Abstract

The utility model relates to a shock-absorbing device for protecting a hard disc from breaking under outside impaction, in particular to a hard disc shock-absorbing device which is applied to vehicle-mounted memory and backup products. The hard disc shock-absorbing device has the advantages of fewer assembly components, simple structure and greatly simplified change steps of a hard disc. The heat radiation of the hard disc is ensured by a ventilation hole of a shock pad and through holes of an upper bracket and a lower bracket; a use shock-absorbing range of the shock-absorbing device is greatly expanded due to adjustable thickness of the shock pad, the strength coefficient of a spring, and the use amount; due to the action forces of the upper bracket and the lower bracket on the shock pad, the vibration amplitude of the hard disc is relatively reduced in a voltage increasing state, the impaction resistance of the hard disc under a severe environment is greatly improved, and the problem of shock absorption of the hard disc in the vehicle-mounted memory and backup products is solved. The hard disc shock- adsorbing device comprises the upper support, the lower support, the shock pad and the spring.

In the vehicular applications environment; The vibration of (particularly under abominable road conditions condition) hard disk is very big under the driving states; Be easy to damage; Cause loss of data and damage, cause irreparable damage to the user, how carrying out vehicle-mounted storage becomes storage and back up the active demand that product is used in vehicle environment with the hard disk shock-absorbing that backs up product.The shock-damping structure complex design of existing vehicle-mounted hard disks, volume is bigger, is installed on dismounting hard disk complicated steps, does not take into full account the heat radiation of hard disk.

Summary of the invention

The utility model is realized the damping of hard disk in vehicle-mounted storage and the backup product through a kind of beam and the dual damping of spring and device for convenience detach and that hard disk is installed, satisfies the shock attenuation needs of hard disk under the vehicle environment.

The said a kind of hard disk shock-absorbing device of the utility model comprises lower carriage, upper bracket, beam, spring.

The annexation of above-mentioned ingredient is:

Spring is installed in the blind hole of beam upper and lower surfaces; Beam is placed in the lower carriage; Hard disk is installed in the front and back through hole of beam; Upper bracket is placed into above the beam, and guarantees scrunching of upper bracket two side curved all in two sidewalls of lower carriage; To go up lower carriage through screw is fixed together; Through screw hard disk is fixed on the lower carriage.

Beneficial effect

The device building block that the utility model proposes is less, simple in structure, has simplified the replacing step of hard disk greatly; The air vent of beam reaches the heat radiation that the through hole of going up lower carriage has guaranteed hard disk; Adjustable beam thickness and spring strength coefficient, usage quantity have been expanded the use damping scope of this shock attenuation device greatly; Last lower carriage makes the hard disk basis under a kind of pressurized state to the acting force of beam, has reduced the vibration amplitude of hard disk relatively, has improved the impact resistance of hard disk under rugged surroundings greatly, has solved vehicle-mounted storage and the hard disk shock-absorbing problem that backs up in the product.

Embodiment

Below in conjunction with accompanying drawing the preferred embodiment of the utility model is done further explain.

Embodiment

A kind of disk shock-damping structure, it forms like Fig. 1 extremely shown in Figure 8, comprises 1-beam, 2-lower carriage, 3-upper bracket, 5-spring.

Wherein, beam 1 comprises a plurality of blind hole 6, a plurality of first manhole 7 (heat dissipation ventilation hole), a plurality of second manhole 8, one first rectangular through holes 9, a plurality of first Long Circle through hole 10;

Lower carriage 2 comprises a plurality of second Long Circle through holes 11, four the 3rd manholes 12, three second rectangular through holes 13, the first bending wall 14;

Upper bracket 3 comprise four round thread holes 15, three the 3rd rectangular through holes 16, two scrunch curved 17, the second bending wall 18.

Annexation between the above-mentioned ingredient is:

Spring 5 is fixed in the blind hole 6 of beam 1, and is as shown in Figure 4.

Beam 1 is fixed in lower carriage 2 and the upper bracket 3.During installation; Earlier beam 1 is pushed into the first bending wall 13 along lower carriage 2 inwalls; With the upper wall of upper bracket 3 applying beams 1 and sidewall (and the both sides that guarantee upper bracket 3 scrunch the madial wall of curved 17 lateral wall applying lower carriages 2) from the front of beam 1 to pusher, until the inwall and beam 1 applying of the second bending wall 18 of upper bracket 3.
