Intelligent lifting shelf and refrigerator

Abstract

The invention discloses an intelligent lifting shelf and a refrigerator, wherein mounting grooves are formed in the upper surfaces of upright posts; rectangular channels are respectively arranged on the two opposite side surfaces of each mounting groove; a motor is arranged in the middle of a chassis; a lead screw is arranged on the motor through a coupler; a first transmission rod and a second transmission rod are movably arranged on a bearing block; crankshaft connecting rods are respectively arranged at the two ends of the first transmission rod and the second transmission rod; and the lower end of each crankshaft connecting rod passes through the rectangular channel and is connected with the lifting platform. According to the intelligent lifting shelf and the refrigerator in the invention, CCD cameras are arranged in the refrigerator in an array manner, so that the sizes of the stored objects are intelligently identified and judged, the required lifting height is calculated, the storage space of the objects to be stored is automatically adjusted and adapted, and intelligent lifting can be realized without manual lifting or manual reminding; bottom feet are driven to lift in theupright posts through the cooperation of the motor, the transmission rods and the crankshaft connecting rods, and a shelf board is driven to lift; and the lifting motion of the shelf is smooth and synchronous, the gravity eccentricity problem of the objects is basically not influenced, and the operation is stable.

Description

technical field [0001] The invention belongs to the technical field of refrigerators, in particular to an intelligent lifting shelf and a refrigerator. Background technique [0002] With the needs of users' individual needs, there are more and more types of stored items, and the sizes of the items are different. However, the positions of the shelves used to store items in existing refrigerators, especially refrigerators, are basically fixed or at fixed intervals and intervals. Internal adjustment, the height and position of the shelf cannot be adjusted at will, and the adjustment is troublesome, laborious and time-consuming. There are some existing patents. Although the lifting function of the shelf is realized to a certain extent, the lifting structure itself is relatively simple. Generally, it is a single or two-sided lifting structure. Due to the uneven center of gravity of the items, the shelf will be tilted, bent, or even deformed after long-term use. And other problem...

Problems solved by technology

[0002] With the needs of users' individual needs, there are more and more types of stored items, and the sizes of the items are different. However, the positions of the shelves used to store items in existing refrigerators, especially refrigerators, are basically fixed or at fixed intervals and intervals. Internal adjustment, the height and position of the shelf cannot be adjusted at will, and the adjustment is more troublesome, laborious and time-consuming

There are some existing patents. Although the lifting function of the shelf is realized to a certain extent, the lifting structure itself is relatively simple. Generally, it is a single or two-sided lifting structure. Due to the uneven center of gravity of the items, the shelf will be tilted, bent, or even deformed after long-term use. And other problems, resulting in poor blockage of the device, high noise, short life and other problems

Moreover, due to the lack of precise control of the stroke, the stroke can only be controlled manually or semi-automatically, and precise control cannot be achieved. After the shelf is lifted and lowered, there will be a problem of too large or too small reserved space, which is not conducive to maximizing the use of storage space.
