Problems solved by technology

And most precision instruments are high-precision instruments, which have extremely high requirements on the operating environment, and the slightest shaking will also affect the detection structure
[0003] Most of the existing damping structures are spring type, hydraulic type, electromagnetic type, etc. The spring type uses the deformation of the spring itself to absorb shock and shock absorption, but the deformation is still along the impact direction. There will be repeated up and down vibrations, and the amplitude attenuation speed is small, which is not conducive to meeting the shock absorption requirements of confidential instruments and other equipment; the hydraulic shock absorption structure is prone to oil leakage, and the manufacturing process is cumbersome and the production efficiency is low.
Spring type and hydraulic shock absorbers are relatively bulky, difficult to install and move, and are not suitable for delicate precision instruments
Although the electromagnetic can be made relatively compact, the electromagnetic type itself has an electromagnetic field, which affects the operation of the precision instrument itself.

Embodiment 1

[0032] Inspired by the above, the present invention provides a bionic shock-absorbing structure imitating annelids, which has many characteristics such as simple structure, convenient manufacture, durability and wide application.

[0033] Refer to attached figure 1 and attached figure 2 , we arrange a number of V-shaped folds 3 at equal intervals, on which a softer upper cushion 1 and a harder lower cushion 2 are arranged, and a flexible roller 4 is arranged under it, which are connected by rollers, wherein the V-shaped The folds 3, the softer upper buffer pad 1 and the harder lower buffer pad 2 can all be stretched.

[0034] The structure of the present invention specifically comprises the following steps:

[0035] Step A, during the impact process, the flexible roller 4 is the first to touch the ground, and while deforming itself to absorb part of the impact kinetic energy, it also transmits the impact force to the V-shaped folds 3, and the V-shaped folds 3 stretch rapidl...

Embodiment 2

[0042] Studies have shown that when the V-shaped folds 3 are also divided into V-shaped folds 3 that are separated from each other in the direction perpendicular to the paper, the superposition of the V-shaped folds 3 in two vertical directions becomes a more complex regular pyramid-shaped fold 5, Such as image 3 As shown, the shock absorption effect is better, so it can be used as another embodiment of the present invention.

[0043] In this embodiment, we set the V-shaped pleats 3 in Embodiment 1 as a number of regular pyramid-shaped pleats 5 arranged in an array at equal intervals, on which a softer upper cushion 1 and a harder lower cushion are arranged. 2. Double layers with different hardness can be stretched, and the regular pyramid fold 5, the softer upper cushion 1 and the harder lower cushion 2 can also be stretched, and the elastic modulus of the regular pyramid fold 5 can make it Keep the original shape when there is no external force, and can quickly become flat...

Abstract

The invention discloses a bionic damping structure imitating an annelid. The structure is similar to V-shaped wrinkles of the epidermal part of an annelid leech, when encountering vertical impact force, the V-shaped wrinkles transform longitudinal squeezing into transverse extending, so that vertical movement during impact is transformed into transverse movement, the contact time is prolonged, thedeformation of the V-shaped wrinkles can also make a large amount of impact energy absorbed, and thus the damping effect is achieved. The bionic damping structure comprises several V-shaped wrinkleswhich are distributed at equal intervals, dual-layer stretchable buffering cushions which are arranged on the V-shaped wrinkles and have different rigidities, and flexible idler wheels which are arranged below the V-shaped wrinkles. Compared with the prior art, the bionic damping structure has various advantages of being high in damping efficiency, simple in structure, free of maintenance, convenient to manufacture, light, reliable and the like.

Description

technical field [0001] The invention relates to the field of shock absorption, in particular to a bionic shock absorption structure imitating annelids. Background technique [0002] With the emergence of more and more precision instruments, there are more and more requirements for their anti-shock and shock absorption. Moreover, most precision instruments are high-precision instruments, which have extremely high requirements on the operating environment, and the slightest shaking will also affect the detection structure. [0003] Most of the existing damping structures are spring type, hydraulic type, electromagnetic type, etc. The spring type uses the deformation of the spring itself to absorb shock and shock absorption, but the deformation is still along the impact direction. There will be repeated up and down vibrations, and the amplitude attenuation speed is small, which is not conducive to meeting the shock absorption requirements of confidential instruments and other ...
