[0002] Target drones are widely used in modern shooting training due to their advantages such as mobility, low operating costs, and reusability. With the continuous development of technology, target drone firing methods have become increasingly diverse.

[0003] A certain type of target drone requires launch from a launch pad and takes off with the thrust of a booster. After takeoff, the booster automatically detaches. To achieve automatic booster detachment, the booster and the target drone cannot be connected and restrained in the X-axis direction; that is, the booster cannot be connected and restrained with the target drone along its flight direction. Therefore, the booster cannot be omnidirectionally fixed before launch, making accurate launch impossible. Summary of the Invention

[0038] like Figure 1-6As shown, in one embodiment of the present invention, a target drone launching fixing device is provided. The fixing device includes a launch frame assembly 40, a tail support assembly 10, a clamping assembly 20, and an anti-rebound assembly 30. The launch frame assembly 40 includes a base 43, a first support part 41, and a second support part 42. The first support part 41 and the second support part 42 are fixedly disposed on the base 43 at intervals. The launch frame assembly 40 is fixedly positioned relative to the target drone booster positioning surface 200, and the head of the booster 100 abuts against the target drone booster positioning surface 200. The tail support assembly 10 includes an arc-shaped tail support ring 12, a cross-shaped rotating frame 11, a Y-shaped frame 13, a longitudinal fine-tuning part 14, a first torsion spring 15a, a second torsion spring 15b, a first sliding part, and a second sliding part. The cross-shaped frame 11 includes a first lateral fine-tuning part 17a and a second lateral fine-tuning part 17b, wherein: the cross-shaped frame 11 includes a first shaft 11a, a second shaft 11b, a third shaft 11c, and a fourth shaft 11d connected in sequence, with an included angle of 90° between any adjacent shafts; the tail of the booster 100 is disposed on the tail support ring 12, and the two ends of the tail support ring 12 are rotatably connected to the two sides of the forked portion 13a of the Y-shaped frame 13 to adapt to the angle of the target booster 100; the vertical portion 13b of the Y-shaped frame 13 is movably disposed within the first shaft 11a along the axial direction of the first shaft 11a and cannot rotate around the first shaft 11a; the longitudinal fine-tuning part 14 is rotatably disposed at the free end of the first shaft 11a, and the longitudinal fine-tuning part 14 is connected to the Y-shaped frame 13. The vertical part 13b of the frame 13 cooperates to realize the reciprocating movement of the Y-shaped frame 13 along the axial direction of the first shaft 11a; the second shaft 11b and the fourth shaft 11d are rotatably connected to the first sliding part and the second sliding part, respectively; the first torsion spring 15a is sleeved on the second shaft 11b, one end of which is fixedly connected to the second shaft 11b and the other end of which is fixedly connected to the first sliding part; the second torsion spring 15b is sleeved on the fourth shaft 11d, one end of which is fixedly connected to the fourth shaft 11d and the other end of which is fixedly connected to the second sliding part; the first sliding part is movably disposed in the first support part 41, the second sliding part is movably disposed in the second support part 42, and the first lateral fine-tuning part 17a is disposed on the first support part 41. The second lateral fine-tuning part 17b is disposed on the second support part 42. The first lateral fine-tuning part 17a cooperates with the first sliding part, and the second lateral fine-tuning part 17b cooperates with the second sliding part to realize the movement of the Y-shaped frame 13 in the direction close to the first support part 41 or in the direction close to the second support part 42. The clamping assembly 20 is fixedly connected to the base 43. One end of the clamping assembly 20 away from the target booster positioning surface 200 also abuts against the third shaft 11c. The clamping assembly 20 is used to prevent the tail support assembly 10 from tipping over and to provide a set clamping force to the target booster 100. One end of the anti-rebound assembly 30 is fixedly connected to the first shaft 11a, and the other end is selectively connected to the base 43.Before the target drone is launched, the tail support ring 12, longitudinal fine-tuning part 14, first lateral fine-tuning part 17a, and second lateral fine-tuning part 17b are controlled to adjust the target drone booster 100 to meet the launch attitude requirements. After the target drone booster 100 is in the launch attitude position, the clamping assembly 20 clamps the third shaft 11c, and both the first torsion spring 15a and the second torsion spring 15b are in a stretched state. After the target drone is launched, the cross frame 11 rotates and falls down around the first sliding part and the second sliding part under the action of the first torsion spring 15a and the second torsion spring 15b. After the cross frame 11 falls down, the anti-rebound mechanism connects with the base 43 to prevent the cross frame 11 from rebounding.

[0039] That is, in the cross-shaped rotating frame 11, the first axis 11a and the third axis 11c are arranged opposite to each other, and the second axis 11b and the fourth axis 11d are arranged opposite to each other.

[0040] In this embodiment of the invention, the shape of the arc-shaped tail support ring 12 should follow the shape of the tail of the booster 100 to ensure better support of the booster 100, wherein the tail support ring 12 can swing freely while supporting the tail of the booster 100.

[0041] Applying the above configuration, a target drone booster fixing device is proposed. This device includes a tailstock assembly, a clamping assembly, an anti-rebound assembly, and a launch mount assembly. The tailstock assembly and launch mount assembly work together to support and fix the booster. The booster's attitude is adjusted using the tailstock ring, longitudinal fine-tuning part, first lateral fine-tuning part, and second lateral fine-tuning part in the tailstock assembly. After the booster's attitude adjustment is complete, the clamping assembly clamps the tailstock assembly, keeping the booster's attitude unchanged until the launch mission is completed. After the launch mission, the tailstock assembly and launch mount assembly work together to secure the tailstock... The component rotates and falls to avoid interfering with the booster. At the same time, the anti-rebound component prevents the tailstock component from rebounding after the target drone is launched. It can be seen that by fixing the target drone booster and adjusting its attitude through this fixing device, the booster can be fixed in all directions and the relative attitude between the booster and the target drone can be adjusted without connection limit. Moreover, the fixing device can ensure the stable fixation of the booster's attitude before launch and will not interfere with the booster during and after launch. It has the advantages of reliable performance and convenient operation. Using this fixing device can significantly shorten the launch preparation time.

One end of the first rotating pin and the second rotating pin are fixedly connected to the two ends of the tail support ring 12, and the other end of the first rotating pin and the second rotating pin are rotatably connected to the two sides of the bifurcation 13a of the Y-shaped frame 13.

[0043] In embodiments of the present invention, such as Figure 3 As shown, the first rotating pin has a thread at the root and a smooth cylindrical surface at the head. There is a light hole on each side of the tail support ring 12. The two rotating pins screw the tail support ring 12 to the upper end of the Y-shaped frame 13. The smooth cylindrical surface of the first rotating pin is rotatably connected to the forked part 13a. Similarly, the second rotating pin is also connected in the same way.

When the longitudinal fine-tuning part 14 is rotated, the Y-shaped frame 13 can be controlled to reciprocate along the axial direction of the first axis 11a within the range of -15mm to 15mm.

[0045] In the above embodiment, in order to limit the rotation between the Y-shaped frame and the first shaft, the Y-shaped frame 13 is provided with an anti-rotation groove, and the first shaft 11a is provided with an anti-rotation part. The anti-rotation groove and the anti-rotation part cooperate to prevent the Y-shaped frame 13 from rotating around the first shaft 11a.

The shoulder of the stepped shaft abuts against the end face of the other end of the second rectangular slider 16b.

[0047] In embodiments of the present invention, such as Figure 3 and 6As shown, the outer contour of the first rectangular slider 16a is rectangular, and one end face of it is provided with a round hole. After it is inserted into the first rectangular through hole 41a, it can only slide left and right and cannot rotate. The second shaft 11b has a small stepped shaft that is inserted into the round hole on the end face of the first rectangular slider 16a, and the shoulder of the shaft abuts against the side end face of the first rectangular slider 16a. Similarly, the second rectangular slider 16b is also designed in this way, so that the cross rotating frame 111 can rotate around the first rectangular slider 16a and the second rectangular slider 16b to ensure that it does not interfere with the booster 100.

[0048] In the above embodiments, to better ensure that the cross-shaped rotating frame rotates and falls down after the booster is launched, such as...

The other end of the second torsion spring 15b is also fixed in the rectangular groove. In the non-docked state, the tail support assembly 10 falls onto the launcher assembly 40 under the action of the torsion spring.

[0049] In the above embodiments, in order to better achieve the adjustment of the lateral displacement of the booster and save costs, the tail support assembly 10 further includes a first end cap 18a and a second end cap 18b.

The pin 34 is used to connect the locking hook 35 to the end of the retaining ring shaft 33 near the second retaining ring 32. The locking hook 35 can rotate around the pin 34. The limiting shaft 37 is connected to the end of the retaining ring shaft 33 away from the second retaining ring 32 and is used to limit the locking hook 35. The retaining ring shaft 33 has a mounting hole 33a, and the V-shaped spring 36 is engaged between the retaining ring shaft 33 and the locking hook 35 through the mounting hole 33a.

[0056] To gain a further understanding of the target launch fixing device provided in the embodiments of the present invention, the assembly process and usage flow of the fixing device are described in detail below:

[0057] like Figure 6 As shown, in the first step, the Y-shaped frame 13, the first rotating pin, the second rotating pin, the tail support ring 12, the longitudinal fine-tuning part 14, and the cross rotating frame 11 are assembled according to the above connection relationship.

[0058] The second step is to insert the second rectangular slider 16b into the first rectangular through hole 41a, with the end containing the cylindrical hole facing inward; the second rectangular slider 16b is installed in the same way.

[0059] The third step is to assemble the first patterned plate 16c, the first torsion spring 15a, the second patterned plate 16d, the second torsion spring 15b, and the cross rotating frame 11 according to the above structural relationship. The first torsion spring 15a and the second torsion spring 15b are only placed in place and are not connected to the corresponding patterned plate or the cross rotating frame 11.

[0060] Fourth step, install and fix the first end cap 18a, the second end cap 18b, the first lateral fine-tuning part 17a, and the second lateral fine-tuning part 17b onto the launcher body assembly 40 according to the above structural relationship.

[0061] Fifth step, connect one end of the torsion spring to the flower-shaped card plate and the other end to the lower end of the cross-shaped rotating frame 1117 for fixation;

[0062] Step 6: Install the fire shield onto the patterned cardboard.

[0063] The seventh step is to screw the anti-rebound mechanism onto the first shaft 11a of the cross-shaped rotating frame 11 via the first retaining ring 31 and the second retaining ring 32.

[0064] Step 8: Install the clamping assembly 20 onto the base 43 via the threaded tube 23;

[0065] In the docking state, rotating the force adjustment rod 25 can cause the top head 21 to press against the third shaft 11c of the cross frame 11 and retract inward by 1mm to 1.5mm, preventing the tail support assembly 10 from tipping over backward and providing a clamping force of 350N to 450N to the booster 100 to fix the booster 100.

[0066] When the launch is complete, the tail support assembly 10 falls down under the action of two torsion springs, and the locking hook 35 of the anti-rebound assembly 30 hooks the base 43 to prevent the tail support assembly 10 from rebounding.

[0067] The usage process is as follows:

[0068] like Figure 1As shown, the first step is to manually press down the locking hook 35 in the anti-rebound component 30 to unlock it and then flip the tail support component 10 to an upright position; the second step is to lock the tail of the booster 100 onto the tail support ring 12, with the head abutting against the positioning surface 200 of a certain type of target drone booster; the third step is to adjust the attitude of the booster 100 through the tail support mechanism so that the booster 1001 meets the launch attitude requirements; the fourth step is to rotate the force adjustment rod 25 of the clamping component 20 so that the top head 21 presses against the third shaft 11c part of the cross frame 11 and retracts inward by 1mm to 1.5mm.

[0069] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0070] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0071] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
