Description

Technical Field

[0001] This utility model relates to the field of drone blade technology, and in particular to a drone device with easily replaceable blades. Background Technology

[0002] The main advantages of drone blades that are easy to replace are as follows: Drone blades may be damaged during flight due to collisions, wear, or human error. If the blades can be quickly replaced, there is no need to send the entire drone back to the factory for repair. Operators can replace them directly on-site, significantly reducing drone downtime. This is especially suitable for scenarios with high timeliness requirements, such as emergency rescue and inspection. Replacing blades on traditional drones may require specialized tools or complex disassembly and assembly procedures, while modular quick-release blades only require a few steps, lowering the maintenance threshold and allowing non-professionals to complete the task, thus reducing reliance on technical teams.

[0003] However, existing technologies, such as Chinese Publication No. CN216035108U, "A Blade Protection Device for Unmanned Aerial Vehicles," belong to the field of protective equipment technology, specifically a blade protection device for unmanned aerial vehicles (UAVs). Addressing the problem that most existing UAVs lack blade protection measures, leading to easy collisions and damage during flight, the following solution is proposed: It includes a UAV body and four protective rails. Vertical columns are fixedly installed at the bottom of the protective rails. Four vertical holes are opened at the top of the UAV body. The outer sides of the four vertical columns movably abut against the inner walls of the corresponding vertical holes. The bottom ends of the four vertical columns extend to the outer side of the UAV body. Four housings are fixedly installed at the bottom of the UAV body, with transverse through holes on the outer side of the housings. This utility model has a reasonable structural design. Through the interlocking action of the clamping plates and vertical columns, the protective rails can be quickly installed and disassembled, facilitating replacement with new rails and ensuring high reliability.

[0004] However, this device does not have a quick-release blade structure. The drone blades may be damaged during flight due to collisions, wear, or harsh environments. This prevents users from removing old blades and installing new ones in a short time. This leads to delays in use due to waiting for professional repairs or complicated disassembly and assembly processes. The inability to replace worn blades in time may cause increased vibration of the motor and fuselage due to blade imbalance, thereby increasing the wear and tear on the core components of the drone and shortening the overall service life of the aircraft. Utility Model Content

[0005] The purpose of this invention is to address the problem in the existing technology that drone blades may be damaged during flight due to collisions, wear, or harsh environments, preventing users from quickly removing old blades and installing new ones. This leads to delays in use due to waiting for professional repairs or complex disassembly and assembly processes. Furthermore, the inability to replace worn blades in a timely manner may cause increased vibration of the motor and fuselage due to blade imbalance, thereby increasing the wear and tear on the core components of the drone and shortening the overall lifespan of the aircraft.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a drone device with easily replaceable blades, comprising multiple main housings. The top of each main housing has an internal threaded groove, and a threaded rod is threadedly connected to the inner surface of the internal threaded groove. A main board is rotatably connected to the bottom of the threaded rod. A fastening assembly is provided on the outer surface of the main board. The fastening assembly includes two limiting blocks, one side of which is fixedly connected to the outer surface of the main board. Limiting grooves are formed on both sides of the inner surface of the main housing. The outer surfaces of the limiting blocks are movably embedded within the limiting grooves. Two short rods are fixedly connected to the bottom of the main board. The outer surfaces of the two short rods are movably embedded within the main housing. A blade body is movably sleeved on the outer surface of each short rod. The main board and limiting blocks rise vertically along the groove direction of the limiting grooves, and simultaneously the short rods detach from the main housing, at which point the blade body can be removed from the outer surface of the short rods.

[0007] In a preferred embodiment, the bottom of the motherboard is fixedly connected to two long rods, the outer surfaces of the two long rods are movably embedded inside the main body casing, and the bottom of the long rods is fixedly connected to a slanted push block, the slanted push block is provided with a through groove, and the main rod can move along the inside of the through groove.

[0008] In a preferred embodiment, a main rod is provided inside the through groove, and the outer surfaces of the two main rods are movably embedded on both sides of the main housing. An inclined receiving block is fixedly sleeved on the outer surface of the main rod, and one side of the inclined receiving block is provided on the outer surface of the inclined push block. The inclined push block, which rises with the long rod, will rub against the inclined receiving block.

[0009] In a preferred embodiment, slots are provided on both sides of the main housing, and a force-bearing plate is fixedly connected to one end of the main rod, allowing the main rod to move inside the slots.

[0010] In a preferred embodiment, a spring is movably sleeved on the outer surface of the main rod. One end of the spring away from the force plate is fixedly connected to the inside of the slot, and the other end of the spring is fixedly connected to one side of the force plate. Under the elastic action of the spring on the force plate and the slot, the main rod and the clamping block will extend outward along the axial direction of the limiting rod.

[0011] In a preferred embodiment, a clamping block is fixedly connected to the end of the main rod away from the force plate. The clamping block has a clamping groove. The main rod moves along the inside of the groove so that the clamping groove no longer clamps the output end of the motor, and then the main housing can be removed from the top of the motor.

[0012] In a preferred embodiment, the clamping block is fixedly connected to a limiting rod on the side near the main rod, and the outer surfaces of the two limiting rods are movably embedded inside the main housing. The main rod and the clamping block extend outward along the axial direction of the limiting rods.

[0013] In a preferred embodiment, a motor is installed inside the two clamping slots, and a connecting pipe is fixedly connected to the outer surface of the motor. The ends of the multiple connecting pipes away from the motors are fixedly connected to the main body of the drone, and the motors are connected to the outside of the main body of the drone through the connecting pipes.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] This invention features a quick-release blade structure. UAV blades may be damaged during flight due to collisions, wear, or harsh environments. This allows users to quickly remove old blades and install new ones, avoiding delays caused by waiting for professional repairs or complicated disassembly and assembly processes. Timely replacement of worn blades can prevent increased vibration of the motor and fuselage due to blade imbalance, thereby reducing wear on the core components of the UAV and extending the overall service life of the aircraft.

[0024] Please see Figures 1 to 5 This utility model provides a technical solution: a drone device with easily replaceable blades, comprising multiple main housings 1. The top of the main housing 1 is provided with an internal threaded groove 2. The inner surface of the internal threaded groove 2 is threadedly connected to a threaded rod 3. The bottom of the threaded rod 3 is rotatably connected to a main board 4. The outer surface of the main board 4 is provided with a fastening assembly, which includes two limiting blocks 5.

The outer surface of the limiting blocks 5 is movably embedded in the inside of the limiting grooves 6. The bottom of the main board 4 is fixedly connected to two short rods 7. The outer surface of the two short rods 7 is movably embedded in the inside of the main housing 1. The outer surface of the short rods 7 is movably sleeved with a blade body 8. Rotating the thread will pull the threaded rod 3, the main board 4, and the limiting blocks 5 to rise vertically along the slotting direction of the limiting grooves 6.

[0025] like Figures 1 to 5 As shown, the bottom of the motherboard 4 is fixedly connected to two long rods 9. The outer surfaces of the two long rods 9 are movably embedded inside the main body shell 1. The bottom of the long rods 9 is fixedly connected to a slanted push block 10. A through groove 11 is opened on the slanted push block 10, and the main rod 12 can move along the inside of the through groove 11.

[0026] like Figures 1 to 5 As shown, a main rod 12 is provided inside the through groove 11. The outer surfaces of the two main rods 12 are movably embedded on both sides of the main housing 1. An inclined receiving block 13 is fixedly sleeved on the outer surface of the main rod 12. One side of the inclined receiving block 13 is provided on the outer surface of the inclined push block 10. The inclined push block 10, which rises with the long rod 9, will rub against the inclined receiving block 13.

[0027] like Figures 1 to 5As shown, slots 14 are provided on both sides of the main housing 1, and a force plate 15 is fixedly connected to one end of the main rod 12, allowing the main rod 12 to move inside the slots 14.

[0028] like Figures 1 to 5 As shown, a spring 16 is movably sleeved on the outer surface of the main rod 12. One end of the spring 16 away from the force plate 15 is fixedly connected to the inside of the slot 14, and the other end of the spring 16 is fixedly connected to one side of the force plate 15. The spring 16 has an elastic effect on the force plate 15 and the slot 14.

[0029] like Figures 1 to 5 As shown, a clamping block 17 is fixedly connected to the end of the main rod 12 away from the force plate 15. A clamping groove 18 is provided on the clamping block 17. The main rod 12 moves along the inside of the through groove 11 so that the clamping groove 18 no longer clamps the output end of the motor 20. Then the main housing 1 can be removed from the top of the motor 20.

[0030] like Figures 1 to 5 As shown, the clamping block 17 is fixedly connected to the limiting rod 19 on the side near the main rod 12. The outer surfaces of the two limiting rods 19 are movably embedded inside the main housing 1.

The ends of the multiple connecting pipes 21 away from the motors 20 are fixedly connected to the main body 22 of the drone. The main rod 12 moves along the inside of the through slot 11 so that the clamping slots 18 no longer clamp the output end of the motors 20. Then the main body shell 1 can be removed from the top of the motors 20.

[0032] Working principle: When it is necessary to disassemble the blade body 8 inside the main housing 1, the threaded rod 3 can be rotated inside the internal threaded groove 2. The rotation of the threaded rod will pull the threaded rod 3, the main board 4, and the limiting block 5 vertically upward along the slotting direction of the limiting groove 6. At the same time, the short rod 7 will fall out of the main housing 1, and the blade body 8 can then be removed from the outer surface of the short rod 7. When it is necessary to replace the main housing 1 assembly, as the main board 4 and the limiting block 5 rise vertically along the slotting direction of the limiting groove 6, the long rod 9 also... It will rise vertically, and the inclined push block 10, which rises with the long rod 9, will rub against the inclined receiving block 13. At the same time, under the elastic action of the spring 16 on the force plate 15 and the slot 14, the main rod 12 and the clamping block 17 will extend outward along the axis of the limiting rod 19. The main rod 12 moves along the inside of the through slot 11, so that the clamping slot 18 no longer clamps the output end of the motor 20. Then the main body shell 1 can be removed from the top of the motor 20. The motor 20 is connected to the outside of the drone body 22 through the connecting pipe 21.
