The cab body 8 is provided with a middle seat 4, the middle seat 4 includes a pivotally connected backrest 401 and a seat cushion 402, the backrest 401 can be flipped to the upper part of the seat cushion 402, and berth blocks 1 2 and berth blocks 2 1 are provided on both sides of the middle seat 4. When the backrest 401 is flipped, the backrest 401 is flush with the berth block 1 2 and the berth block 2 1, and a support assembly is provided in the cab body 8, and the support assembly is used to support the berth block 1 2 and the berth block 2 1.

[0037] This specific embodiment arranges the deformable middle seat 4 between the berth block 1 2 and the berth block 2 1 , so that the middle seat 4 and the berth can be converted into each other according to the required functions, avoiding the two being arranged independently and occupying a large space.

[0038] like Figure 3 and Figure 4As shown, in order to leave enough layout space for the chassis, in the present specific embodiment, an upward protrusion is provided in the middle of the floor, and the protrusion includes a front part 9 and a rear part 13, the rear part 13 is higher than the front part 9, the middle seat 4 is arranged on the rear part 13, the baffle 7 is arranged at the connection between the front part 9 and the rear part 13, and a driving seat and a co-pilot seat are respectively arranged on both sides of the front part 9. In the present specific embodiment, the middle seat 4 is arranged close to the berth block 2; in order to achieve reliable support for the middle seat 4, a mounting frame 405 is provided at the lower part of the seat cushion 402, and the lower part of the mounting frame 405 is inclined backward, and the mounting frame 405 is detachably connected to the front surface of the rear part 13 by bolts, and the mounting bracket, the front surface of the rear part 13 and the front end of the seat cushion 402 form a triangular support structure, which enhances the supporting strength of the middle seat 4.

[0039] like Figure 3 and Figure 4 As shown, in this specific embodiment, a berth block 3 is also provided in the cab body 8. The berth block 3 is located behind the middle seat 4. The berth block 3 is squeezed between the seat cushion 402 and the cab body 8, and the lower surface abuts against the rear portion 13 to achieve support.

[0040] like Figures 1 to 4 As shown, in the present specific embodiment, the berth block 1 2 and the berth block 2 1 are limited by elastic deformation caused by the abutment with the cab body 8 and the middle seat 4. In order to achieve uniform support for the berth block 1 2 and the berth block 2 1 and prevent them from being skewed by force and affecting the safety of lying down, in the present specific embodiment, the support assembly can adopt the following specific structure: the support assembly includes a baffle 7, a support plate 10, a cushion block 5, a support seat 1 6 and a support seat 2 11. The baffle 7 is vertically arranged on the floor of the cab body 8 and is connected to the floor by bolts. A groove is arranged on the upper part of the baffle 7, and the groove is used to accommodate the cushion 402. The upper part of the baffle 7 abuts against the front end of the lower surface of the berth block 1 2 and the berth block 2 1. The support plate 10 is a triangular structure. The support plate 10 is arranged between the baffle 7 and the floor. The plate 10 can play a good supporting role on the baffle 7 to prevent the baffle 7 from being skewed by force and affecting its supporting function. The support seat 16 and the support seat 2 11 are arranged on the rear side of the cab body 8, the support seat 16 abuts against the lower surface of the berth block 2, the support seat 2 11 abuts against the lower surface of the berth block 21, and the cushion block 5 is arranged at the rear part 13 of the floor and is located on one side of the cushion 402, the cushion block 5 abuts against the lower surface of the berth block 2 or the berth block 21. Since in this specific embodiment, the middle seat 4 is arranged close to the berth block 2, the cushion block 5 abuts against the lower surface of the berth block 21; through the action of the baffle 7, the support seat 16 and the support seat 2 11, support is formed on the front and rear sides of the corresponding berth block, which effectively prevents the berth block from being skewed after being subjected to force (for example, when a person just sits on the front part 9 of the berth block or turns over), thereby improving the safety of lying down.

[0041] like Figure 5As shown, preferably, in order to further prevent the berth block 1 2 and the berth block 2 1 from tilting on the left and right sides, in the present specific embodiment, berth brackets 404 are respectively welded on both sides of the seat cushion 402, and the berth brackets 404 are in a Z-shaped structure, and the berth brackets are in contact with the berth block 1 2 or the berth block 2 1; the berth brackets 404 support the berth block 1 2 and the berth block 2 1 near the middle, that is, the position where the force is applied when the person lies down, which can effectively prevent the berth block 1 2 or the berth block 2 1 from tilting at one end under the action of people, thereby further improving the safety of lying down.

[0042] In order to greatly improve the utilization rate of the internal space of the cab, in the present specific embodiment, the inner wall of the cab body is provided with a lining, the baffle 7, the berth block 1 2, the rear portion 13 and the corresponding lining form a toolbox 1, and the berth block 2 is equivalent to the lid of the toolbox 1, the baffle 7, the berth block 2 1, the rear portion 13 and the corresponding lining form a toolbox 2, and the berth block 2 1 is equivalent to the lid of the toolbox 2; at the same time, in the present specific embodiment, support points are arranged only on three sides of the berth block 1 2 and the berth block 2 1, so that the corresponding toolbox can be opened by applying downward pressure to the end of the berth block 1 2 and the berth block 2 1 without a support point; when it is necessary to take and put tools, the corresponding toolbox can be opened by opening the berth block 1 2 and the berth block 2 1.

[0043] like Figure 6 As shown, in this specific embodiment, the backrest 401 and the seat cushion 402 are pivotally connected by a horizontally arranged rotating shaft, and the middle seat 4 is also provided with a locking mechanism, which includes a connecting piece 1 4031 on the backrest 401, a connecting piece 2 4032 on the seat cushion 402, an adjustment handle 4033, an intermediate block 4034, a shifting block 4035 and a spring 4036, wherein the intermediate block 4034 is rotatably connected to the connecting piece 1 4031 by a pin, the handle 4033 and the shifting block 4035 are connected as a whole by an axis, the axis is rotatably connected to the connecting piece 1 4031, the shifting block 4035 is connected to the pin with a spring 4036, and the shifting block 4035 is connected to the pin with a spring 4036. Block 4035 is limited in the limiting groove of the middle block 4034, and the second connecting piece 4032 is engaged with the middle block 4034 through the shift fork; when the backrest 401 is in the working state, the middle block 4034 is engaged with the second connecting piece 4032, the spring 4036 is in a free state, and the backrest 401 is locked. When the handle 4033 is pressed down and the backrest 401 is pressed down at the same time, the spring 4036 is stretched, and the shift block 4035 rotates clockwise, driving the middle block 4034 to rotate counterclockwise around the rotation axis through the limiting groove, the middle block 4034 is disengaged from the second connecting piece 4032, the backrest 401 is unlocked, and the backrest 401 can rotate around the rotation axis.

[0044] From the above specific implementations, it can be seen that the utility model has the following beneficial effects:

[0045] 1. By arranging the deformable middle seat 4 between the berth block 1 2 and the berth block 2 1 , the middle seat 4 and the berth can be converted into each other according to the required functions, avoiding the two being independently arranged and occupying a large space;
