Therefore, they should not be construed as limitations on the present invention.

[0020] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0021] Example:

[0022] The purpose of this embodiment is to provide a scooter where the user stands on the panel and propels the scooter forward by changing their center of gravity in the forward and backward directions. This enhances the fun of using the scooter, solves the problem of users having to repeatedly get on and off the scooter, and achieves the technical objectives of reducing fatigue and making it easy to use.

[0023] A scooter includes a frame and a deck. The frame includes a first cantilever 13, a second cantilever 14, and a connecting portion 15; the first cantilever 13 and the second cantilever 14 are connected, and the connecting portion 15 is provided at the connection point. A rear wheel 16 is provided on the first cantilever 13, and a front wheel 17 assembly is provided on the second cantilever 14. The front wheel 17 assembly includes a front wheel 17. The deck includes a first deck 11 and a second deck 12, which are rotatably connected.

[0024] A drive mechanism is installed on the frame. The drive mechanism includes a drive shaft 20 and a driven shaft 24; the panel is connected to the drive shaft 20. The panel drives the drive shaft to rotate; the drive shaft drives the driven shaft to rotate unidirectionally through a transmission component, and the driven shaft drives the rear wheel to rotate.

[0025] The transmission components include a first transmission component. The first transmission component includes a first drive wheel and a first driven wheel. A first drive wheel 211 is mounted on the drive shaft 20; the panel drives the first drive wheel 211 to rotate via the drive shaft 20. Preferably, the first cantilever 13, the second cantilever 14, and the connecting part 15 form a triangular structure, with the connecting part 15 located at the top; the panel forms a seesaw structure with the frame via the drive shaft 20, and when the user stands on the panel, their center of gravity shifts repeatedly on both sides of the drive shaft 20, causing the panel to swing up and down, thus rotating the drive shaft 20. The first drive wheel 211 is fixedly connected to the drive shaft 20, therefore, the first drive wheel 211 can rotate synchronously with the drive shaft 20. Optionally, the drive shaft 20 is fixedly inserted into the bearing of the connecting part 15 and can rotate freely, that is, the outer ring of the bearing is fixedly connected to the connecting part, and the inner ring is fixedly connected to the drive shaft. The first plate 11 is fixedly connected to the drive shaft 20 through a keyway or flange structure, that is, the first plate is connected to both ends of the drive shaft, so that the up and down swing of the first plate 11 can directly drive the drive shaft 20 to rotate.

[0026] The driven shaft is mounted on the first cantilever 13, and the rear wheel 16 is mounted on the driven shaft. A first driven wheel is also mounted on the driven shaft. The first drive wheel 211 drives the first driven wheel 216 to rotate via a first transmission element. The first driven wheel drives the driven shaft to rotate in one direction, and the driven shaft drives the rear wheel 16 to rotate. The first driven wheel 216 drives the driven shaft to rotate in one direction, and when the driven wheel rotates in the opposite direction, the driven shaft is in a free-spinning state, achieving unidirectional power output without affecting the reverse rotation of the driven shaft and the rear wheel 16.

[0027] In one possible embodiment, to enable the scooter to receive unidirectional power from the scooter by stepping on the skateboard, at least one of the first drive wheel 211 and the first driven wheel is a unidirectional wheel. For example, when the drive shaft 20 rotates clockwise, the first drive wheel 211 and / or the first driven wheel rotates in one direction, driving the rear wheel 16 to rotate, thus propelling the scooter forward. When the drive shaft 20 rotates counterclockwise, the first drive wheel 211 and / or the first driven wheel is in an idle state, not affecting the rotation of the rear wheel 16 itself, and not affecting the movement of the scooter. Similarly, when the driven shaft rotates in the opposite direction, the first drive wheel 211 and / or the first driven wheel is also in an idle state, without affecting the user's experience. Optionally, the unidirectional wheel can be a ratchet, a unidirectional helical gear, or a unidirectional synchronous belt pulley, and the first transmission element can be a chain, a gear shaft, or a synchronous belt; their selection and connection methods are common technical solutions for those skilled in the art and will not be described in detail here.

[0028] To achieve better forward movement when stepping on the pedal panel, in this embodiment, the first transmission component further includes a first transmission shaft 212 and a first transmission wheel 213. A transmission rod 23 is mounted on the frame, and the first transmission shaft 212 and the first transmission wheel 213 are coaxially mounted on the transmission rod 23 via bearings. The first transmission shaft is a hollow shaft. The connection between the first transmission shaft 212 and the first transmission wheel 213 allows for synchronous rotation on the transmission rod 23. The diameter of the first transmission shaft 212 is smaller than that of the first drive wheel 211 and the first transmission wheel 213; the first transmission shaft 212 engages with the first drive wheel 211. Due to the synchronous rotation of the first transmission shaft 212 and the first transmission wheel 213, the aforementioned mechanism allows for a smaller linear velocity input to the first drive wheel 211 and a larger linear velocity output to the first transmission wheel 213. The first drive wheel 213 is connected to the first driven wheel via the first transmission element 214. In this embodiment, the first drive wheel 211 is a gear, the first transmission shaft 212 is a gear shaft, and the first drive wheel 211 meshes with the first transmission shaft 212. Both the first drive wheel 213 and the first driven wheel are synchronous wheels, and the first transmission element 214 is a synchronous belt. The first drive wheel 211 drives the first drive wheel 213 to rotate via the first transmission shaft 212, and the first drive wheel 213 drives the first driven wheel to rotate via the first transmission element 214. Preferably, the diameter of the first driven wheel is smaller than that of the first drive wheel 213, and the linear velocity input to the first drive wheel can be amplified in two stages, allowing the scooter user to generate a longer gliding distance with slight movements. In other possible embodiments, in order to achieve the effect of unidirectional power output after pedaling, at least one of the first drive wheel 211, the first drive wheel 213, and the first driven wheel is a unidirectional wheel; its principle, selection, and effect will not be elaborated further.

[0029] To achieve forward movement by shifting the panel's center of gravity forward and backward, this embodiment includes a second transmission component. The second transmission component comprises a second drive wheel and a second driven wheel. A second drive wheel 221 is mounted on the drive shaft 20; a second driven wheel is mounted on the driven shaft; the second drive wheel 221 drives the second driven wheel to rotate via a second transmission component, and the second driven wheel drives the driven shaft to rotate in one direction; the second transmission component also includes a reversing shaft 226, a second transmission shaft 222, a second transmission wheel 223, and a second transmission element 224; the reversing shaft is mounted on the frame; the second transmission shaft is a hollow shaft; the second transmission shaft 222 and the second transmission wheel 223 are coaxially mounted on the transmission rod 23 via bearings; the second transmission shaft 222 and the second transmission wheel 223 can rotate synchronously on the transmission rod 23; the reversing shaft cooperates with the second drive wheel 221 and the second transmission shaft 222; the second drive wheel 221 drives the reversing shaft to rotate; the reversing shaft drives the second transmission shaft 222 to rotate, and the second transmission shaft drives the second transmission wheel 223 to rotate; the second transmission wheel 223 drives the second driven wheel to rotate via the second transmission element 224. The reversing shaft is mounted on the reversing rod of the frame and can rotate independently. The second transmission component operates on the same principle as the first transmission component, and the selection of parts and its operating principle will not be repeated here. The difference lies in the introduction of a reversing shaft 226 in the second transmission component. The second drive wheel 221 indirectly drives the second transmission shaft 222 to rotate through the reversing shaft. When the user shifts their center of gravity forward or backward, either the first driven wheel or the second driven wheel can provide unidirectional power output to the driven shaft.

[0030] This embodiment also provides a specific structure for unidirectional power output, used to achieve unidirectional rotation of the driven shaft. A first driven wheel is sleeved on the driven shaft; a first one-way bearing 215 is also provided on the driven shaft; the outer ring of the first one-way bearing 215 is connected to the first driven wheel; the inner ring of the first one-way bearing 215 is connected to the driven shaft; a second driven wheel is sleeved on the driven shaft; a second one-way bearing 225 is also provided on the driven shaft; the outer ring of the second one-way bearing 225 is fixedly connected to the second driven wheel; the inner ring of the first one-way bearing 215 is fixedly connected to the driven shaft. This mechanism employs a one-way bearing. A one-way bearing, also often called an overrunning clutch, has the core characteristic of transmitting torque only in one direction of rotation, while it will idle (slip) in the opposite direction. The first and second driven wheels are not directly fixed to the driven shaft, but are sleeved on the driven shaft via bearings; preferably, they are sleeved on the driven shaft via bearing sleeves. When the first driven wheel or the second driven wheel is driven to rotate in the "driving direction", the one-way bearing locks, thereby transmitting torque to the driven shaft and driving the rear wheel 16 forward. When the first driven wheel or the second driven wheel rotates in the opposite direction, the one-way bearing is in an idle state, the driven shaft and the rear wheel 16 do not receive reverse power, and can continue to roll forward by inertia. Based on the specific structure of unidirectional power output given in this embodiment, an optional first transmission component and a second transmission component are provided; the first transmission element and the second transmission element are transmission rods, the two ends of the transmission rods are bevel gears, and the first transmission wheel, the second transmission wheel, the first driven wheel and the second driven wheel are bevel gears. Based on the specific structure of unidirectional power output given in this embodiment, an optional first transmission component and a second transmission component are also provided; the first transmission element and the second transmission element are synchronous belts, and the first transmission wheel, the second transmission wheel, the first driven wheel and the second driven wheel are synchronous pulleys. Based on the specific structure of unidirectional power output given in this embodiment, an optional first transmission component and second transmission component are also provided; the first transmission element and the second transmission element are chains, and the first transmission wheel, the second transmission wheel, the first driven wheel and the second driven wheel are sprockets.

[0031] To achieve the steering effect, in this embodiment, the second cantilever 14 is rotatably connected to the front wheel 17 assembly; the panel includes a first panel and a second panel; the first panel and the second panel are rotatably connected; the second panel is connected to the front wheel 17 assembly via a steering mechanism; the steering mechanism includes a steering shaft 32, which is mounted on the second cantilever 14 and can rotate relative to the second cantilever 14 around its own axis; the two ends of the steering shaft 32 are respectively connected to a steering plate 31 and a steering lever 33; the steering plate 31 cooperates with the second panel 12 to achieve clockwise or counterclockwise rotation of the steering plate 31 around the steering shaft 32, thereby driving the steering shaft 32 to rotate clockwise or counterclockwise. A steering rod 34 is provided on the front wheel 17 assembly; the steering lever 33 drives the front wheel 17 assembly to rotate relative to the second cantilever 14 via the steering rod 34. The steering shaft 32 drives the steering lever 33 to swing left and right, and the steering lever 33 drives the steering rod 34 to swing left and right. The front wheel assembly 17 is rotatably connected to the second cantilever 14, causing the front wheel assembly 17 to swing left and right when the steering lever 34 swings, thereby changing direction. The user's center of gravity will not fall off the scooter, greatly increasing safety.

[0032] Preferably, the steering lever 34 is provided with a ball socket 341, and a spherical sleeve is provided inside the ball socket 341. The spherical sleeve has a shaft hole 341. The spherical sleeve is fitted onto the steering lever 33 through the shaft hole 341. The ball socket 341 restricts the spherical sleeve within the ball socket 341, forming a steering joint structure. The steering lever 33 swings left and right, and the steering joint structure achieves smooth force transmission, reducing friction between parts.

[0033] To conserve user energy, in this embodiment, the drive shaft 20 is disposed at the connecting portion 15; the first panel 11 is connected to the drive shaft 20; and a first spring 51 is disposed between the first panel 11 and the first cantilever 13. The first spring 51 is used to help the user reset the panel after stepping on the first panel 11, thus saving energy. The first spring includes at least one spring.

[0034] Preferably, in this embodiment, a spring assembly 52 is provided between the steering plate 31 and the second panel 12; the spring assembly 52 includes two return springs, which are respectively located on both sides of the steering shaft 32. The spring assembly 52 serves two purposes: firstly, it helps the user reset the second panel 12 after stepping on it; secondly, it transmits the force of the second panel 12 to both ends of the steering plate 31 through the two return springs, thus achieving the rotation of the steering plate 31. Specifically, when the user applies force to both sides of the second panel 12, the second panel 12 will rotate relative to the first panel 11, and one side of the second panel 12 will apply a larger force to the steering plate 31, causing it to rotate. Optionally, the spring assembly can contain one or more springs. The spring assembly achieves the combined function of resetting the panel and steering.

[0035] In this embodiment, the scooter further includes a braking assembly; the braking assembly includes a brake crank and a brake spring 42; the brake crank is hinged to the first cantilever 13; one end of the brake spring 42 is connected to the first cantilever 13, and the other end is connected to the brake crank; the brake crank includes a force-receiving part 411 and a braking part 412; a brake wheel 43 is provided on the driven shaft; the brake wheel 43 cooperates with the brake part 412. In this embodiment, the brake spring 42 is located near the brake part 412 at the hinge of the brake crank. When the force-receiving part 411 is not under force, the brake spring 42 is compressed, and the brake part 412 moves away from the brake wheel 43; when the force-receiving part 411 is under force, the brake part 412 moves closer to the brake wheel 43, and the driven shaft is decelerated by friction, achieving a braking effect. Before getting on the scooter, the rider can step on the brake, meaning the scooter is in a stable state before the rider gets on, making it easier to get on and less likely to fall. During gliding, the rider can slow down and stop the scooter by pushing or stepping on it with their back foot, improving operability and safety.

[0036] In this embodiment, to facilitate use of the scooter by beginners, a limiting screw 53 is also provided on the frame. The limiting screw 53 includes an adjusting part 532 and a limiting part 531. The adjusting part 532 is threaded into the frame. The limiting part 531 is located at the top of the adjusting part 532 and engages with the panel. The limiting part 531 limits the range of vertical swing of the panel, thereby limiting the power input of the drive shaft 20 and preventing injury to the user due to excessive speed. The distance between the limiting part 531 and the panel can be changed by rotating the limiting screw 53. Preferably, limiting screws 53 are respectively provided on the first cantilever 13 and the second cantilever 14, and engage with the first panel 11 and the second panel 12 respectively.

[0037] The method of using the scooter provided in this embodiment is as follows: The user stands with both feet on the dashboard of the scooter; The panel swings up and down by alternating the shift of the body's center of gravity in the forward and backward direction of the drive shaft. The up-and-down swing is converted into the reciprocating rotational motion of the drive shaft; The drive shaft drives the driven shaft to rotate in one direction through the transmission components, converting the rotation of the drive shaft into the rotation of the driven shaft in one direction, which in turn drives the rear wheel to rotate.

[0038] The beneficial technical effects of this embodiment are as follows: By setting a transmission wheel set with a specific transmission ratio (for example, the diameter of the first transmission shaft 212 is smaller than that of the first drive wheel 211), the user's small shift in center of gravity is amplified into a larger rotation angle of the rear wheel, achieving labor-saving and efficient driving. At the same time, the user's feet never leave the panel and do not contact the ground, significantly reducing the risk of falls due to pushing off the ground or loss of balance, making it especially suitable for beginners and children.

[0039] In other possible embodiments, the first transmission element 214 and the second transmission element 224 can be a synchronous belt, chain, or gear set. Considering cost, noise, and weight, a synchronous belt is the preferred option. The mechanism for achieving unidirectional rotation can also employ unidirectional transmission methods known in the art, such as a ratchet mechanism, in addition to a one-way bearing. The stiffness coefficient of the first spring 51 should ensure that the panel remains horizontal when no one is standing on it, while providing sufficient rebound force when bearing the user's weight.

[0040] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
