HARD DISK BOX, HARD DISK UNIT, AND ELECTRONIC DEVICE

摘要

A hard disk box, comprising a housing (10), a fixing support (20), shock absorbers (30), and a lower cover (40); the outer sides of two opposite first side plates (22) of the fixing support (20) are respectively provided with one shock absorber (30); the fixing support (20) provided with a hard disk (101) is mounted in an inner cavity (12) of the housing (10); the two shock absorbers (30) are correspondingly fitted between the inner wall of the housing (10) and the outer walls of the first side plates (22); the lower cover (40) is mounted on an opening (11) of the housing (10). Said hard disk box, a hard disk unit (100) and an electronic device having said hard disk box, can protect the hard disk (101) in a small space, preventing the hard disk from being damaged due to working in a complex shock environment, and reduce the volume, facilitating installation in a narrow space. When an external shock energy is transmitted to the shock absorbers of the hard disk box, shock energy rapidly damps, so that the energy transmitted to the hard disk box is much smaller than the external energy, and the higher the frequency is, the more obvious the effect is, offering effective shock protection to the hard disk (101).
