Embodiment
Embodiment 1
Fig. 1 to Fig. 2 B is the accompanying drawing according to embodiment 1 drafting of vibration-damped component of the present utility model.Fig. 1 is the structural representation of the utility model embodiment 1 vibration-damped component, and wherein, Fig. 1 is that the vibration-damped component of the utility model embodiment 1 is to place 20 of electronic equipment chassis 21 and this cabinet 21 data access arrangement, in order to reduce the suffered vibration of this data access arrangement 20.In the present embodiment, this electronic equipment is a computing machine, and this data access arrangement 20 is the hard disks that place these electronic equipment chassis 21 inside, and this data access arrangement 20 comprises casing and the body that is placed in this casing.But the utility model is not as limit, and this vibration-damped component 1 also can be used for other data access arrangement such as CD-ROM drive, and this electronic equipment also can be used for server or other electronic equipment.
As shown in Figure 1, this vibration-damped component 1 second vibration damping portion 12 of comprising fixed part 10, connecting the first vibration damping portion 11 of this fixed part 10 and connect this first vibration damping portion 11.
This fixed part 10 is a screw, pass this fixed part 10 by means of lock member 14 such as screw, this vibration-damped component 1 is fixed on the cabinet 21 of this electronic equipment, and contacts this data access arrangement 20 with the binding site 13 of this second vibration damping portion 12 by this first vibration damping portion 11.It should be noted that this vibration-damped component 1 also can be fixed on this data access arrangement 20 by this fixed part 10, and contact the cabinet 21 of this electronic equipment by means of this first vibration damping portion 11 with the binding site 13 of this second vibration damping portion 12.This vibration-damped component 1 is the shell fragment of being made by metal material.
This first vibration damping portion 11 is circular arc type with this second vibration damping portion 12, and has different arc radius respectively, therefore has different elasticity coefficient k1, k2, in order to reduce external vibration and the impact influence to data access device 20.Simultaneously, this second vibration damping portion 12 also can connect on-fixed portion 15 part of this fixed part 10 (promptly away from), and this on-fixed portion 15 is designed to linear and falls perigon angle.
In the present embodiment, this first vibration damping portion 11 is mainly used in and reduces the influence of external vibration to the hard disk serviceability.According to the hard disc of computer test result, the external vibration frequency that influences hard disk is more than the 100Hz.Be to suppress external vibration more than the 100Hz to the influence of hard disk, need, so the system that is made up of this first vibration damping portion 11 and this hard disk has specific natural frequency ω at the suitable elasticity coefficient k1 of this first vibration damping portion 11 designs.According to theory of oscillation, for suppressing dither, this natural frequency should be as far as possible little, and the quality of tentation data access device 20 is m, and the first vibration damping portion, 11 quality are ignored.Therefore, by formula
As can be known, quality m is fixedly the time, and for obtaining less natural frequency, elasticity coefficient k also should be less.Therefore, the elasticity coefficient k1 of this first vibration damping portion 11 should be made as less.
Although the above-mentioned first vibration damping portion 11 also can resist certain percussive action, the impact instantaneous as computer booting, but because the first vibration damping portion 11 has less elasticity coefficient, impulsive force one regularly, the required deflection of this first vibration damping portion 11 is bigger, and therefore, this second vibration damping portion 12 of the utility model setting is as buffering, avoid cabinet directly to impact hard disk, thereby improve the shock resistance effect of hard disk.By theory of oscillation as can be known, burst length one timing, the system that natural period T value is bigger helps buffering.By formula
As can be known, quality m is to obtain bigger natural period T fixedly the time, and elasticity coefficient k should be made as bigger.Therefore, the elasticity coefficient k2 of this second vibration damping portion 12 is bigger than the elasticity coefficient k1 of this first vibration damping portion 11, helps reaching the shock resistance effect.In the present embodiment, this first vibration damping portion 11 is identical materials with this second vibration damping portion 12, not being both of its elasticity coefficient reached by the size that changes radian, promptly change the arc radius of this first vibration damping portion 11 and this second vibration damping portion 12, can obtain to have the vibration-damped component 1 of different elasticity coefficient k.
Fig. 2 A and Fig. 2 B are respectively this electronic equipments 2 when being subjected to external vibration and impacting, the physical model synoptic diagram of this vibration-damped component 1.
Under the situation of bearing less vibration or impact, shown in Fig. 2 A,, compress the first vibration damping portion 11 of this vibration-damped component 1 when external high frequency vibration transfer during to the cabinet 21 of electronic equipment.Because the first vibration damping portion 11 has less elasticity coefficient k1, thereby makes the vibration insulating system that this vibration-damped component 1 is set have lower natural frequency, and preferable anti-dither performance is provided.
Under the situation of bearing bigger vibration or impact, shown in Fig. 2 B, can compress this first vibration damping portion 11 and this second vibration damping portion 12 simultaneously.Because the second vibration damping portion 12 has bigger elasticity coefficient, just compare with the first vibration damping portion 11, be subjected to same external force to do the time spent, the deflection of the second vibration damping portion 12 is less than the deflection of the first vibration damping portion 11, avoid because external impact causes this first vibration damping portion 11 greatly because distortion is excessive, make data access arrangement 20 directly contact cabinet 21, avoid the damage of data access arrangement 20.
Hence one can see that, because impacting is rapid moment motion, usually energy in the momentary action of impacting on equipment, because the inertia load on the equipment and cause the acting force that produces in the individual component thus and may surpass the equipment permissible value, cause device damage, so the utility model design is to provide buffering by the second vibration damping portion 12, working time of collision is prolonged, thereby make energy be able to slow release.
Therefore, vibration-damped component of the present utility model possesses variable elasticity coefficient, and when system was subjected to less vibration and impacts, this vibration-damped component provided less elasticity coefficient to obtain the effect of favorable damping, opposing impact; When impacting greatly, then can provide bigger elasticity coefficient, the effect that in fixing deformation space, provides favorable damping, opposing to impact along with deflection increases.
