Description

Technical Field

[0001] This utility model relates to the field of tractors, specifically to a cab column that also functions as an air conditioning duct. Background Technology

[0002] Traditional tractor cabs have two spaced-apart pillars at the front, with the windshield installed between them. The tractor's air conditioning system is mounted on the roof of the cab, supplying cooling air into the cab through a top duct. Additionally, an interior air duct connected to the top duct needs to be installed within the cab. Since the interior air duct is usually independent of the vehicle structure, it requires extra space, resulting in a complex cab layout and low space utilization. The area around the front pillars, in particular, is often used only as a supporting structure, failing to fully utilize its internal or side space, leading to a single structural function.

[0003] Currently, air conditioning ducts typically use independent plastic or metal pipes that extend along the cab ceiling, dashboard, or side walls to guide airflow to different vents. Existing independent ducts require additional installation, encroaching on the limited space of the cab and affecting interior aesthetics and passenger comfort. Long-distance ducts can lead to airflow pressure loss, affecting air delivery efficiency, especially causing slower response times when defrosting the windshield. Independent ducts also require separate mounting, increasing assembly difficulty and potentially requiring the disassembly of multiple components for maintenance, resulting in higher costs. These issues warrant improvement. Utility Model Content

[0004] The purpose of this utility model is to provide a cab column that optimizes space utilization, improves airflow efficiency, and ensures convenient installation and maintenance, while also functioning as an air conditioning duct, to address the above problems.

[0005] To achieve the above objectives, this utility model discloses a cab pillar that also functions as an air conditioning duct. The pillar is characterized by the following features: a decorative sleeve is installed on the side of the pillar, the decorative sleeve includes a partition, and connecting plates are provided on both the left and right sides of the partition. The two connecting plates are respectively connected to two opposite sides of the pillar. The partition and the pillar are spaced apart from each other, and an air duct for airflow is provided between the partition and the pillar. An air inlet sleeve is provided on the top of the decorative sleeve, and a first air outlet facing the windshield is provided on the air inlet sleeve.

[0006] Integrating the air conditioning column duct with the cab column saves space, reduces the need for additional duct installation, and improves the compactness of the cab layout. A concealed air duct is formed by a partition between the duct and the column. This avoids exposed ducts affecting aesthetics and utilizes the side space of the column for efficient airflow guidance. The air intake sleeve connects to the roof duct and guides airflow to the windshield area. This allows for rapid defogging and defrosting, improves driver visibility, and concentrates airflow to enhance air conditioning efficiency.

[0007] A base plate is installed in the air duct and is fixedly mounted on the column. The base plate and the partition are spaced apart from each other, and the connecting plate is attached to the left and right sides of the base plate. The partition and the connecting plate are integrally formed, and the base plate, partition, and connecting plate together form an air duct for airflow.

[0008] The air inlet sleeve connects to the top air duct, and the upper part of the air inlet sleeve has an air inlet that communicates with the top air duct. Ensuring a precise alignment between the top air duct and the internal air duct of the decorative sleeve can reduce airflow leakage, maintain stable air pressure, and improve air delivery efficiency.

[0009] The decorative cover has a second and a third air outlet connected to the air duct, which are spaced vertically apart. The vertical distribution of the second and third air outlets creates layered air supply, meeting the air supply needs at different heights and enhancing comfort.

[0010] Both the second and third air vents face the driver's seat. Directly directing the air vents towards the driver ensures precise airflow, reduces airflow waste, and improves driver comfort.

[0011] The trim sleeve has a recessed groove to avoid interference with the door lock installation space, ensuring the door can open and close normally.

[0012] The lower end of the partition is equipped with a sealing plate that closes the lower opening of the decorative sleeve. The lower part of the sealing plate rests against the column. The sealing plate closes the lower end of the decorative sleeve and fits against the column to prevent airflow leakage, while also enhancing the overall structural integrity and preventing foreign objects from entering the air duct.

[0013] The decorative sleeve extends along the height of the column, and its shape matches the shape of the column. The decorative sleeve fits the shape of the column to ensure the airtightness of the air duct.

[0014] There are two support columns, located on the left and right sides of the front of the cab. The air ducts are symmetrically arranged on the left and right columns, which can balance the air supply coverage of the cab and can work independently to meet the different needs of the left and right sides.

[0015] The connecting plate has through holes for mounting bolts. The bolts pass through the through holes and are threaded onto the column. There are multiple through holes, spaced vertically. This design ensures a secure and removable installation, facilitating maintenance or replacement of the decorative sleeve components. It also distributes stress, preventing deformation or loosening of the decorative sleeve and enhancing long-term stability.

[0016] In summary, the beneficial effects of this utility model are as follows: It utilizes the redundant space of the pillars to install air ducts, freeing up cab space, reducing the need for additional air duct installations, and improving the compactness of the cab layout. A concealed air duct is formed by the partition and the pillars, avoiding the aesthetic impact of exposed air ducts, while simultaneously utilizing the side space of the pillars to achieve efficient airflow guidance. The air inlet sleeve connects to the top air duct and guides airflow to the windshield area. This allows for rapid defogging and defrosting, improves driver visibility, and concentrates airflow to enhance air conditioning efficiency. Attached Figure Description
