Description
Technical field
The present invention relates to a kind of turning gear, the turning gear specifically a kind of notebook computer or DV used.
Background technique
Notebook computer compact volume and convenience, popularity is more and more higher, along with the height of notebook function is integrated, inevitably particularly be designed with many interfaces for external devices in base rear on the notebook base whole body, so just require there is a maximum opening angle between notebook computer base and screen board, subtended angle is excessive easily causes interference to external equipment wiring.
Existing notebook computer rotation shaft is provided with positioning device to play and limits screen board subtended angle scope, its axle core coordinates with banking stop, method one: mill out two locating faces in axle core side, banking stop is provided with corresponding axis hole and is mated, and banking stop strikes out fan-shaped, the defect of this structure is, axle core and banking stop are difficult to assemble, or easily there is idle stroke, and banking stop strength deficiency, axle core location facing cut is to root simultaneously, and rotating component and axle core surface of contact non-fully disc, also easily occur idle stroke; Method two: axle core and banking stop unitary design, overcome the defect assembling and occur idle stroke, but the derivative problem made new advances, axle core easily produces burr when rushing fan-shaped, cause interfering with the gear point of rotating component producing false torsion, axle core is whole in stamping process fan-shapedly has the bad phenomenon come off, and axle core fan-shaped gear point easily ruptures under the higher situation of heat treatment hardness.
Summary of the invention
The object of this invention is to provide a kind of rotating shaft being applicable to 3C electronic product, overcome in prior art the defect easily occurring that idle stroke, assembling difficulty and banking stop intensity are low.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
Be applicable to the rotating shaft of 3C electronic product, comprise axillare, spring plank, axle core, banking stop and torsion zone components, banking stop is provided with axis hole and coordinates with axle core, spring plank is connected with the screen board of notebook computer, spring plank is provided with gear point, gear point is corresponding with the sector notch of banking stop, and the axis hole on axle core and banking stop does and coordinates rear welding.
Described banking stop is that half extruding or stamping-out are shaping, and its sector notch is corresponding with the gear point on spring plank.
After banking stop is shaping, the reverse side of banking stop is plane, or banking stop reverse side and the position corresponding with sector notch is convex.Object is the intensity strengthening banking stop.
Described axle core cuts out two locating faces at end milling, for being connected with torsion zone components, is circular with the cross section of spring plank contact segment.Can avoid occurring idle stroke phenomenon in spring plank and axle core rotary course.
Beneficial effect of the present invention is:
The present invention makes the assembling of axle core and banking stop simplify, and avoid the defect occurring idle stroke, banking stop is that half extruding or stamping-out mode are shaping, increase under the prerequisite ensureing gear point function and connect material space, the intensity of banking stop self is increased greatly, and banking stop and cross section, axle core joint are wholecircle, in the process rotated around axle core at spring plank, not easily produce idle stroke.
