Problems solved by technology

[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

Embodiment approach

[0068]Here, on the basis of the three-section slide rail in the prior art, the auxiliary middle rail assembly 5b is added, and the steering piece 21 of the synchronous mechanism 2 is arranged on the auxiliary middle rail assembly 5b, and the steering piece 21 and the three-section slide rail are not connected to each other. Contact, that is to say, at this time, the moving tracks of the steering member 21 and the tension member 23 do not overlap with the sliding tracks of the three-section slide rails, even if the gap between the upper rail 11 and the lower rail 13 is reduced due to wear, it does not overlap. It will affect the normal operation of the steering member 21 in the synchronous mechanism 2, and can effectively solve the problem of interference between the steering member 21 and the upper rail 11 and / or the lower rail 13 in the prior art. In addition, this embodiment can utilize the common three-section slide rail structure in the market, and only needs to cooperate w...

Abstract

A slide rail mechanism and refrigerator having same. Each slide rail component (1) is provided with an upper rail (11), a middle rail (12), and a lower rail (13) slidingly fitting each other. The slide rail mechanism also comprises a synchronization mechanism (2) and a motor component (3). The synchronization mechanism comprises two auxiliary middle rail components (5), bogie elements (21) provided at the auxiliary middle rail components (5), tensioning elements (23), and retaining elements (22) provided at either slide rail component (1). The tensioning elements (23) run between the retaining elements (22) of either slide rail component (1) via the bogie elements (21). The motor component (3) is provided with a first connecting extremity (31) and a second connecting extremity (32) for winding or releasing the tensioning elements (23). Two parts of the tensioning elements (23) arranged at either the front or rear side of a same retaining element (22) are wrapped on and connected to the first and second connecting extremities. When working, the motor component (3) retracts the tensioning elements (23) via either of the first and second connecting extremities and releases the tensioning element (23) via the other, thus moving the tensioning elements (23). The slide rail mechanism has added thereto the auxiliary middle rail components (5) and provides the bogie elements (21) on the auxiliary middle rail components (5), the bogie elements (21) are not affected by a change in corresponding gaps between the upper rails (11) and the lower rails (13), at the same time, automatic pull-out is implemented for a drawer.

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. ...
