Description

Technical Field

[0001] This utility model relates to the technical field of Kaiyak steering structure, specifically to a Kaiyak steering adjustment structure. Background Technology

[0002] Kayak boats are popular as lightweight and flexible water sports vessels due to their maneuverability and recreational value. In order to improve sailing efficiency, reduce paddling burden, or meet specific needs (such as fishing and photography), more and more kayaks are equipped with propulsion devices and outboard motors (usually propellers). This propulsion system greatly enhances the kayak's range and ease of handling.

[0003] However, the propulsion systems and outboard motors used in existing Kayak boats typically present the following technical challenges when making steering adjustments: When turning, the operator needs to turn around, using one hand to hold the rudder to control direction and the other to hold the hull for balance, while simultaneously facing forward to check the water surface. This puts significant strain on the operator's lower back during prolonged operation, affecting comfort. Furthermore, existing Kayak boats vary considerably in size and hull structure, requiring customized installation of additional steering mechanisms, thus impacting versatility. Therefore, a device is needed to solve these problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a KAIAK steering adjustment structure, which solves the problems of insufficient comfort during manual steering and poor versatility of retrofitted steering structures.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a Kayak steering adjustment structure, including a mounting plate and a drive motor for driving the Kayak to move, wherein the bottom of the drive motor is provided with a connecting shaft for supporting the drive motor, and a mounting seat is fixedly connected to one side of the mounting plate, and the connecting shaft passes through the mounting seat and is rotatably connected to the mounting seat.

[0006] A housing is fixedly connected to one side of the mounting plate. A servo motor is installed inside the housing. An active rod is rotatably connected to the bottom of the housing. The output shaft of the servo motor is connected to the active rod via gears. A transmission mechanism is provided at the end of the active rod away from the housing. A clamping mechanism is provided at the end of the transmission mechanism away from the active rod. The clamping mechanism is detachably connected to the outer surface of the connecting shaft to drive the connecting shaft to rotate.

[0007] Optionally, the transmission mechanism includes a connecting rod and a driven rod, the connecting rod being rotatably connected to one end of the driving rod, the driven rod being rotatably connected to the end of the connecting rod away from the driving rod, and the clamping mechanism being fixedly connected to the end of the driven rod away from the connecting rod.

[0008] Optionally, the connecting rod includes a support rod, an adjusting seat, and an adjusting nut. There are two adjusting seats, which are threaded to both ends of the support rod. The adjusting nut is threaded to the outer surface of the support rod, with one end tightly fitted to one side of the adjusting seat.

[0009] Optionally, the adjusting seat is provided with a limiting mechanism at one end near the driven rod, the limiting mechanism being used to connect the adjusting seat and the driven rod.

[0010] Optionally, the limiting mechanism includes a positioning pin and a limiting pin. The positioning pin passes through both the adjusting seat and the driven rod simultaneously. A positioning hole is provided at the bottom of the positioning pin. The limiting pin is inserted into the positioning hole to prevent the positioning pin from being pulled out of the adjusting seat.

[0011] Optionally, the limiting pin is U-shaped, and the opening at one end of the limiting pin is larger than the diameter of the positioning hole.

[0012] Optionally, the clamping mechanism includes a fixed clamp and a movable clamp. The fixed clamp is fixedly connected to the end of the driven rod away from the adjusting seat, and the movable clamp is fixedly connected to one side of the fixed clamp by bolts.

[0013] Optionally, the inner walls of both the fixed clamp and the movable clamp are knurled to increase friction with the connecting shaft.

[0014] This utility model provides a Kaiyak steering adjustment structure, which has the following beneficial effects:

[0015] This utility model provides a kayak steering adjustment structure. Through the cooperation of a mounting base and a connecting shaft, the mounting base supports the position of the connecting shaft. The housing, servo motor, and drive rod, all mounted on the mounting plate, work together to allow the servo motor to drive the drive rod to rotate. A transmission mechanism at one end of the drive rod further facilitates this adjustment, causing the connecting shaft to rotate and thus adjusting the orientation of the propeller at the bottom of the connecting shaft. Adjusting the propeller's propulsion direction can be done directly facing forward, eliminating the need for prolonged waist twisting and improving comfort. Furthermore, a clamping mechanism on one side of the transmission mechanism allows this device to be directly applied to ordinary kayak boats, making later installation more convenient and improving the device's versatility.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0021] Please see Figures 1 to 3 This utility model provides a technical solution: a swivel steering adjustment structure, including a mounting plate 1 fixedly installed at the stern of the swivel hull and a drive motor 2 for driving the swivel hull to move. The bottom of the drive motor 2 is provided with a connecting shaft 3 for supporting the drive motor 2. A mounting base 4 is fixedly connected to one side of the mounting plate 1. The connecting shaft 3 passes through the mounting base 4 and is rotatably connected to the mounting base 4.

[0022] A housing 5 is fixedly connected to one side of the mounting plate 1. A servo motor 6 is installed inside the housing 5. An active rod 7 is rotatably connected to the bottom of the housing 5. The output shaft of the servo motor 6 is connected to the active rod 7 via a gear. Specifically, an active gear is fixedly installed on the output shaft of the servo motor 6. One end of the active rod 7 is fixedly installed on a vertical rotating shaft. A driven gear is fixedly installed on the vertical rotating shaft. The active gear and the driven gear mesh and transmit power. A transmission mechanism is provided at the end of the active rod 7 away from the housing 5. A clamping mechanism is provided at the end of the transmission mechanism away from the active rod 7. The clamping mechanism is detachably connected to the outer surface of the connecting shaft 3 to drive the connecting shaft 3 to rotate.

[0023] Mounting plate 1 can be installed at the stern of a standard Kayak boat. Mounting base 4 clamps the connecting shaft 3 at the bottom of the drive motor 2, preventing the connecting shaft 3 from falling. While clamping the connecting shaft 3, mounting base 4 allows the connecting shaft 3 to rotate. The connecting shaft 3 is hollow and contains a transmission shaft to drive the propeller at the bottom, thus propelling the boat forward. Housing 5 is located on the other side of mounting plate 1. Servo motor 6 drives the drive rod 7 to rotate. During the rotation of the drive rod 7, the transmission mechanism drives the clamping mechanism, thereby rotating the connecting shaft 3 to adjust the propulsion direction of the bottom propeller. Housing 5 also contains a control chip and a receiving antenna. The control chip can adjust the rotation direction of the servo motor 6, and the receiving antenna can receive 2.4GHz signals. With a wireless handheld control device, the operator can sit inside the Kayak boat facing forward and control the rotation angle of the rear servo motor 6 via the handheld device, thus adjusting the propulsion direction. Adjusting the forward angle avoids the operator having to lean to the side, making control more convenient and improving comfort. In this embodiment, the structure and control principle of the wireless handheld control device, control chip, and receiving antenna are all existing technologies and will not be described in detail here.

[0024] In this embodiment, as a preferred option, the transmission mechanism includes a connecting rod and a driven rod 8. The connecting rod is rotatably connected to one end of the driving rod 7, and the driven rod 8 is rotatably connected to the end of the connecting rod away from the driving rod 7. The clamping mechanism is fixedly connected to the end of the driven rod 8 away from the connecting rod. The connecting rod includes a support rod 9, an adjusting seat 10, and an adjusting nut 11. There are two adjusting seats 10, which are respectively threaded to both ends of the support rod 9. The adjusting nut 11 is threaded to the outer surface of the support rod 9, and one end is tightly fitted to one side of the adjusting seat 10.

[0025] The support rod 9 is connected to the driving rod 7 and the driven rod 8 through the adjusting seats 10 at both ends. During the rotation of the driving rod 7, the driving rod 7 drives the support rod 9 to move, thereby causing the support rod 9 to drive the driven rod 8 to rotate, so as to adjust the pushing direction of the connecting shaft 3. The support rod 9 and the adjusting seat 10 are threaded together. By rotating the adjusting seat 10, the relative position of the adjusting seat 10 and the support rod 9 can be adjusted, thereby adjusting the overall length of the connecting rod. During later installation, the overall length of the connecting rod can be adjusted according to the installation position to adapt to different installation positions and improve the versatility of the device.

[0026] In this embodiment, as a preferred option, the adjusting seat 10 is provided with a limiting mechanism at one end near the driven rod 8. The limiting mechanism is used to connect the adjusting seat 10 and the driven rod 8. The limiting mechanism includes a positioning pin 12 and a limiting pin 13. The positioning pin 12 passes through the adjusting seat 10 and the driven rod 8 simultaneously. A positioning hole 14 is opened at the bottom of the positioning pin 12. The limiting pin 13 is inserted into the inside of the positioning hole 14 to prevent the positioning pin 12 from being pulled out of the adjusting seat 10. The limiting pin 13 is U-shaped, and the opening at one end of the limiting pin 13 is larger than the diameter of the positioning hole 14.

[0027] After the positioning pin 12 is inserted into the adjusting seat 10 and the driven rod 8, the ends of the adjusting seat 10 and the driven rod 8 can be constrained to connect them together. The limiting pin 13 is a flexible metal piece. After the limiting pin 13 is inserted into the positioning hole 14, one end of the limiting pin 13 will spring open, making one end of the limiting pin 13 larger than the size of the positioning hole 14, preventing the limiting pin 13 from being pulled out of the positioning hole 14. The other end of the limiting pin 13 is provided with a stop piece to prevent the limiting pin 13 from passing through the positioning hole 14 from the other end. When disassembly is required, press the expansion part at one end of the limiting pin 13 to flatten the limiting pin 13 and pull it out. The limiting pin 13 is flexible and can return to its original shape after being removed.

[0028] In this embodiment, as a preferred option, the clamping mechanism includes a fixed clamp 15 and a movable clamp 16. The fixed clamp 15 is fixedly connected to the end of the driven rod 8 away from the adjusting seat 10. The movable clamp 16 is fixedly connected to one side of the fixed clamp 15 by bolts. The fixed clamp 15 and the movable clamp 16 are located on both sides of the connecting shaft 3 to clamp and fix the connecting shaft 3. The inner walls of the fixed clamp 15 and the movable clamp 16 are both provided with knurling to increase the friction with the connecting shaft 3.

[0029] Both the fixed clamp 15 and the movable clamp 16 have through holes on both sides. The fixed clamp 15 and the movable clamp 16 can be fixed to the outer surface of the connecting shaft 3 using bolts. The inner diameter of the fixed clamp 15 and the movable clamp 16 is matched with the outer diameter of the connecting shaft 3 to ensure that the fixed clamp 15 and the movable clamp 16 are in close contact with the connecting shaft 3. The knurling on the inner wall can further improve the clamping firmness to prevent slippage during clamping and ensure the accuracy of the rotation angle.

[0030] In this invention, the working steps of the device are as follows:

[0031] 1. Fix the mounting plate 1 to the stern of the Kayak boat. Use bolts to fix the fixing clip 15 and the movable clip 16 to the outer surface of the connecting shaft 3. Adjust the relative length of the support rod 9 and the adjusting seat 10 so that the adjusting seats 10 at both ends can be connected to the driving rod 7 and the driven rod 8.

[0032] 2. A bearing is fitted on the inner wall of the end of the support rod 9 near the drive rod 7. Bolts are used to connect the support rod 9 and the drive rod 7 together to avoid tightening and to ensure that the support rod 9 and the drive rod 7 can rotate relative to each other.

[0033] 3. After the support rod 9 is connected to the driven rod 8, insert the positioning pin 12, and then insert the limit pin 13 into the positioning hole 14 to fix the position of the positioning pin 12.

[0034] 4. After installation, the rotation direction and angle of the servo motor 6 can be controlled by a wireless handheld control device, thereby adjusting the propulsion direction of the propeller at the bottom of the drive motor 2.

Specific examples have been used to illustrate the principles and implementation methods of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
