[0026] Reference Figure 1-3 ,

[0027] A sofa bed that saves storage space comprises: a base 1, a cushion 2, a first connecting rod 3, a second connecting rod 4 and a folding bed 5. The base 1 is a rectangular seat with an upper end that is concave downward to form a receiving cavity. The cushion 2 is placed on the upper end of the base 1. The lower end of the first connecting rod 3 is hinged to the inside of the base 1 through a pin, and the upper end of the first connecting rod 3 is hinged to the lower end of the cushion 2 through a pin. The lower end of the second connecting rod 4 is hinged to the inside of the base 1 through a pin, and the upper end of the second connecting rod 4 is hinged to the lower end of the cushion 2 through a pin. The folding bed 5 is connected to the inside of the base 1. The base 1, the cushion 2, the first connecting rod 3 and the second connecting rod 4 cooperate to form a double crank structure. When the upper ends of the first connecting rod 3 and the second connecting rod 4 are both rotated upward to raise the height, the cushion 2 can be lifted up to 20 cm at most, so that the cushion 2 can open the upper end of the base 1. At this time, the folding bed 5 can be unfolded from the receiving cavity and extend out of the base 1.

[0028] Specifically, when the seat cushion 2 opens the upper end of the base 1 and the folding bed 5 extends out of the accommodating cavity, the upper end of the seat cushion 2 can be rotated to form an obtuse angle relative to the folding bed 5. At this time, the user can sit on the folding bed 5 with his waist leaning on the seat cushion 2 for use.

[0029] Specifically, the folding bed 5 includes: a support pad 51, a spring 52 and a frame 53. The support pad 51 is an elastic mattress, the edge of the support pad 51 is hooked and fixed with one end of the spring 52, and the other end of the spring 52 is hooked and fixed with the inner circle of the frame 53. When the user lies on the support pad 51 or sits on the support pad 51, the spring 52 and the support pad 51 can cushion the user.

[0030] Specifically, the frame 53 includes: load-bearing rods 531. Multiple groups of load-bearing rods 531 are provided, and the multiple groups of load-bearing rods 531 are connected end to end to form a ring shape. The ends of adjacent load-bearing rods 531 are hinged to each other through hinges, and the support pad 51 is placed between the multiple groups of load-bearing rods 531. The ends of the springs 52 are fixed to the load-bearing rods 531. When the worker folds the folding bed 5, the load-bearing rods 531 are rotated around the hinges at the ends, so that the load-bearing rods 531 rotate around the hinges at the ends and stack on each other, thereby realizing the folding of the folding bed 5.

[0031] Specifically, the frame 53 further includes: a support leg 532, a first support rod 533 and a second support rod 534. The upper end of the support leg 532 is hinged to a group of load-bearing rods 531, one end of the first support rod 533 is hinged to the upper part of the support leg 532, the other end of the first support rod 533 is hinged to one end of the second support rod 534, and the other end of the second support rod 534 is hinged to another adjacent group of load-bearing rods 531. When the folding bed 5 is unfolded, the support leg 532 is perpendicular to the ground and the load-bearing rod 531 is parallel to the ground. The first support rod 533 and the second support rod 534 are located on the same straight line and support the support leg 532 obliquely relative to the ground. When the user folds the folding bed 5, a group of load-bearing rods 531 rotate upward and toward an adjacent group of load-bearing rods 531, thereby driving the support legs 532 to rotate, and the support legs 532 drive the first support rod 533 and the second support rod 534 to rotate closer to each other, and finally the first support rod 533 and the second support rod 534 rotate to form an acute angle with each other, and the support legs 532 rotate to fit with the connected load-bearing rods 531.

[0032] Specifically, the folding bed 5 further includes: a third connecting rod 54 and a fourth connecting rod 55. One end of the third connecting rod 54 is hinged to one end of the frame 53 close to the base 1 through a hinge, and the other end of the third connecting rod 54 is hinged to the base 1 through a hinge. One end of the fourth connecting rod 55 is hinged to the frame 53 through a hinge, and the other end of the fourth connecting rod 55 is hinged to the base 1 through a hinge. The base 1, the frame 53, the third connecting rod 54 and the fourth connecting rod 55 cooperate to form a double crank structure, so that the frame 53 extends upward from the receiving cavity and retracts downward into the receiving cavity. Thus, the user can store the folding bed 5 as a whole in the receiving space of the base 1 to reduce the overall footprint of the sofa bed.
