[0022] Before the present invention is described in detail, it should be noted that similar elements are denoted by the same reference numerals in the following description.

[0023] See also Figures 1 to 3 A first embodiment of the hinge 100 of the present invention comprises a base 1 and a rotating shaft 2. It should be noted that the number of the rotating shaft 2 can be more than two, and should not be limited to the first embodiment.

[0024] The base 1 has a first axial concave-convex structure 11 and a first radial concave-convex structure 12. The rotating shaft 2 is rotatably arranged on the base 1, and the rotating shaft 2 has a second axial concave-convex structure 21 and a second radial concave-convex structure 22, wherein the first axial concave-convex structure 11 and the second axial concave-convex structure 21 are correspondingly matched along the axial direction D1 of the rotating shaft 2, and the first radial concave-convex structure 12 and the second radial concave-convex structure 22 are correspondingly matched along the radial direction D2 of the rotating shaft 2 to generate a torsion force that prevents or forces the rotating shaft 2 to rotate relative to the base 1. It should be noted that the radial direction should include all directions perpendicular to the axial direction D1, but for the convenience of explanation, only one radial direction D2 is shown in this article when the first radial concave-convex structure 12 and the second radial concave-convex structure 22 are correspondingly matched.

[0025] In the first embodiment, the base 1 includes a base 13 and a radial torque member 15 disposed on the base 13. The radial torque member 15 has a fixed portion 151 disposed on the base 13 and an elastic arm 152 extending from the fixed portion 151 and formed with the first radial concave-convex structure 12. The elastic arm 152 can form a ring structure together with the fixed portion 151, but the present invention is not limited thereto. The fixed portion 151 is formed with a protrusion 151a, and the base 13 is formed with a clamping groove 131 for clamping the protrusion 151a, so that the fixed portion 151 of the radial torque member 15 is fixed to the base 13. Further, the radial torque member 15 can be made of a slightly elastic material, such as steel, but the present invention is not limited thereto. In addition, the first axial concave-convex structure 11 is formed on an axial torque member 14 disposed on the base 13 and adjacent to the second axial concave-convex structure 21 of the rotating shaft member 2 in the first embodiment. However, it should be noted that, in a modified embodiment, both the first radial concave-convex structure 12 and the first axial concave-convex structure 11 can be directly formed on the seat body 13 , and are not limited to the first embodiment.

[0026] The rotating shaft member 2 includes a shaft body 23 rotatably inserted into the base 1, a sliding block 24 slidably sleeved on the shaft body 23 along the axial direction D1 of the rotating shaft member 2 and formed with the second axial concave-convex structure 21 and the second radial concave-convex structure 22, a stopper block 25 disposed on the shaft body 23, and an elastic body 26 sandwiched and connected between the sliding block 24 and the stopper block 25 and used to push the sliding block 24 toward the first axial concave-convex structure 11. In the first embodiment, the elastic body 26 has a plurality of overlapping spring sheets 261, and a gasket 27 is further disposed between the elastic body 26 and the stopper block 25, but the gasket 27 may also be omitted in a variant embodiment, which is not limited thereto.

[0027] In detail, the sliding block 24 is generally in the shape of a disk (disk, ring, or ring) and has a first side surface 241 facing the first axial concave-convex structure 11 of the base 1, a second side surface 242 facing the elastic body 26 and opposite to the first side surface 241, and an outer annular surface 243 connected between the first side surface 241 and the second side surface 242. The second axial concave-convex structure 21 is formed on the first side surface 241, and the second radial concave-convex structure 22 is formed on the outer annular surface 243. In addition, it should be noted that, in a variant embodiment, the second axial concave-convex structure 21 and the second radial concave-convex structure 22 can also be integrally formed on the shaft body 23 of the rotating shaft 2, which is not limited to the first embodiment.

[0028] Specifically, when the second axial concave-convex structure 21 and the first axial concave-convex structure 11 are in contact with each other in a concave-convex matching manner, the sliding block 24 of the rotating shaft 2 will be relatively close to the base 1 and relatively far away from the stop block 25. At this time, the elastic body 26 sandwiched between the sliding block 24 and the stop block 25 is subjected to less pressure and stores less elastic potential energy, so that the rotating shaft 2 is in a relatively stable state and generates a torsion force that prevents the rotating shaft 2 from rotating so that the rotating shaft 2 is not easily rotated. In addition, when the second axial concave-convex structure 21 is in contact with the first axial concave-convex structure 11 due to the rotation of the sliding block 24 of the rotating shaft 2, When the concave-convex structures 11 change from a state of concave-convex abutment with each other to a state of non-concave-convex abutment with each other, the sliding block 24 of the rotating shaft 2 will be relatively far away from the base 1 and closer to the stop block 25. At this time, the elastomer 26 sandwiched between the sliding block 24 and the stop block 25 is subjected to greater pressure and stores greater elastic potential energy, which makes the rotating shaft 2 in a relatively unstable state and easily generates a torque forcing the rotating shaft 2 to rotate, so that the rotating shaft 2 can be easily rotated to the angle where the second axial concave-convex structure 21 and the first axial concave-convex structure 11 are in concave-convex abutment with each other.

[0029] In addition, in the first embodiment, the first radial concave-convex structure 12 has a radial convex portion 121, and the second radial concave-convex structure 22 has a radial concave portion 221 matched with the radial convex portion 121. When the radial concave portion 221 of the second radial concave-convex structure 22 abuts against the radial convex portion 121 of the first radial concave-convex structure 12 in a concave-convex matching manner, the rotating shaft 2 will be in a relatively stable state, and a torsional force that prevents the rotating shaft 2 from rotating will be generated so that the rotating shaft 2 is not easily rotated.

[0030] It should be noted that the base 1 and the rotating shaft 2 can be respectively provided with two bodies (not shown) of an electronic product (not shown). By the first axial concave-convex structure 11 and the second axial concave-convex structure 21 correspondingly matched along the axial direction D1 of the rotating shaft 2, and the first radial concave-convex structure 12 and the second radial concave-convex structure 22 correspondingly matched along the radial direction D2 of the rotating shaft 2, the variability of the torque that prevents or forces the rotating shaft 2 to rotate relative to the base 1 is increased, so that the hinge 100 can meet the design requirements of various electronic products. In addition, it can be understood that the structures of the first axial concave-convex structure 11, the second axial concave-convex structure 21, the first radial concave-convex structure 12 and the second radial concave-convex structure 22 can all be changed to correspond to the design requirements of various electronic products, and should not be limited to the structure shown in this first embodiment.

[0031] See also Figures 4 to 6 A second embodiment of the hinge 100 of the present invention is different from the first embodiment in that, in the second embodiment, the hinge 100 comprises two rotating shaft members 2 arranged in parallel at intervals, and the rotating shaft members 2 can be respectively provided for two bodies of the electronic product. The base 1 has two first axial concave-convex structures 11 respectively corresponding to the second axial concave-convex structures 21 of the rotating shaft member 2, and two first radial concave-convex structures 12 respectively corresponding to the second radial concave-convex structures 22 of the rotating shaft member 2. The seat body 13 of the base 1 has a plurality of seat body pieces 132 arranged side by side and penetrated by the shaft body 23 of the rotating shaft member 2, and the first axial concave-convex structure 11 is formed on the seat body piece 132 of the second axial concave-convex structure 21 on the sliding block 24 of the rotating shaft member 2. For example, each first axial concave-convex structure 11 has two axial recesses 111 respectively located on both sides of the shaft body 23 of the corresponding rotating shaft 2, and each second axial concave-convex structure 21 has two axial protrusions 211 matching the axial recesses 111, but this is not limited thereto.

[0032] In addition, in the second embodiment, the radial torque member 15 has a fixing portion 151 disposed on the seat body 13, and two elastic arms 152 extending from the fixing portion 151 and respectively formed with the first radial concave-convex structure 12. The base 1 also has a fixing column 16 disposed on the seat body sheet 132 adjacent to the sliding block 24 of the rotating shaft member 2, and the fixing column 16 has an accommodating groove 161 formed at one end facing the seat body 13 for accommodating the fixing portion 151 of the radial torque member 15. In addition, the radial torque member 15 in the second embodiment is formed by stacking two sheets 153, but is not limited thereto.

[0033] Furthermore, each second radial concave-convex structure 22 has two radial recesses 221 spaced apart from each other. The radial recesses 221 respectively match with the radial protrusions 121 of the corresponding first radial concave-convex structure 12 when the rotating shaft 2 rotates to different angles.

[0034] In summary, the hinge 100 of the present invention increases the variability of the torque that prevents or forces the rotating shaft 2 to rotate relative to the base 1 by correspondingly matching the first axial concave-convex structure 11 and the second axial concave-convex structure 21 along the axial direction D1 of the rotating shaft 2, and correspondingly matching the first radial concave-convex structure 12 and the second radial concave-convex structure 22 along the radial direction D2 of the rotating shaft 2, so that the hinge 100 can meet the design requirements of various electronic products.

[0035] The above are merely embodiments of the present invention and should not be used to limit the scope of the present invention. That is, any simple equivalent changes and modifications made according to the claims and description of the present invention still fall within the scope of the present invention.
