In the prior art, when the unmanned aerial vehicle delivers the express through the container, the cargo is easy to incline in the container during the movement or collide with the side wall of the container due to the fact that the movement of the unmanned aerial vehicle is more complex, so that some fragile objects are damaged, and the success rate of the express delivery of the unmanned aerial vehicle cannot be guaranteed. To this end, as shown in fig. 1 and 2, an embodiment of the present invention discloses an unmanned aerial vehicle cargo delivery device 10 including a body 100, a cargo assembly 200, and a cargo box 300.

Preferably, in the present embodiment, the unmanned aerial vehicle is provided with 4 propellers 120 along the body circumferential side edge of the stand 110. Those skilled in the art may design according to practical situations and specific requirements, and the embodiment is not limited thereto.

More specifically, the connecting portion 111 is a columnar structure extending along the height direction a, the connecting portion 111 may be connected to the cargo carrying assembly 200 through a detachable connection commonly used in the art, such as a clamping connection, a screwing connection or a pin connection, preferably, in this embodiment, an external thread is disposed on the connecting portion 111, a blind hole is disposed at a position corresponding to the top of the housing 210 of the cargo carrying assembly 200, an internal thread is disposed on an inner side wall of the blind hole, and the connecting portion 111 is connected to the housing 210 through a thread. Those skilled in the art may design according to practical situations and specific requirements, and the embodiment is not limited thereto.

More specifically, as shown in fig. 1, the cargo assembly 200 includes a housing 210, a plurality of floating clamp members 220, and an unloading member 230, the top of the housing 210 is detachably connected to the connection portion 111, and the bottom of the housing 210 is provided with an out-of-cabin portion 240.

More specifically, the plurality of floating clamping members 220 are disposed on the inner sidewall of the housing 210 at intervals along the circumferential direction of the housing 210 and are located on the circumferential side of the cargo box 300 in the direction perpendicular to the height of the housing 210, and the plurality of floating clamping members 220 can clamp the cargo box 300 in the direction perpendicular to the height of the housing 210. It should be noted that 2, 3, 4 or 5 floating clamping members 220 may be disposed on the inner sidewall of the housing 210 at intervals along the circumferential direction of the housing 210, and preferably, in this embodiment, 4 floating clamping members 220 are disposed on the inner sidewall of the housing 210 at intervals along the circumferential direction of the housing 210, and an included angle between two adjacent 2 floating clamping members 220 is 90 °.

When the housing 210 is tilted, the liquid flows to the tilted side, causing the hydraulic pressure applied to the clamping blocks 223 on both sides to change, thereby aligning the cargo box 300. The response speed of the hydraulic line 212 is related to the viscosity of the fluid in the line, and the viscosity of the fluid refers to the property of preventing the fluid from moving relatively due to the internal friction generated between the micro-clusters or the fluid layers in the fluid due to the relative movement.
