Description

Technical Field

[0001] This utility model belongs to the field of propulsion technology, specifically, it relates to an outboard motor propulsion system integrating multiple motors. Background Technology

[0002] Traditional fuel-fired outboard motor propulsion systems integrate technologies from multiple fields, continuously optimizing and upgrading power, transmission, and propulsion to adapt to diverse maritime navigation needs. The mainstream engines are gasoline and diesel. Two-stroke gasoline engines, with their simple structure, strong power, and low cost, are suitable for scenarios with high economic and power requirements; however, they consume a lot of fuel and produce significant emissions. Four-stroke gasoline engines, on the other hand, have advantages in environmental performance and noise control, high fuel efficiency, stable and long-lasting operation, and better meet modern environmental standards. Diesel engines have high torque, making them suitable for heavy-duty vessels, but they suffer from large size and weight, difficulty starting, significant noise and vibration, and some pollution to the aquatic environment. Traditional fuel-fired outboard motor propulsion systems operate on a single-engine, single-propulsion basis, requiring multiple outboard motors for high thrust. The disadvantages of this approach are: 1. High pollution and noise levels in the power system, and reliance on fossil fuels. 2. Low transmission and propulsion efficiency, cumbersome maintenance, and insufficient adaptability. 3. Large equipment weight; the increased weight and energy consumption when using multiple outboard motors reduce range. Utility Model Content

[0045] In summary, the beneficial effects of the multi-motor outboard motor propulsion system of this application are as follows: 1. It directly converts electrical energy into mechanical energy through motors, with an energy conversion efficiency generally above 80%, which is much higher than the 30%-40% energy conversion efficiency of traditional fuel-powered outboard motors. This allows for more efficient use of energy and provides stronger power output.

[0046] 2. Lightweight design: The integrated mid-mounted adapter structure reduces redundant parts, lowers the overall weight, and improves the ship's carrying capacity or range.

[0047] 3. No water pollution: Driven by an electric motor, using a power battery pack as the driving energy source, it causes "0" pollution to seawater.

[0048] 4. Multiple motors can be managed through a single control panel interface, and the status of each motor can be monitored in real time, reducing the complexity of operation for crew members.

[0049] The reason why the above technical solution can overcome the shortcomings mentioned in the background art is that:

[0050] 1. Integrated into a single central adapter bracket, reducing the number of parts on the upper part of the mount bracket, lowering the overall weight of the propeller, and increasing range; multiple motors can dynamically allocate power according to real-time load, reducing energy waste and improving overall range.

[0051] 2. The use of electric motor drive and power battery pack ensures that the propulsion system is free from noise pollution and leakage pollution.

[0052] 3. Compared to fuel-powered trailer motors, electric trailer motors have simpler electrical systems to maintain. Abnormal components can be viewed in real time through the control panel's operation and management interface, allowing for precise and effective equipment maintenance.

[0053] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0054] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0055] The above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall be covered by the present utility model.
