Embodiment 1
[0044] An electric sofa support suitable for lifting the self-locking space of a seat frame, comprising a lifting frame 1; the lifting frame 1 is driven by a linear motor to perform lifting motion;
[0045]The seat frame support 6 moves back and forth relative to the lifting frame 1; the seat frame support 6 is driven by a linear motor, and the linear motor drives the seat frame support 6 to move forward and backward on the lifting frame 1 through a drive frame. The back and forth movement of the support member 6 is an existing technology, which has been introduced in the patent documents previously applied by our company;
[0046] Rear rotating rod 2, its upper end is rotationally connected with seat frame support 6, and a guide groove is opened at the lower end; rear transmission rod 3, described rear transmission rod 3 forms a rotation connection with lifting frame 1 through first rivet 51, and the rear transmission rod 3. The upper end forms a rotational connection with th...
Embodiment 2
[0057] An electric sofa support includes a standing position, an initial position, a TV position, and a leisure position; the four positions correspond to the four postures of the sofa support during use, namely, the standing position, the initial position, and the TV position and casual posture;
[0058] The working method of the electric sofa support uses a linear motor to drive the drive frame to turn over, and then drives the seat frame support frame to move back and forth. pose to the final resting pose;
[0059] When the seat frame support 6 moves to the station-assisting station, the initial station, and the TV station, the seat frame support 6 is lifted and locked. By expanding the self-locking space of the electric sofa support, the sofa support can be realized in more stations. The lifting and self-locking of the seat frame improves the safety of the sofa support.
