Abstract
Description
Technical Field
[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a surveying UAV that is easy to store. Background Technology
[0002] In fields such as geological exploration, topographic mapping, and urban planning, surveying drones have become important tools due to their high efficiency and accuracy.
[0003] A foldable surveying drone typically consists of a foldable fuselage, foldable propellers, a modular gimbal camera, a quick-locking mechanism, and an intelligent control system. The foldable fuselage is made of high-strength carbon fiber, making it lightweight and rigid. The foldable propellers are connected to the fuselage via a hinge structure and can be folded towards the fuselage, with a folded volume of only 1 / 3 of its unfolded state. The modular gimbal camera is connected to the fuselage with a snap-fit design, making it easy to disassemble and store separately. The quick-locking mechanism is used to secure the propellers and fuselage after folding, preventing loosening during transportation. The intelligent control system integrates attitude sensors and a folding status detection module to ensure the precise positioning of each component after unfolding.
[0004] However, the above-mentioned equipment has obvious shortcomings in use. The propellers and frames of traditional surveying drones are mostly rigidly fixed, which cannot be folded or have limited folding angles. In particular, the blades of multi-rotor drones are easily damaged by collisions, requiring special large storage boxes, which are inconvenient for field transportation. In view of this, we propose a surveying drone that is easy to store. Utility Model Content
[0005] The purpose of this invention is to provide a surveying drone that is easy to store, in order to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A folding mapping drone that is easy to store includes a frame, on which a mapping camera is fixedly mounted, and a folding assembly is provided on the frame, the folding assembly comprising:
[0008] A connecting frame is fixedly installed on the frame, an upper hinge frame is fixedly installed on the connecting frame, a lower hinge frame is fixedly installed on the connecting frame, a lower round tube is fixedly installed on the lower hinge frame, and an upper round tube is fixedly installed on the upper hinge frame.
[0009] Nut, a nut is fixedly installed on the upper hinge frame, a knob is rotatably installed on the lower hinge frame, a threaded rod is fixedly installed on the knob, a hinge plate is hingedly installed on the lower round tube and the upper round tube, and an installation bracket is fixedly installed on the hinge plate;
[0010] A high-speed motor is fixedly mounted on the mounting bracket. A small gear is fixedly mounted on the output end of the high-speed motor. A round rod is rotatably mounted on the mounting bracket. A transmission gear is fixedly mounted on the round rod. A power rod is fixedly mounted on the transmission gear. A propeller is fixedly mounted on the power rod.
[0011] In a further embodiment, multiple sets of the connecting frame, upper hinge frame, lower hinge frame, lower round tube, upper round tube, nut, knob, threaded rod, hinge plate, mounting frame, high-speed motor, pinion, round rod, transmission gear, power rod, and propeller are provided.
[0012] In a further embodiment, the upper hinge frame is positioned directly above the lower hinge frame, and the lower circular tube is positioned directly below the upper circular tube.
[0013] In a further embodiment, the pinion meshes with a transmission gear, and the threaded rod passes through the lower and upper round tubes and is threaded onto a nut.
[0014] In a further embodiment, a buffer assembly is provided on the connecting frame. The buffer assembly includes a cylinder. The cylinder is fixedly installed on the connecting frame. One end of a spring is fixedly installed inside the cylinder. A limit plate is fixedly installed on the other end of the spring. One end of a support rod is fixedly installed on the limit plate. A rubber block is fixedly installed on the other end of the support rod.
[0015] In a further embodiment, multiple sets of the cylinder, spring, limiting plate, support rod, and rubber block are provided.
[0016] In a further embodiment, the spring is disposed inside the cylinder, and the limiting plate slides inside the cylinder.
[0017] Compared with the prior art, this utility model provides a surveying drone that is easy to store, and has the following beneficial effects:
[0018] 1. This easily foldable surveying drone features a folding assembly to ensure structural stability during flight. This assembly is equipped with a rotary knob that drives a threaded rod through the lower and upper round tubes, connecting to the nut of the upper hinge frame. When the threaded rod is loosened, the upper and lower round tubes can be folded via the hinge plate, allowing the propeller to fit snugly against the frame. The folded size is reduced compared to the unfolded state, making it easier to carry and transport. When unfolded, the preload generated by tightening the threaded rod rigidly fixes the upper and lower hinge frames, and the small gear meshes with the transmission gear to ensure that there is no shaking when the high-speed motor drives the propeller to rotate.
[0019] 2. This easily stored surveying drone is equipped with a buffer component to reduce the damage rate during takeoff and landing. When the drone lands, this component, together with the rubber block, first contacts the ground. Then, the support rod pushes the limiting plate to compress the spring inside the cylinder, further converting the remaining impact force into elastic potential energy, thereby reducing the vibration amplitude of the frame. At the same time, the sliding guide of the limiting plate inside the cylinder ensures that the buffer force is transmitted vertically, preventing the fuselage from tilting and protecting the surveying camera from vibration damage.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Please see Figures 1-6 This utility model provides a technical solution:
[0030] A surveying drone that is easy to store includes a frame 1, on which a surveying camera 2 is fixedly mounted. The frame 1 serves as the main structure of the drone, and the surveying camera 2 fixed on it is used to perform surveying tasks.
[0031] In one embodiment of this utility model, a folding assembly 3 is provided on the frame 1. The folding assembly 3 includes a connecting frame 31. The connecting frame 31 is fixedly installed on the frame 1. An upper hinge frame 32 is fixedly installed on the connecting frame 31. A lower hinge frame 33 is fixedly installed on the connecting frame 31. A lower circular tube 34 is fixedly installed on the lower hinge frame 33. An upper circular tube 35 is fixedly installed on the upper hinge frame 32. A nut 36 is fixedly installed on the upper hinge frame 32. A knob 37 is rotatably installed on the lower hinge frame 33. A threaded rod 38 is fixedly installed on the knob 37. A hinge plate 39 is hingedly installed on the lower circular tube 34 and the upper circular tube 35. A mounting frame 310 is fixedly installed on the hinge plate 39. A high-speed motor 311 is fixedly installed on the mounting frame 310. A pinion 312 is fixedly installed at the output end of the high-speed motor 311. A round rod 313 is rotatably mounted on 310. A transmission gear 314 is fixedly mounted on the round rod 313. A power rod 315 is fixedly mounted on the transmission gear 314. A propeller 316 is fixedly mounted on the power rod 315. Multiple sets of connecting frame 31, upper hinge frame 32, lower hinge frame 33, lower round tube 34, upper round tube 35, nut 36, knob 37, threaded rod 38, hinge plate 39, mounting frame 310, high-speed motor 311, pinion 312, round rod 313, transmission gear 314, power rod 315 and propeller 316 are provided. The upper hinge frame 32 is located directly above the lower hinge frame 33. The lower round tube 34 is located directly below the upper round tube 35. The pinion 312 meshes with the transmission gear 314. The threaded rod 38 passes through the lower round tube 34 and the upper round tube 35 and is threaded onto the nut 36.
[0032] In this embodiment, when the drone needs to be stored, rotating the knob 37 loosens the threaded rod 38, and the upper round tube 35 and the lower round tube 34 can drive the mounting frame 310 to fold through the hinge plate 39, so that the propeller 316 fits against the frame 1. The volume after storage is greatly reduced compared to the unfolded state, making it easy to carry and transport. When the drone needs to fly, rotating the knob 37 tightens the threaded rod 38. The preload generated rigidly fixes the upper hinge frame 32 and the lower hinge frame 33. After the high-speed motor 311 on the mounting frame 310 is started, the pinion 312 at its output end meshes with the transmission gear 314 on the round rod 313, driving the power rod 315 and the propeller 316 to rotate, providing flight power for the drone. Moreover, this transmission structure ensures that there is no shaking when the high-speed motor 311 drives the propeller 316 to rotate, ensuring the structural stability during flight.
[0033] In one embodiment of this utility model, a buffer assembly 4 is provided on the connecting frame 31. The buffer assembly 4 includes a cylinder 41. The cylinder 41 is fixedly installed on the connecting frame 31. One end of a spring 42 is fixedly installed inside the cylinder 41. A limit plate 43 is fixedly installed on the other end of the spring 42. One end of a support rod 44 is fixedly installed on the limit plate 43. A rubber block 45 is fixedly installed on the other end of the support rod 44. Multiple sets of cylinder 41, spring 42, limit plate 43, support rod 44 and rubber block 45 are provided. The spring 42 is located inside the cylinder 41, and the limit plate 43 slides inside the cylinder 41.
[0034] In this embodiment, when the drone takes off and lands, the rubber block 45 first contacts the ground, and then the support rod 44 pushes the limiting plate 43 to slide inside the cylinder 41, compressing the spring 42. The spring 42 converts the impact force during takeoff and landing into elastic potential energy, thereby reducing the vibration amplitude of the frame 1. The sliding of the limiting plate 43 inside the cylinder 41 plays a guiding role, ensuring that the buffer force is transmitted vertically, avoiding the body tilting, protecting the mapping camera 2 from vibration damage, and reducing the damage rate of the drone during takeoff and landing.
[0035] In this application, all electrical components are electrically connected to the PLC controller and the power supply. The PLC controller is a conventional and known device that can control the surveying camera 2 and the high-speed motor 311.
