Car runk assembly

Abstract

The invention discloses a car trunk assembly, which comprises an outer plate and an inner plate with a gel groove, and is characterized in that: a left lower sunken table, a left upper sunken table, a right upper sunken table and a right lower sunken are arranged in a registration mark plate mounting region at the lower part of the outer plate, and a left flanging and a right flanging which are in a square shape and eudipleural are arranged on the inner plate corresponding to the registration mark plate mounting region; the gel groove at the upper part of the inner plate is injected with swelling gel, and the outer plate and the inner plate are overlapped and are connected together through the swelling gel; the left flanging at the lower part of the inner plate and the left upper sunken table and the left lower sunken table at the lower part of the outer plate are welded together, and the right flanging at the lower part of the inner plate and the right upper sunken table and the right lower sunken table at the lower part of the outer plate are welded together; and the outer plate is connected with the inner plate through a buckling wrapping edge. The invention has the following advantages: the inner plate and the outer plate of the trunk are more firmly connected into a whole, thereby increasing the stiffness and strength of the trunk assembly, and being favorable for preventing the trunk assembly from shaking.

Description

technical field [0001] The invention belongs to automobile parts, in particular to a car trunk assembly. Background technique [0002] At present, a common car trunk includes a trunk outer panel and a trunk inner panel, and the outer panel and the inner panel are connected by buckling and edging. Due to the high frequency of opening and closing of the trunk and the large impact of switching the trunk, the trunk assembly is required to have good rigidity and strength. The lapping of the inner and outer panels of the suitcase is mainly done by making a bead structure on the inner panel of the suitcase, and then extruding expansion glue in the bead groove to connect with the outer panel of the suitcase, so as to strengthen the rigidity and strength of the suitcase assembly. However, due to the limitation of space and structure, this reinforced structure with ribs and expansion rubber can only be arranged on the upper part of the suitcase, and the lower part of the suitcase wil...
