Description

Technical Field

[0001] This utility model relates to the field of ship outboard motors, specifically a new type of ship outboard motor. Background Technology

[0002] In water transportation, operations, and leisure activities, the performance requirements of propulsion systems for boats and other watercraft are becoming increasingly diverse. Traditional propulsion devices with a single power source (such as a pure engine or a pure electric motor) are unable to meet the requirements for power output, energy efficiency, and functional expansion in different scenarios.

[0003] While pure engine-driven propulsion systems can provide continuous and strong power, they suffer from high fuel consumption and exhaust pollution during low-speed cruising and operations in environmentally sensitive waters (such as ecological protection areas). Furthermore, engine idling can generate noise, affecting the driving experience and the surrounding environment. Pure electric motor-driven systems are limited by battery range and cannot meet the needs of long-distance, high-power navigation. They also suffer from insufficient power output during emergency acceleration and heavy-load conditions, thus limiting the application range of boats.

[0004] Currently, to overcome the aforementioned limitations, integrated hybrid propulsion systems have become a research and development direction. By integrating the engine and motor, it is expected to intelligently switch or work in coordination under different operating conditions: when high-speed navigation and long-range requirements are needed, the engine serves as the main power source, outputting strong power; in low-speed cruising and quiet operation scenarios, the electric motor drives energy saving, environmental protection, and low noise; at the same time, the hybrid mode can optimize energy efficiency and recover braking energy (if adapted to an energy recovery structure), improving the overall range and economy of the system.

[0005] However, existing hybrid propulsion devices face challenges in power coupling and modular integration. The power transmission path design between the engine and the motor is complex, and the layout of transmission components such as gears and gearboxes needs to balance compactness and smooth power connection. In addition, space optimization under the integrated structure (compact installation of each component) also affects the reliability and practicality of the device. To address these issues, we propose a novel outboard motor. Utility Model Content

[0006] The purpose of this invention is to provide a new type of outboard motor that is adaptable to all working conditions and highly reliable, and solves the problems of power coupling and modular integration in existing hybrid propulsion devices.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a novel outboard motor, comprising:

[0008] The housing has an instrument fixedly mounted on its upper left side. An engine is fixedly mounted on the upper part of the housing's inner cavity. The output end of the engine is fixedly connected to an engine input gear via a rotating shaft. A gearbox is located at the lower end of the housing. An engine output gear is located on the left end of the gearbox's inner cavity. Output gears are located at both ends of a coaxial gear set within the gearbox. A propeller is located on the upper right side of the gearbox. A motor is fixedly mounted on the middle of the right side wall of the housing's inner cavity. The output end of the motor is fixedly connected to a motor input gear via a rotating shaft. A controller is fixedly mounted on the inner cavity of the housing, above the motor.

[0009] Preferably, the engine output gear and the motor input gear are adapted to be driven by the gearbox and the output gear.

[0010] Preferably, a cooling pipe is provided at the lower end of the inner cavity of the housing, and the cooling pipe is arranged in close contact with the outer surface of the engine block and the motor winding, and a branch pipe is provided next to the gear meshing area of ​​the gearbox. The cooling pipe is made of stainless steel and heat dissipation fins are provided at the contact point with the heat-generating components.

[0011] Preferably, the output of the controller is connected to the engine and motor signals, and the controller has a built-in power control algorithm.

[0012] Preferably, the instrument is connected to the engine, motor, and controller signals.

[0013] Preferably, the left end of the propeller is connected to the output gear via a coupling.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model has three modes: pure electric, pure engine, and hybrid power. It can be precisely switched by the controller according to different working conditions. With the help of a carefully designed gear transmission structure, the power of the engine and the motor is smoothly coupled in the gearbox, which reduces the fluctuation and impact in the power transmission process, making the boat run more smoothly, providing passengers with a more comfortable riding experience, and also helping to improve the service life of the equipment on board.

[0016] 2. The engine, motor, transmission components, cooling pipes, and controller of this utility model are highly integrated, which effectively reduces the overall size and weight of the device. This not only facilitates installation on boats but also improves the space utilization of boats, making it possible to carry more equipment or passengers.

[0017] 3. This utility model device adopts a modular design concept, with each component being relatively independent yet able to work collaboratively. This makes it more convenient to maintain, upgrade, or replace parts of the equipment. Maintenance personnel can quickly locate and handle problems, reduce downtime, lower maintenance costs, and improve equipment availability. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] The components of this application, including housing 1, instrument 2, engine 3, controller 4, motor 5, cooling pipe 6, gearbox 7, propeller 8, motor input gear 9, output gear 10, engine output gear 11, and engine input gear 12, are all general standard parts or parts known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0022] Example 1

[0023] Please see Figure 1 As shown, this utility model provides a technical solution: a novel outboard motor, comprising:

[0024] The housing 1 has an instrument 2 fixedly mounted on its upper left side. An engine 3 is fixedly mounted on the upper part of the inner cavity of the housing 1. The output end of the engine 3 is fixedly connected to an engine input gear 12 via a rotating shaft. A gearbox 7 is located at the lower end of the housing 1. An engine output gear 11 is located on the left end of the inner cavity of the gearbox 7. Output gears 10 are located at both ends of the coaxial gear set inside the gearbox 7. A propeller 8 is located on the upper right side of the gearbox 7. A motor 5 is fixedly mounted on the middle of the right side wall of the inner cavity of the housing 1. The output end of the motor 5 is fixedly connected to a motor input gear 9 via a rotating shaft. A controller 4 is fixedly mounted on the inner cavity of the housing 1, above the motor 5.

[0025] The engine output gear 11 and the motor input gear 9 are adapted to the output gear 10 through the gearbox 7. The output end of the controller 4 is connected to the engine 3 and the motor 5, and the controller 4 has a built-in power control algorithm. The instrument 2 is connected to the engine 3, the motor 5 and the controller 4. The left end of the propeller 8 is connected to the output gear 10 through a coupling.

[0026] This technical solution: Engine 3 provides fuel power, and motor 5 provides electric drive. Engine output gear 11 and motor input gear 9 are coupled to output gear 10 via gearbox 7, allowing engine 3 and motor 5 to drive output gear 10 independently or collaboratively, enabling multi-mode switching between pure fuel, pure electric, and hybrid power. Controller 4 is connected to engine 3 and motor 5 to regulate power output and the cooling logic of cooling pipe 6. Based on operating parameters (speed, load, temperature, etc.) fed back by instrument 2, it automatically switches the operating modes of engine 3 and motor 5 and synchronously adjusts the medium flow rate of cooling pipe 6 (the built-in power control algorithm is existing technology). Propeller 8 is connected to output gear 10 to receive coupled power and convert it into propulsion. Instrument 2 is connected to engine 3, motor 5, and controller 4 to display equipment operating parameters.

[0027] The power from engine 3 is transmitted to output gear 10 via engine input gear 12 and engine output gear 11, while the power from motor 5 is transmitted to output gear 10 via motor input gear 9. Gearbox 7, as the core coupling component, allows the two power sources to be naturally connected through gear sets. Compared with complex shaft transmission, this reduces the number of components and space occupation, ensuring compactness. At the same time, the meshing characteristics of gear transmission can be matched by module and number of teeth to allow the power output of engine 3 and motor 5 to be seamlessly connected. At low speeds, motor 5 is directly driven (small load, quiet), while at high speeds, engine 3 is dominant (large load, long range). In hybrid mode, the torque of both is superimposed, eliminating the need for a complex clutch mechanism and reducing the risk of power interruption. Furthermore, core components such as engine 3, motor 5, transmission, cooling, and control are integrated into the same housing 1, enabling rapid assembly through standardized interfaces (such as gear connections and quick-connect pipes). The shape of housing 1 is adapted to the space of the ship's engine room, reducing redundant volume. This facilitates installation and maintenance (modular replacement) and reduces vibration coupling through a compact layout, improving operational stability.

[0028] It should be noted that the housing 1, instrument 2, engine 3, controller 4, motor 5, cooling pipe 6, gearbox 7, propeller 8, motor input gear 9, output gear 10, engine output gear 11, and engine input gear 12 used in this outdoor unit can all be purchased directly from the market. At the same time, the connection methods and electrical connections of each component adopt mature and conventional methods in existing technology, so they will not be described in detail here.

[0029] Example 2

[0030] Based on Embodiment 1, this utility model is as follows: Figure 1 As shown, a cooling pipe 6 is provided at the lower end of the inner cavity of the housing 1. The cooling pipe 6 is arranged in close contact with the outer surface of the engine cylinder and the motor winding, and a branch pipe is provided next to the gear meshing area of ​​the gearbox 7. The cooling pipe 6 is made of stainless steel and heat dissipation fins are provided at the contact point with the heat-generating components.

[0031] This technical solution involves a cooling pipe 6 that is arranged in a line along the engine block (high-heat zone), motor windings (electromagnetic heat), and gear meshing area of ​​the gearbox 7 (frictional heat). This allows for targeted removal of heat from different components, and the branch pipe design allows for flexible flow adjustment (e.g., increasing cylinder block cooling when the engine 3 is under high load, and focusing on motor 5 cooling in pure electric mode), ensuring that each component operates within a reasonable temperature range.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
