Embodiment
Please refer to Fig. 1-shown in Figure 3, the turning gear (not label) that the utility model is used for notebook computer comprises that spacing regulating ring 2, spring 3, spring regulate steel disc 4, main shaft 5 and support 8.
Described support 8 comprises tabular brace 88, is located at brace 88 one sides and slightly becomes the connection platform 82 of longitudinal, bends respectively from two ends of brace 88 and extend first, second catch 84,86 that forms.Described connection platform 82 is provided with some threaded holes 822 with same intervals, described first catch 84 roughly pars intermedia is provided with first pilot hole 842, in edge first fixed orifice 846 is set near first pilot hole 842, the edge of first catch 84 is provided with a breach 844, on described second catch 86 second pilot hole 862 is set.The selection of above-mentioned support 8 can be adopted steel or alloy material etc. according to actual needs.
Described main shaft 5 can be by first, second pilot hole 842,862 location of support 8, main shaft 5 is generally made by steel, comprise auxiliary section 52 and reverse respectively first, second free end 54,56 that extends in 52 two ends from the auxiliary section, the cross section of described auxiliary section 52 is circular, and the cross section of described first, second free end 54,56 is a flattened round.
Described spring is regulated steel disc 4 by the steel processing and fabricating, comprises cooperation main body 42, cooperates main body to the connecting portion 44 of 42 times bending extensions and the fixed part 46 that extends from connecting portion 44 other ends certainly.Be provided with on the described cooperation main part 42 second through hole 422 and with second stiff end, 36 corresponding second fixed orifices 424 of spring 3, and the diameter of described second fixed orifice 424 can with the equal diameters of second stiff end 36 of spring 3.In the illustrated embodiment, second through hole 422 is roughly the shape of flat circle, near the centre position the 3rd fixed orifice 462 is set on the described fixed part 46.
Described spacing regulating ring 2 comprises spacing block set 24 that the edge bending of regulating ring main body 22, self-regulation ring main body 22 extends to form and first through hole 26 that is located at regulating ring main body 22 centre positions, described first through hole 26 be shaped as flattened round.
Described turning gear also comprises holding screw 1,6 that can main shaft 5 relative supports 8 are fixing rotationally and the flexible adjustment steel disc 7,9 that can be set in first, second free end 54,56 of main shaft 5.Be provided with screw thread (not shown) in the hole of described holding screw 1,6 and on first, second free end 54,56 of main shaft 5.Described holding screw 1,6 and flexible adjustment steel disc 7,9 all can be to adopt traditional material and processing mode to be made.
Please refer to Fig. 2, shown in Figure 3, during combination, the element on the left side begins to describe from Fig. 2, contiguous first free ends 54 places, the auxiliary section 52 of main shaft 5 are inserted in first pilot hole 842 of first catch 84 of support 8, first through hole 26 of spacing regulating ring 2 is enclosed within on first free end 54 subsequently and spacing block set 24 is placed in the breach 844 of support 8, two flexible adjustment steel discs 9 are placed on the left side of spacing regulating ring 2, subsequently holding screw 1 are placed on the left side of flexible adjustment steel disc 9 and are tightened in first free end 54 of main shaft 5.
The spring main part 32 of spring 3 is set on the auxiliary section 52 of main shaft 5, and first stiff end 34 of spring 3 passes first fixed orifice 846 of first catch 84, first stiff end, 34 bendings afterwards fasten first catch of support 8, thereby realize the fixing of spring 3 and support 8.Spring is regulated steel disc 4 and is arranged on second free end 56 of main shaft 5 by second through hole 422, and second stiff end 36 of described spring 3 passes to turn back behind second fixed orifice 424 and fastens spring and regulate steel disc 4.862, two flexible adjustment steel discs 7 of second fixed orifice that second free end 56 of main shaft 5 inserts support 8 are set in second stiff end 56 of main shaft 5 subsequently, and holding screw 6 is placed on the right side of flexible adjustment steel disc 7 and is tightened on second free end 56 of main shaft 5.
During use, fastener (as screw) is fixed to support 8 on the base of notebook computer (not shown) by the threaded hole 822 that support 8 connects on the platforms 82, and the fixed part 46 of simultaneously spring being regulated steel disc 4 is fixed to the rotating part of notebook computer upper cover display screen by the fastener (as screw or bolt etc.) that passes the 3rd fixed orifice 462 and rotates with the rotating part of display screen.And, according to actual needs, can adjust the distance between first, second catch 84,86 of holding screw 1,6 and support 8, flexible adjustment steel disc 7,9 stressed elastic deformations, thus change the damping force that main shaft 5 produces when rotating notebook computer upper cover.
On notebook computer, cover when closing, the elastic deformation maximum of spring 3, the spacing block set 24 of spacing regulating ring 2 is in breach 844 bottom, when starting loam cake, the torsion that spring 3 elastic deformations produce is subdued mutually with the damping force of main shaft 5, thereby reduce the user and start the needed power of loam cake, start the increase of angle along with loam cake, the spacing block set 24 of spacing regulating ring 2 rotates synchronously around the shaft device and the main shaft 5 of loam cake, thereby the elastic deformation of spring 3 reduces the torsion of elastic deformation generation gradually also to be reduced gradually, the damping force of main shaft 5 also reduces gradually, the power that the user continues to lift loam cake does not have too big change, the protrusion wall that snaps into above-mentioned breach 844 when the spacing block set 24 of spacing regulating ring 2 (is seen Fig. 3, label not) time, spacing regulating ring 2 can not be rotated further, thus also rotary upper cover again of user, the maximum anglec of rotation that this has just guaranteed loam cake prevents that loam cake is owing to the overweight thing that causes turning over behind the notebook computer takes place.Certainly the user can stop the characteristics angle of loam cake in maximum rotation angle range according to self needs.
Certainly, the shape of above-mentioned connecting portion 44 is according to notebook computer volume inside size, if the notebook computer volume inside is enough big, connecting portion 44 also can be straight, or other forms of bending shape.
The cross sectional shape of first, second free end 54,56 of the shape of described first, second through hole 26,422 and main shaft 5 is not limited to flattened round, so long as the shapes that match that can make spacing regulating ring 2, spring regulate steel disc 4 and main shaft 5 synchronous rotations get final product.Perhaps, in first through hole 26 of spacing regulating ring 2, spring regulates in second through hole 422 of steel disc 4 and on first, second free end 54,56 of main shaft 5 suitable screw thread all is set, to realize three's synchronous rotation.
Flexible adjustment steel disc the 7, the 9th is used for the damping force of regulating main shaft 5 better when holding screw 1,6 is tightened or unclamped, therefore also can be according to actual needs, first, second free end 54,56 at main shaft 5 is not provided with flexible adjustment steel disc 7,9, only be provided with respectively a flexible adjustment steel disc 7,9, only on one of first, second free end 54,56, be provided with one or more etc.
Therefore, the present invention has only adopted low relatively infrastructure cost, just can realize that the user starts the notebook computer that needs big folding power with less power, and the display screen of notebook computer is stopped at special angle, make user's body when using notebook computer more comfortable, simultaneously can guarantee that notebook computer does not turn over the damage that causes element after the meeting, thereby further set up the practicality high-tech image of notebook computer.
The above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection domain of the utility model claim.
