In a specific implementation mode, the first flying assembly and the second flying assembly are both provided with guide groove bodies and guide protrusions, and when the first flying assembly and the second flying assembly need to be in butt joint, the guide groove bodies and the guide protrusions which are closest to each other on the first flying assembly and the second flying assembly are in butt joint.

Wherein, the protruding butt joint of direction cell body and the direction that is closest on first flight subassembly and the second flight subassembly indicates, can realize the direction cell body and the direction arch of butt joint apart from nearest in first flight subassembly and the second flight subassembly both, wherein can artificial observation apart from nearest, perhaps through at the direction cell body with the protruding distance detector that sets up and can detect both distances of direction, and then realize the protruding butt joint of direction cell body and the direction that is closest.

The present application provides an aerial device, comprising:

such as any of the docking assemblies described above.

The first flight assembly is provided with at least one first butt joint body 1, and specifically, the first flight assembly can be provided with two or at least three first butt joint bodies 1. In particular, the first docking body 1 may be part of a first flight assembly housing.

The second flight assembly is provided with at least one second butt joint body 2, and specifically, the second flight assembly can be provided with two or at least three second butt joint bodies 1. In particular, the second docking body 2 may be part of a second flying assembly housing.

The foregoing describes a specific structure of the docking device, and the present application includes the docking device described above, and also has the technical effects described above.

In the description of the present application, it is to be understood that the orientation or positional relationship indicated by the orientation words such as "front, back, up, down, left, right", "top and bottom", etc., are usually based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplicity of description, and in the case of not being described to the contrary, these orientation words do not indicate and imply that the device or element being referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore, should not be considered as limiting the scope of the present application; the terms "inner and outer" refer to the inner and outer relative to the profile of the respective component itself.

Spatially relative terms, such as "above … …," "above … …," "above … …," "above," and the like, may be used herein for ease of description to describe one device or feature's spatial relationship to another device or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures.

It should be noted that the terms "first", "second", and the like are used to define the components, and are used to distinguish one element from another element without order or importance. .

The embodiments in the present description are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
