Description

Technical Field

[0001] This utility model relates to the field of cab assembly technology, specifically to an environmentally friendly ventilation device for automobile cab assemblies. Background Technology

[0002] A cab assembly is an assembled form of a cab, generally used in the commercial vehicle sector. It refers to a cab configuration where the cab can be mounted on the chassis, allowing the vehicle to be driven directly after installation. Currently, existing cab assemblies typically involve opening the main windows for ventilation, which allows many impurities from the outside air to enter the cab. Over time, these impurities accumulate, affecting the cleanliness of the cab, making cleaning difficult, and negatively impacting both normal driving and the driver's health.

[0003] In the prior art, as shown in the authorized announcement number "CN215474345U", an environmentally friendly ventilation device for automobile cab assembly utilizes the cooperation between the return plate, baffle and filter to reduce the possibility of impurities in the outside air entering the cab, thereby reducing the accumulation of impurities in the cab and affecting the cleanliness of the cab.

[0004] However, existing technologies still have significant shortcomings, such as:

[0005] In the existing technology: Although the device has the function of filtering external air and preventing dust, the ventilator is difficult to disassemble; because the external dust content is high when the car is in motion, the dust accumulated inside the ventilator is easy to adhere to the filter and fan surface when used for a long time. Over time, this will not only significantly reduce the ventilation efficiency, but also easily cause irreversible damage to the fan. Utility Model Content

[0006] The purpose of this utility model is to provide an environmentally friendly ventilation device for automobile cab assembly to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an environmentally friendly ventilation device for an automobile cab assembly, comprising a cab assembly, wherein ventilation mechanisms for ventilation are installed through both sides of the cab assembly;

[0008] The ventilation mechanism includes two internal fixing plates installed on both sides inside the cab assembly. Both sides of the cab assembly are equipped with external mounting housings. Dustproof ventilation components for ventilation are installed inside both the internal fixing plates and the external mounting housings.

[0009] A disassembly / reassembly component is installed between the inner fixing plate and the outer mounting housing for disassembling and assembling the inner fixing plate and the outer mounting housing.

[0010] Preferably, the disassembly component includes two mounting cylinders that are connected and installed on one side of the cab assembly. The surface of the mounting cylinder is provided with external threads. Two internally threaded connecting shells are installed through one side of the inner side of the outer mounting housing. The internally threaded connecting shells are sleeved on the surface of the mounting cylinder and threadedly connected to the mounting cylinder.

[0011] A second filter plate is installed on one side inside the outer mounting housing. Mounting plates are fixedly installed on all four sides inside the second filter plate. Four threaded sleeves are fixedly installed on the side of the inner fixing plate near the outer mounting housing. Bolts are installed through the surface of the four mounting plates. One end of the bolts penetrates the outer mounting housing and is threadedly connected to the threaded sleeve.

[0012] Preferably, the dustproof ventilation component includes a motor disposed inside the mounting cylinder, and fan blades are fixedly installed at the output end of the motor;

[0013] A guide housing is installed between the outer mounting housing and the second filter plate. Air inlets are provided on both sides of the guide housing, and the two air inlets are diagonally opposite each other. A filter for purifying air is installed inside the guide housing.

[0014] Preferably, a bracket is fixedly installed inside the mounting cylinder, and the bracket is sleeved on the surface of the motor and fixedly connected to the motor.

[0015] Preferably, a first filter plate is fixedly installed at the connection between the inner fixing plate and the mounting cylinder to prevent dust from entering the cab assembly.

[0016] Preferably, a sealing gasket is installed on the side of the inner fixing plate and the outer mounting housing that is close to the cab assembly. The sealing gasket has the same size as the inner fixing plate and the outer mounting housing, and the sealing gasket is made of rubber.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. By utilizing the disassembly and assembly components, when a large amount of dust accumulates inside the inner fixed plate and the outer mounting housing, the mounting plate and threaded sleeve can be separated to remove the second filter plate and guide housing. Furthermore, through the threaded connection between the inner threaded connecting shell and the mounting cylinder, the outer mounting housing and the inner fixed plate can be separated to facilitate the disassembly and maintenance of the motor and fan blades inside the mounting cylinder. This allows for the complete disassembly of the ventilation mechanism, preventing dust from accumulating inside the ventilation mechanism for a long time and affecting the ventilation effect.

[0019] 2. When ventilation is required in the cab assembly, the motor drives the fan blades to generate airflow, which draws in external air through the air inlet and the guide housing. At the same time, the second filter plate blocks larger dust particles from the outside. When the air enters the interior of the guide housing, the internal filter further filters the dust in the air. This ensures that the external air is filtered before being discharged into the cab assembly, preventing external dust from entering the cab assembly and affecting its cleanliness.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-5 This utility model provides a technical solution: an environmentally friendly ventilation device for an automobile cab assembly, including a cab assembly 1, with ventilation mechanisms 2 for ventilation installed through both sides of the cab assembly 1;

[0028] The ventilation mechanism 2 includes two inner fixing plates 21 installed on both sides inside the cab assembly 1. Both sides of the cab assembly 1 are equipped with outer mounting housings 22. Dustproof ventilation components 23 for ventilation are installed inside both the inner fixing plates 21 and the outer mounting housings 22.

[0029] A disassembly / reassembly component 24 for disassembling and assembling the inner fixing plate 21 and the outer mounting housing 22 is installed between the inner fixing plate 21 and the outer mounting housing 22.

[0030] Reference Figure 2 , Figure 3 as well as Figure 4 As shown, the disassembly component 24 includes two mounting cylinders 241 connected and installed on one side of the cab assembly 1. The surface of the mounting cylinder 241 is provided with external threads 242. Two internal threaded connecting shells 243 are installed through one side of the inner side of the outer mounting housing 22, and the internal threaded connecting shells 243 are sleeved on the surface of the mounting cylinder 241 and threadedly connected to the mounting cylinder 241. A second filter plate 244 is installed on one side of the inner side of the outer mounting housing 22. Mounting plates 245 are fixedly installed on all four sides of the inner side of the second filter plate 244. Four threaded sleeves 246 are fixedly installed on the side of the inner fixing plate 21 near the outer mounting housing 22, and bolts 247 are installed through the surface of the four mounting plates 245. One end of the bolt 247 passes through the outer mounting housing 22 and is threadedly connected to the threaded sleeve 246.

[0031] In this embodiment, the mounting plate 245 is separated from the threaded sleeve 246 to remove the second filter plate 244 and the guide housing 233. The outer mounting housing 22 can be separated from the inner fixing plate 21 by the threaded connection between the inner threaded connecting shell 243 and the mounting cylinder 241. This allows for the disassembly and maintenance of the motor 231 and fan blade 232 inside the mounting cylinder 241. In this way, the entire ventilation mechanism 2 can be disassembled, preventing dust from accumulating inside the ventilation mechanism 2 for a long time and affecting the ventilation effect of the ventilation mechanism 2.

[0032] Reference Figure 3 as well as Figure 4 As shown, the dustproof ventilation component 23 includes a motor 231 installed inside the mounting cylinder 241, and a fan blade 232 is fixedly installed at the output end of the motor 231; a guide housing 233 is installed between the outer mounting housing 22 and the second filter plate 244, and air inlets 234 are opened on both sides of the guide housing 233, and the two air inlets 234 are diagonally opened; a filter for purifying air is installed inside the guide housing 233.

[0033] In this embodiment, the motor 231 drives the fan blades 232 to generate wind power, and draws in external air through the air inlet 234 and the guide housing 233. At the same time, the second filter plate 244 blocks larger dust particles from the outside. When the air enters the interior of the guide housing 233, the filter inside filters the dust in the air again. In this way, the external air is filtered and discharged into the interior of the cab assembly 1, preventing external dust from entering the interior of the cab assembly 1 and affecting its cleanliness.

[0034] Reference Figure 3 as well as Figure 5 As shown, a bracket 235 is fixedly installed inside the mounting cylinder 241, and the bracket 235 is sleeved on the surface of the motor 231 and fixedly connected to the motor 231.

[0035] In this embodiment, the motor 231 can be supported and installed to prevent the motor 231 and the fan blade 232 from shaking during operation, which would affect ventilation.

[0036] Reference Figure 3 As shown, a first filter plate 236 is fixedly installed at the connection between the inner fixing plate 21 and the mounting cylinder 241 to further prevent dust from entering the cab assembly 1.

[0037] Reference Figure 2 As shown, sealing gaskets 25 are installed on the side of the inner fixing plate 21 and the outer mounting housing 22 that are close to the cab assembly 1. The size of the sealing gasket 25 is the same as that of the inner fixing plate 21 and the outer mounting housing 22, and the material of the sealing gasket 25 is a rubber component.

[0038] In this embodiment, the connection between the inner fixing plate 21, the outer mounting housing 22 and the cab assembly 1 can be sealed to prevent rainwater from entering the interior of the cab assembly 1 during rainy weather.

[0039] Working principle: During the ventilation process of the cab assembly 1, the motor 231 drives the fan blade 232 to generate wind power, and draws in external air through the air inlet 234 and the guide housing 233. At the same time, the second filter plate 244 blocks larger dust particles from the outside. When the air enters the interior of the guide housing 233, the filter inside filters the dust in the air again, and then blows the air into the interior of the cab assembly 1 for ventilation.

[0040] Furthermore, when a large amount of dust accumulates inside the inner fixing plate 21 and the outer mounting housing 22, the mounting plate 245 and the threaded sleeve 246 can be separated to remove the second filter plate 244 and the guide housing 233. The outer mounting housing 22 can be separated from the inner fixing plate 21 through the threaded connection between the inner threaded connecting shell 243 and the mounting cylinder 241, so that the motor 231 and the fan blade 232 inside the mounting cylinder 241 can be disassembled and maintained.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
