Abstract

This invention relates to a hard disk, which comprises a shell with a size-matched HD interface, a core indeed one small HD, an elastic separator set between the core and shell, and an interface adaptor to transfer the core interface into the one on shell. This invention solves the anti-shock and anti-impact problems well with better performance and lower cost.

Description

Hard disk

[technical field]

The present invention relates to mass-memory unit, particularly relate to be applicable to move or rugged surroundings in the hard disk that uses.

[background technology]

Along with the develop rapidly of digital processing, electronic technology, the application of memory device is increasingly extensive, and is also more and more higher to the requirement of its capacity.Usually the hard disks that adopt as memory device more in fixed equipment, and the various types of mobile memory cards of then many uses are as memory device in mobile environment.Though this is that traditional hard disk has higher requirement for environment for use, is applicable to the use of stablizing in the cleaning ambient, and is for example indoor because hard disk at capacity with have much advantage in price, is subjected to the restriction of read-write mode, its antidetonation and shock resistance are not high.Mobile memory card then has better portability and lower service condition requirement, but the bottleneck that its memory capacity, reading and writing data speed and the price of rapidly climbing sharply based on the increase of memory capacity still can't be crossed at present.

Therefore in more intense capacity transfer amount or read or write speed and volume not under the situation as major consideration, hard disk remains the preferred unit of storage.But reliability service in having the mobile environment of such application need, conventional hard is incompetent often.

For example, when using,, also can roughly guarantee the normal use of common hard disk if in the good place of road conditions such as city or high-grade highway as vehicle-mounted hard disks.If it is but on rugged road surfaces such as suburb, field, violent jolting will influence the reliability of reading and writing data, serious even may cause permanent lesion to hard disk.In addition, be subjected to the restriction of the volume and the strength of materials, the impact resistance of common hard disk is generally lower, but in moving use, collision is the factor that must consider, and for the fixedly conventional hard of specification standards is arranged, is difficult to by structural improvement anti-impact force is greatly improved.Also have at present and develop the novel hard disk that has better anti-seismic performance and impact resistance compared to common hard disk, but many main flows that are difficult to become popularization with complicated technology, high material cost, and its basic boom based on the conventional hard technology of maturation, can't fundamentally be accomplished substantial breakthrough all the time.

[summary of the invention]

The purpose of this invention is to provide a kind of hard disk that is different from existing hard disk seismic design thinking fully with high strength and the extensive compatible existing equipment interface of excellent anti shock stability while energy.

The technical scheme that realizes above-mentioned purpose is: a kind of hard disk comprises housing, dish core, elastomer isolators and interface breakout box; Has the hard-disk interface that is complementary with its size on the described housing; Described dish core is provided with elastomer isolators for being contained in the mini-hard disk in the housing between dish core and the described inner walls; Described interface breakout box is forwarded to interface on the described housing with the interface of described dish core.

Described elastomer isolators is filled or is looped around between dish core and the inner walls in the mode of all or part of parcel.

Described elastomer isolators is preferably the elasticity spacer ring that is enclosed within on the dish core, and the thickness of spacer ring makes its outer wall can be close to inner walls.

Described interface breakout box can adopt such structure: comprise flexible circuit board and switching circuit board; Described switching circuit board is connected with interface on the described housing; Described housing has the first separate spatial accommodation and second spatial accommodation, holds described dish core and switching circuit board respectively; Described flexible circuit board is connected to switching circuit board in second spatial accommodation with described dish core interface from first spatial accommodation.

Preferably, the overall dimensions of described housing are consistent with 3.5 inches hard disks, and described dish core is 2.5 inches or less than 2.5 inches hard disk.

The present invention adopts technique scheme, and beneficial technical effects is: adopt the housing with big hard disk size and interface that small harddisk is carried out the secondary encapsulation, solved the antidetonation and the shock proof problem of hard disk easily.Owing to have enough spaces, housing parts can have suitable thickness, even if therefore comparatively common material, for example aluminium alloy etc. also can reach outstanding intensity.And small harddisk is because structural characteristics, itself just has better anti-seismic performance than big hard disk, just existing equipment all only is equipped with the interface that connects big hard disk (3.5 inches hard disks of standard) mostly, small harddisk is placed in the firm housing by elastomeric isolation layer parcel, not only strengthened its anti-seismic performance greatly, and existing equipment has been had compatible widely.Compare with the existing high strength hard disk of same size, the present invention has more excellent performance and simpler structure and cheaper cost.

Below by embodiment also in conjunction with the accompanying drawings, the present invention is described in further detail.

[description of drawings]

Fig. 1 is a kind of structural representation of hard disk.

[embodiment]

A kind of hard disk as shown in Figure 1, comprises housing 1, dish core 2, as the elasticity spacer ring 3 and the interface breakout box of elastomer isolators.The overall dimensions of housing 1 are consistent with 3.5 inches hard disks, and inside has the first separate spatial accommodation A and the second spatial accommodation B, and housing 1 has and 3.5 inches hard-disk interface C that hard disk is identical.Dish core 2 is 2.5 inches hard disks, is contained among the first spatial accommodation A of housing 1.Elasticity spacer ring 3 is enclosed within on the dish core 2, and dish core 2 and inner walls are on every side isolated, and the thickness of spacer ring 3 makes its outer wall can be close to inner walls, with the relative fixed of holding tray core 2 positions.The interface breakout box comprises flexible circuit board 41 and switching circuit board 42; Switching circuit board 42 is contained among the second spatial accommodation B of housing 1, and is connected with interface C on the housing 1; The interface that flexible circuit board 41 will be coiled core 2 is connected to the switching circuit board 42 among the second spatial accommodation B from the first spatial accommodation A, the interface of dish core 2 promptly is relayed to the interface C on the housing 1 like this, and hard disk of the present invention just can be convenient to use on the equipment that has 3.5 inches hard-disk interfaces in a large number.

Elastomer isolators among the present invention can adopt rubber-like materials such as electrostatic prevention foam, electrostatic prevention plastic cement, concrete isolation method except above-mentioned the dish core on the cover spacer ring mode can also determine according to the characteristics and the actual needs of selected material, for example in inner walls highly suitable Elastic plastic-rubber projection etc. being set, all is optional mode as long as small harddisk and inner walls can be isolated and made small harddisk have relatively-stationary position.

In the above-described embodiments, adopt 2.5 inches hard disks as the dish core, 2 inches, 1.8 inches littler in fact dishes also can be selected, but because the too small meeting of disk body brings the obvious minimizing on the memory capacity and the increase of cost, therefore, cooperate 3.5 inches housing still more suitable with 2.5 inches dish core.
