DETAILED DESCRIPTION

[0052] The technical solution of the present application is further elaborated in detail below in conjunction with the accompanying drawings and specific embodiments of the specification.

[0053] In the embodiments of the present application, it should be noted that, unless otherwise specified and limited, the term "connection" should be understood in a broad sense. For example, it can be an electrical connection or internal connectivity between two components. It can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0054] It should be noted that the terms "first\second\third" involved in the embodiments of the present application are only used to distinguish similar objects, and do not represent a specific order for the objects. It is understandable that the specific order or sequence of "first\second\third" can be interchanged where permitted. It should be understood that the objects distinguished by "first\second\third" can be interchanged where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein.

[0055] The following combination Figures 1 to 7 The electronic device described in the embodiments of the present application is described in detail.

[0056] The electronic device includes: a first body 100, a connecting device 400, a second body 200 and a deformable screen 300. The connecting device 400 includes a flat panel group 410, and the flat panel group 410 includes at least four flat panels; the second body 200 is connected to the first body 100 through the connecting device 400; the deformable screen 300 includes a first part 310 fixed to the first body 100 and a second part 320 fixed to the second body 200, and a deformable part 330 located between the first part 310 and the second part 320.

[0057] like Figure 1 and Figure 5 As shown, if the first body 100 and the second body 200 are in the first device posture through the connecting device 400, the flat plate group 410 of the connecting device 400 constitutes a flat surface for supporting the deformed part 330 in the first state. At this time, the deformed part 330 in the first state is in a flat state based on the flat surface support.

[0058] If the first body 100 and the second body 200 are in the second device posture through the connecting device 400, the flat plate group 410 of the connecting device 400 constitutes an accommodating space for accommodating and protecting the deformed part 330 in the second state, and the accommodating space includes a polygonal space composed of at least four flat plates; the polygonal space formed by the flat plate group 410 can make the deformed part 330 in the second state teardrop shape or U-shape, thereby preventing the deformed part 330 from being damaged due to bending dead corners.

[0059] If the electronic device changes between the first device posture and the second device posture, each tablet in the tablet group 410 of the connecting device 400 switches between the flat surface and the accommodating space based on the motion of the corresponding motion track of each tablet.

[0060] In the related art, electronic devices generally include a door panel structure and a flexible screen structure; the deformation area of ​​the flexible screen structure can be supported by the door panel structure. However, during use, some door panel structures cannot move adaptively, and the door panel structure cannot stably support the deformation area of ​​the flexible screen structure, which makes the adaptability of the electronic device poor. For example, the passive door panel in the electronic device does not move with the relative movement of the two main bodies of the electronic device. The passive door panel only contacts some structures at a specific angle to force the passive door panel to move; at this time, since the passive door panel does not move all the time, the passive door panel cannot adapt to the deformation of the deformation area of ​​the flexible screen structure, resulting in a large contact force between the deformation area of ​​the flexible screen structure and the passive door panel, or the deformation area of ​​the flexible screen structure is spaced relatively large from the passive door panel, and the passive door panel cannot stably protect the deformation area of ​​the flexible screen structure. For example, if an electronic device falls, when the contact force between the passive door panel and the deformation area of ​​the flexible screen structure is large, the passive door panel may damage the deformation area of ​​the flexible screen structure under the action of the impact force; when the distance between the passive door panel and the deformation area of ​​the flexible screen structure is large, under the action of the impact force, the deformation area of ​​the flexible screen structure will move around and undergo a large displacement, which may easily cause damage to the deformation area of ​​the flexible screen structure.

[0061] In the implementation of the present application, if the electronic device changes between the first device posture and the second device posture, each tablet in the tablet group 410 of the connecting device 400 switches between the flat surface and the accommodating space based on the movement of the corresponding motion track of each tablet. At this time, each tablet can adapt to the deformation of the deformable part 330 and move, and each tablet and the deformable part 330 can always maintain a relatively stable positional relationship. In the process of the electronic device changing between the first device posture and the second device posture, each tablet can also always protect the deformable part 330 of the deformable screen 300.

[0062] In one application, if the electronic device falls while changing between the first device posture and the second device posture, at this time, since each flat plate and the deformation part 330 can always maintain a relatively stable positional relationship, at this time, through the limiting effect of each flat plate, the deformation part 330 will not undergo a large deformation, thereby preventing the deformation part 330 from being damaged due to excessive deformation due to the impact force during the falling process.

[0063] In the embodiments of the present application, the structure of the electronic device is not limited. For example, the electronic device may be a laptop computer. For another example, the electronic device may be a mobile phone. For another example, the electronic device may be a game console.

[0064] In the embodiment of the present application, the structure of the first body 100 is not limited. For example, the first body 100 may be a plate-shaped structure. For another example, the first body 100 may be a frame-shaped structure.

[0065] In the embodiment of the present application, the structure of the second body 200 is not limited. For example, the second body 200 may be a plate-like structure. For another example, the second body 200 may be a frame-like structure.

[0066] As an example, the first body 100 and the second body 200 are two bodies of a notebook computer. As another example, the first body 100 and the second body 200 are two bodies of a foldable mobile phone.

[0067] In the embodiment of the present application, the deformable screen 300 may be a flexible screen. The first portion 310 of the screen 300 may be fixedly connected to the first body 100 by means of snap connection, bonding, etc. The second portion 320 of the screen 300 may be fixedly connected to the second body 200 by means of snap connection, bonding, etc. The deformable portion 330 of the screen 300 is not fixed so that the deformable portion 330 of the screen 300 may be deformed adaptively.

[0068] The first device posture may be that the first body 100 and the second body 200 are in a flattened state, at which time, the angle between the first body 100 and the second body 200 may be 180 degrees. Here, the first body 100 and the second body 200 may meet the coplanar condition, at which time, the first body 100 and the second body 200 may be coplanar or substantially coplanar.

[0069] In the first device posture, the flat panel group 410 of the connecting device 400 forms a flat surface, which is used to support the deformable part 330 in the first state. At this time, the deformable part 330 is in a flat state, and the screen 300 as a whole is a larger flat screen 300, so that the user can watch videos or input information through the larger flat screen 300.

[0070] The second device posture may be that the first body 100 and the second body 200 are in a folded state, at which time, the angle between the first body 100 and the second body 200 may be 0 degrees. Here, the first body 100 and the second body 200 may be stacked together to facilitate storage and carrying of the electronic device.

[0071] In the second device posture, the flat plate group 410 of the connecting device 400 forms an accommodating space, and the deformed portion can be accommodated by the accommodating space. Since the accommodating space includes a polygonal space composed of at least four flat plates, at this time, the deformed portion 330 in the second state can form a smooth arc structure, for example, Figure 7 As shown, the deformation part 330 in the second state is in a teardrop shape; for another example, the deformation part 330 in the second state is in a U shape, so that the accommodation space can also prevent the deformation part from being crushed due to excessive local deformation. At the same time, the accommodation space can also protect the deformation part 330 in the second state, preventing the deformation part from being damaged by foreign objects during the process of storing and carrying the electronic device.

[0072] In some optional implementations of the embodiments of the present application, the deformable portion 330 changes between the first state and the second state as the electronic device changes between the first device posture and the second device posture; each of the at least four tablets in the tablet group 410 contacts the deformable portion 330 in the second state.

[0073] In this implementation, since at least four flat plates are in contact with the deformed portion 330 in the second state, the shape of the deformed portion 330 can be stably in the second state; at this time, since at least four flat plates are in contact with the deformed portion 330 in the second state, the deformed portion 330 in the second state can be prevented from being damaged due to excessive deformation when encountering a large impact force. As an example, a user walks with an electronic device in the second device posture, and the electronic device in the second device posture falls to the ground. At this time, the electronic device in the second device posture will have a large impact force with the ground. At this time, since at least four flat plates are in contact with the deformed portion 330 in the second state, at least four flat plates can offset or absorb the impact force at the deformed portion 330 in the second state, thereby preventing the deformed portion 330 in the second state from shaking and deforming significantly due to the impact force.

[0074] Of course, in other implementations, only some of the at least four plates in the plate group 410 may be in contact with the deformed portion 330 in the second state, and the remaining plates in the at least four plates in the plate group 410 may also have a small gap with the deformed portion 330 in the second state. In this case, since the gap between the remaining plates and the deformed portion 330 in the second state is small, the deformed portion 330 in the second state can be prevented from being greatly shaken and deformed due to the impact force. As an example, two plates in the plate group 410 are in contact with the deformed portion 330 in the second state, and the other two plates in the plate group 410 have a small gap with the deformed portion 330 in the second state.

[0075] In this implementation, the flat panel group 410 may include at least: a first flat panel group and a second flat panel group. The first flat panel group may include at least two first flat panels 411; the second flat panel group may include at least two second flat panels 412; wherein the first flat panel 411 is rotatably connected to the second flat panel 412; since the first flat panel 411 is rotatably connected to the second flat panel 412, at this time, if the electronic device changes between the first device posture and the second device posture, there will be force transmission between the first flat panel 411 and the second flat panel 412, so that the first flat panel 411 and the second flat panel 412 can move simultaneously on the corresponding motion track, so as to simultaneously adapt to the deformation of the deformation part 330 and reduce the distance between the flat panel and the deformation part 330.

[0076] The number of the first plates 411 is not limited. For example, the first plate group may include two first plates 411. The number of the second plates 412 is not limited. For example, the second plate group may include two second plates 412.

[0077] The relative positional relationship between the first flat plate 411 and the second flat plate 412 is not limited. For example, the two second flat plates 412 are located between the two first flat plates 411. At this time, the two first flat plates 411 are located close to the body side, and the two second flat plates 412 are located away from the body side. As an example, one of the two first flat plates 411 is arranged adjacent to the first body 100, the other of the two first flat plates 411 is arranged adjacent to the second body 200, and the two second flat plates 412 are arranged adjacent to each other, so that the screen 300 is jointly supported by the first body 100, one first flat plate 411, one second flat plate 412, another second flat plate 412, another first flat plate 411 and the second body 200 arranged in parallel. For another example, the two first flat plates 411 are located between the two second flat plates 412. At this time, the two second flat plates 412 are located close to the main body, and the two first flat plates 411 are located away from the main body. As an example, one of the two second flat plates 412 is arranged adjacent to the first body 100, and the other of the two second flat plates 412 is arranged adjacent to the second body 200. The two first flat plates 411 are arranged adjacent to each other, so that the screen 300 is jointly supported by the first body 100, one second flat plate 412, one first flat plate 411, another first flat plate 411, another second flat plate 412 and the second body 200 arranged in parallel.

[0078] In this implementation, if the flat plate group 410 forms a polygonal space, the rotational connection between the first flat plate 411 and the second flat plate 412 corresponds to the tangent point of the arc surface of the deformed portion 330 in the second state, so that both the first flat plate 411 and the second flat plate 412 can stabilize the shape of the deformed portion 330 in the second state.

[0079] Here, the portion of the deformed portion 330 in the second state defined by the first plate 411 and the portion of the deformed portion 330 in the second state defined by the second plate 412 are located on opposite sides of the first plane K, so that the shape of the deformed portion 330 in the second state is stable. The first plane K is the plane where the maximum thickness dimension of the deformed portion 330 in the second state is located. Figure 7 Here, the first plane K is perpendicular to the axis of rotation.

[0080] As an example, the contact portion between the first plate 411 and the deformed portion 330 in the second state and the contact portion between the second plate 412 and the deformed portion 330 in the second state are located on opposite sides of the first plane K. As another example, the contact portion between the first plate 411 and the deformed portion 330 in the second state and the portion with the smallest distance between the second plate 412 and the deformed portion 330 in the second state are located on opposite sides of the first plane K. As another example, the portion with the smallest distance between the first plate 411 and the deformed portion 330 in the second state and the portion with the smallest distance between the second plate 412 and the deformed portion 330 in the second state are located on opposite sides of the first plane K.

[0081] In this implementation, if the flat plate group 410 forms a polygonal space, the first flat plate group provides a deformation force so that the deformed portion 330 is in the second state, and the second flat plate group provides protection for the deformed portion 330 in the second state. At this time, the second flat plate group does not provide a deformation force for the deformed portion 330 in the second state. The second flat plate group and the deformed portion 330 in the second state may be in contact or may have only a small gap, so that the second flat plate group is only used to stabilize the shape of the deformed portion 330 in the second state and prevent the deformed portion 330 in the second state from being greatly deformed or shaking with a large displacement under the impact force.

[0082] Here, the first flat panel group is located near the body side, and the second flat panel group is located away from the body side. For example, the first flat panel group may include two first flat panels 411, and the second flat panel group may include two second flat panels 412, one of the two first flat panels 411 is disposed adjacent to the first body 100, the other of the two first flat panels 411 is disposed adjacent to the second body 200, and the two second flat panels 412 are disposed between the two first flat panels 411 and adjacent to each other; at this time, if the flat panel group 410 forms a polygonal space, the deformed portion 330 in the second state is in a folded shape, and in order to transform the deformed portion 330 in the first state from a flat shape to a folded shape, the two first flat panels 411 adjacent to the body will provide a deformation force to the deformed portion so that the deformation force forms a folded second state; here, since the deformed portion has formed a folded second state based on the deformation force provided by the first flat panel 411, the second flat panel 412 only needs to stabilize the shape of the deformed portion in the second state to prevent the shape of the deformed portion in the second state from being unstable and shaking when the electronic device falls, and the second flat panel 412 no longer needs to provide a deformation force to the deformed portion in the second state to reduce the force point of the deformed portion in the second state.

[0083] Of course, in other implementation examples, the second flat plate group can also provide protection for the deformed portion 330 in the second state and provide a smaller deformation force for the deformed portion 330 in the second state so that the deformed portion 330 in the second state can reach a set shape.

[0084] Of course, in other examples, if the flat panel group 410 forms a polygonal space, the first flat panel group and the second flat panel group can both provide protection for the deformed portion 330 in the second state. At this time, neither the first flat panel group nor the second flat panel group provides deformation force to the deformed portion 330 in the second state. In the second device posture, the first part 310 and the second part 320 of the screen 300 are stacked together based on the first body 100 and the second body 200. At this time, the deformed portion 330 of the screen 300 can naturally form a shape based on the relative position relationship between the first part 310 and the second part 320 of the screen 300. This shape can be the same as the shape of the deformed portion 330 in the second state. At this time, external force is no longer required to deform the deformed portion 330 again. It is only necessary to provide protection for the deformed portion 330 in the second state through the first flat panel group and the second flat panel group.

[0085] Here, the first flat panel group and the second flat panel group may both be in contact with the deformable portion 330 without providing a deforming force. When the electronic device falls, the first flat panel group and the second flat panel group may jointly absorb or offset the impact force at the deformable portion 330. The first flat panel group and the second flat panel group may both have a small gap with the deformable portion 330. When the electronic device falls, the first flat panel group and the second flat panel 412 may jointly absorb or offset most of the impact force at the deformable portion 330, thereby preventing the deformable portion 330 from deforming with a large displacement. Of course, only one of the first flat panel group and the second flat panel group may be in contact with the deformable portion 330 without providing a deforming force, and the other may have a small gap with the deformable portion 330.

[0086] In this implementation, the connection device 400 may further include: a control group 420, which corresponds to the flat panel group 410, so that each flat panel in the flat panel group 410 switches between the flat surface and the accommodating space based on the corresponding motion track of each flat panel.

[0087] The structure of the control group 420 is not limited, as long as the control group 420 can enable each tablet in the tablet group 410 to switch between the flat surface and the accommodating space based on the corresponding motion track of each tablet when the electronic device changes between the first device posture and the second device posture.

[0088] For example, the control group 420 includes: a first group of motion tracks, a first group of motion components cooperating with the first group of motion tracks, a second group of motion tracks, a second group of motion components cooperating with the second group of motion tracks, a first group of guide tracks and at least two rotating arms.

[0089] The first group of motion tracks may include at least two first motion tracks 421, the first motion tracks 421 are fixed to the first flat plate 411, the first motion tracks 421 and the deformation part 330 are located on the two opposite sides of the first flat plate 411; the surface of one side of the first flat plate 411 is used to support the deformation part 330 of the screen 300, and the first motion track 421 on the other side of the first flat plate 411 is used to define the motion track of the first flat plate 411, and the first group of motion components includes at least two first motion elements 423; the at least two first motion elements 423 are arranged on at least two There are synchronous arm bodies, at least one first synchronous arm body 431 of at least two synchronous arm bodies can be translatedly arranged on the first fixed arm body 441; at least one second synchronous arm body 432 of at least two synchronous arm bodies can be translatedly arranged on the second fixed arm body 442; the first fixed arm body 441 is fixed to the first body 100; the second fixed arm body 442 is fixed to the second body 200; through the cooperation of the first moving element 423 and the first moving track 421, the first plate 411 can move based on the first moving track 421 and adapt to the deformation of the deformation part 330.

[0090] Here, at least one first moving track 421 is fixed to the other side of each first flat plate 411 .

[0091] Here, the distance between the end of the first moving track 421 close to the fixed body 401 and the first flat plate 411 is smaller than the distance between the end of the first moving track 421 away from the fixed body 401 and the first flat plate 411; so that in the process of the electronic device switching from the first device posture to the second device posture, the first flat plate 411 moves along the first direction away from the fixed body 401 and moves away from the deformation part 330, thereby providing a larger space for the deformation part 330 to accommodate the deformation of the deformation part 330 and prevent the deformation part 330 from being crushed.

[0092] Here, the shape of the first moving track 421 is not limited. Figure 2 and Figure 4 As shown, the first motion track 421 may be an arc track. In this case, the first plate 411 can move more smoothly based on the first motion track 421. As an example, the first motion track 421 is a non-circular arc track. In one application, the first motion track 421 is an elliptical arc track. For another example, Figure 5 As shown, the first moving track 421 may be a straight track.

[0093] Here, each synchronization arm body is provided with at least one first motion element 423 , that is, the first synchronization arm body 431 is provided with at least one first motion element 423 , and the second synchronization arm body 432 is provided with at least one first motion element 423 .

[0094] Here, since the first fixed arm body 441 is fixed to the first body 100, and the second fixed arm body 442 is fixed to the second body 200; when the first body 100 and the second body 200 rotate relative to each other, the first fixed arm body 441 and the second fixed arm body 442 rotate relative to each other, the first fixed arm body 441 pushes the first synchronous arm body 431 to rotate, and the second fixed arm body 442 pushes the second synchronous arm body 432 to rotate, the first moving element 423 on the first fixed arm body 441 and the first moving element 423 on the second fixed arm body 442 slide in the first moving track 421 respectively, so as to drive the first plate 411 to move based on the first moving track 421.

[0095] Here, the shape of the first moving element 423 is not limited. For example, the first moving element 423 can slide in the first moving track 421 and can rotate in the first moving track 421. As an example, the first moving element 423 can be a columnar structure, so that the first moving element 423 can slide smoothly in the first moving track 421 and can rotate in the first moving track 421. The first moving element 423 can be fixed to the synchronization arm body by bonding, welding, etc.; of course, the first moving element 423 and the synchronization arm body can also be different parts of the same structural member. For example, the first moving element 423 and the synchronization arm body can be formed into an integral structure by injection molding.

[0096] Here, the first synchronous arm body 431 can be arranged on the first fixed arm body 441 in a translational manner through a slide rail and a slideway. Figure 2 and Figure 4 As shown, the first synchronous arm body 431 is provided with a first slideway 4411, and a part of the first synchronous arm body 431 is inserted into the first slideway 4411, so that the first synchronous arm body 431 can be arranged on the first fixed arm body 441 in a translational manner. The second synchronous arm body 432 can be arranged on the second fixed arm body 442 in a translational manner through the slide rail and the slideway, as shown in FIG. Figure 2 As shown, the second synchronous arm body 432 is provided with a second slideway 4421 , and part of the second synchronous arm body 432 is inserted into the second slideway 4421 , so that the second synchronous arm body 432 can be arranged on the second fixed arm body 442 in a translational manner.

[0097] Here, the first fixed arm 441 and the first body 100 can be fixedly connected by bonding, clamping, or a threaded structure, and the second fixed arm 442 and the second body 200 can be fixedly connected by bonding, clamping, or a threaded structure.

[0098] The second group of motion tracks includes at least two second motion tracks 422, and the second motion tracks 422 and the deformation part 330 are located on the opposite sides of the second plate 412: the first group of second motion tracks 422 and the second group of second motion tracks 422 of the at least two second motion tracks 422 are arranged at intervals on the fixed body 401 along the first direction; the first synchronization arm body 431 and the second synchronization arm body 432 are located on the opposite sides of the fixed body 401 in the first direction, and are rotatably connected to the fixed body 401 respectively; the surface of one side of the second plate 412 is used to support the deformation part 330 of the screen 300, and the second motion track 422 on the other side of the second plate 412 is used to define the motion track of the second plate 412; the second group of motion components includes at least two second motion elements 424, and the second motion elements 424 are fixed to the second plate 412. The second motion element 424 cooperates with the second motion track 422 to enable the second plate 412 to move based on the second motion track 422 and adapt to the deformation of the deformation part 330.

[0099] It should be noted that the first plate 411 is rotationally connected to the second plate 412. At this time, the second plate 412 can rotate relative to the first plate 411, and the position of the rotation center of the second plate 412 is determined; the angle of rotation of the second plate 412 relative to the first plate 411 is determined by the cooperation of the second motion element 424 and the second motion track 422, that is, the first plate 411 and the second plate 412 are rotationally connected to define the rotation axis of the second plate 412, and the second motion element 424 and the second motion track 422 cooperate to define the rotation angle of the second plate 412 relative to the rotation axis; The second moving element 424 cooperates with the second moving track 422 to enable the second plate 412 to move along a determined trajectory, so that during the movement of the first body 100 relative to the second body 200, the second plate 412 and the deformation portion 330 can have a stable relative position relationship. For example, during the movement of the first body 100 relative to the second body 200, the distance between the second plate 412 and the deformation portion 330 is less than a first set value. At this time, the first set value satisfies that the second plate 412 and the deformation portion 330 are just in contact or there is a small gap between the second plate 412 and the deformation portion 330.

[0100] The first group of the at least two second moving tracks 422 corresponds to the second plate 412 on the first body 100 side, and the second group of the at least two second moving tracks 422 corresponds to the second plate 412 on the second body 200 side. The first synchronization arm body 431 and the second synchronization arm body 432 can be rotatably connected to the fixed body 401 through a rotating shaft structure.

[0101] Here, since the first group of second motion tracks 422 and the second group of second motion tracks 422 of the at least two second motion tracks 422 are arranged on the fixed body 401 at intervals along the first direction; at this time, the first group of second motion tracks 422 and the second group of second motion tracks 422 can be opened on the fixed body 401, and the first group of second motion tracks 422 and the second group of second motion tracks 422 can be synchronously processed and formed, so as to ensure the relative position relationship between the first group of second motion tracks 422 and the second group of second motion tracks 422. At this time, the accuracy of the relative position relationship between the second plate 412 based on the movement of the first group of second motion tracks 422 and the second plate 412 based on the movement of the second group of second motion tracks 422 can also be improved, so that in the first device posture, the two second plates 412 can be flatter to reduce the height difference between the two second plates 412.

[0102] Here, if Figure 2 and Figure 5 As shown, the distance between the end of the second moving track 422 close to the first plate and the second plate 412 is smaller than the distance between the end of the second moving track 422 far from the first plate and the second plate 412; so that in the process of switching the electronic device from the first device posture to the second device posture, the second plate 412 moves both along the first direction away from the fixed body 401 and towards the side close to the deformed portion 330, so that the second plate 412 can adapt to the shape of the deformed portion 330, reduce the distance between the second plate 412 and the deformed portion 330, and provide protection for the deformed portion 330 in the second state through the second plate group. It should be noted that when the electronic device switches from the first device posture to the second device posture, since the first plate 411 drives the second plate 412 to move a certain distance away from the deformed portion 330, at this time, the end of the second plate 412 away from the first plate 411 needs to move towards the side close to the deformed portion 330, so that the rotation connection between the first plate 411 and the second plate 412 corresponds to the tangent point of the arc surface of the deformed portion 330 in the second state.

[0103] Here, the shape of the second motion track 422 is not limited. Figure 2 and Figure 4 As shown, the second motion track 422 may be an arc track. In this case, the second plate 412 can move more smoothly based on the second motion track 422. As an example, the second motion track 422 is a non-circular arc track. In one application, the second motion track 422 is an elliptical arc track. For another example, Figure 5 As shown, the second motion track 422 may be a straight track. Figure 2 and Figure 3As shown, the first direction N1 is perpendicular to the rotation axis. The rotation axis refers to the axis of relative rotation of the first body 100 and the second body 200. The first group of first motion tracks 421, a first plate 411, the first group of second motion tracks 422, a second plate 412, the first synchronization arm 431 and the first fixed arm 441 are located on the first body 100 side, and the second group of first motion tracks 421, another first plate 411, the second group of second motion tracks 422, another second plate 412, the second synchronization arm 432 and the second fixed arm 442 are located on the second body 200 side, so that during the rotation of the first body 100 relative to the second body 200, the first plate 411, the second plate 412, the first synchronization arm 431, the first fixed arm 441 and the first body 100 move relative to the fixed body 401, and at the same time, the other first plate 411, the other second plate 412, the second synchronization arm 432, the second fixed arm 442 and the second body 200 move relative to the fixed body 401.

[0104] Here, the shape of the second moving element 424 is not limited. For example, the second moving element 424 can be both able to slide in the second moving track 422 and to rotate in the second moving track 422. As an example, the second moving element 424 can be a columnar structure, so that the second moving element 424 can both slide smoothly in the second moving track 422 and rotate in the second moving track 422. The second moving element 424 can be fixed to the second plate 412 by bonding, welding, etc.; of course, the second moving element 424 and the second plate 412 can also be different parts of the same structural member. For example, the second moving element 424 and the second plate 412 can be formed into an integral structure by injection molding.

[0105] The first group of guide rails includes at least two first guide rails, and the first guide rails and the deformed portion 330 are located on the opposite sides of the second flat plate 412; the first group of first guide rails 451 and the second group of first guide rails 452 of the at least two first guide rails are arranged at intervals along the first direction on the fixed body 401. The first end of the first rotating arm body 461 of the at least two rotating arm bodies cooperates with the first group of first guide rails 451, and the second end of the first rotating arm body 461 is rotatably arranged on the first fixed arm body 441; the first end of the second rotating arm body 462 of the at least two rotating arm bodies cooperates with the second group of first guide rails 452, and the second end of the second rotating arm body 462 is rotatably arranged on the second fixed arm body 442, so as to provide a guiding effect for the relative movement of the first fixed arm body 441 and the second fixed arm body 442 through the cooperation of the first guide rails and the rotating arm body.

[0106] Here, the shape of the first guide track is not limited. For example, the first guide track is an arc track. As an example, the first guide track can be a circular arc track.

[0107] Here, the shape of the first end of the first rotating arm body 461 is not limited. For example, the first end of the first rotating arm body 461 is arc-shaped. As an example, the first end of the first rotating arm body 461 is arc-shaped. When the first end of the arc-shaped first rotating arm body 461 is inserted into the arc-shaped first guide track, the first fixed arm body 441 is rotatably connected to the fixing member.

[0108] Here, the shape of the first end of the second rotating arm body 462 is not limited. For example, the first end of the second rotating arm body 462 is arc-shaped. As an example, the first end of the second rotating arm body 462 is arc-shaped. When the first end of the arc-shaped second rotating arm body 462 is inserted into the arc-shaped first guide track, the second fixed arm body 442 is rotatably connected to the fixing member.

[0109] During the movement of the first body 100 relative to the second body 200, the first fixed arm 441 and the second fixed arm 442 move relative to each other, the first end of the first rotating arm 461 slides in the first group of first guide rails 451, and the second end of the first rotating arm 461 adaptively rotates relative to the first fixed wall, the first end of the second rotating arm 462 slides in the second group of first guide rails 452, and the second end of the second rotating arm 462 adaptively rotates relative to the second fixed wall. At this time, the first fixed arm 441 and the second fixed arm 442 move relative to the fixed body 401 based on the trajectory defined by the first guide rail.

[0110] In this implementation, the control group 420 may also include: a second group of guide rails and a guide assembly that cooperates with the second group of guide rails. Through the cooperation of the guide assembly and the second group of guide rails, the motion trajectory of the first flat plate 411 can be further limited, so that the first flat plate 411 has a more stable motion trajectory.

[0111] The second group of guide rails may include at least two second guide rails, and the second guide rails and the deformation part 330 are located on the back sides of the first flat plate 411: the first group of second guide rails 453 of the at least two second guide rails are arranged on the first fixed arm body 441, and the second group of second guide rails 454 of the at least two second guide rails are arranged on the second fixed arm body 442.

[0112] Here, the surface of one side of the first plate 411 is used to support the deformed portion 330 of the screen 300, and the first moving track 421 and the second guide track on the other side of the first plate 411 are used together to define the moving track of the first plate 411 to make the moving track of the first plate 411 more stable.

[0113] Here, the distance between the end of the second guide rail close to the fixed body 401 and the first flat plate 411 is smaller than the distance between the end of the second guide rail away from the fixed body 401 and the first flat plate 411; so that in the process of the electronic device switching from the first device posture to the second device posture, the first flat plate 411 moves along the first direction away from the fixed body 401 and moves away from the deformation part 330, thereby providing a larger space for the deformation part 330 to accommodate the deformation of the deformation part 330 and prevent the deformation part 330 from being crushed.

[0114] Here, at least one second guide rail is fixed to the other side of each first flat plate 411 .

[0115] Here, the shape of the second motion track 422 is not limited. For example, the second guide track can be an arc track. As an example, Figure 2 and Figure 4 As shown, the second guide track may be an arc-shaped track, so that the first plate 411 moves along a determined track relative to the fixed arm body, thereby ensuring the smooth movement of the first plate 411 .

[0116] Here, if Figure 2 and Figure 4 As shown, the first set of second guide rails 453 can be directly opened on the first fixed arm body 441, and the second set of second guide rails 454 can be directly opened on the second fixed arm body 442. Of course, the first set of second guide rails 453 can also be opened on the structural member on the first fixed arm body 441, and the second set of second guide rails 454 can also be opened on the structural member on the second fixed arm body 442.

[0117] The guide assembly includes at least two guide members 455, which can be fixed to the first plate 411 by bonding or welding, or can be different parts of a structural member. A guide member 455 is fixedly provided on the other side of each first plate 411. The guide member 455 is inserted into the corresponding second guide rail to achieve the matching between the guide assembly and the second set of guide rails.

[0118] The shape of the guide member 455 is not limited. For example, the guide member 455 may be arc-shaped, so that the guide member 455 is inserted into the second guide track to provide a stable motion track for the first plate 411. As an example, the guide member 455 may be arc-shaped.

[0119] The second guide track is an arc-shaped track. When the guide member 455 is in an arc shape, the first plate 411 is rotatably connected to the fixed arm body. At this time, the first plate 411 can rotate relative to the fixed arm body, and the position of the rotation center of the first plate 411 is determined; the first moving element 423 cooperates with the first moving track 421 to determine the rotation angle of the first plate 411 relative to the fixed arm, that is, the axis of the second guide track is the rotation axis of the first plate 411, and the first moving element 423 cooperates with the first moving track 421 to limit the rotation angle of the first plate 411 relative to the rotation axis; the first moving element 423 cooperates with the first moving track 421 The first plate 411 can be made to move along a certain trajectory, so that during the movement of the first body 100 relative to the second body 200, the first plate 411 and the deformation portion 330 can have a stable relative position relationship. For example, during the movement of the first body 100 relative to the second body 200, the distance between the second plate 412 and the deformation portion 330 is less than a second set value. At this time, the second set value satisfies that the first plate 411 and the deformation portion 330 are just in contact, or the second set value satisfies that there is a small gap between the first plate 411 and the deformation portion 330, or the second set value satisfies that the first plate 411 provides a deformation force for the deformation portion 330.

[0120] In this implementation, during the rotation of the first body 100 relative to the second body 200, the first body 100 moves relative to the second body 200 along a trajectory defined by the first set of guide rails, the first plate moves along a trajectory jointly defined by the first set of motion rails and the second set of guide rails, and the second plate moves along a trajectory defined by the second set of motion rails.

[0121] like Figure 3 and Figure 4As shown, the electronic device is in the process of switching from a first device posture to a second device posture. When the first body 100 rotates relative to the second body 200, the first body 100 rotates relative to the fixed body 401 along the first group of first guide rails 451 through the first rotating arm body 461, and moves away from the fixed body 401. The first body 100 drives the first synchronous arm body 431 to move together through the first fixed arm body 441. The first synchronous arm body 431 moves both relative to the first body 100 and relative to the fixed body 401. The first plate 411 moves based on the sliding of the guide member 455 in the first group of second guide rails 453 on the first fixed arm body 441 and the movement of the first moving element 423 on the first synchronous arm body 431 in the first group of first moving rails 421. Since the first plate 411 and the second plate 412 are rotatably connected, the first plate 411 simultaneously drives the second plate 412 to move away from the fixed body 401. At the same time, the second plate 412 rotates relative to the first body 100 and moves based on the movement of the second moving element 424 in the first group of second moving rails 422. Here, the first plate 411 and the second plate 412 are both located on the side of the first body 100. Here, the movement on the side of the second body 200 is similar. When the first body 100 rotates relative to the second body 200, the second body 200 rotates relative to the fixed body 401 along the second group of first guide rails 452 through the second rotating arm body 462 and moves away from the fixed body 401. The second body 200 drives the second synchronous arm body 432 to move together through the second fixed arm body 442. The second synchronous arm body 432 not only moves relative to the second body 200 but also rotates relative to the fixed body 401. The first plate 411 is based on the guide member 455. The first plate 411 and the second plate 412 are rotatably connected to each other, and the first plate 411 drives the second plate 412 to move away from the fixed body 401. At the same time, the second plate 412 rotates relative to the first body 100 and moves based on the movement of the second moving element 424 in the second group of second moving tracks 422. Here, the first plate 411 and the second plate 412 are both located on the second body 200 side.

[0122] During the process of the electronic device switching from the second device posture to the first device posture, the movement process of the first body 100 and the second body 200 is similar to the process of the electronic device switching from the first device posture to the second device posture, which will not be repeated here. Of course, the control group 420 may also not include: the second group of guide rails and guide components. In this case, the first flat plate 411 moves based on the trajectory defined by the first group of motion components and the first motion rail 421. Alternatively, the control group 420 may also not include the first group of motion rails and the first group of motion components. In this case, the first flat plate 411 can move based on the trajectory defined by the second group of guide rails and guide components.

[0123] When the control group 420 includes a first set of motion tracks and a second set of guide tracks, the motion trajectories of the first plate 411 and the second plate 412 are determined so that the first plate 411 and the second plate 412 can always be stably in a suitable position to protect the deformation part 330 during the switching process from the first device posture and the second device posture.

[0124] Figure 6The control group 420 includes a first group of motion tracks and a second group of guide tracks, wherein A is a rotatable rotation pair of the first synchronous arm body 431 and the fixed body 401, E is a slidable sliding pair of the first synchronous arm body 431 and the first plate 411 through the first motion track 421 and the first motion element 423, where the first motion element 423 can both translate and rotate in the first motion track 421; B is a rotatable rotation pair of the first rotating arm body 461 and the fixed body 401, and C is a rotatable rotation pair of the first rotating arm body 461 and the first fixed body 401. The arm body 441 is a rotatable rotating pair, D is a translation pair that can connect the first synchronous arm body 431 and the first fixed arm body 441 translationally, F is a rotation pair that can connect the first plate 411 and the first fixed arm body 441 rotationally, G is a rotation pair that rotationally connects the first plate 411 and the second plate 412, and H is a sliding pair that slides the second plate 412 and the fixed body 401 through the first group of second moving tracks 422 and the second moving element 424. Here, the second moving element 424 can both translate and rotate in the second moving track 422. Here, the degrees of freedom of movement of the control group 420 are: F=3×N-2×Pl-1×Ph=3×5-2×6-1×2=1, N is the number of structural parts, the structural parts are the first synchronous arm body 431, the first plate 411, the second plate 412, the first fixed arm body 441 and the first steering arm body, a total of 5 structural parts, Pl is the number of low pairs, P1 is the A rotation pair, B rotation pair, C rotation pair, D translation pair, F rotation pair and G rotation pair, a total of 6 low pairs, Ph is the number of high pairs, Ph is the sliding pair at E and the sliding pair at H, a total of 2 high pairs; since the control group 420 has only one degree of freedom, at this time, the first plate 411 and the second plate 412 both have a determined motion trajectory.

[0125] Here, when the user flips the first body, when the first fixed arm body 441 has power input for flipping movement based on the first body, the first fixed arm body 441 drives the first synchronous arm body 431 to rotate around the rotation center A of the first synchronous arm body 431 during the flipping process; the first plate 411 and the first fixed arm body 441 are hinged together by the rotating pair F, so the rotation of the first fixed arm body 441 will also drive the first plate 411 to rotate, and the first plate 411 and the first synchronous arm body 431 have a slidable high pair E between the first motion track 421 and the first motion element 423, and the EF line determines the deflection movement of the first plate 411; the second plate 412 is hinged together with the first plate 411 by the rotating pair G, so the rotation of the first plate 411 will transmit power to the second plate 412, and the second plate 412 and the fixed body 401 have a sliding high pair H through the first group of second motion tracks 422 and the second motion element 424, and the GH line determines the deflection movement of the second plate 412. In summary, the entire movement is driven by the user's flipping, and because the system degree of freedom is 1, the movement form is unique and will not conflict with each other. The movement of the first plate 411 is driven by the movement of the first fixed arm 441 and the first synchronous arm 431, and the movement of the second plate 412 is driven by the first plate 411.

[0126] In some optional implementations of the embodiments of the present application, the connecting device 400 may further include: a control group 420 and a damping group. The control group 420 corresponds to the plate group 410, so that the plate group 410 can be adaptively moved by the control group 420 during the movement of the first body 100 relative to the second body 200; the damping group and the plate group 410 are spaced apart, and the damping group and the control group 420 are spaced apart in the axial direction, so that the damping group provides a damping force for the relative movement of the first body 100 and the second body 200, and the damping group does not affect the movement of the plate group 410.

[0127] Of course, in other implementations, the connecting device 400 may not include a damping group. In this case, the damping force of the movement of the first body 100 relative to the second body 200 may also be provided by the control group 420. For example, a damping structure is set between the first motion track 421 and the first motion element 423. For another example, a damping structure is set between the second motion track 422 and the second motion element 424. For another example, a damping structure is set between the first guide track and the rotating arm body. For another example, a damping structure is set between the second guide track and the guide assembly. Here, the form of the damping structure is not limited. For example, the damping structure may include a deformable thin elastic sheet. For another example, the damping structure may include friction protrusions.

[0128] In this implementation, the control group 420 has been described in the above embodiment and will not be repeated here.

[0129] In this implementation, the structure of the damping group is not limited, as long as it can provide damping force and does not affect the movement of the control group 420.

[0130] For example, the damping group may include: a rotating shaft assembly, a first connecting member, and a second connecting member. The rotating shaft assembly may include: at least two connecting shafts; adjacent connecting shafts of the at least two connecting shafts are rotatably connected; at this time, when the first body 100 rotates relative to the second body 200, the angle change between the first body 100 and the second body 200 can be accommodated by the relative rotation of the adjacent connecting shafts.

[0131] Two adjacent connecting shafts can be respectively fixed with gears, and the adjacent gears are meshed so that the adjacent connecting shafts can be matched and connected through the gear set. At this time, the meshed gears can also provide damping force for the relative rotation of the adjacent connecting shafts. Of course, damping plates can also be provided on the adjacent connecting shafts so that the damping plates on the connecting shafts can provide damping force for the relative rotation of the rotating shaft assembly.

[0132] The number of connecting shafts of the rotating shaft assembly is not limited. For example, the rotating shaft assembly may include four connecting shafts. For another example, the rotating shaft assembly may include six connecting shafts.

[0133] The first end of the first connecting member can be cooperatively connected to the first connecting shaft on the first side of the at least two connecting shafts, or can be fixedly connected, so that the first connecting member can drive the first connecting shaft to rotate; the second end of the first connecting member can be slidably set on the first fixed arm body 441, and the first fixed arm body 441 is fixed to the first body 100; the second end of the first connecting member can be slidably set on the first fixed arm body 441 through a slide structure or a slide rail structure, so that the second end of the first connecting member slides relative to the first fixed arm body 441 to adapt to the displacement of the first body 100 moving away from or close to the fixed body 401 during the relative movement of the first body 100 and the second body 200; that is, the displacement of the first body 100 moving away from or close to the fixed body 401 can be offset by the sliding of the second end of the first connecting member relative to the first fixed arm body 441.

[0134] The first end of the second connecting member can be cooperatively connected to the second connecting shaft on the second side of the at least two connecting shafts, or can be fixedly connected, so that the second connecting member can drive the second connecting shaft to rotate; the second end of the second connecting member can be slidably set on the second fixed arm body 442; the second fixed arm body 442 is fixed to the second body 200; the second end of the second connecting member can be slidably set on the second fixed arm body 442 through a slide structure or a slide rail structure, so that the second end of the second connecting member can slide relative to the second fixed arm body 442 to adapt to the displacement of the second body 200 moving away from or close to the fixed body 401 during the relative movement of the first body 100 and the second body 200; that is, the displacement of the second body 200 moving away from or close to the fixed body 401 can be offset by the sliding of the second end of the second connecting member relative to the second fixed arm body 442.

[0135] As an example, in the process of switching the electronic device from the first device posture to the second device posture. When the first body 100 rotates relative to the second body 200, the first body 100 rotates relative to the fixed body 401 along the first group of first guide rails 451 through the first rotating arm body 461, and moves away from the fixed body 401. The first body 100 drives the first synchronous arm body 431 and the first connecting member to move together through the first fixed arm body 441. The first connecting member not only slides relative to the first body 100 but also drives the first connecting shaft to rotate. The first connecting shaft drives the connecting shaft in the rotating assembly to rotate to provide damping force; the first synchronous arm body 431 not only translates relative to the first body 100 but also moves relative to the fixed arm body 441. The fixed body 401 rotates, and the first plate 411 moves based on the guide member 455 sliding in the first group of second guide tracks 453 on the first fixed arm body, and the first moving element 423 on the first synchronous arm body 431 moves in the first group of first moving tracks 421. Since the first plate 411 and the second plate 412 are rotatably connected, the first plate 411 simultaneously drives the second plate 412 to move away from the fixed body 401. At the same time, the second plate 412 rotates relative to the first plate 411 and moves based on the second moving element 424 moving in the first group of second moving tracks 422. Here, the first plate 411 and the second plate 412 are both located on the first body 100 side. Here, the movement of the second body 200 side is similar. When the first body 100 rotates relative to the second body 200, the second body 200 rotates relative to the fixed body 401 along the second group of first guide rails 452 through the second rotating arm body 462 and moves away from the fixed body 401. The second body 200 drives the second synchronous arm body 432 and the second connecting member to move together through the second fixed arm body 442. The second connecting member not only slides relative to the second body 200 but also drives the second connecting shaft to rotate. The second connecting shaft drives the connecting shaft in the rotating assembly to rotate to provide a damping force. The second synchronous arm body 432 is not only relative to the second body 200, but also drives the second connecting shaft to rotate. The first plate 411 moves based on the guide member 455 sliding in the second set of second guide tracks 454 on the second fixed arm 442 and the first moving element 423 on the second synchronous arm 432 moving in the second set of first moving tracks 421. Since the first plate 411 and the second plate 412 are rotatably connected, the first plate 411 simultaneously drives the second plate 412 to move away from the fixed body 401. At the same time, the second plate 412 rotates relative to the first plate 411 and moves based on the second moving element 424 moving in the second set of second moving tracks 422. Here, the first plate 411 and the second plate 412 are both located on the second body 200 side.

[0136] In the implementation, the number of the control group 420 and the damping group is not limited. For example, the connecting device 400 may include a set of plate groups 410 and two sets of control groups 420 and damping groups, wherein the set of plate groups 410 is disposed between the first body 100 and the second body 200, and the two sets of control groups 420 and damping groups are disposed between the first body 100 and the second body 200 at intervals along the axial direction.

For example, the flat panel group 410 can include the first flat panel group, the second flat panel group and the third flat panel group 410. The first flat panel group includes two first flat panels 411, the second flat panel group includes two second flat panels 412, and the third flat panel group 410 includes two third flat panels. A first flat panel 411, a second flat panel 412, a third flat panel, another third flat panel, another second flat panel 412, and another first flat panel 411 are arranged in parallel between the first body 100 and the second body 200. The two first flat panels 411 and the two second flat panels 412 are similar to the above-mentioned embodiments and are not repeated here. One of the two third flat panels can be rotatably connected to a second flat panel 412 through a rotating shaft structure, and the other third flat panel of the two third flat panels can be rotatably connected to another second flat panel 412 through a rotating shaft structure. The fixed body 401 may be provided with a first group of third motion tracks and a second group of third motion tracks at intervals along the first direction, and the two third plates may be fixed with third motion elements, which cooperate with the third motion tracks so that the two third plates can both rotate relative to the second plate and slide relative to the fixed body 401, so that the two third plates can move along a specific track to adapt to the deformation of the deformation portion 330. Here, the third motion track is similar to the second motion track, and the third motion element is similar to the second motion element 424, which will not be described in detail.
