[0002] Diesel exhaust contains large amounts of hydrocarbons. While most hydrocarbons pose no direct health risk at low atmospheric concentrations, some, such as 3,4-phenylpyrene (PBP), produced by incomplete fuel combustion, can be carcinogenic even at low atmospheric concentrations. High atmospheric concentrations of other hydrocarbons, such as benzene, toluene, and xylene, can also cause physical deformities and cancer, causing serious harm. Under certain conditions (such as when mixed with atmospheric nitrogen oxides, ozone, and sunlight), some hydrocarbons can transform into secondary pollutants, contributing to harmful photochemical smog.

[0037] The following combination Figures 1 to 6, some embodiments of the present application are described in detail. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0038] An embodiment of the present application discloses a post-processing device, which includes a post-processing device 200 and a fixing device 100. The fixing device 100 includes a base 110 and a connecting assembly. The base 110 is used to be installed on a vehicle. The connecting assembly is connected to the base 110. The end or side of the post-processing device 200 can be selectively detachably connected to the connecting assembly, that is, the end or side of the post-processing device 200 is detachably connected to the connecting assembly.

[0039] In this way, when assembling the after-processing device 200 to the vehicle, if it needs to be installed vertically, it is only necessary to detachably connect the end of the after-processing device 200 to the connecting assembly. Since the connecting assembly is connected to the support member 120, and the support member 120 is connected to the base 110, it is only necessary to fix the base 110 to the vehicle; and if it needs to be installed horizontally, it is only necessary to detachably connect the connecting assembly to the side wall of the after-processing device 200 and then fix the base 110 to the vehicle. In this way, the vertical or horizontal installation of the after-processing device 200 can be achieved through a fixing device 100, which has a wide range of applications and reduces manufacturing costs.

[0040] The connection assembly includes a support member 120 and a connection member 130. The support member 120 is connected to the base 110 and abuts against the end or side of the post-processing device 200 to support the post-processing device 200. The connection member 130 is connected to the support member 120 and is detachably connected to the end or side of the post-processing device 200, thereby fixing the post-processing device 200 vertically or horizontally.

[0041] The post-processing device 200 includes a post-processing body and an outer cover tube 220 sleeved outside the post-processing body. A connecting ring 221 is provided on the outer wall of the outer cover tube 220. The two ends of the post-processing body are respectively an air inlet end cover 210 and an air outlet end cover.

[0042] When the after-treatment device 200 is installed vertically, the support member 120 abuts against the air inlet cover 210 of the after-treatment body, and the connecting member 130 is detachably connected to the air inlet cover 210. When the after-treatment device 200 is installed horizontally, the support member 120 abuts against the connecting ring 221, and the connecting member 130 is detachably connected to the connecting ring 221.

[0043] Specifically, the support member 120 includes a first support tube 121, one end of which is connected to the base 110, and the other end of which abuts against the end or side of the post-processing device 200. The connector 130 is connected to the first support tube 121. This tubular support structure not only provides sufficient strength but also saves materials and reduces costs.

[0044] The shape of the other end of the first support tube 121 matches the shape of the air intake cover 210 and the shape of the connecting ring 221. For example, in the illustrated embodiment, since the air intake cover 210 has a raised portion on the air intake pipe, the other end of the first support tube 121 has a corresponding arc-shaped first matching notch 124, which fits with the raised portion of the air intake cover 210. The end of the connecting ring 221 is flat, so the other end of the first support tube 121 can also be flat.

[0045] Since the first support tube 121 bears the weight of the entire exhaust gas after-treatment device 200 at the bottom, in order to improve the strength of the first support tube 121, the support member 120 also includes a reinforcing plate 123. The shape of the reinforcing plate 123 is adapted to the shape of the inner wall of the first support tube 121. The reinforcing plate 123 is connected to the inner wall of the first support tube 121 by welding or the like.

[0046] The support member 120 also includes a second support tube 122 surrounding the outer circumference of the first support tube 121. One end of the second support tube 122 is connected to the base 110, and the connecting member 130 is also connected to the second support tube 122. In this way, the second support tube 122 can be used to improve the stability of the fixing of the connecting member 130, thereby ensuring the reliability of the connection between the connecting member 130 and the post-processing device 200.

[0047] When the post-processing device 200 is installed vertically, the shape of the other end of the second support tube 122 is also adapted to the shape of the intake end cover 210 . The other end of the second support tube 122 is provided with an arc-shaped second adaptation notch 125 , which is engaged with the raised portion of the intake end cover 210 .

[0048] The first support tube 121 and the second support tube 122 may be connected to the base 110 by welding to ensure connection strength.

[0049] The connecting member 130 includes a first connecting plate 131, and the first connecting plate 131 includes a first plate portion 132 and a second plate portion 133 connected at an angle. The first plate portion 132 is connected to the inner side or outer side of the side wall of the first support tube 121, and the second plate portion 133 is detachably connected to the end or side of the post-processing device 200, that is, the second plate portion 133 is detachably connected to the intake end cover 210 or the connecting ring 221.

[0050] The first connecting plate 131 can be bent by a bending process to form the first plate portion 132 and the second plate portion 133, so that the first plate portion 132 and the second plate portion 133 are an integral structure. Of course, the first plate portion 132 and the second plate portion 133 can also be connected by welding, that is, a separate structure.

[0051] The connecting member 130 also includes a second connecting plate 134, which includes a third plate portion 135 and a fourth plate portion 136 connected at an angle, the third plate portion 135 is connected to the inner side or outer side of the side wall of the second support tube 122, and the fourth plate portion 136 is detachably connected to the end or side of the post-processing device 200.

[0052] The second plate portion 133 and the fourth plate portion 136 are at least partially overlapped, that is, they can be fully overlapped or partially overlapped, and the overlapping parts are connected to the same part of the post-processing device 200 by screws, which is more convenient to operate.

[0053] Of course, in some embodiments, the first plate portion 132 may be fixedly connected to the end of the first support tube 121, and the third plate portion 135 may be fixedly connected to the end of the second support tube 122. Furthermore, the first connecting plate 131 and the second connecting plate 134 may be integrally formed. Alternatively, either the second plate portion 133 or the fourth plate portion 136 may be screwed to the post-processing device 200, i.e., only the first and second plate portions 133 or only the fourth plate portion 136 may be connected to the post-processing device 200.

[0054] There is no specific limitation on the connection method between the connector 130 and the post-processing device 200, and for example, it can be a threaded connection.

[0055] The connection between the first connecting plate 131 and the first supporting tube 121 and the connection between the second connecting plate 134 and the second supporting tube 122 can be screw connection or welding.

[0056] In addition, an embodiment of the present application also discloses a vehicle, which includes the post-processing equipment of the above embodiment and thus also has corresponding structure and beneficial effects.

[0057] In summary, the embodiments of the present application disclose a post-processing device and a vehicle. When the post-processing device 200 is assembled on the vehicle, if vertical installation is required, it is only necessary to detachably connect the end of the post-processing device 200 to the connecting assembly. Since the connecting assembly is connected to the support member 120, and the support member 120 is connected to the base 110, it is only necessary to fix the base 110 to the vehicle; and if horizontal installation is required, it is only necessary to detachably connect the connecting assembly to the side wall of the post-processing device 200 and then fix the base 110 to the vehicle. In this way, the vertical or horizontal installation of the post-processing device 200 can be achieved through a fixing device 100, which has a wide range of applications and reduces manufacturing costs.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
