Abstract
The utility model discloses a vehicle hard disk video recorder shock-absorber which comprises a hard disk rack and a hard disk box; the bottom of the hard disk rack is connected with the hard disk box through at least one cylindrical steel wire rope shock-absorber. In different hard disk and anti-shock environment, the vehicle hard disk video recorder shock-absorber changes the damping and elastic coefficient by increasing or decreasing the number of single-stage cylindrical steel wire rope shock-absorber and adjusting the length of a steel wire rope, so that the cylindrical steel wire rope shock-absorber can flexibly adapt to the requirements of all working environment. The vehicle hard disk video recorder shock-absorber is mainly used in vehicle hard disk video recorders, and has the advantages of simple structure, low cost, simple installation and easy maintenance.
Description
Technical field
The utility model belongs to vehicle-mounted hard disks video recorder field, relates in particular to a kind of vehicle-mounted hard disks video recorder vibroshock.
Background technology
Vehicle-mounted hard disks video recorder has on the market adopted single-stage now, two-stage or three grades of vibroshocks, single-stage vibroshock damping poor reliability, multistage vibroshock takes up room greatly, and the damping element of employing is oil sealing damping pad pin and spring, rubber feet, rectangular spiral helicine wire rope.Oil sealing damping pad pin and spring, rubber feet damping element take up room bigger, run into that different vibration environments can't adjust or difficult the adjustment, and device is complicated, difficulty is installed, and easily aging, the life-span is short, be not suitable for rugged environment.Rectangular spiral helicine steel rope damper occupation space is also bigger, and the quantity of grip block is many up and down, and the clamped wire rope cannot say for sure that card clamps, if wire rope occurring moves, maintenance is difficult.
At present, a kind of hard disk shock-absorbing device is also arranged, comprise the hard disk fixed mount, the both sides that the hard disk fixed mount is relative are connected with auxiliary frame by damping, this structure is because its damping is arranged at hard disk fixed mount both sides, and the position that takes up space is also bigger, and must realize by auxiliary stand, also can't adjust running into different vibration environments, and wire rope also is difficult to guarantee to clamp.
The utility model content
The purpose of this utility model be to provide a kind of little, good reliability of taking up room, installation simple, safeguard easily, cost is low, and the vehicle-mounted hard disks video recorder vibroshock that is easy to adjust in different hard disks and vibration environment.
The technical scheme that the utility model is adopted for achieving the above object is: a kind of vehicle-mounted hard disks video recorder vibroshock is provided, and it is to be connected with hard-disk cartridge by at least one cylindricality steel rope damper in the bottom of hard disk rack.
Compared with prior art, the beneficial effects of the utility model are: for different hard disks and vibration environment, can pass through the quantity and adjustment length of steel wire rope of the cylindricality steel rope damper of increase or minimizing single-stage, change the damping and the elasticity coefficient of cylindricality steel rope damper, make the cylindricality steel rope damper can the various working environment needs of flexible adaptation, simultaneously, adopt the single-stage damping to reduce the damping progression of vehicle-mounted hard disks video recorder, increase shockproof reliability, and the cylindricality steel rope damper of single-stage helps laying with side of vehicle-mounted hard disks video recorder position and hangs, the application of reversal of the natural order of things.
The utility model is simple in structure, cost is low, installation is simple, maintenance is easy.

Fig. 2 is the cut-open view after the embodiment assembling among Fig. 1.
Fig. 3 is a cylindricality steel rope damper structural representation among Fig. 1.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As shown in Figure 1 and Figure 2, fixedly connected with hard-disk cartridge 4 inner chamber body by at least one cylindricality steel rope damper 3 in the bottom of hard disk rack 2, cylindricality steel rope damper 3 is fixed in the bottom and hard-disk cartridge 4 cavitys of hard disk rack 2 by securing member (screw), and hard disk 1 is fixed on the hard disk rack 2 by securing member (screw).Like this, just can make to form an elasticity between hard disk rack 2 bottoms and the hard-disk cartridge 4 and be connected, realize to hard disk rack 2 and the shock-absorbing function that is loaded on the interior hard disk 1 of described hard disk rack 2, without any need for other auxiliary parts, and owing to be arranged at the bottom of hard disk rack 2, its occupied space is very little.
As shown in Figure 3, described cylindricality steel rope damper 3 comprises single or single above wire rope and the fixed head that is used for fixing described wire rope, the utility model illustrated embodiment adopts single wire rope 32 and four fixed heads to assemble, described single wire rope 32 joins end to end, paired and symmetrically arranged fixed head 311 is fastened mutually with fixed head 312 and constitutes the first grip block 31A, fixed head 313 fastens and the fixing second grip block 31B of formation mutually with fixed head 314, described single wire rope is fixed between the plate body of two grip blocks, two grip block 31A, 31B is according to the needs of its installation and location 90 degree that stagger mutually, can make and have certain tolerant space between the two, described grip block 31A, grip block 31B is fixedlyed connected by securing member with hard-disk cartridge 4 inner chamber body with hard disk rack 2 respectively.Because wire rope 32 has certain elasticity when having certain rigid and bending, when vehicle-mounted hard disks video recorder vibroshock is subjected to external shock in vehicle-mounted video recorder box, cylindricality steel rope damper 3 plays shockproof mitigation by wire rope to suffered external force, and cylindricality steel rope damper 3 can be realized shockproof to hard disk of four direction up and down, for different hard disks and external shock environment, the quantity and the length of adjusting wire rope 32 of the cylindricality steel rope damper 3 by increasing or reduce single-stage, change the damping and the elasticity coefficient of cylindricality steel rope damper 3, make the cylindricality steel rope damper 3 can the various working environment needs of flexible adaptation, adopt the single-stage damping to reduce the damping progression of vehicle-mounted hard disks video recorder, increase shockproof reliability, and the cylindricality steel rope damper 3 of single-stage helps laying with side of vehicle-mounted hard disks video recorder position and hangs, the application of reversal of the natural order of things.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
