Embodiment Construction

[0012] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0013] like figure 1 and figure 2 As shown, the present invention is a connection structure between a rear bumper and a rear apron of an automobile, mainly consisting of a rear bumper 1, a rear apron 2, bolts 3 and blind rivet nuts 4. Wherein, the rear apron 2 is provided with a bottom hole 21, and the blind rivet nut 4 is passed through the bottom hole 21 of the rear apron 2, and the first annular surface 41 of the blind rivet 4 head and the second ring surface 41 formed after installation are changed. The annular surface 42 clamps and closes the bottom hole 21, thereby fixing the blind rivet nut 4 on the rear skirt 2, and also seals the gap between the blind rivet 4 and the rear skirt 2, so that rainwater cannot pass through the gap between the two. into the luggage compartment. After the bolt 3 passes through the rear bumper 1 and the rivet nut 4, conn...

Abstract

The invention discloses a connecting structure of a rear bumper and a rear apron board of an automobile. The connecting structure comprises the rear bumper (1) which is connected with the rear apron board (2) through a bolt (3). The invention is characterized in that a pull rivet nut (4) is arranged on the rear apron board (2), the bolt (3) penetrates through the rear bumper (1) and the pull rivet nut (4) and then is connected with the rear bumper (1) and the rear apron board (2), and fluid sealant is filled between the threaded fit surface of the bolt (3) and the pull rivet nut (4). The connecting structure can effectively prevent rain from flowing into a trunk from the connecting bolt holes of the rear bumper and the rear apron board and has the advantages that the bolt hole can be produced conveniently and fast, the efficiency is high, and the appearance is attractive.

Description

technical field [0001] The invention relates to an automobile rear bumper, more specifically, relates to a connection structure between an automobile rear bumper and a rear skirt. Background technique [0002] At present, the rear bumper of the automobile is connected with the rear apron by bolts, and the rear apron is located at the rear of the trunk and is one of the enclosing parts forming the trunk. The connection between the rear bumper and the rear apron is that bolt holes are provided on the rear bumper and the rear apron, and projection welding nuts are welded on the back of the rear apron opposite the bolt holes, and the rear bumper is lapped. On the rear apron, the bolts pass through the rear bumper, rear apron and projection welding nuts sequentially from top to bottom to connect the rear bumper and the rear apron. Because there are gaps between the bolts and the through holes of the rear bumper and the rear apron, rainwater can easily enter the inner cavity of t...
