Technical Field

The present invention relates to a hinge, and more particularly, to a hinge capable of generating a positioning torque.

Background

In recent years, hinges are widely used in various electronic products, and most of the hinges generally have a solid rotation axis, however, the hinge with the solid rotation axis is usually larger in size and difficult to be applied to light and thin electronic products. In addition, the space required for the torque module with gears in the hinge to provide positioning torque also makes the hinge difficult to reduce in size, and further, there is a problem of idle stroke between the gears in the torque module.

In some embodiments, the hinge of the present invention includes a base, a first sliding member, a plurality of first passive friction plates, and a plurality of first active friction plates. The base has a first track structure extending about a first axis of rotation. The first sliding part is provided with a first sliding structure which is slidably arranged on the first track structure, and the first sliding part can slide between a first position and a second position around the first rotating shaft relative to the base through the cooperation of the first track structure and the first sliding structure. The first driven friction plates are arranged on the base at intervals along the front-back direction parallel to the first rotating shaft. The first driving friction plates are arranged on the first sliding part at intervals along the front-back direction and are in overlapped contact with the first driven friction plates.

In some embodiments, the base has a first installation groove, the first sliding member is disposed in the first installation groove, the first rail structure has two first concave rails formed in the first installation groove along the front-back direction and located on both sides of the first sliding member along the front-back direction, and the first sliding structure has two first convex strips formed in the first sliding member along the front-back direction and slidably disposed in the first concave rails.

In some embodiments, the first passive friction plate has a bending portion bending toward the front-back direction and abutting against the adjacent first active friction plate.

In some embodiments, the first active friction plate has a bending portion bending toward the front-back direction and abutting against the adjacent first passive friction plate.

In some aspects, when the first sliding member is in the first position, the base, the first sliding member, the first passive friction plate and the first active friction plate are spaced apart from the first rotation axis by a distance, and the first rotation axis is located above the hinge.

In some embodiments, the base has a second rail structure extending around a second rotation axis, the second rotation axis being parallel to the front-rear direction, the hinge further comprises a second sliding member having a second sliding structure slidably disposed on the second rail structure, the second sliding member being slidable between a first position and a second position around the second rotation axis relative to the base by cooperation of the second rail structure and the second sliding structure, a plurality of second passive friction plates disposed on the base in a spaced-apart manner in parallel to the front-rear direction, and a plurality of second active friction plates disposed on the second sliding member in a spaced-apart manner in the front-rear direction and in overlapping contact with each other, when the first sliding member slides from the first position to the second position and the second sliding member slides from the second sliding member, the hinge further comprises a second sliding member, a plurality of second passive friction plates, and a plurality of second active friction plates When the first position slides to the second position, the first sliding part and the second sliding part oppositely move relative to the base and are changed from an unfolding shape to a folding shape relative to the base.

In some implementations, the first and second axes of rotation are spaced apart from each other along a left-right direction.

In addition, the first sliding structure 21 further has two first protrusions 212 respectively corresponding to the first protruding strips 211, and each of the first protrusions 212 and the corresponding first protruding strip 211 define one of the two first protruding walls 172 of the corresponding first concave rail 171 together for enhancing the stability of the first sliding member 2 during sliding. It should be noted that in an alternative embodiment, the first track structure 17 may be in the form of a land track instead of a groove track, and the first sliding structure 21 has a recess for matching with the land track. In addition, the first sliding member 2 further has a first setting portion 22 for assembling and connecting with a machine body (not shown), and the machine body can pivot relative to the machine body through the cooperation between the base 1 and the first sliding member 2.

The first sliding member 2 can slide between a first position and a second position around the first rotation axis a1 relative to the base 1 by the cooperation of the first track structure 17 and the first sliding structure 21, so that the hinge 100 can omit a physical rotation axis to reduce the volume.

Referring to fig. 1 to 3 and 6, the first passive friction plates 3 are disposed on the base 1 at intervals along the front-rear direction D1. In this embodiment, the first passive friction plate 3 is partially accommodated in the first accommodating part 13 of the base 1 and extends into the first setting groove 16. The first receiving member 13 has a positioning hole 131, each first passive friction plate 3 has a positioning protrusion 31 penetrating through the positioning hole 131 correspondingly, and fixing

holes

132 and 32 for fixing members (not shown) to be inserted are formed in the front-back direction D1 of the first receiving member 13 and the first passive friction plate 3, respectively, so that the first passive friction plate 3 is fixed to the first receiving member 13 of the base 1.

The first active friction plates 4 are arranged on the first sliding member 2 at intervals along the front-back direction D1 and contact with the first passive friction plates 3 in an overlapping manner, and a positioning torsion force for preventing relative movement between the first sliding member 2 and the base 1 is generated by a friction force between the first active friction plates 4 and the first passive friction plates 3. In the present embodiment, the first driving friction plate 4 is accommodated in the first sliding member 2 and located in the first arrangement groove 16 so as to be in overlapping contact with the first driven friction plate 3.

In addition, each of the first passive friction plates 3 further has a sliding slot hole 33 formed therein for one of the fixing members disposed on the first sliding member 2 and the first active friction plate 4 and disposed in the fixing hole 42 'with a smaller aperture to pass through, when the first sliding member 2 slides relative to the base 1, the one of the fixing members can slide along the sliding slot hole 33, so as to limit the sliding path of the first active friction plate 4 relative to the first passive friction plate 3, and further, the one of the fixing members disposed in the fixing hole 42' mainly functions to limit the relative movement relationship between the first active friction plate 4 and the first passive friction plate 3. The first passive friction plate 3 and the first active friction plate 4 may be, for example, metal plates manufactured by a precision stamping process, but not limited thereto.

The hinge 100 can omit a torque module with a gear under the condition of providing a positioning torque by the first passive friction plate 3 and the first active friction plate 4 respectively arranged on the base 1 and the first sliding member 2 and in overlapping contact with each other, so that the volume is relatively reduced, and the idle stroke problem of the gear is avoided.

In the present embodiment, the first passive friction plate 3 further has a bending portion 34 bending toward the front-back direction D1 and abutting against the adjacent first active friction plate 4, and the first active friction plate 4 further has a bending portion 43 bending toward the front-back direction D1 and abutting against the adjacent first passive friction plate 3. The bending part 34 of the first passive friction plate 3 and the bending part 43 of the first active friction plate 4 can increase the friction force between the first passive friction plate 3 and the first active friction plate 4 to further increase the positioning torque between the first sliding member 2 and the base 1, and in addition, the positioning torque between the first sliding member 2 and the base 1 can also be adjusted by adjusting the bending angle between the bending part 34 of the first passive friction plate 3 and the bending part 43 of the first active friction plate 4.

Referring to fig. 1 to 3 and fig. 6, in the present embodiment, the second fixing element 12, the second accommodating element 14 and the connecting element 15 of the base 1 jointly define a second setting groove 18, and the second sliding element 5 is disposed in the second setting groove 18 and arranged with the second accommodating element 14 along the left-right direction D2. Further, since the second installation groove 18 and the first installation groove 16 are offset from each other in the front-rear direction D1, the second slider 5 and the first slider 2 are also offset from each other in the front-rear direction D1, and thereby the space inside the hinge 100 can be utilized more efficiently, and the size of the hinge 100 in the left-right direction D2 can be reduced.

The base 1 has a second track structure 19 extending around a second rotation axis a2 parallel to the front-back direction D1, the second slider 5 has a second sliding structure 51 extending around the second rotation axis a2 and slidably disposed on the second track structure 19, and the second slider 5 can slide between a first position and a second position around the second rotation axis a2 relative to the base 1 by the cooperation of the second track structure 19 and the second sliding structure 51. In the present embodiment, the first rotation axis a1 and the second rotation axis a2 are spaced apart from each other along the left-right direction D2, but in a modified embodiment, the first rotation axis a1 and the second rotation axis a2 may not be spaced apart from each other and overlap each other, and the present embodiment is not limited thereto. In detail, the second track structure 19 has two second concave tracks 191 formed in the second arrangement groove 18 along the front-back direction D1 and located on two sides of the second sliding member 5 along the front-back direction D1, and in detail, the second concave tracks 191 are formed in the second fixing member 12 and the connecting member 15 respectively in the present embodiment; the second sliding structure 51 has two second protruding strips 511 formed on the second slider 5 along the front-back direction D1 and slidably disposed on the second groove rail 191. In addition, the second sliding structure 51 further has two second protrusions 512 respectively corresponding to the second protruding strips 511, and each of the second protrusions 512 and the corresponding second protruding strip 511 together define one of the two second protruding walls 192 of the corresponding second concave track 191, so as to enhance the stability of the second sliding member 5 during sliding. It should be noted that in an alternative embodiment, the second track structure 19 may be in the form of a land track instead of a groove track, and the second sliding structure 51 may have a recess for matching with the land track. In addition, the second sliding member 5 further has a second setting portion 52 for assembling and connecting with another machine body (not shown), and the other machine body can pivot relative to the base body through the cooperation between the base 1 and the second sliding member 5.

When the first sliding member 2 slides from the first position to the second position and the second sliding member 5 slides from the first position to the second position, the first sliding member 2 and the second sliding member 5 move oppositely relative to the base 1 and change from an unfolded state to a folded state relative to the base 1, in this embodiment, the first sliding member 2 and the second sliding member 5 rotate by about 90-95 degrees in the process, but not limited thereto. Therefore, the machine body arranged on the first sliding part 2 and the second sliding part 5 can be unfolded and folded relative to the base body arranged on the base 1.

The second passive friction plates 6 are provided on the base 1 so as to be arranged at intervals in the front-rear direction D1. In this embodiment, the second passive friction plate 6 is partially accommodated in the second accommodating part 14 of the base 1 and extends into the second setting groove 18. The second receiving member 14 has a positioning hole 141, each second passive friction plate 6 has a positioning protrusion 61 penetrating through the positioning hole 141 correspondingly, and fixing

holes

142, 62 for fixing members (not shown) to be inserted are formed along the front-back direction D1 respectively in the second receiving member 14 and the second passive friction plate 6, so that the second passive friction plate 6 is fixed to the second receiving member 14 of the base 1.

The second driving friction plates 7 are disposed on the second sliding member 5 at intervals along the front-back direction D1 and contact with the second driven friction plates 6 in an overlapping manner, and a positioning torsion force for preventing relative movement between the second sliding member 5 and the base 1 is generated by a friction force between the second driving friction plates 7 and the second driven friction plates 6. In this embodiment, the second driving friction plate 7 is received in the second sliding member 5 and is located in the second setting groove 18 so as to be overlapped with and in contact with the second driven friction plate 6. The second sliding member 5 has a plurality of positioning holes 53, each second active friction plate 7 has a plurality of positioning protrusions 71 that protrude from the positioning holes 53, and fixing holes 54 and 72 (72') through which fixing members (not shown) are inserted are formed in the front-rear direction D1 of the second sliding member 5 and the second active friction plate 7, respectively, so that the second active friction plate 7 is fixed to the second sliding member 5. In addition, each of the second passive friction plates 6 further has a sliding slot 63 formed therein for one of the fixing members disposed on the second sliding member 5 and the second active friction plate 7 and disposed in the fixing hole 72 'with a smaller aperture to pass through, when the second sliding member 5 slides relative to the base 1, the one of the fixing members can slide along the sliding slot 63, so as to limit the sliding path of the second active friction plate 7 relative to the second passive friction plate 6, and further, the one of the fixing members disposed in the fixing hole 72' mainly functions to limit the relative movement relationship between the second active friction plate 7 and the second passive friction plate 6. The second passive friction plate 6 and the second active friction plate 7 may be, for example, metal plates manufactured by a precision stamping process, but not limited thereto.

In the present embodiment, the second passive friction plate 6 further has a bent portion 64 bent toward the front-rear direction D1 for abutting against the adjacent second active friction plate 7, and the second active friction plate 7 further has a bent portion 73 bent toward the front-rear direction D1 for abutting against the adjacent second passive friction plate 6. The friction force between the second passive friction plate 6 and the second active friction plate 7 can be increased by the bending portion 64 of the second passive friction plate 6 and the bending portion 73 of the second active friction plate 7, so as to further increase the positioning torsion force between the second sliding member 5 and the base 1, and in addition, the positioning torsion force between the second sliding member 5 and the base 1 can also be adjusted by adjusting the bending angle between the bending portion 64 of the second passive friction plate 6 and the bending portion 73 of the second active friction plate 7.

In addition, when the first slider 2 and the second slider 5 are in the first position, the base 1, the first slider 2, the first passive friction plate 3, and the first active friction plate 4 are spaced apart from the first rotation axis a1, the base 1, the second slider 5, the second passive friction plate 6, and the second active friction plate 7 are spaced apart from the second rotation axis a2, and the first rotation axis a1 and the second rotation axis a2 are located above the hinge 100, in other words, the first rotation axis a1 and the second rotation axis a2 are located away from the hinge 100 itself. It should be noted that, in an alternative embodiment, the first rotation axis a1 and the second rotation axis a2 may be located inside the hinge 100, if necessary, and are not limited thereto. Therefore, when the first sliding member 2 and the second sliding member 5 are located at the second position and the body is folded relative to the base, the body and the base can define a larger screen accommodating space (not shown) together, so that the body and the base can be suitable for a flexible screen (not shown) with a larger space required by the bending position, in detail, the flexible screen is disposed above the body, for example. In addition, since the first rotating shaft a1 and the second rotating shaft a2 are spaced from each other in the left-right direction D2, the distance between the bodies of the first sliding part 2 and the second sliding part 5 can be increased, so as to further increase the screen accommodating space defined by the bodies and the housing.

In summary, the hinge 100 of the present invention enables the first sliding member 2 (the second sliding member 5) to slide between a first position and a second position around the first rotation axis a1 (the second rotation axis a2) relative to the base 1 by the cooperation of the first track structure 17 (the second track structure 19) and the first sliding structure 21 (the second sliding structure 51), so that the hinge 100 can omit a physical rotation axis to reduce the volume. In addition, the hinge 100 can omit a torsion module with a gear under the condition of providing positioning torsion by the first passive friction plate 3 (second passive friction plate 6) and the first active friction plate 4 (second active friction plate 7) which are respectively arranged on the base 1 and the first sliding member 2 (second sliding member 5) and are in overlapped contact with each other, so that the volume is relatively reduced, and the problem of idle stroke of the gear is avoided.

The above description is only an example of the present invention, and the scope of the present invention should not be limited thereby, and the invention is still within the scope of the present invention by simple equivalent changes and modifications made according to the claims and the contents of the specification.
