[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0024] By providing a folding sofa bed structure in the embodiments of the present application, the problems that the sofa cannot meet multiple uses, resulting in poor practicality, and that before the backrest 201 is lowered, it is necessary to manually adjust the position of the sofa to avoid contact and collision between the backrest 201 and the wall, and then lower the backrest 201 of the sofa, making the folding adjustment process of the sofa cumbersome are solved. When the support base 3 is driven by the electric telescopic rod 4 to move, the support base 3 contacts and presses against the wall at this time, pushing the base 1 away, driving the backrest 201 to move, facilitating the rotation of the backrest 201, without the need for manual adjustment, making the adjustment of the backrest 201 simple. At this time, the movement of the support base 3 causes the rotating rod 5 to rotate. At this time, the rotation of the rotating rod 5 pulls the backrest 201 to move, facilitating the adjustment of the backrest 201 to an appropriate angle, meeting multiple uses, being able to sit, lean, and lie down, enabling both work and leisure to be shared, and improving the practicality of the sofa.

[0025] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the specification drawings and specific embodiments.

[0026] The embodiments of the present utility model disclose a folding sofa bed structure.

[0027] According to the attached Figures 1-4 As shown, it includes a base 1, a seat cushion 2 is fixedly installed on the base 1, a backrest 201 is rotatably connected to the seat cushion 2, and between the backrest 201 and the base 1 is provided with:

[0028] An adjustment unit, the adjustment unit includes a support base 3 and an electric telescopic rod 4. The electric telescopic rod 4 is installed inside the base 1, and the output end of the electric telescopic rod 4 is fixedly connected to the support base 3. The support base 3 is connected to the base 1 through the electric telescopic rod 4. Under the action of the adjustment unit, the distance between the support base 3 and the base 1 is adjusted. By moving the support base 3 to the outermost edge, at this time, the upper part of the support base 3 contacts the backrest 201, supporting the backrest 201, making the backrest 201 and the seat cushion 2 more stable during use;

[0029] Rotating unit, the rotating unit includes a rotating rod 5, one end of the rotating rod 5 is rotatably connected to the support seat 3, and the other end of the rotating rod 5 is rotatably connected to the backrest 201. Under the action of the rotating unit, the support seat 3 moves to drive the rotating rod 5 and the backrest 201 to rotate. When the support seat 3 is driven by the electric telescopic rod 4 to move, at this time, the support seat 3 contacts and presses against the wall, pushing the base 1 away, driving the backrest 201 to move, facilitating the rotation of the backrest 201. No manual adjustment is required, making the adjustment of the backrest 201 simple. At this time, the movement of the support seat 3 causes the rotating rod 5 to rotate. At this time, the rotation of the rotating rod 5 pulls the fixed seat 501 on the backrest 201 to move, so that the backrest 201 rotates on the seat cushion 2 through the rotating seat 202, facilitating the adjustment of the backrest 201 to an appropriate angle, meeting various uses, being able to sit, lean, and lie down, enabling both work and leisure to be shared, and improving the practicality of the sofa.

[0030] A drawer 101 is slidably connected to the inner wall of the base 1. The drawer 101 is used for storing sundries, facilitating space saving in a user-friendly manner.

[0031] An installation groove 102 is provided on the base 1. The installation groove 102 is used for installing the electric telescopic rod 4, and at the same time, the installation groove 102 is used for storing the rotating rod 5 and the fixed seat 501, facilitating the backrest 201 to fit with the base 1 and the support seat 3.

[0032] A rotating seat 202 is fixedly connected to the inner wall of the backrest 201. The rotating seat 202 is rotatably connected to the outer wall of the seat cushion 2. By the rotating seat 202, the rotation path of the backrest 201 is limited, making the rotation path of the backrest 201 stable and facilitating the stability of adjustment.

[0033] A fixed seat 501 is fixedly connected to the outer wall of the backrest 201. The fixed seat 501 is rotatably connected to the rotating rod 5. Under the action of the fixed seat 501, the rotating rod 5 is rotatably connected to the backrest 201; when the support seat 3 is driven by the electric telescopic rod 4 to move, at this time, the movement of the support seat 3 causes the rotating rod 5 to rotate. At this time, the rotation of the rotating rod 5 pulls the fixed seat 501 on the backrest 201 to move, so that the backrest 201 rotates on the seat cushion 2 through the rotating seat 202, facilitating the adjustment of the backrest 201 to an appropriate angle, meeting various uses, being able to sit, lean, and lie down, enabling both work and leisure to be shared; when the support seat 3 moves to the outermost edge, at this time, the upper part of the support seat 3 contacts the backrest 201, supporting the backrest 201, making the backrest 201 and the seat cushion 2 more stable during use.

[0034] A socket 6 is slidably connected to the inner walls of the fixed seat 501 and one of the rotating rods 5.

[0035] A pull block 601 is fixedly connected to the outer wall of the socket 6. By inserting the socket 6 into the rotating rod 5, the rotation angle of the rotating rod 5 is limited, which facilitates the support of the rotating rod 5 for the backrest 201. By pulling out the socket 6 through the pull block 601, the socket 6 is separated from the rotating rod 5. At this time, the movement of the support base 3 drives the rotating rod 5 to rotate, so as to adjust the rotation of the backrest 201.

[0036] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only used to illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and all these changes and improvements fall within the scope of the present invention claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
