Description
Technical Field
The utility model relates to the technical field of automobiles, in particular to a vehicle body rear structure.
Background
In order to reduce wind resistance, automobile manufacturers generally design the automobile body to be relatively flat, namely, reduce the height and the size of the automobile body, and in order to ensure the space requirement of the passenger cabin, only the size of the automobile body structure is usually sacrificed, so that the torsional rigidity and the bending rigidity of the white automobile body are generally reduced.
The body rear structure, in particular the parcel shelf and the body rear side wall, is a critical area affecting the torsional rigidity and bending rigidity of the body-in-white. Under traditional structural style, often increase the strengthening rib in order to promote white automobile body torsional rigidity and bending rigidity on automobile body rear portion side wall namely C post inner panel face, this kind of mode not only makes the load of automobile body rear portion side wall increase, and the cost also will greatly increased.
Disclosure of Invention
The utility model provides a vehicle body rear structure, which aims to improve the structural strength between a wrapping frame and a C column inner plate, in particular to the torsion resistance and bending resistance of a rear windshield frame.
In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides a car body rear portion structure, the both ends limit is welded with the inboard face of C post inner panel about the parcel frame, and the side wall strengthening boundary beam has been arranged from front to back to the higher authority of C post inner panel, its characterized in that: the left end and the right end of the wrapping frame are connected with the reinforcing side beams of the side wall through the rib plate supports which are vertically arranged.
In the scheme, in order to ensure that the parcel frame can stably support, both ends limit and the inboard face welding of C post inner panel about the parcel frame. Under the prerequisite that C post inner panel and parcel frame supported each other, have vertical arrangement's gusset to support between the left and right sides both ends and the side wall reinforcing boundary beam of parcel frame to be connected, the gusset has strengthened the support to C post inner panel and the side wall reinforcing boundary beam of arranging in the upside of C post inner panel from the front to the back again, is showing the anti torsion of parcel frame and C post inner panel at the promotion car body rear portion.

Fig. 1 and 2 are schematic structural views of the present utility model.
Detailed Description
As shown in fig. 1 and 2, in a vehicle body rear structure, left and right end edges of a wrapping frame 10 are welded with an inner side plate surface of a C pillar inner plate 20, a side wall reinforcing side beam 30 is arranged on the upper edge of the C pillar inner plate 20 from front to back, and vertically arranged rib plates 40 are supported and connected between the left and right end edges of the wrapping frame 10 and the side wall reinforcing side beam 30.
In the above scheme, the left end edge and the right end edge of the wrapping frame 10 are welded with the inner side plate surface of the C-pillar inner plate 20 integrally, the connection stability between the wrapping frame 10 and the C-pillar inner plate 20 is improved, the side wall reinforcing side beam 30 is arranged on the upper edge of the C-pillar inner plate 20 from front to back to improve the structural strength of the C-pillar inner plate, the rib plates 40 are vertically arranged between the left end and the right end of the wrapping frame 10 and the side wall reinforcing side beam 30 and are in supporting connection with each other, and the connection stability of the corner connection part between the wrapping frame 10 and the C-pillar inner plate 20 is improved.
In order to ensure that the rib plate 40 and the side wall reinforcing side beam 30 are stable, the upper edge profile of the rib plate 40 and the trend of the side wall reinforcing side beam 30 are arranged in a parallel and aligned manner, in other words, the upper edge profile of the rib plate 40 is matched and attached with the profile of the lower plate surface of the side wall reinforcing side beam 30, and the supporting part is an end area of the rear end section of the side wall reinforcing side beam 30.
Further, a flat plate 41 is arranged below the rib plate 40, the rib plate 40 and the flat plate 41 are in an angular plate shape with an integral structure, and the flat plate 41 and the wrapping frame 10 are attached and connected into a whole. The gusset 40 and the flat plate 41 are in an angular plate shape, reliable connection of the gusset 40 and the wrapping frame 10 is achieved, the structural strength of the gusset 40 and the flat plate 41 is enhanced due to the integral structural design of the gusset 40 and the flat plate 41, the flat plate 41 and the wrapping frame 10 are integrally bonded, support is provided for the gusset 40 again, and connection reliability between the wrapping frame 10 and the gusset 40 and the side wall reinforcing side beam 30 is improved.
The flat plate 41 is a square annular plate, and the through hole 411 in the middle of the flat plate is opposite to the hole position of the back door hinge mounting seat on the wrapping frame 10. The flat plate 41 is of square annular design and is simple in structure. And the through hole 411 in the middle is opposite to the hole site of the back door hinge mounting seat on the wrapping frame 10, so that the structural strength of the back door hinge mounting seat on the wrapping frame 10 is enhanced, and convenience is provided for the subsequent wiring harness arrangement of the whole vehicle.
The rear end of the rib plate 40 extends to the joint of the rear end of the side wall reinforcing side beam 30 and the rear side beam 11 of the wrapping frame 10.
To further enhance the structural strength of the C-pillar inner panel 20, the rear end of the C-pillar inner panel 20 has reinforcing ribs 21 arranged in the up-down direction.
Preferably, the reinforcing ribs 21 are integrally punched and formed ribs of the C-pillar inner plate 20, so that additional accessories are prevented from being added on the surface of the C-pillar inner plate 20, and the production cost is saved.
The upper ends of the reinforcing ribs 21 extend to the joint between the rear ends of the side wall reinforcing side beams 30 and the rear side beams 11 of the wrapping frame 10.
In view of the fact that the upper ends of the reinforcing ribs 21 and the rear ends of the rib plates 40 extend to the joint of the rear ends of the side wall reinforcing side beams 30 and the rear side beams 11 of the wrapping frame 10, the strength of the joint of the rear ends of the side wall reinforcing side beams 30 and the rear side beams 11 of the wrapping frame 10, which is weak in original structure, is remarkably improved.
