DETAILED DESCRIPTION

[0031] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0032] It should be noted that all actions of acquiring signals, information or data in the present disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the device is located and with the authorization given by the owner of the corresponding device.

[0033] In the present disclosure, unless otherwise stated, directional words such as "upper, lower, top, bottom" are generally defined when the transport bag provided by the present disclosure is normally placed, and "front, back" refers to the position of the transport bag. Figure 19 In the direction indicated by the arrow, "inside" and "outside" refer to the inside and outside of the corresponding component outline, and the terms "first" and "second" are used to distinguish different components and do not have order and importance. In addition, in the following description, when referring to the drawings, unless otherwise explained, the same reference numerals in different drawings represent the same or similar elements.

[0034] like Figure 1 As shown, the present disclosure provides a transport bag 1, which includes a bag body 10 and a handle 11 arranged 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 deliverymen, 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.

[0035] Assume the following distribution scenario: a transport bag 1 containing goods or articles is placed on a storage location in a container, such as Figure 18 As shown, a movable mechanical arm 2 is provided in the container, and a docking mechanism 3 is provided at the end of the mechanical arm 2. The mechanical arm 2 moves to the designated position to place the transport bag 1 on the corresponding storage position on the docking mechanism 3. The mechanical arm 2 drives the docking mechanism 3 and the transport bag 1 to move to the top opening 20 of the container. The flying drone lands at the designated position (for example, the 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 will be transferred to the receiving end of the drone, and the transport bag 1 will be mounted on the drone. The drone carries the transport bag 1 and flies to the delivery location, and releases the transport bag 1 at the designated location of the delivery location, completing the automatic delivery process of the drone. On the contrary, the drone carrying the transport bag 1 can also transfer the goods to the docking mechanism 3 in the container. The mechanical arm 2 drives the docking mechanism 3 to move to the designated storage position and releases the transport bag 1, realizing the automatic transfer of the transport bag 1 between containers in different buildings and between merchants and users.

[0036] Based on the above delivery scenario, the present disclosure designs a separate article connection mechanism 3 and a mounting mechanism 4 for the drone, and makes corresponding designs for the transport bag 1 and the handle 11 of the transport bag 1. The following will be introduced in detail in combination with specific embodiments. Of course, the article connection mechanism 3 and the mounting mechanism 4 for the drone are not limited to the above delivery scenario, and any structure that can achieve connection, hoisting, locking, and releasing of the transport bag 1 belongs to the protection scope of the present disclosure.

[0037] Regarding the transport bag 1, in the present disclosure, as Figures 1 to 3 shown, the bag body 10 can be made of a soft material, and the handle 11 can be made of a hard material. As Figure 3 shown, at the open end of the bag body 10, there are provided a first open edge 101 and a second open edge 102 that can be bent. Among them, 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 Figure 1 shown, the first open edge 101 can be overlapped and fixed on the second open edge 102, and the handle 11 extends out from the first opening 1011 for hoisting transportation.

[0038] 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 by hot pressing or ultrasonic technology. The handle 11 can be made of a hard material, such as plastic or plastic material. Here, it should be noted that the soft material used for the bag body 10 is relative to the cardboard of the cardboard box. Compared with the cardboard cut and formed by the board, using soft materials such as non-woven fabric has greater advantages in terms of cost, weight, processing technology, and reuse. The handle 11 made of a hard material is relative to the softer handle on the cardboard box. The handle 11 can maintain its own shape without deformation, can be smoothly lifted by the connection mechanism 3, and can also smoothly enter the limiting space of the mounting mechanism 4. It can solve the problems of the soft handle being strenuous and inconvenient for hoisting. Especially considering the drone delivery scenario, the handle 11 can ensure the accuracy of the connection action, improve the success rate of mounting, and avoid the influence of the meal bag shaking on the drone control. In addition, at the position of the handle 11 of the transport bag 1, due to the improvement in the material, the sealing form is improved to ensure the connection reliability at the handle position, avoid the handle 11 falling off during hoisting, and affect the delivery process.

[0039] 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 the hand from being strangled; 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 than the physical buckle form, and at the same time can ensure the strength of the handle 11 position, and the lifting process is more reliable and convenient.

[0040] In the present disclosure, the bag body 10 can be any appropriate structure. Taking the embodiment shown in the figure as an example, the bag body 10 can be a rectangular parallelepiped structure with an open top design. The goods are placed in the bag from top to bottom. The first open edge 101 and the second open edge 102 are bent and overlapped to seal. The top is an arc-shaped structure design with a large storage space. In other embodiments, the bag body can also be a square, circular or other structure, and can be open from the side, all of which belong to the protection scope of the present disclosure.

[0041] After the first open edge 101 overlaps the second open edge 102, the first open edge 101 has an extension portion extending beyond the second open edge 102, increasing the overlapping area of ​​the two open edges, and 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, so as to fix the first open edge 101 when it overlaps the second open edge 102. The first adhesive portion 13 can be a double-sided adhesive tape, Velcro, etc., which can ensure the sealing of the sealing portion and better protect the goods in the bag.

[0042] The handle 11 can be directly fixed on the second open edge 102, and can be fixed by using glue, double-sided tape or hot pressing. Figure 2 and Figure 3 As shown, the handle 11 has a main body 110 and a fixing part 112. The second open edge 102 is provided with a second opening 1021. The main body 110 can pass through the second opening 1021, and the fixing part 112 stops and is fixed on the inner surface of the second open edge 102. In this embodiment, the main body 110 of the handle 11 passes through the second opening 1021 on the second open edge 102 and the first opening 1011 on the first open edge 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 position of the handle to prevent the handle 11 from coming out and affecting the hoisting. In addition, the fixing part 112 can stop on 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 part 112 can ensure the connection reliability at the position of the handle 11.

[0043] The fixing part 112 can be fixed on the inner surface of the second open edge 102 in various ways. In the present disclosure, as Figure 2 shown, a second bonding part 14 is provided between the fixing part 112 and the inner surface of the second open edge 102. The second bonding part 14 can be an annular structure surrounding the main body part 110. The second bonding part 14 can be a double-sided adhesive resistant to high and low temperatures, which can ensure the fixing strength of the handle, or it can be a magic tape, which can be reused and can realize the detachable of the handle 11, facilitating replacement. The second bonding part 14 is designed as an annular structure, which can block the second opening 1021 to ensure the sealing of the transport bag and realize the waterproof function.

[0044] To further improve the connection strength of the handle 11 on the second open edge 102, as Figure 3 shown, there can be multiple first bonding parts 13 and they extend in the same direction as the handle 11. The multiple first bonding parts 13 are respectively located on both sides of the handle 11. In this embodiment, both the handle 11 and the first bonding parts 13 extend along the length direction. The first bonding parts 13 are respectively provided on the upper side and the lower side of the handle 11 and cooperate with the fixing part 112 to prevent the handle 11 from disengaging from the second opening 1021.

[0045] Considering that the bag body 10 of the transport bag 1 in the present disclosure is made of a soft material, to maintain the shape of the bag body 10, in the present disclosure, as Figure 2 and Figure 4 shown, the transport bag further includes a lining 12 provided in the bag body 10. The lining 12 can be placed on the bottom wall of the bag body 10, which can strengthen the bearing effect of the transport bag 1 on the goods inside the bag and at the same time play a role in restraining and fixing the goods inside the bag. The lining 12 can be designed according to the type of goods. In an exemplary embodiment of the present disclosure, as Figure 4 shown, the lining 12 has a bottom plate 121 and a plurality of flanges 122 provided on the outer periphery of the bottom plate 121. The bottom plate 121 is used to fit with the bottom wall of the bag body 10, and the plurality of flanges 122 are turned up to form a receiving space with the bag body 10.

[0046] To reduce the occupied space of the transport bag 1, the transport bag 1 provided in the present disclosure is foldable, as Figure 3As shown, multiple creases 104 are provided on opposite side walls of the bag body 10, which can fold the transport bag 1 into a flat plate with the bottom retracted to one side of the flat plate. The multiple creases 104 include a first crease extending vertically at the middle position of the side wall, and two second creases forming a Y shape with the first crease, so that the bag body 10 can be folded in half from the middle to form a flat plate. The creases 104 also include a third crease above the second crease. The third crease is perpendicularly arranged with respect to the first crease. Through the third crease, the bottom of the bag body 10 can be folded to one side of the flat plate, especially applicable to the embodiment with a lining 12 provided at the bottom, and the lining 12 with the above structure does not affect the folding of the transport bag 1. The position of the third crease can be designed according to the height of the lining 12, which is not specifically limited in the present disclosure. Its folding process is similar to that of a clothing paper bag and will not be introduced in detail here.

[0047] As Figure 5 shown, the transport bag 1 provided by the present disclosure has a folded and stored state, does not occupy space, and can be retracted for future use. As Figure 3 shown, the transport bag 1 also has an open state, which is convenient for putting goods into the bag from the top opening; as Figure 1 shown, the transport bag also has a sealed state with the opening closed. The goods are placed inside the bag, the opening is sealed, and the handle 11 remains in a state where it can be lifted and carried away at any time. The transport bag 1 can be freely switched between these three states, and the operation method is simple.

[0048] Next, the structures of the connection mechanism 3 and the handle 11 and their cooperation methods will be introduced to successfully complete the connection action.

[0049] The present disclosure has standardized the design of the handle of the transport bag 1. As Figures 6 to 8 shown, the present disclosure provides a handle 11. A lifting hole 1101 for the lifting part to pass through is provided in the main body part 110 of the handle 11. Among them, a limiting part 111 is provided on the inner wall of the lifting hole 1101. The limiting part 111 can at least limit the lifting part in the circumferential direction and enable the lifting part to disengage from the limiting part 111 along a preset direction and withdraw from the handle 11. Here, the lifting part can be the lifting rod 32 of the connection mechanism 3 introduced below, or other structural forms of lifting structures, such as hooks, clamping arm, lifting arms, etc. The handle 11 can be the handle of the transport bag 1 introduced above.

[0050] In the standardized handle provided by the present disclosure, the hoisting part extends into the hoisting hole 1101 and is locked with the handle 11 through cooperation with the limiting part 111, so that the transport bag 1 can be stably hoisted on the hoisting part to ensure that it will not fall during the hoisting process. After being hoisted to the designated position, the hoisting part can easily disengage from the limiting part 111 and withdraw from the handle 11, and the transport bag 1 can be easily removed from the hoisting part, which can not only ensure the stability during hoisting, but also not affect the subsequent transfer process of the transport bag 1.

[0051] Correspondingly, as Figures 10 to 17 shown, the present disclosure provides an article connection mechanism 3, and the connection mechanism 3 can perform the connection action on any article. For example, the "article" here can be the handle of the transport bag 1 above. Hereinafter, the transport bag 1 with the handle 11 provided by the present disclosure will be taken as an example for detailed introduction. The connection mechanism 3 includes a seat body 31 and two parallel hoisting rods 32. The first ends of the hoisting rods 32 are installed in the seat body 31, and the second ends are used for clamping the article. A power member 34 for driving the hoisting rods 32 to move and a transmission member 35 arranged between the power member 34 and the hoisting rods 32 are provided in the seat body 31. The power member 34 drives the two hoisting rods 32 to move synchronously through the transmission member 35 to approach or separate 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 layout 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 fall within the protection scope of the present disclosure.

[0052] In the connection mechanism 3 provided by the present disclosure, the power member 34 drives the two hoisting rods 32 to move through the transmission member 35, and the distance between the two hoisting rods 32 can be automatically adjusted, so that the connection mechanism 3 can be applicable to articles of different specifications and different types. The second ends of the hoisting rods 32 can stably clamp the article, and the connection action can be accurately and reliably completed. The connection mechanism can achieve high-reliability docking with the article, realize automatic connection, the connection action is more reliable, and the operation is more convenient.

[0053] Taking the connection of the transport bag 1 with the handle 11 by using the connection mechanism 3 as an example, the second ends of the hoisting rods 32 can extend into the hoisting hole 1101 of the handle 11, and the two hoisting rods 32 can approach or separate from each other to respectively enter the limiting part 111 of the handle 11 for locking, or disengage from the limiting part 111 and withdraw from the handle 11.

[0054] A limit portion 111 is provided on the inner wall opposite to the hoisting hole 1101, and the two hoisting rods 32 are close to each other so as to be able to extend into the hoisting hole 1101, and then the two hoisting rods 32 move away from each other and enter the corresponding limit portions 111 for locking, at which time the docking mechanism 3 completes the docking action of the transport bag 1, and can drive the transport bag 1 to move, for example, when the movement is to dock with the drone and the transport bag 1 is transferred to the drone, the two hoisting rods 32 can approach each other, escape from the corresponding limit portions 111 and exit the handle 11, and complete the unlocking with the docking mechanism 3. The docking mechanism 3 can achieve high-reliability docking with the transport bag 1, realize automatic docking, and the docking action is more reliable and the operation is more convenient.

[0055] like Figure 18 As shown, the docking mechanism 3 can be installed on the robot arm 2 of the container. The movement of the robot 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.

[0056] The limiting portion 111 may be any appropriate structure, and may 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 through cooperation with the hanging rod 32. Any limiting portion that can achieve this limiting effect belongs to the protection scope of the present disclosure. In an exemplary embodiment of the present disclosure, if Figure 8 As shown, 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 circumferentially limit the hanging rod 32. 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 Figure 8 As shown, the handle 11 has two fixed arms and a connecting arm connecting the two fixed arms, and the two fixed arms and the connecting arm together form a lifting hole 1101. Here, the lifting hole 1101 can be rectangular, which is convenient for the lifting rod 32 to extend into. The positions where the two fixed arms and the connecting arm are connected are respectively provided with limiting parts 111, and the openings 1112 of the two limiting parts 111 are arranged relatively, that is, the two limiting parts 111 are respectively arranged at two opposite corner positions of the handle 11, corresponding to the two lifting rods 32 respectively. In this embodiment, the concave section 1111 can be two-thirds of a circular arc, and the remaining one-third of the circular concave section is an opening section 1112, which can be specifically designed according to the shape and shaft diameter of the lifting rod 32. One end of the opening section 1112 can be designed as a rounded corner, which is convenient for the two lifting rods 32 to withdraw from the limiting part 111 when they are close to each other, which can achieve circumferential limitation and will not affect unlocking. It should be understood that the inner concave section 1111 may also be other shapes that can play a role in circumferentially limiting the hanging rod 32 .

[0057] As Figure 8 shown, the fixing arms on both sides gradually increase in width from one end of the opening 1112 in a direction away from the connecting arm, which can play a strengthening role. At the position of the limiting portion 111, the structural strength of the handle 11 itself is increased, and at the same time, the insertion and withdrawal of the lifting rod 32 are not affected.

[0058] The limiting portion 111 is used to limit the lifting rod 32 circumferentially. Further, to achieve axial limitation and the clamping effect on the article, as Figure 10 and Figure 15 shown, a fixing block 321 and a movable block 322 are provided at the second end of the lifting rod 32. The movable block 322 can move axially to clamp the handle 11 in the gap 320 between the fixing block 321 and the movable block 322. By adjusting the position of the movable block 322 axially, 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 portion 110 of the handle 11. When the movable block 322 moves towards the fixing block 321, the clamping of the handle 11 can be achieved. When the movable block 322 moves away from the fixing block 321, the handle 11 can be unlocked. By providing the movable block 321 and the fixing block 322, the handle 11 can be stably fixed at the designated position of the lifting rod 32 and will not shake axially. Cooperating with the limiting portion 111, the stability and reliability of the hoisting of the transport bag 1 after connection are ensured.

[0059] There are various ways to adjust the position of the movable block 322 axially. For example, it can be threadedly connected to the lifting rod 32. In the present disclosure, a stop portion 323 is provided on the side of the movable block 322 on the lifting rod 32 away from the fixing block 321, and an elastic member 33 is provided between the stop portion 323 and the movable block 322. When unlocking is required, the movable block 322 moves in a direction away from the fixing block 321, compressing the elastic member 33 and increasing the gap 320. When locking is required, under the action of the restoring force of the elastic member 33, the movable block 322 automatically moves towards the fixing block 321 to perform the clamping action.

[0060] In the present disclosure, at least one of the movable block 322 and the fixing block 321 is provided with a guiding inclined surface, and the guiding inclined surface extends obliquely towards the gap 320. In Figure 10 the illustrated embodiment, only the movable block 322 is provided with a guiding inclined surface 3221. The robotic arm 2 drives the connection mechanism 3 to move into the lifting hole 1101 of the handle 11. When the robotic arm 2 extends forward excessively, even if the handle 11 is located at the position of the guiding inclined surface 3221, it can automatically slide into the gap 320 along the guiding inclined surface 3221.

[0061] In Figure 15In the illustrated embodiment, guiding inclined surfaces are respectively provided on the movable block 322 and the fixed block 321. The fixed block 321 has a conical surface and a first guiding inclined surface 3211 extending towards the gap 320, and the movable block 322 has a second guiding inclined surface 3221 extending towards the gap 320. When the handle 11 of the transport bag 1 is placed within the range of the first guiding inclined surface 3211 and the second guiding inclined surface 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.

[0062] To further enhance the connection strength at the position of the handle 11, as Figure 6 and Figure 7 shown, the handle 11 further includes a reinforcing member 114. The reinforcing member 114 is fixed on the side of the fixing portion 112 away from the main body portion 110. The reinforcing member 114 serves as the load-bearing part between the handle 11 and the bag main body 10, dispersing the weight of the goods to the reinforcing member 114 and the main body portion 110, avoiding concentrated force on the main body portion 110 and ensuring the uniformity of force.

[0063] As Figure 3 and Figure 8 shown, both ends of the reinforcing member 114 respectively extend beyond the fixing portion 112. A step portion 103 is provided at the top opening of the bag main body 10. As Figure 1 shown, in the sealed state of the transport bag 1, the reinforcing member 114 can be lapped on the side walls opposite to the opening and limited by the step portion 103, playing a role of support and limitation, and preventing the transport bag 1 from deforming during the hoisting process.

[0064] Furthermore, to enhance the structural strength of the handle 11 itself, as Figure 8 shown, at least one of the main body portion 110 and the reinforcing member 114 is provided with a plurality of reinforcing ribs 115, and the plurality of reinforcing ribs 115 are arranged at an angle to each other. In the area between the reinforcing ribs 115, a weight reduction design is carried out to reduce the weight of the handle 11 while ensuring the strength of the handle 11, which conforms to the principle of lightweight design.

[0065] As Figure 9As shown in the figure, the present disclosure has standardized the design of the handle 11. The size of the lifting hole 1101 in the length direction is D1, and the size in the height direction is D2. Among them, 80mm ≤ D1 ≤ 95mm, 30mm ≤ D2 ≤ 40mm. The size of D1 can be determined by the width of four fingers. When the user holds the transport bag 1 by hand, it is convenient to insert or withdraw the handle 11. The size of D2 needs to be designed by comprehensively considering the thickness of the fingers, the shaft diameter of the lifting rod 32, and the relevant structure of the UAV receiving end to ensure that the above structures can freely insert or withdraw from the lifting hole 1101. The maximum distance between the two lifting rods 32 in the connection mechanism 3 and the distance between the two side guiding parts 451 in the mounting mechanism 4 can be designed according to D1. The length of the reinforcing member 114 is D3, where 200mm ≤ D3 ≤ 300mm, and it can be specifically designed according to the length of the bag body 10. Through the design of the shape, size, and material of the handle 11, the handle 11 can resist an impact force of 16N.

[0066] In the present disclosure, as Figure 7 shown, a positioning hole 113 is provided at a position on the handle 11 close to the limiting part 111. As Figure 18 shown, the seat body 31 of the connection mechanism 3 can be detachably connected to the robotic arm 2 through fasteners, and the robotic arm 2 can move to drive the connection mechanism 3 to move. As Figure 16 shown, the connection mechanism 3 further includes a camera module 38 provided on the seat body 31. The camera module 38 is used to obtain the position information of the positioning hole 113 on the handle 11. By obtaining the position information of the positioning hole 113 on the handle 11 through the camera module 38 and transmitting this position information to the robotic arm 2, the movement of the robotic arm 2 is controlled, and then the relative position of the connection mechanism 3 and the handle 11 is adjusted to ensure that the lifting rod 32 can be smoothly inserted into the lifting hole 1101, thus successfully completing the connection action.

[0067] As Figure 8 shown, a plurality of positioning holes 113 are respectively provided on the fixed arms on both sides of the handle 11. Three or four positioning holes 113 can be set. The camera module 38 can quickly and accurately obtain the positions of the positioning holes 113, thereby determining the position of the handle 11. The positioning holes 113 are designed close to the limiting part 111. The positioning holes 113 can be combined with the limiting part 111. By using the limiting part 111 to determine that the obtained hole is the positioning hole 113, the position error of the positioning hole 113 is avoided, and the accuracy of visual recognition is ensured.

[0068] Furthermore, in the connection mechanism 3, there are various ways to realize the automatic approach or separation of the two lifting rods 32.

[0069] In the first exemplary embodiment of the present disclosure, as Figure 11As shown in the figure, the seat body 31 is provided with a first sliding groove 311 and a second sliding groove 312 which are parallel and arranged staggeredly. The first sliding groove 311 and the second sliding groove 312 respectively correspond to two lifting rods 32. The lifting rod 32 has a straight portion 324 located in the corresponding sliding groove and an extension portion 325 forming an angle with the straight portion 324. Compared with the embodiment of parallel arrangement, the two sliding grooves are parallel and arranged staggeredly, which can increase the distance between the two lifting rods 32 when they move away from each other, and the applicable range of the lifting holes 1101 is larger. At the same time, by arranging the angle of the extension portion 325, the two lifting rods 25 can be located in the same height direction, which is convenient for inserting into the lifting holes 1101.

[0070] In the first exemplary embodiment of the present disclosure, as Figures 12 to 14 shown, two guide rails 36 are provided in the seat body 31, and sliders 37 are respectively and slidably fitted and installed 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 respectively connected to the corresponding sliders 37. The first ends of the two lifting rods 32 are respectively connected to the corresponding racks 352. The two racks 352 are arranged in parallel and respectively meshed with the gear 351. The power member 34 can be a motor. The gear 351 is connected to the output shaft of the motor and transmits the power to the racks 352 respectively. The racks 352 on both sides respectively drive the corresponding sliders 37 to move linearly along the guide rails 36, so as to drive the two lifting rods 32 to approach or move away from each other.

[0071] In the second exemplary embodiment of the present disclosure, as Figure 15 shown, the transmission member 35 includes a moving seat 353 connected to the output shaft of the power member 34 and a multi-link mechanism 354 connected between the moving seat 353 and the first end of each lifting rod 32, that is, a multi-link mechanism 354 is respectively provided between each lifting rod 32 and the moving seat 353. The power member 34 transmits the power to the moving seat 353 and the multi-link mechanism 354 in sequence, so as to be converted into the movement of the lifting rod 32. Specifically, in this embodiment, as Figure 15 shown, the moving seat 353 includes a nut seat 3531 and hinge rods 3532 rotatably connected to both sides of the nut seat 3531. The multi-link mechanism 354 is a four-link mechanism hinged in sequence. The first end of the four-link mechanism is rotatably connected to the hinge rod 3532, and the tail end is linked to the seat body 31. The first end of the lifting 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 can be converted into the axial movement of the nut seat 3531, and then drive the hinge rod 3532 and the four-link mechanism to rotate, so as to be converted into the approach or separation of the two lifting rods 32. The transmission member 35 is not limited to the gear rack and multi-link mechanism shown in the above embodiments, and can also be a linear module, a chain mechanism, etc.

[0072] The present disclosure also provides a container, and the robotic arm 2 is movably arranged in the container, asFigure 18 As shown in the figure, a linear module 21 is provided inside the container. The container has a top opening 20. The robotic arm 2 can drive the connection mechanism 3 and the transport bag 1 to move to the top opening 20 to place the connection mechanism 3 at the top opening for docking with the incoming drone. This container has all the beneficial effects of the above-mentioned connection mechanism 3, and will not be elaborated here.

[0073] The robotic arm 2 can be composed of multiple segments that form an angle with each other to drive the connection mechanism 3 to move in different directions. On the side of the seat body 31 for connecting with the robotic arm 2, that is, the side of the seat body 31 away from the lifting rod 32, there is a reduced-diameter section 313 for avoiding interference to avoid the robotic arm 2. In the second exemplary embodiment of the present disclosure, considering the possible interference problem between the connection mechanism 3 and the robotic arm 2, as Figure 17 shown, the size of a part of the seat body 31 is reduced. For example, it is designed from a square in the first embodiment to a cylindrical shape in the second embodiment. Reducing the size of the seat body 31 conforms to the design principle of lightweight, and at the same time can effectively avoid interference and ensure that the robotic arm 2 moves in different directions.

[0074] Next, the present disclosure introduces the structure of the receiving end of the drone and the handle 11 and the cooperation method between the two.

[0075] As Figures 19 to 22 shown, the present disclosure provides a mounting mechanism 4. The mounting mechanism 4 can be installed on distribution main bodies such as drones, delivery vehicles, and robots, and can be used to mount various different types of items. Specifically, in the following text, taking the transport bag 1 with the handle 11 introduced above as an example and the mounting mechanism 4 being installed on the drone, the structure of the mounting mechanism 4 will be introduced in detail.

[0076] The mounting mechanism 4 includes a seat main body 41, a locking piece 42, and a locking tongue 43. The seat main body 41 is used for detachably installing on the fuselage of the drone; the seat main body 41 is provided with a support seat 411. The locking piece 42 is rotatably installed on the support seat 411. The locking piece 42 has a first piece 421 and a second piece 422. One end of the first piece 421 and the second piece 422 are connected to form an angle. The first piece 421 drives the second piece 422 to rotate to enclose a limiting space with a part of the top of the seat main body 41. The handle 11 of the transport bag 1 can abut against the first piece 421 and can then enter the limiting space between the first piece 421 and the second piece 422. The locking tongue 43 is movably installed on the top of the seat main body 41, and the locking tongue 43 is used to prevent or restore the rotation of the second piece 422.

[0077] The lock tongue 43 includes a shell body 431 and a tongue piece 432. The tongue piece 432 is located below the shell body 431 and is elastically connected to the shell body 431. The tongue piece 432 has a first state of extending out of the shell body 431 and a second state of at least partially retracting into the shell body 431. When the second piece 422 rotates to abut against the lock tongue 43, 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 second piece 422 rotates to a position where a limiting 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.

[0078] 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.

[0079] by Figure 26 Taking the embodiment shown in as an example, the transport bag 1 is hoisted on the docking mechanism 3, and the mechanical arm 2 drives the docking mechanism 3 and the transport bag 1 to move toward the receiving end of the drone. The handle 11 continues to move forward after contacting the first sheet 421, driving the locking piece 42 to rotate counterclockwise. When it rotates to the point where the second sheet 422 abuts against the tongue 432, the tongue 432 is compressed to partially retract into the shell 431, so that the second sheet 422 passes over the tongue 432, and the handle 11 enters the limited space formed by the first sheet 421, the second sheet 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 sheet 422, prevents the locking piece 42 from rotating, and completes the drone's receiving and locking action on the handle 11, entering. Figure 29 At this time, the robot arm 2 drives the docking mechanism 3 to move forward, compressing the elastic member 33, increasing the gap 320 between the movable block 322 and the fixed block 321, unlocking the connection between the hoisting rod 32 and the handle 11 in the axial direction, and the power member 34 drives the two hoisting rods 32 to move closer to each other, disengaging from the limit portion 111 and exiting the handle 11, transferring the transport bag 1 to the drone, and entering the state shown in the figure. Figure 27 and Figure 28 In the state shown, the drone carries the transport bag 1 to the delivery location, realizing the transfer of goods between different buildings, different containers, users and merchants.

[0080] On the contrary, the process of the drone transferring 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, thereby completing the automatic delivery process.

[0081] As Figure 23 and Figure 24 shown, the locking tongue 43 further includes a stop piece 433. The stop piece 433 is arranged on the side of the housing 431 away from the tongue piece 432 and is arranged at an interval from the tongue piece 432. The stop piece 433 is used to lock the second piece body 422 between the stop piece 433 and the locking tongue 432. The height of the stop piece 433 is configured not to affect the forward rotation of the first piece body 421, and can limit the handle 11 and the second piece body 422 when the handle 11 is located in the limit space, ensuring the fixed position of the handle 11 in the limit space. In this way, during the flight of the UAV carrying the transport bag 1, it will not affect the flight of the UAV and ensure the stability during the flight process.

[0082] When the second piece body 422 is located between the tongue piece 432 and the stop piece 433, the locking tongue 43 can move away from the locking piece 42 to release the restriction on the rotation of the tongue piece 432 on the second piece body 422. In the present disclosure, as Figure 19 shown, the handle 11 moves in the front-rear direction into the limit space. The locking tongue 43 is arranged above the locking piece 42 and can move back and forth. During the rotation of the locking piece 42 to the position forming the limit space, the front-rear position of the locking tongue 43 remains fixed. When it is necessary to release the handle 11, the locking tongue 43 moves backward, the locking piece 42 rotates in the clockwise direction, and the handle 11 automatically slides down along the second piece body 422 and the first guiding surface 4110 described below.

[0083] As Figure 22 shown, a driving member 44 for driving the locking tongue 43 to move back and forth is further provided on the seat main body 41. The driving member 44 can be a linear module or a linear motor, etc., and can drive the entire locking tongue 43 to move back and forth. In the present disclosure, as Figure 25 shown, the tongue piece 432 can extend or retract from 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, it can be unlocked when the driving member 44 fails. The locking end of the tongue piece 432 is designed as a hook-like structure, and the locking end of the second piece body 422 adopts a widened design to increase the contact area with the tongue piece 432 and ensure the reliability of the locking position.

[0084] As Figure 22 shown, the mounting mechanism 4 further includes a suction member 46 for fixing the first piece body 421. When the handle 11 is located in the limit space, the suction member 46 can be energized to suck and fix the first piece body 421 to avoid abnormal noise caused by the rotating locking piece 42. When it is necessary to release the handle 11, the suction member 46 is de-energized to release the first piece body 421.

[0085] As Figure 19 and Figure 20As shown in the figure, the seat main body 41 has a support seat 411 disposed at the middle position. The lock piece 42 is rotatably installed in the support seat 411. The support seat 411 has a first guiding surface 4110. The handle 11 can move along the first guiding surface 4110 to drive the lock piece 42 to rotate and enter the limiting space. Compared with the drone with double-ear type mounting, the present disclosure adopts the way of single handle mounting in the middle. The operation mode is simple and reliable, and the mounting success rate is high. It can solve the influence of the shaking of the transport bag 1 on the control of the drone, and can ensure the stability of the drone carrying the transport bag 1 during flight. During the process of the handle 11 moving towards the limiting space, the first guiding surface 4110 can play a guiding role. And when the locking tongue 43 releases the handle 11, the handle 11 can automatically slide down along the first guiding surface 4110 under the action of gravity, which can also play a guiding and buffering role.

[0086] As Figure 21 shown in the figure, the mounting mechanism 4 provided by the present disclosure further includes a connecting seat 45 connected to the seat main body 41. The connecting seat 45 has a main body part connected to the seat main body and a guiding part 451 located outside the main body part. The two sides of the support seat 411 are respectively provided with guiding parts 451, and the guiding parts 451 on both sides have inclined second guiding surfaces 4510 that gradually approach each other inward. As Figure 26 shown in the figure, when the connection mechanism 3 carrying the transport bag 1 moves towards the mounting mechanism 4, as Figure 29 shown in the figure, the second guiding surfaces 4510 on both sides are used to guide the connection mechanism 3 suspending the transport bag 1 to move towards the direction of the support seat 411, so as to quickly find the position of the lock piece 42 and ensure the smooth and rapid completion of the handover action.

[0087] As Figure 27 shown in the figure, the distance between the guiding parts 451 on both sides is greater than the dimension D1 of the handle 11 in the length direction. The handle 11 can be located in the space between the guiding parts 451 on both sides to perform the receiving action with the drone receiving end.

[0088] The present disclosure further provides a drone, and the mounting mechanism described above is provided on the fuselage of the drone. The mounting mechanism 4 is detachably installed on the fuselage of the drone. This drone has all the beneficial effects of the drone mounting mechanism 4, which will not be elaborated here. Of course, the mounting mechanism 4 can also be installed at any position where it is necessary to mount the transport bag 1, such as an airplane, a car, etc., and the present disclosure does not make a limitation.

[0089] Next, the present disclosure provides a cargo delivery system, as Figure 29As shown in the figure, it includes the transport bag 1, the goods connection mechanism 3, and the drone mounting mechanism 4 introduced above. The transport bag 1 with the handle 11 can be transferred between the goods connection mechanism 3 and the drone mounting mechanism 4. For example, it can be used for delivery between users and merchants. The merchant places the packaged meal bag in the storage position of the cabinet. After receiving the delivery instruction, the robotic arm 2 drives the connection mechanism 3 to move to this storage position (obtaining the position of the positioning hole 113 on the handle 11 through the camera module 38 to determine whether the movement is in place). The two lifting rods 32 of the connection mechanism 3 extend into the lifting holes 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 through the movable block 322 and the fixed block 321, completing the connection action of the connection mechanism 3 to the meal bag; the robotic arm 2 drives the connection mechanism 3 and the meal bag to move to the opening at the top of the cabinet and dock with the incoming drone on the top takeoff and landing platform. During this process, the second guiding surface 4510 can play a guiding role to move to the position of the support seat 411. The robotic arm 2 continues to drive the connection mechanism 3 and the meal bag to move forward. The handle 11 abuts against the first sheet body 421, driving the second sheet body 422 to rotate. The second sheet body 422 compresses and crosses the tongue piece 432, and the handle 11 enters the limiting space between the first sheet body 421 and the second sheet body 422. The tongue piece 432 extends out of the housing 431 to stop the second sheet body 422, realizing the locking of the handle 11 and completing the receiving action of the drone mounting mechanism 4 for the meal bag; at this time, the connection mechanism 3 moves forward, compressing the elastic member 33, and the distance between the movable block 322 and the fixed block 321 increases. The lifting rods 32 can disengage from the limiting parts 111, and the two lifting rods 32 approach each other and withdraw from the handle, completing the transfer action. At this time, the drone can carry the meal bag and fly to the delivery location. The locking tongue 43 moves backward to open the locking piece 42, and the handle 11 automatically slides down along the first guiding surface 4110 to complete the delivery process.

[0090] Of course, the drone can also transfer the meal bag to the connection mechanism in the meal cabinet in the user's community, so as to store the meal bag in the designated storage position of the meal cabinet for the user to pick up by himself. This goods delivery system has all the beneficial effects of the above-mentioned handle 11, transport bag 1, connection mechanism 3, and mounting mechanism 4, and will not be repeated here. This goods delivery system can complete the automatic delivery process of goods, can not only achieve automatic connection of goods, with more reliable connection actions and simple structures; but also can improve the loading rate of goods, ensure loading reliability, avoid the influence of the shaking of the meal box on the control of the drone, and enhance the user experience; through the standardized design of the handle 11, it can meet the requirements of both the connection mechanism 3 and the mounting mechanism 4 at the same time. The transport bag 1 has good mass production performance, is simple to process, light in weight, low in cost, small in volume, and reusable, and can meet the delivery requirements of different goods in the drone delivery scenario.
