Description

Technical Field

[0001] This application relates to a water sports tool, and more particularly to a pedal boat. Background Technology

[0002] Existing pedal boats rely on human power to drive a propeller mounted under the stern through a pedal mechanism. This traditional method of propulsion results in high water resistance, requires strenuous pedaling, and is slow. In addition, the propeller is easily corroded due to prolonged immersion in water. Summary of the Invention

[0003] The purpose of this application is to solve the problems in the prior art where the propeller is installed at the lower part of the stern, resulting in high water resistance during forward movement, requiring significant effort to pedal and resulting in slow speed. Furthermore, the propeller is prone to corrosion due to prolonged immersion in water. This application provides a water-based pedal boat that solves the problems of difficult pedaling, slow speed, and easy corrosion of the propeller.

[0004] This application provides a pedal boat, including a hull, a pedal power mechanism disposed inside the hull, and a propulsion device disposed on at least one side of the hull. The pedal power mechanism and the propulsion device are connected by transmission. The pedal power mechanism includes a foot pedal and a chainring coaxially disposed with the foot pedal. The propulsion device includes a drive wheel and two symmetrical discs, which are coaxially disposed with the drive wheel and the two discs. Each of the two discs is connected to at least one paddle. The propulsion device is kept in a non-contact state with the water surface.

[0005] In some embodiments, the propulsion device further includes a support rod with an axle mounted on its lower part and a movable rod mounted on its upper part. A power wheel and two discs are mounted on the axle. At least two annular connectors are provided on the movable rod, and the propeller shank passes through the inner hole of the annular connector, allowing the propeller to slide axially.

[0006] In some embodiments, the movable rod is movably connected to the support rod, and each propeller handle passes through the inner hole of at least one annular connector, allowing the propeller to slide flexibly in the axial direction while limiting the lateral displacement of the propeller handle to suppress paddling vibration.

[0007] In some embodiments, the propeller is detachably mounted on a mounting ring with the center of the disc as the origin and a radial distance of 0.5RR, where R is the radius of the disc. The position of the propeller blade can be adjusted to adapt to different working conditions.

[0008] In some embodiments, the chainring and the drive wheel are connected by a transmission device. The foot pedal drives the chainring, which is coaxial with it, to rotate through mechanical movement. The chainring transmits power to the drive wheel through the transmission device. The drive wheel drives the disc to rotate, which in turn drives the oar on the disc to paddle in the water.

[0009] In some embodiments, the transmission device is a hinge transmission.

[0010] In some embodiments, the number of teeth on the chainring is 98, and the number of teeth on the drive wheel is 36.

[0011] In some embodiments, the hull also includes a seat positioned above the foot-operated power mechanism.

[0012] This application provides a water-based pedal boat where the propulsion device remains in a non-contact state with the water surface. The propulsion is achieved by rotating a disc, which drives the paddles to move through the water, replacing the traditional immersion-type working mode of a propeller. This significantly reduces the risk of corrosion, as the disc does not contact the water and the paddles only briefly come into contact with the water during the stroke cycle. A movable rod connects the paddles, with at least one annular connector passing through the paddle handle, improving the axial sliding flexibility of the paddles while limiting the lateral displacement of the paddle handle to suppress stroke vibration and improve stability. The handle and disc are detachably connected, and the installation position is adjustable to adapt to different working conditions. The combination of the chainring and the drive wheel results in a large transmission ratio, making pedaling easier and improving propulsion efficiency. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0021] Please see Figure 1 , Figure 1 This is a schematic diagram of a water bicycle.

[0022] like Figure 1 As shown, this application provides a water-based pedal bicycle, which includes a hull 1, a pedal power mechanism 2 disposed inside the hull 1, and a propulsion device 3 disposed on at least one side of the hull 1. The pedal power mechanism 2 and the propulsion device 3 are connected by a transmission. The pedal power mechanism 2 includes a pedal 4 and a chainring 5 coaxially disposed with the pedal 4. The propulsion device 3 includes a drive wheel 6 and two symmetrical discs 7, which are coaxially disposed. Each of the two discs 7 is connected to at least one paddle 8. The propulsion device 3 is kept in a non-contact state with the water surface to reduce the risk of corrosion.

[0023] In this embodiment, the propulsion device 3 further includes a support rod 10. A wheel axle 11 is mounted on the lower part of the support rod 10, and the wheel axle 11 can rotate relative to the support rod 10. A movable rod 12 is mounted on the upper part. The power wheel 6 and two discs 7 are disposed on the wheel axle 11. At least one annular connector 13 is provided at each end of the movable rod 12. The handle 9 of the paddle 8 can pass through the inner hole of one annular connector 13 or simultaneously through the inner holes of multiple annular connectors 13. When the discs 7 rotate, the inner holes of the annular connectors 13 of the paddle 8 slide axially. Passing through the inner holes of multiple annular connectors 13 can limit the lateral displacement of the handle 9 to suppress paddling vibration and improve stability.

[0024] In this embodiment, the movable rod 12 is movably connected to the support rod 10, allowing the paddle 8 to slide flexibly along the axial direction.

[0025] In this embodiment, the paddle 8 is detachably mounted on a mounting ring with the center of the disc 7 as the origin and a radial distance of 0.5RR, where R is the radius of the disc 7. When driving the pedal boat and wanting to propel it slowly, the paddle 8 can be positioned within the mounting ring close to 0.5R. When wanting to propel it quickly, the paddle 8 can be positioned within the mounting ring close to R. By adjusting the position of the paddle blade, different working conditions can be adapted.

[0026] like Figure 1 As shown in the embodiment of this application, the chainring 5 and the drive wheel 6 are connected by a hinge. The foot pedal 4 drives the chainring 5, which is coaxial with it, to rotate through mechanical movement. The chainring 5 transmits power to the drive wheel 6 through the hinge. The drive wheel 6 drives the disc 7 to rotate, which in turn drives the oar 8 on the disc 7 to paddle in the water. It should be noted that although... Figure 1 The chainring 5 and drive wheel 6 shown are connected by a hinge drive, but any other drive assembly capable of transmitting power (such as belts, shaft drives, etc.) can also be used.

[0027] In this embodiment, the chainring 5 has 98 teeth, the drive wheel 6 has 36 teeth, and the transmission ratio is approximately 2.72:1. The high transmission ratio optimizes pedaling efficiency and is suitable for high-speed propulsion.

[0028] In this embodiment, the hull 1 also includes a seat 15, which is disposed above the foot pedal power mechanism 2.

[0029] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application. Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
