Embodiment Construction

[0016] Below in conjunction with accompanying drawing and specific embodiment, the present invention is described in further detail;

[0017] See figure 1 , figure 2 , the automobile side wall inner panel of the present invention, the plate body 1 is approximately rectangular, the front part of the plate body 1 is a C-pillar 2, and the lower end of the C-pillar 2 is provided with a groove 2-1, which can improve the torsional strength of the vehicle. The rear part of the plate body 1 is the D-pillar 3, and the middle part 3-1 of the D-pillar is in the shape of a trumpet, which not only plays a transitional role, but also reduces stress concentration. The middle and upper part of the plate body is the rear side window frame 6, which is in an inverted trapezoidal shape, and its lower part is narrower near the middle part 3-1 of the D-pillar, which is an inward bevel, which can avoid cracking of the side wall outer panel. A plurality of weight-reducing holes 4 are evenly distri...

Abstract

The invention discloses an automobile side wall internal plate. A plate body thereof is a rectangular stamping component and the front end of the plate body is a C post while the rear end thereof is a D post. The middle upper part of the plate body is provided with a rear side window frame and the middle lower part of the plate body is provided with lightening holes. A plurality of lightening holes are distributed in the middle lower part of the plate body and a support leg slantwise extending to the outside is left on the edge of the lightening hole. After the installation, the support leg supports between a right side wall internal plate and a right side wall external plate. The support leg is provided with a glue storage groove of which two ends take the shape of a closed arc, and the support leg is also provided with a strengthening rib. The position which is close to the middle position of the D post and at the underside of the rear side window frame is an inward oblique angle so as to cause the D post to take the shape of a trumpet. The automobile side wall internal plate of the invention has simple structure and comparatively high strength and can overcome the defects of insufficient strength and support, easy deformation of the external plate and the influence on the service life of an automobile body.

Description

technical field [0001] The invention relates to an automobile body structure, in particular to an automobile side wall inner panel structure. Background technique [0002] At present, the commonly used inner panels of automobile side panels mainly include C-pillars, D-pillars, rear side window frames, and weight-reducing holes. The main defects are that the strength is insufficient and the support is not enough. , affecting the service life of the vehicle body. Utility model content [0003] In order to overcome the defects in the prior art, the present invention provides a side wall inner panel with simple structure and high strength. [0004] The panel body of the automobile side wall inner panel of the present invention is a rectangular stamping part, the front end of the panel body is a C-pillar, the rear end is a D-pillar, the middle and upper part of the panel body has a rear side window frame, and the middle and lower part of the panel body is distributed with weig...
