[0002] Unmanned aerial vehicles, also known as "drones", are unmanned aircraft that are controlled by radio remote control equipment and self-contained program control devices, or are operated completely or intermittently autonomously by on-board computers.

[0003] Drones usually fly by driving the propellers at high speed through motors, but most drones on the market usually lack devices to protect the propellers. Once a drone loses its signal, it will make an emergency landing, and during the forced landing, the propellers may collide with surrounding trees or buildings. Once a collision occurs, the propellers will be damaged. In serious cases, the drone may crash or explode, resulting in property loss. Utility Model Content

[0022] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a drone with an anti-fall guard frame, including a drone body 1, on which a protective mechanism 2 for protecting the drone blades is arranged. The protective mechanism 2 can protect the blades of the drone body 1 to prevent the drone body 1 from colliding with the blades during flight or when an emergency landing occurs. A supporting mechanism 3 is arranged on the protective mechanism 2. The supporting mechanism 3 can make the drone body 1 float on the water surface to prevent the drone body 1 from falling into the water when an emergency landing occurs.

[0023] The upper protection mechanism 2 includes a support rod 21, a No. 1 electric push rod 22, a connecting rod 23, a protection frame 24, and a connecting rod 25; the support rod 21 is fixedly mounted on the outer wall of the drone body 1, and a protection frame 24 is hinged on the top of the support rod 21. The protection frame 24 is provided with two groups, and the two groups of protection frames 24 are mirror-set on the top of the support rod 21 with the No. 1 electric push rod 22 as the central axis. The shape of the protection frame 24 is "L"-shaped, and the protection frame 24 is rotated to the top of the blade on the side of the drone body 1. The protection frame 24 can be used to protect the blade to avoid To prevent the propeller blades of the drone body 1 from colliding during flight or in the event of an emergency landing, a connecting rod 25 is fixedly installed on the outer wall of the protective frame 24. When the connecting rod 23 pushes the connecting rod 25, the protective frame 24 can be driven to rotate on the top of the support rod 21. The No. 1 electric push rod 22 is fixedly installed on the outer wall of the drone body 1, one end of the connecting rod 23 is hinged to the piston end of the No. 1 electric push rod 22, and the other end of the connecting rod 23 is hinged to the outer wall of the connecting rod 25. The No. 1 electric push rod 22 is started to push the connecting rod 23, so that the connecting rod 23 pushes the connecting rod 25.

[0024] The above-mentioned supporting mechanism 3 includes a floating plate 31 and a No. 2 electric push rod 32; the floating plate 31 is hinged on the outer wall of the protective frame 24, and is rotated to a horizontal state on the outer wall of the protective frame 24 by the floating plate 31. When the UAV body 1 makes an emergency landing on the water, the floating plate 31 can be used to make the UAV float on the water surface to prevent the UAV body 1 from falling into the water, and the UAV is fully protected so that the UAV body 1 can fly safely in the wild. The outer wall of the protective frame 24 is hinged with a No. 2 electric push rod 32, and the piston end of the No. 2 electric push rod 32 is hinged on the outer wall of the floating plate 31. Starting the No. 2 electric push rod 32 can push the floating plate 31 to rotate the floating plate 31 on the outer wall of the protective frame 24.

The propeller blades can be protected by the protective frame 24 to prevent the propeller blades of the UAV body 1 from colliding during flight. Moreover, when the UAV body 1 loses signal and makes an emergency landing, the protective frame 24 can be used to protect the propeller blades to prevent the propeller blades from colliding and causing damage to the UAV body 1.

[0026] When the protective frame 24 is located directly above the blades on the side of the drone body 1, the No. 2 electric push rod 32 is started to push the floating plate 31, so that the floating plate 31 rotates to a horizontal state on the outer wall of the protective frame 24. When the drone body 1 makes an emergency landing on the water, the floating plate 31 can be used to make the drone float on the water surface to prevent the drone body 1 from falling into the water, thereby fully protecting the drone and allowing the drone body 1 to fly safely in the wild.
