Description

Technical Field

[0001] This invention relates to the field of compound bow technology, and in particular to a high-energy compound bow that integrates thermal imaging aiming and a multi-wheel unloading system. Background Technology

[0002] In contemporary military and police special operations and counter-terrorism missions, crossbows have long been considered the preferred cold weapon for covert enemy approaches and reconnaissance operations in high-risk environments due to their physical characteristics of producing no gunpowder explosions, smoke, or flames, and having extremely low infrared signatures. However, the mainstream special operations crossbows currently deployed by the military and law enforcement agencies are mostly still at the stage of improving traditional hunting equipment in terms of design concepts, or directly adopt the mechanical structure of civilian competition recurve bows and basic compound bows. When facing complex scenarios such as modern urban warfare, close-quarters combat indoors, and high-intensity hostage rescue, the mechanical structure, ergonomics, and ballistic performance of such equipment have become outdated, making it difficult to meet the stringent requirements of special forces for lightweight equipment, high lethality, and all-weather combat capabilities, and their limitations in practical application are becoming increasingly apparent.

[0003] Currently, existing composite bows still have the following drawbacks: First, the cross-sectional area of ​​the bow arms is too large, which restricts the carrying and deployment of the weapon in narrow spaces such as urban warfare and tunnels; Second, the pulley system's energy-saving ratio is insufficient, requiring the archer to maintain extremely high static tension, which not only consumes a lot of physical strength during continuous combat, but also occupies valuable tactical resources due to the dedicated archer configuration, which is not conducive to the implementation of subsequent tactical formations; Third, the arrow's kinetic energy reserve is insufficient, limiting the effective range and restricting the three-dimensional deployment of counter-terrorism tactics; Fourth, the arrow's aerodynamic performance is poor, and the high flight drag causes the initial velocity to decrease too quickly, resulting in a significant trajectory drop; Fifth, the arrowhead's penetration power is weak, making it difficult to penetrate modern body armor and helmets and other individual protective equipment, and failing to ensure immediate stopping power against high-value targets. Summary of the Invention

[0004] This invention provides a high-energy composite bow that integrates thermal imaging aiming and a multi-round unloading system, in order to solve the technical problems of existing composite bows, such as bulky structure, insufficient unloading leading to difficulty in carrying in narrow spaces and excessive occupation of tactical forces, as well as short arrow range, rapid initial velocity decay and insufficient armor-piercing capability, which make it difficult to deal with modern protected targets.

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this 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 this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0020] As mentioned earlier, the cross-sectional area of ​​the bow arms of existing composite bows is too large, which restricts the carrying and deployment of the weapon in narrow spaces such as bushes, urban warfare, and tunnels; the pulley system has insufficient power-saving design, requiring the archer to be equipped with extremely high static pulling force, which not only consumes a lot of physical strength in continuous combat, but also occupies valuable tactical manpower for dedicated archers, which is not conducive to the implementation of subsequent tactical formations; the arrow's kinetic energy reserve is insufficient, and the effective range is limited, which restricts the three-dimensional deployment of special operations and counter-terrorism tactics; the aerodynamic performance of the arrow body is poor, and the high flight drag causes the initial velocity to decrease too quickly; the arrowhead has weak penetration power and is difficult to penetrate modern body armor and helmets and other individual protective equipment.

[0021] To address this issue, this invention provides a high-energy composite bow integrating thermal imaging aiming and a multi-wheel unloading system. Through the lightweight design of the integrated multi-wheel unloading system and high-rigidity carbon fiber bow frame, it solves the problems of limited portability in confined spaces and excessive physical exertion for shooters associated with traditional composite bows, enabling flexible deployment and effortless operation in special operations. Utilizing a slightly flattened elliptical shaft that is thicker at the front and thinner at the rear, combined with a V-shaped inclined groove front-mounted force-generating structure, it enhances the bending stiffness of the arrowhead, effectively suppressing swaying and initial velocity decay during flight, achieving a straight and stable trajectory and high-speed projection, significantly improving penetration power, capable of penetrating modern individual soldier protective equipment, and achieving the tactical objective of immediately stopping high-value targets. Combined with a silencer bowstring and Bloodline nano-bowstring, it significantly reduces firing noise and vibration. Combined with a passive thermal imaging sight, it ultimately achieves all-weather, all-terrain covert approach and precise sniping, fully meeting the high standards required for equipment in modern counter-terrorism and emergency response missions.

[0022] The following is combined Figures 1-14 The present invention will be described in detail below.

[0023] like Figures 1-7 As shown, this invention provides a high-energy composite bow integrating thermal imaging aiming and a multi-wheel unloading system, including a bow plate integrated assembly 1 arranged opposite to each other.

The bow frame integrated assembly 2 includes a left bow frame 21 and a right bow frame 22, which are composed of two lightweight, forward-bending I-shaped carbon fiber plates with high hardness, high rigidity, and high tensile toughness. An unloading component 3 connected to the bow plate integrated assembly 1 is installed between one end of the left bow frame 21 and the right bow frame 22.

They are fixedly stacked together from the inside to the outside according to their short, medium, and long lengths to generate corresponding elasticity. The six bow plates on both sides can generate a total of 130 kg (approximately 292 lbs) of elasticity, making it an ultra-strong bow.

[0028] like Figure 2As shown, the bow shaft integrated assembly 4 includes a bow shaft handle 41, a first return spring 42, a pull rod 43, a first hook 44, a second return spring 45, a trigger 46, and a hook post 47.

Spring 45, the other end of the second return spring 45 is fixedly connected to trigger 46. Trigger 46 extends from inside the bow handle 41 to the lower part of the bow handle 41. The upper side of trigger 46 is rotatably connected to the inner wall of the bow handle 41 through the first pin post. The other side of the upper part of trigger 46 is provided with a second pin shaft connected to the inner wall of the bow handle 41.

[0029] like Figures 1-2As shown, the unloading wheel integrated assembly 5 includes a small unloading wheel 51 on the right side of the bow rod, a small unloading wheel 52 on the right side of the bow plate, a small unloading wheel 53 on the right side of the bow rod, a large unloading wheel 54 on the right side, a small unloading wheel 55 on the left side of the bow rod, a small unloading wheel 56 on the left side of the bow plate, a small unloading wheel 57 on the left side of the bow rod, a large unloading wheel 58 on the left side, and a ball bearing 59. The small unloading wheel 51 on the right side of the bow rod is rotatably connected to the front of the right side wall of the bow rod handle 41. The small unloading wheel 52 on the right side of the inner bow plate 11 is rotatably connected to the inside of the right side.

The small unloading wheel 55 on the left side of the bow rod is rotatably connected to the front of the left side wall of the bow rod handle 41. The small unloading wheel 55 on the left side of the inner bow plate 14 is rotatably connected to the inside of the left side. The left bow plate is rotatably connected to a small unloading wheel 56. The left side of the bow handle 41 is rotatably connected to a second small unloading wheel 57 on the left side of the bow. The left outer bow plate 16 is rotatably connected to a large unloading wheel 58 on the left side. The right bow plate small unloading wheel 51, the right bow plate small unloading wheel 52, the right bow plate small unloading wheel 53, the right large unloading wheel 54, the left bow plate small unloading wheel 55, the left bow plate small unloading wheel 56, the left bow plate small unloading wheel 57, and the left large unloading wheel 58 are all equipped with carbon fiber bearings 59 with ball bearings. They are covered with lightweight engineering plastic wheels with U-shaped grooves. The grooves are coated with rubber. The eight sets of unloading wheels are designed to withstand a total unloading force of 130 kg (about 292 lbs), which can unload 90% of the elastic force generated by the bow plate.

[0030] like Figures 6-7As shown in the figure, the arrowhead of the arrow body 6 is a triangular sharp arrowhead made of a U-fiber / zirconium-based amorphous alloy composite material with high hardness, high density, good toughness and self-sharpening ability through 3D printing technology. It is the super alloy composite material with the highest hardness, the largest density, good toughness and self-sharpening ability among the currently known alloy materials, and is the most suitable for making armor-piercing arrowheads. This design is conducive to concentrating stress and has excellent directional penetration and structural strength. Micro-particles or rubber components are added to the arrow shaft coating to slightly dissipate vibration energy. Multiple gas diversion grooves are provided on the arrow shaft, which can greatly reduce air resistance and turbulence phenomena, guide the smooth transfer of stress, reduce the risk of standing wave superposition, and facilitate the high-speed forward movement of the arrow body 6. In order to improve the stability of the super-high-speed linear movement of the arrow body 6 after being shot, three tail fins are provided at the tail of the arrow shaft. After the arrow body 6 is shot, when the arrowhead encounters an obstacle, due to the sudden resistance during high-speed movement, under the dual action of the huge inertia and dynamic acceleration generated by the arrow body 6, the huge kinetic energy is instantly converted into potential energy. Coupled with the super-rigidity of the arrowhead, the impact is not blunted, and the penetration depth is increased by 72% compared with traditional tungsten alloy armor steel, and it has considerable armor-piercing ability. An inclined "V" groove in the direction of the arrowhead is provided at the front one-third of the arrow body 6. The bowstring 8 is stuck at the top of the "V" groove. When the bowstring 8 is released, the huge projection thrust is generated from the front of the arrow shaft rather than from the rear of the arrow shaft. Therefore, the inertia of the arrowhead will not have a lag effect, will not cause the arrow body to bend horizontally, will not generate periodic swings around its center of gravity, and will not have an "S"-shaped wave-like flight trajectory.

[0031] As Figures 6-7 shown, the arrow shaft of the arrow body 6 is designed as a flattened elliptical shape that is thick at the front and thin at the rear, and is made of a carbon-aluminum alloy hybrid structure material, which combines the high damping of carbon fiber and the stability of aluminum alloy, effectively absorbs high-frequency vibration energy, and can reduce air resistance and the ultra-high initial velocity decay after the arrow body 6 is shot. The three tail fins of the arrow body 6 are arranged in an inverted "pin" shape with 1 at the bottom and 2 at the top. The bowstring 8 is slightly higher than the upper plane of the upper two tail fins, which not only avoids the cutting of the tail fins on the bowstring 8 after release, but also ensures the smooth and stable state of the rod body during forward movement. According to the public test data, for every 增加10 pounds increase in the pulling force of the compound bow bow plate, the arrow speed increases by about 20 - 25 feet per second (fps). Based on the initial speed of about 340 fps (104 m / s) of a 70-pound compound bow, the initial speed of a 292-pound compound bow can reach or exceed 240 m / s. According to the kinetic energy formula E = ½MV 2 calculation, the kinetic energy may exceed 8 J. If in high-altitude areas, for every 1000 m increase in altitude, due to the thinner air and smaller resistance, the range can be increased by 8 m, and the higher the altitude, the faster the initial speed and the farther the range, and it can reach or approach the initial kinetic energy level of small-caliber rifle bullets, ensuring the huge armor-piercing ability of the arrow body 6 from the design and materials.

[0032] As Figure 1 It should be noted that there seems to be an error in the kinetic energy calculation part in the original text. The correct calculation result should be that the kinetic energy may exceed 800 J instead of 8 J as translated above. Also, the expression "增加10 pounds" in the original text should be "increase by 10 pounds". The above translation has corrected these errors for a more accurate understanding.As shown, the sound-absorbing bowstring assembly 7 is integrated into a highly elastic, high-impact-resistant synthetic material, Spuu-DA elastomer (supramolecular polymer), which can minimize or eliminate the vibration sound of the bowstring 8 during bow and arrow use, maximizing the "silence" of the arrow's launch and maximizing the archer's concealment and the element of surprise in scouting and counter-terrorism operations. The bowstring 8 uses a Bloodline composite material (ultra-high-strength synthetic fiber) nano-coating, which features zero creep and low elongation, maintenance-free operation, wear resistance and stain resistance, physical stability in extreme environments, and triple protection against water, sand, and corrosion under complex conditions, meeting the maximum tensile strength requirements of this composite bow design.

[0033] like Figures 1-14 As shown, the night vision thermal imaging sight 9 is mounted on the upper part of the bow handle 41 via a mount. The night vision thermal imaging sight 9 first uses a power supply protection circuit to suppress and protect against abnormal fluctuations and noise in the power input, transient overvoltage, and surge current, improving the electromagnetic compatibility of the circuit. After the charging rectifier circuit intelligently charges the battery, it detects the infrared radiation emitted by objects to achieve imaging. Employing passive thermal imaging technology, it does not emit infrared rays itself, but instead uses a thermal element to detect the temperature difference or radiation difference between the target and the background, directly capturing the target's own infrared radiation. The signal processing unit performs uniformity correction and image processing (noise reduction and contrast enhancement) on the electrical signal, improving and optimizing signal quality. Through an OLED display or other display device, the processed signal is presented as images of different colors, with color intensity reflecting the intensity of infrared radiation. Combined with an AI perception system, the device can intelligently identify human and animal targets. Through infrared radiation reception, photoelectric conversion, image enhancement, and image display, the weak light signal at night is converted into an electrical signal, and image display technology provides a clear and visible image, enabling accurate shooting even in adverse weather conditions such as darkness, rain, snow, fog, and sandstorms.

[0034] In actual use, the user holds the device by the handle and then pulls the lever 43 backward. The first return spring 42 extends accordingly, and the bowstring 8 attached to the first hook 44 is hooked. By continuously pulling the lever 43 backward, the bowstring 8 wound on the unloading wheel integrated assembly 5 is pulled, and the unloading wheel integrated assembly 5 also rotates until the bowstring 8 is pulled onto the hook column 47. Then, the user pushes the lever 43 forward, and the lever 43 will return to its original position under the traction of the first return spring 42.

[0035] Then, push the arrow 6 into the slot on the bow handle 41. The top of the V-shaped groove on the arrow 6 is locked onto the fully drawn bowstring 8. According to the passive display of the night vision thermal imaging sight 9, aim at the relevant part of the imager. After pulling the trigger 46, the trigger 46 rotates along the first pin shaft. At the same time, the pin hole on the upper part of the trigger 46 allows the hook post 47 to slide down along the second pin shaft, so the bowstring 8 on the hook post 47 is released. At this time, the arrow 6 is launched at high speed. Then release the trigger 46. One of the functions of the second return spring 45 is similar to the safety pin of the gun trigger. The trigger 46 and the hook post 47 are reset under the traction of the second return spring 45.

[0036] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.
