Problems solved by technology

When the CD player 10 is placed vertically with the x direction as the gravity direction, the weight direction of the core 12 is the x direction, which is easy to cause figure 1 The deformation in the x-axis direction of the vibration isolation structure 13 of the optical disc drive in A causes the center of the disc 19 to shift downward D, and then the lower edge of the disc 19 occurs when the disc 19 is figure 1 When the spindle motor 12b of A rotates, it is easy to grind the tray 12c and the base 11
In addition, in order to isolate the external impact force, the vibration isolation structure 13 of the optical disc drive is usually designed to be very soft. When the optical disc drive 10 placed horizontally is subjected to a large external impact force, the disc 19 is easy to shake up and down, which increases the disc vibration invisibly. Opportunity of sheet 19 grinding to the bearing surface of pallet 19

Embodiment 1

[0063] refer to Figure 4A ~4B, Figure 4A It is an exploded perspective view showing a partial structure of an optical disc drive with an optical disc drive vibration isolation structure according to Embodiment 1 of the present invention, and FIG. 4B shows Figure 4A The exploded and enlarged perspective view of the vibration isolation structure of the movement and optical disk drive. exist Figure 4A In ~4B, the optical disc drive 40 includes a base 41, a core 42 and at least one optical disc drive vibration isolation structure 43, the optical disc drive vibration isolation structure 43 is arranged between the base 41 and the core 42, and the optical disc drive vibration isolation structure 43 has a through hole 43a. The base 41 has at least one set of fixing columns 44 for inserting into the through holes 43 a so that the vibration isolation structure 43 of the optical disk drive is fixed on the base 41 . In addition, the opening shape of the through hole 43 a correspon...

Embodiment 2

[0073] refer to Figures 7A-7B , Figure 7A It is an enlarged side view showing the vibration isolation structure of the optical disk drive according to the second embodiment of the present invention, Figure 7B means along Figure 7A The sectional view of the vibration isolation structure of the optical disk drive viewed by the sectional line 7B-7B'. exist Figures 7A-7B Among them, the optical disc drive vibration isolation structure 53 at least includes a bottom 53b, a neck 53c and a top 53d, the neck 53c connects the bottom 53b and the top 53d, and the bottom 53b, neck 53c and top 53d have a through hole 53a. The through hole 53 a penetrates the top surface of the top 53 d and the bottom surface of the bottom 53 b along a central line L1 , and the extending direction of the central line L1 is the z direction.

Abstract

A vibration isolation structure of a disk machine includes a bottom, a neck and a top, the neck is for connecting the bottom and the top, each part has a through hole passing through the top surface of the top and bottom surface of the bottom along a line through the center. A first wall-thickness and a second wall-thickness are set on the first and second extending lines extending from the line to the ring-like section peripheries and first one is greater than the second.

Description

technical field [0001] The present invention relates to a vibration isolation structure of an optical disc drive, and in particular to a vibration isolation structure for an optical disc drive which can effectively isolate external impact force when the optical disc drive is installed horizontally or vertically. Background technique [0002] In today's era of rapid technological development, with the popularity of pictures, music, movies and computer software, discs with high storage capacity have become important software carriers in modern people's daily life. Among them, discs can be further divided into CDs and DVDs. Their characteristics of large capacity, small size and safe storage of data are more popular and adopted by the public. In addition, the optical disc drive that can read CDs and DVDs has therefore become one of the basic equipment of personal computers. [0003] refer to figure 1 , figure 1 It is an exploded perspective view showing a conventional optica...
