Automatic lifting shelf device and refrigerator

Abstract

The invention provides an automatic lifting shelf device. The device comprises a shelf and connecting rods fixedly connected with the shelf, and further comprises gear motors; the connecting rods comprise ball screw assemblies, and the ball screw assemblies comprise ball screws, ball nuts and transmission gears, wherein the ball screws and the ball nuts are matched with one another, and the transmission gears are fixed at the bottoms of the ball screws; the transmission gears are in meshed connection with the gear motors; and first through holes are formed in the shelf, the ball nuts are inserted into the first through holes and are fixed with the shelf, and the ball screws rotate under the action of the gear motors so as to drive the shelf to ascend or descend through the ball nuts. The invention further provides a refrigerator, wherein the refrigerator is provided with the automatic lifting shelf device. According to the automatic lifting shelf device and the refrigerator, the structure is simple, and stepless automatic adjustability can be realized on the position of the shelf.

Description

technical field [0001] The invention relates to a storage device, in particular to an automatic lifting shelf device and a refrigerator equipped with the automatic lifting shelf device. Background technique [0002] Along with the raising of people's living standard, refrigerator is widely used. At present, the internal shelves of most of the refrigerators sold in the market are in fixed positions, and the placement of the shelves can only be adjusted within a limited range, and the adjustment distance is fixed, which reduces the utilization of the internal space of the refrigerator, resulting in Part of the space is wasted, especially on large-volume refrigerators, which is more common. And when the position of the shelf needs to be adjusted, the shelf needs to be taken out completely from the refrigerator, and usually the various items placed on the shelf need to be taken out before the shelf is taken out, and then the shelf is placed in the desired position. It is cumbe...
