The rotating portion 42 is fixed on the mounting portion. The peripheral edge of the rotating ring 42 has a radially outward extending portion 421. The plate 43 is pivotally connected to the outer end of the extending portion 421, and the extending portion 421 can increase the moment at which the footrest 43 rotates the outer ring gear 41 when pressed; the mounting plate 12 is fixed on the inner side of the side plate 11 The drive chain 46, the drive sprocket 45, the driven gear 44 and the driven sprocket 47 are both placed between the mounting plate 12 and the side plate 11, so as to prevent the support beam 20 from being folded in the storage space, and the transmission The chain 46, the drive sprocket 45, the driven gear 44, and the driven sprocket 47 interfere.
本发明中， 上述的外齿圈 41与从动齿轮 44啮合， 同时， 从动齿 轮 44通过链条传动机构输出动力并传递给传动组件， 由传动组件带 动车轮 30转动， 如此， 可以在踩踏两脚踏板 43时， 使车轮 30转动。 然而， 只要能够将脚踏板 43的动力经由驱动组件传递给传动组件即 可， 因此， 本发明中可以釆用其他的枢接在侧板 11上的转动部件替 代上述的外齿圈 41 , 釆用其他的另一个枢接在枢轴 21上的转动部件 替代上述的从动链轮 47 , 该两个转动部件之间可以釆用齿轮组同步 联接， 也可以是釆用其他的同步联接结构进行配合。 In the present invention, the outer ring gear 41 meshes with the driven gear 44, and at the same time, the driven gear 44 outputs power through the chain transmission mechanism and transmits it to the transmission assembly, and the transmission assembly drives the wheel 30 to rotate, so that the two legs can be stepped on. At the time of the pedal 43, the wheel 30 is rotated. However, as long as the power of the footrest 43 can be transmitted to the transmission assembly via the drive assembly, other rotating members pivotally attached to the side plate 11 can be used in the present invention instead of the outer ring gear 41, 釆Rotating member pivotally attached to the pivot 21 Instead of the driven sprocket 47 described above, the two rotating members may be synchronously coupled by a gear set, or may be mated with other synchronous coupling structures.
上述的传动组件包括内置于支撑梁 20中且沿支撑梁 20的高度方 向延伸的传动杆 51、 枢接在枢轴 21上且与从动链轮 47同步联接的 传动轴 52、 同步联接在传动轴 52上的第一伞齿轮 53、 同步联接在传 动杆 51上端部且与第一伞齿轮 53啮合的第二伞齿轮 54、 同步联接 在传动杆 51下端部的第三伞齿轮 55、 以及同步联接在车轮 30的轮 轴 31上且与第三伞齿轮 55啮合的第四伞齿轮 56 , 传动轴 52穿接在 枢轴 21中， 其二者的中心轴线重合， 上述的两从动链轮 47分别键连 接于传动轴 52的两端部， 由于两从动链轮 47是同步转动的， 因此， 在两从动链轮 47转动的情况下， 其二者共同驱动传动轴 52转动，传 动轴 52的转动动力通过第一伞齿轮 53与第二伞齿轮 54的配合传递 给传动杆 51 , 传动杆 51的转动动力通过第三伞齿轮 55和第四伞齿 轮 56的配合传递给车轮 30的轮轴 31 , 最终使车轮 30转动。 The transmission assembly includes a transmission rod 51 built in the support beam 20 and extending along the height direction of the support beam 20, a transmission shaft 52 pivotally coupled to the pivot shaft 21 and synchronously coupled with the driven sprocket 47, and synchronously coupled to the transmission a first bevel gear 53 on the shaft 52, a second bevel gear 54 synchronously coupled to the upper end of the transmission rod 51 and meshing with the first bevel gear 53, a third bevel gear 55 synchronously coupled to the lower end of the transmission rod 51, and a synchronization A fourth bevel gear 56 coupled to the axle 31 of the wheel 30 and meshing with the third bevel gear 55, the transmission shaft 52 is threaded into the pivot 21, the central axes of which coincide, the two driven sprockets 47 described above. The keys are respectively connected to the two ends of the transmission shaft 52. Since the two driven sprockets 47 rotate synchronously, when the two driven sprockets 47 rotate, the two drive the drive shaft 52 to rotate together, and the drive shaft The rotational power of 52 is transmitted to the transmission rod 51 through the cooperation of the first bevel gear 53 and the second bevel gear 54, and the rotational power of the transmission rod 51 is transmitted to the axle of the wheel 30 through the cooperation of the third bevel gear 55 and the fourth bevel gear 56. 31 Finally, the wheel 30 is rotated.
本发明中， 由于在车架 10上釆用驱动组件， 在支撑梁 20内置安 装传动组件， 由于支撑梁 20是绕枢轴 21相对于车架 1 0转动， 且驱 动组件的动力输出末端 （即从动链轮 47 ) 与传动组件衔接位置恰好 是在枢轴 21上的传动轴 52上， 因此， 在收折折叠车的过程中， 支撑 梁 20不会与驱动组件和传动组件发生任何干涉， 折叠车的传动装置 不会受到影响， 此结合配合两驱动组件分别设置于两侧板 1 1上的巧 妙结构， 使支撑梁 20在收折状态时恰好能够被置于两侧板 11之间， 从而利用了车架 10的内部空间， 缩小了折叠车收折状态的体积， 同 时， 如上述所描述， 由于枢轴 21与传动轴 52的中心轴线重合， 在支 撑梁 20处于收折状态时， 车轮 30可以正常转动， 甚至于折叠车可以 正常骑行。 In the present invention, since the drive assembly is used on the frame 10, the drive assembly is built in the support beam 20, since the support beam 20 is rotated relative to the frame 10 about the pivot 21, and the power output end of the drive assembly (ie, The driven sprocket 47) is engaged with the transmission assembly just on the transmission shaft 52 on the pivot 21, so that the support beam 20 does not interfere with the drive assembly and the transmission assembly during folding of the folding vehicle. The transmission device of the folding car is not affected, and the intimate structure of the two driving components respectively disposed on the two side plates 1 1 is matched, so that the supporting beam 20 can be placed between the two side plates 11 in the folded state. Thereby utilizing the internal space of the frame 10, reducing the volume of the folded state of the folding vehicle, At the time, as described above, since the pivot shaft 21 coincides with the central axis of the propeller shaft 52, when the support beam 20 is in the folded state, the wheel 30 can be normally rotated, and even the folding cart can normally ride.
