Description

Technical Field

[0001] This invention belongs to the field of protective devices, specifically relating to a flexible anti-drone camouflage. Background Technology

[0002] Unmanned aerial vehicles (UAVs) typically exhibit low observability, low noise, low speed, and low-altitude flight characteristics, making them difficult to detect effectively using traditional detection methods. Their terminal attack phase often employs a dive attack, resulting in an extremely short interception window. These UAVs can carry warheads that detonate upon contact with the target, posing a serious threat to personnel, equipment, and facilities. Furthermore, UAVs are characterized by low cost and scalability, capable of creating saturation attack pressure on traditional defense systems, thereby depleting defense resources. High-value mobile platforms, command nodes, and critical infrastructure are typical targets.

[0003] Currently, in relevant applications, physical barriers such as metal meshes, fences, or supporting structures are often installed on the exterior of the vehicle platform to detonate the drone before it contacts the platform, thus isolating the explosive impact and fragments at a safe distance, achieving the purpose of attenuating damage and protecting internal equipment and personnel. While these simple protective measures can provide some protection, they typically have significant drawbacks such as cluttered appearance, inconvenient installation and disassembly, heavy weight, time-consuming process, incomplete coverage, and impact on platform mobility and normal operation. Therefore, there is an urgent need for a new type of protective device that can overcome these shortcomings. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a flexible anti-drone tarpaulin, which is composed of a flexible base, an array of spikes, a tensioning attachment and a stabilizing device. The flexible tarpaulin can be made to be flexible and rigid through tensioning, and can quickly cover the target and keep the spikes stably upright, thereby forming an effective physical interception of approaching drones.

[0005] This invention provides a flexible anti-drone camouflage, comprising: A flexible substrate that is spread out and used to cover the surface of the target being protected; Multiple spike components are arranged in an array on the flexible substrate, each spike component having a spike protruding from the flexible substrate; Multiple attachments are provided at the edge of the flexible substrate or on the side of the flexible substrate away from the spike, for fixing the flexible drape to the protected target and keeping the flexible substrate in a tensioned state, thereby keeping the spike upright; And a stabilizing device, connected between each of the spikes and the flexible substrate, for limiting the spikes from deviating from the vertical position. Furthermore, the stabilizing device includes: A stabilizing net connects each of the spikes, so that the multiple spikes are interconnected to form a whole; And connecting components, which connect the stabilizing net and the flexible substrate.

[0006] Furthermore, the connecting component is a flexible connector, with its two ends fixedly connected to the stabilizing net and the flexible substrate, respectively.

[0007] Furthermore, the projected area of ​​the flexible substrate on the horizontal plane is larger than the projected area of ​​the stabilizing net; the two ends of the flexible connector are respectively connected to the outer edge of the stabilizing net and the corresponding position of the flexible substrate, so that when the flexible substrate is tensioned by the attachment, the flexible connector pulls the outer edge of the stabilizing net outward, thereby tightening the stabilizing net.

[0008] Furthermore, the stabilizing net is configured such that the connection point between it and each of the spikes is adjustable or preset, allowing the stabilizing net to be selectively tightened at different heights according to the curvature of the surface of the protected target, thereby maintaining the vertical stability of the spikes.

[0009] Furthermore, the spike assembly is detachably mounted on the flexible substrate.

[0010] Furthermore, the spike assembly is mounted on the flexible substrate via a threaded fastening structure; the threaded fastening structure includes a mounting hole on the flexible substrate, a mating portion with internal threads on the spike assembly, and a fastener capable of passing through the mounting hole and being threadedly connected to the mating portion.

[0011] Furthermore, the spike is a hollow thin-walled tube; The tip of the spike is provided with a protective cap with a smooth outline, or the tip of the spike is provided with a forked strip.

[0012] Furthermore, the outer edge of the flexible substrate is provided with splicing members for splicing multiple flexible drapes together to expand the coverage area.

[0013] Furthermore, the splicing component includes a first connecting portion disposed on one edge of the flexible substrate and a second connecting portion disposed on the other edge, which cooperates with the first connecting portion.

[0014] The beneficial effects of this invention are that the flexible anti-drone camouflage provides an anti-drone solution that combines all-around protection, rapid and convenient deployment, good adaptability, and high dynamic reliability. It successfully transforms a lightweight and flexible camouflage form into a robust and stable three-dimensional interception system, effectively countering the threat of low-cost drones and significantly improving the survivability of high-value targets.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0017] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0018] Furthermore, in this invention, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0019] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection, an electrical connection, a physical connection, or a wireless communication connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two elements or the interaction between two elements, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0020] Furthermore, the technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are feasible for those skilled in the art. If the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.

[0021] like Figures 1-2 As shown, the present invention provides a flexible anti-drone camouflage system, comprising: The flexible substrate 1 is spread out and used to cover the surface of the protected target. The flexible substrate 1 can be spread out and fitted according to the complex shape of the protected target to achieve full coverage of irregular curved surfaces such as vehicles and equipment, fundamentally solving the problems of coverage blind spots and poor fit of traditional rigid protection.

[0022] Multiple spiked components 2 are arranged in an array on the flexible substrate 1. Each spiked component 2 has a spike body 22 protruding from the flexible substrate 1. The spike bodies 22 are vertically fixed to the flexible substrate 1 in an array, forming a dense physical interception layer. When a drone attempts to approach or dive to collide with it, the sharp spikes can make contact with the drone before the target body, effectively forcing it to detonate prematurely or damaging its rotor, thereby intercepting the blast wave at a safe distance.

[0023] Multiple attachments 5, located at the edge of the flexible base 1 or on the side of the flexible base 1 facing away from the spike 22, are used to fix the flexible drape to the protected target and keep the flexible base 1 in a tensioned state, thereby keeping the spike 22 upright. The attachments 5 distributed along the edge of the flexible base 1 not only quickly fix the flexible drape to the target, but more importantly, they change the flexible base 1 from a relaxed state to a high-tension state by tightening the attachments 5. This process transforms the flexible drape from soft to rigid, ensuring that the flexible base 1 has sufficient in-plane stiffness after tensioning, thus providing a stable foundation for the upright spike 22 and preventing it from collapsing when the vehicle is moving or disturbed.

[0024] A stabilizing device is also included, connected between each of the spikes 22 and the flexible substrate 1, to limit the spikes 22 from deviating from their vertical position. This stabilizing device, connecting each spike 22 to the flexible substrate 1, forms a spatial linkage structure. When some spikes 22 are subjected to lateral forces, this device can disperse and transmit the force through its coordinated deformation, thereby limiting large-scale collective tilting of all spikes 22 and greatly enhancing the structural integrity and anti-interference capability of the entire protective array in dynamic environments.

[0025] In summary, the anti-drone flexible camouflage of this invention provides an anti-drone solution that combines all-around protection, rapid deployment, good adaptability, and high dynamic reliability. It successfully transforms a lightweight and flexible camouflage form into a robust and stable three-dimensional interception system, effectively countering the threat of low-cost drones and significantly improving the survivability of high-value targets. (Connecting components) In one embodiment, the stabilizing device includes: The stabilizing net 6 connects all the spikes 22, linking them together to form a unified whole. The stabilizing net 6 physically connects the originally independently erected spikes 22 at the top, forming a holistic mesh structure. When subjected to lateral impacts such as drone collisions, scrapes, or strong winds, the impact force can be rapidly transmitted and dispersed through this network to the surrounding spikes 22 and the connecting components to the flexible substrate 1. This avoids stress concentration at a single point, preventing individual spikes 22 from bending and failing due to overload, significantly improving the structural redundancy and resistance to continuous impacts of the entire protective array.

[0026] The system also includes a connecting component that connects the stabilizing net 6 to the flexible substrate 1. This connecting component links the stabilizing net 6 to the lower flexible substrate 1. When the flexible substrate 1 is tensioned and fixed by the surrounding attachments 5, the connecting component is straightened, thereby pulling the stabilizing net 6 outwards and downwards. This process not only tensions the stabilizing net 6 to its optimal working state, but more importantly, it applies a restoring torque to each spike 22, pointing towards the substrate anchor point. This effectively suppresses and corrects the swaying and tilting of the spikes 22 caused by external forces or substrate movement, ensuring the persistent uprightness and stability of the spike array under dynamic conditions.

[0027] Preferably, the stabilizing net 6 is made of elastic fiber material, which can produce large deformations.

[0028] In this embodiment, the stabilizing net 6 and the connecting components together constitute a stabilizing system. This system not only passively resists deformation but also actively maintains and restores the structural shape. It transforms the numerous spikes 22 on the flexible drape from a potentially loose collection into an organic whole with inherent mechanical connections, capable of coordinated deformation and shared stress. This design fundamentally solves the problem of structural instability in large-area flexible protective structures during dynamic use, significantly improving the protective reliability, environmental adaptability, and service life of the drape.

[0029] In one preferred embodiment, the connecting component is a flexible connector 7, with its two ends fixedly connected to the stabilizing net 6 and the flexible base 1, respectively. The flexible connector 7 (such as a rope or webbing) possesses good tensile strength and a certain degree of deformation capability. When the surface of the protected target is uneven, or when complex relative displacement occurs between the flexible base 1 and the stabilizing net 6 due to impact, the flexible connector 7 can buffer and adapt to this change through its own bending and stretching, avoiding stress concentration or structural interference that may occur with rigid connections, and ensuring the effective operation of the stabilizing device on complex curved surfaces and the reliability of the overall structure.

[0030] During installation, the flexible base 1 is tensioned by the tensioning attachment 5, and the flexible connector 7 is also straightened and pre-tensioned. This pre-tensioning force is evenly transmitted to the stabilizing net 6 through its flexibility, keeping it taut. When the system is subjected to instantaneous impact or vibration, the flexible connector 7 can absorb some energy through slight elastic deformation, and after the impact, it relies on its restoring force to help the system quickly return to a stable taut state, thereby maintaining the dynamic stability of the upright posture of the spike 22.

[0031] In one embodiment, the projected area of ​​the flexible substrate 1 on the horizontal plane is larger than the projected area of ​​the stabilizing net 6; the two ends of the flexible connector 7 are respectively connected to the outer edge of the stabilizing net 6 and the corresponding position of the flexible substrate 1, so that when the flexible substrate 1 is tensioned by the attachment 5, the flexible connector 7 pulls the outer edge of the stabilizing net 6 outward, thereby tightening the stabilizing net 6.

[0032] In this embodiment, because the area of ​​the flexible substrate 1 is larger than that of the stabilizing net 6, there is a "redundant area" on the flexible substrate 1 located outside the stabilizing net 6. The flexible connector 7 is precisely connected to the outer edge of the stabilizing net 6 and a point further out on the flexible substrate 1, forming a series of radial cables pointing from the edge of the stabilizing net to the fixed point of the substrate. When the system attachment 5 tensions and lays the entire flexible substrate 1 in all directions, the substrate material is stretched, and these radial cables are straightened. At this time, the extensive in-plane tension borne by the flexible substrate 1 is concentrated and converted into a strong outward pulling force acting on the outer edge of the stabilizing net 6 through the flexible connector 7, thereby efficiently tightening the stabilizing net 6, which might otherwise sag.

[0033] Its tension comes directly from the tension of the flexible substrate 1 itself, and the two are synchronized without additional operation. Regardless of whether the surface of the protected target is flat or has a complex curvature, as long as the flexible substrate 1 is tightened and attached by the attachment 5, the stabilizing net 6 can automatically obtain a matching and uniformly distributed radial tension, ensuring that it is always in the best working state and providing a stable and reliable top constraint plane for the core protection array (spike body 22).

[0034] This embodiment solves the problem of effectively tensioning the stabilizing net 6 in a large-area flexible system with an extremely simple and ingenious physical configuration. It avoids the need for a separate, complex tensioning mechanism for the stabilizing net 6, simplifying the structure, reducing cost and weight, while ensuring direct and efficient tension transmission. The tensioned stabilizing net 6, as a rigidly enhanced plane, can more effectively link all the spikes 22, suppressing their lateral sway, thereby improving the overall structural stability of the flexible drape and ensuring robust protective performance under various complex working conditions.

[0035] In one embodiment, the stabilizing net 6 is configured such that the connection point between it and each of the spikes 22 is height-adjustable or preset, so that the stabilizing net 6 can be selectively tightened at different height positions according to the curvature of the surface of the protected target, thereby maintaining the vertical stability of the spikes 22.

[0036] In this embodiment, by adjusting or pre-setting the height of the connection points, the effective working plane of the stabilizing net 6 can be raised from the surface closely attached to the flexible substrate 1 to the upper middle part of the spike 22, forming a high-level stabilizing structure that can be suspended above the flexible substrate 1. For flat or low-curvature surfaces, the stabilizing net 6 can be set at a lower position to provide direct lateral constraint; for high-curvature or convex surfaces, the stabilizing net 6 can be raised to a higher position to avoid interference or relaxation between it and the substrate due to the steep curvature of the surface, thereby constructing an effective spatial stabilizing network for target surfaces with different geometric shapes. This allows the same set of drapes to perfectly adapt to various complex shapes, from flat top covers to curved sides.

[0037] In other embodiments, besides the aforementioned stabilization device embodiment centered on "stabilizing net 6 + flexible connecting rope," the stabilization device can also be composed of multiple lateral telescopic links and multiple universal joints. Each lateral telescopic link is connected to the upper middle part of two adjacent spikes 22 through universal joints at both ends, thereby connecting spikes 22 in the same row or column in series. All lateral telescopic links can have a certain degree of mobility in both horizontal and vertical directions. Alternatively, it can be composed of multiple independent flexible cables. A spike 22 is connected by multiple circumferentially arranged flexible cables, with one end of each flexible cable fixedly connected to a specific point on the flexible base 1, and the other end fixedly connected to the upper middle part of the corresponding spike 22.

[0038] In one embodiment, the spike assembly 2 is detachably mounted on the flexible substrate 1.

[0039] In this embodiment, the spike assembly 2 is designed as a detachable, independent module, making the flexible armor no longer a fixed, unchanging whole. When some spikes 22 are damaged, bent, or fail during combat, there is no need to replace or repair the entire armor; simply remove the damaged individual spikes 22 from the flexible base 1 and replace them with intact new components. This greatly simplifies the rapid repair process, significantly reduces maintenance costs and time, and ensures the equipment's continuous operational capability.

[0040] Furthermore, the detachable structure allows the flexible substrate 1 and numerous spike components 2 to be packaged, transported, and stored separately. The flat, flexible substrate 1 is small in volume and lightweight, while the spike components 2 can be tightly packed in containers. The combination of the two significantly reduces the storage and transportation space and weight of the entire system, making it easy to carry and transport by vehicle. In addition, users can flexibly determine the density (full coverage, spaced installation) or type (such as selecting spikes of different lengths 22) of the spikes installed on-site according to the mission threat level and protection requirements, achieving configurable protection levels.

[0041] In addition, the detachable structure solves the pain points of traditional welded protective nets, which are prone to damage and difficult to maintain once damaged. By giving the spiked components 2 a replaceable attribute, not only is the service life of the flexible base 1, which serves as the carrier and main body, extended, but the garrison can also flexibly respond to different threats and mission profiles. It transforms from one-time or semi-permanent protection into a highly adaptable tactical equipment that is reusable, upgradable on-site, and easy to maintain, greatly enhancing its practical value and economic benefits.

[0042] In one preferred embodiment, the anti-drone flexible camouflage integrates detachable spike components 2 with a connecting component for the stabilizing net 6. In this case, the stabilizing net 6 is pre-programmed during production to precisely determine the array layout and spacing of all connection points (i.e., the installation positions of the spikes 22) according to protection requirements. During camouflage installation, operators do not need to measure and locate each spike component 2's installation point on the flexible substrate 1 individually; instead, they can directly use the stabilizing net 6 as a positioning guide template. By sequentially aligning and installing each detachable spike component 2 to its corresponding installation position on the flexible substrate 1 below the pre-determined connection point of the stabilizing net 6, the entire complex spike array can be laid out accurately and in one go. This simplifies the originally cumbersome point-to-point installation process into an efficient modular alignment process, greatly reducing the difficulty, time, and skill requirements of on-site installation.

[0043] In one embodiment, the spike assembly 2 is mounted on the flexible substrate 1 by a threaded fastening structure; the threaded fastening structure includes a mounting hole 11 on the flexible substrate 1, a mating part 21 with internal threads on the spike assembly 2, and a fastener 3 that can pass through the mounting hole 11 and be threadedly connected to the mating part 21.

[0044] In this embodiment, the threaded connection is a mature mechanical connection method that has been proven through long-term engineering. The axial preload generated by tightening the fastener 3 securely locks the spike assembly 2 onto the flexible substrate 1, ensuring that it does not loosen, detach, or rotate under extreme dynamic loads such as high-speed vehicle movement, severe bumps, and explosive impacts, resulting in high connection reliability. Simultaneously, the standard threaded pair makes disassembly and reinstallation operations completely reversible and repeatable, without damaging the flexible substrate 1 or the spike assembly 2 itself, perfectly supporting the system's modular maintenance and reuse requirements.

[0045] Preferably, the fastener 3 is a flat-headed external threaded rod that can mate with the mating part 21 and clamp the flexible base 1 between the two, thereby flexibly connecting the three.

[0046] In one embodiment, the spike 22 is a hollow thin-walled tube.

[0047] In this embodiment, by removing the core material, significant weight reduction is achieved while ensuring sufficient bending strength and puncture resistance, directly reducing the weight of the entire protective suit. This not only makes carrying and installation more convenient and labor-saving, but also minimizes the impact on vehicle fuel economy, maneuverability, and passability, while reducing material costs and processing complexity. It is a key design for achieving a balance between efficient protection and excellent practical performance.

[0048] Preferably, the spike 22 is made of a hollow thin-walled metal tube, but an engineering plastic tube may also be used.

[0049] In one embodiment, the tip of the spike 22 is provided with a rounded protective cap 23. Alternatively, the tip of the spike 22 is provided with a forked strip.

[0050] In embodiments where the protective cap 23 is provided, the smooth protective cap 23 effectively eliminates the risk of accidental punctures or scratches caused by the sharp tip during transport, installation, maintenance, and routine personnel approach, greatly improving the ergonomics and safety of the equipment. Simultaneously, the streamlined cap body reduces wind resistance and prevents debris such as ropes and branches from getting caught and tangled on the spiked tip, ensuring a clean appearance and uninterrupted functionality, and enhancing its long-term applicability in complex environments.

[0051] In embodiments with bifurcated bars, the bifurcated bars physically reduce the effective gap between the spikes 22, forming a denser top interception layer. This significantly increases the probability that the UAV (especially its rotors, supports, or fuselage) will come into contact with, collide with, and be jammed by the spikes. The bifurcated bars can produce more complex tearing and entanglement effects upon impact, thereby more reliably damaging the UAV structure or causing it to detonate prematurely.

[0052] In one embodiment, the outer edge of the flexible substrate 1 is provided with splicing members 4 for splicing multiple flexible drapes together to expand the coverage area.

[0053] In this embodiment, multiple standard-sized flexible drapes can be spliced ​​together using the edge splicing piece 4. Figure 1 This allows for rapid connection and seamless assembly into a complete protective surface sufficient to cover large targets and even ultra-large targets such as temporary shelters. This fundamentally solves the inherent shortcomings of traditional monolithic protective devices, which have fixed dimensions and cannot flexibly adapt to targets of different sizes. It also means that logistics only needs to store and transport a few standard specifications of protective modules, which can be combined to meet the protection needs of almost all equipment, significantly simplifying the supply chain and reducing overall manufacturing and maintenance costs.

[0054] In one embodiment, the splicing component 4 includes a first connecting portion disposed on one side edge of the flexible substrate 1, and a second connecting portion disposed on the other side edge that cooperates with the first connecting portion.

[0055] In this embodiment, by providing a first connecting part (such as the hook side of a Velcro or the male snap) on the first side edge, and providing a second connecting part (such as the fleece side of a Velcro or the female snap) on the corresponding edge on the other side, which precisely matches the first connecting part, any two adjacent edges of the draped garment can be stitched together. Figure 1 This design allows for quick alignment, fitting, and locking. It ensures a strong, smooth seam after splicing, preventing cracking under bumps or wind loads, while avoiding noticeable protrusions or gaps caused by splicing, thus maintaining the continuity and integrity of the protective layer. The first and second connecting parts can be made using Velcro, snaps, quick-release buckles, hook-and-loop fasteners, etc.

[0056] In one embodiment, the flexible substrate 1 is made of a flexible fabric such as high-strength Oxford cloth, PVC plastic film, or thin rubber, and has waterproof and flame-retardant properties. A metal mesh interlayer can be incorporated within it to enhance its strength. In one embodiment, the tethering attachment 5 is made of nylon rope, or it can be a chain. The tethering attachment 5 can also be equipped with an openable hook or a hanging ring.

[0057] The above description is merely an embodiment and does not constitute any limitation on the present invention. Any person skilled in the art can make many possible variations, modifications, or alterations to the technical solutions of the present invention without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention, without departing from the scope of the present invention, should fall within the protection scope of the present invention.
