Course of action below in conjunction with 1 pair of multiple torque spring of embodiment of the present invention of said structure is described.
Fig. 5 a is the slide mass 92 according to mobile communication terminal, makes the main body 91 of mobile communication terminal present closed phase diagram; Fig. 5 b is half mobile status figure of the slide mass 92 of mobile communication terminal; Fig. 5 c is the slide mass 92 through the slip mobile communication terminal, makes the main body 91 of mobile communication terminal present the phase diagram of opening.
Shown in Fig. 5 a, said elastomer 100 diagonals are arranged on the main body 91 of said mobile communication terminal, and its left-hand end is fixed to the slide mass 92 of said mobile communication terminal, and its right-hand end is fixed on the main body 91 of said mobile communication terminal.
Shown in Fig. 5 b, when the slide mass of said mobile communication terminal 92 was slided to the right side, the left-hand end of the said elastomer 100 that then is connected with the slide mass 92 of said mobile communication terminal was mobile to the right and compress said heliconid.
At this moment, said the 1st heliconid 111, said the 2nd heliconid 121 and said the 3rd heliconid 131 is stressed evenly expands with identical ratio respectively, and mutual noninterference.
Shown in Fig. 5 c; The maximum compression control point of said elastomer 100 (Compression Kneepoint); Be that the left-hand end of said elastomer 100 is when surpassing the vertical line of right-hand end; Because said spirochetal elastic restoring force, the left-hand end of said elastomer 100 are slided to the right automatically, this just causes mobile communication terminal slide mass 92 also to slide automatically.
At this moment, the elastic force of said the 1st heliconid 111, said the 2nd heliconid 121 and said the 3rd heliconid 131 is concentrated to the right ends of said elastomer 100, and the elastic force of said elastomer 100 is increased.
As stated; Had by at least more than one that spirochetal elastomer 100 constitutes, the heliconid of each elastomer 100 has different radiuses and is positioned on the concentric circle, and the length that makes wire rod is in the longest state but makes its thickness be contracted to minimum; This just makes the spring attenuation; Can increase elastic force again, and prevent interfering with each other of each spring, make its action smooth and easy flexibly.
