Description

Technical Field

[0001] This utility model relates to a hinge for a flexible screen folding electronic terminal, which can be a mobile phone, laptop computer, etc. Background Technology

[0002] In flexible foldable electronic devices, the increasing demand for thinness inevitably leads to interference between the central flexible screen support plate and hinge components, necessitating the creation of openings in the central support plate. Furthermore, in some structures using two movable support plates to support the central flexible screen, gaps also exist between the two plates. All of these factors negatively impact the user experience of touching the central flexible screen.

[0003] Furthermore, after a period of use, the flexible screen in flexible foldable electronic terminals will generally have residual creases in the middle. When the flexible screen is unfolded, these residual creases have a significant impact on improving the user experience. Utility Model Content

[0004] The purpose of this invention is to provide a hinge for a flexible screen folding electronic terminal, which can tension the flexible screen when the flexible screen folding electronic terminal is in a flattened state, thereby at least partially improving the user experience of touch operation in the middle of the flexible screen and at least alleviating the problem of creases in the middle. To this end, this invention adopts the following technical solution:

[0005] A hinge for a flexible folding electronic terminal includes a central support, a left-side rotating connection structure, and a right-side rotating connection structure. The left-side and right-side rotating connection structures are respectively positioned to connect to the left and right shells of the flexible folding electronic terminal. The central support comprises a fixed support and a left-side movable support and a right-side movable support located to the left and right of the fixed support, respectively. The left-side and right-side movable supports are supported on the fixed support and slidably connected to it, allowing them to slide left and right. The left-side and right-side rotating connection structures are rotatably mounted on the left-side and right-side movable supports, respectively, and can slide left and right together with them. Elastic mechanisms are provided between the fixed support and the left-side movable support, and between the fixed support and the right-side movable support. When the hinge is in a flattened state corresponding to the flexible folding electronic terminal, the elastic mechanisms on the left and right sides respectively push against the left-side and right-side movable supports in a direction away from the fixed support.

[0006] Based on the above technical solution, the present invention may also adopt the following further technical solutions, or combine these further technical solutions:

[0007] The left-side rotating connection structure includes a left-side connecting arm, a left-side sliding frame, and a left-side push-pull linkage. The right-side rotating connection structure includes a right-side connecting arm, a right-side sliding frame, and a right-side push-pull linkage. The left-side and right-side sliding frames are slidably connected to the left-side and right-side connecting arms, respectively. The left-side and right-side sliding frames can slide along rotation axes perpendicular to the left-side and right-side connecting arms, respectively, when the flexible screen foldable electronic terminal is opened and folded. The left-side and right-side sliding frames are respectively provided with connection points to the left-side and right-side housings of the flexible screen foldable electronic terminal. The left-side and right-side connecting arms are rotatably mounted on the left-side and right-side movable supports, respectively. The first ends of the left-side and right-side push-pull linkages are rotatably mounted on the left-side and right-side movable supports, respectively. The left-side and right-side sliding frames are rotatably connected to the second ends of the left-side and right-side push-pull linkages, respectively.

[0008] The fixed support is respectively provided with the guide rail and limiting structure of the left movable support and the guide rail and limiting structure of the right movable support.

[0009] The limiting structure includes a rear support and limiting structure, a lower support and limiting structure, and a front limiting structure.

[0010] The elastic mechanism employs an elastic element, or is a mechanism consisting of an elastic element and a mechanical connection structure. The range of elastic elements includes wire springs, sheet springs, disc springs, and rubber blocks. The wire spring is configured as a compression spring or a torsion spring.

[0011] The first end of the push-pull linkage and the movable support are connected by a virtual circular center rotation connection structure of a circular arc slider and a circular arc guide groove.

[0012] The left-side rotating connection structure and the right-side rotating connection structure are connected by a synchronous reverse rotating connection structure.

[0013] The left and right connecting arms are connected by a synchronous reverse rotation connection structure.

[0014] During the rotation of the flexible screen foldable electronic terminal from folding to unfolding, the left sliding frame and the right sliding frame slide towards the rotation axis of the left connecting arm and the rotation axis of the right connecting arm, respectively. During the rotation of the flexible screen foldable electronic terminal from unfolding to folding, the left sliding frame and the right sliding frame slide away from the rotation axis of the left connecting arm and the rotation axis of the right connecting arm, respectively.

[0015] The left sliding frame and the left connecting arm are movably connected to the left movable support plate in the middle of the flexible screen, and the right sliding frame and the right connecting arm are movably connected to the right movable support plate in the middle of the flexible screen.

[0016] By adopting the technical solution of this utility model, this utility model can stretch the flexible screen outward when it is unfolded, so that it has a certain prestress, which can provide better reaction force for touch operation and make it less likely for the operator to feel the unsupported part on the back of the flexible screen, thereby improving the touch operation experience and also helping to eliminate residual creases in the middle of the flexible screen; moreover, this outward stretching movement does not interfere with the folding and unfolding movement of the flexible screen folding electronic terminal.

[0024] Referring to the accompanying drawings, the flexible screen folding electronic terminal includes a left shell 201, a right shell 202, a flexible screen 300, and the hinge of this invention. The left shell 201 and right shell 202 each contain a flexible screen support plate. The flexible screen 300 is disposed inside the flexible screen folding electronic terminal and is connected to the left shell 201 and right shell 202 respectively. The left shell 201, right shell 202, and the hinge of this invention are connected to each other, allowing the flexible screen to be folded and flattened. The hinge provided by this invention includes a central support, a left-side rotating connection structure, and a right-side rotating connection structure. The left-side and right-side rotating connection structures are respectively provided with connection points to the left shell 201 and right shell 202 of the flexible screen folding electronic terminal. The central support includes a fixed support 203 and a left movable support 2031 and a right movable support 2032 located on the left and right sides of the fixed support, respectively. The left movable support 2031 and the right movable support 2032 are respectively supported on the fixed support 203 and are slidably connected to the fixed support 203, allowing them to slide to the left and right. The left rotating connection structure and the right rotating connection structure are rotatably mounted on the left movable support 2031 and the right movable support 2032, respectively, and can slide to the left and right together with the left movable support 2031 and the right movable support 2032, respectively. Elastic mechanisms are provided between the movable supports 2031 and between the fixed support 203 and the right movable support 2032. When the hinge is in the flattened state corresponding to the flexible screen folding electronic terminal, the elastic mechanisms on the left and right sides press the left movable support 2031 and the right movable support 2032 away from the fixed support 203, respectively. This causes the left rotating connection structure and the left shell 201 connected to the left rotating connection structure, as well as the right rotating connection structure and the right shell 202 connected to the right connection structure, to be acted accordingly. When the flexible screen folding electronic terminal is in the flattened state, the flexible screen is tensioned.

[0025] The fixed support 203 is fixed in the middle shell 400 of the flexible screen folding electronic terminal.

[0026] The fixed support 203 may be provided with a accommodating space 204 for a mechanism that can accommodate an elastic top sliding frame, which may be provided on the left and right sides of the fixed support 203, or on the left movable support 2031 and the right push-pull connecting rod 42.

[0027] The fixed support 203 is respectively provided with the guide rail 2051 and the limiting structure of the left movable support 2031 and the guide rail 2052 and the limiting structure of the right movable support 2032. The limiting structure includes a rear support and limiting structure 2061, a lower support and limiting structure 2062 and a front limiting structure 2063.

[0028] In this embodiment, the elastic mechanism uses an elastic element 3.

[0029] In this embodiment, the left rotating connection structure includes a left connecting arm 11, a left sliding frame 21, and a left push-pull link 41, and the right rotating connection structure includes a right connecting arm 12, a right sliding frame 22, and a right push-pull link 42. The left sliding frame 41 and the right sliding frame 42 are slidably connected to the left connecting arm 11 and the right connecting arm 12, respectively. The left sliding frame 41 and the right sliding frame 42 can slide along the rotation axis perpendicular to the left connecting arm 11 and the rotation axis perpendicular to the right connecting arm 12, respectively, when the flexible screen folding electronic terminal is opened and folded. The left sliding frame 21 and the right sliding frame 22 are respectively provided with slide rails 211 and 221 that cooperate with the left connecting arm 11 and the right connecting arm 12.

[0030] The left sliding bracket 21 and the right sliding bracket 22 are respectively provided with connection points to the left and right shells of the flexible screen folding electronic terminal, such as screw connection points 210 and 220, and are connected to the left shell 201 and the right shell 202. The left connecting arm 11 and the right connecting arm 12 are rotatably mounted on the left movable support 2031 and the right movable support 2032, respectively. Reference numerals 110 and 120 are the axes of the left connecting arm 11 and the right connecting arm 12, respectively. The left sliding bracket 21 and the right sliding bracket 22 are rotatably connected to the second ends of the left push-pull linkage 41 and the right push-pull linkage 42, respectively, and can adopt a rotatable connection structure with a hole and shaft 45.

[0031] The first ends of the left push-pull link 41 and the right push-pull link 42 are rotatably mounted on the left movable support 2031 and the right movable support 2032, respectively, and are connected by a virtual center rotation connection structure 40 composed of an arc slider and an arc guide groove. The rotation center is located above the height of the support surface of the flexible screen when the flexible screen folding electronic terminal is unfolded. Reference numerals 2033 and 2034 are cover plates fixed on the left movable support 2031 and the right movable support 2032, and can also be used to limit the first ends of the left push-pull link 41 and the right push-pull link 42. The cover plates 2033 and 2034 can be connected to the left movable support 2031 and the right movable support 2032 by screws, respectively.

[0032] The left connecting arm 11 and the right connecting arm 12 are connected by a synchronous reverse rotation connection structure 10, which can be a gear meshing connection structure, so that the housings 201 and 202 on both sides rotate synchronously in opposite directions.

[0033] The left sliding frame 21 and the left connecting arm 11 are movably connected to the left movable support plate 51 in the middle of the flexible screen, and the right sliding frame 22 and the right connecting arm 12 are movably connected to the right movable support plate 52 in the middle of the flexible screen. When the flexible screen folding electronic terminal is unfolded, the left movable support plate 51 and the right movable support plate 52 in the middle of the flexible screen rotate to the position supporting the flexible screen 300, as shown below. Figure 8 As shown, when the flexible screen folding electronic terminal is folded, it rotates at a greater angle than the left shell 201 and the right shell 202, thus creating a clearance space for the central bulge portion 301 when the flexible screen is folded.
