Therefore, "module", "component", or "unit" can be used interchangeably.

[0068] The intelligent terminal can be implemented in various forms. For example, the intelligent terminal described in the present application can include intelligent terminals such as mobile phones, tablet computers, laptop computers, palmtop computers, personal digital assistants (PDAs), portable media players (PMPs), navigation devices, wearable devices, smart bracelets, pedometers, etc., as well as fixed terminals such as digital TVs and desktop computers.

[0069] The flexible screen, that is, the flexible display screen, is used to display images. Exemplarily, the flexible screen can be an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode (AMOLED) display screen, a mini organic light-emitting diode display screen, a micro organic light-emitting diode display screen, a micro-organic light-emitting diode display screen, or a quantum dot light-emitting diode (QLED) display screen.

[0070] Considering that when the intelligent terminal is in the folded state, it is difficult to open it with one hand. Especially when the user is carrying a heavy object in one hand and needs to switch the intelligent terminal from the folded state to the unfolded state for use, it is very inconvenient.

[0071] In view of this, a folding device and an intelligent terminal provided by the present application, by setting a switch member, under the action of an external force, the switch member moves towards the inside of the base, driving the rotating assembly to rotate, so as to reduce the pre-tightening force of the folding device. The pre-tightening force of the folding device is not sufficient to keep the folding device stably in the folded state. Under the action of the rebounding force of the flexible screen, the folding device opens from the folded state. The user manually presses the switch member, which facilitates the user's one-handed operation, realizes the opening of the folding device from the folded state, and improves the convenience of operation.

[0072] The following describes a folding device and an intelligent terminal provided by an embodiment of the present application with reference to the accompanying drawings.

[0073] Refer to Figure 1 and Figure 2 As shown, the present utility model provides a folding device, including: a base 10, a rotating assembly 20 and a switch member 30. An installation hole 11 is formed in the base 10. The rotating assembly 20 is rotatably connected to the base 10. The rotating assembly 20 is located on at least one side of the base 10. The switch member 30 is movably arranged in the installation hole 11. The switch member 30 is configured to move towards the inside of the base 10 under the action of an external force and drive the rotating assembly 20 to rotate, so that the folding device opens from the folded state.

[0074] For a folding device provided by the present utility model, by setting the switch member 30, under the action of an external force, the switch member 30 moves towards the inside of the base 10, driving the rotating assembly 20 to rotate, so as to reduce the pre-tightening force of the folding device. The pre-tightening force of the folding device is not sufficient to keep the folding device stably in the folded state. Under the action of the rebounding force of the flexible screen, the folding device opens from the folded state. The user manually presses the switch member 30, which facilitates the user's one-handed operation, realizes the opening of the folding device from the folded state, and improves the convenience of operation.

[0075] In a possible implementation manner, refer to Figure 3 、 Figure 4 and Figure 5 As shown, the rotating assembly 20 includes a torsion member 21 and a rotating unit. Both the torsion member 21 and the rotating unit are rotatably arranged on the base 10. The torsion member 21 is slidably matched with the rotating unit. The switch member 30 is used to drive the torsion member 21 to rotate.

[0076] In a possible implementation manner, refer to Figure 6 and Figure 7As shown, the folding device further includes a damping assembly 40. The damping assembly 40 includes a mating part and an elastic part 42. The base 10 has a mounting shaft 12. The torsion part 21 includes a connecting arm 211, a first cam 212, and a first gear 213. Both the first cam 212 and the first gear 213 are connected to the first end of the connecting arm 211. Both the first cam 212 and the first gear 213 are rotatably arranged on the mounting shaft 12, and the first cam 212 abuts against the mating part. The end faces of the first cam 212 and the mating part that abut against each other have corresponding convex teeth and tooth grooves. The elastic part 42 is used to push the mating part towards the first cam 212. The second end of the connecting arm 211 is slidably matched with the rotating unit. The first end and the second end of the connecting arm 211 are opposite ends of the connecting arm 211.

[0077] The damping assembly 40 cooperates with the torsion part 21 to achieve the hovering effect of the folding device, so that the folding device remains stable in the unfolded state, folded state, etc., and prevents the folding angle of the folding device from being easily changed, thereby improving the use effect of the intelligent terminal.

[0078] In a possible implementation manner, the elastic part 42 can be a compression spring or an elastic sleeve, etc. The elastic part 42 can be sleeved on the mounting shaft 12 to prevent the elastic part 42 from falling off.

[0079] In a possible implementation manner, the connecting arm 211, the first cam 212, and the first gear 213 are an integrally connected overall structure. The first cam 212 and the first gear 213 are arranged at intervals. There is an interval groove 214 between the first cam 212 and the first gear 213.

[0080] In a possible implementation manner, refer to Figure 8 As shown, the first cam 212 has a plurality of first convex teeth 2121 and a plurality of first tooth grooves 2122 that are spaced apart from each other. The plurality of first convex teeth 2121 and the plurality of first tooth grooves 2122 are on the end face of the first cam 212 facing the mating part and are spaced apart with the central axis of the first cam 212 as the center.

[0081] In a possible implementation manner, refer to Figure 7 As shown, the mounting hole 11 opened in the base 10 is a through hole, and the mounting hole 11 penetrates the inner wall surface and the outer wall surface of the base 10.

[0082] For the convenience of installing the damping assembly 40, refer to Figure 7As shown, the base 10 has a first stop portion 13 and a second stop portion 14. The first stop portion 13 and the second stop portion 14 may be arranged at intervals along the length direction of the base 10. At least part of the mounting shaft 12 is located between the first stop portion 13 and the second stop portion 14. Both the first cam 212 and the mating member are located between the first stop portion 13 and the second stop portion 14. The elastic member 42 abuts between the mating member and the first stop portion 13, and the first cam 212 abuts between the second stop portion 14 and the mating member. Under the elastic force of the elastic member 42, the elastic member 42 pushes the mating member close to the first cam 212, so that the mating member and the first cam 212 remain in mutual abutment.

[0083] In a possible implementation manner, the mounting hole 11 may be a circular hole, a square hole, a polygonal hole, etc.

[0084] Embodiment 1

[0085] In this embodiment, refer to Figure 9 、 Figure 10 and Figure 11 As shown, the switch member 30 includes a first switch 31. A limiting flange 311 is provided on the outer wall of the first switch 31, and the limiting flange 311 abuts against the inner end surface of the mounting hole 11.

[0086] In a possible implementation manner, the first switch 31 may be columnar. The limiting flange 311 may be a convex column protruding from the outer wall of the first switch 31, or a convex ring protruding from the outer wall of the first switch 31. The limiting flange 311 cannot pass through the mounting hole 11, achieving the effect of preventing the first switch 31 from coming out of the mounting hole 11.

[0087] In a possible implementation manner, the cross-sectional shape of the first switch 31 is the same as the cross-sectional shape of the mounting hole 11.

[0088] In a possible implementation manner, refer to Figure 12 and Figure 13 As shown, the mating member is a first mating member 41. The first mating member 41 includes a second cam 411 and an extension arm 412 connected to the second cam 411. The extension arm 412 extends radially along the second cam 411 above the mounting hole 11. The first switch 31 is slidably disposed in the mounting hole 11 and abuts against one side of the extension arm 412 facing the base 10.

[0089] When the folding device is in the folded state, one end of the first switch 31 abuts against the surface of the extension arm 412 facing the base 10, and the other end of the first switch 31 extends out of the outer end of the mounting hole 11 or is flush with the outer end of the mounting hole 11, facilitating the user to press the first switch 31, causing the first switch 31 to move inwardly towards the mounting hole 11. When the user presses the first switch 31, the first switch 31 pushes the extension arm 412, causing the extension arm 412 to drive the first fitting 41 to rotate circumferentially around the mounting shaft 12 as a whole. During the rotation of the first fitting 41, the first fitting 41 cooperates with the torsion member 21 to drive the torsion member 21 to rotate circumferentially around the mounting shaft 12, and the torsion member 21 drives the rotating unit to rotate on both sides of the base 10, realizing the opening of the folding device from the folded state.

[0090] In a possible implementation manner, referring to Figure 12 , Figure 13 and Figure 14 as shown, the second cam 411 has a plurality of second convex teeth 4111 and a plurality of second tooth grooves 4112, and the plurality of second convex teeth 4111 and the plurality of second tooth grooves 4112 are distributed at intervals on the end surface of the second cam 411 facing the first cam 212, centered on the central axis of the second cam 411.

[0091] When the folding device is in the unfolded state or the folded state, the first convex tooth 2121 corresponds to the second tooth groove 4112, the second convex tooth 4111 corresponds to the first tooth groove 2122, and the elastic member 42 is compressed. Under the action of its own elastic force, the elastic member 42 causes the second cam 411 and the first cam 212 to remain in contact, thus realizing the hovering effect and keeping the folding device in the unfolded state or the folded state.

[0092] When pressing the first switch 31, the first switch 31 moves towards the inside of the base 10. The first switch 31 pushes the extension arm 412, causing the extension arm 412 to drive the second cam 411 to rotate circumferentially around the mounting shaft 12. The first convex tooth 2121 disengages from contact with the second tooth groove 4112, and the second convex tooth 4111 of the second cam 411 disengages from contact with the first tooth groove 2122, reducing the pre-tightening force between the first cam 212 and the second cam 411, which helps to open the folding device from the folded state.

[0093] In a possible implementation manner, rotating assemblies 20 are provided on both sides of the base 10, and the torsion members 21 of the two rotating assemblies 20 are arranged oppositely; referring to Figure 10 and Figure 11 as shown, when the folding device is in the folded state, there is a gap between the ends of the two extension arms 412 relative to the second cam 411, which is to prevent interference between the two extension arms 412.

[0094] Referring to Figure 13As shown, when the folding device is opened from the folded state, one end of the two extension arms 412 abuts against each other relative to the second cam 411. At this time, the first switch 31 cannot continue to push the extension arm 412, so the extension arm 412 will not drive the second cam 411 to continue rotating. The purpose is to limit the depth of the first switch 31 entering the mounting hole 11 and make the first fitting 41 remain stationary relative to the torsion member 21.

[0095] In a possible implementation manner, referring to Figure 10 and Figure 11 As shown, the folding device further includes a transmission assembly 80. The transmission assembly 80 includes two second gears 81 that mesh with each other, and the two second gears 81 are respectively meshed with the two first gears 213. The transmission assembly 80 is used to make the two rotating assemblies 20 swing relative to each other. When one torsion member 21 rotates, the first gear 213 rotates, and the first gear 213 makes the other torsion member 21 rotate through the two meshing second gears 81, improving the folding and unfolding efficiency of the folding device.

[0096] In a possible implementation manner, referring to Figure 7 、 Figure 15 and Figure 16 As shown, the rotating assembly 20 includes a torsion member 21 and a rotating unit. Among them, the rotating unit includes a guiding member 22. Referring to Figure 15 As shown, the rotating unit further includes a rotating member 23, a linkage member 24, and a support plate 25. The rotating member 23 includes a first rotating portion 231 and a second rotating portion 232 that are connected to each other. The first rotating portion 231 is rotatably arranged on the guiding member 22, and the second rotating portion 232 is rotatably connected to the linkage member 24. The connecting arm 211 is slidably arranged in the linkage member 24, and the support plate 25 is fixedly connected to the side of the rotating member 23 facing away from the guiding member 22.

[0097] In order to facilitate the sliding connection between the connecting arm 211 and the linkage member 24, sliding blocks 2111 are arranged on both sides of the connecting arm 211, and a sliding groove 241 that cooperates with the sliding block 2111 is formed in the linkage member 24, enabling the connecting arm 211 and the linkage member 24 to achieve relative sliding.

[0098] In a possible implementation manner, the guiding member 22 is fixedly arranged on the base 10 by, but not limited to, screws, bolts, snap connections, or pasting, etc. The guiding member 22 serves to define the rotation trajectory of the rotating member 23.

[0099] In one possible implementation, a first connecting groove 221 is provided in the guide member 22, the first rotating part 231 of the rotating member 23 extends into the first connecting groove 221 and rotates in the first connecting groove 221, the side wall of the first connecting groove 221 is provided with a first guide structure 2211, and second guide structures 2311 are provided on both sides of the first rotating part 231. One of the first guide structure 2211 and the second guide structure 2311 is a guide groove, and the other is a guide protrusion. The guide protrusion extends into the guide groove and slides along the guide groove, which can prevent the rotating member 23 from disengaging from the guide member 22 and guide the movement of the rotating member 23.

[0100] Optionally, the guide groove can be an arc-shaped groove, and the guide protrusion can be an arc-shaped protrusion. The center of the guide groove coincides with the center of the guide protrusion, which ensures the accuracy of rotation. The center of the guide groove and the center of the guide protrusion are located on the side of the rotating part 23 away from the base 10. Of course, the guide protrusion can also be a cylindrical protrusion.

[0101] In a possible implementation, a second connection groove 242 is provided in the linkage member 24, and the second rotating part 232 of the rotating member 23 rotates in the second connection groove 242. A first guide structure 2421 is provided on the inner side wall of the second connection groove 242, and second guide structures 2321 are provided on both sides of the second rotating part 232. One of the first guide structure 2421 and the second guide structure 2321 is a guide groove, and the other is a guide protrusion. The guide protrusion extends into the guide groove and slides along the guide groove, which can prevent the rotating member 23 from being separated from the linkage member 24 and play a guiding role in the relative movement of the rotating member 23 and the linkage member 24.

[0102] Among them, the guide groove can be an arc-shaped groove, and the guide protrusion can be an arc-shaped protrusion. The center of the guide groove coincides with the center of the guide protrusion, which ensures the accuracy of rotation.

[0103] Embodiment 2

[0104] refer to Figure 6 , Figure 17 and Figure 18 As shown, the switch member 30 includes a second switch 32, and the second switch 32 includes a pressing portion 321 and an acting portion 322 that are connected to each other. The pressing portion 321 is slidably arranged in the mounting hole 11, and the acting portion 322 extends between the two first gears 213. A rack portion 323 is arranged on the side wall of the acting portion 322 facing the first gear 213, and the rack portion 323 is meshed with the first gear 213.

[0105] In one possible implementation, reference Figure 7 andFigure 18 As shown, the mating part is the second mating part 43. The second mating part 43 includes a third cam 431. The third cam 431 is fixedly arranged on the base 10. The end faces of the third cam 431 and the first cam 212 that are in mutual contact are both provided with correspondingly mating convex teeth and tooth grooves.

[0106] To prevent the third cam 431 from rotating and facilitate the installation and fixation of the third cam 431, the two third cams 431 are connected by a fixing part 432, so that the two third cams 431 are connected into an integral structure. After the two third cams 431 are sleeved on the mounting shaft 12, the third cam 431 can be effectively prevented from rotating around the mounting shaft 12.

[0107] In a possible implementation manner, the first cam 212 has a plurality of first convex teeth 2121 and a plurality of first tooth grooves 2122 that are spaced apart from each other. The plurality of first convex teeth 2121 and the plurality of first tooth grooves 2122 are spaced apart along the edge of the first cam 212 on the end face of the first cam 212 facing the mating part.

[0108] In a possible implementation manner, the third cam 431 has a plurality of third convex teeth 4311 and a plurality of third tooth grooves 4312. The plurality of third convex teeth 4311 and the plurality of third tooth grooves 4312 are on the end face of the third cam 431 facing the first cam 212 and are spaced apart around the central axis of the third cam 431.

[0109] The first convex teeth 2121 correspond to the third tooth grooves 4312, and the first tooth grooves 2122 correspond to the third convex teeth 4311. When the second switch 32 is pressed, the third cam 431 rotates a preset angle relative to the first mating part 41. The first convex teeth 2121 disengage from the contact with the third tooth grooves 4312, and the third convex teeth 4311 disengage from the contact with the first tooth grooves 2122, which can reduce the pre-tightening force of the folding device in the folded state. Under the action of its own elastic force, the elastic member 42 enables the third cam 431 and the first cam 212 to remain in contact, so that the unfolding angle of the folding device is kept stable.

[0110] In this embodiment, referring to Figure 18 and Figure 19 As shown, the rack portion 323 meshes with the first gear 213. When the second switch 32 is pushed towards the inside of the base 10, the rack portion 323 drives the first gear 213 to rotate, and the torsion member 21 rotates as a whole. Therefore, the first cam 212 also rotates relative to the third cam 431, so that the first convex teeth 2121 of the first cam 212 disengage from the contact with the third tooth grooves 4312 of the third cam 431, and the pre-tightening force is reduced. Therefore, the folding device automatically opens a small angle from the folded state, making it easier to open the folding device.

[0111] In a possible implementation manner, a limiting platform 324 is provided at the connection position of the pressing part 321 and the acting part 322, and the limiting platform 324 abuts against the inner end face of the mounting hole 11. The limiting platform 324 serves to prevent the second switch 32 from disengaging from the mounting hole 11.

[0112] In a possible implementation manner, the cross-sectional shape of the pressing part 321 is the same as that of the mounting hole 11. The cross-sectional area of the pressing part 321 is smaller than that of the acting part 322, so that a limiting platform 324 is formed at the connection position of the pressing part 321 and the acting part 322.

[0113] Reference Figure 20 and Figure 21 As shown in the figure, the present application further provides an intelligent terminal, including a first main body 50, a second main body 60, and the above-mentioned folding device, and the folding device is connected between the first main body 50 and the second main body 60.

[0114] An intelligent terminal provided by the present application further includes a flexible screen, and the flexible screen is connected between the first main body 50 and the second main body 60.

[0115] In a possible implementation manner, the intelligent terminal further includes a magnetic component 70. The magnetic component 70 includes a first magnetic member 71 and a second magnetic member 72. The first magnetic member 71 is disposed on the first main body 50, the second magnetic member 72 is disposed on the second main body 60, and the magnetic properties of the first magnetic member 71 and the second magnetic member 72 are opposite, so that the first main body 50 and the second main body 60 are magnetically attracted to each other.

[0116] In a possible implementation manner, for example, both the first magnetic member 71 and the second magnetic member 72 can be magnets, or one of them can be a magnet and the other can be a part containing metallic iron to achieve the magnetic attraction between the first magnetic member 71 and the second magnetic member 72.

[0117] Reference Figure 20 As shown in the figure, when the intelligent terminal is in the folded state, the magnetic attraction force between the first magnetic member 71 and the second magnetic member 72 is F1, the clamping force of the folding device is F2, and the rebounding force of the flexible screen is F3. When pressing the switch member 30 towards the inside of the base 10, the clamping force F2 of the folding device decreases, and F1 remains unchanged, so that the sum of F1 and F2 changes from F3 < F1 + F2 to F3 > F1 + F2. Under the action of the rebounding force F3 of the flexible screen, the intelligent terminal automatically opens.

[0118] An intelligent terminal provided by the present application realizes the automatic opening of the intelligent terminal from the folded state, which is convenient for the user to operate and open with one hand and does not cause additional energy consumption.
