Description of the Invention: [Technical Field of the Invention] [0001] The present invention relates to an electronic device, and more particularly to an optical disk drive. [Prior Art] [0002] Optical discs are widely used in people's lives because of their large storage capacity and convenient storage, and optical disc players are widely used as an electronic device for playing optical discs. [0003] The conventional optical disk drive is usually a clamshell type, and the user can open the disc cover to engage the optical disc on the holding portion of the spindle motor on the optical disc drive. When the CD player starts running, the spindle motor begins to rotate so that the information on the disc can be completely read by the optical pickup. However, since the gap between the rotating shaft of the spindle motor of the optical disc drive and the disc cover is small, when the disc cover is slightly pressed, the disc cover rubs against the end portion of the rotating shaft. Since the spindle motor and the disc cover are made of a hard material, a friction between the disc cover and the end of the shaft is easy to make a sharp abnormal sound, which not only affects the user's appreciation of the disc, but also the friction is prolonged and easily damaged. The turning shaft in turn damages the entire spindle motor or damages the disc cover. SUMMARY OF THE INVENTION [0004] In view of the above, it is necessary to provide an optical disk drive such that the friction between the spindle motor and the disk cover is less likely to cause abnormal sound. [0005] A CD player includes a housing, a disc cover that is disposed on one side of the housing, and a spindle motor disposed in the housing, the spindle motor having a rotating shaft, the rotating shaft having a disc and the disc The opposite end of the cover. At the same time, the optical disc drive has a protection structure disposed between the end portion of the rotating shaft and the oppositely facing disc cover portion of the rotating shaft to avoid the spindle motor 099133165 Form No. A0101 Page 3 / Total The rotation of the 16 page 0992057969-0 201214424 causes the end of the shaft to rub against the disc cover to generate an abnormal sound. [0006] By providing a protective structure, during the use of the above-mentioned optical disk drive, the spindle motor does not rub against the disk cover to emit an abnormal sound. [0007] Referring to FIG. 1 and FIG. 2, FIG. 1 is a schematic view of a preferred embodiment of the present invention, in which the disc cover 30 is in an open state, and FIG. 2 is an exploded view of a preferred embodiment of the present invention. schematic diagram. The optical disc drive 10 includes a housing 20, a disc cover 30 pivotally connected to the side of the housing 20, a movement carrier 40 disposed in the housing 20, and an optical pickup 50 disposed on the movement carrier 40. With the spindle motor 60 [0008] The housing 20 has an upper housing 22 and a lower housing 24. The upper casing 22 has a first side surface 24, and a disk receiving area 220 is recessed downwardly for receiving the optical disk. In addition, the upper casing 22 defines an irregular opening 222 in the optical disk receiving area 220. The lower casing 24 is disposed on the other side of the upper casing 22 opposite to the first side surface 224, and cooperates with the upper casing 22 to form an accommodation space. The disc cover 30 is pivotally connected to the first side 224 of the upper casing 22, covers the optical disc accommodating area 220, and is rotatable relative to the upper casing 22 to achieve an open or closed state. The disc cover 30 has a second side 32 adjacent to the upper housing and a convex portion 34 projecting from the second side 32. [0010] As shown in FIG. 3, the movement carrier 40 is substantially rectangular, and is fixed on the lower casing 24 and received in the accommodating space formed between the upper casing 22 and the lower casing 24 and partially exposed. In the opening 222 of the upper casing 22. Movement carrier 099133165 Form No. A0101 Page 4 / Total 16 pages 0992057969-0 201214424 〇[0011] The center of 40 _ has - the basic rectangular opening 5 〇 slidable: set in the open call to the disc ( Figure 2: square == move and read the record disc information. The spindle motor _ is placed on the first hole 222 and is exposed on the first side 224 of the upper casing 22 for carrying and driving «rotation. The spindle motor 60 has a rotatable rotating shaft (not shown) and a catching portion 64 for engaging the optical disc. The rotating shaft has an end portion 62 corresponding to the convex portion 34 on the disc cover, and the locking portion 64 is sleeved on The rotating shaft is displayed on the first side 224 of the rotating shaft at the end of the rotating shaft. When the user engages the optical disc on the holding (four), the disc cover 3〇' can be opened to make the light fine, so that the field The object_rotates to cooperate with the optical reading to match the information on the Weixian disk (8), since the end portion 62 of the shaft is exposed on the first side (10) of the upper casing 22, and between the first side 32 of the disc cover 30 The gap is small. Therefore, in the case where the upper casing 卩卩 is slightly depressed by the pressing, the contact portion 62 and the convex portion 34 are brought into contact with each other. When the spindle motor 60 is rotated, the end portion of the rotating shaft and the tenon portion 34 are rubbed together, and the abnormal sound not only affects the user's appreciation of the optical disc but also easily causes the end portion of the rotating shaft to be damaged by excessive friction. The optical disc drive of the present invention also has a protective structure 70. [0012] Please refer to FIG. 4 and FIG. 5, FIG. 4 is a cross-sectional view of a preferred embodiment of the present invention. The disc cover 30 is in a closed state, and FIG. 5 is an enlarged schematic view of FIG. 3tv. The protective structure 70 is used to make the optical disc drive 1 not emit sound due to the pressure of the disc cover 30 during use. 7〇 includes a groove 72 formed on the end portion 62 of the shaft and a column 74 disposed in the groove 72. The column 74 protrudes 099133165 Form No. A0101 Page 5 / Total 16 Page 0992057969-0 201214424 [0013] [0014 ] 099133165 For the turning end of the bracket 62 and corresponding to the disc. After the convex portion 34 on the main surface _ the first side 32 is in the recess 72, the (four) 74 is integrally molded by injecting τ 软 with a soft material such as resin. The housing 2 is cut into the latching portion 64 to cover the disc cover 30. The first side 224 of the CD-ROM is started, so that the column 74 corresponds to the convex portion 34. The end portion 62 and the column 1 body H spindle motor 6G drive the rotating shaft to rotate, and the rotating shaft rotates the bowl to rotate at the same time. At this time, even if the disc cover is pressed 30, hard = pressed to the cylinder 74 'the convex portion 34 and the cylinder 74 are not sharp due to softness. Conversely, since the cylinder (10) is formed of a rigid material and (4) 34 on the disc (four), Belongs to #, the phase friction between the two is the friction between the soft material and the rigid material, π A 4 ', which will produce a sharp abnormal sound. Further, the pressing force of the convex portion 34 based on the soft material convex portion 34 body 74 is deformed and partially covered and weakened by the friction between the convex portion 34 and the convex portion 34. In the game, i field..., 'In order to make the cylinder 74 less susceptible to wear, the cylinder 74 can be made of a softer material than the soft material used as the main component, such as ABS, although it is in this embodiment. The protective structure 70 includes the groove 72 and the body 74. However, the technical solution of the present invention is not limited thereto. In other embodiments, the protection structure 70 may also include only integrally formed with the rotating shaft and protrude from the end portion of the rotating shaft 62. Abutting column made of soft material. In addition, the body 74 is not limited to the formation of the cylinder 74 by infusion of a soft material into the recess 72. In other embodiments, the body 74 can be formed in other ways. For example, the column 7 is also formed by covering a layer of a soft material such as a resin layer on a common connecting post. Or, the protective structure form number Λ〇1〇ι page 6 / total I6 stomach 0992057969-0 201214424 70 can be formed by directly covering the end portion 62 of the shaft with a layer of soft material. [0015] [0020] [0020] It can be understood that although in the present embodiment, the protection structure is disposed on the end portion 62 of the shaft, the technical solution of the present invention is not limited to this. In other embodiments, the protective structure 70 can also be a layer of soft material overlying the raised portion 34; alternatively, the protective structure 70 can include two layers of soft material overlying the end portion 62 and the raised portion 34, respectively.
