Capsule-type vibration isolator of computer hard disk

Abstract

A capsule-type vibration isolator of computer hard disk mainly solves the technical problems of ultra-light load and ultra-small size of the vibration isolator. The adopted technical scheme is as follows: upper and lower splints are an integral plate body; a group of non-metallic capsules are uniformly distributed between upper and lower splints; the height of the formed vibration isolator does not exceed 25mm; the wall thickness of the non-metallic capsule is not greater than 1.5mm; the maximum diameter of the non-metallic capsule is not greater than 40mm; and the capsule-type computer hardware vibration isolator is suitable for the vibration reduction and impact resistance of various computer hard disks.

[0002] Computers are widely used in various fields. Computer hard disks are the most important external storage devices in computers. Almost all user applications, data, and documents are stored in hard disks. Hard disks are composed of magnetic heads, spindles, disks, drive mechanisms, and motors. , chip and interface, etc. The disk is fixed on the motor shaft and rotates at high speed, and the magnetic head can move radially along the disk. There is a very small gap between the two. The hard disk is installed in the hard disk bracket of the computer with screws. When the computer is subjected to a large vibration or impact in a practical environment, the hard disk will stop and crash; most of the existing computers work under the environmental conditions of no vibration or little vibration, and there is no way to reduce or isolate the vibration of the hard disk. However, in aircraft, vehicles, ships or other similar environments, the computer may work under the condition of a strong vibration source. Vibration reduction method, that is, the use of vibration-damping pads or vibration-damping springs, there is still no vibration-resistance and anti-shock technical solution for computer hard disks.

[0003] In the field of vibration reduction technology, a variety of vibration isolators are used for various equipment that need vibration reduction, so that the rigid connection between the equipment and the foundation is transformed into an elastic support, and the bladder type vibration isolator is widely used in power equipment Its structure is characterized by the fact that the vibration isolator includes upper and lower splints and air bags, and the upper and lower splints are equipped with accommodating grooves of a set shape, and each splint is composed of two or more layers , the end of the airbag can be accommodated in the accommodating groove, and then the multi-layer splint is fixed. This structure is like a "spring" using rubber elasticity, which is characterized by strong nonlinear characteristics. It can absorb high and low frequency vibrations, the natural vibration frequency of the system is very low, and its stiffness is easy to control, and its service life is long. Some of its characteristics are suitable for the vibration reduction requirements of computer hard disks, but the existing technical solutions, single capsule The load capacity of the vibration isolator is greater than 10 kg. Compared with the mass of the computer hard disk not exceeding 150 grams, it is almost an unselectable condition. The corresponding size is also a parameter that cannot be accommodated by the computer hard disk bracket. Due to the huge size of the above parameters Differences, no one in this technical field has special requirements for computer hard disks. Taking the existing technology of "capsule vibration isolator" as a reference point, seek a new breakthrough in computer hard disk vibration isolation technology
