[0024] Referring to Figures 1-7 A sofa with lifting function, comprising: cushion 1, one side of the cushion 1 is provided with back cushion 2, the bottom of the cushion 1 is provided with installation box 3 and lifting adjusting mechanism 4, the bottom of the installation box 3 is provided with universal wheel 6 and storage assembly, the storage assembly comprises: storage box 5, guide frame 502 and guide rail 503, the lifting adjusting mechanism 4 comprises: drive motor 407, bidirectional screw rod 403 and two support plates 401, the bottom of the support plate 401 is fixedly installed with support column 402 on both sides, the outer side of the bidirectional screw rod 403 is threadedly connected with sliding plate 404 on both ends, the front and rear sides of the sliding plate 404 are rotatably installed with connecting plate 405, the other end of the connecting plate 405 is hinged to the corresponding support plate 401.
[0025] In the embodiment, the installation box 3 is fixedly installed at the bottom of the cushion 1, the drive motor 407 is fixedly installed on the inner wall of one side of the installation box 3, the output end of the drive motor 407 is fixedly installed on one end of the bidirectional screw rod 403, the bidirectional screw rod 403 can be directly driven to rotate by starting the drive motor 407, the other end of the bidirectional screw rod 403 is rotatably installed on the inner wall of the other side of the installation box 3.
[0026] In the embodiment, a plurality of sliding rails 406 are fixedly installed on the top inner wall of the installation box 3, the sliding plate 404 is slidingly sleeved on the outer side of the corresponding sliding rail 406, and the horizontal movement of the sliding plate 404 is guided.
[0027] The top of the support plate 401 is fixedly installed with a vertical plate 408 which is slidingly installed in the mounting box 3 and plays a guiding role between the support plate 401 and the mounting box 3. The universal wheels 6 are arranged in four groups and are fixedly installed at the bottom of the mounting box 3 at four corners, thereby facilitating the movement of the mounting box 3.
[0028] In the embodiment, the top of the storage box 5 is open, the guide frames 502 and the guide rails 503 are arranged in two groups, the guide rails 503 are fixedly installed at the bottom of the mounting box 3, and the two guide frames 502 are fixedly installed at the two sides of the storage box 5 and slidingly sleeved outside the corresponding guide rails 503. The handle 501 is fixedly installed at the bottom of the storage box 5, thereby facilitating the movement of the storage box 5.
