[0004] The technical problem this utility model aims to solve is that, in reality, passenger cars, freight cars, and special vehicles are all motor vehicles. When freight cars are used in mountainous areas and under harsh working conditions, there is a lot of dust in these environments. The driver's cab of a freight car is usually ventilated by opening windows. When the windows are opened for ventilation, dust will enter the driver's cab, thereby affecting the driver's operation and causing certain hazards.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a high-strength lightweight motor vehicle cab, including a cab body. The inner wall of the cab body is provided with a ventilation device. When the truck is used in mountainous areas or harsh working conditions, after the windows are closed, the external air is drawn into the interior through the air inlet on the air guide cover by the fan blades, and then blown into the interior of the cab body through the nozzle frame. The air inside the cab body is then discharged through the ventilation holes and the first filter screen to achieve the effect of ventilation and air exchange, thereby preventing external dust from entering the interior of the cab body.
[0006] Preferably, the ventilation device includes two first filters, ventilation holes are provided on both sides of the inner wall of the cab body, and the first filters are fixedly installed in the inner wall of the ventilation holes; an air guide hood, wherein one side of the air guide hood is fixedly installed on one side of the cab body, and the inner wall of the air guide hood has several ventilation holes, the ventilation holes are small in size and have a ventilation and filtration effect; two air guide pipes, wherein the two ends of the air guide pipes are respectively installed through one end of the outer surface of the air guide hood and one side of the cab body and extend into the inner wall of the cab body; a nozzle bracket, wherein one end of the nozzle bracket is installed through one end of the outer surface of the two air guide pipes; a bracket, wherein the two ends of the bracket are respectively fixedly installed on the outer surface of the air guide hood; a motor, wherein one side of the motor is fixedly installed on one side of the bracket; and a fan blade, wherein one end of the fan blade is installed through one side of the inner wall of the air guide hood and is fixedly installed on the output end of the motor by means of a coupling.
[0007] The aforementioned components achieve the following effect: By installing a ventilation device, when the truck is used in mountainous areas or harsh working conditions, the windows on the main body of the cab can be closed. Then, the motor on the bracket is started to drive the fan blades to rotate inside the air guide shroud. External air is filtered through the ventilation holes on the air guide shroud and then drawn into the interior of the air guide shroud. It is then delivered into the air guide pipe and finally blown into the interior of the main body of the cab through the nozzle frame. The air inside the main body of the cab is then compressed and exchanged before being discharged from the ventilation holes. The first filter installed in the ventilation holes will block external dust, thus allowing for ventilation and replacement of the air inside the main body of the cab. This allows the main body of the cab to effectively filter dust during ventilation, preventing dust from entering the main body of the cab and ensuring a good working environment for the driver to avoid harm.
[0008] Preferably, a bearing is fixedly installed on the outer surface of one end of the fan blade, and the outer ring of the bearing is fixedly installed on one side of the air guide cover.

[0032] Figure 1-6The high-strength lightweight vehicle cab shown includes a cab body 1. The inner wall of the cab body 1 is equipped with a ventilation device 2. When the truck is used in mountainous areas or harsh working conditions, the ventilation device 2 allows the outside air to enter the cab body 1 through the air inlet on the air guide 23 after the windows are closed by the fan blades 28. Then, the air is blown into the cab body 1 through the nozzle frame 25, so that the air inside the cab body 1 is discharged through the ventilation holes 21 and the first filter screen 22 to achieve the effect of ventilation and air exchange, thereby preventing external dust from entering the cab body 1.
[0033] Figure 2-4The ventilation device 2 shown includes two first filters 22, ventilation holes 21 are provided on both sides of the inner wall of the cab body 1, and the first filters 22 are fixedly installed in the inner wall of the ventilation holes 21; a wind guide hood 23, one side of which is fixedly installed on one side of the cab body 1, and the inner wall of which is provided with several ventilation holes 21. The ventilation holes 21 are small in size and have a ventilation and filtration effect; two air guide pipes 24, the two ends of which are respectively installed through one end of the outer surface of the wind guide hood 23 and one side of the cab body 1 and extend into the inner wall of the cab body 1; a nozzle bracket 25, one end of which is installed through one end of the outer surface of the two air guide pipes 24; a bracket 26, the two ends of which are respectively fixedly installed on the outer surface of the wind guide hood 23; a motor 27, one side of which is fixedly installed on one side of the bracket 26; and a fan blade 28, one end of which is installed through one side of the inner wall of the wind guide hood 23 and fixedly installed on the output end of the motor 27 by means of a coupling. When the truck is used in mountainous areas or harsh working conditions, the windows on the cab body 1 can be closed. Then, the motor 27 on the bracket 26 is started, driving the fan blades 28 to rotate inside the air guide shroud 23. External air is drawn into the air guide shroud 23 after being filtered through the ventilation holes 21, then transported into the air guide pipe 24, and finally blown into the cab body 1 through the nozzle frame 25. The air inside the cab body 1 is then compressed and exchanged before being discharged through the ventilation holes 21. The first filter 22 installed in the ventilation holes 21 blocks external dust, thus ventilating and replacing the air inside the cab body 1. This allows the cab body 1 to effectively filter dust during ventilation, preventing dust from entering the cab body 1 and ensuring a good working environment for the driver, avoiding potential hazards. A bearing 210 is fixedly installed on the outer surface of one end of the fan blade 28, and the outer ring of the bearing 210 is fixedly installed on one side of the air guide shroud 23. By incorporating bearing 210, rotational wear between fan blade 28 and air guide shroud 23 can be reduced, facilitating fan blade 28 rotation and extending service life. The ventilation device 2 also includes several second filters 211, the outer surfaces of which are fixedly installed on the inner walls of several outlets of the nozzle frame 25. By using the second filters 211, the gas ejected from the nozzle frame 25 can undergo secondary filtration, ensuring that the air entering the cab body 1 is dust-free and improving ventilation quality.
[0034] Figure 2-4The ventilation device 2 shown also includes a cleaning mechanism 29, which includes a brush 291. One end of the brush 291 is fixedly mounted on the outer surface of one end of the fan blade 28, and one end of the bristles is in close contact with the outer surface of the air inlet of the air guide shroud 23. A limiting groove 292 is formed on one side of the air guide shroud 23; a limiting block 293 is slidably mounted in the inner wall of the limiting groove 292. By setting the cleaning mechanism 29, when the fan blade 28 rotates, it will drive the brush 291 and the limiting block 293 to rotate at the air inlet and the limiting groove 292 on the air guide shroud 23, respectively, brushing off the dust attached to the air inlet and preventing the dust from stagnating at the air inlet and causing blockage. The brush 291 can brush it.
[0035] Figure 5 and Figure 6 A protective device 3 is installed on one side of the cab body 1 above the air guide hood 23. The protective device 3 includes two recessed blocks 31 and a protective cover 33. One side of the two recessed blocks 31 is fixedly installed on one side of the cab body 1. Threaded holes 32 are opened on both sides of the inner wall of the recessed blocks 31. Two screw rods 34 are provided, with one end of the screw rod 34 fixedly installed on one side of the protective cover 33 and the other end inserted into the inner wall of the recessed block 31. Two bolts 35 are provided, with one end of the bolts 35 screwed into the threaded holes 32 and the inner wall of the screw rods 34. By setting up the protective device 3, the protective cover 33 can be inserted into the inner wall of the recessed block 31 with the help of the screw rods 34. Then, the bolts 35 are screwed into the threaded holes 32 and the inner wall of the screw rods 34, fixing and limiting the protective cover 33 above the air guide hood 23, thus protecting it. This prevents damage to the air guide hood 23 and motor 27 in the event of falling rocks during operation in deep pit terrain, thereby improving the service life of the ventilation device 2.
[0036] Figure 5 and Figure 6 The longitudinal section of the screw rod 34 shown is trapezoidal at one end, and the dimension of the end of the screw rod 34 away from the protective cover 33 is smaller than the dimension of the other end. By setting the screw rod 34 to a trapezoidal shape, the area at one end can be reduced, making it easier to quickly align with the groove block 31 and insert it, thus facilitating installation. The protective device 3 also includes a reinforcing rod 36, wherein the two ends of the reinforcing rod 36 are respectively fixedly installed on one side of the protective cover 33 and the screw rod 34. By setting the reinforcing rod 36, the connection area between the screw rod 34 and the protective cover 33 can be increased, making the connection more secure and stable.
[0037] Working principle: When the truck is used in mountainous areas or harsh working conditions, the windows on the cab body 1 can be closed. Then, the motor 27 on the bracket 26 is started to drive the fan blades 28 to rotate inside the air guide shroud 23. The outside air is filtered through the ventilation holes 21 on the air guide shroud 23 and then drawn into the interior of the air guide shroud 23. It is then delivered into the air guide pipe 24 and finally blown into the interior of the nozzle frame 25. The air inside the cab body 1 is then compressed and exchanged and discharged from the ventilation holes 21. The first filter 22 installed in the ventilation holes 21 will block the outside dust. Therefore, the air inside the cab body 1 can be ventilated and replaced. This allows the cab body 1 to effectively filter dust during the ventilation process, preventing dust from entering the cab body 1 and ensuring a good working environment for the driver to avoid harm. When the fan blade 28 rotates, it will drive the brush 291 and the limiting block 293 to rotate at the air inlet and the limiting groove 292 on the air guide cover 23, respectively, to brush off the dust attached to the air inlet and prevent the dust from stagnating at the air inlet and causing blockage. The brush 291 can brush it.
[0038] Before using the ventilation device 2, the protective cover 33 can be inserted into the inner wall of the groove block 31 using the screw rod 34. Then, the bolt 35 is screwed into the inner wall of the threaded hole 32 and the screw rod 34 to fix the protective cover 33 above the air guide cover 23 for protection. This will prevent damage to the air guide cover 23 and the motor 27 in the event of falling rocks when working in deep pit terrain, thus improving the service life of the ventilation device 2.
[0039] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
