Description

Technical Field

[0001] The invention relates to a screw-free hard disk support frame and a working method thereof, belonging to the technical field of storage hard disks. Background Art

[0002] The server is the core computer that serves all computers in the network system. It can provide disk and print services and other functions required by network users. It can also allow each client to share various resources in the network environment. From the perspective of chassis structure, servers can be divided into three types: tower servers, rack servers, and blade servers. Most of the current mainstream servers use rack structures. The servers in this article are all described using rack servers as examples.

[0003] As an important component of server configuration, users have increasingly higher requirements for the convenience of hard disk maintenance. In a rack-mounted storage server, multiple hard disks are usually placed in their respective hard disk racks, and one side of the hard disk rack has a backplane that is electrically connected to these hard disks by snapping. The traditional installation method is to lock the hard disk and the hard disk rack with multiple screws, and then insert the server chassis and snap the backplane together. Although this method can ensure the stability of the hard disk, it is less convenient to operate during daily maintenance or replacement. On the other hand, due to the large number of hard disks loaded on the server, the hard disk will generate superimposed vibrations in the hard disk rack after it is turned on, and the hard disk rack is usually made of metal materials that are not conducive to shock absorption, which will ultimately directly affect the life of the hard disk.
