The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0035] The embodiment of the present invention provides a drone logistics container, such as Figure 1-7 As shown, the drone logistics container includes a logistics container body 1, and the logistics container body 1 is composed of a plurality of unit cabinets 10 for storing logistics goods; the unit cabinet 10 includes a cabinet body 11 and a storage room 12, a first installation room 14, and a second installation room 16 divided by the cabinet body 11; the front side of the cabinet body 11 is provided with a storage port for storing and retrieving logistics goods, and a cabinet door 13 is hingedly installed; wherein, the storage room 12 is used to place logistics goods, the first installation room 14 is equipped with a cargo depositing mechanism 2 for transferring goods into the storage room 12, and the second installation room 16 is equipped with a cargo pushing mechanism 4 for pushing goods out of the storage room 12 when the drone picks up the goods.

[0036] In this embodiment, an innovative drone logistics container design (logistics container body 1) is presented. The core of the design is that through fine structural division and integration of automated mechanisms, efficient and automated handover of goods between drones and containers is achieved, significantly improving the efficiency and safety of logistics distribution (unit cabinet 10). The container is composed of multiple independent unit cabinets 10, and the internal space of each unit cabinet 10 is cleverly divided into a storage room 12, a first installation room 14 and a second installation room 16. The storage room 12 is used as a storage area for logistics goods. The front side of the storage room 12 is provided with a storage and access port, and the goods are stored and accessed through a hinged cabinet door 13. The bottom edge of the cabinet door 13 is hinged to the cabinet body 11, and two side baffles 15 are fixedly installed on the inside. When the cabinet door 13 is opened to a horizontal state, it can be used as a placement platform for drones to transport goods, ensuring the stability and safety of the goods handover. The cargo storage mechanism 2 assembled in the first installation room 14 realizes the automated transmission of goods from the storage and access port to the storage room 12 through a series of transmission devices, avoiding the tediousness and potential errors of manual operation.

[0037] The cargo pushing mechanism 4 installed in the second installation chamber 16 pushes the cargo smoothly out of the storage chamber 12 through precise mechanical linkage and driving mechanism when the drone picks up the cargo, so as to facilitate the drone to grab the cargo and ensure efficient and smooth cargo delivery.

[0038] In addition, the second support roller 27 provided in the third installation chamber 17 inside the cabinet 11, and the protruding structure on the cabinet door 13 and the bottom inner wall of the storage chamber 12 effectively avoid direct friction between the cargo packaging boxes during the storage and retrieval process, and protect the integrity of the cargo. The setting of the cabinet door switch mechanism 3 not only realizes the automatic opening and closing of the cabinet door 13, but also can open the cabinet door 13 to a horizontal state as a release platform for drone cargo, further improving the automation and flexibility of cargo delivery.

[0039] The drone logistics container of this embodiment, through the above-mentioned carefully designed structure and automation mechanism, not only greatly improves the efficiency of drone logistics distribution and reduces the need for manual operation, but also ensures the safety and accuracy of cargo delivery through the automated control of the cargo storage and push-out mechanism. In addition, the refined management and intelligent control inside the container, such as environmental adjustment and cargo status monitoring, further improves the overall intelligent level of logistics distribution, and plays an important role in promoting the construction of an efficient and intelligent logistics distribution system.

[0040] In a further preferred embodiment of the present invention, a touch screen 101 is provided on the logistics container body 1 for the staff to perform control operations when setting parameters of the equipment.

[0041] In this embodiment, the intelligent operation of the logistics container body 1 has been significantly improved. By setting a touch screen 101 on the logistics container body 1, the staff can intuitively and conveniently set parameters and operate the equipment. As an important interface for human-computer interaction, the touch screen 101 not only simplifies the operation process and improves the operation efficiency, but also makes the setting and monitoring of the equipment more intuitive and humane, further enhancing the intelligence level of the logistics container. In an emergency, the staff can also quickly take countermeasures through the touch screen 101, such as emergency stop of cargo storage and retrieval operations, to ensure the safety of equipment and cargo.

[0042] In a further preferred embodiment of the present invention, the bottom edge of the cabinet door 13 is hinged to the cabinet body 11, and two side baffles 15 are fixedly installed on the inner side of the cabinet door 13. When the cabinet door 13 is opened in a horizontal state, it is used as a placement platform for drones to transport goods.

[0043] In this embodiment, the structural design of the cabinet door 13 has been innovatively optimized, and its bottom edge is hinged to the cabinet body 11, so that the cabinet door 13 can be opened and closed smoothly, and the two side baffles 15 fixedly installed on the inner side of the cabinet door 13 can form a stable platform together when the cabinet door 13 is opened to a horizontal state, which is used as a placement area for drones to deliver goods. This design not only simplifies the cargo handover process between drones and logistics containers and improves the handover efficiency, but also effectively prevents the cargo from slipping or shifting during the placement or removal process through the setting of the side baffles 15, ensuring the safety of the cargo and the accuracy of the handover.

[0044] In a further preferred embodiment of the present invention, the cargo deposit mechanism 2 includes: a plurality of first support rollers 21 arranged in parallel and all arranged in the first installation chamber 14, and both ends of the first support rollers 21 are fixedly mounted with a central shaft 22 rotatably connected to the side wall of the first installation chamber 14; a plurality of double-groove pulleys 23 respectively fixedly mounted on the plurality of central shafts 22 located at the same end of the first support rollers 21, and a belt 24 is sleeved between the double-groove pulleys 23 on two adjacent first support rollers 21, and the adjacent first support rollers 21 are transmitted through the belt 24 and the double-groove pulleys 23; a reduction motor 25 fixedly mounted in the first installation chamber 14, and a first bevel gear 26 is fixedly sleeved on the output shaft of the reduction motor 25 and any one of the central shafts 22, and the two first bevel gears 26 are meshed with each other.

[0045] In this embodiment, the design of the cargo deposit mechanism 2 improves the automation and operation efficiency of the logistics container. The mechanism constructs an efficient and stable cargo conveying system through a plurality of parallel first support rollers 21 arranged inside the first installation chamber 14, and components such as the central shaft 22, double-groove pulley 23, belt 24 and reduction motor 25 connected thereto. Specifically, the first support roller 21 is rotatably connected to the side wall of the first installation chamber 14 through the central shaft 22 at both ends, ensuring the smooth rotation of the support roller and the smooth transmission of the cargo. The double-groove pulley 23 is fixedly sleeved at one end of each first support roller 21, and is connected to the double-groove pulley 23 on the adjacent first support roller 21 through the belt 24, forming a continuous transmission chain, so that power can be transmitted from one first support roller 21 to another first support roller 21, realizing the automatic transmission of the cargo in a direction perpendicular to the first support roller 21. The reduction motor 25 serves as a power source, and a first bevel gear 26 is fixedly sleeved on its output shaft. By meshing with another first bevel gear 26 fixed on the central shaft 22, the rotational power of the motor is efficiently transmitted to the support roller system, ensuring a smooth and efficient cargo storage process.

[0046] In a further preferred embodiment of the present invention, a third installation chamber 17 is further provided in the cabinet body 11, and a plurality of second support rollers 27 are rotatably installed, the second support rollers 27 protrude from the bottom inner wall of the storage chamber 12, and the first support rollers 21 protrude from the inner side of the cabinet door 13 (with Figure 2 perspective) to avoid direct friction between the cargo packaging box and the cabinet door 13 and the bottom inner wall of the storage chamber 12.

[0047] In this embodiment, by providing a third installation chamber 17 in the cabinet body 11 and rotatably installing a plurality of second support rollers 27 therein, as well as an ingenious design of the first support rollers 21 on the cabinet door 13, direct friction between the cargo packaging box and the cabinet door 13 and the bottom inner wall of the storage chamber 12 during storage and retrieval is effectively avoided, thereby significantly improving the integrity of the cargo and the service life of the logistics container.

[0048] Specifically, the second support roller 27 is provided so that the goods can slide smoothly on the support roller during the placement and movement of the goods in the storage chamber 12, reducing the friction and wear caused by direct contact, protecting the outer packaging of the goods from damage, and reducing the wear of the inner wall of the storage chamber 12, thereby extending the service life of the logistics container. The protruding design of the first support roller 21 on the inner side of the cabinet door 13 also plays a similar role. When the goods are stored and retrieved through the cabinet door 13, the friction between the goods and the cabinet door 13 can be effectively reduced, ensuring the safety and integrity of the goods during the entry and exit process, and also helping to maintain the structural integrity and sealing performance of the cabinet door 13.

[0049] In another embodiment of the present invention, two symmetrically arranged cabinet door switch mechanisms 3 are further provided on the cabinet body 11 and the cabinet door 13, which are used to close the cabinet door 13 and to open the cabinet door 13 to a horizontal state, so that the cabinet door 13 is used as a release platform for the drone to transport goods. The cabinet door switch mechanism 3 includes: a fixed shaft 31 fixedly mounted on the inner wall of one side of the cabinet body 11; a rotating block 32 rotatably mounted on the fixed shaft 31; a first electric push rod 33 fixedly mounted on the rotating block 32, and a hinge block 34 is hinged on the output rod of the first electric push rod 33, and the hinge block 34 is fixedly connected to the side baffle 15. When the output rod of the first electric push rod 33 is extended, the cabinet door 13 is opened.

[0050] In this embodiment, the design of the door switch mechanism 3 further improves the level of automated operation of the logistics container and the efficiency of drone cargo delivery. The two symmetrically arranged door switch mechanisms 3 on the cabinet body 11 and the door 13 not only realize the automated opening and closing of the door 13, but also open the door 13 to a horizontal state, making it a release platform for drone cargo delivery, significantly simplifying the drone cargo pick-up and placement operations, and improving the flexibility and efficiency of logistics distribution.

[0051] Specifically, the cabinet door switch mechanism 3 includes a fixed shaft 31 fixed on the inner wall of one side of the cabinet body 11, a rotating block 32 rotatably sleeved on the fixed shaft 31, and a first electric push rod 33 fixedly mounted on the rotating block 32. The output rod of the first electric push rod 33 is hinged with a hinge block 34, and the hinge block 34 is fixedly connected to the side baffle 15. When the output rod of the first electric push rod 33 is extended, the cabinet door 13 can be smoothly opened to a horizontal state through the linkage of the hinge block 34, forming a stable platform, which is convenient for the drone to release and grab the cargo.

[0052] In another embodiment of the present invention, the cargo pushing mechanism 4 includes: two telescopic frames 41 arranged symmetrically in the second installation chamber 16, two connecting ports are arranged between the second installation chamber 16 and the storage chamber 12 for extending the two telescopic frames 41; a push plate 42 located in the storage chamber 12, and two vertically arranged sliding rods 43 are fixedly installed on one side of the push plate 42; two first fixed blocks 44 respectively fixedly mounted on the two sliding rods 43 and fixed to the push plate 42, and the two first fixed blocks 44 are respectively hinged to one end of the two telescopic frames 41 located at the bottom; two sliders 45 respectively slidably mounted on the two sliding rods 43, and the two sliders 45 are respectively hinged to one end of the two telescopic frames 41 located at the top; two second fixed blocks 46 both fixedly mounted on the inner wall of the second installation chamber 16, and the two second fixed blocks 46 are respectively hinged to the other end of the two telescopic frames 41 located at the bottom; two lifting blocks 47 respectively hinged to the other end of the two telescopic frames 41 located at the top; and a driving mechanism for driving the two lifting blocks 47 to rise and fall so that the two telescopic frames 41 can be extended and retracted.

[0053] In this embodiment, the design of the cargo push-out mechanism 4 significantly improves the automation and operational efficiency of the logistics container during the cargo outbound process. The mechanism constructs an efficient and stable cargo push-out system by setting two symmetrical telescopic frames 41 in the second installation chamber 16, combining components such as a push plate 42, a slide bar 43, a first fixed block 44, a slider 45, a second fixed block 46 and a lifting block 47. Specifically, through the telescopic movement of the telescopic frame 41, the horizontal movement of the push plate 42 in the storage chamber 12 can be accurately controlled to achieve automatic push-out of the cargo, simplify the cargo outbound process, and improve operational efficiency. The setting of the driving mechanism further enhances the automation capability of the cargo push-out mechanism 4. By driving the lifting and lowering of the two lifting blocks 47, the telescopic movement of the telescopic frame 41 can be accurately controlled to achieve smooth push-out of the cargo, avoid the risk of damage to the cargo during the outbound process, and improve the safety and reliability of logistics distribution.

[0055] In this embodiment, the ingenious design of the driving mechanism further improves the automation level and operation accuracy of the cargo push-out mechanism 4, ensuring the efficiency and reliability of the logistics container in the process of cargo out of the warehouse. The driving mechanism constructs a precise and stable power transmission system through components such as a servo motor 51, a main sprocket 52, a transmission sprocket 53, a chain 54, a threaded rod 50, a limit rod 49 and a support block 48. Specifically, the servo motor 51 serves as a power source, and the two main sprockets 52 fixedly installed at the bottom end of its output shaft are connected to the chain 54 on the transmission sprocket 53, so as to efficiently transmit power to the two threaded rods 50, thereby realizing precise control of the lifting block 47.

[0056] The threaded connection between the threaded rod 50 and the lifting block 47, and the sliding fit between the lifting block 47 and the limiting rod 49, ensure the stability and accuracy of the lifting block 47 during the up and down movement, thereby accurately controlling the telescopic action of the telescopic frame 41 and realizing the smooth pushing of the push plate 42 to the goods. The setting of the support block 48 not only provides a stable support for the limiting rod 49 and the threaded rod 50, but also ensures the structural stability and mechanical strength of the entire driving mechanism through the connection with the second fixed block 46.

[0057] The present invention also provides a drone delivery platform, such as Figure 8-11 As shown, the drone delivery platform is applied to the above-mentioned drone logistics container, and the drone delivery platform includes: a drone body 9 provided with support legs 901 and reinforcing longitudinal rods 902, and the reinforcing longitudinal rods 902 are fixedly installed on the support legs 901; a cargo grabbing mechanism 6 arranged on two parallel reinforcing longitudinal rods 902, which is used to grab the logistics cargo to be transported.

[0058] In this embodiment, the innovative design of the drone delivery platform significantly enhances the automated delivery capability and cargo handling efficiency of the drone logistics container. The platform constructs an efficient and stable cargo grabbing and delivery system by setting support legs 901 and reinforcing longitudinal rods 902 on the drone body 9, and installing cargo grabbing mechanisms 6 on the parallel reinforcing longitudinal rods 902. Specifically, the support legs 901 not only provide stable take-off and landing and support for the drone, but also enhance the structural stability and carrying capacity of the drone by strengthening the connection of the longitudinal rods 902, ensuring safety during cargo grabbing and delivery.

[0059] The setting of the cargo grabbing mechanism 6 realizes the automatic grabbing and releasing of the logistics cargo by the drone, simplifies the cargo handover process, improves the distribution efficiency, and meets the needs of the modern logistics industry for high-efficiency and automated distribution. In addition, the coordinated use of the drone delivery platform and the logistics container not only realizes the automatic storage and handover of the cargo, but also significantly expands the coverage of logistics distribution through the remote distribution capability of the drone, improves the flexibility and adaptability of logistics distribution, and provides important technical support for the construction of an intelligent and efficient logistics distribution system.

[0060] In a further preferred embodiment of the present invention, the cargo grabbing mechanism 6 includes: a mounting seat 61 fixedly mounted between two reinforcing longitudinal rods 902, a slide groove being provided at the bottom of the mounting seat 61; a bidirectional screw 62 rotatably mounted on the inner walls on both sides of the slide groove of the mounting seat 61, the bidirectional screw 62 being provided with two sections of symmetrically arranged and oppositely rotating threads; a clamping motor 63 fixedly mounted on the top of the mounting seat 61; two second bevel gears 64 fixedly mounted on the output shaft of the clamping motor 63 and the bidirectional screw 62, the two second bevel gears 64 being meshed with each other; two moving seats 65 threadedly mounted on the bidirectional screw 62 and symmetrically arranged; two clamping plates 66 respectively fixedly mounted on the bottom of the two moving seats 65, the two clamping plates 66 being symmetrically arranged.

[0061] In this embodiment, the cargo grabbing mechanism 6 improves the automation level and cargo handling efficiency of the drone delivery platform. The mechanism constructs an efficient and stable cargo grabbing and releasing system through components such as a chute opened at the bottom of the mounting seat 61, a rotatably mounted bidirectional screw 62, a clamping motor 63, a second bevel gear 64, a threaded movable seat 65, and a symmetrically arranged clamping plate 66. Specifically, the clamping motor 63 drives the bidirectional screw 62 to rotate through the transmission of the second bevel gear 64, and then through the cooperation of the thread and the movable seat 65, the two movable seats 65 are moved toward or away from each other in the chute, and the clamping and release of the cargo by the clamping plate 66 is controlled.

[0062] This design not only significantly improves the automation level of cargo grabbing and releasing, simplifies the cargo handover process between drones and logistics containers, but also significantly reduces the risk of damage to cargo during grabbing and releasing by improving the accuracy and reliability of operations, thereby improving the safety and efficiency of logistics distribution. In addition, the symmetrical design of the bidirectional screw 62 ensures the synchronization and stability of the movement of the two moving seats 65, thereby enhancing the balance and safety of the cargo grabbing process.

[0063] In a further preferred embodiment of the present invention, a rubber pad 67 is fixedly installed on one side of the two clamps 66 that are close to each other, so as to improve the anti-slip ability and thereby improve the stability of the two clamps 66 in clamping the goods, and a thin film pressure sensor 68 is embedded on the two rubber pads 67 to monitor the clamping force and avoid damage to the goods due to excessive clamping force.

[0064] In this embodiment, the stability and safety of the cargo grabbing mechanism 6 during cargo clamping are significantly improved by fixing a rubber pad 67 on the side where the two clamping plates 66 are close to each other and embedding a film pressure sensor 68 on the rubber pad 67. Specifically, the provision of the rubber pad 67 not only improves the friction coefficient between the contact surface of the clamping plate 66 and the cargo, effectively preventing the cargo from sliding during the clamping process and ensuring stable clamping of the cargo, but also provides buffer protection for the cargo through its elastic characteristics, avoiding possible damage to the cargo caused by direct clamping of hard materials.

[0065] The embedded film pressure sensor 68 realizes real-time monitoring of the clamping force, ensures the appropriateness and uniformity of the clamping force, avoids unnecessary damage to the goods due to excessive clamping force, and improves the safety and reliability of cargo handling. This design not only significantly improves the intelligence level of the cargo grabbing mechanism 6 and realizes precise control of the cargo clamping process, but also significantly reduces the risk of cargo grabbing and handling by improving the safety and stability of the operation, and improves the efficiency and quality of logistics distribution.

When the output rod of the second electric push rod 76 is shortened to the shortest, the plug rod 77 is disengaged from the slots 78.

[0067] In this embodiment, the anti-fall mechanism 7 design of the drone delivery platform significantly improves the safety and stability of the cargo during drone delivery. The anti-fall mechanism 7 constructs a reliable and flexible anti-fall protection system through components such as four mounting blocks 71 fixedly mounted on the four supporting legs 901 of the drone body 9, a rotatably mounted rotating shaft 72, a fixedly sleeved anti-fall plate 73, and a fixedly mounted stepper motor 74. Specifically, the stepper motor 74 controls the opening and closing of the anti-fall plate 73 by driving the rotation of the rotating shaft 72, thereby achieving effective protection and release of the cargo.

[0068] The second electric push rod 76 fixedly installed in the installation groove 75 opened on the anti-fall plate 73, and the coordinated use of the plug rod 77 and the slot 78 connected thereto, further enhance the stability and reliability of the anti-fall mechanism 7. During the cargo transportation process, the output rod of the second electric push rod 76 is extended, so that the plug rod 77 and the slot 78 are matched, ensuring the closure of the anti-fall plate 73, effectively preventing the accidental drop of the cargo during the drone transportation process, and protecting the safety of the cargo. When the cargo needs to be released, the output rod of the second electric push rod 76 is shortened to the shortest, so that the plug rod 77 is separated from the slot 78, and the anti-fall plate 73 is opened under the control of the stepper motor 74, realizing the smooth release of the cargo.

[0069] This design not only significantly improves the safety of the drone delivery platform during cargo delivery, reduces damage and safety issues caused by cargo falling in the air, but also significantly improves the efficiency and customer satisfaction of logistics distribution by improving the flexibility and reliability of operation. In addition, the coordinated use of the anti-fall mechanism 7 and the cargo grabbing mechanism 6 not only realizes the automatic storage, grabbing and release of cargo, but also significantly improves the intelligence level and overall efficiency of logistics distribution by improving the safety and stability of cargo handling, and meets the needs of the modern logistics industry for high efficiency and safe operation.
