Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of motorcycle mufflers, and in particular to a motorcycle muffler with an anti-scalding mounting bracket. Background Technology
[0002] The motorcycle muffler is a key component installed in the motorcycle's exhaust system to reduce engine noise, and it is one of the most important parts of a motorcycle. The performance of the muffler not only affects the level of motorcycle noise, but also has a significant impact on engine power, fuel consumption, torque, and other performance characteristics.
[0003] Because mufflers reduce the temperature of exhaust gases, the surface temperature of the muffler cylinder is extremely high, and the cylinder also serves to exchange heat with the air. Therefore, to prevent users' legs from being burned by the muffler, existing motorcycle mufflers are equipped with an anti-scalding device to prevent burns.
[0004] Based on this, Chinese Patent Publication No. CN115263514B discloses an anti-scalding device for a motorcycle muffler, which includes a protective cover eccentrically positioned relative to the muffler cylinder. The protective cover comprises an outer arc-shaped plate and an inner arc-shaped plate coaxially arranged, and two clamping blocks integrally formed at both ends of the outer and inner arc-shaped plates, respectively. The inner wall of the clamping blocks has an arc-shaped surface formed to mate with the outer wall of the muffler, and the arc-shaped surface presses against the outer wall of the muffler. This type of muffler, by providing a protective cover on the right side and above the muffler cylinder, can effectively prevent the user from being scalded; at the same time, the small contact area between the protective cover and the muffler cylinder, along with the heat dissipation grooves and venting chambers on the protective cover, effectively solves the heat dissipation problem of the radiator.
[0005] However, existing heat-resistant brackets still have technical problems with insufficient protection. Specifically, the muffler's internal structure includes baffles, porous tubes, and expansion chambers, which can disperse and guide exhaust sound waves to cancel each other out, such as through compression-sparse wave interference. Simultaneously, it can utilize sound-absorbing materials such as fiberglass and low-carbon steel wire mesh to absorb high-frequency sound energy. Furthermore, by extending the airflow path, such as through a multi-chamber design, exhaust velocity and pressure fluctuations can be reduced, further reducing noise generation. During the aforementioned silencing process, the exhaust gas from the motorcycle engine continuously exchanges heat with the muffler body, resulting in a high surface temperature for the entire motorcycle muffler. Although the inner side of the muffler, when installed on the side of the motorcycle, does not require heat protection because it is in close contact with the body, all other sides pose a risk of burns to the user, especially the outer and upper sides, which are more prone to burns due to frequent contact with the user's limbs. Most existing heat-resistant brackets only consider heat protection for the outer sides, neglecting heat protection for the upper and other areas. Utility Model Content

[0029] Please refer to the following: Figures 1 to 5 This utility model discloses a motorcycle muffler with an anti-scalding mounting bracket, comprising: a connecting flange 1, a connecting pipe 2, a muffler body 3, a mounting connection part 4, and an anti-scalding mounting bracket 5; the connecting flange 1 is disposed at one end of the connecting pipe 2, and the muffler body 3 is disposed at the other end of the connecting pipe 2 relative to the connecting flange 1; the mounting connection part 4 is disposed on one side of the muffler body 3, and at least one anti-scalding mounting bracket 5 is disposed on the upper part and the side of the muffler body 3.
[0030] Specifically, when the motorcycle muffler with anti-scalding mounting bracket of this utility model is in operation, the connecting flange 1 connects one end of the connecting pipe 2 to the engine of an external motorcycle, thereby guiding the exhaust gas generated by the external motorcycle engine into the muffler body 3. When the muffler body 3 is working, it reduces the noise generated during engine exhaust. At this time, the entire muffler 3 will vibrate at a preset amplitude due to the work done by the gas. Moreover, the surface of the muffler body 3 will experience a temperature increase due to continuous heat exchange with the exhaust gas. At this time, the anti-scalding mounting bracket 5 isolates the muffler body 3, preventing the outer surface of the muffler body 3 from directly contacting the skin of the passenger, thereby preventing the heat of the muffler body 3 from being transferred to the anti-scalding mounting bracket 5. This prevents the user's skin from accidentally touching the muffler body 3 and being burned. Furthermore, the motorcycle muffler with anti-scalding mounting brackets of this utility model is provided with at least one anti-scalding mounting bracket 5 on the upper part and side of the muffler body 3, thereby preventing the upper part of the muffler body 3 from scalding the user's feet or the side from scalding the user's calves when the muffler body 3 is in operation; thus, the muffler body 3 is isolated in multiple directions, thereby enhancing the safety protection effect for the user. Therefore, the motorcycle muffler with anti-scalding mounting brackets of this utility model solves the technical problem of how to improve the anti-scalding protection structure of the motorcycle muffler.
[0031] Furthermore, the anti-scalding mounting bracket 5 includes a nut mounting base 501, an anti-scalding bracket 502, a fastener 503, an elastic washer 504, and a flat washer 505; the nut mounting base 501 is fixedly disposed on the upper part or side of the muffler body 3, and the anti-scalding bracket 502 is connected to the nut mounting base 501; the fastener 503 passes through the elastic washer 504, the flat washer 505, and the anti-scalding bracket 502 in sequence and is then connected to the nut mounting base 501.
[0032] Specifically, the anti-scalding bracket 502 has an anti-scalding mounting base 502a and an annular tube 502b; the anti-scalding mounting base 502a is abutted and connected to the nut mounting base 501, and the annular tube 502b passes through the anti-scalding mounting base 502a.
[0033] Specifically, the nut mounting base 501 is used to lift the anti-scalding mounting base 502a away from the surface of the muffler body 3. This allows the annular tube 502b, which passes through the anti-scalding mounting base 502a, to be suspended above the surface of the muffler body 3. This serves two purposes: firstly, it isolates the heat source; secondly, it facilitates rapid heat dissipation. Even if heat is conducted from the nut mounting base 501 towards the anti-scalding bracket 502, the annular tube 502b absorbs the heat and quickly dissipates it into the external air, preventing heat buildup and burns to the user's skin. Furthermore, the elastic washer 504 and flat washer 505 serve two purposes: firstly, they dampen vibrations; secondly, they prevent the fastener 503 from loosening from the nut mounting base 501 during prolonged vibration. The annular tube 502b can be hollow or solid, and the fastener 503 can be a bolt or other threaded connector.
[0034] Furthermore, the mounting connection part 4 can be used to connect the muffler body 3 to the side of the external installation environment such as a motorcycle, thereby also suppressing the vibration of the muffler body 3 to a certain extent. This is because the mounting connection part 4 enhances the installation stability of the muffler body 3 and the external installation environment.
[0035] Furthermore, the muffler body 3 has a cylindrical body 301, a primary connecting part 302, a secondary connecting part 303, a multi-stage energy dissipation part 304, and a tail cover 305; the primary connecting part 302 is disposed in the cylindrical body 301, the primary connecting part 302 extends out from the inside of the cylindrical body 301, one end of the primary connecting part 302 is connected to the connecting pipe 2, and the other end of the primary connecting part 302 is connected to the secondary connecting part 303; the secondary connecting part 303 and the multi-stage energy dissipation part 304 are both disposed in the cylindrical body 301, the secondary connecting part 303 is disposed between the primary connecting part 302 and the multi-stage energy dissipation part 304, the tail cover 305 is disposed at one end of the cylindrical body 301, and the multi-stage energy dissipation part 304 is connected to the tail cover 305.
[0036] Specifically, the primary connecting part 302 has a first connecting pipe 302a, an inner liner plug 302b, and several vent holes 302c; one end of the first connecting pipe 302a is connected to one end of the connecting pipe 2, and the first connecting pipe 302a is inserted into the cylinder 301; the inner liner plug 302b is disposed at the other end of the first connecting pipe 302a relative to the connecting pipe 2; several vent holes 302c are evenly distributed around the periphery of the first connecting pipe 302a, and each vent hole 302c is disposed in the inner cavity of the cylinder 301. Specifically, after the exhaust gas discharged from the external engine is introduced into the first connecting pipe 302a through the connecting pipe 2, it is blocked by the inner liner plug 302b, which forces the gas to diffuse from the vent holes 302c to the periphery of the inner cavity of the cylinder 301, thereby enabling the exhaust gas to undergo preliminary energy dissipation.
[0037] Furthermore, the secondary connecting part 303 has a mesh disc 303a, an inner liner disc 303b, an inner mesh cylinder 303c, and an asbestos layer 303d; the mesh disc 303a is disposed between the primary connecting part 302 and the multi-stage energy dissipation part 304; the inner liner disc 303b is sleeved on the first connecting pipe 302a within the cylinder 301; the inner mesh cylinder 303c connects the mesh disc 303a and the inner liner disc 303b respectively; the inner liner plug 302b and a plurality of vent holes 302c are all disposed within the inner mesh cylinder 303c; and the asbestos layer 303d is disposed around the inner mesh cylinder 303c within the cylinder 301. Specifically, the exhaust gas entering from the first connecting pipe 302a and diffusing around the vent 302c can continue to diffuse through the inner mesh cylinder 303c. There, it is partially absorbed and further energy-dissipated by the asbestos layer 303d, then collects at the inner mesh disc 303a and enters the multi-stage energy dissipation section 304. The inner mesh cylinder 303c is made of a loosely perforated mesh plate rolled up and surrounded, and the mesh disc 303a has several through holes evenly distributed in its center, allowing gas to flow through.
[0038] Furthermore, the multi-stage energy dissipation section 304 includes a single-hole disc 304a, a three-hole disc 304b, a second connecting pipe 304c, a return pipe 304d, and a discharge pipe 304e; the single-hole disc 304a and the three-hole disc 304b are spaced apart in the inner cavity of the cylinder 301, and the second connecting pipe 304c connects the single-hole disc 304a and the three-hole disc 304b respectively; the return pipe 304d and the discharge pipe 304e are interposed in the three-hole disc 304b, and the discharge pipe 304e is connected to the tail cover 305.
[0039] Specifically, the exhaust gas blocked by the secondary connecting part 303 is then shielded by the single-hole disc 304a, and then guided by the second connecting pipe 304c to the cavity after the three-hole disc 304b. It then flows back from the return pipe 304d to the space between the single-hole disc 304a and the three-hole disc 304b, and finally flows out into the external atmosphere from the discharge pipe 304e. Thus, through multi-stage reciprocating energy dissipation, the noise generated during exhaust can be further reduced, thereby achieving the purpose of noise reduction.
[0040] In summary, this utility model discloses a motorcycle muffler with an anti-scalding mounting bracket, comprising a connecting flange 1, a connecting pipe 2, a muffler body 3, a mounting connection part 4, and an anti-scalding mounting bracket 5. The connecting flange 1 is located at one end of the connecting pipe 2, and the muffler body 3 is located at the other end of the connecting pipe 2, relative to the connecting flange 1. The mounting connection part 4 is located on one side of the muffler body 3, and at least one anti-scalding mounting bracket 5 is provided on the upper part and side of the muffler body 3.

Thus, the muffler body 3 is isolated in multiple directions, enhancing the safety protection for the user.
