  • Graded lattice energy-absorbing structure, chiral cell thereof having programmable stiffness, and 3D printing method
    Patent number: 11731389
    Abstract: A chiral cell includes a cell structure. The cell structure includes an upper ring, a middle ring, a lower ring, upper connecting rods, and lower connecting rods. The upper ring and the lower ring have the same geometrical shape, and the middle ring is located between the upper ring and the lower ring. A plurality of upper connecting rods is provided; the two ends of each upper connecting rod are respectively correspondingly connected to the upper ring and the middle ring and the upper connecting rods are obliquely and uniformly distributed between the upper ring and the middle ring; a plurality of lower connecting rods is provided; the two ends of each lower connecting rod are respectively correspondingly connected to the lower ring and the middle ring and the lower connecting rods are obliquely and uniformly distributed between the lower ring and the middle ring.

  • OBJECT SORTING SYSTEM AND SORTING METHOD
    Publication number: 20220267095
    Abstract: An object sorting system includes: a storage device configured to drive an object to be sorted in the storage device to move after an object moving-out instruction is received; a transport device configured to transport the object to be sorted; and a dispatching system configured to enable the transport device to move to the storage device where the object to be sorted is located according to a storage position of the object to be sorted in the storage device, so that the object to be sorted is driven to depart from the storage device and then falls to the transport device.
