Description

Technical Field

[0001] This application relates to the field of drone delivery technology, and in particular to a logistics box and drone delivery system. Background Technology

[0002] With the surge in demand for logistics and the development of drone manufacturing technology, drones have been widely used in logistics and delivery services. Compared to ground transportation, drones offer advantages such as lower cost, more flexible scheduling, and higher efficiency.

[0003] In existing technologies, logistics boxes are delivered to customers along with the goods during each delivery mission, which requires higher costs and a greater depreciation rate. In addition, the efficiency of picking up food is low, and they do not have an advantage in terms of cost, quality control and customer experience. Summary of the Invention

[0004] This application provides a logistics box and a drone delivery system to solve the problem of low food retrieval efficiency in the prior art.

[0005] The first aspect of this application provides a logistics box, including a box body, a transmission mechanism, and a bottom door. The box body includes a bottom opening, the transmission mechanism is installed on the box body, and the bottom door is slidably disposed on the bottom opening and connected to the transmission mechanism. The bottom door can open or close the bottom opening under the drive of the transmission mechanism.

[0006] In one possible design, the transmission mechanism includes a drive rod and a connecting rod, one end of which is connected to the drive rod and the other end of which is connected to the bottom door. The drive rod can drive the connecting rod to rotate, thereby driving the bottom door to open or close the bottom opening.

[0007] In one possible design, the drive rod includes a first rod and a second rod, with one end of the first rod and the second rod rotatably connected, the other end of the first rod rotatably connected to the housing, and the other end of the second rod rotatably connected to the linkage rod. The first rod and the second rod are capable of rotating relative to each other about their connecting ends, so that the first rod and the second rod move closer to each other or further away from each other, thereby driving the linkage rod to rotate.

[0008] In one possible design, the housing is further provided with a snap-fit ​​groove, and the transmission mechanism further includes a positioning post. The first rod and the second rod are rotatably connected through the positioning post. The end of the positioning post near the housing engages with the snap-fit ​​groove to restrict the relative rotation of the first rod and the second rod.

[0009] In one possible design, the housing is further provided with a sliding groove, and the transmission mechanism further includes a rotating connector, wherein the second rod and the connecting rod are rotatably connected through the rotating connector, and the end of the rotating connector near the housing slides in cooperation with the sliding groove.

[0010] In one possible design, the snap-fit ​​groove is connected to the slide groove, and the slide groove has a through portion along the extension direction of the snap-fit ​​groove, so that the positioning post can slide out along the through portion to disengage the positioning post from the snap-fit ​​groove.

[0011] In one possible design, the bottom door includes a first door and a second door. One end of the first door is rotatably connected to the linkage rod, and the other end is rotatably connected to the second door. The first door is also provided with a connecting part, and the box body is also provided with a protrusion. The first door and the box body are rotatably connected through the connecting part and the protrusion. During the process of the bottom door opening the bottom opening, the first door can rotate relative to the box body under the drive of the transmission mechanism.

[0012] In one possible design, the first door includes a first and a second obstruction that are bent relative to each other. When the bottom door closes the bottom opening, the first obstruction contacts the side wall of the housing, and the second obstruction and the second door obstruct the bottom opening.

[0013] In one possible design, the first door further includes an extension arm extending in a direction away from the second shield, one end of the extension arm being fixedly connected to the first shield and the other end being rotatably connected to the linkage rod.

[0014] In one possible design, the first door further includes a reinforcing beam disposed between the extension arm and the second shield.

[0015] In one possible design, the logistics box further includes a guide rail, the bottom door is provided with a slider, the guide rail is fixed to the box body, and the slider slides in cooperation with the guide rail.

[0016] In one possible design, the logistics box further includes at least one side door, and the box body is also provided with at least one side opening. The side door is installed on the box body and is used to open or close the side opening.

[0017] A second aspect of this application provides a drone delivery system, including a drone, a ground device, and a logistics box as described in any of the above embodiments. The drone is used to transport the logistics box to or away from the ground device. The ground device is provided with a drive mechanism, which is used to drive the transmission mechanism of the logistics box so that the transmission mechanism drives the bottom door of the logistics box to open or close the bottom opening of the box.

[0018] In one possible design, the drive mechanism includes a drive member and a shift fork. The drive member is connected to the shift fork, and the shift fork is used to engage with the positioning post of the transmission mechanism, so that the drive member can drive the shift fork to disengage the positioning post from the engagement groove on the housing, and drive the drive rod of the transmission mechanism to rotate the linkage rod to drive the bottom door to open or close the bottom opening.

[0019] In one possible design, the side of the positioning post away from the housing is conical or frustum-shaped.

[0020] In one possible design, the ground device further includes a UAV take-off and landing platform and a positioning push rod, the positioning push rod being equipped with the drive mechanism, the positioning push rod being mounted on the UAV take-off and landing platform, and the positioning push rod being used to position the UAV.

[0021] In this application, during unmanned delivery missions, when the drone transports the logistics box to the ground device, the ground device's drive mechanism can drive the transmission mechanism to open the bottom opening of the box, allowing the goods or food inside the box to be unloaded through the bottom opening. After the goods or food are unloaded, the ground device's drive mechanism can also drive the transmission mechanism to close the bottom opening, allowing new goods or food to be loaded into the box, enabling the drone to take off with the logistics box to execute the next delivery route. Since the logistics box, as described in this application, can be unloaded by the ground device's drive mechanism driving the transmission mechanism to open or close the bottom opening each time it lands on the ground, this improves the unloading efficiency of the goods or food, thereby increasing delivery efficiency and enhancing user experience. Furthermore, it eliminates the need for the logistics box to be unloaded along with the goods or food in every delivery mission, reducing the depreciation rate of the logistics box, increasing its reusability, and lowering delivery costs. In addition, goods or meals are unloaded from the bottom opening of the container, and the bottom door is a side-sliding opening mechanism, which provides high stability when opening and can prevent goods or meals from tilting during unloading, ensuring the quality of delivered goods and further improving the user experience.

[0022] In addition, since the logistics box can be used with ground equipment to unload goods or meals inside the box, there is no need to install additional motors or other drive devices on the box, which can reduce the overall weight of the logistics box and improve the reliability of drone delivery.

[0081] The accompanying drawings, which are incorporated in and form part of this specification, illustrate embodiments consistent with this application and, together with the description, serve to explain the principles of this application. Detailed Implementation

[0082] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0083] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0084] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0085] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0086] It should be noted that the directional terms such as "upper," "lower," "left," and "right" described in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0087] Currently, such as Figure 1 As shown, the drone delivery system, consisting of a drone 30, a ground device 20, and a logistics box 10, has been applied to drone delivery services. Of course, the logistics box 10 in this application can also be applied to other transportation fields, and no limitation is made here.

[0088] In this embodiment, the logistics box 10 can be installed below the drone 30 either in a fixed or detachable manner; no limitation is made here. Figure 1 In the specific embodiment shown, the logistics box 10 is fixedly installed below the drone 30 to further improve the stability of the logistics box 10 on the drone 30, prevent the logistics box 10 from falling off, being damaged or lost during the delivery task, and further improve the reliability and efficiency of drone delivery.

[0089] The first aspect of this application provides a logistics box, such as... Figures 2-5As shown, the device includes a housing 1, a transmission mechanism 2, and a bottom door 3. The housing 1 includes a bottom opening 11. The transmission mechanism 2 is installed on the housing 1. The bottom door 3 is slidably disposed on the bottom opening 11 and connected to the transmission mechanism 2. The bottom door 3 can open or close the bottom opening 11 under the drive of the transmission mechanism 2.

[0090] In this embodiment, during the unmanned delivery mission, when the drone 30 transports the logistics box 10 to the ground device 20, such as Figures 6-8 As shown, the drive mechanism 203 of the ground device 20 can drive the transmission mechanism 2 to open the bottom opening 11 of the box 1 through the bottom door 3, so that the goods or food in the box 1 can be unloaded through the bottom opening 11 at the bottom of the box 1. After the goods or food in the box 1 are unloaded, as... Figure 9 As shown, the drive mechanism 203 of the ground device 20 can also drive the transmission mechanism 2 to close the bottom opening 11 of the box 1 via the bottom door 3, so that the box 1 can be loaded with new goods or meals, so that the drone 30 can take off with the logistics box 10 to perform the next delivery route. Since each time the drone 30 lands on the ground device 20 with the logistics box 10 in this embodiment, the logistics box 10 can be unloaded by driving the transmission mechanism 2 via the drive mechanism 203 on the ground device 20 to open or close the bottom opening 11 of the box 1 via the bottom door 3, thereby improving the unloading efficiency of the goods or meals in the box 1, thereby improving the delivery efficiency of the goods or meals, improving the user experience, and eliminating the need for the logistics box 10 to be unloaded along with the goods or meals in each delivery mission, reducing the depreciation rate of the logistics box 10, increasing the reuse rate of the logistics box 10, and reducing delivery costs. In addition, the goods or meals in the container 1 are unloaded from the bottom opening 11, and the bottom door 3 is a side-sliding opening method, which has a high degree of stability when opening, which can prevent the goods or meals from tilting during unloading, ensuring the quality of the delivered goods and further improving the user experience.

[0091] In addition, since the logistics box 10 can work with the ground device 20 to unload the goods or food inside the box 1, there is no need to install a motor or other drive device on the box 1, which can reduce the overall weight of the logistics box 10 and improve the reliability of drone delivery.

[0092] Among them, such as Figures 3-5 In the specific embodiment shown, there can be two bottom doors 3 along their opening direction, forming a symmetrical structure, which further improves the opening efficiency of the bottom doors 3. Of course, the bottom doors 3 can also be set to an asymmetrical structure, or only one, depending on the specific function; there is no limitation here.

[0093] In addition, such as Figures 3-5 As shown, the transmission mechanism 2 is symmetrically arranged at both ends of the bottom door 3, so that the bottom door 3 can be opened or closed by single-sided drive or double-sided drive, as shown. Figure 1 In the specific embodiment shown, two drive mechanisms 203 are correspondingly provided on the ground device 20, that is, the bottom door 3 is opened or closed by a dual-side drive, making the bottom door 3 easier to open and the force is more stable during the opening process, avoiding jamming.

[0094] In one specific embodiment, such as Figures 3-6 As shown, the transmission mechanism 2 includes a drive rod 21 and a connecting rod 22. One end of the connecting rod 22 is connected to the drive rod 21, and the other end is connected to the bottom door 3. The drive rod 21 can drive the connecting rod 22 to rotate, so as to drive the bottom door 3 to open or close the bottom opening 11.

[0095] In this embodiment, as Figures 3-6 As shown, during the opening of the bottom door 3, the connecting rods 22 on both sides can rotate simultaneously under the drive of the drive rod 21, thereby pulling the bottom door 3 to provide a force for sliding to both sides, controlling the bottom doors 3 on both sides to slide in opposite directions at the same time, opening the bottom opening 11 of the box 1, preventing the goods or food inside the box 1 from tilting during the opening of the bottom door 3, improving the stability of the opening of the bottom door 3. This structure can also shorten the opening stroke of the bottom door 3, improve the opening efficiency of the bottom door 3, thereby improving the unloading efficiency of the logistics box 10. Moreover, this structure is simple and easy to realize the simultaneous opening of the bottom doors 3 on both sides, reducing the structural complexity of the logistics box 10.

[0096] The linkage 22 can correspond to either a symmetrical or asymmetrical structure for the bottom door 3; no restrictions are imposed here. Figures 3-5 In the specific embodiment shown, the linkage 22 is also a symmetrical structure corresponding to the ground 3, so as to improve the opening synchronization of the bottom door 3.

[0097] In one specific embodiment, such as Figures 3-6 As shown, the drive rod 21 includes a first rod 211 and a second rod 212. One end of the first rod 211 and the second rod 212 are rotatably connected. The other end of the first rod 211 is rotatably connected to the housing 1. The other end of the second rod 212 is rotatably connected to the connecting rod 22. The first rod 211 and the second rod 212 can rotate relative to each other around their connecting ends so that the first rod 211 and the second rod 212 move closer to each other or further away from each other, thereby driving the connecting rod 22 to rotate.

[0098] In this embodiment, as Figures 3-6As shown, during the opening of the bottom door 3, the first rod 211 and the second rod 212 can rotate relative to each other around their connecting ends, bringing the first rod 211 and the second rod 212 closer together. This reduces the space of the drive rod 21 in the height direction on the side wall of the box 1, thereby providing rotation space for the linkage rod 22. Since one end of the first rod 211 is rotatably connected to the side wall of the box 1, the end of the linkage rod 22 connected to the second rod 212 can move towards the first rod 211 under the drive of the second rod 212, thereby causing the linkage rod 22 to rotate and providing a force to open the bottom door 3. During the closing process of the bottom door 3, the first rod 211 and the second rod 212 can rotate relative to each other around their connecting ends, causing the first rod 211 and the second rod 212 to move away from each other. This increases the space of the drive rod 21 in the height direction on the side wall of the box 1, allowing the end of the connecting rod 22 connected to the second rod 212 to move away from the first rod 211 under the drive of the second rod 212. This causes the connecting rod 22 to rotate, providing a force to close the bottom door 3. This structure is simple, easy to implement, reliable, and easy to control, and can further reduce the manufacturing cost of the logistics box 10.

[0099] Of course, the drive rod 21 can also be other structures that can extend or retract in the height direction of the housing 1, such as a telescopic rod, etc., and there is no limitation here.

[0100] In one specific embodiment, such as Figure 6 and Figure 9 As shown, the housing 1 is also provided with a snap-fit ​​groove 13, and the transmission mechanism 2 also includes a positioning post 23. The first rod 211 and the second rod 212 are rotatably connected through the positioning post 23. The end of the positioning post 23 near the housing 1 is engaged with the snap-fit ​​groove 13 to restrict the relative rotation of the first rod 211 and the second rod 212.

[0101] In this embodiment, as Figure 6 and Figure 9 As shown, the positioning post 23 facilitates the rotational connection of the first rod 211 and the second rod 212. The positioning post 23 cooperates with the snap-fit ​​groove 13 to restrict the relative rotation of the first rod 211 and the second rod 212 during the flight of the drone 30. This prevents the bottom door 3 from being driven by the transmission mechanism 2 to open the bottom opening 11 of the box 1 during the flight of the drone 30, thus avoiding the loss of goods or food inside the box 1. This improves the structural stability of the bottom door 3 of the logistics box 10 in the closed state and enhances the reliability of drone delivery.

[0102] like Figure 6 and Figure 9In the specific embodiments shown, the locking groove 13 is eccentrically positioned, so that after the positioning post 23 engages with the locking groove 13, the first rod 211 and the second rod 212 can push the positioning post 23 to press against the side wall of the locking groove 13 in the horizontal direction under their own weight, so that the first rod 211 and the second rod 212 cannot continue to rotate. At the same time, it has a good fixing effect, so that the positioning post 23 is not easy to loosen and detach from the locking groove 13 during the flight of the drone 30. This ensures that the transmission mechanism 2 will not drive the bottom door 3 to open the bottom opening 11 of the box 1 during the flight of the drone 30. Furthermore, no other structure is needed to push the positioning post 23 to the locking groove 13, which further reduces the structural complexity of the logistics box 10 and reduces costs.

[0103] The locking groove 13 can be a semi-circular groove, square groove, elliptical groove, arc groove, or other shape that mates with the positioning post 23. Alternatively, the positioning post 23 and the locking groove 13 can be configured as an interference fit, or damping components or elastic devices can be provided in the locking groove 13 to further improve the locking and fixing effect of the positioning post 23 in the locking groove 13, and further prevent the positioning post 23 from loosening during the flight of the UAV 30, causing the first rod 211 and the second rod 212 to rotate.

[0104] like Figure 6 and Figure 9 In the specific embodiments shown, the positioning post 23 is circular on the side facing the housing 1, and the snap-fit ​​groove 13 is a semi-circular groove that mates with the positioning post 23, so that the positioning post 23 can mate with the snap-fit ​​groove 13 in any direction, thereby improving the mate efficiency between the snap-fit ​​groove 13 and the positioning post 23.

[0105] In one specific embodiment, such as Figures 6-8 As shown, the housing 1 is also provided with a slide groove 14, and the transmission mechanism 2 also includes a rotating connector 24. The second rod 212 and the connecting rod 22 are rotatably connected through the rotating connector 24, and the end of the rotating connector 24 near the housing 1 is slidably engaged with the slide groove 14.

[0106] In this embodiment, as Figures 6-8As shown, the rotating connector 24 facilitates the rotational connection between the second rod 212 and the connecting rod 22. The rotating connector 24 slides in conjunction with the slide groove 14 on the housing 1, allowing the second rod 212 to drive the connecting rod 22 to slide along the slide groove 14 at one end. This provides guidance for the movement of the drive rod 21, preventing the drive rod 21 from deviating and ensuring its smooth movement. It also ensures the synchronous rotation of the connecting rods 22 on both sides, allowing the bottom doors 3 on both sides to be opened simultaneously, improving the opening effect of the bottom doors 3. At the same time, it also limits the displacement of the drive rod 21 in the height direction of the housing 1, preventing the drive rod 21 from driving the connecting rod 22 to rotate excessively, causing damage to the bottom doors 3 due to excessive opening, or causing impact deformation of the bottom doors 3 during closing, thus improving the service life of the bottom doors 3.

[0107] In one specific embodiment, such as Figures 6-9 As shown, the snap-fit ​​groove 13 is connected to the slide groove 14, and along the extension direction of the snap-fit ​​groove 13, the slide groove 14 is provided with a through part 141, and the positioning post 23 can slide out along the through part 141 so that the positioning post 23 and the snap-fit ​​groove 13 can be disengaged.

[0108] In this embodiment, as Figures 6-9 As shown, during the opening of the bottom door 3, after the positioning post 23 and the locking groove 13 are disengaged, they can continue to slide out along the through part 141, thereby releasing the restriction on the relative rotation of the first rod 211 and the second rod 212. This allows the second rod 212 to drive the rotating connector 24 and one end of the connecting rod 22 connected to it to slide along the slide groove 14 toward the first rod 211, thus enabling the connecting rod 22 to drive the bottom door 3 to open. During the closing of the bottom door 3, the positioning post 23 can also slide into the locking groove 13 through the through part 141, achieving the locking engagement between the positioning post 23 and the locking groove 13. This structure is simple, easy to implement, and convenient to operate and control, improving the control efficiency of the bottom door 3.

[0109] In one specific embodiment, such as Figures 6-9 As shown, the bottom door 3 includes a first door 31 and a second door 32. One end of the first door 31 is rotatably connected to the connecting rod 22, and the other end is rotatably connected to the second door 32. The first door 31 is also provided with a connecting part 313a, and the box body 1 is also provided with a protrusion 15. The first door 31 and the box body 1 are rotatably connected through the connecting part 313a and the protrusion 15. During the process of opening the bottom opening 11 of the bottom door 3, the first door 31 can rotate relative to the box body 1 under the drive of the transmission mechanism 2.

[0110] In this embodiment, as Figures 6-9As shown, during the opening of the bottom door 3, the rotation of the linkage 22 can cause the first door 31 to rotate around the connecting part 313a in a direction away from the box body 1, thereby driving the second door 32 to slide open the bottom opening 11, realizing the unloading of goods or food inside the box body 1. Furthermore, since the first door 31 and the second door 32 are rotatably connected, the first door 31 can continue to rotate relative to the second door 32 under the action of the linkage 22 after disengaging from the bottom opening 11, thus reducing the space occupied by the first door 31 in the horizontal direction and preventing interference between the bottom door 3 and the components on the bottom surface device 20 during the opening process, ensuring the opening effect of the bottom door 3. In addition, the first door 31 and the box body 1 are rotatably connected through the connecting part 313a and the protrusion 15, providing support for the bottom door 3 and preventing the linkage 22 from being unable to rotate due to the gravity of the bottom door 3 during the opening process, ensuring the reliable operation of the transmission mechanism 2.

[0111] Of course, along the opening direction of the bottom door 3, the bottom door 3 may also include a third door, a fourth door, a fifth door, etc., which are connected by multiple plates in sequence and are not limited here.

[0112] In one specific embodiment, such as Figure 6 and Figure 9 As shown, the first door 31 includes a first blocking part 311 and a second blocking part 312 that are bent relative to each other. When the bottom door 3 closes the bottom opening 11, the first blocking part 311 contacts the side wall of the box 1, and the second blocking part 312 and the second door 32 block the bottom opening 11.

[0113] In this embodiment, as Figure 6 and Figure 9 As shown, the second shielding part 312 and the second door 32 shield the bottom opening 11, ensuring the bottom of the box 1 is sealed after the bottom door 3 is closed, thus enabling the box 1 to hold goods or food. When the bottom door 3 closes the bottom opening 11, the first shielding part 311 contacts the side wall of the box 1, preventing the bottom door 3 from closing too quickly and avoiding the second door 32 from colliding and deforming or being damaged during the closing process. This improves the service life of the bottom door 3 and also prevents the first door 31 and the second door 32 from being squeezed when closing, which could cause the second shielding part 312 and the second door 32 to be out of sync, resulting in a bulge or depression at the bottom of the box 1 and making the goods or food unstable. This ensures the flatness of the bottom of the box 1 after the bottom door 3 is closed, guaranteeing the stability of the goods or food during delivery.

[0114] In one specific embodiment, such as Figures 6-9 As shown, the first door 31 also includes an extension arm 313 extending in a direction away from the second blocking part 312. One end of the extension arm 313 is fixedly connected to the first blocking part 311, and the other end is rotatably connected to the linkage rod 22.

[0115] In this embodiment, as Figures 6-9 As shown, the extension arm 313 ensures that the bottom door 3 can be connected to the linkage rod 22 while reducing the height of the first blocking part 311. This avoids the side opening 12 of the box 1 being too small due to the first blocking part 311 being too high. It also ensures the operating space of the transmission mechanism 2, ensuring the reliable operation of the transmission mechanism 2. Furthermore, it reduces the length of the linkage rod 22, shortens the transmission path, improves the transmission efficiency of the transmission mechanism 2, further simplifies the transmission mechanism 2, reduces the structural complexity of the transmission mechanism 2, and makes it easier to control the bottom door 3.

[0116] Among them, such as Figures 6-9 In the specific embodiment shown, the end of the extension arm 313 connected to the connecting rod 22 can be tilted towards one side of the connecting rod 22, thereby further shortening the length of the connecting rod 22, reducing the space occupied by the transmission mechanism 2, avoiding interference damage between the connecting rod 22 and external objects, and improving the reliability of the transmission mechanism 2.

[0117] In one specific embodiment, such as Figure 6 As shown, the first door 31 also includes a reinforcing beam 314, which is disposed between the extension arm 313 and the second shielding part 312.

[0118] In this embodiment, as Figure 6 As shown, the reinforcing beam 314 can be supported between the first shielding part 311 and the second shielding part 312, preventing the angle between the first shielding part 311 and the second shielding part 312 from changing, which would cause the bottom door 3 to fail to close properly, thus improving the structural stability of the first door 31 and ensuring the reliable closing of the bottom door 3.

[0119] Among them, the reinforcing beam 314 can be set with 1, 2, or 3 beams, or it can be set as a reinforced version; there are no restrictions here. For example... Figure 6 In the specific embodiment shown, the reinforcing beam 314 is a single beam, which can ensure the structural stability of the first door 31 while reducing the weight of the first door 31, thereby reducing the weight of the logistics box 10, so as to facilitate the flight of the drone 30.

[0120] In one specific embodiment, such as Figures 6-9 As shown, the logistics box 10 also includes a guide rail 4, and the bottom door 3 is equipped with a slider 33. The guide rail 4 is fixed to the box body 1, and the slider 33 slides in cooperation with the guide rail 4.

[0121] In this embodiment, as Figures 6-9As shown, the bottom door 3 and the housing 1 are slidably engaged by the slider 33 and the guide rail 4, which can reduce the sliding friction between the bottom door 3 and the housing 1, allowing the bottom door 3 to slide with less friction through the slider 33 and the guide rail 4. This makes it less likely for the bottom door 3 to get stuck during the sliding process, making it easier to control the bottom door 3 to open or close, reducing the difficulty of controlling the bottom door 3 by the transmission mechanism 2, and improving the control efficiency of the transmission mechanism 2 on the bottom door 3.

[0122] The slider 33 and the guide rail 4 can be made of low-friction materials, and the slider 33 can also be a bearing structure or other structure that can slide with the guide rail 4. There are no restrictions on this.

[0123] Of course, the bottom door 3 and the box body 1 can also achieve sliding engagement in other ways. For example, one of the box body 1 and the bottom door 3 is provided with a groove, and the other is provided with a protrusion that engages with the groove. The box body 1 and the bottom door 3 can slide together through the groove and the protrusion, etc. There are no restrictions here.

[0124] In one specific embodiment, such as Figure 9 As shown, the logistics box 10 also includes at least one side door 5, and the box body 1 is also provided with at least one side opening 12. The side door 5 is installed on the box body 1 and is used to open or close the side opening 12.

[0125] In this embodiment, as Figure 9 As shown, after the goods or meals in the container 1 are unloaded, the bottom door 3 is closed, and the side door 5 can be opened. The goods or meals to be delivered can be put into the container 1 through the side opening 12 of the container 1, so that the container 1 can be loaded with new goods or meals, so that the drone 30 can take off with the logistics line 10 to perform the next delivery route.

[0126] Among them, such as Figure 9 In the specific embodiment shown, the housing 1 has a side opening 12 and a side door 5, which can further reduce the structural complexity of the housing 1 and reduce costs. Of course, the housing 1 can also be provided with side openings and side doors in multiple directions, which is not limited here.

[0127] In addition, the side door 5 can open in various ways, such as opening to the left or right, or opening to the top or bottom, etc., without any restrictions.

[0128] In addition, in other embodiments, the side door 5 may also be in the form of a drawer, etc., and there is no limitation here.

[0129] This application also provides a drone delivery system, such as... Figure 1As shown, the system includes a drone 30, a ground device 20, and a logistics box 10 according to any of the above embodiments. The drone 30 is used to transport the logistics box 10 to or from the ground device 20. The ground device 20 is equipped with a drive mechanism 203, which drives the transmission mechanism 2 of the logistics box 10 to open or close the bottom opening 11 of the box body 1 via the bottom door 3. Since the logistics box 10 has the aforementioned technical effects, the drone delivery system including the logistics box 10 should also have corresponding technical effects, which will not be elaborated further here.

[0130] In one specific embodiment, such as Figures 10-12 As shown, the drive mechanism 203 includes a drive member 203a and a shift fork 203b. The drive member 203a is connected to the shift fork 203b. The shift fork 203b is used to engage with the positioning post 23 of the transmission mechanism 2, so that the drive member 203a can drive the shift fork 203b, thereby disengaging the positioning post 23 from the engagement groove 13 on the housing 1, and driving the drive rod 21 of the transmission mechanism 2 to rotate the connecting rod 22, thereby driving the bottom door 3 to open or close the bottom opening 11.

[0131] In this embodiment, as Figures 10-12 As shown, the structure is simple, low-cost and easy to implement. The driving component 203a can provide power for the rotation of the shift fork 203b. The shift fork 203b can cooperate with the positioning column 23, so that the driving component 203a can control the movement of the positioning column 23 through the shift fork 203b, thereby realizing the control of the bottom door 3.

[0132] The drive unit 203a can be an existing servo motor, or it can be obtained by modifying the servo motor, or it can be other power sources, without any restrictions.

[0133] In addition, such as Figures 10-12 As shown, the shift fork 203b has a fork-shaped structure with a groove in the middle, so that it can provide sufficient space for the positioning column 23 to move during the rotation of the control positioning column 23, ensuring the reliable operation of the transmission mechanism 2, and avoiding the positioning column 23 and shift fork 203b from jamming, which would cause the linkage rod 22 to rotate insufficiently and fail to drive the bottom door 3 to open normally, affecting the unloading of goods or food in the box 1.

[0134] In one specific embodiment, such as Figure 13 As shown, the side of the positioning post 23 away from the housing 1 is conical or frustum-shaped.

[0135] In this embodiment, as Figure 13As shown, when the side of the positioning post 23 away from the housing 1 is conical or frustoconical, the volume of the side of the positioning post 23 away from the housing 1 can be reduced, thus facilitating the positioning of the shift fork 203b. At the same time, the side of the positioning post 23 of this structure is an inclined surface, which can provide guidance for the insertion of the shift fork 203b, making it easier for the shift fork 203b to be inserted and engaged, reducing the difficulty of engaging the shift fork 203b and the positioning post 23, and improving the engagement efficiency.

[0136] Of course, the side of the positioning post 23 away from the housing 1 can also be other shapes, such as cylindrical or square, and there are no restrictions here.

[0137] In one specific embodiment, such as Figure 14 As shown, the ground device 20 also includes a UAV take-off and landing platform 201 and a positioning push rod 202. The positioning push rod 202 is equipped with a drive mechanism 203. The positioning push rod 202 is installed on the UAV take-off and landing platform 201 and is used to position the UAV 30.

[0138] In this embodiment, as Figure 14 As shown, when the drone 30 transports the logistics box 10 to the ground device 20, the drone 30 lands on the drone take-off and landing platform 201. The positioning push rod 202 can move to position the drone in the correct unloading position so that the drive mechanism 203 and the transmission mechanism 2 can cooperate, thereby improving the cooperation efficiency of the positioning column 23 of the drive mechanism 203 and the transmission mechanism 2, and thus improving the unloading efficiency.

[0139] Among them, such as Figure 14 As shown, the positioning push rod includes a first push rod 202a and a second push rod 202b that are set approximately vertically. The first push rod 202a and the second push rod 202b can push the drone 30 to the correct unloading position by pushing the footrest 301 of the drone 30, thereby achieving the positioning of the drone 30.

[0140] In addition, the specific position and number of the drive mechanism 203 on the positioning push rod 202 can be set according to the specific structure of the logistics box 10, and there is no limitation here.

[0141] like Figure 15 As shown, before the drone 30, carrying the logistics box 10, is transported to the ground device 20, the positioning push rods 202 are in a state of being far apart from each other, with a large space in the middle, which facilitates the landing of the drone 30.

[0142] The specific process of a drone delivery system: such as Figure 16 As shown, the drone 30, carrying the logistics box 10, lands in the larger space area between the positioning push rods 202. Figure 17 As shown, the first push rod 202a moves inward, aligning the drone 30 by pushing the landing gear 301 of the drone 30. Figure 18As shown, the second push rod 202b moves further inward, pushing the drone 30's legs 301 to the target position, thus positioning the drone 30 correctly for unloading goods or meals from the logistics box 10. Simultaneously, the fork 203b of the drive mechanism 203 engages with the positioning post 23 of the transmission mechanism 2 on the logistics box 10. Figure 19 As shown, at this time, the bottom door 3 of the logistics box 10 can be driven by the drive component 203a to rotate the fork 203b, causing the positioning post 23 to disengage from the locking groove 13, thereby opening the bottom door 3. This allows the goods or food inside the box 1 to be unloaded onto the drone landing platform 201 through the bottom opening 11 of the box 1, thus achieving the unloading of goods or food. Figure 20 As shown, after continuing to operate the drive mechanism 203 to close the bottom door 3, open the side door 5 and load the next batch of goods or meals to be delivered into the container 1 through the side opening 12. After closing the side door 5, as shown... Figure 1 As shown, the positioning push rods 202 move away from each other to release the positioning control of the drone 30, and the drone 30, carrying the logistics box 10, takes off to execute the next delivery route.

[0143] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
