Description

Drone Damage Prevention Device { DRONE DAMAGE PREVENTION DEVICE } The present invention relates to a drone damage prevention device, and more specifically, to a drone damage prevention device mounted to surround the exterior of a drone to prevent damage to the drone when an external force is applied. Recent advancements in drone technology are enabling roles beyond flight, including various missions, leisure sports, and transportation. However, as drone control technology is still in the early stages of development, there is a risk of component damage and loss due to aerial crashes and impacts. To prevent this, various drone damage prevention devices have been developed, but most have resulted in reduced output and control problems due to increased weight and obstruction of propeller flow. In addition, existing integrated anti-damage devices have the problem of reducing the portability of drones. Conventional drone damage prevention devices are mostly disposable, and repairs are performed using tape or adhesive, which significantly weakens durability and makes it difficult for the drone to perform at its best due to the unbalanced design. FIG. 1 is a perspective view of a drone damage prevention device according to an embodiment of the present invention, FIG. 2 is a photograph of a prototype of a drone damage prevention device according to an embodiment of the present invention, FIG. 3 is a side view of a drone damage prevention device according to an embodiment of the present invention before and after a load is applied. The drone damage prevention device of the present invention is mounted to surround the exterior of the drone to prevent damage to the drone, and as shown in FIGS. 1 and 2, it comprises an upper connecting plate (10), a lower connecting plate (20), an intermediate connecting plate (30), and an outer support (40). The upper coupling plate (10) is placed on the upper part of the drone (50). The lower coupling plate (20) is placed at the bottom of the drone (50). The above intermediate connecting plate (30) is positioned between the upper connecting plate (10) and the lower connecting plate (20) and has a larger diameter than the upper connecting plate (10) and the lower connecting plate (20). The drone (50) is connected to the middle part of the intermediate connecting plate (30). The above intermediate coupling plate (30) is equipped with a battery, motor, propeller, etc. Although propellers are not shown in Fig. 1, in the actual product, as shown in Fig. 2, multiple propellers are mounted on the intermediate coupling plate (30). The above outer support (40) is composed of an upper outer support (41) and a lower outer support (42). One end of the upper outer support member (41) is connected to the upper connecting plate (10) and the other end is connected to the intermediate connecting plate (30). One end of the lower outer support member (42) is connected to the intermediate connecting plate (30) and the other end is connected to the lower connecting plate (20). The above upper outer support (41) and lower outer support (42) are all made up of multiple units. As described above, the drone damage prevention device of the present invention is formed in a roughly spherical shape by means of the upper connecting plate (10), lower connecting plate (20), middle connecting plate (30), and outer support (40). The outer support member (40) may be assembled by integrally connecting the upper outer support member (41) and the lower outer support member (42) and penetrating the intermediate connecting plate (30). The above outer support (40) is made of steel wire and carbon fiber layer. The above steel wire is made of piano steel wire, etc., and has strong tensile strength and elastic modulus. Therefore, the above steel wire provides a force that restores the drone (50) to its original state after the impact disappears, after the drone rotates in a clockwise or counterclockwise direction due to strong tension and elastic modulus, and enables the drone damage prevention device to maintain a spherical shape. The carbon fiber layer is coated while wrapping around the steel wire. The above-mentioned carbon fiber layer is formed by mixing fine carbon fibers and nylon. Since the above carbon fiber layer is formed by mixing fine carbon fibers and nylon, not only can durability be significantly improved, but elasticity can also be increased. Depending on the case, the upper connecting plate (10), lower connecting plate (20) and intermediate connecting plate (30) may also be made of carbon fiber. The upper outer support (41) and lower outer support (42) may simply be formed in a curved shape along the outer surface of a spherical shape. That is, the outer support (40) can be formed in an arc shape that is convexly curved from the inside out. Preferably, as shown in FIG. 3, the upper outer support (41) is formed in a curved shape in one direction along the circumferential direction of the sphere, and the lower o
