The shank support assembly comprises a base body and a leg support support rotationally installed on the base body, a first extension plate is installed on the leg support support in a sliding mode, a connecting rod assembly is arranged between the first extension plate and the leg support support, and the connecting rod assembly can move to pull the first extension plate to slide relative to the leg support support; a transmission assembly is arranged on the base body and comprises a driving cross rod and a linkage piece, one end of the linkage piece is hinged to the end of the driving cross rod, the other end of the linkage piece is hinged to the base body, the middle of the driving cross rod is associated with the connecting rod assembly, and when the leg support bracket rotates forwards relative to the base body, the transmission assembly can force the connecting rod assembly to move. The leg support has the advantages that through the transmission assembly and the connecting rod assembly, the leg support rotates, meanwhile, the synchronous extending function is achieved, original sliding installation of the driving transverse rod through a guide block is replaced by rotating installation of the linkage piece, when the leg support is folded, the thickness of the guide block is omitted, and the compactness of the leg support is improved.
本发明公开了一种小腿腿托总成,包括基体以及转动安装在基体上的腿托支架,腿托支架上滑动安装有第一延伸板,第一延伸板与腿托支架之间设有连杆组件,连杆组件运动能够牵引第一延伸板相对于腿托支架滑动;基体上设有传动组件,传动组件包括驱动横杆以及联动片,联动片一端铰接在驱动横杆端部,另一端与基体铰接,驱动横杆中部与连杆组件关联,当腿托支架相对于基体向前转动时,传动组件能够迫使连杆组件运动。有益效果是:通过设置的传动组件和连杆组件,实现了腿托转动的同时兼具同步延伸功能,驱动横杆由原先通过引导块滑动安装替换为由联动片转动安装,腿托收折时,省去了引导块的本身厚度,提升了腿托的紧凑度。
