Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.

[0054] In addition, the following descriptions of the various embodiments refer to the accompanying drawings to illustrate specific embodiments that may be implemented in the present application. Directional terms mentioned in this application, such as "upper," "lower," "front," "back," "left," "right," "inner," "outer," and "side," are only used with reference to the directions in the accompanying drawings. Therefore, the directional terms used are intended to better and more clearly illustrate and understand the present application, and are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be understood as limitations on the present application.

[0055] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connected," and "disposed on" should be understood broadly. For example, they may refer to fixed connection, detachable connection, or integral connection; they may refer to mechanical connection; they may refer to direct connection, indirect connection via an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0056] Please also refer to Figures 1 to 7In one embodiment of the present invention, an electronic device 100 includes a folding shell 20 and a flexible screen 30 provided on the folding shell 20. The folding shell 20 includes two frames 21, a folding device 40 and a magnetic attraction mechanism 60. The opposite sides of the folding device 40 are respectively connected between the two adjacent frames 21; the magnetic attraction mechanism 60 includes a first magnetic member 61, a second magnetic member 65 and a control member 67. The first magnetic member 61 is provided on one of the frames 21, and the second magnetic member 65 is provided on the other frame 21; the flexible screen 30 is provided on the front of the two frames 21 and the front of the folding device 40. The flexible screen 30 includes a bendable area 31 and two non-bending areas 33 provided on the folding device 40. The two non-bending areas 33 are respectively connected to the opposite sides of the bendable area 31, and the two non-bending areas 33 are respectively connected to the front of the two frames 21. The folding device 40 is used to support the bendable area 31 of the flexible screen 30. The flexible screen 30 can be bent or flattened as the folding device 40 is bent or flattened. The bendable area 31 can be bent into a U-shape, a teardrop shape, or other shapes. When the folding shell 20 is in a folded state, the first magnetic member 61 and the second magnetic member 65 are directly opposite each other, and the control member 67 is used to control the mutual magnetic attraction or mutual repulsion between the first magnetic member 61 and the second magnetic member 65. When the control member 67 controls the mutual magnetic attraction between the first magnetic member 61 and the second magnetic member 65, the two frames 21 of the folding shell 20 remain in a folded state; when the control member 67 controls the mutual repulsion between the first magnetic member 61 and the second magnetic member 65, the two frames 21 of the folding shell 20 rotate away from each other and automatically unfold.

[0057] It should be noted that: the front side refers to the side facing the same direction as the light-emitting surface of the flexible screen 30, and the back side refers to the side facing away from the light-emitting surface of the flexible screen 30. The electronic device 100 is, for example, but not limited to, a mobile phone, a tablet computer, a display, a liquid crystal panel, an OLED panel, a television, a smart watch, a VR head-mounted display, a car display, or any other product and component with a display function. The "connection" in the description of the embodiment of the present invention includes both direct connection and indirect connection. For example, the connection between A and B includes A and B being directly connected or connected through a third element C or more other elements. The connection also includes two situations: integrated connection and non-integrated connection. The integrated connection means that A and B are formed and connected as one body, and the non-integrated connection means that A and B are formed and connected as a non-integrated body.

In this embodiment, the first magnetic member 61 includes five arranged first magnets 610, and the polar directions of the front faces of every two adjacent first magnets 610 are opposite.

In other words, the five second magnets 650 are arranged in the order of position 1 to position 5, with the front polarities of the second magnet 650 in position 1, position 3, and position 5 all facing south poles, and the front polarities of the second magnet 650 in position 2 and position 4 all facing north poles. The arrangement direction of the plurality of first magnets 610 is parallel to the arrangement direction of the plurality of second magnets 650.

[0060] When the plurality of first magnets 610 are positioned at the first position relative to the plurality of second magnets 650, the first magnet 610 at the first position is opposite to the second magnet 650 at the first position and has opposite polarity, the first magnet 610 at the second position is opposite to the second magnet 650 at the second position and has opposite polarity, the first magnet 610 at the third position is opposite to the second magnet 650 at the third position and has opposite polarity, the first magnet 610 at the fourth position is opposite to the second magnet 650 at the fourth position and has opposite polarity, and the first magnet 610 at the fifth position is opposite to the second magnet 650 at the fifth position and has opposite polarity. When the plurality of first magnets 610 are positioned at the second position relative to the plurality of second magnets 650, the first magnet 610 at the first position and the second magnet 650 at the first position are offset from each other, so that the first magnet 610 at the second position and the second magnet 650 at the first position are opposite and have the same polarity, the first magnet 610 at the third position and the second magnet 650 at the second position are opposite and have the same polarity, the first magnet 610 at the fourth position and the second magnet 650 at the third position are opposite and have the same polarity, and the first magnet 610 at the fifth position and the second magnet 650 at the fourth position are opposite and have the same polarity; or the first magnet 610 at the first position and the second magnet 650 at the second position are opposite and have the same polarity, the first magnet 610 at the second position and the second magnet 650 at the third position are opposite and have the same polarity, the first magnet 610 at the third position and the second magnet 650 at the fourth position are opposite and have the same polarity, and the first magnet 610 at the fourth position and the second magnet 650 at the fifth position are opposite and have the same polarity.

[0061] Optionally, the plurality of first magnets 610 can slide relative to the plurality of second magnets 650 in a first direction, so that the first magnets 610 at positions 1 to 5 are respectively aligned with or offset from the second magnets 650 at positions 1 to 5; or the plurality of second magnets 650 can slide relative to the plurality of first magnets 610 in the first direction, so that the first magnets 610 at positions 1 to 5 are respectively aligned with or offset from the second magnets 650 at positions 1 to 5. The plurality of first magnets 610 can slide relative to the plurality of second magnets 650 in a second direction, so that the first magnets 610 at positions 1 to 5 are respectively aligned with or offset from the second magnets 650 at positions 1 to 5; or the plurality of second magnets 650 can slide relative to the plurality of first magnets 610 in the second direction, so that the first magnets 610 at positions 1 to 5 are respectively aligned with or offset from the second magnets 650 at positions 1 to 5. The first direction and the second direction are parallel to the arrangement direction of the plurality of first magnets 610 , and the first direction is opposite to the second direction.

[0062] In other embodiments, the first magnetic member 61 includes at least two first magnets 610, and the front magnetic poles of the at least two first magnets 610 are opposite. The second magnetic member 65 includes at least two second magnets 650, and the front magnetic poles of the two second magnets 650 are opposite. When the two frames 21 are in a folded state, the two first magnets 610 are magnetically attracted to the two second magnets 650 respectively, and the control member 67 can control the movement of the two first magnets 610 relative to the two second magnets 650, so that the polar directions of the first magnets 610 and the second magnets 650 are the same and repel each other, so that the two frames 21 of the electronic device 100 are automatically unfolded. In other embodiments, the first magnetic component 61 may include more than three first magnets 610 arranged in the same direction, and the magnetic poles of the front faces of each two adjacent first magnets 610 are opposite; the second magnetic component 65 may include more than three second magnets 650 arranged in the same direction, and the magnetic poles of the front faces of each two adjacent second magnets 650 are opposite; when the two frames 21 are in a folded state, the three or more first magnets 610 are respectively opposite to the magnetic poles of the three or more second magnets 650 and are attracted to each other. When the control component 67 drives the first magnetic component 61 and the second magnetic component 65 to move relative to each other, the magnetic poles between the first magnet 610 and the corresponding second magnet 650 can be made the same and repel each other, so that the two frames 21 of the electronic device 100 are automatically unfolded.

[0063] like Figure 1-Figure 3As shown, one frame 21 is provided with a first receiving groove 210, and the other frame 21 is provided with a second receiving groove 212. A plurality of first magnets 610 are slidably received in the first receiving groove 210, and a plurality of second magnets 650 are received in the second receiving groove 212. A control member 67 drives the plurality of first magnets 610 to slide in the first receiving groove 210 so that the magnetic poles of the first magnets 610 and the second magnets 650 are the same or opposite. The frame 21 includes a first front face 211, a back face 213, two opposing side faces 214, and two opposing end faces 215. The first receiving groove 210 is located at the end of one of the frame 21 away from the folding device 40, and the second receiving groove 212 is located at the end of the other frame 21 away from the folding device 40. Specifically, a first receiving groove 210 is provided at one end of the first front face 211 of one frame 21 away from the folding device 40, and a second receiving groove 212 is provided at one end of the first front face 211 of the other frame 21 away from the folding device 40. The length direction of the first receiving groove 210 is parallel to the arrangement direction of the plurality of first magnets 610, and the length direction of the second receiving groove 212 is parallel to the arrangement direction of the plurality of second magnets 650. When the two frames 21 are folded together, the first receiving groove 210 and the second receiving groove 212 are opposite each other, and the first magnetic member 61 and the second magnetic member 65 are opposite each other. In this embodiment, the length of the first receiving groove 210 is greater than the arrangement length of the plurality of first magnets 610. The control member 67 can drive the plurality of first magnets 610 to slide along the length direction of the first receiving groove 210, and the plurality of second magnets 650 are positioned in the second receiving groove 212, so that the first magnetic member 61 moves relative to the second magnetic member 65, thereby achieving the mutual displacement or resetting of the plurality of first magnets 610 and the plurality of second magnets 650.

[0064] In other embodiments, the length of the second receiving groove 212 is greater than the arrangement length of the multiple second magnets 650, and the control member 67 can drive the multiple second magnets 650 to slide along the length direction of the second receiving groove 212. The multiple first magnets 610 are positioned in the first receiving groove 210 to enable the second magnetic member 65 to move relative to the first magnetic member 61, thereby achieving the mutual dislocation or resetting of the multiple second magnets 650 and the multiple first magnets 610.

[0065] In this embodiment, the first receiving groove 210 is close to one of the side surfaces 214, and the length direction of the first receiving groove 210 is perpendicular to the folding axis of the folding device 40.

The elastic member 475 provides elastic force to push the supporting member 473 and the positioning member 476, so that the supporting member 473 and the connecting rod member 462 abut against each other, and the positioning member 476 and the friction assembly 477 abut against each other; the supporting member 473 includes a second cam 4730 slidably mounted on the rotating shaft 461, and the second cam 4730 is rotatably engaged with the first cam 460 of the corresponding connecting rod member 462. When the first cam 460 rotates relative to the second cam 4730, the second cam 4730 slidably pushes against the abutting curved surface 4601, causing the abutting member 473 to slide axially along the rotation axis 461, thereby squeezing the elastic member 475. Optionally, the second cam 4730 can automatically slide from the second abutting section 4604 to the hovering section 4603 under the pushing force of the elastic member 475, thereby driving the connecting rod 462 to rotate relative to the base 44 and flatten to a hovering state.

[0087] During the folding process of the folding device 40, the two connecting rods 462 rotate around the axes of the corresponding rotating shafts 461 relative to the base 44 and approach each other. The second cam 4730 slides from the first abutting section 4602 to the second abutting section 4604 via the hovering section 4603 on the corresponding abutting curved surface 4601 to push the supporting member 473 to slide along the axial direction of the rotating shaft 461 toward the side away from the connecting rod 462. The elastic member 475 is compressed, and the two rotating mechanisms 45 rotate synchronously relative to the base 44 and approach each other, so that the two side support members 423 of the support assembly 42 are folded relative to the middle support member 421. During the flattening process of the folding device 40, the second cam 4730 can automatically slide from the second abutting section 4604 to the hovering section 4603 under the action of the resisting force of the elastic member 475, so as to drive the connecting rod 462 to rotate relative to the base 44, so that the folding device 40 is automatically unfolded from the folded state to the hovering state; specifically, the elastic member 475 elastically resists the abutting member 473 to push the abutting member 473 to slide along the axial direction of the rotating shaft 461 toward one side of the connecting rod 462, so that the second cam 4730 automatically slides from the second abutting section 4604 to the hovering section 4603 on the corresponding abutting curved surface 4601, and the two connecting rods 462 automatically rotate around the axis of the corresponding rotating shaft 461 relative to the base 44 and move away from each other. The elastic member 475 partially resets, and the two rotating mechanisms 45 synchronously rotate relative to the base 44 and away from each other, causing the two side support members 423 of the support assembly 42 to unfold relative to the central support member 421, and the support assembly 42 of the folding device 40 to automatically unfold from the folded state to the hovering state. The user continues to unfold the folding device 40, causing the second cam 4730 to slide from the hovering section 4603 to the first abutting section 4602, thereby driving the connecting rod 462 to rotate relative to the base 44, causing the folding device 40 to unfold from the hovering state to the flattened state until the second cam 4730 abuts the corresponding first abutting section 4602. The elastic member 475 maintains abutment against the abutting member 473, keeping the folding device 40 in the flattened state. The elastic member 475 includes a spring sleeved around each rotating shaft 461 and is located between the positioning member 476 and the abutting member 473.

[0088] The second cam 4730 includes at least one second protrusion 4731. The second protrusion 4731 has a sliding surface 4733 facing the first cam 460. The sliding surface 4733 can slidably abut against the abutting curved surface 4601. In this embodiment, the second cam 4730 includes two second protrusions 4731, which are arranged circumferentially around the rotation shaft 461. Each second protrusion 4731 has a sliding surface 4733 facing the corresponding first cam 460. The two sliding surfaces 4733 of the second cam 4730 respectively slidably abut against the two abutting curved surfaces 4601 of the corresponding first cam 460. Optionally, the two second protrusions 4731 of the second cam 4730 are evenly spaced apart around the circumference of the rotation shaft 461, with a second recess 4735 formed between the two second protrusions 4731. During the process of the second cam 4730 sliding from the second abutting section 4604 of the corresponding abutting curved surface 4601 to the hovering section 4603, there is an unfolding force between the second cam 4730 and the abutting curved surface 4601 that drives the connecting rod 462 to rotate relative to the base 44 and unfold, so that the folding device 40 automatically unfolds from the folded state to the hovering state.

[0089] Optionally, both the first abutting section 4602 and the second abutting section 4604 are closer to the abutting member 473 than the hovering section 4603. Specifically, a first length L1 of the first abutting section 4602 extending axially along the rotation axis 461 and a second length L2 of the second abutting section 4604 extending axially along the rotation axis 461 are both greater than a third length L3 of the hovering section 4603 extending axially along the rotation axis 461. The first length L1 may be equal to or different from the second length L2. The axial length of the first protrusion 4605 extending axially along the rotation axis 461 gradually decreases from the first abutting section 4602 to the hovering section 4603, and the axial length of the first protrusion 4605 extending axially along the rotation axis 461 gradually decreases from the second abutting section 4604 to the hovering section 4603. When the second protrusion 4731 automatically slides from the second abutting section 4604 to the hovering section 4603 on the corresponding abutting curved surface 4601, the folding device 40 automatically unfolds from the folded state to the hovering state; there is an unfolding force between the second cam 4730 and the abutting curved surface 4601 that drives the connecting rod 462 to rotate relative to the base 44 until the second cam 4730 is positioned at the hovering section 4603. In other embodiments, the number of second protrusions 4731 on the second cam 4730 corresponds to the first protrusions 4605 on the corresponding first cam 460, and the first cam 460 includes more than three first protrusions 4605, which are evenly spaced along the circumference of the rotating shaft 461, and a first recessed portion 4608 is formed between each adjacent two first protrusions 4605; the second cam 4730 includes more than three second protrusions 4731, which are evenly spaced along the circumference, and a second recessed portion 4735 is formed between each adjacent two second protrusions 4731.

The supporting member 473 includes two second cams 4730 located at opposite ends thereof. The two second cams 4730 are respectively sleeved on the two rotating shafts 461. One of the second cams 4730 slidably abuts one of the abutting curved surfaces 4601, and the other second cam 4730 slidably abuts the other abutting curved surface 4601. The supporting member 473 also includes two second sleeves 4732 located at opposite ends thereof. The axes of the two second sleeves 4732 are spaced apart and parallel. The two second sleeves 4732 are respectively slidably sleeved on the two rotating shafts 461. The rotating shafts 461 are rotatable relative to the supporting member 473, and the supporting member 473 is slidable along the axial direction of the rotating shafts 461. Two second cams 4730 are disposed on the same side of the two second sleeves 4732, respectively. Each second cam 4730 is coaxial with the corresponding second sleeve 4732. One second cam 4730 slidably abuts one of the abutting curved surfaces 4601, while the other second cam 4730 slidably abuts the other abutting curved surface 4601. The second cams 4730 include two second protrusions 4731, which are arranged circumferentially around the corresponding second sleeve 4732. Each second protrusion 4731 has a sliding surface 4733 on one end facing the first cam 460. Preferably, the two second protrusions 4731 of the second cams 4730 are evenly spaced apart along the circumference of the corresponding second sleeve 4732. The supporting member 473 also includes a connecting portion 4734 connected between the two second sleeves 4732, and the connecting portion 4734 is provided with two second axial holes 4736, and the axis of the second axial holes 4736 is parallel to the axis of the second cam 4730; the opposite ends of the rotating shaft 4644 of the linkage gear 4642 are respectively passed through the first axial hole 4654 and the second axial hole 4736.

[0091] The positioning member 476 has second guide holes 4765 at opposite ends. The shafts 4610 of the two rotating shafts 461 are respectively inserted into the second guide holes 4765. The rotating shafts 461 can rotate within the second guide holes 4765, while the positioning member 476 can only slide axially along the two rotating shafts 461. Specifically, the positioning member 476 comprises a rectangular guide plate 4761 and an extension 4763 located in the middle of one side of the guide plate 4761. The second guide holes 4765 are respectively provided at opposite ends of the guide plate 4761, and the opposite end surfaces of the guide plate 4761 are arc-shaped. The extension 4763 is located between the two second guide holes 4765, and the end surface of the extension 4763 facing away from the guide plate 4761 is provided with two avoidance holes 4767. Preferably, a first anti-slip portion 4768 is provided around the second guide sliding hole 4765 on the side of the guide sliding piece 4761 facing away from the extension portion 4763. Specifically, the first anti-slip portion 4768 can be but is not limited to a protrusion, a hole or a rough surface provided on the guide sliding piece 4761.

[0092] The friction assembly 477 includes a first friction member 4770, a washer 478, a second friction member 4775, and a C-shaped buckle 4779. These three components are sequentially connected to the rotating shaft 461. The first friction member 4770 is located between the washer 478 and the positioning member 476, while the second friction member 4775 is located between the washer 478 and the C-shaped buckle 4779. The first friction member 4770 abuts against the positioning member 476 and the washer 478, while the second friction member 4775 abuts against the washer 478. When the rotating shaft 461 rotates relative to the base 44, the first and second friction members 4770 and 4775 rotate with the rotating shaft 461. Frictional resistance exists between the first friction member 4770 and the positioning member 476 and the washer 478, and between the second friction member 4775 and the washer 478.

[0093] Specifically, the first friction member 4770 is a circular friction plate with a first positioning hole 4772 defined in its center. The first friction member 4770 is fixedly connected to the rotating shaft 461 via the first positioning hole 4772. Second anti-slip portions 4774 are provided on opposite sides of the first friction member 4770. In some embodiments, the first anti-slip portion 4768 on the side of the first friction member 4770 facing the positioning member 476 may be omitted, leaving only the second anti-slip portion 4774 on the side of the first friction member 4770 facing the positioning member 476. Alternatively, the second anti-slip portion 4774 on the side of the first friction member 4770 facing the positioning member 476 may be omitted, leaving only the first anti-slip portion 4768 on the positioning member 476. The gasket 478 is rectangular, with arc-shaped surfaces at its opposite ends. A third anti-slip portion 4784 is provided on opposite sides of the gasket 478. In this embodiment, through-holes 4782 are provided at opposite ends of the gasket 478, and a third anti-slip portion 4784 is provided on opposite sides of the gasket 478 around each through-hole 4782.

[0096] Please also refer to Figures 14-21 and Figure 24-25When assembling the folding aid assembly 41, the ends of the two rotating shafts 461 away from the connecting cap 4612 are respectively inserted into the two first guide sliding holes 4652 of the fixing member 465 until the fixing member 465 stops at the connecting cap 4612; the two linkage gears 4642 are respectively engaged with the two driving gears 4621, and the ends of the two rotating shafts 461 with the card slots 4616 are respectively inserted into the sleeve holes 4624 of the two first sleeves 4622 from the end away from the first cam 460, and the two rotating shafts 4644 of the gear set 464 are respectively inserted into the two first shaft holes 4654 of the fixing member 465, and the positioning parts 4656 are accommodated in the corresponding notches of the first sleeves 4622; at this time, each positioning part 4656 is located between the corresponding first limiting surface 4626 and the second limiting surface 4627. The two second sleeves 4732 of the supporting member 473 are respectively sleeved on the shaft bodies 4610 of the two rotating shafts 461. The first cam 460 and the second cam 4730 on the same rotating shaft 461 are coaxial. The two second cams 4730 of the supporting member 473 are respectively rotatably engaged with the two first cams 460. The two rotating shafts 4644 are respectively inserted into the two second shaft holes 4736 of the supporting member 473 until the ends of the rotating shafts 4644 are exposed on the side of the supporting member 473 facing away from the fixing member 465. The two elastic members 475 are respectively sleeved on the two shaft bodies 4610. The ends of the two rotating shafts 461 with the card slots 4616 are respectively inserted into the two second guide slide holes 4765 of the positioning member 476. , and the two rotating shafts 4644 are respectively inserted into the two avoidance holes 4767 of the positioning member 476, so that the elastic member 475 is clamped between the supporting member 473 and the positioning member 476; two of the first friction members 4770 are respectively sleeved on the two rotating shafts 461, and the gasket 478 is sleeved on the two rotating shafts 461, and then the two second friction members 4775 are respectively sleeved on the two rotating shafts 461. At this time, the gasket 478 is located between the first friction member 4770 and the second friction member 4775, and the slot 4616 of each rotating shaft 461 exposes the side of the corresponding second friction member 4775 away from the positioning member 476; then the two C-shaped buckles 4779 are respectively clamped on the slots 4616 of the two rotating shafts 461. At this time, the two C-shaped clips 4779 respectively press against the sides of the two second friction members 4775 facing away from the positioning member 476, the elastic member 475 is in a squeezed state, the opposite ends of the elastic member 475 respectively press against the supporting member 473 and the positioning member 476, and the second cam 4730 presses against the first pressing section 4602 of the corresponding pressing curved surface 4601, so that the two connecting rod members 462 remain in a flat state.The first rotating parts 452 of the two rotating parts 450 are respectively accommodated in the two receiving grooves 440 of the base 44, so that the two arc rails 4522 of each first rotating part 452 are respectively inserted into the corresponding two arc grooves 442; the linkage mechanism 46 and the limiting mechanism 47 are placed between the two connecting parts 455, and the guide rails 4620 of the two connecting rod parts 462 are respectively slidably inserted into the guide grooves 4550 of the two connecting parts 455, and the two connecting caps 4612, the two rotating shafts 4644 and the positioning rod 4657 are respectively inserted into the two adapter holes 445, the two connecting holes 446 and the fixing hole 447.

[0097] like Figure 10-13 As shown, when assembling the folding device 40, the back surfaces of the bases 44 of the two folding-assisting components 41 are placed on the two connecting portions 482 of the back cover 48, the central support member 421 is placed on the two bases 44, and a plurality of fasteners (e.g., screws) are inserted through the plurality of connecting holes 4214 and the corresponding positioning holes 443 and fastened to the corresponding fixing holes 4842, thereby connecting the two first connecting regions 4212 to the two folding-assisting components 41. The two side support members 423 are placed on opposite sides of the base 44, with the central support member 421 located between the two side support members 423. The two rotating rails 4556 of each connecting member 455 are rotatably received in the corresponding pair of rotating grooves 4234, and the adjustment shaft 4628 of the connecting rod 462 is inserted into the corresponding adjustment groove 4237. At this point, the rotation axis between the rotating member 450 and the base 44 is parallel to the axis of the rotating shaft, and the rotation axis between the rotating member 450 and the connecting member 455 is parallel to the axis of the rotating shaft. When the two side supports 423 are in a flattened state, the adjustment shaft 4628 is positioned in the second positioning section 4237b of the corresponding adjustment slot 4237, the positioning portion 4656 abuts the second limiting surface 4627, and the second cam 4730 is positioned in the corresponding first abutting section 4602, so that the folding device 40 remains in a flattened state. The front surfaces of the two side supports 423 and the middle support 421 are coplanar, preventing the side supports 423 from bending backward relative to the middle support 421. When the two side supports 423 are in a folded state, the adjustment shaft 4628 is located in the first positioning section 4237a of the corresponding adjustment slot 4237, the positioning portion 4656 abuts the first limiting surface 4626, and the front surfaces of the two side supports 423 and the middle support 421 form a teardrop shape, preventing the side supports 423 from further bending relative to the middle support 421.

[0098] In this embodiment, when the folding device 40 is in the flattened state, the second cam 4730 is positioned at the first abutting section 4602; when the folding device 40 is in the folded state, the second cam 4730 is positioned at the second abutting section 4604; and when the folding device 40 is in the hovering state, the second cam 4730 is positioned at the hovering section 4603. The second cam 4730 exerts an expansion force during the sliding process between the second abutting section 4604 and the hovering section 4603 of the abutting curved surface 4601. This expansion force is used to drive the second cam 4730 to automatically slide from the second abutting section 4604 to the hovering section 4603, causing the connecting rod 462 to automatically rotate relative to the base 44, thereby achieving automatic expansion of the folding device 40 from the folded state to the hovering state. This allows the electronic device 100 to automatically expand from the folded state to the hovering state. It can be understood that the flattened state means that the front faces of the two frames 21, the front faces of the middle support member 421 and the front faces of the side support members 423 are coplanar; the folded state means that the front faces of the middle support member 421 and the two side support members 423 form a teardrop-shaped space, and the front faces of the two frames 21 are parallel and spaced apart; the hovering state means that the front faces of the middle support member 421 and the front faces of the side support members 423 form any folded state except the coplanar and teardrop-shaped space, that is, the folded state of the electronic device 100 in which the angle between the front faces of the two frames 21 is greater than 0 degrees and less than 180 degrees; preferably, when the electronic device 100 is in the hovering state, the angle between the front faces of the two frames 21 is greater than 90 degrees and less than 150 degrees.

[0099] Please also refer to Figure 1-Figure 3The assembled folding device 40 is placed between the two frames 21. The connecting members 455 on opposite sides of the folding device 40 are respectively accommodated in the mounting slots 218 of the two frames 21, with each connecting member 455 connected to a corresponding mounting portion 2181. Specifically, a plurality of fasteners (such as screws) are respectively connected to the connecting members 455 through the mounting holes 2183. When the folding housing 20 is in the folded state, the first magnetic member 61 and the second magnetic member 65 attract each other. The attraction force between the first magnetic member 61 and the second magnetic member 65 is greater than the expansion force between the second cam of the folding device 40 and the abutting curved surface 4601, thereby maintaining the folded state of the folding housing 20. When the control member 67 controls the movement of the first magnetic member 61 relative to the second magnetic member 65, the first magnetic member 61 and the second magnetic member 65 repel each other. At the same time, the expansion force between the second cam 4730 and the top curved surface 4601 drives the second cam 4730 on the top curved surface 4601 to automatically slide to the hovering section 4603, causing the connecting rod 462 to automatically rotate relative to the base 44, so that the two frames 21 rotate relative to each other and automatically expand to a hovering state, thereby realizing the automatic expansion of the folding shell from the folded state to the hovering state. When the folding shell is in a flattened state, the first front surface 211 of the two frames 21, the front surface of the middle support member 421, and the front surfaces of the two side support members 423 are coplanar. The bendable area 31 of the flexible screen 30 is connected to the front surface of the folding device 40, and the two non-bending areas 33 are respectively connected to the first front surface 211 of the two frames 21.

[0100] Please also refer to Figure 1-Figure 3 and Figures 26-34When the electronic device 100 is bent, a bending force is applied to at least one of the two frames 21 of the electronic device 100, so that the rotating mechanism 45 connected to the two frames 21 rotates in a direction toward each other, and the folding device 40 is bent through the two folding auxiliary components 41, and the bendable area 31 of the flexible screen 30 bends along with the supporting component 42 of the folding shell 20. Specifically, if a bending force is applied to one of the frames 21, the one of the frames 21 drives the corresponding rotating mechanism 45 to rotate relative to the base 44 toward the side close to the flexible screen 30; the arc rail 4522 of the rotating member 450 rotates in the corresponding arc groove 442 to drive the corresponding connecting rod member 462 to rotate along the axis of the rotating shaft 461 relative to the base 44 toward the side close to the flexible screen 30. At the same time, the guide rail 4620 of the connecting rod member 462 slides in the guide groove 4550 of the corresponding connecting member 455, and the first sleeve 4622, the rotating shaft 461, the driving gear 4621 and the first cam 460 of the connecting rod member 462 rotate along the axis of the corresponding rotating shaft 461. The rotating driving gear 4621 drives the other driving gear 4621 to rotate through the gear set 464. The rotation of the other driving gear 4621 drives the corresponding rotating shaft 461, the first sleeve 4622, the first cam 460 and the connecting rod The body 4623 rotates, so that the two connecting rods 462 of the linkage mechanism 46 are synchronously moved closer to each other, and the two rotating mechanisms 45 are synchronously moved closer to each other; at the same time, the first cam 460 on each connecting rod 462 rotates to push the corresponding second cam 4730, so that the second cam 4730 slides from the first abutting section 4602 to the second abutting section 4604 on the corresponding abutting curved surface 4601, and the supporting member 473 slides axially along the rotating shaft 461 to squeeze the elastic member 475. The opposite ends of the elastic member 475 elastically push the supporting member 473 and the positioning member 476 respectively, and the first friction member 4770 is clamped between the gasket 478 and the positioning member 476, and the second friction member 4775 is clamped between the gasket 478 and the C-shaped buckle 4779, and the first friction member 4770 and the second friction member 4775 rotate relative to the gasket 478 and the positioning member 476 along the corresponding rotating shaft 461.During the bending process of the linkage mechanism 46, the first rotating portion 452 of the rotating member 450 rotates relative to the base 44 through the cooperation of the circular arc rail and the corresponding circular arc groove, the second rotating portion 453 of the rotating member 450 is rotatably connected to the corresponding connecting member 455 along the corresponding connecting shaft 451, and the adjusting shaft 4628 rotates from the second positioning section 4237b in the corresponding adjusting groove 4237 and slides to the first positioning section 4237a, and the two connecting rods 462 rotate along the axis of the corresponding rotating shaft 461 and move closer to each other to achieve the mutual adjustment of the two side support members 423. They move closer to each other, so that the folding device 40 is in a bent state, and the bendable area 31 of the flexible screen 30 bends to the bent state along with the folding device 40, until the first magnetic part 61 and the second magnetic part 65 on the two frames 21 are magnetically attracted to each other. At this time, the bendable area 31 is in a bent state and has a rebound force to drive the electronic device 100 to unfold. The magnetic attraction force between the first magnetic part 61 and the second magnetic part 65 is greater than the sum of the unfolding force between the second cam 4730 of the folding device 40 and the top curved surface 4601 and the rebound force of the bendable area 31, so that the electronic device 100 remains in the folded state.

[0101] In other bending methods of the electronic device 100, a bending force can also be applied to the two frames 21 at the same time. The two frames 21 respectively drive the two side support members 423 to rotate relative to the side close to the flexible screen 30, and the folding device 40 is used to realize the bending of the electronic device 100.

[0102] When the electronic device 100 needs to be flattened, the user can use one hand to operate the toggle key 672 to slide along the slide groove 217, so that the guide slide bar 674 moves along the guide groove 216 to drive the first shielding box 62 to slide along the first receiving groove 210, so that the multiple first magnets 610 move relative to the multiple second magnets 650, so that the first magnetic member 61 and the second magnetic member 65 repel each other, and the elastic member 475 elastically pushes the corresponding second sleeve 4732. The unfolding force between the second cam 4730 and the top curved surface 4601, the rebound force of the bendable area 31 and the magnetic repulsive force between the first magnetic member 61 and the second magnetic member 65 drive the folding device 40 to automatically unfold from the folded state to the hovering state, so that the two frames 21 automatically unfold to the hovering state. Specifically, the unfolding force, rebound force and repulsive force together drive the two connecting rods 462 of each folding assist component 41 to rotate synchronously relative to the base 44 and move away from each other, and each second cam 4730 automatically slides from the second abutting section 4604 to the hovering section 4603 on the corresponding abutting curved surface 4601, and the two driving gears 4621 rotate respectively relative to the gear group 464, so that the two connecting rods 462 automatically rotate along the axis of the corresponding rotating shaft 461 and move away from each other, thereby driving the two rotating mechanisms 45 to rotate synchronously relative to the base 44 and move away from each other, so as to realize the mutual distance between the two side support members 423, and each second cam 4730 automatically slides from the second abutting section 4604 to the hovering section 4603 on the corresponding abutting curved surface 4601, so that the folding device 40 automatically unfolds to the hovering state, the two frames 21 unfold to each other, and the bendable area 31 of the flexible screen 30 unfolds along with the folding device 40 of the folding shell 20 until the flexible screen 30 is flattened to the hovering state. The user continues to unfold the electronic device 100, and each second cam 4730 slides from the hovering section 4603 to the first abutting section 4602 on the corresponding abutting curved surface 4601, and the two driving gears 4621 rotate relative to the gear set 464, so that the two connecting rods 462 continue to rotate along the axis of the corresponding rotating shaft 461 and further move away from each other, so as to achieve further separation of the two side support members 423 from each other, so that the folding device 40 is unfolded to the flattened state, the two frames 21 are unfolded to the flattened state, and the bendable area 31 of the flexible screen 30 is further unfolded with the folding device 40 until the flexible screen 30 is unfolded to the flattened state.

[0103] During the unfolding process of the electronic device 100, the unfolding force between the second cam 4730 and the abutting curved surface 4601, combined with the rebound force of the bendable area 31, automatically unfolds the electronic device 100 from the folded state to the hovering state. The second cam 4730 automatically slides from the second abutting section 4604 to the hovering section 4603 on the corresponding abutting curved surface 4601. Each connecting rod 462 rotates the corresponding rotating shaft 461. The rotating shaft 461 rotates within the corresponding first guide hole 4652, the inner cavity of the second sleeve 4732, the second guide hole 4765, and the through hole 4782, driving the corresponding first friction member 4770 and second friction member 4775 to rotate, automatically unfolding the folding assist assembly 41 from the folded state to the hovering state. The folding assist component 41 is then further unfolded, so that the second cam 4730 slides from the suspended section 4603 to the first abutting section 4602, and the two connecting rods 462 rotate relative to the abutting member 473 and continue to move away from each other until the second cam 4730 is positioned at the first abutting section 4602, so that the folding assist component 41 is unfolded from the suspended state to the flattened state.

[0104] The folding device 40 of the electronic device 100 of the present invention can be automatically unfolded to a hovering state through the unfolding force between the second cam 4730 of the folding auxiliary component 41 and the top curved surface 4601, the rebound force of the bendable area 31 and the magnetic repulsion force between the first magnetic part 61 and the second magnetic part 65. The user can automatically flatten the electronic device 100 to a hovering state with one hand operation, which is convenient to use and improves the user experience; secondly, since the folding device 40 is small in size, the internal space occupied by the folding device 40 in the folding shell 20 is reduced, which is not only beneficial to the layout of other components such as the motherboard or battery in the electronic device 100, but also beneficial to miniaturization development.

[0105] Please also refer to Figure 35-Figure 39 The structure of another folding device in the present application is similar to the structure of the folding device 40 in any of the above-mentioned embodiments, except that: the shape of the first cam 460a of the another folding device is different from the shape of the first cam 460 of the folding device 40; specifically, the first cam 460a has a top curved surface 4601a on the side away from the first sleeve 4622, and the second cam 4730 can slidably abut against the top curved surface 4601a. When the folding device is in a non-flattened state, there is an unfolding force between the second cam 4730 and the top curved surface 4601a, and the unfolding force is used to drive the connecting rod 462 to rotate relative to the base 44 toward the flattened state of the folding device 40, so as to realize automatic unfolding of the folding device 40.

[0106] The first cam 460 includes at least one first protrusion 4605, and the top curved surface 4601a is provided at one end of the first protrusion 4605 facing the second cam 4730. The second cam 4730 includes at least one second protrusion 4731, and the second protrusion 4731 has a sliding surface 4733 facing the first cam 460, and the sliding surface 4733 slidably abuts against the top curved surface 4601a. The abutting curved surface 4601a includes a first abutting section 4602 and a second abutting section 4604 at opposite ends. When the folding device 40 is in the flattened state, the second cam 4730 abuts the first abutting section 4602. When the folding device 40 is in the folded state, the second cam 4730 abuts the second abutting section 4604. Under the thrust of the elastic member 475, the second cam 4730 automatically slides from the second abutting section 4604 to the first abutting section 4602, thereby driving the connecting rod 462 to rotate relative to the base 44 and flatten. When the folding device 40 is in the flattened state, the second cam 4730 abuts the first abutting section 4602. When the folding device 40 is in the folded state, the second cam 4730 abuts the second abutting section 4604. During the folding process of the folding device 40, the two connecting rods 462 rotate around the axis of the corresponding rotating shaft 461 relative to the base 44 and move closer to each other. The second cam 4730 slides from the first abutting section 4602 to the second abutting section 4604 on the corresponding abutting curved surface 4601 to push the supporting member 473 to slide along the axial direction of the rotating shaft 461 toward the side away from the connecting rod 462. The elastic member 475 is compressed, and the two rotating mechanisms 45 rotate synchronously relative to the base 44 and move closer to each other, so that the two side support members of the support assembly 42 are folded relative to the middle support member. During the flattening process of the folding device 40, the two elastic members 475 elastically push the supporting member 473 respectively, so as to push the supporting member 473 to slide along the axial direction of the rotating shaft 461 toward one side of the connecting rod member 462, so that the second cam 4730 automatically slides from the second supporting section 4604 to the first supporting section 4602 on the corresponding supporting curved surface 4601, and the two connecting rod members 462 automatically rotate relative to the base 44 around the axis of the corresponding rotating shaft 461 and move away from each other. The elastic member 475 is partially reset, and the two rotating mechanisms 45 synchronously rotate relative to the base 44 and move away from each other, so that the two side support members 423 of the support assembly 42 are respectively unfolded relative to the middle support member 421 until the second cam 4730 abuts against the corresponding first supporting section 4602, and the elastic member 475 continues to abut against the supporting member 473, so that the folding device 40 remains in a flattened state.

[0107] Specifically, the first protrusion 4605 also includes a first connecting curved surface 4606 connected to the first abutting section 4602 and a second connecting curved surface 4607 connected to the second abutting section 4604. The first abutting section 4602 and the first connecting curved surface 4606 have a smooth transition, and the second abutting section 4604 and the second connecting curved surface 4607 have a smooth transition. In this embodiment, the first cam 460 includes two first protrusions 4605, which are arranged along the circumference of the rotating shaft 461, and each first protrusion 4605 is provided with a top curved surface 4601a at one end facing the second cam 4730; the second cam 4730 includes two second protrusions 4731, which are arranged along the circumference of the rotating shaft 461, and each second protrusion 4731 has a sliding surface 4733 facing the corresponding first cam 460, and the two sliding surfaces 4733 of the second cam 4730 respectively slide against the two top curved surfaces 4601a of the first cam 460. Preferably, the two first protrusions 4605 of the first cam 460 are evenly spaced along the circumference of the rotation axis 461, and a first recess 4608 is formed between the two first protrusions 4605. The two second protrusions 4731 of the second cam 4730 are evenly spaced along the circumference of the rotation axis 461, and a second recess 4735 is formed between the two second protrusions 4731. As the second cam 4730 slides from the second abutting section 4604 of the corresponding abutting curved surface 4601a to the first abutting section 4602, an expansion force is generated between the second cam 4730 and the abutting curved surface 4601a, driving the connecting rod 462 to rotate relative to the base 44 and flatten it.

[0108] Optionally, the inclination angle of the abutting curved surface 4601a gradually increases from the second abutting segment 4604 to the first abutting segment 4602 , and the expansion force gradually increases as the second cam 4730 slides from the second abutting segment 4604 to the first abutting segment 4602 .

[0109] In other embodiments, the number of second protrusions 4731 on the second cam 4730 corresponds to the first protrusions 4605 on the corresponding first cam 460, and the first cam 460 includes more than three first protrusions 4605, which are evenly spaced along the circumference of the rotating shaft 461, and a first recessed portion 4608 is formed between each adjacent two first protrusions 4605; the second cam 4730 includes more than three second protrusions 4731, which are evenly spaced along the circumference, and a second recessed portion 4735 is formed between each adjacent two second protrusions 4731.

[0110] Optionally, the second abutting section 4604 of the abutting curved surface 4601a is closer to the supporting member 473 relative to the first abutting section 4602. Specifically, the first length L1 of the first abutting section 4602 extending axially along the rotating shaft 461 is smaller than the second length L2 of the second abutting section 4604 extending axially along the rotating shaft 461. The axial extension length of the first protrusion 4605 along the rotating shaft 461 gradually decreases from the second abutting section 4604 to the first abutting section 4602, and the inclination angle of the abutting curved surface 4601a gradually increases from the second abutting section 4604 to the first abutting section 4602. When the second protrusion 4731 automatically slides from the second abutting section 4604 to the first abutting section 4602 on the corresponding abutting curved surface 4601a, the expansion force between the second protrusion 4731 and the abutting curved surface 4601a gradually increases as the second cam 4730 slides from the second abutting section 4604 to the first abutting section 4602.

[0111] When the folding device 40a is bent from the flat state, one of the connecting rods 462 is bent toward the other connecting rod 462 relative to the supporting member 473. The one connecting rod 462 rotates along the axis of the corresponding rotating shaft 461, thereby driving the corresponding rotating shaft 461, the driving gear 4621, and the first cam 460 to rotate along the axis of the rotating shaft 461. The rotating shaft 461 rotates in the first guide slide hole 4652 corresponding to the positioning member 476, the second guide slide hole 4765 corresponding to the fixing member 465, and the through hole 4782 corresponding to the gasket 478. The rotating driving gear 4621 drives the other driving gear 4621 to rotate through the gear set 464. The rotation of the other driving gear 4621 drives the corresponding rotating shaft 461, the first sleeve 462, and the first sleeve 462. 2. The first cam 460 and the connecting rod body 4623 rotate, so that the two connecting rod members 462 of the linkage mechanism 46 synchronously approach each other; at the same time, each second cam 4730 slides from the first abutting section 4602 to the second abutting section 4604 on the corresponding abutting curved surface 4601a, and the supporting member 473 slides axially along the rotating shaft 461 to squeeze the elastic member 475, and the elastic member 475 elastically pushes the positioning member 476, so that the first friction member 4770 is clamped between the gasket 478 and the positioning member 476 and the second friction member 4775 is clamped between the gasket 478 and the C-shaped buckle 4779, and the first friction member 4770 and the second friction member 4775 rotate relative to the positioning member 476 and the gasket 478 along the corresponding rotating shaft 461.

[0112] When the folding device 40a is unfolded from the folded state, the two elastic members 475 elastically push the two second sleeves 4732 respectively, causing the second cam 4730 to slide against the corresponding abutting curved surface 4601. Since there is an unfolding force between the second cam 4730 and the corresponding abutting curved surface 4601a, which drives the connecting rod member 462 to rotate relative to the abutting member 473 and unfold, this unfolding force can drive the two connecting rod members 462 to rotate synchronously and automatically relative to the abutting member 473 and move away from each other. Each second cam 4730 automatically slides from the second abutting section 4604 to the first abutting section 4602 on the corresponding abutting curved surface 4601a. Each connecting rod member 462 drives the corresponding rotating shaft 461 to rotate. The rotating shaft 461 rotates in the corresponding second guide hole 4765, the inner cavity of the second sleeve 4732, the first guide hole 4652 and the through hole 4782, and drives the corresponding first friction member 4770 and second friction member 4775 to rotate.

[0113] It can be understood that the folding or flattening of the electronic device having the folding device 40 a is similar to the folding or flattening of the electronic device 100 described above, and will not be described in detail herein.

[0114] Please also refer to Figures 40-43The structure of the folding shell 20a in another embodiment of the present application is similar to the structure of the folding shell 20 in any of the above embodiments, except that: the first magnetic member 61a and the second magnetic member 65a of the folding shell 20a are different from the first magnetic member 61 and the second magnetic member 65 of the folding shell 20; specifically, at least one of the first magnetic member 61a and the second magnetic member 65a of the folding shell 20a is an electromagnet, and the other is a magnet; after the control member 67a controls the electromagnet to be energized, the magnetic poles between the first magnetic member 61a and the second magnetic member 65a are the same, forming a repulsive force; after the control member 67a controls the electromagnet to be de-energized, the magnetic poles between the first magnetic member 61a and the second magnetic member 65a are opposite, forming a magnetic attraction force. Optionally, the first magnetic component 61a is an electromagnet electrically connected to the circuit board of the folding shell 20, the second magnetic component 65a is a magnet, and the control component 67a is a button electrically connected to the circuit board, and the electromagnet is controlled to be powered on or off by operating the button; when the folding shell 20a is in a folded state, the operation control component 67a controls the first magnetic component 61a to be powered off, so that the magnetic poles between the first magnetic component 61a and the second magnetic component 65a are opposite and attract each other, so that the two frames 21 of the folding shell 20a remain in the folded state; when the operation control component 67a controls the first magnetic component 61a to be powered on, the magnetic poles between the first magnetic component 61a and the second magnetic component 65a are the same and repel each other, so that the two frames 21 of the folding shell 20a rotate relative to each other and automatically unfold. Optionally, the second magnetic component 65a is an electromagnet electrically connected to the circuit board of the folding shell 20, the first magnetic component 61a is a magnet, and the control component 67a is a button electrically connected to the circuit board, and the electromagnet is controlled to be powered on or off by operating the button; when the folding shell 20a is in a folded state, the operation control component 67a controls the second magnetic component 65a to be powered off, so that the magnetic poles between the first magnetic component 61a and the second magnetic component 65a are opposite and attract each other, so that the two frames 21 of the folding shell 20a remain in the folded state; when the operation control component 67a controls the second magnetic component 65a to be powered on, the magnetic poles between the first magnetic component 61a and the second magnetic component 65a are the same and repel each other, so that the two frames 21 of the folding shell 20a rotate relative to each other and automatically unfold.

[0115] Optionally, the first magnetic member 61a and the second magnetic member 65a are both electromagnets. After the control member 67a controls the first magnetic member 61a and the second magnetic member 65a to be energized, the magnetic poles between the first magnetic member 61a and the second magnetic member 65a are the same to form a repulsive force; after the control member 67a controls one of the first magnetic member 61a and the second magnetic member 65a to be deenergized, the magnetic poles between the first magnetic member 61a and the second magnetic member 65a are opposite to form a magnetic attraction force. Specifically, the first magnetic member 61a and the second magnetic member 65a are both electromagnets electrically connected to the circuit board of the folding shell 20a, and the control member 67a is a button electrically connected to the circuit board. By operating the button, the power on or off of the two electromagnets can be controlled; when the folding shell 20a is in the folded state, the operation control member 67a controls the first magnetic member 61a or the second magnetic member 65a to be de-energized, so that the magnetic poles between the first magnetic member 61a and the second magnetic member 65a are opposite and attract each other, so that the two frames 21 of the folding shell 20a remain in the folded state; when the operation control member 67a controls the first magnetic member 61a and the second magnetic member 65a to be energized, the magnetic poles between the first magnetic member 61a and the second magnetic member 65a are the same and repel each other, so that the two frames 21 of the folding shell 20a rotate relative to each other and automatically unfold.
