Description

Technical Field

[0001] This utility model relates to the field of amusement boat technology, and more specifically, to a cruise boat with electric steering function. Background Technology

[0002] Cruise ships are recreational vessels used by tourists to drive on the water. Currently, Chinese Patent Publication No. CN220577492U discloses a cruise ship that relies on the cooperation of a battery pack, controller, and two propellers to achieve electric drive of the hull. Compared with the traditional method of using an internal combustion engine to drive the hull, it has the advantages of being clean and environmentally friendly. However, in the above-mentioned cruise ship structure, when the cruise ship needs to turn, it needs to rely on the cooperation of two propellers to turn. This not only has the disadvantage of troublesome steering control of the cruise ship, but also has the disadvantages of complex structure and high cost due to the use of two propellers. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a cruise ship with electric steering function, which has the advantages of simple control, simple structure and low cost compared with the traditional cruise ship that uses two propellers to control steering.

[0004] This utility model provides a cruise ship with electric steering function, including a hull and a propeller; the cruise ship also includes an electric steering mechanism and a steering arm; the electric steering mechanism is fixed in the middle of the rear end of the hull, the steering arm is vertically arranged, the upper end of the steering arm is connected to the output end of the electric steering mechanism, and the propeller is fixed to the lower end of the steering arm; the electric steering mechanism is used to adjust the angle of the propeller relative to the hull to change the direction of travel of the hull.

[0005] This invention, through the setting of an electric steering mechanism, can adjust the angle of the propeller relative to the hull when the hull needs to turn, thereby changing the direction of the hull's travel. Compared with the traditional cruise ship method of using two propellers to control steering, it has the advantages of simple control, simple structure and low cost.

[0006] In one possible implementation, the electric steering mechanism includes a housing assembly, a rotating shaft, a motor, and an angle sensor. The housing assembly is fixed to the middle of the rear end of the hull. The rotating shaft is vertically positioned and rotatably connected to the housing assembly. The motor is fixed inside the housing assembly, and the rotating shaft is driven by the motor. The angle sensor is fixed inside the housing assembly. The upper end of the rotating shaft is driven by the detection end of the angle sensor. The lower end of the rotating shaft extends out of the housing assembly and forms the output end of the housing assembly. The lower end of the rotating shaft is fixed to the upper end of the steering arm. The propeller, motor, and angle sensor are all electrically connected to the controller in the cruise ship. By adopting this electric steering mechanism, the angle sensor can acquire the rotation angle state of the motor-driven rotating shaft, steering arm, and propeller relative to the hull in real time. When the cruise ship is turned by the passenger, the controller can control the motor-driven rotating shaft, steering arm, and propeller to rotate to the target angle based on the angle data acquired by the angle sensor and the passenger's steering operation, thereby changing the direction of travel of the cruise ship.

[0007] In one possible implementation, a driven gear is fixedly sleeved on the outside of the rotating shaft located inside the housing assembly, and a driving gear is coaxially fixed on the output shaft of the motor. The driven gear meshes with the driving gear. 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.

[0008] In one possible implementation, the driven gear is provided with an arc-shaped hole, the axis of which coincides with the axis of the driven gear. A limit post is fixed on the inner bottom of the housing assembly, and the upper end of the limit post is inserted into the arc-shaped hole and slides in fit 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 propeller causes the cruise ship to lose control and capsize due to excessive rotation.

[0009] In one possible implementation, the shaft is rotatably connected to the housing assembly via two bearing assemblies spaced vertically apart; 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 via the two bearing assemblies.

[0010] In one possible implementation, an opening slot is provided in the middle of the rear end of the hull, and a support step is provided at the upper end of the opening slot. The shell assembly is inserted into the opening slot from rear to front, and the lower end of the shell assembly abuts against the support step. 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.

[0011] In one possible implementation, a flange is provided on the outer wall of the housing assembly, and several support seats are fixed on the side wall of the support step, spaced apart along the circumferential direction of the support step. Each support seat is rotatably connected to a screw, and a hand-tightening nut is threaded onto the screw. The outer wall of the flange is provided with a slot corresponding to each screw, and each screw is engaged in the corresponding slot, with the flange pressed against the support seat by the hand-tightening nut. With this structure, when each hand-tightening nut is loosened and each screw has rotated relative to the support seat and moved out of the slot, the electric steering mechanism can be activated from the open slot. The horizontal removal allows for easy disassembly of the electric steering mechanism, steering arm, and propeller from the hull, facilitating maintenance of these components. Furthermore, during assembly, the housing assembly is simply slid from back to front into the opening slot, resting against the support step. Each screw is then rotated to engage with its corresponding slot, and finally, the hand-tightened nut presses the flange against the support base. This process facilitates the easy assembly of the electric steering mechanism, steering arm, and propeller from the hull.

[0012] In one possible implementation, both the pivot and the steering arm are provided with vertical through holes for the connection wires between the thruster and the controller to pass through vertically. With this structure, the connection wires between the thruster and the controller can be passed through the through holes in the pivot and the steering arm, thereby hiding the connection wires to avoid damage and to prevent the connection wires from getting tangled.

[0013] In one possible implementation, a handle is fixed to the upper end of the housing assembly. With the handle, when the electric steering mechanism, steering arm, and propeller need to be separated from the hull, the handle can be used to move the electric steering mechanism out of the opening slot after it has been released from its fixed position. This facilitates 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 then be secured.

[0014] In one possible implementation, the cruise ship also includes a fixing frame; the rear end of the fixing frame is fixed to the upper edge of the propeller, the front end of the fixing frame is provided with a slot, the middle part of the steering arm is inserted into the slot, and the fixing frames on both sides of the slot are fastened to the steering arm; 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.

[0025] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0026] See Figure 1-7 As shown in the figure, this application discloses a cruise ship with electric steering function, including a hull 1 and a propeller 2; 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, the steering arm 4 is arranged vertically, 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.

[0027] 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, and the upper end of the rotating shaft 32 is drivenly connected to the detection end of the angle sensor 34. 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 32 is fixed to the upper end of the steering arm 4. The thruster 2, motor 33 and angle sensor 34 are all electrically connected to the controller in the cruise ship. By adopting this electric steering mechanism, the angle sensor can obtain the rotation angle status of the motor drive shaft, steering arm and thruster relative to the hull in real time. When the tourists operate the cruise ship to turn, the controller can control the motor drive shaft, steering arm and thruster to rotate to the target angle according to the angle data obtained by the angle sensor and the tourist's steering operation, so as to change the direction of travel of the cruise ship.

[0028] 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.

[0029] 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.

[0030] The rotating shaft 32 is rotatably connected to the housing assembly 31 via two bearing assemblies spaced vertically apart. With this structure, the rotating shaft can be reliably rotatably connected to the housing assembly. In addition, the rotating shaft is axially limited to the housing assembly via the two bearing assemblies.

[0031] An opening slot 11 is provided in the middle of the rear end of the hull 1, and a support step 12 is provided at the upper end of the opening slot 11. The shell assembly 31 is inserted into the opening slot 11 from rear to front, and the lower end of the shell assembly 31 abuts against the support step 12. 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.

[0032] The outer wall of the housing assembly 31 is provided with a flange 311. Several support seats 51, spaced apart along the circumferential direction of the support step 12, are fixed to the side wall of the support step 12. Each support seat 51 is rotatably connected to a screw 52, ​​and a hand-tightening nut 53 is threaded onto the screw 52. The outer wall of the flange 311 is provided with a slot 312 corresponding to each screw 52. Each screw 52 is engaged in the slot 312 at its corresponding position, and the flange 311 is pressed against the support seat 51 by the hand-tightening nut 53. With this structure, when each hand-tightening nut is loosened and each screw rotates relative to the support seat and moves out of the slot, The electric steering mechanism can be horizontally removed from the slot, which facilitates the disassembly of the electric steering mechanism, steering arm, and propeller from the hull, thus making maintenance of the electric steering mechanism, steering arm, and propeller easier. In addition, when assembling the electric steering mechanism with the hull, simply slide the housing assembly from back to front into the slot and let the housing assembly abut against the support step. Then rotate each screw so that each screw is engaged in the corresponding slot. Finally, tighten the hand nut to press the flange onto the support seat. This allows for the convenient assembly of the electric steering mechanism, steering arm, and propeller with the hull.

[0033] Both the pivot 32 and the steering arm 4 are provided with vertical through holes for the connection wires between the thruster 2 and the controller to pass through vertically. With this structure, the connection wires between the thruster and the controller can be passed through the holes in the pivot and the steering arm, thereby hiding the connection wires to avoid damage and prevent the connection wires from getting tangled.

[0034] A handle 37 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, the electric steering mechanism can be moved out of the opening slot by hand after the electric steering mechanism is released from the hull, thus 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 electric steering mechanism can be moved into the opening slot by hand, and the housing assembly and the hull can be fixed.

[0035] The cruise ship also includes a fixing frame 6; the rear end of the fixing frame 6 is fixed to the upper edge of the propeller 2, and the front end of the fixing frame 6 is provided with a slot 61, in which the middle part of the steering arm 4 is inserted. The fixing frames 6 on both sides of the slot 61 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.

[0036] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. 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.
