DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present application and its application or use. Example 1

[0019] like Figure 1-Figure 2 As shown, this embodiment provides a descendable cab, comprising an outer bottom plate 3, an inner bottom plate 4 and a connecting component, wherein the outer bottom plate 3 is arranged at the bottom of the cab shell 2, a driving device is installed on the inner bottom plate 4, and the outer bottom plate 3 is connected to the inner bottom plate 4 through the connecting component, and the connecting component comprises a Z-shaped mounting plate 11 and a fixing plate 10; When the cab is transported, the outer bottom plate 3 and the inner bottom plate 4 are connected by the Z-shaped mounting plate 11 to reduce the height of the cab shell 2. When the cab is used for driving, the outer bottom plate 3 and the inner bottom plate 4 are connected by the fixing plate 10.

[0020] Since there needs to be space in the cab to accommodate the driver, the cab shell 2 is relatively high. Therefore, this embodiment can meet the height of the container when the cab is transported, and during the transportation of the cab, no space is needed in the cab to accommodate the driver. The inner bottom plate 4 and the outer bottom plate 3 can be connected by a Z-shaped mounting plate 11. At this time, the outer bottom plate 3 is located below the inner bottom plate 4, and the height of the cab shell 2 is reduced, thereby reducing the height of the entire cab. Example 2

[0021] This embodiment provides a lowerable cab based on the first embodiment, and the difference from the first embodiment is that: like Figure 2 , Figure 4As shown, there are four Z-shaped mounting plates 11, which are arranged on both sides of the inner bottom plate 4 and connected to both sides of the outer bottom plate 3. The upper and lower ends of the Z-shaped mounting plates 11 are respectively connected to the inner bottom plate 4 and the outer bottom plate 3, and the outer bottom plate 3 is installed at the lower end, so that the outer bottom plate 3 and the cab shell 2 can be installed on the inner bottom plate 4, and the height of the cab shell 2 on the outer bottom plate 3 can be lowered.

[0022] The Z-shaped mounting plate 11 includes a first plate, a second plate and an intermediate plate connecting the first plate and the second plate, the inner bottom plate 4 is connected to the first plate, and the outer bottom plate 3 is connected to the second plate.

[0023] In this embodiment, the first plate is located above the second plate, and the first plate and the second plate are parallel to each other, so that the outer bottom plate 3 is located below the inner bottom plate 4. A plurality of mounting holes are provided on the first plate and the second plate, and the bolt assembly cooperates with the mounting holes to realize the installation of the Z-shaped mounting plate 11, the inner bottom plate 4 and the outer bottom plate 3. Without changing the installation position and relationship of the inner bottom plate 4, the outer bottom plate 3 is connected to the second plate to realize the reduction of the height of the cab shell 2, thereby realizing the reduction of the height of the entire cab.

[0024] The lowerable cab provided in the present embodiment has an inner bottom plate 4 for installing the driving equipment in the cab and an outer bottom plate 3 for installing the cab shell 2 separately arranged. During transportation, there is no need to disassemble the entire cab from the vehicle body 1 for transportation. It is only necessary to disassemble the outer bottom plate 3 with the cab shell 2 from the inner bottom plate 4, and then connect the inner bottom plate 4 with the outer bottom plate 3 using a Z-shaped mounting plate 11, thereby lowering the overall height of the cab. The cab can be installed on the vehicle body 1 for transportation without separate loading and transportation, which reduces management during transportation and facilitates disassembly during loading and unloading. The used Z-shaped mounting plate 11 has a simple structure and low cost.

[0025] like Figure 1 , Figure 3 , Figure 4 As shown, when the cab is used for driving, the Z-shaped mounting plate 11 is replaced with the fixing plate 10, and the inner bottom plate 4 and the outer bottom plate 3 are installed together. At this time, the inner bottom plate 4 and the outer bottom plate 3 are located at the same horizontal height, the height of the cab shell 2 is restored to its original height, and the internal space is accessible to the driver.

[0026] In some embodiments, the driving device includes an instrument box 14, a seat 15, a handbrake 17 and a control box 16. The seat 15 is arranged in the middle of the inner bottom plate 4, the instrument box 14 is arranged in front of the seat 15, and a steering wheel is arranged on the instrument box 14. A handbrake is arranged on one side of the seat 15, and a control box 16 is arranged on the other side.

[0027] A rear cover plate 7 is also provided on the inner bottom plate 4, and the rear cover plate 7 is arranged behind the seat. A number of bolt holes are provided on the rear cover plate 7 and the cab shell 2. The rear cover plate 7 is connected to the cab shell 2 through the combination of the bolt holes and the bolts to strengthen the connection between the inner bottom plate 4 and the cab shell 2. When disassembling the outer bottom plate 3, the rear cover plate 7 is removed and replaced with a Z-shaped mounting plate 11. The rear cover plate 7 is then installed in combination with the bolt holes at a higher position on the cab shell 2 to achieve stable installation of the cab shell 2 and avoid collision between the cab shell 2 and other components during transportation.

[0028] A rubber floor 8 is laid on the upper surface of the inner bottom plate 4 . The rubber floor 8 is mounted on the inner bottom plate 4 by bolts. Holes for mounting driving equipment on the inner bottom plate 4 are opened on the rubber floor 8 .

[0029] A control panel support plate 12 is provided at the bottom of the inner bottom plate 4, and shock absorbers 5 are installed at both ends of the control panel support plate 12. The shock absorber 5 is connected to the shock absorbing block 6, and the shock absorbing block 6 is provided with a countersunk hole. The shock absorber 5 is installed at the bottom of the inner bottom plate 4 through the countersunk hole and the dome plug 13, wherein the dome plug 13 is inserted into the countersunk hole from the opening on the surface of the inner bottom plate 4.

[0030] An adjustment washer 9 is also provided between the shock absorber 5 and the shock absorbing block 6. The shock absorber 5, the adjustment washer 9 and the shock absorbing block 6 are stacked in sequence from bottom to top and connected together by bolts. The shock absorber 5 is connected to the inner bottom plate 4 through the shock absorbing block 6, and the shock absorber 5 is connected to the console support plate 12, which plays a role in shock absorption and support for the driving equipment on the inner bottom plate 4.

[0031] There are two control panel support plates 12, which are respectively arranged on both sides of the bottom plate. The control panel support plates 12 are installed on the vehicle body 1, so that the cab can be installed on the vehicle body 1 for use.

[0032] During transportation, the cab shell 2 and the outer bottom plate 3 are connected together, the fixing plate 10 between the outer bottom plate 3 and the inner bottom plate 4 is removed, the rear cover plate 7 is removed from the inner wall of the cab shell 2, and the connection between the inner bottom plate 4 and the outer bottom plate 3 is replaced with a Z-shaped mounting plate 11. The position of the inner bottom plate 4 on the vehicle body 1 remains unchanged and is connected to the first plate of the Z-shaped mounting plate 11. The height of the outer bottom plate 3 and the cab shell 2 is lowered and connected to the second plate of the Z-shaped mounting plate 11. The rear cover plate 7 is reconnected with the bolt holes at the high position of the cab shell 2 to prevent the cab from shaking. The height of the entire cab is lowered to adapt to the height of the container during transportation. The cab does not need to be removed from the vehicle body. It only needs to remove the cab shell 2 and replace the connecting parts to achieve the reduction of the cab height. After transporting to the destination, the Z-shaped mounting plate 11 is replaced with the fixed plate 10, the inner bottom plate 4 and the outer bottom plate 3 are located at the same horizontal plane, and the cab shell 2 is restored to the height of the original use state.
