Abstract
Description
Technical Field
[0001] This utility model relates to the field of drone technology, specifically a lightweight anti-collision drone protective cover structure. Background Technology
[0002] Traditional drone protective canopy structures typically employ a single reinforcing structure (such as an all-metal frame or thickened plastic) to withstand strong impacts, resulting in a significant increase in overall weight and impacting flight endurance and maneuverability.
[0003] Disadvantages of existing technology: Metal frame protective cover: heavy weight and high energy consumption.
[0004] • Pure plastic protective cover: lacks toughness and has poor resistance to repeated impacts.
[0005] Honeycomb structure protective cover: weak lateral support, unable to disperse impact force.
[0006] In response, this technical solution proposes a lightweight anti-collision drone protective cover structure. Utility Model Content
[0007] The purpose of this invention is to provide a lightweight anti-collision drone protective cover structure to solve the problems mentioned in the background art.
[0008] To achieve the above objectives, this utility model provides the following technical solution:
[0009] A lightweight anti-collision drone protective cover structure includes a drone body, a motor mount, landing gear, arms, and rotors. The motor mount is located in the middle of the drone body, housing a motor. Landing gears are symmetrically mounted on both sides of the bottom of the drone body. The arms are arranged in four sets in an "X" shape. Each arm has two sets of rotors at its upper and lower ends. A fan-shaped ABS protective frame covers the outer periphery of the two sets of rotors at the same arm end. A hollowed-out frustum support frame is mounted on the top center of the drone body. A connecting ring is fixedly installed on the top of the frustum support frame. A carbon fiber support tube is embedded inside the ABS protective frame located above and below the rotors. The upper end of the carbon fiber support tube, away from the ABS protective frame, is embedded in the connecting ring, while the lower end is embedded in a fixed sleeve mounted on the landing gear. Through the connection of two carbon fiber support tubes and the middle of the inner side of the ABS protective frame to the arm ends, the four sets of ABS protective frames are stably distributed around the rotors, providing anti-collision protection.
[0010] Carbon fiber support tubes are embedded on both the upper and lower sides between adjacent ABS protective frames. The carbon fiber support tubes on both sides are connected by cross-distributed tension lines with an intersection angle of 45°-60°. The tension lines ensure that the ABS protective frame absorbs energy through deformation during a collision. At the same time, the design of the carbon fiber support tubes between the ABS protective frames and between the ABS protective frame and the connecting ring and landing gear can enhance longitudinal compressive strength.
[0011] Compared with the prior art, the beneficial effects of this utility model are: by using an ABS protective frame (mesh hollow) combined with a carbon fiber support tube, the impact force is dispersed through longitudinal rigid support and transverse flexible connection;
[0012] By embedding carbon fiber tubes into connecting rings and landing gear fixing sleeves, and by crisscrossing and connecting adjacent protective frames with tightening lines, quick assembly and disassembly can be achieved.
[0013] Wheels can be added to the outside of the pipe connecting block to improve ground mobility. Attached Figure Description

[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0023] Please see Figures 1-3A lightweight anti-collision drone protective cover structure includes a drone body 10, a motor mount 11, landing gear 12, arms 13, and rotors 14. The motor mount 11 is located in the middle of the drone body 10, and a motor is installed inside the motor mount 11. Landing gears 12 are symmetrically installed on both sides of the bottom of the drone body 10. The arms 13 have four sets arranged in an "X" shape. Each set of arms 13 has two sets of rotors 14 located on the upper and lower sides of its end. A fan-shaped ABS protective frame 15 covers the outer periphery of the two sets of rotors 14 at the end of the same arm 13. A hollowed-out frustum support is installed at the top center of the drone body 10. The top of the support frame 16 and the truncated cone support frame 16 is fixedly installed with a connecting ring 17. A carbon fiber support tube 20 is embedded in the inner side of the ABS protective frame 15 located above and below the rotor 14. The end of the upper carbon fiber support tube 20 away from the ABS protective frame 15 is embedded in the connecting ring 17, and the end of the lower carbon fiber support tube 20 away from the ABS protective frame 15 is embedded in the fixed sleeve installed on the landing gear 12. Through the connection of the two carbon fiber support tubes 20 and the middle of the inner side of the ABS protective frame 15 to the end of the arm 13, the four sets of ABS protective frames 15 are stably distributed on the outer periphery of the rotor 14 to protect it from collision.
[0024] Carbon fiber support tubes 20 are embedded on the upper and lower sides between adjacent ABS protective frames 15. The carbon fiber support tubes 20 on both sides are connected by cross-distributed tension lines 18 with a cross angle of 45°-60°. The cross points are connected by buckles. The tension lines 18 ensure that the ABS protective frame 15 absorbs energy through deformation during a collision. At the same time, the design of the carbon fiber support tubes 20 between the ABS protective frames 15 and the carbon fiber support tubes 20 between the ABS protective frame 15 and the connecting ring 17 and the landing gear 12 can enhance longitudinal compressive strength.
[0025] The ABS protective frame 15 is made of 3D printed ABS plastic with a mesh-like hollow structure on the surface. The mesh density is 8-12 holes / cm², and the wall thickness is 1.5-2mm. A set of motor mounts 11 is fixedly installed in the middle of the top of the drone body 10.
[0026] In this embodiment of the invention, the connecting ring 17 has radially distributed embedding holes on its circumferential sidewall, and the fixed sleeve on the landing gear 12 also has embedding holes facing the ABS protective frame 15. Each embedding hole is also provided with an embedding tube on the ABS protective frame 15. The embedding holes and embedding tubes cooperate with the carbon fiber support tube 20 to quickly install and remove the carbon fiber support tube 20.
[0027] The fixing sleeve adopts a semi-open structure, is fitted onto the landing gear 12, and is then fixed with bolts. For details, please refer to the attached diagram in the instruction manual.
[0028] Both ends of the carbon fiber support tube 20 located between adjacent ABS protective frames 15 are provided with tube connecting blocks 21 fixedly installed on the side wall of the ABS protective frame 15. The tube connecting blocks 21 are detachably installed on the ABS protective frame 15. The tube connecting blocks 21 are provided with embedding holes at the positions corresponding to the ends of the carbon fiber support tube 20 for the installation and removal of the carbon fiber support tube 20. At the same time, the tube connecting blocks 21 corresponding to the ends of the tightening line 18 are provided with connecting holes. The ends of the tightening line 18 are bolted in the connecting holes to maintain the connection and disconnection of the tightening line 18.
[0029] In one embodiment of the present invention, the connection, distribution, and operational relationship between the UAV body 10, motor mount 11, the motor inside the motor mount 11, the arm 13, and the rotor 14 can be achieved using existing technologies. Meanwhile, the core of this technical solution is the protective cover structure set on the outer periphery of the UAV body 10. It has no direct connection with the specific connection and operation between the UAV body 10, the motor, the arm 13, and the rotor 14, and conventional technologies can be used. Therefore, even if it is not described, it will not affect the integrity and disclosure of the technical solution.
[0030] In a preferred embodiment of the present invention, the inner side of the ABS protective frame 15 is fixedly connected to the end of the arm 13 at the position corresponding to the end of the arm 13, and a carbon fiber support tube 20 is provided on the inner side of the ABS protective frame 15 located at the upper and lower rotors 14 facing the top of the UAV body 10.
[0031] As a preferred embodiment of the present invention, see [reference]. Figure 4 On the same side of the four sets of pipe connecting blocks 21, an L-shaped wheel axle 22 with an L-shaped structure is installed outward. The end of the L-shaped wheel axle 22 is fitted with a movable wheel 23 through a bearing. The moving direction of the movable wheel 23 is perpendicular to the lifting direction of the UAV body 10. The rolling of the four sets of movable wheels 23 improves the maneuverability of the entire UAV when it is carried.
[0032] A locking hole is provided at the end of the L-shaped wheel axle 22 corresponding to the position on the tube connecting block 21. The end of the L-shaped wheel axle 22 is locked into the locking hole, which facilitates the installation and removal of the movable wheel 23.
[0033] In another preferred embodiment of the present invention, the carbon fiber support tube 20 can be replaced with a glass fiber tube, and the tightening line 18 can be made of nylon fishing line or elastic rubber strip; the ABS mesh can be changed to a triangular hollow structure or hexagonal unit. The technical effects of the replaced materials or structures are similar to those described above, so they will not be described in detail here.
[0034] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
