Technical Field

[0001] This utility model relates to the field of automotive technology, and in particular to an automotive rear muffler hook assembly and an automotive. Background Technology

[0002] Hooks connect the vehicle's exhaust system to the body. Existing hooks are generally only the hook part, and the hook is directly connected to the body using CO2 shielded welding. This method results in insufficient connection strength between the hook and the body, leading to cracking during road tests. Furthermore, when this connection structure is used in off-road vehicles or other vehicles that frequently operate under harsh conditions, insufficient rigidity can cause excessive displacement of the exhaust system, increasing noise and weakening durability and NVH (noise, vibration, and harshness) performance.

[0003] Therefore, it is necessary to improve the structure of the rear muffler hook in the existing technology, which can increase the structural strength of the hook, reduce the displacement of the exhaust system under bad road conditions, reduce noise, and increase the service life of the hook.

Figure 1-5As shown: This embodiment of the automotive rear muffler hook assembly includes a hook assembly and a mounting plate 2. The hook assembly includes a hook 3 and a reinforcing member 1 for reinforcing the hook 3. The hook assembly is fixedly installed on the vehicle body via the mounting plate 2. The hook 3 and the reinforcing member 1 can both be fixedly connected to the mounting plate 2, or the hook 3 can be fixedly connected to the mounting plate 2 while the corresponding reinforcing member 1 is directly fixed to the vehicle body and integrated with the hook 3 to reinforce it. Alternatively, the reinforcing member 1 can be fixedly connected to the mounting plate 2 while the corresponding hook 3 is directly fixedly connected to the vehicle body and integrated with the reinforcing member 1. The reinforcing member 1 and the hook 3 can be fixed by welding or bolting. Preferably, the hook 3 and the reinforcing member 1 are simultaneously fixedly connected to the mounting plate 2, which saves installation space and reduces the probability of interference with other vehicle body components. The hook 3 is generally used to connect to the rear muffler. The hanger 4 on the device 5 is connected. The hanger 4 is generally made of rubber. The hook 3 is equipped with an anti-drop part to achieve a limiting connection with the hanger 4, thereby supporting the rear muffler 5. The reinforcing part 1 can be a reinforcing rod or other structure. By fixing the reinforcing part 1 and the hook 3 together, the structural strength of the hook 3 can be improved, the service life of the hook 3 can be increased, and the displacement of the exhaust system under bad road conditions can be reduced. At the same time, the reinforcing part 1 can also play a certain role in damping the vibration amplitude and reducing noise. The hook assembly is fixedly connected to the vehicle body through the mounting plate 2, which can improve the connection strength between the hook assembly and the vehicle body compared with the existing technology.

[0026] In this embodiment, both the hook 3 and the reinforcing member 1 are fixedly connected to the mounting plate 2, so that the hook assembly is fixedly installed on the vehicle body via the mounting plate 2. The fixed connection and installation of the hook 3 and the reinforcing member 1 to the mounting plate 2 and the vehicle body via the mounting plate 2 saves installation space and reduces the probability of interference between the hook 3 or the reinforcing member 1 and other components of the vehicle body.

[0027] In this embodiment, the hook 3 includes an installation section I 301, a connecting section I 302, and a suspension section 304.

The suspension section 304 is connected to the rear muffler 5 of the vehicle via a lug 4. The hook 3 is a structural component formed by spatially bending a cylindrical steel bar. It can be a hollow tubular structure or a cylindrical structure. One end of the installation section I 301 faces upward (relative to...). Figure 1 (Up and down direction) bends and extends to form connecting segment I302, with one end of connecting end I pointing to the right (relative to) Figure 1The suspension section 304 is formed by bending and extending in the left and right directions. When in use, the suspension section 304 is connected to the lug 4 on the rear muffler 5. The lug 4 is generally connected to the connector set on the rear muffler 5. The structure of the lug 4 is an application of existing technology, which will not be described in detail here. Thus, the hook 3 supports the rear muffler 5.

[0028] In this embodiment, the reinforcing member 1 includes a mounting section II 101 and a connecting section II 102. The mounting section II 101 is fixedly connected to the mounting plate 2, and the connecting section II 102 is fixedly integrated with the connecting section I 302. One end of the mounting section II 101 faces upward (relative to...). Figure 1 The connecting section II 102 is formed by bending and extending in the vertical direction. The connecting section II 102 is welded to the connecting section I 302 as a whole (that is, the outer wall of the connecting section II 102 is welded to the outer wall of the connecting section I 302), thereby providing support for the hook 3 and improving the structural strength of the hook 3.

[0029] In this embodiment, the mounting plate 2 is provided with mounting groove I 208 and mounting groove II 209. Mounting segment I 301 is mounted in mounting groove I 208, and mounting groove I 208 partially encloses mounting segment I 301.

Mounting segment I 301 is welded to mounting groove I 208 and can be partially enclosed by mounting groove I 208, thereby increasing the contact area between mounting segment I 301 and mounting groove I 208 and improving the connection strength. Mounting segment II 101 is welded to mounting groove II 209 and can be partially enclosed by mounting groove II 209, thereby increasing the contact area between mounting segment II 101 and mounting groove II 209 and improving the connection strength between mounting segment II 101 and mounting plate 2.

[0030] In this embodiment, the mounting plate 2 includes a mounting surface I 201 and a mounting surface II 202. One end of the mounting surface II 202 is bent downwards to form the mounting surface I 201. Mounting grooves I 208 and II 209 are provided on the mounting surface II 202. One end of the mounting groove I 208 communicates with one end of the mounting groove II 209 and forms an included angle, the angle of which is 100° to 115°.
