A kind of miniature slope shock absorber

Abstract

The invention discloses a miniature inclined surface vibration reducer. The miniature inclined surface vibration reducer comprises an outer barrel, an actuating piece, guiding rollers, roller shafts, two tension springs, a running pulley, a rolling shaft, a chute piece, an elastic baffle and a sunk screw, wherein the guiding rollers are respectively assembled at the upper end and the lower end of the actuating piece through the roller shafts to form an actuating subassembly; and the actuating subassembly freely moves along a longitudinal guide track on the inner wall of the outer barrel through the U-shaped guiding rollers. Longitudinal movement along an inclined surface of one side of the actuating piece is transformed into stretching and retracting of the tension springs, a longitudinal shock absorption function is fulfilled, the rigidity of the vibration reducer is greatly reduced by an inclined surface principle, and vibration of low frequency is isolated. Moreover, by a sleeve structure and the inclined surface, the size of the whole vibration reducer is reduced effectively, the vibration reducer can be well used in a small device with limited space, and the miniature vibration reducer can also serve as a low-rigidity vibration reduction module with single degree of freedom, so that a complex vibration reduction device with high requirements can be formed or established.

Description

technical field [0001] The invention relates to the field of vibration reduction, in particular to a miniature slope shock absorber, which is applied to occasions where the space is relatively limited and low-frequency vibration reduction and impact resistance are required, and can be applied to crystal oscillators, small electronic equipment, toys and other specific fields. Background technique [0002] Small devices such as small electronic equipment, airborne or missile-borne crystal oscillators need to achieve vibration reduction in a relatively limited space, so as to suppress the adverse effects of the vibration of the substrate on the characteristics of the output electrical signal of the electronic device. The existing vibration damping devices are generally suitable for medium and large structures, such as vibration dampers used in precision instruments, automobiles, construction machinery and other fields, and vibration dampers used in small and micro structures, es...

AI Technical Summary

Problems solved by technology

The existing vibration damping devices are generally suitable for medium and large structures, such as vibration dampers used in precision instruments, automobiles, construction machinery and other fields, and vibration dampers used in small and micro structures, especially in the field of electronic devices such as crystal oscillators. High-quality shock absorbers generally use rubber, steel wire ropes and elastic elements for vibration reduction, but in a very limited space, for light-weight vibration-damping objects, they usually cannot achieve vibration-damping effects when subjected to low-frequency vibrations.
