Description

Technical Field

[0001] This application relates to the field of drone emergency communication equipment mounting technology, specifically a drone emergency communication equipment mounting shock absorption device. Background Technology

[0002] Emergency communication equipment mounting on drones refers to the technical means of rapidly restoring or enhancing communication capabilities in and around the scene of natural disasters, accidents, or public safety incidents by carrying dedicated communication equipment on a drone platform, thereby ensuring rescue command, information transmission, and contact with affected people.

[0003] When drones are used to mount emergency communication equipment, they are usually installed on the drone using a quick-fix method or locked to the fuselage with bolts and nuts. However, when a drone is in flight, it will tilt as the fuselage tilts, affecting the signal. In extreme weather, especially in windy conditions, even when the drone is hovering, the communication equipment will be blown by the wind, causing instability and signal instability, thus delaying emergency communications.

[0004] Therefore, this application provides a shock-absorbing device for mounting emergency communication equipment on unmanned aerial vehicles (UAVs) to solve the above-mentioned problems. Utility Model Content

[0005] This application provides a shock-absorbing device for mounting emergency communication equipment on unmanned aerial vehicles (UAVs), which aims to solve the problem mentioned in the background art that the existing UAVs use a fixed connection method for mounting emergency communication equipment, which is prone to shaking under stress in extreme weather, thus leading to unstable communication.

[0006] To achieve the above objectives, this application provides the following technical solution: a shock-absorbing device for mounting emergency communication equipment on a drone, comprising a drone chassis, a suspension plate suspended below the drone chassis, and a plurality of damping pads arranged in a circular array between the suspension plate and the drone chassis. The two ends of the damping pads are respectively fixedly connected to the drone chassis and the suspension plate. A stabilizing component is provided at the bottom of the suspension plate, the stabilizing component including a Z-axis motor fixedly mounted at the center of the bottom of the suspension plate, a Z-axis rocker arm fixedly connected to the output shaft of the Z-axis motor, and a rotatably connected to the Z-axis rocker arm. The system includes a Y-axis rocker arm at one end of the Z-axis rocker arm, a Y-axis motor fixedly mounted on the Z-axis rocker arm with its output shaft connected to the Y-axis rocker arm, an X-axis rocker arm rotatably connected to the other end of the Y-axis rocker arm, and an X-axis motor fixedly mounted on the Y-axis rocker arm with its output shaft connected to the X-axis rocker arm. A tilt sensor is fixedly mounted at the center of the top of the suspension plate. The output end of the tilt sensor, the input end of the Z-axis motor, the input end of the Y-axis motor, and the input end of the X-axis motor are all connected to the UAV controller. A positioning mechanism for fixing communication equipment is provided on the X-axis rocker arm. In this way, the damping pad and the three-axis stabilization system work together to effectively filter vertical vibration and horizontal sway, significantly improving the signal stability of the communication equipment. The three-axis motors are brushless servo motors, which can counteract the tilt of the UAV in real time, making them particularly suitable for complex environments such as strong winds.

[0007] Preferably, the positioning mechanism includes a pair of fixed clamps fixedly connected to one side of the X-axis rocker arm, a movable clamp telescopically connected to the side of the X-axis rocker arm away from the fixed clamps and moving closer to or away from the fixed clamps, and an adjusting screw rotatably connected to the fixed clamps and screwed to the movable clamps.

[0008] Preferably, the X-axis rocker arm is provided with a U-shaped fastener along its length for pressing the top of the communication device. Both ends of the U-shaped fastener penetrate the X-axis rocker arm, and both ends of the U-shaped fastener are screwed with lock nuts that contact the bottom surface of the X-axis rocker arm.

[0009] Preferably, the axes of the Z-axis motor, the Y-axis motor, and the X-axis motor are arranged in a three-axis configuration.

[0010] Preferably, the damping pad is made of carbon fiber reinforced polyurethane.

[0011] Preferably, the damping pad is inclined at a 45-degree angle to both the UAV chassis and the suspension plate.

[0012] This drone emergency communication device is equipped with a shock absorption device. Combining the passive shock absorption of the damping pad with the active adjustment of the three-axis motor, it effectively counteracts the drone's tilt and the equipment's sway caused by wind, ensuring that the communication device is always aligned with the target area and that the signal is stable. It can counteract the drone's tilt in real time and is especially suitable for complex environments such as strong winds.

[0013] The emergency communication equipment for this drone is equipped with a shock-absorbing device. The tilted installation changes the force direction of the damping pad from a single compression or tension to a composite deformation of shear and compression. The polyurethane material has higher damping efficiency during shear deformation, which can more effectively convert vibration energy into heat energy. The tilted installation disperses the stress at the connection point and avoids material fatigue or cracking caused by excessive local stress when installed vertically. Attached Figure Description

[0016] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0017] This embodiment provides a shock absorption device for mounting emergency communication equipment on a drone, such as... Figures 1-2As shown, the drone emergency communication equipment is equipped with a shock absorption device, including a drone base frame 1, a suspension plate 2 suspended below the drone base frame 1, and several damping pads 3 arranged in a circular array between the suspension plate 2 and the drone base frame 1. The two ends of the damping pads 3 are fixedly connected to the drone base frame 1 and the suspension plate 2, respectively. A stabilizing component 4 is provided at the bottom of the suspension plate 2. The stabilizing component 4 includes a Z-axis motor 41 fixedly installed at the center of the bottom of the suspension plate 2, a Z-axis rocker arm 42 fixedly connected to the output shaft of the Z-axis motor 41, a Y-axis rocker arm 43 rotatably connected to the other end of the Z-axis rocker arm 42, and a fixed... A Y-axis motor 44 is fixedly mounted on the Z-axis rocker arm 42 and its output shaft is connected to the Y-axis rocker arm 43. An X-axis rocker arm 45 is rotatably connected to the other end of the Y-axis rocker arm 43. An X-axis motor 46 is fixedly mounted on the Y-axis rocker arm 43 and its output shaft is connected to the X-axis rocker arm 45. A tilt sensor 47 is fixedly mounted at the top center of the suspension plate 2. The output end of the tilt sensor 47, the input end of the Z-axis motor 41, the input end of the Y-axis motor 44, and the input end of the X-axis motor 46 are all connected to the controller of the UAV. A positioning mechanism 5 for fixing communication equipment is provided on the X-axis rocker arm 45.

[0018] In use, the damping pad 3 is a passive shock absorption element that absorbs high-frequency vibrations caused by drone flight or wind, reducing the direct impact of physical vibrations on the communication equipment on the suspension plate 2. The stabilization component 4 includes a three-degree-of-freedom adjustment system of Z-axis, Y-axis, and X-axis. The Z-axis motor 41 is fixed to the bottom center of the suspension plate 2 and drives the Z-axis rocker arm 42 to rotate around the vertical axis. The Y-axis motor 44 is installed at the end of the Z-axis rocker arm 42 and drives the Y-axis rocker arm 43 to rotate around the horizontal axis (pitch direction). The X-axis motor 46 is installed at the end of the Y-axis rocker arm 43 and drives the X-axis rocker arm 45 to rotate around another horizontal axis (roll direction). The tilt sensor 47 monitors the tilt angle of the suspension plate 2 in real time and feeds the data back to the drone controller. Then, the controller controls the rotation of the Z-axis, Y-axis, and X-axis motors synchronously according to the deviation signal. The attitude of the suspension plate 2 is adjusted through the rocker arm linkage to keep it level. The positioning mechanism 5 is fixed to the end of the X-axis rocker arm 45 to firmly clamp or bolt the communication equipment to prevent displacement during the adjustment process.

[0019] Specifically, the positioning mechanism 5 includes a pair of fixed clamps 51 fixedly connected to one side of the X-axis rocker arm 45, a movable clamp 52 telescopically connected to the side of the X-axis rocker arm 45 away from the fixed clamps 51 and moving closer to or away from the fixed clamps 51, and an adjusting screw 53 rotatably connected to the fixed clamps 51 and screwed to the movable clamp 52; when the adjusting screw 53 is rotated, the threaded transmission drives the movable clamp 52 to move closer to or away from the fixed clamps 51 along the X-axis direction, realizing the clamping or release of communication devices of different widths. The clamping can be completed by manually rotating the screw, without the need for complicated tools, thus improving the deployment efficiency in emergency scenarios.

[0020] Furthermore, the X-axis rocker arm 45 is provided with a U-shaped fastener 54 along its length for pressing the top of the communication device. Both ends of the U-shaped fastener 54 pass through the X-axis rocker arm 45, and both ends of the U-shaped fastener 54 are screwed with lock nuts 541 that contact the bottom surface of the X-axis rocker arm 45. After the communication device is placed on the X-axis rocker arm 45, the U-shaped fastener 54 wraps around the device from the top, and tightening the lock nuts 541 makes the fastener press down on the top of the device to prevent it from sliding or jumping in the Z-axis direction.

[0021] Understandably, the axes of Z-axis motor 41, Y-axis motor 44 and X-axis motor 46 are set in a three-axis configuration; the axes of the three motors correspond to the three orthogonal directions of vertical (Z-axis), pitch (Y-axis) and roll (X-axis), forming three degrees of freedom for independent control.

[0022] More specifically, the damping pad 3 is made of carbon fiber reinforced polyurethane. Carbon fiber provides high strength and rigidity, preventing the damping pad 3 from deforming excessively or failing under stress. Polyurethane has excellent damping performance, which can effectively absorb high-frequency vibration energy and convert it into heat dissipation. It has the advantages of high-efficiency shock absorption, weather resistance and lightweight.

[0023] Furthermore, the damping pad 3 is tilted at a 45-degree angle to both the drone base frame 1 and the suspension plate 2. The tilted installation changes the force direction of the damping pad 3 from a single compression or tension to a composite deformation of shear and compression. Polyurethane material has higher damping efficiency during shear deformation and can more effectively convert vibration energy into heat energy. The tilted installation disperses the stress at the connection point and avoids material fatigue or cracking caused by excessive local stress when installed vertically.

[0024] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
