For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood through specific situations.

[0026] Such as Figures 1 to 4As shown in the figure, a double - layer linkage folding bed cabinet can make the upper and lower beds of the double - layer folding bed unfold and fold synchronously. The operation method is convenient, the unfolding and folding method is simple, and the safety is high. The folding bed cabinet of this embodiment includes a cabinet body 1, an upper bed frame 2 and a lower bed frame 3 which are sequentially installed in the cabinet body 1 from top to bottom. Rotating shafts 4 horizontally connected to the inner walls on both sides of the cabinet body 1 are provided on both sides of the upper bed frame 2 and the lower bed frame 3, so that the upper bed frame 2 and the lower bed frame 3 can be rotated into the cabinet body 1 through the rotating shafts 4 for closing or flipped out of the cabinet body 1 through the rotating shafts 4 for unfolding. In order to realize the synchronous unfolding and folding of the upper bed frame 2 and the lower bed frame 3 and simplify the unfolding operation of the double - layer folding bed, a linkage rod 5 is provided between one ends of the upper bed frame 2 and the lower bed frame 3 located in the cabinet body 1 in this embodiment. When the upper bed frame 2 or the lower bed frame 3 is rotated through the rotating shaft 4 for unfolding or closing, the lower bed frame 3 or the upper bed frame 2 can be synchronously rotated under the linkage of the linkage rod 5, thereby realizing the linkage unfolding and folding of the upper bed frame 2 and the lower bed frame 3, and effectively improving the unfolding and folding efficiency of the double - layer folding bed.

[0027] As Figures 2 to 4 shown, a driving mechanism 6 connected to one end of the upper bed frame 2 located in the cabinet body 1 is provided at the inner wall of the cabinet body 1 of this embodiment, so that the upper bed frame 2 and the lower bed frame 3 can be automatically unfolded or folded under the drive of the driving mechanism 6. The unfolding and folding method is simple and the safety is high. Specifically, the driving mechanism 6 of this embodiment includes a mounting frame 61 provided on the inner wall of the cabinet body 1 and an electric push rod 62 connected to the mounting frame 61. The electric push rod 62 of this embodiment is longitudinally arranged. The tail end of the electric push rod 62 is rotatably connected to the mounting frame 61. At the same time, a connecting portion 7 is provided at one end of the upper bed frame 2 and the lower bed frame 3 located in the cabinet body 1. The other end of the electric push rod 62 is rotatably connected to the connecting portion 7. Thus, when the electric push rod 62 is started to extend its telescopic rod, one end of the upper bed frame 2 located in the cabinet body 1 can be pushed and rotated downward around the rotating shaft 4, so that one end of the upper bed frame 2 located outside the cabinet body 1 rotates upward around the rotation and fits into the cabinet body 1 to realize the automatic closing of the upper bed frame 2; and, both ends of the linkage rod 5 of this embodiment are respectively rotatably connected to the connecting portions 7 of the upper bed frame 2 and the lower bed frame 3. Thus, when the upper bed frame 2 is automatically folded into the cabinet body 1 under the action of the electric push rod 62, the linkage rod 5 can be pushed downward by one end of the upper bed frame 2 located in the cabinet body 1, so that one end of the lower bed frame 3 located in the cabinet body 1 rotates downward around the rotating shaft 4, and further realizes that one end of the lower bed frame 3 located outside the cabinet body 1 rotates and closes into the cabinet body 1 around the rotating shaft 4, thereby realizing the synchronous folding of the upper bed frame 2 and the lower bed frame 3; conversely, when the electric push rod 62 is started to contract its telescopic rod, the upper bed frame 2 and the lower bed frame 3 can be respectively rotated around their respective rotating shafts 4 to unfold from the cabinet body 1, realizing the automatic unfolding of the upper bed frame 2 and the lower bed frame 3.

[0028] In other embodiments, the electric push rod 62 can also be connected to one end of the lower bed frame 3 located in the cabinet body 1, and the same technical effects as those in the above - mentioned embodiments can also be obtained, which will not be elaborated here.

[0029] As Figure 2 and Figure 4 shown, at the positions on the inner side wall of the cabinet body 1 of this embodiment corresponding to the upper bed frame 2 and the lower bed frame 3, longitudinally arranged auxiliary cylinders 8 are provided. One end of the auxiliary cylinder 8 is rotatably connected to the inner side wall of the cabinet body 1, and the other end is rotatably connected to the connecting part 7 of the upper bed frame 2 or the lower bed frame 3. When the upper bed frame 2 and the lower bed frame 3 are unfolded or folded, the auxiliary cylinder 8 can provide additional supporting force for the unfolding and closing of the double-layer folding bed, making the folding and unfolding processes smoother and safer.

[0030] As Figures 1 to 3 shown, a linkage ladder 9 for linking the upper bed frame 2 and the lower bed frame 3 on the outside is connected between the ends of the upper bed frame 2 and the lower bed frame 3 located outside the cabinet body 1 of this embodiment. The upper bed frame 2 and the lower bed frame 3 can also be linked through the linkage ladder 9 to achieve synchronous unfolding and closing actions, and the linkage ladder 9 also provides a passage between the lower bed frame 3 and the upper bed frame 2, enabling users to climb onto the upper bed frame 2 through the linkage ladder 9 for use.

[0031] Specifically, as Figure 1 and Figure 2 shown, the linkage ladder 9 of this embodiment includes a first upright post 91 and a second upright post 92 vertically connected to the side walls of the upper bed frame 2 and the lower bed frame 3 in sequence from outside to inside, and several cross-bar pedals 93 connected between the first upright post 91 and the second upright post 92. Both ends of the first upright post 91 and the second upright post 92 are rotatably connected to the side wall of the upper bed frame 2 and the side wall of the lower bed frame 3 respectively, and both ends of the cross-bar pedals 93 are rotatably connected to the first upright post 91 and the second upright post 92 respectively. In this embodiment, the upper bed frame 2 is used as the actively rotating bed frame. When the upper bed frame 2 rotates and unfolds inside the cabinet body 1, the first upright post 91 and the second upright post 92 can be driven by the upper bed frame 2 to rotate and drive the lower bed frame 3 to unfold, thereby achieving the linkage effect of the upper bed frame 2 and the lower bed frame 3. At the same time, the cross-bar pedals 93 can also be driven by the first upright post 91 and the second upright post 92 to be horizontally connected between the first upright post 91 and the second upright post 92, and then form the linkage ladder 9 connecting the upper bed frame 2 and the lower bed frame 3, facilitating users to climb onto the upper bed frame 2 for use; conversely, when the upper bed frame 2 rotates and folds into the cabinet body 1, the first upright post 91 and the second upright post 92 can also drive the lower bed frame 3 to perform synchronous folding operations, and the first upright post 91 and the second upright post 92 approach each other under the drive of the lower bed frame 3. At the same time, the cross-bar pedals 93 rotate and are longitudinally connected between the first upright post 91 and the second upright post 92 under the drive of the first upright rod and the second rod, so that the first upright post 91, the second upright post 92 and the cross-bar pedals 93 are all vertically on the sides of the upper bed frame 2 and the lower bed frame 3, realizing the folding of the linkage ladder 9 without manual folding operation, with a convenient operation method and effectively improving the unfolding and closing efficiency of the double-layer folding bed.

[0032] Furthermore, asFigure 1 and Figure 4 As shown in Figure 4 , in order to reduce the volume of the linked ladder 9 after folding and improve the folding effect of this embodiment, mounting grooves are provided on the opposite surfaces of the first vertical column 91 and the second vertical column 92 along their respective lengths. The thickness of the crossbar pedal 93 is adapted to the structure of the mounting grooves, and both ends of the crossbar pedal are respectively inserted into the mounting grooves of the first vertical column 91 and the second vertical column 92. When the folding ladder main body is folded, the crossbar pedal 93 can be driven by the first vertical column 91 and the second vertical column 92 to turn longitudinally and fit into the mounting grooves, thereby effectively reducing the volume of the folding ladder main body after folding and facilitating the hiding of the double-layer folding bed after folding.

[0033] As Figure 1 and Figure 3 shown in Figure 3 , this embodiment can also manually realize the unfolding and closing of the upper bed frame 2 and the lower bed frame 3. Specifically, a handle 94 for manually unfolding or closing the folding ladder main body is provided at the front end of the first vertical column 91 of this embodiment. The user can pull the handle 94 to rotate the first vertical column 91 and the second vertical column 92, and then drive the upper bed frame 2 and the lower bed frame 3 to rotate and unfold in the cabinet 1, thereby realizing the unfolding of the double-layer folding bed; conversely, the user can push the first vertical column 91 through the handle 94 to make the first vertical column 91 and the second vertical column 92 approach each other, so that the upper bed frame 2 and the lower bed frame 3 rotate and fold in the cabinet 1 to realize the closing of the double-layer folding bed. By providing the handle 94 in this embodiment, the situation where the upper bed frame 2 and the lower bed frame 3 cannot be unfolded or closed in the case of power failure can be avoided.

[0034] As Figure 1 and Figure 2 shown in Figure 2 , one end of the first vertical column 91 of this embodiment connected to the lower frame body extends to the bottom of the lower frame body to form a support leg 911 for supporting the upper bed frame 2 and the lower bed frame 3 after unfolding. After the lower bed frame 3 is horizontally unfolded, the support leg 911 can abut against the ground to support the lower bed frame 3. An adjusting screw 912 for adjusting the support height is provided at the bottom of the support leg 911 of this embodiment. By adjusting the adjusting screw 912, different ground conditions can be adapted, and the stability of the double-layer folding bed after unfolding in this embodiment can be further enhanced.

[0035] As Figures 1 to 2 shown in Figures 1 to 2 , in order to increase the safety of use, a guardrail 21 is provided at the outer side of the upper bed frame 2 of this embodiment to prevent the user from falling from the upper bed frame 2.

[0036] As Figure 2 and Figure 4 shown in Figure 4 , bed boards are installed at the bottoms of both the upper bed frame 2 and the lower bed frame 3 of this embodiment. After the upper bed frame 2 and the lower bed frame 3 are folded into the cabinet 1, the bed boards can cover the surface of the cabinet 1, thereby improving the aesthetics after folding of this embodiment.

[0037] In summary, the working principle of this embodiment is as follows: In this embodiment, the upper bed frame 2 and the lower bed frame 3 are rotatably installed in the cabinet body 1 in sequence from top to bottom, and a linkage rod 5 is arranged at one end of the upper bed frame 2 and the lower bed frame 3 located in the cabinet body 1. When the upper bed frame 2 or the lower bed frame 3 rotates in the cabinet body 1 for unfolding or folding, the linkage rod 5 can link the upper bed frame 2 and the lower bed frame 3 so that the upper bed frame 2 and the lower bed frame 3 move synchronously, thereby realizing the synchronous folding or unfolding of the upper bed frame 2 and the lower bed frame 3, and the operation method is convenient; moreover, in this embodiment, a driving mechanism 6 rotatably connected to the upper bed frame 2 or the lower bed frame 3 is arranged on the inner wall of the cabinet body 1, so that the upper bed frame 2 or the lower bed frame 3 can rotate around the rotating shaft 4 under the push of the driving mechanism 6, and at the same time, the upper bed frame 2 and the lower bed frame 3 are automatically unfolded or folded under the linkage of the linkage rod 5. The unfolding and folding method is simple and has high safety.

[0038] The embodiments described above are only the preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby. Any non-substantive changes and modifications made by those skilled in the art on the basis of the present invention shall fall within the protection scope of the present invention.
