Description

Cylinder unlocking mechanism

Technical Field

The utility model relates to the technical field of automobile seats, in particular to an air cylinder unlocking mechanism.

Background

The existing seat adjusting devices are various, and the existing seat adjusting devices are quite common in backrest unlocking, slide rail unlocking and turntable unlocking. The backrest unlocking mechanism mainly comprises a buckle, a stay wire, a pulling piece and a rotating pin. The two ends of the pull wire are respectively connected with the buckle hand and the pull piece, the rotating pin is connected with the pull piece, when the buckle hand is manually buckled, the pull wire enables the pull piece to drive the rotating pin to rotate, and the rotating pin drives the inner core piece of the angle adjuster connected with the rotating pin to unlock when rotating, so that the backrest can be unlocked. The slide rail unlocking mainly comprises a pressing plate, a rivet, a lock pin, a pressing plate rotating pin, a spring piece, a pull rod connecting plate and an unlocking pull rod. One end of the pressing plate is connected with the lock pin through a rivet, the middle of the pressing plate is connected with the elastic sheet through a pressing plate rotating pin, the pressing plate can rotate around the pressing plate rotating pin, the other end of the pressing plate is connected with the unlocking pull rod through the pull rod connecting plate, the elastic sheet is riveted with the upper sliding rail, and the whole mechanism can move along with the front-back adjustment of the upper sliding rail. And the spring plate pushes the pressing plate upwards in a natural state. When the unlocking pull rod is lifted upwards by hand, the pressing plate rotates around the pressing plate rotating pin, so that the lock pin moves downwards, and when the lock pin moves to a sliding tooth separated from the upper sliding rail and the lower sliding rail, the sliding rail is unlocked. Unlocking of the turntables requires separate unlocking by separate wrenches. The automobile seat adjusting mechanism needs to unlock the backrest (or the sliding rail) firstly, unlock the sliding rail (or the backrest) and unlock the turntable secondly, and is inconvenient to operate. Therefore, the adjusting device brings very inconvenient riding feeling to the passengers in the actual use process.

In patent CN202120922332.0, an electric unlocking device for a manual rotation mechanism of an automobile seat is disclosed, which comprises a seat and a manual rotation mechanism, wherein the seat is installed on the manual rotation mechanism, after the manual rotation mechanism is unlocked, the seat can be manually rotated on the manual rotation mechanism, the electric unlocking device is installed on the manual rotation mechanism and comprises an unlocking motor component and an unlocking cable component, and after the unlocking motor component is electrified, the unlocking cable component drives a lock component in the manual rotation mechanism to unlock, so that the manual rotation mechanism is unlocked; after the manual rotating mechanism is unlocked, the seat can rotate; if the seat rotates, the unlocking cable assembly is released after the unlocking motor assembly is powered off, and the lock assembly in the manual rotation mechanism returns to the locking state again but cannot scratch with the manual rotation mechanism. After the electric unlocking device is unlocked, the unlocking control switch is not required to be pressed all the time, the motor is powered off, the locked state does not exist, but the electric unlocking device still needs to be adjusted manually, so that the electric unlocking device is not convenient in some cases.
