[0056] Reference is made to Figures 1 to 8A preferred embodiment of the pedal transmission structure 1 of the scooter of this utility model mainly includes a vehicle body 10, a pedal 20, a return component 30, a transmission rod 40, a crankshaft 50, a wheel axle 60, a drive gear 70, two wheels 80, and a protective cover 90.

[0057] The vehicle body 10 has a main frame 11 and an upper seat 15, which are combined. The main frame 11 has two pivot plates 12, which are connected to the rear ends of the main frame 11 on both sides. The upper seat 15 has a first stop 16.

[0058] The pedal 20 is pivotally connected to the vehicle body 10 and can pivot between an initial angle and an end angle. The pedal 20 has a bracket 21, a footrest 22, and a second stop 23. The bracket 21 is pivotally connected to the vehicle body 10 by a bolt, the footrest 22 is fixed to the bracket 21, and the second stop 23 stops against the first stop 16 of the vehicle body 10 to prevent stepping beyond a preset range.

[0059] The return element 30 drives the pedal 20 to return to its initial angle. In this embodiment, the return element 30 is a torsion spring, which is sleeved on the bolt that pivotally connects the vehicle body 10 and the pedal 20. One end of the return element 30 abuts against the vehicle body 10, and the other end of the return element 30 abuts against the bracket 21 of the pedal 20.

[0060] One end of the transmission rod 40 is pivotally connected to the pedal 20, and the other end of the transmission rod 40 is pivotally connected to the crankshaft 50.

[0061] like Figure 8 As shown, the crankshaft 50 is actuated by the transmission rod 40. The crankshaft 50 has a first shaft portion 51, two connecting shaft portions 52, a second shaft portion 53, two counterweight portions 54, and a connecting portion 55. The first shaft portion 51 is pivotally connected to the transmission rod 40. Each connecting shaft portion 52 is connected to the first shaft portion 51. The second shaft portion 53 is connected to each connecting shaft portion 52. The second shaft portion 53 is pivotally connected to the pivot plate 12 of the vehicle body 10 by two bearings. Each counterweight portion 54 is connected to each connecting shaft portion 52. The connecting portion 55 connects two counterweight portions 54. However, in this invention, there may be only one connecting shaft portion 52 and only one counterweight portion 54.

[0062] The axle 60 has a wheel shaft 61 and a driven gear 62. The wheel shaft 61 is pivotally connected to the pivot plate 12 of the vehicle body 10 by two bearings. The driven gear 62 is connected to the wheel shaft 61 and meshes with the driving gear 70. In this embodiment, the number of teeth of the driven gear 62 is less than the number of teeth of the driving gear 70, but this utility model is not limited thereto.

[0063] The drive gear 70 is connected to the second shaft portion 53 of the crankshaft 50 and rotates together with it.

[0064] Each wheel 80 is equipped with two one-way bearings B1 at both ends of the axle shaft 61 of the axle 60. However, the utility model is not limited to this, and only one one-way bearing B1 can be arranged on each of the left and right wheels 80.

[0065] The sleeve 85 is sleeved on the axle shaft 61 of the axle 60 and located between the bearing and the one-way bearing B1, so that the vehicle body 10, the axle 60 and the wheel 80 are kept in a relative position.

[0066] The shroud 90 is connected to the pedal 20 at the top and connected to the vehicle body 10 at the bottom, and the shroud 90 can be elastically deformed to cooperate with the movement.

[0067] In use, the pedal 20 is at the initial angle, the pedal 20 is stepped on, the elastic force of the restoring member 30 is overcome, the pedal 20 is actuated downward to swing to the terminal angle, the pedal 20 is actuated downward to drive the transmission rod 40, the transmission rod 40 drives the crankshaft 50 to rotate by a relative angle, the crankshaft 50 drives the driving gear 70 to rotate, the driving gear 70 drives the driven gear 62 to rotate, the driven gear 62 drives the axle shaft 61 to rotate, the axle shaft 61 drives the one-way bearing B1 to rotate, the one-way bearing B1 drives the wheel 80 to rotate, and the pedal 20 reaches the terminal angle.

[0068] When the pedal 20 is released, the elastic force of the restoring member 30 pushes the pedal 20 to swing to the initial angle, the transmission rod 40 drives the crankshaft 50 to return, the crankshaft 50 drives the driving gear 70 to return, the driving gear 70 and the driven gear 62 rotate reversely to return, the axle 60 returns relative to the one-way bearing B1, and the pedal 20 returns to the initial angle, during which the pedal 20 can be stepped on again.

[0069] Through the one-way bearing B1 arranged between the axle shaft 61 of the axle 60 and the wheel 80, when the axle shaft 61 rotates forward, the wheel 80 can be driven to rotate, and when the axle shaft 61 does not rotate or rotates backward, the one-way bearing B1 does not jam or reverse the wheel 80, but allows the wheel 80 to continue to rotate, so that the effect of smooth movement is achieved, thereby achieving the purpose of the utility model.

[0070] The second stop portion 23 is stopped by the first stop portion 16 of the vehicle body 10 to prevent stepping beyond the preset range, thereby achieving the purpose of rapid return.

[0071] The counterweight portion 54 is subjected to the action of gravity, so that the crankshaft 50 can assist the pedal 20 to return to the initial angle, the pedal 20 can be quickly returned to the initial angle, and the same purpose of the utility model is achieved.

[0072] Another preferred embodiment of the pedal driving structure 1 of the utility model scooter is shown in Figure 9 The difference between the embodiment and the previous embodiment is that:

[0073] In addition to the single direction bearing B1 installed in the wheel 80, a single direction bearing B1 is also installed in the driving gear 70 which is installed on the second shaft part 53 of the crankshaft 50, and the driving gear 70 is connected to the single direction bearing B1 and can only rotate in one direction; when the pedal 20 is actuated to the terminal angle, the single direction bearing B1 can still rotate the driven gear 62 through the single direction action; however, when the pedal 20 is returned to the initial angle, the single direction action of the single direction bearing B1 can prevent the driving gear 70 and the wheel shaft 60 from returning to rotate, reduce unnecessary actuation and wear, reduce some returning resistance, and make the pedal 20 quickly return to the initial angle. Thus, the same invention purpose of the utility model is achieved.

[0074] In other words, the single direction bearing B1 is connected to the second shaft part 53 of the crankshaft 50 and the wheel shaft rod 61 of the wheel shaft 60 respectively; the driving gear 70 is connected to the single direction bearing B1 installed on the crankshaft 50 and engages the driven gear 62; and the wheel 80 is connected to the single direction bearing B1 installed on the wheel shaft 60.

[0075] Another preferred embodiment (not shown in the figure) of the pedal driving structure 1 of the utility model scooter is similar to the above-mentioned embodiments, and the difference is that only the driving gear 70 has the single direction bearing B1 installed on the second shaft part 53 of the crankshaft 50, the driving gear 70 is connected to the single direction bearing B1 installed on the crankshaft 50 and engages the driven gear 62; and the wheel 80 is connected to the wheel shaft rod 61 of the wheel shaft 60 without the single direction bearing. Thus, the single direction driving and returning actuation can still be achieved, and the same invention purpose of the utility model is achieved.

[0076] In addition to the above embodiments, the utility model can also be changed in some other ways. For example, the driving gear 70 and the driven gear 62 can be directly driven, or indirectly driven through an intermediate gear or a gear belt.

[0077] Finally, it must be stated again that the components disclosed in the above-mentioned embodiments of the utility model are only for example and are not used to limit the scope of the application, and other equivalent components or changes should also be covered by the patent application range of the application.
