Technical Field

[0001] The utility model relates to the technical field of automobile manufacturing, in particular to a support structure of a vehicle muffler. Background Art

[0002] The car muffler is an automotive component installed on the exhaust pipe of the car. It can effectively reduce and suppress the noise generated by the combustion exhaust gas discharged from the engine. Most car mufflers are installed on the vehicle chassis through a bracket structure. Since the overall volume of the car muffler is large, in order to prevent the car muffler from being dragged on the ground when the vehicle is driving, the bracket structure of the muffler will not bypass the bottom of the muffler to cover it, but will be set above the muffler to install and fix it at the bottom of the car.

[0003] After working for a long time, the common automobile muffler connection structure is prone to breakage due to natural metal corrosion and vehicle vibration, causing the muffler to lose its fixation. This will cause certain abnormal noises during subsequent vehicle driving and will also have a certain impact on the overall installation stability of the muffler. Utility Model Content

[0031] See also Figure 1-4 The utility model discloses a support structure of a vehicle muffler, comprising a fixing frame 1 connecting the muffler and a vehicle body, and an anti-detachment component 2 also connecting the vehicle body and the muffler.

[0032] Specifically, the fixed frame 1 includes a fixed plate 11 installed on the surface of the vehicle body, and a connecting frame 12 connecting the fixed plate 11 and the muffler. The connecting frame 12 can be a common metal bracket structure and can be connected to the fixed plate 11 by bolts. The fixed plate 11 can also be connected to the vehicle body by bolts.

[0033] The anti-drop assembly 2 includes a fixed docking portion 21 arranged on the surface of the muffler, and a movable docking portion 22 that can be installed on the surface of the fixed plate 11. The fixed docking portion 21 is connected to the movable docking portion 22. When the muffler is connected to the fixed plate 11 through the connecting frame 12, the movable docking portion 22 and the fixed docking portion 21 can only make relative movements in the vertical direction, and the movable docking portion 22 and the fixed docking portion 21 do not provide tension to each other. After the fixed frame 1 is separated from the fixed plate 11, the movable docking portion 22 and the fixed docking portion 21 can still be connected to each other.

[0034] On this basis, the fixed docking portion 21 includes a mounting seat 211 arranged on the surface of the muffler, and a fixing kit 212 arranged on the mounting seat 211, the movable docking portion 22 includes a movable kit 221 that can be docked with the fixing kit 212, a soft connection structure arranged between the movable kit 221 and the fixing kit 212, and a sliding mounting structure 24 that can connect the movable kit 221 with the fixed plate 11, the movable kit 221 and the fixing kit 212 are both tubular structures, the movable kit 221 can extend into the interior of the fixing kit 212, and the movable kit 221 and the fixing kit 212 are connected. The interior of the fixing kit 212 is communicated, and the soft connection structure includes a fixing member 222 arranged inside the fixing kit 212 and the movable kit 221, and a connecting rope 223 connecting the fixing member 222. The fixing member 222 can be a common raised annular structure that can be wrapped around the fixing connecting rope 223. If the connecting frame 12 and the fixing plate 11 are separated, the connection between the muffler and the vehicle body can be continued to be ensured through the connecting rope 223. Since the connecting rope 223 is not subjected to tension during daily vehicle driving, it can maintain a relatively complete working state for a long time, and the possibility of material fatigue is low.

[0035] In order to ensure the smooth installation of the movable docking part 22 and the fixed docking part 21, as shown in the figure, the sliding installation structure 24 includes a sliding plate connected to the movable kit 221, and a slide groove provided on the surface of the fixed plate 11 and adapted to the sliding plate. The surface of the fixed plate 11 is provided with an opening allowing the sliding plate to be inserted from the outside of the fixed plate 11 into the inside of the slide groove. The number of fixed plates 11 can be even, and all fixed plates 11 are evenly distributed at the top position of the muffler. The openings relative to the fixed plate 11 can be arranged relatively, and the number of fixing parts 222 is at least two, and all fixing parts 222 are evenly distributed on the surface of the sliding plate and the mounting seat 211. The design here can ensure convenient installation while also realizing the limitation of the fixed kit 212 and the movable kit 221, ensuring that the force direction thereof is controllable. When the sliding plate enters the slide groove and moves to the end of the slide groove, the movable kit 221 can be vertically inserted into the inside of the fixed kit 212.

[0036] In order to further isolate the connecting rope 223 from the external environment, an isolation rubber cover 23 capable of covering the soft connecting structure is provided between the fixed kit 212 and the movable kit 221. The overall length of the isolation rubber cover 23 and the connecting rope 223 is less than or equal to the sum of the lengths of the movable kit 221 and the fixed kit 212.
