The invention relates to an electric backrest folding mechanism. The electric backrest folding mechanism comprises an angle adjuster lower connecting plate, an angle adjuster upper connecting plate and an angle adjuster, wherein the angle adjuster lower connecting plate is connected with the angle adjuster upper connecting plate through the angle adjuster; the gearwheel is fixedly mounted on the angle adjuster lower connecting plate; the unlocking handle is rotatably mounted on the angle adjuster lower connecting plate; an unlocking cam driven by a motor is matched with an unlocking handle toachieve unlocking and locking of the recliner, a small gear meshed with a large gear is rotatably installed on the unlocking cam, and the small gear is intermittently driven by the unlocking cam to achieve angle adjustment of an upper connecting plate of the recliner relative to a lower connecting plate of the recliner. According to the electric backrest folding mechanism, the unlocking cam is matched with the unlocking handle to achieve unlocking and locking of the recliner, the unlocking cam intermittently drives the small gear to achieve angle adjustment of the recliner upper connecting plate relative to the recliner lower connecting plate, and the electric backrest turnover mechanism is convenient to arrange, small in occupied space and free of high requirements for the installation environment.
本发明涉及一种电动靠背翻折机构,其包括调角器下连接板、调角器上连接板和调角器,其中,调角器下连接板和调角器上连接板通过调角器连接,大齿轮固定安装在调角器下连接板上,解锁手柄可转动地安装在调角器下连接板上,通过电机驱动的解锁凸轮与解锁手柄配合来实现调角器的解锁和锁止,与大齿轮啮合的小齿轮可转动地安装在解锁凸轮上并通过解锁凸轮间歇驱动小齿轮来实现调角器上连接板相对于调角器下连接板的角度调节。根据本发明的电动靠背翻折机构,通过解锁凸轮与解锁手柄配合来实现调角器的解锁和锁止,通过解锁凸轮间歇驱动小齿轮来实现调角器上连接板相对于调角器下连接板的角度调节,方便布置,占用空间小,对安装环境并没有高要求。
