Universal angle controller for automobile seat

Abstract

The invention discloses a universal angle controller for an automobile seat and belongs to the technical field of automobile seat fittings. The universal angle controller comprises a fluted disc seat, a fluted disc, small toothed plates, a small toothed plate driving mechanism and a closed ring, and is characterized in that: a first shaft hole, a first positioning lug boss and a concave cavity are formed on the fluted disc seat; a toothed plate positioning lug boss, a supporting lug boss and a spring accommodating cavity are formed in the concave cavity; a second shaft hole, an accommodating cavity and a second positioning lug boss are formed on the fluted disc; an inner ring and an outer ring are formed outside the accommodating cavity; a limiting block is arranged on the inner ring; a gear ring is arranged on the outer ring; the small toothed plate driving mechanism comprises a cam plate, a central shaft and a spring; at least two small toothed plates in a fan shape are arranged; a toothed plate positioning hole, teeth, a tab groove, a bottom edge, a limiting lug boss and a contour lug boss are formed on each small toothed plate; and the closed ring is encapsulated at the periphery of the fluted disc seat and the fluted disc. The invention has the advantages that: the locking is reliable, and the gap is small; an idle gear is present, and the angle can be rapidly changed; and the device is high in strength, convenient to unlock, high in action flexibility, reliable in performance, small in volume, convenient to assemble, convenient to process and manufacture and wide in application range.

Description

technical field [0001] The invention belongs to the technical field of car seat accessories, and in particular relates to a universal car seat which is installed between the seat back and the seat and can properly adjust the angle between the seat back and the seat seat. Adjuster . 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. When t...

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

But also expose following problem in actual use: 1, owing to adopt three small tooth plates, three small tooth plates are the whole week even distribution, so can't be provided with no cogging on the ring gear, thereby there is no empty gear, The angle of the recliner cannot be changed quickly; 2. Since the small tooth plate is driven to move in a straight line through the rotation of the driving mechanism, and there are two contact surfaces under force when locked, the processing accuracy of the parts is particularly high, and the angle adjustment The clearance of the device is not well controlled
