[0001] This application relates to the field of marine machinery technology, and in particular to a water propulsion device and a water-mobile device. Background Technology

[0002] Currently, outboard motors can be detached from the support structure connecting to the hull for quick removal and installation. However, after being removed from the hull, the outboard motor requires a special handle to lift it for transport, and this special handle structure results in wasted space on the outboard motor. Utility Model Content

[0003] The embodiments of this application provide a water propulsion device and a water-mobile device.

[0004] The water propulsion device of this application is used to connect to a water carrier to propel the water carrier in water. The water propulsion device includes a main body, an operating device, and a locking module. The end of the main body is provided with a propulsion device for outputting propulsive force to move the water carrier. The operating device is rotatably connected to the end of the main body away from the propulsion device via a transverse connecting shaft, and can be folded or unfolded with the main body. The operating device is used by a user to control the operation of the water propulsion device. The locking module includes a first locking unit and a second locking unit, which are respectively disposed in the operating device and the main body. When the operating device and the main body are folded, the locking module forms a cantilever beam capable of supporting the weight of the main body between the transverse connecting shaft and the locking module through the insertion force between the first locking unit and the second locking unit.

[0005] In some embodiments, the operating device includes an operating lever rotatably connected to the main body of the vessel via the transverse connecting shaft. The main body of the vessel includes a front side facing the water carrier and a rear side facing away from the front side. In the folded state of the operating device and the main body of the vessel, the operating device is folded to the front side of the main body of the vessel, or the operating device is folded to the rear side of the main body of the vessel.

[0006] In some embodiments, when the suspension beam is under the load of the main body of the water propulsion device, the load on the transverse connecting shaft is substantially the same as the load on the locking module.

[0007] In some embodiments, the operating device includes an operating lever, and the locking module further includes a control unit. The first locking unit is disposed on the operating lever, and the second locking unit and the control unit are both disposed on the main body of the device. The control unit includes a movable member that can switch between a first position and a second position. The movable member is coupled to the second locking unit. When the movable member is in the first position, it can control the second locking unit to lock with the first locking unit. When the movable member is in the second position, it allows the second locking unit to unlock from the first locking unit.

[0008] In some embodiments, the locking module further includes a loading member disposed on the main body of the machine body and protruding from the main body of the machine body. The loading member has a loading cavity with an opening at one end. The second locking unit and the control unit are both disposed in the loading cavity. The opening allows the first locking unit to enter and exit the loading cavity to lock or unlock with the second locking unit.

[0009] In some embodiments, the operating lever is provided with a receiving groove, and the first locking unit is housed in the receiving groove. When the operating device and the main body are folded, the loading component extends into the receiving groove, and the first locking unit extends into the loading cavity.

[0010] In some embodiments, the loading component includes a first loading component and a second loading component, which cooperate to form the loading cavity.

[0011] In some embodiments, the first or second loading member is provided with an opening, and the movable member has a portion extending from the opening, the portion of the movable member extending from the opening being able to receive a driving force to cause the movable member to move to the first or second position.

[0012] In some embodiments, the control unit further includes an elastic element that connects the end of the loading cavity and the movable element. The elastic element elastically abuts against the movable element, which is held in the first position by an elastic force. The movable element is displaced to the second position by the driving force, and the elastic element is driven to compress.

[0013] In some embodiments, the locking module further includes a positioning element that controls the movable element to be positioned in the second position.

[0014] In some embodiments, the first locking unit includes a socket, and the second locking unit includes a retractable sliding pin. When the end of the sliding pin extends into the socket and is in a mating engagement state, the operating lever is prohibited from moving towards the unfolded state relative to the main body. When the end of the sliding pin retracts from the socket and is in a disengaged state, the operating lever is allowed to move towards the unfolded state relative to the main body.

[0015] In some embodiments, the movable member can reciprocate within the loading cavity along a first direction, and the sliding pin can reciprocate within the loading cavity along a second direction, which is perpendicular to the first direction. During the transition from an unlocked state to a locked state between the second locking unit and the first locking unit, the sliding pin first moves in the forward direction of the second direction and then moves in the reverse direction. During the transition from a locked state to an unlocked state between the second locking unit and the first locking unit, the sliding pin first moves in the forward direction of the second direction and then moves in the reverse direction.

[0016] In some embodiments, the sliding pins include two pins spaced apart and forming a channel; the insertion holes include two pins, and the two sliding pins are used to engage with the two insertion holes respectively; the movable member includes a first inclined surface and a second inclined surface, the first inclined surface and the second inclined surface being inclined relative to the first direction and in opposite directions; the sliding pin includes a first mating surface and a second mating surface, the first mating surface and the second mating surface being inclined relative to the second direction and in opposite directions. When the movable member moves in the opposite direction along the first direction to enter the channel, the movable member and the sliding pin achieve transmission through the engagement of the first inclined surface and the second inclined surface with the first mating surface and the second mating surface respectively.

[0017] In some embodiments, the loading cavity includes a first cavity and a second cavity that communicate with each other, the second cavity surrounding the first cavity. The movable member is housed in the first cavity and can reciprocate within the first cavity in a first direction. The second locking unit further includes a stop and a reset member. The stop is sleeved on the sliding pin. The reset member is disposed within the second cavity and sleeved on the sliding pin. Both ends of the reset member are connected to the inner wall of the second cavity and the stop, respectively. The reset member is used to provide a force to the sliding pin to move in a second direction through the stop.

[0018] In some embodiments, the control unit further includes an elastic element connecting the inner wall of the loading cavity and the movable member. During the process of the second locking unit switching from an unlocked state to a locked state with the first locking unit, the movable member is moved from the first position to the second position by an external force. The elastic restoring force of the reset member drives the sliding pin to retract into the first cavity. When the movable member is held in the second position, the sliding pin is aligned with the insertion hole, and the external force on the movable member is eliminated, the elastic element drives the movable member to move back from the second position to the first position. The movable member pushes the sliding pin to insert into the insertion hole, and the reset member is elastically compressed by the component force of the elastic element.

[0019] In some embodiments, the water propulsion device includes a connecting assembly that connects to the water carrier. The main body includes a steering seat and a fuselage. The steering seat is connected to the connecting assembly. The fuselage is disposed on a steering shaft rotatably connected to the steering seat. The steering shaft is perpendicular to the transverse connecting shaft and perpendicular to the propulsion direction of the propulsion device. The propulsion device is connected to one end of the fuselage. An operating device is connected to the end of the fuselage away from the propulsion device via the transverse connecting shaft. The operating device rotates relative to the fuselage to a state approximately perpendicular to the steering shaft. The end of the operating device swings around the steering shaft to drive the fuselage to turn around the steering shaft.

[0020] In some embodiments, the steering seat is detachable from the connecting assembly, and after the steering seat is detached from the connecting assembly, the operating device can be folded up to the position where the steering seat is detached from the connecting assembly.

[0021] In some embodiments, the steering seat is provided with a loading member, which is detachably connected to the connecting assembly. The locking module includes a second locking unit disposed on the loading member and a first locking unit disposed on the operating device. After the loading member is detached from the connecting assembly, the operating device drives the first locking unit to approach the loading member, and the first locking unit can lock with the second locking unit.

[0022] In some embodiments, the locking module further includes a control unit and a third locking unit disposed on the loading member. The control unit is coupled to the second locking unit and the third locking unit, and the control unit can drive the second locking unit to lock or unlock with the first locking unit. The connecting component is configured with a fourth locking unit, and the control unit can drive the third locking unit to lock or unlock with the fourth locking unit.

[0023] In some embodiments, the control unit includes a movable member that can switch between a first position and a second position. When the movable member is displaced to the first position and the loading member is assembled with the connecting assembly, the movable member drives the third locking unit to lock with the fourth locking unit. When the movable member is displaced to the second position and the loading member is assembled with the connecting assembly, the movable member can drive the third locking unit to unlock with the fourth locking unit. When the movable member is displaced to the first position and the loading member is detached from the connecting assembly and overlapped with the operating device, the movable member can drive the second locking unit to lock with the first locking unit. When the movable member is displaced to the first position and the loading member is detached from the connecting assembly and overlapped with the operating device, the movable member can drive the second locking unit to unlock with the first locking unit.

[0024] In some embodiments, the locking module locks the operating device to the main body of the fuselage, and when the operating device is supporting the weight of the main body of the fuselage, the center of gravity of the water propulsion device is located below the operating device.

[0025] In some embodiments, the operating device includes a base and a handle extending from the base, the base being connected to the main body via the transverse connecting shaft, the locking module locking the operating device to the main body, the locking module being located on the base away from the transverse connecting shaft, and the handle being used to form a handle for lifting the water propeller.

[0026] In some embodiments, a rotating shaft extends from the end of the base away from the transverse connecting shaft, and a handle is disposed on the rotating shaft, the handle being operable to rotate the rotating shaft. The base is provided with a sensor for sensing the rotation of the rotating shaft, and a circuit board electrically connected to the sensor is also provided within the base. The circuit board processes the rotation sensing data from the sensor and generates an electrical signal that indicates the power level of the water propeller.

[0027] This application also provides a water-based mobile device. The water-based mobile device includes a water-based thruster and a water-based carrier as described in any of the above embodiments, and the main body of the device can be mounted on the water-based carrier.

[0028] In some embodiments, the main body is detachably mounted to the water carrier. With the main body detached from the water carrier, the operating device and the main body are foldable. With the operating device and the main body folded together, and the locking module locking the operating device and the main body, the operating device can function as a handle to suspend the main body laterally.

[0029] In some embodiments, with the fuselage body mounted on the water carrier, the operating device is extended relative to the fuselage body until its end is located within the water carrier, and the operating device is operable.

[0030] The water propulsion device and water-mobile device of this application, in the folded state of the main body and the operating device, the locking module locks the operating device to the main body through the insertion force between the first locking unit and the second locking unit, forming a cantilever structure, so that the operating device can bear the load of the main body. The user can directly lift the operating device horizontally, thereby lifting the entire water propulsion device (i.e., "outboard motor"), without the need to design a special handle structure to lift the water propulsion device, thus avoiding the waste of space on the water propulsion device.

[0046] The embodiments of this application are described in detail below. These embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0047] In the description of the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of the embodiments of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0048] Please see Figures 1 to 5 ,and Figure 9 The water propulsion device 100 of this application embodiment is used to connect to a water carrier 300 to propel the water carrier 300 to move in the water. The water propulsion device 100 includes a main body 10, an operating device 30, and a locking module 50. A propulsion device 20 for outputting propulsive force to move the water carrier 300 is provided at the end of the main body 10. The operating device 30 is rotatably connected to the end of the main body 10 away from the propulsion device 20 via a transverse connecting shaft 40, and can be folded or unfolded with the main body 10. The operating device 30 is used by the user to operate and control the operation of the water propulsion device 100. The locking module 50 includes a first locking unit 51 and a second locking unit 52. The first locking unit 51 and the second locking unit 52 are respectively disposed in the operating device 30 and the main body 10. When the operating device 30 and the main body 10 are folded, the insertion force between the first locking unit 51 and the second locking unit 52 locks the operating device 30 and the main body 10 at the position between the transverse connecting shaft 40 and the propulsion device 20. The operating device 30 forms a cantilever beam between the transverse connecting shaft 40 and the locking module 50 that can bear the weight of the main body 10.

[0049] In the embodiments of this application, the water propulsion device 100 is an outboard motor, and the water carrier 300 is a boat hull for illustrative purposes. In other embodiments, the water propulsion device 100 may also be a pod propulsion device, a stern motor, or a trolley motor; the water carrier may also be a buoy or a rubber buoy.

[0050] Specifically, the water propulsion unit 100 is a detachable power unit that can be installed on the outer side of the hull or stern plate of the water carrier 300 during use, thereby providing power for the operation of the water carrier 300. When not in use, the water propulsion unit 100 can be removed from the water carrier 300 for maintenance and repair.

[0051] The fuselage body 10 is a structure for mounting other components. In this application, the fuselage body 10 is at least used to mount the propulsion device 20. The cross-sectional shape of the fuselage body 10 can be, but is not limited to, circular, elliptical, rectangular, or other polygonal shapes; in this application, the cross-sectional shape of the fuselage body 10 is rectangular. The material of the fuselage body 10 can be plastic or metal. When the fuselage body 10 is made of plastic, it has good insulation performance, low cost, and light weight. When the fuselage body 10 is made of metal, it has high strength, good wear resistance, and a long service life.

[0052] In this application, the fuselage body 10 includes two opposing ends along its extension direction C: a first end 101 and a second end 103. The first end 101 is equipped with a propulsion device 20. When the water propulsion device 100 is installed on the water carrier 300, the propulsion device 20 is at least partially underwater and outputs propulsion force to move the water carrier 300 in the water. The propulsion device 20 includes, but is not limited to, a propeller. It is understood that when the water propulsion device 100 is installed on the water carrier 300, the extension direction C of the fuselage body 10 is substantially perpendicular to the water surface.

[0053] The operating device 30 is for a user to hold while seated inside the water carrier 300 to control the propulsion direction of the underwater propulsion device 20, thereby controlling the direction of travel of the water propulsion unit 100. The operating device 30 is located at the end of the main body 10 furthest from the propulsion device 20 and is rotatably connected to the second end 103 of the main body 10 via a transverse connecting shaft 40. The transverse connecting shaft 40 is perpendicular to the extending direction C of the main body 10, and the operating device 30 can rotate around the transverse connecting shaft 40. During rotation, the extending direction P of the operating device 30 can form different angles with the extending direction C of the main body 10.

[0054] In this application, the direction perpendicular to the extension direction B of the transverse connecting shaft 40 and perpendicular to the extension direction C of the fuselage body 10 is designated as the first direction A, the extension direction of the transverse connecting shaft 40 is designated as the second direction B, and the extension direction C of the fuselage body 10 is designated as the third direction C. It is understood that the rotation plane (plane AC) in which the operating device 30 rotates around the transverse connecting shaft 40 is perpendicular to the transverse connecting shaft 40 (second direction B).

[0055] Furthermore, the operating device 30 and the main body 10 have two states: a folded state and an unfolded state. For the sake of brevity in the following description, they will be collectively referred to as the folded state and unfolded state of the water propulsion device 100.

[0056] The folded state is when the angle formed by the extension direction P of the operating device 30 and the extension direction C of the main body 10 is at its minimum. In this state, the operating device 30 is folded towards the main body 10 and stored near it. Figure 3 As shown. Furthermore, in the folded state, the operating device 30 is locked to the main body 10, preventing the operating device 30 from rotating around the transverse connecting shaft 40. The locked water propeller 100 maintains its folded state, which reduces the space occupied by the water propeller 100, facilitating storage and transportation. Specifically, this application uses a locking module 50 to lock the operating device 30 to the main body 10.

[0057] A locking module 50 is disposed on the main body 10 and the operating device 30. The locking module 50 is located between the two ends of the main body 10, that is, between the transverse connecting shaft 40 and the propulsion device 20. Further, a first locking unit 51 is disposed on the operating device 30, and a second locking unit 52 is disposed on the main body 10. The first locking unit 51 and the second locking unit 52 can be locked together by a plugging force, thereby locking the operating device 30 and the main body 10. When the first locking unit 51 and the second locking unit 52 lock the operating device 30 and the main body 10, the operating device 30 and the main body 10 have two connection positions where the transverse connecting shaft 40 and the first locking unit 51 and the second locking unit 52 are plugged in. The operating device 30 cannot rotate around the transverse connecting shaft 40. Therefore, when the water propulsion device 100 is removed from the water carrier 300, the user can directly carry the entire water propulsion device 100 by hand-carrying the operating device 30. Furthermore, when the water propulsion unit 100 is removed from the water carrier 300 and the user holds the operating device 30, the water propulsion unit 100 is lifted laterally. At this time, the operating device 30 forms a cantilever beam between the lateral connecting shaft 40 and the locking module 50, which can support the weight of the main body 10. Here, "lateral" refers to the direction in which the water propulsion unit 100 is roughly horizontal or at a small angle to the ground after being lifted by the user.

[0058] A cantilever beam typically refers to a beam laterally supported between two ends, one end of which is usually fixed, while the other end is freely extendable or suspended. The cantilever beam bears loads from the freely extendable end. In this application, the cantilever beam can be defined as: the structure formed by the operating lever 33 between the transverse connecting shaft 40 and the locking module 50. The cantilever beam provides supporting loads to the main body 10 when the user carries it by hand. One end of the operating device 30 is connected to the main body 10 via the transverse connecting shaft 40. Between the opposite ends of the operating device 30, the operating device 30 is connected to the main body 10 via the locking module 50, which locks the operating device 30 and the main body 10 together, thereby enabling the operating device 30 to bear the load of the main body 10 and remain stable during hand-carrying operation. At this time, the cantilever beam can bear the weight of the main body 10 and allows the user to directly lift the entire water propeller 100 using the operating device 30 when carrying it. Because the cantilever structure balances the load, it can effectively distribute the load of the main body 10, making the operation more stable and effortless, while avoiding uneven load distribution and preventing local damage to the water propulsion unit 100.

[0059] In the unfolded state, such as Figure 2 , Figure 3 and Figure 4The angle formed by the extension direction P of the operating device 30 and the extension direction C of the main body 10 is greater than the angle formed by the extension direction P of the operating device 30 and the extension direction C of the main body 10 in the folded state. Furthermore, in the unfolded state, the operating device 30 and the main body 10 are not locked together by the locking module 50. In the unfolded state, if the water propeller 100 is installed on the water carrier 300, the user can control the operating device 30 to rotate around the transverse connecting shaft 40, thereby changing the direction of travel of the water propeller 100.

[0060] The operating device 30 is locked to the main body 10 via the locking module 50 to prevent unnecessary movement. At this time, a cantilever structure is formed between the operating device 30 and the main body 10, capable of supporting the weight of the water propeller 100, allowing the user to directly lift the entire water propeller 100 horizontally using the operating device 30. The cantilever structure provides a convenient handling method, reducing the burden of manual lifting, and ensures the water propeller 100 remains stable and secure, increasing safety and stability during transport.

[0061] In the folded state of the main body 10 and the operating device 30, the locking module 50 locks the operating device 30 to the main body 10, forming a cantilever structure. This allows the operating device 30 to bear the load of the main body 10, enabling the user to directly lift the operating device 30 laterally, thereby lifting the entire water propeller 100 (i.e., the "outboard motor"). No special handle structure is needed to carry the water propeller 100, thus avoiding wasted space. The cantilever structure effectively distributes the load of the main body 10, making lifting the water propeller 100 more stable and effortless, while also preventing uneven load distribution and localized damage to the water propeller 100.

[0062] Please see Figures 1 to 5 ,and Figure 9 In some embodiments, the operating device 30 includes an operating lever 33, which is rotatably connected to the main body 10 via a transverse connecting shaft 40. The main body 10 includes a front side facing the water carrier 300 and a rear side opposite to the front side. When the operating device 30 and the main body 10 are folded, the operating device 30 is folded to the front side of the main body 10, or the operating device 30 is folded to the rear side of the main body 10.

[0063] Specifically, the operating lever 33 is rotatably connected to the main body 10 via a transverse connecting shaft 40. The main body 10 includes a front side facing the water carrier 300 and a rear side opposite to the front side. The front and rear sides are opposite sides in the first direction A. When the water propeller 100 is in a folded state, in some embodiments, the operating device 30 is folded to the front side of the main body 10, and in other embodiments, the operating device 30 is folded to the rear side of the main body 10. Regardless of the embodiment, the space occupied by the water propeller 100 can be reduced, facilitating the transportation and storage of the water propeller 100.

[0064] Please see Figure 3 In some embodiments, when the cantilever beam is under the load of the main body 10 of the water propulsion unit 100, the load on the transverse connecting shaft 40 is basically the same as the load on the locking module 50.

[0065] Specifically, the cantilever beam supports the main body 10 of the water propeller 100 under load, which is the state in which the water propeller 100 is lifted laterally by the user. Under load, the lateral connecting shaft 40 and the locking module 50 share the load of the main body 10. "Basically the same" means that the load difference between the lateral connecting shaft 40 and the locking module 50 is less than or equal to a predetermined load, which can be a small value, such as 2N, 5N, 6N, or 10N. The fact that the load on the lateral connecting shaft 40 and the locking module 50 is basically the same ensures that the load is evenly distributed during the lifting and handling of the water propeller 100 by the user. This avoids damage caused by concentrated load on either the lateral connecting shaft 40 or the locking module 50, thereby extending the service life of the water propeller 100 and improving its operational stability. At the same time, having roughly the same load helps the user to handle the water propeller 100 more smoothly when lifting it, avoiding tilting or instability of the water propeller 100 due to uneven load, and improving the safety of the user during handling.

[0066] Please see Figure 1 , Figure 3 , Figures 5 to 9 In some embodiments, the locking module 50 includes a first locking unit 51, a second locking unit 52, and a control unit 53. The first locking unit 51 is disposed on the operating lever 33. The second locking unit 52 and the control unit 53 are both disposed on the main body 10. The control unit 53 includes a movable member 531, which can switch between a first position and a second position. The movable member 531 is coupled to the second locking unit 52. When the movable member 531 is in the first position, it controls the second locking unit 52 to lock with the first locking unit 51. When the movable member 531 is in the second position, it allows the second locking unit 52 to unlock from the first locking unit 51.

[0067] Specifically, the control unit 53 includes a movable member 531, which can switch between a first position and a second position to control the locking and unlocking between the second locking unit 52 and the first locking unit 51, thereby controlling the water propeller 100 to switch between a folded state and an unfolded state. The switching methods include, but are not limited to, sliding and pressing.

[0068] Furthermore, when the movable member 531 is in the first position, such as Figure 8 As shown, the movable element 531 controls the second locking unit 52 to lock with the first locking unit 51. For the sake of brevity in the following description, the state in which the second locking unit 52 and the first locking unit 51 are locked is collectively referred to as the locking state of the locking module 50. When the locking module 50 is in the locked state, the operating lever 33 and the main body 10 are connected at two positions: the transverse connecting shaft 40 and the locking module 50. Therefore, the operating lever 33 cannot rotate freely around the transverse connecting shaft 40, the operating lever 33 is locked to the main body 10, and the operating lever 33 and the main body 10 will not rotate relative to each other. The water propeller 100 remains in a folded state, and the user can directly carry the water propeller 100 for transportation.

[0069] When the movable part 531 is in the second position, such as Figure 7 As shown, the movable element 531 controls the second locking unit 52 to unlock from the first locking unit 51. For the sake of brevity in the following description, the unlocked state of the second locking unit 52 and the first locking unit 51 is collectively referred to as the unlocked state. When the locking module 50 is in the unlocked state, the operating lever 33 is connected to the main body 10 at one position on the transverse connecting axis 40, but not at the locking module 50. Therefore, the operating lever 33 can rotate freely around the transverse connecting axis 40, and the water propeller 100 is in the deployed state. The user can use the deployed operating lever 33 to adjust the direction of travel of the water propeller 100. In the unlocked state, the operating lever 33 no longer bears the weight of the main body 10, thus it is more flexible and easier for the user to operate and adjust.

[0070] Please refer to [link / reference] Figure 1 , Figure 3 , Figures 5 to 9 In some embodiments, the locking module 50 further includes a loading member 55, which is disposed on the main body 10 and protrudes from the main body 10. The loading member 55 has a loading cavity 553 with an opening 555 at one end. The second locking unit 52 and the control unit 53 are both disposed in the loading cavity 553. The opening 555 allows the first locking unit 51 to enter and exit the loading cavity 553 to lock or unlock with the second locking unit 52.

[0071] Specifically, the loading member 55 is provided with a loading cavity 553, which is used to accommodate at least the second locking unit 52 and the control unit 53. The loading member 55 is connected to and protrudes from the main body 10. Exemplarily, the loading member 55 protrudes towards the operating device 30. The protrusion direction of the loading member 55 is a first direction A, which is also the length direction of the loading member 55. The loading member 55 can avoid occupying the internal space of the main body 10, leaving more installation and operation space for other components of the main body 10. Furthermore, the second locking unit 52 and the control unit 53 are housed in the loading member 55, thus being independent of other components of the main body 10, reducing interference with other components, and to a certain extent protecting the surface of the main body 10 from wear or damage that may occur during the operation of the locking module 50, thereby extending the service life of the main body 10.

[0072] One end of the loading cavity 553 has an opening 555, which is located on the rotation path of the first locking unit 51. When the locking module 50 switches from the unlocked state to the locked state, the operating device 30 rotates towards the loading cavity 553, and the first locking unit 51 located on the operating device 30 rotates with the operating device 30. After the first locking unit 51 enters the opening 555, it can lock with the second locking unit 52, thereby the locking module 50 is in the unlocked state; when the locking module 50 switches from the locked state to the unlocked state, the operating device 30 rotates away from the loading cavity 553, thereby the first locking unit 51 leaves the opening 555.

[0073] The loading cavity 553 provides a protective space for the second locking unit 52 and the control unit 53, avoiding direct impact from the external environment (such as moisture or dust in water), and improving the service life of the second locking unit 52 and the control unit 53. The first locking unit 51 can freely enter and exit the loading cavity 553 through the opening 555, ensuring that the locking module 50 can switch between the locked and unlocked states.

[0074] Please continue to refer to this as well. Figure 3 and Figure 5 ,as well as Figures 6 to 8 In some embodiments, the operating lever 33 is provided with a receiving groove 331, and the first locking unit 51 is housed in the receiving groove 331. When the operating device 30 and the main body 10 are folded, the loading member 55 extends into the receiving groove 331, and the first locking unit 51 extends into the loading cavity 553.

[0075] Specifically, the receiving groove 331 is used to accommodate the first locking unit 51. The receiving groove 331 provides a protective space for the first locking unit 51, preventing it from being bumped by external objects. The cross-sectional shape of the receiving groove 331 can be rectangular, circular, or other shapes. Exemplarily, the shape and size of the receiving groove 331 match the outer contour of the loading member 55, thereby allowing the loading member 55 to extend into the receiving groove 331, and the inner wall of the receiving groove 331 can provide a certain guiding and limiting effect on the loading member 55.

[0076] When the operating device 30 needs to be folded with the main body 10, the operating device 30 rotates towards the loading cavity 553, and the loading component 55 extends into the receiving slot 331, which can further reduce the space occupied by the water propeller 100 in the folded state, which is beneficial for users to carry and store. The first locking unit 51 extends into the loading cavity 553 and can lock with the second locking unit 52, thereby keeping the water propeller 100 in the folded state.

[0077] Please see Figure 3 and Figure 5 ,and Figures 6 to 8 In some embodiments, the loading member 55 includes a first loading member 551 and a second loading member 552, which cooperate to form a loading cavity 553.

[0078] Specifically, the first loading member 551 and the second loading member 552 are connected to each other to form a loading cavity 553. In some embodiments, the first loading member 551 and the second loading member 552 are an integral structure, that is, the first loading member 551 and the second loading member 552 are a single unit, thereby improving the bonding strength between the first loading member 551 and the second loading member 552 and preventing separation of the first loading member 551 and the second loading member 552 during the operation of the loading member 55, thus ensuring the stability and reliability of the operation of the loading member 55. In other embodiments, the first loading member 551 and the second loading member 552 are separate structures, that is, the first loading member 551 and the second loading member 552 are two different structures. In one example, the first loading member 551 and the second loading member 552 can be joined together by a detachable connection method, including but not limited to snap-fit ​​connections or threaded connections. In another example, the first loading member 551 and the second loading member 552 can be joined together by a non-detachable connection method, including but not limited to bonding or welding.

[0079] Please see Figure 3 and Figure 5 ,as well as Figures 6 to 8In some embodiments, the first loading member 551 or the second loading member 552 is provided with an opening 557, and the movable member 531 has a portion extending from the opening 557. The portion of the movable member 531 extending from the opening 557 can receive a driving force to cause the movable member 531 to move to a first position or a second position.

[0080] Specifically, the opening 557 is used for a portion of the movable member 531 to extend out. In some embodiments, the first loading member 551 has the opening 557, and in other embodiments, the second loading member 552 has the opening 557. In this application, since the first loading member 551 is located above the second loading member 552, and the opening 557 is located on the first loading member 551, a portion of the movable member 531 is also located above, making it easier for the user to observe and operate. The opening 557 can be one or more; in this application, the number of openings 557 is one, matching the number of movable members 531. More specifically, a portion of the movable member 531 is housed in the loading cavity 553, and another portion extends out from the opening 557. The portion of the movable member 531 extending out from the opening 557 can be held by the user or driven by other external devices. For example, when the user applies a driving force (pushing or pulling the portion extending from the opening 557), the movable member 531 can move within the opening 557, thereby switching between a first position and a second position.

[0081] Please see Figure 3 and Figure 5 ,as well as Figures 6 to 8 In some embodiments, the control unit 53 further includes an elastic element 533. The elastic element 533 connects the end of the loading cavity 553 and the movable element 531. The elastic element 533 elastically abuts against the movable element 531. The movable element 531 is held in a first position by an elastic force. The movable element 531 is displaced to a second position by a driving force, and the elastic element 533 is compressed.

[0082] Specifically, the elastic member 533 is located within the loading cavity 553. One end of the elastic member 533 abuts against the end of the loading cavity 553, and the other end abuts against the movable member 531. The elastic member 533 is used to reset the movable member 531 from the second position to the first position. When the movable member 531 is in the first position, as... Figure 6 and Figure 8 As shown, the elastic element 533 is in a naturally extended state or a slightly compressed state. When the movable element 531 is displaced to the second position by the driving force, from... Figure 6 become Figure 7 In the case of, or from Figure 8 Become Figure 7In the illustrated case, the elastic element 533 is compressed; when the driving force is removed, the elastic element 533 uses its own elastic potential energy to push the movable element 531 back to the first position. The elastic element 533 can be a structure with elastic deformation capability, such as a spring. There can be one or more elastic elements 533. In this application, there are two elastic elements 533, which are located on both sides of the loading cavity 553, respectively, which can provide a smoother driving force for the movable element 531, allowing the movable element 531 to return to the first position more smoothly.

[0083] Please see Figure 4 and Figure 5 ,as well as Figures 6 to 8 In some embodiments, the locking module 50 further includes a positioning element 57, which controls the movable element 531 to be fixed in a second position.

[0084] Specifically, the positioning element 57 is used to fix the movable element 531 in the second position. The positioning element 57 can take various forms, such as an elastic snap, a spring plunger, a mechanical limit block, or a magnetic attraction element. For example, the positioning element 57 can be a spring plunger mounted on the operating lever 33. The spring plunger has a head structure that matches the mating hole or groove of the movable element 531. When the movable element 531 moves to the second position, the head of the spring plunger engages with the mating hole of the movable element 531, thereby achieving positioning. In this way, the positioning element 57 can reliably fix the movable element 531 in the second position, preventing external vibration or accidental interference from causing the movable element 531 to deviate from the second position.

[0085] Please see Figure 1 , Figure 3 , Figure 5 ,as well as Figures 6 to 8 In some embodiments, the first locking unit 51 includes a socket 513, and the second locking unit 52 includes a retractable sliding pin 523. Specifically: when the end of the sliding pin 523 extends into the socket 513 and is in a plugged-in engagement state, the operating lever 33 is prohibited from moving towards the unfolded state relative to the main body 10; when the end of the sliding pin 523 retracts from the socket 513 and is in a disengaged state, the operating lever 33 is allowed to move towards the unfolded state relative to the main body 10.

[0086] Specifically, the insertion hole 513 is installed on the operating lever 33, and the sliding pin 523 is installed on the main body 10. The insertion hole 513 and the sliding pin 523 can form a snap-fit ​​connection. The number of insertion holes 513 and sliding pins 523 can be one or more, and the number of insertion holes 513 and sliding pins 523 can be the same or different. In some embodiments, the locking state is that the sliding pin 523 and the insertion hole 513 are in a plug-in engagement state. When the sliding pin 523 and the insertion hole 513 are in this engagement state, the sliding pin 523 and the insertion hole 513 are plugged in, thereby locking the operating lever 33 and the main body 10. The operating lever 33 cannot rotate freely around the transverse connecting shaft 40; that is, the operating lever 33 and the main body 10 are fixed in a folded state and will not rotate relative to each other. The operating lever 33 and the main body 10 cannot be unfolded, allowing the user to carry the water propeller 100 for transport. At this point, the advantage of the cantilever structure is that the operating lever 33 is connected and locked to the main body 10 of the machine body through the transverse connecting shaft 40, which can effectively share the weight of the main body 10 of the machine body and achieve smooth lifting, reduce instability during manual handling, and enhance ease of use.

[0087] In some embodiments, the unlocked state is characterized by the sliding pin 523 being separated from the socket 513. When the sliding pin 523 is separated from the socket 513, they are not connected. The operating lever 33 is connected to the main body 10 only via the transverse connecting shaft 40. The operating lever 33 can rotate freely around the transverse connecting shaft 40, thus placing the operating lever 33 and the main body 10 in an extended state. The user can use the extended operating lever 33 to adjust the direction of travel of the water propeller 100. In the unlocked state, the operating lever 33 no longer bears the weight of the main body 10, making it more flexible and easier for the user to operate and adjust.

[0088] Please see Figure 1 , Figure 3 , Figure 5 ,as well as Figures 6 to 8 In some embodiments, the movable member 531 can reciprocate within the loading cavity 553 along a first direction A, and the sliding pin 523 can reciprocate within the loading cavity 553 along a second direction B, the second direction B being perpendicular to the first direction A; during the process of the second locking unit 52 and the first locking unit 51 switching from the unlocked state to the locked state, the sliding pin 523 first moves along the positive direction of the second direction B, and then moves along the negative direction of the second direction B; during the process of the second locking unit 52 and the first locking unit 51 switching from the locked state to the unlocked state, the sliding pin 523 first moves along the positive direction of the second direction B, and then moves along the negative direction of the second direction B.

[0089] Specifically, reciprocating movement refers to the repeated linear movement of the movable element 531 or the sliding pin 523 in a predetermined direction. The reciprocating motion of the movable element 531 is driven by user operation or an internal drive mechanism. For example, the reciprocating movement of the movable element 531 can be achieved by manual push-pull by the user or by a spring return structure. The reciprocating movement of the sliding pin 523 can be driven by a spring, gear, or linkage 5313 structure. The reciprocating movement of the movable element 531 occurs along a first direction A, which drives the sliding pin 523 to move synchronously along a second direction B, thereby achieving the switching between the locked state and the unlocked state of the second locking unit 52 and the first locking unit 51 in the locking module 50.

[0090] During the process of switching from the unlocked state to the locked state between the second locking unit 52 and the first locking unit 51, the operating device 30 rotates towards the loading cavity 553. At least a portion of the operating device 30 abuts against the sliding pin 523 during this rotation, applying a driving force to the sliding pin 523 and pushing it to move forward along the second direction B. This forward movement refers to the direction in which the sliding pin 523 retracts into the loading cavity 553 along the second direction. Figures 6 to 8 Regarding the left sliding pin 523, the positive direction of the second direction B is the B1 direction; for Figures 6 to 8 Regarding the right sliding pin 523, the positive direction of the second direction B is direction B2, and the negative direction of the second direction B is direction B1. The operating device 30 continues to rotate towards the loading cavity 553. When the insertion hole 513 aligns with the sliding pin 523, the sliding pin 523 moves in the opposite direction of the second direction B. This reverse movement refers to the direction in which the sliding pin 523 extends outward from the loading member 55 along the second direction. Figures 6 to 8 Regarding the left sliding pin 523, the opposite direction of the second direction B is the B2 direction; for Figures 6 to 8 Regarding the right sliding pin 523, the opposite direction of the second direction B is direction B1. The end of the sliding pin 523 is inserted into the socket 513, forming a plug-in engagement, and the sliding pin 523 and the socket 513 enter a locked state. In the locked state, the inner wall of the socket 513 restricts the relative movement of the sliding pin 523 in the first direction A, thereby locking the operating lever 33 and the main body 10, ensuring that the water propeller 100 remains in a folded state, preventing the water propeller 100 from being accidentally unfolded, and facilitating the user to safely transport the water propeller 100 in the locked state.

[0091] During the transition from the locked state to the unlocked state between the second locking unit 52 and the first locking unit 51, the movement sequence of the sliding pin 523 is the reverse of the above process. The operating device 30 rotates away from the loading cavity 553. During this rotation, the sliding pin 523, under the driving force, first moves in the positive direction of the second direction B, that is, retracts into the loading cavity 553 along the second direction B, thereby gradually withdrawing from the insertion hole 513 and releasing the locked state. Exemplarily, the driving force can be applied by the inner wall of the insertion hole 513 during the rotation of the operating device 30 away from the loading cavity 553, or it can be applied by the movable member 531. Subsequently, the driving force is released, and the sliding pin 523 moves back to its initial position in the reverse direction of the second direction. Figure 6 The position shown (extending from the loading cavity 55) remains in the unlocked state. Figure 6 (As shown). In the unlocked state, the control lever 33 is no longer restricted by the sliding pin 523 and can rotate freely around the transverse connecting shaft 40, thus entering the deployed state. The user can control the direction of travel of the water propulsion device 100 through the deployed control lever 33.

[0092] Please see Figure 1 , Figure 3 , Figure 5 ,as well as Figures 6 to 8 In some embodiments, two sliding pins 523 are included, which are spaced apart and opposite to each other to form a channel 522. Two insertion holes 513 are included, and the two sliding pins 523 are used to engage with the two insertion holes 513 respectively. The movable member 531 includes a first inclined surface 53112 and a second inclined surface 53113, which are inclined relative to a first direction A and in opposite directions. The sliding pin 523 includes a first mating surface 5231 and a second mating surface 5232, which are inclined relative to a second direction B and in opposite directions. When the movable member 531 moves along the opposite direction A1 of the first direction A to enter the channel 522, the movable member 531 and the sliding pin 523 achieve transmission through the engagement of the first inclined surface 53112 and the second inclined surface 53113 with the first mating surface 5231 and the second mating surface 5232 respectively.

[0093] Specifically, there are two sliding pins 523, which are spaced apart and opposite each other to form a channel 522. There are also two insertion holes 513, with each sliding pin 523 engaging with one of the two insertion holes 513. The channel 522 is the movement path of the movable member 531, ensuring that the movable member 531 can enter the channel 522 during its movement in the reverse direction A1 of the first direction A. The reverse movement of the movable member 531 is a movement towards the channel 522 in the first direction A. The channel 522 provides guidance and limiting for the movable member 531. When the movable member 531 moves into the channel 522 in the reverse direction A1 of the first direction A, the first inclined surface 53112 and the second inclined surface 53113 contact the first mating surface 5231 and the second mating surface 5232 of the sliding pin 523, respectively. Since the two are tilted in opposite directions, during the contact process, the movable part 531 will apply a driving force along the second direction B to the sliding pin 523, thereby driving the sliding pin 523 to extend out of the loading part 55 in the opposite direction of the second direction B.

[0094] The interaction between the first mating surface 5231 and the first inclined surface 53112, and between the second mating surface 5232 and the second inclined surface 53113, simplifies the transmission structure. It also utilizes the geometric characteristics of the inclined surface 53111 to improve transmission efficiency and reliability, avoids jamming or poor fit problems that may occur in traditional straight contact, and improves the working stability and service life of the water propeller 100.

[0095] Please see Figure 1 , Figure 3 , Figure 5 ,as well as Figures 6 to 8 In some embodiments, the loading cavity 553 includes a first cavity 5531 and a second cavity 5532 that communicate with each other. The second cavity 5532 surrounds the first cavity 5531. The movable member 531 is housed in the first cavity 5531 and can reciprocate within the first cavity 5531 along a first direction A. The second locking unit 52 also includes a stop member 525 and a reset member 527. The stop member 525 is sleeved on the sliding pin 523. The reset member 527 is disposed within the second cavity 5532 and sleeved on the sliding pin 523. Both ends of the reset member 527 are connected to the inner wall of the second cavity 5532 and the stop member 525, respectively. The reset member 527 is used to provide a force through the stop member 525 to the sliding pin 523 to move in the opposite direction B.

[0096] Specifically, the movable member 531 is housed within the first cavity 5531, and the sliding pin 523 is housed within the second cavity 5532, providing independent spaces for the movable member 531 and the sliding pin 523. A stop member 525 is sleeved on the sliding pin 523 to restrict its movement in the second direction B, preventing it from dislodging from the second cavity 5532. A reset member 527 is disposed within the second cavity 5532 and sleeved on the sliding pin 523, with its two ends connected to the inner wall of the second cavity 5532 and the stop member 525, respectively. The reset member 527 includes, but is not limited to, a spring. The stop member 525 includes, but is not limited to, a retaining ring.

[0097] In one implementation, Figure 6 With the sliding pin 523 not engaged with the socket 513 (operating device 30 unlocked from body 10), the elastic member 533 applies a force A1 in the opposite direction A to the movable member 531, causing the movable member 531 to enter the channel 522 and be in the first position. The first inclined surface 53112 and the second inclined surface 53113 of the movable member 531 engage with the first mating surface 5231 and the second mating surface 5232 respectively, and apply a force to the sliding pin 523, causing the sliding pin 523 to extend from the second cavity 5532 to the outside of the loading member 55. At this time, the stop member 525 and the reset member 527 work together. The reset member 527 is compressed or in a natural state, and the compressed reset member 527 stores its elastic potential energy. Figure 6 The unlock state is switched to Figure 8 During the locked state shown, it will experience Figure 7 In the intermediate state shown, the inner wall of the operating lever 33 presses the sliding pin 523 to retract into the second cavity 5532 along the positive direction of the second direction B. The reset member 527 is stretched, and the first mating surface 5231 and the second mating surface 5232 of the sliding pin 523 respectively mate with the first inclined surface 53112 and the second inclined surface 53113 of the movable member 531, applying a force to the movable member 531. This force causes the movable member 531 to move to the second position along the positive direction A2 of the first direction A. The movable member 531 compresses the elastic member 533, storing its elastic potential energy. When the operating device 30 and the loading member 55 move relative to each other until the sliding pin 523 aligns with the insertion hole 513, as... Figure 8As shown, the force originally applied to the sliding pin 523 by the inner wall of the operating lever 33 disappears, so the reset member 527 resets and shortens in length, driving the sliding pin 523 to move in the opposite direction B2 of the second direction B. At the same time, the elastic potential energy of the elastic member 533 causes the movable member 531 to move in the opposite direction A1 of the first direction A. The movable member 531, through the transmission cooperation of the first inclined surface 53112 and the second inclined surface 53113 with the first mating surface 5231 and the second mating surface 5232 respectively, realizes the transmission of force to the sliding pin 523, pushing the sliding pin 523 to move in the opposite direction of the second direction B until it protrudes outside the loading member 55 and engages with the insertion hole 513. The reset member 527 resets to its original position. Figure 6 In the initial state shown, the operating device 30 is locked to the main body 10.

[0098] Please see Figure 1 , Figure 3 , Figure 5 ,as well as Figures 6 to 8 In some embodiments, during the process of the second locking unit 52 and the first locking unit 51 switching from the unlocked state to the locked state, the movable member 531 is moved from the first position to the second position by an external force. The elastic restoring force of the reset member 527 drives the sliding pin 523 to retract into the first cavity 5531. When the movable member 531 is held in the second position, the sliding pin 523 is aligned with the insertion hole 513, and the external force on the movable member 531 is eliminated, the elastic member 533 is used to drive the movable member 531 to move from the second position back to the first position. The movable member 531 pushes the sliding pin 523 to insert into the insertion hole 513, and the reset member 527 is elastically compressed by the component force of the elastic member 533.

[0099] Specifically, in another embodiment, in Figure 6 With the sliding pin 523 not engaged with the socket 513 (operating device 30 unlocked from body 10), the elastic member 533 applies a force A1 in the opposite direction A to the movable member 531, causing the movable member 531 to enter the channel 522 and be in the first position. The first inclined surface 53112 and the second inclined surface 53113 of the movable member 531 engage with the first mating surface 5231 and the second mating surface 5232 respectively, and apply a force to the sliding pin 523, causing the sliding pin 523 to extend from the second cavity 5532 to the outside of the loading member 55. At this time, the stop member 525 and the reset member 527 work together, and the reset member 527 is compressed, storing its elastic potential energy. Figure 6 The unlock state is switched to Figure 8 During the locked state shown, it will experience Figure 7In the intermediate state shown, the user operates the movable part 531 to move it to the second position along the positive direction A2 of the first direction A. The elastic part 533 is compressed and stores elastic potential energy. The reset part 527 extends and, through the stop part 525, drives the sliding pin 523 to retract into the second cavity 5532 along the positive direction B. At this time, the operating lever 33 and the loading part 55 can approach each other (e.g., Figure 7 As shown), until the sliding pin 523 is aligned with the socket 513 (as shown). Figure 8 As shown, when the driving force applied to the movable member 531 is released, the elastic potential energy stored in the elastic member 533 drives the movable member 531 to move in the opposite direction A1 of the first direction A. The movable member 531, through the transmission engagement of the first inclined surface 53112 and the second inclined surface 53113 with the first mating surface 5231 and the second mating surface 5232 respectively, realizes the transmission of force to the sliding pin 523, pushing the sliding pin 523 to move in the opposite direction B of the second direction until it protrudes out of the loading member 55 and engages with the insertion hole 513. The reset member 527 is then reset to its original position. Figure 6 In the initial state shown, the operating device 30 is locked to the main body 10.

[0100] Please see Figure 1 , Figure 3 , Figure 5 ,as well as Figure 9 In some embodiments, the water propulsion device 100 includes a connecting assembly 70, which can be connected to the water carrier 300. The main body 10 includes a steering seat 11 and a body 13. The steering seat 11 is connected to the connecting assembly 70. The body 13 is disposed on a steering shaft 113 rotatably connected to the steering seat 11. The steering shaft 113 is perpendicular to the transverse connecting shaft 40 and perpendicular to the thrust direction of the propulsion device 20. The propulsion device 20 is connected to one end of the body 13. The operating device 30 is connected to the end of the body 13 away from the propulsion device 20 via the transverse connecting shaft 40. The operating device 30 rotates relative to the body 13 to a state that is approximately perpendicular to the steering shaft 113. The end of the operating device 30 swings around the steering shaft 113 to drive the body 13 to turn around the steering shaft 113.

[0101] Specifically, the water propulsion device 100 includes a connecting assembly 70, which can be connected to the water carrier 300. The main body 10 includes a steering seat 11 and a body 13. The steering seat 11 is connected to the connecting assembly 70, and the body 13 is rotatably connected to the steering seat 11 via a steering shaft 113. The steering shaft 113 is perpendicular to the transverse connecting shaft 40 and perpendicular to the direction of the propulsion force of the propulsion device 20. The propulsion device 20 is mounted at one end of the body 13, and the operating device 30 is connected to the end of the body 13 away from the propulsion device 20 via the transverse connecting shaft 40. The operating device 30 can rotate relative to the body 13 to a state approximately perpendicular to the steering shaft 113. When the end of the operating device 30 swings around the steering shaft 113, the operating device 30 can drive the body 13 to turn around the steering shaft 113. Furthermore, the main body 10 is also equipped with a battery 80, which provides power to the propulsion device 20.

[0102] Please see Figure 1 , Figure 3 , Figure 5 ,as well as Figure 9 In some embodiments, the steering seat 11 is detachable from the connecting assembly 70. After the steering seat 11 is detached from the connecting assembly 70, the operating device 30 can be folded up to the position where the steering seat 11 is detached from the connecting assembly 70.

[0103] Specifically, the steering seat 11 and the connecting component 70 are detachably connected. After the steering seat 11 is detached from the connecting component 70, the operating device 30 can be folded up to the position where the steering seat 11 was originally connected to the connecting component 70, so that the water propeller 100 can maintain a folded state when not in use, thereby reducing the overall space occupied by the water propeller 100 and making it convenient for users to store and carry.

[0104] Please see Figure 1 , Figure 3 , Figure 5 ,as well as Figure 9 In some embodiments, the steering seat 11 is provided with a loading member 55, which is detachably connected to the connecting assembly 70. The locking module 50 includes a second locking unit 52 disposed on the loading member 55 and a first locking unit 51 disposed on the operating device 30. After the loading member 55 is detached from the connecting assembly 70, the operating device 30 drives the first locking unit 51 to approach the loading member 55, and the first locking unit 51 can lock with the second locking unit 52.

[0105] Specifically, in some embodiments, the steering seat 11 is provided with a loading member 55, which is detachably connected to the connecting assembly 70. The locking module 50 includes a second locking unit 52 disposed on the loading member 55 and a first locking unit 51 disposed on the operating device 30. When the loading member 55 is detached from the connecting assembly 70, the operating device 30 can approach the loading member 55 through the first locking unit 51 and lock into place with the second locking unit 52. The arrangement of the locking module 50 allows the operating device 30 to lock into the loading member 55 in the detached state of the steering seat 11, thereby ensuring the stability of the operating device 30 in the stacked state and effectively improving the safety of the device and the user experience.

[0106] Please see Figure 1 , Figure 3 , Figure 5 ,as well as Figure 9 In some embodiments, the locking module 50 further includes a control unit 53 and a third locking unit 58 disposed on the loading member 55. The control unit 53 is coupled to the second locking unit 52 and the third locking unit 58, and the control unit 53 can drive the second locking unit 52 to lock or unlock with the first locking unit 51. The connecting assembly 70 is configured with a fourth locking unit 59, and the control unit 53 can drive the third locking unit 58 to lock or unlock with the fourth locking unit 59.

[0107] Specifically, in some embodiments, the locking module 50 further includes a control unit 53 and a third locking unit 58 disposed on the loading member 55, with the control unit 53 coupled to the second locking unit 52 and the third locking unit 58. A fourth locking unit 59 is disposed on the connecting assembly 70, and the control unit 53 can drive the third locking unit 58 and the fourth locking unit 59 to lock or unlock. By adding the linkage control between the control unit 53 and the third locking unit 58 and the fourth locking unit 59, the loading member 55 can achieve automated locking and unlocking operations in different assembly states, thereby further improving the ease of operation and reliability of the water propulsion device 100.

[0108] Please see Figure 1 , Figure 3 , Figure 5 ,as well as Figure 9In some embodiments, the control unit 53 includes a movable member 531; the movable member 531 can switch between a first position and a second position. When the movable member 531 is displaced to the first position, and the loading member 55 is connected to the connecting assembly 70, the movable member 531 drives the third locking unit 58 and the fourth locking unit 59 to lock together. When the movable member 531 is displaced to the second position, and the loading member 55 is connected to the connecting assembly 70, the movable member 531 can drive the third locking unit 58 and the fourth locking unit 59 to unlock. When the movable member 531 is displaced to the first position, and the loading member 55 is detached from the connecting assembly 70 and overlapped with the operating device 30, the movable member 531 can drive the second locking unit 52 to lock with the first locking unit 51. When the movable member 531 is displaced to the first position, and the loading member 55 is detached from the connecting assembly 70 and overlapped with the operating device 30, the movable member 531 can drive the second locking unit 52 to unlock with the first locking unit 51.

[0109] Specifically, the movable member 531 can switch between a first position and a second position. When the movable member 531 is displaced to the first position and the loading member 55 is in an assembled state with the connecting assembly 70, the movable member 531 can drive the third locking unit 58 to lock with the fourth locking unit 59; when the movable member 531 is displaced to the second position and the loading member 55 is in an assembled state with the connecting assembly 70, the movable member 531 can drive the third locking unit 58 to overlap, and the movable member 531 can drive the second locking unit 52 to lock with the first locking unit 51; when the movable member 531 is displaced to the second position and the loading member 55 is disassembled from the connecting assembly 70 and overlapped with the operating device 30, the movable member 531 can drive the second locking unit 52 to unlock with the first locking unit 51. Through the switching of the movable member 531 to different positions and its driving of the locking units, a stable assembly is achieved between the connecting assembly 70, the steering seat 11, and the operating device 30.

[0110] Please refer to the following: Figure 3 ,as well as Figures 6 to 8 In some embodiments, the locking module 50 locks the operating device 30 to the main body 10, and when the operating device 30 is supporting the main body 10, the center of gravity of the water propulsion unit 100 is located below the operating device 30.

[0111] Specifically, the locking module 50 locks the operating device 30 to the main body 10, and the operating device 30 supports the main body 10 under load as follows: Figure 3As shown, the main body 10 and the operating device 30 are in a folded state. Here, "below" refers to the portion below the operating device 30 (viewed from the long axis P of the operating device) when the user lifts the folded water propeller 100. If the center of gravity of the water propeller 100 is above the operating device 30, it is closer to the user pulling the water propeller 100, making it more difficult for the user to lift. In this embodiment, the center of gravity of the water propeller 100 is below the operating device 30, making it very easy for the user to lift.

[0112] Please refer to the following: Figure 3 and Figure 5 ,as well as Figures 6 to 8 In some embodiments, the operating device 30 includes a base 333 and a handle 335 extending from the base 333. The base 333 is connected to the main body 10 via a transverse connecting shaft 40. The locking module 50 locks the operating device 30 to the main body 10. The locking module 50 is located on the base 333 away from the transverse connecting shaft 40. The handle 335 is used to form a handle for lifting the water propeller 100.

[0113] The operating device 30 includes a base 333 and a handle 335 extending from the base 333. Specifically, the operating lever 33 of the operating device 30 may include a base 333 and a handle 335 extending from the base 333. The base 333 is a component connected to the main body 10. In this disclosure, the base 333 can rotate relative to the main body 10 about a transverse connecting shaft 40 to drive the entire operating device 30 to rotate about the transverse connecting shaft 40. The handle 335 is a component for the user to grip. The handle 335 is directly or indirectly connected to the end of the base 333 away from the main body 10. The handle 335 may be a cylindrical structure for easy gripping. The locking module 50 is located on the base 333 away from the transverse connecting shaft 40 to evenly distribute the load on the operating device 30 in the folded state.

[0114] Please refer to the following: Figure 3 and Figure 5 ,as well as Figures 6 to 8 In some embodiments, a rotating shaft 334 extends from the end of the base 333 away from the transverse connecting shaft 40, and a handle 335 is disposed on the rotating shaft 334, which can control the rotation of the rotating shaft 334. The base 333 is provided with a sensor 339 that senses the rotation of the rotating shaft 334, and a circuit board 337 electrically connected to the sensor 339 is also provided inside the base 333. The circuit board 337 processes the rotation sensing amount of the sensor 339 and generates an electrical signal that can indicate the power of the water propulsion device 100.

[0115] As mentioned earlier, the grip 335 is directly or indirectly connected to the end of the base 333 furthest from the main body 10. In this embodiment, the grip 335 is indirectly connected to the end of the base 333 furthest from the main body 10 via a rotating shaft 334. The grip 335 can control the rotation of the rotating shaft 334. Correspondingly, the sensor 339 detects the angle of rotation of the grip 335 (i.e., the rotation sensing amount). The circuit board 337 processes the angle of rotation detected by the sensor 339 and outputs a control electrical signal to adjust the power of the water propeller 100. Generally, the larger the angle of rotation, the greater the power of the water propeller 100 controlled by the corresponding control electrical signal; the smaller the angle of rotation, the smaller the power of the water propeller 100 controlled by the corresponding control electrical signal.

[0116] This application also provides a water-based mobile device 1000. The water-based mobile device 1000 includes a water-based thruster 100 and a water-based carrier 300 according to any of the above embodiments, and the main body 10 can be mounted to the water-based carrier 300. The beneficial effects of the water-based mobile device 1000 include at least the beneficial effects of the water-based thruster 100, which will not be elaborated here.

[0117] Please see Figure 1 , Figure 3 , Figure 5 ,as well as Figure 9 In some embodiments, the main body 10 is detachably mounted on the water carrier 300. When the main body 10 is detached from the water carrier 300, the operating device 30 and the main body 10 are foldable. With the operating device 30 and the main body 10 folded together and the locking module 50 locking the operating device 30 and the main body 10 together, the operating device 30 can function as a handle to suspend the main body 10 laterally.

[0118] In some embodiments, the main body 10 is detachably mounted to the water carrier 300. When the main body 10 is detached from the water carrier 300, the operating device 30 can be folded together with the main body 10. When the operating device 30 is folded together with the main body 10 and the locking module 50 locks the operating device 30 to the main body 10, the operating device 30 can be used as a handle to suspend the main body 10 laterally. With the above design, in the detached state, the user can easily lift or carry the main body 10 using the folded operating device 30, which not only improves the convenience of carrying, but also ensures safety during transportation through the reliable locking of the locking module 50.

[0119] Please see Figure 1 , Figure 3 , Figure 5 ,as well as Figure 9In some embodiments, when the fuselage 10 is mounted on the water carrier 300, the operating device 30 is extended relative to the fuselage 10 to a position where its end is located within the water carrier 300, and the operating device 30 can be controlled.

[0120] Specifically, when the main body 10 is installed on the water carrier 300, the operating device 30 can be unfolded relative to the main body 10, and the end of the operating device 30 can be located inside the water carrier 300, at which time the operating device 30 can be controlled by the user. By unfolding the operating device 30 to a position inside the water carrier 300, the user can achieve precise control of the main body 10, especially when adjusting the direction or position of the water propeller 100, providing a more intuitive and convenient operating experience, thereby improving the practicality and controllability of the water propeller 100.

[0121] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification. At the same time, other implementation methods can be derived from the above embodiments, so that structural and logical substitutions and changes can be made without departing from the scope of this disclosure.

[0122] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
