Detailed Implementation

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention and therefore only show the components relevant to the present invention.

[0024] It should be noted that if directional indicators (such as up, down, bottom, top, etc.) are involved in the embodiments of the present invention, these directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" and "second" may explicitly or implicitly include one or more of that feature. Unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in the present invention can be understood according to the specific circumstances. Example 1

[0025] A cargo drone storage and loading system includes: a drone cargo box 1 and a storage and retrieval drawer 2 that is laterally inserted into the drone cargo box 1.

[0026] Specifically, the drone cargo box 1 includes a box body 11, and a receiving cavity 12 is provided inside the box body 11. One side of the box body 11 is the cargo loading and unloading side, and the cargo loading and unloading side is provided with an inlet and outlet that communicates with the receiving cavity 12. Specifically, the storage drawer 2 includes a receiving housing 21 that can be inserted into the receiving cavity 12. The receiving housing 21 is provided with a receiving area for receiving goods. Several locking tongue components are provided between the receiving housing 21 and the drone cargo box 1 to realize assembly and release.

[0027] Specifically, the latch assembly includes a second latch 26 disposed on the storage drawer 2, and the second latch 26 can extend and retract relative to a preset lock hole on the housing 11 to achieve docking and release between the second latch 26 and the lock hole on the housing 11. The latch assembly also includes a first latch 13 disposed on the housing 11, and the first latch 13 can extend and retract relative to a preset lock hole on the storage drawer 2 to achieve docking and release between the first latch 13 and the lock hole on the panel 22. Example 2

[0028] A cargo drone storage and loading system includes: a drone cargo box 1 and a storage and retrieval drawer 2 that is laterally inserted into the drone cargo box 1.

[0029] Specifically, the drone cargo box 1 includes a box body 11, and a receiving cavity 12 is provided inside the box body 11. One side of the box body 11 is the cargo loading and unloading side, and the cargo loading and unloading side is provided with an inlet and outlet that communicates with the receiving cavity 12. Specifically, the storage drawer 2 includes a receiving housing 21 that can be inserted into the receiving cavity 12. The receiving housing 21 is provided with a receiving area for receiving goods. Several locking tongue components are provided between the receiving housing 21 and the drone cargo box 1 to realize assembly and release.

[0030] Specifically, the latch assembly includes a second latch 26 mounted on the storage drawer 2, which can extend and retract relative to a pre-set lock hole on the housing 11, enabling engagement and release between the latch 26 and the lock hole on the housing 11. The latch assembly also includes a second unlock button 23 mounted on the panel 22, which is connected to the second latch 26 and controls the extension and retraction of the latch 26 relative to the pre-set lock hole on the panel 22. The latch assembly also includes a first latch 13 mounted on the housing 11, which can extend and retract relative to a pre-set lock hole on the storage drawer 2, enabling engagement and release between the latch 13 and the lock hole on the panel 22.

[0031] Furthermore, the latch assembly utilizes existing technology. For example, the control between unlock button 23 and latch 26 employs a push-button electromagnetic latch, with elastic elements laterally spaced between latch 26 and the storage drawer 2. When de-energized, latch 26 extends laterally outward due to the elasticity of the elements. When unlock button 23 is pressed, the circuit of the electromagnet of latch 26 is activated, causing latch 26 to retract laterally under electromagnetic attraction, thus unlocking the device. The control between unlock button 16 and latch 13 also utilizes a push-button electromagnetic latch, with elastic elements laterally spaced between latch 13 and the housing 11. When de-energized, latch 13 extends laterally outward due to the elasticity of the elements. When unlock button 16 is pressed, the circuit of the electromagnet of latch 13 is activated, causing latch 13 to retract laterally under electromagnetic attraction, thus unlocking the device. The specific assembly and installation structure adopts the assembly and connection relationships of existing technologies, and the specific structural components and assembly and connection relationships will not be described in detail here. The key is to achieve locking and unlocking between the horizontal container 11 and the storage / retrieval drawer 2. A double-sided control multi-latch assembly structure is designed. There is an unlocking button 16 on the bottom of the drone cargo container 1, which controls the two locking latches 13 of the drone cargo container 1. An unlocking button 23 on the storage / retrieval drawer 2 controls the locking latch 26 on the retrieval drawer 2. This improves the convenience of retrieval and the stability of transportation. Example 3

[0032] Based on Embodiment 1 or Embodiment 2, the receiving housing 21 adopts a box structure with an open top. The open top structure is a semi-enclosed storage cavity, which is convenient for extraction and allows goods to be taken out from above. Example 4

The positioning and locking are achieved by the locking tongue assembly set between the storage drawer 2 and the drone cargo box 1. When it is necessary to retrieve the goods, the retrieval drawer 2 is pulled outward relative to the drone cargo box 1 by separating the locking tongue assembly. When the cargo compartment 25 of the retrieval drawer 2 is outside the receiving cavity 12, the retrieval operation can be realized. Example 11

[0040] Based on Example 11, the drone carrying the drone cargo box 1 flies above the handling robot 4. The drone's legs are positioned between the clamping and limiting rods 42 on the handling robot 4, and the drone cargo box 1 is located on the lifting seat 43 on the handling robot 4.
