Description

Technical Field

[0001] This utility model relates to the field of outboard motor technology, and in particular to a course locking structure, a water propulsion device, and a water mobile device. Background Technology

[0002] The existing manual locking mechanism requires the operator to accurately align the target direction before locking the course. The operator needs to fix the course with one hand and turn the locking switch with the other hand while the outboard motor is moving. The operator needs to complete two actions at the same time (fixing the course and turning the locking switch). This operation method not only increases the difficulty of operation, but also makes it easy for improper operation to cause course deviation or locking failure, affecting navigation safety. Utility Model Content

[0003] This utility model provides a heading locking structure, a water propulsion device, and a water mobile device to solve at least one of the aforementioned technical problems.

[0004] One embodiment of the present invention provides a heading locking structure comprising a base, a movable component, a pin, and a steering shaft. The base is used to connect to one of a waterborne carrier and a power unit. The steering shaft is rotatably engaged with the base and is connected to the other of the waterborne carrier and the power unit, allowing the power unit to turn relative to the waterborne carrier. The steering shaft has an anti-rotation groove along its circumference.

[0005] The movable component is slidably fitted onto the base, the pin is elastically telescopically fitted onto the movable component, and the base has a first latching position and a second latching position;

[0006] When the movable component slides to the second locking position and the pin aligns with one of the anti-rotation slots, the pin extends elastically relative to the movable component, and the movable component drives the end of the pin to engage with the anti-rotation slot;

[0007] When the movable component slides to the second latching position and the pin is misaligned with the anti-rotation groove, the pin is elastically compressed relative to the movable component, and the movable component drives the end of the pin to abut against the steering shaft at a position outside the anti-rotation groove;

[0008] When the movable component slides to the first latching position, the movable component causes the end of the pin to disengage from the anti-rotation groove.

[0009] In the aforementioned heading locking structure, a base is connected to one of the waterborne carrier or the power unit. The steering shaft is rotatably engaged with the base and connected to the other of the waterborne carrier or the power unit, allowing the power unit to steer relative to the waterborne carrier. An anti-rotation groove is formed on the steering shaft in the circumferential direction. A movable component is slidably engaged with the base. A pin is elastically extendable and retractable with the movable component. The base has a first locking position and a second locking position. When the movable component slides to the second locking position and the pin aligns with one of the anti-rotation grooves, the pin elastically extends relative to the movable component. The movable component drives the end of the pin to engage with the anti-rotation groove, thereby preventing the steering shaft from rotating relative to the base. This prevents the power unit from turning relative to the water carrier, thus locking the turning angle of the power unit relative to the water carrier. When the movable component slides to the second locking position and the pin is misaligned with the anti-rotation groove, the pin is elastically compressed relative to the movable component. The movable component drives the end of the pin to abut against the steering shaft outside the anti-rotation groove. At this time, adjusting the steering shaft relative to the base until the anti-rotation groove aligns with the pin allows the pin to extend into the anti-rotation groove under the action of the elastic element. When the movable component slides to the first locking position, the movable component drives the end of the pin to disengage from the anti-rotation groove. At this time, the locking function is closed, thus making the operation simple, efficient, and improving navigation safety.

[0010] In some embodiments, multiple anti-rotation grooves are provided, and the multiple anti-rotation grooves are arranged in an array around the circumferential sidewall of the steering shaft.

[0011] In some embodiments, the movable component includes an elastic element and an actuating element, one end of the elastic element being connected to the base and the other end being connected to the pin, the elastic element being used to drive the pin to connect to the steering shaft;

[0012] The actuating element is connected to the end of the pin near the elastic element, and the actuating element is used to drive the pin away from the steering shaft.

[0013] In some embodiments, the actuating element includes a lever and a paddle, the lever being connected to one side of the paddle, and the lever being able to move the paddle under the action of an external force.

[0014] In some embodiments, the lever includes a connecting portion and a locking portion, the connecting portion connecting the lever and the locking portion, and the locking portion being used to lock into the first locking position and the second locking position;

[0015] The lever drives the connecting part to slide, and the connecting part can drive the locking part to move from the first locking position to the second locking position or from the second locking position to the first locking position.

[0016] In some embodiments, the base includes a housing and a cover plate, the cover plate being connected to one end of the housing, the cover plate having an opening through which the lever passes, and the opposite sides of the lever abutting against the opposite side walls of the opening.

[0017] In some embodiments, the width of the lever is smaller than the width of the opening.

[0018] In some embodiments, the opening has a first sidewall and a second sidewall, the first sidewall and the second sidewall being disposed opposite each other in the width direction of the opening;

[0019] When the lever abuts against the first side wall, the locking part is located in the first locking position;

[0020] When the lever abuts against the second side wall, the locking part is located in the second locking position.

[0021] An embodiment of the present invention provides a water propulsion device comprising a fuselage, a power unit, a connector, and a heading lock structure as described in any of the above embodiments. The power unit is fixed to the fuselage, the fuselage is connected to the connector, the connector is used to connect to a water carrier, the base is connected to one of the fuselage and the connector, and the steering shaft is connected to the other of the fuselage and the connector.

[0022] The base is fixed to one of the fuselage and the connecting member, and the other of the fuselage and the connecting member is detachably connected to the steering shaft;

[0023] The steering shaft is fixed to one of the fuselage and the connecting member, and the other of the fuselage and the connecting member is detachably connected to the base;

[0024] The connector includes a clamp fixed to the water carrier and a rotating bracket rotatably connected to the clamp. The rotating bracket rotates relative to the clamp about a lifting shaft perpendicular to the steering axis.

[0025] In the aforementioned water propulsion device, a base is connected to one of the water carrier and the power unit. A steering shaft is rotatably fitted to the base and connected to the other of the water carrier and the power unit, allowing the power unit to steer relative to the water carrier. The steering shaft has a circumferential anti-rotation groove. A movable component is slidably fitted to the base. A pin is elastically telescopically fitted to the movable component. The base has a first locking position and a second locking position. When the movable component slides to the second locking position and the pin aligns with one of the anti-rotation grooves, the pin elastically extends relative to the movable component. The movable component drives the end of the pin to engage with the anti-rotation groove, thereby preventing the steering shaft from rotating relative to the base. This prevents the power unit from turning relative to the water carrier, thus locking the turning angle of the power unit relative to the water carrier. When the movable component slides to the second locking position and the pin is misaligned with the anti-rotation groove, the pin is elastically compressed relative to the movable component. The movable component drives the end of the pin to abut against the steering shaft outside the anti-rotation groove. At this time, adjusting the steering shaft relative to the base until the anti-rotation groove aligns with the pin allows the pin to re-enter the anti-rotation groove under the action of the elastic element. When the movable component slides to the first locking position, the movable component drives the end of the pin to disengage from the anti-rotation groove. At this time, the locking function is closed, thus making the operation simple, efficient, and improving navigation safety.

[0026] One embodiment of this utility model provides a water-based mobile device including the water propulsion device described in the above embodiment.

[0027] In the aforementioned mobile aquatic device, a base is connected to one of the aquatic carrier and the power unit. A steering shaft is rotatably fitted to the base and connected to the other of the aquatic carrier and the power unit, allowing the power unit to steer relative to the aquatic carrier. The steering shaft has a circumferential anti-rotation groove. A movable component is slidably fitted to the base. A pin is elastically telescopically fitted to the movable component. The base has a first locking position and a second locking position. When the movable component slides to the second locking position and the pin aligns with one of the anti-rotation grooves, the pin elastically extends relative to the movable component. The movable component drives the end of the pin to engage with the anti-rotation groove, thereby preventing the steering shaft from rotating relative to the base. This prevents the power unit from turning relative to the water carrier, thus locking the turning angle of the power unit relative to the water carrier. When the movable component slides to the second locking position and the pin is misaligned with the anti-rotation groove, the pin is elastically compressed relative to the movable component. The movable component drives the end of the pin to abut against the steering shaft outside the anti-rotation groove. At this time, adjusting the steering shaft relative to the base until the anti-rotation groove aligns with the pin allows the pin to re-enter the anti-rotation groove under the action of the elastic element. When the movable component slides to the first locking position, the movable component drives the end of the pin to disengage from the anti-rotation groove. At this time, the locking function is closed, thus making the operation simple, efficient, and improving navigation safety.

[0045] Please refer to Figures 1 to 8 A heading locking structure 100 according to an embodiment of this utility model includes a base 10, a movable component 12, a pin 14, and a steering shaft 16. The base 10 is used to connect with one of the water carrier (not shown) and a power unit 13. The steering shaft 16 is rotatably engaged with the base 10 and is connected to the other of the water carrier and the power unit 13, allowing the power unit 13 to turn relative to the water carrier. The steering shaft 16 has an anti-rotation groove 20 along its circumference. The movable component 12 is slidably engaged with the base 10, and the pin 14 is elastically telescopically engaged with the movable component 12. The base 10 has a first locking position 22 and a second locking position 24. When the movable component 12 slides to the second locking position 24 and the pin 14 is aligned with one of the anti-rotation grooves 20, the pin 14 elastically extends relative to the movable component 12, and the movable component 12 drives the end of the pin 14 to engage with the anti-rotation groove 20. When the movable component 12 slides to the second locking position 24 and the pin 14 is misaligned with the anti-rotation groove 20, the pin 14 is elastically compressed relative to the movable component 12, and the movable component 12 causes the end of the pin 14 to abut against the steering shaft 16 at a position outside the anti-rotation groove 20. When the movable component 12 slides to the first locking position 22, the movable component 12 causes the end of the pin 14 to disengage from the anti-rotation groove 20.

[0046] In the aforementioned heading locking structure 100, the base 10 is connected to one of the water carrier and the power unit 13. The steering shaft 16 is rotatably engaged with the base 10 and connected to the other of the water carrier and the power unit 13, allowing the power unit 13 to turn relative to the water carrier. The steering shaft 16 has an anti-rotation groove 20 along its circumference. The movable component 12 is slidably engaged with the base 10. The pin 14 is elastically telescopically engaged with the movable component 12. The base 10 has a first locking position 22 and a second locking position 24, such that when the movable component 12 slides to the second locking position 24 and the pin 14 is aligned with one of the anti-rotation grooves 20, the pin 14 elastically extends relative to the movable component 12. The movable component 12 drives the end of the pin 14 to engage with the anti-rotation groove 20, thereby preventing the steering shaft 16 from rotating relative to the base 10, which in turn prevents the power unit 13 from turning relative to the water carrier, thus locking the steering angle of the power unit 13 relative to the water carrier. When the movable component 12 slides to the second locking position 24 and the pin 14 is misaligned with the anti-rotation groove 20, the pin 14 is elastically compressed relative to the movable component 12. The movable component 12 drives the end of the pin 14 to abut against the steering shaft 16 outside the anti-rotation groove 20. At this time, the steering shaft 16 is adjusted to rotate relative to the base 10 until the anti-rotation groove 20 is aligned with the pin 14. This allows the pin 14 to re-enter the anti-rotation groove 20 under the action of the elastic element 32. When the movable component 12 slides to the first locking position 22, the movable component 12 drives the end of the pin 14 to disengage from the anti-rotation groove 20. At this time, the locking function is closed, which makes the operation simple, efficient, and improves the safety of navigation.

[0047] Understandably, when using the heading lock function, the pin 14 generally needs to be directly inserted into the anti-rotation groove 20 of the steering shaft 16. However, because the anti-rotation groove 20 of the steering shaft 16 is located inside the base 10 and is obscured, it is not easy to observe. As a result, when pushing the pin 14, it may not be aligned with the anti-rotation groove 20, so the pin 14 cannot be inserted and it is difficult to control and achieve locking.

[0048] In this embodiment, simply pushing the movable component 12 causes the pin 14 to move forward. If the pin 14 aligns perfectly with the anti-rotation groove 20, it can directly insert into the anti-rotation groove 20 to achieve steering lock. If it is not aligned, there is no need to worry, because the end of the pin 14 will abut against the side wall of the steering shaft 16 that is not aligned with the anti-rotation groove 20, compressing the elastic element 32. At this time, rotating the steering shaft 16 will cause the pin 14 to automatically fall into the anti-rotation groove 20, achieving steering lock. If it is necessary to unlock the steering lock, moving the movable component 12 backward will cause the entire pin 14 to move backward, thus removing the pin 14 from the anti-rotation groove 20, allowing the steering shaft 16 to rotate relative to the base 10.

[0049] Specifically, the base 10 may have a first receiving space 26 and a second receiving space 28, which are arranged adjacent to each other. The movable component 12 is disposed in the first receiving space 26 and slidably connected to the base 10, while the steering shaft 16 is disposed in the second receiving space 28 and rotatably connected to the base 10. An anti-rotation groove 20 is provided on the circumferential sidewall of the steering shaft 16, which is adapted to the end of the pin 14. A first locking position 22 and a second locking position 24 are spaced apart along a straight line within the base 10. The base 10 also has a pin hole 30, which is located between the first receiving space 26 and the second receiving space 28.

[0050] In one example, the base 10 can be connected to a water vehicle, and the steering shaft 16 can be connected to a power unit 13, which can steer relative to the water vehicle.

[0051] In one embodiment, when the movable component 12 slides to the second latching position 24 and the pin 14 is aligned with one of the anti-rotation grooves 20, the pin 14 extends elastically relative to the movable component 12, and the movable component 12 drives the end of the pin 14 through the pin hole 30 to latch into the anti-rotation groove 20. At this time, part of the pin 14 is located in the first receiving space 26, part of the pin 14 is located in the pin hole 30, and the other part of the pin 14 is located in the second receiving space 28.

[0052] In one embodiment, when the movable component 12 slides to the second latching position 24 and the pin 14 is misaligned with the anti-rotation groove 20, the pin 14 is elastically compressed relative to the movable component 12. The movable component 12 drives the end of the pin 14 to abut against the steering shaft 16 outside the anti-rotation groove 20, that is, the end of the pin 14 abuts against the side wall of the steering shaft 16. At this time, part of the pin 14 is located in the first receiving space 26, part of the pin 14 is located in the pin hole 30, and the other part of the pin 14 is located in the second receiving space 28. At this time, adjusting the steering shaft 16 relative to the base 10 to rotate until the anti-rotation groove 20 aligns with the pin 14 can allow the pin 14 to extend back into the anti-rotation groove 20 under the action of the elastic member 32.

[0053] In one embodiment, when the movable component 12 slides to the first latching position 22, the movable component 12 causes the end of the pin 14 to disengage from the anti-rotation groove 20, at which time the pin 14 is located in the first receiving space 26.

[0054] In other words, the base 10 is connected to one of the water carrier or the power unit 13. The steering shaft 16 is rotatably engaged with the base 10. The steering shaft 16 is connected to the other of the water carrier or the power unit 13, allowing the power unit 13 to turn relative to the water carrier. The steering shaft 16 has a circumferential anti-rotation groove 20. The movable component 12 is slidably engaged with the base 10. The pin 14 is elastically telescopically engaged with the movable component 12. The base 10 has a first locking position 22 and a second locking position 24. When the movable component 12 slides to the second locking position 24 and the pin 14 is aligned with one of the anti-rotation grooves 20, the pin 14 elastically extends relative to the movable component 12. The movable component 12 drives the end of the pin 14 to engage in the anti-rotation groove 20, thereby preventing the steering shaft 16 from rotating relative to the base 10, which in turn prevents the power unit 13 from turning relative to the water carrier, thus locking the steering angle of the power unit 13 relative to the water carrier. When the movable component 12 slides to the second locking position 24 and the pin 14 is misaligned with the anti-rotation groove 20, the pin 14 is elastically compressed relative to the movable component 12. The movable component 12 causes the end of the pin 14 to abut against the steering shaft 16 outside the anti-rotation groove 20. At this time, adjusting the steering shaft 16 relative to the base 10 until the anti-rotation groove 20 aligns with the pin 14 allows the pin 14 to re-enter the anti-rotation groove 20 under the action of the elastic element 32. When the movable component 12 slides to the first locking position 22, the movable component 12 causes the end of the pin 14 to disengage from the anti-rotation groove 20. At this time, the locking function is closed, which makes the operation simple, efficient, and improves the safety of navigation.

[0055] Please combine Figure 2 and Figure 5 In some embodiments, multiple anti-rotation grooves 20 are provided, and the multiple anti-rotation grooves 20 are arranged in an array around the circumferential sidewall of the steering shaft 16.

[0056] This allows the pin 14 to be easily inserted into one of the anti-rotation slots 20 to achieve the heading lock function.

[0057] Specifically, in one embodiment, a plurality of anti-rotation grooves 20 are arranged in an array around the circumferential sidewall of the steering shaft 16. When the movable component 12 slides to the second locking position 24 and the pin 14 is misaligned with the anti-rotation groove 20, the pin 14 is elastically compressed relative to the movable component 12. The movable component 12 drives the end of the pin 14 to abut against the steering shaft 16 at a position outside the anti-rotation groove 20. At this time, the steering shaft 16 is adjusted to rotate relative to the base 10 until the anti-rotation groove 20 aligns with the pin 14. This allows the pin 14 to extend into the anti-rotation groove 20 again under the action of the elastic member 32, thereby facilitating the insertion of the pin 14 into one of the anti-rotation grooves 20 to achieve the heading lock function.

[0058] Please combine Figure 2 and Figure 6In some embodiments, the movable component 12 includes an elastic element 32 and an actuating element 34. One end of the elastic element 32 is connected to the base 10, and the other end of the elastic element 32 is connected to the pin 14. The elastic element 32 is used to drive the pin 14 to connect to the steering shaft 16. The actuating element 34 is connected to the end of the pin 14 near the elastic element 32, and the actuating element 34 is used to drive the pin 14 to disengage from the steering shaft 16.

[0059] Thus, one end of the pin 14 can be driven by the elastic element 32 to be inserted into the anti-rotation groove 20 to achieve the heading lock function, and the pin 14 can be disengaged from the steering shaft 16 by the actuating element 34 to close the heading lock function.

[0060] Specifically, the elastic element 32 includes a spring. One end of the elastic element 32 can be connected to the side wall of the first receiving space 26, and the other end can be connected to one end of the pin 14. The other end of the pin 14 can be used to connect to the steering shaft 16 and to be inserted into the anti-rotation groove 20.

[0061] In one embodiment, when the toggle member 34 is moved to the second latching position 24 and the pin 14 is aligned with one of the anti-rotation grooves 20, the elastic member 32 can drive the pin 14 to pop out elastically, so that the other end of the pin 14 passes through the pin hole 30 and is latched into the anti-rotation groove 20, thereby realizing the heading lock function.

[0062] In one embodiment, when the toggle member 34 is moved to the first latch position 22, the toggle member 34 can drive the pin 14 to move so that the pin 14 retracts relative to the elastic member 32 into the first receiving space 26, thereby causing the pin 14 to disengage from the steering shaft 16 to disable the heading lock function.

[0063] Please combine Figure 2 and Figure 6 In some embodiments, the actuating member 34 includes a lever 36 and a paddle 38. The lever 36 is connected to one side of the paddle 38, and the lever 36 can drive the paddle 38 to move under the action of external force.

[0064] Thus, an external force can be applied to the lever 36, causing the lever 36 to move the paddle 38 from the second locking position 24 to the first locking position 22.

[0065] Specifically, the pin 14 may be fitted with a lever 38, and one end of the lever 36 is connected to one side of the lever 38. In one embodiment, an external force can be applied to the lever 36 to move the lever 36 from the second latching position 24 to the first latching position 22.

[0066] Please combine Figures 2 to 7In some embodiments, the lever 38 includes a connecting portion 40 and a locking portion 42. The connecting portion 40 connects the lever 36 and the locking portion 42, and the locking portion 42 is used to lock into a first locking position 22 and a second locking position 24. The lever 36 drives the connecting portion 40 to slide, and the connecting portion 40 can drive the locking portion 42 to move from the first locking position 22 to the second locking position 24 or from the second locking position 24 to the first locking position 22.

[0067] Thus, the paddle 38 can be further engaged with the first engagement position 22 and the second engagement position 24 via the connecting part 40 and the engaging part 42.

[0068] Specifically, the lever 36 can be connected to one side of the connecting part 40, the pin 14 can pass through the connecting part 40, and the locking part 42 is connected to one side of the connecting part 40. In one embodiment, the lever 36 drives the connecting part 40 to slide, and the connecting part 40 can drive the locking part 42 to move from the first locking position 22 to the second locking position 24 or from the second locking position 24 to the first locking position 22.

[0069] Optionally, the pin 14 includes a pin shaft 43 and a pin shoulder 44. The pin shoulder 44 can be sleeved on the end of the pin shaft 43 near the elastic member 32. The pin shaft 43 can be inserted into the anti-rotation groove 20. One end of the elastic member 32 can be sleeved on one end of the pin shaft 43 and abut against the pin shoulder 44. In one example, the lever 36 drives the connecting part 40 to slide, and the connecting part 40 can drive the locking part 42 to move from the second locking position 24 to the first locking position 22. At this time, the locking part 42 can abut against the pin shoulder 44 to compress the elastic member 32. In another example, the lever 36 drives the connecting part 40 to slide, and the connecting part 40 can drive the locking part 42 to move from the first locking position 22 to the second locking position 24. The elastic member 32 can elastically drive the pin shoulder 44 to elastically extend the pin shaft 43.

[0070] Please combine Figure 4 and Figure 7 In some embodiments, the base 10 includes a housing 45 and a cover plate 46. The cover plate 46 is connected to one end of the housing 45 and has an opening 48. A lever 36 passes through the opening 48 and the opposite sides of the lever 36 abut against the opposite side walls of the opening 48.

[0071] In this way, the movement space of the lever 36 can be limited, ensuring that the lever 36 is in the vertical direction, which facilitates the operation of the lever 36.

[0072] Specifically, the elastic element 32, the pin 14, and the steering shaft 16 are all disposed within the housing 45, and the cover plate 46 is connected to one end of the housing 45. In one embodiment, the lever 36 passes through the through-hole 48, and the opposite sides of the lever 36 abut against the opposite side walls of the through-hole 48, which can limit the movement space of the lever 36, ensuring that the lever 36 is in the vertical direction, and facilitating the operation of the lever 36.

[0073] Please combine Figure 7 In some embodiments, the width d of the lever 36 is smaller than the width D of the opening 48.

[0074] This allows lever 36 to slide within opening 48.

[0075] Specifically, in one embodiment, the width d of the lever 36 is smaller than the width D of the opening 48, allowing the lever 36 to slide within the opening 48 in the width direction. In one example, when the lever 36 moves towards the steering shaft 16 in the width direction of the opening 48 until it abuts against the side wall of the opening 48, the pin 14 can connect to the steering shaft 16. In another example, when the lever 36 moves away from the steering shaft 16 in the width direction of the opening 48 until it abuts against the other side wall of the opening 48, the pin 14 can disengage from the steering shaft 16.

[0076] Please combine Figure 2 and Figure 7 In some embodiments, the opening 48 has a first sidewall 50 and a second sidewall 52, which are disposed opposite to each other in the width direction of the opening 48. When the lever 36 abuts against the first sidewall 50, the locking portion 42 is located at the first locking position 22. When the lever 36 abuts against the second sidewall 52, the locking portion 42 is located at the second locking position 24.

[0077] Thus, when the lever 36 abuts against the first side wall 50 and the second side wall 52, the locking part 42 can be locked into the first locking position 22 and the second locking position 24.

[0078] Specifically, in one embodiment, when the lever 36 abuts against the first sidewall 50, the locking part 42 is located in the first locking position 22, and the pin 14 disengages from the steering shaft 16. In another embodiment, when the lever 36 abuts against the second sidewall 52, the locking part 42 is located in the second locking position 24, and the pin 14 connects to the steering shaft 16.

[0079] Please refer to Figures 1 to 8A water propulsion device 200 according to an embodiment of this utility model includes a fuselage 54, a power unit 13, a connecting member 56, and a heading locking structure 100 as described in any of the above embodiments. The power unit 13 is fixed to the fuselage 54, and the fuselage 54 is connected to the connecting member 56. The connecting member 56 is used to connect to a water carrier. A base 10 is connected to one of the fuselage 54 and the connecting member 56, and a steering shaft 16 is connected to the other of the fuselage 54 and the connecting member 56. The base 10 is fixed to one of the fuselage 54 and the connecting member 56, and the other of the fuselage 54 and the connecting member 56 is detachably connected to the steering shaft 16. The steering shaft 16 is fixed to one of the fuselage 54 and the connecting member 56, and the other of the fuselage 54 and the connecting member 56 is detachably connected to the base 10. The connecting member 56 includes a clamp 58 fixed to the water carrier and a rotating bracket 60 rotatably connected to the clamp 58. The rotating bracket 60 rotates relative to the clamp 58 around a lifting shaft perpendicular to the axis of the steering shaft 16.

[0080] In the aforementioned water propulsion device 200, the base 10 is connected to one of the water carrier and the power unit 13. The steering shaft 16 is rotatably engaged with the base 10 and is connected to the other of the water carrier and the power unit 13, allowing the power unit 13 to turn relative to the water carrier. The steering shaft 16 has a circumferential anti-rotation groove 20. The movable component 12 is slidably engaged with the base 10. The pin 14 is elastically telescopically engaged with the movable component 12. The base 10 has a first locking position 22 and a second locking position 24, such that when the movable component 12 slides to the second locking position 24 and the pin 14 is aligned with one of the anti-rotation grooves 20, the pin 14 elastically extends relative to the movable component 12. The movable component 12 drives the end of the pin 14 to engage with the anti-rotation groove 20, thereby preventing the steering shaft 16 from rotating relative to the base 10, which in turn prevents the power unit 13 from turning relative to the water carrier, thus locking the steering angle of the power unit 13 relative to the water carrier. When the movable component 12 slides to the second locking position 24 and the pin 14 is misaligned with the anti-rotation groove 20, the pin 14 is elastically compressed relative to the movable component 12. The movable component 12 drives the end of the pin 14 to abut against the steering shaft 16 outside the anti-rotation groove 20. At this time, the steering shaft 16 is adjusted to rotate relative to the base 10 until the anti-rotation groove 20 is aligned with the pin 14. This allows the pin 14 to re-enter the anti-rotation groove 20 under the action of the elastic element 32. When the movable component 12 slides to the first locking position 22, the movable component 12 drives the end of the pin 14 to disengage from the anti-rotation groove 20. At this time, the locking function is closed, which makes the operation simple, efficient, and improves the safety of navigation.

[0081] Specifically, in one embodiment, the base 10 can be connected to the fuselage 54, and the steering shaft 16 can be connected to the connector 56. In another embodiment, the base 10 can be connected to the connector 56, and the steering shaft 16 can be connected to the fuselage 54.

[0082] In one embodiment, the base 10 can be fixedly connected to the fuselage 54, and the connector 56 can be detachably connected to the steering shaft 16. In another embodiment, the base 10 can be fixedly connected to the connector 56, and the fuselage 54 can be detachably connected to the steering shaft 16.

[0083] The clamp 58 is detachably connected to the body 54, and the rotating bracket 60 is rotatably connected to the clamp 58. The rotating bracket 60 rotates relative to the clamp 58 about the lifting axis centered on the vertical steering axis 16. In one embodiment, the water carrier can be placed between the clamp 58 and the rotating bracket 60, and then the water carrier can be fixed to the connector 56 by rotating the rotating bracket 60.

[0084] One embodiment of this utility model is a water-based mobile device including the water-based thruster 200 described above.

[0085] In the aforementioned water-based mobile equipment, the base 10 is connected to one of the water-based carrier and the power unit 13. The steering shaft 16 is rotatably engaged with the base 10 and connected to the other of the water-based carrier and the power unit 13, allowing the power unit 13 to turn relative to the water-based carrier. The steering shaft 16 has a circumferential anti-rotation groove 20. The movable component 12 is slidably engaged with the base 10. The pin 14 is elastically telescopically engaged with the movable component 12. The base 10 has a first locking position 22 and a second locking position 24, such that when the movable component 12 slides to the second locking position 24 and the pin 14 is aligned with one of the anti-rotation grooves 20, the pin 14 elastically extends relative to the movable component 12. The movable component 12 drives the end of the pin 14 to engage with the anti-rotation groove 20, thereby preventing the steering shaft 16 from rotating relative to the base 10, which in turn prevents the power unit 13 from turning relative to the water-based carrier, thus locking the steering angle of the power unit 13 relative to the water-based carrier. When the movable component 12 slides to the second locking position 24 and the pin 14 is misaligned with the anti-rotation groove 20, the pin 14 is elastically compressed relative to the movable component 12. The movable component 12 drives the end of the pin 14 to abut against the steering shaft 16 outside the anti-rotation groove 20. At this time, the steering shaft 16 is adjusted to rotate relative to the base 10 until the anti-rotation groove 20 is aligned with the pin 14. This allows the pin 14 to re-enter the anti-rotation groove 20 under the action of the elastic element 32. When the movable component 12 slides to the first locking position 22, the movable component 12 drives the end of the pin 14 to disengage from the anti-rotation groove 20. At this time, the locking function is closed, which makes the operation simple, efficient, and improves the safety of navigation.

[0086] Specifically, water-based mobile equipment may include waterborne mobile equipment such as boats.
