Description

Technical Field

[0001] This utility model belongs to the field of drone-related technology, and in particular relates to a sealed cargo container for a heavy-duty drone. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are unmanned aerial vehicles controlled by radio or autonomous programs, and are used in various industries. The cargo container design for heavy-duty UAVs needs to balance structural strength, sealing, lightweight design, environmental adaptability, and ease of operation to meet the needs of logistics, military, and medical transportation scenarios. Currently, UAV cargo containers still have the following drawbacks in practical use:

[0003] First, there is the issue of the airtightness of drones. For example, the transportation of military and medical supplies requires them to be kept sealed, which places certain requirements on the airtightness of the cargo container. In cases such as falling into water or encountering rain, it is necessary to ensure that the materials inside the cargo container are not damaged.

[0004] Secondly, there are certain requirements for the impact resistance and protection performance of the cargo container. Once materials need to be dropped from a height, they cannot fall directly to the ground. To avoid damage to the materials, firstly, the cargo container must have sufficient impact resistance and deformation resistance to prevent the materials from becoming unusable after deformation; secondly, the container must have strong protection for the materials inside. If the container falls, collides, or rolls during the drop process, the materials inside may be damaged and rendered unusable. Therefore, it is necessary to enhance the protection of the materials inside the container.

[0005] Secondly, during rapid transportation, especially for heavy drones, which are large in size and have large cargo containers, and whose cargo containers are mostly square in structure and suspended below the drone, the air resistance generated during transportation is large, which increases energy consumption and reduces transportation efficiency. Utility Model Content

[0006] The purpose of this utility model is to provide a sealed cargo box for heavy-duty drones. By setting up a sealing strip 1, a sealing strip 2, a cargo box, a box lid, an air cushion, an EVA shock-absorbing inner liner, a top airbag, side airbags, a shock-absorbing pad, and an end cap, it solves the problems of insufficient sealing, insufficient impact resistance, insufficient deformation resistance, inadequate protection of the cargo inside the box, and high air resistance during transportation.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to a sealed cargo container for a heavy-duty drone, comprising a cargo box, a lid, an EVA shock-absorbing inner liner, a support plate, and a top airbag. The cargo box is covered by a lid, and one end of the cargo box is fixed with a bullet-shaped end. Corner protectors are attached to both sides of the cargo box away from the end. A shielding film is attached to the inner wall of the cargo box. An EVA shock-absorbing inner liner is installed inside the cargo box inside the shielding film. A support plate is installed at the bottom of the EVA shock-absorbing inner liner. A square-shaped side airbag is installed inside the EVA shock-absorbing inner liner outside the support plate. A top airbag is also installed inside the EVA shock-absorbing inner liner above the side airbag.

[0009] The box cover has two corner protectors attached to the two sides of the end face away from the end head, and a shielding film is attached to the inner wall of the box cover. A shock-absorbing pad is provided inside the box cover inside the shielding film.

[0010] A sealing strip is fixed to the top surface of the material box, and a sealing strip is fixed to the bottom surface of the box lid.

[0011] Furthermore, symmetrically distributed support strips are fixed to the bottom of the support plate, and the bottom surface of the support strips penetrates through the EVA shock-absorbing inner liner and is fixed to the inner bottom surface of the material box.

[0012] Furthermore, the bottom of the supply box is fixed with an air cushion, and the end is hollow inside, with the end facing the direction of the drone's movement.

[0013] Furthermore, symmetrically distributed lifting lugs are fixed on both sides of the material box, and equidistant ear plates are fixed on the upper outer side of the material box and the lower outer side of the box lid. Bolts are inserted between two ear plates on the same vertical line and screwed nuts to lock them in place.

[0014] Furthermore, the top airbag and the side airbags are connected by a hose, and an air tube is fixedly installed inside the box cover. A valve is fixed on the part of the air tube that extends above the box cover, and the lower part of the air tube passes through the shock-absorbing pad and is connected to the top airbag.

[0015] Furthermore, the bottom of the second sealing strip is provided with a sealing groove that matches the size of the first sealing strip, and the first sealing strip is embedded in the sealing groove of the second sealing strip, with the bottom surface of the second sealing strip contacting the upper surface of the material box.

[0016] This utility model has the following beneficial effects:

[0017] This invention solves the problem of insufficient sealing of drone cargo containers by setting up a first sealing strip, a second sealing strip, a supply box, and a box lid. After the supply box is filled with supplies, the box lid is placed on top of the supply box. Both the first and second sealing strips are silicone sealing strips. Pressing down the box lid causes the second sealing strip at the bottom of the box lid to cover the first sealing strip, so that the first sealing strip is completely embedded inside the second sealing strip. This provides a better sealing effect than the single contact sealing of two strips. Furthermore, the upper cross section of the first sealing strip is circular, and the lower cross section is square, with the diameter of the circle being larger than the side length of the square, which further enhances the sealing performance after embedding. This invention changes the conventional long strip sealing structure and makes the sealing performance even better.

[0018] This invention solves the problems of insufficient impact and deformation resistance of drone cargo containers and inadequate protection of the contents by incorporating a cargo box, air cushion, EVA shock-absorbing inner liner, top airbag, side airbag, shock-absorbing pad, and lid. Firstly, the cargo box itself is made of high-strength materials such as aluminum alloy, resulting in minimal deformation. Furthermore, the air cushion at the bottom of the cargo box provides cushioning even during high-altitude drops, and the corner protectors further mitigate side impacts. The other end of the cargo box can withstand high-intensity impacts. Firstly, it can reduce the deformation of the supply box and facilitate the removal of supplies. Secondly, inside the supply box, supplies are placed on a support plate and then completely enclosed by an EVA shock-absorbing inner liner. The EVA shock-absorbing inner liner is the first layer of protection inside. Then, side airbags are set between the outside of the supplies and the inside of the EVA shock-absorbing inner liner, and a top airbag is set on top of the supplies. After the box lid is closed, the top airbag and side airbags are inflated to contact and protect the supplies, providing all-round protection. In addition, after the box lid is closed, the shock-absorbing pad inside the box lid will also provide some protection to the upper layer of supplies, enhancing the protective performance.

[0019] This invention solves the problem of large air resistance caused by the large volume of the cargo container during transportation by setting up an end cap and a cargo box. By pointing the end cap towards the direction of the drone's transportation and designing the end cap in a bullet shape, wind resistance can be minimized, energy consumption can be reduced, and transportation efficiency can be increased.

[0020] This utility model provides a shielding film 1 inside the supply box and a shielding film 2 inside the box lid, which increases the overall shielding and enhances the anti-interference ability. The shielding film can be replaced with other materials for other purposes, such as replacing it with a bulletproof coating to increase the bulletproof effect. Attached Figure Description

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0033] Please see Figure 1-8 As shown, this utility model is a sealed cargo box for a heavy-duty drone, including a cargo box 1, a lid 2, an EVA shock-absorbing inner liner 3, a support plate 4, and a top airbag 5. The cargo box 1 is covered with a lid 2. One end of the cargo box 1 is fixed with a bullet-shaped end 102. Corner protectors 101 are attached to the two sides of the end face of the cargo box 1 away from the end 102. A shielding film 105 is attached to the inner wall of the cargo box 1. An EVA shock-absorbing inner liner 3 is installed inside the cargo box 1 inside the shielding film 105. A support plate 4 is installed at the bottom of the inner side of the EVA shock-absorbing inner liner 3. A square-shaped side airbag 501 is installed inside the EVA shock-absorbing inner liner 3 outside the support plate 4. A top airbag 5 is also installed inside the EVA shock-absorbing inner liner 3 above the side airbag 501.

[0034] The two sides of the end face of the box cover 2 away from the end 102 are attached with corner protectors 201, and the inner wall of the box cover 2 is attached with shielding film 204, and a shock-absorbing pad 205 is provided inside the box cover 2 inside the shielding film 204.

[0035] The top of the supply box 1 is closed by the box cover 2. The end of the supply box 1 is equipped with a bullet-shaped end 102. When the supply box 1 is connected to the drone, the end 102 is oriented towards the direction of the drone's transport to minimize wind resistance.

[0036] When the side of the end of the supply box 1 is subjected to a large impact, the wrap angle 101 on the side of the end of the supply box 1 can effectively buffer the impact force and prevent the supply box 1 from deforming. Similarly, the wrap angle 201 on the side of the end of the lid 2 also has a buffering effect.

[0037] A shielding film 105 is installed inside the material box 1, and a shielding film 204 is installed inside the box lid 2 to increase the overall shielding and enhance the anti-interference ability.

[0038] The materials are placed on the support plate 4 and enclosed by the EVA shock-absorbing inner liner 3. The EVA shock-absorbing inner liner 3 is the first layer of protection inside. Then, side airbags 501 are set between the outside of the materials and the inside of the EVA shock-absorbing inner liner 3. A top airbag 5 is set above the materials. After the lid 2 is closed, the top airbag 5 and the side airbags 501 are inflated to contact and enclose the materials, providing all-round protection for the materials.

[0039] A sealing strip 106 is fixed to the top surface of the supply box 1, and a sealing strip 202 is fixed to the bottom surface of the box cover 2. A sealing groove adapted to the size of the sealing strip 106 is opened at the bottom of the sealing strip 202, and the sealing strip 106 is embedded in the sealing groove of the sealing strip 202. The bottom surface of the sealing strip 202 contacts the upper surface of the supply box 1.

[0040] After the supply box 1 is filled with supplies, place the lid 2 on top of the supply box 1. Then, press down the lid 2 so that the sealing strip 202 at the bottom of the lid 2 covers the sealing strip 106, so that the sealing strip 106 is completely embedded in the sealing groove inside the sealing strip 202. This is better than the single contact sealing effect of two strips.

[0041] The bottom of the support plate 4 is fixed with symmetrically distributed support bars 401. The bottom surface of the support bars 401 penetrates the inner bottom surface of the EVA shock-absorbing inner liner 3 and the material box 1. The support plate 4 is connected to the material box 1 through the support bars 401 to maintain structural stability. Since the support plate 4 needs to hold materials and its through holes are used to tie up materials with straps and other binding materials, it is necessary to keep the support plate 4 from moving.

[0042] An air cushion 104 is fixed to the bottom of the supply box 1, and the end 102 is hollow inside, with the end 102 facing the direction of the drone's movement.

[0043] The supply box 1 itself is made of materials such as aluminum alloy, which has high strength and little deformation. In addition, an air cushion 104 is set at the bottom of the supply box 1, so that even if the supplies are dropped from a high altitude, the bottom of the supplies will be cushioned by the air cushion 104.

[0044] Symmetrically distributed lifting lugs 103 are fixed on both sides of the material box 1. Equally distributed ear plates 107 are fixed on the upper outer side of the material box 1 and the lower outer side of the box cover 2. Bolts are inserted between two ear plates 107 on the same vertical line and nuts are screwed in to lock them.

[0045] After the lid 2 and the material box 1 are installed, bolts are inserted between the two ear plates 107 that are on the same vertical line, and then nuts are screwed on to lock them. At this time, the lid 2 and the material box 1 are locked. Bolts, nuts, ear plates 107, etc. can also be replaced with fasteners and other components to connect the material box 1 and the lid 2.

[0046] The top airbag 5 and the side airbag 501 are connected by a hose, and an air tube 203 is fixed through the inside of the box cover 2. A valve 2031 is fixed on the part of the air tube 203 that extends out of the box cover 2. The lower part of the air tube 203 passes through the shock-absorbing pad 205 and is connected to the top airbag 5.

[0047] Open valve 2031, connect the upper end of air pipe 203 to external inflation equipment, and inflate air into air pipe 203 to make the top airbag 5 inflate. At the same time, because the top airbag 5 and the side airbags 501 are connected by hoses, the side airbags 501 will be blown up simultaneously, thus providing all-round protection for the materials.

[0048] The specific working principle of this utility model is as follows: First, the supply box 1 itself is made of materials such as aluminum alloy. Then, the supplies are placed on the support plate 4 and enclosed by the EVA shock-absorbing inner liner 3, which serves as the first layer of internal protection. The support plate 4 is connected to the supply box 1 through support strips 401 to maintain structural stability. The through holes on the support plate 4 are used to tie the supplies with straps and other binding materials. Then, the uninflated side airbags 501 are placed around the supplies, and the top airbag 5 is placed on top of the supplies. Next, cover the box with lid 2 and press it down so that the sealing strip 202 at the bottom of lid 2 covers the sealing strip 106, making the sealing strip 106 completely embedded in the sealing groove inside the sealing strip 202. After lid 2 and the material box 1 are covered, insert bolts between the two ear plates 107 that are on the same vertical line, and then tighten the nuts. At this time, lid 2 and material box 1 are locked. Then, open valve 2031 and connect the upper end of air pipe 203 to external inflation equipment to inflate the top airbag. The top airbag 5 inflates, and because the top airbag 5 and the side airbags 501 are connected by hoses, the side airbags 501 are inflated simultaneously, providing all-around protection for the supplies. Finally, the supplies are transported by connecting to a drone via the lifting lug 103, with the end 102 facing the direction of the drone's transport to minimize wind resistance. Finally, during high-altitude drop, if the bottom of the supply box 1 touches the ground, it is cushioned by the air cushion 104; if it is subjected to force on the side, there are also corner protectors 101 and corner protectors 2. 01 buffer, the other end 102 can withstand high-intensity impact, minimizing the deformation of the material box 1. Inside the material box 1, the entire structure is protected by the EVA shock-absorbing inner liner 3, which is the first layer of protection inside. Side airbags 501 are set between the outside of the material and the inside of the EVA shock-absorbing inner liner 3, and a top airbag 5 is set above the material to provide comprehensive secondary protection. After the box lid 2 is closed, the shock-absorbing pad 205 inside the box lid 2 will also provide a third layer of protection for the upper layer of the material.

[0049] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
