Through the above technical solution, in the cargo transceiving process, the transceiving platform 310 of the cargo transceiving device 300 moves and transfers the cargo 400 between the loading and unloading port (not shown in the figure) and the inner side of the cargo window 110 through the rail mechanism 200, and when the transceiving platform 310 moves to the cargo window 110, the cargo 400 can be transferred between the transceiving platform 310 and the cargo window 110 through the transfer mechanism 320, so as to load the cargo 400 to the unmanned aerial vehicle or unload the cargo 400 from the unmanned aerial vehicle to the corresponding cargo window 110. For example, when the goods are delivered through the distribution cabinet, the goods transceiver 300 may receive the goods 400 at the goods window 110, that is, the goods 400 are transported from the goods window 110 to the transceiving platform 310 through the transporting mechanism 320, the transceiving platform 310 then moves to the loading/unloading port with the goods 400 through the track mechanism 200, and the unmanned aerial vehicle picks up the goods from the transceiving platform 310 to complete the delivery process; when goods are received through the distribution cabinet, the receiving and dispatching platform 310 receives the goods 400 conveyed by the unmanned aerial vehicle from the loading and unloading opening, then moves to the corresponding goods window 110 through the rail mechanism 200, and transports the goods 400 from the receiving and dispatching platform 310 to the goods window 110 through the transport mechanism 320, thereby completing the goods receiving process. In this way, the cargo is only required to be transported between the transceiving platform 310 and the cargo window 110, and the cargo transfer is not required to be performed in the cabinet 100, so that the cargo transfer process is smoother, the loading and unloading speed is obviously increased, meanwhile, the arrangement of a redundant mechanism for cargo transfer, for example, can be reduced, the manufacturing cost can be reduced, and the occupied space of the redundant mechanism can be reduced.

The goods 400 may be the goods to be transported, such as couriers, etc., or may be containers loaded with goods, etc., and the disclosure is not limited thereto.

In addition, above-mentioned unmanned aerial vehicle can be the unmanned aerial vehicle that has the cargo hold, is used for transporting the arbitrary model of goods, can select for use different loads, the unmanned aerial vehicle of different cargo hold capacity according to transporting the goods size, correspondingly, receiving and dispatching platform 310, transport mechanism 320 and goods window 110 can design according to unmanned aerial vehicle's model and goods size adaptability to use in the commodity circulation scene of difference, this disclosure does not do specific restriction to this.

In addition, the above-mentioned unmanned aerial vehicle may have a built-in or external cargo hold, and a locking mechanism for fixing the cargo may be provided in the cargo hold to prevent the cargo from falling or moving (e.g., shaking or swinging) during transportation. The locking mechanism may be an electric buckle, an automatic door opening and closing mechanism, etc., and may automatically lock the cargo when the cargo is transferred into the cargo compartment, and automatically release the cargo when the cargo is unloaded, so that the cargo is unloaded from the cargo compartment.

A plurality of cargo windows 110 may be arranged on at least one side of the cabinet 100 to increase the storage capacity of the cabinet 100 through the plurality of cargo windows 110, and in addition, the cabinet 100 is further provided with a manual interaction window for information interaction between the system and the user.

Wherein, the outer side of the goods window 110 is further provided with a cabinet door for opening or closing the goods window 110; the cargo window 110 is provided therein with a sensor for detecting whether the cargo window 110 has cargo and serving as a number for each cargo window 110. The cargo window 110 which is the highest in the longitudinal direction and the closest to the loading and unloading port in the transverse direction has the highest priority level, the cargo docking equipment can preferentially select the cargo window 110 to place the cargo 400 in the loading or unloading process, and according to the logical selection mode, the driving distance of the track mechanism 200 to the cargo transceiving device 300 is the smallest, so that the cost can be reduced to the maximum extent, and the efficiency can be improved.

Further, the landing platform 600 may include a top cover disposed above the cabinet 100 and having a first cover door and a second cover door, and an actuating device actuating the first cover door and the second cover door to move toward each other to close the loading/unloading opening; the actuating device actuates the first cover door and the second cover door to move oppositely so as to expose the parking area and the loading and unloading opening on the parking area. During the process of loading or unloading the cargo 400, the actuating device drives the first cover door and the second cover door to move away from each other, so as to expose the parking area in advance, thereby facilitating the parking of the unmanned aerial vehicle.

After the unmanned aerial vehicle puts the goods 400 on the receiving and dispatching platform 310 through the loading and unloading port, the placing position of the goods 400 is shifted due to the difference of the parking positions of the unmanned aerial vehicle or the difference of the sizes of the goods 400 or the shift of the dropping process of the goods 400, so that the goods 400 are not accurately placed in the goods window 110. Thus, in some embodiments, referring to fig. 2 and 5, the cargo docking apparatus includes a base 330 movably disposed on the rail mechanism 200, the carrying mechanism 320 is disposed on the base 330 and includes a second driving device and a clamping device, the clamping device includes two clamping structures 321 capable of moving relatively in a lateral direction to clamp or release the cargo 400, and the second driving device is used for moving the clamping device between the transceiving platform 310 and the cargo window 110. In this way, the two clamping structures 321 can clamp and position the goods 400 simultaneously in the process of clamping the goods 400, that is, the goods 400 can be positioned in the transverse direction, so that the goods 400 can be accurately sent into the corresponding goods windows 110. The clamping and positioning process may be performed in synchronization with the movement of the cargo-receiving device 300 on the track mechanism 200 to further increase the speed of the cargo 400 being transported within the cabinet 100.

The clamping device may achieve the relative movement of the two clamping structures 321 in any suitable manner, for example, as shown in fig. 5 and 8, the clamping device further includes a first mounting plate 322 connected to the output end of the second driving device and a third driving device disposed on the first mounting plate 322, the third driving device is used for driving the two clamping structures 321 to approach or separate from each other, the two clamping structures 321 are arranged at intervals along the transverse direction and each include a first plate 3211 and a second plate 3212 in an L shape, the two first plates 3211 are connected to the third driving device, and the two second plates 3212 are used for clamping the cargo 400 therebetween. In this way, the first mounting plate 322 may be driven to move by the second driving device to drive the clamping device to move, and the two clamping structures 321 may be driven to approach or separate from each other by the third driving device to clamp or release the cargo 400. Wherein, all be provided with the slipmat on the relative side of two second boards 3212 to be used for increasing the frictional force with goods 400, prevent that goods 400 from dropping.

The third driving device may be arranged in any suitable manner according to the requirements of the actual application, and the purpose of the third driving device is to drive the two clamping structures 321 to move relatively. For example, in some embodiments, referring to fig. 8, the third driving device may include a third motor 323 and a third transmission mechanism, and the third motor 323 drives the two clamping structures 321 to approach or move away from each other through the third transmission mechanism.

The third transmission mechanism may be configured in any suitable manner, for example, the third transmission mechanism may include two second pulleys 324 and two second timing belts 325, the two second pulleys 324 are spaced apart in the transverse direction and are rotatably mounted on the first mounting plate 322, the second timing belts 325 are wound around the two second pulleys 324, the output end of the third motor 323 is drivingly connected to any one of the second pulleys 324, one of the two first plates 3211 is connected to one belt body of the second timing belts 325, and the other is connected to the other belt body of the second timing belts 325. Thus, when the second timing belt 325 is rotated by the third motor 323, the two holding structures 321 are moved toward or away from each other.

In order to increase the stability of the two clamping structures 321 when relatively moving and clamping the goods 400, in some embodiments, the clamping device further comprises a second guiding structure for guiding the two clamping structures 321 to relatively move in the lateral direction. Referring to fig. 8, the second guiding structure may include a second sliding rail 3221 and a first sliding block, which are slidably engaged with each other, the second sliding rail 3221 is disposed on the first mounting plate 322 and extends laterally, and the number of the first sliding blocks is two and is disposed on the two first plates 3211, respectively. In this way, the sliding fit between the second slide rail 3221 and the two first sliders can guide the two clamping structures 321 to move laterally relative to each other, so that the stability of the two clamping structures 321 when moving and the stability of the goods 400 when clamping can be increased.

To facilitate the transfer mechanism 320 to transfer cargo between the transceiving platform 310 and the cargo window 110, in some embodiments, referring to fig. 5, the transceiving platform 310 can be moved to horizontally interface with the cargo window 110, the second driving device is disposed on the second mounting plate 370 attached to the base 330 and comprises a second motor 326 and a second transmission mechanism, and the second motor 326 drives the clamping device to move along a lateral direction through the second transmission mechanism, wherein the lateral direction and the lateral direction are perpendicular to each other and are both parallel to a horizontal plane. In this way, the carrying mechanism 320 carries the cargo 400 in the lateral direction parallel to the horizontal plane, and the structure of the carrying mechanism 320 can be simplified, and the occupied space and weight can be reduced.

The second transmission mechanism of the second driving device may be configured in any suitable manner, for example, in some embodiments, as shown in fig. 5 to 8, the second transmission mechanism includes a first pulley 327, a first synchronous belt 328 and a second guide rod 329, the number of the first pulleys 327 is two, the two first pulleys 327 are spaced apart in the lateral direction and are respectively rotatably mounted on the second mounting plate 370, the first synchronous belt 328 is wound around the two first pulleys 327, the output end of the second motor 326 is in driving connection with any one of the first pulleys 327, the second guide rod 329 is movably disposed on the base 330 in the lateral direction, and one end of the second guide rod 329 is fixed to the first synchronous belt 328, and the other end is fixed to the first mounting plate 322. Thus, the second motor 326 rotates the first timing belt 328, which in turn moves the second guide bar 329 in the lateral direction, to drive the first mounting plate 322 of the clamping device in the lateral direction. The second motor 326 may be a stepping motor or a servo motor, so as to precisely control the moving distance of the clamping device in the lateral direction, so that the clamping device can precisely extend into the cargo window 110 to clamp or release the cargo 400. In other embodiments, the second transmission mechanism may also drive the clamping device to move laterally in a screw transmission or gear transmission manner, and the disclosure is not limited thereto.

The base 330 is configured in an L-shaped structure, and can reduce the occupied space and the weight while providing support for the carrying mechanism 320 and the transceiving platform 310. Wherein the number of the second guide bars 329 is at least two in parallel, and one of the second guide bars 329 is connected to the first timing belt 328 for driving the movement of the clamping means. By providing at least two second guide bars 329, the stability of the clamping device when moving in a lateral direction can be enhanced.
