Description

Technical Field

[0001] This utility model relates to the field of muffler technology, and more specifically to an intake pipe for an automotive muffler. Background Technology

[0002] A car muffler is a component used to reduce the noise generated by a motor vehicle's engine. Because the difference in length between the two pipes is equal to half the wavelength of the sound waves emitted by the car, the two sound waves interfere with each other when they are superimposed, thus reducing the sound intensity and achieving the effect of muffler.

[0003] The shortcomings of existing technology: When a car muffler is in use, the exhaust gas from the engine will enter the muffler. The exhaust gas temperature is extremely high. Prolonged exposure to high temperatures may damage the sound insulation materials and metal parts inside the muffler, affecting the normal function of the muffler, thus reducing the sound insulation effect of the muffler and increasing noise. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an automotive muffler intake pipe to solve the problems existing in the background art.

[0006] Preferably, the support plate has a through-hole, and two through-holes are symmetrically arranged. A wind-gathering shell is fixedly connected to the side of the through-hole away from the fin. Two fans are arranged corresponding to the wind-gathering shells. The fans are located on the side of the wind-gathering shell away from the support plate. The wind-gathering shell and the fans are fixedly connected by a connector.

[0007] Preferably, the guide tube has a U-shaped tubular structure, both ends of the guide tube are fixedly connected to the top of the air collector shell, an extension nozzle is fixedly connected to the center of the top of the guide tube, an electric control valve is provided on the top of the extension nozzle, the output end of the electric control valve is fixedly connected to the extension nozzle, and the input end of the electric control valve is fixedly connected to the automotive air conditioning pipeline.

[0008] Preferably, a tripod is fixedly installed on the side of the support plate away from the fins, and a control module is fixedly installed on the top of the tripod.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] This invention addresses the shortcomings of existing technologies. Before entering the muffler body, engine exhaust gas passes through an S-shaped intake pipe. The heat of the exhaust gas is transferred to the fins via the intake pipe. The driver can select the appropriate option on the center console and send an electrical signal to the vehicle's ECU, causing the electronic control valve to open and the fan to start. The vehicle's air conditioning system then enters the air collector housing through the air conditioning pipes and guide pipes. The fan blows the cold air towards the fins, accelerating airflow and rapidly dissipating the heat from the fins. This reduces the temperature of the exhaust gas entering the muffler body. This design effectively solves a series of problems caused by excessively high internal temperatures in the muffler and provides excellent protection for the vehicle's muffler.

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The automobile muffler intake pipe involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] This utility model provides an intake pipe for an automotive muffler, including a muffler body 1. An intake pipe 2 is fixedly installed at the input end of the muffler body 1. The intake pipe 2 has an S-shaped curved structure. Fins 3 are fixedly installed on the surface of the intake pipe 2. Multiple fins 3 are evenly arranged. Fixing plates 4 are fixedly installed on both the left and right sides of the fins 3. The two fixing plates 4 are fixedly connected by a support plate 5. A fan 6 is installed on the side of the support plate 5 away from the fins 3. A guide pipe 7 is provided on the top of the fan 6.

[0021] Furthermore, the support plate 5 has a through-hole, with two symmetrically arranged through-holes. A concentrator shell 51 is fixedly connected to the side of the through-hole away from the fin 3. Two fans 6 are arranged corresponding to the concentrator shell 51, located on the side of the concentrator shell 51 away from the support plate 5. The concentrator shell 51 and the fans 6 are fixedly connected by a connector 52. The guide pipe 7 has a U-shaped tubular structure, with both ends of the guide pipe 7 fixedly connected to the top of the concentrator shell 51. An extension nozzle 71 is fixedly connected to the center of the top of the guide pipe 7. An electric control valve 72 is installed on the top of the extension nozzle 71. The output end of the electric control valve 72 is fixedly connected to the extension nozzle 71, and the input end of the electric control valve 72 is fixedly connected to the car air conditioning pipe. When the air conditioning cold air enters the guide pipe 7 through the air conditioning pipe, the cold air can enter the concentrator shell 51 from both ends of the guide pipe 7. The wind force of the fans 6 blows the cold air toward the fin 3, accelerating the air flow, thereby allowing the heat of the fin 3 to dissipate quickly.

[0022] Furthermore, a tripod 53 is fixedly installed on the side of the support plate 5 away from the fin 3. A control module 73 is fixedly installed on the top of the tripod 53. The input end of the control module 73 is electrically connected to the vehicle ECU. The control module 73 has three output ends. Two fans 6 are electrically connected to the output ends of the control module 73, and the electronically controlled valve 72 is electrically connected to the output ends of the control module 73. The driver can make selections on the center console and send electrical signals to the vehicle ECU. After receiving the electrical signals, the vehicle ECU can send commands to the control module 73. The control module 73 can control the opening and closing of the electronically controlled valve 72 and the opening and closing of the fans 6 according to the commands.

[0023] Furthermore, a support frame 8 is fixedly installed on the top of the tripod 53. Two support frames 8 are symmetrically arranged. A lower arc plate 81 is fixedly connected to the top of the support frame 8. An upper arc plate 82 is set on the top of the lower arc plate 81. A bolt 83 is installed between the upper arc plate 82 and the lower arc plate 81. A nut 84 is threaded to one end of the bolt 83. The guide pipe 7 is located between the upper arc plate 82 and the lower arc plate 81. By pressing the upper arc plate 82 on the top of the guide pipe 7 and tightening the bolt 83 and nut 84, the guide pipe 7 can be supported, the stability of the guide pipe 7 can be increased, and the strength of the overall structure can be improved.

[0024] The working principle of this utility model is as follows: In actual operation, the engine exhaust gas passes through the intake pipe 2 before entering the muffler body 1. When the exhaust gas passes through the intake pipe 2, the heat of the exhaust gas is transferred to the intake pipe 2, and the intake pipe 2 then transfers the heat to the fins 3, and the fins 3 then dissipate the heat to the outside air.

[0025] The driver makes a selection on the center console and sends an electrical signal to the car ECU. After receiving the electrical signal, the car ECU sends a command to the control module 73. After receiving the command, the control module 73 controls the electronic control valve 72 to open and the fan 6 to turn on. At this time, the car's air conditioning cold air enters the guide pipe 7 through the air conditioning pipe. The cold air then enters the air collector 51 from both ends of the guide pipe 7. The fan 6 blows the cold air towards the fins 3, accelerating the air flow, thereby allowing the heat of the fins 3 to dissipate quickly, and thus reducing the temperature of the exhaust gas entering the muffler body 1.
