Description

Technical Field

[0001] The present invention relates to the technical field of foldable 3C devices, and more particularly, to a hinge mechanism for a foldable 3C device terminal. Background Art

[0002] Currently, the core principle of a folding hinge is to achieve multi-point synchronous bending of the screen through a precision mechanical structure while maintaining flatness and durability. Based on the "drop-shaped" folding concept, sufficient space is reserved at the screen bending area to form a drop-shaped arc, avoiding excessive stress on the screen during folding.

[0003] In the related inner folding hinge mechanism in the prior art, to create the drop space, a "door panel direct drive" structure design is generally adopted. The hinge door panel is directly driven by the movement of the arc arm, and the arc of the arc arm expands the space to form a drop space, thus ensuring that the plane is not squeezed or stretched.

[0004] However, when solely relying on the arc arm to form the drop space, a too large arc of the arc arm will increase the mechanical stress concentration of the hinge structure, increase the thickness of the device in the folded state, cause the screen material to bear greater tensile stress, increase the movement clearance of the moving parts, and damage the integrity of the waterproof sealing system. Summary of the Invention

[0005] In view of this, the present invention provides a hinge mechanism for a foldable 3C device terminal, aiming to solve the above technical problems.

[0006] The present invention provides a hinge mechanism for a foldable 3C device terminal, including a base and at least two spaced-apart movable members. Each movable member is respectively movably connected in a first axial direction to a rotary driving force arm hinged to the base, and each movable member is also respectively movably connected to two sets of torsion control components that linearly move on a second axis perpendicular to the first axis X of the base. The inclined force arms of the torsion control components are distributed at an angle to the rotary driving force arm. A driving member is provided on the base and is movably engaged with the rotary driving force arm on opposite sides respectively to drive the torsion control components to move towards or away from each other along the second axis. When the driving member and the rotary driving force arm are movably engaged and the movable members are in the folded position, a conical space is formed between the two movable members.

[0007] In some embodiments of the present application, the movement angle of the movable member from the flattened position to the folded position when the driving member and the rotary driving force arm are movably engaged is greater than 90°.

[0008] In some embodiments of the present application, the rotary driving force arm is located between the two sets of torsion control components.

[0009] In some embodiments of the present application, two of the rotational driving force arms are respectively movably connected to each of the movable members in the first axis direction.

[0010] In some embodiments of the present application, the rotational driving force arms movably connected to the movable members are spaced apart, and the rotational driving force arms connected to the movable members are symmetrically distributed about the second axis.

[0011] In some embodiments of the present application, each set of the torsion control components respectively has two of the inclined force arms movably connected to the corresponding movable members.

[0012] In some embodiments of the present application, a force arm slot for inserting the rotational driving force arm is provided on the movable member, and a force arm inclined slot for inserting the inclined force arm is provided on the movable member.

[0013] In some embodiments of the present application, each of the rotational driving force arms is respectively hinged to the base through a hinge portion, there are two of the driving members and they are distributed along the second axis, a space for accommodating at least part of the driving members is formed between the two hinge portions, and at least part of the opposite sides of each of the driving members and at least part of the outer peripheral surface of the hinge portion are movably connected through a helical gear transmission structure.

[0014] In some embodiments of the present application, the helical gear transmission structure includes a first helical tooth portion and a second helical tooth portion provided on the outer peripheral surface of the hinge portion, first helical tooth mating portions meshing with the first helical tooth portion are respectively provided on the opposite sides of one of the driving members, and second helical tooth mating portions meshing with the second helical tooth portion are respectively provided on the opposite sides of the other driving member.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: In the present invention, two sets of torsion control components are driven to move towards each other or in opposite directions through the rotational driving force arms and the driving members, thereby realizing relative sliding between the two movable members. When the two movable members slide outwards relative to each other, a tapered space is formed between them and the base. This design effectively avoids the problem of insufficient screen space caused by folding of 3C device terminals. At the same time, the formation of the tapered space can ensure that the screen will not be squeezed or stretched during the entire bending process, thereby maintaining the integrity and display effect of the screen. On the contrary, when the two movable members slide inwards relative to each other, they will gradually flatten with the base, further optimizing the use experience and portability of the device. The present invention not only improves the flexibility of the device hinge mechanism, but also significantly improves the user experience, especially in scenarios that require frequent folding and unfolding, such as 3C devices like tablet computers and laptop computers.

[0016] On the other hand, the present application also provides a foldable 3C device terminal, and the foldable 3C device terminal includes the hinge mechanism of a foldable 3C device terminal as described above.

[0017] It can be understood that a foldable 3C device terminal in this embodiment has the same beneficial effects as the hinge mechanism of a foldable 3C device terminal, and will not be elaborated here. Description of the Drawings

[0020] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be fully conveyed to those skilled in the art. It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0021] Embodiment 1

[0022] Referring to Figure 1-8 , this embodiment provides a hinge for a foldable 3C device, including a base 1 and at least two movable members 2 spaced apart in the first axis X direction. There are two sets of torsion control components movably connected to the base 1 along the second axis Y direction, and each movable member 2 is slidably connected to at least two inclined force arms 31 of the torsion control components respectively. The two sets of torsion control components move towards or away from each other along the second axis Y under the drive of a synchronous drive component, and the rotational driving force arm 41 of the synchronous drive component is slidably connected to the corresponding movable member 2 in the first axis X direction.

[0023] It can be understood that in this embodiment, the rotational driving force arm 41 of the synchronous drive component is slidably connected to the corresponding movable member 2 in the first axis X direction. The two movable members 2 are spaced apart on both sides of the base 1 along the first axis X direction. When the two movable members 2 rotate relatively inwardly, the folding movement of the hinge is realized. When the two movable members 2 rotate relatively outwardly, the flattening movement of the hinge is realized.

[0024] It can be understood that in this embodiment, the synchronous drive component is also responsible for driving the two sets of torsion control components to move towards or away from each other along the second axis Y direction. The synchronous drive component transmits the rotational driving force provided by the two movable members 2 to the torsion control components through the rotational driving force arm 41, ensuring that the two sets of torsion control components can move towards or away from each other along the second axis Y.

[0025] It can be understood that since the rotational driving force arm 41 of the synchronous drive component and the inclined force arms 31 of the torsion control components are both slidably connected to the corresponding movable member 2 in the first axis X direction, the sliding connection method allows the movable member 2 to have a free movement space in the first axis X direction, realizing the flexible movement and adjustment of the movable member 2 in the first axis X direction.

[0026] In a specific embodiment of the present application, the movable member 2 moves alternately between the folded position and the flattened position. When the synchronous drive assembly drives the torsion control assembly to move towards each other and the movable member 2 is in the folded position, a conical space 6 is formed between the two movable members 2; when the synchronous drive assembly drives the torsion control assembly to move away from each other, the movable member 2 moves to the flattened position.

[0027] In a specific embodiment of the present application, the inclined force arm 31 of the torsion control assembly and the rotational driving force arm 41 are distributed at an angle.

[0028] Specifically, the rotational driving force arms 41 corresponding to the same movable member 2 and slidably connected are distributed at an angle with the inclined force arms 31 on both sides along the second axis Y, opening towards the end away from the base 1.

[0029] It can be understood that when the movable member 2 moves alternately between the folded position and the flattened position, the synchronous drive assembly drives the two sets of torsion control assemblies to move towards each other or in opposite directions. When the two sets of torsion control assemblies move towards each other, the inclined force arms 31 of the two sets of torsion control assemblies slidably connected to the same movable member 2 are driven to move towards each other. Since the inclined force arms 31 of the torsion control assemblies on both sides corresponding to the same movable member 2 are distributed at an angle opening towards the end away from the base 1, the inclined force arms 31 of the two sets of torsion control assemblies corresponding to the same movable member 2 apply a force to the movable member 2 away from the base 1 along the first axis X, that is, the two movable members 2 slide relatively outward along the first axis X. When the two sets of torsion control assemblies move in opposite directions, the inclined force arms 31 of the two sets of torsion control assemblies slidably connected to the same movable member 2 are driven to move in opposite directions, then the inclined force arms 31 of the two sets of torsion control assemblies corresponding to the same movable member 2 apply a force to the movable member 2 towards the base 1 along the first axis X, that is, the two movable members 2 slide relatively inward along the first axis X.

[0030] It can be understood that in this embodiment, the synchronous drive assembly drives the two sets of torsion control assemblies to move towards each other or in opposite directions, thereby realizing the relative sliding between the two movable members 2. When sliding relatively outward, a conical space 6 is formed between the two movable members 2 and the base 1. When sliding relatively inward, the two movable members 2 and the base 1 are flattened. The formation of the conical space 6 avoids the insufficient screen space caused by the folding of the 3C device terminal, and thus ensures that the screen is not squeezed or stretched during the entire bending process.

[0031] In a specific embodiment of the present application, the torque control assembly includes: at least a part of the inclined force arm 31 slidably connected to the movable member 2 is movably connected to a linear motion shaft 32 linearly moving along the second axis Y. Each inclined force arm 31 and the linear motion shaft 32 respectively control the angle after the inclined force arm 31 rotates around the linear motion shaft 32 through a torque control group. At least a part of one group of torque control groups is fixed to the linear motion shaft 32, and the other group of torque control groups is movably connected to the linear motion shaft 32 and the torque control group abuts against an elastic member 34 on the linear motion shaft 32.

[0032] In a specific embodiment of the present application, the inclined force arm 31 linearly moves between at least a part fixed to the linear motion shaft 32 and the elastic member 34. The two groups of torque control groups are symmetrically distributed along a first axis X perpendicular to the second axis Y. One end of the linear motion shaft 32 away from the elastic member 34 is movably connected to the base 1.

[0033] Specifically, in this embodiment, one end of the linear motion shaft 32 in the torque control assembly away from the elastic member 34 is movably connected to the base 1. The linear motion shaft 32 provides a moving path for the torque control assembly when the torque control assembly moves in opposite or same directions along the second axis Y under the drive of the synchronous drive assembly. When the torque control assembly moves in opposite directions along the second axis Y, the inclined force arms 31 slidably connected to both sides of each movable member 2 along the second axis Y move in opposite directions on the linear motion shaft 32. When the torque control assembly moves in the same direction along the second axis Y, the inclined force arms 31 slidably connected to both sides of each movable member 2 along the second axis Y move in the same direction on the linear motion shaft 32.

[0034] Specifically, in this embodiment, the torque control group is responsible for adjusting the angle of the inclined force arm 31 rotating around the linear motion shaft 32. One part is fixed to the linear motion shaft 32, and the other part is movably connected to the linear motion shaft 32 and interacts with the elastic member 34. The elastic member 34 abuts against the torque control group on the linear motion shaft 32 and assists in adjusting the angle of the inclined force arm 31 through its elastic characteristics to ensure the stability and accuracy of the adjustment.

[0035] Specifically, the elastic member 34 refers to a material or device with elasticity, preferably a spring.

[0036] It can be understood that in this embodiment, the inclined lever arm 31 is used to transmit and adjust the torque. Through the action of the torque control group, it can rotate around the linear motion axis 32, thereby achieving precise control of the torque. At least part of the inclined lever arm 31 is slidably connected to the movable member 2, allowing it to move in a specific direction. The linear motion axis 32 is an axis that moves linearly along the second axis Y, providing a fixed reference point and a motion path for the inclined lever arm 31. The sliding connection provides degrees of freedom for the inclined lever arm 31, enabling it to move within a certain range, and the linear motion axis 32 provides a stable reference benchmark for the rotation of the inclined lever arm 31. The linear motion axis 32 moves linearly in the second axis Y direction, thereby driving the connected inclined lever arm 31 to move in the second axis Y direction. At the same time, the inclined lever arm 31 is slidably connected to the movable member 2, ensuring that the inclined lever arm 31 is not restricted by the movable member 2 when moving in the second axis Y direction.

[0037] It can be understood that in this embodiment, the torque control assembly realizes the flexible movement of the inclined lever arm 31 through the cooperation of the sliding connection and the linear motion axis 32. The torque control group works in cooperation with the elastic member 34 through two methods of fixed and movable connection to precisely adjust the angle of the inclined lever arm 31, thereby achieving fine control of the torque.

[0038] Specifically, a washer 38 is movably arranged on each linear motion axis 32. The washer 38 is located at one end of the elastic member 34 away from the torque control group, and the two washers 38 are connected as an integral structure.

[0039] It can be understood that in this embodiment, by installing the washer 38 on each linear motion axis 32 and matching it with the elastic member 34 and the torque control group, it can ensure that the hinge can maintain the best performance under different load conditions, extend the service life of the device, and reduce the maintenance cost. Designing the washer 38 as an integral structure can reduce errors during the assembly process and improve the stability and consistency of the hinge.

[0040] In a specific embodiment of the present application, there are two linear motion axes 32, and each linear motion axis 32 is slidably connected to a movable member 2 through an inclined lever arm 31. The structures of the two torque control groups are the same, including a torque control cam 35 and a torque control concave cam 36 that are in concave-convex fit with each other. Either the torque control cam 35 or the torque control concave cam 36 is arranged on the inclined lever arm 31, and the remaining one is movably arranged or fixedly arranged on the linear motion axis 32.

[0041] It can be understood that in this embodiment, the torsion control group realizes the precise angle adjustment of the inclined lever arm 31. Specifically, the movable member 2 drives the inclined lever arm 31 to rotate on the linear motion axis 32, so that the control cam and the control concave cam rotate relative to each other. The inclined lever arm 31 moves on the linear motion axis 32, and the elastic member 34 is forced to perform a compression motion. When the rotation of the inclined lever arm 31 on the linear motion axis 32 ends, the restoring force of the elastic member 34 causes the control cam and the control concave cam to be relatively clamped, realizing angle fixation.

[0042] It can be understood that in this embodiment, each movable member 2 is respectively slidably connected to at least two inclined lever arms 31 of the torsion control assembly, and each movable member 2 is slidably connected to two groups of torsion control assemblies through the inclined lever arms 31. Therefore, the two movable members 2 are at least slidably connected to eight inclined lever arms 31, and the eight inclined lever arms 31 realize angle adjustment through the torsion control group. That is, in this embodiment, by slidably connecting each movable member 2 to at least two inclined lever arms 31 and ensuring that each group of torsion control assemblies is connected to two groups of movable members 2, multi-point connection and distributed torsion transmission are realized, enabling a single group of hinge mechanisms to generate greater torsion and improving the stability and reliability of the overall system.

[0043] Specifically, there are the following two ways to set up the torsion control group in this embodiment: The first way: A torsion control cam 35 is respectively fixedly arranged on each linear motion axis 32, and two torsion control cams 35 are connected as an integral structure and are on the side far from the elastic member 34. A torsion control cam 35 is respectively movably connected to each linear motion axis 32, and two torsion control cams 35 are connected as an integral structure and the elastic member 34 acts on the outside of the torsion control cam 35.

[0044] The second way: A cam limiting member is respectively fixedly arranged on each linear motion axis 32, and the torsion control cam 35 abuts against the cam limiting member. A card slot is respectively provided on each linear motion axis 32, the cam limiting member is stuck in the card slot, and two cam limiting members are connected as an integral structure. A torsion control cam 35 is respectively movably connected to each linear motion axis 32, and two torsion control cams 35 are connected as an integral structure and the elastic member 34 acts on the outside of the torsion control cam 35.

[0045] In a specific embodiment of the present application, the synchronous drive assembly includes a rotational driving lever arm 41 and a driving member 42. Each movable member 2 is respectively movably connected to a rotational driving lever arm 41 hinged to the base 1 in the first axis X direction, and a driving member 42 is provided on the base 1 and is movably matched with the rotational driving lever arm 41 on both opposite sides to drive the torsion control assembly to move towards or away from each other along the second axis Y.

[0046] It can be understood that in this embodiment, the driving member 42 cooperates with the rotary driving force arm 41 to push the movable member 2 to move.

[0047] It can be understood that in this embodiment, the rotary driving force arm 41 is used to convert rotary motion into linear motion, so as to drive the torque control assembly to move through the driving member 42. Under the action of the driving member 42, the torque control assembly moves towards or away from each other along the second axis Y direction, and through the cooperation of the rotary driving force arm 41, precise control of the torque is achieved.

[0048] Specifically, the driving member 42 is arranged on the base 1, and through cooperation with the rotary driving force arm 41, it pushes the movable member 2 to move towards or away from each other along the second axis Y direction.

[0049] In a specific embodiment of the present application, the rotary driving force arms 41 movably connected to the movable member 2 are distributed at intervals, and the rotary driving force arms 41 connected to the movable member 2 are symmetrically distributed with respect to the second axis Y.

[0050] In a specific embodiment of the present application, each movable member 2 is movably connected to two rotary driving force arms 41 in the first axis X direction respectively.

[0051] It can be understood that the rotary driving force arms 41 are distributed at intervals on the movable member 2 and are symmetrically distributed with respect to the second axis Y. By distributing the rotary driving force arms 41 at intervals and symmetrically on the movable member 2, uniform transmission of force and balance of the system can be ensured. At the same time, each movable member 2 is movably connected to two rotary driving force arms 41 in the first axis X direction respectively, further enhancing the flexibility and response speed of the hinge, not only improving the mechanical efficiency, but also reducing vibration and wear caused by asymmetric force distribution. In addition, through the symmetric distribution design, control can be simplified, and reliability and durability can be improved.

[0052] In a specific embodiment of the present application, a force arm groove 21 for inserting the rotary driving force arm 41 is provided on the movable member 2, and a force arm inclined groove 22 for inserting the inclined force arm 31 is provided on the movable member 2.

[0053] It can be understood that in this embodiment, special force arm grooves 21 and force arm inclined grooves 22 are provided on the movable member 2, which are respectively used to accommodate the rotary driving force arm 41 and the inclined force arm 31, so that the rotary driving force arm 41 and the inclined force arm 31 can accurately move within the predetermined path or angle range of the force arm groove 21 and the force arm inclined groove 22, thereby realizing effective driving of other components. The force arm groove 21 and the force arm inclined groove 22 not only provide physical support, but also ensure the stability and accuracy of the force arm during movement.

[0054] In a specific embodiment of the present application, the driving member 42 and the rotational driving force arm 41 are movably engaged such that the movement angle of the movable member 2 from the flattened position to the folded position is greater than 90°; the rotational driving force arm 41 is located between two sets of torque control components; a space is formed between two inclined force arms 31 slidably connected to the same movable member 2, and the driving member 42 has a clearance cancellation portion 421 extending into the space between the two inclined force arms 31.

[0055] Specifically, in this embodiment, the clearance cancellation portion 421 of the driving member 42 is provided between the portions where the two inclined force arms 31 are connected to the linear motion shaft 32, and the linear motion shaft 32 passes through the clearance cancellation portion 421 of the driving member 42 and is slidably connected to the base 1.

[0056] It can be understood that in this embodiment, through the cooperation of the driving member 42 and the rotational driving force arm 41, the movable member 2 can perform a movement of more than 90°, enabling the hinge to have a larger movement range and flexibility. Since the rotational driving force arm 41 is located between the torque control components, it ensures that the rotational driving force arm 41 can convert the rotational driving force into a linear driving force to drive the two-sided torque control components to move towards or away from each other. A specific space is formed between the two inclined force arms 31 slidably connected to the same movable member 2, and the clearance cancellation portion 421 of the driving member 42 extends into it. The linear motion shaft 32 passes through the clearance cancellation portion 421 and is slidably connected to the base 1, which helps to reduce friction and vibration during movement and improve the overall performance of the hinge.

[0057] In a specific embodiment of the present application, each rotational driving force arm 41 is respectively hinged to the base 1 through a hinge portion. There are two driving members 42 distributed along the second axis Y. A space for accommodating at least a part of the driving member 42 is formed between the two hinge portions. At least a part of the opposite sides of each driving member 42 and at least a part of the outer peripheral surface of the hinge portion are movably connected through a helical gear transmission structure.

[0058] In a specific embodiment of the present application, the helical gear transmission structure includes a first helical tooth portion 412 and a second helical tooth portion 413 provided on the outer peripheral surface of the hinge portion. The opposite sides of one driving member 42 are respectively provided with first helical tooth mating portions 422 meshing with the first helical tooth portion 412, and the opposite sides of the other driving member 42 are respectively provided with second helical tooth mating portions 423 meshing with the second helical tooth portion 413.

[0059] Specifically, the linear motion shaft 32 in each torque control component is slidably connected to the base 1 and extends into the hinge portion where the rotary driving force arm 41 is hinged to the base 1. The rotary driving force arm 41 rotates around the base 1 on the linear motion shaft 32 and converts the rotary driving force into a linear driving force, thereby achieving flexible power transmission. The two driving members 42 are distributed along the second axis Y and are connected to the hinge portion of the rotary driving force arm 41 through a helical gear transmission structure. The helical gear transmission structure realizes power transmission through helical gears. The helical gear transmission structure includes a first helical tooth portion 412 and a second helical tooth portion 413 provided on the outer peripheral surface of the hinge portion. The helical tooth directions of the first helical tooth portion 412 and the second helical tooth portion 413 are opposite. When meshing with the first helical tooth mating portion 422 and the second helical tooth mating portion 423 of the two driving members 42, the two driving members 42 are driven to move towards each other or in opposite directions.

[0060] It can be understood that in this embodiment, by combining the rotary driving force arm 41, the hinge portion, the driving member 42, and the helical gear transmission structure, efficient and flexible power transmission is achieved. Among them, the rotary driving force arm 41 can effectively utilize the rotary motion, concentrate the power and transmit it to the hinge portion, ensuring the stability and efficiency of power transmission. The hinge portion transmits the power to the two driving members 42 through the helical gear transmission structure and drives the two driving members 42 to move towards each other or in opposite directions, realizing synchronous bidirectional driving. It not only has a simple structure and is easy to manufacture, but also significantly reduces the production and maintenance costs.
