Technical Field

[0001] The present invention relates to the technical field of three-way catalytic converter devices, and specifically to a three-way catalytic converter that prevents impact and vibration. Background Technique

[0002] Automobile exhaust is one of the main causes of air pollution. Therefore, the treatment of automobile exhaust has always been a research topic for us. Through various scientific researches and experiments, we have invented many automobile exhaust treatment devices, among which there is a three-way catalytic converter. The three-way catalytic converter is the most important off-vehicle purification device installed in the automobile exhaust system. It can convert harmful gases such as carbon monoxide, hydrocarbons, and nitrogen oxides discharged from automobile exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions.

[0003] The three-way catalytic converter is usually directly installed on the exhaust pipe of the automobile chassis. A ceramic carrier is installed inside the three-way catalytic converter, and harmful gases such as carbon monoxide, hydrocarbons, and nitrogen oxides discharged from automobile exhaust are treated by the oxidation and reduction agents on the surface of the ceramic carrier.

[0004] The existing three-way catalytic converters are usually directly fixedly installed at the automobile chassis. When the automobile is driving and encounters road bumps or other collisions, the three-way catalytic converter is easily impacted, which may cause damage to the three-way catalytic converter. Especially the ceramic carrier inside the three-way catalytic converter is easily directly damaged and needs to be replaced when impacted, resulting in poor use effects. Summary of the Invention

Specific embodiments

[0022] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other.

[0023] The following describes in detail the specific implementation of the present invention in combination with specific embodiments.

[0024] Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4As shown in the figure, it is a structural diagram of a three-way catalytic converter for preventing impact and vibration provided by an embodiment of the present invention, including a three-way catalytic converter housing 1. One end of the three-way catalytic converter housing 1 is provided with an air inlet port 11, and the other end of the three-way catalytic converter housing 1 is provided with an exhaust port 12. The air inlet port 11 and the exhaust port 12 are respectively connected to the exhaust pipe of the vehicle. A plurality of groups of load-bearing rings 2 distributed in parallel are arranged in the inner cavity of the three-way catalytic converter housing 1. A ceramic carrier 21 is arranged inside the load-bearing ring 2. Sealing rings 22 are fixedly installed on the surfaces of the leftmost load-bearing ring 2 and the rightmost load-bearing ring 2 respectively. A positioning mechanism 3 that cooperates with the load-bearing ring 2 is arranged in the inner cavity of the three-way catalytic converter housing 1. The positioning mechanism 3 includes a support assembly 31 and an adjustment assembly 32. The support assembly 31 is located on the inner side wall of the three-way catalytic converter housing 1 and is connected to the load-bearing ring 2. The support assembly 31 is used to apply a thrust to a plurality of groups of load-bearing rings 2 so that two adjacent load-bearing rings 2 are in contact with each other. The adjustment assembly 32 is located in the inner cavity of the three-way catalytic converter housing 1 and is connected to the support assembly 31. When the bottom wall of the three-way catalytic converter housing 1 is impacted, the adjustment assembly 32 controls a plurality of groups of load-bearing rings 2 to move from the impact point to both sides in the inner cavity of the three-way catalytic converter housing 1 by cooperating with the support assembly 31. A gas guiding mechanism 4 is arranged on the surface of the load-bearing ring 2. The gas guiding mechanism 4 includes a telescopic sleeve 41, a receiving assembly 42 and a telescopic assembly 43. A plurality of groups of telescopic sleeves 41 are arranged. The receiving assembly 42 is located on both sides of the load-bearing ring 2 and is connected to the telescopic sleeve 41. The receiving assembly 42 is used to control a plurality of groups of telescopic sleeves 41 to be inside the load-bearing ring 2. The telescopic assembly 43 is connected to the telescopic sleeve 41. When two adjacent load-bearing rings 2 move from the impact point to both sides respectively, the telescopic assembly 43 controls a plurality of groups of telescopic sleeves 41 to extend to the outside of the load-bearing ring 2 in sequence by cooperating with the receiving assembly 42. A plurality of groups of telescopic sleeves 41 are used to form a gas guiding pipeline between two load-bearing rings 2.

[0025] Initially, the support assembly 31 supports and positions a plurality of groups of load-bearing rings 2 in the inner cavity of the three-way catalytic converter housing 1, so that a plurality of groups of load-bearing rings 2 are in contact with each other in sequence to form a whole. The vehicle exhaust gas is transported to the inner cavity of the three-way catalytic converter housing 1 through the air inlet port 11. The vehicle exhaust gas passes through the ceramic carrier 21 inside a plurality of groups of load-bearing rings 2. The oxidation reducing agent on the surface of the ceramic carrier 21 can harmlessly treat the exhaust gas. The treated exhaust gas is discharged to the outside of the three-way catalytic converter housing 1 through the exhaust port 12. When the vehicle is running and the corresponding position of the bottom wall of the three-way catalytic converter housing 1 is impacted, the adjustment assembly 32 cooperates with the support assembly 31 to control a plurality of groups of load-bearing rings 2 and the ceramic carrier 21 to move to both sides of the impact point in the inner cavity of the three-way catalytic converter housing 1, which can effectively avoid damage to the load-bearing ring 2 and the ceramic carrier 21 at the impact point when the three-way catalytic converter housing 1 is impacted.

[0026] When multiple sets of bearing rings 2 are successively attached to filter the exhaust gas, the sealing ring 22 seals the gap between the bearing ring 2 and the side wall of the three-way catalytic converter housing 1. The exhaust gas can only pass through the multiple sets of ceramic carriers 21. At this time, the receiving component 42 controls the multiple sets of telescopic sleeves 41 to be entirely within the bearing ring 2. When being impacted, the bearing rings 2 on both sides of the impact point move in opposite directions. At this time, the two bearing rings 2 at the impact point are separated from each other. The telescopic component 43 and the receiving component 42 cooperate with each other, thereby controlling the multiple sets of telescopic sleeves 41 on the surfaces of the two bearing rings 2 to extend to the outside of the bearing ring 2 in sequence. At this time, the multiple sets of telescopic sleeves 41 form a gas guiding pipe between the two bearing rings 2. Although the two bearing rings 2 are separated from each other, the exhaust gas can still be controlled to pass through between the ceramic carriers 21, effectively preventing the exhaust gas from flowing outside the bearing ring 2 after the two bearing rings 2 are separated from each other.

[0027] As Figure 2 , Figure 4 , Figure 5 , Figure 6 shown, as a preferred embodiment of the present invention, the support component 31 includes multiple guide rods 311 fixedly installed on the opposite side walls of the three-way catalytic converter housing 1. The guide rods 311 pass through the surface of the sealing ring 22. Multiple annularly distributed sliding blocks 312 are fixedly installed on the surface of the bearing ring 2. The sliding blocks 312 are slidably connected to the guide rods 311. An extrusion spring 313 is fixedly installed on the inner side wall of the three-way catalytic converter housing 1. The extrusion spring 313 surrounds the outside of the guide rod 311 and is connected to the sealing ring 22.

[0028] During use, the guide rods 311 and the multiple sliding blocks 312 cooperate with each other to support and position the bearing ring 2, so that the bearing ring 2 is stably located in the inner cavity of the three-way catalytic converter housing 1. The two extrusion springs 313 respectively apply a thrust to the sealing rings 22 on both sides, thereby causing the multiple bearing rings 2 to be attached to form a whole. The sealing ring 22 seals the gap outside the bearing ring 2. The exhaust gas can pass through the ceramic carriers 21 in the three-way catalytic converter housing 1. When the bottom wall of the three-way catalytic converter housing 1 is impacted, the adjustment component 32 controls the two bearing rings 2 that are in contact with each other at the impact point to move in opposite directions. At this time, the bearing ring 2 and the ceramic carrier 21 at the impact point move to other places, effectively preventing the impact from damaging the bearing ring 2 and the ceramic carrier 21.

[0029] As Figure 2 , Figure 4 , Figure 5As shown, as a preferred embodiment of the present invention, the adjusting assembly 32 includes an elastic band 321 fixedly installed on the inner sides of the opposite sides of the three-way catalytic converter housing 1. The elastic band 321 is located directly below the bearing ring 2. Through holes 322 are formed on the surface of the sealing ring 22. The elastic band 321 passes through the through holes 322. A plurality of groups of connecting rods 323 distributed side by side are fixedly installed on the surface of the elastic band 321. The top ends of the connecting rods 323 are connected to the lowermost sliding block 312. A plurality of groups of cutting blades 324 distributed side by side are fixedly installed on the inner bottom wall of the three-way catalytic converter housing 1. The plurality of cutting blades 324 are respectively located between adjacent two groups of sliding blocks 312.

[0030] Initially, the cutting blade 324 is located below the elastic band 321. When the bottom wall of the three-way catalytic converter housing 1 is impacted, the bottom wall of the three-way catalytic converter housing 1 pushes the cutting blade 324 to move upward. When the cutting blade 324 moves upward, it cuts the elastic band 321 from the impact point. At this time, the disconnected elastic bands 321 move toward both ends of the three-way catalytic converter housing 1 respectively. The elastic band 321 and the connecting rod 323 cooperate with each other to control the plurality of bearing rings 2 and the ceramic carriers 21 to move toward both sides of the impact point respectively, effectively avoiding damage to the bearing rings 2 and the ceramic carriers 21 caused by the impact.

[0031] As Figure 2 , Figure 3 , Figure 4 , Figure 6 As shown, as a preferred embodiment of the present invention, the storage assembly 42 includes storage grooves 421 respectively formed on the opposite side walls of two adjacent bearing rings 2. The storage grooves 421 are annular structures. A plurality of telescopic sleeves 41 are arranged in an annular structure and sleeved from the inside to the outside in sequence. The plurality of telescopic sleeves 41 are slidably installed in the storage grooves 421. An annular sleeve 422 is slidably installed on the outer sides of the plurality of telescopic sleeves 41. One end of the sleeve 422 extends to the outside of the bearing ring 2 and is fixedly installed with a control ring 423.

[0032] During use, the compression spring 313 applies a thrust to the sealing ring 22. At this time, multiple groups of bearing rings 2 fit together to form a whole. At this time, the control rings 423 on the surfaces of two adjacent groups of bearing rings 2 fit together. Multiple sets of telescopic sleeves 41 and the sleeve 422 are all located in the receiving groove 421. When being impacted, the two bearing rings 2 at the impact point move in opposite directions. At this time, the telescopic assembly 43 controls the two control rings 423 to always be a whole. The two bearing rings 2 move in opposite directions, and the sleeve 422 and multiple sets of telescopic sleeves 41 move to the outside of the bearing rings 2 in sequence. The sleeve 422 and multiple sets of telescopic sleeves 41 form a gas guiding pipeline between the two bearing rings 2. The tail gas always moves in the gas guiding pipeline, thereby controlling the tail gas to pass through the ceramic carrier, effectively preventing the tail gas from passing through the gaps on the outside of the bearing rings 2, and effectively improving the treatment effect of the tail gas. It avoids the separation of two adjacent bearing rings 2 from each other after the three-way catalytic converter housing 1 is impacted, and the tail gas flows from the outside of the bearing rings 2.

[0033] As Figure 2 , Figure 3 , Figure 4 , Figure 6 shown, as a preferred embodiment of the present invention, the telescopic assembly 43 includes telescopic grooves 431 respectively formed on the inner side walls of the receiving groove 421 and the surfaces of multiple sets of telescopic sleeves 41. Telescopic blocks 432 slidably connected to the telescopic grooves 431 are respectively fixedly installed on the inner side walls of the telescopic sleeves 41 and the inner side wall of the sleeve 422. Two relatively distributed control rings 423 are both made of magnetic materials.

[0034] During use, the telescopic blocks 432 slide in the telescopic grooves 431, and the positions of multiple sets of telescopic sleeves 41 can be adjusted conveniently. When the compression spring 313 applies a thrust to the bearing ring 2, the two control rings 423 on the surfaces of two adjacent bearing rings 2 are connected into a whole by magnetic attraction. When being impacted, the bearing rings 2 on both sides of the impact point move in opposite directions. At this time, the two control rings 423 always remain a whole, and thus the sleeve 422 and multiple sets of telescopic sleeves 41 can be conveniently pulled out from the receiving groove 421.

[0035] As Figure 2 , Figure 3 , Figure 4 shown, as a preferred embodiment of the present invention, a limiting rod 5 is fixedly installed in the telescopic groove 431. The limiting rod 5 is slidably connected to the telescopic block 432. The telescopic block 432 slides on the surface of the limiting rod 5, which can effectively improve the stability of the telescopic block 432 and the telescopic sleeve 41.

[0036] As Figure 2 , Figure 4 shown, as a preferred embodiment of the present invention, the elastic band 321 is made of heat-resistant material.

[0037] The working principle of the present invention is as follows: Initially, the guide rod 311 and multiple sliding blocks 312 cooperate with each other to support and position the bearing ring 2, so that the bearing ring 2 is stably located in the inner cavity of the three-way catalytic converter housing 1. Two sets of compression springs 313 respectively apply a thrust force to the sealing rings 22 on both sides, thereby enabling multiple bearing rings 2 to fit together as a whole. The sealing rings 22 seal the gaps on the outer sides of the bearing rings 2. The automobile exhaust gas is transported to the inner cavity of the three-way catalytic converter housing 1 through the air inlet port 11. The automobile exhaust gas passes through the ceramic carriers 21 inside the multiple bearing rings 2. The oxidation reducing agent on the surface of the ceramic carriers 21 can harmlessly treat the exhaust gas. The treated exhaust gas is discharged to the outside of the three-way catalytic converter housing 1 through the exhaust pipe port 12.

[0038] When the vehicle is running and the corresponding position of the bottom wall of the three-way catalytic converter housing 1 is impacted, the bottom wall of the three-way catalytic converter housing 1 pushes the cutting blade 324 to move upward. When the cutting blade 324 moves upward, it cuts the elastic band 321 from the impact point. At this time, the disconnected elastic bands 321 move towards both ends of the three-way catalytic converter housing 1 respectively. The elastic bands 321 cooperate with the connecting rods 323 to control the multiple bearing rings 2 and the ceramic carriers 21 to move towards both sides of the impact point respectively. At this time, the bearing rings 2 and the ceramic carriers 21 at the impact point move to other places, which can effectively avoid damage to the bearing rings 2 and the ceramic carriers 21 caused by the impact.

[0039] When being impacted, the bearing rings 2 on both sides of the impact point move in opposite directions. At this time, the two control rings 423 always remain as a whole, and thus the sleeve 422 and multiple telescopic sleeves 41 can be conveniently pulled out from the storage groove 421. The sleeve 422 and multiple telescopic sleeves 41 form an air guide pipe between the two bearing rings 2. The exhaust gas always moves in the air guide pipe, thereby controlling the exhaust gas to pass through the ceramic carrier, effectively preventing the exhaust gas from passing through the gaps on the outer sides of the bearing rings 2, and effectively improving the treatment effect of the exhaust gas. It avoids the separation of two adjacent bearing rings 2 from each other after the three-way catalytic converter housing 1 is impacted and the exhaust gas flowing from the outer sides of the bearing rings 2.

[0040] The above has described the preferred embodiments of the present invention in detail, but the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the purpose of the present invention.
