Embodiment
Now cooperate graphic explanation preferred embodiment of the present invention.
See also Fig. 2 A, will use same label with existing CD-ROM drive 1 components identical.CD-ROM drive 2 of the present invention mainly comprises upper shell 11, lower house 12, body 13, circuit board 14, clamping piece structure 25, rotation motor 16, pallet 17 and panel 18.Body 13 and circuit board 14 are folded between upper shell 11 and the lower house 12, rotation motor 16 is arranged in the body 13 and with circuit board 14 and is electrically connected, pallet 17 movably is arranged between upper shell 11 and the body 13, clamping piece structure 25 is arranged at upper shell 11, and panel 18 is covered in a side of upper shell 11, lower house 12 and body 13.Wherein, discs D is positioned on the pallet 17, and when circuit board 14 transmission signals made rotation motor 16 drive discs D rotation, clamping piece structure 25 and rotation motor 16 were with common chucking optical disk sheet D.
See also Fig. 2 B again, clamping piece structure 25 of the present invention comprises a central portion 251 and a plurality of cantilever 252, and central portion 251 is rounded substantially, and cantilever 252 is a strip, around central portion 251, and the stiff end of each cantilever 252 is connected with central portion 251 a plurality of cantilevers 252 with radial.
Perhaps, what clamping piece structure 25 of the present invention can be looked is to comprise a central portion 251 and a plurality of teat (being equal to above-mentioned cantilever 252), and a plurality of jag is looped around the periphery of central portion 251.
Perhaps, also clamping piece structure 25 can be looked for comprising a central portion 251 and a plurality of breach (crack) C, breach C is around outer rim (circumference) R of the central portion 251 of clamping piece structure 25.Below will go on to say the CD-ROM drive and the clamping piece structure thereof of this case based on the embodiment of cantilever 252.
In addition, shown in Fig. 2 B, the central portion 251 of clamping piece structure 25 is provided with projection 253, in order to be connected with rotation motor 16.
Fig. 2 C shows the partial interior structure cutaway view of CD-ROM drive 2 of the present invention, by on the figure as can be known, after CD-ROM drive 2 assemblings are finished, clamping piece structure 25 is arranged in the holding part 111 of upper shell 11, and the cantilever 252 of clamping piece structure 25 is covered on upper shell 11, simultaneously, upper shell 11 has loam cake 112, in order to cover holding part 111 and clamping piece structure 25.
See also Fig. 2 D again, the partial interior structure cutaway view that shows CD-ROM drive 2 of the present invention, by on the figure as can be known, be positioned over the pallet 17 of CD-ROM drive 2 as discs D, and after pallet 17 enters between upper shell 11 and the body 13, rotation motor 16 will improve a distance makes the projection 253 of clamping piece structure 25 be connected with the pilot hole 161 of rotation motor 16, and the magnet 254 in the central portion 251 of clamping piece structure 25 attracts each other with rotation motor 16, to strengthen the strength of clamping and fixed light disc D, simultaneously, rotation motor 16 and discs D replace clamping piece structure 25 and make and produce a space S between the cantilever 252 of clamping piece structure 25 and the upper shell 11, afterwards, circuit board 14 just can transmit signal makes rotation motor 16 drive discs D, carries out the running of CD-ROM drive 2.
In above-mentioned, because the clamping piece structure 25 of CD-ROM drive 2 of the present invention is that a plurality of cantilevers 252 are around central portion 251 (the outer rim R of clamping piece structure 25 is surrounded with a plurality of breach C in other words), therefore, when CD-ROM drive 2 runnings, if be subjected to the external force F collision shown in Fig. 2 D right side arrow suddenly, then clamping piece structure 25 only has several cantilevers 252 because of the stressed distortion that produces a little, cantilever 252 shown in Fig. 2 D upper left side, the cantilever 252 meeting reinstatements promptly of those distortion afterwards make clamping piece structure 25 be able to clamping constantly and fixed light disc D.In other words, CD-ROM drive 2 of the present invention is when being subjected to external impacts, because the design of cantilever 252 (or breach C), so clamping piece structure 25 only can produce local distortion, can't as existing general and with upper shell 11 disengagings.
In sum,, can avoid the disengaging of clamping piece structure when CD-ROM drive is collided, and reach the clamping and the location of discs, and then improve the stability that CD-ROM drive uses by disclosed CD-ROM drive of the present invention and clamping piece structure thereof.
Though disclosed the present invention in conjunction with above preferred embodiment; yet it is not in order to limit the present invention; anyly be familiar with this operator; without departing from the spirit and scope of the present invention; still can do some change and retouching, thus protection scope of the present invention should with enclose claim was defined is as the criterion.
