Description

Upper and lower guard plate lap joint structure of center pillar

Technical Field

The utility model belongs to the technical field of automobile parts, concretely relates to backplate overlap joint structure about well stand.

Background

The requirement for the clearance surface difference of the automobile product belongs to the field of geometric dimension; within the definition of product function, it is classified into aesthetic categories. Objectively, the method directly influences the perception quality of the user on the whole vehicle. The guarantee of the clearance surface difference depends on the product size conformity of the related interface and also depends on the skill of the product positioning structure.

The automobile middle upright post guard board (or called B post decorative board) is positioned in the middle of the front and rear seats and on the inner side of the side wall of the automobile body, and is generally divided into an upper section and a lower section, namely an upper section B and a lower section B for short, and plays a role in shielding a side wall metal plate, a front-row safety belt retractor and the like. The upper section and the lower section are in a butt joint mode.

The problems with loading these two products are: the existing structure (in the lapping area) only has a positioning structure with a positioning pin hole matched with a positioning bayonet pin, and only can ensure that the surface difference of the front side of the butting area accords with the clearance surface difference definition, but the surface difference of the side surface is not structurally controlled, so that the surface difference requirement is difficult to ensure. From the viewpoint of product technology, the side face is a more easily deformable area, i.e. the difference in surface is easily out of definition.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a backplate overlap joint structure about well stand exists exactly in order to solve the not enough of above-mentioned background art existence.

The utility model adopts the technical proposal that: the utility model provides a backplate overlap joint structure about well stand, includes plaque, B post under the B post, plaque overlap joint under plaque, the B post on the B post, plaque side inboard is equipped with limit structure under the B post, plaque side is equipped with and is used for limit structure laminating and limiting plate on the B post, limit structure and limiting plate cooperation will plaque, B post under the B post are spacing in the regional side of overlap joint.

In a further preferred configuration, the stopper plate is inclined inward of the B-pillar upper garnish with respect to the B-pillar upper garnish side surface.

In a further preferred structure, the limiting structure is one or more hollow box-shaped structures protruding from the inner side of the side edge of the B-pillar lower decorative plate.

In a further preferred structure, a supporting strip is arranged on the side face of the B-column upper decorative plate and is positioned between the side face edge of the B-column upper decorative plate and the side face edge of the B-column lower decorative plate.

In a further preferable structure, the edge of the B-column upper decorative plate where the supporting bars are located and the edge of the B-column upper decorative plate body are of a stepped structure.

The utility model has the advantages that: by additionally arranging the limiting structure, full-profile control of the upper and lower decorating parts of the middle upright post in the surface difference of the lap joint area is realized.

Detailed Description

The invention will be further described in detail with reference to the drawings and the following detailed description, which are provided for the purpose of clearly understanding the invention and are not intended to limit the invention.

As shown in fig. 1-4, in the existing structure, only the positioning structure with the positioning pin hole 1 and the positioning bayonet 2 matched in the lapping area 3 of the upper decorative plate and the lower decorative plate of the B column can ensure that the surface difference of the front surface 4 of the butt joint area only meets the clearance surface difference definition, and the surface difference of the side surface 5 has no structural control, so that the surface difference requirement is difficult to ensure. From the viewpoint of product technology, the side face is a more easily deformable area, i.e. the difference in surface is easily out of definition.

As shown in fig. 5-6, the utility model discloses a plaque under plaque, the B post on the B post, plaque overlap joint under plaque, the B post on the B post, plaque side border inboard is equipped with limit structure 6 under the B post, plaque side is equipped with and is used for limit structure laminating and limiting plate 8 on the B post, limit structure 6 cooperates with limiting plate 8 will plaque, plaque are spacing in the overlap joint region side under plaque, the B post on the B post. The limiting plate 8 is inclined towards the inner side of the B-column upper decoration plate relative to the side surface of the B-column upper decoration plate. In the preferred embodiment of the utility model, the limit structure 6 is one or more hollow box-shaped structures protruding from the inner side of the side edge of the B-pillar lower decorative plate,

as shown in fig. 6-8, a support strip 7 is provided on the side of the B-pillar upper trim panel, and the support strip 7 is located between the side edge of the B-pillar upper trim panel and the side edge of the B-pillar lower trim panel. The edge of the B-pillar upper decorative plate where the supporting strips 7 are located and the edge of the B-pillar upper decorative plate body are of a stepped structure.

As shown in fig. 8, the limiting structure 6 is limited by the limiting plate 8, and the supporting strip 7 limits the profile of the B-pillar lower trim, so that the B-pillar lower trim cannot move in the X-direction relative to the B-pillar upper trim. That is, the B-pillar lower trim side 10 cannot move in the X-direction with respect to the B-pillar upper trim side 9. The fact that the B-pillar lower trim side 10 cannot move in the X + direction with respect to the B-pillar upper trim side 9 is achieved by the outer press seal 11 shown in fig. 9, and is not described here because of the original mechanism.

Those not described in detail in this specification are within the skill of the art.
