[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.

[0033] The following combination Figures 1 to 5 , 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.

[0034] An embodiment of the present application discloses a mounting assembly 100 , which includes a base 110 and a support member 120 . The base 110 is used to be mounted on a vehicle, and the support member 120 is connected to the base 110 . The support member 120 is used to be connected to the intake end cover 210 of the exhaust gas after-treatment device 200 .

[0035] In this way, by connecting the support member 120 to the air intake end cover 210 of the exhaust gas after-treatment device 200, since the support member 120 is connected to the base 110, after the installation assembly 100 and the exhaust gas after-treatment device 200 are connected and fixed, it is only necessary to place the entire assembly vertically in the installation position reserved on the vehicle, and then connect and fix the base 110 to the chassis or frame of the vehicle so that the axial direction of the exhaust gas after-treatment device 200 is set vertically, realizing vertical installation, simplifying the connection structure, reducing manufacturing costs, and will not affect the performance of the exhaust gas after-treatment device 200 itself.

[0036] Specifically, the support member 120 includes a first support tube 121, the first end of the first support tube 121 is connected to the base 110, and the second end of the first support tube 121 is used to connect to the intake end cover 210 of the exhaust gas after-treatment device 200. In this way, the axial support of the exhaust gas after-treatment device 200 by the tubular structure has more reliable stability and ensures the connection strength.

[0037] Among them, the shape of the second end of the first support tube 121 is adapted to the outer surface shape of the air intake end cover 210. For example, in the illustrated embodiment, the air intake end cover 210 is provided with a raised portion due to the air intake pipe 220. Therefore, the second end of the first support tube 121 has a corresponding arc-shaped first adaptation notch 124, and the first adaptation notch 124 is embedded in the raised portion of the air intake end cover 210.

[0038] Because the first support tube 121 bears the weight of the entire exhaust after-treatment device 200 at its bottom, the support member 120 further includes a reinforcing plate 123 connected to the inner side of the first support tube 121 to enhance its strength. Directly welding the first support tube 121 to the intake end cover 210 also reduces tolerance accumulation within the intake end cover 210, simplifying manufacturing.

[0039] Optionally, the support member 120 also includes a second support tube 122 surrounding the first support tube 121, the first end of the second support tube 122 is connected to the base 110, and the second end of the second support tube 122 is used to be sleeved on the outer side of the intake end cover 210 of the exhaust gas after-treatment device 200, thereby further supporting and limiting the exhaust gas after-treatment device 200 and improving the strength.

[0040] Of course, the shape of the second end of the second support tube 122 also needs to be adapted to the air intake pipe 220 , and therefore has an arc-shaped second adaptation notch 125 , which is engaged with the outer wall of the air intake pipe 220 .

[0041] The first support tube 121 and the second support tube 122 are each welded to the intake end cover 210 of the exhaust gas after-treatment device 200. The first support tube 121 and the second support tube 122 are also welded to the base 110. Specifically, the first and second ends of the first support tube 121 are respectively welded to the base 110 and the intake end cover 210 to ensure connection strength. The first and second ends of the second support tube 122 are also welded to the intake end cover 210 to ensure connection strength.

[0042] The structure of the base 110 is not specifically limited in this application; as long as it can be installed on a vehicle to vertically support the exhaust gas after-treatment device 200, it can be used. For example, the base 110 may be a slot-type flange structure, and the support member 120 may be connected to the inner sidewall of the base 110 and / or the annular groove 112 of the base 110. Specifically, the first end of the second support tube 122 is inserted into the annular groove 112 provided on the base 110 and then welded, thereby increasing the welding area between the second support tube 122 and the base 110 and improving the connection strength. The first end of the first support tube 121 is inserted into the inner hole 111 of the base 110 and then welded, that is, the first support tube 121 is welded to the inner sidewall of the base 110, which increases the welding area, reduces welding deformation, and enhances the strength of the product.

[0043] In addition, in some embodiments, the first support tube 121 may also be connected to the end surface of the base 110. At the same time, an annular groove may be provided on the end surface of the base 110 for the first support tube 121 to be inserted and then welded to ensure the connection strength.

[0044] A plurality of through holes 113 may be provided on the base 110 , so that the base 110 can be fixed to the vehicle by fastening members such as screws passing through the through holes 113 .

[0045] Optionally, the mounting assembly 100 further includes an outer cover tube 130, a first end of which is connected to the base 110. The outer cover tube 130 is used to cover the outside of the exhaust gas after-treatment device 200 and is connected to the exhaust gas after-treatment device 200. This can improve the connection strength between the base 110 and the exhaust gas after-treatment device 200 while protecting the exhaust gas after-treatment device 200, thereby improving the overall strength and reliability of the product.

[0046] In addition, the outer cover tube 130 can also be connected to the vehicle, which can improve the installation stability of the exhaust gas after-treatment device 200 on the vehicle.

[0047] Specifically, the outer cover tube 130 includes a cylinder body 131 and a cylinder cover 132. The first end of the cylinder body 131 is connected to the base 110, for example, by welding to improve the connection strength between the base 110 and the cylinder body 131. The inner cavity of the cylinder body 131 is used to partially accommodate the exhaust gas after-treatment device 200. At the same time, the inner wall of the cylinder body 131 is used to connect with the exhaust gas after-treatment device 200. The cylinder cover 132 is connected to the second end of the cylinder body 131, and the cylinder cover 132 is provided with an avoidance port for the exhaust pipe 230 of the exhaust gas after-treatment device 200 to extend out, so as to facilitate the exhaust pipe 230 to extend out.

[0048] The cylinder 131 can be an integral structure or a split structure in which two curved plates are connected end to end. Such a split structure facilitates the installation of the two curved plates after the first support tube 121 and the second support tube 122 are respectively connected to the intake end cover 210, which makes assembly more convenient. At the same time, the connection between the two curved plates of the cylinder 131 is further connected to the exhaust gas after-treatment device 200, which saves installation space. The junction of the two curved plates and the exhaust gas after-treatment device 200 are connected at the same time by fasteners, thereby improving the structural integrity and reducing the setting and use of the connection structure.

[0049] In addition, an embodiment of the present application also discloses an exhaust gas after-treatment device and a vehicle having the exhaust gas after-treatment device, wherein the exhaust gas after-treatment device includes an exhaust gas after-treatment device 200 and the installation assembly 100 of the above embodiment, and therefore also has corresponding structure and beneficial effects.

[0050] In summary, the embodiments of the present application disclose an installation assembly 100, an exhaust gas after-treatment device and a vehicle, by connecting the support member 120 to the air intake end cover 210 of the exhaust gas after-treatment device 200. Since the support member 120 is connected to the base 110, after the installation assembly 100 and the exhaust gas after-treatment device 200 are connected and fixed, it is only necessary to place the entire assembly vertically in the installation position reserved on the vehicle, and then connect and fix the base 110 to the chassis or frame of the vehicle so that the axial direction of the exhaust gas after-treatment device 200 is vertically set, thereby realizing vertical installation, simplifying the connection structure, reducing manufacturing costs, and not affecting the performance of the exhaust gas after-treatment device 200 itself.

[0051] 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.
