Described seat leg holder regulating mechanism, its further characteristics be, first motion thread of out screw rod is the outside thread that is used for transmission, and second motion thread is the negative thread that is used for transmission; Second transmission component comprises screw mandrel in, and screw mandrel has the outside thread that is used for transmission in this, and outside thread of screw mandrel and second motion thread of out screw rod form second screw thread pair in this; First transmission component comprises a drive leader, and first end of drive leader provides and cooperates the negative thread that forms first screw thread pair with first motion thread.
Described seat leg holder regulating mechanism, its further characteristics are, second end of drive leader and interior slide rail articulate, second transmission component also comprises a coupling spindle, this out screw rod connects support by first and is connected with this coupling spindle, the two ends of this coupling spindle connect two second respectively and connect support, and this two second connections support is connected rotationally with two described external slide rails respectively, and this two external slide rail is connected with interior slide rail in the both sides of interior slide rail respectively.
Described seat leg holder regulating mechanism, its further characteristics are, drive leader is formed by connecting by two lamellar bodies, first end of drive leader has square opening, be placed with square contiguous block in this square opening, this square contiguous block has the described negative thread that first end of drive leader provides, and out screw rod passes this square contiguous block and forms described first screw thread pair, and the part of out screw rod and interior screw mandrel extend between two lamellar bodies of drive leader.
Described seat leg holder regulating mechanism, its further characteristics are that this seat leg holder regulating mechanism also comprises the motor that drives out screw rod.
The beneficial effects of the utility model are: because the pitch of first screw thread pair is greater than the pitch of second screw thread pair, when out screw rod rotates towards predetermined direction, in, external slide rail will be according to specific path of motion motion, promptly the moving velocity of first transmission component is greater than the moving velocity of second transmission component, produce slide relative and interior slide rail between interior slide rail and the external slide rail and can promote the super predetermined direction rotation of external slide rail, leg holder parts are set on interior slide rail, thereby when releasing the leg holder, also the leg holder is adjusted at proper angle, hold up occupant's shank, change occupant's the attitude of taking, and when regaining the leg holder, also the leg holder is turned to stowed position.

The specific embodiment
As shown in Figures 1 to 4, seat leg holder regulating mechanism comprises motor 1, out screw rod 3, interior screw mandrel 21, drive leader 36, two external slide rails 42 and interior slide rail 43.Motor 1 disposes retarder, and motor 1 is connected with out screw rod 3 by retarder, rotates to drive out screw rod 3.
As Fig. 9 and shown in Figure 10, out screw rod 3 has outside thread that is used for transmission and the negative thread that is used for transmission.Drive leader 36 is that two parallel lamellar bodies are formed by connecting, and an end of drive leader 36 provides square opening, and square contiguous block 360 is placed in the square opening.Square contiguous block 360 has negative thread.Out screw rod 3 passes square contiguous block 360, the negative thread engagement of the outside thread of out screw rod 3 and square contiguous block 360, and form first screw thread pair, when out screw rod 3 rotated, drive leader 36 moved thereupon.After out screw rod 3 passes square contiguous block 360, between two lamellar bodies of drive leader 36, extend.
Get back to Fig. 1 to Fig. 4, simultaneously with reference to Fig. 5 and Fig. 6, an end of drive leader 36 is connected with rotating shaft 362 respectively rotationally with interior slide rail 43, and promptly drive leader 36 and interior slide rail 43 articulate.
Simultaneously referring to figs. 1 through Fig. 4, Fig. 7 and Fig. 8, an end of out screw rod 21 be connected support 210 and connect, coupling spindle 211 passes and connects support 210, the two ends of adapter shaft 211 also are connected support 212 respectively and connect with two, two connect support 212 is connected rotationally with two external slide rails 42 respectively.Drive leader 36 is in the process that moves, and slide rail 43 moves in driving, and interior slide rail 43 is different with external slide rail 42 moving velocitys, and therefore, interior slide rail 43 and external slide rail 42 can produce and relatively move, and sway simultaneously.As shown in figures 1 and 3, interior slide rail 43 can be held shank in the maximal regulated position, is hidden in below the seat cushion and shrink when upper/lower positions.
In addition, two connect supports 212 also is connected with two pilot bars 51 respectively, when two pilot bars 51 play guiding, also makes the operating steadily of entire mechanism.
