Description

Technical Field

[0001] This utility model relates to automotive interior parts, and in particular to an assembly of a lower guard plate for the left B-pillar of an automobile. Background Technology

[0002] As an important decorative component in automobiles, the pillar inner panel has very high aesthetic requirements. The B-pillar inner panel, being visible to both front and rear passengers, demands even higher standards. In current automotive technology, for aesthetic purposes, the side flanges of the B-pillar inner panel utilize an inverted structure in the injection mold. This structure creates inward stress, causing the flanges furthest from the mounting point to taper inwards. Since the lower B-pillar inner panel is longer and weaker than other pillar inner panels, this taper is particularly pronounced, severely impacting the appearance and causing instability in its connection with the upper left B-pillar and the vehicle body. Furthermore, the lower left B-pillar inner panel lacks sound-absorbing properties. Utility Model Content

[0003] The purpose of this utility model is to provide an assembly of the lower guard plate of the left B-pillar of a car, which solves the problem of the stable connection between the lower guard plate of the left B-pillar, the upper guard plate of the left B-pillar, and the car body.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a car left B-pillar lower guard plate assembly, including a left B-pillar lower guard plate body and a sound-absorbing cotton body disposed behind the left B-pillar lower guard plate body. The upper end of the left B-pillar lower guard plate body is provided with an upper connecting end structure connected to the left B-pillar upper guard plate body, a bottom connecting end structure disposed at the lower end of the left B-pillar lower guard plate body, and a rear inner clip connecting assembly disposed behind the left B-pillar lower guard plate body. The rear inner clip connecting assembly includes an external fixing assembly, a body edge fixing assembly, and a sound-absorbing cotton body insertion and clipping assembly.

[0005] The external fixing components include an upper left guard plate mounting point, an upper right guard plate mounting point, a lower left guard plate mounting point, and a lower right guard plate mounting point.

[0006] The aforementioned upper connection end structure includes multiple internal insertion holes located on the upper part of the main body of the lower guard plate of the left B-pillar, and an upper component insertion hole group located in the internal insertion holes.

[0007] The bottom connection end structure includes a left extension snap-fit ​​seat located on the left side of the lower end of the main body of the left B-pillar lower guard plate, a left extension snap-fit ​​seat located on the right side of the lower end of the main body of the left B-pillar lower guard plate, a docking groove located in the middle of the lower end of the main body of the left B-pillar lower guard plate, and a limiting hole located at the upper edge of the lower end of the main body of the left B-pillar lower guard plate.

[0008] The beneficial effects of this utility model are as follows: The lower B-pillar guard plate can be securely connected to the upper B-pillar guard plate and the vehicle body, ensuring the connection strength of the B-pillar structure. Furthermore, the precise external structure is suitable for the combined installation of various connecting parts. Sound-insulating cotton is incorporated into the lower B-pillar guard plate body, providing sound insulation for the components.

[0009] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments. Attached Figure Description
