[56] on the other hand, Fig. 3 is the demonstration stationary cam that hinge means of the present invention adopted and the front elevation of rotating cam.Fig. 4 is the skeleton view of Fig. 3.Fig. 5 is the skeleton view at another visual angle of Fig. 4.
[57] in addition, Fig. 6 has shown the horizontal curvature figure of the stationary cam among Fig. 3.Fig. 7 has shown the horizontal curvature figure of the rotating cam among Fig. 3.Fig. 8 has shown the horizontal curvature figure of the restraint drive cam of the rotating cam among Fig. 3.
[58] as shown in the figure, on the cam face of stationary cam 50, form the first cam groove 52a and the second cam groove 52b, and extend to certain angle, face with each other with respect to through hole 51.Between the first cam groove 52a and the second cam groove 52b, form the first cam face 53a and the second cam face 53b, form the acclivitous first inclined-plane 54a, the second inclined-plane 54b, the 3rd inclined-plane 54c and the 4th inclined-plane 54d therebetween.
That is to say that [59] the first cam groove 52a extends out from the side of the first cam face 53a, form the first inclined-plane 54a therebetween.The second cam face 53b extends out from the side of the first cam groove 52a, forms the second inclined-plane 54b therebetween.The second cam groove 52b extends out from the side of the second cam face 53b, forms the 3rd inclined-plane 54c therebetween.Equally, the first cam face 53a along the circumferential direction extends out from the side of the second cam groove 52b, forms the 4th inclined-plane 54d therebetween.
[60] the first cam groove 52a and the second cam groove 52b, and the first cam face 53a and the second cam face 53b are each other at grade, the plane that extends to their excircles from the excircle of through hole 51 has constituted identical plane respectively.
[61] and, certain part (near the center of first cam face) from the first inclined-plane 54a that forms border between the first cam face 53a and the first cam groove 52a to the first cam face 53a has formed block 55, and this block projects upwards from the first cam face 53a.
[62] width of block 55 is that the circumference of through hole 51 of stationary cam 50 is to the intermediate point between through hole circumference and the stationary cam circumference.
[63] height of block 55 and width correspond respectively to the height and the width on the restraint drive cam surface of rotating cam, will be described below.
[64] on the other hand, formed the first cam face 62a and the second cam face 62b at the cam face of rotating cam 60, they correspond respectively to the first cam groove 52a and the second cam groove 52b of stationary cam 50.In addition, also formed the first cam groove 63a and the second cam groove 63b, they correspond respectively to the first cam face 53a and the second cam face 53b of stationary cam 50.
That is to say that [65] the first cam face 62a of rotating cam 60, the second cam face 62b, the first cam groove 63a and the second cam groove 63b correspond respectively to the first cam groove 52a, the second cam groove 52b, the first cam face 53a and the second cam face 53b of stationary cam 50.
[66] similar with stationary cam 50, in rotating cam 60, the first cam face 62a extends out from the side of the first cam groove 63a, forms the first inclined-plane 64a therebetween.The second cam groove 63b extends out from the side of the first cam face 62a, forms the second inclined-plane 64b therebetween.The second cam face 62b extends out from the side of the second cam groove 63b, forms the 3rd inclined-plane 64c therebetween.Equally, the first cam groove 63a along the circumferential direction extends out from the side of the second cam face 62b, forms the 4th inclined-plane 64d therebetween.
[67] therefore, the first inclined-plane 64a of rotating cam 60, the second inclined-plane 64b, the 3rd inclined-plane 64c and the 4th inclined-plane 64d correspond respectively to the first inclined-plane 54a, the second inclined-plane 54b, the 3rd inclined-plane 54c and the 4th inclined-plane 54d of stationary cam 50.
[68] on the other hand, in rotating cam 60, the width of the second cam groove 63b extends to the circumference of dihedral groove 61 at grade from circumference wherein.
[69] still, the part from the first inclined-plane 64a to the first cam groove 63a, the second cam face 62b and the second cam groove 63b provide the width that extends to the specific range of dihedral groove 61 corresponding to the excircle from rotating cam 60.This width deducts the width of block 55 corresponding to the width of the first cam face 53a of stationary cam 50.
[70] therefore, the part from the first inclined-plane 64a to the first cam groove 63a, the second cam face 62b and the second cam groove 63b have inwardly formed restraint drive cam surface 65, and it is to the height of the recessed degree of depth corresponding to block 55.
[71] as mentioned above, the width on restraint drive cam surface 65 is the excircle from the inner periphery of the part of the first inclined-plane 64a, the first cam groove 63a, the second cam face 62b and the second cam groove 63b to dihedral groove 61.The angle of circumference is about 220 °.
[72] on restraint drive cam surface 65, first inclined-plane 66a of restraint guiding and the central shaft of the first inclined-plane 64a are in same footpath upwards.The first cam groove 65a of restraint guiding extends out from the first inclined-plane 66a of restraint guiding in a circumferential direction.The first cam face 65b of restraint guiding extends out from the side of the first cam groove 65a of restraint guiding, forms the second inclined-plane 66b of restraint guiding therebetween.The second cam groove 65c of restraint guiding extends out from the side of the first cam face 65a of restraint guiding, forms the 3rd inclined-plane 66c of restraint guiding therebetween.
[73] on restraint drive cam surface 65, the central shaft of first cam groove 65a of restraint guiding and the first cam groove 63a of rotating cam 60 in same footpath upwards.The second inclined-plane 66b of restraint guiding is corresponding to the 4th inclined-plane 64d of rotating cam 60.The first cam face 65b of restraint guiding is corresponding to the second cam face 62b of rotating cam 60.The 3rd inclined-plane 66c of restraint guiding is corresponding to the 3rd inclined-plane 64c of rotating cam 60.The second cam groove 65c of restraint guiding is corresponding to the part of the second cam groove 63b of rotating cam 60.
[74] in addition, the first inclined-plane 66a of restraint guiding is corresponding to the first inclined-plane 64a of rotating cam 60.
[75] here, in restraint drive cam surface 65, the second cam groove 65c of the 3rd inclined-plane 66c of restraint guiding and restraint guiding can be in the same plane with the first cam face 65b of restraint guiding.
[76] having the stationary cam 50 of said structure and the mode of operation of rotating cam 60 makes the display unit of notebook computer carry out following angular motion.
[77] for example, the cam face of the cam face of stationary cam and rotating cam is engaged with each other.That is to say, suppose the right side of rotating cam and the left side engagement of stationary cam.But, for convenience of explanation, in the accompanying drawings, the left side of rotating cam and the engagement of the left side of stationary cam.
[78] as mentioned above, when the cam face of stationary cam 50 abutted against on the cam groove of rotating cam 60, the cam face and the cam groove that correspond to each other were engaged with each other.
That is to say that [79] the first cam groove 52a of stationary cam 50 is corresponding to the first cam face 62a of rotating cam 60, and be engaged with.The second cam groove 52b of stationary cam 50 is corresponding to the second cam face 62b of rotating cam 60, and is engaged with.The first cam face 53a of stationary cam 50 is corresponding to the first cam groove 63a of rotating cam 60, and is engaged with.The second cam face 53b of stationary cam 50 is corresponding to the second cam groove 63b of rotating cam 60, and is engaged with.
[80] certain, in this case, the first inclined-plane 54a of stationary cam 50, the second inclined-plane 54b, the 3rd inclined-plane 54c and the 4th inclined-plane 54d correspond respectively to the first inclined-plane 64a, the second inclined-plane 64b, the 3rd inclined-plane 64c and the 4th inclined-plane 64d of rotating cam 60.
[81] in this way, when stationary cam 50 and rotating cam 60 were engaged with each other, the block 55 of stationary cam 50 was near the first restraint drive cam groove 65a and the first restraint lead-in chamfered 66a in the restraint drive cam surface 65.
[82] still, as mentioned above, when the cam groove 52a of stationary cam 50 and 52b and cam face 53a and 53b fix and mesh with the cam face 62a of rotating cam 60 and 62b and cam groove 63a and 63b respectively, small gap may appear.
[83] that is to say, suppose that the cam groove 52a of stationary cam 50 and the cam face 62a of 52b and cam face 53a and 53b and rotating cam 60 and the complete engagement of 62b and cam groove 63a and 63b are the base unit 2 and the folding fully each other state of display unit 4 of notebook computer, thereby form zero (0) opening angle.In this case, if being upside down, carries notebook computer, when the cam groove 52a of stationary cam 50 and 52b and cam face 53a and 53b are in engagement with the cam face 62a of rotating cam 60 and 62b and cam groove 63a and 63b respectively, small gap may appear then.Therefore, when base unit 2 and display unit 4 are in complete folded state light activity can take place.
[84] therefore, in order not cause above-mentioned gap, as shown in Figure 9, when base unit 2 and display unit 4 are folding fully each other, when the opening angle that is base unit 2 and display unit 4 was zero (0), inclined- plane 64a, 64b, 64c and the 64d of rotating cam 60 and inclined- plane 54a, 54b, 54c and the 54d of stationary cam 50 were engaged with each other and form skew.Therefore, the continuous moment of torsion that internal friction power causes can stop display unit 4 to be moved with respect to base unit 2, unless apply the external force greater than this moment of torsion.
[85] that is to say, as above said, as the cam groove 52a of stationary cam 50 and cam face 62a and 62b, the cam face 53a of stationary cam 50 and the cam groove 63a and the 63b of 53b and rotating cam 60 of 52b and rotating cam 60, inclined- plane 54a, 54b, 54c and the 54d of stationary cam 50 aligns respectively with inclined- plane 64a, 64b, 64c and the 64d of rotating cam 60 and when being engaged with each other, and display unit 4 is adjusted to approximately-11 ° with respect to the angle of base unit 2.
[86] still, in fact display unit 4 can not fold into negative angle with base unit 2.When display unit 4 and base unit 2 were folded to form zero (0) opening angle fully, as shown in Figure 9, inclined- plane 64a, 64b, 64c and the 64d of rotating cam 60 and inclined- plane 54a, 54b, 54c and the 54d of stationary cam 50 were engaged with each other and form skew.Therefore, the continuous moment of torsion that internal friction power causes can stop display unit 4 to be moved with respect to base unit 2, unless apply the external force greater than this moment of torsion.
[87] in this way, when display unit 4 is folding fully with respect to base unit 2, if display unit 4 is mentioned greater than the power of above-mentioned moment of torsion and when upwards turning an angle, carriage 12 will rotate together along with display unit 4.Therefore, axle 20 is and then rotation also, makes rotating cam 50 rotations then.Certainly, in this case, because stationary cam 50 is fixedly connected on first carriage 32 of system's axle 30, and system's axle 30 is fixedly attached on the framework of base unit 2, so keep motionless.
[88] therefore, rotating cam 60 is with respect to stationary cam 50 rotations.The cam face 62a of rotating cam 60 and 62b are display unit 4 is done the angle rotation with respect to base unit 2 states along the cam face 53a of stationary cam 50 and the rotation of 53b.As mentioned above, because the cam face 62a of rotating cam 60 and 62b rotation in cam face 53a that pushes stationary cam 50 and 53b, therefore a plurality of springs 70 keep compression.Simultaneously, owing to produced moment of torsion, display unit 4 can not rotate freely with respect to base unit 2, but is maintained fixed on selected angle.
[89] according to the rotation of the angle of display unit 4, when the cam face 62a of rotating cam 60 and 62b in the cam face 52a of extruding stationary cam 50 and 52b during rotation, the block 55 of stationary cam 50 keeps its fixed positions.Simultaneously, the restraint drive cam of rotating cam 60 surface 65 allows block 55 not lock.
[90] that is to say, make the degree of depth on restraint drive cam surface 65 of rotating cam 60 identical with the height of block 55.Like this, when rotating cam 60 rotates with respect to stationary cam 50, just locking can not take place.
[91] on the other hand, as mentioned above, restraint drive cam surface 65 is formed at from the 4th inclined-plane 64a on the part of the second cam groove 63b, rather than on the whole circumference of rotating cam 60 (promptly 360 °).Therefore,, in other words, closely contact, then can not be further rotated with the sidewall that blocks of the second cam groove 63b if the sidewall of block 55 abuts against on the second restraint drive cam groove 65c on restraint drive cam surface 65.(please refer to Figure 11)
[92] in this way, when rotating cam 60 rotates to the block 55 embeddings second restraint drive cam groove 65c (end on restraint drive cam surface 65) of stationary cam 50, promptly the second cam groove 63b block sidewall the time, be display unit 4 is opened to about 150 ° of angles with respect to base unit 2 state.
[93] in addition, if display unit 4 is opened with respect to base unit 2 in opposite direction, when being closed to into 5 ° of angles with respect to base unit 2, display unit 4 can send click.
[94] that is to say, finish when contacting at the cam face 53a of the cam face 62a of rotating cam 60 and 62b and stationary cam 50 and 53b, when the inclined-plane of rotating cam 60 64a, 64b, 64c and 64d began to move on the inclined-plane of stationary cam 50 54a, 54b, 54c and 54d, sheet spring 70 recovered and produces to close click.
[95] certain, if being folded in fully, display unit 4 forms zero (0) degree on the base unit 2, then inclined- plane 54a, 54b, 54c and the 54d of inclined- plane 64a, 64b, 64c and the 64d of rotating cam 60 and stationary cam 50 are with the form locking of friction force.Simultaneously, the moment of torsion of generation is kept blocking, i.e. lock-out state is unless apply the external force that exceeds a certain size.
[96] heavy wear often may take place under the friction situation in stationary cam 50 and rotating cam 60.Therefore, preferably, cam adopts the stainless steel manufacturing of producing by well-known MIM technology, thereby improves its abrasion resistance.The MIM technology is the combination of plasticity injection moulding and sintering process, is suitable for producing in batches sophisticated product, as computing machine and electronic unit.

[97] as mentioned above, according to hinge means of the present invention, stop display unit and base unit to be opened each other by cam-engaged, even they are folding fully each other.Therefore, do not need independently blocking device, thereby, reduced manufacturing cost simultaneously for notebook computer provides simpler design.
[98] and, when display unit opens or closes with respect to base unit, can send click, thereby improve experience at certain angle.
[99] especially, when display unit is opened to base unit angled (about 150 °), can stops by the restraint function and further open.Therefore, can stop display unit to fall backward always, thereby improve performance with respect to base unit.
[100] though the present invention is illustrated with reference to specific illustrative embodiment, it is not limited to embodiment, but is only limited by appended claims.It is to be appreciated that those skilled in the art that and on the basis that does not exceed scope of the present invention and purport, to change these embodiments or to revise.
