[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please see Figure 1-4 As shown, this utility model is a parachute protection device for unmanned aerial vehicles (UAVs), including a UAV fuselage 1, an unmanned aerial vehicle (UAV) support frame 2 connected to the side of the UAV fuselage 1, and UAV propellers 3 connected to the top of the UAV support frame 2. A parachute compartment 4 is attached to the top of the UAV fuselage 1. A parachute filling compartment 5 is provided on one side of the parachute compartment 4 and connected to it. A support plate 11 for supporting the parachute filling compartment 5 and the bottom of the detonation chamber 10 is fixed to the bottom of the parachute compartment 4. The parachute filling compartment 5 is equipped with a parachute body 9. The parachute compartment 4 contains a barometric altimeter, attitude sensor, and accelerometer to monitor the UAV's flight status in real time. It also includes a positioning module for real-time... The system displays the entire parachute protection period and the drone's location. It includes a built-in power supply and control module. A recessed parachute compartment 7 is located at the top of the parachute filling compartment 5. The parachute body 9 is placed inside the compartment 7, and is adhered to the wall of the compartment 7 via adhesive at the center of the bottom. The parachute body 9 is then pressed onto the explosive ejector 8. The opening at the top of the compartment 7 is secured by a cover plate 6. Notably, the cover plate 6 is forced open after the parachute body 9 deploys, allowing it to unfold and form the parachute. The parachute body 9 is made of 20D-grade high-toughness, lightweight fabric with a special smooth and dense coating to aid in the drone's slow descent. A wire groove is located at the bottom of the compartment 7, into which red and black wires are inserted. These wires connect to a triggering device inside the detonation chamber 10 to detonate the explosive ejector 8. This device is connected to the control module. This detonation method is existing technology.

[0024] The surface of the parachute filling chamber 5 is fixedly connected to the detonation chamber 10, and the detonation chamber 10 and the parachute filling chamber 5 are stepped. A slot is opened on the surface of the parachute functional chamber 4 to allow the detonation chamber 10 to be inserted. The detonation chamber 10 is inserted laterally into the slot, so that the surfaces of the parachute functional chamber 4 and the parachute filling chamber 5 are in contact to complete the installation. In order to maintain a high connection, a locking mechanism is provided between the parachute functional chamber 4 and the parachute filling chamber 5. The locking mechanism includes a positioning support rod 12, a rotating shaft 13, a support positioning rod 14, and a through hole 15. The rotating shaft 13 is rotatably connected to the side of the parachute filling chamber 5, the support positioning rod 14 is fixed to the side wall of the parachute functional chamber 4, the positioning support rod 12 is fixed to the end face of the rotating shaft 13, and the through hole 15 is opened on the side of the positioning support rod 12. The perforated part 15 is inserted and adapted. The end of the support positioning rod 14 is provided with the perforated part 15, and the bent part of the support positioning rod 14 is attached to the top of the positioning support rod 12. When the parachute filling chamber 5 approaches the parachute functional chamber 4, the rotating shaft part 13 and the positioning support rod 12 move synchronously toward the support positioning rod 14. After the detonation chamber 10 is completely submerged in the slot of the parachute functional chamber 4, the rotating shaft part 13 is rotated toward the support positioning rod 14, so that the end of the positioning support rod 12 is attached to the bent part of the support positioning rod 14. Then the support positioning rod 14 is inserted into the perforated part 15, and the threaded part of the support positioning rod 14 protrudes upward from the perforated part 15. At this time, the positioning support rod 12 is limited and locked by screwing the nut into the threaded part. At this time, the connection strength between the parachute functional chamber 4 and the parachute filling chamber 5 can be strengthened. Meanwhile, before the positioning rod 12 falls into the support positioning rod 14, a strap collar 16 can be fitted onto the positioning rod 12. After the nut is screwed into the threaded part of the support positioning rod 14, the strap collar 16 can be assembled simultaneously. The assembled strap collar 16 is wrapped around the body of the drone body 1. It is worth noting that when the restraint strap 17 is tied to the body of the drone body 1, it should not cover the sensors of the drone body 1 itself.

[0025] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
