Cross-brace skeleton 211 is assembled with 4 slides/rolls of support platform, for being moved in the support platform and lifting process of fixed-area
The cross-brace skeleton 211 of dynamic change is adapted to.Specifically, the global shape size of support platform 4 and polygon scissor mould
The polygonal profile of block is adapted, and is connected through the hinge and formed by the folded sheet of the small polygon of polylith, support platform 3 can pass through hinge
Chain is folded, in order to by small space, improve the passability of support platform.
In practical applications, the side number of polygon scissor module 2 of the invention, the tricks of electromagnetic drive mechanism and installation side
Formula etc. is there are various deformation structure, as the scissors mechanism 21 of polygon scissor module 2 can be according to actual conditions along triangle, four sides
The sideline arrangement of the regular polygons such as shape, pentagon or hexagon, to improve the bearing capacity of device to a certain extent, and with
The increase of regular polygon side number can install more multigroup electromagnetic drive mechanism, can largely improve the carrying of device entirety
Ability and non-deformability.
As shown in Fig. 6 a, 6b and 6c, during the lifting gear of specifically used the present embodiment, as needed, the suitable number of plies is selected
Polygon scissor module, an appropriate number of electromagnetic drive mechanism and screw mandrel drive mechanism；If it is necessary, Distance-sensing can be used
Device measures the distance of cross-brace skeleton in real time, and feeds back to the controllers such as microcontroller, realizes accurate control electromagnetic mechanism in real time
The parameter such as electric current carry out the lifting precision of accurate control mechanism.In actual work, first device will be schemed using screw mandrel drive mechanism 3
Electromagnetic drive mechanism works to avoid initial again after the polygon scissor module of folding retracted state is increased to certain altitude in 6a
The locking phenomenon in stage, after reaching the height shown in Fig. 6 b, then starts electromagnetic drive mechanism 22；When device is needed a certain
When highly suspending, the screw latching characteristics of screw mandrel drive mechanism 3 can be used to be locked, to adapt to different use environments.
Finally illustrate, the above embodiments are merely illustrative of the technical solutions of the present invention and it is unrestricted, although with reference to compared with
The present invention is described in detail in good embodiment, it will be understood by those of ordinary skill in the art that, can be to the skill of the present invention
Art scheme technical scheme is modified or replaced equivalently, without departing from the objective and scope of technical solution of the present invention, it should all cover at this
Among the right of invention.
