Description

Technical Field

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

[0002] In an inward-folding flexible screen electronic terminal, the two side shells are connected by hinges, allowing them to be flattened and folded. Flexible screen support plates are installed on the inner sides of the two side shells, and the flexible screen is laid on the inner side of the inward-folding flexible screen electronic terminal. In one structure, a left-side movable support plate and a right-side movable support plate supporting the flexible screen are also connected to the hinges. When the inward-folding flexible screen electronic terminal is folded, the left-side and right-side movable support plates rotate at a larger angle (more than 90°) compared to the left and right side shells, thus creating space for the folded bulge in the middle of the flexible screen at the bottom. One approach involves setting up a central support structure for the flexible screen within the inner shell of the inward-folding flexible screen electronic terminal. However, this central support structure requires a clearance groove to accommodate the lower part of the flexible screen when folded (i.e., the bottom in the folded state). If a fully planar support for the flexible screen is required (with the clearance groove on the central support plane being as shallow as possible or even nonexistent), the flexible screen needs sufficient upward movement during folding to avoid interference with the central support plane. This necessitates sufficient upward movement from the side shells to elevate the flexible screen above the central support plane. An overlap area is required between the left and right side shells and the central shell to conceal the internal structure of the electronic terminal. The required upward movement of the left and right side shells in the folded state under fully planar support would cause their lower ends to extend beyond the top of the central shell, exposing the internal structure. Lengthening the left and right shells at the lower ends would cause interference between them when unfolded. Furthermore, the thickness of the rotating connecting arm needs to be reduced to increase the height of the central shell, but this negatively impacts the structural robustness. Utility Model Content

[0003] The purpose of this invention is to provide a hinge for an inward-folding flexible screen electronic terminal, which can conceal the gaps that appear after the left and right shells extend beyond the top of the middle shell while ensuring the upward movement of the left and right shells. To this end, this invention adopts the following technical solution: A hinge for an inward-folding flexible screen electronic terminal includes a central fixed base, a left-side rotating mechanism, and a right-side rotating mechanism. The left-side and right-side rotating mechanisms are respectively provided with a rotating connecting arm and a movable mounting frame rotatably connected to the central fixed base. The movable mounting frame and the rotating connecting arm are slidably connected, with their sliding direction perpendicular to the rotation axis of the rotating connecting arm. The movable mounting frame is provided to connect to the left or right shell of the inward-folding flexible screen electronic terminal. The left-side and right-side rotating mechanisms also include a shielding plate. The shielding plate is located outside the rotating mechanism and can rotate synchronously and in the same direction as the rotating connecting arm based on its rotation axis. The shielding plate includes a shielding plate body. When the inward-folding flexible screen electronic terminal is in a folded state, with its middle shell horizontally placed as a placement reference state, the lower part of the shielding plate body is used to shield the gap between the lower end of the left or right shell of the inward-folding flexible screen electronic terminal and the top of the middle shell.

[0004] Furthermore, the shielding plate is fixed to the rotating connecting arm.

[0005] Furthermore, the shielding plate includes a connecting portion and the shielding plate body, the shielding plate body extends along the rotation axis direction, and the connecting position is partially provided in the length direction of the shielding plate body, the connecting portion being located above the top end of the shielding plate body relative to the lower end.

[0006] To achieve the above objectives, the present invention may also adopt the following technical solutions: A hinge for an inward-folding flexible screen electronic terminal includes a central fixed base, a left-side rotating mechanism, and a right-side rotating mechanism. The left-side and right-side rotating mechanisms are respectively provided with a rotating connecting arm and a movable mounting bracket rotatably connected to the central fixed base. The movable mounting bracket and the rotating connecting arm are slidably connected, with their sliding direction perpendicular to the rotation axis of the rotating connecting arm. The movable mounting bracket is positioned to connect to the left or right side housing of the inward-folding flexible screen electronic terminal. The rotating mechanism also includes a push-pull linkage, one end of which is rotatably connected to the central fixed base, and the other end... One end is rotatably connected to the movable mounting bracket; the rotating mechanism on the left and the rotating mechanism on the right are also provided with a shielding plate, the shielding plate including a shielding plate body, the shielding plate being movably mounted on the hinge and located outside the hinge, the shielding plate is also configured with a motion trajectory control structure, and the displacement trajectory of the shielding plate is controlled so that when the inward folding flexible screen electronic terminal is in the folded state, its middle shell is placed horizontally as the placement reference state, the lower part of the shielding plate body is used to shield the gap between the lower end of the left or right shell of the inward folding flexible screen electronic terminal and the top of the middle shell.

[0007] Furthermore, the movable mounting structure of the shielding plate and the motion trajectory control mechanism include: the shielding plate is movably connected to both the push-pull rod and the movable mounting frame, wherein the shielding plate and the movable mounting frame are slidably connected via a linear slide rail, and the movable connection with the push-pull rod causes the shielding plate to slide along the linear slide rail. The motion trajectory control of the shielding plate is as follows: when the inward-folding flexible screen electronic terminal is folded, the lower part of the shielding plate body is displaced to cover the gap between the lower end of the left or right shell of the inward-folding flexible screen electronic terminal and the top of the middle shell; when the inward-folding flexible screen electronic terminal is flattened, the lower part of the shielding plate body is displaced to the space between the bottom surface of the middle shell and the portion of the left or right shell located below the middle shell.

[0008] Furthermore, the shielding plate is provided with a sliding connecting plate, and the shielding plate is movably connected to the push-pull rod through the sliding connecting plate; the shielding plate body extends along the rotation axis direction, and a connecting part is provided in a local part along the length direction of the shielding plate body, and the connecting part is connected to the sliding connecting plate; relative to the lower end, the connecting part is located above the top end of the shielding plate body.

[0009] Furthermore, the movable connection structure between the shielding plate and the push-pull rod includes a control groove and a pin, which are respectively disposed on the shielding plate and the push-pull rod.

[0010] Furthermore, the sliding path of the movable mounting bracket is inclined to the flexible screen support surface of the left or right shell on the same side; the track of the movable mounting bracket for guiding the sliding of the shielding plate is parallel to the flexible screen support surface.

[0011] According to a second aspect of this utility model, this utility model provides an inwardly folding flexible screen electronic terminal, which, while ensuring the upward movement of the left and right shells, can also conceal the gaps that appear after the left and right shells extend beyond the top of the middle shell. To this end, this utility model adopts the following technical solution: A flexible inward-folding electronic terminal includes a left shell, a right shell, and a middle shell. The flexible inward-folding electronic terminal also features the aforementioned hinge. A central support is connected to the middle shell. When the flexible inward-folding electronic terminal is in a folded state, with the middle shell horizontally positioned as a reference, there are gaps in the left and right directions between the lower inner sides of the left and right shells and the middle shell. The lower part of a shielding plate extends downward from these gaps, shielding the gap between the lower end of the left or right shell and the top of the middle shell. When the flexible inward-folding electronic terminal is in a flattened state, the lower part of the shielding plate is located between the bottom surface of the middle shell and the portion of the left or right shell located below the middle shell.

[0012] Based on the above technical solution, the present invention may also adopt the following further technical solutions, or combine these further technical solutions: By employing the technical solution of this utility model, the shielding plate allows the inward-folding flexible screen electronic terminal to be shielded even when there is no overlap between the left and right side shells and the middle shell in the folded state. This ensures both the appearance of the inward-folding flexible screen electronic terminal when folded and eliminates the need for a clearance groove on the central support surface. When the inward-folding flexible screen mobile terminal is unfolded, the central part of the flexible screen is fully supported without sacrificing the thickness of the rotating connecting arm. Furthermore, this utility model can be applied to hinges of different structures. Attached Figure Description

[0025] Referring to the attached drawings, the hinge of the inward-folding flexible screen electronic terminal includes a left shell 101, a right shell 102, and a middle shell 200. The hinge of the inward-folding flexible screen electronic terminal also includes the hinge of this utility model. Figure 1 , 5 Only a portion of the left housing 101 and the right housing 102 located at the bottom is shown in the image.

[0026] The inward-folding flexible screen electronic terminal hinge provided by this utility model includes a central fixed base 201, a rotating mechanism located on the left side and a rotating mechanism located on the right side. The central fixed base 201 is disposed in the intermediate housing 200 and is fixedly connected to the intermediate housing 200.

[0027] The left-side and right-side rotating mechanisms are respectively equipped with a rotating connecting arm 1 and a movable mounting bracket 2 rotatably connected to the central fixed base 201. The movable mounting bracket 2 and the rotating connecting arm 1 are slidably connected, with their sliding direction perpendicular to the rotation axis 10 of the rotating connecting arm 1. Reference numeral 11 indicates the slidable connection structure between the rotating connecting arm 1 and the movable mounting bracket 2. The movable mounting bracket 2 is provided with a portion connecting to the left-side housing 101 or the right-side housing 102 of the inward-folding flexible screen electronic terminal, such as a screw connection portion. The left-side housing 101 and the right-side housing 102 are respectively fixedly connected to the movable mounting bracket 2 of the left-side and right-side rotating mechanisms. A synchronous reverse rotation connecting mechanism, such as a gear connecting mechanism, is connected between the rotating connecting arms 1 of the left-side and right-side rotating mechanisms, enabling the left-side and right-side rotating mechanisms to rotate synchronously in opposite directions.

[0028] The left-side and right-side rotating mechanisms are also equipped with shielding plates. The shielding plates are located outside the rotating mechanisms and can rotate synchronously and in the same direction as the rotating connecting arm 1 based on the rotation axis of the rotating connecting arm 1. The rotation axis is the center line of the rotating shaft 10. The shielding plate includes a shielding plate body 40. When the inward-folding flexible screen electronic terminal is in the folded state, with the middle shell 200 placed horizontally as the placement reference state, the lower part of the shielding plate body 40 of the left-side and right-side rotating mechanisms is used to shield the gap between the lower end of the left shell 101 and the right shell 102 of the inward-folding flexible screen electronic terminal and the top of the middle shell, respectively. This gap is shown as position D in the figure.

[0029] See Figures 1-4 and Figure 12 In this embodiment, the shielding plate is fixed to the rotating connecting arm 1. This solution is suitable when the sliding direction of the movable mounting bracket 2 is parallel to the flexible screen support surface 100 of the left or right shell on the same side.

[0030] The shielding plate 4 includes a connecting portion 41 and a shielding plate body 40. The shielding plate body 40 extends along the rotation axis, and the connecting portion 41 is partially provided along the length of the shielding plate body 40. Relative to the lower end, the connecting portion 41 is located above the top end of the shielding plate body. This ensures that the shielding plate 4 can accommodate the length of the gap D and reach the gap D even when the width of the shielding plate body 40 is as narrow as possible, while also avoiding interference with other structures in the hinge. The connecting portion 41 is connected to the rotating connecting arm 1 by screws.

[0031] There is also a gap W in the left-right direction between the lower inner side of the left shell 101 and the right shell 102 and the middle shell 200. The lower part of the shielding plate 40 extends downward from the gap W in the left-right direction to shield the gap D between the lower end of the left shell 101 or the right shell 102 and the top of the middle shell 200. When the inward folding flexible screen electronic terminal is in the flattened state, the lower part of the shielding plate 40 used to shield the gap D is located between the bottom surface of the middle shell 200 and the part of the left shell 101 or the right shell located below the middle shell.

[0032] See Figures 5-10 and Figure 12 The left and right rotating mechanisms of the hinge also include a push-pull link 3. One end of the push-pull link 3 is rotatably connected to the central fixed base 201, and the other end is rotatably connected to the movable mounting frame 2. Reference numeral 31 shows the rotating connection structure between the push-pull link 3 and the central fixed base 201, and reference numeral 32 shows the structure between the push-pull link 3 and the movable mounting frame 2. The shielding plate is slidably connected to the sliding mounting frame 2, and its sliding direction is perpendicular to the rotation axis.

[0033] The rotating mechanism on the left and the rotating mechanism on the right are also provided with shielding plates. The shielding plate includes a shielding plate body 40. The shielding plate is movably mounted on the hinge and located outside the hinge. The shielding plate is also configured with a motion trajectory control structure to control the displacement trajectory of the shielding plate so that when the inward folding flexible screen electronic terminal is in the folded state, with its middle shell 200 placed horizontally as the placement reference state, the lower part of the shielding plate body 40 shields the gap D between the lower end of the left shell 101 or the right shell 102 of the inward folding flexible screen electronic terminal and the top of the middle shell 200.

[0034] The movable mounting structure of the shielding plate and the motion trajectory control mechanism include: the shielding plate is movably connected to the push-pull rod 3 and the movable mounting frame 2, wherein the shielding plate and the movable mounting frame 2 are slidably connected by a linear slide rail 21, and the movable connection between the shielding plate and the push-pull rod causes the shielding plate to slide along the linear slide rail. The motion trajectory control of the shielding plate is as follows: when the inward-folding flexible screen electronic terminal is folded, the lower part of the shielding plate body 40 is displaced to cover the gap D between the lower end of the left or right shell of the inward-folding flexible screen electronic terminal and the top of the middle shell; when the inward-folding flexible screen electronic terminal is flattened, the lower part of the shielding plate body 40 used to cover the gap D is displaced to the area between the bottom surface of the middle shell 200 and the portion of the left shell 101 or right shell 102 located below the middle shell 200.

[0035] The shielding plate is provided with a sliding connecting plate 42, which is movably connected to the push-pull rod 3. Simultaneously, the sliding connecting plate is also slidably connected to the linear slide rail 21, and the shielding plate is slidably connected to the linear slide rail 21 via its sliding connecting plate 42. The shielding plate body 40 extends along the rotation axis and has a connecting portion 41 partially provided along its length. The connecting portion 41 is connected to the sliding connecting plate 42. Relative to the lower end, the connecting portion 41 is located above the top end of the shielding plate body 40. This not only ensures that the shielding plate can accommodate the length of the gap D and reach the gap D even when the width of the shielding plate body 40 is as narrow as possible, but also avoids interference with other structures in the hinge.

[0036] The movable connection structure between the shielding plate and the push-pull rod 3 includes a control groove 43 and a pin 33, which are respectively disposed on the shielding plate and the push-pull rod.

[0037] This structure in this embodiment is applicable whether the sliding trajectory of the movable mounting bracket 2 is parallel or non-parallel to the flexible screen support surface of the left or right shell on the same side. When they are not parallel, the sliding path of the movable mounting bracket 2 is inclined to the flexible screen support surface 100 of the left or right shell on the same side, the shielding plate 40 is parallel to the flexible screen support surface 100, the sliding trajectory of the sliding connecting plate 42 is parallel to the flexible screen support surface 100, and the sliding track of the sliding connecting plate 42 provided on the movable mounting bracket 2 is parallel to the flexible screen support surface 100.

[0038] There is also a gap W in the left-right direction between the lower inner side of the left shell 101 and the right shell 102 and the middle shell 200. The lower part of the shielding plate 40 extends downward from the gap W in the left-right direction to shield the gap D between the lower end of the left shell 101 or the right shell 102 and the top of the middle shell 200. When the inward folding flexible screen electronic terminal is in the flattened state, the lower part of the shielding plate 40 used to shield the gap D is located between the bottom surface of the middle shell 200 and the part of the left shell 101 or the right shell located below the middle shell.
