[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0023] Referring to Figure 1 and Figure 2 An embodiment provided by the present invention: A reinforced automotive muffler includes a bracket 1. The bracket 1 can connect two fixing blocks 2. Both the left and right sides of the front part of the bracket 1 are fixedly connected with fixing blocks 2. The two fixing blocks 2 are used to connect a first sliding rod 3. The adjacent sides of the two fixing blocks 2 are fixedly connected with a first sliding rod 3. The first sliding rod 3 provides a sliding space for two sliders 4. The first sliding rod 3 is made of stainless steel, and stainless steel can be more wear-resistant. The outer circumference of the first sliding rod 3 is slidably connected with two sliders 4. The two sliders 4 can squeeze a first spring 5 to contract. A first spring 5 is sleeved in the middle of the first sliding rod 3. The first spring 5 can contract to absorb vibration. The left and right ends of the first spring 5 are respectively fixedly connected to the adjacent sides of the two sliders 4. A second sliding rod 6 is slidably connected inside each of the two fixing blocks 2. The two second sliding rods 6 can fix a support plate 7. The upper ends of the two second sliding rods 6 are fixedly connected with a support plate 7. The support plate 7 fixed to the bottom of the vehicle can provide fixed support for the whole device. Two connecting rods 8 are rotatably connected to the middle of the lower part of the support plate 7. The two connecting rods 8 can push the two sliders 4 to slide. The lower ends of the two connecting rods 8 are respectively rotatably connected to the inside of the two sliders 4. A limiting plate 9 is fixedly connected to the lower end of each of the two fixing blocks 2. The two limiting plates 9 can prevent two second springs 10 from slipping off. A second spring 10 is fixedly sleeved on the outer circumference of the lower part of each of the two second sliding rods 6. The two second springs 10 can absorb vibration by contracting. The two fixing blocks 2 respectively abut against the upper ends of the two second springs 10. A reinforcing component is arranged inside the bracket 1 to reinforce the structural strength of the muffler.
[0024] Referring to Figure 1 and Figure 3, the reinforcement component includes a muffler outer shell 11. The muffler outer shell 11 can protect the muffler inner shell 12 from physical friction loss. The muffler outer shell 11 is made of aluminum alloy, which has a light mass and strong structural strength. An anti-slip pad is provided on the outer periphery of the muffler outer shell 11, which can prevent the muffler outer shell 11 from slipping. The muffler outer shell 11 is fixedly connected to the inner wall of the bracket 1. The muffler inner shell 12 is fixedly connected inside the muffler outer shell 11. The muffler inner shell 12 can provide a certain noise reduction treatment ability and withstand the high heat of the exhaust gas. The muffler inner shell 12 is made of fiberglass fabric, which has strong high-temperature resistance and chemical stability, and also has a certain sound absorption effect. A bellows 13 is fixedly connected to the right end of the muffler outer shell 11. The bellows 13 can bend and buffer the displacement of the equipment after being vibrated. The right end of the bellows 13 is fixedly connected to a flange joint 14, and the flange joint 14 provides the connection support between the equipment and the automobile exhaust port. The diameters of the two annular fixing frames of the bracket 1 are the same, and the diameter of the two annular fixing frames is the same as the outer diameter of the muffler outer shell 11. The center of gravity of the muffler outer shell 11 is located at the center of the bracket 1. The bracket 1 can firmly fix the muffler outer shell 11 and prevent the center of gravity of the muffler outer shell 11 from swinging.
[0025] Working principle: The support plate 7 is fixedly connected to the bottom of the automobile. The equipment is installed by installing the flange joint 14 at the position of the automobile exhaust hole. The muffler outer shell 11 can protect the muffler inner shell 12 from physical friction loss. When the automobile is running, the exhaust gas will enter the inside of the muffler inner shell 12 through the bellows 13. The noise of the automobile exhaust gas will be reduced after passing through the treatment of the muffler inner shell 12. When the automobile is running, it will cause the muffler outer shell 11 to shake. When the muffler outer shell 11 shakes, the bellows 13 will be affected by the displacement through the displacement compensation device. And when the muffler outer shell 11 shakes, the bracket 1 will be driven by the muffler outer shell 11 to shake. The bracket 1 drives the two fixing blocks 2 and the first sliding rod 3 to shake. Thus, the two fixing blocks 2 will squeeze the two second springs 10 to contract. When the two sliders 4 descend, the two connecting rods 8 will pull the two sliders 4 to slide close to each other. The two sliders 4 squeeze the first spring 5 to contract. The contraction of the two second springs 10 and the first spring 5 is used to buffer the vibration received by the muffler outer shell 11. The muffler inner shell 12 can provide noise reduction treatment ability and withstand the high heat of the exhaust gas.
[0026] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
