Description

Technical Field

[0001] This application relates to the field of UAV surveying technology, specifically a UAV telescopic surveying support. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft controlled by radio remote control equipment and their own program control devices, or operated autonomously by an onboard computer, either completely or intermittently.

[0003] Currently, drones are widely used in surveying, aerial photography and other fields, but due to limitations in fuselage size and payload capacity, the installation space and stability of external equipment have become key issues.

[0004] Currently, the fixed brackets commonly found on the market cannot meet the installation requirements of different equipment and it is difficult to adjust the equipment position during flight. With the increasing demand for high-precision surveying, higher requirements are placed on the lightweight, adjustability and vibration resistance of the brackets. In order to solve the above problems, a UAV telescopic surveying bracket is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a retractable surveying support for unmanned aerial vehicles (UAVs), which can adapt to different equipment installation requirements and allows for adjustment of equipment position during flight, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: a telescopic surveying support for unmanned aerial vehicles (UAVs), comprising a UAV body and a telescopic support assembly. The telescopic support assembly includes a base and four standard mounting holes on the bottom surface of the UAV body. M6 bolts are installed at the four corners of the base. The base is installed on the bottom of the UAV body through the standard mounting holes and the M6 ​​bolts. A main arm is fixedly connected to the bottom surface of the base. A telescopic secondary arm is installed on the inner wall of the main arm. A prefabricated sleeve is fixedly connected to the top of the secondary arm. The two sides of the prefabricated sleeve are slidably fitted onto the two sides of the main arm. A detachable quick-release flange is installed at the bottom end of the secondary arm. A detachable surveying equipment body is installed at the bottom end of the quick-release flange.

[0007] The above solution utilizes standard mounting holes and M6 bolts to secure the base to the bottom of the UAV, ensuring overall stability of the bracket installation. An elastic damping layer flexibly buffers UAV vibrations, reducing resonance interference transmitted to the surveying equipment and improving data accuracy. The main and auxiliary arms are driven by servo motors to rotate lead screws, causing prefabricated sleeves to slide linearly along guide rods, enabling electric telescopic adjustment to meet dynamic position adjustments during flight. Quick-release flanges are locked to standard connection holes at the bottom of the auxiliary arms using embedded M4 screws, supporting rapid assembly and disassembly. The counterweights and servo motors are symmetrically arranged to balance the risk of load eccentricity. This solution combines lightweight design, high compatibility, and vibration resistance, significantly improving UAV surveying efficiency and data reliability.

[0008] Furthermore, an elastic damping layer is fixedly connected to the upper surface of the base, and the top of the elastic damping layer is in contact with the bottom surface of the UAV body.

[0009] Through the above scheme, the elastic damping layer, as a flexible buffer medium between the base and the UAV body, can absorb the vibration energy generated during flight, reduce the resonance transmitted to the mapping equipment body, and thus improve the accuracy of data acquisition.

[0010] Furthermore, the inner wall of the quick-release flange is fitted with four embedded M4 screws, and the bottom end of the auxiliary arm is provided with four standard connection holes. The quick-release flange is installed at the bottom end of the auxiliary arm through the embedded M4 screws and the standard connection holes.

[0011] The above solution, with its embedded M4 screws and standard connection holes, enables quick locking and separation of the quick-release flange and auxiliary arm, ensuring equipment installation stability while supporting equipment replacement in a short time.

[0012] Furthermore, a servo motor and a counterweight are fixedly connected to the bottom surface of the base, and the weights of the servo motor and the counterweight are consistent.

[0013] With the above scheme, the servo motor and the counterweight are symmetrically arranged at the bottom of the base. The inertial torque of the motor during operation is offset by the equal mass balancing design, which prevents the UAV body from losing its flight attitude due to load eccentricity.

[0014] Furthermore, a lead screw is fixedly connected to the output shaft end of the servo motor, a guide rod is fixedly connected to the bottom end of the counterweight, one side of the prefabricated sleeve is threaded to the outer surface of the lead screw, and the other side of the prefabricated sleeve is slidably sleeved on the outer surface of the guide rod.

[0015] The above scheme uses a servo motor to drive the lead screw to rotate, which in turn drives the prefabricated sleeve block to move linearly along the guide rod, thereby realizing the electric telescopic adjustment of the auxiliary arm and meeting the fine-tuning requirements of the equipment position during flight.

[0016] Furthermore, two support plates are fixedly connected to the bottom end of the main arm, the lead screw is rotatably sleeved in the inner wall of the corresponding support plate, and the guide rod is fixedly connected to the upper surface of the corresponding support plate.

[0017] With the above solution, the support plate serves as a fixed support structure for the lead screw and guide rod, ensuring the coaxiality and rigidity of the transmission system and avoiding jamming or wear caused by off-center load during the extension and retraction process.

[0018] Furthermore, two protrusions are fixedly connected to the inner wall of the main arm, and the two sides of the prefabricated sleeve are slidably sleeved on the outer surfaces of the two protrusions respectively.

[0019] Through the above scheme, the sliding cooperation between the protrusion and the prefabricated sleeve forms a dual guiding mechanism, which restricts the auxiliary arm to move only along the axial direction of the main arm, prevents radial displacement during the extension and retraction process, and improves structural stability.

[0020] Furthermore, landing gears are fixedly connected to both sides of the bottom surface of the drone body, and a buffer pad is fixedly connected to the bottom end of each landing gear.

[0021] The above solution uses a highly elastic silicone material to install a buffer pad at the end of the landing gear. When the UAV lands, the pad absorbs the impact energy through deformation, reducing the risk of damage to the surveying equipment due to ground vibration.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This retractable mapping bracket for UAVs is fixed to the base and the bottom of the UAV body via standard mounting holes and M6 bolts, ensuring the overall stability of the bracket installation. An elastic damping layer flexibly buffers the vibration of the UAV body, reducing resonance interference transmitted to the mapping equipment and improving data accuracy. The main arm and auxiliary arm are driven by servo motors to rotate lead screws, causing prefabricated blocks to slide linearly along guide rods, achieving electric telescopic adjustment to meet the dynamic adjustment needs of the equipment position during flight. Quick-release flanges are locked to the standard connection holes at the bottom of the auxiliary arm via embedded M4 screws, supporting rapid assembly and disassembly. The counterweights and servo motors are symmetrically arranged to balance the risk of load eccentricity. This solution combines lightweight design, high compatibility, and vibration resistance, significantly improving UAV mapping efficiency and data reliability. Attached Figure Description

[0031] 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.

[0032] Please see Figure 1 , Figure 3 and Figure 4 This embodiment provides a telescopic mapping support for a drone, comprising a drone body 1 and a telescopic support assembly 2. The telescopic support assembly 2 includes a base 201 and four standard mounting holes 202 formed on the bottom surface of the drone body 1. M6 bolts 203 are installed at each of the four corners of the base 201. The base 201 is installed on the bottom of the drone body 1 through the standard mounting holes 202 and the M6 ​​bolts 203. A main arm 205 is fixedly connected to the bottom surface of the base 201. A telescopic secondary arm 206 is installed on the inner wall of the main arm 205. A prefabricated sleeve block 207 is fixedly connected to the top of the secondary arm 206. The prefabricated sleeve 207 is slidably sleeved on both sides of the main arm 205. The bottom end of the auxiliary arm 206 is equipped with a detachable quick-release flange 208. The bottom end of the quick-release flange 208 is equipped with a detachable surveying equipment body 3. An elastic damping layer 204 is fixedly connected to the upper surface of the base 201. The top of the elastic damping layer 204 is in contact with the bottom surface of the UAV body 1. The elastic damping layer 204 serves as a flexible buffer medium between the base 201 and the UAV body 1, which can absorb the vibration energy generated during flight and reduce the resonance transmitted to the surveying equipment body 3, thereby improving the data acquisition accuracy.

[0033] Please see Figure 3 , Figure 4 and Figure 5 The inner wall of the quick-release flange 208 is fitted with four embedded M4 screws 209. The bottom end of the auxiliary arm 206 has four standard connection holes 210. The quick-release flange 208 is installed at the bottom end of the auxiliary arm 206 via the embedded M4 screws 209 and the standard connection holes 210. The design of the embedded M4 screws 209 and the standard connection holes 210 enables quick locking and separation of the quick-release flange 208 and the auxiliary arm 206, ensuring the stability of the equipment installation while supporting rapid equipment replacement. A servo motor 211 and a counterweight 213 are fixedly connected to the bottom surface of the base 201. The servo motor 211 and the counterweight 213 have the same weight. The counterweight 213 is symmetrically arranged at the bottom of the base 201. The equal mass balancing design counteracts the inertial torque during motor operation, preventing the UAV body 1 from becoming unbalanced due to load eccentricity. The output shaft of the servo motor 211 is fixedly connected to the lead screw 212, and the bottom end of the counterweight 213 is fixedly connected to the guide rod 214. One side of the prefabricated sleeve 207 is threaded to the outer surface of the lead screw 212, and the other side of the prefabricated sleeve 207 is slidably sleeved on the outer surface of the guide rod 214. The servo motor 211 drives the lead screw 212 to rotate, causing the prefabricated sleeve 207 to move linearly along the guide rod 214, realizing the electric telescopic adjustment of the auxiliary arm 206 and meeting the fine adjustment requirements of the equipment position during flight.

[0034] Please see Figure 1 , Figure 2 and Figure 5 Two support plates 215 are fixedly connected to the bottom end of the main boom 205. The lead screw 212 is rotatably sleeved in the inner wall of the corresponding support plate 215. The guide rod 214 is fixedly connected to the upper surface of the corresponding support plate 215. The support plate 215 serves as a fixed support structure for the lead screw 212 and the guide rod 214, ensuring the coaxiality and rigidity of the transmission system and preventing jamming or wear caused by uneven load during extension and retraction. Two protrusions 216 are fixedly connected to the inner wall of the main boom 205. The two sides of the prefabricated sleeve block 207 are slidably sleeved on the outer surface of the two protrusions 216 respectively. The sliding engagement of the protrusion 216 and the prefabricated sleeve 207 forms a dual guiding mechanism, which restricts the auxiliary arm 206 to move only along the axial direction of the main arm 205, prevents radial displacement during the extension and retraction process, and improves structural stability. Both sides of the bottom surface of the UAV body 1 are fixedly connected to the landing gear 4, and the bottom end of each landing gear 4 is fixedly connected to the buffer pad 5. The buffer pad 5 installed at the end of the landing gear 4 is made of high elastic silicone material, which absorbs the impact energy through deformation when the UAV body 1 lands, reducing the risk of damage to the surveying equipment body 3 caused by ground vibration.

[0035] In this embodiment, a telescopic mapping support for a UAV is fixedly connected to the base 201 and the bottom of the UAV body 1 via standard mounting holes 202 and M6 bolts 203, ensuring the overall installation stability of the support. An elastic damping layer 204 flexibly buffers the vibration of the UAV body 1, reducing resonance interference transmitted to the mapping equipment body 3 and improving data accuracy. The main arm 205 and auxiliary arm 206 are driven by a servo motor 211 to rotate the lead screw 212, causing the prefabricated sleeve 207 to slide linearly along the guide rod 214, achieving electric telescopic adjustment to meet the dynamic adjustment requirements of the equipment position during flight. A quick-release flange 208 is also included. The embedded M4 screw 209 is locked to the standard connection hole 210 at the bottom of the auxiliary arm 206, supporting quick disassembly and assembly. The counterweight 213 and servo motor 211 are symmetrically arranged to balance the risk of load eccentricity. The support plate 215 connects the lead screw 212 and the guide rod 214 to ensure coaxiality. Combined with the axial limit of the prefabricated sleeve block 207 by the protrusion 216, it ensures that there is no offset or jamming during the extension and retraction process. The buffer pad 5 at the end of the landing gear 4 is made of high elasticity silicone material to absorb the landing impact and reduce the probability of damage to the surveying equipment body 3. This solution combines lightweight, high compatibility and vibration resistance, significantly improving the efficiency and data reliability of UAV surveying.

[0036] The working principle of the above embodiment is as follows: The UAV body 1 is fixed to the bottom of the fuselage through the standard mounting holes 202 and M6 bolts 203 at the bottom of the base 201. The elastic damping layer 204 on the upper surface of the base 201 is in flexible contact with the UAV body 1. Through the material properties, it absorbs the vibration energy caused by the propeller and airflow during flight, reducing the resonance transmitted to the surveying equipment body 3. The main arm 205 and the auxiliary arm 206 constitute the core structure of the telescopic arm. After receiving the remote control command, the servo motor 211 drives the lead screw 212 to rotate. Through the threaded transmission, the prefabricated sleeve 207 slides linearly along the guide rod 214, realizing the electric telescopic adjustment of the auxiliary arm 206 during flight, meeting the surveying needs of different surveying equipment bodies 3. The counterweight 213 and the servo motor 211 are symmetrically arranged at the bottom of the base 201. The equal mass balance counteracts the inertial torque of the motor operation, ensuring that the motor is inertial and the torque is balanced. The human-machine body 1 maintains a stable flight attitude. The end of the auxiliary arm 206 is fixed with a quick-release flange 208 via an embedded M4 screw 209 and a standard connection hole 210, allowing for quick installation and replacement of surveying equipment bodies 3 of different sizes. The protrusion 216 on the inner wall of the main arm 205 and the sliding cooperation of the prefabricated sleeve block 207 form a dual guiding mechanism. Combined with the support plate 215 supporting the lead screw 212 and guide rod 214, it ensures no radial offset or jamming during the extension and retraction process. When the UAV lands, the buffer pad 5 at the end of the landing gear 4 absorbs the impact force upon landing through deformation. Before landing, it can retract the surveying equipment body 3, raising the height of the surveying equipment body 3 above the ground to a safe range and reducing the probability of accidental damage to the surveying equipment body 3. The entire system achieves stable mounting and efficient operation of high-precision surveying equipment in complex environments through lightweight structural design, adjustment and vibration resistance coordination.
