Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of remote sensing accessories for unmanned aerial vehicles (UAVs), and in particular to a mobile platform for remote sensing measurement of UAVs. Background Technology
[0002] Unmanned aerial vehicle (UAV) remote sensing technology is now widely used in fields such as topographic mapping, engineering monitoring, and agricultural surveys. It collects data through various remote sensing sensors mounted on the UAV platform. However, existing mobile UAV remote sensing platforms for engineering surveying have the following problems: during use, unexpected situations can cause the UAV to crash, resulting in the remote sensing device directly impacting the ground and causing damage.
[0003] In response, patent CN214138987 U discloses a mobile platform for remote sensing measurement using a drone for engineering surveying. By setting up a protective cover and a retractable sensor platform, the sensor can be retracted into the cover during a fall to avoid direct impact. However, it still has many obvious defects. Its protection mechanism relies solely on a return spring to achieve retraction, but the sensor and the platform are rigidly connected. During a fall, the huge impact acceleration will be transmitted to the sensor body without attenuation through the rigid structural path. The precision optical and electronic components inside will still be damaged by the severe impact. Moreover, the electric push rod, which is the core power component, is usually directly exposed on the outside of the platform. During long-term use, the push rod is prone to collision and scratch damage when the drone lands or is accidentally collided, causing the entire protection function to fail and affecting the service life.
[0004] Therefore, it is necessary to provide a new mobile platform for UAV remote sensing measurement to solve the above-mentioned technical problems. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a mobile platform for UAV remote sensing measurement.
[0006] The UAV remote sensing measurement mobile platform provided by this utility model includes: a connecting plate, a protective tube, an angle adjustment mechanism, a telescopic storage mechanism, a buffer mechanism, and a landing support mechanism. Two symmetrically arranged protective tubes are fixedly connected to the lower surface of the connecting plate. Two symmetrically arranged angle adjustment mechanisms are installed on the lower surface of the connecting plate, each located inside one of the two protective tubes. A telescopic storage mechanism is connected to each angle adjustment mechanism. The telescopic storage mechanism includes an electric push rod and a fixed plate. The electric push rod is installed on the angle adjustment mechanism, and its output end extends outside the protective tube and is fixedly connected to the fixed plate. A buffer mechanism is installed on the fixed plate. The buffer mechanism includes a telescopic rod, a polyurethane spring, an inverted L-shaped mounting plate, and a horizontal mounting plate. An inverted L-shaped mounting plate is fixedly connected to the upper surface of the fixed plate via two parallel telescopic rods. A polyurethane spring with damping characteristics is sleeved on the telescopic rod. A horizontal mounting plate is installed on one side of the inverted L-shaped mounting plate. Two symmetrically arranged landing support mechanisms are connected to the lower surface of the connecting plate.
[0007] Preferably, the connecting plate is provided with multiple connecting holes.
[0008] Preferably, a fixing ring is fixedly sleeved on the protective tube, and the fixing ring is fixedly connected to the lower surface of the connecting plate by a plurality of evenly distributed fixing bolts.
[0009] Preferably, the angle adjustment mechanism includes a servo motor, a rotating shaft, and a rotating plate. The servo motor is mounted on the lower surface of the connecting plate and is located inside the protective tube. The output end of the servo motor is fixedly connected to the rotating shaft via a coupling. The lower end of the rotating shaft is fixedly connected to the rotating plate, and an electric push rod is mounted on the lower surface of the rotating plate.

Both ends of the lifting rods are fixedly fitted with rubber sleeves.
[0014] Compared with related technologies, the UAV remote sensing measurement mobile platform provided by this utility model has the following beneficial effects: 1. This utility model provides a mobile platform for UAV remote sensing measurement. When the UAV lands or crashes accidentally, the electric push rod retracts, housing the remote sensing measurement device in a protective tube. The protective tube prevents the electric push rod and the remote sensing measurement device from being directly impacted, thus improving their service life. Secondly, for remote sensing measurement devices with precision optical and electronic components, an elastic damping system is formed by the telescopic rod and a polyurethane spring with damping characteristics. This system converts the kinetic energy of the impact into elastic potential energy and heat energy, thereby significantly reducing the peak impact force transmitted to the remote sensing measurement device. This prevents the remote sensing measurement device from being damaged by excessive impact during use, further improving its service life.
[0015] 2. This utility model provides a mobile platform for UAV remote sensing measurement. During use, the rotation of the servo motor can drive the rotation of the rotating plate through the rotating shaft, thereby adjusting the orientation of the remote sensing measurement device. This allows the UAV to complete the scan without overall turning, greatly improving the work efficiency and flight stability. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0019] Please refer to the following: Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 This is a structural schematic diagram of the present invention from another angle; Figure 3 This is a partial cross-sectional structural diagram of the present invention. It includes: a connecting plate 1, a protective tube 3, an angle adjustment mechanism, a telescopic storage mechanism, a buffer mechanism, and a lifting and lowering support mechanism.
[0020] refer to Figure 1 and Figure 2 As shown, two symmetrically arranged protective tubes 3 are fixedly connected to the lower surface of the connecting plate 1. Two symmetrically arranged angle adjustment mechanisms are installed on the lower surface of the connecting plate 1. The two angle adjustment mechanisms are located inside the two protective tubes 3 respectively. A telescopic storage mechanism is connected to the angle adjustment mechanism. The telescopic storage mechanism includes an electric push rod 7 and a fixed plate 8. The electric push rod 7 is installed on the angle adjustment mechanism. The output end of the electric push rod 7 extends to the outside of the protective tube 3 and is fixedly connected to the fixed plate 8. A buffer mechanism is installed on the fixed plate 8. The buffer mechanism includes a telescopic rod 9, a polyurethane spring 10, an inverted L-shaped mounting plate 11 and a horizontal mounting plate 13. The inverted L-shaped mounting plate 11 is fixedly connected to the upper surface of the fixed plate 8 through two parallel telescopic rods 9. A polyurethane spring 10 with damping characteristics is sleeved on the telescopic rod 9. A horizontal mounting plate 13 is installed on one side of the inverted L-shaped mounting plate 11. Two symmetrically arranged lifting and lowering support mechanisms are connected to the lower surface of the connecting plate 1.
[0021] It should be noted that: First, the remote sensing measurement device is installed on the inverted L-shaped mounting plate 11 and the horizontal mounting plate 13. The connecting plate 1 is connected to the mounting frame of the UAV. When in use, the electric push rod 7 is activated, and its output end extends downward. The output end of the electric push rod 7 moves downward through a buffer mechanism and the remote sensing measurement device on it, so that it moves smoothly out of the protective tube 3 to perform measurement. When the UAV lands or crashes accidentally, the electric push rod 7 retracts. The retraction action of the electric push rod 7 is controlled by the flight controller of the UAV (this is existing technology and will not be described in detail here). The remote sensing measurement device is housed in the protective tube 3. Through the protective effect of the protective tube 3, the electric push rod 7 and the remote sensing measurement device are prevented from being directly impacted. Second, for remote sensing measurement devices with precision optical and electronic components, an elastic damping system is formed by the telescopic rod 9 and the polyurethane spring 10 with damping characteristics to convert the kinetic energy of the impact into elastic potential energy and heat energy for dissipation.

[0023] refer to Figure 2 As shown, a fixing ring 5 is fixedly sleeved on the protective pipe 3. The fixing ring 5 is fixedly connected to the lower surface of the connecting plate 1 by a plurality of evenly distributed fixing bolts 6, so that the protective pipe 3 can be easily and quickly disassembled and assembled.
[0024] refer to Figure 3As shown, the angle adjustment mechanism includes a servo motor 15, a rotating shaft 16, and a rotating plate 4. The servo motor 15 is installed on the lower surface of the connecting plate 1. The servo motor 15 is located inside the protective tube 3. The output end of the servo motor 15 is fixedly connected to the rotating shaft 16 through a coupling. The lower end of the rotating shaft 16 is fixedly connected to the rotating plate 4. The electric push rod 7 is installed on the lower surface of the rotating plate 4.
[0025] It should be noted that during use, the rotation of the servo motor 15 can drive the rotation of the rotating plate 4 through the rotating shaft 16. The rotation of the servo motor 15 is controlled by the flight controller built into the UAV (this is existing technology and will not be elaborated here). This allows the orientation of the remote sensing measurement device to be adjusted, so that the UAV can complete the scan without overall turning.
[0026] refer to Figure 3 As shown, a conductive slip ring 17 is installed on the rotating shaft 16. The conductive slip ring 17 is a prior art technology and adopts the MMC235 series. The stator end of the conductive slip ring 17 is fixedly connected to the housing of the servo motor 15 through its own mounting bracket, and the rotor end is fixedly connected to the rotating shaft 16 and rotates synchronously with it. All cables are first connected to the stator end and then led out from the rotor end. With this structure, when the rotating shaft 16 drives the rotating plate 4 to rotate, the power and signal transmission is completed by the sliding contact piece inside the conductive slip ring 17, avoiding the tangling of external cables.
[0027] refer to Figure 2 As shown, the horizontal mounting plate 13 is provided with a first mounting hole 14, and the inverted L-shaped mounting plate 11 is provided with a plurality of second mounting holes 12. The first mounting hole 14 and the second mounting hole 12 facilitate the installation of the remote sensing measurement device on the horizontal mounting plate 13 and the inverted L-shaped mounting plate 11.
[0028] refer to Figure 1 and Figure 2 As shown, the lifting support mechanism includes a connecting seat 21, connecting bolts 22, connecting rods 18, lifting rods 19, and rubber sleeves 20. The lower surface of the connecting plate 1 is fixedly connected to the connecting seat 21 by two symmetrically arranged connecting bolts 22. The lower surface of the connecting seat 21 is fixedly connected to the lifting rods 19 by two symmetrically arranged connecting rods 18. Both ends of the lifting rods 19 are fixedly fitted with rubber sleeves 20.
[0029] It should be noted that during use, the landing support mechanism, consisting of the connecting seat 21, connecting bolt 22, connecting rod 18, landing rod 19 and rubber sleeve 20, plays a supporting role during the take-off and landing of the UAV, while the rubber sleeve 20 can play a certain cushioning role during take-off and landing.
[0030] The working principle of this utility model is as follows: First, the remote sensing measurement device is installed on the inverted L-shaped mounting plate 11 and the horizontal mounting plate 13. The connecting plate 1 is connected to the mounting frame of the UAV. When in use, the electric push rod 7 is activated, and its output end extends downward. The output end of the electric push rod 7 moves downward through a buffer mechanism and the remote sensing measurement device on it, so that it moves smoothly out of the protective tube 3 to perform measurement operations. When the UAV lands or crashes accidentally, the electric push rod 7 retracts. The retraction action of the electric push rod 7 is controlled by the flight controller on the UAV, which houses the remote sensing measurement device in the protective tube 3. Through the protective effect of the protective tube 3, the electric push rod 7 and the remote sensing measurement device are prevented from being directly impacted, thus improving the service life of the electric push rod 7 and the remote sensing measurement device. Second, for remote sensing measurement devices with precision optical and electronic components, the telescopic rod 9 and the polyurethane spring 10 with damping characteristics are used to... An elastic damping system is formed to convert the kinetic energy of the impact into elastic potential energy and heat energy, thereby significantly reducing the peak impact force transmitted to the remote sensing measurement device and preventing damage to the remote sensing measurement device due to excessive impact during use. This further improves the service life of the remote sensing measurement device. During use, the rotation of the servo motor 15 can drive the rotation of the rotating plate 4 through the rotating shaft 16. The rotation of the servo motor 15 is controlled by the flight controller on the UAV, which can adjust the orientation of the remote sensing measurement device, allowing the UAV to complete scanning without overall turning, greatly improving operational efficiency and flight stability. Moreover, the landing support mechanism composed of the connecting seat 21, connecting bolt 22, connecting rod 18, landing bar 19 and rubber sleeve 20 plays a supporting role during the take-off and landing of the UAV, while the rubber sleeve 20 can play a certain buffering role during take-off and landing.
