Problems solved by technology

[0002] Existing electric bicycles have problems such as large volume, heavy weight, and inconvenient charging. Some of them have no moving wheels after folding, and they can only be carried by hand. The suitcase-type electric vehicle solves the problem of inconvenient movement after folding. While meeting the requirements of portability, it is difficult to meet the requirements of electric bicycles such as vertical obstacle clearance height, speed, wheelbase, load, and short braking distance. skills requirement

Embodiment 1

[0050] Such as Figure 4 As shown, the schematic diagram of the chain transmission structure of the suitcase type folding 2-wheel electric bicycle with variable wheelbase, the pedal central axis device 159 is installed on the pedal central axis seat device 160, the central axis driving gear device 161 is connected with the driven gear device 162, from The moving gear device 162 and the chain gear device 163 are fixed on the folding arm shaft device 142 to rotate coaxially and synchronously. The chain gear device 163 links the fly gear device 164, and the fly gear device 164 and the rear wheel device 147 are installed on the rear axle device 146 to realize foot movement. Cycling function.

[0051] Such as figure 2 As shown, the electric vehicle controller device 166 is installed under the longitudinal beam of the second side frame device 134 of the rear suitcase type chassis, and the storage battery device 167 is installed under the longitudinal beam of the first side frame d...

Embodiment 2

[0057] Such as Figure 5As shown, the frame structure suitcase type folding 2-wheel variable wheelbase bicycle simulated suitcase schematic diagram, embodiment 2 compared with embodiment 1 cancels the electric vehicle controller device 166, storage battery device 167, rear wheel hub of embodiment 1 Motor device 168, embodiment 2 needs to adopt backguy spring lock device 239 at the 1st end of folding arm guide groove 2nd end backguy spring lock device 240, with backguy spring lock switch device 241 because there is no battery, To control the opening and closing of the 4 spring locks, when the wheelbase is changed, use the pull wire spring lock switch device 241 to simultaneously open the first and second pull wire spring lock devices 239 at the first end of the folded arm guide groove and the first and the first 2 pull wire spring locking devices 240 at the second ends of the guide grooves of the folding arms, the folding arm device 245, the driven gear device 262 linking the f...

Embodiment 3

[0059] Such as Figure 9 As shown, the frame structure suitcase type folding 2-wheel variable wheelbase electric vehicle simulation suitcase device schematic diagram, embodiment 3 compared with embodiment 1 cancels the chain transmission device of embodiment 1, adopts rear wheel hub motor device 360 ​​to drive. The principles of other parts of Embodiment 3 are exactly the same as those of Embodiment 1, and will not be explained repeatedly.
