[0059] Referring to Figures 1 to 3 and Figure 37, an embodiment of the present application provides a propeller connection device 100. The propeller connection device 100 includes a first connection component 10 for connecting to a water body carrier 1001, a second connection component 20 for connecting to a propulsion power unit 200, and a limiting mechanism 30 configured on the first connection component 10 or the second connection component 20. The first connection component 10 and the second connection component 20 are detachably plugged in. The limiting mechanism 30 is provided with a locking component 31 and an unlocking component 32. The locking component 31 is used to lock the plugging of the first connection component 10 and the second connection component 20. The unlocking component 32 has an unlocking holding state for keeping the locking component 31 in an unlocked state, and the unlocking state is a state in which the locking component 31 is unlocked. When the unlocking component 32 is in the unlocking holding state, the second connection component 20 can receive a disassembly force and be disassembled relative to the first connection component 10.

[0060] In the thruster connection device 100 of the embodiment of the present application, when the first connection component 10 and the second connection component 20 are plugged in, the locking component 31 of the limiting mechanism 30 is used to lock the plugging of the first connection component 10 and the second connection component 20. When the first connection component 10 and the second connection component 20 are disassembled, the locking component 31 is unlocked, and the unlocking component 32 of the limiting mechanism 30 is in the unlocked holding state, so that the locking component 31 remains in the unlocked state. When the unlocking component 32 is in the unlocked holding state, the second connection component 20 can receive the disassembly force and be disassembled relative to the first connection component 10. In this way, the thruster connection device 100 can be disassembled conveniently and quickly, and at the same time, the thruster connection device 100 remains stable and does not shake after installation. In addition, the thruster 300 can be smaller and more compact when stored, and takes up less space. It is understood that by manipulating the unlocking assembly 32 to the unlocked hold state, the locking assembly 31 can be maintained in the unlocked state, thereby freeing both hands to disassemble the propulsion power unit 200, without having to use one hand to apply the unlocking force while the other hand applies the disassembly force. Because the propeller connecting device 100 is connected to the propulsion power unit 200, the propulsion power unit 200 is heavy and is generally not easy to disassemble with one hand. However, applying force to the propulsion power unit 200 with both hands can improve disassembly efficiency and facilitate quick disassembly.

[0061] Specifically, the first connecting component 10 can be a lifting fixture, and the water area carrier 1001 can be a hull. The first connecting component 10 is connected to the water area carrier 1001, for example, connected to the tail of the hull. The second connecting component 20 can be a steering bracket, and the second connecting component 20 is connected to the propulsion power unit 200. The first connecting component 10 and the second connecting component 20 are detachably plugged in. The limiting mechanism 30 can be configured on the first connecting component 10, or on the second connecting component 20 (as shown in Figure 2). The limiting mechanism 30 includes a locking component 31 (as shown in Figure 24) and an unlocking component 32 (as shown in Figure 23). When the first connecting component 10 is plugged in with the second connecting component 20, the water area carrier 1001 is connected to the propulsion power unit 200, and the propeller 300 can achieve lifting or steering of the water area carrier 1001. The locking assembly 31 can lock the connection between the first connecting assembly 10 and the second connecting assembly 20, preventing the first connecting assembly 10 and the second connecting assembly 20 from causing the water body 1001 and the propulsion power unit 200 to fail due to accidental separation. When the first connecting assembly 10 and the second connecting assembly 20 are disassembled, the locking assembly 31 enters an unlocked state, releasing the lock between the first connecting assembly 10 and the second connecting assembly 20. The unlocking assembly 32 can enter an unlocked hold state, maintaining the locking assembly 31 in the unlocked state. At this point, the user can apply a disassembly force, and the second connecting assembly 20 receives the disassembly force and can be disassembled relative to the first connecting assembly 10.

[0062] It should be noted that the first connecting assembly 10 and the second connecting assembly 20 are tolerance-matched. This tolerance fit makes the connection between the first connecting assembly 10 and the second connecting assembly 20 easier and prevents the second connecting assembly 20 and its connected propulsion power unit 200 from significantly shaking relative to the first connecting assembly 10. When removing the second connecting assembly 20 from the first connecting assembly 10, due to the very close tolerance between the first connecting assembly 10 and the second connecting assembly 20, a force to disengage from the first connecting assembly 10 (such as the upward force in Figures 1 and 2) must be applied simultaneously on both sides of the second connecting assembly 20 to prevent the second connecting assembly 20 from becoming stuck on the first connecting assembly 10. The user needs to use both hands to apply the disassembly force to the second connecting assembly 20 simultaneously. The locking assembly 31 also requires manual operation by the user to enter the unlocked state. In current technology, the locking assembly 31 requires manual control by the user to maintain the unlocked state. The user cannot simultaneously apply the disassembly force to the second connecting assembly 20 with both hands while keeping the locking assembly 31 unlocked. In the thruster connection device 100 of the present embodiment, the user controls the locking assembly 31 to enter the unlocked state, and the unlocking assembly 32 maintains the locking assembly 31 in the unlocked state, thereby allowing both hands to apply the disassembly force to the second connection assembly 20. A single user can complete the disassembly of the first connection assembly 10 and the second connection assembly 20 without continuously applying the unlocking force to the locking assembly 31. This makes disassembly of the first and second connection assemblies 20 more convenient.

[0063] 2 and 3 , in some embodiments, the first connecting component 10 is provided with one of the shaft sleeve 40 and the inserted shaft 50 , and the second connecting component 20 is provided with the other of the shaft sleeve 40 and the inserted shaft 50 .

[0064] Specifically, the first connecting assembly 10 can be provided with a shaft sleeve 40, and correspondingly, the second connecting assembly 20 can be provided with an insert shaft 50. Alternatively, the first connecting assembly 10 can be provided with an insert shaft 50, and correspondingly, the second connecting assembly 20 can be provided with a shaft sleeve 40 (as shown in FIG. 2 ). The first connecting assembly 10 and the second connecting assembly 20 are connected by plugging the insert shaft 50 into the shaft sleeve 40.

[0065] In some embodiments, the second connecting component 20 is rotatable relative to the first connecting component 10 via the insertion shaft 50 .

[0066] Specifically, if the first connecting component 10 is provided with an insert shaft 50 and the second connecting component 20 is provided with a sleeve 40, the insert shaft 50 of the first connecting component 10 is inserted into the sleeve 40 of the second connecting component 20. If the first connecting component 10 is provided with a sleeve 40 and the second connecting component 20 is provided with an insert shaft 50, the insert shaft 50 of the second connecting component 20 is inserted into the sleeve 40 of the first connecting component 10. The insert shaft 50 has the function of a tilting shaft (as shown in Figures 4 and 6) or a steering shaft (as shown in Figures 8 and 10). When a rotational force is applied to the second connecting component 20, the second connecting component 20 rotates around the axis of the insert shaft 50 to achieve steering or tilting of the propeller 300. In this way, the propulsion power device 200 connected to the second connecting component 20 can be turned or tilted relative to the water carrier 1001 connected to the first connecting component 10.

[0067] 4 to 7 , in some embodiments, the rotation direction of the second connecting component 20 relative to the first connecting component 10 via the insertion shaft 50 is the tilting direction of the propeller 300 , and the first connecting component 10 or the second connecting component 20 is further provided with a steering shaft 91 .

[0068] Specifically, as shown in Figures 4 and 5, Figure 5 is a disassembly diagram of Figure 4, and the plug shaft 50 is horizontally arranged in the view. The second connecting component 20 rotates relative to the first connecting component 10 via the plug shaft 50, and then can drive the propulsion power unit 200 connected to the second connecting component 20 to tilt. The rotation of the propulsion power unit 200 around the axis of the plug shaft 50 is the tilting of the propeller 300, that is, the rotation of the second connecting component 20 relative to the first connecting component 10 via the plug shaft 50 can cause the propeller 300 to tilt, for example, tilt upward or downward relative to the water surface. It can be understood that the role of tilting is: the angle between the propulsion power unit 200 and the water surface, as well as the height of the propulsion power unit 200 from the water surface can be controlled during the sailing process, so as to adapt to different water conditions, and when the boat is moored for too long and not used, the underwater part of the outboard motor can be tilted out of the water to avoid corrosion and collision of the underwater part. At this time, the first connecting assembly 10 is further provided with a steering shaft 91 (as shown in FIG. 4 ). For example, the steering shaft 91 is provided at the connection between the first connecting assembly 10 and the water body 1001. The first connecting assembly 10 includes a clamping member 12 and a steering connector 13. The clamping member 12 is mounted and fixed to the water body 1001. The steering connector 13 is rotatably connected to the clamping member 12 via the steering shaft 91. The steering connector 13 is also detachably connected to the second connecting assembly 20 via the plug shaft 50, and can be tilted and rotated relative to the second connecting assembly 20 via the plug shaft 50.

[0069] In another similar embodiment, an alternative to Figure 4 is provided, as shown in Figures 6 and 7. Figure 7 is a disassembly diagram of Figure 6. The second connecting assembly 20 is further provided with a steering shaft 91 (as shown in Figure 6). For example, a steering shaft 91 is provided at the connection between the second connecting assembly 20 and the propulsion power unit 200. The second connecting assembly 20 includes a second base 21 and a steering connector 13. The steering connector 13 is fixedly connected to the propulsion power unit 200. The second base 21 is rotatably connected to the steering connector 13 via the steering shaft 91 to enable the propulsion power unit 200 to be steerable. The second base 21 is also detachably connected to the first connecting assembly 10 via the plug shaft 50, and can also be tilted and rotated relative to the first connecting assembly 10 via the plug shaft 50.

[0070] In the embodiments of Figures 4 to 7, the steering shaft 91 is used to steer the propeller 300 left and right to adjust its course. Thus, the insertion shaft 50 and the steering shaft 91 can be used together to achieve the lifting and steering of the propeller 300, and thus the lifting and steering of the mobile device 1000 in the water area.

[0071] 8 to 11 , in some embodiments, the rotation direction of the second connecting component 20 relative to the first connecting component 10 via the insertion shaft 50 is the steering direction of the propeller 300 , and the first connecting component 10 or the second connecting component 20 is further provided with a tilting shaft 92 .

[0072] Specifically, referring to Figures 2, 8 and 9, Figure 9 is a disassembly diagram of Figure 8, in which the plug-in shaft 50 is arranged vertically in the view, and the second connecting component 20 rotates relative to the first connecting component 10 via the plug-in shaft 50, thereby realizing the steering of the propulsion power device 200 connected to the second connecting component 20. The rotation of the propulsion power device 200 around the axis of the plug-in shaft 50 is the steering of the propeller 300, that is, the rotation of the second connecting component 20 relative to the first connecting component 10 via the plug-in shaft 50 can cause the propeller 300 to steer, for example, to the left or to the right, to adjust the heading. At this time, the first connecting component 10 is also provided with a tilting shaft 92 (as shown in Figure 8), for example, a tilting shaft 92 is provided at the connection between the first connecting component 10 and the water carrier 1001. The first connecting assembly 10 includes a clamping member 12 and a first base 11. The clamping member 12 is used to clamp and securely mount on the water body 1001. The first base 11 is rotatably connected to the clamping member 12 via the tilting shaft 92 to drive the propulsion power unit 200 to tilt relative to the water body 1001. The first base 11 is also detachably connected to the second connecting assembly 20 via the insertion shaft 50, and the second connecting assembly 20 can be rotated relative to the first base 11 via the insertion shaft 50.

[0073] In an alternative embodiment to the embodiment of Figure 8 , as shown in Figures 10 and 11 (Figure 11 is a schematic diagram of the disassembly of Figure 10 ), the second connecting assembly 20 is further provided with a tilting shaft 92. For example, the tilting shaft 92 is provided at the connection between the second connecting assembly 20 and the propulsion power unit 200. The tilting shaft 92 is used to tilt the propeller 300 up and down. In this way, the insertion shaft 50 and the tilting shaft 92 can jointly achieve the tilting and steering of the propeller 300, and thus the tilting and steering of the mobile device 1000 in the water area.

[0074] The second connecting assembly 10 includes a second base 21 and a steering connector 13. The steering connector 13 is fixedly connected to the propulsion unit 200 and is rotatably connected to the second base 21 via a tilting shaft 92 to drive the propulsion unit 200 to tilt relative to the water body 1001. The second base 21 is also detachably connected to the first connecting assembly 10 via an insertion shaft 50, and the second base 21 can drive the propulsion unit 200 to steer relative to the first connecting assembly 10 via the insertion shaft 50.

[0075] Referring to Figure 2 , in certain embodiments, the first connection assembly 10 includes a first base 11 connected to the water body 1001, and the second connection assembly includes a second base 21 connected to the propulsion unit 200. The insertion shaft 50 is fixed to one of the first base 11 and the second base 21 and rotatably engages with the other of the first base 11 and the second base 21.

[0076] Specifically, the insertion shaft 50 can be fixed to the first base 11 of the first connecting component 10 and rotatably engaged with the second base 21 of the second connecting component 20. The insertion shaft 50 can also be fixed to the second base 21 of the second connecting component 20 and rotatably engaged with the first base 11 of the first connecting component 10.

[0077] Please refer to Figures 8 and 12. In some embodiments, the insertion shaft 50 is fixed to one of the first base 11 and the second base 21, and the sleeve 40 is fixed to the other of the first base 11 and the second base 21. The insertion shaft 50 and the sleeve 40 can be rotatably matched after being plugged in.

[0078] Specifically, if the plug shaft 50 is fixed to the first base 11 of the first connecting component 10, then the sleeve 40 is fixed to the second base 21 of the second connecting component 20 (as shown in Figure 8). The plug shaft 50 and the sleeve 40 are rotatably engaged after being plugged in. When the plug shaft 50 rotates, since the plug shaft 50 is fixedly connected to the first base 11, and the first base 11 can be connected to the water body 1001 via the clamping member 12, the sleeve 40 and the second base 21 fixedly connected to the sleeve 40 rotate relative to the plug shaft 50, with the first base 11 as a fixed position reference, thereby enabling the second connecting component 20 to rotate relative to the first connecting component 10 via the plug shaft 50.

[0079] Based on Figure 8 , an alternative embodiment is provided, as shown in Figures 12 and 13 . Figure 13 is a schematic diagram of the disassembly of Figure 12 . If the plug shaft 50 is fixed to the second base 21 of the second connecting assembly 20, then the sleeve 40 is fixed to the first base 11 of the first connecting assembly 10. The plug shaft 50 and sleeve 40 can rotate after being plugged in. Rotation of the plug shaft 50 causes the plug shaft 50 and the second base 21 to which it is fixed to rotate, allowing the second connecting assembly 20 to rotate relative to the first connecting assembly 10 via the plug shaft 50.

[0080] Please refer to Figures 14 to 17. In some embodiments, the insertion shaft 50 is fixed to one of the first base 11 and the second base 21, and the sleeve 40 is rotatably connected to the other of the first base 11 and the second base 21. The insertion shaft 50 and the sleeve 40 are relatively fixed after being plugged in.

[0081] Specifically, an embodiment is provided, as shown in Figures 14 and 15. Figure 15 is a schematic diagram of the disassembly of Figure 14. The plug shaft 50 is fixed to the first base 11 of the first connecting component 10, and the sleeve 40 is rotatably connected to the second base 21 of the second connecting component 20. The plug shaft 50 and the sleeve 40 are relatively fixed after being plugged in. When the plug shaft 50 rotates, since the plug shaft 50 is fixedly connected to the first base 11, and the first base 11 is connected to the water area carrier 1001, with the first base 11 as a fixed position reference, the second base 21 rotates relative to the sleeve 40 and the plug shaft 50, thereby realizing the rotation of the second connecting component 20 relative to the first connecting component 10 via the plug shaft 50.

[0082] An alternative embodiment based on the embodiment of FIG. 14 is provided, as shown in FIG. 16 and FIG. 17 . FIG. 17 is a schematic diagram of the disassembly of FIG. 16 . The insertion shaft 50 is fixed to the second base 21 of the second connecting assembly 20, and the sleeve 40 is rotatably connected to the first base 11 of the first connecting assembly 10. The insertion shaft 50 and the sleeve 40 are relatively fixed after insertion. Rotation of the insertion shaft 50 causes the insertion shaft 50, the sleeve 40, and the second base 21 fixedly connected to the insertion shaft 50 to rotate, thereby enabling the second connecting assembly 20 to rotate relative to the first connecting assembly 10 via the insertion shaft 50.

[0083] Referring also to Figure 2 , in certain embodiments, the first connecting assembly 10 includes a first base 11 connected to the water body 1001, and the second connecting assembly 20 includes a second base 21 connected to the propulsion unit 200. The plug-in shaft 50 is rotatably connected to one of the first base 11 and the second base 21, and the sleeve 40 is fixed to the other of the first base 11 and the second base 21. Once plugged in, the plug-in shaft 50 and sleeve 40 are relatively fixed.

[0084] In one embodiment, as shown in Figures 18 and 19 (Figure 19 is a schematic diagram of the disassembly of Figure 18), the insertion shaft 50 is rotatably connected to the first base 11 of the first connecting assembly 10, and the sleeve 40 is fixed to the second base 21 of the second connecting assembly 20. After insertion, the insertion shaft 50 and sleeve 40 are relatively fixed. When the insertion shaft 50 is rotated, the insertion shaft 50, sleeve 40, and the second base 21 fixedly connected to the sleeve 40 rotate, allowing the second connecting assembly 20 to rotate relative to the first connecting assembly 10 via the insertion shaft 50.

[0085] In another embodiment, as an alternative to the embodiment of Figure 18, as shown in Figures 20 and 21, Figure 21 is a disassembly diagram of Figure 20, the plug-in shaft 50 is rotatably connected to the second base 21 of the second connecting component 20, and the sleeve 40 is fixed on the first base 11 of the first connecting component 10. The plug-in shaft 50 and the sleeve 40 are relatively fixed after being plugged in. When the plug-in shaft 50 rotates, since the plug-in shaft 50 and the sleeve 40 are relatively fixed after being plugged in, the sleeve 40 is fixedly connected to the first base 11, and the first base 11 is connected to the water area carrier 1001, with the first base 11 as a fixed position reference, the second base 21 rotates relative to the plug-in shaft 50, thereby realizing the rotation of the second connecting component 20 relative to the first connecting component 10 via the plug-in shaft 50.

[0086] Please refer to Figure 2. In some embodiments, the plug shaft 50 is rotatably disposed on the first connecting component 10 or the second connecting component 20. The first connecting component 10 or the second connecting component 20 is provided with a limit member 60 for limiting the axial displacement of the plug shaft 50 relative to the first base 11 or the second base 21 along the plug shaft 50.

[0087] Specifically, please refer to Figures 2 and 18 together. Figure 2 is a partial cross-sectional schematic diagram of the embodiment of Figure 18. The limiting member 60 can be an annular structure, such as a steel ring or other metal material that can limit the structure. The plug-in shaft 50 is rotatably arranged on the first base 11 of the first connecting component 10, and the limiting member 60 is correspondingly arranged on the first connecting component 10 (as shown in Figures 2 and 18). At this time, the limiting member 60 is used to limit the plug-in shaft 50 to the first base 11, so that the plug-in shaft 50 will not be displaced axially along the plug-in shaft 50 relative to the first base 11. In one example, the plug-in shaft 50 is provided with a limiting groove 61 along the circumference, and a limiting step 62 is provided at a corresponding position on the inner side wall of the first base 11. The inner side wall of the limiting member 60 is accommodated in the limiting groove 61, and the outer side wall of the limiting member 60 is abutted against the limiting step 62 of the first base 11. In FIG. 2 , the insertion shaft 50 is further provided with a limiting flange 63 separated from the limiting member 60 , and the limiting step 62 is located between the limiting flange 63 and the limiting member 60 , thereby limiting the axial displacement of the insertion shaft 50 .

[0088] An alternative to Figures 2 and 18 is provided. As shown in Figure 20, the plug shaft 50 is rotatably arranged on the second base 21 of the second connecting component 20, and the limiting member 60 is correspondingly arranged on the second connecting component 20 and sleeved on the plug shaft 50. At this time, the limiting member 60 is used to limit the plug shaft 50 to the second base 21, so that the plug shaft 50 will not be displaced axially along the plug shaft 50 relative to the second base 21. In one example, the plug shaft 50 is provided with a limiting groove 61 along the circumference, and a limiting step 62 is provided at a corresponding position on the inner side wall of the second base 21. The inner side wall of the limiting member 60 is accommodated in the limiting groove 61, and the outer side wall of the limiting member 60 is abutted against the limiting step 62 of the second base 21.

[0089] Please refer to FIG. 22 . In some embodiments, the insert shaft 50 and the sleeve 40 are fixed in a spline manner.

[0090] Specifically, a spline structure can be set on the outer wall of the plug shaft 50, and a corresponding spline groove can be set on the inner wall of the sleeve 40. When the plug shaft 50 and the sleeve 40 are plugged in, the spline structure and the spline groove are fixedly matched, so that the plug shaft 50 and the sleeve 40 will not rotate relative to each other.

[0091] In some embodiments, the insertion shaft 50 and the shaft sleeve 40 are fixed in the form of a rotation-stopping special-shaped groove.

[0092] Specifically, a special-shaped anti-rotation structure can be provided on the outer sidewall of the insert shaft 50. The special-shaped anti-rotation structure can be configured by configuring the portion of the insert shaft 50 that connects to the sleeve 40 as a polygonal cylinder, with the edges of the outer sidewall of the polygonal cylinder configured as protrusions. A corresponding special-shaped anti-rotation groove can be provided on the inner sidewall of the sleeve 40. The special-shaped anti-rotation groove can be configured to be compatible with the polygonal cylinder containing the protrusions, that is, the inner sidewall of the sleeve 40 is configured as a polygonal hollow cylinder, with the edges of the inner sidewall of the cylinder configured as recessed structures. When the insert shaft 50 is connected to the sleeve 40, the special-shaped anti-rotation structure and the special-shaped anti-rotation groove are fixedly secured, preventing the insert shaft 50 and the sleeve 40 from rotating relative to each other.

[0093] Referring to Figure 2 , in certain embodiments, the propeller connection device 100 further includes a damping member 70 connected to the plug shaft 50 or the sleeve 40. The damping member 70 is used to provide a damping force against the rotation of the second connection assembly 20 relative to the first connection assembly 10. This ensures steering damping or pitching damping, providing a good user experience.

[0094] Furthermore, the thruster connection device 100 may further include a damping adjuster 80 . The damping adjuster 80 is connected to the damping member 70 to adjust the rotational damping provided by the damping member 70 .

[0095] 8 and 12 , in some embodiments, the insert shaft 50 is rotatably engaged with the sleeve 40 . The damping member 70 is connected to one of the insert shaft 50 and the sleeve 40 and provides rotational damping to the other of the insert shaft 50 and the sleeve 40 .

[0096] In one embodiment, as shown in FIG8 , a damping member 70 is connected to the plug shaft 50 to provide rotational damping to the sleeve 40, thereby providing a damping force for the rotation of the second connecting assembly 20 relative to the first connecting assembly 10. In this case, the damping member 70 can be connected to the outer peripheral side surface of the plug shaft 50, and the damping adjuster 80 can be disposed on the outer end surface of the plug shaft 50. The damping adjuster 80 is connected to the damping member 70 to adjust the rotational damping provided by the damping member 70 to the inner side surface of the sleeve 40. Alternatively, the damping member 70 can also be connected to the sleeve 40 to provide rotational damping to the plug shaft 50, thereby providing a damping force for the rotation of the second connecting assembly 20 relative to the first connecting assembly 10. In this case, the damping member 70 is connected to the inner side surface of the sleeve 40, and the damping adjuster 80 can be disposed inside the sleeve 40. The damping adjuster 80 is connected to the damping member 70 to adjust the rotational damping provided by the damping member 70 to the outer side surface of the plug shaft 50. It should be noted that the outer wall of the damping adjuster 80 can be provided with a threaded structure, and a corresponding threaded structure is provided on the inner wall of the sleeve 40. By rotating the damping adjuster 80, the damping adjuster 80 is moved axially along the insertion shaft 50 via the threaded structure, thereby driving the damping member 70 to move axially along the insertion shaft 50, thereby adjusting the extrusion deformation of the damping member 70 in the radial direction of the insertion shaft 50, thereby adjusting the rotational friction resistance provided to the inner surface of the sleeve 40 or the outer surface of the insertion shaft 50. In this way, when the second connecting assembly 20 rotates relative to the first connecting assembly 10, vibration during rotation can be reduced, providing a better user experience.

[0097] Referring to Figures 14 and 20 , in certain embodiments, the insertion shaft 50 and the sleeve 40 are relatively fixed after being plugged in. The first connecting assembly 10 includes a first base 11 fixed to one of the insertion shaft 50 and the sleeve 40, and the second connecting assembly 20 includes a second base 21 rotatably engaged with the other of the insertion shaft 50 and the sleeve 40. The damping member 70 is connected to the second base 21 and provides rotational damping to the insertion shaft 50 or the sleeve 40 that is rotationally engaged with the second base 21, or is connected to the insertion shaft 50 or the sleeve 40 that is rotationally engaged with the second base 21 and provides rotational damping to the second base 21.

[0098] An embodiment is provided, as shown in FIG14 , in which the first connecting assembly 10 is provided with a first base 11 fixed to the plug shaft 50, and the second connecting assembly 20 is provided with a second base 21 rotatably engaged with the shaft sleeve 40. The damping member 70 is connected to the second base 21 and provides rotational damping to the shaft sleeve 40 rotatably engaged with the second base 21. The second base 21 is provided with a socket rotatably engaged with the shaft sleeve 40, and the damping member 70 can be accommodated in the socket of the second base 21 and connected to the inner wall of the socket. The second base 21 is also provided with an adjustment screw hole connected to the socket, and a damping adjuster 80 can be set in the adjustment screw hole of the second base 21. The damping adjuster 80 is connected to the damping member 70 to adjust the rotational damping provided by the damping member 70 to the outer side surface of the shaft sleeve 40. Alternatively, the damping member 70 is connected to the shaft sleeve 40 and provides rotational damping to the inner wall of the socket of the second base 21. At this time, the damping member 70 may be connected to the outer peripheral side of the sleeve 40 , and the damping adjuster 80 is connected to the damping member 70 to adjust the rotation damping provided by the damping member 70 to the inner side of the insertion hole of the second base 21 .

[0099] An embodiment is provided, as shown in FIG20 , in which a first connecting assembly 10 is provided with a first base 11 fixedly connected to a sleeve 40. The sleeve 40 is relatively fixed after being plugged into the plug shaft 50. A second connecting assembly 20 is provided with a second base 21 that is rotatably engaged with the plug shaft 50. A damping member 70 is connected to the second base 21 and provides rotational damping for the plug shaft 50 that is rotatably engaged with the second base 21. The second base 21 is provided with a socket that is rotatably engaged with the plug shaft 50. The damping member 70 can be accommodated in the socket of the second base 21 and connected to the inner wall of the socket. The second base 21 is also provided with an adjustment screw hole connected to the socket. A damping adjuster 80 can be set in the adjustment screw hole of the second base 21. The damping adjuster 80 is connected to the damping member 70 to adjust the rotational damping provided by the damping member 70 on the outer surface of the plug shaft 50. Alternatively, the damping member 70 is connected to the plug shaft 50 and provides rotational damping for the second base 21. At this time, the damping member 70 may be connected to the outer peripheral side of the insertion shaft 50 , and the damping adjuster 80 is connected to the damping member 70 to adjust the rotation damping provided by the damping member 70 to the inner side of the insertion hole of the second base 21 .

[0100] In one embodiment, as shown in Figures 16 and 18 , the insertion shaft 50 and the sleeve 40 are relatively fixed after being plugged in. A first connecting assembly 10 includes a first base 11 that rotatably engages with one of the insertion shaft 50 and the sleeve 40, and a second connecting assembly 20 includes a second base 21 that is fixed to the other of the insertion shaft 50 and the sleeve 40. A damping member 70 is connected to the first base 11 and provides rotational damping to the insertion shaft 50 or the sleeve 40 that is rotationally engaged with the first base 11, or is connected to the insertion shaft 50 or the sleeve 40 that is rotationally engaged with the first base 11 and provides rotational damping to the first base 11.

[0101] Specifically, as shown in Figure 18, if the first connecting component 10 is provided with a first base 11 that can rotatably cooperate with the plug shaft 50, the second connecting component 20 is provided with a second base 21 fixed to the sleeve 40. The damping member 70 is connected to the first base 11 and provides rotational damping to the plug shaft 50 that is rotatably cooperated with the first base 11. The first base 11 is provided with a socket that is rotatably cooperated with the plug shaft 50. The damping member 70 can be accommodated in the socket of the first base 11 and connected to the inner wall of the socket. The first base 11 is also provided with an adjusting screw hole connected to the socket. The damping adjuster 80 can be set in the adjusting screw hole of the first base 11. The damping adjuster 80 is connected to the damping member 70 to adjust the rotational damping provided by the damping member 70 to the outer side surface of the plug shaft 50. Alternatively, the damping member 70 is connected to the plug shaft 50 and provides rotational damping to the first base 11. At this time, the damping member 70 can be connected to the outer peripheral side of the insertion shaft 50 , and the damping adjuster 80 is connected to the damping member 70 to adjust the rotation damping provided by the damping member 70 to the inner side of the insertion hole of the first base 11 .

[0102] As shown in Figure 16, the first connecting component 10 is provided with a first base 11 that is rotatably engaged with the sleeve 40, and the second connecting component 20 is provided with a second base 21 that is fixed to the plug shaft 50. The damping member 70 is connected to the first base 11 and provides rotational damping to the sleeve 40 that is rotatably engaged with the first base 11. The first base 11 is provided with a socket that is rotatably engaged with the sleeve 50. The damping member 70 can be accommodated in the socket of the first base 11 and connected to the inner wall of the socket. The first base 11 is also provided with an adjusting screw hole connected to the socket. The damping adjuster 80 can be set in the adjusting screw hole of the first base 11. The damping adjuster 80 is connected to the damping member 70 to adjust the rotational damping provided by the damping member 70 to the outer side surface of the sleeve 40. Alternatively, the damping member 70 is connected to the sleeve 40 and provides rotational damping to the first base 11. At this time, the damping member 70 may be connected to the outer peripheral side of the sleeve 40 , and the damping adjuster 80 is connected to the damping member 70 to adjust the rotation damping provided by the damping member 70 to the inner side of the insertion hole of the first base 11 .

[0103] 2 , in some embodiments, the damping member 70 includes a wedge-shaped structure disposed circumferentially around the insertion shaft 50. The damping adjuster 80 adjusts the axial position of the damping member 70 along the insertion shaft 50 to adjust the radial pressing force of the wedge-shaped structure along the insertion shaft 50.

[0104] Specifically, the wedge-shaped structure can be made of plastic. The wedge-shaped structure squeezes the plug shaft 50 and the first base 11 or the second base 21 that rotates with the plug shaft 50, and the deformation of the wedge-shaped structure generates a radial pressing force along the plug shaft 50. The damping adjuster 80 adjusts the axial position of the damping member 70 along the plug shaft 50 to adjust the radial pressing force of the wedge-shaped structure along the plug shaft 50, thereby adjusting the rotational damping provided by the damping member 70. For example, in Figure 2, the damping adjuster 80 adjusts the damping member 70 to move upward along the plug shaft 50, and the radial pressing force of the wedge-shaped structure along the plug shaft 50 increases, thereby increasing the rotational damping provided by the damping member 70. The damping adjuster 80 adjusts the damping member 70 to move downward along the plug shaft 50, and the radial pressing force of the wedge-shaped structure along the plug shaft 50 decreases, thereby reducing the rotational damping provided by the damping member 70.

[0105] In certain embodiments, the damping member 70 may also include a wedge-shaped structure disposed circumferentially around the shaft sleeve 40. The wedge-shaped structure compresses the shaft sleeve 40 and the first base 11 or the second base 21 that rotatably engages with the shaft sleeve 40. The wedge-shaped structure deforms to generate a compressive force along the radial direction of the shaft sleeve 40. The damping adjuster 80 adjusts the axial position of the damping member 70 along the shaft sleeve 40 to adjust the compressive force of the wedge-shaped structure along the radial direction of the shaft sleeve 40, thereby adjusting the rotational damping provided by the damping member 70.

[0106] 2 and 23 , in some embodiments, the limiting mechanism 30 is disposed on the shaft sleeve 40. Specifically, when the first connecting assembly 10 is provided with the shaft sleeve 40, the limiting mechanism 30 is disposed on the shaft sleeve 40 of the first connecting assembly 10; and when the second connecting assembly 20 is provided with the shaft sleeve 40, the limiting mechanism 30 is disposed on the shaft sleeve 40 of the second connecting assembly 20 (as shown in FIG. 2 ).

[0107] 24 , in some embodiments, the locking assembly 31 includes a locking member 311 that slides and retracts on the inner wall of the sleeve 40 , and the insertion shaft 50 is provided with a locking groove 43 that cooperates with the locking member 311 .

[0108] In some embodiments, the sleeve 40 has a side surface 42 parallel to the advancing direction, and the locking member 311 slides and retracts along the inner wall of the sleeve 40 in a direction perpendicular to the side surface 42 .

[0109] Specifically, when the insertion shaft 50 is plugged into the sleeve 40, the locking member 311 on the inner wall of the sleeve 40 aligns with the locking groove 43 on the insertion shaft 50. A portion of the locking member 311 can slide from the inner wall of the sleeve 40 in a direction perpendicular to the side of the sleeve 40 and extend into the locking groove 43, thereby preventing the insertion shaft 50 from axially displacing relative to the sleeve 40, thereby locking the insertion shaft 50 with the sleeve 40 and, in turn, locking the first connecting assembly 10 with the second connecting assembly 20. In other embodiments, the locking member 3111 can also slide and retract along the inner wall of the sleeve 40 in a direction parallel to the side 42 or in any other direction.

[0110] In some embodiments, the end of the insertion shaft 50 for inserting into the sleeve 40 is formed with a first chamfered structure, and the end of the locking member 311 near the insertion shaft 50 is formed with a second chamfered structure. When the insertion shaft 50 is inserted into the sleeve 40, the first chamfered structure cooperates with the second chamfered structure.

[0111] Specifically, when there is no inserted shaft 50 extending into the sleeve 40, the locking member 311 protrudes from the inner wall of the sleeve 40. When the inserted shaft 50 begins to extend into the sleeve 40, the locking member 311 contacts the end of the inserted shaft 50 extending into the sleeve 40. At this time, the first chamfered structure of the inserted shaft 50 cooperates with the second chamfered structure of the locking member 311, and an interaction force is generated between the first chamfered structure and the second chamfered structure. Since the locking member 311 can slide and retract, the locking member 311 receives the force provided by the first chamfered structure and slides and retracts into the inner wall of the sleeve 40. The inserted shaft 50 continues to extend into the sleeve 40, and the locking member 311 is subjected to the force of the side wall of the inserted shaft 50 and stays in the inner wall of the sleeve 40. When the insertion shaft 50 is fully inserted into the shaft sleeve 40, the locking member 311 and the locking groove 43 are in corresponding positions. The locking member 311 is no longer subjected to the force and can automatically slide into the locking groove 43, so that the insertion shaft 50 and the shaft sleeve 40 are locked, and then the first connecting component 10 and the second connecting component 20 are locked.

[0112] 23 and 24 , in some embodiments, the locking assembly 31 further includes a spring 312. The spring 312 is used to provide a restoring force for the locking member 311 to return to the locked position after the first connecting assembly 10 and the second connecting assembly 20 are separated.

[0113] Specifically, one end of the spring 312 is connected to the locking piece 311, and the other end is connected to the sleeve 40. When the inserted shaft 50 has not yet been inserted into the sleeve 40, the spring 312 is in a pre-compression state, and the locking piece 311 protrudes from the inner wall of the sleeve 40. When the inserted shaft 50 begins to extend into the sleeve 40, an interaction force is generated between the first chamfered structure and the second chamfered structure. The locking piece 311 receives the force provided by the first chamfered structure and slides and shrinks into the inner wall of the sleeve 40. At this time, the spring 312 is in a compressed state. The inserted shaft 50 continues to extend into the sleeve 40, and the locking piece 311 is subjected to the force of the side wall of the inserted shaft 50 and stays in the inner wall of the sleeve 40. At this time, the spring 312 remains in a compressed state. When the inserted shaft 50 is fully inserted into the sleeve 40, the locking piece 311 and the locking groove 43 are in corresponding positions. The locking member 311 is no longer subject to the force exerted by the insertion shaft 50, and the spring 312 returns to its pre-compressed state. Under the action of the restoring force of the spring 312, the locking member 311 slides into the locking groove 43. At this point, the locking member 311 is in the locked position, locking the insertion shaft 50 with the shaft sleeve 40. To remove the insertion shaft 50 from the shaft sleeve 40, the user operates the control member 321 to compress the spring 312, causing the locking member 311 to slide back into the inner wall of the shaft sleeve 40. When the insertion shaft 50 and the shaft sleeve 40 are completely disassembled, that is, when the first connecting assembly 10 is separated from the second connecting assembly 20, the spring 312 returns to its pre-compressed state, and the locking member 311 returns to its locked position under the action of the restoring force of the spring 312.

[0114] 3 , in some embodiments, the sleeve 40 has a shaft hole 44 for detachably inserting the shaft 50 and an operating portion 41 staggered from the shaft hole 44. The unlocking assembly 32 is at least partially disposed on the operating portion 41 to receive the unlocking operation.

[0115] Specifically, the insertion shaft 50 extending into the shaft sleeve 40 refers to the insertion shaft 50 extending into the shaft hole 44 of the shaft sleeve 40. The operating portion 41 is the component that allows the user to operate the thruster connection device 100. The unlocking assembly 32 is partially or entirely disposed on the operating portion 41 to receive the unlocking operation, thereby maintaining the locking assembly 31 in the unlocked state.

[0116] 23 and 25 , in some embodiments, the unlocking assembly 32 includes a control member 321. The control member 321 is connected to the locking assembly 31 and is configured to receive an unlocking force and drive the locking assembly 31 to an unlocked state.

[0117] Specifically, when the insertion shaft 50 and the sleeve 40 are in the plugged state, the locking assembly 31 locks the plugging of the first connecting assembly 10 and the second connecting assembly 20. When the first connecting assembly 10 and the second connecting assembly 20 need to be disassembled, the user applies an unlocking force to the control member 321 through the operating portion 41. The control member 321 receives the unlocking force and releases the locking assembly 31, entering the unlocked state.

[0118] In some embodiments, the control member 321 is movably engaged with the sleeve 40, and the locking assembly 31 includes a locking member 311 fixed to the control member 321. The control member 321 can drive the locking member 311 to move to a position where it is locked with the insertion shaft 50 or unlocked.

[0119] 3 and 23 to 25 , in some embodiments, the sleeve 40 has a side surface 42 parallel to the advancing direction, the locking member 311 is slidably fitted in the sleeve 40 , and the control member 321 is a press member disposed on the side surface 42 for pressing.

[0120] Specifically, the pressing member is fixedly connected to the locking member 311, and the pressing member can drive the locking member 311 to slide, so that the locking member 311 moves to a position where it is locked with the insertion shaft 50 or unlocked from the insertion shaft 50. For example, when it is necessary to remove the insertion shaft 50 from the shaft sleeve 40, the user can press the pressing member to control the locking member 311 to slide back into the inner wall of the shaft sleeve 40, that is, to a position where the insertion shaft 50 is unlocked.

[0121] Please refer to Figure 26. In some embodiments, based on the embodiment of Figure 3, an embodiment is provided in which the pressing member is replaced by a pulling member 3211. The sleeve 40 has a side surface 42 parallel to the propulsion direction, the locking member 311 is slidably fitted in the sleeve 40, and the control member 321 is a pulling member 3211 that is configured on the side surface 42 and can be pulled.

[0122] Specifically, the pulling member 3211 is disposed on a side surface 42 of the sleeve 40 adjacent to the snap-fit ​​end of the locking member 311. The pulling member 3211 can drive the locking member 311 to slide, causing the locking member 311 to move to a position where it is locked with or unlocked from the insertion shaft 50. For example, as shown in FIG26 , a first transmission mechanism 313 is connected between the pulling member 3211 and the locking member 311. When the insertion shaft 50 needs to be removed from the sleeve 40, the user can pull the pulling member 3211 in a direction perpendicular to the side surface 42 of the sleeve 40, causing the first transmission mechanism 313 to drive the locking member 311 to slide and retract back into the inner wall of the sleeve 40, thereby unlocking the insertion shaft 50.

[0123] Please refer to Figure 27. In some embodiments, based on the embodiment of Figure 3, an embodiment is provided in which the pressing member is replaced by a knob 3212, the sleeve 40 has a side parallel to the propulsion direction, the locking member 311 slides in conjunction with the sleeve 40, and the control member 321 is a rotatable knob configured on the side 42.

[0124] Specifically, the knob 3212 can drive the locking member 31 to slide, causing the locking member 311 to move to a position where it is locked with the plug shaft 50 or unlocked with the plug shaft 50. As shown in Figure 27, the second transmission mechanism 314 is connected between the knob 3212 and the locking member 311. The second transmission mechanism 314 transmits the unlocking force of the knob 3212 to the locking member 311 and converts the rotational torque of the knob 3212 into a linear torque of the locking member 311, so that the locking member 311 slides and unlocks in a linear direction. It is understood that when the knob 3212 is rotated in different directions, the locking member 311 can be set to a position where the plug shaft 50 is locked or unlocked. For example, when the knob 3212 is rotated in a clockwise direction, the locking member 311 can slide to a position where the plug shaft 50 is unlocked. When the inserted shaft 50 needs to be removed from the sleeve 40, the user can rotate the knob 3212 clockwise to control the locking member 311 to slide back into the inner wall of the sleeve 40, thereby unlocking the inserted shaft 50. Alternatively, the locking member 311 can be configured to slide to a position that unlocks the inserted shaft 50 when the knob 3212 is rotated counterclockwise. When the inserted shaft 50 needs to be removed from the sleeve 40, the user can rotate the knob 3212 counterclockwise to control the locking member 311 to slide back into the inner wall of the sleeve 40, thereby unlocking the inserted shaft 50.

[0125] Please refer to Figure 28. In some embodiments, based on the embodiment of Figure 3, an embodiment is provided in which the pressing member is replaced by a sliding button 3213, the sleeve 40 has a side surface parallel to the propulsion direction, the locking member 311 slides in conjunction with the sleeve 40, and the control member 321 is a sliding button 3213 configured on the side surface 42.

[0126] Specifically, the sliding button 3213 can drive the locking member 311 to slide, so that the locking member 311 moves to a position where it is locked with the plug shaft 50 or unlocked from the plug shaft 50. As shown in Figure 28, the sliding button 3213 and the locking member 311 are connected to the third transmission mechanism 315. The third transmission mechanism 315 transmits the unlocking force of the sliding button 3213 to the locking member 311 and converts the linear torque of the sliding button 3213 along the side 42 into the linear torque of the locking member 311, so that the locking member 311 slides along the linear direction to unlock. It is understandable that, for example, when the plug shaft 50 needs to be removed from the sleeve 40, the user can control the locking member 311 to slide back into the inner wall of the sleeve 40 by sliding the sliding button 3213 along the side 42 of the sleeve 40, that is, the position where the plug shaft 50 is unlocked.

[0127] Referring to Figures 23 and 25, in some embodiments, the unlocking assembly 32 includes a retaining member 322. When the locking assembly 31 is in the unlocked state, the retaining member 322 can move to connect with the locking assembly 31 to limit the movement of the locking assembly 31 so that the locking assembly 31 remains in the unlocked state.

[0128] Specifically, when the first connecting component 10 and the second connecting component 20 need to be disassembled, the user applies an unlocking force to the control member 321 through the operating portion 41. The control member 321 receives the unlocking force to release the locking component 31 and enter the unlocked state. When the locking component 31 enters the unlocked state, it will be connected to the retaining member 322. For example, a notch 3221 can be provided on the retaining member 322, and the notch 3221 is located at one end of the retaining member 322 close to the locking member 311 (when the insertion shaft 50 is inserted into the shaft sleeve 40, the retaining member 322 moves until the notch 3221 is located on the sliding path of the locking member 311). A boss 3222 is provided on the locking member 311, and the boss 3222 is located between the control member 321 and the snap-on end of the locking member 311. When the locking assembly 31 is unlocked, the boss 3222 slides along with the locking member 311, sliding into the notch 3221 located in the sliding path of the locking member 311 and engaging with it, thereby connecting the locking assembly 31 with the retaining member 322 and placing the unlocking assembly 32 in the unlocked and retained state. The retaining member 322 restricts the movement of the locking assembly 31, thereby maintaining the locking assembly 31 in the unlocked state, making it easier for the user to remove the second connecting assembly 20 from the first connecting assembly 10.

[0129] 23 and 25 , in some embodiments, the retaining member 322 is rotatably connected to the shaft sleeve 40. In this case, the unlocking assembly 32 further includes a torsion spring 323, which is used to provide a reset force for the retaining member 322 to rotate and release the locking assembly 31 after the insertion shaft 50 is separated from the shaft sleeve 40.

[0130] Specifically, the retaining member 322 is rotatably connected to the sleeve 40 via a connecting rod 3223 connected to the sleeve 40. One end of the connecting rod 3223 is connected to the side of the sleeve 40 where the control member 321 is provided, and the other end is connected to the side of the sleeve 40 opposite to the control member 321. When the plug-in shaft 50 is not inserted, the torsion spring 323 is in a pre-twisted state. When the plug-in shaft 50 is inserted into the sleeve 40, the torsion spring is in a torsion state, providing a torsional torque to hold the retaining member 322 against the plug-in shaft 50. When the plug-in shaft 50 and the sleeve 40 are unlocked, but the plug-in shaft 50 has not yet separated from the sleeve 40, the retaining member 322 is connected to the locking assembly 31. Under the action of the torsional torque, the retaining member 322 can limit the movement of the locking assembly 31. After the plug-in shaft 50 is separated from the sleeve 40, the unlocking assembly 32 needs to release the unlocked state of the locking assembly 31 and return to the state when the plug-in shaft 50 is not inserted. The torsion spring 323 recovers its deformation to the pre-twisted state, and can provide a restoring force to the retaining member 322, so that the end of the retaining member 322 that originally supported the plug shaft 50 rotates into the shaft hole (which will be described in detail later), and the slot 3221 of the retaining member 322 rotates in the opposite direction and disengages from the boss 3222 of the locking assembly 31, thereby releasing the positioning of the retaining member 322 and the locking assembly 31, and the unlocked state of the locking assembly 31 can be released.

[0131] 29 and 30 , in some embodiments, the retaining member 322 is slidably connected to the shaft sleeve 40. In this case, the unlocking assembly 32 may further include a rectangular spring 3225, which is used to provide a restoring force for the retaining member 322 to slide and release the locking assembly 31 after the insertion shaft 50 is separated from the shaft sleeve 40.

[0132] Specifically, the retaining member 322 includes a slider 3224, a rectangular spring 3225, a gear 3226, and a first transmission member 3227. The slider 3224 is slidably connected to the sleeve 40 and is used to abut against the insertion shaft 50 to sense the insertion of the insertion shaft 50. When the insertion of the insertion shaft 50 is limited, the slider 3224 retracts relative to the inner wall of the shaft hole. The gear 3226 then drives the first transmission member 3227 toward the locking member 311, so that the notch 3221 on the first transmission member 3227 engages with the boss 3222 of the locking member 311. The slider 3224 and the gear 3226 are aligned via a linear rack, and the first transmission member 3227 and the gear 3226 are aligned via a linear rack, thereby causing the slider 3224 and the first transmission member 3227 to move in opposite directions. When the insertion shaft 50 is inserted, the rectangular spring 3225 is in a pre-compressed state. During the insertion of the shaft 50 into the sleeve 40, the shaft 50 compresses the third chamfered structure of the slider 3224, generating an interaction force that causes the slider 3224 to move, compressing the rectangular spring 3225 and forcing the first transmission member 3227 toward the locking assembly 31. When the locking assembly 31 enters the unlocked state, the first transmission member 3227 engages with the locking member 311 of the locking assembly 31, maintaining the unlocked state. After the shaft 50 is separated from the sleeve 40, the unlocking assembly 32 must release the unlocked state of the locking assembly 31, returning it to the state without the shaft 50 inserted. At this point, the third chamfered structure is no longer subject to the force of the shaft 50, and the rectangular spring 3225 returns to its pre-compressed state, providing a restoring force to the inner wall of the slider 3224 extending out of the shaft hole, causing the first transmission member 3227 to slide in the opposite direction. This releases the first transmission member 3227 from the locking assembly 31, releasing the locking assembly 31 from its unlocked state.

[0133] 3 and 23 , in some embodiments, the sleeve 40 is provided with a shaft hole 44 for removably inserting the insertion shaft 50. When the insertion shaft 50 is removed from the sleeve 40, one end of the retaining member 322 extends into the shaft hole 44, and the other end disengages from the locking assembly 31, releasing the locking assembly 31 from its position.

[0134] Specifically, when the insertion shaft 50 is plugged into the shaft hole 44, the end of the retaining member 322 away from the locking member 311 is limited by the side wall of the insertion shaft 50 and maintains a state in which its length direction is roughly parallel to the insertion shaft 50. At this time, for example, the torsion spring 323 is in a deformed state. When the insertion shaft 50 is separated from the shaft sleeve 40, the side wall of the insertion shaft 50 has no limit on the end of the retaining member 322 away from the locking member 311. The torsion spring 323 recovers its deformation to the pre-twisted state, providing a restoring force to the retaining member 322, so that the end of the retaining member 322 away from the locking member 311 extends into the shaft hole 44, and the other end is separated from the locking assembly 31, thereby releasing the positioning of the locking assembly 31.

[0135] 2 , 31 , and 32 , in some embodiments, the limiting mechanism 30 is disposed on the insertion shaft 50. Specifically, when the first connecting assembly 10 is provided with the insertion shaft 50, the limiting mechanism 30 is disposed on the insertion shaft 50 of the first connecting assembly 10; and when the second connecting assembly 20 is provided with the insertion shaft 50, the limiting mechanism 30 is disposed on the insertion shaft 50 of the second connecting assembly 20.

[0136] In some embodiments, the insertion shaft 50 has an operating portion 41 located outside the shaft sleeve 40 , and the unlocking assembly 32 is at least partially disposed on the operating portion 41 to receive an unlocking operation.

[0137] Specifically, the operating portion 41 is a component that a user can operate the thruster connection device 100. The unlocking assembly 32 is partially or entirely disposed on the operating portion 41 to receive an unlocking operation, thereby keeping the locking assembly 31 in an unlocked state.

[0138] In some embodiments, the unlocking assembly 32 includes a control member 321. The control member 321 is assembled to the operating portion 41 and connected to the locking assembly 31, and is used to receive the unlocking force and drive the locking assembly 31 to the unlocked state.

[0139] Specifically, when the insertion shaft 50 and the sleeve 40 are in the plugged state, the locking assembly 31 locks the plugging of the first connecting assembly 10 and the second connecting assembly 20. When the first connecting assembly 10 and the second connecting assembly 20 need to be disassembled, the user applies an unlocking force to the control member 321 through the operating portion 41. The control member 321 receives the unlocking force and releases the locking assembly 31, entering the unlocked state.

[0140] It can be understood that, based on the embodiment of Figure 23, the locking assembly 31 slidingly set on the sleeve 40 is replaced by the locking assembly 31 slidingly set on the plug shaft 50 (as shown in Figures 31 and 32), that is, the plug shaft 50 is provided with a slide groove along the vertical axis, and an inner cavity connected to the slide groove, the base of the plug shaft 50 is provided with a pressing groove connected to the inner cavity, the control member 321 can be pressed to fit in the pressing groove, and the inner cavity is provided with a second transmission member 316 connecting the control member 321 and the locking member 311 to transmit the pressing and sliding of the control member 321 to the locking member 311, driving the locking member 311 to retract to the outer wall of the plug shaft 50, and the locking member 311 is disengaged from the locking groove 43 on the inner wall of the sleeve 40.

[0141] In some embodiments, the unlocking assembly 32 includes a retaining member 322. When the locking assembly 31 is in the unlocked state, the retaining member 322 can move to connect with the locking assembly 31 to limit the movement of the locking assembly 31 so that the locking assembly 31 remains in the unlocked state.

[0142] 23 and 25 is replaced by a retaining member 322 that can be elastically extended on the inner wall of the sleeve 40 and can be elastically extended on the outer wall of the plug shaft 50, and the retaining member 322 can limit the locking member 311 to keep it unlocked, or separate from the locking member 311 to release the unlocking.

[0143] Specifically, when the first connecting assembly 10 and the second connecting assembly 20 need to be disassembled, the user applies an unlocking force to the control member 321 through the operating portion 41. The control member 321 receives the unlocking force and releases the locking assembly 31, entering the unlocked state. When the locking assembly 31 enters the unlocked state, it connects with the retaining member 322. For example, a notch 3221 can be provided on the retaining member 322. The notch 3221 is located at one end of the retaining member 322 near the locking member 311 (when the insertion shaft 50 is inserted into the shaft sleeve 40, the retaining member 322 slides and contracts until the notch 3221 is located on the sliding path of the locking member 311). A boss 3222 is provided on the locking member 311. The boss 3222 is located between the snap-fit ​​end of the locking member 311 and the second transmission member 316. When the locking assembly 31 is unlocked, the boss 3222 slides along with the locking member 311, sliding into the notch 3221 located in the sliding path of the locking member 311 and securing it, thereby connecting the locking assembly 31 with the retaining member 322 and placing the unlocking assembly 32 in the unlocked and retained state. The retaining member 322 restricts the movement of the locking assembly 31, thereby maintaining the locking assembly 31 in the unlocked state, making it easier for the user to remove the second connecting assembly 20 from the first connecting assembly 10.

[0144] In some embodiments, the insertion shaft 50 has a mating portion (not shown) located within the sleeve 40, and the locking assembly 31 has a locking piece 311 that is slidably and telescopically arranged in the mating portion. The inner wall of the sleeve 40 is provided with a locking groove 43 that can cooperate with the locking piece 311.

[0145] Specifically, when the insertion shaft 50 is inserted into the sleeve 40, the locking groove 43 on the inner wall of the sleeve 40 corresponds to the position of the locking member 311 of the insertion shaft 50. Part of the locking member 311 can slide into the locking groove 43 on the inner wall of the sleeve 40 to prevent the insertion shaft 50 from moving axially relative to the sleeve 40, thereby locking the insertion shaft 50 in the sleeve 40 and preventing it from falling out of the sleeve 40 due to vibration or warping.

[0146] In some embodiments, the locking assembly 31 further includes a spring 312. The spring 312 is used to provide a restoring force for the locking member to return to the locked position after the first connecting assembly 10 and the second connecting assembly 20 are separated.

[0147] Specifically, as shown in Figure 32, one end of the spring 312 is connected to the control member 321, and the other end is connected to the second transmission member 316. When the inserted shaft 50 has not yet been inserted into the sleeve 40, the spring 312 is in a pre-compression state, and the locking member 311 protrudes from the outer wall of the inserted shaft 50. When the inserted shaft 50 begins to extend into the sleeve 40, the locking member 311 receives the force provided by the sleeve 40 and slides and shrinks into the inner wall of the matching portion. At this time, the spring 312 is in a compressed state. The inserted shaft 50 continues to extend into the sleeve 40, and the locking member 311 is subjected to the force of the side wall of the sleeve 40 and stays in the inner wall of the matching portion. At this time, the spring 312 remains in a compressed state. When the inserted shaft 50 is fully inserted into the sleeve 40, the locking member 311 and the locking groove 43 are in corresponding positions. The locking member 311 is no longer subject to the force exerted by the sleeve 40, and the spring 312 returns to its pre-compressed state. Under the restoring force of the spring 312, the locking member 311 slides into the locking groove 43. At this point, the locking member 311 is in the locked position, locking the insertion shaft 50 with the sleeve 40. To remove the insertion shaft 50 from the sleeve 40, the user operates the control member 321 to compress the spring 312, causing the locking member 311 to slide back into the inner wall of the mating portion.

[0148] Referring to Figure 33, in some embodiments, the sleeve 40 has an open end for inserting the insertion shaft 50, and a closed end for limiting the insertion of the insertion shaft 50. The sleeve 40 has an air vent 45 at the closed end for venting trapped air during the insertion of the insertion shaft 50 and the sleeve 40.

[0149] Specifically, when the plug-in shaft 50 is plugged into the shaft sleeve 40, the plug-in shaft 50 extends from the open end of the shaft sleeve 40 until the plug-in shaft 50 reaches the closed end of the shaft sleeve 40 for limiting. During the plug-in connection between the plug-in shaft 50 and the shaft sleeve 40, due to the tolerance fit between the plug-in shaft 50 and the shaft sleeve 40, the original air in the shaft sleeve 40 is pushed to the closed end of the shaft sleeve 40 and becomes trapped air. The trapped air will generate resistance to the plug-in shaft 50, so that the user needs to spend more force to complete the plug-in connection between the plug-in shaft 50 and the shaft sleeve 40. An air vent 45 is provided at the closed end of the shaft sleeve 40. During the process of inserting the plug-in shaft 50 into the shaft sleeve 40, the trapped air is discharged from the air vent 45. In this way, the user can complete the plug-in connection between the plug-in shaft 50 and the shaft sleeve 40 more easily.

[0150] 34 , in some embodiments, the shaft sleeve 40 is provided with a water injection port 46 . The water injection port 46 is used to allow liquid to enter the shaft sleeve 40 when the insertion shaft 50 is inserted into the shaft sleeve 40 .

[0151] Specifically, during the actual application of the movable device 1000 for water areas according to the embodiment of the present application, particles such as sand or salt are easily introduced into the sleeve 40, causing the shaft 50 and the sleeve 40 to become stuck and unable to rotate or disassemble. Therefore, it is necessary to clean the particles in the sleeve 40 in a timely manner. A water injection port 46 is provided on the sleeve 40. When the shaft 50 is inserted into the sleeve 40, liquid is poured into the sleeve 40 through the water injection port 46, and the particles can be flushed out of the sleeve 40 without removing the shaft 50 from the sleeve 40. In this way, when the propeller connecting device 100 is stuck with sand or salt, the shaft 50 and the sleeve 40 can be effectively prevented from getting stuck, and the normal function of the propeller 300 can be ensured, so that the user has a better use experience.

[0152] In some embodiments, the sleeve 40 includes a sidewall surrounding the insertion shaft 50, and a water injection port 46 is provided on the sidewall. Specifically, the water injection port 46 can be provided in the middle of the sidewall, corresponding to the middle of the insertion shaft 50 along the axial direction, so as to facilitate flushing of particulate matter out of the sleeve 40.

[0153] Please refer to Figure 35. In some embodiments, the first connecting component 10 is provided with one of the ferrule 93 or the insert plate 94, and the second connecting component 20 is provided with the other of the ferrule 93 or the insert plate 94.

[0154] Specifically, the first connecting assembly 10 can be provided with a ferrule 93, and correspondingly, the second connecting assembly 20 can be provided with an insert plate 94. Alternatively, the first connecting assembly 10 can be provided with an insert plate 94, and correspondingly, the second connecting assembly 20 can be provided with a ferrule 93 (as shown in FIG35 ). The plugging of the ferrule 93 and the insert plate 94 enables the plugging of the first connecting assembly 10 and the second connecting assembly 20.

[0155] In some embodiments, the limiting mechanism 30 is provided on the ferrule 93. Specifically, when the first connecting component 10 is provided with the ferrule 93, the limiting mechanism 30 is provided on the ferrule 93 of the first connecting component 10; when the second connecting component 20 is provided with the ferrule 93, the limiting mechanism 30 is provided on the ferrule 93 of the second connecting component 20.

[0156] In some embodiments, the locking assembly 31 has a locking member 311 that slides and retracts on the inner wall of the sleeve 93, and the insert plate 94 is provided with a locking groove 43 that cooperates with the locking member 311.

[0157] Specifically, the locking member 311 can be slidably extended and retracted by a retractable component such as a spring 312. When the insert plate 94 is plugged into the ferrule 93, the locking member 311 on the inner wall of the ferrule 93 corresponds to the position of the locking groove 43 on the insert plate 94. A portion of the locking member 311 can slide from the inner wall of the ferrule 93 into the locking groove 43, locking the insert plate 94 and the ferrule 93, thereby locking the first connecting assembly 10 and the second connecting assembly 20. When the insert plate 94 and the ferrule 93 need to be disassembled, the locking assembly 31 can slide from the locking groove 43 back to the inner wall of the ferrule 93, releasing the lock between the insert plate 94 and the ferrule 93, thereby releasing the lock between the first connecting assembly 10 and the second connecting assembly 20.

[0158] In some embodiments, the ferrule 93 is provided with an axial hole 44 for detachably inserting the inserting plate 94 and an operating portion 41 staggered from the axial hole 44. The unlocking assembly 32 is at least partially disposed on the operating portion 41 to receive the unlocking operation.

[0159] Specifically, the aforementioned insertion of the insert plate 94 and the ferrule 93 refers to the insertion of the insert plate 94 into the axial hole 44 of the ferrule 93. The operating portion 41 is the component through which the user operates the thruster connection device 100. The unlocking assembly 32 is partially or entirely disposed on the operating portion 41 to receive the unlocking operation, thereby maintaining the locking assembly 31 in the unlocked state.

[0160] In some embodiments, the locking assembly 31 has a locking member 311 slidably disposed on the inner wall of the sleeve 93 , and the insert plate 94 is provided with a locking groove 43 that cooperates with the locking member 311 .

[0161] Specifically, when the insert plate 94 is plugged into the ferrule 93, the locking member 311 on the inner wall of the ferrule 93 aligns with the locking groove 43 on the insert plate 94. A portion of the locking member 311 can slide along the inner wall of the ferrule 93 and extend into the locking groove 43 to prevent the insert plate 94 from moving relative to the ferrule 93, thereby locking the insert plate 94 and the ferrule 93, and further locking the first connecting assembly 10 and the second connecting assembly 20. When the insert plate 94 and the ferrule 93 need to be disassembled, the locking assembly 31 can slide along the inner wall of the ferrule 93 to a position disengaged from the locking groove 43, releasing the lock between the insert plate 94 and the ferrule 93, and further releasing the lock between the first connecting assembly 10 and the second connecting assembly 20.

[0162] In some embodiments, the limiting mechanism 30 is disposed on the plug plate 94. Specifically, when the first connecting assembly 10 is provided with the plug plate 94, the limiting mechanism 30 is disposed on the plug plate 94 of the first connecting assembly 10; when the second connecting assembly 20 is provided with the plug plate 94, the limiting mechanism 30 is disposed on the plug plate 94 of the second connecting assembly 20.

[0163] In some embodiments, the insert plate 94 has an operating portion 41 located outside the sleeve 93, and the unlocking component 32 is at least partially disposed on the operating portion 41 to receive the unlocking operation.

[0164] Specifically, the operating portion 41 is a component that a user can operate the thruster connection device 100. The unlocking assembly 32 is partially or entirely disposed on the operating portion 41 to receive an unlocking operation, thereby keeping the locking assembly 31 in an unlocked state.

[0165] In some embodiments, the insert plate 94 has a mating portion (not shown) located in the sleeve 93, and the locking assembly 31 has a locking piece 311 that is slidably and telescopically arranged in the mating portion. The inner wall of the sleeve 93 is provided with a locking groove 43 that can cooperate with the locking piece 311.

[0166] Specifically, when the insert plate 94 has not yet been inserted into the ferrule 93, the locking member 311 protrudes from the outer wall of the insert plate 94. When the insert plate 94 begins to extend into the ferrule 93, the locking member 311 receives the force provided by the ferrule 93 and slides and retracts into the inner wall of the mating portion. The insert plate 94 continues to extend into the ferrule 93, and the locking member 311 is subjected to the force of the side wall of the ferrule 93 and stays in the inner wall of the mating portion. When the insert plate 94 is fully inserted into the ferrule 93, the locking member 311 and the locking groove 43 are in corresponding positions. The locking member 311 is no longer subjected to the force of the ferrule 93, and a portion of the locking member 311 slides and extends into the locking groove 43 to prevent the insert plate 94 from displacing relative to the ferrule 93. At this time, the locking member 311 is in the locked position, locking the insert plate 94 and the ferrule 93.

[0167] In some embodiments, the first connecting component 10 or the second connecting component 20 is provided with a tilting shaft 92 , and the tilting shaft 92 is spaced apart from the clamping sleeve 93 or the inserting plate 94 .

[0168] In some embodiments, the first connecting assembly 10 or the second connecting assembly 20 is provided with a steering shaft 90 , and the steering shaft 90 is spaced apart from the ferrule 93 or the inserting plate 94 .

[0169] Specifically, in the embodiment of the present application, the first connecting component 10 and the second connecting component 20 are plugged into the plug plate 94 and the clamping sleeve 93, and are relatively fixed after plugging and will not rotate relative to each other. Therefore, the first connecting component 10 or the second connecting component 20 may also be provided with a tilting shaft 92 or a steering shaft 91. For example, as shown in Figure 35, the first connecting component 10 is provided with a tilting shaft 92, and the second connecting component 20 is provided with a steering shaft 91. The first connecting component 10 includes a clamping member 12 and a first steering connecting member 131. The clamping member 12 is used to be installed and fixed on the water area carrier 1001. The first steering connecting member 131 is rotated to connect the clamping member 12 via the tilting shaft 92, and the second connecting component 20 can be tilted relative to the first connecting component 10 via the tilting shaft 92. The second connecting assembly 20 includes a second base 21 and a second steering connector 132. The second steering connector 132 is fixedly connected to the propulsion power unit 200. The second base 21 is rotatably connected to the second steering connector 132 via a steering shaft 91 to enable the propulsion power unit 200 to be steerable. The second base 21 is detachably connected to the first steering connector 131 via a plug plate 94.

[0170] Alternatively, as shown in Figure 36, the first connecting assembly 10 is provided with a steering shaft 91, and the second connecting assembly 20 is provided with a tilting shaft 92. The first connecting assembly 10 includes a clamping member 12 and a first steering connector 131. The clamping member 12 is mounted and fixed on the water body 1001. The first steering connector 131 is rotatably connected to the clamping member 12 via the steering shaft 91. The second connecting assembly 20 can be steered relative to the first connecting assembly 10 via the steering shaft 91. The second connecting assembly 20 includes a second base 21 and a second steering connector 132. The second steering connector 132 is fixedly connected to the propulsion unit 200. The second base 21 is rotatably connected to the second steering connector 132 via the tilting shaft 92 to enable tilting of the propulsion unit 200. The second base 21 is detachably connected to the first steering connector 131 via a plug plate 94. The tilting shaft 92 is used to tilt the propeller 300 up and down to adapt to different water conditions and prevent corrosion and collision of the underwater part of the outboard motor. The steering shaft 90 is used to steer the propeller 300 left or right to adjust its course. Thus, the propeller 300 can be tilted and steered using the tilting shaft 92 and the steering shaft 90, thereby enabling the tilting and steering of the mobile device 1000 in the water area. Of course, in other embodiments, the first connecting assembly 10 can be provided with both the tilting shaft 92 and the steering shaft 91, or the second connecting assembly 20 can be provided with both the tilting shaft 92 and the steering shaft 91, without limitation.

[0171] In some embodiments, the unlocking assembly 32 includes a retaining member 322. The retaining member 322 is used to connect with the locking assembly 31 in the unlocked state when the first connecting assembly 10 and the second connecting assembly 20 are plugged together to position the locking assembly 31.

[0172] Specifically, when the first connecting assembly 10 and the second connecting assembly 20 need to be disassembled, the user controls the locking assembly 31 to unlock through the unlocking assembly 32. When the locking assembly 31 enters the unlocked state, it is connected to the retaining member 322. For example, a notch 3221 can be provided on the retaining member 322, and the notch 3221 is located at one end of the retaining member 322 near the locking member 311 (when the inserting plate 94 is inserted into the ferrule 93, the retaining member 322 moves until the notch 3221 is located on the sliding path of the locking member 311). A boss 3222 is provided on the locking member 311, and the boss 3222 is located between the control member 321 and the snap-fit ​​end of the locking member 311. When the locking assembly 31 is unlocked, the boss 3222 slides along with the locking member 311, sliding into the notch 3221 located in the sliding path of the locking member 311 and securing it, thereby connecting the locking assembly 31 with the retaining member 322 and placing the unlocking assembly 32 in the unlocked and retained state. The retaining member 322 positions the locking assembly 31, restricting its movement and thereby maintaining the locking assembly 31 in the unlocked state, making it easier for the user to remove the second connecting assembly 20 from the first connecting assembly 10.

[0173] In some embodiments, the unlocking assembly 32 further includes a control member 321. The control member 321 is connected to the locking assembly 31 and is configured to receive an unlocking force and drive the locking assembly 31 to an unlocked state.

[0174] Specifically, when the insert plate 94 and the ferrule 93 are in the plugged state, the locking assembly 31 locks the plugging of the first connecting assembly 10 and the second connecting assembly 20. When the first connecting assembly 10 and the second connecting assembly 20 need to be disassembled, the user applies an unlocking force to the control member 321 through the operating portion 41. The control member 321 receives the unlocking force and releases the locking assembly 31, entering the unlocked state.

[0175] In some embodiments, the control member 321 is movably matched with the ferrule 93, and the locking assembly 31 includes a locking member 311 fixed to the control member 321. The control member 321 can drive the locking member 311 to move to a position where it is locked with the inserting plate 94 or unlocked with the inserting plate 94.

[0176] Specifically, the ferrule 93 has a side surface 42 parallel to the direction of advancement, and the locking member 311 slides and fits within the ferrule 93 in a direction perpendicular to the side surface. The control member 321 can be a depressible pressing member, a pullable member, a rotatable knob, or a slidable slider disposed on the side surface 42. For example, a user can press the pressing member to control the locking member 311 to move back into the ferrule 93, thereby unlocking the insert plate 94.

[0177] It should be pointed out that the explanation of the scheme of "the first connecting component 10 is provided with one of the sleeve 40 or the plug shaft 50, and the second connecting component 20 is provided with the other of the sleeve 40 or the plug shaft 50" and related elements (such as the locking component 31 and the unlocking component 32) in the aforementioned embodiment is also applicable to the scheme of "the first connecting component 10 is provided with one of the sleeve 93 or the plug plate 94, and the second connecting component 20 is provided with the other of the sleeve 93 or the plug plate 94" and related elements (such as the locking component 31 and the unlocking component 32) in this embodiment. The difference is that the first connecting component 10 and the second connecting component 20 are relatively fixed after being plugged into the sleeve 93 through the plug plate 94, and will not rotate relative to each other.

[0178] Please refer to Figures 2 and 37. An embodiment of the present application provides a propeller 300, which includes the propeller connecting device 100 and the propulsion power device 200 of any of the above embodiments, and the second connecting component 20 is connected to the propulsion power device 200.

[0179] Specifically, the propulsion power unit 200 may include a propulsion actuator and a propeller. The propulsion actuator may be a propulsion motor. The propulsion actuator is connected to the propeller and is used to drive the propeller to rotate and provide propulsion. The propulsion connection device 100 can be turned to change the direction of the propulsion force of the propeller.

[0180] Please refer to Figures 2 and 37. An embodiment of the present application provides a movable device 1000 in a water area. The movable device 1000 in a water area includes a propeller 300 and a water area carrier 1001. The first connecting component 10 is connected to the water area carrier 1001.

[0181] Specifically, the movable water vehicle 1000 can be any type of water transportation vehicle, such as a commercial ship, passenger ship, yacht, fishing boat, sailboat, or civilian ship. It can also be equipment capable of moving in water, such as water inspection equipment, water management equipment, or water environment monitoring equipment. It can also be equipment such as an underwater robot used for underwater operations, without limitation. The water carrier 1001 can be, for example, a ship hull. The water carrier 1001 can provide a certain amount of buoyancy, allowing the movable water vehicle 1000 to float on the water surface and carry people, objects, or other objects. The propeller 300 is connected to the water carrier 1001 to provide propulsion to propel the water carrier 1001 to rise or turn, etc.

[0182] In summary, in the thruster connection device 100, thruster 300, and movable device 1000 for use in water areas of the embodiment of the present application, when the first connection component 10 and the second connection component 20 are plugged in, the locking component 31 of the limiting mechanism 30 is used to lock the plugging of the first connection component 10 and the second connection component 20. When the first connection component 10 and the second connection component 20 are disassembled, the locking component 31 is released, and the unlocking component 32 of the limiting mechanism 30 is in the unlocked holding state, so that the locking component 31 remains in the unlocked state. When the unlocking component 32 is in the unlocked holding state, the second connection component 20 can receive the disassembly force and be disassembled relative to the first connection component 10. In this way, the thruster connection device 100 can be disassembled conveniently and quickly, while ensuring that the thruster connection device 100 remains stable and does not shake after installation. In addition, the thruster 300 can be smaller and more compact when stored, taking up less space.
