As shown in Figure 4, axle 3 forms general rod shaped.Axle 3 is provided with lip part 31.Lip part 31 is provided with engaging recessed part 15.Engaging recessed part 15 for example forms to its radially inner side excision by the part with the peripheral portion of lip part 31, but is not limited thereto.
The part from these 31 to ends of lip part of axle 3 forms as the first axle part.The first axle part is made of the 3a of first portion of the first axle part, the second portion 3b of the first axle part and third part 3c three parts of the first axle part successively from 31 to ends of lip part.The 3a of first portion of the first axle part and lip part 31 are positioned on the same axle, and form diameter round-shaped less than the diameter of lip part 31.The second portion 3b of the first axle part forms the substantially elliptical shape, and opposed two positions that this ellipse has the 3a of first portion with the first axle part a circle of same diameter are excised abreast and formed.The third part 3c of the first axle part forms the substantially elliptical shape, and this ellipse excises the part of the parallel excision of the second portion 3b of the first axle part more longways than the second portion 3b of the first axle part and forms.
In addition, the part from lip part 31 to another end of axle 3 forms as the second axle part 3d.This second axle part 3d forms the substantially elliptical shape, and this elliptical shape is excised diameter abreast less than the diameter of lip part 31 and greater than opposed two positions of the circle of the diameter of the 3a of first portion of the first axle part and formed.Second carriage 4 is installed on this second axle part 3d.
For example, constitute friction torque parts 5 by fixed friction sheet 61,62, rotating friction plate 71,72 and belleville spring 8 as Fig. 2, Figure 12 and shown in Figure 13.When axle 3 rotated with respect to first carriage 2, these friction torque parts 5 produced friction torque, thereby can be with respect to first housing 11 with arbitrarily angled maintenance second housing 12.That is, friction torque parts 5 constitute to have: fixed friction sheet 61,62, and they can be along the moving axially of axle 3, and can rotate around axle 3, and be constrained on first carriage 2; Rotating friction plate 71,72, they can be along the moving axially of axle 3, and rotate with axle 3; With a plurality of belleville springs 8, they make fixed friction sheet 61,62 and rotating friction plate 71,72 in the axial direction each other pressure contact.
As long as fixed friction sheet 61,62 can be along the moving axially and can rotate around axle 3 of axle 3, and be constrained on first carriage 2, then be not particularly limited.Fixed friction sheet 61,62 for example be installed in axle 3 the first axle part second portion 3b around, and form roughly discoideus.As shown in Figure 6 and Figure 7, on fixed friction sheet 61,62, be provided with through hole 61a, the 62a of diameter and the diameter identical (comprising roughly the same) of the second portion 3b of the first axle part coaxially, run through to be inserted among this through hole 61a, the 62a by the second portion 3b that makes axle 3 the first axle part, fixed friction sheet 61,62 just be installed in axle 3 the first axle part second portion 3b around.
In addition, the part of the circumferential part of fixed friction sheet 61,62 is stretched out to radial outside, and this front end that stretches out is bent into the right angle, thereby as i.e. second snap-latch piece, 63,64 formation in second engagement portion that engages with first card complex hole 27 of first carriage 2.This snap- latch piece 63,64 engages with first card complex hole 27 of first carriage 2 respectively, and fixed friction sheet 61,62 is constrained on first carriage 2 thus, thereby only with moving axially along axle 3.
The number of fixed friction sheet both can be that a slice also can be more than two, but preferably two or three.Under the situation of fixed friction sheet of configuration more than two,, preferably dispose the fixed friction sheet respectively in the both sides of the axle support 23 of first carriage 2 as Fig. 2 and shown in Figure 12.For example, at two fixed friction sheets 61 of configuration, under 62 the situation, a slice fixed friction sheet (being sometimes referred to as the first fixed friction sheet 61) is configured between the axle support 23 and lip part 31 of first carriage 2, another sheet fixed friction sheet (being sometimes referred to as the second fixed friction sheet 62) is configured in the opposition side of lip part 31 with respect to the axle support 23 of first carriage 2, these two fixed friction sheets 61,62 second snap-latch piece 63, as long as 64 position can engage with first card complex hole 27 of first carriage 2, be not particularly limited, can be identical position, also can be different position as shown in the figure.In addition, the constraint of fixed friction sheet 61,62 on first carriage 2, and only limit to first card complex hole 27 and second snap- latch piece 63,64, also can use other engaging method.
Rotating friction plate 71,72 is not particularly limited, and for example is pad of forming of the metallic material by the excellent in wear resistance of hard etc.Rotating friction plate 71,72 can be along the moving axially of axle 3, and rotate with axle 3, and wherein a slice and lip part 31 disposed adjacent, and preferably, rotating friction plate 71,72 is configured in the both sides of fixed friction sheet 61,62 respectively.Promptly, rotating friction plate 71,72 for example is configured between lip part 31 and the first fixed friction sheet 61 respectively, between the first fixed friction sheet 61 and the axle support 23, between axle support 23 and the second fixed friction sheet 62 and a side second fixed friction sheet 62, opposite with axle support 23, add up to and dispose four.
The rotating friction plate adjacent with lip part 31 is second rotating friction plate 72, and the rotating friction plate (being sometimes referred to as first rotating friction plate 71) beyond this second rotating friction plate 72 forms roughly the same discoideus of the diameter of diameter and fixed friction sheet 61,62.As shown in Figure 9, this first rotating friction plate 71 is provided with the through hole 71a of essentially rectangular shape.This through hole 71a forms with the straight section that extends in parallel of the second portion 3b of axle 3 the first axle part and cooperates, first rotating friction plate 71 can along axle 3 moving axially and with axle 3 rotations.
Second rotating friction plate 72 is installed on the 3a of first portion of axle 3 the first axle part, for example is the pad that forms of the metallic material by the excellent in wear resistance of hard etc.Second rotating friction plate 72 forms roughly the same roughly discoideus of the diameter of the diameter and first rotating friction plate 71.As shown in Figure 8, second rotating friction plate 72 is provided with round-shaped through hole 72a.The part of the peripheral portion of this second rotating friction plate 72 is formed as snap-latch piece 16 thereby the middle body after this excision is bent into the right angle by the excision of linarity ground.This snap-latch piece 16 engages with the engaging recessed part 15 of lip part 31, and its width forms the size roughly the same with the width of engaging recessed part 15.Thus, second rotating friction plate 72 rotates with axle 3.In addition, in Fig. 8 and Fig. 9, label 72b, 71b represent the lubricating grease reservoir respectively.
Belleville spring 8 be used to make fixed friction sheet 61,62 and rotating friction plate 71,72 in the axial direction each other pressure contact.Belleville spring 8 be arranged on the first axle part third part 3c around.As shown in figure 10, belleville spring 8 is springs of dish, for example forms diameter roughly discoideus less than the diameter of rotating friction plate 71,72 slightly.Belleville spring 8 is provided with and runs through the round-shaped axis hole 8a that inserts axle 3 (the third part 3c of the first axle part).The installation number of belleville spring 8 is determined arbitrarily according to desirable friction torque, for example is ten.These belleville springs 8 are with spring series connection (involutory) configuration of in parallel (superimposed) in twos, for example, are under ten the situation, with five groups of spring arranged in series in parallel in twos at belleville spring 8.
As Fig. 2, Figure 11 and shown in Figure 12, compress gasket 13 is installed in the end that these belleville springs 8 are installed of axle 3.This compress gasket 13 is provided with the roughly axis hole 13a of oval shape, and axle 3 (the third part 3c of the first axle part) run through insertion and are entrenched among this axis hole 13a.By axle 3 (the third part 3c of the first axle part) are run through among the axis hole 13a that is inserted into this pad 13, and rivet the end of this axle 3 (the third part 3c of the first axle part), belleville spring 8, fixed friction sheet 61,62 and rotating friction plate 71,72 just are installed on the axle 3, and by the active force of belleville spring 8, fixed friction sheet 61,61 and rotating friction plate 71,72 and axle support 23 are close to each other.When this axle 3 rotates, between fixed friction sheet 61,62 that rotates with the rotation of axle 3 and rotating friction plate 71,72, produce the frictional force of thrust direction, thereby produce friction torque.Though use compress gasket 13 is installed in belleville spring 8, fixed friction sheet 61,62 and rotating friction plate 71,72 on the axle 3 and produces friction torque, but be not limited thereto, thread groove also can be set in the end of axle 3 and screw nut in this end and wait and install.
Below, the effect of incline hinge 1 of the present invention and electronic equipment 10 is described.
Under the closed state that electronic equipment 10 is not used, first housing 11 and second housing 12 overlap.At this moment, because the active force of belleville spring 8, fixed friction sheet 61,62 and rotating friction plate 71,72 are close to, so first housing 11 and second housing 12 are kept closed.In addition, in order to keep this closed state more reliably, also other locking framework can be set.
Using under the situation of this electronic equipment 10, for example, under the state that first housing 11 is fixed, to make it will serve as the power that axle rotates with axle 3 in 12 effects to second housing.At this moment, second housing 12 serves as the axle rotation with respect to first housing 11 with axle 3, and rotating friction plate 71,72 slides with respect to fixed friction sheet 61,62.For example, if be made as 0 ° when first housing 11 and second housing 12 overlapped, then this is rotated in 0 °～180 ° the scope and is rotated.
Thus, when making second housing 12 with respect to 11 rotations of first housing, between fixed friction sheet 61,62 that rotates with the rotation of axle 3 and rotating friction plate 71,72, produce the frictional force of thrust direction, thereby generation friction torque, so when second housing 12 is stopped the rotation, because this friction torque, second housing 12 just stops at this position.Thus, can make second housing 12 stop at desirable angle in 0 °～180 ° the scope with respect to first housing 11.Its result is that the keyboard 11a that is arranged on first housing, 11 upper surfaces exposes, and therefore can carry out keyboard operation, thereby can use electronic equipment.
In order to make second housing 12 return origin-location (closed state) with respect to first housing 11, for example under the state that first housing 11 is fixed, making second housing 12 serves as axially to rotate with above-mentioned opposite direction with axle 3, can turn back to the closed state that first housing 11 and second housing 12 overlap thus.
And, under the situation that produces high friction torque, as long as increase the sheet number of fixed friction sheet, for example as shown in figure 12, can between lip part 31 and axle support 23, dispose a slice fixed friction sheet 65 again and promptly add up to two fixed friction sheets of configuration, also can dispose the fixed friction sheet that a slice promptly adds up to two with respect to axle support 23 again at the opposition side of lip part 31 as shown in figure 13.Thus, the surface of contact that can further increase fixed friction sheet 61,62,65,66,67 and rotating friction plate 71,72 is a slip surface, therefore can produce higher friction torque.
In addition, the fixed friction sheet is not particularly limited with first the engaging of carriage 2, for example can be as shown in figure 12, make to be configured in lip part 31 and the two slice fixed friction sheets 62,65 of axle between the support 23, and a slice fixed friction sheet 61 that is configured in the opposition side of lip part 31 with respect to axle support 23 engages with first card complex hole 27 respectively.In addition, for example also can be as shown in figure 13, make to be configured in lip part 31 and to engage with first card complex hole 27, and the two fixed friction sheets 66,67 that are configured in the opposition side of lip part 31 with respect to axle support 23 are engaged with other engagement portions of first carriage 2 with a slice fixed friction sheet 62 of axle between the support 23.
In addition,, just high friction torque can be produced, for example,, high friction torque can be exported by with five groups of ten belleville springs 8 back in parallel in twos arranged in series if strengthen the active force of belleville spring 8.Specifically, for example by thickness being approximately five groups of ten belleville springs 8 back in parallel in twos arranged in series that 0.65mm, diameter are approximately 6.5mm, and use diameter to be approximately the fixed friction sheet 61,62 of 7mm and the rotating friction plate 71,72 that diameter is approximately 7mm, can produce the high friction torque that is approximately 1Nm (approximately 100Kgmm).
Belleville spring 8 passes through five groups of back in parallel in twos arranged in series, can shorten axial length.This be because, if ten belleville springs are replaced one by one (individually polyphone) configuration, compare with the situation of five groups of arranged in series after the parallel connection in twos, axial length is elongated, and active force is more weak than the situation of five groups of in parallel back arranged in series in twos, therefore, for obtain with in parallel in twos after identical active force during five groups of arranged in series, must increase the number of belleville spring, and then cause axial length elongated.
In addition, under situation with ten belleville springs (superimposed) all in parallel configuration, because belleville spring is assembled on the axle like this: ten belleville springs are installed to axle 3 around after, push these belleville springs with the power that the active force that overcomes these springs is exported more than the desirable friction torque to the rotating friction plate side, therefore, if belleville spring is superimposed more than three, then the active force of the belleville spring of the active force of three belleville spring integral body and the simple thickness that is equivalent to three belleville springs is roughly the same, overcoming the belleville spring distortion that active force made superimposed more than three needs very big power, therefore can not easily carry out the assembling of belleville spring.Relative therewith, in incline hinge 1 of the present invention, because belleville spring 8 is the belleville spring arranged in series of parallel connection in twos, thus do not need very big belleville spring 8 distortion that the clothes active force just can not make parallel connection in twos of making every effort to overcome, so can simply belleville spring 8 be assembled on the axle 3.
In addition, owing to the lip part 31 of second rotating friction plate 72 with axle 3 engages, thus suppressed between second rotating friction plate 72 and lip part 31, to produce loosening situation, and assembling operation becomes easy.Promptly, by on the lip part 31 of axle 3, engaging recessed part 15 being set, on second rotating friction plate 72, snap-latch piece 16 is set, and thereby this snap-latch piece 16 is side-prominent so that rotate with engaging recessed part 15 engagings and axle 3 to lip part 31, thus, when axle 3 rotated, the snap-latch piece 16 of second rotating friction plate 72 engaged with the engaging recessed part 15 of lip part 31, second rotating friction plate 72 rotates with axle 3, has therefore suppressed to produce between second rotating friction plate 72 and lip part 31 loosening situation.In addition, because second rotating friction plate 72 does not need moving axially along axle 3, so in the prior art, by being pressed into to be installed to it is rotated with axle rotating friction plate, but in the present invention, as long as the snap-latch piece 16 of second rotating friction plate 72 is engaged with the engaging recessed part 15 of lip part 31, so, just needn't be pressed into and to install second rotating friction plate 72 being installed under the situation on every side of axle 3.Consequently, the assembling operation of second rotating friction plate 72 becomes easy.
Therefore, in incline hinge 1 of the present invention and electronic equipment 10, can increase the slide area between axle 3 and first carriage 2, and shorten axial length and radial length, and,, incline hinge of the present invention 1 and electronic equipment 10 rub and miniaturization exportable high friction torque so can realizing height because the snap-latch piece of second rotating friction plate engages with the engaging recessed part of the lip part of axle, and the generation that can suppress to become flexible, and can easily carry out assembling operation.
