Limited by the installation space of the synchronous swing arm, the radius corresponding to the first cam cannot be increased, the damping force is small, and the electronic device has a poor opening and closing feel. Summary of the invention

[0003] The present application aims to provide a hinge structure and an electronic device, which solves the problem in the related art that the damping force provided by the hinge structure is small, thus affecting the opening and closing feel of the electronic device.

[0004] In order to solve the above technical problems, this application is implemented as follows:

[0005] In the first aspect, an embodiment of the present application proposes a hinge structure, comprising: a rotating shaft; a connecting plate, located on one side of the rotating shaft; a first hinge unit, the first hinge unit comprising: a first virtual swing arm, the first virtual swing arm having a first connecting end and a first bearing, the first connecting end being rotatably connected to the connecting plate, and the first bearing being provided with a first cam; a first connecting member, the first connecting member being slidably connected to the rotating shaft, the first connecting member being located on one side of the first virtual swing arm, the first connecting member being provided with a second cam, and the second cam being engaged with the first cam; a first fixing member, arranged on the rotating shaft, the first fixing member being spaced apart and arranged on a side of the first connecting member away from the first virtual swing arm; a first elastic member, located between the first fixing member and the first connecting member; wherein, when the first virtual swing arm rotates along a preset direction, the first cam and the second cam cooperate to drive the first connecting member to move toward the first fixing member to squeeze the first elastic member.

[0006] In a second aspect, an embodiment of the present application provides an electronic device, comprising: at least one hinge structure in the first aspect.

[0007] In an embodiment of the present application, the hinge structure includes a rotating shaft, a connecting plate and a first hinge unit. The connecting plate is located on one side of the rotating shaft.

[0008] The first hinge unit includes a first virtual swing arm, a first connecting member, a first fixing member and a first elastic member.

[0009] The first fixing member is disposed on the rotating shaft. Specifically, the first fixing member is fixedly connected to the rotating shaft, and the first fixing member cannot move relative to the rotating shaft.

[0010] The first connecting member is located at one side of the first virtual swing arm, and the first connecting member is slidably connected to the rotating shaft, that is, the first connecting member can reciprocate relative to the rotating shaft along the direction from the first virtual swing arm to the first fixing member.

[0011] The first elastic member is located between the first fixing member and the first connecting member.

[0012] The first virtual swing arm has a first connection end and a first bearing bush, the first connection end is used to be rotatably connected to the connection plate, the first bearing bush is provided with a first cam, the first connection member is provided with a second cam, the first cam cooperates with the second cam, specifically, the first cam and the second cam are meshed.

[0013] The hinge structure is used for electronic equipment. The electronic equipment includes a plurality of frames. A hinge structure is arranged between any two adjacent frames. In the two adjacent frames, each frame is connected to a connecting plate of the hinge structure.

[0014] When the first virtual swing arm rotates in a preset direction, the first cam and the second cam cooperate to drive the first connecting member to move toward the first fixing member, and the distance between the first connecting member and the first fixing member decreases accordingly, so as to squeeze the first elastic member and generate elastic force. In other words, the first cam, the second cam, the first fixing member, the first connecting member and the first elastic member cooperate to generate rotation damping, thereby satisfying the user's hand feeling experience and realizing the hovering function of the electronic device.

[0015] The present application reasonably sets the structure of the first hinge unit, sets a first cam at the first bearing of the first virtual swing arm, and uses the first cam to cooperate with the second cam on the first connecting member to achieve the purpose of squeezing the first elastic member. The present application sets the first cam on the first bearing, which can provide a larger working space for the first cam compared to setting a cam on the synchronous swing arm in the related art. In this way, the cam radius of the first cam can be greatly increased, thereby achieving the purpose of increasing the damping force, which is conducive to improving the feel when opening and closing the electronic device, and improving the performance and market competitiveness of the electronic device.

[0016] At the same time, the present application arranges a first cam on the first bearing. For the first cam, in the thickness direction of the electronic device, only space needs to be allocated to the first bearing of the first virtual swing arm. The cam is arranged on the synchronous swing arm in the related technology. In the thickness direction of the electronic device, not only space needs to be allocated to the cam, but also space needs to be allocated to the synchronous gear meshing between the two synchronous swing arms, so the thickness of the whole machine will be increased.

[0033] The following is combined with Figures 1 to 7 The hinge structure 10 and the electronic device 40 provided in the embodiments of the present application are described.

[0034] like Figure 1 , Figure 2 and Figure 4As shown, according to some embodiments of the present application, the hinge structure 10 includes: a rotating shaft 110; a connecting plate 120, which is located on one side of the rotating shaft 110; a first hinge unit 200, which includes: a first virtual swing arm 210, the first virtual swing arm 210 has a first connecting end 212 and a first bearing bush 214, the first connecting end 212 is rotatably connected to the connecting plate 120, and the first bearing bush 214 is provided with a first cam 216; a first connecting member 220, the first connecting member 220 is slidably connected to the rotating shaft 110, and the first connecting member 220 is located on one side of the first virtual swing arm 210. On the side, the first connecting member 220 is provided with a second cam 222, and the second cam 222 is engaged with the first cam 216; the first fixing member 230 is arranged on the rotating shaft 110, and the first fixing member 230 is arranged at intervals on the side of the first connecting member 220 away from the first virtual swing arm 210; the first elastic member 240 is located between the first fixing member 230 and the first connecting member 220; wherein, when the first virtual swing arm 210 rotates along a preset direction, the first cam 216 and the second cam 222 cooperate to drive the first connecting member 220 to move toward the first fixing member 230 to squeeze the first elastic member 240.

[0035] In the embodiment of the present application, the hinge structure 10 includes a rotating shaft 110, a connecting plate 120 and a first hinge unit 200. The connecting plate 120 is located at one side of the rotating shaft 110.

[0036] The first hinge unit 200 includes a first virtual swing arm 210 , a first connecting member 220 , a first fixing member 230 and a first elastic member 240 .

[0037] The first fixing member 230 is disposed on the rotating shaft 110 . Specifically, the first fixing member 230 is fixedly connected to the rotating shaft 110 , and the first fixing member 230 cannot move relative to the rotating shaft 110 .

[0038] The first connecting member 220 is located at one side of the first virtual swing arm 210 , and is slidably connected to the rotating shaft 110 , that is, the first connecting member 220 can reciprocate relative to the rotating shaft 110 along the direction from the first virtual swing arm 210 to the first fixing member 230 .

[0039] The first elastic member 240 is located between the first fixing member 230 and the first connecting member 220 .

[0040] The first virtual swing arm 210 has a first connection end 212 and a first bearing bush 214. The first connection end 212 is used to be rotatably connected to the connection plate 120. The first bearing bush 214 is provided with a first cam 216. The first connecting member 220 is provided with a second cam 222. The first cam 216 cooperates with the second cam 222. Specifically, the first cam 216 and the second cam 222 are meshed.

[0041] The hinge structure 10 is used in an electronic device 40 . The electronic device 40 includes a plurality of frames 400 . A hinge structure 10 is provided between any two adjacent frames 400 . In the two adjacent frames 400 , each frame 400 is connected to a connecting plate 120 of the hinge structure 10 .

[0042] When the first virtual swing arm 210 rotates in a preset direction, the first cam 216 and the second cam 222 cooperate to drive the first connecting member 220 to move toward the first fixing member 230, and the distance between the first connecting member 220 and the first fixing member 230 decreases accordingly, so as to squeeze the first elastic member 240, thereby generating elastic force. In other words, the first cam 216, the second cam 222, the first fixing member 230, the first connecting member 220 and the first elastic member 240 cooperate to generate rotation damping, thereby satisfying the user's hand feeling experience and realizing the hovering function of the electronic device 40.

[0043] The present application reasonably sets the structure of the first hinge unit 200, sets the first cam 216 at the first bearing bush 214 of the first virtual swing arm 210, and uses the first cam 216 to cooperate with the second cam 222 on the first connecting member 220 to achieve the purpose of squeezing the first elastic member 240. The present application sets the first cam 216 on the first bearing bush 214, which can provide a larger working space for the first cam 216 compared to setting a cam on the synchronous swing arm in the related art. In this way, the cam radius of the first cam 216 can be greatly increased, thereby achieving the purpose of increasing the damping force, which is conducive to improving the feel when opening and closing the electronic device 40, and improving the performance and market competitiveness of the electronic device 40.

[0044] At the same time, the present application sets a first cam 216 on the first bearing 214. For the first cam 216, in the thickness direction of the electronic device 40, it is only necessary to allocate space to the first bearing 214 of the first virtual swing arm 210. The cam is set on the synchronous swing arm in the related technology. In the thickness direction of the electronic device, it is necessary to allocate space not only to the cam but also to the synchronous gear meshing between the two synchronous swing arms, so the thickness of the whole machine will be increased.

[0045] It is understandable that the two adjacent frames 400 of the electronic device 40 are connected by the hinge structure 10. When the screen of the electronic device 40 is opened, the screen has a rebound force and gravity, and the damping force of the hinge structure 10 can offset the rebound force and gravity of the screen. When the damping force is greater than the rebound force and gravity of the screen, the electronic device 40 can be suspended.

[0046] In some embodiments, Figure 2As shown, a third cam 218 is provided on the side of the first bearing 214 away from the second cam 222, and the first hinge unit 200 also includes: a second connecting member 250, the second connecting member 250 is slidably connected to the rotating shaft 110, the first virtual swing arm 210 is located between the first connecting member 220 and the second connecting member 250, the second connecting member 250 is provided with a fourth cam 252, and the third cam 218 is engaged with the fourth cam 252; a second fixing member 260 is provided on the rotating shaft 110, and the second fixing member 260 is arranged at intervals on the side of the second connecting member 250 away from the first virtual swing arm 210; a second elastic member 270 is located between the second fixing member 260 and the second connecting member 250; wherein, when the first virtual swing arm 210 rotates along a preset direction, the third cam 218 and the fourth cam 252 cooperate to drive the second connecting member 250 to move toward the second fixing member 260 to squeeze the second elastic member 270.

[0047] In this embodiment, the structure of the first hinge unit 200 is further defined.

[0048] The first hinge unit 200 further includes a second connecting member 250 , a second fixing member 260 and a second elastic member 270 .

[0049] The second connecting member 250 is located at one side of the first virtual swing arm 210 , and is slidably connected to the rotating shaft 110 , that is, the second connecting member 250 can reciprocate relative to the rotating shaft 110 along the direction from the first virtual swing arm 210 to the second fixing member 260 .

[0050] The second elastic member 270 is located between the second fixing member 260 and the second connecting member 250 .

[0051] The first virtual swing arm 210 has a first connection end 212 and a first bearing bush 214. The first connection end 212 is used to be rotatably connected to the connection plate 120. The first bearing bush 214 is provided with a third cam 218 on a side away from the second cam 222. The second connecting member 250 is provided with a fourth cam 252. The third cam 218 cooperates with the fourth cam 252. Specifically, the third cam 218 and the fourth cam 252 are meshed.

[0052] When the first virtual swing arm 210 rotates relative to the rotating shaft 110 along a preset direction, the third cam 218 cooperates with the fourth cam 252 to drive the second connecting member 250 to move toward the second fixing member 260, and the distance between the second connecting member 250 and the second fixing member 260 decreases accordingly, so as to squeeze the second elastic member 270, thereby generating elastic force. In other words, the third cam 218, the fourth cam 252, the second fixing member 260, the second connecting member 250 and the second elastic member 270 cooperate to generate rotation damping, thereby satisfying the user's hand feeling experience and realizing the hovering function of the electronic device 40.

[0053] It is understandable that elastic members are provided on both sides of the first virtual swing arm 210, and specifically, the first virtual swing arm 210 is located between the first elastic member 240 and the second elastic member 270. The present application reasonably sets the structure of the first hinge unit 200, and sets a first cam 216 at the first bearing bush 214 of the first virtual swing arm 210, and uses the first cam 216 to cooperate with the second cam 222 on the first connecting member 220, and sets a third cam 218 at the first bearing bush 214 of the first virtual swing arm 210, and uses the third cam 218 to cooperate with the fourth cam 252 on the second connecting member 250, so as to achieve the purpose of squeezing the first elastic member 240 and the second elastic member 270. The present application sets the first cam 216 and the third cam 218 on the first bearing 214. Compared with setting the cam on the synchronous swing arm in the related art, it can provide a larger working space for the first cam 216 and the third cam 218. In this way, the cam radius of the first cam 216 and the third cam 218 can be greatly increased, so as to achieve the purpose of increasing the damping force, which is beneficial to improving the feel when opening and closing the electronic device 40, and improving the use performance and market competitiveness of the electronic device 40.

[0054] It is understandable that in the related art, along the direction perpendicular to the first virtual swing arm to the first connecting member, the synchronous gear is meshed between the two synchronous swing arms, and a cam is provided on the synchronous swing arm. That is to say, along the direction perpendicular to the first virtual swing arm to the first connecting member, layout space is required for installing the synchronous gear. In the present application, the two first virtual swing arms 210 are arranged along the direction perpendicular to the first virtual swing arm 210 to the first connecting member 220. Compared with the structure in the related art, the present application can provide a larger installation space for the first cam 216 and the third cam 218 of the first virtual swing arm 210, so the cam radius of the first cam 216 and the third cam 218 can be greatly increased, and the damping force can be increased.

[0055] At the same time, the present application sets a first cam 216 and a third cam 218 on the first bearing 214. For the first cam 216 and the third cam 218, in the thickness direction of the electronic device 40, only space needs to be allocated to the first bearing 214 of the first virtual swing arm 210. The cam is set on the synchronous swing arm in the related technology. In the thickness direction of the electronic device, not only space needs to be allocated to the cam, but also space needs to be allocated to the synchronous gear meshing between the two synchronous swing arms, so the thickness of the whole machine will be increased.

[0056] In addition, the first virtual swing arm 210 can cooperate with the first connecting member 220, the first fixing member 230, the first elastic member 240, the second connecting member 250, the second fixing member 260 and the second elastic member 270. The first elastic member 240 and the second elastic member 270 are located on both sides of the first virtual swing arm 210. When the first virtual swing arm 210 rotates along a preset direction relative to the rotating shaft 110, the first elastic member 240 and the second elastic member 270 can be compressed at the same time to realize a dual damping mechanism.

[0057] Optionally, the first hinge unit 200 includes two first virtual swing arms 210, a first connecting member 220, a first fixing member 230, a first elastic member 240, a second connecting member 250, a second fixing member 260 and a second elastic member 270. The two first virtual swing arms 210 cooperate to compress the first elastic member 240 and the second elastic member 270 together.

[0058] In the related art, four synchronous swing arms and two elastic members are arranged in the middle of the hinge structure, and the two synchronous swing arms cooperate to compress one elastic member.

[0059] It can be seen from this that compared with the structure in the related art, the present application saves two synchronous swing arms 330, and the space saved by canceling the two synchronous swing arms 330 can be used to install elastic parts, that is, the installation space of the first elastic part 240 and the second elastic part 270 can be increased, and the length of the first elastic part 240 and the second elastic part 270 in the direction from the first virtual swing arm 210 to the first connecting part 220 can be increased, thereby further increasing the damping force of the hinge structure 10.

[0060] At the same time, the structural setting of the present application simplifies the components of the hinge structure 10, which is beneficial to improving the disassembly and assembly efficiency of the hinge structure 10, and can reduce the weight of the hinge structure 10, which is beneficial to reducing the production cost of the product and improving the performance of the product.

[0061] The first bearing bush 214 is a non-enclosed structure, and the first bearing bush 214 is a tile-like structure.

[0062] In some embodiments, Figure 2 As shown, there are two first virtual swing arms 210 and two connecting plates 120 , the rotating shaft 110 is located between the two connecting plates 120 , the first bearings 214 of the two first virtual swing arms 210 are arranged opposite to each other, and the first connecting end 212 of each first virtual swing arm 210 is rotatably connected to a connecting plate 120 .

[0063] In this embodiment, the number and matching structure of the first virtual swing arms 210 and the connecting plates 120 are further limited.

[0064] There are two connecting plates 120 and two first virtual swing arms 210 . The first connecting end 212 of each first virtual swing arm 210 is rotatably connected to one connecting plate 120 .

[0065] The two first virtual swing arms 210 are arranged at intervals along a direction perpendicular to the first virtual swing arms 210 to the first connecting member 220. The first bearings 214 of the two first virtual swing arms 210 are arranged opposite to each other. In other words, the first bearings 214 of the two first virtual swing arms 210 are arranged close to each other, and the first connecting ends 212 of the two first virtual swing arms 210 are arranged far away from each other.

[0066] There are two second cams 222 , and each second cam 222 is engaged with a first cam 216 of the first virtual swing arm 210 .

[0067] The present application reasonably sets the matching structure between the first connecting member 220 and the two first virtual swing arms 210, that is, reasonably sets the matching structure between the first elastic member 240 and the two first virtual swing arms 210, increases the matching area and matching angle between the first virtual swing arm 210 and the first connecting member 220, can squeeze the first elastic member 240 through the first connecting member 220 from multiple directions at the same time, so as to ensure the balance and consistency of the force on the first elastic member 240, can ensure the stability of the generated damping force, is conducive to improving the stability when opening and closing the electronic device 40, and can ensure the effectiveness and stability of the electronic device 40 hovering.

[0068] It can be understood that the two first virtual swing arms 210 , the first fixing member 230 , the first connecting member 220 and the first elastic member 240 cooperate to generate rotation damping.

[0069] In some embodiments, Figure 1 , Figure 3 and Figure 5 As shown, the hinge structure 10 also includes: a second hinge unit 300, which is arranged at intervals on one side of the first hinge unit 200 along the direction from the first connecting member 220 to the first virtual swing arm 210, and the second hinge unit 300 includes: two synchronous swing arms 330, each synchronous swing arm 330 is rotatably connected to a connecting plate 120, and the two synchronous swing arms 330 are arranged at intervals along a direction perpendicular to the first hinge unit 200 to the second hinge unit 300; a synchronous gear 340, which is arranged on the rotating shaft 110, and the synchronous gear 340 is meshed between the two synchronous swing arms 330.

[0070] In this embodiment, the constituent structure of the hinge structure 10 is further defined.

[0071] The hinge structure 10 further includes a second hinge unit 300. Along the direction from the first linking member 220 to the first virtual swing arm 210, the second hinge unit 300 is arranged at one side of the first hinge unit 200. The second hinge unit 300 includes two synchronous swing arms 330 and a synchronous gear 340. The synchronous gear 340 is meshed between the two synchronous swing arms 330.

[0072] Each synchronous swing arm 330 is rotatably connected to a connecting plate 120 to ensure the consistency of the movement of the two synchronous swing arms 330 , and can ensure the consistency of the rotation angles of two adjacent frames 400 of the electronic device 40 .

[0074] In this embodiment, the hinge structure 10 is further defined.

[0075] The hinge structure 10 further includes a second hinge unit 300. That is, the hinge structure 10 includes the first hinge unit 200 and the second hinge unit 300. The second hinge unit 300 is arranged at one side of the first hinge unit 200 along the first linking member 220 to the first virtual swing arm 210.

[0076] The second hinge unit 300 further includes a second virtual swing arm 310 , a third connecting member 350 , a fourth connecting member 320 and a third elastic member 360 .

[0077] The third connecting member 350 is slidably connected to the rotating shaft 110, and the fourth connecting member 320 is slidably connected to the rotating shaft 110. The fourth connecting member 320 is located on the side of the second virtual swing arm 310 facing the first hinge unit 200. The fourth connecting member 320 can slide back and forth relative to the rotating shaft 110 along the direction from the first virtual swing arm 210 to the first fixed member 230.

[0078] The third elastic member 360 is located between the third connecting member 350 and the fourth connecting member 320 .

[0079] The second virtual swing arm 310 has a second connection end 312 and a second bearing bush 314. The second connection end 312 is used to be rotatably connected to the connection plate 120. The second bearing bush 314 is provided with a seventh cam 316. The second bearing bush 314 is provided with a seventh cam 316. The fourth connecting member 320 is provided with an eighth cam 322. The seventh cam 316 cooperates with the eighth cam 322. Specifically, the seventh cam 316 and the eighth cam 322 are meshed.

[0080] When the second virtual swing arm 310 rotates in a preset direction, the seventh cam 316 and the eighth cam 322 cooperate to drive the fourth connecting member 320 to move toward the first hinge unit 200 to squeeze the third elastic member 360, thereby generating elastic force. In other words, the seventh cam 316, the eighth cam 322, the fourth connecting member 320 and the third elastic member 360 cooperate to generate rotation damping, thereby satisfying the user's hand feeling experience and realizing the hovering function of the electronic device 40.

[0081] The present application reasonably arranges the structure of the second hinge unit 300, arranges the seventh cam 316 at the second bearing bush 314 of the second virtual swing arm 310, and uses the seventh cam 316 to cooperate with the eighth cam 322 on the fourth connecting member 320 to achieve the purpose of squeezing the third elastic member 360. The present application arranges the seventh cam 316 at the second bearing bush 314, which can provide a larger working space for the seventh cam 316 compared to the cam arranged on the synchronous swing arm in the related art, so that the cam radius of the seventh cam 316 can be greatly increased, thereby achieving the purpose of increasing the damping force, which is conducive to improving the feel when opening and closing the electronic device 40, and improving the performance and market competitiveness of the electronic device 40.

[0082] At the same time, the present application sets a seventh cam 316 on the second bearing 314. For the seventh cam 316, in the thickness direction of the electronic device 40, it is only necessary to allocate space to the second bearing 314 of the second virtual swing arm 310. The cam is set on the synchronous swing arm in the related technology. In the thickness direction of the electronic device, it is necessary to allocate space not only to the cam but also to the synchronous gear 340 meshing between the two synchronous swing arms 330, so the thickness of the whole machine will be increased.

[0083] The third connecting member 350 is slidably connected to the rotating shaft 110, and the third elastic member 360 is located between the fourth connecting member 320 and the third connecting member 350. Each synchronous swing arm 330 is rotatably connected to a connecting plate 120, and the two synchronous swing arms 330 are both located on the side of the third elastic member 360 facing the first hinge unit 200. The synchronous swing arm 330 is provided with a fifth cam 332, and the third connecting member 350 is provided with two sixth cams 352, and each sixth cam 352 is engaged with a fifth cam 332.

[0084] When the second virtual swing arm 310 rotates along a preset direction, the seventh cam 316 cooperates with the eighth cam 322 , and the fifth cam 332 cooperates with the sixth cam 352 , driving the third connecting member 350 and the fourth connecting member 320 to squeeze the third elastic member 360 at the same time.

[0085] In some embodiments, Figure 6 As shown, the outer peripheral wall of the fifth cam 332 is provided with a tooth surface 3322 , and the tooth surface 3322 is meshed with the synchronous gear 340 .

[0086] In this embodiment, the structure of the synchronous swing arm 330 is further defined.

[0087] The outer peripheral wall of the fifth cam 332 of the synchronous swing arm 330 is provided with a tooth surface 3322, which is used to engage with the synchronous gear 340 to ensure the consistency of the movement of the two synchronous swing arms 330, and can ensure the consistency of the rotation angle of two adjacent frames 400 of the electronic device 40.

[0088] In some embodiments, Figure 1 and Figure 3 As shown, there are two second virtual swing arms 310 , the second bearings 314 of the two second virtual swing arms 310 are arranged opposite to each other, and the second connecting end 312 of each second virtual swing arm 310 is rotatably connected to a connecting plate 120 .

[0089] In this embodiment, the number of the second virtual swing arms 310 is further limited.

[0090] There are two second virtual swing arms 310, and the two second virtual swing arms 310 are arranged along a direction perpendicular to the second virtual swing arm 310 to the fourth connecting member 320. The second bearings 314 of the two second virtual swing arms 310 are arranged opposite to each other. In other words, the second bearings 314 of the two second virtual swing arms 310 are arranged close to each other, and the second connecting ends 312 of the two second virtual swing arms 310 are arranged far away from each other.

[0091] There are two eighth cams 322 , and each eighth cam 322 is engaged with a seventh cam 316 of the second virtual swing arm 310 .

[0092] The present application reasonably sets the matching structure between the fourth connecting member 320 and the two second virtual swing arms 310, that is, reasonably sets the matching structure between the third elastic member 360 and the two second virtual swing arms 310, increases the matching area and matching angle between the second virtual swing arms 310 and the fourth connecting member 320, can squeeze the third elastic member 360 from multiple directions through the fourth connecting member 320 at the same time, so as to ensure the balance and consistency of the force on the third elastic member 360, can ensure the stability of the generated damping force, is conducive to improving the stability when opening and closing the electronic device 40, and can ensure the effectiveness and stability of the electronic device 40 hovering.

[0093] It can be understood that the two second virtual swing arms 310 , the fourth connecting member 320 and the third elastic member 360 cooperate to generate rotation damping.

[0094] In some embodiments, Figure 1 As shown, the number of the second hinge units 300 is two, and the first hinge unit 200 is located between the two second hinge units 300 .

[0095] In this embodiment, the composition of the hinge structure 10 is further defined.

[0096] The hinge structure 10 includes a first hinge unit 200 and two second hinge units 300 , and the first hinge unit 200 is located between the two second hinge units 300 .

[0097] This setting can ensure the matching area and matching angle between the hinge structure 10 and the two adjacent frames 400 of the electronic device 40, can ensure the balance and consistency of the force on the frame 400, can ensure the consistency of the movement of the two adjacent frames 400, is beneficial to improving the stability when opening and closing the electronic device 40, and can ensure the effectiveness and stability of the electronic device 40 hovering.

[0098] In some other embodiments, the number of the second hinge unit 300 is one.

[0099] like Figure 7 As shown, in some further embodiments of the present application, an electronic device 40 is provided, comprising: at least one hinge structure 10 according to any of the above embodiments.

[0100] In the embodiment of the present application, the electronic device 40 includes at least one hinge structure 10 of any of the above embodiments. Since it includes the hinge structure 10 of any of the above embodiments, it has all the beneficial effects of the above hinge structure 10, which will not be described one by one here.

[0101] Optionally, the electronic device 40 can be a mobile terminal such as a mobile phone, a wearable device, a tablet computer, a laptop computer, a mobile computer, an augmented reality device (also known as an AR (Augmented Reality) device), a virtual reality device (also known as a VR (Virtual Reality) device) and a handheld game console, etc.

[0102] In some embodiments, Figure 7 As shown, the electronic device 40 further includes: a plurality of frames 400 , a hinge structure 10 is provided between any two adjacent frames 400 ; and each frame 400 of two adjacent frames 400 is connected to a connecting plate 120 of the hinge structure 10 .

[0103] In this embodiment, the electronic device 40 further includes a plurality of frames 400 . Any two adjacent frames 400 cooperate with one hinge structure 10 .

[0104] Specifically, each frame 400 is connected to a connecting plate 120 of the hinge structure 10 .

[0105] Optionally, when there are two frames 400 , there is one hinge structure 10 . The two frames 400 are rotatably connected via one hinge structure 10 .

[0106] Optionally, when the number of the frames 400 is greater than two, the number of the hinge structures 10 is greater than or equal to two, and any two adjacent frames 400 are rotatably connected via one hinge structure 10 .

[0107] Optionally, the present application reasonably arranges the hinge structure 10 , which can increase the damping force of the hinge structure 10 and improve the opening and closing feel of the electronic device 40 .

[0108] In the related art, a cam of a hinge structure is arranged on a synchronous swing arm.

[0109] In the present application, the hinge structure 10 includes a first hinge unit 200 and a second hinge unit 300. The first hinge unit 200 includes a first virtual swing arm 210, and a first bearing 214 of the first virtual swing arm 210 is provided with a first cam 216 and a third cam 218, and the second hinge unit 300 includes a second virtual swing arm 310, and a second bearing 314 of the second virtual swing arm 310 is provided with a seventh cam 316. That is, by setting the cam on the bearing of the virtual swing arm, the cam radius of the first cam 216, the second cam 222 and the seventh cam 316 can be greatly increased, and greater damping can be achieved through a simple structural form, and ultimately the damping force of the hinge structure 10 is greatly increased while saving costs and installation space.

[0110] The second bearing bush 314 is a non-enclosed structure and a tile-like structure.

[0111] like Figure 1 As shown, the hinge structure 10 of the present application includes a first hinge unit 200 and two second hinge units 300 .

[0112] like Figure 2 As shown, the first hinge unit 200 includes two first virtual swing arms 210, a first connecting member 220, a first fixing member 230, a first elastic member 240, a second connecting member 250, a second fixing member 260 and a second elastic member 270. The first cam 216 and the third cam 218 are arranged on the first bearing bush 214 of the first virtual swing arm 210, and at the same time, the first elastic member 240 and the second elastic member 270 are symmetrically arranged, and the first virtual swing arm 210 symmetrically drives the first elastic member 240 and the second elastic member 270 to work, thereby realizing a double damping mechanism.

[0113] Optionally, the first elastic member 240 includes a spring, a tension spring or a torsion spring, etc., which are not listed here one by one.

[0114] Optionally, the second elastic member 270 includes a spring, a tension spring or a torsion spring, etc., which are not listed here one by one.

[0115] Optionally, the third elastic member 360 includes a spring, a tension spring or a torsion spring, etc., which are not listed here one by one.

[0116] In the hinge structure 10 , the first virtual swing arm 210 and the second virtual swing arm 310 are mainly used to ensure the folding trajectory of the hinge structure 10 .

[0117] In the hinge structure 10, the main function of the synchronous swing arm 330 is to ensure the consistency of the rotation angles of two adjacent frames 400. Figure 3 As shown, a synchronous gear 340 needs to be arranged between the two synchronous swing arms 330 .

[0118] In the hinge structure 10, affected by the axis positions of the synchronous swing arm 330 and the virtual swing arm, the layout widths of the synchronous swing arm 330 and the virtual swing arm are almost equal, but under this width, the synchronous swing arm 330 needs to layout two cam diameters plus two diameters of the synchronous gear 340. The virtual swing arm only needs to layout two bearing diameters.

[0119] Taking the electronic device 40 including a mobile phone as an example, the first virtual swing arm 210 and the second virtual swing arm 310 are collectively referred to as virtual swing arms, the first bearing 214 and the second bearing 314 are collectively referred to as bearings, and the first cam 216, the third cam 218 and the seventh cam 316 are collectively referred to as cams.

[0120] Calculated based on the thickness of the folding phone being in the range of 9mm to 10mm, the cam radius of the virtual swing arm is greater than or equal to 1.5mm and less than or equal to 2mm, and the cam radius of the synchronous swing arm 330 is greater than or equal to 0.8mm and less than or equal to 1.05mm. After the thickness of the whole machine increases, for the cam of the virtual swing arm, in the thickness direction of the electronic device 40, only space needs to be allocated to the first bearing 214 of the first virtual swing arm 210 and the second bearing 314 of the second virtual swing arm 310. In the related art, a cam is set on the synchronous swing arm, and in the thickness direction of the electronic device, space needs to be allocated not only to the cam, but also to the synchronous gear meshing between the two synchronous swing arms, so the thickness of the whole machine will be increased.

[0121] Therefore, if a cam is provided on the bearing of the virtual swing arm, since there is no restriction of the synchronous gear 340, the radius of the cam on the virtual swing arm is about 1.9 times the radius of the cam on the synchronous swing arm.

[0122] Compared with the structure in the related art, the present application saves two synchronous swing arms. The space saved by eliminating the two synchronous swing arms can be used to install elastic parts, that is, the installation space of the first elastic part 240 and the second elastic part 270 can be increased, and the length of the first elastic part 240 and the second elastic part 270 in the direction from the first virtual swing arm 210 to the first connecting part 220 can be increased, thereby increasing the elastic force of the first elastic part 240 and the second elastic part 270 and further increasing the damping force.

[0123] like Figure 1 As shown, there are two second hinge units 300, one second hinge unit 300 corresponds to two groups of damping, the two groups of damping are respectively recorded as damping 1 and damping 2, and the other second hinge unit 300 corresponds to two groups of damping, the two groups of damping are respectively recorded as damping 5 and damping 6. The first hinge unit 200 corresponds to two groups of damping, the two groups of damping are respectively recorded as damping 3 and damping 4.

[0124] In the related art, the middle of the hinge structure has four groups of damping, and either end of the hinge structure has two groups of damping, that is, the hinge structure has eight groups of damping.

[0125] In the related art, in the hinge structure, the elastic force is denoted as F, the cam radius is denoted as r, the damping force is denoted as T, the cut angle at the cam fitting is denoted as ψ, the friction angle is denoted as ρ, the number of damping groups is denoted as N, and T=8×F×r×tan(Ψ+ρ).

[0126] In the present application, the cam radius of the first cam 216, the third cam 218 and the seventh cam 316 is ≈1.9×r, and the cam radius of the synchronous swing arm 330 is r. The length of the first elastic member 240, the second elastic member 270 and the third elastic member 360 increases, and the elastic force corresponding to the first virtual swing arm 210 and the second virtual swing arm 310 is ≈1.3×F. Therefore, in the present application, the damping force corresponding to the first virtual swing arm 210 and the second virtual swing arm 310 is Tvirtual, Tvirtual=(1.9×r×4+2×r)×1.3×F×tan(Ψ+ρ)=12.5×F×r×tan(Ψ+ρ). It can be seen that under the same space, the hinge structure 10 of the present application can provide a damping force equivalent to more than 1.56 times that in the related art while reducing 2 groups of damping.

[0127] The present application designs a cam on the bearing of the virtual swing arm, which can greatly increase the cam radius and effectively increase the damping force.

[0128] The present application can provide a greater damping force while reducing two sets of damping, and the large amount of space saved is also beneficial to the stacking design of the whole machine. For example, the width of the hinge flexible circuit board can be increased.

[0129] The present application can simplify the number of parts of the hinge structure 10 , which is beneficial to improving the efficiency of assembly and disassembly of the hinge structure 10 , reducing the weight of the hinge structure 10 , and reducing the production cost of the hinge structure 10 .

[0130] like Figure 7 As shown, the electronic device 40 includes a fastener 500, and the fastener 500 is used to assemble multiple frames 400 and at least one hinge structure 10. The fastener 500 includes a bolt, a screw or a rivet.
