Description

Technical Field

[0001] This invention relates to the technical field of foldable electronic device structures, and more specifically to a foldable electronic device and its folding components. Background Technology

[0002] Currently, foldable phones generally consist of a flexible screen, a hinge, and a casing. The flexible screen is divided into a bending area and a non-bending area based on its movement. The bending area corresponds to the hinge region, which is in motion during the bending process. Conventional flexible displays use a complex and costly bonding assembly. The connectors of the bonding assembly occupy a significant amount of space in the hinge's decorative parts, reducing the supporting area of ​​the hinge and making it prone to deformation during corner drops, potentially causing the rotation mechanism to jam. Furthermore, due to limitations in adhesive bonding and the fixing structure, the bonding part of the bonding assembly is nearly 1mm higher than the display screen. A frontal drop places greater stress on the bonding assembly, making it susceptible to deformation and damage to the screen. Summary of the Invention

[0003] A first aspect of this application provides a folding assembly for a foldable electronic device, the folding assembly comprising:

[0004] pivot assembly;

[0005] A hinge decoration is provided around the hinge assembly and is fixedly connected to the hinge assembly. When the device is in a folded state, the hinge decoration is exposed on the side of the device. The hinge decoration is used to protect the hinge assembly.

[0006] The pressing component is made of a flexible material; its opposite ends are respectively used to slidably connect with the housing of the electronic device in the length extension direction of the pressing component; the pressing component is used to press and position the bending area of ​​the flexible display screen.

[0007] A connector, one end of which is integrally formed with the middle part of the press-fit component, and the other end of which is connected to the rotating shaft decorative component, thereby realizing the connection between the press-fit component and the rotating shaft decorative component.

[0008] Secondly, embodiments of this application provide a foldable electronic device, the electronic device including a housing, a flexible display screen, and a folding assembly as described in any of the above embodiments; the housing includes a first housing and a second housing, the first housing and the second housing being respectively connected to the pivot assembly, and the first housing and the second housing being rotatable relative to the pivot assembly;

[0009] The flexible display screen is connected to the housing and can be folded or unfolded as the housing rotates relative to it.

[0010] The folding assembly for foldable electronic devices provided in this application embodiment features a simple connector and integrates the pressing component and connector into a single unit, resulting in a simple structure and cost savings. The overall height of the pressing component and connector is reduced compared to conventional designs, while also minimizing space usage. This allows for a more robust and reliable hinge decoration, thus better protecting the hinge assembly and ensuring that the unfolding and folding functions of the foldable electronic device are not affected. Furthermore, when the flexible display is unfolded, the pressing component is lower in height relative to the flexible display compared to the housing decoration (first and second pressure plates). When the foldable electronic device is dropped or impacted, the housing decoration (first and second pressure plates) bears the force first, thereby enabling the pressing component to better protect the flexible display of the foldable electronic device.

[0030] Please refer to the following: Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the unfolded state of an embodiment of the foldable electronic device of this application. Figure 2 yes Figure 1 The embodiment shows a schematic diagram of the folded state structure of the electronic device. It should be noted that the electronic device in this application may include mobile phones, tablets, laptops, wearable devices, and other electronic devices with foldable flexible displays. The electronic device 10 includes, but is not limited to, the following structures: a housing 100, a flexible display 200, and a folding assembly 300. It should be noted that the terms "comprising" and "having," and any variations thereof, in the embodiments of this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or components inherent to these processes, methods, products, or devices.

[0031] For details, please refer to the following: Figure 3 , Figure 3 yes Figure 1 A partial structural breakdown diagram of the electronic device shows that the flexible display screen 200 is connected to the housing 100 and can fold as the housing 100 rotates relative to it. Figure 2 (in medium condition) or flattened ( Figure 1In the middle state), the pressing component 310 is disposed on opposite sides of the bending area of ​​the flexible display screen 200, and is used to press and position the bending area of ​​the flexible display screen 200 from the side position of the flexible display screen 200.

[0032] Alternatively, please continue reading Figure 3 The housing 100 includes a first housing 110 and a second housing 120; the first housing 110 and the second housing 120 are respectively connected to the rotating shaft assembly 340, and the first housing 110 and the second housing 120 can rotate relative to the rotating shaft assembly 340; the detailed structure of the rotating shaft assembly is within the understanding of those skilled in the art, and will not be described in detail here.

[0033] Optionally, the first housing 110 further includes a first support plate 111 and a first pressure plate 112; the first support plate 111 is rotatably connected to the rotating shaft assembly 340; the second housing 120 includes a second support plate 121 and a second pressure plate 122; the second support plate 121 is rotatably connected to the rotating shaft assembly 340; the flexible display screen 200 is disposed on the same side surface of the first support plate 111 and the second support plate 121, and the first pressure plate 112 and the second pressure plate 122 press the flexible display screen 200 from the edges of the first support plate 111 and the second support plate 121 respectively.

[0034] Please see Figure 4 , Figure 4 This is a schematic diagram of a structural embodiment of the integrated pressing component and connector of this application. Optionally, the folding assembly 300 includes a pressing component 310 and a connector 320. The pressing component 310 is made of a flexible material, specifically rubber. The pressing component 310 is bendable and has a certain degree of resilience. The opposite ends of the pressing component 310 are respectively used for slidable connection with the housing 100 of the electronic device in the length extension direction of the pressing component 310 (X direction in the figure). The pressing component 310 is used for pressing and positioning the bending area of ​​the flexible display screen. For details, please refer to... Figure 5 , Figure 5 yes Figure 1The enlarged structural diagram at point A shows that the two ends of the pressing member 310 are respectively inserted into the gap 101 between the first pressing plate 112 and the flexible display screen 200 and the gap 102 between the second pressing plate 122 and the flexible display screen 200. The first pressing plate 112 and the second pressing plate 122 restrict the Z-direction freedom of the end position of the pressing member 310, preventing the pressing member 310 from tilting up in the Z-direction or being clipped by the user. It should be noted that the terms "first," "second," and "third" in the embodiments of this application are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features.

In the description of this invention, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0035] Please refer to the following: Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 , Figure 6 This is an enlarged schematic diagram of a portion of the folding assembly excluding the hinge assembly. Figure 7 yes Figure 1 A partial sectional view of the hinge decoration, pressing part, and connecting part at point B-B; Optionally, the folding assembly 300 includes a hinge assembly 340, a hinge decoration 330, a pressing part 310, and a connecting part 320; the hinge decoration 330 surrounds the hinge assembly 340 and is fixedly connected to the hinge assembly 340. When the equipment is in a folded state, the hinge decoration 330 is exposed on the side of the equipment, and the hinge decoration 330 is used to protect the hinge assembly 340; one end of the connecting part 320 is integrally formed with the middle part of the pressing part 310, and the other end is connected to the hinge decoration 330, thereby realizing the connection between the pressing part 310 and the hinge decoration 330.

[0036] Please continue reading. Figure 4 The press-fit part 310 and the connector 320 are integrally formed. The connector 320 has a simple structure, which reduces the overall height of the press-fit part 310 and the connector 320. Figure 4 The height is reduced by 0.4~0.5mm compared to the conventional height (Z-direction). Optionally, the height can be reduced by 0.43mm, 0.45mm, or 0.48mm. The reduction in overall height and simplification of structure not only saves costs but also does not take up too much space. The hinge decoration 330 can be made more robust and reliable, thereby better protecting the hinge assembly 340 and ensuring that the unfolding and folding functions of the foldable electronic device are not affected.

[0037] Because the pressing component 310 is made of flexible material, it can be bent as the shell folds. Since the middle part of the pressing component 310 is connected to the pivot decorative component 330 through the connector 320, and the pivot decorative component 330 surrounds the pivot assembly 340, the two ends of the pressing component 310 can slide relative to the shell 100, thereby realizing the pressing and positioning of the flexible display screen 200 in the bending area and the waterproof and dustproof sealing of the gap between the flexible display screen 200 and the pivot assembly 340.

[0038] Please refer to the following: Figure 8 , Figure 8 This is a schematic diagram of the connector structure; optionally, the connector 320 includes a first connecting end 321, a second connecting end 322 and a body part 323 with an integral structure. The first connecting end 321 and the second connecting end 322 are respectively disposed at both ends of the body part 323. The first connecting end 321 is inserted into the pressing part 310 and integrally formed with the pressing part. The second connecting end 322 is connected to the rotating shaft decorative part 330.

[0039] Optionally, the connector 320 can be an elastic sheet structure. Optionally, the body portion 323 of the connector 320 can be provided with a corner 323a, which is used to mitigate the impact force between the pressing member 310 and the rotating shaft decorative member 330. Figure 5 (Impact force in the Y direction) When electronic devices are dropped or impacted, this prevents one of the pressing part 310 or the hinge decoration part 330 from being subjected to force that affects the other, thus mitigating the impact between the two.

[0040] Optionally, the connector 320 can be made of any one or a combination of metals, plastics, fiber materials, and composite materials. Metals such as steel, aluminum, and copper have high wear resistance and high temperature resistance, and can function under complex working conditions. Plastics such as polyethylene, polypropylene, and polystyrene have lightweight, insulating, corrosion-resistant, and cold-resistant properties, and are especially suitable for working under low loads. Fiber materials such as carbon fiber boards and carbon crystal boards have good mechanical properties and corrosion resistance. Composite materials have excellent mechanical, physical, and chemical properties. For example, xylene composites have high strength and excellent flexibility, and are widely used in electronic products.

[0041] Alternatively, please continue reading Figure 4 The pressing component 310 includes a connecting portion 311 and a pressing portion 313. The connecting portion 311 and the pressing portion 313 are arranged perpendicularly and are integrally formed. When the flexible display screen is unfolded, the pressing portion 313 is parallel to the flexible display screen. The pressing portion 313 is used to press and position the bending area of ​​the flexible display screen. Optionally, please refer to [further details omitted]. Figure 6 and Figure 7A protrusion 3111 is provided in the middle of the side of the connecting part 311 away from the pressing part 313. The protrusion 3111 extends in the direction away from the pressing part 313. The protrusion 3111 is used to limit the cooperation between the pressing part 310 and the rotating shaft decorative part 330. The first connecting end 321 of the connecting part 320 is inserted into the connecting part 311 through the protrusion 3111. Optionally, lugs 3112 are provided at both ends of the side of the connecting part 311 away from the pressing part 313. The lugs 3112 are provided with through holes 3112a. The through holes 3112a are used to achieve a sliding connection with the housing in the length extension direction of the pressing part 310.

[0042] Alternatively, please continue reading Figure 6 and Figure 7 The two ends of the rotating shaft decorative part 330 that mate with the pressing part 310 are provided with blind holes 331, and the extension direction of the blind holes 331 is opposite to that of the rotating shaft assembly 340. The two ends of the rotating shaft decorative part 330 that mate with the pressing part 310 are also provided with protrusions 332, which are located on the side of the rotating shaft decorative part 330 facing the blind holes 331. The second connecting end 322 of the connector 320 is bent, and the protrusions 332 hold the bent portion, thus achieving the connection between the rotating shaft decorative part 330 and the connector 320. Optionally, please continue reading. Figure 7 Please refer to the following: Figure 9 , Figure 9 yes Figure 6 A magnified view of a partial structure from another perspective in the embodiment; the aforementioned blind hole 331 can be a stepped blind hole 331a, the protrusion 3111 of the pressing member 310 and the second connecting end 322 of the connector 320 are inserted into the stepped blind hole 331a to realize the connection between the pressing member 310 and the rotating shaft decorative member 330; wherein the protrusion 3111 is inserted into the larger diameter part of the stepped blind hole 331a to realize the limiting and pre-fixing of the connection and cooperation between the pressing member 310 and the rotating shaft decorative member 330, strengthening the connection between the pressing member 310 and the rotating shaft decorative member 330, making the connection between the two less prone to loosening.

[0043] Optionally, please refer to the following as well. Figures 10a-10f , Figures 10a-10fThis is a schematic diagram of the protrusion of the hinge decorative part locking the second connecting end of the connector. Optionally, in some embodiments, the shape of the protrusion 332 can be a cylinder, cube, cuboid, or irregular shape. In other embodiments, the protrusion 332 can also be other shapes, as long as the protrusion 332 can lock the second connecting end 322 to achieve connection. No specific limitation is made here. Similarly, optionally, in some embodiments, the second connecting end 322 of the connector 320 can be U-shaped, V-shaped, or irregularly shaped. In other embodiments, the second connecting end 322 can also be other shapes, as long as the second connecting end 322 can lock the protrusion 332 to achieve connection. No specific limitation is made here. The protrusion 332 locking the connector 320 achieves the connection between the hinge decorative part 330 and the connector 320, allowing them to be connected without the need for additional structures or other connection methods. This connection method is simpler and saves costs.

[0044] Please continue reading. Figure 6 Optionally, a reinforcing member 312 is provided at the connection point between the pressed component 310 and the housing. The reinforcing member 312 is embedded at opposite ends of the pressed component 310, and is integrally formed with the pressed component 310. The material hardness of the reinforcing member 312 is greater than that of the pressed component 310, used to enhance the connection strength of the pressed component 310. Optionally, the reinforcing member 312 can be metal or rigid plastic, such as stainless steel or metal alloy.

[0045] In this embodiment, the connection process of the pressing component 310, the connecting component 320, and the reinforcing component 312 can be as follows: the soft rubber (pressing component 310) and the SUS (the first connecting end 321 of the reinforcing component 312 and the connecting component 320) are injection molded together. The soft rubber on both sides of the first connecting end 321 can be bent. After the first connecting end 321 is fixed to the pressing component 310, it ensures that the bending area of ​​the soft rubber can still be bent, and also ensures that the gap between the soft rubber and the metal pressing block is small, improving the appearance. Please refer to [link to previous text]. Figure 11 and Figure 12 , Figure 11 This is a partial cross-sectional view of the electronic device in its unfolded state. Figure 12 This is a partial structural cross-sectional view of the electronic device in its folded state; when the electronic device is folded ( Figure 12 When the flexible display 200 is in a certain state, it pushes the soft rubber (pressing part 310) to bend, and when the electronic device unfolds ( Figure 11 When fully unfolded, the soft adhesive adheres to the flexible display screen 200 due to its own rebound force, and then unfolds. When fully unfolded, the soft adhesive is pressed in the Z direction by the shell decorative parts (first pressure plate 112 and second pressure plate 122).

[0046] The connector 320 and the pressing part 310 are integrally formed. The simple structure of the connector 320 ensures that when the pressing part 310 is connected to the rotating shaft decorative part 330 and the flexible display screen is in the unfolded state, the height of the pressing part 310 relative to the flexible display screen is ( Figure 5 The height of the housing trim (first pressure plate 112 and second pressure plate 122) relative to the flexible display screen is (in the Z direction). Figure 5 The height is 0.05-0.1mm lower in the Z direction, optionally 0.06mm lower, optionally 0.08mm lower. When the foldable electronic device is dropped or impacted, the housing decoration (first pressure plate and second pressure plate) is stressed first, so that the pressing part 310 can better protect the flexible display of the foldable electronic device.

[0047] The folding assembly for foldable electronic devices provided in this application embodiment features a simple connector and integrates the pressing component and connector into a single unit, resulting in a simple structure and cost savings. The overall height of the pressing component and connector is reduced compared to conventional designs, while also minimizing space usage. This allows for a more robust and reliable hinge decoration, thus better protecting the hinge assembly and ensuring that the unfolding and folding functions of the foldable electronic device are not affected. Furthermore, when the flexible display is unfolded, the pressing component is lower in height relative to the flexible display compared to the housing decoration (first and second pressure plates). When the foldable electronic device is dropped or impacted, the housing decoration (first and second pressure plates) bears the force first, thereby enabling the pressing component to better protect the flexible display of the foldable electronic device.

[0048] Please refer to the following: Figure 13 and Figure 14 , Figure 13 This is a cross-sectional view of the electronic device in its unfolded state.

Other structural features of the electronic device are within the understanding of those skilled in the art and will not be listed or described in detail here.

[0051] The foldable electronic device provided in this application embodiment features a folding assembly with a simple connecting member, and the pressing member and connecting member are integrally molded, resulting in a simple structure and cost savings. The overall height of the pressing member and connecting member is reduced compared to conventional designs, while also not occupying much space. This allows for a more robust and reliable hinge decoration, better protecting the hinge assembly and ensuring the unfolding and folding functions of the foldable electronic device are not affected. Furthermore, when the flexible display is unfolded, the pressing member and the housing decoration (first and second pressure plates) are lower relative to the flexible display. When the foldable electronic device is dropped or impacted, the housing decoration (first and second pressure plates) bears the force first, thus allowing the pressing member to better protect the flexible display of the foldable electronic device.
