Description
Technical field
The present invention relates to a kind of rotating shaft, especially a kind of rotating shaft that realizes automatic open function.
Background technique
In the market, there are many electronic products to use turning shaft structure, for example notebook computer.Common notebook computer rotation shaft generally all is designed to barrier structure, lid is opened the certain open angle of Shi Douyou, but when the user uses often because of the carelessness or opening action inertia excessive, and being opened, rotating shaft surpassed maximum angle, will cause the damage of product turning shaft structure, cause damage.And other uses the device of turning shaft structure all can have similar situation to produce.Therefore the invention provides a kind of rotating shaft that can open automatically, the convenient use avoided the drawback of prior art.
Summary of the invention
In order to reach above-mentioned technical purpose, the invention discloses a kind of automatic unlatching rotating shaft, comprise first location piece, second location piece, it is characterized in that:
Described first location piece, one end is provided with jacket casing, and second location piece, one end is provided with central shaft, and central shaft is arranged at described jacket casing inside, makes the cooperation that is connected with second location piece of first location piece;
The end that described sleeve is connected with central shaft is provided with that curved surface is recessed takes turns, be inserted on the central shaft with curved surface is recessed and take turns corresponding curved surface cam, the recessed wheel of curved surface is correspondingly provided with the arc curve surface rail, be symmetrically arranged with two positioning convex on the described curved surface cam, match with the arc of described arc curve surface rail;
Described arc curve surface rail comprises two first guide rails and second guide rail, is provided with at interval along the circumference symmetry.
Described curved surface cam is connected with second location piece by spring, and by the elastic force effect of spring, first location piece and second location piece are when relative movement, and the curved surface cam slides on the recessed curvilinear gudie way of taking turns of curved surface, and tight connecting.Cooperate by the recessed location of taking turns of described curved surface cam and described curved surface, realize automatic unlatching, the locating function of rotating shaft.
Further technological scheme also comprises:
The described first track radian is less than the radian of second guide rail.
The described first guide rail arc-shaped curved surface axial height is less than the axial height of the second guide rail arc-shaped curved surface.
Be respectively equipped with some through holes on the shaft shoulder of described first location piece, the second location piece outer end, be used for fixing location piece, do relative motion so that make between first location piece and second location piece by rotation.
On the jacket casing cross section, the positioning convex of curved surface cam can be revised by curve form each other from the distance (be rotating shaft open stroke) that the first guide rail cambered top end slides into the second guide rail bottom, is made as 120 degree, 130 degree etc. as the guide rail radian.
When first location piece and second location piece are done mutual rotation, positioning convex is along the movement in a curve of arc curve guide rail, utilize the elasticity and the pressure of spring assembly, positioning convex slides into the arc bottom automatically along the inclined-plane of guide rail, make the angle that automatic unlatching rotating shaft is opened to automatically to be needed, and stable position is to the relevant position.That the present invention has is simple in structure, be easy to manufacture, the convenient advantage of using.

Embodiment
In order to make technological scheme of the present invention and technical purpose be easier to understand, the present invention is done further introduction below in conjunction with drawings and the specific embodiments.
As shown in Figure 1, a kind of automatic unlatching rotating shaft, comprise the first location piece 1(fixed end), the second location piece 2(movable end), first location piece, 1 right-hand member is provided with jacket casing 3, second location piece, 2 left ends are provided with central shaft 10, central shaft 10 is arranged at described jacket casing 3 inside, makes the cooperation that is connected with second location piece 2 of first location piece 1; The end that casing 3 is connected with central shaft 10 is provided with that curved surface is recessed takes turns 4, be with on the central shaft 10 and the recessed 4 curved surface cams 5 that match and use of taking turns of curved surface, the recessed wheel of curved surface is correspondingly provided with the arc curve surface rail on 4, described arc curve surface rail comprises two first guide rails 6 and second guide rail 7, be provided with at interval along the circumference symmetry, curved surface cam 5 is symmetrically arranged with two positioning convex 12 along circumference, matches with described arc curve surface rail, as shown in Figure 2.
As shown in Figure 5, on the jacket casing cross section, be the center of circle with the sleeve center, the first guide rail radian is made as 60 degree, and the second guide rail radian is made as 120 degree.Along the axial direction of rotating shaft, establish the arc height R of first guide rail, 6 arc height H less than second guide rail 7.Positioning convex 12 can be revised by changing each other the shape of curved surface from the distance (being the rotating shaft opening travel) that first guide rail, 6 cambered top end slide into second guide rail, 7 bottoms, as radian or the height that changes guide rail.
As shown in Figure 2, positioning convex 12 at first is fixed on first guide rail 6, and when first location piece 1 and second location piece 2 were done mutual rotation, positioning convex 12 was along the arc curve guide rail movement, utilize the elasticity and the pressure of spring assembly 8, positioning convex 6 rotates 30 from first guide rail, 6 arc bottoms
oAfter, arrive 1 boundary's point (being cambered top end), as shown in Figure 3.Because the effect of plurality of ramps and spring force, positioning convex 12 is bound to the bottom of second guide rail 7 automatically along the inclined-plane, and stable being positioned on this position, makes automatic unlatching rotating shaft be bound to maximum angle automatically, as shown in Figure 4.
Described automatic unlatching rotating shaft is provided with some through holes 9 along first location piece 1, the outward extending shaft shoulder in second location piece, 2 outer ends, is used for location piece is fixed on the corresponding position of product, by operation it is done relative motion.
Below disclose the present invention with preferred embodiment, so it is not in order to restriction the present invention, and all employings are equal to replaces or technological scheme that the equivalent transformation mode is obtained, all drops within protection scope of the present invention.
