[0019] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] The present invention provides a parachute folding and compressing device, the structure of which is as follows: Figure 1 - Figure 4 As shown, it includes a folding mechanism 1 and a compression mechanism 3.

[0021] The folding mechanism comprises a bracket 11, a placement plate 12 is provided in the middle of the bracket 11, a plurality of side pressure plates 13 are symmetrically slidably connected to the bracket 11, and a first driving assembly 2 for driving the plurality of side pressure plates 13 to slide simultaneously is provided on the bracket 11.

[0022] The compression mechanism 3 includes an upper pressing plate 31 slidably connected to the bracket 11 , and the bracket 11 is provided with a second driving component 4 for driving the upper pressing plate 31 to slide.

[0023] When in use, the parachute is placed flatly on the placement plate 12 in the middle of the bracket 11. The placement plate 12 provides a stable support surface for the parachute, which is convenient for subsequent folding operations. The first drive assembly 2 starts to work, and its function is to simultaneously drive multiple side pressure plates 13 that are symmetrically slidably connected on the bracket 11. Under the action of the first drive assembly 2, multiple side pressure plates 13 slide along the bracket 11 toward the parachute on the placement plate 12. As the side pressure plates 13 approach, they gradually fold the edges of the parachute toward the center. Since the side pressure plates 13 are symmetrically arranged, the parachute can be folded from multiple directions at the same time, making the folding process more neat and efficient. When the parachute is folded, the second drive assembly 4 is started. The second drive assembly 4 drives the upper pressure plate 31 to slide downward along the bracket 11 and move toward the folded parachute on the placement plate 12. The upper pressure plate 31 gradually approaches the parachute, applies pressure to the folded parachute, and compresses it to a smaller volume.

[0024] In the present invention, the parachute can be folded quickly and neatly through the symmetrical arrangement and synchronous movement of multiple side pressure plates 13. Compared with the traditional manual folding method, the folding efficiency is greatly improved, saving time and labor costs. The upper pressure plate 31 of the compression mechanism 3 can apply sufficient pressure to the folded parachute to compress it to a smaller volume. Through the synergistic effect of the folding mechanism 1 and the compression mechanism 3, efficient folding and compression of the parachute is achieved, which provides convenience for the storage, transportation and use of the parachute.

[0025] To drive the side pressure plate 13 to slide, please refer to Figure 2 In a preferred embodiment, the first driving component 2 includes a plurality of screw rods 21 symmetrically rotatably connected to the bracket 11, the plurality of screw rods 21 are respectively threadedly connected to a plurality of side pressure plates 13, and the bracket 11 is provided with a first power component 5 for simultaneously driving the plurality of screw rods 21 to rotate.

[0026] When the parachute needs to be folded, the first drive assembly 2 is started. When the first power assembly 5 is started, it starts to output power. The first power assembly 5 is connected to the multiple screw rods 21 symmetrically connected to the bracket 11, so that the multiple screw rods 21 can rotate synchronously. When the screw rods 21 rotate, due to the effect of the thread, the side pressure plates 13 will slide along the axial direction of the screw rods 21. As the side pressure plates 13 slide, they gradually approach the parachute and exert pressure on the edges of the parachute to fold it toward the center.

[0027] In order to drive multiple screw rods 21 to rotate simultaneously, please refer to Figure 3In a preferred embodiment, the first power assembly 5 includes a driven bevel gear 51 coaxially arranged on the screw rod 21, a motor 52 is arranged on the bracket 11, and an active bevel gear 53 meshing with multiple driven bevel gears 51 is arranged on the output shaft of the motor 52.

[0028] When in use, the motor 52 on the bracket 11 is started, and as the output shaft of the motor 52 rotates, the active bevel gear 53 also starts to rotate. The active bevel gear 53 meshes with the driven bevel gears 51 on multiple screws 21 at the same time. When the active bevel gear 53 rotates, power is transmitted to each driven bevel gear 51 through meshing. The driven bevel gear 51 starts to rotate around the axis of the screw 21. Since the driven bevel gear 51 is coaxially arranged with the screw 21, the rotation of the driven bevel gear 51 drives the screw 21 to rotate together. As the screw 21 rotates, due to the threaded connection relationship, the side pressure plate 13 starts to slide along the axial direction of the screw 21.

[0029] To support the parachute, refer to Figure 2 In a preferred embodiment, a telescopic plate 6 is provided between the placement plate 12 and the side pressure plate 13, and the telescopic plate 6 includes a first plate body 61 provided on the placement plate 12, and a second plate body 62 is provided on the side pressure plate 13, and the first plate body 61 is slidably connected to the second plate body 62.

[0030] During use, when the parachute needs to be folded, the first drive assembly 2 is started, and the side pressure plate 13 begins to slide toward the parachute on the placement plate 12. As the side pressure plate 13 approaches, the second plate body 62 on the side pressure plate 13 slides relative to the first plate body 61 on the placement plate 12. The telescopic plate 6 plays a supporting and guiding role during the sliding process of the side pressure plate 13. On the one hand, it provides a continuous supporting surface for the edge of the parachute, making the parachute more stable during the folding process and less prone to wrinkles or deformation. On the other hand, the sliding direction of the telescopic plate 6 is consistent with the moving direction of the side pressure plate 13, guiding the side pressure plate 13 to accurately fold the parachute. In short, the telescopic plate 6 between the placement plate 12 and the side pressure plate 13 is extended and contracted by relative sliding, plays a supporting, guiding and gap-preventing role during the folding process of the parachute, and improves the stability and adaptability of the folding operation.

[0031] To reduce the possibility of parachute damage, please refer to Figure 1 In a preferred embodiment, an elastic layer 14 is provided on the inner side of the side pressure plate 13 .

[0032] When in use, as the side pressure plate 13 approaches, the elastic layer 14 on the inner side of the side pressure plate 13 first contacts the parachute. The elastic layer 14 is usually made of elastic materials such as rubber and sponge, and can play a buffering role. When the side pressure plate 13 applies pressure to the parachute to fold, the elastic layer 14 can absorb part of the impact force, reduce the instantaneous pressure on the parachute, and prevent the parachute from being damaged due to excessive pressure.

[0033] To enhance the support of the parachute, please refer to Figure 1 In a preferred embodiment, a side pressing cloth 7 is provided between adjacent side pressing plates 13 , and a shrinking component 8 for shrinking the side pressing cloth 7 is provided on adjacent side pressing plates 13 .

[0034] When in use, as the side pressure plates 13 move, the distance between adjacent side pressure plates 13 gradually decreases. The side pressure cloth 7 plays a role in assisting folding in this process. It can cover part of the surface of the parachute to help guide the folding direction of the parachute, and also prevent part of the parachute from accidentally popping out or loosening during the folding process.

[0035] To shrink the side press 7, refer to Figure 4 In a preferred embodiment, the shrinking component 8 includes a roller 81 rotatably connected to the side pressure plate 13, and the two sides of the side pressure cloth 7 are respectively wound around the rollers 81 on the adjacent side pressure plates 13. A torsion spring is sleeved on the roller 81, one end of the torsion spring is connected to the roller 81, and the other end of the torsion spring is connected to the side pressure plate 13. The torsion spring causes the end of the side pressure cloth 7 to have a tendency to move toward the side pressure plate 13.

[0036] When in use, when the side pressure plate 13 gradually approaches the parachute and performs a folding operation on it, the side pressure cloth 7 is in close contact with the parachute, and the side pressure plate 13 is assisted to squeeze and fold the parachute. In this process, the side pressure cloth 7 is subjected to the reaction force of the parachute, so that the torsion spring on the roller 81 is further twisted. The torsion spring continuously accumulates force under the pulling force of the side pressure cloth 7, generating an increasingly large restoring force. One end of the torsion spring is connected to the roller 81, and the other end is connected to the side pressure plate 13, so that the roller 81 always has a tendency to rotate toward the side pressure plate 13. When the side pressure plate 13 completes the folding operation on the parachute, the energy stored in the torsion spring begins to be released. The restoring force of the torsion spring causes the roller 81 to rotate toward the side pressure plate 13, and the side pressure cloth 7 is gradually wound around the roller 81. The two ends of the side pressure cloth 7 move toward the side pressure plate 13 under the rotation of the roller 81, thereby tightening the side pressure cloth 7 and tightly wrapping the folded parachute. The contracted side pressure cloth 7 applies continuous pressure to the folded parachute to prevent the parachute from loosening or deforming in subsequent operations. The effect of the torsion spring makes the side pressure cloth 7 always maintain a certain tension to ensure that the shape of the parachute is stable.

[0037] To drive the upper pressing plate 31 to move, please refer to Figure 1 In a preferred embodiment, the second driving assembly 4 includes a cylinder 41 disposed on the bracket 11 , and a piston rod of the cylinder 41 is connected to the upper pressing plate 31 .

[0038] When in use, under the push of the piston rod of the cylinder 41, the upper pressing plate 31 slides downward along the bracket 11, gradually approaching the folded parachute on the placing plate 12. After the upper pressing plate 31 contacts the parachute, it continues to apply pressure downward to compress the folded parachute.

[0039] To reduce the possibility of parachute damage, please refer to Figure 1 In a preferred embodiment, a buffer plate 32 is provided at the bottom of the upper pressure plate 31, and a spring 33 is provided between the buffer plate 32 and the upper pressure plate 31, one end of the spring 33 is connected to the upper pressure plate 31, and the other end of the spring 33 is connected to the buffer plate 32, and the spring 33 is in its original length state.

[0040] When in use, as the piston rod of the cylinder 41 extends, the upper pressing plate 31 begins to move downward, gradually approaching the folded parachute on the placing plate 12. During the descent of the upper pressing plate 31, the buffer plate 32 at the bottom of the upper pressing plate 31 first contacts the parachute. Since the spring 33 is in the original length state at this time, the pressure of the buffer plate 32 on the parachute is relatively small. As the upper pressing plate 31 continues to move downward, the buffer plate 32 is subjected to the reaction force of the parachute and begins to move toward the upper pressing plate 31. At this time, the spring 33 connected between the buffer plate 32 and the upper pressing plate 31 begins to be compressed. The compression of the spring 33 plays a buffering role. When the cylinder 41 applies a large pressure to the upper pressing plate 31 for compression, the spring 33 can absorb part of the impact force to prevent the upper pressing plate 31 from instantly applying too much pressure to the parachute and damaging the parachute. At the same time, the elasticity of the spring 33 also makes the compression process more stable, reducing the impact and wear on the parachute. The presence of the spring 33 enables the buffer plate 32 to better adapt to the surface shape of the parachute, ensuring that the pressure applied by the upper pressing plate 31 to the parachute is more uniform. Even if there are uneven parts on the surface of the parachute, the spring 33 can adjust the position of the buffer plate 32 through its own compression and extension, so that the pressure is evenly distributed on the parachute, thereby improving the compression effect.

[0041] To improve compression, refer to Figure 1 In a preferred embodiment, both the upper pressing plate 31 and the buffer plate 32 are provided with air holes 34 .

[0042] When in use, as the upper pressing plate 31 moves downward, the parachute is compressed. During the compression process, the air inside the parachute is squeezed and needs to find an outlet to discharge. The air holes 34 on the upper pressing plate 31 and the buffer plate 32 provide a channel for the air to be discharged.

[0043] In order to better understand the present invention, the following Figure 1 - Figure 4 The working principle of the technical solution of a parachute folding and compression device of the present invention is described in detail: the parachute is placed flatly on the placement plate 12 in the middle of the bracket 11. The placement plate 12 provides a stable support surface for the parachute, which is convenient for the subsequent folding operation. The first drive assembly 2 starts to work, and its function is to simultaneously drive the multiple side pressure plates 13 symmetrically connected to the bracket 11. Under the action of the first drive assembly 2, the multiple side pressure plates 13 slide along the bracket 11 toward the parachute on the placement plate 12. As the side pressure plates 13 approach, they gradually fold the edges of the parachute toward the center. Since the side pressure plates 13 are symmetrically arranged, the parachute can be folded from multiple directions at the same time, making the folding process more neat and efficient. When the parachute is folded, the second drive assembly 4 is started. The second drive assembly 4 drives the upper pressure plate 31 to slide downward along the bracket 11 and move toward the folded parachute on the placement plate 12. The upper pressure plate 31 gradually approaches the parachute, applies pressure to the folded parachute, and compresses it to a smaller volume.

[0044] The specific implementation of the present invention described above does not constitute a limitation on the protection scope of the present invention.
