Background Art

[0002] It is known that many energetic materials can undergo chemical reactions or oxidation reactions and release heat when triggered. For example, when a single metal is mixed with a metal oxide and ignited, a strong redox reaction will occur. The single elements can be aluminum, magnesium, calcium, titanium, silicon, and boron - not limited to metals, and the metal oxides can be boron trioxide, silicon dioxide, chromium trioxide, manganese dioxide, iron trioxide, iron tetraoxide, copper oxide, and lead tetraoxide. Sometimes these reactions are also called "magnesium thermal method", "silicon thermal method", "calcium thermal method", "carbon thermal method", etc. according to the reducing agent in the reaction.

[0003] It is known that there is a kind of self-heating material, which is a material obtained by specially packaging by using a chemical heating agent to contact with oxygen to produce a chemical reaction and release heat. It is widely used because of its simple production, convenient carrying, low price and easy use, and is more popular in cold areas and among people working in the field. Its formula mainly includes: reduced iron powder, activated carbon, salt, water, etc. The components in the above composition are mixed evenly under vacuum or nitrogen protection according to the metered amount, and then packed and sealed for storage. Since the contact between oxygen in the heating agent and the formula material is the key to heating, the heating conditions are different due to different contacts. Under the best conditions, the heating duration can be up to 24 hours, and the maximum temperature can reach 74°C. The products made of these materials can be used for temporary heating when traveling or working and living in cold areas; they can also be used for cushions, knee pads, and building insulation materials that require insulation functions.

[0004] On November 9, 2023, the inventor of this application submitted a patent application for "An infrared thermal imaging target", application numbers 202311483505.3 and 202323019553.5. The infrared thermal imaging target provides a training equipment that combines a target made of a good thermal conductor material and a self-heating material to transfer the heat released by the chemical reaction between the self-heating material and oxygen to a target with a target shape, thereby providing a shooting training target for an infrared thermal imaging sight. Summary of the invention

[0005] The infrared thermal imaging target with application numbers 202311483505.3 and 202323019553.5 is a complete flat target plate made of a good conductor of heat. The self-heating material package at the rear will conduct heat to the entire target plate. Under the infrared thermal imaging sight, it is displayed as an overall high-temperature area with heating. The bull's eye is determined and aimed by the shooter based on the overall high-temperature area, and the bull's eye position cannot be accurately displayed. To further solve the above problems, the idea of ​​this application is to cut a hole at the bull's eye position on the target board or the position where the sniper is required to snipe accurately, so that heat cannot reach the hole area, thereby forming a low-temperature area in the infrared sight, which is the bull's eye position or the position where the sniper is required to snipe accurately. The technical solution of the present invention: a technical implementation method of an infrared thermal imaging precision target, characterized in that: a target is made of a good thermal conductor material, a hole is cut in the center of the target's bull's eye or aiming point, one or more self-heating material packages are pasted on the back side of the target, in the non-hole area, and the heat released by the chemical reaction of the self-heating material package is transferred to the entire target by using the good thermal conductor material, so that the entire target presents a thermal infrared feature with a temperature higher than the surrounding environment temperature in the infrared thermal imaging sight. At the same time, since the bull's eye or aiming point is cut as a hole, heat cannot be transferred to the hole area, and a thermal infrared feature with a temperature lower than the target temperature is presented in the infrared thermal imaging sight, thereby indicating a shooting target for a shooter using an infrared thermal imaging sight. The method is implemented according to the following steps: Step 1: Use a heat good conductor material plate with a thickness greater than or equal to 0.1 mm and less than or equal to 2 mm to make a silhouette of the shooting target to form a target, and cut one or more holes in the center of the target's bull's eye or the designated shooting position to form an aiming point; Step 2: Use a heat poor conductor material plate to make a target plate, and cut holes in the target plate to form a window hole, the size of the window hole is adapted to the size of the self-heating material package, and the number and position are consistent with the number and position of the self-heating material package to be pasted on the target, so that the self-heating material package can be pasted on the back of the target through the window hole; Step 3: Paste the target on the target plate; Step 4: Paste the self-heating material package on the back of the target through the window hole. The method also includes: after step 3, add step 3.1: paste the target paper on the target. The method also includes step 5: place the infrared thermal imaging precision target obtained by steps 1 to 4 in a sealed bag for oxygen-proof sealing and storage, and remove the sealed bag when used. The target is made of aluminum, aluminum oxide or copper. The target plate is made of EVA material, rubber material or PVC material. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] 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.

[0023] Compare with Figure 1 , 2 , Figure 1 is an exploded view of one embodiment of the present invention, Figure 2It is a side rear perspective view of one embodiment of the present invention.

[0024] from Figure 1 It can be seen that the infrared thermal imaging precision target is composed of a target 1, a target plate 3, and a self-heating material bag 5; target 1 is a front upper body silhouette of a person holding a knife, made of a thin plate of a good thermal conductor material, and its thickness should generally be greater than or equal to 0.1 mm and less than or equal to 2 mm. The recommended ideal thickness can be controlled between 0.5 mm and 1 mm. The head, heart, arm, and hand of target 1 each have a hole. These four holes are four aiming points 2 designed for the shooter to accurately hit the fatal or non-fatal parts of the person during shooting training. We mark them with head aiming point 2a, heart aiming point 2b, arm aiming point 2c, and hand aiming point 2d respectively. When shooting, the shooter can shoot at specific body parts of the person according to training needs or instructions from superiors to practice shooting skills and lay a good foundation for actual combat. Therefore, we also call this human body part target a precision shooting target. This is the material required for the first step of this application: target.

[0025] The material required for the second step of this application is: target plate. Figure 1 As can be seen from the exploded view, behind the target 1 is the target plate 3, which is made of a poor thermal conductor material. There is no specific requirement for its thickness, which can be flexibly selected according to shooting needs. The usual recommended thickness can be between 5 mm and 10 mm. There is no specific requirement for its material, which can be a rubber plate, a PVC plate, a wooden board, a composite material plate, a compressed plate, etc. It is recommended to keep the material consistent with the existing EVA target plate. There are 5 holes on the target plate 3, which we call window holes 4 in this application. The size of the window holes 4 is adapted to the size of the self-heating material package 5, and the number and position are consistent with the number and position of the self-heating material package 5 planned to be pasted on the target 1, so that the self-heating material package 5 can be pasted on the back of the target 1 through the window holes 4. It should be emphasized that the five window holes 4 here correspond to the size, quantity and position of the self-heating material packages 2 to be placed, and the size of the window holes 4 depends on the specifications of the self-heating material packages 5 we use. The size of the window holes 4 is adapted to the size of the self-heating material packages 5. Obviously, the size of the window holes 4 should be greater than or equal to the size of the self-heating material packages 5, so that the self-heating material packages 5 with a certain thickness can be completely located inside the window holes 4, and at the same time, we can stick the self-heating material packages 5 on the back of the target 1 through the window holes 4. The number and position of the window holes 4 are consistent with the number and position of the self-heating material packages 2 to be placed.

[0026] The third material required for this application is a self-heating material package 5. It is recommended that the self-heating material package 5 be a finished product that can be purchased on the market and obtained directly from a supplier.

[0027] After preparing the above three materials, you can proceed to step 3: stick the target 1 on the target plate 3; step 4: stick the self-heating material package 5 on the back of the target 1 through the window hole 4. Figure 1 It can also be seen from the exploded view that behind the target plate 3, five self-heating material packages 2 are dispersedly arranged. After the target 1 is pasted on the target plate 3, we can paste the self-heating material package 5 on the back of the target 1 through the window hole 4. Each window hole 4 corresponds to a self-heating material package 5. The relative position relationship between them is shown in the attached Figure 2 It should be emphasized that the five self-heating material packs 2 are not in specific positions as shown in the figure, nor are they in fixed numbers. Their placement and number can be flexibly determined according to factors such as the overall size of the target 1, the position and number of the aiming points 2, and the thermal conductivity coefficient of the target 1. They are pasted on the back of the target 1 to ensure that the heat generated by the self-heating material packs 5 can be better transferred to various areas of the target 1, presenting a clear thermal infrared target to the shooter.

[0028] Obviously, we can also directly stick the self-heating material package 5 on the back of the target 1 first, and then stick the target 1 on the target board 3. There is no strict order requirement for these two steps.

[0029] Through the above steps, we have obtained a basic infrared thermal imaging precision target, which realizes the use of target 1 made of a good thermal conductor material plate to transfer the heat released by the chemical reaction of the self-heating material package 5 to the entire target 1, so that the entire target 1 presents a thermal infrared feature with a temperature higher than the surrounding environment temperature in the infrared thermal imaging sight. At the same time, since the head aiming point 2a, the heart aiming point 2b, the arm aiming point 2c, and the hand aiming point 2d are cut into holes, the heat cannot be transferred to the hole area, and a thermal infrared feature with a temperature lower than the target temperature is presented in the infrared thermal imaging sight, thereby indicating the shooting target for the shooter using the infrared thermal imaging sight.

[0030] It is also important to note that the head aiming point 2a, heart aiming point 2b, arm aiming point 2c, and hand aiming point 2d, which are cut into holes, are usually circular in shape, which is more conducive to determining the aiming center. However, in high-level application shooting and actual combat shooting training, we can also cut them into more realistic shapes according to training needs, such as: cutting out eyes, nose, and mouth on the head; cutting a real heart shape on the heart; cutting a long strip of arm bone shape on the arm; in the hostage target, realistically cutting out the outline of the character's head, etc. These are all within the scope of implementation and the scope of claims included in this application. The technical implementation is simple and clear, and the industrial applicability is strong. The implementation method is obvious to relevant technical personnel, and will not be illustrated one by one in the accompanying drawings.

[0031] The infrared thermal imaging precision target of the above-mentioned embodiment is a human body part target, which is a practical precision target mostly used in sniper shooting practice, and the chest ring target is the most commonly used target in the daily training of the troops. The above design ideas are obviously also applicable to the chest ring target. Below, taking the chest ring target as an example, the technical implementation method of the infrared thermal imaging precision target is further elaborated and illustrated.

[0032] Compare with Figure 3 , 4 , Figure 3 is an exploded view of the second embodiment of the present invention, Figure 4 2 is a side and rear perspective view of the second embodiment of the present invention. Figure 3 It can be seen that the central 10 rings of the target 1 in the shape of a chest ring target are cut into a circular hole to form a hollow aiming point 2 in the 10-ring area. On the back of the target 1, three self-heating material packages 5 to be pasted are arranged in a triangle at the top, the lower left, and the lower right. The target plate 3 also has three window holes 4 corresponding to the size, quantity, and position of the heating material packages 5. At the same time, a chest ring target paper 6 is newly added to the front of the target 1. During assembly, the target 1 is first pasted on the target plate 3, and then the target paper 6 is pasted on the combination formed by the target 1 and the target plate 3, and then the self-heating material package 5 is pasted on the back of the target 1 through the window hole 4. The relative position relationship between them can be seen in the attached figure. Figure 2. After completing the above steps, an infrared thermal imaging precision target is manufactured, and then the infrared thermal imaging precision target is placed in a sealed bag and sealed for oxygen isolation. The sealed bag can be removed when in use. Obviously, the three self-heating material packages 5 arranged in a triangle will conduct heat to the target 1 in the shape of the entire chest ring target. However, since the aiming point 2 in the 10-ring area is a hollow area without a good heat conductor material, the heat cannot reach the 10-ring area, thereby forming a low-temperature area in the center of the 10-ring in the infrared sight. The 10-ring low-temperature area will also be clearly displayed in the shooter's infrared thermal imaging sight, allowing the shooter to accurately aim and shoot at the 10-ring.

[0033] Obviously, in the above embodiments, the target 1 is made of a good thermal conductor material. Considering the thermal conductivity and material price of various good thermal conductor materials, we should preferably choose aluminum, alumina or copper, which are relatively low in price, high in thermal conductivity and easy to mass produce. The target plate 3 is made of a poor thermal conductor material. Considering the performance and price of each material, we should preferably choose EVA material, rubber material, or PVC material, etc.

[0034] The infrared thermal imaging precision target manufactured by the above-mentioned infrared thermal imaging precision target technology implementation method has the following three technical advantages:

[0035] First, the aiming point is the hole area of ​​the target, which is obviously the area with the most bullet impact points, thus greatly reducing the damage of the bullet to the target;

[0036] Second, there is no self-heating material bag at the shooting aiming point, which can also greatly reduce the damage of the bullet to the self-heating material bag;

[0037] Third, the infrared thermal imaging precision target can be reused repeatedly by replacing the self-heating material package. Since the self-heating material package is a one-time use product, the infrared thermal imaging precision target made using the self-heating material package is also a one-time use product. However, since the infrared thermal imaging precision target made by the above method has a window hole 4 on the target plate 3, when the self-heating material in the self-heating material package 5 is completely oxidized and no longer releases heat, we can remove the self-heating material package 5 that is no longer heating from the window hole 4, re-paste a new self-heating material package 5, and use it again, thereby extending the use time of the infrared thermal imaging precision target and realizing the repeated use of the infrared thermal imaging precision target.

[0038] The infrared thermal imaging precision target manufactured by this method has the remarkable characteristics and advantages of no need for external power supply, no need for technical support, no need for maintenance, easy and quick use, and low cost. It effectively solves the problem of no shooting training targets for infrared thermal imaging sights and fills the gap in military and police training.
