Abstract
The utility model provides a connection structure that car D post and back enclose, including first connecting plate and the second connecting plate that links to each other with first connecting plate welding, the draft angle of the outer panel of first connecting plate and second connecting plate is 15, and the draft angle that the one end of first connecting plate was kept away from to the inner panel of second connecting plate is 5, and is provided with protruding section inwards. The utility model discloses avoid appearing the crackle in the connecting plate forming process, the yield is high, satisfies the D post moreover and encloses the connection demand after with.
Description
Technical Field
The utility model relates to the technical field of automobiles, in particular to a connection structure of a D column and a rear wall of an automobile.
Background
The automobile D column is generally common in SUV and MPV models, is positioned at the direct connection part of a vehicle body rear patch roof and a carriage, and has higher strength and can not have the defects of cracks and the like due to the requirement of a connection structure of the D column and a rear wall. In the prior art, as shown in fig. 1, the connection structure of the D-pillar and the rear wall of the automobile is generally formed integrally, and because the connection structure is slightly complex, cracks or stress concentration is easy to occur during the forming process, and the yield is low.
SUMMERY OF THE UTILITY MODEL
The utility model provides a connection structure of car D post and back enclose avoids appearing the crackle in the connecting plate forming process, and the yield is high, satisfies the connection demand that D post and back enclose moreover.
The technical scheme of the utility model is realized like this: the utility model provides a connection structure that car D post and back enclose, includes first connecting plate and the second connecting plate that links to each other with first connecting plate welding, the draft angle of the outer panel of first connecting plate and second connecting plate is 15, and the draft angle that the one end of first connecting plate was kept away from to the inner panel of second connecting plate is 5, and is provided with protruding section.
Further, the upside that first connecting plate and second connecting plate meet one end all is provided with first punching press hole, and the upside of the first connecting plate and the second connecting plate other end all is provided with second punching press hole.
Furthermore, the first connecting plate is of an integral structure, and the second connecting plate is of an integral structure.
The utility model has the advantages that:
the utility model discloses divide into first connecting plate and second connecting plate with connection structure, both weld and link to each other, namely the connection structure has divided into two times shaping, avoids appearing the crackle in the connecting plate shaping process, and the yield is high, and satisfies the connection demand of D post and back wall; the change of drawing die angle of outer panel and interior plate is favorable to the shaping drawing of patterns of first connecting plate and second connecting plate.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention.
The "upper, inner, outer" and the like of the present invention are relative to the positional relationship shown in fig. 2.
As shown in FIG. 2, a connection structure of a D-pillar and a rear wall of an automobile comprises a first connection plate 1 and a second connection plate 2 connected with the first connection plate 1 in a welding mode, wherein the first connection plate 1 and the second connection plate 2 both comprise an arc-shaped upper plate 3, an outer side plate 8 is arranged on the outer side of the arc-shaped upper plate 3, an inner side plate 9 is arranged on the inner side of the arc-shaped upper plate 3, and the arc-shaped upper plate 3, the outer side plate 8 and the inner side plate 9 are of an integrally formed structure.
The draft angle of the outer side plate 8 of the first connecting plate 1 and the second connecting plate 2 is 15 degrees, the draft angle of the end, far away from the first connecting plate 1, of the inner side plate 9 of the second connecting plate 2 is 5 degrees, an inward protruding section 4 is arranged, and the punching angle of the reference hole is 90 degrees.
The upside that first connecting plate 1 and second connecting plate 2 meet one end all is provided with first punching press hole 5, and the upside of the first connecting plate 1 and the 2 other ends of second connecting plate all is provided with second punching press hole 6.
As shown in fig. 3 and 4, one end of the inner side plate of the connecting structure in the prior art is provided with an inner groove 7, the inner side plate 9 of the present embodiment is provided with a convex section 4 at a position corresponding to the inner groove 7, and the draft angle of the inner side plate 9 of the present embodiment is different from that of the prior art; the draft angle of connection structure outer panel is also different with the outer panel 8 of this embodiment among the prior art, through the change of inner panel and outer panel structure, the shaping drawing of patterns of being convenient for.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
