[0025] 1. When the user needs to control the sofa to deform, the user can use the foot to push the contact plate to move into the control box. When the contact plate moves, the contact plate can synchronously push the push plate to rise through the L-shaped plate, and the push plate can synchronously push the limit plate to rise through the vertical plate. At this time, the limit plate is out of contact with the fixed plate, and the L-shaped plate pushes the rack to move, and the rack controls the gear tube to rotate through its own teeth. When the gear tube rotates, the gear tube controls the threaded column to rise through the thread on the inner wall. At this time, as the threaded column moves, the threaded column pushes the movable sleeve to engage with the gear;

[0026] 2. At this time, the motor is started, and the motor controls the movable sleeve to rotate through the gear. The movable sleeve pulls the sliding plate to move to the right through the pulling belt. At this time, the sliding plate pulls the pressure plate to descend through the connecting plate, and the pressure plate cooperates with the inclined surface of the triangular plate through the rotating wheel to push the control plate to move to the right. At this time, the control plate pulls the movable plate to move, and the movable plate pulls the backrest to rotate;

[0027] 3. As the backrest rotates, when the backrest rotates to the required angle, the foot is controlled to disengage from the contact plate. At this time, the contact plate cancels the pressure, and the vertical plate returns to its original position through the elastic force of the No. 3 spring, and the vertical plate drives the limiting plate to contact the fixed plate, at which time the movement of the fixed plate is restricted, thereby limiting and locking the deformation adjustment of the backrest, increasing the stability after deformation, and facilitating use.

[0028] When the user needs to control the sofa to deform, the contact plate can be pushed into the control box by using the feet, and the control plate can be driven to move. When the control plate moves, the control plate can control the backrest to rotate, thereby achieving the deformation adjustment effect. At the same time, by controlling the limiting plate to return to contact the fixed plate, the rotation angle of the backrest can be limited, which is convenient for users to use and ensures the comfort of users.

[0041] By means of the above-mentioned mechanism, by setting the support plate 6, the support plate 6 plays the effect of supporting the backrest 4 and limiting the rotation of the backrest 4. By setting the motor 2, by controlling the output shaft of the motor 2 to rotate, the output shaft of the motor 2 can synchronously drive the gear 3 to rotate. By setting the contact plate 12, by controlling the movement of the contact plate 12, the contact plate 12 can synchronously control the auxiliary mechanism and the control mechanism to work. By setting the control plate 7, by moving the control plate 7, the control plate 7 facilitates the rotation of the auxiliary backrest 4, thereby achieving the effect of adjusting the deformation.

[0042] As a preferred implementation scheme of this embodiment, the control mechanism includes a threaded column 15, a movable sleeve 16, a sliding plate 18, a connecting plate 19, a pressure plate 20 and a movable plate 8. The threaded column 15 is threadedly connected in the gear tube 14, and the outer wall of the threaded column 15 is slidably connected to the rear inner wall of the seat 1.

[0043] By setting a control mechanism, the backrest 4 can be automatically controlled to rotate through the control mechanism. By controlling the backrest 4 to rotate, the effect of controlling the sofa to deform can be achieved, which is convenient for adjustment according to the needs of the user.

[0044] In this embodiment, the rear side of the pressure plate 20 is rotatably connected to a rotating wheel, the left side of the control plate 7 is fixedly connected to a triangular plate 9, and the rotating wheel is in active contact with the inclined surface of the triangular plate 9, the left side of the control plate 7 is fixedly connected to a No. 1 spring 10, and one end of the No. 1 spring 10 is fixedly connected to the left side inner wall of the control box 5, and the bottom of the pressure plate 20 is fixedly connected to a No. 2 spring 21, and one end of the No. 2 spring 21 is fixedly connected to the bottom inner wall of the seat 1.

[0045] When the pressure plate 20 descends, the pressure plate 20 drives the rotating wheel to contact the inclined surface of the triangular plate 9. At this time, as the rotating wheel moves, the rotating wheel can push the triangular plate 9 to move through the inclined surface of the triangular plate 9, thereby synchronously driving the control plate 7 to move.

By setting a No. 2 spring 21, the elastic force of the No. 2 spring 21 can push the pressure plate 20 to return to its original position.

[0046] In this embodiment, the inner wall of the gear tube 14 is provided with threads, and the gear tube 14 is threadedly connected to the outer wall of the threaded column 15 through the threads.

[0047] When the gear tube 14 rotates, the gear tube 14 can control the threaded column 15 to move longitudinally through the threads on its inner wall.

[0048] In this embodiment, the inner wall of the movable sleeve 16 is provided with teeth, and the movable sleeve 16 is movably connected to the gear 3 . The outer wall of the movable sleeve 16 is wrapped with a pulling belt 17 , and one end of the pulling belt 17 is fixedly connected to the right side of the sliding plate 18 .

[0049] When the movable sleeve 16 is connected to the gear 3 , the gear 3 can rotate to control the movable sleeve 16 through the tooth pattern, so that the sliding plate 18 can be pulled by the pulling belt 17 to move synchronously.

[0050] In this embodiment, the auxiliary mechanism includes a rack 25, an L-shaped plate 13, a push plate 22, a vertical plate 23 and a limiting plate 26. The L-shaped plate 13 is fixedly connected to the left side of the contact plate 12, the rack 25 is fixedly connected to the left side of the L-shaped plate 13, and the rack 25 is meshed with the gear tube 14. The push plate 22 is rotatably connected to the front side of the L-shaped plate 13, the vertical plate 23 is slidably connected to the rear inner wall of the control box 5, and the front side of the vertical plate 23 is rotatably connected to the left side of the push plate 22, and the limiting plate 26 is fixedly connected to the rear side of the vertical plate 23.

[0051] By providing an auxiliary mechanism, the rotation of the backrest 4 can be restricted by the auxiliary mechanism, thereby facilitating positioning according to different needs of users and increasing comfort during use.

[0052] In this embodiment, a fixing plate 11 is fixedly connected to the front side of the control plate 7, a plurality of adapting holes are provided at the bottom of the limiting plate 26, and the fixing plate 11 is movably connected to the adapting holes.

[0053] By providing the fixing plate 11 and the adapting hole, when the fixing plate 11 is connected to the adapting hole, the rotation of the backrest 4 can be simultaneously restricted by restricting the movement of the fixing plate 11, thereby facilitating effective control of the backrest 4.

[0054] In this embodiment, a No. 3 spring 24 is fixedly connected to the top of the vertical plate 23 , and one end of the No. 3 spring 24 is fixedly connected to the top inner wall of the control box 5 .

[0055] By providing the No. 3 spring 24 , the vertical plate 23 can be pushed downward by the elastic force of the No. 3 spring 24 .

[0056] In this embodiment, a guide groove is provided on the front side of the backrest 4, and the rear side of the movable plate 8 extends into the guide groove and is slidably connected with the inner wall of the guide groove.

[0057] The guide groove is provided to assist the movable plate 8 in moving, so that the backrest 4 can be pulled to rotate.

[0058] In this embodiment, both the bottom of the seat 1 and the top of the control box 5 are provided with movable grooves, and the control panel 7 passes through the movable grooves and is slidably connected to the inner wall of the movable grooves.

[0059] By providing the movable groove, the control board 7 can be assisted in moving, while limiting the lateral movement of the control board 7.

[0060] Working principle: In actual operation, when the user needs to control the sofa to deform, the contact plate 12 can be pushed into the control box 5 by using the foot. When the contact plate 12 moves, the contact plate 12 pushes the L-shaped plate 13 to move. At this time, the L-shaped plate 13 can synchronously push the push plate 22 to rise. When the push plate 22 moves, the push plate 22 pushes the vertical plate 23 to rise. When the vertical plate 23 rises, the vertical plate 23 can synchronously push the limiting plate 26 to rise. At this time, with the movement of the limiting plate 26, the limiting plate 26 is out of contact with the fixed plate 11. At this time, with the movement of the L-shaped plate 13, the L-shaped plate 13 pushes the rack 25 to move. When the rack 25 moves, the rack 25 controls the gear tube 14 to rotate through its own tooth pattern.

[0061] When the gear tube 14 rotates, the gear tube 14 controls the threaded column 15 to rise through the thread on the inner wall. At this time, as the threaded column 15 moves, the threaded column 15 pushes the movable sleeve 16 to engage with the gear 3. At this time, the motor 2 is started, and the motor 2 controls the movable sleeve 16 to rotate through the gear 3. When the movable sleeve 16 rotates, the movable sleeve 16 controls the pulling belt 17 to move. When the pulling belt 17 moves, the pulling belt 17 pulls the sliding plate 18 to move to the right. At this time, as the sliding plate 18 moves, the sliding plate 18 pulls the pressure plate 20 to descend through the connecting plate 19.

[0062] When the pressing plate 20 descends, the pressing plate 20 cooperates with the inclined surface of the triangular plate 9 through the rotating wheel, and can push the control plate 7 to move to the right. At this time, as the control plate 7 moves, the control plate 7 pulls the movable plate 8 to move. At the same time, as the movable plate 8 moves, the movable plate 8 pulls the backrest 4 to rotate. At this time, as the backrest 4 rotates, when the backrest 4 rotates to a required angle, the contact plate 12 is disengaged by controlling the foot. At this time, the contact plate 12 cancels the pressure, and the vertical plate 23 returns to its original position through the elastic force of the No. 3 spring 24. As the vertical plate 23 returns to its original position, the vertical plate 23 drives the limiting plate 26 to contact the fixed plate 11, and the movement of the fixed plate 11 is restricted. The deformation adjustment of the backrest 4 is restricted and locked, thereby increasing the stability after deformation and facilitating use.

[0063] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
