A kind of hard-disk cartridge, be used to place hard disk, comprise: hard-disk cartridge top cover, hard-disk cartridge bottom and hard disk holder also comprise: at least two rubber-like vibroshocks that are coated on the hard disk both ends are provided with outstanding damping angle on each lateral surface of described vibroshock.
Preferably, described vibroshock is the cuboid cell body, wherein, cell body length is greater than the length of described hard disk, the width of cell body is greater than the thickness of hard disk, and be respectively arranged with a damping angle on the end face at two minor face places of this cell body, be provided with two damping angles respectively at least on three surfaces at place, long limit.
Preferably, the longitudinal profile at described damping angle is a triangle.
Preferably, described vibroshock is rubber absorbers.
Preferably, above-mentioned hard-disk cartridge also comprises: be arranged on first beam between the bottom surface of described vibroshock and described hard disk holder.
Preferably, above-mentioned hard-disk cartridge also comprises: be arranged on second beam between the medial surface of described vibroshock and described hard disk holder.
Preferably, above-mentioned hard-disk cartridge also comprises: be arranged at least two the 3rd beams on the described hard-disk cartridge top cover.
Preferably, described first beam, second beam, the 3rd beam are the damping cotton.
The technical scheme that is provided by above the embodiment of the present application as seen, described hard-disk cartridge has been set up at least two rubber-like vibroshocks that are coated on the hard disk both ends, each lateral surface of described vibroshock is provided with outstanding damping angle, be placed in the described hard disk holder after described hard disk and described vibroshock are fixing, at this moment, described outstanding damping angle contacts with described hard disk holder, because vibroshock has certain elasticity, can cushion the part vibration that is passed to hard disk by hard-disk cartridge, be reached for the purpose of hard disk shock-absorbing.And, because the contact area that the lateral surface of vibroshock is provided with between damping angle and the described hard disk holder is very little, strengthened the elasticity of vibroshock, further reduced the vibration that hard-disk cartridge passes to vibroshock, thereby this hard-disk cartridge can make the vibration frequency of hard disk and amplitude reduce greatly.
Embodiment
The hard-disk cartridge that the embodiment of the present application provides is applied in the vehicle-mounted monitoring equipment, by set up vibroshock in described hard-disk cartridge, passes to the vibration of hard disk with minimizing by hard-disk cartridge, thereby reduces the amplitude and the vibration frequency of hard disk.
In order to make those skilled in the art person understand technical scheme among the application better, below in conjunction with the accompanying drawing in the embodiment of the present application, technical scheme in the embodiment of the present application is clearly and completely described, obviously, described embodiment only is the application's part embodiment, rather than whole embodiment.Based on the embodiment among the application, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all should belong to the scope of the application's protection.
See also the perspective view of hard-disk cartridge shown in Figure 1, mainly comprise: hard-disk cartridge top cover (not shown), hard-disk cartridge bottom 1, hard disk holder 2, vibroshock 3, wherein:
Hard-disk cartridge holder 2 is fixed on the hard-disk cartridge bottom 1, is used to place hard disk, is placed in the described hard-disk cartridge holder 2 after vibroshock 3 and hard disk 4 fix, and hard-disk cartridge top cover and hard-disk cartridge bottom 1 fix.
At least two vibroshocks 3 are coated on hard disk 4 ends, and the lateral surface of vibroshock 3 is provided with outstanding damping angle, be vibroshock 3 with contacted of hard disk holder 2 contacted end faces and vibroshock and hard-disk cartridge top cover on be provided with the damping angle, six faces that guarantee hard disk comprise two damping angles at least, are keeping hard disk to reduce the vibration frequency and the amplitude of hard disk stably under the prerequisite.
Preferably, described vibroshock 3 can adopt resilient material to make, vibroshock in the present embodiment adopts a kind of special rubber to make, has certain rigidity, also has certain elasticity simultaneously, can guarantee that hard disk is in steady position, can cushion the vibration of hard disk holder again, thereby reduce the vibration of hard disk.
The hard-disk cartridge that the embodiment of the present application provides has been set up at least two rubber-like vibroshocks that are coated on the hard disk end, and the lateral surface of vibroshock is provided with outstanding damping angle.Because vibroshock has certain elasticity, can cushion the part vibration that is passed to hard disk by hard-disk cartridge, reach the purpose of damping.And, because the contact area that the lateral surface of vibroshock is provided with between damping angle and the described hard disk holder is very little, strengthened the elasticity of vibroshock, further reduced the vibration that hard-disk cartridge passes to vibroshock, thereby this hard-disk cartridge can make the vibration frequency of hard disk and amplitude reduce greatly.
Perspective view referring to a kind of vibroshock shown in Figure 2, described vibroshock 3 can be a cuboid cell body, and cell body length is greater than the length of hard disk, the width of cell body is greater than the thickness of hard disk, guarantee that hard disk can inject in the described cell body, the bottom of cell body is as vibroshock 3 and hard disk holder 2 contacted sides, and it is provided with at least two first damping angles 31, and this first damping angle 31 contacts with the medial surface of described hard disk holder 2; Two sides at the place, long limit of cell body are respectively as the end face and the bottom surface of vibroshock 3, and be respectively arranged with at least two damping angles on described end face and the bottom surface, wherein, the second damping angle 32 on the described end face contacts with the hard-disk cartridge top cover, and the 3rd damping angle 33 on the bottom surface contacts with the bottom surface of hard disk holder 2.An end face of cell body is provided with one the 4th damping angle 34, and another end face relative with the 4th damping angle 34 place end faces is provided with the 5th damping angle 35.
The longitudinal profile at above-mentioned damping angle is trapezoidal or triangle, and the surface of contact fixedly done of damping angle and hard disk is less like this, and the elasticity of vibroshock is bigger, can cushion the vibration that is passed to hard disk by hard-disk cartridge.
For saving material, can also on the bottom land with described cell body a rectangular opening be set, reduced the area of bottom land, can reduce the required material of vibroshock 3, reduce cost.
Preferably, between the first damping angle 31 of described vibroshock 3 and hard disk holder 2 medial surfaces, be provided with first beam 5; Be provided with the second beam (not shown) between the bottom surface of the 3rd damping angle 33 and hard disk holder 2; Described rectangular opening place at vibroshock 3 is provided with the 3rd beam 6; Be pasted with the 4th beam 7 on the described hard-disk cartridge top cover, described first beam 5, second beam, the 3rd beam 6, the 4th beam 7 all can adopt the damping cotton to make, further the buffering hard-disk cartridge is passed to the vibration of hard disk, reduces the vibration frequency and the Oscillation Amplitude of hard disk greatly.
Each embodiment in this instructions all adopts the mode of going forward one by one to describe, and identical similar part is mutually referring to getting final product between each embodiment, and each embodiment stresses all is difference with other embodiment.
The above only is the application's a embodiment; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the application's principle; can also make some improvements and modifications, these improvements and modifications also should be considered as the application's protection domain.
