Description

Technical Field

[0001] The utility model relates to the technical field of parachute-free airdrop packaging, in particular to a parachute-free airdrop packaging structure. Background Art

[0002] Parachuteless airdrop, that is, airdrop without parachute, overcomes the disadvantages of road and rail transportation that cannot reach quickly and directly, and solves the problem of low efficiency of parachute airdrop. It has many advantages such as short preparation time, simple operation, small dispersion range, and fast collection. In the field of parachuteless airdrop, parachuteless airdrop packaging boxes and suspended fastening packaging boxes are usually used to contain the items to be dropped.

[0003] However, in order to cope with the huge impact force and vibration generated during the airdrop process, traditional parachute-free airdrop packaging boxes have high requirements on their thickness and structure. This often leads to the need to use a large amount of internal cushioning materials to ensure the safety of the contents. However, these cushioning materials increase the "passive weight" of the parachute-free airdrop packaging boxes, that is, the weight that does not directly contribute to the transportation or delivery performance, thereby increasing the overall weight and volume.

[0004] For equipment such as small drones, their load-bearing and grabbing capabilities are limited, and too much "passive weight" will significantly affect the flight performance and delivery capabilities of the drone, increase energy consumption and reduce delivery efficiency. At the same time, traditional parachute-free airdrop packaging boxes usually adopt a square shape design, which usually makes them "hard landing" when landing, increasing the impact force during landing and limiting their use in different terrain conditions.

[0005] The suspended and fastened packaging box uses a relatively hard corrugated cardboard or honeycomb cardboard as the outer packaging box, and two layers of plastic film with good elasticity inside clamp the goods from both sides, so that the goods are suspended and fixed in the outer packaging box, meeting the requirements of cushioning packaging. Suspended and fastened packaging boxes are usually used to protect small commodities in general storage and transportation environments. Although this type of packaging box can protect the goods from vibration and impact to a certain extent through its suspended and fastened structure, its original design is not suitable for the extreme environment of parachute-free airdrops. The strength and structure of the suspended and fastened packaging box are difficult to withstand the huge impact force generated during the airdrop process.

[0006] In summary, the existing parachute-free airdrop packaging boxes and suspended fastened packaging boxes have certain limitations in design, function and use; therefore, a new parachute-free airdrop packaging structure is urgently needed to solve at least one of the above problems.

[0035] The utility model provides a parachute-free airdrop packaging structure. By improving the parachute-free airdrop packaging structure, the passive weight of the parachute-free airdrop packaging structure is significantly reduced, and the impact resistance of the structure can also be improved.

[0036] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0037] Please refer to Figures 1 to 6 , Figure 1 It is a schematic diagram of a parachute-free airdrop packaging structure in an embodiment of the utility model; Figure 2 yes Figure 1 A partial structural diagram of Figure 3 is a schematic diagram of a circular main ring 101 in an embodiment of the utility model; Figure 4 is a schematic diagram of a semicircular auxiliary ring 102 in an embodiment of the utility model; Figure 5 is a structural schematic diagram of the accommodation portion; Figure 6 FIG. 2 is a schematic structural diagram of a container 200 .

[0038] As shown in the figure, the parachute-free airdrop packaging structure of the utility model is used in the field of parachute-free airdrop technology. The parachute-free airdrop packaging structure specifically includes a container and a bracket 100. The container is used to contain articles. The bracket 100 forms a spherical frame structure and encloses to form an inner cavity. The container is arranged in the inner cavity and is directly or indirectly connected to the bracket 100. That is, the bracket 100 forms a hollow spherical frame structure, and the spherical frame structure has an inner cavity. The bracket 100 defines the outer contour of the parachute-free airdrop packaging structure in the present application, and supports and wraps the container. During the packaging process, the items to be airdropped are placed in the receiving portion, and then the receiving portion is directly or indirectly connected to the bracket 100; in this way, the items to be dropped do not directly contact the bracket 100, but are suspended in the cavity surrounded by the bracket 100 through the receiving portion; the bracket 100 with a spherical structure is connected to the receiving portion, so that the direct collision between the items in the receiving portion and the bracket 100 is avoided, and the buffering and anti-collision function can be better achieved when throwing at low altitude; that is, by adopting the bracket 100 with a spherical structure, the impact force when the parachute-free airdrop packaging structure contacts the ground after being thrown can be reduced, because when the spherical structure bracket 100 hits the ground, if it is subjected to a large impact force, it can release the impact force when contacting the ground by rolling; in addition, when the parachute-free airdrop packaging structure in the present application is dropped to a place with a certain slope, it can use the slope to roll down by itself, thereby improving the applicable environment of drone airdrop, so that the drone can use the slope to achieve throwing; at the same time, this method can also significantly reduce the negative weight of the parachute-free airdrop packaging structure.

[0039] The specific structure of the accommodating part in the present application is described below by way of example. The accommodating part includes two interlocking accommodating parts 200. Each accommodating part 200 includes an annular support ring 201 and an elastic cover 202. The support ring 201 is used to connect with the bracket 100. The inner ring side of the support ring 201 defines a circular space. The outer periphery of the elastic cover 202 is fixedly connected to the support ring 201 and covers the circular space on the inner ring side of the support ring 201. In normal use, the two support rings 201 overlap, and the elastic cover 202 fixed to the two support rings 201 forms a accommodating cavity, which is used to accommodate items. Since the elastic cover 202 is elastic, it can form a tight bundle for the items, that is, wrap the items. At the same time, since the elastic cover 202 is elastic, it can also form a conformal cover with the outer contour of the items, thereby preventing the items from moving in the accommodating cavity, and can also play a supporting effect on the items. At the same time, the edge of the elastic cover 202 is fixedly connected to the support ring 201, and the support ring 201 is connected to the bracket 100. When the bracket 100 is subjected to impact force, even if the impact force is transmitted to the elastic cover 202, the elastic cover 202 can release the impact force through a certain elastic deformation under the action of its elastic force, further preventing the object from being impacted. Among them, the elastic cover 202 has strong toughness and elasticity. The elastic cover 202 can be a plastic film, a membrane structure made of rubber or composite materials, or a mesh structure with similar properties; the support ring 201 has strong impact resistance and pressure resistance, such as hard plastic or metal. The method of providing the support ring 201 to support the elastic cover 202 increases the structural strength of the receiving part on the one hand, and facilitates the packaging of the article on the other hand; the method of connecting the support ring 201 to the bracket 100 can also facilitate the connection between the receiving part and the bracket 100; optionally, in this embodiment, the receiving part is formed into a packaging module, so as to facilitate replacement of damage or convenient use.

[0040] Of course, in addition to the structure of the accommodating part in this embodiment, the accommodating part can also be other structures. For example, the accommodating part itself is two pieces of elastic plastic films, and the elastic plastic films are directly fixedly connected to the bracket 100; or the accommodating part can be connected to the bracket 100 through an elastic part, and the accommodating part itself is a box structure.

[0041] The specific structure of the bracket 100 in the present application is exemplarily described below. In the technical solution of the present application, the bracket 100 includes a first circular ring structure and a second circular ring structure that are cross-connected; the plane where the first circular ring structure is located is perpendicular to the plane where the second circular ring structure is located. Thus, a spherical frame structure can be formed by two connected and perpendicular circular ring structures, so that the bracket 100 can have the function of mitigating impact force. It can be understood that the radial dimensions of each part of the first circular ring structure and the second circular ring structure can be different; that is, the first circular ring structure and the second circular ring structure can be strip-shaped or petal-shaped; when it is petal-shaped, the outer contour of the spherical frame structure can be better displayed, so that the accommodating part can be better protected.

[0042] Optionally, when the receiving portion is connected to the bracket 100, the connecting line formed by the connecting portion of the first circular ring structure and the second circular ring structure is perpendicular to the plane where the support ring 201 is located, and passes through the center of the support ring 201. Thus, the object can be supported by the receiving portion at the center of the sphere, thereby achieving a better buffering effect on the object.

[0043] Optionally, the outer ring side of the first annular structure and the outer ring side of the second annular structure are located on the same spherical surface; that is, the position where the first annular structure and the second annular structure meet is smoothly transitioned without convex points. In this way, stress concentration can be avoided at the position where the first annular structure and the second annular structure meet.

[0044] In a specific example, the first circular ring structure includes a circular main ring 101; the second circular ring structure includes two semicircular auxiliary rings 102, and the two ends of the two semicircular auxiliary rings 102 are connected to the circular main ring 101 to form a closed ring. The first circular ring structure and the second circular ring structure can be easily connected by connecting the two semicircular auxiliary rings 102 to a circular main ring 101 to form a complete closed ring.

[0045] In the technical solution of the present application, the first circular ring structure and the second circular ring structure are detachably connected. For example, the circular main ring 101 includes radially opposite connecting structures 106, and each connecting structure 106 includes two inner ring connecting grooves 1061 and outer ring connecting grooves 1062 spaced apart from each other. The inner ring connecting groove 1061 and the outer ring connecting groove 1062 are located on the same side and are radially opposite to each other; the inner ring connecting groove 1061 is formed by an outward concave surface of the inner ring of the circular main ring 101, and the outer ring connecting groove 1062 is formed by an inward concave surface of the outer ring of the circular main ring 101; there is a spacing section 1063 between the inner ring connecting groove 1061 and the outer ring connecting groove 1062, the outer side of the spacing section 1063 serves as the groove bottom of the outer ring connecting groove 1062, and the inner side of the spacing section 1063 serves as the groove bottom of the inner ring connecting groove 1061, that is, the spacing section 1063 is located between the inner ring connecting groove 1061 and the outer ring connecting groove 1062. Each semicircular auxiliary ring 102 is provided with an inner ring connecting plate 1021 at one end and an outer ring connecting plate 1022 at the other end; the inner ring connecting plate 1021 is extended by a certain distance along the circumferential direction from the inner ring wall of the semicircular auxiliary ring 102; the outer ring connecting plate 1022 is extended by a certain distance along the circumferential direction from the outer ring wall of the semicircular auxiliary ring 102; the inner surface of the inner ring connecting plate 1021 and the inner surface of the semicircular auxiliary ring 102 are located on the same circumferential surface; the outer surface of the outer ring connecting plate 1022 and the outer surface of the semicircular auxiliary ring 102 are located on the same circumferential surface; thereby, it is possible to avoid the formation of convex points at the positions where the first circular ring structure and the second circular ring structure are connected, and to avoid stress concentration. The inner ring connecting plate 1021 can be inserted into the inner ring connecting groove 1061 and connected to the inner ring connecting groove 1061; the outer ring connecting plate 1022 can be inserted into the outer ring connecting groove 1062 and connected to the outer ring connecting groove 1062. In this way, the first circular ring structure can be connected to the second circular ring structure; taking the one side connection structure 106 as an example, the inner ring connecting plate 1021 of one semicircular auxiliary ring 102 is inserted into the inner ring connecting groove 1061, and the outer ring connecting plate 1022 of the other semicircular auxiliary ring 102 is inserted into the outer ring connecting groove 1062, and the fastener 105 is used to penetrate the outer ring connecting plate 1022, the spacer section 1063 and the inner ring connecting plate 1021 in sequence, and the outer ring connecting plate 1022, the spacer section 1063 and the inner ring connecting plate 1021 are fixedly connected using nuts and bolts.

[0046] In the above embodiment, the inner ring sides of the circular main ring 101 and the semicircular auxiliary ring 102 are both provided with limiting grooves 103, which are used to accommodate the support ring 201 and are connected to the support ring 201 through fasteners 105; thus, in the process of connecting the support ring 201 to the bracket 100, the limiting grooves 103 play a positioning role, which facilitates the connection of the accommodating part with the bracket 100. Optionally, the limiting grooves 103 located in the circular main ring 101 are located at the midpoint of the two connecting structures 106; the limiting grooves 103 located in the semicircular auxiliary ring 102 are located at the midpoint of the semicircular auxiliary ring 102. In this way, the force at the position where the first circular ring structure and the second circular ring structure are connected can be made more uniform.

[0047] Optionally, the inner wall of each limiting groove 103 is provided with a buffer 104, and the buffer 104 is made of rubber material. When the support ring 201 is inserted into the limiting groove 103, the buffer 104 is squeezed between the groove wall of the limiting groove 103 and the outer wall of the support ring 201. By providing the rubber material, the impact between the support ring 201 and the limiting groove 103 can be reduced.

[0048] The packaging method of the parachute-free airdrop packaging structure in the present application is described below. During the packaging process, the materials are first placed between the two containers 200. After the two support rings 201 are stacked up and down, pressure is applied to make the elastic cover 202 wrap the items. At this time, the two stacked support rings 201 form an approximately cylindrical structure, and the items can be suspended in the center of the support ring 201 through the elastic cover 202.

[0049] Insert the accommodating portion into the limiting groove 103, and use bolts to form a fixed connection between the support ring 201 and the limiting groove 103; here, the two overlapping support rings 201 can be first connected by the fastener 105, and then the support ring 201 is bolted to the limiting groove 103 of the circular main ring 101; or the two overlapping support rings 201 are not connected to each other, but both support rings 201 are connected to the limiting groove 103.

[0050] Then align the limiting grooves 103 set on the two semicircular auxiliary rings 102 with the support ring 201, insert the inner ring connecting plates 1021 and the outer ring connecting plates 1022 of the two semicircular auxiliary rings 102 into the inner ring connecting grooves 1061 and the outer ring connecting grooves 1062 on the corresponding sides, and connect the two semicircular auxiliary rings 102 to the circular main ring 101 by bolts, and at the same time, connect the limiting grooves 103 of the two semicircular auxiliary rings 102 to the support ring 201 by bolts.

[0051] Compared with the prior art, the parachute-free airdrop packaging structure according to the present invention can achieve the following beneficial effects:

[0052] First, the application scope of the parachute-free airdrop packaging structure in the present application is wider than that of general airdrop packaging. It is not only suitable for downward delivery from a certain height, but also suitable for parabolic delivery forward from the ground or sea, and also suitable for downward delivery from a slope at a certain height.

[0053] Second, by adopting the spherical structure of the bracket 100, the lightweight of the parachute-free airdrop packaging structure can be significantly achieved, and the bracket 100 has some gaps, which can facilitate the grabbing and delivery of mechanical equipment such as unmanned vehicles, and can maximize the load-bearing capacity and endurance of the aircraft carried.

[0054] Third, by adopting the parachute-free airdrop packaging structure of the present application, the item can be suspended in the center of the spherical device surrounded by the bracket 100, which can better achieve the buffering and anti-collision function when dropping at low altitude.
