Description

Technical Field

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

[0002] Due to limited assembly space, small mating cross-sections between parts, poor visibility for employees during assembly, and insufficient assembly space, the mating of car door sill plates and pillars often results in quality defects such as poor appearance, a stepped feel, uneven mating gaps, and incomplete assembly.

[0003] With the continuous development of lightweight vehicles, people demand that automotive parts be lightweight and recyclable to facilitate resource conservation and environmental protection. The exterior and interior steel structures of automobiles are now almost entirely made of plastic. To ensure the overall aesthetics of the car and facilitate increasing personalization, the initial design must allow for future modifications. For example, plastic materials are used for car door sill trim.

[0004] In the prior art: Publication (announcement) number: CN220535570U, an assembly structure for an automobile door sill plate is provided. The outer wall of the inner groove of the straight end section is provided with insertion holes, and the bottom of the groove at the top is provided with positioning holes and connecting holes. The insertion holes, positioning holes and connecting holes are connected in the vertical direction. The door sill plate is provided with connecting clips, connecting claws and positioning pins that form a vertical insertion fit with the above-mentioned insertion holes, positioning holes and connecting holes.

[0005] In the aforementioned prior art, the material of the rear door sill plate assembly is generally plastic. In the market, there are still many products that rely entirely on clips and C-pillar lower guard plates. In most of these, the clips of the upper guard plate 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 door sill plate is prone to the phenomenon of unsmooth movement of the internally installed components during use. Utility Model Content

[0006] The purpose of this utility model is to provide a car rear door sill plate assembly to solve the problem of secure connection of the car left rear door sill plate.

[0007] The technical solution adopted by this utility model to solve its technical problem is: a car rear door sill plate assembly, including a sill plate body and a fixed connection structure disposed in the sill plate body. The sill plate body is C-shaped. The fixed connection structure includes an external snap-fit ​​assembly and a side snap-fit ​​assembly disposed on the upper part of the sill plate body. An inner reinforcing forming block structure is provided at the inner bend of the sill plate body. The inner reinforcing forming block structure includes a right reinforcing rib assembly, a middle reinforcing rib assembly and a left reinforcing rib assembly. A docking snap post is provided near the upper inner edge of the sill plate body.

[0008] Internal locking seats are provided on the outer sides of the central reinforcing rib group and the left reinforcing rib group.

[0009] The side-end snap-fit ​​assembly has a C-pillar lower guard plate snap-fit ​​hole in the sill pressure plate body on the outer side.

[0010] The lower part of the threshold plate body is provided with an external reinforcing end edge.

[0011] The beneficial effects of this utility model are as follows: By setting an inner reinforcing molding block structure at the inner curve of the sill plate body in the left rear sill plate structure of the automobile, the product's firmness is improved. Furthermore, the connection structure for connecting to the C-pillar lower guard plate, as well as the external snap-fit ​​assembly and the side snap-fit ​​assembly, prevents displacement or even detachment during use, increases service life, and avoids frequent replacements due to insufficient connection strength.

[0012] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0020] The terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end" used in the application text to indicate the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings. They are used solely for the convenience of describing the present invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Example 1, such as Figure 1-6 As shown, a car rear door sill plate assembly includes a sill plate body 1 and a fixed connection structure disposed within the sill plate body. The sill plate body 1 is C-shaped. The fixed connection structure includes an external snap-fit ​​assembly 2 and a side snap-fit ​​assembly disposed on the upper part of the sill plate body. The side snap-fit ​​assembly includes a left side connecting snap-fit ​​assembly 3 and a right side connecting snap-fit ​​assembly 4.
