Description

Technical Field

[0001] The present invention relates to the technical field of surfboards, and specifically to a controller for surfboards that is convenient to install. Background Art

[0002] A surfboard is a sports equipment for people to engage in surfing. Due to its relatively high operation difficulty, beginners usually use an auxiliary controller to achieve core stability and direction control during use. The control stability and installation convenience of the auxiliary controller directly affect the user experience. Traditional surfboard controllers mostly use mechanical latches or single suction cups for fixation, and have the following limitations: Insufficient fixing reliability: A single suction cup is prone to loosening under the impact of waves, while a mechanical latch requires complex operations and has poor adaptability, making it difficult to be compatible with surfboards of different thicknesses or curved surface designs; Complicated installation process: Existing fixing devices often require tool assistance or multiple manual adjustments, which are time-consuming and laborious, especially inconvenient to operate in a wet and slippery environment; Low steering control accuracy: Traditional steering mechanisms rely on direct mechanical linkages, with low transmission efficiency and lagging response. Novices are difficult to precisely control the direction and are prone to losing balance; Lack of adaptive adjustment: The adsorption force of the fixing device depends on the initial installation state and cannot be dynamically adjusted according to the use environment (such as water flow changes). After long-term use, the stability is prone to decline due to air leakage in the airbag or structural fatigue. Summary of the Invention

[0003] The purpose of the present invention is to provide a controller for surfboards that is convenient to install, so as to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the present invention provides the following technical solution: A controller for surfboards that is convenient to install, including a docking seat, a fixing component, and a control component. A first suction cup is arranged at the inner bottom end of the docking seat, and a buffer seat is arranged inside the docking seat. A fixing component is arranged at the inner top end of the docking seat, and a control component is arranged at the outer end of the top of the docking seat. The control component includes a rotating shaft. A first pulley is arranged at the outer bottom end of the rotating shaft, and a cam is arranged at the outer bottom end of the first pulley. A rotating base is arranged at the outer top end of the rotating shaft, and a rotating seat is arranged inside the rotating base. A telescopic rod is connected to the outer top end of the rotating seat, and a holding handle is arranged at the end of the telescopic rod. The outer end of the first pulley is connected to a first belt, and a transmission component is arranged at the end of the first belt. A surfboard is arranged inside the docking seat.

[0005] Furthermore, a rotating disk is arranged at the outer end of the top of the docking seat, and a threaded shaft is arranged at the bottom end of the rotating disk. An adjusting plate is arranged at the bottom end of the threaded shaft.

[0006] Further, the threaded shaft is in threaded connection with the docking seat, and the rotating disk drives the position adjusting plate to rotate through the threaded shaft.

[0007] Further, the fixing assembly includes a second suction cup. A return spring is arranged between the second suction cup and the docking seat. A fixing plate is arranged inside the top of the second suction cup. An expansion airbag is fixed to the outer end of the fixing plate. A one-way exhaust valve is arranged at the outer end of the top of the expansion airbag. A one-way intake valve is arranged at the outer end of the bottom of the expansion airbag. A ventilation groove is formed inside the second suction cup. A pressing plate is arranged at the outer end of the top of the second suction cup. A pressure spring is arranged between the pressing plate and the second suction cup.

[0008] Further, the bottom surface of the position adjusting plate is in fit with the top surface of the second suction cup, and the second suction cup is elastically connected with the return spring.

[0009] Further, the ventilation groove is communicated with the one-way intake valve, and the one-way intake valve is communicated with the one-way exhaust valve through the expansion airbag.

[0010] Further, the cam is in fit with the pressing plate, and the displacement of the pressing plate squeezes the expansion airbag.

[0011] Further, the transmission assembly includes a driven gear. A meshing gear is meshed with the outer end of the driven gear. The meshing gear is coaxially connected with a first bevel gear. A second bevel gear is meshed with the outer end of the first bevel gear. A third bevel gear is meshed with the outer end of the second bevel gear. The third bevel gear is coaxially connected with a second pulley.

[0012] Further, the first pulley drives the driven gear to rotate through the first belt. The driven gear drives the second pulley to rotate through the meshing of the meshing gear, the first bevel gear, the second bevel gear and the third bevel gear.

[0013] Further, a second belt is arranged at the outer end of the second pulley. A driven rotating seat is arranged at the end of the second belt. A steering paddle is connected to the outer end of the bottom of the driven rotating seat. The second pulley drives the driven rotating seat to rotate through the second belt.

[0014] The present invention provides a controller for a surfboard that is convenient to install, and has the following beneficial effects: 1. After the operator of the present invention inserts the head of the surfboard into the U-shaped inlet of the docking seat, the front end of the surfboard enters the buffer seat made of flexible rubber material to achieve wrapping and buffering, preventing collision damage. At this time, the bottom surface of the surfboard fits with the first suction cup to complete preliminary adsorption. The fusiform structure of the docking seat matches the shape of the surfboard, facilitating visual calibration and alignment. The operator rotates the rotating disk, drives the positioning plate to press down through the threaded shaft, pushes the second suction cup to move down and stretches the return spring until it adsorbs the top surface of the surfboard. Through the two-way adsorption of the first suction cup and the second suction cup, combined with the buffer seat to form a triangular support, the stable fixation of the surfboard is realized. This design adapts to different sizes of surfboards through the second suction cup with adjustable height, and only needs to insert and align and rotate the rotating disk to complete the installation, combining stability and operation convenience.

[0015] 2. When the operator of the present invention swings the holding handle left and right, it can drive the rotating base to drive the rotating shaft to rotate synchronously. Then, the power is transmitted to the driven gear through the first pulley and the first belt. The driven gear drives the second pulley to rotate through the meshing gear bevel gear set, and then drives the driven rotating seat and the steering paddle to adjust the direction through the second belt. The operator only needs to control the orientation of the telescopic rod by holding the handle, and the steering paddle can be deflected synchronously with the telescopic rod, realizing precise and flexible adjustment of the direction of the surfboard. At the same time, the design of the holding handle can not only improve the steering control efficiency, but also provide a stable grasping fulcrum for the operator, especially for beginners, to ensure maintaining a balanced posture on the surfboard during steering.

[0016] 3. When the operator swings the holding handle, the cam rotates synchronously with the rotating shaft. When the cam bump faces forward, the telescopic rod is in the upright position and presses the pressing plate, compressing the pressure spring to discharge the gas in the expansion airbag through the one-way exhaust valve. During steering, the cam bump deflects, and the pressing plate resets under the rebound of the pressure spring. The expansion airbag resumes its original state and inhales external air through the one-way intake valve and the ventilation groove. Since the ventilation groove is communicated with the inner cavity of the second suction cup, this process can automatically empty the air inside the second suction cup, enhancing its adsorption force on the top surface of the surfboard. Combined with the low risk of loosening of the first suction cup at the bottom, this design effectively improves the overall fixing stability of the device, avoids accidental detachment of the second suction cup during surfing, and ensures operation safety.

Detailed implementation manners

[0019] Please refer to Figures 1 to 9, the present invention provides a technical solution: A controller for a surfboard that is easy to install, including a docking seat 1, a fixing component 7, and a control component 8. At the inner bottom end of the docking seat 1, a first suction cup 2 is arranged, and a buffer seat 3 is arranged inside the docking seat 1. At the inner top end of the docking seat 1, a fixing component 7 is arranged, and at the outer end of the top of the docking seat 1, a control component 8 is arranged. The control component 8 includes a rotating shaft 801. At the outer bottom end of the rotating shaft 801, a first pulley 802 is arranged, and at the outer bottom end of the first pulley 802, a cam 803 is arranged. At the outer top end of the rotating shaft 801, a rotating base 804 is arranged, and inside the rotating base 804, a rotating seat 805 is arranged. At the outer top end of the rotating seat 805, a telescopic rod 806 is connected, and at the end of the telescopic rod 806, a grip handle 807 is arranged. The outer end of the first pulley 802 is connected to a first belt 9, and at the end of the first belt 9, a transmission component 10 is arranged. Inside the docking seat 1, a surfboard 14 is arranged.

[0020] The specific operation is as follows. After the operator inserts the head of the surfboard 14 that needs to be docked with the controller into the U-shaped entrance of the docking seat 1, the head of the surfboard 14 can be inserted into the buffer seat 3. The buffer seat 3 is made of flexible rubber material, which enables the buffer seat 3 to wrap and buffer the front end of the surfboard 14 to avoid damage to the surfboard 14 during the docking process with the device. After the front end of the surfboard 14 is inserted into the buffer seat 3, its bottom surface can be attached to the first suction cup 2, which enables the first suction cup 2 to adsorb and fix the surfboard 14. Since the docking seat 1 is generally spindle-shaped and similar to the overall shape of the surfboard 14, when the head of the surfboard 14 is inserted into the docking seat 1, the operator can simply visually determine whether the surfboard 14 is skewed inside the docking seat 1.

[0021] Please refer to Figures 1 to 4The top outer end of the docking seat 1 is provided with a rotating disk 4, and the bottom end of the rotating disk 4 is provided with a threaded shaft 5, and the bottom end of the threaded shaft 5 is provided with an adjustment plate 6, the threaded shaft 5 is threadedly connected to the docking seat 1, and the rotating disk 4 drives the adjustment plate 6 to rotate through the threaded shaft 5, and the fixing component 7 includes a second suction cup 701, a return spring 702 is arranged between the second suction cup 701 and the docking seat 1, and a fixing plate 703 is arranged on the inner side of the top of the second suction cup 701, and an expansion airbag 704 is fixed on the outer end of the fixing plate 703, a one-way exhaust valve 705 is arranged on the top outer end of the expansion airbag 704, and a One-way air intake valve 706, a venting groove 707 is provided inside the second suction cup 701, and a squeezing plate 708 is arranged at the outer end of the top of the second suction cup 701, a pressure spring 709 is arranged between the squeezing plate 708 and the second suction cup 701, the bottom surface of the adjustment plate 6 is in contact with the top surface of the second suction cup 701, and the second suction cup 701 is elastically connected to the return spring 702, the venting groove 707 is communicated with the one-way air intake valve 706, and the one-way air intake valve 706 is connected with the one-way exhaust valve 705 through the expansion airbag 704, the cam 803 is in contact with the squeezing plate 708, and the squeezing plate 708 is displaced to squeeze the expansion airbag 704; The specific operation is as follows. After the first suction cup 2 has adsorbed and fixed the surfboard 14, the operator twists the rotating disk 4, which can make the rotating disk 4 drive the threaded shaft 5 and the adjusting plate 6 to rotate. Since the rotating disk 4 is threadedly connected to the docking seat 1, the threaded shaft 5 can drive the adjusting plate 6 to move downward during the rotation of the rotating disk 4. Since the bottom surface of the adjusting plate 6 is in contact with the top surface of the second suction cup 701, the downward movement of the adjusting plate 6 can push the second suction cup 701 to move downward. During the downward movement of the second suction cup 701, the reset spring 702 can be stretched and can approach the top surface of the surfboard 14 until the second suction cup 701 is in contact with the surfboard 14. The surfboard 14 and the second suction cup 701 are in contact. After closing, the second suction cup 701 can adsorb the top surface of the surfboard 14, and the docking seat 1 can stably fix the surfboard 14 through the adsorption and clamping of the first suction cup 2 and the second suction cup 701, and the buffer seat 3 can cooperate with the first suction cup 2 and the second suction cup 701 to form a triangular support for the surfboard 14, which improves the fixation stability of the surfboard 14. In addition, because the height position of the second suction cup 701 is adjustable, the device can fix surfboards 14 of different sizes. In the above operation process, the operator only needs to simply insert the surfboard 14 into the docking seat 1, align it, and twist the rotating disk 4 to achieve installation, which makes the device highly convenient to install.

[0022] See also Figures 5 to 8, the transmission assembly 10 includes a driven gear 1001, an engaging gear 1002 is engaged with the outer end of the driven gear 1001, and a first bevel gear 1003 is coaxially connected to the engaging gear 1002. A second bevel gear 1004 is engaged with the outer end of the first bevel gear 1003, and a third bevel gear 1005 is engaged with the outer end of the second bevel gear 1004. A second pulley 1006 is coaxially connected to the third bevel gear 1005. The first pulley 802 drives the driven gear 1001 to rotate through the first belt 9, and the driven gear 1001 drives the second pulley 1006 to rotate through the engagement of the engaging gear 1002, the first bevel gear 1003, the second bevel gear 1004, and the third bevel gear 1005. A second belt 11 is provided at the outer end of the second pulley 1006, and a driven swivel 12 is provided at the end of the second belt 11. A steering paddle 13 is connected to the outer bottom end of the driven swivel 12. The second pulley 1006 drives the driven swivel 12 to rotate through the second belt 11; The specific operation is as follows. After the docking base 1 and the surfboard 14 are docked, the operator places the surfboard 14 in the water and stands on the surfboard 14. The rotating seat 805 can adjust the deflection angle through the rotating base 804, and the telescopic rod 806 can adjust the height position of the holding handle 807 through telescoping. This enables the operator to hold the holding handle 807 at the most comfortable angle when standing on the surfboard 14. When the operator swings the holding handle 807 left and right, the holding handle 807 can drive the rotating shaft 801 to rotate left and right through the rotating base 804. During the rotation of the rotating shaft 801, it can drive the first belt 9 to rotate through the first pulley 802. The first belt 9 will transmit the rotational force to the driven gear 1001. The driven gear 1001 drives the first bevel gear 1003 to rotate through meshing with the meshing gear 1002. The first bevel gear 1003 meshes with the second bevel gear 1004, and the second bevel gear 1004 meshes with the third bevel gear 1005. This enables the third bevel gear 1005 to drive the coaxial second pulley 1006 to rotate. During the rotation of the second pulley 1006, it can drive the driven rotating seat 12 to rotate through the second belt 11. The driven rotating seat 12 is connected to the steering paddle 13. Through the above operations, the operator only needs to swing the holding handle 807 to adjust the orientation of the telescopic rod 806, and then the orientation of the steering paddle 13 can be changed. And through the transmission of the gear set, the orientation of the steering paddle 13 is consistent with the orientation of the telescopic rod 806. This enables the operator to flexibly and precisely control the direction of the surfboard 14 during surfing. In addition, when the operator holds the holding handle 807, the stability of standing on the surfboard 14 can be improved. This enables novices to maintain a good standing posture on the surfboard 14 during the turning process when using the device. In addition, when the operator swings the holding handle 807 to drive the rotating shaft 801 to rotate, the cam 803 will rotate synchronously. When the convex block of the cam 803 faces directly forward, the telescopic rod 806 is in the upright position. When the telescopic rod 806 is in the upright position, it will squeeze the pressing plate 708. This enables the pressing plate 708 to displace through the compression of the pressure spring 709 and squeeze the expansion airbag 704. When the expansion airbag 704 is squeezed, the gas inside it will be discharged through the one-way exhaust valve 705. When the surfboard 14 turns, the swing of the holding handle 807 will cause the convex block of the cam 803 to move away from the top of the pressing plate 708. The pressing plate 708 resets through the rebound of the pressure spring 709. At this time, the expansion airbag 704 will recover. During the recovery process of the expansion airbag 704, the volume of the internal cavity increases. This enables the expansion airbag 704 to inhale the outside air through the one-way intake valve 706. The one-way intake valve 706 is connected to the ventilation groove 707, and the ventilation groove 707 is connected to the inner cavity of the second suction cup 701. Through this design, the device can automatically empty the air in the inner cavity of the second suction cup 701 during the turning process. Since the first suction cup 2 is located at the bottom of the surfboard 14, the probability of loosening is relatively low. By emptying the air in the second suction cup 701,The adsorption stability between the second suction cup 701 and the surfboard 14 can be improved, which can prevent the device from being loosened from the surfboard 14 during use, and can greatly improve the use stability of the device.

[0023] In summary, the controller for surfboards that is easy to install, when in use, firstly, the operator inserts the head of the surfboard 14 that needs to be docked with the controller into the U-shaped entrance of the docking seat 1, and then the head of the surfboard 14 can be inserted into the buffer seat 3. The buffer seat 3 is made of a flexible rubber material, which enables the buffer seat 3 to wrap and buffer the front end of the surfboard 14 to avoid damage to the surfboard 14 during the docking process. After the front end of the surfboard 14 is inserted into the buffer seat 3, its bottom surface can fit with the first suction cup 2, which enables the first suction cup 2 to absorb and fix the surfboard 14. Because the docking seat 1 is shuttle-shaped as a whole, which is similar to the overall shape of the surfboard 14, when the head of the surfboard 14 is inserted into the docking seat 1, the operator only needs to make a simple visual judgment to determine whether the surfboard 14 is deflected in the docking seat 1. Then, after the first suction cup 2 has adsorbed and fixed the surfboard 14, the operator twists the rotating disk 4, which can make the rotating disk 4 drive the threaded shaft 5 and the adjusting plate 6 to rotate. Since the rotating disk 4 is threadedly connected to the docking seat 1, the threaded shaft 5 can drive the adjusting plate 6 to move downward during the rotation of the rotating disk 4. Since the bottom surface of the adjusting plate 6 fits with the top surface of the second suction cup 701, the downward movement of the adjusting plate 6 can push the second suction cup 701 to move downward. During the downward movement of the second suction cup 701, the reset spring 702 can be stretched and can approach the top surface of the surfboard 14 until the second suction cup 701 fits with the surfboard 14. After the surfboard 14 fits with the second suction cup 701, , the second suction cup 701 can adsorb the top surface of the surfboard 14, so that the docking seat 1 can stably fix the surfboard 14 through the adsorption and clamping of the first suction cup 2 and the second suction cup 701, and the buffer seat 3 can cooperate with the first suction cup 2 and the second suction cup 701 to form a triangular support for the surfboard 14, which improves the fixation stability of the surfboard 14. In addition, because the height position of the second suction cup 701 is adjustable, the device can fix surfboards 14 of different sizes. In the above operation process, the operator only needs to simply insert the surfboard 14 into the docking seat 1, align it, and twist the rotating disk 4 to achieve installation, which makes the device highly convenient to install; After the docking base 1 and the surfboard 14 are successfully docked, the operator places the surfboard 14 in the water and stands on the surfboard 14. The rotating seat 805 can adjust the skew angle through the rotating base 804, and the telescopic rod 806 can adjust the height position of the holding handle 807 through telescoping. This enables the operator to hold the holding handle 807 at the most comfortable angle when standing on the surfboard 14. When the operator swings the holding handle 807 left and right, the holding handle 807 can drive the rotating shaft 801 to rotate left and right through the rotating base 804. During the rotation of the rotating shaft 801, it can drive the first belt 9 to rotate through the first pulley 802. The first belt 9 will transmit the rotational force to the driven gear 1001. The driven gear 1001 drives the first bevel gear 1003 to rotate by meshing with the meshing gear 1002. The first bevel gear 1003 meshes with the second bevel gear 1004, and the second bevel gear 1004 meshes with the third bevel gear 1005. This enables the third bevel gear 1005 to drive the coaxial second pulley 1006 to rotate. During the rotation of the second pulley 1006, it can drive the driven rotating seat 12 to rotate through the second belt 11. The driven rotating seat 12 is connected to the steering paddle 13. Through the above operations, the operator only needs to swing the holding handle 807 to adjust the orientation of the telescopic rod 806, and then the orientation of the steering paddle 13 can be switched. And through the transmission of the gear set, the orientation of the steering paddle 13 is consistent with the orientation of the telescopic rod 806. This enables the operator to flexibly and precisely control the direction of the surfboard 14 during surfing. In addition, when the operator holds the holding handle 807, the stability of standing on the surfboard 14 can be improved. This enables beginners to maintain a good standing posture on the surfboard 14 during the turning process when using the device; Finally, when the operator drives the rotating shaft 801 to rotate by swinging the holding handle 807, the cam 803 will be driven to rotate synchronously. When the convex block of the cam 803 faces directly forward, the telescopic rod 806 is in the upright position. When the telescopic rod 806 is in the upright position, it will squeeze the pressing plate 708, which enables the pressing plate 708 to displace through the compression pressure spring 709 and squeeze the expansion airbag 704. When the expansion airbag 704 is squeezed, the gas inside it will be discharged through the one-way exhaust valve 705. When the surfboard 14 turns, the swing of the holding handle 807 will cause the convex block of the cam 803 to move away from the top of the pressing plate 708, and the pressing plate 708 will reset by the rebound of the pressure spring 709. At this time, the expansion airbag 704 will recover. During the recovery process of the expansion airbag 704, the volume of the internal cavity increases, which causes the expansion airbag 704 to inhale the external air through the one-way intake valve 706. The one-way intake valve 706 is connected to the ventilation groove 707, and the ventilation groove 707 is connected to the inner cavity of the second suction cup 701. Through this design, the device can automatically empty the air in the inner cavity of the second suction cup 701 during the turning process. Since the first suction cup 2 is located at the bottom of the surfboard 14, the probability of loosening is relatively low. By emptying the air in the second suction cup 701, the adsorption stability between the second suction cup 701 and the surfboard 14 can be improved, which can prevent the device from loosening from the surfboard 14 during use and greatly improve the use stability of the device.
