Coach top side skin with novel structure and preparation method thereof

Abstract

The invention discloses a coach top side skin with a novel structure and a preparation method thereof. The coach top side skin comprises a reinforcing rib, an arc-shaped skin, a water flow channel and an upper window edge seam allowance; the arc-shaped skin is of an arc-shaped sheet structure and is positioned on the side edge of the top of a coach; the reinforcing rib is positioned in the position, approaching to a straight line, of the upper surface of top side skin and is connected with the upper edge of the arc-shaped skin; the water flow channel is made of a double-layer plate material, is positioned at the junction of the top of the coach and a coach window, and is connected with the lower edge of the arc-shaped skin; the upper window edge seam allowance is positioned below the water flow channel; the reinforcing rib, the arc-shaped skin, the water flow channel and the upper window edge seam allowance form a steel plate through rolling. The coach top side skin disclosed by the invention has the advantages of ingenious structure, low manufacturing cost, simple preparation process, low construction intensity, low maintenance cost and the like.

Description

technical field [0001] The invention relates to the field of passenger car skins, in particular to a passenger car top side skin with a new structure and a preparation method thereof. Background technique [0002] At present, in the design and production of existing large and medium-sized passenger cars, after the conventional passenger car finishes the painting process, it is necessary to install a special passenger car running water tank on the upper edge of the side window glass. The mold is extruded, and a series of high-level operations need to be manually performed during installation, such as: bonding masking paper in advance, brushing the primer, applying adhesive glue, etc. During the installation process, it is necessary to manually bond the flow tank and fix it with self-tapping screws. It is extremely inconvenient to clean the excess glue and remove the masking paper after the bonding is firm; in addition, according to the feedback information from the market, af...

[0002] At present, in the design and production of existing large and medium-sized passenger cars, after the conventional passenger car finishes the painting process, it is necessary to install a special passenger car running water tank on the upper edge of the side window glass. The mold is extruded, and a series of high-level operations need to be manually performed during installation, such as: bonding masking paper in advance, brushing the primer, applying adhesive glue, etc. During the installation process, it is necessary to manually bond the flow tank and fix it with self-tapping screws. It is extremely inconvenient to clean the excess glue and remove the masking paper after the bonding is firm; in addition, according to the feedback information from the market, after some buses have been used for a period of time (mostly 3-4 years), the original self-tapping screws will be lost. It is prone to rust, causing water-like rust on the outside of the car body. In severe cases, rainwater may even flow into the car through the self-tapping screws, seriously affecting the appearance and sealing effect of the bus itself
