Rotation complete to fold, castor 3 is packed up by the rotation of rocking arm 2, position-limit mechanism is used to control the chassis 7 relative with side frame 1
The scope of the anglec of rotation, its angular interval be from folded bicycle deploy when side frame 1 and relative angle to the folded bicycle of chassis 7 pack up when
The relative angle of side frame 1 and chassis 7.
Shaft member 5 can be provided with side frame 1, castor 3 is rotatablely connected shaft member 5.Castor 3 includes wheel carrier and wheel body, shaft member 5
The wheel carrier on castor 3 can be passed through；First connecting rod 4 preferably connects wheel carrier, and rocking arm 2 drives first connecting rod 4 and wheel carrier to transport successively
It is dynamic；First connecting rod 4 can also connect the bearing pin of wheel body fifth wheel frame.The He of side frame 1 is completed by way of shaft member 5 passes through castor 3
Rotation connection between castor 3 so that the rotation process of castor 3 is more stable.Castor 3 in the present embodiment is to include movable castor
With the general designation of rigid castors.For movable castor also with regard to the universal wheel described in us, its structure allows 360 degree of rotations；Rigid castors
Also direction-caster is, it does not have rotational structure, it is impossible to rotate.
The end that rocking arm 2 is hinged side frame 1 can obliquely extend from connection end 6, first connecting rod 4 and connection end with respect to rocking arm 2
6 are connected backwards to the end of articulated position.Connection end 6 and rocking arm 2 can be rotated with L-shaped connection, connection end 6 with rocking arm 2, connection end
6 and rocking arm 2 can removably connect, be conveniently adjusted connection end 6 with respect to rocking arm 2 angle, so as to be set according to castor 3
The angle that first connecting rod 4 pulls castor 3 is adjusted flexibly in seated position.Connection end 6 can by trip bolt complete and rocking arm 2 can
Dismantling connection, rocking arm 2 can also be embedded in complete removably to connect by the recess being arranged on connection end 6.
As shown in Figure 1-Figure 3, the angle between connection end 6 and rocking arm 2 determines that rocking arm 2 can be relative to left side frame 12
The anglec of rotation.Connection end 6 be bonded left side frame 12 when be rocking arm 2 rotate original state, rocking arm 2 be bonded left side frame 12 when be rocking arm
The end-state of 2 rotations, rocking arm 2 during rotation, what castor 3 can be gradually pack up with chassis 7.As shown in figure 3, pin
Wheel 3 can be stowed in the frame aperture of chassis 7.
Chassis 7 can include the left chassis 71 and right chassis 72 being hinged, and side frame 1 can include the left frame 11 being hinged
With left side frame 12, left frame 11 and left chassis 71 are hinged, and left side frame 12 and right chassis 72 are hinged.Pass through the left He of chassis 71
Right chassis 72, the setting of left frame 11 and left side frame 12 and mutual cooperation so that the folded bicycle in Fig. 1 can be packed up
In the state in Fig. 3, it is easy to carry.
As depicted in figs. 1 and 2, position-limit mechanism can include the eccentric position of connecting rocker arm 2 and the eccentric position of chassis 7
Second connecting rod 8 is put, the both ends of second connecting rod 8 are respectively articulated with rocking arm 2 and chassis 7.Second company can be driven by the rotation of rocking arm 2
Bar 8 moves so that corresponding chassis 7 can move towards side frame 1, so that the folded bicycle in Fig. 1 is packed up as in Fig. 3
State.During packing up, rocking arm 2 is by driving first connecting rod 4 to pack up the state in castor 3 to Fig. 3.
Wherein, the position that first connecting rod 4 and second connecting rod 8 are hinged rocking arm 2 can be identical, and its position can such as scheme
On connection end 6 on 1 and Fig. 2.Because first connecting rod 4 and second connecting rod 8 are connected directly between on rocking arm 2, in the mistake that folding is packed up
Cheng Zhong, the stroke that first connecting rod 4 drives the stroke of the motion of castor 3 and second connecting rod 8 to drive chassis 7 to move may be long,
It is unfavorable for the preferable position that chassis 7 is retracted into flush with each other with respect to side frame 1, castor 3 with respect to side frame 1, passing through the energy of connection end 6
First connecting rod 4 and the motion formation of second connecting rod 8 and direction are enough adjusted, it is relative with respect to side frame 1, castor 3 to be conveniently adjusted chassis 7
The position that side frame 1 is finally packed up so that the folded bicycle after adjustment is packed up more rationally, and all parts coordinate more compact.
Position-limit mechanism can also include the third connecting rod of the eccentric position and the eccentric position of side frame 1 of connection chassis 7, the
One end of three connecting rods is hinged chassis 7, and the other end of third connecting rod is provided with chute, is slided in chute and be provided be hinged side frame 1
Sliding block.Packing up for folded bicycle need not shake rocking arm 2 in the present embodiment, and user is directly by manually left frame 11 and right side
The position that frame 12, left chassis 71 and right chassis 72 are hinged is lifted up, by the chute on third connecting rod and slide block structure come
Compensation side frame 1 and chassis 7 relatively rotate caused pitch difference, so as to realize packing up completely for folded bicycle.
The block 9 of side frame 1 can be abutted in its rotation process by being provided with castor 3.Block 9 is provided for limitation pin
The anglec of rotation of wheel 3, as shown in figure 1, block 9 can abut side frame 1 during castor 3 rotates, so that the He of castor 3
Rocking arm 2 will not be rotated in the steering before edge again, and its position is relatively fixed, be easy to folded bicycle deploy after stable use.Side frame 1
The magnet that can mutually adsorb with block 9, by the suction of magnet pieces, enable to folded bicycle deploy after different directions
Run more stable, castor 3 will not rotate under the resistance of bottom surface towards first connecting rod 4.
Above example is not limited to the embodiment technical scheme of itself, can be incorporated between embodiment new
Embodiment.Above example is only not limited to illustrate the technical solution of the utility model, all without departing from this
Any modification of utility model spirit and scope or equivalent substitution, it all should cover the scope in technical solutions of the utility model
It is interior.
