Description

Technical Field

[0001] This invention relates to the field of drone packaging technology, specifically to a drone packaging box for transport vehicles. Background Technology

[0002] The use of packaging boxes for drones is primarily based on four core needs: transportation protection, storage management, safety compliance, and brand display. The design must balance functionality, safety, and user experience. Drone bodies and precision components are sensitive to vibration and impact. The interior of the packaging box typically uses materials such as EVA foam, honeycomb cardboard, or air cushions, and uses customized grooves to fix the drone components, reducing the risk of collisions during transportation. When in use, traditional drone packaging boxes usually restrict the drone's position to prevent it from shifting due to vibration inside the box during transportation.

[0003] To overcome the above-mentioned defects, existing technology 1 (Chinese patent with announcement number CN221115055U, announcement date June 11, 2024) provides a packaging device for surveying drones. This packaging device includes a packaging box, with a storage unit fixedly connected inside the box. A storage spring is fixedly connected to the inner wall of the front of the storage unit, a snap-fit ​​post is fixedly connected to the back of the storage spring, a connecting post is fixedly connected to the back of the snap-fit ​​post, and a fixed handle is fixedly connected to the front of the connecting post. A sealing cover is inserted into the upper end of the packaging box, a support handle is rotatably connected to the outer wall of the sealing cover, a connecting plate is fixedly connected to the lower end of the sealing cover, and a sliding structure is fixedly connected to the lower end of the sealing cover near the back of the connecting plate. A damper assembly is connected to the inner wall of the lower end of the packaging box. This device has the advantages of conveniently storing the surveying drone, providing shock absorption, and offering good protection for the surveying drone, thus effectively... This invention effectively solves the problems and shortcomings of existing devices. Prior art two (Chinese patent with announcement number CN223303200U, announcement date 2025-09-05) describes a packaging box for a fixed-wing drone, comprising: a box body, a box lid, and a limiting component; the box lid is placed above the box body, and a mounting cavity for drone parts is formed between the box lid and the box body; the limiting component is placed inside the box body, and the limiting component has a fuselage engaging slot, a wing engaging slot, and a tail engaging slot; the fuselage, wing, and tail are engaged through the fuselage engaging slot, wing engaging slot, and tail engaging slot respectively, fixing the position of the fuselage, wing, and tail within the box body, so that the drone parts such as the fuselage, wing, and tail remain relatively stationary during storage and transportation, preventing damage to the drone parts due to mutual collisions, improving the protection effect of the drone parts during storage and transportation, and ensuring the surface integrity of the drone parts.

[0004] The aforementioned mechanism uses limiting components to keep drone parts relatively stationary during storage and transportation. However, in actual use, the packaging box itself may shift its position due to vibration and collision. In this case, the drone and parts placed inside the packaging box may collide and cause the parts to detach from the foam layer. Summary of the Invention

[0005] The purpose of this invention is to provide a drone packaging box for transport vehicles, in order to solve the problem mentioned in the background art that, during actual use, the packaging box itself may shift its position due to vibration and collision, and at this time, the drone and components placed inside the packaging box may collide and cause the components to detach from the foam layer.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a packaging box for a transport vehicle drone, comprising a packaging box body, an internal protective layer thereof, and a packaging box lid hinged to the side of the packaging box body, wherein an EVA foam layer is provided inside the packaging box lid, and locking components are provided on the surfaces of both the packaging box body and the packaging box lid; a fixed base plate is provided at the bottom of the packaging box body, and positioning mechanisms for assisting in fixing the packaging box body are provided at the four corners of the fixed base plate; a limiting mechanism for preventing the packaging box body from shifting position is provided at the middle position of the top of the fixed base plate; and a closing mechanism for preventing the locking components from loosening is provided on the surfaces of both the packaging box body and the packaging box lid.

[0007] Furthermore, the positioning mechanism includes a positioning rod, which is fixedly connected to the four corners at the top of the fixed base plate. A pull rod is slidably connected inside the positioning rod, and a piston block is installed at the bottom end of the pull rod. Suction cups are installed at the four corners at the bottom of the fixed base plate. A piston rod is installed on the side of the top of the fixed base plate near the positioning rod, and a protrusion is installed on the side of the piston rod. The protrusion is located at the top of the pull rod. A placement rack is engaged with the bottom of the packaging box body, and an elastic airbag is fixedly connected to the bottom of the placement rack. The elastic airbag is connected to the piston rod through a hose.

[0008] Furthermore, a connecting spring is wound around the top of the pull rod, and the pull rod and the positioning rod form an elastic structure through the connecting spring.

[0009] Furthermore, the cross-section of the protrusion is trapezoidal, and the inclined surface of the protrusion is in contact with the side of the pull rod.

[0010] Furthermore, a sealing gasket is attached to the top of the positioning rod, and the sealing gasket is sleeved on the outside of the pull rod. A fixing hole is opened at the top of the positioning rod, and the bottom end of the sealing gasket is attached to the fixing hole.

[0011] Furthermore, bottom support rods are installed on both the left and right sides of the bottom of the packaging box body, and rotating frames are provided on both the left and right sides of the top of the fixed base plate, with limit rods rotatably connected between the rotating frames.

[0012] Furthermore, the inner side of the limiting rod is in contact with the outer side of the bottom support rod, and a pad is provided on the side of the bottom end of the limiting rod.

[0013] Furthermore, the limiting rod is inclined in a "C" shape when not in use, and is horizontal in a "C" shape when the inner side of the limiting rod is in contact with the outer side of the bottom support rod.

[0014] Furthermore, the locking assembly at the front end of the packaging box body is provided with mounting boxes on both the left and right sides. Gears are rotatably connected inside the mounting boxes, and a push rod is installed on the top side of the mounting box. The push rod passes through and extends into the interior of the mounting box, and a first rack meshes with the gear at the bottom end of the push rod. A second rack meshes with the gear on the other side. Conductive plates are provided at the top of the second rack and the top of the interior of the mounting box. The two conductive plates correspond to each other. The first rack and the second rack are slidably connected inside the mounting box. Electromagnets are provided at the joint between the packaging box body and the packaging box lid.

[0015] Furthermore, a torsion spring is wound around the front end of the gear, and the gear and the mounting box form an elastic structure through the elastic force of the torsion spring.

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

[0017] 1. By pressing the pull rod, the bottom end of the pull rod moves downward and simultaneously pushes the piston block to move. At the same time, the packaging box body is pressed, causing the suction cups at the four corners at the bottom of the packaging box body to be squeezed and the internal air to be expelled. This achieves basic fixation of the packaging box body in position. In this state, the position of the packaging box body can be adjusted according to different needs to better realize the delivery of drones.

[0018] Furthermore, after the gas is discharged, the piston block moves into the suction cup and automatically resets due to the elasticity of the connecting spring. The squeezing force forces the remaining gas inside the suction cup into the positioning rod. When the piston block resets, it can squeeze the gas upward into the positioning rod. The gas inside the positioning rod moves upward due to the movement of the piston block. The fixing hole at the top of the positioning rod allows the remaining gas inside the positioning rod to be discharged. The sealing gasket at the top of the positioning rod can seal and block the fixing hole, thereby achieving basic fixation of the packaging box body itself.

[0019] Furthermore, the placement rack can provide basic positional restraint for the packaging box. The placement rack moves downwards due to the weight of the packaging box, and as it moves downwards, it compresses the elastic airbag. The gas inside the elastic airbag is then delivered to the piston rod through the hose. As a result, the output end of the piston rod pushes the protrusion outwards. After being pushed out, the protrusion can compress the top of the pull rod. By using the protrusion to restrain the position of the pull rod and the piston block, the suction cup can stably fix the packaging box body in position, improving the overall stability during use.

[0020] 2. The bottom support rod is driven downward by the packaging box body, and the bottom end of the bottom support rod contacts the bottom end of the inner side of the limiting rod, so that the limiting rod is in a horizontal "C" shape. The upper end of the inner side of the limiting rod is engaged with the outer side of the bottom support rod to fix the bottom support rod in position.

[0021] Furthermore, when the first rack moves, it meshes with the gear, allowing the gear to rotate. When the gear rotates, it meshes with the second rack and moves upward. The conductive plate at the top of the second rack and the conductive plate inside the mounting box adhere to each other, making the circuit connected. After the circuit is connected, the electromagnet generates magnetic force, which causes the packaging box body and the packaging box lid to attract each other, preventing the locking component from becoming loose after locking, which would result in the packaging box body and the packaging box lid not being locked securely.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1: As Figure 1 - Figure 3 , Figure 7 and Figure 8The technical solution shown addresses the issue that the packaging box itself may shift due to vibration and collision, potentially causing the drone and components inside to detach from the foam layer. The drone packaging box for a transport vehicle discloses a positioning mechanism, including a packaging box body 1. The packaging box body 1 has a protective layer 2 inside, and a packaging box lid 4 is hinged to the side of the packaging box body 1. The packaging box lid 4 has an EVA foam layer 5 inside, and locking components 3 are provided on the surfaces of both the packaging box body 1 and the packaging box lid 4. A fixed base plate 15 is provided at the bottom of the packaging box body 1, and positioning mechanisms for securing the packaging box body 1 are provided at the four corners of the fixed base plate 15. The positioning mechanisms include positioning rods 19, which are fixedly connected to the four corners at the top of the fixed base plate 15. A pull rod 21 is slidably connected inside the positioning rod 19. A piston block 22 is installed at the bottom end of rod 21. Suction cups 20 are installed at the four corners of the bottom end of the fixed base plate 15. A piston rod 18 is installed on the side of the top of the fixed base plate 15 near the positioning rod 19, and a protrusion 25 is installed on the side of the piston rod 18. The protrusion 25 is located at the top of the pull rod 21. A placement rack 16 is snapped into the bottom end of the packaging box body 1, and an elastic airbag 17 is fixedly connected to the bottom end of the placement rack 16. The elastic airbag 17 is connected to the piston rod 21 through a hose. The 8-phase connection is as follows: the top of the pull rod 21 is wound with a connecting spring 24, and the pull rod 21 and the positioning rod 19 form an elastic structure through the connecting spring 24; the cross-section of the protrusion 25 is trapezoidal, and the inclined surface of the protrusion 25 is in contact with the side of the pull rod 21; the top of the positioning rod 19 is in contact with a sealing gasket 23, and the sealing gasket 23 is sleeved on the outside of the pull rod 21; the top of the positioning rod 19 is provided with a fixing hole, and the bottom end of the sealing gasket 23 is in contact with the fixing hole.

[0034] In this example, such as Figure 1 As shown, the drone requiring protection is placed inside the packaging box body 1. The protective layer 2 restricts the various components of the drone, preventing them from shifting inside the packaging box body 1 and thus ensuring adequate protection. Then, the packaging box lid 4 is connected to the packaging box body 1, and the locking component 3 locks the packaging box body 1 and the packaging box lid 4 together. Simultaneously, the protective layer 2 protects the tops of the drone components, effectively preventing them from contacting the inside of the packaging box lid 4 due to vibration. Figure 3As shown, the packaging box body 1 is placed in the desired installation position, and then the pull rod 21 is pressed, causing the bottom end of the pull rod 21 to move downwards and simultaneously push the piston block 22 to move. At the same time, the packaging box body 1 is pressed, causing the suction cups 20 at the four corners of the bottom of the packaging box body 1 to be squeezed and the internal air to be discharged. After the gas is discharged, the piston block 22 moves into the inside of the suction cup 20 and automatically resets by the elastic force of the connecting spring 24. The squeezing force causes the remaining gas inside the suction cup 20 to be squeezed into the inside of the positioning rod 19. When the piston block 22 resets, it can squeeze the gas upwards into the inside of the positioning rod 19. The gas inside the positioning rod 19 moves upwards due to the movement of the piston block 22. The fixing hole opened at the top of the positioning rod 19 can be used to discharge the remaining gas inside the positioning rod 19. The sealing gasket 23 set at the top of the positioning rod 19 can seal and block the fixing hole, thereby achieving basic fixation of the packaging box body 1 in its own position.

[0035] It should be noted that, as Figure 9 As shown, by placing the entire packaging box inside the placement rack 16, the placement rack 16 can provide basic positional constraint on the packaging box. The placement rack 16 moves downward due to the weight of the packaging box. As the placement rack 16 moves downward, it compresses the elastic airbag 17. The gas inside the elastic airbag 17 is then delivered to the piston rod 18 through the hose. Therefore, the output end of the piston rod 18 pushes the protrusion 25 outward. After being pushed out, the protrusion 25 can compress the top of the pull rod 21, thereby causing the piston block 22 at the bottom of the pull rod 21 to move above the suction cup 20. The piston block 22 seals and blocks the top of the suction cup 20, effectively preventing the gas inside the positioning rod 19 from seeping into the top of the suction cup 20. By using the protrusion 25 to restrict the position of the pull rod 21 and the piston block 22, the suction cup 20 can stably fix the packaging box body 1 in position, improving the overall stability during use.

[0036] Example 2: Figure 1 - Figure 3 , Figure 6 and Figure 9The technical solution shown addresses the issue of uneven force on the elastic airbag 17 when it is pressed due to potential positional shift during packaging placement. The packaging box for the transport vehicle drone discloses a limiting mechanism. A limiting mechanism to prevent positional shift of the packaging box body 1 is provided at the middle position of the top of the fixed base plate 15. Bottom support rods 14 are installed on both the left and right sides of the bottom of the packaging box body 1, and rotating frames 26 are provided on both the left and right sides of the top of the fixed base plate 15. A limiting rod 27 is rotatably connected between the rotating frames 26. The inner side of the limiting rod 27 is in contact with the outer side of the bottom support rod 14, and a pad 28 is provided on the side of the bottom end of the limiting rod 27. When not in use, the limiting rod 27 is in an inclined "C" shape, and when the inner side of the limiting rod 27 is in contact with the outer side of the bottom support rod 14, it is in a horizontal "C" shape.

[0037] In this example, such as Figure 6 As shown, the bottom end of the bottom support rod 14 presses against the side of the limiting rod 27. When not pressed, the limiting rod 27 forms an inclined "C" shape. The bottom support rod 14 is driven downwards by the packaging box body 1, and the bottom end of the bottom support rod 14 contacts the bottom end of the inner side of the limiting rod 27, thus making the limiting rod 27 a horizontal "C" shape. The upper end of the inner side of the limiting rod 27 engages with the outer side of the bottom support rod 14, fixing the bottom support rod 14 in position. Torsion springs are wound around both the front and rear ends of the limiting rod 27. These torsion springs assist in repositioning the limiting rod 27 during subsequent disassembly, increasing the overall flexibility during use. Figure 6 As shown, a pad 28 is provided at the bottom of the limiting rod 27. The pad 28 can support the bottom of the limiting rod 27, preventing the limiting rod 27 from being pressed too much after being pressed. This allows the limiting rod 27 to remain horizontal after being pressed, thereby enabling the bottom support rod 14 to stably limit its own position.

[0038] Example 3: Figure 1 , Figure 2 , Figure 4 and Figure 5The technical solution shown addresses the problem that the locking component 3 may become loose after prolonged use due to damage after the packaging box body 1 and packaging box lid 4 are closed. The packaging box for the transport vehicle drone discloses a closing mechanism. The surfaces of the packaging box body 1 and packaging box lid 4 are equipped with a closing mechanism to prevent the locking component 3 from becoming loose. Mounting boxes 6 are provided on both sides of the locking component 3 at the front end of the packaging box body 1. Gears 7 are rotatably connected inside the mounting boxes 6, and a push rod 9 is installed on the side of the top of the mounting box 6. The push rod 9 passes through and extends to the mounting box. Inside the box 6, electromagnets 13 are installed at the joints of the packaging box body 1 and the packaging box lid 4. The bottom end of the push rod 9 is provided with a first rack 10 that meshes with the gear 7. The other side of the gear 7 is provided with a second rack 11. The top of the second rack 11 and the top of the inside of the mounting box 6 are provided with conductive plates 12. The two conductive plates 12 correspond to each other. The first rack 10 and the second rack 11 are slidably connected inside the mounting box 6. A torsion spring 8 is wound around the front end of the gear 7, and the gear 7 and the mounting box 6 form an elastic structure through the elastic force of the torsion spring 8.

[0039] In this example, such as Figure 4 As shown, when the packaging box body 1 and the packaging box lid 4 are closed, the pressing block at the front end of the packaging box lid 4 presses the push rod 9, causing the push rod 9 to move downward and push the first rack 10 to move synchronously. When the first rack 10 moves, it meshes with the gear 7, allowing the gear 7 to rotate. When the gear 7 rotates, it meshes with the second rack 11 and moves upward. The conductive sheet 12 at the top of the second rack 11 and the conductive sheet 12 inside the mounting box 6 are attached to each other, making the circuit connected. After the circuit is connected, the electromagnet 13 generates magnetic force, which causes the packaging box body 1 and the packaging box lid 4 to attract each other, preventing the locking component 3 from becoming loose after locking, which would result in the packaging box body 1 and the packaging box lid 4 not being locked securely.

[0040] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
