Description

Technical Field

[0001] The present invention relates to the technical field of scooters, and particularly to a new type of scooter. Background Art

[0002] Existing scooters driven by human power are a common children's entertainment product. One foot needs to be used to pedal the ground to drive the scooter to slide. This driving method is not only troublesome, slow, lacking in fun, but also has a relatively single function. Thus, there have emerged some scooter patents that can drive the scooter to slide without relying on pedaling the ground.

[0003] For example, Chinese Patent CN202987447U (authorization announcement date: June 12, 2013) discloses a scooter. Left and right pedals are provided on both sides of the frame. By stepping on the left and right pedals to move up and down reciprocally, the scooter can be driven to slide. This scooter does not need to pedal the ground to drive the scooter to slide. However, the transmission mechanism of this scooter adopts a gear transmission mechanism, and the transmission ratio is not high, so the sliding speed of the scooter is limited. Therefore, the function is still relatively single.

[0004] Another example is Chinese Patent CN207089571U (authorization announcement date: March 13, 2018) which discloses a scooter. Left and right pedals are provided on both sides of the frame. The transmission mechanism adopts a drive rope or chain transmission mechanism, and the transmission ratio is relatively high, so the scooter can obtain a relatively high sliding speed. However, the left and right pedals of this scooter are pivotally connected to the part near the front end of the frame, that is, the left and right pedals can rotate back and forth. The drive mechanism (i.e., the transmission mechanism) includes a drive rope arranged at the rear end of the frame and located between the left and right pedals, and the drive rope is in a vertical or approximately vertical state. When the rear end of the left or right pedal is lifted upward, the left or right pedal rotates forward. At this time, the upper end surface of the left or right pedal is an inclined surface. As the rear end of the left or right pedal is lifted higher and higher, the inclination of the upper end surface of the left or right pedal becomes larger and larger, and the stability and safety of a person standing on the left and right pedals and during movement become worse, especially for children. Moreover, as the rear end of the left or right pedal is lifted higher and higher, the inclination of the upper end surface of the left or right pedal becomes larger and larger, which is also not conducive to stable exertion when stepping down with both feet, especially continuous and stable exertion. The operational performance of the movement is not very ideal. These drawbacks are more obvious especially when the scooter needs to accelerate continuously. Summary of the Invention

[0005] To solve the technical problems existing in the existing human-powered scooters, the present invention provides a new type of scooter. Left and right support arms are provided on both sides of the frame. One end of the left support arm is connected to the left pedal, and one end of the right support arm is connected to the right pedal. The other ends of the left support arm and the right support arm are hinged to the frame, and the left support arm and the right support arm can rotate left and right. When the left pedal and the right pedal move up and down reciprocally, the upper surfaces of the left pedal and the right pedal can always remain horizontal. Moreover, the transmission mechanism of the new type of scooter adopts a cable transmission mechanism or a chain transmission mechanism, with a relatively high transmission ratio, and a relatively high sliding speed, even a high speed, can be obtained.

[0006] The technical solution adopted by the present invention: A new type of scooter, comprising: A head, the head includes a handle, a riser and a front wheel assembly, and the upper end of the riser is connected to the handle; A frame; A front wheel assembly, a front wheel assembly is provided at the front end of the frame, and the front wheel assembly includes a front wheel and a front wheel axle, with at least one front wheel; A rear wheel assembly, a rear wheel assembly is provided at the rear end of the frame, and the rear wheel assembly includes a rear wheel and a rear wheel axle, with at least one rear wheel; and A left pedal and a right pedal, a left pedal and a right pedal are provided on both sides of the frame; A cable transmission mechanism or a chain transmission mechanism; and Left and right support arms, left and right support arms are provided on both sides of the frame. One end of the left support arm is connected to the left pedal, and one end of the right support arm is connected to the right pedal. The other ends of the left support arm and the right support arm are hinged to the frame, and the left support arm and the right support arm can rotate left and right.

[0007] The beneficial effects of the present invention: 1. When the left pedal and the right pedal of the new type of scooter move up and down reciprocally, the upper surfaces of the left pedal and the right pedal can always remain horizontal. The stability and safety of a person standing on the left pedal and the right pedal and during movement are relatively high, especially for children. Moreover, the fact that the upper surfaces of the left pedal and the right pedal can always remain horizontal is also beneficial for stable exertion of force when stepping down with both feet, especially for continuous and stable exertion of force, and the movement operability is good. Especially when the new type of scooter needs to accelerate continuously, these beneficial effects are more obvious; 2. The transmission mechanism of the new type of scooter adopts a cable transmission mechanism or a chain transmission mechanism, and the new type of scooter can obtain a relatively high sliding speed, even a high speed. Therefore, the functions of the new type of scooter are relatively rich. It can be used as a children's entertainment item, a means of transportation like a bicycle, or a sports competition item; 3. The new type of scooter brings a brand-new experience and fun.

[0008] The beneficial effects of the present invention are better demonstrated in the following specific embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

The stability and safety of a person standing on the left pedal 16 and the right pedal 17 and during movement are relatively high, especially for children. Moreover, the fact that the upper end surfaces of the left pedal 16 and the right pedal 17 can always remain horizontal is also beneficial for stable force application when stepping down with both feet, especially for continuous and stable force application, and the movement operability is good. These beneficial effects are more obvious especially when the new type scooter 100 needs to accelerate continuously.

[0017] The new type scooter 100 further includes a cable drive mechanism. The cable drive mechanism includes a cable 21, a guide pulley, a wire winding wheel, and a one-way clutch. Both ends of the cable 21 are respectively connected to the left pedal 16 and the right pedal 17.

After guiding, the other end of the cable 21 is fixed upward to the bottom of the right pedal 17.

[0019] The new type scooter 100 includes an anti-slip mechanism. The left pedal and the right pedal are provided with anti-slip mechanisms. In this embodiment, the anti-slip mechanism is the edge 30.

[0020] The new type scooter 100 further includes a braking mechanism. In this embodiment, the braking mechanism is the handbrake 44. The handbrake 44 is arranged at the front of the vehicle head. The handbrake 44 is the prior art of the existing human-powered scooter and will not be elaborated here.

[0021] The main body of the new type scooter 100, including the vehicle frame 1, the vertical pipe 3, the front fork 6, the left pedal 16, the right pedal 17, the left support arm 18, the right support arm 19, etc., is processed and made of aluminum alloy material. The front wheel 4 and the rear wheels 12 are made of high-elastic PU (polyurethane) wheels.

[0022] The movement principle of the new type scooter 100: The player steps on the left pedal 16 and the right pedal 17 with both feet respectively, and the standing position is the same as that of the existing human-powered scooter. Both hands hold the left and right sides of the handle 2 respectively. When stepping on the left pedal 16 and moving downward, the right pedal 17 moves upward. The cable 21 fixed to the bottom of the right pedal 17 is pulled upward and drives the second winding wheel 29 on the right side of the rear wheel axle 13 to rotate. The second winding wheel 29 drives the second one-way bearing 27 to rotate. The second one-way bearing 27 drives the rear wheel axle 13 to rotate. The rear wheel axle 13 drives the two rear wheels 12 to rotate, and the new type scooter 100 slides forward. It should be noted that when the cable 21 fixed to the bottom of the right pedal 17 drives the second winding wheel 29 on the right side of the rear wheel axle 13 to rotate, at this time, the rotation direction of the first winding wheel 28 on the left side of the rear wheel axle 13 is opposite to that of the second winding wheel 29 on the right side of the rear wheel axle 13. Since the first one-way bearing 26 and the second one-way bearing 27 are arranged in the same direction on the rear wheel axle 13. At this time, the first one-way bearing 26 idles and will not drive the rear wheel axle 1 and the rear wheels 12 to reverse.

[0023] Conversely, when the right pedal 2 is stepped on and moves downward, the left pedal 1 moves upward. The wire 21 fixed to the bottom of the left pedal 1 is pulled upward and drives the first wire winding wheel 28 on the left side of the rear wheel shaft 13 to rotate. The first wire winding wheel 28 drives the first one-way bearing 26 to rotate. The first one-way bearing 26 drives the rear wheel shaft 13 to rotate. The rear wheel shaft 13 drives the two rear wheels 12 to rotate, and the new scooter 100 slides forward. It should be noted that when the wire 21 fixed to the bottom of the left pedal 1 drives the first wire winding wheel 28 on the left side of the rear wheel shaft 13 to rotate, at this time, the rotation direction of the second wire winding wheel 29 on the right side of the rear wheel shaft 13 is opposite to that of the first wire winding wheel 28 on the left side of the rear wheel shaft 13. Since the first one-way bearing 26 and the second one-way bearing 27 are arranged in the same direction on the rear wheel shaft 13. At this time, the second one-way bearing 27 idles and does not drive the rear wheel shaft 13 and the rear wheels 12 to reverse.

[0024] That is to say, whether the left pedal 16 or the right pedal 17 is stepped on downward, the rear wheel shaft 13 and the rear wheels 12 can be driven to rotate, and the new scooter 100 slides forward. Stepping on the left pedal 16 and the right pedal 17 downward repeatedly can drive the new scooter 100 to slide forward continuously. Embodiment 2

[0025] As Figure 5 、 Figure 6 and Figure 7 shown. The new scooter 100 adopts a chain drive mechanism. The chain drive mechanism includes a chain 32, a guide pulley, a guide sprocket 33 and a one-way clutch.

A second cross bar 34 is provided at the middle position between the front end and the rear end of the vehicle frame 1. A guide sprocket 33 is provided at each of the left and right ends of the second cross bar 34. A third cross bar 35 is provided on the vehicle frame 1 between the second cross bar 34 and the rear wheel shaft 13. A fourth guide pulley 36 is provided at each of the two ends of the third cross bar 35. In this embodiment, the one-way clutch adopts a one-way flywheel, which is similar to the one-way flywheel used in existing bicycles. Two one-way flywheels are fixed on the rear wheel shaft 13 on both sides of the fixed bracket 14. The left one is the first one-way flywheel 37, and the right one is the second one-way flywheel 38. And the first one-way flywheel 37 and the second one-way flywheel 38 are arranged in the same direction on the rear wheel shaft 13.

[0026] One end of the chain 32 is fixed to the bottom of the left pedal 16, hangs downward on the guide sprocket 33 at the left end of the second crossbar 34, is led out after guiding and hangs on the first one-way flywheel 37 of the rear wheel shaft 13, and is led out after guiding. At this time, the chain 32 is connected to a steel wire rope 39, the steel wire rope 39 is connected to the fourth guide pulley 36 at the left end of the third crossbar 35, and then connected to the fourth guide pulley 36 at the right end of the third crossbar 35. After guiding, it is led out. At this time, the steel wire rope 39 is reconnected to the chain 32, the chain 32 hangs on the second one-way flywheel 38 of the rear wheel shaft 13, is led out after guiding, hangs on the guide sprocket 33 at the right end of the second crossbar 34, and the other end of the chain 32 is fixed upward to the bottom of the right pedal 17 after guiding.

[0027] The new type scooter 100 includes a left support arm 18 and a right support arm 19. In this embodiment, there are three left support arms 18 and three right support arms 19 respectively. A first hinge bracket 41 is provided at the middle position between the front end and the rear end of the vehicle frame 1, and a second hinge bracket 42 is provided at the bottoms of the left pedal 16 and the right pedal 17. One end of the three left support arms 18 is hinged to the second hinge bracket 42 of the left pedal 16, that is, one end of the left support arm 18 is connected to the left pedal 16. One end of the three right support arms 19 is hinged to the second hinge bracket 42 of the right pedal 17, that is, one end of the right support arm 19 is connected to the right pedal 17. The other ends of the three left support arms 18 and the other ends of the three right support arms 19 are hinged to the first hinge bracket 41 of the vehicle frame 1, that is, the other ends of the left support arm 18 and the right support arm are hinged to the vehicle frame 1, and the left support arm 18 and the right support arm 19 can rotate left and right. As Figure 8 shown, when the left pedal 16 and the right pedal 17 move up and down reciprocally, the upper end surfaces of the left pedal 16 and the right pedal 17 can always remain horizontal.

[0028] The new type scooter 100 includes an anti-slip mechanism. The left pedal 16 and the right pedal 17 are provided with an anti-slip mechanism. In this embodiment, the anti-slip mechanism is sandpaper 43, and the sandpaper 43 is pasted on the upper end surfaces of the left pedal 16 and the right pedal 17. It should be understood that in some embodiments, the anti-slip mechanism includes but is not limited to anti-slip layers, anti-slip coatings, anti-slip pads, edges, sandpaper, bumps, ridges, depressions, footwells, and textures.

[0029] Principle of movement of the new scooter 100: The player steps on the left pedal 16 and the right pedal 17 with both feet respectively, standing in the same position as that of the existing human-powered scooter, and holds the left and right sides of the handle 2 with both hands. When stepping on the left pedal 16 and moving downward, the right pedal 17 moves upward. The chain 32 fixed to the bottom of the right pedal 17 is pulled upward and drives the second one-way flywheel 38 on the right side of the rear wheel shaft 13 to rotate. The second one-way flywheel 38 drives the rear wheel shaft 13 to rotate, and the rear wheel shaft 13 drives the two rear wheels 12 to rotate, and the new scooter 100 slides forward. It should be noted that when the chain 32 fixed to the bottom of the right pedal 17 drives the second one-way flywheel 38 on the right side of the rear wheel shaft 13 to rotate, at this time, the rotation direction of the first one-way flywheel 37 on the left side of the rear wheel shaft 13 is opposite to the rotation direction of the second one-way flywheel 38 on the right side of the rear wheel shaft 13. Since the first one-way flywheel 37 and the second one-way flywheel 38 are arranged in the same direction on the rear wheel shaft 13, at this time, the first one-way flywheel 37 idles and does not drive the rear wheel shaft 13 and the rear wheels 12 to reverse.

[0030] Conversely, when stepping on the right pedal 17 and moving downward, the left pedal 16 moves upward. The chain 32 fixed to the bottom of the left pedal 1 is pulled upward and drives the first one-way flywheel 37 on the left side of the rear wheel shaft 13 to rotate. The first one-way flywheel 37 drives the rear wheel shaft 13 to rotate, and the rear wheel shaft 13 drives the two rear wheels 12 to rotate, and the new scooter 100 slides forward. It should be noted that when the chain 32 fixed to the bottom of the left pedal 16 drives the first one-way flywheel 37 on the left side of the rear wheel shaft 13 to rotate, at this time, the rotation direction of the second one-way flywheel 38 on the right side of the rear wheel shaft 13 is opposite to the rotation direction of the first one-way flywheel 37 on the left side of the rear wheel shaft 13. Since the first one-way flywheel 37 and the second one-way flywheel 38 are arranged in the same direction on the rear wheel shaft 13, at this time, the second one-way flywheel 38 idles and does not drive the rear wheel shaft 13 and the rear wheels 12 to reverse.
