Description

TECHNICAL FIELD The present application relates to the field of aerial vehicle technologies, and in particular, to a wing detachment assembly and an aerial vehicle. BACKGROUND An aerial vehicle may provide people with entertainment or may perform a task for people. For example, the aerial vehicle may be used as an important tool for high-altitude photography. Generally, the aerial vehicle includes a wing and a vehicle body. The aerial vehicle may occupy a relatively large space due to such a relatively long wing. Accordingly, an aerial vehicle having a detachable wing has emerged. However, an existing solution for detaching and mounting the wing of the aerial vehicle is relatively inconvenient and requires a dedicated detachment tool. Therefore, how to provide a solution for conveniently detaching and mounting the wing of the aerial vehicle has become a technical requirement in the related art. In the related art, a conventional wing detachment assembly is disclosed in the following patent documents, for example, the patent application Pub. No. DE2531388Al, the patent application Pub. No. CN109572991A, the patent application Pub. No. US2011315820Al, the patent application Pub. No. CN105366025A, and the patent application Pub. No. CN208963299U. SUMMARY The present application is mainly intended to provide a wing detachment assembly and an aerial vehicle, to resolve an existing technical problem that a solution for detaching and mounting a wing of an aerial vehicle is relatively inconvenient. According to a first aspect, the present application provides an aerial vehicle comprising a vehicle body, a wing, and a wing detachment assembly, the wing detachment assembly is configured to detachably connect the wing to the vehicle body. The wing detachment assembly includes a first connecting portion and a second connecting portion, one of the first connecting portion and the second connecting portion configured for being fixed on the wing and the other configured for being fixed on the vehicle body. The second connecting portion includes a thumb wheel, the thumb wheel being provided with a threaded hole and configured for being rotatably mounted on the vehicle body or the wing; The first connecting portion is threadedly connected to the threaded hole of the thumb wheel, the first connecting portion and the thumb wheel being fastened or detached when the thumb wheel is rotated. The wing is detachably connected to the vehicle body by using the wing detachment assembly and a part of the thumb wheel protruding out of the vehicle body or the wing to which the thumb wheel is fixed. Preferably, the thumb wheel is disc-shaped, an edge of the thumb wheel is roughly configured and a center of the thumb wheel is provided with the threaded hole, the threaded hole being a through hole. Preferably, the second connecting portion further includes a blocking member fixedly connected to one side of the thumb wheel. Preferably, the blocking member is cylindrical and is provided with a center hole, the center hole being concentric to the threaded hole. Preferably, a diameter of the center hole is greater than or equal to a diameter of the threaded hole, a thread being disposed on a hole wall of the center hole. Preferably, the first connecting portion includes a threaded post, the threaded post configured for being fixed on the wing or the vehicle body and being threadedly connected to the threaded hole. Preferably, the first connecting portion further includes a connecting plate, the connecting plate being fixedly connected to the threaded post and configured for being fixed on the vehicle body or the wing. Preferably, the connecting plate is configured for being fixed on an inner wall of a housing of the vehicle body or the wing and the threaded post passes through the housing of the vehicle body or the wing to be threadedly connected to the thumb wheel. Preferably, the threaded post includes a bolt and a fixing block, the bolt being fixedly connected to the fixing block, and the connecting plate is provided with a fixing hole, the fixing block being fixed in the fixing hole and the fixing hole limiting the fixing block in rotating. Compared with existing technologies, in the present application, the second connecting portion includes a thumb wheel, the thumb wheel being provided with a threaded hole and being rotatably mounted on the vehicle body or the wing. The first connecting portion is threadedly connected to a threaded hole of the thumb wheel, the first connecting portion and the thumb wheel being fastened or detached when the thumb wheel is rotated. In this way, the wing can be quickly mounted on the vehicle body and the wing can also be quickly detached from the vehicle body without using a dedicated detachment tool, which is easy to manually detach and mount.
