Description

Technical Field

[0001] This utility model belongs to the field of medium-sized unmanned aerial vehicle (UAV) technology, specifically relating to a medium-sized UAV with stable landing function. Background Technology

[0002] In various applications, medium-sized drones perform exceptionally well. In agricultural plant protection, they can carry large quantities of pesticides, covering vast areas of farmland in a single operation; in logistics and distribution, they can transport heavy goods; when hoisting materials in mountainous areas, they can overcome terrain limitations; and in power line inspection missions, they can continuously fly and inspect long power transmission lines. Simultaneously, medium-sized drones also play a crucial role in surveying and mapping, fire rescue, oil pipeline inspection, and construction monitoring, leveraging their beyond-visual-range flight capabilities to penetrate complex and dangerous areas, providing strong support for the development and operations of various industries.

[0003] Currently, existing medium-sized drones typically rely on their bottom frame for support during takeoff and landing. However, the bottom frame of traditional medium-sized drones often lacks a good anti-slip structure. Therefore, when a medium-sized drone lands on certain surfaces, it may experience a gliding effect, which reduces its stability during landing and thus lowers its overall stability. Utility Model Content

[0004] The purpose of this invention is to provide a medium-sized unmanned aerial vehicle (UAV) with a stable landing function. This invention addresses the problem that existing medium-sized UAVs typically rely on their bottom frame for support during takeoff and landing. However, the bottom frame of traditional medium-sized UAVs often lacks a good anti-slip structure, which can lead to gliding when the UAV lands on certain surfaces. This results in decreased stability during landing and reduces overall stability.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a medium-sized unmanned aerial vehicle (UAV) with stable landing function, comprising a UAV fuselage, wherein four connecting frames are distributed in a ring on the outer wall of the UAV fuselage, a propeller is installed at one end of each of the four connecting frames, and two frames are installed at the bottom of the UAV fuselage, with wear-resistant plates installed at the bottom of the two frames.

[0006] The bottom of the wear-resistant plate is provided with anti-slip texture, and two positioning blocks are fixedly connected to the top of the wear-resistant plate. Limiting slots are opened on the outer walls of the two positioning blocks. Positioning slots are opened at the bottom of the two frames. A mounting base is fixedly connected to the inner side of the frame. A first spring is provided inside the mounting base. A movable block is connected to the end of the first spring. A limiting pin is connected to one end of the movable block.

[0007] As a preferred embodiment of this utility model of a medium-sized unmanned aerial vehicle with a stable landing function, the positioning block can penetrate through the bottom of the frame via a positioning slot.

[0008] As a preferred embodiment of this utility model of a medium-sized unmanned aerial vehicle with a stable landing function, the end of the limiting pin away from the movable block is adapted to the size of the limiting slot.

[0009] As a preferred embodiment of this utility model of a medium-sized unmanned aerial vehicle with stable landing function, the wear-resistant plate can form an elastic engagement structure with the fuselage through a positioning block, a limiting slot, a positioning groove, a mounting base, a first spring, a movable block, and a limiting pin.

[0010] As a preferred embodiment of the present invention, a medium-sized unmanned aerial vehicle with a stable landing function is provided with a connecting seat fixedly connected to the outer wall of the frame, a second spring being provided inside the connecting seat, a connecting block being connected to one end of the second spring, and a plug rod being fixedly connected to one end of the connecting block.

[0011] As a preferred embodiment of this utility model of a medium-sized unmanned aerial vehicle with a stable landing function, one end of the plug extends through to the outside of the connecting seat.

[0012] As a preferred embodiment of this utility model of a medium-sized unmanned aerial vehicle with stable landing function, the insertion rod can form an elastic structure with the connecting seat through the second spring and the connecting block.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By moving the movable block with the toggle, the limit pin retracts, and then the positioning block passes through the bottom of the frame. At this time, the positioning block will be located at both ends of the mounting base. Then, release the toggle, so that the limit pin can pop out under the action of the first spring and insert into the limit slot, thereby installing the wear-resistant plate at the bottom of the frame. The wear-resistant plate and anti-slip texture can improve the friction effect at the bottom of the frame, thereby improving the stability of the medium-sized UAV when landing.

[0015] Through the elastic structure between the insertion rod and the connecting seat, when a medium-sized drone lands on soil, the insertion rod will be inserted into the soil under elastic force, thereby further improving landing stability. When a medium-sized drone lands on cement or asphalt, the weight of the medium-sized drone will press down on the insertion rod, causing it to compress the second spring, thus also improving the friction effect.

[0023] 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.

[0024] Please see Figures 1-5 The present invention provides the following technical solution: a medium-sized unmanned aerial vehicle (UAV) with stable landing function, including a UAV fuselage 1, the outer wall of the UAV fuselage 1 is surrounded by four connecting frames 2, one end of the four connecting frames 2 is equipped with a propeller 3, the bottom of the UAV fuselage 1 is equipped with two frames 4, and the bottom of the two frames 4 is equipped with a wear-resistant plate 5.

[0025] The bottom of the wear-resistant plate 5 is provided with anti-slip texture 6. The top of the wear-resistant plate 5 is fixedly connected with two positioning blocks 7. The outer wall of the two positioning blocks 7 is provided with limit slots 8. The bottom of the two frames 4 is provided with positioning slots 9. The inner side of the frame 4 is fixedly connected with a mounting base 10. The mounting base 10 is provided with a first spring 11. The end of the first spring 11 is connected with a movable block 12. One end of the movable block 12 is connected with a limit pin 13.

[0026] Preferably, the positioning block 7 can penetrate the bottom of the frame 4 through the positioning slot 9, and the end of the limiting pin 13 away from the movable block 12 is adapted to the size of the limiting slot 8. The wear-resistant plate 5 can form an elastic engagement structure with the frame 4 through the positioning block 7, the limiting slot 8, the positioning slot 9, the mounting base 10, the first spring 11, the movable block 12, and the limiting pin 13.

[0027] In practical use, the movable block 12 is moved by the lever to retract the limit pin 13, and then the positioning block 7 passes through the bottom of the frame 4. At this time, the positioning block 7 will be located at both ends of the mounting base 10. Then the lever is released, so that the limit pin 13 can pop out and insert into the limit slot 8 under the action of the first spring 11, thereby installing the wear plate 5 at the bottom of the frame 4. The wear plate 5 and the anti-slip texture 6 can improve the friction effect at the bottom of the frame 4, thereby improving the stability of the medium-sized UAV when landing.

[0028] Conversely, by moving the movable block 12 with the toggle, the limiting pin 13 is retracted. At this time, one end of the limiting pin 13 will disengage from the limiting slot 8. Then, by pulling down the wear-resistant plate 5, the positioning block 7 is disengaged from the positioning slot 9, thus enabling the wear-resistant plate 5 to be easily disassembled.

[0029] Preferably, a connecting seat 14 is fixedly connected to the outer wall of the frame 4, and a second spring 15 is provided inside the connecting seat 14. One end of the second spring 15 is connected to a connecting block 16, and one end of the connecting block 16 is fixedly connected to a plug rod 17. One end of the plug rod 17 extends through to the outside of the connecting seat 14. The plug rod 17 can form an elastic structure with the connecting seat 14 through the second spring 15 and the connecting block 16.

[0030] In practical use, through the elastic structure between the insertion rod 17 and the connecting seat 14, when the medium-sized drone lands on the soil, the insertion rod 17 will be inserted into the soil under elastic action, thereby further improving the landing stability. When the medium-sized drone lands on cement or asphalt, the weight of the medium-sized drone will press down on the insertion rod 17 to compress the second spring 15, thus also improving the friction effect.

[0031] Working principle: First, by moving the movable block 12 with the toggle, the limiting pin 13 is retracted. Then, the positioning block 7 passes through the bottom of the frame 4. At this time, the positioning block 7 will be located at both ends of the mounting base 10. Then, the toggle is released, so that the limiting pin 13 can pop out under the action of the first spring 11 and insert into the limiting slot 8, thereby installing the wear-resistant plate 5 at the bottom of the frame 4. The wear-resistant plate 5 and the anti-slip texture 6 can improve the friction effect at the bottom of the frame 4, thereby improving the stability of the medium-sized UAV when landing. In addition, through the elastic structure between the insertion rod 17 and the connecting base 14, when the medium-sized UAV lands on the soil, the insertion rod 17 will be inserted into the soil under the elastic action, thereby further improving the landing stability. When the medium-sized UAV lands on the cement or asphalt ground, the weight of the medium-sized UAV will press down the insertion rod 17 to squeeze the second spring 15, thus also improving the friction effect.

[0032] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
