Description

Technical Field

[0001] This invention belongs to the field of remote-controlled and autonomous platform intelligent weapon equipment design, and in particular, an unmanned weapon platform with an adjustable damping buffer device. Background Technology

[0002] Since the introduction of drone swarm technology, its use on the battlefield has received increasing attention from various countries. In modern warfare, the use of various unmanned equipment has revolutionized traditional combat methods. A large number of drones are used to track enemy forces, guide artillery fire, and bomb targets. Due to their high mobility, drones have put ground troops in a very passive position and pose a huge threat to firepower deployment points and combat personnel.

[0003] To counter the threat posed by "low, slow, and small" drones, the conventional hard-kill method is kinetic energy destruction, which involves launching munitions from a launcher to strike the drone. However, considering the small size and agility of these drones, and the recoil inherent in conventional launchers, it is difficult for personnel to accurately track and fire at them in real-time. Therefore, it is necessary to utilize weapon platforms to mount the launchers to achieve precision firing.

[0004] While unmanned weapon platforms have achieved extremely high levels of firepower, protection, and intelligence, the following problems still exist: First, they mostly adopt an integral structure with low modularity. Once a part is damaged, the entire structure needs to be disassembled and reassembled, which greatly affects maintenance efficiency. Second, they mostly use stepper or servo motors with gearboxes, resulting in excessively large weapon platforms and potential transmission backlash. Third, most lack buffers or use a single buffer, making it difficult for the launcher to recover stability quickly, affecting firing accuracy. Fourth, they are mostly designed for ground targets, with a maximum elevation angle of around 40°, making them unable to fire at high elevation angles and resulting in weak anti-drone capabilities. Summary of the Invention

[0005] The purpose of this invention is to provide an unmanned weapon platform mechanism with an adjustable damping buffer device. By clamping the weapon unit and using the buffer device, the pitch and azimuth angles can be adjusted by a torque motor, enabling high-angle firing and precise strikes against unmanned aerial vehicles (UAVs). This enhances the ability of individual soldiers to deal with UAVs, extends the combat range, improves combat effectiveness, and reduces friendly losses.

[0006] The technical solution for achieving the objective of this invention is: an unmanned weapon platform with an adjustable damping buffer device, comprising:

[0007] The cradle mechanism is rotatably mounted on the gimbal mechanism and is used to fix and clamp the launcher barrel and receiver.

[0008] A sight mounting mechanism, mounted on the cradle mechanism, is used to mount a sight;

[0009] The buffer mechanism is installed between the clamp base and the support arm connector of the cradle mechanism to buffer the launcher and thus restore stability under the action of recoil.

[0010] The electronically controlled firing mechanism, mounted on the cradle mechanism and located below the weapon's firing tube, is used to control the firing selector and trigger on the launcher.

[0011] The gimbal mechanism, rotatably mounted on the base mechanism, is used to achieve pitch adjustment of the weapon launcher;

[0012] The base mechanism can be mounted on a fixed platform or a mobile vehicle via a chassis, enabling the weapon platform to be fixed or moved.

[0013] The significant advantages of this invention compared to existing technologies are:

[0014] (1) The unmanned weapon platform mechanism designed in this invention, by clamping the weapon unit and using a buffer device, utilizes a torque motor to drive and adjust the pitch and azimuth angles, enabling high-angle firing and achieving precise strikes against unmanned aerial vehicles (UAVs). This enhances the ability of individual soldier squads to deal with UAVs, extends the combat range, improves combat effectiveness, and reduces friendly losses. Furthermore, it adopts a modular design method, with different mechanisms working together to achieve the overall structure of the unmanned weapon platform, facilitating replacement, maintenance, and upgrades. By changing different clamps, different types of launchers can be clamped.

[0015] (2) The pitch and azimuth angles of the weapon platform are adjusted by using a torque motor, which avoids transmission gaps. At the same time, the weapon platform can be driven to have a pitch angle adjustment range of ±60° and an azimuth angle adjustment range of ±180°, which makes the platform have higher shooting accuracy and a larger shooting range. Meanwhile, the size and weight of the weapon platform are greatly reduced, which meets the needs of high dynamic scenarios such as anti-UAV.

[0016] (3) The present invention innovatively adopts a composite buffer structure that combines a rectangular spring buffer and a friction plate damping structure. After the launcher fires, the buffer not only uses a high-stiffness rectangular spring to absorb huge recoil energy, but also uses friction plates to dissipate mechanical energy, effectively eliminating the reciprocating oscillation of the spring, enabling the launcher to recover stability in a shorter time and greatly improving the accuracy of continuous firing.

[0017] (4) A structure with connecting flanges and crossed roller bearings is introduced on the pitch axis and azimuth axis. The crossed roller bearings are used to bear the overturning moment of the platform when the launcher fires, which reduces the impact of the overturning moment on the motor.

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] Combination Figure 1 The unmanned weapon platform mechanism with adjustable damping buffer device in this embodiment adopts a modular design method and includes a cradle mechanism I, a sight mounting mechanism II, a buffer mechanism III, an electronically controlled firing mechanism IV, a base mechanism V, and a gimbal mechanism VI.

[0028] Combination Figure 1 The cradle mechanism I includes a first cradle support arm 1, a rear clamp end cover 2, a rear clamp base 3, a support arm connector 4, a second cradle support arm 5, a set nut 6, a set stud 7, a set handle 8, a sliding guide rod 9, a front clamp base 10, a front clamp end cover 11, and a flange-type linear bearing 12.

[0029] The first cradle support arm 1, the second cradle support arm 5, the two support arm connectors 4, and the two sliding guide rods 9 constitute the main frame of the cradle; the first cradle support arm 1 and the second cradle support arm 5 are arranged opposite to each other and the two ends of the two support arms are fixedly connected by the two support arm connectors 4; the two sliding guide rods 9 pass through the front clamp base 10, the rear clamp base 3, and the buffer mechanism III and are fixed at both ends to the support arm connectors 4 by screws;

[0030] The front clamp base 10 and the front clamp end cap 11 are U-shaped clips that together form the front clamp, which is used to support the launcher barrel. The front clamp base 10 and the front clamp end cap 11 are connected by bolts and thus fix the launcher barrel. The front clamp base 10 has two holes symmetrically opened at both ends, and two sliding guide rods 9 pass through the two ends of the front clamp base 10 respectively.

[0031] The rear clamp consists of a rear clamp end cap 2, a rear clamp base 3, a set nut 6, a set stud 7, and a set handle 8. One end of the rear clamp end cap 2 is hinged to one end of the rear clamp base 3. The other end of the rear clamp base 3 has a hole in which the set stud 7 is fixedly installed. The other end of the rear clamp end cap 2 has an opening slot. In use, the set stud 7 passes through the opening slot, and the set nut 6 engages with the set stud 7 to lock the rear clamp end cap 2. The set handle 8 is fixedly connected to the set nut 6 and is used to facilitate tightening and loosening of the set nut 6. The rear clamp is a clamp type; adjusting the tightening and loosening of the set nut 6 via the set handle 8 controls the clamping and loosening of the rear clamp on the transmitter receiver.

[0032] Four flange-type linear bearings 12 are respectively installed in conjunction with the through holes at both ends of the rear clamp base 3 and the front clamp base 10, and are fixed to the rear clamp base 3 and the front clamp base 10 with screws; the sliding guide rod 9 passes through the flange-type linear bearings 12; the flange-type linear bearings 12 can reduce the friction force when the front clamp and the rear clamp hold the launcher and slide along the sliding guide rod 9, so that the clamp movement is more stable.

[0033] Combination Figure 2 The sight mounting mechanism II includes a sight mounting base 13. The lower part of the sight mounting base 13 mates with the groove at the top of the first cradle support arm 1 and is fixed by the pin hole at the tail of the sight mounting base 13. The top of the sight mounting base 13 is provided with a Picatinny rail for mounting a smart sight. When the cradle mechanism I moves, the sight mounting base 13 can hold the sight and follow its movement.

[0034] Combination Figure 3 The buffer mechanism III includes a spring guide inner cylinder 14, a buffer spring 15, an adjusting bolt 16, a buffer outer cylinder 17, a friction plate 18, and an adjusting spring 19; the buffer mechanism III is provided with four sets, which are respectively located at both ends of the two sliding guide rods 9 in the cradle mechanism I.

[0035] The inner cylinder 14 of the spring guide tube and the outer cylinder 17 of the buffer are coaxially fitted and can slide relative to each other. The buffer spring 15 is coaxially placed in the inner cylinder 14 of the spring guide tube. The friction plate 18 is coaxially fitted with the inner cylinder 14 of the spring guide tube and is disposed between the outer cylinder wall of the inner cylinder 14 of the spring guide tube and the inner cylinder wall of the outer cylinder 17 of the buffer. Preferably, the friction plate 18 is placed in the groove of the inner wall of the outer cylinder 17 of the buffer, one at the top and one at the bottom. The adjusting spring 19 is placed in the cylindrical hole provided on the side wall of the outer cylinder 17 of the buffer. The adjusting bolt 16 is threadedly connected to the cylindrical hole on the outer cylinder 17 of the buffer. The end of the adjusting bolt 16 contacts one end of the adjusting spring 19, and the other end of the adjusting spring 19 contacts the friction plate 18. By controlling the adjusting bolt 16, the adjusting spring 19 is squeezed, thereby increasing the friction force of the friction plate 18 on the inner cylinder 14 of the spring guide tube, thereby achieving the function of adjusting the damping.

[0036] The sliding guide rod 9 in the cradle mechanism I passes through the inner ring of the buffer spring 15 in the buffer mechanism III, and the outer cylinder 17 of the buffer is fixedly connected to the support arm connectors 4 at both ends.

[0037] Preferably, the buffer spring 15 is a rectangular spring, which has the characteristics of high stiffness, long service life and high energy storage. Compared with a round cross-section spring, it has a shorter length while meeting the requirements of buffering force, which is conducive to meeting the design requirements of small size of weapon platform.

[0038] Two sets of buffer mechanisms III are located at the two ends of the sliding guide rod 9, and the end of the buffer outer cylinder 17 is fixed to the support arm connector 4. When the launcher fires, due to the recoil, the launcher, the front clamp, and the rear clamp reciprocate along the sliding guide rod 9. At this time, when the rear clamp slides into contact with the inner cylinder 14 of the spring guide tube, it causes the inner cylinder 14 of the spring guide tube to compress the buffer spring 15, and the inner cylinder 14 of the spring guide tube and the friction plate 18 undergo relative displacement. The buffer mechanism III uses the deformation of the buffer spring 15 to absorb the recoil energy when the launcher fires, and at the same time uses the friction plate 18 to dissipate mechanical energy, thereby suppressing the impact of recoil on the weapon platform and improving firing accuracy.

[0039] Combination Figure 4The electronically controlled firing mechanism IV includes a trigger lever 20, a selector servo disc 21, a selector servo 22, a servo connecting frame 23, a trigger servo 24, and a trigger servo disc 25. The selector servo 22 and the trigger servo 24 are fixedly installed in two mounting slots at the lower part of the servo connecting frame 23. The selector servo disc 21 is connected to the upper shaft of the selector servo 22 and fixed with screws, and is used to adjust the firing mode by turning the selector on the launcher. The trigger servo disc 25 is installed on the shaft of the trigger servo 24 and fixed with screws. The trigger lever 20 is fixed to the trigger servo disc 25 and is used to turn the trigger to control the launcher to fire. The tail of the servo connecting frame 23 of the electronically controlled firing mechanism IV is installed on the surface of the rear clamp base 3.

[0040] In this embodiment, the fire selector servo disc 22 in the electronically controlled firing mechanism IV is designed as a slot, ensuring that the end of the fire selector lever is located in the slot during installation; the trigger servo disc 25 is a swing arm type with two mounting holes at the end for mounting the trigger lever 20, which is aligned with the end of the trigger; when the fire selector servo 22 and the trigger servo 24 control the rotation of the fire selector servo disc 22 and the trigger servo disc 25, the fire selector and trigger can be pulled, realizing the switching of firing modes and firing.

[0041] Combination Figure 5 The base mechanism V includes a connecting flange 26, a first crossed roller bearing 27, a bearing gasket 28, a directional motor 29, a motor mounting base 30, and a chassis 31. The connecting flange 26 is interference-fitted with the inner ring of the first crossed roller bearing 27, and the outer ring of the first crossed roller bearing 27 is interference-fitted with the motor mounting base 30, thereby rotatably connecting the connecting flange 26 and the motor mounting base 30. The bearing gasket 28 is placed between the crossed roller bearing 27 and the motor mounting base 30. The bottom groove of the connecting flange 26 contacts and is fixed to the output shaft of the directional motor 29. The housing of the directional motor 29 is fixedly installed in the motor mounting base 30, and the motor mounting base 30 is fixed on the chassis 31.

[0042] In this embodiment, the connecting flange 26 is used in conjunction with the first crossed roller 27 for transitional connection instead of directly connecting the output shaft of the azimuth motor 29 to the gimbal structure VI. The first crossed roller 27 is used to bear the overturning moment brought about by the launcher firing, preventing the overturning moment from acting directly on the azimuth motor 29 and causing fatigue damage to the azimuth motor 29.

[0043] Combination Figure 6The gimbal mechanism VI includes a second crossed roller bearing 32, a U-shaped support arm 33, a bearing end cap 34, a motor end cap 35, and a pitch motor 36. The outer ring of the second crossed roller bearing 32 is interference-fitted with the right trunnion hole of the U-shaped support arm 33, and the inner ring of the second crossed roller bearing 32 is interference-fitted with the side boss of the first cradle support arm 1 in the cradle mechanism I. The second crossed roller bearing 32 is used to bear the overturning moment brought to the platform when the launcher fires. The pitch motor 36 is fixed in the left trunnion hole of the U-shaped support arm 33, and its output shaft is installed in the side mounting groove of the second cradle support arm 5 in the cradle mechanism I and fixedly connected. The bearing end cap 34 and the motor end cap 35 are respectively installed in the two trunnion hole ports of the U-shaped support arm 33 for dust prevention. The bottom of the U-shaped support arm 33 is fixedly connected to the connecting flange 26 in the base mechanism V.

[0044] In this embodiment, the gimbal mechanism VI adopts a two-axis structure design, which has the advantages of simpler structure, faster response, and lower cost. The gimbal mechanism VI is mainly used to connect the cradle mechanism I and the base mechanism V, and to realize the pitch and azimuth adjustment functions of the unmanned weapon platform.

[0045] In this embodiment, the pitch angle adjustment of the weapon platform is achieved by rotating the output shaft of the pitch motor 36 in the gimbal mechanism VI, which drives the second cradle support arm 5 in the cradle mechanism I to rotate; the azimuth angle adjustment is achieved by rotating the output shaft of the azimuth motor 29 in the base mechanism V, which drives the connecting flange 26 to rotate relative to the motor mounting base 30, and drives the U-shaped support arm 33 to rotate, thereby driving the gimbal mechanism VI to rotate.

[0046] In this embodiment, the pitch motor 36 drives the weapon platform to achieve a pitch angle adjustment range of ±60°, and the azimuth motor 29 drives the weapon platform to achieve an azimuth angle adjustment range of ±180°.

[0047] In this embodiment, the buffer mechanism III is designed with an adjustable damping structure. By setting a friction plate 18 between the inner cylinder 14 of the spring guide tube and the outer cylinder 17 of the buffer, the friction between the friction plate 18 and the outer wall of the inner cylinder 14 of the spring guide tube is used to accelerate the conversion of recoil energy, so that the launcher can stop more quickly on the sliding guide rod 9. By screwing in and out the adjusting bolt 16, the pressure applied by the adjusting spring 19 to the friction plate 18 can be controlled, thereby controlling the magnitude of the friction force between the friction plate and the outer wall of the inner cylinder, and achieving the purpose of adjusting the damping magnitude.

[0048] In this embodiment, the working principle of the unmanned weapon platform mechanism with adjustable damping buffer device of the present invention is as follows: After receiving angular displacement commands, the azimuth motor 29 and pitch motor 36 inside the platform, supported by the first crossed roller bearing 27 and the second crossed roller bearing 32, quickly drive the cradle mechanism I and the gimbal mechanism VI to rotate and aim at the target. When the firing condition is met, the trigger servo motor 24 in the remote cloud platform controls the rotation of the shaft, driving the trigger lever 20 to pull the launcher trigger. At the moment of firing, the launcher and the clamp reciprocate on the sliding guide rod 9 in the cradle mechanism I, compressing the buffer mechanism III. Under the dual action of spring energy storage and internal friction energy dissipation, the recoil energy is quickly absorbed and attenuated, allowing the launcher to quickly return to a stable position and prepare for the next shot, achieving accurate firing.
