[0038] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

In addition, the terms "first", "second", etc. are only used to distinguish descriptions and cannot be understood as indicating or implying relative importance.

[0040] In the description of the present disclosure, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "disposed" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, it can be a direct connection, it can be indirectly connected through an intermediate medium, and it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0041] With the development of electronic products, foldable screens are becoming more and more widely used, such as foldable screen mobile phones, foldable screen computers, etc. Foldable screens need hinges to achieve folding and unfolding functions. The hinge structure is crucial, and the performance of the hinge will directly affect the function and experience of the entire machine.

[0042] The hinges in the related art generally adopt a two-stage linkage structure, which has poor operating stability, affects the smoothness of the unfolding, and has limited support for the screen.

[0043] For this reason, Figure 1-Figure 5 As shown, one aspect of the present disclosure provides a hinge, comprising a bracket 1 and at least one folding component.

[0044] The folding component includes two connecting rod groups 21 and two mounting parts 3. The two connecting rod groups 21 correspond to the two mounting parts 3 one by one. The two connecting rod groups 21 and the two mounting parts 3 are symmetrically arranged with the axis of the bracket 1 extending along the first direction as the symmetry axis. The mounting part 3 is used to install the screen.

[0045] Each connecting rod assembly 21 includes a first connecting member 211 and a second connecting member 212. One end of the first connecting member 211 away from the bracket 1 is hinged to the second connecting member 212, and one end of the second connecting member 212 away from the first connecting member 211 is hinged to the mounting portion 3.

[0046] A groove 11 is provided on the bracket 1, and the groove 11 is configured as an arc groove. The first connecting member 211 is formed with a rotating portion 213, and the rotating portion 213 is configured as an arc plate. The rotating portion 213 is rotatably connected to the arc groove. A cover plate 214 is provided at the notch of the groove 11, and the cover plate 214 closes the notch of the groove 11 and limits the rotating portion 213.

[0047] The cover plate 214 can limit the rotating part 213 in the groove 11, and does not affect the rotation of the rotating part 213 in the groove 11, which can facilitate the rotation of the first connecting member 211. In some examples, the cover plate 214 can be connected to the bracket 1 by screws, so that the cover plate 214 closes the notch of the groove 11, and a shielding cover can be provided on the cover plate 214 to shield the screws.

[0048] The two connecting rod groups 21 are symmetrically arranged with the axis of the bracket 1 extending in the first direction as the symmetry axis, and the two mounting parts 3 are symmetrically arranged with the axis of the bracket 1 extending in the first direction as the symmetry axis, so that the two connecting rod groups 21 respectively drive the two mounting parts 3 to move closer to each other or away from each other, thereby realizing the folding and unfolding of the screen. It can be understood that the screen can be a flexible screen, which is connected to the two mounting parts 3.

[0049] The first connecting member 211 can rotate relative to the bracket 1, and the second connecting member 212 can rotate relative to the first connecting member, so that the first connecting member 211, the second connecting member 212 and the mounting portion 3 form a three-stage linkage structure as a whole.

[0050] The hinge includes a folded state and an unfolded state. In the folded state, the two mounting parts 3 are close to each other and can be set at an angle with the bracket 1, and the first connecting member 211 and the second connecting member 212 can be in a straight state. In the unfolded state, the two mounting parts 3 are away from each other, and the first connecting member 211 and the second connecting member 212 can be set at an angle so that the mounting part 3 can be set in the same plane with the bracket 1.

[0051] In the above technical solution, a three-stage linkage structure can be realized by hingedly connecting the first connecting member 211, the second connecting member 212 and the mounting portion 3. The three-stage linkage structure can significantly improve the stability of the movement of the mounting portion 3, thereby improving the stability of the entire hinge, and thus improving the stability of the folding and unfolding of the screen in the electronic device. In addition, through the three-stage linkage structure, the mounting portion 3 can be in the same plane as the bracket 1, thereby increasing the contact area with the screen, providing the installation stability with the screen, and thereby improving the stability of the folding and unfolding of the screen. At the same time, when the hinge is in a folded state, the first connecting member 211 and the second connecting member 212 can be in a straight state, thereby making the two mounting portions 3 directly opposite and parallel, without generating an error angle, thereby making the screen completely fit after being folded, and avoiding the generation of gaps.

[0052] Optionally, in one embodiment of the present disclosure, the bracket 1 is configured as a long strip structure, and the number of folding parts may be two, and the two folding parts are respectively arranged on the bracket 1 at intervals, which can further improve the stability of the folding and unfolding of the screen. In some examples, the two folding parts may be located at both ends of the bracket 1 in the first direction. Of course, in other embodiments, there may be one folding part, and the folding part may be located in the middle of the bracket 1.

[0053] Optionally, in one embodiment of the present disclosure, the folding component also includes a freedom limiting mechanism 22, the freedom limiting mechanism 22 includes a limiting connection member 221 and a synchronization member 222, the first end of the limiting connection member 221 is hinged to the first connection member 211 and / or the second connection member 212, and the second end of the limiting connection member 221 is hinged to the synchronization member 222.

[0054] The bracket 1 is provided with a rotating shaft 44, which is rotatably connected to the bracket 1. The first end of the synchronizer 222 is connected to the rotating shaft 44 so that the synchronizer 222 rotates coaxially with the rotating shaft 44. The end of the synchronizer 222 away from the bracket 1 is connected to the mounting portion 3 to limit the mounting portion 3 from moving along a predetermined trajectory during the hinge folding process. Since the first connecting member 211, the second connecting member 212 and the mounting portion 3 constitute a three-stage linkage mechanism, the rotational degrees of freedom of two or three of them can be limited by the provided degree of freedom limiting mechanism 22, thereby further improving the stability of the motion trajectory of the mounting portion 3, thereby further improving the hinge and the motion stability of the formed screen.

[0055] Optionally, in some examples, the first end of the position-limiting connector 221 may be hinged to the first connector 211, and in other examples, the first end of the position-limiting connector 221 may be hinged to the second connector 212. Of course, in some examples, the first end of the position-limiting connector 221 may be hinged to both the first connector 211 and the second connector 212, which may be specifically configured according to usage requirements and is not excessively limited herein.

[0056] Optionally, in one embodiment of the present disclosure, the first end of the position-limiting connector 221 is hinged to the connection between the first connector 211 and the second connector 212, and the end of the synchronizing member 222 away from the bracket 1 is slidably connected to the mounting portion 3. By such a configuration, the rotational freedom of the first connector 211, the second connector 212 and the mounting portion 3 can be limited, providing stability of the movement trajectory of the mounting portion 3, and the mounting portion 3 can slide relative to the end of the synchronizing member 222 away from the bracket 1, so as to adapt to the change of the first connector 211 and the second connector 212 when the hinge is in the folded state and the unfolded state, so that the synchronizing member 222 maintains a connection relationship with the mounting portion 3, and the restriction on the degree of freedom can be maintained, so that the mounting portion 3 can move stably.

[0057] Optionally, in one embodiment of the present disclosure, the synchronizer 222 is formed with a sliding portion 223, the mounting portion 3 is provided with a slide groove 31, and the sliding portion 223 is slidably connected to the slide groove 31. By being split into two parts, it is possible to facilitate connection with the first connecting member 211 and the second connecting member 212, as well as the mounting portion 3.

[0058] The limiting connector 221 can rotate relative to the first connector 211 and the second connector 212, that is, the limiting connector 221 has two states, and the mounting portion 3 also has two positions relative to the synchronizing member 222, and the sliding portion 223 can slide in the slide groove 31, thereby changing the relative position of the mounting portion 3 and the synchronizing member 222. Optionally, in some examples, the limiting connector 221 can be a plate-like structure or a rod-like structure.

[0059] It is understandable that when the hinge is in the folded state, the limiting connector 221 is attached to the first connector 211, and the sliding portion 223 partially slides out of the sliding groove 31 of the mounting portion 3. When the hinge is in the unfolded state, the limiting connector 221 is not attached to the first connector 211 and is arranged at a certain angle to the first connector 211 and the second connector 212.

[0060] In order to facilitate the connection of the limiting connector 221 with the first connector 211, the second connector 212 and the synchronizing member 222 respectively, so that relative rotation can be achieved, optionally, in one embodiment of the present disclosure, a first connecting through hole is provided at the first end of the limiting connector 221, a first pin 225 is rotatably provided in the first connecting through hole, and the first connector 211 and the second connector 212 are both connected to the first pin 225.

[0061] It can be understood that the first connecting member 211 and the second connecting member 212 are hinged at the same time through the first pin 225, so that the first connecting member 211 and the second connecting member 212 can rotate relative to each other. In some examples, the first connecting through hole and the first pin 225 are arranged along the first direction, and the first end of the limiting connecting member 221 is formed with two first connecting portions arranged at intervals, and the first connecting through hole is opened in the first connecting portion.

[0062] The first connecting member 211 is provided with a third connecting through hole, which is arranged along the first direction, and the first pin shaft 225 is rotatably arranged in the third connecting through hole. Both ends of the first pin shaft 225 pass through the third connecting through hole respectively, and pass through the first connecting through hole to connect with the second connecting member 212. The second connecting member 212 is formed with a second connecting portion, and the second connecting portion is provided with a first connecting hole, and the first pin shaft 225 is rotatably inserted into the first connecting hole.

[0063] A second connecting through hole is formed at the second end of the position-limiting connecting member 221 . A second pin shaft 227 is rotatably disposed in the second connecting through hole. The synchronizing member 222 is connected to the second pin shaft 227 .

[0064] The second connecting through hole and the second pin 227 are arranged along the first direction, and the second end of the position-limiting connecting member 221 is formed with two second connecting portions arranged at intervals, and the second connecting through hole is opened in the second connecting portion. The synchronizer 222 is provided with a fourth connecting through hole, and the second pin 227 passes through the fourth connecting through hole and is rotated and inserted into the second connecting through hole.

[0065] Optionally, in one embodiment of the present disclosure, the first end of the first connecting member 211 is hinged to the bracket 1, the third connecting through hole is arranged at the second end of the first connecting member 211, and the second connecting portion is arranged at the first end of the second connecting member 212, so that the second end of the first connecting member 211 is hinged to the first end of the second connecting member 212, the second end of the second connecting member 212 is provided with a fifth connecting through hole, and a third pin shaft is rotatably arranged in the fifth connecting through hole, the mounting portion 3 is provided with a connecting notch, the second end of the second connecting member 212 is arranged in the connecting notch, and the third pin shaft is hinged to the mounting portion 3.

[0066] Optionally, in one embodiment of the present disclosure, the sliding portion 223 is formed at one end of the synchronizer 222 away from the bracket 1, and the second end of the position-limiting connector 221 is hinged to the middle of the synchronizer 222. By connecting the synchronizer 222 to the rotating shaft 44, the synchronizer 222 can be rotated relative to the bracket 1, so that the synchronizer 222 and the first connector 211 both use the bracket 1 as the rotation coordinate axis, and synchronous movement can be achieved to avoid errors.

[0067] Optionally, in one embodiment of the present disclosure, the number of synchronizers 222 of each degree of freedom limiting mechanism 22 is two, and the two synchronizers 222 are arranged side by side in the first direction on both sides of the limiting connecting member 221. By providing two synchronizers 222, the stability of the mounting portion 3, the first connecting member 211 and the second connecting member 212 during movement can be further improved, thereby improving the stability of the entire hinge.

[0068] Optionally, in another embodiment of the present disclosure, the freedom limiting mechanism 22 includes a connecting rod, a first end of the connecting rod is hinged to the connection between the first connecting member 211 and the second connecting member 212, a long strip-shaped slide groove 31 may be provided on the side of the mounting portion 3, and the second end of the connecting rod is rotatably and slidably connected to the slide groove 31.

[0069] Optionally, in an embodiment of the present disclosure, the hinge further includes at least one angle limiting mechanism 4, and the angle limiting mechanism 4 corresponds to the folding component one by one.

[0070] Each angle limiting mechanism 4 includes a resilient member 41 , a first synchronous gear 42 , two second synchronous gears 43 , two rotating shafts 44 , two cams 45 and two cam plates 46 .

[0071] The two rotating shafts 44 extend along the first direction, are arranged in parallel and are rotatably connected to the bracket 1 , and the two cam plates 46 extend along the second direction and are arranged opposite to each other. The two rotating shafts 44 rotate through the two cam plates 46 respectively.

[0072] The two second synchronous gears 43 and the two cams 45 are respectively sleeved on the two rotating shafts 44 and rotate coaxially. The two second synchronous gears 43 and the two cams 45 are both located between the two cam plates 46 and respectively abut against the two cam plates 46. The first connecting member 211 is located between a second synchronous gear 43 and a cam 45, and the first synchronous gear 42 is meshed with the two second synchronous gears 43.

[0073] The resilient component 41 is connected to the bracket 1 , and is connected to at least one cam plate 46 to drive the cam plate 46 to abut against the second synchronous gear 43 and the cam 45 .

[0074] The angle limiting mechanism 4 is set up to limit the rotation angle of the mounting part 3, so that the mounting part 3 is maintained at a certain angle, thereby achieving temporary fixation of the mounting part 3. When the mounting part 3 needs to be further rotated, a force can be applied to continue the rotation, thereby limiting the rotation direction of the screen so that the screen can be maintained at a certain angle. At the same time, the angle limiting mechanism 4 can produce a damping effect on the rotation of the mounting part 3, thereby improving the rotation stability of the mounting part 3, and thus improving the stability of the screen rotation and avoiding shaking.

[0075] It can be understood that the two rotating shafts 44 are arranged in parallel and are respectively adapted to the freedom limit mechanisms 22 of the two connecting rod groups 21. The second synchronous gears 43 and cams 45 on the two rotating shafts 44 rotate coaxially with the corresponding rotating shafts 44, and the cam plate 46 abuts against the second synchronous gear 43 and the cam 45 under the action of the rebound component 41, thereby generating a damping effect, and the cam plate 46, the second synchronous gear 43 and the cam 45 have convex parts and concave parts, and the mutual cooperation of the convex parts and the concave parts generates a positioning effect, thus forming an angle limit. It should be noted that the second synchronous gear 43 refers to that its side surface has a tooth shape, and the end close to the cam plate 46 has a convex part and a concave part, which can be matched with the cam plate 46.

[0076] In some examples, the rebound component 41 includes a limit plate 412 and at least two springs 411. The limit plate 412 is arranged parallel to the cam plate 46 and also extends along the second direction. The limit plate 412 is arranged opposite to one of the cam plates 46. The spring 411 is arranged between the limit plate 412 and the cam plate 46. A mounting groove of the limit plate 412 is provided on the bracket 1, so that the spring 411 can be compressed. The cam plate 46 is pressed toward the corresponding cam 45 or the second synchronous gear 43 through the rebound force of the spring 411.

[0077] The two mounting parts 3 and the two connecting rod groups 21 of each folding component can achieve synchronous movement by cooperating with the first synchronous gear 42 and the two second synchronous gears 43. In some examples, there may be two first synchronous gears 42, which are meshed with each other and arranged in parallel, and the two first synchronous gears 42 are respectively meshed with the two second synchronous gears 43.
