Description

Technical Field

[0001] This application belongs to the field of electronics, and in particular relates to an electronic device. Background Technology

[0002] With the development of display technology, consumers' demands for electronic device displays are becoming increasingly diverse and personalized. Foldable electronic devices combine portability with a large, high-definition screen, catering to today's consumers' pursuit of portability and functionality. However, the display may produce rattles during the folding process, reducing the user experience. Summary of the Invention

[0003] This application provides an electronic device that can at least solve the problem of abnormal noises in electronic devices.

[0004] This application provides an electronic device including a hinge assembly, a support member, and a shielding member. The hinge assembly includes a first plate and a second plate that are rotatable relative to each other, with the first plate and the second plate spaced apart. The support member covers the gap between the first plate and the second plate, with a first side of the support member fixedly connected to the first plate and a second side of the support member movably overlapping the second plate. The hinge assembly is provided with a lubricant. The shielding member is disposed between the support member and the hinge assembly, and covers at least a portion of the gap between the first plate and the second plate.

[0005] The electronic device provided in this application embodiment includes a shielding member between the support member and the hinge assembly. This increases the height difference between the support member and the hinge assembly, preventing the lubricating oil in the hinge assembly from contacting the support member during rotation. This effectively reduces the abnormal noise caused by the lubricating oil adhering to or separating from the support member, improving the user experience. Furthermore, the shielding member between the support member and the hinge assembly provides support for the curved portion of the screen, ensuring the screen maintains a suitable curvature during folding to keep it flat. Compared to direct contact between the hinge assembly and the support member, this reduces the abruptness of the hinge assembly directly contacting the support member, effectively enhancing the perceived value of the electronic device.

[0022] To address the existing technical problems, embodiments of this application provide an electronic device. For a better understanding of this application, the following description is provided in conjunction with... Figures 1 to 5 The electronic devices described in the embodiments of this application will be described in detail.

[0023] The electronic device provided in the embodiments of this application will be described below first.

[0024] Please see Figure 1 and Figure 2 , Figure 1 This is a partial structural diagram of an electronic device in the unfolded state according to an embodiment of this application; Figure 2 This is a schematic diagram of the structure of the shielding component of the electronic device according to an embodiment of this application.

[0025] like Figure 1 and 2 As shown, this application discloses an electronic device 100, including a hinge assembly 10, a support member 20, and a blocking member 30. The hinge assembly 10 includes a first plate 11 and a second plate 12 that are rotatable relative to each other, with the first plate 11 and the second plate 12 spaced apart. The support member 20 covers the gap between the first plate 11 and the second plate 12. A first side 21 of the support member 20 is fixedly connected to the first plate 11, and a second side 22 of the support member 20 is movably overlapped with the second plate 12. The hinge assembly 10 is provided with a lubricant. The blocking member 30 is disposed between the support member 20 and the hinge assembly 10, and covers at least a portion of the gap between the first plate 11 and the second plate 12.

[0026] The hinge assembly 10 enables the electronic device 100 to fold, allowing it to move relative to other parts of the device and switch between folded and unfolded states. Since the hinge assembly 10 is a moving part, it requires lubricant to ensure smooth movement of its components, such as the swing arm or gear, during rotation. However, during rotation, the lubricant on the hinge assembly 10 inevitably comes into contact with and adheres to the support member 20. When the lubricant separates from the support member 20, a rattling noise occurs.

[0027] Optionally, the lubricant is lubricating oil.

[0028] The support member 20, used to support the screen body, is located on one side of the back of the screen body, i.e., the non-display surface. The support member 20 effectively supports the screen body, improving its structural strength and impact resistance. Furthermore, the support member 20 is positioned between the screen body and the hinge assembly 10, and at least covers the gap in the hinge assembly 10, reducing wear on the bent parts of the screen body caused by the hinge assembly 10. This reduces the risk of damage during bending, thereby minimizing defects such as color patches, color dots, and bright lines on the screen, improving product quality and user experience, and reducing after-sales costs.

[0029] Furthermore, since the first side 21 of the support member 20 is fixed to the hinge assembly 10, that is, the first side 21 is fixedly connected to the first plate 11, and the second side 22 is separable from the hinge assembly 10, that is, the second side 22 is movably overlapped with the second plate 12, during the rotation of the hinge assembly 10, that is, during the bending and folding of the screen, the second side 22 of the support member 20 will move freely between the screen and the hinge assembly 10, without causing any pulling on the screen and resulting in damage to the screen.

[0030] Optionally, the support member 20 may be made of bendable steel or copper sheets.

[0031] A blocking member 30 is disposed between the support member 20 and the hinge assembly 10, creating a height difference between them. This reduces the contact between the lubricant and the support member 20, thereby reducing the noise that may occur when the lubricant separates from the support member 20. The blocking member 30 can be connected to the support member 20, fitting against a surface of the hinge assembly 10 facing the support member 20; or it can be connected to the hinge assembly 10, ensuring its stable placement between the support member 20 and the hinge assembly 10. Furthermore, the blocking member 30 can bend with the support member 20, or it can rotate with the hinge assembly 10.

[0032] When the electronic device 100 is folded, the screen sags under gravity, and this sag is difficult to correct itself. The hinge assembly 10 abuts against the support member 20 to mitigate this sag. However, the hinge assembly 10 is typically made of a rigid material, which can cause the screen to appear abrupt. Therefore, a shielding member 30 is placed between the support member 20 and the hinge assembly 10. This shielding member 30 can be made of a highly tolerant material. When the electronic device 100 is unfolded, the shielding member 30 can more gently support the sag, allowing for a smooth transition and maintaining a suitable curvature to keep the screen flat. Furthermore, appropriately increasing the thickness of the shielding member 30, i.e., widening the gap between the support member 20 and the hinge assembly 10, and filling this gap, results in better screen flatness and a more pleasant user experience.

[0033] Optionally, the shielding element 30 has a shielding layer or shielding pad with a certain degree of elasticity or toughness.

[0034] In the electronic device 100 provided in this application embodiment, a shielding member 30 is provided between the support member 20 and the hinge assembly 10 to increase the height difference between the support member 20 and the hinge assembly 10. This prevents the lubricating oil in the hinge assembly 10 from contacting the support member 20 during rotation, effectively reducing the abnormal noise caused by the lubricating oil adhering to or separating from the support member 20, and improving the user experience. Furthermore, the shielding member 30 between the support member 20 and the hinge assembly 10 provides support for the curved portion of the screen and ensures that the screen maintains a suitable curvature during folding to maintain its flatness. Compared to direct contact between the hinge assembly 10 and the support member 20, this reduces the abruptness of the hinge assembly 10 directly contacting the support member 20, thereby effectively enhancing the perceived value of the electronic device 100.

[0035] In some alternative embodiments, such as Figure 1 and Figure 2 As shown, the shielding member 30 is connected to the second side 22, and the shielding member 30 extends from the second side 22 toward the gap and into the gap.

[0036] In this embodiment, the support member 20 includes a first side 21 and a second side 22. A first plate 11 and a second plate 12 are spaced apart. The first side 21 is fixedly connected to the first plate 11. Specifically, an adhesive layer may be attached to the side of the first side 21 facing the first plate 11, and the first side 21 and the first plate 11 are fixed together by the adhesive layer. A blocking member 30 is connected to the second side 22 and extends from the second side 22 into the gap. During the folding process of the support member 20 with the screen, the blocking member 30 can move relative to the second plate 12 with the second side 22 of the support member 20.

[0037] In some embodiments of this application, the shielding member 30 completely covers the gap between the first plate 11 and the second plate 12. This can be understood as the shielding member 30 extending from the second side 22 toward the gap and covering the entire gap. With this configuration, the shielding member 30 can prevent the second support from contacting the lubricant, thereby reducing abnormal noise when the lubricant separates from the support member 20.

[0038] In some other embodiments of this application, the shielding member 30 partially covers the gap between the first plate 11 and the second plate 12. This can be understood as the shielding member 30 extending from the second side 22 toward the gap and covering part of the gap. This arrangement makes the support member 20 and the hinge assembly 10 spaced apart, reducing the probability of the support member 20 coming into contact with the lubricant. It can also reduce the abnormal noise when the lubricant separates from the support member 20.

[0039] In this embodiment, there are multiple blocking members 30, which are spaced apart on the second side 22. The blocking members 30 can be circular, rectangular, trapezoidal, triangular, or other structures. Optionally, the multiple blocking members 30 are arranged equidistantly on the second side 22. More preferably, the multiple blocking members 30 are arranged in rows or columns on the second side 22.

[0040] In this application embodiment, there are various ways to connect the shielding member 30 and the second side 22, such as: bonding, snap-fitting, welding or riveting, etc., and this application is not limited to these.

[0041] Optionally, the shield 30 is detachably connected to the second side 22 to facilitate replacement of any damaged shield 30.

[0042] In this embodiment, a gap needs to be reserved between the support member 20 and the hinge assembly 10 for the blocking member 30, so that a step difference, i.e., a height difference, is formed between the support member 20 and the hinge assembly 10, reducing the probability of the lubricant on the hinge assembly 10 contacting the support member 20. Moreover, the blocking member 30 forms at least partial obstruction in the gap between the first plate 11 and the second plate 12, further reducing the probability of the lubricant contacting the support member 20. In addition, the blocking member 30 is connected to the second side 22 of the support member 20, so that the relative position of the blocking member 30 and the support member 20 is relatively fixed. To a certain extent, the blocking member 30 stably supports the support member 20, and the support member 20 can drive the blocking member 30 to move synchronously, ensuring the stability of the movement of the blocking member 30.

[0043] See also Figure 3 , Figure 3 This is a partial cross-sectional structural diagram of the electronic device 100 according to an embodiment of this application.

[0044] In some alternative embodiments, such as Figures 1 to 3 As shown, the hinge assembly 10 includes a first swing arm 13 and a second swing arm 14, both of which are rotatable. The blocking member 30 has multiple clearance slots 31 for accommodating the first swing arm 13 and the second swing arm 14.

[0045] In this embodiment, the hinge assembly 10 includes a base, which is the fundamental component of the hinge assembly 10. The base provides a mounting foundation for other components of the hinge assembly 10, allowing other components of the hinge assembly 10 to be mounted directly or indirectly on the base, such as the first swing arm 13 or the second swing arm 14. Optionally, the base is a thin plate to reduce space occupation. The first swing arm 13 and the second swing arm 14 are movable components in the hinge assembly 10. The first swing arm 13 and the second swing arm 14 are respectively connected to the base, with the first swing arm 13 movably connected to the base and the second swing arm 14 movably connected to the base.

[0046] For example, the first swing arm 13 and the second swing arm 14 can be symmetrically arranged on both sides of the base. That is, the two sides of the base are respectively provided with the first swing arm 13, and the two first swing arms 13 are arranged opposite each other. Similarly, the two sides of the base are respectively provided with the second swing arm 14, and the two second swing arms 14 are arranged opposite each other. The relative rotation of the two first swing arms 13 and the relative rotation of the two second swing arms 14 realizes the folding state of the hinge assembly 10. This symmetrical arrangement can make the weight of the hinge assembly 10 more balanced and avoid the occurrence of uneven weight distribution.

[0047] In this embodiment, during the rotation of the hinge assembly 10, the first swing arm 13 and the second swing arm 14 move. The lubricant on the surface of the moving first swing arm 13 and / or the second swing arm 14 comes into contact with the support member 20. Therefore, a blocking member 30 is provided between the hinge assembly 10 and the support member 20 to prevent the support member 20 from contacting the lubricant. However, after the blocking member 30 is provided, the moving first swing arm 13 and / or the second swing arm 14 will rub against the blocking member 30. Moreover, when the lubricant on the first swing arm 13 and / or the second swing arm 14 separates from the blocking member 30, an abnormal noise will also be generated. This abnormal noise is less loud than the noise when the lubricant separates from the support member 20. In addition, part of the blocking member 30 may be caught in the hinge assembly 10, causing the hinge assembly 10 to jam. Therefore, the shield 30 is provided with a relief groove 31 to reduce the contact between the first swing arm 13 and / or the second swing arm 14 and the shield 30, reduce the occurrence of friction, and further reduce the problem of jamming of the hinge assembly 10.

[0048] In some embodiments of this application, the blocking member 30 has multiple clearance slots 31, wherein one clearance slot 31 can accommodate multiple first swing arms 13 or multiple second swing arms 14, or each clearance slot 31 accommodates each first swing arm 13 or each second swing arm 14. This arrangement reduces the span of the clearance slots 31 and improves the connection stability between the blocking member 30 and the support member 20.

[0049] Optionally, the clearance slot 31 can be a blind slot or a through slot.

[0050] In the embodiments of this application, such as Figure 2 and Figure 3 As shown, the hinge assembly 10 includes a plurality of first swing arms 13 and a plurality of second swing arms 14, and a plurality of clearance slots 31 include a plurality of first sub-slots and a plurality of second sub-slots. Each first sub-slot is correspondingly arranged with each first swing arm 13, and each second sub-slot is correspondingly arranged with each second swing arm 14. At least two first swing arms 13 are symmetrically arranged on both sides of the base, and at least two second swing arms 14 are symmetrically arranged on both sides of the base.

[0051] Exemplarily, the hinge assembly 10 includes six first swing arms 13. Optionally, all six first swing arms 13 are virtual swing arms, wherein three virtual swing arms are disposed on a first side end of the base, with the three virtual swing arms on the first side end spaced apart, and the other three virtual swing arms are disposed on a second side end of the base, corresponding one-to-one with the three virtual swing arms on the first side end. The hinge assembly 10 includes six second swing arms 14. Optionally, all six second swing arms 14 are synchronous swing arms, wherein three synchronous swing arms are disposed on a first side end of the base, with the three synchronous swing arms on the first side end spaced apart, and the other three synchronous swing arms are disposed on a second side end of the base, corresponding one-to-one with the three synchronous swing arms on the first side end. Furthermore, the first swing arms 13 cooperate with the second swing arms 14 on the same side to achieve synchronous movement of the first swing arms 13 and the second swing arms 14.

[0052] In this embodiment, the clearance groove 31 includes multiple first sub-grooves and multiple second sub-grooves. The opening areas of the first sub-grooves and the second sub-grooves may be equal or unequal, and the opening sizes of the first sub-grooves and the second sub-grooves can be determined according to the specific circumstances of the first swing arm 13 and the second swing arm 14. Optionally, the opening shape of the clearance groove 31 is rectangular or circular.

[0053] In these optional embodiments, the shielding member 30 is provided with multiple clearance grooves 31. These clearance grooves 31 can avoid contact between the first swing arm 13 and the second swing arm 14, reducing the probability of contact between the first swing arm 13 and / or the second swing arm 14 and the shielding member 30. This reduces wear on the shielding member 30, increases its service life, and maintains the stability of the rotational movement of the hinge assembly 10. Furthermore, the shielding member 30 has multiple clearance grooves 31 evenly distributed, reducing the contact area between the shielding member 30 and the support member 20, thus effectively ensuring the display effect of the screen. It also reduces the risk of excessively large openings in some clearance grooves 31 on the shielding member 30, which could lead to poor connection stability between the shielding member 30 and the support member 20, and problems such as the shielding member 30 detaching or curling.

[0054] In some optional embodiments, the shielding member 30 has a plurality of through slots 32, which are spaced apart and are separate from and spaced apart from the clearance slots 31.

[0055] In this embodiment, the shielding member 30 has multiple through slots 32, which are spaced apart. The through slots 32 can be disposed between adjacent first sub-slots, or between adjacent second sub-slots, or between adjacent first and second sub-slots.

[0056] In these optional embodiments, the arrangement of multiple through slots 32 makes the slots opened on the shielding member 30 more uniform, that is, the through slots 32 and the clearance slots 31 on the shielding member 30 are evenly distributed. This can avoid the local slot openings being too large, which would result in poor connection stability between the shielding member 30 and the support member 20. During the folding process of the electronic device 100, the shielding member 30 is prone to falling off or curling. It can also ensure that the shielding member 30 and the support member 20 have a suitable connection area, thereby ensuring the display effect of the screen.

[0057] In some alternative embodiments, such as Figure 1 As shown, the electronic device 100 also includes a first protective layer 40, which is disposed between the shielding member 30 and the second plate 12 and is connected to the second plate 12. The second side 22 of the support member 20 and the shielding member 30 are slidably overlapped with the first protective layer 40.

[0058] In this embodiment of the application, the electronic device 100 includes a first protective layer 40, which is disposed between the shielding member 30 and the hinge assembly 10 and is connected to the hinge assembly 10. The first protective layer 40 may be disposed between the entire shielding member 30 and the second plate 12, or it may be disposed only at the movable part of the shielding member 30 and the second plate 12, which can reduce the cost of the first protective layer 40.

[0059] Optionally, the first protective layer 40 is selected from a hard anti-wear layer, a Teflon coating, or a coating formed by a lubricating material.

[0060] Alternatively, the first protective layer 40 is a Teflon coating. The Teflon coating can be used for lubrication and is wear-resistant, further reducing the friction between the shield 30 and the hinge assembly 10.

[0061] In these optional embodiments, the first protective layer 40 is disposed between the shielding member 30 and the second plate 12, and during the rotation of the hinge assembly 10, the second side 22 of the support member 20 and the shielding member 30 can slide and overlap with the first protective layer 40, reducing the situation where the shielding member 30 and the second plate 12 rub against each other and make abnormal noises, thereby improving the user experience.

[0062] Figure 4 This is a partial structural diagram of an electronic device 100 in an unfolded state according to another embodiment of this application; Figure 5 yes Figure 4 A partially enlarged view of the electronic device 100 shown.

[0063] In some alternative embodiments, such as Figure 4 and Figure 5As shown, the shielding member 30 includes a first shielding member 33 and a second shielding member 34. The first shielding member 33 is fixed to the first plate 11 and extends into the gap, and the second shielding member 34 is fixed to the second plate 12 and extends into the gap.

[0064] In this embodiment, the hinge assembly 10 includes a first plate 11 and a second plate 12 that can rotate relative to each other. The first plate 11 and the second plate 12 are structural components of the hinge assembly 10 used to support the screen. During the rotation of the hinge assembly 10, the first plate 11 and the second plate 12 can be driven by movable components (such as the first swing arm 13 and / or the second swing arm 14), and the first plate 11 and the second plate 12 can rotate relative to each other. The first plate 11 and the second plate 12 can also be symmetrically arranged on both sides of the base. This makes the weight of the hinge assembly 10 more balanced and avoids the occurrence of uneven weight distribution.

[0065] In this embodiment, the shielding member 30 includes a first shielding member 33 and a second shielding member 34. The first shielding member 33 and the second shielding member 34 can be an integral structure or separate structures. When separate, the first shielding member 33 and the second shielding member 34 can be connected together or spaced apart. The first shielding member 33 is fixed to the first plate 11 and extends into the gap, and the second shielding member 34 is fixed to the second plate 12 and extends into the gap.

[0066] For example, a portion of the first plate 11 is fixedly connected to the first side 21 of the support member 20, and the portion of the first plate 11 is glued and fixed to the first side 21 of the support member 20 by an adhesive layer. Another portion of the first plate 11 is fixedly connected to the first shielding member 33 and extends to the gap between the first plate 11 and the second plate 12.

[0067] In some embodiments of this application, the first blocking member 33 is fixed to the first plate 11 and extends into the gap, and the second blocking member 34 is fixed to the second plate 12 and extends into the gap. The first blocking member 33 and the second blocking member 34 are mated or overlapped so that the first blocking member 33 and the second blocking member 34 completely cover the gap between the first plate 11 and the second plate 12. With this configuration, the blocking member 30 can better block the lubricant and the support member 20 of the hinge assembly 10, reducing the probability of contact between the lubricant and the support member 20.

[0068] In other embodiments of this application, the first blocking member 33 is fixed to the first plate 11 and extends into the gap, and the second blocking member 34 is fixed to the second plate 12 and extends into the gap. The first blocking member 33 and the second blocking member 34 are spaced apart so that they partially cover the gap between the first plate 11 and the second plate 12. With this arrangement, a height difference exists between the hinge assembly 10 and the support member 20, which also reduces the probability of lubricant contacting the support member 20.

[0069] In this embodiment, there are various ways to connect the first shielding member 33 to the first plate 11, and the second shielding member 34 to the second plate 12, such as bonding, snap-fitting, welding, or riveting. Optionally, the first shielding member 33 is bonded to the first plate 11, and the second shielding member 34 is bonded to the second plate 12.

[0070] Optionally, the first shielding member 33 is detachably connected to the first plate 11, and the second shielding member 34 is detachably connected to the second plate 12. This facilitates the replacement of any damaged shielding member 30.

[0071] In this embodiment, the first blocking member 33 is fixed to the first plate 11 and extends into the gap, and the second blocking member 34 is fixed to the second plate 12 and extends into the gap. The first swing arm 13 and the second swing arm 14 may pull the first blocking member 33 and / or the second blocking member 34. Therefore, the blocking member 30 needs to have a certain degree of extensibility to reduce the risk of tearing when pulled.

[0072] Optionally, the shielding element 30 is made of foam with a certain degree of elasticity.

[0073] In this embodiment, the blocking member 30 includes a first blocking member 33 and a second blocking member 34. The first blocking member 33 is fixed to the first plate 11, and the second blocking member 34 is fixed to the second plate 12. Neither the first blocking member 33 nor the second blocking member 34 has an avoidance groove 31. This is mainly because the first blocking member 33 is fixed to the first plate 11 and the second blocking member 34 is fixed to the second plate 12, allowing the first blocking member 33 and the second blocking member 34 to move synchronously with the first plate 11 and the second plate 12.

[0074] Therefore, compared to the situation where the shielding member 30 is fixed to the support member 20 and subjected to collision or compression forces from the hinge assembly 10, the shielding member 30 is fixed to the hinge assembly 10, and the movement of the hinge assembly 10 is smaller relative to the movement of the shielding member 30, resulting in a smaller force on the shielding member 30. Furthermore, since the shielding member 30 moves synchronously with the first plate 11 and the second plate 12, it will be subjected to pulling forces. If the clearance groove 31 is provided, the shielding member 30 may be damaged due to this pulling.

[0075] In these alternative embodiments, the shielding member 30 is connected to the first plate 11 and the second plate 12, so that the relative position of the shielding member 30 and the hinge assembly 10 is relatively fixed. To a certain extent, the shielding member 30 can stably block the lubricant on the hinge assembly 10 from contacting the support member 20, and form a height difference between the support member 20 and the hinge assembly 10.

[0076] In some alternative embodiments, such as Figure 4 and Figure 5 As shown, the electronic device 100 also includes a second protective layer 50, which is disposed between the second side 22 and the second shielding member 34, and the second side 22 of the support member 20 is slidably overlapped with the second protective layer 50.

[0077] In this embodiment, the electronic device 100 further includes a second protective layer 50. The second protective layer 50 is disposed on the second side 22 and the second shielding member 34, and the second protective layer 50 is connected to the shielding member 34. During the rotation of the hinge assembly 10, the second side 22 of the support member 20 slides relative to the second protective layer 50, and the second side 22 overlaps with the second protective layer 50.

[0078] Optionally, the second protective layer 50 is selected from a hard anti-wear layer, a Teflon coating, or a coating formed of a lubricating material. The second protective layer 50 is bonded to the shielding member 30.

[0079] Alternatively, the second protective layer 50 is a Teflon coating. The Teflon coating can be used for lubrication and is wear-resistant, further reducing the friction between the shield 30 and the hinge assembly 10.

[0080] In these optional embodiments, the second protective layer 50 is disposed between the second side 22 and the second shield 34, and during the rotation of the hinge assembly 10, the second protective layer 50 and the second side 22 of the support member 20 can slide relative to each other, thereby avoiding friction between the shield 30 and the second side 22 of the support member 20, effectively reducing friction damage to the shield 30 and extending the service life of the shield 30.

[0081] In some alternative embodiments, the shielding member 30 has a first side and a second side and a third side respectively connected to opposite ends of the first side, the first side extending into the gap. The second protective layer 50 has a first sidewall and a second sidewall and a third sidewall respectively connected to opposite ends of the first sidewall, the first sidewall being located on the second plate 12, the second sidewall being aligned with the second side, and the third sidewall being aligned with the third side.

[0082] In this embodiment, the shielding member 30 has a first side, a second side, and a third side. The first side extends into the gap, and the second and third sides are located at both ends of the first side. The second and third sides are at least partially located on the second plate 12. The second protective layer 50 has a first sidewall, a second sidewall, and a third sidewall. The first sidewall is located on the second plate 12, and the second and third sidewalls are located at both ends of the first side. The second sidewall is aligned with the second side, and the third sidewall is aligned with the third side. This can be understood as the shielding member 30 and the second protective layer 50 having the same or equal length and width on the second plate 12.

[0083] In these optional embodiments, the second protective layer 50 is stably positioned on the shielding member 30 after the shielding member 30 and the second protective layer 50 are superimposed, without forming a step difference. During the sliding process between the second protective layer 50 and the support member 20, the abnormal noise generated by the sliding between the second protective layer 50 and the support member 20 is low.

[0084] In some optional embodiments, the hinge assembly 10 further includes a support block 15 disposed between the first plate 11 and the second plate 12, the support block 15 and the support member 20 being spaced apart, the gap being located between the support block 15 and the support member 20, and the blocking member 30 extending between the support block 15 and the support member 20.

[0085] In these alternative embodiments, the support block 15 is part of the hinge assembly 10, and the support block 15 and the support member 20 are spaced apart to form a gap, and the shielding member 30 extends into the gap, so that a step difference, i.e. a height difference, is formed between the support member 20 and the support block 15, thereby reducing the probability of the support block 15 and the support member 20 coming into contact.

[0086] In some alternative embodiments, the electronic device 100 further includes a screen disposed on the side of the support 20 opposite to the shield 30.

[0087] In this embodiment, the hinge assembly 10 enables the screen to move relative to each other, allowing the screen to switch between a folded state and an unfolded state. The hinge area between the screen and the hinge assembly 10 is a flexible screen; under stress, the screen can bend in the hinge area, causing the screens to face each other and eventually fit together or move away from each other.

[0088] For example, the screen includes a first part and a second part that rotate relative to each other. The first plate 11 and the second plate 12 are spaced apart. When the electronic device 100 is in a folded state, the first part and the second part are stacked and arranged relative to each other. Of course, the first part and the second part can be parallel to each other, or there can be a relatively small acute angle between the first part and the second part. The electronic device 100 in the folded state is easy to carry.

[0089] For example, when the electronic device 100 is in the unfolded state, the display surface of the screen is a flat plane. However, considering factors such as manufacturing precision and the inherent properties of the screen itself, the display surface of the screen in the unfolded state may not be an absolutely flat structure; some locations on the display surface may exhibit slight bending or deformation. In such cases, the screen (or electronic device 100) can be considered to be in the unfolded state. The unfolded electronic device 100 serves the purpose of displaying a larger area. As described above, during the use of the electronic device 100, the screen will deform with the relative movement of the hinge assembly 10 to present different states.

[0090] In some alternative embodiments, the shielding element 30 is a foam layer, a rubber layer, or an elastic adhesive layer.

[0091] Optionally, the shielding element 30 is a foam layer.

[0092] In these alternative embodiments, the foam is a soft, tolerant material disposed between the support member 20 and the hinge assembly 10, which can more gently support the support member 20 and reduce the problem of dents appearing when the hinge assembly 10 abuts against the support member 20.

[0093] In this embodiment of the application, the electronic device 100 may be a mobile phone, tablet computer, laptop computer, handheld computer, vehicle electronic device 100, wearable device, ultra-mobile personal computer (UMPC), netbook, or personal digital assistant (PDA), etc.

[0094] Other configurations and operations of the electronic devices according to embodiments of this application are known to those skilled in the art and will not be described in detail here.
