SHELF AND STORAGE CABINET

The present application relates to the field of storage machine, and provides a shelf and a storage cabinet. The shelf includes a lifting storage-board assembly, a driving assembly and a transmission assembly. The transmission assembly includes a plate body and a flexible cable, where the plate body is connected to a transmission shaft. The plate body includes an accommodation cavity and an arc groove, where a first end-opening of the arc groove is communicated with the accommodation cavity, and a second end-opening of the arc groove is communicated with an outside of the plate body; and a first end of the flexible cable passes through the arc groove to be fixed in the accommodation cavity, and a second end of the flexible cable is configured to wrap around a mounting portion of the plate body and then connect to the corresponding lifting storage-board assembly. The shelf can be automatically lifted and lowered without human operation, which improves user experience. By providing the arc groove in the plate body, the convolute flexible cable can have a smooth transition to avoid the wear and fracture of the flexible cable caused by stress concentration during the flexible cable wraps along the plate body, a load capacity of the convolute flexible cable at the transition section is improved, and a service life of the convolute flexible cable at the transition section is prolonged, thereby prolonging a service life of the transmission assembly.
