For mobile terminals with external flexible screens, which are set on the outside of the mobile terminal, it is necessary to deal with the length change caused by the closing and opening of the hinge. For the middle part of the hinge, some hinges use a structure of multiple supports to achieve support and shape changes when bending and flattening.

[0003] 1) However, the existing hinge structure is generally complex and has a high manufacturing cost. In addition, the hinge with a complex structure is prone to component damage or irreversible damage to the flexible screen during long-term use, which affects the service life of the foldable electronic device.

[0004] 2) The existing hinge structure for flexible screens generally has poor linkage feedback of its internal structure when the hinge rotates, the smoothness of the hinge rotation cannot be guaranteed, and the transmission hinge structure for flexible screens does not have an angle limiting function.

[0005] 3) The traditional hinge structure for flexible screens cannot be well closed between each joint when closed, which makes the hinge larger and also forces electronic devices using traditional hinge structures to be unable to be thin and light, affecting the overall appearance of the device and the sales of the device.

[0013] As a preferred technical solution of the present invention, the first synchronous rotation mechanism includes a first fixed boss B and a first fixed boss A respectively installed on the second shrimp shell member and the third shrimp shell member, and a rotating center axis is smoothly connected in the grooves at the top of the first fixed boss B and the first fixed boss A.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: the outer flexible screen mobile phone structure of the present invention has the following beneficial effects:

[0018] 1) By providing multiple shrimp shells, the total length of each shrimp shell attached to the flexible screen remains unchanged after unfolding and closing, thereby reducing the tension and pressure on the flexible screen during movement. At the same time, the unfolded shrimp shells can smoothly support the flexible screen, thereby preventing the flexible screen from being damaged by the strong stress generated by the rotation of the hinge;

[0019] 2) Through the multiple shrimp shell parts provided, and the multiple shrimp shell parts are hinged through the synchronous rotation mechanism, the rotation mechanism and the rotation limit mechanism, the multiple shrimp shell parts can reliably rotate in a linked manner around their respective centers, and the multiple shrimp shell parts inside the hinge can reliably rotate in a linked manner around their respective centers, while also ensuring the smoothness of the hinge rotation. The two meshing wings of the rotation limit mechanism can play a certain limiting role when the hinge rotates. At the same time, the multiple crescent modules provided can limit the upper shell module and the lower shell module to 180° rotation to avoid damage to the flexible screen;

[0020] 3) The synchronous rotation mechanism inside the hinge part is connected by a multi-link structure of a spatial linkage. When the hinge rotates, the distance between the structures connected by the connecting parts is directly shortened, and the angle is adjusted automatically to absorb this part of the distance, so that the structural parts connected to the synchronous rotation mechanism are not subject to extrusion or tension. At the same time, when the synchronous rotation mechanism structure is closed, the required Z-direction space is small, which saves the internal space of the hinge part and meets the trend of thin and light design of mobile phones. At the same time, the elastic buffer mechanism can slide and guide the toothed wing of the limit rotation mechanism when it is folded and unfolded, and play a certain elastic buffering role on the toothed wing. At the same time, the spring is used to elastically tighten the two screen modules at 0 degrees and 180 degrees to ensure that the screen module has a good stable state when it is fully opened or closed.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1-4 The present invention provides a mobile phone structure with an outer flexible screen, including a hinge 1, the hinge 1 is used to rotatably connect a first screen module 2 and a second screen module 3 and realize the installation of a flexible display screen on the outer sides of the two screen modules, the hinge 1 includes five parallel and synchronously rotatable first shrimp shell members 11, second shrimp shell members 12, third shrimp shell members 13, fourth shrimp shell members 14 and fifth shrimp shell members 15, and two crescent modules 1b and two first synchronous rotation mechanisms 1c symmetrically arranged in the middle of the hinge 1 for connecting the five shrimp shell members to realize rotation, and the sides of the shrimp shell members facing each other are fixed with closing members 1f, when the hinge 1 is closed, the two closing members 1f facing each other fit each other, and can also play a certain guiding role in the movement of the shrimp shell members and shield and protect the components inside the shrimp shell members;

[0028] The second shrimp shell member 12 and the third shrimp shell member 13 are symmetrically arranged on both sides of the first shrimp shell member 11. The first shrimp shell member 11 realizes the synchronous rotation of the second shrimp shell member 12 and the third shrimp shell member 13 through the installed crescent module 1b. The connecting parts of the first synchronous rotation mechanism 1c are respectively installed on the second shrimp shell member 12, the third shrimp shell member 13, the fourth shrimp shell member 14 and the fifth shrimp shell member 15 and cooperate with the crescent module 1b installed on the first shrimp shell member 11 to realize the synchronous rotation of the five shrimp shell members;

[0029] The hinge 1 also includes a limit rotation mechanism 1a symmetrically arranged and installed near the end of the first shrimp shell member 11, a second synchronous rotation mechanism 1d symmetrically arranged and installed in the middle of the first shrimp shell member 11, and two synchronous sliding mechanisms 1e symmetrically arranged and respectively located on both sides of the first shrimp shell member 11. The limit rotation mechanism 1a is rotationally connected with two elastic buffer mechanisms 4 respectively installed on the first screen module 2 and the second screen module 3. The limit rotation mechanism 1a cooperates with the elastic buffer mechanism 4 to drive the first screen module 2 and the second screen module 3 to achieve synchronous rotation that limits, provides torque and plays a buffering role. The connecting parts of the second synchronous rotation mechanism 1d are respectively installed on the first shrimp shell member 11, the first screen module 2 and the second screen module 3, and the connecting parts of one of the synchronous sliding mechanisms 1e are respectively installed on the second shrimp shell member 12 and the first On the screen module 2, the connecting part of another synchronous sliding mechanism 1e is respectively installed on the third shrimp shell member 13 and the second screen module 3, and the synchronous sliding mechanism 1e cooperates with the second synchronous rotation mechanism 1d to realize the synchronous linkage of the five shrimp shell members and the two screen modules, wherein the first screen module 2 and the second screen module 3 are respectively fixed with the first cover plate 201 and the second cover plate 301 by screws, and the first cover plate 201 and the elastic buffer mechanism 4 are provided with a first groove 202 at the position opposite to the first cover plate 201, and the second cover plate 301 and the elastic buffer mechanism 4 are provided with a second groove 302 at the position opposite to the first cover plate 201. The first cover plate 201 and the second cover plate 301 can ensure the flatness and uniformity of the inner side of the screen module, which is beneficial to the layout and installation of the modules in the screen module, and the first groove 202 and the second groove 302 can provide space for the boss to move when it slides in the slide groove.

[0030] Furthermore, when the hinge 1 rotates, the distance and angle between the rotating components inside the first synchronous rotating mechanism 1c and the second synchronous rotating mechanism 1d are automatically adjusted, and the internal components of the synchronous sliding mechanism 1e and the crescent module 1b slide relatively to each other, so as to achieve a stable rotation relationship and rotation path between the shrimp shell parts. When the hinge 1 is closed, the rotating components inside the two rotating mechanisms are closed toward the corresponding shrimp shell parts, saving the internal space of the hinge. The sliding mechanism 1e and the crescent module 1b limit the closing degree of the shrimp shell parts and the screen module, ensuring the miniaturization of the hinge 1 structure. At the same time, the rotating parts inside the hinge 1 are symmetrically arranged, which makes the structure of the hinge 1 simpler, facilitates the production of the hinge 1 and increases the service life of the hinge 1.

[0031] Furthermore, the limiting rotation mechanism 1a includes a Y-shaped fixed boss 1a1 installed on the top of the first shrimp shell member 11, and the openings on both sides of the Y-shaped fixed boss 1a1 are rotatably connected with a rotating shaft, and one end of the two rotating shafts is fixedly connected with a toothed wing 1a2, and one end of the two toothed wing 1a2 is meshed and connected to form a meshing portion, and the other end of the toothed wing 1a2 is slidably connected to a slide groove provided in the U-shaped shell 401 of the elastic buffer mechanism 4 through a fixedly connected boss, and the slide groove limits the sliding path of the boss, and is used for the contraction of the toothed wing 1a2 when the limiting rotation mechanism 1a is closed, and the elastic A plurality of buffer springs 402 fixedly connected inside the buffer mechanism 4 are fixedly connected to one side of the boss. When the toothed wing 1a2 is subjected to the force of the first screen module 2 and the second screen module 3, the toothed wing 1a2 can be rotated through the rotating shaft. The corresponding two toothed wings 1a2 are meshed and connected through a rack at one end. When the toothed wing 1a2 rotates, the meshed rack is used to provide torque and generate mechanical rotation feedback to prevent the user from applying excessive force when rotating the two screen modules. The slide groove limits the sliding path of the boss and also serves to compensate for the distance when the toothed wing 1a2 rotates.

[0032] Furthermore, the crescent module 1b includes a Y-shaped crescent protrusion 1b1 fixedly installed on the top of the first shrimp shell member 11. The two sides of the Y-shaped crescent protrusion 1b1 are cooperated and connected with two first crescent groove members 1b2 respectively installed on the second shrimp shell member 12 and the third shrimp shell member 13, so as to realize the synchronous rotation of the second shrimp shell member 12 and the third shrimp shell member 13 with the first shrimp shell member 11. The crescent module 1b can ensure that when the hinge rotates, it can play a certain limiting and synchronization role on the first shrimp shell member 11, the second shrimp shell member 12 and the third shrimp shell member 13, so as to ensure that the rotation center lines of the three shrimp shell members coincide with their corresponding center lines.

[0033] Furthermore, the first synchronous rotation mechanism 1c includes a first fixed boss B1c2 and a first fixed boss A1c1 respectively mounted on the second shrimp shell member 12 and the third shrimp shell member 13, and the grooves on the tops of the first fixed boss B1c2 and the first fixed boss A1c1 are smoothly connected with a rotation center axis, and one end of the rotation center axis of the first fixed boss A1c1 and the first fixed boss B1c2 is coaxially sleeved with two first connecting members 1c3, wherein one end of the two first connecting members 1c3 is rotatably connected by a pin shaft, and one end of the other two first connecting members 1c3 is connected to the first crescent through two first connecting members 1c3. The pin shafts of the protrusions 1c5 are rotatably connected to the two first fixed supports 1c4 respectively, and the two first fixed supports 1c4 are respectively mounted on the fourth shrimp shell member 14 and the fifth shrimp shell member 15. The two first crescent protrusions 1c5 are cooperatively connected with the two second crescent groove members 1c6 respectively mounted on the fourth shrimp shell member 14 and the fifth shrimp shell member 15. The synchronous rotation mechanism is connected through a multi-link structure of a spatial linkage structure. When the hinge rotates, the distance between the structures connected by the connecting members is directly shortened, and the angle is adjusted automatically to absorb this part of the distance, while preventing the structural members connected to the synchronous rotation mechanism from being subjected to extrusion or tension.

[0034] Furthermore, the second synchronous rotation mechanism 1d includes a second fixed boss 1d1 fixedly mounted on the first shrimp shell member 11, a rotating center axis is smoothly connected in the groove on the top of the second fixed boss 1d1, one end of the rotating center axis is coaxially sleeved with two second connecting members, the two second connecting members are rotatably connected to two second fixed supports 1d2 mounted on the second shrimp shell member 12 and the third shrimp shell member 13 through pins, and the second synchronous rotation mechanism 1d is used in conjunction with the first synchronous rotation mechanism 1c to further increase the synchronization of the rotation of the five shrimp shell members of the hinge 1.

[0035] Furthermore, multiple synchronous sliding mechanisms 1e are provided, and two synchronous sliding mechanisms 1e are used in combination, wherein one synchronous sliding mechanism 1e includes a sliding fixed boss 1e2 installed on one side of the first screen module 2, and an arc groove opened on one side of the sliding fixed boss 1e2 is slidably connected to one end of an L-shaped sliding support frame 1e1 installed on the second shrimp shell component 12, wherein the other synchronous sliding mechanism 1e includes a sliding fixed boss 1e2 installed on one side of the second screen module 3, and an arc groove opened on one side of the sliding fixed boss 1e2 is slidably connected to one end of an L-shaped sliding support frame 1e1 installed on the third shrimp shell component 13, and the synchronous sliding mechanism 1e is used to guide and limit the rotation of the second shrimp shell component 12 and the first screen module 2 and the rotation of the third shrimp shell component 13 and the second screen module 3.

[0036] Furthermore, when the first shrimp shell component 11, the second shrimp shell component 12, the third shrimp shell component 13, the fourth shrimp shell component 14 and the fifth shrimp shell component 15 realize synchronous rotation through the first synchronous rotation mechanism 1c, the second synchronous rotation mechanism 1d, the crescent module 1b, the rotation limiting mechanism 1a and the synchronous sliding mechanism 1e, each shrimp shell component rotates around its own center to reduce the tension and pressure on the flexible screen during the movement process.

[0037] Specifically, when the mobile phone needs to be opened, the first screen module 2 and the second screen module 3 are first pulled, and the first screen module 2 and the second screen module 3 provide torque through the meshing racks provided on the outer sides of one end of the two toothed wings 1a2 of the limiting rotation mechanism 1a, and the Y-shaped fixed boss 1a1 of the limiting rotation mechanism 1a acts on the first shrimp shell member 11 of the hinge 1, and at the same time, the convex column connected to the other end of the two toothed wings 1a2 of the limiting rotation mechanism 1a is slidably connected with the slide groove provided in the U-shaped shell 401 of the elastic buffer mechanism 4, and the slide groove limits and guides the sliding path of the convex column. The two corresponding buffer mechanisms 4 can drive the first screen module 2 and the second screen module 3 to rotate synchronously with the first shrimp shell 11 as the center. The two meshing toothed wings 1a2 of the rotation limit mechanism 1a can play a certain limiting role when the hinge 1 rotates, and provide mechanical rotation feedback to the user's hand to avoid damage to the flexible screen. When the first screen module 2 and the second screen module 3 rotate, they can also drive the second shrimp shell 12 and the third shrimp shell 13 to rotate synchronously through the synchronous sliding mechanism 1e. The rotating second shrimp shell member 12 and the third shrimp shell member 13 are driven by the first synchronous rotation mechanism 1c, and the first connecting member 1c3 and the pin shaft of the first synchronous rotation mechanism 1c drive the first crescent protrusion member 1c5 and the second crescent groove member 1c6 to drive the fourth shrimp shell member 14 and the fifth shrimp shell member 15 to perform synchronous linkage around their respective centers. When the second shrimp shell member 12 and the third shrimp shell member 13 rotate, they can realize synchronous linkage around their respective centers under the action of the second fixed support frame 1d2 of the second synchronous rotation mechanism 1d. The crescent module 1b can ensure that the hinge rotates 1 When moving, it can play a certain limiting and synchronizing role on the first shrimp shell component 11, the second shrimp shell component 12 and the third shrimp shell component 13, ensuring that the rotation center lines of the three shrimp shell components coincide with their corresponding center lines, and cooperating with the first crescent protrusion component 1c5 and the second crescent groove component 1c6 to realize that the rotation of the five shrimp shells all rotates around their respective centers. When the first screen module 2 and the second screen module 3 are fully opened (at an angle of 180 degrees), the buffer spring 402 is used to elastically tighten the two screen modules to avoid the two screen modules from rotating on their own, which would cause poor user experience.

[0038] It should be supplemented that when the mobile phone is opened or closed, the total length of the outer sides of the first shrimp shell member 11, the second shrimp shell member 12, the third shrimp shell member 13, the fourth shrimp shell member 14 and the fifth shrimp shell member 15 remains unchanged, and always remains smooth, and supports the flexible screen.
