Abstract

Embodiments of the present application relate to the field of folding structures, and disclose a folding assembly and a terminal device, which mitigate the problem that a flexible screen is prone to cracks after being bent multiple times. A specific solution is: a first door panel of a folding assembly comprises a slide rail and a slide block that are in a sliding connection, and the slide block may slide along a direction perpendicular to a rotation axis of the folding assembly. The slide block is configured to connect to a bending area of the flexible screen. When the bending area of the flexible screen is folded or unfolded, the internal stress in the bending area is transmitted to the slide block, so that the slide block slides relative to the slide rail, and the internal stress is relieved. Therefore, the problem of delamination or cracks of the bending area of the flexible screen caused by the internal stress is effectively mitigated.

Description

Folding components and terminal equipment

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on September 27, 2023, with application number 202311271143.1 and application name “Folding component and terminal device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The embodiments of the present application relate to the field of folding structures, and in particular to a folding assembly and a terminal device. Background Art

[0003] With the continuous development of display technology, foldable devices (such as foldable phones) are becoming a trend in future mobile electronic products. When unfolded, these devices can provide a larger display area, improving viewing experience. When folded, they can be compact, making them easier to carry.

[0004] Typically, a terminal device includes a flexible screen and a folding assembly that supports the flexible screen. The performance of the folding assembly directly affects the device's usability. For example, if the folding assembly performs poorly, the flexible screen's folding area could crack after repeated folding during use.

[0005] Summary of the Invention

[0006] The embodiments of the present application provide a folding assembly and a terminal device to improve the problem that the bending area of ​​the flexible screen is prone to cracking after multiple bending.

[0007] In order to achieve the above objectives, this application adopts the following technical solutions.

[0008] In a first aspect, embodiments of the present application provide a folding assembly. The folding assembly includes a first door panel, a second door panel, and a third door panel. The second door panel is pivotally connected to one side of the first door panel. The third door panel is pivotally connected to the side of the first door panel facing away from the second door panel. The second door panel includes a body and a slider. The body is provided with a slide rail extending perpendicularly to the rotation axis of the folding assembly; the slider is movably connected to the slide rail. The slider can slide along the extension direction of the slide rail, that is, the slider's sliding direction is perpendicular to the rotation axis of the folding assembly. When the surface of the slider facing away from the slide rail is connected to the bending zone of the flexible screen, the bending zone deforms when the flexible screen bends. The resulting internal stress is transmitted to the slider, which has a force component perpendicular to the rotation axis. This force component can push the slider to slide along the extension direction of the slide rail, thereby releasing the internal stress. This avoids the problem of internal delamination in the bending zone of the flexible screen caused by the inability to release internal stress, and also helps to solve problems such as cracks caused by internal stress in the bending zone after multiple bending. Similarly, when the bending area of ​​the flexible screen is unfolded, the deformation of the bending area produces a force in the opposite direction of the aforementioned internal stress. This force causes the slider to slide in the opposite direction on the slide rail and reset, thereby releasing internal stress, reducing cracks in the bending area and avoiding delamination problems in the bending area.

[0009] In combination with the first aspect, in some feasible ways, the surface of the slider away from the slide rail is not parallel to the extension direction of the slide rail. When the slider is placed horizontally away from the surface of the slide rail, the slider's own gravity causes the slider to have a tendency to move downward on the slide rail. When not subject to other external forces, this movement trend can make the slider and the slide rail have a relatively determined positional relationship, so that the slider and the slide rail can be positioned. If the bending area and the slider are connected when the slider is placed horizontally away from the surface of the slide rail, the relative position of the slider and the bending area is easy to determine, which can improve the assembly accuracy of the bending area and the slider, and avoid problems such as arching of the flexible screen due to low assembly accuracy.

[0010] In combination with the first aspect, in some feasible embodiments, the angle between the surface of the slider facing away from the slide rail and the extension direction of the slide rail is 0° to 30°, and the opening of the angle faces away from the first door panel. In this way, when the slider is placed horizontally away from the surface of the slide rail, the slider's own gravity causes the slider to have a tendency to move on the slide rail toward the side close to the first door panel. When not subject to other external forces, this movement trend can cause the slider to be located at a position of the slide rail close to the first door panel. In this state, connecting the bending area and the slider can improve the assembly accuracy of the bending area and the slider. In addition, since the aforementioned angle is small, when the slider is placed horizontally away from the surface of the slide rail, the internal stress of the bending area causes the slide rail to slide along the side away from the first door panel. The slider needs to do less work to overcome gravity, which is more conducive to the sliding of the slider relative to the slide rail and the release of internal stress.

[0011] In combination with the first aspect, in some feasible embodiments, the second door panel further includes a deformable layer. The deformable layer is located between the slide rail and the slider; the material of the deformable layer includes glue. Since the material of the deformable layer includes glue, the glue will deform under the action of an external force. When the slider applies a force to the deformable layer, the layer deforms, and the deformation causes the slide rail and the slider to slide relative to each other. In addition, the presence of the deformable layer prevents the slide rail from directly contacting the slider, thus avoiding loud noise caused by direct contact between a rigid slide rail and a rigid slider. Since the slide rail and the slider do not directly contact each other, the manufacturing precision of the slide rail and the slider can be lower, saving manufacturing costs.

[0012] In conjunction with the first aspect, in some possible implementations, the second door panel further includes a lubricating layer. The lubricating layer is located between the slide rail and the slider; the lubricating layer comprises a lubricant. The provision of the lubricating layer comprising a lubricant can reduce the noise generated by the direct sliding movement of the slide rail and the slider.

[0013] In combination with the first aspect, in some feasible embodiments, the second door panel further includes an elastic limiting portion. The extension direction of the elastic limiting portion is parallel to the extension direction of the slide rail; one end of the elastic limiting portion is connected to the slider, and the other end is connected to the main body or the slide rail. Thus, the direction of the elastic force of the elastic limiting portion is parallel to the extension direction of the slide rail, and the elastic force of the elastic limiting portion is parallel to the movement direction of the slide rail. If the elastic limiting portion applies tension or pressure to the slider, the elastic force causes the slider to have a tendency to move on the slide rail. Before the bending area of ​​the flexible screen is connected to the slider, if the external force applied to the slider is small, the elastic limiting portion can store the external force to prevent the slider from sliding arbitrarily relative to the slide rail and locate the position of the slider on the main body. Connecting the bending area and the slider in this case is conducive to determining the relative position of the main body and the bending area, reducing the dislocation between the main body and the bending area, and avoiding arching of the flexible screen.

[0014] In conjunction with the first aspect, in some possible implementations, the second door panel further includes a stopper. The stopper is located on a side of the slider facing away from the elastic stopper and is connected to the slide rail or the body. When the slider slides relative to the slide rail until it abuts the stopper, the elastic stopper is in a compressed state or a free state. If the elastic stopper is in the compressed state, it tends to cause the slider to slide relative to the slide rail in a direction away from the elastic stopper. Furthermore, because the stopper abuts the side of the slider facing away from the elastic stopper, the stopper prevents the slider from sliding in a direction away from the elastic stopper. The elastic stopper and the stopper function to position the slider on the slide rail. In this state, the slider and the bending zone are connected, preventing misalignment between the slider and the bending zone and preventing the bending zone from bulging. Similarly, if the elastic stopper is in the free state, the elastic stopper cannot force the slider to slide toward the elastic stopper. Similarly, the elastic stopper and the stopper function to position the slider on the slide rail. Connecting the slider and the bending zone in this state can also prevent dislocation between the slider and the bending zone and prevent the bending zone from arching.

[0015] In conjunction with the first aspect, in some achievable embodiments, the second door panel further comprises an adhesive layer. The adhesive layer is connected to a surface of the slider facing away from the slide rail. In this way, the end of the slider facing away from the slide rail can be connected to the bending region of the flexible screen via the adhesive layer.

[0016] In conjunction with the first aspect, in some practicable embodiments, the vertical projection of the adhesive layer on the slider is located inside the slider. This prevents the adhesive layer from overflowing the slider, for example, from overflowing onto the connection between the slide rail and the slider, thereby affecting the smoothness of the sliding of the slider and the slide rail.

[0017] In conjunction with the first aspect, in some achievable embodiments, the slide rail includes a base, a first limiting plate, and a second limiting plate. The base is connected to the body, and a surface of the base facing away from the body is provided with a chute, the chute extending perpendicularly to the rotation axis of the folding assembly. One end of the first limiting plate and one end of the second limiting plate are both connected to the base, and the other ends of the first limiting plate and the second limiting plate are both free ends and located at the opening of the chute. The slider extends into the chute and is slidably connected thereto, and the free ends of the first limiting plate and the second limiting plate abut against the slider. Because the chute extends perpendicularly to the rotation axis of the folding assembly and the slider extends into the chute and is slidably connected thereto, the slider's movement direction is perpendicular to the rotation axis of the folding assembly. Furthermore, because the first and second free ends are located at the opening of the chute and both abut against the slider, the first and second free ends can prevent the slider from sliding out of the chute opening, thereby constraining the slider's movement direction to be perpendicular to the rotation axis of the folding assembly.

[0018] In conjunction with the first aspect, in some achievable embodiments, the base, the first limiting plate, and the second limiting plate are connected to form an integrally formed part. In this way, the base, the first limiting plate, and the second limiting plate can be formed at one time, simplifying the forming process of the slide rail.

[0019] In conjunction with the first aspect, in some practicable embodiments, the slide rail further includes a connector, and the first limit plate and the base are connected via the connector. Thus, during assembly of the slider and the slide rail, the slider can be first placed in the slide groove, and then the first limit plate and the base can be connected using the connector, simplifying the assembly process.

[0020] In conjunction with the first aspect, in some practicable embodiments, the base and the body are connected to form an integrally formed part, so that the base and the body do not need to be assembled, simplifying the assembly process.

[0021] In combination with the first aspect, in some feasible embodiments, the second door panel includes a plurality of such sliders, and the main body is provided with a plurality of such slide rails. The plurality of such slide rails are arranged at intervals along the rotation axis of the folding assembly, and one such slide rail is connected to one such slider. Thus, when the slider of the second door panel is connected to the bending zone, during the bending process of the bending zone, each portion of the bending zone along the rotation axis of the folding assembly has internal stress. In this way, by arranging a plurality of slide rails and a plurality of sliders along the rotation axis of the folding assembly, the internal stress in the plurality of regions of the bending zone along the rotation axis of the folding assembly is released, thereby further improving the problems of cracks and delamination caused by internal stress.

[0022] In conjunction with the first aspect, in some achievable embodiments, when the folding assembly is in the unfolded state, the slider is located at the end of the slide rail facing the second door panel. This allows the slider of the second door panel to move only along the slide rail in a direction away from the first door panel. That is, when the folding assembly rotates from the unfolded state to the folded state, the slider can only slide along the slide rail in a direction away from the first door panel. This sliding direction is the same as the direction of the force exerted by the bending zone of the flexible screen on the slider when the bending zone bends. This facilitates the release of internal stress when the bending zone bends.

[0023] In combination with the first aspect, in some feasible embodiments, the third door panel includes a body and a sliding rail, and an extension direction of the sliding rail is perpendicular to the rotation axis of the folding assembly.

[0024] In combination with the first aspect, in some achievable embodiments, the third door panel further includes a deformation layer. The deformation layer is located between the slide rail and the slider; and the material of the deformation layer includes glue.

[0025] In conjunction with the first aspect, in some practicable embodiments, the third door panel further includes an elastic limiting portion, wherein an extension direction of the elastic limiting portion is parallel to an extension direction of the slide rail, and one end of the elastic limiting portion is connected to the slider, and the other end is connected to the body or the slide rail.

[0026] In conjunction with the first aspect, in some practicable embodiments, the third door panel further includes a stop portion. The stop portion is located on a side of the slider facing away from the elastic limiting portion, and the stop portion is connected to the slide rail or the body. When the slider slides relative to the slide rail until it abuts the stop portion, the elastic limiting portion is in a compressed state or a free state.

[0027] In a second aspect, an embodiment of the present application provides a terminal device. The terminal device includes a flexible screen, and any one of the folding components provided in the first aspect above; the bending area of ​​the flexible screen is connected to the surface of the slider facing away from the slide rail. Because the slider of the folding component can slide relative to the slide rail. The bending area of ​​the flexible screen and the slider can slide relative to the slide rail together. During the unfolding or folding process of the terminal device, the bending area of ​​the flexible screen unfolds or bends accordingly, and the internal stress of the flexible screen is transmitted to the slider, and then slides relative to the slide rail together with the slider, so that the internal stress is released, thereby avoiding internal stress causing delamination of the bending area or cracks in the bending area.

DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solutions and advantages of this application clearer, this application will be further described in detail below with reference to the accompanying drawings.

[0040] Hereinafter, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified with "first," "second," etc., may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0041] In addition, in this application, directional terms such as "upper" and "lower" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they can change accordingly according to changes in the orientation of the components in the drawings.

[0042] The present application provides a terminal device, which may be, for example, a mobile phone, a tablet computer (pad), a personal digital assistant (PDA), a television, etc. For the convenience of description, the following description takes a mobile phone as an example.

[0043] FIG1 is a schematic diagram of the structure of a terminal device 10. Referring to FIG1 , the terminal device 10 includes a flexible screen 20 and a folding assembly 100. The flexible screen 20 and the folding assembly 100 are connected, and the folding assembly 100 is used to support the flexible screen 20.

[0044] Wherein, the flexible screen 20 is used to display images. In some embodiments of the present application, the flexible screen 20 is a multi-layer structure. The flexible screen 20 includes, for example, a touch panel (TP) module, a liquid crystal display (LCD) module, and a backlight unit (BLU). Alternatively, in other embodiments of the present application, the flexible screen 20 may be an organic light emitting diode (OLED) display screen. In still other embodiments of the present application, the flexible screen 20 may be an active matrix organic light emitting diode (AMOLED) display screen.

[0045] Figure 2 is an enlarged schematic diagram of point A in Figure 1. Referring to Figure 2, the folding assembly 100 is connected to the flexible screen 20. The flexible screen 20 includes a bending region 21 and a non-bending region 22 that are interconnected. Both the bending region 21 and the non-bending region 22 are connected to one side of the folding assembly 100.

[0046] The folding assembly 100 includes a first door panel 110, a second door panel 120 and a third door panel 130. The second door panel 120 and the third door panel 130 are respectively rotatably connected to the opposite sides of the first door panel 110. The second door panel 120 can rotate relative to one side of the first door panel 110, and the third door panel 130 can rotate relative to the other side of the second door panel 120, so that the second door panel 120 and the third door panel 130 can rotate together around the rotation axis n of the folding assembly 100 (as shown in Figure 1), thereby allowing the folding assembly 100 to be unfolded or folded. In the process of the folding assembly 100 rotating from the unfolded state to the folded state, the second door panel 120 and the third door panel 130 both rotate relative to the first door panel 110, so that the first door panel 110, the second door panel 120 and the third door panel 130 together enclose an arc-shaped space C as shown in Figure 2, which accommodates the bending area 21 of the flexible screen 20. Figure 3 is a structural schematic diagram of the rotating shaft assembly 01 and the display screen 02 in the related art. 3 , the hinge assembly 01 includes a middle plate 03 and two rotating plates 04 , which are rotatably connected to opposite sides of the middle plate 03 . The two rotating plates 04 are connected to the display screen 02 via adhesive members 05 .

[0047] When hinge assembly 01 is in the folded state as shown in Figure 3, display screen 02 is also bent, causing the display screens 02 to squeeze each other. For example, the right side of display screen 02 in Figure 3 exerts a force f on the left side. Furthermore, because display screen 02 is a multi-layer structure, after multiple folding and unfolding, the multi-layer structure can experience delamination, cracks, and other issues.

[0048] The folding assembly 100 provided in the embodiment of the present application can effectively improve the problem of delamination and cracking of the flexible screen 20 after multiple bending.

[0049] As shown in FIG2 , the second door panel 120 includes a body 121 and a slider 123. A slide rail 122 is provided on the body 121. The slide rail 122 extends perpendicular to the rotation axis n (shown in FIG1 ) of the folding assembly 100. The slider 123 is movably connected to the slide rail 122. For example, the slider 123 is slidably connected to the slide rail 122.

[0050] The slider 123 can slide along the extension direction of the slide rail 122. When the slider 123 is away from the surface of the slide rail 122 and connected to the bending area 21 of the flexible screen 20, when the bending area 21 of the flexible screen 20 bends around the rotation axis n, the bending area 21 is deformed, and the internal stress F after deformation is transmitted to the slider 123, so that the slider 123 and the bending area 21 slide together along the extension direction of the slide rail 122, releasing the internal stress F. It effectively improves the problem of internal delamination of the bending area 21 caused by the internal stress F of the bending area 21, and is also conducive to solving problems such as cracks caused by internal stress of the bending area 21 after multiple bending. Similarly, when the bending area 21 of the flexible screen 20 is unfolded, the deformation of the bending area 21 generates a force in the opposite direction of the aforementioned internal stress F. This force causes the slider 123 to slide back and reset, which also achieves the purpose of releasing internal stress, reducing cracks and delamination of the bending area 21.

[0051] Furthermore, during the bending process of the bending zone 21, the internal stress F is insufficient to propel the entire bending zone 21 to move. Consequently, the distance that the bending zone 21 and the slider 123 move relative to the body 121 is relatively short, and this distance has little impact on the position of the entire bending zone 21. For example, this distance does not cause the junction between the bending zone 21 and the non-bending zone 22 to shift relative to the entire second door panel 120, and thus has little impact on the flatness of the bending zone 21 and the non-bending zone 22. In other words, the second door panel 120 can release the internal stress of the bending zone 21 via the slider 123, while the sliding distance of the slider 123 has little impact on the position and flatness of the bending zone 21, thus avoiding the problem of arching at the junction between the bending zone 21 and the non-bending zone 22.

[0052] In some embodiments, the folding assembly 100 further includes a middle frame 31, to which the first door panel 110, the second door panel 120, and the third door panel 130 are all rotatably connected. Exemplarily, the middle frame 31 includes a support plate and a frame surrounding the support plate. The middle frame 31 is connected to the non-bending region 22 of the flexible screen 20. For example, the middle frame 31 and the non-bending region 22 are bonded.

[0053] As described above, the second door panel 120 is rotatably connected to the first door panel 110. The embodiments of the present application do not limit the manner in which the second door panel 120 and the first door panel 110 are rotatably connected. In some embodiments, the second door panel 120 and the first door panel 110 are hinged. In other embodiments, the first door panel 110 and the middle frame 31 are rotatably connected, and the second door panel 120 and the middle frame 31 are rotatably connected, thereby achieving the rotational connection between the second door panel 120 and the first door panel 110.

[0054] For ease of description, the direction of the rotation axis n is defined as the z-direction, and the extension direction of the slide rail 122 is defined as the x-direction, with the x-direction and the z-direction being described relative to each other. It is understood that during the unfolding or folding process of the folding assembly 100, the extension direction x-direction of the slide rail 122 continuously changes, but remains perpendicular to the z-direction.

[0055] Figure 4 is a schematic structural diagram of the folding assembly 100 provided in an embodiment of the present application in an unfolded state. In Figure 4, the second door panel 120 has multiple sliders 123, and multiple slide rails 122 are arranged on the main body 121. The multiple slide rails 122 are arranged at intervals along the z direction, and the multiple slide rails 122 are all connected to the main body 121, and one slide rail 122 is connected to one slider 123. During the bending process of the bending zone 21 (as shown in Figure 2), each part of the bending zone 21 along the z direction has internal stress F (as shown in Figure 2). In this way, multiple slide rails 122 and multiple sliders 123 are arranged at intervals along the z direction, so that the internal stresses in multiple areas of the bending zone 21 along the z direction are released, further improving the cracks and delamination problems caused by internal stress.

[0056] The embodiment of the present application does not limit the number of the sliding rails 122 on the second door panel 120. For example, the number of the sliding rails 122 can be one, two, three or more.

[0057] In embodiments where the second door panel 120 includes multiple slide rails 122, the present invention does not restrict the positional relationship of the multiple slide rails 122 in the x-direction. For example, in FIG4 , the multiple slide rails 122 are aligned at opposite ends along the x-direction. In other embodiments, the multiple slide rails 122 may not be aligned at opposite ends along the x-direction; for example, some slide rails 122 may be closer to the first door panel 110 than the remaining slide rails 122.

[0058] In Figure 4 , when the folding assembly 100 is in the unfolded state, the slider 123 is located at the end of the slide rail 122 facing the first door panel 110. This allows the slider 123 of the second door panel 120 to move only in the direction of the slide rail 122 away from the first door panel 110 (as indicated by the arrow on the slider 123 in Figure 4 ). Specifically, when the folding assembly 100 rotates from the unfolded state to the folded state, the slider 123 can only slide in the direction of the slide rail 122 away from the first door panel 110. This sliding direction is the same as the direction of the force exerted by the bending zone 21 on the slider 123 when the bending zone 21 bends. This facilitates the release of internal stress during bending of the bending zone 21. It should be understood that the aforementioned aligning of the sliding direction and the direction of the force exerted by the bending zone 21 on the slider 123 is not limited to a 0° angle between the two directions. For example, the angle between the two directions can range from 0° to 90°, or can be 0°, 10°, 20°, 30°, 40°, 50°, or 90°, etc.

[0059] In some embodiments, when the folding assembly 100 is in the folded state shown in FIG2 , the slider 123 is located at the end of the slide rail 122 facing away from the first door panel 110. Similarly, when the folding assembly 100 is rotated from the folded state to the unfolded state, the slider 123 can only slide along the slide rail 122 toward the first door panel 110. This sliding direction is the same as the direction of the force exerted by the bending zone 21 on the slider 123 when the bending zone 21 bends, which facilitates the release of internal stress when the bending zone 21 bends.

[0060] It can be understood that in some embodiments, the length of the slide rail 122 along the x direction is longer. When the folding component 100 is in the unfolded state or the folded state, the slider 123 is located at a non-end position of the slide rail 122. Under the action of the stress in the bending area 21, the slider 123 can slide relative to the slide rail 122.

[0061] Figure 5 is a schematic diagram of the exploded structure of the folding assembly 100 and the flexible screen 20 provided in an embodiment of the present application. Figure 5 shows a schematic diagram of the folding assembly 100 on the DD cross-section in Figure 4. In Figure 5, the folding assembly 100 and the flexible screen 20 are both in the unfolded state.

[0062] In Figure 5, the bending area 21 of the flexible screen 20 is connected to the main body 121 of the second door panel 120 via an adhesive layer 201. In other words, the second door panel 120 also includes an adhesive layer 201, which is connected to the surface of the slider 123 facing away from the slide rail 122. The slider 123 is connected to the bending area 21 of the flexible screen 20 via the adhesive layer 201. In this way, when the slider 123 slides relative to the slide rail 122, the slider 123, the adhesive layer 201, and the bending area 21 move synchronously and slide relative to the slide rail 122 together. Accordingly, the internal stress of the bending area 21 during the bending and unfolding process is transferred to the slider 123 through the adhesive layer 201 and released.

[0063] In some embodiments, the vertical projection of the adhesive layer 201 on the slider 123 is located within the slider 123. This prevents the adhesive layer 201 from overflowing the slider 123, for example, from overflowing onto the connection between the slide rail 122 and the slider 123, thereby affecting the smooth sliding of the slider 123 and the slide rail 122. It is understood that if the adhesive layer 201 has poor fluidity, the vertical projection of the adhesive layer 201 on the slider 123 may be partially located outside the slider 123. Due to poor fluidity, the adhesive layer 201 is less likely to flow to other areas (such as the end surface of the slider 123 facing the slide rail 122), thereby minimizing the impact on other areas.

[0064] Typically, during the process of assembling the bending area 21 and the second door panel 120 of the flexible screen 20, in order to facilitate determining the relative positions of the main body 121 and the bending area 21, the bending area 21 and the second door panel 120 of the flexible screen 20 can be assembled when the folding assembly 100 and the flexible screen 20 are both in an unfolded state.

[0065] In some embodiments, the adhesive layer 201 and the slider 123 can be connected first, and then the bending area 21 and the surface of the adhesive layer 201 facing away from the slider 123 can be connected. Alternatively, in other embodiments, the adhesive layer 201 and the bending area 21 can be connected first, and then the slider 123 and the surface of the adhesive layer 201 facing away from the bending area 21 can be connected. For the two connection processes mentioned above, to determine the relative position of the main body 121 and the bending area 21, it is necessary to determine the position of the bonding point between the bending area 21 and the adhesive layer 201, as well as the relative position of the adhesive layer 201 and the main body 121. Because the slider 123 slides relative to the slide rail 122, the adhesive layer 201 and the slider 123 are connected. Therefore, when the folding assembly 100 and the flexible screen 20 are both in the unfolded state, positioning the slider 123 on the main body 121 and then connecting the slider 123, the adhesive layer 201 and the bending area 21 can ensure that the main body 121 and the bending area 21 have a determined positional relationship.

[0066] Figure 6 is a schematic structural diagram of a slider 123 and a slide rail 122 provided in an embodiment of the present application. Referring to Figure 6, the second door panel 120 also includes an elastic limiting portion 124, the extension direction of the elastic limiting portion 124 is the x-direction, one end of the elastic limiting portion 124 is connected to the slider 123, and the other end is connected to the body 121 or the slide rail 122. The elastic limiting portion 124 is elastic, and the direction of the elastic force of the elastic limiting portion 124 is along its extension direction x-direction. Because the direction in which the slider 123 moves relative to the slide rail 122 is the x-direction, the elastic force of the elastic limiting portion 124 is in the direction of movement of the slide rail 122. If the elastic limiting portion 124 applies an elastic force to the slider 123, the elastic force causes the slider 123 to have a tendency to move on the slide rail 122.

[0067] The aforementioned extension direction of the elastic limiting portion 124 refers to the direction in which the elastic limiting portion 124 deforms when tension or pressure is applied, and the elastic limiting portion 124 returns to its original position after the tension or pressure is removed. If the elastic limiting portion 124 can deform in multiple directions when tension or pressure is applied, any direction can be designated as the aforementioned extension direction.

[0068] Please return to Figure 5. When the folding assembly 100 is in the unfolded state shown in Figure 5, the elastic properties of the elastic limiter 124 keep the slider 123 stationary relative to the slide rail 122. For example, the elastic limiter 124 will push or pull the slider 123 until the force exerted by the elastic limiter 124 on the slider 123 prevents the slider 123 from moving relative to the slide rail. In this way, before the bending zone 21 of the flexible screen 20 is connected to the slider 123, if the external force applied to the slider 123 is small, the elastic limiter 124 can convert the external force into elastic potential energy. The elastic limiter 124 can prevent the slider 123 from sliding freely relative to the slide rail 122 and locate the position of the slider 123 on the body 121. In this case, connecting the bending zone 21 and the slider 123 is conducive to determining the relative position of the body 121 and the bending zone 21, reducing the misalignment between the body 121 and the bending zone 21. For example, when the slider 123 is stationary relative to the slide rail 122, the adhesive layer 201 connects to the slider 123, and the bending area 21 is connected to the slider 123 via the adhesive layer 201. Even if the bending area 21 can slide through the slider 123 and the slide rail 122, the body 121 and the bending area 21 maintain a fixed positional relationship. This improves the assembly accuracy of the flexible screen 20 and the folding assembly 100 and prevents the bending area 21 from arching due to misaligned connection.

[0069] Furthermore, when the folding assembly 100 folds from the unfolded state to the folded state, the slider 123 slides relative to the slide rail 122, pushing the elastic stopper 124, causing the elastic stopper 124 to store elastic potential energy. During the process of unfolding the folding assembly 100 from the folded state to the unfolded state, the elastic potential energy pushes the slider 123 to slide relative to the slide rail 122, causing the slider 123 to drive the bending region 21 back to its position in the unfolded state.

[0070] The present embodiment of the present application does not limit the material of the elastic limiting portion 124. For example, the material of the elastic limiting portion 124 includes sponge, metal, or rubber. The present embodiment of the present application does not limit the structure of the elastic limiting portion 124. For example, the elastic limiting portion 124 is a spring or foam layer.

[0071] Figure 7 is a schematic diagram of the structure of the N side in Figure 6. Referring to Figure 7, the second door panel 120 further includes a stopper 125. The stopper 125 is located on the side of the slider 123 facing away from the elastic stopper 124. The stopper 125 is connected to the slide rail 122 or the body 121. When the slider 123 slides relative to the slide rail 122 until it abuts the stopper 125 (as shown in Figure 7), the elastic stopper 124 is in a compressed state or a free state.

[0072] In some embodiments, when the slider 123 slides and abuts the stopper 125, the elastic stopper 124 is in a compressed state, and the elastic stopper 124 tends to cause the slider 123 to slide relative to the slide rail 122 in a direction away from the elastic stopper 124. Furthermore, because the side of the slider 123 facing away from the elastic stopper 124 abuts the stopper 125, when the elastic stopper 124 applies a spring force to the slider 123, the stopper 125 prevents the slider 123 from sliding in a direction away from the elastic stopper 124. The elastic stopper 124 and the stopper 125 serve to position the slider 123 on the slide rail 122, thereby positioning the slider 123 on the body 121. When the folding assembly 100 is in the unfolded state shown in FIG5 and is about to be connected to the bending zone 21, without being affected by external forces, the elastic limiting portion 124 and the stop portion 125 assist each other to determine the relative positions of the slider 123 and the bending zone 21. In this state, the slider 123 and the bending zone 21 are connected to avoid dislocation between the slider 123 and the bending zone 21 and to avoid arching of the bending zone 21.

[0073] In other embodiments, when the slider 123 slides until it abuts the stopper 125, the elastic stopper 124 is in a free state. The elastic stopper 124 cannot drive the slider 123 away from the stopper 125. Similarly, in the absence of external forces, the elastic stopper 124 and the stopper 125 serve to position the slider 123 on the slide rail 122, thereby positioning the slider 123 on the body 121. Connecting the slider 123 and the bending zone 21 in this state also prevents misalignment between the slider 123 and the bending zone 21, thereby preventing the bending zone 21 from arching.

[0074] The embodiment of the present application does not limit the structure of the stop portion 125 . When the stop portion 125 abuts the slide rail 122 , the stop portion 125 can limit the slider 123 from continuing to move toward the stop portion 125 .

[0075] As described above, the stopper 125 is connected to the slide rail 122 or the body 121. In embodiments where the stopper 125 is connected to the slide rail 122, the connection between the stopper 125 and the slide rail 122 may be, for example, a snap connection, adhesive connection, or screw connection, or the stopper 125 and the slide rail 122 may be connected as an integral part. Similarly, in embodiments where the stopper 125 is connected to the body 121, the connection between the stopper 125 and the body 121 may be, for example, a snap connection, adhesive connection, or screw connection, or the stopper 125 and the body 121 may be connected as an integral part.

[0076] Referring again to Figure 7 , in the example shown in Figure 7 , the surface of slider 123 facing away from rail 122 is not parallel to the extension direction of rail 122. As previously described, the internal stress F generated by the deformation of bending region 21 is transmitted to slider 123, causing it to move along the x-direction, the extension direction of rail 122. Because bending region 21 is connected to the surface of slider 123 facing away from rail 122, the bending region 21 bends along an arc. The internal stress F generated by the deformation of bending region 21 is not parallel to the surface of slider 123 facing away from rail 122. Compared to the example in which the surface of slider 123 facing away from rail 122 is parallel to the x-direction, the x-direction component Fx of the internal stress F is relatively larger, effectively pushing slider 123 to move in the x-direction and thus better relieving the internal stress F.

[0077] In addition, please return to Figure 5. During the assembly of the bending area 21 of the flexible screen 20 and the second door panel 120, the slider 123 of the second door panel 120 can be oriented upward in Figure 5, that is, the slider 123 is located above the main body 121. The flexible screen 20 is located above the slider 123 and then connected to the slider 123. Because the surface of the slider 123 facing away from the slide rail 122 is not parallel to the extension direction of the slide rail 122. The slider 123 has a tendency to slide downward under its own gravity. This tendency can make the slider 123 located at the lowest end of the slide rail 122. It is beneficial to locate the position of the slider 123 that is not connected to the bending area 21. After positioning the slider 123, connecting the bending area 21 and the slider 123 is beneficial to determine the relative position of the main body 121 and the bending area 21, and reducing the dislocation between the main body 121 and the bending area 21.

[0078] In Figure 7 , the angle α between the surface of the slider 123 facing away from the slide rail 122 and the extension direction of the slide rail 122 is between 0° and 30° (excluding 0°), and the opening at angle α faces away from the first door panel 110. For example, angle α can be 1°, 5°, 10°, 12°, 15°, 20°, 25°, 28°, 30°, and so on. Because the opening at angle α faces away from the first door panel 110, when the second door panel 120 rotates about the rotation axis n (as shown in Figure 4 ), the bending region 21 rotates relative to the surface of the slider 123 facing away from the slide rail 122, pulling the slider 123 toward the bending region 21. Because the opening at angle α faces away from the first door panel 110, the slide rail 122 is closer to the bending region 21 at the end of the slider 123 facing away from the first door panel 110 than at the end of the slider 123 facing the first door panel 110. In this way, when the slide rail 122 slides away from the first door panel 110, the slide rail 122, which is tilted in the extension direction, can compensate for the increase in the distance between the slide rail 122 and the bending area 21 through the sliding of the slider 123. This prevents the bending area 21 from being excessively stretched by the slide rail 122 due to the increase in the distance between the slide rail 122 and the bending area 21 after the slider 123 slides away from the first door panel 110, thereby preventing the stability of the connection between the bending area 21 and the slide rail 122 from being affected.

[0079] It is understood that in some embodiments, the surface of the slider 123 facing away from the slide rail 122 can be parallel to the extension direction of the slide rail 122, that is, the angle α between the surface of the slider 123 facing away from the slide rail 122 and the extension direction of the slide rail 122 is 0°. Similarly, the internal stress F can also push the slider 123 to slide relative to the slide rail 122, which helps to release the internal stress during the bending process of the bending zone 21.

[0080] The embodiment of the present application does not limit the manner in which the slider 123 and the slide rail 122 are slidably connected. Referring back to Figure 6 , the slide rail 122 includes a base 1221, a first stopper plate 1222, and a second stopper plate 1223. The base 1221 is connected to the body 121. A slide groove 1224 is provided at one end of the base 1221 facing away from the body 121. The direction in which the slide groove 1224 extends is perpendicular to the rotation axis n of the folding assembly, i.e., the direction in which the slide groove 1224 extends is in the x-direction.

[0081] One end of the first limiting plate 1222 and one end of the second limiting plate 1223 are both connected to the base 1221, and the other ends of the first limiting plate 1222 and the second limiting plate 1223 are both free ends. For ease of description, the free end of the first limiting plate 1222 is defined as the first free end 101, and the free end of the second limiting plate 1223 is defined as the second free end 102.

[0082] The first free end 101 and the second free end 102 are both located at the opening of the sliding groove 1224 , the slider 123 extends into the sliding groove 1224 and is slidably connected to the sliding groove 1224 , and the first free end 101 and the second free end 102 are both in contact with the slider 123 .

[0083] Because the slide groove 1224 extends along the x-direction, and the slider 123 extends into and slides in the slide groove 1224, the slider 123 can slide in the x-direction. Furthermore, because the first free end 101 and the second free end 102 are located at the opening of the slide groove 1224 and both abut against the slider 123, the first free end 101 and the second free end 102 can prevent the slider 123 from sliding out of the opening of the slide groove 1224. Thus, the slide rail 122 can constrain the slider 123 from sliding in the x-direction.

[0084] Furthermore, in some embodiments, to constrain the slider 123 from sliding along the x-direction, referring back to Figure 6 , the slide rail 122 further includes a guide post 1225 extending along the x-direction. The slider 123 is provided with a groove, and the guide post 1225 is positioned within the groove and slidably connected thereto. This slidable connection between the guide post 1225 and the groove further constrains the slider 123 from sliding along the x-direction.

[0085] The present embodiment does not limit the number of guide posts 1225. For example, the number of guide posts 1225 can be one, two, or more, and the slider 123 is also provided with a corresponding number of grooves, with one guide post 1225 slidably connected to one groove. It is understood that in some embodiments, the slide rail 122 may not be provided with guide posts 1225, and the first and second limit plates 1222 and 1223 may constrain the slider 123 from sliding along the x-direction.

[0086] In an embodiment where the second door panel 120 includes a stopper 125 (as shown in FIG7 ), the first limiting plate 1222 or the second limiting plate 1223 of the stopper 125 is connected to the stopper 125. In an embodiment where the second door panel 120 includes an elastic limiting portion 124, the elastic limiting portion 124 is located within the slide groove 1224. In this way, the elastic limiting portion 124 can avoid the bending area 21, thereby preventing friction between the elastic limiting portion 124 and the bending area 21.

[0087] In FIG7 , the first limiting plate 1222 and the base 1221 are connected as an integral part. The second limiting plate 1223 and the base 1221 are connected as an integral part. In this way, the assembly process can be saved during the production of the slide rail 122.

[0088] In other embodiments, the first limiting plate 1222 and the base 1221 may be connected by means of snap connection, welding, screw connection or bonding, etc. Similarly, the second limiting plate 1223 and the base 1221 may be connected by means of snap connection, welding, screw connection or bonding, etc.

[0089] In FIG7 , the base 1221 and the body 121 are connected as an integrally formed part, and the base 1221 and the body 121 do not need to be assembled separately, thereby reducing assembly costs. In other embodiments, the base 1221 and the body 121 can be independently provided, for example, the base 1221 and the body 121 are connected by means of clamping, welding, screwing, or bonding.

[0090] Figure 8a is a schematic structural diagram of another slider 123 and slide rail 122 provided in an embodiment of the present application. In Figure 8a, the first limit plate 1222 and the base 1221 are connected by a connector 126. Exemplarily, the connector 126 is a screw. In this way, the first limit plate 1222 and the base 1221 can be manufactured separately and then assembled through the connector 126, which can also limit the slider 123 from sliding along the x-direction. It is understandable that the connector 126 can be other structures such as a pin. In addition, in the process of assembling the slider 123 and the slide rail 122, the slider 123 can be placed in the slide groove 1224 first, and then the connector 126 is used to connect the first limit plate 1222 and the base 1221, which makes the assembly process simpler.

[0091] In FIG8 a , the first limiting plate 1222 and the second limiting plate 1223 have the same structure. Thus, the first limiting plate 1222 and the second limiting plate 1223 can be manufactured using the same process, thus saving manufacturing costs.

[0092] As described above, the first free end 101 and the second free end 102 are both in contact with the slider 123 . The embodiment of the present application does not limit the structures of the first free end 101 and the second free end 102 and the slider 123 .

[0093] 7 and 8a, the first free end 101 is a thin plate structure, and abuts against the surface of the slider 123 away from the base 1221. Similarly, the second free end 102 is also a thin plate structure, and abuts against the surface of the slider 123 away from the base 1221.

[0094] It is understandable that, in other embodiments, the abutment between the first free end 101 and the second free end 102 and the slider 123 may also be achieved in other ways.

[0095] Figure 8b is a schematic diagram of the structure of another slider 123 and slide rail 122 provided in an embodiment of the present application. Figure 8b differs from Figure 7 in the shapes of the slider 123, first free end 101, and second free end 102. In the example of Figure 8b, the first free end 101 has a receiving groove 103, the opening of which faces the second free end 102. A protrusion 104 is provided on the surface of the slider 123 facing the first free end 101. The protrusion 104 extends into the receiving groove 103 and abuts against the inner wall of the receiving groove 103.

[0096] In this way, when the slider 123 slides relative to the slide groove 1224, the receiving groove 103 can prevent the protrusion 104 from disengaging, thereby preventing the slider 123 from disengaging from the slide groove 1224, thereby constraining the sliding trajectory of the slider 123. In the example of Figure 8a, the structure of the second free end 102 is the same as that of the first free end 101, and will not be repeated here.

[0097] In FIG8b , the base 1221, the first limiting plate 1222, and the second limiting plate 1223 are connected as an integrally formed part. It is understood that in other embodiments, the first limiting plate 1222 and the base 1221 can be screwed, bonded, or welded. Similarly, the second limiting plate 1223 and the base 1221 can be screwed, bonded, or welded.

[0098] Figure 8c is a schematic structural diagram of another slider 123 and slide rail 122 provided in an embodiment of the present application. The difference between Figure 8c and Figure 7 is that the shapes of the slider 123, the first free end 101 and the second free end 102 are different. In Figure 8c, a receiving groove 105 is provided on the surface of the slider 123 facing the first free end 101, and a flange 106 is provided on the surface of the first free end 101 facing the slider 123. The flange 106 extends into the receiving groove 105 and abuts against the inner wall of the receiving groove 105. Similarly, the receiving groove 105 can prevent the flange 106 from detaching, thereby preventing the slider 123 from detaching from the slide groove 1224, thereby constraining the sliding trajectory of the slider 123. In the example of Figure 8c, the structure of the second free end 102 is the same as that of the first free end 101, and will not be repeated here.

[0099] Please refer to Figures 6, 7, 8a, 8b, and 8c. The second door panel 120 also includes a deformable layer 127, which is located between the slide rail 122 and the slider 123. The material of the deformable layer 127 includes glue. Because the deformable layer 127 is made of glue, the glue will deform under the action of an external force. For example, when the slider 123 applies a force to the deformable layer 127, the glue will deform. This deformation can cause the slide rail 122 and the slider 123 to slide relative to each other. In addition, the presence of the deformable layer 127 prevents direct contact between the slide rail 122 and the slider 123, thus avoiding the loud noise caused by direct contact between the rigid slide rail 122 and the slider 123. Furthermore, since the slide rail 122 and the slider 123 do not directly contact each other, the manufacturing precision of the slide rail 122 and the slider 123 can be lower, saving manufacturing costs.

[0100] For example, in some embodiments, the material of the deformable layer 127 may include optical adhesive, foam adhesive, hot melt adhesive, or the like.

[0101] In the embodiment where the slide rail 122 includes a slide groove 1224 , the deformable layer 127 is located in the slide groove 1224 , which can prevent the deformable layer 127 from affecting other components (eg, the bending region 21 shown in FIG. 5 ).

[0102] In other embodiments, a lubricating layer may be provided between the slide rail 122 and the slider 123 , wherein the lubricating layer may be made of a lubricant. The provision of the lubricating layer may reduce the noise generated by the direct sliding of the slide rail 122 and the slider 123 .

[0103] As shown in Figure 5, in this embodiment of the present application, the third door panel 130 and the second door panel 120 have the same structure (refer to the description of the second door panel 120 above). The third door panel 130 is slidably connected to the bending zone 21. The internal stress generated in the bending zone 21 during its folding and unfolding states is transferred to the third door panel 130 and released through sliding, effectively reducing delamination and cracking in the bending zone 21 caused by internal stress.

[0104] In addition, the third door panel 130 and the second door panel 120 have the same structure, and the third door panel 130 and the second door panel 120 can be formed using the same process, thereby reducing the manufacturing cost of the folding assembly 100 .

[0105] As can be seen in Figure 5, when the unfolded folding assembly 100 is folded, the third door panel 130 slides relative to the bending zone 21 in a direction away from the first door panel 110. That is, the sliding direction of the slider 123 on the third door panel 130 is opposite to that of the second door panel 120. This is because the direction of the internal stress in the portion connecting the bending zone 21 and the third door panel 130 is opposite to the direction of the internal stress in the portion connecting the bending zone 21 and the second door panel 120. This relieves the internal stress and prevents damage to the bending zone 21.

[0106] It is understood that in other embodiments, the structure of the third door panel 130 may differ from that of the second door panel 120. For example, the third door panel 130 and the bending zone 21 may not be connected in a sliding manner. However, due to the sliding connection between the second door panel 120 and the bending zone 21, the internal stress in the bending zone 21 between the second door panel 120 and the connecting portion can also be relieved, significantly alleviating cracking and delamination issues in the bending zone 21.

[0107] The above is only a specific embodiment of the present application, but the scope of protection of this application is not limited to this. Any changes or substitutions within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
