[0019] like Figure 1-4 As shown, the present invention provides a drone protection device, including a drone body 1, a buffer mechanism 2 and a protection mechanism 3, wherein a device 4 is installed at the bottom of the drone body 1, a fixing column 11 is provided on the side of the device 4, a slide groove 111 is opened on the fixing column, the buffer mechanism 2 is arranged in the slide groove 111, the buffer mechanism 2 includes a slide bar 21 and a spring 22, the spring 22 is fixed on the inner wall of the slide groove 111, the slide bar 21 is slidably matched with the slide groove 111, the slide bar 21 is located directly below the spring 22, and the A fixing ring 1 23 and a fixing ring 231 are fixed to both ends of the slide bar 21, respectively. The fixing ring 1 23 and the fixing ring 231 are both slidably sleeved on the fixing column 11, and the fixing ring 1 is located below the fixing ring 231. The fixing ring 1 23 is fixedly connected to the bracket 24. The protection mechanism 3 is arranged on the side of the fixing column 11, and the protection mechanism 3 is rotatably connected to the fixing column 11. The protection mechanism 3 is slidably connected to the slide bar 21. When the bracket 24 contacts the ground, the protection mechanism 3 opens upward to form an umbrella shape to protect the bottom of the drone body 1.

[0020] The fixed column 11 is evenly distributed with four slide grooves 111 along the circumferential surface, and springs 22 are fixed on the inner walls of the slide grooves 111. Slide bars 21 are slidably matched in the slide grooves 111. The side of the slide bar facing outward is provided with an arc groove 211 that is slidably matched with the protection mechanism 3. The two sides of the slide groove 111 are respectively provided with fixed blocks 112 that are connected to the fixed column 11 as a whole. The fixed blocks 112 are rotatably connected with the protection mechanism 3. The bracket 24 has two and is symmetrically fixed on the outer side of the circumference of the fixed ring 23. The bracket 24 includes legs 241 and connecting plates 242. The legs 241 are connected to the fixed ring 23 through the connecting plates 242. The legs 241 are in a "return" shape. Through the provision of springs and slide bars, when the legs are in contact with the ground, the fixed column continues to move downward for a distance, and the springs are in contact with the slide bar and compressed, so that the drone body can be buffered.

[0021] The protection mechanism 3 includes a protection plate 31, a convex portion 311 and an adaptive flexible plate 32. The protection plate 31 is a fan-shaped structure. The convex portion 311 is fixed to one end of the protection plate 31 facing the slide bar 21. The two sides of the convex portion 311 are symmetrically fixed with cylindrical rods 1 3111, and the cylindrical rods 1 3111 are slidably matched with the arc groove 211. The two sides of the convex portion 311 between the protection plate 31 and the cylindrical rods 1 3111 are also symmetrically fixed with cylindrical rods 2 3112. The two cylindrical rods 2 3112 are respectively rotatably connected to the fixed block 112, and the adaptive flexible plate 32 is slidably inserted between the two protection plates 31. Through the provision of the protection plates, when the fixed column moves downward, the four protection plates will automatically open and form an umbrella shape, covering the bottom of the drone body, so that the bottom of the drone and the equipment carried are protected.

By setting the second spring and the adaptive flexible plate, the gap generated by the two protection plates during the movement can be closed, so that the protection plates can form an upward airflow during the movement, and the upward airflow acts on the drone body to provide an upward support force, so that the drone body is buffered.

[0023] There are a plurality of springs 3131 which are evenly distributed on the end surface of the adaptive flexible plate 32 .

[0024] Specific implementation and principle:

[0025] In actual application of the present invention, when the drone body 1 lands on an uneven ground from the air, the legs 241 first contact the ground, and the fixed column 11 at the bottom of the drone body 1 moves downward a short distance along the four slide bars 21. During the movement of the fixed column 11, the fixed column 11 drives the protective plate 31 rotatably connected to it through the cylindrical rod 2 3112 to rotate. During the rotation of the protective plate 31, the cylindrical rod 1 3111 on the protective plate 31 slides in the arc groove 211 on the slide bar 21. The arc groove 211 will limit the final opening angle of the protective plate 31 so that it can block the device 4 without touching it. To the device 4, since the four slide bars 21 are fixed to the fixing ring 1 23 and the fixing ring 2 231, the four slide bars 21 can move synchronously and enable the protection plate 31 to rotate synchronously and open upward to form an umbrella shape, thereby shielding and protecting the device 4 at the bottom of the drone body 1, and the adaptive flexible plate 32 slidably inserted between the two protection plates 31 can close the changing gap between the two protection plates 31 under the action of the spring 2 3131, and form an upward airflow in the process of opening the protection plate 31. The upward airflow acts on the drone body 1 with an upward support force, so that the drone body 1 is buffered again.

[0026] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the inventive concept and technical solution of the present invention, or the inventive concept and technical solution are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
