folded state and a flattened state. When the screen assembly is in the folded state, the bamboo book is in a bent state, and the bamboo book can constrain the foldable portion into a teardrop shape. When the screen assembly is in the flattened state, the bamboo book is in a flattened state, and the bamboo book can support the screen assembly.

[0025] In this embodiment, when the screen assembly is in a folded state, the bamboo book is in a bent state. The first support segment is used to form a teardrop-shaped inward bend, and the second support segment is used to form a teardrop-shaped outward bend. When the screen assembly is in a flattened state, the bamboo book is in a flattened state. The first and second support segments can support the foldable part of the screen module, improving the stability and surface flatness of the foldable part.

[0026] Thirdly, embodiments of this application provide an electronic device, the electronic device comprising: a mid-frame, a hinge mechanism, and a screen assembly, wherein the hinge mechanism is rotatably connected to the mid-frame, and the screen assembly is mounted on the mid-frame and the hinge mechanism.

[0027] In this embodiment, the screen assembly is mounted on the middle frame and the pivot mechanism. When the middle frame rotates around the pivot mechanism, it can drive the screen assembly to move, so as to switch the screen assembly between a flat state and a folded state.

[0028] In one specific embodiment, the electronic device further includes a housing, a mid-frame connected to an end of the housing and perpendicular to the housing, the housing including a first housing and a second housing, and a pivot mechanism connected between the first housing and the second housing.

[0029] In this embodiment, when the electronic device is in a folded state, the middle frame drives the first and second housings to rotate around the pivot mechanism, so that the first and second housings are stacked along the thickness direction of the electronic device. When the electronic device is in a flattened state, the first and second housings are on the same plane and parallel to the length or width direction of the electronic device.

[0030] In one specific embodiment, the rotating shaft mechanism includes a base, a swing arm, and a connector; the swing arm is symmetrically arranged along the base, and one end of the swing arm is rotatably connected to the base; the connector is symmetrically arranged on both sides of the base along the width direction of the electronic device, and there is a gap between the connector and the base; the other end of the swing arm is connected to the connector; and the second support section abuts against the connector.

[0031] In this embodiment, the thickness of the second support segment is maximized so that the second support segment can abut against the connector. When the electronic device is in a folded state, the connector can directly press the second support segment to form a teardrop-shaped outward bend, eliminating the need for door panels and door panel swing arms, which significantly simplifies the structure of the hinge mechanism, reduces costs and assembly difficulty, and increases the screen space, reducing the possibility of collision between the foldable part and the hinge mechanism.

[0032] In one specific embodiment, when the electronic device is in a flattened state, along the thickness direction of the electronic device, the projection of the first support segment covers the gap between the connectors located on both sides of the base, and the projections of the two second support segments respectively cover the connectors located on both sides of the base.

[0033] In this embodiment, when the bamboo book is in a flattened state, and the first support segment is directly connected to the side of the two second support segments that are close to each other, the projection of the first support segment covers the gap between the connectors located on both sides of the base.

[0034] In one specific embodiment, when the electronic device is in a flattened state, along the thickness direction of the electronic device, the projection of the first support segment covers the base, and the projections of the two second support segments respectively cover the connectors located on both sides of the base.

[0035] In this embodiment, when the bamboo book is in a flattened state, the two second support sections are located on both sides of the first support section. When the first support section and the second support section are connected through the body section, the projection of the first support section covers the base.

[0089] As shown in Figure 1, Figure 1 is a schematic diagram of the structure of electronic device 1 in a specific embodiment. Electronic device 1 includes, for example, any device with a foldable screen function such as a mobile phone, tablet computer, personal digital assistant (PDA), laptop computer, in-vehicle computer, foldable display device, foldable display screen, wearable device, etc. This application does not impose special limitations on the specific form of the above-described electronic device 1. For ease of explanation, the following description uses a foldable mobile phone as an example. The electronic device 1 of this application is described below with specific embodiments.

[0090] In this embodiment, the length direction of the electronic device 1 is the X-axis direction in Figure 1, the width direction of the electronic device 1 is the Y-axis direction in Figure 1, and the thickness direction of the electronic device 1 is the Z-axis direction in Figure 1. The electronic device 1 includes a middle frame 13, a hinge mechanism 123, a housing 12, and a screen assembly (not shown in Figure 1). The hinge mechanism 123 is rotatably connected to the middle frame 13, and the screen assembly is mounted on the middle frame 13 and the hinge mechanism 123. The middle frame 13 is located at the end of the housing 12 and is perpendicular to the housing 12. The housing 12 includes a first housing 121 and a second housing 122. When the electronic device 1 is in the folded state shown in Figure 1, the middle frame 13 drives the first housing 121 and the second housing 122 to rotate around the hinge mechanism 123, so that the first housing 121 and the second housing 122 are stacked along the thickness direction Z of the electronic device 1.

[0091] Please also refer to Figure 2, which is a structural schematic diagram of the electronic device 1 in Figure 1 in its flattened state. When the electronic device 1 is in the flattened state, the first housing 121 and the second housing 122 are on the same plane and parallel to the length direction X or width direction Y of the electronic device 1. At the same time, the screen assembly (not shown in Figure 2) is mounted on the middle frame 13 and the pivot mechanism 123. When the middle frame 13 rotates around the pivot mechanism 123, it can drive the screen assembly to move, so as to realize the switching between the flattened state and the folded state of the screen assembly.

[0092] As shown in Figure 2, the screen assembly includes a screen module 111, which includes a first display portion 111a, a second display portion 111b, and a foldable portion 111c. Along the length direction X of the electronic device 1, the foldable portion 111c is located between the first display portion 111a and the second display portion 111b. The first display portion 111a is mounted on a first housing 121, the second display portion 111b is mounted on a second housing 122, and the foldable portion 111c is mounted on a pivot mechanism 123.

[0093] As shown in Figure 3, Figure 3 is a structural schematic diagram of the screen module 111 in the folded state. When the electronic device is in the folded state, the foldable part 111c can form a bent shape, so that the first display part 111a and the second display part 111b on both sides can rotate around the foldable part 111c to be stacked along the thickness direction Z of the electronic device, thereby switching the screen module to the folded state.

[0094] Figure 4 shows a partial structure of the screen assembly 11. Figure 4 is a schematic diagram of the structure of the bamboo book 112′ and the foldable portion 111c in the related art. To reduce the crease depth of the foldable portion 111c after prolonged use, the screen assembly 11 also includes the bamboo book 112′. Along the thickness direction Z of the electronic device 1, the bamboo book 112′ is connected to the bottom surface of the screen module 111. When the electronic device is in a folded state, the corresponding area of ​​the bamboo book 112′ and the foldable portion 111c is in a bent state and is teardrop-shaped, thereby constraining the foldable portion 111c into a teardrop shape, increasing the bending radius of the foldable portion 111c, reducing the bending pressure of the foldable portion 111c, and thus reducing the crease depth generated by the foldable portion 111c. However, in actual use, because the bamboo book 112' has a uniform thickness, the overall structural rigidity of the bamboo book 112' is uniform. When the bamboo book 112' and the corresponding area of ​​the foldable part 111c are bent, it is difficult to completely form the preset teardrop shape. As a result, the foldable part 111c cannot be completely constrained to form the preset teardrop shape, resulting in the bamboo book 112' having a poor effect on reducing the creases of the foldable part 111c.

[0095] To solve the above-mentioned technical problems, as shown in Figure 5, which is a structural schematic diagram of the bamboo book 112 provided in this application in a specific embodiment, this application provides a bamboo book 112, including a body segment 112a, a first support segment 112b, and a second support segment 112c connected together. The thicknesses of the body segment 112a, the first support segment 112b, and the second support segment 112c are all different, so that part of the structure of the bamboo book 112 is teardrop-shaped when bent.

[0096] In this embodiment, by dividing the bamboo book 112 into sections of different thicknesses, the structural rigidity of different areas of the bamboo book 112 can be changed to meet the usage requirements of different areas of the bamboo book 112. When the electronic device is in a folded state, the area corresponding to the foldable part of the bamboo book 112 and the screen module can automatically form a preset teardrop shape, thereby allowing the foldable part to form a preset teardrop shape under the constraint of the bamboo book 112, reducing the bending pressure of the foldable part, significantly reducing the crease depth formed after long-term use, and improving the user experience. Furthermore, the main body section 112a, the first support section 112b, and the second support section 112c can be integrally molded, which has the advantages of simple structure and easy implementation.

[0097] As shown in Figure 6, which is a structural schematic diagram of the bamboo book 112′ and the rotating shaft mechanism 123′ in a specific embodiment of the related technology, when the bamboo book is the existing bamboo book 112′ structure with a uniform overall thickness, in order to ensure the use effect of the bamboo book 112′, the rotating shaft mechanism 123′ also needs to be provided with a door panel 123a′, a door panel swing arm 123b′ and a flexible support plate 123c′. Along the thickness direction Z of the electronic device, the door panel 123a′ covers the top surface of the connector 123d′, one end of the door panel swing arm 123b′ is rotatably connected to the base 123e′, and the other end is connected to the door panel 123a′. The projection of the flexible support plate 123c′ along the thickness direction Z of the electronic device covers the base 123e′, and both ends are fixedly connected to the door panel swing arm 123b′. When the electronic device is in a folded state, the door panel 123a' can press the corresponding area at the top of the bamboo book 112' to form a teardrop-shaped outward curve, and the flexible support plate 123c' can constrain the corresponding area at the bottom of the bamboo book 112' to form a teardrop-shaped inward curve (the inward and outward curves are marked in Figure 6), so that the bamboo book 112' can constrain the foldable area of ​​the screen module 111 to form a teardrop shape.

[0098] Please also refer to Figure 7, which is a structural schematic diagram of the pivot mechanism 123′ in Figure 6. The related technology sets up a door panel 123a′, a door panel swing arm 123b′ and a flexible support plate 123c′, which makes the structure and process of the pivot mechanism 123′ complex. Since the door panel 123a′ extends along the width direction Y of the electronic device and is relatively long, the flatness requirement of the door panel 123a′ is high, and the number of door panel swing arms 123b′ that need to be set is also large, which greatly increases the cost and processing and assembly difficulty, and occupies a large space, resulting in insufficient effective screen space. This can easily cause the screen module 111 to collide with the door panel 123a′, affecting the reliability of the electronic device.

[0099] As shown in Figure 8, which is a schematic diagram of the motion principle of the rotating shaft mechanism in Figure 7, the rotating shaft mechanism includes a rotating mechanism and a pressure plate mechanism. The pressure plate mechanism consists of a door panel 123a′ and a door panel swing arm 123b′. The rotating mechanism controls the movement trajectory of the middle frame, while the pressure plate mechanism presses down on the bamboo book to form a teardrop-shaped outward curve. Although the rotating shaft mechanism in related technologies can solve the technical problem of the bamboo book not being able to completely form a teardrop shape, its structure is complex and has many modules.

[0100] To solve the above technical problems, as shown in Figure 9, which is a structural schematic diagram of the bamboo book 112 in Figure 2 in a specific embodiment, the bamboo book 112 provided in this application embodiment has parts with different thicknesses. The thickness L1 of the body segment 112a, the thickness L2 of the first support segment 112b, and the thickness L3 of the second support segment 112c satisfy the following relationship: L1 <L2<L3。

[0101] Please also refer to Figure 10, which is a structural schematic diagram of the pivot mechanism 123, the bamboo book 112, and the screen module in Figure 1. In this embodiment, the thickness of the first support segment 112b is made larger so that the first support segment 112b can play the role of a flexible support plate in the related technology. When the electronic device is in a folded state, the first support segment 112b can automatically form a teardrop-shaped inward bend. The thickness of the first support segment 112b is greater than the thickness of the body segment 112a, which can improve the protection effect of the first support segment 112b on the foldable part 111c and prevent it from colliding with the pivot mechanism 123 and being damaged. At the same time, the thickness of the second support section 112c is maximized so that the second support section 112c can abut against the connector 123c. When the electronic device is in a folded state, the connector 123c can directly press the second support section 112c to form a teardrop-shaped outward bend, eliminating the need for door panels and door panel swing arms, which significantly simplifies the structure of the hinge mechanism 123, reduces costs and assembly difficulty, and increases the screen space, reducing the possibility of collision between the foldable part 111c and the hinge mechanism 123.

[0102] In the above embodiments, when the bamboo book 112 is in a bent state, the first support segment 112b is used to form a teardrop-shaped inward bend, and the second support segment 112c is used to form a teardrop-shaped outward bend. By adjusting the thickness of the first support segment 112b and the second support segment 112c, the bamboo book 112 can automatically form a preset teardrop shape without the need for pressure plate mechanisms such as door panels and door panel swing arms. This improves the protection of the foldable part 111c by the bamboo book 112, reduces the depth of the creases, and also reduces the cost and assembly difficulty of electronic devices, significantly improving the user experience.

[0103] Please also refer to Figure 11, which is a schematic diagram of the hinge mechanism 123 in Figure 10 in its flattened state. Area H in Figure 11 represents the initial installation position of the door panel swing arm. This simplifies the hinge mechanism structure and provides space for the optimized design of other components. Furthermore, as shown in Figure 12, which is a schematic diagram of the motion principle of the hinge mechanism 123 in Figure 10, the hinge mechanism 123 eliminates the need for a pressure plate mechanism (i.e., the door panel and door panel swing arm), significantly simplifying the structure of the hinge mechanism and reducing cost and assembly difficulty.

[0104] Specifically, as shown in Figures 13 and 14, Figure 13 is a schematic diagram of an electronic device 100' in the related art, and Figure 14 is a schematic diagram of the electronic device 1 provided in this application in a specific embodiment. A comparison of Figures 13 and 14 shows that the bamboo book 112 of the electronic device 1 in this embodiment can function as a flexible support plate and door panel structure in the related art, significantly simplifying the structure of the electronic device and reducing costs. Meanwhile, in this embodiment, as shown in Figure 15, which is a schematic diagram of the rotating shaft mechanism 123 in Figure 10 in a flattened state, when the electronic device is in a flattened state, the first support segment 112b and the second support segment 112c can support the foldable portion 111 of the screen module, improving the stability and surface flatness of the foldable portion 111c.

[0105] In one specific embodiment, as shown in Figure 16, which is a structural schematic diagram of the bamboo book 112 provided in this application in another specific embodiment, the thickness L1 of the body segment 112a can be 0.10mm-0.12mm, so that the body segment 112a meets the structural strength required for use in electronic devices, and can avoid affecting the overall thinness of the screen assembly due to excessive thickness of the body segment 112a. The specific value of the thickness L1 of the body segment 112a can be 0.10mm, 0.11mm, 0.12mm, etc.

[0106] The thickness L2 of the first support segment 112b can be 0.15mm-0.18mm, giving it good bending and support properties, and preventing excessive thickness from affecting the screen space. Specific values ​​for the thickness L2 of the first support segment 112b can be 0.15mm, 0.16mm, 0.17mm, 0.18mm, etc.

[0107] The thickness L3 of the second support section 112c can be 0.6mm-0.8mm, allowing it to abut against the connector. This enables the connector to press the second support section 112c, causing it to form a teardrop-shaped outward bend. This also prevents excessive thickness of the second support section 112c from interfering with the rotating shaft mechanism and affecting the assembly of the electronic device. Specific values ​​for the thickness L3 of the second support section 112c can be 0.6mm, 0.7mm, 0.8mm, etc.

[0108] Please also refer to Figure 17, which shows the simulated deformation result of the bamboo book in Figure 16. As can be seen from Figure 17, the bamboo book 112 with different thicknesses provided in this application embodiment tends to automatically form a teardrop shape when the electronic device is in a folded state, thus meeting the usage requirements.

[0109] In one specific embodiment, as shown in FIG18 (a partially enlarged view of part I in FIG11), the rotating shaft mechanism 123 may include a base 123a, a swing arm 123b, and a connector 123c. The swing arm 123b is symmetrically arranged along the base 123a, and one end of the swing arm 123b is rotatably connected to the base 123a. The connector 123c is disposed on both sides of the base 123a along the width direction Y of the electronic device, and there is a gap between the connector 123c and the base 123a. The other end of the swing arm 123b is connected to the base 123a. As described in the above embodiments, the bamboo book 112 may include, but is not limited to, the two specific configuration forms shown in FIG9 and FIG16. When the bamboo book 112 is configured as shown in Figure 16, the bamboo book 112 has two second support sections 112c symmetrically arranged along the width direction Y of the electronic device in the flattened state. The two second support sections 112c are located on both sides of the first support section 112b, and the first support section 112b and the second support sections 112c are connected by a body section 112a. The bamboo book 112 also has two body sections 112a symmetrically arranged along the width direction Y of the electronic device in the flattened state, and the two body sections 112a are respectively connected to the ends of the two second support sections 112c that are far apart from each other.

[0110] In this embodiment, when the electronic device is in a flattened state, along the thickness direction Z of the electronic device, the projections of the two second support segments 112c respectively cover the connectors 123c located on both sides of the base 123a, and the projection of the first support segment 112b covers the base 123a.

[0111] When the bamboo book 112 is configured as shown in Figure 9, in the flattened state, the first support segment 112b can be directly connected to the side of the two second support segments 112c that are close to each other.

[0112] In this embodiment, when the bamboo book 112 is flattened, the first support segment 112b is directly connected to the two second support segments 112c on their adjacent sides, so that the two second support segments 112c are both first support segments 112a with the same thickness, which facilitates processing and improves the flatness of the foldable part 111c. When the electronic device is flattened, along the thickness direction Z of the electronic device, the projection of the first support segment 112b covers the gap between the connectors 123c on both sides of the base 123a (i.e., within the area of ​​the dotted line in Figure 11), and the projections of the two second support segments 112c respectively cover the connectors 123c on both sides of the base 123a.

[0113] In one specific embodiment, as shown in FIG19, FIG19 is a schematic diagram of the screen assembly 11 provided in this application in a specific embodiment. The projection of the body segment 112a along the thickness direction Z of the electronic device corresponds to the first display portion 111a and the second display portion 111b. The projections of the first support segment 112b and the second support segment 112c along the thickness direction Z of the electronic device correspond to the foldable portion 111c.

[0114] In this embodiment, the projection of the body segment 112a along the thickness direction Z of the electronic device corresponds to the first display portion 111a and the second display portion 111b. This increases the connection area between the body segment 112a and the first display portion 111a and the second display portion 111b, thereby improving the connection reliability between the screen module 111 and the bamboo book 112. Furthermore, the projections of the first support segment 112b and the second support segment 112c along the thickness direction Z of the electronic device correspond to the foldable portion 111c. This allows the foldable portion 111c to be constrained into a teardrop shape under the combined action of the first support segment 112b and the second support segment 112c, thereby reducing the crease depth of the foldable portion 111c after prolonged use.

[0115] In one specific embodiment, at least one through hole may be provided on the first support section 112b, and / or at least one blind hole may be provided on the second support section 112c.

[0116] In this embodiment, the through-hole structure provided on the first support segment 112b can further optimize the stiffness distribution of the first support segment 112b, so that when the bamboo book 112 is bent, the first support segment 112b can automatically form a teardrop-shaped inward bend. Simultaneously, the blind hole structure provided on the second support segment 112c can further optimize the stiffness distribution of the second support segment 112c, so that the second support segment 112c can form a teardrop-shaped outward bend under the pressure of the connector 123c, and the inclination angle of the outward bend can be controlled to meet usage requirements.

[0117] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
