Field of the Invention The present invention relates to an optical disk drive device, particularly to a shock absorbing device in which an optical disk drive can perform normal reading and writing under the vibration of a high-gravity acceleration. [Prior Art]
进年來，隨著可攜式電子產品的盛行，光碟機廣泛被 應用在筆記型電腦、隨身播放機及車用音響等產品上。然 而光碟機係以光學讀取頭從相對轉動的光碟片，讀寫細& 的資料記號，對震動相當敏感’些微的震動都會影響光碟 機讀寫的精性。 如圖1所示，為一習知光碟機的減震裝置10。實際上，因習 知光碟機11的機芯12，承載著轉動光碟片13的主軸馬達14及 光學讀取頭15等精密重要的零件，為了減少機芯12震動， 2碟機11内部於機芯12的四周，原就設有數個避震用膠環16 ’ ，芯f gi定在膠環16的外側，膠環16則以中心孔固定於光碟機 震動不致傳至機芯12，以免影響光碟機u讀寫的正確性。In the past years, with the prevalence of portable electronic products, optical disc players have been widely used in notebook computers, portable players, and car audio products. However, the optical disc drive is optically read from a relatively rotating optical disc, and reads and writes fine & data marks, which are quite sensitive to vibrations. A slight vibration affects the precision of the optical disc reading and writing. As shown in FIG. 1, it is a conventional shock absorbing device 10 of an optical disk drive. In fact, since the movement 12 of the optical disc drive 11 carries the precise and important parts such as the spindle motor 14 and the optical pickup 15 that rotate the optical disc 13, in order to reduce the vibration of the movement 12, the inside of the disc 11 is in the movement. Around the 12, there are several shock-absorbing rubber rings 16 ', the core f gi is fixed on the outer side of the rubber ring 16, and the rubber ring 16 is fixed to the optical disk machine with the central hole and the vibration is not transmitted to the movement 12, so as not to affect the optical disk. The correctness of machine u reading and writing.

Next, the front end surface of the optical disk drive 3 is covered, and the front shock absorbing portion 21 is formed in a corner shape. In addition, in the upper corners of the two front end corners of the optical disc drive 30, that is, opposite to the upper surface, the front end surface, and the side of the optical disc drive 30, the front shock absorbing portion 21 is provided with a plurality of cushions, that is, opposite to the optical disc drive 30. An upper cushion 215 is attached to the upper surface, and a front cushion 216 is adhered to the front end surface of the optical disc drive 30, and a side cushion 217 is attached to the side of the optical disc drive 30. The thickness of the cushions is less than The gap 23 maintains a small gap d between the cushions and the surface of the optical machine 30 (please refer to FIG. 4). The cushions may be made of an elastomer such as sponge or rubber. The rear damper portion 22 is also in the shape of a long slab, and the structure is identical to the front damper portion 21. Both end portions 221 of the rear damper portion 22 are flush with the fixed base 31, and each has a fixing hole 222. The intermediate portion 223 is shaped as a function of the shape of the rear end edge of the optical disk drive 30 with an appropriate gap 23 therebetween. At a side of the optical disc drive 30, a small rear guard piece 224 is extended rearwardly according to the height of the optical disc drive 30, along the rear end surface of the optical disc drive 30, and spaced apart by a suitable gap 23, without affecting the normal operation of the optical disc drive 30. Under the operation, the rear end surface of the optical disk drive 30 is covered, and the rear shock absorbing portion 22 is formed into a corner shape. In addition, in the upper corners of the two rear end corners of the optical disc drive 30, that is, opposite to the upper surface of the optical disc drive 30, the rear end surface, and the side connecting corners, the rear shock absorbing portion 22 is provided with a plurality of cushions. An upper cushion 225' is attached to the upper surface of the optical disc drive 30. A rear cushion (not shown) is attached to the rear end surface of the optical disc drive 30, and a side cushion 227 is attached to the side of the optical disc drive 30. . The thickness of the cushions is smaller than the gap 23' so that the cushions maintain a small gap d as well as the surface of the disc drive. When the optical disc damper device 20 of the present invention is used, it is under the optical disc drive 30, and a plurality of bottom dampers 24 are evenly spread on the bottom of the optical disc drive 30, which are generally laid on the four corners of the optical disc drive, so that the optical disc drive 30 is averaged by itself. Pressed on a number of bottom cushions 24. Further, before and after the front and rear ends of the optical disk drive 3, the front shock absorbing portion 21 and the rear shock absorbing portion 22 are respectively fitted with reference to FIG. 4, and FIG. 4 is a cross-sectional view formed by the AA line of the optical disk drive 30 of FIG. After the damper portion 21 and the rear damper portion 22 are placed on the optical disk drive 30, the damper device 20 is locked to the susceptor 31 by the fixing holes 211 and 221 . However, the shock absorbing pad on the front front damper portion 21 and the rear damper portion 22 maintains a proper gap d with the optical disk drive 30, that is, the damper device 2 〇 does not completely restrict the movement of the optical disk drive 30, but allows the optical disk drive 3 to Make a limited move. When the optical disk drive 30 reads and writes the optical disk 32, the internal mechanism of the optical disk drive 3 moves rapidly, and the vibration generated by the spindle motor 33 rotating the optical disk 32 is caused by the suspension rubber embedded between the movement 34 and the optical disk drive 30. The ring 35 absorbs, and some vibrations are transmitted to the optical disc drive 3〇. Since the weight of the optical disc drive 3远 is much larger than the weight of the movement 34, the reset ratio is about 1〇: 〗, the damping device 2 is not completely Restricted rhyme 30 utilizes its own kinetic energy to absorb normality without transmitting vibration to the external structure. Vibrate, abnormally raise H-induced "30 shock absorption 塾" and subject to shock 塾 restraint, by reduction; d set = 30 vibration, and inhibit the optical 蹲 machine 3 〇 (4) 〗 〖 absorbing optical disc machine *, the present invention _ damper device 20 will cause the frequency of the optical drive 30 to occur, about _ ζ, far lower than the 8 130 Hz of the conventional optical disk drive, the re-acceleration (G value) After the phase, the gravity of the optical disk drive 30 is accelerated _H and the vibration of the machine 30 is reduced, and the optical drive 3 = causes the external structure to vibrate and stand. The reading and writing of the crane is not shocked, and the buffer of the shock absorber around the shock absorber 20 of the outer Qiuyi floor is shock-damped, and the external structure transmits the vibration to the optical disk drive 30, and the optical disk drive 30 reads and writes normally.

Fig. 6 is a view showing an optical disk drive damper device according to a second embodiment of the present invention. The basic structure of the optical disk drive damper device 20 is similar to that of the optical disk drive damper device 20 of the first embodiment. For simplification of description, the same reference numerals are used in the previous embodiment. The main difference of this embodiment is that the shock absorbing 41 of each part of the damper device 40 is in slight contact with the light t-machine 30. Although the damper device 40 directly bears the optical disk drive = 'the initial vibration of the transmission wheel to the external structure, but The damping device 40 is used to suppress the vibration of the light source 30 as soon as possible to improve the reliability of the optical disk drive. Similarly, the optical disk drive damping device of the second embodiment of the present invention can achieve the object and function of the present invention. .
