Description

Technical Field

[0001] The invention relates to an infrared thermal imaging bulletproof target, in particular to an infrared thermal imaging target for performing shooting training on a target with thermal infrared characteristics by using an infrared sight during shooting training. Background Art

[0002] When the military conducts night shooting training, they usually use a light that flashes continuously to indicate the target to the trainees. The light usually uses a flashlight bulb or LED light, and the shooter aims at the target point through the flashing light. The main purpose of this night shooting training is to simulate shooting at enemies who use lighters and smoke on the battlefield.

[0003] With the development of military technology, infrared thermal imaging equipment has been widely used in military reconnaissance. In several regional wars in modern times, the US military relied on its significant advantages in infrared thermal imaging technology to fight only night battles against countries with backward technology and lack of night vision equipment and thermal imaging equipment, making the war an asymmetric war that is one-way and transparent to the US military.

[0004] In recent years, with the rapid development of my country's military technology, infrared night vision devices, infrared sights and other equipment have been equipped in large quantities to the troops. However, there has been no mature, reliable, simple and practical technical solution for infrared thermal imaging targets used in infrared sight training.

[0005] The known existing infrared thermal imaging targets use the method of converting electrical energy into thermal energy to heat the target, so that the target has infrared thermal imaging characteristics and can be identified by infrared sights. This includes: installing a resistance wire on the target and supplying power to the resistance wire to make it heat up; or supplying power to the target coated with conductive paint or graphene to make the conductive paint or graphene heat up, etc. However, whether it is a resistance wire or graphene, it is easy for a bullet to break the cable, causing the positive and negative poles to be disconnected and lose heat. Summary of the invention

[0006] The idea of ​​the present invention is to use a bulletproof target plate that can prevent bullets from penetrating, and place the heating element and the battery at the rear side of the bulletproof target plate to solve the problem of the positive and negative poles being disconnected and losing heat due to the bullet breaking the cable. The technical solution of the present invention is: an infrared thermal imaging bulletproof target, which is composed of a bulletproof target, a heating element, and a battery; the bulletproof target is made of bulletproof material and can prevent small arms bullets from penetrating; the heating element is located at the rear side of the bulletproof target, and when connected to the battery, it generates heat and transfers the heat to the bulletproof target. The bulletproof target has a fixed frame at the rear side. The heating element has a back plate at the rear side. There is also a heat insulation layer between the heating element and the back plate. There is also a heat conductive layer between the bulletproof target and the heating element. The 10-ring bull's eye position on the bulletproof target is affixed with a bull's eye heat insulation sticker. There is a battery box on the back plate. There is a bull's eye hole on the heating element. There is a bull's eye area on the heat conductive layer. There is a mounting frame at the rear side of the bulletproof target.

[0031] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Compare with Figure 1 , Figure 1 It is a right front stereoscopic exploded view of one of the embodiments of the present invention. In the figure, 1 is a bulletproof target in the shape of a chest ring target, which is made of bulletproof material and can block penetration by small arms bullets; in each embodiment of the present invention, a chest ring target is used as an example target shape of the bulletproof target 1. Obviously, it is also applicable to various target shapes such as circular ring targets, head targets, half-body targets, and human body part targets. The heating element 2 shown in the figure is a thin film structure heating film, which generates heat when connected to the battery 4; because the heating film is located on the rear side of the bulletproof target 1 and is attached to the bulletproof target, its heat will be transferred to the bulletproof target 1, causing the temperature of the bulletproof target 1 to rise accordingly, thereby simulating the human body temperature, so that soldiers using infrared thermal imaging sights can identify targets with temperatures higher than the ambient temperature from the sights, and conduct shooting training of infrared thermal imaging targets. From Figure 1It can be seen that in the middle of the heating film of the thin film structure, there is a bull's eye hole 3 in the area corresponding to the target 10 rings. The bull's eye hole 3 is a hole cut at the position of the heating film and the bull's eye or 10 ring area of ​​the corresponding target. Its purpose is to form a low temperature zone in the bull's eye or 10 ring area of ​​the bulletproof target 1 to facilitate soldiers to accurately aim at the bull's eye or 10 rings.

[0033] Compare with Figure 2 , Figure 2 1 is a left rear perspective view of one embodiment of the present invention. Figure 1 A three-dimensional diagram of the appearance after the various components are assembled together. As can be seen from the figure, the heating element 2 and the battery 4 are located at the rear side of the bulletproof target 1. Since the bulletproof target 1 is made of bulletproof material, it can prevent the penetration of small arms bullets. Therefore, the heating element 2, the battery 4 and the necessary temperature control electronic components, wires, etc. (conventional technology known to those skilled in the art, not shown in the figure) are very safe at the rear side of the bulletproof target 1 and will not be damaged by bullets. Obviously, this technical solution has well solved the problem that the infrared thermal imaging target needs to provide power and heat for the target, but cannot overcome the problem that bullets break the wires and damage the heating element.

[0034] The heating element 2 in one of the above embodiments adopts a heating film. The common heating film technology is a graphene conductive film, which is a material with high production cost and relatively expensive price.

[0035] Next, we further propose a technical solution for a heating element with mature technology and low price.

[0036] Compare with Figure 3 , Figure 3 It is a left rear stereoscopic view of the second embodiment of the present invention. Figure 3 The plan and Figure 2 The scheme shown is basically the same, except that the heating element uses a very cheap heating wire 5 to replace the expensive heating film. Figure 3 It can be seen that on the rear side of the bulletproof target 1 , we have dispersedly arranged the heating wires 5 in a spiral shape along the shape of the target, and the heating wires 5 are powered by the battery 4 . Obviously, the heating wires 5 can also increase the temperature of the bulletproof target 1 .

[0037] Since the bulletproof target 1 is made of bulletproof materials, commonly used bulletproof materials include high-strength bulletproof steel plates or ceramics. In order to achieve a good bulletproof effect, the weight of the material is relatively heavy. It is necessary to better fix the heating element 2, battery 4 and other components on the back side of the heavier bulletproof steel plate, and to ensure that the heating element 2 and battery 4 are firm and not damaged during frequent transportation, storage and use. The technical solutions of the above-mentioned embodiments one and two need to be further improved.

[0038] Compare with Figure 4 , 5 , 6, 7, Figure 4 It is a left rear perspective exploded view of the third embodiment of the present invention. Figure 5 is a left rear stereogram of the third embodiment of the present invention, Figure 6 It is a right front side stereoscopic exploded view of the third embodiment of the present invention, Figure 7 This is a right front perspective view of the third embodiment of the present invention. This embodiment proposes a sufficient and complete technical solution. Figure 4 , Figure 6 The exploded diagrams in the front and back directions gradually explain the specific implementation method:

[0039] First, in this embodiment, a fixed frame 6 is added as shown in the figure, respectively Figure 4 , Figure 5 , Figure 6 The fixing frame 6 is a frame welded to the rear side of the bulletproof target 1, which is used to fix and protect various components including the heating element. At the same time, since the bulletproof target 1 is heavy, how to place it on the target stand for shooting is also a problem that needs to be considered. Therefore, two square steels are welded on the left and right sides of the fixing frame 6. When installing the target, the target rod can be directly inserted into these two square steels. Here, we call these two square steels used to install the target on the target rod mounting frames 7. It can also be seen from the figure that the left and right sides of the fixing frame 6 each share a mounting frame 7, which together form an annular frame consistent with the outer contour of the bulletproof target. Since this annular frame is directly welded to the back of the bulletproof target 1, it forms a whole with the bulletproof target, so that it can play a good role in fixing and protecting the components such as the heating element placed inside it. In this embodiment, the heating element still uses the heating wire 5. In order to protect the heating wire 5, the control Figure 4 , Figure 5 , Figure 6 It can be seen that a back plate 8 is further added in this embodiment. After the back plate 8 is combined with the fixing frame 6, a closed cavity is formed. The heating wire 5 is located in the cavity and can be well protected.

[0040] Secondly, in order to effectively store the heat of the heating wire 5 to save electricity, an insulation layer 9 is added between the heating wire 5 and the back plate 8. The moisture-retaining layer can be made of a lightweight and soft insulation material to prevent the heat of the heating wire 5 from dissipating through one side of the back plate.

[0041] Thirdly, since the heating wire 5 is a linear heating element arranged in a spiral shape, the heat is diffused and transferred from the heating wire to both sides, and the heat distribution is bound to be uneven. Although the bulletproof target 1 is usually a good conductor of heat and has a large thickness, it has the ability to fully absorb heat and evenly distribute the heat, but whether it is steel or ceramic, its thermal conductivity is still relatively low. Therefore, in comparison with the attached Figure 4 , Figure 6 It can be seen that a heat-conducting layer 10 is provided between the bulletproof target 1 and the heating wire 5. The heat-conducting layer 10 is made of a material with excellent thermal conductivity, such as an aluminum plate. The heating wire 5 is mounted on the heat-conducting layer 10, and the heat-conducting layer 10 is mounted on the back of the bulletproof target 1. Due to the high thermal conductivity of the heat-conducting layer 10, the heat of the heating wire 5 can be quickly and evenly dispersed to the entire heat-conducting layer 10, and then transferred to the bulletproof target 1 through the heat-conducting layer 10, thereby obtaining a relatively uniform heat distribution on the entire target surface of the bulletproof target 1. Similarly, in contrast Figure 4 , Figure 6 It can be seen that in the middle of the heat-conducting layer 10, there is a bull's eye area 11 corresponding to the target 10 rings. The bull's eye area 11 is a hole cut at the position of the heat-conducting layer 10 and the bull's eye or 10 ring area of ​​the corresponding target. Its purpose is to form a low temperature area in the bull's eye or 10 ring area of ​​the bulletproof target 1 to facilitate soldiers to accurately aim at the bull's eye or 10 rings.

[0042] Further, in order to make the target shape of the bulletproof target 1 more visual and to make the low temperature area of ​​the bull's eye or the 10-ring area more clear and obvious, the reference Figure 4 , Figure 6 It can be seen that in front of the bulletproof target 1, a target paper 12 is also attached, and there are clear target shapes, target rings, ring number marks and bull's-eye 10-ring area 13 on the target paper 12. When the target paper 12 is attached to the bulletproof target 1, the target shape of the bulletproof target 1 becomes clearer and more specific. Further, as shown in the figure, by attaching a bull's-eye heat insulation sticker 14 of the same size as the 10-ring area 13 at the position of the 10-ring area 13, the bull's-eye heat insulation sticker 14 is made of heat insulation material, so that a 10-ring low-temperature area with clearer boundaries can be formed in the 10-ring area of ​​the bulletproof target 1, which can be clearly presented in the infrared thermal imaging sight, so that the soldier can accurately aim at the bull's-eye or 10 rings when shooting.

[0043] Further, in order to facilitate charging or replacing batteries, refer to the attached Figure 4 , 5As can be seen from Figure 6, a battery box 15 is provided on the rear side of the back plate 8. The battery 4 uses a power bank-style rechargeable battery 4, which is placed in the battery box 15. At this time, a standard Type-C power interface can be provided on the back plate 8, and the battery 4 of the power bank is used to power the heating wire 5 through a standard Type-C connection line. Furthermore, since the heating wire 5 is sealed inside the fixed frame 6 via the insulation layer 9 and the back plate 8, on the one hand, in order to prevent the temperature of the heating wire 5 from being too high, and on the other hand, in order to save electricity, it is necessary to further design a power supply circuit including a temperature control chip for the heating wire 5. When the temperature of the heating wire 5 is higher than the set value, the power will be automatically cut off, and when the temperature drops to the set value, the power will be automatically supplied again, so that the temperature of the bulletproof target 1 is always within the range of technical requirements. The above-mentioned Type-C power interface, Type-C connecting cable, and power supply circuit including temperature control chip are common technologies well known to technical personnel in this field and will not be described in detail here. The relevant interfaces, circuits, and wires are not drawn in the accompanying drawings. For technical personnel in this field, these interfaces, circuits, and wires are well known and obvious, and do not affect the implementation of the solution or the integrity of the solution.
