Anxious, accurate point of the answer, so I went to the computer plus points to accept the two answers
The trunk lid requires a good rigidity, the structure is basically the same as the hood, but also the outer and inner plates, the inner plate has stiffeners. Some of the cars, known as the "half car half", extend their luggage upwards, including the rear windshield, which increases the area of ??the opening, forming a door, hence the so-called back door, which keeps a sedan Shape and can easily store items. The fender is the outer panel of the car that covers the wheel, named after the shape and position of the old body. According to the installation location is divided into the front fender and rear fender, the front fender installed in the front wheel, it must ensure that the front wheel rotation and beating the maximum limit space, so the designer will be selected according to the tire Model size Use the "wheel beats" to verify the design dimensions of the fender. The dash panel is the partition between the engine compartment and the compartment, which is connected to the floor and the front pillar, and the car body is installed under the front cover. There are many holes in the front panel, as the manipulation of the cable, drawbars, piping and wire harness through the use, but also with the pedal, square ask the column and other mechanical installation location.
The roof is the cover of the top of the car. For the overall stiffness of the car body, the roof is not very important car body parts, which is allowed to open the roof on the roof of the reasons. From the design point of view, it is important how it is smooth with the front and rear window frame and the pillar at the junction of the transition, in order to obtain the best visual sense and the smallest air resistance. Of course, in order to safety roof cover should also have a certain strength and stiffness, generally under the roof to increase the number of reinforcement beam, the top cover laying insulation pad material to prevent the outside temperature and reduce the vibration of the vibration transfer.
The engine cover (also known as the hood) is the most eye-catching body components, is often a car to see one of the components. The main requirement for the engine cover is insulation, its own light weight, strong rigidity.
Part 2. Inside and outside the car. Interior and exterior.
Chassis, suspension, drive axle
