Description

Technical Field

[0001] This invention belongs to the field of target drone technology, specifically a multi-functional shooting position that can move automatically. Background Technology

[0002] In the field of shooting training and tactical drills, mobile target drones are core equipment for improving shooters' combat reaction capabilities, and their target structure directly determines the realism of the training scenario. Currently, the industry widely uses flat, sheet-like target plates as humanoid simulation carriers. These target plates are typically connected to track-mounted target drones or mobile target vehicles via fixed frames to achieve actions such as linear movement along a preset trajectory and turning. From a structural design perspective, flat target plates have advantages such as lightweight design, low manufacturing cost, and convenient target replacement, and are therefore widely used in various training grounds.

[0003] However, in practical applications, the planar target plate has a key technical flaw when following a target drone or vehicle as it turns, failing to simulate the three-dimensional turning posture of a real human body. This leads to a significant deviation between training scenarios and actual combat needs, specifically in the following aspects: First, when a real human body turns, the upper body rotates, forming a three-dimensional posture of sideways turning, with the effective hit area dynamically changing with the turning action. The planar target plate, however, can only achieve overall translation and rotation within a two-dimensional plane, always appearing as a flat silhouette, lacking independent posture adjustment of the upper body and unable to reproduce the sideways characteristics of a human body turning. Second, the three-dimensional structure of a real human body distinguishes between the effective hit area and the spatial blind zone. The planar target plate can only make hit judgments based on a planar area, failing to simulate the spatial hit differences of a three-dimensional human body, resulting in distorted training hit data and making it difficult to accurately assess the shooter's combat capabilities.

[0004] To overcome the aforementioned shortcomings of flat, sheet-like target plates, an improved solution has emerged in the industry: directly mounting upper body models onto target vehicles, attempting to recreate the posture characteristics of the human body during turning using a three-dimensional model. However, this approach still faces a series of new application problems: these models are mostly made of flexible molding materials such as plastic or silicone, resulting in significantly higher procurement costs and molding process complexity compared to traditional sheet-like target plates, leading to persistently high manufacturing costs; simultaneously, their resistance to impact during shooting is poor, making them easily penetrated and torn by projectiles during live-fire training, requiring frequent replacement and significantly increasing material costs and logistical pressure. Furthermore, the debris generated after structural damage is difficult to recycle, easily causing environmental pollution and compromising the continuity and stability of training. Summary of the Invention

[0039] The beneficial effects of this invention are as follows:

[0040] 1. The present invention discloses a self-propelled multi-functional shooting position that uses fine sand to fill rubber plates to form a three-dimensional structure resembling the upper body of a human. When the intelligent target vehicle drives the training mechanism to turn, it can naturally simulate the three-dimensional posture changes of the upper body, such as turning and side-turning, when a real human body turns. This allows the effective hit area to be dynamically adjusted with the turning action, completely solving the core defect of traditional flat target plates that can only achieve two-dimensional translation and rotation and cannot reproduce the side-turning characteristics of a human body. At the same time, compared with existing three-dimensional human models made of plastic and silicone, the rubber plates used are cheaper to purchase and can be replaced without damage. The holes in the inner and outer rubber plates can be sealed by rotating the outer rubber plate to misalign them, and they can be reused. Meanwhile, the leaked fine sand can be recovered through the hopper and refilled by the auger, realizing the recycling of fine sand and greatly reducing the cost of consumable replacement and the pressure of logistical supply. In addition, the combination structure of rubber plate and fine sand has better resistance to shooting impact and does not produce polluting debris that is difficult to recover. It is suitable for long-term live-fire training needs and ensures the continuity and stability of training.

[0041] 2. The self-propelled multi-functional shooting position described in this invention utilizes fine sand particles with high density to create continuous resistance against bullets, rapidly dissipating their kinetic energy. The bullets ultimately remain within the fine sand, preventing them from penetrating the training mechanism and posing a safety risk to surrounding personnel or animals. Furthermore, compared to the problem of bullet fragmentation and scattering during shooting with traditional steel targets, the fine sand effectively blocks the scattering fragments, eliminating the risk of accidental injury from shrapnel. Simultaneously, the steel plate structure of the first cylinder provides final protection against high-energy bullets, further enhancing training safety.

[0042] 3. The self-propelled multi-functional shooting position of the present invention, by adding a second cylinder of the same material to the inner ring of the first cylinder, forms a double steel plate protective structure, which can provide secondary obstruction for bullets penetrating the first cylinder, preventing the bullet from directly impacting the internal guide tube and core transmission components such as the auger. At the same time, when the first cylinder develops holes or cracks due to long-term shooting, the colored aqueous solution will permeate into the fine sand and flow out from the holes in the rubber plate, which can quickly remind the training personnel that the first cylinder is damaged and needs to be replaced in time. In addition, after the aqueous solution soaks into the fine sand, the fine sand particles are bound together to form a dense agglomerate by means of capillary force and surface tension. When the bullet penetrates, it has to overcome the resistance of the particle binding structure, further consuming the bullet's kinetic energy, greatly reducing the impact force of the bullet on the first cylinder and reducing the probability of the first cylinder breaking.

[0056] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0057] like Figures 1 to 11 As shown, the present invention provides an automatically moving multi-functional shooting position, which is an embodiment of the present invention; it includes an intelligent target vehicle 1; a target pole 11 is installed on the intelligent target vehicle 1; a training mechanism is provided above the target pole 11; the training mechanism includes a first cylinder 2, and the cross-section of the first cylinder 2 is oblong, and it is made of steel plate material;

[0058] The first cylinder 2 is equipped with sealing plates 21 at both the top and bottom, and the sealing plates 21 are also oblong; the first cylinder 2 is provided with a guide tube 22 inside, and there is a gap between the top of the guide tube 22 and the top sealing plate 21, and the bottom of the guide tube 22 passes through the bottom sealing plate 21 and is fixed on the bottom sealing plate 21.

[0059] The guide cylinder 22 has an auger 23 rotating inside; the lower surface of the sealing plate 21 at the bottom has two support rods 24 fixed; the top of the target rod 11 is equipped with a hopper 25, and the support rods 24 are fixed inside the hopper 25.

[0060] The opening at the top of the hopper 25 extends outward; the guide cylinder 22 and the auger 23 both extend into the hopper 25; a first motor 26 is installed at the bottom of the hopper 25, and the first motor 26 is used to drive the auger 23 to rotate.

[0061] A guide plate 27 slides on the outer ring surface of the top of the guide cylinder 22, and the guide plate 27 is oblong, and the outer ring surface of the guide plate 27 is in contact with the inner ring surface of the first cylinder 2.

[0062] The first cylinder 2 has uniformly arranged notches 28 on the inner ring of the first cylinder 2 near the guide plate 27; a ring plate 29 is provided below the guide plate 27, and the ring plate 29 is fixed to the inner ring of the first cylinder 2 and is used to support the guide plate 27.

[0063] Limiting rings 3 are installed on the outer rings of the sealing plates 21 located at the top and bottom, and the upper and lower limiting rings 3 are mirror images of each other; the limiting rings 3 are oblong.

[0064] An annular groove 31 is provided on the outer surface of each of the two limiting rings 3; two rubber plates 32 are provided between the two limiting rings 3, and the rubber plates 32 are made of soft rubber material;

[0065] Both rubber plates 32 are fixed with rubber rings 33 at the top and bottom. The two rubber rings 33 on the inner rubber plate 32 are respectively fitted into the annular grooves 31 of the two limiting rings 3 that are close to each other, while the two rubber rings 33 on the outer rubber plate 32 are respectively fitted into the annular grooves 31 of the two limiting rings 3 that are far apart from each other.

[0066] In practice, before use, fine sand is first poured into the hopper 25. Then, the first motor 26 is controlled to rotate. The rotating first motor 26 drives the auger 23 to rotate counterclockwise when viewed from above. The rotating auger 23 pushes the fine sand gradually upward along the guide cylinder 22. When the fine sand moves to the top of the guide cylinder 22, because there is a certain gap between the top of the guide cylinder 22 and the sealing plate 21 above, the fine sand that has moved to the top of the guide cylinder 22 will fall onto the guide plate 27. Subsequently, as the amount of fine sand gradually increases, the fine sand will move along the guide plate 27 and gradually pass through the notch 28 opened on the first cylinder 2, and gradually enter the space between the first cylinder 2 and the rubber plate 32. The sand eventually falls onto the top of the lower limiting ring 3. As more fine sand enters the space between the first cylinder 2 and the rubber plate 32, it gradually fills the gap. Since the top and bottom of the rubber plate 32 are fitted into the annular groove 31 by the rubber ring 33, the rubber plate 32 can be fixed and the sand can be restricted from falling in. When the sand fills the space between the rubber plate 32 and the first cylinder 2, the auger 23 stops pushing the sand. At this time, the shape of the rubber plate 32 filled with sand will resemble the shape of the human upper body, thus simulating the human upper body. Shooting training can then be conducted.

[0067] Specifically, during shooting training, the intelligent target vehicle 1 moves the training mechanism, causing it to move in a straight line, turn, and change direction along a preset trajectory. Shooting training can then commence, and trainees can fire at the moving training mechanism. When a bullet hits the training mechanism, it first penetrates two rubber plates 32 and then enters the fine sand. Due to the small particle size and high density of the fine sand, it creates continuous resistance to the bullet, accelerating the dissipation of its kinetic energy. Different firearms emit bullets with varying kinetic energy; bullets with high kinetic energy will penetrate the sand and impact the first cylinder 2. Since the first cylinder 2 is made of steel, it can prevent the bullet from moving further. When the bullet passes through the rubber plate 32, it will form a hole in the rubber plate 32, so some of the fine sand inside the rubber plate 32 will leak out and fall into the hopper 25. The leaked fine sand can also highlight the location of the bullet hit. At the same time, since the bullet will remain in the fine sand, it can prevent the bullet from penetrating the training mechanism and continuing to fly. If there are other people or animals nearby, it will cause safety hazards. In the current training using steel target plates, when the bullet hits the steel target plate, it will shatter and scatter. However, in this training mechanism, since the bullet passes through the fine sand first, when the bullet is impacted and shatters and scatters, the fine sand can block the scattering fragments and prevent the scattering fragments from hitting people or other animals.

[0068] More specifically, during training, the shape of the sand-filled rubber plate 32 resembles the shape of the human upper body, thus simulating the three-dimensional posture changes of the human body when moving or turning, and reproducing the sideways posture of the human body when turning. After training, the outer rubber plate 32 can be rotated, causing the rubber plate 32 to drive the rubber ring 33 to rotate within the annular groove 31. When the outer rubber plate 32 rotates, the holes on the inner and outer rubber plates 32 will be misaligned, thereby sealing the holes. Alternatively, patches can be pasted to seal the holes, and the model can then be reused. Moreover, the price of the rubber plate 32 itself is lower than that of the finished model, thus reducing costs. Additionally, nylon cloth or other materials can be pasted onto the upper and lower rubber rings 33 to replace the rubber plate 32, with the specific materials chosen based on actual costs.

[0069] Furthermore, by filling the rubber plate 32 with fine sand to form a three-dimensional structure resembling the upper body of a human, when the intelligent target vehicle 1 drives the training mechanism to turn, it can naturally simulate the three-dimensional posture changes of the upper body, such as turning and side-to-side turning, when a real human body turns. This allows the effective hit area to be dynamically adjusted with the turning action, completely solving the core defect of traditional flat target plates that can only achieve two-dimensional translation and rotation and cannot reproduce the side-to-side characteristics of a human body. At the same time, compared with the existing three-dimensional human body models made of plastic and silicone, the rubber plate 32 used has a lower procurement cost and can be replaced without damage. By rotating the outer rubber plate 32 to misalign the holes of the inner and outer rubber plates 32, it can be sealed and reused. Meanwhile, the leaked fine sand can be recovered through the hopper 25 and refilled by the auger 23, realizing the recycling of fine sand and greatly reducing the cost of consumable replacement and the pressure of logistical supply. In addition, the combined structure of the rubber plate 32 and fine sand has better resistance to shooting impact and does not produce polluting debris that is difficult to recover. It is suitable for long-term live-fire training needs and ensures the continuity and stability of training.

[0070] Meanwhile, due to the small size and high density of fine sand particles, it can create continuous resistance to the bullet, quickly dissipating its kinetic energy. The bullet will eventually remain in the fine sand, avoiding the risk of penetrating the training facility and causing safety hazards to surrounding personnel or animals. On the other hand, compared with the problem of bullet fragmentation and scattering when shooting at traditional steel targets, fine sand can effectively block the scattering shrapnel, eliminating the risk of accidental injury from shrapnel. At the same time, the steel plate structure of the first cylinder 2 can provide the final block for high-energy bullets, further improving training safety.

[0071] As one embodiment of the present invention; a fixing plate 4 is installed on the outer ring of the guide tube 22, and a gap is left between the fixing plate 4 and the guide plate 27;

[0072] The top of the fixed plate 4 is fixed with a first slider 41, and the cross-section of the first slider 41 is an inverted trapezoid; a movable plate 42 is provided above the fixed plate 4, and the movable plate 42 is staggered with the fixed plate 4.

[0073] The bottom of the movable plate 42 is provided with a first groove 43, and the first slider 41 slides in the first groove 43.

[0074] The bottom of both the fixed plate 4 and the movable plate 42 are rotatably connected to a first rotating roller 44; the first rotating roller 44 located below the movable plate 42 is driven by a second motor 45, and the second motor 45 is installed inside the movable plate 42.

[0075] A sliding shaft 46 is fixed above the movable plate 42; a limiting groove 47 is formed on the lower surface of the top sealing plate 21 above the sliding shaft 46, and the limiting groove 47 is oblong and parallel to the outer ring of the guide plate 27; the sliding shaft 46 slides in the limiting groove 47.

[0076] A horizontal plate 48 is fixed to the side of the fixed plate 4; a long groove 49 is provided on the horizontal plate 48; a second rotating roller 5 is provided below the horizontal plate 48; a guide rod 51 rotates on the second rotating roller 5, and the guide rod 51 extends through the long groove 49 to the horizontal plate 48.

[0077] The guide rod 51 extends to one side above the horizontal plate 48 and is fixed with a moving block 52; the end of the horizontal plate 48 is fixed with a stop block 53, and a spring connects the stop block 53 and the moving block 52.

[0078] A conveyor belt 54 rotates on two first rollers 44 and one second roller 5;

[0079] In this embodiment, push plates 55 are uniformly arranged on the outer ring surface of the conveyor belt 54.

[0080] During implementation, when the auger 23 rotates counterclockwise, it will drive the fixed plate 4, the moving plate 42, and the conveyor belt 54 to rotate counterclockwise. Since the fixed plate 4 and the moving plate 42 are slidably connected by the first sliding groove 43 and the first slider 41, and the sliding shaft 46 on the moving plate 42 slides in the limiting groove 47 at the bottom of the top sealing plate 21, when the moving plate 42 rotates, it will drive the sliding shaft 46 to move along the limiting groove 47. Since the limiting groove 47 is parallel to the outer ring of the guide plate 27, when the fixed plate 4 and the moving plate 42 rotate, under the limitation of the sliding shaft 46 and the limiting groove 47, it will drive the first sliding groove 43 on the moving plate 42 to move along the first slider 41 on the fixed plate 4. During the sliding process of the moving plate 42, the fixed plate 4 will rotate along the outer ring contour of the guide plate 27. At the same time, in order to adapt to the outer ring contour of the guide plate 27, the moving plate 42 will slide along the fixed plate 4, and at the same time, the conveyor belt 54 will rotate along the inner ring of the first cylinder 2.

[0081] Specifically, during the process of the moving plate 42 sliding back and forth on the fixed plate 4, if the overall length of the moving plate 42 and the fixed plate 4 gradually increases, the conveyor belt 54 will also move along with the moving plate 42. During the movement of the conveyor belt 54, the conveyor belt 54 will pull the second roller 5 towards the side of the fixed plate 4. The guide rod 51 above the second roller 5 will slide in the long groove 49 and drive the moving block 52 towards the side of the fixed plate 4. At the same time, the spring between the moving block 52 and the stop block 53 will be gradually stretched. If the overall length of the moving plate 42 and the fixed plate 4 gradually decreases, the moving block 52 will be pulled towards the side of the stop block 53 under the action of the spring. At the same time, the moving block 52 will pull the conveyor belt 54 through the guide rod 51 and the second roller 5, thereby ensuring that the conveyor belt 54 is always in a taut state.

[0082] More specifically, when the conveyor belt 54 rotates counterclockwise following the auger 23, it pushes the fine sand falling on the guide plate 27 to rotate in a circular motion. At the same time, it controls the second motor 45 to drive one of the first rollers 44 to rotate. The rotating first roller 44 will drive the conveyor belt 54 to rotate clockwise. Therefore, as the conveyor belt 54 revolves with the auger 23, it will also rotate on its own axis. This will push the fine sand into the space between the first cylinder 2 and the rubber plate 32 as it rotates on the guide plate 27, thus allowing the fine sand to fall more evenly between the first cylinder 2 and the rubber plate 32.

[0083] As an embodiment of the present invention; both of the limiting rings 3 have circular grooves inside;

[0084] Gears 34 rotate within each of the circular grooves; the inner surfaces of the rubber rings 33 at the top and bottom of the outer ring rubber plate 32 are provided with toothed grooves, which mesh with the gears 34.

[0085] The gear 34 is driven by a third motor 35, and the third motor 35 is mounted on the limiting ring 3;

[0086] In this embodiment, the outer ring of the limiting ring 3 is fixed with uniformly arranged second sliders 36, and the cross-section of the second sliders 36 is an inverted trapezoid.

[0087] The outer ring of the limiting ring 3 is slidably provided with a baffle 37; the inner ring of the baffle 37 is provided with a second sliding groove 38, and the second slider 36 slides in the second sliding groove 38.

[0088] The outer ring of the baffle 37 is fitted with a locking bolt; the first slider 41 has a threaded hole, and the locking bolt engages in the threaded hole.

[0089] In this embodiment, the two limiting rings 3 are provided with evenly arranged threaded grooves on opposite sides;

[0090] The two sealing plates 21 are also provided with evenly arranged threaded grooves on opposite sides; the two limiting rings 3 are provided with multiple connecting plates 39 on opposite sides, and the connecting plates 39 extend to the surface of the sealing plates 21.

[0091] The connecting plate 39 has two through holes, and the two through holes coincide with the threaded grooves on the limiting ring 3 and the sealing plate 21, respectively; the connecting plate 39 has fixing bolts in the through holes, and the two fixing bolts engage with the threaded grooves on the limiting plate and the sealing plate 21, respectively.

[0092] During implementation, since the gear 34 in the circular groove meshes with the toothed grooves on the upper and lower rubber rings 33 of the outer rubber plate 32, when the outer rubber plate 32 needs to be rotated, the third motor 35 is controlled to rotate. The rotating third motor 35 will drive the toothed rubber rings 33 to rotate through the gear 34, thereby driving the outer rubber plate 32 to rotate, so that the hole is misaligned and sealed.

[0093] Specifically, after the rubber ring 33 is fitted into the annular groove 31, the baffle 37 is pushed to move, causing the second sliding groove 38 on the baffle 37 to move along the second slider 36. During the movement of the baffle 37, the rubber ring 33 gradually moves into the inside of the baffle 37, thereby fixing and limiting the rubber ring 33 and the rubber plate 32. Then, the locking bolt is rotated to align the locking bolt with the threaded hole in the second slider 36, and the locking bolt is turned into the threaded hole to fix the baffle 37. At the same time, the baffle 37 can be used to protect the limiting ring 3, and the baffle 37 is made of steel plate material.

[0094] More specifically, when the rubber plate 32 needs to be replaced, first turn the locking screw out of the second slider 36 and move the stop cylinder 37 away from the limiting ring 3. Then, release the fine sand inside the rubber plate 32. Then, turn the fixing bolt that engages with the threaded groove on the limiting ring 3, so that the limiting ring 3 is no longer fixed. Then, turn the connecting plate 39 to the side of the sealing plate 21. Then, the limiting rings 3 on the upper and lower sides can be removed. After the limiting rings 3 are removed, the rubber ring 33 is removed from the annular groove 31, so that the rubber plate 32 is removed from the limiting ring 3. Then, the new rubber plate 32 is put on the limiting ring 3, and the rubber ring 33 is put on the annular groove 31. Then, the two limiting rings 3 are put on the outer ring of the first cylinder 2, and then fixed with the connecting plate 39 and the fixing bolt.

[0095] As one embodiment of the present invention; the inner ring of the first cylinder 2 is provided with a second cylinder 6, and the second cylinder 6 is also made of steel plate material;

[0096] The second cylinder 6 is located below the guide plate 27; the bottom of the second cylinder 6 is mounted on the bottom sealing plate 21;

[0097] In this embodiment, a sealing ring 61 is provided between the first cylinder 2 and the second cylinder 6, and the sealing ring 61 is located at the bottom of the first cylinder 2 and the second cylinder 6.

[0098] The first cylinder 2 and the second cylinder 6 contain an aqueous solution containing dye;

[0099] In this embodiment, the sealing plates 21 located at the top and bottom of the first cylinder 2 are fixed to the first cylinder 2 by bolts;

[0100] The bottom of the second cylinder 6 is also fixed to the bottom sealing plate 21 by bolts; the fixing plate 4 is installed on the auger 23 by bolts.

[0101] During implementation, as the training facility is used for a long time, when the first cylinder 2 develops holes due to repeated impacts from bullets, the second cylinder 6, located inside the first cylinder 2, can again block bullets passing through it, thus preventing the bullets from impacting the internal guide tube 22 and damaging the auger 23 inside. Simultaneously, since the first and second cylinders 2 and 6 contain an aqueous solution with added dye, when the first cylinder 2 cracks, the solution will seep into the fine sand and then flow out through the holes in the rubber plate 32. This process alerts the trainees that the first cylinder 2 is damaged and needs replacement. Furthermore, when the solution seeps into the fine sand, the water on the surface of the sand particles will bind adjacent particles together through capillary action and surface tension, forming a dense sand agglomerate. When a bullet penetrates, it must not only overcome particle friction but also disrupt the agglomerate's binding structure, consuming a significant amount of kinetic energy, thereby reducing damage to the first cylinder 2.

[0102] Specifically, when the first cylinder 2 needs to be replaced, first rotate the fixing bolt that engages with the threaded groove on the sealing plate 21 and remove the bolt. Then rotate the connecting plate 39 to the side of the limiting ring 3. Then rotate the bolt connecting the first cylinder 2 and the sealing plate 21. After the bolt is removed, the upper and lower sealing plates 21 can be separated from the first cylinder 2. Then a new first cylinder 2 can be replaced and placed between the upper and lower sealing plates 21. Then it can be fixed with bolts.

[0103] More specifically, by adding a second cylinder 6 of the same material to the inner ring of the first cylinder 2, a double steel plate protective structure is formed, which can provide secondary obstruction for bullets penetrating the first cylinder 2, preventing the bullet from directly impacting the core transmission components such as the internal guide tube 22 and the auger 23. At the same time, when the first cylinder 2 develops holes or cracks due to long-term firing, the colored aqueous solution will seep into the fine sand and flow out from the holes in the rubber plate 32, which can quickly remind the training personnel that the first cylinder 2 is damaged and needs to be replaced in time. In addition, after the aqueous solution soaks into the fine sand, the fine sand particles are bound together to form a dense agglomerate by means of capillary force and surface tension. When the bullet penetrates, it needs to overcome the resistance of the particle binding structure, further consuming the bullet's kinetic energy, greatly reducing the impact force of the bullet on the first cylinder 2, and reducing the probability of the first cylinder 2 breaking.
