Embodiment 1

[0038] As shown in the accompanying drawings, a flexible fixing bracket assembly for an automobile exhaust tailpipe includes an exhaust tailpipe hoop 1 and an exhaust tailpipe bracket 2, and the automobile exhaust tail 3 is stuck in the exhaust tailpipe hoop 1 , and then hung on the exhaust tailpipe bracket 2 by the exhaust tailpipe hoop 1; a flexible connector 4 is arranged between the exhaust tailpipe hoop 1 and the exhaust tailpipe bracket 2, and the exhaust tailpipe hugs The hoop 1 is suspended on the exhaust tailpipe bracket 2 through the flexible connector 4, and the exhaust tailpipe bracket 2 is fixed on the vehicle frame 6 through the fastener 5, so that the exhaust tailpipe hoop 1 and the exhaust tailpipe The pipe support 2 is in a flexible connection state, forming a flexible installation.

[0039] Wherein, the exhaust tailpipe bracket 2 is a combined metal component, including an "L"-shaped connecting plate 7, and a bracket hanging rod 8 bent into three 90-degree an...

Embodiment 2

[0046] Embodiment 2 has basically the same structure as Embodiment 1. It is a flexible fixing bracket assembly for an automobile exhaust tailpipe, including an exhaust tailpipe hoop and an exhaust tailpipe bracket. Inside the hoop, the exhaust tailpipe hoop is hung on the exhaust tailpipe bracket. There is a flexible connector between the exhaust tailpipe hoop and the exhaust tailpipe bracket. The exhaust tailpipe hoop is The flexible connector is suspended on the exhaust tailpipe bracket, so that the exhaust tailpipe hoop and the exhaust tailpipe bracket are in a flexible connection state, forming a flexible installation.

[0047] It’s just that the exhaust tailpipe support is fixed on the vehicle frame by welding, and the flexible connector is a composite member of metal and elastomer; the outer part of the composite member is a metal material shell, and The elastic body is fixed, and there are two composite connection holes in the middle of the elastic body. One of the comp...

Embodiment 3

[0049] The structure of the third embodiment is basically the same as that of the first embodiment. It is a flexible fixing bracket assembly for the exhaust tailpipe of an automobile, including an exhaust tailpipe hoop and an exhaust tailpipe bracket. Inside the hoop, the exhaust tailpipe hoop is then hung on the exhaust tailpipe bracket. The hoop is suspended on the exhaust tailpipe bracket through a flexible connector, so that the exhaust tailpipe hoop and the exhaust tailpipe bracket are in a flexible connection state, forming a flexible installation.

[0050] It is just that the shape of the flexible connector is rectangular, and an elastic body is wrapped in the rectangular shell. The elastic body is a two-body structure and is also a square body. There is a composite connecting hole on each square body. The exhaust tailpipe support can be fixed on the vehicle frame by welding, or fixed on the vehicle frame by fasteners.

Abstract

The invention relates to an automotive tail pipe fixing method and a flexible fixed support component. An automotive tail pipe is flexibly connected with a fixed mounting support through a flexible mounting support, the vibration energy of the tail pipe is effectively released through the flexible mounting support during working, the connection of the tail pipe and a silencer is further protected, and tearing is effectively prevented. The flexible fixed support component comprises a tail pipe hoop and a tail pipe support. The automotive tail pipe is clamped in the tail pipe hoop, and then the tail pipe hoop is hung on the tail pipe support. The flexible fixed support component is characterized in that a flexible connecting piece is arranged between the tail pipe hoop and the tail pipe support; the tail pipe hoop is hung on the tail pipe support through the flexible connecting piece, so that the tail pipe hoop and the tail pipe support are in a flexible connection state, and finally the flexible mounting is formed.

Description

technical field [0001] The invention relates to a method and device for installing and fixing automobile parts, in particular to a method for fixing an exhaust tailpipe of a new energy passenger car and a fixing bracket assembly, belonging to the technical field of automobile manufacturing. Background technique: [0002] The exhaust of a car is discharged through the exhaust pipe, so the exhaust system is one of the important assemblies on a modern car, which plays a very important role in purifying exhaust emissions and absorbing engine exhaust excitation noise. The fixing bracket for fixing the exhaust tail pipe of the automobile is used as the load-bearing and vibration-isolation part of the exhaust system, and plays the role of suspending the exhaust system and isolating the excitation from the exhaust system from the body. With the widespread adoption of lightweight body design, front-mounted engine (i.e. front-wheel drive) and poorly balanced four-cylinder engines, th...
