Description

Technical Field

[0001] This invention relates to the field of vehicle passenger compartment air duct technology, specifically to a dedicated air duct for vehicle air conditioning and a vehicle. Background Technology

[0002] For large passenger vehicles, such as buses, Figure 1 As shown, the air conditioner 1 is generally located on the roof, and the air treated by the air conditioning is delivered into the vehicle through air conditioning ducts 2 set on the left and right sides of the roof. To maximize the interior space and meet the width and height standards for buses, some vehicle components are placed within the air conditioning ducts during the overall vehicle design, such as... Figure 2 and Figure 3 As shown, since air conditioners or batteries are installed on the roof of the bus, diagonal braces 4 are added between the roof and the side frame to increase the roof strength. Generally, there are multiple reinforcing diagonal braces, which are spaced apart in the air conditioning duct extension direction. In addition, speakers 5, air tanks 6, and wiring harnesses 7 of corresponding electrical components are also installed in the air conditioning duct 2. When the air conditioner 1 delivers air, it enters the left and right air conditioning ducts 2 from the left air conditioning outlet 33 and the right air conditioning outlet 31 on the roof, respectively. After passing through the air conditioning duct, it enters the passenger compartment from the air supply outlet on the side wall 21 of the air conditioning duct facing the passenger compartment, and then returns to the air conditioner from the left air conditioning return outlet 34 and the right air conditioning return outlet 32 ​​on the roof, which are connected to the passenger compartment space.

[0003] However, due to the various components arranged inside the air conditioning duct, the airflow is obstructed by these components as it flows through the duct. This reduces the airflow velocity as the air passes through these components, resulting in lower airflow velocity at the air outlets where these components are located. Consequently, the uniformity of airflow cannot be met, and the air conditioning system cannot deliver the treated air relatively evenly from each outlet to the vehicle interior. This leads to uneven air conditioning throughout the cabin, affecting passenger comfort and increasing the power consumption of the air conditioning system. Summary of the Invention

[0004] The purpose of this invention is to provide a dedicated air duct for automotive air conditioning to solve the problem of uneven airflow from various air outlets in current air conditioning ducts; the purpose of this invention is also to provide a vehicle to solve the above-mentioned problems.

[0005] The technical solution of the vehicle air conditioning duct of the present invention is as follows:

[0006] A dedicated air duct for vehicle air conditioning is disclosed. The dedicated air duct is a flexible body designed for installation within an air conditioning supply duct. The dedicated air duct has a dedicated air inlet and a dedicated air outlet. The dedicated air inlet is connected to an air conditioning outlet on the inner wall of the air conditioning supply duct, and the dedicated air outlet is connected to an air supply duct outlet on the inner wall of the air conditioning supply duct, so that air treated by the air conditioning system can be delivered to the vehicle compartment through the dedicated air duct.

[0007] Beneficial effects: Based on the existing air conditioning duct, a flexible dedicated air duct is set up inside it, so that the air treated by the air conditioning can directly enter the dedicated air duct from the air conditioning outlet through the dedicated air inlet, flow in the dedicated air duct, and then be delivered to the passenger compartment from the air conditioning duct outlet through the dedicated air outlet. Using a flexible dedicated air duct for air delivery can adapt to the space inside the air conditioning duct, reduce abrupt changes in cross-sectional area, avoid the influence of existing air conditioning duct components on airflow, effectively reduce the reduction of airflow kinetic energy due to airflow contact with components, and help ensure the uniformity of airflow from each air outlet.

[0008] Furthermore, the dedicated air duct has a main section that extends along the air conditioning supply duct, and the cross-sectional area of ​​the main section gradually decreases along the airflow direction.

[0009] Beneficial effects: By using a dedicated air duct that is relatively independent from the original air conditioning air supply duct, the cross-section of the air flow channel can be designed separately, so that the cross-sectional area of ​​the main part of the dedicated air duct gradually decreases along the airflow direction. That is, the cross-sectional area is large near the air conditioning end and small far from the air conditioning end. Adjusting the flow velocity helps to improve the uniformity of air outlets in various air supply ducts.

[0010] Furthermore, the dedicated air duct is provided with an adhesive part for bonding to the inner wall of the air conditioning supply duct.

[0011] Beneficial effects: It makes it easy to fix the flexible special air duct to the air conditioning supply duct, preventing the special air duct from drifting with the wind.

[0012] Furthermore, the adhesive part is a hook-and-loop surface or a hook-and-loop hook surface.

[0013] Beneficial effects: The use of Velcro allows the special air duct to be fixed inside the air conditioning supply duct, making it easy to install and remove, and convenient for maintenance.

[0014] Furthermore, the dedicated air outlets on the dedicated air duct are arranged in at least two rows along the vertical direction, with multiple dedicated air outlets in each row and spaced apart from each other.

[0015] Beneficial effects: Increases the number of air outlets and improves air delivery capacity.

[0016] Furthermore, the dedicated air outlets on the dedicated air duct are arranged in three rows: upper, middle, and lower. The upper row of dedicated air outlets is used to connect with the normally open air outlets of the upper air supply duct of the air conditioning duct, the middle row of dedicated air outlets is used to connect with the adjustable air outlets of the middle air supply duct of the air conditioning duct, and the lower row of dedicated air outlets is used to connect with the normally open air outlets of the lower air supply duct of the air conditioning duct.

[0017] Beneficial effects: It makes it easy to make full use of the air outlets arranged on the side wall of the air supply duct, and the airflow can be directed to different places by using air outlets at different positions, which is convenient to use.

[0018] Furthermore, the exhaust vents are staggered vertically.

[0019] Beneficial effect: The staggered arrangement of the air outlets helps to distribute air evenly.

[0020] Furthermore, the dedicated air duct has an air inlet branch, and a dedicated air inlet is located in the air inlet branch.

[0021] Beneficial effect: Connecting the air inlet branch to the air conditioner outlet facilitates the layout of a dedicated air duct.

[0022] Furthermore, the dedicated air duct is made of canvas, foam, tarpaulin, or rubber.

[0023] Beneficial effects: Lightweight, easy to procure, and low cost.

[0052] Embodiment 1 of the vehicle of the present invention:

[0053] In this embodiment, a flexible dedicated air duct is set up inside the existing air conditioning air supply duct. The air treated by the air conditioning is directly introduced into the dedicated air duct from the air conditioning outlet through the dedicated air inlet. The air flows in the dedicated air duct and is then delivered to the passenger compartment through the dedicated air outlet from the air supply duct outlet. The use of a flexible dedicated air duct for air supply can adapt to the space inside the air conditioning air supply duct, reduce abrupt changes in cross-sectional area, avoid the influence of existing air conditioning air supply duct components on airflow, effectively reduce the reduction of airflow kinetic energy due to airflow contact with components, and help ensure the uniformity of airflow from each air supply duct outlet.

[0054] Specifically, such as Figure 4-8 As shown, the vehicle in this embodiment is a bus. The bus includes an air conditioner 1 and an air conditioning duct 2. The air conditioner 1 is installed on the roof, and the air conditioning duct 2 is located on the side of the roof facing the passenger compartment. Air conditioning ducts 2 are located on the left and right sides of the roof, respectively. A left air conditioning outlet 33 communicating with the left air conditioning duct 2 and a right air conditioning outlet 31 communicating with the right air conditioning duct 2 are respectively located on the left and right sides of the roof. The air conditioning duct 2 has a side wall 21 facing the passenger compartment, and an air outlet is located on the side wall 21. A left air conditioning return air vent 34 and a right air conditioning return air vent 32 are also located on the roof corresponding to the passenger compartment to form air circulation. In this embodiment, the front-to-back and left-to-right directions refer to the front-to-back and left-to-right directions of the vehicle.

[0055] The air conditioning duct 2 contains components such as a horn 5 and a diagonal brace 4. To prevent these components from affecting the uniformity of airflow from the air conditioner 1, a dedicated air duct 8 is installed within the air conditioning duct 2. Dedicated air ducts 8 are installed on both the left and right sides of the air conditioning duct 2. These dedicated air ducts 8 are specifically designed for automotive air conditioning. This dedicated air duct 8 is a flexible structure with dedicated air inlets and outlets. The dedicated air inlet connects to the air outlet on the inner wall of the air conditioning duct 2, and the dedicated air outlet connects to the air duct outlet on the inner wall of the air conditioning duct 2. This allows the air processed by the air conditioner 1 to be delivered into the passenger compartment through this dedicated air duct 8. This effectively reduces the reduction of airflow kinetic energy caused by contact between the components within the air conditioning duct 2 and the airflow. When air is delivered through the dedicated air duct 8, the shape of the duct can gradually change along the boundary, reducing the potential hazards caused by internal airflow vortices due to abrupt changes in cross-section. The dedicated air duct 8 is made of canvas, a relatively soft and lightweight material that is easy to procure, low in cost, and not prone to air leakage. The inner wall of the dedicated air duct 8 is a smooth inner wall surface 81, which reduces the resistance to gas flow.

[0056] The dedicated air duct 8 is bonded and fixed to the inner wall of the air conditioning air duct 2 using hook and loop fasteners. The hook and loop fasteners have rough edges on the outer surface of the dedicated air duct 8 and hook edges on the inner wall of the air conditioning air duct 2. The rough edges of the hook and loop fasteners form the bonding part for bonding with the inner wall of the air conditioning air duct 2. By using hook and loop fasteners to bond and fix the dedicated air duct 8 to the air conditioning air duct 2, the dedicated air duct 8 is prevented from drifting with the wind when the air conditioner 1 is working. It also facilitates disassembly and maintenance.

[0057] The dedicated air duct 8 has a main section and an air inlet branch section 85. The main section extends along the air conditioning supply duct 2. The air inlet branch section 85 connects to the main section as a transition between the air conditioning outlet and the main section. A dedicated air inlet is located on the air inlet branch section 85, and a dedicated air outlet is located on the main section. The air inlet branch section connects to the edge of the air conditioning outlet. A Velcro ring is provided at the dedicated air inlet of the dedicated air duct 8 to prevent air leakage after the dedicated air inlet is connected to the air conditioning outlet, allowing air from the air conditioner 1 to enter the dedicated air duct 8. Similarly, a Velcro ring is also provided at the dedicated air outlet to prevent air leakage after the edge of the dedicated air outlet is sealed to the edge of the supply duct outlet.

[0058] Dedicated air vents are installed along the airflow direction in the dedicated air duct 8, according to the seat spacing of the bus. The dedicated air vents in the dedicated air duct 8 include an upper air vent 82, a middle air vent 83, and a lower air vent 84. The middle air vent 83 is larger than both the upper and lower air vents 82 and 84, which are the same size. There are multiple upper air vents 82, middle air vents 83, and lower air vents 84. The side wall 21 of the air supply duct is equipped with air outlets corresponding to the upper air outlet 82, the middle air outlet 83, and the lower air outlet 84. The upper air outlet 82 connects to the normally open air outlet at the top of the air conditioning air supply duct 2. The middle air outlet 83 connects to the adjustable air outlet in the middle of the air conditioning air supply duct 2. The lower air outlet 84 connects to the normally open air outlet at the bottom of the air conditioning air supply duct 2. The upper air outlet 82 connects to the upper normally open air outlet on the side wall 21 of the air supply duct and is mainly used to cool the aisle inside the vehicle, thus preventing the air conditioning unit from overheating. The middle air outlet 83 mainly cools the passengers in the seats and connects to the adjustable air outlet on the side wall 21, allowing for adjustment of air volume and direction. The lower air outlet 84 connects to the lower normally open air outlet on the side wall 21 and mainly cools the side windows, thus preventing fogging.

[0059] Each upper air outlet 82, each middle air outlet 83, and each lower air outlet 84 are arranged in a row in the front-to-back direction. That is, the dedicated air outlets on the dedicated air duct 8 are arranged in three rows in the vertical direction, and the upper air outlet 82, middle air outlet 83, and lower air outlet 84 are staggered vertically to facilitate uniform airflow.

[0060] The main section of the dedicated air duct 8 has a gradually decreasing cross-sectional area along the airflow direction. Utilizing the relatively independent dedicated air duct 8 compared to the original air conditioning duct 2, the cross-section of the airflow channel can be designed separately, resulting in a gradually decreasing cross-sectional area along the airflow direction in the main section of the dedicated air duct 8. This means the cross-sectional area is larger near the air conditioning unit and smaller further away. This regulates the airflow velocity, maintains uniform air pressure, and improves the uniformity of airflow from all outlets in the air duct, thus enhancing the uniformity of airflow from the air conditioning unit 1. Air conditioning uniformity refers to the ability of the vehicle's air conditioning unit 1 to evenly deliver cold, hot, or fresh air from each outlet to the vehicle interior within a certain tolerance range. When the air conditioning unit 1 is turned on, air enters the dedicated air duct 8, fills the duct, and is then delivered into the vehicle interior through the outlets. After mixing with the interior air, the air returns to the interior of the air conditioning unit 1, reducing airflow resistance within the duct and mitigating the risk of uneven airflow from some outlets due to excessive local resistance.
