Light-duty saddle handle-type rapid folding portable electric bicycle

Abstract

The invention relates to a light-duty saddle handle-type rapid folding portable electric bicycle. A bicycle body is arranged left and right in parallel by virtue of two flat aluminium tubes; a front punching piece, a five-way front stay tube, a five-way rear stay tube, a linkage connection piece, a countershaft front stay tube, a countershaft rear stay tube and an L-shaped rear fork pipe are respectively welded with the two flat aluminium tubes, a front frame is formed by connecting a front pipe piece, a front beam tube and a front piece folding blade; the lower part of a seat tube is welded with a seat tube folding blade; the seat tube folding blade is connected with the linkage connection piece; the two ends of a connecting rod are connected with the seat tube folding blade and the front piece folding blade; the front piece folding blade is connected with a front punching piece of the vehicle body; the seat tube folding blade is also connected with a latch hook; the latch hook is matched with a semi-circle lock shaft; a V-shaped folding handle is fixedly connected with a front fork, the front fork is provided with a front wheel, a rear fork piece is connected with a rear wheel, a manpower driving mechanism is arranged among a five-way tube, a countershaft tube and the rear wheel, a motor is arranged at the rear wheel; and a vehicle battery and a controller are respectively placed into a battery box.

Description

Technical field [0001] The invention relates to a folding electric bicycle, in particular to a light saddle handle type quick folding portable electric bicycle which is quick and convenient to open or fold, and can drag the bicycle by grasping the saddle by hand after folding. technical background [0002] At present, there are many styles of folding electric bicycles on the market, but folding electric bicycles that can be folded very small, fold quickly, and can be dragged after folding are relatively rare. The designer designed the quick folding first Although the saddle handle portable electric bicycle solves the problem of being able to fold very small, quickly fold and can be towed after folding, the main beam of the car body is made of aluminum extruded profiles with overlapping two groove bottoms. Due to structural reasons, the profile cannot be made into a closed tube shape, so it must be designed to be thicker, which makes the weight of the car relatively heavy. Summar...

Problems solved by technology

[0002] At present, there are many styles of folding electric bicycles on the market, but folding electric bicycles that can be folded very small and quickly, and can be dragged after folding are relatively rare. The fast folding electric bicycle designed by the designer first Saddle-handled portable electric bicycle, although it solves the problem that it can be folded very small, folded quickly and can be dragged after folding, the main beam of the vehicle body is made of aluminum extruded profiles stacked on the bottom of two grooves. Due to structural reasons, the profile cannot be made into a closed tube shape, so it must be designed thicker, which makes the weight of the car relatively heavy
