[0029] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0030] Reference Figure 1The rudder system structure of the first aspect of the present invention includes: a stern 100, which is provided with a rudder arm 130, a rudder motor 110, and a rudder stick 120. The rudder motor 110 is located on the upper side of the stern 100, and the rudder stick 120 passes through the stern 100. The rudder motor 110 drives the rudder stick 120 to rotate. The rudder arm 130 protrudes horizontally to form a rudder knob 131, and a rudder pin 231 is rotatably provided on the rudder knob 131; and a rudder blade 200, which is connected to the rudder stick 120, and the rudder blade 200 is provided with a support portion 240. The rudder pin 231 and mounting recess 201 are provided. The support part 240 protrudes from the rudder blade 200. The mounting recess 201 is located above the support part 240. The rudder button 131 is placed in the mounting recess 201. The rudder pin 231 passes through the rudder button 131 and connects to the support part 240. The rudder pin 231 and the rudder button 131 are rotatably connected. A housing 220 is detachably provided in the mounting recess 201. The housing 220 is located above the rudder button 131. Both the housing 220 and the support part 240 are close to the rudder button 131.

[0031] During assembly, refer to Figure 6 On the ground or in the workshop, the rudder pin 231 is pre-installed onto the rudder blade 200. Then, the rudder blade 200 is transported to the slipway for assembly with the stern 100. During assembly, the rudder blade 200 is driven to insert the rudder knob 131 into the mounting recess 201. Then, the rudder pin 231 is aligned with the rudder knob 131 from bottom to top, allowing the rudder knob 131 and rudder pin 231 to engage. Simultaneously, the upper side of the rudder blade 200 connects upwards to the rudder stock 120. A detachable housing 220 is provided within the mounting recess 201 to enlarge the rudder knob 131. The movable space within the mounting recess 201 reduces the difficulty of operation, thereby improving operational efficiency. After the rudder button 131 is connected to the rudder pin 231, the housing 220 is then welded to the rudder blade 200. The housing 220 is located above the rudder button 131, thus completing the assembly of the rudder system structure. The housing 220 and the support 240 cooperate to position the rudder button 131, while making the structure between the rudder blade 200 and the stern 100 compact and easy to operate, shortening the installation cycle, improving the utilization rate of the slipway, and saving time and costs.

[0032] Furthermore, it is understandable that, referring to Figure 7 When disassembling the rudder blade 200, the rudder blade 200 can be moved downward by removing the housing 220 and unlocking the rudder blade 200 from the rudder stick 120, so that the rudder pin 231 is separated from the rudder button 131. The rudder pin 231 does not need to be removed during the disassembly process, which is convenient, shortens the disassembly time of the rudder blade 200, facilitates maintenance and replacement, and saves time and costs.

[0033] Understandably, referring to Figure 1A rudder stock support 211 is provided on the upper side of the rudder blade 200. The rudder stock support 211 is equipped with a first hydraulic nut 213, which securely connects the rudder stock 120 to the rudder stock support 211. The rudder stock support 211 is installed on the upper side of the rudder blade 200, the rudder stock 120 mates with the rudder stock support 211, and then the rudder stock 120 is locked onto the rudder stock support 211 by the first hydraulic nut 213. Assembly is convenient, and disassembly is also easy. By loosening the first hydraulic nut 213, the rudder stock 120 can be separated from the rudder stock support 211, which is quick and easy. Furthermore, the connection between the rudder stock support 211 and the rudder stock 120 facilitates maintenance.

[0034] Understandably, referring to Figure 3 The rudder blade 200 has a first mounting slot that matches the rudder stock support 211. A first clearance groove is formed on the bottom wall of the first mounting slot, and first baffles 212 are installed at both ends of the first clearance groove. The first mounting slot facilitates the positioning of the rudder stock support 211 onto the rudder blade 200, enabling rapid assembly and improving efficiency. Furthermore, the first clearance groove allows the rudder stock 120 to pass through the rudder stock support 211 and be locked by a first hydraulic screw. The first hydraulic screw is positioned below the clearance groove, facilitating operation and reducing operational difficulty. The first baffles 212 then cover the clearance groove, protecting the first hydraulic nut 213 and maintaining the integrity of the rudder blade 200's appearance.

[0035] Similarly, it is understandable that, with reference to Figure 1 and Figure 3 The rudder blade 200 is equipped with a rudder pin support 232, which is located below the rudder knob 131. The rudder pin support 232 is equipped with a second hydraulic nut 233, which securely connects the rudder pin 231 to the rudder pin support 232. By connecting the rudder pin 231 to the rudder pin support 232 and then locking the rudder pin 231 onto the rudder pin support 232 using the second hydraulic nut 233, the process is simple and quick. Furthermore, by pre-installing the rudder pin 231 onto the rudder pin support 232, this can be done on the ground or in the workshop, reducing the occupation of the slipway, shortening the slipway's service life, and saving costs.

[0036] Understandably, referring to Figure 3The support portion 240 has a second mounting groove that matches the rudder pin support 232. The bottom wall of the second mounting groove has a second clearance groove, and both ends of the clearance groove are provided with second baffles 234. By installing the rudder pin support 232 into the second mounting groove, the rudder pin support 232 can be quickly positioned, improving assembly efficiency. Furthermore, the clearance groove allows the rudder pin 231 to pass through the rudder pin support 232, facilitating operation of the second hydraulic nut 233 when its lower end connects to it. This simplifies operation and improves efficiency. After tightening the second hydraulic nut 233, the second baffles 234 close the clearance groove, protecting the second hydraulic nut 233 while maintaining the integrity of the rudder blade 200's shape, resulting in an aesthetically pleasing appearance.

[0037] Understandably, referring to Figure 1 The rudder knob 131 is located between the housing 220 and the rudder pin support 232.
