[0060] The embodiments of the present disclosure are further described below with reference to the accompanying drawings. In the accompanying drawings, the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions.

[0061] In addition, the embodiments of the present disclosure described below in conjunction with the accompanying drawings are exemplary and are only used to explain the embodiments of the present disclosure, and should not be understood as limiting the present disclosure.

[0062] In the present disclosure, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0063] A propeller converts internal energy or electrical energy into mechanical energy, which is then converted into kinetic energy (i.e., propulsion) through mechanical transmission and a propeller, thereby driving a carrier forward or backward. The carrier is preferably a vessel, such as a water inspection device or a water environment monitoring device. A fixture is typically fixed to the rear of the carrier, and the propeller is then mounted and fixed to the fixture. This ensures that the propeller and carrier are relatively fixed, allowing the propulsion generated by the propeller to fully act on the carrier.

[0064] Because the clamp is relatively inexpensive, has a high structural strength, contains no electronic components, and is highly water-resistant, the clamp and carrier are typically not disassembled. Unlike the clamp, the thruster is more expensive and contains circuit boards, gears, motors, and other components. Therefore, it is generally recommended that users only attach the thruster to the clamp when traveling and only remove the thruster and clamp after the trip to store the thruster separately and avoid shortening its lifespan.

[0065] To secure the thruster to the fixture, the thruster requires a mounting structure that matches the fixture. This mounting structure typically protrudes from the thruster's body, causing the entire thruster to occupy a large space and making it difficult to store the thruster after the trip. Furthermore, the fixture and thruster are often complex, making assembly and disassembly cumbersome for the user, resulting in poor convenience and a poor user experience.

[0066] To address the aforementioned technical issues, referring to Figures 1a-2 , embodiments of the present disclosure provide a propeller 100 comprising a body 10 and a tilting bracket 20. The tilting bracket 20 is configured to be detachably connected to a clamp 200 secured to a carrier. The body 10 is pivotally connected to the tilting bracket 20, allowing the tilting bracket 20 to tilt relative to the clamp 200. After the tilting bracket 20 is released from the clamp 200, it can move relative to the body 10 until it folds with the body 10.

[0067] It is understood that the detachable connection between the tilting bracket 20 and the clamp 200 is preferably achieved by a tool-free method such as plugging, snapping, or cam locking, to facilitate user assembly and disassembly. When in use, the tilting bracket 20 and the clamp 200 remain relatively fixed to prevent the tilting bracket 20 from shaking relative to the clamp 200 and affecting the operation of the propeller 100.

[0068] The rotational connection between the fuselage 10 and the tilting bracket 20 can be a direct connection between the fuselage 10 and the tilting bracket 20, with a revolute pair formed between the fuselage 10 and the tilting bracket 20, thereby achieving relative rotation. Alternatively, the connection can be an indirect connection between the fuselage 10 and the tilting bracket 20, such as by providing an additional component between the fuselage 10 and the tilting bracket 20, with the component forming a revolute pair with the fuselage 10, or with the component forming a revolute pair with the tilting bracket 20, thereby achieving relative rotation between the fuselage 10 and the tilting bracket 20. The relative rotation of the fuselage 10 and the tilting bracket 20 allows the fuselage 10 to tilt relative to the fixture 200, thereby changing the pitch angle of the propulsion force, or changing the height of the fuselage 10 relative to the water surface, thereby allowing the fuselage 10 to break free from the water or be immersed in the water. It is understood that, ideally, if the carrier is not tilted on the water surface, the tilting motion of the fuselage 10 occurs in a vertical plane. However, in general, due to the uneven distribution of gravity of the cargo or people on the carrier, the carrier will be slightly tilted relative to the water surface, causing the tilting motion of the fuselage 10 to not be absolutely vertical, that is, the tilting plane deviates from the vertical plane. Therefore, the definitions of reference planes and reference directions such as vertical plane, horizontal plane, vertical direction, and horizontal direction below are merely for understanding the technical solutions of this disclosure and should not be used to limit this disclosure.

[0069] It is understandable that in the present application, the tilting bracket 20 serves as a mechanism for connecting the fuselage 10 and the clamp 200. In order to provide the fuselage 10 with the freedom to tilt and to be installed in pair with the clamp 200, the tilting bracket 20 needs to have a certain protrusion relative to the fuselage 10. However, it is precisely because the tilting bracket 20 partially protrudes relative to the fuselage 20 that the tilting bracket 20 affects the overall volume of the propeller 100, making it inconvenient to carry. Therefore, in the propeller 100 provided in the embodiment of the present disclosure, after the tilting bracket 20 is separated from the clamp 200, the tilting bracket 20 can move relative to the fuselage 10 until it is folded with the fuselage 10, so that the tilting bracket 20 no longer protrudes, or the protrusion is reduced, thereby reducing the space occupied by the propeller 100, reducing the difficulty of storage, and improving portability. The folding of the tilting bracket 20 and the fuselage 10 can be understood as that after the propeller 100 is removed from the clamp, at least a portion of the tilting bracket 20 is folded with the fuselage 10, achieving a closer spatial position relationship with the fuselage 10 (they can be in contact with each other or have an air gap), so that the propeller as a whole is more spatially regular and easy to carry. The relative movement of the tilting bracket 20 and the fuselage 10 can be a rotational connection between the tilting bracket 20 and the fuselage 10, where the tilting bracket 20 rotates relative to the fuselage 10 until it folds with the fuselage 10. The relative movement of the tilting bracket 20 and the fuselage 10 can also be a sliding connection between the tilting bracket 20 and the fuselage 10, where the tilting bracket 20 slides relative to the fuselage 10 until it folds with the fuselage 10. Of course, the relative movement of the tilting bracket 20 and the fuselage 10 can also be understood as a combination of rotation and sliding of the tilting bracket 20 relative to the fuselage 10 until it folds with the fuselage 10.

[0070] Therefore, by configuring the tilting bracket 20 to be movable relative to the body 10 and folded with the body 10 after being released from the clamp 200, the tilting bracket 20 can be stored, thereby reducing the space occupied by the entire propeller 100. Furthermore, the tilting bracket 20 and the clamp 200 are detachably connected, making it easy to disassemble and assemble the tilting bracket 20 and the clamp 200 before and after use of the propeller 100, thereby improving convenience and enhancing the user experience.

[0071] The fuselage 10 of the propeller 100 provided by the present disclosure is described in detail below.

[0072] In the propeller 100 provided in one embodiment of the present disclosure, please continue to refer to Figures 1a to 2. The fuselage 10 includes an above-water portion 11a and an underwater portion 11b. The above-water portion 11a refers to the portion of the fuselage 10 that is exposed above the water surface when the propeller 100 is in use, and the underwater portion 11b refers to the portion of the fuselage 10 that is immersed below the water surface when the propeller 100 is in use. A lifting bracket 20 is installed on the horizontal side of the above-water portion 11a, and the underwater portion 11b is equipped with a motor 13 and a propeller 14. The motor 13 and the propeller 14 are connected and are used to drive the propeller 14 to rotate to generate propulsion. The lifting bracket 20 is installed on the above-water portion 11a to facilitate the installation of the lifting bracket 20 and the clamp 200.

[0073] In one embodiment, referring to Figures 1a to 2 , a control circuit board 15 and a battery 16 are further disposed within the fuselage 10. The battery 16 and the motor 13 are both electrically connected to the control circuit board 15. The control circuit board 15 is used to control the battery 16 to power the motor 13 and to control the operation of the motor 13. Specifically, the control circuit board 15 includes a central controller 15a and a drive controller 15b. The central controller 15a communicates with the drive controller 15b and the battery 16 via conductive cables. This allows the central controller 15a to receive status information from the battery 16, the drive controller 15b, and the motor 13. This allows for integrated control based on the respective operating states of the battery 16, the drive controller 15b, and the motor 13 to optimize their operating conditions. Specifically, the central controller 15a can control the battery 16 to power the motor 13. The drive controller 15b controls the operation of the motor 13, enabling the motor 13 to cooperate with the propeller 14 to generate propulsion. In addition to powering the motor 13, the battery 16 can also power the electronic components in the fuselage 10, such as the central controller 15a and the drive controller 15b, to ensure their normal operation. The central controller 15a can receive signals sent by the user and perform related actions, such as increasing the speed of the motor 13 through the drive controller 15b. The battery 16 can be partially placed in the underwater part 11b and partially in the above-water part 11a, or completely in the underwater part 11b or the above-water part 11a. The control circuit board 15 is preferably placed in the above-water part 11a. It can be understood that by arranging the battery 16 inside the fuselage 10, all the wiring related to the battery 16 is hidden inside the fuselage 10, which can reduce external wiring and improve safety of use. When the battery 16 needs to be charged, the thruster 100 needs to be removed from the fixture 200 and taken indoors or elsewhere for recharging. This is when the detachable connection between the tilting bracket 20 and the fixture 200 becomes even more advantageous. Because the tilting bracket 20 and the fixture 200 are detachably connected, the thruster 100 can be quickly removed from the fixture 200 for recharging. Furthermore, because the tilting bracket 20 can be moved relative to the body 10 until it folds with the body 10 for storage, the overall space occupied by the thruster 100 is reduced. During recharging, the thruster 100 does not take up excessive space, thus avoiding inconvenience for the user.

[0074] In one embodiment, referring to Figures 1a to 2 , the fuselage 10 includes a main fuselage body 11 and a steering bracket 12. The portion of the main fuselage body 11 that is above the water surface is the above-water portion 11a, and the portion of the main fuselage body 11 that is submerged in the water is the submerged portion 11b. The steering bracket 12 is disposed on the horizontal side of the above-water portion 11a. A steering shaft 81 is disposed between the main fuselage body 11 and the steering bracket 12. The main fuselage body 11 is rotatably connected to the steering bracket 12 via the steering shaft 81, allowing the main fuselage body 11 to rotate relative to the steering bracket 12 about the axis of the steering shaft 81. For ease of description, the axis of the steering shaft 81 is defined as the first axis 91. It will be understood that the steering shaft 81 can be fixed to one of the main fuselage body 11 or the steering bracket 12 and rotatably engage with the other. The steering freedom provided by the steering shaft 81 allows the propeller 14 to change its orientation in the horizontal plane, thereby changing the vehicle's travel direction, for example, turning left or right.

[0075] Furthermore, the propeller 100 also includes a tilting shaft 82, which is arranged between the steering bracket 12 and the tilting bracket 20 to allow the tilting bracket 20 to rotate relative to the steering bracket 12 around the axis of the tilting shaft 82 through the tilting shaft 82. For ease of description, the axis of the tilting shaft 82 is defined as the second axis 92, and the first axis 91 and the second axis 92 are perpendicular. It can be understood that there are two situations in which the first axis 91 and the second axis 92 are perpendicular. One is that the first axis 91 and the second axis 92 intersect and form a 90-degree angle. The other is that the first axis 91 and the second axis 92 are not on the same plane, but there is a straight line parallel to the first axis 91 that intersects with the second axis 92 and forms a 90-degree angle. The tilting shaft 82 can be fixed to one of the steering bracket 12 and the tilting bracket 20, and rotate with the other of the steering bracket 12 and the tilting bracket 20. Preferably, when the propeller 100 is in normal operation, the second axis 92 extends generally horizontally, and the first axis 91 is parallel to the tilting surface (i.e., a generally vertical surface). By providing the steering bracket 12, the steering axis 81 between the steering bracket 12 and the fuselage body 11, and the tilting axis 82 between the steering bracket 12 and the tilting bracket 20, the structure is simplified while allowing the fuselage body 11 to have both tilting and steering freedoms.

[0076] Specifically, referring to Figures 1a, 3, and 4a, the steering bracket 12 defines a steering shaft hole 201 and a tilting shaft hole 202. The tilting shaft 82 is disposed on the tilting bracket 20 and rotatably engages with the tilting shaft hole 202. The steering shaft 81 is disposed on the main body 11 and rotatably engages with the steering shaft hole 201. In this embodiment, there are two steering shaft holes 201, one on each side of the steering bracket 12 in the vertical direction. There are also two steering shafts 81, one end of which is fixed to the main body 11, and the other end of which extends into the corresponding steering shaft hole 201 for rotational engagement. The first axes 91 of the two steering shafts 81 coincide. The tilting shaft hole 202 extends horizontally and penetrates the steering bracket 12. There are two tilting shafts 82, one extending from each side of the tilting shaft hole 202 and rotatably engages with the tilting shaft hole 202. The steering bracket 12 is in the shape of a cross formed by two rods that cross and are perpendicular to each other, and is a four-way structure.

[0077] In other embodiments, the number of the steering shaft 81 and the tilting shaft 82 can both be one, or the number of the steering shaft 81 can be one and the number of the tilting shaft 82 can be two, or the number of the steering shaft 81 can be two and the number of the tilting shaft 82 can be one. The steering bracket 12 as a whole can also have other shapes. This disclosure does not limit the number of the tilting shafts 82 and steering shaft 81, nor the shape of the steering bracket 12.

[0078] In another embodiment, see Figure 4b . Compared to the previous embodiment, the difference lies in the arrangement of the tilting shaft 82 and the tilting shaft hole 202. In this embodiment, the tilting shaft 82 is fixed to the steering bracket 12 and is rotatably connected to the tilting bracket 20. Specifically, the tilting shaft 82 and the steering bracket 12 are integrally formed. The tilting bracket 20 defines two tilting shaft holes 202, with the ends of the tilting shaft 82 extending into the two tilting shaft holes 202 for rotational engagement. The centerlines of the two tilting shaft holes 202 coincide and both extend horizontally.

[0079] In the two embodiments described above, see Figures 4a and 4b . The steering shaft holes 201 are both provided on the steering bracket 12, and the steering shaft 81 is configured to be fixed to the main body 11. In other embodiments, see Figures 4c and 4d . Alternatively, the steering shaft holes 201 may be provided on the main body 11, with the steering shaft 81 fixed to the steering bracket 12. Specifically, there are two steering shaft holes 201, each located on opposite sides of the steering bracket 12. There are two steering shafts 81, one end of which is fixed to the steering bracket 12, and the other end of which extends into a corresponding steering shaft hole 201 for rotational engagement. Alternatively, there is one steering shaft 81, one end of which is rotationally engaged with one steering shaft hole 201, and the other end of which is rotationally engaged with the other steering shaft hole 201. The differences between the embodiments illustrated in Figures 4c and 4d are the same as those between the embodiments illustrated in Figures 4a and 4b , namely, the arrangement of the tilting shaft 82 and tilting shaft hole 202, which will not be further described here.

[0080] The following is a detailed description of the storage solution for the tilting bracket 20 of the propeller 100 provided in the present disclosure.

[0081] In one embodiment of the present disclosure, referring to Figures 1b, 4a, and 5, a tilting shaft 82 is provided between the body 10 and the tilting bracket 20. The body 10 is rotatably connected to the tilting bracket 20 via the tilting shaft 82. After the tilting bracket 20 is released from the clamp, the tilting bracket 20 can be rotated relative to the body 10 via the tilting shaft 82 until it folds with the body 10. It will be appreciated that when in use, the body 10 can be tilted relative to the tilting bracket 20 using the tilting shaft 82. When not in use, after the tilting bracket 20 is removed from the clamp, the tilting bracket 20 can also be rotated relative to the body 10 using the tilting shaft 82 for storage. In this embodiment, both the tilting of the body 10 and the storage of the tilting bracket 20 are achieved via the tilting shaft 82, which significantly simplifies the structure of the tilting bracket 20 and the body 10, reducing costs while also maintaining good structural strength.

[0082] In one embodiment of this embodiment, referring to Figures 4a and 5, a tilting shaft 82 is fixedly mounted on the tilting bracket 20, and a tilting shaft hole 202 is defined in the fuselage 10. The tilting shaft 82 is rotatably engaged with the tilting shaft hole 202. Specifically, the tilting shaft hole 202 is defined in and passes through the steering bracket 12. There are two tilting shafts 82, which extend from either side of the tilting shaft hole 202 and rotatably engage with the tilting shaft hole 202. This allows the tilting bracket 20 to rotate relative to the steering bracket 12 about a second axis 92 via the two tilting shafts 82 and the tilting shaft hole 202. The second axis 92 is perpendicular to the first axis 91.

[0083] In another embodiment of this embodiment, please refer to Figure 4b. Compared with the previous embodiment, the difference lies in the arrangement of the tilting shaft 82 and the tilting shaft hole 202. The tilting shaft 82 in this embodiment is fixedly mounted on the fuselage 10, and the tilting bracket 20 defines a tilting shaft hole 202. The tilting shaft 82 rotates in conjunction with the tilting shaft hole 202. Specifically, the tilting shaft 82 is fixed to the steering bracket 12, and the tilting bracket 20 defines two tilting shaft holes 202. The two ends of the tilting shaft 82 extend into the two tilting shaft holes 202 for rotational engagement. This allows the tilting bracket 20 to rotate relative to the steering bracket 12 around the second axis 92 via the tilting shaft 82 and the tilting shaft hole 202. The second axis 92 is perpendicular to the first axis 91.

[0084] In one embodiment of this embodiment, as shown in FIG6 , a first bearing 31 is disposed within the tilting shaft hole 202. The outer ring of the first bearing 31 is fixed to the inner wall of the tilting shaft hole 202, while the inner ring of the first bearing 31 is fixed to the tilting shaft 82. Specifically, the first bearing 31 may be a deep groove ball bearing, a needle roller bearing, a thrust roller bearing, or other similar bearing. The outer circumferential surface of the outer ring of the first bearing 31 is in contact with and relatively fixed to the inner wall of the tilting shaft hole 202, while the inner circumferential surface of the inner ring of the first bearing 31 is in contact with and relatively fixed to the outer wall of the tilting shaft 82. Due to the rollers disposed between the outer and inner rings, the outer and inner rings of the first bearing 31 can rotate relative to each other in the circumferential direction while being relatively fixed in the axial direction. This arrangement significantly reduces friction, thereby simplifying the control of the tilting operation. Furthermore, the first bearing 31 facilitates axial fixation between the components housing the tilting shaft 82 and the components housing the tilting shaft hole 202, such as the tilting bracket 20 and the steering bracket 12 in this embodiment. In addition, the first bearing 31 is preferably set to adapt to the number of the tilting shafts 82. For example, in the present embodiment, the number of first bearings 31 is two, corresponding to two tilting shafts 82. However, in other embodiments, when the length of the tilting shaft 82 and the tilting shaft hole 202 is longer, multiple first bearings 31 can also be set to correspond to one tilting shaft 82. The embodiment of the present disclosure does not limit the number of first bearings 31.

[0085] In one embodiment of the present disclosure, referring to Figures 7a to 9, a tilting shaft 82 is provided between the body 10 and the tilting bracket 20. The body 10 is rotatably connected to the tilting bracket 20 via the tilting shaft 82, allowing the body 10 to rotate relative to the tilting bracket 20 about a second axis 92. A storage shaft 83 is provided between the tilting shaft 82 and the tilting bracket 20. The tilting bracket 20 is rotatably connected to the tilting shaft 82 via the storage shaft 83. After the tilting bracket 20 is released from the clamp 200, the tilting bracket 20 can be rotated relative to the tilting shaft 82 about the axis of the storage shaft 83 via the storage shaft 83 until it is folded with the body 10. For ease of description, the axis of the storage shaft 83 is defined as a third axis 93, which is perpendicular to the second axis 92. Taking into account manufacturing tolerances and assembly tolerances, the angle formed by the second axis 92 and the third axis 93 is generally not exactly 90 degrees. Therefore, as long as the angle formed by the second axis 92 and the third axis 93 is close to 90 degrees, the second axis 92 and the third axis 93 can be considered perpendicular. Similarly, the determination of whether the first axis 91 and the second axis 92 are perpendicular can also be made in the same way. Preferably, when in use (i.e., when the tilting bracket 20 is installed in the fixture), the first axis 91 and the third axis 93 are parallel and both are perpendicular to the second axis 92. It is understood that when in use, the body 10 can be tilted relative to the tilting bracket 20 using the tilting shaft 82. When not in use, after the tilting bracket 20 is removed from the fixture 200, the tilting bracket 20 can be rotated relative to the body 10 using the storage shaft 83 to complete storage. In this embodiment, the tilting bracket 20 can be stowed by rotating about the third axis 93 using the stowage shaft 83, by rotating about the second axis 92 using the stowage shaft 82, or by rotating about both the third axis 93 and the second axis 92 using the stowage shaft 83 and the stowage shaft 82. Thus, the tilting bracket 20 has multiple stowage methods, making stowage more convenient. Furthermore, in this embodiment, the tilting bracket 20 can also be used in situations where stowage using the stowage shaft 82 is not possible. For example, due to the structure of the body 11, the tilting bracket 20 cannot be rotated about the second axis 92 relative to the body 11 to fold with the body 11, or the tilting bracket 20 can only be partially stowed. In such cases, the presence of the stowage shaft 83 provides an alternative stowage method for the tilting bracket 20, namely, rotation about the third axis 93 relative to the body 11 to better fold with the body 11, thus providing greater applicability. Therefore, in this embodiment, the requirements for the structure of the main body 11 are relatively low, and the embodiment can be applied to main bodies 11 of various shapes.

[0086] In one embodiment of this embodiment, please continue to refer to Figures 7a to 9. The storage shaft 83 is fixedly set on the tilting bracket 20, and the tilting shaft 82 is provided with a storage shaft hole 203. The storage shaft 83 rotates with the storage shaft hole 203. Specifically, the steering bracket 12 is provided with a tilting shaft hole 202, and one end of the tilting shaft 82 extends into the tilting shaft hole 202 for rotational engagement. The other end of the tilting shaft 82 is provided with a storage shaft hole 203 for the storage shaft 83 to extend into for rotational engagement. With this arrangement, after the tilting bracket 20 is detached from the clamp 200, the degrees of freedom provided by the storage shaft 83 and the degrees of freedom provided by the tilting shaft 82 will not be constrained, thereby retaining the diversity of the storage methods of the tilting bracket 20.

[0087] Further, referring to Figure 10 , both ends of the storage shaft 83 are fixed to the tilting bracket 20, and the portion between the ends of the storage shaft 83 is accommodated in the storage shaft hole 203. Specifically, the tilting bracket 20 extends in a direction perpendicular to the third axis 93 to constrain the storage shaft 83 in the storage shaft hole 203, thereby maintaining the relative connection between the tilting bracket 20 and the tilting shaft 82.

[0088] In another embodiment of this embodiment, please refer to Figures 11 and 12. Compared with the previous embodiment, the difference lies in the setting of the storage shaft 83 and the storage shaft hole 203. In this embodiment, the storage shaft 83 is fixedly set on the tilting shaft 82, and the tilting bracket 20 is provided with a storage shaft hole 203, and the storage shaft 83 rotates with the storage shaft hole 203. Specifically, both ends of the storage shaft 83 are provided with radially extending bosses 831, and the part between the two ends of the storage shaft 83 is accommodated in the storage shaft hole 203 to be rotatably connected with the tilting bracket 20. The bosses 831 at both ends of the storage shaft 83 can restrain the axial movement of the tilting bracket 20 relative to the tilting shaft 82, so that the tilting bracket 20 and the tilting shaft 82 maintain relative positions. The two bosses 831 can be nuts, nuts, and of course they can also be limiting structures such as flanges or limit pins.

[0089] In another embodiment of this embodiment, see Figures 13 and 14 . This embodiment differs from the previous embodiment in the arrangement of the receiving shaft 83 and the receiving shaft hole 203. In this embodiment, a second bearing 32 is positioned within the receiving shaft hole 203. The outer ring of the second bearing 32 is fixed to the inner wall of the receiving shaft hole 203, while the inner ring of the second bearing 32 is fixed to the receiving shaft 83. Specifically, the outer circumferential surface of the outer ring of the second bearing 32 abuts against and is relatively fixed to the inner wall of the receiving shaft hole 203, while the inner circumferential surface of the inner ring of the second bearing 32 abuts against and is relatively fixed to the outer wall of the receiving shaft 83. Rollers are positioned between the outer and inner rings, allowing the outer and inner rings of the second bearing 32 to rotate relative to each other in the circumferential direction while remaining relatively fixed in the axial direction. As will be appreciated, this arrangement significantly reduces friction. Furthermore, the second bearing 32 ensures that the tilting bracket 20 and the receiving shaft 83 are relatively fixed about the third axis 93. In this embodiment, since the second bearing 32 needs to bear the gravity of the fuselage 10 after the lifting bracket 20 is installed on the clamp, the axial load bearing capacity of the second bearing 32 is required to be high. Therefore, the second bearing 32 is preferably a thrust ball bearing or a thrust roller bearing with better axial load bearing capacity.

[0090] In yet another embodiment of this embodiment, see Figures 15 and 16 . Compared to the previous embodiment, this embodiment differs in the arrangement of the storage shaft 83 and the storage shaft hole 203. In this embodiment, the storage shaft 83 is rotatably connected to the tilting bracket 20, allowing the tilting bracket 20 to rotate relative to the storage shaft 83 about a third axis 93 until it folds with the body 10. The storage shaft 83 is rotatably connected to the tilting shaft 82, allowing the body 10 to rotate relative to the storage shaft 83 about a second axis 92 for tilting. It will be appreciated that in the previous embodiment, the tilting shaft 82 is fixed to the storage shaft 83 and rotatably connected to the steering bracket 12 of the body 10. In contrast, in this embodiment, the tilting shaft 82 is rotatably connected to the storage shaft 83, and the tilting shaft 82 is fixed to the steering bracket 12, allowing the body 10 to rotate freely relative to the storage shaft 83 about the second axis 92. In other embodiments, the tilting shaft 82 may also be rotatably connected to the storage shaft 83 at one end and rotatably connected to the steering bracket 12 at the other end, thereby also achieving the tilting of the fuselage 10 .

[0091] Further, referring to Figures 15 and 16, the tilting bracket 20 defines a receiving shaft hole 203, with the receiving shaft 83 rotatably engaged with the receiving shaft hole 203. The receiving shaft 83 defines a tilting shaft hole 202, with the tilting shaft 82 rotatably engaged with the tilting shaft hole 202. Specifically, there are two receiving shaft holes 203, which are arranged opposite each other. The ends of the receiving shaft 83 are respectively received in the two receiving shaft holes 203 and rotatably engaged, allowing the tilting bracket 20 to be rotated relative to the receiving shaft 83 about the third axis 93 and accommodated. One end of the tilting shaft 82 is fixed to the steering bracket 12, and the other end extends into the tilting shaft hole 202 for rotatable engagement.

[0092] Furthermore, referring to Figure 17 , a third bearing 33 is disposed within the tilting shaft hole 202. The outer ring of the third bearing 33 is fixed to the inner wall of the tilting shaft hole 202, while the inner ring of the third bearing 33 is fixed to the tilting shaft 82. Specifically, the outer circumferential surface of the outer ring of the third bearing 33 abuts and is relatively fixed to the inner wall of the tilting shaft hole 202, while the inner circumferential surface of the inner ring of the third bearing 33 abuts and is relatively fixed to the outer wall of the tilting shaft 82. Due to the rollers disposed between the outer and inner rings, the outer and inner rings of the third bearing 33 can rotate relative to each other in the circumferential direction while being relatively fixed in the axial direction. The provision of the third bearing 33 reduces friction between the storage shaft 83 and the tilting shaft 82, facilitating tilting of the fuselage 10. Furthermore, the third bearing 33 ensures that the storage shaft 83 and the tilting shaft 82 are relatively fixed in the direction of the second axis 92.

[0093] Optionally, as shown in Figure 18 , a fourth bearing 34 is disposed within the receiving shaft hole 203. The outer ring of the fourth bearing 34 is affixed to the inner wall of the receiving shaft hole 203, and the inner ring of the fourth bearing 34 is affixed to the outer circumferential surface of the receiving shaft 83. Specifically, there are two fourth bearings 34, one disposed within each of the two receiving shaft holes 203. In other embodiments, there can be only one fourth bearing 34, disposed within either receiving shaft hole 203. The provision of the fourth bearing 34 significantly reduces friction. Furthermore, the fourth bearing 34 can be used to secure the tilting bracket 20 and the receiving shaft 83 relative to each other on the third axis 93. In this embodiment, since the fourth bearing 34 must bear the weight of the fuselage 10 after the tilting bracket 20 is mounted on the fixture, a high axial load bearing capacity is required. Therefore, the fourth bearing 34 is preferably a thrust ball bearing or a thrust roller bearing, both of which have excellent axial load bearing capacity.

[0094] In another embodiment of the present disclosure, referring to FIG. 19 , the propeller 100 further includes an adapter 40 disposed between the lift shaft 82 and the storage shaft 83 . The adapter 40 is rotatably connected to the fuselage 10 via the lift shaft 82 , and is rotatably connected to the lift bracket 20 via the storage shaft 83 . It is understood that different carrier designs vary. There are cases where, after the lift bracket 20 is mounted to the carrier via a clamp, the distance between the fuselage 10 and the carrier is too small, limiting the lift angle of the fuselage 10 and preventing it from reaching the appropriate angle. To address this issue, the adapter 40 increases the distance between the fuselage 10 and the carrier, ensuring sufficient lift. Furthermore, due to differences in carrier design, there are cases where, after the lift bracket 20 is mounted to the carrier via a clamp, the fuselage 10 is too high or too low. If the fuselage 10 is too high, the propeller will not be able to fully contact the water, thus failing to generate stable propulsion. If the fuselage 10 is too low, it can easily collide with rocks in shallow waters, or the propeller can become entangled with foreign objects such as aquatic plants, causing accidents. Therefore, by providing an adapter 40, the adapter 40 can change the relative position of the lifting axis 82 and the storage axis 83, thereby changing the relative distance between the fuselage 10 and the carrier, allowing the propeller 100 to better adapt to different carriers.

[0095] In one embodiment of this embodiment, please continue to refer to Figure 19. The adapter 40 is fixed to the tilting shaft 82. The storage shaft 83 is fixedly set on the adapter 40, and the tilting bracket 20 is provided with a storage shaft hole 203. The storage shaft 83 rotates with the storage shaft hole 203. Specifically, the adapter 40 in this embodiment is rod-shaped and extends in a direction perpendicular to both the second axis 92 and the third axis 93. One end of the adapter 40 is fixedly connected to the tilting shaft 82, and the other end of the adapter 40 is fixedly connected to the top of the storage shaft 83. The bottom end of the adapter 40 passes through the storage shaft hole 203 and is provided with a threaded nut 61 to constrain the relative position of the tilting bracket 20 and the adapter 40 to prevent the tilting bracket 20 from separating from the adapter 40. The steering bracket 12 of the fuselage 10 is provided with a tilting shaft hole 202. The end of the tilting shaft 82 away from the adapter 40 extends into the tilting shaft hole 202 for rotational engagement. It is understandable that this embodiment utilizes the provision of the adapter 40 to increase the distance between the lifting bracket 20 and the carrier, which can ensure that the fuselage 10 is fully lifted.

[0096] In one embodiment, referring to Figure 20 , the difference from the previous embodiment lies in the method for restraining the tilting bracket 20 and the adapter 40. In this embodiment, a fifth bearing 35 is disposed within the receiving shaft hole 203. The outer ring of the fifth bearing 35 is secured by abutting against the inner wall of the receiving shaft hole 203, while the inner ring of the fifth bearing 35 is secured by abutting against the outer circumference of the receiving shaft 83. Rollers between the outer and inner rings secure the receiving shaft 83 and the tilting bracket 20 relative to each other along the third axis 93.

[0097] In one embodiment, referring to Figure 21 , the difference from the previous embodiment lies in the arrangement of the receiving shaft 83 and the receiving shaft hole 203. In this embodiment, the adapter 40 defines a receiving shaft hole 203. The receiving shaft 83 is fixedly mounted on the tilting bracket 20 and rotatably engages with the receiving shaft hole 203. Specifically, one end of the receiving shaft 83 is fixed to the tilting bracket 20, while the other end passes through the receiving shaft hole 203 and is threadedly engaged with the nut 61 to constrain the relative position of the tilting bracket 20 and the adapter 40, preventing separation of the tilting bracket 20 and the adapter 40.

[0098] In one embodiment, please refer to Figure 22. Compared with the previous embodiment, the difference lies in the method of constraining the tilting bracket 20 and the adapter 40. In this embodiment, a sixth bearing 36 is provided in the storage shaft hole 203, and the outer ring of the sixth bearing 36 is fitted and fixed to the inner wall of the storage shaft hole 203, and the inner ring of the sixth bearing 36 is fitted and fixed to the outer circumferential surface of the storage shaft 83. The rollers between the outer ring and the inner ring are used to relatively fix the storage shaft 83 and the tilting bracket 20 in the direction of the third axis 93.

[0099] In one embodiment, referring to FIG. 23 , the difference from the embodiment shown in FIG. 19 lies in the arrangement of the tilting shaft 82 and the tilting shaft hole 202. In this embodiment, the adapter 40 is rotatably connected to the tilting shaft 82. Specifically, the adapter 40 has a tilting shaft hole 202 defined at one end away from the receiving shaft 83. The tilting shaft 82 is disposed on the body 10 (the tilting shaft 82 may be fixed to the body 10, or may be slotted in the body 10 into which the tilting shaft 82 extends for rotational engagement. Preferably, the tilting shaft 82 is fixed to the body 10). The tilting shaft 82 extends into the tilting shaft hole 202 for rotational engagement.

[0100] In one embodiment, referring to FIG. 24 , the difference from the previous embodiment lies in the arrangement of the receiving shaft 83 and the receiving shaft hole 203. In this embodiment, the adapter 40 defines a receiving shaft hole 203, and the receiving shaft 83 is fixedly mounted on the tilting bracket 20 and rotatably engages with the receiving shaft hole 203. Specifically, one end of the receiving shaft 83 is fixed to the tilting bracket 20, while the other end passes through the receiving shaft hole 203 and is threadedly engaged with the nut 61 to constrain the relative position of the tilting bracket 20 and the adapter 40, thereby preventing the tilting bracket 20 and the adapter 40 from separating.

[0101] It is understood that in each of the embodiments shown in Figures 19 to 24, the third axis 93 of the storage shaft 83 is not aligned with and is perpendicular to the second axis 92 of the tilting shaft 82. In other embodiments, referring to Figure 25, the third axis 93 and the second axis 92 intersect and are perpendicular, and the adapter 40 extends along the direction of the third axis 93. The bottom end of the adapter 40 is fixed with the storage shaft 83, which rotatably engages with the storage shaft hole 203 on the tilting bracket 20. The top end of the adapter 40 is fixed with the tilting shaft 82, which rotatably engages with the tilting shaft hole 202 on the fuselage 10. This arrangement increases the height of the fuselage 10 relative to the carrier, thereby preventing the fuselage 10 from wading too deep into water and being interfered with by debris. Of course, in order to lower the height of the fuselage 10 relative to the vehicle so that the fuselage 10 can fully wade through water and provide stable propulsion, the adapter 40 can also be configured to have a lifting shaft 82 fixed at the bottom and a storage shaft 83 fixed at the top.

[0102] It can be understood that in each of the embodiments shown in Figures 23 to 25, a nut 61 is provided on the end of the storage shaft 83 away from the adapter 40 to constrain the relative positions of the tilting bracket 20 and the adapter 40.

[0103] In one embodiment of the present disclosure, as shown in Figures 26 and 27 , a tilting shaft 82 is provided between the body 10 and the tilting bracket 20. The body 10 is rotatably connected to the tilting bracket 20 via the tilting shaft 82, allowing the body 10 to rotate relative to the tilting bracket 20 about the axis of the tilting shaft 82. The body 10 can slide relative to the tilting bracket 20. After the tilting bracket 20 is released from the clamp, the tilting bracket 20 can slide relative to the body 10 until it folds with the body 10. Specifically, the sliding direction of the tilting bracket 20 relative to the body 10 is perpendicular to the second axis 92 of the tilting shaft 82. It will be understood that when in use, the body 10 can be tilted relative to the tilting bracket 20 using the tilting shaft 82. When not in use, after the tilting bracket 20 is removed from the clamp, the tilting bracket 20 can slide relative to the body 10 via the tilting shaft 82 for storage. The relative sliding of the tilting bracket 20 and the body 10 can be achieved by forming a sliding pair between the tilting shaft 82 and the tilting bracket 20, or by forming a sliding pair between the tilting shaft 82 and the body 10, or by providing a separate component between the tilting shaft 82 and the tilting bracket 20, forming a sliding pair between the component and the tilting bracket 20, and sliding the tilting bracket 20 relative to the component and the tilting shaft 82, or by providing a separate component between the tilting shaft 82 and the body 10, forming a sliding pair between the component and the body 10, and driving the tilting shaft 82 and the tilting bracket 20 to slide relative to the body 10. By storing the tilting bracket 20 in a sliding manner, the storage path of the tilting bracket 20 is short, the operation is simple, and the applicability is strong.

[0104] In one embodiment of this implementation mode, please continue to refer to Figures 26 and 27. The tilting bracket 20 is provided with a slide groove 205, and the end of the tilting shaft 82 is slidably engaged with the slide groove 205. Specifically, one end of the tilting shaft 82 is rotationally engaged with the tilting shaft hole 202 of the steering bracket 12, and the other end of the tilting shaft 82 extends into the slide groove 205 for sliding engagement. Preferably, when the tilting bracket 20 is installed on the fixture, the slide groove 205 extends in the horizontal direction and passes through the tilting bracket 20. By providing the slide groove 205 on the tilting bracket 20, the end of the tilting shaft 82 is slidably engaged with the slide groove 205. After the tilting bracket 20 is detached from the fixture, the tilting bracket 20 can slide relative to the tilting shaft 82 to be stored on one side of the fuselage 10.

[0105] To prevent the tilting of the body 10 from being affected by relative sliding between the tilting shaft 82 and the tilting bracket 20 during use, a limiting structure 60 is provided between the tilting shaft 82 and the tilting bracket 20. This limiting structure 60 is used to limit the relative position of the tilting shaft 82 and the tilting bracket 20 after the tilting shaft 82 slides relative to the tilting bracket 20 away from the clamp. In this embodiment, a protrusion 65 is provided on the inner wall of the slide 205 at the end away from the body 11. This protrusion 65 prevents the tilting shaft 82 from disengaging from the slide 205 from that side. A first limiting hole 206 and a second limiting hole 207 are provided on the inner wall of the end of the slide 205 near the body 11. During use, the first limiting hole 206 is positioned closer to the body 11 than the second limiting hole 207. The limiting structure 60 includes a fixing screw 63 and a movable pin 64. The fixing screw 63 is mounted and fixed to the tilting bracket 20 through the first limiting hole 206 and protrudes from the inner wall of the slide 205 to prevent the tilting shaft 82 from disengaging the slide 205 from the right side. The movable pin 64 is disposed in the second limiting hole 207. A spring is also disposed between the movable pin 64 and the tilting bracket 20. One end of the spring is fixed to the outer wall of the tilting bracket 20, and the other end is fixed to the top of the movable pin 64, facing the outer wall of the tilting bracket 20. The spring provides elastic force to the movable pin 64 along its axis. When in use, the bottom end of the movable pin 64 protrudes from the inner wall of the slide 205, confining the tilting shaft 82 between the movable pin 64 and the fixing screw 63, preventing the tilting shaft 82 from sliding relative to the tilting bracket 20 and affecting the tilting of the body 10. When not in use, the movable pin 64 can be pulled up so that the bottom end of the movable pin 64 no longer protrudes from the inner wall of the slide 205, and the tilting shaft 82 is no longer limited by the movable pin 64. The tilting bracket 20 can be stored by sliding relative to the tilting shaft 82. In addition, the provision of the spring can facilitate the resetting of the movable pin 64 to improve convenience. In this embodiment, a fixing screw 63 and a movable pin 64 are used to limit the tilting shaft 82 in the slide 205. In other embodiments, the positions of the protrusion 65 and the fixing screw 63 can also be swapped. The present disclosure does not limit the form of the limiting structure 60.

[0106] Further, referring to Figures 26 and 27 , the slide 205 restricts the tilting shaft 82 from rotating relative to the tilting bracket 20 about the second axis 92. Specifically, the end of the tilting shaft 82 includes two parallel mating surfaces 821, and the inner wall of the slide 205 includes two parallel guide surfaces 2051. The two mating surfaces 821 mate with corresponding guide surfaces 2051, and both the mating surfaces 821 and the guide surfaces 2051 are perpendicular to the tilting surface of the fuselage 10. It can be understood that the tilting surface is a plane perpendicular to the second axis 92 of the tilting shaft 82, and the fuselage 10 tilts by rotating on the tilting surface. The two mating surfaces 821 are located on opposite sides of the end of the tilting shaft 82, and the two guide surfaces 2051 are the inner walls of the slide 205 that face each other. Preferably, the slide 205 is a T-shaped slot, and the end of the tilting shaft 82 is T-shaped to facilitate the locking of the tilting shaft 82 into the slide 205. By setting two mating surfaces 821 and two sliding guide surfaces 2051, the rotation of the tilting shaft 82 relative to the tilting bracket 20 can be better limited, that is, there is only sliding freedom but no rotation freedom between the tilting shaft 82 and the tilting bracket 20, avoiding affecting the storage of the tilting bracket 20.

[0107] In another embodiment of this embodiment, please refer to Figure 28. Compared with the previous embodiment, the difference lies in the way the tilting bracket 20 is slidably connected to the tilting shaft 82. In this embodiment, the tilting shaft 82 is provided with a slide groove 205, and the tilting bracket 20 is provided with a guide rail 21 that slides with the slide groove 205. The slide groove 205 and the guide rail 21 both extend in a direction parallel to the tilting surface of the fuselage 10. Specifically, when in use, the slide groove 205 and the guide rail extend in the horizontal direction. Preferably, the cross-section of the guide rail is T-shaped, and the slide groove 205 is a T-shaped groove, so that the tilting bracket 20 can be easily connected to the slide groove 205.

[0108] Further, please continue to refer to Figures 29 to 32b. In order to prevent the relative sliding between the lifting shaft 82 and the lifting bracket 20 from affecting the lifting of the fuselage during use, a limiting hole is opened on the guide rail 21, and the lifting shaft 82 in use is constrained by fixing screws or movable pins.

[0109] Specifically, referring to Figures 29 and 30, the guide rail 21 is provided with two limiting holes (including a first limiting hole 206 and a second limiting hole 207). The limiting structure 60 includes two fixing screws (including a first fixing screw 63a and a second fixing screw 63b). The first fixing screw 63a extends into the first limiting hole 206 and protrudes from the surface of the guide rail 21, and the second fixing screw 63b extends into the second limiting hole 207 and protrudes from the surface of the guide rail 21, thereby constraining the tilting axis 82 between the first fixing screw 63a and the second fixing screw 63b. It is understood that after the tilting bracket 20 is mounted on the fixture, the body needs to be tilted. If the tilting axis 82 slides relative to the tilting bracket 20, the tilting process will not proceed normally. Therefore, the first fixing screw 63a and the second fixing screw 63b are required to prevent the tilting axis 82 from sliding relative to the tilting bracket to ensure normal tilting. In addition, after the tilting bracket 20 is removed from the clamp, when the tilting bracket 20 needs to be stored, the first fixing screw 63a can be removed from the first limiting hole 206 to restore the freedom of sliding of the tilting shaft 82 relative to the tilting bracket 20, thereby facilitating storage.

[0110] Alternatively, referring to Figures 31 to 32b, the end of the tilting shaft 82 defines a first mounting hole 208a and a second mounting hole 208b. The limiting structure 60 includes a first movable pin 64a and a second movable pin 64b. The first movable pin 64a is mounted and fixed in the first mounting hole 208a, and the second movable pin 64b is mounted and fixed in the second mounting hole 208b. When not in use, the first movable pin 64a and the second movable pin 64b are elastically supported against the guide rail 21 (see Figure 32a for details). The first movable pin 64a and the second movable pin 64b do not affect the sliding of the tilting shaft 82 relative to the tilting bracket. The guide rail 21 is provided with a first limiting hole 206 and a second limiting hole 207. When the tilting shaft 82 moves relative to the guide rail 21 via the slide slot 205 to the end of the guide rail 21 away from the clamp, one end of the first movable pin 64a extends into the first limiting hole 206, and one end of the second movable pin 64b extends into the second limiting hole 207, thereby relatively fixing the tilting shaft 82 and the tilting bracket 20 provided with the guide rail 21 (see FIG. 32b for details). In other embodiments, the number of movable pins 64 can also be one or more than two to form a constraint.

[0111] In another embodiment of this embodiment, please refer to Figures 33a and 33b. Compared with the previous embodiment (i.e., the embodiment provided in Figure 27), the difference lies in the different way of forming a rotation pair with the tilting shaft 82. In this embodiment, the tilting bracket 20 is provided with a slide 205, the tilting shaft 82 is fixed to the steering bracket 12, the end of the tilting shaft 82 is provided with a first matching structure, and the end of the slide 205 away from the clamp is provided with a second matching structure. When the end of the tilting shaft 82 slides to the end of the slide 205 away from the clamp, the first matching structure and the second matching structure cooperate to form a rotation pair. The fuselage 10 can be tilted relative to the tilting bracket 20 through this rotation pair.

[0112] Further, referring to Figures 33a and 33b, the first mating structure is a retractable pin 71 that is retractable along the second axis 92 of the tilting shaft 82, and the second mating structure is a pin hole 72. When the end of the tilting shaft 82 slides to the end of the slide 205 away from the clamp, the retractable pin 71 extends into the pin hole 72 to rotationally engage with the pin hole 72. Specifically, the end of the tilting shaft 82 defines a first fixing hole 822, into which the retractable pin 71 is fixedly mounted. When not in use, it elastically abuts against the inner wall of the slide 205 (see Figure 33a for details). When the tilting shaft 82 slides within the slide 205 to the end away from the clamp, the retractable pin 71 aligns with the pin hole 72 and, under elastic force, extends into the pin hole 72, thereby rotationally engaging with the pin hole 72 (see Figure 33b for details), forming a rotational pair between the tilting shaft 82 and the tilting bracket 20, allowing the fuselage 10 to be tilted. At the same time, the cooperation between the retractable pin 71 and the pin hole 72 can restrict the tilting shaft 82 from sliding further in the slide groove 205, thereby constraining the relative position of the tilting shaft 82 and the tilting bracket 20. In addition, when it is necessary to release the constraint between the tilting shaft 82 and the tilting bracket 20, a thrust can be applied to the retractable pin 71 on the side of the limit hole facing away from the tilting shaft 82, causing the retractable pin 71 to move away from the pin hole 72, and the tilting shaft 82 and the tilting bracket 20 can resume relative sliding freedom.

[0113] In another embodiment of this embodiment, please refer to Figures 34a and 34b. Compared with the previous embodiment, the difference lies in the form of the first matching structure and the second matching structure. In this embodiment, the first matching structure is constructed as a pin hole 72, and the second matching structure is constructed as a telescopic pin 71 that can be retracted along the second axis 92 of the tilting shaft 82. A second fixing hole 209 is provided on the tilting bracket 20, and the telescopic pin 71 is movably installed in the mounting hole 208. The telescopic pin 71 includes a pin head 711 and a pin rod 712. The pin rod 711 extends into the mounting hole 208 for movably connection. The pin head 711 is connected to one end of the pin rod 712 and is located on the outside of the tilting bracket 20 facing away from the tilting shaft 82. The radial dimension of the pin head 711 is larger than the radial dimension of the pin rod 712. A spring is further provided between the pin head 711 and the tilting bracket 20. One end of the spring is fixed to the surface of the tilting bracket 20 opposite to the pin head 711, and the other end of the spring is fixed to the surface of the tilting bracket 20 opposite to the pin head 711. Under normal circumstances, the pin rod 712 protrudes from the inner wall of the slide groove 205. When the tilting freedom is required, the tilting shaft 82 can slide along the slide groove 205 relative to the tilting bracket 20 to the vicinity of the pin rod 712, and then apply tension to the pin head 711 so that one end of the pin rod 712 no longer protrudes from the inner wall of the slide groove 205. The tilting shaft 82 can continue to slide and align the pin hole 72 with the pin rod 712. Thereafter, the application of tension to the pin head 711 is stopped. When the spring recovers its elastic deformation, the pin rod 712, driven by the spring, protrudes from the inner wall of the slide groove 205 again and extends into the pin hole 72 to rotate with the pin hole 72.

[0114] In yet another embodiment of this embodiment, please refer to FIG. 35 . Compared with the embodiment provided in FIG. 27 , the difference lies in the different method of forming a rotation pair with the tilting shaft 82. In this embodiment, the tilting bracket 20 is provided with a slide groove 205, and the propeller 100 further includes a slider 22. The slider 22 is slidably engaged with the slide groove 205, and the tilting shaft 82 is rotatably connected to the slider 22 to allow the tilting bracket 20 to rotate relative to the fuselage 10 about the second axis 92 of the tilting shaft 82. Specifically, the slider 22 is provided with a tilting shaft hole 202. One end of the tilting shaft 82 is fixed to the fuselage 10, and the other end is rotatably engaged with the tilting shaft hole 202. The tilting shaft 82 can rotate relative to the slider 22 about the second axis 92 of the tilting shaft 82.

[0115] The following is a detailed description of the detachable connection solution of the lifting bracket 20 and the clamp 200 of the propeller 100 provided in the present disclosure.

[0116] An embodiment of the present disclosure provides a propulsion device 1000, please refer to Figures 1a and 1b. The propulsion device 1000 includes a clamp 200 and a propeller 100 provided in an embodiment of the present disclosure. The lifting bracket 20 of the propeller 100 is detachably connected to the clamp 200, and the clamp 200 is used to be fixed to a carrier. Specifically, the propulsion device 1000 includes a fuselage 10, a clamp 200, and a lifting bracket 20. The clamp 200 is used to be fixed to a carrier, and the lifting bracket 20 is detachably connected to the clamp 200. The fuselage 10 is rotatably connected to the lifting bracket 20 so as to be lifted relative to the clamp 200 through the lifting bracket 20. After the lifting bracket 20 is detached from the clamp 200, the lifting bracket 20 can move relative to the fuselage 10 until it is folded with the fuselage 10.

[0117] By configuring the tilting bracket 20 to be movable relative to the body 10 and folded with the body 10 after being released from the clamp 200, the tilting bracket 20 is stowed, thereby reducing the space occupied by the entire propeller 100. Furthermore, the tilting bracket 20 and the clamp 200 are detachably connected, making it easy to assemble and disassemble the tilting bracket 20 before and after using the propeller 100, thereby improving convenience and enhancing the user experience.

[0118] Specifically, referring to FIG. 36 , and in conjunction with the propeller of the embodiment shown in FIG. , the tilting bracket 20 is provided with a first mounting portion 110, and the clamp 200 is provided with a second mounting portion 210. The first mounting portion 110 and the second mounting portion 210 are relatively fixed by the gravity of the tilting bracket 20 and the body 10. When an external force overcomes the gravity of the tilting bracket 20 and the body 10, the first mounting portion 110 and the second mounting portion 210 can separate, and the first mounting portion 110 can move relative to the body 10 until it folds with the body 10. It will be understood that under the action of the gravity of the tilting bracket 20 and the body 10, the first mounting portion 110 and the second mounting portion 210 are relatively fixed, that is, the tilting bracket 20 and the clamp 200 are relatively fixed. However, when the external force overcomes the gravity of the tilting bracket 20 and the body 10, the first mounting portion 110 and the second mounting portion 210 can separate, that is, the tilting bracket 20 and the clamp 200 are separated. By utilizing gravity to complete the installation of the lifting bracket 20 and the fuselage 10, and overcoming gravity to complete the disassembly of the lifting bracket 20 and the clamp 200, the installation steps are simple and quick, with good convenience, which is conducive to improving user experience.

[0119] In one embodiment, referring to Figures 36 to 38 , the tilting bracket 20 includes a first bracket 25 and a second bracket 26 , respectively disposed on opposite sides of the body 10 and rotatably connected to the body 10. The body 10 can tilt relative to the first bracket 25 and the second bracket 26 . Both the first bracket 25 and the second bracket 26 are provided with a first mounting portion 110 . Specifically, the first bracket 25 and the second bracket 26 are respectively disposed on either side of the steering bracket 12 and rotatably connected to the steering bracket 12 . Preferably, the first bracket 25 and the second bracket 26 are substantially mirror-symmetrical about a certain plane. The first bracket 25 and the second bracket 26 can rotate synchronously relative to the steering bracket 12 to tilt the body 11 or to retract the first bracket 25 and the second bracket 26 . The provision of the first bracket 25 and the second bracket 26 provides the tilting bracket 20 with greater structural strength, thereby enhancing the stability of the connection between the tilting bracket 20 and the fixture 200 .

[0120] Further, referring to Figures 36 to 38, one of the first bracket 25 and the fuselage 10 is provided with a first tilting axis 82a, and the other is provided with a first tilting axis hole 202a. One of the second bracket 26 and the fuselage 10 is provided with a second tilting axis 82b, and the other is provided with a second tilting axis hole 202b. The axis of the first tilting axis 82a and the axis of the second tilting axis 82b coincide with each other. The first tilting axis 82a and the first tilting axis hole 202a are rotationally engaged, and the second tilting axis 82b and the second tilting axis hole 202b are rotationally engaged to allow the fuselage 10 to tilt. In this embodiment, the first tilting axis 82a is fixed to the first bracket 25, and the second tilting axis 82b is fixed to the second bracket 26. The first tilting axis hole 202a and the second tilting axis hole 202b are both provided on the steering bracket 12, and the first tilting axis hole 202a and the second tilting axis hole 202b are connected. In other embodiments, the first tilting axis 82a may be fixed to the steering bracket 12, and the first tilting axis hole 202a may be defined in the first bracket 25; and / or the second tilting axis 82b may be fixed to the steering bracket 12, and the second tilting axis hole 202b may be defined in the second bracket 26. By providing the first tilting axis 82a and the second tilting axis 82b, the fuselage 10 may be tilted relative to the tilting bracket 20 via the first tilting axis 82a and the second tilting axis 82b. The first tilting axis 82a and the second tilting axis 82b may effectively support the fuselage 10 and enable the fuselage 10 to tilt.

[0121] Further, please refer to FIGS. 36 to 38. The warping bracket 20 includes a limiting rod 27. One end of the limiting rod 27 is connected to the first bracket 25, and the other end of the limiting rod 27 is connected to the second bracket 26 to limit the first warping shaft 82a from disengaging from the first warping shaft hole 202a and limit the second warping shaft 82b from disengaging from the second warping shaft hole 202b. Specifically, the extending direction of the limiting rod 27 is parallel to the axes of the first warping shaft 82a and the second warping shaft 82b. The limiting rod 27 can be fixed to one of the first bracket 25 and the second bracket 26 by means of threaded connection and connected to the other by means of inserting holes, that is, the limiting rod 27 only needs to ensure that the first bracket 25 and the second bracket 26 can rotate relative to the fuselage 10 synchronously. Of course, one end of the limiting rod 27 can also be fixed to the first bracket 25 and the other end can be fixed to the second bracket 26. The present disclosure does not limit the connection manner between the limiting rod 27 and the first bracket 25 and the second bracket 26.

[0122] Further, please refer to FIGS. 36 to 38. The second mounting portion 210 is provided with a card slot 2101, and the card slot 2101 extends from the top end to the bottom end of the fixture 200. The first mounting portion 110 is provided with a card block 1101, and the card block 1101 extends into the card slot 2101 from the top side of the card slot 2101. Under the gravity of the warping bracket 20 and the fuselage 10, the card block 1101 is fixed in the card slot 2101. In this embodiment, the cross section of the card block 1101 is square, and the card slot 2101 is a square slot capable of accommodating the entire card block 1101 or a "匚"-shaped slot for accommodating a part of the card block 1101. Preferably, the card slot 2101 extends in the vertical direction, and the card block 1101 can extend into the card slot 2101 in the vertical direction and be fixed in the card slot 2101 under the gravity of the warping bracket 20 and the fuselage 10, so as to realize the relative fixation of the warping bracket 20 and the fixture 200. It can be understood that the relative fixation of the warping bracket 20 and the fixture 200 is realized by the cooperation of the card block 1101 and the card slot 2101 and the gravity of the warping bracket 20 and the fuselage 10, and the structure and the installation method are relatively simple.

[0123] Further, referring to Figures 36 to 38 , there are two slots 2101, one located inside the carrier and the other outside the carrier. There are also two clamping blocks 1101, each inserted from the top of the clamp 200 into the two slots 2101. It will be appreciated that by providing two slots 2101, one located inside the carrier and one located outside the carrier, the weight of the body 10 and the lifting bracket 20 can be better transferred to the carrier through the clamp 200, resulting in a more even load distribution on the clamp 200 and making it less susceptible to damage. Of the two blocks 1101, the length of the block 1101 located inside the carrier is shorter than the length of the block 1101 located outside the carrier. It can be understood that the main force point of the block 1101 located inside the carrier is the top end, so the block 1101 inside the carrier does not need to be designed to be too long for structural strength, while the main force point of the block 1101 outside the carrier is the bottom end. In order to ensure sufficient structural strength, it needs to be designed to be relatively longer. Through this design, the space occupied by the lift bracket 20 can be reduced, which is conducive to storage.

[0124] Specifically, referring to Figures 36 to 38 , the clamp 200 includes a first mounting plate 231, a second mounting plate 232, and a crossbeam 233. One end of the crossbeam 233 is connected to the top of the first mounting plate 231, and the other end of the crossbeam is connected to the top of the second mounting plate 232. The first mounting plate 231 and / or the second mounting plate 232 are used to clamp to the carrier. The first mounting plate 231 is located inside the carrier, while the second mounting plate 232 is located outside the carrier. In use, the side of the second mounting plate 232 facing away from the first mounting plate 231 abuts against the fuselage 10, providing horizontal support for the fuselage 10. When the tilting bracket 20 includes a first bracket 25 and a second bracket 26, there are two first mounting plates 231 and two crossbeams 233. The two first mounting plates 231 are each secured to the second mounting plate 232 via a corresponding crossbeam 233, corresponding to the first bracket 25 and the second bracket 26, respectively. There are four slots 2101, all extending vertically. Two slots 2101 are located on the two crossbeams 233, and the other two slots 2101 are located on the second mounting plate 232. There are four blocks 1101, two of which are located on the first bracket 25, and the other two on the second bracket 26. Both the first bracket 25 and the second bracket 26 include a connecting rod 120, with the two blocks 1101 connected at their respective ends. A first tilting axis 82a is located at the end of the connecting rod 120 of the first bracket 25 that is away from the clamp 200, facing away from the block 1101. A second tilting axis 82b is located at the end of the connecting rod 120 of the second bracket 26 that is away from the clamp 200, facing away from the block 1101. The combination of multiple blocks 1101 and multiple slots 2101 significantly improves the connection strength between the tilting bracket 20 and the clamp 200. In addition, the connecting rod 120 includes two bent parts, so that when installed on the clamp 200, there is a gap between the middle part of the connecting rod 120 and the crossbeam 233 (see Figure 2), which can prevent the connecting rod 120 from colliding with the clamp 200 and generating noise. The clamp 200 also includes two chucks 220, which are respectively arranged on the two first mounting plates 231. The chucks 220 are used to cooperate with the second mounting plate 232 to tighten and fix the clamp 200 on the carrier after the clamp 200 is placed on the carrier. In other embodiments, the chucks 220 can also be arranged on the second mounting plate 232. This disclosure does not limit the form of the chucks 220.

[0125] In one embodiment, referring to FIG. 39 , the difference from the previous embodiment lies in the specific arrangement of the block 1101 and the slot 2101. In this embodiment, the first mounting portion 110 is provided with a slot 2101, and the second mounting portion 210 is provided with a block 1101. The block 1101 extends from the top to the bottom of the clamp 200. The first mounting portion 110 is inserted into the block 1101 from the top side through the slot 2101. Under the gravity of the tilting bracket 20 and the body 10, the block 1101 is fixed to the slot 2101. Specifically, there are four blocks 1101 in this embodiment, two of which are constructed as part of the first mounting plate 231, and the other two blocks 1101 are constructed on the second mounting plate 232. That is, two blocks 1101 are located inside the carrier, and two blocks 1101 are located outside the carrier. There are four card slots 2101, two of which are provided on the first bracket 25, and the other two card slots 2101 are provided on the second bracket 26. Preferably, the card block 1101 extends in the vertical direction after the clamp 200 is mounted on the carrier. It is understood that the relative fixation of the tilting bracket 20 and the clamp 200 is achieved by utilizing the cooperation between the card block 1101 and the card slot 2101 and the gravity of the tilting bracket 20 and the fuselage 10, and the structure and installation method are relatively simple. In addition, the card block 1101 and the card slot 2101 cooperate simultaneously inside and outside the carrier, and the load distribution on the clamp 200 is relatively uniform, making the clamp 200 less susceptible to damage.

[0126] It is understood that the tilting bracket 20 in the embodiments corresponding to Figures 36 and 39 includes a first bracket 25 and a second bracket 26, and both the first bracket 25 and the second bracket 26 are provided with a block 1101 or a slot 2101. In other embodiments, the block 1101 or the slot 2101 may be provided on only one of the first bracket 25 and the second bracket 26. The block 1101 or the slot 2101 may also have other structures different from those in the embodiments corresponding to Figures 36 and 39.

[0127] 36 and 39 , the tilting bracket 20 is retracted via the tilting shaft 82. In other embodiments, the tilting bracket 20 and the body 10 may be retracted by sliding relative to each other, or the tilting bracket 20 may be retracted by rotating relative to the body 10 via the retraction shaft 83, which will not be described in detail here.

[0128] In one embodiment, referring to FIG. 40 , the embodiment corresponding to FIG. 36 differs in the specific arrangement of the slot 2101 and the block 1101. In this embodiment, the second mounting portion 210 defines a slot 2101 that extends from the side of the fixture 200 facing the body 10 to the side away from the body 10. The first mounting portion 110 defines a block 1101 that extends into the slot 2101 from the side facing the body 10. Under the weight of the lifting bracket 20 and the body 10, the block 1101 forms friction with the inner wall of the slot 2101, securing the block 1101 relative to the body 10. Specifically, after the fixture 200 is secured to the carrier, the slot 2101 extends horizontally, allowing the block 1101 to be inserted horizontally into the slot 2101. It is understood that when in use, the tilting bracket 20 and the body 10 exert a significant gravity, generating pressure between the block 1101 and the inner wall of the slot 2101, thereby forming friction. This friction is used to prevent the block 1101 from leaving the slot 2101, thereby achieving relative fixation between the clamp 200 and the tilting bracket 20. Furthermore, when not in use, as long as the gravity of the tilting bracket 20 and the body 10 is overcome, the friction of the block 1101 disappears, allowing it to be separated from the clamp 200. By utilizing gravity to complete the installation of the tilting bracket 20 and the body 10, and overcoming gravity to complete the removal of the tilting bracket 20 and the clamp 200, the installation process is simple and quick, with great convenience, which is conducive to improving the user experience.

[0129] Further, referring to Figure 40 , the end of the clamping block 1101 away from the clamp 200 is rotatably connected to the body 10, allowing the clamping block 1101 to rotate relative to the body 10 until it folds with the body 10. Specifically, a tilting axis 82 is provided between the body 10 and the clamping block 1101, and the body 10 is tilted relative to the clamping block 1101 about the axis of the tilting axis 82 via the tilting axis 82. A storage shaft 83 is provided between the tilting axis 82 and the clamping block 1101, and the clamping block 1101 is rotated relative to the clamping block 1101 about the third axis 93 of the storage shaft 83 until it folds with the body 10. The third axis 93 is perpendicular to the second axis 92 of the tilting axis 82. Specifically, there are two clamping blocks 1101, extending in the same direction. One clamping block 1101 is fixed to one end of the storage shaft 83, and the other clamping block 1101 is fixed to the other end of the storage shaft 83. The storage shaft 83 and the two clamping blocks 1101 are an integrated structure, and the storage shaft 83 and the two clamping blocks 1101 can move synchronously. The end of the lifting shaft 82 is plate-shaped and has a storage shaft hole 203. The portion between the two ends of the storage shaft 83 rotates in the storage shaft hole 203, so that the lifting shaft 82 is confined between the two clamping blocks 1101. The tilting bracket 20 includes a first bracket 25 and a second bracket 26. The first bracket 25 and the second bracket 26 have identical structures, and each has two storage shafts 83 and two tilting shafts 82. Each bracket includes two latches 1101, each rotatably connected to the corresponding storage shaft 83 for storage. The tilting shaft 82 also allows the body 10 to be tilted. When the first bracket 25 and the second bracket 26 are mounted on the fixture 200, they are fixed relative to the fixture 200 and locked relative to each other. Neither the first bracket 25 nor the second bracket 26 can rotate relative to the tilting shaft 82 for storage using the degrees of freedom provided by the corresponding storage shafts 83. However, the degrees of freedom provided by the tilting shafts 82 are not constrained, and the body 11 can still be tilted.

[0130] Specifically, the slot 2101 is provided on the second mounting plate 232 of the fixture 200 and is a square hole extending through the second mounting plate 232. The number of slots 2101 corresponds to the number of blocks 1101, both being four, and all four slots 2101 extend horizontally. It will be appreciated that in the embodiment corresponding to FIG40 , the tilting bracket 20 is accommodated via the accommodation shaft 83. In other embodiments, the tilting bracket 20 and the body 10 may be accommodated by relative sliding, or the tilting bracket 20 may be accommodated by relative rotation with the body 10 via the tilting shaft 82. These will not be discussed further here.

[0131] The embodiment of the present disclosure also provides a movable device 2000 for use in water areas. Please refer to FIG41 . The movable device 2000 for use in water areas includes a carrier 300 and a propulsion device 1000. The clamp 200 of the propulsion device 1000 is fixed to the carrier 300. The movable device 2000 for use in water areas can be a water-based device such as a boat, a kayak, or a bamboo raft, which is not specifically limited. Specifically, the movable device 2000 for use in water areas also includes a tiller 400. The tiller 400 is mounted on the fuselage 10 and is used to control the tilting of the fuselage 10 and the orientation of the fuselage 10, thereby changing the course. By setting the tilting bracket 20 in the propeller 100 of the movable device 2000 so that it can move relative to the fuselage 10 to be folded with the fuselage 10 after being separated from the clamp 200, the storage of the tilting bracket 20 is completed, thereby reducing the space occupied by the entire propeller 100. At the same time, the lifting bracket 20 and the clamp 200 are detachably connected to facilitate assembly and disassembly between the lifting bracket 20 and the clamp 200 before and after the propeller 100 is used, thereby improving convenience and enhancing user experience.
