However, the drawings are only schematic illustrations of the invention and are not drawn to scale. The same parts in the figures are given the same reference numerals, and repetitive descriptions are omitted.

[First Embodiment]

Figures 1a and 1b illustrate a structure of the power generation cloth of the present invention. As shown in FIG. 1 a , the power generation cloth of the present invention includes a first friction component 1 , a second friction component 2 , an anti-skid bottom layer 3 , a coil component 4 and a magnet component 5 . Wherein, the main body of the power generation cloth includes a first friction component 1 and a second friction component 2 . When pressure is applied to the surface, the two come into contact, and when the pressure is no longer applied, the two separate, the mechanical energy represented by the applied pressure during the contact and separation process is converted into electrical energy, and the coil assembly 4 and the magnet assembly 5 will eventually Generated electrical output. These components will be described in detail below.

The construction of the first friction assembly 1 of the present invention is described below with reference to Figures 2a-2f. The first friction assembly 1 includes: a belt-shaped fabric composite layer 11 ; a conductive fabric layer 12 ; and a loop-shaped fabric composite layer 13 .

In this embodiment, as shown in FIGS. 2 a to 2 c , the first friction component 1 includes a plurality of belt-shaped fabric composite layers 11 . Each belt-like fabric composite layer 11 extends in the length direction (eg, the x-direction in FIG. 2 a ), and a plurality of belt-like fabric composite layers 11 are arranged in parallel in the width direction (eg, the z-direction in FIG. 2 a ) to A fabric composite layer is formed.

The belt-shaped fabric composite layer 11 is, for example, a fully integrated belt-shaped fabric composite layer formed by chemical cross-linking of one or more polymer material layers and electrode layers. The polymer material can be a high molecular polymer material, such as polydimethylsiloxane, barium titanate doped polydimethylsiloxane, polytetrafluoroethylene, polyvinyl chloride or fluororubber, etc. The electrode layer can be Conductive fabric materials, such as silver cloth or copper-nickel alloy cloth, etc.

In the example shown in FIG. 2 c , the tape-like textile composite layer 11 comprises a layer 111 of polymer material and a layer 112 of electrodes. The length of the electrode layer 112 of the belt-like fabric composite layer 11 is greater than the length of the polymer material layer 111 at one end in the length direction thereof, so that a part of the electrode layer 112 is exposed.

The conductive fabric layer 12 may be formed of the same or similar type of conductive fabric material as the electrode layer 112 of the tape-like fabric composite layer 11 . The conductive fabric layers 12 may be tape-shaped, and each conductive fabric layer 12 is located between two adjacent stacked tape-shaped fabric composite layers 11, and the three are formed in a parallel structure similar to a sandwich layer structure. In the example shown in Fig. 2c, in the thickness direction (y direction in Fig. 2a), a conductive fabric layer 12 is sandwiched between two belt-like fabric composite layers 11. The length of the strip-shaped conductive fabric layer 12 at one end in its length direction is greater than the length of the strip-shaped fabric composite layer 11 covering the conductive fabric layer 12, so that a part of the conductive fabric layer 12 is not covered by the strip-shaped fabric composite layer. 11 is covered and exposed, and the exposed portion of the conductive fabric layer 12 is opposite to the exposed portion of the electrode layer 112 in the thickness direction (the y direction in FIG. 2a ).

The loop fabric composite layer 13 may be formed of the same or similar material/structure as the tape fabric composite layer 11 . For example, the loop-shaped fabric composite layer 13 is formed using the same material as the tape-shaped fabric composite layer 11 , and includes the same polymer material layer 131 and electrode as the polymer material layer 111 and the electrode layer 112 of the tape-shaped fabric composite layer 11 , respectively. Layer 132. The polymer material layer 131 covers part of the electrode layer 132, and the uncovered electrode layer forms a bare part. The loop-shaped fabric composite layer 13 forms a loop-shaped structure surrounding the outside of the strip-shaped fabric composite layer 11 and the conductive fabric layer 12 in the width direction of the tape-shaped fabric composite layer 11 and the conductive fabric layer 12 . The number of turns of the loop-like structure may be one or more. The number of turns of the loop-shaped fabric composite layer 13 in Figs. 2a-2d of this example is one layer, but the number of turns may also be multiple. When it is 2 or more, the loop-like fabric 13 is constructed as a multi-layer loop-like structure, that is, the number of windings is greater than that of the loop-like fabric 13 shown in FIG. 2a. In the example shown in Figs. 2a-2c, the loop-shaped fabric composite layers 13 are plural in number, which are arranged parallel to each other in the width direction and separated by fixed intervals in the length direction. The electrode layers 132 of the plurality of loop-shaped fabric composite layers 13 in the longitudinal direction are extended and connected in the longitudinal direction to form continuous strip-shaped electrode layers in the longitudinal direction. The power generation cloth of the present invention has an arch (or U-shaped) structure, which will be exemplarily described below. The strip-shaped fabric composite layer 11 and the conductive fabric layer 12 are stacked to form a strip-shaped structure in the thickness direction, and a plurality of strip-shaped structures are arranged side by side in the width direction, that is, the z-direction, and the electrode layers 112 in the z-direction pass between the rows. The electrical connection with the conductive fabric layer 12 respectively realizes structural fixation and circuit continuity, and forms the main body of the power generation cloth with a plane structure. Wherein, the electrical connection refers to the electrode layers of the positive and negative poles in the power generation cloth, and the electrode layers of the same pole are connected to each other by means such as bonding, respectively. The main body of the power generation cloth is bent (or folded) upward along the axis in the width direction of the strip structure (for example, the z direction in Fig. 2a ), to form an arch or U-shaped structure as shown in Fig. 2b. The arch (U-shaped) structure is not only a part of the fabric self-rebound structure of the main body of the power generation cloth, but also forms a two-electrode contact triboelectric power generation structure, which effectively improves the output electrical performance of the triboelectric power generation, and has stable Power generation capacity and good fatigue resistance. In the example shown in Figures 2a-2c, the power generation cloth is bent once to form an arched mechanism. However, the present invention is not limited to this, and the power-generating cloth can also be folded multiple times to form a multi-layer structure. For example, when the power generation cloth is bent twice, the power generation cloth forms a "Z"-shaped folded structure when viewed from the side, that is, a multi-layer structure formed by superimposing various layers of the U-shaped/arch-shaped structure.

The present invention provides an innovative composite weaving method, that is, a plurality of loop-shaped fabric composite layers 13 respectively surround the outer side of the strip-shaped structure formed by the belt-shaped fabric composite layer 11 and the conductive fabric layer 12, The two sides of the shaped structure are symmetrically or staggered to form the main body of the woven structure.

The circuit connection manner in the power generation cloth will be exemplarily described below. The electrode layers 112 of the one (or more) fabric composite layers 11 and the electrode layers 132 in the multiple loop-shaped fabric composite layers 13 are electrically connected to achieve circuit continuity; in one (or more) strip-shaped conductive fabric layers 12, Each row is a continuous strip structure, and each row is electrically connected to realize circuit continuity. Wherein, the electrical connection refers to the electrode layers of the positive and negative poles in the power generation cloth, and the electrode layers of the same pole are connected to each other by means such as bonding, respectively.

In the above Figures 2a-2d, Figure 2a is a schematic view from the front, and Figure 2b is a schematic view from the reverse side, ie from the opposite direction to Figure 2a. The viewing angle of Figure 2c is the same as that of Figure 2b. Figure 2c illustrates the electrical connection of the layers of the power-generating cloth. As shown in FIG. 2 c , in this example, the electrode layers 12 are connected to each other by means of bonding or the like in each row of the strip-shaped conductive fabric layers 12 . At the same time, the rows of electrode layers 112 of the fabric composite layer are connected to each other. However, since the electrode layer 112 of the fabric composite layer and the electrode layer 132 of the loop-shaped fabric composite layer 13 in the embodiment are electrode layers of the same polarity, they need to be connected together, and the connection method can be shown in Figure 2a. Figure 2e illustrates a schematic diagram of the structure of a power generation cloth with one layer of power generation cloth, Figure 2f illustrates a schematic diagram of the structure of a power generation cloth with two layers of power generation cloth, and Figure 2g illustrates a power generation cloth with three layers of power generation cloth layers. Schematic diagram of the structure of the cloth.

The non-conductive fabric 23 is a knitted fabric, a woven fabric or a 3D spacer fabric, or a fabric whose material is favorable for chemical cross-linking. The polymer material layer 21 may be a high molecular polymer material, such as polydimethylsiloxane, barium titanate doped polydimethylsiloxane, polytetrafluoroethylene, polyvinyl chloride or fluororubber, and the like. The material of the non-conductive fabric 23 can be cotton, polypropylene, nylon, polyacrylonitrile or polyethylene terephthalate, etc. The non-conductive fabric 23 can be flame-retardant treated with a flame retardant.

The power generation cloth of the present invention may further include a non-slip bottom layer 3 which covers the bottom surface of the power generation cloth main body. The material of the anti-slip bottom layer is woven or knitted fabric.

The power generation cloth of the present invention may also include at least one set of electromagnetic generator assemblies. In Figures 4a-4c, one configuration of an electromagnetic generator assembly is illustrated. The electromagnetic generator assembly includes a coil assembly 4 and a magnet assembly 5 . The coil assembly 4 is placed on the upper surface of the first friction assembly 1 , and the magnet assembly 5 is placed under the lower surface of the first friction assembly 1 . The second friction component 2 is used as a fabric outer layer, which completely covers the upper surface of the main body of the power generation cloth, that is, it is fixed on the upper surface of one or more sets of coil components 4, and the anti-skid bottom layer 3 covers the bottom surface of the main body of the power generation cloth, that is, it is fixed on the upper surface of the main body of the power generation cloth.

In Figs. 4a-4c, the first friction assembly 1 between the coil assembly 4 and the magnet assembly 5, and the second friction assembly and the magnet on the coil assembly 4 are omitted in order to more clearly reflect the structure of the generator. Anti-skid bottom layer under component 5.

The coil assembly 4 may include at least one of the following: a coil assembly 41 , a coil embroidered fabric 42 and a coil woven fabric 43 . For example, the coil assembly 41 is made of enameled copper wire and is wound into a hollow three-dimensional cylinder with the central axis as the base point. Enamelled copper wire and ordinary yarn are woven in a woven way.

The material of the magnet (magnet) component 5 can be a soft magnet, such as a flexible rubber magnet. The magnet assembly 5 includes a plurality of soft magnets with different polarities. The magnets with different polarities are alternately arranged in the axial direction. The magnetic differences between adjacent soft magnets attract each other to form the magnet assembly 5 .

The operation principle of the power generation cloth of the present invention will be described below. The contact parts of the first friction component 1 and the second friction component 2 have different friction electrode sequences. After the power generation cloth is subjected to pressure, the first friction component 1 and the second friction component 2 are in contact; the pressure of the power generation cloth After disappearing, the elastic recovery of the power generation cloth is realized by the first friction component 1, and the mutual separation of the first friction component 1 and the second friction component 2 is realized; Under the interaction of the pressure on the main body of the generator cloth and the elastic force generated by the first friction component 1, the reciprocating motion along the vertical line of the main body of the generator cloth enables the coil assembly 4 to cut the magnetic field lines of the magnet assembly 5, thereby generating electricity.

The above is an example of the configuration of the power generation cloth of the present invention. In the present invention, the electrical performance of the power generation cloth per unit area is determined by the power generation factor, and the electrical performance of the power generation cloth can be controlled by adjusting the value of the power generation factor. The power generation factor can be determined by the fabric composite layer 11 and the first friction component. The loop fabric composite layer 13 is determined. Among them, the electrical properties include the voltage, current and energy density output by the power generation cloth. The value of the power generation factor is determined by the following ratio: the product of the number of loops of the loop-shaped fabric composite layer and the number of the loop-shaped fabric composite layers per unit area, and the number of layers of the belt-shaped fabric composite layer and the ratio of the product of the surface area of the first friction component. When the magnitude of the power generation factor is represented by Y, it can be represented by the following formula (1).

Y=BC/(A·D) Formula (1)

The parameters in the above formula (1) respectively represent the following parameters.

A: The number of layers of the dimensionless first textile composite layer 11 , that is, the number of layers forming an arch or U-shaped structure. The number of layers is the number of parallel folded layers that can be woven by the loop-shaped fabric composite layer 13 in the first fabric layer 11 in the vertical direction of the power-generating cloth. Referring to Figures 2e-2g, Figure 2e represents a 1 layer, Figure 2f represents a 2 layer, and Figure 2g represents a 3 layer.

B: The number of loops of the dimensionless looped fabric 13 , that is, the number of loops of a single looped fabric composite layer 13 woven to form a looped structure along the periphery of the strip formed by the first fabric composite layer 11 and the electrode layer 12 . In the example of Figures 2a-2c, the number of turns is 3 turns.

C: The number of dimensionless third loop-shaped fabrics 13 , that is, the sum of the total number of loop-shaped fabric composite layers 13 in the main body of the power-generating cloth per unit area. Among them, the unit area can be defined by itself, such as per square centimeter, per square meter, and so on.

D: surface area of the dimensionless first friction component 1 . The surface area referred to by the surface area D refers to the entire upper surface area of the power-generating cloth, but does not include the area of the exposed electrode layer, that is, the effective area of the power-generating cloth for triboelectric power generation.

The following examples 1 and 2 will be used to illustrate that the power generation factor plays a decisive role in the electrical performance of the power generation cloth. By adjusting the value of the power generation factor, the electrical performance of the power generation cloth can be controlled, including voltage, current and energy density.

Example 1:

Take the power generation cloth in Figure 2e of the invention as an example.

The number of layers of the arched structure is 1, that is, A=0.2582 after dimensionless data processing. Among them, the dimensionless data processing method mentioned in this paper is to horizontally normalize the parameters in the experimental data.

The number of loops of the looped fabric 13 is 3, that is, B=0.6255 after the dimensionless data processing.

The number of loop fabrics 13 is 9, so C=0.2694 after dimensionless data processing

The effective surface area of triboelectric power generation on the entire upper surface of the power-generating cloth is 27 square centimeters. In this example, the unit area is defined as 1 square centimeter. Therefore, D=0.4450 after dimensionless data processing.

The power generation factor in this example 1 is about 0.2905 in a dimensionless case according to Y=BC/(A·D). Under the test conditions of human walking, the open-circuit voltage, short-circuit current and energy density generated by the power generation cloth are 363.0V, 6.63μA and 75.21mW·cm ^-2 , respectively.

Example 2:

Take the power generation cloth of Figure 2f of the invention as an example.

The number of layers of the arched structure is 2, and A=0.5164 after dimensionless data processing.

The number of loops of the loop fabric 13 is 2 layers, and B=0.4170 after dimensionless data processing.

The number of loop fabrics 13 is 15, and C=0.4490 after the dimensionless data processing.

The effective surface area of triboelectric power generation on the entire upper surface of the power-generating cloth is 30.09 square centimeters. In this example, the unit area is defined as 1 square centimeter, so after dimensionless data processing, D=0.4185.

At this time, the power generation factor is about 0.1517 in the case of dimensionless according to Y=BC/(A·D). Under the test conditions of human walking, the open-circuit voltage, short-circuit current and energy density generated by the power generation cloth are 437.3V, 19.94μA and 289.8mW·cm ^-2 , respectively.

The power generation factor in this embodiment will be described below with reference to FIG. 5 .

As shown in FIG. 5 , “BC” represents the product of the number of loops of the loop-shaped fabric composite layer 13 and the number of the loop-shaped fabric composite layers 13 after the dimensionlessization. "(A·D)" represents the product of the number of layers of the belt-like fabric composite layer 11 and the surface area of the first friction component 1 after dimensionlessization. The abscissa in FIG. 5 represents the ratio of the product of the number of turns of the loop-shaped fabric composite layer 13 and the number of loop-shaped fabric composite layers 13 to the product of the number of layers of the fabric composite layer 11 and the surface area of the first friction component 1 after dimensionlessization . The ordinate represents the output energy density of the power-generating cloth based on triboelectricity, and the present invention takes the energy density per unit area as an example. It can be seen from FIG. 5 that by changing the number of loops of the loop-shaped fabric composite layer 13 and the number of loop-shaped fabric composite layers 13, that is, the value of “BC”, and when the number of layers and the number of the different belt-shaped fabric composite layers 11 A product of the surface area of the friction component 1, that is, changing the value of "(A·D)", can change the output energy density of the power-generating cloth. With the increase of "BC/(A·D)", the energy density of the output electric energy shows a trend of first increasing and then decreasing. When the value of "BC/(A·D)" is 0, the energy density of the output electric energy tends to 0, but not 0. When the value of "BC/(A·D)" is between 0.08 and 0.17, the energy density of the output electric energy is high.

In the present invention, a power generation cloth based on triboelectric power generation is proposed through structural design and material selection. The power generation cloth has good elasticity and flexibility, and can convert various mechanical energy into electrical energy, and the power generation cloth has improved conversion efficiency, reducing resource waste to a certain extent.
