An inclined transition section 223 is between the high-end section 221 and the low-end section 222, and reinforcing plates 25 are welded to the lower side of the low-end section and the transition section, and to the transition section and the high-end section. The high-end section 221 of the support frame is evenly distributed with bolt holes, and is fixedly connected to the small mattress assembly 6 by bolts. The low-end section 222 of the support frame is used to set the swing mechanism 3, and the other end of the swing mechanism 3 is hinged and fixed to the bottom of the large mattress assembly 7.

[0036] In this embodiment, under the action of external force, the swing mechanism 3 pulls the large mattress assembly 7 to swing at the inner and outer ends of the support frame. When swinging toward the inner end of the support frame, the swing mechanism 3 pulls the large mattress assembly 7 to rotate inward so that its inner end covers the small mattress assembly, the inner end surface is flush with the small mattress assembly 6, and the outer end extends outward along the same plane, forming the first position of the minimum width of the berth assembly; when swinging toward the outer side of the support frame, the swing mechanism 3 pulls the large mattress assembly 7 to rotate outward and fall back to the lower end section of the laying section, so that the inner end surface is abutted against the outer end surface of the small mattress assembly 6, and the outer end extends outward along the same plane, forming the second position of the maximum width of the berth assembly.

[0037] like Figure 3 and Figure 4 As shown, in this embodiment, the swing mechanism 3 includes a connecting rod and a limit block, one end of the connecting rod is rotatably connected to the lower end section 222 of the support frame, the other end of the connecting rod is rotatably connected to the bottom of the large mattress assembly 7, the limit block is fixed to one end of the hinged support frame of the connecting rod, and the limit block has a limit surface that limits the connecting rod to remain in the first position or the second position. In terms of specific structure, two parallel connecting rods are arranged between the support frame 2 and the large mattress assembly 7, the lower end section 222 of the support frame is hinged to the lower end of the connecting rod through a connecting seat, and the bottom of the large mattress assembly 7 is rotatably connected to the upper ends of the two connecting rods through a large mattress connecting plate 35. In order to facilitate the installation and disassembly of the two connecting rods, the integral folding vertical plate of the support frame is used as a connecting seat for connecting the connecting rods, or as shown in the figure of this embodiment, the lower end section 222 of the support frame is divided into two parts, the side close to the transition section is integrated with the support frame as the lower end section, the outer side of the lower end section is fixed with a connecting seat by bolts, and the lower ends of the two connecting rods are hinged to the vertical plate of the connecting seat.

The auxiliary limiting block 34 is located on the side of the connecting rod adjacent to the small mattress assembly 6 and is provided with an auxiliary limiting surface 341 that keeps the two connecting rods in the first position.

[0039] In order to lock the large mattress assembly in position after stretching, a swing locking structure is provided between the swing mechanism 3 and the large mattress assembly 7. Figure 4 and Figure 7 As shown, in this embodiment, the swing locking structure includes a lock hook 24 fixed on the swing mechanism connection seat, and a latch 902 with a lock tongue correspondingly mounted on the bottom of the large mattress assembly. The latch can adopt an existing structure, and when the berth assembly is in the first position, the lock tongue can be locked in the lock hook 24, thereby realizing the limit of the first position.

[0040] In order to drive the locking tongue and the locking hook 24 out of engagement so as to swing to the second position, in this embodiment, a locking member is provided at the outer end of the large mattress assembly as follows: Figure 5 The handle assembly 9 shown in the figure has a rotation unlocking assembly disposed between the handle assembly and the lock tongue. In this embodiment, the rotation unlocking assembly includes a handle button 904 disposed on the handle assembly, and a pull line 903 connected between the handle button and the lock tongue. Under the drive of an external force, the handle button 904 is pulled to rotate outward, and the handle shaft 907 connected to the handle button 904 overcomes the elastic force of the handle spring 908 to cause the pull line 903 of the lock tongue to be pulled, so that the lock tongue overcomes the action of its reset spring and is disengaged from the engagement with the lock hook 24. After leaving the first position, the handle button 904 is acted upon by the handle spring 908 at the handle shaft, and the lock tongue is acted upon by the reset spring at the lock position, and each is reset.

[0041] In order to provide a more stable experience, in this embodiment, the support frames 2 are arranged in two parallel groups, and a stabilizing rod 23 is fixedly connected between the connecting sections of the two groups of support frames.

[0042] In this embodiment, the support frame can be directly fixed to the vehicle body by bolts or welding, but in order to facilitate the berth frame to be flipped and folded when not in use to reduce the occupied space, Fig.11 Combination Figure 7-Figure 8 As shown, below the berth assembly is a vehicle body base 12, the upper end of the connecting section of the support frame 2 is rotatably connected to the side wall of the vehicle body through a rotating shaft and a hinged support 4, and a second gas strut 8 is hinged between the laying section of the support frame and the vehicle body base to position the overall flipping of the berth assembly to provide a larger interior space.

[0043] In this embodiment, a rotation locking structure is provided between the berth assembly and the vehicle body base. Figure 1 As shown, the rotation locking structure includes a bead seat 83 fixed to the vehicle body base, and a bead 82 fixed to the support frame or the large mattress assembly. When the berth assembly is subjected to external force, it overcomes its own gravity and the friction of the bead seat, and the bead leaves the bead seat, and the second gas support supports the berth assembly to flip to a set angle.

[0044] In order to improve the comfort of the berth assembly, a number of support columns 5 are fixed below the large mattress assembly, and a number of bottom support blocks 13 can also be fixed to the vehicle body base. The support column is an I-shaped column structure, the top plate of the support column is fixedly connected to the large mattress assembly by bolts, the middle column of the support column is composed of opposite side plates and reinforcing ribs welded therein and distributed in a continuous fold line, and the bottom of the middle column is welded to the bottom of the bottom plate.

[0045] Example 2

[0046] The difference between this embodiment and embodiment 1 is that in this embodiment, no vehicle body base is provided below the berth assembly. The connecting section of the support frame is rotatably connected to the laying section, and the second gas strut is connected between the laying section and the vehicle body side wall below the connecting section. A rotation locking structure is provided between the laying section and the vehicle body side wall. The berth assembly is pulled by the second gas strut and has a retracted state in which the laying section fits the vehicle body side wall, so as to provide a larger space. The berth assembly is supported by the second gas strut and has a laying state in which the laying section is perpendicular to the vehicle body side wall, providing a resting space. It is further preferred to provide a second auxiliary support between the vehicle body side wall and the unfolded laying section.

[0047] Similarly, another method is to extend a support plate outward from the lower end of the connecting section, and install a second air strut between the outer side of the support plate and the upper vehicle body side wall of the connecting section, so that the large mattress assembly has two states: flat and folded upward.

[0048] Example 3

[0049] The difference between this embodiment and embodiment 1-2 is that in this embodiment, the swing mechanism includes a first gas strut and a spring, the two ends of the first gas strut are respectively hinged to the laying section of the support frame and the bottom of the large mattress assembly, and the spring is connected between the laying section of the support frame and the large mattress assembly in parallel with the first gas strut. In this design, the laying section of the support frame can be simplified to a horizontal structure.
