Detailed ways

In order to make the above objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation modes of the present invention will be described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth to facilitate a thorough understanding of the present invention. However, the present utility model can be implemented in many other ways different from those described here. Those skilled in the art can make similar improvements without violating the connotation of the present utility model. Therefore, the present utility model is not limited to the specific embodiments disclosed below. limit.

As a storage medium, optical disks have many shortcomings such as small capacity, easy damage, large physical size, and the need for additional optical disk drives. They have been gradually replaced by U disks and mobile hard disks. Nowadays, optical discs are no longer used in general office settings, so many desktop computers no longer have optical disc drives as options. However, in order to take into account the needs of different users during the design and production of general-purpose computer cases, optical discs are still designed The location of the drive (referred to as the optical drive position), and is often designed to be two. Existing applications also include converting unused optical drive bays into storage drawers or USB interfaces and SD card readers. At the same time, the inventor also found that some places such as homes or offices choose to install automatic uninterruptible power supply systems because they are worried about power outages. However, in the existing technology, the power supply system of desktop computers does not integrate an energy storage device like a notebook computer. At the same time, the existing automatic uninterruptible power supply system is an external independent module. Users need to add the system separately between the computer power cord and the power socket, which makes the office environment messy and brings certain safety risks.

In order to solve the above problems, this utility model provides an automatic uninterruptible power supply system for the optical drive position of a desktop computer chassis.
