[0002] A folding bed is a simple bed designed using the joint principle. For the sake of convenience and saving volume space, it can be folded and retracted through various folding methods, and is commonly used in places for temporary rest or with relatively compact spaces, such as on motorhomes, ships, or airplanes, etc. Taking a ship as an example, its overall volume is fixed. In order to increase its cargo space, it is necessary to reduce other spaces including its living area cabins. Generally, the cabins on ships are very small and can only hold very few things. Therefore, improving the space utilization rate of the cabins has become a major problem. Since the beds and cabinets in the cabins account for a large proportion, how to reduce the space area occupied by the beds has become the key to improving its space utilization rate. The traditional fixed-bed design has been difficult to meet the modern ship's demand for efficient space utilization, and the existing folding beds for ships generally only serve as beds, and still occupy a certain space after being folded. With the continuous progress of ship technology, the crew's requirements for living conditions have also been continuously improved. Most of the existing folding beds only serve as beds and can no longer meet the crew's requirements for living conditions. Content of the Utility Model

[0021] In order to better understand the purpose, structure and function of the present utility model, the following further describes in detail a double-layer folding bed of the present utility model with reference to the attached drawings.

[0022] As Figures 1-5 shown, the double-layer folding bed of the present utility model includes an upper bed body 1 and a lower bed body 2, which correspond to each other up and down. The lower bed body 2 is located at the lower side, and a corresponding support is provided below it to support the folding bed. The upper bed body 1 is suspended above the lower bed body 2, and corresponding back boards 3 are provided at the rear sides of both. The rear side of the lower bed body 2 is fixedly connected to the back board 3, and the rear side of the upper bed body 1 is rotatably connected to the back board 3. A corresponding support board 4 is provided between the upper bed body 1 and the lower bed body 2. The upper end of the support board 4 is connected to the bottom surface of the upper bed body 1, and the two are rotatably connected. Both the upper bed body 1 and the support board 4 can rotate around their respective rotation axes, so that they can be turned up and down. The folding bed realizes its deployment and contraction through the turning of the two. In this embodiment, both can rotate reciprocally 90° along the corresponding rotation axes. When it is in the deployed state, the support board 4 is erected between the lower bed body 2 and the upper bed body 1, providing support for the upper bed body 1. Cooperating with the back board 3, the upper bed body 1 is suspended above the lower bed body 2. At this time, both the upper bed body 1 and the lower bed body 2 are parallel to the horizontal plane and can both be used as beds for people. When the folding bed is in the contracted state, the bottom surface of the upper bed body 1 fits on the back board 3, and the support board 4 contracts between the lower bed body 2 and the back board 3. At this time, the lower bed body 2 serves as a sofa cushion, and the upper bed body 1 cooperates with it as the backrest of the sofa. Such a design enables the folding bed to change its form between a bed and a sofa to meet the different living needs of users, and further improves the space utilization rate of the folding bed.

[0023] The upper bed body 1 includes an upper shelf board 11. Above the upper shelf board 11, a corresponding upper bed board 12 is provided. The two correspond to each other and are fixedly connected. A corresponding fixed frame 13 is provided on the periphery of the two. The fixed frame 13 surrounds the periphery of the upper shelf board 11 and the upper bed board 12. Its inner circle is fixedly connected to the periphery of the upper shelf board 11 and the upper bed board 12. The rear end of the fixed frame 13 is connected to the back board 3. In this embodiment, the rear side edge of the bottom surface of the fixed frame 13 is rotatably connected to the upper part of the front side wall of the back board 3. The upper bed body 1 can reciprocally rotate 90° along the rotation axis between the two, so that it can turn and change up and down in the front-back direction, and further realize the change between the horizontal and vertical placement states. On the left and right sides below the upper bed body 1, a corresponding pair of support plates 4 are provided. The upper ends of the two support plates 4 are respectively rotatably connected to the left and right sides of the bottom surface of the fixed frame 13. The rotation of the two support plates 4 along the corresponding rotation axis realizes the change between horizontally contracting towards the inside of the upper bed body 1 and vertically expanding towards the left and right sides of the upper bed body 1, so as to realize the change between the contracted and expanded states. When the support plate 4 is in the expanded state, its top end abuts against the bottom surface of the fixed frame 13, and its bottom end abuts against the lower bed body 2, so as to provide a supporting force for the upper bed body 1 above it.

[0024] Furthermore, a corresponding anti-fall handrail 5 is provided on the outer side of the upper bed body 1, which can prevent the user from slipping off the edge of the upper bed body 1 during use, improving the safety of the folding bed. The bottom end of the anti-fall handrail 5 is connected to the front end of the upper surface of the fixed frame 13, and the two are rotatably connected. The anti-fall handrail 5 can rotate along the corresponding rotation axis, so as to cooperate with the unfolding or contraction of the folding bed.

[0025] The lower bed body 2 includes a lower shelf board 21 and a lower bed board 22. Among them, the lower bed board 22 is provided on the lower shelf board 21. Both of them correspond to the upper bed body 1 and are fixedly connected between them. The upper surface of the lower bed board 22 serves as a working surface for the user to rest. Below the lower shelf board 21, a corresponding cabinet 23 is provided. The bottom surface of the lower shelf board 21 is attached to the top surface of the cabinet 23, and the two are detachably connected. The cabinet 23 is a box-shaped cabinet with a hollow interior and an upward opening, which plays a role of a bracket below the lower shelf board 21 and provides a supporting force for the folding bed. The hollow inner cavity of the cabinet 23 is divided into multiple storage compartments for storing items. In this embodiment, the storage compartments include a storage cabinet and two storage drawers. The storage cabinet is provided at one end of the cabinet 23, and its interior is hollow and has an upward opening, with the corresponding end of the lower shelf board 21 serving as a box cover. The two storage drawers are arranged side by side adjacent to each other on the other end of the cabinet 23 opposite to the storage cabinet. The pulling ends of the two storage drawers are both provided on the front side wall of the storage cabinet. This design increases the storage space of the folding bed, makes more full use of the space under the bed, and improves the utilization rate of the space of the folding bed. The rear side board of the cabinet 23 extends upward as the back board 3 to provide a supporting function for the upper bed body 1.

[0026] Further, the lengths of the left and right ends of the lower shelf board 21 and the lower bed board 22 corresponding to the support board 4 correspond to the lengths of the corresponding inner cavity of the cabinet 23. The wall boards on the left and right sides of the cabinet 23 corresponding to the support board 4 extend upward to a height higher than the lower bed board 22. At the top ends of the extended left and right side wall boards, a groove 25 corresponding to the bottom end of the support board 4 is provided respectively. When the support board 4 is unfolded, its bottom end is embedded in the groove 25 of the corresponding side wall board of the cabinet 23. While the side wall board of the cabinet 23 corresponding to the support board 4 provides a supporting effect for the support board 4, it also plays a role of limiting and guiding in the front-back direction. A pair of corresponding vertical boards 24 are provided on the left and right sides of the cabinet 23. The two vertical boards 24 are fixedly connected to the corresponding side wall boards of the cabinet 23. The inner side surfaces of the two vertical boards 24 are respectively attached to the outer side surfaces of the corresponding side wall boards of the cabinet 23. The top surface of the vertical board 24 is higher than the top surface of the corresponding groove 25. The vertical board 24 provides a limiting effect for the support board 4 when the support board 4 is unfolded.

[0027] Further, all components of the folding bed are made of lightweight metal materials. In this embodiment, aluminum honeycomb panels are used, which can not only prevent fire and water, but also are lighter in weight, more labor-saving during transportation, and consume less energy during transportation compared with other materials of the same volume, thus saving more energy. A strong magnetic attraction 14 corresponding to the two support boards 4 is provided on the bottom surface of the upper shelf board 11, which can suck the support board 4 when the support board 4 is in a horizontal contracted state, effectively preventing it from falling off during contraction. The upper surfaces of the upper bed board 12 and the lower bed board 22 are used as their working surfaces and are made of flexible materials, improving the comfort of their use.

[0028] Further, the double-layer folding bed of the present utility model further includes a ladder 6 corresponding to its upper bed body 1. The ladder 6 is telescopic. When the folding bed is in an unfolded state, the unfolded ladder 6 can be arranged on the front side of the folding bed. The ladder 6 is inclined relative to the folding bed, its bottom end abuts against the ground where the folding bed is installed, and its upper end is placed on the front side of the upper bed body 1. After being set up, it can be used by the user to get on and off the upper bed body 1. When the folding bed is not used as a bed body, the ladder 6 can be contracted and placed in the cabinet 23 for storage.

[0029] When in use, the double-layer folding bed of the utility model has two forms, a sofa and a bed. When it is used as a bed, all its components are adjusted to the unfolded state. First, the upper bed body 1 is rotated around the rotation axis corresponding to the back plate 3, and it is adjusted to a horizontal state so that it is parallel to the lower bed body 2. Then, the two support plates 4 are flipped and opened to the left and right sides around their corresponding rotation axes so that they are vertically supported between the upper bed body 1 and the lower bed body 2. At the same time, the anti-fall armrest 5 is rotated and adjusted to a vertical position above the upper bed body 1 and perpendicular to its upper surface. The ladder 6 is unfolded and placed in an appropriate position in front of the folding bed for easy access. At this time, the folding bed can be used as a double-layer bed. The bed is in use and when it is finished and needs to be converted to a sofa state, first, the ladder 6 on the front side of the folding bed is retracted and placed, and then the two support plates 4 are flipped around their corresponding rotation axes to the inside of the folding bed. After flipping, the inner side surface of the support plate 4 is attached to the bottom surface of the upper bed body 1 as its upper surface and is attracted by the strong magnetic attraction 14, so it is not easy to fall. Then, the upper bed body 1 is flipped downward around its corresponding rotation axis, and the outer side surface of the support plate 4 is attached to the front side wall of the back plate 3 as its bottom surface after flipping. At the same time, the anti-fall armrest 5 is adjusted to be parallel to the upper bed body 1. At this point, the folding bed is completely retracted and it can be used as a sofa.

[0030] The double-layer folding bed of the utility model can be switched between a bunk bed and a sofa by flipping and folding the upper bed body 1 and the support plate 4. This design allows the folding bed to still be used as furniture after being folded, thereby improving the utilization rate of space. At the same time, it also increases the user's usage options, making the living conditions of the space better and meeting the user's requirements for higher living conditions.
