Embodiment
Please refer to shown in Fig. 2,3,4,5.CD driver noise silencing clamping sheet mechanism of the present invention comprises a clamp circle disk 20, and clamp circle disk 20 has outer portion 21, middle ring portion 22 and the internal ring portion 23 that is connected, and outer portion 21 and middle ring portion 22 lay respectively at the top and the below of internal ring portion 23 peripheries.Internal ring portion 23 has a plurality of uniformly-spaced symmetrically arranged slotted eyes 24, and has a plurality of elastic arms uniformly-spaced symmetrically arranged in the slotted eye 24 25 that extend to respectively, and each elastic arm 25 has the male member 251 that extends downwards.The bottom of internal ring portion 23 has a plurality of holes 261 in conjunction with the first magnetic assembly, 26, the first magnetic assemblies 26, passes and extend the first magnetic assembly, 26 belows for each male member 251, shown in Fig. 3,4.
In CD-ROM drive, there is not disc, the first magnetic assembly 26 of clamp circle disk 20 is when magnetic force between the second magnetic assembly 31 of motor 30 attracts mutually, the male member 251 of elastic arm 25 is the top of contact motor 30 earlier, produces the effect of buffering, the sound of generation in the time of can significantly reducing clamp circle disk 20 and contact with motor 30.Because of the elastic force of magnetic force greater than elastic arm 25, so magnetic force can keep clamp circle disk 20 and motor 30 contacted states, as shown in Figure 3.But this moment, elastic arm 25 is toward the top bulging deformation of internal ring portions 23, and accumulates elastic force, magnetic and the suction between clamp circle disk 20 and the motor 30 is diminished.Because the relation that the suction between clamp circle disk 20 and the motor 30 diminishes because of the setting of elastic arm 25, the strength that clamp circle disk 20 and motor 30 are separated also can diminish relatively, as shown in Figure 5, therefore also can significantly reduce the sound that produces when clamp circle disk 20 is separated with motor 30.The above-mentioned first magnetic assembly 26, the second magnetic assembly 31 can be respectively corresponding ironware or magnet.
Clearly, CD-ROM drive is at the state of the state that disc is arranged compared with no disc, and the sound that clamping device is produced when separating with clamping is little a lot.Go into seriously its reason, discovery is the result who varies in size and caused because of magnetic force.And the size of magnetic force depends on the distance between ironware and magnet.Clamp distance during no disc is little, so magnetic force is big, opposite clamp distance when disc is arranged is bigger, so magnetic force is less relatively.When not having the disc state as can be known from the above analysis, the reason that the clash of clamping and detachment process is bigger mainly is to diminish caused because of the distance between ironware and magnet.
The difference of holding force when holding force was with no disc when the present invention broke through and disc to be arranged in the past, increasing by one on the clamp circle disk under no disc state, a deboost except magnetic force, allow whole holding force, just magnetic force deducts deboost and diminishes, when holding force diminishes, the problem of natural collision sound just can make moderate progress; Elasticity is many more and also allow the design of clamp circle disk external form after the design that adds deboost.
Please refer to shown in Figure 4.The end, omited in the supporting surface that originally limits the first magnetic assembly 26 and the second magnetic assembly, 31 spacings in male member 251 bottoms of elastic arm 25 of the present invention, when no clamping disc, male member 251 bottoms will contact motor 30 tops, but because magnetic force is greater than the cause of the elastic force of elastic arm 25, the supporting surface that limits the first magnetic assembly 26 and the second magnetic assembly, 31 spacings still withstands on the motor 30, but the sum total holding force has diminished under the effect because of elastic force, and this is the result that wishes of the present invention just.
Please refer to shown in Figure 6.When clamping disc 40, the adding of disc 40 thickness is risen clamp circle disk 20, the distance that the first magnetic assembly 26 and the second magnetic assembly are 31, get back to clamping disc 40 states of setting, this moment, elastic arm 25 was returned to not stress of nature, and such situation and other general design are identical.The present invention just when clamping disc not, clamp circle disk and motor combine with detachment process in, can significantly reduce the noise of generation, but not influence the advantage of normal intermediate plate function.
The above record, only for utilizing the embodiment of the technology of the present invention content, modification, variation that any insider uses the present invention to do all belong to the scope that the present invention advocates, and are not limited to the disclosed person of embodiment.
