Description

Technical Field

[0001] This invention relates to the field of camouflage robot technology, and in particular to an amphibious multifunctional device with color-changing camouflage and its manufacturing method. Background Technology

[0002] Camouflage robots can hide in their environment and secretly perform tasks such as infiltration and intelligence gathering. Camouflage capability is considered a key factor driving the application of intelligent devices in robotics. This camouflage capability is particularly important in the context of amphibious camouflage robots, as they need to adapt to different environments and perform various tasks. Traditional camouflage robots are typically only usable in a single environment, limiting their operational scope and preventing them from performing tasks in more complex hydrological environments.

[0003] Currently, there is a lack of amphibious camouflage robots with excellent camouflage effects and the ability to adaptively switch between operating modes in water and on land. This invention addresses the specific needs of amphibious environments and the problems existing with current camouflage robots. Summary of the Invention

[0004] The purpose of this invention is to provide an amphibious multifunctional device with color-changing camouflage and its manufacturing method, which can be driven on water and land, and can change color to achieve active camouflage in the environment.

[0005] The technical solution adopted in this invention is: A color-changing camouflage amphibious multifunctional device includes a fuel layer and a carrier layer. The fuel layer covers part of the upper surface of the carrier layer, and one end of the fuel layer extends out of one end of the carrier layer and is suspended in the air. The fuel layer is formed by a mixture of thermochromic dyes and materials with rapid disassembly characteristics. When the materials with rapid disassembly characteristics of the fuel layer dissolve in water, the fuel layer generates propulsion on the water surface due to the Marangoni effect. The fuel layer absorbs light energy and converts it into heat, which is then transferred to the carrier layer, causing the entire multifunctional device to heat up. The carrier layer and the fuel layer have different coefficients of thermal expansion. When the entire multifunctional device heats up, the fuel layer loses water and shrinks, while the carrier layer expands due to heat, causing the multifunctional device to bend towards the fuel layer. At the same time, when the temperature exceeds the first color-changing temperature, the fuel layer undergoes a first color change, changing its color from the first color to the second color and maintaining the second color. When the temperature is below the second color-changing temperature, the fuel layer undergoes a second color change, changing its color from the second color to the first color and maintaining the first color.

[0006] Furthermore, both the fuel layer and the carrier layer are formed using flexible materials.

[0007] Furthermore, the carrier layer has a rectangular structure, and the fuel layer has a rectangular structure; Furthermore, in one feasible embodiment, the fuel layer has a smaller area than the carrier layer and extends beyond the carrier layer only at one end.

[0008] Furthermore, in one feasible embodiment, the carrier layer comprises biaxially oriented polypropylene.

[0009] Furthermore, in one feasible embodiment, the material with rapid disassembly and assembly characteristics is bone glue, which accounts for 20% of the total mass of the fuel layer.

[0010] Furthermore, the first color change temperature is 65℃, and the second color change temperature is -10℃.

[0011] Furthermore, the first color of the fuel layer is blue, and the second color is white; the carrier layer is transparent and colorless.

[0012] A method for manufacturing an amphibious multifunctional device for color-changing camouflage, comprising the following steps: S1, fabricate the carrier layer; S2 utilizes thermochromic dyes and materials with rapid disassembly and assembly characteristics to fabricate the fuel layer, while meeting the requirement that the thermal expansion coefficients of the carrier layer and the fuel layer are different. S3, after cutting the fuel layer and carrier layer to the specified size, the fuel layer is installed on part of the upper surface of the carrier layer, and one side of the fuel layer extends and extends to one side of the carrier layer in a suspended state, thus forming a color-changing camouflage amphibious multifunctional device.

[0013] Furthermore, the specific steps for creating the carrier layer in S1 include: S11 provides biaxially oriented polypropylene film; S12, the biaxially oriented polypropylene film is cut into a set size and shape, which is the carrier layer.

[0014] Furthermore, the specific steps for creating the fuel layer in S2 include: S21 provides material particles with rapid disassembly and assembly characteristics and thermochromic dye solutions; S22, add material particles with rapid disassembly and assembly characteristics into a beaker containing deionized water, and stir magnetically at 50°C for one hour to obtain the first solution; S23, after the first solution is cooled, a thermochromic dye solution is added to the first solution, and the mixture is magnetically stirred at 25°C for one hour to obtain a mixed fuel solution; S24, then invert the well-stirred fuel solution onto the substrate. After the water evaporates, the fuel solution self-assembles into a solid film, which is the fuel layer.

[0015] This invention employs the above technical solutions to construct a solid fuel with color-changing and amphibious driving capabilities, solving the problems of color-changing camouflage and amphibious use. Using biaxially oriented polypropylene film as a substrate, this invention composites the solid fuel with it in a layered manner to prepare a programmable color-changing camouflage amphibious multifunctional robotic device. This robotic device can be driven on both water and land, and can also change color to achieve active camouflage in the environment. Attached Figure Description

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0018] like Figures 1 to 5 As shown in one example, the present invention discloses an amphibious multifunctional device for color-changing camouflage, which includes a fuel layer and a carrier layer. The fuel layer covers part of the upper surface of the carrier layer, and one end of the fuel layer extends out of one end of the carrier layer and is suspended in the air. The fuel layer is formed by a mixture of thermochromic dyes and materials with rapid disassembly characteristics. When the materials with rapid disassembly characteristics of the fuel layer dissolve in water, the fuel layer generates propulsion on the water surface due to the Marangoni effect. The fuel layer absorbs light energy and converts it into heat, which is then transferred to the carrier layer, causing the entire multifunctional device to heat up. The carrier layer and the fuel layer have different coefficients of thermal expansion. When the entire multifunctional device heats up, the fuel layer loses water and shrinks, while the carrier layer expands due to heat, causing the multifunctional device to bend towards the fuel layer. At the same time, when the temperature exceeds the first color-changing temperature, the fuel layer undergoes a first color change, changing its color from the first color to the second color and maintaining the second color. When the temperature is below the second color-changing temperature, the fuel layer undergoes a second color change, changing its color from the second color to the first color and maintaining the first color.

[0019] Furthermore, both the fuel layer and the carrier layer are formed using flexible materials.

[0020] Furthermore, the carrier layer has a rectangular structure, and the fuel layer has a rectangular structure; Furthermore, in one feasible embodiment, the fuel layer has a smaller area than the carrier layer and extends beyond the carrier layer only at one end.

[0021] Furthermore, in one feasible embodiment, the carrier layer comprises biaxially oriented polypropylene.

[0022] Furthermore, in one feasible embodiment, the material with rapid disassembly and assembly characteristics is bone glue, which accounts for 20% of the total mass of the fuel layer.

[0023] Furthermore, the first color change temperature is 65℃, and the second color change temperature is -10℃.

[0024] Furthermore, the first color of the fuel layer is blue, and the second color is white; the carrier layer is transparent and colorless.

[0025] A method for manufacturing an amphibious multifunctional device for color-changing camouflage, comprising the following steps: S1, fabricate the carrier layer; S2 utilizes thermochromic dyes and materials with rapid disassembly and assembly characteristics to fabricate the fuel layer, while meeting the requirement that the thermal expansion coefficients of the carrier layer and the fuel layer are different. S3, after cutting the fuel layer and carrier layer to the specified size, the fuel layer is installed on part of the upper surface of the carrier layer, and one side of the fuel layer extends and extends to one side of the carrier layer in a suspended state, thus forming a color-changing camouflage amphibious multifunctional device.

[0026] Furthermore, the specific steps for creating the carrier layer in S1 include: S11 provides biaxially oriented polypropylene film; S12, the biaxially oriented polypropylene film is cut to a set size to form the carrier layer.

[0027] Furthermore, the specific steps for creating the fuel layer in S2 include: S21 provides material particles with rapid disassembly and assembly characteristics and thermochromic dye solutions; S22, add material particles with rapid disassembly and assembly characteristics into a beaker containing deionized water, and stir magnetically at 50°C for one hour to obtain the first solution; S23, after the first solution is cooled, a thermochromic dye solution is added to the first solution, and the mixture is magnetically stirred at 25°C for one hour to obtain a mixed fuel solution; S24, then invert the well-stirred fuel solution onto the substrate. After the water evaporates, the fuel solution self-assembles into a solid film, which is the fuel layer.

[0028] The specific principles of this invention will be explained in detail below: like Figure 1 The image shows a side view of a color-changing camouflage amphibious multifunctional device 10 according to the present invention. The multifunctional device includes a carrier layer 100 and a fuel layer 200. The fuel layer 200 is located on the surface of the carrier layer 100. A portion of the fuel layer 200 is inside the carrier layer 100 and connected to it, while another portion is located outside the carrier layer 100 and is suspended in mid-air.

[0029] Please see Figure 2 This is a top view of an amphibious multifunctional device 10 according to an embodiment of the present invention. The carrier layer 100 has a rectangular structure. The fuel layer 200 is also rectangular, narrower than the carrier layer 100, and its long side extends beyond the carrier layer 100 only on one side. Most of the area of ​​the fuel layer 200 is attached to the surface of the carrier layer 100, while a small portion is not in contact with the carrier layer 100. The portion of the fuel layer 200 attached to the surface of the carrier layer 100, together with the carrier layer 100, produces a land-driven deformation effect, while the suspended portion of the fuel layer 200 produces a water-driven effect. The two parts are isolated and independent of each other, so that the color-changing camouflage amphibious multifunctional device 10 does not interfere with each other when working on the water and land, realizing the switching of working modes in an amphibious environment.

[0030] Please see Figure 3 The carrier layer 100 and the fuel layer 200 have different coefficients of thermal expansion. Therefore, when the fuel layer 200 absorbs light energy and converts it into heat, it is transferred to the carrier layer 100, causing the entire multifunctional device 10 to heat up. The heated fuel layer 200 loses water and contracts, while the carrier layer 100 expands due to the heat. Because the fuel layer and carrier layer are tightly bonded, under stress, the multifunctional device 10 bends towards the fuel layer 200, achieving a land-driven deformation effect. When the temperature drops, the multifunctional device 10 returns to its initial state.

[0031] The amphibious multifunctional device 10 provided in this embodiment of the invention has a fuel layer containing bone glue that has the characteristic of rapid disassembly and assembly, and can dissolve quickly in water. Therefore, the fuel layer 200 can generate propulsion on the water surface due to the Marangoni effect, driving the color-changing camouflage amphibious multifunctional device 10 to rapidly self-propel itself on the water surface, achieving a water surface driving effect.

[0032] The aforementioned color-changing camouflage amphibious multifunctional device 10 possesses both swimming and propulsion capabilities, thus enabling its use and operation in amphibious environments without further encapsulation or modification. The position and size of the fuel layer 200 are not fixed and can be adjusted as needed, enabling the programmable design and driving mode of the color-changing camouflage amphibious multifunctional device 10.

[0033] The carrier layer 100 is transparent and colorless, and the color of the color-changing camouflage multifunctional device depends on the color of the fuel layer 200. See also... Figure 4 The thermochromic dye in the fuel layer 200 gives it the ability to change color. The fuel layer 200 is blue under normal conditions, turns white when heated to 65°C and remains so, and turns back to blue when cooled to -10°C and remains so.

[0034] Please see Figure 5 The fuel layer 200 is composed of thermochromic capsule particles 220 encapsulated in bone glue 210 at a microscopic level.

[0035] The aforementioned color-changing camouflage amphibious multifunctional device 10 is an integrated unit, characterized by its compact size and lightweight design. It can camouflage itself in blue-white environments by changing color and can adaptively switch between operating modes on water and in air. The entire device is constructed of flexible materials, has no mechanical wear during operation, and can be used multiple times.

[0036] This invention also provides a method for manufacturing a color-changing camouflage amphibious multifunctional device 10, the color-changing camouflage amphibious multifunctional device 10 including a carrier layer 100 and a fuel layer 200, the manufacturing method including: S10, fabricate the carrier layer 100.

[0037] S2, the fuel layer 200 is fabricated.

[0038] S3, the fuel layer 200 is installed on the surface of the carrier layer 100, and extends out of the carrier layer 100 on only one side to form a color-changing camouflage amphibious multifunctional device 10.

[0039] In S1, the method for fabricating the carrier layer 100 includes: S11 provides biaxially oriented polypropylene film.

[0040] S12, the film is cut into a rectangle of a certain size, which is the carrier layer 100.

[0041] In S2, the method for fabricating the fuel layer 200 includes: S21 provides bone glue granules and thermochromic dye solution; S22, the particles are added to a beaker containing deionized water and magnetically stirred at 50°C for one hour; S23, after the obtained bone glue solution is cooled, a thermochromic dye solution is added to it and magnetically stirred at 25°C for one hour; S24, then invert the well-stirred mixed fuel solution onto the substrate. After the water evaporates, the fuel solution self-assembles into a solid film, which is the fuel layer 200.

[0042] This invention employs the above technical solutions to construct a solid fuel with color-changing and amphibious driving capabilities, solving the problems of color-changing camouflage and amphibious use. Using biaxially oriented polypropylene film as a substrate, this invention composites the solid fuel with it in a layered manner to prepare a programmable color-changing camouflage amphibious multifunctional robotic device. This robotic device can be driven on both water and land, and can also change color to achieve active camouflage in the environment.
