Description

Technical Field

[0001] The present invention belongs to the technical field of unmanned combat platforms, and particularly relates to a liftable pan-tilt for an unmanned combat platform. Background Art

[0002] In the modern field of unmanned combat, unmanned combat platforms have been increasingly widely used due to their unique advantages. As a core component of an unmanned combat platform, the pan-tilt plays a crucial role in tasks such as reconnaissance, surveillance, and strike. However, there are some problems to be solved in the design of the pan-tilt and related structures of current existing unmanned combat platforms.

[0003] First of all, many existing pan-tilts of unmanned combat platforms lack effective angle limit and stabilization structures. In a complex and changeable combat environment, whether facing intense firepower confrontation, harsh weather conditions, or rough and bumpy terrain, the pan-tilt is difficult to maintain a stable state, which in turn makes it difficult to accurately locate the target. This undoubtedly greatly affects the execution effect of combat tasks and reduces the accuracy and efficiency of strikes.

[0004] Secondly, most platforms do not have a liftable function. The pan-tilt without a liftable function makes the platform less adaptable to different terrains and combat scenarios, unable to fully meet diverse combat requirements, and severely restricts the combat effectiveness of the unmanned combat platform. Moreover, when not in combat or facing potential threats, the pan-tilt cannot be housed in an explosion-proof shell. This directly exposes the pan-tilt and key equipment it carries, such as reconnaissance equipment and weapon systems, to damage from factors such as collisions, explosion shocks, and harsh environmental erosion, seriously affecting the continuous combat ability of the combat platform.

[0005] In addition, attention also needs to be paid to aspects such as the stability, light weight, miniaturization, and modularization of the pan-tilt. Insufficient stability makes the pan-tilt prone to shaking during task execution, affecting the accuracy of data collection and weapon aiming; an overweight pan-tilt increases the overall weight of the platform, reduces energy utilization efficiency, and shortens the platform's endurance time; a large volume limits its mobility in narrow spaces and is not conducive to the flexible deployment of the platform in complex environments; the imperfect modular design results in poor flexibility of the pan-tilt in meeting different combat task requirements. When it is necessary to replace or upgrade functional modules, the maintenance and replacement of modules are not convenient enough, which not only increases the maintenance cost but also reduces the platform's usability and battlefield response speed. Summary of the Invention

[0006] The object of the present invention is to provide a liftable pan-tilt for an unmanned combat platform. This pan-tilt can not only be smoothly lifted from the explosion-proof housing when necessary and accurately adjust its height according to combat missions, but also has the characteristics of good stability, light weight, miniaturization and modularization. It can effectively protect the weapon module and improve the combat effectiveness and survivability of the unmanned combat platform in various complex combat environments.

[0007] The technical solution for achieving the object of the present invention is as follows:

[0008] A liftable pan-tilt for an unmanned combat platform, comprising a pan-tilt and a lifting mechanism;

[0009] The pan-tilt includes a base, an azimuth axis system, a pitching mechanism, a control box and a control line pipe;

[0010] The base is fixed on the lifting mechanism; the azimuth axis system connects the pitching mechanism and the base, and is used to drive the entire pitching mechanism and the weapon system to adjust the azimuth in the horizontal direction; the pitching mechanism is used to drive the pitching movement of the weapon system; the control box is used to receive control instructions and, through the control line pipe as a signal transmission link, send control instructions to the azimuth axis system and the pitching mechanism, so that the weapon system always aims at the target;

[0011] The lifting mechanism is used to adjust the height of the pan-tilt through lifting movement.

[0012] Compared with the prior art, the present invention has the following remarkable advantages:

[0013] (1) The liftable design enables the pan-tilt carrying the rocket launcher to flexibly adjust its height according to actual combat needs. When conducting reconnaissance and strikes on targets at different heights, it can quickly adjust the rocket launcher to the optimal combat height range, effectively improving combat effectiveness and the accuracy of data acquisition. At the same time, it can be stored in the explosion-proof housing during non-combat or in the face of potential threats, providing reliable protection for key equipment such as rocket launchers; (2) The two-degree-of-freedom design greatly simplifies the structure of the pan-tilt on the basis of meeting the effectiveness requirements for carrying out combat missions with the rocket launcher, shortens the production cycle and reduces the manufacturing cost; the reduction in the number of components reduces the probability of mechanical failures in complex combat environments, which is conducive to the execution of long-term combat missions; (3) The light-weight and miniaturized design improves the energy utilization efficiency and mobility of the platform, making the unmanned combat platform carrying the rocket launcher more flexible; the modular design enables the pan-tilt to quickly adapt to different combat mission requirements, facilitating the replacement and upgrade of weapon modules, etc. Description of the Drawings

[0015] Figure 2 is the main structural schematic diagram of the pan-tilt.

[0017] The present invention will be further introduced below in conjunction with the accompanying drawings and specific embodiments.

[0018] Combined with Figures 1-3 , a liftable pan-tilt for an unmanned combat platform of the present invention includes a pan-tilt and a lifting mechanism.

[0019] The pan-tilt includes a base 9, an azimuth axis system, a pitching mechanism, a control box, and a control line pipe; the lifting mechanism includes a fixing plate 17, a guide rail 18, an upper scissors arm 19, an arm support pin joint 20, a hydraulic cylinder 21, a lower scissors arm 22, and a bracket 23.

[0020] Furthermore, the base 9 has high strength, high rigidity, and good anti-impact and anti-vibration characteristics. In actual combat scenarios, when the weapon carried, such as a rocket launcher, generates a strong recoil impact during launch, according to the principle of structural mechanics, the recoil force is conducted to the main structure of the unmanned combat platform in a reasonable stress distribution form, thereby ensuring that the overall structure of the pan-tilt is not damaged; during the dynamic operations of the pan-tilt, such as rapid turning and pitching, the base 9, relying on its inertial stability characteristics, effectively resists the inertial force interference caused by the moving components, and guarantees the relative position accuracy and motion coordination among the various moving components.

[0021] Furthermore, the azimuth axis system includes an azimuth axis motor 11, an azimuth axis bracket 7, a small gear 10, and a large gear 16. The azimuth axis motor 11 is fixed in the base 9 as a power generating unit. The output shaft of the azimuth axis motor 11 is connected to the small gear 10. The small gear 10 meshes with the large gear 16. The large gear 16 is connected to the azimuth axis bracket 7 and is supported on the base 9 by bearings; when the control box 3 issues a control command, the output shaft of the azimuth axis motor 11 starts to rotate, driving the small gear 10 to rotate. The meshing transmission between the small gear 10 and the large gear 16 follows the kinematics and dynamics principles of gear transmission. Through pre-designed parameters such as the gear module and the tooth number ratio, the high-speed and low-torque rotational motion of the motor is converted into the low-speed and high-torque precise rotation of the azimuth axis bracket 7 on the azimuth axis. This rotation drives the entire pitching mechanism and the weapon system to achieve high-precision azimuth adjustment in the horizontal direction, and can meet the requirements of quickly and accurately aiming at targets at different horizontal angles.

[0022] Furthermore, the pitching mechanism takes the pitching axis bracket 8 as the core load-bearing structure, and includes a pitching axis motor 14, a gun barrel fixing box 13, a gun barrel 15, a pitching bearing 5, a limit plate 4, and a limit slider 6. Multiple gun barrels 15 are tightly installed in the gun barrel fixing box 13 in a 2×2 arrangement, and are fastened by bolts through upper and lower clamps to ensure that the gun barrel 15 can withstand the impact during firing and the vibration generated by platform maneuvering in the gun barrel fixing box 13, and maintain a stable firing posture. There are 6 groups of M10 threaded holes on the pitching axis bracket 8, and the gun barrel fixing box 13 is connected to the pitching axis bracket 8 through threaded connection, so as to ensure the stable installation of the gun barrel fixing box 13, and also facilitate the flexible loading and unloading of the gun barrel fixing box 13 and other weapon modules, enabling the pan-tilt to quickly adapt to the requirements of different combat missions. Both ends of the pitching axis bracket 8 are supported on the azimuth axis bracket 7 through the pitching bearing 5. The pitching axis motor 14 is fixed to the side end of the gun barrel fixing box 13, and the output shaft of the pitching axis motor is connected to the pitching axis bracket 8. The torque of the pitching axis motor 14 is transmitted to the pitching axis bracket 8 through the close fit of the pitching bearing 5. The connection and cooperation of the pitching bearing 5 and the pitching axis bracket 8 provide stable support and drive the gun barrel fixing box 13 to perform pitching motion on the azimuth axis bracket 7 to achieve aiming at targets at different heights. The limit slider 6 is fixed to the pitching axis bracket 8, and the limit plate 4 is installed on the azimuth axis bracket 7 to provide a limit boundary for the movement of the limit slider 6, so that it can rotate within the range defined by the pitching axis bracket 8. Although the limit plate 4 and the limit slider 6 are not directly connected to the gun barrel fixing box 13 and the gun barrel 15, they indirectly affect the movement of the gun barrel 15 by acting on the pitching axis bracket 8. This connection and cooperation method ensures that the safety range will not be exceeded during the pitching motion, effectively preventing mechanical component damage and weapon system failures caused by excessive pitching.

[0023] When the control box 3 issues a pitching motion command, the pitching axis motor 14 starts to operate as a power source, driving the gun barrel fixing box 13 and the gun barrel 15 to achieve pitching motion. During this process, the pitching axis motor 14 and the pitching bearing 5 work together to convert the rotational motion of the motor into the pitching angle change of the gun barrel in the vertical plane. The limit plate 4 and the limit slider 6 accurately define the movement range of the gun barrel in the pitching direction through a mechanical contact type limit mechanism. They limit the maximum and minimum allowable pitching angles of the gun barrel, preventing mechanical component overload, fatigue damage, or weapon system functional failures caused by excessive pitching from the mechanical structure level, and ensuring the stable and reliable operation of the pan-tilt within the preset safe working range.

[0024] Further, the control box 3 is fixed on the gun barrel fixing box 13 as the control core hub of the pan-tilt, receives control instructions from the main control system of the unmanned combat platform or the remote operation terminal, and combines the pan-tilt position, attitude, and target information real-time feedback by the detector 12 set on the gun barrel fixing box 13, and uses control theory and algorithms for data processing and decision analysis. The control line tube 2 is the key physical link for signal transmission, and constructs an information interaction channel between the control box 3 and each executing component inside the pan-tilt, such as the azimuth axis motor 11, the elevation axis motor 14, the detector 12, etc. According to the results of processing and analysis, the control box 3 sends precise control instructions to the corresponding motors through the control line tube 2 to achieve precise pointing and dynamic tracking of the gun barrel 15. For example, during the target tracking process, the control box 3 calculates the required elevation angle and azimuth angle for the pan-tilt to adjust in real time based on the target tracking algorithm according to the target position change information provided by the detector 12, and then sends instructions to the corresponding motors through the control line tube 2. The motors drive each component of the pan-tilt to move quickly and precisely according to the instructions along the preset motion trajectory, so that the gun barrel 15 always aims at the target. Even when the target shows high-speed maneuverability or the battlefield environment is in a complex and changeable situation, it can still ensure that the weapon system has a high hit rate and combat effectiveness.

[0025] Further, the fixing plate 17 in the lifting mechanism is used as the basic support component to fix the base 9 and stably install it on the unmanned combat platform. The guide rail 18 is installed on the fixing plate 17 to provide guidance for the movement of the upper scissor arm 19. The upper scissor arm 19 and the lower scissor arm 22 are connected to each other through the arm support pin hinge point 20 to form a telescopic structure. One end of the hydraulic cylinder is connected to the upper scissor arm 19, and the other end is connected to the lower scissor arm 22, so as to realize the expansion or folding of the scissor unit to achieve the lifting function of the pan-tilt. When the control box 3 receives the lifting instruction from the main control system of the unmanned combat platform or the remote operation terminal, the control box 3 sends a corresponding signal to the hydraulic cylinder 21. If it is necessary to raise the pan-tilt, the hydraulic cylinder 21 extends, pushing the upper scissor arm 19 to slide along the guide rail 18 and move upward, and then driving the connected pan-tilt to rise smoothly; if it is necessary to lower the pan-tilt, the hydraulic cylinder 21 contracts, and the upper scissor arm 19 moves downward along the guide rail 18, and the pan-tilt also descends smoothly.

[0026] Further, the bracket 23 is fixed to the lower end of the upper scissor arm 19 to provide additional support and stability for the lifting mechanism. During the lifting and lowering process of the pan-tilt, the bracket 23 can effectively share the weight, prevent the lifting mechanism from shaking or tilting, and ensure the smoothness and safety of the pan-tilt during the lifting and lowering process.

[0027] The liftable pan-tilt of the unmanned combat platform of the present invention allows the operator to send commands through the main control system of the unmanned combat platform or a remote operation terminal when performing combat missions. When it is necessary to adjust the height of the pan-tilt, the control box 3 controls the lifting mechanism to move to achieve the lifting of the pan-tilt; when conducting reconnaissance and strikes on targets, the control box 3 precisely controls the azimuth axis motor 11 and the pitch axis motor 14 based on the information fed back by the detector 12, enabling the pan-tilt to drive the weapon system such as a rocket launcher to complete the aiming and striking actions on the target.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
