Description
Technical field
The utility model relates to a kind of hard disk unit.
Background technology
Usually hard disk directly is fixed on the hard disk rack by four screws, and hard disk all is directly to be connected with hard disk rack and screw with hard disk and hard disk rack, and hard disk has directly been passed to cabinet with regard to shaking through hard disk rack and screw.Its shortcoming is along with the rotation speed of hard disk constantly speeds, and can produce bigger noise and vibrations when operation, and vibrations can be passed to cabinet, causes the resonance of cabinet.Simultaneously, cabinet and hard disk rack also will shake directly passes to hard disk, when hard disk in when work, outside vibrations cause losing of data especially easily even cause the damage of hard disk.
The utility model content
In view of this, need provide a kind of hard disk unit that reduces the hard disk vibrations.
A kind of hard disk unit comprises hard disk main body, hard disk rack, a plurality of securing member and a plurality of shock-absorbing ring.The hard disk main body is installed in the hard disk rack, and it is provided with a plurality of threaded holes.Hard disk rack comprises loam cake and lower cover, is covered with a plurality of through holes down.Described through hole is corresponding one by one with described threaded hole.Described securing member is fixed in the threaded hole of hard disk main body.Each securing member comprises threaded portion, pars intermedia and holding parts, and the diameter of described pars intermedia is greater than the diameter of threaded portion and holding parts.The threaded portion is contained in the threaded hole of hard disk main body, pars intermedia connecting thread portion and holding parts.Each shock-absorbing ring embeds in the through hole of lower cover, and it comprises central through hole.The holding parts of securing member is inserted in the central through hole.
Embed because of the shock-absorbing ring in the through hole of lower cover, and the holding parts of securing member is inserted in the central through hole of shock-absorbing ring, thereby direct contact and the hard disk main body contacts with the direct of lower cover of having avoided securing member and lower cover reduced the shock transfer between hard disk main body and securing member and the lower cover.

Embodiment
Fig. 1 is the three-dimensional exploded view of the hard disk unit 100 of the utility model embodiment.Hard disk unit 100 comprises hard disk main body 20, hard disk rack 30, foam 40, a plurality of securing member 50 and a plurality of shock-absorbing ring 60.
Hard disk main body 20 is contained in the hard disk rack 30, and its top is provided with a plurality of threaded holes 22.
Foam 40 is installed between described hard disk main body 20 and the loam cake 34, is used to reduce the shock transfer between hard disk main body 20 and the loam cake 34.
Please be simultaneously with reference to Fig. 2 and Fig. 3, securing member 50 is fixed in the threaded hole 22 of hard disk main body 20, with fixedly connected hard disk main body 20 and hard disk rack 30.Each securing member 50 comprises threaded portion 52, pars intermedia 54 and holding parts 56, and threaded portion 52 and holding parts 56 lay respectively at the two ends of pars intermedia 54.Pars intermedia 54 in the form of annular discs and fixedly connected threaded portion 52 and holding parts 56, its diameter is greater than the diameter of threaded portion 52 and holding parts 56.Threaded portion 52 is provided with screw thread with in the threaded hole 22 that is fixed in hard disk main body 20.The top of holding parts 56 is provided with groove 560, so that open and fastening described securing member 50.
Described shock-absorbing ring 60 is fixed between lower cover 32 and the hard disk main body 20, to reduce the shock transfer between hard disk main body 20 and the lower cover 32.Each shock-absorbing ring 60 comprises central through hole 62, resettlement section 64, contact site 66 and a plurality of protruding 68.Central through hole 62 runs through resettlement section 64 and contact site 66, and the slightly larger in diameter of central through hole 62 is in the diameter of the holding parts 56 of securing member 50.It is conical that contact site 66 is, and projection 68 is convexly set in the vertex of a cone of contact site 66, and resettlement section 64 is positioned at the bottom of contact site 66.Resettlement section 64 is cylindrical, and its diameter is less than the minimum diameter of contact site 66.The minimum diameter of contact site 66 slightly equals the diameter of the pars intermedia 54 of securing member 50, thereby can effectively utilize shock-absorbing ring 60.
Please refer to Fig. 4 to Fig. 6, during installation, hard disk main body 20 is contained in the hard disk rack 30.Foam 40 is installed between described hard disk main body 20 and the loam cake 34.The resettlement section 64 of shock-absorbing ring 60 embeds in the through hole 320 of lower cover 32.The threaded portion 52 of securing member 50 is locked in the threaded hole 22 of hard disk main body 20, and the holding parts 56 that makes securing member 50 is inserted in the central through hole 62 of shock-absorbing ring 60, thereby hard disk main body 20, hard disk rack 30, foam 40, securing member 50 and shock-absorbing ring 60 just are assembled into one.After the installation, the pars intermedia 54 of securing member 50 contacts with the projection 68 of shock-absorbing ring 60; The contact site 66 of shock-absorbing ring 60 is between the pars intermedia 54 and lower cover 32 of securing member 50.
Because of the resettlement section 64 of shock-absorbing ring 60 embeds in the through hole 320 of lower covers 32, and the holding parts 56 of securing member 50 is inserted in the central through hole 62 of shock-absorbing ring 60, thereby direct contact and hard disk main body 20 contacts with the direct of lower cover 32 of having avoided securing member 50 and lower cover 32 reduced the shock transfer between hard disk main body 20 and securing member 50 and the lower cover 32.
Because of the pars intermedia 54 of securing member 50 contacts with the projection 68 of shock-absorbing ring 60, reduced the contact area of shock-absorbing ring and securing member 50 on the damping direction, thus damping when helping damping initial stage damping vibration or high-frequency vibrations.
Because of the contact site 66 of shock-absorbing ring 60 is conical, thereby strengthened the shock-absorbing effect of shock-absorbing ring 60.
