[0025] The sealing plate 13 is arranged at the lower end inside the air cylinder 8, the connecting pipeline 6 is fixedly installed at the lower end outside the air cylinder 8, one end of the connecting pipeline 6 is fixedly installed with the protective air bag 5, the installation of the protective air bag 5 can make the anti-collision support 9 move inside the air cylinder 8, the air inside the air cylinder 8 enters the inside of the protective air bag 5 through the connecting pipeline 6, and then the protective air bag 5 is inflated, so that the propeller part 4 of the unmanned aerial vehicle is prevented from being damaged by severe impact, and the protection capability of the device is enhanced. The center of the lower end of the unmanned aerial vehicle shell 1 is installed with the counterweight battery compartment 2, the installation of the counterweight battery compartment 2 can adjust the gravity center of the device, so that when the device does free fall, the counterweight battery compartment 2 is heavier and can drive the unmanned aerial vehicle shell 1 to overturn, so that the side of the unmanned aerial vehicle shell 1 installed with the anti-collision support 9 is in contact with the ground, so that when the device collides with the ground, the lower top spring 12 can be smoothly compressed and rebounded. The counterweight battery compartment 2 is fixedly connected with the unmanned aerial vehicle shell 1.

[0026] Please refer to Figure 1 、 Figure 2 、 Figure 3 And Figure 4 The extension arm 3 is installed around the outside of the unmanned aerial vehicle shell 1, the extension arm 3 is fixedly connected with the unmanned aerial vehicle shell 1, the upper end of the extension arm 3 is fixedly installed with the unmanned aerial vehicle propeller part 4, the unmanned aerial vehicle propeller part 4 is fixedly connected with the protective air bag 5, the lower end of the anti-collision support 9 is installed with the rubber pad 10, the installation of the rubber pad 10 can slide the unmanned aerial vehicle when the unmanned aerial vehicle is placed on the table, the rubber pad 10 is fixedly connected with the anti-collision support 9, the limiting boss 11 extends into the inside of the limiting sliding groove 14, the lower top spring 12 is fixedly connected with the anti-collision support 9 and the anti-collision cylinder 7, the sealing plate 13 is fixedly connected with the air cylinder 8, the connecting pipeline 6 penetrates through the extension arm 3, and the sealing plate 13 is slidably connected with the anti-collision support 9 through the clamping groove.

[0027] Working principle: When the drone encounters sudden severe weather or improper operation, it may fall and undergo freefall. Under the weight of the counterweight battery compartment 2, the side of the drone shell 1 with the anti-collision bracket 9 faces the ground. When the anti-collision bracket 9 contacts the ground, it compresses the lower spring 12 upwards, causing the spring 12 to retract. This, in turn, moves the anti-collision bracket 9 upwards, allowing the limiting boss 11 on the outside of the anti-collision bracket 9 to slide within the limiting groove 14. Then, the lower spring 12 extends, causing the anti-collision bracket 9 to move downwards, thus causing the device to jump upwards. The drone then restarts and can take off again. During the downward movement, the anti-collision bracket 9 will force the air inside the air cylinder 8 into the protective airbag 5 through the connecting pipe 6, thereby inflating the protective airbag 5 to protect the drone propeller component 4 and prevent damage to it. After the staff retrieves the drone, they only need to push the anti-collision bracket 9 upward to make the limiting protrusion 11 on the outside of the anti-collision bracket 9 re-lock into the limiting slide groove 14 to reset the device. It should be noted that when the device is normally picked up and put down, the pressure on the anti-collision bracket 9 is insufficient to overcome the elastic force of the lower spring 12 and move the anti-collision bracket 9 upward. Only the force generated when the device collides with the ground can overcome this force. The elastic force of the top spring 12 causes the anti-collision bracket 9 to move upward. The device also has a bottom spring 12 that can push the anti-collision bracket 9 downward. When the device falls to the ground, the anti-collision bracket 9 impacts the ground, causing it to push the bottom spring 12 upward. This compresses the bottom spring 12, causing the limiting boss 11 on the outside of the anti-collision bracket 9 to slide inside the limiting groove 14. This releases the limiting groove 14 from the limiting boss 11, allowing the bottom spring 12 to extend. This causes the anti-collision bracket 9 to extend from inside the air supply cylinder 8 and the anti-collision cylinder 7, causing the device to spring upward and suspend the drone in the air, facilitating its re-takeoff and preventing further damage. The outer shell 1 contacts the ground to prevent damage to the drone outer shell 1. The installation of the protective airbag 5 allows air from inside the air supply cylinder 8 to enter the protective airbag 5 through the connecting pipe 6 when the anti-collision bracket 9 moves inside the air supply cylinder 8, thereby causing the protective airbag 5 to inflate and prevent the drone propeller component 4 from being severely impacted and damaged, thus enhancing the protective capability of the device. The installation of the counterweight battery compartment 2 can adjust the center of gravity of the device, so that when the device is in free fall, the heavier counterweight battery compartment 2 will cause the drone outer shell 1 to flip, so that the side of the drone outer shell 1 with the anti-collision bracket 9 contacts the ground, ensuring that the lower top spring 12 can be compressed and rebound smoothly when the device collides with the ground.
