Arrangement structure of reinforcing ribs for back door trim panel

Abstract

The invention discloses an arrangement structure of reinforcing ribs for a back door trim panel. The arrangement structure comprises the back door trim panel, and longitudinal reinforcing ribs and transverse reinforcing ribs arranged vertically and horizontally on the back door trim panel in an intersecting manner. The arrangement structure is characterized in that the transverse reinforcing ribs are in a concave-convex form being higher on one segment and lower on the other, and the interval between every two adjacent concave segments is the distance between two continuous or three continuous longitudinal reinforcing ribs. By adopting the arrangement structure, deformation caused by the contraction difference between the reinforcing ribs and a main body in the cooling process of the back door trim panel can be reduced by reasonably optimizing the arrangement of the reinforcing ribs on the premise of not influencing the overall rigidity of parts, so that the effects of reducing the deformation of the back door trim panel and improving the trim quality are achieved.

Description

technical field

[0001] The invention relates to automobile parts, in particular to an arrangement structure of reinforcing ribs of a back door trim panel. Background technique

[0002] With the rapid development of the automobile industry, the application of plastic parts is becoming more and more extensive. The design of ribs in interior and exterior design is also an important part that affects product quality. Generally speaking, the ribs have three main functions: functional ribs, which play a role in positioning and supporting in the assembly assembly; flow diversion, which guides the flow pattern in the forming of parts; reinforcement, which increases the overall rigidity of the parts.

[0003] For parts with a flat overall surface and a large area, in order to increase the rigidity of the part surface, some crisscross ribs are generally designed on the part surface. This design will increase the surface stiffness of the part, but it will also cause assembly defects ...

Embodiment Construction

[0019] The structure of the present invention is described in detail below in conjunction with accompanying drawing:

[0020] Such as figure 1 As shown, 13 is the main wall of the back door trim. Among them, 1, 2, 3, 4, 5, 6, 7, 8, and 9 are the first to ninth longitudinal ribs, 10, 11, and 12 are the first, second, and third transverse ribs, and the transverse ribs and The longitudinal ribs form a criss-cross connection rib design. On the basis of the original design, the present invention keeps the design of the original longitudinal rib position unchanged, reduces the heights of the three transverse ribs 10, 11 and 12 between the longitudinal rib 1 and the longitudinal rib 2; reduces the longitudinal rib 3 and the longitudinal rib The height of the three transverse ribs 10, 11 and 12 between the ribs 4; the height of the three transverse ribs 10, 11 and 12 between the longitudinal ribs 6 and 7; the height of the longitudinal ribs 8 and 9 The height of the three transvers...
