Description

Technical Field

[0001] This invention relates to the field of ship propulsion and hydrofoil structure technology, specifically to an integrated hydrofoil electric propulsion unit that integrates lifting, folding, selectable angle adjustment and electric propulsion. Background Technology

[0002] Traditional integrated hydrofoil propulsion units have a simple structure, and the hydrofoil panels can only be installed at a fixed angle, which cannot be adjusted in real time according to the navigation environment; or they can only use an adjustable angle structure, which cannot meet the needs of low-cost and simplified assembly. At the same time, the lifting and folding methods are fixed, lacking a variety of optional structures, resulting in poor versatility and difficulty in adapting to hydrofoil products of different levels and different usage scenarios. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides an integrated hydrofoil electric propulsion unit. The hydrofoil can be flexibly configured with either a fixed angle or an adjustable hinged angle. The lifting and folding methods can be either gear and rack or hydraulic rotary folding. The adjustable angle hydrofoil, combined with an AI intelligent system, enables fully automatic coordinated adjustment of height and angle of attack. The modular integrated design offers excellent adaptability.

[0004] The present invention adopts the following technical solution:

[0005] An integrated hydrofoil electric propulsion unit includes a drive motor, a lifting column, hydrofoils, and a propeller propulsion mechanism. The lifting column is equipped with a lifting and folding mechanism, which can be selected from either a rack and pinion lifting mechanism or a hydraulic rotary folding lifting mechanism depending on the application scenario. The rack and pinion structure offers high adjustment precision and reliable locking, while the hydraulic rotary folding structure provides flexible storage and rapid operation. The two methods can be flexibly switched between.

[0006] The hydrofoil is configured with two optional structures. The first is a fixed-angle installation structure, which is simple and lower in cost, and is suitable for conventional fixed-condition navigation. The second is a hinged adjustable-angle installation structure. The adjustable-angle hydrofoil is equipped with an AI intelligent control system, which can automatically and collaboratively adjust the tilt angle of attack of the hydrofoil and the overall lifting height of the lifting column according to the water environment, navigation attitude, and speed data, and is suitable for high-speed navigation in complex waters.

[0007] The propeller propulsion mechanism is directly integrated into the lower end of the column, forming an integrated independent module with the hydrofoil. It can be installed at any position on the hull to quickly form hydrofoil boat systems with various layouts such as one front and two rear, two front and two rear, and four hydrofoils.

[0008] Furthermore, the propeller can be a single propeller, a coaxial twin propeller, or a multi-propeller type to adapt to different power requirements; the overall structure can be rotated and folded backward for storage, suitable for navigation in shallow water and docking at the shore, effectively protecting the propulsion and hydrofoil structure.

[0009] Beneficial effects

[0010] 1. Hydrofoils can be flexibly selected from two structures: fixed angle or hinged adjustable angle, which are suitable for low-cost conventional boats and intelligent high-speed boats, and have a wider product coverage.

[0011] 2. Flexible lifting and folding options are available, including precise lifting with a rack and pinion mechanism or quick storage with hydraulic rotation and folding, making it suitable for a wider range of scenarios.

[0012] 3. The adjustable-angle hydrofoil, combined with an AI intelligent system, enables fully automatic coordinated adjustment of altitude and angle of attack, significantly improving flight stability and environmental adaptability.

[0013] 4. The hydrofoil, lifting and folding mechanism, and propulsion system are highly integrated and modular, allowing for independent assembly, strong versatility, and easy mass production assembly and subsequent maintenance. Attached Figure Description
