Shock-absorbing device

Abstract

The invention relates to a vibration absorber and is characterized in that: the vibration absorber comprises a box which is matched with the shape of an article to be treated with vibration damping, the side wall of the box and a cover board at the top of the box are embedded or attached with vibration damping material, the bottom of the box is provided with a damping ring which is evenly wound with heat dispersing materials and is equipped with a lining board, and the article to be treated with vibration damping is fixed on the lining board; wherein, the preparing process of the heat dispersing materials is as follows: firstly the inner core of a shielding wire is drawn out to obtain an external shield metal mesh; then the external shield metal mesh is planished and shortened segment by segment to obtain the heat dispersing materials. The invention overcomes the defects of the prior art and provides the vibration absorber which can meet the operating environment requirements of a product needing both vibration damping and heat dissipation; the vibration absorber is especially suitable for the vibration damping of the small-scale articles with high accuracy requirements such as rubidium clocks, etc.

Description

technical field [0001] The invention relates to a vibration damping device, which is especially suitable for vibration damping of rubidium clocks and other small objects requiring high precision. Background technique [0002] With the continuous improvement of technology, in high dynamic carriers such as automobiles, aircraft and missiles, it is necessary to use rubidium clocks to provide time-frequency references with low aging, high accuracy and stability. However, since the structure of the rubidium clock itself is more precise, the circuit is more complicated, and the output frequency is greatly affected by vibration, so how to improve the anti-vibration performance of the rubidium clock plays a decisive role in the application effect of the rubidium clock in a high dynamic environment. In order to improve the anti-vibration performance of the rubidium clock, in addition to a reasonable structural design (mainly the appearance structure, installation position, fixing met...

AI Technical Summary

Problems solved by technology

Compared with small rubidium clocks, the above-mentioned vibration reduction objects generally consume less power and do not have the problem of heat dissipation, so the heat dissipation requirements are not considered in these vibration reduction designs

The rubidium clock is only 124ml in size, the power consumption is 18W when it is turned on, and the stable power consumption at room temperature is 7 watts. If heat dissipation is not considered, the temperature range of its normal operation will be shortened.
