1. Technical field
The disclosure generally relates to an external hard drive.
2. Description of the Related Art
Many external hard drives include a housing and a disk drive assembly received in the housing for storing data. Generally, the disk drive assembly is fixed in the housing with screws. However, if the housing suffers shock and impact, the disk drive assembly may be damaged.
Therefore, there is room for improvement within the art.
Many aspects of an exemplary external hard drive can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the exemplary external hard drive. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views. Wherever possible, the same reference numbers are used throughout the drawings to refer to the same or like elements of an embodiment.
The housing 10 includes four sidewalls 12 connected with each other and a bottom wall 14. The four sidewalls 12 are perpendicularly connected to the bottom wall 14. The four sidewalls 12 and the bottom wall 14 together define a receiving cavity 16. Each sidewall 12 includes an inner surface 121, and a buffer block 122 is located on the inner surface 121 of each sidewall 12. In this exemplary embodiment, there are four buffer blocks 122. The buffer blocks 122 are made from soft sponge-like material. A circuit board 40 is located on one of the four sidewalls 12, and the circuit board 40 is electronically connected to the disk drive assembly 20 through a plurality of wires 50. Also referring to

The second magnet 26 is located opposite to the first magnet 142. The plurality of guide posts 144 pass through the corresponding plurality of through holes 222. Because the second magnet 26 and the first magnet 142 repel each other there is space between the magnets 26, 142, and the disk drive assembly 20 is suspended over the first magnet 142. The buffer blocks 122 are around the disk drive assembly 20. The cover 30 is covered on the housing 10 to allow the cushion 32 to resist and compact the disk drive 24. The assembly process of the external hard drive 100 is completed.
The disk drive 24 is suspended in the housing 10, and thus protected if the housing 10 suffers shock and impact. The buffer blocks 122 and the cushion 32 can absorb impact forces on the housing. Therefore, the disk drive 24 is effectively protected.
It is to be understood, however, that even though numerous characteristics and advantages of the exemplary disclosure have been set forth in the foregoing description, together with details of the structure and function of the exemplary disclosure, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of exemplary disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
