[0031] The present invention provides a drone, aiming to solve the problem that the drone body is easily deformed and damaged, resulting in a short lifespan of the drone.

[0032] Please refer to Figure 1 、 Figure 2 and Figure 4In one embodiment of the present invention, the drone 300 includes a frame 200 and several corner guards 100. The corner guards 100 are arranged at the corners of the frame 200. The side of the corner guards 100 facing the frame 200 is provided with a first card slot 11 for clamping the corner guards 10 on the frame 200. In this embodiment, the corner guards 100 are clamped on the frame 200 through the first card slot 11. By arranging the corner guards 10 at the corners of the frame 200, when the drone 300 lands on the ground, the corner guards 100 of the drone 300 are first hit. The corner guards 100 buffer the impact force of the ground, effectively protecting the fuselage of the drone 300, thereby reducing the deformation of the drone 300 caused by the impact, and extending the service life of the drone 300. Further, referring to Figure 1 , corner guards 100 are provided at the four corners of the frame 200, so that the drone 300 can be protected no matter which direction it lands from. Specifically, the number of corner guards 100 can be designed according to actual needs and is not limited here.

[0033] As a preferred embodiment, refer to Figure 4 The rack 200 includes two brackets (not shown) that are arranged in parallel and spaced apart. The number of first slots 11 is two, and the two first slots 11 are provided in a one-to-one correspondence with the two brackets. By providing two first slots 11 that are arranged in parallel and spaced apart on the side of the corner protector 100 that faces the rack 200, and the first slots 11 are provided to match the two brackets that are arranged in parallel and spaced apart on the rack 200, the corner protector 100 is more firmly fixed on the rack 300. It is understood that the number of first slots 11 can also be multiple, specifically designed according to the structure of the rack 200. For example, when the rack 200 includes three brackets that are arranged in parallel and spaced apart, the number of first slots 11 is also set to three, and the three first slots 11 are provided in a one-to-one correspondence with the three brackets, thereby ensuring that the corner protector 100 is firmly fixed on the rack 200.

[0034] In the above embodiment, referring to Figure 4 and Figure 5 A support (not shown) for connecting the two supports is provided between the two supports. A second slot 12 for accommodating the support is provided on the side of the corner guard 100 facing the frame 200. The second slot 12 is connected to the two first slots 11. Figure 1The second slot 12 is provided to engage the two bracket posts. When the corner protector 100 is secured to the rack 200 through the engagement of the first slot 11 with the bracket, the second slot 12 engages the post, further tightening the connection between the corner protector 100 and the rack 200. It should be noted that in other embodiments, the engagement of the second slot 12 with the post can also be designed as a buckle engagement with the post. That is, a buckle is provided on the corner protector 100 to engage the post, and the buckle engages the post, thereby securing the corner protector 100 to the rack 200.

[0035] In addition, as a more preferred embodiment, referring to Figure 4 A third slot 13 is provided on the inner wall of the first slot 11 near the second slot 12. The third slot 13 cooperates with the first slot 11 to clamp the corner protector 100 on the frame 200. Figure 1 and Figure 2 When the corner protector 100 is matched with the rack 200, the two first card slots 11 are clamped onto the two parallel and spaced brackets of the rack 200, and the third card slot 13 on the inner wall of the first card slot 11 close to the second card slot 12 is simultaneously clamped into the bracket, and cooperates with the first card slot 11 to clamp the corner protector 100 onto the rack 200.

[0036] Preferably, a support portion 14 is provided on the side of the corner protector 100 and the first slot 11, and the support portion 14 is overlapped on the frame 200. Figure 1 and Figure 4 The support portion 14 overlaps the frame 200, making the corner protector 100 more stably connected to the frame 200. The support portion 14 is designed as a trapezoidal boss structure, which makes the structure more beautiful. Secondly, the trapezoidal boss design of the support portion 14 cooperates with the curved surface of the back of the corner protector 100 facing away from the frame, making the corner protector 100 engage with the frame 200 and the structure more stable. Of course, in other embodiments, the shape of the support portion 14 can also be designed as a triangular boss or a square boss, etc.

[0037] Furthermore, there are two protective portions, symmetrically positioned at either end of the corner guard. The two protective portions 14 are respectively attached to the two brackets of the frame. Designing two such protective portions not only makes the structure more stable, but also ensures that when the drone 300 is struck by the ground, whether on the top or bottom, the corner guard 100 first contacts the impacting object, effectively protecting the drone 300.

[0038] In addition, a more preferred embodiment of the previous embodiment is that the upper end surface of the corner protector 100 protrudes from the upper end surface of the frame 200, and the lower end surface of the corner protector 100 protrudes from the lower end surface of the frame 200. In this case, whether the top or bottom surface of the drone 300 strikes an obstacle, the upper or lower end surface of the corner protector 100 will first contact the impacting object, ensuring that the corner protector 100 is the first to be struck, further protecting the drone 300.

[0039] Preferably, the corner protectors 100 in the embodiments of the present invention are made of a flexible material, such as rubber, plastic, or silicone. Flexible materials offer advantages such as high elasticity, the ability to recover after deformation, and wear resistance. Using flexible materials to construct the corner protectors 100 can absorb the force exerted by the drone 300 upon impact, thereby mitigating the impact and minimizing damage to the drone 300.

[0040] As a preferred embodiment of the present invention, refer to Figure 1 and Figure 3 The back of the corner protector 100, which faces away from the first slot 11, is an arcuate surface. Specifically, the back of the drone corner protector 100, which faces away from the frame 200, is an arcuate surface. The back of the corner protector 100 adopts a three-stage arched design. That is, when the corner protector 100 is upright, the size of the upper and lower ends of the corner protector 100 is smaller than the size of the middle portion of the corner protector 100. This design of the corner protector with small ends and a large middle portion can effectively concentrate the force of the drone hitting the ground on the back. At the same time, the method of designing the back of the corner protector as an arcuate surface can also concentrate the force of the impact on the back, rather than directly transmitting it to the drone 300. At the same time, it is ensured that when the drone 300 falls in the extreme state parallel to the ground, the corner protector 100, rather than the drone 300, will first touch the ground.

[0041] Furthermore, the motor (not shown) of drone 300 is mounted inside frame 200, which is equipped with a support bar 21. One end of the support bar 21 is connected to the motor, and the other end is fixed to frame 200. Using the motor as part of the stabilizing structure reduces the weight of drone 300, eliminates the need for a central stabilizing member on the entire frame 300, and makes the structure more compact.

[0042] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention description and drawings under the concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
