Technical Field

DETAILED DESCRIPTION

[0068] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0069] The embodiment of the present application provides an electronic device, which can be any device including a rotating shaft, and any electronic device that needs to be flipped can be included in the scope of the embodiment of the present application, such as a laptop, a folding screen mobile phone, a tablet computer with a rotating keyboard, a server, an all-in-one machine, etc.

[0070] The electronic device generally includes a first body, a second body and a hinge mechanism connecting the first body and the second body, and the hinge mechanism enables the first body and the second body to be folded or unfolded relative to each other. As electronic devices are becoming increasingly miniaturized, the thickness of the first body and the second body of the electronic device is becoming thinner and thinner. When the rotating mechanism is folded between the first body and the second body, the screen space formed by the rotating arm of the hinge mechanism changes, and the flexible screen cannot form a preset shape.

[0071] The electronic device provided by the embodiment of the present disclosure includes a first body, a second body and a connecting mechanism; the first body is movably connected to the second body through the connecting mechanism, so that the first body and the second body can be folded or unfolded relative to each other.

[0072] In a specific embodiment, Figure 1 As shown, the connection mechanism includes a connection body 1 and a first rotating arm, and the first rotating arm includes a first sub-rotating arm 21 and a second sub-rotating arm 22; wherein the connection mechanism includes at least a first state. If the connection mechanism is in the first state, the first body and the second body are relatively unfolded. The connection body 1, the first sub-rotating arm 21 and the second sub-rotating arm 22 overlap in the first direction X1. If the connection mechanism is in the first state, the first direction X1 is a direction perpendicular to the bottom surface of the connection body 1, and the connection body 1, the first sub-rotating arm 21 and the second sub-rotating arm 22 overlap in the first direction X1, so that the width of the connection mechanism becomes smaller. After the first body and the second body are respectively connected to the connection mechanism, the distance between the first body and the second body in the width direction can be reduced, so that the first body and the second body can be made thinner.

[0073] In a specific embodiment, Figure 1As shown, the connection mechanism includes a connection body 1 and a first rotating arm, and the first rotating arm includes a first sub-rotating arm 21 and a second sub-rotating arm 22; wherein the connection mechanism includes a first state, if the connection mechanism is in the first state, the connection body 1, the first sub-rotating arm 21 and the second sub-rotating arm 22 overlap in the first direction X1, and when the connection mechanism is in the first state, the first body and the second body are relatively unfolded. Figure 2 As shown, the connection mechanism includes a second state. If the connection mechanism is in the second state, the connection body 1, the first sub-rotation arm 21 and the second sub-rotation arm 22 overlap in the second direction Y1. When the connection mechanism is in the second state, the first body and the second body are relatively folded, and the second direction Y1 is different from the first direction X1. The second direction Y1 is the direction in which the first direction X1 rotates along the rotation center of the first direction X1 in a direction away from the center line of the connection body 1 by a preset angle, such as Figure 2 As shown, the first rotating arm is located on the left side of the connecting body 1, and the second direction Y1 is the direction of the first direction X1 rotating clockwise along the rotation center by a preset angle. If the connecting mechanism is in the first state, the overlapping part of the first sub-rotating arm 21 and the second sub-rotating arm 22 is the first overlapping part; if the connecting mechanism is in the second state, the overlapping part of the first sub-rotating arm 21 and the second sub-rotating arm 22 is the second overlapping part; the first overlapping part is larger than the second overlapping part, that is, in the second state, there is still an overlapping part between the first sub-rotating arm 21, the second sub-rotating arm 22 and the connecting body 1, which can improve the stability of the connecting mechanism.

[0074] In a traditional hinge mechanism, there is only one rotating arm. If the overlap between the rotating arm and the rotating base is to be maintained, the width of the rotating base needs to be increased; if the width of the rotating base is narrowed, when the first body and the second body are folded, the rotating arm of the hinge mechanism will be disengaged from the rotating base. In this embodiment, the first sub-rotating arm 21 and the second sub-rotating arm 22 have a first bonding area, and the second sub-rotating arm 22 and the connecting body 1 have a second bonding area. On the one hand, there is a second overlapping portion between the first sub-rotating arm 21, the second sub-rotating arm 22 and the connecting body 1, so that the first bonding area and the second bonding area are kept large enough to improve the stability of the connecting mechanism; on the other hand, the overall structure of the first rotating arm composed of the first sub-rotating arm 21 and the second sub-rotating arm 22 increases the bonding area with the connecting body 1, thereby improving the stability of the connecting mechanism. Therefore, by adopting the connecting mechanism provided in this embodiment, on the one hand, the width of the connecting mechanism can be made smaller, and on the other hand, the stability of the connecting mechanism can be improved.

[0075] In a specific embodiment, Figure 3As shown, the connecting mechanism includes a connecting body 1, a first rotating arm and a second rotating arm, the first rotating arm includes a first sub-rotating arm 21 and a second sub-rotating arm 22; the second rotating arm is symmetrically arranged with the first rotating arm, and the second rotating arm includes a third sub-rotating arm 23 and a fourth sub-rotating arm 24; wherein, the connecting mechanism includes at least a first state, if the connecting mechanism is in the first state, the connecting body 1, the first sub-rotating arm 21 and the second sub-rotating arm 22 overlap in the first direction X1. The connecting body 1, the third sub-rotating arm 23 and the fourth sub-rotating arm 24 overlap in the third direction X2, the first direction X1 and the third direction X2 are both directions perpendicular to the bottom surface of the connecting body 1, the first direction X1 is parallel to the third direction X2, the connecting body 1, the first sub-rotating arm 21 and the second sub-rotating arm 22 overlap in the first direction X1, the connecting body 1, the third sub-rotating arm 23 and the fourth sub-rotating arm 24 overlap in the third direction X2, which can make the width of the connecting mechanism smaller, and after the first body and the second body are respectively connected to the connecting mechanism, the distance between the first body and the second body in the width direction can be reduced, so that the first body and the second body can be made thinner.

[0076] In one embodiment, in combination Figure 3 and Figure 4 As shown, the connection mechanism includes a connection body 1 and a first rotating arm, the first rotating arm includes a first sub-rotating arm 21 and a second sub-rotating arm 22, and the second rotating arm includes a third sub-rotating arm 23 and a fourth sub-rotating arm 24. The connection mechanism includes a first state, if the connection mechanism is in the first state, the connection body 1, the first sub-rotating arm 21 and the second sub-rotating arm 22 overlap in the first direction X1, and the connection body 1, the third sub-rotating arm 23 and the fourth sub-rotating arm 24 overlap in the third direction X2. If the connection mechanism is in the second state, the connection body 1, the first sub-rotating arm 21 and the second sub-rotating arm 22 overlap in the second direction Y1, and the connection body 1, the third sub-rotating arm 23 and the fourth sub-rotating arm 24 overlap in the fourth direction Y2; the second direction Y1 is the direction of the first direction X1 rotating from the rotation center of the first direction X1 to the direction away from the center line of the connection body 1 by a preset angle, and the fourth direction Y2 is the direction of the third direction X2 rotating from the rotation center of the third direction X2 to the direction away from the center line of the connection body 1 by a preset angle.

[0077] like Figure 4As shown, the first rotating arm is located on the left side of the connecting body 1, the second rotating arm is located on the right side of the connecting body 1, the second direction Y1 is the direction in which the first direction X1 rotates clockwise along the rotation center by a preset angle, and the fourth direction Y2 is the direction in which the third direction X2 rotates counterclockwise by a preset angle. If the connecting mechanism is in the first state, the overlapping part of the first sub-rotating arm 21 and the second sub-rotating arm 22 is the first overlapping part, and the overlapping part of the third sub-rotating arm 23 and the fourth sub-rotating arm 24 is the third part; if the connecting mechanism is in the second state, the overlapping part of the first sub-rotating arm 21 and the second sub-rotating arm 22 is the second overlapping part. The overlapping part of the third sub-rotating arm 23 and the fourth sub-rotating arm 24 is the fourth part; the first overlapping part is larger than the second overlapping part, and the third overlapping part is larger than the fourth overlapping part, that is, when the connecting mechanism is in the second state, there is still an overlapping part between the first sub-rotating arm 21, the second sub-rotating arm 22 and the connecting body 1, and there is still an overlapping part between the third sub-rotating arm 23, the fourth sub-rotating arm 24 and the connecting body 1, which can improve the stability of the connecting mechanism.

[0078] There is a second overlapping portion between the first sub-rotating arm 21, the second sub-rotating arm 22 and the connecting body 1, so that the bonding area between the second sub-rotating arm 22 and the first sub-rotating arm 21 and the connecting body 1 can be kept large enough, and there is a fourth overlapping portion between the third sub-rotating arm 23, the fourth sub-rotating arm 24 and the connecting body 1, so that the bonding area between the fourth sub-rotating arm 24 and the third sub-rotating arm 23 and the connecting body 1 can be kept large enough, thereby improving the stability of the connecting mechanism. The bonding area between the overall structure of the first rotating arm composed of the first sub-rotating arm 21 and the second sub-rotating arm 22 and the connecting body 1 is increased, and the bonding area between the overall structure of the second rotating arm composed of the third sub-rotating arm 23 and the fourth sub-rotating arm 24 and the connecting body 1 is increased, thereby improving the stability of the connecting mechanism. Therefore, by adopting the connecting mechanism provided in this embodiment, on the one hand, the width of the connecting mechanism can be made smaller, and on the other hand, the stability of the connecting mechanism can be improved.

[0079] In a specific embodiment, the connection mechanism includes a second state; the connection mechanism includes: the second rotating arm is symmetrically arranged with the first rotating arm, and the second rotating arm includes a third sub-rotating arm 23 and a fourth sub-rotating arm 24; wherein, if the connection mechanism is in the first state, the first sub-rotating arm 21 is closed with the second sub-rotating arm 22, the third sub-rotating arm 23 is closed with the fourth sub-rotating arm 24, and the surface formed by the first sub-rotating arm 21 and the second sub-rotating arm 22 and the surface formed by the third sub-rotating arm 23 and the fourth sub-rotating arm 24 are coplanar. The surface formed by the first sub-rotating arm 21 and the second sub-rotating arm 22 and the surface formed by the third sub-rotating arm 23 and the fourth sub-rotating arm 24 are coplanar, and a flat supporting surface can be formed. When the flexible screen is set on the first body and the second body, the surface formed by the first sub-rotating arm 21 and the second sub-rotating arm 22 and the surface formed by the third sub-rotating arm 23 and the fourth sub-rotating arm 24 can support the flexible screen and improve the stability of the flexible screen.

[0080] If the connection mechanism is in the second state, the first sub-rotating arm 21 and the second sub-rotating arm 22 are unfolded, the third sub-rotating arm 23 and the fourth sub-rotating arm 24 are unfolded, the first sub-rotating arm 21 is unfolded in a first rotation direction relative to the second sub-rotating arm 22, and the third sub-rotating arm 23 is unfolded in a second rotation direction relative to the fourth sub-rotating arm 24. The first rotation direction is different from the second rotation direction, so that the first rotating arm can be unfolded in a direction away from the center line of the connection body 1 relative to the second rotating arm, and the third rotating arm can be unfolded in a direction away from the center line of the connection body 1 relative to the fourth rotating arm. Figure 4 , the first rotation direction is opposite to the second rotation direction. Figure 4 In the embodiment, when the first sub-rotating arm 21 and the second sub-rotating arm 22 are unfolded, and the third sub-rotating arm 23 and the fourth sub-rotating arm 24 are unfolded, the first rotation direction is clockwise, and the second rotation direction is counterclockwise. After the first sub-rotating arm 21 and the second sub-rotating arm 22 are unfolded, and the third sub-rotating arm 23 and the fourth sub-rotating arm 24 are unfolded, a receiving space is formed between the first sub-rotating arm 21, the second sub-rotating arm 22, the third sub-rotating arm 23 and the fourth sub-rotating arm 24.

[0081] When the flexible screen is disposed on the first body and the second body, the surface formed by the first sub-rotating arm 21 unfolding relative to the second sub-rotating arm 22 and the surface formed by the third sub-rotating arm 23 unfolding relative to the fourth sub-rotating arm 24 can enclose a screen space, and the first sub-rotating arm 21, the second sub-rotating arm 22, the third sub-rotating arm 23 and the fourth sub-rotating arm 24 can support the flexible screen, so that the flexible screen can form a preset shape. Preferably, the surface formed by the first sub-rotating arm 21 unfolding relative to the second sub-rotating arm 22 and the surface formed by the third sub-rotating arm 23 unfolding relative to the fourth sub-rotating arm 24 can enclose a screen space, so that the flexible screen can form a water drop shape.

[0082] In one embodiment, in combination Figure 5 and Fig.11 As shown, the electronic device further includes a first flat plate 31, a second flat plate 32, a first rotating arm and a second rotating arm, wherein the first rotating arm is used to connect the first flat plate 31; the second rotating arm is used to connect the second flat plate 32; wherein, if the connecting mechanism is in the first state, the first flat plate 31, the second flat plate 32, the surface formed by the closing of the first sub-rotating arm 21 and the second sub-rotating arm 22, and the surface formed by the closing of the third sub-rotating arm 23 and the fourth sub-rotating arm 24 are coplanar. The first flat plate 31, the second flat plate 32, the surface formed by the closing of the first sub-rotating arm 21 and the second sub-rotating arm 22, and the surface formed by the closing of the third sub-rotating arm 23 and the fourth sub-rotating arm 24 are coplanar, and a flat supporting surface can be formed. When the flexible screen is disposed on the first body and the second body, the first flat plate 31 and the second flat plate 32 can support the flexible screen, and the first flat plate 31 and the second flat plate 32 cooperate with the connecting mechanism to form a target shape for the supporting surface for supporting the flexible screen. The first flat plate 31, the second flat plate 32, the surface formed by the first sub-rotating arm 21 and the second sub-rotating arm 22, and the surface formed by the third sub-rotating arm 23 and the fourth sub-rotating arm 24 are coplanar and can support the flexible screen, thereby improving the stability of the flexible screen.

[0083] If the connection mechanism is in the second state, the first sub-rotating arm 21 and the second sub-rotating arm 22 are unfolded in the first rotation direction to drive the first flat plate 31, and the third sub-rotating arm 23 and the fourth sub-rotating arm 24 are unfolded in the second rotation direction to drive the second flat plate 32. The first rotation direction is different from the second rotation direction. The first flat plate 31 and the second flat plate 32 are opposite and at a target angle and form a containing space with the connection body 1 of the connection mechanism. That is, the first flat plate 31 and the second flat plate 32 are opposite, the first sub-rotating arm 21 and the second sub-rotating arm 22 are unfolded, the third sub-rotating arm 23 and the fourth sub-rotating arm 24 are unfolded, and the connection body 1 forms a containing space.

[0097] The disclosed embodiment also provides a connection mechanism, which is applied to an electronic device, which may be a mobile terminal, especially a mobile terminal with a foldable screen, such as a mobile phone, a PDA, a laptop computer or a tablet computer.

[0098] The connecting mechanism includes a connecting body 1 and a first rotating arm, the first rotating arm includes a first sub-rotating arm 21 and a second sub-rotating arm 22, wherein the connecting mechanism includes at least a first state, if the connecting mechanism is in the first state, the connecting body 1, the first sub-rotating arm 21 and the second sub-rotating arm 22 overlap in the first direction X1.

[0099] In one embodiment, in combination Figure 5 , Figure 6 and Figure 7 As shown, the connection mechanism includes a fixed arm group, a torque group and a trajectory group.

[0100] The fixed arm group includes a first fixed arm 41 and a second fixed arm 42. The first fixed arm 41 is used for fixed connection with the first body of the electronic device, and the second fixed arm 42 is used for fixed connection with the second body of the electronic device.

[0101] The torque group includes a symmetrically arranged first rotating shaft 61 and a second rotating shaft 62, a synchronization mechanism, a first torque arm 51, and a second torque arm 52. One end of the first torque arm 51 is rotationally connected to the first rotating shaft 61, and the other end of the first torque arm 51 is slidingly matched with the first fixed arm 41. One end of the second torque arm 52 is rotationally connected to the second rotating shaft 62, and the other end of the second torque arm 52 is slidingly matched with the second fixed arm 42. The synchronization component is transmission-connected to the first torque arm 51 and the second torque arm 52, so as to realize synchronous reverse rotation between the first torque arm 51 and the second torque arm 52.

[0102] The track group includes a first rotating arm and a second rotating arm. One end of the first rotating arm is rotationally connected to the connecting body 1, and the other end of the first rotating arm is rotationally connected to the first fixed arm 41. One end of the second rotating arm is rotationally connected to the connecting body 1, and the other end is rotationally connected to the second fixed arm 42.

[0103] When the first body and the second body are relatively folded or unfolded, taking the application of driving force to the first body as an example, the first body is connected to the first fixed arm 41, and the force is transmitted to the first fixed arm 41, and the first fixed arm 41 pushes the first torque arm 51. The first torque arm 51 and the second torque arm 52 can be linked by the synchronization component to achieve synchronous reverse movement of the first torque arm 51 and the second torque arm 52. That is, when one of the first torque arm 51 and the second torque arm 52 is pushed, the other of the first torque arm 51 and the second torque arm 52 will also fold or unfold in the opposite direction.

[0104] When the first fixed arm 41 rotates with the first body and the second fixed arm 42 rotates with the second body, since the first fixed arm 41 is rotationally connected to the first rotating arm and the second fixed arm 42 is rotationally connected to the second rotating arm, the first rotating arm can limit the position of the first fixed arm 41 during the rotation process, and the second rotating arm can limit the position of the second fixed arm 42 during the rotation process. The first torque arm 51 slides with the first fixed arm 41, so that the first fixed arm 41 adapts to the trajectory path of the first rotating arm when it is unfolded or folded, so that the first rotating arm is always in the corresponding position during the unfolding or folding process. The second torque arm 52 slides with the second fixed arm 42, so that the second fixed arm 42 adapts to the unfolding or folding path of the second rotating arm, so that the second fixed arm 42 is always in the corresponding position during the unfolding or folding process.

[0105] In a specific embodiment, the first rotating shaft 61 and the second rotating handle are both installed on the connecting body 1, and the first rotating shaft 61 and the second rotating handle are arranged in parallel. The first body can be rotatably connected to the connecting body 1 through the first rotating shaft 61, and the second body can be rotatably connected to the connecting body 1 through the second rotating shaft 62, so that the first body and the second body can move relative to each other to realize the folding and unfolding of the electronic device.

[0106] In order to enable the first body and the second body to move synchronously relative to each other, the first torque arm 51 is provided with a first gear 511, and the first gear 511 is rotatably connected to the first rotating shaft 61. The second torque arm 52 is provided with a second gear 521, and the second gear 521 is rotatably connected to the second rotating shaft 62. The synchronization component can realize the meshing transmission of the first gear 511 and the second gear 521, so that the first gear 511 and the second gear 521 have opposite directions.

[0107] When the user applies a driving force to the first body, the driving force drives the first body to rotate relative to the connecting body 1, and the first body drives the first torque arm 51 to rotate relative to the connecting body 1, and the first torque arm 51 drives the first gear 511 to rotate relative to the connecting body 1. Through the synchronization component, the first gear 511 drives the second gear 521 to rotate relative to the connecting body 1, and the second gear 521 drives the second drive ratio to rotate relative to the connecting body 1, and finally the second torque arm 52 drives the second body to rotate relative to the connecting body 1, so as to facilitate the operator's use. When the user applies a driving force to the second body, the force transmission direction can be opposite.

[0108] The synchronization component includes a third gear 71 and a fourth gear 72 meshing with each other, the third gear 71 meshes with the first gear 511, and the fourth gear 72 meshes with the second gear 521, so that the first body and the second body can be synchronized in reverse motion. The synchronization component may include an even number of gears meshing in sequence, and the gears on both sides are respectively meshed with the first gear 511 and the second gear 521, so that the first body and the second body can be synchronized in reverse motion.

[0109] In order to enable the electronic device to hover so that the first body and the second body can be relatively fixed within a preset angle, the connecting mechanism also includes a damping component, which includes a moving member 81, an elastic member 82 and a first connecting seat 83. The first rotating shaft 61 and the second rotating shaft 62 are installed on the first connecting seat 83. The moving member 81 can move relative to the first connecting seat 83 along the axial direction of the first rotating shaft 61. The elastic member 82 is arranged between the moving member 81 and the first connecting seat 83. The two ends of the elastic member 82 are respectively abutted against the moving member 81 and the first connecting seat 83. The elastic member 82 can apply an elastic force to the moving member 81 so that the moving member 81 moves in a direction away from the first connecting seat 83 to abut against the first torque arm 51 and the second torque arm 52, thereby preventing the first torque arm 51 and the second torque arm 52 from rotating relative to the connecting body 1, and utilizing the elastic force of the elastic member 82 to make the first body hover relative to the connecting body 1.

[0110] In a specific embodiment, the moving member 81 is provided with a first cam 811, and the moving member 81 is sleeved on the first rotating shaft 61 and the second rotating shaft 62. There are two first cams 811, which are sleeved on the first rotating shaft 61 and the second rotating shaft 62 respectively, so that the first cam 811 can follow the axial movement of the moving member 81 relative to the first rotating shaft 61. Optionally, the first cam 811 is fixedly connected to the moving member 81. The first torque arm 51 and the second torque arm 52 are both provided with a second cam 512, and the first cam 811 and the second cam 512 are abutted against each other, and the first cam 811 and the second cam 512 are provided with abutting inclined surfaces, and the abutting inclined surfaces decompose the interaction force between the first cam 811 and the second cam 512 along the tangential direction of the second cam 512, thereby driving the second cam 512 to rotate, so as to realize the automatic opening and closing of the first body and the second body, that is, to provide torque.

[0111] When the user applies a driving force toward the first body, the driving force drives the first torque arm 51 to rotate relative to the first rotating shaft 61, and the first gear 511 drives the second cam 512 to rotate relative to the first cam 811. The abutting inclined surfaces of the first cam 811 and the second cam 512 interact with each other, so that the first cam 811 drives the moving member 81 to move toward the first connecting seat 83 and causes the elastic member 82 to undergo elastic deformation. When the user's driving force is withdrawn, the elastic member 82 applies an elastic force toward the moving member 81, so that the first cam 811 on the moving member 81 and the second cam 512 on the first torque arm 51 abut against each other, thereby limiting the rotation of the second cam 512, and further limiting the rotation of the first body relative to the connecting body 1. At this time, the first body and the second body are relatively suspended.

[0112] In a specific embodiment, the connecting body 1 is provided with a second connecting seat 84, the second connecting seat 84 is fixedly connected to the connecting body 1, the first rotating shaft 61 and the second rotating shaft 62 are both provided through the second connecting seat 84, the first rotating shaft 61 and the second rotating shaft 62 can both move along the circumferential direction of the first rotating shaft 61, the first gear 511 and the second cam 512 of the first torque arm 51 are respectively provided at both ends of the first connecting seat 83 along the first axial direction, so that the first torque arm 51 cannot move along the axial direction of the first rotating shaft 61. The second gear 521 and the second cam 512 of the second torque arm 52 are respectively provided at both ends of the first connecting seat 83 along the second axial direction, so that the second torque arm 52 cannot move along the axial direction of the second rotating shaft 62.

[0113] The damping assembly further includes a fixing member 85, which is sleeved on the first rotating shaft 61 and the second rotating shaft 62. The first rotating shaft 61 and the second rotating shaft 62 are both provided with a positioning member 86, so that the fixing member 85 cannot move along the axial direction of the first rotating shaft 61. The positioning member 86 can be a buckle or a positioning pin. The fixing member 85 is provided with a third cam 851, and the number of the third cam 851 is two, which are sleeved on the first rotating shaft 61 and the second rotating shaft 62 respectively. Optionally, the third cam 851 is fixedly connected to the fixing member 85.

[0114] The first torque arm 51 and the second torque arm 52 are both provided with a fourth cam 513, the third cam 851 and the fourth cam 513 are abutted against each other, and the third cam 851 and the fourth cam 513 are provided with abutting inclined surfaces, and the abutting inclined surfaces decompose the interaction force between the third cam 851 and the fourth cam 513 along the tangential direction of the fourth cam 513, thereby driving the fourth cam 513 to rotate, so as to realize the automatic opening and closing of the first body and the second body, that is, to provide torque.

[0115] When the user applies a driving force toward the first body, the driving force drives the first torque arm 51 to rotate relative to the first rotating shaft 61, and the first torque arm 51 drives the fourth cam 513 to rotate relative to the third cam 851. The abutting inclined surfaces of the third cam 851 and the fourth cam 513 interact with each other, so that the third cam 851 drives the fixing member 85 and the first rotating shaft 61 and the second rotating shaft 62 to move in a direction away from the first connecting seat 83, and the axial distance between the first connecting seat 83 and the second connecting seat 84 on the first rotating shaft 61 becomes shorter. The moving member 81 compresses the elastic member 82 and causes the elastic member 82 to undergo elastic deformation. When the user's driving force is withdrawn, the elastic member 82 applies an elastic force toward the moving member 81 and the first connecting seat 83, so that the third cam 851 on the fixing member 85 abuts against the fourth cam 513 on the first torque arm 51, thereby limiting the rotation of the fourth cam 513, and further limiting the rotation of the first body relative to the connecting body 1. At this time, the first body and the second body are relatively suspended.

[0116] In one embodiment, when the user applies a driving force toward the first body, the first cam 811 and the second cam 512 interact with each other, and the third cam 851 and the fourth cam 513 interact with each other, and the two groups of cams act simultaneously, which can increase the pressure on the elastic member 82; when the user's driving force is withdrawn, the elastic member 82 applies an elastic force toward the movable member 81, so that the first cam 811 on the movable member 81 and the second cam 512 on the first torque arm 51 abut against each other, thereby limiting the rotation of the second cam 512, and the elastic member 82 applies an elastic force toward the movable member 81 and the first connecting seat 83, so that the third cam 851 on the fixed member 85 and the fourth cam 513 on the first torque arm 51 abut against each other, thereby limiting the rotation of the fourth cam 513, and further limiting the rotation of the first body relative to the connecting body 1, thereby reducing the possibility of shaking of the first body and the second body when they are relatively hovering.

[0117] In some specific embodiments, the first rotating arm includes a first sub-rotating arm 21 and a second sub-rotating arm 22, the second sub-rotating arm 22 is rotatably connected to the first sub-rotating arm 21 and the connecting body 1, respectively, and the first sub-rotating arm 21 is rotatably connected to the first fixed arm 41; the second rotating arm includes a third sub-rotating arm 23 and a fourth sub-rotating arm 24, the fourth sub-rotating arm 24 is rotatably connected to the third sub-rotating arm 23 and the connecting body 1, respectively, and the third sub-rotating arm 23 is rotatably connected to the second fixed arm 42. If the connecting mechanism is in the first state, the connecting body 1, the first sub-rotating arm 21 and the second sub-rotating arm 22 overlap in the first direction X1, and the connecting body 1, the third sub-rotating arm 23 and the fourth sub-rotating arm 24 overlap in the third direction X2, which can make the width of the connecting mechanism smaller. When the connecting mechanism is in the second state, there is still an overlapping portion between the first sub-rotating arm 21, the second sub-rotating arm 22 and the connecting body 1, and there is still an overlapping portion between the third sub-rotating arm 23, the fourth sub-rotating arm 24 and the connecting body 1, which can improve the stability of the connecting mechanism.
