[0034] It should be noted that the corresponding space is provided at the rear of the light truck cab, which is usually used by the driver for daily rest or storage, and the cab bunk device provided in the application is provided according to the space at the rear of the cab to create good resting conditions for the driver. For the installation of the cab bunk device, bolts can be sequentially threaded through the support foot 3 and the inner wall of the cab for screwing. In some optional embodiments of the application, the support foot 3 can be fixedly connected with the fixing frame 1 or the fixing frame 1 is overlapped on the support foot 3, so that the driver can select to disassemble the fixing frame 1 according to the need, and then the driver can lay the soft pad 2 adapted to the fixing frame 1 on the top of the fixing frame 1, and install the shielding assembly 6 on the side of the fixing frame 1, and finally combine to form the cab bunk device. In order to reduce the weight of the vehicle, the fixing frame 1 can be made of hollow aluminum alloy steel with high strength and light weight, which can reduce the weight of the vehicle while ensuring the overall structural strength of the cab bunk device.

[0035] In specific implementation, when the driver finishes resting, the fixed sleeve 606 can be pulled to move away from the winding assembly, and the friction rod 605 and the sleeve shell 604 are driven by the fixed sleeve 606 to slide along the track of the rack 301 away from the winding assembly, so that the sleeve shell 604 pulls the shielding film 603, the shielding film 603 wound on the elastic rotating rod 602 is pulled away from the winding assembly, and the elastic rotating rod 602 is rotated to release the shielding film 603. When the elastic rotating rod 602 rotates, the clockwork spring at the connection between the elastic rotating rod 602 and the fixed sheet 601 is tightened and stored. At the same time, when the fixed sleeve 606 moves away from the winding assembly, the support column 607, the sliding block 609 and the first magnet 610 are sequentially driven to move. After the sliding block 609 moves to the side of the moving groove 4 and the rack 301 away from the winding assembly, the first magnet 610 and the second magnet 611 are attracted together to limit and fix the sliding block 609 away from the winding assembly, so that the quilt on the top of the shielding film 603 and the soft pad 2 is covered, reducing the pollution of dust to the quilt, and ensuring the cleanliness of the resting environment of the driver.

[0036] Further, after the fixed sleeve 606 moves away from the winding assembly to drive the shielding film 603 to cover the quilt, the driver can press down the fixed sleeve 606 to drive the limiting hook 401 arranged on the inner side thereof to move towards the first baffle 402, so that the elastic sheet 405 is elastically deformed between the fixed sleeve 606 and the support column 607. At the same time, the lower end of the limiting hook 401 is first deflected backward through the first baffle 402, and then is clamped on the lower side of the first baffle 402, so that the fixed sleeve 606 drives the friction rod 605 to move downward and is limited, and then the fixed sleeve 606 drives the shielding film 603 to move towards the soft pad 2, so that the shielding film 603 is more closely attached to the soft pad 2, to further improve the dustproof effect.

[0037] Then, when the driver needs to rest, just press the fixed sleeve 606 again, the lower end of the limiting hook 401 slides along the upper surface of the front side of the second stopper 403 to the front side of the third stopper 404, and then the fixed sleeve 606 is reset due to the elastic force of the elastic sheet 405, so that the fixed sleeve 606 is pushed to the side close to the rolling assembly, so that the first magnet 610 and the second magnet 611 are separated, then the spring in the connecting part of the elastic rotating rod 602 and the fixed sheet 601 drives the elastic rotating rod 602 to rotate, so that the elastic rotating rod 602 winds the shielding film 603, and then resets the friction rod 605 and the sleeve 604, and at the same time that the elastic rotating rod 602 winds the shielding film 603, the elastic rotating rod 602 drives the transmission rod 201 to rotate through the transmission belt 202, and then the transmission rod 201 drives the brush 203 to clean the outer wall of the shielding film 603, so that the dust on the surface of the shielding film 603 is swept off, thereby avoiding pollution in subsequent use, and the brush 203 on the surface of the shielding film 603 is deformed when passing through the baffle 204 abutting thereto during rotation, so that the dust adhered to the brush 203 is shaken off into the collecting box 205, and the collecting box 205 can be pulled out for cleaning when cleaning is needed.

[0038] Subsequently, the first bevel gear 302 moves with the fixed sleeve 606, and since the outer wall of the first bevel gear 302 is engaged with the outer wall of the rack 301, the first bevel gear 302 rotates, thereby driving the second bevel gear 303 and the fixed shaft 304 to rotate, and the fixed shaft 304 drives the friction rod 605 to rotate through the transmission belt 305, and since the sleeve 604 cannot rotate due to being pulled by the shielding film 603, the friction rod 605 rubs against the sleeve 604, so that the sleeve 604 generates static electricity, and during the movement of the sleeve 604, the mattress is continuously adsorbed, so that the dust on the surface of the mattress is removed, and after the sleeve 604 is reset, the dust can be removed by wiping the surface of the sleeve 604 with a wet wipe, and after the supporting column 607 is reset, the pressing block 505 is pressed, so that the pressing block 505 moves to the inside of the liquid box 501 to compress the spring 507, and at the same time that the pressing block 505 moves to the inside of the liquid box 501, the air pressure in the liquid box 501 increases, so that the liquid in the liquid box 501 is discharged to the upper side of the collecting box 205 through the drain pipe 506, and then the liquid is atomized by the atomizing nozzle at the upper end of the drain pipe 506, so that the dust collected on the upper side of the collecting box 205 is humidified to prevent the dust from being scattered outward, and since the evaporation speed of the atomized water is accelerated, the humidity on the left side of the driver's cabin and the fixed frame 1 is slightly increased, thereby avoiding that the mattress generates a large amount of static electricity to adsorb dust, and reducing the deposition of pollutants on the mattress.

[0039] In summary, by setting the fixed frame 1, the soft pad 2, the supporting leg 3 and other structures, the soft pad 2 is stably supported, so that the driver can rest stably, by setting the shielding assembly 6, the shielding film 603 wound on the winding assembly can be unfolded to the other side and cover the top of the soft pad 2, thereby avoiding the contamination of the top of the soft pad 2, by setting the winding assembly, the device can clean the dust deposited on the upper surface of the shielding film 603 when winding the shielding film 603, so that it can be self-cleaning every time it is used, avoiding contamination of the mattress, by setting the adsorption assembly 613, the device can remove the pollutants on the surface of the mattress when in use, avoiding the growth of bacteria caused by the large amount of pollutants deposited on the surface of the mattress, creating a good resting environment for the driver and ensuring the cleanliness of the resting environment, solving the problem that the current bed structure is single and has no protective structure, and the amount of dust in the vehicle working environment is large, thereby contaminating the driver's bed and affecting the driver's driving experience and resting quality.
