The rear portion of right connecting rod 5 is rotated around the wheel shaft of off hind wheel component 103 to D directions.Simultaneously as children's gravity, children and Che
Frame 100 moves downwardly together, and 1 and second axis 2 of first axle moves down.Since the center of gravity of children and vehicle frame 100 are to the left, so
The amplitude that first axle 1 moves down is much larger than the amplitude that the second axis 2 moves down.Ultimately form the left side of vehicle frame 100 lower section to the left
Tilt, and there is the trend being upturned on right side.Due to left drive shaft 1, right transmission shaft 2, reverse drive mechanism 3, left connecting rod 4,
The effect of right connecting rod 5 and elastic mechanism 104, lower section is inclined to the left while can protect all the time for the vehicle frame 100 of child's tricycle
Children and 100 relative equilibrium of vehicle frame are held, are not in the situation of overturning.
The process of children's torso to Right deviation is similar with "Left"-deviationist, is not unfolded to be described in detail herein.
Vehicle frame 100 has larger inclination displacement when the utility model can realize children's lateral tilting, makes children
With can be obtained during child's tricycle the experience sense of inclination by, child's tricycle structure it is novel, using interesting.Meanwhile Left Drive
Axis 1, right transmission shaft 2, reverse drive mechanism 3, left connecting rod 4, right connecting rod 5 and elastic mechanism 104 can ensure child's tricycle
Relative equilibrium and stability, there is the safety for rolling and ensureing that children use on the basis of experience in child's tricycle.At the very moment
Virgin body is ajusted when being moved in reset, center of gravity, and vehicle frame 100 returns positive reset under the action of spring part 9.
In addition, on the basis of above-described embodiment, driving mechanism can be converted.For example, the driving mechanism is
Tape handler.The tape handler include be installed on the driving pulley on the output revolving shaft of the motor 8, with before
The driven pulley that wheel assembly 101 is coaxially disposed and the flexible transmission belt being stretched on driving pulley and driven pulley.Such a side
The driving mechanism of formula is similar with the working method of driving mechanism in the above embodiments, and details are not described herein again.
As described above, we are illustrated fully according to the objective of the utility model, but the utility model not limits to
In above-described embodiment and implementation.The scope that the practitioner of correlative technology field can permit in the technological thought of the utility model
It is interior to carry out different change and implementation.
