A kind of accommodation ladder platform fold mechanism being applied to above-mentioned Foldable pedal, comprise pedal trace and some grades of Foldable pedals, described some grades of Foldable pedals are arranged in gangway ladder door, described pedal trace is unified hinged with the same position of Foldable pedal at different levels, but except the hinged place of the hinged place of the first strut member and gangway ladder door and the 3rd strut member and gangway ladder door, pedal trace and the first strut member, the second strut member, the 3rd strut member, gangway ladder door form planar linkage mechanism jointly.
The connection of pedal trace and Foldable pedal at different levels in above-mentioned accommodation ladder platform fold mechanism is described in detail:
The first situation, the 3rd strut member of every grade of Foldable pedal and the hinged rear of gangway ladder door also have one section of extension, and described pedal trace is hinged on this extension.
The second situation, the first strut member of every grade of Foldable pedal and the hinged rear of gangway ladder door also have one section of extension, and described pedal trace is hinged on this extension.
The third situation, described pedal trace is when wherein a strut member is hinged with the first strut member, the second strut member, the 3rd strut member, and its hinge-point is between this strut member and two hinged places of all the other strut members.
4th kind of situation, described pedal trace is hinged on the hinged place between the first strut member, the second strut member or is hinged on the hinged place between the second strut member, the 3rd strut member.
The corresponding every hinged strut member of one-level Foldable pedal of described pedal trace.
In sum, owing to have employed technique scheme, the beneficial effects of the utility model are: under the driving of outside actuating unit, and drive link drives Foldable pedal at different levels link folding and launch, thus be conducive to increasing the utilized space in cabin, increase the aesthetic property of indoor environment.
