Angle regulator of car seat

Abstract

The invention discloses an angle regulator of a car seat and belongs to the technical field of car seat accessories. The angle regulator of the car seat comprises a fluted disc seat, a fluted disc, small toothed plates, a drive mechanism and a closed ring, wherein the fluted disc seat is provided with a first shaft hole, a first locating boss and a concave cavity; a toothed plate locating boss and a supporting boss are convexly arranged in the concave cavity; the fluted disc is provided with a second shaft hole, a holding cavity and a second locating boss; an inner ring and an outer ring are formed around the outer side of the holding cavity; the inner ring is convexly provided with a limiting block, and a tooth ring is formed on the outer ring; the drive mechanism comprises a cam block, a central shaft and a spring; at least two small toothed plates are put in the concave cavity of the fluted disc seat; and the closed ring is enveloped around the outer margin of the fluted disc seat and the outer margins of the fluted disc. The invention has the advantages as follows: the consistency of actions of the plurality of small toothed plates can be ensured; the lock is reliable; and the cam block can be prevented from shaking during rotation. The invention also has the characteristics of high intensity, no gap, enough free gear for rapidly changing the angle of the angle regulator, convenience for unlocking, good flexibility of actions, few parts, convenience for assembly and processing, low cost and wide range of application.

Description

technical field [0001] The invention belongs to the technical field of automobile seat accessories, and in particular relates to an automobile seat recliner which is installed between the seat back and the seat seat and can properly adjust the angle between the seat back and the seat seat . Background technique [0002] The function of the car seat recliner is as mentioned above. It is responsible for changing the forward and backward angle of the seat back. As such a device, it must be equipped on the car seat. At present, the recliner commonly used on the market for motor vehicle seats is a disc recliner, which mainly includes a fixed disc, a movable disc and a locking mechanism for maintaining the position of the backrest relative to the seat cushion. Dip attitude. The locking mechanism includes a rack ring on the movable disc and several pawls, each of which has a plurality of teeth. The ratchet can move radially between a locking position and an unlocking position. ...

AI Technical Summary

Problems solved by technology

This patent scheme discloses a "universal recliner", which has the advantages of high locking strength, small displacement angle, wide adjustment range, small axial clearance, good balance, simple structure, small volume, The advantage of easy installation, but the following problems are exposed in the actual use process: because the small tooth plate and the cam plate are both in the sliding groove of the fixed plate to perform linear motion respectively, and pass through the two sides of the ear retaining groove of the small tooth plate and the cam plate. The locking and disengagement of the recliner is realized by the action between the side retaining ears, so the processing accuracy of the parts is high, and the consistency of the recliner clearance is difficult to control

However, the following problems have been exposed in the actual use process: 1. Since the three small tooth plates are evenly distributed throughout the entire circumference, it is impossible to set no cogging on the ring gear; Gear limit structure, so there is no empty gear, and the angle of the recliner cannot be changed quickly; 2. Because the rotation of the driving mechanism drives the small tooth plate to move in a straight line, there is no clearance design, so the processing accuracy of the linear groove The requirements are particularly high, and the clearance of the recliner is not easy to control
