Abstract
The utility model discloses a damping device for a large capacity double-disc hard disk. The damping device for the large capacity double-disc hard disk belongs to the damping device for a hard disk and comprises the hard disk, a support frame, steel wire rope shock absorbers, connecting plates and a silicon rubber shock pad. The support frame is U-shaped, the steel wire rope shock absorbers, the connecting plates and the silicon rubber shock pad are all arranged inside the U-shaped support frame, the silicon rubber shock pad is disposed on the upper portion of the U-shaped support frame, and the hard disk is arranged above the silicon rubber shock pad. The steel wire rope shock absorbers are arranged on two sides of the hard disk, one sides of the steel wire rope shock absorbers are fixed to the hard disk through the connecting plates and bolts, and the other sides of the steel wire rope shock absorbers are fixed to the side wall of the U-shaped support frame through the connecting bolts. Compared with the prior art, the damping device for the large capacity double-disc hard disk is capable of achieving the normal operation of the large capacity double-disc hard disk under the circumstances of vibration and shock, and has the advantages of being simple in structure, easy to carry out, high in economic benefit and the like.
Description
Technical field
The utility model relates to a kind of shock attenuation device of hard disk, the two dish hard disk shock-absorbing devices of specifically a kind of high capacity.
Background technology
Big capacity hard disk is in the applied more and more of ruggedized computer kind; Mostly big capacity hard disk inside is two dish structures at present, and like 1TSAS3.5 inch hard disk, magnetic head needed accurate tracking when data read; Susceptibility to vibratory impulse is strong; Under vibration environment, cause magnetic head tracking difficulty under the normal influence, thereby cause hard disk to quit work, make the The whole calculations machine cause deadlock because of dynamic excitation power.
The utility model content
The technical assignment of the utility model is to above weak point, and a kind of two dish hard disk shock-absorbing devices of a kind of high capacity that can realize the two dish hard disk operate as normal under the vibratory impulse environment of high capacity are provided.
The utility model solves the technical scheme that its technical matters adopted: comprise hard disk, support, steel rope damper, web joint, silicon rubber beam; Support is a U type support; Steel rope damper, web joint, silicon rubber beam all are arranged on U type internal stent; U type support top is provided with the silicon rubber beam, and silicon rubber beam top is provided with hard disk, and the hard disk both sides are provided with steel rope damper; On hard disk, the steel rope damper opposite side is fixed on the sidewall of U type support through attachment screw steel rope damper one side through web joint and screw retention.
During installation, two steel rope dampers keep free state about making.The wire rope damping with the steel wire strand of different structure stranded by specific around to processing with pitch, have bigger deflection.When support receives dynamic excitation and is passed to steel rope damper to vibration force; Dry friction between the steel wire strand of steel rope damper and form stronger damping, simultaneously, steel rope damper produces distortion under external force; Thereby absorb in a large number and consumed energy delivered; Make the impulsive force that is passed to hard disk within the scope that hard disk mechanism can bear, guarantee the normal tracking of magnetic head, play the effect of protection hard disk.
Rubber shock-absorbing pad is in the bottom of hard disk, and the steel rope damper amplitude causes the problem that hard disk and support bump against greatly when playing the prevention low frequency, and hard disk is played position-limiting action.
The starting material of the steel wire of steel rope damper and silicon rubber beam all have favorable elasticity, after external force reduces or cancels, can return to free state, thereby make steel rope damper and silicon rubber beam return to free state.
Support and steel rope damper are that the raw material silicon rubber salt fog resistance of stainless steel and silicon rubber beam is better, have high corrosion resistance and lasting serviceable life.
The two dish hard disk shock-absorbing devices of a kind of high capacity of the utility model are compared with prior art, and simple in structure, easy to implement, damping effect is obvious, has good economic benefits, thereby, have good value for applications.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Accompanying drawing 1 is the structural representation of the two dish hard disk shock-absorbing devices of a kind of high capacity;
Accompanying drawing 2 is the vertical view of Fig. 1.
Among the figure: 1, steel rope damper, 2, attachment screw, 3, web joint, 4, support, 5, the silicon rubber beam, 6, hard disk, 7, screw.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.
The two dish hard disk shock-absorbing devices of a kind of high capacity of the utility model; Its structure comprises hard disk 6, support 4, steel rope damper 1, web joint 3, silicon rubber beam 5; Support 4 is a U type support 4, and steel rope damper 1, web joint 3, silicon rubber beam 5 all are arranged on U type support 4 inside, and U type support 4 tops are provided with silicon rubber beam 5; Silicon rubber beam 5 tops are provided with hard disk 6; Hard disk 6 both sides are provided with steel rope damper 1, and steel rope damper 1 one sides are fixed on the hard disk 6 through web joint 3 and screw 7, and steel rope damper 1 opposite side is fixed on the sidewall of U type support 4 through attachment screw 2.
Two its processing and fabricatings of dish hard disk shock-absorbing device of a kind of high capacity of the utility model are very simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.
Except that the described technical characterictic of instructions, be the known technology of those skilled in the art.
