The seat adopts a left-right separated design, divided into a left seat and a right seat. The width ratio of the left seat is 60%, and the right seat accounts for 40%. The backrest angles of the left and right seats can be electrically adjusted by the motor 6 to adjust the angle requirements of the occupants for the seat backrest, improving the seating comfort of the occupants. The left seat frame 1, the right seat frame 3, and the column 5 are all welded in a double rectangular tube manner to improve the rigidity of the seat. The backrest can be flipped forward to the horizontal state with one key, improving the operating comfort. The left seat frame 1, the backrest steel plate 2, the first base 9, and the seat pan frame 10 are articulated with the corresponding pull rods through the connecting rod 12 to form a four-bar linkage structure. The left seat frame 1 and the right seat frame 3 are connected to the first base 9 through the motor 6 and the electric hinge 8 to realize the adjustment of the backrest angle. When the left seat frame 1 and the right seat frame 3 rotate, they simultaneously drive the seat pan frame 10 and the connecting rod 12 to rotate, realizing the sinking of the seat pan frame 10. When the left seat frame 1 and the right seat frame 3 rotate to the horizontal state, there is just enough space for the seat cushion, the backrest foam, and the leather cover between them. After folding, the storage space is small, and the seat pan frame 10 is a welded integral stamping steel plate, which improves the storage capacity when the seat pan frame 10 is stored in the horizontal state.
