The steering base 401 is formed by connecting an upper casing base 4011 and a lower casing base 4012 to form a closed shell structure, a sealing groove and a sealing ring 412 are arranged between the upper casing base 4011 and the lower casing base 4012, and the sealing ring 412 is pressed through threads to seal and prevent water. The place where the upper casing base 4011 is connected with the steering shaft 403 is provided with a dynamic sealing structure, which also plays a waterproof role.

The steering device 40 further includes a second controller, the second controller is in communication connection with the first controller and the hall position sensor 411, and the second controller is configured to convert the rotation angle of the planet carrier 407 (magnetic element 410) adopted by the hall position sensor 411 into a steering signal and send the steering signal to the first controller, so that the steering device 40 corresponds to the first position and the second position of the connecting rod 202 when located at the minimum rotation angle position and the maximum rotation angle position, respectively.

In some embodiments, a second wireless communication module is disposed on the second controller, and the wireless communication between the electric steering driving device 30 and the steering device 40 is realized through the communication between the first wireless communication module of the electric steering driving device 30 and the second wireless communication module of the steering device 40.

In other embodiments, the first controller of the electric steering drive 30 is connected to the second controller of the steering device 40 by a cable, and the electric steering drive 30 and the steering device 40 are in wired communication. .

The steering device 40 is provided with a power source (battery).

The steering device 40 further comprises an indicator light, a power switch and a communication interface, wherein the indicator light, the power switch and the communication interface are respectively electrically connected with the second controller, and the indicator light, the power switch and the communication interface are exposed out of the outer surface of the steering base. The indicator light is used for indicating at least one of a left-hand deflection state (whether the orientation of the propeller is deflected to the left or the right), a power-on state (whether the power is supplied) of the steering device 40 and whether the power of the power supply is sufficient.

For example, the second controller controls the status of the indicator light to display the current operating mode or position of the steering wheel 402, for example, to display whether the steering wheel 402 is currently rotating counterclockwise or clockwise, or to display whether the steering direction of the boat is currently rotating counterclockwise or clockwise, or to indicate the status of the power source built in the steering device 40, such as normal or low power. And may also be used to alert the second controller or communication failure.

The steering device 40 further includes a port-starboard switch for selectively mounting the electric steering drive 30 in either a port position or a starboard position.

In one embodiment, the steering device 40 further includes a display screen for displaying at least one of a left-turn state of the marine propeller (whether the propeller is oriented to the left or the right), a left-turn angle of the marine propeller, a power-on state of the steering device (whether the steering device is powered on), and power information of the power supply (remaining power, whether the power is sufficient). The display screen may replace the indicator light described above.

The steering device 40 further includes a zero-position input key for correcting the zero position of the steering device 40. During the setup of the electric steering system, turning the steering device 40 causes the electric steering drive device 30 to adjust the orientation of the propeller to a position right behind, and at this position, pressing the zero position input key, causes the second controller of the steering device 40 to store the position information of the steering device 40 at this time, and records this position as the zero position of the steering device 40.

With the steering device 40 in the zero position, an indicator light on the steering device 40 will indicate that the steering device 40 is in the zero position at this time. When the steering device 40 is not located at the zero position, the indicator light of the steering device 40 will display whether the steering device 40 is located at the left or right position, so that the user can know whether the current orientation of the propeller is left or right.

The power switch controls the steering device 40 to be powered on and off, and only the power-on state can work. The communication interface may be in wired communication with the electric steering drive 30.

The steering device of the present embodiment operates in the following manner:

the user rotates the steering wheel 402 to drive the steering shaft 403 and the planetary reducer to rotate together, the position sensor 410 sends the detected angle signal (analog quantity) of the planetary reducer to the second controller, the second controller performs analog-to-digital conversion on the signal, and converts the signal into a digital signal (steering signal), and then sends the steering signal to the first controller of the electric steering driving device 30 through a wireless communication module or a wired transmission mode, and the electric steering driving device 30 drives the motor 301 to rotate according to the signal, so as to adjust the propulsion direction of the marine propeller 20.

The electric steering driving device 30 is powered by a power supply of the marine propeller 20 or an external power supply, and the steering device 40 may be powered by a built-in power supply or may be powered by a cable from the electric steering driving device 30.

When the marine propeller 20 is an electric marine propeller, the power supply 60 of the marine propeller 20 is generally used for power supply.

In other alternatives, the steering device 40 of the above-described structure may be replaced with a key handle similar to a game handle, i.e., clockwise/counterclockwise steering and increase and decrease of the steering angle may be performed by the keys on the handle. The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
