In addition, examples of various specific processes and materials are provided in this application, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0058] Please see Figures 1 to 3 , Figure 37 This application provides a thruster connection device 100. The thruster connection device 100 includes a first connection component 10 for connecting a waterborne carrier 1001, a second connection component 20 for connecting a propulsion power unit 200, and a limiting mechanism 30 disposed 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 into each other. The limiting mechanism 30 has 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 unlock holding state that keeps the locking component 31 in an unlocked state, the unlocked state being the state where the locking component 31 is released from locking. When the unlocking component 32 is in the unlock holding state, the second connection component 20 can receive a disassembly force to disassemble relative to the first connection component 10.

[0059] In the thruster connecting device 100 of this application embodiment, when the first connecting component 10 and the second connecting component 20 are inserted, the locking component 31 of the limiting mechanism 30 is used to lock the insertion of the first connecting component 10 and the second connecting component 20. When the first connecting component 10 and the second connecting component 20 are disassembled, the locking component 31 is released, and the unlocking component 32 of the limiting mechanism 30 is in an unlocked holding state, keeping the locking component 31 in an unlocked state. When the unlocking component 32 is in the unlocked holding state, the second connecting component 20 can receive a disassembly force relative to the first connecting component 10 for disassembly. In this way, the thruster connecting device 100 can be disassembled conveniently and quickly, while ensuring that the thruster connecting device 100 remains stable and does not shake after installation. In addition, the thruster 300 can be stored in a smaller, more compact size, occupying less space. Understandably, by manipulating the unlocking component 32 into the unlocked holding state, the locking component 31 can remain in the unlocked state, thus freeing both hands to disassemble the propulsion power device 200, instead of having one hand constantly applying unlocking force while the other hand applies disassembly force. Since the propeller connecting device 100 connects to the propulsion power device 200, and the propulsion power device 200 is relatively heavy, it is usually inconvenient to disassemble with one hand. However, using both hands to apply force to the propulsion power device 200 for disassembly can improve the efficiency of disassembly and facilitate quick disassembly.

[0060] Specifically, the first connecting assembly 10 can be a lifting clamp, and the water carrier 1001 can be a hull. The first connecting assembly 10 is connected to the water carrier 1001, for example, at the stern of the hull. The second connecting assembly 20 can be a steering bracket, and the second connecting assembly 20 is connected to the propulsion power unit 200. The first connecting assembly 10 and the second connecting assembly 20 are detachably plugged in. The limiting mechanism 30 can be configured on the first connecting assembly 10 or on the second connecting assembly 20 (e.g., ...). Figure 2 (As shown). The limiting mechanism 30 includes a locking component 31 (as shown). Figure 24 (as shown) and unlocking component 32 (as shown) Figure 23(As shown). When the first connecting component 10 and the second connecting component 20 are inserted, the water carrier 1001 is connected to the propulsion power device 200, and the propeller 300 can tilt or turn the water carrier 1001. The locking component 31 can lock the insertion of the first connecting component 10 and the second connecting component 20, so that the first connecting component 10 and the second connecting component 20 will not cause the water carrier 1001 and the propulsion power device 200 to fail due to accidental disengagement. When the first connecting component 10 and the second connecting component 20 are disassembled, the locking component 31 enters the unlocked state, and the locking component 31 releases the locking of the first connecting component 10 and the second connecting component 20. The unlocking component 32 can enter the unlocked holding state, and the unlocking component 32 keeps the locking component 31 in the unlocked state. At this time, the user can provide a disassembly force, and the second connecting component 20 can be disassembled relative to the first connecting component 10 by receiving the disassembly force.

[0061] It should be noted that the first connecting component 10 and the second connecting component 20 are tolerance-fitted. This tolerance fit makes the insertion between the first connecting component 10 and the second connecting component 20 easier and prevents significant wobbling of the second connecting component 20 and its connected propulsion power unit 200 relative to the first connecting component 10. When disassembling the second connecting component 20 relative to the first connecting component 10, because the fit between the first connecting component 10 and the second connecting component 20 has a very small tolerance, a force (such as...) needs to be provided simultaneously on both sides of the second connecting component 20 to disengage it from the first connecting component 10. Figure 1 and Figure 2 (A force applied upwards) is needed to prevent the second connecting component 20 from jamming onto the first connecting component 10. Currently, the user needs both hands to apply disassembly force to the second connecting component 20 simultaneously. Similarly, the locking component 31 also requires manual operation to unlock. In current technology, the locking component 31 requires manual control to maintain its unlocked state, making it impossible for the user to apply disassembly force to the second connecting component 20 with both hands while simultaneously keeping the locking component 31 unlocked. In the pusher connecting device 100 of this embodiment, the user controls the locking component 31 to enter the unlocked state, and the unlocking component 32 maintains the locking component 31 in the unlocked state, allowing the user to apply disassembly force to the second connecting component 20 with both hands. The user can then disassemble the first connecting component 10 and the second connecting component 20 independently, without continuously applying unlocking force to the locking component 31. This makes disassembling the first connecting component and the second connecting component 20 much more convenient.

[0062] Please see Figure 2 and Figure 3 In some embodiments, the first connecting component 10 is provided with one of the bushing 40 or the insert shaft 50, and the second connecting component 20 is provided with the other of the bushing 40 or the insert shaft 50.

[0063] Specifically, the first connecting component 10 may be provided with a bushing 40, and correspondingly, the second connecting component 20 may be provided with a shaft 50. Alternatively, the first connecting component 10 may be provided with a shaft 50, and correspondingly, the second connecting component 20 may be provided with a bushing 40 (e.g., Figure 2 (As shown). The first connecting component 10 and the second connecting component 20 are connected by inserting the insert shaft 50 and the bushing 40.

[0064] In some embodiments, the second connecting component 20 may be rotatable relative to the first connecting component 10 via the insert shaft 50.

[0065] Specifically, if the first connecting component 10 is provided with a shaft 50 and the second connecting component 20 is provided with a bushing 40, the shaft 50 of the first connecting component 10 is inserted into the bushing 40 of the second connecting component 20. If the first connecting component 10 is provided with a bushing 40 and the second connecting component 20 is provided with a shaft 50, the shaft 50 of the second connecting component 20 is inserted into the bushing 40 of the first connecting component 10. The shaft 50 has a lifting shaft (such as...). Figure 4 and Figure 6 (as shown) or steering shaft (such as Figure 8 and Figure 10 The function of the second connecting assembly 20 is such that when a rotational force is applied to the second connecting assembly 20, the second connecting assembly 20 rotates about the axis of the insertion shaft 50 to achieve the steering or tilting of the propeller 300. In this way, the propulsion power unit 200 connected to the second connecting assembly 20 can be steered or tilted relative to the water carrier 1001 connected to the first connecting assembly 10.

[0066] Please see Figures 4 to 7 In some embodiments, the rotation direction of the second connecting component 20 relative to the first connecting component 10 via the insert shaft 50 is the tilting direction of the thruster 300, and the first connecting component 10 or the second connecting component 20 is also provided with a steering shaft 91.

[0067] Specifically, such as Figure 4 and Figure 5 As shown, Figure 5 for Figure 4The disassembly diagram shows the insertion shaft 50 horizontally positioned in the view. The second connecting assembly 20 rotates relative to the first connecting assembly 10 via the insertion shaft 50, thereby causing the propulsion power unit 200 connected to the second connecting assembly 20 to tilt. The rotation of the propulsion power unit 200 around the axis of the insertion shaft 50 constitutes the tilting of the propeller 300. In other words, the rotation of the second connecting assembly 20 relative to the first connecting assembly 10 via the insertion shaft 50 causes the propeller 300 to tilt, for example, tilting upwards or downwards relative to the water surface. The tilting function can be understood as: controlling the angle between the propulsion power unit 200 and the water surface, as well as the height of the propulsion power unit 200 above the water surface during navigation, thus adapting to different water conditions; and when the boat is moored for an extended period without use, tilting the underwater part of the outboard motor out of the water to avoid corrosion and collisions. At this time, the first connecting assembly 10 also has a steering shaft 91 (e.g., Figure 4 As shown in the diagram, for example, a steering shaft 91 is provided at the connection between the first connecting assembly 10 and the water carrier 1001. The first connecting assembly 10 includes a clamping member 12 and a steering connector 13. The clamping member 12 is used to install and fix it on the water carrier 1001, and 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 a plug shaft 50, and can be tilted and rotated relative to the second connecting assembly 20 via the plug shaft 50.

[0068] In another similar embodiment, it provides the same as Figure 4 One alternative, such as Figure 6 and Figure 7 As shown, Figure 7 for Figure 6 The disassembly diagram shows that the second connecting assembly 20 also includes a steering shaft 91 (such as...). Figure 6 As shown in the diagram, 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, and the second base 21 is rotatably connected to the steering connector 13 via the steering shaft 91, so that the propulsion power unit 200 can be steered. The second base 21 is also detachably connected to the first connecting assembly 10 via a plug shaft 50, and can also be tilted and rotated relative to the first connecting assembly 10 via the plug shaft 50.

[0069] exist Figures 4 to 7 In this embodiment, the steering shaft 91 is used to turn the thruster 300 left and right to adjust its course. Thus, the tilting and turning of the thruster 300 can be achieved by the joint of the insert shaft 50 and the steering shaft 91, thereby enabling the tilting and turning of the water-based mobile equipment 1000.

[0070] Please see Figures 8 to 11In some embodiments, the rotation direction of the second connecting component 20 relative to the first connecting component 10 via the insert shaft 50 is the turning direction of the thruster 300, and the first connecting component 10 or the second connecting component 20 is also provided with a lifting shaft 92.

[0071] For details, please refer to the following: Figure 2 , Figure 8 and Figure 9 , Figure 9 for Figure 8 The disassembly diagram shows the insertion shaft 50 vertically positioned in the view. The second connecting assembly 20 rotates relative to the first connecting assembly 10 via the insertion shaft 50, thereby enabling the propulsion power unit 200 connected to the second connecting assembly 20 to steer. The rotation of the propulsion power unit 200 around the axis of the insertion shaft 50 constitutes the steering of the propeller 300. In other words, the rotation of the second connecting assembly 20 relative to the first connecting assembly 10 via the insertion shaft 50 allows the propeller 300 to steer, for example, to the left or right, to adjust its course. At this time, the first connecting assembly 10 also has a tilting shaft 92 (e.g., Figure 8 As shown in the diagram, for example, a lifting shaft 92 is provided at the connection between the first connecting assembly 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 fix the water carrier 1001. The first base 11 is rotatably connected to the clamping member 12 via the lifting shaft 92 to drive the propulsion power device 200 to lift relative to the water carrier 1001. The first base 11 is also detachably connected to the second connecting assembly 20 via a plug shaft 50, and the second connecting assembly 20 can rotate relative to the first base 11 via the plug shaft 50.

[0072] based on Figure 8 An alternative embodiment of the embodiment, such as Figure 10 and Figure 11 As shown, Figure 11 for Figure 10 The disassembly diagram shows that the second connecting assembly 20 is also equipped with a tilting shaft 92, for example, at the connection between the second connecting assembly 20 and the propulsion power device 200. The tilting shaft 92 is used to tilt the propeller 300 up and down. In this way, the tilting and turning of the propeller 300 can be achieved by the insertion shaft 50 and the tilting shaft 92 together, thereby enabling the tilting and turning of the water-based mobile equipment 1000.

[0073] 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 power unit 200 and rotatably connected to the second base 21 via a lifting shaft 92, so as to drive the propulsion power unit 200 to lift relative to the water carrier 1001. The second base 21 is also detachably connected to the first connecting assembly 10 via a plug shaft 50, and the second base 21 can drive the propulsion power unit 200 to turn relative to the first connecting assembly 10 via the plug shaft 50.

[0074] Please see Figure 2 In some embodiments, the first connecting assembly 10 includes a first base 11 for connecting the water carrier 1001, and the second connecting assembly 20 includes a second base 21 for connecting the propulsion power unit 200. The insertion shaft 50 is fixed to one of the first base 11 and the second base 21, and is rotatably engaged with the other of the first base 11 and the second base 21.

[0075] Specifically, the insertion shaft 50 can be fixed to the first base 11 of the first connecting assembly 10 and rotatably engaged with the second base 21 of the second connecting assembly 20. Alternatively, the insertion shaft 50 can be fixed to the second base 21 of the second connecting assembly 20 and rotatably engaged with the first base 11 of the first connecting assembly 10.

[0076] Please see Figure 8 and Figure 12 In some embodiments, the insertion shaft 50 is fixed to one of the first base 11 and the second base 21, and the bushing 40 is fixed to the other of the first base 11 or the second base 21. The insertion shaft 50 and the bushing 40 can be rotatably engaged after being inserted.

[0077] Specifically, if the insert shaft 50 is fixed to the first base 11 of the first connecting assembly 10, then the bushing 40 is fixed to the second base 21 of the second connecting assembly 20 (e.g., Figure 8 (As shown). The insert shaft 50 and the bushing 40 are rotatably coupled after insertion. When the insert shaft 50 rotates, since the insert shaft 50 is fixedly connected to the first base 11, and the first base 11 can be connected to the water carrier 1001 via the clamping member 12, with the first base 11 as a fixed position reference, the bushing 40 and the second base 21 fixedly connected to the bushing 40 rotate relative to the insert shaft 50, thereby realizing the rotation of the second connecting assembly 20 relative to the first connecting assembly 10 via the insert shaft 50.

[0078] based on Figure 8 An alternative embodiment is provided, such as Figure 12 and Figure 13 As shown, Figure 13 for Figure 12 The disassembly diagram shows that if the insert shaft 50 is fixed to the second base 21 of the second connecting assembly 20, then the bushing 40 is fixed to the first base 11 of the first connecting assembly 10. The insert shaft 50 and bushing 40 can rotate after insertion. When the insert shaft 50 rotates, it allows both the insert shaft 50 and the second base 21 fixedly connected to it to rotate, thus enabling the second connecting assembly 20 to rotate relative to the first connecting assembly 10 via the insert shaft 50.

[0079] Please see Figures 14 to 17In some embodiments, the insertion shaft 50 is fixed to one of the first base 11 and the second base 21, and the bushing 40 is rotatably connected to the other of the first base 11 and the second base 21. The insertion shaft 50 and the bushing 40 are fixed relative to each other after insertion.

[0080] Specifically, one embodiment is provided, such as Figure 14 and Figure 15 As shown, Figure 15 for Figure 14 The disassembly diagram shows that the insertion shaft 50 is fixed to the first base 11 of the first connecting assembly 10, and the bushing 40 is rotatably connected to the second base 21 of the second connecting assembly 20. The insertion shaft 50 and bushing 40 are fixed relative to each other after insertion. When the insertion shaft 50 rotates, since the insertion shaft 50 is fixedly connected to the first base 11, and the first base 11 is connected to the water carrier 1001, with the first base 11 as a fixed position reference, the second base 21 rotates relative to the bushing 40 and the insertion shaft 50, thereby enabling the second connecting assembly 20 to rotate relative to the first connecting assembly 10 via the insertion shaft 50.

[0081] based on Figure 14 The embodiments provide an alternative embodiment, such as Figure 16 and Figure 17 As shown, Figure 17 for Figure 16 The diagram shows the disassembly process. The insertion shaft 50 is fixed to the second base 21 of the second connecting assembly 20, and the bushing 40 is rotatably connected to the first base 11 of the first connecting assembly 10. After insertion, the insertion shaft 50 and the bushing 40 are fixed relative to each other. When the insertion shaft 50 rotates, the insertion shaft 50, the bushing 40, and the second base 21 fixedly connected to the insertion shaft 50 can rotate, thereby enabling the second connecting assembly 20 to rotate relative to the first connecting assembly 10 via the insertion shaft 50.

[0082] Please refer to the following: Figure 2 In some embodiments, the first connecting assembly 10 includes a first base 11 for connecting the water carrier 1001, and the second connecting assembly 20 includes a second base 21 for connecting the propulsion power unit 200. A shaft 50 is rotatably connected to one of the first base 11 and the second base 21, and a bushing 40 is fixed to the other of the first base 11 and the second base 21. The shaft 50 and the bushing 40 are fixed relative to each other after insertion.

[0083] In one embodiment, such as Figure 18 and Figure 19 As shown, Figure 19 for Figure 18The disassembly diagram shows that the insertion shaft 50 is rotatably connected to the first base 11 of the first connecting assembly 10, and the bushing 40 is fixed to the second base 21 of the second connecting assembly 20. The insertion shaft 50 and bushing 40 are fixed relative to each other after insertion. When the insertion shaft 50 rotates, the insertion shaft 50, bushing 40, and the second base 21 fixedly connected to the bushing 40 can rotate, allowing the second connecting assembly 20 to rotate relative to the first connecting assembly 10 via the insertion shaft 50.

[0084] In another embodiment, as Figure 18 An alternative to the embodiment, such as Figure 20 and Figure 21 As shown, Figure 21 for Figure 20 The disassembly diagram shows that the insertion shaft 50 is rotatably connected to the second base 21 of the second connecting assembly 20, and the bushing 40 is fixed to the first base 11 of the first connecting assembly 10. The insertion shaft 50 and bushing 40 are relatively fixed after insertion. When the insertion shaft 50 rotates, since the insertion shaft 50 and bushing 40 are relatively fixed after insertion, and the bushing 40 is fixedly connected to the first base 11, which is connected to the water carrier 1001, the second base 21 rotates relative to the insertion shaft 50, thus enabling the second connecting assembly 20 to rotate relative to the first connecting assembly 10 via the insertion shaft 50.

[0085] Please see Figure 2 In some embodiments, the insertion shaft 50 is rotatably disposed on the first connecting assembly 10 or the second connecting assembly 20, and the first connecting assembly 10 or the second connecting assembly 20 is provided with a limiting member 60 that restricts the axial displacement of the insertion shaft 50 relative to the first base 11 or the second base 21 along the insertion shaft 50.

[0086] Specifically, please refer to the following: Figure 2 and Figure 18 , Figure 2 for Figure 18 In the partial cross-sectional schematic diagram of the embodiment, the limiting member 60 can be a ring structure, such as a steel ring or other metal material that can limit movement. The insertion shaft 50 is rotatably disposed on the first base 11 of the first connecting assembly 10, and the limiting member 60 is correspondingly disposed on the first connecting assembly 10 (e.g., Figure 2 and Figure 18 (As shown). At this time, the limiting member 60 is used to limit the insertion shaft 50 to the first base 11, so that the insertion shaft 50 will not be displaced relative to the first base 11 along the axial direction of the insertion shaft 50. In one example, the insertion shaft 50 is provided with a limiting groove 61 in the circumferential direction, and a limiting step 62 is provided at a corresponding position on the inner sidewall of the first base 11. The inner sidewall of the limiting member 60 is accommodated in the limiting groove 61, and the outer sidewall of the limiting member 60 abuts against the limiting step 62 of the first base 11. Figure 2In the middle, the insert shaft 50 is also provided with a limiting flange 63 that is spaced apart 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 insert shaft 50.

[0087] Provide a Figure 2 and Figure 18 Replacement methods, such as Figure 20 As shown, the insertion shaft 50 is rotatably mounted on the second base 21 of the second connecting assembly 20. Correspondingly, the limiting member 60 is mounted on the second connecting assembly 20 and sleeved onto the insertion shaft 50. In this case, the limiting member 60 is used to limit the insertion shaft 50 to the second base 21, preventing the insertion shaft 50 from displacing axially relative to the second base 21. In one example, the insertion shaft 50 has a circumferentially circumferentially provided limiting groove 61, and the inner wall of the second base 21 has a corresponding limiting step 62. The inner wall of the limiting member 60 is accommodated in the limiting groove 61, and the outer wall of the limiting member 60 abuts against the limiting step 62 of the second base 21.

[0088] Please see Figure 22 In some embodiments, the insert shaft 50 and the bushing 40 are fixed in a spline manner.

[0089] Specifically, a spline structure can be provided on the outer wall of the insert shaft 50, and a corresponding spline groove can be provided on the inner wall of the bushing 40. When the insert shaft 50 and the bushing 40 are inserted, the spline structure and the spline groove are fixedly engaged, so that the insert shaft 50 and the bushing 40 will not rotate relative to each other.

[0090] In some embodiments, the insert shaft 50 and the bushing 40 are fixed by an anti-rotation groove.

[0091] Specifically, an anti-rotation irregular structure can be provided on the outer wall of the insert shaft 50. This anti-rotation irregular structure can be a polygonal column where the portion of the insert shaft 50 intersects with the bushing 40, with the edges of the outer wall of the polygonal column being raised. A corresponding anti-rotation irregular groove is provided on the inner wall of the bushing 40. This anti-rotation irregular groove can be a structure that can correspondingly intersect with the polygonal column containing the raised structure; that is, the inner wall of the bushing 40 is a hollow polygonal column, with the edges of the inner wall of the column being recessed. When the insert shaft 50 and the bushing 40 are intersected, the anti-rotation irregular structure and the anti-rotation irregular groove are fixedly engaged, preventing the insert shaft 50 and the bushing 40 from rotating relative to each other.

[0092] Please see Figure 2 In some embodiments, the thruster connection device 100 further includes a damping element 70 connected to the insert shaft 50 or the bushing 40. The damping element 70 provides damping force to the rotation of the second connection assembly 20 relative to the first connection assembly 10. This ensures steering damping or tilting damping, resulting in a better user experience.

[0093] Furthermore, the thruster connection device 100 may also include a damping adjuster 80. The damping adjuster 80 is connected to the damping element 70 to adjust the rotational damping provided by the damping element 70.

[0094] Please see Figure 8 and Figure 12 In some embodiments, the insert shaft 50 and the bushing 40 are rotatably coupled. A damping element 70 is connected to one of the insert shaft 50 and the bushing 40 and provides rotational damping to the other of the insert shaft 50 and the bushing 40.

[0095] One embodiment is provided, such as Figure 8 The damping element 70 is connected to the insert shaft 50, providing rotational damping to the bushing 40, and thus providing damping force to the rotation of the second connecting assembly 20 relative to the first connecting assembly 10. In this case, the damping element 70 can be connected to the outer peripheral side of the insert shaft 50, and the damping adjuster 80 can be disposed on the outer end face of the insert shaft 50. The damping adjuster 80 is connected to the damping element 70 to adjust the rotational damping provided by the damping element 70 to the inner side of the bushing 40. Alternatively, the damping element 70 can also be connected to the bushing 40, providing rotational damping to the insert shaft 50, and thus providing damping force to the rotation of the second connecting assembly 20 relative to the first connecting assembly 10. In this case, the damping element 70 is connected to the inner side of the bushing 40, and the damping adjuster 80 can be disposed inside the bushing 40. The damping adjuster 80 is connected to the damping element 70 to adjust the rotational damping provided by the damping element 70 to the outer side of the insert 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 bushing 40. By rotating the damping adjuster 80, the damping adjuster 80 moves axially along the insertion shaft 50 through the threaded structure, thereby driving the damping element 70 to move axially along the insertion shaft 50, so as to adjust the extrusion deformation of the damping element 70 in the radial direction of the insertion shaft 50, thereby adjusting the rotational friction resistance provided to the inner surface of the bushing 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 the user with a better user experience.

[0096] Please see Figure 14 and Figure 20 In some embodiments, the insert shaft 50 and the bushing 40 are fixed relative to each other after insertion. The first connecting assembly 10 is provided with a first base 11 fixed to one of the insert shaft 50 and the bushing 40, and the second connecting assembly 20 is provided with a second base 21 rotatably engaged with the other of the insert shaft 50 and the bushing 40. The damping member 70 is connected to the second base 21 and provides rotational damping to the insert shaft 50 or the bushing 40 rotatably engaged with the second base 21, or is connected to the insert shaft 50 or the bushing 40 rotatably engaged with the second base 21 and provides rotational damping to the second base 21.

[0097] One embodiment is provided, such as Figure 14 As shown, the first connecting assembly 10 has a first base 11 fixed to the insert shaft 50, and the second connecting assembly 20 has a second base 21 rotatably engaged with the bushing 40. A damping element 70 is connected to the second base 21 and provides rotational damping to the bushing 40, which rotatably engages with the second base 21. The second base 21 has an insertion hole rotatably engaged with the bushing 40. The damping element 70 can be accommodated within the insertion hole of the second base 21 and connected to the inner wall of the insertion hole. The second base 21 also has an adjusting screw hole connected to the insertion hole. A damping adjuster 80 can be disposed in the adjusting screw hole of the second base 21. The damping adjuster 80 is connected to the damping element 70 to adjust the rotational damping provided by the damping element 70 to the outer surface of the bushing 40. Alternatively, the damping element 70 is connected to the bushing 40 and provides rotational damping to the inner wall of the insertion hole of the second base 21. At this time, the damping element 70 can be connected to the outer peripheral side of the bushing 40, and the damping adjuster 80 is connected to the damping element 70 to adjust the rotational damping provided by the damping element 70 to the inner side of the insertion hole of the second base 21.

[0098] One embodiment is provided, such as Figure 20 As shown, the first connecting assembly 10 has a first base 11 fixedly connected to the bushing 40. The bushing 40 and the insert shaft 50 are fixed relative to each other after insertion. The second connecting assembly 20 has a second base 21 rotatably engaged with the insert shaft 50. The damping element 70 is connected to the second base 21 and provides rotational damping to the insert shaft 50 rotatably engaged with the second base 21. The second base 21 has an insertion hole rotatably engaged with the insert shaft 50. The damping element 70 can be accommodated in the insertion hole of the second base 21 and connected to the inner wall of the insertion hole. The second base 21 also has an adjusting screw hole connected to the insertion hole. The damping adjuster 80 can be disposed in the adjusting screw hole of the second base 21. The damping adjuster 80 is connected to the damping element 70 to adjust the rotational damping provided by the damping element 70 to the outer surface of the insert shaft 50. Alternatively, the damping element 70 is connected to the insert shaft 50 and provides rotational damping to the second base 21. At this time, the damping element 70 can be connected to the outer peripheral side of the insertion shaft 50, and the damping adjuster 80 is connected to the damping element 70 to adjust the rotational damping provided by the damping element 70 to the inner side of the insertion hole of the second base 21.

[0099] One embodiment is provided, such as Figure 16 As shown and Figure 18 As shown, the insert shaft 50 and the bushing 40 are fixed relative to each other after being inserted. The first connecting assembly 10 is provided with a first base 11 that is rotatably engaged with one of the insert shaft 50 and the bushing 40, and the second connecting assembly 20 is provided with a second base 21 that is fixed with the other of the insert shaft 50 and the bushing 40. The damping element 70 is connected to the first base 11 and provides rotational damping to the insert shaft 50 or the bushing 40 that is rotatably engaged with the first base 11, or it is connected to the insert shaft 50 or the bushing 40 that is rotatably engaged with the first base 11 and provides rotational damping to the first base 11.

[0100] Specifically, such as Figure 18 As shown, if the first connecting assembly 10 has a first base 11 rotatably engaged with the insertion shaft 50, then the second connecting assembly 20 has a second base 21 fixed to the bushing 40. The damping element 70 is connected to the first base 11 and provides rotational damping to the insertion shaft 50 rotatably engaged with the first base 11. The first base 11 has an insertion hole rotatably engaged with the insertion shaft 50. The damping element 70 can be accommodated in the insertion hole of the first base 11 and connected to the inner wall of the insertion hole. The first base 11 also has an adjusting screw hole connected to the insertion hole. A damping adjuster 80 can be disposed in the adjusting screw hole of the first base 11. The damping adjuster 80 is connected to the damping element 70 to adjust the rotational damping provided by the damping element 70 to the outer surface of the insertion shaft 50. Alternatively, the damping element 70 is connected to the insertion shaft 50 and provides rotational damping to the first base 11. At this time, the damping element 70 can be connected to the outer peripheral side of the insertion shaft 50, and the damping adjuster 80 is connected to the damping element 70 to adjust the rotational damping provided by the damping element 70 to the inner side of the insertion hole of the first base 11.

[0101] like Figure 16 The first connecting assembly 10 has a first base 11 rotatably engaged with the bushing 40, and the second connecting assembly 20 has a second base 21 fixed to the insert shaft 50. A damping element 70 is connected to the first base 11 and provides rotational damping to the bushing 40, which rotatably engages with the first base 11. The first base 11 has an insertion hole rotatably engaged with the bushing 50, and the damping element 70 can be accommodated within the insertion hole of the first base 11 and connected to the inner wall of the insertion hole. The first base 11 also has an adjusting screw hole connected to the insertion hole, and a damping adjuster 80 can be disposed in the adjusting screw hole of the first base 11. The damping adjuster 80 is connected to the damping element 70 to adjust the rotational damping provided by the damping element 70 to the outer surface of the bushing 40. Alternatively, the damping element 70 is connected to the bushing 40 and provides rotational damping to the first base 11. At this time, the damping element 70 can be connected to the outer peripheral side of the bushing 40, and the damping adjuster 80 is connected to the damping element 70 to adjust the rotational damping provided by the damping element 70 to the inner side of the insertion hole of the first base 11.

[0102] Please see Figure 2 In some embodiments, the damping member 70 is provided with a wedge-shaped structure arranged 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 clamping force of the wedge-shaped structure radially along the insertion shaft 50.

[0103] Specifically, the wedge structure can be made of plastic. The wedge structure exerts pressure on the insertion shaft 50 and the first base 11 or second base 21 that rotatably engages with the insertion shaft 50. The deformation of the wedge structure generates a clamping force radially along the insertion shaft 50. The damping adjuster 80 adjusts the clamping force radially along the insertion shaft 50 by adjusting the axial position of the damping element 70, thereby adjusting the rotational damping provided by the damping element 70. For example... Figure 2 In the process, the damping adjuster 80 adjusts the damping element 70 to move upward along the insertion shaft 50, increasing the radial clamping force of the wedge structure along the insertion shaft 50, thereby increasing the rotational damping provided by the damping element 70. Conversely, the damping adjuster 80 adjusts the damping element 70 to move downward along the insertion shaft 50, decreasing the radial clamping force of the wedge structure along the insertion shaft 50, thereby decreasing the rotational damping provided by the damping element 70.

[0104] In some embodiments, the damping element 70 may also be provided with a wedge-shaped structure circumferentially arranged around the bushing 40. The wedge-shaped structure exerts pressure on the bushing 40 and the first base 11 or the second base 21 that rotatably engages with the bushing 40. The deformation of the wedge-shaped structure generates a clamping force along the radial direction of the bushing 40. The damping adjuster 80 adjusts the axial position of the damping element 70 along the bushing 40 to adjust the clamping force of the wedge-shaped structure along the radial direction of the bushing 40, thereby adjusting the rotational damping provided by the damping element 70.

[0105] Please see Figure 2 and Figure 23 In some embodiments, the limiting mechanism 30 is disposed on the bushing 40. Specifically, when the first connecting assembly 10 is provided with the bushing 40, the limiting mechanism 30 is disposed on the bushing 40 of the first connecting assembly 10; when the second connecting assembly 20 is provided with the bushing 40, the limiting mechanism 30 is disposed on the bushing 40 of the second connecting assembly 20 (e.g., Figure 2 (As shown).

[0106] Please combine Figure 24 In some embodiments, the locking assembly 31 has a locking member 311 that slides and extends within the inner wall of the bushing 40, and the insert shaft 50 is provided with a locking groove 43 that cooperates with the locking member 311.

[0107] In some embodiments, the bushing 40 has a side 42 parallel to the pushing direction, and the locking member 311 slides and extends along the direction perpendicular to the side 42 on the inner wall of the bushing 40.

[0108] Specifically, when the insert shaft 50 is inserted into the bushing 40, the locking member 311 on the inner wall of the bushing 40 corresponds to the locking groove 43 on the insert shaft 50. A portion of the locking member 311 can slide from the inner wall of the bushing 40 along a direction perpendicular to the side of the bushing 40 into the locking groove 43, preventing the insert shaft 50 from displacing axially relative to the bushing 40, thus locking the insert shaft 50 and the bushing 40, and consequently locking the first connecting assembly 10 and the second connecting assembly 20. In other embodiments, the locking member 3111 can also slide and extend along the direction parallel to the side 42 or in any other direction within the inner wall of the bushing 40.

[0109] In some embodiments, the end of the insert shaft 50 that extends into the bushing 40 has a first chamfered structure, and the end of the locking member 311 near the insert shaft 50 has a second chamfered structure. When the insert shaft 50 extends into the bushing 40, the first chamfered structure and the second chamfered structure cooperate.

[0110] Specifically, when no insert shaft 50 is inserted into the bushing 40, the locking member 311 protrudes from the inner wall of the bushing 40. When the insert shaft 50 begins to extend into the bushing 40, the locking member 311 contacts the end of the insert shaft 50 that extends into the bushing 40. At this time, the first chamfered structure of the insert shaft 50 engages with the second chamfered structure of the locking member 311, generating an interaction force between the first and second chamfered structures. Since the locking member 311 can slide and extend, it receives the force provided by the first chamfered structure and slides back into the inner wall of the bushing 40. As the insert shaft 50 continues to extend into the bushing 40, the locking member 311 is subjected to the force of the side wall of the insert shaft 50 and remains within the inner wall of the bushing 40. When the insert shaft 50 is fully inserted into the bushing 40, the locking member 311 and the locking groove 43 are in the corresponding positions. The locking member 311 is no longer subjected to force and can automatically slide into the locking groove 43, so that the insert shaft 50 and the bushing 40 are locked, thereby locking the first connecting assembly 10 and the second connecting assembly 20.

[0111] Please see Figure 23 and Figure 24 In some embodiments, the locking assembly 31 further includes a spring 312. The spring 312 is used to provide a restoring force to the locking member 311 to return to the locked position after the first connecting assembly 10 is separated from the second connecting assembly 20.

[0112] Specifically, one end of the spring 312 is connected to the locking member 311, and the other end is connected to the bushing 40. When the insert shaft 50 has not yet been inserted into the bushing 40, the spring 312 is in a pre-compressed state, and the locking member 311 protrudes from the inner wall of the bushing 40. When the insert shaft 50 begins to extend into the bushing 40, an interaction force is generated between the first chamfered structure and the second chamfered structure. The locking member 311 receives the force provided by the first chamfered structure and slides and retracts into the inner wall of the bushing 40, at which time the spring 312 is in a compressed state. As the insert shaft 50 continues to extend into the bushing 40, the locking member 311 is held in place by the force of the side wall of the insert shaft 50, and the spring 312 remains compressed. When the insert shaft 50 is fully inserted into the bushing 40, the locking member 311 and the locking groove 43 are in corresponding positions. When the locking member 311 is no longer subjected to the force of the insert shaft 50, the spring 312 returns to its pre-compressed state, and the locking member 311 slides into the locking groove 43 under the restoring force of the spring 312. At this time, the locking member 311 is in the locked position, locking the insert shaft 50 and the bushing 40. When it is necessary to remove the insert shaft 50 from the bushing 40, the user controls the spring 312 to compress through the operating control unit 321, causing the locking member 311 to slide back into the inner wall of the bushing 40. When the insert shaft 50 and the bushing 40 are completely disassembled, that is, when the first connecting assembly 10 and the second connecting assembly 20 are separated, the spring 312 returns to its pre-compressed state, and the locking member 311 returns to the locked position under the restoring force of the spring 312.

[0113] Please see Figure 3 In some embodiments, the bushing 40 is provided with a shaft hole 44 for detachable insertion of the shaft 50 and an operating portion 41 offset from the shaft hole 44. The unlocking component 32 is at least partially disposed in the operating portion 41 to receive the unlocking operation.

[0114] Specifically, the insertion shaft 50 extending into the bushing 40 refers to the insertion shaft 50 extending into the shaft hole 44 of the bushing 40. The operation unit 41 is a component that allows the user to operate the pusher connecting device 100. The unlocking component 32 is partially or entirely provided in the operation unit 41 to receive the unlocking operation, thereby keeping the locking component 31 in the unlocked state.

[0115] Please see Figure 23 and Figure 25 In some embodiments, the unlocking component 32 includes a control element 321. The control element 321 is connected to the locking component 31 and is used to receive the unlocking force and cause the locking component 31 to be in the unlocked state.

[0116] Specifically, when the insert shaft 50 and the bushing 40 are in the insertion state, the locking component 31 locks the insertion of the first connecting component 10 and the second connecting component 20. When it is necessary to disassemble the first connecting component 10 and the second connecting component 20, the user provides an unlocking force to the control component 321 through the operation unit 41. The control component 321 receives the unlocking force and causes the locking component 31 to release the lock and enter the unlocked state.

[0117] In some embodiments, the control element 321 is movably engaged with the bushing 40, and the locking assembly 31 includes a locking element 311 fixed to the control element 321. The control element 321 can move the locking element 311 to a position that locks with or unlocks the insert shaft 50.

[0118] Please see Figure 3 , Figures 23 to 25 In some embodiments, the bushing 40 has a side 42 parallel to the pushing direction, the locking member 311 is slidably fitted to the bushing 40, and the control member 321 is a pressable member disposed on the side 42.

[0119] Specifically, the pressing member is fixedly connected to the locking member 311. 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 to or unlocked from the insert shaft 50. For example, when it is necessary to remove the insert shaft 50 from the bushing 40, the user can press the pressing member to control the locking member 311 to slide and retract back into the inner wall of the bushing 40, which is the position where the insert shaft 50 is unlocked.

[0120] Please see Figure 26 In some implementations, in Figure 3 Based on the embodiments, an implementation is provided in which the pressing member is replaced with the pulling member 3211, the bushing 40 has a side 42 parallel to the pushing direction, the locking member 311 is slidably fitted to the bushing 40, and the control member 321 is a pulling member 3211 arranged on the side 42 that can be pulled.

[0121] Specifically, the pull member 3211 is located on one side 42 of the bushing 40 near the snap-fit ​​end of the locking member 311. The pull member 3211 can drive the locking member 311 to slide, moving the locking member 311 to a position where it is locked to or unlocked from the insert shaft 50. For example, Figure 26 As shown, the first transmission mechanism 313 connects the pulling member 3211 and the locking member 311. When it is necessary to remove the insert shaft 50 from the bushing 40, the user can pull the pulling member 3211 along the direction perpendicular to the side 42 of the bushing 40. The first transmission mechanism 313 will drive the locking member 311 to slide and retract back into the inner wall of the bushing 40, which is the position to unlock the insert shaft 50.

[0122] Please see Figure 27 In some implementations, in Figure 3Based on the previous embodiment, an implementation is provided in which the pressing element is replaced by a knob 3212, the bushing 40 has a side side parallel to the pushing direction, the locking element 311 is slidably fitted to the bushing 40, and the control element 321 is a knob that is rotatable and disposed on the side side 42.

[0123] Specifically, knob 3212 can cause locking member 31 to slide, moving locking member 311 to a position where it is locked to or unlocked from insert shaft 50. For example... Figure 27 As shown, a second transmission mechanism 314 connects 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 to unlock in a straight line. It can be understood that the locking member 311 can be set to slide to the position where the insert shaft 50 is locked or unlocked when the knob 3212 is rotated in different directions. For example, the locking member 311 can be set to slide to the position where the insert shaft 50 is unlocked when the knob 3212 is rotated clockwise. When it is necessary to remove the insert shaft 50 from the bushing 40, the user can control the locking member 311 to slide back into the inner wall of the bushing 40 by rotating the knob 3212 clockwise, which is the position where the insert shaft 50 is unlocked. Alternatively, when the knob 3212 is rotated counterclockwise, the locking member 311 can be slid to the position where the insert shaft 50 is unlocked. When it is necessary to remove the insert shaft 50 from the bushing 40, the user can control the locking member 311 to slide back into the inner wall of the bushing 40 by rotating the knob 3212 counterclockwise, which is the position where the insert shaft 50 is unlocked.

[0124] Please see Figure 28 In some implementations, in Figure 3 Based on the previous embodiment, an implementation is provided in which the pressing element is replaced by a sliding button 3213. The bushing 40 has a side side parallel to the pushing direction, the locking element 311 is slidably engaged with the bushing 40, and the control element 321 is a sliding button 3213 disposed on the side side 42.

[0125] Specifically, the slide button 3213 can drive the locking member 311 to slide, causing the locking member 311 to move to a position where it is locked to or unlocked from the insertion shaft 50. For example... Figure 28As shown, a third transmission mechanism 315 connects the sliding button 3213 and the locking member 311. 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 and unlocks in a straight line. It can be understood that, for example, when it is necessary to remove the insert shaft 50 from the bushing 40, the user can control the locking member 311 to slide and retract back into the inner wall of the bushing 40 by sliding the sliding button 3213 along the side 42 of the bushing 40, which is the unlocked position of the insert shaft 50.

[0126] Please see Figure 23 and Figure 25 In some embodiments, the unlocking component 32 includes a retainer 322, which is movable to connect with the locking component 31 when the locking component 31 is in the unlocked state, for restricting the movement of the locking component 31 so that the locking component 31 remains in the unlocked state.

[0127] Specifically, when it is necessary to disassemble the first connecting assembly 10 and the second connecting assembly 20, the user provides an unlocking force to the control member 321 through the operation unit 41. The control member 321 receives the unlocking force, causing the locking assembly 31 to release and enter the unlocked state. When the locking assembly 31 enters the unlocked state, it will connect with the retaining member 322. For example, a slot 3221 can be provided on the retaining member 322, and the slot 3221 is located at the end of the retaining member 322 near the locking member 311 (when the insert shaft 50 is inserted into the bushing 40, the retaining member 322 moves until the slot 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 component 31 is released, the boss 3222 slides along with the locking member 311, and can slide into the slot 3221 located on the sliding path of the locking member 311 and engage, thereby connecting the locking component 31 with the retaining member 322, and putting the unlocking component 32 in the unlocked and held state. The retaining member 322 can restrict the movement of the locking component 31, thereby keeping the locking component 31 in the unlocked state, so that the user can detach the second connecting component 20 relative to the first connecting component 10.

[0128] Please see Figure 23 and Figure 25 In some embodiments, the retainer 322 is rotatably connected to the bushing 40. In this case, the unlocking assembly 32 also includes a torsion spring 323, which provides a resetting force to allow the retainer 322 to rotate and release from the locking assembly 31 after the insert shaft 50 is separated from the bushing 40.

[0129] Specifically, the retaining member 322 is rotatably connected to the bushing 40 via a connecting rod 3223 connected to the bushing 40. One end of the connecting rod 3223 is connected to the side of the bushing 40 where the control member 321 is located, and the other end is connected to the side of the bushing 40 opposite to the side where the control member 321 is located. When no insert shaft 50 is inserted, the torsion spring 323 is in a pre-torsion state. When the insert shaft 50 is inserted into the bushing 40, the torsion spring is in a torsion state, providing torsional torque to hold the retaining member 322 against the insert shaft 50. When the insert shaft 50 is released from the bushing 40 but before the insert shaft 50 is disengaged from the bushing 40, the retaining member 322 is connected to the locking assembly 31, and the retaining member 322 can restrict the movement of the locking assembly 31 under the action of torsional torque. After the insert shaft 50 is separated from the bushing 40, the unlocking assembly 32 needs to release the unlocked state of the locking assembly 31, returning to the state when no insert shaft 50 is inserted. The torsion spring 323 returns to its pre-torsion state and deforms, thereby providing a reset force to the retainer 322, causing the end of the retainer 322 that originally abutted the insert shaft 50 to rotate into the shaft hole (which will be described in detail later). The slot 3221 of the retainer 322 rotates in the opposite direction and disengages from the boss 3222 of the locking assembly 31, thereby releasing the retainer 322 from the locking assembly 31 and thus releasing the unlocked state of the locking assembly 31.

[0130] Please see Figure 29 and Figure 30 In some embodiments, the retainer 322 is slidably connected to the bushing 40. In this case, the unlocking assembly 32 may also include a rectangular spring 3225, which provides a resetting force for the retainer 322 to slide and release from the locking assembly 31 after the insert shaft 50 is separated from the bushing 40.

[0131] Specifically, the retaining member 322 includes a sliding member 3224, a rectangular spring 3225, a gear 3226, and a first transmission member 3227. The sliding member 3224 is slidably connected to the bushing 40 and is used to abut against the insertion shaft 50 to sense the insertion of the insertion shaft 50. Under the insertion limiting action of the insertion shaft 50, the sliding member 3224 retracts relative to the inner wall of the shaft hole, and then drives the first transmission member 3227 to move closer to the locking member 311 via the gear 3226, so that the slot 3221 on the first transmission member 3227 engages with the boss 3222 of the locking member 311. The sliding member 3224 and the gear 3226 are engaged by a rack and pinion arranged in a straight line, and the first transmission member 3227 and the gear 3226 are engaged by a rack and pinion arranged in a straight line, so that the sliding member 3224 and the first transmission member 3227 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 insert shaft 50 into the bushing 40, the insert shaft 50 compresses the third chamfered structure of the slider 3224, generating an interaction force that causes the slider 3224 to move. The rectangular spring 3225 is compressed, causing the first transmission member 3227 to move closer to the locking assembly 31. Then, when the locking assembly 31 enters the unlocked state, the first transmission member 3227 can engage with the locking member 311 of the locking assembly 31, keeping the locking assembly 31 in the unlocked state. After the insert shaft 50 separates from the bushing 40, the unlocking assembly 32 needs to release the unlocked state of the locking assembly 31, returning it to the state before the insert shaft 50 was inserted. At this time, the third chamfered structure is no longer subjected to the force of the insert shaft 50, and the rectangular spring 3225 returns to its pre-compressed state, providing a reset force to the inner wall of the slider 3224 extending from the shaft hole. This causes the first transmission member 3227 to slide in the opposite direction, releasing the locking assembly 31 from its positioning, thus releasing the unlocked state of the locking assembly 31.

[0132] Please see Figure 3 and Figure 23 In some embodiments, the bushing 40 is provided with a shaft hole 44 for the insertion of the shaft 50. When the shaft 50 is disengaged from the bushing 40, one end of the retainer 322 extends into the shaft hole 44, and the other end disengages from the locking assembly 31, thereby releasing the positioning of the locking assembly 31.

[0133] Specifically, when the insert shaft 50 is inserted 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 insert shaft 50, keeping its length direction approximately parallel to the insert shaft 50. At this time, for example, the torsion spring 323 is in a deformed state. When the insert shaft 50 is disengaged from the bushing 40, the side wall of the insert shaft 50 is no longer limited to the end of the retaining member 322 away from the locking member 311. The torsion spring 323 returns to its pre-torsional deformed state, providing a reset force to the retaining member 322, causing the end of the retaining member 322 away from the locking member 311 to extend into the shaft hole 44, and the other end to disengage from the locking assembly 31, thus releasing the positioning of the locking assembly 31.

[0134] Please see Figure 2 , Figure 31 and Figure 32 In some embodiments, the limiting mechanism 30 is disposed on the insertion shaft 50. Specifically, when the first connecting component 10 is provided with the insertion shaft 50, the limiting mechanism 30 is disposed on the insertion shaft 50 of the first connecting component 10; when the second connecting component 20 is provided with the insertion shaft 50, the limiting mechanism 30 is disposed on the insertion shaft 50 of the second connecting component 20.

[0135] In some embodiments, the insert shaft 50 has an operating portion 41 located outside the bushing 40, and the unlocking component 32 is at least partially disposed on the operating portion 41 to receive the unlocking operation.

[0136] Specifically, the operation unit 41 is a component that allows the user to operate the thruster connection device 100. The unlocking component 32 is partially or wholly disposed in the operation unit 41 to receive the unlocking operation, thereby keeping the locking component 31 in the unlocked state.

[0137] In some embodiments, the unlocking component 32 includes a control element 321. The control element 321 is mounted on the operating part 41 and connected to the locking component 31, and is used to receive the unlocking force and drive the locking component 31 to the unlocked state.

[0138] Specifically, when the insert shaft 50 and the bushing 40 are in the insertion state, the locking component 31 locks the insertion of the first connecting component 10 and the second connecting component 20. When it is necessary to disassemble the first connecting component 10 and the second connecting component 20, the user provides an unlocking force to the control component 321 through the operation unit 41. The control component 321 receives the unlocking force and causes the locking component 31 to release the lock and enter the unlocked state.

[0139] Understandably, in Figure 23 Based on the previous embodiment, the locking component 31 is slidably disposed on the bushing 40, instead of the locking component 31 being slidably disposed on the insert shaft 50 (e.g. Figure 31 and Figure 32 As shown), the insert shaft 50 is provided with a sliding groove along the vertical axis and an inner cavity with a connecting sliding groove. The base of the insert shaft 50 is provided with a pressing groove connecting the inner cavity. The control member 321 can be pressed and fitted into the pressing groove. The inner cavity is provided with a second transmission member 316 connecting the control member 321 and the locking member 311, so as to transmit the pressing and sliding of the control member 321 to the locking member 311, thereby driving the locking member 311 to retract to the outer wall of the insert shaft 50, and the locking member 311 disengages from the locking groove 43 on the inner wall of the bushing 40.

[0140] In some embodiments, the unlocking component 32 includes a retainer 322 that can move to connect with the locking component 31 when the locking component 31 is in the unlocked state, thereby restricting the movement of the locking component 31 so that the locking component 31 remains in the unlocked state.

[0141] Same as above, Figure 23 and Figure 25 In this embodiment, the retainer 322, which can elastically extend and retract within the inner wall of the bushing 40, can be replaced by one that can elastically extend and retract within the outer wall of the insert shaft 50. Furthermore, the retainer 322 can limit the locking member 311 to maintain the unlocked state, or separate from the locking member 311 to release the locked state.

[0142] Specifically, when it is necessary to disassemble the first connecting assembly 10 and the second connecting assembly 20, the user provides an unlocking force to the control component 321 through the operation unit 41. The control component 321 receives the unlocking force and causes the locking assembly 31 to unlock and enter the unlocked state. When the locking assembly 31 enters the unlocked state, it will connect with the retaining component 322. For example, a slot 3221 can be provided on the retaining component 322. The slot 3221 is located at the end of the retaining component 322 near the locking component 311 (when the insert shaft 50 is inserted into the bushing 40, the retaining component 322 slides and retracts until the slot 3221 is located on the sliding path of the locking component 311). A boss 3222 is provided on the locking component 311. The boss 3222 is located between the latching end of the locking component 311 and the second transmission component 316. When the locking assembly 31 is released, the boss 3222 slides along with the locking member 311, and can slide into the slot 3221 located on the sliding path of the locking member 311 and be fixed, thus realizing the connection between the locking assembly 31 and the retaining member 322, so that the unlocking assembly 32 is in the unlocked and retained state. The retaining member 322 can restrict the movement of the locking assembly 31, thereby keeping the locking assembly 31 in the unlocked state, so that the user can detach the second connecting assembly 20 relative to the first connecting assembly 10.

[0143] In some embodiments, the insert shaft 50 has a mating portion (not shown) located within the bushing 40, the locking assembly 31 has a locking member 311 that is slidably telescopically disposed in the mating portion, and the inner wall of the bushing 40 is provided with a locking groove 43 that can mate with the locking member 311.

[0144] Specifically, when the insert shaft 50 is inserted into the bushing 40, the locking groove 43 on the inner wall of the bushing 40 and the locking member 311 of the insert shaft 50 are positioned correspondingly. A portion of the locking member 311 can slide into the locking groove 43 on the inner wall of the bushing 40 to prevent the insert shaft 50 from displacing axially relative to the bushing 40, thereby locking the insert shaft 50 inside the bushing 40 and preventing it from dislodging from the bushing 40 due to vibration or warping.

[0145] In some embodiments, the locking assembly 31 further includes a spring 312. The spring 312 provides a restoring force to the locking member to return to the locked position after the first connecting assembly 10 is separated from the second connecting assembly 20.

[0146] Specifically, such as Figure 32 As shown, one end of the spring 312 is connected to the control component 321, and the other end is connected to the second transmission component 316. When the insert shaft 50 has not yet extended into the bushing 40, the spring 312 is in a pre-compressed state, and the locking member 311 protrudes from the outer wall of the insert shaft 50. When the insert shaft 50 begins to extend into the bushing 40, the locking member 311 receives the force provided by the bushing 40 and slides and retracts into the inner wall of the mating part, at which time the spring 312 is in a compressed state. As the insert shaft 50 continues to extend into the bushing 40, the locking member 311 is held in the inner wall of the mating part by the force of the side wall of the bushing 40, at which time the spring 312 remains in a compressed state. When the insert shaft 50 is fully inserted into the bushing 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 of the bushing 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 time, the locking member 311 is in the locked position, locking the insert shaft 50 to the bushing 40. When it is necessary to remove the insert shaft 50 from the bushing 40, the user controls the spring 312 to compress by operating the control unit 321, causing the locking member 311 to slide back into the inner wall of the mating part.

[0147] Please see Figure 33 In some embodiments, one end of the bushing 40 is open for insertion of the insert shaft 50, and the other end of the bushing 40 is closed to limit the insertion of the insert shaft 50. The bushing 40 has a vent hole 45 at the closed end for venting air trapped between the insert shaft 50 and the bushing 40.

[0148] Specifically, when the insert shaft 50 is inserted into the bushing 40, the insert shaft 50 extends from the open end of the bushing 40 until it reaches the closed end of the bushing 40 used for limiting. During the insertion process, due to the tolerance fit between the insert shaft 50 and the bushing 40, the air originally in the bushing 40 is pushed to the closed end of the bushing 40, becoming trapped air. This trapped air creates resistance to the insert shaft 50, requiring the user to exert more force to complete the insertion. A vent hole 45 is provided at the closed end of the bushing 40. During the insertion of the insert shaft 50 into the bushing 40, the trapped air is discharged from the vent hole 45, thus allowing the user to more easily complete the insertion of the insert shaft 50 and the bushing 40.

[0149] Please see Figure 34 In some embodiments, the bushing 40 is provided with a water inlet 46. The water inlet 46 is used to allow liquid to enter the bushing 40 when the insert shaft 50 is inserted into the bushing 40.

[0150] Specifically, in practical applications, the water-based mobile device 1000 of this application is prone to the entry of sand, salt, or other particulate matter into the bushing 40, causing the insert shaft 50 to jam against the bushing 40, preventing rotation or disassembly. Therefore, it is necessary to clean the particulate matter from the bushing 40 promptly. A water inlet 46 is provided on the bushing 40. When the insert shaft 50 is inserted into the bushing 40, liquid is injected into the bushing 40 through the water inlet 46, flushing out the particulate matter without disassembling the insert shaft 50 from the bushing 40. In this way, when sand or salt gets stuck in the propeller connecting device 100, the insert shaft 50 and bushing 40 can be effectively prevented from jamming, ensuring the normal functioning of the propeller 300 and providing a better user experience.

[0151] In some embodiments, the bushing 40 includes a sidewall surrounding the insert shaft 50, and a water inlet 46 is disposed on the sidewall. Specifically, the water inlet 46 may be disposed at the middle position of the sidewall, corresponding to the middle position of the insert shaft 50 along the axial direction, so as to facilitate flushing particulate matter out of the bushing 40.

[0152] Please see Figure 35 In some embodiments, the first connecting component 10 is provided with one of the sleeve 93 or the insert 94, and the second connecting component 20 is provided with the other of the sleeve 93 or the insert 94.

[0153] Specifically, the first connecting component 10 may be provided with a retainer 93, and correspondingly, the second connecting component 20 may be provided with a insert plate 94. Alternatively, the first connecting component 10 may be provided with an insert plate 94, and correspondingly, the second connecting component 20 may be provided with a retainer 93 (e.g., Figure 35 (As shown). The first connecting component 10 and the second connecting component 20 are connected by inserting the sleeve 93 and the insert plate 94.

[0154] In some embodiments, the limiting mechanism 30 is disposed on the sleeve 93. Specifically, when the first connecting component 10 is provided with the sleeve 93, the limiting mechanism 30 is disposed on the sleeve 93 of the first connecting component 10; when the second connecting component 20 is provided with the sleeve 93, the limiting mechanism 30 is disposed on the sleeve 93 of the second connecting component 20.

[0155] In some embodiments, the locking assembly 31 has a locking member 311 that slides and extends within the inner wall of the sleeve 93, and the insert plate 94 is provided with a locking groove 43 that mates with the locking member 311.

[0156] 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 inserted into the sleeve 93, the locking member 311 on the inner wall of the sleeve 93 corresponds to the locking groove 43 on the insert plate 94. A portion of the locking member 311 can slide from the inner wall of the sleeve 93 into the locking groove 43, locking the insert plate 94 and the sleeve 93, thereby locking the first connecting assembly 10 and the second connecting assembly 20. When it is necessary to disassemble the insert plate 94 and the sleeve 93, the locking assembly 31 can slide back from the locking groove 43 to the inner wall of the sleeve 93, releasing the locking of the insert plate 94 and the sleeve 93, thereby releasing the locking of the first connecting assembly 10 and the second connecting assembly 20.

[0157] In some embodiments, the sleeve 93 has a shaft hole 44 for detachable insertion of the insert plate 94 and an operating portion 41 offset from the shaft hole 44. The unlocking component 32 is at least partially disposed in the operating portion 41 to receive the unlocking operation.

[0158] Specifically, the insertion of the insert plate 94 and the sleeve 93 refers to the insertion of the insert plate 94 and the sleeve 93 into the shaft hole 44. The operation unit 41 is a component that allows the user to operate the pusher connecting device 100. The unlocking component 32 is partially or entirely disposed in the operation unit 41 to receive the unlocking operation, thereby keeping the locking component 31 in the unlocked state.

[0159] In some embodiments, the locking assembly 31 has a locking member 311 that is 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.

[0160] Specifically, when the insert plate 94 is inserted into the sleeve 93, the locking member 311 on the inner wall of the sleeve 93 corresponds to the locking groove 43 on the insert plate 94. A portion of the locking member 311 can slide along the inner wall of the sleeve 93 into the locking groove 43 to prevent the insert plate 94 from shifting relative to the sleeve 93, thus locking the insert plate 94 and the sleeve 93, and consequently locking the first connecting assembly 10 and the second connecting assembly 20. When it is necessary to disassemble the insert plate 94 and the sleeve 93, the locking member 31 can slide along the inner wall of the sleeve 93 to a position where it disengages from the locking groove 43, releasing the locking of the insert plate 94 and the sleeve 93, and consequently releasing the locking of the first connecting assembly 10 and the second connecting assembly 20.

[0161] In some embodiments, the limiting mechanism 30 is disposed on the insert plate 94. Specifically, when the first connecting component 10 is provided with the insert plate 94, the limiting mechanism 30 is disposed on the insert plate 94 of the first connecting component 10; when the second connecting component 20 is provided with the insert plate 94, the limiting mechanism 30 is disposed on the insert plate 94 of the second connecting component 20.

[0162] In some embodiments, the insert plate 94 has an operation section 41 located outside the card sleeve 93, and the unlocking component 32 is at least partially disposed on the operation section 41 to receive the unlocking operation.

[0163] Specifically, the operation unit 41 is a component that allows the user to operate the thruster connection device 100. The unlocking component 32 is partially or wholly disposed in the operation unit 41 to receive the unlocking operation, thereby keeping the locking component 31 in the unlocked state.

[0164] In some embodiments, the insert plate 94 has a mating portion (not shown) located within the sleeve 93, the locking assembly 31 has a locking member 311 that is slidably telescopically disposed in the mating portion, and the inner wall of the sleeve 93 is provided with a locking groove 43 that can mate with the locking member 311.

[0165] Specifically, when the insert plate 94 is not yet inserted into the sleeve 93, the locking member 311 protrudes from the outer wall of the insert plate 94. As the insert plate 94 begins to insert into the sleeve 93, the locking member 311 receives the force provided by the sleeve 93 and slides back into the inner wall of the mating part. As the insert plate 94 continues to insert into the sleeve 93, the locking member 311 is held in place by the force of the side wall of the sleeve 93. When the insert plate 94 is fully inserted into the sleeve 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 sleeve 93, and part of the locking member 311 slides into the locking groove 43 to prevent the insert plate 94 from displacing relative to the sleeve 93. At this time, the locking member 311 is in the locked position, locking the insert plate 94 and the sleeve 93.

[0166] In some embodiments, the first connecting component 10 or the second connecting component 20 is provided with a lifting shaft 92, which is spaced apart from the sleeve 93 or the insert plate 94.

[0167] In some embodiments, the first connecting component 10 or the second connecting component 20 is provided with a steering shaft 90, which is spaced apart from the ferrule 93 or the insert plate 94.

[0168] Specifically, in this embodiment, the first connecting component 10 and the second connecting component 20 are inserted into the insert plate 94 and the retaining sleeve 93, and are relatively fixed after insertion, without relative rotation. Therefore, the first connecting component 10 or the second connecting component 20 may also be provided with a lifting shaft 92 or a steering shaft 91. For example, as Figure 35As shown, the first connecting assembly 10 is provided with a tilting shaft 92, and the second connecting assembly 20 is provided with a steering shaft 91. The first connecting assembly 10 includes a clamping member 12 and a first steering connector 131. The clamping member 12 is used to install and fix it on the water carrier 1001. The first steering connector 131 is rotatably connected to the clamping member 12 via the tilting shaft 92. The second connecting assembly 20 can tilt relative to the first connecting assembly 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 device 200. The second base 21 is rotatably connected to the second steering connector 132 via the steering shaft 91 to enable the propulsion power device 200 to be steered. The second base 21 is detachably connected to the first steering connector 131 via an insert plate 94.

[0169] Or, such as Figure 36 As shown, 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 used to be installed and fixed on the water carrier 1001, and 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 power unit 200, and the second base 21 is rotatably connected to the second steering connector 132 via the tilting shaft 92 to achieve tilting of the propulsion power unit 200. The second base 21 is detachably connected to the first steering connector 131 via a plate 94. The tilting shaft 92 is used to tilt the propeller 300 up and down to adapt to different water conditions and to avoid corrosion and collision of the underwater parts of the outboard motor. The steering shaft 90 is used to turn the thruster 300 left and right to adjust its course. Thus, the tilting and turning of the thruster 300 can be achieved through the tilting shaft 92 and the steering shaft 90, thereby enabling the tilting and turning of the water-based mobile device 1000. Of course, in other embodiments, the first connecting assembly 10 may also be provided with both the tilting shaft 92 and the steering shaft 91, or the second connecting assembly 20 may also be provided with both the tilting shaft 92 and the steering shaft 91; this is not a limitation.

[0170] In some embodiments, the unlocking component 32 includes a retainer 322. The retainer 322 is configured to connect with the locking component 31 in the unlocked state when the first connecting component 10 and the second connecting component 20 are plugged in, so as to position the locking component 31.

[0171] Specifically, when it is necessary to disassemble the first connecting component 10 and the second connecting component 20, the user controls the locking component 31 to unlock and enter the unlocked state through the unlocking component 32. When the locking component 31 enters the unlocked state, it will connect with the retaining member 322. For example, a slot 3221 can be provided on the retaining member 322, and the slot 3221 is located at the end of the retaining member 322 near the locking member 311 (when the insert plate 94 is inserted into the sleeve 93, the retaining member 322 moves until the slot 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 latching end of the locking member 311. When the locking component 31 is released, the boss 3222 slides along with the locking member 311, and can slide into the slot 3221 located on the sliding path of the locking member 311 and be fixed, thus realizing the connection between the locking component 31 and the retaining member 322, and putting the unlocking component 32 in the unlocked and retained state. The retaining member 322 can position the locking component 31 and restrict the movement of the locking component 31, thereby keeping the locking component 31 in the unlocked state, so that the user can detach the second connecting component 20 relative to the first connecting component 10.

[0172] In some embodiments, the unlocking component 32 further includes a control element 321. The control element 321 is connected to the locking component 31 and is used to receive the unlocking force and cause the locking component 31 to be in the unlocked state.

[0173] Specifically, when the insert plate 94 and the card sleeve 93 are in the inserted state, the locking component 31 locks the insertion of the first connecting component 10 and the second connecting component 20. When it is necessary to disassemble the first connecting component 10 and the second connecting component 20, the user provides an unlocking force to the control component 321 through the operation unit 41. The control component 321 receives the unlocking force and causes the locking component 31 to release the lock and enter the unlocked state.

[0174] In some embodiments, the control member 321 is movably engaged with the sleeve 93, and the locking assembly 31 includes a locking member 311 fixed to the control member 321. The control member 321 can move the locking member 311 to a position that locks or unlocks the insert plate 94.

[0175] Specifically, the ferrule 93 has a side 42 parallel to the pushing direction, and the locking member 311 slides in the ferrule 93 along the direction perpendicular to the side. The control member 321 can be a pressable member, a pullable member, a rotatable knob, or a slide knob disposed on the side 42. For example, the user can control the locking member 311 to move back into the ferrule 93 by pressing the pressable member, that is, to unlock the insert plate 94.

[0176] It should be noted that the explanations of the above embodiments regarding the scheme and related components (such as locking component 31 and unlocking component 32) of "the first connecting component 10 is provided with one of the bushing 40 or the insert 50, and the second connecting component 20 is provided with the other of the bushing 40 or the insert 50" also apply to the scheme and related components (such as locking component 31 and unlocking component 32) of this embodiment of "the first connecting component 10 is provided with one of the card sleeve 93 or the insert plate 94, and the second connecting component 20 is provided with the other of the card sleeve 93 or the insert plate 94". The difference is that the first connecting component 10 and the second connecting component 20 are relatively fixed after being inserted into the card sleeve 93 through the insert plate 94, and will not rotate relative to each other.

[0177] Please see Figure 2 and Figure 37 This application provides a thruster 300, which includes a thruster connecting device 100 and a propulsion power device 200 as described in any of the above embodiments, and a second connecting component 20 is connected to the propulsion power device 200.

[0178] 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 to provide propulsion force. The propeller connection device 100 can be steered to change the direction of the propeller's propulsion force.

[0179] Please see Figure 2 and Figure 37 This application provides a water-based mobile device 1000, which includes a thruster 300 and a water-based carrier 1001, with a first connecting component 10 connected to the water-based carrier 1001.

[0180] Specifically, the water-mobile device 1000 can be various water transportation vehicles such as commercial ships, passenger ships, yachts, fishing boats, sailboats, and civilian vessels; it can also be equipment capable of moving in water, such as water patrol equipment, water management equipment, and water environment monitoring equipment; or it can be equipment such as underwater robots used for underwater operations, etc., without any limitations. The water carrier 1001 is, for example, a ship hull. The water carrier 1001 can provide a certain amount of buoyancy, enabling the water-mobile device 1000 to float on the water surface and carry people, goods, or other carried objects. The thruster 300 is connected to the water carrier 1001 and is used to provide propulsion to push the water carrier 1001 to tilt or turn, etc.

[0181] In summary, the thruster connecting device 100, thruster 300, and water-based mobile device 1000 of this application embodiment, when the first connecting component 10 and the second connecting component 20 are inserted, the locking component 31 of the limiting mechanism 30 is used to lock the insertion of the first connecting component 10 and the second connecting component 20. When the first connecting component 10 and the second connecting component 20 are disassembled, the locking component 31 is released, and the unlocking component 32 of the limiting mechanism 30 is in an unlocked holding state, keeping the locking component 31 in an unlocked state. When the unlocking component 32 is in the unlocked holding state, the second connecting component 20 can receive a disassembly force relative to the first connecting component 10 for disassembly. In this way, the thruster connecting device 100 can be disassembled conveniently and quickly, while ensuring that the thruster connecting device 100 remains stable and does not shake after installation. In addition, the thruster 300 can be stored in a smaller, more compact size, occupying less space.
