DETAILED DESCRIPTION

[0020] 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.

[0021] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0022] like Figure 1 , Figure 2 , Figure 4 , Figure 6 As shown, it is a structural diagram of a noise reduction three-way catalytic converter structure provided by an embodiment of the present invention, comprising a shell 1, an intake pipe 11 is arranged at one end of the shell 1, an exhaust pipe 12 is arranged at the other end of the shell 1, a first ceramic carrier 2 is fixedly installed in the inner cavity of the shell 1, a second ceramic carrier 3 located on one side of the first ceramic carrier 2 is slidably installed in the inner cavity of the shell 1, an adjustment component 4 that cooperates with the second ceramic carrier 3 is arranged in the inner cavity of the shell 1, and the adjustment component 4 is used to control the reciprocating movement of the second ceramic carrier 3 in the inner cavity of the shell 1, and a spoiler mechanism 5 is arranged in the inner cavity of the shell 1 between the first ceramic carrier 2 and the second ceramic carrier 3, and the spoiler mechanism 5 includes a spoiler plate 51 and a positioning component 52. The spoiler 51 is provided with a plurality of groups with the rotating component 53, the positioning component 52 is located on the side wall of the first ceramic carrier 2 and connected to the spoiler 51, the positioning component 52 is used to support and position the spoiler 51 between the first ceramic carrier 2 and the second ceramic carrier 3, the rotating component 53 includes a rotating part 531 and a driving part 532, the rotating part 531 is located on the side wall of the first ceramic carrier 2 and connected to the positioning component 52, the driving part 532 is located between the first ceramic carrier 2 and the second ceramic carrier 3 and connected to the rotating part 531, and the driving part 532 controls the rotation of the plurality of spoiler plates 51 between the first ceramic carrier 2 and the second ceramic carrier 3 by cooperating with the rotating part 531.

[0023] When in use, automobile exhaust flows to the inner cavity of the shell 1 through the intake pipe 11, and the automobile exhaust passes through the second ceramic carrier 3 and the first ceramic carrier 2 in turn, and then is discharged through the exhaust pipe 12. The second ceramic carrier 3 and the first ceramic carrier 2 can efficiently process automobile exhaust. When the automobile exhaust flows at a high speed in the inner cavity of the shell 1, the adjustment component 4 controls the second ceramic carrier 3 to move back and forth in the inner cavity of the shell 1, and then the relative position between the first ceramic carrier 2 and the second ceramic carrier 3 can be conveniently adjusted. The reciprocating movement of the second ceramic carrier 3 can change the flow state of the exhaust in the inner cavity of the shell 1 in real time, and can effectively reduce the noise of the exhaust when it flows in the first ceramic carrier 2 and the second ceramic carrier 3. When the second ceramic carrier 3 moves back and forth, the rotating part 531 cooperates with the driving part 532 to control the multiple groups of spoilers 51 to rotate outside the first ceramic carrier 2. The rotation of the spoiler 51 can further disrupt the flow speed and flow trajectory of the exhaust, and further reduce the noise generated when the exhaust flows in the first ceramic carrier 2.

[0024] like Figure 1 , Figure 2 , Figure 5 As shown, as a preferred embodiment of the present invention, the adjustment component 4 includes two groups of first brackets 41 fixedly installed on the inner wall of the shell 1, a first fixed plate 42 is fixedly installed in the middle of the first bracket 41, and a rotating column 43 is rotatably installed on the two groups of first fixed plates 42. The rotating column 43 is provided with a fan blade 44 at one end facing the air intake pipe 11, and two groups of second brackets 45 are fixedly installed on the inner wall of the shell 1, a second fixed plate 46 is fixedly installed in the middle of the second bracket 45, and a vertical rod 47 is rotatably installed on the two groups of second fixed plates 46. A first driven bevel gear plate 48 is fixedly installed at the bottom end of the vertical rod 47, a first active bevel gear plate 49 is fixedly installed on the surface of the rotating column 43, and the first active bevel gear plate 49 is meshingly connected with the first driven bevel gear plate 48, and a control disk 40 is fixedly installed on the top of the vertical rod 47, and a push-pull rod 410 is rotatably installed on the surface of the control disk 40 at a position deviating from the center of the circle, and the end of the push-pull rod 410 away from the control disk 40 is rotatably connected to the side wall of the second ceramic carrier 3.

[0025] The automobile exhaust flows at high speed from the intake pipe 11 toward the inner cavity of the shell 1, and the automobile exhaust pushes the fan blade 44 to rotate. When rotating, the fan blade 44 drives the rotating column 43 to rotate, and the rotating column 43 drives the first active bevel gear plate 49 to rotate. The first active bevel gear plate 49 and the first driven bevel gear plate 48 are engaged and driven to drive the vertical rod 47 to rotate synchronously, and the vertical rod 47 drives the control disk 40 to rotate synchronously. The control disk 40 cooperates with the push-pull rod 410 to conveniently push and pull the second ceramic carrier 3, thereby controlling the second ceramic carrier 3 to reciprocate in the inner cavity of the shell 1.

[0026] like Figure 2 , Figure 3, Figure 4 , Figure 6 As shown, as a preferred embodiment of the present invention, the positioning assembly 52 includes a supporting column 521 rotatably mounted on the surface of the second ceramic carrier 3, a plurality of groups of spoilers 51 are fixedly mounted in a ring shape on the surface of the supporting column 521, and a through hole 522 is opened inwardly on the surface of the supporting column 521.

[0027] When the second ceramic carrier 3 moves back and forth in the inner cavity of the shell 1, the rotating part 531 controls the supporting column 521 to rotate on the surface of the second ceramic carrier 3. The supporting column 521 drives the spoiler 51 to rotate between the first ceramic carrier 2 and the second ceramic carrier 3. The spoiler 51 can change the flow speed and flow trajectory of the automobile exhaust.

[0028] like Figure 2 , Figure 4 , Figure 6 As shown, as a preferred embodiment of the present invention, the rotating part 531 includes a rotating rod 5311 rotatably mounted on the surface of the second ceramic carrier 3, and synchronous gear plates 5312 are fixedly mounted on the surfaces of the rotating rod 5311 and the supporting column 521 respectively, and the two sets of synchronous gear plates 5312 are commonly connected with a synchronous belt 5313.

[0029] When the second ceramic carrier 3 reciprocates in the inner cavity of the shell 1, the driving part 532 drives the rotating rod 5311 to rotate, and the rotating rod 5311 drives the synchronous gear plate 5312 to rotate. The two sets of synchronous gear plates 5312 and the synchronous belt 5313 cooperate with each other to drive the supporting column 521 to rotate at the side wall of the first ceramic carrier 2.

[0030] like Figure 2 , Figure 3 , Figure 4 , Figure 6 As shown, as a preferred embodiment of the present invention, the driving part 532 includes a cross bar 5321 rotatably installed between the inner walls of the shell 1, a telescopic column 5322 is fixedly installed on the side of the second ceramic carrier 3 facing the supporting column 521, and a tooth groove 5323 is opened on the surface of the telescopic column 5322, a fixed tooth plate 5324 is fixedly installed on the surface of the cross bar 5321, and the fixed tooth plate 5324 is meshingly connected with the tooth groove 5323, a second active bevel tooth plate 5325 is fixedly installed on the surface of the cross bar 5321, and a second driven bevel tooth plate 5326 is fixedly installed on the end of the rotating rod 5311, and the second driven bevel tooth plate 5326 is meshingly connected with the second active bevel tooth plate 5325.

[0031] When the second ceramic carrier 3 reciprocates in the inner cavity of the shell 1, it drives the telescopic column 5322 to move synchronously. The tooth groove 5323 on the surface of the telescopic column 5322 engages with the fixed gear plate 5324 for transmission, which can drive the cross bar 5321 to rotate. The cross bar 5321 drives the second active bevel gear plate 5325 to rotate. The second active bevel gear plate 5325 engages with the second driven bevel gear plate 5326 for transmission, which can drive the rotating rod 5311 to rotate.

[0032] like Figure 2 , Figure 3 As shown, as a preferred embodiment of the present invention, a guide rod 6 is fixedly installed on the inner wall of the housing 1 , and the guide rod 6 is slidably connected to the second ceramic carrier 3 .

[0033] The second ceramic carrier 3 slides on the surface of the guide rod 6 , and the guide rod 6 can effectively improve the stability of the second ceramic carrier 3 when sliding.

[0034] like Figure 2 , Figure 4 , Figure 5 As shown, as a preferred embodiment of the present invention, the fan blades 44 and the spoiler 51 are both made of heat-resistant materials.

[0035] The working principle of the present invention is: when in use, automobile exhaust flows to the inner cavity of the shell 1 through the intake pipe 11, and the automobile exhaust passes through the second ceramic carrier 3 and the first ceramic carrier 2 in turn, and then is discharged through the exhaust pipe 12. The second ceramic carrier 3 and the first ceramic carrier 2 can efficiently process the automobile exhaust. When the automobile exhaust flows at a high speed in the inner cavity of the shell 1, the automobile exhaust pushes the fan blades 44 to rotate. The fan blades 44 drive the rotating column 43 to rotate when rotating. The rotating column 43 drives the first active bevel gear plate 49 to rotate. The first active bevel gear plate 49 and the first driven bevel gear plate 48 are engaged in transmission to drive the vertical rod 47 to rotate synchronously. The vertical rod 47 drives the control disk 40 to rotate synchronously. The control disk 40 cooperates with the push-pull rod 410 to conveniently push and pull the second ceramic carrier 3, thereby controlling the second ceramic carrier 3 to reciprocate in the inner cavity of the shell 1. The relative position between the first ceramic carrier 2 and the second ceramic carrier 3 can be conveniently adjusted. The reciprocating movement of the second ceramic carrier 3 can change the flow state of the exhaust gas in the inner cavity of the shell 1 in real time, which can effectively reduce the noise of the exhaust gas when flowing in the first ceramic carrier 2 and the second ceramic carrier 3.

[0036] When the second ceramic carrier 3 moves back and forth in the inner cavity of the shell 1, it drives the telescopic column 5322 to move synchronously. The tooth groove 5323 on the surface of the telescopic column 5322 is meshed with the fixed tooth plate 5324 for transmission, which can drive the cross bar 5321 to rotate. The cross bar 5321 drives the second active bevel tooth plate 5325 to rotate. The second active bevel tooth plate 5325 is meshed with the second driven bevel tooth plate 5326 for transmission, which can drive the rotating rod 5311 to rotate. The rotating rod 5311 drives the synchronous tooth plate 5312 to rotate. The two sets of synchronous tooth plates 5312 cooperate with the synchronous belt 5313 to drive the bearing column 521 to rotate at the side wall of the first ceramic carrier 2. The bearing column 521 drives the spoiler 51 to rotate between the first ceramic carrier 2 and the second ceramic carrier 3. The spoiler 51 can change the flow speed and flow trajectory of the automobile exhaust. The noise generated when the exhaust gas flows in the first ceramic carrier 2 is further reduced.

[0037] 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.
