Description
Technical field
The utility model relates to the vehicular spare parts field, particularly a kind of recliner that is used for automotive seat.
Background technology
Angle regulator for automobile chair is to be used to regulate chair back angle, thereby is that chaufeur or occupant obtain the comparatively comfortable parts of environment by bus.At present, the kind of angle regulator for automobile chair is a lot of both at home and abroad.The wherein built-in favor that circular angle regulator for automobile chair is little because of its volume, compact conformation receives vast automobile vendor.The built-in circular angle regulator for automobile chair of prior art; Comprise shell, have the circular tooth disk of internally toothed annulus, the disc seat that is provided with aperture, Locking Device and axle; Be configured for the inner chamber of ccontaining Locking Device between circular tooth disk and the disc seat; Locking Device comprises that cam, disc spring and an end are provided with the locking tooth plate with internally toothed annulus mating teeth tooth; The disc seat inside face is provided with and supplies the locking tooth plate chute of bearing fit within it, and the one or both ends of cam are arranged with the shifting block that matches with the locking tooth plate, and the other end of locking tooth plate is provided with the locking groove that matches with shifting block.But problem is that the center fit of the built-in disc spring of prior art is installed on the center shaft of angle regulator for automobile chair, and an end of disc spring is resisted against the projection that upper cam surface is provided with, and the other end of disc spring is embedded in the aperture of disc seat of angle regulator for automobile chair.But in actual use, because the locking disc spring plays reset response, projection is bigger painstakingly, deform easily in addition come off, the locking poor reliability.And mostly the quantity of the shifting block of the cam of prior art is 1 ~ 3, and the size of shifting block is bigger, and the tolerance clearance between shifting block and the locking groove is also bigger, and balance and stability are good inadequately.Cam shakes easily in the course of the work, and locking poor reliability, locking intensity are also good inadequately, thereby influences the normal operation of angle regulator for automobile chair.
Summary of the invention
The utility model technical matters to be solved is: the balance that cam is provided is better with stability, a kind of recliner that is used for automotive seat of locking good reliability.
The utility model addresses the above problem the technical scheme that is adopted: a kind of recliner that is used for automotive seat; Comprise circular tooth disk, disc seat and Locking Device with internally toothed annulus; Be configured for the inner chamber of ccontaining described Locking Device between described circular tooth disk and the disc seat; Described Locking Device comprises cam, disc spring and two locking tooth plates, and described locking tooth plate one end is provided with and described circular tooth disk internally toothed annulus mating teeth tooth, and described disc seat inside face is provided with and supplies the described locking tooth plate chute of bearing fit within it; Described cam is provided with four projections along circumference, is equipped with the locking groove that matches with described projection on the two locking tooth plates; The center of described cam is provided with and is used for the through hole that matches with square column; And the center of the lower surface of described cam is extended downwards and is used for the square platform that matches with disc spring; The square hole fit that described disc spring is provided with through the middle part is installed on the outer wall of described side's platform, and the free end of described disc spring is embedded in the aperture that described disc seat is provided with.
Compared with prior art, the advantage of the utility model is: this recliner cam that is used for automotive seat is provided with four projections along circumference, and locking tooth plate inboard is provided with the locking groove that matches with projection.Like this, cam remains four point locations in rotation process, makes that the stability of this recliner is better, and the working process cam is difficult for shaking, and locking intensity is higher.And the square hole fit that the disc spring of recliner is provided with through the middle part is installed on the outer wall of square platform of the lower surface of cam, so intensity is higher, be difficult for deforming and come off, good reliability, can guarantee the normal use of angle regulator for automobile chair.
