At this time, if the folding screen device falls, the hinge mechanism part will first contact the ground and be hit. The middle frame moves toward the ground under the action of inertia, which may cause the middle frame to drive the screen to shift, causing the folding screen to be delaminated, damaged and other problems.

[0046] As shown in the background technology, in the prior art, the smart terminal includes a folding screen, a hinge mechanism and a middle frame. The hinge mechanism is arranged in the middle of the folding screen. The two folding areas of the folding screen rotate around the hinge mechanism to achieve folding and unfolding. The middle frame is connected to the folding area of ​​the folding screen to support the screen.

[0047] In the prior art, when the folding screen is fully folded, the hinge mechanism and the edge of the middle frame are not on the same plane. At this time, if the smart terminal falls, the hinge mechanism will first contact the ground and be hit. The middle frame moves toward the ground under the action of inertia, which may cause the middle frame to drive the screen to shift, causing the folding screen to be delaminated, damaged, and other problems.

[0048] In view of the above technical problems, the embodiment of the present application provides a hinge mechanism and a smart terminal, wherein the hinge mechanism includes a base, a synchronous rotation component and a push component, wherein the synchronous rotation component is used to connect with the middle frame on the smart terminal, and the synchronous rotation component is rotatably arranged on two opposite sides of the base, and the synchronous rotation component is driven by the middle frame to rotate relative to the base when the folding screen is folded and unfolded. The push component is configured such that when the hinge mechanism is in a folded state, the push component part abuts against the middle frame, thereby forming a limit fit with the middle frame to hinder the movement of the middle frame, and when the hinge mechanism is in an unfolded state, the push component is separated from the middle frame and does not affect the rotation of the synchronous rotation component. In this way, when the smart terminal falls in the folded state and causes the hinge mechanism to contact the ground first, the push component on the hinge mechanism cooperates with the middle frame to prevent the middle frame from moving toward the ground under the action of inertia, which is beneficial to protecting the folding screen from damage and improving the drop resistance of the smart terminal.

[0049] The following specific embodiments are used to describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings:

[0050] It should be noted that the hinge mechanism provided in the embodiment of the present application can be applied to various smart terminals.

[0051] See also Figures 1 to 6 , Fig.11 and Fig.14 As shown, the hinge mechanism of the embodiment of the present application is used for a smart terminal. The smart terminal includes two middle frames 10 located on both sides of the hinge mechanism. The hinge mechanism includes: a base 100, a synchronous rotation component 200 and a push component 300. The synchronous rotation component 200 can be set to be symmetrically arranged on the base 100 and is rotatably connected to the base 100. The synchronous rotation component 200 rotates relative to the base 100 to switch the hinge mechanism between the folded and unfolded states. The push component 300 is configured so that when the hinge mechanism is in the folded state, the push component 300 partly abuts against the middle frame 10 of the hinge mechanism.

[0052] In the embodiments of the present application, Figure 1 The X direction is the first direction, the Y direction is the second direction, the smart terminal includes two middle frames 10 and a folding screen 20, two folding areas are symmetrically arranged on the folding screen 20, the chain mechanism is used to be arranged between the two folding areas, and the two screen middle frames 10 are respectively arranged on the two folding areas.

[0053] Optionally, the structure of the base 100 and the rotational connection method between the synchronous rotation component 200 and the base 100 are not limited in the embodiments of the present application. For example, an installation space 110 can be set in the base 100, and a rotating shaft 500 is respectively set on the two opposite sides of the installation space 110 along the first direction, and the two rotating shafts 500 extend along the second direction. The synchronous rotation components 200 are set to two corresponding to the rotating shafts 500, and the two synchronous rotation components 200 are respectively mounted on the two rotating shafts 500 and can be rotatably set around the corresponding rotating shafts 500. In addition, the two synchronous rotation components 200 are respectively connected to the two screen middle frames 10, so that when the folding screen 20 is folded or unfolded, the folding screen 20 drives the two synchronous rotation components 200 to rotate around the rotating shafts 500 relative to the base 100 through the screen middle frame 10.

[0054] When the synchronous rotating assembly 200 rotates relative to the base 100, the relative position of the base 100 and the middle frame 10 also changes. When the middle frame 10 and the base 100 are rotated to be perpendicular, the folding screen 20 is completely folded up, but at this time, the base 100 and the side of the middle frame 10 close to the base 100 are not on the same plane, and the base 100 protrudes from the middle frame 10. At this time, if the smart terminal falls, the base 100 will first contact the ground and be hit, and because there is a gap between the middle frame 10 and the ground, the middle frame 10 will tend to move toward the ground under the action of inertia, and the misalignment of the middle frame 10 will cause the folding screen 20 to be delaminated, damaged, and other problems.

[0055] Therefore, a push component 300 is provided, and at least two push components 300 can be provided, and are in transmission connection with the synchronous rotation component 200. The push component 300 is partially provided in the installation space 110 and is slidably matched with the base 100. When the synchronous rotation component 200 rotates, the push component 300 at least partially slides relative to the base 100. When in the folded state, the push component 300 partially cooperates with the middle frame 10 to limit the position. In this way, when the smart terminal falls and the base 100 contacts the ground first, the push component 300 can limit the position of the middle frame 10 and prevent the middle frame 10 from moving toward the ground, thereby protecting the folding screen 20, which is beneficial to improving the drop resistance of the smart terminal; when in the unfolded state, the push component 300 is separated from the middle frame 10 to avoid affecting the rotation of the middle frame 10, and ensure that the folding screen 20 can be smoothly unfolded or folded.

[0056] Therefore, when the smart terminal falls and the hinge mechanism is hit first, the push component 300 partly cooperates with the screen middle frame 10 to prevent the middle frame 10 from moving toward the ground, thereby avoiding displacement of the middle frame 10 relative to the hinge mechanism, which is beneficial to protecting the folding screen 20 from damage and improving the drop resistance of the smart terminal.

[0057] In some possible implementations, see Figures 1 to 6 and Figures 11 to 13 As shown, the hinge mechanism of the embodiment of the present application is constructed to switch between a folded state and an unfolded state. The synchronous rotation component 200 may include a driving structure 210 that rotates around the rotating axis 500 in the installation space 110. The synchronous rotation component 200 is rotationally connected to the base 100 through the driving structure 210; the driving structure 210 of the synchronous rotation component 200 is in transmission cooperation with the push component 300. When the synchronous rotation component 200 rotates relative to the base 100, the push component 300 partially moves toward or away from the middle frame 10.

[0058] Optionally, in the folded state, the synchronous rotation component 200 is perpendicular to the base 100, and in the unfolded state, the synchronous rotation component 200 and the base 100 are located on the same plane. Therefore, in the folded state, the base 100 protrudes more, and the smart terminal is more likely to have the problem of displacement of the middle frame 10 when it falls. Therefore, the push component 300 is configured to partially move toward the middle frame 10 during the folding process, and in the folded state, this part is in the first position and forms a limit fit with the middle frame 10 to prevent the middle frame 10 from causing the folding screen 20 to be dislocated. During the unfolding process, the push component 300 partially moves away from the middle frame 10, and in the unfolded state, this part is in the second position, and the push component 300 is separated from the middle frame 10, so that the middle frame 10 drives the synchronous rotation component 200 to rotate relative to the base 100 to avoid interference with the rotation of the push component 300.

[0059] Optionally, the limiting cooperation between the push component 300 and the middle frame 10 can be that the push component 300 is partially inserted into the corresponding groove of the middle frame 10, or that the push component 300 is partially abutted against the structure of the middle frame 10, etc. The specific limiting cooperation method is not limited in the embodiment of the present application, and it is sufficient to prevent the middle frame 10 from moving relative to the base 100.

[0060] In some possible implementations, see Figure 1 , Figure 6 , Fig. 9 , Fig.10 and Fig.11 As shown, a limiting groove 11 is provided on one side of the middle frame 10 close to the base 100 of the embodiment of the present application. When the hinge mechanism is in a folded state, the push assembly 300 partially extends into the limiting groove 11 and interferes with the middle frame 10 along the second direction to form a limiting fit; in the unfolded state, the push assembly 300 exits the limiting groove 11 to ensure that the middle frame 10 can rotate smoothly.

[0061] Optionally, a limiting groove 11 is provided on the middle frame 10. In the folded state, the push assembly 300 is in the first position, and the push assembly 300 is pushed by the driving structure 210 to partially extend into the limiting groove 11 and interfere with the middle frame 10 along the second direction, thereby preventing the middle frame 10 from moving along the third direction. The third direction is Fig.10 In the middle Z direction, in the unfolded state, the push assembly 300 is located at the second position, and the push assembly 300 exits the limiting groove 11 to avoid affecting the rotation of the middle frame 10 .

[0062] In some possible implementations, see Figures 1 to 6 and Fig.11 As shown, the push-pull assembly 300 of the embodiment of the present application includes: a push-pull member 310 and a transmission member 320. The push-pull member 310 is movably arranged in the installation space 110 along a first direction. The transmission member 320 is arranged in the installation space 110 and is arranged along a second direction with the synchronous rotation assembly 200. The transmission member 320 is transmission-connected with the push-pull member 310, and the transmission member 320 and the driving structure 210 of the synchronous rotation assembly 200 can be separated and matched; in the folded state, the driving structure 210 of the synchronous rotation assembly 200 drives the push-pull member 310 to move through the transmission member 320.

[0063] Optionally, the push assembly 300 further includes a push member 310 and a transmission member 320, wherein two push members 310 are provided, the push member 310 is provided in the installation space 110 and slidably cooperates with the base 100, the transmission member 320 is provided in the installation space 110, and the transmission member 320 is transmission-connected with the push member 310. In the unfolded state, the drive structure 210 is separated from the transmission member 320, and the transmission member 320 does not move, so that the push member 310 is maintained in the second position, and the push member 310 is in contact with the middle frame 10. Separation avoids affecting the rotation of the middle frame 10 and ensures that the folding screen 20 can be smoothly unfolded or folded; when the synchronous rotating component 200 gradually rotates from the unfolded state to the folded state, the driving structure 210 contacts the transmission member 320 and pushes the transmission member 320 to move relative to the base 100 along the second direction, and the transmission member 320 pushes the push member 310 to move along the first direction, so that the push member 310 reaches the first position, and the push member 310 cooperates with the middle frame 10 to limit the middle frame 10, thereby supporting the middle frame 10 and preventing the middle frame 10 from shifting.

[0064] Optionally, the push member 310 may include a limiting portion 313. When the middle frame 10 rotates from the unfolded state to the folded state, the push member 310 reaches the second position under the push of the transmission member 320, and the limiting portion 313 is inserted into the limiting groove 11 to form a limiting fit with the limiting groove 11. When the middle frame 10 rotates from the folded state to the unfolded state, the side wall of the limiting groove 11 moves relative to the limiting portion 313 of the push member 310, thereby pushing the push member 310 to move to the first position, and the push member 310 pushes the transmission member 320 to reset.

[0065] In some possible implementations, see Figures 1 to 6 , Figure 8 , Fig.13 and Fig.14 As shown, the hinge mechanism of the embodiment of the present application also includes a rotating shaft 500, which is arranged on two opposite sides of the base 100, and the driving structure 210 is rotatably connected to the rotating shaft 500; the transmission member 320 is respectively provided with first through holes 321 corresponding to the rotating shaft 500 at both ends along the first direction, and a second through hole 212 corresponding to the rotating shaft 500 is provided on the driving structure 210 of each synchronous rotating component 200, and each rotating shaft 500 is sequentially penetrated by the corresponding first through hole 321 and the second through hole 212, so that the transmission member 320 slides relative to the rotating shaft 500 along the second direction, and the synchronous rotating component 200 rotates around the rotating shaft 500.

[0066] Optionally, a first through hole 321 is opened on the transmission member 320, and the rotating shaft 500 is inserted into the first through hole 321, which can limit the moving path of the transmission member 320, ensure that the transmission member 320 slides along the second direction, and avoid the sliding path of the transmission member 320 from being offset, which is beneficial to improving the stability of the hinge mechanism structure.

[0067] In some possible implementations, see Figures 1 to 8 and Figure 12 to Figure 14 As shown, the driving structure 210 of the embodiment of the present application is formed as a first convex portion 211, and the first convex portion 211 is arranged on the side of the synchronous rotation component 200 along the second direction facing the transmission member 320, and the transmission member 320 includes a first transmission part 322 along the second direction facing the synchronous rotation component 200 and a second transmission part 323 facing the thrust member 310; a second convex portion 3221 is arranged on the side of the first transmission part 322 facing the synchronous rotation component 200; in the unfolded state, the first convex portion 211 and the second convex portion 3221 are staggered along the circumferential direction of the rotating shaft 500, as shown in FIG. Fig.12 In the folded state, the first convex portion 211 abuts against the second convex portion 3221, as shown Fig.13 As shown, the transmission member 320 is driven to slide.

[0068] Optionally, the driving structure 210 is provided with a first convex portion 211, the transmission member 320 includes a first transmission portion 322 facing the synchronous rotation assembly 200, and the first transmission portion 322 is provided with a second convex portion 3221 on the side facing the synchronous rotation assembly 200, and the driving structure 210 rotates with the rotation of the synchronous rotation assembly 200, thereby driving the first convex portion 211 on the driving structure 210 to rotate. In the unfolded state, the first convex portion 211 and the second convex portion 3221 are staggered, and the rotation of the driving structure 210 does not affect the position of the transmission member 320, so that the push member 310 is kept in the second position to avoid affecting the rotation of the synchronous rotation assembly 200. When the synchronous rotating component 200 gradually rotates from the unfolded state to the folded state, the first protrusion 211 rotates accordingly, and the distance between the first protrusion 211 and the second protrusion 3221 gradually approaches until the first protrusion 211 abuts against the second protrusion 3221. The first protrusion 211 of the synchronous rotating component 200 continues to rotate, and pushes the transmission member 320 to slide by pushing the second protrusion 3221.

[0069] Optionally, the transmission member 320 also includes a second transmission part 323 facing the push member 310, and the second transmission part 323 contacts the push member 310. When the transmission member 320 slides relative to the rotating shaft 500, the second transmission part 323 drives the push member 310 to move along the first direction, thereby pushing the push member 310 to the second position.

[0070] In some possible implementations, see Figures 1 to 8 and Figures 14 to 16As shown, the second transmission part 323 of the embodiment of the present application is provided with a push surface 3231a, and the push surface 3231a is tilted in the extension direction of the rotating shaft 500. Optionally, the push surface 3231a may include a first end close to the first transmission part 322 along the second direction and a second end away from the first transmission part 322, and in the direction along the second direction and away from the first transmission part 322, the second end extends inwardly tilted compared to the first end, and the tilt direction of the push surface 3231a is not limited in the embodiment of the present application, and the push member 310 is provided with a mating surface 3111, and the mating surface 3111 is parallel to and abuts against the push surface 3231a.

[0071] Optionally, a push surface 3231a is provided on the second transmission part 323, and a mating surface 3111 is provided on the push member 310, and the mating surface 3111 is in contact with the push surface 3231a, and the mating surface 3111 and the push surface 3231a can slide relative to each other. When the transmission member 320 slides relative to the hinge mechanism, the mating surface 3111 slides relative to the push surface 3231a, so that the transmission member 320 drives the push member 310 to slide. Optionally, the push surface 3231a includes a first end close to the first transmission part 322 along the second direction and a second end away from the first transmission part 322, and the second end extends inwardly inclination compared to the first end. In this way, by tilting the push surface 3231a, the movement of the transmission member 320 along the second direction can be converted into the movement of the push member 310 along the first direction, thereby achieving a transmission effect.

[0072] Optionally, the shape of the push member 310 is not limited in the embodiment of the present application. For example, the projection of the push member 310 on the XY plane may be as follows: Figure 3 The L-shape shown in the figure makes the portion of the push member 310 entering the limiting groove 11, i.e., the limiting portion 313, consistent with the extending direction of the limiting groove 11, to ensure that the limiting function of the push member 310 can be fully exerted. Optionally, the push member 310 can be provided with a bending section 312, such as Fig. 9 , Fig.15 and Fig.16 As shown, a space is provided for the interior structure of the smart terminal to avoid interference between the push member 310 and the interior structure.

[0073] Optionally, the push surface 3231a may be along Figure 4 The direction shown can also be tilted Figure 5 The direction shown is inclined, and the specific inclination angle and inclination direction are not limited in the embodiment of the present application, as long as the push member 310 can be pushed to move along the first direction.

[0074] In some possible implementations, see Figures 1 to 8As shown, the second transmission part 323 of the embodiment of the present application is provided with a transmission groove 3231 penetrating along the third direction, the transmission groove 3231 extends along a direction parallel to the push surface 3231a, the push surface 3231a constitutes a part of the groove wall of the transmission groove 3231, the push member 310 includes a matching part 311, the matching part 311 is inserted into the transmission groove 3231 along the third direction, the matching surface 3111 is suitable for constituting a part of the outer surface of the matching part 311, and the matching part 311 is suitable for sliding relative to the transmission groove 3231.

[0075] Optionally, a transmission groove 3231 is further provided on the second transmission part 323, the push surface 3231a forms part of the groove wall of the transmission groove 3231, the push member 310 has a matching portion 311, the matching surface 3111 forms part of the outer surface of the matching portion 311, the matching portion 311 extends into the transmission groove 3231 so that the matching surface 3111 is slidably connected with the push surface 3231a, and the matching surface 3111 slides relative to the push surface 3231a so that the matching portion 311 slides along the transmission groove 3231. By providing the transmission groove 3231, it can be ensured that the matching surface 3111 and the push surface 3231a are kept in contact, and the sliding path of the push member 310 is further limited, which is conducive to ensuring the support function of the push member 310 for the center frame 10.

[0076] In some possible implementations, see Figures 1 to 6 As shown, the hinge mechanism in the embodiment of the present application further includes a fixing member 400 , which covers the push assembly 300 and is fixedly connected to the base 100 .

[0077] Optionally, the push member 310 is configured to be slidably connected to the base 100. If there is no other fixing structure, the push member 310 may be separated from the installation space 110 along the third direction. Therefore, a fixing member 400 is provided, and the fixing member 400 covers the push assembly 300, thereby preventing the push member 310 from falling off and improving the stability of the push member 310. Optionally, a sliding groove (not shown in the figure) extending along the first direction may be provided on the side of the fixing member 400 facing the push member 310. The sliding groove and the push member 310 are slidably matched to further limit the sliding path of the push member 310 and provide a certain sliding space. Excessive friction between the fixing member 400 and the push member 310 affects the sliding of the push member 310. The specific structure of the fixing member 400 is not limited in the embodiment of the present application.

[0078] See also Figure 1 , Figure 3 and Fig.11 As shown, an embodiment of the present application further provides a smart terminal, comprising any hinge mechanism in the above embodiments.

[0079] Optionally, the smart terminal also includes a middle frame 10 and a folding screen 20. There may be two middle frames 10, which are respectively arranged on both sides of the hinge mechanism and are respectively connected to two synchronous rotating components 200; the folding screen 20 includes a folding area corresponding to the middle frame 10, and each folding area is connected to the corresponding middle frame 10.

[0080] Optionally, the structure and working principle of the hinge mechanism are described in detail in the above embodiments and will not be described in detail here.

[0081] Optionally, the smart terminal includes the above-mentioned hinge mechanism, two middle frames 10 and a folding screen 20, the folding screen 20 includes two symmetrically arranged folding areas, the middle frame 10 is connected to the folding areas correspondingly, the hinge mechanism is arranged between the two middle frames 10, and the synchronous rotation component 200 of the hinge mechanism is connected to the middle frame 10 correspondingly. In this way, when the folding screen 20 is folded or unfolded, the folding area drives the synchronous rotation component 200 to rotate relative to the base 100 through the middle frame 10, and when the folding screen 20 rotates from the unfolded state to the folded state, the push member 310 on the hinge mechanism cooperates with the middle frame 10 in a limited position, and when the smart terminal falls, the middle frame 10 remains stable under the action of the push member 310, thereby protecting the folding screen 20 and helping to improve the drop resistance of the smart terminal.

[0082] In summary, the hinge mechanism and the smart terminal provided in the embodiment of the present application include a base 100, a synchronous rotation component 200 and a push component 300. The base 100 is provided with a rotating shaft 500 extending along the second direction on two opposite sides along the first direction. The synchronous rotation component 200 includes two synchronous rotation components 200, and the synchronous rotation component 200 is sleeved on the rotating shaft 500. The smart terminal includes the above-mentioned hinge mechanism, two middle frames 10 and a folding screen 20. The folding screen 20 includes two symmetrically arranged folding areas. The middle frame 10 is connected to the folding area correspondingly. The hinge mechanism is arranged between the two middle frames 10, and the synchronous rotation component 200 of the hinge mechanism is connected to the middle frame 10 correspondingly. When the folding screen 20 is folded and unfolded, the synchronous rotation component 200 is driven by the middle frame 10 to rotate relative to the base 100. The push assembly 300 includes a push member 310. When the synchronous rotation assembly 200 rotates from the unfolded state to the folded state relative to the base 100, the driving structure 210 drives the push member 310 to slide to the second position, and the push member 310 is limitedly matched with the middle frame 10. In this way, when the smart terminal falls and causes the hinge mechanism to contact the ground first, the push member 310 on the hinge mechanism is limitedly matched with the middle frame 10, thereby preventing the middle frame 10 from moving toward the ground under the action of inertia, which is beneficial to protecting the folding screen 20 from damage and effectively improving the drop resistance of the smart terminal.
