Description

Hard disk shock absorber and mobile storage device

technical field

The utility model relates to a hard disk vibration damping device and a mobile storage device.

Background technique

Mobile hard disks are divided into mechanical hard disks and solid-state hard disks. Mobile hard disks are widely used in various mobile storage devices, such as notebook computers, car storage devices, and digital devices. Vibration and shock will have a huge negative impact on the read/write performance and service life of hard disks, especially mechanical hard disks. Therefore, a vibration damping device needs to be provided for the mobile hard disk to prevent external vibrations from being transmitted to the mobile hard disk.

The commonly used damping device is the rubber damping structure, which is divided into rubber pad type and rubber frame type:

Rubber pad type: a rubber pad is interposed between the bottom surface of the mobile hard disk and the placement surface of the device. The rubber pad type is low in cost and easy to install, but it cannot limit the horizontal direction of the mobile hard disk, and cannot damp the horizontal direction of the mobile hard disk. In addition, in some cases, the mobile hard disk may hit the inner wall of the device.

Plastic frame type: the plastic frame is wrapped on both sides of the mobile hard disk. The rubber frame type can reduce the vibration of the mobile hard disk in the horizontal and vertical directions, and its vibration reduction effect is better than that of the rubber pad type. However, the plastic frame needs to be set in the hard disk box or similar hard disk box for overall limit. For devices without hard disk enclosures, it is difficult to fix the plastic frame on the equipment, and an additional hard disk enclosure-like structure needs to be installed, resulting in high costs.

The effect is good.

After the existing rubber frame damping structure is wrapped on the hard disk, the hard disk box is required to limit the plastic frame damping structure as a whole, so as to prevent the assembly of the rubber frame damping structure and the hard disk from being in the inner cavity of the mobile storage device. Moving in the middle, hitting the inner wall of the mobile storage device, so that the existing rubber frame type vibration damping structure cannot achieve the expected vibration damping effect. For a mobile storage device without a hard disk box, this embodiment can be connected to the mobile storage device through the connecting body 20, and then the hard disk vibration damping device 100 is fixed on the mobile storage device, and no hard disk box is required to install the hard disk vibration damping device 100. The limit is on the mobile storage device. When the mobile storage device is shaking, since the connecting body 20 is connected to the mobile storage device, the connecting body 20 will not move in the inner cavity of the mobile storage device, and the assembly of the hard disk vibration damping device 100 and the hard disk 200 in this embodiment will not It will move in the inner cavity of the mobile storage device and will not hit the inner wall of the mobile storage device, so that the hard disk vibration damping device 100 of this embodiment can achieve the expected vibration damping effect.

The connecting body 20 is used as the connecting structure between the hard disk vibration damping device 100 and the mobile storage device, which occupies much less space and volume than the hard disk box, and the cost is also lower than that of the hard disk box. The hard disk vibration damping device 100 of this embodiment not only has a good vibration damping effect, but also has low cost. Wherein, the hard disk 200 in this embodiment may be a mechanical hard disk or a solid state hard disk.

The first direction and the second direction are perpendicular to each other, that is, the extending directions of the first damping portion 11 and the second damping portion 12 are perpendicular. As shown in FIG. 4 , the first vibration-damping part 11 has a first bonding surface 111 , and the second vibration-damping part 12 has a second bonding surface 121 . As shown in Figure 5, the first direction is the horizontal direction, and the second direction is the vertical direction.

The connecting body 20 also functions to support the hard disk 200. For hard disks 200 of different sizes, elastic bodies 21 with different diameters and wall thicknesses can be selected to optimize the supporting function and vibration reduction function. For example, for a 3.5-inch hard disk 200, the diameter and wall thickness of the elastic body 21 can be increased to improve the supporting function. For the 2.5-inch hard disk 200, the diameter and wall thickness of the elastic body 21 can be reduced to ensure the support function and optimize the vibration reduction function.
