Description

Technical Field

[0001] This utility model belongs to the technical field of outboard motor installation devices, specifically relating to an outboard motor lifting mechanism. Background Technology

[0002] Currently, common outboard motor lifting mechanisms on the market typically include basic components such as a protective frame, actuators, and mounting brackets. However, the structural layout of such mechanisms in existing technology is often inefficient. Actuators are often installed laterally or at an angle, occupying a large amount of lateral space, resulting in a bulky and significantly heavy overall mechanism. This not only increases the ship's load burden, affecting its navigation performance and fuel economy, but also restricts its flexibility in adapting to outboard motors of different horsepower, making it difficult to expand its application range through simple component adjustments.

[0003] Therefore, based on some of the situations in the prior art described above, this application has made further designs and improvements. Utility Model Content

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution.

[0005] An outboard motor lifting mechanism includes a protective frame, an actuator, and a mounting frame. The actuator is housed within the protective frame, and the mounting frame is slidably connected to the protective frame. The output end of the actuator is connected to the mounting frame to drive the mounting frame in linear motion. The mounting frame has a first mounting surface on one side of its front for connection with the outboard motor, and two symmetrical sliding parts on its back side, forming a receiving space between the two sliding parts that is adapted to the width of the actuator. The protective frame has a groove on one side of its front for engaging the sliding parts, and a second mounting surface on its back side for connection with the hull. The second mounting surface has a channel in the middle with a width greater than the width of the actuator. The protective frame has a mounting space in the middle. The actuator is installed with its width direction facing the longitudinal orientation of the receiving space, with part of its motor body housed within the receiving space and the other part within the mounting space. By using the mounting frame with its first mounting surface and sliding parts, and cooperating with the groove and mounting space of the protective frame, the actuator is installed laterally and partially housed within the receiving and mounting spaces, resulting in a compact overall structure, reduced weight and volume, and easier assembly and maintenance.

[0006] As a preferred embodiment of an outboard motor lifting mechanism, the mounting bracket includes a mounting base, a mounting plate, and two sliding plates. The mounting plate is mounted on the front of the mounting base, with the first mounting surface located on the mounting plate. The two sliding plates are symmetrically mounted on the back of the mounting base, with two sliding parts corresponding to the two sliding plates. The modular design simplifies the manufacturing and assembly process, reduces production costs, and the mounting plate is equipped with mounting holes for accommodating different specifications of outboard motors, allowing for compatibility with various models of outboard motors.

[0007] In a preferred embodiment of an outboard motor lifting mechanism, the mounting base is provided with a mounting portion, the mounting portion is provided with a first mounting pin, and the output end is provided with a first hinge joint, which is hinged to the first mounting pin. The hinge design allows the actuator to adapt to small deviations during operation, improving the durability and adaptability of the mechanism.

[0008] As a preferred embodiment of an outboard motor lifting mechanism, the mounting section includes a front plate and two side plates located on either side of the front plate. The front plate is integrally formed with the mounting base. The two side plates are detachably fixed to the front plate by fasteners, and the two ends of the first mounting pin are respectively mounted on the two side plates. The integral forming of the front plate and the mounting base improves the overall structural integrity and strength, while the fastener connection of the side plates facilitates disassembly and maintenance, reducing maintenance costs.

[0009] As a preferred embodiment of an outboard motor lifting mechanism, the protective frame includes two protective plates, two mounting plates, and a support rod.

The two protective plates are connected by the mounting plates and the support rod. The two mounting plates are located in the bottom area of ​​the protective plates, and the support rod is located in the top area of ​​the protective plates. This design forms a robust frame structure, effectively protecting the actuator from external impacts. A second mounting pin is installed between the two mounting plates, and a second hinge joint is provided at the bottom of the actuator, which is hinged to the second mounting pin. The hinge design allows the actuator to adapt to small deviations during operation, improving the durability and adaptability of the mechanism.

[0010] As a preferred embodiment of an outboard motor lifting mechanism, the actuator is an electro-hydraulic actuator, which can provide greater thrust and excellent load holding performance, thereby enabling stable adaptation to outboard motors with higher horsepower and effectively expanding the application range of the product.

[0027] refer to Figures 1 to 8 An outboard motor lifting mechanism includes a protective frame 100, an actuator 200, and a mounting frame 300. The actuator 200 is housed within the protective frame 100, and the mounting frame 300 is slidably connected to the protective frame 100. The output end of the actuator 200 is connected to the mounting frame 300, thereby driving the mounting frame 300 to perform linear lifting motion.

[0028] The mounting bracket 300 has a first mounting surface 321 on one side of its front for connection with an outboard motor, and two symmetrical sliding parts on its back side, forming a receiving space between the two sliding parts that is adapted to the width of the actuator 200. Specifically, the mounting bracket 300 includes a mounting base 310, a mounting plate 320, and two sliding plates 330. The mounting plate 320 is mounted on the front of the mounting base 310, and the first mounting surface 321 is located on the mounting plate 320. The two sliding plates 330 are symmetrically mounted on the back of the mounting base 310, and the two sliding parts are respectively located on the two sliding plates 330. The modular design simplifies the manufacturing and assembly process, reduces production costs, and the mounting plate has assembly holes for adapting to different specifications of outboard motors, enabling compatibility with different models of outboard motors.

[0029] The mounting base 310 is further provided with a mounting section 340, on which a first mounting pin 350 is mounted. The output end of the actuator 200 is provided with a first hinge joint 210, which forms a hinged connection with the first mounting pin 350, allowing the actuator 200 to adapt to a certain range of installation deviations during operation, thereby improving the system's adaptability and operational reliability. Furthermore, the mounting section 340 includes a front plate 341 and two side plates 342 located on both sides of it. The front plate 341 and the mounting base 310 are integrally formed, ensuring overall load-bearing strength. The two side plates 342 are detachably connected to the front plate 341 by fasteners. The two ends of the first mounting pin 350 are respectively mounted on the two side plates 342, facilitating subsequent maintenance and component replacement.

[0030] The protective frame 100 has a sliding groove 112 on one side of its front end that mates with the sliding part of the mounting frame 300, and a second mounting surface 111 on its back end for connection to the hull. The second mounting surface 111 has a channel in its center that is wider than the actuator 200, facilitating the installation and maintenance of the actuator 200. The protective frame 100 has an internal installation space. Specifically, the protective frame 100 includes two symmetrically arranged protective plates 110, two mounting plates 120 connecting the two protective plates 110, and a support rod 130. The second mounting surface 111 is located on the protective plates 110. The two mounting plates 120 are located at the bottom of the protective plates 110, and the support rod 130 is located at the top, together forming a high-rigidity frame structure that effectively protects the internal actuator 200 from external impacts. A second mounting pin is installed between the two mounting plates 120. The actuator 200 has a second hinge joint 220 at its bottom, which is hinged to the second mounting pin, further ensuring the stability and alignment performance of the actuator 200 during operation. This protective frame system integrates overlapping mechanical components, eliminates unnecessary structural units, and integrates the second mounting surface 111 with the lifting slide. By simplifying redundant parts and reducing the use of bolts and fasteners, it achieves a compact structural design and realizes efficient material utilization while ensuring mechanical performance, thereby effectively reducing manufacturing costs.

[0031] The actuator 200 is installed in a longitudinal orientation facing the receiving space in the width direction. Part of its body is placed in the receiving space of the mounting bracket 300, and the other part is placed in the mounting space of the protective bracket 100. This layout makes full use of the structural space, making the overall mechanism more compact, effectively reducing weight and volume, and facilitating assembly and subsequent maintenance.

[0032] In this embodiment, the actuator 200 is an electro-hydraulic actuator 200, which features high output thrust and good load holding performance, enabling it to reliably lift and maintain a high-horsepower outboard motor (such as a 150HP model), significantly expanding the applicability of this mechanism. This electro-hydraulic actuator 200 integrates a manual relief valve, ensuring the outboard motor descends to a safe position in the event of an external circuit failure. Furthermore, the protective frame 100 and mounting bracket 300 can be equipped with corrosion-resistant zinc blocks to enhance corrosion resistance, achieving an overall protection rating of IP68.
