Abstract

The utility model relates to an embedded PC hard disk shockproof device, in particular to the fixed shockproof device preinstalled on the hard disk base and then jointed with the preinstalled circuit wafer. The shockproof device comprises a plurality of piercing shrapnels, and a groove on the side positioning the buffer. Besides, the insulating sheet is arranged on the upper face of the shockproof device, whereas, on the lower face is arranged a shockproof mat. The screw junctor goes through the perforations of the shrapnels and gets locked on the preinstalled hard disk base, and then goes through the buffer in the shrapnel groove in the form of the lock units, and gets locked in the preinstalled circuit wafer which positions the buffer in between the preinstalled hard disk and the preinstalled circuit wafer. In this way, the compression and deformation are produced by the shockproof mat and the buffer via the shrapnel, and the high frequency and the low frequency shock in the axis X, axis Y, axis Z. is separated. Therefore, the life span of the installed hard disk and the correctness of the file storage is ensured. The utility model is of simple overall architecture, and saves space by assembling on the preinstalled circuit wafer independent of the hard disk frame, and making the hard disk working with the fine level precision.

Description

The hard disc shockproof device of embedded computer

Technical field

The utility model relates to a kind of hard disc shockproof device of embedded computer, especially refer to be incorporated into again on the preinstalled circuit plate in default hard disk bottom installing vibration abatement, shake to resist the high and low frequency that is produced on the preinstalled circuit plate, and improve the serviceable life of hard disk and the accuracy of access data.

Background technology

The shockproof structure overwhelming majority of existing hard disk all is to accommodate hard disk and the shockproof member of arranging in pairs or groups is done a protection with hard disk rack (being framework); and shockproof member is to be locked in the hard disk side mostly; can form so-called " overhung construction "; yet; when the shockproof member of this kind is locked in the hard disk side; need to consider whether hard disk keeps horizontality; if the left side of hard disk; right both sides produce high; during low head (the long-time tiltedly pendulum of hard disk); make the hard disk in reading at a high speed shorten serviceable life easily; and the employed member of the existing shockproof structure of this kind is various; the assembling formality is also numerous and diverse; behind shockproof structure between consideration hard disk and the hard disk rack, also to note the shockproof effect between hard disk rack and casing more, make that the horizontality of the shockproof framework of whole hard disk is very accurate; so the existing shockproof structure of this kind still has very big improvement space.

And TW announces " the shockproof framework of the hard disk of industrial computing machine () " novel patent case No. 558031, TW application case number No. 91220341, as shown in Figure 5, it comprises a framework A, has a board A1, the corresponding side of this board A1 has side plate A2 respectively, and forms storage tank A3, and this hard drives B promptly is installed on storage tank A3; Interior elastic component C is fixed in storage tank A3 one side of the side plate A2 of this framework A, and elastic component C is provided with elastic C1 in this, and this elastic C1 touches to affixed this hard drives B; And outer elastic component D, its storage tank A3 that is fixed in the side plate A2 of this framework A tosses about, and this outer elastic component D is provided with elastic D1, and outer elastic component D is fixed in this industrial computer; So should have the shockproof framework of hard disk now, when reality is used, still have many defectives, as:

(1) its shockproof framework comprises framework A, interior elastic component C and outer elastic component D, and spare part quantity is many, the assembling degree of difficulty improves, and then causes assembling to be difficult for and consuming time taking a lot of work.

(2) hard drives B and interior elastic component C, outer elastic component D must be installed on the framework A, just can be mounted on the industrial computing machine again, not only volume range is big, and takies usage spaces extremely many on the industrial computer, causes the inconvenience of industrial computer internal electric facility planning.

(3) hard drives B reaches shockproof purpose by interior elastic component C, outer elastic component D in framework A, but it only has the shockproof effect of horizontal direction, for vertically to vibrations then be difficult for prevention, the still influence that might be given a shock.

Moreover TW announces " suspension type hard disk anti-vibration structure " novel patent M242827 number, TW application case number No. 92206170, as shown in Figure 6, it comprises: a base E, and hold and support this Winchester disk drive E1, the upper and lower of Winchester disk drive E1 then is provided with protection pad E11, protection pad E12 down respectively; Several Suspensions F, one end are fixed in this Winchester disk drive E1, and the other end protrudes from this Winchester disk drive E1 outside; And several shake avoiding bodies G, having elasticity, it has an affixed main body G1, and the end of this affixed main body G1 has a sleeve G2, and this sleeve G2 is sheathed on this Suspension F, and this affixed main body G1 is fixed in this base E; As above-mentioned structure, this Winchester disk drive E1 is via this several shake avoiding body G, be fixed in this base E, on base E, be coated with loam cake E2 again, and this base E can be fixed to this main frame shell, because the elastic buffer function that this several shake avoiding body G is brought into play makes this Winchester disk drive E1 obtain good shock-proof effect; But should have the hard disk anti-vibration structure now when using, still have many defectives, as:

(1) this Winchester disk drive E1 utilizes Suspension F and shake avoiding body G and is fixed in the receiving hole E31 of base E sidewall E3, obtain the shock-proof effect of horizontal direction for Winchester disk drive E1, but shake avoiding body G for vertically to vibrations promptly can't avoid, still make Winchester disk drive E1 that the possibility of the vibrations of producing is arranged.

(2) Winchester disk drive E1 is in upper and lower protection pad E11, the following protection pad E12 of being respectively equipped with, though can assist Winchester disk drive E1 to reach shock-proof effect, right also causing simultaneously coats Winchester disk drive E1, so that can't dispel the heat, might cause Winchester disk drive E1 because of overheated situation about damaging takes place, shorten the serviceable life of Winchester disk drive E1.

(3) Winchester disk drive E1 is installed in the base E, to reach shockproof effect by Suspension F, shake avoiding body G, the use member is many, assembling is difficult for and consuming time taking a lot of work, and is fixedly arranged on the circuit board, also take the very big space on the circuit board, influence circuit and electronic component layout on the circuit board.

So, how to solve the problem that has the Winchester disk drive shock-absorbing now, be the relevant manufacturer that is engaged in the industry and desire most ardently the direction place that research improves.

Summary of the invention
