Description
Technical field
The utility model relates to a kind of circular three toothed plate type angle regulator for automobile chair.Belong to field of automobile.
Background technology
The kind silver of angle regulator for automobile chair is many both at home and abroad at present.See from its operating mode to mainly contain hand wheel type and handle type, closely also occurred electrodynamic type again.Various recliner all have its advantage, and its shortcoming is also arranged.The locking that has is reliable but cost is big, though the low cost of manufacture locking reliability that has is also poor, is prone to slip teeth and collapses tooth.The electrically operated cost of complex structure especially is big.
Summary of the invention
The purpose of this utility model is to provide a kind of and regulates flexibly, reliable, the economical and practical circle three toothed plate type angle regulator for automobile chair of locking.
The technical solution of the utility model is: a kind of circular three toothed plate type angle regulator for automobile chair, it includes symmetrical left recliner and right recliner, has gangbar to link between two recliner.The center shaft middle part of its one-sided recliner is connected with camshaft, is set with lower plate, center part, upper plate, disc spring and back-up ring on center shaft and the camshaft successively in proper order.Disc spring one end and center shaft socket-connect, and the flap of the other end and lower plate colludes and is connected.The structure of center part is as follows: be set with circular tooth disk, driver chuck, cam, lock tooth torsion spring and disk on center shaft and the camshaft successively in proper order.Circular hole can rotate around camshaft in the middle of circular tooth disk, the disk, and driver chuck, cam, lock tooth torsion spring all are connected with camshaft square in shape structure and all can not rotate around camshaft.Circular tooth disk has the flanging to the center, and the flanging inner ring is provided with internal tooth.Driver chuck, cam, lock tooth torsion spring and little tooth plate all are contained in the flanging of circular tooth disk formation.Have three curve slotted eyes on the driver chuck, also have three small sircle holes on the driver chuck, cam is provided with three roundlet projections, on the driver chuck on three small sircle holes and the cam three roundlet projection flush fits install.The lock tooth torsion spring one end borehole jack that is square is contained on the camshaft square column, and its bent-up end is sleeved in the disk mounting hole after the other end bending.Disk is provided with three chutes, and three little tooth plates are contained in three chutes respectively and can slide in chute.Little tooth plate outer ring end is provided with external tooth, little tooth plate when move the outer ring outer ring end external tooth can and the internal gearing of circular tooth disk.Little tooth plate inner ring end is provided with the protruding locking face of little tooth plate, and the cam outer ring is provided with cam projecting surface and cam recessed face, when the protruding locking face of little tooth plate and cam projecting surface join the internal tooth external tooth is meshed together tightly.When the protruding locking face of little tooth plate and cam recessed face joined, the internal tooth external tooth just was in the state that disengages.Each little tooth plate is provided with a boss platform on driver chuck one side face, this boss platform cooperates in the curve slotted eye that is installed on the driver chuck and can slide in the curve slotted eye.The boss platform of little tooth plate moves in the curve slotted eye, forms the lock tooth when little tooth plate internal tooth external tooth when move the outer ring just is in engagement, otherwise forms release when little tooth plate internal tooth external tooth when inner ring moves just is in separating contacting state.The involucrum outer ring is sleeved on disk and the circular tooth disk.Upper plate and disk weld together, upper plate also with the back of seat Joint.Lower plate and circular tooth disk weld together, lower plate also with seat support frame Joint.Handle is welded on the center shaft of left recliner or right recliner, and a handle torsion spring is arranged between handle and the lower plate.The center shaft of gangbar one end and left recliner is affixed, and the center shaft of the gangbar other end and right recliner is affixed.
Principle of work of the present utility model is: when no external force acted on handle, because the effect of lock tooth torsion spring makes outer, the internal tooth tight engagement of little tooth plate and circular tooth disk be lockup state together, this moment, motor vehicle seat back was in a relative angle running condition.When needs are regulated backrest angle, as long as upwards mention handle, when rotating, handle drives dial and synchronous rotation of cam while by center shaft, camshaft, when dial rotates its curve slotted eye rotate and drive little tooth plate the boss platform in the curve slotted eye, move little tooth plate moved to inner ring, this moment, the protruding locking face of little tooth plate inner ring end moved to the recessed face place of cam outer ring simultaneously, and just to be in separating contacting state be released state for internal tooth, external tooth like this.The occupant only needs to promote backrest with back strength just can make backrest rotate backward.Remove pressure to backrest as occupant's back, this moment, disc spring moment just can make backrest rotate forward.Release handle when backrest rotates the arrival desired location, the moment of lock tooth torsion spring will drive dial and cam rotates simultaneously synchronously, drives little tooth plate simultaneously to moving away from center position, at this moment inside and outside tooth engaging lock tooth.Motor vehicle seat back just is in another relative angle running condition like this.During inside and outside tooth engaging lock tooth, the protruding locking face of little tooth plate inner ring end moves to the projecting surface place of cam outer ring simultaneously, and the projecting surface of cam outer ring tightly withstands the protruding locking face of little tooth plate inner ring end, and this structure does not make the lock tooth reliably, can slip teeth not take off tooth.Can drive the opposite side recliner by gangbar during the action of band handle one side recliner and do same action, this about two recliner structures make this recliner performance more superior reliable.
The utility model has the advantages that provides a kind of regulate flexible, reliable, the economical and practical circle three toothed plate type angle regulator for automobile chair of locking.
