In the embodiment shown in Fig. 6 and 7, be similar to the embodiment shown in Fig. 3, tensioner 420 is torsion springs.Torsion spring has relative free end 422 and relative fixed end 424, links together by spring coil 426.Spring coil 426 comprises one or more coiling rings, is placed on to be used for and fixed head 440 to be connected to one of post 126 that shell 120 combines.When spring coil 426 was connected to post 126, relative fixed end 424 was located in the depression 123 that forms in the inner surface of outer cover, rather than staggered relatively with the wall 128 that extends from the outward flange of last shell 120.The depression profile is corresponding to the basal surface of torsion spring.
First end of relative free end 422 engagement link 430 of tensioner 420 is corresponding to the back edge surface 432 of slide plate.Connecting rod 430 has engagement edge surface 436, is positioned at second end of slide plate, and it engages the contact point 418 of runner 410.In an illustrated embodiment, back edge surface 432 is relative with engagement edge surface 436.
Fig. 8 and 9 illustrated make position 110 (Fig. 8) and enable possition 210 (Fig. 9) each Fig. 6 and the front perspective view of 7 radio telephone 100.Figure 10 and 11 has illustrated the front perspective view of amplification of the upper housing portion of the radio telephone 100 shown in Fig. 8 and 9, corresponds respectively to open and make position.
Be similar to the embodiment shown in Fig. 3-5, the embodiment shown in Fig. 6-11 will finish the relative unlatching (that is rotation) of two housing parts of radio telephone 100 after manually beginning to rotate two housing parts.In addition, two embodiment will keep complete opening and complete make position similarly, and tensioner continues to apply power to connecting rod.
Be similar to the combination of the tensioner 320 and the bent axle 330 of Fig. 3-5 illustrated embodiment, the combination of tensioner 420 shown in Fig. 6-11 and slide plate 430 provides power to the eccentric contact point 418 of runner 410, and eccentric contact point 418 is usually with housing parts 120 and 220 deflection enable possitions.But the inclination that extends upward on the base portion 438 of V-arrangement profile on engagement edge surface 436 of the bigger inclination of arm or slide plate 430 makes the combination of tensioner 420 and slide plate 430 begin to be partial to complete make position.This be because, leave complete make position for contact point 418 rotation that makes runner 410, tensioner 420 needs further compression of beginning.
In Fig. 8-11, the path 419 of the eccentric contact point 418 of runner 410 has been described.In make position 110, in the circular path 419 of contact point 418, extend near the part on the engagement edge surface 436 of the base portion of V-arrangement profile.Extend in circular path 419 on engagement edge surface 436, up to a certain amount of angle of approach α of runner 410 rotations, shown in Fig. 2 and 10.In Figure 10, as can be seen, angle [alpha] is corresponding to the corresponding to point in the path of runner contact point and engagement edge surface, and it is consistent that the degree of the compression of tensioner 420 and tensioner are in the close position 110 o'clock compression at radio telephone 100.
But in the reality, after the inclination in the path 419 of contact point 418 surpasses the inclination on engagement edge surface 436 of slide plate 430, rotating machinery device 400 will be finished radio telephone 100 housing parts 120 and 220 rotations to enable possition 210 automatically.In an illustrated embodiment, the inclination in the path 419 of contact point 418 will surpass the inclination on engagement edge surface 436 on less than the angle of α.In shown embodiment, α is about 35 degree, more accurately, is 34.2 degree.In this, tensioner 420 is applied to power on the contact point 418 by connecting rod 430 and will makes contact point 418 relative motion and runner 410 rotations on the direction identical with the power that applies.
Except further compressing, needs tensioner 420 leaves complete closure and enable possition 110 and 210 to begin rotating upper and lower shell 120 and 220, in complete closure and enable possition, the contact point 418 of runner 410 and the center of runner 410 416 and the contact point conllinear 460 of connecting rod 430 at base portion 438 places of V-arrangement profile, thus, the power that applies by connecting rod 430 of tensioner 420 is perpendicular to the direction of motion of allowing of contact point 418 relative runners 410 rotations.Therefore, tensioner 420 power that is applied to contact point 418 can not cause producing any of runner 410 and rotatablely moves.
Rotation can be to begin clockwise or counterclockwise.And rotation can be used singlehanded the startup usually, and wherein, an example comprises: hold radio telephone 100 from rear side in user's palm, by user's thumb rotary flip, it stretches and stretches towards wireless telephonic front side around this side.
In addition, because the degree of length of spring compressed depends on housing parts absolute position relative to each other, and do not depend on the whole amount or the direction of motion, therefore to last shell 120 or renovate on the number of times of equidirectional rotation (always closed procedure is no matter direction is reloaded spring) without limits.
Although two shown embodiment have used torsion spring 320,420, it is connected to contact point 318,418 by connecting rod 330,430, and those skilled in the art should be easy to recognize, also can use the tensioner of other types.And tensioner also can comprise other interchangeable method similarly to the mode that runner applies power.For example, can make the power that pulley provides necessity that is spring-loaded, it may allow the greater flexibility on tensioner is placed.But, some other method may direction of rotation or on shell 120 or renovate aspect the rotatable in the same direction number of times so not flexible.
In addition, although in a preferred embodiment, the described here operation certainly in operating opening mechanism is described to be included in to a great extent the last shell 120 of radio telephone 100 or renovates, but, part operating opening mechanism 300,400 also can be arranged in the lower casing 220 or the fuselage of radio telephone 100, and this does not deviate from scope of the present invention.
