Abstract
An automobile seat angle adjuster comprises a gear cover (1), a gear bowl (2), a small gear sheet drive mechanism (4) and an edge covering ring (5). The automobile seat angle adjuster is characterized in that each small gear sheet (3) is of a two-level thickness stepped structure in the thickness direction, grooves (34) are formed due to the thickness level differences, and hanging lug holes (32) are formed in the thin walls of the small gear sheets (3); a cam plate (41) is further provided with protruding parts extending radially and hanging lugs (412) are arranged on the protruding parts; in a locking state, stop protrusions (413) of the cam plate abut against two bottom edges (33) of the small gear sheets; in the unlocking stroke, the hanging lugs (412) move along the hole walls in the hanging lug holes (32) to drive the small gear sheets to be displaced in the direction of a center shaft (42), and teeth of the small gear sheets are separated from a gear ring of the gear bowl. By the adoption of the automobile seat angle adjuster, the purposes of continuous uniformity, reliability and the like of motions of the small gear sheets are achieved, unlocking operation is convenient and stable, gaps of a product structure are small, the size is small, assembling operation is convenient, and production cost is low.
Description
Technical field
The invention belongs to auto use chair accessory technical field, be specifically related to a kind of for be arranged between the backrest of seat and seat, can suitably regulate backrest relative to the angle regulator for automobile chair of angle between seat.
Background technology
Angle regulator for automobile chair, for changing backrest swing angle.China Patent Publication No.: CN 101875321A, disclose the angle regulator for automobile chair of a kind of structure advanced person, comprise tooth lid, tooth bowl, little gear piece, little gear piece driver train, lobe plate and edged ring, by applying power on center shaft, thus act on lobe plate, and then act on one group of little gear piece by lobe plate, make little gear piece and tooth bowl depart from and realize the adjustment of back of seat.Still there is following weak point in the recliner design of said structure, one is the consistency of thickness of little gear piece and lobe plate, and be on same plane position, the mode that both relative positions can only be adopted to stagger is arranged at grade, little gear piece easily produces axial play and produces abnormal sound, two is in unblock stroke, blocked ear on lobe plate is before contacting blocked ear groove, little gear piece is in dissociated state, the continuity of instantaneous unblock and the process of unblock can not be guaranteed, affect structural compactness and the manipulation balance of product, three is in a latched condition, because forced contact face is insufficient and forced contact face is large not, and the forced position instability in blocked ear groove, these factors all can bring certain negative effect to the reliability of locking.
Summary of the invention
The object of the invention is to provide a kind of angle regulator for automobile chair, not only volume is little, structure is simple for it, easy to assembly, reliable lock, gap is little, convenient for unlocking, intensity are high, dexterity of action good, dependable performance, and be convenient to processing and fabricating, productive costs is low.
The object of the present invention is achieved like this, a kind of angle regulator for automobile chair, comprise tooth lid, tooth bowl, little gear piece driver train and edged ring, it is characterized in that: the thickness direction of little gear piece is thickness secondary hierarchic structure, the groove of lobe plate stroke is dodged in the differential formation of thickness, its thin-walled has the hangers hole with waist shaped hole shape approximation; Little gear piece driver train comprises lobe plate, center shaft and spring; It is convex that described lobe plate comprises gear, also has the radial outstanding position extended, this outstanding position is provided with column hangers; In a latched condition, the convex conflict of the gear of lobe plate is on two sections of bases of little gear piece; In unblock stroke, hangers againsts hole wall and moves in hangers hole, drives little gear piece to central axis direction displacement, makes the gear ring of the teeth of little gear piece and tooth bowl be in released state.
In said structure, the outstanding position extended due to the radial direction of lobe plate be against little gear piece thin-walled on move, meanwhile, column hangers moves in hangers hole, make little gear piece be in the restrained state of continuous print all the time in locking and unblock stroke, solve little gear piece and easily occur to loosen and manipulate the problems such as unstable, and the thickness of the little gear piece of the Thickness Ratio of lobe plate is thin, make product lighter, the compacter precision of structure.
Further scheme is, one end of described spring has the first spring for matching with lobe plate, lobe plate is provided with the jack for matching with the first spring, the other end of spring has the second spring for matching with tooth lid, tooth covers the spring jack offered for for the second spring inserting, first spring of above-mentioned spring is inserted in the jack on lobe plate, and the second spring is inserted in the jack that tooth covers.
In such scheme, further scheme is, in a latched condition, locking forced contact face also comprises: column hangers is conflicted on the hole wall in hangers hole.
For the design of spring, best scheme is: select arch spring, by tooth bowl by arch spring application, product structure can be made compacter, avoid part mutually to touch band and won't do impact.
The present invention is due to after employing said structure, tool has the following advantages: one, owing to matching with the hangers of three on lobe plate respectively in the hangers hole on three pieces of little gear pieces, therefore, when masterpiece is used for center shaft, drive three pieces of little gear pieces to slide by the rotation of lobe plate simultaneously, thus promptness and the conformability of all little gear piece action responses can be ensured, two, by action of the spring in lobe plate, and then drive all little gear pieces to reset by the rotation of lobe plate, the teeth of three pieces of little gear pieces realize well nibbling with the gear ring of tooth bowl respectively joins, three hangers of lobe plate are conflicted respectively on the hole wall in the hangers hole of three pieces of little gear pieces and form the first forced contact face a, and six of described lobe plate are kept off convex conflicts respectively on two sections of bases of three pieces of little gear pieces and form the second forced contact face b, therefore the technical program is more conducive to when locking ensureing engaging fastness between the teeth of little gear piece and the gear ring of tooth bowl, reliable lock, gap is little, three, convenient for unlocking, intensity is high, and dexterity of action is good, dependable performance, four, volume is little, and structure is simple, and easy to assembly, productive costs is low, five, applied widely, the connection between any seat can be realized.
