AI Technical Summary

Problems solved by technology

However, the two mechanical components that are not in permanent contact will have a probability problem of whether they are properly meshed at the moment when they are separated again. 15, the problem of the toothed parts bumping against each other will cause the two mechanism components to squeeze each other, and cause the entire mechanism system to be stuck; moreover, after the known optical drive 1 completes the action of entering the disc, the second end of the second rack 132 132b meshes with the third gear 15, at this time, the second end 132b of the second rack 132 is easily broken due to the force exerted by the third gear 15
Therefore, a new design is urgently needed to solve the problems of the above-mentioned mechanism system being stuck and broken.

Abstract

The invention relates to a gear driving system used in disc reading / writing device. It comprises a first gear, a gear driving group and a driving board. The gear-driving group comprises a first gear and a third gear, and driving board has a first rack, a second rack and a notch. The notch is set on at one end of the driving board. The second rack is set close to the strip section surface of third rack and face to the third gear at the other side of the notch.

Description

technical field [0001] The present invention relates to a gear transmission system, and more particularly to a gear transmission system for an optical drive. Background technique [0002] Recently, due to the continuous improvement of computer peripherals and the continuous decline in their prices, optical drives have become a must-have electronic product for ordinary people. As shown in FIG. 1 , it is a schematic view of the appearance of a known optical disc reading and writing device (hereinafter referred to as optical drive 1 ). Its structure is shown in FIG. 2 . The known optical drive 1 can be further divided into a bottom 2 , a front cover 3 , a base plate 4 , a tray 5 and an upper cover 6 . [0003] FIG. 3 is an enlarged schematic view of the bottom 2 with a gear transmission system 10 . The gear transmission system 10 includes a gear transmission set 101 , a tray motor 11 , a first gear 12 and a transmission plate 13 . The gear transmission set 101 has a second g...
