Description
Technical Field
[0001] The utility model relates to the technical field of marine equipment, and particularly relates to an outboard motor. Background Art
[0002] An outboard motor is a commonly used marine propeller, which is convenient to disassemble and install, and is widely used in small fishing boats or hovercrafts. Generally, the outboard motor adjusts the orientation of the propeller located at the bottom of the main rod by rotating the main rod to control the course. At present, some electric outboard motors adopt electric control steering to liberate the hands of the operator and can realize complex controls such as electronic anchoring.
[0003] The propulsion motor of the electric outboard motor needs to be connected to an external power supply or a controller through an external cable. When realizing electronic anchoring through electric control steering, the cable may be wound around the main rod with the multiple rotations of the main rod, resulting in friction between the cable and the main rod during steering, uneven stress on the cable, easy damage to the cable, and reduction of the cable life. Using a conductive slip ring or a rotary joint can avoid the cable from being wound around the main rod, but the conductive ability of the conductive slip ring or the rotary joint is poor and cannot meet the power supply requirements of the propulsion motor. Using a duct or hose with high flexibility as the outer skin of the external cable and cooperating with a specific wiring path can also reduce the probability of winding, but the salt spray resistance and corrosion resistance of such ducts or hoses are poor and cannot adapt to the application scenarios on the water surface or the sea surface. Setting one end of the cable as a quick connector for quick disassembly or replacement can facilitate quick unwinding when winding occurs, but it still requires manual intervention and the user experience is not good. Therefore, it is necessary to design an outboard motor that can automatically untangle the cable winding. Summary of the Utility Model
[0004] In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide an outboard motor, which can respectively obtain the angle of the main rod and the angle of the hull through a first course sensor unit and a second course sensor unit, so that the control system can automatically judge whether there is a winding phenomenon and control the main rod to rotate in the reverse direction to automatically untangle, improving the life of the outboard motor and the user experience at the same time.
[0005] To solve the above problems, the technical solution adopted by the present utility model is as follows: An outboard motor, comprising: a base for connecting to a hull; a steering system disposed on the base; a main rod rotatably connected to the steering system and capable of rotating under the drive of the steering system; a propulsion system disposed on the main rod for providing a propulsion force to drive the hull to move; a first heading sensor unit disposed on the main rod for detecting the angular position of the main rod; a second heading sensor unit disposed on the base or the hull for detecting the angular position of the hull; and a control system disposed on the hull and electrically connected to the steering system, the propulsion system, the first heading sensor unit, and the second heading sensor unit for controlling the operation of the steering system and the propulsion system according to the angular position of the main rod fed back by the first heading sensor unit and the angular position of the hull fed back by the second heading sensor unit.

By comparing the changes in the angular positions of the main rod and the hull, it is possible to automatically determine whether a winding phenomenon occurs, and when a winding occurs, the main rod is automatically driven to rotate in the reverse direction to automatically unwind. This outboard motor can automatically intervene to unwind when a winding occurs, improving the control of the propulsion system and the service life of the power supply cable, and enhancing the user experience.

[0018] The following details the embodiments of the present utility model, referring to Figure 1 and Figure 2 , the embodiments of the present utility model provide an outboard motor, including a base 100, a steering system 110, a main rod 200, a propulsion system, a first heading sensor unit, a second heading sensor unit, and a control system. The base 100 is used for connecting the outboard motor to the hull. The steering system 110 is arranged on the base 100. The main rod 200 is connected to the steering system 110 and can rotate under the drive of the steering system 110. The first heading sensor unit and the propulsion system are both arranged on the main rod 200. The first heading sensor unit is used to detect the angular position of the main rod 200. The propulsion system is used to provide the propulsion force for driving the hull to move. The second heading sensor unit is arranged on the base 100 or the hull and is used to detect the angular position of the hull. The control system is electrically connected to the steering system 110, the propulsion system, the first heading sensor unit, and the second heading sensor unit, and is used to control the steering system 110 and the propulsion system to work according to the angular positions of the main rod 200 and the hull, and control the heading and speed of the hull.
[0019] For the outboard engine according to the embodiment of the present utility model, the control system can respectively obtain the angular position of the main rod 200 and the angular position of the hull through the first heading sensor unit and the second heading sensor unit, so as to obtain the angular difference between the main rod 200 and the hull, and judge whether the cable between the propulsion system and the control system is wound according to the angular difference. After electronic anchoring, when it is detected that the angular difference between the main rod 200 and the hull is greater than 370 degrees, it is judged that the cable is wound, and the steering system 110 can be controlled to drive the main rod 200 to rotate reversely to release the winding of the cable, so as to improve the service life of the cable. At the same time, since the control system can obtain the relative angular positions of the main rod 200 and the hull through the first heading sensor unit and the second heading sensor unit, the hull can be driven in unconventional moving modes such as translational driving more stably and reliably by a single thruster, so that the hull can pass through narrow and crowded waters more accurately, and can stay at the target position more accurately when electronically anchoring.
[0020] In some embodiments, the outboard engine further includes a power supply unit, which is connected to the power supply system of the hull and is used to supply power to the steering system 110, the propulsion system, the first heading sensor unit, the second heading sensor unit and the control system.
[0021] It can be understood that both the first heading sensor unit and the second heading sensor unit can use sensors such as gyroscopes, magnetometers or multi-axis accelerometers to detect the angular position of the target. In this embodiment, both the first heading sensor unit and the second heading sensor unit include a 3-axis accelerometer, a gyroscope and a 3-axis magnetometer, and the angular positions of the main rod 200 and the hull are accurately detected through the fusion of the data of the three sensors.
[0022] Refer to Figure 2, in this embodiment, the thruster system includes a motor controller and a thruster motor 220. To prevent the motor controller from being affected by water vapor and salt spray, the motor controller is disposed within a control handle 210 at the upper end of the main rod 200, and the thruster motor 220 is disposed at the lower end of the main rod 200. A propeller 221 is provided on the output shaft of the thruster motor 220. The control system includes a control unit and a control panel. A control box 120 is provided on the base 100. The control unit is disposed within the control box 120, and the control panel is disposed at the bow of the hull and can communicate with the control unit in a wired or wireless manner. The control unit is used to control the operation of the thruster system and the steering system 110, and the control panel is used for an operator to input control instructions. The control unit can be a programmable controller such as an ARM, an FPGA, or a PLC. In this embodiment, the first heading sensor unit is also disposed within the control handle 210, and the second heading sensor unit is disposed within the control box 120. The motor controller is electrically connected to the thruster motor 220 through an internal cable disposed within the main rod 200. The motor controller and the first heading sensor unit are electrically connected to the control unit in the control box 120 through an external spring cable 211 and obtain power supply from the power supply unit through the spring cable 211. The spring cable 211 can automatically curl into a spring shape when not under external force, preventing the cable from drooping under the action of gravity and preventing the cable from dropping into the water or into other mechanisms and affecting the operation of other mechanisms.
[0023] It can be understood that the steering system 110 includes a steering box and a steering motor and a transmission mechanism disposed within the steering box. The transmission mechanism can be a transmission gear set or a synchronous belt mechanism, etc. The output shaft of the steering motor is in transmission connection with the main rod 200 through the transmission mechanism, and the steering motor is electrically connected to the control unit.
