A mobile target vehicle that facilitates the assembly and disassembly of humanoid targets.

Abstract

This invention proposes a mobile target vehicle for easy assembly and disassembly of a humanoid target, comprising: a drive frame, a machine head at one end of the drive frame, a steering block at the other end of the drive frame, a drive motor on the outer side of the machine head, an output shaft at the end of the drive motor, a rack rotatably mounted in the center of the steering block, and two sets of sliding channels in the center of the drive frame through which the rack passes, connecting to the rack and the drive motor at both ends respectively. This invention achieves multi-directional force balance during target movement by using sliding strips in trapezoidal grooves on both sides of the drive frame in conjunction with four symmetrical sets of rotating rollers on the mobile support. The trapezoidal cross-section design of the sliding strips increases the contact area of ​​the rotating rollers, preventing rolling deviation; the symmetrical arrangement of the four sets of rollers forms a stable support structure, effectively counteracting the lateral torque during belt traction. This design allows the target to maintain a linear trajectory during high-speed movement, reduces wear on the rollers and sliding strips, and significantly improves movement stability.

Description

Technical Field

[0001] This utility model relates to the field of shooting training equipment technology, and in particular to a mobile target vehicle that facilitates the assembly and disassembly of human-shaped targets. Background Technology

[0002] As an important piece of equipment for shooting training, the core function of a mobile target vehicle is to simulate dynamic targets, helping trainees improve shooting accuracy and reaction speed. Traditional mobile target vehicles mostly use fixed target structures or simple sliding rail designs, which have significant shortcomings in practical applications.

[0003] First, the target assembly and disassembly are not convenient enough. In particular, when switching between different types of target plates such as human-shaped targets and ring targets, tools are often needed to remove bolts or adjust brackets. The operation is cumbersome and time-consuming, making it difficult to meet the training needs of rapid switching between multiple subjects.

[0004] Secondly, the target vehicle has poor stability. Conventional sliding rail mechanisms use single-sided rollers or flat slides, which can easily cause the target to sway, deviate, or even get stuck when moving at high speed or changing direction. This causes the trajectory to deviate from the preset path, affecting the accuracy of shooting assessment.

[0005] In addition, traditional transmission systems mostly rely on a single belt or gear drive. Long-term operation can easily lead to transmission errors due to belt stretching and gear wear, making it difficult to maintain uniform speed or precise start-stop control, thus limiting the ability to simulate complex tactical maneuvers.

[0006] In target position detection, existing technologies often use mechanical limit switches or encoders to indirectly measure displacement. These methods are susceptible to interference from mechanical vibrations and transmission clearances, resulting in low dynamic detection accuracy and an inability to provide real-time feedback on the target's actual motion. Furthermore, the structural design of most mobile target vehicles does not adequately consider the compatibility with different target types. For example, humanoid targets, due to uneven center of gravity distribution, are prone to tilting of the moving support after installation, exacerbating wear on the guide mechanism. Although some improvements attempt to enhance stability by increasing the number of guide wheels or optimizing motor control algorithms, they do not fundamentally solve systemic problems such as rapid target replacement, coordinated control of motion mechanisms, and long-term reliability. Therefore, there is an urgent need for a mobile target vehicle that integrates an efficient assembly / disassembly structure, high-precision motion control, and a stable guidance system to meet the higher requirements of modern shooting training for multi-target compatibility, rapid response, and realistic scenario simulation. Utility Model Content

[0007] (a) Technical problems to be solved

[0008] In view of the shortcomings of the existing technology, this utility model provides a mobile target vehicle that is easy to assemble and disassemble humanoid targets, and solves the technical problem of stability of the mobile target vehicle.

[0009] (II) Technical Solution

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] A mobile target vehicle for easy assembly and disassembly of humanoid targets, including

[0012] The drive frame has a machine head at one end and a steering block at the other end. A drive motor is located on the outside of the machine head, and an output shaft is located at the end of the drive motor. A belt is installed on the outer ring of the output shaft. A rack is rotatably mounted in the middle of the steering block. Two sets of sliding channels are set in the middle of the drive frame. The rack passes through the two sets of sliding channels of the drive frame and is connected to the rack and the drive motor at both ends to form a closed loop. A movable bracket is slidably mounted on the outside of the drive frame. A target plate is fixedly mounted on the top of the movable bracket. The drive motor drives the target plate to move horizontally along the drive frame, thereby realizing the control of the target plate's movement.

[0013] Preferably, the movable support includes a lower fixed plate, which is a flat plate structure block, and an upper connecting block is rotatably installed in the middle of the lower fixed plate to fix the target plate.

[0014] Preferably, a rotating roller is located on the outer side below the lower fixed plate, and a connecting block is provided in the middle of the belt. The lower fixed plate is fixedly installed through the connecting block. When the target needs to be moved, the drive motor drives the belt through the output shaft, and the belt moves the lower fixed plate and the target plate above it to slide along the direction of the drive frame, thereby realizing the movement control of the target plate.

[0015] Preferably, trapezoidal grooves are provided on both sides of the drive frame, and two sets of slide bars are provided in the trapezoidal grooves. Rotating rollers are slidably installed on the outside of the slide bars. The movement of the target plate is guided by the rotating rollers sliding on the outside of the slide bars, thereby improving the smoothness of the target plate movement.

[0016] Preferably, the other four sets of rotating rollers are symmetrically distributed to improve stability and better detect the accuracy of the target.

[0017] Preferably, an optoelectronic device is installed above the head of the machine, and a reflector is installed below the moving support. The optoelectronic device is a photoelectric sensor. The optoelectronic device emits photoelectric light, which is reflected back to the optoelectronic device after illuminating the reflector, so as to achieve precise control of the target plate position. The optoelectronic device can detect the position and speed of the target plate movement, and after feedback, control the speed of the drive motor to indirectly control the speed of the target plate. This better assists in simulating different movement speeds and improves the simulation quality and training effect of target shooting.

[0018] Preferably, the target plate is the target used for testing, and a ring target or a human-shaped target is selected according to the testing requirements.

[0019] Preferably, the drive frame is a long strip-shaped groove.

[0020] (III) Beneficial Effects

[0021] 1. By cooperating with the slide bars in the trapezoidal grooves on both sides of the drive frame and the four sets of symmetrical rotating rollers of the moving bracket, multi-directional force balance is achieved during the movement of the target plate. The trapezoidal cross-section design of the slide bars increases the contact area of ​​the rotating rollers and avoids rolling deviation. The symmetrical arrangement of the four sets of rollers forms a stable support structure, which effectively counteracts the lateral torque when the belt is pulled. This design enables the target plate to maintain a linear trajectory during high-speed movement, reduces positioning errors caused by vibration, and reduces wear on the rollers and slide bars, significantly improving the smoothness of movement. In addition, the trapezoidal groove structure can prevent foreign objects from entering the slide rail, ensuring the reliability of long-term use.

[0022] The photoelectric device on the top of the machine head and the reflector at the bottom of the moving support form a closed-loop detection system. It achieves precise control by dynamically capturing the real-time position data of the target plate. When the drive motor drives the moving support through the belt, the photoelectric device continuously emits / receives reflected light signals to accurately calculate the instantaneous displacement and speed of the target plate. This data is fed back to the motor control system in real time to dynamically adjust the output shaft speed, so that the target plate can realize complex motion modes such as speed change and emergency stop according to the preset program. Compared with the traditional encoder detection solution, this photoelectric system directly monitors the moving support body, avoiding the accumulation of transmission chain errors. It can maintain positioning accuracy, especially in high-speed reciprocating motion, and significantly improves the realism of simulated shooting training.

[0023] 3. The upper connecting block of the mobile support adopts a universal rotating structure, which allows the center of gravity of different target plates to be adaptively adjusted through the connecting block. When changing the target type, the ball joint structure of the upper connecting block automatically compensates for the positional deviation between the center of gravity of the target and the support point of the mobile support, avoiding the problem of unilateral pressure on the rotating roller due to the asymmetry of the target. At the same time, the lower fixed plate and the belt can be quickly disassembled and assembled through the modular connecting block. Combined with the standardized interface design of the upper connecting block, the target plate can be replaced with "one click", meeting the needs of continuous training of multiple subjects.

[0024] The closed-loop transmission system, consisting of a rack and pinion in the steering block and a double sliding channel in the drive frame, achieves efficient power transmission through rack-belt composite transmission. The 90° steering design of the rack at the steering block converts the rotational motion of the drive motor into bidirectional linear traction of the belt, reducing belt tensile stress compared to the traditional single-sided traction method. The double sliding channel structure provides full-range guidance for the rack, preventing tooth distortion during long-stroke motion. Especially under rapid acceleration conditions, the elasticity of the belt can buffer the start-stop impact, while the rigid transmission of the rack ensures displacement accuracy. The combined work of the two gives the system both high response speed and long service life. Attached Figure Description

[0031] This application provides a mobile target vehicle that facilitates the assembly and disassembly of humanoid targets, solving the stability problem of existing mobile target vehicles. The mobile target vehicle improves motion stability through a symmetrical guiding structure of slide bar 44 and four sets of rotating rollers 43, preventing the target plate 3 from shifting. The optoelectronic device 6 and the reflector 5 form a closed-loop detection system, which controls the drive motor 7 in real time to achieve precise displacement control. The rotation design of the upper connecting block 42 is adapted to different target types for quick assembly and disassembly, ensuring the balance of the center of gravity. The composite transmission system of rack 9 and belt 10 takes into account both power response and durability.

[0032] Example 1

[0033] The technical solution in this application embodiment is to solve the control problem of the aforementioned mobile target vehicle, and the overall idea is as follows:

[0034] To address the problems existing in the prior art, this utility model provides a mobile target vehicle for easy assembly and disassembly of humanoid targets, including...

[0035] like Figure 1-2As shown, a drive frame 2 is a long, narrow structure. A machine head 1 is mounted at one end of the drive frame 2, and a steering block 8 is mounted at the other end. A drive motor 7 is mounted on the outer side of the machine head 1, and an output shaft is located at the end of the drive motor 7. A belt 10 is mounted on the outer ring of the output shaft. A rack 9 is rotatably mounted in the middle of the steering block 8. Two sets of sliding channels are provided in the middle of the drive frame 2. The rack 9 passes through these two sets of sliding channels and is connected to the rack 9 and the drive motor 7 at both ends, forming a closed loop. A movable support 4 is slidably mounted on the outer side of the drive frame 2. A target plate 3 is fixedly mounted on top of the movable support 4. The target plate 3 is the target used for testing; a ring target or a human-shaped target is selected according to the testing requirements. The drive motor 7 drives the target plate 3 to move horizontally along the drive frame 2, thus controlling the movement of the target plate 3.

[0036] comprehensive Figure 3-4 As shown, the movable support 4 includes a lower fixed plate 41, which is a flat plate structure block. An upper connecting block 42 is rotatably installed in the middle of the lower fixed plate 41. The target plate 3 is fixedly installed through the upper connecting block 42. A rotating roller 43 is rotatably installed on the outer side below the lower fixed plate 41. A connecting block is provided in the middle of the belt 10. The lower fixed plate 41 is fixedly installed through the connecting block. When the target needs to be moved, the drive motor 7 drives the belt 10 through the output shaft. The belt 10 moves the lower fixed plate 41 and the target plate 3 above it to slide along the direction of the drive frame 2, thereby realizing the movement control of the target plate 3.

[0037] The drive frame 2 has trapezoidal grooves on both sides, and two sets of slide bars 44 are provided in the trapezoidal grooves. Rotating rollers 43 are slidably installed on the outer side of the slide bars 44. The movement of the target plate 3 is guided by the sliding of the rotating rollers 43 on the outer side of the slide bars 44, which improves the smoothness of the movement of the target plate 3. In addition, the four sets of rotating rollers 43 are symmetrically distributed to improve stability and better detect the accuracy of the target.

[0038] comprehensive Figure 1-2 As shown, an optoelectronic device 6 is installed above the head 1, and a reflector 5 is installed below the moving bracket 4. The optoelectronic device 6 is a photoelectric sensor. The optoelectronic device 6 emits photoelectric light, which is reflected back to the optoelectronic device 6 after illuminating the reflector 5. This enables precise control of the position of the target plate 3. The optoelectronic device 6 can detect the position and speed of the target plate 3 and then control the speed of the drive motor 7 to indirectly control the speed of the target plate 3. This better assists in simulating different speeds and improves the simulation quality and training effect of target shooting.

[0039] Beneficial effects:

[0040] 1. By cooperating with the four sets of symmetrical rotating rollers 43 in the trapezoidal grooves on both sides of the drive frame 2, the multi-directional force balance of the target plate 3 during movement is achieved. The trapezoidal cross-section design of the slide bar 44 increases the contact area of ​​the rotating rollers 43 and avoids rolling deviation. The symmetrical arrangement of the four sets of rollers forms a stable support structure, which effectively counteracts the lateral torque when the belt 10 is pulled. This design enables the target plate 3 to maintain a linear trajectory during high-speed movement, reduces positioning errors caused by vibration, and reduces wear on the rollers and slide bars, significantly improving the smoothness of movement. In addition, the trapezoidal groove structure can prevent foreign objects from entering the slide rail, ensuring the reliability of long-term use.

[0041] The photoelectric device 6 at the top of the 2-head 1 and the reflector 5 at the bottom of the moving support 4 form a closed-loop detection system. It achieves precise control by dynamically capturing the real-time position data of the target plate 3. When the drive motor 7 drives the moving support 4 through the belt 10, the photoelectric device 6 continuously emits / receives reflected light signals to accurately calculate the instantaneous displacement and speed of the target plate 3. This data is fed back to the motor control system in real time to dynamically adjust the output shaft speed, so that the target plate 3 can realize complex motion modes such as speed change and emergency stop according to the preset program. Compared with the traditional encoder detection scheme, this photoelectric system directly monitors the moving support 4 body, avoiding the accumulation of transmission chain errors. In particular, it can maintain positioning accuracy in high-speed reciprocating motion, significantly improving the realism of simulated shooting training.

[0042] The upper connecting block 42 of the 3-moving support 4 adopts a universal rotating structure, which allows the center of gravity of the target plate 3 of different shapes to be adaptively adjusted through the connecting block. When the target type is changed, the ball joint structure of the upper connecting block 42 automatically compensates for the positional deviation between the center of gravity of the target and the support point of the moving support 4, avoiding the problem of unilateral pressure on the rotating roller 43 caused by the asymmetry of the target body. At the same time, the lower fixed plate 41 and the belt 10 can be quickly disassembled and assembled through the modular connecting block. With the standardized interface design of the upper connecting block 42, the target plate 3 can be replaced with "one click", meeting the needs of continuous training of multiple subjects.

[0043] The closed-loop transmission system, consisting of the rack 9 inside the steering block 8 and the double sliding channel of the drive frame 2, achieves efficient power transmission through rack-belt composite transmission. The 90° steering design of the rack 9 at the steering block 8 converts the rotational motion of the drive motor 7 into bidirectional linear traction of the belt 10. Compared with the traditional single-sided traction method, this reduces the belt tensile stress. The double sliding channel structure provides full-range guidance for the rack 9, preventing tooth distortion during long-stroke motion. Especially under rapid acceleration conditions, the elastic characteristics of the belt 10 can buffer the start-stop impact, while the rigid transmission of the rack 9 ensures displacement accuracy. The two work together to give the system both high response speed and long service life.

[0044] In summary, the mobile target vehicle enhances its motion stability and prevents target plate 3 from shifting through the symmetrical guiding structure of slide bar 44 and four sets of rotating rollers 43; the optoelectronic device 6 and reflector 5 form a closed-loop detection system, which controls the drive motor 7 in real time to achieve precise displacement control; the rotation design of the upper connecting block 42 adapts to different target types for quick assembly and disassembly, ensuring center of gravity balance; the composite transmission system of rack 9 and belt 10 balances power response and durability. The coordinated optimization of all components significantly improves the target vehicle's motion accuracy, target changing efficiency, and the realism of training simulation.
