[0027] In order to more clearly understand the above-mentioned objectives, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application can also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present application, not all of the embodiments.

[0029] Current outboard motors (watercraft) are connected to the boat using a clamping assembly, which allows the outboard motor to steer relative to the boat. In the prior art, because the outboard motor's clamping assembly rotates freely relative to the boat, the operator manually controls the outboard motor's direction relative to the boat to control its propulsion and steering. This is laborious and difficult to control manually.

[0030] Based on this, the embodiment of the present application provides a connection device, which eliminates the need for the operator 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:

[0031] Reference Figures 1 to 6 As shown, this embodiment provides a connecting device, including a clamping assembly 1, an intermediate shaft 3 and a connecting assembly 2. The connecting assembly 2 is used to connect to the main body of the water propulsion device 100. The clamping assembly 1 is clamped on the water carrier 200. The intermediate shaft 3 is rotatably connected to the clamping assembly 1. The connecting assembly 2 is detachably connected to the intermediate shaft 3. The connecting assembly 2 can be installed on the intermediate shaft 3 along the axial direction of the intermediate shaft 3 and fixed to the intermediate shaft 3. The connecting assembly 2 can rotate relative to the clamping assembly 1 through the intermediate shaft 3. In other words, the main body of the water propulsion device 100 can rotate relative to the water carrier 200.

[0032] The clamping assembly 1 is provided with a limit pin 4, which is movably engaged with the clamping assembly 1 and can be inserted into the intermediate shaft 3 to limit the rotation of the connecting assembly 2 relative to the clamping assembly 1. When the main body of the water propeller 100 is rotated to a suitable position relative to the water carrier 200, the operator no longer needs to hold the connecting assembly 2 to prevent it from rotating relative to the water carrier 200, saving manpower and making the forward direction of the water carrier 200 easy to control and stable.

[0033] In the embodiment of the present application, the water propulsion device 100 is an outboard motor. Figure 5As shown, the main body of the water propeller 100 includes a main shaft and an underwater power module fixed to the end of the main shaft. The main shaft has a length direction parallel to the first direction. The sidewalls of the main shaft are connected to the connecting assembly 2. The main shaft cross-section is roughly shaped like a water droplet to reduce the main shaft's resistance in water. The power module is equipped with a motor and a propeller connected to the motor. With the motor located in the power module underwater, the motor can be quickly cooled by ambient water, improving motor efficiency. The motor drives the propeller to rotate, thereby outputting propulsion. The power module may also be equipped with an electrical connector for the motor's drive circuit board to facilitate rapid cooling of the drive circuit board. The power module may also be equipped with a speed reducer between the motor and the propeller to improve the transmission efficiency between the motor and the propeller. The main shaft may be provided with a cavity to accommodate an energy storage unit. The energy storage unit can provide electrical energy to the motor, eliminating the need for the water propeller to obtain electrical energy from an energy storage device on the water carrier via cables. The main shaft cross-section of the water propeller of the present application is shaped like a water droplet, forming a rudder, which helps the water propeller better obtain steering power.

[0034] In some embodiments, the clamping assembly 1 is used to connect with the water carrier 200, and the clamping assembly 1 includes a clamp that clamps the tail of the water carrier 200. In this embodiment, the intermediate shaft 3 is rotatably arranged on the clamping assembly 1, and the portion of the intermediate shaft 3 that rotatably cooperates with the clamping assembly 1 is provided with a hole that allows the limiting pin 4 to be inserted. For example, the hole is provided on the circumferential side wall of the intermediate shaft 3, and the extension direction of the hole is perpendicular to the axis of the intermediate shaft 3. The direction in which the limiting pin 4 is inserted into the intermediate shaft 3 is perpendicular to the axis of the intermediate shaft 3. Therefore, after the limiting pin 4 is inserted into the hole of the intermediate shaft 3, a portion of the limiting pin 4 is still on the clamping assembly 1 and cannot rotate around the axis of the intermediate shaft 3, thereby limiting the intermediate shaft 3 from rotating around the axis of the intermediate shaft 3, and the connecting assembly 2 remains fixed relative to the clamping assembly 1 in the direction around the axis of the intermediate shaft 3. When the direction of the propulsion force output by the main body of the water propeller 100 is parallel to the longitudinal direction of the water carrier 200, the limit pin 4 is inserted into the intermediate shaft 3 to form a limit fit to limit the rotation of the connecting assembly 2 relative to the clamping assembly 1, thereby maintaining the driving direction of the water propeller 100 parallel to the longitudinal direction of the water carrier 200. The operator is no longer required to hold the connecting assembly 2 to prevent the connecting assembly 2 from rotating relative to the water carrier 200, saving manpower, and making the forward direction of the water carrier 200 easy to control and stable. It can be understood that the limit pin 4 is inserted into the intermediate shaft 3 so that the intermediate shaft 3 is no longer rotatable on the clamping assembly 1. When the connecting assembly 2 is connected to the intermediate shaft 3, the connecting assembly 2 and the intermediate shaft 3 remain fixed, so that the connecting assembly 2 remains fixed relative to the clamping assembly 1 around the intermediate shaft 3.

[0035] In some embodiments, to enable the limiting pin 4 to be inserted into the intermediate shaft 3 for a limited fit, a first channel 5 is formed on the clamping assembly 1, and a second channel 6 is formed on the intermediate shaft 3. The second channel 6 extends radially along the intermediate shaft 3 and is communicable with the first channel 5. The limiting pin 4 is slidably inserted into the first channel 5 and can extend into the second channel 6 to limit the rotation of the connecting assembly 2 relative to the clamping assembly 1. Processing the first channel 5 on the clamping assembly 1 and forming the second channel 6 on the intermediate shaft 3 is simple and low-cost.

[0036] In some embodiments, an operating cavity 7 is formed within the clamping assembly 1 and communicates with the first channel 5. A pull ring 8 is provided at one end of the limiting pin 4 and is located within the operating cavity 7. The opening of the operating cavity 7 is located on the outer wall of the clamping assembly 1. A person can reach into the operating cavity 7 through the opening and grasp the pull ring 8, thereby controlling the limiting pin 4 to extend into or out of the second channel 6.

[0037] In some embodiments, a damping ring 9 is provided at one end of the first channel 5 away from the second channel 6. The damping ring 9 is connected to the clamping assembly 1. The damping ring 9 has elastic deformation capability. The inner diameter of the damping ring 9 in its natural state is smaller than the outer diameter of the limit pin 4. The damping ring 9 provides a damping sense for the sliding insertion and removal of the limit pin 4, preventing the limit pin 4 from detaching from the first channel 5. Furthermore, a pressure plate 10 is provided on the side of the damping ring 9 facing away from the first channel 5. The pressure plate 10 can be connected to the connecting assembly 2 by fasteners. The pressure plate 10 presses the damping ring 9 against the connecting assembly 2 to prevent the damping ring 9 from falling off. The limit pin 4 passes through the pressure plate 10.

[0038] In some embodiments, the end of the stop pin 4 distal from the intermediate shaft 3 is connected to a drive assembly that drives the stop pin 4 into and out of the second channel 6. Specifically, the drive assembly comprises a telescopic cylinder, the fixed end of which is connected to the clamping assembly 1 and the movable end of which is connected to the stop pin 4. Alternatively, the drive assembly may be an electric telescopic rod or a linear module. This drive assembly drives the stop pin 4 into and out of the second channel 6, eliminating the need for manual manipulation of the stop pin 4, resulting in labor-saving and simplified operation.

[0039] In some embodiments, as Figure 4 As shown, the connecting assembly 2 is provided with a first hole 21, which can be a countersunk hole. When the connecting assembly 2 and the intermediate shaft 3 are installed together, the intermediate shaft 3 is located in the first hole 21. An annular groove is formed on the intermediate shaft 3, and an elastic protrusion is formed on the inner wall of the first hole 21. The elastic protrusion forms a concave-convex fit with the annular groove. When the connecting assembly 2 and the intermediate shaft 3 are installed together, the restraining fit between the elastic protrusion and the annular groove prevents the connecting assembly 2 from sliding or rotating relative to the intermediate shaft 3.

[0040] Another embodiment of the present application provides a water propeller 100, such as Figure 4 and Figure 5 As shown, it includes a main body and the above-mentioned connecting device, and the main body is connected to the connecting component 2. The connecting component 2 is provided with a mounting position 22, and the mounting position 22 is used to install the main body, which is used to provide power to the water body 200 and drive the water body 200 to move.

[0041] Another embodiment of the present application provides a mobile device for use in water areas, such as Figure 6 As shown, it includes a water area carrier 200 and the above-mentioned water area propeller 100, and the clamping assembly 1 is clamped on the water area carrier 200. The water area carrier 200 can move in the water area and can carry people or objects. The water area propeller 100 is installed on the water area carrier 200, and is used to provide power to the water area carrier 200 and drive the water area carrier 200 to move. The clamping assembly 1 includes a clamp, which clamps the tail of the water area carrier 200. The movable device in the water area can be a commercial ship, fishing boat, passenger ship, yacht, and other types of water transportation vehicles, and can also be a water area inspection equipment or water area management equipment and other equipment that can move in the water area.
