The foldable portable bicycle comprises a bicycle beam, a front head tube, a front fork, a V-shaped foldable handlebar, a front wheel, a rear wheel, a bicycle saddle and a driving mechanism, wherein the bicycle beam is combined into a four-connecting-rod mechanism through a front beam tube, a rear beam tube, a front rotating vane, a first grooved piece, a second grooved piece, an L-shaped piece, a lower connecting rod and a first latch hook; the front fork is rotationally connected with the front head tube; the front wheel is arranged on the front fork; the V-shaped foldable handlebar connected with the front fork is a clamping type locking piece V-shaped foldable handlebar; the bicycle saddle comprises a seat tube and a saddle; the seat tube is combined into a four-connecting-rod mechanism through a lower seat tube, an upper seat tube, a base, a lower rotating piece, a foldable vane, a dual-groove piece, a front connecting rod and a second latch hook; the saddle is connected to the upper seat tube; the driving mechanism comprises a middle axle, a crankshaft, a crankset, pedals, an auxiliary axle, a front-stage small chain wheel, a rear-stage chain wheel, a flywheel, a front-stage chain and a rear-stage chain, and is connected to a five-way tube, the back portion of the rear beam tube and the right side of the rear wheel.
Description
technical field [0001] The invention relates to a foldable portable bicycle, in particular to a four-link foldable portable bicycle with a beam seat tube. technical background [0002] The several foldable bicycles designed by the designer earlier, though fast in folding speed and relatively small in size, failed to achieve the satisfactory effect of complete folding and more portable effect after folding due to reasons such as structure. Contents of the invention [0003] The purpose of the present invention is to provide a four-bar linkage mechanism on the beam and seat tube of a folding bicycle, and a V-shaped folding handle on the handlebar. Utilize the most effective folding of these three items to realize a perfectly folded bicycle. The utility model relates to a four-link folding portable bicycle with a beam and a seat tube. The object of the present invention is achieved like this; Car beam seat pipe four-link folding portable bicycle, comprises car beam, front he...
