The invention discloses an undercarriage folding and unfolding structure, and relates to the technical field of undercarriages. The machine comprises a machine belly, a storage bin is formed in the machine belly, machine wheels are hinged to the interior of the storage bin, driving sliding grooves are symmetrically formed in the inner side of the storage bin, and driving sliding blocks are slidably connected to the interiors of the driving sliding grooves. Through cooperative use of the driving sliding block, the transmission assembly and the driven assembly, the driving assembly can be started to drive the driving sliding block to move in the length direction of a driving sliding groove, and a follow-up rack drives a driven rod to move in the length direction of a driven sliding groove; and meanwhile, a driving sliding block drives a transmission assembly to drive a machine wheel to rotate around a hinge shaft, so that one end of the machine wheel is ejected out of the interior of a storage bin to make contact with the ground while the cover plate is driven to retract into the storage groove, and the machine wheel is driven to rotate around the hinge shaft. The driving process of the airplane wheel and the cover plate is effectively simplified, and the occupied space of the driving mechanism is saved.

    本申请公开了一种起落架收放结构,涉及起落架技术领域。本申请包括机腹,机腹的内部开设有收纳仓,收纳仓的内部铰接有机轮,且收纳仓的内侧对称开设有驱动滑槽,驱动滑槽的内部滑动连接有驱动滑块。本申请通过设置驱动滑块与传动组件、从动组件的配合使用,使得启动驱动组件可以驱动驱动滑块沿着驱动滑槽的长度方向移动,并使得随动齿条带动从动杆沿着从动滑槽的长度方向进行移动,从而驱动盖板沿着平行于收纳槽的方向进行移动,同时使得驱动滑块驱动传动组件带动机轮绕铰接轴进行旋转,以此便于驱动盖板缩入收纳槽内部的同时,使得机轮的一端顶出收纳仓的内部与地面接触,有效简化了机轮与盖板的驱动流程,节约了驱动机构的占用空间。
