Furthermore, sometimes because there is unavoidable installation tolerance between the carrier 116, the first rail 102, the second rail 104 and the cabinet 118, or under the requirements of certain specific specifications, the carrier The width W of 116 is very wide. Therefore, when the user intends to pull out the carrier 116 from the stowed position in the cabinet body 118 , if the user exerts a pull-out force F, it is more biased towards a side of the carrier 116 . If it is on the side, it may cause the second rail 104 of the slide rail assembly 100 on the other side of the load 116 to tilt slightly at an angle A (such as Image 6 shown)
In this case, it may cause the locking portion 112 of the second rail 104 to be released from the actuating portion 114 of the driving member 108, which will cause the second rail 104 to be retracted from the extended position P again afterwards. The auto-collapse function of the

Embodiment Construction
[0034]Such asFigure 7 versusFigure 8 As shown, a sliding rail assembly 20 of an embodiment of the present invention includes a first rail 22, a second rail 24, and a drive mechanism 25, preferably, further comprising a third rail 26 actively mounted in the first One rail 22 is between the second rail 24, which is used to increase the displacement stroke of the second rail 24 relative to the first rail 22. Among them, the first rail 22 has a longitudinal length with the third rail 26.
[0035]The second rail 24 includes a first wall 28a, a second wall 28b and a longitudinal wall 30 connected between the first wall 28a and the second wall 28b. The second rail 24 has a front portion 32 and a rear portion 34. Further, the second rail 24 includes a card scaffina 36, preferably, which is located located adjacent the rear portion 34. The card scales feature 36 are, for example, a slot or a gap, or the groove or the gap has a side wall W as an outline.
[0036]The drive mechanism 25 is located ...

The invention relates to a sliding rail assembly and its driving mechanism. The sliding rail assembly includes a first rail, a second rail and a driving mechanism. The second rail can be displaced relative to the first rail, and the second rail includes a locking feature; the driving mechanism is located on the first rail, and the driving mechanism includes a housing, a movable part, an actuating structure and an elastic part . The movable part can move relative to the housing; the actuating structure is located on the movable part; the elastic part is used to provide elastic force to act on the movable part; wherein, the actuating structure includes a first part and a second part; wherein , the first portion is used for engaging the locking feature of the second rail, and the second portion is used to prevent the locking feature of the second rail from being released from the first portion.
Description
Technical field[0001]The present invention relates to a slide rail, particularly a slide rail assembly that can be lifted drive mechanism for reliability of the rail.Background technique[0002]Such asfigure 1 As shown, a slide assembly 100 includes a first rail 102, a second rail 104, and a drive mechanism 106. Wherein, the second rail 104 can be used to carry a carrier relative to the first rail 102; the drive mechanism 106 is mounted in the first rail 102, and the drive mechanism 106 is used to provide the second rail 104. Combine features.[0003]Such asfigure 2 versusimage 3 As shown, the second rail 104 is pulled out of an extended position P relative to the first rail 102. Among them, the driving member 108 of the drive mechanism 106 is in a card shade, and is used to temporarily maintain the elastic force of the elastic member 110. When the second rail 104 is joined to the end segment from the extension position P, the one card portion 112 of the second rail 104 is capable of cl...
