Description

Hinge arrangement

[technical field]

The utility model is the hinge arrangement that is used for notebook computer about a kind of, especially refers to a kind of wear-resisting and can regulate the hinge arrangement of clamping force.

[technical background]

Existing notebook computer articulates by hinge between LCD and the main frame, and display can close on the main frame when not using, and can launch from main frame when needs use.In addition, LCD can stop at the required any angle of user upon deployment.Therefore, the tighter fit system of the essential employing of hinge can reach practical requirement.

Existing hinge as shown in Figure 1, is that a pivot 93 is passed an axle sleeve 91, and a friction ring 92 is set between this pivot 93 and axle sleeve 91, when these pivot 93 relative these axle sleeves 91 relatively rotate, can produce friction.But the generation friction will cause wearing and tearing to each other in the process of relatively rotating, and after use a period of time, the pivot joint between display and the main frame can produce loosening phenomenon.In addition, for heavier notebook computer, friction might take place encircle 92 tensions and be difficult for open and close, and the bad problem in location takes place after expansion.

[summary of the invention]

It is a kind of wear-resisting and can regulate the hinge arrangement of clamping force that the purpose of this utility model is to provide.

The purpose of this utility model is achieved through the following technical solutions: a kind of hinge arrangement comprises a holder, a rotating shaft and two springs.This holder runs through a shoulder hole vertically, at macropore lateral communication one pod of this shoulder hole.The two ends of this rotating shaft are respectively equipped with a pivot part and a joint portion.This two springs rotation direction is opposite, and is provided with some salient points in inner peripheral surface, and a grafting bar is extended in the end of each spring, and the inner ring diameter of these springs is less than the pivot part external diameter of rotating shaft.Pack into the shoulder hole of this holder of the rotating shaft that is arranged with these springs side by side at pivot part, the grafting bar of these springs can be contained in this pod, and this holder is stretched out in this joint portion.

Owing to adopted technique scheme, the wear-resisting and advantage that can regulate clamping force of hinge arrangement tool of the present utility model.

[specific embodiment]

See also Fig. 2, Fig. 3 and Fig. 5, hinge arrangement of the present utility model comprises a holder 10, a rotating shaft 20 and two springs 30.This holder 10 connects with the corresponding construction of notebook computer main frame 50, and the corresponding construction of these rotating shaft 20 1 ends and notebook computer display 40 connects.The rotating shaft 20 that is arranged with these springs 30 is contained in this holder 10, and this rotating shaft 20 relatively rotates with this holder 10, and this display 40 is pivoted with respect to this main frame 50.

This holder 10 roughly becomes column, runs through a shoulder hole 11 vertically, and this shoulder hole 11 comprises one big 13 and one aperture 15.Form a shaft shoulder 12 between this macropore 13 and this aperture 15.These macropore 13 side direction are established a pod 14, and this pod 14 is connected with this macropore 13.These holder 10 outsides have been symmetrically formed two fins 16 vertically, are provided with some grooves 17 near these fins 16.These fins 16 and groove 17 can connect with the corresponding construction of this main frame 50.

This rotating shaft 20 is major axis bodies, is provided with a pivot part 22, a locating part 23, one protruding axial region 24 and a joint portion 26 successively.This pivot part 22 is arranged on an end of this rotating shaft 20.This locating part 23 is darted at this pivot part 22 adjacent sides, and in the present embodiment, this locating part 23 is annular retaining rings, and its outside dimension is less than macropore 13 internal diameters of this holder 10, greater than these aperture 15 internal diameters.This protruding axial region 24 is arranged on the adjacent side of this locating part 23, and can be contained in the aperture 15 of this holder 10.This joint portion 26 is located at the other end of this rotating shaft 20, and the surface of this joint portion 26 is provided with some splines that are parallel to each other vertically, is to be used for connecting with the corresponding construction of display 40.Other structure can be arranged in this joint portion 26, as spline or projection etc.This locating part 23 also can be arranged to pivot part 22 spacing macropore 13 other forms at this holder 10, as block, backing pin etc.

These springs 30 are the opposite helical springs of two rotation directions.Its inner ring diameter is less than the external diameter of the pivot part 22 of this rotating shaft 20, and these springs 30 are set in this pivot part 22 and can form than tight fit.The inner peripheral surface of each spring 30 is provided with some salient points 32, and in the pivot process, these salient points 32 produce friction with these pivot part 22 surfaces.The end of this each spring 30 all extends one can be contained in grafting bar 34 in the pod 14 of this holder 10.

During assembling, can be according to any mode shown in Fig. 4 A-D, earlier these springs 30 are set in opposite directions, dorsad or side by side the pivot part 22 of this rotating shaft 20, pack into the in the lump shoulder hole 11 of this holder 10 of rotating shaft 20 that again will this tight sleeve spring 30 is contained in this pod 14 the grafting bar 34 of spring 30.This locating part 23 is resisted against the shaft shoulder 12 of this holder 10, and this protruding axial region 24 passes and is housed in this aperture 15, and stretch out in this aperture 15 this joint portion 26.The fin 16 of this holder 10 and groove 17 can connect with the corresponding construction of this main frame 50, and the joint portion 26 of this rotating shaft 20 can connect with the corresponding construction of display 40.
