Abstract
The utility model discloses a mirror frame with negative Poisson's ratio effect, which comprises a mirror frame and a mirror ring, wherein the mirror frame and the mirror ring are of a perforation structure with periodic horizontal and vertical alternate holes; the hole shapes of the hole structures of the mirror frame and the mirror ring comprise an ellipse, a triangle and a polygon; the inner width L of the mirror frame is required to meet the following requirements: 120mm > L >139 mm; the thickness d of the mirror frame is required to be 2.5mm and d is more than 3.5 mm; the height H of the lens ring should satisfy: 15mm > H >36 mm. The utility model discloses utilize the material that has the hole structure that this method designed, have great negative poisson's ratio effect. The mirror frame shows a negative Poisson ratio effect under the condition of being pressed, and can bear larger impact force without breaking compared with the traditional mirror frame, thereby protecting the lenses and being lighter and higher in strength.
Description
Technical field
The utility model relates to a kind of frames designed using negative poisson's ratio hole configurations with Negative poisson's ratio, belong to
In new material and new construction field.
Background technique
Negative poisson's ratio material is a kind of material with tension expansion or compression retractable property, is a kind of with compared with senior engineer
The functional material of journey application value.Negative poisson's ratio material has special physics, machinery and deformation characteristic.For example, negative Poisson
Than the mechanical performance, including modulus of shearing, fracture toughness, thermal shock, intensity and pressure mottling resistance etc. that material can be improved in effect.Just
It is due to these excellent performances, negative poisson's ratio material is in Medical Devices, sensor, safeguard, aviation and navigation and national defence work
The fields such as journey have more and more wide application prospect.The production of three-dimensional negative poisson's ratio structure can combine 3D printing technique.3D
Technology is to realize the high-tech technology of rapid shaping to complicated structure using computer and three-dimensional printing technology.It is with digital mould
Based on type, so precision is high, mechanization degree is high, speed is fast.So the system of 3D printing technique and three-dimensional negative poisson's ratio structure
Combining is following trend, also can constantly mature and development.
Glasses are one of the articles that people are commonly used, but under many emergency cases, eye glass frame is easily snapped off, very
It flies out situations such as broken to eyeglass.Frame is made into negative poisson's ratio structure by the utility model, excellent using negative poisson's ratio material
Shock resistance and energy absorption characteristics, enable frame more preferably to resist impact force, to protect eyeglass.Hole configurations also allow its more
It is light.The utility model combines negative poisson's ratio structure and 3D printing manufacturing process, designs and makes and imitates with negative poisson's ratio
The frame answered.
Utility model content
The purpose of this utility model is in view of the deficiencies of the prior art, by negative poisson's ratio perforation structure and and 3D printing technique
It combines, has designed and manufactured the negative poisson's ratio frame of tool practicability, the frame of design has anti-impact more better than traditional frame
Hitting property, resistance to fracture, portability.
The technical solution adopted in the utility model are as follows: a kind of frame with Negative poisson's ratio, including mirror holder and Jing Quan,
The mirror holder is with the perforation structure for periodically replacing hole anyhow with Jing Quan；
The void shape of the hole configurations of the mirror holder and Jing Quan includes ellipse, triangle and polygon；
The frame inner width L should meet: 120mm > L > 139mm；Frame thickness d should meet 2.5mm > d > 3.5mm；
The Jing Quan height H should meet: 15mm > H > 36mm.
Preferably, described hole structure is metal material or plate.
A kind of design method of above-mentioned frame with Negative poisson's ratio, comprising the following steps:
1) shape and size of frame are determined according to different crowds, including mirror holder inner width, Jing Quan height and temple are long
The shape and size of degree；
2) that designs frame has periodically vertical and horizontal alternate hole configurations, and to the greatest extent in the case where meeting 3D printing requirement
Amount reduces the spacing of hole configurations；
3) frame with Negative poisson's ratio produced using 3D printing technique, the frame have high impact strength,
Meet the demand of actual use；
4) there is Negative poisson's ratio with the frame that the method generates, and has better shock resistance and lightweight high
Strong feature.
Its key for generating Negative poisson's ratio of the utility model is mirror holder and the negative poisson's ratio hole configurations of Jing Quan
Design.In the case where meeting 3D printing production requirement, guarantees that vertical and horizontal alternate cavernous structure is sufficiently small, have mirror holder and Jing Quan
There is Negative poisson's ratio, so that frame is whole also to have Negative poisson's ratio.The mirror holder that can be designed by this method and
Jing Quan has apparent Negative poisson's ratio, while negative poisson's ratio performance can be maintained in big range of strain.
The utility model has the advantages that the material with hole configurations that the utility model is designed using this method, has biggish negative
Effects of Poisson's ratio.The frame shows Negative poisson's ratio in the case of being pressurized, and more traditional frame can bear higher impact force
And it is not broken, to protect eyeglass, more high-strength light.
Detailed description of the invention
Fig. 1 is the overall schematic with Negative poisson's ratio frame；
Fig. 2 is the partial enlarged view of frame.
Specific embodiment
The utility model is described further with attached drawing combined with specific embodiments below:
As illustrated in fig. 1 and 2, a kind of frame with Negative poisson's ratio, including mirror holder 1 and mirror circle 2, the mirror holder 1 with
Mirror circle 2 is the perforation structure with periodically vertical and horizontal alternately hole；
The mirror holder 1 and the void shape of the hole configurations of mirror circle 2 include ellipse, triangle and polygon；The hole
Hole structure is metal material or plate；
The frame inner width L should meet: 120mm > L > 139mm；Frame thickness d is depending on lens thickness, generally are as follows:
2.5mm>d>3.5mm；
The 2 height H of mirror circle should meet: 15mm > H > 36mm.
A kind of design method of above-mentioned frame with Negative poisson's ratio, comprising the following steps:
1) shape and size of frame are determined according to different crowds, including mirror holder inner width, Jing Quan height and temple are long
The shape and size of degree；
2) that designs frame has periodically vertical and horizontal alternate hole configurations, and to the greatest extent in the case where meeting 3D printing requirement
Amount reduces the spacing of hole configurations；
3) frame with Negative poisson's ratio produced using 3D printing technique, the frame have high impact strength,
Meet the demand of actual use；
4) there is Negative poisson's ratio with the frame that the method generates, and has better shock resistance and lightweight high
Strong feature.
