Detailed Description

For the purposes, technical solutions and advantages of the present application, the technical solutions of the present application will be clearly and completely described below with reference to specific embodiments of the present application and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

The technical solutions disclosed in the embodiments of the present application are described in detail below by specific embodiments with reference to the accompanying drawings.

As shown in fig. 1 to 18, an embodiment of the present application discloses an electronic device including a flexible screen and a plurality of hinge mechanisms.

The plurality of hinge mechanisms can act as supports for the flexible screen 300. The flexible screen 300 includes a plurality of first regions 310 and a plurality of second regions 320, the plurality of first regions 310 are in one-to-one correspondence with the plurality of hinge mechanisms, and two adjacent first regions 310 are connected through the second regions 320. Since the plurality of first regions 310 correspond one-to-one to the plurality of hinge mechanisms, the second regions 320 correspond to spaces between two adjacent hinge mechanisms.

The plurality of first areas 310 comprise a first sub-area 311 and a plurality of second sub-areas 312, and the plurality of second sub-areas 312 are symmetrically arranged with the first sub-area 311 as a symmetry center; the hinge mechanisms are arranged in a row, the hinge mechanisms located in the same row comprise a central hinge mechanism and a plurality of side hinge mechanisms, the central hinge mechanism is used for supporting the first subarea 311, so that the electronic equipment can be folded in half by taking the first subarea 311 as the center, the central hinge mechanism corresponds to the first subarea 311, the side hinge mechanisms support the second subareas 312 in a one-to-one correspondence manner, and therefore two adjacent second subareas 312 can be folded by taking the side hinge mechanisms as folding centers.

The electronic device disclosed in the embodiment of the application is improved by the related technology, so that the electronic device comprises a plurality of hinge mechanisms, the flexible screen 300 can be supported by the hinge mechanisms, and further the flexible screen 300 can be folded or unfolded along with the hinge mechanisms between corresponding areas. During a specific folding process, the plurality of second sub-regions 312 may be symmetrically arranged about the first sub-region 311 by a central hinge mechanism. While the second plurality of sub-regions 312 may be folded or unfolded by a side-by-side hinge mechanism. Obviously, the electronic equipment disclosed by the embodiment of the application can be folded to form various shapes, so that the electronic equipment has better folding performance.

Of course, it should be noted that the electronic device generally includes a device housing, and in the case of a folding electronic device, the device housing is generally configured as a plurality of sub-housings, so that the plurality of sub-housings are movable with respect to each other to accommodate folding between the flexible screens 300.

In a further technical scheme, the plurality of side hinge mechanisms are the same in kind, and among the plurality of hinge mechanisms in the same row, the plurality of side hinge mechanisms can include the first hinge mechanism that sets up in pairs and the second hinge mechanism that sets up in pairs, and the first hinge mechanism that sets up in pairs uses central hinge mechanism as symmetry center symmetry setting, and the second hinge mechanism that sets up in pairs is located the one side that first hinge mechanism was facing away from central hinge mechanism respectively, and the arrangement direction of adjacent first hinge mechanism and second hinge mechanism is opposite. Under the condition, the plurality of side hinge mechanisms with the same types are arranged in the forward and reverse directions, so that the weight of the electronic equipment is balanced, and the influence of unbalance weight on the use experience of a user is avoided.

In an alternative solution, the plurality of hinge mechanisms may be arranged in at least two rows, two adjacent rows of hinge mechanisms are arranged at intervals, and two adjacent rows of hinge mechanisms are arranged in a one-to-one opposite manner. Under this kind of circumstances, through setting up multirow hinge mechanism can avoid arranging the hinge mechanism of great model, also convenient change after local hinge mechanism takes place to damage simultaneously, also can reduce cost of maintenance.

In this embodiment of the present application, in the plurality of hinge mechanisms in the same row, the types of the central hinge mechanism and the side hinge mechanisms may be the same, that is, the structures may be identical, or the types of the central hinge mechanism and the side hinge mechanisms may not be the same, as shown in fig. 1 to 3.

In the embodiment of the application, a plurality of hinge mechanisms may be disposed along the length direction of the flexible screen 300, so that the electronic device can be folded for a plurality of times along the length direction thereof. In this case, the electronic device is more easily bent into a bracelet or S-shaped fitting,

referring to fig. 4 to 18 again, the embodiment of the present application discloses a hinge mechanism, and it should be noted that an electronic device is configured with a flexible screen 300, the folding of the electronic device can implement the folding of the flexible screen 300, and the unfolding of the electronic device can implement the unfolding of the flexible screen 300.

The hinge mechanism disclosed in the embodiment of the present application includes a hinge base 100 and two rotation support mechanisms 200.

The hinge base 100 is the base portion of the hinge, and the hinge base 100 is capable of providing a mounting base for the other components of the hinge mechanism.

Two rotational support mechanisms 200 may be used to support a flexible screen 300 of an electronic device. In the embodiment of the present application, two rotation supporting mechanisms 200 are respectively connected to two opposite sides of the hinge base 100, and both rotation supporting mechanisms 200 can rotate relative to the hinge base 100. The two rotation support mechanisms 200 are rotatable relative to each other so that the hinge mechanism is switchable between a first folded state and a second folded state. Of course, the hinge mechanism can be switched between the first folded state and the second folded state, and then the corresponding region of the electronic device can be realized between the first folded state and the second folded state. Of course, the hinge mechanism can also be in an unfolded state, and thus the corresponding region of the electronic device can be in an unfolded state, as shown in fig. 6.

In the embodiment of the present application, the rotation support mechanism 200 includes a rotation shaft 210, a hinge rotation plate 220, and a hinge movable plate 230.

The rotation shaft 210 is rotatably provided to the hinge base 100 so as to be rotatable with respect to the hinge base 100. Specifically, the hinge base 100 may be provided with a mounting hole, and the rotation shaft 210 may be mounted in the mounting hole, thereby implementing a rotational mounting through shaft hole engagement. Of course, the rotational shaft 210 may also be rotatably mounted on the hinge base 100 by bearings. Alternatively, the hinge base 100 may have the sleeve 110 fixed thereto, and the rotation shaft 210 may be engaged with the sleeve 110, thereby achieving a rotational engagement with the hinge base 100.

In the same rotation support mechanism 200, the hinge rotation plate 220 is rotatably connected to the hinge base 100 through the rotation shaft 210, that is, the hinge rotation plate 220 can rotate with respect to the hinge base 100 following the rotation shaft 210. Alternatively, the hinge rotation plate 220 is fixedly connected to the rotation shaft 210, in which case, rotation of the rotation shaft 210 drives the hinge rotation plate 220 to rotate together. The hinge rotating plate 220 is provided with a receiving groove 221 adjacent to a first end of the rotating shaft 210, and a second end of the hinge rotating plate 220 away from the rotating shaft 210 is a first supporting portion 222. That is, the distance between the second end of the hinge rotation plate 220 and the rotation shaft 210 is greater than the distance between the first end of the hinge rotation plate 220 and the rotation shaft 210. The first support portion 222 can play a supporting role.

The rotation shaft 210 is provided with a decelerator 240, so that each rotation support mechanism 200 can be configured with the decelerator 240. The decelerator 240 has a rotation output portion 241, and the rotation output portion 241 is rotatable with the rotation shaft 210. The rotation speed of the rotation output portion 241 is smaller than that of the rotation shaft 210 by the decelerator 240.

The hinge movable plate 230 includes a second supporting portion 231, and the second supporting portion 231 is at least partially located within the receiving recess 221. The second support portion 231 can also play a supporting role, and the second support portion 231 can support the flexible screen 300 together with the first support portion 222.

In the embodiment of the present application, the rotation output portion 241 is rotationally connected to the hinge movable plate 230, and the rotation of the rotation output portion 241 can drive the hinge movable plate 230 to rotate, so that the hinge movable plate 230 is movably matched with the hinge movable plate 220, and the hinge movable plate 230 can relatively move relative to the hinge movable plate 220.

As described above, during the rotation of the rotation shaft 210, the rotation speed of the rotation shaft 210 is made greater than the rotation speed of the rotation output portion 241 due to the presence of the decelerator 240, and thus the rotation speed of the hinge rotation plate 220 is made greater than the rotation speed of the hinge movable plate 230, in which case the hinge movable plate 230 can move with respect to the hinge rotation plate 220, and thus the position of the second support portion 231 can be changed within the accommodation groove 221.

As described above, the hinge mechanism has a first folded state and a second folded state. Wherein:

in the case where the hinge mechanism is in the first folded state, the notches of the receiving grooves 221 of the two rotation supporting mechanisms 200 are opposite, and the second supporting portion 231 is moved to the escape position with respect to the hinge rotation plate 220 toward a direction away from the notches of the receiving grooves 221, in this case, a portion of the space of the receiving grooves 221 of the two rotation supporting mechanisms 200 adjacent to the notches can be released, thereby forming a larger receiving space to receive the folded redundant area of the flexible screen 300, so that it is possible to avoid the problem that the flexible screen 300 is excessively pressed to be folded or broken due to a smaller folding radius when the electronic apparatus is folded inward.

In the case where the hinge mechanism is in the second folded state, the notches of the receiving grooves 221 of the two rotation support mechanisms 200 are opposite, and the second support portion 231 is moved to the support position with respect to the hinge rotation plate 220 toward the direction approaching the notches of the receiving grooves 221, in which case the second support portion 231 cooperates with the first support portion 222, thereby achieving better support of the flexible screen 300.

The hinge mechanism disclosed in the embodiment of the present application includes two opposite side rotation support mechanisms 200 respectively connected to the hinge base, and each rotation support mechanism 200 can rotate relative to the hinge base 100, so that the hinge mechanism can be switched between a first folded state and a second folded state. In the case where the hinge mechanism is in the first folded state, since the decelerator 240 can move the hinge movable plate 230 to the escape position in a direction away from the notch of the accommodation groove 221 in the process of rotating and folding, the notches of the accommodation grooves 221 of the two rotation support mechanisms 200 can be opposite, and a larger accommodation space is formed to accommodate the bending region of the flexible screen 300, which can certainly avoid the problem of breakage of the flexible screen 300 due to the excessively small bending radius in the folding process.

Meanwhile, in the case where the hinge mechanism is in the second folded state, the notches of the receiving grooves 221 of the two rotation support mechanisms 200 are disposed opposite to each other, and the second support portion 231 is moved to the support position with respect to the hinge rotation plate 220 toward a direction approaching the notch of the receiving groove 221, in which case the second support portion 231 can support the region of the flexible screen 300 opposite to the notch of the receiving groove 221, thereby being capable of better supporting the flexible screen 300.

The hinge mechanism disclosed by the embodiment of the application can realize bidirectional folding, namely folding in a first direction and then switching to a first folding state, and folding in a second direction and then switching to a second folding state. The first direction is opposite to the second direction. The electronic equipment adopting the hinge mechanism disclosed by the embodiment of the application can realize bidirectional folding, and finally the use scene of the electronic equipment is richer.

As described above, the rotation output portion 241 is also rotated during the rotation of the rotation shaft 210, except that the rotation speed of the rotation output portion 241 is low, thereby causing the rotation speed of the hinge movable plate 230 to be less than that of the hinge rotation plate 220. Based on this, in an alternative, the rotation output portion 241 may be rotatably coupled to the hinge movable plate 230 through a pull rod 250, a first end of the pull rod 250 being rotatably coupled to the rotation output portion 241, and a second end of the pull rod 250 being rotatably coupled to the hinge movable plate 230. Such a structure can make the hinge flap 230 more flexible, and can be better distant from the notch of the accommodation groove 221 or close to the notch of the accommodation groove 221.

In the hinge mechanism disclosed in the embodiment of the present application, the switching between the first folded state and the second folded state of the hinge mechanism may be performed by manual manipulation. In an alternative, the rotation shafts 210 of the two rotation supporting mechanisms 200 may be both optical axes, that is, there is no power transmission between the rotation shafts 210 of the two rotation supporting mechanisms 200. During the operation, the operator can drive the two rotation support mechanisms 200 to rotate, so as to realize the rotation of the rotation shafts 210 of the two rotation support mechanisms 200 relative to the hinge base 100. In this configuration, the operator can control one of the rotation support mechanisms 200 to rotate in one direction with respect to the hinge base 100, and can also control the other of the rotation support mechanisms 200 to rotate in the other opposite direction with respect to the hinge base 100, thereby enabling the hinge mechanism to be in the first folded state or the second folded state, as shown in fig. 14 or 17.

Of course, the operator can control the two rotation supporting mechanisms 200 to rotate towards the same direction, so that the hinge mechanism forms another state, as shown in fig. 18, and further meets the requirement on the folding state of the electronic device.

In another alternative, the rotation shafts 210 of the two rotation support mechanisms 200 are each provided with a second gear 2100, and the second gear 2100 of one rotation support mechanism 200 is meshed with the second gear 2100 of the other rotation support mechanism 200. In this case, the two rotation support mechanisms 200 are engaged to realize the synchronization and the reverse rotation, and thus the two rotation support mechanisms 200 can be ensured to have good synchronization.

In a further embodiment, both of the rotation supporting mechanisms 200 include an elastic mechanism 2200, and the elastic mechanism 2200 includes a first engagement mechanism 2210, a second engagement mechanism 2220, and an elastic member 2230, wherein:

the rotation shaft 210 may include a first shaft section 211 and a second shaft section 212, the first engagement mechanism 2210 is fixed at an end of the first shaft section 211 facing the second shaft section 212, the speed reducer 240 is disposed on the first shaft section 211, the second engagement mechanism 2220 is fixed at an end of the second shaft section 212 facing the first shaft section 211, the second shaft section 212 is movably disposed on the hinge base 100 along an axial direction thereof, the first engagement mechanism 2210 is engaged with the second engagement mechanism 2220 and can rotate relatively, the elastic member 2230 is elastically positioned between the hinge base 100 and the second engagement mechanism 2220, and the elastic member 2230 can drive the second engagement mechanism 2220 to elastically abut against the first engagement mechanism 2210. In this case, when a user applies a large external force, the engaging force between the first engaging mechanism 2210 and the second engaging mechanism 2220 can be overcome, so that the relative rotation is achieved, and thus the relative rotation between the rotation support mechanisms 200 is achieved. In the case where the user withdraws the external force, the engagement force between the first engagement mechanism 2210 and the second engagement mechanism 2220 enables the two rotation support mechanisms 200 to hover in the current unfolded state by the engagement between the two second gears 2100, thereby realizing the hinge mechanism having a variety of unfolding angles.

In the alternative, the hinge base 100 may have the sleeve 110 secured thereto, with the second shaft segment 212 passing through the sleeve 110 and slidably engaging the sleeve 110 to effect a movable arrangement of the second shaft segment 212 on the hinge base 100 in its axial direction. At the same time, the sleeve 110 can be rotatably coupled to the second shaft section 212 by shaft hole engagement.

In the embodiment of the present application, the first end of the second shaft section 212 is provided with a connecting protrusion 2121, the second end of the second shaft section 212 is provided with a second engagement mechanism 2220, and the sleeve member 110 is located between the two ends of the second shaft section 212; one end of the elastic member 2230 is fixedly connected with the sleeve 110, the other end of the elastic member 2230 is fixedly connected with the connecting protrusion 2121, and the elastic member 2230 can drive the connecting protrusion 2121 to move toward the first shaft section 211.

In this embodiment, the hinge base 100 may be provided with the avoidance groove 120, where the first end of the second shaft section 212 is disposed opposite to the avoidance groove 120, and may be slidably matched with the avoidance groove 120, so as to slide relative to the avoidance groove 120. The connecting projection 2121 can be in limited contact with the surface where the notch of the escape groove 120 is located as the second shaft section 212 moves. In this case, the connecting protrusion 2121 can cooperate with the avoidance groove 120 to improve the assembly performance, and meanwhile, the surface where the notch of the avoidance groove 120 is located can play a limiting role on the movement of the second shaft section 212, so as to avoid excessive movement of the second shaft section 212.

In the embodiment of the present application, the supporting surface of the second supporting portion 231 may be provided with a first elastic layer 260, and the first elastic layer 260 may be a foam layer. In the case where the hinge mechanism is in the second folded state, the second supporting portion 231 is in the supporting position, and the first elastic layer 260 can function to better support the flexible screen 300. Meanwhile, the first elastic layer 260 can better compensate the height difference with the first supporting portion 222 through elastic deformation thereof, so as to achieve a better cooperative supporting effect.

In the alternative, a second elastic layer 270 may be provided between the region of the substrate 232 extending to the back side of the first support portion 222 and the first support portion 222. The structure can enable the hinge mechanism to be in the second folded state, and the first supporting portion 222 can form elastic fit between the second elastic layer 270 and the substrate 232, so that the structural stability of the hinge mechanism in the second folded state is improved.

The second supporting portion 231 is movable in the receiving groove 221 during the folding of the hinge mechanism. In a further embodiment, the inner wall of the accommodating recess 221 may be provided with a through hole 2211, and at least a portion of the second supporting portion 231 may enter and exit the accommodating recess 221 through the through hole 2211, in which case the second supporting portion 231 is not interfered by the inner wall of the accommodating recess 221, thereby being capable of moving in a direction away from the notch of the accommodating recess 221 more flexibly.

In the hinge mechanism disclosed in the embodiment of the present application, the hinge movable plate 230 may include a base plate 232, and the second supporting portion 231 is disposed on the base plate 232. The substrate 232 passes through the through hole 2211, and the substrate 232 extends to the back side of the first support portion 222, i.e., to the side facing away from the support surface of the first support portion 222. In this case, the substrate 232 gradually approaches the side surface of the first support portion 222 during the process of folding the hinge mechanism to the second folded state, and the substrate 232 is in limited contact with the second support portion 231 when the hinge mechanism is in the second folded state, so that the purpose of constraining the hinge rotating plate 220 and the hinge movable plate 230 can be achieved, and the first support portion 222 and the second support portion 231 are more easily cooperated to support the flexible screen 300 together.

In this embodiment, the first end of the hinge movable plate 230 may be opposite to the first end of the hinge rotating plate 220, and the first link 280 may be rotatably connected therebetween, that is, one end of the first link 280 is rotatably connected to the first end of the hinge movable plate 230, and the other end of the first link 280 is rotatably connected to the hinge rotating plate 220.

The second end of the hinge movable plate 230 is opposite to the second end of the hinge rotating plate 220, and a second link 290 is rotatably connected therebetween, that is, one end of the second link 290 is rotatably connected to the second end of the hinge movable plate 230, and the other end of the second link 290 is rotatably connected to the second end of the hinge rotating plate 220. In this case, the hinge movable plate 230 and the hinge rotating plate 220 are connected by the first link 280 and the second link 290, and the hinge movable plate 230 can translate with respect to the hinge rotating plate 220 by the first link 280 and the second link 290. During rotation of the hinge mechanism, the hinge movable plate 230 has a higher degree of freedom, thereby facilitating movement thereof with respect to the hinge rotating plate 220. Meanwhile, the first link 280 and the second link 290 can enable the hinge movable plate 230 to translate, so that interference is not easy to generate in the rotation direction to affect rotation, and meanwhile, the hinge mechanism can be folded regularly in the first folding state and the second folding state.

In an alternative, the hinge rotating plate 220 may be provided with a first guide receiving groove 220a and a second guide receiving groove 220b, and an end of the first link 280 is rotatably coupled to the first guide receiving groove 220a and is slidable with respect to the first guide receiving groove 220 a; the end of the second link 290 is rotatably connected to the second guide receiving groove 220b and is slidable with respect to the second guide receiving groove 220b, and a portion of the first link 280 extends into the first guide receiving groove 220a and a portion of the second link 290 extends into the second guide receiving groove 220b when the hinge mechanism is in the second folded state. In this case, a portion of the first link 280 is received in the first guide receiving groove 220a, and a portion of the second link 290 is received in the second guide receiving groove 220b, so that the hinge mechanism is more compact to be foldable in the second folded state, and the hinge rotating plate 220 and the hinge movable plate 230 are more easily moved toward each other.

In this embodiment, the first end of the hinge rotating plate 220 may be provided with a limit bone 223, and the limit bone 223 may be in limit fit with the hinge movable plate 230 in the case that the hinge mechanism is in the first folded state. In this case, the second support portion 231 of the hinge movable plate 230 can stop further away from the notch of the accommodation groove 221, avoiding excessive distance of the second support portion 231.

In this embodiment, the structure of the hinge base 100 may be various, in an alternative solution, the hinge base 100 may include a first cover plate 130 and a second cover plate 140, where the first cover plate 130 and the second cover plate 140 are both disposed between the two rotation support mechanisms 200, and the first cover plate 130 and the second cover plate 140 are disposed opposite to each other, and in the case that the hinge mechanism is in the first folded state, the hinge rotation plates 220 of the two rotation support mechanisms 200 are in spacing fit with the first cover plate 130, so as to avoid excessive rotation of the two rotation support mechanisms 200. In a specific operation process, the hinge rotating plates 220 of the two rotating support mechanisms 200 and the first cover plate 130 are limited, and when they cannot rotate further, it is indicated that the hinge mechanism is in the first folded state.

In the case that the hinge mechanism is in the second folded state, the hinge movable plates 230 of the two rotation supporting mechanisms 200 are in limit fit with the second cover plate 140. In a specific operation process, the hinge rotating plates 220 of the two rotating support mechanisms 200 are in a limit fit with the second cover plate 140, and when the two rotating support mechanisms cannot rotate further, the hinge mechanisms are in the second folded state. And this limit fit can prevent excessive rotation of the two rotation support mechanisms 200.

The hinge mechanism disclosed in the embodiments of the present application may further include a driving mechanism 400. The driving mechanism 400 is used for driving the rotating shafts 210 of the two rotating support mechanisms 200 to rotate, so that the hinge mechanism is switched between a first folding state and a second folding state.

In the embodiment of the present application, the types and assembly relationships of the driving mechanism 400 may be various, and in an alternative solution, the rotation shafts 210 of the two rotation supporting mechanisms 200 may be both optical axes, that is, no power transmission is possible between the rotation shafts 210 of the two rotation supporting mechanisms 200. The driving mechanism 400 may include a first driving motor 410 and a second driving motor 420, each of the first driving motor 410 and the second driving motor 420 being disposed on the hinge base 100. The first driving motor 410 is drivingly connected to the rotation shaft 210 of one rotation supporting mechanism 200, thereby driving the rotation shaft 210 to rotate. The second driving motor 420 is in driving connection with the rotation shaft 210 of the other rotation supporting mechanism 200, thereby driving the rotation shaft 210 to rotate. In this structure, the rotation of the rotation shafts 210 of the two rotation supporting mechanisms 200 are independently driven by the first driving motor 410 and the second driving motor 420, respectively, so that interference between the two rotation supporting mechanisms can be avoided in the driving process, and the respective driving structures have the advantage of simple structure.

Meanwhile, since the rotation of the two rotation supporting mechanisms 200 is driven by the first driving motor 410 and the second driving motor 420, respectively, the two rotation supporting mechanisms 200 are driven by the driving mechanism 400, and the rotation directions are not interfered with each other and are more free, so that more states of folding or unfolding of the hinge mechanism can be realized.

In another alternative, the drive mechanism 400 may include a third drive motor 430 and two first gears 440. The third driving motor 430 is provided on the hinge base 100. The two first gears 440 are disposed on the rotating shafts 210 of the two rotation supporting mechanisms 200, respectively, and the two first gears 440 are engaged with each other. The third driving motor 430 is in driving connection with the rotation shaft 210 of one of the two rotation supporting mechanisms 200. The third driving motor 430 drives the rotation shafts 210 of the two rotation supporting mechanisms 200 to rotate through the two first gears 440 engaged with each other. In this case, the hinge mechanism can drive the rotation shafts 210 of the two rotation support mechanisms 200 to simultaneously rotate by one third driving motor 430, so that the hinge mechanism can be made unnecessary to be provided with more driving motors, which can certainly reduce the manufacturing cost.

Meanwhile, the rotation shafts 210 of the two rotation supporting mechanisms 200 are meshed with each other through the two first gears 440 to realize power transmission, so that good synchronism of rotation of the rotation shafts 210 can be realized.

The hinge mechanism disclosed in the embodiment of the present application can be applied to an electronic device, which may include a main board, and the third driving motor 430 is electrically connected with the main board, so as to be powered by the main board.

In still another alternative, both ends of the hinge base 100 may be provided with the first magnetic member 500 and the second magnetic member 600, respectively, and the opposite ends of the first magnetic member 500 and the second magnetic member 600 may have opposite magnetic properties. In this case, the driving mechanism 400 may include a first driving motor 410 and a first wire set 450, the first driving motor 410 being connected to the rotation shaft 210 of one rotation supporting mechanism 200. The first drive motor 410 is electrically connected to the first wire set 450. The first wire set 450 is disposed on at least one of the hinge rotation plate 220 and the hinge movable plate 230 and is rotatable therewith. The rotation of the first wire set 450 may generate electric energy for the first driving motor 410 to drive the corresponding rotation shaft 210 to rotate. In a specific operation process, the user may manually drive the rotation supporting mechanism 200 to rotate, in which the first wire set 450 follows the rotation supporting mechanism 200 to rotate, and cut magnetic lines of force in the magnetic field formed by the first magnetic member 500 and the second magnetic member 600, and finally the first wire set 450 generates induced current, thereby achieving the purpose of supplying power to the first driving motor 410. In this case, in the manual operation process of the user, the first driving motor 410 can play a role of assisting force, so that the user can conveniently operate the electronic device in a folding manner.

Similarly, the driving mechanism 400 may further include a second driving motor 420 and a second wire set 460, where the second driving motor 420 is connected to the rotating shaft 210 of the other rotating support mechanism 200, and the second driving motor 420 is electrically connected to the second wire set 460. The second wire set 460 is provided on at least one of the hinge rotation plate 220 and the hinge movable plate 230 of the other rotation support mechanism 200 and is rotatable therewith. The rotation of the second wire set 460 may generate electric energy for the second driving motor 420 to drive the corresponding rotation shaft 210 to rotate. In a specific working process, the user can manually drive the rotation supporting mechanism 200 to rotate, in this process, the second wire set 460 follows the rotation supporting mechanism 200 to cut magnetic lines of force in the magnetic field formed by the first magnetic element 500 and the second magnetic element 600, and finally the second wire set 460 generates induced current, thereby achieving the purpose of supplying power to the second driving motor 420. Also in this case, in the process of manual manipulation by the user, the second driving motor 420 can play a role of assisting force, and thus can facilitate the manipulation of folding the electronic device by the user.

Of course, the first driving motor 410 and the second driving motor 420 may be respectively connected with electricity, and the first wire set 450 and the second wire set 460 may generate electric energy in the process of driving the two rotation supporting mechanisms 200 to rotate, so as to supplement the electric energy consumption of the first driving motor 410 and the second driving motor 420, and achieve the purpose of energy saving. It is apparent that the driving mechanism 400 of the above-described structure is advantageous in reducing power consumption to the hinge mechanism.
