Description

Technical Field

[0001] The invention relates to a fast-opening parachute. Background Art

[0002] A parachute generally consists of a main parachute body, a parachute bag and a guide parachute. When in use, the main parachute body is pulled out of the parachute bag by the guide parachute. Under the action of wind, the main parachute body is opened.

[0003] The main parachute can only play a good deceleration role when it is fully opened. It takes a certain amount of time for the main parachute to be fully opened. In the case of a relatively low altitude, if the main parachute cannot be fully opened in time, it will cause the user to fall to the ground. Therefore, it is necessary to increase the speed of the main parachute opening.

[0004] In response to the above technical problems, application number CN201720572410.2 discloses a parachute with a rapid opening function, which improves the opening speed by optimizing the main parachute rope connection structure. However, this passive method of increasing the opening speed does not significantly improve the opening speed. A new parachute is needed that uses an active method to increase the opening speed.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figures 1 to 4 In an embodiment of the present invention, a fast-opening parachute 100 includes a main parachute body 10 and a parachute bag. The parachute bag is used to accommodate the main parachute body 10. When the parachute is opened, the main parachute body 10 is pulled out of the parachute bag by guiding the parachute.

[0030] As a preferred embodiment, an inflatable airbag passage 11 is provided at the outer edge of the main parachute body 10. Specifically, the airbag passage 11 is annular and surrounds the outer periphery of the main parachute body 10. The airbag passage 11 is formed by sewing umbrella cloth. Specifically, the outer edge of the umbrella portion is folded to form two pieces of umbrella cloth, and the airbag passage 11 is formed by sewing the umbrella cloth. As an optional embodiment, two independent umbrella cloths can be sewn into the airbag passage 11 and then sewn to the outer periphery of the main parachute body 10. As another optional embodiment, an independent umbrella portion can be directly sewn to the main parachute body 10 to form the airbag passage.

[0031] As a specific embodiment, a fast-opening parachute 100 also includes: an air storage device 20. The air storage device 20 stores compressed gas. As a specific embodiment, the compressed gas is air. As an optional embodiment, the compressed gas can also be helium. The air storage device 20 is fixed to the main parachute body 10. When the main parachute body 10 is separated from the parachute bag, the air storage device 20 releases gas to the airbag channel 11 so that the outer edge of the main parachute body 10 is opened. For a circular main parachute body 10, when the air storage device 20 releases gas to the airbag channel 11, the main parachute body 10 can be quickly unfolded.

[0032] As a specific embodiment, the gas storage device 20 includes: an inner tube 21 for accommodating compressed gas, an inflation pipeline 22 for inflating the inner tube 21, an outer tube 23, a lock pin 24 and an unlocking pull rope. The inner tube 21 is controlled to release compressed gas outward by the relative position of the outer tube 23 and the inner tube 21. The outer tube 23 is slidably sleeved on the outer periphery of the inner tube 21. The inner tube 21 is formed with an outlet hole 211 for inflating the airbag channel 11. The outer tube 23 has a deflation position and a locking position relative to the inner tube 21. In the locking position, the outer tube 23 closes the outlet hole 211. In the deflation position, the outlet hole 211 is open. The inflation pipeline 22 is connected to the inner tube 21 and a one-way valve 221 is provided on the inflation pipeline 22. The lock pin 24 passes through the outer tube 23 and is inserted into the inner tube 21 to lock the inner tube 21 and the outer tube 23. The unlocking pull rope connects the lock pin 24 and the parachute bag. When the parachute is separated from the parachute bag, the unlocking pull rope will be tightened and pull out the lock pin 24. Specifically, when the main parachute body 10 is separated from the parachute bag, the unlocking pull rope drives the lock pin 24 to be pulled out, and the compressed gas in the inner tube 21 pushes the outer tube 23 to slide relative to the inner tube 21, thereby opening the gas outlet 211 to release gas to the airbag channel 11.

[0033] As a preferred embodiment, the gas storage device 20 further includes: a guide rod 25 and a limiter 26. The limiter 26 is used to limit the sliding position of the outer cylinder 23 relative to the inner cylinder 21. The guide rod 25 is used to guide the outer cylinder 23 to slide relative to the inner cylinder 21.

[0034] The front end of the guide rod 25 is fixed to the outer cylinder 23. The inner cylinder 21 is formed with a through hole. The guide rod 25 passes through the through hole. The stopper 26 is fixed to the rear end of the guide rod 25. The through hole is located between the stopper 26 and the outer cylinder 23. The setting of the stopper 26 prevents the outer cylinder 23 from being completely separated from the inner cylinder 21.

[0035] As a preferred embodiment, the guide rod 25 includes: a smooth rod portion and a threaded portion with a threaded structure. The stopper 26 is a nut. The nut and the threaded portion form a threaded connection. The smooth rod portion passes through the through hole.

[0036] As a specific implementation manner, the number of the guide rods 25 and the number of the limiting members 26 are both two.

[0037] As a preferred embodiment, the front end of the inner cylinder 21 is provided with an inner conical structure. The air outlet 211 is arranged on the inner conical structure. The front end of the outer cylinder 23 is provided with an outer conical structure adapted to the inner conical structure. The outer conical structure is sleeved on the outer surface of the inner conical structure. The front end of the outer conical structure is provided with an injection port 231.

[0038] When the outer cylinder 23 is in the locking position, the inner wall surface of the outer cone structure covers the outer wall surface of the inner cone structure, thereby closing the air outlet 211. When the outer cylinder 23 is in the deflation position, the air outlet 211 is connected to the injection port 231. A gap is formed between the outer cone structure and the inner cone structure. The gap connects the air outlet 211 and the injection port 231, so that the compressed air discharged from the air outlet 211 can be discharged to the outside through the injection port 231.

[0039] As a preferred embodiment, the gas storage device 20 further includes: a rubber seal 27. The rubber seal 27 is fixed to the inner wall surface of the outer conical structure. The rubber seal 27 is located between the outer conical structure and the inner conical structure.

[0040] As a preferred embodiment, the front end of the whole formed by the outer tube 23 and the inner tube 21 extends into the airbag passage 11. The inflation pipeline 22 is connected to the rear end of the inner tube 21.

[0041] As a specific embodiment, the outer surface of the outer tube 23 is provided with a plurality of sewing rings 232. The outer tube 23 is fixed to the main parachute 10 by sewing the sewing rings 232 and the main parachute 10. The sewing rings 232 are formed with holes.
