(V) Roof Panel Assembly

Roof panel assembly is mainly composed of parts such as roof panel, roof front cross member, roof central

reinforcement, roof rear cross member, etc., by welding them together. Shown as the dismantle diagram 5-

6.Roof interior trim is mounted inside; and an insulation mat is pasted in its interlayer. Cohesive binder is

applied between the front/central/rear cross member and the roof panel in many points. The rainwater from

the roof panel flows out of the rear body through roof drip channel that are on the both sides of the roof panel.

Cross members and reinforcement members are used to strengthen the rigidity of the roof panel in trans-

verse direction.

(VI) Trunk Shelf Assembly

Trunk shelf assembly is mainly composed of parts such as trunk shelf panel, trunk shelf front reinforcement

plate, drip channel etc., by welding them together.

Trunk shelf is welded to the LH/RH quarter, which and rear floor, the back of the quarter form a trunk.

Meanwhile, a frame that can resist to torsion is also generated. Figure 5-7 is the dismantle diagram.

II. Removable Sheet Metal Parts

(I) Engine Hood, Front Fender

1. Engine hood is mainly used to protect the engine, meet the whole vehicle design, and make the mainte-

nance convenient. It also has an effect of isolating the engine noise. The engine hood has a double-insurance

lock system. The release of the first lock is controlled by the drawing cable that is under the instrument panel.

As to the release of the second lock, you should firstly release the first one and the hood will open, and then

move the hood lock hook. The double-insurance lock system is designed for safety, especially in the course

of running with a high-speed, to prevent the engine hood from being raised, which often causes traffic

accidents. The angle of the hood that is fully opened is 52°.As shown in Figure 5-8

(III) Door Assembly

The door adopts limit hinges. The hinge is mounted on the front pillar of the door frame.

A door is mainly composed of the door outer and inner plate, anti-impact bar and door reinforcement plate.

The structure of the door is complicated, because it is a movable part. It is designed to form a sealed

compartment with the main body and relevant parts, and also convenient for drivers and passengers to get in

and out of the vehicle. And the devices on the door have to bear high-frequency operation. So it must meet

very high requirements in reliability and durability.

The inner and outer plates are both molded from a whole steel plate, which is for improving the rigidity and

assembly accuracy. In order to assure the safety when the vehicle is crashed on the side of the body; anti-

impact bar and central reinforcement plate are equipped in the door.

Door plate assembly is composed of the outer and inner sub-assemblies. Use a special folded edge machine

to wrap along the full circle of the door outer plate and the inner plate sub-assemblies to get them together.

(IV) Trunk Lid Welding Assembly

Trunk lid assembly is mainly composed of parts such as trunk lid outer plate, trunk lid inner plate, trunk lid

hinge mounting plate, trunk lid lock mounting plate, etc., by welding them together. As shown in Figure 5-12
