[0002] The most basic function of a drone cargo hold is to transport all kinds of goods. Through the drone's flying ability, the cargo hold can deliver the goods to the destination quickly and efficiently. Especially in remote areas or places that are difficult to reach by traditional transportation methods, the transportation capacity of the drone cargo hold is particularly important.

[0003] A Chinese patent discloses a cargo hold for drones (publication number CN210027933U), which includes a bottom plate and side plates arranged in the circumferential direction of the bottom plate, and both the bottom plate and the side plates are grid-shaped structures, and both the bottom plate and the side plates are made of aluminum alloy. According to the technical solution provided in the embodiment of the present application, by using aluminum alloy materials to prepare a cargo hold for drone transportation, the cargo hold can effectively resist aging while meeting the strength requirements of the cargo hold, thereby increasing the service life of the cargo hold.

[0004] Therefore, based on the above search and in combination with the existing ones, when the above device is in use, the cargo hold needs to shut down the drone before the device can be connected to the drone manually. However, during use, opening and closing the drone multiple times will not only cause wear and tear on the internal components of the drone and affect the life of the drone. After shutting down the drone, the staff not only needs to restart it after completing the operation, but also needs to recalibrate the drone's system and initialize the sensor again, which not only prolongs the operation time, but may also affect the efficiency of the entire workflow.
