Description

Technical Field

[0001] This invention relates to the field of armor-piercing arrow launching device technology, and in particular to a bowless armor-piercing arrow launching device for military and police use with thermal imaging aiming. Background Technology

[0002] In modern military and police special operations and counter-terrorism missions, covert infiltration and silent strikes are crucial means of achieving tactical surprise. Crossbows, due to their sound-absorbing and light-less characteristics, are often used in covert operations such as "sentry raids." However, existing military and police crossbows still follow traditional mechanical designs, which presents significant limitations in practical applications. To address these issues, the industry urgently needs a new type of launching device that integrates advanced observation and aiming technologies and breaks through the traditional power structure of crossbows to meet the operational demands of complex combat environments.

[0003] Existing technologies, including traditional crossbows, suffer from the following shortcomings: First, they rely on a single power source, entirely dependent on the elastic potential energy stored in the deformation of the bowplate to launch the arrow. If the bowplate is damaged, the device fails. Furthermore, the large wingspan of the bowplate limits its portability and operation in confined spaces or complex terrain. Second, limited by material strength and ergonomics, the elasticity design of traditional bowplates is difficult to improve, making it difficult to achieve high-poundage output without auxiliary support. Third, the aerodynamic layout of the arrow is unreasonable, resulting in high flight drag and rapid initial velocity decay, limiting the effective range and insufficient arrowhead penetration, making it difficult to penetrate modern protective equipment. Fourth, the design of the effort-saving wheel system is still imperfect, and the drawing process consumes a lot of energy, making it unsuitable for non-professional archers. Continuous combat can easily lead to archer fatigue, affecting subsequent tactical execution. Fifth, they have poor environmental adaptability. Traditional mechanical sights are limited in use under low visibility or severe weather conditions such as darkness, sandstorms, rain, snow, and heavy fog. Moreover, the device relies on the precise coordination of the bowplate and bowstring to complete firing, resulting in a low system fault tolerance. Summary of the Invention

[0020] 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 some embodiments of this invention, not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort, or equivalent and different substitutions and modifications to the technical solutions, features, and methods described in the embodiments of this invention, including changes to the wire diameter, stiffness, elasticity, quantity, and protective tube of the spring, additions or reductions and position adjustments of the unloading wheel, modifications to the trigger and the launching body, etc., are all within the scope of protection of this invention.

[0021] As mentioned earlier, traditional crossbow technology relies on a single power source, entirely dependent on the elastic potential energy stored in the deformation of the bowplate to launch the arrow. If the bowplate is damaged, the device fails. Furthermore, the large wingspan of the bowplate limits its portability and operation in confined spaces or complex terrain. Due to limitations in material strength and ergonomics, the elasticity design of traditional bowplates is difficult to further improve, making it difficult to achieve high-poundage output without auxiliary support. The aerodynamic layout of the arrow is unreasonable, resulting in high flight drag and rapid initial velocity decay, which limits the effective range and the arrowhead's penetration ability, making it difficult to penetrate modern protective equipment. The energy-saving wheel system design is still imperfect, and the drawing process consumes a lot of energy, which is not conducive to operation by non-professional archers. Continuous combat can easily lead to archer fatigue, affecting subsequent tactical execution. The environmental adaptability is poor. Traditional mechanical sights are limited in use in low visibility or severe weather conditions such as darkness, sandstorms, rain, snow, and heavy fog. Moreover, the device relies on the precise coordination of the bowplate and bowstring to complete firing, resulting in a low system fault tolerance.

[0022] To address this, the present invention provides a military and police-use bowless armor-piercing arrow launching device with thermal imaging aiming. This device utilizes a bracket integrated assembly to support the spring integrated assembly and the protective tube, completely eliminating the dependence on the bowplate found in traditional crossbows. This solves the problems of bowplate damage leading to failure and excessive wingspan, achieving a flattened and miniaturized design. By configuring a drag wheel integrated assembly consisting of ten drag wheels, combined with a multi-stage winding method for the drag string, the pulling force required for compressing the spring is significantly reduced, resolving the conflict between high-power output and ergonomics, enabling high-energy charging with handheld operation. Furthermore, by opening vent holes in the protective tube wall, and... The high-speed movement of the integrated launcher components effectively balances the air pressure inside the tube and weakens the shock wave, solving the problem of high launch noise and achieving the goal of silent firing and improved tactical concealment. By adopting a dedicated rocket body with a launch slot at the front and an optimized aerodynamic layout, combined with the huge kinetic energy released by the parallel connection of two springs, the defects of low initial velocity, rapid decay, and insufficient penetration force of the rocket body are solved, achieving the goal of long-range precision armor penetration with high initial velocity and low drag. By integrating a night vision thermal imaging sight above the protective tube, the dependence on visible light is eliminated, solving the problem of observation and aiming in adverse weather and dark environments, and achieving the goal of precision sniping in all weather and all terrains.

[0023] like Figures 1-18As shown, the present invention provides a military and police-use bowless armor-piercing arrow launching device with thermal imaging aiming, comprising: a support integrated assembly 1, the support 1 being made of lightweight "I"-shaped carbon fiber material, the support integrated assembly 1 including a front support 11, a left support 12 and a right support 13, one end of the front support 11 being fixedly connected to the left support 12, the other end of the front support 11 being fixedly connected to the right support 13, a spring integrated assembly 6 being provided inside the sheath integrated assembly 3, a sheath cutout 7 being provided on the top of the sheath integrated assembly 3, two sets of first grips 10 being provided at the bottom of the sheath integrated assembly 3, and a night vision thermal imaging aiming scope 14 being fixedly provided on the upper rear end of the sheath integrated assembly 3.

[0024] like Figure 1 As shown, a protective tube assembly 3 is fixedly connected to the middle of the front bracket 11. The protective tube assembly 3 includes a right protective tube 31, a square tube 33, a left protective tube 32, and a vent hole 34. The left protective tube 32 and the right protective tube 31 are made of ultra-hard aviation aluminum, and the square tube 33 is made of aluminum alloy. The arrangement of the left protective tube 32 and the right protective tube 31 avoids the possibility of the spring being easily exposed to ultraviolet rays in sunlight and side impacts, which may cause delamination or breakage. The right protective tube 31 and the left protective tube 32 are fixedly arranged opposite each other at the middle edge of the front bracket 11. The other end of the right protective tube 31 and the left protective tube 32 is fixedly arranged with a square tube 33. Several vent holes 34 are provided on the walls of the right protective tube 31 and the left protective tube 32.

[0025] In order to minimize the noise generated during spring ejection, the right-side protective tube 31 and the left-side protective tube 32 are fitted with inner bushings for buffering. Polyurethane, nylon or rubber bushings are installed on the inner wall of the round tube to fundamentally eliminate the noise. The tube bodies of the right-side protective tube 31 and the left-side protective tube 32 are provided with irregular holes to promptly release the air shock waves and noise generated during the ejection of the spring and baffle. These multiple effective physical noise reduction measures are far superior to spraying noise reduction, solving the problems of tube wall resonance and shock waves at the source.

[0026] like Figure 1As shown, the right support 13 is equipped with a relief wheel assembly 2 connected to the protective pipe assembly 3. The relief wheel assembly 2 includes a right small relief wheel 1 21 and a right small relief wheel 3 23 rotatably connected to the outer wall of the right protective pipe 31 via a first rotating shaft. A right small relief wheel 22 and a right small relief wheel 4 24 are rotatably connected to the inner wall of the right support 13 via a second rotating shaft. A right large relief wheel 5 25 is rotatably connected to the front end of the right support 13 or the right side of the front support 11 via a third rotating shaft. On the outer wall of the left protective pipe 32, there are left small unloading wheels 6 26 and 8 28 arranged symmetrically with right small unloading wheels 1 21 and 3 23. On the inner wall of the left support 12, there are left small unloading wheels 7 27 and 9 29 arranged symmetrically with right small unloading wheels 2 22 and 4 24. On the front end of the left support 12 or the left side of the front support 11, there is left large unloading wheel 10 20 arranged symmetrically with right large unloading wheel 5 25.

[0027] like Figure 8 As shown, a pull rod assembly 5 is provided above the protective tube integration 3. The pull rod assembly 5 includes a card 1 53 and a card 2 54 fixedly connected to the top walls of the right protective tube 31 and the left protective tube 32. A pull rod 52 with an isosceles trapezoidal cross section is slidably connected below the card 1 53 and the card 2 54. A second grip 51 conforming to the ergonomic principle is fixedly provided at the rear end of the pull rod 52. A hanging tooth 55 is fixedly provided at the front end of the pull rod 52. A first return spring 56 connected to the protective tube wall is fixedly connected to the corresponding part of the front end of the hanging tooth 55. A rectangular hole is provided at the corresponding part of the pull rod 52.

[0028] like Figure 1 , Figures 9-10 As shown, an arrow groove plate is provided above the protective tube integration 3, and rectangular holes are provided in relevant parts of the arrow groove plate; an arrow body 4 is provided above the arrow groove plate, with a sharp triangular arrowhead. It is made of tungsten fiber / zirconium-based amorphous high-strength alloy composite material using 3D printing technology. This tungsten fiber / zirconium-based amorphous high-strength alloy composite material has ultra-high hardness and density, excellent toughness and self-sharpening ability, extremely strong structural strength and directional penetration, super rigidity that does not dull upon impact, and can increase the penetration depth of traditional tungsten alloy armor steel by more than 70%; a firing pin is provided at the front ⅓ of the arrow body 4, angled towards the tail. The arrow body 4 has a firing slot 42 and a tail fin 41 at its tail. The tail fin 41 has 3 pieces arranged in a triangular pattern of 1 on top and 2 on the bottom. It is made of a carbon-aluminum alloy hybrid material, which utilizes the high damping of carbon fiber and the stability of aluminum alloy to effectively absorb high-frequency vibration energy. The arrow body 4 has a flat and round structure with a thicker front and a thinner rear, and is equipped with multiple gas guide slots. The spring integrated assembly 6 includes a right connecting plate 63 and a left connecting plate 64 that are fixedly connected to the rear ends of the right protective tube 31 and the left protective tube 32, respectively. The right connecting plate 63 and the left connecting plate 64 are respectively fixedly connected to the inner walls of the right connecting plate 63 and the left connecting plate 64. The right spring 61 and the left spring 62 are respectively fixedly connected to the inner walls of the right connecting plate 63 and the left connecting plate 64.

[0029] It should be noted that the arrowhead design facilitates stress concentration; the design of the arrow body 4 breaks with traditional conventional wisdom, taking a different approach: First, to reduce air resistance and the ultra-high-speed attenuation after launch, the arrow body is designed as a flattened oval shape, thicker at the front and thinner at the back, which enhances the bending stiffness of the head, guides the smooth transmission of stress, and reduces the risk of standing wave superposition; second, the arrow body is designed with a carbon-aluminum alloy hybrid material structure, combining the high damping of carbon fiber and the stability of aluminum alloy, effectively absorbing high-frequency vibration energy; third, the arrow body is designed with multiple gas guide channels, which can significantly reduce air resistance and turbulence, which is conducive to the high-speed forward movement of the arrow body; fourth, the arrow body is coated with a coating containing rubber components or microparticles, which can slightly dissipate vibration energy; fifth, to improve the stability of the ultra-high-speed linear motion of the arrow body 4 after launch, the tail is designed with 3 tail fins; sixth, after the arrow body 4 is launched, when the arrowhead encounters a hard obstacle, due to the sudden obstruction, its huge dynamic acceleration and Inertial kinetic energy is instantly converted into potential energy. Combined with the arrowhead's super rigidity and impact-resistant properties, it possesses a special armor-piercing capability exceeding that of traditional tungsten alloy armor by over 70%. Seventh, a launch slot is located at the front ⅓ of the arrow body. The enormous launch kinetic energy originates from the front, not the tail, preventing hysteresis and lateral bending of the arrow body. It also prevents periodic oscillations around its center of gravity and avoids an "S"-shaped flight trajectory. Eighth, the three tail fins are arranged in a triangular pattern (2 below, 1 above), ensuring smooth and stable flight. Ninth, based on powerful test data for composite bows, every 10-pound increase in draw weight increases arrow speed by approximately 20-25 feet per second (fps). Using a 70-pound composite bow with an initial velocity of approximately 340 fps (104 m / s) as a benchmark, a 300-pound bow can achieve an initial velocity of 250 m / s or more. According to the kinetic energy formula E=½MV... 2 Calculations show that the kinetic energy could exceed 900 joules; furthermore, in high-altitude areas, the range can increase by 8 meters for every 1000-meter increase in altitude due to reduced air resistance. The higher the altitude, the faster the initial velocity and the greater the range, reaching or approaching the initial kinetic energy level of a small-caliber rifle bullet. The design and materials ensure the arrow's immense armor-piercing capability. If the 20% redundant elasticity is included, the range is even greater, and the armor-piercing power is even stronger.

[0030] like Figure 9As shown, one end of the spring integrated assembly 6 is provided with a launcher integrated assembly 8. The launcher integrated assembly 8 includes a right spring front connecting plate 81 fixedly connected to the front end of the right spring 61, and a left spring front connecting plate 86 integrally formed with the right spring front connecting plate 81 fixedly connected to the front end of the left spring 62. A vertical launch mounting plate 82 is fixedly provided at the middle of the front end of the right spring front connecting plate 81 and the left spring front connecting plate 86. An oblique support plate 84 and a forward extension plate 85 are provided at the front end of the vertical launch mounting plate 82. A trigger mounting slot 83 is provided at the corresponding part of the forward extension plate 85. 5 forms a hollow right-angled triangular space with the vertical firing plate 82 and the oblique support plate 84, so as to form the oblique support plate 84 to provide oblique support for the vertical firing plate 82; when the trigger plate 93 is inserted into the trigger slot 83 on the front extension plate 85, it prevents the upper part of the right spring front connecting plate 81 and the left spring front connecting plate 86 from tilting forward, maintains the balanced force of the right spring 61 and the left spring 62, and ensures that the elastic force is released smoothly and evenly when the spring is released, so that the right spring front connecting plate 81 and the left spring front connecting plate 86 do not collide with the protective tube integration 3.

[0031] In addition, multiple irregular holes are provided on the right spring front connecting plate 81 and the left spring front connecting plate 86 to avoid the shock wave effect generated by the baffle and spring when the left and right springs are released, thereby reducing the noise generated during launch. To further reduce noise, a 1-3mm thick high-damping sound-absorbing and vibration-damping noise-reducing coating is sprayed on the oblique support plate 84, the vertical launch hanging plate 82, and the forward extension plate 85 in front of the right spring front connecting plate 81 and the left spring front connecting plate 86. Relying on the viscoelastic properties of polymers, the mechanical vibration energy generated by the vibration of the baffle is converted into heat energy through the movement of molecular chains, directly suppressing metal resonance and reducing noise from the sound source. The inorganic fiber material of the coating is dispersed in the synthetic resin emulsion, and a porous film layer is formed after spraying, allowing the sound waves to be reflected and rubbed multiple times between the pores to achieve sound energy attenuation.

[0032] It should be noted that the spring integrated assembly 6 is a combination of multiple springs. According to the formula for calculating elastic force F=kx, and the relationship between wire diameter and elastic force K=(G... ) / (8 Then, the elastic force increases by a factor of four; doubling the wire diameter theoretically increases the elastic force by 16 times; the spring constant can be derived from the spring parameters: K = (G ) / (8 If NC), then the elastic force of the combined spring is calculated as the total spring constant K_parallel = K1 + K2 of the parallel springs. Then the deformation of each spring is equal, and the total elastic force is the sum of the elastic forces of each spring. When the spring is compressed and then released, the elastic force pushes the object to move. The elastic force does positive work, and the elastic potential energy is converted into the kinetic energy of the object, launching the arrow.

[0033] The right-side spring 61 and the left-side spring 62 are made of carbon fiber reinforced composite material (e.g., high-modulus carbon fiber, such as ≥T1000 winding process, which improves the attenuation rate by more than 35%), which has the strongest comprehensive mechanical properties among springs, with a specific strength far exceeding that of metals. They are fatigue resistant, lightweight, and suitable for scenarios requiring lightweight design and high elasticity limits. In use, they can achieve 10 6 For high-cycle applications exceeding 1 million cycles, its density is approximately 1 / 4 to 1 / 5 that of steel and 1 / 2 that of aluminum, while its strength is more than 5 times that of steel. It can reduce weight by 50% to 75% while maintaining the same stiffness, significantly reducing unsprung mass and improving equipment control response or energy efficiency. Under the same spring force output requirements, the spring weight can be greatly reduced, demonstrating significant lightweight advantages. It also exhibits strong corrosion resistance; the basic resin and carbon fiber have stable chemical properties, resisting acid, alkali, and salt spray corrosion, eliminating the need for electroplating or coating for rust prevention like alloy springs. It is adaptable to harsh and extreme environments and has a long service life. Furthermore, it possesses excellent damping and vibration reduction performance; the fiber interface within the composite material absorbs vibration and noise energy through friction with the matrix, resulting in faster attenuation during dynamic response, achieving or approaching a "silent" state.

[0034] Due to its high fatigue resistance potential and the near absence of the notching effect common in metal springs, it is suitable for long-term alternating load conditions. Under constant alternating loads, the fiber layup optimization technology in the design makes its fatigue life superior to some alloy steels, and it has no risk of metal fatigue crack propagation. It is suitable for high-frequency stress scenarios, and the interface between the fiber and the matrix can prevent crack propagation. Under high stress cyclic conditions, the elastic force decay rate is much slower than that of ordinary alloy springs, resulting in better elastic force stability over long-term use. To prevent carbon fiber springs from delamination or fracture due to brittleness or overload and to improve their plastic deformation buffering capacity, three main measures can be taken: matrix and interlayer toughening, optimized production process, and optimized engineering application. The core is to improve their toughness and damage resistance: First, adding suitable toughening agents to the resin matrix and laying nanofiber membranes between prepreg layers can improve the material's resistance to delamination and damage tolerance without increasing thickness or weight, reducing crack formation under impact; Second, strictly controlling the entire process of spinning, pre-oxidation, and carbonization of PNA raw materials can reduce defects such as pores, impurities, and surface grooves inside the fibers, reducing brittle fracture from the source. The probability of cracking is high; third, high-quality matching impregnating adhesive is selected, and a U-shaped anchoring process is used during construction to inhibit crack propagation; fourth, the number of carbon fiber cloth bonding layers is controlled to not exceed three, and carbon fiber plates are used instead for excess demand to avoid premature brittle failure; fifth, the stiffness of composite springs is highly dependent on the fiber layup angle. By adjusting the fiber layup direction, angle, and arrangement, anisotropic customization of performance can be achieved to meet specific stress requirements; sixth, it has high thermal stability, extremely low coefficient of thermal expansion, stable dimensions under temperature changes, virtually no deformation, and strong high-temperature creep resistance, close to zero or even negative, far exceeding most conventional metal springs.

[0035] To ensure the high armor-piercing capability of this invention, the total spring force is set at 300 psi (136 kg). To ensure the full compression resistance of the carbon fiber spring's plastic deformation buffering capacity, the spring force is redundantly designed, set at 360 psi (163 kg), exceeding the redundancy by 20%. To completely avoid noise during spring ejection, avoid the equipment excitation frequency, eliminate resonance noise, ensure a smooth and impact-free spring rebound, and further reduce the additional collision noise caused by lateral instability and friction against the pipe wall when the spring is compressed, according to the formula... After calculating the initial effective number of coils for the spring, 1.5 to 2.5 support coils are added to the initial value to make the spring's natural frequency deviate from the equipment's operating frequency by more than 15%, completely avoiding resonance. Simultaneously, the increased number of coils results in more even force distribution per coil, leading to a smoother rebound and significantly reducing impact noise during spring release. Following the GB / T1358 standard, the calculation results are rounded to half or full coils, with half coils being preferred to ensure more stable spring dynamics and further optimize noise reduction. By establishing a coupling model between the effective number of coils, stiffness, and dynamic characteristics, the optimal coil number range is determined, ultimately achieving noise reduction while increasing spring fatigue life by more than 40%. After calculation, the stiffness can be fine-tuned by adjusting the effective number of coils, ensuring the system's natural frequency avoids the equipment's operating excitation frequency, fundamentally reducing resonance noise. In addition, surface coating treatment is applied to the direct contact parts between the spring integrated assembly 6 and the right spring front connecting plate 81, the left spring front connecting plate 86, the bracket integrated assembly 1 and the protective tube integrated 3 to avoid metal carburization, carburization and electrochemical corrosion that may be caused by direct contact with metal.

[0036] like Figure 3 and Figure 5 As shown, a trigger assembly 9 extending downwards is provided inside the sheath integration 3. The trigger assembly 9 includes a trigger pivot 92 disposed on the inner wall of the sheath integration 3. The other end of the trigger pivot 92 is rotatably connected to a trigger body 91 extending downwards from inside the sheath integration 3. The upper end of the trigger body 91 has a trigger mounting plate 2 94 and a trigger mounting plate 1 93 integrally formed. The trigger mounting plate 1 93 and the trigger mounting plate 2 94 are bent at an acute angle and extend upwards into the internal cavity of the sheath integration 3. The trigger body 91 is designed as follows: The trigger body has a parabolic shape, with a vertically upward-curving trigger plate 94 at the end of the parabola. A slightly forward-curving trigger plate 93 is designed at the corresponding part of the upper end of the trigger plate 94. A second return spring 95 is connected to the trigger plate 94. A connection point for the second return spring 95 is provided on the side of the trigger body 91, and the other end of the second return spring 95 is connected to the side wall of the protective tube integration 3. In its natural state, the second return spring 95 pulls the trigger body 91, causing the trigger plate 93 to extend into the trigger latch 83. Additionally, a protective frame surrounds the trigger body 91 to protect it from accidental disturbance, and a first grip 10 is located close to the outside of the protective frame.

[0037] like Figure 1 and Figure 11 As shown, the unloading wheel integrated assembly 2 is provided with an unloading wheel assembly 110. The unloading wheel assembly 110 includes small ball bearings 111 disposed inside the right small unloading wheel 1 21, right small unloading wheel 22, right small unloading wheel 3 23, right small unloading wheel 4 24, left small unloading wheel 6 26, left small unloading wheel 7 27, left small unloading wheel 8 28 and left small unloading wheel 9 29. The small ball bearings 111 are made of carbon fiber reinforced composite material. The right large unloading wheel 5 25 and the left large unloading wheel 10 20 are both provided with large ball bearings and unloading wheels 112. The large ball bearings are also made of carbon fiber reinforced composite material.

[0038] It should be noted that carbon fiber reinforced composite materials can significantly improve rigidity and compressive strength, are extremely lightweight, have a very low coefficient of thermal expansion, good dimensional stability, are wear-resistant, have a longer lifespan, a high coefficient of friction, are corrosion-resistant, and are suitable for special working conditions. They utilize the high rigidity of carbon fiber and the extremely low noise of ball bearings during rotation. The unloading wheels are made of lightweight engineering plastic, and their rigidity can be improved by filling with glass fiber / carbon fiber. Utilizing the self-lubricating properties of engineering plastics, no additional oiling is required, resulting in low maintenance costs. They can be injection molded, leading to low mass production costs. They offer flexible design, are maintenance-free, resistant to chemical corrosion, and can operate quietly. The 10 sets of unloading wheels are designed for a total unloading force of 163kg (360 lbs), which can unload more than 90% of the spring force generated when the spring is fully compressed, ensuring that it can be used by people with average physical strength and has extremely strong backup capabilities.

[0039] like Figure 1 As shown, the unloading tie rod 121 passes sequentially over the right small unloading wheel 1 21, right small unloading wheel 22, right small unloading wheel 3 23, right small unloading wheel 4 24, right large unloading wheel 5 25, left large unloading wheel 10 20, left small unloading wheel 9 29, left small unloading wheel 8 28, left small unloading wheel 7 27, and left small unloading wheel 6 26. When stationary, the unloading tie rod 121 rests close to the front of the vertical launch plate 82. The unloading tie rod 121 is made of ultra-high molecular weight polyethylene (UHMWPS), such as Dyneema or Spectra series, which is 15 times stronger than steel, wear-resistant, and has low elongation, making it the first choice for making high-poundage tie rods. Alternatively, a hybrid weaving structure of "core layer + outer layer" can be used: the core layer uses Dyneema to provide strength, and the outer layer is protected by wear-resistant materials. The problem of super tension is solved by a custom weaving method that increases the number of strands (≥100 strands) to improve the overall load-bearing capacity.

[0040] like Figures 12-18As shown, the night vision thermal imaging sight is mounted on the upper rear of the protective tube integration 3 via a mount; this infrared night vision thermal imaging sight first uses a power transmission protection circuit to suppress and protect against abnormal fluctuations and noise, transient overvoltage and surge current, and improve the electromagnetic compatibility of the circuit (e.g. Figure 13 (as shown) and the charging rectifier circuit perform intelligent charging of the battery (as shown) Figure 14 As shown), it detects the infrared radiation emitted by an object to achieve imaging; it adopts passive (thermal imaging) technology, which does not emit infrared rays itself, but uses a thermal element to detect the temperature difference or radiation difference between the target and the background to directly capture the infrared radiation of the target itself. The signal processing unit performs uniformity correction and image processing (noise reduction, contrast enhancement) on the electrical signal to improve and optimize the signal quality; through display devices such as OLED displays, the processed signal is presented as images of different colors, and the intensity of the colors reflects the intensity of the infrared radiation; the device receives (such as...) Figure 15 As shown), photoelectric conversion (such as...) Figure 16 As shown), image enhancement (such as...) Figure 17 (as shown) and image display (such as) Figure 18 The process involves four steps (as shown) to convert weak nighttime light signals into electrical signals and use image display technology to provide clear and visible images, enabling accurate shooting even in adverse weather conditions such as darkness, rain, snow, fog, haze, and sandstorms.

[0041] In actual use, the operator holds the first handle 10 with the left hand and the second handle 51 with the right hand, and pulls the lever 52. At this time, the rectangular hole on the lever 52 slides over both sides of the vertical firing plate 82. Because the unloading string 121 is close to the vertical firing plate 82, the hook teeth 55 on the lever 52 simultaneously hook the unloading string 121, the right spring front connecting plate 81 and the left spring front connecting plate 86. Relying on the unloading force of the unloading string 121 and the 10 sets of unloading wheels of the unloading wheel integrated assembly 2, the right spring front connecting plate 81 and the left spring front connecting plate 86 are easily pulled, compressing the right spring 61 and the left spring 62 to the full pressure state. At this time, the trigger hook plate 93 passes through the rectangular hole on the lever and the rectangular hole on the arrow slot plate, and fits into the trigger hook 83 on the front extension plate 85.

[0042] Then, push the lever 52 forward. The lever 52 smoothly resets under the action of the first return spring 56, pushing the arrow body 4 into the arrow slot and the launch mount 42 onto the vertical launch mount 82. The night vision thermal imaging sight 14 locks onto the relevant part of the target. Pull the trigger body 91. Simultaneously, the trigger mount 94 slides downward along the trigger pivot 92, and the parabolic surface of the relevant part of the trigger body 91 quickly pushes the extension plate 85 upward. The trigger mount 93 quickly disengages downward from the trigger mount 83. At the instant the right spring 61 and the left spring 62 pop out, the arrow body 4, mounted on the vertical launch mount 82, is launched at high speed. Release the trigger body 91, which resets under the action of the second return spring 95. Another function of the second return spring 95 is to hold the trigger body 91 in place to prevent it from slipping out of the trigger mount 83. If it is necessary to eliminate other targets, repeat the above launching action.
