[0002] Drones are being used more and more widely in modern society. However, during flight, drones may crash due to various reasons such as mechanical failure, signal interference, and operational errors. This can not only damage the drone itself, but also cause injury and loss to people and objects on the ground.

[0003] Based on the above, the inventors have discovered the following problem: current drones do not have crash protection features, which can easily lead to personal injury and property damage.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings to provide a crash-proof drone, in order to achieve a more practical value. Utility Model Content

[0005] The purpose of this utility model is to provide a crash-proof drone to solve the problem mentioned in the background art that current drones do not have crash-proof functions, which easily leads to personal injury and property damage.

A closing mechanism at the top of the box ensures that the top of the box is closed during normal flight, preventing accidental parachute deployment. A parachute opening mechanism is installed inside the second opening, providing power for the parachute to open rapidly. The sealing plate effectively closes the top of the box, protecting the parachute. A first connecting seat is installed at the output end of the electric telescopic rod, enabling automated control of the opening and closing of the sealing plate. A second connecting seat is slidably connected to the outside of the sliding rod, improving the stability of the sealing plate's movement. By having the output ends of a pair of electric telescopic rods facing opposite directions, a pair of sealing plates move in opposite directions, enabling the rapid and stable opening and closing of the top of the box. A blower installed on the inner side of the outer frame generates wind power to propel the parachute, accelerating its ejection and deployment from the box and increasing the success rate of parachute deployment. A drop sensor installed on one side of the top of the fixed frame monitors the drone's fall status in real time. When an abnormal fall is detected, a signal is sent to trigger the closing and parachute deployment mechanisms, enabling the parachute to open automatically, improving the timeliness and reliability of crash protection. The protective net is made of stainless steel, effectively resisting external environmental corrosion and ensuring long-term use without damage. This utility model effectively achieves crash protection, preventing personal injury and property damage caused by drone crashes, and has high practical value. Attached Figure Description

By increasing air resistance, this significantly reduces the drone's descent speed, preventing damage from a high-speed impact with the ground. A closing mechanism 107 at the top of the box 102 ensures that the top of the box 102 is closed during normal flight, preventing the parachute 106 from accidentally deploying. The parachute 106 pops outward, and an opening mechanism 103 is installed inside the second opening to provide power for its opening, enabling the parachute 106 to deploy rapidly in a short time. The sealing plate 10701 effectively seals the top of the box 102, protecting the parachute 106. A first connecting seat 10703 is installed at the output end of the electric telescopic rod 10702, enabling automated control of the opening and closing of the sealing plate 10701. A second connecting seat 10706 is slidably connected to the outside of the slide rod 10704, raising the sealing plate 10701. The stability of the 701 movement is achieved by having a pair of electric telescopic rods 10702 with their output ends facing opposite directions, causing a pair of sealing plates 10701 to move in opposite directions, thus enabling the rapid and stable opening and closing of the top of the box 102. A blower 10302 installed on the inner side of the outer frame 10301 generates wind power to provide power for the opening of the parachute 106, accelerating the ejection and deployment of the parachute 106 from the box 102 and improving the success rate of parachute opening. A drop sensor 108 installed on one side of the top of the fixed frame 101 monitors the drone's fall status in real time. When an abnormal fall is detected, a signal is sent in time to trigger the closing mechanism 107 and the parachute opening mechanism 103 to automatically open the parachute 106, improving the timeliness and reliability of crash protection. The protective net 104 is made of stainless steel, which can effectively resist the corrosion of the external environment and ensure that the protective net 104 will not be damaged during long-term use. This utility model can effectively achieve the crash protection function, avoiding personal injury and property loss caused by drone crashes, and has high practical value.
