Abstract
Description
Technical Field
[0001] This application relates to the field of aviation technology, and in particular to parachute containment devices and systems. Background Technology
[0002] A parachute container, commonly known as a parachute pack, is a device used to store and deploy parachutes. It is designed to allow a parachutist to easily retrieve the parachute from the container when jumping from an aircraft or other spacecraft, and to ensure that the parachute can open correctly.
[0003] Parachute containers in this technology typically use a simple cap that snaps into the container opening, or the cap is sealed to the opening with glue. However, the snap-fit method results in poor sealing of the parachute container, and the sealed method makes the cap difficult to open, affecting parachute ejection. Utility Model Content
[0004] To address or partially address the problems existing in related technologies, this application provides a parachute containment device and system that not only enables the sealed assembly of the parachute but also does not affect the parachute's ejection.
[0005] The first aspect of this application provides a parachute containment device, comprising:
[0006] The container body includes a cavity and an opening communicating with the cavity, the opening being used to insert a parachute;
[0007] A sealing assembly includes a heat-shrinkable film for welding to the edge of the opening to seal the opening;
[0008] A one-way exhaust component is installed on the container body, and the exhaust direction of the one-way exhaust component is from the cavity to the outside of the cavity; the one-way exhaust component is used to cooperate with the exhaust device to extract the gas in the cavity, so that the parachute is compressed in the cavity.
[0009] In one implementation, the one-way exhaust component is provided with an exhaust port, which is detachably connected to one end of the suction pipe, and the other end of the suction pipe is connected to a suction device, which is used to extract gas from the cavity through the suction pipe.
[0010] In one implementation, an interface seal is further included, which is detachably installed on the exhaust port of the one-way exhaust component to seal the exhaust port.
[0011] In one implementation, the container and the opening have a set shape, and the shape of the heat-shrink film and / or the cover matches the shape of the opening.
[0012] In one implementation, the sealing assembly further includes a cover for closing the sealed opening.
[0013] In one implementation, the diameter of the cover is smaller than the inner diameter of the opening, the cover is pressed into the opening, and the edge of the cover abuts against the inner wall of the opening.
[0014] In one implementation, the container body is a hollow cylinder, and the opening is an open opening;
[0015] The opening is located at the top of the hollow cylinder, the heat-shrinkable film covers the opening, and the edge of the heat-shrinkable film is fused to the outer wall of the opening.
[0016] In one implementation, the one-way exhaust component is located near the bottom of the container body.
[0017] In one implementation, a gas generating device is provided at the bottom of the container. The gas generated by the gas generating device is used to propel the parachute so that the parachute breaks through the heat-shrink film and is ejected from the container body.
[0018] A second aspect of this application provides a parachute containment system, comprising:
[0019] The parachute containment device as described in the first aspect above; and
[0020] An air extraction device is provided, which is connected to the one-way exhaust component of the parachute containment device via an air extraction pipe.

[0022] The parachute housing device provided in this application has a heat-shrinkable film fused to the edge of the opening, which can seal the opening. An air pump can be used to expel the air from the container body, causing the heat-shrinkable film to shrink and compress the parachute, thereby achieving a sealed assembly of the parachute.
[0023] Furthermore, the sealing assembly also includes a cover body for sealing the opening. The diameter of the cover body is smaller than the inner diameter of the opening, and the cover body is pressed into the opening with its edge abutting against the inner wall of the opening. Based on the sealing assembly achieved through heat-shrink film, the cover body provides structural strength and protection for the heat-shrink film. The cover body and opening are fitted together by a press-fit method, making it easier to open under high pressure without affecting the parachute's ejection.

[0033] Parachute containers in related technologies typically use a simple cap that snaps into the container opening, or a cap that is sealed to the container opening with glue. However, snapping methods result in poor sealing of the parachute container, and sealing methods make the cap difficult to open, affecting parachute ejection. To address the above problems, embodiments of this application provide a parachute housing device and system that not only achieves sealed assembly of the parachute but also does not affect parachute ejection.
[0034] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.
[0035] Figure 1 This is a schematic diagram of the structure of the parachute containment device shown in the embodiments of this application.
[0036] See Figure 1 This application provides a parachute containment device, including a container body 104, a sealing assembly, and a one-way venting component 105. The container body 104 includes a cavity and an opening 114 communicating with the cavity, the opening 114 being used to insert a parachute 103. The sealing assembly includes a heat-shrinkable film 102, which is welded to the edge of the opening 114 to seal the opening 114. The one-way venting component 105 is installed on the container body 104, for example, the venting assembly is connected near the bottom of the container body 104. The venting direction of the one-way venting component 105 is from the cavity to the outside of the cavity; the one-way venting component 105 is used to cooperate with a venting device to extract gas from the cavity, compressing the parachute 103 within the cavity.
[0037] The parachute housing device provided in this application has a heat-shrinkable film 102 fused to the edge of the opening 114, which can seal the opening 114. The air inside the container body 104 can be discharged by an air pump, so that the heat-shrinkable film 102 shrinks and presses the parachute 103 inside the container body 104, thereby achieving the sealed assembly of the parachute 103.
[0038] Compared with related technologies, the parachute containment device of this application has better sealing performance, which can ensure that the parachute 103 inside is not damp, thereby extending the service life of the parachute 103. In addition, the degree of compression of the parachute 103 can be controlled, thereby improving the success rate of parachute opening.
[0039] In some embodiments, the one-way exhaust component 105 has an exhaust port on the part outside the container body 104. The exhaust port is used to detachably connect to one end of the suction pipe 107. The other end of the suction pipe 107 is connected to the suction device 108, which is used to extract gas from the cavity through the suction pipe 107.
[0040] In this embodiment, the one-way exhaust component 105 is fixedly installed on the container body 104. The one-way exhaust component 105 can be a one-way exhaust valve or a structural component with one-way exhaust function, such as a valve core.
[0041] During evacuation, one end of the evacuation pipe 107 can be connected to the exhaust port to remove gas from the cavity. Simultaneously, due to the negative pressure within the cavity, the heat-shrink film 102 contracts inwards towards the opening 114, thus compressing the parachute 103. Once the parachute 103 is compressed to a suitable degree, the evacuation device 108 can be shut off. Because this application can compress the parachute 103 according to a set air pressure, and the degree of compression is controllable, it ensures that the internal parachute 103 remains dry, thereby improving the success rate of parachute deployment.
[0042] In this embodiment, the heat shrink film 102 is fused to the side wall of the opening 114 of the container body 104 by an external heating device when assembling the parachute 103, and then the heat shrink film 102 is shaped and sealed by a hot air gun.
[0043] Heat shrink film 102, also known as heat shrink film or shrink film, is a polymer film that can be shrunk by heat. Its main principle is that after heating, the molecular structure of the film changes, causing its volume to shrink, thus tightly wrapping the object. Heat shrink film 102 has good transparency, toughness, and tear resistance. The material of heat shrink film 102 in this embodiment may include one of PVC, PE, PP, PET, OPP, PVDC, and POF.
[0044] See also Figure 1In some embodiments, an interface seal 106 is also included, which is detachably mounted on the exhaust port of the one-way exhaust component 105 to seal the exhaust port. The interface seal 106 may be a sealing nut that is threadedly connected to the exhaust port.
[0045] When venting, unscrew the sealing nut from the venting port of the one-way venting component 105, insert the suction pipe 107, and start the suction pump to vent the air, so that the air inside the container body 104 is discharged.
[0046] In this embodiment, the container and the opening 114 have a set shape. The shape of the heat shrink film 102 and / or the cover 101 matches the shape of the opening 114. For example, when the container is cylindrical, the opening 114 is circular. Therefore, the heat shrink film 102 can be set to be circular.
[0047] See also Figure 1 In some embodiments, the sealing assembly further includes a cover 101, which may be made of rubber or carbon fiber. The cover 101 is used to cover the sealed opening 114, wherein the diameter of the cover 101 is smaller than the inner diameter of the opening 114, the cover 101 is pressed into the opening 114, and the edge of the cover 101 abuts against the inner wall of the opening 114. That is, it is fixed by compression, utilizing the friction between the side of the cover 101 and the inner wall of the container.
[0048] After the air extraction is complete, cover the opening 114 with the cover 101, that is, cover the outside of the heat shrink film 102, and tighten the sealing nut back to the exhaust port.
[0049] Based on the sealing assembly of the parachute through the heat shrink film 102, the cover 101 can improve the structural strength and also protect the heat shrink film 102. The cover 101 and the opening 114 are connected by a press-fit method, which makes it easier to open under high pressure and will not affect the ejection of the parachute 103.
[0050] In some embodiments, the diameter of the cover 101 may also be larger than the inner diameter of the opening 114, and the cover 101 is fastened to the opening 114.
[0051] In some embodiments, the container body 104 is a hollow cylindrical body, such as a tube, with an open opening 114 located at the top of the hollow cylindrical body. A heat-shrinkable film 102 covers the opening 114, and the edge of the heat-shrinkable film 102 is fused to the outer wall of the opening 114.
[0052] This application also provides a parachute containment system, including a parachute containment device as described in the above embodiment and an air extraction device 108, wherein the air extraction device 108 is connected to the one-way exhaust component 105 of the parachute containment device via an air extraction pipe 107.
[0053] The parachute containment system provided in this application enables rapid and standardized assembly of the parachute 103. Through the air extraction device 108, a specific pressure can be set to achieve uniform and standardized filling of the parachute 103. At the same time, it ensures that the parachute 103 inside the cavity is not damp, thus extending the life of the parachute 103. Furthermore, the degree of compression of the parachute 103 can be controlled through the air extraction device 108, that is, the parachute 103 can be compressed according to the set air pressure. Since the degree of compression is controllable, the success rate of parachute opening can be improved.
[0054] The embodiments of the present application have been described above. The above description is illustrative and not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is selected to best explain the principles of the embodiments, their practical applications, or improvements to the technology in the market, or to enable other persons skilled in the art to understand the embodiments disclosed herein.
