Description

Technical Field

[0001] This application relates to the field of terminal equipment technology, and more particularly to an electronic device. Background Technology

[0002] With the development of terminal technology, the screen sizes of mobile phones and other electronic devices are getting larger and larger. In order to meet users' portability needs while increasing the screen size, foldable screen devices have evolved from the original two-fold structure to a three-fold structure.

[0003] A three-fold electronic device consists of two outer casings and one inner casing. The two outer casings are rotatably positioned on opposite sides of the inner casing. Compared to two-fold and single-screen electronic devices, the three-fold design offers more operable casings due to its three components. However, improper operation can easily lead to problems such as broken hinges or loose connections between casings, hindering bending and reducing the device's reliability.

[0004] Therefore, there is a need for an electronic device with high reliability. Summary of the Invention

[0005] To address the aforementioned problems, this application provides an electronic device that is flexible and can effectively improve reliability.

[0006] The electronic device provided in this application includes a first frame, a second frame, a third frame, a first rotating shaft mechanism, a second rotating shaft mechanism, and a first limiting mechanism. The first frame and the second frame are rotatably disposed on opposite sides of the first rotating shaft mechanism. The second frame and the third frame are rotatably disposed on opposite sides of the second rotating shaft mechanism. The first limiting mechanism includes a first limiting part and a second limiting part, the first limiting part being disposed on the first frame and the second limiting part being disposed on the second frame and the second rotating shaft mechanism. When the first frame and the second frame are in a non-closed state, the second limiting part is configured to cooperate with the first limiting part to prevent the second rotating shaft mechanism from driving the third frame to rotate relative to the second frame. When the first frame and the second frame are in a closed state, the first limiting part is configured to cooperate with the second limiting part to allow the second rotating shaft mechanism to drive the third frame to rotate toward the second frame.

[0007] The electronic device provided in this application, when the first frame is not fastened to the second frame, has its second limiting part not driven by the first limiting part, thus restricting the rotation of the second pivot mechanism and preventing the third frame from rotating towards the second frame. Only when the first frame is fastened to the second frame can the first limiting part cooperate with the second limiting part to release the rotation restriction on the second pivot mechanism, allowing the third frame to rotate towards the second frame. Therefore, by determining whether the third frame can be driven to rotate based on the closed state of the first frame, the rotation sequence of the electronic device frame can be restricted to a first frame followed by the third frame, achieving cross-axis linkage. This avoids damage to the pivot and screen due to incorrect rotation sequence, effectively ensuring the service life of the pivot and screen, and consequently, the service life of the electronic device.

[0008] In some feasible implementations, the first limiting part is located on the first surface of the first frame and extends along a first direction; the first surface faces the second frame in the closed state, and the first direction is the thickness direction of the electronic device. This shortens the engagement path between the first and second limiting parts and improves the operability of the first limiting part.

[0009] In some feasible implementations, the second frame includes a first limiting hole, which is formed by a recess inward from the second surface of the second frame along a first direction. In the closed state, the first limiting hole faces the first limiting part; the second surface faces the first frame in the closed state. The second rotating shaft mechanism includes a second limiting hole, which communicates with the first limiting hole and extends along a second direction. The second direction is perpendicular to the first direction and is the length direction of the electronic device. In this way, the second limiting part can be slidably disposed within the second frame and the second rotating shaft mechanism through the first and second limiting holes, and can cooperate with the first limiting part by sliding, simplifying the cooperation method. Furthermore, opening through holes inside the second frame and the second rotating shaft mechanism does not add additional connecting parts, does not affect the overall size of the electronic device, and is beneficial for miniaturization.

[0010] In some feasible implementations, the second limiting part includes a limiting component and a sliding component; the limiting component is slidably disposed within the second limiting hole, and the sliding component is slidably disposed within the first limiting hole; in the non-closed state, the main body of the limiting component is located within the second limiting hole, and the remaining part slides into the first limiting hole and abuts against the sliding component to prevent the second rotating shaft mechanism from driving the third frame to rotate relative to the second frame; in the closed state, the first limiting part is embedded in the first limiting hole, pushing the sliding component to slide within the first limiting hole to drive the limiting component to slide along the second direction, and the remaining part of the limiting component slides into the second limiting hole, so that the second rotating shaft mechanism can drive the third frame to rotate toward the second frame. Thus, by the sliding engagement of the sliding component and the limiting component within the first and second limiting holes, the operation of limiting and releasing the second rotating shaft mechanism is achieved.

[0011] In some feasible implementations, the first limiting hole includes a first sub-limiting hole and a second sub-limiting hole that are connected. The first sub-limiting hole is formed by a recess inward along a first direction from the second surface of the second frame. The second sub-limiting hole is located at the end of the first sub-limiting hole facing the second limiting hole along a second direction, and the second sub-limiting hole is connected to the second limiting hole. The sliding assembly includes a first sliding member and a second sliding member that are slidably engaged. In the non-closed state, the first sliding member and the second sliding member are abutted against each other along the first direction and located within the first sub-limiting hole. The remaining part of the limiting assembly slides into the second sub-limiting hole and abuts against the second sliding member. In the closed state, the first limiting part is embedded in the first sub-limiting hole, pushing the first sliding member to slide along the first direction, thereby pushing the second sliding member to slide along the second direction into the second sub-limiting hole, so as to drive the limiting assembly to slide along the second direction, and the remaining part of the limiting assembly slides into the second limiting hole. In this way, the structure of the second limiting part is effectively simplified, thereby effectively simplifying the installation space of the second limiting part and facilitating the miniaturization of electronic devices.

[0012] In some feasible implementations, along the second direction, the sum of the widths of the first and second sub-restricting holes is less than the sum of the widths of the first and second sliding members. This helps to ensure the sliding stability of the first and second sliding members during the transition from the closed to the unfolded state of the first and second frames, effectively guaranteeing the reset of the second sliding member.

[0013] In some feasible implementations, the end of the first slider facing the second slider includes a first inclined surface, which is inclined in a first direction toward the limiting component; the end of the second slider facing the first slider includes a second inclined surface, which is inclined in the first direction toward the limiting component; the first and second inclined surfaces are parallel, and their sliding engagement enables relative sliding between the first and second sliders. Thus, through the engagement of the first and second inclined surfaces, the thrust in the first direction acting on the first slider can be converted into a force pushing the second slider in the second direction, better achieving the sliding engagement between the first and second sliders.

[0014] In some feasible implementations, the limiting component includes a first limiting member and a first elastic member. In the non-closed state, the remaining portion of the first limiting member slides into the second sub-limiting hole and abuts against the second sliding member. The main body of the first limiting member is disposed within the second limiting hole via the first elastic member, which is in its initial state. In the closed state, the first limiting member slides along a second direction, compressing the first elastic member, which is then in a compressed state. Thus, after the thrust acting on the first limiting member disappears, the first elastic member can recover its elastic deformation, achieving the reset of the first limiting member.

[0015] In some feasible implementations, the first limiting member includes an annular protrusion surrounding its outer surface. A first elastic member is sleeved on the outside of the first limiting member, with one end connected to the annular protrusion and the other end abutting against the bottom surface of the second limiting hole. The inner surface of the second limiting hole includes an annular groove, into which the annular protrusion is embedded. Along the second direction, the length of the annular groove is greater than the length of the annular protrusion. The annular protrusion is configured to follow the sliding of the first limiting member along the second direction, sliding within the annular groove along the second direction. Thus, the reciprocating movement of the annular protrusion within the annular groove restricts its movement along the second direction, preventing the first limiting member from dislodging during movement along the second direction, thereby ensuring the stability of the restriction on the second rotating shaft mechanism and the restriction release operation.

[0016] In some feasible implementations, the annular protrusion includes a first end face and a second end face that are opposite to each other along a second direction, and the annular groove includes a third end face and a fourth end face that are opposite to each other along the second direction. In the non-closed state, the first end face of the annular protrusion abuts against the third end face of the annular groove, and the second and fourth end faces have a first distance. In the closed state, the second end face of the annular protrusion abuts against the fourth end face of the annular groove, and the first and third end faces have a first distance. This ensures the stability of the annular protrusion during reciprocating movement, thereby ensuring the stability of the restriction on the second rotating shaft mechanism and the restriction release operation.

[0017] In some feasible implementations, the electronic device further includes: a first locking mechanism; the first locking mechanism includes: a first locking part and a second locking part; the first locking part is disposed on the first frame; the second locking part is disposed on the second pivot mechanism; the first locking part is configured to slide in cooperation with the second locking part, locking the first frame to the second frame in a closed state, and separating the first frame from the second frame in an open state. This allows the first frame to be locked or unlocked as needed, improving the operability of the electronic device.

[0018] In some feasible implementations, the first frame includes a first sliding groove and a second sliding groove that are connected. The first sliding groove communicates with the external environment, and the second sliding groove is located at the end of the first sliding groove facing away from the external environment along a second direction. The first locking part includes a first locking member and a second locking member. The first locking member is slidably disposed within the first sliding groove, and one end protrudes from the first sliding groove to the external environment. The first locking member is configured to slide within the first sliding groove along the first direction when subjected to a force along the first direction. The second locking member is slidably disposed within the second sliding groove, and one end of the second locking member protrudes from the first surface of the first frame and extends toward the direction of the second locking part. In this way, by moving the end of the first locking member located in the external environment, the locking and unlocking of the first frame and the second frame can be achieved, making the operation simple.

[0019] In some feasible implementations, the second locking part includes a third slide groove and a fourth slide groove that are connected. The third slide groove is formed by a recess inward along a first direction from the surface of the second rotating shaft mechanism, and the fourth slide groove extends into the second rotating shaft mechanism relative to the third slide groove along a second direction. In the closed state, the protruding end of the second locking member is embedded in the third slide groove. The second locking member is configured to slide along the second direction under the force of the first locking member when it slides along the first direction, and the protruding end of the second locking member moves into the fourth slide groove to lock the first frame and the second frame. In this way, setting the second locking part in the form of a slide groove effectively simplifies the sliding fit between the first locking part and the second locking part, and eliminates the need for additional connecting parts, which is beneficial for miniaturizing electronic devices.

[0020] In some feasible implementations, the second locking member includes a first locking rod, a first follower wheel, and a first latch. The first locking rod is slidably disposed within a second slide groove. The first follower wheel is disposed on the first locking rod and abuts against a first end of the first locking member. The first latch is disposed at one end of the first locking rod protruding from a first surface and extends along a second direction. In the closed state, the first latch is embedded in a third slide groove, and the first follower wheel is configured to be subjected to a force from the first locking member along the first direction, pushing the first locking rod to move along the second direction, thereby causing the first latch to embed into a fourth slide groove. In this way, through the cooperation of the first latch and the fourth slide groove, no additional locking components are required, effectively simplifying the locking operation of the first frame and the second frame.

[0021] In some feasible implementations, the first frame further includes a fifth slide groove, which communicates with the second slide groove, and the length direction of the fifth slide groove is parallel to the second direction. The second locking member also includes a second elastic member, which is located within the fifth slide groove. One end of the second elastic member is connected to the first locking rod, and the other end is connected to the first frame. In the non-closed state, the first locking rod is close to the first locking member, and the second elastic member is in its initial state. In the closed state, the first locking rod slides along the second direction and moves away from the first locking member, compressing the second elastic member, which is then in a compressed state. Thus, by providing the second elastic member, during the unlocking process of the first frame, the elasticity of the second elastic member assists in the reset of the first locking member, preventing jamming during the operation of the first locking member.

[0022] In some feasible implementations, the end of the first locking member that abuts against the second locking member includes a third inclined surface, which is inclined in a first direction toward the second locking member; the second locking member includes a fourth inclined surface, which is inclined in the first direction toward the second locking member; the third inclined surface is configured to slide in engagement with the fourth inclined surface, or to slide in engagement with the first follower wheel, thereby enabling the second locking member to slide relative to the first locking member. This increases the versatility of the sliding engagement between the first and second locking members.

[0023] In some feasible implementations, the first locking mechanism and the first limiting mechanism are arranged at opposite ends of the electronic device along the second direction. This allows for the utilization of the installation space in the second direction of the electronic device, enabling the first and second locking mechanisms to be rationally positioned so that the electronic device experiences balanced forces on both sides along the second direction.

[0024] In some feasible implementations, the first locking mechanism and the first limiting mechanism are located at the same end of the electronic device; the second locking member is located within the first limiting part, and the first latch of the second locking member protrudes from the first limiting part toward the surface of the second frame in the closed state. In this way, the first locking mechanism and the first limiting part can be integrated together, further reducing the installation space of the first locking mechanism and facilitating the miniaturization of the electronic device.

[0025] This application also provides an electronic device, including a first frame, a second frame, a third frame, a first pivot mechanism, a second pivot mechanism, a limiting and locking integrated member, a third limiting part, and a second locking mechanism; the first frame and the second frame are rotatably disposed on opposite sides of the first pivot mechanism; the second frame and the third frame are rotatably disposed on opposite sides of the second pivot mechanism; the second locking mechanism includes a third locking part and a fourth locking part, the third locking part being disposed on the first frame and the fourth locking part being disposed on the second pivot mechanism; the limiting and locking integrated member is disposed on the first frame, and the third limiting part is disposed on the second frame and the third pivot mechanism. The second rotating shaft mechanism, when the first and second frames are in the open state, is configured to: cooperate with the third limiting part to prevent the second rotating shaft mechanism from driving the third frame to rotate relative to the second frame; and cooperate with the third and fourth locking parts to separate the first frame from the second frame; when the first and second frames are in the closed state, the limiting locking component is configured to: cooperate with the third limiting part to allow the second rotating shaft mechanism to drive the third frame to rotate toward the second frame; and cooperate with the third and fourth locking parts to lock the first frame into the second frame. Thus, by providing the limiting locking component, not only can the rotation sequence of the frames be restricted, but a locking function can also be achieved, simplifying the structure and improving the ease of use of the electronic device, effectively enhancing its operability and reliability.

[0026] In some feasible implementations, the first frame includes a sixth slide groove and a seventh slide groove that are connected. The sixth slide groove communicates with the external environment, and the seventh slide groove is located at the end of the sixth slide groove facing away from the external environment along a second direction. A locking member is slidably disposed within the sixth slide groove, with one end protruding from the sixth slide groove to the external environment. The locking member is configured to slide within the sixth slide groove along a first direction when subjected to a force along a first direction, where the first direction is the thickness direction of the electronic device, and the second direction is perpendicular to the first direction and is the length direction of the electronic device. A third locking part is slidably disposed within the seventh slide groove, with one end of the third locking part protruding from the first surface of the first frame and extending toward the direction of the fourth locking part. The first surface faces the second frame in the closed state. In this way, the locking of the first frame and the second frame is achieved.

[0027] In some feasible implementations, the fourth locking part includes a communicating eighth slide groove and a ninth slide groove. The eighth slide groove is formed by a recess inwardly recessed surface of the second rotating shaft mechanism along a first direction, and the ninth slide groove extends into the second rotating shaft mechanism relative to the eighth slide groove along a second direction; the second direction is the length direction of the electronic device. In the closed state, the protruding end of the third locking part is embedded in the eighth slide groove. The third locking part is configured to slide along the second direction when the restricted locking unit slides along the first direction, and the protruding end of the third locking part moves into the ninth slide groove to lock the first frame and the second frame. In this way, the cooperation between the third locking part and the fourth locking part is simple and helps to simplify the structure.

[0028] In some feasible implementations, the integrated limiting and locking component includes a first part, a second part, and a third part. The first part protrudes into the external environment, while the second and third parts are respectively disposed at the ends of the first part facing away from the external environment, and are arranged along a third direction. This third direction is perpendicular to the first and second directions, respectively, and is the width direction of the electronic device. The first part is configured to synchronously drive the second and third parts to move along the first direction when subjected to a force along the first direction. In this way, the first part can synchronously drive the second and third parts to cooperate with the third limiting part and the third locking part, respectively, so that a single functional component can simultaneously complete the limiting and locking functions, which helps to simplify the structure of the integrated limiting and locking component.

[0029] In some feasible implementations, the first direction includes a first sub-direction and a second sub-direction. The first sub-direction is the direction from the first frame to the second frame in the closed state, and the second sub-direction is the direction from the second frame to the first frame in the closed state. In the closed state, the first part is configured to simultaneously drive the second part and the third part to move along the first sub-direction when subjected to a force along the first sub-direction, causing the second part to abut against the third limiting part. The second part is configured to cooperate with the third limiting part so that the second rotating shaft mechanism can drive the third frame to rotate toward the second frame. The third part abuts against the third locking part and is configured to cooperate with the third locking part and the fourth locking part to lock the first frame into the second frame. In the closed state, the first part is configured to simultaneously drive the second part and the third part to move along the second sub-direction when subjected to a force along the second sub-direction. The second part is configured to cooperate with the third limiting part to prevent the second rotating shaft mechanism from driving the third frame to rotate relative to the second frame. The third part is configured to cooperate with the third locking part and the fourth locking part to separate the first frame from the second frame. In this way, by moving the limiting locking member to one end in the external environment, the limiting locking member can simultaneously achieve the limiting of the second rotating shaft mechanism and the locking and unlocking of the first frame, making the operation simple.

[0030] In some feasible implementations, the sixth slide rail includes a first sub-slide rail, a second sub-slide rail, and a third sub-slide rail that are connected to each other. The first sub-slide rail extends along a second direction and communicates with the external environment. The second and third sub-slide rails both extend along a first direction and are located at the ends of the first sub-slide rail that are away from the external environment, and are arranged along a third direction. A first part is slidably disposed in the first sub-slide rail, a second part is slidably disposed in the second sub-slide rail, and a third part is slidably disposed in the third sub-slide rail. A seventh slide rail is located along the second direction at the end of the third sub-slide rail that is away from the first sub-slide rail, and is connected to the third sub-slide rail. The second sub-slide rail penetrates through the first surface. In this way, on the one hand, it does not occupy the installation space of the first surface, and on the other hand, the process of the second part cooperating with the third limiting part by extending out of the second sub-slide rail is simple.

[0031] In some feasible implementations, the electronic device further includes: a boss; the boss is located on the first surface of the first frame and extends along a first direction; a third part is disposed within the boss, and a second part is disposed outside the boss; a third sub-slide extends from the first frame to the boss. In this way, on the one hand, when the electronic device has a thinning requirement and cannot meet the installation requirements of the third locking part, the boss provides installation space for the third locking part and the third part. On the other hand, when the first frame contains other components that would affect the sliding cooperation of the locking assembly with the third locking part and the second locking mechanism along one direction, the boss shortens the cooperation path between the locking assembly and the third locking part and the second locking mechanism, effectively simplifying operation.

[0032] In some feasible implementations, the second and third parts are integrally formed; or the second and third parts are spaced apart along a third direction. This allows for more flexible arrangement of the second and third parts, enabling their specific forms to be adaptively adjusted according to the installation conditions of the locking assembly.

[0073] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are all within the protection scope of this application.

[0074] In the following description, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0075] Furthermore, in this application, directional terms such as "upper," "lower," "inner," and "outer" are defined relative to the indicated placement of the components in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the placement of the components in the accompanying drawings.

[0076] Figure 1 This is a schematic diagram of an electronic device in its unfolded state.

[0077] See Figure 1 As shown, the electronic device includes a first body 10, a second body 20, a third body 30, a folding screen 40, a small folding hinge 50, and a large folding hinge 60.

[0078] The first body 10 and the second body 20 are rotatably disposed on both sides of the small folding shaft 50. The first body 10 can rotate via the small folding shaft 50 in a direction closer to or away from the second body 20 to achieve folding and unfolding of the first body 10. For example, the first body 10 can rotate along the A1 direction closer to the second body 20, and the angle between the first body 10 and the second body 20 gradually decreases, achieving the folding operation of the first body 10. The first body 10 can also rotate in the opposite direction of the A1 direction away from the second body 20, and the angle between the first body 10 and the second body 20 gradually increases, achieving the unfolding operation of the first body 10.

[0079] The second fuselage 20 and the third fuselage 30 are rotatably mounted on either side of the large folding shaft 60. The third fuselage 30 can rotate via the large folding shaft 60 in a direction closer to or further away from the second fuselage 20 to fold or unfold. For example, the third fuselage 30 can rotate along direction A2 towards the second fuselage 20, with the angle between the third fuselage 30 and the second fuselage 20 gradually decreasing, thus folding the third fuselage 30. The third fuselage 30 can also rotate in the opposite direction of direction A2 away from the second fuselage 20, with the angle between the third fuselage 30 and the second fuselage 20 gradually decreasing, thus unfolding the third fuselage 30. Directions A1 and A2 are opposite directions. For example, direction A1 can be clockwise, and direction A2 can be counterclockwise.

[0080] To facilitate the explanation of the positions of various components in the electronic device, this application embodiment exemplarily establishes a three-dimensional coordinate system based on the electronic device, wherein the x-axis direction is the width direction of the electronic device, the y-axis direction is the length direction of the electronic device, and the z-axis direction is the thickness direction of the electronic device.

[0081] Figure 2 This is a schematic diagram of the folding process of an electronic device.

[0082] Figure 2 Image (a) shows the electronic device with all three bodies in an unfolded state. Figure 2 Image (b) shows the first body 10 of the electronic device rotating to a closed state with the second body 20. Figure 2As shown in (c), the first body 10 and the third body 30 in the electronic device are both rotated to a closed state with the second body 20.

[0083] Combination Figure 1 and Figure 2 As shown in (a), when the electronic device is in the unfolded state and the electronic device is operated in the order of folding the first body 10 first, after the first body 10 is folded and the third body 30 is not folded, the following can be obtained: Figure 2 The state shown in (b) is as follows. In this state, the third fuselage 30 can be folded further, so that the first fuselage 100 and the third fuselage 30 are stacked sequentially on the second fuselage 20, resulting in... Figure 2 The state shown in (c) completes the folding operation of the entire electronic device. Figure 2 The fuselage folding sequence shown is that the first fuselage 10 is folded first, followed by the third fuselage 30.

[0084] It is worth noting that when the three-fold electronic device is folded, the third body 30 is located outside the first body 10. Therefore, in order to ensure the overall aesthetics of the three-fold electronic device, the width of the third body 30 is usually greater than the width of the first body 10.

[0085] Figure 3 This is a schematic diagram of an electronic device with an incorrect folding order.

[0086] Combination Figure 1 and Figure 3 As shown, when the three-fold electronic device is operated in the order of first folding the third body 30 and then folding the first body 10, the following can be obtained: Figure 3 The state shown is such that the electronic device is not operated in the correct folding sequence, and the large folding hinge 60 will be damaged during the initial folding process. Furthermore, since the width of the third body 30 is greater than the width of the first body 10, when the third body 30 is folded before the first body 10, the folding screen 40 on the first body 10 will collide with the end of the third body 30, causing damage to the folding screen 40 on the first body 10 and reducing the lifespan of the electronic device; furthermore, it will prevent the first body 10 from folding towards the second body 20.

[0087] In order to solve the technical problem of screen and hinge damage caused by the improper folding sequence of electronic devices, this application provides an electronic device that can limit the folding sequence of the device body, which helps to ensure the service life of the hinge and folding screen, and thus ensures the service life of the electronic device.

[0088] Figure 4 This is a schematic diagram of the structure of an electronic device provided in an embodiment of this application; Figure 5This is a schematic diagram of a structure provided in an embodiment of this application, in which the first frame and the second frame are in an unclosed state.

[0089] Combination Figure 4 and Figure 5 As shown, the electronic device provided in this application embodiment includes a first frame 110, a second frame 120, a third frame 130, a first pivot mechanism 210, a second pivot mechanism 220, a first limiting mechanism, and a screen 100.

[0090] The first frame 110 and the second frame 120 are rotatably disposed on both sides of the first rotating shaft mechanism 210. The first frame 110 can rotate in a direction closer to or farther from the second frame 120 via the first rotating shaft mechanism 210, and the second frame 120 can also rotate in a direction closer to or farther from the first frame 110 via the first rotating shaft mechanism 210.

[0091] The second frame 120 and the third frame 130 are rotatably disposed on both sides of the second rotating shaft mechanism 220. The second frame 120 can rotate in a direction closer to or farther from the third frame 130 via the second rotating shaft mechanism 220, and the third frame 130 can also rotate in a direction closer to or farther from the second frame 120 via the second rotating shaft mechanism 220.

[0092] The screen 100 covers the first frame 110, the second frame 120, the third frame 130, the first pivot mechanism 210, and the second pivot mechanism 220, and is connected to the first frame 110, the second frame 120, and the third frame 130 respectively. During the rotation of the first frame 110 and the third frame 130 relative to the second frame 120, the screen 100 can bend or unfold. The screen 100 can be a flexible screen, and a bending area is provided at the position opposite to the first pivot mechanism 210 and the second pivot mechanism 220, so that the screen 100 can be bent during the rotation of the first frame 110 driven by the first pivot mechanism 210 and the third frame 130 driven by the second pivot mechanism 220.

[0093] The first limiting mechanism is used to limit the rotation of the third frame 130. The first limiting mechanism includes a first limiting part 310 and a second limiting part 320. The first limiting part 310 is disposed in the first frame 110, and the second limiting part 320 is disposed in the second frame 120 and the second rotating shaft mechanism 220.

[0094] When the first frame 110 and the second frame 120 are in an open state, the second limiting part 320 is configured to cooperate with the first limiting part 310 to prevent the second rotating shaft mechanism 220 from driving the third frame 130 to rotate relative to the second frame 120. The open state refers to the state where the first frame 110 and the second frame 120 are not closed. For example, the open state may include: the first frame 110 and the second frame 120 being in a flattened state, or a state where the rotation angle between the first frame 110 and the second frame 120 is small.

[0095] When the first frame 110 and the second frame 120 are in the closed state, the first limiting part 310 is configured to cooperate with the second limiting part 320, so that the second rotating shaft mechanism 220 can drive the third frame 130 to rotate toward the second frame 120. Here, the closed state refers to the state when the first frame 110 rotates to engage with the second frame 120.

[0096] Thus, when the first frame 110 is not engaged with the second frame 120, the second limiting part 320 is not driven by the first limiting part 310, thus restricting the rotation of the second pivot mechanism 220, preventing the third frame 130 from rotating towards the second frame 120. Only when the first frame 110 is engaged with the second frame 120 can the first limiting part 310 cooperate with the second limiting part 320 to release the rotation restriction on the second pivot mechanism 220, allowing the third frame 130 to rotate towards the second frame 120. Therefore, by determining whether the third frame 130 can be driven to rotate based on the closed state of the first frame 110, the rotation sequence of the electronic device frame can be restricted to the order of first frame 110 followed by third frame 130, achieving cross-axis linkage. This avoids damage to the pivot and screen due to incorrect rotation sequence, effectively ensuring the service life of the pivot and screen, and consequently, the service life of the electronic device.

[0097] Continue to combine Figure 4 and Figure 5 The first limiting part 310 is located on the first surface 111 of the first frame 110 and extends along the first direction. The first surface 111 is the surface of the first frame 110 facing the second frame 120 when the first frame 110 is closed, and the first direction is the thickness direction of the electronic device.

[0098] By setting the first limiting part 310 on the first surface 111 of the first frame 110, the distance between the first limiting part 310 and the second frame 120 gradually decreases during the rotation of the first frame 110 toward the second frame 120. When the first frame 110 and the second frame 120 are in a closed state, the first limiting part 310 can cooperate with the second limiting part 320 through the rotation of the first frame 110, which shortens the cooperation path of the first limiting part 310 and the second limiting part 320 and improves the operability of the first limiting part 310.

[0099] Figure 6 This is a schematic diagram of a structure provided in this application embodiment where the first frame and the second frame are in a closed state; Figure 7 This is a cross-sectional view provided in an embodiment of this application when the first frame and the second frame are in a non-closed state.

[0100] Combination Figure 6 and Figure 7 As shown, the second frame 120 includes a first limiting hole 121, which is formed by a recess inward from the second surface 122 of the second frame 120 along a first direction. That is, the first limiting hole 121 is formed by a recess inward along the thickness direction of the electronic device. The second surface 122 faces the first frame 110 in the closed state. When the first frame 110 and the second frame 120 are in the closed state, the first surface 111 and the second surface 122 are opposite and parallel; when the first frame 110 and the second frame 120 are in the unfolded state, the plane containing the first surface 111 is coplanar with the plane containing the second surface 122.

[0101] When the first frame 110 and the second frame 120 are in the closed state, the first limiting hole 121 is disposed opposite to the first limiting part 310, and the first limiting part 310 can rotate into the first limiting hole 121 as the first frame 110 rotates.

[0102] The second rotating shaft mechanism 220 includes a second limiting hole 221, which communicates with the first limiting hole 121 and extends along a second direction. The second direction is perpendicular to the first direction and is the length direction of the electronic device.

[0103] In this way, the second limiting part 320 can be slidably disposed within the second frame 120 and the second rotating shaft mechanism 220 through the first limiting hole 121 and the second limiting hole 221, and can cooperate with the first limiting part 310 by sliding, which simplifies the cooperation method. Moreover, the form of opening through holes inside the second frame 120 and the second rotating shaft mechanism 220 does not add additional connecting parts, does not affect the overall size of the electronic device, and is conducive to the miniaturization of the electronic device.

[0104] Continue to combine Figure 6and Figure 7 As shown, the second limiting part 320 may include a limiting component 321 and a sliding component 322.

[0105] The limiting component 321 is slidably disposed within the second limiting hole 221 and can slide within the second limiting hole 221 in the second direction.

[0106] The sliding component 322 is slidably disposed within the first limiting hole 121 and can slide within the first limiting hole 121 along the first direction and the second direction.

[0107] The limiting component 321 includes a first limiting member 3211, the length direction of which is parallel to the y-axis. The first limiting member 3211 includes a main body portion a1 and a remaining portion a2 connected to each other. The main body portion a1 can be the portion away from the sliding component 322 and is slidably disposed within the second limiting hole 221. The remaining portion a2 can be the portion close to the sliding component 322 and is slidably disposed within the first limiting hole 121 and the second limiting hole 221.

[0108] When the first frame 110 and the second frame 120 are in a non-closed state, the main body a1 of the limiting component 321 is located inside the second limiting hole 221, and the remaining part a2 slides into the first limiting hole 121 and abuts against the sliding component 322. In this state, the limiting component 321 is located between the second frame 120 and the second rotating shaft mechanism 220. The second frame 120 and the second rotating shaft mechanism 220 can be considered as a whole, and relative rotation cannot occur between the second frame 120 and the second rotating shaft mechanism 220, thereby preventing the second rotating shaft mechanism 220 from driving the third frame 130 to rotate relative to the second frame 120.

[0109] When the first frame 110 and the second frame 120 are in a closed state, the first limiting part 310 is driven by the first frame 110 to be embedded in the first limiting hole 121, thereby pushing the sliding component 322 to slide in the first limiting hole 121. During the sliding process of the sliding component 322, the limiting component 321 can be pushed to slide in the second limiting hole 221 along the second direction and away from the second frame 120, so that the remaining part a2 of the limiting component 321 follows the main body part a1 from the first limiting hole 121 to the second limiting hole 221, thereby making the limiting component 321 completely located in the second rotating shaft mechanism 220, releasing the restriction on the second rotating shaft mechanism 220, so that the second rotating shaft mechanism 220 can drive the third frame 130 to rotate in the direction of the second frame 120.

[0110] In this way, the sliding component 322 and the limiting component 321 slide within the first limiting hole 121 and the second limiting hole 221, thereby enabling the restriction and release of the second rotating shaft mechanism 220. Simultaneously, the limiting component 321 is located within the second rotating shaft mechanism 220, thus not occupying internal space of the frame, and does not affect the battery capacity of the electronic device or the installation space of components within the frame, which is beneficial for rationalizing the layout of the installation space.

[0111] Continue to combine Figure 6 and Figure 7 As shown, the first limiting hole 121 includes a first sub-limiting hole 121a and a second sub-limiting hole 121b that are connected to each other.

[0112] The first sub-restriction hole 121a is formed by the second surface 122 of the second frame 120 being recessed into the interior of the second frame 120 along the first direction.

[0113] The second sub-restricting hole 121b is located at the end of the first sub-restricting hole 121a facing the second restricting hole 221 along the second direction, and the second sub-restricting hole 121b is connected to the second restricting hole 221. That is, the first sub-restricting hole 121a, the second sub-restricting hole 121b and the second restricting hole 221 are arranged sequentially along the second direction.

[0114] The sliding component 322 includes a first sliding member 3221 and a second sliding member 3222 that are in sliding engagement.

[0115] With the first frame 110 and the second frame 120 in a non-closed state, the first slider 3221 and the second slider 3222 are abutted along the first direction and located within the first sub-restriction hole 121a. The remaining portion a2 of the restriction component 321 slides into the second sub-restriction hole 121b and abuts against the second slider 3222. In this state, the restriction component 321 is located within the second frame 120 and the second rotating shaft mechanism 220, restricting the second rotating shaft mechanism 220 from driving the third frame 130 to rotate relative to the second frame 120.

[0116] With the first frame 110 and the second frame 120 in a closed state, the first limiting part 310 is driven by the first frame 110 to be embedded in the first sub-limiting hole 121a. The first limiting part 310 pushes the first sliding member 3221 along a first direction, causing the first sliding member 3221 to slide in the first sub-limiting hole 121a into the second frame 120 along the first direction. This, in turn, pushes the second sliding member 3222 to slide to the right along a second direction into the second sub-limiting hole 121b. The second sliding member 3222 pushes the limiting component 321 to slide to the right along the second direction in the second limiting hole 221, thereby pushing the limiting component 321 so that the remaining part a2 of the limiting component 321 slides to the right from the second sub-limiting hole 121b into the second limiting hole 221, thus releasing the restriction on the second rotating shaft mechanism 220. In this state, the second rotating shaft mechanism 220 can drive the third frame 130 to rotate toward the second frame 120.

[0117] Specifically, the shape of the first sub-restricting hole 121a can match the shape of the first slider 3221, and the shape of the second sub-restricting hole 121b can match the shape of the second slider 3222. For example, the first sub-restricting hole 121a can be a circular hole, and the first slider 3221 can be a cylindrical structure. Alternatively, the first sub-restricting hole 121a can be a square hole, and the first slider 3221 can be a cuboid structure. The cross-sectional dimension of the first sub-restricting hole 121a should be larger than the cross-sectional dimension of the first slider 3221 so that the first slider 3221 can slide within the first sub-restricting hole 121a.

[0118] By providing a connected first sub-restriction hole 121a and a second sub-restriction hole 121b, the force acting on the first slider 3221 in the first direction can be converted into a thrust on the second slider 3222 in the second direction, thereby pushing the restriction assembly 321 to release the restriction on the second rotating shaft mechanism 220. This effectively simplifies the structure of the second restriction part 320, thereby simplifying its installation space and facilitating the miniaturization of electronic devices.

[0119] Figure 8 yes Figure 6 A cross-sectional view along the AA direction.

[0120] See Figure 8 As shown, along the second direction, the width of the first sub-restricting hole 121a is D1, the width of the second sub-restricting hole 121b is D2, the width of the first slider 3221 is L1, and the width of the second slider 3222 is L2. The sum of the widths of the first sub-restricting hole 121a and the second sub-restricting hole 121b, D1+D2, is less than the sum of the widths of the first slider 3221 and the second slider 3222, L1+L2.

[0121] In this way, when the first frame 110 and the second frame 120 are in the closed state, there is a sliding contact between the first slider 3221 and the second slider 3222, which helps to ensure the sliding stability of the first slider 3221 and the second slider 3222 during the process of the first frame 110 and the second frame 120 changing from the closed state to the unfolded state, and effectively ensures the reset of the second slider 3222.

[0122] Combination Figure 7 and Figure 8 As shown, the end of the first slider 3221 facing the second slider 3222 includes a first inclined surface b1, which is inclined in a first direction toward the limiting component 321. The end of the second slider 3222 facing the first slider 3221 includes a second inclined surface b2, which is inclined in a first direction toward the limiting component 321.

[0123] The first inclined surface b1 is parallel to the second inclined surface b2, and the first inclined surface b1 and the second inclined surface b2 slide in cooperation to realize the relative sliding of the first sliding member 3221 and the second sliding member 3222.

[0124] Specifically, the first slider 3221 and the second slider 3222 can slide relative to each other through the first inclined surface b1 and the second inclined surface b2. During the process of the first limiting part 310 pushing the first slider 3221, through the relative sliding of the first inclined surface b1 and the second inclined surface b2, the second slider 3222 can be pushed away from the first slider 3221 in the second direction by the first slider 3221, and the sliding contact surface of the first inclined surface b1 and the second inclined surface b2 gradually decreases.

[0125] In this way, through the cooperation of the first inclined surface b1 and the second inclined surface b2, the thrust in the first direction received by the first sliding member 3221 can be converted into pushing the second sliding member 3222 along the second direction, so as to better realize the sliding cooperation between the first sliding member 3221 and the second sliding member 3222.

[0126] Figure 9 This is a schematic diagram of the structure of a second limiting part provided in an embodiment of this application.

[0127] In a specific implementation, combined with Figure 8 and Figure 9As shown, along a third direction, the size of the second slider 3222 is larger than the size of the first slider 3221, where the third direction is the width direction of the electronic device. It can be understood that the restriction on the rotation of the second pivot mechanism 220 is achieved through the first limiting part 310 and the second limiting part 320. The first limiting part 310 is located in the first frame 110, and the second limiting part 320 is located in the second frame 120. Typically, in a three-fold electronic device, the dimensions of the three bodies along a third direction are different. The size of the first frame 110 is usually smaller than the size of the second frame 120. Thus, there is a preset distance between the first limiting part 310 located on the first frame 110 and the second pivot mechanism 220. To better achieve the sliding engagement of the first limiting part 310 with the second limiting part 320 and to shorten the limiting path between the first limiting part 310 and the second limiting part 320, a wider second slider 3222 can be provided.

[0128] The second slider 3222 can be a slider structure with an inclined surface and a groove in the middle, thereby reducing the overall weight of the second slider 3222 and avoiding the situation where the first slider 3221 is difficult to push due to the excessive weight of the second slider 3222. The sliding mating surface between the second slider 3222 and the first slider 3221 is the second inclined surface b2, and the back surface of the second slider 3222 (not shown in the figure) is the sliding mating surface with the first limiting member 3211.

[0129] Of course, in the other three-fold structure electronics, when the dimensions of the first frame 110 and the second frame 120 along the third direction are the same, the second slider 3222 can be set to have the same structure as the first slider 3221. In the non-closed state of the first frame 110 and the second frame 120, the first slider 3221 and the second slider 3222 can be understood as two identical and inverted sliding blocks.

[0130] In some feasible implementation methods, continue to combine Figure 7 and Figure 8 As shown, the limiting component 321 also includes a first elastic member 3212, which is sleeved on the main body portion a1 of the first limiting member 3211, and the first elastic member 3212 moves away from the second sliding member 3222 along the second direction.

[0131] When the first frame 110 and the second frame 120 are in a non-closed state, the remaining part a2 of the first limiting member 3211 slides into the second sub-limiting hole 121b and abuts against the second sliding member 3222. The main body part a1 of the first limiting member 3211 is disposed in the second limiting hole 221 through the first elastic member 3212, and the first elastic member 3212 is in its initial form.

[0132] When the first frame 110 and the second frame 120 are in a closed state, the first limiting member 3211 is pushed by the second sliding member 3222 to slide to the right in the second direction, squeezing the first elastic member 3212 and changing from the initial state to the compressed state.

[0133] Thus, after the thrust acting on the first limiting member 3211 disappears, the first elastic member 3212 can recover its elastic deformation, achieving the reset of the first limiting member 3211. That is, when the first frame 110 and the second frame 120 change from the closed state to the unfolded state, the first limiting part 310 no longer applies a thrust to the sliding component 322, the force on the first sliding member 3221 disappears, and consequently the force on the first limiting member 3211 disappears. The first elastic member 3212 is no longer compressed and returns from the compressed state to the initial state, pushing the first limiting member 3211 to slide to the left along the second direction, and the remaining part a2 slides to the second sub-limiting hole 121b, thereby pushing the second sliding member 3222 to slide to the left from the second sub-limiting hole 121b to the first sub-limiting hole 121a. The first sliding member 3221 slides upward along the first direction, and the second limiting part 320 returns to the state where it is not driven by the first limiting part 310.

[0134] In one specific implementation, the first elastic element 3212 can be a spring. Springs have a simple structure, are easy to install, and do not occupy installation space.

[0135] Continue to combine Figure 7 and Figure 8 As shown, the first limiting member 3211 may include an annular protrusion a3, which is arranged around the outer surface of the first limiting member 3211 and can extend along a second direction on the outer surface of the first limiting member 3211. The first elastic member 3212 is sleeved on the outside of the first limiting member 3211, with one end connected to the annular protrusion a3 and the other end abutting against the bottom surface of the second limiting hole 221.

[0136] The inner surface of the second limiting hole 221 includes an annular groove 222, and an annular protrusion a3 is embedded in the annular groove 222. Along the second direction, the length of the annular groove 222 is greater than the length of the annular protrusion a3. This ensures that the annular protrusion a3 can reciprocate within the annular groove 222 along the second direction towards or away from the first limiting hole 121.

[0137] In this way, the reciprocating motion of the annular protrusion a3 within the annular groove 222 restricts the movement path of the annular protrusion a3 along the second direction, preventing the first limiting member 3211 from dislodging during movement along the second direction, thereby ensuring the stability of the restriction on the second rotating shaft mechanism 220 and the restriction release operation.

[0138] See also the following for some feasible implementation methods. Figure 7 and Figure 8 As shown, the annular protrusion a3 includes a first end face a31 and a second end face a32 that are opposite to each other along the second direction, and the annular groove 222 includes a third end face c1 and a fourth end face c2 that are opposite to each other along the second direction.

[0139] In the non-closed state of the first frame 110 and the second frame 120, the first end face a31 of the annular protrusion a3 abuts against the third end face c1 of the annular groove 222, and the second end face a32 of the annular protrusion a3 and the fourth end face c2 of the annular groove 222 may have a first distance L.

[0140] During the process of the first frame 110 rotating toward the second frame 120 and being in a closed state with the second frame 120, the second slider 3222 pushes the first elastic member 3212 to move along the second direction. The first restrictor 3211 is pushed by the second slider 3222 to move away from the first restricting hole 121. The annular protrusion a3 of the first restrictor 3211 is driven by the first restrictor 3211 and moves synchronously within the annular groove 222 away from the first restricting hole 121. During this process, the first end face a31 of the annular protrusion a3 gradually moves away from the third end face c1 of the annular groove 222, and the second end face a32 gradually moves closer to the fourth end face c2. The first elastic member 3212 is continuously compressed. Until the first frame 110 and the second frame 120 are in a closed state, the second end face a32 of the annular protrusion a3 abuts against the fourth end face c2 of the annular groove 222, and the first end face a31 and the third end face c1 can have a first distance L, and the first elastic member 3212 is in a compressed state.

[0141] After the thrust of the second slider 3222 on the first elastic member 12 disappears, the first elastic member 3212 recovers its elastic deformation. The first elastic member 3212 pushes the annular protrusion a3, causing the annular protrusion a3 to move in the annular groove 222 toward the direction of approaching the first limiting hole 121, thereby pushing the first limiting member 3211 toward the direction of approaching the first limiting hole 121, until the first elastic member 3212 returns to its initial shape. The remaining part a2 of the first limiting member 3211 is located in the second sub-limiting hole 121b, thereby pushing the second slider 3222 to slide to the first sub-limiting hole 121a.

[0142] The annular protrusion a3 can move a distance L along the second direction within the annular groove 222. The specific value of L can be adaptively adjusted according to the overall size of the electronic device. By limiting the movement distance of the annular protrusion a3 to L, the stability of the annular protrusion a3 during reciprocating motion can be ensured, thereby ensuring the stability of the restriction on the second rotating shaft mechanism 220 and the restriction release operation.

[0143] To facilitate understanding of the frame restriction order in the electronic device provided in the embodiments of this application, combined with Figure 7 and Figure 8 The state of the first limiting mechanism and the third frame 130 during the rotation of the first frame 110 is described.

[0144] When the first frame 110 does not rotate toward the second frame 120, or when the first frame 110 rotates toward the second frame 120 and is in a non-closed state with the second frame 120, the second limiting part 320 is located in the second frame 120 and the second rotating shaft mechanism 220, thereby limiting the second rotating shaft mechanism 220 from driving the third frame 130 to rotate toward the second frame 120.

[0145] After the first frame 110 drives the first limiting part 310 to rotate to abut against the first sliding member 3221, the first limiting part 310 presses the first sliding member 3221 along the first direction, and the first sliding member 3221 slides along the first direction, thereby pushing the second sliding member 3222 to move along the second direction from the first sub-limiting hole 121a toward the second sub-limiting hole 121b, thereby pushing the first limiting member 3211 located in the second sub-limiting hole 121b. The first limiting member 3211 moves along the second direction away from the second sub-limiting hole 121b until the first frame 110 and the second frame 120 are in a closed state, and the remaining part a2 of the first limiting member 3211 completely moves into the second limiting hole 221. The first elastic member 3212 is in a compressed state. At this time, the second rotating shaft mechanism 220 can drive the third frame 130 to rotate toward the second frame 120.

[0146] It is worth noting that the first limiting part 310 can be disposed at one end of the electronic device along the second direction. Of course, there can be multiple first limiting parts 310, which can be disposed at opposite ends of the electronic device along the second direction.

[0147] Figure 10 This is a schematic diagram of a structure provided in an embodiment of this application when the first frame is not locked to the second frame; Figure 11 This is a schematic diagram of the structure provided in this application embodiment when the first frame is locked into the second frame.

[0148] Combination Figure 10 and Figure 11 As shown, the electronic device also includes a first locking mechanism for locking the first frame 110 into the second frame 120.

[0149] The first locking mechanism includes a first locking part 410 and a second locking part. The first locking part 410 is disposed on the first frame 110, and the second locking part is disposed on the second rotating shaft mechanism 220. The second locking part may be disposed on the connecting block of the second rotating shaft mechanism 220.

[0150] When the first frame 110 and the second frame 120 are in the closed state, the first locking part 410 is configured to slide with the second locking part to lock the first frame 110 into the second frame 120. When the first frame 110 and the second frame 120 are in the open state, the first locking part 410 is configured to slide with the second locking part to separate the first frame 110 from the second frame 120.

[0151] Specifically, when the first frame 110 and the second frame 120 are in the closed state, the first locking part 410 can slide towards the second locking part, thereby achieving locking between the first frame 110 and the second frame 120 through their sliding engagement, improving the operability of the electronic device. When it is necessary to separate the first frame 110 and the second frame 120, the first locking part 410 can move away from the second locking part to achieve separation of the first frame 110 and the second frame 120.

[0152] In this way, the first frame 110 can be locked or unlocked as needed, realizing the ease of use of the electronic device and improving its operability.

[0153] Figure 12 yes Figure 10 Cross-sectional view along the BB direction; Figure 13 yes Figure 11 A cross-sectional view along the CC direction.

[0154] Combination Figure 12 and Figure 13 As shown, the first frame 110 includes a first slide groove 112 and a second slide groove 113 that are connected. The first slide groove 112 is connected to the external environment, and the second slide groove 113 is located at the end of the first slide groove 112 that is away from the external environment along the second direction.

[0155] The first groove 112 can be L-shaped, including a horizontal groove extending along a second direction and a vertical groove extending along a first direction. The structures of the horizontal and vertical grooves are not shown in the figure. The horizontal groove connects to the external environment through the third surface of the first frame 110, and the vertical groove extends along the first direction, with the end of the vertical groove opposite to the external environment connected to the end of the horizontal groove. The third surface can be a surface that is connected to and perpendicular to the first surface 111, extending along the width direction of the electronic device.

[0156] The first locking part 410 includes a first locking member 411 and a second locking member 412.

[0157] The first locking member 411 is slidably disposed within the first slide groove 112, with one end protruding from the first slide groove 112 into the external environment. The first locking member 411 is configured such that when subjected to a force in a first direction, the first locking member 411 can slide within the first slide groove 112 along the first direction.

[0158] The first locking member 411 can be L-shaped, including a horizontal bar extending along a second direction and a vertical bar extending along a first direction. The structures of the horizontal bar and the vertical bar are not shown in the figure. The horizontal bar is slidably disposed in a horizontal groove, and one end of the horizontal bar communicates with the outside through the horizontal groove. The part of the horizontal bar that communicates with the outside can be actuated and can move along the first direction. The vertical bar is slidably disposed in a vertical groove, and one end of the vertical bar is connected to the horizontal bar. The vertical bar is configured to slide in the vertical groove along the first direction synchronously driven by the horizontal bar.

[0159] In this configuration, the height of the transverse groove is greater than the height of the transverse bar along the first direction, so that when the first locking member 411 is moved, the transverse bar can slide within the transverse groove along the first direction.

[0160] The second locking member 412 is slidably disposed in the second slide groove 113, the second slide groove 113 extends along the second direction, one end of the second locking member 412 protrudes from the first surface 111 of the first frame 110 and extends toward the second locking part 420.

[0161] The first direction may include a first sub-direction z1 and a second sub-direction z2. The first sub-direction z1 is the direction extending from the first frame 110 to the second frame 120. For example, when it is necessary to lock the first frame 110 and the second frame 120, the first locking member 411 is moved along the first sub-direction to the end located in the external environment. The first locking member 411 slides close to the second frame 120 in the first slide groove 112 along the first sub-direction z1. The first locking member 411 can push the second locking member 412. The second locking member 412 can slide along the second direction toward the second locking part 420 until the second locking member 412 slides completely into the second locking part 420, so that the first frame 110, the second frame 120 and the second rotating shaft mechanism 210 can be regarded as an integral structure. The first frame 110 cannot rotate relative to the second frame 120, thereby locking the first frame 110 onto the second frame 120.

[0162] For example, when it is necessary to separate the first frame 110 and the second frame 12, the end of the first locking member 411 located in the external environment is moved along the second sub-direction z2. The first locking member 411 moves away from the second frame 120 in the first slide groove 112 along the second sub-direction z2. The pushing force of the first locking member 411 on the second locking member 412 is reduced. The second locking member 412 gradually moves away from the second locking part 420 along the second direction until the second locking member 412 is completely disengaged from the second locking part 420, thereby realizing the separation of the first frame 110 and the second frame 120.

[0163] In this way, the locking and unlocking of the first frame 110 and the second frame 120 can be achieved by moving the first locking member 411 at the end located in the external environment, which is simple to operate.

[0164] See also Figure 12 and Figure 13 As shown, the second locking part 420 includes a third sliding groove 421 and a fourth sliding groove 422 that are connected. The third sliding groove 421 is formed by the surface of the second rotating shaft mechanism 220 being recessed inward along a first direction. One end of the fourth sliding groove 422 is connected to the third sliding groove 421, and the other end extends inward toward the second rotating shaft mechanism 220 along a second direction relative to the third sliding groove 421. The second rotating shaft mechanism 220 may include a connecting block and a rotating shaft assembly (the corresponding structures are not shown in the figure). The connecting block is used to connect the frame (such as the second frame 120 and the third frame 130), and the rotating shaft assembly is used to drive the frame to rotate. The second locking part 420 may be disposed on the connecting block. In this way, the second locking part 420 is disposed within the second rotating shaft mechanism 220, without occupying the internal installation space of the frame, and without affecting the battery capacity or the space of the internal components of the frame.

[0165] When the first frame 110 rotates to a closed state with the second frame 120, the protruding end of the second locking member 412 can be embedded in the third sliding groove 421. The second locking member 412 is configured to slide in the second direction when the first locking member 411 slides in the first direction. The protruding end of the second locking member 412 can move into the fourth sliding groove 422, thereby locking the first frame 110 into the second frame 120. The protruding end of the second locking member 412 can be a first latch 4123 extending in the second direction, and the cross-sectional shape of the first latch 4123 and the fourth sliding groove 422 can be the same. The second locking member 412 also includes a first locking rod 4121 and a first follower wheel 4122.

[0166] The first locking rod 4121 extends along the first direction and is slidably disposed within the second slide groove 113.

[0167] The first follower wheel 4122 is disposed on the first locking rod 4121. The first locking member 411 includes a first end 4111 that slides with the second locking part 420 and a second end 4112 that extends to the external environment. The first follower wheel 4122 abuts against the first end 4111 of the first locking member 411. During the process of the first locking member 411 pushing the second locking member 412 to move, the first end 4111 can slide with the first follower wheel 4122.

[0168] Thus, with the first frame 110 and the second frame 120 in a closed state, the first latch 4123 is driven by the first frame 110 to engage with the third slide groove 421. In this state, the first latch 4123 is opposite to the fourth slide groove 422. When the first locking member 411 is subjected to a force in the first direction, the first follower wheel 4122 can be configured to be subjected to a force from the first locking member 411 in the first direction, pushing the first locking rod 4121 to slide in the second direction, thereby driving the first latch 4123 to engage with the fourth slide groove 422, effectively simplifying the engagement of the first locking member 411 and the second locking member 412.

[0169] For example, when the first frame 110 and the second frame 120 are in a closed state, when the first locking member 411 is subjected to a force in the first sub-direction z1, the first locking member 411 can slide along the first sub-direction z1 toward the direction closer to the second frame 120. The first locking member 411 pushes the first follower wheel 4122 to slide along the second direction. The first follower wheel 4122 slides with the first locking member 411, thereby pushing the first locking rod 4121 to slide along the second direction. The first latch 4123 is driven to be embedded into the fourth slide groove 422 along the second direction, so as to realize the locking of the first frame 110 and the second frame 120.

[0170] For example, when the first frame 110 and the second frame 120 are in a closed state, when the first locking member 411 is subjected to a force in the second sub-direction z2, the first locking member 411 slides away from the second frame 120 along the second sub-direction z2, the thrust acting on the first follower wheel 4122 is weakened, the first locking rod 4121 slides along the second direction, and the first latch 4123 is driven to slide out of the fourth slide groove 422 along the second direction. In this state, the first frame 110 can rotate relative to the second frame 120, thereby separating the first frame 110 from the second frame 120.

[0171] In this way, the cooperation between the first latch 4123 and the fourth slide groove 422 eliminates the need for additional locking components, effectively simplifying the sliding cooperation between the first locking part 410 and the second locking part 420. Furthermore, the elimination of additional connecting components facilitates the miniaturization of electronic devices and effectively simplifies the locking operation of the first frame 110 and the second frame 120.

[0172] In some feasible implementations, the first end 4111 of the first locking member 411 that abuts against the second locking member 412 may include a third inclined surface 4113, which may be inclined in a first direction toward the second locking member 412. The second locking member 412 may include a fourth inclined surface (not shown in the figure), which may be inclined in a first direction toward the second locking member 412.

[0173] The third inclined surface 4113 is configured to slide in conjunction with the fourth inclined surface to achieve sliding of the second locking member 412 relative to the first locking member 411. Alternatively, the third inclined surface 4113 can also be configured to cooperate with the first follower wheel 4122 to achieve sliding of the second locking member 412 relative to the first locking member 411. This increases the versatility of the sliding cooperation between the first locking member 411 and the second locking member 412.

[0174] It is worth noting that when the first locking member 411 includes the third inclined surface 4113, the second locking member 412 may not include the first follower wheel 4122. In this case, the second locking member 412 may be a connecting block including a fourth inclined surface.

[0175] See also Figure 12 and Figure 13 As shown, the first frame 110 also includes a fifth slide groove 114, which is connected to the second slide groove 113, and the length direction of the fifth slide groove 114 is parallel to the second direction.

[0176] The second locking member 412 also includes a second elastic member 4124, which is located in the fifth slide groove 114. One end of the second elastic member 4124 is connected to the first locking rod 4121, and the other end is connected to the first frame 110.

[0177] When the first frame 110 and the second frame 120 are in a non-closed state and the first frame 110 is not locked to the second frame 120, the first locking rod 4121 is close to the first locking member 411, the first locking member 411 is not subjected to any force, and the second elastic member 4124 is in its initial state.

[0178] When the first frame 110 and the second frame 120 are in a closed state, and the first locking member 411 slides along the first sub-direction z1 under force, the first locking member 411 pushes the second locking member 412 to slide along the second direction. The distance between the first locking rod 4121 and the first locking member 411 increases, gradually moving away from the first locking member 411 and compressing the second elastic member 4124, causing the second elastic member 4124 to be in a compressed state. The first locking rod 4121 may include a third end and a fourth end. The third end may be connected to the second elastic member 4124. During the process of the first locking member 411 pushing the second locking member 412, the third end can push the second elastic member 4124, causing the second elastic member 4124 to be in a compressed state. The fourth end can extend along the second direction and form a first latch 4123.

[0179] When the first locking member 411 slides along the second sub-direction z2 under force, the thrust of the first locking member 411 on the second locking member 412 weakens, the second elastic member 4124 recovers its elastic deformation, pushes the first locking rod 4121, and thus causes the first latch 4123 to gradually disengage from the fourth slide groove 422. Until the second elastic member 4124 returns to its initial shape, the first latch 4123 is completely disengaged from the fourth slide groove 422, and the first frame 110 and the second frame 120 are in a closed and separated state.

[0180] In this way, by setting the second elastic element 4124, the elasticity of the second elastic element 4124 can assist the first locking element 411 in resetting during the unlocking process of the first frame 110, thus avoiding jamming during the operation of the first locking element 411.

[0181] To facilitate understanding of the first locking mechanism in the embodiments of this application, combined with Figure 11 and Figure 12 The cooperation process of the first locking member 411 and the second locking member 412 is described.

[0182] When the first frame 110 and the second frame 120 are in the closed state, the first latch 4123 is inserted into the third slide groove 421 as the first frame 110 rotates toward the second frame 120. When the first locking member 411 is subjected to a force along the first sub-direction z1, the first locking member 411 moves closer to the second frame 120 along the first sub-direction z1 in the first slide groove 112. The third inclined surface 4113 of the first locking member 411 slides and engages with the first follower wheel 4122 or the fourth inclined surface of the second locking member 412, thereby pushing the first locking rod 4121 away from the first locking member 411 along the second direction in the second slide groove 113. The third end of the second locking member 412 presses the second elastic member 4124, and the second elastic member 4124 is in a compressed state. The first latch 4123 of the second locking member 412 moves along the second direction to the fourth slide groove 422 within the third slide groove 421, thereby locking the first frame 110 and the second frame 120 together.

[0183] When the first locking member 411 is subjected to a force along the second sub-direction z2, the first locking member 411 moves away from the second frame 120 along the second sub-direction z2 within the first slide groove 112. The thrust of the first locking member 411 on the first follower wheel 4122 or the fourth inclined surface is reduced. The first locking rod 4121 moves closer to the first locking member 411 along the second direction within the second slide groove 113. The pressure of the third end of the second locking member 412 on the second elastic member 4124 is reduced, and the second elastic member 4124 recovers its elastic deformation. The first latch 4123 of the second locking member 412 slides from the fourth slide groove 422 to the third slide groove 421 along the second direction, thereby separating the first frame 110 from the second frame 120.

[0184] In some feasible implementations, the electronic device may simultaneously include a first locking mechanism and a first limiting mechanism, which, when the first frame 110 and the second frame 120 are not closed, restricts the rotation of the second rotating shaft mechanism. When the first frame 110 and the second frame 120 are closed, the locking of the first frame 110 and the second frame 120 is simultaneously achieved, and the rotation restriction of the second rotating shaft mechanism 210 is released.

[0185] In one implementation, the first locking mechanism and the first limiting mechanism can be disposed at opposite ends of the electronic device along the second direction. In this scenario, the first locking mechanism can be disposed within the frame of the first housing 110 itself, without occupying the mounting space of the first housing 110 along the first direction. This allows for the utilization of the mounting space of the electronic device in the second direction, enabling the first and second locking mechanisms to be rationally configured, thus ensuring balanced force distribution on both sides of the electronic device along the second direction.

[0186] In another implementation, the first locking mechanism and the first limiting mechanism are spaced apart and disposed on the same end of the electronic device. In this scenario, the first locking mechanism can also be disposed on a protruding structure of the first frame 110. The first frame 110 has a protruding structure extending along a first direction, which can be at the same height as the first limiting part 310. The protruding structure of the first frame 110 is flush with the first limiting part 310 along a second direction, which is beneficial for balancing the forces on the first frame 110 and the second frame 120.

[0187] In another implementation, the first limiting mechanism and the first locking mechanism can be located at the same end of the electronic device, with the first locking mechanism located within the first limiting portion 310 of the first frame 110. In this scenario, the width of the first limiting portion 310 is increased, with a portion of the first limiting portion 310 accommodating the first locking portion 410 and the other portion sliding in cooperation with the sliding assembly 322. In this scenario, when the first frame 110 and the second frame 120 are in an open state, the first limiting portion 310 cooperates with the sliding assembly 322 to restrict the second rotating shaft mechanism 220. When the first frame 110 rotates to a closed state with the second frame 120, the first limiting portion 310 pushes the sliding assembly 322, thereby pushing the limiting assembly 321 to release the restriction on the second rotating shaft mechanism 220. The first locking portion 410 within the first limiting portion 310 can also cooperate with the second locking portion 420 within the second rotating shaft mechanism 420 to lock the first frame 110 into the second frame 120.

[0188] In this way, the first locking mechanism and the first limiting part 310 can be integrated together, further reducing the installation space of the first locking mechanism and facilitating the miniaturization of electronic devices.

[0189] Alternatively, to ensure balanced force distribution on the first frame 110 and the second frame 120, and to avoid unilateral force distribution on the first frame 110, the number of first limiting mechanisms can be two, and the number of first locking mechanisms can be one. Along the second direction, one first limiting mechanism and one first locking mechanism are disposed at the same end of the electronic device, and another first limiting mechanism can be disposed at the other end of the electronic device.

[0190] In the above implementation, when the first frame 110 and the second frame 120 are in a non-closed state, the second limiting part 320 restricts the second rotating shaft mechanism 220, preventing the third frame 130 from rotating towards the second frame 120. Furthermore, the cooperation of the first locking part 410 and the second locking part 420 separates the first frame 110 and the second frame 120. When the first frame 110 rotates to a closed state with the second frame 120, the cooperation of the first limiting part 310 and the second limiting part 320 releases the restriction on the second rotating shaft mechanism 220, allowing the second rotating shaft mechanism 220 to drive the third frame 130 to rotate towards the second frame 120. Additionally, after being subjected to a force in the first direction, the first locking part 410 can move into the second locking part 420, locking the first frame 110 and the second frame 120 together. It is worth noting that the specific configuration of the first limiting mechanism and the first locking mechanism can be adaptively adjusted according to the size of the electronic device. For example, when the size of the electronic device along the first direction is large, the first locking mechanism can be disposed within the frame of the first frame 110 itself. When the size of the electronic device along the first direction is small, the first locking mechanism can be disposed within the first limiting part 310, and the second limiting part 320 and the second locking member 412 are disposed along a third direction, which is the width direction of the electronic device.

[0191] In one specific implementation, the first rotating shaft mechanism 210 is also provided with a damping element, so that after the first frame 110 and the second frame 120 are unlocked by the first locking mechanism, the damping element on the first rotating shaft mechanism 210 can drive the first frame 110 to bounce at a preset angle away from the second frame 120, thereby forming a handle position so as to rotate the first frame 110.

[0192] Figure 14 This is a schematic diagram of the structure of another electronic device provided in an embodiment of this application.

[0193] This application embodiment also provides another electronic device, which includes a first frame 110, a second frame 120, a third frame 130, a first rotating shaft mechanism 210, a second rotating shaft mechanism 220, a limiting and locking integrated member 330, a third limiting part 340, and a second locking mechanism.

[0194] The first frame 110 and the second frame 120 are rotatably disposed on opposite sides of the first rotating shaft mechanism 210, and the second frame 120 and the third frame 130 are rotatably disposed on opposite sides of the second rotating shaft mechanism 220.

[0195] The second locking mechanism includes a third locking part and a fourth locking part. The third locking part is located in the first frame 110, and the fourth locking part is located in the second rotating shaft mechanism 220.

[0196] The locking component 330 is disposed in the first frame 110, and the third limiting part is disposed in the second frame 120 and the second rotating shaft mechanism 220.

[0197] When the first frame 110 and the second frame 120 are in the open state, the locking member 330 is configured to cooperate with the third limiting part to prevent the second rotating shaft mechanism 220 from driving the third frame 130 to rotate relative to the second frame 120. The locking member 330 is also configured to cooperate with the third locking part and the fourth locking part to separate the first frame 110 from the second frame 120.

[0198] With the first frame 110 and the second frame 120 in a closed state, the locking member 330 is also configured to cooperate with the third limiting part, allowing the second rotating shaft mechanism 220 to drive the third frame 130 to rotate toward the second frame 120. Furthermore, the locking member 330 is also configured to cooperate with the third locking part and the fourth locking part to lock the first frame 110 into the second frame 120.

[0199] In this way, by setting the limiting locking component 330, not only can the rotation sequence of the frame be restricted, but a locking function can also be achieved. This simplifies the structure, enhances the ease of use of the electronic device, and effectively improves its operability and reliability.

[0200] Figure 15 This is a schematic diagram of the structure of a locking integrated component provided in an embodiment of this application.

[0201] See Figure 15 As shown, the locking component 330 includes a first portion 331, a second portion 332, and a third portion 333. The first portion 331 extends along a second direction and protrudes at one end into the external environment, and can slide within the first frame 110 along the first direction. The second portion 332 and the third portion 333 both extend along the first direction and are respectively disposed at the end of the first portion 331 facing away from the external environment. The second portion 332 and the third portion 333 are disposed along a third direction, which is perpendicular to the first direction and the second direction, and the third direction is the width direction of the electronic device.

[0202] The second part 332 and the third part 333 can be separate structures, spaced apart along a third direction. In this implementation, the size of the second part 332 is larger than the size of the third part 333. It is understandable that the force between the second part 332 and the third locking part is a sliding engagement in the second direction, requiring the second part to push the third locking part and change the direction of the force through its own inclined surface. However, the force between the third part 333 and the third limiting part is along the first direction and does not change the direction of the force. Therefore, the force exerted by the third part 333 on the third locking part is greater. The third part 333 can be made larger than the second part 332 to meet the sliding requirements of the third part 333 on the third locking part. Simultaneously, the second part 332 and the third part 333 can also be staggered along a third direction, thus avoiding the same force being applied to the same position on the second frame 120 along the third direction. Distributing the force across the positions helps ensure the mechanical performance of the second frame 120.

[0203] Of course, in other specific implementations, the size and positional relationship between the third part 333 and the second part 332 can be flexibly adjusted according to the size of the electronic device.

[0204] In another specific implementation, the second part 332 and the third part 333 can also be integrally molded. Integral molding can ensure the overall stability of the locking component 330.

[0205] In this way, the second part 332 and the third part 333 can be set up more flexibly. Of course, in other feasible implementation methods, the specific form of the second part 332 and the third part 333 can also be adapted to the installation situation of the locking unit 330.

[0206] Figure 16 This is a schematic diagram of the structure of a sixth slide groove provided in an embodiment of this application.

[0207] Combination Figure 15 and Figure 16 As shown, the first frame 110 includes a connected sixth slide groove 116. The sixth slide groove 116 extends along a first direction and communicates with the external environment. A limiting locking member 330 is slidably disposed in the sixth slide groove 116, and one end protrudes from the sixth slide groove 116 to the external environment. The limiting locking member 330 is configured to slide in the sixth slide groove 116 along the first direction when subjected to a force in the first direction, which is the thickness direction of the electronic device.

[0208] Specifically, the sixth slide 116 includes a first sub-slide 116a, a second sub-slide 116b, and a third sub-slide 116c that are connected to each other. The first sub-slide 116a extends along a second direction and communicates with the external environment. The second sub-slide 116b and the third sub-slide 116c extend along a first direction and are located at the end of the first sub-slide 116a that is away from the external environment. The second sub-slide 116b and the third sub-slide 116c are arranged along a third direction. A first portion 331 is slidably disposed in the first sub-slide 116a, a second portion 332 is slidably disposed in the second sub-slide 116b, and a third portion 333 is slidably disposed in the third sub-slide 116c.

[0209] When the first frame 110 and the second frame 120 are in a closed state, and the first part 331 is subjected to a force in the first direction, it can simultaneously drive the second part 332 and the third part 333 to move along the first direction.

[0210] The second sub-slide groove 116b penetrates the first surface 111. During the sliding of the locking and restraining integral 330 along the first direction, the second part 332 is driven by the first part 331 to extend out of the second sub-slide groove 116b and act on the third restraining part 340, thereby achieving a sliding engagement with the third restraining part 340. The third part 333 is simultaneously driven by the first part 331 to engage with the third locking part and the fourth locking part, thereby achieving the locking of the first frame 110 and the second frame 120.

[0211] In this way, when the locking unit 330 does not move in the first direction, the third part 333 is located inside the first frame 110 and does not extend out of the first surface 111. On the one hand, it does not occupy the installation space of the first surface 111. On the other hand, the second part 332 can easily cooperate with the third limiting part 340 by extending out of the second sub-slide groove 116b.

[0212] The first direction may include a first sub-direction z1 and a second sub-direction z2. The first sub-direction z1 may be a direction along the first frame 110 to the second frame 120 when the first frame 110 and the second frame 120 are in a closed state. The second sub-direction z2 may be a direction along the second frame 120 to the first frame 110 when the first frame 110 and the second frame 120 are in a closed state.

[0213] When the first frame 110 and the second frame 120 are closed, the first part 331 is configured to simultaneously drive the second part 332 and the third part 333 to move along the first sub-direction z1 when subjected to a force in the first sub-direction z1. The second part 332 abuts against the third limiting part 340 and is configured to cooperate with the third limiting part 340, allowing the second rotating shaft mechanism 220 to drive the third frame 130 to rotate toward the second frame 120. The third part 333 abuts against the third locking part and is configured to cooperate with the third locking part and the fourth locking part, locking the first frame 110 into the second frame 120.

[0214] When the first frame 110 and the second frame 120 are closed, the first part 331 is configured to simultaneously drive the second part 332 and the third part 333 to move along the second sub-direction z2 when subjected to a force in the second sub-direction z2. The second part 332 moves away from the third limiting part 340 along the second direction and is configured to cooperate with the third limiting part 340 to prevent the second rotating shaft mechanism 220 from driving the third frame 130 to rotate relative to the second frame 120. The third part 333 is configured to cooperate with the third locking part and the fourth locking part to separate the first frame 110 and the second frame 120.

[0215] The first part 331 can simultaneously drive the second part 332 and the third part 333 to cooperate with the third limiting part and the third locking part, respectively. In this way, by moving the first part 331, the limiting and locking member 330 can simultaneously realize the limiting of the second rotating shaft mechanism 220 and the locking and unlocking of the first frame 110, which is simple to operate. It helps to simplify the structure of the limiting and locking integrated member 330.

[0216] Figure 17 This is a schematic diagram of a structure for limiting and locking an integral component when it is not under force, provided in an embodiment of this application; Figure 18 This is a schematic diagram of a structure that restricts the movement of a locking component under force along a first direction, as provided in an embodiment of this application.

[0217] Combination Figure 17 and Figure 18 As shown, the first frame 110 may also be provided with a seventh slide groove 117. The seventh slide groove 117 extends along the second direction and is located at the end of the third sub-slide groove 116c opposite to the first sub-slide groove 116a, and the seventh slide groove 117 communicates with the third sub-slide groove 116c. The third locking part 430 is slidably disposed in the seventh slide groove 117. One end of the third locking part 430 protrudes from the first surface 111 of the first frame 110 and extends toward the direction of the fourth locking part 440. The first surface 111 faces the second frame 120 in the closed state.

[0218] In this way, when the locking component 330 is subjected to a force in the first direction, the locking component 330 can slide and engage with the third locking part 430 in the first direction, and the third locking part 430 can move toward the fourth locking part 440 until the third locking part 430 moves into the fourth locking part 440, thereby achieving the locking of the first frame 110 and the second frame 120.

[0219] The locking component 330 can be L-shaped. The sixth slide groove 116 can also be L-shaped, and the height of the slide groove of the horizontal portion of the sixth slide groove 116 along the first direction is greater than the height of the horizontal portion of the locking component 330, so that the horizontal portion of the locking component 330 is slidably disposed in the slide groove of the horizontal portion of the sixth slide groove 116.

[0220] The fourth locking part 440 includes an eighth slide groove 441 and a ninth slide groove 442 that are connected to each other. The eighth slide groove 441 is formed by the surface of the second rotating shaft mechanism 220 being recessed inward along a first direction. One end of the ninth slide groove 442 is connected to the eighth slide groove 441, and the other end extends towards the interior of the second rotating shaft mechanism 220 along a second direction relative to the eighth slide groove 441. The second direction is the length direction of the electronic device.

[0221] When the first frame 110 and the second frame 120 are in a closed state, the protruding end of the third locking part 430 is driven by the first frame 110 to be embedded into the eighth slide groove 441. When the locking member 330 slides along the first direction, the protruding end of the third locking part 430 is driven by the sliding of the locking member 330 and slides along the second direction. The protruding end of the third locking part 430 moves along the second direction from the eighth slide groove 441 to the ninth slide groove 442, thereby locking the first frame 110 and the second frame 120. The protruding end of the third locking part 430 can be a second latch 433 extending along the second direction. The cross-sectional shape of the second latch 433 and the ninth slide groove 442 can be the same. The third locking part can also include a second locking rod 431 and a second follower wheel 432.

[0222] The second locking rod 431 extends along the first direction and is slidably disposed within the seventh slide groove 117.

[0223] The second follower wheel 432 is disposed on the second locking rod 431, and the second follower wheel 432 abuts against one end of the limiting locking integral member 330; the second latch 433 is disposed on one end of the second locking rod 431 that protrudes from the first surface 111, and the second latch 433 extends along the second direction; in the closed state, the second latch 433 is embedded in the eighth slide groove 441, and the second follower wheel 432 is configured to be subjected to the force of the second locking member 412 along the first direction, pushing the second locking rod 431 to move along the second direction, thereby driving the second latch 433 to be embedded in the ninth slide groove 442.

[0224] The first frame 110 also includes a fifth slide groove 114, which is connected to the seventh slide groove 117. The length direction of the fifth slide groove 114 is parallel to the second direction. The third locking part 430 also includes a third elastic member 434, which is located in the fifth slide groove 114. One end of the third elastic member 434 is connected to the second locking rod 431, and the other end is connected to the first frame 110. In the non-closed state, the second locking rod 431 is close to the limiting locking integral member 330, and the third elastic member 434 is in its initial state. In the closed state, the second locking rod 431 slides along the second direction and moves away from the limiting locking integral member 330, pressing the third elastic member 434, and the third elastic member 434 is in a compressed state. The end of the locking member 330 that abuts against the third locking part 430 includes a seventh inclined surface 334, which is inclined in a first direction toward the third locking part 430. The third locking part 430 includes an inclined surface, which is inclined in a first direction toward the locking member 330. The seventh inclined surface 334 is configured to slide in cooperation with the inclined surface of the third locking part 430, or to slide in cooperation with the second follower wheel 432, so as to realize the sliding of the third locking part 430 relative to the locking member 330.

[0225] In this way, by cooperating with the second latch 433 and the ninth slide groove 442, no additional locking components are required, which effectively simplifies the locking operation of the first frame 110 and the second frame 120.

[0226] Continue to combine Figure 17 and Figure 18 As shown, the electronic device also includes a boss 510, which is located on the first surface 111 of the first frame 110 and extends along a first direction.

[0227] The second part 332 can be disposed outside the boss 510, and the third part 333 can be disposed inside the boss 510. The third sub-slide 116c extends from the first frame 110 to the boss 510, and the third part 333 slides within the boss 510 in a first direction via the third sub-slide 116c. The second part 332 is disposed outside the boss 510, and during sliding, the second part 332 can extend out of the first frame 110 and be located outside the boss 510. In this implementation, the second sub-slide 116b penetrates the surface of the boss 510.

[0228] By providing the boss 510 and placing the third part 333 within it, on the one hand, when the electronic device has a need for thinning and cannot meet the installation requirements of the third locking part 430, the boss 510 provides installation space for the third locking part 430 and the third part 333. On the other hand, when the presence of other components in the first frame 110 would affect the sliding engagement of the locking assembly 330 with the third locking part 430 and the second locking mechanism along the first direction, the boss 510 shortens the engagement path between the locking assembly 330 and the third locking part 430 and the second locking mechanism, effectively simplifying the operation.

[0229] In this implementation, with the first frame 110 and the second frame 120 in a closed state, the boss 510 and the third locking part 430 are misaligned along the third direction. The projection of the boss 510 onto the second frame 120 along the second direction does not cover the third locking part 430.

[0230] Alternatively, in another implementation, with the first frame 110 and the second frame 120 in a closed state, the second part 332 can also be disposed inside the boss 510. In this implementation, along the second direction, the bottom surface of the boss 510 and the third locking part 430 are provided with a preset distance, wherein the preset distance is greater than or equal to zero.

[0231] Alternatively, in another implementation, the first frame 110 may not have any boss 510 structure. The locking unit 330 and the third locking part 430 are both provided on the first frame 110. The second sub-slide groove 116b penetrates the first surface 111, and the second part 332 can extend out of the first surface 111 of the first frame 110 through the second sub-slide groove 116b. In this implementation, along the second direction, the length of the second part 332 can be greater than the length of the first part 331, thereby facilitating better cooperation with the third limiting part 340.

[0232] In this way, the installation position of the third part 333 can be flexibly set according to the size of the electronic device and the mounting components in the frame, avoiding unnecessary installation space occupation and improving the space utilization rate of the electronic device.

[0233] It should be noted that the linkage process between the limiting locking integrated component 330 and the second locking mechanism provided in this application embodiment can refer to the linkage relationship between the components in the first locking mechanism in the aforementioned implementation method, which will not be repeated here.

[0234] Figure 19 This is a schematic diagram of a second rotating shaft mechanism that restricts a second frame, provided in an embodiment of this application. Figure 20 This is a schematic diagram of a second rotating shaft mechanism without limiting the second frame, provided in an embodiment of this application.

[0235] See Figure 19 and Figure 20 The second frame 120 includes a first limiting hole 121, which is formed by the second surface 122 of the second frame 120 being recessed inward along a first direction. The first limiting hole 121 is opposite to the first limiting part 310 in the closed state. The second surface 122 faces the first frame 110 in the closed state. The second rotating shaft mechanism 220 includes a second limiting hole 221, which communicates with the first limiting hole 121 and extends along a second direction. The second direction is perpendicular to the first direction and is the length direction of the electronic device.

[0236] The third limiting part 340 includes a limiting part 341 and a sliding part 342. The limiting part 341 is slidably disposed in the second limiting hole 221, and the sliding part 342 is slidably disposed in the first limiting hole 121. In the non-closed state, the first sub-part e1 of the limiting part 341 is located in the second limiting hole 221, and the second sub-part e2 slides into the first limiting hole 121 and abuts against the sliding part 342 to prevent the second rotating shaft mechanism 220 from driving the third frame 130 to rotate relative to the second frame 120. In the closed state, the limiting locking integral 330 is embedded in the first limiting hole 121, pushing the sliding part 342 to slide in the first limiting hole 121 to drive the limiting part 341 to slide in the second direction. The second sub-part e2 of the limiting part 341 slides into the second limiting hole 221 so that the second rotating shaft mechanism 220 can drive the third frame 130 to rotate toward the second frame 120.

[0237] The first limiting hole 121 includes a first sub-limiting hole 121a and a second sub-limiting hole 121b that are connected. The first sub-limiting hole 121a is formed by a recess inwardly recessed portion of the second surface 122 of the second frame 120 along a first direction. The second sub-limiting hole 121b is located at the end of the first sub-limiting hole 121a facing the second limiting hole 221 along a second direction, and the second sub-limiting hole 121b is connected to the second limiting hole 221. The sliding portion 342 includes a third sliding member 3421 and a fourth sliding member 3422 that are slidably engaged. In the non-closed state, the third sliding member 3421 and the fourth sliding member 3422 are... The first limiting member 3411 is abutted against each other along the first direction and located within the first sub-limiting hole 121a; the second sub-part e2 of the second limiting member 3411 slides into the second sub-limiting hole 121b and abuts against the fourth sliding member 3422; in the closed state, the limiting locking integral member 330 is embedded in the first sub-limiting hole 121a, pushing the third sliding member 3421 to slide along the first direction, thereby pushing the fourth sliding member 3422 to slide along the second direction into the second sub-limiting hole 121b, so as to drive the limiting part 341 to slide along the second direction, and the second sub-part e2 of the limiting part 341 slides into the second limiting hole 221.

[0238] Along the second direction, the sum of the widths of the first sub-restriction hole 121a and the second sub-restriction hole 121b is less than the sum of the widths of the third slider 3421 and the fourth slider 3422.

[0239] The end of the third slider 3421 facing the fourth slider 3422 includes a fifth inclined surface d1, which is inclined in the direction of the first direction toward the limiting part 341; the end of the fourth slider 3422 facing the third slider 3421 includes a sixth inclined surface d2, which is inclined in the direction of the first direction toward the limiting part 341; the fifth inclined surface d1 and the sixth inclined surface d2 are parallel, and the sliding engagement of the fifth inclined surface d1 and the sixth inclined surface d2 realizes the relative sliding of the third slider 3421 and the fourth slider 3422.

[0240] The limiting part 341 includes a second limiting member 3411 and a fourth elastic member 3412; in the non-closed state, the second sub-part e2 of the second limiting member 3411 slides into the second sub-limiting hole 121b and abuts against the second sliding member 3222; the first sub-part e1 of the second limiting member 3411 is disposed in the second limiting hole 221 through the fourth elastic member 3412, and the fourth elastic member 3412 is in an initial state; in the closed state, the second limiting member 3411 slides along the second direction and compresses the fourth elastic member 3412, and the fourth elastic member 3412 is in a compressed state.

[0241] The second limiting member 3411 also includes a protrusion e3, which is circumferentially disposed on the outer surface of the second limiting member 3411. A fourth elastic member 3412 is sleeved on the outer side of the second limiting member 3411. One end of the fourth elastic member 3412 is connected to the protrusion e3, and the other end abuts against the bottom surface of the second limiting hole 221. The inner surface of the second limiting hole 221 includes an annular groove 222, and the protrusion e3 is embedded in the annular groove 222. Along the second direction, the length of the annular groove 222 is greater than the length of the protrusion e3. The protrusion e3 is configured to be driven by the sliding of the second limiting member 3411 along the second direction and slides in the annular groove 222 along the second direction.

[0242] The protrusion e3 includes a first mating surface e31 and a second mating surface e32 that are opposite to each other along the second direction. The annular groove 222 includes a third end face c1 and a fourth end face c2 that are opposite to each other along the second direction. In the non-closed state, the first mating surface e31 of the protrusion e3 abuts against the third end face c1 of the annular groove 222, and the second mating surface e32 and the fourth end face c2 have a first distance. In the closed state, the second mating surface e32 of the protrusion e3 abuts against the fourth end face c2 of the annular groove 222, and the first mating surface e31 and the third end face c1 have a first distance.

[0243] It should be noted that the linkage process between the components of the limiting and locking integrated component 330 and the third limiting part 340 provided in this application embodiment can refer to the linkage relationship between the components of the first limiting part and the second limiting part in the aforementioned implementation method, which will not be repeated here.

[0244] Thus, the limiting and locking integrated component 330 provided in this application embodiment slides along the first direction under the action of external force, and cooperates with the third limiting part 340 to release the restriction on the second rotating shaft mechanism 210, and cooperates with the second locking mechanism to lock the first frame 110 and the second frame 120. The limiting rotation function and the locking function are integrated together and driven by the same limiting and locking integrated component 330, which effectively simplifies the structure, saves installation space, and is conducive to the miniaturization of electronic devices.

[0245] Figure 21 This is a schematic diagram of a first frame that automatically springs back to a preset angle, provided in an embodiment of this application.

[0246] In a specific implementation, see Figure 21 The first rotating shaft mechanism 210 is also provided with a damping element (not shown in the figure). After the first frame 110 and the second frame 120 are unlocked by the limiting locking integral component 330, the damping element on the first rotating shaft mechanism 210 can drive the first frame 110 to bounce at a preset angle away from the second frame 120, thereby forming a handle position for rotating the first frame 110.

[0247] It should be noted that, upon considering the specification and practicing the application disclosed herein, those skilled in the art will readily conceive of other embodiments of this application. This application is intended to cover any variations, uses, or adaptations of this application that follow the general principles of this application and include common knowledge or customary techniques in the art not disclosed herein.

[0248] It should be understood that this application is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The true scope is indicated by this application.
