Sliding rail mechanism and refrigerator with sliding rail mechanism

Abstract

The invention discloses a sliding rail mechanism and a refrigerator with the sliding rail mechanism. Each sliding rail assembly is provided with an upper rail, a middle rail and a lower rail which are in sliding fit with one another. The sliding rail mechanism further comprises a synchronous mechanism and motor assemblies. The synchronous mechanism comprises two auxiliary middle rail assemblies, steering pieces arranged on the auxiliary middle rail assemblies, tensioning pieces and fixing pieces arranged on two sliding rail assemblies, and the tensioning pieces are arranged between the fixing pieces of the two sliding rail assemblies through the steering pieces in a winding manner. Each motor assembly is provided with a first connecting end and a second connecting end which are used for winding or releasing the corresponding tensioning piece, wherein the two parts, located on the front side and the rear side of the same fixing piece, of each tensioning piece are connected to the corresponding first connecting end and the corresponding second connecting end in a winding manner. When each motor assembly works, one of the first connecting end and the second connecting end is used for tightening the corresponding tensioning piece, and the other one of the first connecting end and the second connecting end is used for releasing the corresponding tensioning piece and making the corresponding tensioning piece move. According to the sliding rail mechanism and the refrigerator, the auxiliary middle rail assemblies are additionally arranged, the steering pieces are arranged on the auxiliary middle rail assemblies, the steering pieces cannot be influenced by the gap changes of the upper rails and the lower rails, and meanwhile automatic drawer drawing is achieved.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a slide rail mechanism and a refrigerator having the same. Background technique [0002] At present, the three-section slide rails on the market mainly have the following problems in practical application: First, noise is generated during use: the existing three-section slide rails use the upper rail to run first, and when the upper rail travel distance reaches the extreme, use the upper rail Contact and collide with the limit device of the middle rail, and pull out the middle rail; also use the limit device of the middle rail and the lower rail to contact and collide, to reach the distance that the middle rail is pulled to reach the pole; and the limit device is between the upper rail and the middle rail , The noise of "peddling, pedaling" is generated during the contact and collision between the middle rail and the lower rail, which brings high-frequency noise to the user. ...

[0002] At present, the three-section slide rails on the market mainly have the following problems in practical application: First, noise is generated during use: the existing three-section slide rails use the upper rail to run first, and when the upper rail travel distance reaches the extreme, use the upper rail Contact and collide with the limit device of the middle rail, and pull out the middle rail; also use the limit device of the middle rail and the lower rail to contact and collide, to reach the distance that the middle rail is pulled to reach the pole; and the limit device is between the upper rail and the middle rail , The noise of "peddling, pedaling" is generated during the contact and collision between the middle rail and the lower rail, which brings high-frequency noise to the user

In practical application, with the increase in the number of times the three-section slide rail is used, the internal steel balls and the upper rail, lower rail, and middle rail are prone to wear, resulting in a gradual decrease in the gap distance between the upper rail and the lower rail. The distance between the rail and the base connection is extremely small. At this time, the reduction of the gap distance is likely to cause interference between the upper rail and / or the lower rail and the base connection, or even jamming

Therefore, there is a problem in the reliability of the three-section slide rail in the prior art

[0004] In addition, manually opening and closing the drawer will make the user experience not good, and the user's manual opening and closing is easy to damage the synchronization mechanism
