The following describes the technical scheme disclosed in the embodiments of the present application in detail with reference to the accompanying drawings.
In order to solve the abrasion problem of a damping device in a folding electronic device in the related art, an embodiment of the application provides 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 stand 300 is a base member of the folding mechanism, which provides a mounting base for the rotating assembly 400, the rotating assembly 400 being connected to the stand 300.
The rotating assembly 400 is a rotating body of a folding mechanism, which realizes a folding function and an 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 two opposite sides of the support 300, when the rotating assemblies 400 on two sides of the support 300 rotate in opposite directions, the folding function of the folding mechanism can be achieved, and when the rotating assemblies 400 on two sides of the support 300 rotate in opposite directions, the unfolding function of the folding mechanism can be achieved.
The number of the rotating assemblies 400 is not limited, for example, one, two (as shown in fig. 1), three, etc. rotating assemblies 400 on one side of the bracket 300 may be used, or the number of the rotating assemblies 400 on two sides of the bracket 300 may be different.
In this embodiment, as shown in fig. 2, the rotating assembly 400 includes a connecting member 410 and a damping device 420, where the connecting member 410 is in a rotating fit with the bracket 300, that is, the connecting member 410 and the bracket 300 can rotate relatively, and the rotating assembly 400 can rotate relatively with the bracket 300 through the connecting member 410. Meanwhile, in the present embodiment, the damping device 420 provides a damping effect for the rotational motion of the link 410, and the link 410 in the rotational assembly 400 can hover at a specific folding angle.
In this embodiment, 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 with the bracket 300, and the other end of the first magnet 421 can be abutted against the connecting piece 410; the second magnet 422 is connected to the bracket 300.
It should be understood that the fixed end of the first magnet 421 in the embodiment of the present application is fixedly connected to the bracket 300, and the bracket 300 is the installation 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 piece 410, so that the first magnet 421 is abutted against between the bracket 300 and the connecting piece 410, at this time, the first magnet 421 can apply an abutting force to the connecting piece 410 due to compression, so that a damping effect (i.e. friction resistance) is generated on the rotation action of the connecting piece 410, the connecting piece 410 can hover relative to the bracket 300 based on the damping effect, and the connecting pieces 410 located at two sides of the bracket 300 can mutually cooperate to ensure that the folding mechanism hovers at a specific folding angle.
The first magnet 421 is disposed opposite the second magnet 422, which facilitates interaction of the two by magnetic force. Of course, the embodiment of the present application does not limit the specific positional relationship of the first magnet 421 and the second magnet 422. As shown in fig. 4, in the thickness direction of the folding mechanism, the first magnet 421 and the second magnet 422 are sequentially arranged, and at this time, the second magnet 422 is located at a side closer to the folding mechanism connection screen 100; in other embodiments, the first magnet 421 may be disposed on a side closer to the folding mechanism connection screen 100, as long as the first magnet 421 and the second magnet 422 satisfy the oppositely disposed features.
Meanwhile, at least one of the first magnet 421 and the second magnet 422 is an electromagnetic structural member. 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 structural member, or both the first magnet 421 and the second magnet 422 may be provided as electromagnetic structural members. Of course, embodiments of the present application are not limited to a particular arrangement of electromagnetic structures.
In the embodiment of the present application, when the connection 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 connection member 410; when the connection member 410 hovers, the first magnet 421 and the second magnet 422 are in a attracted state, so that the other end of the first magnet 421 abuts against the connection member 410 to exert a damping effect on the connection member 410.
It should be understood that, when 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 when the folding angle of the folding mechanism is adjusted, the inside of the folding mechanism (mainly including between the first magnet 421 and the connecting member 410) is definitely worn; in the embodiment of the application, the folding mechanism can realize abrasion-free rotation and damping hovering by adjusting the on-off state of the electromagnetic structural member.
Specifically, the electromagnetic device is a device which generates electromagnetic force when energized, so that the magnetic force state of the electromagnetic structural member can be changed by changing the on-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 magnetic 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 is limited to be in a state of abutting against the connecting piece 410, so as to ensure that the connecting piece 410 can hover. See, for specific details, the drawings: as shown in fig. 4, which illustrates an embodiment in which the folding mechanism hovers in an unfolded state; as shown in fig. 5, which illustrates an embodiment in which the folding mechanism hovers in a folded state (when folded at an angle); as shown in fig. 7, which illustrates an embodiment in which the folding mechanism hovers in another folded state (when fully folded in half); in the above embodiment, the other ends of the first magnets 421 are all abutted against the connector 410.
When the folding angle of the folding mechanism needs to be adjusted, that is, when the connecting piece 410 needs to be rotated, the first magnet 421 can be switched to an energized state, and at this time, the first magnet 421 is magnetic (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 repulsive force, so that the other end of the first magnet 421 is separated from the connecting piece 410; in this case, during the rotation of the connecting member 410, the connecting member 410 is no longer subject to the damping action of the other end of the first magnet 421, so that the connecting member 410 can achieve smoother rotation efficiency, and ensure that no-wear 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 connection member 410 in a folded state (folded by a certain angle), in which the other end of the first magnet 421 is separated from the connection member 410.
Of course, in the embodiment in which only the first magnet 421 of the first magnet 421 and the second magnet 422 is an electromagnetic structure, the magnetic pole of the first magnet 421 may be changed by changing the direction of the current flowing in the first magnet 421, and the switching between the repulsive state and the attractive state of the first magnet 421 and the second magnet 422 may be realized based on the principle that the same-name magnetic poles repel each other and the different-name magnetic poles attract each other.
In the embodiment where the first magnet 421 and the second magnet 422 are electromagnetic structures, the switching between the repulsive state and the attractive state of the first magnet 421 and the second magnet 422 can be realized based on the principle that the like-name magnetic poles repel and the like-name magnetic poles attract; of course, since both the first magnet 421 and the second magnet 422 can be adjustment objects, more adjustment schemes can be provided.
It should be noted that, since at least one of the first magnet 421 and the second magnet 422 in the embodiment of the present application is an electromagnetic structure, the damping effect between the first magnet 421 and the connecting piece 410 can be indirectly adjusted by adjusting the current flowing in the electromagnetic structure, so that the user can operate and adjust the feedback force of the hand feeling by himself, and the experience of the user can be optimized.
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 can be in a suction state, and the other end of the first magnet 421 is abutted against the connecting piece 410 under the action of the suction force of the second magnet 422 so as to apply a damping effect to the connecting piece 410, so that the hand feeling feedback experience of the folding action can be effectively improved; when the connecting piece 410 is rotated, the first magnet 421 and the second magnet 422 are in a repulsive state, the other end of the first magnet 421 is separated from the connecting piece 410 under the repulsive force of the second magnet 422, and the rotating of the connecting piece 410 can certainly avoid the abrasion inside the folding mechanism, so that the rotating smoothness of the connecting piece 410 can be improved, and the service life of the folding mechanism can be prolonged.
In order to improve the control convenience of the folding mechanism, the folding mechanism of the embodiment of the application may include a controller (not shown in the drawing), where the controller is in communication connection with the electromagnetic structural member, and the controller is used to control the magnetic state of the electromagnetic structural member.
Specifically, the controller and the electromagnetic structure can realize information interaction, and a user can control the matching relationship between the first magnet 421 and the second magnet 422 by controlling the magnetic state of the electromagnetic structure, so that the folding mechanism realizes damping hovering and abrasion-free rotation, and the control convenience of the folding mechanism can be improved undoubtedly.
In this embodiment of the present application, the controller may be an independent control unit in the folding mechanism, or in an 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 embodiment of the present application.
In order to further improve the convenience of controlling the folding mechanism, the folding mechanism of the embodiment of the application may further include a detection device (not shown in the drawing), where the detection device is communicatively connected to the controller; the detecting 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 part 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 coordination relationship between the first magnet 421 and the second magnet 422 according to the acquired action state information of the connecting piece 410; under the setting, just need not the magnetic state of user manual control electromagnetic structure again, can clearly promote folding mechanism's control convenience 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 embodiment of the present application does not limit a specific type of the detection device.
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 structural member. With this arrangement, when the first magnet 421 is pressed between the bracket 300 and the connecting member 410, the first magnet 421 acts as an elastic member to store energy due to the pressing, and applies a pressing force to the connecting member 410, thereby damping the rotation of the connecting member 410. Therefore, the first magnet 421 with such a structure has elastic deformation capability, and the first magnet 421 will not have rigid contact relationship when contacting the connecting piece 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, for example, it may be a compression spring. In another embodiment, as shown in fig. 2, 4 and 8, the first magnet 421 in this embodiment may be a spring, where the spring includes a connecting section 421a and an abutting section 421c that are connected, the connecting section 421a is obliquely disposed with respect to the abutting section 421c, the spring is fixedly connected with the bracket 300 through the connecting section 421a, and the spring abuts against the connecting piece 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 between the first magnet and the bracket 300 and the connecting piece 410, so that the connection reliability between the connecting section 421a and the bracket 300 can be optimized, and the abutting stability between the abutting section 421c and the connecting piece 410 can be improved; meanwhile, since the connection section 421a is disposed obliquely with respect to the abutment section 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 the deformation-resistant reaction forces generated by the rebound of the connection section 421a and the abutment section 421c are all in substantially the same direction, so that a relatively larger damping effect can be applied to the connection member 410, and therefore, the sensitivity of the rebound characteristic of the first magnet 421 is higher with this layout structure.
Further, as shown in fig. 4 and 8, the connection section 421a in the embodiment of the present application may be U-shaped and bent. Under such setting, the U type is bent the utmost point section and is equivalent to making the linkage segment 421a realize the fifty percent discount, just so makes first magnet 421 when being pressed between support 300 and connecting piece 410, linkage segment 421a can produce two sets of anti-deformation reaction force, can further increase the damping effect that first magnet 421 received like this, therefore, the sensitivity of the resilience characteristic of first magnet 421 can further be promoted to linkage segment 421a of this kind of structure.
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 section 421b, and the connection section 421a is connected to the abutment section 421c through the main body section 421 b; the main body section 421b and the second magnet 422 may be disposed opposite to each other, and when the first magnet 421 and the second magnet 422 are attracted to each other, the main body section 421b abuts against the second magnet 422, and the shapes of the opposite surfaces of the main body section 421b and the second magnet 422 are matched.
Specifically, when the first magnet 421 and the second magnet 422 are in the attracted state, the first magnet 421 will deform toward the second magnet 422, and in this embodiment, the second magnet 422 abuts against the main body section 421b to limit the first magnet 421, so as to avoid damage of the first magnet 421 due to excessive deformation; meanwhile, the second magnet 422 can limit the first magnet 421 through the main body section 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 excessively deforms and inclines 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 body segment 421b and the second magnet 422 may be configured to mate, in which case the body segment 421b and the second magnet 422 may achieve a more stable and reliable bearing relationship through face-to-face contact.
In order to further optimize the feel 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, where the rotating shaft 500 is connected to the bracket 300, and the connecting piece 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 magnetic structure, and the closing coil 600 is positioned in a magnetic field generated by the rotating shaft 500.
It will be appreciated that conductors placed in varying magnetic flux will generate 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 the closing coil 600 also rotates around the rotating shaft 500 when the connecting member 410 rotates; since the rotating shaft 500 is a permanent magnetic structure, a magnetic field is generated around the rotating shaft 500, and when the closing coil 600 rotates around the rotating shaft 500, it performs a motion of cutting a magnetic induction line in the magnetic field, so that an induced current is generated in the closing coil 600.
Based on lenz's law, the magnetic field of the induced current always blocks the change of the magnetic flux of the induced current, that is, the effect of the induced current always resists the cause of the induced current, so that the closing coil 600 receives an ampere force opposite to the moving direction of the closing coil under the action of the magnetic field of the induced current, and the ampere force can exert a damping effect on the rotation of the connecting piece 410 to a certain extent, so that the folding mechanism in the embodiment of the application optimizes the feel feedback experience during the folding action.
In order to promote the compact structure of the folding mechanism, as shown in fig. 4, one end of the rotating shaft 500 sleeved with the connecting piece 410 in the embodiment of the present application 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 facing the connecting piece 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 dodges 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 piece 410 is sleeved on the rotating shaft 500, the rotating end thereof can be specifically provided with a through matching hole, and the connecting piece 410 is sleeved on the rotating shaft 500 through the matching hole of the rotating end thereof; because the second arc surface 422a can avoid the rotating end of the connecting piece 410, and it is based on the first arc surface 411 and the second arc surface 422a that are matched, the rotating end of the connecting piece 410 and the second magnet 422 can be disposed adjacently, so that the compact structure inside the folding mechanism can be improved.
As shown in fig. 4, in the foregoing embodiment where the rotating shaft 500 is a permanent magnetic structure, the connecting piece 410 of the embodiment of the present application may be provided with a receiving groove 412 matched 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 the closing coil 600 does not protrude out of the outer surface of the connecting piece 410 after the closing coil 600 is mounted in the receiving groove 412.
Specifically, with this arrangement, the closing coil 600 is embedded in the connecting piece 410, which certainly 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, since the closed coil 600 of the embodiment of the application is mounted in the accommodating groove 412, the closed coil 600 does not protrude out of the outer surface of the connecting piece 410, under such a structural layout, interference obstruction of the closed coil 600 on the free end of the first magnet 421 can be avoided, space occupation of the connecting piece 410 during rotation can be reduced, and further the second magnet 422 and the connecting piece 410 can be adjacently arranged, so that structural compactness of the folding mechanism is improved.
As shown in fig. 4 to 7, the embodiment of the present application further provides an electronic device, which includes the flexible screen 100, the first housing, the second housing, and the folding mechanism mentioned in any of the foregoing schemes, so that the electronic device has the beneficial effects of any of the foregoing schemes, and will not be repeated again.
The first shell and the second shell are basic components of the electronic equipment, provide mounting bases for other components of the electronic equipment, and also play a certain protection function. Specifically, the first and second housings are respectively connected to the rotation assemblies 400 at both sides of the bracket 300 and are rotatable with the rotation assemblies 400; the flexible screen 100 is connected to the first housing and the second housing, and the flexible screen 100 is switchable between a folded state and an unfolded state when the first housing and the second housing are rotated relative to each other.
It should be appreciated that both the first housing and the second housing are rotated by the connector 410; based on the folding mechanism, damped hover and wear-free rotation between the first and second housings may be achieved, thus enabling a good feel feedback experience when the flexible screen 100 is switched between the folded and unfolded state.
In order to facilitate the rotation of the connector 410 in the assembly 400 to support the flexible screen 100, the electronic device according to the embodiment of the present application may further include an adapter board 200, where the adapter board 200 is attached to the flexible screen 100, and one end of the connector 410 facing away from the bracket 300 is in rotational fit with the adapter board 200. With the arrangement, as the adapter plate 200 provides a larger bearing area, the folding mechanism can stably support the flexible screen 100 through the adapter plate 200 and can smoothly drive the flexible screen 100 to fold; meanwhile, the connecting piece 410 and the adapter plate 200 are in a running fit relationship, so that when the folding mechanism folds, a certain activity allowance can exist at the connecting position of the connecting piece 410 and the adapter plate 200, and further damage to the flexible screen due to the fact that the connecting piece 410 and the adapter plate are in a pure rigid connection relationship is avoided.
As shown in fig. 4, which illustrates the electronic device with the flexible screen 100 in an expanded state; as shown in fig. 5, which illustrates the electronic device with the flexible screen 100 in a folded state (folded at an angle); as shown in fig. 7, which shows the electronic device with the folding mechanism in another folded state (fully folded in half).
