Description

Technical Field

[0001] This application relates to the field of electronic devices, and more particularly to an antistatic component and a foldable electronic device. Background Technology

[0002] Electrostatic discharge (ESD) poses a significant threat to electronic components, especially electrostatic sensitive devices (ESSD). With the development of electronic components in recent years, ESSD devices have become increasingly less tolerant to static electricity. Without proper protective measures, they are prone to failure due to ESD during use.

[0003] Foldable terminal devices using flexible displays often encounter issues. Because the screen shifts during unfolding and bending, it cannot fully adhere to the phone's frame or other structural components. Therefore, non-metallic outer shells are used to protect the edges of the flexible display. However, these non-metallic components generally have poor conductivity, allowing static electricity generated in the screen area to easily enter the device through the gap between the screen and the outer shell. Consequently, the bending area of ​​the FPC (Flexible Printed Circuit) in the flexible display is highly susceptible to ESD (Electrostatic Discharge) failure, leading to display failure. Therefore, designing an anti-static component that can promptly guide static electricity to ground and prevent damage to the flexible display has become a pressing problem. Summary of the Invention

[0004] This application provides an anti-static component and a foldable electronic device that can guide static electricity to ground in a timely manner to avoid damaging the flexible display screen.

[0005] In a first aspect, an antistatic component is provided, comprising: a middle frame, wherein a first receiving groove and a second receiving groove are disposed on the surface of the middle frame, the first receiving groove and the second receiving groove are connected, and the first receiving groove extends along a first direction; a first frame, the first frame including a first extension portion, the first extension portion being installed in the first receiving groove, and a first conductive structure being disposed on the side surface of the first extension portion near the second receiving groove; and a spring piece, the spring piece being installed in the second receiving groove, the spring piece including a pressing portion and an elastic portion, the pressing portion being disposed at the connection between the first receiving groove and the second receiving groove, and the spring point of the pressing portion contacting the first conductive structure; when the first frame piece is installed on the middle frame, the elastic portion is subjected to the force of the pressing portion to provide a reverse elastic force in a second direction, the first direction being perpendicular to the second direction.

[0006] In this embodiment, the static electricity is guided from the spring contact to the middle frame by the spring contact, achieving timely grounding and preventing damage to the flexible display screen. This also improves the stability of the spring contact connection. Furthermore, the spring contact with the first conductive structure on the first extension on the side of the middle frame avoids the connection failure problem caused by the spring contact contacting the first frame on the top surface of the middle frame, thus increasing the service life and stability of the first frame.

[0007] Optionally, the first conductive structure can be disposed on the part of the first frame away from the antenna to avoid affecting the use of the antenna. This embodiment of the application does not specifically limit this. For example, when the first conductive structure is conductive silver paste, the conductive silver paste is coated in a ring along the side of the first frame near the first receiving groove. The coating width is set to avoid the antenna area. The pressing part of the spring contact is in contact with the part coated with conductive silver paste. When static electricity enters, it is guided to the middle frame for grounding through the spring contact.

[0008] In conjunction with the first aspect, in some implementations of the first aspect, the spring sheet further includes a first fixing part, a second fixing part, a first connecting part, and a second connecting part, and the middle frame further includes a grounding part; the first fixing part and the second fixing part are connected to the grounding part for fixing the spring sheet on the grounding part; the first connecting part is used to connect the first fixing part and the elastic part, and the second connecting part is used to connect the second fixing part and the elastic part.

[0009] Optionally, the first fixing part and the second fixing part are symmetrically arranged with the axis where the pressing part is located as the axis of symmetry, wherein the extension direction of the axis where the pressing part is located is the second direction. The symmetrical arrangement can make the spring contact between the spring and the first frame more stable and precise.

[0010] Optionally, the grounding part of the middle frame can be the side wall of the second receiving groove, i.e., the first fixing part and the second fixing part are connected to the side wall of the second receiving groove. The side wall of the second receiving groove can be perpendicular to the bottom surface of the second receiving groove, making the connection between the spring and the middle frame more stable, and the dimensions of the first fixing part and the second fixing part of the spring are easier to control. The side wall of the second receiving groove can also have a certain inclination angle with the bottom surface of the second receiving groove. The inclination angle is an obtuse angle with the ground of the second receiving groove, which facilitates the implementation of the welding process, prevents the appearance of the equipment from being affected during the welding process, and makes the connection between the spring and the middle frame more stable and reliable. Those skilled in the art can adjust the inclination angle of the side wall of the second receiving groove according to the needs of the installation and processing process to facilitate the installation and fixing of the spring. This application embodiment does not specifically limit this.

[0011] In this embodiment, the spring is fixed to the middle frame by the spring fixing design, which increases the stability of the spring. The spring guides static electricity from the crimping part to the fixing part and then to the grounding part of the middle frame, and the path is more reasonable.

[0012] In conjunction with the first aspect, in some implementations of the first aspect, the spring further includes a third fixing part and a fourth fixing part, the third fixing part being connected to the first fixing part, the fourth fixing part being connected to the second fixing part, and the third fixing part and the fourth fixing part being fixedly installed at the bottom of the second receiving groove.

[0013] The welding area on the bottom surface is increased by the third and fourth fixing parts, which improves the stability of the connection between the spring and the middle frame, thereby improving the stability of the spring and the first frame spring connection and making the grounding effect better.

[0014] Optionally, the first fixing part and the second fixing part are connected to the side wall of the second receiving groove by adhesive backing to pre-fix the spring piece, and the third fixing part and the fourth fixing part are installed and fixed to the second receiving groove by welding. This can increase the bottom welding area, improve the stability of the connection between the spring piece and the middle frame, and simplify the process and reduce the processing difficulty.

[0015] In conjunction with the first aspect, in some implementations of the first aspect, the bottom of the second receiving groove is provided with a limiting groove, the limiting groove extending along a first direction; the spring sheet also includes a baffle rib disposed within the limiting groove.

[0016] In this embodiment of the application, by setting a baffle, the movement path of the elastic part in the second direction is shortened, thereby increasing the elastic force of the spring sheet.

[0017] In conjunction with the first aspect, in some implementations of the first aspect, the first fixing part and the second fixing part are symmetrically arranged about the axis of the crimping part, wherein the extending direction of the axis of the crimping part is the second direction.

[0018] In this embodiment, the first fixing part and the second fixing part are symmetrically arranged on both sides of the pressing part, which makes the spring contact between the spring sheet and the first frame more stable and precise.

[0019] In conjunction with the first aspect, in some implementations of the first aspect, the second receiving groove is a V-shaped symmetrical structure, the pressing part and the elastic part are located on the central axis of the V-shape, and the first fixing part and the second fixing part are symmetrically arranged about the central axis of the V-shape, wherein the extension direction of the central axis of the V-shape is the second direction.

[0020] This embodiment of the application shortens the length of the spring sheet in the first direction, i.e., the y-axis, by setting a second receiving groove and a V-shaped symmetrical structure for the spring sheet, increases the elasticity of the spring sheet, and makes the service life of the spring sheet longer. The symmetrical setting also makes the spring sheet and the first frame more stable and precise in their spring-loaded connection.

[0021] In conjunction with the first aspect, in some implementations of the first aspect, the middle frame further includes an insulating portion disposed between the first receiving groove and the second receiving groove, for forming an insulating barrier between the first frame and the spring sheet.

[0022] This embodiment of the application provides an insulating part, which forms a natural barrier between the spring and the first frame, thus avoiding the need to place the spring near the first frame of the antenna, which would affect the antenna's functionality.

[0023] In conjunction with the first aspect, in some implementations of the first aspect, the antistatic component further includes:

[0024] A conductive sheet is mounted on the middle frame and is close to the first conductive structure. The conductive sheet and the first conductive structure have overlapping surfaces that are opposite each other, and the distance between the overlapping surfaces of the conductive sheet and the overlapping surfaces of the first conductive structure meets a preset condition.

[0025] In conjunction with the first aspect, in some implementations of the first aspect, the preset condition is that the distance between the conductive sheet and the first conductive structure is ≤1.5mm.

[0026] In conjunction with the first aspect, in some implementations of the first aspect, the overlapping surface is ≥0.5mm*0.5mm.

[0027] Optionally, the conductive sheet can be directly coupled or indirectly coupled to ground the static electricity in a timely and effective manner. For example, the conductive sheet and the first conductive structure can be attached to each other, or other conductive media can be added between the conductive sheet and the first conductive structure to enhance the discharge capability, or the conductive sheet and the first conductive structure can be arranged opposite each other with a certain gap distance between them.

[0028] In this embodiment, by setting a conductive sheet, static electricity entering through the gap between the screen and the first frame can be promptly and effectively conducted into the conductive sheet through coupling discharge, thereby connecting to the middle frame for grounding and avoiding damage to the flexible display screen.

[0029] In conjunction with the first aspect, in some implementations of the first aspect, the middle frame further includes a first boss, the first boss being close to the first conductive structure, the first boss and the first conductive structure having overlapping surfaces and being disposed opposite each other, and the distance between the first boss and the first conductive structure satisfying a preset condition.

[0030] In conjunction with the first aspect, in some implementations of the first aspect, the preset condition is that the distance between the first boss and the first conductive structure is ≤1.5mm.

[0031] In this embodiment, the first protrusion enables the timely and effective coupling discharge of static electricity entering through the gap between the screen and the first frame to the first protrusion, thereby achieving grounding and preventing damage to the flexible display screen.

[0032] In a second aspect, a foldable electronic device is provided, comprising: a flexible display screen, a flexible circuit board, and an antistatic component as described in any one of the first aspects and implementations thereof; wherein the flexible display screen is disposed above the antistatic component, and the spring, the conductive sheet, or the first boss of the antistatic component is arranged individually or in combination in the bending area of ​​the flexible circuit board.

Detailed Implementation

[0045] The following explains the terminology that may appear in the embodiments of this application.

[0046] Coupling can be understood as direct coupling and / or indirect coupling. "Coupled connection" can be understood as a direct coupling connection and / or indirect coupling connection. Direct coupling can also be called "electrical connection," which can be understood as physical contact and electrical conduction between components; it can also be understood as the form of connection between different components in a circuit structure through physical lines that can transmit electrical signals, such as copper foil or wires on a printed circuit board (PCB). "Indirect coupling" can be understood as electrical conduction between two conductors through a gap / non-contact method. In one embodiment, indirect coupling can also be called capacitive coupling, for example, signal transmission is achieved by forming an equivalent capacitance through coupling between the gaps between two conductive parts.

[0047] Connection / linking: can refer to a mechanical or physical connection. For example, A and B being connected or linked can mean that there are fasteners (such as screws, bolts, rivets, etc.) between A and B, or that A and B are in contact with each other and are difficult to separate.

[0048] Connection: The process of making two or more components conduct or connect through the above-mentioned "electrical connection" or "indirect coupling" to transmit signals / energy can be called connection.

[0049] Relative / Relative Settings: A relative setting to B can refer to A and B being face-to-face (opposite to, or face to face) settings.

[0050] Ground, or floor: can refer to at least a portion of any grounding layer, ground plane, or grounding metal layer within an electronic device (such as a mobile phone), or at least a portion of any combination of any of the aforementioned grounding layers, ground planes, or grounding components. "Ground" can be used for grounding components within an electronic device. In one embodiment, "ground" can be a ground plane formed by the frame in the electronic device or a grounding metal layer formed by a thin metal film beneath the screen.

[0051] Any of the aforementioned grounding layers, grounding plates, or grounding metal layers are made of a conductive material, which may be any of the following: copper, aluminum, stainless steel, brass and their alloys, copper foil on an insulating substrate, aluminum foil on an insulating substrate, gold foil on an insulating substrate, silver-plated copper, silver-plated copper foil on an insulating substrate, silver foil on an insulating substrate and tin-plated copper, cloth impregnated with graphite powder, a graphite-coated substrate, a copper-plated substrate, a brass-plated substrate, and an aluminum-plated substrate. Those skilled in the art will understand that grounding layers / grounding plates / grounding metal layers may also be made of other conductive materials.

[0052] Considering the radio frequency and antenna requirements of terminal devices, the small A-shell surrounding the edge of the flexible display screen is generally an insulating non-metallic product. As the connecting link between the phone screen and the body, the small A-shell's overall structure is a small frame, and its adhesive strength to the body must ensure the stability of the phone screen. To add a high-conductivity ESD protection structure to the bending area of ​​the flexible display (FPC) which is prone to ESD (electro-static discharge) failure, conductive silver paste is typically applied to the inside of the insulating small A-shell. This guides static electricity through the conductive structure and properly grounds it to the middle frame, achieving anti-static protection.

[0053] The current grounding method is extremely unstable due to the assembly process and tolerances, which leads to the spring contact with the small A-shell being in a state of partial connection, which easily generates harmonics and noise, resulting in radiated spurious emission (RSE) problems and affecting the test results of other radio frequency performance of the mobile phone.

[0054] This application provides an anti-static component that solves the problem of instability in contact-based anti-static systems for flexible displays. It can guide static electricity to ground in a timely manner, thus preventing damage to the flexible display.

[0055] The following will be combined with the appendix Figures 1 to 9 The technical solutions in this application are described below.

[0056] This application provides an anti-static component 100 including a middle frame 101, a first frame 102, and a spring 110. Static electricity is guided through the conductive structure of the first frame, and the spring and middle frame are properly grounded to achieve electrostatic protection and avoid damage to the flexible display screen.

[0057] Specifically, such as Figure 3 As shown, a first receiving groove 1011 and a second receiving groove 1012 are provided on the surface of the middle frame 101. The first receiving groove 1011 and the second receiving groove 1012 are partially connected. The first receiving groove 1011 extends along a first direction. Optionally, the first direction can be... Figure 1The Y-axis direction is shown; the first frame 102 is connected to the side of the middle frame 101. The first frame 102 includes a first extension 1021, which is installed in the first receiving groove 1011. A first conductive structure 103 is provided on the side surface of the first extension 1021 near the second receiving groove 1012; the spring piece 110 is installed in the second receiving groove 1012. The spring piece 110 includes a pressing part 111 and an elastic part 112. The spring point of the pressing part 111 contacts the first conductive structure 103. When the first frame 102 is installed on the middle frame 101, the elastic part 112 is subjected to the pressure transmitted by the pressing part 111 and moves in the second direction, providing a reverse elastic force, so that the first frame 102 and the middle frame 101 are tightly connected. The second direction is perpendicular to the first direction. Optionally, the second direction can be... Figure 1 The X-axis direction is shown.

[0058] This embodiment of the application uses a spring contact to spring-loaded the first frame, guiding static electricity from the spring contact to the middle frame, achieving timely grounding, avoiding damage to the flexible display screen, and improving the stability of the spring contact. Furthermore, the spring contact with the first conductive structure of the first frame is spring-loaded on the side of the middle frame, avoiding spring contact with the first frame on the top surface of the middle frame. Figure 1 The problem of easy connection failure of the first frame caused by the spring-loaded joint in the Z-axis direction is shown, which increases the service life and stability of the first frame.

[0059] Optionally, such as Figure 4 and Figure 5 As shown, the spring piece 110 also includes a first fixing part 113, a second fixing part 114, a first connecting part 115, and a second connecting part 116. The middle frame 101 also includes a grounding part 1013. The first fixing part 113 and the second fixing part 114 are respectively connected to the grounding part 1013 for fixing the spring piece 110 to the grounding part 1013. The first connecting part 115 is used to connect the first fixing part 113 and the elastic part 112, and the second connecting part 116 is used to connect the second fixing part 114 and the elastic part 112.

[0060] Optionally, the grounding portion 1013 of the middle frame 101 is made of a conductive material, which may be aluminum alloy, stainless steel, steel-aluminum composite die casting or titanium alloy. This embodiment of the application does not specifically limit this.

[0061] Optionally, the grounding portion 1013 of the middle frame 101 can be the side wall of the second receiving groove 1012, i.e., the first fixing portion 113 and the second fixing portion 114 are connected to the side wall of the second receiving groove 1012. Optionally, the side wall of the second receiving groove 1012 can be perpendicular to the bottom surface of the second receiving groove 1012, making the connection between the spring piece 110 and the middle frame 101 more stable, and the dimensions of the first fixing portion 113 and the second fixing portion 114 of the spring piece 110 easier to control. The side wall of the second receiving groove 1012 can also have a certain inclination angle with the bottom surface of the second receiving groove 1012, and the inclination angle is an obtuse angle with the ground of the second receiving groove 1012, which facilitates the implementation of the welding process, prevents the appearance of the equipment from being affected during the welding process, and makes the connection between the spring piece and the middle frame more stable and reliable. Those skilled in the art can adjust the inclination angle of the side wall of the second receiving groove according to the needs of the installation and processing process to facilitate the installation and fixing of the spring piece. This application embodiment does not specifically limit this.

[0062] Optionally, such as Figure 4 and Figure 5 As shown, the spring 110 also includes a third fixing part 117 and a fourth fixing part 118. The third fixing part 117 is connected to the first fixing part 113, and the fourth fixing part 118 is connected to the second fixing part 114. The third fixing part 117 and the fourth fixing part 118 are connected to the bottom of the second receiving groove 1012. By increasing the welding area of ​​the bottom surface through the third fixing part 117 and the fourth fixing part 118, the stability of the connection between the spring and the middle frame is improved, thereby improving the stability of the spring contact with the first frame and resulting in a better grounding effect.

[0063] Optionally, the first fixing part 113, the second fixing part 114, the third fixing part 117 or the fourth fixing part 118 are used to install and fix the spring piece 110 in the second receiving groove 1012 by welding, thereby improving the stability of the connection between the spring piece 110 and the middle frame 101.

[0064] Optionally, the first fixing part 113 and the second fixing part 114 are connected to the side wall of the second receiving groove 1012 by adhesive bonding to pre-fix the spring piece 110. The third fixing part 117 and the fourth fixing part 118 are installed and fixed to the second receiving groove 1012 by welding. This can increase the bottom welding area, improve the stability of the connection between the spring piece and the middle frame, and simplify the process and reduce the processing difficulty.

[0065] Optionally, such as Figure 4 and Figure 5 As shown, a limiting groove 1015 is provided at the bottom of the second receiving groove 1012, and the limiting groove 1015 extends along the first direction; the spring piece 110 also includes a baffle 119, which is provided in the limiting groove 1015, so that the movement path of the elastic part 112 in the second direction is shortened when it moves, thereby increasing the elastic force of the spring piece.

[0066] Optionally, the first fixing part 113 and the second fixing part 114 are symmetrically arranged with the axis of the pressing part 111 as the axis of symmetry, wherein the extension direction of the axis of the pressing part 111 is the second direction. The symmetrical arrangement can make the spring piece 110 and the first frame 102 more stable and precise.

[0067] Optionally, the second receiving groove 1012 has a V-shaped symmetrical structure, with the pressing part 111 and the elastic part 112 located on the central axis of the V-shape. The first fixing part 113 and the second fixing part 114 are symmetrically arranged on both sides of the V-shape. The first fixing part 113 and the second fixing part 114 have a V-shaped symmetrical structure with the central axis of the V-shape as the axis of symmetry, wherein the extension direction of the central axis of the V-shape is the second direction.

[0068] This embodiment of the application shortens the length of the spring 110 in the first direction (y-axis) by setting the second receiving groove 1012 and the V-shaped symmetrical structure of the spring 110, thereby increasing the elasticity of the spring 110 and extending its service life. The symmetrical arrangement also makes the spring 110's contact with the first frame 102 more stable and precise. The shape of the second receiving groove 1012 and the spring 110 is not limited to this in this embodiment.

[0069] Optionally, such as Figure 4 As shown, the middle frame 101 also includes an insulating portion 1014 disposed between the first receiving groove 1011 and the second receiving groove 1012. This insulating portion forms an insulating barrier between the first frame 102 and the first fixing portion 113, the second fixing portion 114, the third fixing portion 117, or the fourth fixing portion 118 of the spring piece 110, which helps to improve the stability of the spring contact between the first frame 102 and the spring piece 110. Optionally, the surface of the insulating portion 1014 is higher than the bottom surface of the first receiving groove 1011 or the second receiving groove 1012, so that the insulating portion 1014 forms a protruding structure relative to the first receiving groove 1011 or the second receiving groove 1012. When the first extension portion 1021 of the first frame 102 is installed in the first receiving groove 1011, the connection area between the first frame 102 and the middle frame 101 increases, thereby improving the stability of the connection of the first frame 102.

[0070] This embodiment of the application provides an insulating part, which forms a natural barrier between the spring and the first frame, thus avoiding the need to place the spring near the first frame of the antenna, which would affect the antenna's functionality.

[0071] Optionally, such as Figure 6 and Figure 7As shown, the first frame 102 also includes a second extension 1022. The second extension 1022 extends along a second direction and extends above the spring 110 in a third direction. The second extension 1022 can cover the spring 110 in the second direction, so that the spring 110 is blocked by the second extension 1022, thereby improving the stability of the connection.

[0072] Optionally, the first conductive structure 103 may be conductive silver paste, which is coated on the surface of the first extension 1021 near the second receiving groove 1012, so that the pressing portion 111 of the spring 110 is in contact with the conductive silver paste.

[0073] Optionally, the first frame 102 can be connected to the first receiving groove 1011 by dispensing adhesive, and this embodiment of the application does not specifically limit this.

[0074] Optionally, the first conductive structure 103 may be a conductive silver paste, which has the ability to conduct current and remove accumulated static charge, and is composed of conductive silver powder, binder, solvent and trace additives to improve performance. This embodiment of the application is not limited to this.

[0075] Optionally, the first conductive structure 103 can be disposed on the portion of the first frame 102 away from the antenna to avoid affecting the use of the antenna. This embodiment of the application does not specifically limit this. For example, when the first conductive structure 103 is conductive silver paste, the conductive silver paste can be coated in a ring along the side of the first frame 102 near the first receiving groove 1011. The coating width is set to avoid the antenna area. The pressing part 111 of the spring piece 110 is in contact with the part coated with conductive silver paste. When static electricity enters, it is guided to the middle frame 101 for grounding through the spring piece 110.

[0076] Optionally, the spring 110 can be placed in an area prone to static electricity generation, such as... Figure 2 As shown in the dashed box, the first area can be the FPC bending area of ​​the foldable electronic device. When the flexible display screen is connected to the first frame 102, the first area is very easy to enter electrostatic dust. The spring 110 can be set on both sides or the end of the first area near the chip on plastic (COP) to protect the COP. It should be noted that the position of the spring 110 and the first conductive structure 103 on the first frame 102 should also take into account the position of the antenna and maintain a corresponding distance from the antenna. The grounding position of the spring 110 can be adjusted according to the setting position of the antenna. This application embodiment does not make specific limitations on this.

[0077] In another embodiment provided in this application, the antistatic assembly 100 further includes: a conductive sheet 105, which is mounted on the middle frame 101 and close to the first conductive structure 103. The conductive sheet 105 and the first conductive structure 103 have overlapping surfaces, and the distance between the conductive sheet 105 and the first conductive structure 103 is within a certain preset condition; for example, as Figure 8 As shown, the conductive sheet 105 and the first conductive structure 103 have overlapping surfaces in the second direction and the third direction.

[0078] During use, when static electricity passes through the gap between the first outer shell and the screen, objects with different static potentials approaching each other or making direct contact will cause charge transfer. Therefore, the coupling discharge of the conductive sheet 105 creates a path between the first conductive structure 103 and the conductive sheet 105, guiding static electricity through. The charge is guided to the middle frame 101 through the conductive sheet 105, thereby achieving the grounding effect.

[0079] Optionally, the conductive sheet 105 can be directly coupled or indirectly coupled to ground the static electricity in a timely and effective manner. For example, the conductive sheet 105 and the first conductive structure 103 can be attached to each other, or other conductive media can be added between the conductive sheet 105 and the first conductive structure 103 to enhance the discharge capability, or the conductive sheet 105 and the first conductive structure 103 can be arranged opposite each other with a certain gap distance, etc. The embodiments of this application are not limited to these.

[0080] Optionally, the preset condition can be that the distance between the conductive sheet 105 and the first conductive structure 103 is less than or equal to 1.5 mm, which can achieve a good discharge protection effect, but the embodiments of this application are not limited to this.

[0081] Optionally, the overlapping surfaces of the conductive sheet 105 and the first conductive structure 103 in the second and third directions can be greater than or equal to 0.5mm*0.5mm, which can achieve a good discharge protection effect.

[0082] Optionally, the conductive sheet 105 can be a copper sheet or an aluminum alloy sheet, etc., and this embodiment does not specifically limit the specific type of conductive sheet.

[0083] Optionally, the conductive sheet 105 can be fixed to the middle frame 101 by spot welding, and this embodiment of the application does not specifically limit this.

[0084] Optionally, the conductive sheet 105 can be disposed in areas prone to static electricity generation, such as... Figure 2As shown, the first region can be the FPC bending region of the foldable electronic device, and the conductive sheet 105 can be disposed on both sides or at the end of the first region. It should be noted that the position of coupling and discharging between the conductive sheet 105 and the first conductive structure 103 on the first frame 102 should also take into account the position of the antenna and maintain a corresponding distance from the antenna. The grounding position of the conductive sheet 105 can be adjusted according to the setting position of the antenna. This embodiment of the application does not make specific limitations on this.

[0085] In this embodiment, by setting a conductive sheet, static electricity entering through the gap between the screen and the first frame can be promptly and effectively conducted into the conductive sheet through coupling discharge, thereby connecting to the middle frame for grounding and avoiding damage to the flexible display screen.

[0086] In another embodiment provided in this application, the middle frame 101 further includes a first protrusion 106, and a first conductive structure 103 is disposed on the side surface of the first frame 102 near the first protrusion 106. The first protrusion 106 and the first conductive structure 103 have overlapping surfaces, and the distance between the first protrusion 106 and the first conductive structure 103 is within a certain preset condition; for example, as Figure 9 As shown, the first boss 106 and the first conductive structure 103 have overlapping surfaces in the second direction and the third direction.

[0087] During use, when static electricity passes through the gap between the first outer shell and the screen, a path is formed between the first conductive structure 103 and the first protrusion 106, guiding the static electricity through. The charge is directly guided to the first protrusion 106, thereby achieving the grounding effect.

[0088] Optionally, the preset condition can be that the distance between the first protrusion 106 and the first conductive structure 103 is less than or equal to 1.5 mm, which can achieve a good discharge protection effect, but the embodiments of this application are not limited to this.

[0089] Optionally, the overlapping area of ​​the first protrusion 106 and the first conductive structure 103 in the second and third directions can be greater than or equal to 0.5mm*0.5mm, which can achieve a good discharge protection effect.

[0090] Optionally, the first boss 106 can be disposed in an area prone to static electricity generation, such as... Figure 2 As shown, the first region can be the FPC bending region of the foldable electronic device, and the first protrusion 106 can be set on both sides or the end of the first region. It should be noted that the coupling discharge position of the first protrusion 106 and the first conductive structure 103 on the first frame 102 should also take into account the position of the antenna and maintain a corresponding distance from the antenna. The grounding position of the first protrusion 106 can be adjusted according to the setting position of the antenna. This application embodiment does not make specific limitations on this.

[0091] In this embodiment, the first protrusion 106 enables the timely and effective conduction of static electricity entering through the gap between the screen and the first frame 102 into the first protrusion 106 through coupling discharge, thereby achieving the purpose of grounding and avoiding damage to the flexible display screen.

[0092] This application also provides a foldable electronic device, which can be a mobile phone, tablet computer, watch, e-reader, laptop computer, wearable device, or other electronic device with folding functionality. This application uses a foldable mobile phone as an example for illustration.

[0093] Foldable electronic devices may include flexible displays, flexible printed circuits (FPCs), and the antistatic component 100 provided in any of the foregoing embodiments.

[0094] The flexible display screen is positioned above the anti-static component 100. The flexible display screen can be highly flexible and bendable, providing users with a new interaction method based on its bendability. The display panel of the flexible display screen can be any of the following: liquid crystal display (LCD), organic light-emitting diode (OLED), active-matrix organic light-emitting diode (AMOLED), flex light-emitting diode (FLED), quantum dot light-emitting diode (QLED), etc. This application embodiment does not limit the specific type of display panel.

[0095] Optionally, the antenna of the foldable electronic device can be disposed within the first frame 102. For example, it can be disposed within the foldable electronic device, close to the first frame 102 and at a certain distance from the first conductive structure 103, making the antenna closer to the outside of the foldable electronic device and achieving better signal transmission. It should be noted that "disposable within the first frame 102" means that the antenna can be placed flush against the first frame 102, or it can be placed close to the first frame 102, for example, there can be a small gap between the antenna and the first frame 102. The antenna can also be disposed in other locations within the foldable electronic device, such as a transparent structure embedded in a flexible display screen.

[0096] For example, the hinge of the foldable electronic device is located in the second direction, the foldable device can be folded along the first direction, and the flexible display screen can be divided into upper and lower regions, for example... Figure 1 and Figure 2 A first region is provided, with the flexible display FPC positioned near the bottom of the first region. The spring tab 110, conductive sheet 105, or first protrusion 106 can be arranged at the bottom of the first region. Since the flexible display FPC area is prone to static electricity, the arrangement of the anti-static component 100 allows for better grounding of static electricity, thus protecting the flexible display. Alternatively, the conductive sheet 105 and first protrusion 106 can be arranged at the bottom of the first region, with the spring tab 110 arranged on both sides of the first region. This allows for flexible adjustment based on the position and space of the foldable device, making the layout of the anti-static component 100 more reasonable and practical. It should be noted that the position and quantity of the spring tab 110, conductive sheet 105, or first protrusion 106 are not limited to these in this embodiment.

[0097] The embodiments of this application provide a foldable electronic device that can guide static electricity to ground in a timely manner to avoid damaging the flexible display screen.
