Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-6 This utility model provides a technical solution: an electric sofa that is easy to store, including a sofa base plate 1, side armrests 2, sofa backrest 3, movable plate 4, supporting top plate 5, sofa cushion 6, connecting block 7, backrest pillow 8, seat surface 9, leg support frame 10, foot support frame 11, L-shaped bracket one 12, pivot one 13, L-shaped bracket two 14, pivot two 15, push rod 16 and displacement slide rail 17;

[0033] Among them, the sofa base plate 1 is a supporting plate structure, and a side armrest 2 is symmetrically arranged on both sides of the sofa base plate 1. The sofa backrest 3 is arranged on the upper end of the sofa base plate 1, and the sofa backrest 3 and the sofa base plate 1 form an L-shaped sofa frame. The sofa base plate 1, the side armrest 2 and the sofa backrest 3 constitute the main supporting structure of the sofa.

[0034] A movable plate 4 is slidably connected to the upper end of the sofa base plate 1, and two strip openings are symmetrically opened at the bottom of the movable plate 4. A supporting top plate 5 is set on the upper end of the movable plate 4, and a sofa cushion 6 is installed on the upper end of the supporting top plate 5. One side of the sofa cushion 6 abuts against the side wall of the connecting block 7, and a backrest pillow 8 is set on the upper end of the connecting block 7. Three movable plates 4 are installed in sequence on the upper surface of the sofa base plate 1, and one end of the movable plate 4 is close to the sofa backrest 3. The two sides of the sofa backrest 3 abut against the surface of the side armrest 2, and a control switch is set on the surface of one side armrest 2. A slider of the displacement slide rail 17 is installed in the strip opening at the bottom of the movable plate 4, and the displacement slide rail 17 is installed on the upper end of the sofa base plate 1. The bottom end of the displacement slide rail 17 is flush with the bottom end of the movable plate 4. The connecting block 7 and the backrest pillow 8 are attached to the inclined surface of the sofa backrest 3, and the sofa backrest 3 is set as a triangular block structure.

[0035] Referring to the attached diagrams in the instruction manual Figure 1-6 As shown, the main frame structure of the sofa is formed by splicing and assembling the sofa base plate 1, side armrests 2, and sofa backrest 3. The sofa base plate 1 is installed by inserting both ends into the side armrests 2. The movable plate 4 installed on the upper end of the sofa base plate 1 is adjusted according to the data of the electric sofa. The support plate 5 installed on the upper end of the movable plate 4 provides support for the sofa cushion 6. Since the movable plate 4 extends to the sofa backrest 3 on one side, the movable plate 4 provides support for the connecting block 7. The backrest pillow 8 installed on the upper end of the connecting block 7 forms an L-shaped seating position. The thickness and hardness of the backrest pillow 8 can be modified according to the user's needs. The sofa floor area is adjusted by moving the movable plate 4 through the displacement rail 17 at the bottom, so that the sofa cushion 6 can be stored on one side of the sofa backrest 3, thereby realizing the storage function. The movable plate 4 drives the sofa cushion 6 and the connecting block 7 to slide outward. The backrest pillow 8 and the connecting block 7 are connected as one piece by Velcro or by sewing with outer fabric, so that the backrest pillow 8 can be tilted to facilitate the operation of the device.

[0036] The sofa cushion 6 has a seat surface 9 on its surface, and a leg support frame 10 is provided at the lower end of one side of the seat surface 9. A foot support frame 11 is provided at the lower end of the leg support frame 10. Two L-shaped brackets 12 are symmetrically and rotatably connected to the back of the foot support frame 11. A pivot 13 is provided between the two L-shaped brackets 12, and the pivot 13 passes through an L-shaped bracket 14. One end of the L-shaped bracket 14 is rotatably connected to the back of the leg support frame 10. There are two L-shaped brackets 14, and a pivot 15 is provided between the two L-shaped brackets 14. The top of the L-shaped bracket 14 is connected to the support top. The bottom end of the plate 5 is rotatably connected, and the surface of the rotating shaft 15 is fitted with a tube sleeve. The tube of the rotating shaft 15 is connected to the push rod 16. The L-shaped bracket 12 and the L-shaped bracket 14 are arranged vertically. The two ends of the rotating shaft 15 that passes through the L-shaped bracket 14 are provided with bearing sleeves. The connection between the tube of the rotating shaft 15 and the push rod 16 is set as a ball connector. The push rod 16 is installed in the groove inside the moving plate 4. The push rod 16 is connected to the control switch on the side wall of the side armrest 2 via a cable and electrical signal. The control switch on the side wall of the side armrest 2 is connected to the displacement slide rail 17 via a line.

[0037] Referring to the attached diagrams in the instruction manual Figure 1-6As shown, the seat surface 9 on the surface of the sofa cushion 6 is made of strip fabric, which covers the surfaces of the leg support frame 10 and the foot support frame 11. In use, the leg support frame 10 forms a stable installation structure through the L-shaped bracket 14 and the pivot 15. The upper end of the L-shaped bracket 14 rotates with the support top plate 5, and the pipe of the pivot 15 is pushed by the push rod 16. Due to the connection structure between the pipe of the pivot 15 and the ball part of the push rod 16, the pivot 15 pushes the L-shaped bracket 14 to rotate during the push of the push rod 16, causing the leg support frame 10 to tilt. At the same time, the pivot 13 passing through the L-shaped bracket 14 pushes the L-shaped bracket 12 to move outward and pushes the foot support frame 11 to tilt outward, forming a direction to support the user's legs. The displacement slide rail 17 installed in the strip opening of the moving plate 4 adjusts the seat depth according to the user's needs, so that the sofa cushion 6 above the moving plate 4 moves outward. The backrest pillow 8 moves along the connecting block 7 to adjust the tilt surface to cooperate with the overall seat movement of the sofa.

[0038] Working Principle: When using this conveniently foldable electric sofa, the main support structure of the sofa is formed by the sofa base 1, side armrests 2, and sofa back 3. A movable plate 4, placed on top of the sofa base 1, provides the main movement and support for the sofa. A displacement slide rail 17 at the bottom of the movable plate 4 pushes the entire electric sofa above the movable plate 4, adjusting the sliding position between the movable plate 4 and the sofa base 1 to reduce the sofa's placement space. This facilitates the movement and adjustment of the sofa above the movable plate 4, allowing the sofa cushions 6 to be folded back to one side of the sofa back 3, thus achieving the storage function. The upper part of the sofa cushion 6, the connecting block 7, and the backrest pillow 8 form the sofa seat and backrest. When using the leg support frame 10 and foot support frame 11, the push rod 16 pushes the rotating shaft 15, causing the L-shaped bracket 12 to rotate and push the rotating shaft 13 and L-shaped bracket 12 to move outward, so that the leg support frame 10 forms an inclined plane and pushes the foot support frame 11 to tilt outward to support the user's lower limbs. The control switch on the side wall of the side armrest 2 is connected to the displacement slide rail 17 and the push rod 16 through the circuit to control the moving plate 4 and the leg support frame 10, realizing the adjustment function of the electric sofa and increasing the overall practicality.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
