Embodiment
Below will clearly demonstrate spirit of the present invention with accompanying drawing and detailed description, have in the technical field under any and know that usually the knowledgeable is after understanding preferred embodiment of the present invention, when can be by the technology of teachings of the present invention, change and modification, it does not break away from spirit of the present invention and scope.
With reference to Fig. 2, it is the three-dimensional view that illustrates Shockproof structure of air reaction type hard disk 200 1 preferred embodiments of the present invention.Include in the Shockproof structure of air reaction type hard disk 200 upper side 212, downside 214, major opposing side 210, with groove 220.Groove 220 can be formed in upper side 212, downside 214 and the major opposing side 210 formed ㄇ shape structures.Hard disk 260 can be contained among the groove 220 of Shockproof structure of air reaction type hard disk 200.Shockproof structure of air reaction type hard disk 200 more includes air plenum array 230.Air plenum array 230 can be divided into major opposing side 210, upper side 212 and downside 214.Include a plurality of air plenums 232 and a plurality of ventholes 240 in the air plenum array 230, venthole 240 is respectively to should a plurality of air plenums 232, and venthole 240 can run through the one side of air plenum 232 contact hard disks 260.Wherein the sectional area of venthole 240 is the sectional area less than air plenum 232.
With reference to Fig. 3 A, Fig. 3 B, it is the partial schematic diagram that illustrates Shockproof structure of air reaction type hard disk 200 of the present invention.Be convenient explanation, this figure draws according to actual ratio, close chat earlier bright.In the present embodiment, the ratio of the width d of venthole 240 and the width L of air plenum 232 is between 1/10～1/5 (1/10th to 1/5th); The width d of the venthole 240 and height L of venthole 240 can be isometric or near isometric.Be noted that air plenum array 230 can only be single discharge chamber 232 and single venthole 240 also, look closely product demand and decide.
General state when state 300 is not impacted for illustrating system 250, system 250 can be a hard disk support bracket, hard disk support bracket can with major opposing side 210, upper side 212, contact with downside 214, in addition, system 250 can be a metalwork or a plastic parts.310 states that illustrate when system 250 is subjected to clashing into of state, when impact is sent to hard disk 260, Shockproof structure of air reaction type hard disk 200 between system 250 and hard disk 260 is pressurized therefore, air in the air plenum 232 flows to venthole 240 because of being subjected to powerful extruding, with the pressure in the balance air plenum 232.But because the sectional area of venthole 240 is less than the sectional area of air plenum 232, airflow can produce air resistance because of the reduction of runner during to venthole 240, Shockproof structure of air reaction type hard disk 200 promptly utilizes this air resistance, the external force that buffer system 250 transmits reaches the effect that cushions hard disk 260.
With reference to Fig. 4 A to Fig. 4 C, it is the air plenum 232 different embodiment cut-open views that illustrate Shockproof structure of air reaction type hard disk 200 of the present invention respectively.The material of Shockproof structure of air reaction type hard disk 200 preferably can be rubber, and among Fig. 4 A, the end that upper side 212 contacts with system 250 is an openend, and promptly air plenum 232 directly contacts with system 250.Among Fig. 4 B, the end that upper side 212 contacts with system 250 is a blind end, and promptly air plenum 232 does not directly contact with system 250, and upper side 212 can be one of the forming, and air plenum 232 is for being formed directly among the upper side 212.
Perhaps, as shown in Fig. 4 C, upper side 212 is an openend away from an end of hard disk 260,250 of systems have the projection 252 corresponding to openend, projection 252 can be coupled with the openend of upper side 212, Shockproof structure of air reaction type hard disk 200 is arranged between system 250 and the hard disk 260 external force that buffer system 250 transmits.The foregoing description is to be example with the air plenum 232 that is arranged in upper side 212, and the state of above-mentioned air plenum 232 is not limited to upper side 212, and it can be applied in the air plenum 232 that is arranged in major opposing side 210, downside 214 among Fig. 2 equally.
With reference to Fig. 5 A to Fig. 5 C, it is the synoptic diagram that illustrates the air plenum array 230 different embodiment of Shockproof structure of air reaction type hard disk 200 of the present invention respectively.A plurality of air plenums 232 in the air plenum array 230 have venthole 240, and wherein the sectional area of venthole 240 is preferably to be the sectional area less than air plenum 232.The cross sectional shape of air plenum 232 can be the rectangle among Fig. 5 A, the circle among Fig. 5 B, and the ellipse among Fig. 5 C perhaps, also can be polygon in other embodiments.
By the invention described above preferred embodiment as can be known, use the present invention and have following advantage.When system is subjected to external impacts, air in the air plenum of Shockproof structure of air reaction type hard disk can be compressed and flow to the less venthole of sectional area, thereby the generation air resistance, Shockproof structure of air reaction type hard disk just can be by these vibrations of air resistance buffering hard disk in system.This Shockproof structure of air reaction type hard disk is by the design of air plenum and venthole, the impact magnification when reduction system effectively is subjected to external force, and balance time is got back to by shortening system significantly.
Though disclosed the present invention in conjunction with an above preferred embodiment; yet it is not in order to limit the present invention; anyly be familiar with this operator; without departing from the spirit and scope of the present invention; can be used for a variety of modifications and variations, thus protection scope of the present invention should with enclose claim was defined is as the criterion.
