In said structure, bevel is cutd open by setting torsion piece A and torsion piece B and being formed in shaft core, by shaft core
Cut open the cooperation of bevel and closure cambered surface A and torsion cambered surface A on torsion piece A, it is possible to achieve special angle self-closing function and rotation
Turn torsion, by the cooperation for cuing open bevel and closure cambered surface B and two sections of torsion cambered surface B on torsion piece B in shaft core, Ke Yishi
While existing special angle self-closing function, there is provided two sections of different rotary torsions, to meet different application scenarios.Pass through
Torsion piece A realizes that the technical principle of self-closing and rotary torsion is：The c-type through hole with stroke is formed on torsion piece A
A, c-type through hole A can to shaft core carry out elastomeric overmold, that is, surround c-type through hole A cladding wall constitute one it is flexible
Claw, when it is sleeved in shaft core, can elastomeric overmold on shaft core lateral surface, in this way, due to coat power presence, shaft core turn
When dynamic, relative friction will be produced between the medial surface of shaft core and c-type through hole A, using the rotary torsion relatively rotated as shaft core；
Non- bevel part of cuing open in the angle that closes of needs, shaft core is fallen into closure cambered surface A just, during this, c-type through hole A
Diminish to the cladding power of shaft core, i.e., rotary torsion diminishes, it can be achieved that automatic closure.Needing the angle of work, cuing open in shaft core
Bevel and the non-boundary line cutd open between bevel are crawled toward torsion cambered surface A by closure cambered surface through climbing face, during this, A pairs of c-type through hole
The cladding power of shaft core becomes larger, i.e., rotary torsion becomes larger, it is necessary to which larger power just can be with rotating shaft core, so as to provide certain rotation
Turn torsion.Realize that the technical principle of three sections of rotary torsions is by torsion piece B：The C with stroke is formed on torsion piece B
Type through hole B, c-type through hole B can carry out elastomeric overmold to shaft core, that is, the cladding wall that surround c-type through hole B constitutes one and has
Elasticity claw, when it is sleeved in shaft core, can elastomeric overmold on shaft core lateral surface, in this way, due to coat power presence, axis
Core will produce relative friction, using the rotation relatively rotated as shaft core when rotating between the medial surface of shaft core and c-type through hole B
Torsion；In first segment rotary torsion, non-in shaft core cuts open bevel part and falls into just in closure cambered surface B, during this, C
Type through hole B is minimum to the cladding power of shaft core；In second segment rotary torsion, cuing open bevel and non-cut open between bevel in shaft core
Boundary line is crawled toward the torsion cambered surface B of first segment by closure cambered surface B through the first climbing face, and during this, c-type through hole B is to shaft core
Cladding power becomes larger, i.e., rotary torsion becomes larger, it is necessary to which larger power just can be with rotating shaft core, so as to produce second segment rotary torsion.
In the 3rd section of rotary torsion, cut open bevel and the non-boundary line cutd open between bevel in shaft core are passed through by the torsion cambered surface B of first segment
Second climbing face crawls toward the torsion cambered surface B of second segment, and during this, c-type through hole B becomes larger the cladding power of shaft core, i.e. rotation is turned round
Power becomes larger, it is necessary to which the power of bigger just can be with rotating shaft core, so as to produce the 3rd section of rotary torsion.Preferably, the torsion of torsion piece A
Two sections of torsion cambered surface B of power cambered surface A and torsion piece B are misaligned, in this way, during practical application, torsion piece A is sustainable to produce clamping
Power, and accommodate power in 345-360 degree and disappear, it is produced from closure effect；And torsion piece B realizes first, second section in 0-340 degree
Become torsion, realize the 3rd section of change torsion in 340-360, i.e. torsion transition at this time, is produced from closure effect, and real in folding
Existing chucking power.In this way, first segment rotary torsion can be applied to the rotary torsion of common angle, second segment rotary torsion is larger, can
Applied to touch control operation position, such as, when user operates the display screen of folding type electronic product upper cover with touch control manner,
Good support effect can be provided, reduce the shortcomings that display screen rocks, the 3rd section of rotary torsion moment diminishes, and can be applied to
Self-closing during folding.Three-stage of the present invention, which becomes torque structure, can replace cam concave wheel closing structure, there is provided three sections of rotations are turned round
While power, self-closing function can be realized in special angle.Using its twin shaft core shaft, provide different rotary torsion and
While realizing special angle self-closing function, since torsion piece A and torsion piece B are directly coated in shaft core, the diameter of axle can be set
That counts is smaller, therefore, it is possible to reduce shaft the space occupied, can preferably meet the slimming of the electronic equipments such as laptop
Growth requirement.
In said structure, rotary torsion depends not only on the elasticity bag between shaft core and single torsion piece A and torsion piece B
Cover power, additionally depend on the friction area between shaft core and multiple torsion piece A and torsion piece B, therefore, by adjust torsion piece A and
The thickness or quantity of torsion piece B can obtain the rotary torsion of needs.And since torsion piece is directly coated in shaft core, by
Cladding power realizes rotary torsion, and therefore, it is relative to cam and concave wheel, smaller that the diameter of axle of shaft core can design takes empty
Between it is smaller, can preferably meet the slimming growth requirement of the electronic equipments such as laptop.
In theory, two shaft cores, which may be designed to the identical diameter of axle, can also design the different diameters of axle, be designed to the identical diameter of axle
When, in order to meet that occupied space is smaller, the diameter of axle of corresponding two shaft cores of torsion piece can be reduced as far as possible toward small design with reaching
The purpose of product size, but if two shaft cores all design very thin, the clad type rotary torsion that torsion piece provides will be unable to
Meet the requirement of actual use, therefore, as a kind of preferred embodiment, it is preferred that a shaft core is by the torsion
The diameter of axle of power piece A and torsion piece B claddings is less than the diameter of axle that another shaft core is coated by the torsion piece A and torsion piece B, and
The shapes and sizes all same of the torsion piece A and torsion piece B, the torsion piece A and the torsion piece B are in one end
The small long disc-shaped in big one end.I.e. by the relatively thick of shaft core design, to meet clad type rotary torsion that torsion piece provides
Integral strength demand, and another shaft core is tried one's best design it is relatively thin, to meet the needs of reduction shaft occupied space.
The opening direction of the c-type through hole A of torsion piece A can be overlapping with the opening direction of the c-type through hole B of torsion B, also may be used
With not overlapping, it is preferred that referring to Fig. 6, the opening direction and the c-type through hole of the torsion piece B of the c-type through hole of the torsion piece A
Opening towards different, i.e. the opening of the c-type through hole A of torsion piece A towards and the opening direction of the c-type through hole B of torsion B do not weigh
It is folded, to provide preferably cladding stability.
The torsion cambered surface A of torsion piece A and two sections of torsion cambered surface B of torsion piece B can be designed to overlapping or not in the axial direction
It is overlapping.Preferably, do not weighed axially referring to two sections of torsion cambered surface B of Fig. 6, the torsion cambered surface A of torsion piece A and the torsion piece B
It is folded.
