Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, a foldable sofa bed comprises a sofa 1, wherein a receiving cavity 6 is formed in the lower surface of the sofa 1, an L-shaped chute 7 is formed in the inner side wall of the receiving cavity 6, a bed frame 4 is fixedly connected to the inside of the L-shaped chute 7 through a slider, a supporting plate 3 is arranged at one end of the bed frame 4, a first chute 12 is formed in the inner side wall of the supporting plate 3, a first spring 11 is fixedly connected to the inner wall of the first chute 12, a moving block 13 is fixedly connected to the upper end of the first spring 11, one side of the moving block 13 is fixedly connected to one end of a limiting block 14, a limiting mechanism is arranged inside the moving block 13, and a supporting mechanism is arranged on the lower surface of the other end of the bed frame 4.

As a technical optimization scheme of the utility model, stop gear includes electro-magnet 17, and the inner wall fixed connection of electro-magnet 17 and movable block 13, one side fixedly connected with second spring 15 of electro-magnet 17, and the one end fixedly connected with iron plate 16 of second spring 15, one side fixed surface of iron plate 16 is connected with stopper 14, and stopper 14 and movable block 13 sliding connection, the spacing hole 10 of multiunit has been seted up to the inside wall of first spout 12, and just spacing hole 10 is corresponding with stopper 14, mutually supports with the spacing hole 10 of first spout 12 inside wall through stopper 14 among the stop gear to can be spacing to carrying out of bedstead 4, thereby bedstead 4 glides downwards when someone lies or sits on bedstead 4.

As a technical optimization scheme of the utility model, supporting mechanism includes cylinder 8, and the upper end of cylinder 8 is connected with the lower fixed surface of bedstead 4, wheel 9 is removed to the lower extreme fixedly connected with of cylinder 8, and cylinder 8 can support the other end of bedstead 4 through supporting mechanism to the stability of bedstead 4 has further been improved.

As a technical optimization scheme of the utility model, the last fixed surface of bedstead 4 is connected with mattress 2, and mattress 2's thickness is the same with the distance of bedstead 4 to sofa 1's upper surface, the equal fixedly connected with curb plate 5 in both sides of sofa 1 for mattress 2 of bedstead 4 upper surface does not have the difference in height with sofa 1, thereby has improved sofa bed's comfort level.

When the utility model is used, firstly, the user pulls the bedstead 4 out of the containing cavity 6 by pulling the support plate 3, so that the mattress 2 can be moved out of the containing cavity 6, when the other end of the bedstead 4 moves to one end of the L-shaped sliding groove 7, the cylinder 8 is started at the moment, so that the other end of the bedstead 4 is lifted by the cylinder 8, meanwhile, one end of the bedstead 4 can be bounced by the elastic force of the first spring 11, at the moment, the mattress 2 on the upper surface of the bedstead 4 is level with the sofa 1, then the electromagnet 17 in the movable block 13 is closed, so that the second springs 15 on both sides of the electromagnet 17 can be bounced out of the movable block 13, so that the stopper 14 can be buckled in the limiting hole 10, so as to limit the bedstead 4, when the bedstead 4 needs to be folded, the electromagnet 17 is firstly electrified, so the electro-magnet 17 will adsorb stopper 14 in the inside of removal movable block 13, then will under starting cylinder 8 and making cylinder 8, and the user is pressing mattress 2 simultaneously to make under mattress 2 and the bedstead 4 will arrive the below of accomodating chamber 6, then to carrying out outage electro-magnet 17, thereby stopper 14 river lake buckle is in the inside of the spacing hole 10 of first spout 12 lower extreme, and later the user promotes backup pad 3 again, thereby it is enough with the inside of accomodating chamber 6 to take in bedstead 4 and mattress 2.
