The connection assembly 290 includes a positioning member 294 coupled to the hinge mechanism and a rotating member 295 rotatably coupled between the positioning member 294 and the cover member 291. The folding or unfolding of the hinge mechanism causes the cover 291 to rotate and slide relative to the central hinge joint 250 through the rotational engagement of the rotating member 295 with the positioning member 294. The foldable member 25 is folded or unfolded by a hinge mechanism, and the cover 291 is synchronously folded or unfolded by the connection member 290 according to the folding or unfolding of the hinge mechanism.

The utility model discloses a foldable device 24 of electronic equipment 100 is including the subassembly 25 that can bend and cover mechanism 29, and cover mechanism 29 is including covering in the covering 291 that can bend the subassembly 25 back and connecting in covering 291 and the coupling assembling 290 of the subassembly 25 that can bend, and coupling assembling 290 is including connecting in the setting element 294 of hinge mechanism and connecting in the rotation piece 295 between setting element 294 and covering 291 with rotating. The simultaneous folding and unfolding of the bendable elements 25 is achieved by a linkage mechanism 263, and the cover member 291 rotates and slides relative to the central hinge 250 by the rotational engagement of the rotating member 295 with the positioning member 294. Since the cover 291 covers the bendable elements 25, it can slide relative to the side hinges 255 as the bendable elements 25 bend or unfold. Therefore, when the foldable element 25 is unfolded and flat, the cover 291 covers the foldable element 25, so that dust or foreign materials can be prevented from entering the electronic device 100 from the foldable element 25, light leakage can be prevented, and the strength of the foldable device 24 can be protected.

Preferably, the positioning member 294 is fixedly connected to the middle hinge joint 250, and the rotating member 295 is rotatably connected to the positioning member 294 and the cover member 291, i.e., one end of the rotating member 295 is rotatably connected to the cover member 291 and the opposite end of the rotating member 295 is rotatably connected to the positioning member 294.

Specifically, as shown in fig. 13, the rotating member 295 and the cover member 291 are rotatably connected by a first rotating shaft L1, and the first rotating shaft L1 is a solid shaft; the rotating member 295 and the positioning member 294 are rotatably connected by a second rotating shaft L2, and the second rotating shaft L2 is a virtual shaft. The axial line of the first rotating shaft L1 is parallel to the axial line of the second rotating shaft L2 at intervals, and the axial line of the first rotating shaft L1 is parallel to the bending axis of the hinge mechanism. Preferably, the axis of the first rotating shaft L1 is farther from the bending axis of the hinge mechanism than the axis of the second rotating shaft L2; thus, during rotation of the side hinges 255 relative to the central hinge 250, the side hinges 255 can cause the corresponding cover 291 to rotate relative to the central hinge 250, and the cover 291 slides relative to the side hinges 255.

In this embodiment, the two opposite ends of the bendable elements 25 are respectively provided with a connecting assembly 26. Alternatively, the bendable assembly 25 may be other mechanisms that can meet the bending requirement, such as a flexible band, a spring, a soft rubber, a flexible steel plate, a rubber sheet, etc. Opposite sides of the support member 50 are fixedly attached to side hinges 255 on opposite sides of the bendable assembly 25. Each connecting assembly 26 includes a positioning member 261, a linkage mechanism 263, and two link members 265 rotatably disposed on opposite sides of the linkage mechanism 263. The linkage mechanism 263 is connected to the bendable assembly 25 through a positioning member 261, and specifically, two link members 265 are slidably inserted into the two side hinges 255, respectively. In this embodiment, the positioning member 261 comprises a watch chain assembly including a fixed member fixedly connected between the middle hinge joint 250 and the linkage mechanism 263 and a connecting member rotatably connected to opposite ends of the fixed member, each connecting member being slidably connected to the corresponding side hinge joint 255. Link 265 is connected between middle hinge 250 and side hinge 255 by linkage 263 and is slidable relative to side hinge 255 following bending or flattening of bendable assembly 25.

When the foldable device 22 is unfolded, the link 265 slides relative to the side hinge 255 to rotate the side hinge 255 away from each other relative to the middle hinge 250. When foldable device 22 is bent, link members 265 slide relative to side hinges 255 to bring about rotation of side hinges 255 toward each other relative to central hinge 250. Optionally, the foldable device 22 is provided with a first position-limiting part and a second position-limiting part, and when the foldable device 22 is in the fully unfolded state, the foldable device 22 is positioned at the first position-limiting part; when the foldable device 22 is in the fully folded state, the foldable device 22 is positioned at the second position-limiting portion. Specifically, when the foldable device 22 is unfolded, the side hinge 255 of the link member 265 moves toward the first position-limiting portion until abutting against or being adjacent to the first position-limiting portion, so as to limit the movement of the side hinge 255 relative to the link member 265. When the foldable device 22 is bent, the side hinge 255 of the link member 265 moves toward the second position-limiting portion until abutting against or adjacent to the second position-limiting portion, so as to limit the movement of the side hinge 255 relative to the link member 265.

As shown in fig. 4 and 5, two opposite ends of each side hinge 255 are respectively provided with a sliding slot 2550, and each sliding slot 2550 extends along a direction perpendicular to the bending axis of the bendable assembly 25 and penetrates through two opposite sides of the side hinge 255. One end of each link member 265 is rotatably connected to the corresponding linkage mechanism 263, and one end of each link member 265 far away from the linkage mechanism 263 is slidably inserted into the corresponding sliding slot 2550. When one of the side hinges 255 rotates relative to the middle hinge 250, the link member 265 inserted in the sliding slot 2550 of the one of the side hinges 255 slides relative to the one of the side hinges 255, and the link member 265 rotates relative to the middle hinge 250. Since the linkage mechanism 263 is disposed between the two link members 265 of each connecting assembly 26, when the rotation of the link member 265 inserted into one of the side hinges 255 relative to the middle hinge 250 drives the other link member 265 to rotate relative to the middle hinge 250, the rotation of the other link member 265 drives the other side hinge 255 to synchronously rotate relative to the middle hinge 250, thereby realizing the synchronous bending or flattening of the foldable device 22.

The middle of the back of each side hinge 255 is provided with two spaced slide rails 2554, and each slide rail 2554 extends perpendicular to the bending axis of the bendable assembly 25. In this embodiment, the slide rail 2554 is a slide extending perpendicular to the axis of the bendable elements 25. At least one retaining portion 2552 is disposed on a side of the back surface of each side hinge 255 away from the middle hinge 250, and the retaining portion 2552 is used for preventing the covering member 291 from being bent excessively to be separated from the side hinge 255. In this embodiment, two opposite ends of the back surface of each side hinge 255 away from the middle hinge 250 are respectively provided with a retaining portion 2552.

As shown in fig. 5, two opposite ends of the back surface of the middle hinge joint 250 are respectively provided with a receiving groove 2501, and the receiving groove 2501 is used for receiving the positioning element 294. Two opposite ends of the back surface of the middle hinge joint 250 are respectively provided with a clamping groove 2503, and the bottom surface of the clamping groove 2503 of the middle hinge joint 250 is provided with a positioning hole 2504 and a positioning column 2505. The back of the middle hinge joint 250 is also provided with positioning holes 2504 adjacent to the receiving slot 2501, and the two positioning holes 2504 are located at two opposite ends of the receiving slot 2501.

Referring to fig. 4-9, the shielding mechanism 29 is disposed at the inner side of the bending mechanism 25, and the shielding mechanism 29 is connected between the middle hinge joint 250 and the side hinge joints 255. In this embodiment, the shielding mechanism 29 comprises two covering members 291 covering the back of the bendable mechanism 25 and a connecting member 290 connected between the covering members 291 and the bendable mechanism 25. The connecting assembly 290 includes a positioning member 294 connected to the bendable mechanism 25 and a rotating member 295 rotatably connected between the positioning member 294 and each of the cover members 291, i.e., each of the cover members 291 is rotatably connected to the positioning member 294 by the rotating member 295. The folding or unfolding of the folding mechanism 25 drives the cover members 291 to slide relative to the corresponding side hinges 255 and rotate relative to the middle hinge 250, and the rotating member 295 rotates relative to the positioning member 294 and the cover members 291. In this embodiment, the positioning member 294 is fixedly connected to the receiving slot 2501 of the middle hinge joint 250. Because the linkage mechanism 263 is arranged between the connecting rod piece 265 and the middle hinge joint 250, when the side hinge joint 255 on one side rotates, the connecting rod piece 265 on the same side is driven to rotate, the connecting rod piece 265 drives the connecting rod piece 265 on the other side to rotate through the linkage mechanism 263, and then the side hinge joint 255 on the other side is driven to rotate, so that the two covering parts 291 rotate synchronously.

Each cover 291 includes a first cover 2911 covering the inner side of the bendable unit 25 and second covers 2913 provided at opposite ends of the first cover 2911, and the second covers 2913 slidably cover the bent ends of the bendable unit 25. The first covering portion 2911 is a strip-shaped shielding sheet, and the second covering portion 2913 is a shielding sheet protruding from the end edge of the first covering portion 2911. A protrusion 2914 is provided on a side of the second covering portion 2913 away from the first covering portion 2911, and the second covering portion 2913 and the corresponding protrusion 2914 form a guide groove 2915. Each side hinge 255 is slidably connected to the corresponding cover 291 by a sliding slot extending in a direction perpendicular to the axis of rotation between the side hinge 255 and the central hinge 250, the side hinge 255 rotating relative to the central hinge 250 to slide the sliding slot in the opposing sliding slot, such that the cover 291 slides relative to the side hinge 255 and the cover 291 also rotates relative to the central hinge 250.

The sliding distance of the cover 291 with respect to the side hinge 255 is greater than the sliding distance of the cover 291 with respect to the link 265 when the folding device 22 is bent. In this embodiment, the back of the covering member 291 is provided with a sliding groove 29160, and the sliding rail 2554 is provided on the side hinge joint 255; specifically, the back surface of each first covering portion 2911 is provided with two guide blocks 2916 and a connection block 2912 at intervals, each guide block 2916 is provided with a slide groove 29160 in a direction perpendicular to the rotation axis between the side hinge joint 255 and the middle hinge joint 250, and the slide rail 2554 is slidably inserted into the corresponding slide groove 29160. Each of the connection blocks 2912 is provided with a shaft hole in a direction parallel to a rotation axis between the side hinge 255 and the middle hinge 250, the rotation member 295 is rotatably connected to the connection block 2912 by a first rotation shaft L1 inserted through the shaft hole, and the connection block 2912 may be fixedly connected to the rear surface of the first covering portion 2911 by a fixing piece 29121, i.e., the connection block 2912 is protrudingly provided on the fixing piece 29121. In other embodiments, the fixing piece 29121 may be omitted, that is, the connection block 2912 may be directly and fixedly connected to the back surface of the first covering portion 2911. Each of the connection blocks 2912 and the corresponding guide 2916 may be connected to one body or may be separately provided. In this embodiment, two connection blocks 2912 on the back of one first covering portion 2911 are integrally connected to the corresponding guide block 2916, and two connection blocks 2912 on the back of the other first covering portion 2911 are spaced from the corresponding guide block 2916.

Referring to fig. 4-11, when the cover mechanism 29 is assembled to the middle hinge joint 250, the positioning element 294 is assembled to the middle hinge joint 250, specifically, the two positioning elements 294 are respectively accommodated in the two accommodating grooves 2501 of the middle hinge joint 250, so that the protruding piece 2944 of each positioning element 294 is clamped into the corresponding clamping groove 2503, the connecting hole 2945 of the protruding piece 2944 faces the positioning hole 2504, and the positioning column 2505 is clamped into the corresponding clamping hole 2946; the retainer 294 is fixedly attached to the middle hinge knuckle 250 by inserting the locking member into the attachment hole 2945 and locking it in the positioning hole 2504. Each of the rotating members 295 is rotatably coupled to the connecting block 2912, and specifically, the connecting block 2912 is inserted into the space 2952 between the two first rotating portions 2951 of the corresponding rotating member 295 such that the shaft hole 2953 of the first rotating portion 2951 is aligned with the shaft hole 29120 of the connecting block 2912, and the first rotating shaft L1 is inserted into the shaft holes 2953, 29120, at which time the rotating member 295 is rotatably coupled to the connecting block 2912 along the first rotating shaft L1. Two cover members 291 are spaced apart and cover the back of the foldable mechanism 25 such that each of the rotating members 295 is rotatably inserted into the space between the corresponding two guide rails 2941 and each of the guide rails 2941 is rotatably received in the corresponding guide groove 2956. At the same time, the two slide rails 2554 of each side hinge joint 255 are slidably fitted to the slide grooves 29160 of the two guide blocks 2916 of the corresponding cover 291. The second covering portion 2913 of each covering member 291 slidably covers the two opposite ends of the corresponding side hinge joint 255, i.e., the two opposite ends of the side hinge joint 255 are slidably received in the guiding grooves 2915 of the two opposite ends of the covering member 291. As the folding device 22 is bent, the cover 291 slides against the side hinge 255. Alternatively, as the bendable mechanism 25 bends, the cover 291 slides relative to the side hinge 255 away from the middle hinge 250, while the link 265 slides relative to the side hinge 255. Alternatively, when the folding device 22 is in the unfolded state, the two covers 291 are flattened to cover the back of the foldable mechanism 25, and the second cover 2913 covers the end of the foldable mechanism 25 to prevent the exposure of the internal components and to prevent impurities such as dust from entering the folding device 22 from the back and the end.

As shown in fig. 13 and 16, the first rotating portion 2951 of each rotating member 295 rotates with the corresponding cover 291 along the first rotating axis L1, and the second rotating portion 2955 and the positioning member 294 rotate with each other along the guiding groove 2956, that is, the second rotating portion 2955 and the positioning member 294 rotate along the second rotating axis L2. The axial line interval of the first rotating shaft L1 is parallel to the axial line of the second rotating shaft L2, and the axial line interval of the first rotating shaft L1 is parallel to the rotating axis between the side hinge joint 255 and the middle hinge joint 250. Preferably, the axis of the first rotating shaft L1 is farther from the central hinge joint 250 than the axis of the second rotating shaft L2.

In the embodiment shown in fig. 3, the support member 50 is a flexible support member, and the support member 50 covers the front surfaces of the two side hinges 255 and the front surface of the middle hinge 250. Specifically, opposite sides of the back surface of the support 50 are fixedly connected to the front surfaces of the two side hinges 255, respectively; the support member 50 bends or flattens with the folding device 22. Specifically, the supporting element 50 includes a bendable region 522 and two connecting regions 524 disposed at opposite sides of the bendable region 522, and the two connecting regions 524 are respectively fixedly connected to the front surfaces of the two lateral hinges 255. Alternatively, the length of the supporting member 50 can be increased, and one of the connection areas 524 of the supporting member 50 is connected to the corresponding side hinge joint 255, and the other connection area 524 is connected to the second frame 23 and the corresponding side hinge joint 255. Optionally, the bendable region 256 of the support member 50 is slidably connected to the central hinge joint 250, and the bendable region 522 slides relative to the central hinge joint 250 when the folding device 22 is bent. Optionally, when the folding device 22 is bent, both side hinges 255 slide relative to the center hinge 250 to reduce the tensile force experienced by the support 50, leaving the support 50 at a constant or substantially constant length.

Referring to fig. 4-5 and 15-17, when the folding device 22 is bent, the one side hinge 255 is rotated toward the other side hinge 255, and the two link members 265 slide in the slide slots 2550 of the one side hinge 255, so that the two link members 265 rotate relative to the middle hinge 250. Since the two link members 265 of each connecting assembly 26 are connected by the linkage mechanism 263, when the link member 265 connected between the one side hinge 255 and the linkage mechanism 263 rotates, the link member 265 arranged between the other side hinge 255 and the linkage mechanism 263 rotates relative to the middle hinge 250, and the link member 265 slides in the sliding slot 2550 of the other side hinge 255 to drive the other side hinge 255 to synchronously rotate towards the one side hinge 255; the two link members 265 of each connecting assembly 26 are brought together to effect the linked bending of the folding device 22.

In the bending process, each covering member 291 slides in the corresponding sliding groove 29160 through the sliding rail 2554 to drive the rotating member 295 to rotate relative to the corresponding connecting member 294, that is, the guide rail 2941 rotates in the corresponding guide groove 2956, so that the covering member 291 slides relative to the corresponding side hinge joint 255 until one side of the covering member 291, which is far away from the middle hinge joint 250, abuts against the anti-disengaging portion 2552 of the corresponding side hinge joint 255, the two covering members 291 rotate mutually to be closed, and the covering member 291 is always attached to the back surface of the folding device 22. The cover 291 can be positioned and prevented from swinging due to the cooperation of the guide rail and the guide groove. When the folding device 22 completes folding, the two covering pieces 291 abut against the corresponding retaining portions 2552, respectively, and further folding of the covering pieces 291 is prevented.

In another usage, the two side hinges 255 may be rotated together in opposite directions, and since the two link members 265 of each connecting assembly 26 are connected by the linking mechanism 263, the two side hinges 255 drive the link members 265 of each connecting assembly 26 to rotate together, so that the two link members 265 approach each other, and the two side hinges 255 approach each other simultaneously to bend the folding device 22.

When the folding device 22 is unfolded from the bent state, the one side hinge 255 is rotated away from the other side hinge 255, the two link members 265 slide in the slide slots 2550 of the side hinges 255, so that the two link members 265 rotate relative to the middle hinge 250 and the link members 265 slide in the slide slots 2550. Since the two link members 265 of each connecting assembly 26 are connected by the linkage mechanism 263, when the link member 265 connected between the one side hinge 255 and the linkage mechanism 263 rotates, the link member 265 arranged between the other side hinge 255 and the linkage mechanism 263 can be driven to rotate relative to the middle hinge 250, and the link member 265 slides in the sliding groove 2550 of the other side hinge 255 to drive the other side hinge 255 to synchronously rotate away from the one side hinge 255; the two link members 265 of each connecting assembly 26 are moved away from each other to effect the linked flattening of the folding device 22.

During the flattening process, each cover 291 slides in the corresponding sliding slot 29160 through the sliding rail 2554 to drive the rotating member 295 to rotate relative to the corresponding connecting member 294, that is, the guide rail 2941 rotates in the corresponding guide slot 2956, so that the two cover 291 rotate and flatten with each other, the cover 291 is always attached to the back of the folding device 22, and the two opposite side surfaces of the two cover 291 are attached to each other to prevent impurities such as dust from entering the folding device 22 from the back of the electronic device 100. The cover 291 can be positioned and prevented from swinging due to the cooperation of the guide rail and the guide groove.

In other usage, the two side hinges 255 may rotate together in the direction away from each other, and since the two link members 265 of each connecting assembly 26 are connected by the linkage mechanism 263, the two side hinges 255 drive the link member 265 of each connecting assembly 26 to rotate together, so that the two link members 265 of each connecting assembly 26 are away from each other, and thus the two side hinges 255 are synchronously away from each other to flatten the folding device 22.

The link member 265 of the transmission mechanism 26 slides with respect to the side hinge 255 while the side hinge 255 moves with respect to the middle hinge 250. Specifically, as the side hinge 255 rotates and slides relative to the middle hinge 250, the link member 265 connected between the side hinge 255 and the middle hinge 250 slides relative to the side hinge 255.

Referring to fig. 1 to 3 and 12 to 14, the folding device 22 is disposed between the first frame 21 and the second frame 23, such that the two side hinges 255 of the folding device 22 are connected to the first frame 21 and the second frame 23 at the sides away from the middle hinge 250. The front surface of the support member 50 of the folding device 22 is made coplanar with the front surface of the first frame 21 and the front surface of the second frame 23. The back surfaces of the two non-bent portions 33 of the flexible screen 30 are fixed to the front surfaces of the first frame body 21 and the corresponding side hinges 255 and the front surfaces of the second frame body 23 and the corresponding side hinges 255. The back of the bendable part 31 of the flexible screen 30 is slidably attached to the front of the supporting member 50, and the two can be adhered by elastic glue. The back of the support member 50 is slidably engaged with the central hinge joint 250, and the two are bonded together by an elastic adhesive.

Referring to fig. 12 to 18, when the electronic device 100 is bent, a bending force is applied to at least one of the first frame 21 and the second frame 23 of the electronic device 100, so that the side hinge 255 connected to the first frame 21 and the side hinge 255 connected to the second frame 23 rotate in directions adjacent to each other, the two connecting assemblies 26 are used to bend the folding device 22, and the bendable region 31 of the flexible element 30 is bent synchronously with the bending of the supporting element 50. Specifically, if a bending force is applied to the first frame body 21, the first frame body 21 drives the side hinge joint 255 to rotate relative to the middle hinge joint 250 toward the side away from the flexible member 30; the side hinge 255 drives the two link members 265 corresponding to the two connecting assemblies 26 to rotate, and the two link members 265 slide in the two slide slots 2550 of the side hinge 255 respectively. Since the two link members 265 of each connecting assembly 26 are connected by the linkage mechanism 263, when the link member 265 connected between the one side hinge 255 and the linkage mechanism 263 rotates, the link member 265 arranged between the other side hinge 255 and the linkage mechanism 263 can be driven to rotate relative to the middle hinge 250, and the link member 265 slides in the sliding groove 2550 of the other side hinge 255 to drive the other side hinge 255 to synchronously rotate towards the one side hinge 255; the two link members 265 of each connecting assembly 26 are moved toward each other to realize the linked bending of the folding device 22, the bendable region 31 of the flexible member 30 bends along with the folding device 22, and the first frame 21 and the second frame 23 move toward each other until the back surfaces of the first frame 21 and the second frame 23 are attached to each other.

During the bending process of the electronic device 100, the two side hinges 255 respectively rotate with respect to the middle hinge 250. Specifically, the two covers 291 of the shielding mechanism 29 rotate relative to the middle hinge joint 250 along with the bending of the folding device 22, and the covers 291 slide relative to the side hinge joints 255 until the covers 291 abut against the corresponding anti-falling portions 2552, preventing the covers 291 from being folded further, and the covers 291 cover the back of the foldable mechanism 25 all the time, so as to prevent impurities such as dust from entering the folding device 22 from the back of the electronic device 100. When the electronic device 100 is folded, the two covering parts 291 abut against the corresponding anti-falling parts 2552, so as to prevent the covering parts 291 from being further folded and damage the flexible part 30.

In another bending manner of the electronic device 100, a bending force may be simultaneously applied to the first frame 21 and the second frame 23, and the first frame 21 and the second frame 23 respectively drive the corresponding side hinge 255 to rotate relative to the side away from the flexible member 30, and the electronic device 100 is bent by the folding device 22.

When the electronic device 100 needs to be unfolded, the first frame 21 or the second frame 23 is pulled outward, and the side hinge 255 connected to the first frame 21 and the side hinge 255 connected to the second frame 23 are rotated in a direction away from each other. Specifically, a force that pulls at least one of the first housing 21 and the second housing 23 of the electronic apparatus 100 outward is applied, and the side hinge 255 connected to the first housing 21 and the side hinge 255 connected to the second housing 23 are rotated in directions away from each other. If a force is applied to the first frame body 21 to pull it outward, the first frame body 21 drives the link members 265 on the side hinges 255 to rotate toward one side of the flexible member 30 relative to the middle hinge, and the link members 265 slide in the slide grooves 2550. Since the two link members 265 of each connecting assembly 26 are connected by the linkage mechanism 263, when the link member 265 connected between the one side hinge 255 and the linkage mechanism 263 rotates, the link member 265 arranged between the other side hinge 255 and the linkage mechanism 263 can be driven to rotate relative to the middle hinge 250, and the link member 265 slides in the sliding groove 2550 of the other side hinge 255 to drive the other side hinge 255 to synchronously rotate away from the one side hinge 255; the first frame body 21 and the second frame body 23 are away from each other to realize the linked flattening of the electronic device 100, and the bendable region 31 of the flexible member 30 is flattened along with the folding device 22.

In other bending modes of the electronic device 100, a force for pulling the first frame 21 and the second frame 23 outward may be applied simultaneously, and the first frame 21 and the second frame 23 respectively drive the corresponding side hinges to rotate along the corresponding rotation shafts 281 toward one side of the flexible member 30, so as to flatten the electronic device 100.

The above is an implementation manner of the embodiments of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principles of the embodiments of the present invention, and these improvements and decorations are also considered as the protection scope of the present invention.
