The technical solutions disclosed in the embodiments of the present application are described in detail below with reference to the accompanying drawings.
In order to solve the problem of abrasion of a damping device in a folding electronic device in the related art, embodiments of the present application provide a folding mechanism. As shown in fig. 1 to 8, the folding mechanism of the embodiment of the present application includes a bracket 300 and a rotating assembly 400.
Wherein the bracket 300 is a base member of the folding mechanism, which provides a mounting base for the rotating assembly 400, and the rotating assembly 400 is connected to the bracket 300.
The rotating assembly 400 is a rotating body of the folding mechanism, and the folding mechanism realizes the folding function and the unfolding function through the rotating assembly 400. Specifically, the folding mechanism includes at least two rotating assemblies 400, the rotating assemblies 400 are respectively connected to two opposite sides of the support 300, the rotating assemblies 400 can rotate on the opposite sides of the support 300, the folding function of the folding mechanism can be realized when the rotating assemblies 400 on two sides of the support 300 rotate in opposite directions, and the unfolding function of the folding mechanism can be realized when the rotating assemblies 400 on two sides of the support 300 rotate in opposite directions.
The number of the rotating assemblies 400 is not limited in the embodiments of the present application, for example, the number of the rotating assemblies 400 on one side of the bracket 300 may be one, two (as shown in fig. 1), three, etc., or the number of the rotating assemblies 400 respectively disposed on two sides of the bracket 300 may be different.
In the embodiment of the present application, as shown in fig. 2, the rotating assembly 400 includes a connecting member 410 and a damping device 420, the connecting member 410 is rotatably coupled to the bracket 300, that is, the connecting member 410 and the bracket 300 can rotate relatively, and the rotating assembly 400 is rotated relative to the bracket 300 by the connecting member 410. Meanwhile, in the embodiment of the present application, the damping device 420 provides a damping effect for the rotation action of the connection member 410, and the connection member 410 in the rotating assembly 400 can be suspended at a specific folding angle.
In the embodiment of the present application, as shown in fig. 3, the damping device 420 includes a first magnet 421 and a second magnet 422, one end of the first magnet 421 is fixedly connected to the bracket 300, and the other end of the first magnet 421 can abut against the connecting member 410; the second magnet 422 is attached to the bracket 300.
It should be understood that, in the embodiment of the present application, the fixed end of the first magnet 421 is fixedly connected to the bracket 300, and the bracket 300 is a mounting base of the first magnet 421; after the assembly is completed, the other end of the first magnet 421 can be abutted against the connecting member 410, so that the first magnet 421 is abutted between the bracket 300 and the connecting member 410, at this time, the first magnet 421 exerts an abutting force on the connecting member 410 due to the pressing, and a damping effect (i.e., a frictional resistance) is generated on the rotation action of the connecting member 410, based on the damping effect, the connecting member 410 can hover relative to the bracket 300, and the connecting members 410 on both sides of the bracket 300 are mutually matched to ensure that the folding mechanism hovers at a specific folding angle.
The first magnet 421 is disposed opposite to the second magnet 422, which facilitates the interaction between the two by magnetic force. Of course, the specific positional relationship of the first magnet 421 and the second magnet 422 is not limited in the embodiments of the present application. As shown in fig. 4, the first magnet 421 and the second magnet 422 are arranged in this order in the thickness direction of the folding mechanism, and at this time, the second magnet 422 is located on the side closer to the screen 100 to which the folding mechanism is attached; in another embodiment, the first magnet 421 may be disposed at a side closer to the folding mechanism attachment screen 100 as long as the first magnet 421 and the second magnet 422 satisfy the feature of opposing arrangement.
Meanwhile, at least one of the first and second magnets 421 and 422 is an electromagnetic structure. It should be understood that, in the embodiment of the present application, only the first magnet 421 or the second magnet 422 may be provided as an electromagnetic structure, or both the first magnet 421 and the second magnet 422 may be provided as an electromagnetic structure. Of course, the embodiment of the present application does not limit the specific arrangement scheme of the electromagnetic structural component.
In the embodiment of the present application, when the connecting member 410 rotates, the first magnet 421 and the second magnet 422 are in a repulsive state, so that the other end of the first magnet 421 is separated from the connecting member 410; when the connecting member 410 suspends, the first magnet 421 and the second magnet 422 are attracted to each other, so that the other end of the first magnet 421 abuts against the connecting member 410 to exert a damping effect on the connecting member 410.
It should be understood that, since the other end of the first magnet 421 abuts against the connecting member 410, a damping effect is generated on the rotation of the connecting member 410, and if the folding angle of the folding mechanism is adjusted, the abrasion inside the folding mechanism (mainly including between the first magnet 421 and the connecting member 410) will be undoubtedly caused; in the embodiment of the application, the folding mechanism can realize abrasion-free rotation and damping hovering by adjusting the power-on and power-off states of the electromagnetic structural part.
Specifically, the electromagnetic device is a device which generates electromagnetism when being electrified, so that the magnetic force state of the electromagnetic structural member can be changed by changing the power-on and power-off state of the electromagnetic structural member. In the embodiment where the first magnet 421 is an electromagnetic structure and the second magnet 422 is a permanent magnet structure, when the first magnet 421 is in the power-off state, the iron core (or the core made of other magnetic conductive material) in the first magnet 421 will be magnetized by the second magnet 422, so that a mutual attractive force is generated between the first magnet 421 and the second magnet 422, and at this time, the other end of the first magnet 421 will be limited to be in a state of abutting against the connecting member 410, thereby ensuring that the connecting member 410 can hover. Reference may be made in detail to the accompanying drawings: as shown in fig. 4, which illustrates an embodiment of the folding mechanism hovering in an unfolded state; as shown in fig. 5, which illustrates an embodiment of the folding mechanism hovering in a folded state (when folded at an angle); as shown in fig. 7, which illustrates an embodiment of the folding mechanism hovering in another folded state (when fully collapsed); in the above embodiment, the other end of the first magnet 421 is in contact with the connecting member 410.
When the folding angle of the folding mechanism needs to be adjusted, that is, the connecting member 410 needs to be rotated, the first magnet 421 can be switched to the power-on state, at this time, the first magnet 421 is specifically magnetic (specifically, the magnetic poles of the first magnet 421 and the second magnet 422 need to be configured to be the same), a mutual repulsive force is generated between the first magnet 421 and the second magnet 422, and the other end of the first magnet 421 is displaced under the action of the repulsive force, so that the other end of the first magnet 421 is separated from the connecting member 410; in this case, during the rotation of the connecting member 410, the connecting member 410 is not subjected to the damping action of the other end of the first magnet 421, and the connecting member 410 not only can obtain smoother rotation efficiency, but also can ensure that no abrasion rotation is achieved between the connecting member 410 and the first magnet 421. Referring specifically to fig. 6, fig. 6 shows an embodiment in which the folding mechanism rotates the link 410 in a folded state (folded at an angle), in which the other end of the first magnet 421 is separated from the link 410.
Of course, in the embodiment in which only the first magnet 421 is an electromagnetic structure member, the magnetic poles of the first magnet 421 can be changed by changing the direction of the current flowing through the first magnet 421, and the first magnet 421 and the second magnet 422 can be switched between the repulsive state and the attractive state based on the principle that like magnetic poles repel each other and unlike magnetic poles attract each other.
In the embodiment in which the first magnet 421 and the second magnet 422 are both electromagnetic structures, the first magnet 421 and the second magnet 422 can be switched between the repelling state and the attracting state based on the principle that like magnetic poles repel each other and unlike magnetic poles attract each other; of course, since both the first magnet 421 and the second magnet 422 may be the adjustment objects, more adjustable solutions can be provided.
It should be noted that, because at least one of the first magnet 421 and the second magnet 422 in the embodiment of the present application is an electromagnetic structural member, the magnitude adjustment of the damping effect between the first magnet 421 and the connecting member 410 can be indirectly achieved by adjusting the magnitude of the current passed through the electromagnetic structural member, so that the user can adjust the hand feeling feedback force by self-operation, and the experience feeling of the user can be optimized undoubtedly.
As can be seen from the above description, in the embodiment of the present application, at least one of the first magnet 421 and the second magnet 422 is an electromagnetic structure, and based on the characteristics of the electromagnetic device, the first magnet 421 and the second magnet 422 can be switched between the repulsive state and the attractive state by changing the magnetic state of the electromagnetic structure in the embodiment of the present application.
When the connecting piece 410 is hovered, the first magnet 421 and the second magnet 422 are in an attraction state, and the other end of the first magnet 421 is abutted against the connecting piece 410 under the attraction of the second magnet 422 to exert a damping effect on the connecting piece 410, so that the hand feeling feedback experience of the folding action can be effectively improved; when the connecting member 410 is rotated, the first magnet 421 and the second magnet 422 are in a repulsive state, and the other end of the first magnet 421 is separated from the connecting member 410 under the repulsive force of the second magnet 422, so that the connecting member 410 is rotated again, which can effectively avoid the abrasion inside the folding mechanism, thereby not only improving the rotation smoothness of the connecting member 410, but also prolonging the service life of the folding mechanism.
In order to improve the convenience of operating the folding mechanism, the folding mechanism of the embodiment of the present application may include a controller (not shown in the drawings), and the controller is in communication connection with the electromagnetic structural component and is used for controlling the magnetic state of the electromagnetic structural component.
Particularly, the controller can realize information interaction with electromagnetic structure, and the user can control the cooperation relation between first magnet 421 and the second magnet 422 through the magnetic state of controlling electromagnetic structure, and then makes folding mechanism realize that the damping is hovered and not have the wearing and tearing and rotate, can promote the convenience of controlling folding mechanism undoubtedly like this.
In this application embodiment, the controller may be an independent control unit in the folding mechanism, or in the electronic device where the folding mechanism is located, the controller may be a control module of the electronic device, and the specific type of the controller is not limited in this application embodiment.
In order to further improve the convenience of operating the folding mechanism, the folding mechanism of the embodiment of the present application may further include a detection device (not shown in the drawings), and the detection device is in communication connection with the controller; the detection device is used for detecting the action state information of the connecting piece 410 and feeding back the action state information to the controller, and the controller controls the electromagnetic structural piece according to the action state information.
Specifically, the controller can realize information interaction with the detection device, the detection device can automatically detect the action state information of the connecting piece 410 and feed back the action state information to the controller in real time, that is, the detection device can feed back the folding state of the folding mechanism to the controller, and the controller can correspondingly regulate and control the matching relationship between the first magnet 421 and the second magnet 422 according to the obtained action state information of the connecting piece 410; so set up down, just need not the magnetic state of user manual control electromagnetic structure spare again, can effectively promote folding mechanism's the convenience of controlling undoubtedly like this, also can optimize user's experience and feel.
In the embodiment of the present application, the detection device may be a gyroscope, a hall element, or the like, and the specific type of the detection device is not limited in the embodiment of the present application.
In order to avoid serious mechanical damage between the first magnet 421 and the connecting member 410, the first magnet 421 of the embodiment of the present application may be an elastic structure member. With such a configuration, when the first magnet 421 is pressed between the bracket 300 and the connecting member 410, the first magnet 421 as an elastic member stores energy due to the pressing, and applies a pressing force to the connecting member 410, thereby generating a damping effect on the rotation of the connecting member 410. Therefore, the first magnet 421 with such a structure has an elastic deformation capability, and the first magnet 421 does not have a rigid abutting relationship when abutting against the connecting member 410, thereby avoiding serious mechanical damage between the two.
In the embodiment of the present application, the specific structure type of the first magnet 421 is various, and for example, it may be a compression spring. In another embodiment, as shown in fig. 2, 4 and 8, the first magnet 421 of the embodiment of the present application may be a spring plate, the spring plate includes a connecting section 421a and an abutting section 421c, the connecting section 421a is disposed obliquely with respect to the abutting section 421c, the spring plate is fixedly connected to the bracket 300 through the connecting section 421a, and the spring plate abuts against the connecting member 410 through the abutting section 421 c.
It should be understood that the first magnet 421 of the spring structure can certainly increase the contact surface with the bracket 300 and the connecting piece 410, so as to optimize the connection reliability of the connecting section 421a with the bracket 300 and improve the abutment stability of the abutting section 421c with the connecting piece 410; meanwhile, since the connection segment 421a is disposed obliquely with respect to the abutting segment 421c, when the first magnet 421 is disposed between the bracket 300 and the connection member 410, the first magnet 421 is pressed between the bracket 300 and the connection member 410, and deformation resisting reaction forces generated by rebounding of the connection segment 421a and the abutting segment 421c are both in substantially the same direction, so that a relatively greater damping effect can be applied to the connection member 410, and therefore, the sensitivity of the rebounding characteristic of the first magnet 421 is higher in this layout structure.
Further, as shown in fig. 4 and 8, the connecting segment 421a of the embodiment of the present application may be U-shaped. With such an arrangement, the U-shaped bent pole connecting section is equivalent to the connecting section 421a being folded in half, so that when the first magnet 421 is pressed between the bracket 300 and the connecting member 410, the connecting section 421a will generate two sets of anti-deformation reaction forces, which can further increase the damping effect on the first magnet 421, and therefore, the connecting section 421a of the structure can further improve the sensitivity of the resilience characteristic of the first magnet 421.
In an alternative, as shown in fig. 4, the first magnet 421 of the embodiment of the present application may further include a main body segment 421b, and the connecting segment 421a is connected to the abutting segment 421c through the main body segment 421 b; the main body segment 421b and the second magnet 422 may be oppositely disposed, when the first magnet 421 and the second magnet 422 are in an attraction state, the main body segment 421b abuts against the second magnet 422, and the shapes of the opposite surfaces of the main body segment 421b and the second magnet 422 are matched.
Specifically, with such a configuration, when the first magnet 421 and the second magnet 422 are in an attraction state, the first magnet 421 will deform toward the second magnet 422, and in the embodiment of the present application, the second magnet 422 will abut against the main body segment 421b to limit the position of the first magnet 421, so as to prevent the first magnet 421 from being damaged due to excessive deformation; meanwhile, the second magnet 422 can limit the first magnet 421 through the main body segment 421b, so that the problem that the other end of the first magnet 421 is excessively pressed on the connecting piece 410 due to the fact that the first magnet 421 is excessively deformed and inclined towards the second magnet 422 can be avoided, and the connecting piece 410 is prevented from being pressed and cannot rotate.
Further, the shapes of the opposing faces of the main body segment 421b and the second magnet 422 may be configured to match, in which case the main body segment 421b and the second magnet 422 may achieve a more stable and reliable bearing relationship through surface-to-surface contact.
In order to further optimize the feeling feedback experience during the folding action, as shown in fig. 3 to 5 and 7, the folding mechanism of the embodiment of the present application may include a rotating shaft 500 and a closing coil 600, the rotating shaft 500 is connected to the bracket 300, and the connecting member 410 is rotatably sleeved on the rotating shaft 500; the closing coil 600 is mounted on the connecting member 410, the closing coil 600 can rotate around the rotating shaft 500 along with the rotation of the connecting member 410, the rotating shaft 500 is a permanent magnet structure, and the closing coil 600 is located in the magnetic field generated by the rotating shaft 500.
It is understood that conductors placed in a changing magnetic flux produce an electromotive force based on the principle of electromagnetic induction. In the embodiment of the present application, the connecting member 410 and the rotating shaft 500 can rotate relatively, and the closing coil 600 is located on the connecting member 410, so that when the connecting member 410 rotates, the closing coil 600 also rotates around the rotating shaft 500; since the rotating shaft 500 is a permanent magnetic structure, a magnetic field is generated around the rotating shaft 500, and when the closed coil 600 rotates around the rotating shaft 500, the closed coil 600 performs a motion of cutting a magnetic induction line in the magnetic field, so that an induced current is generated in the closed coil 600.
Based on lenz's law, it can be known that the magnetic field of the induced current always hinders the change of the magnetic flux causing the induced current, that is, the effect of the induced current always counteracts the cause causing the induced current, therefore, the closed coil 600 can receive an ampere force opposite to the moving direction thereof under the action of the magnetic field of the induced current, the ampere force can exert a damping effect on the rotation of the connecting piece 410 to a certain extent, and then the folding mechanism of the embodiment of the application optimizes the hand feeling feedback experience during the folding action.
In order to improve the compact structure of the folding mechanism, as shown in fig. 4, one end of the connecting member 410 of the embodiment of the application, which is sleeved on the rotating shaft 500, is a rotating end, the outer surface of the rotating end may be provided with a first arc surface 411, the surface of the second magnet 422, which faces the connecting member 410, may be provided with a second arc surface 422a, the second arc surface 422a is matched with the first arc surface 411, and the second magnet 422 escapes from the rotating end through the second arc surface 422 a; the other end of the first magnet 421 may abut against the first arc surface 411.
It should be understood that the rotating end of the connecting element 410 is sleeved on the rotating shaft 500, and the rotating end thereof may be specifically provided with a through mating hole, and the connecting element 410 is sleeved on the rotating shaft 500 through the mating hole of the rotating end thereof; because the second arc surface 422a can avoid the rotation end of the connecting piece 410, and just based on the first arc surface 411 and the second arc surface 422a which are matched, the rotation end of the connecting piece 410 and the second magnet 422 can be arranged adjacently, so that the internal structure of the folding mechanism can be improved undoubtedly.
As shown in fig. 4, in the aforementioned embodiment in which the rotating shaft 500 is a permanent magnetic structure, the connecting member 410 of the embodiment of the present application may be provided with a receiving groove 412 matching with the closing coil 600, the closing coil 600 is disposed in the receiving groove 412, and the receiving groove 412 is configured such that after the closing coil 600 is mounted in the receiving groove 412, the closing coil 600 does not protrude out of the outer surface of the connecting member 410.
Specifically, with such a configuration, the closing coil 600 is embedded in the connecting member 410, which undoubtedly makes the distance between the closing coil 600 and the rotating shaft 500 closer, and the electromagnetic induction effect of the closing coil 600 in the magnetic field of the rotating shaft 500 is enhanced, so that the damping effect generated by the closing coil 600 can be smoothly generated and enhanced; meanwhile, because the closed coil 600 of the embodiment of the present application is installed in the accommodating groove 412, the closed coil 600 does not protrude out of the outer surface of the connecting member 410, and under such a structural layout, the interference of the closed coil 600 on the free end of the first magnet 421 can be avoided, and the space occupation of the connecting member 410 during rotation can also be reduced, so that the second magnet 422 and the connecting member 410 can be arranged in the vicinity of each other, so as to improve the structural compactness of the folding mechanism.
