The invention relates to the field of vehicle accessories, in particular to a locking and releasing reinforcing device and an electric seat. The locking and releasing reinforcing device comprises a shell, a gear transmission assembly, a worm gear and a worm are arranged in the shell, the bottom of the shell is detachably connected with a power-off brake, the power-off brake is connected with a transmission shaft, the side face of the worm is in meshed connection with the worm gear, and the bottom end of the worm is connected with the transmission shaft; the worm gear is connected with the gear transmission assembly, and the gear transmission assembly is connected with a spline shaft; the height of the backrest part of the seat is automatically adjusted by rotating a driving part, locking and releasing are achieved through the power-off brake, the response speed is high, the structure is simple and compact, the cost is low, large reverse damping torque can be borne when locking is conducted, at the moment, the friction torque of the power-off brake is amplified after being transmitted through the worm gear and the worm and the two-stage gear, and therefore the strength increasing function is achieved.
本发明涉及车辆配件领域,尤其是一种锁紧与释放加强装置及电动座椅,包括壳体,壳体内设有齿轮传动组件、蜗轮和蜗杆,壳体的底部可拆卸连接有失电制动器,失电制动器连接有传动轴,蜗杆的侧面与蜗轮啮合连接,且其底端与传动轴连接,蜗轮与齿轮传动组件连接,齿轮传动组件连接有花键轴,通过旋转驱动件自动调节座椅靠背部的高度,通过失电制动器实现锁紧与释放,响应速度快,结构简单紧凑,成本低,当锁紧时可承受较大的反向阻尼扭矩,此时失电制动器的摩擦扭矩通过蜗轮蜗杆和两级齿轮传动后放大,从而起到增加强度功能。
