In other embodiments, spring pearl can be arranged at the upper inwall of mounting groove 4251 or lower inwall, raised line 54
Upper side or downside correspondingly offers backstop hole.
It is structural representation when foldable electric bicycle 100 of the present invention folds also referring to Fig. 8 and Fig. 9, Fig. 8,
Fig. 9 is the structural representation at Fig. 8 another visual angle.When without using the foldable electric bicycle 100, rotatable leg control operation
Bar 46 makes it be moved towards the shell 20, and stretches the leg control action bars 46, is fastened in the leg control action bars 46 described
On holding part 22.Each balance control pedal 60 is folded towards the shell 20, makes the upper table of the balance control pedal 60
The shell 20 is pressed close in face.The backstop that every positioning piece 427 departs from the raised line 54 to corresponding connecting shaft 52 is operated again, is inwardly turned
The connecting shaft 52 is moved, until trailing wheel 50 is folded to the bottom of the vehicle frame 10.Now, the leg control action bars 46, balance control
Pedal 60 and trailing wheel 50 processed are completed to fold, so as to be convenient for carrying the foldable electric bicycle 100.
During using the foldable electric bicycle 100, it is convex to the connecting shaft 52 that each connecting shaft 52 is rotated outwardly
Bar 54 is resisted against the rear wall of corresponding mounting groove 4251, operates the corresponding backstop of keeper 427 in the front side of the raised line 54
Wall, to prevent the connecting shaft 52 from rotating.Now, two trailing wheels 50 are located at the left and right sides of the vehicle frame 10 respectively.Court
It is outer to pull each balance control pedal 60, the balance control pedal 60 is turned to level along corresponding connecting rod 173
State.Pull up the leg control action bars 46 and disengage it from fixing with the holding part 22.Unlatching shift knob 25 makes described
Foldable electric bicycle 100 starts, and bicyclist is stood on two balance control pedals 60, the leg control action bars
46 lever 462 is held between the bipod of bicyclist, and the pressure inductor on balance control pedal 60 is sent a signal to
The control board 70.When station tilts in the body forward of the bicyclist of balance control pedal 60, pass through the gyro
Instrument sensor 72 and the controlled motor 302 of the control board 70 drive the front driving wheel 30 to rotate, and make the folding electric
Dynamic scooter 100 moves forward；When station tilts backwards in the body of the bicyclist of balance control pedal 60, pass through the top
Spiral shell instrument sensor 72 and the driving of the controlled motor of the control board 70 state front driving wheel 30 and reduce speed, stop the rotation or make
The foldable electric bicycle 100 retreats.When the foldable electric bicycle 100 needs to turn to the right, bicyclist's
Bipod promotes to the right the lever 462, drives the connecting rod 45 and drive gear 47 clockwise by leg control action bars 46
Rotate, the drive gear 47 drives the driven gear 48 and rotating bar 422 to rotate counterclockwise, and the driven gear 48 drives
Two connecting shafts 52 turn left centered on the axial line along the rotating bar 422.Because front driving wheel 30 is driving wheel, two
Trailing wheel 50 is deflecting roller, so when foldable electric bicycle 100 advances, what the foldable electric bicycle 100 travelled
Turn to just with the steering of trailing wheel 50 on the contrary, i.e. trailing wheel 50 turns left and foldable electric bicycle 100 bears right to this
When, the rotation direction of the lever 462 is consistent with the steering of foldable electric bicycle 100, to the right.When described collapsible
When electric bicycle 100 needs to turn to the left, the bipod of bicyclist promotes the lever 462 to the left, passes through leg control action bars
46 drive the connecting rod 45 and drive gear 47 to rotate counterclockwise, and the drive gear 47 drives the driven gear 48 and turned
Lever 422 is rotated clockwise, and the driven gear 48 is driven centered on axial line of two connecting shafts 52 along the rotating bar 422
Turn right, trailing wheel 50 turns right and foldable electric bicycle 100 is born left to now, the lever 462 turns
Dynamic direction is consistent with the steering of foldable electric bicycle 100, to the left.Steering and folding electric due to leg control action bars 46
The traveling of dynamic scooter 100 is turned to unanimously, accordingly, it is capable to facilitate bicyclist to operate.
Above is the embodiment of the embodiment of the present invention, it is noted that come for those skilled in the art
Say, on the premise of principle of the embodiment of the present invention is not departed from, several improvements and modifications can also be made, these improvements and modifications
It is also considered as protection scope of the present invention.
