Embodiment
Embodiment describes the present invention in detail with reference to the accompanying drawings.
Fig. 1 to Fig. 6 is the open-close device for sliding cover figure of the portable terminal device of one embodiment of the invention, wherein, Fig. 1 is the plane graph that has adopted the portable terminal device of apparatus of the present invention, Fig. 2 is the side view that has adopted the portable terminal device of apparatus of the present invention, Fig. 3 and Fig. 4 are the plane graphs that the open-close device for sliding cover of portable terminal device constitutes and acts on, Fig. 5 is the structure oblique view of sticking department, and Fig. 6 is pneumatic cylinder partial structurtes profiles.
As shown in the figure, it comprises following several sections: the 1st accommodation section (110) and the 2nd accommodation section (120), and both combine, and can open, close in the mode that mobile terminal device body (100) slides mutually; Air pressure is opened portion (200), and above-mentioned the 1st accommodation section (110) and the 2nd accommodation section (120) are opened under cylinder (210) pressure effect; Sticking department (300) makes above-mentioned the 2nd accommodation section (120) stay in the position of closing.
Above-mentioned the 1st accommodation section (110) is equipped with display unit (101) such as liquid crystal board, in the 2nd accommodation section (120) a plurality of buttons (102) is installed.
And, in above-mentioned the 1st accommodation section (110), having guide rail (240), the 2nd accommodation section (120) are upwards opened downwards, are closed in the longitudinal direction along guide rail (240).
For the 1st accommodation section (110), also can be by other morphosis, the structure that the upper and lower straight line in the 2nd accommodation section (120) moves and opens, closes also can be to use other form of common slide construction.
Above-mentioned air pressure open portion (200) be a countercylinder (210) secured in parallel in the 1st accommodation section (110), in above-mentioned the 2nd accommodation section (120), fix the driving member (220) that the piston (212) of above-mentioned both sides cylinders (210) is connected, be fixed with guide vane end stop (230), (231) respectively in above-mentioned the 1st accommodation section (110) and the 2nd accommodation section (120).
The piston (212) of said cylinder (210) inserts cylinder block (211), in the inner of piston (212) in conjunction with caulking gum (213).
Above-mentioned sticking department (300) is made of following several sections: rocking bar (310), and it is fixed on a side of above-mentioned the 2nd accommodation section (120), and its inner has inclined plane (311); Fixture block (320), it is incorporated into the driving member (220) of the 2nd accommodation section (120) and goes up on the formed guiding groove (221), and can move by straight line; Spring (330), it is the above-mentioned fixture block of resiliency supported (320) laterally; Drive link (340), it is incorporated into the 2nd accommodation section (120) one side sidewalls (111) and goes up in the formed bullport (112), and can move left and right, in order to remove the locking of above-mentioned fixture block (320); Action button (350), it is fixed in drive link (340) outer end.
The piston (212) of said cylinder (210) can carry out 1 degree of freedom reciprocating motion.Therefore, for the 1st accommodation section (110), if manual-lock the 2nd accommodation section (120), piston (212) obtains potential energy (Potential-Energy) when carrying out compression movement so.
Said cylinder (210) is utilized the principle of pressure (P) * volume (V)=constant (const), change in order in driving, to reduce internal pressure (P), as shown in Figure 6, make the shape of enlarged portion (214), reduced the overall volume rate of change at the end of cylinder block (211).
The effect that is incorporated into the inner caulking gum (Sealing Rubber) (213) of piston (212) is to stop the gas leakage that occurs because of atmospheric pressure and cylinder block (211) internal pressure difference.And, used lubricating oil at the friction part of caulking gum (213), reduce to drive friction, make sealing (Sealing) effect at position, pressure boundary reach maximum.
Required power when driving the 2nd accommodation section (120) and open and close with respect to above-mentioned the 1st accommodation section (110) has considered that the pressure by the decision of cylinder block (211) change in volume changes function, needs an integral equation.But, if supposition does not have the cylinder internal change in volume, use F=Δ P * A formula from the hydrostatics viewpoint so, can list putting on the equilibrium of forces equation of renovating simply.
The cylinder sectional area of F=cylinder number * (cylinder pressure and atmospheric pressure poor) * drive division-the renovate frictional force when driving
Like this, determined cylinder number, cylinder diameter, cylinder internal pressure etc., can obtain the power that is subjected to of renovating, according to renovating round distance, decision opening and closing speed and the impulsive force when stopping to be carried out perception design.
Fig. 3 has shown the 2nd accommodation section (120) with respect to the 1st accommodation section (110) closing state, and at this moment the piston (212) of cylinder (210) is compressed.
In this state, if by action button (350), drive link (340) is pushed to the inboard so, fixture block (320) moves to the inside, so deviate from from rocking bar (310) the 2nd accommodation section (slip lid) (120), the piston (212) of cylinder (210) is upheld under the pressure differential effect, this piston (212) promotes driving member (220), so as shown in Figure 4, open to downside the 2nd accommodation section (120).
On the contrary, when closing the 2nd accommodation section (120) under the state at Fig. 4, if upwards push away the 2nd accommodation section (120), so, the piston (212) of cylinder (210) is when carrying out compression movement, cylinder (210) internal pressure raises, the fixture block (320) that is incorporated on the driving member (220) of the 2nd accommodation section (120) is promoted by the inclined plane (311) along rocking bar (310), simultaneously, the 2nd accommodation section (120) moves to the upper strata, behind fixture block (320) the process rocking bar (310), drive link (340) and action button (350) set back, and keep open mode as shown in Figure 3.
During driven opening, the round distance of the piston (212) of cylinder (210) and both sides guide vane end stop (230) as shown in the figure, the distance between (231) is identical.
Above-mentioned lock mode both can use following structure, that is, actuating force driving member (220) has the degree of freedom with respect to left and right directions, was incorporated into sliding part simultaneously and carried out relative motion, went up or unlocked so that be stuck in rocking bar (310).Also can use following structure, that is, the left and right directions degree of freedom of driving member (220) utilizes spring to locate.
As the above-mentioned explanation of doing, the open-close device for sliding cover of portable terminal device of the present invention is potential energy (Potential-Energy) characteristic of accumulation that utilizes compressibility gas (pneumatic), can open driving automatically, so have the advantage that improves ease of use.And, owing to do not need other power, also have the advantage of saving battery supply, increasing the service life.
