By arranging the driving member 130 between the two adjacent transmission shafts 116, the space between the two adjacent transmission shafts 116 is effectively utilized to make the shelf more compact, reduce the occupied space of the shelf, and improve the utilization rate of the space inside the refrigerator.
In an embodiment of the present application,
The driving assembly 100 drives the plate body 102 to swivel, and then leads the lifting storage-board assembly 200 to be lifted and lowered, thereby the shelf can be automatically lifted and lowered without human operation, which improves the user experience. By providing the arc groove 108 in the plate body 102, the convolute flexible cable 126 can have a smooth transition to avoid the wear and fracture of the flexible cable 126 caused by stress concentration during the flexible cable 126 wraps along the plate body 102, a load capacity of the convolute flexible cable 126 at the transition section is improved, and a service life of the convolute flexible cable 126 at the transition section is prolonged, thereby prolonging a service life of the shelf and improving a reliability of a connection between the flexible cable 126 and the plate body 102.
In an embodiment of the present application, the shelf includes two lifting storage-board assemblies 200, two driving assemblies 100 and four transmission assemblies 152, where the drive assemblies 100 are corresponded one-to-one to the lifting storage-board assemblies 200 and one drive assembly 100 drives one lifting storage-board assembly 200 to be lifted and lowered through two transmission assemblies 152. In a process of controlling two lifting storage-board assemblies 200 to be lifted and lowered, only one of the lifting storage-board assemblies 200 can be controlled to be lifted and lowered, or two lifting storage-board assemblies 200 can be controlled simultaneously to be lifted and lowered.
According to the shelf provided by the embodiments of the present application, the driving member 130 drives the transmission shaft 116 to swivel and then to lead the lifting storage-board assembly 200 to be lifted and lowered along the set direction through the transmission assembly 152, so that the shelf can be automatically lifted and lowered without human operation, which improves the user experience. By staggering the adjacent two transmission shafts 116, the adjacent flexible cables 126 are spaced at a certain distance to avoid friction between the flexible cables 126, which prolongs the service life of the flexible cable 126 and reduces the cost of use.
It should be noted that numbers of lifting storage-board assemblies 200 and driving assemblies 100 are not limited to two but can be three or more. The number of transmission assemblies 152 is twice the number of driving assemblies 100.
In an embodiment of the present application, the shelf includes two driving assemblies 100, and transmission shafts 116 of the two driving assemblies 100 are horizontal and arranged at intervals. Two ends of the transmission shaft 116 are detachably connected to the corresponding plate body 102 respectively. The transmission shaft 116 plays a role of connection between the two plate bodies 102. By connecting two plate bodies 102 through the transmission shaft 116, only one driving assembly 100 is needed to drive the two plate bodies 102 to swivel synchronously, which reduces the number of members of the driving assembly 100, simplifies the structure of the driving assembly 100, and reduces the production cost. Detachable connection between the transmission shaft 116 and the plate body 102 facilitates assembly and disassembly of the driving assembly 100 and maintenance of damaged members.
