A foot plate 1 for connecting the seat cushion frame is connected to one end of the rotating shaft 2; the other end of the rotating shaft 2 passes through the wire fixing bracket 3, the chassis side circular hole of the base plate 4 and the bracket circular hole of the bracket 6 and connects the coil spring installation box assembly 1 7 and the coil spring installation box assembly 2 8, and the tail end of the rotating shaft 2 passes through the rear end hole of the bracket 6 and is connected with a fastener. Preferably, the fastener is fastened with a nut 9. Ensure the stability and reliability of the rotating shaft.
[0025] The working principle of the above scheme is: when the seat needs to be flipped, the user only needs to apply a small force to start the flipping action. At this time, the coil springs in the coil spring mounting box assembly 1 and the coil spring mounting box assembly 2 start to work to provide assistance for the flipping action. The shaft 2 rotates smoothly with the help of the coil spring, driving the foot plate 1 to flip. When the seat is flipped into place, the elastic force of the coil spring keeps the seat stable to avoid shaking or shifting. Through the cooperation of the coil spring mounting box assembly 1 and the coil spring mounting box assembly 2, the two-way power-assisted flipping of the seat is achieved, reducing the difficulty of operation and labor intensity. The support and guiding function of the bracket and the concentric design ensure the stability and accuracy of the flipping process.
