Description

Technical Field

[0001] This application relates to the field of electronic equipment technology, and in particular to a rotating shaft mechanism and an electronic device. Background Technology

[0002] With the gradual maturation of flexible display technology, the way electronic devices display information has undergone tremendous changes. Foldable flexible screen mobile phones, foldable flexible screen tablets, and wearable electronic devices with foldable flexible screens represent a major direction for the evolution of future smart electronic devices.

[0003] The hinge mechanism, a crucial component for enabling the folding function of electronic devices, possesses the characteristic of continuous folding. Besides facilitating the transition between folded and unfolded states in foldable electronic devices, the hinge mechanism also provides sufficient support for the flexible display screen in different folding states. However, existing hinge mechanisms are structurally complex and offer relatively weak support for the flexible display screen, easily causing tension or compression, thus affecting the overall reliability of the electronic device. Summary of the Invention

[0004] This application provides a pivot mechanism and an electronic device to simplify the structure of the pivot mechanism and improve the support performance for flexible displays.

[0005] In a first aspect, this application provides a pivot mechanism. The pivot mechanism includes a base and at least one half-shaft module, wherein the half-shaft module includes a first connecting assembly and a second connecting assembly. Specifically, the first connecting assembly includes a first mounting plate, a first rotating member, a first connecting member, a second connecting member, and a first sliding member. The first mounting plate and the first rotating member are disposed on one side of the base. The first rotating member is slidably connected to the first mounting plate and rotatably connected to the base. The first connecting member is rotatably connected to the side of the first rotating member facing the base. The second connecting member is rotatably connected to the side of the first connecting member away from the first rotating member. The first sliding member is rotatably connected to the side of the second connecting member away from the first connecting member. Correspondingly, the second connecting assembly includes a second mounting plate, a second rotating member, a third connecting member, a fourth connecting member, and a second sliding member. The second mounting plate and the second rotating member are disposed on the side of the base away from the first mounting plate. The second rotating member is slidably connected to the second mounting plate and rotatably connected to the base. The third connecting member is rotatably connected to the side of the second rotating member facing the base. The fourth link is rotatably connected to the side of the third link away from the second rotating member. The second sliding member is rotatably connected to the side of the fourth link away from the third link. The second sliding member is fixedly connected to the first mounting plate, and the first sliding member is fixedly connected to the second mounting plate. When the pivot mechanism is applied to a foldable electronic device, the flexible display screen of the electronic device is disposed on one side of the pivot mechanism. Furthermore, the pivot mechanism also includes a first support rod and a second support rod. The first support rod is located between the first mounting plate and the base, and the half-shaft module and the base are rotatably connected to the first support rod. The second support rod is located between the second mounting plate and the base, and the half-shaft module and the base are rotatably connected to the second support rod. The first support rod has a first support surface on the side facing the flexible display screen, the second support rod has a second support surface on the side facing the flexible display screen, and the base has a third support surface on the side facing the flexible display screen.

[0006] When the electronic device is folded, the first and second mounting plates fold relative to each other. When the electronic device is unfolded, the first and second mounting plates unfold relative to each other. During the folding or unfolding process of the first and second mounting plates, the first rotating member rotates around the base and slides relative to the first mounting plate, and the second rotating member rotates around the base and slides relative to the second mounting plate. When the pivot mechanism is in the flattened state, the first, second, and third support surfaces can form a flat support surface for supporting the flexible display screen. When the pivot mechanism is in the folded state, the first, second, and third support surfaces can form a U-shaped support surface for supporting the flexible display screen. The above-mentioned pivot mechanism uses a chain assembly as the main rotation, which is simple in structure, and during folding and unfolding, the first and second support rods can provide better support for the flexible display screen, avoiding pulling or squeezing of the flexible display screen.

[0007] The first support rod is rotatably connected to the half-shaft module. Specifically, the side of the first support rod away from the base can be connected to the first mounting plate, or the side of the first support rod away from the base can be connected to the first rotating component, thus achieving relative movement between the first support rod and the half-shaft module. Similarly, the second support rod is rotatably connected to the half-shaft module. Specifically, the side of the second support rod away from the base can be connected to the second mounting plate, or the side of the second support rod away from the base can be connected to the second rotating component, thus achieving relative movement between the second support rod and the half-shaft module.

A first arc-shaped guide groove is provided on the side of the base facing the first support rod, and the first arc arm is housed within the first arc-shaped guide groove. The first support rod is rotatably connected to the base by sliding within the first arc-shaped guide groove. In one possible implementation, the first support rod is connected to the first mounting plate. Specifically, a second arc-shaped guide groove is provided on the side of the first mounting plate facing the first support rod, and the first pin is housed within the second arc-shaped guide groove.

In another possible implementation, the first support rod is connected to a first rotating component. Specifically, a second arc-shaped guide groove is provided on the side of the first rotating component facing the first support rod, and the first pin is housed within the second arc-shaped guide groove.

A fourth arc-shaped guide groove is provided on the side of the second mounting plate facing the second support rod, and the second pin is accommodated within the fourth arc-shaped guide groove, achieving relative movement between the second support rod and the second mounting plate through sliding within the fourth arc-shaped guide groove. In another possible implementation, the second support rod is connected to the second rotating member. A fourth arc-shaped guide groove is provided on the side of the second rotating member facing the second support rod, and the second pin is accommodated within the fourth arc-shaped guide groove, achieving relative movement between the second support rod and the second rotating member through sliding within the fourth arc-shaped guide groove.

[0009] Specifically, in the configuration of the first rotating component, a third arc arm is provided on the side of the first rotating component facing the base, and a fifth arc-shaped guide groove is provided on the side of the base facing the first rotating component. The third arc arm is housed within the fifth arc-shaped guide groove, and the rotational connection between the first rotating component and the base is achieved through sliding within the fifth arc-shaped guide groove. Similarly, a fourth arc arm is provided on the side of the second rotating component facing the base, and a sixth arc-shaped guide groove is provided on the side of the base facing the second rotating component. The fourth arc arm is housed within the sixth arc-shaped guide groove, and the rotational connection between the second rotating component and the base is achieved through sliding within the sixth arc-shaped guide groove.

[0010] In one possible implementation, the third arc arm has a first notch, and the fourth arc arm has a second notch. The first rotating member has a first end rotatably connected to the first connecting member, and the first end is located within the second notch. The second rotating member has a second end rotatably connected to the third connecting member, and the second end is located within the first notch, so that the first and second rotating members can be staggered, further reducing the overall size of the half-shaft module.

[0090] To make the objectives, technical solutions, and advantages of this application clearer, the application will now be described in further detail with reference to the accompanying drawings.

[0091] It should be noted that the terminology used in the following embodiments is for the purpose of describing specific embodiments only and is not intended to be a limitation of this application. As used in the specification and appended claims of this application, the singular expressions “a,” “an,” “the,” “the,” “the,” and “this” are intended to also include expressions such as “one or more,” unless the context clearly indicates otherwise.

[0092] References to "one embodiment" or "some embodiments" as described in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0093] To facilitate understanding of the hinge mechanism provided in this application embodiment, its application scenarios are described below. This hinge mechanism can be applied to, but is not limited to, foldable electronic devices such as mobile phones, smart wearable devices, tablets, or laptops. When applying the hinge mechanism provided in this application embodiment to electronic devices, please refer to... Figure 1 , Figure 1 This is a schematic diagram of an electronic device provided in an embodiment of this application. The electronic device 10 provided in this application is an outward-folding electronic device. Figure 1 As shown, in addition to the pivot mechanism 11, the electronic device 10 may also include a flexible display screen 12, a first housing 13, and a second housing 14. The flexible display screen 12 continuously covers the pivot mechanism 11, the first housing 13, and the second housing 14, and the first housing 13 and the second housing 14 are respectively fixedly connected to the flexible display screen 12. Figure 2 A schematic diagram showing the electronic device provided in an embodiment of this application in a flattened state. Figure 3 for Figure 2 Exploded view of electronic equipment in China Figure 4 This is a schematic diagram of an electronic device provided in an embodiment of this application in a folded state. Figure 5 for Figure 4 Exploded view of electronic equipment in China. (Example) Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, specifically, the first housing 13 and the second housing 14 are disposed on both sides of the rotating shaft mechanism 11 and can rotate around the rotating shaft mechanism 11. When using the electronic device 10, it can be folded and unfolded according to different usage scenarios. For example... Figure 2 and Figure 3 As shown, when the electronic device 10 is in a flattened state, the flexible display screen 12 is located on the same side of the pivot mechanism 11, the first housing 13, and the second housing 14. At this time, the outer surface of the first housing 13 away from the flexible display screen 12, the outer surface of the pivot mechanism 11 away from the flexible display screen 12, and the outer surface of the second housing 14 away from the flexible display screen 12 can collectively serve as the external surface of the electronic device 10. Figure 4 and Figure 5 As shown, when the electronic device 10 is in a folded state, the first housing 13 and the second housing 14 are positioned opposite each other. The flexible display screen 12 can serve as both the display surface and the exterior surface of the electronic device 10. It can be understood that the process of the electronic device 10 changing from a flattened state to a folded state, or vice versa, is the process of the first housing 13 and the second housing 14 rotating around the pivot mechanism 11. During this process, the flexible display screen 12 bends or flattens along with the first housing 13 and the second housing 14.

[0094] In some current foldable electronic devices, the hinge mechanism has a relatively complex structure, high manufacturing cost, and poor performance in supporting flexible displays. Therefore, this application provides a hinge mechanism and electronic device to simplify the structure of the hinge mechanism and improve its support performance for flexible displays.

The first connecting component 1121 and the second connecting component 1122 are respectively connected to the base 111. Furthermore, the half-shaft module 112 may also include a synchronization component 1123, a first damping component 1124, and a second damping component 1125. The synchronization component 1123 is used to synchronize the rotation of the first connecting component 1121 and the second connecting component 1122. The first damping component 1124 and the second damping component 1125 provide torque during the rotation of the shaft mechanism 11 to ensure stable rotation of the shaft mechanism 11. In one embodiment, the base 111 may specifically include a main outer shaft 111a and a main inner shaft 111b. The main outer shaft 111a is located on the side of the main inner shaft 111b facing the flexible display screen 12, and the main outer shaft 111a is fixedly connected to the main inner shaft 111b. Specifically, the outer main shaft 111a and the inner main shaft 111b can be connected by means of bonding, threaded connection or welding, etc., and this application does not impose specific restrictions.

[0105] Figure 25 This is a partial schematic diagram of the base provided in an embodiment of this application. Figure 26This is a schematic diagram illustrating the cooperation between the first rotating member, the second rotating member, and the base, as provided in an embodiment of this application. Figure 25 and Figure 26 As shown, a fifth arc-shaped guide groove 1113 is provided on the side of the base 111 facing the first rotating member 11212. A third arc arm 112121 is housed within the fifth arc-shaped guide groove 1113, and the first rotating member 11212 is rotatably connected to the base 111 by sliding the third arc arm 112121 within the fifth arc-shaped guide groove 1113. A sixth arc-shaped guide groove 1114 is provided on the side of the base 111 facing the second rotating member 11222. A fourth arc arm 112221 is housed within the sixth arc-shaped guide groove 1114, and the second rotating member 11222 is rotatably connected to the base 111 by sliding the fourth arc arm 112221 within the sixth arc-shaped guide groove 1114.

[0106] like Figure 16 and Figure 17 As shown, the third arc arm 112121 has a first notch 112122, and the first rotating member 11212 has a first end 11212a that is rotatably connected to the first connecting member 11213. Figure 20 and Figure 21 As shown, the fourth arc arm 112221 has a second notch 112222, and the second rotating member 11222 has a second end 11222a that is rotatably connected to the third connecting member 11223.

Figure 29 Another schematic diagram showing the cooperation between the fourth, fifth, and sixth pins and the first limiting groove and the second sliding groove, as provided in the embodiments of this application. Figure 27 For electronic devices to be in a flattened state, Figure 28 The electronic device is in a semi-folded state. Figure 29 The electronic device is in a folded state. For example... Figure 27 , Figure 28 and Figure 29As shown, the fourth pin 11226, the fifth pin 11227, and the sixth pin 11228 are at least partially accommodated within the first limiting groove 112123 and slide along the first limiting groove 112123. Specifically, in the flattened state, the fourth pin 11226 can be located within the first limiting groove 112123, while the fifth pin 11227 and the sixth pin 11228 are located within the second sliding groove 112124. During folding, the fourth pin 11226 gradually disengages from the first limiting groove 112123, and the fifth pin 11227 and the sixth pin 11228 move towards the first limiting groove 112123. Similarly, the first pin 11216, the second pin 11217, and the third pin 11218 are at least partially accommodated within the second limiting groove 112223 and slide along the second limiting groove 112223, which will not be elaborated here.

[0107] Figure 30 This is a schematic diagram illustrating the movement of the first link component from a flattened state to a folded state, as provided in an embodiment of this application. Figure 30 The cross-section shown is Figure 7 A cross-sectional view along the BB direction, (a) shows the flattened state, (b) shows the semi-folded state (between the flattened and folded states), and (c) shows the folded state. Figure 30 As shown, when the first mounting plate 11211 and the second mounting plate 11221 are folded or unfolded relative to each other, the first rotating member 11212 rotates around the base 111 and slides relative to the first mounting plate 11211. When the first mounting plate 11211 and the second mounting plate 11221 change from a flattened state to a folded state, the first rotating member 11212 rotates around the base 111 in a direction toward the second mounting plate 11221 (e.g., ...). Figure 30 The first rotating member 11212 rotates counterclockwise (in the direction of rotation). During this process, the first rotating member 11212 drives the first connecting member 11213, the second connecting member 11214, and the first sliding member 11215 to move in the direction toward the first mounting plate 11211. Since the first sliding member 11215 is fixedly connected to the second mounting plate 11221, the second mounting plate 11221 moves with the first sliding member 11215 in the direction toward the base 111. When the first mounting plate 11211 and the second mounting plate 11221 change from a folded state to a flattened state, the first rotating member 11212 rotates around the base 111 in a direction away from the second mounting plate 11221 (e.g., counterclockwise). Figure 30 The first rotating component 11212 rotates clockwise. During this process, the first connecting component 11213, the second connecting component 11214, and the first sliding component 11215 move in a direction away from the first mounting plate 11211. Since the first sliding component 11215 is fixedly connected to the second mounting plate 11221, the second mounting plate 11221 follows the first sliding component 11215 in a direction away from the base 111. Figure 31This is a schematic diagram illustrating the movement of the second link component from a flattened state to a folded state, as provided in an embodiment of this application. Figure 31 The cross-section shown is Figure 7 A cross-sectional view along the CC direction, (a) showing the flattened state, (b) showing the semi-folded state (between the flattened and folded states), and (c) showing the folded state. Figure 31 As shown, when the first mounting plate 11211 and the second mounting plate 11221 are folded or unfolded relative to each other, the second rotating member 11222 rotates around the base 111 and slides relative to the second mounting plate 11221. When the first mounting plate 11211 and the second mounting plate 11221 change from a flattened state to a folded state, the second rotating member 11222 rotates around the base 111 in a direction toward the first mounting plate 11211 (e.g., ...). Figure 31 The second rotating member 11222 rotates clockwise. During this process, the third connecting member 11223, the fourth connecting member 11224, and the second sliding member 11225 move in the direction toward the second mounting plate 11221. Since the second sliding member 11225 is fixedly connected to the first mounting plate 11211, the first mounting plate 11211 moves with the second sliding member 11225 in the direction toward the base 111. When the first mounting plate 11211 and the second mounting plate 11221 change from a folded state to a flattened state, the second rotating member 11222 rotates around the base 111 in a direction away from the first mounting plate 11211 (e.g., clockwise). Figure 31 The rotating mechanism 11 rotates counterclockwise. During this process, the second rotating component 11222 drives the third connecting component 11223, the fourth connecting component 11224, and the second sliding component 11225 to move away from the second mounting plate 11221. Since the second sliding component 11225 is fixedly connected to the first mounting plate 11211, the first mounting plate 11211 follows the second sliding component 11225 to move away from the base 111. Therefore, the flattening and folding of the rotating shaft mechanism 11 can be achieved through the first connecting component 1121 and the second connecting component 1122. This structure is simple and has a low manufacturing cost.

[0108] like Figure 8As shown, the rotating shaft mechanism 11 also includes a first support rod 113 and a second support rod 114. The first support rod 113 is located between the first mounting plate 11211 and the base 111, and is positioned close to the flexible display screen 12. The first support rod 113 is rotatably connected to both the half-shaft module 112 and the base 111. The second support rod 114 is located between the second mounting plate 11221 and the base 111, and is positioned close to the flexible display screen 12. The second support rod 114 is rotatably connected to both the half-shaft module 112 and the base 111. The side of the first support rod 113 facing the flexible display screen 12 has a first support surface S1, the side of the second support rod 114 facing the flexible display screen 12 has a second support surface S2, and the side of the base 111 facing the flexible display screen 12 has a third support surface S3. Figure 32 This is a schematic diagram of the half-shaft module provided in an embodiment of this application in its unfolded state. Figure 32 As shown, when the pivot mechanism 11 is in a flattened state, the first support surface S1, the second support surface S2 and the third support surface S3 form a flat support surface for supporting the flexible display screen 12. Figure 33 This is a schematic diagram of the half-shaft module provided in an embodiment of this application in a folded state. Figure 33 As shown, when the pivot mechanism 11 is in the folded state, the first support surface, the second support surface, and the third support surface form a U-shaped support surface for supporting the flexible display screen 12. It should be noted that the third support surface S3 refers to the outer surface of the base 111. For example, in one embodiment, the outer surface of the main outer shaft 111a facing the flexible display screen 12 can be the third support surface S3.

[0109] Figure 34 This is a schematic diagram of a first support rod provided in an embodiment of this application. Figure 34 As shown, the side of the first support rod 113 away from the base 111 can be connected to the first mounting plate 11211. Specifically, the side of the first support rod 113 facing the base 111 is provided with a first arc arm 1131, and the side of the first support rod 113 facing the first mounting plate 11211 is provided with a first pin 1132. Figure 35 This is a schematic diagram of the rotating shaft mechanism provided in the embodiment of this application in a flattened state. Figure 36 This is a schematic diagram of the rotating shaft mechanism provided in an embodiment of this application in a folded state. Figure 35 and Figure 36As shown, a first arc-shaped guide groove 1111 is provided on the side of the base 111 facing the first support rod 113. A first arc arm 1131 is housed within the first arc-shaped guide groove 1111, and the first support rod 113 is rotatably connected to the base 111 by sliding the first arc arm 1131 within the first arc-shaped guide groove 1111. A second arc-shaped guide groove 112111 is provided on the side of the first mounting plate 11211 facing the first support rod 113. A first pin 1132 is housed within the second arc-shaped guide groove 112111, and the relative movement between the first support rod 113 and the first mounting plate 11211 is achieved by sliding the first pin 1132 within the second arc-shaped guide groove 112111.

[0110] Figure 37 This is a schematic diagram of the second support rod provided in an embodiment of this application. Figure 37 As shown, the side of the second support rod 114 away from the base 111 can be connected to the second mounting plate 11221. Specifically, the side of the second support rod 114 facing the base 111 is provided with a second arc arm 1141, and the side of the second support rod 114 facing the second mounting plate 11221 is provided with a second pin 1142. Figure 38 Another schematic diagram showing the rotating shaft mechanism provided in the embodiments of this application in a flattened state. Figure 39 Another schematic diagram showing the rotating shaft mechanism provided in the embodiment of this application in a folded state. (See diagram below.) Figure 38 and Figure 39 As shown, a third arc-shaped guide groove 1112 is provided on the side of the base 111 facing the second support rod 114. The second arc arm 1141 is housed within the third arc-shaped guide groove 1112, and the second support rod 114 is rotatably connected to the base 111 by sliding the second arc arm 1141 within the third arc-shaped guide groove 1112. A fourth arc-shaped guide groove 112211 is provided on the side of the second mounting plate 11221 facing the second support rod 114. The second pin 1142 is housed within the fourth arc-shaped guide groove 112211, and the relative movement between the second support rod 114 and the second mounting plate 11221 is achieved by sliding the second pin 1142 within the fourth arc-shaped guide groove 112211.

[0111] In another embodiment, the side of the first support rod 113 away from the base 111 can be connected to the first rotating member 11212. A second arc-shaped guide groove 112111 can be provided on the side of the first rotating member 11212 facing the first support rod 113. The first pin 1132 is accommodated within the second arc-shaped guide groove 112111, and the relative movement between the first support rod 113 and the first rotating member 11212 is achieved by sliding the first pin 1132 within the second arc-shaped guide groove 112111. Similarly, the side of the second support rod 114 away from the base 111 can be connected to the second rotating member 11222. The fourth arc-shaped guide groove 112211 can be set on the side of the second rotating member 11222 facing the second support rod 114. The second pin 1142 is accommodated in the fourth arc-shaped guide groove 112211, and the relative movement between the second support rod 114 and the second rotating member 11222 is realized by the sliding of the second pin 1142 in the fourth arc-shaped guide groove 112211.

[0112] In another embodiment of this application, the first support rod 113 and the second support rod 114 described above can be omitted. In this embodiment, a first support piece is provided on the side of the flexible display screen 12 facing the first housing 13, and the side of the first support piece away from the base 111 is fixedly connected to the flexible display screen 12. A second support piece is provided on the side of the flexible display screen 12 facing the second housing 14, and the side of the second support piece away from the base 111 is fixedly connected to the flexible display screen 12. The first support piece and the second support piece are used together to support the flexible display screen 12.

[0113] Figure 40 A schematic diagram of the synchronization component provided in an embodiment of this application. Figure 41 This is a schematic diagram of a first gear slider and a second gear slider provided in an embodiment of this application. Figure 40 and Figure 41As shown, the synchronization component 1123 includes a first rotating shaft 11231, a second rotating shaft 11232, a first gear slider 11233, and a second gear slider 11234. Specifically, the first rotating shaft 11231 and the second rotating shaft 11232 are arranged parallel to each other on the base 111. The first rotating shaft 11231 is located close to the first mounting plate 11211. The first gear slider 11233 includes a first slider body 112331 and a first tooth 112332. The first tooth 112332 is sleeved on the periphery of the first rotating shaft 11231, and the first tooth 112332 and the first rotating shaft 11231 are rotatably connected. The first slider body 112331 is located on the side of the first tooth 112332 away from the base 111, and the first slider body 112331 is slidably connected to the first mounting plate 11211. Similarly, the second gear slider 11234 includes a second slider body 112341 and a second tooth 112342. The second tooth 112342 is sleeved on the circumference of the second rotating shaft 11232 and is rotatably connected to the second rotating shaft 11232. The first tooth 112332 and the second tooth 112342 mesh. The second slider body 112341 is located on the side of the second tooth 112342 away from the base 111, and the second slider body 112341 is slidably connected to the second mounting plate 11221. When the first mounting plate and the second mounting plate 11221 are folded or unfolded relative to each other, the first slider body 112331 slides relative to the first mounting plate 11211, and the second slider body 112341 slides relative to the second mounting plate 11221. Because the first tooth 112332 and the second tooth 112342 mesh, the first tooth 112332 and the second tooth 112342 rotate synchronously. That is, the rotation angle and rotation speed of the first tooth 112332 and the second tooth 112342 are the same, so that the sliding amount of the first slider body 112331 relative to the first mounting plate 11211 is equal to the sliding amount of the second slider body 112341 relative to the second mounting plate 11221, thereby making the first mounting plate 11211 and the second mounting plate 11221 rotate synchronously relative to the base 111.

[0114] In embodiments of this application, the first damping component 1124 and the second damping component 1125 are used to provide torque to the first connecting component 1121 and the second connecting component 1122 to stabilize the rotation of the shaft mechanism 11. The first damping component 1124 is disposed on the first mounting plate 11211, and the second damping component 1125 is disposed on the second mounting plate 11221. The structures of the first damping component 1124 and the second damping component 1125 are similar. Figure 42 This is a schematic diagram illustrating the mating of the first damping component and the first mounting plate provided in an embodiment of this application. Figure 43 This is a schematic diagram of a first damping component provided in an embodiment of this application. Figure 42 and Figure 43 As shown, taking the first damping assembly 1124 as an example, the first damping assembly 1124 includes a first bracket 11241 and a first spring 11242. A first mounting plate 11211 is provided with a first frame 112113. The first frame 112113 and the first bracket 11241 can enclose and form an accommodating space, within which the first spring 11242 is disposed. Furthermore, the first frame 112113 is slidably connected to the first bracket 11241. The first bracket 11241 has a first protrusion 112411. (The text repeats itself here.) Figure 17 As shown, the first rotating member 11212 has a second protrusion 112125. The first protrusion 112411 can abut against the second protrusion 112125. Figure 44 This is a schematic diagram illustrating the engagement of the first damping component and the first mounting plate in a flattened state, as provided in an embodiment of this application. Figure 44 As shown, in the flattened state, the first protrusion 112411 abuts against the second protrusion 112125, and there is no interaction force between the first protrusion 112411 and the second protrusion 112125. Figure 45 This is a schematic diagram illustrating the engagement of the first damping component and the first mounting plate in a semi-folded state, as provided in an embodiment of this application. Figure 45 As shown, during the folding process, the second protrusion 112125 slides along the direction away from the base 111 with the first rotating member 11212, and at the same time pushes the first protrusion 112411, thereby causing the first bracket 11241 to move relative to the first frame 112113, thereby compressing the first spring 11242 and realizing the damping effect of the first damping component 1124. Figure 46 This is a schematic diagram illustrating the engagement of the first damping component and the first mounting plate in a folded state, as provided in an embodiment of this application. Figure 46 As shown, after further folding, the second protrusion 112125 separates from the first protrusion 112411, and the first protrusion 112411 returns to its original position (i.e., the position in the flattened state) under the elastic force of the first spring 11242, until the folded state.

Figure 48 This is a schematic diagram of the half-shaft module provided in an embodiment of this application in a semi-folded state. Figure 49 Another schematic diagram showing the half-shaft module provided in this application embodiment in a folded state. (See diagram below.) Figure 47 , Figure 48 and Figure 49As shown, the pivot mechanism 11 also includes a first door panel 115 and a second door panel 116. The first door panel 115 is fixedly connected to the side of the first rotating member 11212 away from the flexible display screen 12, and the second door panel 116 is fixedly connected to the side of the second rotating member 11222 away from the flexible display screen 12. Therefore, during the folding or unfolding of the pivot mechanism 11, the first door panel 115 slides relative to the first mounting plate 11211 with the first rotating member 11212, and the second door panel 116 slides relative to the second mounting plate 11221 with the second rotating member 11222. When the pivot mechanism 11 is in a flattened state, the first door panel 115 and the second door panel 116 can shield the first connecting assembly 1121 and the second connecting assembly 1122.
