Problems solved by technology
[0002] Today's vehicle-mounted electronic equipment has higher and higher requirements for storage capacity, so many media players use hard disks as storage, and hard disks have high requirements for shock resistance under vehicle conditions. On the bracket with elastic body, and then install the bracket on the outer shell, this structure is only in one direction of anti-seismic situation, the other direction of the anti-seismic situation cannot be controlled or the anti-seismic control force is not enough, the hard disk in this anti-seismic mechanism It is not really isolated from the vibration source, and it cannot alleviate the impact on the hard disk from all directions, especially for the instantaneous impact.

Embodiment Construction
[0012] Below in conjunction with accompanying drawing and specific embodiment, the present invention will be described in further detail: as figure 1 , figure 2 , Figure 7 , Figure 8 Shown, the present invention is made up of hard disk 1, top bracket 2, oil pressure elastic member 31, shockproof cover 32, stage clip 33, bottom bracket 4, extension spring 5.
[0013] Such as image 3 , 4 , wherein the oil pressure elastic member 31 is put into the inner ring on the upper part of the shockproof sleeve 32, which is concave-convex and the center is provided with a round hole for placing a thimble. , and snap into the hook 32a to form the buffer unit 3 .
[0014] Figure 5 , Figure 6 It is a structural embodiment of an oil pressure elastic member. The hydraulic elastic member 31 is a hollow cylinder with a closed top surface and a circular hole 34 on the other top surface. The hydraulic elastic member 31 is filled with silicone oil.
[0015] Put the hard disk 1 between...

The invention relates to an anti-shock mechanism for a suspended vehicle-mounted hard disk, which comprises a bottom supporting frame and a top supporting frame, the hard disk is fixed on the top supporting frame, oil buffer units are arranged around the hard disk-fixing position of the top supporting frame, round-headed propping pins are arranged at positions on the bottom supporting frame, which correspond to the oil buffer units of the top supporting frame, the round-headed propping pins are inserted into the oil buffer units to connect the bottom supporting frame with the top supporting frame, and moreover, the top supporting frame is also connected with the bottom supporting frame through tension springs. Since the hard disk is mounted in suspension and isolated from the shock source, the impact on the hard disk, which comes form each direction, can be effectively buffered.
Description
technical field [0001] The invention relates to an anti-seismic mechanism of an electronic product, in particular to an anti-seismic mechanism of a suspended vehicle hard disk. Background technique [0002] Today's vehicle-mounted electronic equipment has higher and higher requirements for storage capacity, so many media players use hard disks as storage, and hard disks have high requirements for shock resistance under vehicle conditions. On the bracket with elastic body, and then install the bracket on the outer shell, this kind of structure is only in one direction of anti-seismic situation, and the other direction of anti-seismic situation cannot be controlled or the anti-seismic control force is not enough. The hard disk in this anti-seismic mechanism It is not really isolated from the vibration source, and it cannot alleviate the impact on the hard disk from all directions, especially for the instantaneous impact. . Contents of the invention [0003] In order to sol...
