Implementation

[0008] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0009] It should be noted that, in the following embodiments, the novel skateboard of the present invention is indicated by reference numeral 100 in the accompanying drawings. Example 1

[0010] like Figure 1 , Figure 2, Figure 3 and Figure 4 As shown. The new skateboard 100 includes two pedals, namely a front pedal 1 and a rear pedal 2.

[0011] The novel skateboard 100 includes support arms, which are in two sets: a front support arm 3 and a rear support arm 4. The upper end of the front support arm 3 is connected to the front pedal 1, and the upper end of the rear support arm 4 is connected to the rear pedal 2. In this embodiment, there are three front support arms 3 forming one set, and three rear support arms 4 forming another set.

[0012] The new skateboard 100 includes a base 5. A first hinge bracket 6 is provided at the middle of the upper surface of the base 5. The lower ends of the front support arm 3 and the rear support arm 4 are hinged to the first hinge bracket 6 by a first bolt 7, that is, the lower ends of the front support arm 3 and the rear support arm 4 are hinged to the base 5. One lower end of the front support arm 3 and one lower end of the rear support arm 4 are fixedly connected. The front support arm 3 and the rear support arm 4 can rotate around the first bolt 7, so the front pedal 1 and the rear pedal 2 can move up and down.

[0013] A second hinge bracket 23 is fixed to the bottom of the front pedal 1 and the rear pedal 2. The upper ends of the three front support arms 3 and the three rear support arms 4 are hinged to the second hinge bracket 23 by a second bolt 24, that is, the upper ends of the front support arms are hinged to the front pedal, and the upper ends of the rear support arms are hinged to the rear pedal. When the front pedal 1 and the rear pedal 2 move up and down, the lower ends of the front support arms 3 and the lower ends of the rear support arms 4 rotate around the first bolt 7, while the upper ends of the front support arms 3 and the upper ends of the rear support arms 4 rotate around the second bolt 24. Therefore, the upper surfaces of the front pedal 1 and the rear pedal 2 can always remain horizontal. Figure 5 As shown, the upper surfaces of the front pedal 1 and the rear pedal 2 remain horizontal during vertical movement, ensuring good stability and safety.

[0014] The novel skateboard 100 includes a front wheel assembly. The front wheel assembly is located at the front end of the base 5 and includes front wheels 8 and front axles 9. In this embodiment, there are two front wheels 8. The novel skateboard 100 includes a steering mechanism. In this embodiment, the steering mechanism includes a horizontal rotating bracket 10, a base plate 11, and ball bearings (not shown). The front wheels 8, front axles 9, horizontal rotating bracket 10, base plate 11, and ball bearings (not shown) together constitute a swivel wheel. Swivel wheels are existing technology. The horizontal rotating bracket 10 has the front axles 9 passing through it, and each end of the front axle 9 is connected to a front wheel 8. The base plate 11 is fixed to the bottom front end of the base 5. The horizontal rotating bracket 10 is rotatably connected to the base plate 11, and ball bearings (not shown) are provided between the horizontal rotating bracket 10 and the base plate 11. The horizontal rotating bracket 10 can rotate 360 ​​degrees horizontally. When the horizontal rotating bracket 10 rotates, the front wheels 8 turn. The base plate 11 is also equipped with two limiting screws 12. The limiting screws 12 ensure that the horizontal rotating bracket 10 can only rotate within a certain angle range, such as within a 90-degree range. The limiting screws 12 can prevent the horizontal rotating bracket 10 from rotating randomly and can better control the steering of the front wheel 8. When the new skateboard 100 needs to turn while gliding forward, the foot on the front pedal 1 and the body slightly swing left or right, the horizontal rotating bracket 10 rotates, and the front wheel 8 turns.

[0015] The new skateboard 100 includes a rear wheel assembly. The rear wheel assembly is located at the rear end of the base 5. The rear wheel assembly includes a rear wheel 13 and a rear wheel axle 14. In this embodiment, there are two rear wheels 13. The two ends of the rear wheel axle 14 are fixedly connected to the two rear wheels 13.

[0016] The novel skateboard 100 includes a transmission mechanism. In this embodiment, the transmission mechanism includes a cable transmission mechanism, which comprises a cable 15, a guide pulley, a winding wheel, and a one-way clutch. The two ends of the cable 15 are connected to the front pedal 1 and the rear pedal 2, respectively. A first guide pulley 16 is provided at the bottom of the base 5, and a second guide pulley 17 is provided at the front end of the base 5. The one-way clutch uses a one-way bearing. Two one-way bearings are fixed on the rear wheel axle 14, including a first one-way bearing 18 and a second one-way bearing 19, and the one-way rotation directions of the first one-way bearing 18 and the second one-way bearing 19 are the same. A first winding wheel 20 is fixedly connected to the outer ring of the first one-way bearing 18, and a second winding wheel 21 is fixedly connected to the outer ring of the second one-way bearing 19. One end of the pull cable 15 is fixed to the bottom of the rear pedal 2, then wound several times on the first winding wheel 20 before being led out and connected to the first guide pulley 16. After being guided by the first guide pulley 16, it returns to the second winding wheel 21, wound several times before being led out and connected to the second guide pulley 17. After being guided by the second guide pulley 17, the other end of the pull cable 15 is fixed to the bottom of the front pedal 1. The novel skateboard 100 of this embodiment adopts a rear wheel 13 drive method.

[0017] The novel skateboard 100 includes an anti-slip mechanism. The front pedal 1 and the rear pedal 2 are equipped with the anti-slip mechanism, which makes it difficult for the feet to slip. In this embodiment, the anti-slip mechanism is a guard edge 22. The upper surface edges of the front pedal 1 and the rear pedal 2 are provided with raised guard edges 22, which can prevent the feet from slipping.

[0018] The main body of the new skateboard 100, including the front pedal 1, rear pedal 2, front support arm 3, rear support arm 4, and base 5, is made of aluminum alloy. The front wheel 8 and rear wheel 13 are made of highly elastic PU (polyurethane) wheels.

[0019] The operating principle of the new skateboard 100: The player stands sideways with both feet on the front pedal 1 and the rear pedal 2, the same stance as existing skateboards. When the player steps down on the front pedal 1, the rear pedal 2 moves upward. The cable 15 fixed to the bottom of the rear pedal 2 is pulled upward, causing the first winding wheel 20 on the rear wheel axle 14 to rotate. The first winding wheel 20 drives the first one-way bearing 18 to rotate, which in turn drives the rear wheel axle 14 to rotate. The rear wheel axle 14 then drives the two rear wheels 13 to rotate, propelling the new skateboard 100 forward. It should be noted that when the cable 15 fixed to the bottom of the rear pedal 2 drives the first winding wheel 20 on the rear wheel axle 14 to rotate, the second winding wheel 21 on the rear wheel axle 14 rotates in the opposite direction to the first winding wheel 20. Since the first one-way bearing 18 and the second one-way bearing 19 rotate in the same direction, the second one-way bearing 19 spins freely and does not cause the rear wheel axle 14 and the rear wheels 13 to rotate in the opposite direction.

[0020] Conversely, when the rear pedal 2 moves downward, the front pedal 1 moves upward. The pull cable 15 fixed to the bottom of the front pedal 1 is pulled upward, causing the second winding wheel 21 on the rear wheel axle 14 to rotate. The second winding wheel 21 drives the second one-way bearing 19 to rotate, which in turn drives the rear wheel axle 14 to rotate. The rear wheel axle 14 then drives the two rear wheels 13 to rotate, causing the new skateboard 100 to glide forward. It should be noted that when the pull cable 15 fixed to the bottom of the front pedal 1 drives the second winding wheel 21 on the rear wheel axle 14 to rotate, the rotation direction of the first winding wheel 20 on the rear wheel axle 14 is opposite to that of the second winding wheel 21. Since the one-way bearings 18 and 19 rotate in the same direction, the first one-way bearing 18 spins freely and does not cause the rear wheel axle 14 and the rear wheels 13 to rotate in the opposite direction.

[0021] In other words, whether the front pedal 1 or the rear pedal 2 is pressed down, the rear wheel 13 will rotate, propelling the new skateboard 100 forward. Repeatedly pressing down the front pedal 1 or the rear pedal 2 will propel the new skateboard 100 forward continuously. Example 2

[0022] like Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown. The new skateboard 100 includes a front pedal 1 and a rear pedal 2. The new skateboard 100 includes a front support arm 3 and a rear support arm 4. The new skateboard 100 includes a base 5.

[0023] The new skateboard 100 includes a front wheel assembly. The front wheel assembly is located at the front end of the base 5. The front wheel assembly includes a front wheel 8 and a front wheel axle 9. In this embodiment, there are two front wheels 8.

[0024] The novel skateboard 100 includes a rear wheel assembly. The rear wheel assembly, located at the rear end of the base 5, includes a rear wheel 13 and a rear wheel axle 14. In this embodiment, there are two rear wheels 13. The novel skateboard 100 includes a steering mechanism, which comprises a horizontal rotating bracket 10, a base plate 11, and a ball bearing (not shown). The rear wheel 13, rear wheel axle 14, horizontal rotating bracket 10, base plate 11, and ball bearing (not shown) together constitute a swivel wheel. In this embodiment, each rear wheel 13 is equipped with its own steering mechanism, meaning the rear end of the base 5 has two swivel wheels. When the novel skateboard 100 needs to turn while gliding forward, the foot on the rear pedal 2 and the body slightly swing left or right, causing the two horizontal rotating brackets 10 to rotate, the two rear wheels 13 to turn and slide left or right, and the two front wheels 8 to turn synchronously.

[0025] The new skateboard 100 includes a transmission mechanism, which comprises a chain drive mechanism. The chain drive mechanism includes a chain 25, a first guide pulley 16, a guide sprocket 26, and a one-way clutch. Both ends of the chain 25 are connected to the front pedal 1 and the rear pedal 2, respectively. The base 5 has the first guide pulley 16 at its bottom and the guide sprocket 26 at its rear end. The one-way clutch uses a one-way flywheel, similar to those used in existing bicycles. Two one-way flywheels are fixed on the front axle 9: a first one-way flywheel 27 and a second one-way flywheel 28, with the first and second flywheels rotating in the same direction. One end of the chain 25 is fixed to the bottom of the front pedal 1, then hooked onto the first one-way flywheel 27 and leads out to connect to the first guide pulley 16. After being guided by the first guide pulley 16, it returns to be hooked onto the second one-way flywheel 28 and leads out to connect to the guide sprocket 26. After being guided by the guide sprocket 26, the other end of the chain 25 is fixed to the bottom of the rear pedal 2. It should be noted that one section of the chain 25 connecting the first guide pulley 16 is replaced by a steel wire rope 29, and the two ends of the steel wire rope 29 are reconnected to the chain 25. The novel skateboard 100 of this embodiment adopts a front wheel 8 drive mode.

[0026] It should be understood that, in some embodiments, the transmission mechanism includes, but is not limited to, wire drive mechanism and chain drive mechanism.

[0027] The novel skateboard 100 includes an anti-slip mechanism, with the front pedal 1 and rear pedal 2 equipped with the anti-slip mechanism. In this embodiment, the anti-slip mechanism is a raised dot 30. It should be understood that in some embodiments, the anti-slip mechanism includes, but is not limited to, an anti-slip layer, an anti-slip coating, an anti-slip mat, a guard, sandpaper, raised dots, raised strips, recesses, footwells, and textures.

[0028] The base 5 is equipped with a handrail 31. In this embodiment, the handrail 31 is located on the right side of the base 5. The handrail 31 consists of a handle 32 and a vertical tube 33. The vertical tube 33 is a telescopic structure, consisting of two telescopic tubes 34, and its height can be adjusted. The lower end of the vertical tube 33 can also be folded and stored. When the new skateboard 100 slides forward, holding the handrail 31 with both hands provides greater stability and safety, making it especially suitable for children.

[0029] The operating principle of the new skateboard 100: The player stands sideways with both feet on the front pedal 1 and the rear pedal 2, the same stance as existing skateboards. When the player steps down on the front pedal 1, the rear pedal 2 moves upward. The chain 25 fixed to the bottom of the front pedal 1 is pulled downward, causing the first one-way flywheel 27 on the front axle 9 to rotate. The first one-way flywheel 27 drives the front axle 9 to rotate, which in turn drives the two front wheels 8, propelling the new skateboard 100 forward. It should be noted that when the chain 25 fixed to the bottom of the front pedal 1 drives the first one-way flywheel 27 on the front axle 9 to rotate, the second one-way flywheel 28 on the front axle 9 rotates in the opposite direction. Since the first and second one-way flywheels rotate in the same direction, the second one-way flywheel 28 spins freely and does not cause the front axle 9 or the front wheels 8 to rotate in the opposite direction.

[0030] Conversely, when the rear pedal 2 is pressed downwards, the front pedal 1 moves upwards. The chain 25 fixed to the bottom of the rear pedal 1 is pulled downwards, causing the second one-way flywheel 28 on the front axle 9 to rotate. The second one-way flywheel 28 then drives the front axle 9 to rotate, which in turn drives the two front wheels 8 to rotate, propelling the new skateboard 100 forward. It should be noted that when the chain 25 fixed to the bottom of the rear pedal 2 drives the second one-way flywheel 28 on the front axle 9 to rotate, the rotation direction of the first one-way flywheel 27 on the front axle 9 is opposite to that of the second one-way flywheel 28. Since the one-way rotation directions of the first and second one-way flywheels 27 and 28 are the same, the first one-way flywheel 27 spins freely and does not cause the front axle 9 and the front wheels 8 to rotate in the opposite direction.
