Description
Technical Field
The invention belongs to the technical field of automobile rear door installation, and relates to a C-pillar hinge installation structure of a split door.
Background
The traditional front and rear door opening mode of the automobile is a forward opening mode, and the rear door installation mode is connected with the B column through a hinge. With the diversified development of automobiles, the automobile with front and rear doors split is derived, and the rear door mounting mode is connected with the C column through a hinge. The change of the opening mode of the car door changes the traditional opening mode of the car door from the appearance, and the model is novel; in practical application, the convenience of getting on and off the vehicle and the space for getting in and out the vehicle door of the rear-row passengers of the side-by-side combination type vehicle are greatly improved.
At present, few vehicle types in China are in a side-by-side door opening mode, the C-column position is limited by the Z-direction space of a rear wheel cover, the upper hinge span and the lower hinge span of a rear door are limited, and the vehicle body side hinge mounting structure cannot meet the rigidity of the hinge mounting position according to the traditional structure (a C-column hinge reinforcing plate and a hinge mounting nut plate).
There are two structural forms in the prior art:
firstly, the hinge reinforcing part is added at the position of the C-pillar hinge reinforcing plate or the material thickness of the hinge reinforcing plate and the nut plate is increased, so that the weight and the cost of a vehicle body are greatly increased, and meanwhile, the vertical rigidity of the C-pillar is not obviously improved.
And the C column reinforcing plate is divided into an upper section structure and a lower section structure, and aluminum profiles are added in the lower section area of the C column reinforcing plate connected with the rear door hinge for fixing the rear door hinge. Due to the limitation of the external shape of the vehicle body, the section structure can not be connected with the upper part of the side wall rear door frame and the rear doorsill, the section needs to be connected at the position below the edge of the C column reinforcing plate window, and the rear door hinge fixing structure is formed through the lap joint transition of the upper section and the lower section of the C column reinforcing plate. The upper section and the lower section of the C-column reinforcing plate are of welded structures, and the section bar of the hinge fixing part is connected with the lower section of the C-column reinforcing plate by a riveting process. The segmented structure of the C-column reinforcing plate has the disadvantages that the overall strength of the C-column is insufficient, and the sectional material structure only ensures the local strength of a hinge mounting area, so that the strength of the whole vehicle frame is insufficient; because the section bar is of an extruded aluminum structure, the installation molded surface cannot adapt to the change of the C column model, the large-area change of the side wall outer plate between the upper hinge and the lower hinge of the C column is smooth, and the model has no bright points.
Disclosure of Invention
