Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a UAV structure with a waterproof casing. Background Technology

[0002] With the continuous development of technology, drones have been widely used in various fields such as aerial surveying and mapping, agricultural plant protection, power line inspection, and emergency rescue due to their flexible operation and wide applicability. However, in actual use, drones face many challenges, which drive the continuous improvement of related technologies.

[0003] When operating in complex environments, drone propellers are highly susceptible to collisions with surrounding obstacles, leading to propeller damage. This not only affects flight safety but also increases equipment maintenance costs. Traditional drone propellers lack effective protective structures, or their protective devices are cumbersome to install and have poor stability, making them difficult to meet practical usage requirements. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a drone structure with a waterproof casing. Through the implementation of protective measures, damage to the drone propellers can be prevented, thereby extending its service life.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A drone structure with a waterproof casing includes a drone body, connecting arms fixedly connected to the four sides of the drone body, a mounting base fixedly connected to the end of each connecting arm, a servo motor fixedly connected inside the mounting base, a propeller fixedly connected to the drive end of the servo motor, a protective cover fixedly connected to the lower side of the propeller, a retaining ring provided on the outside of the propeller, a slide rail fixedly connected to the bottom of the retaining ring, a slider slidably connected to the outside of the slide rail, a fixing block fixedly connected to the lower side of the slider, the inner wall of the fixing block tightly fitting the outer wall of the connecting arm, a bolt threadedly connected to the upper end of the fixing block for fixing, and a buffer assembly installed on the lower side of the drone body.

[0007] Furthermore, a connecting rod is fixedly connected to the other end of the lower side of the slide rail, and an elastic clip is fixedly connected to the end of the connecting rod. An anti-slip pad is fixedly connected to the inner side of the elastic clip, and the inner wall of the elastic clip is in close contact with the outer wall of the mounting base.

[0008] Furthermore, the upper end of the retaining ring is externally threaded with a threaded ring, and a guide ring is fixedly connected to the upper side of the threaded ring.

[0009] Furthermore, a cross is fixedly connected to the inner side of the threaded ring, and a flow guide is fixedly connected to the lower side of the cross, with the flow guide positioned in the middle of the upper side of the propeller.

[0010] Furthermore, the buffer assembly includes a T-shaped plate fixedly connected to the bottom of the drone body, a base plate slidably connected to the outer side of the T-shaped plate, and fasteners for fixing threaded to both ends of the base plate.

[0011] Furthermore, the buffer assembly also includes a rotating component fixedly connected to the front and rear ends of the base plate, a support frame rotatably connected to the middle of the rotating component, and a rotating roller rotatably connected to the lower outer end of the support frame.

[0012] Furthermore, the buffer assembly further includes an adjustment frame disposed below the base plate. A limit rod is fixedly connected to the inner center of the adjustment frame. Movable plates are slidably connected to both sides of the center of the limit rod. Movable rods are fixedly connected to the left and right ends of the opposite side of the movable plates. Springs are disposed on the outside of the movable rods.

[0013] Furthermore, the ends of the movable rod pass through the front and rear ends of the adjustment frame and are fixedly connected to a rotating cylinder. A reinforcing rod is rotatably connected inside the rotating cylinder, and the two ends of the reinforcing rod are fixedly connected to the outside of the support frame.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the retaining ring provides solid protection for the propeller from the side, which can effectively prevent the drone from directly colliding with obstacles such as tree branches and walls during flight, greatly reducing the probability of propeller damage and significantly extending the service life of the propeller. The retaining ring is easy and quick to install by fixing blocks.

[0016] 2. In this utility model, when the impact force of the drone's descent causes the support frame to rotate to both sides, it is transmitted to the movable rod through the reinforcing rod and the rotating cylinder, causing the movable plate to slide on the limiting rod, thereby compressing the spring. The elastic deformation of the spring converts the impact force into elastic potential energy, effectively buffering and absorbing the impact force during landing, reducing the vibration impact on the drone's main body and internal precision components, and protecting the fuselage structure and equipment components.

[0026] 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.

[0027] Reference Figures 1-3This utility model provides an embodiment of a drone structure with a waterproof casing, comprising a drone body 1, connecting arms 2 fixedly connected to the four sides of the drone body 1, a mounting base 3 fixedly connected to the end of the connecting arms 2, a servo motor 4 fixedly connected inside the mounting base 3, a propeller 5 fixedly connected to the drive end of the servo motor 4, a protective cover 6 fixedly connected to the lower side of the propeller 5, a retaining ring 7 provided outside the propeller 5, a slide rail 8 fixedly connected to the bottom of the retaining ring 7, a slider 9 slidably connected to the outside of the slide rail 8, a fixing block 10 fixedly connected to the lower side of the slider 9, and the inner wall of the fixing block 10 being connected to the connecting arms 2. The outer wall of the mounting bracket 3 is tightly fitted. The upper end of the fixing block 10 is threaded with a bolt 11 for fixing. The other end of the lower side of the slide rail 8 is fixedly connected with a connecting rod 12. The end of the connecting rod 12 is fixedly connected with an elastic clip 13. The inner side of the elastic clip 13 is fixedly connected with an anti-slip pad 14. The inner wall of the elastic clip 13 is tightly fitted with the outer wall of the mounting base 3. The upper end of the retaining ring 7 is threaded with a threaded ring 15. The upper side of the threaded ring 15 is fixedly connected with a guide ring 18. The inner side of the threaded ring 15 is fixedly connected with a cross 16. The lower side of the cross 16 is fixedly connected with a guide shield 17. The guide shield 17 is located in the middle of the upper side of the propeller 5.

[0028] During installation, first push the fixing block 10 to slide on the slide rail 8, separating the two fixing blocks 10 from each other to make room for the placement of the retaining ring 7. After placing the retaining ring 7 on the outside of the propeller 5, fasten the elastic clip 13 to the outside of the mounting base 3, using the elastic force of the elastic clip 13 to initially clamp the mounting base 3. Next, move the two fixing blocks 10 to both sides of the connecting arm 2 and slide them towards the middle. The clamping of the connecting arm 2 by the fixing blocks 10 forms a second layer of fixation. The connecting arm 2 is shaped like a thicker end and a thinner middle. After the two fixing blocks 10 are close together, they are located in the middle of the connecting arm 2, preventing it from moving to either end. Turn the bolt 11 so that its end is screwed into the threaded hole of the other fixing block 10 to achieve fixation. By using the retaining ring 7, the propeller 5 can be protected during drone flight. During flight, the baffle ring 7 provides protection for the propeller 5 from the side, preventing direct collisions with obstacles such as branches and walls, reducing the probability of damage to the propeller 5, and extending its service life. The ring structure of the baffle ring 7 can also reduce airflow disturbances generated when the propeller 5 rotates, making the drone fly more smoothly and improving control precision. It is easy and quick to install and fix by the fixing block 10. After the baffle ring 7 is installed, the threaded ring 15 can be fixed to the top of the baffle ring 7 by rotation. The cross 16 and the air deflector 17 on the lower side of the threaded ring 15 can further protect the propeller 5 from the top, preventing rainwater from entering the gaps. The shell of the drone body 1 is made of waterproof material, and waterproof sealing gaskets are set at its joints to ensure its overall waterproof performance.

[0029] Reference Figures 5-7The bottom of the drone body 1 is fixedly connected to a T-shaped plate 19. A base plate 20 is slidably connected to the outside of the T-shaped plate 19. Fasteners 21 for fixing are threaded to both ends of the base plate 20. Rotating parts 22 are fixedly connected to the front and rear ends of the base plate 20. A support frame 23 is rotatably connected to the middle of the rotating parts 22. A rotating roller 24 is rotatably connected to the lower end of the support frame 23. An adjustment frame 27 is set below the base plate 20. A limit rod 28 is fixedly connected to the middle of the inner side of the adjustment frame 27. Movable plates 29 are slidably connected to both sides of the middle of the limit rod 28. Movable rods 30 are fixedly connected to the left and right ends of the opposite side of the movable plate 29. A spring 31 is set on the outside of the movable rod 30. The ends of the movable rods 30 pass through the front and rear ends of the adjustment frame 27 and are fixedly connected to a rotating cylinder 26. A reinforcing rod 25 is rotatably connected inside the rotating cylinder 26. The two ends of the reinforcing rod 25 are fixedly connected to the outside of the support frame 23.

[0030] When the drone lands and contacts the ground, the rotating roller 24 contacts the ground first. Its rolling characteristics can reduce the frictional resistance during landing and prevent the support frame 23 from being damaged by a hard collision with the ground. The impact force will cause the support frame 23 to rotate to both sides, and the force will be transmitted to the movable rod 30 through the reinforcing rod 25 and the rotating cylinder 26. The movable rod 30 drives the movable plate 29 to slide on the limiting rod 28, thereby compressing the spring 31. The elastic deformation of the spring 31 converts the impact force into elastic potential energy, effectively buffering and absorbing the impact force during landing, reducing the vibration impact on the main body 1 of the drone and its internal precision components, and protecting the fuselage structure and equipment components.

[0031] Working principle: Before the drone takes off, when installing the retaining ring 7, the fixing block 10 slides outside the slide rail 8, so that the two fixing blocks 10 are far apart. Then, the retaining ring 7 is placed outside the propeller 5, and the elastic clip 13 is placed outside the mounting base 3. The mounting base 3 is clamped by the elastic force of the elastic clip 13. Then, the two fixing blocks 10 are placed on both sides of the connecting arm 2 and slid towards the middle. The connecting arm 2 is clamped by the fixing blocks 10. Then, the bolt 11 is rotated so that its end is threaded into the threaded hole on the other fixing block 10 to fix it. Then, by rotating, the threaded ring 15 is installed on the top of the retaining ring 7 to protect the propeller 5 from above. When the drone lands, the set support frame 23 contacts the ground through the rotating roller 24. When the impact force generated during the fall contacts the ground, it causes the support frame 23 to rotate to both sides, thereby pulling the movable rod 30 through the reinforcing rod 25 and the rotating cylinder 26. The movable rod 30 drives the movable plate 29 to move, thereby compressing the spring 31 and playing a buffering role.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
