Abstract

The invention discloses an air spring vibration isolator with a diaphragm. The vibration isolator comprises the inner diaphragm and a shell, damping pores are formed in the inner diaphragm and divide inner air into an upper part and a lower part, and air exchange between an upper end air bag and a lower end air bag can be achieved through the damping pores; the upper portion of the shell is designed according to a parabola, the middle of the shell is zigzag, and the bottom of the shell is designed according to a spline. By means of the vibration reduction mechanism of an air spring, the upper air bag is almost closed, high in dynamic response speed and capable of effectively isolating impact vibration, the lower air bag is gradually compressed and closed in the deformation process of the vibration isolator to achieve double-air-bag vibration reduction, the vibration reduction efficiency is high, and the vibration reduction effect is good.

Description

technical field [0001] The invention relates to an air spring vibration isolator with a diaphragm capable of resisting shock and vibration, and belongs to the field of mechanical structure design. Background technique [0002] With the development of ultra-precision machining, precision instruments and electronic equipment and other technologies, the requirements for environmental vibration and impact protection are getting higher and higher. Especially for electronic equipment with increasingly large and complex systems, its vibration-sensitive components or circuit boards must be independently isolated from vibration to ensure that the equipment can work normally. Many modern electronic devices are developing towards lightweight and portable. For electronic devices working in a sports environment, vibration and shock issues are even more important. [0003] Impact isolation technology is involved in various sectors of the national economy, not only the electronics industr...
