[0001] This disclosure claims priority to Chinese patent application No. 202420055158.8, filed on January 8, 2024, entitled “Handle and Packaging Bag,” the entire contents of which are incorporated herein by reference. Technical Field

[0002] The present disclosure relates to the technical field of cargo packaging and distribution, and in particular, to a handle and a packaging bag. Background Art

[0003] Packaging bags, such as takeout bags, lunch bags, and transport bags, all feature handles to facilitate carrying, hanging, or hoisting. In related art, these handles are made of soft materials, which can cause pinching and inconvenience during hoisting. This is especially true when transferring bags from one hoisting station to another, where smooth transfers are impossible and bags are prone to falling during hoisting, impacting the user experience. Summary of the Invention

[0004] The purpose of the present invention is to provide a handle and a packaging bag, which can solve the problem that the existing handle is easy to fall off during the lifting process.

[0005] In order to achieve the above-mentioned purpose, the present disclosure provides a handle, which has a main body, and the main body is provided with a hanging hole for a hanging part to pass through, wherein a limiting part is provided on the inner wall of the hanging hole, and the limiting part has an inward concave section and an opening section opened toward the inside of the hanging hole, and the inward concave section is used to circumferentially limit the hanging part, and the hanging part can exit the handle from the opening section.

[0006] In a feasible embodiment, the handle has two fixed arms and a connecting arm connecting the two fixed arms, the two fixed arms and the connecting arm together form the lifting hole, and the limiting parts are respectively provided at the positions where the two fixed arms and the connecting arms are connected, and the opening sections of the two limiting parts are arranged opposite to each other.

[0007] In a feasible embodiment, the handle can pass through the assembly hole on the packaging bag and be fixed on the packaging bag. The handle also has a fixing portion for fixedly connecting to the packaging bag. The fixing portion is connected to one side of the main body and forms a closed lifting hole with the main body.

[0008] In a feasible embodiment, an adhesive layer is provided on a surface of the fixing portion facing the main body portion, so that when the main body portion passes through the assembly hole, the fixing portion is fixed to the packaging bag through the adhesive layer.

[0009] In a feasible embodiment, the handle further includes a reinforcement member, which is fixed to a side of the fixing portion away from the main body portion, and in the length direction, both ends of the reinforcement member respectively extend beyond the fixing portion.

[0010] In a feasible embodiment, at least one of the main body and the reinforcement is provided with a plurality of reinforcing ribs, the plurality of reinforcing ribs are arranged at an angle to each other, and a weight reduction area is formed between two adjacent reinforcing ribs.

[0011] In a feasible embodiment, a positioning hole is provided on the handle near the limiting portion.

[0012] In a feasible implementation manner, the size of the hoisting hole in the length direction is D1, and the size of the hoisting hole in the height direction is D2, wherein 80 mm ≤ D1 ≤ 95 mm, and 30 mm ≤ D2 ≤ 40 mm.

DETAILED DESCRIPTION

[0027] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0028] It should be noted that all actions of acquiring signals, information or data in the present disclosure are carried out in compliance with the corresponding data protection laws and policies of the country where they are located and with the authorization given by the owner of the corresponding device.

[0029] In this disclosure, unless otherwise indicated, directional terms such as "upper, lower, top, and bottom" are generally defined when the transport bag provided by this disclosure is normally placed. "front" and "rear" refer to the directions indicated by the arrows in FIG. 19 . "inside" and "outside" refer to the inside and outside of the corresponding component outlines. The use of terms such as "first" and "second" is intended to distinguish different components and does not indicate order or importance. In addition, in the following description, when referring to the drawings, unless otherwise indicated, the same reference numerals in different drawings indicate the same or similar elements.

[0030] As shown in Figure 1, the present disclosure provides a transport bag 1, which includes a bag body 10 and a handle 11 provided on the bag body 10. The transport bag 1 is not limited to the drone delivery scenario, but can be used in scenarios such as daily hand-carrying by users, delivery by delivery staff, and sales in supermarkets. The transport bag 1 can be a packaging bag for various goods, a takeaway bag, a meal bag, etc. The following will take the design of a meal bag in the drone delivery scenario as an example for a detailed introduction.

[0031] Assume the following delivery scenario: a transport bag 1 containing goods or items is placed in a storage location within a container, as shown in FIG18 . A movable robotic arm 2 is provided within the container, with a docking mechanism 3 at the end of the robotic arm 2. The robotic arm 2 moves to a designated location and places the transport bag 1 in the corresponding storage location onto the docking mechanism 3. The robotic arm 2 drives the docking mechanism 3 and the transport bag 1 to the top opening 20 of the container. An incoming drone lands at a designated location (e.g., a take-off and landing platform on the top of the container) and docks with the docking mechanism 3. The transport bag 1 on the docking mechanism 3 is transferred to the receiving end of the drone and mounted on the drone. The drone carries the transport bag 1 to the delivery location and releases the transport bag 1 at the designated location, completing the drone's automatic delivery process. Conversely, a drone carrying the transport bag 1 can also transfer the goods to the docking mechanism 3 within the container. The robotic arm 2 drives the docking mechanism 3 to the designated storage location and releases the transport bag 1, enabling the automatic transfer of the transport bag 1 between containers in different buildings and between merchants and users.

[0032] Based on the aforementioned delivery scenario, this disclosure has designed a separate article docking mechanism 3 and a drone mounting mechanism 4. Furthermore, the transport bag 1 and its handle 11 have been designed accordingly to the aforementioned structural design. This will be described in detail below with reference to specific embodiments. Of course, the article docking mechanism 3 and drone mounting mechanism 4 are not limited to the aforementioned delivery scenario; any structure capable of docking, hoisting, locking, and releasing the transport bag 1 falls within the scope of this disclosure.

[0033] Regarding the transport bag 1, in the present disclosure, as shown in Figures 1 to 3, the bag body 10 can be made of soft material, and the handle 11 can be made of hard material. As shown in Figure 3, the open portion of the bag body 10 is provided with a first open edge 101 and a second open edge 102 that can be bent, wherein the handle 11 is fixed on the second open edge 102, and a first opening 1011 is provided on the first open edge 101. As shown in Figure 1, the first open edge 101 can be overlapped and fixed on the second open edge 102, and the handle 11 extends from the first opening 1011 for lifting and transportation.

[0034] In the present disclosure, the bag body 10 can be made of a soft material, such as non-woven fabric, and can be integrally formed using a hot pressing or ultrasonic process. The handle 11 can be made of a hard material, such as plastic or a plastic material. It should be noted that the soft material used in the bag body 10 is relative to the hard cardboard of the cardboard box. Compared with the hard cardboard die-cut from sheet materials, the use of soft materials such as non-woven fabric has greater advantages in terms of cost, weight, processing technology, and reuse. The handle 11 is made of a hard material relative to the softer handle on the cardboard box. The handle 11 can maintain its own shape and will not deform. It can ensure that it can be smoothly lifted by the docking mechanism 3 and can also smoothly enter the limited space of the mounting mechanism 4. It can solve the problems of soft handles that strangle the hand and are inconvenient to lift. Especially considering the drone delivery scenario, the handle 11 can ensure the accuracy of the docking action, improve the success rate of mounting, and avoid the impact of the shaking of the meal bag on the drone control. In addition, due to the improvement in material, the sealing form of the handle 11 of the transport bag 1 has been improved to ensure the reliability of the connection at the handle. This can ensure the connection strength at the handle 11 and prevent the handle 11 from falling off during the lifting process, affecting the delivery process.

[0035] In the transport bag 1 provided in the present invention, the material of the bag body 10 is improved, the processing technology is simple, the mass production is better, the cost is low, the weight is light, the occupied volume is small, and it can be reused; the material of the handle 11 is improved, which is more convenient for lifting and prevents strangulation of the hand; combined with the improvement of the material of the bag body 10 and the handle 11, the transport bag 1 adopts a perforated form of the handle 11, which is simpler and more convenient to operate compared with the physical buckle form, and can ensure the strength of the handle 11 position, and the lifting process is more reliable and convenient.

[0036] In the present disclosure, the bag body 10 may have any suitable structure. For example, in the embodiment shown in the figures, the bag body 10 may be a rectangular parallelepiped with an open top. Goods are placed into the bag from the top down. The first and second open sides 101, 102 are bent and overlapped to seal the bag. The top portion is curved, providing ample storage space. In other embodiments, the bag body may have a square, circular, or other structure, and may be open from the side, all of which fall within the scope of protection of the present disclosure.

[0037] After the first open edge 101 overlaps the second open edge 102, the first open edge 101 has an extension portion that extends beyond the second open edge 102, increasing the overlapping area of ​​the two open edges. To prevent the first open edge 101 from warping, a first adhesive portion 13 is provided between the outer surface of the second open edge 102 and the inner surface of the first open edge 101 to secure the first open edge 101 when overlapping the second open edge 102. The first adhesive portion 13 can be double-sided tape, Velcro, etc., which can ensure the sealing of the seal and better protect the goods in the bag.

[0038] The handle 11 can be directly fixed to the second open side 102, and can be fixed by dispensing glue, double-sided tape, or hot pressing. In the present disclosure, as shown in Figures 2 and 3, the handle 11 has a main body 110 and a fixing portion 112. The second open side 102 is provided with a second opening 1021. The main body 110 can pass through the second opening 1021, and the fixing portion 112 is stopped and fixed to the inner surface of the second open side 102. In this embodiment, the main body 110 of the handle 11 passes through the second opening 1021 on the second open side 102 and the first opening 1011 on the first open side 101 in sequence, and then extends out. At the position of the handle 11, a multi-layer structure is designed to strengthen the connection strength at the handle position, preventing the handle 11 from falling out and affecting the lifting. In addition, the fixing portion 112 can stop the inner surface of the second open edge 102, increase the contact area with the second open edge 102, and stably fix the handle 11 on the second open edge 102. Especially in the embodiment where the bag body 10 is made of soft material, the fixing portion 112 can ensure the connection reliability at the position of the handle 11.

[0039] The fixing portion 112 can be fixed to the inner surface of the second open edge 102 in a variety of ways. In the present disclosure, as shown in FIG2 , a second adhesive portion 14 is provided between the fixing portion 112 and the inner surface of the second open edge 102. The second adhesive portion 14 can be an annular structure surrounding the main body 110. The second adhesive portion 14 can be a double-sided adhesive tape that is resistant to high and low temperatures to ensure the fixing strength of the handle. Alternatively, it can be a reusable Velcro tape that allows the handle 11 to be detachable and easily replaced. The second adhesive portion 14 is designed as an annular structure to block the second opening 1021, ensuring the sealing of the transport bag and achieving waterproofing.

[0040] To further enhance the connection strength of the handle 11 to the second open edge 102, as shown in Figure 3, multiple first adhesive portions 13 may be provided, extending in the same direction as the handle 11. The multiple first adhesive portions 13 are located on either side of the handle 11. In this embodiment, the handle 11 and the first adhesive portions 13 both extend longitudinally. The first adhesive portions 13 are provided on the upper and lower sides of the handle 11, respectively, and cooperate with the fixing portion 112 to prevent the handle 11 from falling out of the second opening 1021.

[0041] Considering that the bag body 10 of the transport bag 1 in the present disclosure is made of a soft material, in order to maintain the shape of the bag body 10, in the present disclosure, as shown in Figures 2 and 4, the transport bag also includes a liner 12 provided in the bag body 10. The liner 12 can be placed on the bottom wall of the bag body 10, which can enhance the carrying capacity of the transport bag 1 for the goods in the bag, while also constraining and fixing the goods in the bag. The liner 12 can be designed according to the type of goods. In an exemplary embodiment of the present disclosure, as shown in Figure 4, the liner 12 has a bottom plate 121 and a plurality of flanges 122 provided on the periphery of the bottom plate 121. The bottom plate 121 is used to fit against the bottom wall of the bag body 10, and the plurality of flanges 122 are folded upward to form a storage space with the bottom wall of the bag body 10.

[0042] To reduce the space occupied by the transport bag 1, the transport bag 1 provided by the present disclosure is foldable. As shown in FIG3 , a plurality of folds 104 are provided on the opposite side walls of the bag body 10, which enable the transport bag 1 to be folded into a flat plate with the bottom folded to one side of the flat plate. The plurality of folds 104 include a first fold extending vertically in the middle of the side wall, and two second folds forming a Y-shape with the first fold, so that the bag body 10 can be folded in half from the middle to form a flat plate. The fold 104 also includes a third fold located above the second fold, which is arranged perpendicular to the first fold. The third fold can be used to fold the bottom of the bag body 10 to one side of the flat plate. This is particularly suitable for embodiments in which a lining 12 is provided at the bottom. The lining 12 of the above-mentioned structure does not affect the folding of the transport bag 1. The position of the third fold can be designed according to the height of the lining 12, which is not specifically limited by the present disclosure. The folding process is similar to that of a clothing paper bag and will not be described in detail here.

[0043] As shown in Figure 5 , the transport bag 1 provided by the present disclosure has a folded storage state, which does not take up space and can be folded away for future use. As shown in Figure 3 , the transport bag 1 also has an open state, facilitating the placement of goods through the top opening. As shown in Figure 1 , the transport bag also has a closed state, where goods are placed inside the bag, the opening is closed, and the handle 11 remains ready for lifting and carrying. The transport bag 1 can be switched between these three states at will, making operation simple.

[0044] Next, the structures of the docking mechanism 3 and the handle 11 and the cooperation between the two are introduced to smoothly complete the docking action.

[0045] The present disclosure has standardized the design of the handle of the transport bag 1. As shown in Figures 6 to 8, the present disclosure provides a handle 11. The main body 110 of the handle 11 is provided with a hoisting hole 1101 for the hoisting part to pass through, wherein a limiting portion 111 is provided on the inner wall of the hoisting hole 1101. The limiting portion 111 can at least limit the hoisting part in the circumferential direction, and can enable the hoisting part to disengage from the limiting portion 111 along a preset direction and exit the handle 11. Here, the hoisting part can be the hoisting rod 32 of the connecting mechanism 3 described below, or it can be a hoisting structure of other structural forms, such as a hook, a clamping claw arm, a hanging arm, etc. The handle 11 can be the handle of the transport bag 1 described above.

[0046] In the standardized handle provided in the present invention, the lifting part extends into the lifting hole 1101 and cooperates with the limiting part 111 to achieve locking between the handle 11 and the lifting part, so that the transport bag 1 is stably lifted on the lifting part to ensure that it will not fall during the lifting process. After lifting to the specified position, the lifting part can be easily detached from the limiting part 111 and withdrawn from the handle 11, and the transport bag 1 can be easily removed from the lifting part, which can not only ensure stability during the lifting process, but also will not affect the subsequent transfer process of the transport bag 1.

[0047] Accordingly, as shown in Figures 10 to 17, the present disclosure provides an article docking mechanism 3, which can realize the docking action of any article. For example, the "article" here can be the handle of the transport bag 1 mentioned above. The transport bag 1 with a handle 11 provided by the present disclosure will be taken as an example for detailed introduction below. The docking mechanism 3 includes a base body 31 and two parallel hoisting rods 32. The first end of the hoisting rod 32 is installed in the base body 31, and the second end is used to clamp the article. The base body 31 is provided with a power member 34 for driving the hoisting rod 32 to move and a transmission member 35 arranged between the power member 34 and the hoisting rod 32. The power member 34 drives the two hoisting rods 32 to move synchronously through the transmission member 35 to move closer to or away from each other. By controlling the power member 34, the movement of the two hoisting rods 32 can be automatically controlled. The two hoisting rods 32 share the same power member and move synchronously, which can save the arrangement of the power member 34, reduce the occupied space, and make the structure more compact. Of course, the two hoisting rods 32 can also be driven separately, which all falls within the protection scope of the present disclosure.

[0048] In the docking mechanism 3 provided in the present invention, the power part 34 drives the two lifting rods 32 to move through the transmission part 35, and can automatically adjust the distance between the two lifting rods 32, so that the docking mechanism 3 can be suitable for objects of different specifications and types. The second end of the lifting rod 32 can stably clamp the object and can complete the docking action accurately and reliably. The docking mechanism can achieve high-reliability docking with the object and realize automatic docking, and the docking action is more reliable and the operation is more convenient.

[0049] Taking the use of the docking mechanism 3 to dock a transport bag 1 with a handle 11 as an example, the second end of the lifting rod 32 can be extended into the lifting hole 1101 of the handle 11, and the two lifting rods 32 can approach or move away from each other to respectively enter the limiting part 111 of the handle 11 for locking, or disengage from the limiting part 111 and exit the handle 11.

[0050] Limiting portions 111 are provided on the inner walls opposite to the hoisting hole 1101. The two hoisting rods 32 are brought closer together to be able to extend into the hoisting hole 1101. Thereafter, the two hoisting rods 32 move away from each other and enter and lock into their respective limiting portions 111. At this point, the docking mechanism 3 completes the docking action with the transport bag 1 and can drive the transport bag 1 to move. For example, after docking with a drone and transferring the transport bag 1 to the drone, the two hoisting rods 32 can move closer together, disengage from the corresponding limiting portions 111, and exit the handle 11, completing the unlocking of the docking mechanism 3. This docking mechanism 3 can achieve highly reliable docking with the transport bag 1, realize automated docking, and provide more reliable docking and more convenient operation.

[0051] As shown in Figure 18, the docking mechanism 3 can be installed on the robotic arm 2 of the container. The movement of the robotic arm 2 drives the docking mechanism 3 to move, and after docking the transport bag 1, it drives the transport bag 1 to move. Of course, the docking mechanism 3 can also be installed in any scenario where the transport bag 1 needs to be hoisted.

[0052] The limiting portion 111 can be any appropriate structure, and can be a limiting hole. After the hanging rod 32 is inserted into the hanging hole 1101, the limiting portion 111 can not only achieve circumferential limiting, but also achieve axial limiting by cooperating with the hanging rod 32. The limiting portions that can achieve this limiting effect belong to the protection scope of the present disclosure. In an exemplary embodiment of the present disclosure, as shown in Figure 8, the limiting portion 111 can be a notch opened on the inner wall of the hanging hole 1101, and the notch has a concave section 1111 and an opening section 1112 opened toward the inside of the hanging hole 1101. The concave section 1111 is used to limit the hanging rod 32 circumferentially. The hanging rod 32 can exit the handle 11 from the opening section 1112, and the direction of the opening section 1112 is a preset direction. Specifically, in this embodiment, as shown in FIG8 , the handle 11 has two fixed arms and a connecting arm connecting the two fixed arms. The two fixed arms and the connecting arm together form a hanging hole 1101. Here, the hanging hole 1101 can be rectangular to facilitate the insertion of the hanging rod 32. A limiting portion 111 is provided at the location where the two fixed arms and the connecting arm are connected. The openings 1112 of the two limiting portions 111 are arranged opposite each other, that is, the two limiting portions 111 are respectively provided at two opposite corners of the handle 11, corresponding to the two hanging rods 32. In this embodiment, the concave section 1111 can be a two-thirds circular arc, and the remaining one-third circular concave section forms the opening section 1112. The specific design can be based on the shape and shaft diameter of the hanging rod 32. One end of the opening section 1112 can be designed to be rounded to facilitate the withdrawal of the two hanging rods 32 from the limiting portion 111 when they approach each other, thereby achieving circumferential limitation without affecting unlocking. It should be understood that the concave section 1111 may also be other shapes that can play a circumferential limiting role on the hanging rod 32.

[0053] As shown in Figure 8, the width of the fixed arms on both sides gradually increases from one end of the opening 1112 to the direction away from the connecting arm, which can play a reinforcing role. At the position of the limiting portion 111, the structural strength of the handle 11 itself is increased without affecting the insertion and withdrawal of the lifting rod 32.

[0054] The limiting portion 111 is used to limit the circumferential position of the hanging rod 32. Furthermore, in order to achieve axial limitation and clamping of the article, as shown in Figures 10 and 15, the second end of the hanging rod 32 is provided with a fixed block 321 and a movable block 322. The movable block 322 can move axially to clamp the handle 11 in the gap 320 between the fixed block 321 and the movable block 322. By adjusting the axial position of the movable block 322, handles 11 of different specifications can be fixed. The size of the gap 320 can be designed according to the wall thickness of the main body 110 of the handle 11. The movable block 322 moves toward the fixed block 321 to clamp the handle 11. The movable block 322 moves away from the fixed block 321 to unlock the handle 11. By setting the movable block 321 and the fixed block 322, the handle 11 can be stably fixed at the specified position of the lifting rod 32 without shaking in the axial direction, and cooperate with the limiting part 111 to ensure the stability and reliability of the lifting of the transport bag 1 after connection.

[0055] The movable block 322 can be adjusted in the axial direction in a variety of ways, such as by being threadedly connected to the lifting rod 32. In the present disclosure, a stopper 323 is provided on the lifting rod 32 on the side of the movable block 322 away from the fixed block 321, and an elastic member 33 is provided between the stopper 323 and the movable block 322. When unlocking is required, the movable block 322 moves away from the fixed block 321, compressing the elastic member 33 and increasing the gap 320. When locking is required, the movable block 322 automatically moves toward the fixed block 321 under the action of the restoring force of the elastic member 33 to perform the clamping action.

[0056] In the present disclosure, at least one of the movable block 322 and the fixed block 321 is provided with a guide slope, which extends obliquely toward the gap 320. In the embodiment shown in FIG10 , only the movable block 322 is provided with the guide slope 3221. The robotic arm 2 drives the docking mechanism 3 to move and extend into the hanging hole 1101 of the handle 11. When the robotic arm 2 extends forward too far, even if the handle 11 is located at the position of the guide slope 3221, it can automatically slide along the guide slope 3221 into the gap 320.

[0057] In the embodiment shown in Figure 15, the movable block 322 and the fixed block 321 are respectively provided with guide slopes, the fixed block 321 has a conical surface and a first guide slope 3211 extending toward the gap 320, and the movable block 322 has a second guide slope 3221 extending toward the gap 320. The handle 11 of the transport bag 1 is placed within the range of the first guide slope 3211 and the second guide slope 3221. The handle 11 can automatically slide into the gap 320, reducing the restriction on the docking position and making it easier to complete the docking action.

[0058] In order to further enhance the connection strength at the position of the handle 11, as shown in Figures 6 and 7, the handle 11 also includes a reinforcement 114, which is fixed to the side of the fixing portion 112 away from the main body 110. The reinforcement 114 serves as the load-bearing part of the handle 11 and the bag body 10, distributing the weight of the goods to the reinforcement 114 and the main body 110, avoiding concentrated force on the main body 110 and ensuring uniform force.

[0059] As shown in Figures 3 and 8, the two ends of the reinforcement 114 extend beyond the fixed portion 112 respectively, and a step portion 103 is provided at the top opening of the bag body 10. As shown in Figure 1, in the packaged state of the transport bag 1, the reinforcement 114 can be overlapped on the side wall opposite to the opening and limited by the step portion 103, playing a supporting and limiting role to prevent the transport bag 1 from deformation during the lifting process.

[0060] Furthermore, to enhance the structural strength of the handle 11, as shown in Figure 8, at least one of the main body 110 and the reinforcement 114 is provided with a plurality of reinforcing ribs 115, arranged at angles to one another. The areas between the ribs 115 are designed to reduce weight while maintaining the strength of the handle 11, in line with lightweight design principles.

[0061] As shown in Figure 9, the present disclosure standardizes the dimensions of the handle 11. The length dimension of the hanging hole 1101 is D1, and the height dimension is D2, where 80mm ≤ D1 ≤ 95mm and 30mm ≤ D2 ≤ 40mm. D1 can be determined by the width of four fingers, allowing the user to easily insert and remove the handle 11 when carrying the transport bag 1. The dimension of D2 should be designed taking into account the thickness of the fingers, the axial diameter of the hanging rod 32, and the relevant structures of the drone receiving end, ensuring that the above structures can freely insert and remove the hanging hole 1101. The maximum distance between the two hanging rods 32 in the docking mechanism 3 and the distance between the two side guides 451 in the mounting mechanism 4 can be designed based on D1. The length of the reinforcement 114 is D3, where 200mm ≤ D3 ≤ 300mm, and can be specifically designed based on the length of the bag body 10. Through the design of the shape, size, and material of the handle 11, the handle 11 can withstand an impact force of 16N.

[0062] In the present disclosure, as shown in FIG7 , a positioning hole 113 is provided on the handle 11 near the limiting portion 111. As shown in FIG18 , the base 31 of the docking mechanism 3 can be detachably connected to the robotic arm 2 by fasteners, and the robotic arm 2 can move to drive the docking mechanism 3 to move. As shown in FIG16 , the docking mechanism 3 also includes a camera module 38 provided on the base 31, and the camera module 38 is used to obtain position information of the positioning hole 113 on the handle 11. The position information of the positioning hole 113 on the handle 11 is obtained by the camera module 38, and the position information is transmitted to the robotic arm 2, thereby controlling the movement of the robotic arm 2, and then adjusting the relative position of the docking mechanism 3 and the handle 11, ensuring that the lifting rod 32 can be smoothly inserted into the lifting hole 1101, thereby successfully completing the docking action.

[0063] As shown in Figure 8, the fixed arms on either side of the handle 11 are each provided with a plurality of positioning holes 113. Three or four positioning holes 113 can be provided, and the camera module 38 can quickly and accurately detect the positions of the positioning holes 113, thereby determining the position of the handle 11. The positioning holes 113 are designed to be close to the stopper 111. The positioning holes 113 can be combined with the stopper 111, and the stopper 111 confirms that the acquired holes are positioning holes 113, thus avoiding errors in the position of the positioning holes 113 and ensuring the accuracy of visual recognition.

[0064] Furthermore, in the connecting mechanism 3 , there are multiple ways to achieve the automatic approach or separation of the two hanging rods 32 .

[0065] In the first exemplary embodiment of the present disclosure, as shown in FIG11 , a first chute 311 and a second chute 312 are provided on the base body 31 in a parallel and staggered arrangement. The first chute 311 and the second chute 312 correspond to two hanging rods 32, respectively. The hanging rod 32 has a straight portion 324 located in the corresponding chute and an extension portion 325 forming an angle with the straight portion 324. Compared with the embodiment in which the two chute are arranged in parallel, the parallel and staggered arrangement of the two chute can increase the distance between the two hanging rods 32 when they are separated from each other, thereby expanding the range of the applicable hanging hole 1101. At the same time, by arranging the angle of the extension portion 325, the two hanging rods 25 can be located at the same height, which facilitates insertion into the hanging hole 1101.

[0066] In the first exemplary embodiment of the present disclosure, as shown in Figures 12 to 14, two guide rails 36 and sliders 37 are provided within the base 31, each slidably mounted on the corresponding guide rails 36. The transmission member 35 includes a gear 351 connected to the output shaft of the power member 34 and racks 352 connected to the corresponding sliders 37. The first ends of the two hanging rods 32 are respectively connected to the corresponding racks 352. The two racks 352 are arranged in parallel and respectively mesh with the gears 351. The power member 34 can be a motor, and the gear 351 is connected to the output shaft of the motor to transmit power to the racks 352. The racks 352 on both sides respectively drive the corresponding sliders 37 to perform linear motion along the guide rails 36, thereby driving the two hanging rods 32 closer or farther away.

[0067] In a second exemplary embodiment of the present disclosure, as shown in FIG15 , 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 connected between the movable seat 353 and the first end of each suspension rod 32. That is, a multi-link mechanism 354 is provided between each suspension rod 32 and the movable seat 353. The power member 34 sequentially transmits power to the movable seat 353 and the multi-link mechanism 354 to convert the power into movement of the suspension rod 32. Specifically, in this embodiment, as shown in FIG15 , 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-link mechanism that is sequentially hinged. The front end of the four-link mechanism is rotatably connected to the hinged rod 3532, and the rear end is linked to the seat body 31. The first end of the suspension rod 32 is connected to the hinge point of two of the links of the four-link mechanism. The circumferential rotation of the power member 34 is converted into 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 hanging rods 32 into a closer or farther distance. The transmission member 35 is not limited to the rack and pinion and multi-link mechanism shown in the above embodiment, and can also be a linear module, chain mechanism, etc.

[0068] The present disclosure also provides a cargo container, in which a robotic arm 2 is movably disposed. As shown in FIG18 , a linear module 21 is provided within the container, and the container has a top opening 20. The robotic arm 2 can move a docking mechanism 3 and a transport bag 1 to the top opening 20, positioning the docking mechanism 3 at the top opening for docking with an incoming drone. This cargo container exhibits all the beneficial effects of the aforementioned docking mechanism 3, and further details are omitted here.

[0069] The robotic arm 2 may be composed of multiple sections at angles to each other, so as to drive the docking mechanism 3 to move in different directions. The side of the base 31 used for connection with the robotic arm 2, i.e., the side of the base 31 away from the lifting rod 32, has a reduced diameter section 313 for avoiding interference, which is used to avoid the robotic arm 2. In the second exemplary embodiment of the present disclosure, considering the possible interference between the docking mechanism 3 and the robotic arm 2, as shown in FIG17 , the size of a portion of the base 31 is reduced, for example, from the square design of the first embodiment to the cylindrical design of the second embodiment. This reduction in the size of the base 31 conforms to the principle of lightweight design, while effectively avoiding interference and ensuring that the robotic arm 2 moves in different directions.

[0070] Next, the present disclosure introduces the structure of the receiving end and the handle 11 of the drone and the way the two cooperate.

[0071] As shown in Figures 19 to 22, the present disclosure provides a mounting mechanism 4, which can be installed on delivery entities such as drones, delivery vehicles, and robots, and can be used to mount various types of items. Specifically, the structure of the mounting mechanism 4 will be introduced in detail below by taking the above-mentioned transport bag 1 with a handle 11 and the mounting mechanism 4 installed on a drone as an example.

[0072] The non-mounting mechanism 4 includes a seat body 41, a locking piece 42 and a locking tongue 43. The seat body 41 is used to be detachably mounted on the fuselage of the drone; the seat body 41 is provided with a support seat 411, and the locking piece 42 is rotatably mounted on the support seat 411. The locking piece 42 has a first piece 421 and a second piece 422. The first piece 421 and the second piece 422 are connected at one end and form an angle. The first piece 421 drives the second piece 422 to rotate to form a limited space with part of the top of the seat body 41. The handle 11 of the transport bag 1 can abut against the first piece 421 and can enter the limited space between the first piece 421 and the second piece 422. The locking tongue 43 is movably mounted on the top of the seat body 41. The locking tongue 43 is used to prevent or restore the rotation of the second piece 422.

[0073] The lock tongue 43 includes a shell 431 and a tongue piece 432. The tongue piece 432 is located below the shell 431 and is elastically connected to the shell 431. The tongue piece 432 has a first state in which it extends out of the shell 431 and a second state in which it is at least partially retracted into the shell 431. When the lock plate 42 rotates until the second piece 422 abuts against the lock tongue 432, the tongue piece 432 enters the second state to allow the second piece 422 to pass through the position of the tongue piece 432 in the forward direction; when the lock plate 42 moves to the position where a limited space is formed, the tongue piece 432 enters the first state to prevent the second piece 422 from passing through the position of the tongue piece 432 in the reverse direction.

[0074] In the mounting mechanism 4 provided in the present invention, the driving force for the rotation of the locking plate 42 comes from the handle of the transport bag 1. That is to say, only when the handle 11 moves into place can the handle 11 be limited and locked, so that the transport bag 1 can be accurately mounted, and at the same time, the reliability after mounting can be guaranteed to prevent items from falling during transportation.

[0075] Taking the embodiment shown in Figure 26 as an example, the transport bag 1 is hoisted on the docking mechanism 3, and the robotic arm 2 drives the docking mechanism 3 and the transport bag 1 toward the receiving end of the drone. The handle 11 continues to move forward after contacting the first piece 421, driving the locking piece 42 to rotate counterclockwise. When it rotates to the second piece 422 abutting against the tongue 432, the tongue 432 is compressed to partially retract it into the shell 431, so that the second piece 422 passes over the tongue 432, and the handle 11 enters the limited space formed by the first piece 421, the second piece 422 and the seat body 41. The tongue 432 automatically extends out of the shell 431 under the action of the elastic restoring force, locks the second piece 422, prevents the locking piece 42 from rotating, and completes the drone's reception and locking action of the handle 11, entering the state shown in Figure 29. At this time, the robotic arm 2 drives the docking mechanism 3 to move forward, compressing the elastic part 33, increasing the gap 320 between the movable block 322 and the fixed block 321, unlocking the connection between the lifting rod 32 and the handle 11 in the axial direction, and the power part 34 drives the two lifting rods 32 to approach each other, disengaging from the limit part 111 and exiting the handle 11, handing over the transport bag 1 to the drone, and entering the state shown in Figures 27 and 28. The drone carries the transport bag 1 to the delivery location, realizing the transfer of goods between different buildings, different containers, users and merchants.

[0076] On the contrary, the process of the drone handing over the transport bag 1 to the docking mechanism 3 is similar and will not be repeated here. Alternatively, after the drone carries the transport bag 1 to the delivery location, it can automatically open the lock tongue 43 and release the handle 11. The handle 11 will fall along the first guide surface 4110 described below, placing the transport bag 1 at a predetermined position, completing the automatic delivery process.

[0077] As shown in Figures 23 and 24, the lock tongue 43 also includes a stop piece 433, which is arranged on the side of the shell 431 away from the tongue piece 432 and is spaced apart from the tongue piece 432. The stop piece 433 is used to lock the second piece 422 between the stop piece 433 and the tongue piece 432. The height of the stop piece 433 is configured so as not to affect the forward rotation of the first piece 421, and when the handle 11 is in the limited space, it can limit the handle 11 and the second piece 422 to ensure that the position of the handle 11 in the limited space is fixed. In this way, the drone will not be affected by the flight of the drone while carrying the transport bag 1, thereby ensuring stability during the flight.

[0078] When the second plate 422 is positioned between the tongue 432 and the stopper 433, the locking tongue 43 can move away from the locking plate 42 to release the tongue 432 from restricting the rotation of the second plate 422. In the present disclosure, as shown in FIG19 , the handle 11 moves forward and backward into the restricted space. The locking tongue 43 is positioned above the locking plate 42 and can move forward and backward. As the locking plate 42 rotates toward the position defining the restricted space, the locking tongue 43 remains fixed in its forward and backward position. To release the handle 11, the locking tongue 43 moves backward, the locking plate 42 rotates clockwise, and the handle 11 automatically slides down along the second plate 422 and the first guide surface 4110, described below.

[0079] As shown in FIG22 , the seat body 41 is also provided with a driving member 44 for driving the lock tongue 43 to move back and forth. The driving member 44 can be a linear module or a linear motor, etc., which can drive the entire lock tongue 43 to move back and forth. In the present disclosure, as shown in FIG25 , the tongue piece 432 can extend or retract into the housing 431. A spring is provided in the housing 431. One end of the tongue piece 432 is connected to the spring, and the other end extends out of the housing 431. By manually pressing the tongue piece 432 upward, the lock can be unlocked when the driving member 44 fails. The locking end of the tongue piece 432 is designed as a hook-shaped structure, and the locking end of the second piece 422 adopts a widened design to increase the contact area with the tongue piece 432 and ensure the reliability of the locked position.

[0080] As shown in Figure 22, the mounting mechanism 4 also includes a suction component 46 for fixing the first sheet 421. When the handle 11 is located in the limited space, the suction component 46 can be energized to suction and fix the first sheet 421 to avoid abnormal noise caused by the rotating locking piece 42. When the handle 11 needs to be released, the suction component 46 is de-energized to release the first sheet 421.

[0081] As shown in Figures 19 and 20, the seat body 41 has a support base 411 positioned in the middle. The locking plate 42 is rotatably mounted within the support base 411. The support base 411 has a first guide surface 4110. The handle 11 can move along the first guide surface 4110 to drive the locking plate 42 to rotate and enter the confined space. Compared to drones with dual-ear mounting, the present invention adopts a single-handle mounting method in the middle. This method is simple and reliable, with a high mounting success rate. It can also eliminate the impact of the transport bag 1's vibration on the drone's control and ensure the stability of the drone carrying the transport bag 1 during flight. The first guide surface 4110 guides the handle 11 as it moves toward the confined space. When the locking tongue 43 releases the handle 11, the handle 11 automatically slides down along the first guide surface 4110 under the action of gravity, also providing guidance and cushioning.

[0082] As shown in FIG21 , the mounting mechanism 4 provided by the present disclosure further includes a connecting seat 45 connected to the seat body 41. The connecting seat 45 includes a main body connected to the seat body and a guide portion 451 located outside the main body. The guide portions 451 are provided on both sides of the support seat 411. The guide portions 451 on both sides have second guide surfaces 4510 that are inclined and gradually approach inward. As shown in FIG26 , when the docking mechanism 3 carrying the transport bag 1 moves toward the mounting mechanism 4, as shown in FIG29 , the second guide surfaces 4510 on both sides are used to guide the docking mechanism 3 with the transport bag 1 hoisted thereon toward the support seat 411 so as to quickly find the position of the locking plate 42 and ensure the smooth and rapid completion of the transfer operation.

[0083] As shown in FIG27 , the distance between the two side guides 451 is greater than the length dimension D1 of the handle 11 , and the handle 11 can be located in the space between the two side guides 451 to perform receiving operations with the drone receiving end.

[0084] The present disclosure also provides a drone, equipped with the aforementioned mounting mechanism. The mounting mechanism 4 is detachably mounted on the drone's fuselage. The drone exhibits all the benefits of the drone mounting mechanism 4, which will not be further elaborated here. Of course, the mounting mechanism 4 can also be installed anywhere a transport bag 1 is required, such as on an airplane or a car, without limitation in the present disclosure.

[0085] Next, the present disclosure provides a cargo delivery system, as shown in Figure 29, including the transport bag 1, cargo docking mechanism 3 and drone mounting mechanism 4 introduced above, and the transport bag 1 with a handle 11 can be transferred between the cargo docking mechanism 3 and the drone mounting mechanism 4. For example, it can be a delivery between a user and a merchant. The merchant places the packaged meal bags on the storage position of the container. After receiving the delivery instruction, the robotic arm 2 drives the docking mechanism 3 to move to the storage position (the position of the positioning hole 113 on the handle 11 is obtained by the camera module 38 to determine whether it has moved into place). The two lifting rods 32 of the docking mechanism 3 extend into the lifting hole 1101 of the handle 11, and move away from each other to enter the limiting parts 111 on both sides respectively, and are locked and fixed by the movable block 322 and the fixed block 321 to complete the docking action of the docking mechanism 3 to the meal bag; the robotic arm 2 drives the docking mechanism 3 and the meal bag to the opening at the top of the container, and docks with the flying drone on the top take-off and landing platform. In this process, the second guide surface 4510 can play a guiding role. The robot arm 2 then moves forward to the position of the support seat 411. The robot arm 2 then continues to drive the docking mechanism 3 and the meal bag forward. The handle 11 contacts the first plate 421, driving the second plate 422 to rotate. The second plate 422 compresses and passes over the tongue 432, causing the handle 11 to enter the limited space between the first plate 421 and the second plate 422. The tongue 432 extends out of the housing 431 to stop the second plate 422, locking the handle 11 and completing the drone mounting mechanism 4 receiving the meal bag. At this point, the docking mechanism 3 moves forward, compressing the elastic member 33. The distance between the movable block 322 and the fixed block 321 increases, allowing the lifting rod 32 to disengage from the limiting portion 111. The two lifting rods 32 approach each other and exit the handle, completing the transfer. The drone can now carry the meal bag to the delivery location. The locking tongue 43 moves backward to open the locking plate 42, and the handle 11 automatically slides down along the first guide surface 4110, completing the delivery process.

[0086] Of course, the drone can also transfer the meal bag to the docking mechanism in the dining cabinet in the user's community, so that the meal bag is stored in the designated storage position of the dining cabinet and is ready for the user to take away. The cargo delivery system has all the beneficial effects of the above-mentioned handle 11, transport bag 1, docking mechanism 3 and mounting mechanism 4, which will not be repeated here. The cargo delivery system can complete the automatic delivery process of the goods, which can not only realize the automatic docking of the goods, but also make the docking action more reliable and simple in structure; and it can also improve the mounting rate of the goods, ensure the mounting reliability, avoid the influence of the shaking of the lunch box on the control of the drone, and improve the user experience; through the standardized design of the handle 11, it can meet the requirements of the docking mechanism 3 and the mounting mechanism 4 at the same time, and the transport bag 1 has good mass production, simple processing, light weight, low cost, small size, and is reusable, which can meet the delivery needs of different goods in the drone delivery scenario.
