Description

A propulsion device for a powered surfboard and its method of use Technical Field

[0001] This invention relates to the field of surfboard technology, specifically to a propulsion device for a powered surfboard and its method of use. Background Technology

[0002] Surfing is a popular sport due to its thrilling nature and the physical benefits it provides. However, ordinary surfboards rely on the propulsion of waves to function. They only truly bring out the charm of surfing in strong winds and high waves; in calm waters, they are ineffective and cannot provide the full enjoyment of the sport. Therefore, some developers invented gasoline-powered surfboards. These surfboards use a gasoline engine to drive an underwater propulsion system, which in turn propels the surfboard forward.

[0003] Nowadays, environmental factors cause a large amount of seaweed or garbage to float on most sea surfaces. Modern motor surfboards are equipped with protective nets at their water inlets to prevent seaweed from getting tangled in the propellers. However, a lot of seaweed or garbage can clog the protective nets, causing the motor surfboard to slow down or stop, thus affecting the user's performance. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a propulsion device for a powered surfboard and its usage method, solving the problem of seaweed or garbage clogging the protective net.

[0006] By adopting the above technical solution: the controller can control the gas engine, electric telescopic rod, and steering assembly, enabling the surfboard to easily surf on the sea surface by pushing and steering the assembly; when seaweed or debris is blocked on the protective frame 1, the electric telescopic rod pushes the moving frame, causing the moving frame to drive multiple rotating frames 2 downwards through multiple rotating frames 1, allowing the rotating frames 2 to wash away the seaweed or debris on the protective frame 1 by the sea current at the bottom of the surfboard, thus clearing the seaweed or debris on the protective frame 1 and achieving the effect of preventing the water inlet at the bottom of the surfboard from becoming blocked.

[0007] Preferably, the steering assembly includes a servo motor, which is installed inside the surfboard. The output end of the servo motor is fixedly connected to a first synchronous pulley. The teeth of the first synchronous pulley are meshed with two synchronous belts. The inner wall of the surfboard is rotatably connected to two second connecting rods. The outer wall of the second connecting rods is fixedly connected to a second synchronous pulley and two gears. The inner wall of the surfboard is slidably connected to a movable plate. The top end of the movable plate is fixedly connected to two racks.

[0008] Preferably, the timing belt is meshed with the tooth end of the timing pulley two, and the two gears are meshed with the tooth end of the rack.

[0009] Preferably, the propulsion assembly includes rotating rods, two of which are rotatably connected to the inner wall of the surfboard. One end of each rotating rod is fixedly connected to a bevel gear three, and the other end of each rotating rod is fixedly connected to two propellers. Two water spray frames are installed on the inner wall of the other end of the surfboard, and a connecting frame is fixedly connected to the inner wall of each water spray frame. Two connecting rods one are rotatably connected to the inner wall of the surfboard, and both ends of each connecting rod one are fixedly connected to bevel gear two. One end of the rotating shaft is fixedly connected to a bevel gear one.

[0010] Preferably, the two bevel gears are meshed at the tooth ends of the first bevel gear, the second bevel gear is meshed at the tooth ends of the third bevel gear, and the other end of the rotating rod is rotatably connected to the inner wall of the connecting frame.

[0011] Preferably, the two rubber rings and the movable frame are slidably connected to the inner wall of the surfboard.

[0012] Preferably, the rotating frame one is rotatably connected to one end of the rotating frame two, and multiple rotating frames one and rotating frames two are slidably connected to the bottom end of the surfboard.

[0013] Preferably, the rotating shaft is rotatably connected to the inner wall of the surfboard, the blades are installed at the air inlet of the exhaust pipe, and the exhaust outlet of the exhaust pipe is located above the protective frame.

[0014] Preferably, the connection point between the movable frame and the multiple rotating frames is located between the protective frame and the surfboard.

[0015] Preferably, in step S1, the user places the powered surfboard on the sea surface and stands on it; in step S2, the user controls the gas engine, electric telescopic rod, and servo motor via a controller, causing the gas engine to move the surfboard by pushing components; the electric telescopic rod cleans seaweed or debris from the protective frame 1 via a moving frame, rotating frame 1, and rotating frame 2; and the servo motor moves the moving board left and right at the bottom of the surfboard via synchronous pulley 1, synchronous belt, and synchronous pulley 2, so that the moving board can block one of the water inlets at the bottom of the surfboard, thereby facilitating the surfboard's turning; in step S3, after surfing, the user holds the air inlet, places the powered surfboard on the support frame, and rinses and maintains the powered surfboard for the next use.

[0016] This invention provides a propulsion device for a powered surfboard and its method of use. It has the following advantages: 1. This invention uses an electric telescopic rod to push a movable frame, causing multiple rotating frames (one and two) to rotate downwards, pushing obstructions into the current at the bottom of the board and washing them away, thereby clearing the protective frame and preventing blockage of the surfboard's bottom inlet.

[0017] 2. In this invention, the first synchronous pulley is connected to two second synchronous pulleys via two synchronous belts, and together with the second connecting rod, they form a transmission structure. A servo motor drives the gears on both sides to rotate. The gears mesh with the rack, allowing the servo motor to indirectly control the left and right movement of the moving board at the bottom of the surfboard, thereby blocking one water inlet and allowing the other spray nozzle to spray water. This achieves the effect of facilitating surfboard turning. Attached Figure Description

[0020] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please refer to Figures 1-7. This embodiment of the invention provides a propulsion device for a powered surfboard, including a surfboard 1. A controller 2 is mounted on one end of the surfboard 1, a tail fin 3 is mounted on the bottom end of the surfboard 1, a propulsion assembly is disposed inside the surfboard 1, a gas engine 4 is installed inside the surfboard 1, a rotating shaft 5 is mounted on the output end of the gas engine 4, a blade 7 is mounted on one end of the rotating shaft 5, two ventilation channels 24 are opened inside the surfboard 1, an exhaust pipe 15 is installed inside the surfboard 1, and two air intake pipes 23 are installed on one end of the surfboard 1. Two protective frames, 20 and 22, are installed at the bottom of the surfboard 1. Multiple rotating frames 21 are rotatably connected to one end of the protective frame 20. Two electrically operated telescopic rods 16 are installed inside the surfboard 1. A movable frame 17 is fixedly connected to one end of each electric telescopic rod 16. A rubber ring 18 is installed at one end of each movable frame 17, and multiple rotating frames 19 are rotatably connected to the other end of each movable frame 17. A steering assembly 25 is installed inside the surfboard 1. The propulsion assembly includes rotating rods 10. Two rotating rods 10 are rotatably connected to the inner wall of the surfboard 1. One end of the rotating rod 10 is fixedly connected to a bevel gear 11, and the other end of the rotating rod 10 is fixedly connected to two propellers 12. Two water spray frames 13 are installed on the inner wall of the other end of the surfboard 1. A connecting frame 14 is fixedly connected to the inner wall of the water spray frame 13. Two connecting rods 8 are rotatably connected to the inner wall of the surfboard 1. Both ends of the connecting rods 8 are fixedly connected to bevel gears 9. One end of the rotating shaft 5 is fixedly connected to a bevel gear 6. The two bevel gears 9 mesh with the tooth ends of the bevel gear 6, and the two bevel gears 9 mesh with the tooth ends of the bevel gear 11. The rotating rod... The other end of 10 is rotatably connected to the inner wall of the connecting frame 14. Two rubber rings 18 and the movable frame 17 are slidably connected to the inner wall of the surfboard 1. Rotating frame one 19 is rotatably connected to one end of rotating frame two 21. Multiple rotating frames one 19 and rotating frame two 21 are slidably connected to the bottom end of the surfboard 1. Rotating shaft 5 is rotatably connected to the inner wall of the surfboard 1. Blade 7 is installed at the air inlet of exhaust pipe 15. The exhaust outlet of exhaust pipe 15 is located above protective frame one 20. The connection between movable frame 17 and multiple rotating frames one 19 is located between protective frame two 22 and surfboard 1.

[0022] Specifically, the gas engine 4 drives the blades 7 to rotate via the rotating shaft 5, causing the blades 7 to draw outside air into the surfboard 1 through the vent 24 and intake pipe 23 for the use and heat dissipation of the gas engine 4. At the same time, the blades 7 also inject air from inside the surfboard 1 into the exhaust pipe 15, allowing the airflow to clean debris from the protective frame 20 through the exhaust port of the exhaust pipe 15. When there is too much seaweed or debris on the protective frame 20, the electric telescopic rod 16 is activated, causing the electric telescopic rod 16 to move the moving frame 17 and rubber ring 18 along the inner wall of the surfboard 1. The rubber ring 18 on the movable frame 17 can prevent seawater from contacting the electric telescopic rod 16. The movable frame 17 drives multiple rotating frames 21 and 19 to rotate via the electric telescopic rod 16. This causes the multiple rotating frames 21 and 19 to pull the seaweed or debris on the protective frame 20 downwards. The airflow and sea current from the exhaust pipe 15 can wash away the seaweed or debris on the rotating frames 19 and 21, thus cleaning the seaweed or debris on the protective frame 20 and preventing the bottom water inlet of the surfboard 1 from becoming clogged.

[0023] Please refer to Figures 3, 7, and 8. The steering assembly 25 includes a servo motor 2501, which is installed inside the surfboard 1. The output end of the servo motor 2501 is fixedly connected to a first synchronous pulley 2502. The tooth ends of the first synchronous pulley 2502 are meshed with two synchronous belts 2503. The inner wall of the surfboard 1 is rotatably connected to two second connecting rods 2504. The outer wall of the second connecting rods 2504 is fixedly connected to a second synchronous pulley 2505 and two gears 2506. The inner wall of the surfboard 1 is slidably connected to a moving plate 2507. The top end of the moving plate 2507 is fixedly connected to two racks 2508. The synchronous belts 2503 are meshed with the tooth ends of the second synchronous pulley 2505, and the two gears 2506 are meshed with the tooth ends of the racks 2508.

[0024] Specifically, the first synchronous pulley 2502 is connected to the second synchronous pulley 2505 via two synchronous belts 2503, and together with the second connecting rod 2504 on the second synchronous pulley 2505, it forms a transmission structure, enabling the servo motor 2501 to drive the gears 2506 on both sides to rotate simultaneously. Through the meshing of the gears 2506 with the rack 2508, the servo motor 2501 indirectly controls the moving plate 2507 to move left and right at the bottom of the surfboard 1, so that the moving plate 2507 can block one of the water inlets, allowing the other water jet frame 13 of the surfboard 1 to spray water, thereby facilitating the turning of the surfboard 1.

[0025] Please refer to Figures 1-8. S1: The user places the powered surfboard on the sea surface and stands on it. S2: The user controls the gas engine 4, electric telescopic rod 16, and servo motor 2501 through controller 2. The gas engine 4 controls the surfboard to move by pushing the components. The electric telescopic rod 16 cleans seaweed or debris on the protective frame 20 through the moving frame 17, rotating frame 19, and rotating frame 21. The servo motor 2501 moves the moving plate 2507 left and right at the bottom of the surfboard 1 through components such as synchronous pulley 2502, synchronous belt 2503, and synchronous pulley 2505. The moving plate 2507 can block one of the water inlets at the bottom of the surfboard 1, thus facilitating the surfboard's turning. S3: After surfing, the user holds the air inlet 23, places the powered surfboard on the support frame, and washes and maintains the powered surfboard for the next use.

[0026] Specifically, the user first places the powered surfboard on the ocean surface, then steps onto the surfboard from the shore, maintaining balance. The user then controls the gas engine 4, electric telescopic boom 16, and servo motor 2501 via controller 2. Gas engine 4 starts upon receiving a signal, propelling the surfboard forward on the sea surface via its rear propulsion assembly. Electric telescopic boom 16 pushes the moving frame 17, rotating frame one 19, and rotating frame two 21, clearing seaweed or other debris entangled on the protective frame one 20. Servo motor 2501 rotates as instructed, driving synchronous pulley one 2502, which transmits power via synchronous belt 2503 to synchronous pulley two 2505, driving the moving plate 2507 to move laterally under the surfboard 1. Moving plate 2507 covers a water inlet on the bottom of the surfboard 1, changing the water flow direction and assisting the surfboard in turning. After surfing, the user holds the air intake 23 and carries the entire surfing device to the shore, placing it on a dedicated support frame. Users thoroughly rinse the motorized surfboard to remove any remaining seawater and debris, and inspect and maintain all components to ensure the equipment is in good condition for the next use.

[0027] Working principle: The gas engine 4 drives the blades 7 to rotate via the rotating shaft 5, drawing in external air into the surfboard 1 for the gas engine's use and heat dissipation. Simultaneously, air is injected into the exhaust pipe 15, and the airflow is ejected from the exhaust port to clean debris from the protective frame 20. When there is too much debris, the electric telescopic rod 16 is activated, moving the movable frame 17 and rubber ring 18 along the inner wall of the surfboard. The rubber ring 18 prevents seawater from contacting the electric telescopic rod. The movable frame 17 drives the rotating frames 19 and 21 to rotate, pushing the debris on the protective frame 20 downwards. This allows the airflow from the exhaust pipe 15 and the ocean current to wash it away, preventing blockage of the inlet.

[0028] Synchronous pulley 2502 is connected to synchronous pulley 2505 via synchronous belt 2503. Servo motor 2501 drives gears 2506 on both sides to rotate. Gears 2506 mesh with rack 2508, controlling the moving plate 2507 to move left and right at the bottom of the surfboard, thereby blocking one water inlet and causing the other water jet 13 to spray water. The reaction force generated by the water jet on one side adjusts the turning angle of the surfboard. When the moving plate moves to the left and blocks the left water inlet, the water jet from the right water jet will generate a turning torque to the left, and vice versa, it will generate a turning torque to the right, thus facilitating the turning of the surfboard.

[0029] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
