[0035] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] like Figure 1-4As shown, a carbon fiber drone includes a drone body 1, a wing frame 2, a propeller 3, a connecting rod 4, a storage box 5, and a buffer mechanism. The drone body 1 is made of carbon fiber material and has a motor and connecting belt inside to drive the propeller 3. The wing frame 2 is made of carbon fiber material and is evenly arranged around the drone body 1 and fixed to the side wall of the drone body. The propeller 3 is rotatably connected to the wing frame 2 via a shaft. The connecting rod 4 is evenly arranged on the bottom of the drone body and one end is fixed to the bottom of the drone body 1. The storage box 5 is fixed to the connecting rod 4 and is used to place items. It has an opening and a rotatable sealing door 51 at the opening.

[0037] Specifically, the buffer mechanism is correspondingly set on the end of the connecting rod 4. Each buffer mechanism includes a connecting plate 61, a support plate 62, a support column 64, an elastic telescopic member 65, and a protective component. The connecting plate 61 is fixed on the bottom end of the connecting rod 4; the support plate 62 is located directly below the connecting plate 61; the support column 64 is fixed on the support plate 62; the elastic telescopic member 65 is evenly arranged around the support column 64, with one end of the elastic telescopic member 65 hinged to the support column 64 and the other end hinged to the connecting plate 61. The buffer mechanism is correspondingly set on the end of the connecting rod 4. When the drone lands, the support plate 62 contacts the ground first, and the impact force is transmitted to the elastic telescopic member 65 through the support column 64. The elastic telescopic member 65, through the hinge structure at both ends, undergoes expansion and contraction deformation under the action of the impact force, converting the vertical impact force into elastic potential energy, thereby buffering the impact on the drone body 1 and the storage box 5. The buffer mechanism effectively absorbs the impact force during landing, solving the problem that traditional drone support frames are easily damaged by inertial forces, protecting the drone body 1 and the carried items, and extending the service life of the drone, especially suitable for heavy-load flight scenarios.

[0038] As a preferred embodiment, the elastic telescopic component 65 includes a sleeve 651, a first elastic element 652, and a telescopic rod 653. One end of the sleeve 651 is hinged to the support column 64. The first elastic element 652 is a spring, with one end fixed inside the sleeve 651. One end of the telescopic rod 653 is fixed to the end of the first elastic element 652, and the other end is hinged to the connecting plate 61, and it can slide relative to the inner wall of the sleeve 651. The elastic telescopic component 65 is composed of the sleeve 651, the first elastic element 652 (such as a spring), and the telescopic rod 653. When subjected to impact force, the telescopic rod 653 slides relative to the sleeve 651, compressing or stretching the first elastic element 652 inside the sleeve 651. The first elastic element 652 absorbs energy through deformation, thus achieving buffering.

[0039] As a preferred embodiment, the elastic telescopic member 65 is fitted with a second elastic member 66, which is a spring. Both ends of the second elastic member 66 are fixed to both ends of the elastic telescopic rod 653. The second elastic member 66 is fitted outside the elastic telescopic member 65, with both ends fixed to both ends of the elastic telescopic member 65. When the elastic telescopic member 65 extends or retracts, the second elastic member 66 is simultaneously stretched or compressed, deforming together with the first elastic member 652 to form a double elastic buffer.

[0040] As a preferred embodiment, the protective component includes a mounting groove 641, a third elastic element 67, and a rubber block 68. The mounting groove 641 is formed on the support column 64. The third elastic element 67 is a spring, one end of which is fixed inside the mounting groove 641. The rubber block 68 is fixed on the end of the third elastic element 67, and it can slide relative to the inner wall of the mounting groove 641, with a portion of it extending out of the mounting groove 641.

[0041] In other embodiments, the storage box 5 is provided with a pressure plate 52, which can move up and down relative to the connecting rod 4; a fourth elastic element 53 is sleeved on the connecting rod 4, the fourth elastic element 53 is a spring, one end of the fourth elastic element 53 is connected to the pressure plate 52, the fourth elastic element 53 is sleeved on the connecting rod 4, and the other end is connected to the pressure plate 52. Through its own elastic deformation, it applies continuous pressure to the pressure plate 52, so that the pressure plate 52 is always in close contact with the item; when the item shakes slightly, the fourth elastic element 53 buffers the movement through deformation, maintaining the pressed state of the pressure plate 52; the outer wall of the connecting rod 4 is provided with threads, and an adjusting nut 54 is screwed onto the connecting rod; a slider 55 is sleeved on the connecting rod 4, the slider 55 can slide up and down relative to the connecting rod 4, and one side of the slider 55 is connected to the fourth elastic element 53; the connecting rod 4... The outer wall is threaded with an adjusting nut 54. Rotating the adjusting nut 54 can move the slider 55 up and down. The slider 55 is connected to the fourth elastic element 53. The change in the position of the slider 55 changes the compression of the fourth elastic element 53, thereby adjusting the pressure of the pressure plate 52 on the object. The pressure plate 52 is provided with a rubber plate 56. The rubber plate 56 at the bottom of the pressure plate 52 is in direct contact with the object. The softness of the rubber avoids hard contact damage to the surface of the object caused by the pressure plate 52. At the same time, the high friction of the rubber can enhance the grip on the object. The rubber plate 56 is provided with anti-slip protrusions 57. The anti-slip protrusions 57 on the rubber plate 56 increase the contact friction with the surface of the object, further preventing the object from sliding under the pressure plate 52. Especially when the drone is bumpy or stops suddenly, it can effectively limit the displacement of the object.
