The both sides that are used for lower guideway 2 length directions that fix with car floor respectively constitute a roller guide chamber 22 through bending, and on the diapire in the lower guideway chamber 21 of lower guideway 2, offer a pair of feed screw nut's fixed orifice 23 and respectively be equipped with a positive stop lug boss 211 at the two ends of the chamber in lower guideway chamber 21 diapire, be used for the following roller stand that also will describe 5 spacingly, lower guideway chamber 21 prevents to scurry out.

The main points of the technical scheme that provides as the utility model, to be used for ordering about upper rail 1 and take driving device 3 that automotive seat 6 move and be contained in that common to cooperate the cavity volume that forms be die cavity by aforesaid upper and lower guide rail chamber 11,21, and by upper and lower guide rail 1,2 its enforcement be covered and protect.Preferably but not the structure of the driving device 3 that definitely is limited to is as follows: comprise worm and gear box body 31, worm gear 32, worm screw 33, screw mandrel 34 (also can claim leading screw), on the screw mandrel, following seat 35,36, screw mandrel support sleeve 37 and feed screw nut's seat 38, with present location status shown in the drawings is example (as follows), worm and gear box body 31 is configured in, lower guideway chamber 11,21 the right-hand member of the common cavity volume that forms, worm gear 32 pivots are arranged in the worm and gear chamber 311 of worm and gear box body 31, specifically: the worm-wheel shaft 321 of worm gear 32 is supported on the worm and gear box body 31 rotationally by pair of bearings 3211, worm screw 33 is supported on the worm and gear box body 31 rotationally by corresponding bearing equally, with aforesaid worm screw 32 engagements, and worm screw 33 is in transmission connection with actuating device 4.The right-hand member of screw mandrel 34 extend in the worm and gear chamber 311 and fixes with described worm gear 33, just worm gear 33 is fixed on the right-hand member of screw mandrel 34, (formation lead screw pair or title lead screw transmission pair) matches with feed screw nut's seat 38 at the middle part of screw mandrel 34, the screw mandrel spindle nose 341 of the left end of screw mandrel 34 is inserted in the screw mandrel spindle nose hole 372 of right-hand member of screw mandrel support sleeve 37, left end at screw mandrel support sleeve 37 has a narrow supporting neck that contracts 371, and supporting neck 371 matches with the upper and lower seat 35,36 of screw mandrel.The bottom at the screw mandrel seat of honour 35 is processed with one first semicircle neck groove 351, and the top of following 36 of screw mandrel is processed with one second semicircle neck groove 362, first, second semicircle neck groove 351,362 matches and forms a complete supporting neck hole, after hole, the aforesaid screw mandrel seat of honour 14 is inserted at the screw mandrel seat of honour 35, match, thereby the supporting neck 371 of screw mandrel 37 is limited with following 36 of screw mandrel.Shown in accompanying drawing, each design has one first jump ring hook groove 361 on the wall body of the corresponding both sides of following 36 of screw mandrel, the aforesaid first jump ring hook 1211 hooks together in the first jump ring hook groove 361, each design has one second jump ring hook groove 312 in the corresponding both sides of the outer wall of worm and gear box body 31, and the aforesaid second jump ring hook, 1311 hooks are put in the second jump ring hook groove 312.By above-mentioned explanation as can be known, realize being connected by first, second jump ring 121,131 with driving device 3.The bottom of aforesaid feed screw nut's seat 38 is furnished with feed screw nut's seat cushion 381, on feed screw nut's seat cushion 381, offer a pair of fixing screw hole 3811, it is fixing with lower guideway 2 with screw mandrel bacterium nut seat 38 to take nest 232 with a pair of fix screw of illustrating among the figure 231, specifically: fix screw 231 is passed in the screw hole of the bottom that is screwed into feed screw nut's seat 38 behind the nest hole 2321 that is embedded at the nest 232 on feed screw nut's seat fixed orifice 23 and the fixing screw hole 3811.

Continue to see accompanying drawing, a roller stand 51 is located in the lower guideway chamber 21, the left end of the corresponding both sides of the length direction of this roller stand 51 respectively is provided with a pair of roller 51, and the right-hand member of the both sides of the length direction of roller stand 51 respectively is provided with one piece of roller 51, and the middle part at the length direction of roller stand 5 offers feed screw nut's seat slot to make way 52, the both sides of the length direction of roller stand 5 are arranged in aforesaid roller guide chamber 22, and the rolling surface 151 of aforesaid roller guide 15 (bottom surface of roller guide 15) matches with roller 51.

Still see accompanying drawing, actuating device 4 above-mentioned comprises motor 41 and the motor fixing seat 42 with rotating function, motor 41 is fixed on the motor fixing seat 42, and motor fixing seat 42 is taken on the underframe that motor 41 is fixed on automotive seat 6, as the applicant in the above as described in, because of upper and lower guide rail 1,2 is in pairs configuration, so the motor shaft 411 of motor 41 has two, is in transmission connection with a pair of driving device 3 respectively.Axle head at motor shaft 411 has the square toes 4111 of connection, and it is interior and matched with worm screw 33 worm screw square toes axis holes 331 that connection square toes 4111 extend into worm and gear chamber 311.

The applicant sketches principle of work of the present utility model in conjunction with the accompanying drawings, when the motor 41 of actuating device 4 is worked, driving worm screw 33 by motor shaft 411 rotates, because worm screw 33 is meshed with worm gear 32, therefore drive worm gear 32 motions by worm screw 33, be connected mutually with worm gear 32 owing to screw mandrel 34 again, therefore by worm gear 32 screw mandrel 34 is rotated, also owing to upper rail 1 is connected with following 36 of the screw mandrel of driving device 3 by first jump ring 121, and be connected with worm and gear box body 31 by second jump ring 131, and since the screw mandrel seat of honour 35 take upper rail 1 and match with following 36 of screw mandrel, therefore when screw mandrel 34 motions, upper rail 1 portable automotive seat 6 moves, and realizes that the front and back position of automotive seat 6 is regulated, when motor 41 quits work, automotive seat 6 just are in lockup state.In aforesaid working process, motor 41 cw work, screw mandrel 34 clickwises, automotive seat 6 reaches, on the contrary move then.

In sum, because driving device 3 was set at by 11,21 common cooperations in the cavity volume (wall chamber) that forms of upper and lower guide rail chamber, therefore, trifle in the world or foreign matter can not invaded driving device 3, and can save area occupied ideally, in addition, the lubricating grease of driving device 3 can not drip to car floor, does not have the anxiety of twice pollution.
