Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a parabolic box. Furthermore, this invention also relates to a UAV spike-throwing device and method. Background Technology

[0002] In special tactical scenarios such as border standoffs and counter-terrorism operations, the rapid deployment of spiked obstacle groups is a key means of delaying enemy actions and ensuring regional security.

[0003] Traditional ground-based deployment methods typically rely on explosives or high-pressure pneumatic devices. The high-decibel noise generated during these operations easily reveals operational intentions. Furthermore, the spikes, due to the instantaneous impact of the power source, are randomly distributed during deployment, making it difficult to form a uniformly covered obstacle group. Deployment methods cannot dynamically adjust the density and range of spike distribution according to mission requirements, resulting in a randomly scattered obstacle group after deployment, making it difficult to accurately cover the core area of ​​the target region. In addition, the loud noise generated during deployment can be misinterpreted by the enemy as a firearms attack, leading to escalation and significant tactical risks.

[0004] Therefore, developing new parabolic boxes and drone spike-dropping devices has significant practical implications for combat in special tactical scenarios. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a parabolic box that produces less noise when throwing spikes and can adjust the distribution density or range of the spikes according to actual needs.

[0006] Furthermore, the technical problem to be solved by the present invention is to provide a drone spike-throwing device that produces low noise during stinging and can adjust the distribution density or range of the stings according to actual needs.

[0007] Furthermore, the technical problem to be solved by the present invention is to provide a method for scattering spikes using a drone spike scattering device. This method for scattering spikes produces less noise and allows for adjustment of the distribution density or range of the scattered spikes according to actual needs.

[0008] To solve the above-mentioned technical problems, the present invention provides a parabolic box, including a box body, baffles, opening and closing doors, and a driving mechanism. The box body is provided with a plurality of baffles to divide the box body into a plurality of receiving cavities. The bottom of the box body is rotatably connected to a plurality of opening and closing doors, which are used to seal a plurality of the receiving cavities. The driving mechanism is used to control the opening and closing angle of the corresponding opening and closing doors. The baffles can stop the object to be thrown during the opening and closing of the opening and closing doors.

[0009] Preferably, the top of the housing is detachably fitted with a top cover.

[0010] Specifically, the inner surface of the opening and closing door is provided with a lateral guide to guide the object to be thrown laterally.

[0011] Preferably, it further includes a guide member driving mechanism, wherein the lateral guide member is a V-shaped guide member with an adjustable included angle, and the guide member driving mechanism is used to adjust the included angle of the V-shaped guide member.

[0012] Specifically, the driving mechanism includes an electric cylinder and a linkage mechanism. The electric cylinder is connected to the opening and closing door through the linkage mechanism. The electric cylinder is used to drive the linkage mechanism to rotate, so as to drive the opening and closing door to rotate through the linkage mechanism.

[0013] Specifically, the opening and closing door includes a first opening and closing door and a second opening and closing door, both of which are hinged to the middle of the bottom surface of the box.

[0014] Based on the above-mentioned parabolic box technical solution, the present invention also provides a drone spike-throwing device, which includes a drone and a parabolic box of any of the above-mentioned technical solutions, wherein the parabolic box is disposed at the bottom of the drone.

[0015] Preferably, it also includes a height sensor for measuring the flight altitude of the drone and an angle sensor for measuring the opening angle of the door.

[0016] Based on the above-mentioned technical solution of the drone spike-throwing device, the present invention also provides a method for throwing spikes from the drone spike-throwing device, for controlling the throwing of spikes from any of the above-mentioned technical solutions, the method comprising the following steps: The remote-controlled drone spike-dispensing device flew to the target area; The opening angle of the door and / or the flight altitude of the UAV are controlled according to the target density distribution and / or the target lateral throwing distance. The spikes are stopped by the baffle, so that at least part of the spikes in the receiving cavity are thrown to the target area at the target lateral throwing distance to form the target density distribution.

[0017] Preferably, controlling the opening angle of each of the opening and closing doors and / or the flight altitude of the UAV based on the target density distribution and / or the target lateral throwing distance includes: The opening angle of the gate is adjusted according to the target lateral throwing distance and the target density distribution. The number of spikes thrown is controlled by the baffle blocking the spikes. The included angle of the lateral guide is adjusted according to the target lateral throwing distance so that the spikes not blocked by the baffle are thrown into the target area at the target lateral throwing distance to form the target density distribution.

[0018] Through the above technical solution, the parabolic box of this application has multiple receiving cavities divided by multiple baffles inside the box. Multiple objects to be thrown can be placed horizontally in each cavity. A hinged door is connected to the bottom of the box. When closed, the door seals multiple receiving cavities. The door is equipped with a drive mechanism to adjust its opening angle. During the opening process, spikes in the receiving cavities furthest from the hinge axis between the door and the box are thrown out first. Spikes in the receiving cavities relatively close to the hinge axis are not thrown out due to the cooperation of the door and baffles. As the opening angle of the door gradually increases, the baffles gradually become unable to stop the spikes in the corresponding receiving cavities, causing the spikes in each receiving cavity to be thrown out sequentially. Therefore, the parabolic box of this application can control the number of spikes thrown out by adjusting the opening angle of the door. After the door is opened, the spikes slide down the inner surface of the door. By adjusting the opening angle of the door, the initial horizontal velocity of the spikes as they slide down the inner surface of the door can be changed. Thus, the parabolic box of this application can change the range of spike scattering by changing the opening angle of the door. Attached Figure Description

[0027] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0028] like Figure 2 As shown, the parabolic box of this application includes a box body 1, baffles 2, opening and closing doors 3, and a drive mechanism 5. A row of baffles 2 is spaced apart inside the box body 1 to divide the box body 1 into several receiving cavities 4. Several opening and closing doors 3 are rotatably connected to the bottom of the box body 1. Each opening and closing door 3 corresponds to and seals multiple receiving cavities 4. Each opening and closing door 3 is correspondingly provided with a drive mechanism 5, so that the opening and closing angle of the corresponding opening and closing door 3 can be controlled by the drive mechanism 5. Figure 7 As shown, the opening and closing door 3 and the baffle 2 are configured such that the baffle 2 can stop the object to be thrown during the opening and closing of the door 3. Therefore, when the projectile box of this application throws the spikes 13, the opening angle of the opening and closing door 3 can be controlled by the drive mechanism 5. This allows a portion of the spikes 13 in the receiving cavity 4, which is far from the hinge axis between the opening and closing door 3 and the box body 1, to slide out along the inner surface of the opening and closing door 3, thus scattering the spikes 13. The spikes 13 in the other receiving cavity 4 cannot slide downwards due to the stop of the baffle 2, thereby controlling the number of spikes 13 thrown. After the opening and closing door 3 is opened to a certain angle, some of the spikes 13 in the receiving cavity 4 can slide downwards along the inner surface of the opening and closing door 3. By controlling the opening angle of the opening and closing door 3, the lateral initial velocity of the spikes 13 when thrown from the opening and closing door 3 can be adjusted, thereby adjusting the throwing range of the spikes 13.

[0029] As a preferred implementation method, such as Figure 1As shown, the top of the box 1 is detachably equipped with an upper cover plate 6. When filling the spikes 13, the upper cover plate 6 can be removed and the spikes can be filled directly, which is relatively simple. In some specific embodiments, the upper cover plate 6 is detachably installed on the top of the box 1 via a buckle 10.

[0030] As a specific implementation method, such as Figure 3 As shown, a transverse guide 7 is provided on the inner surface of the opening and closing door 3. The spike 13 first slides down along the inner surface of the opening and closing door 3, and then slides to both sides along the transverse guide 7, thus scattering the spikes.

[0031] In a preferred embodiment, the parabolic crater also includes a guide drive mechanism. The lateral guide 7 is a V-shaped guide with an adjustable included angle. The guide drive mechanism is used to adjust the included angle of the V-shaped guide. This embodiment can adjust the included angle of the V-shaped guide through the guide drive mechanism, thereby changing the tilt angle of the two sides of the V-shaped guide, and thus adjusting the lateral initial velocity of the spikes 13 sliding along the V-shaped guide. In this embodiment, the parabolic crater adjusts the number of spikes 13 thrown by adjusting the opening and closing angle of the opening and closing gate 3, and then adjusts the included angle of the V-shaped guide according to the opening and closing angle of the opening and closing gate 3 to control the lateral initial velocity of the spikes 13. This embodiment of the parabolic crater can more freely adjust the number of spikes thrown and the lateral initial velocity to form the required distribution density and range.

[0032] As a specific implementation method, such as Figure 1 As shown, the drive mechanism 5 includes an electric cylinder 501 and a linkage mechanism 502. The electric cylinder 501 is connected to the opening / closing door 3 via the linkage mechanism 502. The electric cylinder 501 drives the linkage mechanism 502 to rotate, thereby driving the opening / closing door 3 to rotate via the linkage mechanism 502. Figure 2 As shown, after the main rod of the electric cylinder 501 extends, it drives the opening and closing door 3 to rotate around the hinge axis between itself and the housing 1 through the linkage mechanism 502. The opening and closing angle of the opening and closing door 3 is controlled by controlling the extension and retraction length of the main rod of the electric cylinder.

[0033] In one specific implementation, multiple hinged doors 3 can be connected to the bottom of the box body 1. The openings of the multiple hinged doors 3 are not arranged opposite each other to avoid mutual interference when different doors 3 throw out the spikes 13. In some specific embodiments, such as Figure 2 As shown, the opening and closing door 3 includes a first opening and closing door 301 and a second opening and closing door 302, both of which are hinged to the middle of the bottom surface of the box body 1.

[0034] Based on the parabolic box mentioned in the above technical solution of the present invention, the present invention also provides a drone spike throwing device, which includes a drone 8 and the parabolic box mentioned above in this application, with the parabolic box disposed at the bottom of the drone 8.

[0035] As a preferred implementation method, such as Figure 1 as well as Figures 4 to 7 As shown, the parabolic box and the drone 8 are detachably connected. When loading the spikes 13, the parabolic box can be removed from the drone 8, and then the top cover plate 6 of the parabolic box can be removed to load the spikes 8, which is quite convenient. In one specific implementation, the drone 8 and the parabolic box are connected by a quick-release assembly 9. Specifically, the drone 8 can be detachably connected to the parabolic box through a bidirectional spring structure. The drone 8 forms a mounting plate 11, and an electromagnetic locking groove 902 and a positioning pin hole 903 are positioned on the mounting plate 11. The positioning pin hole 903 is located on both sides of the electromagnetic locking groove 902. A bidirectional spring lock structure 901 and a pin are provided on the upper part of the parabolic box. After the pin is installed corresponding to the positioning pin hole 902, the drone 8 and the parabolic box are fixed by electromagnetically locking the bidirectional spring lock structure 901.

[0036] As a specific implementation method, such as Figure 4 As shown, the bottom of the drone 8 has a shock-absorbing foot 12. The shock-absorbing foot 12 can adopt a silicone-spring composite structure (damping coefficient 0.8N·s / m), which can reduce the vibration amplitude of the drone flight by ≥60% and ensure the stacking stability of the spikes 8 during the throwing process.

[0037] In one preferred embodiment, the drone spike-throwing device further includes an altitude sensor for measuring the flight altitude of the drone 8 and an angle sensor for measuring the opening angle of the gate 3, so as to calculate the lateral throwing distance using the flight altitude and the opening angle. In some specific embodiments, a "V"-shaped guide is provided on the inner surface of the gate 3, and an angle sensor for the guide is provided to measure the tilt angle of the "V"-shaped guide, so as to calculate the lateral throwing distance of the spikes 13 in conjunction with the flight altitude and the opening angle of the gate 3.

[0038] Based on the UAV spike-throwing device mentioned in the above technical solution of the present invention, the present invention also provides a method for throwing spikes using the UAV spike-throwing device, which includes the following steps: The remote-controlled drone spike-dispensing device flew to the target area; The opening angle of the door 3 and / or the flight altitude of the drone 7 are controlled according to the target density distribution and / or the target lateral throwing distance. The baffle 2 stops the spikes 13, so that at least part of the spikes 13 in the receiving cavity 4 are thrown to the target area at the target lateral throwing distance to form the target density distribution.

[0039] This scattering method changes the initial lateral velocity and the number of spikes 13 scattered by adjusting the opening angle of the gate 3, and changes the scattering height of the spikes 13 by adjusting the flight altitude of the drone 8. In this way, the lateral scattering distance of the spikes 13 is changed by changing the initial lateral velocity and / or scattering height of the spikes 13, thus forming a specific density distribution.

[0040] In a preferred embodiment, controlling the opening angle of each door 3 and / or the flight altitude of the drone 8 based on the target density distribution and / or the target lateral throwing distance includes: The opening angle of the gate 3 is adjusted according to the target lateral throwing distance and target density distribution, that is, the opening angle of the gate 3 is adjusted according to the target throwing quantity. The number of spikes 13 thrown is controlled by the baffle 2 blocking the spikes 13. The angle of the lateral guide 7 is adjusted according to the target lateral throwing distance and the opening angle of the gate 3, so that the spikes 13 not blocked by the baffle 2 are thrown out with the target lateral throwing initial velocity. The flight altitude of the drone 8 is adjusted according to the target lateral throwing distance, so that the spikes 13 are thrown into the target area at the target lateral throwing distance to form the target density distribution.

[0041] As can be seen from the above description, the advantages of this application are as follows: First, the number of spikes thrown can be controlled by the combination of the opening and closing door and the baffle; second, the lateral guide can change the initial lateral throwing velocity of the spikes, which is conducive to forming a target density distribution; third, the top cover of the parabolic box is detachable, which is conducive to the loading of spikes.

[0042] The preferred embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this application, various simple modifications can be made to the technical solution of this application, and these simple modifications all fall within the protection scope of this application.

[0043] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, this application will not describe the various possible combinations separately.

[0044] Furthermore, various different implementations of this application can be combined in any way, as long as they do not violate the spirit of this application, they should also be regarded as the content disclosed in this application.
