Background Art

[0002] like Figure 1 As shown in the figure, it can be known that the hinge mechanism of the conventional electronic device applied to the flexible screen at least comprises: a fixed bracket 61, a swing arm 62, an elastic member 63 and a cam seat 64; wherein the fixed bracket 61 is provided with two pivoting parts 611, and the two pivoting parts 611 respectively penetrate a shaft 612; the two swing arms 62 are respectively provided with a pivoted part 621, and each pivoted part 621 is provided with a groove 622 that can be fitted on the pivoting part 611, and the two shafts 612 are respectively provided with a pivoted part 621, and the two shafts 612 are respectively provided with a pivoted part 621. The two cam seats 64 are respectively provided with corresponding cams on the swing arm member 62. By elastically engaging with the corresponding cams, the two swing arm members 62 can be positioned at a specific opening and closing angle (for example, 0 degrees, 90 degrees or 180 degrees) through the fixed bracket 61.

[0003] In the utility model case CN 220581489U, a hub and an electronic device using the hub are disclosed, which mainly pivot two virtual axis brackets to a first base; pivot two physical axis brackets to a second base; a synchronous member is provided between the first base and the second base; a synchronous bracket is provided between the virtual axis bracket and the physical axis bracket; a physical axis is provided on the outer side of the two second bases, penetrating the second base, the synchronous member and the first base; and a compression spring is provided on the physical axis, and the compression spring is pressed against the physical axis bracket and the synchronous bracket through a concave cam group; the physical axis bracket is acted upon by the concave cam group and can be linked to the virtual axis bracket through the synchronous bracket to pivot; in addition, each of the virtual axis brackets is provided with a groove, which can be fitted with a corresponding convex block provided on the main body of the plate body, and a through fixing portion is provided in the groove, and a corresponding convex point is provided on the convex block, which can be embedded in the fixing portion to form a positioning.

[0004] The above-mentioned hub structure with parallel virtual axis brackets and real axis brackets, the combination between the virtual axis bracket and the plate body, in actual application, because the virtual axis bracket is directly plugged into the protrusion on the main body through the groove, if only the stability of the combination is considered, the processing accuracy of the relevant structure must be improved to form a close and tight combination between the virtual axis bracket and the main body; however, higher processing accuracy is bound to increase processing costs at the same time, and tight fit will also increase the difficulty of assembly, resulting in production deficiencies and limitations.

[0005] On the other hand, reducing the processing accuracy for easy assembly will not only cause looseness between the virtual axis bracket and the main body due to the need to retain a combination gap, but also make the operation of the entire hub unstable or inaccurate due to the looseness; therefore, the combination of the virtual axis bracket and the main body faces a dilemma in terms of structural accuracy and manufacturing (processing) simplicity.

[0006] In view of the above-mentioned shortcomings of common hinge mechanisms in practical applications, the inventor has studied ways to improve these shortcomings, and finally produced the present utility model. Utility Model Content

[0059] Please refer to Figures 2 to 4 As shown, it can be known that the structure of the utility model mainly includes: a torque module 1, a rotating bracket 2 and an elastic clamping member 3; wherein the torque module 1 has two swing arm components 11 that can synchronously pivot relative to each other, each of the swing arm components 11 extends outwardly with a sleeved portion 12, and sleeved tracks 121 are provided on both sides of the sleeved portion 12.

[0060] In a feasible embodiment, the swing arm assembly 11 may be composed of a main swing arm 111 and a secondary swing arm 112 which are adjacent to each other, and a gap 113 is formed between the main swing arm 111 and the secondary swing arm 112 .

[0061] The two rotating brackets 2 are respectively provided with a sleeve portion 21 symmetrically recessed on the surface. The sleeve portion 21 is a groove with a small mouth and a large bottom, and the sleeve portion 21 forms an opening on both sides of the rotating bracket 2, so that the sleeved portion 12 (swing arm assembly 11) can be inserted horizontally through the opening for connection; sleeve grooves 211 corresponding to the sleeve track 121 are respectively provided on both sides of the sleeve portion 21, and at least one positioning portion 22 (which can be a convex point or a convex column) is provided on the bottom surface of the sleeve portion 21.

[0062] In a feasible embodiment, the rotating bracket 2 can be provided with at least one pivoted portion 23 beside the sleeve portion 21 as needed; the pivoted portion 23 can be pivoted to a preset pivot portion 51 on a rotating arc arm 5 via a pivot 53, and the two rotating arc arms 5 are respectively provided with a convex arc portion 52 at one end away from the pivot portion 51.

[0063] The two elastic fasteners 3 are respectively arranged transversely in each of the sleeve portions 21 along the insertion direction of the sleeved portion 12 (swing arm assembly 11), and a rib 31 (which can be an arc-shaped protrusion) is provided in the middle section of the elastic fastener 3, and a supporting portion 33 is formed on both sides of the rib 31. A positioned portion 32 (which can be a hole) that can be sleeved on the positioning portion 22 is provided on the rib 31, so that the elastic fastener 3 can be positioned in the sleeve portion 21, and the rib 31 contacts and presses against the bottom surface of the sleeve portion 21.

[0064] In a feasible embodiment, each support portion 33 is provided with a bent edge 331 on one side away from the rib 31 (i.e., the elastic clamping member 3 toward the two opening directions of the sleeve portion 21), and the bent edge 331 is bent toward the protruding direction of the rib 31 (i.e., the lower side in the figure).

[0065] In the structure of the present embodiment, an arc arm bracket 4 can be provided between the two rotating brackets 2 as needed. The arc arm bracket 4 partially covers the torque module 1, and a concave notch 41 is provided at the position corresponding to the two swing arm components 11, and a concave arc portion 42 that can fit and contact the convex arc portion 52 is provided on both sides of the arc arm bracket 4.

[0066] Please refer to Figures 5 to 7As shown, it can be known that when the utility model is assembled, the elastic clamping member 3 is combined with the positioning portion 22 (convex point or convex column) by the positioning portion 32 (hole), so that the elastic clamping member 3 can be horizontally positioned in the sleeve portion 21; then, the sleeved portion 12 (swing arm assembly 11) of the torque module 1 is inserted into the sleeve portion 21 through the opening, and the sleeve track 121 slides along the sleeve groove 211. At the same time, the sleeved portion 12 (swing arm assembly 11) can smoothly pass through the support portion 33 to the assembly positioning position by the guidance of the bent edge 331. At this time, the two supporting parts 33 of the elastic tightening member 3 respectively press against the bottom side of the sleeved part 12 (upward), and cooperate with the rib 31 to press against the bottom surface of the sleeve part 21 (downward), so that the sleeved part 12 (swing arm assembly 11) can be pushed up (upward), and the upper side of the sleeve groove 211 is pressed against the upper side of the sleeve groove 211, so that the gap between the sleeved combination of the swing arm assembly 11 (sleeved part 12) of the torque module 1 and the rotating bracket 2 (sleeving part 21) can be eliminated by elastic pressing, forming a stable elastic tightening and positioning between each other.

[0067] When the above structure is actually applied, when the two swing arm components 11 of the torque module 1 perform synchronous relative pivoting activities in the two concave notches 41 of the arc arm bracket 4, the rotating brackets 2 can be linked to rotate synchronously; at the same time, each rotating bracket 2 links the rotating arc arm 5, cooperates with the convex arc portion 52 to slide on the concave arc portion 42, and the rotating arc arm 5 can be pivoted relative to the arc arm bracket 4.

[0068] In the above structure of the utility model, when the swing arm assembly 11 of the torque module 1 is combined with the rotating bracket 2, the elastic clamping member 3 is used to press against the sleeve portion 21 and the sleeved portion 12 to form a clamping effect; therefore, during the production and processing of the sleeve portion 21 and the sleeved portion 12, a larger precision error and relatively poor tightness can be allowed, thereby effectively reducing the production cost; at the same time, a bent edge 331 is provided on the side of the supporting portion 33 of the elastic clamping member 3, which can guide the sleeved portion 12 (swing arm assembly 11) to pass smoothly through the elastic clamping member 3 (supporting portion 33), making the overall assembly more convenient.

[0069] In summary, the combined structure of the torque module of the hinge device of the utility model can indeed achieve the effect of saving processing costs by reducing the processing accuracy, and can form an easy-to-assemble and firmly combined structure between the torque module and the rotating bracket. It is indeed a novel and progressive creation, so an application for a utility model patent is filed in accordance with the law; however, the content of the above description is only a description of the preferred embodiment of the utility model, and all changes, modifications, alterations or equivalent substitutions extended from the technical means and scope of the utility model should also fall within the scope of the patent application of the utility model.
