Description
[technical field]
The utility model is about a kind of hinge arrangement, especially about a kind of hinge arrangement that is used for mobile phone, PDA portable electronic equipments such as (Personal Digital Assistant, personal digital assistants).
[background technology]
At present, the portable electronic equipment of being sold on the market as mobile phone, PDA etc., mostly is accordion structure, promptly comprises lid and body, adopts hinge that lid and body is rotatable hinged.
A kind of hinge arrangement that industry more often adopts is the stage clip cam-type, and promptly adopting cam and compression spring is primary clustering, reaches certain folding function of lid and body.The hinge leaf device (please refer to Fig. 1) that is disclosed for No. 98109390.6 as Chinese patent application is the hinge arrangement of this type.This hinge leaf device comprises axle 10, spring 20, sliding cam 30, cam member 40 and snap ring 50.One end of axle 10 is established flange 102, and column fixture block 104 is established in flange 102 outsides, and this fixture block 104 cooperates with the portable electronic equipment body, and the cross section of main shaft 106 is non-circular, and the cross section of shaft end 108 is circular.Sliding cam 30 is a hollow circular cylinder, and the cross sectional shape of its centre bore 302 is consistent with main shaft 106 cross sectional shapes, and sliding cam 30 1 ends are cam surface 304.Cam member 40 is a hollow circular cylinder, in establish cylindric medium pore 402, its external surface is provided with the groove 404 that cooperates with the portable electronic equipment lid, cam member 40 1 ends are established cam surface 406.Axle 10 passes spring 20, sliding cam 30 and cam member 40 in turn, snap ring 50 is arranged in an end of axle 10 again.Sliding cam 30 is sheathed on the main shaft 106, and cam member 40 is sheathed on the shaft end 108.The cam surface 304 of sliding cam 30 keeps in touch under the elastic force effect of spring 20 with the cam surface 406 of cam member 40.By this hinge leaf device, when portable electronic equipment is opened by closure state, open lid, lid drives cam member 40 and rotates relative to sliding cam 30, sliding cam 30 then slides along main shaft 106, to certain angle, stop the application of force, lid opens to special angle automatically under the cam surface 304,406 of cam member 40 and sliding cam 30 and spring 20 actings in conjunction.
Adopt above-mentioned hinge arrangement, only need lid is opened certain angle, lid can be inverted to the precalculated position under hinge effect.When closed during with unlatching the start principle identical, it is comparatively convenient to use.So, when applying to this kind hinge arrangement in the portable electronic equipment, the relative body of lid is a stable state at closure state and complete opening state only, any angle betwixt is all unstable, it is needed arbitrarily angled promptly can not to make its lid and body can stay in the user, thereby this kind hinge arrangement obviously can not satisfy user's demand.
[utility model content]
The purpose of this utility model is to provide a kind of relative body of lid of portable electronic equipment that makes to open hinge arrangement at any angle.
In order to realize the purpose of this utility model, the utility model provides a kind of hinge arrangement, and it comprises shell body, rotor, spring and bottom, and wherein rotor comprises rotation end, cylinder and boss, cylinder is rotating between end and the boss, and the bottom of boss is provided with at least one groove; Spring is placed on the cylinder of above-mentioned rotor, and its length is greater than the length of cylinder; Shell body is a hollow cylinder, an end opening, and the other end is semiclosed, and semiclosed end forms a circular socket holes, and the boss of above-mentioned rotor and cylinder all are placed in this shell body and its rotation end passes the outside that this circular socket holes is arranged at shell body; Bottom is arranged in the openend of shell body, and be provided with on it one can with the projection of the engagement of above-mentioned rotor.
Compare existing hinge arrangement, the utility model hinge arrangement is simple in structure, and is easy to assembly, and can adapt to the specific function requirement of portable electronic equipments such as mobile phone, PDA, make its lid relatively body open arbitrarily angled.

[specific embodiment]
The utility model hinge arrangement is used for mobile phone, PDA portable electronic equipments such as (Personal DigitalAssistant, personal digital assistants).
Please refer to Fig. 2 and shown in Figure 3, the preferred embodiment of the utility model hinge arrangement comprises shell body 6, rotor 7, spring 8 and bottom 9.
The internal diameter of spring 8 is greater than the external diameter of cylinder 72 and less than the diameter of boss 74, its length is a bit larger tham the length of cylinder 72.
The openend 61 of the shape of bottom 9 and size and shell body 6 coincide, and a projection 92 is set on its upper surface 90, and this projection 92 can mesh with groove 742.
Please shown in Figure 4 in conjunction with reference, during assembling, elder generation passes spring 8 with rotor 7 and rotor 7 is inserted in the shell body 6, with bottom 9 and shell body 6 fastenings and feasible projection 92 and groove 742 engagements, at last registration arm 62 is bent to prevent bottom 9 landing from shell body 6 then.After assembling finishes, rotating end 70 stretches out from the circular socket holes 60 of shell body 6, because the length that the length of spring 8 is a bit larger tham cylinder 72, therefore spring 8 end after assembling finishes is held in the semiclosed end 63 of shell body 6, and the other end is held in boss 74, is in confined state, the elastic force that it produced makes projection 92 and groove 742 mesh more compactly, so, whole hinge arrangement forms a complete structure, reaches modularization.
Please refer to Fig. 5 and Fig. 6, the portable electronic equipment (figure does not show) that is suitable for the utility model hinge arrangement comprises lid and body.Lid cooperates with the shell body 6 of hinge arrangement, and the body rotation end 70 outer with being exposed to shell body 6 cooperates.When the relative body of lid was closed, the utility model hinge arrangement was in state shown in Figure 5, at this moment, projection 92 and groove 742 engagements, hinge arrangement is in metastable state; In relative body opening procedure with the portable electronic equipment lid, body drives to rotate holds 70 to rotate, skid off this moment protruding 92 from groove 742, when projection 92 slides on the bottom 740, rotor 7 further compresses spring 8, the stiction that the elastic force that spring 8 is produced makes a plurality of salient points 744 be produced increases, therefore projection 72 can stay in the optional position of bottom 740 by this stiction, the utility model hinge arrangement is in state shown in Figure 6, be to be arbitrarily angled between lid and the body, after rotating end Rotate 180 degree, projection 92 meshes with groove 742 again, hinge arrangement returns to state shown in Figure 5, and this moment, lid and body were 180 degree, were in full open position.If to make lid and body again closure then lid is rotated to body, pass through the start process identical and get final product with opening procedure.
Be appreciated that the foregoing description only is the preferred embodiment of the utility model hinge arrangement, hinge arrangement of the present utility model also can be realized by alternate manner.For example, bottom 9 fixedly be not limited to registration arm 62 lock modes, also can adopt modes such as welding, bonding or screw be fixing; The radial groove 742 of two intersections can also be set on the bottom 9, make hinge arrangement increase a kind of stationary state, for example be provided with two and be the radial groove 742 (figure does not show) that 150 degree intersect, then when lid is opened 150 degree angles with respect to body, projection 92 and wherein groove 742 engagements, this angle is suitable in the mobile phone communication process very much, when lid is opened 180 degree angles with respect to body, and projection 92 and another groove 742 engagements.
