Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

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

As shown in fig. 1-18, 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 support 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 correspond to the plurality of hinge mechanisms one to one, and two adjacent first regions 310 are connected by the second regions 320. Since the plurality of first regions 310 correspond to the plurality of hinge mechanisms one to one, the second region 320 corresponds to a space between adjacent two hinge mechanisms.

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

The electronic equipment disclosed in the embodiment of the application is improved through the related technology, so that the electronic equipment comprises a plurality of hinge mechanisms, the flexible screen 300 can be supported by the hinge mechanisms, and then the folding or unfolding of the flexible screen 300 between corresponding areas can be realized along with the hinge mechanisms. In a specific folding process, the plurality of second sub-regions 312 may be symmetrically disposed by the central hinge mechanism with the first sub-region 311 as a center of symmetry. Meanwhile, the plurality of second sub-regions 312 can be folded or unfolded through a side hinge mechanism. It is obvious that the electronic device disclosed in the embodiments of the present application can be folded into various shapes, and thus has better folding performance.

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

In a further technical scheme, a plurality of side hinge mechanisms of the same kind, in a plurality of hinge mechanisms of same row, a 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 to set up as symmetry center symmetry, and the second hinge mechanism that sets up in pairs is located the one side that first hinge mechanism dorsad central hinge mechanism respectively, and adjacent first hinge mechanism and second hinge mechanism's arrangement direction are opposite. Under the condition, the side hinge mechanisms with the same type are arranged in the forward and reverse directions, so that the weight of the electronic equipment is balanced, and the influence on the use experience of a user due to the unbalanced weight is avoided.

In an alternative, the plurality of hinge mechanisms may be arranged in at least two rows, two adjacent rows of the hinge mechanisms are arranged at intervals, and two adjacent rows of the hinge mechanisms are arranged in one-to-one opposition. Under the condition, the arrangement of the hinge mechanisms with larger models can be avoided by arranging a plurality of rows of hinge mechanisms, the damaged hinge mechanisms can be replaced conveniently at local parts, and the maintenance cost can be reduced.

In the embodiment of the present application, in a plurality of hinge mechanisms in the same row, the center hinge mechanism and the side hinge mechanism may be of the same type, that is, have the same structure, or the center hinge mechanism and the side hinge mechanism are not of the same type, or the center hinge mechanism and the side hinge mechanism are of different types, as shown in fig. 1 to 3.

In the embodiment of the present application, a plurality of hinge mechanisms may be disposed along the length direction of the flexible screen 300, thereby enabling the electronic device to be folded in the length direction thereof a plurality of times. In this case, the electronic device is easily bent into a bracelet or an 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 the electronic device is configured with a flexible screen 300, the folding of the electronic device can realize the folding of the flexible screen 300, and the unfolding of the electronic device can realize 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 can provide 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 support mechanisms 200 are respectively connected to two opposite sides of the hinge base 100, and both rotation support mechanisms 200 can rotate relative to the hinge base 100. The two rotary support mechanisms 200 are relatively rotatable so that the hinge mechanism can be switched between the first folded state and the second folded state. Of course, the hinge mechanism can be switched between the first folded state and the second folded state, and the corresponding region of the electronic device can be switched between the first folded state and the second folded state. Of course, the hinge mechanism can also be in a deployed state, which in turn enables a corresponding area of the electronic device to be deployed as well, as shown in fig. 6.

In the embodiment of the present application, the rotary support mechanism 200 includes a rotary shaft 210, a hinge rotary 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 rotating shaft 210 may be mounted in the mounting hole, so that the rotating mounting is realized through the shaft hole matching. Of course, the rotating shaft 210 may also be rotatably mounted on the hinge base 100 by a bearing. Alternatively, the hinge base 100 may be secured with the sleeve 110 and the shaft 210 may be engaged with the sleeve 110 to achieve 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 via the rotation shaft 210, that is, the hinge rotation plate 220 can rotate relative 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 the rotation of the rotation shaft 210 drives the hinge rotation plate 220 to rotate together. A first end of the hinge rotation plate 220 adjacent to the rotation shaft 210 is formed with a receiving groove 221, and a second end of the hinge rotation plate 220 away from the rotation shaft 210 is a first supporting portion 222. That is, the distance between the second end of the hinge rotating plate 220 and the rotation shaft 210 is greater than the distance between the first end of the hinge rotating plate 220 and the rotation shaft 210. The first support portion 222 can exert a supporting function.

The rotation shaft 210 is provided with a speed reducer 240, enabling each rotation support mechanism 200 to be provided with the speed reducer 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 less than that of the rotation shaft 210 by the reducer 240.

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

In the embodiment of the present application, the rotation output part 241 is rotatably connected to the hinge movable plate 230, the rotation of the rotation output part 241 can drive the hinge movable plate 230 to rotate, and the hinge movable plate 230 is movably engaged with the hinge rotatable plate 220, so that the hinge movable plate 230 can move relative to the hinge rotatable plate 220.

As described above, during the rotation of the rotating shaft 210, due to the reducer 240, the rotation speed of the rotating shaft 210 is greater than the rotation speed of the rotation output portion 241, and thus the rotation speed of the hinge rotating plate 220 is greater than the rotation speed of the hinge moving plate 230, in which case the hinge moving plate 230 can move relative to the hinge rotating plate 220, and thus the position of the second supporting portion 231 within the receiving groove 221 can be changed.

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

in the case where the hinge mechanism is in the first folding state, the notches of the receiving grooves 221 of the two rotation support mechanisms 200 are opposite to each other, and the second support portion 231 moves to the avoiding position with respect to the hinge rotation plate 220 toward the direction away from the notch of the receiving groove 221, in this case, a partial space of the receiving groove 221 of the two rotation support mechanisms 200 adjacent to the notch can be released, so that a large receiving space is formed to receive the bending redundant region of the flexible screen 300, and thus, the problem that the flexible screen 300 is excessively squeezed to be folded or damaged due to a small bending radius when the electronic device is folded inward can be avoided.

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 opposed to each other, and the second support portion 231 is moved to the support position with respect to the hinge rotation plate 220 toward the direction close to the notch of the receiving groove 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 rotation support mechanisms 200 respectively connected to the hinge base, and each rotation support mechanism 200 is capable of rotating with respect to the hinge base 100, so that the hinge mechanism can be switched between the first folding state and the second folding state. In the case that the hinge mechanism is in the first folding state, since the reducer 240 can move the hinge movable plate 230 to the avoiding position in the direction away from the notches of the accommodating grooves 221 during the rotating and folding process, the notches of the accommodating grooves 221 of the two rotating support mechanisms 200 can be made to be opposite to each other, and a larger accommodating space is formed to accommodate the bending area of the flexible screen 300, which undoubtedly can avoid the problem of breakage of the flexible screen 300 caused by an excessively small bending radius during the folding process.

Meanwhile, in the case where the hinge mechanism is in the second folded state, the notches of the accommodation 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 the direction close to the notch of the accommodation 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 accommodation groove 221, so that the flexible screen 300 can be supported well.

The hinge mechanism disclosed in the embodiment of the application can realize bidirectional folding, namely, the hinge mechanism is folded in the first direction and then switched to the first folding state, and is folded in the second direction and then switched to the 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 be folded in two directions, and finally, the use scene of the electronic equipment can be richer.

As described above, the rotation output part 241 rotates during the rotation of the rotation shaft 210, but the rotation speed of the rotation output part 241 is low, so that the rotation speed of the hinge moving plate 230 is lower than that of the hinge rotating plate 220. Based on this, in an alternative scheme, the rotation output part 241 may be rotatably connected to the hinge plate 230 through a pull rod 250, a first end of the pull rod 250 is rotatably connected to the rotation output part 241, and a second end of the pull rod 250 is rotatably connected to the hinge plate 230. This structure enables the hinge moving plate 230 to be more flexible, and to be better away from the notch of the receiving groove 221 or close to the notch of the receiving groove 221.

In the hinge mechanism disclosed in the embodiment of the present application, switching of the hinge mechanism between the first folded state and the second folded state may be performed by manual manipulation. In an alternative, the rotating shafts 210 of the two rotating support mechanisms 200 can be optical shafts, that is, no power transmission is performed between the rotating shafts 210 of the two rotating support mechanisms 200. During the manipulation, the operator may drive the two rotation support mechanisms 200 to rotate, thereby realizing the rotation of the rotation shafts 210 of the two rotation support mechanisms 200 relative to the hinge base 100. In this structure, an operator can control one of the rotation support mechanisms 200 to rotate in one direction relative to the hinge base 100, and can also control the other rotation support mechanism 200 to rotate in the other opposite direction relative to the hinge base 100, so that the hinge mechanism can 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 support mechanisms 200 to rotate towards the same direction, so that the hinge mechanism is in another state, as shown in fig. 18, and further meet more requirements for the folded state of the electronic device.

In another alternative, the rotating shafts 210 of both the rotary support mechanisms 200 are provided with the second gear 2100, and the second gear 2100 of one rotary support mechanism 200 is engaged with the second gear 2100 of the other rotary support mechanism 200. In this case, the two rotation support mechanisms 200 are engaged to achieve synchronous and reverse rotation, and good synchronism of the two rotation support mechanisms 200 can be ensured.

In a further technical solution, both the rotary support mechanisms 200 may include an elastic mechanism 2200, and the elastic mechanism 2200 may include a first engagement mechanism 2210, a second engagement mechanism 2220, and an elastic member 2230, wherein:

the rotating shaft 210 may include a first shaft segment 211 and a second shaft segment 212, a first engagement mechanism 2210 is fixed on an end of the first shaft segment 211 facing the second shaft segment 212, a speed reducer 240 is disposed on the first shaft segment 211, a second engagement mechanism 2220 is fixed on an end of the second shaft segment 212 facing the first shaft segment 211, the second shaft segment 212 is 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, an 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 large external force is applied by the user, the engagement force between the first engagement mechanism 2210 and the second engagement mechanism 2220 can be overcome to achieve the relative rotation, and thus the relative rotation between the rotary support mechanisms 200. In the case where the user withdraws from the external force, the engagement force between the first engagement mechanism 2210 and the second engagement mechanism 2220 enables the two rotary support mechanisms 200 to hover at the current deployed state through the engagement between the two second gears 2100, thereby realizing the hinge mechanism having various deployed angles.

In an alternative, the hinge base 100 may be fixed with the sleeve 110, and the second shaft section 212 passes through the sleeve 110 and is slidably fitted with the sleeve 110, so as to realize the movable arrangement of the second shaft section 212 on the hinge base 100 along the axial direction thereof. Meanwhile, the sleeve 110 can be matched with the second shaft section 212 through the shaft hole to realize the rotary connection.

In the present embodiment, 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 to the sleeve 110, and the other end of the elastic member 2230 is fixedly connected to the connecting protrusion 2121, so that the elastic member 2230 can drive the connecting protrusion 2121 to move toward the first shaft segment 211.

In the embodiment of the present application, the hinge base 100 may be provided with an avoiding groove 120, and the first end of the second shaft section 212 is disposed opposite to the avoiding groove 120 and can be slidably engaged with the avoiding groove 120, so as to be able to slide relative to the avoiding groove 120. The connecting protrusion 2121 can be in limit contact with the surface where the notch of the avoiding groove 120 is located along with the movement of the second shaft section 212. Under the condition, the connecting protrusion 2121 can be matched with the avoiding groove 120 to improve the assembling performance, and meanwhile, the surface where the notch of the avoiding groove 120 is located can limit the movement of the second shaft section 212, so that the second shaft section 212 is prevented from moving excessively.

In the present embodiment, 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. With the hinge mechanism in the second folded state, the second support portion 231 is in the support position, and the first elastic layer 260 can function to better support the flexible screen 300. Meanwhile, the first elastic layer 260 can compensate for the height difference with the first support portion 222 through its elastic deformation, so as to achieve a better cooperative support effect.

Alternatively, a second elastic layer 270 may be disposed between a region of the substrate 232 extending to the backside of the first support portion 222 and the first support portion 222. With the structure, under the condition that the hinge mechanism is in the second folding state, the first supporting part 222 can be elastically attached to the substrate 232 through the second elastic layer 270, so that the structural stability of the hinge mechanism in the second folding state can be improved.

During the folding of the hinge mechanism, the second support portion 231 moves in the receiving recess 221. In a further technical solution, the inner wall of the receiving groove 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 receiving groove 221 through the through hole 2211, in which case, the second supporting portion 231 may not be interfered by the inner wall of the receiving groove 221, so as to be more flexibly moved in a direction away from the notch of the receiving groove 221.

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, in the process of folding the hinge mechanism to the second folded state, the base plate 232 may gradually approach the side surface of the first support portion 222, and in the case that the hinge mechanism is in the second folded state, the base plate 232 is in spacing contact with the second support portion 231, so that the purpose of restraining the hinge rotating plate 220 and the hinge moving 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 the embodiment of the present application, the first end of the hinge movable plate 230 may be opposite to the first end of the hinge rotary 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 rotary plate 220.

The second end of the hinge movable plate 230 is opposite to the second end of the hinge rotary plate 220, and a second connecting rod 290 is rotatably connected therebetween, that is, one end of the second connecting rod 290 is rotatably connected to the second end of the hinge movable plate 230, and the other end of the second connecting rod 290 is rotatably connected to the second end of the hinge rotary plate 220. In this case, the hinge moving plate 230 and the hinge rotating plate 220 are connected by the first link 280 and the second link 290, and the hinge moving plate 230 is translatable with respect to the hinge rotating plate 220 by the first link 280 and the second link 290. The hinge movable plate 230 has a higher degree of freedom during the rotation of the hinge mechanism, thereby facilitating the movement thereof with respect to the hinge rotary plate 220. Meanwhile, the first link 280 and the second link 290 can make the hinge movable plate 230 horizontally move, so that interference is not easy to occur in the rotating direction to affect rotation, and the hinge mechanism can be folded regularly in the first folding state and the second folding state.

In an alternative scheme, the hinge rotating plate 220 may be provided with a first guiding receiving groove 220a and a second guiding receiving groove 220b, and an end of the first link 280 is rotatably connected to the first guiding receiving groove 220a and can slide relative to the first guiding receiving groove 220 a; the end of the second link 290 is rotatably connected to the second guide receiving groove 220b and can slide relative to the second guide receiving groove 220b, and when the hinge mechanism is in the second folded state, 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 220 b. 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 can be folded more compactly in the second folded state, which is more advantageous for the hinge rotating plate 220 and the hinge moving plate 230 to approach each other.

In the embodiment of the present application, the first end of the hinge rotating plate 220 may be provided with a limiting rib 223, and the limiting rib 223 may be in limiting fit with the hinge moving plate 230 when the hinge mechanism is in the first folding state. In this case, the second support portion 231 of the hinge movable plate 230 can stop further away from the notch of the receiving groove 221, avoiding the second support portion 231 from being excessively away.

The driving mechanism 400 may include a first driving motor 410 and a second driving motor 420, and the first driving motor 410 and the second driving motor 420 are both provided on the hinge base 100.

The first driving 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 rotating plate 220 and the hinge moving plate 230 and can rotate therewith. The rotation of the first wire set 450 can generate electric energy for the first driving motor 410 to drive the corresponding rotating shaft 210 to rotate. In a specific working process, a user can manually drive the rotary support mechanism 200 to rotate, in the process, the first wire group 450 rotates along with the rotary support mechanism 200, magnetic lines of force are cut in a magnetic field formed by the first magnetic member 500 and the second magnetic member 600, and finally the first wire group 450 generates induced current, so that the purpose of supplying power to the first drive motor 410 is achieved.

Similarly, the driving mechanism 400 may further include a second driving motor 420 and a second wire group 460, the second driving motor 420 is connected to the rotating shaft 210 of another rotating support mechanism 200, and the second driving motor 420 is electrically connected to the second wire group 460. The second wire set 460 is disposed on at least one of the hinge rotating plate 220 and the hinge moving plate 230 of the other rotary supporting mechanism 200 and can rotate therewith. The rotation of the second wire set 460 can generate electric energy for the second driving motor 420 to drive the corresponding rotating shaft 210 to rotate. In a specific working process, a user can manually drive the rotary supporting mechanism 200 to rotate, in this process, the second wire group 460 rotates along with the rotary supporting mechanism 200, and cuts magnetic lines in a magnetic field formed by the first magnetic member 500 and the second magnetic member 600, and finally the second wire group 460 generates induced current, so that the purpose of supplying power to the second driving motor 420 is achieved. In this case, the second driving motor 420 can assist the user to manually operate the electronic device, so that the user can conveniently operate the electronic device to fold the electronic device.

Of course, the first driving motor 410 and the second driving motor 420 may also be respectively powered on, and the first lead group 450 and the second lead group 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 above-structured drive mechanism 400 is advantageous in reducing power consumption to the hinge mechanism.
