[0003] Energy conversion is the conversion of environmental energy such as solar energy, thermal energy or mechanical energy into electrical energy. With the application and development of wearable electronic devices, the study of a system based on device self-generation has become an increasingly key technology. In order to seek a device that can convert green, clean and renewable environmental energy into electrical energy and provide continuous power, friction nano-power generation technology has emerged. The friction nano-generator is mainly based on the principle of triboelectricity and the electrostatic induction effect. It converts the mechanical energy applied by the outside world into electrical energy in the circuit through the contact and separation between two materials with different friction properties. Due to its advantages such as simple manufacturing materials, strong safety and large-scale production, the friction power generation technology has gradually become an increasingly widely used self-generation device.

Although the function of friction power generation is achieved, the exposed electrodes usually have poor safety, and the preparation and assembly processes of the friction layer are complicated and not integrated. As a result, the power generation cloth based on friction nano-power generation technology has the following defects: poor stability of internal mechanical components, low power generation performance, poor fatigue resistance and short service life.

[0023] In order to fully understand the present invention, the present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the described embodiments are only for illustrative purposes and are not intended to limit the scope of the present invention. However, the accompanying drawings are only schematic illustrations of the present invention and are not drawn according to a certain scale. The same parts in the figures are marked with the same reference numerals, and repeated descriptions are omitted.

[0024] [First embodiment]

[0025] Attached Figure 1a and 1b A structure of the power generation cloth of the present invention is illustrated. Figure 1a As shown, the power-generating cloth of the present invention comprises a first friction component 1, a second friction component 2, an anti-slip bottom layer 3, a coil component 4 and a magnet component 5. Among them, the main body of the power-generating cloth comprises the first friction component 1 and the 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. During the contact and separation process, the mechanical energy represented by the pressure applied is converted into electrical energy, and the coil component 4 and the magnet component 5 output the electrical energy finally generated. These components will be described in detail below.

[0026] Refer to the following Figure 2a-2f The structure of the first friction component 1 of the present invention is described as follows: The first friction component 1 comprises: a belt-shaped fabric composite layer 11; a conductive fabric layer 12; and a loop-shaped fabric composite layer 13.

[0027] In this embodiment, Figure 2a-2c As shown, the first friction component 1 includes a plurality of belt-shaped fabric composite layers 11. Each belt-shaped fabric composite layer 11 has a longitudinal direction (e.g. Figure 2a The plurality of belt-shaped fabric composite layers 11 extend in the width direction (e.g., in the x direction) and Figure 2a The z direction in the figure) is arranged parallel to form a fabric composite layer.

[0028] The belt-shaped fabric composite layer 11 is a fully integrated belt-shaped fabric composite layer formed by chemical crosslinking 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., and the electrode layer can be a conductive fabric material, such as silver cloth or copper-nickel alloy cloth, etc.

[0029] In such Figure 2c In the example shown, the belt-shaped fabric composite layer 11 includes a polymer material layer 111 and an electrode layer 112. At one end of the belt-shaped fabric composite layer 11, the length of the electrode layer 112 is greater than that of the polymer material layer 111, so that a portion of the electrode layer 112 is exposed.

[0030] The conductive fabric layer 12 may be formed of a conductive fabric material of the same or similar type as the electrode layer 112 of the strip-shaped fabric composite layer 11. The conductive fabric layer 12 may be in the form of a strip, and each conductive fabric layer 12 is located between two adjacent stacked strip-shaped fabric composite layers 11, and the three conductive fabric layers 12 form a parallel structure similar to a sandwich layer structure. Figure 2c In the example shown, in the thickness direction ( Figure 2a In the y direction in the figure, a conductive fabric layer 12 is sandwiched between two layers of the strip-shaped fabric composite layers 11. At one end of the strip-shaped conductive fabric layer 12 in the length direction, its length is greater than the length of the strip-shaped fabric composite layer 11 covering the conductive fabric layer 12, so that a portion of the conductive fabric layer 12 is not covered by the strip-shaped fabric composite layer 11 and is exposed, and the exposed portion of the conductive fabric layer 12 is in contact with the exposed portion of the electrode layer 112 in the thickness direction (appendix 1). Figure 2a relative to the y direction in the figure.

[0031] The looped fabric composite layer 13 can be formed of the same or similar material / structure as the strip-shaped fabric composite layer 11. For example, the looped fabric composite layer 13 is formed using the same material as the strip-shaped fabric composite layer 11, and includes a polymer material layer 131 and an electrode layer 132 that are respectively the same as the polymer material layer 111 and the electrode layer 112 of the strip-shaped fabric composite layer 11. The polymer material layer 131 covers a portion of the electrode layer 132, and the uncovered electrode layer forms an exposed portion. The looped fabric composite layer 13 forms a loop-shaped structure surrounding the outer side of the strip-shaped fabric composite layer 11 and the conductive fabric layer 12 in the width direction of the strip-shaped fabric composite layer 11 and the conductive fabric layer 12. The number of loops of the loop-shaped structure can be one or more, and the attached embodiment of the present example may be one or more. Figure 2a-2d The number of loops of the loop-shaped fabric composite layer 13 is one layer, but the number of loops can also be multiple. When the number of loops is 2 or more, the loop-shaped fabric 13 is constructed as a loop structure with multiple layers, that is, compared with the attached Figure 2a The loop fabric 13 shown in FIG. has more windings. Figure 2a-2c In the example shown, there are multiple ring-shaped fabric composite layers 13, 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 multiple ring-shaped fabric composite layers 13 in the length direction extend and are connected in the length direction to form a strip electrode layer that is continuous in the length direction. The power-generating cloth of the present invention has an arched (or U-shaped) structure, and the arched (U-shaped) structure will be described exemplarily below. The strip-shaped fabric composite layer 11 and the conductive fabric layer 12 are stacked to form a strip structure in the thickness direction. The multiple strip structures are arranged side by side in the width direction, i.e., the z direction. At the same time, the electrical connection between each row is achieved through the electrode layer 112 and the conductive fabric layer 12 in the z direction to achieve structural fixation and circuit continuity, forming a planar power-generating cloth body. Among them, the electrical connection refers to the positive and negative electrode layers in the power-generating cloth, and the electrode layers of the same pole are connected to each other by means such as bonding. The power-generating cloth body is connected along the width direction (e.g. Figure 2a The axis on the z direction in the figure is bent (or folded) upward to form a Figure 2b The arched or U-shaped structure shown. The arched (U-shaped) structure is not only a part of the fabric self-rebound structure of the power generation cloth body, but also forms a double-electrode contact friction power generation structure, which effectively improves the output electrical performance of friction power generation, and has stable power generation capacity and good fatigue resistance. Figure 2a-2c In the example shown, the power generating cloth is bent once to form an arched structure. However, the present invention is not limited thereto, and the power generating cloth can also be folded multiple times to form a multi-layer structure. For example, when the power generating cloth is bent twice, the power generating cloth forms a "Z"-shaped folded structure when viewed from the side, that is, a multi-layer structure formed by stacking layers of U-shaped / arched structures.

[0032] The present invention provides an innovative composite weaving method, namely, a plurality of looped fabric composite layers 13 are respectively wrapped around the outside of the strip structure formed by the belt-shaped fabric composite layer 11 and the conductive fabric layer 12, and are symmetrically or staggeredly arranged on the two sides of the arch structure to form a power generation cloth body of the woven structure.

[0033] The following is an exemplary description of the circuit connection method in the power generation cloth. The electrode layer 112 of one (or more) fabric composite layers 11 and the electrode layer 132 in multiple ring-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 achieve circuit continuity. Among them, the electrical connection refers to the positive and negative electrode layers in the power generation cloth, and the electrode layers of the same pole are connected to each other by methods such as bonding.

[0034] In the above Figure 2a-2d middle, Figure 2a This is a schematic diagram from the front. Figure 2b For the opposite side, that is, Figure 2a Schematic diagram looking in the opposite direction. Figure 2c Perspective and Figure 2b The same perspective. Figure 2c The electrical connection method of each layer of the power generation cloth is illustrated. Figure 2c As shown, in this example, the rows of the strip-shaped conductive fabric layer 12 are connected to each other by bonding or other methods. At the same time, the rows of the electrode layer 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 ring-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 as follows Figure 2a As shown. Figure 2e The schematic diagram of the structure of the power generation cloth with one layer of power generation cloth is shown as an example. Figure 2f The schematic diagram of the structure of the power generation cloth with two layers of power generation cloth is shown as an example. Figure 2g The schematic structural diagram of a power generation cloth having three layers is illustrated.

[0035] The power generation cloth in the present invention is a full fabric structure, wherein the belt-shaped fabric composite layer 11, the conductive fabric layer 12 and the loop-shaped fabric composite layer 13 form a fully integrated full fabric structure through the innovative composite weaving method provided by the present invention. The fabric structure has high power generation capacity and has excellent properties of high elasticity, high flexibility, high flame retardancy and washability.

[0036] The following will be combined with the attached Figure 3a and 3b An example of the second friction assembly 2 of the present invention will be described.

[0037] The second friction component 2 includes the polymer material layer 21, the electrode layer 22 and the non-conductive fabric 23. The polymer material layer 21 is completely cross-linked and covers the surface of the electrode layer 22, and is integrated with the non-conductive fabric 23 in a chemically cross-linked manner. The non-conductive fabric 23 is a knitted fabric, a woven fabric or a 3D spacer fabric, or a fabric whose material is conducive to chemical cross-linking. The polymer material layer 21 can be a high molecular polymer material, such as polydimethylsiloxane, barium titanate-doped polydimethylsiloxane, polytetrafluoroethylene, polyvinyl chloride or fluororubber. 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 using a flame retardant.

[0038] The power-generating cloth of the present invention may further include an anti-skid bottom layer 3, which covers the bottom surface of the power-generating cloth body. The material of the anti-skid bottom layer is woven fabric or knitted fabric.

[0039] The power generating cloth of the present invention may also include at least one set of electromagnetic generator components. Figure 4a-4cIn the figure, a structure 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 assembly 2 is a fabric outer layer, which completely covers the upper surface of the power generation fabric body, that is, it is fixed on the upper surface of one or more groups of coil assemblies 4, and the anti-slip bottom layer 3 covers the bottom surface of the power generation fabric body, that is, it is fixed on the lower surface of the magnet assembly 5. In the attached Figure 4a-4c In order to more clearly reflect the structure of the generator, the first friction assembly 1 between the coil assembly 4 and the magnet assembly 5, the second friction assembly on the coil assembly 4 and the anti-slip bottom layer under the magnet assembly 5 are omitted.

[0040] The coil assembly 4 may include at least one of the following: a coil assembly 41, a coil embroidery fabric 42, and a coil woven fabric 43. The coil assembly 41 is, for example, formed by winding an enameled copper wire around the central axis to form a three-dimensional cylinder with a hollow interior, the coil woven fabric 42 is, for example, formed by embroidery of the enameled copper wire and an embroidery non-woven fabric; the coil embroidery fabric 43 is, for example, formed by woven enameled copper wire and ordinary yarn.

[0041] The material of the magnet assembly 5 can be a soft magnet, such as a flexible rubber magnet. The magnet assembly 5 includes a plurality of soft magnets of different polarities, which are alternately arranged in the axial direction. The magnetic properties of adjacent soft magnets are different and attract each other to form the magnet assembly 5.

[0042] The working principle of the power generation cloth of the present invention is described below. The contact parts of the first friction component 1 and the second friction component 2 have different friction electrode sequences. When the power generation cloth is subjected to pressure, the first friction component 1 and the second friction component 2 are in contact; when the pressure on the power generation cloth disappears, the first friction component 1 realizes elastic recovery of the power generation cloth, and the first friction component 1 and the second friction component 2 are separated from each other; during the contact and separation process in the power generation cloth body, the coil component 4 reciprocates along the vertical line of the power generation cloth body under the interaction of the pressure on the power generation cloth body and the elastic force generated by the first friction component 1, so that the coil component 4 cuts the magnetic flux lines of the magnet component 5, thereby generating electricity.

[0043] The above is an example of the structure 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. 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 ring fabric composite layer 13 of the first friction component. Among them, the electrical performance includes 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 ratio of the product of the number of turns of the ring fabric composite layer and the number of the ring fabric composite layers per unit area to the product of the number of layers of the belt fabric composite layer and the surface area of ​​the first friction component. When Y is used to represent the size of the power generation factor, it can be expressed by the following formula (1).

[0044] Y=BC / (A·D) Formula (1)

[0045] The parameters in the above formula (1) represent the following parameters respectively.

[0046] A: The dimensionless number of layers of the first fabric composite layer 11, i.e., the number of layers forming an arched or U-shaped structure. The number of layers refers to the number of parallel folded layers in the first fabric layer 11 that can be woven by the looped fabric composite layer 13 in the vertical direction of the power generation cloth. Figure 2e-2g ,in Figure 2e Indicates 1st floor, Figure 2f Indicates 2 layers, Figure 2g Indicates 3 layers.

[0047] B: The number of turns of the dimensionless loop fabric 13, i.e., the number of turns of the single loop fabric composite layer 13 woven along the periphery of the strip formed by the first fabric composite layer 11 and the electrode layer 12 to form a loop structure. Figure 2a-2c In the example shown in FIG. 1 , the number of turns is 3.

[0048] C: the number of dimensionless third loop fabrics 13, that is, the total number of loop fabric composite layers 13 in the power generation fabric body within a unit area. The unit area can be defined by oneself, such as per square centimeter, per square meter, etc.

[0049] D: dimensionless surface area of ​​the first friction component 1. The surface area D refers to the upper surface area of ​​the entire power-generating cloth, excluding the exposed electrode layer area, that is, the effective area of ​​the power-generating cloth for friction power generation.

[0050] 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.

[0051] Example 1:

[0052] Invention Figure 2e Take the power generating cloth in as an example.

[0053] The number of layers of the arch structure is 1, that is, after dimensionless data processing, A=0.2582. The dimensionless data processing method mentioned in this article is to horizontally normalize the parameters in the experimental data.

[0054] The number of loops of the loop fabric 13 is 3, that is, after dimensionless data processing, B=0.6255.

[0055] The number of loop fabrics 13 is 9, so after dimensionless data processing, C = 0.2694

[0056] The effective surface area of ​​frictional 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, so after dimensionless data processing, D=0.4450.

[0057] The power generation factor in Example 1 is about 0.2905 according to Y=BC / (A·D) in the dimensionless case. Under the test condition of a person walking, the open circuit voltage, short circuit current and energy density generated by the power generation fabric are 363.0V, 6.63μA and 75.21mW·cm -2 .

[0058] Example 2:

[0059] Invention Figure 2f Take the power generating cloth as an example.

[0060] The number of layers of the arch structure is 2, and after dimensionless data processing, A=0.5164.

[0061] The number of loops of the loop fabric 13 is 2, and after dimensionless data processing, B=0.4170.

[0062] The number of the loop fabrics 13 is 15, and after dimensionless data processing, C=0.4490.

[0063] The effective surface area of ​​frictional 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.

[0064] At this time, the power generation factor, according to Y=BC / (A·D), is about 0.1517 in the dimensionless case. Under the test condition 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 .

[0065] The following will be combined with the attached Figure 5To illustrate the power generation factors in this embodiment.

[0066] like Figure 5 As shown, "BC" represents the product of the number of loops of the loop fabric composite layer 13 and the number of loop fabric composite layers 13 after dimensionless conversion. "(A·D)" represents the product of the number of layers of the belt fabric composite layer 11 and the surface area of ​​the first friction component 1 after dimensionless conversion. Figure 5 The horizontal axis represents the ratio of the product of the number of loops of the looped fabric composite layer 13 and the number of looped 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 dimensionless conversion. The vertical axis represents the output energy density of the power generation cloth based on friction power generation. The present invention takes the energy density per unit area as an example. Figure 5 It can be seen that by changing the number of circles of the looped fabric composite layer 13 and the number of looped fabric composite layers 13, that is, the value of "BC", and when the number of layers of different belt-shaped fabric composite layers 11 and the surface area of ​​the first friction component 1 is multiplied, that is, changing the value of "(A·D)", the output energy density of the power generation cloth can be changed. As "BC / (A·D)" increases, the energy density of its 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 is 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 higher.

[0067] The present invention proposes a power generation cloth based on friction power generation through structural design and material selection. The power generation cloth has good elasticity and flexibility, can convert various mechanical energy into electrical energy, and has improved conversion efficiency, reducing resource waste to a certain extent.

[0068] The following is an exemplary description of the method for making the above-mentioned power generating cloth. The various steps in the method are only for illustration and are not intended to limit the method to the steps described. Among the steps of the method, some steps can be omitted and some steps can be replaced by other steps not listed, and the serial numbers of the steps are only for distinguishing the steps, but do not limit the order of the steps.

[0069] 1. Forming an uncrosslinked layer of polymer material.

[0070] A non-crosslinked layer of polymer material in a fluid state is coated on the surface of the first template, and the thickness is controlled by a scraping method to obtain a non-crosslinked layer of polymer material with a certain width, length and thickness. The first template can be a stainless steel plate, a metal plate or a glass plate with a smooth surface. The length and thickness of the polymer material can be controlled by the scraping method.

[0071] 2. Bubble treatment

[0072] The first template coated with the uncrosslinked layer of polymer material is placed in a vacuum box for vacuum degassing. For example, the uncrosslinked layer of polymer material is vacuumed by a vacuum pump until there are no bubbles at all.
