Description

Technical Field

[0001] This utility model relates to the field of bus ventilation equipment, and in particular to a decorative part for a bus air conditioning inlet and a bus. Background Technology

[0002] Bus air conditioning is a device that controls the temperature and fresh air exchange in the bus cabin, providing a comfortable riding environment for the driver and passengers. Currently, most bus air conditioners are roof-mounted, with the air conditioning unit and air inlet located on the outer top of the vehicle body. This design results in the air conditioning unit protruding from the roof, which is aesthetically unappealing, takes up a lot of space, and raises the overall center of gravity of the vehicle, reducing its stability.

[0003] To address the aforementioned issues, existing passenger vehicles typically employ built-in air conditioning units. These units are positioned on the top of both sides of the passenger compartment and extend along the vehicle's body. This configuration necessitates the installation of air inlets on the top of both sides of the passenger compartment, corresponding to the air inlets' locations. To prevent rainwater and debris from entering the air inlets, existing technologies employ decorative elements to cover them, thus keeping rainwater and debris out without affecting the airflow function. For aesthetic purposes, these decorative elements are often elongated strips extending along the length of the vehicle body.

[0004] However, the existing technology has the following problems: since the length of buses is mostly around 6-18 meters, the decorative parts used to cover the air intake are mostly set up in sections. During the installation of multiple decorative parts, the installation angle between adjacent decorative parts is adjusted manually, which makes it difficult to guarantee the overall installation angle and straightness of the decorative parts after all decorative parts on the same side are installed on the bus. In addition, during the assembly of the whole vehicle, the independent decorative parts need to be installed on the bus one by one, which is cumbersome and prolongs the assembly time of the bus. Utility Model Content

[0005] The purpose of this utility model is to provide a decorative part for the air conditioning inlet of a bus, so as to solve the problems of cumbersome assembly process, low installation accuracy, and long assembly time of the air conditioning inlet decorative parts in the prior art.
