Before the present invention is described in detail, it should be noted that in the following description, like elements are represented by like reference numerals.

Referring to fig. 1 to 3, a first embodiment of the hinge 100 of the present invention includes a base 1 and a rotating shaft 2. It should be noted that the number of the rotating shaft members 2 may be two or more, and should not be limited to the first embodiment.

The pivot piece 2 rotationally wears to locate base 1, pivot piece 2 has a second axial concave-convex structure 21, and a radial concave-convex structure 22 of second, wherein, first axial concave-convex structure 11 with second axial concave-convex structure 21 is followed the axial direction D1 of pivot piece 2 corresponds the cooperation, first radial concave-convex structure 12 with second radial concave-convex structure 22 is followed the radial direction D2 of pivot piece 2 corresponds the cooperation, in order to produce and prevent or force pivot piece 2 for base 1 pivoted torsion. It should be noted that the radial direction shall include all directions perpendicular to the axial direction D1, but for convenience of description, only one of the radial directions D2 is shown here, which the first radial relief structure 12 and the second radial relief structure 22 follow in corresponding cooperation with each other.

In the first embodiment, the base 1 includes a base body 13 and a radial torsion member 15 disposed on the base body 13, the radial torsion member 15 has a fixing portion 151 disposed on the base body 13, and an elastic arm 152 extending from the fixing portion 151 and forming the first radial concave-convex structure 12, and the elastic arm 152 and the fixing portion 151 may form an annular structure, for example, but not limited thereto. The fixing 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 fixing portion 151 of the radial torsion member 15 is fixed to the base 13. Further, the torsion member 15 may be made of a slightly elastic material, such as steel, but not limited thereto. Further, the first axial concavo-convex structure 11 is formed on an axial torsion member 14 provided on the base body 13 and abutting against the second axial concavo-convex structure 21 of the rotary shaft member 2 in the present first embodiment. 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 the first embodiment is not limited thereto.

The rotating shaft 2 includes a shaft 23 rotatably passing through the base 1, a sliding block 24 slidably sleeved on the shaft 23 along an axial direction D1 of the rotating shaft 2 and formed with the second axial concave-convex structure 21 and the second radial concave-convex structure 22, a stop block 25 disposed on the shaft 23, and an elastic body 26 sandwiched and connected between the sliding block 24 and the stop block 25 and used for pushing the sliding block 24 toward the first axial concave-convex structure 11. In the first embodiment, the elastic body 26 has a plurality of spring pieces 261 stacked one on another, and a spacer 27 is further disposed between the elastic body 26 and the stop block 25, but the spacer 27 may be omitted in a modified embodiment, which is not limited thereto.

In detail, the sliding block 24 is substantially shaped like a disk (disc, 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 uneven structure 21 is formed on the first side surface 241, and the second radial uneven structure 22 is formed on the outer annular surface 243. In a modified embodiment, the second axial direction concave-convex structure 21 and the second radial direction concave-convex structure 22 may be integrally formed on the shaft body 23 of the rotating shaft member 2, and the present embodiment is not limited thereto.

Specifically, when the second axial concave-convex structure 21 and the first axial concave-convex structure 11 are in concave-convex fit with each other and abut against each other, the sliding block 24 of the rotating shaft member 2 is relatively closer to the base 1 and further away from the stop block 25, and at this time, the elastic body 26 sandwiched between the sliding block 24 and the stop block 25 is subjected to a smaller pressure and has a smaller stored elastic potential energy, so that the rotating shaft member 2 is in a relatively stable state, and a torque force for preventing the rotating shaft member 2 from rotating is generated so that the rotating shaft member 2 is not easy to rotate; in addition, when the second axial concave-convex structure 21 and the first axial concave-convex structure 11 are changed from the state of being in concave-convex matched abutting contact with each other to the state of being in non-concave-convex matched abutting contact with each other due to the rotation of the sliding block 24 of the rotating shaft member 2, the sliding block 24 of the rotating shaft member 2 is relatively far away from the base 1 and relatively close to the stop block 25, at this time, the pressure applied to the elastic body 26 sandwiched between the sliding block 24 and the stop block 25 is relatively large, and the stored elastic potential energy is also relatively large, so that the rotating shaft member 2 is located in a relatively unstable state, and a torsion force for forcing the rotating shaft member 2 to rotate is easily generated, so that the rotating shaft member 2 is easily rotated to an angle at which the second axial concave-convex structure 21 and the first axial concave-convex structure 11 are in concave-convex matched abutting contact with each other.

Further, in the present first embodiment, the first radial concavo-convex structure 12 has a radial convex portion 121, and the second radial concavo-convex structure 22 has a radial concave portion 221 that mates with the radial convex portion 121. When the radial concave portion 221 of the second radial concave-convex structure 22 and the radial convex portion 121 of the first radial concave-convex structure 12 are in concave-convex fit abutment with each other, the rotating shaft member 2 will be in a relatively stable state, and a torsion force for preventing the rotating shaft member 2 from rotating is generated so that the rotating shaft member 2 is not easily rotated.

It should be noted that the base 1 and the rotating shaft 2 can be respectively provided for two bodies (not shown) of an electronic product (not shown). Through 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 member 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 member 2, the variability of the torque force for preventing or forcing the rotating shaft member 2 to rotate relative to the base 1 is increased, so that the hinge 100 can meet the design requirements of various electronic products. It should be understood that the configurations of the first axial uneven structure 11, the second axial uneven structure 21, the first radial uneven structure 12, and the second radial uneven structure 22 may be changed according to the design requirements of various electronic products, and the configuration shown in the first embodiment should not be limited.

Referring to fig. 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 includes two rotating shaft members 2 juxtaposed at an interval, and the rotating shaft members 2 can be respectively provided for two bodies of the electronic product. The base 1 has two of the first axial concavo-convex structures 11 corresponding to the second axial concavo-convex structures 21 of the rotary shaft member 2, respectively, and two of the first radial concavo-convex structures 12 corresponding to the second radial concavo-convex structures 22 of the rotary shaft member 2, respectively. The seat body 13 of the base 1 has a plurality of seat body pieces 132 which are arranged side by side and penetrated by the shaft body 23 of the rotating shaft member 2, and the first axial concavo-convex structure 11 is formed on the seat body piece 132 adjacent to the second axial concavo-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 concave parts 111 respectively located at two sides of the shaft body 23 of the corresponding rotating shaft member 2, and each second axial concave-convex structure 21 has two axial convex parts 211 matching with the axial concave parts 111, but not limited thereto.

In addition, in the second embodiment, the radial torsion element 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 forming the first radial concave-convex structure 12. The base 1 further has a fixing column 16 disposed on the seat piece 132 adjacent to the sliding block 24 of the rotating shaft member 2, and an accommodating groove 161 for accommodating the fixing portion 151 of the radial torsion member 15 is formed at an end of the fixing column 16 facing the seat body 13. In addition, the radial torsion member 15 is formed by overlapping two sheets 153 in the second embodiment, but not limited thereto.

Furthermore, each second radial concave-convex structure 22 has two radial concave portions 221 spaced from each other, and the radial concave portions 221 are concave-convex matched with the radial convex portions 121 of the corresponding first radial concave-convex structure 12 when the rotating shaft member 2 rotates to different angles.

To sum up, the utility model discloses hinge 100 is through following the axial direction D1 of pivot piece 2 corresponds the complex first axial concave-convex structure 11 with second axial concave-convex structure 21, and follow the radial direction D2 of pivot piece 2 corresponds the complex first radial concave-convex structure 12 with the radial concave-convex structure 22 of second increases and prevents or forces pivot piece 2 for the variability of base 1 pivoted torsion, so that hinge 100 can accord with the design demand of various types of electronic product.
