[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] Compare with Figure 1 , 2 , Figure 1 is an exploded view of one of the embodiments of the present application, Figure 2 1 is a front perspective view of one embodiment of the present application. Figure 1It can be seen that the reusable self-heating infrared thermal imaging precision target is composed of a target 1, a self-heating material package 2, a target plate 3, and a back plate 4. The target 1 is made of a good thermal conductor material. One of the embodiments uses a target 1 in the shape of a chest ring target, in which the central 10-ring area is cut into a circular hole to form a 10-ring area hollow aiming point 5; the target 1 is pasted on the front of the target plate 3, and the target plate 3 is made of a poor thermal conductor material; on the back of the target 1, there are 3 self-heating material packages 2 in an isosceles triangle at the top, bottom left, and bottom right. The target plate 3 is configured to form a bilaterally symmetrical shape, which is convenient for shooting and aiming. There are window holes 6 on the target plate 3. The number of window holes 6 is the same as the number of self-heating material bags 2, which is also 3. They are arranged in an isosceles triangle at the top, bottom left, and bottom right. Their sizes and positions correspond to the sizes and positions of the self-heating material bags 2, so that the three self-heating material bags 2 are respectively located in their corresponding window holes 6. A back plate 4 is attached to the back of the target plate 3. The back plate 4 is made of a poor thermal conductor material. There are air holes 7 on the back plate 4. The air holes 7 correspond to the positions of the self-heating material bags 2. Figure 2 The relative position correspondence between the self-heating material package 2, the window hole 6 and the air vent 7 can be clearly seen in the front perspective view.

[0024] Compare with Figure 3 , 4 , Figure 3 This is a rear view stereogram state 1 of one embodiment of the present application, Figure 4 This is the rear view stereoscopic state 2 of one of the embodiments of the present application. Figure 3 The rear view stereogram state 1 is the use state, Figure 4 The rear view stereogram state 2 shows the state when the opening 8 on the back plate 4 is opened. Figure 3 , Figure 4 It can be seen that since the back plate 4 is usually made of EVA foam, which is soft and can be bent, we set a lifting opening 8 that can be opened or closed on the back plate 4, and the position of the lifting opening 8 corresponds to the position of the window hole 6. There is a vent 7 on the lifting opening 8, and the position of the vent 7 corresponds to the position of the self-heating material bag 2. In order to ensure that the self-heating material bag 2 has sufficient oxygen supply, further comparison Figure 2 , Figure 3 It can be seen that each of the air holes 7 corresponding to the self-heating material package 2 has 5 small holes, which are located at the four corners and the geometric center of the self-heating material package 2; Figure 4It can be seen that when the opening 8 is opened, the internal window hole 6 and the self-heating material package 2 placed in the window hole 6 are exposed. In this way, we can place or replace the self-heating material package 2 at any time. When in use, the opening 8 is opened and the self-heating material package 2 is placed in the window hole 6. When the use is finished or the self-heating material package 2 fails, the self-heating material package 2 in the window hole 6 is cleaned and a new self-heating material package 2 is put back to achieve reuse.

[0025] Further reference Figure 2 , Figure 4 In order to ensure that the opening 8 can be opened more conveniently and can ensure flatness and stability when closed, the following two aspects of design are mainly adopted:

[0026] First, the opening size of the opening 8 is larger than the size of the window hole 6. Since there is adhesive between the target plate 3 and the back plate 4, the surroundings of the opening 8 can be pasted on the surroundings of the window hole 6.

[0027] Second, the opening 8 is cut with an inclined cut rather than a 90-degree right-angle cut. Figure 2 It can be seen that the opening 8 is displayed as two non-overlapping dotted lines, indicating that the inner and outer sides of the cut are inconsistent in size, the inner side is slightly larger, and the outer side is slightly smaller; since the back panel 4 is usually EVA foam, it has good compression deformation characteristics, and therefore, it can be easily opened under the action of external force, and can also be easily closed flatly and maintain stability under the action of external force.

[0028] Furthermore, the comparison Figure 1 It can also be seen that there can be a target paper 9 in front of the target 1, which is pasted on the combination of the target 1 and the target plate 3, and the target-shaped area of ​​the target paper 9 is aligned with the target 1. According to the resolution of the infrared thermal imaging sight and the principle of infrared thermal imaging, in fact, the target paper 9 cannot be identified in the infrared thermal imaging sight. The reason for adding the target paper 9 is mainly based on the following considerations:

[0029] First, the scope of use of the target of the present application is expanded. As a target used for military training, it is only used for infrared thermal imaging sights, which is obviously not efficient, because most of the aiming exercises of the troops are still carried out in the daytime under visible light, using mechanical sights or white light sights for aiming exercises. In the present application, adding target paper 9 to the combination of target 1 and target plate 3 does not increase the cost too much, but can meet the troops' aiming training under visible light, greatly expanding the scope of use of the target of the present application.

[0030] Second, the target paper can play a certain role in heat preservation. As we know, the aluminum plate is a good radiator, which is a disadvantage of this technical solution, because the heat is quickly dissipated into the air, which will cause the temperature of the aluminum plate to drop, and it is difficult to obtain a large temperature difference between the aluminum plate and the ambient temperature. Therefore, the target paper 9 can play a certain role in heat preservation.

[0031] The third is to increase the integrity and aesthetics of the target. The target paper 9 can make the entire target more complete, and the target paper 9 can also protect the target 1 made of aluminum plate, making the entire target surface cleaner and more beautiful.

[0032] Obviously, the reusable self-heating infrared thermal imaging precision target using the above technical solution does not need to be placed in the self-heating material bag 2 during assembly, but can be placed in the self-heating material bag 2 during use, so that the entire target does not need to be sealed, and multiple reuses can be achieved by replacing the self-heating material bag 2. When the self-heating material in the self-heating material bag 2 is completely oxidized and no longer releases heat, the opening 8 is opened, the self-heating material bag 2 that is no longer emitting heat is removed, and a new self-heating material bag 2 is replaced, and it can be used again.

[0033] The target 1 of the present application is made of a good thermal conductor material. Considering the thermal conductivity and material prices of various good thermal conductor materials, we can preferably choose an aluminum plate to make the target 1.

[0034] Similarly, the target plate 3 and the back plate 4 are made of materials that are poor conductors of heat. Considering the performance and price of each material, we should preferably choose EVA material, rubber material, or PVC material, etc. When the bullet passes through these materials, the holes formed by the back plate 4 will shrink to a certain extent, thereby retaining the self-heating material in the form of a mixed powder in the window hole 6 to continue to release heat, thereby extending the use time.

[0035] The reusable self-heating infrared thermal imaging precision target described in the present application has the remarkable characteristics and advantages of requiring no external power supply, no technical support, no maintenance, being easy and quick to use, and having low cost. It effectively solves the problem of the lack of shooting training targets for infrared thermal imaging sights and fills the gap in military and police training.
