[0019] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] See Figure 1-11 As shown in the figure, this application discloses a cruise ship, including a hull 1 and a propeller 2; characterized in that: the hull 1 is a one-piece structure, a groove 11 is provided on the outer bottom of the hull 1, the groove 11 is located in the middle of the hull 1 in the left-right direction and the groove 11 runs through the hull 1 from front to back, the propeller 2 is located at the rear end of the groove 11 and is connected to the rear end of the hull 1; when the hull 1 floats on the water surface, there is a gap between the top of the groove 11 and the water surface, and at least a part of the propeller 2 is submerged in the water; the hull is integrally injection molded from plastic material.

[0021] The cruise ship also includes an electric steering mechanism 3 and a steering arm 4. The electric steering mechanism 3 is fixed in the middle of the rear end of the hull 1, and the steering arm 4 is vertically arranged. The upper end of the steering arm 4 is connected to the output end of the electric steering mechanism 3, and the propeller 2 is fixed to the lower end of the steering arm 4. The electric steering mechanism 3 is used to adjust the angle of the propeller 2 relative to the hull 1 to change the direction of travel of the hull 1. With the electric steering mechanism, when the hull needs to turn, the electric steering mechanism can adjust the angle of the propeller relative to the hull, thereby changing the direction of travel of the hull. Compared with the cruise ship disclosed in Chinese Patent Publication No. CN220577492U, which uses two propellers to control steering, it has the advantages of simple control, simple structure and low cost.

[0022] The electric steering mechanism 3 includes a housing assembly 31, a rotating shaft 32, a motor 33, and an angle sensor 34. The housing assembly 31 is fixed to the middle of the rear end of the hull 1. The rotating shaft 32 is vertically arranged and rotatably connected to the housing assembly 31. The motor 33 is fixed inside the housing assembly 31, and the rotating shaft 32 is drivenly connected to the motor 33. The angle sensor 34 is fixed inside the housing assembly 31. The upper end of the rotating shaft 32 is drivenly connected to the detection end of the angle sensor 34, and the lower end of the rotating shaft 32 extends out of the housing assembly 31 and forms the output end of the housing assembly 31. The lower end of the rotating shaft 32 is fixed to the upper end of the steering arm 4. The propeller 2, the motor 33, and the angle sensor 34 are all electrically connected to the controller 5 in the cruise ship. By adopting this electric steering mechanism, the angle sensor can obtain the rotation angle status of the motor-driven rotating shaft, the steering arm, and the propeller relative to the hull in real time, and can provide real-time information when the passenger operates the cruise ship. When turning, the controller can control the motor to drive the shaft, steering arm, and thruster to rotate to the target angle based on the angle data obtained by the angle sensor and the steering operation of the tourist, thereby changing the direction of travel of the cruise ship. Furthermore, the shaft 32 is rotatably connected to the housing assembly 31 through two bearing sets distributed vertically. With this structure, the shaft can be reliably rotatably connected to the housing assembly. In addition, the shaft is axially limited to the housing assembly through the two bearing sets. Furthermore, both the shaft 32 and the steering arm 4 are provided with vertical through holes for the connection wires between the thruster 2 and the controller 5 to pass through vertically. With this structure, the connection wires between the thruster and the controller can be passed through the through holes of the shaft and the steering arm, thereby hiding the connection wires to avoid damage and prevent the connection wires from getting tangled.

[0023] A driven gear 35 is fixedly sleeved on the outside of the rotating shaft 32 located inside the housing assembly 31, and a driving gear 331 is coaxially fixed on the output shaft of the motor 33. The driven gear 35 meshes with the driving gear 331. With this structure, the rotating shaft can be reliably connected to the output shaft of the motor through the cooperation of the driving gear and the driven gear, so that the motor can reliably drive the rotating shaft to rotate.

[0024] The driven gear 35 is provided with an arc-shaped hole 351, the axis of which coincides with the axis of the driven gear 35. A limit post 36 is fixed on the inner bottom of the housing assembly 31. The upper end of the limit post 36 is inserted into the arc-shaped hole 351 and slides in cooperation with it. With this structure, when the angle sensor fails or is damaged, the rotation angle of the shaft, steering arm and thruster can be mechanically limited by the cooperation of the limit post and the arc-shaped hole, so as to avoid the situation where the boat loses control or capsizes due to excessive rotation of the thruster.

[0025] An opening slot 12 is provided in the middle of the rear end of the hull 1, and a support step 13 is provided at the upper end of the opening slot 12. The shell assembly 31 is inserted into the opening slot 12 from rear to front, and the lower end of the shell assembly 31 abuts against the support step 13. With this structure, the hull can reliably support the electric steering mechanism, steering arm, and propeller, so that the electric steering mechanism, steering arm, and propeller are reliably fixed to the hull. A flange 311 is provided on the outer wall of the shell assembly 31, and a number of flanges along the circumferential direction of the support step 13 are fixed on the side wall of the support step 13. The support seats 61 are spaced apart, and each support seat 61 is rotatably connected to a screw 62. A hand-tightening nut 63 is threaded onto each screw 62. A groove 312 corresponding to each screw 62 is provided on the outer wall of a flange 311. Each screw 62 is engaged in the corresponding groove 312, and the flange 311 is pressed against the support seat 61 by the hand-tightening nut 63. With this structure, when each hand-tightening nut is loosened and each screw rotates relative to the support seat and moves out of the groove, the electric steering mechanism can be horizontally moved out of the slot, i.e., it can... It allows for convenient disassembly and assembly of the electric steering mechanism, steering arm, and propeller from the hull, facilitating their maintenance. Furthermore, during assembly, the housing assembly is simply slid from back to front into the slot and rests against the support step. Each screw is then rotated to engage in its corresponding slot, and finally, the hand-tightened nut is tightened to press the flange against the support. This method facilitates the easy integration of the electric steering mechanism, steering arm, and propeller with the hull. The assembly is as follows: In addition, a handle is fixed to the upper end of the housing assembly 31; with the handle, when the electric steering mechanism, steering arm and propeller need to be separated from the hull, after the electric steering mechanism is released from the hull, the handle can be used to move the electric steering mechanism out of the opening slot, thereby facilitating the disassembly of the electric steering mechanism, steering arm and propeller from the hull; similarly, when the electric steering mechanism, steering arm and propeller need to be assembled with the hull, the handle can be used to move the electric steering mechanism into the opening slot, and the housing assembly and hull can be fixed.

[0026] The cruise ship also includes a fixing frame 7; the rear end of the fixing frame 7 is fixed to the upper edge of the propeller 2, and the front end of the fixing frame 7 is provided with a slot 71, in which the middle part of the steering arm 4 is inserted. The fixing frames 7 on both sides of the slot 71 are fastened to the steering arm 4. By adopting this structure, the fixing strength between the propeller and the steering arm can be effectively improved under the action of the fixing frame, that is, when the propeller propels the hull forward, it can effectively prevent the propeller from detaching from the steering arm.

[0027] A central control panel 14 is located in the middle of the inner side of the hull 1. Several functional compartments 141 with openings at the top are located inside the central control panel 14. The left, right and front sides of the central control panel 14 form a cabin 15. Drainage holes 142 are provided at the bottom of the cabin 15 and at the bottom of each functional compartment 141. The lower end of each drainage hole 142 is connected to the top of the groove 11. A one-way drain 8 is circumferentially sealed at the upper end of each drainage hole 142. With the above structure, when the hull floats on the water, there is a gap between the top surface of the groove and the water surface. Since drainage holes are provided at the bottom of each functional compartment and the bottom of the cabin, water or rainwater entering the functional compartment and cabin can be discharged to the outside of the hull in a timely manner through the drainage holes. Under the action of the one-way drain, water splashed up when the hull is moving can be prevented from flowing back into the cabin and functional compartment through the drainage holes.

[0028] The cruise ship also includes a battery cover 16, a display panel 17, a control panel 18, and a storage cover 19. The battery cover 16 is detachably mounted on the upper part of the first functional compartment 141, which is used to house the battery. The display panel 17 is fixed on the upper part of the second functional compartment 141, the controller 5 is fixed inside the third functional compartment 141, the control panel 18 is fixed on the upper part of the third functional compartment 141, and the storage cover 19 is mounted on the upper part of the fourth functional compartment 141, which is used to store items. The battery, display panel 17, and control panel 18 are all electrically connected to the controller 5. With this structure, after the battery is installed in the first functional compartment and the battery cover is mounted on the first functional compartment, the storage cover 19 can be detachably mounted on the second functional compartment 141. After the top of the functional compartment is closed, the battery cover reliably prevents water or rainwater from entering the first functional compartment through the opening at the top. Visitors can place their belongings in the fourth functional compartment, and with the cover closed, it reliably prevents water or rainwater from entering the fourth functional compartment through the opening at the top, thus preventing their belongings from getting wet. Wiring holes 143 are provided between the second functional compartment 141 and the first and third functional compartments 141, through which the connection wires between the battery and the controller 5, and between the display panel 17 and the controller 5, are passed. This structure allows for efficient connection of the battery and display panel. The wiring between the board and the controller is convenient, and the connection wires between the battery and the controller, as well as the connection wires between the display panel and the controller, can be hidden in the functional compartment to improve the aesthetics of the cruise ship. An annular step 144 is provided at the outer edge of the upper end of the first functional compartment 141. The lower end of the outer edge of the battery cover 16 abuts against the annular step 144 and is horizontally limited by the annular step 144. Both the left and right sides of the battery cover 16 are locked to the center console 14 by at least one first latch assembly 161. With this structure, after the lower end of the outer edge of the battery cover abuts against the annular step, the horizontal limitation of the battery cover and the center console can be achieved, thus facilitating the assembly of the battery cover and the center console and improving the reliability of the assembled battery cover and center console. In addition to reliability, the battery cover is locked to the center console via a first latch assembly, which has the advantage of easy assembly and disassembly of the battery cover and the center console; the rear side of the storage cover 19 is rotatably connected to the center console 14 located behind the fourth functional compartment 141 via several hinges 191 spaced from left to right, and the front side of the storage cover 19 is rotatably connected to the center console 14 located in front of the fourth functional compartment 141 via at least one second latch assembly 192; with this structure, when the second latch assembly is unlocked, the storage cover can be rotated open relative to the center console, and after the storage cover is placed on the upper end of the fourth functional compartment, the storage cover can be locked to the center console via the second latch assembly, which has the advantage of easy opening and closing of the storage cover; the cruise ship also includes two seats 10;Two seats 10 are fixed in the cabins 15 located on the left and right sides of the center console 14. This structure allows passengers to easily operate the control panel after sitting in the seats, thus providing convenience for boat operation. The boat also includes a tent 20; the two ends of the tent 20 are fixed to the upper ends of the left and right sides of the hull 1. The tent provides shade while passengers are operating the boat, improving their comfort.

[0029] The bottom of the third functional compartment 141 is vertically provided with a channel 145. A heat-conducting plate 146 is circumferentially sealed and fixed at the upper end of the channel 145. The lower end of the channel 145 is connected to the top of the groove 11. The lower end face of the controller 5 contacts the heat-conducting plate 146 for heat conduction. With the above structure, when the hull moves on the water, the movement of the hull will cause the water to ripple. At this time, the water ripples generated by the ripples can contact the lower end face of the heat-conducting plate through the groove and channel. Since the lower end face of the controller contacts the heat-conducting plate for heat conduction, the heat generated by the controller can be reliably transferred to the heat-conducting plate. The heat is conducted to the water, enabling reliable heat dissipation for the controller and preventing overheating damage, thus extending its lifespan. A circumferentially expanding limiting groove 147 is provided at the upper end of channel 145. The heat-conducting plate 146 is supported on the bottom of the limiting groove 147, with its outer edge fitting against the side wall of the limiting groove 147. The heat-conducting plate 146 is fixed to the limiting groove 147 and circumferentially sealed. This structure allows the heat-conducting plate to be confined within the limiting groove, ensuring reliable fixation at the upper end of the channel. This facilitates the fixing of the heat-conducting plate to the upper end of the channel; the outer edge of the heat-conducting plate 146 is glued and fixed to the bottom surface of the limiting groove 147 and circumferentially sealed; with this structure, the heat-conducting plate can be reliably and conveniently fixed in the limiting groove, and the heat-conducting plate and the limiting groove can reliably achieve circumferential sealing; the outer edge of the heat-conducting plate 146 is fastened to the limiting groove 147 by a number of circumferentially spaced screws 148; with this structure, under the action of the number of circumferentially spaced screws, the heat-conducting plate can be further reliably fixed at the upper end of the channel, that is, it has... The heat-conducting plate has the advantage of high fixation strength to the hull at the upper end of the channel; the heat-conducting plate 146 is made of aluminum alloy, and the lower end face of the controller 5 is in close contact with the upper end face of the heat-conducting plate 146; by adopting this structure, the heat-conducting plate made of aluminum alloy has the advantage of high heat conduction efficiency, and since the lower end face of the controller is in close contact with the upper end face of the heat-conducting plate, the heat-conducting plate can reliably conduct the heat generated by the controller to the water so that the water can reliably dissipate heat from the controller; in addition, the heat-conducting plate made of aluminum alloy has the advantage of good corrosion resistance after contacting the water.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
