Description

Technical Field

[0001] This invention relates to the technical field of low-altitude defense, specifically to an aerial directional intelligent support suitable for physical anti-device devices. Background Technology

[0002] With the rapid development of drone technology, the application of various civilian and commercial drones is becoming increasingly widespread. However, this has also brought about a series of low-altitude safety hazards, with frequent occurrences of unauthorized and illegal drone flights posing serious threats to public safety, military facilities, and important locations. Against this backdrop, counter-drone technology has developed rapidly. Among these countermeasures, physical strikes using small explosive devices serve as the last line of defense and are currently one of the most effective countermeasures.

[0003] However, using a small drone as a mounting platform allows for the targeted delivery and detonation of internal explosives once within countermeasure range. While the device's lightweight and thin design facilitates the deployment of multiple explosives on a single drone, it also reduces its wind resistance during aerial combat. To minimize collateral damage to the drone platform, the device needs to be detached and allowed to fall a certain distance before being detonated. During this descent, the strength and direction of the airflow severely interfere with the device's directional strike capability. Furthermore, the drone platform, carrying a relatively high and lightweight countermeasure device, cannot stand stably on the ground and take off, significantly limiting the safety and practicality of this type of countermeasure device. Summary of the Invention

[0004] The purpose of this invention is to provide a smart aerial orientation support suitable for physical anti-device devices, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a smart aerial orientation support suitable for physical anti-device devices, comprising an outer frame and an adjustment component two. The outer frame contains a drive component for providing driving force, and the drive component includes a small servo motor, a connecting shaft, and a gear. The output end of the small servo motor is fitted with the connecting shaft, and a gear is mounted outside the connecting shaft. An adjustment component one for assisting position adjustment is mounted outside the gear. The adjustment component one includes a front support rack, a front support guide rod, and a front support. A front support is mounted at one end of the front support rack, and front support guide rods are mounted on both sides of the bottom of the front support. The adjustment component two for synchronous position adjustment is mounted below the adjustment component one, and the adjustment component two includes a rear support rack, a rear support, and a rear support guide rod. A rear support is mounted at the middle of one end of the rear support rack, and rear supports are mounted on both sides of the bottom of the rear support.

[0006] Furthermore, the drive assembly also includes a fixing plate, one end of the connecting shaft is fitted with the fixing plate, and the fixing plate is fixedly disposed inside the outer frame.

[0007] Furthermore, threaded holes are provided at the four corners of the inner frame, and the outer frame is hollow.

[0008] Furthermore, the gear is engaged with the front support rack and the rear support rack.

[0009] Furthermore, the front support rack and the rear support rack are arranged in parallel, and the rear support rack has the same length.

[0010] Furthermore, there are two front support guide rods and two rear support guide rods, and the front support guide rods and the rear support guide rods are of the same length.

[0011] Furthermore, the front support guide rod and the rear support guide rod are symmetrically distributed on both sides of the UAV countermeasure device, and the inner sidewalls of the front support guide rod and the rear support guide rod are in contact with the outer sidewall of the UAV countermeasure device.

[0012] Furthermore, a pressure sensor is provided at the bottom end of the front bracket near the small servo motor, and the front bracket and the rear bracket are slidably disposed inside the outer frame.

[0013] Furthermore, the control method is as follows: Status monitoring and takeoff judgment steps: Real-time monitoring of the pressure signal of the pressure sensor set at the bottom of the front support; When the pressure signal is detected to disappear, it is determined that the UAV carrier has taken off carrying the UAV countermeasure device.

[0014] Clamping guide mode switching steps: After takeoff is determined, a forward rotation command is sent to the small servo motor of the drive component. The small servo motor drives the front bracket rack and the rear bracket rack to move towards each other through the connecting shaft and gear, so that the front bracket and the rear bracket retract inward until the inner sidewalls of the front bracket guide rod and the rear bracket guide rod are attached to both sides of the UAV countermeasure device, forming a limiting guide channel for it.

[0015] Reset Step: After the UAV countermeasure device is launched and a preset delay time has elapsed, a reverse rotation command is sent to the small servo motor, driving it to synchronously drive the front support rack and the rear support rack to move in opposite directions through the connecting shaft and gear, thereby causing the front support and the rear support to unfold outward and return to the initial unfolded support state.

[0016] This invention provides a smart aerial orientation support suitable for physical anti-device devices, which has the following beneficial effects:

[0017] 1. This invention forms a precise limiting and guiding structure through the front support guide rod and the rear support guide rod. Its inner side wall is closely fitted with the outer side wall of the UAV countermeasure device, which can effectively limit the lateral sway of the countermeasure device, avoid airflow interference, ensure that the countermeasure device is smoothly thrown along the preset direction, improve the directional strike hit rate of the UAV countermeasure device against the target, and greatly enhance the strike effectiveness of the small-dose directional countermeasure device.

[0018] 2. This invention integrates the dual functions of take-off and landing support and directional throwing guidance. In the initial state, the front and rear supports unfold to form a stable support platform, which can directly provide a smooth take-off and landing platform for the UAV with load countermeasures device without the need for additional take-off and landing equipment. This simplifies the overall structure of the anti-UAV system and reduces equipment investment and maintenance costs. In addition, the support adopts a structural design in which the outer frame is threadedly connected to the UAV platform and the drive components are firmly fixed by a fixing plate, ensuring the stability of the connection between the support and the UAV platform and avoiding loosening or displacement during operation. At the same time, the front and rear supports can slide and adjust to adapt to different specifications of UAV countermeasures devices, improving the versatility and adaptability of the support and further expanding its application range.

Detailed Implementation

[0025] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0026] like Figures 1-5As shown, a smart aerial directional support suitable for physical anti-drone devices includes an outer frame 1, a drone anti-drone device 2, a threaded hole 3, a drive assembly 4, a small servo motor 401, a connecting shaft 402, a gear 403, a fixing plate 404, an adjustment assembly 5, a front support rack 501, a front support guide rod 502, a front support 503, an adjustment assembly 6, a rear support rack 601, a rear support 602, and a rear support guide rod 603. The drive assembly 4, which provides driving force, is located inside the outer frame 1. The drive assembly 4 includes a small servo motor 401, a connecting shaft 402, and a gear 403. The output end of the small servo motor 401 is mounted with the connecting shaft 402, and the gear 403 is located outside the connecting shaft 402. The gear 403 is connected to the front support rack 501. The rack and pinion 501 are meshed with the gear 403 and the rear rack and pinion 601. The gear 403 has an adjustment component 5 for auxiliary position adjustment on its exterior. The adjustment component 5 includes a front rack and pinion 501, a front guide rod 502, and a front support 503. The front support 503 is mounted on one end of the front rack and pinion 501. Front guide rods 502 are located on both sides of the bottom of the front support 503. There are two front guide rods 502 and two rear guide rods 603, and they are of the same length. The front guide rods 502 and 603 are symmetrically distributed on both sides of the UAV countermeasure device 2, and the inner walls of the front guide rods 502 and 603 are aligned with the UAV countermeasure device. The outer walls of device 2 are fitted together. The front support rack 501 and the rear support rack 601 are parallel and of the same length. The adjustment component 2 6 for position synchronization adjustment is installed below the adjustment component 1 5. The adjustment component 2 6 includes the rear support rack 601, the rear support 602, and the rear support guide rod 603. The rear support 602 is provided at the middle of one end of the rear support rack 601, and the rear support 602 is installed on both sides of the bottom of the rear support rack 602. The drive component 4 also includes a fixing plate 404. The fixing plate 404 is installed at one end of the connecting shaft 402 and is fixedly installed inside the outer frame 1. A pressure sensor is provided at the bottom end of the front support 503 near the small servo motor 401. The front support 501 The front support 503 and rear support 602 are slidably mounted inside the outer frame 1. The fixing plate 404 in the drive assembly 4 fixes the connecting shaft 402 and the small servo motor 401 inside the outer frame 1, ensuring the stability of the drive structure and preventing loosening or displacement during operation. In the initial state, the front support 503 and rear support 602 are at their maximum distance. At this time, the front support guide rod 502 and the rear support guide rod 603 are symmetrically unfolded, forming a stable support platform for the smooth take-off and landing of the drone carrying the drone countermeasure device 2. At this time, the pressure sensor at the bottom of the front support 503 is under pressure, monitoring the load status of the drone carrier and the countermeasure device in real time, and transmitting the pressure signal to the control system. When the drone carrier carrying the drone countermeasure device 2 takes off...When the pressure sensor at the bottom of the front bracket 503 loses its pressure, it immediately sends a signal back to the control system. Upon receiving the signal, the control system sends a forward rotation command to the small servo motor 401. After the small servo motor 401 starts, its output drives the connecting shaft 402 to rotate. The gear 403 outside the connecting shaft 402 rotates synchronously. Since the gear 403 meshes with the front bracket rack 501 and the rear bracket rack 601 respectively, and the front bracket rack 501 and the rear bracket rack 601 are parallel and of the same length, the rotation of the gear 403 synchronously pulls the front bracket rack 501 and the rear bracket rack 601 to move towards each other, thereby causing the front bracket 503 and the rear bracket 602 to retract inwards. After the front bracket 503 and the rear bracket 602 retract to their designated positions, the front bracket guide rod 502 and the rear bracket guide rod 603 synchronously adhere to both sides of the UAV countermeasure device 2. Their inner walls are tightly fitted with the outer walls of the UAV countermeasure device 2, forming a precise limiting and guiding structure that effectively restricts the UAV. The lateral offset of countermeasure device 2 prevents airflow and wind from interfering with its throwing direction. At this time, the UAV countermeasure device 2 is positioned within the guide channel formed by the support frame. When the UAV platform issues a throwing command, the UAV countermeasure device 2 falls smoothly along the guide channel formed by the front support guide rod 502 and the rear support guide rod 603, achieving directional throwing in mid-air and ensuring strike accuracy. After the UAV countermeasure device 2 is thrown, the control system delays for a preset time to match the duration of the countermeasure device's free fall along the guide channel, and sends a reverse rotation command to the small servo motor 401. The small servo motor 401 rotates in reverse, driving the front support rack 501 and the rear support rack 601 to move in opposite directions via the connecting shaft 402 and gear 403. This, in turn, pushes the front support 503 and the rear support 602 outwards, restoring them to their initial maximum spacing. At this time, the pressure sensor at the bottom of the front support 503 is again in a ready-to-bear-pressure state, and the support returns to the take-off and landing support mode, providing a stable platform for the UAV platform's return landing.

[0027] like Figure 1 , Figure 2 and Figure 4 As shown, threaded holes 3 are provided at the four corners inside the outer frame 1, and the outer frame 1 is hollow. The outer frame 1 serves as the load-bearing base of the entire bracket. The threaded holes 3 at the four corners inside the frame are used to achieve a stable connection with the UAV platform. The hollow outer frame 1 structure reduces the overall weight and provides installation space for the internal drive component 4, adjustment component 1 5, and adjustment component 2 6.

[0028] In summary, this aerial directional intelligent support suitable for physical anti-device devices is first based on... Figures 1-5The structure shown in the diagram uses the outer frame 1 as the supporting base for the entire bracket. The threaded holes 3 at its four corners are used for a stable connection with the UAV platform. The hollow outer frame 1 reduces overall weight and provides installation space for the internal drive assembly 4, adjustment assembly 1 5, and adjustment assembly 2 6. The fixing plate 404 in the drive assembly 4 fixes the connecting shaft 402 and the small servo motor 401 inside the outer frame 1, ensuring the stability of the drive structure and preventing loosening or displacement during operation. In the initial state, the front bracket 503 and the rear bracket 602 are at their maximum distance. At this time, the front bracket guide rod 502 and the rear bracket guide rod 603 are symmetrically deployed, forming a stable support platform for the UAV carrying the UAV countermeasure device 2. During stable takeoff and landing, the pressure sensor at the bottom of the front support 503 is under pressure, monitoring the load on the UAV platform and countermeasure device in real time, and transmitting the pressure signal to the control system. When the UAV platform carrying the UAV countermeasure device 2 takes off, the pressure on the pressure sensor at the bottom of the front support 503 disappears, and the sensor immediately sends a signal back to the control system. After receiving the signal, the control system sends a forward rotation command to the small servo motor 401. After the small servo motor 401 starts, its output drives the connecting shaft 402 to rotate. The gear 403 outside the connecting shaft 402 rotates synchronously. Since the gear 403 is meshed with the front support rack 501 and the rear support rack 601 respectively, and the front support rack 501 and the rear support rack 601 are parallel... Distributed and of equal length, the rotation of gear 403 synchronously pulls the front support rack 501 and the rear support rack 601 to move towards each other, thereby causing the front support 503 and the rear support 602 to retract inward. After the front support 503 and the rear support 602 retract to a limited position, the front support guide rod 502 and the rear support guide rod 603 synchronously adhere to both sides of the UAV countermeasure device 2, with their inner sidewalls tightly adhering to the outer sidewalls of the UAV countermeasure device 2, forming a precise limiting and guiding structure. This effectively limits the lateral deviation of the UAV countermeasure device 2 and avoids interference from airflow and wind on its throwing direction. At this time, the UAV countermeasure device 2 is located within the guide channel formed by the support. When the UAV platform issues a throwing command, the UAV countermeasure device 2 moves along the front support guide rod 501... The 02 and the rear support guide rod 603 form a guide channel for a smooth descent, achieving directional air-to-air throwing and ensuring strike accuracy. After the UAV countermeasure device 2 is thrown, the control system delays for a preset time to match the duration of the countermeasure device's free fall along the guide channel, and sends a reverse rotation command to the small servo motor 401. The small servo motor 401 rotates in the opposite direction, driving the front support rack 501 and the rear support rack 601 to move in the opposite direction through the connecting shaft 402 and gear 403, thereby pushing the front support 503 and the rear support 602 to unfold outward and return to the initial maximum spacing state. At this time, the pressure sensor at the bottom of the front support 503 is once again in a state of waiting to bear pressure, and the support returns to the take-off and landing support mode, providing a stable platform for the UAV carrier to return and land.
