Description

Technical Field

[0001] This utility model relates to ship propeller technology, and more particularly to a hydraulic cylinder support structure for outboard motor oscillation. Background Technology

[0002] Currently, boats generate propulsion power through marine propulsion systems. Common types of marine propulsion systems include outboard motors, inboard motors, and podded propulsion systems. During boat operation, steering control is required to adjust the boat's direction. This is typically achieved by adding a steering mechanism to adjust the direction of the propeller, thereby changing the propulsion direction and thus the boat's trajectory.

[0003] Patent document with application number "CN200910138247.9" discloses a method for installing propellers on small boats, which determines the pitch and boom angles of the propeller installation based on the center of gravity of the water resistance on the boat. To improve the agility and responsiveness of small boats, the propeller is fixed to a plate-type rudder at a certain pitch or boom angle, and installed at the bow and stern of the small boat. This allows for the production of fast-responding and maneuverable small boats.

[0004] Patent document CN200910105714.8 discloses a pull-type propeller drive system for planing boats. Its main features include: a pull-type propeller installed at the bottom of the boat, a V-type gearbox, a hull tunnel composed of three curves with different curvatures, and a double rudder at the stern. The pull-type propeller drive planing boat offers advantages such as saving engine room space, eliminating the disturbance of the drive shaft and its support to the water flow, and reducing the frictional resistance between the hull and the water flow. These advantages increase the drive efficiency at the same power output. We designed a 13-meter planing boat, employing both conventional propeller drive and pull-type propeller drive methods. The speed of the planing boat driven by the pull-type propeller was 3.9 knots higher than that of the conventionally propeller-driven boat, verifying the effectiveness of the pull-type propeller drive system for planing boats.

[0005] The aforementioned patent documents, in conjunction with existing technology, reveal the following defects in the existing hydraulic cylinder support structure used for outboard motor oscillation:
