Description

Technical Field

[0001] The utility model relates to the technical field of anti-collision unmanned aerial vehicles (UAVs), in particular to a UAV with an anti-collision mechanism. Background Art

[0002] A drone is an unmanned aircraft controlled by a radio remote control device and its own program control device, or operated completely or intermittently autonomously by an onboard computer. Compared with manned aircraft, drones are often more suitable for dangerous tasks. The current application of drones in aerial photography, agriculture, plant protection, micro selfies, express delivery, disaster relief, wildlife observation, infectious disease monitoring, surveying and mapping, news reporting, power inspection, disaster relief, film and television shooting, and romance creation has greatly expanded the use of drones themselves. Developed countries are also actively expanding industry applications and developing drone technology.

[0003] Existing aerial photography drones are not perfect in terms of anti-collision or fall protection. When a drone is taking aerial photography, it may collide with an obstacle due to the operator's failure to react in time. When colliding with an obstacle, the first thing that happens is the protective ring outside the drone's blade touches the obstacle. If the buffering performance of the protective ring is poor, the blade will be damaged, which will lead to the crash of the drone, resulting in damage to the shooting equipment carried by the drone, resulting in economic losses. Therefore, a drone with an anti-collision mechanism is designed to solve this problem. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the existing technology and propose a drone with an anti-collision mechanism, which makes it easy to improve the anti-collision performance of the drone, avoid damage to the drone after collision or falling, and enable it to float when it falls into water, reducing losses, so that the drone with an anti-collision mechanism has better use effect and high practicality.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A drone with an anti-collision mechanism is designed, comprising a fuselage, wherein side wings are connected on all four sides of the fuselage, a main rod is vertically installed on the inner middle part of the fuselage through a mounting frame, two corresponding sides of the main rods are connected to auxiliary rods, the outer sides of the two main rods are respectively provided with supporting sleeves, the outer sides of the two auxiliary rods are respectively provided with ring sleeves, the two auxiliary rods pass through the auxiliary rods and extend to the corresponding sides thereof and are jointly provided with a second spring, the two auxiliary rods are located inside the ring sleeves and are connected with a limiting plate, the upper and lower ends of the fuselage are both laterally symmetrically provided with fixing rods through mounting plates, the left and right sides of the fixing rods are both provided with sleeves, the inner sides of the side wings are fixedly provided with motors through second mounting frames, and the upper ends of the motors are fixed through output shafts The cam is provided with a plurality of paddle wheels, and the outer sides of the paddle wheels are connected to the side shells. The upper and lower ends of the interior of the side shells are provided with sleeves. The interiors of each two paddle wheels are vertically inserted with reinforcement rods. Each two paddle wheels pass through the sleeves and the paddle wheels and extend to the side away from each other and are movably connected to the second connecting rod through the second connecting piece. The second connecting rods are connected to the sleeve block through the third connecting piece. Each two paddle wheels are located on the side away from each other inside the sleeve and are welded with a baffle. Each two paddle wheels are located inside the sleeve and on the side corresponding to the two baffles and are provided with a first spring. The left and right sides of the two ends away from each other are movably connected to the first connecting rod through the fourth connecting piece. The first connecting rod is connected to the sleeve block through the fifth connecting piece.

[0007] Preferably, protective nets are provided at both the upper and lower ends of the side wings, and the grid cross density of the protective nets is 0.5-1 cm.

[0008] Preferably, the side shell is made of drop-resistant rubber.

[0009] Preferably, a buoyancy ball is connected to the outer side of the side shell, and the buoyancy ball is made of elastic buoyancy sponge.

[0010] Preferably, the reinforcement rod is made of hard stainless steel.

[0011] Preferably, a cavity is provided inside the side shell, and the above-mentioned components penetrate through and extend into the cavity.

[0012] The beneficial effects of the utility model are:

[0013] The user turns on the motor switch from an external controller, causing the motor to rotate through the output shaft and drive the blades to rotate. The rotation of the blades creates buoyancy for the drone, allowing it to rise and perform aerial photography. When the drone encounters an emergency and falls, multiple reinforcement rods touch the ground simultaneously, causing the reinforcement rods to exert pressure on the baffle inside the sleeve, causing the baffle to compress the first spring, causing the first spring to contract, thereby buffering the impact force and protecting the main body and minimizing damage. The inward movement of the reinforcement rods simultaneously drives the second connecting rod to generate pressure, thereby driving the sleeve block to move on the fixed rod and the first connecting rod to move inward. The support sleeve block slides on the main rod and then slides onto the secondary rod, driving the ring sleeve to move, compressing the second spring, thereby secondary offsetting the impact force. After multiple buffering operations, vibration and direct collision to the drone body are eliminated, extending its service life and facilitating its use. Buoyant balls set around the drone can help the drone float on the water surface if it accidentally falls into water, preventing it from sinking, increasing its practicality and minimizing damage.

[0014] Compared with the existing technology, the utility model has a reasonable structure, which makes it easy to improve the anti-collision performance of the drone, avoid damage to it after collision or falling, and when it falls into the water, it can float, reducing losses, making the drone with an anti-collision mechanism more effective and highly practical.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-5 , a UAV with an anti-collision mechanism includes a fuselage 1, with side wings 18 connected to all sides of the fuselage 1, a main rod 17 is vertically installed on the inner middle part of the fuselage 1 through a mounting frame, and the corresponding sides of the two main rods 17 are connected to the auxiliary rods 12, the outer sides of the two main rods 17 are respectively provided with support sleeves 16, and the outer sides of the two auxiliary rods 12 are respectively provided with ring sleeves 5, and the two auxiliary rods 12 pass through the auxiliary rods 12 and extend to the corresponding sides thereof and are jointly provided with a second spring 20, and the two auxiliary rods 12 are connected to the limiting plates 21 inside the ring sleeves 5, and the upper and lower ends of the fuselage 1 are laterally symmetrically provided with fixing rods 4 through mounting plates, and the left and right sides of the fixing rods 4 are provided with sleeves 2, the inner sides of the side wings 18 are fixedly installed with motors 15 through second mounting frames, and the upper ends of the motors 15 are fixedly provided with blades 7 through output shafts, and the outer sides of the side wings 18 are respectively connected with side shells 19, which are made of anti-fall rubber, so as to prevent the UAV shell from being damaged, reduce the maintenance rate and reduce the loss.

[0023] The outer side of the side shell 19 is connected to a buoyancy ball 10, which is made of elastic buoyancy sponge, so as to generate buoyancy for the drone in the water body and prevent it from sinking and causing economic losses.

[0024] Sleeves 9 are provided at the upper and lower ends of the side shell 19, and reinforcement rods 8 are vertically inserted into the interior of each two sleeves 9. The reinforcement rods 8 are made of hard stainless steel, which is convenient for improving the anti-collision type of the drone structure, avoiding easy deformation under the impact of force, and better protecting the drone body.

[0025] A cavity is provided inside the side shell 19, and 8 penetrates 18 and 9 and extends into the cavity, so as to facilitate the control of the buffer distance and reduce vibration.

[0026] Every two reinforcement rods 8 pass through the sleeve 9 and the side wing 18 and extend to the side away from it and are movably connected to the second connecting rod 6 through the second connecting piece. The second connecting rod 6 is connected to the sleeve block 2 through the third connecting piece. Every two reinforcement rods 8 are located inside the sleeve 9 on the side away from each other and are welded with a baffle 13. Every two reinforcement rods 8 are located inside the sleeve 9 and on the side corresponding to the two baffles 13 and are fitted with a first spring 11. The left and right sides of the two ends 16 away from each other are movably connected to the first connecting rod 3 through the fourth connecting piece. The first connecting rod 3 is connected to the sleeve block 2 through the fifth connecting piece.

[0027] The upper and lower ends of the side wings 18 are both provided with protective nets 14 , and the mesh cross density of the protective nets 14 is 0.5-1 cm, which is convenient for preventing external objects from entering the internal structure and damaging it, thereby improving the safety of use.

[0028] Working principle: When the utility model is in use, the user turns on the switch of the motor 15 from the external controller, so that the motor 15 works and rotates through the output shaft to drive the blades 7 to rotate. The rotation of the blades 7 makes the drone generate buoyancy, thereby rising to perform aerial photography. When the drone encounters an emergency and falls, first, multiple reinforcement rods 8 touch the ground at the same time, so that the reinforcement rods 8 generate an extrusion force on the baffle 13 inside the sleeve 9, so that the baffle 13 squeezes the first spring 11, causing the first spring 11 to contract, facilitating a buffering of the impact force, protecting the main body and reducing losses, and driving the second connecting rod to generate while the reinforcement rod 8 moves inward. The extrusion force drives the sleeve block 2 to move on the fixed rod 4, while driving the first connecting rod 3 to move, thereby driving the support sleeve block 16 to move inward, so that the support sleeve block 16 slides on the main rod 17 and slides onto the auxiliary rod 12 to drive the ring sleeve 5 to move, so that the second spring 20 is compressed, which is convenient for secondary offsetting of the impact force, so that after multiple buffering, the vibration and direct collision of the drone body are eliminated, thereby increasing its service life and facilitating its use. When the drone accidentally falls into a watery place through the buoyancy balls 10 set around it, the buoyancy balls drive the drone to float on the water surface, thereby preventing the drone from sinking into the water, increasing practicality and reducing losses.

[0029] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
