230 are equivalent to a driven swing arm, can also realize the stretching motion of step plate 100 in this case.However, in actual implementation
During, inventor's discovery is easy to appear the problem of rotary drive mechanism 300 damages.In this regard, inventor attempts in existing skill
Reason is found in art, however rarely open source literature records this phenomenon in the prior art, more records without related to explain
The reason of this existing phenomenon.Finally, inventor is by finally obtaining the reasons for the above problems after largely groping and analyze:
During step plate 100 is from hidden bit to minimum point, step plate 100, attachment base 240, active swing arm 220 and slave pendulum
The sub-assemblies of compositions such as arm gravity acting itself, the power output of rotary drive mechanism 300 is smaller at this time；And in minimum point to expansion
During position, which needs to overcome gravity acting, and the power output of rotary drive mechanism 300 at this time is larger.Therefore, exist
During entire stretching, the power output of rotary drive mechanism 300 is changed from small to big, and there are the processes of mutation, entire to retract process

In whole process, in order to overcome the moving resistance of driven slide arm 230, step plate 100, attachment base 240 and active swing arm can decompose
The gravity of the sub-assembly of 220 equal compositions and during the sliding of driven slide arm 230, moving resistance substantially constant, therefore, at this
In kind of structure basis, the power output of rotary drive mechanism 300 substantially can held stationary output so that rotary drive mechanism
300 outputs are constant, without rotary drive mechanism 300 being arranged complicated control process, while decreasing rotary drive mechanism
300, because damaging problem caused by output mutation, extend the service life of rotary drive mechanism 300, guarantee telescopic vehicle
