[0002] Target launchers are an important training tool, simulating real battlefield environments and conditions to train soldiers' shooting skills and tactical response capabilities. They can also be used to test and evaluate the performance and accuracy of weapon systems.

[0003] Target ammunition is a type of training ammunition that simulates live ammunition and is commonly used in military exercises and shooting training.

[0004] A target launch vehicle typically includes a vehicle chassis, launching device, control system, and drive system. The vehicle is equipped with a specialized launching device for securing and launching target missiles. The mechanism that secures the target missile to the launching device is usually called the target missile securing and locking device.

[0005] Existing target missile launchers typically use tensioners or ropes to secure the target missiles to the launching device, but this method of securing them has the following problems:

[0006] (1) If the tensioner or rope is not securely fixed, it may loosen due to vibration during transportation, posing a risk that the target projectile may detach from the launching device.

[0007] (2) When using tensioners or ropes to fix the target projectile, manual fixing and loosening are required, resulting in low automation.

[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, not all, of the embodiments of the present invention. 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 Figure 1-6As shown, this application provides an automatic fixing and locking device for transporting target projectiles, including: a rotary motor 1, a locking and fixing mechanism 2, and a power transmission device 3. The rotary motor 1 is mounted on the erecting support of the launching device. The locking and fixing mechanism 2 is mounted on the erecting support of the launching device and is rotatably connected to the erecting support. The locking and fixing mechanism 2 includes at least: a cylinder mounting plate 20, a fixing plate 21, a cylinder 22, a cylinder connecting plate 23, a first opening and closing action plate 24, a first contact limiting plate 25, a second opening and closing action plate 26, a second contact limiting plate 27, a first transmission connecting plate 28, a second transmission connecting plate 29, and a power transmission wheel 30. One end of the cylinder mounting plate 20 is fixedly connected to the middle of the fixing plate 21; the cylinder 22 is disposed at the other end of the cylinder mounting plate 23, and the front end of the cylinder piston rod 221 of the cylinder 22 is detachably connected to the cylinder connecting plate 23, which is located between the cylinder 22 and the fixing plate 21; one end of the first opening and closing action plate 24 is rotatably connected to one end of the fixing plate 21, and the other end of the first opening and closing action plate 24 is connected to the first contact limiting plate 25; one end of the second opening and closing action plate 26 is rotatably connected to the other end of the fixing plate 21, and the other end of the second opening and closing action plate 26 is connected to the second contact limiting plate 27; one end of the first transmission connecting plate 28 is rotatably connected to the cylinder connecting plate 23, and the other end of the first transmission connecting plate 28 is connected to the first opening and closing action plate 25. One end of the actuating plate 24 is rotatably connected to the fixed plate 21. After connection, the first transmission connecting plate 28 is in an inclined state. One end of the second transmission connecting plate 29 is rotatably connected to the cylinder connecting plate 23, and the other end of the second transmission connecting plate 29 is rotatably connected to the end of the second opening and closing actuating plate 26 connected to the fixed plate 21. After connection, the second transmission connecting plate 29 is in an inclined state. The extension and retraction of the cylinder piston rod 221 drives the cylinder connecting plate 23 to move vertically along the cylinder mounting plate 20. The cylinder connecting plate 23 drives the first transmission connecting plate 28 and the second transmission connecting plate 29 to move. Then, the first transmission connecting plate 28 and the second transmission connecting plate 29 respectively drive the first opening and closing actuating plate 24 and the second opening and closing actuating plate 26 to open and close laterally. The power transmission wheel 30 is set on the fixed plate 21 and is connected to the rotary motor 1 through the power transmission device 3. The rotary motor 1 drives the power transmission device 3 to rotate, and then the power transmission device 3 drives the fixed plate 21 to rotate vertically along the erecting support. When locked, the first fitting limiting plate 25 fits against one side of the target project placed on the erecting support, and the second fitting limiting plate 27 fits against the other side of the target project placed on the erecting support.

[0035] Specifically, the number of automatic locking devices for target transport installed on the launching device depends on the actual situation. This application preferably uses two automatic locking devices for target transport per launching device. During target storage or transport, the target is fixed to the launching device via guide rails and secured by the locking mechanism of the automatic locking devices, thus restricting the target's movement along the launch direction and its movement perpendicular to the left and right directions; the guide rails also restrict the target's free movement in other directions. Before launch, the automatic locking devices are unlocked, allowing the locking mechanism to release the target and rotate to its vertically downward limit position, thereby avoiding the target's launch trajectory.

[0036] Furthermore, it also includes: mechanism mounting bracket 4, the locking and fixing mechanism 2 is connected to the erecting bracket of the launching device through the mechanism mounting bracket 4, and the locking and fixing mechanism 2 and the mechanism mounting bracket 4 are rotatably connected.

[0037] Furthermore, it also includes: a motor mounting bracket 5, through which the rotary motor 1 is mounted on the erecting bracket of the launching device.

[0038] Furthermore, such as Figure 1-5 As shown, it also includes an upper baffle 6 and a lower baffle 7. The upper baffle 6 is fixed to the erecting support of the launching device and is located between the locking and fixing mechanism 2 and the rotary motor 1. When the power transmission device 3 drives the fixing plate 21 to rotate vertically along the erecting support, the upper baffle 6 limits the vertical upward limit position of the locking and fixing mechanism 2 when it rotates upward to fix the target projectile. When the locking and fixing mechanism 2 is at the vertical upward limit position, the first opening and closing action plate 24 and the second opening and closing action plate 26 are both in contact with the upper baffle 6. The lower baffle 7 is fixed to the erecting support of the launching device and is located on the side of the locking and fixing mechanism 2 away from the rotary motor 1. When the power transmission device 3 drives the fixing plate 21 to rotate vertically along the erecting support, the lower baffle 7 limits the vertical downward limit position of the locking and fixing mechanism 2 when it rotates downward away from the target projectile. When the locking and fixing mechanism 2 is at the vertical downward limit position, the first opening and closing action plate 24 and the second opening and closing action plate 26 are both in contact with the lower baffle 7.

[0039] Specifically, an automatic locking device for transporting target projectiles is equipped with an upper baffle 6 and a lower baffle 7. The upper baffle 6 prevents the locking mechanism 2 from over-rotating or under-rotating, ensuring accurate engagement between the locking mechanism 2 and the target projectile. The lower baffle 7 prevents the locking mechanism 2 from over-rotating or under-rotating, ensuring that the locking mechanism 2 does not interfere with the target projectile's launch trajectory.

[0040] Furthermore, it also includes: an upper positioning sensor and a lower positioning sensor. The upper positioning sensor is set on the erecting support of the transmitting device and is close to the upper baffle 6; the lower positioning sensor is set on the erecting support of the transmitting device and is close to the lower baffle 7.

[0043] Specifically, the cylinder connecting plate 23 can be an integral structure or a separate structure; in this application, an integral structure is preferred. The cylinder connecting plate 23 is used to transmit the extension and retraction motion of the cylinder piston rod 221 to the first transmission connecting plate 28 and the second transmission connecting plate 29. There is a gap between the cylinder connecting plate 23 and the cylinder mounting plate 20, but they do not contact each other and can move relative to each other.

[0044] Furthermore, a piston rod through hole is provided on the connecting cross plate. The front end of the cylinder piston rod 221 is provided with a threaded structure; the front end of the cylinder piston rod 221 passes through the piston rod through hole and is connected to the nut 222.

The rotary motor 1 drives the rotating sprocket to rotate, the rotating sprocket drives the chain to move, the chain drives the transmission sprocket to rotate, and the transmission sprocket drives the fixed plate 21 to rotate vertically along the erecting support.

[0047] Specifically, the rotating sprocket on the shaft of the rotary motor 1 is adapted to the power transmission device; the power transmission wheel is adapted to the power transmission device 3. The power transmission device 3 is a chain, but not limited to a chain, it can also be a belt or gears, and in this application, a chain is preferred.

[0048] Furthermore, the side of the first bonding limiting plate 25 that contacts the target projectile is provided with antistatic cloth or felt; the side of the second bonding limiting plate 27 that contacts the target projectile is provided with antistatic cloth or felt, which can prevent the first bonding limiting plate 25 and the second bonding limiting plate 27 from scratching the target projectile when they come into contact with it.

[0049] Furthermore, the shapes of the first fitting limiting plate 25 and the second fitting limiting plate 27 are both set according to the shape of the target projectile's usage position, and are adapted to the shape of the target projectile's usage position, so as to better fit the target projectile and fix the target projectile without causing damage to the target projectile. For example, when used at the very front of the target projectile, the shapes of the first fitting limiting plate 25 and the second fitting limiting plate 27 are similar to the target projectile head; when used in the middle of the target projectile, the shapes of the first fitting limiting plate 25 and the second fitting limiting plate 27 can be in the form of a quarter circle.

[0050] Furthermore, the first opening / closing action plate 24 is connected to the fixed plate via a pin, but is not limited to a pin; in this application, a pin is preferred. The second opening / closing action plate 26 is connected to the fixed plate via a pin, but is not limited to a pin; in this application, a pin is preferred.

[0051] Specifically, the pin connection is a clearance fit, allowing for relative movement.

[0053] Furthermore, the other end of the second opening and closing action plate 26 is welded or threaded to the second contact limiting plate 27, but is not limited to welding or threading.

[0054] Furthermore, one end of the cylinder mounting plate 20 is welded or threaded to the middle of the fixing plate 21, but is not limited to welding or threading.

[0055] Furthermore, the rotary motor 1 has a built-in reducer for driving the locking and fixing mechanism 2.

[0056] Furthermore, under the drive of the rotary motor 1, the vertical rotation angle of the locking and fixing mechanism 2 is 90 degrees, but not limited to 90 degrees. In this application, 90 degrees is preferred.

[0057] Furthermore, the rotary motor 1 uses an electric motor as the drive source, but it is not limited to an electric motor. It can also use a hydraulic motor or a pneumatic motor as the drive source. In this application, an electric motor is preferred.
