[0042] Reference should be made to Figures 1 to 4 The folding bunk structure according to an embodiment of the present application has an unfolded state and a folded state, and includes a bed board and a bed mattress. The bed board includes a first board 110 and a second board 120. The bed mattress includes a first mattress 210 and a second mattress 220. The first board 110 is hingedly connected to the second board 120 at a first side in a width direction. A lower side surface of the first mattress 210 is in abutment with an upper side surface of the first board 110. An embedding groove 211 is formed in the lower side of the first mattress 210. The embedding groove 211 is open at a side of the first board 110 in the width direction. The second mattress 220 includes a spliced mattress 221 and an embedded mattress 222 which are fixedly connected to each other. The embedded mattress 222 is located at a side of the spliced mattress 221 in the width direction of the first board 110. When the folding bunk structure is in the folded state, the second board 120 is located in the embedding groove 211. When the folding bunk structure is in the unfolded state, the second board 120 is located in the same horizontal plane as the first board 110. The embedded mattress 222 is located in the embedding groove 211, and an upper side surface of the spliced mattress 221 is located in the same horizontal plane as an upper side surface of the first mattress 210.
[0043] It should be understood that when the folding bunk structure is in the folded state, the second board 120 is located in the embedding groove 211. When the folding bunk structure is in the unfolded state, the embedded mattress 222 is located in the embedding groove 211. The volume of the second board 120 and the volume of the embedded mattress 222 should both be not greater than the volume of the embedding groove 211. In actual application, the volume of the embedded mattress 222 and the volume of the second board 120 should be less than the volume of the embedding groove 211. In this way, when the folding bunk structure is switched between the folded state and the unfolded state, the second board 120 and the embedded mattress 222 can be easily assembled into the embedding groove 211.
[0044] It should be understood that the lower side surface of the first mattress 210 is in abutment with the upper side surface of the first plate 110, and the first plate 110 can provide support for the first mattress 210; when the folding bed is in the folded state, the second plate 120 is located in the embedded groove 211, at this time, the second plate 120 and the second mattress 210 are both located on the upper side of the first plate 110, and the first plate 110 provides support for both the second plate 120 and the second mattress 210. In a specific implementation, when the folding bed is in the folded state, the second mattress 220 is movably connected with the first mattress 210, and the second mattress 220 can be used alone, for example, as a temporary cushion, a seat cushion, etc. It should be noted that Figure 4 The reference figure is only a use state of the folding bed in the folded state, and is not limited to the position relationship between the second mattress 220 and other components of the folding bed in the folded state. In fact, the folding bed in the folded state does not affect the normal use. Specifically, the user can place the second bed at other places, and the user can still take a short rest on the first mattress 210 or lean on it for rest.
[0045] In the folding bed provided by the embodiment, the folding bed includes a bed plate and a bed mattress, the bed plate includes a first plate 110 and a second plate 120, and the bed mattress includes a first mattress 210 and a second mattress 220. When the folding bed is in the folded state, the second plate 120 is located in the embedded groove 211, so that in the width direction of the first plate 110, the second plate 120 and the second mattress 220 do not occupy space, and the folding bed occupies small space when in the folded state. When the folding bed is in the unfolded state, the second plate 120 is located in the same horizontal plane as the first plate 110, the embedded pad 222 is located in the embedded groove 211, the embedded pad 222 provides partial support for the first mattress 210, and the upper side surface of the spliced pad 221 is located in the same horizontal plane as the upper side surface of the first mattress 210. The bed plate can keep the bed mattress in a horizontal state and provide reliable support for the bed mattress. The first mattress 210 and the second mattress 220 as a whole provide rest for the user together, ensuring the lying needs of the user, and the second plate 120 and the second mattress 220 greatly increase the width of the folding bed, ensuring the comfort of the user when resting.
[0046] The folding bed provided by the embodiment has the following use process: referring to Figure 4, when the folding bunk is needed to be unfolded, the first mattress 210 is lifted on one side of the first side of the first board 110 in the width direction, the second board 120 is operated to rotate until the second board 120 is rotated out of the embedding groove 211 of the first mattress 210 and is rotated to the same horizontal plane as the first board 110, the second mattress 220 is moved, the embedding pad 221 of the second mattress 220 is operated to enter into the embedding groove 211, the second mattress 220 is translated towards the first mattress 210, the first mattress 210 is lowered on one side of the first side of the first board 110 in the width direction, and the positions between the first mattress 210 and the second mattress 220 are properly arranged and adjusted until the upper side of the splicing pad 221 is in the same horizontal plane as the upper side of the first mattress 210 and there is no large gap between the splicing pad 221 and the first mattress 210, so that the folding bunk is switched from the folded state to the unfolded state (see Figure 3 ) When the folding bunk in the unfolded state is needed to be folded, referring to Figure 3 , the first mattress 210 is lifted on one side of the first side of the first board 110 in the width direction, the embedding pad 221 of the second mattress 220 is translated away from the first mattress 210 until the embedding pad 221 is moved out of the embedding groove 211, the second mattress 220 is separated from the first mattress 210, then the second board 120 is operated to rotate until the second board 120 is rotated into the embedding groove 211, the first mattress 210 is lowered on one side of the first side of the first board 110 in the width direction, so that the folding bunk is switched from the unfolded state to the folded state, and at this time the second mattress 220 can be placed above the first mattress 210 or other places not occupying the width of the bed board.
[0047] The folding bunk provided by the embodiment can put or take out the embedding pad 221 of the second mattress 220 and the second board 120 of the bed board into or out of the embedding groove 211 of the first mattress 210 by lifting the first mattress 210 on one side of the first side of the first board 110 in the width direction during the switching process between the folded state and the unfolded state, and the movement amplitudes of the first mattress 210 and the second board 120 are small during the unfolding process or the folding process of the folding bunk, so that a larger space is not needed to be occupied, and therefore a larger space does not need to be designed and reserved in the carriage or the site to meet the space requirement of the folding bunk during folding or unfolding. In addition, the switching process of the folding bunk is simple and efficient, the structure is simple, and the market demand for lightweight vehicle interior products can be met.
[0048] Referring to Figures 1 to 4In some embodiments, the first and second pads 210 and 220 are both L-shaped in cross section; the first pad 210 comprises a first pad 212 and a second pad 213 which are perpendicular to and fixedly connected with each other, the upper side of the second pad 213 is in the same horizontal plane as the upper side of the first pad 212, the size of the first pad 212 is greater than that of the second pad 213 in the thickness direction of the first plate 110, and the area from the lower side of the second pad 213 to the lower side of the first pad 212 is configured as the embedding groove 211; the splicing pad 221 and the embedding pad 222 are perpendicular to each other, the lower side of the splicing pad 221 and the lower side of the embedding pad 222 are in the same horizontal plane, the size of the first pad 212 is equal to that of the splicing pad 221 in the thickness direction of the first plate 110, and the size of the embedding groove 211 is equal to that of the embedding pad 222; the size of the embedding groove 211 is equal to that of the embedding pad 222 in the width direction of the first plate 110.
[0049] It should be understood that the size of the embedding groove 211 is equal to that of the embedding pad 222 in the width direction of the first plate 110, the space of the embedding groove 211 is reasonably utilized under the premise that the size of the embedding groove 211 is constant, the embedding groove 211 is used to accommodate the embedding pad 222 when the folding bunk is in the unfolded state, and the embedding groove 211 is used to accommodate the second plate 120 when the folding bunk is in the folded state.
[0050] It should be understood that, because the cross sections of the first mattress 210 and the second mattress 220 are both L-shaped, the first mattress 210 includes the first pad 212 and the second pad 213 which are perpendicular to each other, the height of the first pad 212 is greater than the height of the second pad 213, and the area from the lower side of the second pad 213 to the lower side of the first pad 212 is configured as the embedding groove 211; the second mattress 220 includes the splicing pad 221 and the embedding pad 222 which are perpendicular to each other, along the width direction of the first plate 110, the size of the embedding groove 211 is equal to the size of the embedding pad 222, when the folding bunk is in the unfolded state, the embedding pad 222 is located in the embedding groove 211, along the thickness direction of the first plate 110, the size of the first pad 212 is equal to the size of the splicing pad 221, therefore, when the folding bunk is in the unfolded state, the first mattress 210 and the second mattress 220 can be overlapped and spliced, the area (i.e. the embedding groove 211) of the first pad 212 which is higher than the second pad 213 can be filled by the embedding pad 222, the embedding pad 222 is located at the bottom of the second pad 213 and is used to support the second pad 213. In addition, because the upper side of the first pad 212 and the upper side of the second pad 213 are flush, along the thickness direction of the first plate 110, the size of the first pad 212 is equal to the size of the splicing pad 221, therefore, when the folding bunk is in the unfolded state, the upper side of the splicing pad 221 is located in the same horizontal plane as the upper side of the first pad 212 and the upper side of the second pad 213, and the lower side of the splicing pad 221 can also be located in the same horizontal plane as the lower side of the first pad 212, thus, when the folding bunk is in the unfolded state, the upper and lower sides of the entire mattress are flat, providing a comfortable resting platform for the user.
[0051] In specific implementation, the first mattress 210 and / or the second mattress 220 can be an integrally formed structure, which is convenient for manufacturing and saves cost. The first mattress 210 and / or the second mattress 220 can also be a split structure which is fixedly connected, for example, the splicing pad 221 and the embedding pad 222 of the second mattress 220 can be fixedly connected by a magic tape or other fixed connection manner, thus, the state switching of the folding bunk is facilitated.
[0052] The folding bunk provided by the embodiment has the advantages that: the first mattress 210 and the second mattress 220 are simple in structure, the embedding groove 211 of the first mattress 210 and the embedding pad 222 of the second mattress 220 are simple in structure, the splicing process of the first mattress 210 and the second mattress 220 is simple and convenient, the switching efficiency between the folded state and the unfolded state of the folding bunk is improved, the user can use the folding bunk more conveniently and quickly, and thus the user experience is improved.
[0053] Referring to Figures 1 to 4 In some embodiments, along the width direction of the first plate 110, the size of the first pad 212 and the size of the second pad 213 are equal to the size of the first plate 110, and the side of the first plate 110 and the side of the first mattress 210 are located in the same vertical plane.
[0054] The folding bunk provided by the embodiment has the first pad 212 and the second pad 213 with a total size equal to the size of the first plate 110, and the side of the first plate 110 and the side of the first pad 210 are located in the same vertical plane, i.e., the size of the first plate 110 is equal to the size of the first pad 210 and the two sides are aligned, so that the folding bunk occupies as little space as possible in the width direction in the folded state on the premise that the first plate 110 can provide sufficient support for the first pad 210.
[0055] Referring to Figures 1 to 4 In some embodiments, when the folding bunk is in the unfolded state, along the width direction of the first plate 110, the side of the splicing pad 221 away from the embedded pad 222 is located in the same vertical plane as the side of the second plate 120 away from the first plate 110; along the width direction of the first plate 110, the size of the embedded groove 211 is equal to the size of the second plate 120.
[0056] It should be understood that, because along the width direction of the first plate 110, the size of the embedded groove 211 is equal to the size of the second plate 120, and the size of the embedded groove 211 is also equal to the size of the embedded pad 222, therefore, along the width direction of the first plate 110, the size of the second plate 120 is equal to the size of the embedded groove 211 and the size of the embedded pad 222. The area from the lower side of the second pad 213 to the lower side of the first pad 212 is configured as the embedded groove 211, so that along the width direction of the first plate 110, the size of the second pad 213 is equal to the size of the embedded groove 211, i.e., along the width direction of the first plate 110, the size of the second plate 120 is equal to the size of the embedded groove 211, the size of the embedded pad 222, and the size of the splicing pad 221.
[0057] Referring to Figure 3 and Figure 4In the process of switching from the folded state to the unfolded state of the folding bunk provided in the embodiment, the size of the bed board and the bed mat increases from the size of the first board 110 to the size of the sum of the first board 110 and the second board 120 along the width direction of the first board 110, and therefore, the width size of the second board 120 (or the spliced mat 222) determines the width space variation amount of the folding bunk in the switching process. In this way, under the premise that the size of the first mat 210 is certain, the size of the embedded groove 211 is also certain, the space of the embedded groove 211 can be reasonably utilized, the size of the second board 120 along the width direction of the first board 110 is as large as possible (not more than the size of the embedded groove 211 along the width direction of the first board 110), the width of the bed board can be increased, and along with the increase of the width size of the second board 120, the spliced mat 221 of the second mat 220 can also be adaptively increased. In the embodiment, the size of the embedded groove 211 along the width direction of the first board 110 is equal to the size of the second board 120, and under the premise that the size of the first mat 210 is certain, the size of the second board 120 is maximum, the width size of the folding bunk in the unfolded state is improved, and the user comfort is further improved.
[0058] Referring to Figure 1 , Figure 3 and Figure 4 In some embodiments, the second board 120 is connected with the first board 110 through the hinge 130, two hinge heads of the hinge 130 are fixedly installed on the upper surfaces of the first board 110 and the second board 120, in this way, the hinge connection of the first board 110 and the second board 120 is realized, and when the second board 120 rotates around the hinge shaft of the hinge 130, the interference between the first board 110 and the second board 120 can be reduced or even avoided.
[0059] Based on the same inventive concept, the application also provides a vehicle. The vehicle provided in the embodiment includes a vehicle cabin and the folding bunk of any one of the above embodiments of the application.

In this way, the second plate 120 is subjected to the action of the limiting piece 300, the load-bearing capacity of the second plate 120 can be improved, and the limiting piece 300 can limit the splicing pad 222, prevent the second pad 220 from moving away from the first pad 210, and improve the structural stability and use safety of the folding bunk bed.
[0064] In a specific implementation, the limiting piece 300 can be a drawstring. In a specific implementation, one end of the drawstring is connected to the vehicle compartment top, and the vehicle compartment top can be provided with a buckle.

After the folding bunk bed is unfolded, the other end of the drawstring is lowered and tied to the side of the second plate 120 away from the first plate 110. The drawstring can pull the second plate 120 away from the first plate 110, improve the load-bearing capacity of the second plate 120, and abut against the splicing pad 222 on the side of the splicing pad 222 away from the embedded pad 221, to prevent the splicing pad 222 from moving. Of course, the limiting piece 300 can also be a limiting support and the like.
[0065] Referring to Figure 4 and Figure 5 In some embodiments, the side of the first plate 110 and the first pad 210 on the second side in the width direction of the first plate 110 abuts against the side wall of the vehicle compartment; the first plate 210 is provided with a first connecting part on one side of the second side in the width direction of the first plate, and the side wall of the vehicle compartment is provided with a second connecting part. When the folding bunk bed is in the folded state, the first connecting part and the second connecting part are positionally corresponding and detachably fixedly connected, so that when the second pad 220 is placed on the first pad 210, the first pad 210 can be prevented from rolling down.
[0066] Referring to Figure 5 In some embodiments, the first connecting part and the second connecting part are connected in a Velcro pasting manner. The Velcro pasting can realize the detachable fixed connection between the second pad 220 and the first pad, and the Velcro pasting structure is simple, low in cost, and convenient to obtain and manufacture.
