Description

Technical Field

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

[0002] In the current large-screen folding structure solutions on the market, the torque of a single set of torque modules is relatively small, usually between 5 and 10 N·m, which results in insufficient stability in actual applications. Due to insufficient torque, the screen is prone to deformation, offset, etc. when used frequently or under external forces, affecting the user experience and the device lifespan.

[0003] To meet the usage requirements of large-screen devices, basically three to four sets of torque modules need to work together to provide sufficient support and anti-deformation ability. By increasing the number of torque modules, although the overall structural stability and durability can be improved, the design of multiple sets of torque modules increases the complexity and cost of the system. Not only more space is required to arrange these modules, but also the coordination and cooperation between multiple torque modules increase the difficulty of system debugging and maintenance, further enhancing the overall complexity and cost. Summary of the Invention

[0004] In view of this, the present invention provides a torque control component for a foldable 3C device terminal, aiming to solve the problems existing in the current technology.

[0005] The present invention provides a torque control component for a foldable 3C device terminal, including a movable member that alternately moves between a flattened position and a folded position. At least two tilting force arms that linearly move in the second axis direction are slidably connected to each movable member. At least a part of the tilting force arms slidably connected to the movable member is movably connected to a linear motion shaft that linearly moves along the second axis. Each tilting force arm and the linear motion shaft respectively control the angle after the tilting force arm rotates around the linear motion shaft through a torque control group. At least a part of one set of the torque control groups is fixed to the linear motion shaft, and another set of the torque control groups is movably connected to the linear motion shaft and the torque control group abuts against an elastic member on the linear motion shaft.

[0006] In some embodiments of the present application, the two sets of torque control groups are symmetrically distributed about a first axis perpendicular to the second axis, and the tilting force arms linearly move between the at least part fixed to the linear motion shaft and the elastic member.

[0007] In some embodiments of the present application, the structures of the two sets of the torque control groups are the same, including a torque control cam and a torque control concave cam that are engaged with each other in a concave-convex manner. Any one of the torque control cam and the torque control concave cam is provided on the inclined force arm, and the remaining one is movably or fixedly provided on the linear motion axis.

[0008] In some embodiments of the present application, there are two movable members that are spaced apart, and there are two linear motion axes, and each linear motion axis is slidably connected to one of the movable members through the inclined force arm respectively.

[0009] In some embodiments of the present application, a torque control cam is respectively fixedly provided on each linear motion axis, and the two torque control cams are integrally formed and are on the side away from the elastic member.

[0010] In some embodiments of the present application, a cam limiting member is respectively fixedly provided on each linear motion axis, and the torque control cam abuts against the cam limiting member.

[0011] In some embodiments of the present application, a card slot is respectively provided on each linear motion axis, the cam limiting member is clamped in the card slot, and the two cam limiting members are integrally formed.

[0012] In some embodiments of the present application, a torque control cam is respectively movably connected to each linear motion axis, the two torque control cams are integrally formed, and the elastic member acts on the outside of the torque control cam.

[0013] In some embodiments of the present application, a space is formed between the two inclined force arms that are slidably connected to the same movable member, and the torque control assembly further includes a driving member that linearly moves along the second axis, and the driving member has a clearance canceling portion that extends into the space between the two inclined force arms.

[0014] In some embodiments of the present application, the driving member is slidably connected to the base, one end of the linear motion axis away from the elastic member is movably connected to the base, and each movable member is respectively movably connected to a rotary driving force arm hinged to the base in the first axis direction. The two opposite sides of the driving member are respectively movably matched with the rotary driving force arm. When the rotary driving force arm rotates, it can drive the driving member to linearly move so that the linear motion axis linearly moves along the second axis.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: In the present invention, each movable member is respectively slidably connected to at least two inclined force arms of the torsion control assembly, and each movable member is slidably connected to two sets of torsion control assemblies through the inclined force arms. Therefore, the two movable members are at least slidably connected to eight inclined force arms, and the eight inclined force arms are angle-adjusted through the torsion control group.

Detailed implementation manners

[0018] Hereinafter, exemplary embodiments of the present disclosure will be described in more detail 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 completely 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. Hereinafter, the present invention will be described in detail with reference to the drawings and in combination with the embodiments.

[0019] Embodiment 1

[0020] Refer 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. Two sets of torque control components are 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 arms 31 of the torque control components respectively. The two sets of torque control components move towards each other or away from each other along the second axis Y under the drive of a synchronous drive component, and the rotating driving arm 41 of the synchronous drive component is slidably connected to the corresponding movable member 2 in the first axis X direction.

[0021] It can be understood that in this embodiment, the rotating driving 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.

[0022] It can be understood that in this embodiment, the synchronous drive component is also responsible for driving the two sets of torque control components to move towards each other 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 torque control components through the rotating driving arm 41, ensuring that the two sets of torque control components can move towards each other or away from each other along the second axis Y.

[0023] It can be understood that since the rotational driving force arm 41 of the synchronous driving component and the inclined force arm 31 of the torsion control component 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.

[0024] In a specific embodiment of the present application, the movable member 2 alternately moves between the folded position and the flattened position. When the synchronous driving component drives the torsion control components 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 driving component drives the torsion control components to move away from each other and the movable member 2 moves to the flattened position.

[0025] In a specific embodiment of the present application, the inclined force arm 31 of the torsion control component and the rotational driving force arm 41 are distributed at an angle.

[0026] Specifically, the inclined force arms 31 on both sides of the rotational driving force arm 41 corresponding to the same movable member 2 and slidably connected in the second axis Y direction are distributed at an angle with an opening towards the end away from the base 1.

[0027] It can be understood that when the movable member 2 alternately moves between the folded position and the flattened position, the two sets of torsion control components are driven to move towards each other or in opposite directions by the synchronous driving component. When the two sets of torsion control components move towards each other, the inclined force arms 31 of the two sets of torsion control components slidably connected to the same movable member 2 are driven to move towards each other. Since the inclined force arms 31 of the two sets of torsion control components corresponding to the same movable member 2 and slidably connected on both sides are distributed at an angle with an opening towards the end away from the base 1, the inclined force arms 31 of the two sets of torsion control components corresponding to the same movable member 2 apply a force to the movable member 2 in the first axis X direction away from the base 1, that is, the two movable members 2 slide relatively outward in the first axis X direction. When the two sets of torsion control components move in opposite directions, the inclined force arms 31 of the two sets of torsion control components 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 components corresponding to the same movable member 2 and slidably connected apply a force to the movable member 2 in the first axis X direction towards the base 1, that is, the two movable members 2 slide relatively inward in the first axis X direction.

[0028] It can be understood that in this embodiment, the two sets of torsion control components are driven to move towards each other or in opposite directions by the synchronous driving component, 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.

[0029] In a specific embodiment of the present application, the torque control assembly includes: at least part of the inclined force arm 31 slidably connected to the movable member 2 and at least part of the linear motion axis 32 that linearly moves along the second axis Y. Each inclined force arm 31 and the linear motion axis 32 respectively control the angle after the inclined force arm 31 rotates around the linear motion axis 32 through a torque control group. At least part of one group of torque control groups is fixed to the linear motion axis 32, and the other group of torque control groups is movably connected to the linear motion axis 32 and the torque control group abuts against the elastic member 34 on the linear motion axis 32.

[0030] In a specific embodiment of the present application, the inclined force arm 31 linearly moves between at least part fixed to the linear motion axis 32 and the elastic member 34. The two groups of torque control groups are symmetrically distributed along the first axis X perpendicular to the second axis Y. One end of the linear motion axis 32 far from the elastic member 34 is movably connected to the base 1.

[0031] Specifically, in this embodiment, one end of the linear motion axis 32 in the torque control assembly far from the elastic member 34 is movably connected to the base 1. The linear motion axis 32 provides a moving path for the torque control assembly when the torque control assembly moves in the opposite or same direction along the second axis Y under the drive of the synchronous drive assembly. When the torque control assembly moves in the opposite 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 opposite direction on the linear motion axis 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 axis 32.

[0032] 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 axis 32. One part is fixed to the linear motion axis 32, and the other part is movably connected to the linear motion axis 32 and interacts with the elastic member 34. The elastic member 34 abuts against the torque control group on the linear motion axis 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.

[0033] Specifically, the elastic member 34 refers to a material or device with elasticity, preferably a spring.

[0034] It can be understood that in this embodiment, the tilting 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 a part of the tilting 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 tilting lever arm 31. The sliding connection provides degrees of freedom for the tilting lever arm 31, enabling it to move within a certain range, while the linear motion axis 32 provides a stable reference benchmark for the rotation of the tilting lever arm 31. The linear motion axis 32 moves linearly in the second axis Y direction, thereby driving the connected tilting lever arm 31 to move in the second axis Y direction. At the same time, the tilting lever arm 31 is slidably connected to the movable member 2, ensuring that the tilting lever arm 31 is not restricted by the movable member 2 when moving in the second axis Y direction.

[0035] It can be understood that in this embodiment, the torque control assembly realizes the flexible movement of the tilting 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 ways of fixed and movable connection to precisely adjust the angle of the tilting lever arm 31, thereby achieving fine control of the torque.

[0036] 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.

[0037] 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 the error during the assembly process and improve the stability and consistency of the hinge.

[0038] 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 a tilting 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 engaged with each other in a concave-convex manner. Either the torque control cam 35 or the torque control concave cam 36 is arranged on the tilting lever arm 31, and the remaining one is movably arranged or fixedly arranged on the linear motion axis 32.

[0039] It can be understood that in this embodiment, the torque control group realizes the precise angle adjustment of the inclined lever arm 31. Specifically, the moving 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.

[0040] It can be understood that in this embodiment, each moving member 2 is respectively slidably connected to at least two inclined lever arms 31 of the torque control assembly, and each moving member 2 is slidably connected to two groups of torque control assemblies through the inclined lever arms 31. Therefore, the two moving 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 torque control group. That is, in this embodiment, by slidably connecting each moving member 2 to at least two inclined lever arms 31 and ensuring that each group of torque control assemblies is connected to two groups of moving members 2, multi-point connection and distributed torque transmission are realized, enabling a single group of hinge mechanisms to generate greater torque and improving the stability and reliability of the overall system.

[0041] Specifically, the setting methods of the torque control group in this embodiment include the following two types: The first method: A torque control cam 35 is respectively fixedly arranged on each linear motion axis 32, and two torque control cams 35 are connected as an integral structure and are on the side far from the elastic member 34. A torque control cam 35 is respectively movably connected on each linear motion axis 32, and two torque control cams 35 are connected as an integral structure and the elastic member 34 acts on the outside of the torque control cam 35.

[0042] The second method: A cam limiting member 37 is respectively fixedly arranged on each linear motion axis 32, and the torque control cam 35 abuts against the cam limiting member 37. A card slot 321 is respectively provided on each linear motion axis 32, the cam limiting member 37 is clamped in the card slot 321, and two cam limiting members 37 are connected as an integral structure. A torque control cam 35 is respectively movably connected on each linear motion axis 32, and two torque control cams 35 are connected as an integral structure and the elastic member 34 acts on the outside of the torque control cam 35.

[0043] In a specific embodiment of the present application, the synchronous drive assembly includes a rotating driving lever arm 41 and a driving member 42. Each moving member 2 is respectively movably connected to a rotating 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 rotating driving lever arm 41 on opposite sides to drive the torque control assembly to move towards or away from each other along the second axis Y.

[0044] It can be understood that in this embodiment, the driving member 42 cooperates with the rotating driving force arm 41 to push the movable member 2 to move.

[0045] It can be understood that in this embodiment, the rotating driving force arm 41 is used to convert the rotational motion into a 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 rotating driving force arm 41, precise control of the torque is achieved.

[0046] Specifically, the driving member 42 is arranged on the base 1, and through cooperation with the rotating driving force arm 41, it pushes the movable member 2 to move towards or away from each other along the second axis Y direction.

[0047] In a specific embodiment of the present application, the rotating driving force arms 41 movably connected to the movable member 2 are distributed at intervals, and the rotating driving force arms 41 connected to the movable member 2 are symmetrically distributed with respect to the second axis Y.

[0048] In a specific embodiment of the present application, each movable member 2 is movably connected to two rotating driving force arms 41 respectively in the first axis X direction.

[0049] It can be understood that the rotating 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 rotating 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 rotating driving force arms 41 respectively in the first axis X direction, 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 design of symmetrical distribution, control can be simplified, and reliability and durability can be improved.

[0050] In a specific embodiment of the present application, a force arm groove 21 for inserting the rotating 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.

[0051] 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 rotating driving force arm 41 and the inclined force arm 31, so that the rotating 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 grooves 21 and the force arm inclined grooves 22 not only provide physical support, but also ensure the stability and accuracy of the force arms during movement.

[0052] 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 torsion 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.

[0053] Specifically, in this embodiment, the clearance cancellation portion 421 of the driving member 42 is disposed between the portions where the two inclined force arms 31 are connected to the linear movement axis 32, and the linear movement axis 32 passes through the clearance cancellation portion 421 of the driving member 42 and is slidably connected to the base 1.

[0054] 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 greater than 90°, enabling the hinge to have a large movement range and flexibility. Since the rotational driving force arm 41 is located between the torsion 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 torsion 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 therein. The linear movement axis 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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 to 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 to achieve synchronous bidirectional driving. It not only has a simple structure and is easy to manufacture, but also significantly reduces the production and maintenance costs.
