[0027] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0028] like Figures 1 to 5 As shown, the armored vehicle shooting gun target hidden and visible target machine in this embodiment includes a frame welding 1, a circuit board box 2, a battery box assembly 3, an upper cover plate 4, a left target arm assembly 5, a bearing seat 6, a self-aligning ball bearing 7, a reduction motor shaft 8, a reduction motor 9, a flat key 10, a right target arm assembly 11, a limit switch bracket assembly 12, a first Hall sensor bracket 13, a first Hall sensor 14, a baffle 15, a first limit switch 16, a second limit switch 17, a magnetic steel 18, a second Hall sensor 19, a second Hall sensor bracket 20, a motor fixing bracket 21, an arc plate 22, an ear plate 23, and a control unit 24.

[0029] The circuit board box 2 and the battery box assembly 3 are installed on the frame welding 1. The upper cover plate 4 can cover the frame welding 1 and provide protection for the components inside the upper cover plate 4. The circuit board box 2 is used to install the control unit 24; in this embodiment, the control unit 24 can be realized by using existing technology, so it will not be described in detail in the embodiment. The battery box assembly 3 is mainly used to supply power to the reduction motor 9.

[0030] The motor fixing frame 21 is fixedly installed inside the frame welding 1, and mainly plays the role of supporting the reduction motor 9. The reduction motor shaft 8 and the reduction motor 9 are provided with keyways, and the two are closely matched through the left and right flat keys 10. When the reduction motor 9 rotates, it drives the rotation of the reduction motor shaft 8. The two ends of the reduction motor shaft 8 pass through the bearing seats 6 and the self-aligning ball bearings 7 on the left and right sides respectively.

[0031] The two bearing seats 6 and the two self-aligning ball bearings 7 are respectively fixed on both sides of the frame welding 1, which can effectively ensure the smoothness of the reduction motor shaft 8 during rotation and provide stable support for it.

[0032] The left and right ends of the reduction motor shaft 8 are respectively connected to the left target arm assembly 5 and the right target arm assembly 11, thereby driving them to rotate with the rotation of the reduction motor shaft 8. The left target arm assembly 5 and the right target arm assembly 11 are used to connect and fix various targets, and the left target arm assembly 5 and the right target arm assembly 11 are symmetrically arranged on both sides of the reduction motor shaft 8. The left target arm assembly 5 and the right target arm assembly 11 are connected, which can not only improve stability, but also ensure the consistency of the two when hidden and displayed.

[0033] The first limit switch 16 and the second limit switch 17 are both connected and fixed to the limit switch frame assembly 12 , and the limit switch frame assembly 12 is fixed on the upper top surface of the reduction motor 9 .

[0034] The first Hall sensor 14 is fixed by the first Hall sensor bracket 13, and the first Hall sensor bracket 13 is fixed on the reduction motor 9. The second Hall sensor 19 is fixed by the second Hall sensor bracket 20, and the second Hall sensor bracket 20 is fixedly mounted on the limit switch bracket assembly 12, and the limit switch bracket assembly 12 is mounted on the upper top surface of the reduction motor 9. The first Hall sensor 14 and the second Hall sensor 19 are both electrically connected to the control unit 24. In this embodiment, the first Hall sensor 14 and the second Hall sensor 19 form a 90° angle.

[0035] In this embodiment, the first Hall sensor 14 is disposed between the first limit switch 16 and the second limit switch 17 .

[0036] An ear plate 23 is provided in the middle of the baffle 15, and a round hole is provided on the ear plate 23. The magnet 18 is installed in the round hole of the ear plate 23. The baffle 15 is fixedly installed on the reduction motor shaft 8 and rotates with the rotation of the reduction motor shaft 8. The arc plate 23 is connected to the motor fixing frame 21. A shock-absorbing rubber ring is provided between the arc plate 23 and the reduction motor 9. The arc plate 23 and the motor fixing frame 21 are used to fix the reduction motor 9 to reduce the vibration generated when it rotates.

[0037] When the control operation is performed, the power switch on the circuit board box 2 is turned on to power the entire target drone system. When the target drone "display target" operation is required, the control unit 24 controls the reduction motor 9 to start rotating clockwise, and the baffle 15 rotates with the rotation of the reduction motor shaft 8. When the baffle 15 rotates to Figure 2When the device is in the position shown, the magnet 18 on the baffle 15 contacts the second Hall sensor 19, and the second Hall sensor 19 receives the magnetic signal of the magnet 18 and feeds it back to the control unit 24. The control unit 24 triggers the self-locking of the reduction motor 9, so that it cannot continue to rotate, and the device automatically stops in place; if the second Hall sensor 19 fails at this time and cannot be completely locked, the front end of the baffle 15 contacts the first limit switch 16, and the first limit switch 16 blocks the baffle 15, so that the device cannot continue to rotate clockwise, which plays a role of mechanical "brake" protection, such as Figure 4 shown.

[0038] When the target drone "hidden target" operation is required, the control unit 24 controls the reduction motor 9 to start rotating counterclockwise, and the baffle 15 rotates with the rotation of the reduction motor shaft 8. Figure 3 When the first Hall sensor 14 is in the position, the magnet 18 on the baffle 15 contacts the first Hall sensor 14, and the first Hall sensor 14 receives the magnetic signal of the magnet 18 and feeds it back to the control unit 24, and the control unit 24 triggers the self-locking of the reduction motor 9, so that it cannot continue to rotate, and the device automatically stops in place; similarly, if the first Hall sensor 14 fails and cannot be completely locked, the rear end of the baffle 15 contacts the second limit switch 17, and the second limit switch 17 blocks the baffle 15, so that the device cannot continue to rotate clockwise, which plays a role of mechanical "brake" protection, such as Figure 5 shown.

[0039] In actual applications, when remote control operations are required, an existing wireless communication device can be added to the control unit 24 to receive remote control system control commands and execute corresponding hidden and visible actions, thereby realizing remote control of the target machine's hidden and visible operations.

[0040] In the above description, many specific details are elaborated to facilitate a full understanding of the present invention. However, the above examples are merely preferred implementation methods of the present invention and cannot be used to limit the scope of rights of the present invention. Simple modifications and equivalent changes made to the above examples based on the essence of the present invention still fall within the scope of the present invention.
