Title:
HANDHELD UNDERWATER FLYING VEHICLE
Document Type and Number:
WIPO Patent Application WO/2020/082440
Kind Code:
A1
Abstract:
A handheld underwater flying vehicle, comprising a battery compartment (12) and propellers. The quantity of the propellers is at least two, and the propellers are symmetrically arranged on two sides of the battery compartment (12) and connected to the battery compartment (12). The axis of the propellers and the axis of the battery compartment (12) have a special non-parallel design. The angle of the non-parallelism causes the component forces produced by the propellers not in the movement direction of the underwater flying vehicle to cancel each other out, and causes the motion of the underwater flying vehicle to remain balanced, allowing for travel in a straight line. The non-parallel design of the propeller axes and the battery compartment (12) axis causes a very small power loss, but avoids a greater power loss caused by water flow striking a person's body, improving forward thrust of the underwater flying vehicle overall during use. Because water does not strike the user's face, the user is also prevented from choking on water, making the user more comfortable and safe, and improving the overall use experience.
