Problems solved by technology

Common buffering schemes for landing mechanisms require very strict attitude control during landing, otherwise it will be difficult to achieve a corresponding buffering effect. At the same time, when the weight and volume of the landing payload are small, its installation layout is very difficult
Although the use of airbag cushioning can adapt to various landing attitudes, its composition and actions are relatively complex, such as the generation of high-temperature gas, gas temperature control, airbag deflation, and projectile throwing, etc., and the cost of implementation is relatively high. The landing of the payload is especially uneconomical

Embodiment Construction

[0020] Such as figure 1 As shown, a self-expandable multi-layer spherical buffer device includes an outer buffer layer 1, an inner buffer layer 2, a connecting layer 3, a rigid support layer 4, a suspension bracket 5, a buffer body 6 and an unlocking and separating device 7. The outer buffer layer 1 and the inner buffer layer 2 are deformable buffer materials, the deformation buffer force of the outer buffer layer 1 is small, and the deformation force of the inner buffer layer 2 is relatively large. The connection layer 3 is a thin metal plate, generally a pure aluminum plate, and its thickness is generally not more than 0.3mm, which is used to separate the inner buffer layer 2 and the outer buffer layer 3, so as to prevent the two from cutting into each other during the impact deformation process, and the buffer performance is out of control. . The inner diameter of the outer buffer layer 1 is equal to the outer diameter of the connecting layer 3, the outer diameter of the i...

Abstract

The invention discloses a multilayer spherical buffer device capable of automatically unfolding, which comprises an outer buffer layer, an inner buffer layer, a connecting layer, a rigid supporting layer, a suspension bracket, buffer bodies and an unlocking separating device, wherein the outer buffer layer and the inner buffer layer are connected with the connecting layer in a glue joint mode; the inner buffer layer is connected with the rigid supporting layer in the glue joint mode; a gap is formed in the outer buffer layer, the inner buffer layer and the connecting layer; the gap penetrates through the rigid supporting layer; the rigid supporting layer is composed of two hemisphere layers; the two hemisphere layers are connected into a whole body through the unlocking separating device; a to-be-buffered effective load is integrally connected with the suspension bracket; the suspension bracket is supported and buffered by n buffer bodies. The buffer device provided by the invention has the advantages that the design is simple, the adjustment is convenient, the landing demand is reduced, the landing reliability is increased, and the weight of the buffer device is reduced.

Description

technical field [0001] The invention relates to a buffer device, which is applied to the landing buffer of small payloads. Background technique [0002] With the development of my country's lunar and deep space exploration technology, it is necessary to realize the landing buffer of the corresponding payload in various ways. The common buffering scheme of the landing mechanism has strict requirements on the attitude control during landing, otherwise it will be difficult to achieve the corresponding buffering effect. At the same time, when the weight and volume of the landing payload are small, its installation layout is very difficult. Although the use of airbag cushioning can adapt to various landing attitudes, its composition and actions are relatively complex, such as the generation of high-temperature gas, gas temperature control, airbag deflation, and projectile throwing, etc., and the cost of implementation is relatively high. The landing of the payload is especially ...
