[0016] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] Reference Figures 1-3 This utility model provides an embodiment of a modular and detachable drone parachute assembly, including a fuselage 1, a frame 2 fixedly connected to the outside of the fuselage 1, a motor 3 fixedly connected inside the frame 2, a fan blade 4 connected to the output end of the motor 3, a mounting frame 5 fixedly connected inside the fuselage 1, a parachute body 6 snapped into the mounting frame 5, a fixing plate 7 fixedly connected to the outside of the parachute body 6, a fixing groove 8 opened inside the fixing plate 7, a fixing rod 9 slidably connected inside the mounting frame 5, one end of the fixing rod 9 snapped into the inside of the fixing groove 8, and a grip 10 fixedly connected to the other end of the fixing rod 9, with a spring-loaded component provided on the outside of the grip 10.

[0018] Specifically, motor 3 drives the fan blade 4 to rotate. The fixing slot 8 and fixing rod 9 cooperate with each other. One end of the fixing rod 9 is engaged inside the fixing slot 8 to fix the parachute body 6 within the mounting frame 5, preventing the parachute body 6 from shaking or shifting during drone flight. The fixing rod 9 provides a convenient operating component for the operator. By pulling the handle 10, the movement of the fixing rod 9 is controlled, thereby enabling the rapid installation of the parachute body 6.

[0019] Reference Figure 4 and Figure 5 The rebound assembly includes a rebound rod 11, one end of which is fixedly connected to the outside of the grip 10, and the outside of the rebound rod 11 is slidably connected to the inside of the mounting frame 5. A spring 12 is provided between the rebound rod 11 and the mounting frame 5.

[0020] Specifically, the mounting frame 5 is used to limit the movement direction of the rebound rod 11 to prevent it from deviating or tilting during sliding. When the operator pulls the grip rod 10 to install the parachute body 6, the grip rod 10 will drive the rebound rod 11 to slide away from the mounting frame 5. At this time, the rebound rod 11 will generate a tensile force on the spring 12, causing the spring 12 to store elastic potential energy. After the parachute body 6 is placed in the mounting frame 5, the operator releases the grip rod 10, and the spring 12 will release the stored elastic potential energy, pushing the rebound rod 11 back to its original position in the mounting frame 5. The rebound rod 11 then drives the grip rod 10 and the fixing rod 9 to reset synchronously, allowing the fixing rod 9 to be inserted into the fixing groove 8, thus simplifying the installation process of the parachute body 6.

[0021] Reference Figure 4and Figure 5 A lower plate 13 is fixedly connected to the lower surface of the fuselage 1. A starting rod 14 is slidably connected inside the fuselage 1, and the outside of the starting rod 14 is slidably connected inside the mounting frame 5. The top of the starting rod 14 is magnetically connected to the rope inside the parachute body 6. A second spring 15 is provided at the bottom of the starting rod 14, and a compression airbag 16 is provided at the bottom of the second spring 15. The outside of the compression airbag 16 is fixedly connected to the inside of the lower plate 13. An airbag bag 17 is provided at the release port of the compression airbag 16, and the outside of the airbag bag 17 is installed inside the motor 3. Multiple plastic hard sheets 18 are fixedly connected inside the lower plate 13.

[0022] Specifically, the top of the activation lever 14 is magnetically connected to the rope inside the parachute body 6. Normally, it stably holds the parachute rope, preventing it from swaying inside the fuselage 1. When a drone malfunction triggers parachute deployment, the parachute rope pulls the activation lever 14 upwards. As the activation lever 14 slides upwards, it simultaneously stretches spring 15, storing elastic potential energy. Spring 15 then acts on the compressed airbag 16 at the bottom, rapidly releasing high-pressure gas to inflate and expand the airbag bag 17, wrapping around the bottom of the motor 3 to form a flexible buffer layer. When the compressed airbag 16 inflates and pushes the airbag bag 17 to expand, the expansion force of the airbag bag 17 can push open the plastic rigid sheet 18 without hindering the deployment of the airbag bag 17. Simultaneously, the rigidity of the plastic rigid sheet 18 also enhances the overall structural strength of the lower plate 13, preventing it from easily shattering during landing impact.

[0023] Working principle: When it is necessary to install the parachute body 1, the fixed rod 9 is moved by pulling the grip 10, and the parachute body 6 is placed in the mounting frame 5. After releasing the grip 10, the spring 12 in the rebound assembly will push the rebound rod 11 to reset, thereby driving the fixed rod 9 to be inserted into the fixing groove 8 of the fixing plate 7, so as to achieve stable fixation of the parachute body 6 in the mounting frame 5. When the drone malfunctions and deploys its parachute, the parachute body 6 is magnetically connected to the activation lever 14. When the parachute body 6 is released, it will cause the activation lever 14 to move upward. At this time, the second spring 15 will be pulled to extend, and the other end of the second spring 15 will activate the compression airbag 16. The compression airbag 16 will inflate the airbag bag 17 and push open multiple plastic hard plates 18 to reduce the impact force during the drone's descent and protect the fuselage 1 and internal components.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
