Description

Technical Field

[0001] The utility model relates to the technical field of automobile interior decoration parts, in particular to an automobile B-pillar guard plate. Background Art

[0002] As the core component supporting the car, the automobile pillar has the following functions: the interior shape of the car gives people a sense of beauty; the use of specific materials to improve riding comfort; the use of specific installation structures to improve driving safety. In the installation arrangement of the pillars in the direction of the car body, they can also be divided into A-pillars, B-pillars and C-pillars according to the front, middle and rear. The B-pillar guard installed on the outer side of the B-pillar sheet metal is generally arranged with a seat belt assembly inside, resulting in a more complex structure of the B-pillar guard. In traditional technology, the B-pillar guard usually includes the following two structural schemes:

[0003] (1) A structure for avoiding the seat belt fixing point is set at the bottom of the B-pillar guard plate. That is, when the B-pillar guard plate is assembled to the inner side of the B-pillar sheet metal, the seat belt fixing point is directly fixed to the lower end of the outer side of the B-pillar guard plate. This will expose the seat belt fixing point, occupy external space and have poor aesthetics.

[0004] (2) A clamping hole corresponding to the lower fixing point of the seat belt is opened at the lower end of the B-pillar guard plate. After the seat belt assembly is installed in place, the clamping hole at the lower end of the B-pillar guard plate is buckled and sealed with a cover plate. Since the B-pillar guard plate and the cover plate are designed as two components, the two components need to be molded and processed separately. The manufacturing process is relatively cumbersome and the cost is high, which is not suitable for mass production.
