Description

Elastic structure

Technical Field

The invention relates to the field of building materials, in particular to an elastic structure.

Background

The spiral shape is popular in nature, and the spiral shape can solve the basic problem of spiral growth, which allows the growth pattern of animals and plants to be expanded without changing the basic shape. In this way, the organism can develop in harmony, for example, all the sprouts can enjoy the sun all day long due to the equiangular spiral arrangement of the branches and leaves. As described by darcy thoxpson (D' Arcy ThoXpsoY), the formation of different organisms in nature is due to different growth rates caused by accumulation, and the logarithmic growth pattern (equidistant helical pattern) is the simplest method for plants or animals. Thus, as the organism grows, a series of successive fragments will be displayed and the entire growth process will be completed by repeating these fragments. Therefore, animals and plants maintain a constant shape in nature. Based on this sequential similarity of equiangular helical growth, stress remains constant in different directions as the organism grows, so that offspring can inherit the largest characteristics.

However, the prior art does not apply the equiangular spiral structure to the production life, so it is highly desirable to provide a resilient structure formed by using the equiangular spiral pattern.

The number of the first lines and the second lines in fig. 1 is only schematically illustrated and is not particularly limited herein.

Referring to fig. 3, in this 3D model, the distance between two circles is the same, and thus the angle

And

are the same.

According to the characteristics of a logarithmic spiral, the angle between the tangent at point P and the radial line

Is constant. The path of the braiding thus conforms to the logarithmic spiral formula: r ═ ae ^bθ

In this formula: r is the distance to the origin (point o), θ is the angle to the x-axis, and a and b are arbitrary constants.

When the first and second threads are woven together in the present invention, the weave is an equiangular spiral, and since the equiangular spiral has the same characteristics as a spring, the entire structure can move in a vertical direction, having elasticity.

In some alternative embodiments, referring to fig. 6 and 7 in combination with fig. 1, fig. 6 and 7 are diagrams of hollow helix structures formed upon braiding. When the second thread is woven, the first point is placed close to the first thread, and the first thread is rotated counterclockwise to form a hollow spiral portion.

In the invention, the first line and the second line are crossed by winding in a counterclockwise direction during weaving.

In some alternative embodiments, with continued reference to fig. 1, the first wire comprises a metal wire and the second wire comprises a nylon wire.

The metal material has strength and toughness and can be used as a framework for supporting the elastic structure, so the metal wire is used as the first wire, and the nylon has good comprehensive properties including mechanical property, heat resistance, abrasion resistance, chemical resistance and self-lubricating property, so the nylon wire is used as the second wire, and the elastic structure is firmer by using the excellent mechanical property.

In some alternative embodiments, with continued reference to fig. 1, the second thread comprises a single nylon thread, or a plurality of nylon threads.

The second line in the invention can be a single line or a plurality of lines, and because the nylon line has excellent mechanical property, the elastic structure of the second line is stronger when a plurality of nylon lines are adopted.

In some alternative embodiments, when the second wire includes a plurality of nylon wires, each of the nylon wires is wound in a spiral shape at a prescribed lead angle and pitch to constitute the second wire.

In the embodiment, a plurality of nylon wires are woven by adopting a weaving means in the prior art, so that the elastic structure is firmer.

In some alternative embodiments, the outer surface of the first and/or second wire is coated with a titanium dioxide coating.

The embodiment can also coat titanium dioxide on the outer surface of the first line, the second line or the first line and the second line, and can degrade toxic and harmful pollutants such as nitrogen oxide (NOx) and Volatile Organic Compounds (VOC) under the irradiation of external light, so that the toxic and harmful gas is prevented from entering the room, and the aim of effectively isolating the toxic and harmful gas is achieved.

In some alternative embodiments, referring to fig. 1 and to fig. 8-15, X is between 3 and 16.

The number of first lines is shown in fig. 8 to 15 as 3, 4, 5, 6, 7, 8, 9, 10, respectively. Of course, the greater the number of first threads, the more elastic the resulting elastic structure is.
