Description

Technical Field

[0001] This invention relates to the field of shooting target technology, and more specifically, to a windmill target device and a windmill target control method. Background Technology

[0002] Currently, electric windmill targets serve as an important auxiliary tool for shooting training, aiming to simulate the uncertainty of shooting at moving targets in actual combat and increase the difficulty and realism of training. However, existing windmill targets have head that detaches directly after being hit by a bullet. While this design provides the unbalanced rotational effect resulting from the head falling off, it also has several shortcomings:

[0003] 1. Manually resetting the target head is inconvenient and dangerous; after the target head is hit, it needs to be manually reinstalled. This process is not only time-consuming and labor-intensive, but also increases the safety risks for the staff as it is within the firing range.

[0004] 2. Limited applicability of the target; Since the detachment of the target head depends on the impact force of physical shooting, the existing windmill target cannot be adapted to non-impact shooting training (such as laser shooting simulation) and low-impact shooting training (such as BB bullet shooting training), which limits its application in various shooting training scenarios.

[0005] 3. The training mode is relatively simple; once the target falls, the rotation of the target frame is entirely determined by the actual position and number of the fallen target, which lacks flexibility and adjustability and cannot meet diverse training needs.

[0006] 4. Lack of visual feedback mechanism; After the target is hit, there is no other way to provide immediate visual feedback, such as light indication, apart from the physical change of the target, which also reduces the interactivity and fun of training.

[0007] 5. Low level of automation: The entire target head reset and rotation control process of the existing windmill target relies on manual operation and simple physical mechanisms, lacking intelligent and automated control, which is inconsistent with the high automation trend of modern shooting training facilities and cannot meet the diverse shooting training needs.

[0008] Therefore, existing windmill targets suffer from problems such as inconvenience and danger in manually resetting the target head, limited applicability of the target, relatively simple training modes, lack of visual feedback mechanisms, and low degree of automation, which urgently need to be addressed. Summary of the Invention

[0009] This invention provides a windmill target device and a windmill target control method to at least solve the problems of inconvenience and danger of manual target reset, limited training modes, and low degree of automation in existing windmill targets.

[0010] To address the aforementioned problems, according to one aspect of the present invention, a windmill target device is provided, comprising: a target head assembly, a target frame assembly, a rotation drive assembly, a reset assembly, and a detection assembly; the target head assembly is disposed on the target frame assembly, the target frame assembly is disposed on the rotation drive assembly, and the rotation drive assembly is drivably connected to the target frame assembly to drive the target frame assembly and the target head assembly to rotate at a set rotation speed; wherein, the target head assembly has a ready state and a folded state, in the ready state, the target head assembly is positioned facing the firing position; when the target head assembly is physically hit, receives a corresponding electrical signal, or receives a corresponding optical signal, the target head assembly switches from the ready state to the folded state, in the folded state, the target head assembly avoids the firing position to indicate that it has been hit; the detection assembly is used to detect the state of the target head assembly, and the reset assembly is at least used to reset the target head assembly to change the target head assembly from the folded state to the ready state.

[0011] Furthermore, the target assembly includes at least two target structures, which are spaced apart circumferentially along the target frame assembly. Each target structure has a display surface; in the ready-to-fire state, the display surface faces the firing position and is parallel to or at an angle to a vertical plane; in the folded state, the display surface avoids the firing position and is parallel to or at an angle to a horizontal plane to indicate a hit. The reset assembly includes a reset motor and a reset structure, with the reset structure driven by the reset motor. After a target structure in the folded state moves to the reset assembly, the reset motor drives the reset structure to rotate, and the reset structure impacts the target structure, causing the target structure to change from the folded state to the ready-to-fire state.

[0012] Furthermore, the reset structure includes a reset impact wheel and a connecting rod frame. At least a portion of the reset impact wheel is made of an elastic material to cushion the impact. The reset impact wheel is rotatably mounted on the connecting rod frame, which is driven by a reset motor. The reset motor drives the connecting rod frame to rotate. The windmill target device also includes a base assembly. A rotation drive assembly is mounted on the upper part of the base assembly, which is mounted on the ground. The reset assembly is mounted on the base assembly and positioned to avoid firing.

[0013] Furthermore, the target head structure includes a target head component and a telescopic support rod; the target head component is rotatably mounted on the target frame assembly, one end of the telescopic support rod is connected to the side of the target head component facing away from the display surface, and the other end of the telescopic support rod is connected to the target frame assembly; the telescopic support rod is telescopically adjustable and is used to support the target head component; in the folded state, the telescopic support rod is shortened to allow the display surface to avoid the firing position; in the ready state, the telescopic support rod is extended to support the display surface facing the firing position.

[0014] Furthermore, the target frame assembly includes a carrier frame and at least two support members; the carrier frame is disposed on the rotation drive assembly; the at least two support members are circumferentially spaced along the carrier frame and extend radially along the carrier frame; the target head structure is disposed at the end of the support member away from the carrier frame; at least two target head structures are disposed in a one-to-one correspondence with at least two support members.

[0015] Furthermore, the windmill target device also includes a central controller; a rotation drive assembly is electrically connected to the central controller, which controls the target frame assembly and the target head assembly to rotate at a set speed; the detection assembly includes at least two position sensors, which are electrically connected to the central controller, and are configured one-to-one with at least two target head structures. The position sensors are mounted on the target frame assembly and are used to detect the position of the target head structure. The central controller determines the state of the corresponding target head structure based on the position information detected by the position sensors; the windmill target device also includes a light indicator, which is electrically connected to the central controller; the light indicator displays the state of the target head structure according to the change in display color and / or whether it flashes, so as to indicate whether the target head structure has been hit.

[0016] Furthermore, the windmill target device also includes a base assembly, which includes a movable base and multiple casters; the multiple casters are spaced apart below the movable base to jointly support and move the movable base; the casters have a locking function to fix the movable base; a reset assembly is disposed on the movable base and is positioned to avoid the firing position; the rotation drive assembly includes a drive motor and a support frame, the support frame is disposed on the upper part of the movable base, the target frame assembly is rotatably disposed on the support frame, and the drive motor is disposed on the support frame and is drivenly connected to the target frame assembly.

[0017] Furthermore, the target head assembly includes at least two target head structures, which are spaced apart circumferentially along the target frame assembly. Each target head structure has a display surface. In the ready state, the display surface faces the firing position and is parallel to or at an angle to a vertical plane. In the folded state, the display surface avoids the firing position and is parallel to or at an angle to a horizontal plane. The reset assembly includes at least two electrically operated telescopic rods. The target head structure is rotatably mounted on the target frame assembly. One end of each electric telescopic rod is connected to the side of the target head structure facing away from the display surface, and the other end is connected to the target frame assembly. The electric telescopic rods can automatically extend and retract. By shortening, the electric telescopic rod drives the display surface to avoid the firing position; by extending, the electric telescopic rod drives the display surface to face the firing position. At least two electric telescopic rods are correspondingly arranged with at least two target head structures. When the target head assembly receives a corresponding electrical signal or a corresponding optical signal, the electric telescopic rod corresponding to that target head structure shortens, driving the target head structure to switch from the ready state to the folded state.

[0018] Furthermore, the target assembly also includes at least two hit sensors, which are disposed on the target structure to receive corresponding electrical signals or corresponding optical signals; at least two hit sensors are disposed one-to-one with at least two target structures; the windmill target device also includes a central controller; the hit sensors are electrically connected to the central controller; the electric telescopic rod is electrically connected to the central controller; when the hit sensor receives the corresponding electrical signal or corresponding optical signal, the central controller controls the electric telescopic rod corresponding to the target structure to shorten, so as to drive the target structure to switch from a standby state to a folded state.

[0019] According to another aspect of the present invention, a windmill target control method is provided, which is applied to the windmill target device described above. The target assembly includes N target structures, where N is a positive integer and N is greater than or equal to 2. The N target structures are spaced apart circumferentially along the target frame assembly. The windmill target control method includes the following steps: when all target structures have not been hit, a rotary drive assembly is controlled to drive the target frame assembly to rotate at a first rotational speed; after the first target structure is hit, the rotary drive assembly is controlled to drive the target frame assembly to rotate at a second rotational speed; after the second target structure is hit, the rotary drive assembly is controlled to drive the target frame assembly to rotate at a third rotational speed; and so on, after the Nth target structure is hit, the rotary drive assembly is controlled to drive the target frame assembly to rotate at a (N+1)th rotational speed. The first rotational speed, the second rotational speed, and the (N+1)th rotational speed are all different to simulate the scenario where the rotational speed of the other unhit targets changes when the actual target is hit and falls.

[0020] Applying the technical solution of this invention, a windmill target device is provided, comprising: a target head assembly, a target frame assembly, a rotation drive assembly, a reset assembly, and a detection assembly; the target head assembly is disposed on the target frame assembly, the target frame assembly is disposed on the rotation drive assembly, and the rotation drive assembly is drivenly connected to the target frame assembly to drive the target frame assembly and the target head assembly to rotate at a set speed; wherein, the target head assembly has a standby state and a folded state, in the standby state, the target head assembly is positioned facing the firing position; when the target head assembly is physically hit, receives a corresponding electrical signal, or receives a corresponding optical signal, the target head assembly switches from the standby state to the folded state, in the folded state, the target head assembly avoids the firing position to indicate that it has been hit; the detection assembly is used to detect the state of the target head assembly, and the reset assembly is at least used to reset the target head assembly so that the target head assembly changes from the folded state to the standby state.

[0021] This invention, through the coordinated operation of a target head assembly, target frame assembly, rotation drive assembly, reset assembly, and detection assembly, enables the target head assembly to automatically reset, saving time and effort, preventing personnel from entering the firing range, and thus avoiding dangerous situations and improving safety. Simultaneously, by enabling the target head assembly to receive corresponding electrical or optical signals, the windmill target device proposed in this invention can be used for non-impact laser or electromagnetic wave shooting training, greatly expanding its application scenarios and increasing training modes. The reset assembly ensures automatic reset of the target head assembly, significantly reducing the need for manual intervention and improving training efficiency. Overall, the windmill target device proposed in this invention significantly improves the automation level, safety, and versatility of shooting training, providing a more advanced and comprehensive solution for developing shooting skills.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] like Figures 1 to 3 As shown, an embodiment of the present invention provides a windmill target device, including: a target head assembly 10, a target frame assembly 20, a rotation drive assembly 30, a reset assembly 40, and a detection assembly 50; the target head assembly 10 is disposed on the target frame assembly 20, the target frame assembly 20 is disposed on the rotation drive assembly 30, and the rotation drive assembly 30 is drivenly connected to the target frame assembly 20 to drive the target frame assembly 20 and the target head assembly 10 to rotate at a set speed; wherein, the target head assembly 10 has a standby state and a folded state, in the standby state, the target head assembly 10 is positioned facing the firing position; when the target head assembly 10 is physically hit, receives a corresponding electrical signal, or receives a corresponding optical signal, the target head assembly 10 switches from the standby state to the folded state, in the folded state, the target head assembly 10 avoids the firing position to show that it has been hit; the detection assembly 50 is used to detect the state of the target head assembly 10, and the reset assembly 40 is used at least to reset the target head assembly 10 so that the target head assembly 10 changes from the folded state to the standby state.

[0035] This invention, through the coordinated operation of the target head assembly 10, target frame assembly 20, rotation drive assembly 30, reset assembly 40, and detection assembly 50, enables the target head assembly 10 to automatically reset, saving time and effort, preventing personnel from entering the firing range, and thus avoiding dangerous situations and improving safety. Simultaneously, by enabling the target head assembly 10 to receive corresponding electrical or optical signals, this invention allows the proposed windmill target device to be used for non-impact laser or electromagnetic wave shooting training, greatly expanding its application scenarios and increasing training modes. The reset assembly 40 ensures the automatic reset of the target head assembly 10, significantly reducing the need for manual intervention and improving training efficiency. Overall, the windmill target device proposed in this invention significantly improves the automation level, safety, and versatility of shooting training, providing a more advanced and comprehensive solution for developing shooting skills. This invention has a simple structure and low cost, is easy to assemble and maintain, and solves the problems of inconvenient and dangerous manual target head reset, limited training modes, and low automation in existing windmill targets, making it suitable for large-scale promotion and use.

[0036] like Figure 1 As shown, the target assembly 10 includes at least two target structures 11, which are spaced apart circumferentially along the target frame assembly 20. Each target structure 11 has a display surface 111. In the ready state, the display surface 111 faces the firing position and is parallel to or at an angle to the vertical plane. In the folded state, the display surface 111 avoids the firing position and is parallel to or at an angle to the horizontal plane to show that it has been hit. The reset assembly 40 includes a reset motor 41 and a reset structure 42, which is drivenly connected to the reset motor 41. After a target structure 11 in the folded state moves to the reset assembly 40, the reset motor 41 drives the reset structure 42 to rotate, and the reset structure 42 strikes the target structure 11, so that the target structure 11 changes from the folded state to the ready state.

[0037] The target head assembly 10 includes at least two target head structures 11, which are spaced apart circumferentially along the target frame assembly 20. The display surface 111 of the target head structure 11 is parallel to or at a specific angle to the vertical plane in the ready state. When the target head is hit and enters the folded state, the display surface 111 avoids the firing position, becoming parallel to or at an angle to the horizontal plane, visually demonstrating the hit. The reset assembly 40 integrates a reset motor 41, which is driven by a reset structure 42. Once the target head structure 11 slides down to the reset assembly 40 in the folded state, the reset motor 41 immediately drives the reset structure 42 to rotate. Through the impact of the reset structure 42, the target head structure 11 returns from the folded state to the ready state. This design not only avoids the inconvenience and potential danger of manual reset but also ensures the continuous availability and safety of the electric windmill target during training. The tilting and resetting mechanism of the target structure 11, combined with the simulated rotation algorithm of the windmill target, enables the electric windmill target to simulate the dynamic changes after a real target falls during shooting training. At the same time, the automation device ensures the safety and convenience of training.

[0038] like Figure 1 and Figure 3 As shown, the reset structure 42 includes a reset impact wheel 421 and a connecting rod frame 422. At least a portion of the reset impact wheel 421 is made of elastic material to buffer impact. The reset impact wheel 421 is rotatably mounted on the connecting rod frame 422, and the connecting rod frame 422 is driven to be connected to the reset motor 41. The reset motor 41 drives the connecting rod frame 422 to rotate. The windmill target device also includes a base assembly 60, a rotation drive assembly 30 is mounted on the upper part of the base assembly 60, and the base assembly 60 is mounted on the ground. The reset assembly 40 is mounted on the base assembly 60 and is positioned to avoid firing.

[0039] The reset impact wheel 421 and the connecting rod frame 422 are key components of the reset structure 42. At least a portion of the reset impact wheel 421 is made of elastic material to cushion the impact on the target head structure 11, ensuring that the target head structure 11 is not damaged during the reset process. The reset impact wheel 421 is rotatably mounted on the connecting rod frame 422. The reset motor 41 drives the connecting rod frame 422 to rotate, thereby causing the reset impact wheel 421 to strike the tilted target head structure 11 and reset it. The rotation drive assembly 30 is located on the upper part of the base assembly 60, which is stably mounted on the ground, providing stable support for the windmill target device. The reset assembly 40 is also located on the base assembly 60 and is positioned away from the firing position to ensure the safety of shooting training.

[0040] like Figure 1 and Figure 2As shown, the target head structure 11 includes a target head component 112 and a telescopic support rod 113. The target head component 112 is rotatably mounted on the target frame assembly 20. One end of the telescopic support rod 113 is connected to the side of the target head component 112 facing away from the display surface 111, and the other end of the telescopic support rod 113 is connected to the target frame assembly 20. The telescopic support rod 113 is telescopically adjustable and is used to support the target head component 112. In the folded state, the telescopic support rod 113 is shortened so that the display surface 111 avoids the firing position. In the ready state, the telescopic support rod 113 is extended to support the display surface 111 facing the firing position.

[0041] The target head structure 11 includes a target head component 112 and a telescopic support rod 113. The target head component 112 is rotatably mounted on the target frame assembly 20. One end of the telescopic support rod 113 is connected to the side of the target head component 112 facing away from the display surface 111, and the other end of the telescopic support rod 113 is connected to the target frame assembly 20. The telescopic support rod 113 is telescopic and is used to support the target head component 112. By setting the telescopic support rod 113, the target head component 112 has a certain supporting force, thereby ensuring that the target head component 112 will not spontaneously undergo unnecessary state changes when rotating, thus ensuring operational reliability. When the target head (i.e., the target head component 112) is in a folded state, the telescopic support rod 113 is shortened, and the display surface 111 avoids the firing position, facilitating target replacement or maintenance operations. When the target head is in the ready state, the telescopic support rod 113 is extended, firmly supporting the display surface 111 facing the firing position, ensuring the normal conduct of shooting training. The aforementioned dynamic adjustment mechanism not only enhances the interactivity and challenge of the windmill target, but also adapts to various shooting environments and needs.

[0042] like Figure 1 As shown, the target frame assembly 20 includes a support frame 21 and at least two support members 22; the support frame 21 is disposed on the rotary drive assembly 30; the at least two support members 22 are arranged circumferentially spaced along the support frame 21 and extend radially along the support frame 21; the target head structure 11 is disposed at the end of the support member 22 away from the support frame 21; the at least two target head structures 11 are arranged in a one-to-one correspondence with the at least two support members 22.

[0043] The target frame assembly 20 is designed to include a support frame 21 and at least two support members 22. The support frame 21 is securely mounted on the rotary drive assembly 30 to ensure the overall stability and smooth rotation of the target frame (i.e., the target frame assembly 20). The at least two support members 22 are evenly distributed circumferentially along the support frame 21, and each support member 22 extends radially along the support frame 21. The target head structure 11 is located at the end of the support member 22 away from the support frame 21, ensuring that the target head structure 11 can maintain good balance and dynamic stability when the target frame rotates. The target head structure 11 corresponds one-to-one with the support member 22, realizing the precise arrangement and positioning of the target head. The above structural design enables the windmill target to accurately simulate the rotation of the target head when it actually falls after being shot.

[0044] like Figure 1 and Figure 2 As shown, the windmill target device also includes a central controller; the rotation drive assembly 30 is electrically connected to the central controller, which controls the target frame assembly 20 and the target head assembly 10 to rotate at a set speed; the detection assembly 50 includes at least two position sensors 51, which are electrically connected to the central controller. The at least two position sensors 51 are configured one-to-one with at least two target head structures 11. The position sensors 51 are mounted on the target frame assembly 20 and are used to detect the position of the target head structure 11. The central controller determines the state of the corresponding target head structure 11 based on the position information detected by the position sensors 51; the windmill target device also includes a light indicator, which is electrically connected to the central controller; the light indicator displays the state of the target head structure 11 according to the change in display color and / or whether it flashes, so as to indicate whether the target head structure 11 has been hit.

[0045] The rotary drive assembly 30 is electrically connected to the central controller, enabling the target frame assembly 20 and the target head assembly 10 to operate at a set rotation speed under the precise control of the central controller, thus automating the target operation. The detection assembly 50 includes at least two position sensors 51, which are connected to the central controller and arranged one-to-one with at least two target head structures 11 on the target frame assembly 20, capable of real-time monitoring of the position information of the target head structures 11. Based on the data fed back by the position sensors 51, the central controller can quickly determine the state of the target head structure 11, such as whether it has been hit, and then adjust the working state of the rotary drive assembly 30 to simulate the dynamic behavior of a real target after being shot. Furthermore, as part of an optional visual feedback mechanism, a light indicator is electrically connected to the central controller and can adjust its displayed color and / or flashing mode according to changes in the state of the target head structure 11, intuitively reflecting whether the target head structure 11 has been hit, and enhancing the realism and enjoyment of shooting training.

[0046] like Figure 1As shown, the windmill target device also includes a base assembly 60, which includes a movable base 61 and multiple casters 62. The multiple casters 62 are spaced apart below the movable base 61 to jointly support and move the movable base 61. The casters 62 have a locking function to fix the movable base 61. A reset assembly 40 is disposed on the movable base 61 and is positioned to avoid the firing position. The rotation drive assembly 30 includes a drive motor 31 and a support frame 32. The support frame 32 is disposed on the upper part of the movable base 61, and the target frame assembly 20 is rotatably disposed on the support frame 32. The drive motor 31 is disposed on the support frame 32 and is drivenly connected to the target frame assembly 20.

[0047] The base assembly 60 achieves both mobility and stability. It includes a movable base 61 and multiple spaced casters 62, which collectively support the movable base 61 and are equipped with a locking function to secure the base during shooting or movement. A reset assembly 40 is mounted on the movable base 61, cleverly avoiding the shooting position to ensure the continuity and safety of shooting training. The rotation drive assembly 30 includes a drive motor 31 and a support frame 32. The support frame 32 is located on top of the movable base 61, and the target frame assembly 20 is rotatably mounted on the support frame 32. The drive motor 31 is connected to the target frame assembly 20, providing power for the rotation of the target head structure 11. This design allows the windmill target device to not only simulate the rotational behavior of a real target head falling after being shot, but also to automatically reset via the reset assembly 40 without manual intervention, improving the efficiency and safety of shooting training. Furthermore, the movable and stable design of the base assembly 60 allows the device to be flexibly adjusted according to training needs, enhancing the diversity and flexibility of training and further improving the effectiveness of shooting training.

[0048] like Figure 1As shown, the target head assembly 10 includes at least two target head structures 11, which are spaced apart circumferentially along the target frame assembly 20. Each target head structure 11 has a display surface 111. In the ready-to-fire state, the display surface 111 faces the firing position and is parallel to or at an angle to the vertical plane. In the folded state, the display surface 111 avoids the firing position and is parallel to or at an angle to the horizontal plane. The reset assembly 40 includes at least two electrically operated telescopic rods. The target head structures 11 are rotatably mounted on the target frame assembly 20, with one end of each electric telescopic rod facing away from the target head structure 11. One end of the display panel 111 is connected to the other end of the electric telescopic rod, which is connected to the target frame assembly 20. The electric telescopic rod can automatically extend and retract. When the electric telescopic rod is shortened, it drives the display panel 111 to avoid the firing position. When the electric telescopic rod is extended, it drives the display panel 111 to face the firing position. At least two electric telescopic rods are set one-to-one with at least two target head structures 11. When the target head assembly 10 receives the corresponding electrical signal or the corresponding optical signal, the electric telescopic rod corresponding to the target head structure 11 drives the target head structure 11 to switch from the standby state to the folded state by shortening.

[0049] The target head assembly 10 includes at least two target head structures 11, which are arranged circumferentially around the target frame assembly 20. Each target head structure 11 has a display surface 111. In the ready state, the display surface 111 faces the firing position, parallel to or at an angle to the vertical plane; in the folded state, the display surface 111 avoids the firing position, turning to be parallel to or at an angle to the horizontal plane. The reset assembly 40 includes at least two electrically operated telescopic rods. The target head structures 11 are rotatable on the target frame assembly 20. One end of each electric telescopic rod is connected to the side of the target head structure 11 away from the display surface 111, and the other end is fixed to the target frame assembly 20. The electric telescopic rods can automatically adjust their length. By shortening the electric telescopic rods, the display surface 111 is moved to an avoidance firing position; conversely, by extending the electric telescopic rods, the display surface 111 is returned to the firing position. At least two electric telescopic rods are configured one-to-one with the target head structure 11. When the target head structure 11 receives an electrical or optical signal command, the corresponding electric telescopic rod shortens, causing the target head structure 11 to change from a standby state to a folded state. By precisely controlling the movement of the electric telescopic rods, the target head structure 11 can avoid obstacles and be oriented, improving the efficiency and safety of the electric windmill target. It is also suitable for shooting training scenarios with no impact and low impact.

[0050] like Figure 1As shown, the target assembly 10 also includes at least two hit sensors, which are disposed on the target structure 11 and are used to receive corresponding electrical signals or corresponding optical signals. At least two hit sensors are disposed in a one-to-one correspondence with at least two target structures 11. The windmill target device also includes a central controller. The hit sensors are electrically connected to the central controller. The electric telescopic rod is electrically connected to the central controller. When the hit sensor receives the corresponding electrical signal or the corresponding optical signal, the central controller controls the electric telescopic rod corresponding to the target structure 11 to shorten, so as to drive the target structure 11 to switch from the standby state to the folded state.

[0051] The target assembly 10 includes not only the target structure 11 but also integrates at least two hit sensors, each corresponding to a different target structure 11, for receiving electrical or optical signals. The entire windmill target device is also equipped with a central controller, which is electrically connected to the hit sensors and the electric telescopic rod. When the hit sensor detects a hit signal, the central controller immediately controls the electric telescopic rod aligned with the target structure 11 to shorten, thereby quickly driving the target structure 11 from a standby state to a folded state, achieving target tilting. This technical solution not only ensures the immediacy and accuracy of the target response but also automates target tilting. The introduction of hit sensors is particularly suitable for non-impact shooting training and low-impact shooting training scenarios, such as laser shooting and BB gun shooting, making training methods more diverse. Through precise control of the electric telescopic rod, the target tilting action is more realistic and controllable, further enhancing the simulation effect of training.

[0052] This invention also proposes a windmill target control method. The target assembly 10 includes N target structures 11, where N is a positive integer and N is greater than or equal to 2. The N target structures 11 are spaced apart circumferentially along the target frame assembly 20. The windmill target control method includes the following steps: when all target structures 11 have not been hit, the rotation drive assembly 30 is controlled to drive the target frame assembly 20 to rotate at a first rotational speed; after the first target structure 11 is hit, the rotation drive assembly 30 is controlled to drive the target frame assembly 20 to rotate at a second rotational speed; after the second target structure 11 is hit, the rotation drive assembly 30 is controlled to drive the target frame assembly 20 to rotate at a third rotational speed; and so on, after the Nth target structure 11 is hit, the rotation drive assembly 30 is controlled to drive the target frame assembly 20 to rotate at the (N+1)th rotational speed. The first rotational speed, the second rotational speed, and the (N+1)th rotational speed are all different to simulate the scenario where the rotational speed of other unhitted targets changes when an actual target is hit and falls.

[0053] Each target structure 11 of the target assembly 10 can rotate stably at a first rotational speed when not hit. When the target structures 11 are successively hit and switch to a folded state, the rotation drive component 30 immediately adjusts the rotational speed of the target frame assembly 20, changing it to a second, third, and so on up to the (N+1)th rotational speed, with each adjustment resulting in a different speed. This dynamic speed adjustment design accurately simulates the real scenario of a target being hit and falling, affecting the rotational speed of other targets, thus enhancing the realism and challenge of shooting training. Furthermore, by monitoring the changes in the state of the target assembly 10 in real time through the detection component 50, combined with the timely response of the rotation drive component 30, the rotational characteristics of the target frame assembly 20 can quickly adapt to the hit state of the target structures 11, thereby achieving instant adjustment of the training scenario and improving the effectiveness and interactivity of shooting training.

[0054] The specific working process and principle of one embodiment of the present invention will now be described in detail as follows:

[0055] The target head structure 11 of the electric windmill target of the present invention will not fall off after being hit, but will tilt. Through simulation calculation, based on the position of the hit target head structure 11 and the state of the windmill target before being hit, the rotational acceleration and other information when the target head actually falls are calculated. The rotation drive component 30 is then controlled to drive the target frame assembly 20 to simulate the rotation of the windmill target when the target head actually falls. Specifically, when the target head structures 11 are not hit, the rotation drive component 30 drives the target frame assembly 20 to rotate at a first rotational speed; after the first target head structure 11 is hit, the rotation drive component 30 drives the target frame assembly 20 to rotate at a second rotational speed; after the second target head structure 11 is hit, the rotation drive component 30 drives the target frame assembly 20 to rotate at a third rotational speed; and so on. The simulated actual rotation parameters (including the mathematical and mechanical logic of the first rotational speed, the second rotational speed, and the (N+1)th rotational speed) are calculated using the following formula:

[0056] For each target structure 11 that is hit, the following calculation can be performed once:

[0057] 1. Calculate the actual position of the centroid:

[0058]

[0059]

[0060]

[0061] Let be the initial angle of the i-th target. This refers to the total number of target heads (i.e., the number of target head structures 11). Let r be the position vector of the i-th target head (i.e., target head component 112), and r be the distance between the target head and the center of rotation. Let be the rotation angle of the system at time t. Let be the position vector of the system's centroid. The number of surviving targets;

[0062] 2. Calculate the total torque of the actual system, which is approximately equal to the actual gravitational torque:

[0063]

[0064]

[0065] For the total torque of the system, Let m be the gravitational torque, m be the mass of a single target, and g be the gravitational acceleration (9.8 m / s²). 2 ), Let x be the centroid coordinate. x-coordinate of the rotation center

[0066] Calculate the actual moment of inertia:

[0067]

[0068] Calculate the actual angular velocity:

[0069]

[0070] Angular acceleration at time t

[0071] 3. Calculate the output torque required to simulate actual rotation:

[0072]

[0073]

[0074] This is the actual moment of inertia. Let ω be the angular velocity at time t. is the time step, i.e. the time interval for updating the angular velocity, and c is the damping coefficient, which can be 0.01.

[0075] The target head structure 11 of the electric windmill target of the present invention does not fall off after being hit, but tilts over. It can be automatically reset by the reset component 40. The reset is performed after shooting training or after the target head structure 11 tilts over. The reset component 40 is activated when the windmill target rotates one revolution. When the target head structure 11 reaches the reset position, the reset motor 41 drives the connecting rod frame 422 to rotate, which in turn drives the reset impact wheel 421 to hit the tilted target head structure 11 and reset the target head structure 11. This saves time and effort, and the staff does not need to enter the shooting range, avoiding dangerous situations.

[0076] Furthermore, the electric windmill target of the present invention is equipped with a hit sensor on each target head, enabling the windmill target to be used for non-impact shooting training (e.g., laser shooting) and low-impact shooting training (e.g., BB gun shooting). When the hit sensor detects that the target head has been hit, the target head is tilted to simulate the effect of a live bullet hitting the target. In addition, the electric windmill target of the present invention can also be equipped with a light indicator. After the target head is tilted, the light state of the corresponding light indicator is changed (light on / off state, color change, light flashing, etc.), which intuitively reflects the hit status of the target head structure 11, enhancing the realism and fun of shooting training.

[0077] In summary, this invention provides a windmill target device and a windmill target control method. By configuring the target head assembly 10, target frame assembly 20, rotation drive assembly 30, reset assembly 40, and detection assembly 50 to work together, the target head assembly 10 can automatically reset, saving time and effort, preventing personnel from entering the firing range, thus avoiding dangerous situations and improving safety. Simultaneously, by configuring the target head assembly 10 to receive corresponding electrical or optical signals, this invention enables the windmill target device to be used for non-impact laser or electromagnetic wave shooting training, greatly expanding its application scenarios and increasing training modes. The reset assembly 40 ensures the automatic reset of the target head assembly 10, significantly reducing the need for manual intervention and improving training efficiency. Overall, the windmill target device proposed in this invention significantly improves the automation level, safety, and versatility of shooting training, providing a more advanced and comprehensive solution for the cultivation of shooting skills. The invention has a simple structure and low cost, is easy to assemble and maintain, and solves the problems of inconvenient and dangerous manual target reset, relatively simple training modes, and low degree of automation in existing windmill targets, making it suitable for large-scale promotion and use.
