DETAILED DESCRIPTION

[0021] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0022] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, it is a structural diagram of an impact-vibration-proof three-way catalytic converter provided by an embodiment of the present invention, comprising a three-way catalytic converter housing 1, wherein an air inlet port 11 is arranged at one end of the three-way catalytic converter housing 1, and an exhaust port 12 is arranged at the other end of the three-way catalytic converter housing 1, wherein the air inlet port 11 and the exhaust port 12 are respectively connected to the exhaust pipe of the automobile, wherein the inner cavity of the three-way catalytic converter housing 1 is provided with a plurality of groups of parallelly distributed bearing rings 2, wherein a ceramic carrier 21 is arranged inside the bearing ring 2, and sealing rings 22 are respectively fixedly mounted on the surfaces of the leftmost bearing ring 2 and the rightmost bearing ring 2, wherein the inner cavity of the three-way catalytic converter housing 1 is provided with a positioning mechanism 3 which cooperates with the bearing ring 2, wherein the positioning mechanism 3 comprises a supporting assembly 31 and an adjusting assembly 32, wherein the supporting assembly 31 is located on the inner side wall of the three-way catalytic converter housing 1 and is connected to the bearing ring 2, wherein the supporting assembly 31 is used to apply thrust to the plurality of groups of bearing rings 2 so as to make two adjacent groups of bearing rings 2 fit each other, wherein the three-way catalytic converter housing 1 is provided with a plurality of groups of bearing rings 2, wherein the ceramic carrier 21 is arranged inside the bearing ring 2, and sealing rings 22 are respectively fixedly mounted on the surfaces of the leftmost bearing ring 2 and the rightmost bearing ring 2, wherein the inner cavity of the three-way catalytic converter housing 1 is provided with a positioning mechanism 3 which cooperates with the bearing ring 2, and wherein the positioning mechanism 3 comprises a supporting assembly 31 and an adjusting assembly 32, wherein the supporting assembly 31 is located on the inner side wall of the three-way catalytic converter housing 1 and is connected to the bearing ring 2, and wherein the supporting assembly 3 The regulating component 32 is located in the inner cavity of the three-way catalytic converter housing 1 and is connected to the supporting component 31. When the bottom wall of the three-way catalytic converter housing 1 is impacted, the regulating component 32 controls the multiple groups of carrying 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 supporting component 31. An air guide mechanism 4 is provided on the surface of the carrying ring 2. The air guide mechanism 4 includes a telescopic sleeve 41, a storage component 42 and a telescopic component 43. The telescopic sleeve 41 is provided with multiple groups. The storage component 42 is located on both sides of the carrying ring 2 and is connected to the telescopic sleeve 41. The storage component 42 is used to control the multiple groups of telescopic sleeves 41 to be in the carrying ring 2. The telescopic component 43 is connected to the telescopic sleeve 41. When two adjacent groups of carrying rings 2 move from the impact point to both sides respectively, the telescopic component 43 controls the multiple groups of telescopic sleeves 41 to extend to the outside of the carrying ring 2 in sequence by cooperating with the storage component 42. The multiple groups of telescopic sleeves 41 are used to form an air guide duct between the two groups of carrying rings 2.

[0024] Initially, the support component 31 supports and positions the multiple groups of supporting rings 2 in the inner cavity of the three-way catalytic converter housing 1, so that the multiple groups of supporting rings 2 are sequentially fitted and connected into a whole, and the automobile exhaust is transported to the inner cavity of the three-way catalytic converter housing 1 through the intake pipe port 11, and the automobile exhaust passes through the ceramic carrier 21 inside the multiple groups of supporting rings 2. The redox agent on the surface of the ceramic carrier 21 can harmlessly treat the exhaust gas, and the treated exhaust gas is discharged to the outside of the three-way catalytic converter housing 1 through the exhaust pipe port 12. When the vehicle is driving, when the corresponding position of the bottom wall of the three-way catalytic converter housing 1 is hit, the adjustment component 32 cooperates with the support component 31 to control the multiple groups of supporting rings 2 and the ceramic carrier 21 to move toward the two sides of the impact point in the inner cavity of the three-way catalytic converter housing 1, which can effectively avoid damage to the supporting rings 2 and the ceramic carrier 21 at the impact point when the three-way catalytic converter housing 1 is hit.

[0025] When multiple groups of supporting rings 2 are fitted in sequence to filter the exhaust gas, the sealing ring 22 seals the gap between the supporting ring 2 and the side wall of the three-way catalytic converter housing 1, and the exhaust gas can only pass through the multiple groups of ceramic carriers 21. At this time, the storage component 42 controls the multiple groups of telescopic sleeves 41 to be in the supporting ring 2 as a whole. When impacted, the supporting rings 2 on both sides of the impact point move in opposite directions. At this time, the two groups of supporting rings 2 at the impact point are separated from each other, and the telescopic component 43 cooperates with the storage component 42 to control the multiple groups of telescopic sleeves 41 on the surface of the two groups of supporting rings 2 to extend to the outside of the supporting ring 2 in sequence. At this time, the multiple groups of telescopic sleeves 41 form an air duct between the two groups of supporting rings 2. Although the two groups of supporting rings 2 are separated from each other, the exhaust gas can still be controlled to pass between the ceramic carriers 21, which can effectively prevent the exhaust gas from flowing outside the supporting ring 2 after the supporting rings 2 on both sides are separated from each other.

[0026] like Figure 2 , Figure 4 , Figure 5 , Figure 6 As shown, as a preferred embodiment of the present invention, the support assembly 31 includes a plurality of guide rods 311 fixedly installed on the two opposite side walls of the three-way catalytic converter housing 1, the guide rods 311 pass through the surface of the sealing ring 22, a plurality of sliding blocks 312 distributed in an annular shape are fixedly installed on the surface of the support ring 2, the sliding blocks 312 are slidably connected to the guide rods 311, and 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 outer side of the guide rod 311 and is connected to the sealing ring 22.

[0027] When in use, the guide rod 311 cooperates with the multiple sets of sliding blocks 312 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 sets of extrusion springs 313 respectively apply thrust to the sealing rings 22 on both sides, thereby making the multiple sets of bearing rings 2 fit together as a whole. The sealing rings 22 seal the gaps on the outside of the bearing rings 2, and the exhaust gas can pass through the ceramic carrier 21 in the three-way catalytic converter housing 1. When the bottom wall of the three-way catalytic converter housing 1 is hit, the adjustment component 32 controls the two sets of bearing rings 2 that fit each other at the impact point to move in opposite directions. At this time, the bearing rings 2 and the ceramic carrier 21 at the impact point move to other places, which can effectively avoid damage to the bearing rings 2 and the ceramic carrier 21 caused by the impact.

[0028] like Figure 2 , Figure 4 , Figure 5As shown, as a preferred embodiment of the present invention, the adjustment component 32 includes an elastic band 321 fixedly installed on two opposite inner sides of the three-way catalytic converter housing 1, the elastic band 321 is located directly below the load-bearing ring 2, a through hole 322 is opened on the surface of the sealing ring 22, the elastic band 321 passes through the through hole 322, and a plurality of groups of parallelly distributed connecting rods 323 are fixedly installed on the surface of the elastic band 321, the top of the connecting rod 323 is connected to the lowest sliding block 312, and a plurality of groups of parallelly distributed cutting blades 324 are fixedly installed on the inner bottom wall of the three-way catalytic converter housing 1, and the plurality of groups of cutting blades 324 are respectively located between two adjacent groups of sliding blocks 312.

[0029] Initially, the cutting blade 324 is below the elastic band 321. When the bottom wall of the three-way catalytic converter housing 1 is hit, the bottom wall of the three-way catalytic converter housing 1 pushes the cutting blade 324 to move upward, and the cutting blade 324 cuts the elastic band 321 from the impact point when moving upward. At this time, the broken elastic band 321 moves toward the two ends of the three-way catalytic converter housing 1 respectively. The elastic band 321 cooperates with the connecting rod 323 to control multiple groups of supporting rings 2 and ceramic carriers 21 to move toward the two sides of the impact point respectively, which can effectively avoid damage to the supporting rings 2 and ceramic carriers 21 caused by the impact.

[0030] like Figure 2 , Figure 3 , Figure 4 , Figure 6 As shown, as a preferred embodiment of the present invention, the storage component 42 includes storage grooves 421 respectively opened on the opposite side walls of two adjacent groups of carrying rings 2, the storage groove 421 is an annular structure, and multiple groups of telescopic sleeves 41 are arranged as annular structures and are sequentially sleeved from the inside to the outside, and multiple groups of telescopic sleeves 41 are slidably installed in the storage grooves 421, and an annular sleeve 422 is slidably installed on the outside of the multiple groups of telescopic sleeves 41, and one end of the sleeve 422 extends to the outside of the carrying ring 2 and is fixedly installed with a control ring 423.

[0031] When in use, the extrusion spring 313 applies thrust to the sealing ring 22, and the multiple groups of bearing rings 2 are fitted together to form a whole. At this time, the control rings 423 on the surfaces of the two adjacent groups of bearing rings 2 are fitted together, and the multiple groups of telescopic sleeves 41 and the sleeve 422 are both in the receiving groove 421. When impacted, the two groups of bearing rings 2 at the impact point move in opposite directions. At this time, the telescopic assembly 43 controls the two groups of control rings 423 to always be in a whole, and the two groups of bearing rings 2 move in opposite directions. The sleeve 422 and the multiple groups of telescopic sleeves 41 move to the outside of the bearing ring 2 in turn, and the sleeve 422 and the multiple groups of telescopic sleeves 41 form an air guide duct between the two groups of bearing rings 2. The exhaust gas always moves in the air guide duct, thereby controlling the exhaust gas to pass through the ceramic carrier, effectively preventing the exhaust gas from passing through the gap outside the bearing ring 2, and effectively improving the exhaust gas treatment effect. It is prevented that the two adjacent groups of bearing rings 2 are separated from each other after the three-way catalytic converter housing 1 is impacted, and the exhaust gas flows from the outside of the bearing ring 2.

[0032] like Figure 2 , Figure 3 , Figure 4 , Figure 6 As shown, as a preferred embodiment of the present invention, the telescopic assembly 43 includes an inner wall of a receiving groove 421 and multiple groups of telescopic grooves 431 respectively opened on the surface of the telescopic sleeve 41, and the inner wall of the telescopic sleeve 41 and the inner wall of the sleeve 422 are respectively fixed with telescopic blocks 432 slidably connected to the telescopic grooves 431, and the two relatively distributed control rings 423 are made of magnetic materials.

[0033] When in use, the telescopic block 432 slides in the telescopic slot 431, and the position of the multiple telescopic sleeves 41 can be conveniently adjusted. When the extrusion spring 313 applies thrust to the carrying ring 2, the two control rings 423 on the surfaces of the two adjacent carrying rings 2 are connected as a whole through magnetic attraction. When impacted, the carrying 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 the sleeve 422 and the multiple telescopic sleeves 41 can be conveniently pulled out of the storage slot 421.

[0034] like Figure 2 , Figure 3 , Figure 4 As shown, as a preferred embodiment of the present invention, a limit rod 5 is fixedly installed in the telescopic slot 431, and the limit rod 5 is slidably connected with the telescopic block 432. The telescopic block 432 slides on the surface of the limit rod 5, which can effectively improve the stability of the telescopic block 432 and the telescopic sleeve 41.

[0035] like Figure 2 , Figure 4 As shown, as a preferred embodiment of the present invention, the elastic band 321 is made of heat-resistant material.

[0036] The working principle of the present invention is: initially, the guide rod 311 cooperates with the multiple groups of sliding blocks 312 to support and position the supporting ring 2, so that the supporting ring 2 is stably in the inner cavity of the three-way catalytic converter housing 1, and the two groups of extrusion springs 313 respectively apply thrust to the sealing rings 22 on both sides, so that the multiple groups of supporting rings 2 are fitted into a whole, and the sealing ring 22 seals the gap on the outside of the supporting ring 2, and the automobile exhaust is transported to the inner cavity of the three-way catalytic converter housing 1 through the intake pipe port 11, and the automobile exhaust passes through the ceramic carrier 21 inside the multiple groups of supporting rings 2. The redox agent on the surface of the ceramic carrier 21 can harmlessly treat the exhaust gas, and the treated exhaust gas is discharged to the outside of the three-way catalytic converter housing 1 through the exhaust pipe port 12.

[0037] When the vehicle is driving, when the corresponding position of the bottom wall of the three-way catalytic converter housing 1 is hit, the bottom wall of the three-way catalytic converter housing 1 pushes the cutting blade 324 to move upward, and the cutting blade 324 cuts the elastic band 321 from the impact point when moving upward. At this time, the disconnected elastic band 321 moves toward the two ends of the three-way catalytic converter housing 1 respectively, and the elastic band 321 cooperates with the connecting rod 323 to control multiple groups of bearing rings 2 and ceramic carriers 21 to move toward both sides of the impact point respectively. At this time, the bearing rings 2 and ceramic carriers 21 at the impact point move to other places, which can effectively avoid damage to the bearing rings 2 and ceramic carriers 21 caused by the impact.

[0038] When impacted, the bearing rings 2 on both sides of the impact point move in opposite directions. At this time, the two groups of control rings 423 always remain as a whole, so that the sleeve 422 and the multiple groups of telescopic sleeves 41 can be easily pulled out from the storage groove 421. The sleeve 422 and the multiple groups of telescopic sleeves 41 form an air duct between the two groups of bearing rings 2. The exhaust gas always moves in the air duct, thereby controlling the exhaust gas to pass through the ceramic carrier, effectively preventing the exhaust gas from passing through the gap outside the bearing ring 2, and effectively improving the exhaust gas treatment effect. It is prevented that the two adjacent groups of bearing rings 2 are separated from each other after the three-way catalytic converter housing 1 is impacted, and the exhaust gas flows from the outside of the bearing ring 2.

[0039] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
