Description

Technical Field

[0001] This utility model relates to the field of sports equipment technology, and in particular to a powered surfboard with an adjustable propulsion device. Background Technology

[0002] The surfboard is the core tool of surfing, providing surfers with support and balance, enabling them to glide, turn, and perform other maneuvers using the power of the waves. It serves as a medium for humanity to challenge nature and engage with the waves, allowing people to experience speed and freedom while conquering them; it also acts as a link between humanity and nature, driving the development of surfing culture and giving rise to diverse forms such as competitive and recreational surfing. Furthermore, it conveys reverence and love for the ocean, becoming a symbol of courage and exploration.

[0003] Powered surfboards use a built-in motor to drive a propeller or water jet propulsion system, generating thrust to propel the board across the water. The control handles adjust power and direction, and the board's streamlined design reduces drag. They have a wide range of applications, including water recreation and extreme sports performances in open seas and lakes, as well as professional scenarios such as coastal patrols and water rescue. They can also serve as a means of transportation, allowing users to experience the thrill of surfing even when there are no waves, combining entertainment and practicality.

[0004] In existing technologies, some powered surfboards rely solely on an electric motor to drive a propeller or water jet propulsion system. This makes it difficult to adjust the angle of the propeller or water jet, hindering surfers' ability to flexibly change the surfboard's direction and respond quickly and accurately to changes in motion. This reduces the surfboard's maneuverability and makes it difficult to adjust the propulsion angle to control the surfboard's posture under varying wave conditions and speeds, compromising balance and increasing the risk of fall into the water. Therefore, this paper proposes a powered surfboard with an adjustable propulsion system to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a powered surfboard with an adjustable propulsion device, aiming to improve the problem that some existing powered surfboards only rely on motors to drive propellers or water jets for power, making it difficult to adjust the angle of the propellers or water jets, which makes it difficult for surfers to flexibly change the direction of the surfboard and to respond quickly and accurately to the surfer's changing needs for movement.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A powered surfboard with an adjustable propulsion device includes a surfboard and a mounting box. A rotating motor is fixedly connected to the inner wall of the mounting box, and a worm gear is fixedly connected to the drive end of the rotating motor. A worm wheel is rotatably connected to the inner wall of the mounting box. The outer wall of the worm gear and the outer wall of the worm wheel are meshed with each other. A controller is rotatably connected to the inner wall of the mounting box, and a control rod is rotatably connected to the bottom of the worm wheel. A mounting assembly for mounting is fixedly connected to the bottom of the surfboard.

[0008] As a further description of the above technical solution:

[0009] The mounting assembly includes a mounting plate, a dovetail plate slidably connected to the bottom of the mounting plate, a fixing plate detachably connected to the outer wall of the mounting plate, and a plug-in plate fixedly connected to the inner wall of the fixing plate.

[0010] As a further description of the above technical solution:

[0011] The outer wall of the plug plate is detachably connected to the inner wall of the mounting plate, and the outer wall of the plug plate is detachably connected to the inner wall of the dovetail plate.

[0012] As a further description of the above technical solution:

[0013] The inner wall of the fixing plate is threaded with two fixing screws, and the outer walls of the two fixing screws are threaded to the inner wall of the mounting plate.

[0014] As a further description of the above technical solution:

[0015] The top of the mounting box is detachably connected to the bottom of the dovetail plate, and a connecting plate is fixedly connected to the outer wall of the mounting box;

[0016] As a further description of the above technical solution:

[0017] The other end of the control lever is rotatably connected to the top of the controller, and a sealing plate is rotatably connected to the bottom of the controller. The outer wall of the sealing plate is slidably connected to the inner wall of the mounting box.

[0018] As a further description of the above technical solution:

[0019] A connecting rod is fixedly connected to the bottom of the sealing plate, and a drive motor is fixedly connected to the bottom of the connecting rod.

[0020] As a further description of the above technical solution:

[0021] A rotating column is rotatably connected to the bottom of the connecting plate, a fixed rod is rotatably connected to the bottom of the rotating column, the bottom of the fixed rod is fixedly connected to the top of the drive motor, and a pusher is fixedly connected to the drive end of the drive motor.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, a rotating motor drives a worm gear to rotate, which in turn drives a meshing worm wheel to rotate. The rotation of the worm wheel drives a control rod to move, which in turn causes a sealing plate connected to one end of the controller to swing left and right. This causes the bottom of the sealing plate to move the connecting rod left and right. By controlling the rotation of the column, the angle of the thruster can be adjusted left and right. By changing the thruster's spray angle, the direction of the surfboard's movement can be controlled, allowing the surfer to better adapt to different movement needs and adjust the surfboard's posture and maintain balance by adjusting the thrust angle.

[0024] 2. In this utility model, rotating the fixing screws removes the fixing plate from the mounting plate. At this point, the plug-in plate is pulled out of the mounting plate and the dovetail plate. Since the plug-in plate does not limit the mounting plate and the dovetail plate, the dovetail plate is pulled out of the inner wall of the mounting plate, thus completing the disassembly of the pusher and the mounting box.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 2 to 4 This utility model provides an embodiment of a powered surfboard 1 with an adjustable propulsion device, comprising a surfboard 1 and a mounting box 9. The mounting box 9 is used to accommodate internal components such as a rotating motor 16 to ensure their normal operation. The rotating motor 16 is fixedly connected to the inner wall of the mounting box 9. The rotating motor 16 serves as a power source and can output rotational power after being powered on. A worm gear 15 is fixedly connected to the drive end of the rotating motor 16. The worm gear 15 rotates synchronously with the drive end of the rotating motor 16. A worm wheel 10 is rotatably connected to the inner wall of the mounting box 9. The worm wheel 10 can rotate within the inner wall of the mounting box 9. The outer wall of the worm gear 15 and the outer wall of the worm wheel 10 are meshed together, and the power transmission from the worm gear 15 to the worm wheel 10 is achieved through this meshing connection.

[0035] A controller 11 is rotatably connected to the inner wall of the mounting box 9. The controller 11 can rotate within the inner wall of the mounting box 9 to drive the movement of subsequent components. A control rod 12 is rotatably connected to the bottom of the worm gear 10. One end of the control rod 12 moves with the rotation of the worm gear 10. A mounting assembly for installation is fixedly connected to the bottom of the surfboard 1. The mounting assembly is used to achieve a detachable connection between the mounting box 9 and the surfboard 1. The other end of the control rod 12 is rotatably connected to the top of the controller 11. The control rod 12 converts the rotation of the worm gear 10 into the swinging motion of the controller 11 through the rotatable connection at both ends. A sealing plate 13 is rotatably connected to the bottom of the controller 11. The sealing plate 13 can swing with the movement of the controller 11.

[0036] The outer wall of the sealing plate 13 is slidably connected to the inner wall of the mounting box 9. The sealing plate 13 achieves stable swinging and prevents water from entering by sliding to the inner wall of the mounting box 9. A connecting rod 14 is fixedly connected to the bottom of the sealing plate 13. The connecting rod 14 moves with the swinging of the sealing plate 13. A drive motor 2 is fixedly connected to the bottom of the connecting rod 14. The drive motor 2 is used to drive the propeller 3 to rotate. A rotating column 18 is rotatably connected to the bottom of the connecting plate 17. The rotating column 18 can limit the movement direction of the connecting rod 14 and allow it to swing. A fixed rod 19 is rotatably connected to the bottom of the rotating column 18. The fixed rod 19 is used to connect the rotating column 18 and the drive motor 2. The bottom of the fixed rod 19 is fixedly connected to the top of the drive motor 2. The drive motor 2 is connected to the rotating column 18 through the fixed rod 19. A propeller 3 is fixedly connected to the drive end of the drive motor 2. The propeller 3 rotates under the drive of the drive motor 2 and changes the movement direction of the surfboard 1 by adjusting the angle.

[0037] Reference Figure 1 , Figure 5 and Figure 6 The installation components include an installation plate 4, which is fixed to the bottom of the surfboard 1 as an installation base. A dovetail plate 5 is slidably connected to the bottom of the installation plate 4. The dovetail plate 5 can slide on the bottom of the installation plate 4 to achieve installation or removal. A fixing plate 6 is detachably connected to the outer wall of the installation plate 4. The fixing plate 6 achieves the fixing and release of the plug-in plate 8 through a detachable connection. The plug-in plate 8 is fixedly connected to the inner wall of the fixing plate 6. The plug-in plate 8 is used to insert the installation plate 4 and the dovetail plate 5 to achieve limiting. Two fixing screws 7 are threadedly connected to the inner wall of the fixing plate 6. The fixing screws 7 fix the fixing plate 6 to the outer wall of the installation plate 4 through threaded connection.

[0038] The outer walls of the two fixing screws 7 are threaded to the inner wall of the mounting plate 4. The two fixing screws 7 enhance the stability of the fixation. The top of the mounting box 9 is detachably connected to the bottom of the dovetail plate 5. The mounting box 9 is connected to the mounting assembly through the dovetail plate 5. The outer wall of the mounting box 9 is fixedly connected to the connecting plate 17, which is used to connect the mounting box 9 and the rotating column 18 to transmit movement.

[0039] Working principle: When the angle of the thruster 3 needs to be adjusted, the rotating motor 16 starts and drives the worm gear 15 to rotate. The rotation of the worm gear 15 drives the worm wheel 10 to rotate. The rotation of the worm wheel 10 drives the control rod 12 to move. The movement of the control rod 12 drives one end of the controller 11 to swing left and right. This causes the sealing plate 13 connected to one end of the controller 11 to swing left and right. This causes the bottom of the sealing plate 13 to drive the connecting rod 14 to move left and right. By limiting the rotation of the column 18, the angle of the thruster 3 is adjusted left and right. Thus, by changing the direction of movement of the thruster 3, the direction of movement of the surfboard 1 is controlled.

[0040] When it is necessary to disassemble the thruster 3 and the mounting box 9, turn the fixing screw 7 so that there is nothing to fix the fixing plate 6 and the mounting plate 4. Then, pull the plug plate 8 out of the mounting plate 4 and the dovetail plate 5. Since the mounting plate 4 and the dovetail plate 5 are no longer restrained by the plug plate 8, pull the dovetail plate 5 out of the inner wall of the mounting plate 4. At this time, the dovetail plate 5, along with the mounting box 9 and the thruster 3, is removed from the interior of the mounting plate 4, and the disassembly of the mounting box 9 and the thruster 3 is completed.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
