Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a UAV recovery device. Background Technology

[0002] Unmanned aerial vehicles (UAVs), also known as drones, are aircraft that do not require a pilot to operate. They fly through remote control systems, autonomous flight programs, or a combination of both. They typically consist of an airframe, a power system, a navigation system, a control system, and a mission payload. Based on their application scenarios, they can be divided into consumer-grade, industrial-grade, and military-grade types. In terms of their functions, UAVs have been widely penetrated into many fields due to their flexibility, maneuverability, and ability to enter high-risk or inaccessible areas.

[0003] A drone recovery device is a specialized piece of equipment for the precise capture and safe recovery of drones. It uses an deployed interception net to intercept drones in flight, causing them to collide with the net and thus achieving the purpose of recovery. At the same time, the interception net can convert the kinetic energy of the drone when it hits the net into internal energy or elastic potential energy, which greatly reduces the damage to the airframe and onboard precision equipment caused by impact overload.

[0004] Considering that existing drone recovery devices typically use interception nets for interception and recovery, if the elasticity of the net is too great, the elastic deformation generated upon impact will produce a reaction force on the drone after it has stopped, which can easily cause damage to the drone and displacement of the recovery position. If the elasticity of the net is too small, it is difficult to provide a good buffer for the drone and the recovery device, thus reducing the effectiveness of the recovery device. Utility Model Content

[0005] The purpose of this invention is to provide a drone recovery device.

[0006] To achieve this objective, the present invention adopts the following technical solution: A drone recovery device is provided, including a support plate, casters, a recovery mechanism, and a stabilizing mechanism. The casters are fixedly installed on the support plate, the recovery mechanism is fixedly installed on the support plate, the recovery mechanism is used to intercept and recover the drone, and the stabilizing mechanism is used to stabilize the support plate. The recovery mechanism includes a mobile frame, an interception net, a buffer mechanism, and a backstop mechanism. The mobile frame is slidably mounted on a support plate, the interception net is fixedly mounted on the mobile frame, the buffer mechanism cushions the movement of the mobile frame, and the backstop mechanism limits its position. When the interception net is impacted by a drone, causing the mobile frame to move, the buffer mechanism offsets part of the impact force on the interception net, and the backstop mechanism limits the position of the mobile frame after it has moved, preventing the mobile frame from generating a reverse thrust on the drone by driving the interception net.

[0007] Furthermore, the recycling mechanism also includes a fixed frame and two protective nets. The fixed frame is fixedly installed on the support plate, and the fixed frame is hinged to the movable frame through movable plate one and movable plate two in sequence. One end of each of the two protective nets is fixedly installed on the fixed frame, and the other end of each of the two protective nets is fixedly installed on the movable frame.

[0008] Furthermore, the recycling mechanism also includes two buffer pads, one of which is fixedly installed on movable plate one, and the other of which is fixedly installed on movable plate two.

[0009] Furthermore, the buffer mechanism includes a fixed shell, a fixed column, and a compression block. The fixed shell is fixedly installed on the fixed frame, the fixed column is fixedly installed on the movable frame, and the compression block is slidably installed on the fixed shell via a cylindrical rod. The compression block and the fixed column are hinged together by a connecting rod, and the compression block and the fixed shell are connected by a buffer spring. When the movable frame moves, the compression block compresses the buffer spring, which in turn causes the buffer spring to generate a reaction force on the compression block, thereby providing a buffering effect on the movable frame and the interception net.

[0010] Furthermore, the check mechanism includes a mounting block, a pull rod, and a wedge. The mounting block is fixedly mounted on the movable frame, and a slot is provided on the support plate. The wedge is slidably mounted on the mounting block and is driven by a spring to engage with the slot. The pull rod is fixedly mounted on the wedge and passes through the mounting block. The movement of the movable frame causes the wedge to move and engage with the slots at different positions, thus providing a unidirectional limiting effect on the movable frame.

[0011] Furthermore, the stabilizing mechanism includes an abutment plate and a movable block. The abutment plate is slidably mounted on the support plate via a guide rod, and the movable block is slidably mounted on the support plate. The movable block and the guide rod are hinged together via a hinge plate.

[0012] Furthermore, the stabilizing mechanism also includes a bidirectional threaded rod and a support block. The support block is fixedly installed on the support plate, and the bidirectional threaded rod is rotatably installed on the support block. The bidirectional threaded rod is threadedly connected to the moving block.

[0013] Furthermore, the stabilizing mechanism also includes an anti-slip pad, which is fixedly installed at the bottom of the abutment plate. The movement of the abutment plate causes the anti-slip pad to come into contact with the ground, thereby increasing the contact area and friction between the support plate and the ground, and improving the stability of the support plate.

[0014] The beneficial effects of this utility model are as follows: This drone recovery device, through its recovery mechanism, enables the moving frame to move after the interception net is impacted by the drone. A buffer mechanism offsets part of the impact force on the interception net, while a check mechanism limits the moving frame to prevent reverse thrust on the drone, thereby improving the effectiveness of the recovery device. Furthermore, the stabilizing mechanism increases the contact area and friction between the support plate and the ground, thus improving the stability of the support plate and preventing the impact of the drone on the interception net from causing the support plate to shift or tip over, further enhancing the effectiveness of the recovery device.

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of this utility model, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0020] Reference Figure 1 and Figure 2 The drone recovery device shown includes a support plate 1, casters 2, a recovery mechanism 3, and a stabilizing mechanism 4. The casters 2 are fixedly installed on the support plate 1 and have a self-locking function. The casters 2 facilitate the movement of the support plate 1. The recovery mechanism 3 is fixedly installed on the support plate 1 and is used to intercept and recover the drone, while improving the buffering effect and recovery efficiency of the drone. The stabilizing mechanism 4 is used to stabilize the support plate 1, thereby preventing the support plate 1 from shifting or tipping over. The recovery mechanism 3 includes a movable frame 32, an interception net 34, a buffer mechanism 38, and a backstop mechanism 39. The movable frame 32 is slidably mounted on the support plate 1. When the interception net 34 is hit by a drone, it will drive the movable frame 32 to move. The interception net 34 is fixedly mounted on the movable frame 32. The interception net 34 is used to intercept drones. The buffer mechanism 38 is used to buffer the movable frame 32, thereby reducing the impact force on the interception net 34 and providing buffer protection for both the drone and the interception net 34. The backstop mechanism 39 is used to limit the movable frame 32, thereby keeping the movable frame 32 in a fixed position and preventing the movable frame 32 from being subjected to elastic force, which would cause the interception net 34 to generate a reverse thrust on the drone.

[0021] Reference Figures 2 to 4The recovery mechanism 3 also includes a fixed frame 31 and two protective nets 33. The fixed frame 31 is fixedly installed on the support plate 1, and the fixed frame 31 is hinged to the movable frame 32 through movable plate 1 35 and movable plate 2 36 in sequence. When the movable frame 32 moves, it will drive movable plate 1 35 and movable plate 2 36 to move, thereby changing the angle between movable plate 1 35 and movable plate 2 36, which is used to support the intercepted drone. One end of each of the two protective nets 33 is fixedly installed on the fixed frame 31, and the other end of each of the two protective nets 33 is fixedly installed on the movable frame 32. The movement of the movable frame 32 will cause the protective nets 33 to tighten or loosen. The protective nets 33 are used to protect the drone and prevent the drone from falling between the fixed frame 31 and the movable frame 32. The recovery mechanism 3 also includes two buffer pads 37. One buffer pad 37 is fixedly installed on the first movable plate 35, and the other buffer pad 37 is fixedly installed on the second movable plate 36. The buffer pads 37 are used to provide cushioning protection when the drone falls on the first movable plate 35 and the second movable plate 36.

[0022] Reference Figure 5 and Figure 6 The buffer mechanism 38 includes a fixed shell 381, a fixed column 383, and a pressing block 384. The fixed shell 381 is fixedly installed on the fixed frame 31, and the fixed column 383 is fixedly installed on the movable frame 32. The movable frame 32 can move the fixed column 383. The pressing block 384 is slidably installed on the fixed shell 381 through a cylindrical rod 385, and the pressing block 384 and the fixed column 383 are hinged through a connecting rod 382. The fixed column 383 can move the connecting rod 382, ​​thereby moving the pressing block 384 along the cylindrical rod 385. The pressing block 384 and the fixed shell 381 are connected by a buffer spring 386. When the connecting rod 382 moves the pressing block 384, it will compress the buffer spring 386. Through the elastic force of the buffer spring 386, a reverse force will be generated on the pressing block 384, thereby buffering the movable frame 32 and the interception net 34.

[0023] Reference Figures 7 to 9The check mechanism 39 includes a mounting block 391, a pull rod 392, and a wedge 394. The mounting block 391 is fixedly mounted on the movable frame 32. The support plate 1 has a slot 395. Multiple slots 395 are provided. When the wedge 394 engages with slots 395 at different positions, it will limit the movable frame 32 at different positions. The wedge 394 is slidably mounted on the mounting block 391 and is driven by a spring 393 to engage with slots 395. The elastic force of the spring 393 drives the wedge 394 to engage with slots 395, thereby limiting the movable frame 32 in one direction. The pull rod 392 is fixedly mounted on the wedge 394 and passes through the mounting block 391. By pulling the pull rod 392, the wedge 394 can be moved, thereby releasing the wedge 394 from the engagement with slots 395.

[0024] Reference Figure 9 and Figure 10 The stabilizing mechanism 4 includes an abutment plate 41 and a movable block 45. The abutment plate 41 is slidably mounted on the support plate 1 via a guide rod 43. The distance between the abutment plate 41 and the ground can be adjusted by the movement of the abutment plate 41. The movable block 45 is slidably mounted on the support plate 1, and the movable block 45 is hinged to the guide rod 43 via a hinge plate 44. The movement of the movable block 45 can drive the hinge plate 44 to move, thereby driving the guide rod 43 to move, and then driving the abutment plate 41 to move.

[0025] Reference Figures 9 to 11 The stabilizing mechanism 4 also includes a bidirectional threaded rod 46 and a support block 47. The support block 47 is fixedly installed on the support plate 1 and supports the bidirectional threaded rod 46. The bidirectional threaded rod 46 is rotatably installed on the support block 47 and is threadedly connected to the movable block 45. The rotation of the bidirectional threaded rod 46 can drive the movable block 45 to move. The stabilizing mechanism 4 also includes an anti-slip pad 42, which is fixedly installed on the bottom of the abutment plate 41. When the abutment plate 41 moves, it can drive the anti-slip pad 42 to contact the ground, thereby increasing the contact area and friction between the support plate 1 and the ground, and thus improving the stability of the support plate 1.

[0026] Reference Figures 1 to 11 This drone recovery device, through its recovery mechanism, enables the moving frame to move after the interception net is impacted by a drone. A buffer mechanism offsets part of the impact force on the interception net, while a check mechanism limits the moving frame to prevent reverse thrust on the drone, thus improving the effectiveness of the recovery device. Furthermore, the stabilizing mechanism increases the contact area and friction between the support plate and the ground, enhancing the stability of the support plate and preventing the impact of the drone on the interception net from causing the support plate to shift or tip over, further improving the effectiveness of the recovery device.
