Such as Fig. 9 to Figure 11, it is the principle explanation of linkage unit in the present invention 6 below：

Released state：As bar magnet 60 has magnetic, therefore when driving link band lower moving guide 61, can be with by bar magnet 60 Fairlead 62 is smoothly driven together to be rotated, now whole linkage unit is that in one, i.e., whole linkage unit is rotated, But bar magnet 60 is not snapped in stopper slot so that driving link is only capable of band lower moving guide 61 and rotates, and linkage unit is not by driving link Lock with driven member so that driving link dallies.

Locking state：Fixed guide 61 is interpreted as (when there is relative motion between guide 61 or guide plate 620 Or guide plate 620, another motion), as bar magnet 60 is located between rotation slot inwall and flat side 610, with guide 61 Rotate, bar magnet is moved to the edge on flat side 610, bar magnet 60 extrude on rotation slot inwall by the edge on flat side 610 always, when turn When moving stopper slot 64, in the embedded stopper slot 64 of bar magnet so that bar magnet 60, flat side 610 and stopper slot 64 constitute a locking Structure, now entirely linkage unit is no longer individually rotated, but driving link and driven member are carried out locking linkage so that driving link Driven member synchronous axial system can be driven.

Hereinafter the locking of arrangement of clutch and detached process in perambulator are driven for the present invention is double dynamical：

1. the locking state in start-up course：Children are sitting on perambulator, and the body weight of children drives pedal spindle that gravity presses On fairlead 62 so that in starting, pedal spindle 1 has the frictional force for pushing generation to perambulator to fairlead 62, when now Step pedal to drive pedal spindle 1 to rotate or driving link is rotated with lower moving guide 61 by driver 2, fairlead 62 is in Frictionally secure state so that linkage unit 6 is changed into locking state from released state.

2. the locking state during travelling：When the rotating speed of pedal spindle 1 or driver 2 is more than the rotating speed at existing power drive end When, as the effect of the frictional force in accelerator can be exaggerated, therefore the linkage unit 6 of the bigger side of speed can be by separating State is changed into locking state, therefore the bigger side of relative velocity can be in locking state, and the locking time is to enter the moment for accelerating Row locking.

3. the released state during travelling：Once the larger side linkage unit 6 of rotating speed was changed into locking in the moment for accelerating State, the larger drive end band motor car wheel speed-raising of speed are rotated, and the speed of wheel 7 will rise, and in the moment that wheel accelerates, make The relatively low the opposing party's linkage unit 6 of rotating speed unlocks state, make bar magnet 60 return to medium position by the one end on flat side 610, When between driving link and driven member on wheel be speed difference maintain one it is stable at the uniform velocity interior when, the position of bar magnet is no longer sent out Changing, no longer clamping are locked.

Therefore according to above-mentioned principle, the toy baby-carriage of the double dynamical driving in the present invention can obtain following application：

1. the fast and flexible switching of two kinds of dynamic modes；

2. solve the problems, such as that power driver climbing dynamics is not enough；

3. when preventing the turning of toy baby-carriage, outboard wheel is skidded brought rollover hidden danger.

The above makes the preferred embodiment of the present invention, for the person of ordinary skill of the art without departing from this On the premise of bright principle, some modifications and improvement can also be made, these also should be regarded as protection scope of the present invention.
