Description

Technology Field

[0001] The present invention relates to a personal protective shield, and more specifically, to a personal protective shield capable of protecting a user by providing a protective surface that absorbs and disperses the impact generated upon collision with an approaching drone, and capable of responding to a threatening enemy by emitting electromagnetic waves. Background Technology

[0002] Due to the recent rapid development and widespread adoption of drones (Unmanned Aerial Vehicles, UAVs), drone-based attacks are emerging as a new threat not only in the military but also in the civilian sector.

[0003] Attacks using drones are becoming a significant concern in both military and civilian sectors. Existing defensive equipment, particularly traditional ballistic shields, is primarily designed to defend against projectiles or explosives launched from the ground. However, these conventional shields show limitations in defending against aerial drone attacks that can approach from various angles and heights.

[0004] Currently used personal shields generally provide protection only from the front or sides, leaving users vulnerable to aerial drone attacks. While there have been attempts to develop anti-drone protection equipment, most solutions focus on drone detection systems rather than physical protection.

[0005] Furthermore, in conventional technology, various detection-oriented technologies such as radar, RF detectors, and image-based tracking systems have been developed to counter drone threats; however, most of these technologies are configured as fixed systems or vehicle-mounted units, which has the limitation of not being portable and usable by individuals.

[0006] Furthermore, while bulletproof structures utilizing multi-layered Kevlar or metal materials are applied to existing shield structures, they are limited to merely absorbing or blocking impact, and currently lack multi-stage dispersion structures and active response capabilities against explosions or high-energy impacts. The problem to be solved

[0007] The present invention aims to solve the problems described above by providing a personal protective shield that can be carried by an individual and effectively respond to a collision with an approaching drone.

[0008] In addition, the present invention aims to provide a personal protective shield capable of providing a protective surface in all directions, including the top and sides, to counter drone attacks approaching from above or high positions.

[0009] In addition, the present invention aims to provide a personal protective shield capable of expanding the protective area by arranging expandable shield sections that can be deployed and stored on both sides of the main shield section.

[0010] In addition, the present invention aims to provide a personal protective shield capable of responding to approaching or hidden enemies using a microwave-based countermeasure. means of solving the problem

[0014] The main shield portion may include a base plate comprising aluminum or stainless steel and having a vibration-absorbing groove formed on its back surface, a shield layer comprising glass fiber and flame-retardant resin and laminated on the base plate, a shock-absorbing layer laminated on the shield layer and absorbing applied shock, and a shock-dispersing layer laminated on the shock-absorbing layer and dispersing applied shock.

[0015] The shock-absorbing layer may include a shock-absorbing fabric that comprises Kevlar and is laminated in multiple layers, and a fixing fabric that includes wool that is disposed between the shock-absorbing fabrics and fixed to the shock-absorbing fabrics by adhesion.

[0017] The impact dispersion layer may comprise a plurality of ball placement plates formed by combining a hexagonal top plate in which a first unit ball placement hole is formed and a hexagonal bottom plate in which a second unit ball placement hole is formed that is combined with the first unit ball placement hole to form a ball placement hole, and a plurality of balls rotatably disposed in the first unit and second unit ball placement holes.

[0018] The above ball can come into contact with the shock absorption layer.

[0019] The above electromagnetic wave emitting unit may include an electromagnetic wave generator that generates microwaves, a plurality of antennas disposed on the front of the main shield unit and emitting the electromagnetic waves generated by the electromagnetic wave generator, and an emission guide configured to be adjustable in length and detachable and guiding the emission direction of the electromagnetic waves.

[0020] The plurality of antennas are classified into first to n antenna groups, and each of the antenna groups can emit microwaves of different frequencies. Effects of the invention

[0027] In order to explain the present invention, the operational advantages of the present invention, and the objectives achieved by embodiments of the present invention, preferred embodiments of the present invention are illustrated below and examined with reference thereto.

[0028] First, the terms used in this application are used merely to describe specific embodiments and are not intended to limit the invention; singular expressions may include plural expressions unless the context clearly indicates otherwise. Furthermore, in this application, terms such as "comprising" or "having" are intended to specify the existence of the features, numbers, steps, actions, components, parts, or combinations thereof described in the specification, and should be understood as not precluding the existence or addition of one or more other features, numbers, steps, actions, components, parts, or combinations thereof.

[0029] In describing the present invention, if it is determined that a detailed description of related known components or functions may obscure the essence of the invention, such detailed description is omitted.

[0030] FIG. 1 is a drawing showing an example configuration of the front shape of a personal protective shield according to the present invention, and FIG. 2 is a drawing showing an example of the rear shape of a personal protective shield according to an embodiment of the present invention. FIG. 1 and FIG. 2 show an expanded shield portion, which will be described later, in an unfolded state.

[0031] Referring to FIGS. 1 and FIGS. 2, the personal protective shield (10) according to the present invention may include a main shield portion (100), an extension shield portion (200), and an electromagnetic wave emitting portion (150).

[0032] The main shield (100) can be configured to be portable for a user who requires protection against drones and threatening enemies. A handling arm (102) that the user holds can be provided for carrying the main shield (100). The handling arm (102) has a predetermined length, and it is preferable that the middle portion be bent to create a gap with the back surface of the main shield (100) so that the user's arm can easily enter. At this time, the handling arm (102) can be positioned at a predetermined angle toward both ends of the main shield (100).

[0033] The handling arm (102) may be made of a specific elastic material. In this case, both ends of the handling arm (102) may be rotatably connected to the joint (214C) of the two-section link (214) described later. The end of the handling arm (102) may also be rotatably connected to the end of the handle bar (216).

[0034] Accordingly, when the expansion shield portion (200) described below is deployed and stored on the back of the main shield portion (100), a pair of handling arms (102) can operate in conjunction with this.

[0035] The main shield portion (100) may be in the shape of a plate having a predetermined size and area.

[0036] The main shield portion (100) may be in the form of a pentagonal plate with a width and height of 450 mm and 650 mm, respectively. Here, the size of the main shield portion (100) may be changed according to the user's needs. In addition, although the main shield portion (100) in the present invention is in the shape of a pentagon, it may be formed in a predetermined polygonal shape, such as a rectangle, according to the user's needs.

[0037] The main shield (100) can also be used in a form that the user carries on their shoulder, and in this case, it can provide a protective surface from the user's head to the pelvis.

[0038] Here, a fixing pin (104) can be disposed on the lower rear side of the main shield portion (100) so as to be withdrawn by user operation and to support the personal protective shield (10) according to the present invention while in contact with the ground.

[0039] The fixing pin (104) can be formed in the shape of a rod having a predetermined length.

[0040] The fixing pin (104) can be detached from the main shield (100) when necessary and used as a defensive weapon.

[0041] It is preferable that the main shield part (100) has a weight of 5 kg or less. In addition, it can be durable against high temperatures of 200°C (within 2 seconds) or higher.

[0042] The expansion shield section (200) is positioned on each side of the main shield section (100), and can be deployed outward from the main shield section (100) when necessary to expand the protective surface, and can be stored back in its original position after use.

[0043] The expansion shield portion (200) may be formed in the shape of a rectangular plate having a predetermined size.

[0044] When the extended shield section (200) is deployed, it can provide a protective surface with a size of 900mm x 650mm together with the main shield section (100). The area of ​​the provided protective surface can be changed according to the user's needs.

[0045] FIGS. 3 and FIGS. 4 are drawings showing different embodiments of the planar form of the personal protective shield shown in FIGS. 1 and FIGS. 2.

[0046] Referring to FIG. 3, the main shield section (100) and the extension shield section (200) are shown to be arranged in a straight line.

[0047] Referring to FIG. 4, it can be seen that the center of the main shield portion (100) is bent into a V shape, so that the main shield portion (100) and the extended shield portion (200) form a V shape.

[0048] In addition to the details shown in the drawing, the main shield part (100) can be formed in various forms, such as having a predetermined curved shape.

[0049] Let us examine the more detailed configuration of the main shield section (100) and the expansion shield section (200).

[0050] The main shield section (100) and the extended shield section (200) may be formed by laminating a metal layer comprising one or more of titanium (Ti), tungsten (w), aluminum (Al) and stainless steel (STS), and a non-metal layer comprising one or more of heat-resistant paraamide-based materials, carbon wire film, PC, PVC, and resin.

[0051] In addition, it is preferable that an electromagnetic wave absorption layer be formed on the surface of the main shield part (100) and the extended shield part (200) by applying an electromagnetic wave absorption paint.

[0052] FIG. 5 is a drawing for explaining the storage of the expansion shield part used in the present invention.

[0053] For the deployment and storage of the expansion shield part (200), the following deployment guide (210) may be provided.

[0054] The deployment guide (210) may include an LM guide (212), a two-section link (214), and a handlebar (216).

[0055] The LM guide (212) can be horizontally positioned on each side of the upper rear surface of the main shield section (100). Additionally, the upper end of the expansion shield section (200) is connected to the LM guide (212) to provide a movement path for the deployment and storage of the expansion shield section (200).

[0056] The link (214) can operate to deploy and store the expansion shield (200).

[0057] FIG. 6 is a diagram showing the connection relationship between the two-section link used in the present invention and other components.

[0058] The two-section link (214) rotatably connects the first bollard arm (214A) and the second bollard arm (214B) by a joint (214C). It is preferable that the first bollard arm (214A) and the second bollard arm (214B) be of the same shape and size.

[0059] FIG. 7 is a drawing showing an example of the configuration of the first bollard arm used in the present invention. Since the first bollard arm (214A) and the second bollard arm (214B) are configured identically, we will examine only the configuration of the first bollard arm (214A) here.

[0060] The first bollard arm (214A) has first to third unit rods (2144A, 2144B, 2144C) having a predetermined length and diameter arranged at regular intervals inside a cylinder (2142) having a predetermined length and diameter, and first and second unit springs (2146A, 2146B) may be arranged in the spaced-apart spaces of the first to third unit rods (2144A, 2144B, 2144C). Both ends of the first and second unit springs (2146A, 2146B) may be fixed to the first to third unit rods (2144A, 2144B, 2144C) by welding.

[0061] Here, the first and second unit springs (2146A, 2146B) can apply elastic force to the first to third unit rods (2144A, 2144B, 2144C). Thus, when the first bollard arm (214A) operates, it can absorb the shock when an external shock is applied.

[0062] Here, one end of the first bollard arm (214A) can be rotatably connected to the center of the back of the main shield part (100), and one end of the second bollard arm (214B) can be rotatably connected to the front of the extension shield part (200).

[0063] The two-section link (214) is positioned on each side of the main shield section (100) to connect the main shield section (100) and each of the extension shield sections (200) on both sides of the main shield section (100).

[0064] Here, a pair of vertical links (214) may be arranged on each side of the main shield (100) to facilitate the deployment and storage of the expansion shield (200).

[0065] The handlebar (216) may be formed in the shape of a rod having a predetermined length. Both ends of the handlebar (216) may be rotatably connected to the joint (214C) of the two-section link (214) positioned on both sides of the main shield (100).

[0066] A handle knob (217) that the user grips can be placed in the center of the handlebar (216).

[0067] The handlebar (216) may be placed on each of the upper and lower two-section links (214), but for ease of operation, it may be placed only on the upper or lower two-section link (214).

[0068] Let us refer again to Fig. 5.

[0069] When the expansion shield section (200) is deployed on both sides of the main shield section (100), as shown in FIG. 5, if the handle bar (216) is lifted, the joint (214C) of the two-section link (214) connected to both ends of the handle bar (216) can be lifted. At this time, the two-section link (214) is bent with respect to the joint (214C), and the expansion shield section (200) can be stored on the back of the main shield section (100).

[0070] And, when the user lowers the handlebar (216), the extension shield section (200) can be extended outward from both sides of the main shield section (100).

[0071] At this time, in order to facilitate storage of the expansion shield section (200), a guide block (215) placed in the main shield section (100) may be connected to the end of the two-section link (214) connected to the expansion shield section (200).

[0072] It is horizontally positioned on the main shield portion (100) of the guide block (215) so that stable movement can be achieved when the two-section link (214) connected to the extension shield portion (200) moves.

[0073] Meanwhile, the main shield (100) is preferably equipped with NIJ-4 ballistic protection to counter external attacks (such as impact or explosion of a drone). NIJ-4 (Level IV) ballistic protection is the highest level of protection specified in the 'NIJ Standard 0101.06', the ballistic protection standard of the National Institute of Justice (NIJ).

[0074] FIG. 8 is a cross-sectional view showing an example of the configuration of the main shield part used in the present invention.

[0075] Referring to FIG. 8, it can be seen that the main shield portion (100) includes a base plate (110), a shield layer (120), a shock absorption layer (130), and a shock dispersion layer (140).

[0076] The base plate (110) is positioned at the lowest side of the main shield part (100) and can provide support for the components described below.

[0077] The base plate (110) may be a plate shape made of aluminum or stainless steel. Additionally, a plurality of circular vibration absorption grooves (112) may be formed on the back surface of the base plate (110) to absorb vibration.

[0078] A base plate (110) with a vibration absorption groove (112) formed therein can be formed by a press process.

[0079] It is preferable that the vibration absorption groove (112) be formed along a predetermined spiral from the center of the back surface of the base plate (110) or formed radially from the center of the back surface.

[0080] The shield layer (120) can be laminated on top of the base plate (110).

[0081] FIG. 9 is a cross-sectional view showing an example of the configuration of the shield layer used in the present invention.

[0082] The shield layer (120) is formed with a core layer (124) made of glass fiber and flame-retardant resin, and a PC film (122) applicable to reinforced glass, such as PC or PVC, can be placed on the upper and lower surfaces of the core layer (124), respectively.

[0083] The shield layer (120) can absorb shocks that were not absorbed by the shock absorption layer (130) described later.

[0084] The shield layer (120) can be completed by placing PC films (122) on the upper and lower sides of the center layer (124), and then applying a predetermined pressure on a predetermined vacuum furnace while heating at a temperature of 60 to 220°C for at least one hour.

[0085] The shock absorption layer (130) is positioned on top of the shield layer (120) and can absorb shocks that pass through the shock dispersion layer (140) described later. In particular, a portion of the upper surface of the shock absorption layer (130) contacts the lower end of the ball (144) described later and can absorb shocks transmitted through the ball (144).

[0086] Let's look at an example of the fabrication of the shock absorption layer (130).

[0087] Figure 10 is a diagram showing the composition of a shock-absorbing layer through the lamination of a shock-absorbing fabric and a fixed fabric.

[0088] First, multiple shock-absorbing fabrics (132) made of Kevlar material can be prepared.

[0089] Multiple shock-absorbing fabrics (132) can be fixed by adhesive after being laminated. Here, the adhesive used may be a conventional adhesive used for Kevlar bonding. When multiple shock-absorbing fabrics (132) are laminated, it is preferable to laminate them by arranging them so that their weaving directions intersect perpendicularly to each other.

[0090] At this time, a fixed fabric (134) made of wool may be placed between the multiple shock-absorbing fabrics (132). At this time, the fixed fabric (134) may be woven to have an angle of 22.5 to 45 degrees with respect to the shock-absorbing fabrics (132).

[0091] The fixed fabric (134) can be fixed to the shock-absorbing fabric (132) by adhesion. During the adhesion process, the adhesive may be applied over the entire surface of the fixed fabric (134), but the adhesive may also be applied only to a part of the fixed fabric (134).

[0092] The shock-absorbing fabric (132) and the fixing fabric (134) can be completed by heating them at a temperature of 100°C or higher for at least one hour in a predetermined vacuum furnace to fix them.

[0093] Let's look at another embodiment of the production of the shock absorption layer (130).

[0094] FIG. 11 is a cross-sectional view showing another example of the composition of the shock-absorbing layer used in the present invention.

[0095] It can be seen that the shock absorption layer (130A) includes a fiber fixing layer (132A) and a fiber pile layer (136A).

[0096] The fiber fixing layer (132A) may be formed in a plate shape having a predetermined thickness and area. The fiber fixing layer (132A) may include a sheet made of metal wire or carbon wire.

[0097] The fiber pile layer (136A) can be formed by fixing one end of a fiber having a certain length to one side of the fiber fixing layer (132A).

[0098] Let's examine the formation of the fiber pile layer (136A).

[0099] First, to secure the fiber, an adhesive film (134A) is attached to the surface of the fiber fixing layer (132A). The adhesive film is a film coated with a predetermined adhesive, and it is preferable that it be a double-sided adhesive film for attachment to the fiber fixing layer (132A) and for securing the fiber.

[0100] The user can fix the fibers by embedding them into an adhesive film. Here, the fixation of the fibers can be performed in the same way as the work of embedding fibers during carpet manufacturing.

[0101] The user fixes one end of the fiber to the adhesive film (134A) as if planting it so that the fiber stands upright. It is preferable to place a separate fiber horizontally at the bottom of the upright fiber so that the fiber fixed to the adhesive film (134A) can maintain its upright position.

[0102] After the fixation of the fibers is completed, it is desirable to cut the upper part of the fibers so that the fiber pile layer (136A) has a uniform thickness.

[0103] In the present invention, the fiber used to form the fiber pile layer (136A) is preferably a paraamide fiber.

[0104] The shock dispersion layer (140) is laminated on top of the shock absorption layer and can disperse shocks applied from the outside.

[0105] At this time, the shock dispersion layer (140) may be placed across the upper front surface of the shock absorption layer, but may be partially placed only at locations where the user needs it, such as the center or edge of the shock absorption layer, depending on the user's needs.

[0106] The shock dispersion layer (140) may include a ball placement plate (142) and a ball (144).

[0107] As illustrated in the drawing, the ball placement plate (142) may include an upper plate (142A) and a lower plate (142B) that are overlapped with each other.

[0108] The top plate (142A) and the bottom plate (142B) may be formed in the shape of plates having a predetermined area and shape.

[0109] Referring again to FIG. 8, the configuration of the ball placement plate (142) will be explained.

[0110] The top plate (142A) and the bottom plate (142B) may include any one of titanium (Ti), tungsten, or Inconel.

[0111] The upper plate (142A) and the lower plate (142B) may be formed in the form of plates having the same thickness, area, and shape. Additionally, a plurality of first unit ball placement holes (143A) may be formed in the upper plate (142A), and a plurality of second unit ball placement holes (143B) may be formed in the lower plate (142B). The first unit ball placement holes (143A) and the second unit ball placement holes (143B) may be formed at corresponding positions.

[0112] The first unit ball placement hole (143A) may be formed with different diameters on the front and back sides of the top plate (142A). The diameter of the first unit ball placement hole (143A) on the back side of the top plate (142A) corresponds to the diameter of the ball (144), but the diameter of the first unit ball placement hole (143A) on the front side of the top plate (142A) may be formed smaller than the diameter on the back side. Additionally, the inner surface of the first unit ball placement hole (143A) may be formed with a curvature corresponding to the curvature of the ball (144).

[0113] Additionally, the first unit ball placement hole (143A) and the second unit ball placement hole (143B) can be formed in a symmetrical shape. That is, the diameter of the second unit ball placement hole (143B) on the front side of the bottom plate (142B) corresponds to the diameter of the ball (144), and the diameter of the second unit ball placement hole (143B) on the back side of the bottom plate (142B) corresponds to the diameter of the first unit ball placement hole (143A) on the back side of the top plate (142A).

[0114] When the first unit ball placement hole (143A) and the second unit ball placement hole (143B) are combined, a ball placement hole (143) having a predetermined diameter can be formed.

[0115] A ball (144), described later, can be rotatably placed inside the ball placement hole (143).

[0116] The ball (144) is in the shape of a sphere with a predetermined diameter, and when an external shock is absorbed, it rotates and can disperse the shock in several directions.

[0117] The ball (144) may include bearing steel.

[0118] If the diameter of the ball (144) is greater than the thickness of the ball placement plate (142), it can be set in various ways according to the user's needs.

[0119] A ball (144) can be placed in the ball placement hole (143) formed in the ball placement plate (142).

[0120] The user can complete the ball placement plate (142) as follows.

[0121] After placing the bottom plate (142B), balls (144) are placed in the second unit ball placement holes (143B). After the placement of balls (144) is completed, the top plate (142A) is placed on the top of the bottom plate (142B) and can be fixed to the bottom plate (142B) by bolt fastening or welding.

[0122] At this time, the first unit ball placement hole (143A) and the second unit ball placement hole (143B) can be combined to form a ball placement hole (143).

[0123] At this time, as shown in FIG. 12, the ball placement plate (142) may be made of a honeycomb structure.

[0124] In the honeycomb structure forming the ball placement plate (142), a single ball (144) can be placed in each single honeycomb cell.

[0125] At this time, it is preferable that the spacing between the balls (144) be 1 to 2 times the diameter of the balls (144). That is, if the spacing between the balls (144) is too far, the external impact cannot be dispersed by the balls (144) and the probability of it being applied directly to the ball placement plate (142) increases, so it is preferable that the spacing between the balls (144) not exceed 2 times the diameter of the balls (144).

[0126] The configuration of the main shield section (100) described above can be applied in the same way to the expansion shield section (200).

[0127] FIG. 13 is a cross-sectional view showing an example of the configuration of an electromagnetic wave emitting unit used in the present invention.

[0128] The electromagnetic wave emitting unit (150) can irradiate microwaves (2.2 to 2.6 GhHz) toward an approaching drone or a hidden enemy. Additionally, when irradiating complex electromagnetic waves, it can generate electromagnetic waves in the range of 100 kHz to 3 GHz.

[0129] Drones exposed to microwaves may suffer damage to their control circuits, and hidden enemies may have their threatening behavior restricted due to thermal damage caused by the microwaves.

[0130] The electromagnetic wave emitting unit (150) may include an electromagnetic wave generator (152), an antenna (154), and an emission guide (156).

[0131] The electromagnetic wave generator (152) can generate microwaves by receiving external power. At this time, it is preferable that the output of the microwave be 2 kW or more.

[0132] The electromagnetic wave generator (152) may be placed in the main shield section (100) or installed separately from the main shield section (100), or placed in a location according to the user's needs. Additionally, a power supply means (not shown) may be placed in the main shield section (100), but may be carried by a separate person.

[0133] The antenna (154) can transmit microwaves generated from the electromagnetic wave generator (152).

[0134] The antenna (154) can be arranged in multiple numbers on the front of the main shield (100).

[0135] Figure 1 illustrates an example of the arrangement of the antenna (154) on the front of the main shield (100).

[0136] As shown in the illustration, it can be seen that the plurality of antennas (154) are classified into first to third antenna groups (G1, G2, G3) that form concentric circles.

[0137] The first antenna group (G1) located at the center can emit microwaves of the highest frequency, and as one moves toward the periphery, that is, toward the second and third antenna groups (G2, G3), the frequency of the emitted microwaves can decrease.

[0138] For example, the frequency of the emitted microwave is 2.2 to 2.6 GhHz, so the first antenna group (G1) can emit microwaves with a frequency of 2.6 GhHz, and the second and third antenna groups (G2, G3) can emit microwaves with a frequency of 2.4 GhHz and 2.2 GhHz, respectively.

[0139] At this time, the emitted microwave can have an output of 0.1 kWatt to 30 kWatt. In addition, it can have a higher output if necessary.

[0140] The emission guide (156) can guide the electromagnetic waves emitted from the antenna (154) in one direction, that is, in the direction where a threatening enemy is expected to be located.

[0141] The discharge guide (156) may be formed in a cylindrical shape having a predetermined length and diameter. At this time, it is preferable that the discharge guide (156) be configured to allow for length adjustment in a telescopic manner.

[0142] At this time, it is preferable that the discharge guide (156) be configured to be detachable as needed.

[0143] For example, if the target being responded to is a person, the response can be made with the release guide (156) attached. However, if it is determined that a drone equipped with an explosive warhead is approaching, it is preferable to remove the release guide (156).

[0144] The present invention, as described above, is portable by an individual and can respond to the approach and collision of hostile drones. It can provide a protective surface in all directions, including to the sides and against drone attacks approaching from a higher position than oneself, and can expand the protective area by arranging deployable and retractable expansion shield sections on both sides of the main shield section. Furthermore, the present invention can respond to approaching or hidden enemies using microwave-based countermeasures.

[0145] As such, the present invention has been described with reference to an embodiment illustrated in the drawings, but this is merely illustrative, and those skilled in the art will understand that various modifications and equivalent alternative embodiments are possible therefrom.

[0146] Therefore, the true scope of technical protection of the present invention should be determined by the technical concept of the appended claims. Explanation of the symbols
