Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings. For convenience of description, in an embodiment of the present invention, the axial direction of the inner shaft 1 is the Z-axis direction, the length direction of the bottom plate 17 is the X-axis direction, and the width direction of the bottom plate 17 is is the direction of the Y axis.

[0025] Shock absorber 25 of the present invention is as figure 1 and figure 2 As shown, it includes a first limiter, a second limiter and a third limiter, through which the three limiters can prevent the inner shaft 1, the inner shell 7 and the middle shell 9 from moving in the directions of the X-axis, Y-axis and Z-axis. degrees of rotational freedom.

[0026] The above three limiters will be described respectively below.

[0027] The first restrictor includes the inner shaft 1 and the inner shaft restrictor arranged on the inner shaft 1, specifically, the inner shaft restricto...

Abstract

The invention relates to a shock absorber device, in particular to the field of the motion carrier shock absorption technology. The shock absorber is used for solving the technical problems that in the prior art, a shock absorber cannot achieve non-angle displacement, or non-angle displacement is achieved bust the structure of the shock absorber is complex. The shock absorber device comprises a first limiter, a second limiter and a third limiter. The first limiter comprises an inner shaft and an inner shaft limiter arranged on the inner shaft. The second limiter comprises an inner shell and aninner shell limiter arranged on the inner shell. The third limiter comprises a middle shell and a middle shell limiter arranged on the middle shell. Through the above three limiters, the inner shaft,the inner shell and the middle shell only have the translation freedom degree in one direction, the rotating freedom degrees, in three directions, of the inner shaft, the inner shell and the middle shell are limited, and therefore coupled angle displacement is avoided.

Description

technical field [0001] The invention relates to the technical field of shock absorption for a moving carrier, in particular to a shock absorber. Background technique [0002] At present, the operating distance of the photoelectric detection equipment equipped on aircraft, vehicles and other moving carriers is calculated in kilometers. The angular displacement caused by the random vibration of the device carrier is amplified on the object side, resulting in a serious decline in image quality and tracking and aiming accuracy. The tracking and aiming accuracy and imaging quality of the photoelectric detection equipment on the moving carrier can generally isolate the low-frequency part of the random vibration of the moving carrier through the servo system. Due to the limited bandwidth of the servo system, its high-frequency part is often isolated through passive vibration reduction. At present, the passive vibration reduction methods of photoelectric detection equipment for movi...
