320, particularly be two

321, so that they can be inserted in the track female part 311 slidably with

320.

300 can comprise that also elastic force provides

330, and being used for provides elastic force to slide

320 about the slide of pedestal 310.Elastic force provides between the subtend face and

320 that

330 is installed in

310, and comprises wire spring.

For by reduce between

310 and the

320,

310 is with elastic force provides between the

330 and

320 and elastic force provide between the

330 slide with sliding

330 to rub accordingly to guarantee sliding

300 level and smooth and quiet slide, the

300 among the present invention comprises the minimizing unit that rubs.

In the sliding block according to first embodiment of the invention, it is to be coated in

320 lip-deep frictions to reduce coat that friction reduces the unit.It is to form by the material that coating has a lubricating ability that friction reduces

340, and can use such as materials such as silicon and reduce

340 as friction.

Direct friction between the track female part 311 of

310 and the

321 of

320 can reduce

340 by friction and reduce.

With reference to figure 4, can notice that

320 and elastic force provide direct friction between the

333 of

330 can rely on friction to reduce

340 and reduces.In addition, reduce

340 if form friction on the surface of

310, then the friction between

310 and the

333 will be reduced.The surperficial available silicon of

333 is coated with the friction of further minimizing

333 with

310 and

320.

As mentioned above, because between

310 and the

320,

310 and elastic force provides between the

330 and

320 and elastic force provide friction between the

330 to be rubbed to reduce

340 and reduces, so sliding

300 can be carried out more level and smooth and quiet slide.

In the sliding block according to second embodiment of the invention, the friction that friction reduces in the track female part 311 that the unit is mounted in

310 reduces

350.

With reference to figure 3, it is the bar shapeds of extending along longitudinally that friction reduces

350, and is installed in the track female part 311 with inserted mode along longitudinally.Reducing the surperficial upper edge longitudinally formation rail groove 353 that the

321 of

350 contact with friction, and the

321 of

320 is inserted in slidably in the rail groove 353, and along leading on the certain altitude of rail groove 353.

Friction reduces

350 and is inserted into the friction between the

321 of the track female part 311 that reduces

310 and

320, and preferably makes with the material of a certain strength grade that is used for the impact that friction resistant causes with itself having lubricating ability.For this reason, can use engineering plastics to be used as friction and reduce

350 with lubricating ability and a certain strength grade.Polytype engineering plastics are arranged, and the POM (polyformaldehyde) that for example has this two specific character is suitable for.

Friction reduces

350 and can be coupled with track female part 311 in every way.In one approach, can be configured to reduce coupling projection 351 that

350 protrudes and admit recesses form male part with coupling protruding 351 projectioies corresponding, that coupling projection 351 can be inserted wherein in that track female part 311 is that form by comprising from friction.By this male part, friction reduces

350 can firmly be fixed, and can not move along the longitudinally of track female part 311.In a kind of diverse ways, friction reduce

350 can with

310 in couples injection molding together so that they can integrally be constituted and need not to be coupling in together.Equally, in this case, can form projection in advance at track female part 311 places and admit recess 312, can firmly be kept with the coupling of track female part 311 so that friction reduces

350.

With reference to figure 4, the track female part 311 of

310 becomes indirect friction with the direct friction of the

321 of slide block 320.In view of the above, the friction between the track female part 311 of

310 and the

321 of

320 can be reduced, and thus, sliding

300 can the operation slidably of more level and smooth and quiet ground.

The two end portions that reduces

350 in friction is mounting

360 in addition, certain member of sliding

300 being installed with buffering (for example, second fuselage, i.e. 200 among Fig. 1) and friction reduce between the

350 collision in the moment that

320 stops to slide.

Preferably, the friction of

350 usefulness such as rubber or polyurethane geometric ratio reduces

350 rubber or polyurethane more smooth and that be easy to absorb impact and makes.Be used for

360 be coupled to end male part that friction reduces

350 comprise by cut away friction reduce

350 the end and in the end 352 ends projection 352a that form and the end recess 361a that forms at the prolongation of end buffer component 360.In other words, the end projection 352a that reduces

350 when friction is during with the end recess 361a coupling of inserted mode and

360, and

360 just can be coupled with friction minimizing member 350.At this moment, cut away part 313,

360 is installed to these cuts away part 313 in the two end portions formation of track female part 311.Thus,

360 projection on the angle of the two end portions of

310 slidably.

In the

300 according to third embodiment of the invention, it is to provide realizing from structure of

330 by elastic force that friction reduces the unit.

With reference to figure 2 and 3, elastic force provide

330 to comprise to be configured to mutually in the face of ground from the

331 of the first type surface of

310 and

320 projectioies and 332 and two end portions by

331 and 332

333 that support.

333 is wire springs, and comprise winding part 333a, be used for by gather elastic force to reel with the form of closed bending (that is, with circular pattern) from the middle part, and comprising hook portion 333b, it is reeled with circular pattern and is coupled to be supported by

331 and 332 in two end portions.

At this, form two winding part 333a at least.This two winding part 333a complementation, its position are not tilted to

310 or slide block 320.In other words, these two winding part 333a are balance on strength, and winding part 333a only operates on the plane that originally they be arranged probably.Therefore, winding part 333a is very little to the possibility of

310 or

320 inclinations.

Preferably, each winding part 333a only reels once with the form of closed bending.When winding part 333a reels twice or repeatedly the time, spring will form sandwich construction at winding part, when operating spring, its can (' H ' among Fig. 4) fluctuate on the direction vertical with the first type surface of

310 or slide block 320.But in the present invention, the winding part 333a of

333 only reels once, so it can not fluctuate, thereby can reduce the friction with the first type surface and the

320 of pedestal 310.In addition, the thickness of

333 on ' H ' direction that winding part 333a only reels once is very little, thereby sliding

300 total thickness can be reduced.

It is a pair of that elastic force provides

330 to be constituted as, and this provides

330 to face mutually to elastic force, and arrange symmetrically based on center line (' C ' among Fig. 5) therebetween.When operation elastic force when the

333 of

330 is provided, this type of layout will can be to lopsidedness, and this has just reduced the friction with

310 or slide block 320.Construct at least one or a plurality of winding part 333a, and preferably, on the meaning of operation, two winding parts are preferable.

With reference to figure 4, because elastic force provides

330 to comprise only reel once

333 of winding part 332a, so it does not have very great fluctuation process on ' H ' direction, therefore the friction with

310 or

320 can be reduced.In addition, because this provides

330 to be arranged to approximate hexagon to elastic force, so they will can be to lopsidedness 320 of

310 and slide blocks, this just can prevent the friction level increase.In addition, be to realize because the friction among the present invention first and second embodiment reduces the function of unit, so friction reduces

340 or friction to reduce

350 optional in those embodiment by the structures of

333 itself.

In the fourth embodiment of the present invention, the function that the friction of sliding

300 reduces the unit is to have the fact of different separately coefficient of frictions to realize by

310 and

320.

Generally speaking, each have in the situation of different coefficient of frictions at the member of two contacts, the friction between these two members will be littler than the friction that two members have in the situation of same friction.Based on this principle,

310 is made so that it has different separately coefficient of frictions with the different material of

320 usefulness.Thus, the friction between

310 and the

320 can be reduced, and therefore, operation noise also can be lowered.

To reduce the unit different with friction among first and second embodiment of the present invention, and above-mentioned the 3rd embodiment of the method and the present invention is the same to be favourable, because it need not reduce

340 and friction reduces extra structure such as

350 grades such as friction.

Fig. 5 and 6 illustrate and pedestal and slide block between the corresponding relative position relation of slide.Particularly, Fig. 5 illustrates the state that slide block 320 moves up on

310, and Fig. 6 illustrates the state that slide block 320 moves down on

310.

When as above described execution during slide (as shown in Fig. 5 and 6) between

310 and slide block 320 with reference to each embodiment, an operation or its combination operation of relying on friction to reduce unit (structure, the friction that friction reduces

340 reduces the material that

350 and elastic force provide

330 and

310 and slide block 320) are reduced friction, and the slide relative between these two positions can be carried out more level and smooth and quietly.

With reference to figure 7 and 8, on the

202 of

200, form slide block installed

202a, slide block 320 ' is installed on it.The other parts of the aspect ratio

202 of slide block installed

202a are low, so that

320 '.Slide block installed

202a and slide block 320 ' comprise respectively and cut out

202e and 320 ' d that the holding wire (not shown) between

100 and

200 can connect by these parts.

At this, if

202 is coupled fully with slide block lid 320 ' and does not allow that arranged any separation therebetween, then slide block 320 ' will can not fluctuate, thereby any collision (or friction) will can not take place.Therefore, for this purpose, between slide block 320 ' and

202, can construct fixture.

In portable terminal according to an embodiment of the invention, fixture comprises from the fixed lobe 320 ' c of the two end portions protrusion of slide block 320 ' and the

202b that forms at

202 corresponding to fixed lobe 320 ' c.Preferably, fixed lobe 320 ' c and fixedly recess 202b form at slide block 320 ' and

202 place, two ends along longitudinally.Reason is because slide block 320 ' is constructed to extend along longitudinally, so the possibilities of the two end portions of slide block 320 ' 202 separation along longitudinally from lower cover are higher relatively.

When slide block 320 ' when slide block installed

202a presses, thereby fixed lobe 320 ' c is pushed and is inserted into fixedly among the recess 202b.Thus, fixed lobe 320 ' c and fixedly

202b can be coupled easily according to the hasp method.

Coupling process between slide block 320 ' and the

202 is favourable, because this coupling process is very easy, and slide block 320 ' can not separate from lower cover 202.Thus, during the slide of sliding

300, can be reduced, therefore, can guarantee the operation that sliding

300 is level and smooth and quiet because of slide block 320 ' correctly is fixed on the collision, friction or the noise that produce on the lower cover 202.In addition, because first between slide block 320 ' and the

202 coupling is to finish by easy coupling process, so when using screw to wait to carry out second coupling, slide block 320 ' can advantageously align simultaneously with

202.

In portable terminal in accordance with another embodiment of the present invention, fixture comprises from a side of

202 towards slide block 320 ' fastening first fastening unit and towards second fastening unit fastening with the first fastening unit rightabout.

First fastening unit comprises respectively at

202 and slide block 320 ' goes up the

202c that forms and 320 ' and

410 that penetrates the

202c and 320 ' a such as court such as screws from the direction of

202 past slide blocks 320 '.

Second fastening unit comprises respectively

420 of going up the

202d that forms and 320 ' b and penetrating the

202d and 320 ' b such as edge such as screws from the direction of slide block 320 ' past

202 at

202 and slide block 320 '.

Because fastening in the opposite direction

202 of first and second fastening units and slide block 320 ', so compare with the fastening situation of equidirectional with slide block 320 ' with

202, slide block 320 ' and

202 can more firmly make up, and keep long time.In view of the above, because slide block 320 ' suitably is fixed on the

202, so can guarantee that sliding

300 is level and smooth and operate quietly.

In the above description, track female part 311 is built into

310 places, and

321 is built into

320 and 320 ' and locates, but opposite structure also is possible.Equally,
