Description

Technical Field

[0001] This utility model relates to the field of fabric technology, and in particular to a flexible luminescent fluorescent fabric. Background Technology

[0002] Traditional luminescent fabrics generally suffer from poor flexibility, brittle conductive networks, and rapid decay of luminous efficiency. In existing technologies, fluorescent materials are often bonded to fabrics through simple coating or sewing processes, resulting in weak interfacial bonding between the luminescent and conductive layers, leading to delamination during repeated bending. Furthermore, the conductive networks typically employ linear wires, making them ill-suited for complex deformations and lacking modular design. This technology addresses the challenge of synergistically optimizing the electrical stability and optical performance of flexible electronic devices under dynamic deformation by combining a composite structure design of a serpentine conductive component and a flexible interlayer with a dual-mode implementation scheme for the fluorescent luminescent layer. Utility Model Content

[0003] The main objective of this invention is to provide a flexible luminescent fluorescent fabric that can effectively solve the problems in the background technology.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A flexible fluorescent fabric includes a flexible substrate, a fluorescent emitting layer, a conductive network mechanism, and an external encapsulation layer. The top surface of the flexible substrate is connected to the conductive network mechanism, the top surface of the conductive network mechanism is connected to the fluorescent emitting layer, and the top surface of the fluorescent emitting layer is connected to the external encapsulation layer. The conductive network mechanism includes a serpentine conductive component, a main conductor, a first plastic panel, a second plastic panel, and two flexible interlayers. The main conductor is embedded between the flexible substrate and the fluorescent emitting layer. The surface of the main conductor is covered with the second plastic panel. The serpentine conductive component is encapsulated between the two flexible interlayers, and the end of the serpentine conductive component is electrically connected to the first plastic panel.

[0005] Preferably, the joint between the second plastic panel and the first plastic panel is provided with a connecting buckle that cooperates with each other, the connecting buckle including an elastic buckle and a limiting groove structure.

[0006] Preferably, the second plastic panel and the first plastic panel are respectively provided with electrical connection points of corresponding polarity on their mating surfaces, and the electrical connection points form a conductive path when the panels are fastened together.

[0007] Preferably, the fluorescent luminescent layer adopts a mesh structure formed by blending fluorescent fibers and textile fibers, or adopts a composite fabric layer with rare earth-doped zinc sulfide phosphor coated on the surface.

[0008] Preferably, the serpentine conductive component is formed by a three-dimensional weaving process of silver nanowires and carbon fibers to create a serpentine pleated structure, with its extension direction perpendicular to the fabric deformation direction.

[0009] Preferably, it also includes a micro control module integrated into the edge of the fabric, the micro control module comprising a Bluetooth communication chip and a programmable LED driver circuit, which is connected to the main conductor in the conductive network structure via flexible FPC lines.

[0010] Compared with the prior art, the present invention has the following beneficial effects: 1. Excellent flexibility and durability: The serpentine conductive components combined with the flexible sandwich design allow the fabric to maintain its structural integrity when repeatedly bent and folded, significantly improving its fatigue resistance in dynamic use scenarios.

[0011] 2. Stable conductivity: The three-dimensional braided conductive network disperses stress through fold deformation, maintaining a continuous conductive path under tension or torsion, effectively avoiding the risk of breakage of traditional wires.

[0018] like Figure 1-4 As shown, a flexible fluorescent fabric includes a flexible substrate 1, a fluorescent light-emitting layer 2, a conductive network mechanism 3, and an external encapsulation layer 4.

The conductive network mechanism 3 includes a serpentine conductive component 31, a main guide wire 33, a first plastic panel 34, a second plastic panel 35, and two flexible interlayers 32. The main guide wire 33 is embedded between the flexible substrate 1 and the fluorescent light-emitting layer 2. The surface of the main guide wire 33 is covered with the second plastic panel 35. The serpentine conductive component 31 is encapsulated between the two flexible interlayers 32, and the end of the serpentine conductive component 31 is electrically connected to the first plastic panel 34.

[0019] In this embodiment, the joint between the second plastic panel 35 and the first plastic panel 34 is provided with a connecting buckle 36 that cooperates with each other. The connecting buckle 36 includes an elastic buckle and a limiting groove structure. The joint surfaces of the second plastic panel 35 and the first plastic panel 34 are respectively provided with electrical contact points 37 with corresponding polarities. The electrical contact points 37 form a conductive path when the panels are fastened. The serpentine conductive component 31 is formed by silver nanowires and carbon fibers through a three-dimensional weaving process to form a serpentine pleated structure. Its extension direction is perpendicular to the fabric deformation direction. It also includes a micro control module integrated into the edge of the fabric. The micro control module includes a Bluetooth communication chip and a programmable LED driving circuit, which is connected to the main line 33 in the conductive network mechanism 3 through a flexible FPC line.

[0020] Specifically, the serpentine conductive component 31 and the flexible interlayer 32 work together to maintain the integrity of the conductive network structure 3 when the fabric is repeatedly bent, avoiding mechanical damage caused by deformation. The three-dimensionally woven serpentine conductive component 31 absorbs stress through pleat unfolding, ensuring that the conductive network structure 3 maintains a continuous conductive path when stretched or twisted. The combination structure of the connecting buckle 36 and the electrical contact point 37 supports the rapid splicing of the conductive network structure 3, realizing flexible replacement and expansion of functional blocks. The integrated micro control module is connected to the main guide line 33 through flexible FPC lines to realize Bluetooth wireless control of the light emission mode and brightness of the fluorescent light-emitting layer 2.

[0022] Specifically, the fluorescent luminescent layer 2 achieves enhanced luminous efficiency through a blended mesh or phosphor coating, while the light-transmitting design of the outer encapsulation layer 4 ensures uniform light diffusion. The outer encapsulation layer 4 is made of waterproof and weather-resistant material, protecting the fluorescent luminescent layer 2 and the conductive network structure 3 from temperature and humidity changes and external corrosion.

[0023] Working principle: Conductive network drive: The micro control module inputs control signals to the main line 33 through the flexible FPC line, and is coupled to the serpentine conductive component 31 through the connector 36; Fluorescence excitation mechanism: When current flows through the serpentine conductive component 31, a uniform electric field is generated, which activates the rare earth-doped zinc sulfide phosphor or fluorescent fiber in the fluorescent light-emitting layer 2, and photoluminescence is achieved through carrier injection; Deformation adaptability: The extension direction of the serpentine pleated structure 31 is perpendicular to the deformation direction of the fabric. When stretched / bent, the pleats unfold to absorb stress and maintain the integrity of the conductive path; Encapsulation protection: The outer encapsulation layer 4 is made of a light-transmitting polymer material, which protects the fluorescent layer 2 while allowing more than 85% visible light transmittance.

[0024] The preparation method includes the following steps: Substrate treatment: The polyurethane / silicone composite film is hot-pressed into a flexible substrate 1, and the surface is plasma treated to enhance adhesion; Conductive network construction: Silver-copper alloy main lines 33 are embedded on the surface of substrate 1 using 3D printing process, covering the second plastic panel 35; Silver nanowire-carbon fiber hybrid yarn is prepared by electrospinning, and then heat-set by a pleating mold to form a serpentine conductive component 31, which is sandwiched between flexible layers 32 and welded to the first plastic panel 34. Fluorescent layer preparation: Option 1: Eu³⁺ doped fluorescent fibers and polyester fibers are blended in a 1:5 ratio and knitted into a mesh structure. Option 2: Deposit a 50-100μm thick ZnS:Ag⁺ fluorescent powder coating on the surface of the nylon base fabric using a spraying process; Packaging and integration: The fluorescent light-emitting layer 2 is laminated onto the surface of the conductive network structure 3, PDMS is coated to form an external packaging layer 4, and finally the micro control module is integrated at the edge through a reflow soldering process.
