[0046] The folding screen electronic device becomes a development trend in the future due to its portability, intelligent use and excellent display effect. The hinge structure performance of the folding screen electronic device directly affects the function and use experience of the whole machine. The floating plate of the hinge mechanism can support the screen body. In the related technology, the floating plate is a one-piece structure, and the wrapping performance of the screen body is poor, and cannot achieve comprehensive support.

[0047] The present disclosure provides a floating plate applied to a screen module. Figure 1 is a front exploded structure schematic diagram of a floating plate in an exemplary embodiment of the present disclosure, Figure 2 is a back exploded structure schematic diagram of a floating plate in an exemplary embodiment of the present disclosure, Figure 3 is an assembled structure schematic diagram of a floating plate in an exemplary embodiment of the present disclosure, and Figures 1-3As shown, the floating plate 1 comprises a first body 11 and a second body 12. The first body 11 comprises a first support surface 111 and a first connecting structure 112, and the second body 12 comprises a second support surface 121 and a second connecting structure 122. The first connecting structure 112 and the second connecting structure 122 are rotationally connected to switch the first body 11 and the second body 12 to a preset relative posture. When the first body 11 and the second body 12 are in the preset relative posture, the first support surface 111 and the second support surface 121 form a screen support structure.

[0048] In the above embodiment, the floating plate 1 comprises the first body 11 and the second body 12 rotationally connected, so that the first body 11 and the second body 12 can switch the relative posture according to the form of the screen body. When the first body 11 and the second body 12 are in the preset relative posture, the first support surface 111 of the first body 11 and the second support surface 121 of the second body 12 form a screen support structure adapted to the screen form, and jointly support the screen body, which helps to improve the wrapping property of the floating plate 1 to the screen body, and further improves the screen use effect and reliability.

[0049] In some embodiments, the first connecting structure 112 comprises a first hinge hole provided on the first body 11, the second connecting structure 122 comprises a second hinge hole provided on the second body 12, and the first hinge hole and the second hinge hole are rotationally connected through the pin shaft 13. The rotationally connecting of the first body 11 and the second body 12 is realized by the pin shaft 13 passing through the first hinge hole and the second hinge hole, which is simple and reliable in structure.

[0050] In other embodiments, one of the first connecting structure 112 and the second connecting structure 122 can be an arc-shaped plate, and the other can be an arc-shaped groove. The rotationally connecting of the first body 11 and the second body 12 can be realized by inserting the arc-shaped plate into the arc-shaped groove. Alternatively, one of the first connecting structure 112 and the second connecting structure 122 can be a rotation hole, and the other can be a rotation shaft. The rotationally connecting of the first body 11 and the second body 12 can be realized by inserting the rotation shaft into the rotation hole. Alternatively, the first connecting structure 112 and the second connecting structure 122 can also be other structures capable of realizing rotationally connecting, and the present disclosure does not limit this.

[0051] Taking the first connecting structure 112 as the first hinge hole and the second connecting structure 122 as the second hinge hole as an example, the first hinge hole and the second hinge hole can be provided in various ways on the first body 11 and the second body 12, which will be described exemplarily as follows:

[0052] In some embodiments, the first body 11 includes a first support portion 115 and a first lug. The first support portion 115 includes a first support surface 111 and a first side surface bent relative to the first support surface 111. The first lug is disposed on the first side surface, and a first hinge hole is disposed on the first lug. The second body 12 includes a second support portion and a second lug. The second support portion includes a second support surface 121 and a second side surface bent relative to the second support surface 121. The second lug is disposed on the second side surface, and a second hinge hole is disposed on the second lug. The first lug is disposed on the first side surface of the first support portion 115, and the second lug is disposed on the second side surface of the second support portion. Therefore, the first hinge hole and the second hinge hole avoid structural interference with the first support portion 115 and the second support portion when rotatably connected by the pin 13, thus improving the reliability of the rotatable connection.

[0053] Among them, such as Figure 4 , Figure 5 As shown, at least one side of the first lug can be provided with a third sector-shaped structure 1121 along the axial direction of the first hinge hole. The third sector-shaped structure 1121 avoids the first hinge hole, and the end faces of the third sector-shaped structure 1121 form an active space for the second body 12. During the relative rotation of the first body 11 and the second body 12, the portion of the second body 12 located in the active space can move within the active space, and the end faces of the third sector-shaped structure 1121 can be used to limit the rotation of the second body 12. The aforementioned third sector-shaped structure 1121 not only limits the rotation range of the second body 12, but also provides auxiliary support for the overall rotation when the second body 12 abuts against the end faces of the third sector-shaped structure 1121, thereby improving the reliability of the limiting mechanism.

[0054] And / or, along the axial direction of the second hinge hole, at least one side of the second lug is provided with a fourth sector-shaped structure. The fourth sector-shaped structure avoids the second hinge hole, and the end faces of the fourth sector-shaped structure form an active space for the first main body 11. During the relative rotation of the first main body 11 and the second main body 12, the portion of the first main body 11 located in the active space can move within the active space, and the end faces of the fourth sector-shaped structure can be used to limit the rotation of the first main body 11. The aforementioned fourth sector-shaped structure not only limits the rotation range of the second main body 12, but also provides auxiliary support for the overall rotation when the first main body 11 abuts against the end faces of the fourth sector-shaped structure, thereby improving the reliability of the limiting mechanism.

[0055] It should be noted that the first lug portion and the second lug portion can each be a single lug structure. Alternatively, one of the first lug portion and the second lug portion can be a pair of lug structures arranged in pairs, and the other can be a single lug structure. The pair of lug structures forms an assembly space for assembling the single lug structure. After the single lug structure is assembled between the pair of lug structures and connected by the pin shaft 13, the rotation connection reliability can be improved.

[0056] In the above embodiment, the first support surface 111 is provided with the first recess 114, and the second support surface 121 is provided with the second recess 124. The first recess 114 and the second recess 124 form a channel that is in communication with each other. Since the first lug portion is located on the first side surface of the first support portion 115, and the second lug portion is located on the second side surface of the second support portion, the first lug portion and the second lug portion do not interfere with the structure of the first support surface 111 and the second support surface 121, and the space requirements of the first recess 114 on the first support surface 111 and the second recess 124 on the second support surface 121 are met. The channel can be used to pass a graphite sheet, an FPC between the floating plate 1 and the screen, or to avoid the structure of the screen or the hinge mechanism.

[0057] In some embodiments, as shown in Figure 6 , Figure 7 The first body 11 further includes a first limiting piece 113, and the preset relative attitude includes a flat state. When the first body 11 and the second body 12 are in the flat state, the first limiting piece 113 is overlapped and limited with the second body 12 to limit the relative position of the first body 11 and the second body 12 in the flat state, thereby avoiding over-expansion.

[0058] And / or, as shown in Figure 8 , Figure 9 The second body 12 further includes a second limiting piece 123, and the preset relative attitude includes a flat state. When the first body 11 and the second body 12 are in the flat state, the second limiting piece 123 is overlapped and limited with the first body 11 to limit the relative position of the first body 11 and the second body 12 in the flat state, thereby avoiding over-expansion.

[0059] That is, the first limiting piece 113 and the second limiting piece 123 can be separately provided to obtain the limiting effect, and the first limiting piece 113 and the second limiting piece 123 can also coexist to obtain the limiting effect.

[0060] It should be noted that the first limiting member 113 described above can be a limiting plate protruding from the first support portion 115, which abuts against one side of the second body 12 when the first body 11 and the second body 12 are in the unfolded state. Alternatively, the first limiting member 113 can also be a fan-shaped structure protruding from the first support portion 115, which, when the first body 11 and the second body 12 are in the unfolded state and in a folded state, abuts against both sides of the second body 12 through two end faces in the rotating direction to limit the rotation of the second body 12. Similarly, the second limiting member 123 described above can be a limiting plate protruding from the second support portion, which abuts against one side of the first body 11 when the second body 12 and the first body 11 are in the unfolded state. Alternatively, the second limiting member 123 can also be a fan-shaped structure protruding from the second support portion, which, when the second body 12 and the first body 11 are in the unfolded state and in a folded state, abuts against both sides of the first body 11 through two end faces in the rotating direction to limit the rotation of the first body 11.

[0061] In the above embodiment, the first body 11 can include a pair of first connecting structures 112. In the rotating axial direction, the first body 11 includes a first end portion and a second end portion, and at least one pair of first connecting structures 112 is arranged at the first end portion and the second end portion, respectively. The first limiting member 113 is located in the middle section between the first end portion and the second end portion. The second body 12 includes a pair of second connecting structures 122. In the rotating axial direction, the second body 12 includes a third end portion and a fourth end portion, and at least one pair of second connecting structures 122 is arranged at the third end portion and the fourth end portion, respectively. The second limiting member 123 is located in the middle section between the third end portion and the fourth end portion. Through the rotating connection of the first connecting structures 112 and the second connecting structures 122 at both ends and the rotating limitation of the first limiting member 113 and the second limiting member 123 in the middle section, the relative rotation of the first body 11 and the second body 12 is realized, and the effective support of the first body 11 and the second body 12 in the unfolded state can be formed.

[0062] Further, when the first connecting structure 112 includes a third fan-shaped structure 1121 and the second connecting structure 122 includes a fourth fan-shaped structure, the first connecting structure 112 and the second connecting structure 122 can further utilize the effect of rotating connection and auxiliary limiting.

[0063] In the above embodiments, the first body 11 comprises a first support portion 115 and a first limiting member 113, the first limiting member 113 comprises a first fan-shaped structure extending from the edge of the first support portion 115, and the end faces of the fan-shaped structure form a first movable space of the second body 12. And / or, the second body 12 comprises a second support portion and a second limiting member 123, the second limiting member 123 comprises a second fan-shaped structure extending from the edge of the second support portion, and the end faces of the fan-shaped structure form a second movable space of the first body 11. The rotation of the second body 12 is limited by the abutting and limiting of the two end faces of the fan-shaped structure in the rotation direction and the two sides of the second body 12. The rotation of the first body 11 is limited by the abutting and limiting of the two end faces of the fan-shaped structure in the rotation direction and the two sides of the first body 11.

[0064] In some embodiments, the first limiting member 113 and the second limiting member 123 can be staggered in the rotation axis direction to improve the support reliability in the rotation axis direction.

[0065] In some embodiments, the area of the first support surface 111 is greater than the area of the second support surface 121, so that the first support surface 111 matches the size of the screen planar area, the second support surface 121 matches the size of the screen bending area, and the rotation flexibility of the second support surface 121 relative to the second support surface 121 is improved. For example, when the first body 11 and the second body 12 are plate-shaped structures, the first support surface 111 is a side surface of the first body 11, the second support surface 121 is a side surface of the second body 12, the cross-sectional dimension of the first body 11 in the thickness direction is greater than the cross-sectional dimension of the second body 12 in the thickness direction, so that the second body 12 matches the size of the screen bending area, and the movement flexibility of the second body 12 is improved.

[0066] The present disclosure further provides a hinge mechanism, such as Figure 10 As shown, the hinge mechanism comprises the floating plate 1.

[0067] It should be noted that the above-mentioned hinge mechanism can comprise a rotating assembly, a transmission assembly connected with the rotating assembly, and the floating plate 1, and the floating plate 1 can be symmetrically arranged on the rotating assembly or located on one side of the rotating assembly, and the present disclosure does not limit this. In addition, the transmission assembly can form a two-stage linkage or a three-stage linkage or a multi-stage linkage, and the present disclosure does not limit this.

[0068] The present disclosure further provides an electronic device comprising the floating plate 1 or the hinge mechanism.

[0069] The electronic device can further comprise a screen body, the screen body cooperates with the hinge mechanism to form a screen module, and the floating plate 1 of the hinge mechanism can support the screen module in the bending or flattening state of the screen body, so as to improve the use reliability of the screen body.

[0070] Due to the floating plate 1 comprising the rotationally connected first body 11 and second body 12, the first body 11 and second body 12 can switch relative postures with the screen body form. When the first body 11 and second body 12 are in a preset relative posture, the first supporting surface 111 of the first body 11 and the second supporting surface 121 of the second body 12 form a screen supporting structure adapted to the screen form, and jointly support the screen body, which helps to improve the wrapping property of the floating plate 1 to the screen body, and further improves the screen use effect and reliability.

[0071] It should be noted that the electronic device can be a mobile phone, a tablet computer, a vehicle-mounted terminal, a medical terminal, a wearable device, a robot, etc., and the present disclosure is not limited thereto.

[0072] The above only describes the preferred embodiments of the present disclosure, and does not limit the present disclosure in any form. Although the present disclosure has been disclosed as the above preferred embodiments, it is not intended to limit the present disclosure. Any person skilled in the art can make some changes or modifications to the above disclosed technical content without departing from the scope of the technical solution of the present disclosure, and any simple modification, equivalent change and modification of the above embodiments according to the technical essence of the present disclosure are still within the scope of the technical solution of the present disclosure.
