Description

Technical Field

[0001] This utility model relates to the field of infrared simulation technology, specifically to an infrared emitting device for a decoy target. Background Technology

[0002] Infrared simulation technology plays a crucial role in modern military training, tactical confrontation, and target deception. The infrared transmitter, as the core carrier of this technology, is an electronic device capable of actively emitting infrared radiation of a specific wavelength. By simulating the thermal radiation characteristics of real military targets (such as tanks, armored vehicles, and aircraft) in the infrared band, it can generate thermal signals highly similar to real targets within the field of view of enemy infrared reconnaissance systems or guided weapons, thereby achieving the purposes of deception, interference, or training testing.

[0003] Decoy targets, also known as simulated targets or lure targets, are devices or models that mimic real military targets in terms of shape, size, and some electromagnetic characteristics (such as infrared and radar wave reflection). They are widely used in combat training to enhance battlefield realism or deployed at the tactical front to confuse enemy reconnaissance and deplete their precision-guided munitions. Among them, tank decoys are one of the most common and representative types of ground decoys. They not only need to have a realistic visual appearance but also need to simulate the unique infrared radiation characteristics of real tanks in operation or at rest to counter increasingly advanced infrared thermal imaging reconnaissance and infrared-guided threats.

[0004] Currently, infrared signature simulation devices applied to decoy targets, especially decoy tanks, still have several obvious limitations and areas that urgently need improvement in terms of technical implementation, mainly including: The realism and adaptability of infrared signature simulations are insufficient. Many existing devices use infrared radiation sources with fixed power and fixed wavelengths, emitting infrared signals with a single spectrum, unadjustable intensity, or limited adjustment range. This makes it difficult to accurately match the dynamically changing infrared signatures of different tank models under various operating conditions (such as engine operation, shutdown cooling, and ambient temperature changes), especially in simulating detailed features such as exhaust heat sources and temperature differences between different parts of the vehicle body during target movement. These features are easily detected by intelligent infrared reconnaissance systems with pattern recognition capabilities. The infrared radiation source and auxiliary heating elements added to enhance simulation realism generate a large amount of heat during operation. Existing devices often have rudimentary heat dissipation designs, relying solely on natural convection or a few ventilation holes, resulting in low heat dissipation efficiency. Under prolonged continuous operation or high-temperature environments, severe heat accumulation inside the device can lead to not only wavelength drift and output power attenuation of the infrared radiation source, affecting the stability and accuracy of the simulated signal, but also accelerate the aging of electronic components and even cause overheating shutdown, severely restricting the reliability of the device and its ability to simulate continuous field combat. Traditional devices often rigidly fix infrared emission, control, power supply, and heat dissipation modules within a single housing, resulting in a bulky structure and difficult disassembly and assembly. The power module cannot be quickly replaced, limiting continuous power supply in the field; optical windows or filters are difficult to clean or replace after contamination or damage; overall maintenance or upgrades require specialized tools and skilled technicians, which is time-consuming and labor-intensive, making it difficult to meet the practical requirements of rapid deployment and rapid support in field conditions. Utility Model Content

[0005] The purpose of this invention is to provide an infrared emitting device for a decoy target to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: This invention provides an infrared emitting device for a decoy target, including a housing. Inside the housing are an infrared emitting component, a main control board, a power supply component, and a heating component. The power supply component is located at the rear of the housing. The main control board is located on one side of the heating component and is fixedly connected to one side inside the housing. The infrared emitting component includes an infrared radiation source, a heat-conducting lens, and an infrared matching filter. The infrared radiation source is located at the upper end of the main control board, and four infrared emission holes are opened at the top of the infrared radiation source. A heat-conducting lens is fixed on each infrared emission hole, and an infrared matching filter is located above the heat-conducting lens, with the top of the infrared matching filter located on one side of a heat dissipation hole at the upper end of the housing. The infrared emitting component, projection component, and heating component are all signal-connected to the main control board, and the power supply component is electrically connected to the main control board.

[0007] As described above, a heat dissipation hole is provided on one side of the upper end of the housing, a cooling fan is provided on the right side of the housing, and air outlets are provided on both sides of the cooling fan.

[0008] As described above, the power assembly is connected to the rear of the housing by a snap-fit, and its rear is inserted into the housing. The power assembly includes a charging port and a power quick-release grip. The charging port is located at the center of the front end of the power assembly, and the power quick-release grip is located below the charging port.

[0009] As described above, a projection assembly is provided on the front of the housing. The projection assembly includes a projection lens and a projection camera. A snap-fit ​​groove is provided on the inner side of the front of the housing. A quick-release buckle is provided on the outer ring of the projection lens near the inner side of the front of the housing. The projection lens is engaged with the snap-fit ​​groove through the quick-release buckle. The projection camera is located in the middle of the main control board and the projection lens.

[0010] As described above, the bottom of the housing has four parallel supports.

[0011] As described above, the heating element is fixedly connected to the tail of the power supply element, and the heating element is signal connected to the main control board.

[0012] Compared with the prior art, the beneficial effects achieved by this utility model are: By incorporating an infrared emitting component that integrates an infrared radiation source, a thermally conductive lens, and an infrared matching filter, and intelligently controlled by the main control board, it can precisely generate and dynamically adjust infrared radiation signals in specific bands. This design not only filters out non-feature stray light and outputs infrared signals with a clean spectrum, but also simulates the dynamic thermal characteristics of targets under different operating conditions, significantly improving the realism and scene adaptability of infrared simulation, and effectively countering enemy intelligent infrared reconnaissance. By creating heat dissipation holes in the upper housing and integrating a cooling fan on the side, along with air outlets on both sides, a highly efficient forced convection cooling system is formed. This system can quickly dissipate the large amount of heat generated by the infrared radiation source and heat-generating components, effectively preventing performance degradation, signal distortion, or equipment failure caused by overheating of core components, and ensuring the stability and reliability of the device during long-term continuous operation and in high-temperature environments; The power supply unit is connected via a tail clip and features a quick-release grip for rapid battery replacement; the projection lens engages with the front of the housing via a dedicated quick-release clip, allowing for manual installation and removal. This modular design greatly simplifies the maintenance, replacement, or upgrade of critical components, significantly reducing the difficulty and time cost of field support and meeting the needs of rapid deployment and continuous operation in combat environments.

[0015] See Figure 1 This utility model provides a technical solution: an infrared emitting device for a decoy target, including a housing 1. A heat dissipation hole 12 is provided on one side of the upper end of the housing 1. The heat dissipation hole 12 is used to help dissipate heat from inside the device to the outside, and works with a cooling fan 8 to improve the overall heat dissipation efficiency. The front of the housing 1 is provided with a projection component 3. A snap-fit ​​groove is provided on the inner side of the front of the housing 1. The projection component 3 is snapped into the inside of the front of the housing 1 by a quick-release buckle. The snap-fit ​​allows for quick disassembly and installation of the projection component 3, which is convenient for future maintenance or replacement. The projection component 3 includes a projection lens 31 and a projection camera 32. The projection lens 31 is connected to the snap-fit ​​groove by a lens quick-release buckle 33. The projection camera 32 is located in the middle of the main control board 6 and the projection lens 31, and the projection camera 32 is parallel and aligned with the projection lens 31.

[0016] A cooling fan 8 is provided in the middle of the right side of the housing 1. The cooling fan 8 is electrically connected to the power supply component 4. Air outlets 11 are provided on both sides of the cooling fan 8. The air outlets 11 are used to exhaust the hot air inside the device guided by the cooling fan 8 to the outside, forming a cooling air circulation inside the device to ensure that each component works at a suitable temperature. The rear of the housing 1 is provided with a power supply assembly 4, which is used to provide stable operating power to the internal components such as the infrared emitting assembly 2, the projection assembly 3, the main control board 6, and the heating assembly 5. The bottom of the housing 1 has four parallel brackets 7. The brackets 7 can be placed directly or installed on the surface of the dummy target tank. They are used to support the device to achieve independent and stable placement or to adapt to the installation interface on the surface of the dummy target tank, so as to complete the firm deployment of the device on the dummy target. The housing 1 contains an infrared emitting component 2, a main control board 6, and a heating component 5. The heating element 5 is fixedly connected to the tail of the power supply element 4, and the heating element 5 is connected to the main control board 6 via signal. The power assembly 4 is connected by a snap-fit, and its tail is inserted into the housing 1. A charging port 41 is provided at the center of the front end of the power assembly 4. A power quick-release handle 42 is provided below the charging port 41. The charging port 41 is used to connect an external charging device to replenish the working power of the battery pack in the power assembly 4. The power quick-release handle 42 is used to easily pull to release the snap-fit ​​lock between the power assembly 4 and the housing 1, so as to realize the quick disassembly and replacement of the power assembly 4. A main control board 6 is provided on one side of the heating component 5. The main control board 6 is fixedly connected to one side inside the housing 1. The main control board 6 is used to receive and process the working signals of each functional component, coordinate the operating status of the infrared emitting component 2, the projection component 3, and the heating component 5; and at the same time, monitor and manage the power supply voltage, power, and other conditions of the power supply component 4 in real time. The infrared emitting component 2 includes an infrared radiation source 21, a heat-conducting lens 22, and an infrared matching filter 23. The infrared radiation source 21 is located at the top of the main control board 6. Four infrared emission holes are opened at the top of the infrared radiation source 21. The heat-conducting lens 22 is fixed on the infrared emission holes. The infrared matching filter 23 is located above the heat-conducting lens 22. The top of the infrared filter is located on one side of the heat dissipation hole 12 at the top of the housing 1. In the infrared emitting component 2, the infrared radiation source 21 receives control commands from the main control board 6 and generates infrared radiation signals of the corresponding band. The heat-conducting lens 22 conducts the heat generated by the infrared radiation source 21 during operation while allowing the infrared radiation signal to pass through, thus preventing the radiation source from overheating and being damaged. The infrared matching filter 23 is used to filter the stray band signals generated by the infrared radiation source 21, so that the emitted infrared signal matches the infrared characteristic band corresponding to the false target. Finally, it can accurately simulate the infrared radiation characteristics of the false target and improve the deception of the false target by infrared detection methods. The infrared emitting component 2, the projection component 3, and the heating component 5 are all connected to the main control board 6 by signal, and the power supply component 4 is electrically connected to the main control board 6.

[0017] Working principle: The infrared emitting device's core function is to simulate the infrared radiation characteristics of false targets, such as fake tanks. First, the power supply component 4, after being charged via charging port 41, is secured to the rear of the housing 1 by a clip. Upon startup, it supplies stable power to components such as the main control board 6, infrared emitting component 2, and heating component 5. For quick power replacement, the clip can be released via the power supply quick-release handle 42. Subsequently, the main control board 6, as the core control unit, monitors the power supply voltage and remaining power of the power supply component 4 in real time. It also sends precise operating signals to the infrared emitting component 2, heating component 5, and projection component 3 according to preset programs or external commands, coordinating the operating parameters and rhythm of each component. Next, the infrared emitting component 2 starts working: the infrared radiation source 21 receives commands from the main control board 6 and generates an infrared radiation signal in a band matching the false target. The heat-conducting lens 22 synchronously conducts the heat from the infrared radiation source 21 during operation to prevent overheating and damage, while ensuring unobstructed transmission of the infrared radiation signal. The infrared matching filter 23 filters out... The stray band signal generated by the infrared radiation source 21 ensures that the final emitted infrared signal accurately matches the infrared characteristics of the false target, ensuring that the enemy's infrared detection equipment identifies the signal that matches the attributes of the false target. During this process, the heat generated by the device operation from the heat-generating component 5 and the infrared radiation source 21 is guided by the cooling fan 8 to the air outlets 11 on both sides, and combined with the heat dissipation holes 12 at the top of the housing 1 to form an airflow circulation, quickly expelling the internal heat to maintain the components at a suitable operating temperature. In addition, the bracket 7 at the bottom of the housing 1 can directly support the device for independent and stable placement, or it can be adapted to the surface interface of the false target tank for secure deployment. At the same time, the projection component 3 can be quickly installed and removed through quick-release buckles, projecting the corresponding appearance in front of the device according to the simulated false target, thereby simulating the visual characteristics of the false target and forming a dual camouflage effect of visual + infrared with the infrared signal. Ultimately, the device continuously and stably emits infrared signals that match the false target and presents the corresponding appearance, achieving the function of confusing the enemy's infrared detection and visual reconnaissance, and camouflaging the false target.
