Description

Technical Field

[0001] This invention belongs to the field of protective equipment and the interdisciplinary technology of optical and electric field control. Specifically, it relates to a composite protective system with customizable materials for different scenarios, independent and synergistically controllable optical and electric dual-field parameters, and an outer mesoscopic particle gradient protection system plus an optional inner rigid bottom-layer protective layer. This system can flexibly adapt to transparent scenarios (goggles, laser-proof goggles, windows of photoelectric detection equipment, aircraft observation windows) and non-transparent scenarios (personal protective equipment, special protective vehicle bodies, precision instrument shells). Through customized selection of core materials before leaving the factory and precise control of optical and electric dual fields, it achieves multi-functional integration of physical impact protection, laser energy attenuation, electromagnetic signal shielding, and self-healing protective layer. It is particularly suitable for high-end protective equipment, civilian protection, and precision instrument protection fields with stringent requirements for protective performance, scenario adaptability, and transparency. Background Technology

[0002] Existing protective equipment faces numerous technical bottlenecks in practical applications, making it difficult to meet the diverse and multifunctional needs of modern protection: • Poor scene adaptability: The core material selection of traditional protective equipment is fixed and cannot be flexibly adapted to different scene requirements such as transparent / non-transparent, lightweight / high strength, etc. This results in a lack of laser and electromagnetic protection functions in transparent scenes, and problems such as single function and excessive weight in non-transparent scenes. • Transparency and protection are difficult to achieve simultaneously: The rigid bottom layer of most composite protection systems affects light transmittance and cannot be applied to transparent scenarios such as photoelectric windows, while purely transparent protective equipment only has basic protection capabilities and lacks core protection functions such as laser, electromagnetic, and impact resistance. • Insufficient synergy between photoelectric control: Existing photoelectric composite protection systems cannot achieve independent control of all parameters of the optical field and electric field, making it difficult to accurately adapt to the protection needs of different types of impact threats, resulting in low protection efficiency and accuracy; • Single-function protection system: Traditional protective equipment focuses on a single protective function and lacks a composite protection architecture that integrates physical protection, laser attenuation, electromagnetic shielding and self-healing, making it unable to cope with multiple types of threats in complex scenarios; • High risk of secondary damage: Some protective equipment is prone to problems such as embedding of penetrating objects and secondary splashing after resisting impact, and the protective layer has no self-healing ability, resulting in high cost and low reliability.

[0003] Among existing protection technologies, there is no technical solution that combines customized selection of core materials for different scenarios, full control of optical and electrical dual-field parameters, and optional bottom layer design, making it difficult to simultaneously meet the differentiated protection needs of multiple scenarios. Summary of the Invention

[0004] Overview of core technology principles The core technical principle of this invention is based on the synergistic confinement effect of optical and electric dual fields, the dynamic control of mesoscopic particles, and the multi-field coupling protection mechanism. Through the precise coordination of optical field gradient force and electric field polarization force, the dynamic response of the mesoscopic particle array, and the hierarchical adaptation of the gradient structure, an integrated "confinement-dissipation-protection" technical system is constructed. This system simultaneously achieves kinetic energy impact protection, electromagnetic signal shielding, and laser energy attenuation within a single structure. The specific principles are as follows: 1. Optical-Electrical Dual-Field Cooperative Binding and Particle Stabilization Mechanism The optical field control module constructs a micrometer-scale three-dimensional optical cage array (with the optical cage side length precisely matched to the mesoscopic particle diameter in a 1:1 ratio) using multi-wavelength laser interferometry and spatial light modulation technology. It utilizes optical gradient forces to form a potential energy trap, achieving non-mechanical contact suspension and positioning of mesoscopic particles with a confinement accuracy of ±0.1μm. The electric field control module applies an alternating electric field, causing the mesoscopic particles to generate a polarization response and induced charges on the particle surface. Coulomb repulsion counteracts the particle aggregation tendency, while simultaneously forming a synergistic constraint with the optical field potential energy trap, ensuring a uniform particle distribution under normal conditions and an impact-resistant particle spillage rate ≤1%. The dual-field coordination employs SPI bus synchronous control with a response delay ≤0.001s. Dual-channel PWM control signals are output through an FPGA chip to achieve independent adjustment and coordinated adaptation of field strength, wavelength / frequency, ensuring stable particle arrangement under both static standby and dynamic impact scenarios.

[0005] 2. Impact kinetic energy dissipation in multiple stages and directional protection mechanism When an external impact occurs, the impact sensing and identification unit (sensor array density 10 units / cm²) quickly captures the impact velocity, acceleration, and stiffness parameters. The central core control module determines the threat level in real time and triggers the corresponding protection strategy. • Low-speed threat (≤50m / s): The dual fields maintain low-intensity cooperative constraint. Mesoscopic particles generate perturbation motion under the flexible constraint of optical-electric dual fields. The impact time is extended by inter-particle friction damping and gradient structure deformation buffering. The directional kinetic energy is converted into thermal energy and particle vibration energy, and the backward transmission effect of the impact is greatly reduced. • Medium- and high-speed threats (>50m / s): The electric field is instantly boosted to 90%-95% of the instantaneous withstand pressure of the medium within 1ms, the optical field switches to pulsed high-power mode, and the particles are bound into a rigid lattice structure. Through particle compression, penetrator deformation and the layer-by-layer dissipation of gradient field strength, kinetic energy is rapidly dissipated and penetration is blocked. • Post-impact stage: The dual-field synergistic output of 3-5kV / cm reverse field strength, the combined force of optical gradient force and electric field repulsion drives the mesoscopic particles to return to their original positions (return time ≤0.005s), while the penetrator / fragment with zero kinetic energy is ejected from the protective layer to avoid embedding and secondary splashing. The protective layer completes self-repair through particle rearrangement and field reconstruction, and its performance after repair is consistent with the initial state.

[0006] 3. Multifunctional Coupling Protection Mechanism This invention achieves multifunctional coupling of physical protection, electromagnetic shielding, and laser attenuation through structural integration and material adaptation. • Electromagnetic shielding: Mesoscopic particles (Fe3O4 magnetic loss composite particles, TiO2 high dielectric microspheres, etc.) and high dielectric filling medium form a broadband loss system covering the 2-40GHz electromagnetic band. The dynamic optical-electric dual field can disrupt the radar echo phase and achieve spatial dispersion. The photopolarization layer forms an equivalent electromagnetic shielding interface, which together achieves a shielding effectiveness of 25-70dB. • Laser attenuation: Mesoscopic particles have a dual effect of scattering and absorbing lasers in the 200-1500nm band. The light field control module can adjust the density of the optical cage array to enhance the scattering effect. The laser extinction ratio is ≥85% in transparent scenes and ≥99% in non-transparent scenes. The laser energy is absorbed and converted into heat energy through particle energy level transitions, avoiding laser penetration and damage to internal components. • Energy self-sufficiency: The energy capture and reinjection module converts impact kinetic energy and particle displacement energy into usable energy of the system through piezoelectric / photoelectric energy capture units (capture efficiency ≥85%), and reinjects the photoelectric control module to achieve energy balance between normal low-power standby (optical field power consumption <0.5W, electric field leakage current <1μA / cm²) and impact transient high-power output.

[0007] 4. Scene-specific material adaptation and structural coordination mechanism The core materials adopt a customized selection mode before leaving the factory, and are precisely adapted to the performance requirements of transparent / non-transparent scenarios: for transparent scenarios, ITO transparent nanoelectrodes (transmittance ≥85%) and high-transmittance PMMA / TiO2 mesoscopic particles and fluorosilicone composite gel (transmittance ≥85%) are selected to ensure both light transmittance and protective performance; for non-transparent high-strength scenarios, metal mesh electrodes (conduction efficiency ≥98%), SiC / ZrO2 high-hardness ceramic microspheres and nano high-voltage insulating gel (breakdown field strength ≥60kV / mm) are selected to improve rigid protection and energy dissipation capabilities. The outer protection system adopts a cyclic stacking structure of "1mm thin constraint layer + 2mm medium damping layer + 3mm high rigidity layer + 4mm gradient transition layer". A 0.2mm insulating isolation layer is set between the layers to avoid field interference. The total thickness is designed to be 5cm (electromagnetic / transparent specialized type) or 8cm (mechanical specialized type) depending on the scenario. An optional inner rigid bottom protection layer (3-5mm) is only installed in non-transparent scenarios. The outer and inner layers achieve synergistic protection through a flexible buffer layer, which completely solves the problem of excessive impact transmission of traditional rigid protection.

[0008] Purpose of the invention This invention addresses the aforementioned deficiencies of existing technologies by providing a scenario-specific customized transparent / non-transparent optical-electric dual-field synergistic composite protection system. Its core objective is: 1. Enable customized selection of core materials for different scenarios before leaving the factory, solving the problems of insufficient protection in transparent scenarios and limited functionality in non-transparent scenarios; 2. The design includes an optional inner rigid bottom protective layer, balancing the need for transparency with the strength of protection against high-speed impact threats; 3.

Construct an outer mesoscopic particle gradient protection system that integrates multiple protection functions and prevents secondary damage; 5. Ensure the feasibility of system engineering and achieve large-scale production based on existing mature technologies and industrially available materials.

[0009] Technical solution A scenario-specific customized transparent / non-transparent optical-electric dual-field synergistic composite protection system is characterized by its integrated structure comprising an outer mesoscopic particle gradient protection system, an optional inner rigid backstop protection layer, an optical field control module, an electric field control module, an impact sensing and identification unit, a central core control module, and an energy capture and reinjection module. All core functional materials are customized and pre-selected according to the application scenario before leaving the factory, eliminating the need for on-site replacement. The optical field control module and the electric field control module are independently controlled by the central core control module, enabling precise adjustment of all parameters and coordinated linkage based on threat type. The outer system is a multi-layered cyclic gradient stacked structure, completing the dissipation of conventional impact threats and multi-functional protection. The inner layer is an optional top-grade rigid protection material, serving only as a final backup against high-speed impact threats. The specific technical solution is as follows: (1) Core materials are customized and selected according to different scenarios (the design is finalized before leaving the factory, and there is no on-site replacement). All core materials are customized and selected for use before leaving the factory based on the protection strength, weight / thickness constraints, light transmittance requirements, and energy consumption needs of transparent / non-transparent scenarios. The selection range, technical parameters, and scenario adaptability of each material are as follows: 1. Mesoscopic particles: • Optional range: PMMA polymer microspheres, TiO2 high dielectric microspheres, SiC / ZrO2 high hardness ceramic microspheres, HfO2 / ZrO2 ultra-high dielectric microspheres, Fe3O4 magnetic loss composite microspheres; • Particle size parameters: 1-50μm (select 1-5μm high-transmittance, low-scattering particles for transparent scenes, and 10-20μm high-hardness, high-loss particles for non-transparent scenes). • Scene adaptation: For transparent scenes such as goggles and windows of photoelectric detection equipment, PMMA microspheres or high-transmittance TiO2 microspheres are selected; for non-transparent scenes such as personal protective equipment and special protective vehicles, SiC / ZrO2 ceramic microspheres + Fe3O4 composite particles are selected; and for precision instrument scenes, low-impact HfO2 microspheres are selected.

[0010] 2.

[0011] 3.

[0012] 4. Light field generating materials: • Optional configurations: near-infrared dot array light source, visible light array light source, multi-wavelength laser interference light source, spatial light modulator; • Key parameters: light field intensity 0.1-10mW / cm², working wavelength 200-1500nm, response time ≤100μs; • Scene adaptation: Select visible light array light source for transparent scenes, near-infrared dot array light source for regular non-transparent scenes, and multi-wavelength laser interference light source for high-intensity protection scenes.

[0013] 5. Optional inner rigid bottom protective material: • Optional materials: Ultra-high strength polyethylene thin film, ultra-light aramid composite material, nano-ceramic thin film, silicon carbide composite armor thin film; • Key parameters: Thickness 3-5mm, tensile strength ≥1500MPa, impact toughness ≥80kJ / m²; • Scene adaptation: Must be installed in non-transparent high-strength scenes, not required in transparent scenes, and ultra-lightweight aramid composite material can be selected for precision instrument scenes.

[0014] Material composite process: When composited with mesoscopic particles and liquid high-dielectric gel precursor, the particles are uniformly dispersed by ultrasonic dispersion at 300W for 10 minutes, and 0.5% KH550 coupling agent is added to avoid particle agglomeration. After composite, room temperature curing (25℃, 24h) or low temperature heating curing (60℃, 4h) is used. After curing, the medium is free of bubbles and the particles are uniformly distributed, which meets the requirements of field control and protection.

[0015] (2) Independent and coordinated control of all parameters of optical-electric dual field The optical field control module and the electric field control module are independently modularly designed. The central core control module enables precise adjustment of all parameters, including field strength, wavelength / frequency, operating mode, and response timing. It can also achieve dual-field coordinated linkage based on the threat signal from the impact sensor identification unit. The overall response delay of the two fields is ≤0.001s, adapting to the protection requirements of different types of impact threats. The optical field / electric field control module and the central core control module are electrically connected via SPI bus. Each module is equipped with an optocoupler isolation circuit to avoid signal interference. The FPGA chip outputs dual-field control commands through two PWM signals to achieve independent output and coordinated linkage.

[0016] 1. All parameters of the light field are controllable: • Intensity adjustment: 0.1-10mW / cm² (0.1-0.5mW / cm² for transparent scenes, 5-10mW / cm² for high-intensity scenes). • Wavelength adjustment: 200-1500nm (ultraviolet band is suitable for photopolarization, visible light is suitable for transparent scenes, and near-infrared is suitable for low-power scenes). • Operating modes: Continuous low-power standby mode, pulsed high-power enhancement mode; • Core Function: Constructs a hexagonal, micron-scale three-dimensional optical cage array using multi-wavelength laser interferometry. Two coherent laser beams are incident at a 60° angle to form an interference field. Combined with phase modulation using a spatial light modulator, the optical cage is formed. The side length of the optical cage is 1-5μm (precisely matched with the particle size of mesoscopic particles), achieving high-precision spatial confinement of mesoscopic particles without mechanical contact. The particle confinement accuracy is ±0.1μm, and the impact-resistant particle spillage rate is ≤1%.

[0017] 2. All parameters of the electric field are controllable: • Strength adjustment: 0-50kV / cm (normal field strength is 20%-30% of the static breakdown field strength of the medium corresponding to the electric field, and is increased to 90%-95% of the instantaneous withstand voltage of the medium during impact). • Operating modes: Normal low field strength standby mode, and impact instantaneous high field strength enhanced mode; • Gradient control: The electric field gradient distribution can be adjusted according to the type of threat to achieve the gradual dissipation of the penetrator's kinetic energy and precise depth control.

[0018] 3. Dual-field collaborative linkage logic: • Low-speed threat: The light field maintains a low intensity, and the electric field maintains a low field strength, working together to achieve flexible particle confinement and gradient energy absorption, thus prolonging the impact time; • Medium and high speed threats: The light field switches to pulsed high power mode, and the electric field instantaneously generates high voltage to the instantaneous withstand voltage of the medium of 90%-95%, which synergistically achieves rigid binding of particles and rapid dissipation of kinetic energy, effectively blocking the intruder; • Post-impact stage: The dual-field synergistic output of 3-5kV / cm reverse field strength, combined with the optical gradient force and electric field repulsion force, drives the mesoscopic particles to return to their original positions, while simultaneously ejecting the penetrator / fragment from the protective layer.

[0019] (3) Outer Mesoscopic Particle Gradient Protection System Structure and Working Mode The outer mesoscopic particle gradient protection system is a multi-layered cyclic gradient stacked structure. The basic cyclic unit consists of a 1mm thin constraint layer, a 2mm medium damping layer, a 3mm high rigidity layer, and a 4mm gradient transition layer. A 0.2mm insulating layer is placed between the layers to prevent field interference. The layers are stacked cyclically according to scenario requirements to the designed total thickness: 5cm for the electromagnetic / transparent specialized type and 8cm for the mechanical specialized type. All layers integrate customized mesoscopic particles, electrode materials, and photoelectric control components to achieve threat-specific adaptive protection and multi-functional integration. The specific operating mode is as follows: 1. Physical protection mode: • Low-speed conventional threats: Allows limited penetration of the penetrator, prolongs the impact time and expands the stress diffusion area through the damping effect of the multi-layer gradient structure, and converts the impact kinetic energy into heat dissipation through particle perturbation, friction and damping, greatly reducing the backward transmission effect of the impact. • Medium- and high-speed threats: Instantaneous high field strength binds particles into a rigid lattice, and the gradient field strength distribution dissipates the kinetic energy of the penetrator layer by layer, achieving effective blocking of the penetrator, with no permanent damage to the protective layer; • Transparent scene adaptation: When there is no inner bottom protective layer, the outer layer system alone can achieve scratch protection, low-speed impact protection, and laser irradiation protection while maintaining high light transmittance, making it fully compatible with scenarios such as goggles and windows of photoelectric detection equipment.

[0020] 2. Multifunctional integrated protection mode: • Laser attenuation: Mesoscopic particles have the ability to scatter and absorb lasers in the 200-1500nm wavelength band. The optical field control module can adjust the density of the optical cage to enhance the scattering effect and achieve effective attenuation of laser energy. • Electromagnetic shielding: Broadband electromagnetic signal shielding is achieved through the broadband dielectric loss of mesoscopic particles, the phase disorder and spatial dispersion of electromagnetic signals by dynamic photoelectric dual fields, and the equivalent electromagnetic shielding of photopolarized layers. • Impact-Return-Ejection-Self-Repair Mechanism: After impact, the central core control module outputs a 3-5kV / cm reverse photoelectric dual field, enabling mesoscopic particles to return to their original positions quickly and orientingly. Simultaneously, the field repulsion force ejects the penetrator / fragment from the protective layer, resulting in no embedded fragments or secondary debris. The energy capture and reinjection module converts the impact kinetic energy and particle displacement energy into usable energy for the system through piezoelectric / photoelectric energy capture units, reinjecting it into the photoelectric control module to achieve energy self-sufficiency. The protective layer can quickly complete full-area repair, and the arrangement accuracy of mesoscopic particles after repair is consistent with the initial state, allowing it to withstand multiple impacts.

[0021] (4) Optional inner rigid bottom protective layer design (not installed in transparent scenes, optional for non-transparent scenes) The inner top-level rigid bottom protective layer is a single-layer dense structure, installed only inside the outer mesoscopic particle gradient protection system in non-transparent, high-intensity scenarios. It is not installed in transparent scenarios to ensure light transmittance. The specific design is as follows: 1. Structural parameters: Thickness 3-5mm, with a 0.5mm flexible buffer layer between the inner and outer layers to avoid interlayer energy reflection and secondary damage, ensuring the overall fit of the double-layer system; 2. Material characteristics: The rigid protective material is customized and selected before leaving the factory, which has high tensile strength, high impact toughness, and low impact transmission characteristics; 3. Working mechanism: It serves only as the ultimate backup against high-speed impact threats outside the outer protective boundary; the outer system can significantly dissipate the kinetic energy of high-speed impact threats, greatly reducing the impact load when the penetrator reaches the inner layer, thus completely solving the problem of excessive impact transmission in traditional rigid protective materials; 4. Service life: All conventional threats are eliminated by the outer layer system, and the inner layer does not participate in conventional protection. There is no fatigue wear or microscopic damage, and the service life is consistent with that of the equipment body, requiring no additional maintenance.

[0022] (5) Impact sensing and identification and central control logic 1. Impact sensing and recognition unit: • Composition: It consists of a piezoelectric thin film sensor and a triaxial accelerometer. The sensor array density is 10 sensors / cm², which are evenly distributed on the surface of the outer protective system. • Performance parameters: Response time < 100μs, velocity recognition range 0.1-1000m / s, acceleration recognition range 1-1000g, stiffness recognition accuracy ±5%; • Core functions: It can accurately identify the speed, acceleration, and stiffness parameters of impact threats, determine the type of impact threat through the algorithm of the central core control module, and the identification threshold can be customized according to the scenario.

[0023] 2. Central core control logic: • Signal processing: The sensing unit transmits the threat signal to the central core control module. The module uses an FPGA chip to achieve high-speed signal processing and completes threat determination within 0.001s. • Control logic: Synchronously control the field strength, working mode and dual-field coordination timing of the light field and electric field according to the threat type. If the inner bottom protection layer is installed under high-speed impact threat, the coordinated response of the inner and outer layers will be triggered. • Self-repair trigger: After impact, the system automatically initiates the return, bounce, and self-repair procedures. Once the repair is complete, the system automatically returns to normal standby mode. No manual intervention is required throughout the process, achieving intelligent and automated protection.
