[0033] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the side structure of the foldable electronic device 1000 provided in an embodiment of the present application when it is in a flattened state. Figure 2 A schematic diagram of the side structure of the foldable electronic device 1000 provided in an embodiment of the present application when it is in a folded state. The foldable electronic device 1000 provided in the present application may be a foldable mobile phone, a foldable tablet, a foldable e-book, etc. In the embodiment of the present application, a foldable mobile phone is taken as an example. The foldable electronic device 1000 has a flattened state and a folded state. During use, the foldable electronic device 1000 can switch between the flattened state and the folded state. Of course, in other embodiments, the foldable electronic device 1000 may also have one or more hovering states.

[0034] The foldable electronic device 1000 includes a flexible display screen 200 and a foldable housing 100. It can be understood that when the foldable electronic device 1000 is in a flat state, the flexible display screen 200 and the foldable housing 100 are in a flat state; when the foldable electronic device 1000 is in a folded state, the flexible display screen 200 and the foldable housing 100 are in a folded state.

[0037] Please refer to Figures 5 to 7 , Figure 5 This is a structural schematic diagram of one side of the foldable housing 100 provided in an embodiment of the present application when the base 10 and the first rotating shaft assembly 30 are in a flattened state. Figure 6 This is a structural schematic diagram of one side of the foldable housing 100 provided in an embodiment of the present application when the base 10 and the first rotating shaft assembly 30 are in a folded state. Figure 7 The foldable housing 100 provided in the embodiment of the present application is a cross-sectional schematic diagram of one side in a folded state. The foldable housing 100 includes a base 10 , a first housing 20 and a first rotating shaft assembly 30 .

[0038] The base 10 remains stationary during the state change of the foldable housing 100. In other words, the base 10 remains stationary when the foldable housing 100 switches between the flattened state and the folded state.

[0039] When the foldable housing 100 switches between the flattened state and the folded state, the first housing 20 rotates relative to the base 10. The first housing 20 has a first supporting surface 201 for supporting the flexible display screen 200. In a possible embodiment, the first housing 20 may be approximately a rectangular frame. The first housing 20 is supported on the non-display side of the flexible display screen 200. The first supporting surface 201 is a surface where the first housing 20 contacts the flexible display screen 200. The first supporting surface 201 may be a plane.

[0040] The first rotating shaft assembly 30 includes a first movable seat 301, a first connecting rod arm 302 and a first rotating arm 303. The first movable seat 301 is arranged at a distance on one side of the base 10 and is fixedly connected to the first shell 20. In the embodiment of the present application, the first movable seat 301 is arranged at a distance on the right side of the base 10 when the foldable shell 100 is in a flattened state. The first movable seat 301 and the first shell 20 can be fixedly connected by a detachable connection method or a non-detachable connection method. For example, the first movable seat 301 and the first shell 20 can be welded, bonded, bolted, or snap-fitted. The first connecting rod arm 302 is arranged between the first movable seat 301 and the base 10. The first connecting rod arm 302 is rotatably connected to the base 10 and is slidably connected to the first movable seat 301 along the first direction. It can be understood that the first connecting rod arm 302 can rotate relative to the base 10, and the first connecting rod arm 302 and the first movable seat 301 can slide along the first direction. The first connecting rod arm 302 and the base 10 can be connected to each other by the cooperation of the rotating shaft and the shaft hole, or the connection of the pin, or the cooperation of the arc block and the arc groove. The first connecting rod arm 302 and the first movable seat 301 can be connected to each other by the cooperation of the slider 321 and the slide groove 311, and the slider 321 and the guide rail. The first rotating arm 303 is arranged between the first movable seat 301 and the base 10. The first rotating arm 303 is connected to the base 10 and is connected to the first movable seat 301. It can be understood that the first rotating arm 303 can rotate relative to the base 10, and the first rotating arm 303 and the first movable seat 301 can rotate relative to each other. The first rotating arm 303 and the base 10 can be connected to each other by the cooperation of the rotating shaft and the shaft hole, or the connection of the pin, or the cooperation of the arc block and the arc groove. The first rotating arm 303 and the first movable seat 301 can be rotatably connected through the cooperation of a rotating shaft and an axial hole, or the connection of a pin shaft, or the cooperation of an arc block and an arc groove.

[0041] The first direction is inclined relative to the first support surface 201, and the first direction is inclined relative to the first support surface 201 at an angle greater than 45° and less than 85°. Figure 7 The first direction is inclined relative to the first support surface 201 at an angle as shown in FIG. Figure 7 As shown in α. Optionally, the first direction may be inclined at an angle of 50°, 55°, 60°, 70°, 77°, 80°, etc. relative to the first support surface 201. Taking the foldable shell 100 in the folded state as an example, when the foldable shell 100 falls, the foldable shell 100 is mainly subjected to a vertical downward force, and the first direction of the sliding connection between the first link arm 302 and the first movable seat 301 is inclined at an angle greater than 45° and less than 85° relative to the first support surface 201, and the first movable seat 301 is fixedly connected to the first shell 20, so the first link arm 302 will generate a certain vertical upward support force on the first shell 20, thereby preventing the first shell 20 from moving downward. In the present application, the first direction of the sliding connection between the first link arm 302 and the first movable seat 301 is inclined at an angle greater than 45° and less than 85° relative to the first support surface 201. It can also be understood that the first direction of the sliding connection between the first link arm 302 and the first movable seat 301 and the horizontal plane of the first shell 20 have an angle less than 45° and greater than 5°. The horizontal plane of the first shell 20 can refer to the attached Figure 7 As shown in surface b, the horizontal plane of the first shell 20 is perpendicular to the first supporting surface 201 .

[0042] The foldable shell 100 provided in the present application includes a base 10, a first shell 20 and a first rotating shaft assembly 30, wherein the first rotating shaft assembly 30 includes a first movable seat 301, a first connecting rod arm 302 and a first rotating arm 303, wherein the first movable seat 301 is fixedly connected to the first shell 20, the first connecting rod arm 302 is rotatably connected to the base 10 and is slidably connected to the first movable seat 301, and the first rotating arm 303 is rotatably connected to the base 10 and is rotatably connected to the first movable seat 301, so that the base 10, the first shell 20 and the first rotating shaft assembly 30 can form a crank slider 321 mechanism, so that the first shell 20 can rotate relative to the base 10 to be flattened or folded, and the first The first direction of the sliding connection between the link arm 302 and the first movable seat 301 is inclined relative to the first supporting surface 201 of the first shell 20 supporting the flexible display screen 200, and the inclination angle of the first direction relative to the first supporting surface 201 is greater than 45° and less than 85°. Therefore, the first link arm 302 can provide a certain supporting effect on the first shell 20, so that when the foldable shell 100 falls, especially when the foldable shell 100 falls in a folded state, the possibility of the first shell 20 driving the flexible display screen 200 to move can be reduced, the stress generated by the flexible display screen 200 can be alleviated, and the problem of easy damage to the flexible display screen 200 when falling can be optimized.

[0043] Furthermore, if Figure 8 As shown, Figure 8The foldable housing 100 provided in the embodiment of the present application is a cross-sectional schematic diagram in a folded state. The foldable housing 100 further includes a second housing 40 and a second rotating shaft assembly 50 .

[0044] When the foldable housing 100 switches between the flattened state and the folded state, the second housing 40 rotates relative to the base 10. The second housing 40 has a second supporting surface 401 for supporting the flexible display screen 200. In a possible embodiment, the second housing 40 may be approximately a rectangular frame. The second housing 40 is supported on the non-display side of the flexible display screen 200. The second supporting surface 401 is a surface where the second housing 40 contacts the flexible display screen 200. The second supporting surface 401 may be a plane.

[0045] The first non-bending display area 1 of the flexible display screen 200 is supported on the first support surface 201, the bending display area 2 is covered on the base 10, the first rotating shaft assembly 30 and the second rotating shaft assembly 50, and the second non-bending display area 3 is supported on the second support surface 401. The first non-bending display area 1 and the first supporting surface 201 can be fixedly connected. The second non-bending display area 3 and the second supporting surface 401 can be fixedly connected. Optionally, the non-display side of the first non-bending display area 1 is bonded to the first supporting surface 201, and the non-display side of the second non-bending display area 3 is bonded to the second supporting surface 401. When the flexible display screen 200 switches between the flattened state and the folded state, the first non-bending display area 1 and the second non-bending display area 3 are supported on the first shell 20 and the second shell 40, respectively, and do not bend.

[0046] When the foldable housing 100 is in the flattened state, the second housing 40 and the first housing 20 can be symmetrically flattened on opposite sides of the base 10. The foldable housing 100 is in the flattened state, which can be understood as the angle between the first housing 20 and the second housing 40 is 180° or close to 180°. The foldable housing 100 is in the folded state, which can be understood as the angle between the first housing 20 and the second housing 40 is 0° or close to 0°.

[0047] The second rotating shaft assembly 50 includes a second movable seat 501, a second connecting rod arm 502 and a second rotating arm 503. The second movable seat 501 is arranged at a distance on the other side of the base 10 and is fixedly connected to the second shell 40. In the embodiment of the present application, the second movable seat 501 is arranged at a distance on the right side of the base 10 when the foldable shell 100 is in a flattened state. The second movable seat 501 and the second shell 40 can be fixedly connected by a detachable connection method or a non-detachable connection method. For example, the second movable seat 501 and the second shell 40 can be welded, bonded, bolted, or snap-fitted. The second connecting rod arm 502 is arranged between the second movable seat 501 and the base 10. The second connecting rod arm 502 is rotatably connected to the base 10 and is slidably connected to the second movable seat 501 along the second direction. It can be understood that the second connecting rod arm 502 can rotate relative to the base 10, and the second connecting rod arm 502 and the second movable seat 501 can slide along the second direction. The second connecting rod arm 502 and the base 10 can be connected to each other by the cooperation of the rotating shaft and the shaft hole, or the connection of the pin, or the cooperation of the arc block and the arc groove. The second connecting rod arm 502 and the second movable seat 501 can be connected to each other by the cooperation of the slider 321 and the slide groove 311, and the slider 321 and the guide rail. The second rotating arm 503 is arranged between the second movable seat 501 and the base 10. The second rotating arm 503 is connected to the base 10 and is connected to the second movable seat 501. It can be understood that the second rotating arm 503 can rotate relative to the base 10, and the second rotating arm 503 and the second movable seat 501 can rotate relative to each other. The second rotating arm 503 and the base 10 can be connected to each other by the cooperation of the rotating shaft and the shaft hole, or the connection of the pin, or the cooperation of the arc block and the arc groove. The second rotating arm 503 and the second movable seat 501 can be rotatably connected through the cooperation of a rotating shaft and an axial hole, or the connection of a pin shaft, or the cooperation of an arc block and an arc groove.

[0048] The second direction is inclined relative to the second support surface 401, and the angle of inclination of the second direction relative to the second support surface 401 is greater than 45° and less than 85°. Figure 8 The angle of inclination of the second direction relative to the second supporting surface 401 can be referred to in the attached Figure 8As shown in β. Optionally, the second direction may be inclined at an angle of 50°, 55°, 60°, 70°, 77°, 80°, etc. relative to the second support surface 401. Taking the foldable shell 100 in the folded state as an example, when the foldable shell 100 falls, the foldable shell 100 is mainly subjected to a vertical downward force, and the second direction of the sliding connection between the second link arm 502 and the second movable seat 501 is inclined at an angle greater than 45° and less than 85° relative to the second support surface 401, and the second movable seat 501 is fixedly connected to the second shell 40, so the second link arm 502 will generate a certain vertical upward support force on the second shell 40, thereby preventing the second shell 40 from moving downward. In the present application, the second direction of the sliding connection between the second link arm 502 and the second movable seat 501 is inclined at an angle greater than 45° and less than 85° relative to the second support surface 401. It can also be understood that the second direction of the sliding connection between the second link arm 502 and the second movable seat 501 and the horizontal plane of the second shell 40 have an angle less than 45° and greater than 5°. The horizontal plane of the second shell 40 can refer to the attached Figure 8 As shown in plane d, the horizontal plane of the second shell 40 is perpendicular to the second supporting surface 401 .

[0049] The foldable housing 100 provided in this embodiment includes a base 10, a first housing 20, a first rotating shaft assembly 30, a second housing 40 and a second rotating shaft assembly 50. The first rotating shaft assembly 30 includes a first movable seat 301, a first connecting rod arm 302 and a first rotating arm 303, the first movable seat 301 is fixedly connected to the first housing 20, the first connecting rod arm 302 is rotatably connected to the base 10 and is slidably connected to the first movable seat 301, the first rotating arm 303 is rotatably connected to the base 10 and is rotatably connected to the first movable seat 301, so that the base 10, the first housing 20 and the first rotating shaft assembly 30 can form a crank slider 321 mechanism, so that the first housing 20 can rotate relative to the base 10 to be flattened or folded. The second rotating shaft assembly 50 includes a second movable seat 501, a second connecting arm 502 and a second rotating arm 503. The second movable seat 501 is fixedly connected to the second shell 40, the second connecting arm 502 is rotatably connected to the base 10 and is slidably connected to the second movable seat 501, and the second rotating arm 503 is rotatably connected to the base 10 and is rotatably connected to the second movable seat 501. Therefore, the base 10, the second shell 40 and the second rotating shaft assembly 50 can form a crank slider 321 mechanism, so that the second shell 40 can rotate relative to the base 10 to be flattened or folded. The first direction of the sliding connection between the first link arm 302 and the first movable seat 301 is inclined relative to the first supporting surface 201 of the first shell 20 supporting the flexible display screen 200, and the first direction is inclined at an angle greater than 45° and less than 85° relative to the first supporting surface 201. The second direction of the sliding connection between the second link arm 502 and the second movable seat 501 is inclined relative to the second supporting surface 401 of the second shell 40 supporting the flexible display screen 200, and the second direction is inclined at an angle greater than 45° and less than 85° relative to the second supporting surface 401. Therefore, the first link arm 3 02 can provide a certain supporting effect on the first shell 20, and the second connecting rod arm 502 can provide a certain supporting effect on the second shell 40, so that when the foldable shell 100 falls, especially when the foldable shell 100 is in a folded state and falls, the possibility of the first shell 20 driving the first non-bending display area 1 of the flexible display screen 200 to move and the possibility of the second shell 40 driving the second non-bending display area 3 of the flexible display screen 200 to move can be reduced, the stress generated on the flexible display screen 200 can be alleviated, and the problem of easy damage to the flexible display screen 200 when falling can be optimized.

Optionally, the slider 321 can be a rectangular slider, a square slider, etc. The slider 321 includes a first end face 3210 and a second end face 3211 that are arranged opposite to each other. It can be understood that the orientation of the first end face 3210 is opposite to the orientation of the second end face 3211. The first end face 3210 and the second end face 3211 are both planes. The first end face 3210 and the second end face 3211 both extend along the first direction. In other words, the first end face 3210 is inclined relative to the first support surface 201, and the first end face 3210 is inclined relative to the first support surface 201 at an angle greater than 45° and less than 85°, and the second end face 3211 is inclined relative to the first support surface 201, and the second end face 3211 is inclined relative to the first support surface 201 at an angle greater than 45° and less than 85°.

The first end face 3210 and the second end face 3211 both extend along the first direction, which can also be understood as the first end face 3210 and the second end face 3211 are both parallel to the first direction.

The slider 321 is received in the slide groove 311, and the first end surface 3210 contacts the first groove wall 3111, and the second end surface 3211 contacts the second groove wall 3112, so that the first link arm 302 is slidably connected to the first movable seat 301 along the first direction. When relative sliding occurs between the first connecting rod arm 302 and the first movable seat 301, the first end face 3210 maintains contact with the first groove wall 3111, and relative movement occurs between the first end face 3210 and the first groove wall 3111, and the second end face 3211 maintains contact with the second groove wall 3112, and relative movement occurs between the second end face 3211 and the second groove wall 3112.

The first groove wall 3111 and the second groove wall 3112 both extend along the first direction. The slider 321 is accommodated in the slide groove 311, and the first end face 3210 contacts the first groove wall 3111, and the second end face 3211 contacts the second groove wall 3112, so that the first connecting arm 302 and the first movable seat 301 can be slidably connected along the first direction, and the sliding contact area between the first connecting arm 302 and the first movable seat 301 is large, and the reliability of the sliding connection along the first direction is high, thereby increasing the supporting effect of the first connecting arm 302 on the first shell 20, and improving the reliability of the first connecting arm 302 supporting the first shell 20 when a fall occurs.

The first sub-connecting rod 3221 and the slider 321 may be connected in an integral manner, or the first sub-connecting rod 3221 and the slider 321 may be fixedly connected in a detachable or non-detachable manner. The second sub-connecting rod 3222 is located outside the slide groove 311. The second sub-connecting rod 3222 includes a third end face 322a facing opposite to the first end face 3210. It can be understood that the third end face 322a and the second end face 3211 have the same orientation. The third end face 322a contacts the side of the first groove wall 3111 away from the second groove wall 3112. When relative sliding occurs between the first link arm 302 and the first movable seat 301, the third end face 322a maintains contact with the first groove wall 3111, and relative movement occurs between the third end face 322a and the first groove wall 3111. In a possible embodiment, the third end face 322a may extend along the first direction, that is, the third end face 322a may be parallel to the first end face 3210.

The first arc block 323 is received in the first arc groove 101, and the first arc surface 3230 contacts the first arc wall 110, and the second arc surface 3231 contacts the second arc wall 112, so that the first link arm 302 is rotatably connected to the base 10. During the rotation of the first link arm 302 relative to the base 10, the first arc surface 3230 keeps in contact with the first arc wall 110, and the first arc surface 3230 and the first arc wall 110 rotate relative to each other, and the second arc surface 3231 keeps in contact with the second arc wall 112, and the second arc surface 3231 and the second arc wall 112 rotate relative to each other.

[0055] In this embodiment, the first link arm 302 and the base 10 are rotatably connected by the contact and cooperation of the arc block and the arc groove, which can reduce the parts of the foldable shell 100, facilitate the assembly of the first link arm 302 and the base 10, and enable the center of rotation of the first link arm 302 relative to the base 10 to be closer to the flexible display screen 200, thereby solving the technical problem of the rotatable connection between the first link arm 302 and the base 10 when the space between the flexible display screen 200 and the base 10 is small.

Fig.15 for Fig. 9 The cross-sectional schematic diagram of the first rotating arm 303 and the first movable seat 301 in the foldable shell 100 shown. The first rotating arm 303 includes a second arc block 330. The second arc block 330 includes a third arc surface 3301 and a fourth arc surface 3302 that are arranged opposite to each other. It can be understood that the direction of the third arc surface 3301 is opposite to the direction of the fourth arc surface 3302. The first movable seat 301 also has a second arc groove 312. The second arc groove 312 includes a third arc wall 3120 and a fourth arc wall 3121 that are arranged oppositely and spaced apart.

In addition, the second arc block 330 of the first rotating arm 303 can provide a certain support to the first shell 20 through the first movable seat 301, thereby forming a double support structure for the first shell 20 together with the first link arm 302, so as to reduce the possibility of the first shell 20 driving the flexible display screen 200 to move when the foldable shell 100 falls, especially when the foldable shell 100 falls in the folded state, relieve the stress generated by the flexible display screen 200, and optimize the problem of the flexible display screen 200 being easily damaged when falling.
