Infrared thermal imaging target

Abstract

An infrared thermal imaging target is composed of a target body and a target plate, the target body is made of a good thermal conductor material, the target plate is made of a poor thermal conductor material, and the target body is installed on the target plate. Holes are cut in the 10-ring target center area of the target, a window hole used for containing the spontaneous heating material bag is cut in the target plate, when the infrared thermal imaging sighting telescope is used for shooting training, the spontaneous heating material bag is placed on the back face of the target through the window hole, and the spontaneous heating material bag releases heat through oxidation reaction and transmits the heat to the whole target. Due to the fact that the 10-ring target center area is cut into the holes, heat cannot be transmitted to the hole area, the thermal infrared characteristic that the temperature is lower than the temperature of the target is shown in the infrared thermal imaging sighting telescope, and the thermal infrared characteristic is shown in the infrared thermal imaging sighting telescope. Therefore, the target is a shooting training target for indicating a thermal infrared target for a shooter who carries out shooting training by using the infrared thermal imaging sighting telescope.

Description

Technical Field

[0001] This application relates to an infrared thermal imaging target, especially an infrared thermal imaging target used when soldiers use an infrared thermal imaging sight to conduct shooting training on a target with thermal infrared characteristics during military shooting training. Background Art

[0002] There is a known self-heating material pack that uses a chemical heating agent to come into contact with oxygen, undergo a chemical reaction, and release heat, and is preserved through sealed oxygen isolation packaging. Due to its simple production, convenient carrying, low price, and ease of use, it has been widely used and is more popular among people in cold regions and those engaged in fieldwork. Its formula mainly includes: reduced iron powder, activated carbon, salt, water, etc. By mixing the components in the above composition evenly under vacuum or nitrogen protection according to the measurement, and then bagging and sealing for oxygen isolation preservation. Since the contact between oxygen in the heating agent and the formula materials is the key to heat generation, different contact situations result in different heat generation conditions. In the best case, the heat generation duration can reach up to 24 hours, and the maximum temperature can reach 74°C. The products made from these materials can be used for temporary heating when traveling or working and living in cold regions. (The above information source: Baidu Encyclopedia)

[0003] In the application titled "Technical Implementation Method of an Infrared Thermal Imaging Precision Target" with the application number 202311697296.2 submitted by the inventor of this application on December 12, 2023, a method was disclosed. A target is made of a good thermal conductor material, a hole is cut at the center of the target or the aiming point of the target, and one or more self-heating material packs are placed on the back of the target, in the non-hole area. The heat released by the chemical reaction of the self-heating material pack is transferred to the entire target by using the good thermal conductor material, so that the entire target presents a thermal infrared characteristic with a temperature higher than the surrounding environment temperature in the infrared thermal imaging sight. At the same time, since the target center or the aiming point is cut into a hole, the heat cannot be transferred to the hole area, presenting a thermal infrared characteristic with a temperature lower than the target temperature in the infrared thermal imaging sight, thus indicating the shooting target for the shooter using the infrared thermal imaging sight.

[0004] The patent of the application titled "A Thermal Imaging Target for Aiming Practice" with the application number 202421128539.0 submitted by the inventor of this application on May 22, 2024, disclosed a thermal imaging target for aiming practice, which is an earlier technical solution of this application.

[0005] The patent application of "A Reusable Self-Heating Infrared Thermal Imaging Precision Target" with the application number 202410832832.3 submitted by the inventor of this application on June 26, 2024, discloses a reusable self-heating infrared thermal imaging precision target, which consists of a target, a self-heating material package, and a target board; there is a aiming point on the target, the target is placed on the target board, there is a window hole on the target board, the self-heating material package is placed in the window hole, there is a backboard on the back of the target board, and there is a lifting opening on the backboard. When in use, open the lifting opening, put the self-heating material into the window hole. When the use is completed or the self-heating material fails, clean the self-heating material in the window hole and put in a new self-heating material to achieve reuse.

[0006] This application is based on the aforementioned patent 202421128539.0, combines the advantages of the technical solutions of the two patents 202311697296.2 and 202410832832.3, and takes the patent 202421128539.0 as the priority document to propose this application.

[0007] In addition, the prior art that this application will also use includes: hook and loop fastener (common names: Velcro, adhesive tape, mother and son buckle, etc.), which is a mechanical fastener system composed of two-sided fiber materials. One side is a densely arranged small hook-like structure (hook surface), and the other side is a fluffy looped fiber (loop surface). Through pressing contact, the hook surface and the loop surface wind around each other to form a temporary fixation, and an external force needs to be applied to peel them off when separating. Its core structure consists of a hook surface and a loop surface. The hook surface is usually made of hard nylon or polyester, and the surface is covered with micro-hook-like protrusions. The loop surface is usually woven from soft fibers into a looped structure to form a non-adhesive mechanical bite with the hook surface. Summary of the Invention

[0031] To make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0032] It should be noted that in the subsequent descriptions, the terms "front", "rear", "front side", "back side", "upper", "lower", "left", "right", "directly above", "lower left", "lower right", "inside", "outside", "around", etc. may involve the orientation or positional relationship indicated based on the orientation or positional relationship shown in the accompanying drawings. This is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the components referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0033] In addition, unless otherwise clearly specified, terms such as "installation", "connection", "adhesion", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or a combination, fitting, or gluing together, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0034] The accompanying drawings of the embodiments of this application are all illustrated using the commonly used chest ring target in the military. Obviously, this technical solution is equally applicable to target types such as head targets, half-body targets, hostage targets, and human body part targets that are often used in military shooting training. This is obvious to those skilled in the art, and will not be exemplified one by one in this application and its accompanying drawings.

[0035] Contrast the attached Figure 1 , Figure 1 is an exploded view of one of the embodiments of this application. In the figure, 1 is the target, 3 is the target board, and 5 is the self-heating material package. The infrared thermal imaging target is composed of the target 1 and the target board 3. The target 1 is made of a material that is a good conductor of heat, and the target board 3 is made of a material that is a poor conductor of heat. The target 1 is installed on the target board 3, and there is a window hole 4 on the target board 3 for placing the self-heating material package 5. In fact, we can even further simplify it to only have the target 1. Place the target 1 at a height suitable for aiming practice. When conducting aiming practice, take out the self-heating material package 5 from the sealed bag and paste it on the back of the target 1.

[0036] The target 1 is made of a thin plate of a material that is a good conductor of heat. It is preferably made of a material with high thermal conductivity and relatively low price. Generally, aluminum plates, copper plates, or iron plates can be selected. Preferably, an aluminum plate with high thermal conductivity and low price is used. Its thickness should generally be greater than or equal to 0.1 mm and less than or equal to 2 mm. For daily training use, considering the comprehensive cost and durability, it is recommended that the ideal thickness can be controlled between 0.3 mm and 1 mm.

[0037] Furthermore, in order to make multiple targets used simultaneously on the training ground have unity, integrity, standardization, and standardization, we need to regulate the pasting position of the self-heating material package 5 through the target board 3 and the window hole 4 on the target board 3 for placing the self-heating material package 5 to unify multiple targets and ensure that all training targets on the training ground are consistent. We know that the self-heating material package 5 is affected by factors such as material ratio and the amount of filling. Its heating duration is usually 4 - 12 hours and it can usually only be used once. Therefore, the training target adopting this technical solution can easily replace the self-heating material package 5 to meet the needs of the military for organizing long-term and multiple shooting trainings at different training stages.

[0038] Contrast Figure 1It can also be seen that on the back of the target 1, the three self-heating material packages 5 are arranged in a triangle configuration at the top, bottom left, and bottom right. The target plate 3 also has three window holes 4 corresponding to the size, quantity, and position of the heating material packages 5. In this way, the placement of the self-heating material packages 5 can be standardized and unified through the target plate 3 and the window holes 4 on the target plate 3, so as to unify the multiple training targets on the training ground, ensure the consistency of all training targets, and ensure the consistency of the aiming conditions of all soldiers. It is important to note that the number and position of the self-heating material packages 5 are determined by the size, shape, and heat conduction efficiency of the target 1, and take into account the uniformity of the heat conduction of the entire target 1, the rationality and aesthetics of the layout, and taking into account the aiming conditions during shooting training. It is recommended to give priority to the symmetry of the layout to facilitate more accurate aiming by soldiers.

[0039] The target plate 3 in this application is made of a poor thermal conductor material. There is no specific requirement for its thickness, which can be flexibly selected according to training needs. The generally recommended thickness can be between 5 mm and 10 mm. Regarding the material of the target plate 3, this application proposes two different technical routes:

[0040] The first is a target used only for shooting and aiming practice, not for live-fire shooting. The target plate 3 has no specific material requirements, but needs to have a certain hardness to meet long-term and multiple uses. It can be made of rubber plate, PVC plate, wood plate, plywood, composite material plate, compressed plate, etc. From the perspective of durability, high strength, and resistance to deformation, it is recommended to use multi-layer plywood.

[0041] The second is a target mainly used for live-fire shooting. Due to the need for live-fire shooting, the target plate 3 needs to have a high bullet-bearing capacity, so it needs to have a certain hardness and a material that can deform little after the bullet penetrates, leaving a small bullet hole, such as EVA foam board, rubber board, etc.

[0042] It is important to note that the three windows 4 on the target plate 3 correspond to the size, quantity, and location of the planned self-heating material packs 5. The size of the windows 4 depends on the size of the self-heating material packs 5 used. The size of the windows 4 should be larger than or equal to the size of the self-heating material packs 5 so that the self-heating material packs 5 can be easily attached to the back of the target 1 through the windows 4 and can also be easily replaced with new self-heating material packs 5.

[0043] Compare with Figure 2 , Figure 2 This is the exploded view of the second embodiment of the present application. Figure 2It can be seen that the center 10-ring of the target 1 in the shape of a chest ring target is cut into a circular hole, forming a hole-type aiming point 2 in the 10-ring area. Obviously, since the target 1 is a good conductor of heat, the three self-heating material packages 5 arranged in a triangular shape will conduct heat to the entire target 1 in the shape of a chest ring target. However, since the aiming point 2 in the 10-ring area is a hole area without a good conductor of heat material, the heat cannot reach this 10-ring area, thus forming a low-temperature area at the center of the 10-ring in the infrared thermal imaging sight. This 10-ring low-temperature area will also be clearly displayed in the infrared thermal imaging sight, enabling soldiers to conduct precise aiming practice on the 10-ring.

[0044] Refer to the attached Figure 3 , Figure 3 is the perspective view from the side and rear of the second embodiment of the present application. This attached drawing presents the perspective view from the side and rear angle after the target of the second embodiment is assembled. Through this figure, we can further clearly understand the state and mutual positional relationship when the target 1, the aiming point 2, the target board 3, the window hole 4, and the self-heating material package 5 in the present application are assembled together.

[0045] Obviously, since this technical solution does not require pasting the self-heating material package 5 on the target 1 in advance, and even does not need to provide the self-heating material package 5, but it is recommended that users directly purchase it from the market. On the one hand, the purchase quantity can be determined by the training plan and the number of participants. On the other hand, the self-heating material package 5 has a validity period, and over time, the heating efficiency will decrease or even fail. By allowing users to purchase it according to the training schedule, the quality of the self-heating material package 5 can be better ensured. Therefore, in this technical solution, there is no need to seal the combination of the target and the target board either.

[0046] Furthermore, refer to the attached Figure 4 , Figure 4 is the exploded view of the third embodiment of the present application. In this embodiment, on the basis of the second embodiment, a target paper 6 is further added. The target paper 6 is placed on the combination of the target 1 and the target board 3, and the target-shaped area of the target paper 6 is aligned with the target 1. According to the resolution of the infrared thermal imaging sight and the infrared thermal imaging principle, actually, this target paper 6 cannot be recognized in the infrared thermal imaging sight. But why add the target paper 6? The main considerations are as follows:

[0047] First, expand the scope of use of the target of this application. As a target for military training, it is only used for infrared thermal imaging sights, and obviously its utilization efficiency is not high. Because most of the aiming exercises of the troops are still carried out during the day in visible light conditions, using mechanical sights or white light sights for aiming practice. After adding the target paper 6 to the target board 3 in this application, not much cost will be increased, but it can meet the aiming training of the troops in both visible light and invisible light states, greatly expanding the scope of use of the target of this application.

[0048] Second, the target paper can play a certain heat preservation role. We know that the aluminum plate is a good heat radiator, which is a disadvantage of this technical solution. Because the heat is quickly dissipated into the air, the temperature of the aluminum plate will decrease, and it is difficult to obtain a large temperature difference between the aluminum plate and the ambient temperature. Therefore, the target paper 6 can play a certain heat preservation role to a certain extent. Based on this point, we can also choose target paper with a larger thickness and better heat preservation effect to reduce the heat transfer to the air.

[0049] Third, increase the integrity and aesthetics of the target. The target paper can make the whole target more complete, and the target paper can also protect the aluminum plate, making the whole target surface cleaner and more beautiful.

[0050] In the first, second, and third of the above embodiments, the self-heating material pack 5 is pasted on the back of the target 1 through the adhesive layer on the self-heating material pack 5. Since this infrared thermal imaging target is designed as a reusable target with a self-heating material pack 5 that can be replaced multiple times, if the self-heating material pack 5 is directly pasted on the target 1 through the adhesive layer, it will be time-consuming and laborious to replace the self-heating material pack 5, and it is not fast enough. This is because: on the one hand, the adhesive layer has strong adhesion and is difficult to remove; on the other hand, the adhesive layer will also stick to the self-heating material powder, making it difficult to remove completely. For this reason, this application further proposes a technical solution for placing and fixing the self-heating material pack 5:

[0051] The technical solution for placing and fixing the self-heating material pack 5 is proposed respectively according to two different technical routes of the target board 3:

[0052] First, a target for only shooting aiming practice without live ammunition shooting. Since this technical route does not need to consider the shooting of bullets, it has greater flexibility.

[0053] Second, a target mainly used for live ammunition shooting. This technical route needs to consider the shooting of bullets, so the structure for placing and fixing the self-heating material pack 5 needs to consider being able to withstand repeated shooting of bullets.

[0054] First, the fixing scheme of the self-heating material pack 5 for a target that only conducts shooting aiming practice without live ammunition shooting is proposed below:

[0055] Compare with the appendix Figure 5 ,Figure 5 is the rear side perspective view of the fourth embodiment of the present application. Referring to the attached Figure 5 As can be seen, in this embodiment, there are 4 elastic pieces 7 around each window hole. One end of each elastic piece 7 is installed on the target board 3 and can rotate around the installation axis, so that the other end is either inside the window hole or on the target board. After the self-heating material package 5 is placed in the window hole, rotate the elastic plate 7 so that the other end is inside the window hole, thereby tightly pressing the self-heating material package 5 against the back of the target 1.

[0056] Referring to the attached Figure 6 , Figure 6 is the rear side perspective view of the fifth embodiment of the present application. Referring to Figure 6 As can be seen, in this embodiment, each window hole is equipped with a spring clip 8. One end of the spring clip 8 is installed on the target board 3, and the other end has a pressing plate 9, and the pressing plate 9 is located inside the window hole. The other end of the spring clip 8 and the pressing plate 9 can be lifted upward to place the self-heating material package 5. After the self-heating material package 5 is placed in the window hole, release the other end of the spring clip 8, and the pressing plate 9 presses the self-heating material package 5 tightly against the back of the target 1 under the action of the spring.

[0057] In the fourth and fifth embodiments above, the self-heating material package 5 does not need to be pasted to the target through an adhesive layer, but is tightly pressed against the back of the target 1 by the elastic piece 7 or the spring clip 8, thus making it much simpler and quicker to replace the self-heating material package 5.

[0058] However, obviously, since neither the elastic piece 5 nor the spring clip 8 can withstand the shooting of bullets, it can only be used for daily aiming practice and cannot be used for live ammunition shooting.

[0059] Next, in combination with the technical route of the live ammunition shooting target, the structure for fixing the self-heating material package 5 that can withstand bullet shooting will be designed:

[0060] Referring to the attached Figure 7 , Figure 7 is the rear side perspective view of the sixth embodiment of the present application. Referring to the attached Figure 7 As can be seen, there is a hook and loop fastener A surface 10 around the window hole. The self-heating material package 5 placed in the window hole is attached to the back of the target 1 through the combination of the hook and loop fastener B surface 11 and the hook and loop fastener A surface 10. Obviously, since the hook and loop fastener (also known as "Velcro", "adhesive tape", "mother and son buckle", etc.) has good openability and closability, it makes it very convenient to replace the self-heating material package 5; since the hook and loop fastener is a woven fabric, it has good air permeability and can ensure the oxygen supply of the self-heating material package 5; at the same time, this woven fabric can also withstand the penetration of bullets without being easily damaged structurally, so it is an ideal material that can be applied to this infrared thermal imaging target.

[0061] Referring to the attached Figure 8 ,Figure 8 It is the second side rear perspective view of the sixth embodiment of the present application. Referring to the attached Figure 8 As can be seen, inside the window hole of this drawing, a padding cotton 12 is further added between the self-heating material pack 5 and the B side 11 of the hook and loop fastener. The padding cotton 12 can be a kind of sponge or a fluffy foam body. The main purpose of adding the padding cotton 12 is that since the target board 3 used during shooting mostly adopts an EVA foam board, usually with a thickness of about 10 millimeters or even thicker, while the thickness of the existing self-heating material pack 5 is usually only about 3 to 5 millimeters. Therefore, the purpose of the padding cotton 12 is to fill the gap between the self-heating material pack 5 and the B side 11 of the hook and loop fastener to ensure that the self-heating material pack 5 can closely adhere to the back of the target 1.
