背景技术Background technique
电器设备在搬运和运输过程中一般会承受冲击、振动等载荷，为了避免电器设备受到破坏，会采用包装结构将电器设备包装起来，减少在搬运和运输过程中冲击和振动对电器设备的损坏。包装组件大多采用瓦楞纸箱和泡沫结构，将泡沫组合置于瓦楞纸箱内，以包裹覆盖电器设备的部位外周面，起到防护电器设备的作用。同样的，包装结构在防护电器设备的过程中也会承受冲击、振动等载荷。在冲击力聚集时，容易造成包装结构损坏，无法起到防护电器设备的作用。Electrical equipment generally withstands loads such as shock and vibration during handling and transportation. In order to avoid damage to electrical equipment, packaging structures are used to package the electrical equipment to reduce damage to electrical equipment caused by shock and vibration during handling and transportation. Most of the packaging components use corrugated cartons and foam structures. The foam combination is placed in the corrugated carton to wrap and cover the outer peripheral surface of the electrical equipment to protect the electrical equipment. Similarly, the packaging structure will also bear loads such as shock and vibration during the process of protecting electrical equipment. When the impact force accumulates, it is easy to cause damage to the packaging structure and fail to protect electrical equipment.

Referring to Figure 1, the packaging component includes two foams 100' arranged on opposite sides of the product to be protected. The two foams 100' are relatively separated. There is no integration between the two foams 100' and there is no stability. properties, and the buffer protection area provided by the two separated foams to the product is limited and cannot form a comprehensive protection.

近年来，凝聚态物理中的拓扑绝缘体得到了广泛的研究，电子能带性质逐渐从电子体系延伸到光子晶体、声子晶体等人工晶体(超材料)之中。在拓扑框架下，一些十分新奇的量子物理效应，如量子霍尔效应、量子自旋霍尔效应及量子谷霍尔效应逐渐地被发现和证实。类似于电子体系，拓扑经典波动***也会产生沿材料边缘传播的无带隙边缘态。这些边缘态的存在和性质不依赖于边缘的具体形状，仅由体能带的拓扑性质决定，因此具有稳定的物理特性，可以引导波沿着边界无背反射及缺陷免疫的单向传播。这些效应的引入能够为拓扑超材料的设计设定新的准则，为其在弹性波调控、振动隔离、滤波以及其他方面的应用奠定基础。 In recent years, topological insulators in condensed matter physics have been extensively studied, and the electronic band properties have gradually extended from electronic systems to artificial crystals (metamaterials) such as photonic crystals and phononic crystals. Under the topological framework, some very novel quantum physical effects, such as quantum Hall effect, quantum spin Hall effect and quantum valley Hall effect, have been gradually discovered and confirmed. Similar to electronic systems, topological classical wave systems also produce gapless edge states that propagate along the edge of the material. The existence and properties of these edge states do not depend on the specific shape of the edge, but are only determined by the topological properties of the body energy band. Therefore, they have stable physical properties and can guide the unidirectional propagation of waves along the boundary without back reflection and defect immunity. The introduction of these effects can set new criteria for the design of topological metamaterials and lay the foundation for their applications in elastic wave regulation, vibration isolation, filtering and other aspects.
霍尔效应由美国物理学家Edwin.H.Hall于1879年发现。1980年，德国物理学家Von Klitzing发现了整数量子霍尔效应：在低温强磁场条件下，霍尔电阻与磁场不再呈现线性关系，而是出现一系列量子化的平台，平台处电阻为h/(ne2)。依赖于QHE的声学或力学超材料往往需要一些主动的器件，如陀螺仪、旋转的流体或者施加外界场(如磁场)等，用于破坏时间的对称性。但这会增加***的复杂度，所以基于QHE的超材料结构往往难以在实际工程中应用。The Hall effect was discovered by American physicist Edwin.H.Hall in 1879. In 1980, German physicist Von Klitzing discovered the integer quantum Hall effect: under low temperature and strong magnetic field conditions, the Hall resistance and the magnetic field no longer show a linear relationship, but a series of quantized platforms appear, and the resistance at the platform is h /(ne2). Acoustic or mechanical metamaterials that rely on QHE often require some active devices, such as gyroscopes, rotating fluids, or the application of external fields (such as magnetic fields), to destroy the symmetry of time. However, this will increase the complexity of the system, so QHE-based metamaterial structures are often difficult to apply in actual engineering.
2005年，Kane和张首晟等分别基于零磁场下的石墨烯结构发现了QSHE，并提出采用自旋陈数用于描述拓扑绝缘体的拓扑性质。基于QSHE效应的拓扑超材料只需利用被动的器件，但为了在频散曲线中形成双Dirac点往往需要对几何进行复杂的调节。最近，电子的谷自由度作为一种新型的信息传播载体，受到了越来越多的学者关注。目前，人们已经通过理论预测和实验观察到许多谷态输运的特性，如谷分离、QVHE等。基于QVHE的超材料结构依赖于破坏结构的镜面对称性来实现拓扑性质，在实验室中相对较容易实现。QVHE源自于二维石墨烯结构中新发现的电子的谷自由度，谷自由度具有简并的性质，标记了能量的极值状态，但在动量空间上分离很远。正是由于这种较大的分离性质，避免了谷自由度之间的散射，使得谷自由度与电子的自旋自由度类似，在拓扑交界面上能够形成方向相反且具有鲁棒性的边缘模态。利用这一特性，设计出新型的拓扑声学和力学超材料***，从而实现能量在含有锐弯的拓扑波导中进行无后反射且鲁棒性传播。In 2005, Kane, Zhang Shousheng and others discovered QSHE based on the graphene structure under zero magnetic field, and proposed to use spin Chen number to describe the topological properties of topological insulators. Topological metamaterials based on the QSHE effect only need to use passive devices, but in order to form double Dirac points in the dispersion curve, complex adjustments to the geometry are often required. Recently, the electronic valley degree of freedom, as a new type of information dissemination carrier, has attracted more and more attention from scholars. At present, many characteristics of valley transport, such as valley separation, QVHE, etc., have been observed through theoretical predictions and experiments. QVHE-based metamaterial structures rely on breaking the mirror symmetry of the structure to achieve topological properties, which are relatively easy to implement in the laboratory. QVHE originates from the newly discovered valley degrees of freedom of electrons in the two-dimensional graphene structure. The valley degrees of freedom have degenerate properties and mark the extreme states of energy, but are far apart in momentum space. It is precisely because of this large separation property that scattering between valley degrees of freedom is avoided, making the valley degrees of freedom similar to the spin degrees of freedom of electrons, and able to form opposite and robust edges on the topological interface. modal. Taking advantage of this characteristic, a new topological acoustic and mechanical metamaterial system is designed to achieve back-reflection-free and robust propagation of energy in topological waveguides containing sharp bends.
QSHE和QVHE这两种效应由于没有外加的主动元素，均没有破坏时间对称性，出现了两条对称的边缘模态，同一频率下相反方向的自旋态和谷态都能够被激发出来。但是由于两条边缘模态的相位相反，若激励形式与某一边缘模态的幅值和相位相互耦合，则能够激发出某一特定方向的自旋态或谷态，这就是自旋态和谷态的所具有的选择性激发。Since there are no external active elements, the two effects of QSHE and QVHE do not destroy the time symmetry. Two symmetrical edge modes appear. Both spin states and valley states in opposite directions at the same frequency can be excited. However, since the phases of the two edge modes are opposite, if the excitation form is coupled with the amplitude and phase of a certain edge mode, a spin state or valley state in a specific direction can be excited. This is the spin state and The selective excitation of the valley state.
另一方面，上述包装组件在角跌工况下，角部泡沫容易发生能量聚集和应力集中，导致包装结构发生破坏，进而使得所保护的产品发生损坏，造成额外损失。通过对包装组件进行强度分析可知，包装组件的本体和棱均具有较强的强度。相关技术中的包装组件的冲击能量沿着本体传播，因此需要足够的厚度吸能才能保护产品，从而增加了包装组件的生产成本。On the other hand, when the above-mentioned packaging components are in corner fall conditions, the corner foam is prone to energy accumulation and stress concentration, leading to damage to the packaging structure, which in turn causes damage to the products being protected, causing additional losses. Through the strength analysis of the packaging components, it can be seen that the body and edges of the packaging components have strong strength. The impact energy of the packaging component in the related art is propagated along the body, so sufficient thickness is required to absorb energy to protect the product, thereby increasing the production cost of the packaging component.

以通孔300的任意一个角为例，该角与底板200的其中一个边对应，并且位于该边的中点。通孔300的三个边分别和底板200另外的三个边平行。在该中条件下可以认为转角为0°。在转角为0°度的条件下，底板200上的正三角形的开口501面积可以尽可 能地增大，能够在减少材料使用量的同时能够增加弹性波的传递能量。Taking any corner of the through hole 300 as an example, this corner corresponds to one of the sides of the base plate 200 and is located at the midpoint of the side. The three sides of the through hole 300 are respectively parallel to the other three sides of the bottom plate 200 . Under these conditions, the rotation angle can be considered to be 0°.

Under these conditions, the rotation angle can be considered to be -30° or 30°. Similarly, when the rotation angle is -30° or 30°, the area of the equilateral triangle opening 501 on the bottom plate 200 can be increased as much as possible, which can reduce the amount of material used and increase the transmission energy of elastic waves.

为了能够说明力传递结构100的结构及原理以下将具体说明：In order to be able to explain the structure and principle of the force transmission structure 100, the following will be described in detail:
本申请实施方式的底板200可以为弹性超材料，等效材料参数，弹性模量，泊松比，晶格常数，板厚，正三角形边长。The base plate 200 in the embodiment of the present application can be an elastic metamaterial, equivalent material parameters, elastic modulus, Poisson's ratio, lattice constant, plate thickness, and side length of an equilateral triangle.
本申请实施方式通过在正六边形的底板200上开设正三角形的通孔300，通过对底板200的通孔300的转角的调整，以实现对板波的调制。In the embodiment of the present application, an equilateral triangular through hole 300 is opened on the regular hexagonal base plate 200 and the rotation angle of the through hole 300 of the base plate 200 is adjusted to achieve modulation of the plate wave.
具体地，结合图3以及图4，当底板200对应的转角时，体系具有对称性，如图3b所示。根据群论的知识，在倒空间布里渊区边界角点对应的点群具有二维不可约表示，因此在和点处会形成线***叉的狄拉克锥。如图4e中的交点，在频率340Hz附近简并形成狄拉克锥，插图表示倒空间第一布里渊区。Specifically, with reference to Figures 3 and 4, when the bottom plate 200 rotates correspondingly, the system has symmetry, as shown in Figure 3b. According to the knowledge of group theory, the point group corresponding to the boundary corner point of the Brillouin zone of the inverted space has a two-dimensional irreducible representation, so a linear intersection Dirac cone will be formed at the sum point. As shown in the intersection in Figure 4e, degeneracy forms a Dirac cone near the frequency of 340 Hz, and the inset represents the first Brillouin zone of inverted space.
另一方面，结合图3以及图4，当转角，存在两种条件可以满足对称：(记为结构A)和(记为结构B)。图4d和图4f给出了单胞的频散特性和一种构型转换到另一种构型时所对应的带隙翻转特性。由于结构的对称性受到破坏，在第一条和第二条带隙之间出现了一个完全的禁带，频率范围为309Hz～351Hz。尽管结构A和结构B两种构型的散射曲线一样，但它们对应的拓扑性质发生了改变，第一条和第二条两个带隙的拓扑性质发生转变称为带隙翻转。通过描述K点的模态的幅值和相位，可以发现模态发生了翻转。On the other hand, combined with Figure 3 and Figure 4, when turning a corner, there are two conditions that can satisfy symmetry: (denoted as structure A) and (denoted as structure B). Figure 4d and Figure 4f show the dispersion characteristics of the unit cell and the corresponding band gap flipping characteristics when one configuration is converted to another configuration. Due to the destruction of the symmetry of the structure, a complete forbidden band appears between the first and second band gaps, with a frequency range of 309Hz to 351Hz. Although the scattering curves of structure A and structure B are the same, their corresponding topological properties have changed. The transformation of the topological properties of the first and second band gaps is called band gap flipping. By describing the amplitude and phase of the mode at point K, it can be found that the mode has flipped.
上述的带隙翻转现象类比与谷态霍尔效应，进一步地，可以计算谷态陈数用以定量的描述拓扑相变。将Berry曲率在一半布里渊区中积分，表达式为公式1)，该公式1)为：其中Ω(k)为Berry曲率，表达式为公式2)，该公式2)为：这里，公式2)中，i为虚数单位，c.c.表示共轭复数，<·|·>表示内积，k＝[kx,ky]为Bloch波矢，以及ωu和ωv表示对应特征向量u和v的固有频率。结构A和结构B在K点对应的谷陈数为±1/2，两种结构对应 的谷态陈数为1，表明在两种结构的交界面处会出现拓扑保护边缘模态。The above-mentioned band gap flipping phenomenon is analogous to the valley Hall effect. Furthermore, the valley Chern number can be calculated to quantitatively describe the topological phase transition. Integrating the Berry curvature in half of the Brillouin zone, the expression is formula 1), which formula 1) is: Among them, Ω(k) is Berry curvature, and the expression is formula 2), which formula 2) is: Here, in formula 2), i is the imaginary unit, cc represents the conjugate complex number, < · | · > represents the inner product, k = [k x , k y ] is the Bloch wave vector, and ω u and ω v represent the corresponding features. The natural frequencies of vectors u and v. The corresponding Valley-Chern number of structure A and structure B at point K is ±1/2, and the two structures correspond to The valley Chern number is 1, indicating that a topologically protected edge mode will appear at the interface of the two structures.
具有相反转角的弹性声子晶体属于不同的拓扑谷相。结构A和结构B沿方向以ABA的方式拼接，排布示意图如图6所示，实际计算时方向共有24个周期单元，两端设为连续边界条件。如此组成的ABA结构存在AB和BA两种不同界面，计算得到的投影能带如图7所示，图7中存在两条界面态色散，分别对应AB界面和BA界面。两条界面态均具有无带隙的特征，即色散贯穿整个体能带的带隙频率范围，可以发现，能量聚集在界面位置。Elastic phononic crystals with opposite rotation angles belong to different topological valley phases. Structure A and Structure B are spliced along the direction in an ABA manner. The arrangement diagram is shown in Figure 6. In actual calculation, there are 24 periodic units in the direction, and both ends are set as continuous boundary conditions. The ABA structure composed in this way has two different interfaces, AB and BA. The calculated projected energy band is shown in Figure 7. In Figure 7, there are two interface state dispersions, corresponding to the AB interface and the BA interface respectively. Both interface states have the characteristics of no bandgap, that is, the dispersion runs through the bandgap frequency range of the entire bulk energy band. It can be found that the energy is concentrated at the interface location.
基于以上情况，在本实施方式中将具有拓扑结构的力传递结构100与包装相结合。由于产品跌落时，角与地面的接触时间基本确定，将产生特定频率的弹性波。对于包装结构而言，发生角跌时能量往往集中在角的位置或者传递到包装结构的体内，因此往往要求泡沫100’尺寸较厚才能保护产品不被损坏。图7为本申请实施方式的包装组件400的结构示意图，其应用了以上力传递结构100的泡沫100’设计，棱的两面由相反的谷拓扑相构成，在交界面形成了拓扑保护的边界态，从而引导角位置的能量沿着棱传播，避免了能量在角的位置过度聚集，防止包装结构发生破坏。Based on the above situation, in this embodiment, the force transmission structure 100 with a topological structure is combined with packaging. Since the contact time between the corner and the ground is basically determined when the product falls, elastic waves of a specific frequency will be generated. For packaging structures, when a corner falls, the energy is often concentrated at the corners or transferred to the body of the packaging structure. Therefore, the foam 100' is often required to be thicker to protect the product from damage. Figure 7 is a schematic structural diagram of the packaging component 400 according to the embodiment of the present application, which applies the foam 100' design of the above force transmission structure 100. Both sides of the edge are composed of opposite valley topological phases, forming a topologically protected boundary state at the interface. , thereby guiding the energy at the corner position to propagate along the edge, avoiding excessive accumulation of energy at the corner position, and preventing damage to the packaging structure.
在本申请实施方式中，包装组件400包括多个防护件401，相邻的两个防护件401连接，防护件401包覆于待包装物品，至少一个防护件401设置有上述的力传递结构100。In the embodiment of the present application, the packaging assembly 400 includes a plurality of protective members 401. Two adjacent protective members 401 are connected. The protective members 401 cover the items to be packaged. At least one protective member 401 is provided with the above-mentioned force transmission structure 100. .
其中，至少一个防护件401上设置有上述的力传递结构100，包装组件400和待包装物品的整体在运输过程中出现碰撞跌落等情况时，能量能够沿着力传递结构100的边沿传递。减少包装组件400的损坏，提高了对待保证物品的防护作用，同时能够减少成本。Among them, at least one protective piece 401 is provided with the above-mentioned force transmission structure 100. When the packaging assembly 400 and the entire item to be packaged collide and fall during transportation, energy can be transmitted along the edge of the force transmission structure 100.

在一些实施方式中，多个力传递结构100拼接形成防护件401。即在防护件401上设置多个力传递结构100，可以是防护件401全部设置力传递结构100，也可以是防护件401的部分设置力传递结构100。In some embodiments, multiple force transmission structures 100 are spliced to form a protective component 401 . That is, multiple force transmission structures 100 are provided on the protective piece 401. The force transmission structures 100 may be provided on all of the protective piece 401, or on part of the protective piece 401.
在一些实施方式中，多个防护件401连接形成包装组件400，包装组件400具有多个表面，在相邻的两个表面中，力传递结构100的通孔300的第一顶点301位于同一直线的相反方向上。In some embodiments, multiple protective pieces 401 are connected to form a packaging assembly 400. The packaging assembly 400 has multiple surfaces. On two adjacent surfaces, the first vertex 301 of the through hole 300 of the force transmission structure 100 is located on the same straight line. in the opposite direction.
力传递结构100的通孔300的第一顶点301位于同一直线的相反方向上则说明相邻两个防护件401的拓扑相相反，在交界面形成了拓扑保护的边界态，从而引导角位置的能量沿着棱传播，避免了能量在角的位置过度聚集，防止包装结构发生破坏。、If the first vertex 301 of the through hole 300 of the force transmission structure 100 is located in the opposite direction of the same straight line, it means that the topology of the two adjacent protective parts 401 is opposite, forming a topologically protected boundary state at the interface, thereby guiding the angular position. Energy spreads along the edges, avoiding excessive energy accumulation at the corners and preventing damage to the packaging structure. ,
在一些实施方式中，相邻的两个表面的通孔300的转角不同。 In some embodiments, the through holes 300 on two adjacent surfaces have different turning angles.
有相反转角的力传递结构100属于不同的拓扑谷相。结构A和结构B沿方向以ABA的方式拼接，排布示意图如图5所示，实际计算时方向共有24个周期单元，两端设为连续边界条件。如此组成的ABA结构存在AB和BA两种不同界面，计算得到的投影能带如图7所示，图6中存在两条界面态色散，分别对应AB界面和BA界面。两条界面态均具有无带隙的特征，即色散贯穿整个体能带的带隙频率范围，可以发现，能量聚集在界面位置。The force transmission structures 100 with opposite rotation angles belong to different topological valley phases. Structure A and Structure B are spliced along the direction in an ABA manner. The arrangement diagram is shown in Figure 5. In actual calculation, there are 24 periodic units in the direction, and both ends are set as continuous boundary conditions. The ABA structure composed in this way has two different interfaces, AB and BA. The calculated projected energy band is shown in Figure 7. In Figure 6, there are two interface state dispersions, corresponding to the AB interface and the BA interface respectively. Both interface states have the characteristics of no bandgap, that is, the dispersion runs through the bandgap frequency range of the entire bulk energy band. It can be found that the energy is concentrated at the interface location.
基于上述分析，本申请实施方式的力传递结构100包括两个以上的拓扑单元，相邻的两个拓扑单元连接，每个拓扑单元均包括多个底板200，相邻的拓扑单元中的底板200的布置方向相同，底板200的转角不同。Based on the above analysis, the force transmission structure 100 of the embodiment of the present application includes more than two topological units.
