Description

Technical Field

[0001] The utility model relates to the technical field of automotive air duct systems, and more specifically, to an air outlet duct for a vehicle. Background Art

[0002] In modern automobiles, the face-blowing air duct in the instrument panel is one of the core components of the air-conditioning ventilation system. Its main function is to effectively transmit cold air or hot air to each air outlet, thereby achieving precise adjustment of the temperature in the passenger compartment. The sealing performance of the connection part between the face-blowing air duct and the air-conditioning system is crucial for the air supply efficiency and directly affects the temperature control effect inside the vehicle.

[0003] With the popularization of electric vehicles, the air-conditioning system has become one of the main noise sources in the passenger compartment, significantly affecting the comfort of the whole vehicle. Among them, the noise control at the air-conditioning pipe orifice is particularly critical. To reduce noise, traditional air-conditioning noise reduction pipes mostly use polyethylene terephthalate (PET) materials. However, the PET air outlet duct is prone to abnormal noise at the connection, which not only affects the quietness of the air-conditioning but also may cause discomfort to passengers. Summary of the Invention

[0004] The utility model aims to solve one of the technical problems in the related technologies to a certain extent. For this purpose, the utility model provides an air outlet duct for a vehicle, which effectively improves the sealing performance and quietness of the air-conditioning system and significantly improves the comfort experience of vehicle passengers.

[0005] The technical solution adopted by the utility model is: to provide an air outlet duct for a vehicle, including a left face-blowing air duct assembly, a right face-blowing air duct assembly, and a central face-blowing air duct assembly;

[0006] Wherein, the central face-blowing air duct assembly includes a central housing and a sealing sponge, and the sealing sponge is located between the central housing and the left face-blowing air duct assembly, and between the central housing and the right face-blowing air duct assembly;

[0007] Both the left face-blowing air duct assembly and the right face-blowing air duct assembly are made of PET material;

[0008] The left face-blowing air duct assembly and the right face-blowing air duct assembly are connected to the central housing through fasteners passing through the sealing sponge.

[0009] After adopting the above structure, the setting of the fasteners effectively enhances the connection strength between components, thereby improving the overall sealing performance. The introduction of the sealing sponge not only physically isolates the air flow in different air ducts, reducing the air flow interference between the air ducts, but also effectively absorbs the vibration and noise generated at the air duct joints, thus significantly reducing the operating noise of the air conditioning system. In addition, since both the left face-blowing air duct assembly and the right face-blowing air duct assembly are made of PET material, they have good heat resistance and corrosion resistance, can adapt to the complex working environment inside the vehicle, and improve the service life. Through the optimized air duct design, not only the air circulation efficiency inside the vehicle is improved, but also a quieter and more comfortable riding experience is provided for passengers.

[0010] According to an embodiment of the present invention, the left face-blowing air duct assembly includes an upper left housing, a lower left housing, and a left air outlet connector. The upper left housing and the lower left housing are combined to form a pipeline structure, and the left air outlet connector is fixedly connected to one end of the pipeline structure; an effective air outlet is formed to ensure that cold air or hot air can be smoothly delivered into the vehicle.

[0011] According to an embodiment of the present invention, the left air outlet connector is provided with a first fastening hole.

[0012] According to an embodiment of the present invention, the right face-blowing air duct assembly includes an upper right housing, a lower right housing, and a right air outlet connector. The upper right housing and the lower right housing are combined to form a pipeline structure, and the right air outlet connector is fixedly connected to one end of the pipeline structure; it constitutes the air outlet of the right face-blowing air duct, effectively transmitting the cold air or hot air processed by the air conditioner to the passenger compartment. The fixed connection design of the right air outlet connector ensures the stability of the air outlet, avoiding loosening and air leakage caused by vehicle vibration or external impact.

[0013] According to an embodiment of the present invention, the upper right housing is provided with an avoidance groove.

[0014] According to an embodiment of the present invention, the upper right housing is provided with a flange, and the flange is adapted to the right air outlet connector to form a reliable connection interface, ensuring airtightness and structural stability. The design of this flange not only enhances the strength of the connection part, but also effectively prevents leakage that may be caused by temperature changes and air flow pressure fluctuations.

[0015] According to an embodiment of the present invention, the upper right housing is provided with a positioning notch.

[0016] According to an embodiment of the present invention, the right air outlet connector is provided with a second fastening hole.

[0017] According to an embodiment of the present utility model, the sealing sponge is provided with a left through-hole and a right through-hole. The left face-blowing air duct assembly is aligned with the left through-hole, and the right face-blowing air duct assembly is aligned with the right through-hole, forming an effective air circulation path. The design of the left through-hole and the right through-hole ensures that cold air or hot air can be smoothly conveyed from the left face-blowing air duct assembly and the right face-blowing air duct assembly to the passenger compartment.

[0018] According to an embodiment of the present utility model, the sealing sponge is further provided with a defrosting air duct. The design of the defrosting air duct is used to guide the air flow, help quickly remove the frost or fog on the window, and improve the clarity of the driving vision.
