Description

Full-automatic sofa spring bed

Technical Field

The invention relates to the field of furniture.

Background

The invention does not provide the full-automatic sofa Simmons bed in the furniture industry, only a simple sofa bed is full-automatic, a simple manual push-pull combined sofa bed is adopted in the industry, both the sofa bed and the Simmons bed are relatively simple, no matter the sofa bed or the Simmons bed has no soft and comfortable feeling, the use is extremely inconvenient, the full automation of conversion from the sofa bed to the Simmons bed is realized, the use is extremely simple and convenient for a user, meanwhile, the sofa Simmons bed and the Simmons bed are independently compared with the same type of the sofa bed and the Simmons bed, and the soft and comfortable feeling of the sofa Simmons bed is completely realized.

Disclosure of Invention

The invention firstly solves the requirement of extremely simple use, and simultaneously ensures that the backrest plate 1 and the seat plate 2 are in moderate softness, so that the sofa or the Simmons bed has excellent comfortable experience when being used as a main body of the sofa or the Simmons bed. The invention adopts the most basic mechanical transmission mode, so that the backrest plate 1 and the seat plate 2 extend forwards at the same time, the sofa bed is formed when the backrest plate 1 and the seat plate 2 are unfolded, and the sofa is formed when the backrest plate 1 and the seat plate 2 are folded. To achieve the desired effect of the sofa and Simmons bed, the back board 1 and seat board 2 of the present invention are designed to be thick enough to meet this requirement.

Drawings

Fig. 1 is a schematic perspective view of the full-automatic sofa Simmons bed of the present invention, wherein the left side of fig. 1 shows the three-dimensional effect when the sofa is folded, and the right side of fig. 1 shows the three-dimensional effect when the Simmons bed is unfolded. Fig. 2 is a schematic structural view of the present invention with the right rear cover 3, the right front cover 4, the left rear cover 5 and the left front cover 6 removed, the left side view of fig. 2 is a schematic structural view when folded into a sofa, and the right side view of fig. 2 is a schematic structural view when extended into a spring bed. The parts in the figures are labeled as follows: 1 backrest plate, 2 seat plates, 3 right rear guard plates, 4 right front guard plates, 5 left rear guard plates, 6 left front guard plates, 7 oscillating rods, 8 connecting rods, 9 rear oscillating rods, 10 articulated shafts, 11 lead screws, 12 large gears, 13 small gears, 14 small motors, 15 motors, 16 cranks and 17 base frames.

Detailed Description

The present invention will be explained in detail with reference to the accompanying drawings, and referring to fig. 2, the present invention adopts the conventional mechanical four-bar mechanism to extend the sofa into the simmons bed, and the simmons bed is folded into the sofa to be freely and simply, and the left side of fig. 2 shows that the crank 16, the connecting rod 8, the swinging rod 7 and the base frame 17 form the four-bar mechanism, and the backrest plate 1, the swinging rod 7, the rear swinging rod 9 and the base frame 17 also form the four-bar mechanism. As can be seen from the left side of fig. 2, the backrest plate 1, which is now used as the backrest of the sofa, is defined by the fact that the swinging rod 7 and the rear swinging rod 9 are hinged to the base frame 17 at a position which makes the backrest slightly tilted backward perpendicularly to the ground, and when the position of the backrest plate 1, which is used as the sofa, is defined, the hinge shaft 10 of the backrest plate 1 is also defined, which makes the hinge shaft 10 at the left end of the seat plate 2 slightly tilted toward the backrest plate 1 when the sofa is in the sofa state, and this position is reliably defined in the left side of fig. 2 because the crank 16 and the connecting rod 8 are unfolded into a straight line state, that is, the angle between the crank 16 and the connecting rod 8 is 180 degrees, which ensures the position determination of the swinging rod 7 and thus the backrest plate 1 is fixed. When the sofa is converted into the Simmons bed, the motor 15 rotates clockwise, the crank 16 also rotates clockwise, and the connecting rod 8 pulls the swinging rod 7 to rotate clockwise; at this time, the clockwise action of the other set of four-bar linkage swinging rod 7 enables the backrest plate 1 to push the rear swinging rod 9 to also clockwise act, when the crank 16 rotates clockwise to the position of the right side drawing of the drawing 2, the two sets of four-bar linkages complete one action from the sofa to the Simmons bed, and the backrest plate 1 stretches into a horizontal state. During the movement of the back board 1 from the nearly vertical position to the horizontal position, the seat board 2 is pushed to move forward from the slightly inward inclined position to the horizontal position through the hinge shaft 10 between the back board 1 and the seat board 2. As can be seen from the right side of fig. 2, the back board 1 is also determined by the swing rod 7 and the other position of the rear swing rod 9 on the base frame 17, which is the position of the back board 1 on the ground level, and when the position of the back board 1 is determined as the simmons bed, the hinge axis 10 of the hinge point of the back board 1 and the seat board 2 is determined, which makes the left and right ends of the seat board 2 flush with the back board 1, and the position is reliably determined as seen from the right side of fig. 2 because the crank 16 and the connecting rod 8 are overlapped into a straight line state, namely the angle between the crank 16 and the connecting rod 8 is 0 degree, which ensures the position determination of the swing rod 7, and thus the back board 1 and the seat board 2 are fixed. In the left side of fig. 2, the seat plate 2 is slightly inclined inwards, in order to strengthen the stability of the position, a small motor 14 drives a small gear 13, and a large gear 12 drives a screw rod 11 to extend and retract to a fixed position. When the seat board 2 is horizontal in the right side of fig. 2, a small motor 14 is also used for driving a small gear 13 and a large gear 12 to enable a screw rod 11 to extend to another fixed position so as to ensure that the seat board 2 is stable and horizontal. When the sofa is folded from the Simmons bed, please refer to the right side of fig. 2, firstly, the small motor 14 drives the small gear 13 and the large gear 12 to retract the screw rod 11 to the lowest position, the motor 15 rotates counterclockwise to drive the crank 16 to rotate counterclockwise until the crank 16 and the connecting rod 8 are unfolded to be in a straight line, i.e. the state of the left side of fig. 2, at this time, the backrest plate 1 is already pulled back to be in the sofa state, and during the process of pulling back the backrest plate 1, the seat plate 2 is also pulled back to be in the sofa state through the hinge shaft 10 between the backrest plate 1 and the seat plate 2, i.e. the state of the left side of fig. 2. At this time, the small motor 14 also drives the small gear 13 and the large gear 12 to extend the screw rod 11 to a fixed position. From this point on the invention completes a cycle of action. The foregoing is merely an example of the present invention and various modifications and changes may occur to those skilled in the art, and it is intended to cover in the appended claims any and all changes that fall within the true spirit and scope of the invention.
