Description

Technical Field

[0001] The utility model is applied to the technical field of pipeline protection, and particularly relates to a vehicle roof pipeline protection cover structure. Background Art

[0002] In recent years, the overseas pure electric bus passenger transport market has seen an increasing demand. For example, in the European market, local customers are keen on low-floor, high-passenger-capacity structures. In order to meet this demand, most vehicle manufacturers at home and abroad will adopt a solution where the power battery is placed on the roof. This solution results in the placement of a battery liquid cooling system, a charging device, and related control assemblies on the roof in addition to the power battery pack. Coupled with the traditional structure of the roof-mounted air conditioner, the roof will be covered with various electrical components, and the number of pipelines on the roof will increase significantly. Based on the traditional roof pipeline layout solution, in order to ensure the reliability of pipeline use, the pipeline is generally arranged inside the air duct in the car. However, the traditional layout solution has the disadvantage of not being able to arrange too many pipelines. Therefore, in order to avoid the pipelines from blocking the air duct of the air conditioner, and to make the layout of the top electrical components more reasonable and convenient for maintenance, these pipelines will be arranged directly on the roof. The pipelines on the roof are directly exposed to the outside for installation. Since the external materials of the pipelines are mainly plastic, long-term exposure to light will accelerate their aging. These pipelines include the liquid cooling pipelines of the power battery, the low-voltage wiring harnesses and high-voltage wiring harnesses of various components. If the surface shows aging and cracking problems, component failures may occur on the light side, and safety accidents may occur on the heavy side. Protecting the roof pipelines and improving their reliability and safety during use cannot be ignored. Metal joints and metal hoops are used at some pipe joints. Long-term direct exposure to the outside may cause premature corrosion and eventually lead to premature failure of their functions. If a roof pipeline protection cover structure with a simple structure can be designed, which can protect the pipelines on the roof of pure electric buses from direct sunlight and rain, and can partition the pipelines for protection without interfering with each other, the above problems can be solved.
