[0041] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0042] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present application, rather than all of the embodiments.

[0043] The current outboard motor, that is, the main body of the water propulsion device, is connected to the ship by a clamping assembly, and the outboard motor can turn relative to the clamping assembly to achieve the outboard motor relative to the ship body. In the related art, because the outboard motor is free to rotate relative to the clamping assembly, the operator manually controls the direction of the outboard motor relative to the ship to control the forward movement and steering of the ship body, which is laborious and difficult to control manually.

[0044] Based on this, the embodiment of the present application provides a connection device, and the operator no longer needs to manually control the outboard motor to control the forward movement of the boat. The following is a detailed description of the connection device through a specific embodiment:

[0045] Reference Figures 1 to 15As shown, this embodiment provides a connection device, including a clamping assembly 1 and a connecting assembly 2, wherein the clamping assembly 1 is used to connect with a water body carrier 10, and the clamping assembly 1 is clamped and connected with the water body carrier 10 by a clamp, and the water body carrier 10 is a ship body. The connecting assembly 2 is rotatably connected with the clamping assembly 1, and the connecting assembly 2 can rotate axially in a first direction relative to the clamping assembly 1, and the first direction is usually a direction perpendicular to the transverse direction of the ship, and a mounting position 8 is provided on the connecting assembly 2, and the mounting position 8 is used to connect the main body of the water body propeller 9, and the main body of the water body propeller 9 is used to output propulsion power. The water body propeller 9 is an outboard motor. The main body of the water body propeller 9 includes a main shaft and an underwater power module fixed to the end of the main shaft, and the length direction of the main shaft is parallel to the first direction. The side wall of the main shaft is connected to the connecting assembly 2. The cross section of the main shaft is roughly in the shape of a water drop fluid to reduce the resistance of the main shaft in the water. The power module is provided with a motor and a propeller connected to the motor. By using the power module in which the motor is set underwater, the ambient water can be used to quickly cool the motor and improve the motor efficiency. The motor drives the propeller to rotate, thereby outputting propulsion. The power module can also be provided with a drive circuit board of the electrical connector motor to facilitate rapid cooling of the drive circuit board. The power module can also be provided with a reducer between the motor and the propeller to improve the transmission efficiency between the motor and the propeller. A cavity for accommodating an energy storage unit can be provided in the main shaft, and the energy storage unit can provide electrical energy to the motor, so that the water area propeller no longer needs to obtain electrical energy from the energy storage device on the water area carrier through cables. The cross-section of the main shaft of the water area propeller of the present application is in the shape of a water droplet fluid, so that the main shaft forms a rudder, so that the water area propeller can better obtain steering power.

[0046] Among them, Figures 1 to 4 As shown, the clamping assembly 1 is provided with a limit groove 11, and the connecting assembly 2 is provided with a limit member 21, which forms a movable match with the connecting assembly 2, and the limit member 21 moves along the second direction to insert / disengage the limit groove 11, and the second direction intersects with the first direction, and the second direction is generally the direction in which the main body of the parallel water thruster 9 outputs the propulsion power. The limit member 21 is inserted into the limit groove 11 to lock the main body output propulsion force direction of the water thruster 9 to be parallel to the longitudinal direction of the water carrier 10, and the water carrier 10 moves along the direction of the propulsion force of the water thruster 9. Preferably, the first direction and the second direction intersect perpendicularly.

[0047] In the related art, the connection component 2 drives the water propeller 9 to steer by manually driving the steering rudder. During this process, it is necessary to always hold the steering rudder (for example, hold the tiller handle) and continuously apply force. Most of the time, the water vehicle 10 maintains longitudinal straight driving, and basically no steering is required. However, in this case, in order to prevent the rudder from turning by itself due to the action of the water flow, it is necessary to always apply force to hold the steering rudder. Firstly, it is easy to cause driving fatigue, and secondly, the driver cannot operate the driving with both hands. The connection device provided in the embodiment of the present application is that when the water area carrier 10 is moving forward, the direction of the limit groove 11 is parallel to the longitudinal direction of the water area carrier 10, and the limit piece 21 on the connection component 2 is extended and inserted into the limit groove 11 on the clamping component 1 to limit the turning rotation of the connection component 2 relative to the clamping component 1, so that the rotation of the connection component 2 relative to the clamping component 1 in the turning direction is locked, and the connection component 2 and the clamping component 1 remain in a relatively static state, that is, the main body of the water area propeller 9 and the clamping component 1 remain in a relatively static state in the turning direction, and the rotation of the main body of the water area propeller 9 is locked. At this time, the water area carrier 10 moves forward in a preset direction (the longitudinal direction of the water area carrier 10). After the limit piece 21 is inserted into the limit groove 11, the propulsion direction of the water area propeller 9 can be locked to be parallel to the longitudinal direction of the water area carrier 10, so that the driver can cancel the control of the steering rudder, saving effort, and freeing both hands to perform other driving operations. The forward direction of the water area carrier 10 is easy to control and the controlled forward direction is stable.

[0048] In some embodiments, the clamping assembly 1 includes a fixing member 13 and a rotating member 14. The fixing member 13 is connected to the water body 10. The fixing member 13 includes a clamp. The fixing member 13 clamps the water body 10 through the clamp, for example, the clamp clamps the tail of the hull. The rotating member 14 is rotatably connected to the fixing member 13 through a connecting shaft 15 to drive the main body of the water propeller 9 to tilt relative to the fixing member 13. The connecting shaft 15 is usually arranged horizontally. The limit groove 11 is arranged on the rotating member 14 to limit the turning and rotation of the connecting assembly 2. Figure 5 As shown, in a specific implementation, the rotating member 14 is provided with a rotating shaft 12, and the axial direction of the rotating shaft 12 is the first direction. The connecting component 2 is detachably plugged into the rotating shaft 12. The detachable connecting component 2 and the rotating shaft 12 refers to quick disassembly without the aid of tools. The connecting component 2 is plugged into and matched with the rotating shaft 12 along the axial direction of the rotating shaft 12. When the connecting component 2 is plugged into the rotating shaft 2, the connecting component 2 can rotate relative to the rotating member 14 around the axis of the rotating shaft 12. In some embodiments, when the connecting component 2 is plugged into the rotating shaft 12, the connecting component 2 and the rotating shaft 12 remain fixed, and the rotating shaft 12 can rotate relative to the rotating member 14. In other embodiments, the rotating shaft 12 is fixed to the rotating member 14, and when the connecting component 2 is plugged into the rotating shaft 12, the connecting component 2 and the rotating shaft 12 rotate and cooperate.

[0049] In some embodiments, Figure 5 , Figure 6 , Fig.12 and Fig.13 As shown, the connection assembly 2 and the clamping assembly 1 can be detachably connected along the first direction. Specifically, a first hole 20 is formed on the connection assembly 2 to be pluggable and connected to the rotating shaft 12. The connection assembly 2 is subjected to an external force in the first direction to move away from the clamping assembly 1 so as to pull the rotating shaft 12 out of the first hole 20 to achieve the detachable connection between the connection assembly 2 and the clamping assembly 1.

[0050] In some embodiments, Figures 2 to 4 As shown, the connection assembly 2 is provided with a positioning structure 221, and the positioning structure 221 positions the limiting member 21 to position the limiting member 21 in the first locking state and the second locking state. Figure 2 The middle limiting member 21 is positioned in the first locking state. The first locking state is: the limiting member 21 extends forward to be inserted into the limiting groove 11. Figure 8 The middle limit member 21 is positioned in the second locking state, and the second locking state is: the limit member 21 retreats to disengage from the limit slot 11. When the connection component 2 rotates to the target position relative to the clamping component 1, the target position is that the direction of the limit slot 11 is parallel to the longitudinal direction of the water area carrier 10, and the limit member 21 is inserted into the limit slot 11 to limit the rotation of the connection component 2 relative to the clamping component 1. At this time, the positioning structure 221 positions the limit member 21 so that the limit member 21 remains inserted into the limit slot 11. When the connection component 2 needs to rotate relative to the clamping component 1 to meet the adaptation of the water area carrier 10 to the new working condition, the limit member 21 disengages from the limit slot 11. At this time, the positioning structure 221 positions the limit member 21 so that the limit member 21 remains disengaged from the limit slot 11.

[0051] In some embodiments, Figures 2 to 4 As shown, a slide groove 22 is formed on the connecting assembly 2, and the limiting member 21 includes a sliding portion 211 and a limiting portion 212 connected to each other, the sliding portion 211 and the slide groove 22 form a sliding fit, and a positioning structure 221 is disposed in the slide groove 22 to position the sliding portion 211. The sliding portion 211 slides in the slide groove 22 to drive the limiting portion 212 to insert into the limiting groove 11 or to disengage from the limiting groove 11.

[0052] In some embodiments, the sliding portion 211 is provided with a locking portion 2112 on at least one side along the width direction of the slide slot 22, and the positioning structure 221 is provided with a first recess 2211 and a second recess 2212 arranged at intervals along the length direction of the slide slot 22 on the side wall thereof, and the second recess 2212 is farther from the limiting groove 11 than the first recess 2211, and when the limiting member 21 is in the first locking state, the limiting portion 212 is inserted into the limiting groove 11, and at this time the locking portion 2112 is locked in the first recess 2211. When the limiting member 21 is in the second locking state, the limiting portion 212 is disengaged from the limiting groove 11, and at this time the locking portion 2112 is locked in the second recess 2212.

[0053] In some embodiments, Figure 2 As shown, the sliding portion 211 includes a main body, and the locking portion 2112 is an elastic block 2111 integrally formed with the main body. The elastic block 2111 includes a convex portion that can be locked in the first recess 2211. The end of the elastic block 2111 away from the convex portion is connected to the main body, and a gap is formed between the convex portion and the main body, so that the convex portion can move toward the main body when squeezed by the inner wall of the groove. When the sliding portion 211 slides to the corresponding position of the convex portion and the first recess 2211, the convex portion moves away from the main body into the recess to form a concave-convex fit with the recess, thereby realizing the positioning of the sliding portion 211, and also realizing the positioning of the limiting portion 212 in the first locking state. The first recess 2211 and the second recess 2212 are arc-shaped recesses. When the sliding portion 211 is pushed in the second direction, the convex portion disengages from the first recess 2211. When the sliding portion 211 slides in the slide groove 22 to a position corresponding to the convex portion and the second recess 2212, the convex portion and the second recess 2212 form a concave-convex fit to achieve the positioning of the sliding portion 211, thereby achieving the positioning of the limiting portion 212 in the second locking state.

[0054] In some embodiments, Fig.10 and Fig.11As shown, the sliding portion 211 is provided with an arc-shaped protrusion 4, the positioning structure 221 is provided with a pressure block fixed to the slide groove 22, the pressure block presses the sliding portion 211, and a positioning protrusion is provided on the side of the pressure block facing the sliding portion 211. When the limit member 21 is in the first locking state, the positioning protrusion is located on the side of the arc-shaped protrusion 4 away from the limiting portion 212. When the limit member 21 is in the second locking state, the positioning protrusion is located on the side of the arc-shaped protrusion 4 close to the limiting portion 212. That is to say, the sliding part 211 slides in the slide groove 22 along the second direction under the thrust, and the arc-shaped protrusion 4 can be a bent plate, which forms an integral structure with the limiting part 212. The bent plate bends toward the pressing block protrusion, and the positioning protrusion on the pressing block protrudes toward the sliding part 211. The arc-shaped protrusion 4 and the positioning protrusion are arranged opposite to each other, and the positioning protrusion abuts against the sliding part 211 and is located on the side of the arc-shaped protrusion 4 away from the limiting part 212. The positioning protrusion limits the movement of the sliding part 211 away from the limiting part 212, thereby realizing the positioning of the sliding part 211 by the pressing block, and also realizing the positioning of the limiting part 212 in the first locking state. A gap is locally formed on the side of the bending plate away from the pressure block. When the sliding part 211 is pushed and moves in the slide groove 22, the arc-shaped protrusion 4 is deformed by the pressure of the pressure block. In other words, the bending plate is deformed by the pressure and the gap is squeezed and reduced. When the sliding part 211 moves to the positioning protrusion and is pressed on the arc-shaped protrusion 4, the gap is squeezed so that the bending plate fits the bottom of the slide groove 22 until the sliding part 211 moves to the side where the positioning protrusion is located on the side of the arc-shaped protrusion 4 away from the limiting part 212. The bending plate is not squeezed by the arc-shaped protrusion 4 and returns to the curved shape. The positioning protrusion is located on the side of the arc-shaped protrusion 4 away from the limiting part 212, so that the sliding part 211 cannot move toward the limiting part 212 when not subject to thrust, so as to realize the positioning of the sliding part 211 by the pressure block, and also realize the positioning of the limiting part 212 in the second locking state.

[0055] In some embodiments, Fig.11 As shown, the sliding part 211 is provided with an elongated through hole 41, and the connecting assembly 2 is provided with a guide column 223 for fixing and connecting the pressing block, the guide column 223 is connected to the bottom of the slide groove 22, and the guide column 223 is matched with the elongated through hole 41. The guide column 223 and the elongated through hole 41 are matched with each other in a clearance manner, and do not hinder the sliding part 211 from sliding relative to the slide groove 22. The pressing block is fixedly connected to the connecting assembly 2 through the guide column 223.

[0056] In some embodiments, a push portion 23 is disposed on the sliding portion 211 , and the push portion 23 protrudes from the slide groove 22 , so that an operator can push the push portion 23 to make the sliding portion 211 slide in the slide groove 22 .

[0057] In some embodiments, Figure 2 and Fig. 9As shown, the part of the stopper 21 that cooperates with the stopper groove 11 can rotate relative to the connection component 2 around a third direction, and the third direction is perpendicular to the first direction and the second direction. When the stopper 21 and the stopper groove 11 are installed in a misaligned manner, the stopper 21 is retracted and rotated relative to the connection component 2 around the third direction to release the misaligned impact force of the clamping component 1 on the stopper 21. As shown in the figure, when the stopper 21 and the stopper groove 11 are installed in a misaligned manner, the part of the stopper 21 that cooperates with the stopper groove 11 rotates counterclockwise around the third direction after the stopper 21 touches the clamping component 1 under force to release the misaligned impact force of the clamping component 1 on the stopper 21, so as to prevent the stopper 21 from being damaged by the impact. In specific implementation, the stopper 21 can be hinged to the connection component 2.

[0058] In some embodiments, Figure 2 and Fig. 9 As shown, the connection component 2 is provided with a stop ring 3, and the stop ring 3 is provided with an opening, the opening of which is smaller than the outer diameter of the stop member 21. When the stop member 21 rotates and retracts relative to the connection component 2, the portion of the stop member 21 that cooperates with the stop groove 11 is separated from the stop ring 3 from the opening. When the stop member 21 and the stop groove 11 are installed without misalignment, the stop member 21 passes through the stop ring 3 and then is inserted into the stop groove 11. The opening of the stop ring 3 is smaller than the outer diameter of the stop member 21, and the stop ring 3 restricts the stop member 21 from retracting and rotating relative to the connection component 2 about the third direction.

[0059] Another embodiment of the present application provides a water area propeller 9, such as Fig.14 As shown, it includes a main body and the above-mentioned connecting device, and the main body is connected to the installation position 8.

[0060] Another embodiment of the present application provides a movable device in water area, such as Fig.15 As shown, the water area propeller 9 and the water area carrier 10 are included, and the clamping assembly 1 is clamped on the water area carrier 10. When the water area carrier 10 is adjusted to move forward in the right direction, the limiting member 21 on the connecting device carrying the water area propeller 9 is inserted into the limiting groove 11 of the clamping assembly 1, and the operator does not need to hold the connecting assembly 2 to prevent the connecting assembly 2 from rotating relative to the water area carrier 10, which saves manpower, and the forward direction of the water area carrier 10 is easy to control and the controlled forward direction is stable.
