Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle (UAV) anti-collision, and more specifically, to an unmanned aerial vehicle (UAV) anti-collision device. Background Art

[0002] Unmanned aerial vehicles, also known as "drones", are unmanned aircraft that are controlled by radio remote control equipment and self-contained program control devices, or are operated completely or intermittently autonomously by an on-board computer. Compared with manned aircraft, drones are often more suitable for tasks that are too "dull, dirty or dangerous". Drones can be divided into military and civilian use according to their application areas. In the military, drones are divided into reconnaissance aircraft and target aircraft. In the civilian sector, drones and industrial applications are the real rigid demand for drones. Currently, their applications in aerial photography, agriculture, plant protection, micro selfies, express delivery, disaster relief, wildlife observation, infectious disease monitoring, surveying and mapping, news reporting, power inspections, disaster relief, film and television shooting, and creating romance have greatly expanded the uses of drones themselves. Developed countries are also actively expanding industrial applications and developing drone technology.

[0003] In the existing technology, drone anti-collision usually adopts a fixed spherical device connected to the drone body to prevent collision. Therefore, on the one hand, the overall size of the drone becomes larger, making it impossible to enter and complete operations in some areas. On the other hand, the weight increases due to the increase in size, which makes the drone consume more electricity, thereby shortening the single use time of the drone and making it less convenient. Therefore, there is a need for a drone anti-collision device that is both easy to dismantle and can prevent collisions to reduce losses. Utility Model Content

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0032] In this utility model, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," "fixed," "provided with," "provided on," etc. should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; or internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on specific circumstances. Example

[0033] See also Figures 1-4 A UAV anti-collision device includes a UAV body 1, a plurality of evenly distributed arms 2 are provided at the side ends of the UAV body 1, a clamping piece 3 is installed at the tail end of the arm 2, a propeller 4 is installed at the upper end of the clamping piece 3, a connecting piece 5 is clamped between the lower inner walls of the clamping piece 3, and a protective piece 6 is fixedly connected to the side end of the connecting piece 5.

[0034] During use, this solution prevents existing drones from colliding with other surfaces due to improper operation during flight, causing damage to the drone's wings and propellers. In this embodiment, a protective member 6 larger than the driving range is placed under the drone's propeller. When improper operation is performed by the operator, the protective member 6 first contacts the object being collided with, thereby preventing damage to the propeller. Furthermore, if the drone collides with a horizontal wall and continues to fly, the protective member 6 can also rotate on the horizontal wall, reducing the impact force and squeezing sensation on the drone, ensuring that the drone still has strong stability in flight after the collision, thereby greatly improving the drone's protection.

[0035] At the same time, when the subsequent protective part 6 is damaged after the collision, the personnel can push the connecting part 5 from the bottom to the top in a snap-on pushing manner, so as to position the connecting part 5 inside the clamping part 3 or remove it from the inside of the clamping part 3, thereby facilitating the personnel to conveniently replace and disassemble the protective part 6.

[0036] See also Figures 1-2 and Figure 4 The clamping piece 3 includes a connecting sleeve 31 fixedly connected to the tail end of the arm 2, and a built-in groove 32 is provided at the lower end of the connecting sleeve 31. Two symmetrically distributed limiting grooves 33 are provided on the side wall of the built-in groove 32. A limiting column 34 is slidably connected between the inner walls of the limiting groove 33, and a spring 35 is fixedly connected between the limiting column 34 and the inner wall of the limiting groove 33.

[0037] More specifically, a pressure plate 36 is slidably connected between the inner top walls of the built-in groove 32 , and a second spring 37 is fixedly connected between the pressure plate 36 and the top wall of the built-in groove 32 .

[0038] More specifically, the connecting member 5 includes a fixing column 51 provided between the inner walls of the fixing member 3, the upper end of the fixing column 51 is fixedly connected to a connecting rod 52, the outer end of the connecting rod 52 is sleeved with two mirror-distributed positioning blocks 54, the upper end of the connecting rod 52 is fixedly connected to a limiting frame 53, and the side end of the fixing column 51 is fixedly connected to a plurality of connecting rods 55, and the connecting rods 55 are fixedly connected to the side wall of the protective member 6.

[0039] In the use process of the scheme, when the personnel need to replace the damaged protective part 6, the personnel first press upward the clamping column body 51, drive the connecting rod 52 and the limiting frame 53 to move upward, and at the same time, press the upper pressing plate 36 to drive the spring 2 37 to contract, and at the same time, the previous limiting column 34 is located between the limiting frame 53 and the positioning block 54, and with the upward movement of the clamping column body 51, the upper side of the positioning block 54 first touches the limiting column 34, drives the limiting column 34 to compress the spring 1 35 and make it stored in the limiting groove 33, until the limiting column 34 is located below the one side of the positioning block 54, and then pops out, at this time, the spring 2 37 is compressed by the pressing plate 36, and the limiting frame 53 and the positioning block 54 are located above the limiting column 34, and then the personnel pull down the clamping column body 51, drives the limiting column 34 to slide from the inclined surface below the positioning block 54 to the side surface of the limiting frame 53 under the touch and support force, so as to complete the disassembly of the connecting part 5 and the protective part 6 from the clamping part 3.

[0040] When the personnel install it later, they only need to press upward the clamping column body 51, drive the limiting frame 53 to first extrude the limiting column 34 to contract, and then one end of the limiting column 34 is clamped between the limiting frame 53 and the positioning block 54, drives the upper side of the limiting frame 53 to be limited to the upper side of the limiting column 34 by the touch force of the pressing plate 36 and the gravity, so as to complete the positioning and installation of the connecting part 5 and the protective part 6 in the clamping part 3.

[0041] Please refer to Figure 1 and Figure 4 , the protective part 6 comprises a protective frame 61 fixedly connected to the outer end of the connecting part 5, an air bag body 62 is installed on the inner wall of the protective frame 61, a plurality of evenly distributed connecting seats 63 are embedded and installed on the outer end of the protective frame 61, one end of the connecting seat 63 is in contact with the surface of the air bag body 62, and a rolling ball 64 is rotationally connected to the other end of the connecting seat 63.

[0042] More specifically, the protective frame 61 is made of carbon fiber material.

[0043] In the use process of the scheme, when the unmanned aerial vehicle is hit due to careless operation during flight, the protective frame 61 first blocks the internal protective propeller 4, avoiding the damage of the propeller 4, and at the same time, when serious impact is encountered, the impact force is resisted by the outer side of the protective frame 61 to the side of the air bag body 62, and due to the buffering performance of the gas after impact, the impact force generated when the unmanned aerial vehicle is hit can be greatly reduced, and the damage of the unmanned aerial vehicle is reduced.

[0044] In addition, when the unmanned aerial vehicle continuously contacts the impact surface, the rolling ball 64 rolls on the contact surface, thereby reducing the contact surface and the impact force when the unmanned aerial vehicle is hit, and ensuring the safety of the unmanned aerial vehicle.

[0045] The protective frame 61 is made of a hollow carbon fiber material, which has a relatively high rigidity, is hard and not easily deformed, and has a relatively small weight, which can further reduce the power loss of the drone.

[0046] The above-mentioned embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, which all fall within the scope of protection of the utility model. Therefore, the scope of protection of the utility model patent shall be based on the attached claims.
