Vibration isolation structure of optical disk drive

Abstract

A vibration isolation structure for a CD drive includes a bottom, a neck and a top, and the neck is used to connect the bottom and the top. The bottom, the neck and the top have a through hole, and the through hole runs through the top surface of the top and the bottom surface of the bottom along a through center line. In any annular section of the neck whose normal direction is the direction extending through the central line, the annular section has a first extension line extending from the central line to the outer periphery of the annular section. A thick wall. The annular section has a second wall thickness on a second extension line extending from the central line to the outer periphery of the annular section, and the first wall thickness is greater than the second wall thickness.

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...

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
