Abstract

This application provides a hinge mechanism and an electronic device. The hinge mechanism includes a first housing, a second housing, a rotating module, and a shielding module. The first housing and the second housing are located on opposite sides of the rotating module. The first housing has a protrusion, and the second housing has a groove. The shielding module includes a shielding slider and a reset assembly. The shielding slider slides within the groove along the thickness direction of the second housing. The reset assembly includes a reset slider and a reset spring. The reset slider abuts against the shielding slider and is slidably connected to the second housing. The sliding direction of the reset slider is not parallel to the sliding direction of the shielding slider. The reset spring is located between the reset slider and the second housing. When folding the electronic device, the protrusion pushes the shielding slider within the groove to slide, allowing the protrusion to be accommodated in the groove.

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] As foldable electronic devices become increasingly thinner and lighter, the thickness of some components has exceeded the thickness of the main body, resulting in a protrusion on one side of the frame and an uneven appearance. To avoid this protrusion when the device is folded, a groove is designed on the other side of the frame, allowing the protrusion to be accommodated and enabling seamless folding. However, when the device is unfolded, the groove on the frame detracts from the overall aesthetics, and foreign objects can easily fall into it, affecting the user experience. Summary of the Invention

[0004] This application provides a pivot mechanism and an electronic device to cover a groove when the electronic device is in the unfolded state, thereby preventing dust and other particles from falling into the groove and improving the aesthetics of the electronic device.

[0005] In a first aspect, this application provides a rotating shaft mechanism. The rotating shaft mechanism includes a rotating module, a first housing, a second housing, and a shielding module. Specifically, the first housing and the second housing are disposed opposite to each other on both sides of the rotating module, and are rotatably connected to the rotating module. A protrusion is provided on the side of the first housing away from the rotating module, and a groove is provided on the side of the second housing away from the rotating module; the protrusion and the groove are symmetrically arranged relative to the rotating module. The shielding module includes a shielding slider and at least one reset component. The shielding slider is at least partially accommodated within the groove, and is capable of sliding within the groove along the thickness direction of the second housing. The reset component includes a reset slider and a reset spring; the reset slider is disposed on one side of the shielding slider and abuts against the shielding slider. The reset slider is slidably connected to the second housing, and the sliding direction of the reset slider is not parallel to the sliding direction of the shielding slider. The reset spring is connected between the reset slider and the second housing.

[0006] The aforementioned hinge mechanism is applied to foldable electronic devices. When the first and second housings are folded relative to each other, the protrusion moves toward the groove, and the protrusion pushes the shielding slider to slide within the groove in a first direction away from the first housing, thereby pushing the reset slider to slide relative to the second housing, and simultaneously compressing the reset spring so that the protrusion is accommodated in the groove. When the first and second housings are unfolded relative to each other, the reset spring applies a reset force to the reset slider, causing the reset slider to slide relative to the second housing, and pushing the shielding slider to slide within the groove in a direction opposite to the first direction, so that the shielding slider covers the groove. Therefore, when the electronic device is folded, the protrusion pushes the shielding slider to the end of the groove away from the first housing, so that the protrusion is accommodated in the groove. When the electronic device is unfolded, the protrusion disengages from the groove, and the shielding slider slides to the end of the groove facing the first housing under the action of the reset component, so that the shielding slider can cover the groove to prevent dust and other particles from falling into the groove and improve the aesthetics of the electronic device.

[0007] When specifically configuring the sliding connection between the shielding slide groove and the groove, a limiting slide groove is provided on the inner wall of the groove, which extends along the thickness direction of the second housing. The shielding slider includes a slider body and a limiting protrusion, with the limiting protrusion located on the side of the slider body facing the limiting slide groove. The limiting protrusion is accommodated within the limiting slide groove, and the sliding connection between the shielding slider and the groove is achieved by the limiting protrusion sliding within the limiting slide groove.

[0008] In one possible implementation, the shielding slider has a contact surface that abuts against the reset slider, and this contact surface is not parallel to the sliding direction of the reset slider. When the protrusion pushes the shielding slider to slide within the groove, or when the reset slider pushes the shielding slider to slide within the groove, the contact point between the reset slider and the shielding slider moves along the contact surface, thereby causing the reset slider and the shielding slider to move along their respective sliding directions.

[0009] The number of the at least one reset component is not limited. In one possible implementation, the shielding module may include one reset component. This reset component is located on one side of the shielding slider. In another possible implementation, the shielding module may include a first reset component and a second reset component. The first reset component includes a first reset slider and a first reset spring, and the second reset component includes a second reset slider and a second reset spring. The first reset slider and the second reset slider are disposed opposite to each other on both sides of the shielding slider and abut against the shielding slider, respectively. The sliding direction of the first reset slider is opposite to the sliding direction of the second reset slider and is perpendicular to the sliding direction of the shielding slider. One end of the first reset spring is connected to the end of the first reset slider away from the shielding slider, and the other end is connected to the second housing. One end of the second reset spring is connected to the end of the second reset slider away from the shielding slider, and the other end is connected to the second housing.

[0010] When the at least one reset component is specifically configured, the second housing may be provided with a receiving groove, which can communicate with the recess, and the extending direction of the receiving groove is the same as the sliding direction of the reset slider. The at least one reset component can be accommodated in the receiving groove. Specifically, a fixing post is provided on the inner wall of the receiving groove at the end away from the recess. The reset slider is positioned close to the recess. One end of the reset spring is connected to the end of the reset slider away from the recess, and the other end is sleeved on the fixing post. In this implementation, the reset component is detachably connected to the second housing to facilitate the assembly and disassembly of the shielding module.

[0011] In one possible implementation, the first housing has a snap-fit ​​edge for engaging with the second housing. Specifically, a protrusion is provided on the snap-fit ​​edge. The shielding module also includes a baffle, which is disposed opposite to the snap-fit ​​edge relative to the base, and the baffle is rotatably connected to the second housing. When the first and second housings are folded relative to each other, the snap-fit ​​edge abuts against the baffle and pushes the baffle to rotate, so that the shielding module avoids the snap-fit ​​edge. When the first and second housings are unfolded relative to each other, the reset slider slides relative to the second housing and pushes the baffle to rotate, so that the baffle shields the reset assembly, improving the aesthetics of the electronic device when unfolded.

[0012] In one possible implementation, the end of the reset slider away from the shielding slider has an inclined surface that abuts against the baffle. The inclined surface is not parallel to the sliding direction of the reset slider, and it is also not parallel to the plane of rotation of the baffle. When the reset slider slides relative to the second housing, the contact point between the baffle and the reset slider moves along the inclined surface, thereby enabling the reset slider to push the baffle to rotate while sliding in the sliding direction.

[0013] In one possible implementation, the second housing has a limiting portion extending toward the baffle on the side near the baffle. The limiting portion is used to limit the rotation angle of the baffle to prevent the baffle from rotating excessively.

[0014] Secondly, this application provides an electronic device. The electronic device includes a flexible display screen and the pivot mechanism described in the first aspect, wherein the flexible display screen continuously covers one side of the pivot mechanism and is fixedly connected to the pivot mechanism.

[0015] When the electronic device is folded, the protrusion pushes the shielding slider to the end of the groove away from the first housing, allowing the protrusion to be accommodated within the groove. When the electronic device is unfolded, the protrusion disengages from the groove, and the shielding slider slides to the end of the groove facing the first housing under the action of the reset component, allowing the shielding slider to cover the groove and improve the aesthetics of the electronic device.

[0016] The aforementioned electronic device can be an outward-folding electronic device, specifically, the protrusion is located on the side of the first housing opposite to the flexible display screen, and the groove is located on the side of the second housing opposite to the flexible display screen. Alternatively, the electronic device can be an inward-folding electronic device, specifically, the protrusion is located on the side of the first housing facing the flexible display screen, and the groove is located on the side of the second housing facing the flexible display screen.

[0086] 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.

[0087] 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 and Figure 2 , Figure 1 A schematic diagram of an electronic device provided in an embodiment of this application. Figure 2 This is an exploded view of the electronic device provided in an embodiment of this application. The electronic device 10 provided in this application can be an outward-folding electronic device or an inward-folding electronic device.

[0088] like Figure 1 and Figure 2As shown, the electronic device 10 includes a pivot mechanism 11 and a flexible display screen 12. The pivot mechanism 11 includes a rotating module 110, a first housing 111, and a second housing 112. Specifically, the first housing 111 and the second housing 112 are disposed on both sides of the rotating module 110, and are rotatably connected to the rotating module 110, thereby enabling the folding and unfolding of the first housing 111 and the second housing 112 through the rotating module 110. The flexible display screen 12 is located on one side of the pivot mechanism 11 and covers the pivot mechanism 11.

[0089] When using this electronic device 10, it can be folded and unfolded according to different usage scenarios. For example, an outward-folding electronic device... Figure 1 As shown, when the electronic device 10 is in a folded state, the first housing 111 and the second housing 112 are positioned opposite each other. At this time, the flexible display screen 12 can serve as both the display surface and the exterior surface of the electronic device 10. Figure 2 As shown, when the electronic device 10 is in the unfolded state, the flexible display screen 12 is located on the same side of the rotating module 110, the first housing 111, and the second housing 112. At this time, the flexible display screen 12 serves as the display surface of the electronic device 10, and the outer surfaces of the first housing 111 and the second housing 112, which are opposite to the outer surfaces of the flexible display screen 12, together form the outer surface of the electronic device 10. Of course, the electronic device 10 can also be an inward-folding electronic device. When the electronic device 10 is in the folded state, the first housing 111, the second housing 112, and the rotating module 110 can form an accommodating space, which is teardrop-shaped. The bent portion of the flexible display screen 12 can be accommodated within this accommodating space to avoid pulling or squeezing the flexible display screen 12, thereby reducing the risk of damage to the flexible display screen 12.

[0090] It is understandable that the process of the electronic device 10 changing from an unfolded state to a folded state, or from a folded state to an unfolded state, is the process of the first housing 111 and the second housing 112 rotating around the rotating module 110. During this process, the flexible display screen 12 bends or flattens along with the first housing 111 and the second housing 112.

[0091] In some current foldable electronic devices, the middle frame of the first housing has a protrusion, and the middle frame of the second housing has a groove corresponding to the protrusion. When the electronic device is folded, the protrusion is accommodated within the groove, achieving a seamless fold. However, when the electronic device is unfolded, the groove is exposed to the air, making it easy for external dust, water droplets, and other small particles to fall in, affecting the functionality of the electronic device and also impacting the aesthetics of the overall structure.

[0092] Therefore, this application provides a pivot mechanism and an electronic device to cover the groove when the electronic device is in the unfolded state, thereby preventing dust and other particles from falling into the groove and improving the aesthetics of the electronic device.

[0093] 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.

[0094] 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.

[0095] The following is a detailed description of the electronic device provided in this application, which is an outward-folding electronic device.

[0096] Figure 3 This is a schematic diagram of the rotating shaft mechanism provided in an embodiment of this application in a folded state. Figure 4 This is a schematic diagram of the rotating shaft mechanism provided in an embodiment of this application in its deployed state. Figure 3 and Figure 4 As shown, the rotating shaft mechanism 11 includes a rotating module 110, a first housing 111, a second housing 112, and a shielding module 113. Specifically, the first housing 111 and the second housing 112 are symmetrically arranged on both sides of the rotating module 110, and the first housing 111 and the second housing 112 are rotatably connected to the rotating module 110.

[0097] Figure 5 This is a schematic diagram of a first housing provided for an embodiment of this application. Figure 5As shown, one side of the first housing 111 is rotatably connected to the rotating module 110, and a protrusion 1111 is provided on the side of the first housing 111 away from the rotating module 110. It should be noted that the protrusion 1111 in this embodiment can be a locking member, used to cooperate with the locking member of the second housing 112 to keep the rotating shaft mechanism 11 in a folded state; or, the protrusion 1111 can also be a protrusion of the first housing 111, which is caused by the thickness of a local component inside the electronic device 10 exceeding the thickness of the whole device.

[0098] Figure 6 A schematic diagram of the second housing provided in an embodiment of this application. Figure 7 An exploded view of the second housing provided in an embodiment of this application. (See attached image.) Figure 6 and Figure 7 As shown, one side of the second housing 112 is rotatably connected to the rotating module 110, and a groove 1121 is provided on the side of the second housing 112 away from the rotating module 110. The protrusion 1111 and the groove 1121 are symmetrically arranged relative to the rotating module 110. When the first housing 111 and the second housing 112 are folded relative to each other, the protrusion 1111 moves toward the groove 1121 and is accommodated within the groove 1121. A receiving slot 1120 is provided on the side of the second housing 112 away from the rotating module 110, and the receiving slot 1120 communicates with the groove 1121. A shielding module 113 is disposed within the receiving slot 1120 and the groove 1121.

[0099] Figure 8 This is a schematic diagram of a masking module provided in an embodiment of this application. Figure 8 As shown, the shielding module 113 may specifically include a first reset assembly 1131, a second reset assembly 1132, and a shielding slider 1133. The shielding slider 1133 is at least partially accommodated within the groove 1121, and is capable of operating within the groove 1121 along the thickness direction of the second housing 112 (i.e., Figure 3 The slider slides vertically to cover the groove 1121. The first reset component 1131 and the second reset component 1132 are housed in the receiving groove 1120, and the first reset component 1131 and the second reset component 1132 are located on both sides of the covering slider 1133.

[0100] Figure 9 This is a schematic diagram of the masking slider provided in an embodiment of this application. Figure 10 Another schematic diagram of the masking slider provided in an embodiment of this application. (See diagram below.) Figure 9 and Figure 10 As shown, in one embodiment, the shielding slider 1133 includes a slider body 11331 and a limiting protrusion 11332, wherein the limiting protrusion 11332 is used for sliding connection with the groove 1121. The slider body 11331 has a first contact surface S21 and a second contact surface S22.

[0101] The first contact surface S21 faces the first reset slider 11311, and the first contact surface S21 is not parallel to the sliding direction of the first reset slider 11311.

[0102] The second contact surface S22 faces the second reset slider 11321, and the sliding direction of the second contact surface S22 is not parallel to that of the second reset slider 11321. In this embodiment, the tilt direction of the surface is the tilt direction based on the thickness direction of the entire machine.

(See diagram.) Figure 12 and Figure 13 As shown, the inner wall of the groove 1121 is provided with a limiting groove 11211, which extends along the thickness direction of the second housing 112.

[0105] Figure 14 This is a schematic diagram of the shielding slider and groove provided in an embodiment of this application. Figure 14 As shown, in one embodiment, a portion of the slider body 11331 is accommodated in the receiving groove 1120, and another portion is accommodated in the recess 1121. The limiting protrusion 11332 is accommodated in the limiting slide groove 11211, and the sliding connection between the slider 1133 and the recess 1121 is achieved by sliding the limiting slide groove 11211. Figure 15 This is another schematic diagram of the shielding slider and groove provided in the embodiments of this application. Figure 16 for Figure 15 A cross-sectional view of the centrally masked slider and groove along the MM direction. (See figure) Figure 15 and Figure 16 As shown, when the electronic device 10 is in a flattened state, the shielding slider 1133 slides to the end of the groove 1121 away from the bottom wall S of the receiving groove 1120 to shield the groove 1121. Figure 17 This is another schematic diagram of the shielding slider and groove provided in the embodiments of this application. Figure 18 Another schematic diagram of the shielding slider and groove provided in an embodiment of this application. (See attached diagram.) Figure 17 and Figure 18As shown, when the electronic device 10 is in a folded state, the shielding slider 1133 slides to one end of the groove 1121 near the bottom wall S of the receiving groove 1120, so that the protrusion 1111 can be accommodated within the groove 1121. Figure 15 and Figure 17 As shown, the inner walls of both ends of the limiting groove 11211 along the thickness direction of the second housing 112 can limit the limiting protrusion 11332 in the limiting groove 11211, thereby preventing the blocking slider 1133 from dislodging from the groove 1121.

[0106] In application, when the electronic device 10 is in a flattened state, such as Figure 15 and Figure 16 As shown, the shielding slider 1133 is located at the end of the groove 1121 away from the bottom wall S of the receiving groove 1120. When the electronic device 10 is folded, the first housing 111 and the second housing 112 fold relative to each other. The protrusion 1111 rotates toward the groove 1121 as the first housing 111 does and abuts against the shielding slider 1133. Continuing to fold the electronic device 10, the protrusion 1111 can push the shielding slider 1133 to slide within the groove 1121 and reach the end of the groove 1121 near the bottom wall S of the receiving groove 1120, as shown. Figure 17 and Figure 18 As shown. At this time, the protrusion 1111 extends into and is accommodated in the groove 1121.

[0107] When the electronic device 10 is unfolded, the protrusion 1111 disengages from the groove 1121. Under the reset action of the first reset assembly 1131 and the second reset assembly 1132, the shielding slider 1133 slides within the groove 1121 in a direction away from the bottom wall S of the receiving groove 1120, and reaches the end of the groove 1121 opposite to the bottom wall S of the receiving groove 1120. At this time, the shielding slider 1133 can shield the groove 1121 from the user's perspective to prevent dust and other particles from falling into the groove 1121.

[0108] Figure 19 An exploded view of the first reset component provided in an embodiment of this application. Figure 8 and Figure 19 As shown, the first reset assembly 1131 includes a first reset slider 11311 and a first reset spring 11312. The first reset slider 11311 is disposed on one side of the shielding slider 1133 and abuts against the shielding slider 1133. The first reset slider 11311 is accommodated within a receiving groove 1120 and is capable of sliding along the receiving groove 1120 to achieve a sliding connection between the first reset slider 11311 and the second housing 112. The first reset spring 11312 is disposed on the side of the first reset slider 11311 away from the shielding slider 1133 and is connected to the inner wall of the receiving cavity 1120.

Figure 8 and Figure 20 As shown, similarly, the second reset assembly 1132 includes a second reset slider 11321 and a second reset spring 11322. The second reset slider 11321 is disposed on the side of the shielding slider 1133 opposite to the first reset slider 11311, and abuts against the shielding slider 1133. The second reset slider 11321 is accommodated within a receiving groove 1120 and is capable of sliding along the receiving groove 1120 to achieve a sliding connection between the second reset slider 11321 and the second housing 112.

[0110] Figure 21 A schematic diagram of the first reset slider provided in an embodiment of this application. Figure 22 Another schematic diagram of the first reset slider provided in an embodiment of this application. (See diagram below.) Figure 21 and Figure 22 As shown, the end of the first reset slider 11311 near the shielding slider 1133 can be L-shaped and has a first inclined surface S11 that abuts against the shielding slider 1133.

[0111] Figure 23 This is a schematic diagram of the second reset slider provided in an embodiment of this application. Figure 24 Another schematic diagram of the second reset slider provided in an embodiment of this application. (See diagram below.) Figure 23 and Figure 24 As shown, the end of the second reset slider 11321 near the shielding slider 1133 can be L-shaped and has a second inclined surface S12 that abuts against the shielding slider 1133.

[0112] Specifically, the extending direction of the receiving groove 1120 can be the same as the sliding direction of the first reset slider 11311 and the second reset slider 11321, so that the first reset slider 11311 achieves a sliding connection with the second housing 112 by sliding within the receiving groove 1120, and the second reset slider 11321 achieves a sliding connection with the second housing 112 by sliding within the receiving groove 1120. The sliding directions of the first reset slider 11311 and the second reset slider 11321 are opposite, and the sliding directions of the first reset slider 11311 and the second reset slider 11321 are respectively set at an angle to the sliding direction of the shielding slider 1133. In other words, neither the sliding direction of the first reset slider 11311 nor the sliding direction of the second reset slider 11321 is parallel to the sliding direction of the shielding slider 1133. In one specific embodiment, the sliding direction of the first reset slider 11311 and the sliding direction of the second reset slider 11321 may be perpendicular to the sliding direction of the shielding slider 1133.

[0113] Figure 25 Another schematic diagram of the masking slider, the first reset slider, and the second reset slider provided in the embodiments of this application is shown, wherein the dashed line view is a schematic diagram of the masking slider, the first reset slider, and the second reset slider along the direction of the arrow. Figure 25 As shown, in one embodiment, a first contact surface S21 is used to contact a first inclined surface S11, and the inclination direction of the first contact surface S21 is the same as the inclination direction of the first inclined surface S11. A second contact surface S22 is used to contact a second inclined surface S12, and the inclination direction of the second contact surface S22 is the same as the inclination direction of the second inclined surface S12.

[0114] Figure 26 This is another schematic diagram of the masking module provided in the embodiments of this application. Figure 27 for Figure 26 A magnified view of a portion of the occlusion module (Figure I). (See figure.) Figure 26 and Figure 27As shown, when the electronic device 10 is in a flattened state, the shielding slider 1133 is located at the end of the groove 1121 away from the bottom wall S of the receiving groove 1120. The side of the first contact surface S21 near the bottom wall S abuts against the side of the first inclined surface S11 away from the bottom wall S, and the side of the second contact surface S22 near the bottom wall S abuts against the side of the second inclined surface S12 away from the bottom wall S. When the electronic device 10 is folded, the shielding slider 1133 slides within the groove 1121 in a direction close to the bottom wall S. At this time, the first contact surface S21 moves toward the direction close to the bottom wall S, and the first contact surface S21 slides against the first inclined surface S11, thereby providing the shielding slider 1133 with a first thrust F1 perpendicular to the first inclined surface S11 to the first reset slider 11311. Since the first contact surface S21 is not parallel to the sliding direction of the first reset slider 11311, the first thrust F1 has a first component force f1 along the sliding direction of the first reset slider 11311, and the direction of this first component force f1 is as follows: Figure 27 The first component force f1 can push the first reset slider 11311 to slide away from the second reset slider 11321 (i.e., in the direction of compressing the first reset spring 11312). Simultaneously, the blocking slider 1133 pushes the second reset slider 11321 to move away from the first reset slider 11311 (e.g., from the middle horizontal direction to the left). Figure 27 (From the middle horizontal direction to the right).

[0115] Please continue reading. Figure 27 Similarly, the second contact surface S22 moves toward the direction closer to the bottom wall S, and the second contact surface S22 slides against the second inclined surface S12, thereby providing the shielding slider 1133 with a second thrust F2 perpendicular to the second inclined surface S12 to the second reset slider 11321. Since the sliding direction of the second contact surface S22 is not parallel to the sliding direction of the second reset slider 11321, the second thrust F2 has a second component force f2 along the sliding direction of the second reset slider 11321, the direction of which is as follows: Figure 27 The second component force f2 can push the second reset slider 11321 to slide away from the first reset slider 11311 (i.e., in the direction of compressing the second reset spring 11322).

Figure 30 for Figure 28 A magnified view of a portion of the central occlusion module (II). (See image below.) Figure 28 , Figure 29 and Figure 30As shown, when the electronic device 10 is in a folded state, the shielding slider 1133 reaches one end of the groove 1121 near the bottom wall S of the receiving groove 1120.

[0117] Figure 31 Another schematic diagram of the rotating shaft mechanism provided in an embodiment of this application. (See diagram below.) Figure 31 As shown, the first reset spring 11312 is located on the side of the first reset slider 11311 away from the shielding slider 1133, and is connected to the first reset slider 11311. Figure 32 for Figure 7 Partial enlarged view III of the second shell in the middle, Figure 33 Another schematic diagram of the first reset component provided in an embodiment of this application. (See diagram below.) Figure 32 and Figure 33 As shown, a first fixing post 11201 is provided on the inner wall of the receiving groove 1120 away from the first reset spring 11312. The end of the first reset spring 11312 away from the first reset slider 11311 is sleeved on the first fixing post 11201. When the first reset slider 11311 moves away from the second reset slider 11321, the first reset slider 11311 compresses the first reset spring 11312. When the electronic device 10 is unfolded, the first housing 111 and the second housing 112 unfold. The first reset spring 11312 provides a first reset force to the first reset slider 11311, and the first reset slider 11311 slides toward the second reset slider 11321 under the action of the first reset force, thereby pushing the shielding slider 1133 to slide in the groove 1121 to the end away from the bottom wall S.

[0118] Please continue reading. Figure 27 and Figure 30 During the sliding process of the first reset slider 11311 toward the second reset slider 11321, the first inclined surface S11 moves toward the direction closer to the second reset slider 11321, and the first contact surface S21 slides against the first inclined surface S11, thereby providing the first reset slider 11311 with a third thrust F3 perpendicular to the first inclined surface S11 (the third thrust F3 is opposite to the first thrust F1) to the shielding slider 1133. Since the sliding direction of the first contact surface S21 is not parallel to the sliding direction of the first reset slider 11311, the third thrust F3 has a third component force f3 along the sliding direction of the shielding slider 1133, the direction of which is as follows: Figure 27 The middle is vertically upward. This third component force f3 can push the shielding slider 1133 to slide in a direction away from the bottom wall S.

Figure 34As shown, the second reset spring 11322 is located on the side of the second reset slider 11321 away from the shielding slider 1133, and is connected to the second reset slider 11321. Figure 35 for Figure 7 Partial enlarged view IV of the second shell in the middle, Figure 36 Another schematic diagram of the second reset component provided in an embodiment of this application. (See diagram below.) Figure 35 and Figure 36 As shown, a second fixing post 11202 is provided on the inner wall of the receiving groove 1120 away from the second reset spring 11322. The end of the second reset spring 11322 away from the second reset slider 11321 is sleeved on the second fixing post 11202. When the second reset slider 11321 moves away from the first reset slider 11311, the second reset slider 11321 compresses the second reset spring 11322. When the electronic device 10 is unfolded, the first housing 111 and the second housing 112 unfold. The second reset spring 11322 provides a second reset force to the second reset slider 11321, and the second reset slider 11321 slides toward the first reset slider 11311 under the action of the second reset force, thereby pushing the shielding slider 1133 to slide in the groove 1121 to the end away from the bottom wall S.

[0120] Please continue reading. Figure 27 and Figure 30 During the sliding process of the second reset slider 11321 toward the first reset slider 11311, the second inclined surface S12 moves toward the first reset slider 11311, and the second contact surface S22 slides against the second inclined surface S12, thereby providing the second reset slider 11321 with a fourth thrust F4 perpendicular to the second inclined surface S12 (the fourth thrust F4 is opposite to the second thrust F12) to the shielding slider 1133. Since the sliding direction of the second contact surface S22 is not parallel to the sliding direction of the second reset slider 11321, the fourth thrust F4 has a fourth component force f4 along the sliding direction of the shielding slider 1133, the direction of which is as follows: Figure 27 Vertically upwards. This fourth component force f4 can push the shielding slider 1133 to slide in a direction away from the bottom wall S.

[0121] In the above embodiments, the first reset component 1131 and the second reset component 1132 can simultaneously reset the shielding slider 1133 to the end of the groove 1121 away from the flexible display screen 12, thereby shielding the groove 1121. It should be noted that in other embodiments of this application, the function of resetting the shielding slider 1133 can also be achieved by either the first reset component 1131 or the second reset component 1132. This application does not impose a specific limitation on the number of reset components.

Figure 37 As shown, a fastening edge 1112 is provided on the side of the first housing 111 away from the rotating module 110, and a protrusion 1111 is provided on the fastening edge 1112. When the first housing 111 and the second housing 112 are folded relative to each other, the fastening edge 1112 moves with the first housing 111 toward the second housing 112 and fits against the side of the second housing 112 away from the rotating module 110. And when the electronic device 10 is in the folded state, the fastening edge 1112 is located on the side of the first housing 111 toward the second housing 112.

[0123] Figure 38 This is a schematic diagram of a first reset component provided in an embodiment of this application. Figure 38 As shown, the first reset assembly 1131 also includes a first baffle 11313, which is located on the side of the first reset slider 11311 away from the bottom wall S and is rotatably connected to the second housing 112. That is, when the electronic device 10 is in a folded state, the first baffle 11313 is located on the side of the first reset slider 11311 facing the first housing 111.

Figure 41 As shown, when the electronic device 10 is in a flattened state, the first baffle 11313 can shield the first reset component 1131, making the first reset component 1131 hidden from the user's view. Furthermore, the flat surface of the first baffle 11313 can be coplanar with the surface of the second housing 112 facing the first housing 111, thereby improving the aesthetics of the rotating shaft mechanism 11.

Figure 42 As shown, when the electronic device 10 is folded, the fastening edge 1112 moves with the first housing 111 toward the second housing 112 and reaches a position abutting against the first baffle 11313. When the electronic device 10 continues to fold, the fastening edge 1112 pushes the first baffle 11313 to rotate relative to the second housing 112, thereby avoiding the fastening edge 1112 and achieving a seamless folding of the first housing 111 and the second housing 112.

[0126] like Figure 41 and Figure 42 As shown, in the above embodiment, the first reset assembly further includes a first rotating shaft 11314. The second housing 112 is provided with a first rotating hole. A first baffle 11313 is sleeved on the outer periphery of the first rotating shaft 11314, and both ends of the first rotating shaft 11314 are accommodated in the first rotating hole and can rotate within the first rotating hole, thereby realizing the rotational connection between the first baffle 11313 and the second housing 112 through the first rotating shaft 11314.

[0127] Figure 43 This is a schematic diagram of a second reset component provided in an embodiment of this application. Figure 43 As shown, the second reset assembly 1132 also includes a second baffle 11323, which is located on the side of the second reset slider 11321 away from the bottom wall S and is rotatably connected to the second housing 112. That is, when the electronic device 10 is in a folded state, the second baffle 11323 is located on the side of the second reset slider 11321 facing the first housing 111. Figure 44 A schematic diagram of the first baffle provided in an embodiment of this application. Figure 45 Another schematic diagram of the first baffle provided in an embodiment of this application.

Furthermore, the flat surface of the second baffle 11323 can be coplanar with the surface of the second housing 112 facing the first housing 111, thereby improving the aesthetics of the rotating shaft mechanism 11.

[0129] Figure 47 Another schematic diagram of the rotating shaft mechanism provided in an embodiment of this application. (See diagram below.) Figure 47 As shown, when the electronic device 10 is folded, the fastening edge 1112 moves with the first housing 111 toward the second housing 112 and reaches a position abutting against the second baffle 11323. When the electronic device 10 continues to fold, the fastening edge 1112 pushes the second baffle 11323 to rotate relative to the second housing 112, thereby avoiding the fastening edge 1112 and achieving a seamless folding of the first housing 111 and the second housing 112.

[0130] like Figure 46 and Figure 47As shown, in the above embodiment, the second reset assembly 1132 further includes a second rotating shaft 11324. The second housing 112 is provided with a second rotating hole. The second baffle 11323 is sleeved on the outer periphery of the second rotating shaft 11324, and both ends of the second rotating shaft 11324 are accommodated in the second rotating hole and can rotate within the second rotating hole, thereby realizing the rotational connection between the second baffle 11323 and the second housing 112 through the second rotating shaft 11324.

[0131] Figure 48 Another schematic diagram of the rotating shaft mechanism provided in an embodiment of this application. (See diagram below.) Figure 48 As shown, the first reset slider 11311 has a first fixing part 113111 at one end near the first reset spring 11312. The first fixing part 113111 is connected to the first reset spring 11312 on the side facing the first reset spring 11312. The first baffle 11313 has a first contact slope S31 on the side facing the first reset spring 11312. The inclination direction of the first contact slope S31 is not parallel to the sliding direction of the first reset slider 11311, and the inclination direction of the first contact slope S31 is not parallel to the rotation direction of the first baffle 11313. When the electronic device 10 is folded, under the action of the shielding slider 1133, the first reset slider 11311 moves in the direction of compressing the first reset spring 11312, so that the first reset spring 11312 is in a compressed state. At the same time, the first baffle 11313 rotates toward the receiving groove 1120 under the action of the fastening edge 1112. When the electronic device 10 is in a folded state, the end of the first reset slider 11311 away from the shielding slider 1133 is spaced a certain distance from the first baffle 11313.

[0132] Figure 49 This is another schematic diagram of the rotating shaft mechanism provided in the embodiments of this application. Figure 50 for Figure 49 A partial enlarged view VI of the first reset component. (See diagram VI.) Figure 49 and Figure 50 As shown, when the electronic device 10 unfolds, the first housing 111 and the second housing 112 unfold relative to each other. The engaging edge 1112 gradually moves away from the first baffle 11313. During the reset process of the shielding slider 1133, as the first reset slider 11311 moves in the direction toward the shielding slider 1133 (e.g., ... Figure 50Sliding in the direction of horizontal to the right, at the position where the first fixed part 113111 contacts the first contact slope S31, the first reset slider 11311 applies a fifth thrust F5 to the first baffle 11313. Since the inclination direction of the first contact slope S31 is not parallel to the sliding direction of the first reset slider 11311, and the inclination direction of the first contact slope S31 is not parallel to the rotation direction of the first baffle 11313, the fifth thrust F5 has a fifth component force f5 along the rotation direction of the first baffle 11313. This fifth component force f5 can push the first baffle 11313 in a direction away from the receiving groove 1120 (e.g., from the horizontal direction to the right). Figure 50 Rotate in the direction indicated by the curved arrow.

[0133] Figure 51 Another schematic diagram of the rotating shaft mechanism provided in an embodiment of this application. (See diagram below.) Figure 51 As shown, the second reset slider 11321 has a second fixing part 113211 at one end near the second reset spring 11322. The second fixing part 113211 is connected to the first and second reset springs 11322 on the side facing the second reset spring 11322. The second baffle 11323 has a second contact slope S32 on the side facing the second reset spring 11322. The inclination direction of the second contact slope S32 is not parallel to the sliding direction of the second reset slider 11321, and the inclination direction of the second contact slope S32 is not parallel to the rotation direction of the second baffle 11323. When the electronic device 10 is folded, under the action of the shielding slider 1133, the second reset slider 11321 moves in the direction of compressing the second reset spring 11322, so that the second reset spring 11322 is in a compressed state. At the same time, the second baffle 11323 rotates toward the receiving groove 1120 under the action of the fastening edge 1112. When the electronic device 10 is in a folded state, the end of the second reset slider 11321 away from the shielding slider 1133 is spaced a certain distance from the second baffle 11323.

Figure 53 for Figure 52 Partial enlarged view VII of the second reset component. (See diagram below.) Figure 52 and Figure 53 As shown, when the electronic device 10 is unfolded, the first housing 111 and the second housing 112 unfold relative to each other. The fastening edge 1112 gradually moves away from the second baffle 11323. During the reset process of the shielding slider 1133, as the second reset slider 11321 moves in the direction toward the shielding slider 1133 (e.g., ... Figure 53Sliding in the direction of leftward movement (from the middle horizontal direction), at the position where the second fixed part 113211 contacts the second contact slope S32, the second reset slider 11321 applies a sixth thrust F6 to the second baffle 11323. Since the inclination direction of the second contact slope S32 is not parallel to the sliding direction of the second reset slider 11321, and the inclination direction of the second contact slope S32 is not parallel to the rotation direction of the second baffle 11323, the sixth thrust F6 has a sixth component force f6 along the rotation direction of the second baffle 11323. This sixth component force f6 can push the second baffle 11323 in a direction away from the receiving groove 1120 (e.g., from the middle horizontal direction to the left). Figure 53 Rotate in the direction indicated by the curved arrow.

Figure 54 and Figure 55 As shown, the second housing 112 has a first limiting portion 1122 extending toward the first baffle 11313 on the side near the first baffle 11313. The first limiting portion 1122 is used to limit the rotation angle of the first baffle 11313 to prevent the first baffle 11313 from rotating excessively and damaging the electronic device 10. Figure 56 for Figure 4 Local magnification Figure X , Figure 57 for Figure 46 A magnified view of a portion of the second shell, shown in section XI. Figure 56 and Figure 57 As shown, similarly, the second housing 112 has a second limiting portion 1123 extending toward the second baffle 11323 on the side near the second baffle 11323. The second limiting portion 1123 is used to limit the rotation angle of the second baffle 11323 to prevent the second baffle 11323 from rotating excessively and damaging the electronic device 10.
