[0015] like Figure 1-9As shown, a double-cylinder controlled leisure seat frame platform with a rotating arm swing-out mechanism comprises: a bottom frame 1, which comprises a bottom beam 11 and connecting arms 12 fixedly connected to both sides of the bottom beam 11; a seat frame 2, the front end of which is rotatably connected to a leg frame 3 that can be flipped relative to the seat frame 2; a backrest frame 4, which is rotatably connected to the rear end of the seat frame 2, and a first driving cylinder 41 is connected between the backrest frame 4 and the seat frame 2 to drive it to lie down or stand up relative to the seat frame 2, and armrests 5 are fixedly connected to both sides of the backrest frame 4; a swing-out mechanism 6, which comprises a support swing arm 61 connected to the connecting arm 12, and a leg frame 3 connected to the backrest frame 2; a backrest frame 4, which is rotatably connected to the rear end of the seat frame 2, and a first driving cylinder 41 is connected between the backrest frame 4 and the seat frame 2 to drive the backrest frame 4 to lie down or stand up relative to the seat frame 2; armrests 5 are fixedly connected to both sides of the backrest frame 4; a swing-out mechanism 6, which comprises a support swing arm 61 connected to the connecting arm 12, and a leg frame 3 connected to the backrest frame 2; a backrest frame 4, which is rotatably connected to the rear end of the seat frame 2, and a first driving cylinder 41 is connected to the backrest frame 4 to drive the backrest frame 4 to lie down or stand up relative to the seat frame 2; armrests 5 are fixedly connected to both sides of the backrest frame 4; a swing-out mechanism 6, which comprises a support swing arm 61 connected to the connecting arm 12, and a leg frame 3 connected to the backrest frame 2; a leg frame 3 connected to the backrest frame 2; a leg frame 3 connected to the backrest frame 2; a leg frame 3 connected A front swing arm 62 and a rear swing arm 63 between the connecting arm 12 and the seat frame 2, an intermediate swing arm 64 connected between the supporting swing arm 61 and the seat frame 2, and a connecting swing arm 65 connected between the supporting swing arm 61 and the leg frame 3, a second driving cylinder 66 is connected between the seat frame 2 and the supporting swing arm 61, and the second driving cylinder 66 can drive the supporting swing arm 61, the front swing arm 62, the rear swing arm 63, the intermediate swing arm 64 and the connecting swing arm 65 to swing, so as to realize the front and rear, up and down swinging of the seat frame 2 and the flipping, opening and closing of the leg frame 3 relative to the seat frame 2; the front swing arm 62 and the rear swing arm 64 are connected between the seat frame 2 and the supporting swing arm 61. There is a height difference between the swing arms 63, and the position of the middle swing arm 64 is between the front swing arm 62 and the rear swing arm 63; the connecting swing arm 65 and the middle swing arm 64 share a fulcrum; a fixed bracket 7 is arranged below the leg frame 3, and a long groove 71 is arranged on the fixed bracket 7, and a roller 72 is slidably arranged in the long groove 71, and the roller 72 is connected to a first connecting rod 73, and the first connecting rod 73 is connected to a second connecting rod 74, and the second connecting rod 74 is connected to a third connecting rod 75, and the other end of the third connecting rod 75 is fixed to the seat frame 2. When the second driving cylinder 66 drives the connecting swing arm 65 to swing, the first connecting rod 73 is connected to the second connecting rod 74, and the second connecting rod 74 is connected to the third connecting rod 75. The connecting rod 73 and the second connecting rod 74 move and the roller 72 slides in the long groove 71 to limit the position of the leg frame 3 being flipped open and folded relative to the seat frame 2; the leg frame 3 includes a fixed frame 31, a slide rail 32 arranged on the fixed frame 31, a movable frame 33 that slides with the slide rail 32 and can move relative to the fixed frame 31, and a telescopic cylinder 34 connected between the fixed frame 31 and the movable frame 33; a support frame 8 is provided on the rear side of the backrest frame 4, and the armrest 5 is fixedly connected to the backrest frame 4 through the support frame 8, and the first drive cylinder 41 is connected between the support frame 8 and the seat frame 2.

[0016] By adopting the above technical solution, in the present invention, the armrest 5 and the backrest frame 4 are fixedly connected so that the armrest 5 and the backrest frame 4 become an integrated structure, thereby improving the integrity of the product and making the product more beautiful. The armrest 5 can always maintain a certain angle with the backrest frame 4 when the backrest frame 4 rotates and adjusts relative to the seat frame 2, and the user's comfort is better. Specifically, during installation, the armrest 5 and the support frame 8 can be fixed or integrated, and then the armrest 5 is fixed to the backrest frame 4 through fasteners to form an integrated main frame. Then the main frame is fixed to the rotating shaft of the seat frame 2 through fasteners, and the rotating shaft can rotate in the shaft sleeve of the seat frame 2, so that a structure in which the main frame rotates relative to the seat frame 2 is formed. Then, a first driving cylinder 41 is connected between the back frame 4 and the seat frame 2. The first driving cylinder 41 can be an electric cylinder to form a driving mechanism, so that the standing and lying down of the main frame relative to the seat frame 2 can be adjusted, that is, the armrest 5 and the back frame 4 are linked together to realize the flipping function, avoiding the independent separation of the armrest 5 and the back frame 4, which leads to the problem of split product design.

[0017] Furthermore, by providing a swing-out mechanism 6, specifically, the swing-out mechanism 6 includes a support swing arm 61 connected to the connecting arm 12, a front swing arm 62 and a rear swing arm 63 connected between the connecting arm 12 and the seat frame 2, an intermediate swing arm 64 connected between the support swing arm 61 and the seat frame 2, and a connecting swing arm 65 connected between the support swing arm 61 and the leg frame 3, a second driving cylinder 66 is connected between the seat frame 2 and the support swing arm 61, there is a height difference between the front swing arm 62 and the rear swing arm 63, the position of the intermediate swing arm 64 is between the front swing arm 62 and the rear swing arm 63, and the connecting swing arm 65 and the intermediate swing arm 64 share a fulcrum. In this way, when the second driving cylinder 66 is actuated, the seat frame 2 can swing up and down and forward and backward relative to the bottom frame 1 (the bottom frame 1 is fixed on the ground). In addition, the provision of the connecting swing arm 65 can realize the flipping, opening and folding of the leg frame 3.

[0018] Specifically, the leg frame 3 includes a fixed frame 31 and a movable frame 33, a connecting swing arm 65 connected to the fixed frame 31, and a fixed bracket 7 arranged below the leg frame 3, as well as a first connecting rod 73, a second connecting rod 74 and a third connecting rod 75, which can provide more stable support for the movement of the leg frame 3 when the connecting swing arm 65 moves, and can limit the flipping angle of the leg frame 3, that is, when the roller 72 slides to the two ends of the long groove 71, it is the upper and lower limits of the flipping angle of the leg frame 3. Among them, the specific length setting of the long groove 71 should match the accommodating space for accommodating the leg frame 3 below the seat frame 2, so as not to interfere with other components when the leg frame 3 flips.

[0019] In addition, a slide rail 32 is provided on the fixed frame 31, and a telescopic cylinder 34 is provided between the fixed frame 31 and the movable frame 33, so that the movable frame 33 can be extended or retracted relative to the fixed frame 31. Specifically, when the leg frame 3 is flipped open relative to the seat frame 2, the movable frame 33 can be operated to extend, so that the leg frame 3 can provide a more comfortable use experience.

[0020] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
