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 as Figure 7 and Figure 8 As shown, a slide rail assembly 20 according to an embodiment of the present invention includes a first rail 22, a second rail 24 and a driving mechanism 25, preferably, also includes a third rail 26 movably mounted on the first rail Between the first rail 22 and the second rail 24 , the third rail 26 is used to increase the displacement stroke of the second rail 24 relative to the first rail 22 . Wherein, the first rail 22 , the second rail 24 and the third rail 26 all have a longitudinal length.
[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 . Furthermore, the second rail 24 includes a detent feature 36 , preferably, the detent feature 36 is located adjacent to the rear portion 34 . The locking feature 36 is, for example, a groove or a notch, and the groove...

The invention discloses a slide rail assembly, and a driving mechanism thereof. The slide rail assembly comprises a first rail, a second rail, and the driving mechanism; the second rail is capable ofmoving with relative to the first rail, and comprises a clamping structure; the driving mechanism is arranged on the first rail and comprises a housing, a movable member, a driving structure, and an elastic component; the movable member is capable of moving with relative to the housing; the driving structure is arranged on the movable member; the elastic component is used for providing the movablemember with elastic force; the driving structure comprises a first part and a second part; the first part is used for clamping of the clamping structure of the second rail, and the second part is used for preventing declamping of the clamping structure of the second rail from the first part.
Description
technical field [0001] The invention relates to a slide rail, in particular to a slide rail assembly capable of improving the reliability of a drive mechanism used in the slide rail. Background technique [0002] Such as figure 1 As shown, a slide rail assembly 100 includes a first rail 102 , a second rail 104 and a driving mechanism 106 . Wherein, the second rail 104 can be displaced relative to the first rail 102 to carry a load; the driving mechanism 106 is installed on the first rail 102, and the driving mechanism 106 is used to provide the second rail 104 with automatic Collapse function. [0003] Such as figure 2 and image 3 As shown, the second rail 104 is pulled out in an extended position P relative to the first rail 102 . Wherein, a driving member 108 of the driving mechanism 106 is in a locked state for temporarily maintaining the elastic force of an elastic member 110 . When the second rail 104 is retracted from the extended position P to a retracting dir...
