Universal stepless angle regulator

Abstract

The invention relates to a universal stepless angle regulator which belongs to automobile seat accessories. The universal stepless angle regulator comprises a fixed tooth plate, eccentric blocks, an eccentric retaining ring, internal teeth, a circlip, a swing tooth plate and a closed loop, wherein the fixed tooth plate is provided with a first axle hole, a first concave cavity, a first connection boss, a gear ring and an eccentric block seat; the eccentric blocks are a first eccentric block and a second eccentric block, and a pair of first and second retaining grooves, first and second eccentric holes, and first and second circlip grooves are arranged on the first and second eccentric blocks; the eccentric retaining ring is provided with a second axle hole, a pair of eccentric link stoppers, an abdicating groove and an eccentric axle seat; an annular gear is provided with a third axle hole and the internal teeth; a pair of circlip feet are arranged at the open end of the circlip; the swing tooth plate is provided with a fourth axle hole, a second concave cavity, a second connection boss and a tooth socket; and the closed loop is wrapped on the peripheries of the outer edges of the fixed tooth plate and the swing tooth plate. The invention has the advantages of simple structure, small clearance, small carry-over moment, no deflection angle, reliable locking, high strength, easy assembly, wide applicability and favorable universality, and can ensure reliable connection to a seat.

Description

technical field [0001] The invention relates to a recliner installed between the seat back and the seat cushion, which can properly adjust the angle of the seat back relative to the seat cushion, and is an improvement on the existing automobile seat recliner The structure improvement belongs to the technical field of car seat accessories. 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 betwee...

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 for 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, the consistency of the recliner gap is difficult to control, and the recliner cannot realize infinite displacement angle

However, the following problems have been exposed in the actual use process: 1. The machining accuracy of parts is required to be high; 2. The transmission torque is large; 3. The structure is more complicated
