Embodiment
Hard disk shock-absorbing structure of the present utility model comprises hard disk bracket, fixed support, also comprise a plurality of be used to connect hard disk bracket and support bracket fastened rubber-like beams, introduce hard disk shock-absorbing structure of the present utility model in detail below in conjunction with specific embodiment and how to realize.
As shown in Figure 1 and Figure 4, hard disk shock-absorbing structure first embodiment of the present utility model is the shock-damping structure of 2.5 cun hard disks, comprises hard disk bracket 20, fixed support 30 and a plurality of rubber-like beam 40 that is used to connect hard disk bracket 20 and fixed support 30.Hard disk 10 by screw retention on hard disk bracket 20.Referring to Fig. 2, Fig. 3 a and 3b, in the present embodiment, beam 40 two ends have the annular groove 41 that extends along circumferentially, have the beam fixed orifice 21 and 31 suitable on hard disk bracket 20 and the fixed support 30 with annular groove 41, when installing, annular groove 41 is stuck in beam fixed orifice 21 and 31, and realization beam 40 is connected with hard disk bracket 20 and fixed support 30.For the ease of beam 40 is installed, promptly be convenient to beam 40 two ends are filled in beam fixed orifice 21 and 31, beam 40 has the through hole 43 that runs through its two ends, the existence of this through hole 43 has to enterolithic space when making beam 40 stress deformations, make easier the filling in beam fixed orifice 21 and 31 in two ends of beam 40, in order to make beam 40 have better damping effect, the shape that the middle part 42 of beam 40 is designed to outwards heave, this shape can be a cydariform, spherical, elliposoidal or other shapes, this shape is in conjunction with through hole 43, make beam have better damping effect, beam 40 is an elastic material, can be along through hole 43 axial and radial direction distortion, to slow down vibration from all directions, this beam 40 relies on its special structure and material to come damping, has alleviated the impulsive force that material is subjected to, and has prolonged the serviceable life of beam.
Referring to Fig. 1 and Fig. 2, in the present embodiment, in order to make the beam 40 easier hard disk brackets 20 of packing into, hard disk bracket 20 is provided with beam mounting hole 22, the diameter of this beam mounting hole 22 is greater than the diameter of beam fixed orifice 21, this beam mounting hole 22 and beam fixed orifice 21 are connected, during installation, one end of beam 40 is filled in beam mounting hole 22 earlier, slip in the beam fixed orifice 21 by beam mounting hole 22 under external force then, the existence of this beam mounting hole 22 also helps increasing the convection channel of hard disk surrounding air, helps the heat radiation of hard disk.Do not adopt identical beam mounting hole on the fixed support 30, this is because if all offer the beam mounting hole on hard disk bracket 20 and the fixed support 30, beam 40 can not get effectively fixing easily.Beam is 12 in the present embodiment, also can select the then number of beam as required in the practical application, and the number of beam is preferably even number.
In the present embodiment, beam 40 is the silica gel material, also can be rubber or other resilient materials in actual applications.
As described in Figure 5, second embodiment of the present utility model is the shock-damping structure of 3.5 cun hard disks, comprise hard disk bracket 20, fixed support 30 and the beam 50 that connects hard disk bracket 20 and fixed support 30, the structure of the beam 50 in the present embodiment is different from the structure of beam among first embodiment.Referring to Fig. 6 a-Fig. 6 d, in the present embodiment, the two ends of beam 50 are provided with threaded hole 51, beam 50 is connected and fixed by screw 60 and hard disk bracket 20 and fixed support 30, screw 60 is suitable with screw 51, is respectively arranged with on hard disk bracket 20 and the fixed support 30 to be used for the hole 24 and 32 that screw passes through.In order to have better damping effect, the middle part of beam 50 outwards heaves 53, and have a through hole 52 at the middle part of beam 50, this through hole 52 makes beam being subjected to external force to have more deformation space as the time spent, makes beam all have good damping effect in all directions.
In this example, good in order to make Hard disk heat radiation, also have the louvre 23 that is used to increase air convection channel on the hard disk bracket 20.In some occasion, for example fixed support and other devices form the cavity of a sealing, hard disk and hard disk bracket are positioned at the sealing cavity, in this case, in order to improve the heat radiation of hard disk, can louvre be set also on fixed support, the inside and outside air of cavity can be circulated to promote the heat radiation of hard disk.
In this example, the material of beam is the rubber material, also can be silica gel or other resilient materials in actual applications.The number of the beam in this example is four, also can according to the actual conditions choosing then be preferably even number in the practical application, and beam should be distributed on the hard disk bracket near peripheral position as far as possible.
Hard disk shock-absorbing structure of the present utility model is not limited to the hard disk specification among above-mentioned two embodiment, and the structure of the beam among two embodiment and hard disk bracket and support bracket fastened structure can be exchanged.
In sum; in hard disk shock-absorbing structure of the present utility model; adopt the rubber-like beam to connect between hard disk bracket and the fixed support; can effectively reduce the vibration transfer between hard disk bracket and the fixed support; the vibration of hard disk and cabinet is kept apart; prevent to produce resonance between hard disk and the cabinet, reduce noise, protection hard disc data safety.
In conjunction with the accompanying drawings embodiment of the present utility model is described above; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment only is schematic; rather than it is restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away under the scope situation that the utility model aim and claim protect, also can make a lot of forms, these all belong within the protection of the present utility model.
