AI Technical Summary

Technical Problem

The existing automotive side panel is complicated to disassemble when damaged, requiring the removal of multiple parts, has poor interchangeability, and traditional sheet metal side panels are heavy and have high development costs.

Method used

The side panel is connected to the four corner windows using a snap-fit ​​method. The snap-fit ​​is achieved by setting a slot on the inner panel and snapping it with a buckle on the body sheet metal. The side panel is manufactured by injection molding with plastic particles, reducing the use of traditional sheet metal parts.

Benefits of technology

It enables convenient disassembly and improved interchangeability of the side panel outer panels, reduces the overall vehicle weight and development costs, and simplifies the disassembly process.

Abstract

This invention relates to the field of automotive technology and discloses a connection structure and installation method for an automotive side panel outer panel. The structure includes an outer side panel, with an inner panel connected to the inner side of the outer side panel near its top edge. The top of the outer side panel is used to abut against the four corner window glass. A slot is provided at the end of the inner panel away from the outer side panel, and the outer side panel is engaged with a buckle on the vehicle body sheet metal via the slot. This invention solves the problem of inconvenient disassembly of traditional plastic side panels. Traditional plastic side panels require the removal of peripheral components, top beams, doors, and other products that require the plastic side panel for assembly before disassembly. This invention eliminates the traditional pressing method, allowing the plastic side panel outer panel to be disassembled without removing the glass. It can replace traditional sheet metal side panels, solving the problem of non-interchangeability of side panel outer panels.
