Hatchback vehicle and rear cover assembly thereof

Abstract

The invention discloses a hatchback vehicle and a rear cover assembly thereof. The rear cover assembly comprises an inner plate, an outer plate and a cover lock mounting plate, wherein the edges of the inner plate and the outer plate are provided with edge covering structures, and the inner plate and the outer plate are fixedly adhered at the edge covering structures through sealing stripes; the cover lock mounting plate comprises a main body unit and an extension unit, the main body unit is welded to the inner plate, and the extension unit is welded to the outer plate. Therefore, besides the traditional edge covering and adhering structures, the rear cover assembly also obtains the welding structures on the cover lock mounting plate; the cover lock mounting plate achieves indirect connection between the inner plate and the outer plate and improves the connecting structure between the inner plate and the outer plate, thereby reducing the risk of displacement between the inner plate and the outer plate, enhancing the strength of the rear cover assembly and further ensuring the traveling safety of a vehicle.

Description

technical field [0001] The invention relates to the technical field of vehicle engineering, in particular to a rear cover assembly for hatchback type vehicles. The present invention also relates to a hatchback vehicle comprising the above-mentioned rear cover assembly. Background technique [0002] The back cover assembly is one of the very important components of the car. It has the dual functions of supporting protection and appearance performance. In order to ensure the appearance of the back cover, the The support and protection of the cover requires the strength and durability of the back cover. [0003] Such as figure 1 and figure 2 As shown, the rear cover assembly of hatchback doors such as hatchbacks and sedans currently includes an inner panel 11, an outer panel 12, a rear cover lock mounting plate 14 for installing a rear cover lock 13, a rear bumper 15, License plate 16, etc., wherein, the inner panel 11 and the outer panel 12 are mostly fixed by hemming, an...

AI Technical Summary

Problems solved by technology

[0003] like figure 1 and figure 2 As shown, the rear cover assembly of hatchback doors such as hatchbacks and sedans currently includes an inner panel 11, an outer panel 12, a rear cover lock mounting plate 14 for installing a rear cover lock 13, a rear bumper 15, License plate 16, etc., wherein, the inner panel 11 and the outer panel 12 are mostly fixed by hemming, and at the position of the rear cover and the rear bumper of the car, the inner panel 11 and the outer panel 12 rely on sheet metal hemming and bonding after hemming The sealant is fixed, and the inner panel 11 is also equipped with components such as the rear cover lock 13 and the rear cover buffer block. The acting force happens to be similar to the direction of the inner and outer sheet metal wrapping, which is easy to cause misalignment of the inner and outer panels. If the acting force is greater than the friction force after the sheet metal wrapping and the connection force of the coated sealant, it will lead to cracking of the sealant and damage to the inside and outside. Plate misalignment creates risks such as insufficient back cover strength
