A spoiler frame disassembly structure

Abstract

This utility model relates to the field of automotive parts technology, specifically to a spoiler frame disassembly structure, including a frame body, a textured decorative part, and multiple snap-fit ​​mechanisms. The frame body has a C-shaped easily deformable area with several reinforcing ribs. The frame body is made of PC+ABS. Five trapezoidal reinforcing ribs, 1.2mm thick, are provided on the back of the C-shaped easily deformable area, with a 4mm clearance from the outer surface. The textured decorative part is made of PP+EPDM-TD30, and its back integrates four sets of snap-fit ​​mechanisms with a 0.3mm interference fit and a 0.1mm positioning gap with the frame body, enabling quick installation. The hidden stiffness of the reinforcing ribs increases by 35%, and high-speed wind vibration displacement decreases by 40%. There is no shrinkage, and the appearance passes inspection on the first attempt. The snap-fit ​​mechanism allows for quick disassembly, reducing the time from 45 seconds to 8 seconds. The material separation scheme reduces costs. The decorative part can be disassembled without damage in 4 seconds, facilitating after-sales maintenance. This solves the problems of shrinkage and insufficient stiffness caused by ribs in the C-shaped area in existing technologies.

Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a spoiler frame disassembly structure. Background Technology

[0002] Currently, most spoilers are injection molded with the frame and the textured surface as a single unit. Due to the large C-shaped span structure of the rear spoiler, reinforcing ribs are often added to the back to ensure rigidity.

[0003] However, the reinforcing ribs can cause shrinkage marks in the textured area of ​​the front spoiler, affecting its appearance; reducing the amount of ribs, on the other hand, can cause the spoiler to vibrate, deform, or even crack at high speeds. Therefore, how to improve structural strength while avoiding appearance defects has become an industry challenge. Utility Model Content

[0004] The purpose of this utility model is to provide a spoiler frame disassembly structure, which aims to solve the problems of shrinkage and insufficient rigidity caused by the reinforcement of the C-shaped area in the prior art.

[0005] To achieve the above objectives, this utility model provides a spoiler frame detachable structure, including a frame body, a textured decorative piece, and multiple snap-fit ​​mechanisms; the frame body has a C-shaped easily retractable deformation area, the C-shaped easily retractable deformation area is provided with several reinforcing ribs, and the multiple snap-fit ​​mechanisms are all disposed on the back of the textured decorative piece, the textured decorative piece is detachably installed on the frame body through the snap-fit ​​mechanisms.

[0006] The locking mechanism includes a locking connector and a locking tongue. The locking connector is fixedly connected to the leather-textured decorative piece and is located on one side of the leather-textured decorative piece. The locking tongue is fixedly connected to the locking connector and is located on the locking connector.

[0007] The frame body has multiple snap-fit ​​holes, which are adapted to the locking tongue and the snap-fit ​​connector.

[0008] The leather-textured decorative piece has two elastic buckles, which are respectively located on the two sides of the leather-textured decorative piece.

[0009] The skeleton body has two locking holes, which are adapted to two elastic buckles.

[0010] This utility model discloses a spoiler frame disassembly structure, comprising a frame body, a textured decorative piece, and multiple snap-fit ​​mechanisms. The frame body has a C-shaped easily retractable deformation area, which is provided with several reinforcing ribs. Multiple snap-fit ​​mechanisms are located on the back of the textured decorative piece, allowing the decorative piece to be detachably mounted to the frame body via these mechanisms. The frame body is made of PC+ABS. Five trapezoidal reinforcing ribs, 1.2mm thick, are provided on the back of the C-shaped easily retractable deformation area, with a 4mm clearance from the outer surface. The textured decorative piece is made of PP+EPDM-TD30, with four sets of snap-fit ​​mechanisms integrated on its back, interfering with the frame body by 0.3mm and having a positioning gap of 0.1mm, enabling quick installation. The hidden stiffness of the reinforcing ribs is increased by 35%, and high-speed wind vibration displacement is reduced by 40%. No shrinkage is observed, ensuring a first-time pass for appearance inspection. The snap-fit ​​mechanism reduces installation time from 45 seconds to 8 seconds. The material separation scheme reduces costs. The decorative piece can be disassembled without damage in 4 seconds, facilitating convenient after-sales maintenance. This solves the problems of shrinkage and insufficient rigidity caused by stiffening of the C-shaped area in the existing technology. Attached Figure Description
