Car cover action
The main role of the car cover (hood) includes the following aspects :
Protect the engine and surrounding parts : Under the hood are the important parts of the car, including the engine, circuit, oil circuit, brake system and transmission system. The hood is designed to effectively prevent the impact of adverse factors such as shock, corrosion, rain and electrical interference on the vehicle, thereby protecting the normal operation of these critical components .
air diversion : The shape of the hood can adjust the direction of air flow around the car, reducing the impact of air resistance on the movement of the car. Through the diversion design, the air resistance can be broken down into beneficial forces, enhance the front wheel grip on the ground, conducive to the stability of the car .
Aesthetics and personalization : The exterior design and material choice of the hood can also affect the overall beauty of the car. Different models and design styles can be reflected through the shape and material of the hood, increasing the beauty and personalization of the vehicle .
sound insulation and heat insulation : the structure of the hood usually contains thermal insulation materials, which can effectively isolate the heat and noise generated by the engine working, providing a more comfortable driving environment .
auto cover fault mainly includes the following situations:
The cover does not open or close properly : this may be due to the cover locking mechanism failure, locking mechanism blocked, lock mechanism failure, opening line problems or hood damage caused by other reasons. Solutions include checking and repairing or replacing the locking mechanism, cleaning the locking mechanism, checking and repairing the wiring problem .
The cover springs up on its own during driving : this is usually caused by damage to the cover lock mechanism or a short circuit of the related line. In this case, you should immediately stop and re-lock the cover, if the problem occurs repeatedly, it is recommended to go to a professional repair shop for inspection and repair .
cover jitter : For example, the cover jitter problem of Changan Ford Mondeo model at high speed may be due to unreasonable cover materials and design, resulting in shaking under the influence of wind resistance and wind pressure at high speed. This situation may affect driving safety, the owner should feedback to the manufacturer and seek solutions .
The cover makes abnormal noise : this may be caused by loose or damaged parts inside the cover. For safety reasons, you should go to a professional auto repair shop as soon as possible for detailed inspection and repair .
The common materials of automobile cover include steel plate, aluminum alloy, carbon fiber, ABS engineering plastic and so on . Among them, steel plate is the most common material, due to its high strength and stiffness, and relatively low cost .
The aluminum alloy cover is favored for its lightweight characteristics, which can effectively reduce the weight of the vehicle and improve fuel economy .
Carbon fiber materials are mostly used in high-end models or supercars due to their lightweight, high performance and environmental protection properties, but the cost is higher .
In addition, some high-end models will also use ABS engineering plastics, because of its excellent impact resistance, heat and cold resistance characteristics and wear and corrosion resistance .
Characteristics and application scenarios of different materials
steel plate : high strength, low cost, suitable for most models, especially city coupe and SUV.
aluminum alloy : light weight, high strength, often used in luxury cars and high-end models, can effectively reduce vehicle weight, improve fuel efficiency .
carbon fiber : lightweight, high performance, mostly used in high-end supercars or racing cars, the cost is higher .
ABS engineering plastics : strong impact resistance, heat and cold resistance, wear resistance and corrosion resistance, suitable for the need of high protection performance .
Special materials and their functions
rubber foam and aluminum foil : used to reduce engine noise, isolate heat, protect paint, prevent aging .
EVA soundproof foam : used to improve the sound absorption of the cabin cover, reduce engine noise and enhance the driving experience .
