[0058] The utility model will be described below in combination with Figures 1-11The opening and closing control device and the electronic device provided by the utility model embodiment are described in detail through specific embodiments and application scenarios.

[0059] In a first aspect, as shown in Figure 1 , Figure 2 and Figure 3 , the utility model embodiment provides an opening and closing control device 1, which is applied to an electronic device, and the electronic device comprises a first device main body 2 and a second device main body 3 capable of being rotationally connected; wherein the opening and closing control device 1 comprises a moving assembly 11, a lifting piece 12 and a first magnetic attraction assembly 13;

[0060] The moving assembly 11 is configured to be movably arranged on the first device main body 2; the lifting piece 12 is configured to be movably arranged on the first device main body 2 and is in transmission connection with the moving assembly 11, so that the moving assembly 11 drives the lifting piece 12 to move up and down; the first magnetic attraction assembly 13 comprises a first magnetic attraction piece 131 and a second magnetic attraction piece 132 capable of being attracted to each other, the first magnetic attraction piece 131 is arranged on the lifting piece 12, and the second magnetic attraction piece 132 is configured to be arranged on the second device main body;

[0061] The first magnetic attraction piece 131 and the second magnetic attraction piece 132 cooperate to control the connection or separation of the first device main body 2 and the second device main body 3.

[0062] It can be understood that the electronic device can be switched between a folded state and an open state, when the electronic device is in the folded state, the side of the first device main body 2 facing the second device main body 3 is attached to the side of the second device main body 3 facing the first device main body 2, and when the electronic device is in the open state, the side of the first device main body 2 facing the second device main body 3 is separated from the side of the second device main body 3 facing the first device main body 2.

[0063] For the opening and closing control device 1, the moving assembly 11 can be movably arranged on the first device main body 2 along the length direction or the width direction of the first device main body 2, the lifting piece 12 is movably arranged on the first device main body 2 along the thickness direction of the first device main body 2, and the lifting piece 12 can be lifted relative to the first device main body 2 based on the lifting guide structure on the first device main body 2.

[0064] The transmission connection between the moving assembly 11 and the lifting piece 12 can be achieved by using a slope matching structure or a gear and rack transmission assembly, so as to drive the lifting piece 12 to move up and down relative to the first device main body 2 based on the movement of the moving assembly 11, and then drive the first magnetic attraction piece 131 to move close to or away from the second magnetic attraction piece 132 by the lifting piece 12.

[0065] Exemplarily, as shown in Figure 2As shown, the inclined surface matching structure includes a first inclined surface 12201 formed on the lifting piece 12 and a second inclined surface 11210 formed on the moving assembly 11, the first inclined surface 12201 and the second inclined surface 11210 are in contact and can slide relative to each other.

[0066] Exemplarily, the gear and rack transmission assembly includes a transmission gear, a first rack and a second rack, the first rack is connected with the moving assembly 11 and moves under the driving of the moving assembly 11, the first rack and the transmission gear are in meshing arrangement, the transmission gear and the second rack are in meshing arrangement, the second rack extends along the thickness direction of the first device body 2 and is connected with the lifting piece 12.

[0067] For the first magnetic attraction assembly 13, when the electronic device is in the folded state, the first magnetic attraction piece 131 and the second magnetic attraction piece 132 are oppositely arranged, both the first magnetic attraction piece 131 and the second magnetic attraction piece 132 can be permanent magnets, the end of the first magnetic attraction piece 131 facing the second magnetic attraction piece 132 is different in magnetic pole from the end of the second magnetic attraction piece 132 facing the first magnetic attraction piece 131, so that the first magnetic attraction piece 131 and the second magnetic attraction piece 132 can be attracted to each other when the electronic device is in the folded state.

[0068] Both the first magnetic attraction piece 131 and the second magnetic attraction piece 132 can be provided with multiple permanent magnets, the multiple permanent magnets corresponding to the first magnetic attraction piece 131 are oppositely arranged with the multiple permanent magnets corresponding to the second magnetic attraction piece 132.

[0069] Of course, in actual application, when the magnetic attraction force between the first magnetic attraction piece 131 and the second magnetic attraction piece 132 meets the demand, one of the first magnetic attraction piece 131 and the second magnetic attraction piece 132 can be set as a permanent magnet, and the other one of the first magnetic attraction piece 131 and the second magnetic attraction piece 132 can be set as a ferromagnetic member, which can be an iron sheet or a silicon steel sheet, etc.

[0070] The opening and closing control device 1 shown in the utility model, through the configuration mobile assembly 11, lifting piece 12 and first magnetic attraction assembly 13, can drive lifting piece 12 to do lifting movement by controlling the movement of mobile assembly 11, and then first magnetic attraction piece 131 is driven by lifting piece 12 to approach or away from second magnetic attraction piece 132, because first magnetic attraction piece 131 is located in first equipment main body 2, and second magnetic attraction piece 132 is located in second equipment main body, when electronic equipment is in folding state, first magnetic attraction piece 131 can be controlled to approach second magnetic attraction piece 132, to ensure that first equipment main body 2 and second equipment main body 3 are pasted based on the magnetic attraction force between first magnetic attraction piece 131 and second magnetic attraction piece 132, when needing to control electronic equipment in opening state, first magnetic attraction piece 131 can be controlled to away from second magnetic attraction piece 132, so as to conveniently control first equipment main body 2 and second equipment main body 3 are separated, reach the purpose of conveniently controlling first equipment main body 2 and second equipment main body 3 of electronic equipment are pasted or separated.

[0071] In some embodiments, as shown in Figure 2 and Figure 3 The opening and closing control device 1 further comprises: a first elastic member 14, the first elastic member 14 is arranged between the lifting piece 12 and the mobile assembly 11; the lifting piece 12 has a first inclined surface 12201, and the mobile assembly 11 has a second inclined surface 11210, the first inclined surface 12201 and the second inclined surface 11210 are pasted and can realize mutual sliding; wherein the mobile assembly 11 and the first elastic member 14 cooperate to drive the lifting piece 12 to ascend or descend relative to the first equipment main body 2.

[0072] It can be understood that the first elastic member 14 can be a spring, a spring piece or an elastic sleeve, and the first elastic member 14 is abutted between the lifting piece 12 and the mobile assembly 11.

[0073] For the first inclined surface 12201 of the lifting piece 12 and the second inclined surface 11210 of the mobile assembly 11, the first inclined surface 12201 and the second inclined surface 11210 are smooth planes, and the first inclined surface 12201 and the second inclined surface 11210 are arranged at an angle with the lifting direction of the lifting piece 12, and the lifting direction of the lifting piece 12 is perpendicular to the side of the first equipment main body 2 facing the second equipment main body 3.

[0074] Because the lifting piece 12 and the mobile assembly 11 realize sliding cooperation based on the first inclined surface 12201 and the second inclined surface 11210, when the mobile assembly 11 moves in the first direction, the lifting piece 12 descends under the drive of the mobile assembly 11, and the lifting piece 12 drives the first magnetic attraction piece 131 to move away from the second magnetic attraction piece 132, at this time, the first elastic member 14 is compressed and deformed, and is in a compressed state.

[0075] When the moving assembly 11 moves in the second direction (the second direction is opposite to the first direction), the first elastic member 14 will recover the deformed state, and the lifting member 12 will rise under the elastic force of the first elastic member 14, the first magnetic attraction member 131 will be driven by the lifting member 12 to approach the second magnetic attraction member 132, and the moving assembly 11 will always ensure that the first inclined surface 12201 and the second inclined surface 11210 are in close contact during movement, so as to continue to control the lifting member 12 to descend based on the movement of the moving assembly 11 in the first direction next time.

[0076] wherein, Figure 6 It is shown that the first magnetic attraction member 131 is at the upper dead point and is in the state of approaching the second magnetic attraction member 132 under the driving of the lifting member 12; Figure 7 It is shown that the first magnetic attraction member 131 is at the lower dead point and is in the state of moving away from the second magnetic attraction member 132 under the driving of the lifting member 12.

[0077] In some embodiments, as shown in Figure 6 and Figure 7 , the moving assembly 11 is movably arranged in the accommodating cavity 201 of the first device body 2, and the first end of the accommodating cavity 201 is formed with an opening 202; wherein the accommodating cavity 201 can be arranged to extend along the length direction of the first device body 2.

[0078] Further, as shown in Figure 1 , Figure 2 and Figure 3 , the moving assembly 11 comprises a key 111, a horizontal moving frame 112 and a second elastic member 113; the key 111 is movably arranged in the opening 202 and abuts against the first end of the horizontal moving frame 112; the horizontal moving frame 112 is movably arranged in the accommodating cavity 201 and is in transmission connection with the lifting member 12; the second elastic member 113 abuts between the second end of the horizontal moving frame 112 and the second end of the accommodating cavity 201.

[0079] wherein the first elastic member 14 abuts between the lifting member 12 and the horizontal moving frame 112, the lifting member 12 has a first inclined surface 12201, the horizontal moving frame 112 has a second inclined surface 11210, the first inclined surface 12201 and the second inclined surface 11210 are in close contact and can slide with each other.

[0080] In actual application, the button 111 is used for the pressing operation of the operator, when the operator applies the pressing force to the button 111, the button 111 drives the horizontal moving frame 112 to move horizontally towards the side of the second elastic member 113, so that the second elastic member 113 is compressed by the horizontal moving frame 112, the horizontal moving frame 112 and the lifting member 12 are based on the sliding fit between the first inclined surface 12201 and the second inclined surface 11210, so as to drive the lifting member 12 to drive the first magnetic member 131 to descend, and the first elastic member 14 is compressed by the lifting member 12, at this time, the magnetic attraction force between the first magnetic member 131 and the second magnetic member 132 is weakened, and the operator is convenient to separate the first device main body 2 and the second device main body 3.

[0081] When the operator separates from the button 111, the second elastic member 113 drives the horizontal moving frame 112 to move horizontally towards the side of the button 111, at this time, the first elastic member 14 drives the lifting member 12 to drive the first magnetic member 131 to ascend, the magnetic attraction force between the first magnetic member 131 and the second magnetic member 132 is enhanced, which can ensure that the first device main body 2 and the second device main body 3 are attached together.

[0082] In some examples, as shown in Figure 1 and Figure 4 , the second elastic member 113 can be a spring, the second end of the horizontal moving frame 112 is provided with a positioning protrusion, one end of the spring is inserted outside the positioning protrusion and abuts against the second end of the horizontal moving frame 112, and the other end of the spring abuts against the second end of the accommodating cavity 201.

[0083] In some embodiments, as shown in Figure 2 , Figure 4 and Figure 5 , in order to ensure that the horizontal moving frame 112 reliably drives the lifting member 12 to move up and down, the lifting member 12 comprises a mounting seat 121 and a first trigger head 122, the mounting seat 121 is connected with the trigger head, and the first magnetic member 131 is arranged in the mounting seat 121; the horizontal moving frame 112 comprises a through opening 1120, an inner wall of the through opening 1120 is provided with a second trigger head 1121, the first trigger head 122 is inserted into the through opening 1120, the first trigger head 122 has a first inclined surface 12201, and the second trigger head 1121 has a second inclined surface 11210 which is in sliding fit with the first inclined surface 12201.

[0084] Among them, the first elastic member 14 abuts between the mounting seat 121 and the horizontal moving frame 112, and the mounting seat 121 can be lifted relative to the first device main body 2 under the guidance of the lifting guide structure in the accommodating cavity 201.

[0085] In some embodiments, as shown in Figure 4 and Figure 5As shown, the top surface of the first trigger head 122 is provided with a groove 1221, and part of the groove wall of the groove 1221 is formed as a first inclined surface 12201; the second trigger head 1121 is provided at the top of the through 1120, and the second trigger head 1121 is movably provided in the groove 1221 along the moving direction of the transverse frame 112, and a second inclined surface 11210 is formed on the side of the second trigger head 1121 facing the groove 1221.

[0086] It is understandable that, such as Figure 6 As shown, when the electronic device is in the closed state, the second trigger head 1121 is located at the bottom of the groove 1221. At this time, the height of the first magnetic suction member 131 is at the upper stop point, that is, the first magnetic suction member 131 is set close to the second magnetic suction member 132 to ensure that the first device body 2 and the second device body 3 of the electronic device are in contact.

[0087] like Figure 7 As shown, when switching the electronic device from a closed state to an open state, it is necessary to apply pressure to the button 111. The button 111 drives the horizontal moving frame 112 to move laterally toward one side of the second elastic member 113. The horizontal moving frame 112 drives the second trigger head 1121 to move from the bottom of the groove 1221 to the edge of the groove 1221. Since the movement of the second trigger head 1121 relative to the groove 1221 is based on the sliding cooperation between the first inclined surface 12201 and the second inclined surface 11210, the second trigger head 1121 will drive the lifting member 12 to drive the first magnetic suction member 131 to descend, and the first elastic member 14 is compressed by the lifting member 12. At this time, the magnetic attraction between the first magnetic suction member 131 and the second magnetic suction member 132 is weakened, making it easier for the operator to separate the first device body 2 and the second device body 3 of the electronic device.

[0088] In some embodiments, such as Figure 3 , Figure 6 and Figure 7 As shown, in order to facilitate pressing the button 111 and prevent the button 111 from detaching from the opening 202, the button 111 includes a pressing part 1111, a connecting part 1112, and a limiting part 1113; the first ends of the pressing part 1111 and the connecting part 1112 are connected, the second end of the connecting part 1112 abuts against the first end of the transverse frame 112, and the limiting part 1113 is provided at the second end of the connecting part 1112;

[0089] The pressing part 1111 is configured to protrude from the first end of the opening 202, the connecting part 1112 is configured to be movably inserted into the opening 202, and the limiting part 1113 is configured to abut against the second end of the opening 202.

[0090] In the second aspect, such as Figure 8 , Figure 9 and Figure 10As shown, the utility model embodiment further provides an electronic device, include: first device main body 2, second device main body 3, hinge mechanism 4 and the opening and closing control device 1 as described above,

[0091] First device main body 2 and second device main body 3 are rotatably connected by hinge mechanism 4, and the opening and closing control device 1 is arranged between first device main body 2 and second device main body 3.

[0092] It can be understood that the electronic device can be a notebook computer, for example, in the case that the electronic device is a notebook computer, the first device main body 2 is the host of the notebook computer, and the second device main body 3 is the display screen of the notebook computer.

[0093] In some examples, the first device main body 2 includes a first display screen 21, and the second device main body 3 includes a second display screen 31. Optionally, the electronic device can be a double-screen learning machine, and at this time, the first display screen 21 can be an electronic ink screen, and the second display screen 31 can be a high-definition color screen.

[0094] Of course, the electronic device can also be a folding screen mobile phone and other double-screen electronic devices, which are not limited.

[0095] Since the electronic device includes the opening and closing control device 1, the specific structure of the opening and closing control device 1 is referred to the above-mentioned embodiments, the electronic device of the embodiment includes all the technical solutions of the above-mentioned embodiments, and therefore at least has all the beneficial effects obtained by all the technical solutions of the above-mentioned embodiments, which will not be described one by one.

[0096] In some embodiments, as shown in Figure 10 and Figure 11 The electronic device further includes a second magnetic attraction assembly 5, and the second magnetic attraction assembly 5 includes a third magnetic attraction piece 51 and a fourth magnetic attraction piece 52 that can be attracted to each other.

[0099] Based on the arrangement of the third magnetic attraction member 51 and the fourth magnetic attraction member 52, detachable connection between the hinge mechanism 4 and the second device body 3 can be conveniently achieved. Thus, in actual application, if the electronic device needs to use the first device body 2 and the second device body 3 simultaneously, the third magnetic attraction member 51 and the fourth magnetic attraction member 52 can be attracted to each other, and if the first device body 2 and the second device body 3 of the electronic device need to be used separately, the third magnetic attraction member 51 and the fourth magnetic attraction member 52 can be separated.

[0102] In some examples, a plurality of sets of hinge mechanisms 4 can be provided, and the plurality of sets of hinge mechanisms 4 are arranged in sequence along the rotation axis of the second device body 3 relative to the first device body 2.

[0103] In some embodiments, as shown in Figure 10 and Figure 11 , the hinge mechanism 4 comprises a base 41, a rotating shaft assembly 42, a swing arm assembly 43, an elastic member 44 and a damping assembly 45;

[0104] The rotating shaft assembly 42 comprises a first rotating shaft 421 and a second rotating shaft 422, the first rotating shaft 421 and the second rotating shaft 422 are arranged side by side and are respectively rotatably arranged on the base 41, and the first rotating shaft 421 and the second rotating shaft 422 are power-coupled connected;

[0105] The swing arm assembly 43 comprises a first swing arm 431 and a second swing arm 432, the first swing arm 431 is fixedly connected to the first rotating shaft 421 and connected with the first device body 2, and the second swing arm 432 is fixedly connected to the second rotating shaft 422 and connected with the third magnetic attraction member 51;

[0106] The elastic member 44 is arranged between the rotating shaft assembly 42 and the swing arm assembly 43, and the elastic member 44 can drive the first swing arm 431 and the second swing arm 432 to unfold; the damping assembly 45 is arranged between the base 41 and the rotating shaft assembly 42, and the damping assembly 45 can limit the rotation speed of the first rotating shaft 421 and / or the second rotating shaft 422.

[0109] At the same time, the first rotating shaft 421 and the second rotating shaft 422 are in a power-coupled connection state, and when one of the first rotating shaft 421 and the second rotating shaft 422 rotates, it can drive the other one of the first rotating shaft 421 and the second rotating shaft 422 to rotate synchronously.

[0110] In actual application, in order to facilitate the opening and closing of the first device body 2 and the second device body 3, the first rotating shaft 421 and the second rotating shaft 422 are power-coupled and connected through a gear assembly and realize reverse rotation.

[0111] Exemplarily, the gear assembly comprises a first gear, a second gear, a third gear and a fourth gear; the first gear is arranged on the first rotating shaft 421, the fourth gear is arranged on the second rotating shaft 422, the second gear and the third gear are rotatably arranged on the base 41 respectively, and the first gear, the second gear, the third gear and the fourth gear are arranged in meshing sequence.

[0112] The first swing arm 431 and the second swing arm 432 in the swing arm assembly 43 both have a connecting portion 1112 and an extension portion connected thereto, wherein the connecting portion 1112 of the first swing arm 431 can be fixedly connected to the first rotating shaft 421, and the extension portion can be used to connect the first device body 2; the connecting portion 1112 of the second swing arm 432 can be fixedly connected to the second rotating shaft 422, and the extension portion can be used to connect the second device body 3.

[0114] The elastic member 44 can be an elastic structure such as a torsion spring, which is arranged between the rotating shaft assembly 42 and the swing arm assembly 43, and the elastic member 44 can exert an acting force on the first swing arm 431 and the second swing arm 432 to make them open to each other.

[0115] As an implementation manner, in order to realize the connection of the elastic member 44 with the first swing arm 431 and the second swing arm 432, the elastic member 44 can be configured as a double torsion spring, which includes one connecting segment and two spiral parts, one end of the two spiral parts is connected with each other through the connecting segment, and the other end of the two spiral parts is away from each other, and the extension of the first swing arm 431 and the second swing arm 432 is respectively provided with a clamping groove capable of cooperating with the torsion arm of the two spiral parts.

[0116] In the installation, after the first swing arm 431 and the second swing arm 432 are respectively fixedly connected to the first rotating shaft 421 and the second rotating shaft 422, the two spiral parts of the torsion spring can be respectively sleeved on the first rotating shaft 421 and the second rotating shaft 422, and the torsion arms of the two spiral parts are respectively clamped in the clamping grooves of the extensions of the first swing arm 431 and the second swing arm 432, at this time, under the elastic driving of the elastic member 44, the first swing arm 431 and the second swing arm 432 can be mutually unfolded.

[0117] As can be seen from the above, the hinge mechanism 4 shown in the embodiment can be provided in an electronic device with a folding function, when the electronic device is in a folded state, the first swing arm 431 and the second swing arm 432 are simultaneously in a folded state, at this time, the elastic member 44 is compressed. In the process of switching the electronic device from the folded state to the open state, the elastic member 44 is released, and the elastic member 44 can exert an elastic force on the first swing arm 431 and the second swing arm 432 to drive the first swing arm 431 and the second swing arm 432 to unfold, in the process of unfolding the first swing arm 431 and the second swing arm 432, the first rotating shaft 421 and the second rotating shaft 422 follow the first swing arm 431 and the second swing arm 432 to rotate, under the limitation of the damping assembly 45, the first rotating shaft 421 and / or the second rotating shaft 422 will rotate at a relatively slow speed, and the first swing arm 431 and the second swing arm 432 will unfold at a relatively slow speed, thereby making the first device main body 2 and the second device main body 3 of the electronic device open at a relatively slow and uniform speed.

[0119] It can be understood that the damping box 451 can be made of metal material, which can be configured as a box structure, the inside of the damping box 451 is provided with a sealed cavity, and the damping liquid is filled in the sealed cavity, and the damping liquid can be damping grease, for example, the damping grease can be silicon-based damping grease, polyether-based damping grease, etc.

[0120] The damping load 452 can rotate in the damping box 451 under the driving of the first rotating shaft 421 and / or the second rotating shaft 422, and when the damping load 452 rotates in the damping box 451, the damping load 452 can contact the damping liquid and be interfered by the damping liquid, so that the rotation speed of the damping load 452 in the damping box 451 is limited, and the effect of reducing the rotation speed of the first rotating shaft 421 and / or the second rotating shaft 422 is achieved.
