Description

Technical Field

[0001] This utility model relates to automotive injection molded interior parts, and in particular to an automotive rear door sill pressure plate assembly. Background Technology

[0002] Due to limited assembly space, small mating surfaces between parts, poor visibility for assembly workers, and insufficient assembly space, the fit between the tailgate sill plate and the pillar of a car often exhibits quality defects such as poor appearance, a stepped feel, uneven mating gaps, and incomplete assembly.

[0003] With the continuous development of automotive lightweighting, people demand that automotive parts be lightweight and recyclable to facilitate resource conservation and environmental protection. The exterior and interior of automotive steel structures are basically all made of plastic. In order to achieve the overall aesthetics of the car and for more and more personalized modifications, the initial design of the car is required to facilitate subsequent modifications. Taking the plastic material as the tailgate sill plate as an example, in the existing technology, the material of the left rear sill plate assembly is generally plastic. There are still many in the market that rely entirely on clips and C-pillar lower guard plates. Moreover, most of these upper guard plates have clips that are either integrally injection molded or separately clipped to the inside of the upper guard plate. In particular, the internal connection control structure of the left rear sill plate is prone to movement and instability of the internal installation components during use. Utility Model Content

[0004] The purpose of this utility model is to provide a car tailgate sill plate assembly that solves the problem of stable connection between the car tailgate sill plate assembly and other assemblies.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a car rear door sill plate assembly, including a rear door sill plate body, a cover plate body disposed in the rear door sill plate, sound insulation cotton matching the back of the rear door sill plate, and a spring assembly disposed between the left rear door sill plate body and the cover plate body. The rear door sill plate body is rectangular and has a main mounting hole. A mounting step is provided at its bottom end. A support member is mounted at the bottom of the upper part of the mounting step and a side abutment mounting member body is disposed on the upper part of the mounting step. An installation positioning member assembly and an external seat assembly are disposed in the rear door sill plate body. The external seat assembly includes a left external seat, a middle first external seat, a middle second external seat, and a right external seat.

[0006] Left and right fixing clips are installed at both ends inside the rear door sill pressure plate body.

[0007] The spring assembly is located in the spring sleeve on the rear door sill pressure plate body.

[0008] The rear door sill pressure plate body has a reinforcing edge at the bottom.

[0009] The beneficial effects of this utility model are as follows: the flush outer circumference of the rear door sill plate with the straight section ensures the appearance quality of the car sill assembly; the simple and quick installation between the plate's fixing connection structure and the insertion holes, positioning holes, and connecting holes on other assemblies significantly improves the assembly efficiency of the rear door sill plate and the pillar interior panel. Furthermore, its stability during use is further enhanced.

[0010] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments. Attached Figure Description
