[0059] In the embodiments of the present disclosure, Figures 1 to 4 As shown, the electronic device includes a first body 10, a second body 20, a deformable circuit board 40 and an adjustment mechanism 50. The second body 20 is rotatably connected to the first body 10 through a rotating connection structure 30; the first body 10 is in a first relative position relationship with respect to the second body 20, and the first surface of the first body 10 is parallel to the second surface of the second body 20; the first body 10 is in a second relative position relationship with respect to the second body 20, and the first surface of the first body 10 is stacked with the second surface of the second body 20. The first connection end of the circuit board 40 is connected to the first connection port of the first body 10, the second connection end of the circuit board 40 is connected to the second connection port of the second body 20, and the first deformation area 41 of the circuit board 40 is arranged opposite to the rotating connection structure 30. The adjustment mechanism 50 is arranged at the rotating connection structure 30; the adjustment mechanism 50 makes the first deformation area 41 form a first shape if the first body 10 satisfies the first relative position relationship with respect to the second body 20; if the first body 10 satisfies the second relative position relationship with respect to the second body 20, the first deformation area 41 forms a second shape, and the first shape is different from the second shape.

[0060] The electronic device disclosed in the present invention is an electronic device with a folding function, and the electronic device includes a tablet computer, a mobile phone, etc. The electronic device can switch between a flattened posture and a folded posture. Along the thickness direction of the first body 10, the first body 10 has a first surface and a third surface relative to each other, and along the thickness direction of the second body 20, the second body 20 has a second surface and a fourth surface relative to each other. The first body 10 and the second body 20 are rotated to be in a first relative position relationship, and the first surface of the first body 10 is parallel to the second surface of the second body 20, that is, the first surface and the second surface are coplanar, and the electronic device is in a flattened state. The first body 10 and the second body 20 are rotated to be in a second relative position relationship, and the first surface of the first body 10 is overlapped with the second surface of the second body 20, that is, the first surface and the second surface are in contact with each other or close to each other, and the electronic device is in a folded state.

[0061] The first body 10, the second body 20 and the rotating connection structure 30 are configured with a storage space for accommodating the circuit board 40. The circuit board 40 is a deformable circuit board 40. Along the length direction of the circuit board 40, the circuit board 40 has a first connection end and a second connection end relative to each other. The first body 10 is provided with a first connection port at one end away from the rotating connection structure 30, and the second body 20 is provided with a second connection port at one end away from the rotating connection structure 30. The first connection end of the circuit board 40 can be connected to the first connection port by screwing, and the second connection end of the circuit board 40 can be connected to the second connection port by screwing. For example, the first connection end is provided with a through hole, and the first connection port is a threaded hole. The screw is screwed into the through hole and the threaded hole to realize the connection between the first connection end and the first connection port.

[0062] A first gap channel is configured on one side of the rotating connection structure 30 close to the first body 10, and the circuit board 40 extends through the first gap channel toward the end of the first body 10. A second gap channel is configured on one side of the rotating connection structure 30 close to the second body 20, and the circuit board 40 extends through the second gap channel toward the end of the second body 20.

[0063] During the switching process of the electronic device from the flat state to the folded state, the circuit board 40 has a tendency to move toward the end of the first body 10 and the end of the second body 20, and the circuit board 40 moves slightly in the direction toward the end of the first body 10 and the end of the second body 20. During the switching process of the electronic device from the folded state to the flat state, the circuit board 40 has a tendency to move toward the rotating connection structure 30, and the circuit board 40 moves slightly in the direction toward the rotating connection structure 30.

[0064] When the electronic device switches between two postures, the components of the rotating connection structure 30 move relative to each other, and sufficient accommodation space needs to be provided at the rotating connection structure 30 to accommodate the circuit board 40. The larger the accommodation space, the larger the deformation of the corresponding circuit board 40. When the electronic device switches between two postures, the area on the circuit board 40 where the deformation is more obvious is the area near the rotating connection structure 30, and this area is defined as the first deformation area 41.

[0065] In the prior art, the rotating connection structure 30 is not provided with a control mechanism for controlling the deformation of the first deformation area 41 of the circuit board 40. When the electronic device is in a flattened state, the first deformation area 41 of the circuit board 40 is in a relaxed state; when the electronic device is in a folded state, the first deformation area 41 of the circuit board 40 is in a taut state. When the electronic device repeatedly switches between the two postures, the deformation of the first deformation area 41 is uncontrolled, and the local position of the first deformation area 41 will have a problem of excessive bending deformation, which will cause the first deformation area 41 to have problems such as line breakage and twisting, affecting the use of the circuit board 40.

[0066] The present disclosure provides an adjustment mechanism 50 to control the deformation of the circuit board 40 so that the first deformation area 41 can be maintained in the first shape or the second shape.

[0067] The electronic device is in a flattened state, the first body 10 and the second body 20 meet a first relative position relationship, and the adjustment mechanism 50 enables the first deformation area 41 to form a first shape. The first shape can be a combination of a plurality of straight sections and a plurality of arc sections, and the first shape is approximately wavy. The first shape enables the first deformation area 41 to be in a properly tensioned state, effectively avoiding the problem of excessive bending caused by a relaxed state.

[0068] The electronic device is in a folded state, the first body 10 and the second body 20 meet a second relative position relationship, and the adjustment mechanism 50 causes the first deformation area 41 to form a second shape. The second shape can be a combination of a straight section and two arc sections, the two arc sections are located on both sides of the straight section, and the second shape is approximately U-shaped. The second shape causes the first deformation area 41 to be in a taut state.

[0069] In this embodiment, an adjusting mechanism 50 is provided at the rotating connection structure 30. When the electronic device is in a flattened state, the adjusting mechanism 50 enables the first deformation region 41 of the circuit board 40 to form a first shape, and the first deformation region 41 is in a properly tensioned state, thereby effectively avoiding the problem of excessive bending caused by a relaxed state. When the electronic device is in a folded state, the adjusting mechanism 50 enables the first deformation region 41 to form a second shape, and the second shape enables the first deformation region 41 to be in a taut state. By controlling the shape of the first deformation region 41 through the adjusting mechanism 50, damage to the circuit board 40 can be effectively avoided, thereby ensuring the reliability of the use of the electronic device.

[0070] In the embodiments of the present disclosure, Figures 1 to 4 As shown, the electronic device further includes a deformable screen 60, a first area of ​​the screen 60 is connected to the first surface of the first body 10, a second area of ​​the screen 60 is connected to the second surface of the second body 20, and a second deformation area 61 of the screen 60 is arranged opposite to the rotating connection structure 30. The first body 10 is in a first relative position relationship with respect to the second body 20, and the second deformation area 61 forms a third shape, which is different from the first shape. The first body 10 is in a second relative position relationship with respect to the second body 20, and the second deformation area 61 forms a fourth shape, which is similar to the second shape.

[0071] Specifically, the screen 60 is a deformable screen 60, and the screen 60 is divided into three areas, namely a first area, a second area, and a second deformation area 61. The first area and the second area are areas where no deformation occurs, and the second deformation area 61 is located between the first area and the second area. The second deformation area 61 of the screen 60 is opposite to the first deformation area 41 of the circuit board 40.

[0072] like Figure 4As shown, according to the different shapes of the first deformation region 41 at different positions, the first deformation region 41 is divided into a first portion 411 and a second portion 412 and a third portion 413 located on both sides of the first portion 411. According to the different degrees of shape change at different positions of the second deformation region 61, the second deformation region 61 is divided into a fourth portion 611 and a fifth portion 612 and a sixth portion 613 located on both sides of the fourth portion 611. The first portion 411 is opposite to the fourth portion 611, the second portion 412 is opposite to the fifth portion 612, and the third portion 413 is opposite to the sixth portion 613.

[0073] The electronic device is in a flattened state, and the first portion 411 and the fourth portion 611 are nearly parallel. The first portion 411, the second portion 412, and the third portion 413 of the first deformation region 41 are approximately wavy line shapes, that is, the first shape is approximately wavy line shape. The fourth portion 611, the fifth portion 612, and the sixth portion 613 of the second deformation region 61 are all straight shapes, that is, the third shape is straight shape, and the third shape is different from the first shape.

[0074] The third shape is a straight shape, so that the flatness of the screen 60 meets the display requirements, and the first shape is approximately a wavy line shape, so that the circuit board 40 is in a suitable tension state.

[0075] When the electronic device is in the folded state, the first portion 411 of the first deformation region 41 is straight, the second portion 412 and the third portion 413 are arc-shaped, that is, the second shape is approximately U-shaped. The deformation amount of the fourth portion 611 of the second deformation region 61 is large, and the fourth portion 611 is approximately semicircular, while the deformation amounts of the fifth portion 612 and the sixth portion 613 are small, and the fifth portion 612 and the sixth portion 613 are arc-shaped from semicircular to straight, that is, the fourth shape is approximately water drop-shaped, and the fourth shape is similar to the second shape.

[0076] The fourth shape is approximately a water drop shape, ensuring that the first area and the second area of ​​the screen 60 can fit each other. The third shape is approximately a U shape, so that the bending shape of the first deformation area 41 can better adapt to the bending shape of the second deformation area 61, which is beneficial to reducing the overall occupied space of the first deformation area 41 and the second deformation area 61, making the structure compact.

[0077] In this embodiment, the adjusting mechanism 50 causes the first deformation area 41 to form a first shape, and at this time the second deformation area 61 of the screen 60 forms a third shape, the circuit board 40 is in a suitable tensioned state, and the flatness of the screen 60 meets the display requirements; the adjusting mechanism 50 causes the first deformation area 41 to form a second shape, and at this time the second deformation area 61 of the screen 60 forms a fourth shape. The second shape and the fourth shape are similar, which is beneficial to reducing the overall occupied space of the first deformation area 41 and the second deformation area 61, making the internal structure more compact.

[0078] In the embodiment of the present disclosure, if the first deformation region 41 forms a first shape, the first deformation region 41 is in a first constrained state; if the first deformation region 41 forms a second shape, the first deformation region 41 is in a second constrained state.

[0079] Specifically, the electronic device is in a flattened state, and the adjustment mechanism 50 causes the first deformation region 41 to form a first shape, and the first deformation region 41 is in a first constrained state. For example, the first deformation region 41 includes a first portion 411, a second portion 412, and a third portion 413, and the first portion 411, the second portion 412, and the third portion 413 are constrained by the adjustment mechanism 50, and the shapes of the three portions are relatively fixed.

[0080] For example, the adjustment mechanism 50 includes three adjustment members, one adjustment member controls the shape of the first part 411, one adjustment member controls the shape of the second part 412, and one adjustment member controls the shape of the third part 413. The cooperation of the three adjustment members makes the first shape of the first deformation area 41 under a controlled state, thereby effectively avoiding the problems of displacement or shaking of the first deformation area 41 during use, thereby facilitating the first deformation area 41 to smoothly transform from the first shape to the second shape when the electronic device switches between two postures.

[0081] The electronic device is in a folded state, and the adjustment mechanism 50 causes the first deformation region 41 to form a second shape. The first deformation region 41 is in a second constrained state, that is, the first part 411, the second part 412 and the third part 413 are constrained by the adjustment mechanism 50, and the shapes of the three parts are relatively fixed.

[0082] For example, the adjustment mechanism 50 includes three adjustment members, one adjustment member controls the shape of the first part 411, one adjustment member controls the shape of the second part 412, and one adjustment member controls the shape of the third part 413. The cooperation of the three adjustment members makes the second shape of the first deformation area 41 under control, thereby effectively preventing the first deformation area 41 from shifting, shaking, or colliding with other internal parts after the electronic device is folded, thereby facilitating the first deformation area 41 to smoothly transform from the second shape to the first shape when the electronic device switches between two postures.

[0083] In this embodiment, the first deformation region 41 forms a first shape, the first deformation region 41 is in a first constrained state, the first deformation region 41 forms a second shape, the first deformation region 41 is in a second constrained state, the first shape and the second shape are constrained by the adjustment mechanism 50, and the two shapes are relatively fixed, ensuring that the first deformation region 41 can stably maintain the first shape or the second shape when the electronic device is in a flattened state or a folded state, and at the same time, the first deformation region 41 can smoothly switch between the first shape and the second shape.

The first rotating component 31 is connected to the first body 10 and can move in a first rotating direction relative to the second body 20; the second rotating component 32 is connected to the second body 20 and can move in a second rotating direction relative to the first body 10, and the first rotating direction is different from the second rotating direction. The adjustment mechanism 50 is connected to the first rotating component 31 and the second rotating component 32. The adjustment mechanism 50 controls the circuit board 40 to move along a preset track with the movement of the first rotating component 31 and the second rotating component 32, so that the first deformation area 41 can be in the first constraint state or the second constraint state.

[0086] Specifically, the rotating connection structure 30 includes a mounting seat 33, a first rotating assembly 31 and a second rotating assembly 32, wherein the first rotating assembly 31 and the second rotating assembly 32 are mounted on the mounting seat 33. The mounting seat 33 has a first center plane and a second center plane, wherein the direction of the first center plane is parallel to the length direction of the mounting seat 33, and the direction of the second center plane is parallel to the width direction of the mounting seat 33. The first rotating assembly 31 and the second rotating assembly 32 are symmetrically arranged with respect to the first center plane of the mounting seat 33.

The first rotating component 31 and the second rotating component 32 rotate to drive the adjustment mechanism 50 to move, and the first deformation area 41 of the circuit board 40 switches between the first shape and the second shape with the movement of the adjustment mechanism 50. The adjustment mechanism 50 is driven to move by the rotation of the first rotating component 31 and the second rotating component 32, so that the shape switching of the first deformation area 41 of the circuit board 40 and the shape switching of the second deformation area 61 of the screen 60 are kept synchronous.

[0095] The second rotating assembly 32 includes two second rotating track assemblies 321 and two second torsion assemblies 322. The two second rotating track assemblies 321 are symmetrically arranged at the two ends of the second side of the mounting seat 33 with respect to the second center plane of the mounting seat 33, and the two second torsion assemblies 322 are symmetrically arranged at the two ends of the second side of the mounting seat 33 with respect to the second center plane of the mounting seat 33. A second track path of the second rotating track assembly 321 is constructed on the mounting seat 33.

The second rotating track assembly 321 is connected to the second body 20 to provide navigation of the motion track for the rotation of the second body 20. The second rotating track assembly 321 is connected to the second torsion assembly 322 through the second transmission arm.

[0097] The adjustment mechanism 50 can be connected to the first rotating shaft 3121 and the second rotating shaft 3221, and the rotation of the first rotating shaft 3121 and the second rotating shaft 3221 drives the adjustment mechanism 50 to perform linear motion and / or rotational motion, so that the first deformation area 41 of the circuit board 40 can move along a preset trajectory.

[0098] For example, the adjustment mechanism 50 performs linear motion, so that the first portion 411 of the first deformation region 41 moves in a direction toward or away from the fourth portion 611 of the second deformation region 61 , so as to control the shape of the first portion 411 .

[0099] For example, the adjustment mechanism 50 rotates so that the second part 412 of the first deformation area 41 moves along an arc-shaped trajectory path to control the shape of the second part 412; the adjustment mechanism 50 rotates so that the third part 413 of the first deformation area 41 moves along an arc-shaped trajectory path to control the shape of the third part 413.

[0100] The adjusting mechanism 50 is disposed in the area between the two first torsion assemblies 312 and the two second torsion assemblies 322. The adjusting mechanism 50 is connected to the two first torsion assemblies 312 and the two second torsion assemblies 322. The rotation of the four torsion assemblies drives the adjusting mechanism 50 to perform linear motion and / or rotational motion, so that the circuit board 40 can move along a preset trajectory to control the first shape and the second shape of the circuit board 40, while rationally utilizing the internal space of the electronic device to ensure the miniaturization of the electronic device.

[0101] In the embodiments of the present disclosure, Figures 5 to 11 As shown, the adjustment mechanism 50 includes a rotating connection component 51, a guide component 52, a lifting plate 53 and a movable connection component 54.

[0102] Specifically, the rotating connection assembly 51 includes a first rotating shaft 511 and a second rotating shaft 512. The two ends of the first rotating shaft 511 are respectively connected to the two first rotating shafts 3121 of the two first torsion assemblies 312, and the first rotating shaft 511 rotates synchronously with the two first rotating shafts 3121.

[0103] The guide assembly 52 includes a first guide member and a second guide member that are spaced apart, and the first guide member and the second guide member can both be guide wheels. The first guide wheel 521 is sleeved on the first rotating shaft 511, and the first guide wheel 521 and the first rotating shaft 511 are clearance-matched, and the first guide wheel 521 and the first rotating shaft 511 rotate asynchronously.

The length of the second guide wheel 522 is slightly shorter than the length of the second rotating shaft 512.

[0104] Along the width direction of the lifting plate 53, one side of the lifting plate 53 is connected to the first rotating shaft 511 through a first movable connecting member, and the other side of the lifting plate 53 is connected to the second rotating shaft 512 through a second movable connecting member. The first movable connecting member and the second movable connecting member have the same structure.

[0105] The first movable connecting member includes a first connecting rod 541 and a first connecting member. One end of the first connecting rod 541 is connected to the first rotating shaft 511, and the first connecting rod 541 and the first rotating shaft 511 form an eccentric structure, that is, the first connecting rod 541 and the first rotating shaft 511 are non-concentrically arranged. Specifically, one end of the first connecting rod 541 is hinged to the first connecting portion 5111 of the first rotating shaft 511. A first connecting structure is constructed on one side of the lifting plate 53. The first connecting structure includes two first connecting seats arranged at intervals, and a first through hole is provided on the first connecting seat. The other end of the first connecting rod 541 is provided with a first shaft hole, and the first connecting member includes a first pin shaft and a cotter pin. The first pin shaft passes through the first shaft hole and the two first through holes, and a cotter pin is inserted into the pin hole of the first pin shaft to realize the hinge connection between the lifting plate 53 and the first connecting rod 541.

[0106] The second movable connecting member includes a second connecting rod 542 and a second connecting member, one end of the second connecting rod 542 is connected to the second rotating shaft 512, and the second connecting rod 542 and the second rotating shaft 512 form an eccentric structure, that is, the second connecting rod 542 and the second rotating shaft 512 are non-concentrically arranged. Specifically, one end of the second connecting rod 542 is hinged to the second connecting portion 5121 of the second rotating shaft 512. The other side of the lifting plate 53 is constructed with a second connecting structure, the second connecting structure includes two second connecting seats arranged at intervals, the second connecting seats are provided with a second through hole, the other end of the second connecting rod 542 is provided with a second shaft hole, and the second connecting member includes a second pin shaft and a cotter pin. The second pin shaft passes through the second shaft hole and the two second through holes, and the cotter pin is inserted into the pin hole of the second pin shaft to realize the hinge connection of the lifting plate 53 and the second rotating shaft 512.

[0107] Optionally, one side of the lifting plate 53 is connected to the first rotating shaft 511 through two first movable connecting members, and the other side of the lifting plate 53 is connected to the second rotating shaft 512 through two second movable connecting members, so as to ensure the smooth movement of the lifting plate 53.

[0108] The lifting plate 53 has a top surface facing away from the mounting seat 33 and a bottom surface facing the mounting seat 33. The first part 411 of the first deformation area 41 of the circuit board 40 forms a surface contact with the top surface of the lifting plate 53, the second part 412 forms a rolling contact with the first guide wheel 521, and the third part 413 forms a rolling contact with the second guide wheel 522.

[0109] like Figures 8 to 11As shown, during the switching process of the electronic device from the folded state to the flattened state, the first rotating shaft 511 rotates synchronously with the first rotating shaft 3121, and the second rotating shaft 512 rotates synchronously with the second rotating shaft 3221. The first connecting rod 541 and the second connecting rod 542 move from the first position to the second position along with the rotation of the first rotating shaft 511 and the second rotating shaft 512, driving the lifting plate 53 to move linearly in a direction perpendicular to the mounting seat 33, and the lifting plate 53 rises from the first position to the second position, guiding the first part 411 of the first deformation area 41 of the circuit board 40 to move toward the fourth part 611 close to the screen 60. The first part 411 always remains straight.

[0110] The second part 412 is in rolling contact with the first guide wheel 521. During the process of the lifting plate 53 rising, a top force is applied to the first part 411, driving the first part 411 to move toward the fourth part 611 close to the screen 60. The second part 412 is pulled by the first part 411 and moves along with the movement of the first part 411. The second part 412 moves along the circumferential surface of the first guide wheel 521. It can be understood that the first guide wheel 521 and the first rotating shaft 511 are in clearance fit, and the rotation of the first guide wheel 521 and the first rotating shaft 511 are not synchronized. The rotation speed of the first guide wheel 521 is restricted by the movement speed of the second part 412. The movement of the second part 412 drives the first guide wheel 521 to rotate. The first guide wheel 521 provides an arc-shaped trajectory path for the movement of the second part 412 to control the shape of the second part 412.

[0111] The third part 413 is in rolling contact with the second guide wheel 522. During the process of the lifting plate 53 rising, a top force is applied to the circuit board 40, and the third part 413 moves along with the movement of the first part 411. The third part 413 moves along the circumferential surface of the second guide wheel 522. It can be understood that the second guide wheel 522 and the second rotating shaft 512 are in clearance fit, and the rotation of the second guide wheel 522 and the second rotating shaft 512 is not synchronous. The rotation speed of the second guide wheel 522 is restricted by the movement speed of the third part 413. The movement of the third part 413 drives the second guide wheel 522 to rotate, and the second guide wheel 522 provides an arc-shaped trajectory path for the movement of the third part 413 to control the shape of the third part 413.

[0112] Thus, the electronic device is in a flattened state, the shape of the first portion 411 is controlled by the lifting plate 53, and the first portion 411 is straight, the shape of the second portion 412 is controlled by the first guide wheel 521, and the second portion 412 is a combination of an arc and a straight shape, and the shape of the third portion 413 is controlled by the second guide wheel 522, and the third portion 413 is a combination of an arc and a straight shape. The first deformation region 41 forms a first shape under the control of the lifting plate 53, the first guide wheel 521, and the second guide wheel 522, and the first deformation region 41 is constrained by the lifting plate 53, the first guide wheel 521, and the second guide wheel 522, and can be stably maintained in the first shape.

[0113] When the electronic device switches from the flat state to the folded state, the first rotating shaft 511 and the second rotating shaft 512 rotate synchronously with the first rotating shaft 3121 and the second rotating shaft 3221. The first connecting rod 541 and the second connecting rod 542 move from the second position to the first position as the first rotating shaft 511 and the second rotating shaft 512 rotate, driving the lifting plate 53 to move linearly in a direction perpendicular to the mounting seat 33, and the lifting plate 53 sinks from the second position to the first position.

[0114] During the rotation of the first body 10, a pulling force is applied to the circuit board 40. During the movement of the circuit board 40 toward the end of the first body 10, the second portion 412 moves along the circumferential surface of the first guide wheel 521. The movement of the second portion 412 drives the first guide wheel 521 to rotate. The first guide wheel 521 provides an arcuate trajectory path for the movement of the second portion 412 to control the shape of the second portion 412. During the rotation of the second body 20, a pulling force is applied to the circuit board 40. During the movement of the circuit board 40 toward the end of the second body 20, the third portion 413 moves along the circumferential surface of the second guide wheel 522. The movement of the third portion 413 drives the second guide wheel 522 to rotate. The second guide wheel 522 provides an arcuate trajectory path for the movement of the third portion 413 to control the shape of the third portion 413.

[0115] The first portion 411 of the first deformation region 41 moves toward the fourth portion 611 away from the screen 60 along with the movement of the second portion 412 and the third portion 413 . Restricted by the lifting plate 53 , the first portion 411 always remains straight.

[0116] Thus, the electronic device is in a folded state, the shape of the first part 411 is controlled by the lifting plate 53, and the shape of the first part 411 is straight, the shape of the second part 412 is controlled by the first guide wheel 521, and the shape of the second part 412 is arc-shaped, and the shape of the third part 413 is controlled by the second guide wheel 522, and the shape of the third part 413 is arc-shaped. The first deformation area 41 forms the second shape under the control of the lifting plate 53, the first guide wheel 521 and the second guide wheel 522, and the first deformation area 41 is constrained by the lifting plate 53, the first guide wheel 521 and the second guide wheel 522, and can be stably maintained in the second shape.

[0117] In this embodiment, when the electronic device switches between two postures, the shape of the first deformation area 41 of the circuit board 40 is controlled by the lifting plate 53, the first guide wheel 521 and the second guide wheel 522, so that the first deformation area 41 can stably maintain the first shape or the second shape.

[0118] In the embodiments of the present disclosure, Figure 5 , Figure 8 , Fig. 9 and Fig.10 As shown, the adjustment mechanism 50 further includes a guide rod 55 ; the lifting plate 53 is provided with a guide hole, the guide rod 55 passes through the guide hole, and the lifting plate 53 moves along the axial direction of the guide rod 55 .

[0119] Specifically, the guide rod 55 can be a columnar body, and the guide rod 55 is vertically arranged on the mounting seat 33. A guide hole is provided on the lifting plate 53, and the guide hole is coaxially arranged with the guide rod 55, and the guide rod 55 passes through the guide hole. The guide rod 55 can be arranged at the end area of ​​the lifting plate 53, and can also be arranged at the middle area of ​​the lifting plate 53.

[0120] The lifting plate 53 rises from the first position to the second position with the movement of the first connecting rod 541 and the second connecting rod 542, and moves along the axis direction of the guide rod 55 toward the fourth portion 611 close to the screen 60, ensuring the stability of the rising movement. The lifting plate 53 sinks from the second position to the first position with the movement of the first connecting rod 541 and the second connecting rod 542, and moves along the axis direction of the guide rod 55 toward the fourth portion 611 away from the shield, ensuring the stability of the sinking movement.

[0121] In the embodiments of the present disclosure, Figure 2 , Figure 4 and Fig.11As shown, the electronic device is in a flattened state, and there is a first distance between the top surface of the lifting plate 53 and the second deformation area 61; the electronic device is in a folded state, and there is a second distance between the top surface of the lifting plate 53 and the bottom surface of the guide assembly 52, and the second distance is adapted to the thickness of the circuit board 40 so that the circuit board 40 is clamped between the lifting plate 53 and the guide assembly 52, the first guide member controls the curvature of the second part 412, and the second guide member controls the curvature of the third part 413.

[0122] Specifically, the lifting plate 53 has a top surface facing the screen 60 and a bottom surface facing away from the screen 60. When the electronic device is in a flattened state, the lifting plate 53 rises to the second position, and a first distance is provided between the top surface of the lifting plate 53 and the screen 60. The first distance is slightly larger than the thickness of the circuit board 40 so as to accommodate the circuit board 40. In addition, the lifting plate 53 is prevented from rising to conflict with the screen 60, and the screen 60 is prevented from arching, thereby ensuring the flatness of the screen 60.

[0123] The electronic device is in a folded state, and there is a second spacing between the top surface of the lifting plate 53 and the bottom contour surfaces of the two guide wheels, and the second spacing is adapted to the thickness of the circuit board 40, so that the first part 411 of the circuit board 40 is clamped between the lifting plate 53 and the two guide wheels. The second part 412 contacts the circumferential surface of the first guide wheel 521, and the first guide wheel 521 is used to control the curvature of the second part 412, and the third part 413 contacts the circumferential surface of the second guide wheel 522, and the second guide wheel 522 is used to control the curvature of the second part 412.

[0124] The second deformation area 61 of the screen 60 is in a teardrop shape, and the first deformation area 41 is constrained by the lifting plate 53, the first guide wheel 521 and the second guide wheel 522 to remain in a tapered U-shape, so that the second shape of the first deformation area 41 is adapted to the fourth shape of the second deformation area 61. In addition, it is effectively prevented that the distance between the lifting plate 53 and the two guide wheels is too large, and the phenomenon that the second shape of the first deformation area 41 is uncontrolled is avoided.

[0125] In the embodiments of the present disclosure, Figure 2 and Figure 4As shown, the rotating connection structure 30 further includes a mounting seat 33, and the first rotating assembly 31 and the second rotating assembly 32 are disposed on the mounting seat 33. The adjusting mechanism 50 further includes a supporting panel 56, and the supporting panel 56 is disposed on the mounting seat 33. The second deformation region 61 includes a fourth portion 611 and a fifth portion 612 and a sixth portion 613 located on both sides of the fourth portion 611, and the supporting panel 56 is used to support the fourth portion 611. The supporting panel 56 is spaced apart from the lifting plate 53, and the electronic device is in a flattened state. There is a third spacing between the supporting panel 56 and the lifting plate 53, and the third spacing is adapted to the thickness of the circuit board 40, so that the circuit board 40 is clamped between the supporting panel 56 and the lifting plate 53.

[0126] Specifically, the support panel 56 is mounted on the mounting base 33, and the position of the support panel 56 is relatively fixed. When the electronic device is in a flattened state, the second deformation area 61 of the screen 60 is flat, and the support panel 56 fits the fourth portion 611 of the second deformation area 61, playing a role of effectively supporting the fourth portion 611, thereby ensuring the flatness of the screen 60.

[0127] The electronic device is in a flattened state, the lifting plate 53 rises to the second position, and there is a third distance between the top surface of the lifting plate 53 and the supporting panel 56, which is adapted to the thickness of the circuit board 40, and the first part 411 of the circuit board 40 is clamped between the lifting plate 53 and the supporting panel 56. The first surface of the circuit board 40 contacts the top surface of the lifting plate 53, and the second surface of the circuit board 40 contacts the supporting panel 56. The supporting panel 56 not only supports the screen 60, but also limits the first part 411, so that the first part 411 is stably maintained in a straight state, and further controls the shape of the first part 411.

[0128] In the embodiments of the present disclosure, Figure 2 and Figure 4 As shown, the rotating connection structure 30 also includes a first movable support plate 34 and a second movable support plate 35, the first movable support plate 34 and the second movable support plate 35 are located on opposite sides of the support panel 56, the first movable support plate 34 is connected to the two first rotation track components 311, and the second movable support plate 35 is connected to the two second rotation track components 321. When the electronic device is in a flattened state, the first movable support plate 34, the support panel 56 and the second movable support plate 35 are coplanar to support the fourth part 611, the fifth part 612 and the sixth part 613. When the electronic device is in a folded state, the first movable support plate 34 and the second movable support plate 35 are at a preset angle to accommodate the second deformation area 61 in a bent state.

[0129] Specifically, the rotating connection structure 30 further includes a first movable support plate 34 and a second movable support plate 35, and the first movable support plate 34 and the second movable support plate 35 move toward or away from each other as the first rotating assembly 31 and the second rotating assembly 32 rotate.
