According to the specific scheme, a first door plate of the folding assembly comprises a sliding rail and a sliding block which are in sliding connection, and the sliding block can slide in the direction perpendicular to the rotating axis of the folding assembly. The sliding block is used for being connected with the bending area of the flexible screen.

Description

Technical Field

[0001] The embodiments of the present application relate to the field of folding structures, and in particular to a folding component and a terminal device. Background Art

[0002] With the continuous development of display technology, foldable devices (such as foldable mobile phones) have gradually become a development trend of future mobile electronic products. When the terminal device is unfolded, it can obtain a larger display area to improve the viewing effect. When the terminal device is folded, it can obtain a smaller volume, which is convenient for users to carry.

[0003] Typically, a terminal device includes a flexible screen and a folding assembly for supporting the flexible screen; the performance of the folding assembly directly affects the use of the terminal device. For example, if the performance of the folding assembly is poor, during use, the bending position of the flexible screen is prone to cracks after multiple bendings. Summary of the invention

[0004] The embodiments of the present application provide a folding component and a terminal device to improve the problem that the bending area of ​​the flexible screen is prone to cracks after multiple bending.

[0005] In order to achieve the above-mentioned purpose, this application adopts the following technical solution.

[0006] In the first aspect, the embodiment of the present application provides 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 rotatably connected to one side of the first door panel. The third door panel is rotatably connected to the side of the first door panel away from the second door panel. The second door panel includes a body and a slider. A slide rail is provided on the body, and the extension direction of the slide rail is perpendicular 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 sliding direction of the slider is perpendicular to the rotation axis of the folding assembly. When the surface of the slider away from the slide rail is connected to the bending area of ​​the flexible screen, when the bending area of ​​the flexible screen is bent, the bending area is deformed, and the internal stress after deformation is transmitted to the slider, and the internal stress has a component force in a direction perpendicular to the rotation axis, and the component force can push the slider to slide along the extension direction of the slide rail to release the internal stress. Avoiding the problem of internal stratification of the bending area of ​​the flexible screen due to the inability to release internal stress is also conducive to solving problems such as cracks caused by internal stress in the bending area after multiple bending. Similarly, when the bending zone of the flexible screen is unfolded, the deformation of the bending zone 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 zone and avoiding delamination problems in the bending zone.

[0007] In combination with the first aspect, in some achievable ways, the surface of the slider facing 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, the movement tendency 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 zone 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 zone is easy to determine, which can improve the assembly accuracy of the bending zone and the slider, and avoid problems such as arching of the flexible screen due to low assembly accuracy.

[0008] In combination with the first aspect, in some achievable methods, the angle between the surface of the slider away from the slide rail and the extension direction of the slide rail is 0° to 30°, and the opening of the angle is 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 tendency can cause the slider to be located at a position of the slide rail close to the first door panel. In this state, the bending area and the slider are connected to 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, and 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.

[0009] In combination with the first aspect, in some achievable embodiments, the second door panel further includes a deformation layer. The deformation layer is located between the slide rail and the slider; the material of the deformation layer includes glue. Since the material of the deformation layer includes glue, the glue will deform under the action of an external force, and when the slider applies a force to the deformation layer, the deformation will occur, and the deformation can cause the slide rail and the slider to slide relative to each other. In addition, the presence of the deformation layer prevents the slide rail from directly contacting the slider, thereby avoiding a loud sound caused by direct contact between a rigid slide rail and a rigid slider. Since the slide rail and the slider are not in direct contact, the manufacturing precision of the slide rail and the slider can be lower, saving manufacturing costs.

[0010] In combination with the first aspect, in some achievable manners, the second door panel further includes a lubricating layer. The lubricating layer is located between the slide rail and the slider; the material of the lubricating layer includes a lubricant. The provision of the lubricating layer including the lubricant can reduce the sound generated by the direct sliding of the slide rail and the slider.

[0011] In combination with the first aspect, in some achievable methods, 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 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 zone 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 body. In this case, connecting the bending zone and the slider is conducive to determining the relative position of the body and the bending zone, reducing the dislocation of the body and the bending zone, and avoiding the arching of the flexible screen.

[0012] In combination with the first aspect, in some achievable ways, the second door panel further includes a stopper. The stopper is located on the side of the slider away from the elastic limiting portion, and the stopper is connected to the slide rail or the body. When the slider slides relative to the slide rail until it abuts against the stopper, the elastic limiting portion is in a compressed state or a free state. If the elastic limiting portion is in a compressed state, the elastic limiting portion has a tendency to make the slider slide relative to the slide rail in a direction away from the elastic limiting portion. Because the side of the slider away from the elastic limiting portion abuts against the stopper, the stopper prevents the slider from sliding in a direction away from the elastic limiting portion. The elastic limiting portion and the stopper have the function of positioning the slider on the slide rail. In this state, the slider and the bending zone are connected to avoid dislocation between the slider and the bending zone, and to avoid arching of the bending zone. Similarly, if the elastic limiting portion is in a free state, the elastic limiting portion cannot drive the slider to slide in the direction toward the elastic limiting portion. Similarly, the elastic limiting portion and the stopper have the function of positioning the slider on the slide rail. Connecting the slider and the bending zone in this state can also prevent the slider and the bending zone from being dislocated and the bending zone from being arched.

[0013] In combination with the first aspect, in some achievable manners, the second door panel further comprises: an adhesive layer. The adhesive layer is connected to the surface of the slider away from the slide rail. In this way, the end of the slider away from the slide rail can be connected to the bending area of ​​the flexible screen through the adhesive layer.

[0014] In conjunction with the first aspect, in some achievable manners, the vertical projection of the adhesive layer on the slider is located inside the slider, so that the adhesive layer can be prevented from overflowing the slider, for example, from overflowing to the connection between the slide rail and the slider, affecting the smoothness of the sliding of the slider and the slide rail.

[0015] In combination with the first aspect, in some achievable ways, the slide rail includes a base, a first limit plate and a second limit plate. The base is connected to the body, and a slide groove is provided on the surface of the base away from the body, and the extension direction of the slide groove is perpendicular to the rotation axis of the folding component. One end of the first limit plate and one end of the second limit plate are both connected to the base, and the other end of the first limit plate and the other end of the second limit plate are both free ends and are located at the opening of the slide groove. The slider extends into the slide groove and is slidably connected to the slide groove, and the free ends of the first limit plate and the second limit plate are both abutted against the slider. Because the extension direction of the slide groove is perpendicular to the rotation axis of the folding component, and the slider extends into the slide groove and is slidably connected to the slide groove, the movement direction of the slider is perpendicular to the rotation axis of the folding component. Because the first free end and the second free end are located at the opening of the slide groove and are both abutted against the slider, the first free end and the second free end can limit the slider from sliding off the opening of the slide groove, thereby, the slide rail can constrain the movement direction of the slider to be perpendicular to the rotation axis of the folding component.

[0016] In combination with the first aspect, in some achievable manners, the base, the first limit plate and the second limit plate are connected to form an integrally formed part. In this way, the base, the first limit plate and the second limit plate can be formed at one time, simplifying the forming process of the slide rail.

[0017] In conjunction with the first aspect, in some achievable manners, the slide rail further comprises a connecting piece, and the first limit plate and the base are connected via the connecting piece. Thus, during the process of assembling 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 are connected by the connecting piece, which simplifies the assembly process.

[0018] In combination with the first aspect, in some practicable manners, 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.

[0019] In combination with the first aspect, in some achievable embodiments, the second door panel includes a plurality of the sliders, and the main body is provided with a plurality of the slide rails. The plurality of slide rails are arranged at intervals along the axis of rotation of the folding component, and one slide rail is connected to one slider. Thus, when the slider of the second door panel is connected to the bending zone, each part of the bending zone along the axis of rotation of the folding component has internal stress during the bending process of the bending zone. In this way, a plurality of slide rails and a plurality of sliders are arranged along the axis of rotation of the folding component, so that the internal stress of multiple areas of the bending zone along the axis of rotation of the folding component is released, further improving the crack and delamination problems caused by internal stress.

[0020] In combination with the first aspect, in some achievable ways, when the folding assembly is in the unfolded state, the slider is located at one end of the slide rail facing the second door panel. In this way, the slider of the second door panel can only move along the direction of the slide rail 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 direction of the slide rail away from the first door panel, and the sliding direction is the same as the direction of the force exerted by the bending zone on the slider when the bending zone of the flexible screen is bent. This is conducive to the release of internal stress when the bending zone is bent.

[0021] In combination with the first aspect, in some achievable 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.

[0022] In combination with the first aspect, in some achievable manners, 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.

[0023] In combination with the first aspect, in some achievable manners, the third 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 body or the slide rail.

[0024] In combination with the first aspect, in some achievable manners, the third door panel further comprises: a stopper. The stopper is located at a side of the slider away from the elastic limiting portion, and the stopper is connected to the slide rail or the body. When the slider slides relative to the slide rail until it abuts against the stopper, the elastic limiting portion is in a compressed state or a free state.

[0025] 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 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 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 the slider slides relative to the slide rail together, 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

[0037] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings.

[0038] In the following, the terms "first", "second", etc. are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "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.

[0039] In addition, in the present 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 the changes in the orientation of the components in the drawings.

[0040] 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 the mobile phone as an example of the terminal device.

[0041] Figure 1 FIG. 1 is a schematic diagram of the structure of a terminal device 10. Figure 1 The terminal device 10 includes a flexible screen 20 and a folding assembly 100. The flexible screen 20 is connected to the folding assembly 100, and the folding assembly 100 is used to support the flexible screen 20.

[0042] Wherein, the flexible screen 20 is used to display images. In some embodiments of the present application, the flexible screen 20 is a multilayer structure. The flexible screen 20, for example, includes 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. In some other embodiments of the present application, the flexible screen 20 may be an active matrix organic light emitting diode (AMOLED) display.

[0043] Figure 2 for Figure 1 A magnified schematic diagram of the center. Figure 2 , the folding assembly 100 is connected to the flexible screen 20. The flexible screen 20 includes a bending area 21 and a non-bending area 22 connected to each other, and the bending area 21 and the non-bending area 22 are both connected to one side of the folding assembly 100.

[0044] 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 rotatably connected to two opposite sides of the first door panel 110, respectively. 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 (such as Figure 1 When the folding assembly 100 rotates from the unfolded state to the folded state, the second door panel 120 and the third door panel 130 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 form a door as shown in FIG. Figure 2 The arc-shaped space C shown accommodates the bending area 21 of the flexible screen 20 . Figure 3 It is a structural diagram of the rotating shaft assembly 01 and the display screen 02 in the related art. Figure 3 The shaft assembly 01 includes a middle plate 03 and two rotating plates 04, and the two rotating plates 04 are respectively rotatably connected to two opposite sides of the middle plate 03. The two rotating plates 04 are connected to the display screen 02 through an adhesive member 05.

[0045] When the shaft assembly 01 is in the Figure 3 In the folded state shown, the display screen 02 is also in a bent state, and the display screens 02 are pressed against each other, for example, Figure 3 The right part of the display screen 02 will apply force f to the left part. Because the display screen 02 is a multi-layer structure, after the display screen 02 is folded and unfolded many times, the multi-layer display screen 02 will have problems such as delamination and cracks.

[0046] 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.

[0047] like Figure 2 As shown, the second door panel 120 includes a body 121 and a slider 123. The body 121 is provided with a slide rail 122. The extension direction of the slide rail 122 is parallel to the rotation axis n (eg, Figure 1 The slider 123 is movably connected to the slide rail 122. For example, the slider 123 is slidably connected to the slide rail 122.

[0048] 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 zone 21 of the flexible screen 20, when the bending zone 21 of the flexible screen 20 is bent around the rotation axis n, the bending zone 21 is deformed, and the deformed internal stress F is transmitted to the slider 123, so that the slider 123 and the bending zone 21 slide along the extension direction of the slide rail 122 together, and the internal stress F is released. It effectively improves the problem of internal stratification of the bending zone 21 caused by the internal stress F of the bending zone 21, and is also conducive to solving problems such as cracks caused by internal stress of the bending zone 21 after multiple bending. Similarly, when the bending zone 21 of the flexible screen 20 is unfolded, the deformation of the bending zone 21 generates a force in the opposite direction of the aforementioned internal stress F, which causes the slider 123 to slide back and reset, which also achieves the problem of releasing internal stress, reducing cracks and stratification of the bending zone 21.

[0049] In addition, during the bending process of the bending zone 21, the internal stress F is not enough to push the entire bending zone 21 to move, so the distance that the bending zone 21 and the slider 123 move relative to the body 121 is small, and the movement distance has little effect on the position of the entire bending zone 21. For example, the movement distance cannot cause the connection between the bending zone 21 and the non-bending zone 22 to be displaced relative to the entire second door panel 120, and has little effect 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 through the slider 123, and the sliding distance of the slider 123 hardly affects the position and flatness of the bending zone 21, thereby avoiding the problem of arching at the connection between the bending zone 21 and the non-bending zone 22.

[0050] In some embodiments, the folding assembly 100 further includes a middle frame 31, and the first door panel 110, the second door panel 120, and the third door panel 130 are all rotatably connected to the middle frame 31. Exemplarily, the middle frame 31 includes a bearing plate and a frame around the bearing plate. The middle frame 31 is connected to the non-bending area 22 of the flexible screen 20. For example, the middle frame 31 and the non-bending area 22 are bonded.

[0051] As mentioned above, the second door panel 120 is rotatably connected to the first door panel 110. The embodiment of the present application does not limit the manner in which the second door panel 120 is rotatably connected to the first door panel 110. In some embodiments, the second door panel 120 is hinged to the first door panel 110. In other embodiments, the first door panel 110 is rotatably connected to the middle frame 31, and the second door panel 120 is rotatably connected to the middle frame 31, so that the second door panel 120 and the first door panel 110 are rotatably connected.

[0052] 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, and the x direction and the z direction describe each other. It can be understood that during the unfolding or folding process of the folding assembly 100, the extension direction x direction of the slide rail 122 is constantly changing, but is perpendicular to the z direction.

[0053] Figure 4 This is a schematic structural diagram of the folding assembly 100 provided in an embodiment of the present application in an unfolded state. Figure 4 In the embodiment, the second door panel 120 has a plurality of sliders 123, and a plurality of slide rails 122 are arranged on the body 121. The plurality of slide rails 122 are arranged at intervals along the z direction, and the plurality of slide rails 122 are connected to the body 121, and one slide rail 122 is connected to one slider 123. Figure 2 During the bending process, each part of the bending zone 21 along the z direction has an internal stress F (as shown in FIG. Figure 2 As shown in FIG. 1 , multiple slide rails 122 and multiple sliders 123 are arranged at intervals along the z direction, so that the internal stress of multiple regions of the bending area 21 along the z direction is released, further improving the crack and delamination problems caused by the internal stress.

[0054] The embodiment of the present application does not limit the number of the slide rails 122 on the second door panel 120 . For example, the number of the slide rails 122 may be one, two, three or more.

[0055] In the embodiment where the second door panel 120 includes a plurality of slide rails 122, the embodiment of the present application does not limit the positional relationship of the plurality of slide rails 122 in the x direction. For example, Figure 4 In the embodiment, the two opposite ends of the plurality of slide rails 122 along the x direction are aligned. In other embodiments, the two opposite ends of the plurality of slide rails 122 along the x direction may not be aligned, for example, some of the slide rails 122 are closer to the first door panel 110 than the other slide rails 122.

[0056] Figure 4 In the embodiment, 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. In this way, the slider 123 of the second door panel 120 can only move in the direction away from the first door panel 110 along the slide rail 122 (such as Figure 4 The sliding block 123 moves in the direction of the arrow on the middle sliding block 123. That is, when the folding assembly 100 rotates from the unfolded state to the folded state, the sliding block 123 can only slide along the direction of the sliding rail 122 away from the first door panel 110, and the sliding direction is the same as the direction of the force exerted by the bending zone 21 on the sliding block 123 when the bending zone 21 is bent. It is beneficial to the release of internal stress when the bending zone 21 is bent. It can be understood that the aforementioned sliding direction is the same as the direction of the force exerted by the bending zone 21 on the sliding block 123 and is not limited to the angle between the two directions being 0°. For example, the angle between the two directions can be 0° to 90°; for example, it can be 0°, 10°, 20°, 30°, 40°, 50° or 90°, etc.

[0057] In some embodiments, the folding assembly 100 is in Figure 2In the folded state shown in , the slider 123 is located at the end of the slide rail 122 away from the first door panel 110. Similarly, when the folding assembly 100 rotates 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, and the 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 is bent, which is conducive to the release of internal stress when the bending zone 21 is bent.

[0058] 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.

[0059] Figure 5 This is a schematic diagram of the exploded structure of the folding assembly 100 and the flexible screen 20 provided in the embodiment of the present application. Figure 5 It is shown in Figure 4 Schematic diagram of the folding assembly 100 on the DD section plane. Figure 5 In the embodiment, the folding assembly 100 and the flexible screen 20 are both in an unfolded state.

[0060] Figure 5 In the embodiment, the bending area 21 of the flexible screen 20 and the body 121 of the second door panel 120 are connected by the adhesive layer 201. In other words, the second door panel 120 further includes an adhesive layer 201, and the adhesive layer 201 is connected to the surface of the slider 123 away from the slide rail 122, and the slider 123 is connected to the bending area 21 of the flexible screen 20 through 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 transmitted to the slider 123 through the adhesive layer 201 and released.

[0061] In some embodiments, the vertical projection of the adhesive layer 201 on the slider 123 is located inside the slider 123. In this way, the adhesive layer 201 can be prevented from overflowing the slider 123, for example, from overflowing to the connection between the slide rail 122 and the slider 123, which would affect the smoothness of the sliding of the slider 123 and the slide rail 122. It is understandable that if the fluidity of the adhesive layer 201 is poor, the vertical projection of the adhesive layer 201 on the slider 123 can be partially located outside the slider 123, because the possibility of flowing to other areas (for example, the end surface of the slider 123 facing the slide rail 122) is small due to the poor fluidity, and the impact on other areas is small.

[0062] 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.

[0063] In some embodiments, the adhesive layer 201 and the slider 123 may be connected first, and then the bending area 21 and the surface of the adhesive layer 201 away from the slider 123 may be connected. Alternatively, in other embodiments, the adhesive layer 201 and the bending area 21 may be connected first, and then the slider 123 and the surface of the adhesive layer 201 away from the bending area 21 may be connected. For the above two connection processes, to determine the relative position of the 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 body 121. Because the slider 123 will slide 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, the position of the slider 123 on the body 121 is positioned, and then the slider 123, the adhesive layer 201 and the bending area 21 are connected so that the body 121 and the bending area 21 have a determined positional relationship.

[0064] Figure 6 This is a schematic diagram of the structure of a slider 123 and a slide rail 122 provided in an embodiment of the present application. Figure 6 The second door panel 120 further 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 the extension direction x direction thereof. Since 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 movement direction 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.

[0065] The extension direction of the elastic limiting portion 124 is the direction in which the elastic limiting portion 124 is deformed after a tensile force or pressure is applied to the extension direction, and the elastic limiting portion 124 is restored after the tensile force or pressure is removed. If the elastic limiting portion 124 can be deformed in multiple directions under tensile force or pressure, any direction can be designated as the extension direction.

[0066] Please return to Figure 5 , when the folding assembly 100 is in Figure 5In the unfolded state shown, the elastic property of the elastic limiting portion 124 makes the slider 123 stationary relative to the slide rail 122. For example, the elastic limiting portion 124 will push or pull the slider 123 until the force of the elastic limiting portion 124 on the slider 123 prevents the slider 123 from moving relative to each other. 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 limiting portion 124 can convert the external force into elastic potential energy, and the elastic limiting portion 124 can prevent the slider 123 from sliding arbitrarily 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, and reducing the dislocation of 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 is connected to the slider 123, and the bending area 21 is connected to the slider 123 through 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 have a certain positional relationship. Increasing the assembly accuracy of the flexible screen 20 and the folding assembly 100 can prevent the bending area 21 from arching due to connection misalignment.

[0067] In addition, when the folding assembly 100 is folded from the unfolded state to the folded state, the slider 123 slides relative to the slide rail 122, and the slider 123 pushes the elastic limiter 124, so that the elastic limiter 124 stores elastic potential energy. In the process of unfolding the folding assembly 100 from the folded state to the unfolded state, the elastic potential energy can push the slider 123 to slide relative to the slide rail 122, so that the slider 123 drives the bending area 21 to return to the position in the unfolded state.

[0068] The 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 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 sheet or a foam layer.

[0069] Figure 7 for Figure 6 Schematic diagram of the structure of the N surface. Figure 7 The second door panel 120 further includes a stopper 125, which is located on the side of the slider 123 away from the elastic limiting portion 124, and 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 against the stopper 125 (such as Figure 7 As shown), the elastic limiting portion 124 is in a compressed state or a free state.

[0070] In some embodiments, when the slider 123 slides to abut against the stopper 125, the elastic limiter 124 is in a compressed state, and the elastic limiter 124 has a tendency to make the slider 123 slide relative to the slide rail 122 in a direction away from the elastic limiter 124. Because the side of the slider 123 away from the elastic limiter 124 abuts against the stopper 125, when the elastic limiter 124 applies elastic force to the slider 123, the stopper 125 prevents the slider 123 from sliding in a direction away from the elastic limiter 124. The elastic limiter 124 and the stopper 125 have the function of positioning the slider 123 on the slide rail 122, thereby positioning the slider 123 on the body 121. When the folding assembly 100 is in Figure 5 When the unfolded state shown is to be connected to the bending zone 21, without being affected by external force, the elastic limiting portion 124 and the stop portion 125 assist each other to determine the relative position 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.

[0071] In other embodiments, when the slider 123 slides to abut against the stopper 125, the elastic limiter 124 is in a free state. The elastic limiter 124 cannot drive the slider 123 to move in a direction away from the stopper 125. Similarly, without the action of external force, the elastic limiter 124 and the stopper 125 have the function of positioning the slider 123 on the slide rail 122, thereby positioning the slider 123 on the body 121. In this state, the slider 123 and the bending zone 21 are connected, which can also prevent the slider 123 and the bending zone 21 from being dislocated and prevent the bending zone 21 from arching.

[0072] The embodiment of the present application does not limit the structure of the stopper 125 . When the stopper 125 abuts against the slide rail 122 , the stopper 125 can limit the slider 123 from continuing to move in the direction toward the stopper 125 .

[0073] As mentioned above, the stopper 125 is connected to the slide rail 122 or the body 121. In the embodiment where the stopper 125 is connected to the slide rail 122, the connection method of the stopper 125 and the slide rail 122 can be, for example, a snap connection, bonding, or screw connection, or the stopper 125 and the slide rail 122 are connected as an integral part. Similarly, in the embodiment where the stopper 125 is connected to the body 121, the connection method of the stopper 125 and the body 121 can be, for example, a snap connection, bonding, or screw connection, or the stopper 125 and the body 121 are connected as an integral part.

[0074] Please refer again Figure 7 , Figure 7In the example, the surface of the slider 123 away from the slide rail 122 is not parallel to the extension direction of the slide rail 122. As mentioned above, the internal stress F after the deformation of the bending area 21 is transmitted to the slider 123, and the internal stress F causes the slider 123 to move along the extension direction x of the slide rail 122. Since the bending area 21 is connected to the surface of the slider 123 away from the slide rail 122, the movement trajectory of the bending area 21 when bending is an arc trajectory, and the internal stress F generated by the deformation of the bending area 21 is not parallel to the surface of the slider 123 away from the slide rail 122. Compared with the example in which the surface of the slider 123 away from the slide rail 122 is parallel to the x direction, the surface of the slider 123 away from the slide rail 122 is also not parallel to the x direction, and the component force Fx of the internal stress F in the x direction is relatively larger, which can better push the slider 123 to move in the x direction, so that the internal stress F is better released.

[0075] Also, please return to Figure 5 In the process of assembling 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 moved toward Figure 5 That is, the slider 123 is located above the 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 lower end of the slide rail 122. It is beneficial to locate the position of the slider 123 that is not connected to the bending zone 21. After positioning the slider 123 and then connecting the bending zone 21 and the slider 123, it is beneficial to determine the relative position of the body 121 and the bending zone 21, and reduce the dislocation between the body 121 and the bending zone 21.

[0076] Figure 7 In the embodiment, the angle α between the surface of the slider 123 away from the slide rail 122 and the extension direction of the slide rail 122 is 0° to 30° (excluding 0°), and the opening of the angle α is away from the first door panel 110. For example, the angle α can be 1°, 5°, 10°, 12°, 15°, 20°, 25°, 28°, 30°, etc. Since the opening of the angle α is away from the first door panel 110, when the second door panel 120 rotates around the rotation axis n (such as Figure 4When the slider 123 rotates (as shown in the figure), the bending zone 21 rotates relative to the surface of the slider 123 away from the slide rail 122, and the bending zone 21 pulls the slider 123 toward the bending zone 21. Because the opening of the angle α is away from the first door panel 110, the slider 123 is closer to the bending zone 21 at the end of the slide rail 122 away from the first door panel 110 than at the end of the slider 123 where the slide rail 122 is close to the first door panel 110. In this way, during the process of the slide rail 122 sliding away from the first door panel 110, the slide rail 122 inclined in the extension direction can compensate for the increase in the distance between the slide rail 122 and the bending zone 21 through the sliding of the slider 123. It is prevented that the distance between the slide rail 122 and the bending zone 21 increases after the slider 123 slides away from the first door panel 110, resulting in the bending zone 21 being over-stretched by the slide rail 122, which affects the connection stability between the bending zone 21 and the slide rail 122.

[0077] It is understandable that, in some embodiments, the surface of the slider 123 away from the slide rail 122 may be parallel to the extension direction of the slide rail 122, that is, the angle α between the surface of the slider 123 away from the slide rail 122 and the extension direction of the slide rail 122 is 0°. Similarly, the internal stress F may also push the slider 123 to slide relative to the slide rail 122, which is conducive to releasing the internal stress of the bending zone 21 during the bending process.

[0078] The embodiment of the present application does not limit the manner in which the slider 123 and the slide rail 122 are slidably connected. Figure 6 , Figure 6 In the embodiment, the slide rail 122 includes a base 1221, a first limit plate 1222 and a second limit plate 1223. The base 1221 is connected to the body 121. A slide groove 1224 is provided at one end of the base 1221 away from the body 121, and the extension direction of the slide groove 1224 is perpendicular to the rotation axis n of the folding assembly, that is, the extension direction of the slide groove 1224 is the x direction.

[0079] 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 end of the first limiting plate 1222 and the other end of 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.

[0080] The first free end 101 and the second free end 102 are both located at the opening of the slide groove 1224 , the slider 123 extends into the slide groove 1224 and is slidably connected to the slide groove 1224 , and the first free end 101 and the second free end 102 are both in contact with the slider 123 .

[0081] Because the slide groove 1224 extends along the x-direction, and the slider 123 extends into the slide groove 1224 and is slidably connected to the slide groove 1224, the slider 123 can slide in the x-direction. 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 restrict the slider 123 from sliding off the opening of the slide groove 1224, and thus, the slide rail 122 can restrict the slider 123 from sliding along the x-direction.

[0082] Further, in some embodiments, in order to constrain the slider 123 to slide along the x direction. Figure 6 In some embodiments, the slide rail 122 further includes a guide post 1225, which extends along the x-direction. The slider 123 is provided with a groove, and the guide post 1225 is located in the groove and is slidably connected to the groove. In this way, the slider 123 can be further constrained to slide along the x-direction through the sliding connection between the guide post 1225 and the groove.

[0083] The embodiment of the present application does not limit the number of guide posts 1225. For example, the number of guide posts 1225 may be one, two, or more, and the slider 123 is also provided with a corresponding number of grooves, and one guide post 1225 is slidably connected to one groove. It is understood that in some embodiments, the slide rail 122 may not be provided with a guide post 1225, and the first limit plate 1222 and the second limit plate 1223 may constrain the slider 123 to slide along the x direction.

[0084] The second door panel 120 includes a stopper 125 (such as Figure 7 In the embodiment shown in FIG. 1 , the first limiting plate 1222 or the second limiting plate 1223 of the stopper 125 is connected to the stopper 125. In the embodiment in which the second door panel 120 includes an elastic limiting portion 124, the elastic limiting portion 124 is located in the slide groove 1224, so that the elastic limiting portion 124 can avoid the bending area 21 to avoid friction between the elastic limiting portion 124 and the bending area 21.

[0085] Figure 7 In the embodiment, the first limiting plate 1222 and the base 1221 are connected as an integrally formed part. The second limiting plate 1223 and the base 1221 are connected as an integrally formed part. In this way, in the process of manufacturing the slide rail 122, the assembly process can be saved.

[0086] In other embodiments, the first limiting plate 1222 and the base 1221 may be connected by means of clamping, welding, screwing or bonding. Similarly, the second limiting plate 1223 and the base 1221 may be connected by means of clamping, welding, screwing or bonding.

[0087] Figure 7In the embodiment, 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 the assembly cost. 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.

[0088] Figure 8a A schematic diagram of the structure of another slider 123 and a slide rail 122 provided in an embodiment of the present application. Figure 8a In the figure, the first limit plate 1222 and the base 1221 are connected by a connecting member 126. Exemplarily, the connecting member 126 is a screw. In this way, the first limit plate 1222 and the base 1221 can be manufactured separately and then assembled by the connecting member 126, which can also limit the sliding of the slider 123 along the x direction. It can be understood that the connecting member 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 connecting member 126 is used to connect the first limit plate 1222 and the base 1221, and the assembly process is simpler.

[0089] Figure 8a In the embodiment, the first limiting plate 1222 and the second limiting plate 1223 have the same structure, so the first limiting plate 1222 and the second limiting plate 1223 can be manufactured by the same process, thus saving manufacturing costs.

[0090] As described above, the first free end 101 and the second free end 102 are both in contact with the slider 123 , and 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 .

[0091] Figure 7 and Figure 8a In the embodiment, the first free end 101 is a thin plate structure, and the first free end 101 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 the second free end 102 abuts against the surface of the slider 123 away from the base 1221.

[0092] It can be understood that, in other embodiments, the abutment between the first free end 101 and the second free end 102 and the slider 123 can also be achieved in other ways.

[0093] Figure 8b A schematic diagram of the structure of another slider 123 and a slide rail 122 provided in an embodiment of the present application. Figure 8b and Figure 7 The difference lies in the different shapes of the slider 123, the first free end 101 and the second free end 102. Figure 8bIn the example, the first free end 101 has a receiving groove 103, and the opening of the receiving groove 103 faces the second free end 102. The surface of the slider 123 facing the first free end 101 is provided with a convex portion 104, which extends into the receiving groove 103 and abuts against the inner wall of the receiving groove 103.

[0094] In this way, when the slider 123 slides relative to the slide groove 1224 , the receiving groove 103 can prevent the protrusion 104 from being separated, thereby preventing the slider 123 from being separated from the slide groove 1224 , thereby constraining the sliding trajectory of the slider 123 . Figure 8a In the example, the structure of the second free end 102 is the same as that of the first free end 101, and will not be described in detail here.

[0095] Figure 8b In the embodiment, 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.

[0096] Figure 8c A schematic diagram of the structure of another slider 123 and a slide rail 122 provided in an embodiment of the present application. Figure 8c and Figure 7 The difference lies in the different shapes of the slider 123, the first free end 101 and the second free end 102. Figure 8c In the embodiment, 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 being disengaged, thereby preventing the slider 123 from being disengaged from the slide groove 1224, thereby constraining the sliding track of the slider 123. Figure 8c In the example, the structure of the second free end 102 is the same as that of the first free end 101, and will not be described in detail here.

[0097] Please also read Figure 6 , Figure 7 , Figure 8a , Figure 8b as well as Figure 8cThe second door panel 120 also includes a deformation layer 127, and the deformation layer 127 is located between the slide rail 122 and the slider 123. The material of the deformation layer 127 includes glue. Since the material of the deformation layer 127 includes glue, the glue will deform under the action of external force. For example, the slider 123 deforms after applying force to the deformation layer 127, and the deformation can make the slide rail 122 and the slider 123 slide relative to each other. In addition, the existence of the deformation layer 127 prevents the slide rail 122 from directly contacting the slider 123, avoiding the rigid slide rail 122 and the rigid slider 123 from directly contacting each other, resulting in loud noise. Furthermore, the slide rail 122 and the slider 123 are not in direct contact, and the manufacturing precision of the slide rail 122 and the slider 123 can be lower, saving manufacturing costs.

[0098] For example, in some embodiments, the material of the deformation layer 127 may include optical adhesive, foam adhesive, hot melt adhesive, etc.

[0099] In the embodiment where the slide rail 122 includes a slide groove 1224, the deformable layer 127 is located in the slide groove 1224, so as to prevent the deformable layer 127 from affecting other components (such as Figure 5 The influence of the bending zone 21) shown in FIG.

[0100] In some other embodiments, a lubricating layer may be provided between the slide rail 122 and the slider 123 , and the material of the lubricating layer includes a lubricant. The provision of the lubricating layer may reduce the sound generated by the direct sliding of the slide rail 122 and the slider 123 .

[0101] like Figure 5 As shown, in the embodiment of the present application, the third door panel 130 has the same structure as the second door panel 120, please refer to the description of the second door panel 120. The third door panel 130 is slidably connected to the bending area 21. The internal stress generated by the bending area 21 in the bending and unfolding states is transmitted to the third door panel 130 and released by sliding, which can effectively improve the delamination and cracks of the bending area 21 caused by the internal stress.

[0102] 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 by the same process, thereby reducing the manufacturing cost of the folding assembly 100 .

[0103] Figure 5 It can be seen from the figure that when the folding assembly 100 in the unfolded state 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 the sliding direction on the second door panel 120. Because the direction of the internal stress of the portion where the bending zone 21 and the third door panel 130 are connected is opposite to the direction of the internal stress of the portion where the bending zone 21 and the second door panel 120 are connected. In this way, the internal stress can be released to avoid damage to the bending zone 21 caused by the internal stress.

[0104] It is understood that in other embodiments, the structure of the third door panel 130 may be different 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. Since the second door panel 120 and the bending zone 21 are connected in a sliding manner, the internal stress of the second door panel 120 and the connected part of the bending zone 21 can also be released, which significantly improves the crack and delamination problems of the bending zone 21.

[0105] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
