Problems solved by technology

[0007] However, although the control structure of the memory metal wire simplifies the component parts of the hook and effectively drives the hook to disengage from the snap-in pin, the memory metal wire may still be damaged by the drop of the optical drive during reliability tests such as dropping. The excessive impact force of the drop caused the hook to pull the metal wire excessively and cause the memory metal wire to break, failing to pass the quality control test

Embodiment Construction

[0049] According to the above purpose, a preferred embodiment is hereby given together with drawings to illustrate the technical means used in the present invention and its effects.

[0050] In this embodiment, the locking mechanism is set on the tray, and the locking pin is set on the casing of the optical drive to illustrate the technical means and effects of the present invention. But the present invention is not limited to this kind of configuration, that is, the locking mechanism can be arranged on the casing of the optical drive, and the locking pin is arranged on the tray, as long as the locking mechanism and the locking pin can be effectively engaged with each other, the tray can be locked. Just put it in the CD-ROM drive.

[0051] Please refer to Figure 3, Figure 4 , Figure 3 and Figure 4 They are respectively a three-dimensional schematic view of the tray loading out casing of the optical drive according to an embodiment of the present invention and a structural ...

Abstract

The invention relates to a CD-ROM drive support locking device, which uses one swing arm and the memory metal with first and second lengths at different temperatures, to control the swing arm to push the locking device, to simplify the element and form space, and avoid cracking memory metal via impact force, when it is fallen.

Description

technical field [0001] The present invention relates to a locking device for an optical drive tray, in particular to a locking device for an optical drive tray that is driven by a memory metal and can effectively avoid excessive impact force caused by factors such as falling, which may cause the memory metal to break accidentally. Background technique [0002] At present, in the industry, the locking device used in the loading / unloading of the tray of the thin optical drive can be roughly divided into two driving modes, the solenoid valve and the DC motor, according to the driving components used. [0003] The above-mentioned locking device driven by the solenoid valve mainly fixes the hook and pin in a mutually locked state through the suction force generated by the solenoid valve, so that the tray is locked in the optical drive. However, when the optical drive is subjected to reliability tests such as dropping, it is easy for the impact force to be greater than the suction...
