[0024] Regarding the foregoing and other technical contents, features and effects of the present utility model, they will be clearly presented in the following detailed description in conjunction with the Figure 1-6 reference to the embodiments. The structural contents mentioned in the following embodiments are all with reference to the accompanying drawings of the specification.

[0025] Next, various exemplary embodiments of the present utility model will be described with reference to the drawings.

[0026] Embodiment 1, a recovery parachute cabin for a rear-pushing unmanned aerial vehicle with stable parachute opening, comprising a cabin body 1 and a parachute pack body 2, characterized in that:

[0027] The cabin body 1 is provided with a parachute pack placement groove 3 and a heavy object placement groove 4, and a cabin cover plate 5 is detachably connected to the top;

[0028] The parachute pack body 2 is arranged in the parachute pack placement groove 3, a traction rope 6 is arranged at the bottom of the parachute pack body 2, and the traction rope 6 is fixedly connected with the cabin body 1;

[0029] A gas reaction device 7 is arranged in the heavy object placement groove 4, a parachute-pulling heavy object 8 is sleeved on the gas reaction device 7, and a cable 9 matched with the gas reaction device 7 is arranged on the cabin body 1;

[0030] A connecting belt 10 is arranged between the parachute-pulling heavy object 8 and the parachute pack body 2;

[0031] A reinforcing plate 11 is arranged at the bottom of the cabin body 1, a lifting ring 12 is arranged on the reinforcing plate 11, and the lifting ring 12 is connected with the traction rope 6;

[0032] There are four groups of the lifting rings 12, and they are evenly distributed on the reinforcing plate 11. There are four groups of traction ropes 6 at the bottom of the parachute pack body 2, and the four groups of traction ropes 6 are respectively connected with the four groups of lifting rings 12;

[0033] The cabin body 1 and the reinforcing plate 11 are connected by positioning screws;

[0034] The cabin cover plate 5 and the cabin body 1 are connected by a buckle;

[0035] The cabin body 1 is made of carbon fiber material, and the cabin cover plate 5 is made of ABS injection molding material.

[0036] During use, the cabin body 1 is arranged on the unmanned aerial vehicle. When recovery is needed, an electric signal is sent to the gas reaction device 7 through the controller. Under the action of the gas reaction device 7, the parachute-pulling heavy object 8 and the folded parachute pack body 2 are launched. Under the action of the gas reaction device 7, the parachute-pulling heavy object 8 pushes open the cabin cover plate 5. After the parachute pack body 2 is launched, the parachute pack body 2 is affected by the airflow and unfolds in the air, completing the deceleration recovery work of the unmanned aerial vehicle;

[0037] Using tools to remove the positioning screws, the reinforcing plate 11 can be removed. Since the parachute pack body 2 and the lifting ring 12 are connected by the traction rope 6, and the lifting ring 12 is arranged on the reinforcing plate 11, by removing the positioning screws, the internal parts can be quickly replaced, and the overall replacement of the cabin can be completed within three minutes, enabling the unmanned aerial vehicle to carry out work again;

[0038] The gas reaction device 7 is placed inside the parachute compartment, reducing the occupation of external space. However, by reasonably distributing the proportion of the parachute pack placement groove 3 and the heavy object placement groove 4, the utilization rate of the parachute compartment space can be improved, and the size of the gas reaction device 7 can be optimized as much as possible to reduce the occupation of the internal parachute compartment space;

[0039] The gas reaction device can adopt a gunpowder device to launch the parachute pulling heavy object 8 through the generated impact force.

[0040] The above description is only for explaining the present invention, and it should be understood that the present invention is not limited to the above embodiments. All various flexible forms conforming to the idea of the present invention are within the protection scope of the present invention.
