According to the state that aforementioned Figure 11 shows, 3rd rail 18 this first rail 10 relative pulls out by continuation manual mode again, wherein, as shown in FIG. 12 and 13, pushing block 46 with the 3rd rail 18 is against the second support 140 of the synchronous piece 132 on this second rail 14, also can drive this second rail 14 synchronous shift while the 3rd rail 18 is pulled.Now, along with this second rail 14 this first rail 10 relative 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, first protuberance 112 of this moving part 106 is along longitudinal ditch 32 displacement of the guiding ditch 28 of this first rail 10, simultaneously, as shown in FIG. 13 and 14, be connected between this sliding seat 66 and this moving part 106 with this coupling assembling 108, this sliding seat 66 is made also to guide ditch 78 displacement along with the displacement of this moving part 106 along the longitudinal direction of the guiding channel 74 of this pedestal 58, until when the first protuberance 112 of this moving part 106 is driven in the horizontal ditch 34 of this guiding ditch 28 of importing, the convex body 40 of this second rail 14 can then be pressed in the second protuberance 114 upper limb of this moving part 106, the first protuberance 112 of this moving part 106 is made to keep resting in the horizontal ditch 34 of this guiding ditch 28, again, after this sliding seat 66 is also guided displacement, first pin 84a of this sliding seat 66 rests on lateral steering ditch 80 position of this guiding channel 74, and this second elastic component 68 is compressed by the crus secunda 84b of this sliding seat 66 and stores the potential energy of aforementioned second direction F2 ejection.
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 with this guide ramp 142 and is against in this release portion 26 temporarily against location, and cause this synchronous piece 132 beat displacement one angle, and make the second support 140 of this synchronous piece 132 depart from the pushing block 46 of the 3rd rail 18.According to aforesaid action, namely the 3rd rail 18 removes synchronous continuous action relation with this second rail 14, and the 3rd rail 18 this first rail 10 relative can be fully extracted, and extends the distance of pull-out with this second rail 14.
As shown in figure 15, when the 3rd rail 18 this first rail 10 relative push fold time, this the second rail 14 first taken in by 3rd rail 18,3rd rail 18 and this second rail 14 again this first rail 10 relative move into, wherein, the pushing block 46 of the 3rd rail 18 can move to the state of replying the second support 140 corresponding to 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 this second rail 14 displacement, 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 fold arrive the position of this sliding seat 66 to this fitting 152 time, the actuation ends 96 of this sliding seat 66 of this fitting 152 meeting ejection, 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 has also been displaced to second longitudinal guide path 92 place of this sliding seat 66 and has corresponded to this blocking part 88, this buckle portion 154 is made to have with blocking part 88 situation offseted subsequently, afterwards, elastic force 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 drawing the 3rd rail 18 this first rail 10 relative folds, and the state finally folded to such as Fig. 8.
On the other hand, under the collapse state shown in above-mentioned Figure 17, because this coupling assembling 108 connects this sliding seat 66 and this moving part 106, therefore this sliding seat 66 also can drive this moving part 106 displacement, and as shown in figure 18, first protuberance 112 of this moving part 106 is also left from the horizontal ditch 34 of this guiding ditch 28, and gets 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 a bolster 160 and be arranged on this first rail 10.In a preferred embodiment, this bolster 160 is fixed in pedestal 58 side of this displacement unit 50, this bolster 160 comprises one can the piston rod 162 of auto-extending, and the piston rod 162 of this bolster 160 corresponds 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 the 3rd rail 18 this first rail 10 relative, the piston rod 162 with this bolster 160 offsets this second rail 14, makes folding of this slide rail assembly more mild.
According to above explanation, namely known enhancement effect of the present invention and advantage are: oneself opened and integrated with self-close mechanism, and slide assemblies can be made automatically to open when the external force that reception one is predetermined or automatic retracting location 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 used to the present invention is described, change and the amendment of various equivalence also can be made when not departing from spirit of the present invention, therefore, as long as all will drop in the scope of the application's claims the change of above-described embodiment, modification in spirit of the present invention.
