[0043] Referring to Figure 1 and Figure 3In the present application, the shape of the umbrella cabin 100 can be cylindrical, polygonal or various irregular shapes, the cabin cover 120 can be a flat plate, a curved plate or a plate with an angle, and the opening 110 can be a flat surface, a curved surface or an angle surface. The cabin cover 120 can be fixed on the umbrella cabin 100 by means of adhesive, buckle or interference fit, and the cabin cover 120 will not fall off the umbrella cabin 100 due to air flow when the aircraft 200 is flying, and the cabin cover 120 will be pushed out of the umbrella cabin 100 by the internal force of the umbrella cabin 100 when the inflation mechanism 130 is inflated.

[0044] In some embodiments, the inflation mechanism 150 is located in the inflation mechanism 130, and the inflation mechanism 150 can release gas in the inflation mechanism 130, shorten the inflation time of the inflation mechanism 130, improve the time of the parachute ejected from the umbrella cabin 100, and improve the safety; By arranging the inflation mechanism 150 in the inflation mechanism 130, the air tightness requirement between the inflation mechanism 150 and the inflation mechanism 130 can be reduced, and the production cost and processing procedure can be reduced.

[0045] In some embodiments, the inflation mechanism 150 is installed on the inner side wall of the umbrella cabin 100, and the inflation mechanism 150 and the opening 110 are located on two opposite inner side walls of the umbrella cabin 100, respectively. The opening 110, the parachute body 140 and the inflation mechanism 150 are in the same direction, and when the inflation mechanism 150 inflates the inflation mechanism 130, the parachute body 140 can be subjected to a greater thrust of the inflation mechanism 130, which is beneficial to the parachute body 140 to be ejected from the umbrella cabin 100 faster and more smoothly; Preferably, the opening 110 and the parachute body 140 are in the gas outlet direction of the inflation mechanism 150.

[0046] Figure 4 is a sectional view of the parachute ejection device shown in the embodiments of the present application.

[0047] Referring to Figure 4 In some embodiments, the inflation mechanism 150 is installed on the bottom surface of the umbrella cabin 100, and the opening 110 faces obliquely upward; When the inflation mechanism 150 inflates the inflation mechanism 130, the inflation mechanism 130 expands upward and pushes the parachute body 140 out of the opening 110 in an obliquely upward direction.

[0048] In some embodiments, the inflating mechanism 150 is installed on the outer surface of the parachute cabin 100 or the aircraft 200, and the inflating mechanism 150 is in communication with the inflation mechanism 130 through the air pipe. The air pipe extends outward from the inflating mechanism 150, penetrates the shell of the parachute cabin 100 into the parachute cabin 100, and then penetrates the inflation mechanism 130 into the inflation mechanism 130. When the parachute body 140 needs to be ejected, the gas released by the inflating mechanism 150 enters the inflation mechanism 130 through the air pipe, the inflation mechanism 130 inflates and expands, and the parachute body 140 is ejected out of the parachute cabin 100.

[0049] In some embodiments, the inflating mechanism 150 can be a high-pressure gas cylinder, which stores compressed gas. The inflating mechanism 150 is provided with a gas outlet valve, and the inflating mechanism 150 releases gas to the inflation mechanism 130 through the gas outlet valve. The inflating mechanism 150 can be arranged in the inflation mechanism 130. The inflating mechanism 150 can also be arranged in the parachute cabin 100 between the shell of the parachute cabin 100 and the inflation mechanism 130. The inflating mechanism 150 can also be arranged outside the parachute cabin 100 and in communication with the inflation mechanism 130 through the air pipe. Specifically, the gas outlet valve is connected to the control system on the aircraft 200 through wired or wireless communication. When the aircraft 200 encounters an emergency situation, the control system on the aircraft 200 sends an instruction to the gas outlet valve, the gas outlet valve opens, the inflating mechanism 150 releases high-pressure gas, and the inflation mechanism 130 instantaneously expands and pushes the parachute body 140 out of the opening 110. Preferably, the inflation mechanism 130 is made of high-strength nylon, Kevlar, or rubber.

[0050] In some embodiments, the inflating mechanism 150 is a pyrotechnic launching type gas generating mechanism, and the inflating mechanism 150 is arranged in the inflation mechanism 130. The inflating mechanism 150 releases high-temperature and high-pressure gas to the inflation mechanism 130 through an electrochemical reaction. The inflation mechanism 130 has a bag-like structure, and is made of high-strength, high-temperature-resistant, flexible, and sealing textile fabric. Preferably, the inflation mechanism 130 is made of nylon or Kevlar, which ensures that the inflation mechanism 130 can withstand high-temperature and high-pressure gas generated by the inflating mechanism 150, avoids burning the internal structure of the parachute cabin 100, and thus enables the parachute cabin 100 to be recycled and reused, thereby reducing the cost of popularization and use.

[0051] Referring to Figure 4In some embodiments, the inflation mechanism 130 is provided with a mounting surface, and the inflation mechanism 130 is fixed to the inner side wall of the parachute cabin 100 through the mounting surface. The mounting surface and the opening 110 are respectively located on two opposite inner side walls of the parachute cabin 100. The opening 110, the parachute body 140 and the mounting surface are in the same direction. When the inflation mechanism 150 inflates the inflation mechanism 130, the inflation mechanism 130 expands to the parachute body 140 in a larger range, and the parachute body 140 can be subjected to a larger thrust of the inflation mechanism 130, which is beneficial to the parachute body 140 to be ejected from the parachute cabin 100 faster and more smoothly. Preferably, the opening 110, the parachute body 140 and the inflation mechanism 130 are in the gas outlet direction of the inflation mechanism 150, so that the inflation mechanism 130 expands to the parachute body 140 more quickly and more smoothly.

[0052] Referring to Figure 3 and Figure 4 In some embodiments, the inflation mechanism 130 is detachably connected to the parachute cabin 100 or the inflation mechanism 150, and the inflation mechanism 150 is detachably connected to the parachute cabin 100. Specifically, the inflation mechanism 130 can be fixed to the parachute cabin 100 or the inflation mechanism 150 by bolts, or the inflation mechanism 130 is hung on the parachute cabin 100 or the inflation mechanism 150 through a hanging ear sewn on the surface of the inflation mechanism 130; the inflation mechanism 150 is fixed in the parachute cabin 100 by bolts. After the aircraft 200 carrying the parachute ejection device is recovered, the inflation mechanism 130 can be detached from the parachute cabin 100, the inflation mechanism 150 can be detached from the parachute cabin 100, a new inflation mechanism 150 can be reinstalled in the parachute cabin 100, the original inflation mechanism 130 can be sleeved outside the inflation mechanism 150 or a new inflation mechanism 130 can be replaced, the unfolded parachute body 140 can be folded and put into the parachute cabin 100 or a new parachute body 140 can be replaced, the cabin cover 120 can be covered at the opening 110, and the parachute ejection device can be put into use again, so as to save the cost.

[0053] Referring to Figure 1 and Figure 3In some embodiments, the inflation mechanism 130 is folded and accommodated in the canopy 100, so as to reduce the space occupied by the inflation mechanism 130 inside the canopy 100, facilitate the design of the parachute ejection device to be smaller, and facilitate the installation of the parachute ejection device on the aircraft 200, and reduce the influence of the parachute ejection device on the shape and aerodynamics of the aircraft 200. In some embodiments, the inflation mechanism 130 is made of elastic material, and a part of gas can be reserved in the inflation mechanism 130. The inflation mechanism 130 forms a shape close to a sphere in the canopy 100, so that the inflation mechanism 130 presses the parachute body 140 on the canopy cover 120 and keeps the canopy cover 120 in a state of not being pushed out. When the inflation mechanism 150 inflates the inflation mechanism 130, the inflation mechanism 130 expands again, so as to generate pressure on the parachute body 140 and the canopy cover 120. The parachute body 140 directly pushes out the canopy cover 120 and is ejected out of the canopy 100, so as to reduce the distance of the parachute body 140 to the opening 110, reduce the time of the parachute being ejected, and improve the safety of the aircraft 200.
