[0052] The terms used in the implementation part of the present application are only used to explain the specific embodiments of the present application, and are not intended to limit the present application. The embodiments of the present application will be described in detail below with reference to the drawings.
[0053] First, the application scenarios of the embodiments of the present application will be described below with reference to the drawings.
[0054] Figure 1 is a schematic diagram of a foldable electronic device. The foldable electronic device is an electronic device whose display screen can realize 0-degree to 360-degree folding. The foldable electronic device generally includes: a first body 101, a second body 103 rotatably connected to the first body 101 through a hinge assembly 102, and a display screen 104 disposed on one side of the first body 101 and the second body 103. Based on the above structure, as shown in A in Figure 1 , the foldable electronic device can be set as an inner folding foldable electronic device, as shown in B in Figure 1 , the foldable electronic device can be set as an outer folding foldable electronic device, and as shown in C in Figure 1 , the foldable electronic device can be set as an up-down folding foldable electronic device.
[0055] Here, it should be noted that, Figure 1 The dashed line in FIG. 1 indicates the position of the hinge assembly 102 of the foldable electronic device, which is not visible due to being blocked by the display screen 104.
[0056] The embodiments of the present application are applicable to foldable electronic devices in which the surfaces of the display screen 104 used for displaying images are close to each other when the foldable electronic device is in a folded state, such as an inward folding foldable electronic device and an up-down folding foldable electronic device. In the following embodiments, the inward folding foldable electronic device is taken as an example.
[0057] Figure 2 is a schematic diagram of components of a foldable electronic device. As shown in Figure 2 The display screen 104 of the foldable electronic device includes a first fixed portion 1041, a second fixed portion 1042, and a curved portion 1043. The first fixed portion 1041 is configured to be fixedly connected to the first body 101, the second fixed portion 1042 is configured to be fixedly connected to the second body 103, and the curved portion 1043 is configured to be relatively displaced with respect to the first fixed portion 1041, the second fixed portion 1042, and the hinge assembly 102, so as to change in response to the folding state and the unfolded state of the display screen 104.
[0058] The display screen 104 includes a display module and a transparent cover plate. The display module is capable of displaying images, videos, and the like. The display module can be a liquid crystal display (LCD), an organic light-emitting diode (OLED), an active-matrix organic light-emitting diode (AMOLED), a flexible light-emitting diode (FLED), a Miniled, a MicroLed, a Micro-oLed, a quantum dot light-emitting diode (QLED), or the like. The transparent cover plate covers the outside of the display module and serves to protect the display module. The transparent cover plate can be a glass cover plate, or can be another transparent material capable of serving the protection function. The display screen 104 can also have a touch function, i.e., the display screen 104 can be a touch screen. The side surface of the display screen 104 used for displaying images is the side surface of the transparent cover plate facing away from the display module.
[0059] Further as shown in Figure 2As shown, the foldable electronic device further comprises a frame 105, which is fixedly connected with the first body 101 and the second body 103. After the first fixed part 1041 is arranged on the first body 101 and the second fixed part 1042 is arranged on the second body 103, the frame 105, the first body 101 and the second body 103 can play a limiting and supporting role on the display screen 104.
[0060] It should be noted that the frame 105 can be integrally formed with the first body 101 and the second body 103, so that the first body 101, the second body 103 and the frame 105 jointly serve as the middle frame of the foldable electronic device. Alternatively, the frame 105 can be fixedly connected with the first body 101 and the second body 103 as part of the middle frame and the shell of the foldable electronic device. The connection order and connection relationship of the above-mentioned components are not limited in the present application.
[0061] Figure 3 is a schematic view of a hinge assembly of the foldable electronic device. As shown, Figure 3 The hinge assembly 102 can comprise a swing arm 1021, a wedge-shaped block 1022, a door plate 1023, a cover plate 1024, a base 1025 and a shaft cover 1026. The shaft cover 1026 is arranged opposite to the curved part 1043. The cover plate 1024 is located between the shaft cover 1026 and the curved part 1043 and is fixedly connected with the shaft cover 1026 to form a cavity. At least a part of the base 1025 is located inside the cavity. The combination of the cover plate 1024, the base 1025 and the shaft cover 1026 serves as the base body 1020 of the hinge assembly 102, so as to facilitate the arrangement of other components. The swing arm 1021 is integrally formed with the wedge-shaped block 1022. A virtual tongue (as shown in M1 area of Figure 3 The virtual tongue is also connected with the virtual shaft of the door plate 1023. In this connection mode, the wedge-shaped block 1022 is fixedly connected with the frame 105. Since the display screen 104 is also fixedly connected with the frame 105, the displacement of the wedge-shaped block 1022, the swing arm 1021 and the door plate 1023 relative to the base body 1020 can make the frame 105 and the display screen 104 change from the folded state to the unfolded state.
[0062] It should be noted that, Figure 3 Only a partial schematic view of the hinge assembly 102 is shown, i.e. one side end of the hinge assembly 102 is a region where the end face of the hinge assembly 102 extends a certain distance along the axial direction of the hinge assembly. The actual hinge assembly 102 further comprises another part which is not shown in the schematic view and is axially symmetrical to the part shown in the schematic view. Figure 3 The actual expressions of the present application are expressed based on the overall arrangement of the hinge assembly 102.
[0063] Figure 4 is a schematic diagram of a falling state of a foldable electronic device. As shown in Figure 4 , taking the foldable electronic device in the folded state as an example, due to the effect of inertia, the axial side angle of the foldable electronic device usually falls to the ground first, that is, the axial side angle of the foldable electronic device falls, and in the process of the axial side angle falling, the position of the axial side angle contacting the ground does not change, and the foldable electronic device will be forced to unfold, at this time, the frame 105 and the display screen 104 will produce displacement close to the hinge assembly 102, causing the curved portion 1043 to collide with the cover plate 1024, and further causing damage to the display screen 104.
[0064] Figure 5(a) is a schematic diagram of the cross-sectional variation of the falling state of the foldable electronic device.
[0065] A in Figure 5(a) is a schematic diagram of the overall foldable electronic device before falling. Among them, H1 is the cross-sectional plane of the foldable electronic device, and Q1 is the projection direction of the cross-sectional plane H1. B in Figure 5(a) is a top view of the foldable electronic device, wherein the cross-sectional line K1 is the projection of the cross-sectional plane H1 in the top view. C in Figure 5(a) is a partial schematic diagram of the cross-sectional view of the foldable electronic device in the Q1 direction. The cross-sectional view shown in C in Figure 5(a) is obtained by cutting according to A and B shown in Figure 5(a). D in Figure 5(a) is a partial schematic diagram of the foldable electronic device cut along the cross-sectional line K2 shown in C in Figure 5(a). E in Figure 5(a) is a simplified schematic diagram of the spatial relationship between the base and the curved portion before the foldable electronic device falls. Among them, the cross-sectional line K3 is the projection of the cross-sectional plane H1 in the side view direction.
[0066] Figure 5(b) is a partial enlarged schematic diagram corresponding to the M2 region of C in Figure 5(a). That is, only the cross-sectional schematic diagram of the region where the end of one side of the hinge assembly 102 extends a certain distance along the axial direction of the hinge assembly 102 from the end face of the hinge assembly 102 is shown. As shown in Figure 5(b), taking the axial side angle falling of the foldable electronic device in the folded state as an example, before the foldable electronic device falls, the curved portion 1043 has a projection region on the side surface of the cover plate 1024 facing the curved portion 1043, and the projection region on the surface has a gap with the curved portion 1043. The gap between each of the projection region and the curved portion 1043 is equal. That is, P1 and P2 shown in the figure are equal.
[0067] Figures 5(c) and 5(d) below are partial cross-sectional views corresponding to the area shown in Figure 5(b). Figure 5(c) is a partial cross-sectional view showing the drop state of the foldable electronic device. As shown in Figure 5(c), when the foldable electronic device is in the initial state of an axial angle drop, the axial angle (as shown in area M3 in Figure 5(c)) contacts the ground. At this time, the velocity of this contact area drops to 0, while other areas continue to fall due to inertia. The frame 105 and the display screen 104 generate displacement close to the pivot assembly 102. At this time, one end of the bent portion 1043 first contacts the cover plate 1024, i.e., P1 equals 0 as shown. There is a gap between the area extending a certain distance from the end face of the bent portion 1043 along the axial direction of the pivot assembly 102 and one side surface of the cover plate 1024, i.e., P2 has a certain distance as shown. For example, P2 equals 0.1 mm. At this time, the axial angle in area M3 is subjected to a large stress.
[0068] Figure 5(d) is a partial cross-sectional view showing the drop state of the foldable electronic device. As shown in Figure 5(d), when the foldable electronic device is in the final state of an axial angle drop, the bent portion 1043 is in complete contact with the surface of the cover plate 1024 facing the bent portion 1043, i.e., P1 equals 0 and P2 equals 0 as shown. At this time, the M3 region continuously bears a large stress. Figure 5(a)-Figure 5(d) As shown, during the drop state change of the foldable electronic device, the impact stress from the initial state to the final state of the axial corner drop is relatively large. Therefore, the setting method of the hinge assembly 102 in the traditional foldable electronic device can easily cause damage to the display screen 104 during the axial corner drop.
[0069] In order to address the problem that when a foldable electronic device is dropped, the bent portion 1043 will usually collide with the base used to set the pivot assembly 102, resulting in a high probability of damage to the bent portion 1043, this application embodiment shows a folding assembly.
[0070] The folding components shown in this application can be applied to foldable electronic devices, including but not limited to mobile phones, displays, tablets, and in-vehicle computers. This application does not impose any special limitations on the specific form of the aforementioned foldable electronic devices.
[0071] Figure 6 This is an exploded view of the first structure of the folding assembly shown in the embodiments of this application. Figure 6 As shown, the folding assembly may include: a first body 1, a second body 2 and a pivot 3. The pivot 3 may include a base 4, which may be disposed between the first body 1 and the second body 2. The base 4 includes a first surface 41 of the curved portion 51 facing the display screen 5 of the foldable electronic device.
[0072] In this embodiment, the axial direction of the substrate 4 is taken as the Y-axis, the thickness direction of the substrate 4 is taken as the Z-axis, and the direction perpendicular to the plane containing the Y-axis and Z-axis is taken as the X-axis. Wherein, as shown... Figure 6 The arrows shown indicate the positive directions of the X-axis, Y-axis, and Z-axis. The X-axis, Y-axis, and Z-axis directions mentioned in the following embodiments of this application shall all be based on these directions.
[0073] Figure 7 In the diagram, A is an overall schematic diagram of the first structure of the foldable component shown in the embodiment of this application. H2 is the cutting plane of the foldable electronic device, and Q2 is the projection direction of the cutting plane H2. Figure 7 B in the figure is a top view of the foldable electronic device shown in the embodiment of this application, wherein the section line R1 is the projection of the cutting plane H2 in the top view. Figure 7 C in the diagram is a partial schematic diagram of a cross-sectional view along the Q2 direction of the foldable electronic device shown in an embodiment of this application. For example... Figure 7 The cross-sectional view shown in C is based on, for example Figure 7 The image shows the result obtained by cutting through sections A and B. Figure 7 In this context, D represents a foldable electronic device along the edge. Figure 7 A partial schematic diagram showing the section line R2 shown in C. Figure 7 E in the diagram is a simplified schematic of the spatial relationship between the foldable electronic device's base and the curved portion. Section line R3 is the projection of the cutting plane H2 onto the side view direction.
[0074] It should be noted that the end of the folding component, i.e., the region corresponding to X1, includes the end of the base 4 and the end of the bent portion 51. The end of the bent portion 51 is formed by extending a certain distance along the Y-axis from one end face of the bent portion 51, and the end of the base 4 is formed by extending a certain distance along the Y-axis from one end face of the base 4. In this embodiment, the base 4 includes at least one end, and the bent portion 51 includes at least one end.
[0075] Figure 8 A in the example is as follows Figure 7 A magnified view of the M4 region corresponding to C. Figure 8 B in the example is as follows Figure 7 A partial 3D schematic diagram of region M4 in C.
[0076] like Figure 8 As shown in A and B, in some embodiments, at least one end of the bent portion 51 is formed by the end face of the bent portion 51 extending a first distance D1 along the Y-axis direction. For example, the first distance D1 can be 13 mm. It should be noted that the embodiments of this application do not set a specific value for the first distance D1; the first distance D1 can be less than or equal to 80 mm.
[0077] The first surface 41 comprises a recessed portion 411 and a support portion 412, wherein the support portion 412 is a region of the first surface 41 other than the recessed portion 411, at least one side end of the bending portion 51 forms a projection region M5 on the first surface 41 along a first direction, the recessed portion 411 is arranged corresponding to the projection region M5, and the recessed portion 411 contains the projection region M5. Wherein the first direction is the axial direction of the base body 4, that is, the Y-axis direction.
[0078] Along a second direction, the bending portion 51 has a first gap S1 with the recessed portion 411, and has a second gap S2 with the support portion 412, the first gap S1 is greater than the second gap S2, wherein the second direction is the thickness direction of the base body, that is, the Z-axis direction. In this way, the recessed portion 411 can avoid the display screen 5 when the foldable electronic device is axially dropped.
[0079] Further as shown in Figure 6 some embodiments, the base body 4 can comprise a shaft cover 42, a base 43 and a cover plate 44. Wherein the shaft cover 42 can be arranged opposite to the bending portion 51, the cover plate 44 is located between the shaft cover 42 and the bending portion 51, and is fixedly connected with the shaft cover 42 to form a cavity, and at least a part of the base 43 is located inside the cavity.
[0080] In some embodiments, the rotating shaft 3 can further comprise a swing arm assembly 6, and the swing arm assembly 6 can comprise a swing arm 61, a wedge block 62 and a door plate 63.
[0081] Further as shown in Figure 6 the display screen 5 is arranged on the first body 1 and the second body 2. According to different connection relationships of the display screen 5 with the first body 1 and the second body 2, the display screen 5 can comprise the bending portion 51, a first fixed portion 52 and a second fixed portion 53. The first fixed portion 52 is used for fixedly connecting with the first body 1, the second fixed portion 53 is used for fixedly connecting with the second body 2, the bending portion 51 corresponds to the positions of the swing arm assembly 6 and the base body 4, and is in a free state, and can produce relative displacement with the first fixed portion 52 and the second fixed portion 53 to adapt to the folding and unfolding functions of the folding assembly. When the folding assembly is in a folded state, the bending portion 51 can be in a water drop type bending state. It should be noted that the specific material of the display screen 5 can be arranged according to the display screen 104 in the above-mentioned embodiments, and the present application will not be described here.
[0082] The frame 7 can be arranged at the edges of the display screen 5, the first body 1 and the second body 2, and fixedly connected with these components to play a limiting and supporting role. It should be noted that the frame 7 can be integrally formed with the first body 1 and the second body 2, so that the first body 1, the second body 2 and the frame 7 together serve as a middle frame of the foldable electronic device. The frame 7 can also be fixedly connected with the first body 1 and the second body 2 as a part of the middle frame and as a shell of the foldable electronic device.
[0083] Figure 9 is a schematic view of a swing arm assembly and a base body according to an embodiment of the present application. As shown in Figure 9 , the swing arm 61 can be integrally formed with the wedge-shaped block 62, and a virtual sliding tongue (as shown in the M6 region in Figure 9 ) of the swing arm 61 is connected with an annular groove formed by the base 43 and the cover plate 44, and at the same time, the virtual sliding tongue is also connected with the virtual shaft of the door plate 63. Since the wedge-shaped block 62 is fixedly connected with the frame 7, and the display screen 5 is also fixedly connected with the frame 7, the displacement of the swing arm 11, the wedge-shaped block 12 and the door plate 13 relative to the base body 4 in the Z-axis direction can make the frame 7 and the display screen 5 change from the folded state to the unfolded state.
[0084] It should be noted that the rotating shaft 3 and the base body 4 each include but are not limited to the components shown in the embodiments of the present application, and the rotating shaft 3 and the base body 4 each can be provided with more or fewer components, which are not limited in the present application.
[0085] The first surface 41 can be a side surface of the cover plate 44 facing the curved portion 51, and when the base body 4 is of other structures not including the cover plate 44, the first surface 41 can also be a side surface of other components facing the curved portion 51. The embodiments of the present application do not limit the first surface 41 to be the surface of which component, and the first surface 41 can be the surface of any component that collides with the curved portion 51.
[0086] In some embodiments, the base 43 can be integrally formed with the shaft cover 42, and the base 43 can also be a separate structure from the shaft cover 42, and the embodiments of the present application do not limit the connection mode of the components of the rotating shaft 3 and the base body 4.
[0087] Figure 10 is a partial schematic view of a base body according to an embodiment of the present application. Figure 10 A in Figure 10 B in Figure 10As shown in A and B, in some embodiments, the recess 411 includes a first end 402 facing the end face 401 of the substrate 4, and a second distance D2 is provided between the end face 401 of the substrate 4 and the first end 402 along the Y-axis direction. Since the edge of the substrate 4 typically includes a portion of the shaft cover 42 for supporting the display screen 5 in the unfolded state of the foldable electronic device, the recess 411 does not need to be provided from the end face 401 of the substrate 4 to avoid the display screen 5; it only needs to be provided in the projection area of the first surface 41 corresponding to the end of the bent portion 51. In this case, the second distance D2 can be the thickness of the shaft cover 42. It should be noted that this application only uses the shaft cover 42 as an example, and the second distance D2 between the end face 401 of the substrate and the first end 402 of the recess 411 can also be provided as the structure of one or more other components. It should be noted that the area of the recess 411 can be greater than or equal to the projection area of the end of the bent portion 51 on the first surface 41, so as to provide a certain displacement space when the bent portion 51 experiences an axial angle drop, and to avoid the bent portion 51 colliding with the shaft cover 42.
[0088] In specific implementations, the recessed portion 411 can be configured as at least one of a groove or an inclined surface. This application embodiment does not limit the specific shape of the recessed portion 411; it can also be stepped or other shapes. Based on such groove, inclined surface, or stepped configurations, the height of the recessed portion 411 along the Z-axis is lower than the height of the support portion 412 along the Z-axis, allowing the recessed portion 411 to avoid impacting the display screen 5 during an isometric drop of the foldable electronic device. Therefore, any recessed portion 411 designed using such a configuration, or its derivative forms, can be applied to the embodiments of this application.
[0089] Figure 11 This is a top view schematic diagram of the first surface shown in an embodiment of this application. (See attached diagram.) Figure 11 As shown, the first surface 41 can be a smooth surface, or other components can be disposed thereon. In some embodiments, the inclined surface can include at least one of a continuous surface and a discontinuous surface. This application embodiment does not limit the continuity of the plane containing the recess 411. In some embodiments, the inclined surface can include at least one of an inclined curved surface and an inclined plane. In some embodiments, the inclined surface can be at least one of a curved surface with gradually increasing curvature and a curved surface with gradually decreasing curvature.
[0090] The first structure of the folding component in this application embodiment is exemplified by the recessed portion 411 as an inclined surface, and the inclined surface is a continuous curved surface.
[0091] Figure 12is a third distance schematic diagram provided by the embodiment of the present application. In some embodiments, the recess 411 comprises a second end 403 away from the end surface of the base 4, and the second end 403 and the end surface of the base 4 have a third distance D3, and the third distance D3 is greater than the second distance D2. Figure 12 A in FIG. 4 is a third distance profile schematic diagram shown by the embodiment of the present application. The profile is the same as the profile shown in A in FIG. 3. Figure 7 C in FIG. 4 is the same profile. Figure 12 B in FIG. 4 is a third distance three-dimensional schematic diagram shown by the embodiment of the present application. As shown in A and B in FIG. 4, the gap between the first end 402 and the second end 403 of the recess 411 and the corresponding curved portion 51 gradually decreases, and the gap between the support portion 412 and the corresponding curved portion 51 is unchanged. Figure 12 B in FIG. 4 is a third distance three-dimensional schematic diagram shown by the embodiment of the present application. As shown in A and B in FIG. 4, the gap between the first end 402 and the second end 403 of the recess 411 and the corresponding curved portion 51 gradually decreases, and the gap between the support portion 412 and the corresponding curved portion 51 is unchanged.
[0092] Figure 13(a)-Figure 13(f) is a recess schematic diagram provided by the embodiment of the present application.
[0093] FIG. 13(a) is a top view of the recess shown by the embodiment of the present application.
[0094] FIG. 13(b) is a three-dimensional view of the recess shown by the embodiment of the present application. As shown in FIG. 13(a) and FIG. 13(b), the recess 411 comprises a point O1, a point O2, a point O3, and a point O4. Among them, the point O1, the point O2, and the point O3 are the vertices in the top view of the recess 411. The point O2, the point O3, and the point O4 are the vertices in the side view of the recess 411.
[0095] FIG. 13(c) is a spatial position relationship of the point O1 shown by the embodiment of the present application. As shown in FIG. 13(b) and FIG. 13(c), the point O1 is in the plane where the support portion of the first surface 41 is located. Among them, the point O1 and the end surface of the base 4 have a first distance T1 along the Y axis in the negative direction. For example, the first distance T1 can be 13 millimeters. The base 4 has two side surfaces along the X axis direction, and the point O1 and the side surface of the base 4 along the X axis in the positive direction have a second distance T2. For example, the second distance T2 can be 3.7 millimeters. The point O1 and the side surface of the base 4 along the X axis in the negative direction have a third distance T3. For example, the third distance T3 can be 3.7 millimeters. The point O1 and the bottom surface of the base 4 have a fourth distance T4 along the Z axis in the negative direction. For example, the fourth distance T4 can be 6 millimeters.
[0096] Figure 13(d) is a spatial position relationship of point O2 according to an embodiment of the present application. As shown in Figure 13(d), point O2 is in the plane where the support portion of the first surface 41 is located. In this embodiment, point O2 and the end surface of the base 4 have a fifth distance T5 along the negative direction of the Y axis, which is 1 mm in an example. Point O2 and the side surface of the base 4 along the positive direction of the X axis have a sixth distance T6, which is 1.2 mm in an example. Point O2 and the side surface of the base 4 along the negative direction of the X axis have a seventh distance T7, which is 6.2 mm in an example. Since point O2 is in the same plane as point O1, the distance between point O2 and the bottom surface of the base 4 along the negative direction of the Z axis is the same as the fourth distance T4, which is not shown in the figure.
[0097] Figure 13(e) is a spatial position relationship of point O3 according to an embodiment of the present application. As shown in Figure 13(e), point O3 is in the plane where the support portion of the first surface 41 is located. In this embodiment, point O3 and the end surface of the base 4 have an eighth distance T8 along the negative direction of the Y axis, which is 1 mm in an example. Point O3 and the side surface of the base 4 along the positive direction of the X axis have a ninth distance T9, which is 6.2 mm in an example. Point O3 and the side surface of the base 4 along the negative direction of the X axis have a tenth distance T10, which is 1.2 mm in an example. Since point O3 is in the same plane as point O1, the distance between point O3 and the bottom surface of the base 4 along the negative direction of the Z axis is the same as the fourth distance T4, which is not shown in the figure.
[0098] Figure 13(f) is a spatial position relationship of point O4 according to an embodiment of the present application. As shown in Figure 13(f), point O4 is in the same plane as points O2 and O3, so the distance between point O4 and the end surface of the base 4 along the negative direction of the Y axis is the same as the eighth distance T8, which is not shown in the figure. Point O4 and the side surface of the base 4 along the positive direction of the X axis have an eleventh distance T11, which is 3.7 mm in an example. Point O4 and the side surface of the base 4 along the negative direction of the X axis have a twelfth distance T12, which is 3.7 mm in an example. Point O4 and the bottom surface of the base 4 along the negative direction of the Z axis have a thirteenth distance T13, which is 3 mm in an example.
[0099] Further as shown in FIG. 13(e) and as shown in FIG. 13(f), the axial length L1 of the recess 411 is the distance between the point O1 and the plane along the Z-axis direction where the first end 402 of the recess 411 is located. For example, the axial length L1 of the recess 411 can be 12 millimeters. The radial length L2 of the recess 411 is the distance between the projection of the point O2 and the point O3 in the radial direction. For example, the radial length L2 of the recess 411 can be 5 millimeters. Based on the structure in the above embodiment, the first gap S1 and the second gap S2 have a corresponding size relationship. In some embodiments, when the second gap S2 is 0.25 millimeters, the first gap S1 can be greater than 0.25 millimeters. For example, the first gap S1 is 0.3 millimeters.
[0100] wherein the first gap S1 can be designed according to the size of the second gap S2. If the value of the second gap S2 is small, the value of the first gap S1 can be designed to be relatively large to generate more avoidance for the display screen 5. If the value of the second gap S2 is large, since the bending part 51 and the base body 4 already have a certain avoidance space, the value of the first gap S1 can be designed to be relatively small. The present application does not limit the size of the first gap S1 and the second gap S2. The gap range shown in the embodiments of the present application is only used for exemplary description, and the specific gap size can be set according to the actual situation.
[0101] In some embodiments, when the foldable electronic device is in the folded state, the second gap S2 can be greater than or equal to 0.25 millimeters.
[0102] In some embodiments, when the foldable electronic device is in the folded state, the second gap S2 can be less than or equal to 0.4 millimeters.
[0103] In some embodiments, when the foldable electronic device is in the folded state, the difference between the first gap S1 and the second gap S2 is in the range of [0.1, 0.3] millimeters.
[0104] It should be noted here that the values involved in the above embodiments are only used for exemplary description, and the above values are only used to illustrate the spatial relationship formed by the points of the recess 411. Since the thirteenth distance T13 is less than the fourth distance T4, this height difference forms the recess 411. In this way, the base body 4 is thinner than the support part 412 due to the recess 411. In the case that the support part 412 can support the display screen 5, the recess 411 can also generate avoidance when the display screen 5 falls in the axial angle.
[0105] The recess 411 generated based on the numerical values in the above embodiments can make the subsidence amount of the first surface 41 small, and will not have a large impact on the strength of the first surface 41. Therefore, the technical solution shown in the embodiments of the present application will not have an impact on the supporting ability of the display screen 5 when the foldable electronic device is in the unfolded state.
[0106] FIG. 14(a) is a partial cross-sectional view of a falling state of a foldable electronic device. In FIG. 14(a), Figure 12 FIG. 14(b) is a partial cross-sectional view of a falling state of a foldable electronic device. Figure 7 The M4 region of the middle C corresponds to a partial enlarged view. As shown in FIG. 14(a), taking the falling of the foldable electronic device in the folded state as an example, the gap between the first end 402 and the second end 403 of the recess 411 and the bending part 51 gradually decreases before the falling of the foldable electronic device, that is, the first gap S1 shown in FIG. 14(a) is larger than the second gap S2. For example, S1 is 0.15 mm, and S2 is 0.1 mm.
[0107] FIG. 14(b) and FIG. 14(c) are both partial cross-sectional views corresponding to the regions shown in FIG. 14(a). FIG. 14(b) is a partial cross-sectional view of a falling state of a foldable electronic device. As shown in FIG. 14(b), in the initial state of the axial side angle falling of the foldable electronic device, the axial side angle (as shown in the M6 region of FIG. 14(b)) is in contact with the ground, at this time, the speed of this region is 0. Since the first surface 41 has the recess 411, the bending part 51 can continue to fall, at the same time, other regions continue to fall due to inertia, and the frame 7 and the bending part 51 produce displacement close to the first surface 41. In this process, one side end of the bending part 51 is not in contact with the first end of the recess 411, that is, the first gap S1 shown in the figure has a certain distance, and the second gap S2 has a certain distance. For example, S1 is 0.1 mm, and S2 is 0.1 mm. The avoidance of the first surface 41 to the bending part 51 in the initial state of the axial side angle falling can reduce the stress received by the bending part 51 in this process.
[0108] FIG. 14(c) is a partial cross-sectional view of a falling state of a foldable electronic device according to an embodiment of the present application. As shown in FIG. 14(c), in the end state of the axial side angle falling of the foldable electronic device, the bending part 51 is in complete contact with the first surface 41, that is, P1 shown in the figure is equal to 0, and P2 shown in the figure is equal to 0. At this time, since the initial state of the axial side angle falling has consumed a lot of stress, in the end state of the axial side angle falling, the stress borne by the M6 region is small, and the stress received by the bending part 51 is small, and will not cause large deformation of the display screen 5 to cause damage to the display screen 5.
[0109] In some embodiments, when the foldable electronic device is in the folded state, the first gap S1 is a first value, the second gap S2 is a second value, the first value is greater than the second value; when the foldable electronic device is in the unfolded state, the first gap S3 is a third value, the second gap S2 is a fourth value, the third value is greater than the fourth value; wherein the first value is different from the third value, and the second value is different from the fourth value. In this way, based on the first structure of the folding assembly, the gap between the recess 411 and the curved portion 51 changes in the folded state and the unfolded state of the foldable electronic device, producing different effects. When the foldable electronic device is in the folded state, the first gap S1 avoids the display screen 5 when the foldable electronic device is tilted, if the first gap S1 adopts a smaller first value, the influence on the support strength of the display screen 5 can be reduced while avoiding, if the first gap S1 adopts a larger first value, the support strength of the display screen 5 can be affected.
[0110] It should be noted that the present application only shows the case where the first value is different from the third value, and the second value is different from the fourth value. In specific implementation, the first value can be equal to the third value, and the second value can be equal to the fourth value, which is not limited by the present application.
[0111] In order to produce a better avoidance effect without affecting the support strength of the display screen 5. The folding assembly can further include a first rotating member 8, so that the first rotating member 8 can support the display screen 5 in the unfolded state of the foldable electronic device, avoiding the change of the support strength of the display screen 5 by the recess 411 of the first surface 41.
[0112] Figure 15 is a schematic diagram of the first rotating member structure shown in the present application. Figure 15 A in is a schematic diagram of the cross-sectional structure of the first rotating member shown in the present application. The schematic diagram is the same as Figure 7 The M4 region of C in is the same region. As shown in Figure 15 As shown in A in, the region between the recesses 411 of the first surface 41 is provided with a groove, and the first rotating member 8 is arranged in the groove. The first rotating member 8 includes a second surface 81, which is a side surface of the first rotating member 8 away from the bottom surface of the groove. The second surface 81 is parallel to the opening of the groove. Figure 15 B in is a schematic diagram of the unfolded state of the floating door plate shown in the present application. The first rotating member 8 can be connected with the swing arm 61, so that the first rotating member 8 can support the curved portion 51 in the unfolded state of the foldable electronic device. Figure 15 C in shows the cross-sectional view of the foldable electronic device in the unfolded state in the cross-sectional line R4 of A in Figure 15 C in shows the cross-sectional view of the foldable electronic device in the unfolded state in the cross-sectional line R4 of A in Figure 15C in FIG. 6 shows that when the foldable electronic device is in the unfolding process, the swing arm 61 drives the first rotating piece 8 to generate displacement along the Z-axis direction close to the display screen 5, thereby supporting the display screen 5 when the foldable electronic device is in the fully unfolded state. Figure 15 D in FIG. 6 shows that the foldable electronic device is in the folded state in the same view as Figure 15 A in FIG. 6 is a schematic view of the section at the section line R4. When the foldable electronic device is in the folded state, the swing arm 11 drives the first rotating piece 8 to generate displacement away from the display screen 5, thereby avoiding the display screen 5.
[0113] In this way, in the unfolded state of the foldable electronic device, the first rotating piece 8 can assist in supporting the display screen 5, making up for the influence of the first surface 41 on the supporting strength of the display screen 5 due to the setting of the recessed part 411.
[0114] The first structure of the folding assembly shown in the present application can set a recessed part 411 on the first surface 41 corresponding to at least one side end of the curved part 51 in the projection area of the first surface 41, so that in the thickness direction of the base body 4, the first gap S1 between the curved part 51 and the recessed part 411 is greater than the second gap S2 between the curved part 51 and the support part. In this way, the first gap S1 can avoid the display screen 5 when the foldable electronic device falls on the side, and reduce the impact stress of the display screen 5 on the folding assembly when the foldable electronic device falls on the side without affecting the overall strength of the folding assembly, thereby avoiding damage to the display screen 5 and improving the reliability of the foldable electronic device.
[0115] Figure 16 FIG. 7 is a schematic view of a second structure of the folding assembly shown in the embodiments of the present application in the H2 section.
[0116] As shown in FIG. 7, in some embodiments, the recessed part 411 can be set as an inclined curved surface, which can be a continuous curved surface. Figure 16
[0117] Among them, the first rotating piece 8 shown in the first structure of the folding assembly can be applied to other structures of the embodiments of the present application, and can be adaptively changed according to various structures to play a corresponding supporting role, which is not limited in the present application.
[0118] Figure 17 FIG. 8 is a schematic view of a third structure of the folding assembly shown in the embodiments of the present application.
[0119] Figure 17 C in FIG. 6 is a section view in the same section. As shown in FIG. 6, in some embodiments, the first rotating piece 8 can be set as a swing arm 61. Figure 7 Figure 17 As shown, in some embodiments, the recess 411 can be provided as an inclined curved surface, which can be an interrupted curved surface.
[0120] It should be noted here that other components of the folding assembly can be provided as described in the above embodiments, which will not be described herein.
[0121] Figure 18 is a fourth structural schematic diagram of the folding assembly according to an embodiment of the present application. As shown in Figure 18 As shown, in some embodiments, the recess 411 can be provided as a stepped shape.
[0122] In some embodiments, the folding assembly can be an axisymmetric assembly, or can be provided as an asymmetric assembly.
[0123] For example, since the foldable electronic device is provided with a camera on one side, when the axial side angle of the foldable electronic device falls, the falling angle of the axial side angle on the side provided with the camera can deviate from the falling angle of the axial side angle on the side not provided with the camera, based on which the axial length, radial length, and curvature of the recess 411 can be set differently to generate more structures of the folding assembly.
[0124] The embodiments of the present application also include one of the above folding assembly structures or a combination of multiple folding assembly structures, which will not be described herein.
[0125] The embodiments of the present application can select the recess 411 in multiple forms such as a groove, an inclined surface, and a stepped shape, and adaptively design the axial length and radial length of the recess 411 under the premise that the first gap S1 is greater than the second gap S2, thereby generating multiple structures of the folding assembly to reduce the impact stress between the display screen 5 and the folding assembly when the axial side angle of the foldable electronic device falls, avoid damage to the display screen 5, and improve the reliability of the foldable electronic device. The embodiments of the present application also provide a foldable electronic device, which includes the folding assembly provided in the above embodiments, and the foldable electronic device includes but is not limited to a mobile phone, a display, a tablet computer, a vehicle-mounted computer, and the like. The specific form of the foldable electronic device is not specially limited.
[0126] The foldable electronic device shown in the present application can be provided with the recess 411 in the projection area of the first surface 41 corresponding to both ends of the bending portion 51, so that the first gap S1 is greater than the second gap S2. In this way, the display screen 5 can be avoided when the axial side angle of the foldable electronic device falls, the impact stress between the display screen 5 and the folding assembly when the axial side angle of the foldable electronic device falls can be reduced without affecting the overall strength of the folding assembly, damage to the display screen 5 can be avoided, and the reliability of the foldable electronic device can be improved.
