AI Technical Summary
Existing car seats cannot be fully flattened, and the angles of the seat, backrest, and leg rest cannot be freely adjusted according to the user's habits, resulting in poor comfort when the user is resting.
It adopts a structure that combines an angle adjuster motor and a gear motor. The motor controls the angle adjuster disc and the limit block to achieve multi-angle adjustment of the seat, backrest and leg rest. Combined with the slide rail and horizontal motor, the seat can be moved horizontally. The cooperation of multiple motors and limit slots achieves self-locking to prevent collapse.
It enables precise angle adjustment of the seat, improving user comfort and flexibility, meeting the personalized needs of different users, and preventing the seat from collapsing during use.
