Specifically, the first half shell 301a and the second half shell 301b have the same structure, the length, the width and the height of the two half shells are larger than those of the lifting platform 201, and a driving groove Q and a limiting groove X are distributed in the side wall of the end part of the inner cavity of the half shell, which is perpendicular to the length direction, wherein the driving groove Q is used for driving the protection component 301 in a deflection manner, and the limiting groove X is used for limiting an angle in the deflection manner. The first half-shell 301a and the second half-shell 301b are hinged to the side wall of the boss 101b by means of a hinge seat 302 located on the side wall of the lower end of the inner cavity thereof.

The rest of the structure is the same as that of example 3.

Combine to show in FIG. 1 ~ 9, this transportation platform is in the use to install for the application scene in the carriage of transport means, when unmanned aerial vehicle used up and need stop from the transportation platform on, before unmanned aerial vehicle returns, expand the transportation platform, the process is: and starting the push-up rod 102a, extending the telescopic end of the push-up rod, slowly lifting the lifting platform 201 at the top of the push-up rod, and deflecting and unfolding the stabilizing piece 102b positioned below the lifting platform 201 in the process to stably lift up the lifting platform 201. When the side wall of the lifting platform 201 does not extrude the sliding block 103b-4, under the elastic force of the lower limiting spring 103b-3, the cable 103b-5 extends towards the U-shaped lower end notch of the assembly groove 103a-2, the lower sliding block 103b-4 extends out of the lower end notch of the assembly groove 103a-2, and the upper sliding block 103b-4 is completely contracted in the upper end notch of the assembly groove 103 a-2.

Further, the driving rod 202a and the limiting rod 202b located at the two ends of the lifting platform 201, the cams T at the end portions of the driving rod 202a and the limiting rod 202b slide in the driving groove Q and the limiting groove X in the side walls of the first half shell 301a and the second half shell 301b, and generate driving force for the first half shell 301a and the second half shell 301b, so that the driving rod and the limiting rod deflect along the respective hinged positions, due to the existence of the limiting groove X, when the first half shell 301a and the second half shell 301b deflect to the maximum angle, the lifting platform 201 is lifted to the maximum height, at this time, the top of the lifting platform 201 is spacious and cannot be blocked by the protection component 301, and the unmanned aerial vehicle is convenient to park. If the unmanned aerial vehicle is not parked well, the unmanned aerial vehicle can be parked at the top of the lifting platform 201 manually, and the supports on the two sides of the bottom of the unmanned aerial vehicle are positioned in the placing notches 103a-1 of the limiting plates 103a on the two sides of the lifting platform 201.
