Problems solved by technology

While such isolation systems are effective at isolating vibrations, they are bulky, complex to set up, and difficult to install due to the tight space between the case and the hard drive
Of course, they can also be installed outside the chassis, but they will also occupy a large area, and in many practical applications, the price is too expensive to bear

Embodiment Construction

[0022] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described with reference to the accompanying drawings, and the same or similar symbols in each figure represent the same or similar parts.

[0023] Combine now Figure 1a-1c Briefly explain the working principle of the rubber vibration isolator of the present invention.

[0024] like Figure 1a As shown, an ordinary spring 24 is subjected to a downward pressure F S Under the action of , it is compressed δ, F S The ratio to δ is the positive stiffness coefficient K of the spring 24 S , the positive stiffness coefficient of the spring 24 is related to the material and shape of the spring.

[0025] like Figure 1b Shown is a mechanism 22 for achieving negative stiffness having a long rod 222 with a hinge 26 in the center and a pivot 224 at each end of the rod 222 . For ease of descri...

Abstract

The invention provides a rubber vibration isolator, comprising a rubber part and a compressing part, wherein the rubber part comprises a transverse rubber part and a longitudinal rubber part; and the longitudinal rubber part is divided into two parts with symmetrical shapes and the two parts are positioned at the two sides of the transverse rubber part. In the direction vertical to the longitudinal axis of the rubber part, the stiffness coefficient of the transverse rubber part is KS, the negative stiffness coefficient of the longitudinal rubber part is KN, the KN absolute of the longitudinalrubber part is equal to KS of the transverse rubber part, and the compressing part compresses the rubber part on the bearers. The rubber vibration isolator has simple structure and zero stiffness coefficient of the rubber vibration isolator can be realized by adjusting the stiffness coefficient of the positive and negative stiffness mechanisms so as to block vibration with various frequencies, especially low-frequency vibration.

Description

technical field [0001] The invention relates to a rubber vibration isolator, in particular to a zero-stiffness rubber vibration isolator for blocking low-frequency vibrations, and is especially suitable for vibration isolation of hard disk drives and the like. Background technique [0002] Most industrial personal computers (industrial personal computers) have data storage components, such as hard disk drives (HDD) and optical drives with read-only memory (CD-ROM), which transmit data at high speeds and store data Due to their high density, they are very sensitive to severe vibrations and impacts. During operation, storage or transmission, any shock may cause data loss or even damage the drive. Therefore, in order to ensure the performance and safety of the industrial computer, it is necessary to prevent the drive on it from external vibrations, so the general industrial computer has a reinforcement design. [0003] Generally speaking, passive vibration isolators are usual...
