The specific embodiment
In conjunction with Fig. 1 to Fig. 8 the utility model is described in further detail.
A kind of vehicle seat position regulator structure-improved, comprise seat pipe 1, permanent seat 2, the seat cushion 3 that is located by connecting with permanent seat 2, be provided with sliding tube 5, these sliding tube 5 one ends are captiveed joint with permanent seat 2, and this sliding tube 5 is sheathed in the seat pipe 1, and the relative position between seat pipe 1 and sliding tube 5 are axial can be located adjusting, take the direction of riding as benchmark, the vertical dimension of sliding tube 5 rears one end is higher than the vertical dimension of sliding tube 5 the place aheads one end.Relatively moving between seat pipe 1 and the sliding tube 5 can be in the position of fore-and-aft direction adjusted seat cushion 3, and sliding tube 5 front and back vertical dimension differences are regulating seat cushion 3 height in vertical direction.
Be arranged with forward and backward screened housing 6,7 between sliding tube 5 and the seat pipe 1, and forward and backward screened housing 6,7 is positioned respectively described seat pipe 1 forward and backward two ends; The position of exposing seat pipe 1 and close front screened housing 6 one ends on the described sliding tube 5 is provided with limited screw 8.Seat cushion 3 is in course of adjustment, and when it moves forward distance when excessive, can utilize permanent seat 2 anti-skidding pipes 5 to break away from seat pipe 1; When seat cushion 3 when miles of relative movement is excessive backward, can utilize described limited screw 8 anti-skidding pipes 5 to break away from seat pipe 1.
The structure that seat pipe 1 and sliding tube 5 relative position between axially can be located adjusting is: described seat manage 1 the place ahead, one end dorsad seat cushion 3 one sides be provided with registration device, described registration device can be located the relative position between adjustment seat pipe 1 and the sliding tube 5.This registration device comprises the tightening screw that is actively located on the seat pipe 1 and can pushes against described sliding tube 5, and this tightening screw can adopt the mode of stepless time adjustment to regulate at sliding tube 5.Registration device also can be following structure: described registration device comprises and evenly is opened in the dorsad knock hole 51 of seat cushion 3 one sides of sliding tube 5 the place aheads one end, and fixedly is arranged on the seat pipe 1 and the end can reciprocating type activity snaps in and draws pin 9 in the described knock hole 51.Described knock hole 51 can be set to 4, and the distance between the described knock hole 51 can be made as 60mm, so can carry out as required the longitudinal separation of sectional type regulating seat cushion 3 and the high low degree of cushion 3.
The described pin 9 that draws comprises locating dowel pin 91, retracing spring 92, dowel bolt 93, pull handle neck 94, circlip 96 and the pull handle head 95 of captiveing joint with described locating dowel pin one end, and described pull handle head 95 is movably set on the described pull handle neck 94 and can endwisely slips along pull handle neck 94; The central axis of described dowel bolt 93 is provided with and can allows locating dowel pin 91 and be sheathed on the reciprocating through hole 931 of retracing spring 92 axial location on the described locating dowel pin 91; Described circlip 96 detachable cards are formed on described dowel bolt 93 away from pull handle head 95 1 ends, and described circlip 96 is positioned at described seat pipe 1.Circlip 96 is stuck in the seat pipe 1, can prevent from drawing pin 9 excessively to be pulled out.
The described retracing spring 92 that is sheathed on the locating dowel pin 91 can axially be located reciprocating structure and is in described through hole 931: described through hole 931 dwindles formation positioning step 932 near the aperture, position of pull handle head 95 1 ends, described retracing spring 92 1 ends are fixed on locating dowel pin 91 away from an end of pull handle head 95, and described retracing spring 92 other ends are fixed on described positioning step 932 places.Retracing spring 92 moves to positioning step 932 places, and the step 932 that is positioned stops and can not continue motion downwards that retracing spring 92 is compressed.
Described pull handle head 95 be movably set on the described pull handle neck 94 and can along pull handle neck 94 in axial sliding structure be: described pull handle neck 94 outer peripheral faces are provided with chute 941, be provided with convex tendon with chute 941 corresponding positions on described pull handle head 95 inner peripheral surfaces, described convex tendon can axially slide in chute 941.
Draw the principle of work of pin 9: the part that dowel bolt 93 is exposed at pull handle neck 94 outsides is provided with outside thread, and dowel bolt 93 is threaded fixing with seat pipe 1 by this outside thread, captives joint with pull handle neck 94 in dowel bolt 93 bottoms.
During use, draw pin 9 first towards a direction rotation 2 ~ 3 circles, then draw pin 9 downwards, wherein draw vertical distance that pin 9 rotates and drop-down apart from sum greater than drawing locating dowel pin 91 in the pin 9 to snap in length in the sliding tube 5.Dowel bolt 93 and pull handle neck 94 maintain static in pulling pull handle head 95; The retracing spring 92 that pull handle head 95 drive locating dowel pins 91 and upper end are connected on the locating dowel pin 91 moves downward, and in the motion process, retracing spring 92 compresses because of the barrier effect of positioning step 932, and locating dowel pin 91 withdraws from the knock hole 51 on the sliding tube 5 simultaneously; When seat cushion 3 moves to another sprocket bit, locating dowel pin 91 is not because being subject to the squeezing action of sliding tube 5 downsides, simultaneously because the rebound action of retracing spring 92, drive locating dowel pin 91 and thereon pull handle head 95 upward movements of being connected, locating dowel pin 91 is stuck in the new knock hole, so sliding tube 5 is fixed with a position of pipe 1.
The structure improved specific embodiment of vehicle seat position regulator:
Embodiment one:
In use, to draw first pin 9 towards a direction rotation 2 ~ 3 circles, then will draw pin 9 to be pulled to pin 9 downwards and break away from knock hole 51, then seat cushion 3 is mobile forward or backward, locating dowel pin 91 ends are resisted against on the sliding tube 5, decontrol this moment and draw pin 9, when seat cushion 3 continues to move to next knock hole 51 forward or backward, draw pin 9 automatic rebounding under the effect of retracing spring 92 to insert in this knock hole, seat cushion 3 and sliding tube 5 positions are fixed.Simultaneously because the height of sliding tube 5 rears one end is higher than the height of sliding tube 5 the place aheads one end, therefore when cushion 3 is mobile backward, cushion 3 also raises accordingly apart from the height on ground, moves forward Shi Zeqi apart from the simultaneously corresponding reduction of height on ground and work as cushion 3.
Embodiment two:
During use, tightening screw is unscrewed, the power that pushes against between seat pipe 1 and the sliding tube 5 is shed, this moment is mobile forward or backward with seat cushion 3, when adjusting to suitable position, tightening screw is screwed, by the power that pushes against between seat pipe 1 and the sliding tube 5 both are fixed.Simultaneously because the height of sliding tube 5 rears one end is higher than the height of sliding tube 5 the place aheads one end, therefore when cushion 3 is mobile backward, cushion 3 also raises accordingly apart from the height on ground, moves forward Shi Zeqi apart from the simultaneously corresponding reduction of height on ground and work as cushion 3.
