Description

Technical Field

[0001] This utility model relates to the field of catapult target machines, and further to a catapult target machine. Background Technology

[0002] Most existing catapult launchers use a direct compression spring on the target vehicle. The spring stores energy, and when the target vehicle is released, the compressed spring releases its elasticity and propels the target vehicle forward. At this point, the operator needs to apply a pushing force to the target vehicle at close range to compress the spring. Compressing the spring requires overcoming significant starting resistance, making the operation laborious. If misoperated, the energy stored in the spring may be released instantaneously, potentially causing the spring and target vehicle to collide with the operator, posing a significant safety risk. Furthermore, each use requires retrieving the target vehicle before the spring can be compressed again for re-launching, delaying the cycle and failing to meet the demands of modern tactical training for continuous rapid firing. Utility Model Content

[0003] To address the aforementioned technical problems, the purpose of this utility model is to provide a catapult target launcher. The launch base is releasably locked at the starting end of the launch track via a locking assembly. The target vehicle is launched along the axial direction of the launch track by the launch base. The launch base can be pulled again to prepare for launch without resetting the target vehicle, resulting in higher efficiency for continuous operation. Furthermore, the tension spring is located below the launch track, and the movable end of the tension spring is connected to the launch base via a traction rope. This physically isolates the energy storage and release process of the tension spring, effectively enhancing the safety of energy storage and release and reducing the risk of instantaneous energy release.

[0004] To achieve the above objectives, this utility model provides a catapult target machine, including a base and a target vehicle. The base is provided with a catapult track, a catapult seat, an elastic energy storage component, and a locking component. The catapult track has a starting end and an ending end. The catapult seat is slidably disposed on the catapult track and is releasably locked to the starting end of the catapult track by the locking component. The elastic energy storage component includes a tension spring and a traction rope. The tension spring is disposed below the catapult track and one end is fixedly connected to the base. One end of the traction rope is connected to the catapult seat, and the other end turns around the ending end of the catapult track and is connected to the movable end of the tension spring.

[0005] The target vehicle is positioned above the base and can be launched from the released launch platform along the axial direction of the launch track.

[0006] In some embodiments, the elastic energy storage component further includes a first fixed pulley, which is disposed at the end of the catapult track. One end of the traction rope is fixed to the catapult seat, and the other end is connected to the movable end of the tension spring after being turned by the first fixed pulley.

[0007] When the ejection seat is moved towards the starting end of the ejection track by an external force, the movable end of the tension spring is stretched towards the end of the ejection track by the traction rope to store energy.

[0008] When the locking assembly releases the ejection seat, the tension spring contracts toward the starting end of the ejection track and pulls the ejection seat toward the end of the ejection track at high speed through the traction rope, thereby launching the target vehicle.

[0009] In some embodiments, the tension spring extends along the axial direction of the launch track and one end is fixedly disposed below the starting end of the launch track;

[0010] The elastic energy storage component also includes a movable pulley and a second fixed pulley. The movable pulley is fixedly connected to the other end of the tension spring, and the second fixed pulley is fixedly disposed below the end of the catapult track. The traction rope is led out from the catapult seat, passes around the first fixed pulley, the second fixed pulley, and the movable pulley in sequence, and is then fixedly connected to the end of the catapult track or the fixed base of the second fixed pulley.

[0011] In some embodiments, a buffer base is provided at the end of the ejection track, and a buffer spring is coaxially mounted on the buffer base. The buffer spring extends along the axial direction of the ejection track, and the compressed end of the buffer spring is aligned with the end of the ejection seat near the end of the ejection track. The elastic deformation of the buffer spring absorbs the kinetic energy of the ejection seat, thereby realizing the controllable deceleration and braking of the ejection seat.

[0012] In some embodiments, the locking assembly includes an electrically controlled lock box and a locking structure. The electrically controlled lock box is located directly above the starting end of the ejection track, and the electrically controlled lock box is also provided with a charging interface and a power switch.

[0013] The locking structure is located at one end of the ejection seat near the starting end of the ejection track, and the locking structure is adapted to form a releasable locking engagement with the electronically controlled lock box.

[0014] In some embodiments, the top of the ejection seat is also provided with a transmission rod, which is vertically arranged above the ejection seat and can drive the ejection seat to move; the transmission rod is also adapted to abut against the target vehicle and push the target vehicle to move.

[0015] In some embodiments, the bottom of the base is further provided with a plurality of spaced anti-slip pads, which extend along the axial direction of the launch track.

[0016] In some embodiments, the base is further provided with a hand handle, which is located at the starting end of the catapult track and is adapted to pull the base.

[0017] In some embodiments, the target vehicle is provided with at least two sets of positioning track wheels at its bottom, and slide rails are symmetrically arranged on both sides of the catapult track, with the extension direction of the slide rails being parallel to the axial direction of the catapult track.

[0018] The positioning track wheel is adapted to be slidably installed in the slide rail, so that the target vehicle is adapted to be linearly ejected along the axial direction of the slide rail.

[0019] In some embodiments, the target vehicle is also provided with several wheels at its bottom;

[0020] The top of the target vehicle is also equipped with several sockets, which are suitable for placing the target rod.

[0021] Compared with the prior art, the catapult target machine provided by this utility model has at least one of the following beneficial effects:

[0022] 1. The ejector base can be released and locked at the starting end of the ejection track via a locking assembly. The target vehicle is launched along the axis of the ejection track by the ejector base. The ejector base can be pulled again to prepare for ejection without resetting the target vehicle, which improves the efficiency of continuous operation. Moreover, the tension spring is set below the ejection track, and the movable end of the tension spring is connected to the ejector base via a traction rope. This physically isolates the energy storage and release process of the tension spring, effectively enhancing the safety of energy storage and release and reducing the risk of instantaneous energy release.

[0023] 2. The first fixed pulley is installed at the end of the catapult track to change the direction of force on the traction rope, so that the traction rope can smoothly connect the tension spring and the catapult seat. The friction loss of the traction rope during the turning process is minimal, which effectively improves the force transmission efficiency.

[0024] 3. The traction rope is led out from the launcher, passes through the first fixed pulley, the second fixed pulley and the movable pulley in sequence, and is then fixedly connected to the end of the launcher track or the fixed base of the second fixed pulley. This can effectively reduce the required traction force, increase the force transmission distance, and thus improve energy storage efficiency. It can also reduce the deformation length of the tension spring, thereby reducing the stress level of the tension spring and effectively extending the service life of the tension spring.

[0025] 4. The elastic deformation of the buffer spring absorbs the kinetic energy of the ejection seat, braking the ejection seat and effectively controlling the deceleration process of the ejection seat; the anti-slip pad not only significantly improves the grip of the base, but also effectively reduces the displacement that may be caused by vibration and impact during the ejection process, ensuring the accuracy and safety of the ejection process.

[0026] 5. The electronically controlled lock box is installed directly above the starting end of the catapult track, and the locking structure is installed at the end of the catapult seat near the starting end of the catapult track. The electronically controlled lock box provides precise locking to the locking structure. The transmission rod not only serves as a power transmission device to drive the movement of the catapult seat, but also directly participates in the pushing process of the target vehicle, ensuring the accurate execution of the catapult action.

[0038] refer to Figure 1 and Figure 2 This utility model provides a catapult target machine, including a base 1 and a target vehicle 2. The base 1 is provided with a catapult track 11, a catapult seat 12, an elastic energy storage component 13, and a locking component 14. The catapult track 11 has a starting end and an ending end. The catapult seat 12 is slidably disposed on the catapult track 11 and is releasably locked to the starting end of the catapult track 11 by the locking component 14. The elastic energy storage component 13 includes a tension spring 131 and a traction rope 132. The tension spring 131 is disposed below the catapult track 11 and one end is fixedly connected to the base 1. One end of the traction rope 132 is connected to the catapult seat 12, and the other end is turned around the ending end of the catapult track 11 and connected to the movable end of the tension spring 131. The target vehicle 2 is disposed above the base 1 and can be launched out along the axial direction of the catapult track 11 by the released catapult seat 12.

[0039] In this embodiment, the ejector seat 12 is releasably locked to the starting end of the ejection track 11 by the locking assembly 14. The target vehicle 2 is ejected along the axial direction of the ejection track 11 by the ejector seat 12. The ejector seat can be pulled again to complete the ejection preparation without resetting the target vehicle 2, which improves the efficiency of continuous operation. Moreover, the tension spring 131 is set below the ejection track 11. The movable end of the tension spring 131 is connected to the ejector seat 12 via the traction rope 132, which physically isolates the energy storage and release process of the tension spring 131, effectively enhancing the safety of energy storage and release and reducing the risk of instantaneous energy release.

[0040] Specifically, the launch track 11 is elongated with clearly defined starting and ending points, providing a stable path for the sliding of the launch base 12. The launch base 12 can be flexibly slidably mounted on the launch track 11, and with the help of the locking assembly 14, it can reliably lock and instantly release at the starting end of the launch track 11, providing a solid guarantee for the accurate triggering of the launch action. In actual operation, there is no need to reset the target vehicle 2 or pull the launch base again, which can quickly complete the preparation work for the next launch, greatly improving the efficiency of continuous operation, making the training process smoother and more compact, and effectively improving the training quality.

[0041] The elastic energy storage component 13 is the key component of the entire catapult target machine. It consists of a tension spring 131 and a traction rope 132. The traction rope 132 is made of high-strength synthetic fiber material or steel wire rope, which has the advantages of being lightweight, high-strength, and wear-resistant, and can withstand large tensile forces without easily breaking. The tension spring 131 is arranged parallel to the catapult track 11 directly below it. This not only makes full use of the space below the catapult track 11, but also effectively avoids interference with other components. One end of the tension spring 131 is firmly fixed to the base 1, ensuring a stable support point during energy storage. One end of the traction rope 132 is tightly connected to the catapult seat 12, and the other end turns around the end of the catapult track 11 and connects to the movable end of the tension spring 131, forming a stable power transmission system. In actual operation, the tension spring 131 is located on the upper surface of the base 1 and below the catapult track 11, and the energy storage and release processes of the tension spring 131 are physically isolated. During the ejection process, the traction rope 132 serves as an intermediate medium, connecting the movable end of the tension spring 131 to the ejection seat 12. This effectively avoids potential safety hazards caused by the tension spring 131 directly contacting the ejection seat 12 or other components when releasing energy, thereby significantly enhancing the safety of the energy storage and release process, effectively reducing the risks caused by the instantaneous and disorderly release of energy, and providing operators with a more reliable operating environment.

[0042] The target vehicle 2 is positioned above the base 1, its position precisely corresponding to the axis of the ejection track 11. When the locking assembly 14 releases the lock on the ejection seat 12, the elastic potential energy of the tension spring 131 is rapidly converted into kinetic energy, causing the ejection seat 12 to slide at high speed along the axis of the ejection track 11, thereby driving the target vehicle 2 to be ejected forward at extremely high speed, providing a realistic and dynamic target simulation for shooting training.

[0043] Preferably, the elastic energy storage component 13 further includes a first fixed pulley 133, which is disposed at the end of the ejection track 11. One end of the traction rope 132 is fixed to the ejection seat 12, and the other end is connected to the movable end of the tension spring 131 after being turned by the first fixed pulley 133. When the ejection seat 12 is moved towards the starting end of the ejection track 11 by an external force, the movable end of the tension spring 131 is stretched towards the end of the ejection track 11 by the traction rope 132 to store energy. When the locking component 14 releases the ejection seat 12, the tension spring 131 contracts towards the starting end of the ejection track 11 and pulls the ejection seat 12 towards the end of the ejection track 11 at high speed through the traction rope 132, thereby realizing the ejection of the target vehicle 2.

[0044] In this embodiment, the first fixed pulley 133 is installed at the end of the catapult track 11 to change the force direction of the traction rope 132, so that the traction rope 132 can smoothly connect the tension spring 131 and the catapult seat 12. The friction loss of the traction rope 132 during the turning process is minimal, which effectively improves the force transmission efficiency.

[0045] Specifically, the traction rope 132 extends along the axis of the launch track and is fixed at one end to the launch seat 12 with fasteners to ensure that it will not detach during launch. When energy storage is required for the launch device, the operator pushes the launch seat 12 smoothly towards the starting end along the launch track 11 using external force. As the launch seat 12 moves, the traction rope 132 is gradually tightened, and the other end, after being turned by the first fixed pulley 133, drives the movable end of the tension spring 131 to extend towards the end of the launch track 11, causing the tension spring 131 to undergo elastic deformation, thereby achieving energy storage. During this process, the energy stored in the tension spring 131 is proportional to its extension. The operator can control the moving distance of the launch seat 12 according to actual needs, thereby adjusting the amount of energy stored to meet the requirements of different launch intensities.

[0046] When the locking assembly 14 receives the ejection command and quickly releases the lock on the ejection seat 12, the tension spring 131, under its own elastic force, rapidly contracts and resets towards the starting end of the ejection track 11. This contraction action is transmitted to the ejection seat 12 through the traction rope 132, and the resulting strong tension causes the ejection seat 12 to instantly gain a large acceleration, moving at high speed along the axis of the ejection track 11 towards the end of the ejection track 11. During the high-speed sliding process, the kinetic energy of the ejection seat 12 is rapidly transferred to the target vehicle 2, driving the target vehicle 2 forward at high speed, thereby achieving rapid ejection of the target vehicle 2. The entire ejection process is smooth and rapid, with efficient energy transfer, ensuring that the target vehicle 2 can complete the ejection action with precise speed and trajectory, providing a realistic and dynamic target simulation for shooting training.

[0047] It is worth noting that this embodiment optimizes the force transmission path through the steering action of the first fixed pulley 133, making the operation of the elastic energy storage component 13 more stable and reliable. Simultaneously, it is simple to operate and easy to adjust, allowing for flexible adjustment of the energy storage capacity according to different training needs, greatly improving the practicality and adaptability of the catapult target machine. In a modified embodiment, a steering groove can also be provided at the end of the catapult track 11, and the traction rope 132 connects to the tension spring 131 after turning through the steering groove. The steering groove is arc-shaped to ensure smooth turning of the traction rope 132 within the groove, reducing energy loss and rope wear, which is also within the scope of protection of this application.

[0048] Furthermore, one end of the tension spring 131 is fixedly disposed below the starting end of the catapult track 11; the elastic energy storage component 13 also includes a movable pulley 134 and a second fixed pulley 135. The movable pulley 134 is fixedly connected to the other end of the tension spring 131, and the second fixed pulley 135 is fixedly disposed below the end of the catapult track 11. The traction rope 132 is led out from the catapult seat 12, passes through the first fixed pulley 133, the second fixed pulley 135 and the movable pulley 134 in sequence, and is then fixedly connected to the end of the catapult track 11 or the fixed base 136 of the second fixed pulley 135.

[0049] In this embodiment, the traction rope 132 is led out from the ejector seat 12, passes through the first fixed pulley 133, the second fixed pulley 135 and the movable pulley 134 in sequence, and is then fixedly connected to the end of the ejection track 11 or the fixed base 136 of the second fixed pulley 135. This can effectively reduce the required traction force, increase the force transmission distance, and thus improve the energy storage efficiency. Moreover, it can also reduce the deformation length of the tension spring 131, thereby reducing the stress level of the tension spring 131 and effectively extending the service life of the tension spring 131.

[0050] Specifically, one end of the tension spring 131 is fixedly installed below the starting end of the launch track 11, ensuring that the tension spring 131 has a stable support point during energy storage and release, and also facilitating coordination with other components. Furthermore, the fixed position of the tension spring 131 is furthest from the end of the launch track 11, providing greater elastic force. The movable pulley 134 is fixedly connected to the other end of the tension spring 131, while the second fixed pulley 135 is fixedly installed below the end of the launch track 11. The traction rope 132 is led out from the launch base 12, passes sequentially around the first fixed pulley 133, the second fixed pulley 135, and the movable pulley 134, and is then fixedly connected to the end of the launch track 11 or the fixed base 136 of the second fixed pulley 135, ensuring that the traction rope 132 will not shift or loosen during launch. The first fixed pulley 133, the second fixed pulley 135, and the movable pulley 134 are all mounted on their fixed bases 136. The fixing method of the pulleys is a conventional structure, which will not be described in detail here.

[0051] During the energy storage process, when the ejector seat 12 is moved towards the starting end of the ejection track 11 by an external force, the traction rope 132 is pulled, passing sequentially around the first fixed pulley 133, the second fixed pulley 135, and the movable pulley 134, causing the movable end of the tension spring 131 to extend towards the end of the ejection track 11, thus achieving elastic energy storage. At this time, the movable pulley 134 moves towards the end of the ejection track 11 as the tension spring 131 is stretched, allowing the tension spring 131 to store more elastic potential energy.

[0052] When the locking assembly 14 releases the ejector seat 12, the tension spring 131 rapidly contracts under the drive of elastic potential energy. Through the cooperation of the traction rope 132 and the movable pulley 134, a strong pulling force is generated, causing the ejector seat 12 to move at high speed along the axis of the ejection track 11 towards the end of the ejection track 11. This not only improves the efficiency of force transmission but also makes the movement of the ejector seat 12 more stable, ensuring that the target vehicle 2 can complete the ejection with precise speed and trajectory.

[0053] Furthermore, the traction rope 132 is fixed to the end of the launch track 11 or the fixed base 136 of the second fixed pulley 135 after wrapping once between the second fixed pulley 135 and the movable pulley 134. At this time, the moving distance of the launch seat 12 is twice the extension length of the tension spring 131, which significantly reduces the deformation length of the tension spring 131 and thus reduces the stress level of the tension spring 131. In particular, during the process of the launch seat 12 moving from the end of the launch track 11 to the beginning of the launch track 11, the launch seat 12 needs to move the entire length of the launch track 11. If the tension spring 131 also deforms the entire length of the launch track, the tension spring 131 is very easy to be damaged. When storing energy, the operator pushes the launch seat 12 to move a certain distance. Through the force transmission and direction conversion of the first fixed pulley 133, the second fixed pulley 135 and the movable pulley 134, the distance that the traction rope 132 drives the movable end of the tension spring 131 to move is only half the moving distance of the launch seat 12. In this way, while achieving the same energy storage effect, the extension length of the tension spring 131 is significantly reduced, lowering the stress caused by excessive stretching or compression and effectively extending its service life. This not only improves energy storage efficiency but also enhances the stability and reliability of the entire system. During launch, the tension spring 131 can release energy more smoothly, ensuring more precise and rapid movement of the launch platform 12 and the target vehicle 2. Simultaneously, reducing the deformation length of the tension spring 131 lowers the risk of breakage or failure, improving the safety performance of the launch system.

[0054] It is worth noting that the number of turns of the traction rope 132 between the second fixed pulley 135 and the movable pulley 134 is not further limited in this application. Through the second fixed pulley 135 and the movable pulley 134, the ratio of the moving distance of the ejector seat 12 to the extension length of the tension spring 131 is realized, making the entire elastic energy storage component 13 more efficient, stable and safe in the process of energy storage and release.

[0055] Furthermore, a buffer base 111 is provided at the end of the catapult track 11. A buffer spring 112 is coaxially mounted on the buffer base 111. The buffer spring 112 extends along the axial direction of the catapult track 11. The compressed end of the buffer spring 112 is aligned with the end of the catapult seat 12 near the end of the catapult track 11. The elastic deformation of the buffer spring 112 absorbs the kinetic energy of the catapult seat 12, thereby realizing the controllable deceleration and braking of the catapult seat 12.

[0056] In this embodiment, the elastic deformation of the buffer spring 112 absorbs the kinetic energy of the ejector seat 12, thereby braking the ejector seat 12 and effectively controlling the deceleration process of the ejector seat 12.

[0057] Specifically, a buffer base 111 is provided at the end of the ejection track 11, and a buffer spring 112 is coaxially mounted on the buffer base 111. The axis of the buffer spring 112 coincides with the axis of the ejection track 11 to ensure that the direction of force transmission is consistent with the direction of movement of the ejection seat 12, avoiding deviation or jamming. The buffer spring 112 extends along the axis of the ejection track 11, and its compressed end is precisely aligned with the end of the ejection seat 12 near the end of the ejection track 11. When the ejection seat 12 moves at high speed towards the end of the ejection track 11 under the action of the tension spring 131, its front end gradually approaches the compressed end of the buffer spring 112. At the instant the ejection seat 12 contacts the buffer spring 112, the buffer spring 112 begins to undergo elastic deformation, gradually converting the kinetic energy of the ejection seat 12 into elastic potential energy. This process is achieved through the compression deformation of the buffer spring 112, effectively absorbing the kinetic energy of the ejection seat 12, causing the movement speed of the ejection seat 12 to gradually decrease until it comes to a complete stop.

[0058] It is worth noting that in this embodiment, the elastic deformation of the buffer spring 112 effectively absorbs the kinetic energy of the ejection seat 12, achieving controllable deceleration and braking of the ejection seat 12, and also improving the safety and reliability of the ejection system. During the ejection process, the movement of the ejection seat 12 is more stable, avoiding equipment damage or personal injury that may be caused by excessive instantaneous impact force. In a modified embodiment, other elastic materials may also be provided at the end of the ejection track 11, and the ejection seat 12 may be braked by the deformation of the elastic materials themselves. This is something that those skilled in the art can easily conceive of, and all are within the scope of protection of this application.

[0059] Further, refer to Figure 3The locking assembly 14 includes an electronically controlled lock box 141 and a locking structure 142. The electronically controlled lock box 141 is located directly above the starting end of the ejection track 11. The electronically controlled lock box 141 is also provided with a charging interface 143 and a power switch 144. The locking structure 142 is located at one end of the ejection seat 12 near the starting end of the ejection track 11. The locking structure 142 is adapted to form a releasable locking engagement with the electronically controlled lock box 141.

[0060] In this embodiment, the electronically controlled lock box 141 is installed directly above the starting end of the ejection track 11, and the locking structure 142 is installed at one end of the ejection seat 12 near the starting end of the ejection track 11. The electronically controlled lock box 141 precisely locks the locking structure 142.

[0061] Specifically, the locking structure 142 and the electrically controlled lock box 141 are locked together by a latch driven by an electromagnet. When the electrically controlled lock box 141 receives an ejection command, the electromagnet is energized to generate a magnetic field, driving the latch to retract and unlocking the ejection seat 12. The locking function of the locking assembly 14 is implemented in a manner that is prior art, and its specific components will not be further described here. The charging interface 143 is a universal interface that supports fast charging.

[0062] Furthermore, the top of the ejection seat 12 is also provided with a transmission rod 121, which is vertically arranged above the ejection seat 12. The transmission rod 121 can drive the ejection seat 12 to move; the transmission rod 121 is also adapted to abut against the target vehicle 2 and push the target vehicle 2 to move.

[0063] In this embodiment, the transmission rod 121 not only serves as a power transmission device for driving the ejection seat 12 to move, but also directly participates in the pushing process of the target vehicle 2, ensuring the accurate execution of the ejection action.

[0064] Specifically, the transmission rod 121 is vertically positioned above the ejection seat 12. Through a secure connection with the ejection seat 12, it ensures the efficient transfer of kinetic energy from the ejection seat 12 to the target vehicle 2 during ejection. When the ejection system is in an energy storage state, it is connected to an external drive device (such as an electric motor or manual lever) to transmit driving force to the ejection seat 12, causing it to move along the ejection track 11 towards the starting end. During this process, the transmission rod 121 not only acts as a force transmission medium but also, through its vertical position relative to the ejection seat 12, ensures the ejection seat 12 remains stable during movement, preventing deviation or swaying due to lateral forces. During ejection, when the locking assembly 14 releases the ejection seat 12, the tension spring 131 rapidly contracts, and through the cooperation of the traction rope 132 and the first fixed pulley 133, pushes the ejection seat 12 at high speed along the axial direction of the ejection track 11 towards the end of the ejection seat 12. The transmission rod 121, as part of the ejector base 12, moves synchronously at high speed and contacts the target vehicle 2, efficiently transferring the kinetic energy of the ejector base 12 to the target vehicle 2, driving the target vehicle 2 to move forward at extremely high speed.

[0065] It is worth noting that the transmission rod 121 can also be quickly adjusted according to different target vehicle types and sizes. It can also be in the shape of a transmission block, etc., which is not further limited here. By replacing the transmission rod 121 with different specifications or adjusting its height, various ejection requirements of the target vehicle 2 can be met, significantly improving the applicability and flexibility of the ejection target machine. The transmission rod 121 can also integrate various sensors and monitoring devices. For example, a pressure sensor can monitor the thrust exerted by the transmission rod 121 when pushing the target vehicle 2 in real time, ensuring that the thrust is within a safe range and avoiding equipment damage due to overload. A position sensor can accurately monitor the movement position of the transmission rod 121, ensuring that the movement trajectory of the ejection seat 12 and the target vehicle 2 meets the requirements.

[0066] Furthermore, the bottom of the base 1 is also provided with several anti-slip pads 15 spaced apart, which extend along the axial direction of the catapult track 11.

[0067] In this embodiment, the anti-slip pad 15 not only significantly improves the grip of the base 1, but also effectively reduces the displacement that may be caused by vibration and impact during the ejection process, ensuring the accuracy and safety of the ejection process.

[0068] Specifically, the anti-slip pad 15 is made of high-strength, wear-resistant rubber material, possessing excellent anti-slip performance and weather resistance. The anti-slip pad 15 extends along the axial direction of the catapult track 11, applying frictional force to the base 1 along the axial direction of the catapult track 11. This ensures that the base 1 remains stable and does not shift or wobble during the high-speed movement of the catapult seat 12 and the launch of the target vehicle 2. Furthermore, the anti-slip pads 15 are evenly distributed at intervals on the bottom of the base 1, ensuring that the weight and impact force are evenly distributed during launch, preventing slippage or instability caused by excessive local pressure. The spacing direction of the anti-slip pads 15 can be along or perpendicular to the axial direction of the catapult track 11; this application does not further limit this. Moreover, the anti-slip pad 15 should also possess a certain degree of elasticity, effectively absorbing vibrations and impacts from uneven ground, protecting the precision components inside the base 1 and extending the service life of the anti-slip pad 15. The installation method of the anti-slip mat 15 will not be described in detail here. It can be firmly fixed to the bottom of the base 1 with bolts and self-locking nuts to ensure that it will not loosen or fall off during long-term use and high-intensity ejection.

[0069] It is worth noting that the surface of each anti-slip mat 15 may also be provided with fine patterns and grooves. These textures can effectively increase the friction with the ground and prevent the base 1 from sliding on wet or slippery surfaces. At the same time, in order to further increase the anti-slip performance of the anti-slip mat 15, several suction cup structures or other fixing structures may be provided on the bottom of the anti-slip mat 15 to further enhance its adhesion to the ground.

[0070] Preferably, the base 1 is also provided with a hand handle 16, which is located at the starting end of the catapult track 11 and is suitable for pulling the base 1.

[0071] Furthermore, the target vehicle 2 is provided with at least two sets of positioning track wheels 21 at its bottom, and slide rails 113 are symmetrically arranged on both sides of the catapult track 11. The extension direction of the slide rails 113 is parallel to the axial direction of the catapult track 11. The positioning track wheels 21 are adapted to be slidably installed in the slide rails 113, so that the target vehicle 2 is adapted to be linearly ejected along the axial direction of the slide rails 113.

[0072] In this embodiment, the positioning track wheel 21 cooperates with the slide rails 113 symmetrically arranged on both sides of the catapult track 11, and the extension direction of the slide rails 113 is parallel to the axial direction of the catapult track 11, which ensures the stability and accuracy of the target vehicle 2 during the catapult process.

[0073] Specifically, the positioning track wheel 21 is adapted to slide within the slide rail 113, allowing the target vehicle 2 to be linearly ejected along the axis of the slide rail 113. This enables the target vehicle 2 to move along a predetermined trajectory at extremely high speed, ensuring the accuracy and reliability of shooting training. During ejection, the positioning track wheel 21 rolls within the slide rail 113, transforming the movement of the target vehicle 2 into smooth linear motion. This not only ensures the accuracy of the target vehicle 2's trajectory but also effectively reduces swaying and deviation during movement. The bottom of the target vehicle 2 is also equipped with several traveling wheels 22, which allow the target vehicle 2 to move on the ground. The top of the target vehicle 2 is also equipped with several sockets 23, which are suitable for placing target poles. The target poles are equipped with the target and other shooting components.

[0074] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this utility model. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
