Detailed Implementation

[0035] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0036] It should be noted that all actions involving the acquisition of signals, information, or data in this disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the location is situated, and with authorization from the owner of the relevant device.

[0037] In this disclosure, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" generally refer to the normal placement of the transport bag, the item connection mechanism, and the drone mounting mechanism provided in this disclosure, as well as their normal installation. "Inner" and "outer" refer to the inner and outer contours of the corresponding components. The terms "first," "second," etc., are used to distinguish different components and do not imply sequentiality or importance. Furthermore, in the following description, when referring to the accompanying drawings, unless otherwise explained, the same reference numerals in different drawings denote the same or similar elements.

[0038] In related technologies, during the process of transferring the handle of a transport bag from one lifting mechanism to another, the different lifting mechanisms acting on the narrow part of the handle can easily cause interference, resulting in incomplete lifting and failure to ensure a smooth transfer.

[0039] Assuming the following delivery scenario exists, as shown in Figure 10, a transport bag 1 containing items or goods is placed in different compartments 2 of a container. Each compartment 2 is equipped with a compartment mounting mechanism 21, and the handle 11 of the transport bag 1 is hung on the compartment mounting mechanism 21. A movable robotic arm is installed inside the container, as shown in Figures 16 to 20. The end of the robotic arm is equipped with a connecting mechanism 3. The robotic arm moves to a designated position and places the transport bag 1 in the corresponding compartment 2 onto the connecting mechanism 3. The robotic arm drives the connecting mechanism 3 and the transport bag 1 to the top opening of the container. An incoming drone lands at a designated position (e.g., the landing platform on top of the container) and connects with the connecting mechanism 3. The transport bag 1 located on the connecting mechanism 3 is transferred to the receiving end of the drone and the transport bag 1 is mounted on the drone. The drone carries the transport bag 1 and flies to the delivery location, and automatically releases the transport bag 1 at a designated location at the delivery location or transfers it to the container at the delivery location, completing the automatic drone delivery process. Conversely, the drone carrying the transport bag 1 can also transfer the goods to the connecting mechanism 3 inside the container. The robotic arm drives the connecting mechanism 3 to the designated compartment 2 and transfers the transport bag 1 to the compartment mounting mechanism 21 of the compartment 2, realizing the automatic transfer of the transport bag 1 between containers in different buildings and between merchants and users, achieving unmanned delivery, improving delivery efficiency and user experience.

[0040] Based on the above delivery scenarios, improvements are made to the transport bag 1, the container, and the drone. Separate compartment mounting mechanisms 21, item transfer mechanisms 3, and drone mounting mechanisms 4 are designed. Corresponding designs are made for the transport bag 1 and its handle 11. A detailed description will follow with specific embodiments. Of course, the compartment mounting mechanism 21, item transfer mechanism 3, and drone mounting mechanism 4 are not limited to the above delivery scenarios. Any structure capable of transferring, hoisting, locking, and releasing the transport bag 1 falls within the scope of this disclosure.

[0041] Regarding transport bags, as shown in Figures 1 to 5, this disclosure provides a transport bag 1, which includes a bag body 10 and a handle 11 disposed on the bag body 10. The transport bag 1 is not limited to drone delivery scenarios, but can also be used in scenarios such as daily hand carrying by users, delivery by food delivery personnel, and supermarket sales. The transport bag 1 can be a packaging bag for various goods, a takeaway bag, a food bag, etc. The following will take the design of a food bag in the drone delivery scenario as an example for detailed introduction.

[0042] In this disclosure, as shown in Figures 2 and 5, the bag body 10 includes a bag body 101 and a cover 102. A handle 11 is connected to the cover 102, which is used to close the top opening of the bag body 101. The cover 102 has a polygonal planar structure. In the transport bag 1 provided in this disclosure, the sealing positions of the cover 102 and the bag body 101 are designed as planes, which can increase the internal storage space. The increased internal space can accommodate more irregularly shaped goods, allowing for the loading of more goods, thereby increasing the loading capacity of a single transport and improving space utilization.

[0043] This disclosure provides two types of transport bags 1, namely the first type shown in Figures 1 to 3 and the second type shown in Figures 4 and 5. In the second type of transport bag, the handle 11 can be directly fixed to the cover 102, which can be fixed by adhesive, double-sided adhesive or heat pressing. An opening and closing element 103 is provided at the position where the cover 102 and the bag body 101 meet. One side of the cover 102 is fixedly connected to the opening edge of the bag body 101, and the other sides of the cover 102 are provided with opening and closing elements 103. The bag body 10 can be made of non-woven fabric, and the opening and closing element 103 can be a zipper sewn to the corresponding edge. In other embodiments, the opening and closing element 103 can also be Velcro, hook and loop fastener, etc., which makes operation simple, makes it more convenient to take out and put in items, and improves loading efficiency.

[0044] In the first type of transport bag, as shown in Figures 2 and 3, the cover 102 includes a first open edge 1021 and a second open edge 1022. The first open edge 1021 and the second open edge 1022 are respectively connected to the opening edge of the bag body 101, and the first open edge 1021 and the second open edge 1022 are arranged opposite to each other. The first open edge 1021 is provided with an opening 1023, and the handle 11 is fixedly connected to the second open edge 1022. The opening 1023 is used to allow the handle 11 to extend when the first open edge 1021 overlaps the second open edge 1022. The edges of the first open edge 1021 and / or the second open edge 1022 are provided with downwardly folded sealing edges 1024.

[0045] As shown in Figures 2 and 5, the handle 11 includes a fixing part 114 and a main body 110 disposed on the fixing part 114. The fixing part 114 is fixedly connected to two fixing arms 1111, which are perpendicular to the plane of the fixing part 114. An opening is provided on the second open side 1022. The main body 110 passes through the opening and is fixed to the second open side 1022 by the stop of the fixing part 114. In other embodiments, the solid part 114 can also be directly fixed by heat pressing or by gluing to the second open side 1022. The main body 110 of the handle 11 extends out after passing through the opening on the second open side 1022 and the opening 1023 on the first open side 1021 in sequence. At the position of the handle 11, it is designed with a multi-layer structure to strengthen the connection strength at the position of the handle 11 and prevent the handle 11 from coming off and affecting the lifting.

[0046] In addition, the fixing part 114 can stop on the inner surface of the second open edge 1022, increasing the contact area with the second open edge 1022. In this disclosure, the projection of the connecting arm 1112 on the plane where the fixing part 114 is located coincides with the axis of symmetry of the fixing part 114. The fixing parts 114 on both sides of the connecting arm 1112 are symmetrically arranged to ensure that the handle 11 is balanced on both sides during hoisting, and there will be no uneven hoisting, thus avoiding damage to the transport bag 1. The distance from the axis of symmetry of the fixing part 114 to the edge of the fixing part 114 is 15 to 30 centimeters. The handle 11 adopts a widened design. In the width direction, the fixing parts 114 are provided on both sides of the main body 110, and the dimension of the fixing parts 114 in the width direction is widened. As shown in Figure 2, the fixing part 114 can basically cover the entire surface of the cover 102, stably fixing the handle 11 to the second open edge 1022. Especially in embodiments where the bag body 10 is made of soft material, the fixing part 114 can ensure the connection reliability at the position of the handle 11, and at the same time maintain the shape of the transport bag 1 when hoisting it. In this disclosure, as shown in Figure 6, weight reduction holes 1140 of the fixing part 114 are respectively provided on both sides of the axis of symmetry. While ensuring the overall strength of the handle 11, the weight of the handle 11 can be reduced, which conforms to the design principle of lightweighting.

[0047] The transport bag 1 in the embodiments shown in Figures 1 to 3 can be made of a material similar to corrugated cardboard or plastic. The side walls of the bag body 10 have creases, allowing it to be folded after use to reduce space occupation. Furthermore, after the first open edge 1021 overlaps with the second open edge 1022, to prevent the first open edge 1021 from lifting up, Velcro or double-sided tape can be designed on the sealing edge 1024 of the first open edge 1021. This allows it to be folded over and fixed to the side wall of the bag body 101 when the first open edge 1021 overlaps with the second open edge 1022, ensuring a tight seal and better protection for the goods inside the bag.

[0048] For the container, two main improvements were made: first, a compartment hanging mechanism 21 was added to the compartment 2 of the container; second, the item transfer mechanism 3 located at the end of the robotic arm was improved. Both of these improvements are coordinated with the handle 11 of the transport bag 1. The following will introduce the structure of the item transfer mechanism 3 and the handle 11 and their coordination method, as well as the structure of the compartment hanging mechanism 21 and the handle 11 and their coordination method, in conjunction with specific embodiments, so as to successfully complete the transfer action.

[0049] As shown in Figures 6 to 8, this disclosure provides a handle 11, which has a first lifting position 111 and a second lifting position 112 for cooperating with different lifting mechanisms and a positioning hole 113. The first lifting position 111 and the second lifting position 112 can be provided on the main body 110 of the handle 11. The main body 110 of the handle 11 includes two fixed arms 1111 and a connecting arm 1112 connecting the two fixed arms 1111. The two fixed arms 1111 and the connecting arm 1112 together form a lifting hole 1110. The first lifting position 111 is formed at the position where the fixed arms 1111 and the connecting arm 1112 are connected. The two ends of the connecting arm 1112 are provided with outwardly extending extension arms 1113. The extension arms 1113 are arranged at an angle to the fixed arms 1112 and form the second lifting position 112. The positioning hole 113 is used to identify at least one of the first lifting position 111 and the second lifting position 112.

[0050] The different lifting mechanisms here can be any suitable lifting mechanism. According to the position of the positioning hole 113, as shown in Figure 21, the first lifting position 111 can be used to cooperate with the item receiving mechanism 3, as shown in Figures 12 and 27. The second lifting position 112 can be used to cooperate with the grid mounting mechanism 21 or the drone mounting mechanism 4. The second lifting position 112 is located outside the lifting hole 1110. During the transfer of the transport bag 1, different lifting mechanisms act on different parts of the handle 11 to avoid interference and ensure smooth transfer. At the same time, different lifting mechanisms cooperate with the corresponding lifting positions to ensure that the transport bag 1 will not fall off during the lifting process, which is stable and reliable, ensures delivery efficiency, and improves user experience.

[0051] The second lifting position 112 can cooperate with the compartment hanging mechanism 21 of the compartment 2. In this disclosure, as shown in Figures 9 to 12, the container has multiple compartments 2 for storing goods. Each compartment 2 is provided with a compartment hanging mechanism 21. As shown in Figures 13 to 15, the compartment hanging mechanism 21 has a main body 210, a connecting part 211 and a hanging part 212 provided on two opposite sides of the main body 210, and a first stop part 213. The connecting part 211 is used to fix it to the inner wall of the compartment 2. The hanging part 212 and the first stop part 213 are arranged at an angle to each other to form a lifting space. Specifically, the extension arm 1113 of the handle 11 is placed between the hanging part 212 and the first stop part 213. The first stop part 213 and the hanging part 212, which are at an angle to each other, can stop and limit the extension arm 1113 in the front and rear directions. The connecting part 211 and the hanging part 212 are respectively provided on the front and rear sides of the main body 210 and are arranged at intervals in the height direction. The connecting part 211 can be fixed on the top wall of the compartment 21. The hanging part 212 and the first stop part 213 arranged at an angle to each other form a hook. The extension arms 1113 on both sides of the handle 11 can be precisely positioned at the hook to stably hang the transport bag 1 on the compartment hanging mechanism 21, waiting for the user to take the transport bag 1 away.

[0052] Furthermore, in another exemplary embodiment of this disclosure, as shown in Figures 14 and 15, a second stop 214 protrudes from the hanging portion 212, forming a hanging gap 2120 between the second stop 214 and the first stop 213. The second stop 214 and the first stop 213 each have a guide surface inclined toward the hanging gap 2120. Compared to the embodiment shown in Figure 13, this embodiment is more compatible with the extension arm 1113, stably confining the extension arm 1113 within the hanging gap 2120. Simultaneously, the inclined arrangement of the guide surfaces of the first stop 213 and the second stop 214 provides guidance when a certain offset occurs, ensuring that the extension arm 1113 can smoothly enter the hanging gap 2120.

[0053] Furthermore, in this disclosure, there are two hanging parts 212, respectively located on the left and right sides of the main body 210, as shown in Figure 12. A clearance space is formed between the two hanging parts 212 to accommodate the handle 11. The distance between the two hanging parts 212 can be designed according to the distance between the two fixed arms 1112 of the handle 11. In addition, the item transfer mechanism 3, typically located at the end of the robotic arm, transfers the transport bag 1 to the compartment mounting mechanism 21 of the compartment 2. Correspondingly, a notch 22 is provided on the top wall of the compartment 2 to allow passage of the item transfer mechanism 3, ensuring smooth transfer of the transport bag 1 between the item transfer mechanism 3 and the compartment mounting mechanism 21. Specifically, in this embodiment, the main body 210 includes a main body 2101 and bases 2102 located on both sides of the main body 2101. The main body 210 is designed as a U-shaped structure with the opening facing downward. The bases 2102 on both sides are respectively provided with hanging parts 212 and first stop parts 213. The main body 2101, the bases 2102 on both sides and the hanging parts 212 on both sides together form an avoidance space.

[0054] The first hoisting position 111 is designed based on the structure of the item receiving mechanism 3. Accordingly, as shown in Figures 16 to 20, this disclosure provides two different item receiving mechanisms 3. The item receiving mechanism 3 can realize the receiving action of any item. For example, the "item" here can be the handle 11 of the transport bag 1 mentioned above. The following will take the transport bag 1 with handle 11 provided in this disclosure as an example for detailed description.

[0055] In this disclosure, the item receiving mechanism 3 includes a base 31 and two parallel lifting rods 32 mounted on the base 31. The two lifting rods 32 can move closer to or further away from each other. The first end of each lifting rod 32 is installed inside the base 31, and the second end is used to clamp items. The base 31 is provided with a power component 34 for driving the lifting rods 32 and a transmission component 35 disposed between the power component 34 and the lifting rods 32. The power component 34 drives the two lifting rods 32 to move synchronously, moving closer to or further away from each other, through the transmission component 35. By controlling the power component 34, the movement of the two lifting rods 32 can be automatically controlled. The two lifting rods 32 share the same power component and move synchronously, which saves space and makes the structure more compact. Of course, the two lifting rods 32 can also be driven separately, both of which fall within the protection scope of this disclosure.

[0056] In this disclosure, a first lifting position 111 is formed at the position where the fixed arm 1111 and the connecting arm 1112 of the handle 11 are connected. The first lifting position 111 has a concave section 1101 and an open section 1102. A gradually expanding section 1103 is provided at the position of the connecting arm 1112 near the open section 1102. The width of the gradually expanding section 1103 gradually decreases in the direction away from the open section 1102. The concave section 1101 is used to circumferentially limit the lifting mechanism. The lifting mechanism can exit the handle 11 from the open section 1102 and the gradually expanding section 1103. The lifting mechanism that cooperates with the first lifting position 111 can be rod-shaped. The lifting mechanism extends into the lifting hole 1110 and cooperates with the concave section 1101 to lock the handle 11 with the lifting mechanism, stably suspending the transport bag 1 on the lifting mechanism and ensuring that it will not fall during the lifting process. After being suspended to the designated position, the lifting mechanism can easily detach from the opening section 1102 and the gradually widening section 1103 and remove the handle 11. The transport bag 1 can be easily removed from the lifting mechanism, which not only ensures the stability during the lifting process, but also does not affect the subsequent transfer process of the transport bag 1. The design of the gradually widening section 1103 is related to the item receiving mechanism 3 with hook-shaped part 323 described below. Increasing the space at the position of the opening section 1102 can ensure that the hook-shaped part 323 can be smoothly withdrawn from the first lifting position 111. In this disclosure, the portion of the connecting arm 1112 located between the two gradually widening sections 1103 is thinned at the top surface of the lifting hole 1110 (thickness reduction), which is also a design to facilitate the removal of the hook-shaped part 323 from the handle 11.

[0057] In the article receiving mechanism 3 shown in Figures 16 to 18, the end of the lifting rod 32 away from the base 31 is provided with a first clamping position 301 and a second clamping position 302. The end of the lifting rod 32 is provided with a fixed block 321 and an axially movable block 322. The article can be clamped in the gap between the fixed block 321 and the movable block 322 to form the first clamping position 301. The opposing surfaces of the two fixed blocks 321 are planes. The two lifting rods 32 are close to each other, and the article can be clamped between the clamping planes 3210 of the two fixed blocks 321 to form the second clamping position 302.

[0058] Regarding the first clamping position 301, the connecting arm 1112 of the handle 11 can be clamped within the gap between the fixed block 321 and the movable block 322, thereby achieving axial limiting of the handle 11. By adjusting the axial position of the movable block 322, handles 11 of different specifications can be fixed. The size of the gap can be designed according to the wall thickness of the main body 110 of the handle 11. When the movable block 322 moves toward the fixed block 321, the handle 11 can be clamped. When the movable block 322 moves away from the fixed block 321, the handle 11 can be unlocked. By setting the movable block 322 and the fixed block 321, the handle 11 can be stably fixed at the designated position of the lifting rod 32 without axial shaking. In conjunction with the concave section 1101, it ensures the stability and reliability of the lifting of the transport bag 1 after connection.

[0059] The axial position of the movable block 322 can be adjusted in various ways, such as by threading it onto the lifting rod 32. In this disclosure, a stop is provided on the side of the movable block 322 away from the fixed block 321 on the lifting rod 32, and an elastic element 324 is provided between the stop and the movable block 322. When unlocking is required, the movable block 322 moves away from the fixed block 321, compressing the elastic element 324 and increasing the gap. When locking is required, under the restoring force of the elastic element 324, the movable block 322 automatically moves towards the fixed block 321 to perform a clamping action.

[0060] Regarding the second clamping position 302, the second clamping position 302 can be used to clamp the opposite side wall of the bag body 10, and can also realize the clamping operation of items. For example, the position of the transport bag 1 in the compartment can be adjusted, and the transport bag 1 can be hung on the compartment hanging mechanism 21, which is equivalent to adding a clamping function. Similarly, by adjusting the distance between the two lifting rods 32, items of different shapes and sizes can be clamped.

[0061] When performing clamping operations via the second clamping position 302, to avoid interference from the movable block 322, in this embodiment, the distance between the opposite sides of the two movable blocks 322 is greater than the distance between the clamping planes 3210 of the two fixed blocks 321. Alternatively, in the clamping direction of the second clamping position 302, the thickness of the movable block 322 is not greater than the thickness of the fixed block 321. By designing the form of the movable block 322, when the fixed block 321 performs the clamping action, the movable block 322 will not interfere with the item to be clamped, thus not affecting the clamping action.

[0062] In this embodiment, the fixing block 321 can be a flat block structure, and the top surface of the fixing block 321 is provided with a first inclined surface 3211 that is inclined toward the first clamping position 301. When the robotic arm drives the item receiving mechanism 3 to move and extend into the lifting hole 1110 of the handle 11, when the robotic arm extends forward too far, even if the handle 11 is located at the position of the guide inclined surface 3211, it can automatically slide into the gap between the fixing block 321 and the movable block 322 along the guide inclined surface 3211.

[0063] In this disclosure, the top of the movable block 322 is higher than the top vertex of the fixed block 321. The top of the movable block 322 being higher than the top vertex of the fixed block 321 can limit the handle 11 clamped between the two, and when the lifting rod 32 extends forward into the lifting hole 1110 of the handle 11, the movable block 322 can act on one side of the main body 110 to stop it, and directly achieve locking after the lifting rod 32 moves into place.

[0064] In this embodiment, as shown in FIG16, the clamping plane 3210 is provided with texture, which can increase the friction between the fixing block 321 and the object to be clamped, and ensure the stability of clamping.

[0065] In an exemplary embodiment of this disclosure, as shown in FIG18, the transmission member 35 includes a movable seat 353 connected to the output shaft of the power member 34 and a multi-link mechanism 354 connecting the movable seat 353 and the end of the lifting rod 32. A multi-link mechanism 354 is provided between each lifting rod 32 and the movable seat 353. The power member 34 transmits power sequentially to the movable seat 353 and the multi-link mechanism 354 to convert it into movement of the lifting rod 32. Specifically, in this embodiment, the movable seat 353 is connected to the output shaft of the power member 34. The movable seat 353 includes a nut seat 3531 and hinged rods 3532 rotatably connected to both sides of the nut seat 3531. The multi-link mechanism 354 is a four-bar linkage that is hinged sequentially. The first end of the four-bar linkage is rotatably connected to the hinged rods 3532, and the tail end is connected to the seat body 31. The end of the lifting rod 32 near the seat body 31 is connected to the hinge point of two of the linkages. The circumferential rotation of the power component 34 can be converted into the axial movement of the nut seat 3531, which in turn drives the hinge rod 3532 and the four-bar linkage to rotate, thereby converting the two lifting rods 32 into moving closer or further apart. The transmission component 35 is not limited to the multi-bar linkage shown in the above embodiments, but can also be a gear and rack, a linear module, a chain mechanism, etc.

[0066] As shown in Figure 16, the item receiving mechanism 3 also includes a camera module 38 mounted on the base 31. The camera module 38 is used to acquire the position information of the item to be clamped. As shown in Figure 8, the handle 11 is provided with positioning holes 113 for identifying the first lifting position 111 and the second lifting position 112. The positioning hole 113 is located on the handle 11 near the first lifting position 111. The base 31 of the item receiving mechanism 3 can be detachably connected to the robotic arm by fasteners. The robotic arm can move to drive the item receiving mechanism 3 to move. The camera module 38 acquires the position information of the positioning hole 113 on the handle 11 and transmits this position information to the robotic arm, thereby controlling the movement of the robotic arm and adjusting the relative position of the item receiving mechanism 3 and the handle 11 to ensure that the lifting rod 32 can be smoothly inserted into the lifting hole 1110, thereby successfully completing the receiving action. The number of positioning holes 113 can be multiple, and this disclosure does not limit this.

[0067] In the item connection mechanism 3 shown in Figures 19 and 20, the item connection mechanism includes a base 31 and two parallel lifting rods 32 mounted on the base 31. The two lifting rods 32 can move closer to or further away from each other. The driving method for moving the two lifting rods 32 closer to or further away from each other can be the same as in the above embodiment. The difference between the two item connection mechanisms 3 lies in the lifting rods 32; other identical structures will not be described again here. In this embodiment, as shown in Figure 19, the end of the lifting rod 32 away from the base 31 is provided with a hook-shaped part 323. The hook-shaped part 323 is used to pass through the lifting structure on the item and limit the lifting structure to the bend of the hook-shaped part 323.

[0068] When designing the item transfer mechanism 3, the main consideration is to receive the transport bag 1 hanging on the grid mounting mechanism 21 or the drone mounting mechanism 4 and complete the transfer action. The end of the lifting rod 32 is designed with a hook-shaped part 323. When the lifting rod 32 extends into the lifting hole 1110 of the handle 11 and is adjusted to the position of the first lifting position 111, it has an effect similar to lifting the handle 11. The handle 11 can smoothly enter the bend along the slope of the hook-shaped part 323, thereby realizing the lifting of the transport bag 1, accurately completing the transfer action, which is simple and convenient to operate and improves the transfer efficiency.

[0069] The hook-shaped portion 323 can be formed in various ways. In an exemplary embodiment of this disclosure, as shown in FIG20, the hook-shaped portion 323 has a first inclined segment 3231 and a second inclined segment 3232 forming a first included angle with each other. The opening of the first included angle is arranged upward to limit the lifting structure at the apex of the first included angle. In the design, the first included angle cannot be too small, otherwise the second inclined segment 3232 will stop when the lifting rod 32 extends into the lifting hole 1110. Of course, the first included angle cannot be too large either, otherwise the limiting effect in the front-back direction will be insufficient, causing the handle 11 to sway at the position of the hook-shaped portion 323. In this disclosure, the first included angle is designed taking into account both of the above two points. Furthermore, as shown in FIG20, in this disclosure, the distance D between the two mutually distant ends of the first inclined segment 3231 and the second inclined segment 3232 is 25-30mm, preferably 27mm. This ensures that the lifting rod 32 can be smoothly inserted into the concave segment 1101 of the lifting hole 1110, stably suspending the handle 11 at the position of the hook-shaped part 323, while also ensuring that it can be smoothly withdrawn from the lifting hole 1110 to complete the transfer action.

[0070] Furthermore, in this disclosure, the lifting rod 32 is designed as a round rod, and a flat surface 3230 is provided on the outer peripheral wall of the first inclined section 3231. The flat surface 3230 on the first inclined section 3231, while ensuring the structural strength of the lifting rod 32, reduces the radial dimension, making it easier for the front end of the lifting rod 32 to extend into the first lifting position 111 of the handle 11. In this embodiment, the flat surface 3230 is textured. A roller knitting process can be used to design patterns on the flat surface 3230, which can increase the roughness at this location, increase friction, and prevent the handle 11 from wobbling at this location.

[0071] In this embodiment, as shown in FIG20, the lifting rod 32 also has a horizontal section 3234 and a vertical section 3233 connected to each other. The vertical section 3233 bends upward relative to the horizontal section 3234, and the second inclined section 3232 and the vertical section 3233 form a second included angle with each other. Compared with the embodiment in which the second inclined section 3232 is directly connected to the horizontal section 3234, the vertical section 3233 can raise the rear end of the second inclined section 3232, and play a stopping role when the handle 11 slides into the bend of the first included angle along the first inclined section 3231. When performing the action of lifting the handle 11, the handle 11 is stopped at the bend position of the hook-shaped part 323.

[0072] This disclosure provides a container with a movable robotic arm inside. The end of the robotic arm is equipped with the item transfer mechanism 3 described above. This container has all the beneficial effects of the two item transfer mechanisms mentioned above, which will not be elaborated further here.

[0073] Regarding drones, the structure and cooperation of the drone mounting mechanism 4 and handle 11 will be specified next. Specifically, the delivery scenario of food delivery will be used as an example. The transport bag 1 will be referred to as the food bag in the following text.

[0074] As shown in Figures 22 to 24, the mounting mechanism 4 of the UAV includes a base body 41 and a mounting part 42 disposed on the base body 41. The mounting part 42 includes a hook 421 and a limiting rod 422 respectively rotatably mounted on the base body 41. The mounting part 42 has a first state, a second state, and a third state. As shown in Figure 22, when the mounting part 42 is in the first state, the end of the limiting rod 422 abuts against the hook 421 to form a closed limiting space 420. As shown in Figure 24, when the mounting part 42 is in the second state, the end of the limiting rod 422 and the hook 421 are separated and arranged at a first preset distance and / or angle to form a pick-up and drop opening. When the mounting part 42 is in the third state, the end of the limiting rod 422 and the hook 421 are separated, and the hook 421 is rotated to a second preset angle to form a guide slope. The guide slope is used to guide the item mounted on the mounting mechanism to detach from the mounting mechanism.

[0075] In the mounting mechanism provided in this disclosure, the hook 421 and the limiting rod 422 can move towards each other, limiting the handle 11 of the transport bag 1 within the limiting space 420 formed by the limiting rod 422 and the hook 421. At this time, it is in the food hanging state (as shown in Figures 28 and 31), and the drone can carry the transport bag and fly around. When the drone flies to the delivery location, there are two delivery scenarios. One is that the drone transfers the food bag to the item receiving mechanism 3 of the robotic arm, and the item receiving mechanism hangs the food bag on the grid mounting mechanism 21 of the grid 2 to complete the food delivery. During this process, the hook 421 The hook 421 and the limiting rod 422 can be opened outward to the second state, so that the ends of the two are spaced apart and form a pick-up and drop-off port (as shown in Figures 29 and 32), which facilitates the retrieval of food. In another case, the drone directly releases the food bag to the delivery position. In this case, it is a food throwing action. For the second case, the hook 421 and the limiting rod 422 can move in opposite directions to the third state, which is the fully open state. The hook 421 rotates to partially connect with the seat body 41 and form a downward extending guide slope (as shown in Figure 30). The handle 11 of the food bag can throw the food along the guide slope to complete the delivery process.

[0076] The second state is the intermediate position between the first and third states. The first preset angle can be smaller than the second preset angle. The specific value of the preset angle or the size of the pick-up and put-down opening can be designed according to the situation. As shown in Figure 23, in the intermediate position, the ends of the limiting rod 422 and the hook 421 are arranged at intervals to form a pick-up and put-down opening. When the drone flies to the container position, when the item receiving mechanism 3 of the robotic arm moves to the mounting mechanism 4, the hook 421 and the limiting rod 422 can move in opposite directions, opening the limiting space 420. After the item receiving mechanism 3 inserts the first lifting position 111 of the handle, the handle 11 is taken out from the pick-up and put-down opening to complete the food retrieval action. The drone then transfers the food bag to the container. The above describes the food delivery process of the drone. Conversely, the process of transferring the food bag to the drone is also applicable. The food bag can be placed in the limiting space 420 from the pick-up and put-down opening, and the handle 11 of the food bag can be locked in the limiting space 420.

[0077] Regarding the structure of the hook 421 and the limiting rod 422, this disclosure does not limit their functionality. Embodiments where they can be joined together to form a closed limiting space 420, and where the handle 11 can be removed from the loading / unloading port after opening, are all within the scope of this disclosure. In an exemplary embodiment of this disclosure, as shown in Figures 25 and 26, the hook 421 has a mounting arm and a stop arm 4213. A limiting groove 42130 is provided on the surface of the stop arm 4213 facing the limiting rod 422. When the mounting portion 42 is in the first state, the end of the limiting rod 422 is stopped within the limiting groove 42130 and forms the limiting space 420 with the mounting arm. By stopping and limiting the end of the limiting rod 422 through the limiting groove 42130, a closed limiting space 420 can be formed, preventing the limiting rod 422 from accidentally rotating and opening the limiting space 420, thus improving reliability in the hanging state. Meanwhile, after the hook 421 and the limiting rod 422 rotate to the docking position, the hook 421 can continue to rotate due to the limiting groove 42130. During the rotation of the hook 421, the handle 11 will be pushed backward, and the handle 11 will be tightly limited in the limiting space 420, so that the food bag will not shake and the possibility of falling will be reduced.

[0078] As shown in Figure 26, the mounting arm includes a first bent section 4211 and a second bent section 4212 with different widths. The second bent section 4212 is located between the first bent section 4211 and the stop arm 4213. The width of the second bent end 4212 is greater than the width of the first bent section 4211 and less than the width of the stop arm 4213. As shown in Figure 24, when the mounting part 42 is in the second state, the mounting arm drives the stop arm 4213 to move until the side of the stop arm 4213 closest to the seat body 41 contacts the bottom edge of the seat body to form a guide slope. Designing the mounting arm and the stop arm 4213 as multiple segments of different widths can avoid the rotation of the hook 421. When the hook 421 rotates downward to its limit position, it can ensure that the stop arm 4213 is exactly opposite to the seat body 41. In addition, by designing the mounting arm and stop arm 4213, in the first position, the continuously rotating hook 421 can drive the hook 421 to move backward, so that the handle 11 is tightly abutted in the limiting space 420.

[0079] As shown in Figure 25, the mounting mechanism 4 has two mounting parts 42. The main body 41 is provided with a driving member 44 and a moving member 45 that is driven and connected to the driving member 44. The moving member 45 includes a beam and two moving parts connected to both ends of the beam. The two moving parts are driven and connected to the two mounting parts 42 respectively. The forward and backward movement of the moving member 45 can be converted into the rotation of the hook 421 and the limiting rod 422 in the up and down direction. The mounting parts 42 are provided on both sides of the moving member 45. The driving member 44 drives the mounting parts 42 on both sides to move synchronously through the moving member 45. The driving component 44 can be a motor, as shown in Figure 27. The output end of the motor and the beam of the moving component 45 are connected by a lead screw and nut. One end of the lead screw 461 is connected to the motor, and the other end passes through the beam of the moving component 45. The nut 462, threaded onto the lead screw 461, is connected to the seat body 41. The circumferential rotation of the motor can be converted into linear motion of the moving component 45 in the front-back direction through the lead screw and nut, thereby converting it into the up-and-down rotation of the hook 421 and the limiting rod 422, realizing opening and closing. In addition, in the mounting mechanism provided in this disclosure, the driving mechanism is a motor and a lead screw and nut, eliminating the need for electromagnets, etc., which is more cost-effective.

[0080] In this disclosure, as shown in FIG23, the seat body 41 comprises a main body portion 411 and a supporting portion 412 protruding horizontally from the main body portion 411. The main body portion 411 is provided with a first guide groove 4111 for the moving part to move vertically and a second guide groove 4112 for at least partially accommodating the limiting rod 422. The supporting portion 412 is provided with a third guide groove 4121 communicating with the first guide groove 4111. The third guide groove 4121 is used to guide the moving part to move horizontally to push the item toward the guide slope. By designing the structure of the seat body 41, it can be ensured that the forward and backward movement of the moving part in the horizontal direction is not interfered with, and that the rotation of the hook 421 and the limiting rod 422 can proceed smoothly.

[0081] Furthermore, in this disclosure, as shown in FIG27, the seat body 41 also has a guide portion 413 protruding horizontally from the main body portion 411. The guide portion 413 and the bearing portion 412 are respectively located on the front and rear sides of the main body portion 411. The seat body 41 is provided with two guide portions 413, which are respectively connected to two moving parts connected to both ends of the beam. The guide portion 413 includes a first guide member 4131 and a second guide member 4132. The first guide member 4131 and the second guide member 4132 are arranged opposite to each other to form a receiving cavity for accommodating at least part of the moving part. The moving part can move horizontally within the receiving cavity. The guide portions 413 on both sides can bear, guide and limit the moving part 45, ensuring that the moving part can only move horizontally in the front-rear direction. The first guide member 4131 and the second guide member 4132 can be arranged opposite to each other in the vertical direction to form a receiving cavity. It can be a structure that matches the shape of the moving part. In other embodiments, the first guide member 4131 and the second guide member 4132 can also be arranged opposite to each other in the left-right direction, all of which are within the protection scope of this disclosure.

[0082] To convert the forward and backward movement of the moving part 45 into the rotation of the hook 421 and the limiting rod 422, as shown in Figures 25 and 26, the moving part 45 is provided with a first sliding groove 451, a second sliding groove 452, and a third sliding groove 453. The limiting rod 422 includes a first connecting rod 4223 and a second connecting rod 4224 forming an angle between them. The part where the first connecting rod 4223 and the second connecting rod 4224 are connected forms a first rotating part 4221, and the end of the second connecting rod 4224 away from the first connecting rod 4223 forms a second rotating part 4222. The first rotating part 4221 is rotatably connected to the main body 411 and forms a sliding connection with the first sliding groove 451; the second rotating part 4222... The moving part 4222 is slidably connected to the second slide groove 452; the part where the first bent section 4211 and the second bent section 4212 are connected forms the third rotating part 4214, and the end of the first bent section 4211 away from the second bent section 4212 forms the fourth rotating part 4215; the third rotating part 4214 is rotatably connected to the main body part 411, and the fourth rotating part 4215 is slidably connected to the third slide groove 453. The first slide groove 451 can extend in the horizontal direction, and the second slide groove 452 and the third slide groove 453 can extend in the vertical direction, which can convert the linear motion of the moving part in the front-back direction into the synchronous rotation of the hook 421 and the limiting rod 422. When the moving part 45 moves forward, the limiting rod 422 rotates around the first rotating part 4221. Since the first rotating part 4221 is connected to the main body 411, its position is fixed, and the first sliding groove 451 does not affect the horizontal movement of the moving part. At the same time, the second rotating part 4222 slides downward in the second sliding groove 452 until it abuts against the lower end of the second sliding groove 452, and the limiting rod 422 tilts upward. Similarly, the hook 421 rotates around the third rotating part 4214 (its position is fixed), and the fourth rotating part 4215 slides upward in the third sliding groove 453 until it abuts against the upper end of the third sliding groove 453, and the hook 421 rotates downward to open. Conversely, when the moving part 45 moves backward, the hook 421 and the limiting rod 422 close.

[0083] The mounting mechanism 4 provided in this disclosure also includes a sensing element 43 for detecting the mounting status of an item. The sensing element 43 can detect whether the item in the limiting space 420 is properly clamped. There are two sets of sensing elements 43, which are respectively located on both sides of the main body 41. The handle 11 can compress the sensing element 43. The sensor detects the pressure on the sensing element 43 to determine whether the handle 11 is properly installed. After confirming that it is properly installed, the drone flies with the food bag.

[0084] This disclosure provides an unmanned aerial vehicle (UAV) including the mounting mechanism 4 described above. The UAV possesses all the beneficial effects of the aforementioned mounting mechanism, which will not be elaborated upon here.

[0085] As shown in Figure 33, this disclosure provides a cargo delivery system, which includes a transport bag 1, a drone mounting mechanism 4, and an item transfer mechanism 3. The cargo is placed inside the transport bag 1. The transport bag 1 has a handle 11 and a bag body 10 for carrying the cargo. The handle 11 has a first lifting position 111 and a second lifting position 112. The first lifting position 111 of the handle 11 can be lifted onto the lifting rod 32 of the item transfer mechanism 3, and the second lifting position 112 of the handle 11 can be lifted onto the mounting mechanism 4. The cargo delivery system is configured such that the transport bag 1 with the handle 11 can be transferred between the item transfer mechanism 3 and the drone mounting mechanism 4.

[0086] The cargo delivery system disclosed herein includes a container with multiple compartments 2 for storing goods. Each compartment 2 is equipped with a compartment mounting mechanism 21. The second lifting position 112 of the handle 11 can be lifted onto the compartment mounting mechanism 21 and transferred between the compartment mounting mechanism 21 and the goods transfer mechanism 3.

[0087] Specifically, taking the delivery of lunch bags between merchants and users as an example, the merchant places the packaged lunch bag on the rack mounting mechanism 21 of the container. After receiving the delivery instruction, the robotic arm drives the item receiving mechanism 3 to move to the corresponding rack. The camera module 38 obtains the position of the positioning hole 113 on the handle 11 to determine whether the movement is in place. The two lifting rods 32 of the item receiving mechanism 3 extend into the lifting holes 1110 of the handle 11 and move away from each other to enter the concave sections 1101 on both sides, lifting the handle 11 and limiting it at the bend of the hook-shaped part 323, thus completing the item receiving mechanism 3's connection of the lunch bag. The robotic arm moves the goods receiving mechanism 3 and the food bag to the opening at the top of the container, where it docks with the incoming drone on the top landing platform. During this process, the control hook 421 and limit bar 422 are opened to the second position, allowing the handle 11 to be inserted from the loading / unloading port and placed on the support part 412. The control hook 421 and limit bar 422 are then closed to the first position, locking the handle 11 and completing the drone's receiving action of the food bag. At this time, the lifting rod 32 of the goods receiving mechanism 3 can detach from the first lifting position 111, and the two lifting rods 32 move closer together to withdraw from the handle 11, completing the transfer action. The drone can then carry the food bag to the delivery location, and the control hook 421 and limit bar 422 are moved to the third position to drop the food, completing the delivery process.

[0088] Of course, the drone can also transfer the food bag to the item receiving mechanism 3 in the user's community food locker, thus storing the food bag in the designated compartment 2 of the locker for the user to retrieve. This goods delivery system has all the beneficial effects of the handle 11, transport bag 1, receiving mechanism 3, and mounting mechanism 4 mentioned above, which will not be repeated here. This goods delivery system can complete the automatic delivery process of goods, realizing automated receiving of goods with more reliable receiving actions and a simple structure; it can also improve the loading rate of goods, ensure the reliability of mounting, avoid the impact of food box shaking on drone control, and improve the user experience; through the design of the handle 11, it can simultaneously meet the requirements of the receiving mechanism 3 and the mounting mechanism 4; the transport bag 1 has good mass production, simple processing, light weight, low cost, small size, and reusability, which can meet the delivery needs of different goods in drone delivery scenarios.

[0089] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0090] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0091] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
