Problems solved by technology

For the welding process, during the operation of the vehicle, due to factors such as roads and driving operations, it is easy to cause desoldering of solder joints and tearing of the skin, so there is a problem with the sealing, and the vehicle has a hidden danger of water leakage
For the riveting process, the production process is cumbersome, that is, it needs to be glued (the sealing effect and the damping between the top cover skin and the top cover frame), punching holes, and pulling the rivets, and the rivets need to be glued (easy to seal) , and the straightness of the solder joints and welds of the rivet machine also need to be constrained so that the glue seam can be covered by the coating, otherwise the glue seam will widen, reducing the aesthetics and increasing the cost

Embodiment Construction

[0017] The present invention is described in detail below in conjunction with accompanying drawing and specific embodiment:

[0018] Such as figure 1 and figure 2 As shown, the roof frame 1 is fixed with a side roof skin 3 and a middle roof skin 2, the upper part of the side roof skin 3 is fixed on the top surface of the roof frame 1, and the edge of the middle roof skin 2 is fixed on the side On the edge of the top skin 3 upper part. A thick rubber pad 4 is arranged between the middle roof skin 2 and the roof frame 1, a thin rubber pad 5 is arranged between the edge of the middle roof skin 2 and the upper edge of the side roof skin 3, the thick rubber pad 4 and the thin rubber pad The rubber pads 5 are evenly distributed at fixed intervals. The middle roof skin 2 is a flat structure, and the upper part of the side roof skin 3 is a flat structure.

[0019] The thick rubber pad 4 is 4mm thick, and the thin rubber pad 5 is 1mm thick.

[0020] The side top skin 3 is made of...

Abstract

The invention belongs to the technical field of coaches, and relates to a coach roof skin, in particular to a bonding type coach roof skin. The bonding type coach roof skin comprises side top skins and a middle top skin which are fixed on a roof framework, the upper parts of the side top skins are fixed on the top surface of the roof framework, and the edges of the middle top skin are fixed on theedges of the upper parts of the side top skins. The side top skins are made of glass fiber reinforced plastic, the middle top skin is an aluminum plate, the side top skins and the middle top skin arebonded to the roof framework, and the edges of the middle top skin are bonded to the edges of the upper parts of the side top skins. The middle top skin and the side top skins are fixed in a bondingmode, the connecting structure is simple, no fire operation is needed during installation and later maintenance, and operability and safety are good. The side top skins are made of glass fiber reinforced plastic, can be formed through a mold, and can be independently repaired through a glass fiber reinforced plastic repair process after being damaged, and production and later maintenance are facilitated.

Description

technical field [0001] The invention belongs to the technical field of passenger cars, and in particular relates to a passenger car top cover skin. Background technique [0002] At present, the skin material of the middle part of the domestic bus roof is mainly galvanized sheet, and some vehicles also have aluminum sheet. The assembly process is mainly welding (electric welding, broken welding) and riveting (riveting spacing ranging from 100 to 200). For the welding process, during the operation of the vehicle, due to factors such as roads and driving operations, it is easy to cause desoldering of solder joints and tearing of the skin, so there is a problem with the sealing performance, and there is a hidden danger of water leakage in the vehicle. For the riveting process, the production process is cumbersome, that is, it needs to be glued (the sealing effect and the damping between the top cover skin and the top cover frame), punching holes, and pulling the rivets, and the ...
