Embodiment
As shown in Figure 1, hard disk shock-absorbing device 100 of the present utility model comprises loam cake 101, the lower cover 102 that constitutes hard-disk cartridge, and is arranged on hard disk 103, trimmer 104 and fixed mount 105 in the hard-disk cartridge.
As Fig. 1, Fig. 3, shown in Figure 5, left and right, the top of loam cake 101, back four sides sealing, bottom surface and front end face opening, and the both sides, bottom surface are provided with web joint 106, and web joint 106 is provided with screw 109a.Lower cover 102 is a tabular, which is provided with corresponding screw 109b.Screw passes screw 109a, the 109b on web joint 106, the lower cover 102, and loam cake 101, lower cover 102 are linked together, and constitutes hard-disk cartridge.Hard-disk cartridge is a rectangular parallelepiped, and its front end face opens wide, and is used to connect output line; Other five faces all seal.
With reference to Fig. 1 and Fig. 4, hard disk 103, trimmer 104 and fixed mount 105 threes link together, and are arranged on hard-disk cartridge inside.Trimmer 104 is connected hard disk 103 belows, by this center of gravity of hard disk 103 is adjusted to the center of hard-disk cartridge.In addition, trimmer 104 can strengthen the weight of the assembly of hard-disk cartridge inside, thereby improves the shock resistance of hard disk 103.Fixed mount 105 is L-shaped, comprises orthogonal two parts, and vertically part 105a is used for being connected indirectly with the loam cake 101 of hard-disk cartridge; And horizontal component 105b is used for being connected with trimmer 104, hard disk 103.On the horizontal component 105b of fixed mount 105, trimmer 104, be respectively arranged with screw 110a, 110b, in hard disk 103 bottoms, be provided with corresponding screw 110c, screw successively passes screw 110a, 110b, 110c, and the three is linked together.
In order to slow down the vibrations between hard-disk cartridge and the intraware, between hard-disk cartridge and intraware, be provided with a plurality of shock reducing structures 107.This shock reducing structure 107 is made by resilient material, for example silica gel.This silica gel material is in harmonious proportion according to certain ratio by bi-component silica gel and dilution and forms.According to the two kinds of silica gel compositions of bi-component silica gel and the difference of dilution three ratio, reconcile into the different silica gel material of hardness, be divided into two kinds in hard gel and soft silica gel.Correspondingly, the silica gel shock reducing structure of being made by hard and soft silica gel material is called hard gel shock reducing structure and soft silica gel shock reducing structure.
With reference to Fig. 2, each shock reducing structure 107 includes the shim-like part 107a at two ends and the center section 107b that heaves.This center section 107b can be cydariform, sphere, elliposoidal or the like.Shock reducing structure 107 is provided with the through hole 107c that runs through shim-like part 107a and center section 107b.The shim-like part 107a at two ends is used for passing corresponding fixed orifice, and shock reducing structure 107 is connected on the fixed orifice.Center section 107b and inner through hole 107c make the shock reducing structure 107 can be crooked, come from the vibrations of center section 107b side with buffering.Shock reducing structure 107 can stretch and shrink simultaneously, comes from the vibrations of the axis direction at shim-like part 107a two ends with buffering.Owing to rely on the structure and the material of shock reducing structure 107 to come damping, come damping with only relying on the material of material in the prior art, alleviated the impulsive force that material is subjected to, prolonged the serviceable life of shock reducing structure 107.
With reference to Fig. 1, on the end face and left and right sides sidewall of loam cake 101, on the lower cover 102 and on the fixed mount 105, be provided with a plurality of mounting holes 108 that are used to install shock reducing structure 107.Also can be provided for installing the mounting hole 108 of shock reducing structure 107 on the rear end face of loam cake 101.Consider that main low-frequency vibration (50Hz is following) from above-below direction, therefore will prevent that the soft silica gel shock reducing structure 107 of low-frequency vibration is arranged on the end face and lower cover 102 of loam cake 101, cushion low-frequency vibration in the mode of shrinking.And the shock reducing structure 107 of left and right directions not only plays cushioning effect, also play fixation, therefore the left and right sides sidewall of loam cake 101 and the shock reducing structure between the fixed mount 105 107 adopt the hard gel shock reducing structure, cushion the high-frequency vibration of all directions in the mode of bending, and cushion the high-frequency vibration of left and right directions in the mode that stretches and shrink.
The shim-like part 107a of a plurality of shock reducing structure 107 1 ends passes the mounting hole 108 on the end face of loam cake 101, and the shim-like part 107a that makes the center section 107b and the other end is towards lower cover 102.Other has the shim-like part 107a of a plurality of shock reducing structure 107 1 ends to pass mounting hole 108 on the lower cover 102, and the shim-like part 107a that makes the center section 107b and the other end is towards loam cake 101.
On the fixed mount 105, the shim-like part 107a of a plurality of shock reducing structure 107 1 ends passes the vertical part 105a of fixed mount 105, and the shim-like part 107a that makes the center section 107b and the other end is towards the left and right sides of loam cake 101 sidewall.Make the shim-like part 107a of this other end pass mounting hole on the left and right sides sidewall of loam cake 101 afterwards, the left and right sides sidewall of loam cake 101 and fixed mount 105 are linked together, and with the center section 107b space of shock reducing structure 107.
Next, loam cake 101 is inverted, and hard disk 103, trimmer 104 are inserted in the loam cake 101, make the corresponding screw alignment of hard disk 103, trimmer 104 and fixed mount 105, the three is coupled together with screw.Afterwards lower cover 102 is fixed on the loam cake 101, forms complete hard-disk cartridge.At this moment, three assemblies in the hard-disk cartridge: hard disk 103, trimmer 104, fixed mount 105 threes interconnect, and upper and lower upwards installs mutually by end face, the bottom surface of soft silica gel shock reducing structure 107 with hard-disk cartridge; Interconnect by the left and right sidewall of soft silica gel shock reducing structure 107 with hard-disk cartridge on the left and right directions, the three is unsettled to be arranged in the hard-disk cartridge.Therefore, both can Fixed disk 103, can cushion the external shock on all directions again.
Hard disk shock-absorbing device of the present utility model has been completely abolished being rigidly connected between hard disk and the hard-disk cartridge, to the impact from all directions, different frequency, all can play damping effect preferably.And, the special construction of shock reducing structure, the impact that vibration-absorptive material is subjected to is less, has prolonged the serviceable life of vibration-absorptive material.
