The state showing according to aforementioned Figure 11, continue again by manual mode, relative this first rail 10 of the 3rd rail 18 to be pulled out, wherein, as shown in FIG. 12 and 13, with the pushing block 46 of the 3rd rail 18, be against the second support 140 of the synchronous piece 132 on this second rail 14, when the 3rd rail 18 is pulled, also can drive this second rail 14 synchronous shift.Now, along with relative this first rail 10 of this second rail 14 is pulled out by the 3rd rail 18, the convex body 40 of this second rail 14 can push against the second protuberance 114 of the moving part 106 of position on this first rail 10, and along with the lasting displacement of this second rail 14, the first protuberance 112 of this moving part 106 is along longitudinal ditch 32 displacements of the guiding ditch 28 of this first rail 10, simultaneously, as shown in FIG. 13 and 14, with this coupling assembling 108, be connected between this sliding seat 66 and this moving part 106, make this sliding seat 66 also along with the displacement of this moving part 106 along longitudinal guiding ditch 78 displacements of the guiding channel 74 of this pedestal 58, until being driven, the first protuberance 112 of this moving part 106 imports the horizontal ditch 34 of this guiding ditch 28 when interior, convex body 40 meetings of this second rail 14 then be pressed in the second protuberance 114 upper limbs of this moving part 106, make the first protuberance 112 of this moving part 106 keep resting in the horizontal ditch 34 of this guiding ditch 28, again, this sliding seat 66 is also guided after displacement, the first pin 84a of this sliding seat 66 rests on lateral steering ditch 80 positions of this guiding channel 74, and this second elastic component 68 is stored by the crus secunda 84b of this sliding seat 66 compression the potential energy that aforementioned second direction F2 ejects.
On the other hand, as shown in figure 13, when the first support 138 of the synchronous piece 132 on this second rail 14 arrives the release portion 26 of this first rail 10, this first support 138 is conveniently climbed and is against in this release portion 26 and temporarily against location with this guide ramp 142, and cause this synchronous piece 132 beat displacement one angles, and make the pushing block 46 of the second support 140 disengaging the 3rd rails 18 of this synchronous piece 132.According to aforesaid action, the 3rd rail 18 and this second rail 14 removed and synchronizeed continuous action relation, relative this first rail 10 of the 3rd rail 18 can fully be pulled out, and extend the distance of pulling out with this second rail 14.
As shown in figure 15, when relative this first rail 10 of the 3rd rail 18 pushes while folding, the 3rd rail 18 is first taken in this second rail 14, the 3rd rail 18 and relative these first rail, 10 immigrations again of this second rail 14, wherein, the pushing block 46 of the 3rd rail 18 can move to the state of replying corresponding to the second support 140 of this synchronous piece 132, and the first support 138 of this synchronous piece 132 also can depart from from the release portion 26 of this first rail 10.On the other hand, after these the second rail 14 displacements, the convex body 40 of this second rail 14 also no longer compresses the second protuberance 114 of this moving part 106.
As shown in FIG. 16 and 17, when the 3rd rail 18 this first rail 10 relative to this second rail 14 folds while arriving the position of these sliding seat 66 to this fitting 152, the actuation ends 96 of these fitting 152 these sliding seat 66 of meeting ejection, the first pin 84a of this sliding seat 66 is departed from from the lateral steering ditch 80 of this guiding channel 74 immediately, and the buckle portion 154 of this fastener 148 be also displaced to this sliding seat 66 second longitudinal guide path 92 places and corresponding to this blocking part 88, make this buckle portion 154 there is subsequently with blocking part 88 situation offseting, afterwards, the elastic force that sees through the second direction F2 of this second elastic component 68 is applied to this sliding seat 66, the blocking part 88 of this sliding seat 66 is just connected to the buckle portion 154 of this fastener 148 and relative this first rail 10 of drawing the 3rd rail 18 folds, and finally fold to as the state of Fig. 8.
On the other hand, under the collapse state shown in above-mentioned Figure 17, because this coupling assembling 108 is to connect this sliding seat 66 and this moving part 106, therefore this sliding seat 66 also can drive this moving part 106 displacements, and as shown in figure 18, the first protuberance 112 of this moving part 106 is also left from the horizontal ditch 34 of this guiding ditch 28, and get back to longitudinal ditch 32 of this guiding ditch 28.Wherein, the elastic force of this first spring 110 also provides an auxiliary active force, makes the swing of this moving part 106 more smooth and easy.
As shown in FIG. 19 and 20, also comprise that a bolster 160 is arranged on this first rail 10.In a preferred embodiment, this bolster 160 is fixed in pedestal 58 1 sides of this displacement unit 50, this bolster 160 comprise one can auto-extending piston rod 162, and the piston rod 162 of this bolster 160 is corresponding to this second rail 14, and form a cushion stroke with the extension elongation of this piston rod 162, when this second rail 14 is folded with relative this first rail 10 of the 3rd rail 18, with the piston rod 162 of this bolster 160 this second rail 14 that offsets, make folding of this slide rail assembly more mild.
According to above explanation, known enhancement effect of the present invention and advantage are: oneself is opened with self-close mechanism and integrated, and can make slide rail parts can automatically open or automatic retracting location when receiving a predetermined external force in good time.
Although the present invention describes with reference to current specific embodiment, but those of ordinary skill in the art will be appreciated that, above embodiment is only for the present invention is described, in the situation that not departing from spirit of the present invention, also can make variation and the modification of various equivalences, therefore, as long as the variation of above-described embodiment, modification all will be dropped in the scope of the application's claims within the scope of connotation of the present invention.
