Abstract

A rotating shaft module (30), a housing mechanism (101), and an electronic device (100), relating to the technical field of smart devices. The rotating shaft module is connected to a bottom base (311) by means of a first sub-plate (3121); the first sub-plate is connected to a first base (13); a second sub-plate (3122) is connected to the bottom base; the second sub-plate is connected to a second base (23); a first movable arm (321) is slidably connected to the first base and is connected to the bottom base; and a second movable arm (331) is slidably connected to the second base and is connected to the bottom base. Thus, the rotating shaft module can rotate along different axes to achieve folding. In addition, the first movable arm is slidably connected to the first base, and the second movable arm is slidably connected to the second base to adjust a rotating shaft support (31), thereby reducing mutual interference between a display module (102) and the rotating shaft module, and thus allowing for a thinner design of the rotating shaft module.

[0034] Please refer to Figure 1, which is a schematic diagram of the structure of the electronic device in some embodiments of the present application when it is in a flattened state. The electronic device 100 may include a housing mechanism 101 and a display module 102 arranged on the housing mechanism 101. The housing mechanism 101 can be used to carry the display module 102, and electronic components such as circuit boards, batteries, and cameras can be installed inside. The display module 102 is used to display information. The display module 102 can be a display screen or other device with a display function that is well known to those skilled in the art. The display module 102 can be electrically connected to electronic components such as circuit boards, batteries, and cameras in the housing mechanism 101. The display module 102 can be made of soft material and can be deformed and bendable. In some embodiments, the display module 102 is a flexible display screen.

[0035] The housing mechanism 101 is foldable, which in turn drives the display module 102 to fold, achieving foldability. In Figure 1, the electronic device 100 is in a flattened state, the housing mechanism 101 is in a flattened state, the display module 102 is in a flattened state, and the display module 102 is located on one side of the housing mechanism 101. When the housing mechanism 101 bends and folds toward the side closer to the display module 102, the display module 102 is also bent and folded, and then the display module 102 bends and folds toward the side away from the housing mechanism 101. In some embodiments, the middle portion of the housing mechanism 101 can be bent and folded toward the side closer to the display module 102.

[0036] Please refer to Figures 1 and 2. Figure 2 is an exploded schematic diagram of a portion of the housing mechanism 101 in the embodiment shown in Figure 1. The housing mechanism 101 may include a first housing 10 for supporting and mounting a display module 102, a second housing 20 for supporting and mounting the display module 102, and a hinge module 30 connecting the first housing 10 and the second housing 20 and for supporting the display module 102. The first housing 10 and / or the second housing 20 may be used to support and mount electronic components such as circuit boards, batteries, and cameras. The first housing 10, the second housing 20, and the hinge module 30 work together to support and mount the display module 102. The hinge module 30 is foldable, allowing the first housing 10 and the second housing 20 to move as the hinge module 30 folds. Furthermore, the housing mechanism 101 folds in half as the hinge module 30 folds. In Figures 1 and 2 , when the housing mechanism 101 is in the flattened state, the first housing 10 and the second housing 20 are arranged side by side, and the hinge module 30 connects the first housing 10 and the second housing 20 between them. In some embodiments, when the housing mechanism 101 is in the flattened state, the hinge module 30 is connected to the side of the first housing 10 closer to the second housing 20, and to the side of the second housing 20 closer to the first housing 10.

[0037] It should be noted that the terms "first," "second," etc., herein and hereinafter, are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the technical features being referred to. Therefore, features defined as "first," "second," etc. may explicitly or implicitly include one or more of the aforementioned features.

[0038] When the housing mechanism 101 is in a flattened state, the display module 102 can be installed on the same side of the housing mechanism 101 , for example, the first housing 10 , the second housing 20 , and the hinge module 30 , for displaying information.

[0039] In Figures 1 and 2, the electronic device 100 can move the first housing 10 and the second housing 20 by folding the hinge module 30, so that the first housing 10 and the second housing 20 are stacked, achieving the electronic device 100, such as the housing mechanism 101, to fold in half. This in turn causes the display module 102 to fold in half at a location corresponding to the hinge module 30 as the first housing 10 and the second housing 20 move, thereby achieving the folding of the electronic device 100, such as the display module 102. The electronic device 100 can also unfold the first housing 10 and the second housing 20 by unfolding the hinge module 30, so that the display module 102 flattens as the first housing 10 and the second housing 20 unfold, thereby supporting the display module 102 and making it easier for the user to further use the display module 102. It is understood that the housing mechanism 101 can include not only two housings (such as the first housing 10 and the second housing 20) and the hinge module 30, but can also include multiple housings and multiple hinge modules 30. Two shells that need to be connected (eg, the first shell 10 and the second shell 20 ) among the multiple shells are connected via a hinge module 30 .

[0040] In some embodiments, when the housing mechanism 101 is fully folded after folding, the display module 102 may be located between the first housing 10 and the second housing 20. That is, the housing mechanism 101 folds toward the side closer to the display module 102 during the folding action. The housing mechanism 101 can protect the display module 102 and prevent it from being scratched in certain scenarios.

[0041] 1 and 2 , the housings, such as the first housing 10 and the second housing 20 , may be formed of plastic, glass, ceramic, fiber composite material, metal (such as stainless steel, aluminum, etc.) or other suitable materials or a combination of these materials.

[0042] Please refer to Figures 2 and 3. Figure 3 is a schematic diagram of the partial structure of the first housing 10 and the second housing 20 in the embodiment shown in Figure 2 when they are mated. The first housing 10 may include a first main housing 11 on one side of which the display module 102 is supported and mounted; a first flange 12 disposed on the side of the first main housing 11 facing the second housing 20 and configured to support the hinge module 30; a first base 13 disposed on the side of the first flange 12 near the display module 102 and configured to connect to the hinge module 30; and a first support plate 14 disposed on the side of the first base 13 away from the first flange 12 and cooperating with the first main housing 11 and the hinge module 30 to support the display module 102. In some embodiments, the first housing 10 and the second housing 20 in Figure 3 are arranged side by side when the housing mechanism 101 is in a flattened state.

[0043] The first main shell 11 may have an internal storage space for mounting electronic components such as circuit boards and batteries. In some embodiments, the first main shell 11 may support and mount a display module 102 on one surface in the thickness direction. The first flange 12 may extend from the first main shell 11 toward a side proximal to the second shell 20. Furthermore, the first flange 12 may cooperate with the first main shell 11, forming a first mounting space 1001 in the first shell 10 at a position corresponding to the first flange 12. The first shell 10 may then mount the first base 13, the first support plate 14, and the hinge module 30 within the first mounting space 1001.

[0044] In some embodiments, the surface of the first flange 12 on the side away from the display module 102 is flush with the surface of the first main housing 11 on the side away from the display module 102. The first installation space 1001 is provided on the side of the first flange 12 near the display module 102. The thickness of the first main housing 11 can be greater than the thickness of the first flange 12, so that there is a height difference between the first flange 12 on the side near the display module 102 and the first main housing 11, thereby forming the first installation space 1001 when they are mated.

[0045] The first base 13 can be fixed to the first main shell 11 and / or the first flange 12 by bonding, clamping, welding, screwing or welding. In some embodiments, the first base 13 can be a part of the first main shell 11 and / or the first flange 12.

[0046] A first slide rail 131 may be provided on the first base 13 for sliding connection with the hinge module 30. In some embodiments, the first slide rail 131 extends in a straight line, and the extension direction of the first slide rail 131 may be perpendicular to the thickness direction of the first main shell 11. In some embodiments, as shown in FIG3 , the first slide rail 131 extends in a direction toward or away from the second shell 20. In some embodiments, the first slide rail 131 may be a structure having a slide groove, a slider, a structure having a guide hole, a guide rod, or the like, and may also be a slide rail structure well known to those skilled in the art.

[0047] A first rotating portion 132 may be provided on the first base 13 to be rotatably connected to the hinge module 30. In some embodiments, the first rotating portion 132 may have a first rotating axis so that the hinge module 30 rotates around the first rotating axis when being rotatably connected to the hinge module 30. In some embodiments, the first rotating axis may be perpendicular to the extension direction of the first slide rail 131. In some embodiments, the first rotating axis may be perpendicular to the thickness direction of the first main shell 11. In some embodiments, the first rotating portion 132 is provided on a side of the first base 13 close to the display module 102. In some embodiments, the first rotating portion 132 may be a structure provided with a rotating hole or a rotating shaft, and of course, it may also be a structure that can realize rotation and is well known to those skilled in the art.

[0048] In some embodiments, the first base 13 may be part of the hinge module 30. In some embodiments, the first slide rail 131 and / or the first rotating portion 132 may be directly disposed on the first flange 12 and / or the first main housing 11. In some embodiments, the first rotating portion 132 is disposed on a side of the first base 13 away from the first flange 12.

[0049] The first support plate 14 can be fixed to the first base 13 and / or the first main shell 11 and / or the first flange 12 by bonding, clamping, welding, screwing, or welding, so that the first base 13 is located between the first flange 12 and the first support plate 14. In some embodiments, the first support plate 14 can cooperate with the first main shell 11 to support the display module 102, ensuring a smooth connection and transition between the portions of the display module 102 corresponding to the first main shell 11 and the first support plate 14. In some embodiments, the surface of the first support plate 14 away from the first flange 12 can be flush with the surface of the first main shell 11 near the display module 102, so as to cooperate with the first main shell 11 to support the display module 102. In some embodiments, the surface of the first support plate 14 away from the first flange 12 (i.e., the surface of the first support plate 14 supporting the display module 102) can be parallel to the extension direction of the first slide rail 131.

[0050] In some embodiments, the first support plate 14 may be a part of the first base 13 and / or the first main housing 11 and / or the first flange 12 . The first support plate 14 may be a part of the hinge module 30 .

[0051] Please refer to Figures 2, 3, and 4. Figure 4 is a partial structural diagram of the first housing 10 and the second housing 20 when they are mated in the embodiment shown in Figure 3, viewed from another perspective. The second housing 20 may include a second main housing 21 on one side of which the display module 102 is supported and mounted; a second flange 22 disposed on a side of the second main housing 21 facing the first housing 10, such as the first flange 12, and configured to support the hinge module 30; a second base 23 mounted on a side of the second flange 22 close to the display module 102 and configured to connect to the hinge module 30; and a second support plate 24 disposed on a side of the second base 23 away from the second flange 22 and cooperating with the second main housing 21 and the hinge module 30 to support the display module 102.

[0052] An accommodating space may be provided inside the second main shell 21 to carry and install electronic components such as circuit boards and batteries. In some embodiments, the second main shell 21 may carry and install the display module 102 on the surface of one side in the thickness direction. In some embodiments, when the electronic device 100 is in a flattened state, the second main shell 21 and the first shell 10, such as the first main shell 11, are both located on the same side of the display module 102. The second ridge 22 may extend from the second main shell 21 to a side close to the first shell 10, such as the first ridge 12. Furthermore, the second ridge 22 may cooperate with the second main shell 21, so that the second shell 20 forms a second installation space 2001 at a position corresponding to the second ridge 22, and the second shell 20 may install the second base 23, the second support plate 24 and the hinge module 30 in the second installation space 2001.

[0053] In some embodiments, when the electronic device 100 is in a flattened state, the second protrusion 22 can be spaced apart from or abut the first housing 10 , such as the first protrusion 12 , and can cooperate with each other to support the hinge module 30 .

[0054] In some embodiments, the surface of the second flange 22 on the side away from the display module 102 is flush with the surface of the second main housing 21 on the side away from the display module 102. The second installation space 2001 is provided on the side of the second flange 22 that is closer to the display module 102. The thickness of the second main housing 21 can be greater than the thickness of the second flange 22, so that there is a height difference between the second flange 22 on the side closer to the display module 102 and the second main housing 21, thereby forming the second installation space 2001 when mated.

[0055] In some embodiments, as shown in Figures 2, 3, and 4, the second installation space 2001 can communicate with the first installation space 1001 to jointly accommodate the shaft module 30. The second base 23 can be fixed to the second main housing 21 and / or the second flange 22 by bonding, clamping, welding, screwing, or welding. In some embodiments, the second base 23 can be a portion of the second main housing 21 and / or the second flange 22.

[0056] A second slide rail 231 may be provided on the second base 23 to be slidably connected to the hinge module 30. In some embodiments, the extension direction of the second slide rail 231 is a straight line, and the extension direction of the second slide rail 231 may be perpendicular to the thickness direction of the second main shell 21. In some embodiments, in Figures 3 and 4, the extension direction of the second slide rail 231 may be a direction toward or away from the first shell 10, such as the first base 13. The second slide rail 231 may be a structure provided with a slide groove, a slider, a structure provided with a guide hole, or a guide rod. Of course, it can also be a slide rail structure well known to those skilled in the art, and can even be arranged in the same manner as the first slide rail 131.

[0057] As shown in FIG. 3 and FIG. 4 , the extension direction of the second slide rail 231 may be parallel to or coincide with the extension direction of the first slide rail 131 .

[0058] A second rotating portion 232 may be provided on the second base 23 to be rotatably connected to the hinge module 30. In some embodiments, the second rotating portion 232 may have a second rotating axis so that the hinge module 30 rotates around the second rotating axis when being rotatably connected to the hinge module 30. In some embodiments, the second rotating axis may be perpendicular to the extension direction of the second slide rail 231. In some embodiments, the second rotating axis may be parallel to the first rotating axis. In some embodiments, the second rotating axis may be perpendicular to the thickness direction of the second main shell 21. In some embodiments, the second rotating portion 232 is provided on a side of the second base 23 close to the display module 102. In some embodiments, the second rotating portion 232 may be a structure provided with a rotating hole or a rotating shaft, and of course it may also be a structure that can realize rotation well known to those skilled in the art, and may even be provided in the same manner as the first rotating portion 132.

[0059] In some embodiments, the second base 23 may be part of the hinge module 30. The second slide rail 231 and / or the second rotating portion 232 may be directly disposed on the second flange 22 and / or the second main housing 21. The second rotating portion 232 is disposed on a side of the second base 23 away from the second flange 22.

[0060] The second support plate 24 can be fixed to the second base 23 and / or the second main housing 21 and / or the second flange 22 by bonding, clamping, welding, screwing, or welding, so that the second base 23 is located between the second flange 22 and the second support plate 24. In some embodiments, the second support plate 24 can cooperate with the second main housing 21 to support the display module 102, ensuring a smooth connection and transition between the portions of the display module 102 corresponding to the second main housing 21 and the second support plate 24. In some embodiments, the surface of the second support plate 24 away from the second flange 22 can be flush with the surface of the second main housing 21 near the display module 102, so as to cooperate with the second main housing 21 to support the display module 102. In some embodiments, the surface of the second support plate 24 away from the second flange 22 (i.e., the surface of the second support plate 24 supporting the display module 102) can be parallel to the extension direction of the second slide rail 231.

[0061] In some embodiments, the second support plate 24 may be part of the second base 23 and / or the second main housing 21 and / or the second flange 22. As shown in Figures 3 and 4, the second support plate 24 may be disposed opposite the first support plate 14. The surface of the second support plate 24 facing away from the second flange 22 may be flush with the surface of the first support plate 14 facing away from the first flange 12. The second support plate 24 may be part of the hinge module 30.

[0062] Referring to FIG. 2 , the hinge module 30 may include a hinge bracket 31 disposed within the first installation space 1001 and the second installation space 2001, a first connecting component 32 rotatably connected to the hinge bracket 31 and connected to the first housing 10, such as the first base 13, and a second connecting component 33 rotatably connected to the hinge bracket 31 and connected to the second housing 20, such as the second base 23. The hinge bracket 31 may be used to support the display module 102. The first connecting component 32 connects the hinge module 30, such as the hinge bracket 31, to the first housing 10, such as the first base 13. The second connecting component 33 connects the hinge module 30, such as the hinge bracket 31, to the second housing 20, such as the second base 23. When the first connecting component 32 and the second connecting component 33 rotate separately within the hinge module 30, the housing mechanism 101 can be folded.

[0063] Referring to Figure 2 , the hinge bracket 31 can be made of a rigid material. The hinge bracket 31 can include a base 311 disposed within the first installation space 1001 and the second installation space 2001, and a support plate 312 disposed on a side of the base 311 proximal to the display module 102. The base 311 and support plate 312 are fixedly connected and can be coupled to the first connecting assembly 32 and the second connecting assembly 33. The support plate 312 can cooperate with the first housing 10, such as the first main housing 11 and the first support plate 14, and the second housing 20, such as the second main housing 21 and the second support plate 24, to support the display module 102.

[0064] The base 311 can be mounted on the first housing 10, such as the first flange 12, and the second housing 20, such as the second flange 22, thereby covering the gap between the first housing 10, such as the first flange 12, and the second housing 20, such as the second flange 22, thereby improving the appearance of the electronic device 100. In some embodiments, when the housing mechanism 101 is folded into the folded state, the gap between the first housing 10, such as the first flange 12, and the second housing 20, such as the second flange 22, is widened, exposing the base 311. The base 311 can then precisely cover the gap between the first housing 10, such as the first flange 12, and the second housing 20, such as the second flange 22.

[0065] The support plate 312 can be fixed to the base 311 by bonding, clamping, welding, screwing or welding, so that the support plate 312 is located on the side of the base 311 facing the display module 102. In some embodiments, the support plate 312 is fixed to the side of the base 311 facing the display module 102.

In some embodiments, the second limiting axis may be parallel to the second rotation axis. In some embodiments, the second limiting axis may be parallel to the first limiting axis. In some embodiments, the second limiting axis is located on the side of the support plate 312 away from the base 311. In some embodiments, the second limiting axis and the first limiting axis are respectively at the same distance from the display module 102. In some embodiments, the distance between the second limiting axis and the second rotation axis is equal to the distance between the first limiting axis and the first rotation axis. In some embodiments, the second limiting axis is parallel to the plane of the first limiting axis and the surface of the support plate 312 on the side away from the base 311 (i.e., the surface of the support plate 312 on which the display module 102 is mounted). In some embodiments, the second sliding portion 3132 is located on the side of the surface of the support plate 312 on which the display module 102 is mounted that is closer to the base 311.

In some embodiments, the first pivoting portion 3141 may have a first pivot axis, so that when rotatably connected with the first connecting assembly 32, the first connecting assembly 32 can rotate about the first pivot axis. In some embodiments, the first pivot axis may be perpendicular to the extension direction of the first slide rail 131. In some embodiments, the first pivot axis may be parallel to the first limiting axis. In some embodiments, the first pivot axis may be located within the support plate 312. In some embodiments, the first pivot axis is further away from the display module 102 than the first limiting axis. In some embodiments, the first pivoting portion 3141 is located on the side of the support plate 312 closest to the base 311. In some embodiments, the first pivoting portion 3141 may be provided with a rotating hole or a rotating shaft. Of course, it may also be any rotatable structure known to those skilled in the art, and may even be configured in the same manner as the first rotating portion 132.

In some embodiments, the second pivot axis is parallel to the plane where the first pivot axis is located and the surface of the support plate 312 on the side away from the base 311 (i.e., the surface of the support plate 312 that supports and installs the display module 102). In some embodiments, the midpoint of the shortest line connecting the second pivot axis and the first limit axis and the midpoint of the shortest line connecting the first pivot axis and the second limit axis can both be located on a straight line parallel to the second pivot axis. In some embodiments, the second pivot portion 3142 is located on the side of the support plate 312 close to the base 311. In some embodiments, the second pivot portion 3142 can be a structure with a rotating hole or a rotating shaft, and of course it can also be a structure that can realize rotation known to those skilled in the art, and can also be set in the same manner as the first pivot portion 3141, or even in the same manner as the second rotating portion 232.

In some embodiments, as shown in Figure 2, the first support plate 14 can cooperate with the support plate 312 to shield the first movable arm 321, thereby achieving support and installation of the display module 102 while reducing contact between the first movable arm 321 and the display module 102.

Alternatively, when the first sliding portion 3131 slides in the direction in which the first sliding end 3221 extends, the support plate 312 can rotate relative to the first sliding end 3221 about the first limiting axis, or the first sliding end 3221 can rotate relative to the support plate 312 about the first limiting axis. Furthermore, in some embodiments, the extension direction of the first sliding end 3221 is an arc. In some embodiments, the configuration of the first sliding end 3221 allows the first connecting arm 322 to rotate about the first limiting axis when it slides in the direction in which the first sliding end 3221 extends. In some embodiments, the first limiting axis is closer to the display module 102 than the first pivot axis. In some embodiments, the first sliding end 3221 may be a structure provided with an arc-shaped slide, an arc-shaped slider, or an arc-shaped slide groove, so that the first sliding end 3221 and the first sliding portion 3131 can be slidably connected by the arc-shaped slider extending into the arc-shaped slide groove. Or the sliding connection can be achieved by the arc-shaped slider extending into the arc-shaped slide groove.

Of course, the matching method of the first rotating end 3222 and the first rotating portion 132 can also adopt a matching method well known to those skilled in the art or a formula method disclosed in other embodiments of the present application to achieve rotational connection, and is not limited to the rotational connection methods listed here.

[0077] 2 , 5 , and 6 , the second connecting assembly 33 may include a second movable arm 331 that is slidably connected to the second housing 20, such as the second base 23, and rotatably connected to the shaft bracket 31, such as the support plate 312, and a second connecting arm 332 that is rotatably connected to the second housing 20, such as the second base 23, and rotatably connected to the shaft bracket 31, such as the support plate 312. The second movable arm 331 cooperates with the second connecting arm 332 to achieve the connection between the shaft bracket 31 and the second housing 20.

In some embodiments, as shown in FIG2 , the second support plate 24 can cooperate with the support plate 312 to shield the second movable arm 331, thereby achieving support and installation of the display module 102 while reducing contact between the second movable arm 331 and the display module 102.

[0079] In some embodiments, a second pivot end 3311 is provided at one end of the second movable arm 331 to be rotatably connected to the support plate 312, such as the second pivot portion 3142. Furthermore, the second movable arm 331 can rotate relative to the support plate 312 around the second pivot axis. The support plate 312 can rotate relative to the second movable arm 331 around the second pivot axis. In some embodiments, the second pivot end 3311 can be a structure provided with a rotating hole or a rotating shaft, so that the second pivot end 3311 and the second pivot portion 3142 can be rotatably connected by a matching method in which the rotating shaft extends into the rotating hole and rotates. Of course, the matching method of the second pivot end 3311 and the second pivot portion 3142 can also adopt a matching method well known to those skilled in the art or a formula method disclosed in other embodiments of the present application to achieve a rotational connection, and is not limited to the rotational connection methods listed here.

[0080] In some embodiments, the other end of the second movable arm 331 is provided with a second movable end 3312 for sliding connection with the second base 23, such as the second slide rail 231. Furthermore, the second movable arm 331 can slide in the direction of the second slide rail 231 and can move toward or away from the side of the second housing 20, such as the second main housing 21. In some embodiments, the second movable end 3312 can be a structure provided with a slide groove, a slider, a structure provided with a guide hole, or a guide rod. Furthermore, the second movable end 3312 can be slidably connected to the second slide rail 231 by a slider extending into the slide groove and sliding therein.

The sliding connection is not limited to the sliding connection methods listed here.

[0081] One end of the second connecting arm 332 can extend between the base 311 and the support plate 312 to connect to the support plate 312, and the other end can extend between the second flange 22 and the second support plate 24 to connect to the second base 23. In some embodiments, as shown in Figure 2, the second support plate 24 can cooperate with the support plate 312 to shield the second connecting arm 332, thereby achieving support installation of the display module 102 while reducing contact between the second connecting arm 332 and the display module 102.

[0082] In some embodiments, one end of the second connecting arm 332 is provided with a second sliding end 3321 for sliding connection with the support plate 312, such as the second sliding portion 3132. Furthermore, the second sliding end 3321 slides in the direction in which the second sliding portion 3132 extends, allowing the second sliding end 3321 to rotate relative to the support plate 312 about the second limiting axis, or the support plate 312 to rotate relative to the second sliding end 3321 about the second limiting axis. Alternatively, when the second sliding portion 3132 slides in the direction in which the second sliding end 3321 extends, the support plate 312 can rotate relative to the second sliding end 3321 about the second limiting axis, or the second sliding end 3321 can rotate relative to the support plate 312 about the second limiting axis. Furthermore, in some embodiments, the extension direction of the second sliding end 3321 is an arc. In some embodiments, the configuration of the second sliding end 3321 allows the second connecting arm 332 to rotate about the second limiting axis when it slides in the direction in which the second sliding end 3321 extends. In some embodiments, the second limiting axis is closer to the display module 102 than the second pivot axis. In some embodiments, the second sliding end 3321 may be a structure provided with an arc-shaped slide, an arc-shaped slider, or an arc-shaped slide groove, so that the second sliding end 3321 and the second sliding portion 3132 can be slidably connected by the arc-shaped slider extending into the arc-shaped slide groove. Alternatively, the sliding connection can be achieved by the arc-shaped slider extending into the arc-shaped slide groove. Of course, the second sliding end 3321 and the second sliding portion 3132 can also be slidably connected by a method well known to those skilled in the art or by a disclosed formula method for cooperating between different structures in other embodiments of the present application, and are not limited to the sliding connection methods listed here.

[0083] In some embodiments, the other end of the second connecting arm 332 is provided with a second rotating end 3322 to be rotatably connected to the second base 23, such as the second rotating portion 232. Furthermore, the second connecting arm 332 can rotate relative to the second base 23 around the second rotating axis. The second base 23 can rotate relative to the second connecting arm 332 around the second rotating axis. In some embodiments, the second rotating end 3322 can be a structure provided with a rotating hole or a rotating shaft, so that the second rotating end 3322 and the second rotating portion 232 can be rotatably connected by a matching method in which the rotating shaft extends into the rotating hole and rotates. Of course, the matching method of the second rotating end 3322 and the second rotating portion 232 can also adopt a matching method well known to those skilled in the art or a formula method disclosed in other embodiments of the present application to achieve rotational connection, and is not limited to the rotational connection methods listed here.

[0084] Please refer to Figures 1 to 7. Figure 7 is a schematic diagram of the partial structure of the electronic device 100 in the embodiment shown in Figure 1 when it is in a fully folded state. Due to the arrangement of the first support plate 14 and the second support plate 24, the first support plate 14 cannot move relative to the first main housing 11 when the electronic device 100 is folded or unfolded, and the second support plate 24 cannot move relative to the second main housing 21 when the electronic device 100 is folded or unfolded. This causes the display module 102 to form the "U" shape shown in Figure 7. In Figure 7, when the display module 102 is folded in half, the portion of the display module 102 corresponding to the hinge module 30 forms a curved structure similar to a semicircle. In some embodiments, when the display module 102 is folded in half, the portion of the display module 102 corresponding to the hinge module 30 forms a curved structure similar to a semicircle. The present application provides a hinge module 30 to accommodate the "U" shape of the display module 102.

[0085] In FIG1 , the electronic device 100 is in a flattened state. The hinge bracket 31, such as the support plate 312, cooperates with the first housing 10, such as the first main housing 11, the first support plate 14, the second housing 20, such as the second main housing 21, and the second support plate 24 to support the display module 102. The first support plate 14 can cooperate with the support plate 312 to shield the first movable arm 321 and the first connecting arm 322, thereby supporting and mounting the display module 102 while reducing contact between the first movable arm 321 and the first connecting arm 322 and the display module 102. The second support plate 24 can cooperate with the support plate 312 to shield the second movable arm 331 and the second connecting arm 332, thereby supporting and mounting the display module 102 while reducing contact between the second movable arm 331 and the second connecting arm 332 and the display module 102.

[0086] When folding the electronic device 100, force can be applied to the first housing 10, such as the first main housing 11, and the second housing 20, such as the second main housing 21, so that the housing mechanism 101 bends toward the side closer to the display module 102. Furthermore, the first housing 10, such as the first main housing 11, bends toward the side closer to the display module 102. Under the condition that the first base 13, such as the first slide rail 131, and the first connecting component 32, such as the first movable arm 321, can only slide but not rotate, the first housing 10, such as the first main housing 11, can only rotate through the first connecting component 32, such as the first movable arm 321, and the support plate 312, such as the first pivot portion 3141, and rotates around the first pivot axis. At the same time, the first housing 10, such as the first main housing 11, can rotate through the first connecting component 32, such as the first connecting arm 322, and the support plate 312, such as the first sliding portion 3131, and rotates around the first limit axis. When the first limiting axis and the first pivot axis do not coincide, spatial interference occurs between the first connecting arm 322, the first movable arm 321, and the first base 13. This spatial interference can only be resolved by rotatably connecting the first housing 10, such as the first main housing 11, and the first connecting component 32, such as the first connecting arm 322, and rotating about the first rotation axis in conjunction with sliding movement between the first base 13, such as the first slide rail 131, and the first connecting component 32, such as the first movable arm 321. The first connecting component 32, such as the first movable arm 321, moves away from the first housing 10, such as the first main housing 11.

[0087] Because the housing mechanism 101 bends toward the side closer to the display module 102, the portion of the display module 102 corresponding to the hinge module 30 is pressed against the support plate 312 when folded. The first connecting component 32, such as the first movable arm 321, moves toward the side away from the first housing 10, such as the first main shell 11, causing the support plate 312 to move away from the display module 102, leaving space for the display module 102. This allows the display module 102 to assume a "U" shape when the electronic device 100 is fully folded. It is understood that if the support plate 312 does not give way to the display module 102, the display module 102 will assume a teardrop shape when the electronic device 100 is fully folded, rather than a "U" shape. Furthermore, to accommodate the teardrop shape of the display module 102, the prior art also requires the first support plate 14 to be provided as a rotating member to give way to the display module 102 during rotation without moving the hinge bracket 31, such as the support plate 312.

[0088] Furthermore, the second housing 20, such as the second main housing 21, is bent toward the side closer to the display module 102. Under the restriction that the second base 23, such as the second slide rail 231, and the second connecting component 33, such as the second movable arm 331, can only slide but not rotate, the second housing 20, such as the second main housing 21, can only rotate through the second connecting component 33, such as the second movable arm 331, and the support plate 312, such as the second pivot portion 3142, and rotate about the second pivot axis. Simultaneously, the second housing 20, such as the second main housing 21, can rotate through the second connecting component 33, such as the second connecting arm 332, and the support plate 312, such as the second sliding portion 3132, and rotate about the second restricted axis. When the second limiting axis and the second pivot axis do not coincide, spatial interference occurs between the second connecting arm 332, the second movable arm 331, and the second base 23. This spatial interference can only be resolved by rotatably connecting the second housing 20, such as the second main housing 21, and the second connecting component 33, such as the second connecting arm 332, and rotating about the second rotation axis in conjunction with sliding movement between the second base 23, such as the second slide rail 231, and the second connecting component 33, such as the second movable arm 331. The second connecting component 33, such as the second movable arm 331, moves away from the second housing 20, such as the second main housing 21.

[0089] Because the housing mechanism 101 bends toward the side closer to the display module 102, the portion of the display module 102 corresponding to the hinge module 30 is pressed against the support plate 312 when folded. The second connecting assembly 33, such as the second movable arm 331, moves toward the side away from the second housing 20, such as the second main housing 21, causing the support plate 312 to move away from the display module 102, leaving space for the display module 102. This allows the display module 102 to assume a "U" shape when the electronic device 100 is fully folded. It is understood that if the support plate 312 does not give way to the display module 102, the display module 102 will assume a teardrop shape when the electronic device 100 is fully folded, rather than a "U" shape. Furthermore, to accommodate the teardrop shape of the display module 102, the prior art also requires the provision of a second support plate 24 as a rotating member to give way to the display module 102 during rotation without moving the hinge bracket 31, such as the support plate 312.

[0090] In some embodiments, when the electronic device 100 is in a fully folded state, the surface of the first housing 10 , such as the first support plate 14 , supporting the display module 102 and the surface of the second housing 20 , such as the second support plate 24 , supporting the display module 102 may be arranged parallel.

[0091] In some embodiments, referring to Figures 8 and 9 , Figure 8 is a schematic diagram of a portion of the structure of the rotating shaft module 30 in the embodiment shown in Figure 2 , and Figure 9 is an exploded view of the rotating shaft module 30 in the embodiment shown in Figure 8 . The first support plate 14 can be secured to the first movable arm 321 by bonding, clamping, welding, screwing, or welding, such that the first base 13 is positioned between the first flange 12 and the first support plate 14. The first support plate 14 can be a portion of the first movable arm 321.

[0092] In some embodiments, the first sliding portion 3131 extends in an arc direction, the first pivoting portion 3141 extends in an arc direction, and the arc radius of the first sliding portion 3131 is greater than the arc radius of the first pivoting portion 3141 .

[0093] In some embodiments, the second sliding portion 3132 extends in an arc, the second pivoting portion 3142 extends in an arc, and the arc radius of the second sliding portion 3132 is greater than the arc radius of the second pivoting portion 3142 .

[0094] 8 and 9 , the second support plate 24 can be fixed to the second movable arm 331 by bonding, clamping, welding, screwing, or welding, so that the second base 23 is located between the second flange 22 and the second support plate 24. The second support plate 24 can be part of the second movable arm 331.

[0095] In some embodiments, please refer to Figure 10, which is a partially enlarged schematic diagram of the hinge module 30 in some embodiments of the embodiment shown in Figure 9. The first pivot end 3211 and the first movable end 3212 are both disposed on the first support plate 14. Furthermore, in some embodiments, the first movable arm 321 may be omitted, and the first pivot end 3211 and the first movable end 3212 may be formed as part of the first support plate 14.

[0096] 10 , the second pivot end 3311 and the second movable end 3312 are both disposed on the second support plate 24. The second movable arm 331 may be omitted, and the second pivot end 3311 and the second movable end 3312 may be part of the first support plate 14.

[0097] In some embodiments, as shown in FIG9 , the support plate 312 can be omitted from the hinge bracket 31 to reduce the thickness of the hinge bracket 31 and, in turn, reduce the thickness of the electronic device 100. Accordingly, the first sliding portion 3131 , the second sliding portion 3132 , the first pivoting portion 3141 , and the second pivoting portion 3142 can be disposed on the base 311 .

[0098] In some embodiments, referring to FIG8 , the first support plate 14 and the second support plate 24 can extend above the base 311, replacing all or part of the support plate 312 in FIG2 , acting as the support plate 312 and cooperating with each other to support the display module 102. Furthermore, the support plate 312 can be omitted. Of course, the support plate 312 can also be present and configured using the above-described embodiment. Furthermore, the shape of the support plate 312 can be configured to cooperate with the first support plate 14 and the second support plate 24 in FIG8 . In some embodiments, the first support plate 14 and the second support plate 24 can shield the base 311, so that the base 311 does not directly contact the display module 102 when the electronic device 100 is in the flattened state. In some embodiments, when the electronic device 100 is in the flattened state, the base 311 is located between the first flange 12 and the first support plate 14, and between the second flange 22 and the second support plate 24.

[0099] Please refer to Figures 8 and 11. Figure 11 is a schematic diagram of the partial structure of the electronic device 100 in the embodiment shown in Figure 1 when the hinge module 30 of Figure 8 is in a fully folded state. When the electronic device 100 is in a flattened state based on the hinge module 30 of Figure 8, the first housing 10, such as the first main housing 11, the first support plate 14, the second housing 20, such as the second main housing 21, and the second support plate 24 support the display module 102. The first support plate 14 shields the first movable arm 321 and the first connecting arm 322, thereby supporting the display module 102 while reducing contact between the first movable arm 321 and the first connecting arm 322 and the display module 102. The second support plate 24 shields the second movable arm 331 and the second connecting arm 332, thereby supporting the display module 102 while reducing contact between the second movable arm 331 and the second connecting arm 332 and the display module 102.

[0100] When folding the electronic device 100, force can be applied to the first housing 10, such as the first main housing 11, and the second housing 20, such as the second main housing 21, so that the housing mechanism 101 bends toward the side closer to the display module 102. Furthermore, the first housing 10, such as the first main housing 11, bends toward the side closer to the display module 102. Under the condition that the first base 13, such as the first slide rail 131, the first connecting component 32, such as the first movable arm 321, and the first support plate 14 can only slide but not rotate, the first housing 10, such as the first main housing 11, can only rotate through the first connecting component 32, such as the first movable arm 321, the first support plate 14, and the base 311, such as the first pivot portion 3141, and rotates about the first pivot axis. At the same time, the first housing 10, such as the first main housing 11, can rotate through the first connecting component 32, such as the first connecting arm 322, and the base 311, such as the first sliding portion 3131, and rotates about the first limiting axis. When the first limiting axis and the first pivot axis do not coincide, spatial interference occurs between the first connecting arm 322, the first movable arm 321 (and the first support plate 14), and the first base 13. This spatial interference can only be resolved by rotating the first housing 10, such as the first main housing 11, and the first connecting component 32, such as the first connecting arm 322, around the first rotation axis, in conjunction with the sliding movement of the first base 13, such as the first slide rail 131, and the first connecting component 32, such as the first movable arm 321 (and the first support plate 14). The first connecting component 32, such as the first movable arm 321, and the first support plate 14 move away from the first housing 10, such as the first main housing 11.

[0101] Furthermore, the second housing 20, such as the second main housing 21, is bent toward the side closer to the display module 102. When the second base 23, such as the second slide rail 231, the second connecting assembly 33, such as the second movable arm 331, and the second support plate 24 are limited in a sliding manner but not in a rotating manner, the second housing 20, such as the second main housing 21, can only rotate through the second connecting assembly 33, such as the second movable arm 331, the first support plate 14, and the base 311, such as the second pivoting portion 3142, and rotate about the second pivot axis. Simultaneously, the second housing 20, such as the second main housing 21, can rotate through the second connecting assembly 33, such as the second connecting arm 332, and the base 311, such as the second sliding portion 3132, and rotate about the second limiting axis. When the second limiting axis and the second pivot axis do not coincide, spatial interference occurs between the second connecting arm 332, the second movable arm 331 (and the second support plate 24), and the second base 23. This spatial interference can only be resolved by rotating the second housing 20, such as the second main housing 21, and the second connecting component 33, such as the second connecting arm 332, around the second rotation axis, in conjunction with the sliding movement of the second base 23, such as the second slide rail 231, and the second connecting component 33, such as the second movable arm 331 (and the second support plate 24). The second connecting component 33, such as the second movable arm 331, and the second support plate 24 move away from the second housing 20, such as the second main housing 21.

[0102] Please refer to Figures 12 and 13. Figure 12 is a schematic diagram of a portion of the structure of the rotating shaft module 30 in the embodiment shown in Figure 2, and Figure 13 is an exploded view of a portion of the structure of the rotating shaft module 30 in the embodiment shown in Figure 12. The first sliding portion 3131, the second sliding portion 3132, the first pivoting portion 3141, and the second pivoting portion 3142 may be disposed on the base 311 rather than on the support plate 312.

The coordination between the first pivot portion 3141 and the first pivot end 3211 can refer to the coordination between the first sliding portion 3131 and the first sliding end 3221, and will not be further described. The first pivot portion 3141 or the first sliding portion 3131 can rotate about the first pivot axis.

The second pivot portion 3142 or the second sliding portion 3132 can rotate about the second pivot axis.

[0105] The first rotating portion 132 on the first base 13 may extend toward the side closest to the hinge module 30 and be rotatably connected to the support plate 312. When rotatably connected to the support plate 312, the support plate 312 can rotate about the first rotation axis, and the first connecting arm 322 may be omitted. In some embodiments, the first rotating portion 132 is located on the side of the support plate 312 away from the base 311. In some embodiments, the first rotating portion 132 is located on the side of the support plate 312 closer to the base 311.

[0107] In some embodiments, to reduce thickness, the first rotating portion 132 can be configured as a first sliding portion 3131, whereby the first rotating portion 132 extends in an arc. In some embodiments, the configuration of the first rotating portion 132 allows the support plate 312 to achieve a sliding connection when sliding in the direction of the first rotating portion 132, thereby rotating about the first rotation axis. For details on the configuration of the first rotating portion 132, see the first sliding portion 3131. Furthermore, in some embodiments, the first rotating portion 132 can be configured as a first sliding end 3221, for details on the configuration of the first sliding end 3221.

[0108] The second rotating portion 232 on the second base 23 may extend toward the side closest to the hinge module 30 and be rotatably connected to the support plate 312. When rotatably connected to the support plate 312, the support plate 312 can rotate about the second rotation axis. The second connecting arm 332 may be omitted. In some embodiments, the second rotating portion 232 is located on the side of the support plate 312 away from the base 311. In some embodiments, the second rotating portion 232 is located on the side of the support plate 312 closer to the base 311. In some embodiments, the second rotating portion 232 is located on the side of the support plate 312 closer to the base 311, or alternatively, on the side of the support plate 312. In some embodiments, the second rotation axis may be located on the side of the support plate 312 away from the base 311. In some embodiments, the second rotation axis may be located within the support plate 312. In some embodiments, the second rotation axis is closer to the base 311 than the second pivot axis. In some embodiments, the second rotation axis is farther from the first pivot axis than the second pivot axis. In some embodiments, the second rotation axis and the first rotation axis are equidistant from the display module 102. In some embodiments, the distance between the second rotation axis and the second pivot axis is the same as the distance between the first rotation axis and the first pivot axis. The plane containing the second rotation axis and the first rotation axis is parallel to the plane containing the first and second pivot axes. The midpoint of the shortest line connecting the second rotation axis and the first pivot axis and the midpoint of the shortest line connecting the first rotation axis and the second pivot axis can both lie on a straight line parallel to the second pivot axis. In some embodiments, the second rotation axis is farther from the base 311 than the second limiting axis. In some embodiments, the second rotation axis is farther from the first limiting axis than the second limiting axis. In some embodiments, the second rotation axis and the first rotation axis are each at the same distance from the display module 102. In some embodiments, the distance between the second rotation axis and the second limiting axis is the same as the distance between the first rotation axis and the first limiting axis. In some embodiments, the plane containing the second rotation axis and the first rotation axis is parallel to the plane containing the first and second limiting axes. In some embodiments, the midpoint of the shortest line connecting the second rotation axis and the first limiting axis and the midpoint of the shortest line connecting the first rotation axis and the second limiting axis can both lie on a straight line parallel to the second limiting axis. In some embodiments, the distance between the second rotation axis and the first rotation axis is greater than the distance between the first limiting axis and the second limiting axis.

[0109] In some embodiments, to reduce thickness, the second rotating portion 232 can be configured as a second sliding portion 3132, whereby the second rotating portion 232 extends in an arc. In some embodiments, the second rotating portion 232 allows the support plate 312 to achieve a sliding connection when sliding in the direction of the second rotating portion 232, and can rotate about a second rotation axis. For details on the configuration of the second rotating portion 232, see "Second Sliding Portion 3132." Furthermore, in some embodiments, the second rotating portion 232 can be configured as a second sliding end 3321, for details on the configuration of the second sliding end 3321.

[0110] In some embodiments, the support plate 312 may cover a portion of the base 311, so that the second pivoting portion 3142 and the first pivoting portion 3141 are exposed and directly engage with the first sliding portion 3131 and the second sliding portion 3132. In some embodiments, the support plate 312 may cover the first sliding portion 3131 and the second sliding portion 3132.

[0111] The support plate 312 may include a first sub-plate 3121 and a second sub-plate 3122 arranged side by side and respectively slidably connected to the base 311. The first sub-plate 3121 may be connected to the first base 13, such as the first rotating portion 132, and the second sub-plate 3122 may be connected to the second base 23, such as the second rotating portion 232.

[0112] The first sub-plate 3121 is provided with a first sub-connecting portion 3123 for sliding connection with the first sliding portion 3131. In some embodiments, the first sub-connecting portion 3123 extends in an arc. In some embodiments, the first sub-connecting portion 3123 is configured so that the first sliding portion 3131 can rotate about a first limiting axis when sliding in the direction of extension of the first sub-connecting portion 3123.

[0113] The first sub-plate 3121 is provided with a first sub-sliding portion 3124 for connection with the first base 13, such as the first rotating portion 132. In some embodiments, the first sub-sliding portion 3124 extends in an arc. The configuration of the first sub-sliding portion 3124 allows the first base 13, such as the first rotating portion 132, to rotate about a first rotation axis when sliding in the direction of the first sub-sliding portion 3124. In some embodiments, the first sub-sliding portion 3124 is located on a side of the first sub-plate 3121 away from the base 311.

[0114] The second sub-plate 3122 is provided with a second sub-connecting portion 3125 for sliding connection with the second sliding portion 3132. In some embodiments, the second sub-connecting portion 3125 extends in an arc. In some embodiments, the second sub-connecting portion 3125 is configured so that the second sliding portion 3132 can rotate about the second limiting axis when sliding in the direction of the second sub-connecting portion 3125.

[0115] The second sub-plate 3122 is provided with a second sub-sliding portion 3126 for connection with the second base 23, such as the second rotating portion 232.

[0118] As can be understood, based on Figures 12 and 13 , the hinge module 30 can support and mount the display module 102. Of course, in some embodiments, the first and second support plates 14, 24 can be modified or omitted. In some embodiments, the first and second support plates 14, 24 can also be designed, modified, or omitted according to the above-described embodiments. In some embodiments, the hinge module 30 can be adaptively modified in shape to support and mount the display module 102. In some embodiments, other structures can be added to the hinge module 30 to support and mount the display module 102. In some embodiments, the support plate 312 can support and mount the display module 102 together with the base 311, the first movable arm 321, and / or the second movable arm 331. In some embodiments, the support plate 312 can cooperate with the first and second support plates 14, 24 to support the display module 102. In some embodiments, the technical solution shown in Figures 1-11 can also adopt the embodiments shown in Figures 12-14 to design the rotating shaft bracket 31, the first connecting component 32, the second connecting component 33, the first support plate 14 and / or the second support plate 24.

[0119] Please refer to Figures 1, 12 to 14. Figure 14 is a schematic diagram of the partial structure of the electronic device 100 in the embodiment shown in Figure 1 when the hinge module 30 in Figure 12 is in a fully folded state. The content of how the hinge module 30 supports the display module 102 is omitted here (of course, you can also refer to the description in the above embodiment), and only how the hinge module 30 is folded or unfolded is explained. In Figure 1, the electronic device 100 is in a flattened state. When folding the electronic device 100, force can be applied to the first shell 10, such as the first main shell 11, and the second shell 20, such as the second main shell 21, so that the shell mechanism 101 bends toward the side close to the display module 102.

[0120] Furthermore, the first housing 10, such as the first main housing 11, is bent toward the side closest to the display module 102. When the first base 13, such as the first slide rail 131, and the first connecting component 32, such as the first movable arm 321, are limited to sliding but not rotating, the first housing 10, such as the first main housing 11, can only rotate through the first connecting component 32, such as the first movable arm 321, and the base 311, such as the first pivoting portion 3141, and rotates about the first pivot axis. Simultaneously, the first housing 10, such as the first main housing 11, can be engaged with the first base 13, such as the first rotating portion 132, and the first sub-plate 3121, such as the first sub-sliding portion 3124, and the first sub-plate 3121, such as the first sub-connecting portion 3123, can be engaged with the base 311, such as the first sliding portion 3131. For example, the first base 13, such as the first rotating portion 132, can rotate relative to the first sub-plate 3121, such as the first sub-sliding portion 3124, about the first rotation axis. For example, the first sub-plate 3121, for example, the first sub-sliding portion 3124, rotates about the first rotation axis relative to the first base 13, for example, the first rotating portion 132. For example, the first sub-plate 3121, for example, the first sub-connecting portion 3123, rotates about the first limiting axis relative to the base 311, for example, the first sliding portion 3131. For example, the base 311, for example, the first sliding portion 3131, rotates about the first limiting axis relative to the first sub-plate 3121, for example, the first sub-connecting portion 3123.

[0121] When the first pivot axis, the first rotation axis, and the first limiting axis do not coincide with each other, spatial interference occurs between the first sub-plate 3121, the first movable arm 321, and the first base 13. This spatial interference can be resolved by cooperating between the first base 13, such as the first rotating portion 132, and the first sub-plate 3121, such as the first sub-sliding portion 3124, and the first sub-plate 3121, such as the first sub-connecting portion 3123, and the base 311, such as the first sliding portion 3131, in conjunction with the sliding movement of the first base 13, such as the first slide rail 131, and the first connecting assembly 32, such as the first movable arm 321. The angle at which the first base 13, such as the first rotating portion 132 rotates about the first rotation axis relative to the first sub-plate 3121, such as the first sub-sliding portion 3124, is greater than the angle at which the first sub-plate 3121, such as the first sub-connecting portion 3123, rotates about the first limiting axis relative to the base 311, such as the first sliding portion 3131, thereby allowing the hinge module 30 to yield to the display module 102. The hinge bracket 31 is further thinned so that the display module 102 presents a "U" shape when the electronic device 100 is fully folded.

[0122] Furthermore, the second housing 20, such as the second main housing 21, is bent toward the side closest to the display module 102. When the second base 23, such as the second slide rail 231, and the second connecting assembly 33, such as the second movable arm 331, are limited to sliding but not rotating, the second housing 20, such as the second main housing 21, can only rotate through the second connecting assembly 33, such as the second movable arm 331, and the base 311, such as the second pivoting portion 3142, and rotates about the second pivot axis. Simultaneously, the second housing 20, such as the second main housing 21, can be engaged with the second base 23, such as the second rotating portion 232, and the second sub-plate 3122, such as the second sub-sliding portion 3126, and the second sub-plate 3122, such as the second sub-connecting portion 3125, and the base 311, such as the second sliding portion 3132. For example, the second base 23, such as the second rotating portion 232, can rotate relative to the second sub-plate 3122, such as the second sub-sliding portion 3126, about the second rotation axis. For example, the second sub-plate 3122, for example, the second sub-sliding portion 3126, rotates about the second rotation axis relative to the second base 23, for example, the second rotating portion 232. For example, the second sub-plate 3122, for example, the second sub-connecting portion 3125, rotates about the second limiting axis relative to the base 311, for example, the second sliding portion 3132. For example, the base 311, for example, the second sliding portion 3132, rotates about the second limiting axis relative to the second sub-plate 3122, for example, the second sub-connecting portion 3125.

[0123] When the second pivot axis, the second rotation axis, and the second limiting axis do not coincide with each other, spatial interference occurs between the second sub-plate 3122, the second movable arm 331, and the second base 23. This spatial interference can be resolved by cooperating between the second base 23, such as the second rotation portion 232, and the second sub-plate 3122, such as the second sub-sliding portion 3126, and cooperating between the second sub-plate 3122, such as the second sub-connecting portion 3125, and the base 311, such as the second sliding portion 3132. This, combined with the sliding movement of the second base 23, such as the second slide rail 231, and the second connecting assembly 33, such as the second movable arm 331, can resolve the spatial interference. The angle at which the second base 23, such as the second rotation portion 232, rotates about the second rotation axis relative to the second sub-plate 3122, such as the second sub-sliding portion 3126, is greater than the angle at which the second sub-plate 3122, such as the second sub-connecting portion 3125, rotates about the second limiting axis relative to the base 311, such as the second sliding portion 3132, thereby allowing the hinge module 30 to yield to the display module 102. The hinge bracket 31 is further thinned so that the display module 102 presents a "U" shape when the electronic device 100 is fully folded.
