Description

Technical Field

[0001] This invention relates to a target shape changing mechanism, specifically a multi-target shape switching device, belonging to the field of military training equipment. Background Technology

[0002] Currently, the simulation of various tactical postures is achieved individually by lifting and lowering targets and carrying target plates of different shapes, such as head targets, chest targets, humanoid targets, tank frontal targets, and bunker targets, each simulating a tactical posture. The display format is relatively simple and deviates greatly from the actual combat units' use of various tactical actions to complete combat missions in actual combat. Furthermore, the target plates need to be manually changed during training.

[0003] On August 30, 2019, Chinese utility model patent CN201822242469.2 disclosed a multi-target, multi-pose display device for robots. This device uses a single control system to control multiple targets to work collaboratively, each target carrying a target plate simulating different poses. The control system provides timing control for each target, displaying them one by one to achieve multi-target, multi-pose display. However, this technical solution, which uses multiple targets to work collaboratively to simulate tactical poses, requires numerous tilting mechanisms, resulting in high costs. Furthermore, the multi-target simulation represents the tactical poses of multiple independent combat units, rather than the simulation of multiple tactical poses of a single combat unit.

[0004] On April 29, 2019, Chinese invention patent application CN201910353380.X disclosed an omnidirectional attitude simulation target device. This device comprises a control unit, a lifting adjustment unit, a steering adjustment unit, a tilt adjustment unit, and a target. The control unit is connected to the target through the lifting, steering, and tilt adjustment units to adjust the target's height, steering, and tilt angle, thus simulating attitude. However, this design uses a control unit to control the lifting, steering, and tilt adjustment units, each with its own corresponding motor drive. This results in numerous drive joints, high cost, and complex ballistic protection and maintenance in the later stages.

[0005] Furthermore, in existing products, a single rotating mechanism is used to divide the radial direction of the output shaft into 0°, 90°, 180°, and 360° angles at 90° intervals. Different target plates with different postures are fixed in each direction. When the rotating mechanism rotates, all target plates rotate around the rotating axis. When the target plate in each of the aforementioned angle directions rotates to a vertically upward position, it simulates the tactical posture corresponding to that target shape. This method uses a single mechanism to carry multiple rotating targets, requiring a large deployment space and a wide variety of posture target plates, significantly increasing technical difficulty and manufacturing costs, and reducing training organization efficiency. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a multi-target switching device that can quickly and independently realize the arbitrary switching of the tactical posture of the combat unit and more realistically simulate the tactical actions of the combat unit in actual combat.

[0007] To solve the above-mentioned technical problems, the present invention provides a multi-target switching device, including a target frame, a target plate, a drive mechanism and a base, wherein the target frame includes two power sides and two fixed sides;

[0008] The target plate includes an upper target plate and a lower target plate;

[0009] One end of the first fixed side is hinged to the base, and the other end is hinged to one end of the first power side; the first fixed side is set in a vertical state and can be tilted backward and returned to its fixed position.

[0010] The second power side is located in front of the first fixed side, and one end of the second power side is connected to the drive mechanism and can rotate around the drive mechanism; the two ends of the second fixed side are respectively hinged to the other ends of the first power side and the second power side.

[0011] The upper target plate is fixedly connected to the second fixed edge, and the lower target plate is fixedly connected to the second power edge. When the two power edges are in a vertical state, the upper target plate and the lower target plate are located in the same plane.

[0012] The second power side is provided with a toggle block corresponding to the position of the first fixed side.

[0013] The beneficial effects of the present invention are as follows: (1) The target frame adopts an approximately parallelogram structure formed by two dynamic sides and two fixed sides. By restricting the degree of freedom of movement of the fixed sides, the dynamic side of the driving mechanism is rotated, thereby driving the dynamic change of the target frame shape and realizing the multi-angle change of the target frame; (2) When the fixed side is positioned in a vertical state, during the rotation of the dynamic side between the vertical and horizontal states, the upper target plate remains vertical and the target shape remains unchanged. The vertical projection height of the lower target plate changes dynamically. At this time, the projections of the upper and lower target plates on the vertical plane form a changing simulated target plate, which can simulate different tactical postures of combat units; (3) By adopting an approximately parallelogram-shaped target frame and simulated target plate for division, the present invention realizes the arbitrary switching of multiple tactical postures, more realistically simulating the tactical actions of combat units in actual combat, so as to meet the needs of close to actual combat; (4) The present invention uses a single falling target to realize the arbitrary switching of multiple tactical postures, more realistically simulating the tactical actions of combat units in actual combat, greatly improving the training effect and reducing the training cost.

[0014] In this invention, there are two target frames, which can further improve the working efficiency and stability of the device and extend its service life.

[0015] In this invention, the first fixed side is connected to a pre-tightening limiting mechanism. The pre-tightening limiting mechanism enables the target frame to be quickly tilted, lowered, and returned to its original position.

[0016] In this invention, the pre-tightening limiting mechanism includes a fixed lug, a torsion spring, and a limiting block. The fixed lug is located on one side of the first fixed edge. The torsion spring is connected to the fixed lug and the first fixed edge respectively. One end of the limiting block is fixedly connected to the fixed lug, and the other end extends towards the first fixed edge to a position overlapping with the first fixed edge.

[0017] In this invention, the second power edge is connected to the drive mechanism via a target clamp, which facilitates the disassembly, transportation, and repair of the device. Attached Figure Description

[0026] The components are: 1-target body, 2-fixed side, 3-base, 4-target clamp, 5-powered side, 6-bulletproof plate, 7-target plate below chest, 8-chest target plate, 9-limiting block, 10-fixed support lug, 11-torsion spring, 12-moving block. Detailed Implementation

[0027] The invention will now be further described in detail below, taking the humanoid target as an example to simulate the tactical posture of an individual soldier, in conjunction with the accompanying drawings.

[0028] like Figures 1 to 8As shown, the multi-target switching device of the present invention includes a target body 1, a fixed side 2, a base 3, a target clamp 4, a power side 5, a bulletproof plate 6, a target plate below the chest 7, a chest target plate 8, a limiting block 9, a fixed support lug 10, a torsion spring 11, and a toggle block 12. The fixed side 2 and the power side 5 each consist of two parts: a first fixed side 2-1, a second fixed side 2-2, a first upper power side 5-1, and a second power side 5-2. The first fixed side 2-1, the second fixed side 2-2, the first upper power side 5-1, and the second power side 5-2 can be connected to form a target frame that approximates a parallelogram. In this embodiment, there are two target frames with identical structures; however, this embodiment will describe a single target frame structure.

[0029] The target body 1 is fixedly mounted on the base 3. A power unit is located inside the target body 1 to provide power to the device. The target body 1 can be implemented using a structure commonly used in the prior art, with the output shafts of the target body 1 located on both sides. In this invention, the power unit is a drive motor; however, those skilled in the art should understand that the power unit can also be implemented using other mechanisms.

[0030] Both target clamps 4 are mounted on the output shaft of the drive unit in the target body 1. One end of the second moving edge 5-2 is inserted into and fixed in the target clamp 4. The second moving edge 5-2 is provided with a toggle block 12 corresponding to the position of the first fixed edge 2-1. When the second moving edge 5-2 rotates backward to tilt the target, the toggle block 12 can apply a force to the first fixed edge 2-1, causing the first fixed edge 2-1 to tilt backward.

[0031] The first fixed edge 2-1 is located on the rear side of the target clamp 4, and its bottom end is hinged to the base 3. A fixed lug 10 is provided on the outer side of the first fixed edge 2-1, and the fixed lug 10 is basically aligned with the first fixed edge 2-1. The fixed lug 10 is fixed to the base 3, and a limiting block 9 is installed on the fixed lug 10. The limiting block 9 extends towards the first fixed edge 2-1 and overlaps with the first fixed edge 2-1 to facilitate blocking and positioning of the first fixed edge 2-1. A torsion spring 11 is connected between the fixed lug 10 and the first fixed edge 2-1. The torsion spring 11 can provide a rotational force to the first fixed edge 2-1 to ensure that the target frame can be quickly tilted from a planar position to a vertical position. The limiting block 9 is used to restrict the degree of freedom of the first fixed edge 2-1 to rotate forward, that is, to restrict and keep the first fixed edge 2-1 in a vertical position.

[0032] One end of the first power edge 5-1 is hinged to the upper end of the first fixed edge 2-1, and the other ends of the first power edge 5-1 and the second power edge 5-2 are respectively hinged to both ends of the second fixed edge 2-2. Thus, a target frame that approximates a parallelogram is formed with the two fixed edges 2 and the two power edges 5 as its side lengths.

[0033] The power unit inside the target body 1 drives the second power edge 5-2 to rotate around the output shaft of the target body 1 from a horizontal state to a vertical state, thereby realizing the dynamic deformation of the parallelogram target frame.

[0034] In this embodiment, the human-shaped target plate is divided into a chest target plate 8 and a target plate for the lower chest area 7. The chest target plate 8 is installed on the first fixed side 2-2, and the target plate for the lower chest area 7 is installed on the second powered side 5-2. The target plate for the lower chest area 7 is located on the upper part of the second powered side 5-2. When the powered side 5-2 is in a vertical state, the chest target plate 8 and the target plate for the lower chest area 7 are joined together on the same vertical plane to simulate a standing posture.

[0035] As shown in the attached figures, in this embodiment, two target frames are used. The chest target plate 8 is mounted on the second fixed side 2-2 of the two target frames, and the target plate below the chest is mounted on the second powered side 5-2 of the two target frames. The two fixed sides 2 are fixed vertically. During the rotation of the two powered sides 5 between vertical and horizontal states, the chest target plate 8 remains vertical, and the target shape remains unchanged. The vertical projection height of the target plate below the chest 7 dynamically changes. At this time, the projections of the chest target plate 8 and the target plate below the chest 7 on the vertical plane form a changing simulated target plate, which can simulate different tactical postures of combat units, such as... Figure 2 As shown.

[0036] like Figure 3 As shown, a bulletproof plate 6 is provided at the front end of the base 3. The height of the bulletproof plate 6 is lower than that of the chest target plate. When the lower edge of the chest target plate 8 and the upper edge of the bulletproof plate 6 are on the same horizontal plane, the target plate 7 below the chest is tilted and hidden behind the bulletproof plate 6, simulating a kneeling position.

[0037] like Figure 4 As shown, the lower half of the chest target plate 8 is hidden behind the ballistic plate 6. The ballistic plate 6 covers the lower half of the chest target plate 8, leaving only the head target shape exposed, simulating a prone position.

[0038] like Figure 5 and 6 As shown, when the entire target plate is tilted from the standing position, the power unit in the target body 1 drives the second power edge 5-2 to rotate backward. The actuating block 12 on the second power edge 5-2 applies a force to the first fixed edge 2-1 to overcome the preload provided by the torsion spring 11, so that the two fixed edges 2 and the two power edges 5 are on the same plane and together achieve the tilting of the target.

[0039] like Figure 7 and 8As shown, during the rotation of the two power edges 5 from a vertical to a horizontal state, the chest target plate 8 remains vertical and its height remains unchanged, while the vertical projection height of the target plate 7 below the chest changes dynamically. The projections of the chest target plate 8 and the target plate 7 below the chest on the vertical plane form a changing human-shaped target plate, which can simulate different tactical postures of individual soldiers, improve the realism of the human-shaped target plate, and improve the training effect.

[0040] like Figure 1 , 2 As shown in Figure 5, when the humanoid target is launched from the inverted state, the actuating block 12 on the second power edge 5-2 releases the force on the first fixed edge 2-1, and the torsion spring 11 applies a rotational force to the first fixed edge 2-1, causing the parallelogram target frame to quickly rise and fall in a planar manner. At this time, the drive unit of the target body 1 drives the second power edge 5-2 to rotate forward, and the first fixed edge 2-1 follows the second power edge 5-2 to rotate forward. When the first fixed edge 2-1 is in a vertical state, the limiting block 9 restricts the degree of freedom of the first fixed edge 2-1 to rotate forward. At this time, the second fixed edge 2-2 remains vertical, and the shape of the parallelogram target frame dynamically changes.

[0041] This invention provides a concept and method for a multi-target switching device. Many methods and approaches exist for implementing this technical solution; the above description is merely a preferred embodiment of the invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications should also be considered within the scope of protection of this invention. All components not explicitly stated in this embodiment can be implemented using existing technologies.
