Description

Technical Field

[0001] The utility model belongs to the technical field of automobile mufflers, in particular to a muffler component in an automobile muffler. Background Art

[0002] A muffler is a device that allows airflow while preventing or reducing sound transmission. It's a crucial measure for eliminating aerodynamic noise. There are many different types of mufflers available, including those that isolate noise, absorb noise with muffler cotton, and employ a multi-chamber structure for progressive noise reduction. Of these, the multi-chamber structure for progressive noise reduction is the most widely used.

[0003] When the existing equipment is in use, vibration is likely to occur during the exhaust process of the exhaust pipe, which may cause damage to the connection of the device. At the same time, the existing device has a poor silencing effect due to its single silencing method. Therefore, we propose a silencing component in a car muffler. Utility Model Content

[0004] The purpose of the utility model is to provide a silencer assembly for an automobile muffler, which solves the problem that the connection of the device is easily damaged due to vibration that easily occurs during the exhaust process of the exhaust pipe, and the problem that the silencer method of the existing device is too single, resulting in poor silencer effect.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The utility model discloses a silencer assembly in an automobile muffler, comprising a fixing mechanism, wherein the fixing mechanism comprises a muffler shell, an outer wall of the muffler shell is fixedly connected with an elastic connecting ring, an outer wall of the elastic connecting ring is rotatably connected with a fixing nut, an outer wall of the muffler shell is provided with a shock absorbing mechanism, the shock absorbing mechanism comprises a plurality of fixing rings, the outer walls of the plurality of fixing rings are fixedly connected with fixing blocks, an inner wall of the muffler shell is provided with a silencer mechanism, the silencer mechanism comprises a positioning rod, and an outer wall of the positioning rod is fixedly connected with a fan blade.

[0007] Through the above technical solution, the gas discharged from the exhaust pipe is sucked into the device through the multiple fan blades connected to the positioning rod, so as to reduce the occurrence of noise during the next step.

[0008] Furthermore, an exhaust cover is fixedly connected to the outer wall of the muffler shell, and a plurality of grille plates are fixedly connected to the outer wall of the exhaust cover.

[0009] Through the above technical solution, by fixing the grille plate, it is prevented that unknown objects enter the device when the car is not working, making it difficult to start the car.

[0010] Furthermore, a sliding groove is provided on the inner wall of the fixing block, a connecting block is slidably connected to the inner wall of the fixing block, and a plurality of positioning holes are provided on the inner wall of the connecting block.

[0011] With the above technical solution, the device is conveniently fixed to the car base by means of a plurality of positioning holes provided on the connecting block, thereby preventing the device from falling during use.

[0012] Furthermore, a plurality of connecting plates are fixedly connected to the outer wall of the fixing block, and a second connecting plate is fixedly connected to the outer wall of the connecting plate.

[0013] Through the above technical solution, the device can be reinforced by fixing the connecting plate and the second connecting plate, thereby preventing the device from falling apart during operation.

[0014] Furthermore, a plurality of dampers are fixedly connected to the outer wall of the second connecting plate, a plurality of springs are fixedly connected to the outer walls of the dampers, and the outer walls of the springs are fixedly connected to the outer wall of the connecting block.

[0015] Through the above technical solution, the vibration generated by the exhaust pipe during the exhaust process is reduced through the up and down movement of the damper and the compression of the spring, thereby reducing the damage to the device.

[0016] Furthermore, an air-permeable plate is fixedly connected to the outer wall of the fan blade, and the outer wall of the air-permeable plate is rotatably connected to the inner wall of the muffler shell.

[0017] Through the above technical solution, the air permeable plate is connected to the fan blade. During the rotation of the air permeable plate, the gas in the device can be drawn into the exhaust groove opened inside the muffler shell, thereby reducing the gas flow rate.

[0018] Furthermore, the outer wall of the air-permeable plate is fixedly connected to a plurality of fixed plates, and the outer walls of the plurality of fixed plates are fixedly connected to a plurality of flow-blocking blocks.

[0019] Through the above technical solution, the movement path of the gas is changed by the multiple flow-blocking blocks connected to the fixed plate, thereby reducing the generation of noise.

[0020] Furthermore, an exhaust slot is provided on the inner wall of the muffler shell, and the outer wall of the fan blade is rotatably connected to the inner wall of the muffler shell.

[0021] Through the above technical solution, the speed of the gas can be effectively reduced through the exhaust groove, so that the gas can be discharged quietly.

[0022] The utility model has the following beneficial effects:

[0023] 1. The utility model provides a damper, wraps an elastic connecting ring on the exhaust pipe of the automobile, and then rotates the fixing nut to squeeze the elastic connecting ring and fix the device on the exhaust pipe. Then, the device is fixed to the base of the automobile through multiple positioning holes opened on the inner wall of the connecting block. The connecting block slides up and down along the sliding groove opened on the inner wall of the fixing block, and squeezes the spring during the movement and causes the damper to start moving up and down. The up and down movement of the damper and the squeezing of the spring are achieved to prevent the connection of the device from being easily damaged due to vibration that is likely to occur during the exhaust process of the exhaust pipe.

[0024] 2. The utility model is provided with an exhaust groove and a breathable plate. During the exhaust process of the exhaust pipe, the air flow will blow multiple fan blades to suck the gas into the muffler shell, and the fan blades are connected to the breathable plate. Therefore, during the rotation of the fan blades, the gas will pass through the breathable plate and be sent into the exhaust groove opened inside the muffler shell. The rotation of the breathable plate causes the gas to rotate in the exhaust groove and reduce the speed of the airflow. The breathable plate is connected to multiple flow-blocking blocks to separate the path of the airflow, thereby increasing the gas flow distance. Finally, the gas with a slowed flow rate will be discharged through the grille plate fixed on the outer wall of the exhaust cover, thereby achieving the goal of sending the gas into the exhaust groove by the rotation of the breathable plate, extending the gas exhaust path, and preventing the problem of poor silencing effect due to the excessively single silencing method of the existing device.

[0025] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
