Deformable rack is connected to, the pull rod 5 cooperatively forms linkage mechanism with the gag lever post 3, Rear frame 4 and Deformable rack.
Specifically, the pull rod 5 includes the intermediate projections section 53 with difference in height and the pivot connection section 54 at both ends, i.e., the
One, which is pivotally connected section 541 and second, is pivotally connected section 542, and the first end 51 of the pull rod 5 is pivotally connected the pivoting point
44, the second end 52 of the pull rod 5 connect described first with 631 common pivot of third end of the middle connecting rod 63 and is pivotally connected
Point 64；The position of the intermediate projections section 53 matches with the column 14, so as to enable the pull rod 5 and the column 14
Dislocation is opened, and avoids generating interference with the column 14.
Further, the middle bearing can be lifted up when folding for convenience, in the second side of the column 14
The lifting handle 17 positioned at 16 top of Deformable rack connecting portion is additionally provided with, the lifting handle 17 includes integrally formed company
Socket part and grip part, the connecting portion are fixed on the column 14, and the grip part can any meet ergonomic
Shape and structure, the hollow frame of preferably approximate chamfering parallelogram, and be at least coated with rubber on its top side rail
Pad.
Although the structure of above-mentioned folding stand is preferred in the present embodiment, in other embodiments, the folding
The structure of folded vehicle frame can also include the known various foldable structures of above-mentioned Rear frame.
As shown in attached drawing 1- attached drawings 5, the front-wheel 90 is arranged on the front fork 701, and the motor 50 is preferably integrated in
On the front-wheel 90, certainly in other embodiments, the motor 50 can also be integrated on the trailing wheel 30, carried out by trailing wheel
Driving.
The handrail both ends of the headstock 703 are respectively arranged with speed adjusting lever 60 and brake hand handle 80, and the headstock 703
It is connect with the front fork 701 and the front fork 701 is driven to rotate.
The electric drive system includes the battery 40 of electrical connection, and the battery 40 is installed in described by battery case 401
On battery tray 47, and it is used to power for entire electric drive system between the column 14 and trailing wheel；The battery
40 be accumulator, including but not limited to lead-acid accumulator, lithium iron phosphate storage battery.
Motor 50 is integrated on the front-wheel 90 or trailing wheel 30, for the front-wheel 90 or trailing wheel 30 to be driven to rotate；
Speed adjusting lever 60 is arranged in the front frame 6, for adjusting the rotating speed of the motor 50；
Controller is arranged in the front frame 6 or Rear frame 4, for entire electric drive system to be controlled to run.
The electric motor bicycle with folding of the present invention, when under unfolded state, the front end area of the pivot connection 42 is contained in
In the container of the Rear frame connecting portion 15, and the end of the gag lever post 3 is resisted against the bottom surface boss of the Rear frame 4
It, can not be along first pivoting point 153 so as to which the pivot connection 42 for making the Rear frame is fixed in the container on 46
Rotation, at this point, as shown in Figure 2, the central axes B near normal states of the central axes A of the Rear frame 4 and the column 14；
Meanwhile the gag lever post 3 is support with the bottom surface boss 46, so as to limit the seat cushion branch pipe 2 affixed with it along described
Through-hole moves down.
On the other hand, the second pivot connection section 542 of the pull rod 5 contacts and with the roof of the limiting slot 12 by card
Only；Meanwhile the upper connecting rod 61 of the Deformable rack is resisted against the change with the region of one end that second pivoting point 161 is connect
It is locked on the roof of shape frame connecting portion 16, so as to which the one end for making whole deformation frame is fixed, simultaneously because the support of front wheel carrier 6
Effect, so as to which the other end for making the Deformable rack is fixed, under end-state, as shown in Figure 2, the central axes C of the Deformable rack
With the central axes B near normal states of the column 14.
At this point, i.e. rideable, when user is sitting on seat cushion 100, the gravity of human body applies downward pressure to entire vehicle frame
Power, so as to make the front end for pushing down the pivot connection 42 of the gag lever post 3 tightly, meanwhile, what the middle bearing 1 was born
Pressure makes the upper connecting rod 61 being resisted against at the roof of the Deformable rack connecting portion 16 without loosening tightly.
Speed adjusting lever 60 described in user's turn, so as to which the motor 50 be controlled to rotate at different rates, the motor 50
Rotation drives the front-wheel 90 to rotate, and the rotation of front-wheel 90 drives electric vehicle integrally to advance.
When being folded, the lower part of the gag lever post 3 is stirred to D directions, removes the lower end of the gag lever post 3
The bottom surface boss 46, and the lower end of the gag lever post 3 is made to enter in second through-hole.
At this point, since there is no limit on the one hand the seat cushion branch pipe 2 can be under the effect of gravity along the column
Through-hole on 14 moves down, and the gag lever post 3 is driven to move；On the other hand, the pivot connection 42 of the Rear frame 4
Be released and can be with first pivoting point 153 for axis rotation.
Therefore, when user puies forward the lifting handle 17 upwards, the middle bearing 1 is whole to be moved upwards, but the rear car
The trailing wheel end of frame 4 remains stationary as under the gravity of itself, so as to make the pivot connection 42 of the Rear frame 4 with described
One pivoting point 153 is axis rotation, and is upturned and produces in the container, 42 side of pivot connection of the Rear frame 4
Wall is gone to be bonded with the rib on the bottom surface 151 after limited, under end-state, as shown in attached drawing 4- attached drawings 5, the rear car
The central axes A of frame 4 and the central axes B of the column 14 are in near-horizontal state.
Simultaneously as the Deformable rack can not be lifted with one end that front wheel carrier 70 is connect under the gravity of front wheel carrier 70
Rise, so, the Deformable rack with one end that middle bearing 1 is connect with the lifting of the middle bearing 1, with second pivoting point
161 rotate and are lifted, so as to deform upon the Deformable rack；Due to the movement of the Deformable rack and Rear frame 4, the pull rod
5 also move therewith, when the pull rod 5 and one end that the Rear frame 4 is connect as Rear frame 4 rotate in place and after fix, institute
It states pull rod 5 and is approximately rendered as horizontality, at this time since the length of the pull rod 5 is fixed and it connect with the upper connecting rod 61
And in the limit hole, therefore, when the upper connecting rod 61 turns to the maximum moving range and length of the pull rod 5
It is limited, at this point, as shown in attached drawing 4- attached drawings 5, the central axes B of the central axes C of the Deformable rack and the column 14 is near
Like horizontality.
After the completion of vehicle frame folding, the trailing wheel 30 is in front-wheel 90 in same level, and front-wheel exists with trailing wheel
It is disposed proximate in the plane.
Embodiment 2
The present embodiment is close with the electric motor bicycle with folding overall structure of embodiment 1, and distinctive points are：The electric motor bicycle with folding is also
It is described including the crank 9 that the driving wheel 8, the driving driving wheel 8 that are mounted in the central axis hole 162 in the middle bearing 1 rotate
Foot-operated 10 are equipped on crank 9.
The driving wheel 8 connects sprocket wheel 20 by chain, and the sprocket wheel 20 is rotatably coupled to first pivoting point
153 and third pivoting point 43 at, the sprocket wheel 20 passes through the chain connection installation trailing wheel 30 on chain stay 41 in the rear.
When user does not need to exhaust using battery power or battery capacity deficiency, the foot-operated 10 driving institute can be passed through
Driving wheel 8 is stated, then the sprocket wheel 20 is driven to rotate, and then the trailing wheel 30 is driven to rotate, moves vehicle.
Other processes and embodiment 1 of the present embodiment are similar, and details are not described herein.
