[specific embodiment]

Please refer to Fig. 1, Fig. 2 and Fig. 7, the utility model hinge arrangement is mounted between notebook computer lid 70 and the pedestal 80, comprises one first inverted impulse body 100 and one second inverted impulse body 200.This first inverted impulse body 100 makes these lid 70 relative these pedestals 80 make pitch rotation.This second inverted impulse body 200 makes these lid 70 relative these pedestals 80 make left rotation and right rotation.

This first inverted impulse body 100 comprises one first transfer part 11 and one second transfer part 13, and this first transfer part 11 is to be assembled in this lid 70.This first transfer part 11 this second transfer part 13 relatively pivots.

This second inverted impulse body 200 comprises that first ball 50 and that swivel base 40, that a holder 30, is installed in this holder 30 rotationally is installed between swivel base 40 and this holder 30 realizes the keeper 60 that these swivel base 40 relative these holder 30 rotary courses are located.

This holder 30 is mounted in this notebook computer pedestal 80, comprises that a body 31, is from these body 31 part excircles the stretch out outstanding boss 32 that forms and some fixed parts 33 that stretches out from these body 31 bottoms and form.A through hole 35 is run through in these body 31 central authorities, and its inwall forms the linear slideway 36 of double-paraboloid and a mounting groove 37 of a sealing, and this mounting groove 37 vertically is connected with this slideway 36.This slideway 36 is to be connected to form by two sections identical parabola slideways, and as shown in Figure 4, the crest of this slideway 36 is positioned at B point and D point, promptly is positioned at the front and back side of this holder 30, and relative with the rear end face of this boss 32; The trough of this slideway 36 is positioned at A point and C point, promptly is positioned at the left and right sides of this holder 30.The rear end face of this boss 32 in position offers one and connects the positioning screw hole 38 of this boss 32 to these body 31 inwalls.

This swivel base 40 comprises that one can embed the cylindric shaft 42 in the through hole 35 of this holder 30.These shaft 42 end faces platform 44 that stretches out, these platform 44 outer rims extend to form a barrel 41 downwards.These barrel 41 periphery extend to form a pair of linking arm 43.These shaft 42 diameters are slightly less than the diameter of the through hole 35 of this holder 30.The excircle of this shaft 42 is in position established a storage tank 45.These shaft 42 excircles are axially arranged with some being used for and locating slot 421 that keeper 60 cooperates along it equably.The inner diameter of this barrel 41 is greater than these shaft 42 diameters and form a clearance space (not label) thus.This linking arm 43 is assembled in second transfer part 13 of this first inverted impulse body 100 by some screws (not label).In addition, these swivel base 40 central authorities are provided with a cavity (not label) power supply gas and are connected to cable and pass through.

Please refer to Fig. 6, this keeper 60 comprises that one slightly becomes tubular to have externally threaded housing 61, to be installed in springs 62 and in this housing 61 and to be assembled in this housing 61 and to be compressed on second ball 63 on this spring 62.Housing 61 front ends of this keeper 60 are slightly tapered, and the groove angle angle of the locating slot 421 of its cone angle and this swivel base 40 is identical, and the arm of angle line of this locating slot 421 was that the contact point and the ball 63 of this ball 63 and locating slot 421 is tangent.

Please also refer to Fig. 5, during assembling, earlier 200 assemblings of second inverted impulse body are located at this pedestal 80, with this first ball 50 pack into this swivel base 40 mounting groove 45 and make its mounting groove 37 slip into the slideway 36 of holder 30 along this holder 30, at this moment, the shaft 42 of this swivel base 40 inserts in the through hole 35 of this holder 30, the solid positioning screw hole 38 of keeper 60 spiral shells that will assemble again at this holder 30, and this second ball 63 is fastened in the locating slot 421 of this swivel base 40, then that the rear end face of these holder 30 boss 33 is outside, by the fixed part on it 33 this holder 40 is fixed on this notebook computer pedestal 80.Again first pivot part 100 is assembled in this lid 70, its second transfer part 13 is installed in the linking arm 43 of this swivel base 40 by some screws.

Lid 70 relative pedestal 80 pitch rotation that realize this notebook computer are rotated in first transfer part 11 of this first inverted impulse body 100 relative to second transfer part 13; The swivel base 40 of this second inverted impulse body 200 rotates lid 70 relative these pedestal 80 left rotation and right rotation that realize this notebook computer relative to this holder 30.

In the left rotation and right rotation process, the operator is around the rotational notebook computer lid 70 of this swivel base 40, the ball 50 that is installed in this swivel base 40 is rolled along the slideway 36 of this holder 30, being parabola rule between the fore-and-aft distance of these lid 70 relative these pedestals 80 and the left and right sides swing angle degree changes, as shown in Figure 4, among this figure, Y-axis is represented the fore-and-aft distance of these lid 70 relative these pedestals 80, and X-axis is represented the angle of these lid 70 relative these pedestal 80 rotations.For example, this lid 70 changes counterclockwise gradually goes up this pedestal 80, and promptly this swivel base 40 goes to the D point from the C of holder 30 point and goes to the process that A is ordered again, and the fore-and-aft distance of these lid 70 bottoms and these pedestal 80 upper surfaces increases earlier gradually, and then by reducing.The process that this lid 70 turns clockwise is also identical.This hinge arrangement changes vertical relative distance of lid 70 and pedestal 80 in rotation, thereby avoids the upper surface of these lid 70 these pedestals 80 of bottom scratch.

In addition, in the left rotation and right rotation process, the spring 62 of the keeper 60 of this hinge arrangement is subjected to force compresses, this second ball 63 is by rolling out in the locating slot 421 and rolling on these swivel base 40 outer walls, after turning over certain angle, ball 63 is absorbed in the locating slot 421 on shaft 42 outer walls of swivel base 40 once more, thereby reaches the location in this position.Can add lubrication oil in the locating slot 421 of above-mentioned swivel base 40,, guarantee that rotary course carries out smoothly to reduce wear.

According to actual needs, the shaft 42 of this swivel base 40 can be provided with a pair of storage tank 45 along diametric(al), installs two balls 50 respectively.This slideway 36 also can be arranged on the shaft 42 of this swivel base 40, and this ball 50 is arranged on the inwall of this holder 30.This slideway 36 can be constituted by the slideway of the inwall of the shaft 42 that is separately positioned on this swivel base 40 and this holder 30, and this ball 50 is clamped in this slideway 36.Be appreciated that according to the actual conditions difference this slideway 36 can be designed to other form, as chute or the slide rail that is connected to form by two sections circular arcs.This ball 50 can be designed to the rolling element of other form, as is installed in the roller of these swivel base 40 bottoms, perhaps is designed to the slide block form, and this slideway 36 is provided with corresponding structure and cooperates with it.This slideway 36 can be designed to realize that with this rolling element 50 these swivel base 40 relative these holders 30 can change any structure of lid 70 and these pedestal 80 vertical relative distances when rotating.

Also can understand, this hinge arrangement also can be used on other electronic equipments such as PDA, mobile phone, e-dictionary.
