Description

Technical Field

[0001] This invention relates to the field of parachute technology, and more particularly to a centrally penetrating parachute compartment and parachute system. Background Technology

[0002] A parachute typically consists of components such as the parachute itself, the parachute pack, and the parachute compartment. Once the parachute is packed into the parachute pack and then into the parachute compartment, it becomes an independent, fully enclosed structure.

[0003] In conventional applications, the parachute system is usually located at the end of the load (i.e., the load is located at the front of the parachute system). For example, patent application number 201620864606.4 discloses a drone parachute compartment and a drone. The drone parachute compartment includes a cylindrical body; an upper cover disposed on the bottom of the cylindrical body; and a support plate disposed inside the cylindrical body. The upper cover and the support plate are used to house the parachute.

[0004] With technological advancements, some applications now include components (such as engines) at the rear end of the parachute system. In these applications, the connection between components located at the front and rear ends of the parachute system can only utilize the peripheral circumferential space of the parachute system, and cannot utilize the central part of the parachute system. This makes it impossible to guarantee a reliable connection for fragile components such as cables, as they are located in the peripheral space and exposed to high-speed airflow. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose a centrally penetrating parachute compartment and parachute system. This solves the technical problem that in the prior art, the connection between the front and rear components of the parachute system can only use the peripheral circumferential space of the parachute system and cannot utilize the central part of the parachute system. As a result, for fragile components such as cables, reliable connection cannot be guaranteed because they are located in the peripheral space and exposed to high-speed airflow.

[0006] To achieve the above-mentioned technical objectives, the present invention provides a centrally penetrating parachute canopy, comprising a canopy body, a canopy cover, and a guide sleeve. The canopy cover is detachably disposed on the top of the canopy body. Through holes are provided at corresponding positions on the bottom of the canopy body and the canopy cover. The guide sleeve is fixedly disposed inside the canopy body, and both ends of the guide sleeve are respectively connected to the through holes located at the bottom of the canopy body and on the canopy cover.

[0007] Furthermore, the centrally penetrating umbrella compartment also includes several connecting umbrella panels, which are fixedly installed on the upper surface of the bottom of the umbrella compartment body.

[0008] Furthermore, the number of connecting umbrella panels is set to multiple, and the multiple connecting umbrella panels are distributed circumferentially at the bottom of the umbrella compartment.

[0009] The technical solution of the present invention also provides a parachute system, which includes a centrally penetrating parachute compartment and a parachute. The parachute includes a canopy and multiple parachute lines that are fixedly connected. The canopy and the parachute lines are both housed in the parachute compartment, and the distal ends of the parachute lines are fixedly connected to the bottom of the parachute compartment body.

[0010] Furthermore, the umbrella canopy has a top hole at its center, which is movably fitted onto the outer surface of the guide sleeve.

[0011] Furthermore, the parachute system also includes a parachute pack, which is disposed inside the parachute compartment and fixedly connected to the canopy. The canopy and the parachute lines are both housed inside the parachute pack, and the canopy is fixedly connected to the parachute pack. The distal ends of the parachute lines pass through the parachute pack and are fixedly connected to the bottom of the parachute compartment body.

[0012] Furthermore, the umbrella pack includes an umbrella pack body and a sleeve. The sleeve is fixedly mounted on the umbrella pack body and penetrates the umbrella pack body. The umbrella top hole is movably fitted onto the outer surface of the sleeve, and the sleeve is movably fitted onto the outer surface of the guide sleeve.

[0013] Furthermore, the parachute system also includes several tethering ropes, and the canopy is fixedly connected to the parachute pack via the tethering ropes.

[0014] Furthermore, at least two tethering ropes are provided, and multiple tethering ropes are evenly distributed along the circumference of the umbrella top hole.

[0015] Furthermore, the distal ends of the parachute lines are gathered into multiple bundles and evenly distributed on the outside of the guide sleeve and fixedly connected to the bottom of the parachute compartment body.

[0016] Compared with the prior art, the beneficial effects of the present invention include:

[0017] (1) By providing through holes at corresponding positions on the bottom of the parachute body and the canopy, and connecting the two ends of the guide sleeve to the through holes located on the bottom of the parachute body and the canopy respectively, when it is necessary to connect the front and rear components of the parachute system through the intermediate connector, the intermediate connector can pass through the inside of the guide sleeve and connect to the front and rear components of the parachute system respectively. This overcomes the limitation that the current connection of the front and rear components of the parachute system can only use the peripheral circumferential space of the parachute system, thereby avoiding the inability to guarantee a reliable connection due to the intermediate connector being in the peripheral space and exposed to high-speed airflow.

[0018] (2) The guide sleeve can separate the internal space of the parachute compartment from the connector to avoid the connector from getting tangled or interfering with the parachute located inside the parachute compartment. Attached Figure Description

[0020] Figure 2 This embodiment presents a schematic diagram of the internal structure of the parachute compartment body;

[0021] Figure 3 This is a schematic diagram of the structure of a parachute system provided by the present invention. Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0023] This invention provides a centrally penetrating parachute compartment, the structure of which is as follows: Figure 1 As shown, the parachute includes a canopy body 11, a canopy cover 12, and a guide sleeve 13. The canopy cover 12 is detachably mounted on the top of the parachute body 11. Through holes are provided at corresponding positions on the bottom of the parachute body 11 and the canopy cover 12. The guide sleeve 13 is fixedly mounted inside the parachute body 11, and both ends of the guide sleeve 13 are connected to the through holes located at the bottom of the parachute body 11 and on the canopy cover 12, respectively.

[0024] In the centrally penetrating parachute compartment, through holes are provided at corresponding positions on the bottom of the parachute compartment body 11 and the canopy 12, and the two ends of the guide sleeve 13 are respectively connected to the through holes located on the bottom of the parachute compartment body 11 and the canopy 12. When it is necessary to connect the front and rear components of the parachute system through the intermediate connector, the intermediate connector can pass through the inside of the guide sleeve 13 and connect to the front and rear components of the parachute system respectively. This overcomes the current limitation that only the peripheral circumferential space of the parachute system can be used to connect the front and rear components of the parachute system. This avoids the intermediate connector being exposed to high-speed airflow in the peripheral space, which could lead to unreliable connection. In addition, the guide sleeve 13 can separate the internal space of the parachute compartment 1 from the connector to prevent the connector from getting entangled or interfering with the parachute inside the parachute compartment 1.

[0025] like Figure 2The diagram shown is a schematic diagram of the internal structure of the parachute compartment body 11 in this embodiment. In order to facilitate connection with the parachute, as a preferred embodiment, the parachute compartment also includes several connecting parachute plates 14, which are fixedly disposed on the upper surface of the bottom of the parachute compartment body 11.

[0026] In a specific embodiment, the number of connecting umbrella panels 14 is set to multiple, and the multiple connecting umbrella panels 14 are distributed circumferentially at the bottom of the umbrella compartment 1.

[0027] The present invention also provides a parachute system, the structure of which is as follows: Figure 3 As shown, the parachute includes a centrally penetrating parachute compartment 1 and a parachute 2. The parachute 2 includes a fixedly connected canopy 21 and multiple parachute lines 22. The canopy 21 and the parachute lines 22 are both housed in the parachute compartment 1, and the distal ends of the parachute lines 22 are fixedly connected to the bottom of the parachute compartment body 11.

[0028] In this embodiment, since the through hole is located at the center of the bottom of the umbrella compartment body 11 and the center of the canopy 12, in a preferred embodiment, the distal ends of the parachute ropes 22 are gathered into multiple rope bundles and evenly distributed on the outside of the guide sleeve 13 and fixedly connected to the bottom of the umbrella compartment body 11.

[0029] In a preferred embodiment, the umbrella canopy 21 has a top hole 210 at its center, and the top hole 210 is movably fitted onto the outer surface of the guide sleeve 13.

[0030] It is understandable that by movably fitting the umbrella top hole 210 of the umbrella canopy 21 onto the outer surface of the guide sleeve 13, when the umbrella canopy 21 is pulled up and unfolded, the circumferential direction of the umbrella canopy 21 can be evenly stressed, so that the umbrella canopy 21 can open smoothly, thereby improving the success rate of the umbrella canopy 21 opening.

[0031] Please continue to refer to Figure 3 Furthermore, the parachute system also includes a parachute pack 3, which is disposed inside the parachute compartment 1 and fixedly connected to the canopy 12. The parachute canopy 21 and the parachute lines 22 are both housed inside the parachute pack 3, and the parachute canopy 21 is fixedly connected to the parachute pack 3. The distal end of the parachute lines 22 passes through the parachute pack 3 and is fixedly connected to the bottom of the parachute compartment body 11.

[0032] In order to enable the umbrella pack 3 to be smoothly pulled out from the umbrella compartment 1, in a preferred embodiment, the umbrella pack 3 includes an umbrella pack body 31 and a sleeve 32. The sleeve 32 is fixedly disposed on the umbrella pack body 31 and penetrates the umbrella pack body 31. The umbrella top hole 210 is movably sleeved on the outer surface of the sleeve 32, and the sleeve 32 is movably sleeved on the outer surface of the guide sleeve 13.

[0033] It is understood that by configuring the parachute pack 3 to include the parachute pack body 31 and the sleeve 32, the cooperation between the sleeve 32 and the guide sleeve 13 can ensure that the parachute pack 3 can be smoothly pulled out of the parachute compartment 1.

[0034] To achieve the connection between the parachute pack 3 and the parachute 2, in a preferred embodiment, the parachute system further includes several top ropes 4, and the canopy 21 is fixedly connected to the parachute pack 3 via the top ropes 4. In a specific embodiment, at least two top ropes 4 are provided, and the multiple top ropes 4 are evenly distributed circumferentially along the top hole 210 of the parachute.

[0035] To facilitate understanding of the present invention, the following is combined with... Figures 1-3 The working principle of this solution will be explained in detail below:

[0036] During assembly of the parachute system, the parachute 2 is first installed into the parachute pack 3. Specifically, the top hole 210 is first movably fitted onto the outer surface of the sleeve 32, then the canopy 21 is placed into the parachute pack 3, and the canopy 21 is fixedly connected to the parachute pack 3 via the top rope 4. The parachute rope 22 is passed through the parachute pack 3 and fixedly connected to the connecting plate 14 at the bottom of the parachute compartment body 11. Then, the sleeve 32 is movably fitted onto the outer surface of the guide sleeve 13, and the parachute pack body 31 is placed into the parachute compartment body 11. After the canopy 12 is fixedly connected to the parachute pack 3, the canopy 12 is detachably fixed to the top of the parachute compartment body 11.

[0037] During operation, after the entire payload-parachute system is deployed in the air, the components located at the rear end of the parachute (such as the engine) are jettisoned first. Then, the canopy 12 disengages from the parachute compartment body 11. The canopy 12 flies out and pulls the parachute pack 3 out of the parachute compartment body 11. During this process, the tether rope 4 is gradually straightened. When it is pulled to a certain distance, the parachute pack 3 opens, and the canopy 21 is pulled out. The tether rope 4 continues to be straightened and tightened. When the tether rope 4 breaks, the canopy 12 and the parachute pack 3 separate from the canopy 21. The canopy 21 inflates and begins to decelerate the payload.

[0038] The specific embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. Any other corresponding changes and modifications made in accordance with the technical concept of the present invention should be included within the scope of protection of the claims of the present invention.
