Product.Wherein, since the shaft of two handles 15 is overlapped, folding electric bassinet structure can be made more compact, improve electric motor bicycle with folding
Reliability, while being designed and manufactured convenient for electric motor bicycle with folding.It is opposite in head tube 11 when needing for electric motor bicycle with folding to be unfolded
While vehicle frame 10 rotates, the handlebar body of rod 14 is rotated relative to head tube 11, so that the handlebar body of rod 14 and head tube 11 are conllinear, and this
When the handlebar body of rod 14 and front fork 12 it is fixed, with when the handlebar body of rod 14 rotates, front fork 12 can be rotated synchronously with the handlebar body of rod 14.
Two handles 15 rotate the position vertical as vertical handgrip body 14, then by locker 16 that two handles 15 are fixed, this
When user the steering of the handlebar body of rod 14 can be manipulated by handle 15, and then the steering of front fork 12 and front-wheel 31 can be manipulated.
Wherein, as shown in Fig. 7, Figure 18 to Figure 20, locker 16 include hook 33 in a handle 15 and
Handle 35 and hitch 34 on another handle 15, handle 15 and handle 35 are rotatablely connected by shaft, hitch 34 and turn
It is rotatablely connected 35 by shaft.When state is rotated to state shown in Figure 19 two handles 15 as shown in Figure 18, handle 35 to
Upper rotation, hitch 34 are socketed in outside hook 33, and subsequent handle 15 rotates down, two rotations of handle 15 to extreme position (such as
For the conllinear position of two handles 15) while, hitch 34 is stuck on hook 33, realizes the relatively fixed of handle 15.
Wherein, as shown in Figure 3 and Figure 4, the lower end of the handlebar body of rod 14 is provided with body of rod hinge 141, and the top of front fork 12 is set
It is equipped with front fork hinge 124, body of rod hinge 141 is connected with front fork hinge 124 by shaft.When electric motor bicycle with folding is in unfolded state
When, body of rod hinge 141 and front fork hinge 124 are bonded, and head tube 11 is equipped with protrusion 17, and the body of rod is equipped with to be adapted to protrusion 17
Blind hole, so that head tube 11 can be rotated with the handlebar body of rod 14 when the handlebar body of rod 14 rotates.
The section of further preferably design protrusion 17 is polygon, in order to torque between the handlebar body of rod 14 and head tube 11
Transmitting.
Wherein, as shown in figs. 2 and 10, handle 15 includes interconnecting piece 151 and grip part 152, the connection of two handles 15
Portion 151 is connect by the same shaft with the handlebar body of rod 14, and grip part 152 is fixedly connected with (such as passing through welded connecting) and is connecting
The one end of portion 151 far from shaft.When two handles 15 turn to conllinear position, the grip part 152 of two handles 15 is conllinear
And grip part 152 and the handlebar body of rod 14 are against convenient for improving the fixed reliability of two handles 15.
As shown in Fig. 7, Figure 18 to Figure 20, in any of the above-described embodiment, further, the upper end of the handlebar body of rod 14 be equipped with
Handle 15 corresponding raised 17, handle 15 are equipped with and raised 17 corresponding stuck points 18, when handle 15 is rotated up, 18 energy of stuck point
Enough cross protrusion 17 and with protrusion 17 against so that handle 15 is maintained at the position after rotation, wherein protrusion 17 is elastic bumps
17 (such as protrusion 17 is the reed being fixed on the handlebar body of rod 14).
In the present solution, stuck point 18 rotates together with handle 15 when handle 15 is rotated up, stuck point 18 is crossed in rotation
Protrusion 17 and with protrusion 17 against (cross raised 17 procedure protrusions 17 first move down move up afterwards), handle at this time
15 can be maintained at the position after rotation.By setting stuck point 18 and protrusion 17, user's one-handed performance can make 15 phase of handle
The handlebar body of rod 14 is rotated as the approximately perpendicular position of vertical handgrip body 14, subsequent user's one hand can pass through locker 16

Motor-car raises the car body of electric motor bicycle with folding when being unfolded.Meanwhile when electric motor bicycle with folding folds, first the rotation of head tube 11 and with it is fixed
Position crossbeam 1011 against.Subsequent rear wheel frame 19 is rotated into folding space, and rear wheel frame 19 can only rotate under the limitation of front-wheel 31
Limited angle, and rear wheel frame 19 tilts upwards, can make full use of the space of 11 lower section of head tube, ties after folding electric motor bicycle with folding
Structure is more compact, and the volume of occupancy is smaller, is convenient for the folded carrying of electric motor bicycle with folding.
As shown in Fig. 8, Fig. 9, Figure 14 to Figure 17, in any of the above-described embodiment, further, further includes: saddle pillar 20,
(such as connecting by shaft) is rotatably coupled with vehicle frame 10；Support plate 21, the upside for being fixedly arranged on saddle pillar 20 are (such as logical
It crosses and is bolted)；Saddle 22 is rotatably arranged on support plate 21 (such as connecting by shaft), wherein at electric motor bicycle with folding
When unfolded state, from rear-wheel 32 to 31 direction of front-wheel, support plate 21 is tilted down and saddle 22 is bonded with support plate 21；Work as folding
Folded electric vehicle becomes folded state from unfolded state, saddle pillar 20 rotate forward and with position crossbeam 1011 against while saddle
Seat 22 rotation separated with support plate 21 and with position crossbeam 1011 against.
In the present solution, when electric motor bicycle with folding is in unfolded state, support plate 21 supports as shown in Fig. 8, Fig. 9 and Figure 14
Saddle 22, user are sitting on saddle 22 and drive electric motor bicycle with folding；When electric motor bicycle with folding becomes folded state from unfolded state,
As shown in figure 16, saddle 22 rotates backward, subsequent saddle pillar 20 to 31 direction of front-wheel rotate, and with positioning crossbeam 1011 against
Saddle 22 is during rotation with vertical beam 102 against (as shown in figure 15).In the present solution, when electric motor bicycle with folding folds, saddle
Bracket 20 and positioning crossbeam 1011 against, saddle 22 and vertical beam 102 against, with can reduce saddle pillar 20, support plate 21 with
And the volume that saddle 22 is occupied when electric motor bicycle with folding folds.
Wherein, further, from the front to the back, support plate 21 tilts gradually downward, in order to provide better branch for user
Support.
As shown in Fig. 8, Fig. 9, Figure 12 and Figure 13, in any of the above-described embodiment, further, further includes: pedal shaft 23,
Pedal shaft 23 be vertically arranged and with vehicle frame 10 be rotatably coupled (vehicle frame 10 be equipped with axis hole, pedal 24 rotation insertion axis hole
And can be rotated in axis hole)；Pedal 24 is set in pedal shaft 23 and vertical with pedal shaft 23；Prominent bamboo shoot 25, turn set on pedal
It is on axis 23 and vertical with pedal shaft 23, wherein when electric motor bicycle with folding is in unfolded state, pedal 24 is prominent to outside vehicle frame 10；
When electric motor bicycle with folding becomes folded state from unfolded state, pedal shaft 23 is rotated, and pedal 24 is bonded with vehicle frame 10 and prominent bamboo shoot
25 with rear wheel frame 19 and saddle pillar 20 against to limit the downward rotation of rear wheel frame 19 and saddle pillar 20 is upward turns
It is dynamic.
In the present solution, pedal 24 is fixed in pedal shaft 23, when electric motor bicycle with folding is in unfolded state, pedal 24 to
Outer protrusion allows the user to the foot when driving electric motor bicycle with folding and is placed on pedal 24；When electric motor bicycle with folding is become by unfolded state
When for folded state, pedal shaft 23 is rotated, and prominent bamboo shoot 25 rotate with pedal 24 with pedal shaft 23 together, up to pedal 24 and vehicle
Frame 10 is bonded, and prominent bamboo shoot 25 dash forward bamboo shoot 25 and rear wheel frame 19 and saddle pillar 20 against can limit rear-wheel by prominent bamboo shoot 25
The rotation of frame 19 and saddle pillar 20 locks rear wheel frame 19 and saddle pillar can be realized while pedal 24 is packed up
20.Pass through this programme, it is not necessary to which the fixation device of special setting rear wheel frame 19 and saddle pillar 20 makes folding electric bassinet structure more
It is compact.Meanwhile operating procedure when electric motor bicycle with folding folds is decreased, user's manipulation is more convenient.
