Illustratively, the rudder surface motor 310 as a driving mechanism of the rudder surface 400 can drive the left and right swing position of the rudder surface 400, so as to realize the heading control effect of the rudder surface 400.

Illustratively, the control surface control mechanism 300 further includes a speed reducer 320, and the speed reducer 320 is electrically connected to the control surface motor 310 and the control surface 400, respectively.

Illustratively, in the sliding process of the electric hydrofoil body 100, the resistance of the control surface 400 is large, and the output torque of the control surface motor 310 can be increased through the transmission of the reducer 320, so that the control surface motor 310 can adopt a servo motor with a small volume, the problem of size limitation of a direct-drive scheme motor is effectively solved, and the reliability and the control precision of the control surface control mechanism 300 can be improved through the use of the reducer 320.

The reducer 320 is an independent component composed of a gear drive, a worm drive, and a gear-worm drive enclosed in a rigid housing, and is a reduction transmission device commonly used between a prime mover and a working machine, which is also called a reducer.

For example, a speed reducer is generally used for low-speed and high-torque transmission equipment, and a motor, an internal combustion engine or other high-speed running power is meshed with a large gear on an output shaft through a gear with a small number of teeth on an input shaft of the speed reducer to achieve the purpose of speed reduction.

Typically, a speed reducer acts to match rotational speed and transfer torque between a prime mover and a work machine or actuator, and is a relatively delicate machine. Its purpose is to reduce the speed and increase the torque. It has various types, different models and different purposes.

The reducer 320 provided by the embodiment of the application can be selected from different types according to requirements, and is not limited herein; for example, the reducer 320 may be selected from a gear reducer, a worm reducer, and a planetary gear reducer according to the type of transmission; single-stage and multi-stage speed reducers can be selected according to different transmission stages; according to the shape of the gear, a cylindrical gear reducer, a conical gear reducer and a conical-cylindrical gear reducer can be selected; the expanded speed reducer, the split speed reducer and the coaxial speed reducer can be selected according to the arrangement form of transmission.

An encoder (encoder) is illustratively a device that compiles, converts, and formats signals (e.g., bitstreams) or data into a form of signals that can be communicated, transmitted, and stored. Encoders convert angular or linear displacements, called codewheels, into electrical signals, called coderulers. The encoder can be divided into a contact type and a non-contact type according to a reading mode; encoders can be classified into an incremental type and an absolute type according to their operation principles. The incremental encoder converts displacement into periodic electrical signals, and then converts the electrical signals into counting pulses, and the number of the pulses is used for expressing the magnitude of the displacement. Each position of the absolute encoder corresponds to a certain digital code, so that its representation is only dependent on the start and end positions of the measurement, and not on the intermediate course of the measurement.

Illustratively, the control surface motor 310 adopts a servo motor, and the output torque of the servo motor can be increased by the cooperation of the servo motor and the transmission of the speed reducer 320, so that the problem of size limitation of a direct-drive motor can be effectively solved.

For example, the servo motor can control speed, position precision is very accurate, and voltage signals can be converted into torque and rotating speed to drive a control object. The rotation speed of the rotor of the servo motor is controlled by an input signal and can quickly respond, the servo motor is used as an actuating element in an automatic control system, has the characteristics of small electromechanical time constant, high linearity and the like, and can convert a received electric signal into angular displacement or angular speed on a motor shaft for output. The servo motor is divided into two categories of direct current servo motors and alternating current servo motors, and is mainly characterized in that when the signal voltage is zero, the signal voltage has no autorotation phenomenon, and the rotating speed is reduced at a constant speed along with the increase of the torque.

Illustratively, the height of the control surface 400 is one third of the height of the hydrofoil mast 500.

Illustratively, during normal use of the electric hydrofoil, the hydrofoil mast 500 is mostly exposed to the air, while the control surface 400 needs to be completely submerged in the water in order to be able to perform the course control effect; therefore, the control surface 400 is higher than the hydrofoil mast 500 by one third, so that the normal operation of the heading control of the control surface motor 310 in the normal use process can be ensured.

Exemplarily, the electric hydrofoil further includes a main control board 710, and the main control board 710 is electrically connected to the power mechanism 200 and the control surface control mechanism 300, respectively.

Illustratively, the main control board 710 controls the operation of the power mechanism 200 and the control surface control mechanism 300, so as to control the forward propulsion or turning action of the electric hydrofoil.

Illustratively, the electric hydrofoil further comprises a controller 720, and the controller 720 is wirelessly connected with the main control board 710.

Illustratively, the controller 720 is controlled by the user of the electric hydrofoil, and a control signal can be sent to the main control board 710 through the controller 720, so as to control the forward propulsion or turning action of the electric hydrofoil.

Illustratively, the main control board 710 and the controller 720 are each provided with a bluetooth communication module.

Bluetooth enables some current portable mobile and computer devices to connect to the internet without a cable and have wireless access to the internet.

In some embodiments, the main control board 710 and the controller 720 may also use other wireless communication methods for data transmission, which is not limited herein.

Illustratively, the power mechanism 200 includes a power motor 210 and a propeller 220, wherein the power motor 210 is installed at the second end of the connection support rod 600, and the propeller 220 is installed on the rotating shaft of the power motor 210.

For example, the remote controller of the conventional electric hydrofoil product has only one throttle control channel of the propeller motor for output power adjustment of the user in the use of the product. In the electric hydrofoil provided by the embodiment of the present application, a control surface control system (including the control surface control mechanism 300, the control surface 400, the main control board 710, the controller 720, etc.) of the electric hydrofoil is added, so that a corresponding control channel is also required to be added to the controller 720 for adjusting the position of the control surface 400 of the electric hydrofoil. The left and right limits of the control surface control channel on controller 720 map the left and right limit positions of the control surface, respectively. When the controller 720 dials the adjusting button of the control surface control channel, the corresponding control command is transmitted to the main control board 710 through bluetooth communication, the main control board 710 is responsible for converting the information of the amount of the rudder surface controlled by the controller 720 into the absolute position information of the control surface 400 and transmitting the absolute position information to the control surface motor controller 311 through the CAN bus, and the control surface motor controller 311 drives the control surface motor 310 to stop at the desired stall position of the controller 720 through the position control loop, the speed control loop, the current control loop and the vector control module inside the control surface motor controller 311.
