The connecting pipe 40 is adapted to communicate with the exhaust gas discharge pipe 97, and the connecting pipe 40 communicates with the second accommodation space 31. The filter element 50 is disposed in the second accommodation space 31, and the filter element 50 is used for filtering exhaust gas.

[0037] As some embodiments of the present application, the exhaust gas treatment device 100 includes one exhaust gas treatment component 99. As some embodiments of the present application, the exhaust gas treatment device 100 includes two exhaust gas treatment components 99.

[0038] It should be noted that the exhaust gas treatment device 100 of the present application can be but is not limited to being applied to experimental devices, vehicles, etc.

[0039] Among them, the mounting member 10 can mount the exhaust gas discharge pipe 97. Specifically, the mounting member 10 can be sleeved outside the exhaust gas discharge pipe 97 so that the exhaust gas treatment component 99 is disposed on the exhaust gas discharge pipe 97.

[0040] The first housing 20 is connected to the mounting member 10. The connection manner between the first housing 20 and the mounting member 10 can be, but is not limited to, snap connection, bolt connection, etc. As some embodiments of the present application, the first housing 20 and the mounting member 10 are connected by snap connection. The first housing 20 can define a first accommodation space 21. The second housing 30 is disposed in the first housing 20. The connection manner between the second housing 30 and the first housing 20 can be, but is not limited to, welding, bolt connection, etc. As some embodiments of the present application, the second housing 30 and the first housing 20 are connected by welding. The second housing 30 can define a second accommodation space 31. The second accommodation space 31 is communicated with the first accommodation space 21, and moreover, the second accommodation space 31 is communicated with the external environment.

[0041] A part of the connecting pipe 40 is disposed in the first accommodation space 21. That is to say, a part of the pipe body of the connecting pipe 40 is disposed in the first accommodation space 21. Another part of the connecting pipe 40 is disposed outside the first accommodation space 21, and moreover, the length of the connecting pipe 40 can be changed. That is to say, the connecting pipe 40 can be elongated, or the connecting pipe 40 can be shortened, so that the connecting pipe 40 is communicated with the exhaust pipe 97 of the vehicle.

[0042] The connecting pipe 40 is communicated with the second accommodation space 31. The filter element 50 is disposed in the second accommodation space 31. The filter element 50 is used for filtering the exhaust gas. That is to say, the exhaust gas of the internal combustion engine (such as a vehicle) can sequentially pass through the exhaust pipe 97, the connecting pipe 40 and lead to the second accommodation space 31. The filter element 50 in the second accommodation space 31 can adsorb and purify the exhaust gas of the vehicle, so that the discharged exhaust gas meets the emission standards.

[0043] As some embodiments of the present application, the filter element 50 further includes: a filter screen, and the filter screen can be configured as a palladium-based metal filter screen. The harmful gases in the vehicle exhaust gas can be adsorbed by the palladium-based filter material and form corresponding compounds to remain in the filter element 50. By configuring the filter screen as a palladium-based metal filter screen, the filter element 50 can have reliable filter adsorption ability.

[0044] As some embodiments of the present application, the filter element 50 can include: carbon nanotubes.

[0045] As some embodiments of the present application, as Figure 1 shown, the filter element 50 can include: a breathable box 94, filter sheets 95 and bamboo charcoal particles 96. The filter sheets 95 are respectively arranged on the top wall and the bottom wall of the breathable box 94, and the bamboo charcoal particles 96 are filled in the breathable box 94.

[0046] It should be noted that the number of the exhaust gas treatment components 99 can be set according to the number of the exhaust pipes 97 of the vehicle. That is to say, the number of the exhaust pipes 97 is the same as that of the exhaust gas treatment components 99 and they are arranged in one-to-one correspondence, so that the exhaust gas treatment device 100 can be adapted to different vehicle models and the versatility of the exhaust gas treatment device 100 can be increased. In addition, by making the mounting member 10 suitable for mounting on the exhaust pipe 97, the exhaust gas treatment component 99 can be arranged on the exhaust pipe 97. And by making the length of the connecting pipe 40 variable, it is convenient for the connecting pipe 40 to be docked with the exhaust pipe 97, reducing the probability of leaving a gap between the connecting pipe 40 and the exhaust pipe 97 and the risk of exhaust gas leakage, which is beneficial to improving the use reliability of the exhaust gas treatment device 100.

[0047] Therefore, by making the length of the connecting pipe 40 variable and suitable for communicating with the exhaust pipe 97, and arranging the filter element 50 in the second accommodation space 31, it is convenient for the exhaust gas treatment device 100 to be docked with the exhaust pipe 97. And the exhaust gas treatment device 100 can be tightly docked with the exhaust pipe 97, so that the exhaust gas discharged from the exhaust pipe 97 can be fully filtered, reducing the probability of exhaust gas leakage, which is beneficial to improving the exhaust gas treatment effect of the vehicle.

[0048] In some embodiments of the present utility model, such as Figure 1 and Figure 5 shown, the mounting member 10 is configured as a collar 11, and the collar 11 is suitable for being sleeved on the outside of the exhaust pipe 97, and the inner diameter of the collar 11 is adjustable.

[0049] Among them, the collar 11 can be sleeved on the outside of the exhaust pipe 97. That is to say, the collar 11 is detachably connected to the exhaust pipe 97. As some embodiments of the present application, a sponge is arranged between the collar 11 and the exhaust pipe 97, so that the collar 11 can be flexibly mounted on the exhaust pipe 97, reducing the probability of wear between the collar 11 and the exhaust pipe 97. And by arranging a sponge between the collar 11 and the exhaust pipe 97, the probability of resonance between the exhaust pipe 97 and the collar 11 can be reduced, and the noise generated by the vibration of the exhaust pipe 97 and the collar 11 can be reduced, which is beneficial to improving the use reliability of the exhaust gas treatment device 100.

[0050] The inner diameter of the collar 11 is adjustable. That is to say, the inner diameter of the collar 11 can be adjusted to make the collar 11 adapt to exhaust pipes 97 of different sizes. As some embodiments of the present application, the collar 11 can be a snap ring, and the collar 11 is sleeved on the outside of the exhaust pipe 97.

[0051] As some embodiments of the present application, such as Figure 5As shown, the collar 11 can be a hoop band. The hoop band has opposite ends in the circumferential direction. The two ends of the hoop band are connected by screws. One end of the hoop band has a fastening pin, and the other end has a nut. The screw is connected between the fastening pin and the nut. The hoop band can be fastened by a bolt connection so that the exhaust gas discharge pipe 97 is fixed to the hoop band.

[0052] By sleeving the collar 11 on the outside of the exhaust gas discharge pipe 97 and making the inner diameter of the collar 11 adjustable, the mounting member 10 can be adapted to exhaust gas discharge pipes 97 of different sizes, and the versatility of the exhaust gas treatment device 100 can be increased.

[0053] In some embodiments of the present invention, as Figures 1-3 shown, the exhaust gas treatment assembly 99 further includes: a connecting rod 60. The connecting rod 60 is rotatably connected to the mounting member 10 and is fixedly connected to the first housing 20, so that both the first housing 20 and the second housing 30 are rotatable relative to the mounting member 10.

[0054] Among them, the way that the connecting rod 60 is rotatably connected to the mounting member 10 can be a shaft-hole connection. As some embodiments of the present application, the exhaust gas treatment device 100 further includes a first pivot shaft. The connecting rod 60 has a first pivot hole, the mounting member 10 has a second pivot hole, and the axes of the first pivot hole and the second pivot hole are collinearly arranged. The first pivot shaft can pass through the first pivot hole and the second pivot hole to make the connecting rod 60 rotatably connected to the mounting member 10.

[0055] The connecting rod 60 is fixedly connected to the first housing 20. The way that the connecting rod 60 is connected to the first housing 20 can be, but is not limited to, welding, bolt connection, etc. As some embodiments of the present application, the connecting rod 60 is connected to the first housing 20 by welding, and the first housing 20 is connected to the second housing 30 by welding, so that both the first housing 20 and the second housing 30 are rotatable relative to the mounting member 10.

[0056] By making the connecting rod 60 rotatably connected to the mounting member 10 and fixedly connecting the connecting rod 60 to the first housing 20, both the first housing 20 and the second housing 30 can be rotatable relative to the mounting member 10. When assembling the exhaust gas treatment device 100 with the exhaust gas discharge pipe 97, the first housing 20 and the second housing 30 can be rotated to a suitable installation position first. After installing the mounting member 10, the first housing 20 and the second housing 30 can be rotated to a position corresponding to the exhaust gas discharge pipe 97, and then the connecting pipe 40 can be adjusted to communicate with the exhaust gas discharge pipe 97. Thus, the assembly difficulty of the exhaust gas treatment device 100 can be reduced, which is beneficial to improving the assembly efficiency of the exhaust gas treatment device 100.

[0057] In some embodiments of the present invention, as Figure 1 and Figure 3As shown, the connecting pipe 40 includes a first connecting sub-pipe 41 and a second connecting sub-pipe 42. The first connecting sub-pipe 41 is adapted to communicate with the exhaust gas discharge pipe 97. The second connecting sub-pipe 42 is connected between the first connecting sub-pipe 41 and the second accommodation space 31, and the length of the second connecting sub-pipe 42 is variable.

[0058] Among them, the first connecting sub-pipe 41 can communicate with the exhaust gas discharge pipe 97. The length of the second connecting sub-pipe 42 can be changed. Moreover, the second connecting sub-pipe 42 is connected between the first connecting sub-pipe 41 and the second accommodation space 31, so that the exhaust gas of the vehicle can flow through the exhaust gas discharge pipe 97, the first connecting sub-pipe 41, the second connecting sub-pipe 42, and the second accommodation space 31 in sequence.

[0059] It can be understood that the length of the first connecting sub-pipe 41 is not adjustable, and the length of the second connecting sub-pipe 42 is adjustable, so that the length of the connecting pipe 40 is adjustable. By making the connecting pipe 40 include the first connecting sub-pipe 41 and the second connecting sub-pipe 42, the rigid first connecting sub-pipe 41 with an unadjustable length can be connected to the exhaust gas discharge pipe 97, which can make the connection between the connecting pipe 40 and the exhaust gas discharge pipe 97 tight. By making the length of the second connecting sub-pipe 42 adjustable, the length of the connecting pipe 40 can be adjusted, which is convenient for the connecting pipe 40 to be docked with the exhaust gas discharge pipe 97.

[0060] In some embodiments of the present invention, as Figure 1 and Figure 3 shown, the second connecting sub-pipe 42 is configured as a corrugated pipe. By making the second connecting sub-pipe 42 configured as a corrugated pipe, the length of the connecting pipe 40 can be made variable, thereby reducing the docking difficulty between the exhaust gas discharge pipe 97 and the connecting pipe 40, improving the use reliability of the exhaust gas treatment device 100. Moreover, the corrugated pipe has good strength and sealing performance, and such a setting can also reduce the probability of exhaust gas leakage from the connecting pipe 40.

[0061] In some embodiments of the present invention, as Figure 1 and Figure 3 shown, the exhaust gas treatment assembly 99 further includes a plurality of sliders 71 and a plurality of pusher blocks 73. The first housing 20 defines a limiting groove 70 and a slideway 72. Limiting grooves 70 are provided on both opposite sides of the first accommodation space 21. The limiting grooves 70 communicate with the first accommodation space 21. The number of slideways 72 is the same as and corresponds one-to-one to the number of limiting grooves 70. The slideways 72 communicate the corresponding limiting grooves 70 and the outside of the first housing 20. The plurality of sliders 71 and the plurality of pusher blocks 73 correspond one-to-one. The plurality of sliders 71 are slidably disposed in the two limiting grooves 70 respectively. The plurality of pusher blocks 73 are slidably disposed in the two slideways 72 and part of the structure is exposed outside the first housing 20. The slider 71 is connected between the first connecting sub-pipe 41 and the corresponding pusher block 73.

[0062] Among them, the number of the sliders 71 is multiple, and the number of the sliders 71 can be, but is not limited to, two, three, etc. As some embodiments of the present application, the number of the sliders 71 is two. The number of the shifting blocks 73 is multiple, and the number of the shifting blocks 73 can be, but is not limited to, two, three, etc. As some embodiments of the present application, the number of the shifting blocks 73 is two.

[0063] The first housing 20 defines a limiting groove 70 and a sliding groove 72. Specifically, the first accommodating space 21 has opposite two sides, and limiting grooves 70 are arranged on both opposite sides of the first accommodating space 21, and the limiting groove 70 is communicated with the first accommodating space 21.

[0064] The number of the sliding grooves 72 is the same as and corresponds one-to-one with the number of the limiting grooves 70. The sliding grooves 72 are communicated with the corresponding limiting grooves 70 and the outside of the first housing 20. As some embodiments of the present application, two limiting grooves 70 are arranged on opposite two sides of the first accommodating space 21, and the number of the sliding grooves 72 is the same as and corresponds one-to-one with the number of the limiting grooves 70.

[0065] The number of the multiple sliders 71 is the same as and corresponds one-to-one with the number of the multiple shifting blocks 73. As some embodiments of the present application, two sliders 71 correspond to two shifting blocks 73 one-to-one. The two sliders 71 are slidably arranged in the two limiting grooves 70 respectively. The size of the slider 71 is adapted to the size of the limiting groove 70 to reduce the risk of the slider 71 moving off position. The two shifting blocks 73 are slidably arranged in the two sliding grooves 72 respectively, and a part of the structure of the shifting block 73 is exposed outside the first housing 20. Both of the two sliders 71 are connected between the first connecting sub-tube 41 and the corresponding shifting block 73.

[0066] As some embodiments of the present application, the slider 71 and the shifting block 73 are connected by a bolt connection. The shifting block 73 has a through hole, and the slider 71 has a threaded hole. The tail gas treatment device 100 further includes a first bolt 93. The first bolt 93 can pass through the through hole and be in threaded cooperation with the threaded hole. When adjusting the first connecting sub-tube 41 to a proper position, the first connecting sub-tube 41 can be fixed by screwing the first bolt 93.

[0067] Such a setting can shift the shifting block 73 along the sliding groove 72 outside the first housing 20, so that the slider 71 slides along the limiting groove 70, thereby facilitating the adjustment of the position of the first connecting sub-tube 41, reducing the docking difficulty between the first connecting sub-tube 41 and the tail gas discharge pipe 97, and being beneficial to improving the use convenience of the tail gas treatment device 100.

[0068] In some embodiments of the present utility model, as Figure 1 shown, along the first direction (i.e., Figure 1In the Z direction (as shown), the first housing 20 and the second housing 30 are stacked, and in the second direction perpendicular to the first direction, the second housing 30 defines an open end 74 communicating with the second accommodation space 31.

[0069] Wherein, in the first direction (i.e., Figure 1 the Z direction as shown), the first housing 20 and the second housing 30 are connected and stacked, and in the second direction perpendicular to the first direction, the second housing 30 defines an open end 74, and the open end 74 is communicated with the second accommodation space 31.

[0070] By making the second housing 30 define an open end 74 communicating with the second accommodation space 31, the difficulty of taking and placing the filter element 50 can be reduced, so as to facilitate the replacement of the filter element 50, which is beneficial to improving the convenience of use of the tail gas treatment device 100.

[0071] In some embodiments of the present invention, such as Figure 1 and Figure 4 as shown, the tail gas treatment assembly 99 further includes: a stopper 75, the stopper 75 is rotatably arranged on the second housing 30, and a part of the structure of the stopper 75 can rotate to the side of the open end 74 away from the second accommodation space 31 to block the filter element 50.

[0072] Wherein, the way of the rotational connection between the stopper 75 and the second housing 30 can be shaft-hole connection. As some embodiments of the present application, the second housing 30 can have a third pivot hole, and the stopper 75 can have a second pivot shaft, and the third pivot hole and the second pivot shaft cooperate with each other so that the stopper 75 and the second housing 30 can be rotatably connected.

[0073] A part of the structure of the stopper 75 can rotate to the side of the open end 74 away from the second accommodation space 31 to block the filter element 50. That is to say, by rotating the stopper 75, the filter element 50 can be blocked to reduce the probability of the filter element 50 detaching from the second accommodation space 31. As some embodiments of the present application, a plane is set, and the normal line of this plane is parallel to the second direction. That is to say, this plane is perpendicular to the second direction. The stopper 75 can rotate to the side of the open end 74 away from the second accommodation space 31, and the stopper 75 can rotate to a position where the orthographic projection of the stopper 75 on this plane and the orthographic projection of the open end 74 on this plane have an overlapping area to block the filter element 50.

[0074] Such a setting reduces the probability of the filter element 50 detaching from the second accommodation space 31, and can facilitate the replacement of the filter element 50 in the second accommodation space 31, which is beneficial to improving the convenience of use of the tail gas treatment device 100.

[0075] In some embodiments of the present invention, such as Figure 1 and Figure 2As shown, the exhaust gas treatment assembly 99 further includes: an exhaust member 76 disposed in the second housing 30.

The connection manner between the exhaust member 76 and the second housing 30 may be, but is not limited to, welding, bolt connection, etc. As some embodiments of the present application, the exhaust member 76 is connected to the second housing 30 by welding. The exhaust member 76 defines an exhaust passage and exhaust holes 77. The number of the exhaust holes 77 is plural, and the number of the exhaust holes 77 may be, but is not limited to, four, five, etc. As some embodiments of the present application, the number of the exhaust holes 77 is five.

[0077] The exhaust passage communicates between the second accommodation space 31 and the plurality of exhaust holes 77, and the plurality of exhaust holes 77 are all in communication with the external environment, so that the vehicle exhaust gas can flow through the second accommodation space 31, the exhaust passage, the exhaust holes 77 in sequence and be discharged to the external environment.

[0078] By providing the exhaust member 76 and making the exhaust member 76 have a plurality of exhaust holes 77, the exhaust gas can be discharged in a split manner, and the kinetic energy contained in the exhaust gas can be dispersed, thereby reducing the noise generated by the exhaust gas emission assembly and endowing the exhaust gas treatment device 100 with a certain noise reduction function.
