[0030] The present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Combined with Figures 1 to 8 , this embodiment discloses a dual-purpose seat, including a base 1, a main body 2 and a flipping transmission structure, which can present two states of a seat and a temporary bed (chaise longue), serving two purposes with one object, and having better support performance and lying comfort compared with the existing conventional deformable seats.

[0032] Specifically, the base 1 is a rectangular support structure, and the base 1 is a rectangular support structure assembled by two first plate bodies 11 and two second plate bodies 12. The first plate body 11 and the second plate body 12 are locked and fixed by bolts. Both the first plate body 11 and the second plate body 12 are grid plate structures, and the grid structure is located inside. In this embodiment, the outer surfaces of the first plate body 11 and the second plate body 12 are smooth surfaces, which can improve the aesthetics. The inner surfaces of the first plate body 11 and the second plate body 12 are grid structures, which can improve the structural strength. Among them, the first plate body 11 and the second plate body 12 are integrally injection-molded, which is convenient for processing, has low material costs, uses structural design to ensure structural strength, and optimizes the use of materials in the production process to reduce manufacturing costs.

[0033] Furthermore, combined with Figure 4 and Figure 5, the two first plate bodies 11 are arranged oppositely, and the two second plate bodies 12 are arranged oppositely. An insertion socket 5 with a "U" - shaped structure is provided in the inner grid structure of the first plate body 11. The insertion socket 5 and the first plate body 11 are of an integrally formed structure. The insertion sockets 5 on the two first plate bodies 11 on both sides are aligned in pairs and grouped. A connecting beam 6 is arranged between the insertion sockets 5 in the same group. In this embodiment, the two connecting beams 6 are located at the inner bottom of the first plate body 11 and are distributed at intervals. The connecting beam 6 includes a beam body 61 adapted to the contour of the insertion socket 5. Both ends of the beam body 61 are inserted into the insertion slots to form a connection structure with the first plate bodies 11 on both sides, so that the connecting beam 6 forms a structure strengthening member between the two first plate bodies 11, and further makes the structure of the base 1 more stable and reliable.

[0034] Further, as shown in Figure 6 , a wrapping member 62 is arranged on the beam body 61. The wrapping member 62 is made of a rubber sleeve. Its function is to utilize its own certain elastic characteristics, so that when the base 1 is placed on the floor, the bottom of the beam body 61 can be closely attached to the floor. It can not only play an anti - slip role and improve the bearing stability of the base 1, but also play a noise reduction effect.

[0035] The top of the base 1 is movably connected with a main body 2. The main body 2 is composed of two seat cushions 21 and two backrest cushions 22, arranged in the order of seat cushion 21, two backrest cushions 22, and seat cushion 21, and the adjacent sides are connected by hinges 4, forming three flipping center structures. It should be noted that the flipping direction of the hinge 4 between the two backrest cushions 22 is opposite to the flipping directions of the other two hinges 4. A flipping transmission structure adapted to the flipping center structure is provided between the bottom of the seat cushion 21 and the top of the base 1. After the connecting sides of the two backrest cushions 22 move upward to the top, the backrest cushions 22 can flip into a vertical state and drive the outer seat cushion 21 to move towards the horizontal center side. A support structure is formed between the bottom of the seat cushion 21 and the top of the base 1, and Figure 1 as shown in Figure 2 the seat state; after the connecting sides of the two backrest cushions 22 move downward to the top, the backrest cushions 22 can flip into a horizontal state and drive the outer seat cushion 21 to move towards the horizontal outer side. A support structure is formed between the bottom of the backrest cushion 22 and the top of the base 1, that is,

[0036] the temporary bed (chaise longue) state shown in

[0037] To improve the structural stability and assembly stability, a base 3 is provided at the bottom of the seat cushion 21 and the back cushion 22. The base 3 is a grid plate structure. In this embodiment, the processing and material method of the base 3 is the same as that of the first plate body 11 or the second plate body 12, which makes the product production process more streamlined and efficient, and is also conducive to reducing production costs.

[0038] A cushion body is provided at the top of the seat cushion 21 and the back cushion 22. The outer layer of the cushion body is made of leather, with properties such as wear resistance, waterproofness, and firmness. The inside of the surface layer is filled with sponge, making the sitting or leaning more comfortable.

[0039] Further, as shown in Figure 4 the top of the second plate body 12 is lower than the top of the first plate body 11, and an activity gap 8 for the swing of the flipping transmission structure is formed between the top of the second plate body 12 and the main body 2.

[0040] A flipping transmission structure is arranged in the activity gap 8. Among them, as shown in Figure 7 and Figure 8 the flipping transmission structure is composed of a group of flipping frames 7 arranged in parallel at intervals. The flipping frame 7 includes an angle iron 71, a connecting rod 72, and a rib 73 hinged in sequence. The outer end of the angle iron 71 is fixedly connected to the bottom of the seat cushion 21 through bolts. The inner end of the angle iron 71 is a free end. The rib 73 is fixedly connected to the inner side wall of the base 1 through bolts. The two ends of the connecting rod 72 are respectively hinged to the angle iron 71 and the rib 73, forming a flipping linkage mechanism. It should be noted that the top of the free end of the inner side of the angle iron 71 can support the bottom of the back cushion 22 in the seat and temporary bed states. When extended into the temporary bed state, although the bottom of the seat cushion 21 is not directly supported by the base 1, the outer end of the angle iron 71 forms an extended support structure in this state, and is stably clamped by the upper and lower back cushions 22 and the base 1 in cooperation with the inner end, so that the bottom of the seat cushion 21 also has better support performance, thereby improving the structural strength and load-bearing stability.

[0041] In other embodiments, such as Figure 9As shown in the figure, in order to further improve the load-bearing stability, a buffer shaping structure is provided at the bottom of the package 62. Specifically, the buffer shaping structure includes a shaping sheet 621 located inside the bottom of the package 62. The shaping sheet 621 is made of steel plate. After installation, the shaping sheet 621 is attached to the bottom of the beam body 61, so that the overall structure of the bottom area of the package 62 will not be easily distorted under pressure. This enables the base 1 at the top to have better placement stability when used on some uneven floors. Further, a plurality of buffer cavities 622 are evenly arranged at the bottom of the package 62 below the shaping sheet 621. The buffer cavities 622 are composed of a plurality of longitudinally connected variable-diameter slot holes and form an opening structure on the bottom surface of the package 62. This enables the package 62 to have relatively flexible pressure deformation ability at the position of the buffer cavities 622. With the downward pressure of the product's own gravity, the bottom of the package 62 will adaptively deform. The bottom opening of the deformed buffer cavity 622 will play a suction effect similar to a suction cup, making the connection between the package 62 and the floor more stable and reliable, thereby improving the load-bearing stability of the product.
