Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a UAV with a detachable anti-collision structure. Background Technology

[0002] Existing anti-collision structures on drones are typically fixed to the drone body through welding or one-piece injection molding, forming a frame-like or cage-like protection around the body. Their core advantage lies in their high structural strength, which can withstand relatively strong collision impacts. They are widely used in industrial-grade inspection drones. However, their fatal flaw is that they are not detachable. When the anti-collision frame is deformed or worn due to a collision, the entire body structure needs to be disassembled and repaired, which is not only time-consuming but also costly. Therefore, there is a need for a drone with a detachable anti-collision structure.

[0003] In existing drones, the built-in anti-collision structure is usually fixed to the drone body by welding or one-piece injection molding. When the anti-collision frame is deformed or worn due to a collision, the entire body structure needs to be disassembled and repaired. This not only has a long repair cycle but also high repair costs. The fixed structure height prevents the drone from adjusting its ground clearance according to the operation scenario. When taking off and landing in complex terrain, the bottom of the fuselage may be damaged due to being too close to the ground. In addition, the buffer structure is usually unidirectional, which has great limitations and cannot cope with complex impact scenarios. Therefore, there is an urgent need for a drone with a detachable anti-collision structure. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a drone with a detachable anti-collision structure to solve the problem that the existing anti-collision structure of drones is usually fixed to the drone body by welding or integral injection molding. When the anti-collision frame is deformed or worn due to collision, the entire body structure needs to be disassembled and repaired, which not only has a long maintenance cycle but also high maintenance costs. The fixed structure height makes it impossible for the drone to adjust the ground clearance according to the operation scenario. When taking off and landing in complex terrain, the bottom of the fuselage may be damaged due to being too close to the ground. In addition, the buffer structure is usually buffered in one direction, which has great limitations and cannot cope with complex impact scenarios.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drone with a detachable anti-collision structure, comprising a drone body, an adjustment compartment at the bottom of the drone body, a groove on the inner wall of the adjustment compartment, an adjustment rod installed inside the adjustment compartment, a positioning block on the side wall of the adjustment rod, bolt holes on the side walls of the adjustment compartment and the adjustment rod, a fixing bolt penetrating through the inner wall of the bolt hole, and a fixing nut threadedly connected to the outer wall of the fixing bolt.

[0006] A buffer block is provided at the bottom of the adjusting rod, a buffer frame is installed on the outside of the buffer block, a damper is fixedly connected to the inner wall of the buffer frame, a damping rod is installed inside the damper, and a buffer spring is installed on the outer wall of the damper.

[0007] Preferably, the adjusting rod forms a sliding structure with the adjusting chamber through the positioning block, and the positioning block is engaged with the sliding groove.

[0008] Preferably, the adjusting rod is sleeved with the adjusting chamber, and the adjusting rod is threadedly fixed to the adjusting chamber by a fixing bolt.

[0009] Preferably, the buffer block is formed into a telescopic structure with the buffer frame by a buffer spring, and the buffer block is set in a trapezoidal shape.

[0010] Preferably, the buffer spring is sleeved with the damping rod, and the surface of the damping rod is in close contact with the outer wall of the buffer block.

[0011] Preferably, the buffer block is movably connected to the buffer frame, and the top of the buffer frame is slotted.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the setting of an adjustment chamber, a slide, an adjustment rod, a positioning block, bolt holes, fixing bolts, and fixing nuts, allows for the replacement of the buffer frame at the bottom of the adjustment rod and the dampers, damping rods, and buffer springs inside the buffer frame during disassembly and reassembly, ensuring that it always has a good buffering effect and avoiding damage to the drone body due to buffer failure. By inserting the adjustment rod into the adjustment chamber and then fixing it with the fixing bolts and nuts, and by aligning the bolt holes on the adjustment rod with the bolt holes at different heights on the adjustment chamber, the height of the drone body above the ground can be adjusted, preventing the buffer frame from sinking into low places or being damaged by protrusions, ensuring the smooth take-off and landing of the drone. It not only realizes the convenient disassembly and assembly of the anti-collision buffer mechanism and reduces maintenance costs, but also improves the environmental adaptability of the drone through flexible height adjustment function, providing reliable safety guarantee for drone operations in different scenarios. 2. This utility model, through the setting of buffer blocks, buffer frames, dampers, damping rods, and buffer springs, ensures that when the drone lands on the ground, the drone is subjected to a reaction force, which drives the buffer block to move downwards and compresses the damping rods at the bottom and sides into the dampers. At the same time, it compresses the buffer springs. Then, the elasticity of the buffer springs and the dampers are used to buffer and release the reaction force, which can effectively reduce the impact of the ground reaction force on the drone. The trapezoidal buffer block converts the vertical impact into multi-directional component force. With the dampers and buffer springs at the bottom and sides, a 360° all-round buffer is formed, which can cope with complex impact scenarios and solves the limitations of traditional single-direction buffering.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0016] The embodiments of this utility model will be described below based on its overall structure.

[0017] Please see Figures 1-4A drone with a detachable anti-collision structure includes a drone body 1. An adjustment chamber 2 is located at the bottom of the drone body 1. A groove 3 is formed on the inner wall of the adjustment chamber 2. An adjustment rod 4 is installed inside the adjustment chamber 2. A positioning block 5 is provided on the side wall of the adjustment rod 4. Bolt insertion holes 6 are formed on the side walls of the adjustment chamber 2 and the adjustment rod 4. A fixing bolt 7 passes through the inner wall of the bolt insertion hole 6. A fixing nut 8 is threaded onto the outer wall of the fixing bolt 7. The adjustment rod 4 and the adjustment chamber 2 form a sliding structure through the positioning block 5, and the positioning block 5 is engaged with the groove 3. The adjustment rod 4 is sleeved with the adjustment chamber 2, and the adjustment rod 4 is threadedly fixed to the adjustment chamber 2 by the fixing bolt 7. When using the device, the fixing nut 8 is removed by turning with a wrench, and the fixing bolt 7 is pulled out of the bolt insertion hole 6. Then, the buffer frame 10 at the bottom of the adjustment rod 4 is held with both hands and pulled vertically downwards at a uniform speed. At this time, the positioning block 5 on the adjustment rod 4 will slide along the inner wall of the adjustment chamber 2. The slide 3 slides smoothly until the adjusting rod 4 is completely removed from the adjusting chamber 2. The damper 11, damping rod 12 and buffer spring 13 inside the buffer frame 10 can be replaced. Then, by aligning the positioning block 5 on the adjusting rod 4 with the slide 3 in the adjusting chamber 2, the adjusting rod 4 is pushed and the bolt hole 6 on the adjusting rod 4 is aligned with the bolt hole 6 on the adjusting chamber 2. When the two are fully aligned, the fixing bolt 7 is passed through the bolt hole 6, and the fixing nut 8 is screwed into the fixing bolt 7 to complete the fixation. By aligning the bolt hole 6 on the adjusting rod 4 with the bolt holes 6 at different heights on the adjusting chamber 2, the height of the UAV body 1 above the ground can be adjusted. This not only realizes the convenient disassembly and assembly of the buffer frame 10 and reduces maintenance costs, but also improves the environmental adaptability of the UAV through the flexible height adjustment function, providing reliable safety for UAV operations in different scenarios.

[0018] Please see Figures 1-4A drone with a detachable anti-collision structure has a buffer block 9 at the bottom of an adjusting rod 4. A buffer frame 10 is installed on the outside of the buffer block 9. A damper 11 is fixedly connected to the inner wall of the buffer frame 10. A damping rod 12 is installed inside the damper 11. A buffer spring 13 is installed on the outer wall of the damper 11. The buffer block 9 and the buffer frame 10 form a telescopic structure through the buffer spring 13. The buffer block 9 is trapezoidal in shape. The buffer spring 13 is sleeved with the damping rod 12, and the surface of the damping rod 12 is in close contact with the outer wall of the buffer block 9. The buffer block 9 and the buffer frame 10 are movably connected. The top of the buffer frame 10 is slotted. When the drone body 1 lands on the ground, the buffer frame 10 contacts the ground, and the drone body 1 is subjected to a reaction force, which drives the buffer block 9 to move downward. Since the buffer block 9 is trapezoidal in shape, its bottom and side slopes are connected to the damping rod. The arc-shaped contact head of 12 fits tightly, converting the downward displacement in the vertical direction into a horizontal component force that pushes the damping rod 12 to contract inward into the damper 11, thus realizing the conversion and dispersion of force direction. At the same time, it compresses the buffer spring 13, and then uses the elasticity of the buffer spring 13 and the damper 11 to buffer and release the reaction force, and drive the damper 11 to reset, and push the buffer block 9 to move slowly upward until the limit baffles on both sides of the buffer block 9 contact the inside of the buffer frame 10, thus completing the buffering. This reduces the damage to the drone body 1 caused by the reaction force generated when the drone body 1 collides with the ground. The trapezoidal buffer block 9 converts the vertical impact into a multi-directional component force, and together with the dampers 11 and buffer spring 13 components at the bottom and sides, it forms a 360° all-round buffer, which can cope with complex impact scenarios such as tilted landing of the drone body 1 and single-sided impact, and solves the limitations of traditional single-direction buffering.

[0019] Working principle: In use, first move the device to a suitable position. Then, when it is necessary to replace or disassemble the buffer frame 10 and its internal dampers 11, damping rods 12, and buffer springs 13, simply use a wrench to turn and remove the fixing nut 8. Then, pull the fixing bolt 7 out of the bolt hole 6. Next, remove the adjusting rod 4 from the adjusting chamber 2 to complete the disassembly of the buffer frame 10 at the bottom of the adjusting rod 4. Then, align the positioning block 5 on the adjusting rod 4 with the sliding groove 3 in the adjusting chamber 2, and push the adjusting rod 4 while aligning the bolt hole 6 on the adjusting rod 4 with the bolt hole 6 on the adjusting chamber 2. Then, pass the fixing bolt 7 through the bolt hole 6, and screw the fixing nut 8 into the fixing bolt 7 to complete the fixing of the buffer frame 10. Simultaneously, by aligning the bolt hole 6 on the adjusting rod 4 with bolt holes 6 at different heights on the adjusting chamber 2, it is possible to operate the buffer frame 10 without human intervention. The height of the drone body 1 above the ground is adjusted. When the drone body 1 lands on the ground, the buffer frame 10 contacts the ground, and the drone body 1 is subjected to a reaction force, which drives the buffer block 9 to move downward. Since the buffer block 9 is trapezoidal in shape, as the buffer block 9 moves downward, it squeezes the damping rods 12 at the bottom and sides and compresses them into the damper 11. At the same time, it compresses the buffer spring 13. Then, the elasticity of the buffer spring 13 and the damper 11 are used to buffer and release the reaction force, and drive the damper 11 to reset. This pushes the buffer block 9 to move upward slowly until the limit baffles on both sides of the buffer block 9 contact the inside of the buffer frame 10, thus completing the buffering. This reduces the reaction force generated when the drone body 1 collides with the ground and causes damage to the drone body 1. This completes the use of the device.
