Description

Technical Field

[0001] The invention belongs to the technical field of automobile equipment, and in particular relates to an air duct wind guide device for a passenger car. Background Art

[0002] Air conditioning is a basic component for regulating the temperature in the passenger compartment of a bus. It is usually installed on the top of the vehicle body. Due to the limitation of the vehicle body structure, the air conditioning of a bus cannot be installed exactly in the middle of the roof, resulting in the air conditioning's cold and hot air not being evenly distributed to the space in the compartment, causing uneven temperature in the front and back of the compartment. For new energy buses, uneven temperature in the compartment will increase the power consumption of the electric air conditioning, thereby reducing the vehicle's driving range.

[0003] At present, most OEMs have not improved the air ducts of the air conditioner to promote the uniform distribution of cold and hot air from the air conditioner to various positions in the car. They only give priority to ensuring the cooling and heating needs of the driver. The general solution is to adjust the installation position of the air conditioner so that the air outlet of the air conditioner is as close to the front of the vehicle as possible, without considering the rationality of the front and rear axle load distribution of the vehicle.

[0004] In the existing public technology, there is no device specifically for adjusting the front and rear flow rate of the air conditioning cooling and heating air in the air duct, and the existing vehicles only prioritize the cooling and heating needs of the driver by changing the installation position of the air conditioner on the top of the vehicle body, without considering the rationality of the air conditioning layout.
