Abstract
Description
Technical Field
[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a UAV with a detachable radar device. Background Technology
[0002] Currently, drones are widely used in surveying, inspection, and security fields, and often need to be equipped with radar and other detection equipment to expand their functions. Traditional drone payloads are mostly fixedly installed, which means that the entire drone body needs to be disassembled for radar maintenance, replacement, or upgrades. This process is cumbersome and can easily damage delicate components.
[0003] While some detachable load structures in existing technologies are connected via snap-fit mechanisms, they lack a buffer protection mechanism. When drones land on complex terrain or encounter turbulent air currents, rigid connections can easily cause internal radar components to loosen or even be damaged. Furthermore, their lack of universal adaptability means that a single mounting structure cannot be compatible with radar equipment of different specifications, limiting application scenarios.
[0004] To address the aforementioned shortcomings, there is an urgent need for a detachable load radar device with rapid assembly and disassembly capabilities, multi-specification adaptability, and landing buffer protection, in order to improve the maintenance efficiency and equipment safety of UAV systems. Utility Model Content
[0005] The purpose of this utility model is to provide a detachable load radar device UAV that supports quick assembly and disassembly, is compatible with multiple radar specifications, and has landing buffer protection.

[0008] The frame has the flight controller fixedly installed inside, the propeller is mounted on the side, the camera is mounted at the front, and the landing support device is connected to the bottom.
[0009] The connecting device is located at the bottom of the frame;
[0010] The detachable load radar unit is detachably connected to the frame via a connecting device.
[0011] A buffer support assembly, located between the detachable load radar device and the connecting device, is used to absorb the landing impact force.
[0012] Furthermore, the connecting device includes connecting bolts and limiting holes, with the connecting bolts passing through the limiting holes to fix the connecting block to the frame.
[0013] Furthermore, the buffer support assembly includes several buffer support columns, and the buffer support columns are provided with limiting obstruction devices and buffer springs.
[0014] Furthermore, a buffer pad is provided at the bottom of the buffer support column.
[0015] Furthermore, the detachable load radar device has a mounting plate at its lower part, and multiple mounting holes are provided on the mounting plate.
[0016] Compared with the prior art, the present invention achieves the following beneficial technical effects:
[0017] This invention enables rapid assembly and disassembly of the load radar device through a detachable connection device, significantly shortening maintenance time; the buffer support structure, combined with springs and a limiting mechanism, effectively absorbs landing impacts and prevents damage to the radar equipment; the multi-hole mounting plate flexibly adapts to radars of different specifications, significantly improving the mission scalability and equipment reuse rate of UAVs, and comprehensively optimizing operational efficiency and device safety.

Detailed Implementation
[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0023] like Figure 1-2 As shown, this application provides a drone with a detachable radar payload, wherein:
[0024] The frame 1 serves as the main structure of the drone, housing the flight controller for flight control, a side-mounted propeller 2 for propulsion, a front-mounted camera 3 for aerial photography, and a landing support device 4 at the bottom to ensure landing stability. A connecting device 7 is located at the bottom of the frame 1, through which the load radar device 6 is detachably connected to the frame 1. A buffer support assembly is installed between the load radar device 6 and the connecting device 7 to absorb the impact energy during drone landing.
[0025] In this application, the specific structure of the connecting device 7 includes a connecting bolt 8 and a limiting hole 10. During assembly, the connecting bolt 8 passes through the limiting hole 10 to fasten the connecting block 9 to the bottom of the frame 1; when disassembling the load radar device 6, it is only necessary to loosen the connecting bolt 8 to disengage it from the limiting hole 10, thereby separating the connecting block 9 from the frame 1 and achieving quick maintenance.
[0026] In this application, the buffer support assembly consists of four buffer support columns 5, symmetrically distributed at the four corners of the load radar device 6. Each buffer support column 5 is equipped with a limiting obstruction device 11 and a buffer spring 12: the limiting obstruction device 11 is located in the middle section of the column and is used to limit the maximum compression stroke of the buffer spring 12; the two ends of the buffer spring 12 are respectively connected to the connecting block 9 and the mounting plate 14, and absorb the vertical impact force through elastic deformation.
[0027] In this application, a buffer pad 13 is added to the bottom of the buffer support column 5. The buffer pad 13 is made of silicone and is tightly attached to the contact interface between the buffer spring 12 and the mounting plate 14 to prevent the metal end of the spring from rigidly colliding with the mounting plate 14 and avoid structural damage.
[0028] In this application, the lower part of the load radar device 6 is fixed with a mounting plate 14, and the surface of the mounting plate 14 has multiple mounting holes 15 arranged in a matrix. By selecting mounting holes 15 at different positions to fix the bolts, radar detection equipment of different sizes and specifications can be installed, significantly improving the versatility of the device.
[0029] In this application, when the UAV lands, the impact force is transmitted to the frame 1 via the landing support device 4, and then acts on the buffer support assembly through the connecting device 7. The buffer spring 12 absorbs energy by deforming under pressure, the limiting device 11 prevents the spring from overloading and deforming, and the buffer pad 13 disperses local stress. This triple protection mechanism ensures that the load radar device 6 is not damaged by impact. When disassembly and maintenance are required, the load radar device 6 can be separated by loosening the connecting bolts 8, improving operational efficiency.
[0030] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
