Embodiment

See also Fig. 5; Fig. 5 is the exploded view of embodiment of the invention slide construction 5.Slide construction 5 comprises a tooth bar (rack) 52, a gear train (gear unit) 54 and one pivot (hinge) 56.Pivot 56 comprises one first gear 561, one first cam 562, one second cam 563, a spring 564, a gim peg 565 and a shell 566.Gear train 54 comprises one second gear 541 and one the 3rd gear 542, and second gear 541 and the 3rd gear 542 are in-line gears.

See also Fig. 6; Fig. 6 is the schematic diagram in conjunction with 5 each element of slide construction among Fig. 5.First cam 562, second cam 563, spring 564 are arranged at shell 566 inside with gim peg 565, gim peg 565 is placed in the spring 564, second cam 563 slides along gim peg 565 by contacting with first cam 562, compresses spring 564 by the slip of second cam 563 again.Tooth bar 52 is meshed with second gear 541 of gear train 54, and first gear 561 of pivot 56 is meshed with the 3rd gear 542 of gear train 54.

Fig. 7 and Fig. 8 are respectively the schematic diagram of the action of slide construction 5, when tooth bar 52 moves, the rotation of meeting driven gear group 54, and then first gear 561 that drives pivot 56 rotates, because first cam 562 and first gear 561 are coaxial rotation, therefore first cam 562 and second cam 563 begin to relatively rotate.Second cam is to lower slider and compress spring 564 (as Fig. 7) in the rotating process.

When Fig. 7 state, remove the external force that imposes on tooth bar 52, change by pivot 56 and come the rotation of driven gear group 54 and moving of tooth bar 52, bounce by spring 564 makes second cam 563 upwards slide and continue and relatively rotates towards direction and first cam 562 of former rotation, first cam 562 thereby continue to rotate towards the direction of former rotation and go driven gear group 54 to rotate and tooth bar 52 moves.After spring 564 returns to original length, promptly stop all rotations and move, as shown in Figure 8.

See also Fig. 9 and Figure 10; Fig. 9 and Figure 10 are applied to the schematic diagram of slide electronic device 9 for embodiment of the invention slide construction 5.Slide electronic device 9 comprises one first housing 92 and one second housing 94, first housing 92 is provided with a display screen 91, and first housing, 92 inboards are provided with one first fastener 95, and second housing, 94 inboards are provided with one second fastener 96 and the 3rd fastener 98.The tooth bar 62 of slide construction 5 is arranged on first housing 92, and gear train 54 is arranged on second housing 94 with pivot 56.

Second fastener 96 of first fastener 95 of first housing 92 and second housing 94 fastens among Fig. 9, to fix the relative position of first housing 92 and second housing 94.After starting slide construction 5, as shown in figure 10, first fastener 95 of first housing 92 and the 3rd fastener 98 of second housing 94 fasten, to fix the final relative position that first housing 92 skids off the back and second housing 94.

When slide construction of the present invention is implemented on slide electronic device, can not take very big area, and can adjust the entire length of pivot by the suitable spring of arranging in pairs or groups, therefore the slide construction thickness that takies electronic installation can be made change according to the demand of electronic installation design, makes the design of electronic installation can meet the trend of doing littler and littler.

The above only is preferred embodiment of the present invention, and all equalizations of doing according to claim of the present invention change and modify, and all should belong to covering scope of the present invention.
