Herein, the terms used in the specification of the present invention are only for the purpose of describing specific embodiments, rather than limiting the present invention.

Embodiment 1

Reference is made to FIG. 1 to FIG. 4, the present invention discloses a storage bed including a bed body 1 provided with a storage cavity, a bed board frame 2 covering the bed body 1, parallelogram lifting mechanisms 3 symmetrically arranged on two sides of the bed board frame 2, and driving devices 4, wherein the parallelogram lifting mechanisms 3 are connected to inner side walls of the storage cavity and the bed board frame 2, and the driving devices 4 drive the parallelogram lifting mechanisms 3 to push the bed board frame 2 to be horizontally lifted towards a footboard direction of the bed body.
Therefore, the parallelogram lifting mechanisms 3 are utilized to push the bed board frame 2 to be horizontally lifted towards the footboard direction of the bed body 1, so that the bed board frame 2 is prevented from coming into collision against a headboard in a lifting process; it is unnecessary to take down bedclothes when articles are stored or taken, so that the storage bed is convenient to use; and meanwhile, after the bed board frame 2 is horizontally lifted, a larger operation space for storing or taking the articles can be ensured.
In this embodiment, each of the parallelogram lifting mechanisms 3 includes a fixed board 31, a supporting member 32, a first connecting rod 33, and a second connecting rod 34, wherein the fixed board 31 is arranged on the inner side wall of the storage cavity of the bed body 1, the supporting member 32 is arranged on the bed board frame 2, and two ends of both the first connecting rod 33 and the second connecting rod 34 are respectively hinged to the fixed board 31 and the supporting member 32. Therefore, each fixed board 31, the corresponding supporting member 32, the corresponding first connecting rod 33 and the corresponding second connecting rod 34 form a parallel four-connecting-rod structure to achieve the horizontal lifting of the bed board frame 2.
It may be understood that each fixed board 31, the corresponding supporting member 32, the corresponding first connecting rod 33 and the corresponding second connecting rod 34 are hinged with one another to form the parallel four-connecting-rod structure, and therefore, the distance among all hinge points is limited in the parallel four-connecting-rod structure. Specifically, if each fixed board 31 is hinged with the corresponding first connecting rod 33 by a hinge point A, each fixed board 31 is hinged with the corresponding second connecting rod 34 by a hinge point B, each supporting member 32 is hinged with the corresponding first connecting rod 33 by a hinge point C, and each supporting member 32 is hinged with the corresponding second connecting rod 34 by a hinge point D, a linear distance between the hinge point A and the hinge point B is equal to a linear distance between the hinge point C and the hinge point D, and a linear distance between the hinge point A and the hinge point C is equal to a linear distance between the hinge point B and the hinge point D. The relative distance relationship among all the above-mentioned hinge points is only required to be met, but specific shapes of the fixed boards 31, the supporting members 32, the first connecting rods 33 and the second connecting rods 34 are not limited.
In this embodiment, each fixed board 31 is provided with supporting legs 311 for supporting the ground. Therefore, a force borne by each fixed board 31 during lifting is not required to be completely transferred to the bed body 1 and may be partially supported by the corresponding supporting legs 311, and thus, the phenomenon that the fixed boards 31 are loosened or separated from the bed body 1 after being used for a long time is avoided. Specifically, three supporting legs 311 are provided, wherein two of the supporting legs 311 are connected to two ends of the fixed board 31, and another supporting leg is connected to a middle section of the fixed board 31. Actually, the positions and number of the supporting legs 311 arranged below the fixed board 31 are not specifically limited.
Preferably, each fixed board 31 and the corresponding supporting legs 311 are integrally formed, so that the strength is improved.
Preferably, the lower ends of the supporting legs 311 are horizontally bent to form supporting seats 312 by which a supporting surface is reinforced.

Specifically, each extension rod 331 is connected to the end, hinged with the corresponding fixed board 31, of the corresponding first connecting rod 33, a motor end of each electrically-driven push rod is hinged to the middle supporting leg 311 of the corresponding fixed board 31, and a telescopic end of each electrically-driven push rod is hinged to a tail end of the corresponding extension rod 331.

Moreover, in a use process of the storage bed, by energizing the electrically-driven push rods, the electrically-driven push rods start to stretch out and draw back and drive the first connecting rods 33 to rotate so as to push the bed board frame 2 to move in a lifting manner, then, the bed board frame 2 is lifted or drops to reset so as so expose or close the storage cavity of the bed body 1, and it is unnecessary to lift the bed board frame 2 with a hand, so that the storage bed is convenient to use; and the electrically-driven push rods are self-locked when being de-energized, so that the problem of sharp drop or locking incapability when the bed board frame 2 is opened is avoided, and high safety is achieved.

Reference is made to FIG. 4, in this embodiment, a reinforcing rod 332 is further arranged between each first connecting rod 33 and the corresponding extension rod 331. Specifically, two ends of each reinforcing rod are fixedly connected to the corresponding first connecting rod 33 and the corresponding extension rod 331 respectively to form a triangular supporting structure. By using the reinforcing rods 332, the strength of the extension rods 331 can be improved, and fatigue cracks and damage on a junction between each extension rod 331 and the corresponding first connecting rod 33 can be avoided.
Preferably, each first connecting rod 33, the corresponding extension rod 331 and the corresponding reinforcing rod 332 are integrally formed, so that the strength of its overall structure is further improved.
